Safety water inlet system and method for water inlet pipe and dish washing machine with protective structure

Abstract

The invention discloses a safety water inlet system and a method for a water inlet pipe and a dish washing machine with a protective structure, wherein the water inlet pipe with the protective structure comprises a first layer of hose, a second layer of hose and an electromagnetic valve, the first layer of hose comprises a water inlet and a water outlet, the water inlet is connected with a tap water interface, and the water outlet is connected with a water inlet of the dish washing machine, the electromagnetic valve sleeves on the water inlet, the second layer of hose sleeves on the first layer of hose, the edges of ports at two ends of the second layer of hose radially extend inwards and are in sealing contact with the first layer of hose, and the second layer of hose is provided with anoverflow diversion port. According to the safety water inlet system and the method for the water inlet pipe and the dish washing machine with the protective structure, the second layer of hose is usedfor secondary protection when the first layer of hose is damaged, and the overflow water is guided out by the overflow diversion port arranged on the second layer of hose, so that the harm caused bythe leakage of tap water caused by the breakage of the water inlet pipe is effectively avoided in the water inlet process of the dish washing machine, the structure is simple and no excessive cost isneeded.

Description

technical field

[0001] The invention relates to the technical field of pipe fittings, in particular to a water inlet pipe with a protective structure, a dishwasher safe water inlet system and a method. Background technique

[0002] With the development of science and technology, more and more home users start to use dishwashers. Before washing, the dishwasher needs to introduce city tap water into the dishwasher. The pipe body is broken, which will cause tap water to flow out during the water diversion process, damage the user's kitchen facilities and even cause other serious situations such as electric leakage. The current dishwasher water inlet device mainly considers the water inlet efficiency problem, while ignoring the safety problem.

[0003] For example, the patent with the publication number CN108065884A discloses a dishwasher water inlet device and water inlet method, including: a water inlet double valve connected to an external municipal waterway, and two water o...
