Refrigerator water supply system and refrigerator

Abstract

The invention relates to the field of refrigerators, and discloses a refrigerator water supply system and a refrigerator. The refrigerator water supply system comprises a tap water inlet, a water tank and a water outlet port. The tap water inlet is connected to the water tank through a first pipeline. The water tank is connected to the water outlet port through a second pipeline. A first-stage filter device is arranged on the first pipeline. A second-stage filter device is arranged on the second pipeline. The two stages of filter devices are arranged on the water supply system, tap water entering the water supply system from the tap water inlet is repeatedly filtered and supplied to the water outlet port to be used by users after being disinfected through ultraviolet rays, and therefore it is ensured that water supplied to the users can be directly drunk, and safety and sanitary of drinking water at the water outlet port are effectively ensured. A control valve, a water pump, a pressure reduction valve and other devices are arranged in the water supply system, and therefore it can be effectively ensured that the amount of water supplied to the water outlet port is effectively controlled, and the problem of ice box overflow or incomplete water injection can be solved.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a refrigerator water supply system and a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that keeps its internal space at a constant low temperature. It is a civilian product that keeps food or other items placed in it in a constant low temperature and cold state. It is an indispensable household appliance in modern social life. [0003] With the continuous improvement of people's living standards, the requirements for refrigerators are not only satisfied with refrigeration and freezing food. In order to meet people's ever-improving living needs, refrigerators with various additional functions have appeared on the market. For example, the refrigerator is equipped with refrigerated drinking water that can directly flow out; another example is that the refrigerator is equipped with an automatic ice-making device that can provide ice cubes when user...

AI Technical Summary

Problems solved by technology

There are following defects in the above-mentioned technical scheme: (1) Since the water in the ice maker 5 and the drinking water outlet 6 is supplied by municipal tap water pressure, it is not suitable for direct drinking, even if a simple filtering device is used to filter, it still cannot ensure The water quality has reached the standard for drinking, and there are health risks; (2) The entire water supply system is directly supplied by the tap water system, and the entire system is under pressure for a long time, which increases the possibility of system leakage and pipeline bursts, resulting in damage to the water supply system. The service life is shortened, which affects the use effect of the refrigerator; (3) The water pressure of the municipal water supply is difficult to maintain constant, and the fluctuation of the water pressure leads to the uncontrollable water injection volume, which causes the ice machine 5 to overflow the ice box or the ice box is not filled with water

There are following defects in the above-mentioned technical solution: (1) the water in the water tank 21 needs to be added manually, which causes inconvenience to the user; The air is isolated, and the stored water is in direct contact with the outside air, causing the stored water to be polluted twice, posing health risks
