Low-cost knob type refrigerator computer control system

Abstract

The invention discloses a low-cost knob type refrigerator computer control system. A refrigerator comprises a case, a refrigeration system and a computer control system body. The refrigeration system comprises a compressor, a fan and an evaporator. The computer control system body comprises a computer control panel, a quick freezing key, a gear adjusting knob, an indicating lamp set and a temperature sensing probe for sensing the temperature of the evaporator. The computer control panel is located and internally arranged in the case. The quick freezing key, the gear adjusting knob, the indicating lamp set and the temperature sensing probe are all electrically connected to the computer control panel, and the computer control panel correspondingly controls starting, stopping, and operating frequency adjustment of the compressor and work of the indicating lamp set. By means of the refrigerator, precise control over the refrigerator temperature adjustment can be achieved, a conventional freezing mode and a quick freezing mode are achieved, and the two work modes can be freely switched. User needs are met, food in the refrigerator is kept fresh, and power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerators, and specifically provides a low-cost knob type refrigerator computer control system. Background technique [0002] At present, the freezer on the market includes mechanical freezer and computer freezer, wherein, the mechanical freezer uses a mechanical thermostat to control and adjust the temperature of the freezer, and the computer freezer uses a computer controller to control and adjust the temperature of the freezer. However, after investigation, it is found that the existing refrigerators have the following disadvantages: 1) Most of the existing computer refrigerators belong to high-end models, which are not only expensive, but also relatively complicated to operate, and do not meet the operating habits of most users. The market is still dominated by mechanical freezers. 2) Although the existing mechanical refrigerators are affordable, the mechanical temperature control method has a la...

Problems solved by technology

However, after investigation, it is found that the existing refrigerators have the following disadvantages: 1) Most of the existing computer refrigerators belong to high-end models, which are not only expensive, but also relatively complicated to operate, and do not meet the operating habits of most users. The market is still dominated by mechanical freezers

2) Although the existing mechanical refrigerators are affordable, the mechanical temperature control method has a large error in temperature control, which has an adverse effect on food storage and energy consumption; in addition, the existing mechanical refrigerators still have temperature drift and the life of the indicator Disadvantages such as short, non-stop, non-start, etc., resulting in a large number of customer complaints and after-sales maintenance

3) Most of the existing mechanical freezers do not have a quick-freezing function. If a quick-freezing function is required, an additional mechanical timer needs to be added, which will double the cost of the freezer
