A side air inlet grille 10 is installed on one surface of the lower end of the air-conditioning steel bracket 1, and a swing vane motor 11 is installed above the side air inlet grille 10. A windshield 12 is installed on the rotating end of the leaf motor 11, a connecting ring 13 is installed on one side of the windshield 12, a connecting nail 14 is installed on one side of the swing blade motor 11, and a spring 15 is connected to the connecting nail 14, and the lower end of the spring 15 is connected to the The ring 13 is fixedly connected, and the main problems it solves are: the first temperature and humidity probe 2 detects the temperature and humidity in the room, installs the wet film 5 on the lower end of the air-conditioning steel bracket 1, and circulates the water on the wet film 5 through the water pump 7. When in use, the air is humidified through the wet film 5, so as to humidify the interior of the room and maintain a certain temperature and humidity,

The application is also provided with an air outlet mechanism, a heat exchange mechanism, and a control mechanism. When in use, an instruction is issued by the remote controller 39 in the control mechanism, which is automatically controlled by the controller 38 to start the centrifugal fan 20 in the air outlet mechanism. The air in the room is drawn into the air conditioner by the lower air inlet grille. After a series of humidification or heat exchange, the air is discharged through the deflector 33. The indoor heat exchanger 22 in the heat mechanism makes it generate heat or cold air. When the air passes through, the temperature of the air is changed, so as to achieve the purpose of cooling the room. The specific working mode is as follows:

The first mode, summer cooling: turn on the power supply, issue commands through the remote controller 39, and automatically control the controller 38 to start the compressor in the outdoor unit to discharge the high-temperature and high-pressure refrigerant vapor to the four-way reversing valve, and the four-way The reversing valve sends the steam to the outdoor condenser, and the condensed normal temperature and high pressure refrigerant enters the indoor unit through the inlet pipe joint 29. At this time, the one-way valve 37 is used for conduction in winter, and the refrigerant does not pass through the capillary tube 35 for winter and the dryer for winter. The filter 34 directly passes through the one-way valve 37 for winter use, and then flows to the sight glass 32. At this time, the one-way valve 36 for summer use is not conducting, and the refrigerant is first dried by the drying filter 31 used in summer, and then passed through The capillary 30 is throttled, the damp steam after throttling enters the indoor heat exchanger 22 through the liquid separation head 27 to evaporate and absorb heat, and then comes out from the indoor heat exchanger 22 through the return pipe 23 and returns to the four-way reversing valve of the outdoor unit, and then After returning to the compressor to complete a refrigeration cycle, the water discharged from the indoor heat exchanger 22 falls on the second water receiving tray 25 and is discharged through the water outlet pipe 26. At this time, the indoor heat exchanger 22 is cooled, and the centrifugal fan 20 is started to blow The outside air is drawn into the air-conditioning steel bracket 1 through the front air inlet grille 41. After the air is heated by the indoor heat exchanger 22, the cold air is discharged from the air outlet grille 42 and the guide plate 33 to cool the room.

The second mode, heating in winter: start the outdoor compressor to discharge the high-temperature and high-pressure refrigerant vapor to the four-way reversing valve, and the four-way reversing valve sends the refrigerant vapor to the indoor heat exchanger 22 through the return pipe 23, and the refrigerant After the steam condenses and releases heat indoors, it joins through the liquid separator 27 and enters the intake pipe 28. At this time, the one-way valve 36 is used for conduction in summer, and the refrigerant does not pass through the capillary tube 30 for summer and the filter drier 31 for summer, and directly from the one-way valve in summer. The direction valve 36 passes through, and then flows to the sight glass 32. At this time, the one-way valve 37 for winter is not conducting. The refrigerant is first dried by the drying filter 34 for winter, and then throttled into wet steam through the capillary 35 for winter. Through the inlet pipe joint 29, it returns to the outdoor heat exchanger of the outdoor unit to evaporate and absorb heat, and then returns to the four-way reversing valve of the outdoor unit, and returns to the compressor through the four-way reversing valve to complete a heating cycle. At this time, the indoor heat exchanger 22 Heating, start the centrifugal fan 20, and draw the outside air into the air-conditioning steel bracket 1 through the front air inlet grille 41. After the air is heated by the indoor heat exchanger 22, the hot air is drawn from the air outlet grille 42 and the guide plate. 33 is exhausted to heat the room.

The third mode, humidification: the indoor temperature and humidity are detected by the first temperature and humidity probe 2 and the second temperature and humidity probe 21, and the signal is sent to the controller 38 through the signal transmission line 40. When the humidity in the air is sufficient, humidification Each component in the mechanism is not energized, only the windshield 12 rotates clockwise under the pulling force of the spring 15 to open the side air inlet grille 10 . Because the wet film 5 is installed behind the front air inlet grille 41, the wind resistance is relatively large, and the air enters from the side without passing through the wet film 5, and the air is not humidified; when the humidity in the air is insufficient, the water pump 7 is powered on to start pumping water through the stainless steel water pipe 8 is sent to the spray head 9, the spray head 9 sprays the water on the wet film 5 evenly, part of the unevaporated water flows into the water tank 3 through the first water receiving tray 4, and at the same time, the swing motor 11 is energized to overcome the tension of the spring 15. The wind deflector 12 rotates counterclockwise, thereby blocking the side air inlet grille 10, so that the air can only enter from the front air inlet grille 41, thereby humidifying the air through the wet film 5 abutting against the front air inlet grille 41, during the process. If the water level in the water tank 3 is lower than the set water level, the liquid level regulating valve 17 is opened, and the tap water flows into the water in the supplementary water tank 3, thereby adjusting the humidity in the air. During this process, the device can automatically detect the humidity in the air, And it starts to humidify the air by itself to ensure the comfortable humidity in the air and avoid excessive indoor humidity, and this device is installed in the remaining space of the return air outlet at the lower part of the cabinet air conditioner to reduce the space occupied by the humidifier.

The humidification mode can be activated at the same time during the cooling or heating process, or it can be activated independently, that is, the air conditioner can also be used as a separate humidifier, saving indoor humidification devices.

The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention, and some changes that those skilled in the art may make to some parts of them all reflect the principles of the present invention and belong to the protection scope of the present invention. within.
