Description

Technical Field

[0001] This utility model relates to the field of refrigeration and heating technology, specifically a portable integrated refrigeration and heating machine. Background Technology

[0002] Integrated cooling and heating units can simultaneously perform both cooling and heating functions. They are highly integrated, easy to install and arrange, and simultaneously meet the needs of both heat preservation / heating and cold preservation / cooling. Portable integrated cooling and heating units based on thermoelectric refrigeration have great development potential in the portable integrated cooling and heating unit field due to their ease of control, lack of chemical reactions, absence of moving parts, no use of working fluids, absence of pollutants that contribute to global warming, and high efficiency and reliability in cooling.

[0003] The constant temperature heating and cooling integrated machine disclosed in Chinese Utility Model Patent Application Publication No. CN212481822U allows the user to operate a suction fan. The suction force generated by the suction fan can lift the spherical piston in the mounting hole, thereby connecting the inner cavity three and inner cavity two. This allows a small amount of cold air to be extracted from inner cavity two, thus lowering the temperature in inner cavity three, which is convenient for use. However, existing heating and cooling integrated machines require an electrical cord to be connected to the device for power supply, making them unportable and inconvenient for outdoor use. After long-term use, Freon evaporates, resulting in a decrease in cooling effect and excessive noise during operation. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a portable integrated cooling and heating unit, comprising a main body, a cover snapped onto the upper surface of the main body, a copper pipe disposed inside the main body, a connecting fan installed inside the main body, a main heat dissipation fin mounted on the lower part of the connecting fan, a cooling plate mounted on the lower surface of the main heat dissipation fin, a secondary heat dissipation fin mounted on the lower surface of the cooling plate, a fixed fan inserted into the lower surface of the secondary heat dissipation fin, a movable plate mounted on the surface of the cooling plate, a battery snapped onto the lower surface of the main body, and a bottom shell fitted onto the lower surface of the main body.

[0006] Optionally, the cover is rotatably connected to a handle, and the number of handles is two.

[0007] Optionally, the main body is provided with a sealing ring inside, and the sealing ring is made of silicone rubber.

[0008] Optionally, the main body has multiple docking grooves inside, and the lower part of the cover has multiple limiting grooves.

[0009] Optionally, the lower part of the bottom shell is provided with multiple anti-slip pads, and the anti-slip pads are made of rubber.

[0010] Optionally, the surface of the bottom shell is provided with a plurality of heat dissipation holes, and the intervals between the heat dissipation holes are equal.

[0011] Optionally, the lower part of the main body is provided with a limiting seat, the lower part of the main body is installed with a mating interface, and a mating hole is opened on one side of the bottom shell.

[0012] Optionally, a hole is provided on one side of the main body, a handle is provided on one side of the movable plate, and a control panel is installed on one side of the main body.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. This utility model has a reasonable structure. By using the handle on the cover, the user can easily and quickly move the equipment, reducing the inconvenience of taking the equipment outdoors and the effort required to move it. By rotating the cover, the limiting groove of the cover rotates out of the docking groove inside the main body. After removing the cover from the main body, the contents are placed inside, and then the cover is placed back on the main body and secured. The sealing ring seals the inside of the equipment. By removing the bottom shell from the main body, the battery is installed on the main body and secured to the limiting seat. After the battery is depleted, it can be removed for charging. When used indoors, it can be charged with external electricity. The cable is inserted into the interface at the bottom of the main body to power the device. The cooling coils operate, and the main heat sink fins and connecting fan transfer heat to the copper pipes to adjust the internal temperature of the main body. The auxiliary heat sink fins and fixed fan also dissipate the heat from the cooling coils. When the internal temperature needs to be raised, the user removes the movable plate and cooling coils, flips them over, inserts them again, and then the cooling coils operate to raise the internal temperature. This achieves convenient and quick temperature adjustment, simple and flexible operation, more uniform overall temperature control, and more stable and rapid cooling or heating effects, improving overall efficiency and reducing the limitation of the device being restricted to indoor use, thus broadening its applicability.
