Description

A dehumidifier with humidity control function Technical Field

[0001] This utility model relates to the field of dehumidifier technology, specifically a dehumidifier with humidity regulation function. Background Technology

[0002] A dehumidifier is an appliance that extracts moisture from the air and re-exposes dry air into the room using a compressor and condensation principle. It is widely used in homes, offices, basements, industrial sites, etc., to reduce indoor humidity, prevent the growth of mold and bacteria, and improve air quality.

[0003] In existing dehumidifiers, air is drawn into the unit and filtered through a screen to reduce impurities. However, with prolonged use, these filters easily become clogged, affecting airflow and dehumidification efficiency. Regular cleaning of the filters is necessary, but currently, it's mostly done manually, which is cumbersome and inconvenient for using a vacuum nozzle to remove dust and impurities using negative pressure. Therefore, we propose a dehumidifier with humidity control functionality. Summary of the Invention

[0004] The purpose of this invention is to provide a dehumidifier with humidity regulation function, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dehumidifier with humidity regulation function, comprising a dehumidifier body, wherein a mesh cover is rotatably installed at the air inlet of the dehumidifier body, and an air outlet is provided on the lower side of one side wall of the dehumidifier body and a dustproof mesh plate is fixed inside the air outlet.

[0006] A negative pressure suction nozzle is provided on the lower side of the outer wall of the mesh cover. The negative pressure suction nozzle is fixedly connected to the outer wall of the dehumidifier body. A filter box is fixedly installed on the lower side of the outer wall of the dehumidifier body. A filter screen is fixedly installed in the inner cavity of the filter box. A negative pressure fan is fixedly connected to the bottom of the filter box. The top of the filter box is fixedly connected to the negative pressure suction nozzle through a fixed pipe.

[0007] By adopting the above technical solution, air enters the dehumidifier body through the mesh cover for dehumidification. The dehumidified air is then discharged through the air outlet. When the mesh cover has accumulated a lot of dust and impurities during long-term use, a negative pressure fan creates negative pressure in the filter box, which in turn allows the negative pressure nozzle to remove the dust and impurities from the mesh cover and then filter and collect them in the filter box.

[0008] In a preferred embodiment of this utility model, a fixed shell is provided on the outer side of the mesh cover, and a rotating shaft is rotatably installed in the inner cavity of the fixed shell. One end of the rotating shaft movably passes through the fixed shell and is fixedly connected to the middle of the outer end face of the mesh cover. Multiple evenly distributed blades are fixedly installed on the outer wall of the rotating shaft. The output end of the negative pressure fan is fixedly connected to the bottom side of the fixed shell through a duct.

[0009] By adopting the above technical solution, the air force from the air outlet at the other end of the negative pressure fan is directed to the inner cavity of the fixed shell, so that the air blows onto the blades, thereby driving the rotating shaft to rotate, which in turn drives the mesh cover to rotate. This allows the negative pressure suction nozzle to remove dust and impurities from different positions on the mesh cover, which helps to improve the comprehensiveness of cleaning.

[0010] In a preferred embodiment of this utility model, an air vent is provided on one side of the top of the fixed shell, and a filter screen is installed inside the air vent.

[0011] In a preferred embodiment of this utility model, connecting rods are fixed to both sides of the fixed shell, and the outer ends of the connecting rods are fixedly connected to the dehumidifier body.

[0012] In a preferred embodiment of this utility model, a humidity sensor is fixedly installed on the top of the dehumidifier body, and a controller is fixedly installed on one side wall of the dehumidifier body.

[0013] In a preferred embodiment of this utility model, a carrier plate is fixed to the bottom of the dehumidifier body, and casters are fixed to the four corners of the bottom of the carrier plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The present application provides a dehumidifier with humidity regulation function. By operating a negative pressure fan, a negative pressure is created in the filter box, which allows the negative pressure nozzle to remove dust and impurities from the surface of the mesh cover, thereby achieving cleaning. This replaces the previous manual operation, which improves the convenience of cleaning operations. At the same time, negative pressure dust removal helps to avoid dust generation.

[0016] The airflow from the outlet at the other end of the negative pressure fan is directed into the inner cavity of the fixed shell, causing the air to blow onto the blades, which in turn drives the rotating shaft to rotate, thereby causing the screen to rotate. This allows the negative pressure nozzle to remove dust and impurities from different parts of the screen, improving the overall cleaning effectiveness.

[0017] The humidity sensor detects humidity data and sends it back to the controller, which then starts and stops the dehumidifier when the specified humidity level is reached, thereby regulating the humidity and improving its adaptability. Attached Figure Description

[0025] Please refer to Figures 1-3. This utility model provides a technical solution: a dehumidifier with humidity regulation function, including a dehumidifier body 1, a mesh cover 12 rotatably installed at the air inlet of the dehumidifier body 1, and an air outlet is opened on the lower side of one side wall of the dehumidifier body 1, and a dustproof mesh plate 13 is fixed inside the air outlet.

[0026] A negative pressure suction nozzle 21 is provided on the lower side of the outer wall of the mesh cover 12. The negative pressure suction nozzle 21 is fixedly connected to the outer wall of the dehumidifier body 1. A filter box 2 is fixedly installed on the lower side of the outer wall of the dehumidifier body 1. A filter screen is fixedly installed in the inner cavity of the filter box 2. A negative pressure fan 22 is fixedly connected to the bottom of the filter box 2. The top of the filter box 2 is fixedly connected to the negative pressure suction nozzle 21 through a fixed pipe.

[0027] It should be noted that the working principle of the dehumidifier body 1 is as follows: the fan draws humid air into the dehumidifier, removes dust and other impurities through the filter, and the compressor drives the refrigerant to circulate in the evaporator, condenser, and capillary tube. The surface temperature of the evaporator drops below the dew point. When the humid air passes through the low-temperature evaporator, water molecules condense into liquid water droplets upon contact with the condenser, which drip into the water tank or are discharged through the drain pipe. The dehumidified dry air is heated by the condenser and then discharged into the room by the fan, completing the cycle.

[0028] It should be understood that in actual use, air enters the dehumidifier body 1 through the mesh cover 12 for dehumidification, and the dehumidified air is discharged through the air outlet. When there is a lot of dust and impurities on the surface of the mesh cover 12 after long-term use, the negative pressure fan 22 creates a negative pressure in the filter box 2, which allows the negative pressure nozzle 21 to create a negative pressure to suck up the dust and impurities on the mesh cover 12 and then introduce them into the filter box 2 for filtration and collection.

[0029] Furthermore, a carrier plate 11 is fixed to the bottom of the dehumidifier body 1, and a caster wheel 14 is fixed to each of the four corners of the bottom of the carrier plate 11. The caster wheel 14 makes it convenient to move and reposition the entire device.

[0030] As shown in Figures 1 and 2, a fixed shell 24 is provided on the outer side of the mesh cover 12. A rotating shaft 26 is rotatably installed in the inner cavity of the fixed shell 24. One end of the rotating shaft 26 movably passes through the fixed shell 24 and is fixedly connected to the middle of the outer end face of the mesh cover 12. Multiple evenly distributed blades 27 are fixedly installed on the outer wall of the rotating shaft 26. The output end of the negative pressure fan 22 is fixedly connected to the bottom side of the fixed shell 24 through the duct 23.

[0031] It should be understood that the airflow from the outlet of the negative pressure fan 22 is directed into the inner cavity of the fixed housing 24, thereby blowing the air onto the blades 27, which in turn drives the rotating shaft 26 to rotate, thereby driving the mesh cover 12 to rotate. This allows the negative pressure suction nozzle 21 to remove dust and impurities from different positions on the mesh cover 12, which helps to improve the comprehensiveness of cleaning.

[0032] Furthermore, an air vent 25 is provided on one side of the top of the fixed shell 24, and a filter screen is installed inside the air vent 25, so that the air vent 25 can exhaust the gas inside the fixed shell 24.

[0033] Furthermore, connecting rods are fixed to both sides of the fixed shell 24, and the outer ends of the connecting rods are fixedly connected to the dehumidifier body 1. The setting of the connecting rods makes the fixed shell 24 highly stable.

[0034] As shown in Figures 1 and 2, a humidity sensor 15 is fixedly installed on the top of the dehumidifier body 1, and a controller 16 is fixedly installed on one side wall of the dehumidifier body 1.

[0035] It should be understood that the signal output terminal of the humidity sensor 15 is connected to the signal input terminal of the controller 16, and the signal output terminal of the controller 16 is connected to the signal input terminal of the dehumidifier body 1. Thus, the humidity sensor 15 can detect the humidity of the environment, and the controller 16 can set the humidity threshold in advance before dehumidification. When the humidity reaches the threshold during dehumidification, the controller 16 can stop the dehumidifier body 1 from working, thereby stopping dehumidification. When the humidity exceeds the humidity threshold again, the dehumidifier body 1 will be restarted to dehumidify, thereby achieving automatic humidity adjustment and improving usability.
