An object of the present disclosure is to provide a refrigerator having an improved efficiency.

The object is solved by the features of the independent claim <NUM>.

<FIG> is a sectional view illustrating an example of a refrigerator according to an embodiment of the present disclosure. The refrigerator may have a storage chamber W in which goods and the like may be stored. The refrigerator includes a cabinet <NUM> in which the storage chamber W is formed. The refrigerator may further include a door <NUM> that opens and closes the storage chamber W. The door <NUM> may include at least one of a rotatable door <NUM> and an advancing and retracting type (or drawer type) door <NUM>. The cabinet <NUM> may include an outer case <NUM> forming an outer appearance and an inner case <NUM> forming at least one surface for forming the storage chamber W therein.

The storage chamber W may be a storage chamber in which certain kinds of goods which are preferably stored at a specific temperature range are stored. For example, the storage chamber W may be a dedicated storage chamber for storing certain goods that need to be kept warm or cold, for example, alcoholic liquors such as wine and beer, fermented foods, cosmetics, and medical supplies, for example. As one example, the storage chamber for wine can be maintained at a temperature of <NUM> to <NUM>, or a higher temperature than the refrigerating chamber of a normal refrigerator, and may not exceed <NUM>. The temperature of the storage chamber for red wine may be adjusted to <NUM> to <NUM>, the temperature of the storage chamber for white wine may be adjusted to <NUM> to <NUM>. Meanwhile, the temperature of the storage chamber for champagne may be adjusted to about <NUM>.

The temperature of the storage chamber W may be adjusted such that the storage chamber temperature fluctuates between a target temperature upper limit value and a target temperature lower limit value of the storage chamber W. The quality of the goods stored in the storage chamber W may be reduced by the difference between the target temperature upper limit value and the target temperature lower limit value (hereinafter, referred to as storage chamber temperature difference). The refrigerator may be manufactured with a small storage chamber temperature difference according to the type of the goods and may minimize the reduction of the quality of the goods. The storage chamber W of the refrigerator of the present embodiment may be a storage chamber having a smaller storage chamber temperature difference than that of a general refrigerator. Specifically, the storage chamber temperature difference of the storage chamber W may be less than <NUM>, or may be <NUM> as an example. Of course, in a case of considering goods very sensitive to temperature changes, the storage chamber temperature difference may be less than <NUM>.

The refrigerator may include a device capable of adjusting the temperature of the storage chamber W (hereinafter, referred to as a "temperature adjusting device"). The temperature adjusting device may include at least one of cooling device and heating device. The temperature adjusting device may cool or heat the storage chamber W by at least one of conduction, convection, and radiation. For example, a cooling device (or heat exchanger) such as an evaporator <NUM> or a heat absorbing body of a thermoelectric element may be attached to the inner case <NUM> to cool the storage chamber W by conduction. By adding an airflow forming mechanism such as a fan, the air heat-exchanged with the cooling device by convection can be supplied to the storage chamber W.

A heating device such as a heater or a heat generating body of the thermoelectric element may be attached to the inner case <NUM> to heat the storage chamber W by conduction. The addition of an airflow forming mechanism such as a fan may supply heat to the storage chamber W by convection. In the present specification, the cooling device may be defined as a device capable of cooling the storage chamber W, including at least one of the evaporator <NUM>, the heat absorbing body of the thermoelectric element, and the fan. In addition, the heating device may be defined as a device capable of heating the storage chamber W, including at least one of a heater, a heat generating body of the thermoelectric element, and a fan.

The refrigerator includes an inner guide or walls <NUM>. The inner guide <NUM> may partition an inner portion of the inner case <NUM> into a space in which goods are stored and a space in which a temperature adjusting device is located (hereinafter referred to as a "temperature adjusting device chamber"). The temperature adjusting device chamber may be a cooling device chamber and a heating device chamber.

For example, the temperature adjusting device chamber may be located between the inner guide <NUM> and the inner case <NUM>, between the inner guide <NUM> and the outer case <NUM>, or inside the inner guide <NUM>. The inner guide <NUM> may partition a cold air flow path P for supplying cold air to the space where goods are stored and the storage chamber W, and at least one of the cooling device may be provided in the cold air flow path P.

The inner guide <NUM> may partition a space in which goods are stored and a hot air flow path P for supplying heat to the storage chamber W, and at least one of the heating device may be arranged in the hot air flow path P. The inner guide for the cooling device and the inner guide for the heating device may be designed in common and may be manufactured separately. The inner guide <NUM> may form a storage space together with the inner case <NUM>. The inner guide <NUM> may be provided in front of the rear body of the inner case.

The refrigerator may include both a refrigerator having one space having the same storage chamber temperature range of the storage chamber W and a refrigerator having two or more spaces having different storage temperature ranges from each other.

The refrigerator includes a partition member <NUM> arranged vertically or horizontally in order to divide the storage chambers W into two or more spaces (for example, a first space W1 and a second space W2) which may have different storage chamber temperatures range from each other. The refrigerator may further include the partition member <NUM> arranged vertically or horizontally in order to divide the storage chambers W into two or more spaces (for example, a second space W2, a third space W3) which have different storage chamber temperature ranges from each other. The partition member <NUM> may be separately manufactured and then mounted in the inner case <NUM>. The partition member <NUM> may be manufactured by foaming together with a heat insulating material provided between the outer case <NUM> and the inner cases <NUM> and <NUM>.

The two or more spaces may be different in size. For example, the first space W1 may be located at the upper side, the second space W2 may be located at the lower side, and the partition member <NUM> may be arranged so that the size of the first space W1 is larger than the size of the second space W2. The first storage chamber temperature for the first space W may be higher than the second storage chamber temperature for the second space W2.

According to an embodiment, the first storage chamber temperature may be higher than the second storage chamber temperature, the maximum value of the first storage chamber temperature may be greater than the maximum value of the second storage chamber temperature, the average value of the first storage chamber temperature may be greater than the average value of the second storage chamber temperature, and the minimum value of the first storage chamber temperature may be greater than the minimum value of the second storage chamber temperature. The refrigerator may further include a door (hereinafter, a see-through door) through which the user can see the storage chamber through a see-through window without opening the door <NUM> from the outside of the refrigerator, and the see-through door will be described later.

The refrigerator may further include a transparent gasket <NUM> provided on at least one of the see-through door and the partition members <NUM> and <NUM>. When the see-through door closes the storage chamber W, the transparent gasket <NUM> may partition the storage chamber W into two or more spaces having different storage temperature ranges from each other together with the partition members <NUM> and <NUM>.

The refrigerator may further include door opening modules <NUM> and <NUM>' for forcibly opening the door <NUM>. The door opening modules <NUM> and <NUM>' may be a rotatable door opening module <NUM> which can allow the door <NUM> to be rotated more than a predetermined angle without the user holding the door <NUM>, or an advancing and retracting type door opening module <NUM>' which can allow the door <NUM> to be advanced and retracted in a front and rear direction. The door opening modules <NUM> and <NUM>' will be described later. The refrigerator may further include a lifting module <NUM> capable of lifting or lowering the holder <NUM>, and although not illustrated in <FIG>, the lifting module may be located in at least one of the storage chamber and the door.

The refrigerator may include a plurality of doors for opening and closing two or more spaces having different storage temperature ranges from each other. At least one of the plurality of doors may be a see-through door. At least one of the cabinet <NUM> or the plurality of doors may include door opening modules <NUM> and <NUM>'. A lifting module <NUM> for lifting and lowering the holder <NUM> located in the storage chamber to open and close may be provided on at least one of the plurality of doors. For example, the door for the storage chamber located at the top may be a see-through door, and a lifting module <NUM> for lifting and lowering the holder of the storage chamber located at the lower portion may be disposed.

<FIG> is a sectional view illustrating another example of a refrigerator according to an embodiment of the present disclosure. Hereinafter, the storage chamber W illustrated in <FIG> will be described as a first storage chamber W.

The refrigerator may further include at least one first storage chamber W and at least one second storage chamber C that may be temperature-controlled independently of the first storage chamber W. Hereinafter, a detailed description of the same configuration and operation as those of the storage chamber W illustrated in <FIG> will be omitted for the first storage chamber W, and a different configuration and operation from the storage chamber W illustrated in <FIG> will be described.

The second storage chamber C may be a storage chamber having a temperature range lower than the temperature range of the first storage chamber W, and for example, may be a storage chamber having a temperature range of -<NUM> to <NUM> and the second storage chamber C may be a storage chamber which is temperature-controlled based on a target temperature, which is a temperature selected by a user within a temperature range of -<NUM> to <NUM>.

The second storage chamber C may be composed of a switching chamber (or a temperature changing chamber) in which any one of a plurality of temperature ranges may be selected, and may be configured as a non-switching chamber having one temperature range. The switching chamber may be a storage chamber which can be temperature-controlled to a selected temperature range among a plurality of temperature ranges, and the plurality of temperature ranges may include a first temperature range above zero, a second temperature range below zero, and a third temperature range between the first temperature range and the second temperature range.

For example, the user may supply an input to an input unit to select the second storage chamber C as a mode (for example, a refrigerating chamber mode) that is a temperature range above zero, and the temperature range of the second storage chamber C may be selected within a temperature range above zero (for example, <NUM> to <NUM>). The user may supply an input to an input unit to further input a desired temperature in the temperature range above zero, and the target temperature of the second storage chamber C may be a specific temperature (for example, <NUM>) entered by a user in the temperature range (for example, <NUM> to <NUM>) above zero.

The user may supply an input to the input unit and thus select as a mode in which the second storage chamber C is in the temperature range below zero (for example, freezing chamber mode) or a special mode (for example, a mode for storing a certain kind of goods or kimchi storage mode). The first storage chamber W may be a specific goods storage chamber in which a particular kind of goods which is preferably stored at a specific temperature range is stored or mainly a certain kind of goods are stored, and the second storage chamber C may be a non-specific goods storage chamber in which a various kinds of goods may be stored in addition to a specific kind of goods.

Examples of specific goods may include alcoholic beverages including wine, fermented foods, cosmetics, and medical supplies. For example, the first storage chamber W may be a storage chamber in which wine is stored or a wine chamber in which wine is mainly stored, and the second storage chamber C may be a non-wine chamber in which goods other than wine are stored or goods other than wine are mainly stored.

A storage chamber having a relatively small storage chamber temperature difference among the first storage chamber W and the second storage chamber C may be defined as a constant temperature chamber, and a storage chamber having a relatively large storage chamber temperature difference among the first storage chamber W and the second storage chamber C may be defined as a non-constant temperature chamber. Any one of the first storage chamber W and the second storage chamber C may be a priority storage chamber which is controlled in priority, and the other may be a subordinate storage chamber which is controlled secondarily to the priority chamber.

The first goods having a large or expensive quality change according to the temperature change may be stored in the priority storage chamber, and the second goods having a small or low quality change according to the temperature change may be stored in the subordinate storage chamber. The refrigerator may perform a specific operation for the priority storage chamber and a specific operation for the subordinate storage chamber.

The specific operation may include a general operation and a special operation for the storage chamber. A general operation may be defined as a conventional cooling operation for the storage chamber cooling. The special operation may be defined as a defrost operation for defrosting cooling device, a door load response operation that can be performed when predetermined conditions are satisfied after the door is opened, and an initial power supply operation, which is an operation when the power is first supplied to the refrigerator.

The refrigerator may be controlled such that a specific operation for the priority storage chamber is performed first when two operations may be performed simultaneously. Here, the simultaneous operation may be defined in a case where the start condition of the first operation and the start condition of the second operation are satisfied at the same time, as a case where the start condition of the first operation is satisfied and thus the start condition of the second operation is satisfied while the first operation is in progress, and as a case where the start condition of the second operation is satisfied and thus the start condition of the first operation is satisfied while the second operation is in progress.

For example, in the refrigerator, the priority storage chamber may be cooled or heated prior to the subordinate storage chamber when the temperature of the priority storage chamber is not satisfied and the temperature of the subordinate storage chamber is not satisfied. While the cooling device for cooling the subordinate storage chamber is defrosted, if the temperature of the priority storage chamber is not satisfied, the priority storage chamber may be cooled or heated while the cooling device of the subordinate storage chamber is defrosted.

If the temperature of the priority storage chamber is not satisfied while the subordinate storage chamber is in progress of the door load response operation, the priority storage chamber may be cooled or heated during the door load response operation of the subordinate storage chamber. Any one of the first storage chamber W and the second storage chamber C may be a storage chamber in which the temperature is adjusted by the first cooling device and the heating device, and the other may be a storage chamber in which the temperature is adjusted by the second cooling device.

In the refrigerator, a separate receiving member <NUM> may be additionally disposed in at least one of the first space W1 and the second space W2. In the receiving member <NUM>, a separate space S (hereinafter, referred to as a receiving space) may be formed separately from the first space W1 and the second space W2 to accommodate goods. The refrigerator may adjust the receiving space S of the receiving member <NUM> to a temperature range different from that of the first space W1 and the second space W2.

The receiving member <NUM> may be located in the second space W2 located below the first space W1. The receiving space S of the receiving member <NUM> may be smaller than the second space W2. The storage chamber temperature of the receiving space S may be equal to or less than the storage chamber temperature of the second space W2.

In the refrigerator, in order to dispose as many shelves <NUM> as possible in the first storage chamber W, the length of the refrigerator itself in the vertical direction may be longer than the width in the horizontal direction, and in this case, the length of the refrigerator in the vertical direction may be more than twice the width in the horizontal direction. Since the refrigerator may be rolled over if the length in the vertical direction is too long relative to the width in the horizontal direction, the length in the vertical direction may be less than three times the width in the horizontal direction.

Preferred examples of the length in the vertical direction that can store a plurality of the specific goods may be <NUM> to <NUM> times the width in a left and right direction, and the most preferred example may be <NUM> to <NUM> times the width in the left and right direction. Even if the length of the refrigerator in the vertical direction is longer than the width in the left and right direction, in a case where the length of the storage chamber in which the specific goods are substantially stored, for example, the first storage chamber W, in the vertical direction is short, the number of specific goods may not be high. In the refrigerator, the length of the first storage chamber W in the vertical direction may be longer than the length of the second storage chamber C in the vertical direction so that a space for the specific goods may be as large as possible. For example, the length of the first storage chamber W in the vertical direction may be <NUM> times to <NUM> times the length of the second storage chamber C in the vertical direction.

At least one of the first door <NUM> and the second door <NUM> may be a see-through door, and the see-through door will be described later. The refrigerator may further include door opening modules <NUM> and <NUM>' for forcibly opening at least one of the first door <NUM> and the second door <NUM> to the door opening modules <NUM> and <NUM>', and the door opening modules <NUM> and <NUM>' will be described later. In at least one of the first storage chamber W, the second storage chamber C, and the first door <NUM> and the second door <NUM>, a lifting module <NUM> capable of lifting the holder <NUM> may be provided, and the lifting module <NUM> will be described later.

Referring to <FIG>, the refrigerator of the present embodiment may be provided adjacent to other refrigerators. A pair of adjacent refrigerators may be provided in the left and right direction, hereinafter, for convenience of description, the first refrigerator Q1 and the second refrigerator Q2 will be referred for description thereof, and the same configuration of the first refrigerator Q1 and the second refrigerator Q2 as each other will be described using the same reference numerals for convenience of description. In the refrigerator of the present embodiment, a plurality of storage chambers may be located in the left and right direction and the vertical direction in one outer case, such as a side by side type refrigerator or a French door type refrigerator.

At least one of the first refrigerator Q1 and the second refrigerator Q2 may be a refrigerator to which an embodiment of the present disclosure is applied. Although the first refrigerator Q1 and the second refrigerator Q2 have some functions different from each other, the lengths of the first and second refrigerators Q1 and Q2 in the vertical direction may be the same or almost similar so that the overall appearance may give the same or similar feeling when arranged adjacent to each other in the left and right direction.

Each of the first refrigerator Q1 and the second refrigerator Q2 may include each of a first storage chamber and a second storage chamber, and the first storage chamber and the second storage chamber may include a partition member <NUM> partitioning in the vertical direction, respectively. The partition member <NUM> of the first refrigerator Q1 and the partition member <NUM> of the second refrigerator Q2 may overlap in the horizontal direction.

The lower end 6A of the second door <NUM> opening and closing the second storage chamber of the first refrigerator Q1 and the lower end 6A of the second door <NUM> opening and closing the second storage chamber of the second refrigerator Q2 may coincide with each other in the horizontal direction. The lower end 6B of the second door <NUM> opening and closing the second storage chamber of the first refrigerator Q1 and the lower end 6B of the second door <NUM> opening and closing the second storage chamber of the second refrigerator Q2 may coincide with each other in the horizontal direction.

Referring to <FIG>, the refrigerator may include cooling device and heating device that may be independently controlled to control the temperature of the storage chamber W. The refrigerator may include cooling device and heating device for controlling the temperature of at least one storage chamber among a specific goods storage chamber, a constant temperature chamber, and a priority storage chamber.

The refrigerator may be controlled in a plurality of modes for temperature adjusting of the storage chamber W, and the plurality of modes may include a cooling mode E in which the storage chamber W is cooled by the cooling device, a heating mode H in which the storage chamber W is heated by the heating device, and a standby mode D which maintains the current state without cooling or heating the storage chamber W.

The refrigerator may include a temperature sensor for sensing a temperature of the storage chamber W and a controller which may perform the cooling mode E, the heating mode H, and the standby mode D according to the storage chamber temperature sensed by the temperature sensor. The cooling mode E is not limited to that the storage chamber W is continuously cooled by the cooling device and may include a case where the storage chamber is cooled by the cooling device as a whole, but the storage chamber W is temporarily not cooled by the cooling device and a case where the storage chamber W is cooled by the cooling device as a whole, but the storage chamber is temporarily heated by the heating device. The cooling operation E may include a case where the time when the storage chamber is cooled by the cooling device is longer than the time when the storage chamber W is not cooled by the cooling device.

The heating mode H is not limited to the storage chamber W being continuously heated by the heating device and may include a case where the storage chamber W is heated by the heating device as a whole, but the storage chamber W is temporarily not heated by the heating device and a case where the storage chamber W is heated by the heating device as a whole, but the storage chamber W is temporarily cooled by the cooling device. The heating operation H may include a case where the time when the storage chamber W is heated by the heating device is longer than the time when the storage chamber W is not heated by the heating device.

There is a case where the temperature of the storage chamber W, which has been temperature-controlled by the cooling mode E, may be kept below a target temperature lower limit value without lifting above the target temperature lower limit value for a long time in a state of being lowered below the target temperature lower limit value. In this case, the refrigerator may start the heating mode H so that the storage chamber W is not overcooled when the storage chamber temperature falls below the lower limit temperature, and the heating device can be turned on. The lower limit temperature may be a temperature set to be lower than the target temperature lower limit value by the predetermined amount.

The refrigerator may then start the heating mode H so that the storage chamber temperature is not maintained in a low state for a long time when the storage chamber temperature is maintained between the target temperature lower limit value and the lower limit temperature during the setting time.

The heating mode H may be started when the storage temperature is at the lower limit temperature, and the lower limit temperature may be the heating mode start temperature. One example of the standby mode D may be a mode in which the storage chamber temperature is maintained between the target lower limit value and the lower limit temperature, the refrigerator may be controlled in the order of the cooling mode E, the standby mode D, and the heating mode H without immediately switching to the heating mode H during the cooling mode E.

The temperature of the storage chamber W, which has been temperature-controlled by the heating mode H, may be kept above the target temperature upper limit value without being lowered below the target temperature upper limit value for a long time in a state of lifting above the target temperature upper limit value. In this case, when the storage chamber temperature exceeds the upper limit temperature, the refrigerator can start the cooling mode E so that the storage chamber W is not overheated, and the cooling device can be turned on. The upper limit temperature may be a temperature set to be higher than a target temperature upper limit value.

The refrigerator may start the cooling mode E so that the storage chamber temperature does not remain high for a long time when the storage chamber temperature is maintained between the target temperature upper limit value and the upper limit temperature during the setting time. The cooling mode E may be started if the storage temperature is the upper limit temperature, and the upper limit temperature may be the cooling mode start temperature.

Another example of the standby mode D may be a mode in which the storage chamber temperature is maintained between the target temperature upper limit value and the upper limit temperature, and without switching to the cooling mode E immediately during the heating mode H, the refrigerator may be controlled in the order of the heating mode H, the standby mode D, and the cooling mode E. For example, the cooling mode E may be a mode in which the refrigerant passes through the evaporator, the air in the storage chamber W is cooled by the evaporator, and then flows into the storage chamber W.

In the cooling mode E, the compressor may be turned on or off according to the temperature of the storage chamber W. In the cooling mode E, the compressor may be turned on or off such that the storage chamber temperature is maintained between the target temperature upper limit value and the target temperature lower limit value. Specifically, the compressor may be turned on because the cooling is not satisfied when the storage chamber temperature reaches the target temperature upper limit value and may be turned off when cooling is satisfied when the storage chamber temperature reaches the target temperature lower limit value.

For example, in the heating mode H, the heater may be turned on or off so that the storage chamber temperature is maintained between the target temperature upper limit value and the target temperature lower limit value. Specifically, the heater may be turned off because heating is satisfied when the storage chamber temperature reaches the target temperature upper limit value and may be turned on because heating is not satisfied when the storage chamber temperature reaches the target temperature lower limit value.

For example, the standby mode D may be a mode in which the refrigerant does not pass through the evaporator and the heater maintains the off state. The standby mode D may be a mode in which air in the storage chamber W is not forced to flow by the storage chamber fan. The standby mode D may be a mode in which the heater also maintains the off state while the compressor maintains the off state.

The plurality of modes may further include a humidification mode for increasing the humidity of the storage chamber. The humidification mode may be a mode in which air in the storage chamber W may be humidified by flowing into the cooling device chamber by a fan, and the humidified air may flow into the storage chamber W to humidify the storage chamber, in a state where at least a portion of the cooling device is in an off state (for example, the supply of refrigerant to the evaporator is interrupted, the thermoelectric element is turned off), and at least some of the heating device is maintained in an off state (for example, the heater is turned off and the thermoelectric element is turned off).

For example, the humidification mode may be a mode in which the air in the storage chamber flows to the evaporator by a fan to humidify, and the humidified air flows into the storage chamber to humidify the storage chamber, in a state where the heater maintains in an off state while the refrigerant does not pass through the evaporator. In the humidification mode, a fan that circulates air in the storage chamber to the evaporator and the storage chamber may be driven.

If the device for activating or deactivating the see-through door is defined as a transparency control module, for example, the panel assembly <NUM> and a light source <NUM> may be used. As an example in which the see-through door is activated or deactivated, there may be a case where the transparency of the see-through door itself may vary. For example, the see-through door may maintain in an opaque state when no current is applied to the panel assembly <NUM> and may be changed to be transparent when current is applied to the panel assembly <NUM>. In another example, when the light source <NUM> installed inside the see-through door is turned on, the user may see the storage chamber through the see-through door by the light emitted from the light source <NUM>.

The light source <NUM> may make the panel assembly <NUM> appear transparent or translucent so that an inside of the refrigerator (a side of the storage chamber relative to the panel assembly) looks brighter than outside of the refrigerator (outside relative to the panel assembly). The light source <NUM> may be mounted on the light source mounting portion formed on the cabinet <NUM> or the light source mounting portion formed on the door and may be disposed to emit light toward the panel assembly <NUM>.

In a case where goods having a large quality change due to temperature change are mainly stored in the storage chamber W, the storage chamber W may be opened and closed as short as possible, the number of opening and closing actions is preferably minimized, and the see-through door may open and close the storage chamber W. For example, the see-through door may be provided in the door for opening and closing at least one of the specific goods storage chamber, the constant temperature chamber, and the priority storage chamber.

Referring to <FIG>, in the refrigerator, a door opening and closing the storage chamber may be an automatic door, and the door for opening and closing the specific goods storage chamber, the constant temperature chamber, and a priority storage chamber may be an automatic door.

The controller <NUM> may determine whether the push member <NUM> has reached the door opening position in a process of rotating in the first direction of the drive motor <NUM>. For example, the controller may determine that the push member <NUM> has reached the door opening position when the cumulative rotational speed of the drive motor <NUM> reaches a reference rotational speed. The controller <NUM> may stop the rotation of the drive motor <NUM> when it is determined that the push member <NUM> has moved to the door opening position.

In a state where the door <NUM> is rotated through a predetermined angle, the user may manually increase the opening angle of the door <NUM>. When the user increases the opening angle of the door in a state where the push member <NUM> moves the door <NUM> to the door opening position, the door sensor including a magnet <NUM> and a reed switch <NUM> may sense the manual opening of the door <NUM>, and if the manual opening of the door <NUM> is sensed by the door sensor, the controller <NUM> may output a return signal to the drive motor <NUM>.

The controller <NUM> may transmit the return signal to the drive motor <NUM> so that the push member <NUM> returns to the initial position and the drive motor <NUM> may be reversely rotated in a second direction opposite to the first direction.

When the power of the refrigerator is turned on, the controller <NUM> may wait to receive an opening command of the door <NUM>. When the door opening command is input through the input device, the controller <NUM> may transmit an opening signal to the drive motor <NUM>.

The drive motor <NUM> may be rotated in the first direction by the controller <NUM> when an opening signal is input, and the pinion <NUM> and the rack <NUM> may transmit the rotational force of the drive motor <NUM> to the drawer body <NUM>, the drawer body 6A may advance the door body 6B while advancing forward in the storage chamber, and the door body 6B may be advanced to be spaced apart from the cabinet <NUM> toward the front of the cabinet <NUM>.

When the drawer body 6A is advanced as described above, the upper surface of the drawer body 6A may be exposed. In a state where the drawer body 6A is advanced to the opening position, the user may enter a door closing command such that the drawer body 6A retracts to the closing position via the input device.

A refrigerator according to an embodiment of the present disclosure may include a cabinet configured to be formed with a storage chamber, an inner guide configured to partition the storage chamber into a storage space and an air flow path, a partition member configured to partition the storage space into a first space and a second space, a temperature adjusting device configured to be disposed in the air flow path, and a first damper configured to be disposed in the air flow path to adjust air supplied to the first space. The upper height of the temperature adjusting device may be lower than the lower height of the partition member.

If the upper height of the temperature adjusting device is higher than the height of the partition member, the portion of the inner guide facing the temperature adjusting device and the first space may be increased, and the first space may be reduced in volume. On the other hand, if the upper height of the temperature adjusting device is lower than the lower height of the partition member, the portion of the inner guide facing the first space and the temperature adjusting device may be minimized or absent, and the volume of the first space may be maximized.

The first damper is provided at a height overlapping the partition member in a horizontal direction. If the first damper is arranged in a region of the inner guide facing the first space, the thickness of the portion of the inner guide facing the first space may be thick in consideration of the first damper, and in this case, the volume of the first space may be decreased. On the other hand, if the first damper is disposed at a height overlapping the partition member, it may not be necessary to form a thickness of the portion of the inner guide facing the first space thicker than the first damper, and the volume of the first space may be maximized.

The refrigerator may further include a fan configured to overlap the temperature adjusting device in a vertical direction. At least a portion of the first damper may overlap the fan in a left and right direction. At least a portion of the first damper may overlap the temperature adjusting device in the vertical direction.

The width of the inner cover in the front and rear direction may be larger than the width of the temperature adjusting device in the front and rear direction, and the width of the discharge guide in the front and rear direction may be smaller than the width of the temperature adjusting device in the front and rear direction. The inner guide may include a suction port through which air of the first space is suctioned. At least a portion of the suction port may face a rear end of the partition member in the front and rear direction and may be spaced apart from the partition member.

The return duct may include an overlap portion which overlaps the fan in the front and rear direction. The return duct may include an expansion portion under the overlap portion in which a width in the left and right direction is expanded toward the outlet portion.

According to this invention, the upper end height of the evaporator may be lower than the lower end height of the partition member, the first damper may be provided at a position overlapping the partition member in the front and rear direction and thus the volume of the storage space may be maximized. In addition, since the protrusion portion that protrudes forward than the other portion of the inner guide may be minimized, the outer appearance of the inner guide may be simplified, and the refrigerator may be advanced when the inner guide has a lot of protruding portions forward.

In addition, the temperature of each of the first space and the second space partitioned by the partition member may be independently controlled using one temperature adjusting device, one fan, and two dampers. In addition, the fan and the first damper may overlap the temperature adjusting device in the vertical direction, so that the maximum width of the inner guide in the front and rear direction may be minimized, and thus the width of the second space in the front and rear direction may be maximized compared to a case where the fan and the first damper are overlapped the temperature adjusting device in the front and rear direction.

In addition, a portion of at least one of the first damper and the second damper may overlap the fan in the left and right direction, so that the height difference between the first damper and the second damper is not large, and each of the first damper and the second damper may be located as close as possible to the fan. In this case, the length of the inner guide in the vertical direction may be shorter than that in a case where the height difference between the first damper and the second damper is large. In addition, the first damper may be provided eccentrically to one side of the left and right of the air flow path, the second damper may be provided eccentrically to the other side of the left and right of the air flow path, so that the air blown from the fan may flow quickly into each of the first damper and second damper.
