Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a panel assembly and a gas stove having the same. Background Technology

[0002] Concentrated-energy gas stoves, also known as infrared gas stoves, release a large amount of infrared light waves and high-temperature flue gas during combustion to assist heating, featuring high temperature, even heating, and high efficiency. However, concentrated-energy gas stoves are quite sensitive to the characteristics of the bottom surface (heated surface) of the cookware. A shiny pot bottom can easily cause the infrared light waves released by the stove to be reflected rather than absorbed, leading to a decrease in heating efficiency. Simultaneously, the reflected infrared light can heat other components of the stove, increasing their temperature and causing problems such as reduced product stability and reliability. In particular, the black tempered glass panel carries a risk of spontaneous breakage under high temperatures. Even atmospheric gas stoves have the same risk of glass panel spontaneous breakage under high temperatures. Furthermore, high temperatures can cause users to accidentally touch the hot areas of the glass panel while cooking, resulting in burns. Summary of the Invention

[0046] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0047] The terms “a,” “one,” “the,” and “” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0048] A panel assembly according to an embodiment of the present invention, such as Figure 1-4 As shown, the panel assembly includes a glass panel 1, a heat dissipation component 2, and a fan assembly 3. The heat dissipation component 2 is connected to the bottom, and at least one heat dissipation channel is provided between the heat dissipation component 2 and the glass panel 1. Each heat dissipation channel has an air inlet end communicating with the outside. The air inlet end of the fan assembly 3 is connected to the air outlet end of the heat dissipation channel, and the air outlet end of the fan assembly 3 is also communicating with the outside. The fan assembly 3 can drive cold air into the heat dissipation channel and remove heat from the glass panel 1. In this application, the heat dissipation component 2 and the glass panel 1 are tightly fitted. The heat dissipation component 2 can be made of thermally conductive materials such as aluminum plates or metal plates. This application can evenly conduct heat from the localized high-temperature area near the furnace head 7 of the glass panel 1 to the surrounding area, maintaining a certain uniformity in the overall temperature of the glass panel 1 and preventing spontaneous breakage due to uneven stress caused by localized high temperatures. Because one or more heat dissipation channels are provided between the heat dissipation component 2 and the glass panel 1, when the temperature of the glass panel 1 reaches a preset range, the fan component 3 can cause the air in the heat dissipation channels to begin flowing. This not only removes the hot air in the heat dissipation channels but also draws in cool air from the outside, thereby removing heat from the glass panel 1 and the aluminum plate and achieving overall cooling. This application can achieve rapid cooling of the glass panel 1, ensuring stable use of the glass panel 1, preventing users from being burned by the high temperature of the glass panel 1, and improving the user experience of the kitchen stove.

[0049] In a preferred embodiment of the present invention, such as Figure 1-4The heat dissipation assembly 2 shown includes a heat dissipation plate 20. The heat dissipation plate 20 has 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. Two furnace holes 22 are formed at the bottom of the mounting groove 21. The area around the two furnace holes 22 at the bottom of the mounting groove 21 is recessed downward to form an air guide groove 23. The air guide groove 23 and the bottom of the glass panel 1 form a heat dissipation channel. The heat dissipation plate 20 of this application is preferably an aluminum plate. The heat dissipation plate 20 is closely attached to the back and side of the glass panel 1. The glass panel 1 also has furnace holes 22 for mounting the furnace head 7. Specifically, the heat dissipation plate 20 has 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 from the local high temperature area near the furnace head 7 of the glass panel 1 to the surrounding area, so that the overall high temperature of the glass panel is kept at a certain uniformity, and the glass panel 1 is prevented from spontaneously exploding due to uneven stress caused by local high temperature. Next, by recessing the bottom of the mounting groove 21 downwards to form an air guide groove 23 surrounding the furnace hole 22, a flow channel designed around the center of the furnace head 7 is formed to carry away the high temperature around the furnace head 7.

[0050] In a preferred embodiment of the present invention, such as Figure 1-4 The rear wall of the mounting slot 21 shown is provided with an air inlet 210 that connects to the heat dissipation channel, and the bottom of the air guide slot 23 is provided with an air outlet 230. The air outlet 230 is distributed between the two furnace holes 22 and connected to the air inlet end of the fan assembly 3. The rear wall of the mounting slot 21 is the corresponding slot wall at the rear end of the glass panel 1. In this way, 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 mounting slot 21, and flows along the furnace holes 22 and the center periphery of the furnace head 7, thereby carrying away the high temperature around the furnace head 7. Then, the hot air flows into the centrifugal fan 31 from the air outlet 230 and is discharged to the outside. This does not affect the atmospheric pressure inside the bottom shell of the lower air intake structure, and can quickly carry away heat to cool the glass panel 1.

[0051] In a preferred embodiment of the present invention, such as Figure 1-4The wall of the air guide trough 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 located on both sides of the plurality of furnace holes 22, and each first straight segment 231 extends from the air inlet 210 to the outer periphery of the furnace hole 22. Each arc segment 232 is arranged around the outer side of the corresponding furnace hole 22, and each arc segment 232 is 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 extend from the corresponding arc segment 232 toward the air outlet 230 and are connected to form a V-shaped structure that guides air toward the air outlet 230. The first straight section 231 can guide the cold air entering through 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 furnace head 7, thereby carrying away the high temperature around the furnace 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 exhaust it to the outside, which can quickly carry away the heat and cool down the glass panel 1.

[0052] In a preferred embodiment of the present invention, such as Figure 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 of the air guide slot 23, and the other end extends towards the air outlet 230. It is used to guide the cold air from the outside to the guide block 4 between the two furnace holes 22 and the air outlet 230. The top of the guide block 4 is in close contact with the bottom surface of the glass panel 1. Since the air outlet 230 is located between the two furnace holes 22, and the guide block 4 is located between the air inlet 210 and the air outlet 230, the cold air entering from the air inlet 210 can flow to the outer periphery of the furnace hole 22 under the guidance of the guide block 4, and then enter the air outlet 230 after passing through the outer periphery of the furnace hole 22. The structure is reasonably designed, the cooling effect is significant, and the direct entry of cold air from the air inlet 210 to the air outlet 230 will not achieve the cooling effect.

[0053] In a preferred embodiment of the present invention, such as Figure 1-4 The guide block 4 shown has a V-shaped groove 41 recessed in the direction of air intake at one end near the air outlet 230, and the V-shaped groove 41 surrounds the outer periphery of the air outlet 230. The V-shaped groove 41 can increase the travel of cold air, so that the cold air can fully absorb the heat on the burner head 7; on the other hand, it can also guide the hot air to flow towards the air outlet 230, preventing hot air from running around and entering the heat dissipation channel, which can effectively improve the heat absorption and cooling effect on the glass panel 1.

[0054] In a preferred embodiment of the present invention, such as Figure 1-4The V-shaped groove 41 shown includes two sidewalls corresponding to the two second straight segments 233. Each sidewall and the corresponding second straight segment 233 are located at the air outlet 230 and together enclose an air outlet section forming a heat dissipation channel. The flow area of ​​the air outlet section of the heat dissipation channel increases along the airflow direction. Figure 1-2 As shown, each sidewall and the corresponding second straight segment 233 are located on both sides of the air outlet 230, and an air outlet channel is formed between each sidewall and the corresponding second straight segment 233. The air outlet channel can guide the airflow entering the air outlet 230. It is not difficult to see from the figure that the air outlet channel inlet formed by the sidewall end and the corresponding second straight segment 233 has a flow area smaller than the flow area of ​​the channels on its left and right sides. That is, the flow area of ​​the heat dissipation channel first decreases at the air outlet channel inlet and then increases along the airflow direction, so that the hot air is discharged at an accelerated speed, achieving the purpose of quickly removing heat and cooling the glass panel 1.

[0055] In a preferred embodiment of the present invention, such as Figure 1-4 The air inlet end of the air guide slot 23 shown is also provided with multiple guide ribs 5. Two adjacent guide ribs 5 form an air guide channel, and the air inlet end of the air guide channel is opposite to the air inlet 210. The guide ribs 5 are evenly distributed at the air inlet end of the air guide slot 23 to guide the cold air entering through the air inlet 210, so that the cold air can move to the furnace hole 22 and the periphery of the furnace head 7, thereby achieving the purpose of removing heat from the furnace head 7 and the glass panel 1.

[0056] A gas stove according to an embodiment of the present invention, such as Figure 5-8 As shown, the gas stove includes a housing 6 and the aforementioned panel assembly, with the fan assembly 3 installed inside the housing 6. The burner head 7 is connected to the bottom of the housing 6 and passes through the burner hole 22. When the burner of this application is placed in a cabinet and the user completely seals the cabinet structure, due to the air intake at the bottom of the product, a certain negative pressure is generated in the closed cabinet cavity. This causes high-temperature flue gas to be drawn back into the secondary air supply channel for the burner's combustion operation, resulting in increased temperature and damage to the internal components of the product. It also causes incomplete combustion of the burner, emitting a large amount of CO and other exhaust gases, affecting the user's health and safety. Because the heat dissipation channel between the heat dissipation assembly 2 and the glass panel 1 of this application can be connected to the outside, sufficient air can be quickly obtained from the outside through the channel. Moreover, this channel is independent of the bottom shell, which plays a good role in stabilizing and maintaining constant internal pressure. This not only achieves rapid cooling of the glass panel 1 but also solves the problems of product safety and user health in sealed cabinets.

[0057] In a preferred embodiment of the present invention, such as Figure 5-8The housing 6 shown has an air outlet 61 corresponding to the air outlet of the fan assembly 3. Currently, existing technologies mainly rely on circulating cold air convection to cool the surface of the glass panel 1. However, this can easily affect the combustion of the burner, leading to incomplete combustion or loss of thermal efficiency. Furthermore, the convection air carries the high-temperature flue gas from the burner directly to the user, reducing the user experience and even causing some injury. This application addresses this by providing an air outlet 61 on the rear side wall of the housing 6, connected to the air outlet end of the fan assembly 3. This allows hot air in the heat dissipation channel to be quickly discharged to the outside of the gas stove through the air outlet 61 after passing through the heat dissipation channel and the fan 31. This does not affect the atmospheric pressure inside the bottom shell of the lower air intake structure, while rapidly removing heat to cool the glass panel, improving the user experience. While removing heat from the glass panel 1, it also prevents high temperatures from being transferred from the glass panel 1 to the interior of the product, indirectly reducing the temperature of internal components and improving durability and reliability.

[0058] In a preferred embodiment of the present invention, such as Figure 5-8 The guide block 4 shown is connected to the wall of the mounting groove 21, and the top of the guide block 4 abuts against the glass panel 1. An exhaust channel is provided between the guide block 4 and the glass panel 1. The exhaust channel and each heat dissipation channel are independent of each other. The air inlet of the exhaust channel is connected to the air outlet of the fan assembly 3, and the air outlet of the exhaust channel extends along the guide block 4 to the wall of the mounting groove 21. The wall of the mounting groove 21 is provided with an exhaust hole 211 corresponding to the exhaust channel, so that the exhaust channel connects to the outside of the gas stove. In this application, independent heat dissipation channels and exhaust channels are set between the heat dissipation assembly 2 and the glass panel 1. The fan 31 draws cold air into the heat dissipation channel and exhausts the hot air from the heat dissipation channel to the exhaust channel and then to the outside. This can ensure the cooling of the high-temperature area of ​​the glass panel 1 and minimize the impact on the atmospheric pressure induced by the lower air intake burner, thereby not affecting normal combustion.

[0059] In a preferred embodiment of the present invention, such as Figure 5-8The guide block 4 shown has a downward-curving center to form an exhaust groove 42. The glass panel 1 covers the top of the exhaust groove 42, and the exhaust groove 42 and the glass panel 1 together form an exhaust channel. The exhaust groove 42 has an air passage 421 that connects to the air outlet of the fan assembly 3. By setting the exhaust groove 42 in the guide block 4, cold air enters the glass panel 1 and the heat dissipation assembly 2 from the left and right sides of the guide block 4, surrounds the outer periphery of the burner head 7, and then enters the fan 31. The fan 31 and the air passage 421 transport the hot air to the exhaust groove 42 and then discharge it to the outside. This method does not affect the atmospheric pressure inside the bottom shell of the lower air intake structure, while quickly removing heat to cool the glass panel 1. This solution removes heat from the glass panel 1 while preventing high temperatures from being transferred from the glass panel 1 to the interior of the product, indirectly reducing the temperature of the internal components, improving durability and reliability, minimizing the impact on the atmospheric pressure induced by the lower air intake burner, and improving the user experience.
