Control method and temperature detection method of refrigerator

Abstract

The invention discloses a control method and a temperature detection method of a refrigerator. The temperature detection method of the refrigerator comprises the steps as follows: a temperature sensor is sampled for N times through a controller, N sampling values are acquired, and the N is larger than or equal to 3; and the N sampling values are converted into AD values through an AD module of the controller respectively, a maximum value and a minimum value of the N AD values are removed, then an mean value is calculated, and the temperature of a refrigeration chamber is acquired according to the mean average. According to the temperature detection method of the refrigerator, the accuracy of a detection result is improved, the refrigerator can be controlled and used conveniently, the energy consumption of the refrigerator is reduced, energy is saved, and the environment is protected. Besides, a working temperature range of the refrigerator is referred to, a universal circuit is designed, the portability is good, and the methods can be popularized and applied to a whole series of refrigerators conveniently, and the program development period is accelerated greatly.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a refrigerator temperature detection method and a refrigerator control method. Background technique [0002] At present, with the development of intelligent electronically controlled refrigerator solutions in the refrigerator industry, the operation and control of refrigerators are developing towards higher precision and more energy-saving. [0003] In traditional mechanical refrigerators, the commonly used thermostat is steam pressure thermostat. Its working principle is: when the temperature-sensing capillary senses the temperature change, the pressure of the temperature-sensing agent in the temperature-sensing capillary changes accordingly, and the non-rigid element The air box produces a small displacement with the pressure change, through the mechanical amplification mechanism, the micro switch is controlled to realize the open and stop control. [0004] The temperature-sensi...

Problems solved by technology

Its main disadvantage is that the design is not flexible, only the characteristic temperature can be selected, and each adjustment requires the cooperation of the manufacturer to develop, the development cycle is long, and it is only for a specific refrigerator, and the temperature control accuracy is poor, the start and stop range is large, and the temperature cannot be accurately controlled

In addition, traditional electronically controlled refrigerators cannot achieve real-time high-precision temperature control due to different temperature acquisition methods and software processing algorithms.

[0005] Due to the limitation of mechanical thermostat and mechanical timer, the temperature control of traditional refrigerators is only limited to specific temperature points, and it is impossible to achieve accurate temperature control.
