Embodiment Construction

[0012] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that such embodiments do not limit the scope of the present invention.

[0013] (Example)

[0014] Such as figure 1 As shown, the ambient temperature collection method of the present invention divides the collection method of the ambient temperature into the following four different time periods according to the working status of the high-current components.

[0015] [α time period]

[0016] During this period of time, the high-current components do not work, and the ambient temperature is not affected by the heat of the high-current components. Therefore, at this time, the thermistor actually detects the ambient temperature, and the semiconductor chip samples the detected ambient temperature in real time. The ambient temperature data A1 obtained by real-time sampling is used as the temperature value C1 for temperature control, tha...

Abstract

The invention provides an environmental temperature acquisition method, which performs different acquisition and processing on the temperature performing temperature control in the set time before, in and after the work of a high-current component and in different time periods after the set time after the work to achieve reasonable effect and avoid incorrect sampling temperature so as to correctly control the temperature in store, avoid the temperature in store in an abnormal state and improve the temperature control performance of a refrigerator.

Description

technical field [0001] The invention relates to an ambient temperature collection method, in particular to an ambient temperature collection method that can be used in household appliances closely related to the ambient temperature, such as refrigerators. Background technique [0002] Refrigerators control the temperature in refrigerators, freezers, etc. according to changes in the ambient temperature, so it is necessary to accurately collect the ambient temperature. The thermistor used to measure the ambient temperature is generally installed on the control substrate, and then the ambient temperature data detected by the semiconductor chip is read in real time. [0003] However, there are also some high-current components installed on the control substrate, and the temperature of these high-current components will rise during operation, which will affect the detection value of the thermistor, so that the correct ambient temperature cannot be obtained, which affects the temp...
