Refrigerator waterway control system with automatic circular water supply and refrigerator

Abstract

The invention relates to the technical field of household appliance rail transits, in particular to a refrigerator waterway control system with automatic circular water supply. The refrigerator waterway control system comprises a water injection waterway, a circular waterway and a functional waterway, wherein the water injection waterway, the circular waterway and the functional waterway are sequentially connected to form a loop, the water injection waterway comprises a tap water power supply solenoid valve, a circular solenoid valve and a water level sensor located in a water tank, when the fact that the value of the water level in the water tank is below the lowest limiting value of the water level is detected by the water level sensor, the circular solenoid valve and the tap water power supply solenoid valve are opened, and when the fact that the value of the water level in the water tank is equal to or larger than the lowest limiting value of the water level is detected by the water level sensor, the system automatically closes the circular solenoid valve and the tap water power supply solenoid valve. The invention further discloses a refrigerator provided with the refrigerator waterway control system with automatic circular water supply. Due to the water injection waterway, the circular waterway and the functional waterway, the loop in the refrigerator is kept to be circulated and purified continuously, the mouthfeel of cold drinking water is kept, and the refrigerator waterway control system is high in safety and stability.

Description

Technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator waterway control system with automatic circulating water supply and a refrigerator. Background technique [0002] With the development of smart home appliances, people’s functional requirements for refrigerators are not limited to refrigerated and frozen foods. Therefore, refrigerator manufacturers have also developed various additional functions, such as bar counters, ice machines, cold drinking water, etc. Device. [0003] At present, the refrigerator water system with ice maker and drinking water is a simple one-way flow water system that filters the water from the water tank and pumps it directly into the ice tray of the ice maker or to the drinking water outlet. The water tank is installed on the hidden door, the ice maker and the drinking water outlet are installed on the freezing door, and the water pipe is connected to the box body through the lower ...

AI Technical Summary

Problems solved by technology

[0005] 1. When you do not drink cold water or make ice for a long time, the residual water in the water pipe exposed outside the foam layer of the box will rise due to the influence of the ambient temperature. When you drink cold water again, the residual water in the pipe will be taken out first. The temperature of the water is higher, and the cold water cannot come out immediately

[0006] 2. If the water remaining in the pipeline does not drink or make ice for a long time due to people going out or other reasons, the pipeline is a fully enclosed space, and the water is easy to breed bacteria, which poses a safety hazard and affects the taste

In the existing rail transit platform door control system, the central control device adopts a large-scale PLC to design the door unit controller; the interface programming is inconvenient and other disadvantages
