Water injection system, ice maker and refrigerator

Abstract

The invention discloses a water injection system, an ice maker and a refrigerator. The water injection system comprises a water storage part, a water requiring part, a water pipe assembly, a water valve and an emptying part; a waterflow channel located between the water storage part and the water requiring part is defined by the water pipe assembly; the water valve is arranged on the water pipe assembly and controls water discharging of the water storage part; the emptying part is arranged on the water pipe assembly and located above the water requiring part and comprises an airflow channel enabling the waterflow channel to communicate with the outside world, the waterflow channel communicates with the water requiring part through the waterflow channel, and water in the position, located between the emptying part and the water requiring part, of the interior of the waterflow channel completely flows into the water requiring part. Air pressure of the interior of the water injection system is balanced through the emptying part, water in the water pipe assembly is emptied in time, and the situation that water freezes in a water pipe assembly, a pipe is blocked, and electric heating wires are used is avoided. According to the scheme, the cost is low, no space is wasted, the implementation method is simple and reliable, and the water injection system can be applied to an external water source or the condition that water flows on the basis of gravity.

Description

technical field [0001] The invention relates to a water injection system, in particular to an ice maker and a refrigerator with the water injection system. Background technique [0002] At present, the ice making box is usually placed in the refrigerator to make ice, but filling the ice making box with water has always been a difficult point in the ice making system. The current existing scheme is to place the ice making box in the freezing chamber, and add water to the ice making box from the outside, which eliminates the inconvenience of water splashing inside when the ice making box is put into the refrigerator. [0003] At present, in the process of adding water to the ice making box, a certain amount of water flows into the ice making box by connecting an external water source and configuring a sensor and a solenoid valve, but the cost is high, and when adding water manually, the amount of water added cannot be accurate Control, there is a problem that too little water...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem in the prior art that the amount of water added to the ice making box is inaccurate, and the water freezes and blocks the water pipe when adding water to the ice making box, the purpose of the present invention is to provide a water injection system, an ice machine and a refrigerator
