Refrigerator drain pipe freezing and blocking monitoring system

Abstract

The invention discloses a refrigerator drain pipe freezing and blocking monitoring system. The refrigerator drain pipe freezing and blocking monitoring system comprises a drain pipe freezing monitoring device; the drain pipe freezing monitoring device comprises a fixing bracket, an ultrasonic transmitting probe and an ultrasonic receiving probe. The fixing bracket is installed on the initial portion of a drain pipe, and the ultrasonic transmitting probe is installed on the fixing bracket and can transmit a monitoring signal. The ultrasonic receiving probe is installed on the fixing bracket, the ultrasonic transmitting probe and the ultrasonic receiving probe are oppositely arranged, and the monitoring signal penetrates through a pipeline and a medium in the pipeline to be received by an ultrasonic probe. The refrigerator drain pipe freezing and blocking monitoring system can judge whether the drain pipe of a refrigerator is frozen and blocked or not and give out an alarm in time afterthe drain pipe is frozen and blocked. Meanwhile, the monitoring system can cooperate with a heating device to melt ice, ice melting is stopped in time after ice melting of the drain pipe is completed,and complex procedures and high fees caused by manual refrigerator disassembling for ice melting can be avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a monitoring system for freezing and blockage of drain pipes of refrigerators. Background technique [0002] In the evaporator system of the refrigerator, condensed water is usually produced, and the condensed water falls into the water collection pan of the evaporator under the action of gravity, and flows out through the drain pipe. As the temperature of the refrigeration working chamber of the refrigerator is usually low, the drain pipe and the water collecting pan are prone to freezing. After the drain pipe and the water collecting pan are frozen, the condensed water cannot be discharged, which will cause water accumulation in the working chamber of the refrigerator, affecting operation of the equipment. However, at present, the vast majority of electric heat tracing uses timing heating to melt ice. This ice melting method cannot respond in time according to ...

Problems solved by technology

As the temperature of the refrigeration working chamber of the refrigerator is usually low, the drain pipe and the water collecting pan are prone to freezing. After the drain pipe and the water collecting pan are frozen, the condensed water cannot be discharged, which will cause water accumulation in the working chamber of the refrigerator, affecting equipment operation

However, at present, the vast majority of electric heat tracing uses timing heating to melt ice. This ice melting method cannot respond in time according to the freezing situation in the drain pipe and water collection tray, and cannot monitor whether the drain pipe is blocked by ice. , After the drain pipe is blocked, it will affect the operation of the equipment. At present, it is necessary to manually disassemble the equipment, manually deicing, and unblocking; it consumes a lot of manpower and is expensive
