Car refrigerator control method, system and equipment and car refrigerator

Abstract

The invention discloses a car refrigerator control method. The car refrigerator control method comprises the steps of acquiring the input voltage of a car refrigerator when responding to an enabled instruction; judging whether the input voltage is less than the preset minimum threshold voltage or not; if yes, starting power-off protection until the input voltage is greater than the preset enabledvoltage; if not, judging that the car refrigerator operates normally; acquiring the dip angle between the car refrigerator and the horizontal plane when the starting voltage is greater than the minimum threshold voltage, and judging whether the dip angle is greater than the preset dip angle threshold value or not; if yes, starting power-off protection until the dip angle is less than or equal to the dip angle threshold value; and if not, judging that the car refrigerator operates normally. The invention further discloses a car refrigerator control system, car refrigerator control equipment andthe car refrigerator. Through the car refrigerator control method provided by the embodiment of the invention, a compressor can be protected when the car refrigerator is tilted, and meanwhile, the car refrigerator is protected at the voltage below level.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a control method, system, and device for a vehicle-mounted refrigerator, and the vehicle-mounted refrigerator. Background technique [0002] With the development of society, more and more users install car refrigerators in their cars. The car refrigerators are installed and fixed on the car, and the car will encounter various situations during driving, such as bumps, sudden acceleration, sudden braking, and sharp turns. Wait. When the car refrigerator changes with the movement state of the car, because the compressor motor is hung in a sealed metal container with 3 shock absorbing springs, there is a danger of decoupling if it is tilted, and the compressor oil in the compressor will be damaged. It will flow into the pipeline, cause damage to the compressor, and affect the circulation process of the refrigerator at the same time, and the lack of lubrication of the compresso...

AI Technical Summary

Problems solved by technology

When the car refrigerator changes with the movement state of the car, because the compressor motor is hung in a sealed metal container with 3 shock absorbing springs, there is a danger of decoupling if it is tilted, and the compressor oil in the compressor will be damaged. It will flow into the pipeline, causing damage to the compressor and affecting the circulation process of the refrigerator, and the lack of lubrication of the compressor oil in the compressor will cause loud noise

In addition, the driving motor of the car refrigerator can only work normally within a certain voltage range. If the power supply voltage is too low, it will easily cause the winding coil to burn out, thus affecting the normal operation of the car refrigerator.
