Title: Liquid ejecting device

Description:
The present application is based on, and claims priority from JP Application Serial Number 2021-000177, filed Jan. 4, 2021, the disclosure of which is hereby incorporated by reference herein in its entirety. 
     BACKGROUND 
     1. Technical Field 
     The disclosure relates to a liquid ejecting device such as a printer. 
     2. Related Art 
     For example, as in JP 2017-217857 A, there is a printer, which is an example of a liquid ejecting device that discharges ink, which is an example of liquid, from a recording head, which is an example of a recording unit, and performs printing. The printer includes a wiper for wiping off the recording head, and a temperature sensor, which is an example of a temperature detection unit for detecting temperature. 
     The wiper, which has elasticity, is cured, and adhesion to the recording head is reduced, when temperature is low. Thus, the printer changes force for pressing the wiper against the recording head, in accordance with temperature detected by the temperature sensor. Specifically, the printer increases force for pressing the wiper against the recording head when the temperature is low, compared to when the temperature is high. 
     When the temperature is low, viscosity of liquid adhering to a nozzle surface increases compared to when the temperature is high, and it may be difficult to clean the nozzle surface. In particular, when there is unevenness on the nozzle surface, a concaved part of the nozzle surface that is separated from a cleaning unit is less likely to be cleaned, compared to a convex part that is close to the cleaning unit. Therefore, even when the cleaning unit is pressed strongly against the nozzle surface, there is a possibility that the nozzle surface cannot be sufficiently cleaned. 
     SUMMARY 
     A liquid ejecting device that solves the above problem includes a recording unit configured to eject liquid onto a medium in a ejecting direction from a nozzle provided at a nozzle surface to perform recording, a cleaning unit including a pressing unit for cleaning the nozzle surface, and a temperature detection unit configured to detect temperature, wherein the nozzle surface includes a first surface in which the nozzle opens, and a second surface located downstream the first surface in the ejecting direction, and the cleaning unit is configured to perform the cleaning with a distance in the ejecting direction from the first surface to the pressing unit set to a first distance when a detected temperature detected by the temperature detection unit is equal to or greater than a predetermined temperature, and to a second distance shorter than the first distance when the detected temperature is lower than the predetermined temperature.

     The liquid ejecting device  11  includes a temperature detection unit  33  that detects temperature. The temperature detection unit  33  of the present exemplary embodiment is provided at the carriage  21 . The temperature detection unit  33  moves along with the carriage  21  and the recording unit  20 , and detects a temperature around the recording unit  20 . 
     The recording unit  20  has a nozzle surface  36  provided with a nozzle  35 . The recording unit  20  ejects liquid from the nozzle  35  in a ejecting direction Z onto the medium  14  to perform recording. The ejecting direction Z of the present exemplary embodiment is parallel to the Z-axis, and coincides with a vertical direction. Accordingly, the recording unit  20  of the present exemplary embodiment ejects liquid downward. 
     Cleaning Unit 
     As illustrated in  FIG. 2 , the cleaning unit  22  is aligned in the ejecting direction Z with the recording unit  20  located at the maintenance position MP, and faces the nozzle surface  36 . Specifically, the cleaning unit  22  of the present exemplary embodiment is located below a movement region in which the recording unit  20  moves. 
     The cleaning unit  22  includes a wiping mechanism  38  capable of wiping off the nozzle surface  36 . The cleaning unit  22  may include a liquid receiving portion  39  that receives liquid ejected from the nozzle  35  in association with flushing, and a holding unit  40  that holds the wiping mechanism  38  and the liquid receiving portion  39 . The liquid ejecting device  11  may include a rail  41  that guides movement of the cleaning unit  22 , and a detection unit  42  capable of detecting a position of the moving cleaning unit  22 . The detection unit  42  may be, for example, a sensor that detects the cleaning unit  22 , or a linear encoder capable of measuring a movement distance of the cleaning unit  22 . 
     The cleaning unit  22  moves along the rail  41  in a cleaning direction Y 1 , or a return direction Y 2  opposite to the cleaning direction Y 1 . The cleaning direction Y 1  and the return direction Y 2  of the present exemplary embodiment are directions parallel to the Y-axis. The wiping mechanism  38  and the liquid receiving portion  39  of the present exemplary embodiment are held by the holding unit  40  in a state of being aligned in the cleaning direction Y 1 . Specifically, the wiping mechanism  38  is provided adjacent to the liquid receiving portion  39  at a position upstream the liquid receiving portion  39  in the cleaning direction Y 1 . 
     Liquid Accommodating Portion 
     As illustrated in  FIG. 2 , the liquid receiving portion  39  located at a waiting position WP is aligned with the recording unit  20  located at the maintenance position MP in the ejecting direction Z. The liquid receiving portion  39  accommodates liquid ejected from the nozzle  35  as a waste liquid. The liquid receiving portion  39  may include an intake portion  43  that takes in liquid. The intake portion  43  may be formed of an absorbent body capable of absorbing liquid. 
     Wiping Mechanism 
     The wiping mechanism  38  may include a feeding shaft  45 , a second pressing unit  46 , which is an example of a pressing unit, a tension roller  47 , a first pressing unit  48 , which is an example of the pressing unit, a winding shaft  49 , and a frame body  50  that rotatably supports these. The wiping mechanism  38  may include an absorbent member  51  capable of contacting the nozzle surface  36  and absorbing liquid. 
     The first pressing unit  48  is located between the second pressing unit  46  and the liquid receiving portion  39  in the cleaning direction Y 1 . In other words, in the cleaning direction Y 1 , a distance between the first pressing unit  48  and the liquid receiving portion  39  is shorter than a distance between the second pressing unit  46  and the liquid receiving portion  39 . 
     The feeding shaft  45  holds the band-like absorbent member  51  in a state of being wound in a roll shape. The absorbent member  51  fed from the feeding shaft  45  is transported along a transport path. The absorbent member  51  is wound around the second pressing unit  46 , the tension roller  47 , and the first pressing unit  48 , which are provided in order from upstream the transport path. The winding shaft  49  is rotated by driving of a winding motor (not illustrated). The winding shaft  49  winds the absorbent member  51  in a roll shape. The winding motor may rotate at least one of the feeding shaft  45 , the second pressing unit  46 , the tension roller  47 , and the first pressing unit  48 , together with the winding shaft  49 . 
     The feeding shaft  45 , the second pressing unit  46 , the tension roller  47 , the first pressing unit  48 , and the winding shaft  49  are provided, with the X-axis as an axial direction, and support the absorbent member  51 . In the present exemplary embodiment, a direction along a width of the absorbent member  51  is referred to as a width direction X. The width direction X is parallel to the X-axis. 
     As illustrated in  FIG. 2  and  FIG. 3 , the wiping mechanism  38  may include a movement mechanism  52  that moves the first pressing unit  48  and the second pressing unit  46 . The movement mechanism  52  may move the first pressing unit  48  and the second pressing unit  46  individually, or in conjunction with each other. For example, each of the first pressing unit  48  and the second pressing unit  46  is configured to be movable to a cleaning position CP where the nozzle surface  36  can be cleaned, and to an retracted position EP retracted from the cleaning position CP. 
     The movement mechanism  52  locates one of the first pressing unit  48  and the second pressing unit  46  at the cleaning position CP, while locating another at the retracted position EP. Specifically, as illustrated in  FIG. 2 , the movement mechanism  52  locates the first pressing unit  48  at the cleaning position CP, and locates the second pressing unit  46  at the retracted position EP. As illustrated in  FIG. 3 , the movement mechanism  52  locates the second pressing unit  46  at the cleaning position CP, and locates the first pressing unit  48  at the retracted position EP. 
     One of the first pressing unit  48  and the second pressing unit  46 , which is located at the cleaning position CP, presses the absorbent member  51  up from below, and protrudes the absorbent member  51  from an opening  53  formed in the frame body  50 . A part of the absorbent member  51 , which is pressed up by the first pressing unit  48  or the second pressing unit  46  located at the cleaning position CP, serves as a wiping part  54  capable of wiping off the nozzle surface  36 . The retracted position EP is a position moved from the cleaning position CP in the ejecting direction Z, and is a position where the absorbent member  51  does not contact the nozzle surface  36 . 
     As illustrated in  FIG. 4 , the first pressing unit  48  may be formed in a cylindrical shape. The second pressing unit  46  may include a base portion  55 , and a convex portion  56  that protrudes with respect to the base portion  55 . A diameter of the first pressing unit  48  is the same as a diameter of the base portion  55  of the second pressing unit  46 . The second pressing unit  46  may include the plurality of convex portions  56  provided at intervals in the width direction X. The second pressing unit  46  of the present exemplary embodiment includes the four convex portions  56 . A portion between the convex portions  56  in the width direction X is the base portion  55 . In the second pressing unit  46 , the cylindrical base portions  55  and the cylindrical convex portion  56  are alternately aligned in the width direction X. 
     The convex portion  56  protrudes radially from the base portion  55  along an entire circumference of the base portion  55  in a rotational direction Dr, with the base portion  55  as an axis. A diameter of the convex portion  56  is greater than a diameter of the base portion  55 . The convex portion  56  may be formed integrally with the base portion  55 , or may be mounted to the base portion  55 . 
     Recording Unit 
     As illustrated in  FIG. 5 , the recording unit  20  may include a liquid ejecting head  58 , and a support portion  59  that supports the liquid ejecting head  58 . The recording unit  20  may include the plurality of liquid ejecting heads  58 . The recording unit  20  according to the present exemplary embodiment includes the four liquid ejecting heads  58  aligned at intervals along the X-axis. In other words, the recording unit  20  includes the same number of liquid ejecting heads  58  as the convex portions  56  included in the second pressing unit  46 . Since the configuration of each of the liquid ejecting heads  58  is the same, one liquid ejecting head  58  will be described below. 
     In the liquid ejecting head  58 , a large number of openings of the nozzles  35  are aligned at a constant interval in one direction. The plurality of nozzles  35  aligned in a row constitute a nozzle row. The recording unit  20  of the present exemplary embodiment includes a first nozzle row  61  to an eighth nozzle row  68  provided at intervals in the width direction X. 
     Pairs in the first nozzle row  61  to the eighth nozzle row  68  of the present exemplary embodiment are provided in the liquid ejecting heads  58 , respectively. In other words, the first nozzle row  61  and the second nozzle row  62  are provided in the same liquid ejecting head  58 , and the third nozzle row  63  and the fourth nozzle row  64  are provided in the same liquid ejecting head  58 . Similarly, the fifth nozzle row  65  and the sixth nozzle row  66  are provided in the same liquid ejecting head  58 , and the seventh nozzle row  67  and the eighth nozzle row  68  are provided in the same liquid ejecting head  58 . The recording unit  20  may eject a different type of liquid from each nozzle row, or may eject a different type of liquid from each liquid ejecting head  58 . 
     As illustrated in  FIG. 6 , the liquid ejecting head  58  may include a nozzle forming member  69  formed with the nozzle  35 , and a fixing portion  70  that fixes the nozzle forming member  69  to the support portion  59 . A part of the nozzle forming member  69  is exposed from a hole  70   a  formed in the fixing portion  70 . 
     The nozzle surface  36  may include a first surface  71  in which the nozzle  35  is open, a second surface  72  included in the support portion  59 , and a third surface  73  included in the fixing portion  70 . The first surface  71  is a part of a lower surface of the nozzle forming member  69  that is exposed from the hole  70   a . The second surface  72  is located between the first surface  71 , and the first pressing unit  48  and the second pressing unit  46  in the ejecting direction Z. The second surface  72  of the present exemplary embodiment is located below the first surface  71 . The third surface  73  is located between the first surface  71  and the second surface  72  in the ejecting direction Z. The first surface  71  and the third surface  73  are surfaces recessed with respect to the second surface  72 . The first surface  71  is a surface recessed with respect to the third surface  73 . 
     Next, actions of the present exemplary embodiment will be described. 
     When Detected Temperature is Equal to or Greater than Predetermined Temperature 
     As illustrated in  FIG. 2 , when a detected temperature detected by the temperature detection unit  33  is equal to or greater than a predetermined temperature, the first pressing unit  48  cleans the nozzle surface  36 . In other words, the cleaning unit  22  locates the first pressing unit  48  at the cleaning position CP and locates the second pressing unit  46  at the retracted position EP to clean the nozzle surface  36 . 
     As illustrated in  FIG. 7 , the cleaning unit  22  moves from the waiting position WP in the cleaning direction Y 1  to clean the nozzle surface  36 . In other words, the cleaning unit  22  moves the first pressing unit  48 , the second pressing unit  46 , and the liquid receiving portion  39  in the cleaning direction Y 1  to clean the nozzle surface  36 . The cleaning direction Y 1  is a direction in which, when cleaning the nozzle surface  36 , the wiping mechanism  38  moves. 
     The absorbent member  51  wipes off a foreign material such as liquid adhering to the nozzle surface  36 , with the wiping part  54  in contact with the nozzle surface  36 . In other words, the first pressing unit  48  presses the absorbent member  51  against the nozzle surface  36  to clean the nozzle surface  36 . Thus, the cleaning unit  22  performs cleaning with the absorbent member  51  sandwiched between the first pressing unit  48  and the nozzle surface  36 . 
     As illustrated in  FIG. 6 , the first pressing unit  48  sets a distance in the ejecting direction Z from the first surface  71  to the first pressing unit  48  to a first distance L 1  to perform cleaning. When temperature is high, fluidity of liquid is higher than when temperature is low. Therefore, even when there is a gap between the absorbent member  51  and the first surface  71 , liquid L adhering to the first surface  71  contacts the absorbent member  51 , or moves to the absorbent member  51  along the fixing portion  70  and a side wall of the support portion  59 , and is absorbed in the absorbent member  51 . 
     As illustrated in  FIG. 8 , when the first pressing unit  48  passes through the nozzle surface  36 , the control unit  29  stops moving the cleaning unit  22 , and moves the recording unit  20  from the maintenance position MP. Specifically, the control unit  29 , after moving the cleaning unit  22  from the waiting position WP in the cleaning direction Y 1  by a first movement distance M 1 , moves the cleaning unit  22  in the return direction Y 2  by the first movement distance M 1 , and then returns the cleaning unit  22  to the waiting position WP. The control unit  29  moves the cleaning unit  22  in the return direction Y 2  with the recording unit  20  separated from the maintenance position MP. 
     As illustrated in  FIG. 2 , the control unit  29  returns the cleaning unit  22  to the waiting position WP, and returns the recording unit  20  to the maintenance position MP to perform flushing. The recording unit  20  located at the maintenance position MP faces the liquid receiving portion  39  located at the waiting position WP. Therefore, the liquid receiving portion  39  accommodates liquid discharged in association with the flushing. 
     When Detected Temperature is Less than Predetermined Temperature 
     As illustrated in  FIG. 3 , when the detected temperature detected by the temperature detection unit  33  is less than the predetermined temperature, the second pressing unit  46  cleans the nozzle surface  36 . In other words, the cleaning unit  22  locates the first pressing unit  48  at the retracted position EP and locates the second pressing unit  46  at the cleaning position CP to clean the nozzle surface  36 . 
     As illustrated in  FIG. 9 , the cleaning unit  22  moves from the waiting position WP in the cleaning direction Y 1  to clean the nozzle surface  36 . The wiping part  54  contacts the nozzle surface  36  when the wiping mechanism  38  moves in the cleaning direction Y 1 , and wipes off a foreign material such as liquid adhering to the nozzle surface  36 . In other words, the second pressing unit  46  presses the absorbent member  51  against the nozzle surface  36  to clean the nozzle surface  36 . Thus, the cleaning unit  22  performs cleaning with the absorbent member  51  sandwiched between the second pressing unit  46  and the nozzle surface  36 . 
     As illustrated in  FIG. 10 , when the detected temperature is lower than the predetermined temperature, the cleaning unit  22  locates the convex portion  56  at a position that is between the first surface  71  and the base portion  55  in the ejecting direction Z, and that is a position aligned with the first surface  71  in the ejecting direction Z. 
     In the width direction X, a first dimension S 1  of the liquid ejecting head  58  is greater than a second dimension S 2  of the convex portion  56 . The second pressing unit  46  sets a distance in the ejecting direction Z from the first surface  71  to the second pressing unit  46  to a second distance L 2  that is shorter than the first distance L 1  to perform cleaning. The second distance L 2  is shorter than a third distance L 3  from the first surface  71  to the second surface  72  in the ejecting direction Z. 
     When temperature is low, fluidity of liquid is lower than when temperature is high. The second pressing unit  46  presses the absorbent member  51  into the first surface  71  recessed with respect to the support portion  59  to clean the first surface  71  and the second surface  72 . 
     As illustrated in  FIG. 11 , when the second pressing unit  46  passes through the nozzle surface  36 , the control unit  29  stops moving the cleaning unit  22 , and moves the recording unit  20  from the maintenance position MP. Specifically, the control unit  29 , after moving the cleaning unit  22  from the waiting position WP in the cleaning direction Y 1  by a second movement distance M 2 , which is longer than the first movement distance M 1 , moves the cleaning unit  22  in the return direction Y 2  by the second movement distance M 2 , and then returns the cleaning unit  22  to the waiting position WP. The control unit  29  moves the cleaning unit  22  in the return direction Y 2  with the recording unit  20  separated from the maintenance position 
     MP. 
     As illustrated in  FIG. 3 , the control unit  29  returns the cleaning unit  22  to the waiting position WP, and returns the recording unit  20  to the maintenance position MP to perform flushing. The liquid receiving portion  39  accommodates liquid discharged in association with the flushing. 
     Effects of the present exemplary embodiment will now be described. 
     (1) The nozzle surface  36  includes the first surface  71  and the second surface  72 . The second surface  72  is located between the first surface  71 , and the first pressing unit  48  and the second pressing unit  46  in the ejecting direction Z. The first surface  71  located at a position separated from the first pressing unit  48  and the second pressing unit  46  is less likely to be cleaned by the first pressing unit  48  and the second pressing unit  46  compared to the second surface  72 . The ease of cleaning is also affected by temperature. Specifically, when temperature is low, viscosity of the liquid L adhering to the nozzle surface  36  increases compared to when temperature is high, thus cleaning is difficult. In that regard, the cleaning unit  22 , when a detected temperature is lower than a predetermined temperature, sets a distance from the first surface  71  to the first pressing unit  48  and the second pressing unit  46  to be shorter than when the detected temperature is equal to or greater than the predetermined temperature. In other words, when the detected temperature is low and the viscosity of the liquid is high, the second pressing unit  46  approaches the first surface  71  to clean the first surface  71 . Thus, cleaning can be performed well even when temperature changes. 
     (2) When the detected temperature is less than the predetermined temperature, the convex portion  56  included in the second pressing unit  46 , and the first surface  71  included in the nozzle surface  36  are aligned in the ejecting direction Z. At this time, the convex portion  56  is located at a position between the first surface  71  and the base portion  55  in the ejecting direction Z. Thus, in the ejecting direction Z, a distance from the first surface  71  to the convex portion  56  is shorter than a distance from the first surface  71  to the base portion  55 . Accordingly, a distance between the first surface  71  and the second pressing unit  46  can be easily shortened. 
     (3) The cleaning unit  22  includes the first pressing unit  48  and the second pressing unit  46 . The cleaning unit  22  can selectively use the first pressing unit  48  and the second pressing unit  46  in accordance with a detected temperature to perform cleaning well. 
     (4) Along with cleaning of the nozzle surface  36 , the cleaning unit  22  may press liquid adhering to the nozzle surface  36  into the nozzle  35 . The liquid pressed into the nozzle  35  may evaporate over time and clog the nozzle  35 . When temperature is high, liquid is more likely to evaporate than when temperature is low. Therefore, when temperature is high, flushing may be performed quickly after cleaning is performed. In that regard, in the cleaning direction Y 1 , an interval between the first pressing unit  48  that performs cleaning when a detected temperature is equal to or greater than a predetermined temperature and the liquid receiving portion  39  is set to be less than an interval between the second pressing unit  46  that performs cleaning when the detected temperature is lower than the predetermined temperature and the liquid receiving portion  39 . In other words, by providing the first pressing unit  48  at a position close to the liquid receiving portion  39 , the liquid receiving portion  39  can be caused to quickly face the nozzle surface  36  after the nozzle surface  36  is cleaned by the first pressing unit  48 , and the recording unit  20  can be caused to perform flushing. 
     (5) When the first pressing unit  48  is located at the cleaning position CP, the second pressing unit  46  is located at the retracted position EP. When the first pressing unit  48  is located at the retracted position EP, the second pressing unit  46  is located at the cleaning position CP. As a result, one of the first pressing unit  48  and the second pressing unit  46 , which is located at the cleaning position CP, can be used to perform cleaning. Thus, a load on the nozzle surface  36  can be reduced compared to when both the first pressing unit  48  and the second pressing unit  46  are located at the cleaning position CP to perform cleaning. 
     (6) The absorbent member  51  is capable of absorbing liquid. Thus, by performing cleaning while the cleaning unit  22  and the recording unit  20  sandwich the absorbent member  51 , liquid adhering to the nozzle surface  36  can be absorbed, and liquid remaining on the nozzle surface  36  can be reduced. 
     Exemplary Embodiment 2 
     Next, Exemplary Embodiment 2 of the liquid ejecting device will be described with reference to the drawings. Note that, this Exemplary Embodiment 2 is different from Exemplary Embodiment 1 in a wiping mechanism. Further, since other points are substantially the same as those of the first embodiment, duplicate descriptions of the same configuration will be omitted while assigning the same reference signs to the same components. 
     As illustrated in  FIG. 12 , the wiping mechanism  38  may include the feeding shaft  45 , a pressing unit  75 , and the winding shaft  49 . A configuration of the pressing unit  75  of Exemplary Embodiment 2 is the same as the configuration of the second pressing unit  46  of Exemplary Embodiment 1. In other words, the pressing unit  75  of the present exemplary embodiment includes the base portion  55 , and the convex portion  56  that protrudes with respect to the base portion  55 . The base portion  55  and the convex portion  56  are aligned in the width direction X. 
     The pressing unit  75  presses the absorbent member  51  up from below, and protrudes the absorbent member  51  from the opening  53 . A part of the absorbent member  51  that is pressed up by the pressing unit  75  serves as the wiping part  54  capable of contacting the nozzle surface  36 . The movement mechanism  52  reciprocates the pressing unit  75  along the X-axis. In other words, the pressing unit  75  is provided so as to be movable in the width direction X. 
     Next, actions of the present exemplary embodiment will be described. 
     When Detected Temperature is Equal to or Greater than Predetermined Temperature 
     As illustrated in  FIG. 13 , when a detected temperature detected by the temperature detection unit  33  is equal to or greater than a predetermined temperature, the cleaning unit  22  locates the base portion  55  at a position aligned with the first surface  71  in the ejecting direction Z. The pressing unit  75  sets a distance in the ejecting direction Z from the first surface  71  to the pressing unit  75  to a high temperature distance L 4 , which is an example of a first distance, to perform cleaning. 
     The cleaning unit  22  moves from the waiting position WP in the cleaning direction Y 1  to clean the nozzle surface  36 . At this time, the cleaning unit  22  may relatively move the pressing unit  75  and the recording unit  20  at a first speed to perform cleaning. A first movement speed is a speed slower than a second speed when the pressing unit  75  and the recording unit  20  are relatively moved, when the detected temperature is lower than the predetermined temperature. 
     The pressing unit  75  presses the absorbent member  51  against the nozzle surface  36  to clean the nozzle surface  36 . The cleaning unit  22  performs cleaning with the absorbent member  51  sandwiched between the pressing unit  75  and the nozzle surface  36 . 
     When Detected Temperature is Less than Predetermined Temperature 
     As illustrated in  FIG. 14 , when the detected temperature detected by the temperature detection unit  33  is lower than the predetermined temperature, the cleaning unit  22  locates the convex portion  56  at a position that is between the first surface  71  and the base portion  55  in the ejecting direction Z, and that is a position aligned with the first surface  71  in the ejecting direction Z. The pressing unit  75  sets a distance in the ejecting direction Z from the first surface  71  to the pressing unit  75  to the second distance L 2  that is shorter than the high temperature distance L 4  to perform cleaning. 
     The cleaning unit  22  moves from the waiting position WP in the cleaning direction Y 1  to clean the nozzle surface  36 . At this time, the cleaning unit  22  may relatively move the pressing unit  75  and the recording unit  20  at a second speed that is faster than the first speed to perform cleaning. 
     Effects of the present exemplary embodiment will now be described. 
     (7) When a detected temperature is equal to or greater than a predetermined temperature, the base portion  55  included in the pressing unit  75 , and the first surface  71  included in the nozzle surface  36  are aligned in the ejecting direction Z. In other words, depending on whether the base portion  55  or the convex portion  56  is located at a position aligned with the first surface  71  in the ejecting direction Z, the pressing unit  75  can change a distance from the first surface  71  in the ejecting direction Z. Thus, a distance between the first surface  71  and the cleaning unit  22  can be changed by one pressing unit  75 . 
     (8) The pressing unit  75  is provided so as to be movable in the width direction X in which the base portion  55  and the convex portion  56  are aligned. For example, by moving the pressing unit  75  in the width direction X with the first surface  71  and the convex portion  56  aligned in the ejecting direction Z, the convex portion  56  can be moved from a position aligned with the first surface  71 , and the base portion  55  can be moved to a position aligned with the first surface  71 . Accordingly, a distance between the first surface  71  and the pressing unit  75  can be easily changed. 
     (9) Liquid is more likely to flow when temperature is high, compared to when temperature is low. When a detected temperature is equal to or greater than a predetermined temperature, the cleaning unit  22  moves the pressing unit  75  and the recording unit  20  relatively at a first speed that is slower than a second speed to perform cleaning. Thus, even in a case of cleaning performed while a distance between the first surface  71  and the pressing unit  75  is set to the high temperature distance L 4  that is longer than the second distance L 2 , the cleaning can be performed while waiting for the liquid L adhering to the first surface  71  to move. 
     Exemplary Embodiment 3 
     Next, Exemplary Embodiment 3 of the liquid ejecting device will be described with reference to the drawings. Note that, this Exemplary Embodiment 3 is different from Exemplary Embodiment 1 in respective shapes of a recording unit and a pressing unit. Further, since other points are substantially the same as those of the first embodiment, duplicate descriptions of the same configuration will be omitted while assigning the same reference signs to the same components. 
     As illustrated in  FIG. 15 , each nozzle row of the first nozzle row  61  to the eighth nozzle row  68  may have a first nozzle group  77  and a second nozzle group  78 . The first nozzle group  77  and the second nozzle group  78  are located shifted from each other, in the width direction X and the cleaning direction Y 1 , and partially overlap in the cleaning direction Y 1 . The first nozzle group  77  and the second nozzle group  78  are each constituted by the plurality of nozzles  35  aligned in the cleaning direction Y 1 . 
     The recording unit  20  includes the plurality of first surfaces  71 . Specifically, one liquid ejecting head  58  includes the first surface  71  in which the nozzles  35  constituting the first nozzle group  77  open, and the first surface  71  in which the nozzles  35  constituting the second nozzle group  78  open. In the following description, the first surface  71  corresponding to the first nozzle group  77  is also referred to as an upstream surface  79  located upstream in the cleaning direction Y 1 , and the first surface  71  corresponding to the second nozzle group  78  is also referred to as a downstream surface  80  located downstream in the cleaning direction Y 1 . The upstream surface  79  and the downstream surface  80  are provided shifted from each other, in the width direction X and the cleaning direction Y 1 . 
     As illustrated in  FIG. 16 , the pressing unit  75  includes the base portion  55  formed in a cylindrical shape, a first convex portion  81 , which is an example of a convex portion protruding with respect to the base portion  55 , and a second convex portion  82 , which is an example of the convex portion. In other words, the pressing unit  75  includes the plurality of convex portions. The first convex portion  81  and the second convex portion  82  are provided shifted from each other, in the width direction X. The pressing unit  75  has the same number of first convex portions  81  and second convex portions  82  as the liquid ejecting heads  58 . 
     The first convex portion  81  is located at the same position in the width direction X as the upstream surface  79  located at the maintenance position MP. The second convex portion  82  is located at the same position in the width direction X as the downstream surface  80  located at the maintenance position MP. 
     The cleaning unit  22  includes a rotation mechanism  84  that rotates the pressing unit  75 . The pressing unit  75  is provided so as to be rotatable in the rotational direction Dr with the base portion  55  as an axis. The pressing unit  75  rotates in the rotational direction Dr from a reference state illustrated in  FIG. 17  and  FIG. 18 , and returns to the reference state, after being in a first state illustrated in  FIG. 19  and  FIG. 20 , a second state illustrated in  FIG. 21  and  FIG. 22 , and a third state illustrated in  FIG. 23  and  FIG. 24 . 
     As illustrated in  FIG. 17  and  FIG. 18 , the first convex portion  81  and the second convex portion  82  are each provided at a part in the rotational direction Dr with the base portion  55  as the shaft so as to protrude radially from the base portion  55 . The first convex portion  81  and the second convex portion  82  are provided shifted from each other, in the rotational direction Dr. 
     Next, actions of the present exemplary embodiment will be described. 
     When Detected Temperature is Equal to or Greater than Predetermined Temperature 
     As illustrated in  FIG. 16  to  FIG. 18 , when a detected temperature detected by the temperature detection unit  33  is equal to or greater than a predetermined temperature, the cleaning unit  22  relatively moves the pressing unit  75  in the reference state with respect to the recording unit  20  in the cleaning direction Y 1  to perform cleaning. 
     When the pressing unit  75  is in the reference state, a part of the absorbent member  51  pressed by the base portion  55  serves as the wiping part  54 . As such, similar to Exemplary Embodiment 1 illustrated in  FIG. 6 , the cleaning unit  22  sets a distance in the ejecting direction Z between the first surface  71  and the pressing unit  75  to the first distance L 1  to perform cleaning. 
     When Detected Temperature is Less than Predetermined Temperature 
     When a detected temperature is lower than a predetermined temperature, the cleaning unit  22  rotates the pressing unit  75 , to align the first convex portion  81  and the second convex portion  82  with the upstream surface  79  and the downstream surface  80 , respectively, in the ejecting direction Z. 
     As illustrated in  FIG. 15 , the cleaning unit  22  moves the pressing unit  75  in the cleaning direction Y 1  to perform cleaning. As such, the pressing unit  75  sequentially moves to an upstream region Au aligned with the upstream surface  79  in the ejecting direction Z, a central stream region Ac aligned with the upstream surface  79  and the downstream surface  80  in the ejecting direction Z, and a downstream region Ad aligned with the downstream surface  80  in the ejecting direction Z. 
     As illustrated in  FIG. 19  and  FIG. 20 , when moving in the upstream region Au, the cleaning unit  22  brings the pressing unit  75  into a first state. In the pressing unit  75  in the first state, the first convex portion  81  is located at an upper end of the pressing unit  75 . Therefore, a part of the absorbent member  51  pressed by the first convex portion  81  serves as the wiping part  54 . The second convex portion  82  is located below an upper end of the first convex portion  81 . 
     The first convex portion  81  is aligned with the upstream surface  79  in the ejecting direction Z. Similar to Exemplary Embodiment 1 illustrated in  FIG. 10 , the cleaning unit  22  sets a distance in the ejecting direction Z from the upstream surface  79  to the first convex portion  81  to the second distance L 2  to perform cleaning. 
     As illustrated in  FIG. 21  and  FIG. 22 , when moving in the central stream region Ac, the cleaning unit  22  brings the pressing unit  75  into a second state. In the pressing unit  75  in the second state, the first convex portion  81  and the second convex portion  82  are located at the upper end of the pressing unit  75 . Therefore, a part of the absorbent member  51  pressed by the first convex portion  81  and the second convex portion  82  serves as the wiping part  54 . 
     The first convex portion  81  is aligned with the upstream surface  79  in the ejecting direction Z, and the second convex portion  82  is aligned with the downstream surface  80  in the ejecting direction Z. The cleaning unit  22  sets a distance in the ejecting direction Z from the upstream surface  79  to the first convex portion  81  to the second distance L 2 , and sets a distance in the ejecting direction Z from the downstream surface  80  to the second convex portion  82  to the second distance L 2  to perform cleaning. 
     As illustrated in  FIG. 23  and  FIG. 24 , when moving in the downstream region Ad, the cleaning unit  22  brings the pressing unit  75  into a third state. In the pressing unit  75  in the third state, the second convex portion  82  is located at the upper end of the pressing unit  75 . Therefore, a part of the absorbent member  51  pressed by the second convex portion  82  serves as the wiping part  54 . The first convex portion  81  is located below an upper end of the second convex portion  82 . The second convex portion  82  is aligned with the downstream surface  80  in the ejecting direction Z. The cleaning unit  22  sets a distance in the ejecting direction Z from the downstream surface  80  to the second convex portion  82  to the second distance L 2  to perform cleaning. 
     Effects of the present exemplary embodiment will now be described. 
     (10) The pressing unit  75  includes the first convex portion  81  and the second convex portion  82  that are provided shifted from each other, in the width direction X and the rotational direction Dr. As such, by rotating the pressing unit  75  in the rotational direction Dr, the first convex portion  81  and the second convex portion  82  can be aligned with the upstream surface  79  and the downstream surface  80 , respectively. Thus, even when the recording unit  20  includes the upstream surface  79  and the downstream surface  80 , the nozzle surface  36  can be cleaned well. 
     The present exemplary embodiment described above may be modified as follows. The present exemplary embodiment and modified examples thereof to be described below may be implemented in combination within a range in which a technical contradiction does not arise. 
     In Exemplary Embodiment 1 and Exemplary Embodiment 2, the second pressing unit  46  and the pressing unit  75  need not rotate. It is sufficient that the convex portion  56  and the nozzle surface  36  can at least sandwich the absorbent member  51 , and the convex portion  56  may be provided at a part in the rotational direction Dr. 
     In Exemplary Embodiment 1, a diameter of the first pressing unit  48  may be the same as a diameter of the convex portion  56  of the second pressing unit  46 . 
     The cleaning unit  22  may be configured to not include the absorbent member  51 . The first pressing unit  48 , the second pressing unit  46 , and the pressing unit  75  may directly clean the nozzle surface  36 . 
     In Exemplary Embodiment 3, one liquid ejecting head  58  may have one first surface  71 . The pressing unit  75  may include the base portion  55  and the first convex portion  81 . The cleaning unit  22 , when a detected temperature is equal to or greater than a predetermined temperature, may perform cleaning in a reference state in which the base portion  55  is an upper end of the pressing unit  75 , and when the detected temperature is lower than the predetermined temperature, may perform cleaning in a first state in which the first convex portion  81  is the upper end of the pressing unit  75 . 
     The control unit  29  may move the cleaning unit  22  at a constant speed regardless of a detected temperature. 
     The control unit  29 , when a detected temperature is equal to or greater than a predetermined temperature, may move the cleaning unit  22  at a faster speed than when the detected temperature is lower than the predetermined temperature. 
     In Exemplary Embodiment 1, a gap between the first pressing unit  48  and the second pressing unit  46  in the cleaning direction Y 1  may be greater than a dimension of the nozzle surface  36  in the cleaning direction Y 1 . In this case, cleaning may be performed while the first pressing unit  48  and the second pressing unit  46  are located at the cleaning position CP. 
     The liquid receiving portion  39  may be provided separately from the cleaning unit  22 . For example, the liquid receiving portion  39  may be provided at a position aligned with the cleaning unit  22  in the width direction X. The recording unit  20  may move in the width direction X from the maintenance position MP to perform flushing. 
     The cleaning direction Y 1  may be a direction parallel to the X-axis. 
     The recording unit  20  may move along the X-axis to relatively move with respect to the cleaning unit  22 , and cause the cleaning unit  22  to clean the nozzle surface  36 . The recording unit  20  and the cleaning unit  22  may both move to clean the nozzle surface  36 . 
     The temperature detection unit  33  may detect a temperature of the nozzle surface  36 . The temperature detection unit  33  may detect a temperature of liquid in the recording unit  20 . The temperature detection unit  33  may detect a temperature around the cleaning unit  22 . The temperature detection unit  33  may detect an air temperature, which is a temperature of an environment in which the liquid ejecting device  11  is installed. 
     The liquid ejecting device  11  may be a liquid ejecting device that ejects or discharges other liquids other than ink. A state of liquid discharged from the liquid eject device as a small amount of droplets includes granules, tears, and string-like tails. The liquid described herein may be any material as long as the material can be ejected from the liquid ejecting device. For example, the liquid only needs to be a substance in a state of being in a liquid phase, and includes fluid bodies such as a liquid body with high or low viscosity, sol, gel water, other inorganic solvents, organic solvents, solutions, liquid resins, liquid metals, and metal melts. The liquid includes not only liquids as one state of a substance, but also particles of functional material consisting of solid substances such as pigments or metal particles that are dissolved, dispersed, or mixed in a solvent. Representative examples of liquids include inks, liquid crystals, and the like described in the above embodiments. Here, the inks include a general aqueous ink and a solvent ink, and various liquid compositions such as a gel ink, a hot-melt ink. For example, specific examples of the liquid ejecting device include, a device that ejects liquid including materials such as an electrode material and a color material used in manufacture of liquid crystal displays, electroluminescent displays, surface emitting displays, color filters and the like in a dispersed or dissolved form. The liquid ejecting device may be a device ejecting bioorganic substances used for biochip manufacturing, a device used as a precision pipette and ejecting liquid to be a sample, a printing apparatus, a micro dispenser, or the like. The liquid ejecting device may be a device ejecting lubricant to a precision machine such as a clock or a camera in a pinpoint manner, or a device ejecting a transparent resin liquid such as ultraviolet cure resin on a substrate for forming a tiny hemispherical lens, optical lens, or the like used for an optical communication element and the like. The liquid ejecting device may be a device that ejects an etching solution, such as an acid or alkali, to etch a substrate or the like. 
     Hereinafter, technical concepts and effects thereof that are understood from the above-described exemplary embodiments and modified examples will be described. 
     (A) A liquid ejecting device includes a recording unit configured to eject liquid onto a medium in a ejecting direction from a nozzle provided at a nozzle surface to perform recording, a cleaning unit including a pressing unit for cleaning the nozzle surface, and a temperature detection unit configured to detect temperature, wherein the nozzle surface includes a first surface in which the nozzle opens, and a second surface located between the first surface and the pressing unit in the ejecting direction, and the cleaning unit is configured to perform the cleaning with a distance in the ejecting direction from the first surface to the pressing unit set to a first distance when a detected temperature detected by the temperature detection unit is equal to or greater than a predetermined temperature, and to a second distance shorter than the first distance when the detected temperature is lower than the predetermined temperature. 
     According to this configuration, the nozzle surface includes the first surface and the second surface. The second surface is located between the first surface and the pressing unit in the ejecting direction. The first surface located at a position separated from the pressing unit is less likely to be cleaned by the pressing unit compared to the second surface. In that regard, the cleaning unit, when the detected temperature is lower than the predetermined temperature, sets a distance from the first surface to the pressing unit to be shorter than when the detected temperature is equal to or greater than the predetermined temperature. In other words, when the detected temperature is low and viscosity of liquid is high, the pressing unit approaches the first surface to clean the first surface. Thus, cleaning can be performed well even when temperature changes. 
     (B) In the liquid ejecting device, the pressing unit includes a base portion and a convex portion that protrudes with respect to the base portion, and when the detected temperature is lower than the predetermined temperature, the cleaning unit may locate the convex portion at a position that is between the first surface and the base portion in the ejecting direction, and that is a position aligned with the first surface in the ejecting direction. 
     According to this configuration, when the detected temperature is lower than the predetermined temperature, the convex portion included in the pressing unit, and the first surface included in the nozzle surface are aligned in the ejecting direction. At this time, the convex portion is located at a position between the first surface and the base portion in the ejecting direction. Thus, a distance from the first surface to the convex portion in the ejecting direction is shorter than a distance from the first surface to the base portion. Therefore, a distance between the first surface and the pressing unit can be easily shortened. 
     (C) In the liquid ejecting device, the cleaning unit includes a first pressing unit formed in a cylindrical shape, and a second pressing unit that is the pressing unit, and when the detected temperature is equal to or greater than the predetermined temperature, the first pressing unit cleans the nozzle surface, and when the detected temperature is lower than the predetermined temperature, the second pressing unit may clean the nozzle surface. 
     According to this configuration, the cleaning unit includes the first pressing unit and the second pressing unit. The cleaning unit can selectively use the first pressing unit and the second pressing unit in accordance with the detected temperature to perform cleaning well. 
     (D) In the liquid ejecting device, the cleaning unit further includes a liquid receiving portion configured to receive the liquid ejected from the nozzle in association with flushing, and moves the first pressing unit, the second pressing unit, and the liquid receiving portion in a cleaning direction to clean the nozzle surface, and the first pressing unit may be located between the second pressing unit and the liquid receiving portion in the cleaning direction. 
     According to this configuration, in the cleaning direction, an interval between the first pressing unit that performs cleaning when a detected temperature is equal to or greater than a predetermined temperature and the liquid receiving portion is set to be less than an interval between the second pressing unit that performs cleaning when the detected temperature is lower than the predetermined temperature and the liquid receiving portion. In other words, by providing the first pressing unit at a position close to the liquid receiving portion, the liquid receiving portion can be caused to quickly face the nozzle surface after the nozzle surface is cleaned by the first pressing unit, and the recording unit can be caused to perform flushing. 
     (E) In the liquid ejecting device, the cleaning unit includes a first pressing unit and a second pressing unit that is the pressing unit, and each of the first pressing unit and the second pressing unit is configured to be movable to a cleaning position where the nozzle surface can be cleaned, and to an retracted position where the pressing unit is retracted from the cleaning position, and when the detected temperature is equal to or greater than the predetermined temperature, the cleaning unit locates the first pressing unit at the cleaning position and locates the second pressing unit at the retracted position to clean the nozzle surface, and when the detected temperature is lower than the predetermined temperature, the cleaning unit may locate the first pressing unit at the retracted position and locate the second pressing unit at the cleaning position to clean the nozzle surface. 
     According to this configuration, when the first pressing unit is located at the cleaning position, the second pressing unit is located at the retracted position. When the first pressing unit is located at the retracted position, the second pressing unit is located at the cleaning position. As a result, one of the first pressing unit and the second pressing unit, which is located at the cleaning position, can be used to perform cleaning. Thus, a load on the nozzle surface can be reduced compared to when both the first pressing unit and the second pressing unit are located at the cleaning position to perform cleaning. 
     (F) In the liquid ejecting device, when the detected temperature is equal to or greater than the predetermined temperature, the cleaning unit may locate the base portion at a position aligned with the first surface in the ejecting direction. 
     According to this configuration, when the detected temperature is equal to or greater than the predetermined temperature, the base portion included in the pressing unit, and the first surface included in the nozzle surface are aligned in the ejecting direction. In other words, depending on whether the base portion or the convex portion is located at a position aligned with the first surface in the ejecting direction, the pressing unit can change a distance from the first surface in the ejecting direction. Thus, a distance between the first surface and the cleaning unit can be changed by one pressing unit. 
     (G) In the liquid ejecting device, the base portion and the convex portion are aligned in a width direction, and the pressing unit may be provided so as to be movable in the width direction. 
     According to this configuration, the pressing unit is provided so as to be movable in the width direction in which the base portion and the convex portion are aligned. For example, by moving the pressing unit in the width direction in a state in which the first surface and the convex portion are aligned in the ejecting direction, the convex portion is moved from a position aligned with the first surface, and the base portion can be moved to a position aligned with the first surface. Therefore, a distance between the first surface and the pressing unit can be easily changed. 
     (H) In the liquid ejecting device, when the detected temperature is equal to or greater than the predetermined temperature, the cleaning unit relatively moves the pressing unit and the recording unit at a first speed to perform the cleaning, and when the detected temperature is lower than the predetermined temperature, the cleaning unit relatively moves the pressing unit and the recording unit at a second speed to perform the cleaning, and the first speed may be slower than the second speed. 
     Liquid is more likely to flow when temperature is high, compared to when temperature is low. According to this configuration, when a detected temperature is equal to or greater than a predetermined temperature, the cleaning unit relatively moves the pressing unit and the recording unit at the first speed that is slower than the second speed to perform cleaning. Thus, even in a case of cleaning performed while a distance between the first surface and the pressing unit is set to a first distance that is longer than a second distance, the cleaning can be performed while waiting for liquid adhering to the first surface to move. 
     (I) In the liquid ejecting device, the recording unit includes the plurality of first surfaces, the plurality of first surfaces are provided shifted from each other in a width direction and a cleaning direction, the pressing unit includes a base portion formed in a cylindrical shape, and a plurality of convex portions protruding with respect to the base portion, and is provided so as to be rotatable in a rotational direction with the base portion as an axis, the plurality of convex portions are provided shifted from each other in the width direction and the rotational direction, and the cleaning unit relatively moves the pressing unit with respect to the recording unit in the cleaning direction to perform the cleaning, and when the detected temperature is lower than the predetermined temperature, may rotate the pressing unit to align the plurality of convex portions with the plurality of first surfaces, respectively, in the ejecting direction. 
     According to this configuration, the pressing unit includes the plurality of convex portions provided shifted from each other in the width direction and the rotational direction. As such, by rotating the pressing unit in the rotational direction, the plurality of convex portions can be aligned to the plurality of first surfaces, respectively. Thus, even when the recording unit includes the plurality of first surfaces, the nozzle surface can be cleaned well. 
     (J) The liquid ejecting device further includes an absorbent member that can contact the nozzle surface and absorb the liquid, and the cleaning unit may sandwich the absorbent member between the pressing unit and the nozzle surface to perform the cleaning. 
     According to this configuration, the absorbent member is capable of absorbing the liquid. Thus, by sandwiching the absorbent member between the cleaning unit and the recording unit to perform cleaning, liquid adhering to the nozzle surface can be absorbed, and liquid remaining on the nozzle surface can be reduced.
