Description

Technical Field

[0001] This utility model relates to the technical field of household dehumidifiers, and in particular to a drainage structure for a dehumidifier housing and a dehumidifier thereof. Background Technology

[0002] A dehumidifier consists of components such as a compressor, evaporator, condenser, fan, water tank, and humidity control system. Its working principle is as follows: When humid air is drawn in by the fan and passes through the evaporator, the water vapor in the air condenses into liquid water and drips into the water tank because the surface temperature of the evaporator is lower than the dew point temperature of the air. At the same time, the cooled and dried air then flows through the higher-temperature condenser, absorbs the heat released by the condenser, and its temperature rises but its humidity decreases. Finally, it is discharged in a relatively dry and warm state, thus completing the dehumidification cycle.

[0003] In existing technology, dehumidifiers employ different dehumidification modes depending on the environment, generally categorized into two common modes: continuous dehumidification and automatic dehumidification. Continuous dehumidification requires constant operation, thus continuously producing condensate, which must be automatically drained from the machine via an external drain pipe. Automatic dehumidification automatically stops operating when humidity is low. Therefore, it often involves collecting condensate in a water tank, and then manually draining the water once the set level is reached, after which the machine continues operating. Continuous drainage is more suitable for fixed locations and high-humidity environments, while automatic drainage is better suited for scenarios requiring flexible movement. Both of these drainage methods involve complex processes, and dehumidifiers with automatic drainage functions have complex structures. Furthermore, the operation required to switch from manual to automatic drainage is complex, causing considerable inconvenience to users.

[0004] For example, patent publication number CN108981129A, invention titled "Dehumidifier with Automatic Drainage", includes a dehumidifier body, a water tank, a controller, and an automatic drainage structure. In the drainage method, the automatic drainage structure includes a water pump, a drain pipe, and a liquid level sensor. The outlet end of the drain pipe is connected to the water pump. The automatic drainage structure also includes a conduit assembly, which includes a fixed conduit. The drain pipe body passes through the fixed conduit along its axial direction and is installed inside the fixed conduit. The inlet end of the drain pipe passes through the fixed conduit and extends into the water tank through the tank opening. The fixed conduit is fixed to the dehumidifier body. The automatic drainage structure can drain water automatically, and the drain pipe is supported and guided by the conduit assembly. Therefore, there is no connection between the inlet end of the drain pipe and the water tank.

[0005] Therefore, in dehumidifiers with automatic drainage, condensate first collects in a water tank, which is equipped with a drain pump. Turning on the pump drains the liquid from the tank. However, the connection and disconnection of the drain pipes between the water tank and the drain pump is often complex, and the installation of the drain connector is cumbersome and inconvenient. Furthermore, the process of switching from manual to automatic drainage is complicated, and leakage at the drain outlet cannot be effectively prevented. After installation, the drain connector is prone to accidental detachment due to external forces, causing considerable inconvenience to users. There is an urgent need for new technological inventions to solve these problems. Utility Model Content

[0006] This utility model provides a drainage structure for a dehumidifier box and a dehumidifier thereof. The water outlet hose is easy to disassemble, which facilitates the collection of condensate through the water tank and direct drainage through the water pipe. At the same time, it effectively prevents the drain joint from falling off due to external pulling, significantly improving the reliability and safety of use.

[0007] The technical solution adopted by this utility model to solve its technical problem is: A drainage structure for a dehumidifier includes a dehumidifier water tank and a base frame. The top of the base frame is provided with a water receiving tray for receiving and collecting condensate. The dehumidifier water tank is slidably inserted into the base frame below the water receiving tray and moves back and forth laterally. It is used to store the condensate draining from the water receiving tray and the condensate drained after the dehumidifier water tank is manually disassembled. The base frame on the bottom side of the dehumidification water tank is also provided with a drain interface for the condensate collected by the water receiving tray to be discharged directly. A connecting rib plate located in the middle of the base frame is provided between the water receiving tray and the lower drainage interface, forming a drainage channel for condensate to drain directly vertically. A flexible water outlet hose, extending from the bottom of the dehumidification tank, is inserted and connected to the drain interface for draining water outwards.

[0008] Preferably, the water receiving tray is also equipped with a water pump to facilitate the automatic discharge of condensate from the drainage channel.

[0009] Preferably, the drain interface is further provided with an interface self-locking component that automatically closes the entire drain channel when the water outlet hose is pulled out from the connector, or automatically opens the entire drain channel when the water outlet hose is inserted and connected. The interface self-locking assembly includes a tapered connecting sleeve, a T-type stop valve arranged along the channel axis, a self-locking tension spring, and an O-ring seal. The tapered connecting sleeve is sealed in the drain connector sleeve provided at the end of the drainage channel. The T-type stop valve has at least one guide groove along its axial outer edge to facilitate the flow of condensate into the outlet hose after the drainage channel is opened. The self-locking tension spring is fitted onto the axial section of the T-type stop valve and is slidably inserted into the guide channel at the center of the tapered joint sleeve. The O-ring is fitted into the circumferential groove at the other end of the T-type shut-off valve, which is opposite to the axial lateral movement of the self-locking tension spring. Under the self-tensioning action of the self-locking tension spring, the T-type shut-off valve synchronously drives the O-ring to move laterally and closes the conical funnel opening recessed at the inner end of the conical joint sleeve, preventing condensate from leaking out of the drainage channel. When the outlet hose is inserted and connected, the T-type shut-off valve and the O-ring are pushed and synchronously moved inward to open the conical funnel opening of the conical joint sleeve. Then, the condensate in the entire drainage channel is automatically guided into the outlet hose along the guide groove on the circumferential outer edge of the T-type shut-off valve and discharged.

[0010] Preferably, the outlet hose connection end is also fitted with a flow guide pipe whose top end contacts the T-shaped shut-off valve on the interface self-locking assembly. The top end of the flow guide pipe is recessed with a U-shaped groove to facilitate increasing the flow rate of condensate in the conical connection sleeve into the outlet hose.

[0011] Preferably, a locking groove is provided on the side of the flow guide pipe on the base frame located on the bottom side of the dehumidification water tank to prevent the flow guide pipe and the water outlet hose from disengaging. The rear end of the flow guide pipe extends radially outward to have a connector handle for deflecting at a certain angle in the circumferential direction and locking into the locking groove.

[0012] Preferably, the connector handle is also equipped with a magnetic block for activating the side-mounted induction switch and simultaneously controlling the water pump on the water receiving tray to automatically discharge condensate from the drainage channel.

[0013] A dehumidifier includes a housing, and the water tank trough on the front side of the housing is provided with the aforementioned drainage structure for the dehumidification housing.

[0014] The beneficial effects of this utility model are: The drain interface is fitted with a flexible water outlet hose that extends from the bottom of the dehumidifying water tank for draining water. The drain interface is also equipped with a self-locking component that automatically closes the entire drain channel when the flexible water outlet hose is pulled out of the connector, or automatically opens the entire drain channel when the flexible water outlet hose is inserted and connected. The entire drainage structure facilitates the collection of condensate water through the dehumidifying water tank and allows for direct drainage through the water pipe.

[0015] Furthermore, the base frame on the bottom side of the dehumidification tank next to the flow guide pipe on the outlet hose is equipped with a locking groove to prevent the flow guide pipe and outlet hose from disengaging. The corresponding flow guide pipe has a connector handle that extends radially outward at the rear end and is used to deflect at a certain angle in the circumferential direction and lock into the locking groove. This gives the entire outlet hose a self-locking function after installation, which can effectively prevent the drain connector from falling off due to external pulling, and significantly improve the reliability and safety of use.

[0022] A drainage structure for a dehumidifier box, such as Figures 1 to 9As shown, a water tank trough 2 is installed on the front side of the upper housing 1 of the dehumidifier for automatic drainage; it includes a dehumidifying water tank 3 and a base frame 4. A drip tray 5, integrally formed at the top of the base frame 4, is used to receive and collect condensate. The dehumidifying water tank 3 is slidably inserted into the base frame 4 below the drip tray 5, moving laterally back and forth, to store the condensate draining from the drip tray 5 and to discharge condensate after manual disassembly of the dehumidifying water tank 3. A drain interface 6 is also provided on the base frame 4 at the bottom of the dehumidifying water tank 3 for direct discharge of the condensate collected by the drip tray 5. The drip tray 5 and the lower drain... A connecting rib plate 40 located in the middle of the base frame 4 is provided between the water inlets 6, forming a drainage channel 41 for condensate to drain directly vertically. A water pump 7 is also provided on the water receiving tray 5 to facilitate the automatic discharge of condensate from the drainage channel 41. A water outlet hose 8 is inserted and connected to the drain inlet 6, which is led out from the bottom side of the dehumidification water tank 3 for draining water. A self-locking component 9 is also provided at the drain inlet 6, which automatically locks the entire drainage channel 41 when the water outlet hose 8 is pulled out from the joint, or automatically opens the entire drainage channel 41 when the water outlet hose 8 is inserted and connected.

[0023] Continue as Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the self-locking assembly 9 includes a tapered connecting sleeve 90, a T-type shut-off valve 91 arranged axially along the channel, a self-locking tension spring 92, and an O-ring seal 93. The tapered connecting sleeve 90 is sealed and fitted into the drain connector sleeve 10 at the end of the drain channel 41. The T-type shut-off valve 91 has four evenly distributed guide grooves 11 along its axial outer edge to facilitate the flow of condensate into the outlet hose 8 after the drain channel is opened. The self-locking tension spring 92 is fitted into the axial section of the T-type shut-off valve 91 and slidably inserted into the guide channel at the center of the tapered connecting sleeve 90. The O-ring seal 93 is fitted onto the T-type shut-off valve 91. In the circumferential groove 12 at the other end of the thrust self-locking tension spring 92, under the self-tensioning action of the self-locking tension spring 92, the T-type stop valve 91 synchronously drives the O-ring seal 93 to move laterally and closes the conical funnel opening 13 recessed at the inner end of the conical docking sleeve 90, preventing condensate from leaking out of the drainage channel; when the outlet hose 8 is inserted and connected, the T-type stop valve 91 and the O-ring seal 93 are pushed and moved laterally inward to open the conical funnel opening 13 of the conical docking sleeve 90. After this, the condensate in the entire drainage channel 41 is automatically guided into the outlet hose 8 along the guide groove 11 on the outer circumferential edge of the T-type stop valve 91 and discharged.

[0024] like Figures 3 to 9As shown, the outlet hose 8 is also fitted with a flow guide pipe 14 at its end, which contacts the T-shaped shut-off valve 91 on the interface self-locking assembly 9. The top of the flow guide pipe 14 is recessed with a U-shaped groove 140 to facilitate increasing the flow rate of condensate in the conical connecting sleeve 90 into the outlet hose 8. A locking groove 15 is also provided on the base frame 4 located on the bottom side of the dehumidification tank 3 to prevent the flow guide pipe and the outlet hose 8 from disengaging. The rear end of the flow guide pipe 14 extends radially outward with a connector handle 16 for deflecting at a certain angle in the circumferential direction and locking into the locking groove 15. Moreover, when the dehumidification tank 3 is inserted into the housing 1, the dehumidification tank 3 can further limit and lock the connector handle 16. In addition, a magnet block 17 is also installed at the connector handle 16 to activate the induction switch on the side base frame 4 and simultaneously control the water pump 7 on the water receiving tray 5 to automatically discharge condensate from the drainage channel.

[0025] In this embodiment, when the user needs to use the dehumidifier's water pump 7 function, the dehumidifier water tank 3 needs to be removed. Then, the guide connector 14 at the end of the outlet hose 8 is inserted into the interface self-locking assembly 9. The connector handle 16 is rotated counterclockwise until it is locked in the locking groove 15. The dehumidifier water tank 3 is then repositioned. The limiting structure at the bottom of the dehumidifier water tank 3 interlocks the dehumidifier water tank 3 and the guide connector 14, preventing the user from directly removing the guide connector 14 and significantly reducing the risk of the connector being accidentally pulled off during use. When the user stops using the guide connector 14 and the outlet hose 8, the dehumidifier water tank 3 needs to be removed. Then, the connector handle 16 is rotated clockwise to remove the outlet hose 8 and the guide connector 14, and the dehumidifier water tank 3 is then reinstalled.

[0026] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. All equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
