Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a power supply according to the present invention.

A power supply comprising: the device comprises a power supply functional component, a heat insulation shell 2, a semiconductor refrigerating sheet 3, a heater 4 and a heat conduction shell 5.

The power functional component comprises a plug 11, a component 12 and an output wire 13 which are electrically connected in sequence. The plug 11 is made of a good electrical conductor and is used for being plugged into a power socket to be connected with an external power supply. The component 12 is a commonly used electrical component in a power plug, and is used for converting commercial power in a power grid into electric energy for the range hood. One end of the output wire 13 is connected with the component 12, and the other end is connected with other parts of the range hood for transmitting electric energy to the components.

Thermal-insulated shell 2 encloses with semiconductor refrigeration piece 3 and forms thermal-insulated chamber, and the intracavity that insulates against heat is placed in to components and parts 12, and thermal-insulated shell 2 is used for isolated heat that heater 4 produced, protection components and parts 12. Because the heat insulation shell 2 can not completely insulate heat, a small amount of heat generated by the heat insulation heater 4 still passes through the heat insulation shell 2 and enters the heat insulation cavity, so that the temperature in the heat insulation cavity is continuously increased. Therefore, the semiconductor refrigerating sheet 3 is arranged to continuously convey heat in the heat insulation cavity to the outside, and the temperature of the component 12 is prevented from being too high. Semiconductor refrigeration piece 3 and bolt 11 electric connection, when smoke ventilator began work, components and parts 12 just began work simultaneously. In order to better transfer heat and protect the component 12, the cold end of the semiconductor refrigeration piece 3 is attached to the component 3, and the hot end faces the outside.

The heat insulation shell 2 and the heat conduction shell 5 surround to form a heating cavity, and the heater 4 is arranged in the heating cavity and electrically connected with the plug pin 11. When the range hood starts to work, the heater 4 starts to work to generate heat, so that the temperature of the heat conduction shell 5 rises, and the oil smoke generated during cooking is difficult to adhere and condense on the heat conduction shell 5. When the cooking is finished, after the power plug is pulled off, the heat conducting shell 5 is wiped before the heat conducting shell 5 is not cooled, grease on the heat conducting shell can be easily wiped off, and accumulation of grease is avoided. The heater 4 may be a conventional heating wire structure.

Since the working environment temperature of the output electric wire 13 cannot be too high, the output electric wire 13 cannot pass through the heating chamber and needs to be arranged through the semiconductor chilling plate 3.

Implement the embodiment of the utility model provides a, following beneficial effect has: the utility model discloses a power utilizes the heater heating for outside heat conduction shell keeps a higher temperature when using, and the oil smoke is difficult to condense on power plug, cleans clean also can be easily after finishing using and wipe the grease on, separates the heat that the isolated heater of shell produced simultaneously, and the protection power supply functional component does not damage because of the high temperature.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
