Detailed Description
The present application provides an air conditioner including an indoor unit 10 and an outdoor unit (not shown). In some embodiments of the present application, the indoor unit 10 includes a cabinet, an evaporator 200, and a drip tray 300.
A heat exchange chamber is defined inside the cabinet, the evaporator 200 is disposed in the heat exchange chamber, and a photocatalyst layer 210 is disposed at a lower portion of the evaporator 200. The water pan 300 is disposed in the heat exchange chamber and below the evaporator 200, and is configured to receive defrosted water from the evaporator 200, and an ultraviolet sterilization device is disposed on an inner sidewall of the water pan 300 along a circumferential direction, and is configured to irradiate the photocatalyst layer 210 and the water pan 300.
Referring to fig. 1, fig. 1 is a schematic exploded view of an indoor unit of an air conditioner according to an embodiment of the present invention. In some embodiments of the present application, the housing may be formed of a plurality of panels, which may serve to protect and secure components disposed therein. The panels may generally include a front panel 110, a rear panel 120, a top panel 130 and a bottom panel 140, and the front panel 110, the rear panel 120, the top panel 130 and the bottom panel 140 form a heat exchange chamber. The front panel 110 may be provided with at least one air outlet 114 for discharging heat exchange air flow from the air outlet 114 into a room, and the rear panel 120 may be provided with at least one air inlet 122 for sucking indoor air from the air inlet 122 into the heat exchange chamber for heat exchange.
As described in the background section, the evaporator 200 serves as a heat exchange element of the air conditioner, when the air conditioner is used for cooling, the temperature of the surface of the evaporator 200 is low, and the evaporator cools and frosts water vapor in the air while exchanging heat with the air in the heat exchange chamber, and finally the frost is attached to the surface of the evaporator 200. When the air conditioner defrosts, the water receiving tray 300 under the evaporator 200 receives defrosted water. A small amount of water droplets remain in the water receiving tray 300 during each drainage, and harmful substances to the human body, such as viruses and bacteria in the air, easily contaminate the remaining defrosted water.
In this embodiment, a photocatalyst layer 210 for purifying air is provided at a lower portion of the evaporator 200, and an ultraviolet sterilizer for irradiating the photocatalyst layer 210 and the water tray 300 is provided on an inner wall of the water tray 300. The photocatalyst layer 210 can generate a substance having a strong oxidizing property (e.g., hydroxyl radical, oxygen, etc.) under irradiation of light, and can be used to decompose organic compounds, partially inorganic compounds, bacteria, viruses, etc. In daily life, the photocatalyst can effectively degrade toxic and harmful gases in the air, such as formaldehyde and the like, and efficiently purify the air; meanwhile, various bacteria can be effectively killed, and toxin released by the bacteria or fungi can be decomposed and harmlessly treated.
In this embodiment, the uv sterilization device disposed on the inner sidewall of the drip tray 300 can provide energy to the photocatalyst layer 210. When the ultraviolet sterilizer irradiates the photocatalyst layer 210, the photocatalyst layer 210 excites electrons to generate negative charges and positive charges. The negative charges combine with ozone in the air to form negatively charged ozone molecules; the water molecules adsorbed to the metal surface form positively charged water molecule compounds. The water molecular compound with positive charges deprives the ozone of ionic oxygen to generate oxygen anions and HO + positive ions or HO & HO + positive ions and HO to escape from the metal surface, thereby forming a purification factor of a magnetic energy high-order oxidation technology and being capable of purifying various pollutants such as bacteria, viruses and the like.
Further, the ultraviolet sterilization device can provide energy for the photocatalyst layer 210 and can irradiate the residual defrosting water in the water receiving tray 300 at the same time, so as to achieve the purpose of sterilization. In general, the defrosting water collected in the drain pan 300 is discharged at regular time, but a residual portion of the defrosting water is not completely discharged after each discharge, and the residual portion of the defrosting water is easily contaminated. Ultraviolet germicidal device sets up on the inside wall along defrosting tray 300's circumference, can provide the trigger energy for the photocatalyst layer 210 that sets up in the evaporimeter 200 bottom simultaneously after ultraviolet germicidal device opens, can shine again and remain the disinfection of disinfecting in defrosting water that defrosting tray 300, has realized simultaneously from two aspect simultaneously air-purifying, has improved purification efficiency, and the antibacterial rate is up to 99.99%.
