Embodiment Construction
[0033] The present application is further described in conjunction with the following examples.
[0034] Such as Figure 1 to Figure 4 , an anti-freezing device for an external unit of an air conditioner, which is applied to the air inlet 9 of the external unit of the air conditioner, and includes an air inlet grill 1 arranged on the air inlet 9, and the air inlet grill 1 is made of a heating element that can be heated by electricity Hotline 2 braided formation. The anti-freezing device for the outdoor unit of the air conditioner is applied to the air inlet 9 of the outdoor unit of the air conditioner. By modifying the air inlet grill 1, the heating wire 2 that can be energized is woven to form the air inlet grill 1. 1 After power on, it can generate heat on the air intake grille 1, heat and melt the frost on the air intake grille 1, which has the effect of anti-freezing, and prevents frost from blocking the air intake grille 1, resulting in insufficient air intake and affect...

The invention relates to an anti-freezing device for an air conditioner external unit, and applies to an air inlet of the air conditioner external unit. The anti-freezing device comprises an air inletgrille arranged on the air inlet, and the air inlet grille can be formed by weaving of a heating wire which can be electrified and heated. According to the anti-freezing device for the air conditioner external unit, the anti-freezing device for the air conditioner external unit applies to the air inlet of the air conditioner external unit, and through the transformation of the air inlet grille, the electrified heating wire is woven into the air inlet grille; after powering on of the air inlet grille, the heat generated on the air inlet grille can be made to heat and melt frosting on the air inlet grille, the effect of anti-freezing is achieved, and the insufficient air intake and the influence of the heat exchange efficiency due to blocking of the air inlet grille by the frosting are avoided; and the invention further provides an anti-freezing control method of the air conditioner external unit and by using the anti-freezing device for the air conditioner external unit and an air conditioner comprising the anti-freezing device for the air conditioner external unit.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an anti-freezing device for an external unit of an air-conditioner, and also relates to an anti-freezing control method for an external unit of an air-conditioner realized by using the anti-freezing device for an external unit of an air-conditioner, and to an anti-freezing control method for an external unit of an air-conditioner. Air conditioning for freezers. Background technique [0002] When the air conditioner works at low temperature, when the air inlet grille of the air conditioner external unit is frosted, the hot refrigerant can only pass through the heat exchanger of the air conditioner external unit when the air conditioner external unit defrosts, and the heat exchanger and the air inlet air conditioner Therefore, there is no heat source to melt the frost on the air intake grill, and as time goes by, the frost on the air intake grill will accumulate, a...
