[0035] A dehumidifier is an air handling device that reduces air humidity through physical or chemical means. It is mainly used to improve indoor air quality, prevent health problems caused by dampness, and protect items from moisture damage. Its core function is to extract moisture from the air through condensation, adsorption, or ion exchange and then return the dry air to the environment, thereby maintaining a suitable humidity range.

[0036] There are many types of dehumidifiers, which can be classified in different ways. Based on their working principle, they are typically categorized into condenser dehumidifiers, rotary dehumidifiers, and solution dehumidifiers. Condenser dehumidifiers cool the air and dehumidify it through an evaporator, and are one of the most common types on the market. Rotary dehumidifiers use a desiccant on a rotating wheel to absorb moisture from the air, making them suitable for large spaces. Solution dehumidifiers absorb moisture from the air using a solution, offering high efficiency and reliable operation. Based on their application scenario, they are typically categorized into household dehumidifiers, commercial dehumidifiers, and industrial dehumidifiers. Household dehumidifiers are suitable for home environments, are usually small in size, and easy to operate. Commercial dehumidifiers are suitable for larger spaces such as offices and warehouses, and offer more powerful functions. Industrial dehumidifiers are suitable for industrial environments such as factories and basements, and have stronger dehumidification capabilities and adaptability.

[0037] A condensing dehumidifier, operating on the same principle as a condenser dehumidifier, mainly consists of a casing, a heat pump system housed within the casing, and a drainage system. Its working principle is as follows: a compressor drives a refrigerant circulation (e.g., compressor-condenser-capillary tube-evaporator), causing the evaporator surface temperature to drop below the air dew point temperature. When humid air flows through the cold evaporator, the water vapor in the air condenses into liquid water due to the temperature difference. This process is similar to the dehumidification stage of air conditioning, but the dehumidifier specifically enhances the dehumidification function, resulting in the production of a large amount of condensate.

[0038] Generally, a drainage system typically includes a drip tray and a water tank. The drip tray collects water droplets from the evaporator surface and transfers them to the water tank. When the water in the tank reaches a certain level, it usually needs to be drained. In home environments, users need to periodically empty the water tank, which is one of the drainage methods for dehumidifiers. However, in existing technologies, dehumidifiers either have a water outlet directly on the cover or a manually operated fixed cover on the outlet. With a direct water outlet, manually emptying the tank when it's full may cause water to splash out. With a fixed cover, users need to open and close the cover themselves to empty the water, which is inconvenient. Furthermore, after prolonged use, the cover may become dirty, making users reluctant to touch it, resulting in a poor user experience.

[0039] Since a dehumidifier is also a type of air handling device, and a water tank can also be used for other water tank control and handling devices besides a dehumidifier, such as a portable air conditioner with dehumidification function; therefore, for ease of description, air handling devices will be another subject of this application below.

[0040] This application discloses a water tank and an air handling device, aiming to improve the convenience of emptying the water tank or the convenience of cleaning accumulated water from the air handling device. For ease of understanding and explanation, details are attached to the specification of this application. Figures 1 to 4In the diagram, the arrowhead indicates a face, opening, or hole.

[0041] Please see Figures 1 to 4 In one embodiment of this application, the water tank 10 includes a tank body 100 and a drain cover 200. The tank body 100 is provided with a drain outlet 101. The drain cover 200 is rotatably disposed on the tank body 100 and includes a rotating connector 230, a cover body 210 and a counterweight 220. The rotating connector 230 is rotatably connected to the tank body 100 and has a first end and a second end located on opposite sides of the connection between the rotating connector 230 and the tank body 100. The cover body 210 is disposed on the first end of the rotating connector 230 and is used to open or close the drain outlet 101. The counterweight 220 is disposed on the second end of the rotating connector 230. When the tank body 100 is in an inclined state, the cover body 210 can open the drain outlet 101 under the action of the counterweight 220.

[0042] The following will take the application of water tank 10 in air handling unit 1 as an example.

[0043] Air handling unit 1 includes a main body 20 and a water tank 10 detachably disposed from the main body 20. The water tank 10 is used to collect condensate generated by the main body 20. The air handling unit 1 typically includes a housing, a heat pump system, an air circulation system, a control system, and a drainage system disposed on the housing. Generally, the housing serves as the mounting base for the unit, and the housing provides installation space for the heat pump system, air circulation system, and control system. The housing also provides air ducts for the air circulation system. The heat pump system includes refrigeration cycle components such as a compressor, evaporator, condenser, and capillary tube, which are responsible for completing the cooling and dehumidification process of the air. The air circulation system includes a built-in fan and filter, which drives humid air to be drawn in and dry air to be discharged. The control system integrates a humidity sensor, control circuit board, and operating interface to realize operation mode adjustment and water level monitoring. The drainage system typically includes a drip tray and a water tank 10. The drip tray is used to collect water droplets on the surface of the evaporator and transport them to the water tank 10.

[0044] The main body 20 refers to all necessary components other than the water tank 10 of the drainage system.

[0045] The water tank 10 is a container used to collect condensate generated by the main body 20 of the device. The water tank 10 is detachable from the main body 20; that is, the water tank 10 is an independent container that can be physically separated from the main body 20. The water tank 10 can be detachably installed on the main body 20, or it can be unconnected to the main body 20. The water tank 10 is placed below the drip tray and is sufficient to collect the condensate generated by the main body 20. Taking the detachable installation of the water tank 10 and the main body 20 as an example, it is connected to them via an interface and is specifically used for collecting, temporarily storing, and transferring condensate generated by the refrigeration cycle. The water tank 10 can have various shapes, including regular shapes such as cylindrical, elliptical, or rectangular, as well as other irregular shapes, such as flat or rectangular. Figure 2 The irregular shape shown.

[0046] The housing 100 is the main structure of the water tank 10, which constitutes a space for temporarily storing and transferring water. The housing 100 is also provided with a water inlet 102 for collecting condensate and a drain outlet 101 for discharging condensate. The housing 100 can be integrally formed (e.g., blow-molded or 3D printed) or it can be set in parts, and no specific limitation is made here.

[0047] The drain outlet 101 is a structure installed in the tank 100. In order to ensure the water storage capacity of the water tank 10 and reduce the liquid spillage in the water tank 10, the drain outlet 101 is usually installed at the top of the tank 100. For example, it can be the halfway line of the height of the water tank 10, or it can be the two-thirds, three-fifths or four-fifths line of the water tank 10 from bottom to top as the dividing line, and the drain outlet 101 is installed above the dividing line; preferably, the drain outlet 101 is installed at the top of the water tank 10.

[0048] A drain cover 200 is a component used to open or close the drain outlet 101. The part of the drain cover 200 used for closing is adapted to the shape of the drain outlet 101. The drain cover 200 is rotatably mounted on the housing 100, wherein the drain cover 200 and the housing 100 can be hinged or pivotally connected by a pivot, etc.

[0049] When the housing 100 is tilted, the cover 210 can open the drain outlet 101 under the action of the counterweight 220. The tilting state of the housing 100 is relative to its flat position. Generally speaking, the tilting state of the housing 100 can be as follows: Figure 5 The diagram shows one embodiment; in other embodiments, the tilt angle of the housing 100 may be different from that shown. Figure 5 (Different from what is shown), the box 100 in its flat position, such as Figure 1 The water tank 100 is shown.

[0050] Furthermore, the drain cover 200 can rotate relative to the tank 100 as the tilt angle changes, thereby controlling the size of the drain outlet 101. In other words, the tank 100 and the drain cover 200 are linked. When the tank 100 switches from a flat position to a tilted position, within at least a certain rotation angle range, the larger the tilt angle of the tank 100, the larger the rotation angle of the drain cover 200 relative to the tank 100, and the larger the effective flow area of ​​the drain outlet 101. When the tank 100 rotates from the tilted position to the flat position, it is the reset process of the tank 100 switching from the flat position to the tilted position, which will not be described in detail here. Controlling the size of the drain outlet 101 can be fully open or fully closed, and in some embodiments, it can also be a region between fully open and fully closed.

[0051] The linkage between the tank body 100 and the drain cover 200 can be achieved in the following ways: First, the drain cover 200 is pivotally connected to the edge of the drain outlet 101. The drain cover 200 is configured to generate adaptive rotational motion as the tilt angle of the tank body 100 changes. The effective flow area of ​​the drain outlet 101 is adjusted by the dynamic coordination between the deflection angle of the cover 210 and the tilt angle of the tank body 100. This solution is generally suitable for situations where the drain outlet is located on the side of the water tank. Second, a rigid component and a counterweight 220 are provided between the tank body 100 and the drain cover 200. When the tank body 100 tilts, the rigid component is driven by the gravity of the counterweight 220, pushing the drain cover 200 to rotate around the pivot. Of course, other implementation methods are also possible, which will not be listed here.

[0052] The technical solution of this application rotatably mounts the water pouring cover 200 onto the tank body 100, and there is a linkage between the water pouring cover 200 and the tank body 100. When the user separates the water tank 10 from the main body 20 of the device and the tank body 100 is in an inclined state, the cover 210 can open the water pouring outlet 101 under the action of the counterweight 220. Thus, the technical solution of this application does not require manual opening of the water pouring cover 200, which improves the convenience of pouring water from the water tank.

[0053] When the user tilts the water tank 10 to pour water, the pouring cover 200 can change with the tilt angle of the tank 100 and rotate relative to the tank 100, so that the pouring spout 101 can switch from the closed state to the open state, and the water in the tank 100 can come out through the pouring spout 101; thus, the technical solution of this application does not require manual opening of the cover, which improves the convenience of cleaning up water in the air handling device 1.

[0054] In some embodiments, please refer to Figure 4The water outlet cover 200 includes a cover body 210, a rotating connector 230, and a counterweight 220. The cover body 210 is used to open or close the water outlet 101. The rotating connector 230 is rotatably connected to the housing 100 and has a first end and a second end located on opposite sides of the connection between the rotating connector 230 and the housing 100. The cover body 210 is located at the first end of the rotating connector 230, and the counterweight 220 is located at the second end of the rotating connector 230. When the tilt angle of the housing 100 changes, the counterweight 220 rotates towards the housing 100 under the action of gravity, thereby causing the cover body 210 to rotate away from the housing 100; or the counterweight 220 rotates away from the housing 100 under the action of gravity, thereby causing the cover body 210 to rotate towards the housing 100.

[0055] The cover 210 is the part of the drain cover 200 used to cover the drain spout 101. The counterweight 220 can be a counterweight block, counterweight ball, or counterweight bar, etc. Preferably, the counterweight 220 is a counterweight ball, so that when the counterweight block rotates and impacts the housing 100, damage to the housing 100 can be reduced. The rotating connector 230 is rotatably connected to the housing 100, forming a rotation fulcrum. The cover 210 and the counterweight 220 are respectively located on opposite sides of the connection between the rotating connector 230 and the housing 100, forming a lever structure to achieve force transmission.

[0056] In this embodiment, using the lever principle, taking the opening process as an example, when the user tilts the water tank 10 to pour water, the tilt angle of the tank 100 relative to the horizontal plane usually gradually increases. At this time, the counterweight 220 swings downward (towards the tank 100) due to gravity. The gravitational torque of the counterweight 220 drives the lid 210 to move in the opposite direction, realizing the synchronous and reverse linkage between the lid 210 and the tank 100, thus completing the automatic opening action. In addition, during the closing process, the counterweight 220 rotates away from the tank 100 under the action of gravity, which in turn drives the lid 210 to rotate closer to the tank 100. The linkage between the tank 100, the counterweight 220, and the lid 210 forms an "open-close" closed loop. The user only needs to control the tilting action of the tank 100 without intervening in the switch operation, further improving the user experience.

[0057] In some embodiments, please refer to Figure 3 and Figure 4The rotating connector 230 includes a rotating rod 231 and a connecting rod 232 disposed on the rotating rod 231. The rotating rod 231 extends along a first direction, and the connecting rod 232 extends along a second direction. The first direction and the second direction are arranged at an angle. The two ends of the rotating rod 231 are rotatably connected to the housing 100. The connecting rod 232 has two ends located on opposite sides of the connection between the connecting rod 232 and the housing 100. The cover 210 is disposed at one end of the connecting rod 232, and the counterweight 220 is disposed at the other end of the connecting rod 232.

[0058] The rotating rod 231 serves as the rotation axis, providing rotational freedom. At the same time, it forms a stable rotational support structure by connecting to the housing 100 at both ends. The rotating rod 231 is rotatably connected to the housing 100 at both ends. The double-support design enhances structural stability and reduces off-center wear compared to single-sided support.

[0059] The connecting rod 232 is provided on the rotating rod 231. The connecting rod 232 constitutes the lever arm, and its direction forms an angle with the rotating rod 231. It is preferably perpendicular, but it can also be set at a small angle. For example, the angle between the first direction and the second direction is less than 30°. Specifically, it can be 1°, 3°, 5°, 8°, 10°, 12°, 15°, 18°, 20°, 25°, 28° or 30°. The connecting rod 232 converts the opening and closing movement of the cover 210 relative to the box 100 into the rotational movement of the rotating rod 231 relative to the box 100.

[0060] In this embodiment, two rods are used as rotating connectors 230, which results in a simple structure and convenient installation.

[0061] In some embodiments, please refer to Figure 4 The torque at the end where the cover 210 is located is greater than or equal to the torque at the end where the counterweight 220 is located.

[0062] Torque is the product of force and lever arm. In this embodiment, the torque of the end of the cover 210 and the counterweight 220 refers to the torque of gravity. The torque at the end of the cover 210 is equal to the torque at the end of the counterweight 220, which can reduce the instability or imbalance of the drain cover relative to the box 100 during rotation.

[0063] The torque at the end where the cover 210 is located is greater than the torque at the end where the counterweight 220 is located. Generally, this means slightly greater than, for example, the ratio of the torque at the end where the cover 210 is located to the torque at the end where the counterweight 220 is located is 1.01 times, 1.02 times, 1.03 times, 1.04 times, 1.08 times, 1.10 times, 1.15 times, 1.18 times, or 1.20 times, etc.

[0064] Furthermore, the torque at the end of the cover 210 is slightly greater than the torque at the end of the counterweight 220. The torque is the product of the force and the lever arm. Thus, when the cover 210 closes the drain outlet, it can exert a downward force on the cover 210, which can press down the drain outlet 101. This reduces the possibility of water spillage caused by the cover 210 opening the drain outlet 101 due to the shaking of the water tank 10 during transportation.

[0065] In one example, in the first direction, the torque at the end where the cover 210 is located is greater than or equal to the torque at the end where the counterweight 220 is located. In another example, in the second direction, the torque at the end where the cover 210 is located is greater than or equal to the torque at the end where the counterweight 220 is located. In yet another example, in both the first and second directions, the torque at the end where the cover 210 is located is greater than or equal to the torque at the end where the counterweight 220 is located.

[0066] In one exemplary embodiment, please continue to refer to Figure 3 and Figure 4 The connecting rod 232 includes a first rod segment 232a and a second rod segment 232b; one end of the first rod segment 232a is connected to the rotating rod 231 and the other end is connected to the cover 210; one end of the second rod segment 232b is connected to the rotating rod 231 and the other end is connected to the counterweight 220; along the direction from the cover 210 to the counterweight 220, the length of the first rod segment 232a is greater than that of the second rod segment 232b.

[0067] In this embodiment, the length of the first rod segment 232a is greater than that of the second rod segment 232b, so that the torque at the end of the cover 210 is greater than that at the end where the configuration component is located, thereby reducing the possibility of water spillage caused by the cover 210 opening the water outlet 101 due to the shaking of the water tank 10 during the transportation process.

[0068] To facilitate the manufacture of the housing 100, the housing 100 is typically designed as a separate unit; furthermore, in some embodiments, please refer to... Figure 2 The box body 100 includes a box body 110 and a box cover 120. The box body 110 has a receiving cavity 103 with a top opening 104. The box cover 120 covers the opening 104. The box cover 120 is provided with a water pouring part 130, a water pouring port 101 is provided in the water pouring part 130, and a water pouring cover 200 is rotatably provided on the side of the box cover 120 away from the receiving cavity 103.

[0069] In this embodiment, by adopting a split design for the tank 100, it is easier to manufacture the tank 100, and users can also open the lid to clean the internal space of the tank. In addition, by setting the drain outlet 101 on the top cover 120, the water output of the tank 100 can be increased, and the problem of water spillage during the transfer of the water tank 10 can be reduced.

[0070] In some embodiments, the water pouring part 130 protrudes from the outer surface 123 of the tank cover 120, and the water outlet 101 is located on the side of the water pouring part 130 away from the tank cover 120. The technical solution of this embodiment can further increase the water output of the tank 100 and further reduce the problem of water spillage during the transfer of the water tank 10.

[0071] In some embodiments, the cover 120 has two mounting portions 140 on one side away from the body 110, the two mounting portions 140 are spaced apart, and each of the two mounting portions 140 has a mounting hole 141; the rotating connector 230 has a third end and a fourth end opposite to each other, the third end passes through one of the mounting portions 140, the fourth end passes through the other mounting portion 140, and the rotating connector 230 is rotatably connected to the two mounting portions 140 respectively.

[0072] The mounting part 140 is located on the side of the cover 120 away from the body 110, and the two are spaced apart. The double-support design enhances structural stability and reduces eccentric wear compared to single-sided support. This allows the cover 120 to evenly bear the force from the rotating connector 230, thus maintaining balance. Secondly, this arrangement also facilitates the installation of the rotating connector 230 onto the mounting part 140.

[0073] In some embodiments, the lid 120 has a main body 121 and an edge portion 122 surrounding the main body 121, the edge portion 122 being connected to the body 110; a water-pouring portion 130 and two mounting portions 140 are respectively provided on the main body 121, the two mounting portions 140 being located on the side of the water-pouring portion 130 closer to the main body 121.

[0074] Generally, the edge portion 122 is provided with a connection structure with the box body 100, such as a slot or a buckle. By connecting the edge portion 122 with the box body 110, the box cover 120 can achieve good sealing performance, reduce interference from the external environment or leakage of the contents inside the box, and the connection between the edge portion 122 and the box body 100 provides stable support.

[0075] Both the pouring section 130 and the mounting section 140 are located on the main body 121 of the cover 120. The two mounting sections 140 are located on the side of the pouring section 130 closer to the main body 121, making the pouring section 130 convenient for liquid discharge or pouring. The mounting sections 140 are used for connection or support between the cover 120 and other parts of the tank 100. The mounting sections 140 are located adjacent to the pouring section 130 and on the side of the pouring section 130 closer to the main body 121. This not only makes the function of the pouring section 130 more intuitive and convenient, but also ensures the smoothness of opening and closing the pouring cover 200 and the pouring operation.

[0076] In some embodiments, in order to facilitate observation of the water level in the water tank 10, a water level observation window 111 is provided on the periphery of the tank body 110, and the water level observation window 111 extends from the bottom of the tank body 110 to the tank cover 120; the device body 20 has an installation chamber 21 for installing the water tank 10; after the water tank 10 is installed in the installation chamber, the water level observation window 111 is exposed outside the installation chamber 21.

[0077] The main body 20 of the device has a dedicated mounting compartment for installing the water tank 10. This mounting compartment provides a fixed position for securely installing the water tank 10. With this design, a stable connection is formed between the water tank 10 and the main body 20 of the device, and the water tank 10 will not easily fall off or move during use.

[0078] The water level observation window 111 is typically made of a transparent material. Located around the perimeter of the tank body 110, it extends from the bottom of the tank body 110 to the tank cover 120. The main purpose of the observation window 111 is to facilitate user observation of the water level within the water tank 10. Its extension from the bottom of the tank body 110 to the tank cover 120 provides different viewing angles for the water level, making observation more intuitive and convenient. Changes in the water level within the tank 10 can be easily monitored through the observation window without opening the tank cover 120 or performing other complex operations. The installation of the water tank 10 allows the water level observation window 111 to be exposed outside the installation compartment 21, facilitating user observation of the water level through the window.
