Description

Technical Field

[0001] This utility model relates to the field of home appliances, and in particular to a water tank for a dehumidifier and a dehumidifier. Background Technology

[0002] Air humidity has a significant impact on the comfort of the living environment. In southern regions and some coastal cities, residents often need specialized dehumidifiers to regulate indoor air humidity. Compared to air conditioners with built-in dehumidification functions, household dehumidifiers have significant advantages in dehumidification efficiency, energy consumption, and noise. They can also control humidity more precisely and have less impact on ambient temperature. Therefore, families with dehumidification needs usually purchase dedicated household dehumidifiers.

[0003] Household dehumidifiers are generally equipped with a removable water tank to hold the condensate produced. The heat exchanger and drip tray of the dehumidifier are usually located above the water tank, and the condensate flows downwards and falls into the water tank. However, in order to facilitate the removal of the water tank, the drain outlet of the drip tray needs to be higher than the water tank. This causes dripping noise when the condensate falls into the water tank, which increases noise pollution for users. Utility Model Content

[0016] Optionally, the upper part of the main board surface is spaced apart from the water-blocking plate.

[0017] The baffle also includes a water-blocking section, which bends and extends from the upper end of the main board surface toward the baffle plate.

[0018] Optionally, each water guide bar extends upwards above the water-blocking section.

[0019] Optionally, the second lateral end of the water-guiding base plate is spaced vertically from the surface of the cover to form a water-guiding hole.

[0025] The drip tray is located below the heat exchanger assembly and has a drip groove formed on its surface for collecting condensate from the heat exchanger assembly.

[0026] The water tank is detachably installed below the water receiving tray; the water tank can be any of the above-mentioned types.

[0027] Furthermore, a drain outlet is formed on the bottom surface of the water receiving tank to drain the condensate in the water receiving tank into the water receiving tank.

[0028] This utility model's water tank includes a tank body and a tank lid. The tank body defines an upward-opening water storage space.

[0046] Figure 1 This is a schematic diagram of a dehumidifier 10 according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic exploded view of the dehumidifier 10 shown.

[0047] refer to Figure 1 and Figure 2 As shown, this embodiment provides a dehumidifier 10, which generally includes a housing 20, a heat exchanger assembly 30, a compressor 60, a water tank 50, and a drip tray 41. The housing 20 has an air inlet and an air outlet on its surface, and defines a dehumidification space connecting the air inlet and outlet internally. The heat exchanger assembly 30 is disposed within the dehumidification space, so that air enters the housing 20 from the air inlet, passes through the heat exchanger assembly 30, and is blown out from the air outlet. The drip tray 41 is located below the heat exchanger assembly 30 and has a drip groove 41A formed on its surface for collecting condensate from the heat exchanger assembly 30. A water tank receiving cavity is also defined within the housing 20, located at the lower front side of the dehumidification space, and the water tank 50 is detachably disposed within the water tank receiving cavity.

[0048] The heat exchanger assembly 30 includes an evaporator and a condenser, and is typically arranged in multiple layers, with each of the evaporator and condenser having at least one layer. The evaporator is located on the side closer to the air inlet, while the condenser is located on the side relatively farther from the air inlet, so that air enters the casing 20 from the air inlet, flows through the evaporator and condenser successively, and is then blown out from the air outlet.

[0049] When the heat exchanger assembly 30 is operating, because the surface temperature of the evaporator is lower than the dew point temperature of the air, water vapor in the air condenses on the evaporator surface and flows into the water tank 50, thereby reducing the air humidity. The air flowing through the evaporator experiences a decrease in both humidity and temperature. This air then passes through the condenser, is heated, and is discharged from the casing 20 through the outlet. Therefore, the outlet air temperature and inlet air temperature of the dehumidifier 10 are similar, and it does not significantly affect the ambient air temperature while dehumidifying.

[0050] In this embodiment, the heat exchanger assembly 30 is located in the upper part of the dehumidification space, while the water tank 50 is located in the lower part of the dehumidification space. The water receiving tray 41 separates the heat exchanger assembly 30 and the water tank 50 vertically, so that the condensate formed on the surface of the evaporator flows downward to the water receiving tray 41 under its own gravity and eventually flows into the water tank 50.

[0051] Figure 3 yes Figure 1 A schematic diagram of the support frame 40 of the dehumidifier 10 shown.

[0052] The drip tray 41, located below the heat exchanger assembly 30, not only forms a drip trough 41A to collect condensate from the heat exchanger assembly 30, but also supports and secures the heat exchanger assembly 30. To better secure the drip tray 41 within the housing 20, this embodiment integrates the drip tray 41 with the partition plate 42, forming a support frame 40. The support frame 40 includes the drip tray 41 and the partition plate 42, which extends downwards from the rear of the drip tray 41 to divide the lower part of the dehumidification space.

[0053] refer to Figure 2 and Figure 3 As shown, in this embodiment, the partition plate 42 extends downward from the rear side of the water tray 41 to connect with the bottom plate 24 of the housing 20, thereby being detachably fixed to the bottom plate 24 of the housing 20 and reliably supporting the rear part of the water tray 41. The partition plate 42 divides the lower part of the dehumidification space into front and rear sections, wherein the front side of the dehumidification space below the water tray 41 serves as a water tank receiving cavity for accommodating the water tank 50, while the rear side of the dehumidification space is typically used for housing the compressor 60. (See reference...) Figure 3 As shown, in some alternative embodiments, the transverse middle portion of the partition plate 42 may be bent forward to avoid the compressor 60.

[0054] In some alternative embodiments, the lower part of the front surface of the housing 20 has an opening, and the water tank 50 is detachably disposed within the water tank receiving cavity. The water tank 50 of this embodiment may be designed with a drawer-type structure including a handle and a slide rail, so that the water tank 50 can be pulled out from the opening of the housing 20 and disposed within the water tank receiving cavity.

[0055] refer to Figure 2 and Figure 3 As shown, in some alternative embodiments, the support frame 40 may further include two support plates 43. The two support plates 43 extend downward from one lateral side of the water receiving tray 41, respectively.

[0056] In other words, the support frame 40 in this embodiment consists of a water receiving tray 41, a partition plate 42 extending downward from the rear side of the water receiving tray 41, and two support plates 43 extending downward from one lateral side of the water receiving tray 41. The two lateral ends of the partition plate 42 are respectively connected to the two support plates 43, and are integrally formed with the water receiving tray 41 to constitute the support frame 40 of the dehumidifier 10. The support frame 40 in this embodiment, together with the bottom plate 24 of the casing 20, defines a water tank receiving cavity with an opening facing forward.

[0057] The lower ends of the partition plate 42 and the two support plates 43 of the support frame 40 are detachably fixed to the base plate 24 of the housing 20. The lower ends of the partition plate 42 and the two support plates 43 can form a claw-like fixing structure and engage with the base plate 24 of the housing 20. The lower ends of the partition plate 42 and the two support plates 43 can also be fastened to the base plate 24 of the housing 20 with screws or other means. The support plates 43 and the partition plates 42 respectively support the lateral sides and rear of the water receiving tray 41, further improving the fixing effect of the water receiving tray 41 within the housing 20.

[0058] Figure 4 yes Figure 1 A partial cross-sectional schematic diagram of the dehumidifier 10 is shown.

[0059] refer to Figure 3 and Figure 4 As shown, in some optional embodiments, the bottom surface of the water receiving tank 41A has a plurality of upwardly protruding ribs 411 to support the heat exchanger assembly 30 and to space the heat exchanger assembly 30 from the bottom surface of the water receiving tank 41A.

[0060] In this embodiment, the location and extension direction of the ribs 411 generally correspond to the shape of the heat exchanger assembly 30, so that the bottom surface of the heat exchanger assembly 30 is subjected to relatively uniform force, reducing the deformation of the heat exchanger assembly 30 under pressure. By supporting the heat exchanger assembly 30 and spacing it from the bottom surface of the water receiving tank 41A, it is possible to prevent the condensate dripping from the heat exchanger assembly 30 from continuing to contact the heat exchanger assembly 30, allowing the water in the water receiving tank 41A to drain more smoothly.

[0061] refer to Figure 4 As shown, in some optional embodiments, a drain outlet 41C is formed on the bottom surface of the water receiving tank 41A to drain the condensate in the water receiving tank 41A to the water tank 50.

[0062] The number of drain outlets 41C can be one or more. When there are multiple drain outlets 41C, they can be concentrated in one location within the water receiving tank 41A or distributed in multiple locations within the water receiving tank 41A. In some optional embodiments, the sidewall of the drain outlet 41C can protrude upwards and be higher than the bottom surface of the water receiving tank 41A. At the same time, a notch can be formed on the sidewall of the drain outlet 41C to guide condensate water to concentrate at the notch and drain into the drain outlet 41C, making the flow direction of condensate water from the water receiving pan 41 to the water tank 50 more controllable.

[0063] To increase the air inlet area of ​​the dehumidifier 10 and improve its dehumidification efficiency, refer to Figure 1 and Figure 2 As shown, in some optional embodiments, the housing 20 includes a top wall 21 with an air outlet, a plurality of first side walls 22 with air inlets, a second side wall 23 without air inlets, and a bottom plate 24; wherein the second side wall 23 is located on the rear side of the housing 20. Figure 1 and Figure 2 In the illustrated embodiment, the housing 20 is designed as a cuboid and has three first sidewalls 22 and one second sidewall 23. The second sidewall 23, which does not have an air inlet, can typically serve as the rear sidewall of the dehumidifier 10 so that the dehumidifier 10 can be placed against a wall. The other sidewalls of the housing 20 serve as the first sidewalls 22, and all have air inlets on their surfaces to increase the air intake of the dehumidifier 10 and improve dehumidification efficiency.

[0064] The design of the air outlet on the top wall 21 reduces interference between the air intake and exhaust of the dehumidifier 10, thereby improving the overall airflow efficiency of the environment. In some other embodiments, the casing 20 may also be designed as a triangular prism, hexagonal prism, or other shapes, and has a varying number of first sidewalls 22 and a second sidewall 23, which is not limited here.

[0065] Corresponding to the plurality of first sidewalls 22 with air inlets, the heat exchanger assembly 30 of this embodiment is bent along the inner side of the plurality of first sidewalls 22, and the side surface of the heat exchanger assembly 30 is close to the air inlets on the plurality of first sidewalls 22.

[0066] refer to Figure 2 As shown, since the casing 20 in this embodiment is rectangular, the heat exchanger assembly 30 is U-shaped. This allows the side surface of the heat exchanger assembly 30 to be as close as possible to the air inlets on the multiple first sidewalls 22, thereby increasing the facing area between the air inlets and the heat exchanger assembly 30 and ensuring that the air entering the casing 20 makes more thorough contact with the heat exchanger assembly 30. The side surface of the heat exchanger assembly 30 is close to the air inlets on the multiple first sidewalls 22, and its two ends are close to the second sidewall 23, so that after air enters the casing 20 from the air inlets, it passes through the heat exchanger assembly 30 and is blown out from the air outlet.

[0067] It is understandable that when the casing 20 is different Figure 2 Other shapes in the embodiments, or the extending direction of the first sidewall 22 of the housing 20, may differ. Figure 2 In the embodiment, the bending shape of the heat exchanger assembly 30 may also be different. Figure 2 Example.

[0068] refer to Figure 2 As shown, in some optional embodiments, the top wall 21 and the plurality of first side walls 22 are integrally formed, and the second side wall 23 and the bottom plate 24 are respectively detachably disposed relative to the top wall 21 and the plurality of first side walls 22.

[0069] The dehumidification space is the entire internal space defined by the top wall 21, first side wall 22, second side wall 23, and bottom plate 24 of the casing 20. Other components, including the heat exchanger assembly 30, compressor 60, and support frame 40, are all housed within the dehumidification space. In this embodiment, the top wall 21 and multiple first side walls 22 are designed as a single integral part, and the second side wall 23 and bottom plate 24 are designed to be detachable from the top wall 21 and multiple first side walls 22, respectively. This allows the second side wall 23 to be detached independently from other parts of the casing 20, and the top wall 21 and first side walls 22 can be disassembled upwards as a whole, thereby exposing other components housed within the dehumidification space and reducing the assembly and maintenance difficulty of the dehumidifier 10.

[0070] Furthermore, in some alternative embodiments, the shape of the water receiving tank 41A corresponds to that of the heat exchanger assembly 30. A vent 41B is also formed in the center of the water receiving pan 41; the water receiving pan 41 protrudes upward at the edge of the vent 41B to separate the water receiving tank 41A and the vent 41B.

[0071] In some alternative embodiments, the water receiving tray 41 may form a mesh grille at the vent 41B, such as Figure 3 As shown.

[0072] The dehumidifier 10 discharges condensate from the drain outlet 41C of the water tray 41 into the water tank 50, and there is a significant height difference between the drain outlet 41C and the bottom surface of the water tank 50. To avoid the condensate falling directly into the water tank 50 and causing dripping noise, this invention also improves the structure of the water tank 50.

[0073] Figure 5 yes Figure 1 A schematic diagram of the water tank 50 of the dehumidifier 10 shown; Figure 6 yes Figure 5 A partially enlarged schematic diagram of part A of the water tank 50 shown; Figure 7 yes Figure 5 A partially enlarged schematic diagram of part B of the water tank 50 shown.

[0074] In some alternative embodiments, the water tank 50 includes a tank body 52 and a tank cover 51. The tank body 52 defines an upward-opening water storage space. The tank cover 51 is disposed on the upper part of the tank body 52 for closing the opening of the tank body 52. ​​The tank cover 51 includes a cover body 511 and a water guide groove 512 located directly below the drain outlet 41C and recessed downward relative to the cover body 511; a water guide hole 512A communicating with the water storage space is formed on one side of the water guide groove 512.

[0075] refer to Figure 5 As shown, the cover 51 of the box cover 51 is roughly flat, and the water guide groove 512 is recessed downward relative to the cover 511, with a water guide hole 512A formed on one side. This allows the condensate draining downward from the drain outlet 41C of the water tray 41 to first fall into the water guide groove 512 on the box cover 51, and the falling speed of the water is reduced. Due to the buffering effect of the box cover 51, the flow rate of the condensate as it continues to drain into the box body 52 through the water guide hole 512A on the water guide groove 512 is slowed down, thus reducing the dripping noise.

[0076] refer to Figure 4 and Figure 7 As shown, in order to more effectively eliminate dripping noise, in some optional embodiments, a guide plate 521 extending downward from the water guide hole 512A is provided inside the housing 52 so that the water flowing through the water guide hole 512A flows downward along the guide plate 521.

[0077] In this embodiment, the water tank 50 is equipped with an inclined guide plate 521, which allows condensate to flow along the guide plate 521 instead of dripping directly into the water tank 50, effectively reducing or even eliminating the dripping noise of the water tank 50.

[0078] In some alternative embodiments, the water channel 512 has a water-guiding base plate 5121 that extends downwardly from a first transverse end to a second transverse end. The flow guide plate 521 extends downwardly from the second transverse end to the first transverse end.

[0079] The lateral direction described in this embodiment is consistent with the lateral direction of the dehumidifier 10 and the water tank 50, and is distinct from the front-to-back direction of the dehumidifier 10. (Reference) Figure 4 As shown, the first horizontal end of the water guide channel 512 is located on the left side of the diagram, while the second horizontal end is located on the right side. It can be understood that the first horizontal end and the second horizontal end are only relative orientation concepts and do not represent fixed left or right ends. That is to say, in some optional embodiments, the first horizontal end of the water guide channel 512 can also be located on the right side.

[0080] In this embodiment, the water guide channel 512 has a water guide base plate 5121 that extends downwardly from a first transverse end to a second transverse end, while a guide plate 521 with the opposite inclination direction is provided inside the housing 52. A water guide hole 512A is formed at the second transverse end of the water guide base plate 5121. After passing through the water guide hole 512A, condensed water flows to the surface of the guide plate 521 near the first transverse end of the water guide channel 512 and continues to flow downward along the surface.

[0081] refer to Figure 4 and Figure 6 As shown, in some alternative embodiments, the second lateral end of the water-guiding base plate 5121 is vertically spaced from the surface of the cover 511 to form a water-guiding hole 512A.

[0082] In this embodiment, the water guide hole 512A is not formed on the surface of the water guide base plate 5121. Instead, the water guide hole 512A is formed by the height difference between the end of the water guide base plate 5121 and the surface of the cover 511 caused by its downward inclined extension. This allows the condensate in the water guide groove 512 to flow along the water guide base plate 5121 and exit from the water guide hole 512A in the same direction as the extension direction of the water guide base plate 5121, i.e., it is tilted downward and discharged into the guide plate 521 instead of being discharged vertically downward. Therefore, the water guide base plate 5121 and the guide plate 521 work together to effectively reduce the flow rate of the condensate.

[0083] In some alternative embodiments, the deflector 521 includes a main body surface 5211 extending downward at an angle, and a plurality of water-guiding ribs 5212 protruding from the surface of the main body surface 5211 and spaced apart; a water-guiding gap extending longitudinally is defined between two adjacent water-guiding ribs 5212.

[0084] refer to Figure 4 and Figure 7 As shown, in this embodiment, the guide plate 521, in addition to the flat main plate surface 5211, also has multiple water-guiding ribs 5212 that protrude from the surface of the main plate surface 5211 and are spaced apart. A longitudinally extending water-guiding gap is defined between every two adjacent water-guiding ribs 5212. Condensate draining from the water-guiding hole 512A into the guide plate 521 flows downwards along the water-guiding gap between adjacent water-guiding ribs 5212. The water-guiding ribs 5212 can divert condensate while increasing the surface tension of the water flow, thereby reducing the flow rate of the condensate and essentially eliminating dripping noise.

[0085] In some alternative embodiments, a baffle plate 522 is provided inside the water tank 50. The upper end of the baffle plate 522 is higher than the second end of the water guide plate 5121, and the water guide hole 512A is directly opposite the baffle plate 522. The upper end of the guide plate 521 is connected to the baffle plate 522 and is lower than the water guide hole 512A, so that the water flowing through the water guide hole 512A flows to the surface of the baffle plate 522 and then flows downward along the guide plate 521.

[0086] In this embodiment, at least a portion of the baffle plate 522 corresponding to the guide plate 521 extends in the front-to-back direction within the housing 52. The upper end of the baffle plate 522 is higher than the second end of the guide plate 5121, and the guide hole 512A is directly opposite the baffle plate 522. After the condensate passes through the guide hole 512A, it can flow directly to the surface of the baffle plate 522 and further flow downward along the surface of the baffle plate 522 to the guide plate 521. Therefore, the condensate is less likely to splash.

[0087] In some alternative embodiments, the baffle plate 522 can be integrally formed with the tank body 52 and can extend in the front-rear direction to connect with the front or rear wall of the tank body 52, laterally dividing the water storage space into multiple smaller areas that are only partially connected. Due to the obstruction of the baffle plate 522, the oscillation amplitude of the condensate contained in the water tank 50 is smaller during handling and movement. Even if the water tank 50 contains a large amount of condensate, its overall center of gravity will not frequently shift excessively when the user handles it, causing the water tank 50 to shake. This makes handling easier for the user and reduces the likelihood of water spillage.

[0088] It should be noted that in this embodiment, the number of water baffles 522 and guide plates 521 installed in the box 52, as well as the number of water guide grooves 512 installed on the box cover, are not limited to one, that is, there can be one or more.

[0089] refer to Figure 4 and Figure 7 As shown, in some alternative embodiments, the upper end of the main board surface 5211 is spaced apart from the water baffle 522. The guide plate 521 also includes a water-blocking section that bends and extends from the upper end of the main board surface 5211 toward the water baffle 522.

[0090] Because the water storage space inside the housing 52 has a certain depth, the inclination angle of the main surface 5211 of the guide plate 521 relative to the vertical direction is relatively small. In this embodiment, a water-blocking section 5213 extending towards the water baffle 522 is further formed at the upper end of the main surface 5211, increasing the inclination angle of the guide plate 521 and the water baffle 522 relative to the vertical direction. This causes the condensate to flow downward along the surface of the water baffle 522 to the upper end of the guide plate 521, where it is affected by the water-blocking section 5213 and slowed down, thereby further reducing the flow velocity of the condensate on the guide plate 521.

[0091] In some alternative embodiments, each water-guiding rib 5212 extends upward above the water-blocking section 5213. That is, before the condensate flows downward along the surface of the baffle plate 522 and contacts the water-blocking section 5213, it will first come into contact with the water-guiding rib 5212 and be diverted. Under the influence of the water-guiding rib 5212, the condensate is subjected to stronger surface tension and is less likely to splash when it contacts the water-blocking section 5213.

[0092] In some alternative embodiments, the water guide channel 512 further has water guide side plates 5122 located on both sides of the water guide base plate 5121 in the front-back direction. The water guide side plates 5122 are used to guide and restrict the flow direction of condensate in the water guide channel 512 and prevent condensate from being discharged into the water storage space from a position other than the water guide hole 512A.

[0093] In some alternative embodiments, the lid also includes a flange 513 disposed around the periphery of the lid body 511 and above the surface of the lid body 511. The flange 513 is higher than the height of the lid body 511, thus preventing condensate overflowing from the water channel 512 from flowing further outward.

[0094] In some alternative embodiments, at least a portion of the flange 513 may be formed with a downward-facing fixing groove, the shape of which corresponds to the shape of the side wall of the housing 52, so that the side wall of the housing 52 can extend into the fixing groove to secure the lid.

[0095] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
