Top-outlet air conditioner outdoor unit, air conditioner and control method of air conditioner

Abstract

The invention relates to an air conditioner, in particular to a top-outlet air conditioner outdoor unit and the air conditioner. The air conditioner comprises the top-outlet air conditioner outdoor unit and a controller, wherein the controller intensively controls assemblies of the air conditioner. The top-outlet air conditioner outdoor unit comprises an air outlet, wherein a top cover is arranged on the air outlet, a fan is arranged below the top cover, heating wires are arranged on the periphery of the fan, and a rain sensor and a temperature sensor are arranged on the top cover. The heating wires, the rain sensor and the temperature sensor are all intensively controlled by the controller of the air conditioner. The top-outlet air conditioner outdoor unit and the air conditioner are simple in structure, and the heating wires are simply needed to be additionally fixed on the existing top cover structure. In addition, air outlet resistance of the air conditioner outdoor unit cannot be increased, the air amount of the air conditioner outdoor unit cannot be reduced, air conditioner power increase is not much, and air conditioner energy efficiency cannot be reduced by too much. After the top cover of the air conditioner is additionally arranged, the air conditioner can normally operate in serious working conditions at rainy days and snowy days in winter, icing on the periphery of a wind girder is avoided, accordingly the fan cannot be frozen or damaged, the air conditioner is stable in operation, and operation reliability of the whole air conditioner is improved.

Description

[0001] technical field [0002] The invention relates to an air conditioner, in particular to an outdoor unit of the air conditioner and an air conditioner that push out air. Background technique [0003] In the air conditioner with top air outlet in the prior art, the entire air supply system is exposed to the outdoor side. In winter, if it rains when the temperature is very low, the top of the entire air conditioner will freeze. If the icing continues, it may cause the fan to touch the ice layer, break the fan, cause the machine to malfunction, and even cause a safety accident. [0004] In order to solve this problem now in the prior art, the general way is to make a snow cover for the air conditioner, so that the wind is blown out sideways. Adding a snow cover can solve the problem of freezing or cracking of the fan when it rains or snows in winter, but after adding this kind of snow cover, firstly, the cost increases a lot, and secondly, it adds a lot of air to the air ...

AI Technical Summary

Problems solved by technology

[0005] The present invention overcomes the above-mentioned defects. The present invention designs a top cover structure that can automatically de-ice, which can automatically de-ice the machine in the harsh conditions of rain and snow in winter, and solves the problem of the machine running in winter. It will not increase a lot of cost, nor will it increase the resistance of the machine to the wind, and will not affect the energy efficiency of the machine too much
