Embodiment 1

[0048] Example 1, such as figure 1 As shown, an air-conditioning control method of the present invention includes the following steps:

[0049] S1: Detect the running current of the air conditioner in real time, wherein the method of detecting the running current of the air conditioner is well known to those skilled in the art, and will not be repeated here.

[0050] S2: judging whether the current current value is less than the first current threshold; if yes, proceed to step S3; if not, stop the compressor for current protection.

[0051] S3: Determine whether the current current value is smaller than the second current threshold; if yes, proceed to step S4; if not, reduce the operating frequency of the compressor.

[0052] S4: Determine whether the current current value is less than the third current threshold; if yes, the compressor continues to work normally; if not, the compressor maintains the current operating frequency and prohibits frequency up.

[0053] In the abo...

Embodiment 2

[0056] Based on Embodiment 1, for the first current threshold, the second current threshold, and the third current threshold, the specific content is as follows:

[0057] Both the first current threshold and the second current threshold are numerically based on the third current threshold.

[0058] The third current threshold, also known as the current value for prohibiting up-converting, is a reference value for judging whether the compressor is working normally based on the reliability data obtained mainly through the specifications of the components in the air conditioner and experimental conditions.

[0059] The second current threshold, also known as the down-frequency current value, in real life, according to the different specifications and models of the air conditioner, the second current threshold is taken as 1.05~1.15 times of the third current threshold to determine whether to reduce the operation of the compressor Frequency reference value.

[0060] The first curr...

Embodiment 3

[0061] Embodiment 3, as the specific description to the method in embodiment 1, as figure 2 shown;

[0062] In the judgment process of step S2 in Embodiment 1, when the judgment result is no, that is, when the current current value is greater than or equal to the first current threshold, the following steps are performed:

[0063] S201: Record the current operating frequency of the compressor, and stop the compressor.

[0064] Among them, the memory of the air conditioner records and stores the current operating frequency of the compressor. After the recording is completed, the air conditioner automatically cuts off the compressor running switch, thereby avoiding the phenomenon that the air conditioner is burned out due to excessive current.

[0065] S202: Determine whether the current current value is smaller than the fourth current threshold; if not, proceed to step S202; if yes, proceed to step S203.

[0066] Wherein, in terms of numerical value, the fourth current thres...

Abstract

The invention provides a control method for an air conditioner. The control method comprises the steps that 1, running currents of the air conditioner are detected in real time; 2, whether a current current value is smaller than a first current threshold value or not is judged, if yes, the step 3 is conducted, and if not, a compressor is stopped; 3, whether the current current value is smaller than a second current threshold value or not is judged, if yes, the step 4 is conducted, and if not, the running frequency of the compressor is decreased; 4, whether the current current value is smallerthan a third current threshold value or not is judged, if yes, the compressor continues to normally work, and if not, the compressor keeps the current running frequency and prohibits frequency increasing. According to the control method for the air conditioner, when currents are abnormal in the running process of the air conditioner, the compressor is controlled by setting a current threshold value on the running currents of the air conditioner according to the condition that an actual current value reaches the current threshold value, the protection effect on the air conditioner currents is achieved, therefore, the condition that the air conditioner is burnt out due to the fact that the currents suddenly fail is avoided, air conditioner running is guaranteed to the maximum limit when thecurrents are abnormal, and use can not be influenced for users.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an air conditioner control method. Background technique [0002] At present, household appliances bring more and more convenience to people, and also improve the quality of life. However, during the use of household appliances, due to some circuit failures in the household circuit, the current suddenly increases. At this time, the sudden increase in current not only affects the service life of the household appliance, but may even cause the appliance to burn out. cause losses to users. Taking an air conditioner as an example, the present invention provides a current protection method for the air conditioner, through which the air conditioner will not be burned out due to sudden current failure during operation. [0003] The patent document with the application number 201310248544.5 discloses a control method of an air conditioner, including: S1: In the cooling operation mode...
