Abstract
Description
Technical Field
[0001] This utility model relates to the field of de-icing devices, and in particular to a rapid de-icing device. Background Technology
[0002] An ice maker is a refrigeration machine that uses a refrigeration system to cool water through an evaporator to produce ice. It employs a refrigeration system with water as the carrier, and produces ice by passing the water through a device when powered on. The shape of the ice produced varies depending on the evaporator's principle and the production method.
[0003] Regarding the aforementioned technologies, the existing de-icing devices have the following drawbacks: the de-icing solenoid valve is placed at the compressor exhaust port, resulting in low heat utilization. When the ambient temperature is low, the de-icing time is too long. At a certain low temperature, there is no temperature rise process, the space for refrigerant hot vapor to accumulate is small, and the energy provided for de-icing is too small, making de-icing impossible. Therefore, this utility model provides a rapid de-icing device. Utility Model Content
[0004] The purpose of this application is to provide a rapid de-icing device to solve the problems mentioned in the background art, such as the placement of the de-icing solenoid valve at the compressor exhaust port, which results in low heat utilization, excessively long de-icing time at low ambient temperatures, and failure to de-ic at certain low temperatures.
[0005] To achieve the above objectives, this application provides the following technical solution: a rapid de-icing device, comprising a compressor and a condenser, wherein the output end of the compressor is fixedly connected to a high-pressure exhaust pipe, the end of the high-pressure exhaust pipe away from the compressor is fixedly connected to a condenser inlet pipe, the condenser inlet pipe is connected to the input end of the condenser, the output end of the condenser is fixedly connected to a drying filter via a pipe, a de-icing solenoid valve is fixedly connected to the outside of the pipe, the output end of the de-icing solenoid valve is fixedly connected to a de-icing copper pipe, and the end of the de-icing copper pipe away from the de-icing solenoid valve is fixedly connected to an ice-making evaporator.
[0006] Preferably, a capillary tube is fixedly connected to the output end of the dryer filter, one end of the capillary tube is connected to the input end of the ice evaporator, a low-pressure return gas pipe is fixedly connected to the output end of the ice evaporator, and the end of the low-pressure return gas pipe away from the ice evaporator is connected to the input end of the compressor.
[0007] In summary, the technical effects and advantages of this utility model are as follows:
[0008] In this invention, by placing the de-icing solenoid valve between the condenser and the dryer filter, the fan is stopped before de-icing, causing a large amount of refrigerant to accumulate in the condenser and the temperature to rise sharply. When the de-icing solenoid valve is activated, a large amount of stored heat vapor in the condenser flows to the ice-making evaporator, thereby achieving a rapid de-icing process in a low-temperature environment.

[0015] Example: Reference Figure 1-2The rapid de-icing device shown includes a compressor 9 and a condenser 5. The compressor 9 compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas. Its output end is fixedly connected to a high-pressure exhaust pipe 1, which transports the high-temperature, high-pressure refrigerant gas compressed by the compressor 9. The end of the high-pressure exhaust pipe 1 furthest from the compressor 9 is fixedly connected to a condenser inlet pipe 2, which is connected to the input end of the condenser 5. The condenser 5 cools the high-temperature, high-pressure refrigerant gas into a high-temperature, high-pressure liquid, releasing heat in the process. A dryer filter 6 is fixedly connected to the output end of the condenser 5 via a pipe. The dryer filter 6 filters impurities and moisture from the refrigerant, preventing impurities from clogging the pipes and preventing moisture from freezing at low temperatures and affecting the device's operation. An ice-removing solenoid valve 3 is fixedly connected to the outside of the pipeline. The ice-removing solenoid valve 3 is used to control the flow direction of the refrigerant. When ice removal is required, it opens to allow some refrigerant to flow into the ice-removing copper pipe 4 for ice removal. The output end of the ice-removing solenoid valve 3 is fixedly connected to the ice-removing copper pipe 4. The end of the ice-removing copper pipe 4 away from the ice-removing solenoid valve 3 is fixedly connected to the ice-making evaporator 7. The ice-removing copper pipe 4 can transfer the heat of the high-temperature refrigerant to the ice-making evaporator 7, causing the ice on the surface of the ice-making evaporator 7 to melt, thus achieving rapid ice removal. The output end of the dryer filter 6 is fixedly connected to the capillary tube 10. The capillary tube 10 plays the role of throttling and pressure reduction, throttling the high-temperature and high-pressure refrigerant liquid into a low-temperature and low-pressure gas-liquid mixture. One end of the capillary tube 10 is connected to the input end of the ice-making evaporator 7. The ice-making evaporator 7 is the core component for ice making. The low-temperature and low-pressure refrigerant evaporates and absorbs heat in it, thereby lowering the ambient temperature and achieving ice making. The output end of the ice evaporator 7 is fixedly connected to a low-pressure return gas pipe 8. The end of the low-pressure return gas pipe 8 away from the ice evaporator 7 is connected to the input end of the compressor 9. The low-pressure return gas pipe 8 is used to transport the low-temperature, low-pressure refrigerant gas after evaporation by the ice evaporator 7 back to the compressor 9 to complete a refrigeration cycle.
[0016] The working principle of this practical system is as follows: Refrigerant flow during the ice-making process: The refrigerant is pressurized by the compressor 9 and discharged as hot vapor from the high-pressure exhaust pipe 1 of the compressor to the condenser 5. It flows in the condenser 5 and dissipates heat to the outside, gradually changing into a liquid phase. After the phase change, the refrigerant flows to the dryer filter 6. At this time, the de-icing solenoid valve 3 is in the closed state. It then flows from the dryer filter 6 to the capillary tube 10 to the inlet of the ice-making evaporator 7. After evaporating and making ice in the ice-making evaporator 7, it flows from the outlet of the ice-making evaporator 7 to the low-pressure return pipe 8, and finally returns to the compressor 9 to complete the ice-making cycle. Refrigerant flow during de-icing: The refrigerant is pressurized by compressor 9 and discharged to compressor high-pressure exhaust pipe 1. The hot vapor from compressor high-pressure exhaust pipe 1 flows to condenser 5. When de-icing occurs, the fan of condenser 5 stops in advance. Because the fan stops in advance, the refrigerant cannot dissipate heat to the outside, so no phase change process occurs. The refrigerant continues to be pressurized, and the temperature rises sharply (the shutdown timing corresponds to the ambient temperature, and our company has designed a time logic). After the set shutdown time is reached, the de-icing solenoid valve 3 opens. At this time, a large amount of high-temperature hot vapor after heating flows through the de-icing copper pipe 4 to the ice-making evaporator 7, where the ice melts. After the position change of the de-icing solenoid valve 3 and the change in the fan shutdown time logic, the fan is stopped before de-icing, causing a large amount of refrigerant to accumulate in condenser 5. At the same time, the temperature rises sharply. When the de-icing solenoid valve 3 is activated for de-icing, a large amount of stored hot vapor in condenser 5 flows to ice-making evaporator 7, thus realizing the rapid de-icing process in low-temperature environments.
[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
