Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] figure 1 It shows a flow chart of a control method for air conditioning auxiliary electric heating according to an embodiment of the present invention, including the following steps:

[0016] S102, the zero-crossing signal detection module detects the zero-crossing time of the power signal;

[0017] S104, the main control module controls the conduction time of the switch module according to the zero-crossing time to adjust the voltage applied to both ends of the auxiliary electric heating module of the air conditioner.

[0018] In this embodiment, the real-time control of the operating voltage at both ends of the auxiliary electric heater of the air conditioner realizes automatic control of its heating power, improves the energy saving performance of the air conditioner during heating operation, improves the comfort of the us...

Abstract

The invention provides control method and device for assistant electrical heating of an air conditioner. The method comprises the following steps: an over-zero signal detecting module detects the over-zero time of electric source signals; and a main control module controls the conducting time of a switch module according to the over-zero time to adjust voltage applied to both ends of an assistantelectrical heating module of the air conditioner.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a control method and device for auxiliary electric heating of an air conditioner. Background technique [0002] The inventor found that the auxiliary electric heating control mode of the air conditioner in the prior art can only simply control the two states of on or off, and cannot continuously control the heating power of the auxiliary electric heating, resulting in low efficiency of the air conditioner, which in turn leads to a comfortable user experience Sex is poor. Contents of the invention [0003] The purpose of the present invention is to provide a control method and device for air-conditioning auxiliary electric heating, which can solve the control mode of air-conditioning auxiliary electric heating in the prior art, which can only simply control two states of on or off, and cannot continuously control the auxiliary electric heating. The heating power of the heating le...
