Description

Technical Field

[0001] This utility model relates to the field of stoves, and in particular to a stove. Background Technology

[0002] Currently, the load on direct-insertion valve burners in gas stoves is increasing. As a safety and airtight component, the valve body has some rubber parts and grease coatings that have sealing functions that are subject to temperature requirements. Excessive temperature can lead to a decrease in their function or failure.

[0003] A direct-injection valve comprises a valve seat, valve tube assembly, and nozzle. A key characteristic of direct-injection valves is their direct contact with the burner; heat is transferred to the valve through conduction and radiation, resulting in a relatively high temperature. Therefore, temperature control is crucial to ensuring the lifespan and reliability of the valve's seals.

[0004] To control the temperature, existing technologies use methods such as heat insulation covers, cooling holes near the chassis, or installing fans. However, the heat insulation effect of heat insulation covers and cooling effect of chassis openings are poor, and the cost of installing fans is relatively high. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing direct-insertion valve cooling method, which cannot balance cooling effect and cost, and to provide a stove.

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

[0007] A stove includes a chassis, an ejector tube, a nozzle, and a valve tube, wherein one end of the nozzle is connected to the valve tube and the other end of the nozzle is connected to the ejector tube;

[0008] The stove also includes a flow guiding component, which includes a top plate, a first side plate, and a second side plate. The first side plate and the second side plate are respectively connected to the top plate. The bottom ends of the first side plate and the second side plate extend to the chassis. The first side plate, the top plate, the second side plate, and the chassis are sequentially arranged to form a flow channel.

[0009] In the vertical direction, the highest point of the flow channel is flush with the highest point of the ejector tube opening;

[0010] Along the width direction of the ejector tube, the first surface of the first side plate opposite to the second side plate and the second surface of the second side plate opposite to the first side plate are respectively flush with both sides of the tube opening along the width direction;

[0011] Along the ejection direction of the ejector tube, there is a gap between the flow guiding assembly and the tube opening;

[0012] The nozzle is at least partially located within the flow channel, and the valve tube is at least partially located within the flow channel.

[0013] In this technical solution, by setting up a flow guiding component and utilizing the Venturi effect of the ejector tube, a wind-cooling system without additional power consumption is formed. The flow channel formed by the flow guiding component changes the air domain range ejected by the ejector tube, realizing directional airflow. The air ejected by the ejector tube changes from the original diffusion flow to directional flow within the flow channel. The nozzle and valve tube are set in the flow channel, which can utilize the airflow for cooling. At the same time, the upper end of the flow guiding channel is flush with the nozzle opening, and the two sides of the flow guiding component are also flush with the two sides of the ejector tube. The small cross-sectional area of ​​the flow channel helps to increase the air velocity, thereby enhancing the cooling effect of the air on the valve tube and nozzle. This flow guiding component has a good cooling effect on both the nozzle and valve tube, and requires no additional power source, resulting in low cost.

[0014] Preferably, the ejector tube includes a first ejector tube and a second ejector tube, the first ejector tube and the second ejector tube are arranged in parallel, the first surface is flush with the opening of the first ejector tube and the side away from the second ejector tube, and the second surface is flush with the opening of the second ejector tube and the side away from the first ejector tube.

[0015] In this technical solution, with dual ejector tubes, the flow guiding component is made into a single channel, which simplifies the structure of the entire flow guiding component.

[0016] Preferably, the stove further includes a first connector and a second connector, the valve pipe includes a first valve pipe and a second valve pipe, the first connector is disposed between the first valve pipe and the second valve pipe and connects the first valve pipe and the second valve pipe, and the second connector connects the flow guiding assembly and the first connector.

[0017] Preferably, the lower surface of the top plate is recessed downward to form a recessed portion, the lower surface of the recessed portion abuts against the first connector, the recessed portion has a first connecting hole, the first connector has a second connecting hole, and the second connector connects the flow guiding assembly and the first connector through the first connecting hole and the second connecting hole.

[0018] In this technical solution, by recessing the top plate downwards to form a recessed portion that abuts against the first connector, and connecting the airflow guiding component and the first connector via a second connector, the connection distance between the airflow guiding component and the first connector can be shortened, and the size of the second connector can be reduced. Simultaneously, the recessed portion can also reduce the cross-sectional area of ​​the airflow channel, further increasing the airflow velocity and improving the cooling effect.

[0019] Preferably, the flow guiding component is integrally formed, and the flow guiding component is formed by bending a steel plate of uniform thickness.

[0020] Preferably, the upper surface of the first connector is horizontally positioned;

[0021] The recessed portion includes a first sidewall, a bottom wall, and a second sidewall connected in sequence. The bottom wall is horizontally arranged and abuts against the first connector. Along the width direction, the width of the bottom wall is not less than 10mm.

[0022] In this technical solution, by setting the lower surface of the first connector and the lower surface of the bottom wall to be horizontal, the contact area between the first connector and the bottom wall can be increased. At the same time, by setting the width of the bottom wall to not less than 10mm, the contact area between the bottom wall and the first connector is sufficient, which facilitates the connection between the first connector and the flow guiding component and makes the connection more reliable.

[0023] Preferably, the angle between the first sidewall and the bottom wall is α, where α ≥ 100°.

[0024] Preferably, the angle between the second sidewall and the bottom wall is β, where β ≥ 100°.

[0025] Preferably, the cooktop further includes a third connecting component that connects the flow guiding component and the chassis.

[0026] Preferably, the third connecting assembly includes at least two screws and two connecting pieces respectively connected to the bottom end of the first side plate and the bottom end of the second side plate, wherein the screws connect the connecting pieces and the chassis.

[0027] In this technical solution, connecting pieces are respectively set at the bottom end of the first side plate and the bottom end of the second side plate to achieve connection with the chassis, making the connection of the flow guiding component more reliable.

[0028] Preferably, along the ejection direction, the distance between the flow guiding component and the nozzle is d, where 8mm ≤ d ≤ 10mm.

[0029] In this technical solution, by setting the distance between the flow guiding component and the nozzle of the ejector tube to between 8mm and 10mm, it is ensured that the flow guiding component and the ejector tube do not come into contact, thereby reducing the heat transferred from the ejector tube to the flow guiding component. At the same time, it avoids the flow guiding component being too far from the nozzle of the ejector tube and the air space being too small, which would reduce the utilization rate of air.

[0030] The positive and progressive effects of this utility model are as follows:

[0031] By setting up a flow guiding component and utilizing the Venturi effect of the ejector tube, a wind-cooling system that requires no additional power consumption is formed. The flow channel formed by the flow guiding component changes the range of air ejected by the ejector tube, realizing directional airflow. The air ejected by the ejector tube changes from the original diffusion flow to directional flow in the flow channel. The nozzle and valve tube are set in the flow channel, which can utilize the airflow for cooling. At the same time, the upper end of the flow guiding channel is flush with the nozzle opening, and the two sides of the flow guiding component are also flush with the two sides of the ejector tube. The cross-sectional area of ​​the flow channel is small, which helps to increase the air velocity, thereby enhancing the cooling effect of the air on the valve tube and nozzle.

[0056] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0057] like Figures 1-5 As shown, this embodiment provides a cooktop, which includes a chassis 1, an injection tube 2, a nozzle 4, and a valve tube 3. One end of the nozzle 4 is connected to the valve tube 3, and the other end of the nozzle 4 is connected to the injection tube 2. The cooktop also includes a flow guiding assembly 5, such as... Figure 5 As shown, the flow guiding assembly 5 includes a top plate 51, a first side plate 52, and a second side plate 53. The first side plate 52 and the second side plate 53 are respectively connected to the top plate 51. The bottom ends of both the first side plate 52 and the second side plate 53 extend to the chassis 1. The first side plate 52, the top plate 51, the second side plate 53, and the chassis 1 sequentially enclose to form a flow channel. Vertically, the highest point of the flow channel is flush with the highest point of the inlet of the ejector tube 2. Figure 5 and Figure 6 As shown, along the width direction of the ejector tube 2, the first surface of the first side plate 52 opposite to the second side plate 53, and the second surface of the second side plate 53 opposite to the first side plate 52, are respectively flush with both sides of the nozzle along the width direction; along the ejection direction of the ejector tube 2, there is a gap between the flow guiding assembly 5 and the nozzle. The nozzle 4 is at least partially located in the flow channel, and the valve tube 3 is at least partially located in the flow channel.

[0058] By incorporating the Venturi effect of the ejector tube 2, the flow guiding component 5 creates a wind-cooling system that requires no additional power. The flow channel formed by the flow guiding component 5 alters the air domain of the ejector tube 2, achieving directional airflow. The air ejected by the ejector tube 2 changes from a diffused flow to a directional flow within the channel. The nozzle 4 and valve tube 3, positioned within this flow channel, utilize the airflow for cooling. Furthermore, the upper end of the flow guiding channel is flush with the inlet of the ejector tube 2, and the sides of the flow guiding component 5 are also flush with the sides of the ejector tube 2. The small cross-sectional area of ​​the flow channel contributes to increased air velocity, thereby enhancing the cooling effect on the valve tube 3 and nozzle 4. This flow guiding component 5 influences the primary air's flow domain, direction, and velocity, causing them to change in domain, direction, and speed, achieving directional, fixed-velocity flow guidance. This provides excellent cooling for both the nozzle 4 and valve tube 3 without requiring an additional power source, resulting in low cost.

[0059] In this embodiment, as Figure 3 As shown, the ejector tube 2 includes a first ejector tube 21 and a second ejector tube 22, which are arranged in parallel. The first surface of the ejector tube 21 is flush with the opening of the first ejector tube 21 and the side away from the second ejector tube 22, and the second surface is flush with the opening of the second ejector tube 22 and the side away from the first ejector tube 21. In the case of dual ejector tubes 2, the flow guiding assembly 5 is made into a single-channel form, which simplifies the structure of the entire flow guiding assembly 5.

[0060] Of course, in other embodiments, two flow guiding components 5 may be provided corresponding to the first ejector tube 21 and the second ejector tube 22 respectively. The flow channel of one flow guiding component 5 is corresponding to the first ejector tube 21 and has the same width, and the flow channel of the other flow guiding component 5 is corresponding to the second ejector tube 22 and has the same width. This will not be described in detail here.

[0061] In this embodiment, as Figure 3 As shown, the stove also includes a first connector 6 and a second connector. The valve pipe includes a first valve pipe 31 and a second valve pipe 32 arranged in parallel. The first connector 6 is disposed between the first valve pipe 31 and the second valve pipe 32 and connects the first valve pipe 31 and the second valve pipe 32. The second connector connects the flow guiding assembly 5 and the first connector 6.

[0062] Specifically, in this embodiment, the lower surface of the top plate 51 is recessed downwards to form a recessed portion 501. The lower surface of the recessed portion 501 abuts against the first connecting member 6. The recessed portion 501 has a first connecting hole, and the first connecting member 6 has a second connecting hole. The second connecting member connects the flow guiding assembly 5 and the first connecting member 6 through the first connecting hole and the second connecting hole. By recessing the top plate 51 downwards to form the recessed portion 501 that abuts against the first connecting member 6, and connecting the flow guiding assembly 5 and the first connecting member 6 through the second connecting member, the connection distance between the flow guiding assembly 5 and the first connecting member 6 can be shortened, and the size of the second connecting member can be shortened. At the same time, the recessed portion 501 can also reduce the cross-sectional area of ​​the flow guiding channel, further increasing the airflow velocity and improving the cooling effect.

[0063] Of course, in other embodiments, the top plate 51 of the flow guiding component 5 can also be set to horizontal, and the first connector 6 can be extended upward to abut against the top of the flow guiding component 5 and then connected by the second connector, which will not be described in detail here.

[0064] In this embodiment, the flow guiding component 5 is integrally formed, and specifically, the flow guiding component 5 is formed by bending a steel plate of uniform thickness.

[0065] Wherein, the angle between the first sidewall 512 and the bottom wall 511 is α, and the value of α is not less than 100°; the angle between the second sidewall 513 and the bottom wall 511 is β, and the value of β is not less than 100°. Specifically in this embodiment, as... Figure 5 As shown, α and β are both 100°. By setting the range of values ​​for α and β to be no less than 100°, the excessive integrity of the flow guiding component 5 is avoided, which would reduce the structural strength.

[0066] In this embodiment, as Figure 3 As shown, the recessed portion 501 includes a first sidewall 512, a bottom wall 511, and a second sidewall 513 connected in sequence. The bottom wall 511 is horizontally arranged, and the upper surface of the first connector 6 is also horizontally arranged. The bottom wall 511 abuts against the first connector 6, and the width of the bottom wall 511 is not less than 10mm along the width direction. By setting the lower surface of the first connector 6 and the lower surface of the bottom wall 511 to be horizontal, the contact area between the first connector 6 and the bottom wall 511 can be increased. At the same time, setting the width of the bottom wall 511 to not less than 10mm ensures that the contact area between the bottom wall 511 and the first connector 6 is sufficient, which facilitates the connection between the first connector 6 and the flow guiding assembly 5 and makes the connection more reliable.

[0067] Specifically, in this embodiment, the width of the bottom wall 511 is set to 15mm, and the second connecting member can be a bolt or pin, etc., as in the prior art, which will not be described in detail here.

[0068] Of course, in other embodiments, the cooktop may also include a third connecting component (not shown in the figure), which connects the flow guiding component 5 and the chassis 1. Specifically, the third connecting component includes at least two screws and two connecting pieces respectively connected to the bottom end of the first side plate 52 and the bottom end of the second side plate 53. The screws connect the connecting pieces to the chassis 1. By providing connecting pieces at the bottom ends of the first side plate 52 and the second side plate 53, the connection with the chassis 1 is achieved, making the connection of the flow guiding component 5 more reliable. Alternatively, in more embodiments, the first connecting piece 6 and the second connecting piece may not be provided; the flow guiding component 5 can be fixed to the chassis 1 by the third connecting component.

[0069] For the extension position of the flow guiding component 5 along the ejection direction, such as Figure 4 As shown, the distance between the flow guiding component 5 and the pipe opening is d, where 8mm ≤ d ≤ 10mm. The end of the flow guiding component 5 furthest from the pipe opening is not limited. The longer the valve pipe 3 is within the flow channel, the better the cooling effect of the flow channel on the valve pipe 3. By setting the distance between the flow guiding component 5 and the pipe opening of the ejector tube 2 to between 8mm and 10mm, it is ensured that the flow guiding component 5 and the ejector tube 2 do not contact each other, reducing the heat transferred from the ejector tube 2 to the flow guiding component 5. Simultaneously, it avoids the flow guiding component 5 being too far from the pipe opening of the ejector tube 2, resulting in a small air space and reduced air utilization.

[0070] The stove 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 stove to perform corresponding operations, thereby realizing intelligent control of the stove and improving the user experience.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
