Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic smoke stoves, and more particularly to an electromagnetic heating and heat dissipation structure of an electromagnetic smoke stove. Background Art

[0002] Electromagnetic range cookers operate by utilizing electromagnetic radiation to heat the cooker, making them popular with many families due to their ease of use and portability. However, during the heating process, heat from the cooker is directly transferred to the cooktop, raising its temperature. This heat then radiates into the cooktop, raising the temperature inside. Simultaneously, the cooktop's main control board and other electronic components generate heat during operation. Excessively high temperatures in the working area can affect the lifespan of these components and reduce the cooktop's energy efficiency. Currently, electromagnetic range cookers typically use fan convection for heat dissipation, but the heat dissipation duct is short and located within the cooktop, leaving room for improvement in heat dissipation efficiency. Some existing electromagnetic range cookers feature a rear exhaust and oil suction mechanism. Specifically, a partition wall is installed on one side of the cooktop, with a vent facing upward. A fan is installed within the vent, with the fan positioned at an angle of 30-50° to the partition wall. However, using these cooktops requires drilling a hole in the partition wall to install the fan, making them inconvenient. Moreover, there is a certain angle between the fan of the electromagnetic smoke and the wall of the partition. Since the fan is installed at a certain angle, the depth of the stove must be increased to meet the user's usage habits. Most stoves in modern kitchens are of a uniform depth, which limits the application of the stove and requires improvement. Utility Model Content

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The electromagnetic smoke cooker provided by the utility model includes a stove body 1 and a fume suction device 2. The stove body 1 includes a first shell, an electromagnetic heater 11, a main control board 13, a microcrystalline panel 12, a cooking operation area 18, and a first fan assembly 15 for dissipating heat inside the stove body; the fume suction device 2 includes a second shell, a second fan assembly 21, and an oil drain assembly 4; the electromagnetic smoke cooker also includes a connecting cavity for connecting the air outlet of the first fan assembly with the air inlet of the second fan assembly.

[0024] The oil fume extraction device is located at the upper rear of the first housing. Figure 1-2 As shown, the cooking area 18 of the first housing is the front of the oven body 1, and the side opposite the front is the rear of the oven body. The fume extraction device is installed perpendicular to the top panel of the oven body 1 and located at the upper rear of the oven body. At the rear of the oven body 1, a windshield 3 connects the back of the oven body 1 and the bottom of the fume extraction device 2, forming the communication cavity 31.

A first mounting opening for an oil drain assembly is provided on the front panel of the second housing. The oil drain assembly is removably mounted to the first mounting opening of the second housing by snap-on insertion or screw fastening, allowing it to be removed for cleaning and disposal of oil. A second mounting opening for accommodating or mounting an oil cup 32 is provided on the bottom panel of the second housing. The oil drain assembly filters cooking fumes, while oil is absorbed by the drain assembly and falls by gravity through the second mounting opening into the oil cup.

The air inlet 16 of the first fan assembly is located on the bottom plate of the furnace body 1, and the air outlet 17 of the first fan assembly is located on the back plate of the furnace body 1. The first air duct draws air upward from the bottom of the furnace body, passes through the heat dissipation fins 14 of the main control board 13, leaves the furnace body through the air outlet 17, and enters the connecting cavity 31. The second fan assembly 21 has a second air duct and a third air duct. The second air duct connects the connecting cavity 31 with the air outlet 23 of the second housing. Ambient air passes through the first air duct, carrying heat from the furnace body into the connecting cavity 31, thereby lowering the temperature inside the furnace body. A second air inlet 22 is provided on the bottom plate of the range hood 2, and the air outlet 23 of the second housing is provided at the top of the back plate of the range hood 2. A smoke pipe connecting ring 6 is also fixed to the air outlet 23 of the second housing. The second fan assembly 21 is a volute fan, which is mounted on the back panel of the second housing. Its air inlet faces the oil drain assembly 4 and is some distance away from the front panel of the second housing. The hot air flow in the connecting cavity 31 enters the bottom of the second housing cavity from the second air inlet 22, passes through the air outlet 23 of the second housing along the second air duct, and then leaves the electromagnetic smoke cooker from the air outlet 23 of the second housing and the smoke pipe connecting ring 6, forming an external exhaust system. The third air duct is used to discharge the oil smoke generated during the cooking process. The third air duct starts from the space in front of the oil drain assembly 4, passes through the air gap of the oil drain assembly 4, the air inlet of the volute fan, the internal air duct of the volute, and reaches the smoke pipe connecting ring 6. The cooking pots placed on the microcrystalline panel 12 generate oil smoke during operation, which is filtered by the oil drain assembly 4 and then extracted from the electromagnetic smoke cooker by the volute fan. The oil drain assembly includes two oil filter screens 41 and an oil filter element 42, which is sandwiched between the two oil filter screens. The oil filter element is composed of several oil filter wires. The oil drain assembly is installed in a detachable manner, greatly facilitating the user to remove and clean the oil drain assembly or replace the oil filter element.

[0027] The first air duct frame structure consists of side frames, a middle partition 8, and an upper cover 9. The middle partition 8 divides the heat dissipation working area enclosed by the side frames into two left and right sections. Axial fans (151, 152) are provided on the air inlet side of each of the left and right sections. Heat dissipation fins 14 are used to enhance the heat dissipation effect of the main control board 13 and are arranged in one section. The other section is where the high-power components on the main control board are located. In order to improve the heat dissipation effect of the heat dissipation fin section and prevent air from flowing between the two sections, an upper cover 9 is provided on top of the heat dissipation fin section to separate it from the other section.

[0028] Working process of electromagnetic smoke cooker: turn on the switch, the first and second fan assemblies work, the heat of the stove body is dissipated through the first and second air ducts, the oil smoke generated by cooking passes through the third air duct, and the oil smoke air inlet uses the volute fan to suck away the oil smoke during the cooking process into the second shell cover, the oil smoke is filtered by the oil drain, the oil smoke gas and liquid are separated, the liquid oil flows into the oil cup, and the oil smoke-free air is discharged from the smoke pipe connecting ring sleeve 6.
