Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a panel assembly and a gas stove having the same. Background Art

[0002] Energy-gathering stoves, also known as infrared gas stoves, can release a large amount of infrared light waves and high-temperature smoke to assist heating during combustion. They have the characteristics of high temperature, uniform heating and high efficiency. However, energy-gathering stoves are more sensitive to the characteristics of the bottom surface (heating surface) of the pot. The bright bottom of the pot easily reflects the infrared light waves released by the combustion of the energy-gathering stove instead of being absorbed, resulting in reduced heating efficiency of the gas stove. At the same time, the reflected infrared light will heat other parts of the stove, causing the temperature of each component of the product to rise, resulting in problems such as reduced product stability and reliability. In particular, black tempered glass panels are at risk of self-explosion under high temperature conditions. Even for atmospheric gas stoves, there is also the risk of glass panels self-exploding under high temperature conditions. At the same time, high temperature conditions can cause users to accidentally touch the high-temperature area of ​​the glass panel when cooking, resulting in burns. Utility Model Content

The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0047] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0048] A panel assembly according to an embodiment of the utility model, such as Figures 1-4 As shown, the panel assembly includes a glass panel 1, a heat dissipation assembly 2 and a fan assembly 3. Below the connection of the heat dissipation assembly 2, at least one heat dissipation channel is provided between the heat dissipation assembly 2 and the glass panel 1. Each heat dissipation channel has an air inlet end communicating with the outside world. The air inlet end of the fan assembly 3 is connected to the air outlet end of the heat dissipation channel. The air outlet end of the fan assembly 3 is communicated with the outside world. The fan assembly 3 can drive cold air into the heat dissipation channel and take away the heat of the glass panel 1. In the present application, the heat dissipation assembly 2 and the glass panel 1 are tightly fitted. The heat dissipation assembly 2 can be made of heat-conductive aluminum plates, metal plates and other materials. The present application can evenly conduct the heat of the local high-temperature area of ​​the glass panel 1 near the furnace head 7 to the surrounding areas, so that the high temperature of the glass panel 1 is kept uniform as a whole, and avoid the glass panel 1 from self-exploding due to uneven stress caused by the local high temperature. Since one or more heat dissipation channels are arranged between the heat dissipation component 2 and the glass panel 1, when the temperature of the glass panel 1 reaches a preset range, the air in the heat dissipation channel can start to flow through the fan component 3, which not only takes away the hot air in the heat dissipation channel, but also draws the cold air from the outside into the heat dissipation channel, thereby taking away the heat of the glass panel 1 and the aluminum plate, and playing the role of overall cooling. The present application can achieve rapid cooling of the glass panel 1, ensure the stable use of the glass panel 1, avoid the high temperature of the glass panel 1 from scalding the user, and improve the user experience of the kitchen stove.

[0049] In a preferred embodiment of the present invention, Figures 1-4The heat dissipation assembly 2 shown includes a heat dissipation plate 20, the heat dissipation plate 20 is provided with a mounting groove 21 for mounting the glass panel 1, one side of the glass panel 1 is inserted into and abuts against the bottom of the mounting groove 21, the bottom of the mounting groove 21 is provided with two furnace holes 22, the bottom of the mounting groove 21 is arranged around the area around the two furnace holes 22 and is recessed downward to form an air guide groove 23, the air guide groove 23 and the bottom of the glass panel 1 are arranged to form a heat dissipation channel. The heat dissipation plate 20 of the present application is preferably an aluminum plate, the heat dissipation plate 20 is tightly attached to the back and side of the glass panel 1, the glass panel 1 is also provided with a furnace hole 22 for mounting the furnace head 7, specifically, the heat dissipation plate 20 is provided with a mounting groove 21, the glass panel 1 is inserted into the mounting groove 21 and abuts against the bottom of the mounting groove 21, the heat dissipation plate 20 can evenly conduct the heat of the local high temperature area of ​​the glass panel 1 near the furnace head 7 to the surrounding area, so that the high temperature of the glass panel as a whole maintains a certain uniformity, and avoids the self-explosion of the glass panel 1 due to the uneven stress of the local high temperature. Then, the bottom of the installation groove 21 is depressed downward to form an air guide groove 23 around the furnace hole 22 to form a flow channel designed along the central periphery of the furnace head 7 to remove the high temperature around the furnace head 7.

[0050] In a preferred embodiment of the present invention, Figures 1-4 The rear groove wall of the installation groove 21 shown is provided with an air inlet 210 connected to the heat dissipation channel, and the groove bottom of the air guide groove 23 is provided with an air outlet 230, which is distributed between the two furnace holes 22 and connected to the air inlet end of the fan assembly 3. The rear groove wall of the installation groove 21 is the groove wall corresponding to the rear end of the glass panel 1, so that air flows into the heat dissipation channel from the air inlet 210 at the rear end of the glass panel 1, enters the interior of the installation groove 21 and flows along the center periphery of the furnace hole 22 and the upper furnace head 7, thereby taking away the high temperature around the furnace head 7, and then the hot air flows into the centrifugal fan 31 from the air outlet 230 and is discharged to the outside, which does not affect the atmospheric pressure inside the bottom shell of the lower air inlet structure, and can quickly take away the heat to cool the glass panel 1.

[0051] In a preferred embodiment of the present invention, Figures 1-4The groove wall of the air guide groove 23 shown includes two first straight segments 231, two arc segments 232 and two second straight segments 233. The two first straight segments 231 are respectively located on both sides of the multiple furnace holes 22, and each first straight segment 231 extends from the air inlet hole 210 to the outer periphery of the furnace hole 22; each arc segment 232 is respectively arranged on the outer side of the corresponding furnace hole 22, and each arc segment 232 is respectively connected to the other end of the corresponding first straight segment 231; each second straight segment 233 is located between the two arc segments 232, and the two second straight segments 233 respectively extend from the corresponding arc segment 232 toward the air outlet hole 230, and are connected to form a V-shaped structure for guiding air toward the air outlet hole 230. The first straight section 231 can guide the cold air entering from the air inlet 210 to the arc section 232, so that the cold air can flow along the furnace hole 22 and the periphery of the burner head 7 thereon, thereby taking away the high temperature around the burner head 7; then the second straight section 233 can guide the hot air in the arc section 232 to the air outlet 230 and the fan 31 and then be discharged to the outside, which can quickly take away the heat to cool the glass panel 1.

[0052] In a preferred embodiment of the present invention, Figures 1-4 The panel assembly shown also includes a guide block 4, which is located between the two furnace holes 22. One end of the guide block 4 is connected to the air inlet end of the air guide groove 23, and the other end extends to the air outlet 230, which is used to guide the cold air from the outside to the two furnace holes 22 and the guide block 4 of the air outlet 230. The top of the guide block 4 is tightly attached to the bottom surface of the glass panel 1. Since the air outlet 230 is located between the two furnace holes 22, the guide block 4 is located between the air inlet 210 and the air outlet 230. In this way, the cold air entering from the air inlet 210 can flow to the outer periphery of the furnace hole 22 under the guiding effect of the guide block 4, and after passing through the outer periphery of the furnace hole 22, it enters the air outlet 230. The structural design is reasonable and the cooling effect is significant, which prevents the cold air from directly entering the air outlet 230 from the air inlet 210 and failing to achieve the cooling effect.

[0053] In a preferred embodiment of the present invention, Figures 1-4 The guide block 4 shown has a V-shaped groove 41 recessed in the air inlet direction at one end close to the air outlet 230, and the V-shaped groove 41 is arranged around the outer periphery of the air outlet 230. The V-shaped groove 41 can increase the travel of the cold air, so that the cold air can fully absorb the heat on the burner 7; on the other hand, it can also guide the hot air to flow toward the air outlet 230, preventing the hot air from rushing into the heat dissipation channel, and can effectively improve the heat absorption and cooling effect on the glass panel 1.

[0054] In a preferred embodiment of the present invention, Figures 1-4The V-shaped groove 41 shown includes two side walls corresponding to the two second straight segments 233. Each side wall and the corresponding second straight segment 233 are respectively located at the air outlet hole 230 and jointly enclose the air outlet section of the heat dissipation channel. Among them, the cross-sectional area of the air outlet section of the heat dissipation channel increases along the air flow direction. As Figures 1-2 shown, each side wall and the corresponding second straight segment 233 are respectively located on both sides of the air outlet hole 230, and an air outlet channel is formed between each side wall and the corresponding second straight segment 233. The air outlet channel can guide the air flow entering the air outlet hole 230. It is not difficult to see from the figure that the air inlet end of the air outlet channel is formed by the end of the side wall and the corresponding second straight segment 233. The cross-sectional area of the air inlet end of this air outlet channel is smaller than the cross-sectional areas of the channels on its left and right sides, that is, the cross-sectional area of the heat dissipation channel first becomes smaller at the air inlet end of the air outlet channel and then increases along the air flow direction, so that the derived hot air has an accelerated discharge, achieving the purpose of quickly taking away heat to cool the glass panel 1.

[0055] In a preferred embodiment of the present invention, as Figures 1-4 shown, a plurality of guiding ribs 5 are further provided at the air inlet end of the air guiding groove 23. Adjacent two guiding ribs 5 form an air guiding channel, and the air inlet end of the air guiding channel faces the air inlet hole 210. The guiding ribs 5 are evenly distributed at the air inlet end of the air guiding groove 23 to guide the cold air entering from the air inlet hole 210, so that the cold air can move to the periphery of the furnace hole 22 and the burner 7 thereon, achieving the purpose of taking away the heat of the burner 7 and the glass panel 1.

[0056] A gas stove according to an embodiment of the present invention, as Figures 5-8 shown, the gas stove includes a housing 6 and the above-mentioned panel assembly. The fan assembly 3 is installed inside the housing 6. The bottom of the burner 7 is connected to the housing 6 and passes through the furnace hole 22. When the burner of the present application is placed in a cabinet and the user completely seals the cabinet structure, due to the relationship of the primary air induced by the downward air inlet of the product, a certain negative pressure is generated in the closed cabinet cavity, resulting in the backflow of high-temperature flue gas in the secondary air supply channel for the burner to burn, thereby increasing the temperature of the internal components of the product and causing damage, and also making the burner burn incompletely, discharging a large amount of waste gases such as CO, affecting the user's use health and safety. Since the heat dissipation channel between the heat dissipation component 2 and the glass panel 1 of the present application can communicate with the outside world, sufficient air can be quickly obtained from the outside through the channel, and this channel is independent of the inside of the bottom shell, playing a good role in stabilizing and maintaining the internal constant pressure, not only quickly cooling the glass panel 1, but also solving the problems of the use safety and user health of the closed cabinet product.

[0057] In a preferred embodiment of the present invention, as Figures 5-8The shown housing 6 is provided with an air outlet hole 61 corresponding to the air outlet of the fan assembly 3. Currently, in the prior art, the surface of the glass panel 1 is mainly cooled by relying on the circulating cold air convection. However, this is likely to affect the combustion of the burner, resulting in incomplete combustion of the burner or heat efficiency loss. In addition, the convective air drives the high-temperature flue gas of the burner to directly blow on the human body, reducing the user experience or even causing certain damage. In this application, the air outlet hole 61 is provided on the rear side wall of the housing 6, and the air outlet hole 61 is connected to the air outlet end of the fan assembly 3, so that the hot air in the heat dissipation flow channel is quickly discharged to the outside of the gas stove through the heat dissipation flow channel and the fan 31. It neither affects the atmospheric pressure inside the bottom shell of the under-inlet air structure, nor can quickly take away heat to cool the glass panel, improving the user experience. While taking away the heat of the glass panel 1, it can also prevent the high temperature from being transferred from the glass panel 1 to the inside of the product, indirectly reducing the temperature of each component inside the product and improving the durability and reliability.

[0058] In a preferred embodiment of the present utility model, as Figures 5-8 shown, the guide block 4 is connected to the groove wall of the installation groove 21, and the top of the guide block 4 abuts against the glass panel 1. An exhaust passage is provided between the guide block 4 and the glass panel 1, and the exhaust passage and each heat dissipation flow channel are independent of each other; wherein, the inlet end of the exhaust passage communicates with the air outlet of the fan assembly 3, and the outlet end of the exhaust passage extends along the guide block 4 to the groove wall of the installation groove 21. The groove wall of the installation groove 21 is provided with an exhaust hole 211 corresponding to the exhaust passage, so that the exhaust passage communicates with the outside of the gas stove. In this application, an independent heat dissipation flow channel and an exhaust passage are provided between the heat dissipation assembly 2 and the glass panel 1. The fan 31 sucks the cold air into the heat dissipation flow channel and discharges the hot air in the heat dissipation flow channel to the exhaust passage and then to the outside world, which can not only ensure the cooling of the high-temperature area of the glass panel 1, but also minimize the impact on the atmospheric pressure of the under-inlet burner injection environment, thus not affecting the normal combustion.

[0059] In a preferred embodiment of the present utility model, as Figures 5-8In the middle of the guiding block 4 shown, a downward depression is formed to form an exhaust groove 42. The glass panel 1 is covered on the top of the exhaust groove 42, and the exhaust groove 42 and the glass panel 1 enclose to form an exhaust passage. Among them, the exhaust groove 42 is provided with an air passing hole 421 communicating with the air outlet end of the fan assembly 3. By arranging the exhaust groove 42 on the guiding block 4, cold air enters from the left and right sides of the guiding block 4 into the inside of the glass panel 1 and the heat dissipation assembly 2, surrounds the outer periphery of the burner 7, and then enters the fan 31. The hot air is conveyed to the exhaust groove 42 by the fan 31 and the air passing hole 421 and then discharged to the outside. This not only does not affect the atmospheric pressure inside the bottom shell of the lower air inlet structure, but also can quickly take away heat to cool the glass panel 1. While taking away the heat of the glass panel 1, this solution can also prevent high temperature from being transferred from the glass panel 1 to the inside of the product, indirectly reducing the temperature of each component inside the product, improving durability and reliability, minimizing the impact on the atmospheric pressure of the lower air inlet burner's injection environment, and enhancing the user experience.
