Description

Technical Field

[0001] This utility model relates to the field of stoves, and in particular to a cooling cover and a dual-purpose stove including the same. Background Technology

[0002] As a balancing machine, the dual-purpose furnace mainly relies on external air supply for air intake. When the machine is working, the combustion chamber will radiate a lot of heat, causing the internal temperature of the machine to rise significantly. Some dual-purpose furnaces have the electronic controller placed inside the cavity during the design process. Affected by the high temperature radiation, the temperature of some components may be too high, which will affect their lifespan.

[0003] Existing solutions mainly rely on adding heat insulation cotton inside the combustion chamber to reduce the radiant heat of combustion, thereby lowering the temperature inside the chamber. However, the overall temperature is still relatively high, which poses a significant challenge to the performance of components.

[0004] In addition, some machine masks use a low-temperature ink glass process, which has relatively high temperature requirements. Insulation cotton needs to be added to maintain a low temperature, which increases the cost. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing dual-purpose furnace cooling measures, which have poor cooling effect and high cost, and to provide a cooling cover and a dual-purpose furnace containing the same.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A cooling hood for cooling the interior of a dual-purpose furnace, the cooling hood comprising:

[0008] The inner tube has a first inlet and a first outlet at its two ends along the axial direction. The first inlet is used to connect with the gas collection hood inside the furnace of the dual-purpose furnace, and the first outlet extends to the outside of the furnace to discharge the exhaust gas generated by combustion inside the furnace.

[0009] The outer tube has a second inlet and a second outlet at its two ends, which are respectively fitted outside the inner tube. The second inlet is used to draw in air from outside the furnace. A gas channel is formed between the outer wall of the inner tube and the inner wall of the outer tube. The air flowing in from the second inlet is configured to flow out from the second outlet after passing through the gas channel. The second outlet is used to face the component to be cooled inside the furnace.

[0010] In this design, the cooling hood consists of an inner tube and an outer tube, resulting in a simple structure that simplifies the cooling hood's design. External air enters through the second inlet and is guided into the atmosphere of the area containing the component to be cooled. This airflow carries away heat from the component, thereby reducing its operating temperature and providing excellent cooling without damaging the component's lifespan. Furthermore, this type of cooling hood eliminates or significantly reduces the need for insulation, further reducing costs.

[0011] Preferably, the outer tube body is a bent tube structure, and has a first outer tube part and a second outer tube part, wherein the junction of the first outer tube part and the second outer tube part forms a bend.

[0012] Wherein, the second inlet is located at the end of the first outer tube portion that is away from the second outer tube portion, and the second outlet is located at the end of the second outer tube portion that is away from the first outer tube portion;

[0013] The inner tube extends through the first outer tube portion and protrudes from the side wall of the second outer tube portion.

[0014] In this scheme, the above-mentioned structural design helps to simplify the structure while minimizing the interference between exhaust gas discharge and airflow, thus ensuring the performance of the cooling hood.

[0015] Preferably, the end of the inner tube containing the first outlet extends from the end of the first outer tube portion that is away from the second outer tube portion;

[0016] And / or, the first outer tube portion and the second outer tube portion are an integral structure.

[0017] In this design, the aforementioned structure is adopted, with the first outlet in the inner tube extending from the end of the first outer tube that is furthest from the second outer tube. This means the exhaust outlet extends beyond the first outer tube, which helps prevent the discharged exhaust gas from affecting the intake air. Furthermore, integrating the first and second outer tubes into a single structure facilitates molding, further reducing costs and simplifying the structure.

[0018] Preferably, a plurality of reinforcing ribs are provided between the outer wall surface of the inner tube and the outer wall surface of the first outer tube portion;

[0019] The reinforcing ribs are spaced apart along the circumferential direction of the inner tube.

[0020] In this design, the above-mentioned structural configuration serves two purposes. First, the reinforcing ribs provide support for the inner tube, which helps ensure the relative arrangement of the inner and outer tubes. Second, the reinforcing ribs provide reinforcement, which helps ensure the overall strength of the cooling hood.

[0021] Preferably, the end of the first outer tube portion away from the second outer tube portion has a flange, and the outer tube body is used to connect to the furnace body through the flange.

[0022] In this solution, the above-mentioned structural configuration is adopted. The flange facilitates the connection between the first outer tube and the furnace body, and the flange can also increase the contact area with the furnace body, which is beneficial to the reliability of the connection between the cooling hood and the furnace body.

[0023] Preferably, the cooling cover further includes a guide positioning plate, which is connected to the outer wall of the first outer tube portion, and the guide positioning plate has a mounting position.

[0024] In this solution, the mounting position facilitates the connection between the guide positioning plate and the external structure, allowing the cooling cover to be installed in the required position conveniently and flexibly, which is beneficial for adapting to heat dissipation components in different locations.

[0025] Preferably, the outer tube is configured to switch between a locked state and an unlocked state;

[0026] When the outer tube is in the locked state, the outer tube is fixed relative to the inner tube.

[0027] When the outer tube is in the unlocked state, the outer tube can rotate relative to the inner tube to adjust the orientation of the second outlet.

[0028] In this solution, the above-mentioned structural configuration allows for flexible adjustment of the position of the outer tube relative to the inner tube according to actual needs, thereby guiding air to different areas and making it suitable for heat dissipation areas located in different regions.

[0029] Preferably, the inner wall of the inner tube is covered with a heat insulation layer, which is made of heat insulation material.

[0030] In this solution, the above-mentioned structural design can reduce the heat exchange between air and exhaust gas, resulting in a better air cooling effect.

[0031] This utility model also provides a dual-purpose furnace, including a furnace body and a gas collection hood disposed in the furnace body, characterized in that the dual-purpose furnace further includes the aforementioned cooling hood.

[0032] Preferably, the dual-purpose furnace further includes an electronic controller disposed within the furnace body, and the component to be cooled includes the electronic controller.

[0033] In this solution, the electronic controller, as an important component in the dual-purpose furnace that is prone to high temperatures, is treated as a heat dissipation component. This approach can effectively dissipate heat from the electronic controller, thereby ensuring the normal operation of the dual-purpose furnace.

[0034] The positive and progressive effects of this utility model are as follows:

[0035] In this application, the cooling hood is configured with an inner tube and an outer tube, resulting in a simple structure that simplifies the design. External air enters through the second inlet and is guided into the atmosphere of the area containing the component to be cooled. This airflow carries away heat from the component, thereby reducing its operating temperature and achieving a better cooling effect without damaging the component's lifespan. Furthermore, this type of cooling hood eliminates or significantly reduces the need for insulation, thus lowering costs. Attached Figure Description

[0058] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0059] like Figures 1 to 6 As shown, this embodiment provides a cooling hood 4 and a dual-purpose furnace including the cooling hood 4. The cooling hood 4 is used to cool the interior of the dual-purpose furnace and includes an inner tube 10 and an outer tube 20. Specifically, the inner tube 10 has a first inlet 101 and a first outlet 102 at its two ends along the axial direction. The first inlet 101 is connected to a gas collection hood 2 inside the furnace body 1 of the dual-purpose furnace, and the first outlet 102 extends to the outside of the furnace body 1 to discharge the exhaust gas generated during combustion inside the furnace body 1. The outer tube 20 has a second inlet 201 and a second outlet 202 at its two ends, respectively, and is fitted outside the inner tube 10. The second inlet 201 is used to draw in air from outside the furnace body 1. A gas channel is formed between the outer wall of the inner tube 10 and the inner wall of the outer tube 20. The air flowing in from the second inlet 201 is configured to pass through the gas channel and then flow out from the second outlet 202. The second outlet 202 is directed towards the components inside the furnace body 1 to be cooled.

[0060] In this embodiment, the cooling cover 4 is configured to include an inner tube 10 and an outer tube 20, resulting in a simple structure that simplifies the design. External air enters through the second inlet 201 and is guided into the atmosphere of the area where the component to be cooled is located. Through airflow, the heat from the component is carried away, thereby reducing the operating temperature and achieving a better cooling effect without damaging the lifespan of the component. Furthermore, this type of cooling cover 4 eliminates or significantly reduces the need for insulation cotton, thus lowering costs.

[0061] like Figure 6 As shown, in addition to the furnace body 1, the gas collection hood 2 and the cooling hood 4, the dual-purpose furnace also includes an electrical controller 3 installed in the furnace body 1, and the component to be cooled includes the electrical controller 3.

[0062] Among them, the electric controller 3 is an important component in the dual-purpose furnace that is prone to high temperature. Using it as a heat dissipation component can effectively dissipate heat from the electric controller 3, thereby helping to ensure the normal operation of the dual-purpose furnace.

[0063] Of course, the above-mentioned electronic controller 3 is only an example. In actual application, the component to be cooled can be other components in the dual-purpose furnace that need to be cooled.

[0064] It should be noted that the specific structure of the outer tube 20 and the inner tube 10 is not specifically limited in this application, as long as it can satisfy the above-mentioned reliable intake of air and reliable exhaust of waste gas.

[0065] As an example, such as Figures 1 to 5 It should be understood that the inner tube 10 is specifically a cylindrical hollow tube, and the outer tube 20 is a bent tube structure.

[0066] Specifically, the outer tube 20 has a first outer tube portion 203 and a second outer tube portion 204, with a bend forming at the junction of the first outer tube portion 203 and the second outer tube portion 204. The second inlet 201 is located at the end of the first outer tube portion 203 furthest from the second outer tube portion 204, and the second outlet 202 is located at the end of the second outer tube portion 204 furthest from the first outer tube portion 203. The inner tube 10 penetrates the first outer tube portion 203 and extends from the side wall of the second outer tube portion 204.

[0067] The above configuration helps to simplify the structure while minimizing the impact of exhaust gas discharge and airflow, thus ensuring the performance of the cooling hood 4.

[0068] Regarding the first outer tube component and the second outer tube part 204, it should be noted that the first outer tube part 203 and the second outer tube part 204 can be an integral structure, or they can be set as two independent tube components and then connected by an external connection structure.

[0069] Furthermore, such as Figures 1 to 6 As shown, the end of the inner tube 10 containing the first outlet 102 extends from the end of the first outer tube portion 203 that is furthest from the second outer tube portion 204. This arrangement, where the end of the inner tube 10 containing the first outlet 102 extends from the end of the first outer tube portion 203 that is furthest from the second outer tube portion 204, means the exhaust gas outlet extends beyond the first outer tube portion 203, which helps prevent the discharged exhaust gas from affecting the intake of air. Furthermore, integrating the first outer tube portion 203 and the second outer tube portion 204 into a single structure facilitates molding, further reducing costs and simplifying the structure.

[0070] The specific length of the first outer tube portion 203 extending from the first outlet 102 is not limited here, and can be set according to actual needs.

[0071] like Figures 1 to 2 , Figures 4 to 5 As shown, a plurality of reinforcing ribs 30 are provided between the outer wall surface of the inner tube 10 and the outer wall surface of the first outer tube portion 203. The plurality of reinforcing ribs 30 are spaced apart along the circumferential direction of the inner tube 10. As an example, this embodiment shows four evenly distributed reinforcing ribs 30.

[0072] In this embodiment, on the one hand, the reinforcing rib 30 can support the inner tube 10, which is conducive to ensuring the relative arrangement of the inner tube 10 and the outer tube 20; on the other hand, the reinforcing rib 30 can strengthen the overall strength of the cooling cover 4.

[0073] Reference Figures 1 to 6 It is understood that the end of the first outer tube portion 203 away from the second outer tube portion 204 has a flange 205, and the outer tube body 20 is used to connect to the furnace body 1 through the flange 205. Here, the flange 205 facilitates the connection between the first outer tube portion 203 and the furnace body 1, and the flange 205 can also increase the contact area with the furnace body 1, which is beneficial to the reliability of the connection between the cooling hood 4 and the furnace body 1.

[0074] In another optional embodiment, the cooling shroud 4 further includes a guide positioning plate 40, which is connected to the outer wall surface of the first outer tube portion 203. The guide positioning plate 40 has mounting positions (not shown in the figure). The number of mounting positions is not limited, nor is the specific structure of the guide positioning plate 40 limited. Figures 4 to 5 The diagram only schematically shows that the guide positioning plate 40 has an L-shaped structure.

[0075] In this implementation, the mounting position facilitates the connection between the guide positioning plate 40 and the external structure, thereby enabling the cooling cover 4 to be installed in the required position in a relatively convenient and flexible manner through the guide positioning plate 40, which is beneficial for adapting to heat dissipation components in different positions.

[0076] As another preferred configuration, the outer tube 20 is configured to switch between a locked state and an unlocked state. When the outer tube 20 is in the locked state, it is fixed relative to the inner tube 10. When the outer tube 20 is in the unlocked state, it can rotate relative to the inner tube 10 to adjust the orientation of the second outlet 202.

[0077] With the above configuration, the position of the outer tube 20 relative to the inner tube 10 can be flexibly adjusted according to actual needs, thereby guiding air to different areas and making it suitable for heat dissipation areas located in different regions.

[0078] The locking structure used to switch the outer tube 20 between the locked and unlocked states is not limited here, and any locking structure known in the prior art can be used.

[0079] Furthermore, the inner wall of the inner tube 10 is covered with a heat insulation layer made of heat insulation material. This design reduces heat exchange between the air and the exhaust gas, resulting in better air cooling. The specific material used for the heat insulation is not limited here, as long as it is suitable for this purpose.

[0080] It should be noted that the dual-purpose furnace can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the dual-purpose furnace to perform corresponding operations, thereby realizing intelligent control of the dual-purpose furnace and improving the user experience.
