Refrigerating system of ice maker

Abstract

The invention relates to a refrigerating system of an ice maker. The refrigerating system of the ice maker comprises an ice tray for making ice, a heat exchange sleeve, a compressor, a four-way reversing valve, a condenser, an auxiliary heater, a fan motor, a filter, a throttling mechanism, a one-way valve, a water feeding mechanism, a water feeding equalizer and an electromagnetic valve. According to the refrigerating system of the ice maker provided by the invention, the water feeding equalizer is arranged between the water feeding mechanism and the electromagnetic valve, so that a water flow is uniformly distributed into channels distributed on a large horizontal plane. According to the refrigerating system of the ice maker provided by the invention, the four-way reversing valve is arranged in the refrigerating system of the ice maker and is used for achieving mutual switching between a refrigerating system loop I and a refrigerating system loop II, so that the ice removing efficiency of the ice maker is improved, the 24-hour ice production yield of the ice maker is greatly improved, and the refrigerating system of the ice maker is more energy-efficient.

Description

technical field [0001] The invention relates to the technical field of ice machines, in particular to a refrigeration system of an ice machine. Background technique [0002] At present, the current ice machine is not equipped with a four-way valve and a one-way valve, and the gas-liquid separator used is simple in structure and low in efficiency. During the ice making process, the compressor is prone to liquid shock and damage; The lubricating oil is often supplied together with the flow of the refrigerant, and stored in a large amount in the gas-liquid separator, which is not conducive to the effective lubrication of the compressor under severe working conditions, and the damage rate of the compressor is obviously abnormal; there is also capillary throttling In desperation, the existing ice machine sticks the capillary on the suction pipe. [0003] The current ice machine generally suffers from low deicing efficiency, especially when deicing at low ambient temperature, the...

AI Technical Summary

Problems solved by technology

During this rough deicing process, the condenser is still under high pressure, and a large amount of refrigerant is accumulated in it, resulting in deicing operation in a state of lack of refrigerant, which seriously affects the deicing efficiency

In addition, in the existing ice machine with throttling thermal expansion valve, the thermal expansion valve gradually opens in the middle and late stages of deicing operation, and part of the refrigerant discharged from the compressor will enter the ice tray through the condenser, filter and thermal expansion valve. After the refrigerant passing through the condenser enters the ice tray, it will seriously affect the deicing efficiency, and even cause deicing failure, which will have an extremely serious impact on the normal operation of the ice machine

[0004] There are many problems in the ice machine under the existing technology, the market has a large amount of maintenance, and the general energy consumption is relatively high, which needs to be improved urgently
