Refrigerator with water supply function

Abstract

The invention provides a refrigerator with a water supply function. The refrigerator comprises a refrigerator body in which a storage compartment is defined; a door body which is arranged on the front side of the refrigerator body and is used for opening and closing the storage compartment, a water taking opening being formed in the door body; a refrigeration system which forms compression type refrigeration cycle through a compressor, a condenser, a throttling device and an evaporator, and is configured to supply cold to the storage compartment; and a water supply system which is arranged in the refrigerator and is configured to supply water to the water taking opening, wherein the water supply system comprises a heat exchanger configured to preliminarily heat water of the water taking opening through heat released by the condenser. According to the refrigerator with the water supply function, heat produced by the condenser when the refrigeration system supplies cold to the storage compartment is transferred to the water in the heat exchanger, so that the water is preliminarily heated by using waste heat; and therefore, the utilization efficiency of the heat is improved, and electric energy consumption for heating is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator with a water supply function. Background technique [0002] With the continuous improvement of people's living standards, the functional requirements for household appliances such as refrigerators are also getting higher and higher. At present, some high-end refrigerators also have the function of supplying drinking water. For example, a water intake is set on the refrigerator door to supply hot water or ice water according to the needs of users. [0003] The structure of the existing high-end refrigerator door body for hot water is mostly a hot water bottle with an electric heating tube installed in the refrigerator door body. After the cold water enters the hot water tank, the electric heating tube works. When the temperature sensor in the hot water tank detects that the water temperature reaches When setting the temperature, cut off the power su...

AI Technical Summary

Problems solved by technology

[0004] The temperature of the hot water in the hot water tank is mostly around 85 degrees, while the temperature in the refrigerator is between 2 and 8 degrees. Due to the limitation of the thickness of the door body, the heat preservation of the hot water tank cannot be very thorough, so the hot water The refrigerator is quite a constant heat source in the refrigerator, so it will bring two main problems: on the one hand, it will cause uneven temperature in the refrigerator, and the compressor needs to be frequently turned on and off to ensure the temperature in the refrigerator, and the energy consumption of the whole machine is too high ; On the other hand, the water temperature in the hot water tank drops too fast, and the heating pipe needs to be heated frequently to keep the temperature constant

These two problems will lead to higher energy consumption of the refrigerator
