[0033] From the above description, it can be seen that the beneficial effects of the utility model are:

[0034] The present invention provides a partition in the inner cavity of the shell, which divides the inner cavity of the shell into a first cavity and a second cavity. A regeneration fan bracket, a regeneration fan, an air inlet duct, a fan connector and a heat preservation box are provided in the first cavity. The regeneration fan bracket is installed on the bottom surface of the first cavity, and the regeneration fan is installed on the regeneration fan bracket. One end of the air inlet duct is installed on a side surface of the first cavity opposite to the partition. The fan connector is located between the air inlet duct and the regeneration fan. The fan connector is connected and communicated with the air inlet duct and the regeneration fan respectively. One end of the heat preservation box is installed on the partition, and the other end of the heat preservation box is connected and communicated with the fan connector. A main fan bracket, a main fan, a rotor bracket, a rotor and a wet air duct are provided in the second cavity. The main fan bracket is installed On the bottom surface of the second cavity, the main fan and the impeller bracket are both installed on the main fan bracket, one end of the wet air duct is installed on the side surface of the second cavity opposite to the partition, the other end of the wet air duct is installed on the impeller bracket, the other end of the wet air duct is connected to and communicated with one end of the impeller, the other end of the impeller is installed on the partition and the other end of the impeller is communicated with the other end of the insulation box body. Such a structure makes each component independent. When the main fan needs to be maintained, it is only necessary to remove the screws locking the main fan bracket for maintenance. When the insulation box body needs maintenance, it is only necessary to remove the cover of the insulation box body for maintenance. When the regeneration fan needs maintenance, it is only necessary to remove the screws locking the fan connector for maintenance. Similarly, there is no need for a sequence when installing.

[0035] Furthermore, the thermal insulation box body includes an outer box body and an inner box body, the inner box body is arranged inside the outer box body, and the space between the inner box body and the outer box body is filled with thermal insulation cotton, and a plurality of heating modules are arranged at equal intervals inside the inner box body, and the plurality of heating modules are connected by a heating connector.

[0036] From the above description, it can be seen that the thermal insulation box adopts an inner and outer double-layer structure and is filled with thermal insulation cotton in the middle, which has a good thermal insulation effect. The thermal insulation cotton is not wrapped outside the box, so the appearance remains good.

[0037] Furthermore, the heating module is a PTC heating sheet.

[0038] From the above description, we can see that the PTC heating sheet has rapid heating, no glue bonding, is healthy and environmentally friendly, has uniform temperature distribution, and has its own thermostat. It will automatically cut off the power when the temperature is too high, which is safe and reliable.

[0039] Furthermore, the heating connecting piece includes a connecting plate and a plurality of mounting plates, wherein the plurality of mounting plates are vertically mounted at equal intervals on a side surface of the connecting plate, and one heating module is mounted on one mounting plate.

[0040] As can be seen from the above description, the heating module is assembled into a whole through the heating connector, which is convenient and simple to install or maintain. There is no need to assemble them one by one in the insulation box, which further improves the convenience of installation.

[0041] Furthermore, the wet air duct and the rotor are connected via a sealing assembly.

[0042] Furthermore, the sealing assembly includes a sealing strip and a sealing frame, the sealing frame is installed corresponding to the air outlet of the wet air duct, the sealing strip is arranged along the edge of the sealing frame, and the sealing strip is connected to the rotating wheel.

[0043] From the above description, it can be seen that a sealing strip is installed at the place where the wet air duct contacts the rotor to prevent the wet air from overflowing.

[0044] Furthermore, a friction plate is locked onto the belt on the outer wall of the rotating wheel.

[0045] From the above description, it can be seen that the wheel is driven by a motor to rotate the belt installed on the outer wall of the wheel, thereby driving the wheel to rotate. If the wheel stops rotating when the dehumidifier is working, the dehumidification effect will not be achieved. It may also cause the local temperature of the wheel to rise and cause the wheel to carbonize and break. Therefore, a friction plate is locked on the belt on the outer wall of the wheel to effectively prevent the belt from slipping during operation.

[0046] Furthermore, the top of the shell has a first opening, and a top cover is detachably connected to the first opening. A side surface of the shell has a second opening, and a back cover is detachably connected to the second opening.

[0047] It can be seen from the above description that the shell, the top cover and the back cover all adopt a detachable structure, which can facilitate assembly and maintenance.

[0053] During installation, screws are fixed to the main fan bracket 41, and the main fan 42 is fixed to the main fan bracket 41 with screws, and the rotor bracket 43 is fixed at the same time, and then one end of the wet air duct 45 is fixed to the rivet of the shell 1 with a nut, and the other end of the wet air duct 45 is fixed to the rotor bracket 43 with screws.

[0054] Please refer to Figure 1 The thermal insulation box 35 includes an outer box 351 and an inner box 352. The inner box 352 is arranged inside the outer box 351, and the space between the inner box 352 and the outer box 351 is filled with thermal insulation cotton. A plurality of heating modules 3521 are arranged at equal intervals inside the inner box 352, and the plurality of heating modules 3521 are connected by a heating connector.

[0055] The heating module 3521 is a PTC heating sheet.

[0056] Please refer to Figure 4 The heating connecting piece includes a connecting plate 3522 and a plurality of mounting plates 3523 , wherein the plurality of mounting plates 3523 are vertically mounted at equal intervals on a side surface of the connecting plate 3522 , and one heating module 3521 is correspondingly mounted on one mounting plate 3523 .

The heating module 3521 is a heating module assembled into an integral structure by screwing multiple PTC heating plates using an L-shaped connector to facilitate operation and subsequent maintenance.

[0059] Please refer to Figure 1 and Figure 3 The sealing assembly 46 includes a sealing strip 461 and a sealing frame 462 . The sealing frame 462 is installed corresponding to the air outlet of the wet air duct 45 . The sealing strip 461 is arranged along the edge of the sealing frame 462 .

Therefore, in this solution, the rivets are first pressed onto the bottom plate, and then the bottom plate is welded to the shell 1. This can effectively improve the rivet marks, and the process is simple and the appearance is good.
