Description

Technical Field

[0001] The present invention relates to the field of dehumidifiers, and particularly to a drainage structure and a dehumidifier for a dehumidifier. Background Art

[0002] The structure of a dehumidifier mainly consists of core components such as a compressor, an evaporator (the refrigerant evaporation end), a condenser (the refrigerant condensation end), a capillary tube, a fan, a water storage tank, and a humidity control system. Its working principle is based on the physical process of the refrigeration cycle: when humid air is sucked in by the fan and passes through the evaporator, since the surface temperature of the evaporator is lower than the dew point temperature of the air, the water vapor in the air condenses into liquid water and drips into the water storage tank. At the same time, the cooled and dried air then flows through the condenser with a higher temperature, absorbs the heat released by the condenser, and its temperature rises while the humidity decreases. Finally, it is discharged in a relatively dry and warm state, thus completing the dehumidification cycle. During this process, the compressor drives the refrigerant to circulate in a closed pipeline. The refrigerant vaporizes by absorbing heat in the evaporator and liquefies by releasing heat in the condenser, and the capillary tube is used to achieve throttling and pressure reduction to maintain the system pressure difference.

[0003] Chinese Patent Application CN108981129A discloses a dehumidifier capable of automatic drainage, including a dehumidifier main body, a water tank, a controller, and an automatic drainage structure. The automatic drainage structure includes a water pump, a drainage pipe, and a liquid level sensor. The water outlet end of the drainage pipe is connected to the water pump. The automatic drainage structure further includes a conduit assembly. The conduit assembly includes a fixed conduit. The pipe body of the drainage pipe is axially arranged in the fixed conduit, and the water inlet end of the drainage pipe passes through the fixed conduit and extends into the water tank from the tank opening of the water tank. The fixed conduit is fixed on the dehumidifier main body. The automatic drainage structure can automatically drain water, and the drainage pipe is supported and guided by the conduit assembly. Then, there is no connection relationship between the water inlet end of the drainage pipe and the water tank, and no relevant sealing structure needs to be provided at the water inlet end of the drainage pipe, and there will be no hidden danger of water leakage caused by poor sealing of the sealing structure. Chinese Patent Application CN116085874A discloses a drainage system for a dehumidifier, including a box body, a movable end cover, a dehumidification mechanism, an air inlet and an air outlet. It further includes a drainage assembly. The drainage assembly includes a water receiving tray and a water outlet end, and further includes a water pump for pumping the water receiving tray out from the water outlet end. The water outlet end includes a first water outlet and a second water outlet. The first water outlet is communicated with the water outlet end of the water pump. The water inlet end of the water pump is communicated with the water receiving tray. The second water outlet is communicated with the water receiving tray. The capacity of the water receiving tray is M. When the water volume in the water receiving tray is greater than or equal to 2 / 3M, at this time, the dehumidification mechanism stops dehumidifying. By providing two water outlet ports on the box body, the dehumidifier can realize multi-scenario applications, avoiding the operation of removing the dehumidifier or the water tank to drain water in the prior art. Thus, the dehumidifier can be used in multi-scenarios, and the automatic drainage function of the dehumidifier is realized. The above patents and the prior art also have the following defects: When the water storage tank of the existing dehumidifier is full, the water storage tank needs to be emptied by pouring it. The pouring process is rather troublesome, time-consuming and laborious. A dust-proof net is installed at the air inlet of the dehumidifier. The dust-proof net will become blocked after working for a long time, and it is rather troublesome to clean. Moreover, the dust-proof net is fixed on the housing. Cleaning the dust-proof net from the front easily causes dust to move into the holes of the dust-proof net, blocking the dust-proof net and resulting in poor cleaning effect. The directly poured condensed water is not easy to be reused, leading to waste of resources.

[0021] Embodiment 1: Refer to Figure 1-10 A dehumidifier drainage structure as shown, which includes a dehumidification housing 1, a water storage tank 2, a drainage seat 3, and a dust-proof net 5. The water storage tank 2 and the dust-proof net 5 are arranged on the dehumidification housing 1. A drainage component 4 is arranged at the bottom of the water storage tank 2. A drainage hole is opened at the bottom of the water storage tank 2. The drainage component 4 includes a drainage valve plate 41. The drainage valve plate 41 is located on the drainage hole of the water storage tank 2. A drainage strip 6 is arranged on the drainage seat 3. When the dehumidification housing 1 is moved onto the drainage seat 3, the drainage strip 6 can push the drainage valve plate 41 on the drainage hole upwards; The dust-proof net 5 can be moved from the dehumidification housing 1 into the drainage seat 3. A cleaning component 7 is arranged on the drainage seat 3. The cleaning component 7 includes a cleaning shell 71, a cleaning plate 72, and a cleaning pipe 73. The cleaning pipe 73 is arranged on the cleaning plate 72. After the dust-proof net 5 is moved into the drainage seat 3, the cleaning plate 72 can be moved to the back of the dust-proof net 5. A cleaning groove is opened at the bottom of the cleaning shell 71. The condensed water in the water storage tank 2 can fall into the cleaning groove through the drainage hole. The water in the cleaning groove can be sprayed onto the dust-proof net 5 through the cleaning pipe 73.

[0022] Place the drainage seat 3 at a position with drainage conditions, and place the dehumidification housing 1 at a humid position. The dehumidification housing 1 introduces humid air, condenses and dehumidifies the air and then discharges it. The discharged condensed water falls into the water storage tank 2. When the water in the water storage tank 2 is full, move the dehumidification housing 1 onto the drainage seat 3. During the process of moving onto the drainage seat 3, the drainage strip 6 pushes the drainage valve plate 41 in the water storage tank 2 to rise, and the drainage valve plate 41 disengages from the drainage hole. The water in the water storage tank 2 flows into the cleaning groove on the drainage seat 3. After the dehumidification housing 1 is moved onto the drainage seat 3, the dust-proof net 5 on the dehumidification housing 1 is moved into the drainage seat 3, and the cleaning plate 72 on the drainage seat 3 is moved to the back of the dust-proof net 5. The drainage seat 3 passes water into the cleaning pipe 73 on the cleaning plate 72 and sprays it onto the dust-proof net 5 through the cleaning pipe 73, and the sprayed water is drained away.

[0023] By arranging the drainage seat 3 with drainage conditions, when the water in the water storage tank 2 is full and the dehumidification housing 1 is moved onto the drainage seat 3, the condensed water in the water storage tank 2 can be drained away, saving the step of pouring the water storage tank 2. The drainage is started by moving the dehumidification housing 1 onto the drainage seat 3, which is more convenient to use. The condensed water sprays and cleans the dust-proof net 5 through the cleaning pipe 73 at the back of the dust-proof net 5, keeping the dust-proof net 5 clean and ensuring the dust-proof efficiency of the dust-proof net 5.

[0024] The back of the dust-proof net 5 refers to the side close to the dehumidification housing 1.

[0025] Embodiment 2, referring to Figure 1 - Figure 10 As shown, different from the above embodiment, the top of the water storage tank 2 is open, and a pressing assembly 8 is further arranged in the dehumidification housing 1. The pressing assembly 8 includes a diversion cover 81, a pressing cover 82, a pressing cylinder 83, a plurality of pressing blocks 84 and a plurality of pressing teeth 85. Condensed water can flow into the diversion cover 81. The pressing cover 82 is sleeved on the diversion cover 81. The pressing cylinder 83 is fixedly installed in the diversion cover 81. The pressing cover 82 is fixedly installed at the output end of the pressing cylinder 83. A plurality of pressing blocks 84 are fixedly installed at the bottom of the pressing cover 82 near both sides. A plurality of pressing teeth 85 are fixedly installed on both sides of the water storage tank 2.

[0026] The condensed water falls into the diversion cover 81 and enters the water storage tank 2 through the diversion cover 81 and the pressing cover 82.

[0027] The pressing cylinder 83 drives the pressing cover 82 to rise. The pressing cover 82 is separated from the water storage tank 2. The pressing cover 82 drives the pressing blocks 84 to rise. The pressing blocks 84 are separated from the pressing teeth 85. At this time, the water storage tank 2 can be removed to pour water, which is suitable for use when it is not necessary to clean the dust-proof net 5, with more choices and strong adaptability.

[0028] After moving the water storage tank 2 into the dehumidification housing 1, the pressing cylinder 83 drives the pressing cover 82 to descend. The pressing cover 82 presses in the water storage tank 2 to prevent the condensed water in the diversion cover 81 from leaking and can enter the water storage tank 2. At the same time, the pressing cover 82 drives the pressing blocks 84 to descend. The pressing blocks 84 move to one side of the pressing teeth 85, which can prevent the displacement of the water storage tank 2, make the water storage tank 2 more stable and not easy to shake, and ensure the seal between the water storage tank 2 and the pressing cover 82 without leaking condensed water.

[0029] The drainage assembly 4 further includes a push rod 42, a push plate 43, a return spring 44 and a support frame. The support frame is fixedly installed in the drain hole.

The drain valve plate 41 is fixedly installed at the top of the push rod 42. One end of the return spring 44 is fixedly installed on the push plate 43. The other end of the return spring 44 is fixedly installed on the support frame. The return spring 44 is sleeved on the push rod 42.

[0030] When the dehumidification housing 1 moves to the drainage seat 3, the drainage strip 6 squeezes the push plate 43 to rise. The push plate 43 drives the push rod 42 to rise and compresses the return spring 44 to store energy. The push rod 42 drives the drain valve plate 41 to rise, and the water flows out of the drain hole into the drainage seat 3.

[0031] After the dehumidification housing 1 is removed from the drain base 3, the return spring 44 presses and pushes the push plate 43 downward. The push plate 43 drives the drain valve plate 41 downward through the push rod 42, and the drain valve plate 41 closes the drain hole.

[0032] Embodiment 3, referring to Figure 1 - Figure 10 As shown, different from the above embodiment, the cleaning housing 71 is fixedly installed on the drain base 3. The cleaning assembly 7 further includes a threaded rod 74, a moving block 75, and a moving motor 76. The moving motor 76 is fixedly installed on the cleaning housing 71.

The threaded rod 74 is fixedly installed at the output end of the moving motor 76, and the other end of the threaded rod 74 is rotatably connected to the cleaning housing 71. The moving block 75 is fixedly installed on the cleaning plate 72, and the moving block 75 is sleeved on the threaded rod 74 and is threadedly connected to the threaded rod 74.

[0033] After the dehumidification housing 1 moves to the drain base 3, the dust-proof net 5 moves into the cleaning housing 71. The moving motor 76 drives the threaded rod 74 to rotate, the moving block 75 moves on the threaded rod 74, and the moving block 75 drives the cleaning plate 72 to move, so that the cleaning plate 72 moves to the back of the dust-proof net 5 to clean the dust-proof net 5.

[0034] There are two groups of the cleaning plate 72, the cleaning pipe 73, and the moving block 75. The threaded rod 74 is symmetrically threaded. The two cleaning plates 72 move from both sides of the dust-proof net 5 to the back of the dust-proof net 5.

[0035] Embodiment 4, referring to Figure 1 - Figure 10 As shown, different from the above embodiment, the cleaning assembly 7 further includes a driving water pump 77, a driving water pipe 78, a connecting hose 79, and a shunt pipe 70. The driving water pump 77 is fixedly installed in the cleaning tank. The driving water pipe 78 is fixedly installed at the output end of the driving water pump 77. One end of the connecting hose 79 is fixedly installed on the driving water pipe 78, and the other end of the connecting hose 79 is fixedly installed on the shunt pipe 70. A plurality of cleaning pipes 73 are fixedly installed on the shunt pipe 70. A plurality of spray heads are installed on the shunt pipe 70. The bottom of the cleaning tank is inclined towards the driving water pump 77.

[0036] The water in the water storage tank 2 flows into the cleaning tank. The driving water pump 77 passes the water into the driving water pipe 78. The driving water pipe 78 passes through the connecting hose 79 and the shunt pipe 70 into the cleaning pipe 73 and sprays water onto the dust-proof net 5 through the spray heads.

[0037] As another preferred embodiment, a second spray head is provided on the front of the dust-proof net 5 in the cleaning housing 71 to improve the cleaning effect on the dust-proof net 5.

[0038] As another preferred embodiment, a filter screen is detachably installed inside the drain base 3 corresponding to the inlet end of the driving water pump 77. The filter screen is used to filter large particle impurities washed off. After being used for a specified time, the filter screen is removed for cleaning.

[0039] Embodiment 5. Refer to Figure 1 - Figure 10 As shown in the figure, the difference from the above embodiment is that an air inlet is provided on the dehumidification housing 1. A push cylinder 9 is fixedly installed on the dehumidification housing 1 corresponding to the air inlet. The dust-proof net 5 is fixedly installed on the push cylinder 9. An avoidance notch is provided on the cleaning plate 72 corresponding to the push cylinder 9.

[0040] The push cylinder 9 pushes the dust-proof net 5 from the dehumidification housing 1 into the cleaning housing 71.

[0041] Embodiment 6. Refer to Figure 1 - Figure 10 As shown in the figure, the difference from the above embodiment is that several support wheels 10 are installed at the bottom of the dehumidification housing 1. Limit grooves are provided at the positions of the corresponding support wheels 10 on the drain base 3. The drain base 3 is gradually inclined.

[0042] The support wheels 10 make it easier and more convenient to move the dehumidification housing 1. After the dehumidification housing 1 moves onto the drain base 3, the limit grooves limit the support wheels 10 to improve stability.

[0043] Several moving wheels 11 are fixedly installed at the bottom of the water storage tank 2. A limit track is fixedly installed at the inner bottom of the dehumidification housing 1. The moving wheels 11 are arranged inside the limit track. Two water baffle plates are fixedly installed at the bottom of the water storage tank 2. The two water baffle plates are located on both sides of the drain hole. A groove is provided on the dehumidification housing 1 corresponding to the drain strip 6. An operation door is provided on the dehumidification housing 1 corresponding to the position of the water storage tank 2.

[0044] The moving wheels 11 make it easier to move the water storage tank 2. When the water storage tank 2 is located inside the dehumidification housing 1, the limit track limits the moving wheels 11 to improve stability. The operation door can take out the water storage tank 2 inside the dehumidification housing 1.

[0045] Embodiment 7. Refer to Figure 1 - Figure 10 As shown in the figure, the difference from the above embodiment is that a sliding rod 14 is fixedly installed inside the cleaning housing 71. A slider 15 is fixedly installed on the cleaning plate 72. The slider 15 is sleeved on the sliding rod 14 and is in sliding fit with the sliding rod 14. A drain pipe 20 is fixedly installed and communicated with the side surface near the bottom inside the cleaning housing 71. Handles are fixedly installed on both the water storage tank 2 and the dehumidification housing 1.

[0046] When the cleaning plate 72 moves, it drives the slider 15 to move on the sliding rod 14, making the movement of the cleaning plate 72 more stable.

[0047] As another preferred embodiment, the dehumidification housing 1 is installed on a laser-guided AGV, which is a prior art. When the water in the water storage tank 2 is full, the laser-guided AGV automatically navigates to the drainage seat 3 for drainage and cleaning of the dust filter 5.

[0048] Furthermore, the laser-guided AGV includes a vehicle body frame, a drive system, a navigation control module, a laser scanner, a reflector or an environmental feature recognition device, a sensor system, a power supply system, and a communication module. The vehicle body frame serves as a physical carrier and integrates the drive system internally. The drive system includes a servo motor, a reducer, and drive wheels, and is responsible for executing motion commands to achieve actions such as forward, backward, and turning. The navigation control module includes a main controller, an algorithm processor, and a positioning chip. It emits a laser beam through the laser scanner and receives the reflected signal. With the assistance of preset reflectors or natural environmental features, it uses the triangulation principle or the SLAM (Simultaneous Localization and Mapping) algorithm to calculate the coordinate position and heading angle of the AGV in real time. Combining the motion data of the inertial measurement unit (IMU) and the encoder for multi-sensor fusion positioning, the power supply system includes a lithium battery pack, and the communication module interacts with the upper-level scheduling system through a wireless network for task instructions and status information. Its working principle essentially is to continuously scan the environment through lidar to obtain high-precision distance data, generate an optimal driving path by combining the kinematic model and path planning algorithm, precisely control the movement of the wheel system by the drive system, and at the same time correct the trajectory deviation in real time through a closed-loop feedback mechanism, ultimately realizing driving the dehumidification housing 1 to move to the drainage seat 3.

[0049] A dehumidifier uses the above dehumidifier drainage structure. A compressor 16, a condenser 17, an evaporator 18, a capillary tube, and an induced draft fan 19 are arranged in the dehumidification housing 1. The condenser 17 and the evaporator 18 are both connected to the compressor 16. A capillary tube is connected between the condenser 17 and the evaporator 18. The induced draft fan 19 is arranged corresponding to the air inlet, and the dehumidification housing 1 is provided with an air outlet corresponding to the position of the evaporator 18.

[0050] The compressor 16 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gas. The high-temperature gas enters the condenser, liquefies after heat exchange with air through the heat sink, and turns into a high-pressure liquid state. → When the liquid refrigerant flows through the capillary tube, the pressure drops suddenly due to the sudden reduction in the tube diameter, forming a mixed state of low-temperature and low-pressure liquid and gas. → The mixed-state refrigerant enters the evaporator 18, absorbs the heat of the humid air flowing through the evaporator 18, and completely evaporates into a low-temperature and low-pressure gas. At the same time, the air loses heat and water is separated out. → The evaporated gaseous refrigerant is inhaled into the compressor 16 again to complete the cycle. This process repeats continuously, continuously condensing and separating the water vapor in the air to achieve the purpose of dehumidification. When the humid air is inhaled by the induced draft fan 19 and passes through the evaporator 18, since the surface temperature of the evaporator is lower than the dew point temperature of the air, the water vapor in the air condenses into liquid water and drips into the water storage tank 2. At the same time, the cooled and dried air then flows through the relatively high-temperature condenser 17, absorbs the heat released by the condenser 17, and the temperature rises but the humidity decreases. Finally, it is discharged in a relatively dry and warm state, thus completing the dehumidification cycle.

[0051] The condensed water of the evaporator 18 flows into the flow guide cover 81 through the pipeline to prevent the heating of the condenser 17.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
