Description

Technical Field

[0001] This invention belongs to the technical field of vehicle-mounted refrigerator ice-making equipment, specifically relating to an ice-making device and a vehicle-mounted refrigerator based on the principle of a shared compressor. Background Technology

[0002] As living standards continue to improve, cars are no longer just a means of transportation, but are gradually becoming an extension of mobile living spaces, and people have higher and higher requirements for the driving experience. Most existing car refrigerators only have a cooling function. In the high temperatures of summer, users often need iced drinks and chilled food when traveling, but existing car refrigerators can only keep existing ice warm and cannot make ice in real time. In scenarios where there is a lack of external ice-making conditions, such as outdoor camping and long-distance off-roading, users cannot obtain fresh ice, which not only affects the drinking experience of beverages, but also makes it difficult to effectively preserve food that requires deep refrigeration, thus affecting the user experience.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a vehicle refrigerator with a water-flow ice-making structure [202321484474.9], which includes a vehicle refrigerator body, a storage cavity, an ice storage cavity, an ice tray set in the ice storage cavity, a water return port at the bottom of the ice storage cavity, a spray pipe, a water pump connected to the water return port and the spray pipe, an ice-making evaporator, a refrigeration evaporator, a condenser, and a compressor. By independently setting up an ice storage cavity, when ice is needed, water is poured into the ice storage cavity, and the ice-making evaporator is started. The water flows into the water pump along the water return port and is pumped into the spray pipe. Then, it flows along the spray pipe into the water spraying area at the top of the ice tray, and then flows along the water spraying area into the ice-making grid at the front of the ice tray. The ice-making evaporator absorbs heat from the water in the ice-making grid, so that the temperature of the water gradually decreases during the continuous flow, and finally it is frozen into ice in the ice-making grid.

[0004] The above solution has solved the problem of existing car refrigerators not being able to make ice to some extent, but the solution still has many shortcomings. For example, its built-in compressor makes the cost of the car refrigerator high and increases the space occupied by the car refrigerator, affecting the user's riding space. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing an ice-making device based on the principle of a shared compressor.

[0006] Another objective of this invention is to provide a vehicle-mounted refrigerator to address the aforementioned problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An ice-making device based on the principle of a shared compressor includes an ice box base with an ice box body. The ice box base is located on the outside of a vehicle refrigerator. An ice-making module connected to an air conditioning refrigeration system is provided on one side of the ice box base. An ice-making mechanism connected to the ice box body is provided on the ice-making module.

The ice box base facilitates the placement of the ice box body, and its location on the outside of the vehicle refrigerator allows users to retrieve ice without opening the vehicle refrigerator, reducing the loss of cold air inside the vehicle refrigerator. The air conditioning refrigeration system provides refrigerant, which enables the ice-making mechanism to make ice through the ice-making module. The air conditioning refrigeration system ensures the ice-making effect, reduces the overall space occupied by the vehicle refrigerator, improves the user's driving experience, and reduces the cost of the ice-making equipment.

[0008] In the aforementioned ice-making device based on the principle of a shared compressor, the air conditioning refrigeration system includes an air conditioning evaporator. One side of the air conditioning evaporator is connected to the air conditioning compressor via a pressure regulating valve. A four-way valve is provided between the pressure regulating valve and the air conditioning compressor. The other side of the air conditioning compressor is equipped with a condenser and a dryer filter. The dryer filter is connected to the other side of the air conditioning evaporator via an air conditioning expansion valve. A first three-way valve is provided between the dryer filter and the air conditioning expansion valve. The dryer filter can purify the refrigerant and absorb moisture. The purified refrigerant flows through the first three-way valve to the air conditioning expansion valve and the ice-making module, respectively.

The refrigerant then flows through the second three-way valve to the ice-making liquid-cooled plate evaporator, where it exchanges heat with the ice-making mechanism to produce ice. After heat exchange, the refrigerant returns to the air conditioner compressor via the first one-way valve and the four-way valve. In heating mode, the first solenoid valve closes, and the ice-retrieving heating film heats the ice, allowing for quick ice retrieval, improving efficiency and enhancing the user experience.

[0014] In the aforementioned vehicle refrigerator, the rear cover assembly includes a rear cover body, a rear cover cavity within the rear cover body, a rear cover insulation layer within the rear cover cavity, and a cold storage mechanism disposed within the rear cover insulation layer. The cold storage mechanism includes a cold storage box containing cold storage liquid, which is disposed within the rear cover insulation layer.

The refrigerator cavity forms an internal circulation channel with the rear cover cavity through the air inlet / outlet grille and the heat exchange holes. A finned liquid cooling plate is disposed within the internal circulation channel. An internal circulation fan is located above the heat exchange holes. The internal circulation fan is connected to the refrigerator evaporator via an evaporator bracket on the side facing the rear cover cavity. The refrigerator evaporator is connected to the second three-way valve via a second solenoid valve on one side, and to the four-way valve via a second one-way valve on the other side. A heating film heats the refrigerator cavity, improving the user experience. The insulation layer of the cabinet maintains the temperature inside the refrigerator cavity. A refrigeration installation notch facilitates the placement of the air duct housing, and heat exchange holes within the air duct housing allow for the installation of the internal circulation fan. The internal circulation fan and internal circulation channel improve the heat exchange efficiency of the air inside the refrigerator cavity. A finned liquid cooling plate provides initial cooling of the air in the internal circulation channel. Even in the event of a power outage, continuous heat exchange and cooling are maintained inside the refrigerator cavity. In cooling mode, the second solenoid valve is activated, allowing refrigerant from the refrigerator expansion valve to flow through the second solenoid valve to the refrigerator evaporator for heat exchange. The internal circulation fan exchanges heat between the air in the internal circulation duct and the refrigerator evaporator, ensuring the cooling effect inside the refrigerator cavity.

[0016] In the aforementioned vehicle refrigerator, the cover assembly includes a decorative frame disposed on the upper end of the inner shell and outer shell of the refrigerator.
