Problems solved by technology

When the indoor fan of the air conditioner is working, white powder will be blown out from the air duct, affecting the user experience
[0003] Some electric heating surfaces use Teflon (polytetrafluoroethylene) coating to prevent the electric heating surface from being corroded, but it will cause environmental pollution during the production and processing of Teflon coating
At the same time, when the electric heating is in an abnormal working state (such as dry burning), the surface temperature is too high, the Teflon coating will start to decompose and deteriorate, and produce toxic substances, which will cause harm to the health of users. increase the cost of the product

Embodiment Construction

[0045] In order not to affect the user's cooling experience, the electric heater is usually not turned on in the cooling or dehumidification mode. Under the guidance of traditional ideas, those skilled in the art use the structure or material design of the electric heater itself as a starting point to avoid its surface from being corroded.

[0046] The invention breaks through the shackles of traditional ideas, and proposes a new control method for the air conditioner, which is used to prevent the surface of the electric heater of the air conditioner from being corroded. figure 1 is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention. see figure 1, the control method includes: when the first preset condition, the second preset condition or the third preset condition is met, turn on the electric heater to evaporate the condensed water on the surface of the electric heater through the heat generated by the electric heat...

Abstract

The invention relates to an air conditioning device and a control method thereof. The control method is used for preventing the surface of an electric heater of the air conditioning device from beingcorroded and comprises steps as follows: when a first preset condition, a second preset condition or a third preset condition is met, the electric heater is started, condensate water on the surface ofthe electric heater is evaporated through heat produced by the electric heater until the starting time of the electric heater reaches second preset duration. The first preset condition is that cumulative duration of operation of a compressor of the air conditioning device at frequency higher than or equal to first preset frequency in a refrigeration or dehumidification mode reaches first preset duration; the second preset condition is that when temperature of the indoor environment reaches the preset temperature in the refrigeration or dehumidification mode, breaking halt is required, or whena shutdown signal for indicating the air conditioning device to stop operating is received, normal shutdown is required; the third preset condition is that the air conditioning device is required tobe switched in a heating mode and the compressor stops running. Therefore, the surface of the electric heater of the air conditioning device can be prevented from being corroded, and the air conditioning device is safe, healthy, environmentally friendly and low in cost.

Description

technical field [0001] The invention relates to common electric appliances, in particular to an air conditioner and a control method thereof. Background technique [0002] During the cooling process of the air conditioner, a large amount of condensed water will be generated inside the evaporator, and the electric heating of the air conditioner is installed inside the evaporator. When the air conditioner is used in summer, condensed water will adhere to the electric heating surface. If the condensed water on the electric heating surface is not treated in time, the electric heating surface will be corroded after long-term use, resulting in white powder, such as Al 2 o 3 . When the indoor fan of the air conditioner is working, white powder will be blown out from the air duct, affecting the user experience. [0003] Some electric heating surfaces use Teflon (polytetrafluoroethylene) coating to prevent the electric heating surface from being corroded, but it will cause environ...
