Description

Technical Field

[0001] This utility model relates to the technical field of electric furnace protection devices, specifically a protective device for electric furnaces to prevent burns. Background Technology

[0002] Electric stoves, also known as electric heaters, are common heating devices. Their core working principle is that after the heating element is powered on, it generates heat and then the heat is directed to the heating area through a reflector to provide warmth. Their safety design is particularly important, especially the protective device, which needs to effectively prevent the human body from contacting the heating components in high-temperature environments.

[0003] Current electric furnace protective devices mostly use metal mesh (such as stainless steel or galvanized steel) as the protective mesh, combined with a surface anti-scalding coating to reduce surface temperature. However, under prolonged operation, the radiant heat from the heating element is continuously conducted to the protective mesh, causing its surface temperature to easily exceed the standard. Relying solely on the coating is insufficient for long-term stable temperature control. In such cases, people touching the protective mesh are easily burned, posing a certain safety hazard. Therefore, this utility model provides a protective device for electric furnaces to prevent burns. Utility Model Content

[0004] This utility model provides a protective device for electric furnaces to prevent burns. It has the advantage of active cooling function to prevent the surface temperature of the protective net from becoming too high, thus solving the problem that the surface temperature of the electric furnace protective net in the prior art is easy to exceed the standard during long-term use, and people are easily burned by contact with it.

[0005] To achieve the purpose of active cooling and preventing burns, this utility model provides the following technical solution: a protective device for electric stoves to prevent burns, applied to an electric stove, the electric stove including a shell, a reflector embedded inside the shell, and an electric heating element installed inside the reflector, including: The protective net is installed at the outer end of the shell and includes two mounting brackets. A liquid-passing bracket is fixed between the two ends of the two mounting brackets, and a protective pipe is connected between the two liquid-passing brackets. The heat dissipation component is installed inside the housing, and the liquid inlet is connected to the protective mesh through a liquid inlet pipe. The water tank is located below the protective net and is connected to the liquid outlet of the heat dissipation component via a liquid-conducting pipe. The liquid pump is located on one side of the water tank, with the inlet end connected to the water tank and the outlet end connected to the liquid guide frame on the upper side.

[0006] As a preferred technical solution of this utility model, the protective tube includes multiple vertically and inclined tubes, each tube is interconnected, and the outer ends of each tube are coated with an anti-scalding coating.

[0007] As a preferred embodiment of this utility model, the inside of the liquid-passing frame is hollow, and the interiors of the multiple tubes and the upper and lower liquid-passing frames are filled with coolant.

[0008] As a preferred embodiment of this utility model, the tube body is made of stainless steel, and the anti-scalding coating is formed by spraying silicone anti-scalding paint.

[0009] As a preferred embodiment of the present invention, the heat dissipation component includes a housing, a heat dissipation copper pipe is provided inside the housing, and openings are provided on both sides of the housing, with a fan installed at the outer end of one of the openings.

[0010] As a preferred technical solution of this utility model, the heat dissipation copper tube is in the form of multiple layers of bent stacks, and gaps are left between different columns of tubes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 This utility model discloses a protective device for electric stoves to prevent burns. The electric stove includes a shell 1, and a reflector 2 is embedded inside the shell 1. An electric heating tube 3 is installed inside the reflector 2. The electric stove adopts the mature working principle of electric stoves in the prior art, that is, after the power is turned on, the electric heating tube 3 heats up, and the reflector 2 reflects the heat forward for heating.

[0017] A protective net 4 is fixedly installed at the outer end of the outer shell 1. The protective net 4 includes two mounting brackets 41. A liquid-passing bracket 42 is fixed between the two ends of the two mounting brackets 41. A protective pipe 43 is connected between the two liquid-passing brackets 42.

[0018] Specifically, the protective tube 43 includes multiple vertically and inclined tubes 431, each tube 431 is interconnected, and the outer ends of each tube 431 are coated with an anti-scalding coating 432. The liquid-cooling frame 42 is hollow inside, and the multiple tubes 431 and the upper and lower liquid-cooling frames 42 are filled with coolant to form a liquid-cooling channel. The liquid flow absorbs the heat accumulated by the protective net 4 due to thermal radiation, thereby reducing the temperature of the tubes 431 and preventing the temperature of the protective tube 43 from becoming too high, thus playing an anti-scalding role.

[0019] The inclined tubes 431 are designed to reduce the gaps between them, improve physical blocking effect, and enhance safety. The inclined structure also facilitates coolant flow and prevents coolant stagnation. The mounting bracket 41 is not internally connected to the coolant guide bracket 42 and has holes on both its upper and lower sides for mounting and fixing to the outer casing 1 with screws.

[0020] In this embodiment, the tube body 431 is made of stainless steel. Stainless steel has the characteristics of high temperature resistance and high strength, which ensures the stability of the protective mesh structure. At the same time, it is not easy to react with the coolant and has a long service life. The anti-scalding coating 432 is sprayed with silicone anti-scalding paint, which has good heat insulation properties.

[0021] A heat dissipation component 6 is installed inside the outer casing 1. The liquid inlet of the heat dissipation component 6 is connected to the protective net 4 through a liquid inlet pipe 7. Specifically, the heat dissipation component 6 includes a housing 61, inside which a heat dissipation copper pipe 62 is provided. Openings are provided on both sides of the housing 61, and a fan 63 is installed at the outer end of one of the openings. The heated coolant flows into the heat dissipation component 6 through the liquid flow pipe 8 and is cooled by the heat dissipation copper pipe 62 and the fan 63.

[0022] The heat dissipation copper pipe 62 is stacked in multiple bends, with gaps between different pipes. The two ends of the heat dissipation copper pipe 62 extend out of the housing 61 as the liquid inlet and liquid outlet ports, respectively. The heat dissipation copper pipe 62 is stacked in a serpentine shape to increase the contact area with air, and the heat carried by the coolant is efficiently conducted to the air through the copper pipe wall.

[0023] It should be noted that a heat dissipation vent 5 is provided on the lower side of the rear end face of the outer casing 1, and the heat dissipation component 6 is installed inside the heat dissipation vent 5 with the fan 63 facing the opening of the heat dissipation vent 5. In addition, an air inlet (not shown in the figure) is provided on the lower side of the front end face of the outer casing 1 to ensure smooth airflow.

[0024] A water tank 9 is installed below the protective netting 4. The water tank 9 is connected to the outlet of the heat dissipation component 6 via a liquid pipe 8. A liquid pump 10 is installed on one side of the water tank 9, with its inlet connected to the water tank 9 and its outlet connected to the upper liquid flow rack 42 via a pipe 11. Specifically, the coolant in the water tank 9 is driven by the liquid pump 10 and pumped into the liquid cooling channel of the protective net 4 through the liquid pipe 7. It absorbs the heat of the protective net 4, and the liquid temperature rises. The heated coolant flows into the heat dissipation component 6 through the liquid pipe 8 to cool down. The cooled liquid returns to the water tank 9, forming a cycle, continuously reducing the temperature of the protective net 4, and can work continuously for a long time.

[0025] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
