SUBSTANCE: humidifier comprises a housing comprising a chamber; a water tank designed to supply water to the chamber; airflow-creating means for creating an airflow over the water in the chamber; humidifying agents for moistening the airflow with the water from the chamber; a cartridge detachably mountable in the housing. The cartridge comprises a lamp emitting ultraviolet radiation to irradiate the water in the chamber. The chamber comprises a tube transparent to ultraviolet rays, designed for placing a lamp in it; and an outlet for air to eject the airflow; the housing comprising a plurality of supports for supporting a cartridge therebetween, each of the supports comprising a curved track for guiding the cartridge movement in the direction of the tube. The tracks are shaped so that as the cartridge moves in the direction of the tube, it is oriented for installing the lamp into the tube.
EFFECT: invention makes it possible to replace the lamp in such a way as to minimize the possibility of damaging a new lamp when it is placed in the device housing.
The present invention relates to a fan assembly. In one preferred embodiment, the present invention provides a humidifying device for generating a humid air stream and an air stream for dispersing humid air inside a living room such as a room, office, or the like.
A household humidification device is generally made in the form of a portable device having a casing containing a water tank in which a certain volume of water is located, and a fan to create a stream of air passing through the casing duct. The stored water flows, usually by gravity, into an aerosol spray device to create water droplets from the incoming water. This device can be made in the form of a heater or a high-frequency vibrating device, such as a converter. Drops of water fall into the stream of air passing through the duct, as a result of which moisture is released into the surrounding space. The device may include a sensor for measuring relative humidity in the surrounding area. The sensor gives a signal with information about the measured relative humidity to the drive circuit, which controls the converter to maintain the relative humidity in the surrounding area at about the required level. Normally, the transmitter will turn off after the measured relative humidity level is about 5% higher than the desired level, and re-turned on after the measured relative humidity level is about 5% lower than the required level.
It is known to use an ultraviolet (UV) lamp or other source of UV radiation to disinfect water supplied to an aerosol spray device. For example, US Pat. No. 5,859,952 describes a humidifier in which water supplied from a tank passes through a disinfection chamber before it is supplied through a tube to a chamber in which there is an ultrasonic aerosol dispenser. In the disinfection chamber there is a window transparent for UV rays, from the bottom of which there is a UV lamp for irradiating water passing through the disinfection chamber.
US 7,540,474 describes a humidifier in which a water tank includes a UV-transparent tube for supplying water to the outlet of the tank, and a main body on which the tank is mounted includes a UV lamp that irradiates water, according to as it passes through the tube to the outlet.
The present invention provides a humidification device, comprising: a housing comprising a chamber;
means for creating an air stream to create an air stream above the water in the chamber;
humidification means for humidifying the air flow with water from the chamber;
a cartridge removably mounted in the housing, the cartridge comprising a lamp emitting ultraviolet radiation for irradiating water in the chamber, the chamber comprising a tube transparent to UV rays, intended to be placed in the lamp; and
at least one air outlet for discharging air flow;
however, the housing contains many supports, between which, resting on them, a cartridge is installed, each of the supports contains a curved track for the direction of movement of the cartridge in the direction of the tube, the tracks are shaped so that as the cartridge moves in the direction of the tube, the tracks orient the cartridge to install the lamp into the tube.
Periodically, the UV lamp may require replacement, for example, due to burnout of the bulb in the lamp. The present invention allows the replacement of the lamp in such a way as to minimize the likelihood of damage to a new lamp when it is placed in the housing of the device. Due to the presence of curved tracks for directing the cartridge with the lamp in it toward the tube, the user can slide the cartridge along the tracks by sliding, and the shape of the tracks helps align the cartridge with the tube, minimizing contact between the lamp and the tube when placing the lamp in the receiver. Any distortion between the lamp and the tube will immediately be noticeable to the user due to the need to apply increased force when pushing the cartridge along the tracks, which will allow the user to quickly eliminate the distortion before the lamp is damaged.
The shape of the supports also allows you to place an opening through which the cartridge is inserted into the housing, convenient for both the user and the manufacturer. For example, instead of placing a similar opening directly in line with the tube hole, for example, on the side wall of the housing, the opening can be placed on the bottom of the housing, while the supports are bent so that they change the direction of movement of the cartridge relative to the supports when it is installed in case, for example, at least 90 °. This allows you to close the opening with a panel so that it is not noticeable while using the device.
As noted above, the cartridge can preferably slide along the tracks. Preferably, the cartridge comprises a plurality of support elements, each of which support elements may be included in a respective track. The support elements preferably have a non-ring shape and preferably have a 2-fold axial symmetry, so that the width of each support element is preferably less than its height.
The width of each track preferably varies along the length of the track, and is preferably configured so that the width of the track increases along the length of the track. In one preferred embodiment, the width of each track is increased from a first width that is substantially equal to the width of its corresponding cartridge support member to a second width that is substantially equal to the length of its corresponding cartridge cartridge support. Such narrowing of the width of the track at its beginning can help the user to insert the cartridge between the supports in the correct position. As the cartridge moves along the track, as a result of increasing the width of each track, the cartridge rotates 90 ° relative to the track as it moves along the track. The curvature of the supports allows the cartridge to be held in a substantially constant axial alignment between the tube and the lamp as the cartridge moves along the curved portion of the support, which, in turn, minimizes the internal volume needed to accommodate the cartridge as it is pushed toward the tube.
The housing preferably has a bottom defining an opening through which the cartridge can be inserted into the housing. Each of the supports is preferably connected, and preferably integrally molded, to the bottom of the housing. Each track preferably extends from the bottom of the housing towards the camera. The longitudinal axis of the tube is preferably substantially parallel to the bottom of the housing.
The housing preferably comprises a panel for closing the opening, the panel preferably comprising means for pushing the cartridge into a position where the lamp is fully inserted into the tube. In one preferred embodiment, the panel preferably comprises at least one rib extending from it to engage the cartridge and push it inside the tube when the panel is returned to the closed position on the housing.
The wetting means preferably comprise a converter, which, if necessary, can be removed from the housing through an opening, for replacement or cleaning.

In FIG. Figure 1-3 shows the outside views of the fan assembly. In this example, the fan assembly is made in the form of a humidifier 10. In general, the humidifier 10 comprises a housing 12 containing an air inlet through which air enters the humidifier 10, and a nozzle 14 in the form of an annular shell that is mounted on the housing 12 and in which there are several air outlets for discharging air from the humidification device 10.
The nozzle 14 is configured to eject two different air currents. The nozzle 14 comprises a rear section 16 and a front section 18 connected to the rear section 16. Each of the sections 16, 18 has an annular shape and passes around the channel 20 of the nozzle 14. The channel 20 passes through the center of the nozzle 14 so that the center of each of the sections 16 , 18 is located on the X axis of channel 20.
In this example, each of the sections 16, 18 has the shape of a “treadmill” in the sense that each of the sections 16, 18 contains two generally straight sections located on opposite sides of the channel 20, a curved upper section connecting the upper ends straight sections, and a curved lower section connecting the lower ends of the straight sections. Meanwhile, sections 16, 18 may be of any shape, for example sections 16, 18 may be round or oval. In this embodiment, the height of the nozzle 14 is greater than the width of the nozzle, however, the nozzle 14 can be designed so that the width of the nozzle 14 is greater than the height of the nozzle 14.
Each of the sections 16, 18 of the nozzle 14 determines the path along which the corresponding one of the air flows. In this embodiment, the rear section 16 of the nozzle 14 defines a first air flow path through which the first air flow passes through the nozzle 14, and the front section 18 of the nozzle 14 defines a second air flow path through which the second air flow passes through the nozzle 14.
As shown in FIG. 4, 5 (a) and 5 (b), the rear section 16 of the nozzle 14 comprises an annular outer shell portion 22 extending around and connected to the annular inner shell portion 24. Each of the parts 22, 24 of the shell passes around the axis X of the channel. Each part of the shell may consist of several connected parts, however, in this embodiment, each of the parts 22, 24 of the shell is made in the form of a single molded part. Each of the parts 22, 24 is preferably made of plastic. As shown in FIG. 5 (b), the front of the inner part 24 of the shell has an annular outer wall 24a that extends generally parallel to the channel axis X, a front end wall 24b and an annular intermediate wall 24c that extends generally perpendicular to the channel axis X and which connects the outer wall 24a to the end wall 24b so that the end wall 24b protrudes forward beyond the intermediate wall 24c. When assembling, the outer surface of the outer wall 24a is connected to the inner surface of the front end of the outer part 22 of the shell, for example, using adhesive.
The outer shell part 22 includes a tubular base 26 that defines a first air inlet 28 for the nozzle 14. The outer shell part 22 and the inner shell part 24 together define the first air outlet 30 for the nozzle 14. As will be discussed in more detail below, the first air stream enters the nozzle 14 through the first air inlet 28 and is ejected through the first air outlet 30. The first air outlet 30 is determined by overlapping or opposite sections of the inner surface 32 of the outer shell part 22 and the outer surface 34 of the inner shell part 24. The first air outlet 30 is in the form of a gap. The slot has a relatively constant width in the range of 0.5 to 5 mm. In this example, the first air outlet has a width of about 1 mm. Around the first air outlet 30, at intervals, spacers 36 may be provided that extend laterally the overlapping portions of the outer shell portion 22 and the inner shell portion 24 to adjust the width of the first air outlet 30. These spacers can be molded from any of the shell parts 22, 24.
In this embodiment, the first air outlet 30 partially extends around the channel 20. The first air outlet 30 extends along the curved upper portion and the straight portion of the nozzle 14. Meanwhile, the first air outlet 30 can extend completely around the channel 20. As can be seen from FIG. . 9, the nozzle 14 includes a sealing element 38 that prevents the first airflow from escaping from the curved lower portion of the nozzle 14. In this embodiment, the sealing element 38 is generally U-shaped and is held by a recess formed at the rear end of the inner portion 24 the shell so that it is in a plane substantially perpendicular to the X axis. The sealing element 38 engages with a U-shaped protrusion 39 extending forward from the rear end of the curved lower portion of the outer shell portion 22 , Forming a seal with it.
The first air outlet 30 is configured to discharge air through the front of the channel 20 of the nozzle 14. The shape of the first air outlet 30 allows air to be directed along the outer surface of the nozzle 14. According to this embodiment, the outer surface 34 of the inner part 24 of the shell comprises a Coanda surface 40, over which is the first air outlet 30, configured to direct the first air flow. Coanda surface 40 is ring-shaped and therefore runs continuously around the central axis X. The outer surface 34 of the inner portion 24 of the shell also includes a diffuser portion 42 that converges to a cone as it moves away from the X axis, in the direction from the first exit 30 to the front end face 44 of the nozzle 14.
Parts 22, 24 of the casing together define an annular first inner passage 46 for supplying a first air flow from the first air inlet 28 to the first air outlet 30. The first inner passage 46 is determined by the inner surface of the outer shell part 22 and the inner surface of the inner shell part 24. The tapering annular mouth 48 of the rear section 16 of the nozzle 14 directs the first air flow to the first air outlet 30. Therefore, we can assume that the path of the first air stream passing through the nozzle 14 is formed by the first air inlet 28, the first internal passage 46, the mouth 48 and the first air outlet 30.
The front section 18 of the nozzle 14 contains an annular front portion 50 of the shell. The front part 50 of the shell extends around the axis X of the channel and has a treadmill shape similar to the shape of the other parts 22, 24 of the shell of the nozzle 14. Like the parts 22, 24 of the shell, the front part 50 of the shell can consist of many connected parts, however, In this embodiment, the front shell portion 50 consists of a single molded part. The front part 50 of the shell is preferably made of plastic.
The front portion 50 of the shell comprises an annular outer wall 50a that extends generally parallel to the channel axis X, an annular inner wall and an annular front wall 50b that connects the outer side wall 50a to the inner wall. The inner wall comprises a front portion 50c that extends generally parallel to the front wall 24b of the inner shell portion 24, and a rear portion 50d angled to the front portion 50c so that the rear portion 50d tapers in a cone in the X-axis direction, from the first air outlet 30 to the front end 44 of the nozzle 14. During assembly, the front part 50 of the shell is attached to the inner part 24 of the shell, for example, by snapping the outer side wall 50a of the front part 50 of the shell to the outer ring-shaped wall 24a of the inner portion 24 of the shell.
The lower end of the front portion 50 of the shell contains a tubular base 56.
The base 56 defines a plurality of second air inlets 58 for the nozzle 14. In this embodiment, the base 56 comprises two second air inlets 58. Alternatively, base 56 may comprise a single air inlet 58. The front shell portion 50, together with the inner shell portion 24, defines a second air outlet 60 for the nozzle 14. In this example, the second air outlet 60 extends partially around the channel 20, along the curved upper portion and straight sections of the nozzle 14. Alternatively, the second outlet 60 for air can pass completely around the channel 20. The second outlet 60 for air is made in the form of a gap having a relatively constant width in the range from 0.5 to 5 mm. In this example, the second air outlet 60 has a width of about 1 mm. A second air outlet 60 is located between the inner surface of the end wall 24b of the inner shell part 24 and the outer surface of the rear portion 50d of the inner wall of the front shell part 50. Around the second air outlet 60, at intervals, spacers 62 may be arranged to push apart the overlapping portions of the inner shell 24 and the front shell 50 to adjust the width of the second air outlet 60. These spacers can be molded from any of the shell parts 22, 50.
The second air outlet 60 is configured to discharge a second air stream over the outer surface of the rear portion 50d of the inner wall of the front portion 50 of the shell. Said surface is thus a Coanda surface, on top of which each of the second air outlets 60 can direct a corresponding part of the second air stream. The Coanda surface also continuously extends around the X axis, however, since the air outlet 60 extends only around a portion of the channel 20, this Coanda surface can also extend only around a portion of the channel 20. The outer surface of the front portion 50c of the front portion 50 of the shell creates a diffuser portion that converges on the cone as you move away from the X axis, from the second air outlet 60 to the front end 44 of the nozzle 14.
Parts 24, 50 of the casing together define an annular second inner passage 68 for supplying a second air stream from the second air inlets 58 to the second air outlet 60. The second inner passage 68 is defined by the inner surfaces of the inner part 24 of the shell and the front part 50 of the shell. Therefore, it can be considered that the second air flow path passing through the nozzle 14 is formed by second air inlets 58, an internal passage 68 and a second air outlet 60.
Returning to FIG. 1-3, the housing 12, in General, has a cylindrical shape. The housing 12 comprises a base 70. In FIG. 6 and 7 show external views of the base 70. At the base 70 there is a peripheral outer wall 72, which has a cylindrical shape and contains an air inlet 74. In this example, the air inlet 74 consists of a plurality of holes made in the outer wall 72 of the base 70. The user interface of the humidifier 10 may be located on the front portion of the base 70. The user interface is shown schematically in FIG. 16 and will be discussed in more detail below, while the user interface includes at least one switch or button 75. A power cable (not shown) for supplying power to the humidifier 10 passes through an opening in the base 70.
As shown in FIG. 9, the base 70 comprises a first air passage 76 for supplying a first air flow to a first air flow path passing through a nozzle 14, and a second air passage 78 for supplying a second air flow to a second air flow path passing through a nozzle 14. First air passage 76 passes through the base 70 from the air inlet 74 to the first air inlet 28 of the nozzle 14. The base 70 comprises a bottom 80 connected to the lower edge of the outer wall 72. On the upper surface of the bottom 80 is a sheet 81 of sound-absorbing foam . A tubular central wall 82 having a smaller diameter than the outer wall 72 is connected to the outer wall 72 by an arcuate support wall 84. The central wall 82 is substantially coaxial with the outer wall 72. The support wall 84 is located above and generally parallel to the bottom 80 The support wall 84 extends partially around the central wall 82, defining an opening for access to the water tank 140 at the base 70, as will be discussed in more detail below. The central wall 82 extends upward from the support wall 84. In this example, the outer wall 72, the central wall 82 and the support wall 84 are made as a single component of the base 70, however, as an option, this component of the base 70 can be formed from two or more of these walls . The upper wall of the base 70 is connected to the upper edge of the central wall 82. The upper wall has a lower truncated-conical section 86 and an upper cylindrical section 88 into which the base 26 of the nozzle 14 is inserted.
A central wall 82 extends around the impeller 90 to create a first air flow through the first air passage 76. In this example, the impeller 90 is in the form of a mixed flow impeller. The impeller 90 is connected to a rotating shaft exiting the motor 92, driving the impeller 90. In this embodiment, the motor 92 is a brushless DC motor whose variable speed is controlled by the drive circuit 94, depending on the speed selected by the user. Drive circuit 94 of FIG. 16 is shown as a single component, however, the drive circuit 94 may consist of several physically separate, but electrically connected, sub-loops, each of which contains a corresponding processor controlling various components or functions of the humidification device 10. The maximum rotation speed of the electric motor 92 is preferably 5000 to 10000 rpm The electric motor 92 is located inside the engine compartment, consisting of a domed upper part 96 connected to the lower part 98. A set of guide vanes 100 is connected to the upper surface of the upper part 96 of the engine compartment, directing air toward the first air inlet 28 for the nozzle air 14.
The engine compartment is located inside, in General, truncated-conical casing 104 of the impeller and mounted on it. The impeller casing 104, in turn, is mounted on an annular platform 106 extending inward from the central wall 82. The annular inlet element 108 is connected to the bottom of the impeller casing 104 to direct air flow into the impeller casing 104. Between the impeller casing 104 and the platform 106, there is an annular sealing element 110, which does not allow air to pass around the outer surface of the impeller casing 104 to the input element 108. The platform 106 preferably comprises a guide portion for guiding the power cord from the drive circuit 94 to the motor 92.
The first air passage 76 extends from the air inlet 74 to the inlet 108. From the inlet 108, the first air passage 76, respectively, passes through the impeller casing 104, the upper edge of the central wall 82 and the portions 86, 88 of the upper wall.
The second air passage 78 is configured to receive air from the first air passage 76. The second air passage 78 is adjacent to the first air passage 76. The second air passage 78 contains an air duct 110 into which air from the first air passage 76 enters. The air duct 110 is defined by a central wall 82 the base 70. The duct 110 is adjacent and, in this example, is radially outside the part of the first air passage 76. In the duct 110, upstream of the guide vanes 100, there is an inlet port 112, which is received part of the air flow ejected by the guide vanes 100, and forms a second air flow. In the duct 110 there is an exhaust port 114 located in the Central wall 82 of the base 70.
The humidifier 10 is configured to increase the humidity of the second air stream before it enters the nozzle 14. As shown in FIG. 1, 2 and 8 (a) -10 (b), the humidifier 10 comprises a water tank 120, schematically mounted on the base 70 of the housing 12. The water tank 120 has a cylindrical outer wall 122, which has the same radius as and the outer wall 72 of the base 70 of the housing 12, so that the housing 12 visually has a cylindrical shape after installing the water tank 120 on the base 70. The water tank 120 has a tubular inner wall 124 that surrounds the walls 82, 86, 88 of the base 70 after installing the tank 120 for water to the base 70. Outer wall 122 and inner wall 124 predelyayut, together with the annular top wall 126 and annular bottom wall 128 of the tank 120 for water, an annular volume for storing water. The water tank 120 thus surrounds the impeller 90 and the motor 92 and at least a portion of the first air passage 76 after the water tank 120 is installed on the base 70. After installing the water tank 120 on the base 70, the bottom wall 128 of the tank 120 for water engages with the support wall 84 of the base 70 and rests on the support wall 84 of the base 70. On the bottom wall 128, protrusions 130 included in the recesses 132 formed on the support wall 84 of the base 70 can be formed to ensure the exact angular position of the tank 120 for water on the basis of 70. The protrusions 130 can be made in the form of magnets that interact with other magnets (not shown) located below the recesses 132 on the lower surface of the support wall 84, helping to accurately determine the position of the water tank 120 on the base 70 and increasing the force required to move the water tank 120 relative to the base 70. This reduces the likelihood of accidentally displacing the water tank 120 relative to the base 70.
The capacity of the water tank 120 is preferably from 2 to 4 liters. In particular, as shown in FIG. 8 (a) and 8 (b), the drain member 134 is detachably connected to the bottom wall 128 of the water tank 120, for example, using mating threaded connections. In this example, the water tank 120 is filled by removing the water tank 120 from the base 70 and turning the water tank 120 so that the drain member 134 is lifted up. Then, the drain member 134 is unscrewed from the water tank 120, and water is poured into the water tank 120 through an opening formed after disconnecting the drain member 134 from the water tank 120. The drain element 134 preferably contains several radial ribs that facilitate hand grip and rotation of the drain element 134 relative to the water tank 120. After filling the water tank 120, the user reconnects the drain element 134 to the water tank 120, returns the water tank 120 to the inverted position, and sets the water tank 120 on the base 70 again. Inside the drain element 134 there is a spring-loaded valve 136 preventing water leakage. through the water outlet in the drain member 134 after returning the water tank 120 to the non-reversed position. The valve 136 is deflected to a position where the skirt of the valve 136 engages with the upper surface of the drain member 134, preventing water from entering the drain member 134 from the water tank 120.
The upper wall 126 of the water tank 120 contains one or more supports 138, by which the inverted water tank 120 rests on a work surface, countertop, or other supporting surface. In this example, two parallel supports 138 are formed in the peripheral part of the upper wall 126, on which the inverted water tank 120 rests.
As shown in FIG. 6, 7 and 9-10 (b), the base 70 comprises a water tank 140 into which water enters from the water tank 120. The water tank 140 is a separate component that is installed on the bottom 80 of the base 70 and is accessed through an opening formed in the support wall 84 of the base 70. The water tank 140 comprises an inlet chamber 142 into which water flows from the water tank 120, and an outlet chamber 144 into which water enters from the inlet chamber 142 and into which water is sprayed, being carried along with the second air stream. An inlet chamber 142 is located on one side of the water tank 140, and an outlet chamber 144 is located on the other side of the water tank 140. The water tank 140 comprises a base 146 and a side wall 148 extending around and rising upward around the circumference of the base 146. The base 146 is shaped so that the depth of the outlet chamber 144 is greater than the depth of the inlet chamber 142. The sections of the base 146 located inside each of the chambers 142 , 146, are preferably substantially parallel and preferably parallel to the bottom 80 of the base 70, so that these sections of the base 146 extend substantially horizontally after the humidifier 10 is horizontal second supporting surface. A channel 150 formed in the water tank 140 allows water to pass from the inlet chamber 142 to the outlet chamber 144.
The pin 152 extends upward from the base section 146, partially forming the inlet chamber 142. After installing the water tank 120 on the base 70, the pin 152 enters the drain element 134, pushing the valve 136 up and opening the drain element 134, thereby allowing water to act forces of gravity enter the inlet chamber 142. As the inlet chamber 142 is filled with water, water passes through the channel 150 and enters the outlet chamber 144. As the water exits the water tank 120, it is replaced by air that enters the water tank 120 through the slots 154 on the side wall Foot member 134. As the filling chambers 142, 144 with water, the water level in the chambers 142, 144 aligned. The drain element 134 is designed so that the water tank 140 can be filled with water to a maximum level that is substantially coplanar with the upper edges of the slots 154 located in the side wall of the drain element 134; above this level, air cannot flow from the water tank 120 when replacing water flowing from the water tank 120.
The base section 146, partially forming the exhaust chamber 144, contains an annular opening for access to the piezoelectric transducer 156. The drive circuit 94 may cause the transducer 156 to vibrate in an aerosol spray mode to spray water in the exhaust chamber 144. In the aerosol spray mode, the transducer 156 can create supersonic oscillations with frequency
, which may be in the range of 1 to 2 MHz. The transducer 156 is part of the piezoelectric transducer assembly that is connected to the bottom side of the bottom 80 of the base so that it protrudes through the opening 157 of FIG. 14 formed at the bottom 80 of the base 70.
The water tank 140 also includes an ultraviolet (UV) radiation source for irradiating the water contained in the water tank 140. In this embodiment, the UV radiation source is configured to irradiate water located within the outlet chamber 144 of the water tank 140. In this embodiment, the UV radiation source comprises a UV lamp 160, which is part of the UV lamp assembly 162 at the base 70. The UV lamp assembly 162 is shown in FIG. 11 (a) -11 (d). The UV lamp assembly 162 is configured as a cartridge that can be removably inserted into the base 70 so that, if necessary, the user can replace the UV lamp assembly 162. UV lamp assembly 162 comprises a body section 164 and a rod section 166 extending from the body section 164. The rod section 166 has a concave cross section and extends partially above the UV lamp 160. The concave surface of the rod section 166 may be made or may have a coating made of reflective material for reflecting UV radiation emitted by the UV lamp 160 towards the exhaust chamber 144 of the water tank 140. In this embodiment, a cover 168 is arranged around the housing section 164 to form elements that allow the UV lamp assembly 162 to rest on the base 70. Although in this embodiment, the cover 168 is a separate component that connects to the housing section 164 during assembly, for example, by means of a snap-on connection, as an option, the elements of the cover 168 can be located on the body section of the node 162 of the UV lamp. The bundle 170 connects the UV lamp 160 to the connector 172 for connecting the UV lamp to the drive circuit 94. The protective caps 174, 176, worn on the opposite ends of the UV lamp, close the electrical contacts between the UV lamp 160 and the bundle 170, and also serve as UV lamp support 160 inside the UV lamp assembly 162.
As shown in FIG. 6, 7 and 13-15 (c), the water tank 140 comprises a tube 178 transparent to UV rays. The tube 178 is located inside the outlet chamber 144 of the water tank 140. As will be discussed in more detail below, the UV lamp assembly 162 is supported on the base 70 so that the UV lamp 160 is located inside the tube 178 after it is fully inserted into the base 70. Preferably, the open end of the tube 178 protrudes from the opening formed in the side the wall 148 of the water tank 140, allowing the UV lamp 160 to enter the tube 178. An annular sealing element can be installed between the tube 178 and the opening formed in the side wall 148 to prevent water from leaking through the opening.
The base 70 contains two supports 180, on which the UV lamp assembly 162 rests within the base 70. The supports 180 are connected and preferably integrally formed with the bottom 80 of the base 70. The supports 180 are parallel and located on each side of the opening 182 through which the UV assembly 162 the lamp is inserted and removed from the base 70. The opening 182 is typically closed by a panel 184 removably connected to the bottom side of the bottom 80 of the base 70. Lowering the panel 184, or separating the panel 184 from the bottom 80 of the base 70, as shown in FIG. 12, the user can access both the UV lamp assembly 162 and the piezoelectric transducer assembly to replace or repair each of the components if necessary.
Each of the supports 180 has a curved shape and extends upward from the bottom side of the bottom 80 of the base 70 to the water tank 140. The upper surfaces of the supports 180 are connected by bridges 186, 187, which are also preferably molded with the bottom 80 of the base 70, providing structural strength of the supports 180.
Each of the supports 180 contains a set of curved guides 188 for guiding the movement of the UV lamp assembly 162 when it is installed in the base 70. Each set of guides 188 defines a curved track 190 that extends from the lower surface of the bottom 80 of the base 70 to the free ends of the support 180. Cover 168 the UV lamp assembly 162 comprises a first pair of support members 192, each of which enters the corresponding track 190 when the UV lamp assembly 162 is installed in the base 70 and each of which slides along the corresponding track 190 when the UV lamp assembly 162 is installed in warp 70.
As the UV lamp assembly 162 moves along the paths 190, the shape of the paths 190 allows the UV lamp assembly 162 to be oriented to install the UV lamp 160 in the tube 178. This minimizes contact between the UV lamp 160 and the tube 178 when the UV lamp assembly 162 is installed in a base 70, simplifying the placement of the UV lamp assembly 162 in the base 70 and minimizing the likelihood of damage to the UV lamp 160 when installing the UV lamp assembly 162 in the base 70.
As shown in FIG. 14 and 15 (c), the width of each track 190 varies along the length of the track 190. In this example, the width of each track 190 increases from a first width that is substantially equal to the width of the first support member 192 to a second width that is substantially equal to the length of the first reference element 192. As the first support elements 192 move along the tracks 190, the orientation of the first support elements changes from that in which the first support elements 192 are essentially parallel to the guides 188, to that in which the first support elements 192 are essentially perpendicular guides 188. This minimizes changes in the angle between the UV lamp 160 and the tube 178 when moving the UV lamp assembly 162 along the tracks 190.
To install the UV lamp assembly 162 in the base 70, the viewing panel 184 is first lowered or removed to open the opening 182 through which the UV lamp assembly 162 is inserted into the base 70. After that, the user places the UV lamp assembly 162 as shown in FIG. 15 (a) so that the protective caps 174 are at least partially inside the tube 178 and so that each support member 192 is at the beginning of the corresponding track 190. The user then pushes the bottom surface 194 of the cover 168 towards the bottom 80 of the base 70, as this is shown in FIG. 15 (b) until the second pair of support elements 196 located on the cover 168 engage with the bottom surface of the bottom 80 of the base 70. As a result, the support elements 192, moving along the curved sections of the tracks 190, align the UV lamp 160 with the tube 178. After that, the user, by sliding, moves the cover 168 along the bottom 80 of the base 70, completely inserting the UV lamp 160 inside the tube 178, as shown in FIG. 15 (c). Finally, the user connects the connector 172 of the UV lamp assembly 162 to the drive circuit 94 and puts the panel 184 in place, closing the opening 182. When the panel 184 is put back into place, to the bottom 80, the ribs 198 of the panel 184 engage with the UV lamp assembly 162, pushing UV lamp assembly 162 in the fully inserted position. To remove the UV lamp assembly 162 from the base 70, it is sufficient for the user to perform the above steps in the reverse order.
Returning to FIG. 6, 7 and 9-10 (b), the water tank 140 comprises a deflector 200 for directing water entering the outlet chamber 144 along the tube 178. The deflector 200 extends across the outlet chamber 144 and divides the outlet chamber 144 into an inlet section receiving water from the inlet chamber 142, and the outlet section, inside which water is converted into an aerosol by the transducer 156. The sealing element 202 extends between the deflector 200 and the tube 178. As water enters the outlet chamber 144, the water is guided by the deflector 200 along the upper portion of the tube 178. completed in the sealing member 202, together with the tube 178 defines an opening 204 through which the water enters the outlet section of the outlet chamber 144.
The upper edge of the deflector 200 is located above the maximum water level in the water tank 140. Inside the water tank 140 is a level sensor 206 (shown schematically in FIG. 16) that senses the water level inside the water tank 140. Alternatively, level sensor 206 may reside in water tank 120. The base 70 may also include a proximity sensor 208 that detects the installation of a water tank 120 on the base 70. The proximity sensor 208 may be in the form of a Hall sensor that interacts with a magnet (not shown) located on the bottom wall 128 of the water tank 120 , determining the presence or absence of a tank 120 for water on the basis of 70.
The water tank 120 defines an inlet duct 210 for receiving a second air stream from the outlet port 114. In this embodiment, the inlet duct 210 is defined by a removable section 212 of the water tank 120, which is removably connected to the inner wall 124 of the water tank 120. The inlet duct 210 includes an inlet port 214, which faces the outlet port 114 of the duct 110 in the base 70 after the water tank 120 is installed on the base, and the outlet port 216, which is located above the outlet section of the outlet chamber 114 of the water tank 140. The maximum water level in the water tank 140 is preferably selected so that the outlet port 216 is above a similar maximum water level. As a result, the second air stream enters the water tank 140 directly above the surface of the water located in the outlet chamber 144 of the water tank 140. The removable section 212 of the water tank 120 also defines, together with the inner wall 124 of the water tank 120, an exhaust duct 218 for supplying a second air stream from the water tank 140 to the second air inlets 58 of the nozzle 14. The exhaust duct 218 includes an inlet port 220 adjacent to an outlet port 216 of the inlet duct 212, and two outlet ports 222. In this embodiment, the outlet ports 222 are formed in the upper part 224 of the removable section 212 of the water tank 120. The specified upper part 224 is located inside the deepened part 226 of the upper wall 126 of the tank 120 for water.
As shown in FIG. 9, after the water tank 120 is mounted on the base 70, the inner wall 124 surrounds the upper wall of the base 70 without covering the open upper edge of the upper cylindrical portion 88 of the upper wall. The water tank 120 has a handle 230, which simplifies the removal of the water tank 120 from the base 70. The handle 230 is pivotally connected to the water tank 120 so that it can move relative to the water tank 120 between the folded position, in which the handle 230 is removed inside a recessed section 232 of the upper wall 126 of the water tank 120, and an extended position in which the handle 230 is raised above the upper wall 126 of the water tank 120 so that the user can grab it by hand. In the recessed section 196 of the upper wall 126, there may be one or more resilient elements, such as torsion springs, deflecting the handle 230 to the folded position.
After the nozzle 14 is mounted on the housing 12, the base 26 of the outer portion 22 of the shell of the nozzle 14 is located above the open edge of the upper cylindrical portion 88 of the upper wall of the base 70, and the base 56 of the front portion 50 of the nozzle shell is located above the recessed portion 226 of the upper wall 126 of the tank 120 for water. After that, the user inserts the nozzle 14 in the direction of the housing 12 so that the base 26 fits into the upper cylindrical section 88 of the upper wall of the base 70. After the bases 26, 56 of the nozzle 14 are fully inserted into the housing 12, the first annular sealing element creates an airtight seal between the lower edge of the base 26 and the annular shoulder extending radially inward from the cylindrical portion 88 of the upper wall of the base 70. The elastic corrugated portion 227 of the duct attached to the lower surface of the The upper part 224 of the removable section 212 of the water tank 120 pushes the upper section 224 up towards the nozzle 14, so that an airtight seal is formed between the exhaust duct 218 and the base 56 of the nozzle 14.
There is a mechanism for releasably holding the nozzle 14 on the housing 12. The mechanism is similar to the mechanism described in our pending patent application WO 2013/132218, the contents of which are incorporated herein by reference. Briefly, the housing 12 comprises a button 240, a holding member 242 for engaging the nozzle 14, and an annular actuator 244. After the user presses the button 240, the button 240 exerts a force on the actuator 244 to cause it to rotate, overcoming the biasing force of the spring. Rotating the actuator 244 moves the holding element 242 away from the nozzle 14, allowing the user to lift the nozzle 14 from the housing 12. After the nozzle 14 is lifted from the housing 12, the user can release the button 240. The spring causes the actuator 244 to rotate, returning the holding element 242 back to its holding position.
As noted above, the button 75 for controlling the operation of the humidifier can be located on the outer wall 72 of the base 70 of the housing 12. The button 75 can be used to start and stop the motor 92 to turn the humidifier on and off. In addition, the humidifier 10 includes a remote control 260 for transmitting control signals to the user interface circuit 262 of the humidifier 10. FIG. 16 schematically shows the control system of the humidifier 10, which includes a remote control 260, a user interface circuit 262 and other electrical components of the humidifier 10. In general, the remote control 260 includes a plurality of buttons that can be pressed by a user, and a control unit, generating and transmitting infrared light signals as a result of pressing one of the buttons. Infrared light signals are sent through a window located on one of the ends of the remote control 260. The control unit is powered by a battery located in the battery compartment of the remote control 260.
The first button is used to start and stop the motor 92, and the second button is used to select the speed of the motor 92, and therefore, the rotational speed of the impeller 90. The control system may have a different number of user-defined speed parameters, each of which corresponds to a specific speed of rotation of the motor 92. Third the button is used to select the required level of relative humidity of the room in which the humidifying device 10 is located, for example, a room, an office Do other domestic premises. For example, the required level of relative humidity can be selected in the range from 30 to 80% at a temperature of 20 ° C by repeatedly pressing the third button.
The user interface circuit 262 includes a switch that is actuated after the user presses the button 75, a sensor or receiver 264 for receiving signals transmitted from the remote control 260, and a display 266 displaying the current operating parameters of the humidifier 10.
For example, typically the display 266 shows the currently set relative humidity level. When the user changes the speed of rotation of the motor 92, the display can briefly show the current set speed parameters. Receiver 264 and display 266 may be located directly behind the transparent or light transmitting portion of the outer wall 72 of the base 70.
The user interface circuit 262 is connected to the drive circuit 94. The drive circuit 94 includes a microprocessor and a driver for starting the electric motor 92. An electrical cord (not shown) for supplying power to the humidifier 10 passes through an opening formed in the base 70. The cord is connected to the plug. The drive circuit 94 includes a power supply connected to the cord. The user interface may also contain one or more LEDs that provide warning visual signals about the status of the humidifier 10. For example, the first LED 268 may light up if the water tank 120 becomes empty, and the drive circuit 94 receives a signal from the level sensor 206 .
There is also a humidity sensor 270 for detecting the relative humidity of the outdoor air and transmitting a signal with information about the measured relative humidity to the drive circuit 94. In this example, the humidity sensor 270 can be located directly behind the air inlet 74 and detect the relative humidity of the air flow drawn into the humidifier 10. The user interface may include a second LED 272, which is turned on by the drive circuit 94, when the output from the sensor 270 humidity certificates by the fact that the relative humidity H D of the air flow supplied to the humidifying apparatus 10 approaches or exceeds the required level of relative humidity H S, user defined.
To start using the humidifying device 10, the user presses the first button on the remote control, after which the remote control 260 generates a signal containing data indicative of pressing the specified first button. This signal is received by the receiver 264 of the user interface circuit 262. The user interface circuit 262 transmits button press information to the drive circuit 94, after which the drive circuit 94 turns on a UV lamp 160 for irradiating water located in the outlet chamber 144 of the water tank 140. In this example, the drive circuit 94 simultaneously drives an electric motor 92 that rotates the impeller 90. The rotation of the impeller 90 draws air into the housing 12 through the air inlet 74. The air flow passes through the casing 104 of the impeller and the guide vanes 100. In the stream after the guide vanes 100, part of the air discharged by the guide vanes 100 enters the duct 110 through the inlet port 112, while the rest of the air discharged by the guide vanes 100 is supplied through the first air passage 76 to the first air inlet 28 for the nozzle air 14. Thus, it can be considered that the impeller 90 and the electric motor 92 create the first air flow, which is supplied to the nozzle 14 through the first air passage 76 and which The fifth enters the nozzle 14 through the first air inlet 28.
The first air stream enters the first inner passage 46 at its lower end. The first air stream is divided into two air jets, which follow in opposite directions along the channel 20 of the nozzle 14. As the air jets pass through the first internal passage 46, air enters the mouth 48 of the nozzle 14. The flow rate of the air flow entering the mouth 48, preferably, it is substantially uniform along the length of the channel 20 of the nozzle 14. The mouth 48 directs the air flow towards the first air outlet 30 for the nozzle 14 through which it is discharged from the humidifier 10.
The air flow discharged from the first air outlet 30 leads to the creation of a secondary air stream due to the entrainment of outside air, in particular from the area around the first air outlet 30 and to the rear of the nozzle 14. A portion of such secondary air flow passes through the channel 20 of the nozzle 14, while the rest of the secondary air stream is entrained inside the air stream ejected from the first air outlet in front of the nozzle 14.
As noted above, when the impeller 90 rotates, air enters the second air passage 78 through the inlet port 112, forming a second air stream. The second air stream passes through the duct 110 and the inlet duct 210 of the water tank 210 and is discharged through the outlet port 214 above the water located in the outlet section of the outlet chamber 144. After the drive circuit 94 causes the converter 156 to vibrate to spray the water located in the outlet sections of the outlet chamber 144 of the water tank 140, suspended water droplets are formed above the water inside the outlet chamber 144 of the water tank 140. Converter 156 may be driven in response to user input received from the remote control 260 and / or after a fixed period of time after turning on the motor 92, which creates an air stream passing through the humidifier 10.
As aerosol spraying of the water in the water tank 140 takes place, the water tank 140 is continuously replenished with water from the water tank 120 through the inlet chamber 142, so that the water level inside the water tank 140 remains substantially constant, then as the water level inside the water tank 120 gradually decreases. As water enters the exhaust chamber 144 from the inlet chamber 142, it is guided by the deflector 200, passing along the upper portion of the tube 178 so that it is irradiated with ultraviolet rays coming out of the upper portion of the tube 178 before it passes through the opening 204 and is in the exhaust section of the exhaust chamber 144. Then, this water is irradiated with ultraviolet rays coming from the lower portion of the tube 178, before its aerosol spraying by the transducer 156.
Due to the rotation of the impeller 90, the weighed water droplets are entrained in the second air stream discharged from the exhaust port 214 of the intake duct 212. The moistened second air flow rises through the exhaust duct 218 to the second air inlet 58 of the nozzle 14 and enters the second inner passage 68 inside front section 18 of the nozzle 14.
At the base of the second inner passage 68, the second air stream is divided into two air jets that extend in opposite directions around the channel 20 of the nozzle 14. As the air jets pass through the second inner passage 68, each of the air jets is discharged through the second air outlet 60 . The ejected second air stream is fed away from the humidifying device 10 inside the air stream created by ejecting the first air stream from the nozzle 14, thereby allowing, after a short time, to feel a blow of moist air at a distance of several meters from the humidifying device 10.
The moist air stream is ejected from the nozzle 14 until the relative humidity H D of the air stream entering the humidifier 10, measured by the humidity sensor 270, reaches a level that at 20 ° C will be 1% higher than the relative humidity H S , set by the user using the third button on the remote control 260. After that, the discharge of the humidified air stream from the nozzle 14 can be stopped by the drive circuit 94, preferably by changing the vibration mode of the transducer 156. For example, the vibration frequency of the transducer 156 can be reduced to a frequency
below which aerosol spraying of the water present does not occur. Alternatively, the vibration amplitude of the transducer 156 can be reduced. Optionally, the motor 92 can also be stopped so that the air exhaust from the nozzle 14 is completely stopped. However, if the humidity sensor 270 is in close proximity to the electric motor 92, it is preferable that the electric motor 92 is continuously operated to prevent unwanted moisture fluctuations in the local environment of the humidity sensor 270.
As a result of the cessation of the discharge of the moist air stream from the humidifier 10, the relative humidity H D detected by the humidity sensor 270 starts to drop. As soon as the relative humidity in the environment near the humidity sensor 270 drops to a level that at 20 ° C will be 1% below the relative humidity level H S specified by the user, the drive circuit 94 will restart the vibration of the transducer 156 in the aerosol spray mode. If the motor 92 stopped, then the drive circuit 94 will simultaneously turn on the motor 92 again. As before, the humid air flow from the nozzle 14 will be released until the level of relative humidity H D detected by the humidity sensor 270 becomes at 20 ° C is 1% higher than the relative humidity level H S set by the user.
A similar sequence of turning on the converter 156 (and optionally the electric motor 92) to maintain the level of detected humidity approximately equal to the level set by the user continues until the first button is pressed again, or until a signal is received from the level sensor 206, indicating that the water level inside the tank 140 for water fell below the minimum level. After pressing the first button or after receiving a similar signal from the level sensor 206, the drive circuit 94 will turn off the electric motor 92, the converter 156 and the UV lamp 160 to turn off the humidifier 10. The drive circuit 94 also turns off these components of the humidifier 10 when receiving a signal from the sensor 208 an approach informing that the water tank 120 has been removed from the base 70.
