Problems solved by technology

[0014] However, in the above structure, even when the motor 103 is driven, the cooling fan 104 will not be able to rotate freely if there is a head wind blowing from the outside with a pressure greater than that generated when the cooling fan 104 is in operation.
In addition, since the anti-reversal device 105 protrudes outside, it is not beautiful in appearance.

Embodiment Construction

[0033] Next, the outdoor unit provided with the device for preventing the rotation shaft of the motor from reversing according to the present invention will be described in detail with reference to the accompanying drawings.

[0034] Figure 4 It is a schematic view of the outdoor unit with the device for preventing the rotation axis of the motor from reversing according to the present invention. As shown in the figure, the refrigerant circulation process of the present invention is: the compressor 400 compresses the gaseous refrigerant flowing in from the indoor unit through the refrigerant pipe into a high-temperature / high-pressure refrigerant; the refrigerant compressed by the compressor 400 is cooled by the condenser 401; The cooled refrigerant is transported to the indoor unit through the refrigerant pipe. Here, in order to improve the cooling efficiency of the refrigerant, the cooling fan 402 is installed on the rotating shaft 404 of the driving motor 403 and driven to ...

Abstract

The invention discloses an outdoor set, which is characterized by the following: setting motor and cooling fan to activate the cooling fan; forcing the outside air to pass through the condenser; setting one-way clutch on the rotary shaft of activation motor; revolving the rotary shaft toward the activated direction of activation motor; preventing the inversion of rotary shaft; setting the one-way clutch in the activation motor case or on the rotary shaft. The invention prevents the difficult prediction current due to power generation elementary for activation circuit, which removes the projection part to display better attractive appearance.

Description

technical field [0001] The invention relates to an outdoor unit of an air conditioner. In particular, it relates to an outdoor unit having a motor rotation shaft reversing prevention device which prevents the cooling fan of the outdoor unit from reversing, so that the cooling fan can be rotated in the fastest time in the driving direction of the driving motor at the initial stage of driving the outdoor unit. Background technique [0002] Generally speaking, the working process of an air conditioner is as follows: the compressor compresses the gaseous refrigerant into a high-temperature / high-pressure refrigerant; the gaseous refrigerant compressed into a high-temperature / high-pressure state is cooled in the condenser; The refrigerant in the evaporator is converted into a low-temperature / low-pressure refrigerant; in the evaporator, through heat exchange, it absorbs the heat around the evaporator, thereby reducing the temperature of the surrounding air. [0003] Air conditione...
