Problems solved by technology

[0002] The power of the current electric heating belt is not enough, and the ice on the drain outlet of the outdoor unit cannot be completely melted at minus 15 degrees, resulting in snow and ice accumulation on the outdoor unit when the split indoor air conditioner is working in a severe cold area. Occurrence, it is easy to cause abnormal noise due to the collision and friction between the fan blade and the ice when the external machine is running, which will seriously cause mechanical failure and other shutdown phenomena

Embodiment Construction

[0051] see in conjunction Figure 1 to Figure 11 As shown, according to the first embodiment of the present application, the outdoor unit includes a chassis 1, a microwave heating device 3 and / or an infrared heating device is provided corresponding to the chassis 1, and the heating part of the microwave heating device 3 and / or the infrared heating device faces the chassis 1, and can heat the chassis 1.

[0052] The outdoor unit uses a microwave heating device 3 and / or an infrared heating device to heat the chassis 1, which can solve the problem of insufficient electric heating power in the prior art. When the outdoor ambient temperature is too low, the chassis 1 cannot be effectively deiced, resulting When the machine is running, the problem of collision and friction between the fan blades and the ice cubes, using microwave or infrared to penetrate the ice layer to heat the chassis, effectively avoids the isolation effect of the ice layer on heat conduction, so that the heat c...

Abstract

The invention provides an outdoor unit and a control method thereof, and an air conditioner. The outdoor unit comprises a controller, a base tray (1) and an outdoor heat exchanger (2), a microwave heating device (3) and / or an infrared heating device are / is arranged in a manner of corresponding to the base tray (1), a heating part of the microwave heating cavity (3) and / or a heating part of the infrared heating device face / faces the base tray (1), and can heat the base tray (1), a temperature sensor is arranged on the base tray (1), and is electrically connected to the controller, and the controller controls the microwave heating device (3) and / or the infrared heating device according to the temperature, detected by the temperature sensor, of the base tray (1). According to the outdoor unit, the deicing effect of the outdoor unit can be improved, and the friction between fan blades and an ice block can be effectively avoided.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to an outdoor unit, a control method thereof, and an air conditioner. Background technique [0002] The power of the current electric heating belt is not enough, and the ice on the drain outlet of the outdoor unit cannot be completely melted at minus 15 degrees, resulting in snow and ice accumulation on the outdoor unit when the split indoor air conditioner is working in a severe cold area. Occurs, it is easy to cause abnormal noise due to the collision and friction between the fan blade and the ice when the external machine is running, which will seriously cause mechanical failure and other shutdowns. Contents of the invention [0003] Therefore, the technical problem to be solved in this application is to provide an outdoor unit and its control method, and an air conditioner, which can improve the ice-melting effect of the outdoor unit and effectively avoid th...
