Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] figure 1 It is a schematic flow chart of a control method for reliable operation of electric heating of an air conditioner in an embodiment of the present invention. The above method includes:

[0029] S102, turn on the electric heating and acquire the temperature rise rate of the inner disk.

[0030] Before turning on the electric heating, it is necessary to control the opening of the air guide door, the compressor and the indoor fan.

[0031] In the heating mode, open the air guide door, turn on the compressor, turn on the indoor fan after the anti-cold wind mode is over, and then check whether the electric heating opening condition is met, and turn on the electric heating when it is satisfied. Optionally, if the temperature of ...

Abstract

The invention provides a control method and device for reliable operation of electric heating of an air conditioner and the air conditioner. The method comprises the steps that electric heating is started, and the temperature rising rate of an inner disc is obtained; whether the temperature rising rate is greater than or equal to a preset rate threshold or not is determined by comparison; and. if yes, electric heating is controlled to be stopped. According to the method, the temperature rising rate of the inner disc is obtained after electric heating is started, and the electric heating is controlled to be stopped under the condition that the temperature rising rate is greater than or equal to the rate threshold value, so that the high-temperature deformation of a plastic part and a fire hazard caused by dry burning of electric heating under the condition that an air guide door is not normally opened or an inner draught fan is not normally operated are avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for controlling the reliable operation of electric heating of an air conditioner and an air conditioner. Background technique [0002] In order to improve the low-temperature heating effect, the air conditioner usually adds an electric heating function. Due to the particularity of electric heating, the control logic of the controller and the operation mode of the fan must match the electric heating. If the matching is not good, the air conditioner may not be able to operate safely and effectively when the electric heating is turned on. [0003] When the air conditioner is heating and running, if the conditions for turning on the electric heating are met, the electric heating needs to be turned on only after the air guide door is opened. The opening of the air guide door needs to be driven by a stepping motor. If the stepping motor is damaged, slipped...
