Description

Technical Field

[0001] This invention belongs to the field of handle technology, specifically relating to a fully automatic hot water refrigeration ice maker and its temperature control ice-making method. Background Technology

[0002] As living standards improve, consumers' demands for drinking water are becoming more diversified. Room temperature water, ice water, and ice cubes are increasingly used in daily drinking, tea preparation, and beverage making. Currently, drinking water and ice-making equipment on the market have limited functionality and cannot integrate boiling, cooling, ice making, and ice removal, exhibiting significant technological shortcomings.

[0003] Most existing ice makers are standalone devices, requiring an external water source and unable to directly prepare boiling water. Ordinary water dispensers only provide hot water and lack cooling and ice-making capabilities. While some integrated devices offer basic drinking water functionality, they are slow at making ice and often use room-temperature water directly, which is not boiled or sterilized, making the ice prone to bacterial growth and posing a safety risk. Furthermore, these devices have low automation; boiling, filling, ice-making, and ice-removing all require manual operation, resulting in a cumbersome and inefficient process.

[0004] Furthermore, traditional ice-making methods result in ice melting that easily dilutes beverages and ruins their taste; manual ice removal easily leads to ice breakage, high loss rates, and the risk of frostbite. In summary, existing technologies cannot integrate the entire process of boiling water, cooling, ice making, and ice removal, resulting in drawbacks such as slow ice-making speed, poor water quality safety, low automation, ice easily diluting beverages, and inconvenient ice removal. These shortcomings make it difficult to meet users' needs for efficient, safe, and convenient access to various forms of drinking water. Therefore, a fully automatic water boiling, cooling, and ice-making equipment is urgently needed to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic boiling water refrigeration ice maker and its temperature-controlled ice-making method, which solves the technical defects of existing technologies such as slow ice-making speed, poor taste, low degree of automation, and inability to integrate boiling water, refrigeration, ice making, and ice removal.

[0006] The technical solution provided by this invention: A fully automatic hot water refrigeration ice maker, comprising a body, wherein the body is provided with a kettle assembly and a cup holder for placing cups; the cup holder is provided with a water outlet and an evaporator, the water outlet being connected to the water outlet end of the kettle assembly;

[0007] The machine body integrates a refrigeration and heating cycle system, which includes a compressor, a three-way solenoid valve, a condenser, and a throttle valve. The compressor refrigerant interface is connected to the three-way solenoid valve, which is connected to the condenser and the evaporator respectively. The condenser is connected to the throttle valve and the evaporator in sequence, and the evaporator is connected back to the three-way solenoid valve to form a complete closed-loop refrigerant circulation circuit.

[0008] A temperature-controlled ice-making method for a fully automatic hot water refrigeration ice maker includes a boiling water injection stage, a rapid cooling and freezing stage, and a heat pump automatic heating and de-icing stage.

[0009] S1. Boiling water and automatic water filling: After the equipment is started, the kettle component heats the water to 100℃ boiling point. After the user places an empty cup, the equipment automatically fills the cup with boiling water through the outlet, completing the automatic water filling.

[0010] S2. Rapid Cooling and Freezing: After water filling, the main control board switches the three-way solenoid valve to cooling mode, the compressor starts, and the high-temperature, high-pressure refrigerant is cooled by the condenser and depressurized by the expansion valve, becoming a low-temperature, low-pressure liquid refrigerant that enters the evaporator. The evaporator rapidly cools down and is immersed in the boiling water in the cup, quickly absorbing heat from the water, causing the boiling water to cool down rapidly and freeze. The temperature sensor collects the temperature in real time, and the cooling process stops when the preset low temperature or freezing threshold is reached. This step allows for temperature adjustment as needed to prepare various forms of water, such as room temperature water, ice water, and solid ice.

[0011] S3, Automatic De-icing in Heat Pump Heating: After freezing, the main control board switches the three-way solenoid valve to switch the equipment to heat pump heating mode. High-temperature and high-pressure refrigerant is directly introduced into the evaporator, causing the evaporator surface to heat up rapidly, melting the adhered ice layer locally, creating a separation gap between the ice and the evaporator, eliminating the adhesion effect. After de-icing, the cup can be directly removed.

[0012] The present invention has the following advantages: the device integrates a kettle component, a refrigeration and heating circulation system and an automatic control module, which can complete the entire process of boiling water, automatic water filling, rapid cooling, ice making and heat pump de-icing without manual intervention, with a high degree of automation and convenient use; there is no need for external ice adding, which completely avoids the problem of ice cubes diluting tea drinks and ruining the taste.

[0019] like Figures 1 to 5 As shown, a fully automatic hot water refrigeration ice maker includes a body 10. The body 10 is provided with a kettle assembly 20 and a horizontally arranged cup holder 30, which is used to place cups 11. The cup holder 30 is provided with a water outlet 12 and an evaporator 13, and the water outlet 12 is connected to the water outlet end of the kettle assembly 20.

[0020] The unit 10 integrates a refrigeration and heating cycle system 40, which includes a compressor 41, a three-way solenoid valve 42, a condenser 43, and a throttle valve 44. The compressor 41 has a refrigerant interface connected to the three-way solenoid valve 42, which is connected to the condenser 43 and the evaporator 13 respectively. The condenser 43 is connected to the throttle valve 44 and the evaporator 13 in sequence, and the evaporator 13 is connected back to the three-way solenoid valve 42, forming a complete closed-loop refrigerant circulation circuit.

[0021] The cup holder 30 is provided with a cup positioning groove 31, so that the cup 11 rises to the evaporator 13 after being placed, and the evaporator 13 realizes heat exchange inside the cup 11; the body 10 is provided with a temperature control detection component, including a temperature sensor located in the evaporator 13. The temperature sensor, compressor 41, and three-way solenoid valve 42 are all electrically connected to the main control board to realize automatic mode switching and precise temperature control.

[0022] The equipment can switch between cooling mode and heat pump de-icing and heating mode via a three-way solenoid valve 42; the compressor 41 provides refrigerant circulation power, the condenser 43 realizes refrigerant heat dissipation, the throttling valve 44 realizes throttling and pressure reduction, and the evaporator 13 realizes water heat absorption and cooling and its own heating and de-icing.

[0023] The present invention realizes a fully automatic three-stage working process, including a boiling water injection stage, a rapid cooling and freezing stage, and a heat pump automatic heating and de-icing stage.

[0024] S1. Boiling water and automatic water filling: After the equipment is started, the kettle component 20 heats the water to 100℃ boiling point. After the user places an empty cup 11, the equipment automatically fills the cup 11 with boiling water through the outlet, thus completing the automatic water filling.

[0025] S2. Rapid Cooling and Freezing: After water filling, the main control board switches the three-way solenoid valve 42 to cooling mode, and the compressor 41 starts. The high-temperature, high-pressure refrigerant is cooled by the condenser 43 and depressurized by the expansion valve 44, becoming a low-temperature, low-pressure liquid refrigerant that enters the evaporator 13. The evaporator 13 rapidly cools down and is immersed in the boiling water in the cup, quickly absorbing the heat from the water, causing the 100℃ boiling water to cool down rapidly and freeze. The temperature sensor collects the temperature in real time, and the cooling process stops when the preset low temperature or freezing threshold is reached. This step allows for temperature adjustment as needed to prepare various forms of water, such as room temperature water, ice water, and solid ice.

[0026] S3, Automatic De-icing in Heat Pump Heating: After freezing, the main control board switches the three-way solenoid valve 42 to switch the equipment to heat pump heating mode. High-temperature and high-pressure refrigerant is directly introduced into the evaporator 13, which rapidly heats the surface of the evaporator 13, locally melting the adhered ice layer and creating a separation gap between the ice and the evaporator 13, eliminating the adhesion effect. After de-icing, the cup body 11 can be directly removed.

[0027] In summary, this invention automates the entire process of boiling water, adding water, cooling, making ice, and removing ice, requiring no manual intervention or external ice addition, thus completely eliminating the problem of ice diluting tea drinks and ruining their taste.
