Detailed Description
Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.
The electric oven shown in fig. 1 is a schematic structural view, and includes:
The oven comprises a box body 1, wherein an electric control box 2 and an oven liner 3 are arranged in the box body, and a plurality of cooling fans 4 are arranged in the electric control box 2;
the inner side of the thermoelectric generation sheet 5 is attached to the outer wall of the oven liner 3, and is electrically connected with the cooling fan 4 through a boosting module.
Specifically, as shown in fig. 1 and 2, the electric oven is composed of an oven body 1, an oven liner 3, an electric cabinet 2 and a thermoelectric generation sheet 5. Wherein, oven inner bag 3 and electric cabinet 2 all set up in box 1. The control main board of the electric oven is arranged in the electric cabinet 2, two cooling fans 4 are arranged in the electric cabinet 2, and the two cooling fans 4 are powered by thermoelectric generation sheets 5 arranged on the outer wall of the oven liner 3. The inner side surface of the thermoelectric generation sheet 5 is attached to the high-temperature oven liner 3, and the outer side surface is positioned in the oven body 1 with relatively low temperature, so that the heat emitted by the oven liner 3 can be absorbed by utilizing the principle of thermoelectric generation, and the absorbed heat is converted into electric energy. The boost module can convert the generated electric energy into direct current with corresponding voltage to be supplied to the cooling fan 4, so that the cooling fan 4 is driven to cool the control main board, and the aim of reducing energy consumption is achieved.
In this embodiment, optionally, an insulating layer 8 is disposed on an outer wall surface of the oven liner 3. The heat insulation layer 8 can prevent a large amount of heat in the oven liner 3 from radiating into the oven body 1. In this embodiment, the heat insulating layer 8 may be heat insulating cotton, which covers the area of the outer surface of the oven liner 3 except the area where the thermoelectric generation pieces 5 are located.
In this embodiment, optionally, a radiator 7 is further included, and the radiator 7 is located outside the thermoelectric generation sheet 5. The radiator 7 can accelerate the heat dissipation of the outer side surface of the thermoelectric generation sheet 5, so that the temperature difference is kept between the inner side surface and the outer side surface of the thermoelectric generation sheet 5 all the time in the working process of the electric oven, and the thermoelectric generation sheet 5 can continuously generate power to be supplied to the cooling fan 4.
In this embodiment, optionally, the oven further comprises a mounting plate 6, the mounting plate 6 is fixed on the outer wall of the oven liner 3, and the inner side of the thermoelectric generation sheet 5 is attached to the mounting plate 6.
Specifically, the thermoelectric generation sheet 5 has an outer side surface and an inner side surface, the outer side surface and the inner side surface are respectively a heat absorption surface and a heat dissipation surface, and the thickness is smaller, generally 4-5 mm. If the heat absorbing surface is directly attached to the outer wall of the oven liner 3, the heat insulating layer 8 wrapped by the outer wall of the oven liner 3 is thicker, generally 30-40 mm, and the periphery of the heat radiating fins attached to the heat radiating surface is shielded by the heat insulating layer 8, so that the heat radiating efficiency is reduced, and the temperature difference is reduced to influence the power generation.
In order to ensure good heat dissipation, the heat sink 7 needs to be completely exposed. Therefore, the mounting plate 6 is bonded and welded with the outer wall of the oven liner 3, and the heat of the oven liner 3 can be directly transferred to the mounting plate 6. The temperature difference piece 5 is attached to the mounting plate 6 to absorb heat.
In this embodiment, optionally, the thermoelectric generation sheet 5 is adhered to the mounting plate 6 by a heat-conducting adhesive. The heat conduction coefficient of the heat conduction glue is higher, and the heat transfer is facilitated, so that the thermoelectric generation sheets 5 can absorb enough heat to generate electricity.
In this embodiment, optionally, the heat sink 7 is attached to the thermoelectric generation sheet 5 by a heat-conducting adhesive. The heat conduction coefficient of the heat conduction glue is higher, and the heat transfer is facilitated, so that the heat radiator 7 can be ensured to rapidly radiate and remove the heat on the outer side face of the thermoelectric generation sheet 5.
The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description.
