Description

Technical Field

[0001] This application relates to the field of dehumidifier technology, and in particular to a dehumidifier water tank and a dehumidifier. Background Technology

[0002] Dehumidifiers are common household appliances used to regulate ambient humidity. They typically consist of a main unit and a retractable water tank housed within the main unit's cavity, used to collect condensation from the air. To ensure the water tank remains stable after being installed in the cavity and to prevent accidental slippage or shaking, a positioning and locking mechanism is usually installed between the water tank and the cavity.

[0003] Currently, a common locking method involves installing elastic latches on the inner walls of the left and right sides of the receiving cavity, and providing protrusions on the corresponding side walls of the water tank to engage with the latches. When the water tank is pushed into the receiving cavity, the protrusions on the side walls of the water tank will pass over and engage with the elastic latches, thereby locking the water tank. However, the above-mentioned prior art has at least the following drawbacks: First, since the latches are usually located in the lower middle or lower side of the receiving cavity, users must bend over or even squat down to align the tank and pull it out forcefully when removing it. For larger tanks, multiple latches are often required to ensure the reliability of the fixation, which means that users need to apply more force to release the tank, making the operation laborious and unsightly.

[0004] Secondly, once the water tank is removed, the clip structure on the inner wall of the receiving cavity is completely exposed. This exposed mechanical structure contradicts the dehumidifier's minimalist, home-friendly design philosophy, detracts from the product's overall aesthetics, and provides users with a poor visual experience.

[0005] Furthermore, traditional water tanks often employ complex mold structures to achieve intricate features like handles, requiring core pulling and parting in multiple directions. This inevitably creates noticeable mold joint lines on the tank's surface, particularly near the handles. These joint lines not only affect the appearance but also diminish the product's overall quality and perceived value. Summary of the Invention

[0006] The purpose of this application is to provide a dehumidifier water tank and a dehumidifier with a snap-fit ​​structure that can be hidden.

[0007] To achieve the above objectives, in a first aspect, embodiments of this application provide a dehumidifier water tank, which is removably disposed within the receiving cavity of a dehumidifier, the water tank comprising: A box body and a cover, wherein the cover is located at the top opening of the box body; A handle, which is pivotally connected to the top of the box, forms a lifting gap between the handle and the top surface of the box, suitable for a hand to reach in; A spring-loaded buckle structure is provided between the handle and the top wall of the receiving cavity, or between the cover and the top wall of the receiving cavity. The spring-loaded buckle structure has a locked state and an unlocked state. When the water tank is pushed into the receiving cavity, the spring-loaded buckle structure is in the locked state, and the water tank is relatively fixed in the receiving cavity by the spring-loaded buckle structure. When the handle is pulled upward, it rotates around its pivot point, and the snap-lock structure is in the unlocked state, so that the water tank can be pulled out from the receiving cavity.

[0012] Preferably, the top surface of the second protrusion includes a first surface, a second surface, and a third surface connected in sequence, the third surface being close to the front side of the housing, and the angle of inclination of the third surface relative to the horizontal plane being greater than the angle of inclination of the first surface relative to the horizontal plane; wherein, the second surface is parallel to the horizontal plane.

[0013] Preferably, the cover includes a fixed cover and a flip cover, the flip cover being rotatably connected to the fixed cover; the flip cover can rotate between a first position and a second position, the flip cover forming a drain outlet when it is in the second position, and the drain outlet closing when it is in the first position, wherein, when the water tank is tilted forward, the flip cover can rotate from the first position to the second position under its own weight and the impact of the water flow.

[0014] Preferably, the top surface of the raised portion is recessed with a water receiving groove, which is used to receive condensate flowing out of the dehumidifier's water receiving tray. The side wall of the front side of the water receiving groove is provided with a drain interface, and the raised portion is provided with a first insertion hole corresponding to the position of the drain interface. The drain interface is used to connect to an external drain pipe, or to drain the water in the water receiving groove into the water tank when not connected to an external drain pipe.

[0015] Secondly, embodiments of this application provide a dehumidifier, including a body and a dehumidifier water tank as described in any embodiment of the first aspect, wherein a receiving cavity is provided on one side of the body, and the dehumidifier water tank is removably disposed in the receiving cavity.

[0016] Preferably, the top wall of the receiving cavity has a through hole, and an elastic support arm with one end connected to the wall of the through hole is provided in the through hole, and the other end of the elastic support arm protrudes downward to form an elastic latching protrusion that engages with the snap fastener structure; or, the top wall of the receiving cavity integrally protrudes downward to form a first protrusion that engages with the snap fastener structure.

[0017] The dehumidifier water tank and dehumidifier designed in this application integrate unlocking and pulling actions by setting a spring-loaded buckle structure between the handle or cover and the top wall of the receiving cavity. Users can unlock and pull out the water tank by pulling the handle upwards while standing, eliminating the need to bend over and saving effort. After the water tank is removed, the buckle is hidden at the top, improving the product's aesthetics. In addition, the gravity-flipping cover enables hands-free water emptying, and the integrated soft rubber stopper and water pump interface solution take into account both the convenience of multi-mode drainage and a clean appearance.

Detailed Implementation

[0042] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0043] like Figure 1 , Figure 8 , Figure 9As shown, this application embodiment provides a dehumidifier water tank 100 and a dehumidifier 200 including the water tank 100. The water tank 100 and dehumidifier 200 disclosed in this application integrate the unlocking and pulling actions by setting a spring-loaded structure between the handle 20 and the top wall of the receiving cavity 201, or between the cover and the top wall of the receiving cavity 201. The user does not need to bend over; they can unlock the spring-loaded structure by pulling the handle 20 upwards while standing, thus effortlessly releasing the water tank 100 and pulling it out smoothly, effectively improving the convenience and comfort of operation. At the same time, after the water tank 100 is removed, the latching part of the spring-loaded structure located on the top wall of the receiving cavity is hidden because it is located at the top, avoiding structural exposure and improving the overall aesthetics of the product.

[0044] Specifically, such as Figure 1 , Figure 8 , Figure 9 As shown, the dehumidifier 200 provided in this embodiment includes a body 204 and a dehumidifier water tank 100. A receiving cavity 201 is provided on one side of the body 204, and the dehumidifier water tank 100 is removably disposed in the receiving cavity 201. In use, after the dehumidifier water tank 100 is pushed into the receiving cavity 201, the spring-loaded structure is locked, thereby relatively and fixedly locking the water tank 100 in the receiving cavity 201 of the body 204. When it is necessary to remove the water tank 100, the user's fingers can be easily inserted into the lifting gap 30 formed between the handle 20 and the top surface of the body 10, and the handle 20 is pulled upward. The handle 20 rotates around its pivot point, so that the spring-loaded structure is unlocked, thereby easily unlocking and pulling out the water tank 100.

[0045] Next, the specific structural features of the dehumidifier water tank 100 in the embodiments of this application will be described in detail with reference to the accompanying drawings.

[0046] like Figures 8 to 10 As shown in the embodiment of this application, the dehumidifier water tank 100 mainly includes a housing 10, a cover 13 located at the top opening of the housing 10, and a handle 20. The housing 10 is used to contain the collected condensate. The handle 20 is pivotally connected to the top of the housing 10, specifically mounted on the cover 13 via a pivot shaft, forming a pull gap 30 between the handle 20 and the top surface of the housing 10, providing convenient operating space for the user's fingers.

[0047] In one embodiment, the spring-loaded structure is disposed between the cover 13 and the top wall of the receiving cavity 201. Specifically, as... Figure 18 , Figure 23As shown, the snap-fit ​​structure includes a groove 71 on the top of the cover 13, a movable block 72 partially disposed within the groove 71 and movable in a vertical direction, and an elastic element 73 (e.g., a coil spring or sheet spring) disposed within the groove 71 and abutting against the lower part of the movable block 72. Correspondingly, a first protrusion 80 is provided on the top wall of the receiving cavity 201. The elastic element 73 provides an upward elastic force in its natural state, causing the movable block 72 to extend out of the groove 71.

[0048] Furthermore, to ensure the stability and safety of the lifting and lowering of the movable block 72, two grooves 71 are provided at intervals on the top of the cover 13. Correspondingly, two sets of movable blocks 72 and elastic elements 73 are also provided to provide a more balanced fastening force. Guide slopes 74 are provided on the front and rear sides of the top of the movable block 72, and slopes are provided on the front and rear sides of the first protrusion 80, thus forming a guide surface. The connection between the slopes on the front and rear sides is smoothly transitioned, and the first protrusion 80 has an overall V-shaped profile.

[0049] A through hole is formed in the side wall of the groove 71, and an anti-detachment hook 721 extends into the through hole. The upper side wall of the through hole forms an anti-detachment step 711, and an anti-detachment hook 721 is correspondingly provided on the outer side wall of the movable block 72. Under the upward elastic force of the elastic member 73, the anti-detachment hook 721 abuts against the anti-detachment step 711, thereby limiting the upward movement of the movable block 72 and preventing it from popping out of the groove 71.

[0050] Furthermore, the movable block 72 has a hollow structure with a guide rod 722 extending downwards from the center of its bottom end. A through hole is provided in the bottom wall of the groove 71, and the end of the guide rod 722 facing away from the movable block 72 passes through the bottom wall of the groove 71 (i.e., the through hole). An elastic element 73 (such as a coil spring) is sleeved on the outer periphery of the guide rod 722, with its two ends abutting against the bottom surface of the movable block 72 and the bottom wall of the groove 71, respectively. This guide rod 722 structure not only provides reliable positioning for the elastic element 73, preventing the spring from bending or jamming under force, but its portion extending through the bottom wall also provides good lifting and lowering guidance, ensuring smooth movement of the movable block 72.

[0051] When the water tank 100 is pushed into the receiving cavity 201, the movable block 72 is pressed by the guide surface of the first protrusion 80, overcoming the elastic force of the elastic element 73 and retracting downwards. After passing the locking position, it returns to its original position under the action of elastic force, thus elastically engaging with the first protrusion 80. At this time, the spring-loaded structure is in the locked state, and the water tank 100 is securely fixed in the receiving cavity 201. When the user pulls the handle 20 upwards through the lifting gap 30, the handle 20 rotates around its pivot point, causing the first protrusion 80 to press against the top of the movable block 72, forcing the movable block 72 to move downwards against the elastic force of the elastic element 73, thereby causing the movable block 72 to retract downwards and disengage from the first protrusion 80. At this time, the spring-loaded structure switches to the unlocked state, and the user can then easily pull the water tank 100 out of the receiving cavity 201.

[0052] In this embodiment, as Figure 23 As shown, the top wall of the receiving cavity 201 is integrally formed with a first protrusion 80 that engages with the spring-loaded structure. The first protrusion 80 is a hard snap protrusion, which is adapted to the spring-loaded structure on the cover 13, which itself has an elastic element 73 and a movable block 72 that provide retraction space, so as to provide a stable limiting effect in the locked state.

[0053] In another embodiment, such as Figure 3 , Figure 5 , Figure 10 As shown, the snap-lock structure is directly disposed between the handle 20 and the top wall of the receiving cavity 201. Specifically, a second protrusion 40 is integrally formed on the top surface of the handle 20, and correspondingly, a second snap 50 is disposed on the top wall of the receiving cavity 201 of the dehumidifier 200.

[0054] When the water tank 100 is pushed into the receiving cavity 201, the second protrusion 40 on the handle 20 is elastically engaged with the second buckle 50 to lock the water tank 100 and prevent it from shaking. When the user pulls the handle 20 upward through the lifting gap 30, the handle 20 rotates around its pivot point to drive the second protrusion 40 to squeeze and disengage from the second buckle 50 at a certain angle, thereby unlocking the water tank 100 so that it can be pulled out of the receiving cavity 201.

[0055] In this embodiment, as Figure 5 , Figure 9 As shown, a through hole 202 is provided at the front end of the top wall of the receiving cavity 201. A cantilevered elastic support arm is provided inside the through hole 202. One end of the elastic support arm is connected to the wall of the through hole 202, and the other end protrudes downward as a free end to form an elastic latch. The elastic support arm and the elastic latch together constitute the aforementioned second latch 50. Because the second latch 50 is elastic, it can elastically avoid and engage with the rigid second protrusion 40 provided on the top surface of the handle 20. When the water tank is pushed in, the second protrusion 40 pushes open the second latch 50, which serves as the elastic support arm, and after passing it, the elastic support arm springs back to lock.

[0056] In some embodiments, such as Figure 10 , Figure 11 , Figure 13As shown, the handle 20 includes a grip portion 21 for easy holding by the user and connecting portions 22 connected to both sides of the grip portion 21. A second protrusion 40 is provided on the top surface of the connecting portion 22. Specifically, the second protrusion 40 can be integrally formed and located approximately in the middle of the top surface of the connecting portion 22. In order to form a lifting gap 30 and provide a stable lever fulcrum, the connecting portion 22 has an arc-shaped longitudinal section, that is, the overall shape of the connecting portion 22 is an arc-shaped strip structure, and the connecting portion 22 is curved upward. In conjunction with this, the top of the cover 13 is provided with a raised portion 11 that extends upward above the upper surface of the cover 13. The two sides of the raised portion 11 are recessed downward to form bosses 112. The bosses 112 have inclined surfaces 1121 for abutting and supporting the connecting portion 22. The front side of the inclined surface 1121 is higher and the rear side is lower. When the handle 20 is in the lowered state, the arc-shaped lower surface of the connecting portion 22 abuts and is stably supported on the inclined surface 1121. This design not only ensures structural stability but also guarantees a constant lifting gap 30. In this embodiment, the handle 21 and the connecting part 22 are hollow structures with open bottom surfaces, which reduces weight and facilitates mold opening.

[0057] In some embodiments, to achieve smooth engagement and disengagement, such as Figure 3 , Figure 5 , Figure 6 As shown, the top surface of the second protrusion 40 includes a first surface 41, a second surface 42, and a third surface 43 connected in sequence. The first surface 41 serves as an inlet ramp, guiding the elastic locking protrusion when the water tank is pushed in. The second surface 42 is parallel to the horizontal plane; when engaged, the elastic locking protrusion abuts against it, forming a stable locking state. The third surface 43 is close to the front of the tank body 10, and its angle of inclination relative to the horizontal plane is greater than that of the first surface 41. It serves as an unlocking surface; when the handle 20 is pulled upwards, the third surface 43 forcefully squeezes the elastic locking protrusion at a larger angle, allowing it to disengage quickly and effortlessly.

[0058] In another embodiment, the longitudinal section of the second protrusion is V-shaped, and the corners of the first and third surfaces are set as smooth transitions.

[0059] In some embodiments, the cross-sectional shape of the movable block 72 is the same as the cross-sectional shape of the second protrusion 40. That is, the movable block 72 may also have a first surface, a second surface, and a third surface connected in sequence.

[0060] In some embodiments, such as Figure 12 , Figure 13As shown, the cover 13 includes a fixed cover 131 and a flip cover 132. The flip cover 132 is rotatably connected to the fixed cover 131, and the length of the rear side of the fixed cover 131 is equal to the length of the flip cover 132. The flip cover 132 can rotate between a first position and a second position. When the flip cover 132 is in the second position, it forms a drain outlet 133. When the flip cover 132 is in the first position, the drain outlet 133 is closed. When the water tank 100 tilts forward, the flip cover 132 can rotate from the first position to the second position under its own weight and the impact of the water flow, without requiring manual opening by the user, greatly facilitating one-handed operation. In this embodiment, the fixed cover 131 is detachably connected to the tank 10 or fixed to the tank 10 by ultrasonic welding.

[0061] Utilizing this structural design, in the normal horizontal placement state, the flip cover 132 remains in the closed first position, its surface being essentially flush with the fixed cover 131, completely covering the top opening of the housing 10, effectively preventing dust and other debris from falling in; Figure 12 As shown, when a user needs to empty the water inside the tank 10 and tilts it forward, the flip cover 132 automatically flips from the first position to the open second position under its own weight. This flipping action exposes the top area of ​​the tank 10 that was originally covered, thus forming a spacious drain outlet 133 at the front of the tank 10, allowing water to flow out smoothly. When the user returns the tank 10 to the horizontal position, the flip cover 132 also automatically returns to the closed first position under the action of gravity.

[0062] In order to achieve the rotatable connection between the flip cover 132 and the fixed cover 131, one of the fixed cover 131 and the flip cover 132 is provided with a rotating shaft, and the other is provided with a shaft hole or a retaining groove that rotatably engages with the rotating shaft.

[0063] In one specific embodiment, such as Figure 16 , Figure 17As shown, the fixed cover 131 is provided with a mounting portion 1311, and shafts 1312 extending from both ends of the mounting portion 1311 serve as pivots. To improve the stability of the structure, support ribs 1313 connected to the fixed cover 131 are provided at both ends of the shafts 1312. The flip cover 132 is provided with a pair of elastic arms 1321 that engage with the shafts 1312. A retaining groove 1322 with an opening is formed between the pair of elastic arms 1321 to accommodate the shafts 1312. In this way, the flip cover 132 is detachably rotatably connected by engaging the shafts 1312 into the retaining grooves 1322. In addition, to improve the durability of the elastic arms 1321 during repeated opening and closing, a reinforcing rib 1323 is integrally formed on the outer side of each elastic arm 1321 to effectively prevent the elastic arms 1321 from being damaged due to deformation under stress. The bottom of the retaining groove 1322 is also provided with an arc-shaped support rib 1327. When the shaft 1312 is pressed into the retaining groove 1322, the arc-shaped support rib 1327 at the bottom of the groove can stably support it and ensure smooth rotation.

[0064] In another specific embodiment, such as Figure 22 , Figure 23 As shown, the mounting portion 1311 of the fixed cover 131 has a shaft hole 1314, and correspondingly, the flip cover 132 has a rotating shaft 1328 protruding at the position corresponding to the shaft hole 1314. During assembly, the rotating shaft 1328 on the flip cover 132 is inserted into the shaft hole 1314 of the fixed cover 131 to achieve a rotatable connection between the two. This insertion structure can also ensure that the flip cover 132 can flip smoothly under its own weight and water flow impact, and the structure is simple and the connection is reliable.

[0065] In some embodiments, such as Figure 8 , Figure 10 , Figure 17 As shown, the top surface of the raised portion 11 is recessed with a water receiving trough 111 for collecting condensate. This water receiving trough 111 is used to collect condensate flowing from the water receiving tray 203 below the heat exchanger (not shown) of the dehumidifier 200 and to initially collect it. Specifically, as... Figure 4 , Figure 7 , Figure 9 , Figure 13 As shown, the bottom of the water receiving tray 203 of the dehumidifier 200 is provided with a drain outlet 2031 corresponding to the position of the water receiving trough 111. A drain interface 1111 is provided on the front side wall of the water receiving trough 111. A first insertion hole 113 is provided on the raised portion 11 corresponding to the position of the drain interface 1111, i.e., the opening of the first insertion hole 113 faces the user-facing side of the raised portion 11. The drain interface 1111 is used to connect to an external drain pipe, or to drain water from the water receiving trough 111 into the water tank 100 when no external drain pipe is connected. In this embodiment, the drain interface 1111 can be a quick-connect connector.

[0066] The cover 13 provided in this embodiment has two working modes: Water storage mode: Under normal use conditions without continuous drainage, such as... Figure 4 , Figure 17 As shown, without any additional operation by the user, the condensate dripping from the dehumidifier unit collects in the water collection tank 111, and then flows directly into the lower cabinet 10 for storage through the inner hole of the drain port 1111. At this time, the drain port 1111 acts as an internal guide channel from the water collection tank 111 to the cabinet 10.

[0067] Continuous drainage mode: When users want to achieve uninterrupted dehumidification for a long time and avoid frequent water emptying, such as... Figure 14 , Figure 15 As shown, one end of an external drain pipe 300 can be passed through the first insertion hole 113 and connected to the drain interface 1111, for example by a socket or screw connection. At this time, the condensate collected in the water collection tank 111 will no longer flow into the box 10, but will be directly guided to the external drain pipe 300 and discharged to the designated drain position.

[0068] Through the above structural design, the cover 13 of this embodiment integrates the external drainage function into the cover 13, which is most frequently touched and easiest to operate by the user. The user does not need to move the machine to find and connect the drainage interface on the back or inside of the machine, which improves the ease of use and flexibility of the product.

[0069] In some embodiments, to reduce the noise generated when condensate enters the housing 10, a buffer water tank 134 is provided at the bottom of the cover 13 corresponding to the drain port 1111. The buffer water tank 134 has a guide surface 1341 that slopes inward toward the inside of the housing 10. The lower part of the guide surface 1341 is close to the inner wall adjacent to the housing 10. The guide surface 1341 is used to receive the water flow discharged from the drain port 1111 and guide the water flow to slide smoothly into the housing 10 along its surface, so as to achieve the effect of buffering the water flow and reducing dripping noise.

[0070] In some embodiments, such as Figure 2 , Figure 14 , Figure 15As shown, there is a gap between the outer peripheral wall of the drain interface 1111 and the inner peripheral wall of the first insertion hole 113, forming an annular groove suitable for locking the external drain pipe 300 between the outer peripheral wall of the drain interface 1111 and the inner peripheral wall of the first insertion hole 113. Specifically, the annular groove is an annular space formed by the difference between the outer diameter of the drain interface 1111 and the inner diameter of the first insertion hole 113. When the external drain pipe 300 with a certain elasticity is sleeved on the drain interface 1111, the end of the external drain pipe 300 can be further pushed in, so that part of its pipe wall is squeezed and embedded in the annular groove. This structure uses the annular groove to effectively hold and limit the end of the external drain pipe 300, preventing the external drain pipe 300 from slipping due to accidental dragging without any additional fasteners, thus ensuring the reliability of continuous drainage.

[0071] In some embodiments, such as Figure 18 , Figure 19 As shown, to meet the user's need to discharge condensate upwards or over long distances, a water pump (not shown) is also installed inside the housing 10, and the water pump is connected to a water pump drain pipe. Correspondingly, a second insertion hole 114 is provided on the side wall on the front side of the boss 112, and the outlet of the water pump drain pipe is connected to the second insertion hole 114. With this design, the water pump can actively draw the condensate collected inside the housing 10 to the outside through the second insertion hole 114.

[0072] Furthermore, in order to keep the water tank's appearance clean and prevent dust from entering or moisture from overflowing when draining without using an external drain pipe and pump, such as Figure 19 , Figure 21 As shown, a soft rubber plug 92 is provided on the side wall of the front side of the boss 112 and the raised portion 11. Specifically, the back of the soft rubber plug 92 is provided with a first plug 921 adapted to and used to seal the first socket 113, and a second plug 922 adapted to and used to seal the second socket 114. When in the normal water storage mode, the first plug 921 and the second plug 922 respectively tightly seal the first socket 113 and the second socket 114.

[0073] To prevent the soft rubber stopper 92 from being accidentally lost after being pulled out, such as Figure 21 , Figure 22As shown, a fixing hole 115 is provided on the side wall of the front side of the boss 112 in the area between the first insertion hole 113 and the second insertion hole 114. The fixing hole 115 is located in the middle of the first insertion hole 113 and the second insertion hole 114, and the fixing hole 115, the first insertion hole 113, and the second insertion hole 114 are arranged in a straight line with intervals. Correspondingly, a flexible insertion post 923 is integrally formed on the back of the soft rubber stopper 92 at the position of the fixing hole 115. An anti-retraction protrusion ring 924 is protruding on the outer periphery of the insertion post 923. The diameter of the anti-retraction protrusion ring 924 gradually decreases from the direction close to the soft rubber stopper 92 to the direction far away from the soft rubber stopper 92, that is, it is conical or barbed. During assembly, the insertion post 923 is pressed through the fixing hole 115, and the anti-retraction protrusion ring 924 rebounds after passing through the fixing hole 115. The anti-retraction protrusion ring 924 is used to lock the insertion post 923 inside the fixing hole 115, thereby preventing the soft rubber plug 92 from falling off the boss 112. When the user needs to connect an external drain pipe, he / she only needs to pull out the first plug post 921 or the second plug post 922. The soft rubber plug 92 as a whole is still suspended at the fixing hole 115 by the insertion post 923, thus preventing loss. The soft rubber plug 92 has lugs on the front of both ends along its length. The lugs are perpendicular to the front of the soft rubber plug 92. The user can pull out the corresponding plug post by applying force outward to the lugs, thereby exposing the corresponding insertion hole, which is convenient for connecting the external drain pipe to the corresponding drain outlet.

[0074] In some embodiments, such as Figure 4 , Figure 7 , Figure 9 As shown, a drain valve 205 is provided on the water receiving tray 203. The drain valve 205 is located in the drain outlet 2031 of the water receiving trough 111. The drain valve 205 can be designed to automatically close under its own weight or the action of an elastic element when no external force is applied, thereby blocking the drain outlet 2031. Correspondingly, a protruding contact 1112 is provided in the water receiving trough 111 at the position corresponding to the drain valve 205. The protruding contact 1112 is configured to press and open the drain valve 205 to open the drain outlet 2031 when the water tank 100 is inserted into the receiving cavity 201. When the water tank 100 is removed from the receiving cavity 201, the protruding contact 1112 separates from the drain valve 205, and the drain valve 205 closes the drain outlet 2031.

[0075] Specifically, the drain valve 205 includes a valve stem 2051, an elastic seal 2052 fixed to the top of the valve stem 2051, and a spring 2053 sleeved on the valve stem 2051. The bottom end of the valve stem 2051 has a circular head 2054, and one end of the spring 2053 abuts against the head 2054. The spring 2053 keeps the valve stem 2051 moving downward. The elastic seal 2052 can adopt a trumpet-shaped structure that is wider at the top and narrower at the bottom, or a spherical or hemispherical structure, and its outer surface is in sealing contact with the opening edge of the drain outlet 2031. Figure 4 , Figure 7As shown, when the user pushes the water tank 100 into the receiving cavity 201 of the body 204, the protruding contact 1112 located in the water receiving groove 111 will gradually approach and eventually contact the drain valve 205 as the water tank goes deeper. During this process, the protruding contact 1112 will contact the head 2054 to generate an upward pushing force on the valve stem 2051, so that the valve stem 2051 overcomes the spring force of the spring 2053, thereby pushing open the elastic seal 2052. At this time, the drain outlet 2031 is fully opened, and the condensate generated on the heat exchanger drips into the water receiving tray 203 and can then flow smoothly into the water receiving groove 111 of the water tank 100 through the opened drain outlet 2031.

[0076] When the user needs to empty the water tank 100 and pulls it out of the receiving cavity 201, the protruding contact 1112 moves outward and separates from the drain valve 205. The moment the pushing force of the protruding contact 1112 disappears, the drain valve 205 immediately resets automatically under the action of the spring force, quickly and tightly closing the drain outlet 2031. This closing action is completed before the water tank 100 is completely removed from the machine body. This fundamentally solves the persistent problem in existing technologies where residual condensate continuously drips and wets the inside of the machine or the floor, effectively improving the cleanliness and convenience for users.

[0077] In some embodiments, such as Figure 10 , Figure 13 , Figure 16 As shown, the top surface of the flip cover 132 is not a flat surface, but is designed as a recessed area with a gentle slope 1324. A drain hole 1326 is provided at the lowest point where the recessed area and the abutment edge 1325 of the periphery of the flip cover 132 are enclosed. The abutment edge 1325 rests against the opening edge of the top of the box body 10. When the drain hole 1326 is placed on a horizontal surface such as the ground, liquid that accidentally splashes or condenses on the cover 13 in the drain outlet 2031 will automatically flow into the recessed area due to gravity and quickly drain into the box body 10 through the drain hole 1326 at the lowest point.

[0078] In some embodiments, such as Figure 5 , Figure 8 , Figure 11 , Figure 13 As shown, the handle 20 is not pivotally connected to the lid 13 directly, but rather through a separate connecting block 60. Specifically, a connecting block 60 is pre-installed on the box 10, and the upper end of the connecting block 60 has an exposed portion 61 that passes through the lid 13. The handle 20 is pivotally connected to this exposed portion 61. This split design simplifies the mold for the box 10, allowing for a smooth and seamless appearance on its outer surface.

[0079] In this embodiment, the outer wall of the housing 10 is recessed inward to form a mounting groove 121. A partition 122 is provided near the top of the mounting groove 121, and the partition 122 has an assembly hole 123. Correspondingly, the connecting block 60 includes a base 62 and a mounting block 63 connected to the top surface of the base 62. The mounting block 63 has anti-retraction portions 64 protruding on both sides along its length, and the mounting block 63 abuts against the bottom surface of the partition 122. One end of the mounting block 63 passes through the assembly hole 123 and the cover 13 to form an exposed portion 61. The width of the cross-section of the anti-retraction portion 64 gradually increases from top to bottom, and the partition 122 is engaged between the anti-retraction portion 64 and the mounting block 63. During assembly, the mounting block 63 passes through the mounting hole 123 from bottom to top. The structure of the cross-sectional width of its retaining part 64 gradually increasing from top to bottom ensures that after the mounting block 63 passes through, the partition 122 is firmly snapped between the retaining part 64 and the mounting block 63, thereby achieving quick and stable installation of the connecting block 60. In addition, the water tank 100 is assembled from multiple parts and does not require screws.

[0080] Furthermore, the connecting block 60 has two strip holes 65, which makes it easier for the connecting block 60 to deform when squeezed, thus facilitating the connecting block 60 to pass through the partition 122 for snap-fit ​​installation; and the top of the connecting block 60 is set to be arc-shaped, which facilitates the operation of inserting the mounting block 63 into the assembly hole 123.

[0081] The dehumidifier water tank and dehumidifier provided in this application embodiment integrate unlocking and pulling actions by setting a spring-loaded buckle structure between the handle or cover and the top wall of the receiving cavity. Users can unlock and pull out the water tank by pulling the handle upwards while standing, eliminating the need to bend over and saving effort. After the water tank is removed, the buckle is hidden at the top, improving the product's aesthetics. Furthermore, the gravity-flipping cover allows for easy emptying, and the integrated soft rubber stopper and water pump interface solution balances the convenience of multi-mode drainage with a clean appearance.
