Description

Technical Field

[0001] The utility model relates to the field of stoves, in particular to a stove table top and a stove comprising the same. Background Art

[0002] In the prior art, there are stoves on the market that use tempered glass as the tabletop. Using tempered glass as the stove tabletop has the advantages of being beautiful, easy to clean, and scratch-resistant. However, compared with using other materials as the stove tabletop, stoves using tempered glass have the risk of thermal explosion. The main reason for thermal explosion is that when the temperature of the tempered glass is too high or the internal stress is too high, if a cold or hot shock occurs, such as when the hot panel contacts normal temperature water, or when the panel temperature difference is too large and the internal stress of the panel is too large, there is a risk of explosion.

[0003] Thermal explosion may cause debris to splash, which may threaten the personal and property safety of users and needs to be overcome urgently. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect of the prior art that when the tempered glass temperature is too high or the internal stress is too high, there is a risk of explosion if a thermal shock occurs, such as when the hot panel contacts normal temperature water, or when the internal stress of the panel is too large due to a large temperature difference, and to provide a stove top and a stove containing the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A stove top, comprising a tempered glass panel, is characterized in that it comprises:

[0007] A conduction heat dissipation part, which is arranged on a side of the tempered glass panel facing the inside of the cooker and can conduct heat;

[0008] The reflective heat-insulating part is arranged on a side of the tempered glass panel facing the outside of the cooker and can reflect and insulate heat radiation.

[0009] In this solution, the above structure is adopted. The heat source of the tempered glass panel of the stove is the combustion of the burner. It is mainly divided into two heat transfer modes, heat conduction and heat radiation. Heat conduction mainly transfers heat to the tempered glass panel through the pot support and the overflow tray, and heat radiation mainly radiates the combustion flame and high-temperature smoke to the tempered glass panel. The conductive heat dissipation part is made of high thermal conductivity material. The high thermal conductivity material is set on the back of the tempered glass panel to quickly absorb the high-temperature heat of the tempered glass panel and can quickly dissipate the heat. The reflective insulation part is made of low thermal conductivity material and is set on the front of the glass to reduce the absorption of radiation waves, increase the reflection of radiation waves, and thus reduce the absorption of radiant heat from the burner. Reduce the heat conduction and heat transfer of the tempered glass panel to achieve a cooling effect, thereby reducing the overall temperature difference of the tempered glass panel, avoiding thermal explosions, and being safer.

[0010] Preferably, the conductive heat dissipation portion is black; and / or

[0011] The reflective heat insulation part is white.

[0012] In this solution, the above structure is adopted. The same color has different abilities to absorb electromagnetic radiation. White absorbs heat slowly and dissipates heat slowly, while black is the opposite. Placing black high thermal conductivity material on the back of the glass for heat dissipation can accelerate the cooling of the high temperature area of ​​the glass. Placing white low thermal conductivity material on the front of the glass can reduce the absorption of radiation waves and increase the reflection of radiation waves, thereby reducing the absorption of the radiant heat of the burner.

[0013] Preferably, the side of the reflective heat insulation portion facing outside the cooker is a mirror surface.

[0014] In this solution, the above structure is adopted, and the mirror-like low thermal conductivity material is set on the front side of the glass to further reduce the absorption of radiation waves, increase the reflection of radiation waves, and thus reduce the absorption of the radiant heat of the burner.

[0015] Preferably, the thickness of the reflective heat-insulating portion is greater than the thickness of the conductive heat-dissipating portion.

[0016] In this solution, the above structure is adopted, and the thermal conductivity and material thickness are inversely related, which means that when the material thickness increases, its thermal conductivity will decrease. Reasonable thickness is one of the factors to control temperature. Relatively thin materials can be selected for the back heat dissipation material, which can be more conducive to the conduction heat dissipation part absorbing heat and dissipating heat. Relatively thick materials are selected for the front side, which can be more conducive to the reflective insulation part isolating heat radiation and reducing heat absorption.

[0017] Preferably, the stove top further comprises an air barrier, and the air barrier is arranged between the stove burner and the tempered glass panel.

[0018] In this solution, the above structure is adopted, and the air barrier is a cavity relatively sealed from the outside, and the cavity is filled with air, and the low thermal conductivity of air is used to block heat. It is arranged between the stove head and the tempered glass panel to slow down the heat transfer between the stove head and the tempered glass panel, and reduce the heat absorption of the tempered glass panel.

[0019] Preferably, the stove top further comprises an overflow pan arranged around the stove head, the edge of the overflow pan protrudes upward to form a raised portion, and the air barrier is formed in a cavity between the raised portion of the overflow pan and the tempered glass panel.

[0020] In this solution, the above-mentioned structure is adopted, and the air barrier is set in the protrusion of the overflow tray. The overflow tray itself needs to be set around the burner head and have a certain protrusion. The air barrier is set by using the space of the protrusion to better isolate the burner head and the tempered glass panel, and at the same time the space utilization rate is higher.

[0021] Preferably, the stove top also includes a partition frame, which includes a frame body and a plurality of barrier plates, the frame body covers the tempered glass panel, the plurality of barrier plates are sealed to the top surface and / or the side surface of the tempered glass panel, and two adjacent barrier plates, the frame body and the tempered glass panel define the air barrier.

[0022] In this solution, the above structure is adopted, and the air barrier is formed by the partition frame, the frame body of the partition frame covers the tempered glass panel, and the frame body has a plurality of blocking plates. After the blocking plates are against the tempered glass panel, the space between the tempered glass panel, the blocking plates, and the frame body forms a closed and sealed space, thereby forming an air barrier. According to the different sealing positions of the blocking plates and the tempered glass panel, the air barrier can be formed on the top surface or the side surface of the tempered glass panel, and the heat transfer can be reduced in both the height direction and the horizontal direction.

[0023] Preferably, a through slot is formed on the tempered glass panel, the stove head is arranged in the through slot, and the partition covers the edge of the through slot.

[0024] In this solution, the above structure is adopted, and the tempered glass panel stove head opening can avoid the high temperature area. The opening size and the front heat insulation component cooperate with each other to achieve the minimum heat absorption within the coverage range of the liquid tray. The partition frame is set at the edge of the through slot, which can reduce heat transfer in both the height direction and the horizontal direction.

[0025] Preferably, the area of ​​the stove top close to the ejector tube of the stove is a high-heat area, the area of ​​the stove top away from the ejector tube is a low-heat area, and the conductive heat dissipation part and / or the reflective heat insulation part at least cover the high-heat area.

[0026] In this solution, the above structure is adopted. When the gas cooker is burning normally, the temperature area of ​​the glass panel shows a trend of gradually decreasing with the burner as the center, and changes with the distribution of the burner ejector tube and the ignition distributor flow channel structure. The temperature near the ejector tube outlet is in the higher temperature area of ​​the entire panel. If the highest temperature in this area can be reduced, the temperature rise of the entire panel can be reduced and the temperature difference of the panel can be reduced. Targetedly arranging the conduction heat dissipation part and the reflective heat insulation part in these high-heat areas has a better heat dissipation effect and reduces the overall temperature difference of the glass panel.

[0027] A stove is characterized in that it comprises the stove tabletop as described in any one of the above items.

[0028] In this solution, the above structure is adopted. The heat source of the tempered glass panel of the stove is the combustion of the burner. It is mainly divided into two heat transfer modes, heat conduction and heat radiation. Heat conduction mainly transfers heat to the tempered glass panel through the pot support and the overflow tray, and heat radiation mainly radiates the combustion flame and high-temperature smoke to the tempered glass panel. The conductive heat dissipation part is made of high thermal conductivity material. The high thermal conductivity material is set on the back of the tempered glass panel to quickly absorb the high-temperature heat of the tempered glass panel and can quickly dissipate the heat. The reflective insulation part is made of low thermal conductivity material and is set on the front of the glass to reduce the absorption of radiation waves, increase the reflection of radiation waves, and thus reduce the absorption of radiant heat from the burner. Reduce the heat conduction and heat transfer of the tempered glass panel to achieve a cooling effect, thereby reducing the overall temperature difference of the tempered glass panel, avoiding thermal explosions, and being safer.

[0029] The positive progressive effect of the utility model is that the utility model discloses a stove table and a stove including the same. The heat source of the tempered glass panel of the stove is the combustion of the burner, which is mainly divided into two heat transfer modes, heat conduction and heat radiation. Heat conduction mainly transfers heat to the tempered glass panel through the pot support and the overflow tray, and heat radiation mainly radiates the combustion flame and high-temperature smoke to the tempered glass panel. The conductive heat dissipation part is made of a material with a high thermal conductivity coefficient. The material with a high thermal conductivity coefficient is arranged on the back of the tempered glass panel, which can quickly absorb the high-temperature heat of the tempered glass panel and can quickly dissipate the heat. The reflective insulation part is made of a material with a low thermal conductivity coefficient and is arranged on the front of the glass to reduce the absorption of radiation waves, increase the reflection of radiation waves, and thus reduce the absorption of the radiant heat of the burner.

[0054] The following is a preferred embodiment, and the present invention is described more clearly and completely in conjunction with the accompanying drawings. Figure 1 As shown, this embodiment provides a stove, which includes a burner and a stove table 120. The stove table 120 is made of a tempered glass panel, and the burner head 1 of the stove burner is arranged on the tempered glass panel. The stove table 120 can prevent the tempered glass from thermal explosion. A heat dissipation component is designed on the back of the high temperature area of ​​the glass panel. The heat dissipation component can prevent the glass from thermal explosion and prevent the glass from splashing when it explodes due to other reasons, thereby threatening the user's life safety.

[0055] like Figures 2 to 4 As shown, the stove top 120 of this embodiment includes a tempered glass panel, which includes a conductive heat dissipation portion 140 and a reflective heat insulation portion 130. The conductive heat dissipation portion 140 is arranged on a side of the tempered glass panel facing the inside of the stove and can conduct heat; the reflective heat insulation portion 130 is arranged on a side of the tempered glass panel facing the outside of the stove and can reflect and isolate heat radiation.

[0056] In this embodiment, the conductive heat dissipation part 140 and the reflective heat insulation part 130 are respectively arranged on the front and back sides of the tempered glass panel. The heat source of the tempered glass panel of the stove is the combustion of the burner, which is mainly divided into two heat transfer modes, heat conduction and heat radiation. Heat conduction is mainly through the pot support and the overflow pan 3 to transfer heat to the tempered glass panel, and heat radiation is mainly the combustion flame and high-temperature flue gas radiated to the tempered glass panel. The conductive heat dissipation part 140 is made of a material with a high thermal conductivity coefficient. The material with a high thermal conductivity coefficient is arranged on the back of the tempered glass panel to quickly absorb the high-temperature heat of the tempered glass panel and can quickly dissipate the heat. The reflective heat insulation part 130 is made of a material with a low thermal conductivity coefficient. It is arranged on the front side of the glass to reduce the absorption of radiation waves, increase the reflection of radiation waves, and thus reduce the absorption of the radiant heat of the burner. Reduce the heat conduction and heat transfer of the tempered glass panel to achieve a cooling effect, thereby reducing the overall temperature difference of the tempered glass panel, avoiding thermal explosion, and being safer.

[0057] In this embodiment, the conductive heat dissipation part 140 is black, and the reflective heat insulation part 130 is white. The same color has different abilities to absorb electromagnetic radiation. White absorbs heat slowly and dissipates heat slowly, while black is the opposite. Placing black high thermal conductivity material on the back of the glass for heat dissipation can accelerate the cooling of the high temperature area of ​​the glass. Placing white low thermal conductivity material on the front of the glass can reduce the absorption of radiation waves, increase the reflection of radiation waves, and thus reduce the absorption of the radiant heat of the burner.

[0058] In other embodiments, the conductive heat dissipation portion 140 and the reflective heat insulation portion 130 may also be set to other corresponding dark and light colors. At the same time, only one side thereof may be set to a corresponding color.

[0059] In this embodiment, the side of the reflective insulation part facing the outside of the cooker is a mirror surface. The mirror surface low thermal conductivity material is arranged on the front side of the glass to further reduce the absorption of radiation waves, increase the reflection of radiation waves, and thus reduce the absorption of the radiant heat of the burner.

[0060] In other embodiments, other materials with high reflectivity such as metal materials may also be used.

[0061] In this embodiment, the thickness of the reflective heat insulation part 130 is greater than the thickness of the conductive heat dissipation part 140. The thermal conductivity is inversely related to the material thickness, which means that when the material thickness increases, its thermal conductivity decreases. Reasonable thickness is one of the factors for controlling temperature. A relatively thin material can be selected for the back heat dissipation material, which can be more conducive to the conductive heat dissipation part 140 absorbing heat and dissipating heat through conduction. A relatively thick material is selected for the front side, which can be more conducive to the reflective heat insulation part 130 isolating heat radiation and reducing heat absorption.

[0062] like Figure 3 , Figure 6 As shown, the stove table 120 also includes an air barrier 110, which is arranged between the stove burner 1 and the tempered glass panel. In this embodiment, the air barrier 110 is a cavity relatively sealed from the outside world, filled with air, and uses the low thermal conductivity of air to block heat. Being arranged between the stove burner 1 and the tempered glass panel can slow down the heat transfer between the stove burner 1 and the tempered glass panel, and reduce the heat absorption of the tempered glass panel.

[0063] like Figure 6 As shown, the stove table 120 also includes an overflow pan 3 arranged around the stove head 1, the edge of the overflow pan 3 protrudes upward to form a protrusion 31, and the air barrier 110 is formed in the cavity between the protrusion 31 of the overflow pan 3 and the tempered glass panel. The air barrier 110 is arranged in the protrusion of the overflow pan 3, and the overflow pan 3 itself needs to be arranged around the stove head 1 and has a certain protrusion to form the protrusion 31. The air barrier 110 is arranged in the space inside the protrusion 31, which can better isolate the stove head 1 and the tempered glass panel, and at the same time, the space utilization rate is higher.

[0064] like Figure 7As shown, the stove table 120 also includes a partition frame 111, and the partition frame 111 includes a frame body and a plurality of baffles 112. The frame body covers the tempered glass panel, and the plurality of baffles are sealed and connected to the top surface and / or the side surface of the tempered glass panel. Two adjacent baffles 112, the frame body, and the tempered glass panel define an air barrier 110. The air barrier 110 is formed by the partition frame 111. The frame body of the partition frame 111 covers the tempered glass panel, and the frame body has a plurality of baffles 112. After the baffles 112 are pressed against the tempered glass panel, the space between the tempered glass panel, the baffles 112, and the frame body forms a closed enclosed space, thereby forming the air barrier 110. According to the different sealing positions of the baffles 112 and the tempered glass panel, the air barrier 110 can be formed on the top surface or the side surface of the tempered glass panel, and the heat transfer can be reduced in both the height direction and the horizontal direction.

[0065] like Figure 8 As shown, a through slot 121 is provided on the tempered glass panel, the stove head 1 of the cooker is arranged in the through slot 121, and the spacer 111 covers the edge of the through slot 121. The opening of the tempered glass panel stove head 1 can avoid the high temperature area, and the size of the opening and the front heat insulation component cooperate with each other to achieve the minimum heat absorption within the coverage range of the liquid tray. The spacer 111 is arranged at the edge of the through slot 121, which can reduce heat transfer in both the height direction and the horizontal direction.

[0066] In this embodiment, the through slot 121, the overflow tray 3 and the partition frame 111 are all squares with matching shapes. The three are stacked and matched with each other. The overflow tray 3 and the partition frame 111 cover the through slot 121 and isolate the furnace head 1 and the tempered glass partition.

[0067] like Figure 5 , Fig. 9 , Fig.10 and Fig.11 As shown, the area of ​​the stove table 120 close to the ejector tube 11 of the stove is a high-heat area 122, and the area of ​​the stove table 120 far from the ejector tube 11 is a low-heat area. The conductive heat dissipation part 140 and the reflective heat insulation part 130 at least cover the high-heat area 122. In this embodiment, when the gas stove is burning normally, the temperature area of ​​the glass panel shows a trend of gradually decreasing with the burner as the center, and changes with the distribution of the burner ejector tube 11 and the flow channel structure of the ignition distributor. The temperature near the exit of the ejector tube 11 is in the higher temperature area of ​​the entire panel. If the highest temperature of this area can be reduced, the temperature rise of the entire panel can be reduced and the temperature difference of the panel can be reduced. Targetedly arranging the conductive heat dissipation part 140 and the reflective heat insulation part 130 in these high-heat areas 122 has a better heat dissipation effect and reduces the overall temperature difference of the glass panel. Fig.11In the embodiment, the heat map calculation can further verify the position of the high-heat area 122. In this embodiment, the back of the glass needs to be provided with the conduction heat dissipation part 140 in the whole area, and the conduction heat dissipation part 140 is preferably connected by gluing, which can prevent the glass from thermal explosion and splashing when the glass explodes due to other reasons, thereby threatening the user's life safety.
