Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a heat exchange device capable of humidifying air. Background Technology

[0002] As people's demands for indoor air quality increase, air handling equipment that combines temperature regulation and humidity control is gradually becoming the mainstream in the market. Traditional air conditioning equipment usually separates heat exchange and humidification functions, and there are many technical problems in its use, specifically as follows: During the heat exchange process, water vapor in the air condenses upon contact with the cold air, producing a large amount of condensate. Traditional equipment usually discharges the condensate directly or through a simple drain pipe, failing to effectively recycle it. This not only wastes water resources but also increases the drainage and maintenance costs of the equipment. In existing equipment, the filters are usually designed as fixed units, which are easily clogged by dust and impurities after long-term use, leading to a decrease in condensate collection efficiency. The humidification function relies on water in the water tank for atomization, but after long-term use, bacteria, algae, or scale can easily grow on the inner wall of the water tank, affecting the humidification effect and air quality. Traditional water tank cleaning methods require disassembling parts and manual cleaning, which is complicated. To address the above problems, existing technologies usually use condensate recovery devices, removable filters, or ultraviolet germicidal lamps, but these solutions often only solve a single problem and are complicated to use. Therefore, it is necessary to design a heat exchange treatment device that can integrate humidification, condensate recovery, and self-maintenance functions. Summary of the Invention

[0037] The sealing unit includes a sealing motor 411, a sealing gear 412, a sealing gear ring 413, a sealing plate 420, a sealing plate 421, and a sealing cover 423. The sealing motor 411 is fixedly installed on the outer surface of the water tank 414. The output shaft of the sealing motor 411 and the sealing gear 412 are fixedly installed. The sealing gear 412 and the sealing gear ring 413 are meshed together. The sealing gear ring 413 and the sealing plate 421 are fixedly installed.

The sealing cover 423 is installed on the sealing plate 421. A round tube is provided at the bottom of the sealing cover 423.

[0038] The working principle of this invention is as follows: the heat exchanger 203 and the motor 201 are started. The temperature is regulated by the heat exchanger 203 and the column fan 204 is driven to rotate by the motor 201 to blow out the air inside the baffle 202.

[0039] Water droplets are generated when the heat exchanger 203 is working. The water droplets are collected by the water receiving tray 301. The water droplets inside the water receiving tray 301 enter the filter 303 through the upper connector 302 at the bottom of the water receiving tray 301. The water is filtered by the filter 303, and then enters the hose through the lower connector 304. Finally, the water enters the water tank 414 through the hose. The water is sterilized by the disinfection lamp 418, and then the water is atomized by the atomizing plate 417. The water mist is discharged through the humidification port 403 by the fan to humidify the air.

[0040] When filter 303 becomes clogged, the water level inside water tray 301 rises, and water enters water cylinder 308 from overflow pipe 307. As the amount of water in water cylinder 308 increases, it causes water cylinder 308 and connecting frame 309 to descend, compressing spring 311. Connecting frame 309 causes limit rod 322 and lever 320 to descend. Lever 320 causes ratchet 315 to rotate, ratchet 315 causes bevel gear 319 to rotate, bevel gear 319 causes bevel gear 306 and lower connector 304 to rotate, and lower connector 304 causes filter 303 and upper connector 302 to rotate, thus moving the unclogged filter 303 to below the bottom round hole of water tray 301.

[0041] When the solenoid valve 312 is opened, the water inside the water receiving cylinder 308 flows into the water receiving box 323 through the central pipe 310 and the drain pipe 314. The spring 1 311 drives the water receiving cylinder 308 to reset. The water receiving cylinder 308 drives the connecting frame 309 and the lever 320 to rise. Under the action of the pawl 316 and the spring plate 317, the ratchet 315 can only rotate in one direction. Therefore, when the lever 320 rises, the ratchet 315 will not rotate. Under the action of the ratchet 315, the lever 320 compresses the spring 2 321, so that the ratchet 315 will not hinder the rise of the lever 320 and reset the lever 320.

[0042] When it is necessary to clean the inside of the water tank 414, the electric actuator 409 is activated. The extension rod of the electric actuator 409 drives the push plate 410 to rise. The push plate 410 pushes the side of the water tank 414 near the sealing gear ring 413 to rise, preventing water from flowing out of the water tank 414. The sealing motor 411 is activated, which drives the sealing gear 412 to rotate. The sealing gear 412 drives the sealing gear ring 413 to rotate. The sealing gear ring 413 drives the second sealing plate 421 to rotate, so that the rectangular hole on the second sealing plate 421 coincides with the rectangular hole on the first sealing plate 420. The reciprocating motor 408 is activated, which drives the lead screw 415 to rotate. The lead screw 415 drives the cleaning brush 422 to slide on the fixed rod 416, passing the cleaning brush 422 through the sealing plate. The second sealing plate 421 and the first sealing plate 420 enter the inner wall of the water tank 414; the rotary motor 404 is started, the rotary motor 404 drives the rotary gear 405 to rotate, the rotary gear 405 drives the rotary gear ring 406 to rotate, the rotary gear ring 406 drives the rotary disk 407 to rotate, thereby driving the cleaning brush 422 to rotate. The cleaning brush 422 cleans the inner wall of the water tank 414 by moving laterally on the fixed rod 416 and by rotating the cleaning brush 422; after cleaning, the electric push rod 409 drives the push plate 410 to descend, so that the side of the water tank 414 close to the sealing gear ring 413 descends. The water inside the water tank 414 flows into the sealing cover 423 through the first sealing plate 420 and the second sealing plate 421, and is discharged into the water receiving box 323 through the round pipe at the bottom of the sealing cover 423.
