Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to a water-leakage-proof dehumidifier. Background Art

[0002] A dehumidifier primarily consists of a compressor, heat exchanger, fan, water tank, housing assembly, and control module. Its operating principle is: the fan draws humid air into the dehumidifier, where it passes through a low-temperature heat exchanger, condensing the air into small droplets. The treated, dry air is then discharged outside, a cycle that maintains a comfortable relative humidity in the room. Inside the dehumidifier, the heat exchanger, drain pan, and water tank are arranged in order from top to bottom. Condensate generated by the humid air passing through the heat exchanger flows along the heat exchanger fins into the drain pan, where it then drains into the water tank through a drain pipe. When the water in the water tank accumulates and reaches the full alarm level, the dehumidifier stops operating and the user must empty the water from the tank. A common solution is to simply remove the water tank from below the drain pan and discard the condensed water. However, during this process, any condensed water remaining on the heat exchanger and drain pan can continue to drip, flowing down the drain pipe into the dehumidifier or onto the floor, impacting the user experience.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings.

[0025] Refer to Figures 1 to 7, A leak-proof dehumidifier, comprising a housing assembly 1, a compressor 2, a heat exchanger 3, and a fan assembly 4 disposed within the housing assembly 1, and a water tank 5 disposed at the bottom of the housing assembly 1. A water receiving tray 6 is provided below the heat exchanger 3. The water receiving tray 6 includes a diversion groove 61 and a drain pipe 62 that communicates with the diversion groove 61 and can drain the water in the diversion groove 61 into the water tank 5. The diversion groove 61 is located at the lowest point of the water receiving tray 6, so that the water on the water receiving tray 6 can flow into the diversion groove 61 and then be discharged by the drain pipe 62. There is also a water full switch 7 provided in the water tank 5 to remind the user that the water in the water tank 5 is full and needs to be taken out and emptied. In order to avoid, after the water tank 5 is filled with water, when the water tank 5 is taken out to pour water, since there is no water tank 5 below the water receiving tray 6, the condensed water remaining on the heat exchanger 3 and the water receiving tray 6 may flow from the drain pipe 62 of the water receiving tray 6 into the interior of the dehumidifier or onto the floor, thereby affecting the user experience. Therefore, a delay alarm module 8 that is electrically connected to the water full switch 7 and can perform a delayed alarm after the water full switch 7 is triggered is provided within the housing assembly 1. In this way, after the water tank 5 is full, the delay alarm module 8 will control the compressor 2 to stop working and then perform a delayed alarm, so that the condensed water remaining on the heat exchanger 3 and the water receiving tray 6 is discharged into the water tank 5 through the drain pipe 62. When the water tank 5 is taken out, the condensed water will no longer flow out from the drain pipe 62 and onto the outside of the dehumidifier, and at the same time, the structure is simple. The delay time can be but does not include 5 minutes, so that the condensed water remaining on the heat exchanger 3 and the water receiving tray 6 is discharged into the water tank 5.

[0026] Reference Figure 1 and Figure 2 , In this solution, the housing assembly 1 includes a base 11, an outer housing 12 and an inner housing 13 disposed on the base 11, an upper cover 14 covering the outer housing 12, and a volute 15 disposed within the outer housing 12. The base 11 is detachably connected to the outer housing 12 or the inner housing 13 by means of snap connection or threaded connection, and the same applies to the connection between the outer housing 12 and the inner housing 13 or the upper cover 14, which facilitates the disassembly, cleaning, replacement, and repair of the housing assembly 1. The fan assembly 4 is disposed within the air duct cavity of the volute 15, and an air inlet is provided on the outer housing 12, and an air outlet is provided on the upper cover 14 for dehumidification. The water tank 5 is inserted and clamped onto the inner housing 13, and the water tank 5 is in contact with the outer housing 12, making it look simple and beautiful.

[0027] Reference Figure 3 and Figure 6, in this solution, on both sides of the water tank 5, there are outwardly protruding insertion parts 51, and on the outer side of the insertion parts 51, there are limit clamping protrusions 511. At the same time, on both sides of the inner housing 13, there are inwardly recessed docking parts 131, and on the docking parts 131, there are elastic buckles 1311 that cooperate with the limit clamping protrusions 511. In this way, the overall length of the water tank will not be too long, so that the user can take out or put back the water tank 5. At the same time, the water tank 5 can be stably fixed on the inner housing 13. Specifically, the insertion part 51 includes a first insertion part 512 on the right side and a second insertion part 513 on the left side. The docking part 131 includes a first docking part 1312 that cooperates with the first insertion part 512 and a second docking part 1313 that cooperates with the second insertion part 513.

[0028] Reference Figure 4 and Figure 5 , in this solution, the position of the diversion groove 61 corresponds to the first docking part 1312 and is located below the fins on one side of the heat exchanger 3, so that the condensed water can directly drip into the diversion groove 61. At the same time, the diversion groove 61 has a diversion slope, so that the condensed water dripping into the diversion groove 61 is diverted by the diversion slope and discharged through the drain pipe 62. Preferably, the water receiving tray 6 and the inner housing 13 are of an integral structure, and the drain pipe 62 is arranged inside the first docking part 1312, so as to optimize the structure, facilitate production and reduce the installation steps; in addition, the bottom surface of the water receiving tray 6 slopes downward gradually from left to right, so that the condensed water dripping onto the water receiving tray 6 can flow into the diversion groove 61.

[0029] Reference Figure 4 , in this solution, below the outlet of the drain pipe 62, there is a drain trough 621, and the width of the drain trough 621 gradually increases from inside to outside, so as to limit the area where the condensed water drips from the drain pipe 62 into the water tank 5, which is beneficial to dripping the condensed water into the water tank 5 and preventing it from flowing outside the water tank 5.

[0030] Reference Figure 1 and Figure 7 , in this solution, inside the second insertion part 513, there is a limit cavity 5131 that communicates with the inside of the water tank 5. The water full switch 7 includes a float switch 71 arranged in the limit cavity 5131. At the same time, the delay alarm module 8 includes a control board 81 arranged on the housing assembly 1 and electrically connected to the float switch 71, as well as a buzzer 82 and an indicator light 83 that are electrically connected to the control board 81. In this way, after the float switch 71 is triggered, the information will be fed back to the control board 81, and the control board 81 will control the compressor 2 to stop working, then execute the delay command, and after the delay ends, it will control the buzzer 82 and the indicator light 83 to give an alarm.

[0031] Reference Figure 6, in this solution, a cover plate 52 is provided above the water tank 5, and an opening 521 is provided on the cover plate 52 and below the outlet of the drain pipe 62, so that the condensed water drips into the water tank 5 from the opening 521. At the same time, the cover plate 52 is used to prevent the water dripping into the water tank 5 from splashing out and the water in it from scattering when the water tank 5 is taken out for transportation. There is a gap between the rear side of the cover plate 51 and the water tank 5, which facilitates the rapid pouring out of the water in the water tank 5.

[0032] Reference Figure 6 and Figure 7 , in this solution, a groove 121 is provided at the bottom of the outer housing 12 and at the place where it fits with the water tank 5, which facilitates the user to take out the water tank 5 from the inner housing 13; at the same time, a handle 53 is hinged above the cover plate 51 on the water tank 5 to facilitate the lifting of the water tank 5. And there are rib plates in the water tank 5, and hinge holes are provided on the rib plates for hinging with the handle 53. In this way, when the water tank 5 is lifted by the handle 53, the internal force of the water tank 5 is balanced and it is not easy to be damaged.
