Preferably, a storage temperature sensor is provided in the hot water chamber, and a temperature display connected to the storage temperature sensor is provided in the cabinet.

Preferably, the thickness of the thermal insulation layer is 50 mm, the material of the heating chamber is stainless steel, and the wall thickness of the heating chamber is 1.5 mm.

Preferably, a bathing room is provided in the motorhome, and the solar heat collector communicates with the bathing room.

The water in the cold water tank in the car is heated to 60°C to 90°C through the roof solar water heater, and then the hot water is stored in the sealed water tank in the heat preservation and hot vegetable cabinet. There is an insulation cavity for storing dishes on the upper part of the water tank. Made of food-grade stainless steel, the water temperature is transferred to the food in the cavity through the cavity wall to achieve heat preservation and heating functions. The water pressure of the heating pipeline system is provided by the pressure water pump inside the cabinet, and the power supply of the cabinet is powered by the vehicle 220V power supply.

Advantages: It provides a vehicle-mounted solar heating vegetable cabinet, which can heat food in the car without consuming a lot of electricity (the heat preservation function only needs the temperature display to work), and the pressure water pump is integrated inside the cabinet to provide water pressure for the shower room .

Specific implementation method: a solar heat collector is installed on the top of the caravan, and the solar heat collector is composed of multiple sets of vacuum solar heating tubes and reflection plates. There is a built-in cold water tank at the bottom of the RV. The cold water tank is equipped with a water level display and a water injection port, which is convenient for daily water filling. The water in the cold water tank is introduced into the solar collector for heating by the cold water pipe. to the valve. After the cold water is heated by the solar collector, it flows into the hot water chamber through the hot water pipe and is stored in the hot water chamber of the warming cabinet; a NTC storage temperature sensor is built in the hot water chamber, and the storage temperature sensor receives the temperature signal and transmits it to the temperature display; The shape of the sealing cover on the upper part of the water chamber sinks and is sealed and welded with the four walls of the hot water chamber to form a heating chamber; because the heating chamber is in contact with the hot water in the hot water chamber, the heat is transferred to the surface of the heating chamber through heat conduction, and the outside of the heating chamber is covered with Insulation layer, the insulation layer is made of polystyrene (PS) foam, and its thickness is 50mm; the upper part of the heating chamber is equipped with an insulation cover, the food to be heated is stored in the heating chamber, and the water temperature in the hot water chamber is transmitted through the heating chamber To the food stored in it, so as to play the role of heating and heat preservation. A water pressure pump is provided at the lower part of the warming cabinet to provide water pressure to the whole system to ensure the water pressure in the shower room.

Other instructions: The heating chamber and the hot water chamber are welded by SUS304 stainless steel, and the thickness is selected to be 1.5mm to ensure that the water tank is deformed due to the pressure change in the wall of the hot water chamber when the pressure water pump is working. The capacity of the hot water chamber is 45L because the cold water tank (60L) can ensure normal washing for 2 people after mixing hot and cold water. Even in the case of poor lighting conditions, the hot water capacity of the hot water chamber is 45L, which can ensure normal washing for one person. Metal hoses are used for the water inlet and outlet pipes of the thermal insulation warming cabinet, and the outer casing is covered with insulation pipes; as a preference, the solar collector can be equipped with an angle adjustment bracket to adjust the solar light receiving surface.

Therefore, a kind of vehicle solar energy multifunctional heat preservation warming dish cabinet of the utility model has high compactness, excellent heat preservation effect, and improves the comprehensive utilization rate of heat energy.
