Embodiment Construction

[0028] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] The invention provides an outdoor unit defrosting device.

[0030] refer to Figures 1 to 3 , figure 1 It is a structural schematic diagram of the installation state of the outdoor unit defrosting device of the present invention; figure 2 for figure 1 Partial explosion diagram in ; image 3 for figure 2 The partial enlarged schematic diagram of A. This embodiment provides an outdoor unit defrosting device, and the indoor unit defrosting device is arranged on an air conditioner. Those skilled in the art know that the air conditioner includes an indoor unit (not shown in the figure), an outdoor unit 1 , a compressor 2 and a four-way valve (not shown in the figure). When the air conditioner is in the heating mode, the four-way valve connects the input end of the compressor 2 to the outdoor unit 1, and con...

Abstract

The invention discloses an outdoor unit defrosting device and an air conditioner with the same. The outdoor unit defrosting device comprises a heat exchange module and an air supply module. The heat exchange module is arranged at the position of a refrigerant conveying pipe between an exhaust port of an air conditioner compressor and a four-way valve and used for controlling heat exchange between the refrigerant conveying pipe and outside air. The air supply module comprises an air supply pipe fitting and a fan. The air supply pipe fitting comprises an air inlet and an air outlet, the air inlet of the air supply pipe fitting corresponds to the heat exchange module, the air outlet of the air supply pipe fitting corresponds to a fin of an outdoor unit, and the fan controls air having undergone heat exchange with the heat exchange module to flow into the air supply pipe fitting through the air inlet. Remaining heat generated in the air conditioner running process is conveyed to the fin of the outdoor unit, and thus the outdoor unit defrosting effect is achieved. The shortcoming that the use of the air conditioner by users is affected due to noise resulting from frequent starting and shutdown is overcome. According to the outdoor unit defrosting device, the heating capacity of the air conditioner is not reduced in the defrosting process, and thus the heating efficiency is guaranteed.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an outdoor unit defrosting device of the air conditioner and the air conditioner. Background technique [0002] At present, when most heat pump air conditioners operate for heating under high-humidity conditions, the evaporation temperature of the refrigerant decreases with the decrease of the outdoor ambient temperature. When the evaporation temperature of the refrigerant is lower than 0°C, the surface of the outdoor heat exchanger is prone to frost. As the degree of frosting increases, the heating effect of the air conditioner also decreases. When the air conditioner is severely frosted, it is necessary to stop heating and enter the full defrosting working state. This not only affects the user's comfort in using the air conditioner, but also the noise caused by frequent start and stop of the air conditioner at night will affect the sleep quality of the user. [0003] In order...
