Description

Technical Field

[0001] This utility model relates to the field of stoves, and in particular to an electric flame and electric ceramic combination stove with an external circulation ventilation structure. Background Technology

[0002] An electric flame stove is a new type of kitchen stove that uses electricity to generate flames for heating instead of traditional gas. It breaks away from the traditional stove model that relies on gas fuel. Through plasma technology or the principle of electric arc discharge, it converts electrical energy into flames to provide a heat source for cooking. It is environmentally friendly, safe, and convenient. Compared to traditional gas stoves that use an integrated burner for flame heating, electric flame stoves rely on multiple electric arc devices to form separate burners for flame heating. When working, electric flame stoves accumulate a lot of heat inside. However, because the stove shell is embedded in the stove platform with the panel as the reference surface, and the stove shell is equipped with a gas supply fan that continuously draws in gas for plasma reaction, the heat can only flow in the nearly enclosed space inside, resulting in poor heat dissipation efficiency and hindering the reliable operation of the working components. Utility Model Content

[0003] The purpose of this invention is to provide an electric flame and electric ceramic combination stove with an external circulation ventilation structure. This invention achieves efficient heat dissipation and cooling by setting protrusions on the panel to connect the inner cavity of the stove shell with the outside, and by using a flow guiding device for active external circulation ventilation, thus improving the reliability of use.

[0004] The technical solution of this utility model is as follows: an electric flame and electric ceramic combination stove with an external circulation ventilation structure, including a stove shell, an electric flame stove assembly and an electric ceramic stove assembly in the inner cavity of the stove shell, a panel on the top of the stove shell, a protrusion on the top of the stove shell that is higher than the panel, an air inlet and an air outlet communicating with the inner cavity of the stove shell; and a flow guiding device is provided inside the stove shell to guide the gas from its inner cavity to the air outlet side.

[0005] In the above-mentioned electric flame and electric ceramic combination stove with an external circulation ventilation structure, the protrusion has a gas guiding cavity, and the outer side of the protrusion is provided with a lateral opening communicating with the gas guiding cavity; the air inlet and air outlet are located inside the gas guiding cavity.

[0006] In the aforementioned electric flame and ceramic combination stove with an external circulation ventilation structure, a grille is provided on the side opening.

[0007] In the aforementioned electric flame and ceramic combination stove with an external circulation ventilation structure, a partition plate is provided in the air guiding cavity between the air inlet and the air outlet.

[0008] In the aforementioned electric flame and ceramic combination stove with an external circulation ventilation structure, the air guiding cavity is a gradually narrowing cavity that is larger on the outside and smaller on the inside.

[0009] In the aforementioned electric flame and electric ceramic combination stove with an external circulation ventilation structure, the top surface of the stove shell is provided with an installation port, and the side of the installation port is connected to the air outlet; the flow guiding device is provided on the installation port.

[0010] In the aforementioned electric flame and electric ceramic combination stove with an external circulation ventilation structure, the corners of the air inlet and air outlet are rounded.

[0011] Compared with the prior art, the protrusion of this utility model protrudes from the panel after installation, allowing the inner cavity of the stove shell to communicate with the outside through the air inlet and outlet. During use, the flow guiding device is activated, which actively guides the heat generated by the electric flame stove assembly and the electric ceramic stove assembly from the inner cavity of the stove shell to the outside through the air outlet, achieving timely heat dissipation. At the same time, due to the negative pressure generated by the internal gas discharge, the cooler gas outside the stove is drawn into the inner cavity of the stove shell through the air inlet, achieving rapid cooling. This utility model effectively reduces the temperature of the inner cavity of the stove shell through external circulation, which is conducive to the reliable operation of the working parts.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example: An electric flame and electric ceramic combination stove with an external circulation ventilation structure, as shown in the attached figure. Figure 1As shown, the stove includes a cooker shell 1, within which an electric flame stove assembly 2 and an electric ceramic stove assembly 3 are installed. The electric flame stove assembly includes components such as an ion needle, an electric arc jet device, a ceramic compressor, a cathode tube, and a gas supply fan, generating a high-temperature flame through plasma reaction and electric arc discharge principles. The electric ceramic stove assembly includes a heating element and a reflector, heating through resistance heating principles. The electric flame stove assembly and the electric ceramic stove assembly work together to meet various cooking needs. These are all technologies well-known and mastered by those skilled in the art, and will not be described in detail here. A panel 4 is fixed to the top of the cooker shell 1. The panel is a microcrystalline glass panel to meet heat conduction requirements; as shown in the attached diagram. Figure 2 - Appendix Figure 5 As shown, the top of the stove shell 1 is integrally formed with a protrusion 5 that is higher than the panel 4. The protrusion 5 has an air inlet 6 and an air outlet 7 that communicate with the inner cavity of the stove shell 1. The stove shell 1 is equipped with a flow guiding device 8 that directs gas from its inner cavity to the air outlet 7. The flow guiding device can be a fan, nozzle, or compressor, etc. (See attached image) Figure 4 As shown, the protrusion 5 has an air-guiding cavity 9, and the outer side of the protrusion 4 has a lateral opening 10 communicating with the air-guiding cavity 9; the air inlet 6 and the air outlet 7 are located inside the air-guiding cavity 9, guiding airflow through the air-guiding cavity to avoid airflow turbulence affecting the air intake and exhaust effect. The protrusion is located on the side away from where the user stands, and the lateral opening faces away from the side where the user stands. The lateral opening guides airflow to prevent high-temperature gas from blowing towards the user, and external debris is not easily allowed to fall in; a grille 11 is machined on the lateral opening 10 to further prevent debris from entering; the air-guiding cavity 9 has a grille located at the air inlet 6 and the air outlet 7. The partition plate 12 between the inlets 7 prevents low-temperature gas from contacting high-temperature gas, ensuring the cooling effect; the air guiding cavity 9 is a tapered cavity with a larger outer surface and a smaller inner surface, which can guide the gas and increase the gas flow rate; the top surface of the stove shell 1 has an installation port 13, and the side of the installation port 13 is connected to the air outlet 7; the flow guiding device 8 is set at the bottom of the installation port 13, and the installation port is used to provide the installation position of the flow guiding device. Since the top of the installation port is covered by the panel, the flow guiding device below can guide the gas to the air outlet; the corners of the air inlet 6 and the air outlet 7 are rounded to guide the passing airflow.

[0020] Working principle: The protrusion 5 is higher than the panel 4. Its internal air-guiding cavity 9 connects the inner cavity of the stove shell 1 with the external space through the air inlet 6 and the air outlet 7. When the air guiding device 8 (such as a fan) is activated, it actively guides the hot air in the inner cavity of the stove shell 1 to the air outlet 7 through the installation port 13. At this time, the air pressure in the inner cavity decreases, forming a negative pressure. External cold air is drawn in from the air inlet 6 and enters the inner cavity of the stove shell 1 through the air-guiding cavity 9. When the cold air flows in the cavity, it absorbs the heat generated by the electric flame stove assembly 2 and the electric ceramic stove assembly 3, forming a heat exchange. The partition plate 12 in the air-guiding cavity 9 prevents the mixing of the inlet and outlet airflows. The gradually narrowing cavity structure The structure can accelerate gas flow and improve heat dissipation efficiency; the rounded transition design of the air outlet 7 and the air inlet 6 reduces airflow resistance and ensures smooth circulation; in this way, external cold air is continuously drawn in through the air inlet 6, heated and discharged through the air outlet 7, and the heat in the internal cavity is continuously removed through the external circulation mechanism, so that the temperature inside the stove shell 1 is maintained within a reasonable range, avoiding damage to the electric arc device of the electric flame stove component 2, the gas supply fan and the heating element of the electric ceramic stove component 3 due to high temperature, and ensuring long-term reliable operation of the equipment; in this process, the flow guiding device 8 actively drives the airflow, and the protrusion 5 and the air guiding cavity 9 form a circulation channel to achieve efficient heat dissipation and cooling.

Furthermore, in these embodiments, "up," "down," "left," "right," "front," and "back" represent relative positions only, not absolute positions.
