Problems solved by technology
[0002] At present, most of the common cleaning systems for refrigerators are manually controlled. Whether it is inflation, deflation or evacuation, the operator needs to perform manual operations on site. The buttons on the operation panel are redundant, which is prone to problems such as misoperation and poor control accuracy. It seriously affects the cleaning effect of the refrigerator, and it also consumes a lot of time for the operator. It is even more difficult to work at the same time for multiple refrigerator stations.

Embodiment Construction
[0011] Such as figure 1 As shown, an automatic cleaning system for a refrigerator includes an automatic inflation system, an automatic deflation system, an automatic evacuation system and an electrical control system 22 .
[0012] The automatic inflation system includes piston pilot solenoid valves 13, 14, differential pressure piston pilot high pressure resistant solenoid valves 11, 12, one end of the piston pilot solenoid valves 13, 14 is connected to a high pressure regulating valve 18 through a high pressure pipeline, and the piston pilot type The other ends of solenoid valves 13 and 14 are connected to differential pressure piston pilot high pressure resistant solenoid valves 11 and 12 through high pressure pipelines. Piston pilot solenoid valves 13 and 14 are normally open valves, and the other end of high pressure regulating valve 18 is connected to inflation joint 19 , Piston pilot-operated solenoid valves 13, 14 and differential pressure piston pilot-operated high-pre...

The invention discloses an automatic cleaning system for a refrigerator. The automatic cleaning system comprises an automatic inflation system, an automatic deflation system, an automatic evacuation system and an electric control system, and is novel in concept, reasonable in process and advanced in design. A piston pilot type solenoid valve and a pressure gradient piston pilot type high-pressure-resistant solenoid valve are applied in a combined manner, and automatic quick high-precision inflation under high pressure and vacuum sealing property in the vacuum state are realized in the inflation system and the evacuation system through different working modes of the two valves, so that the current problems of large cleaning workload, low cleaning work efficiency, high maintenance cost and the like of the refrigerator are radically solved.
Description
technical field [0001] The invention relates to the technical field of container product cleaning, in particular to an automatic cleaning system for a refrigerator. Background technique [0002] At present, most of the common cleaning systems for refrigerators are manually controlled. Whether it is inflation, deflation or evacuation, the operator needs to perform manual operations on site. The buttons on the operation panel are redundant, which is prone to problems such as misoperation and poor control accuracy. Seriously affect the cleaning effect of the refrigerator, and also greatly consume the time of the operator, and the operation of multiple refrigerator stations is a large workload and cannot work at the same time. There is an urgent need to provide an automatic cleaning technology for refrigerators that can make up for the above determinations and improve cleaning efficiency. Contents of the invention [0003] The object of the present invention is to provide an ...
