Water supply device, refrigerator and ice maker with the same

Abstract

The invention provides a water supply device, a refrigerator and an ice maker with the same. The water supply device comprises a water storing part and a water pumping part; the water pumping part is provided with a water pump; the water inlet end of the water pump is connected with a water pumping pipeline; the water outlet end of the water pump is connected with a water supply pipeline; the water pumping pipeline is connected with the internal part of the water storing part; and a one-way valve is arranged in the water pumping pipeline. A one-way valve is arranged in the water pumping pipeline connected with the water bump according to the water supply device provided by the invention, so the one-way valve can respond to the change of working state of water pump immediately without being influenced by other factors. Therefore, the on and off of water in the water pumping pipeline is more effectively and accurately implemented for preventing from over-flowing of water. The refrigerator and the ice maker provided by the invention are provided with the above water supply system, which can effectively prevent water from overflowing out of the ice maker. Consequently, the safety and reliability of ice making system of the refrigerator and the ice maker are improved.

Description

technical field [0001] The invention relates to the field of ice making, in particular to a water supply device, a refrigerator and an ice maker having the same. Background technique [0002] The traditional ice-making method is to fill the ice-making container with water, and then put it into the freezer, freezer and other equipment to freeze and make ice. However, with the advancement of technology, the water supply device is used to automatically supply the ice-making container during the ice-making process. Water supply, due to the limited capacity of the ice maker, in order to prevent excessive water supply from overflowing, the water supply device is usually equipped with a flow limiting function. For example, in the utility model patent document with the application number of 200320110454.1, a water spray overflow waterway structure of an ice machine is disclosed, which includes a water storage tank, placed in the water tank of the ice machine, and a water outlet hole...

Problems solved by technology

However, when the liquid level of the water tank fluctuates unstable, for example, the user accidentally collides with the ice machine, or the ice machine is subjected to other external forces to cause the liquid level of the water tank to fluctuate, it will drive the float valve to rise and fall irregularly, thereby affecting Normal movement to the check valve destabilizes the water supply to the ice machine
