[0045] Embodiment one

[0046] The embodiment provides a gas stove, as shown in the figure, the gas stove comprises a support 70, a panel assembly 10, a burner 40 and a gas supply assembly, wherein the panel assembly 10 covers the upper side of the support 70, for improving the aesthetic degree of the gas stove. The burner 40 and the gas supply assembly are both installed on the support 70, and the panel assembly 10 is provided with a relief hole 13, which is used for avoiding the installation of the burner 40, so that the burner 40 is at least partially exposed on the upper side of the panel assembly 10. The gas supply assembly is used for providing gas for the burner 40, and the burner 40 burns the gas to generate a flame. Figures 1-3 The embodiment provides a gas stove, as shown in the figure, the gas stove comprises a support 70, a panel assembly 10, a burner 40 and a gas supply assembly, wherein the panel assembly 10 covers the upper side of the support 70, for improving the aesthetic degree of the gas stove. The burner 40 and the gas supply assembly are both installed on the support 70, and the panel assembly 10 is provided with a relief hole 13, which is used for avoiding the installation of the burner 40, so that the burner 40 is at least partially exposed on the upper side of the panel assembly 10. The gas supply assembly is used for providing gas for the burner 40, and the burner 40 burns the gas to generate a flame.

[0047] As Figure 1 shown, the gas stove further comprises a water receiving tray 60, which is arranged on the upper side of the panel assembly 10 and surrounds the outer periphery of the burner 40, and can block the avoiding hole 13. The water receiving tray 60 is used to receive the overflow liquid generated during the cooking process, so as to avoid the overflow liquid flowing into the gas stove. The gas stove further comprises a pot rack 50, which is supported on the water receiving tray 60 and surrounds the outer periphery of the burner 40, and is used to support the pot.

[0048] Optionally, in the embodiment, the gas stove comprises two burners 40, so that two avoiding holes 13 are arranged on the panel assembly 10 correspondingly, and the water receiving tray 60 and the pot rack 50 are arranged correspondingly at each burner 40. In other embodiments, the specific number of burners 40 can also be one, three or more, which will not be described here.

[0049] For the purpose of aesthetics and easy cleaning, the panel of the existing gas stove uses a glass panel. However, during the working process of the burner, the glass panel will absorb the heat released from the burner, so that the temperature of the area close to the burner of the glass panel is relatively high, and the temperature of the area far away from the burner is relatively low, the temperature distribution of the whole glass panel is uneven, which can easily cause the glass to break. In the related art, in order to prevent the glass panel from splashing after breaking, the current method is to stick a blast-proof film on the back of the panel. However, although the blast-proof film can prevent splashing when the glass panel breaks, it hinders the heat dissipation of the glass panel, which increases the risk of thermal cracking of the glass panel.

[0050] To this end, as Figures 2-3 shown, the panel assembly 10 comprises a glass panel 11 and a blast-proof layer 12, the lower side of the glass panel 11 is provided with a cooling groove 111 around the avoiding hole 13, and the blast-proof layer 12 is arranged on the lower side of the glass panel 11 and surrounds the cooling groove 111 to form a cooling channel 14. The gas stove further comprises a liquid supply assembly 20, which is in communication with the cooling channel 14 and can introduce cooling medium into the cooling channel 14.

[0051] When the burner 40 is working, the liquid supply assembly 20 supplies cooling medium into the cooling channel 14, thereby cooling the area of the panel assembly 10 around the escape hole 13, avoiding excessive temperature difference between the area of the glass panel 11 close to the burner 40 and the area far from the burner 40, thereby reducing the risk of glass panel 11 cracking and improving the service life of the gas stove. The cooling channel 14 is directly formed between the glass panel 11 and the explosion-proof layer 12, without the need for additional piping, and does not increase the thickness of the panel assembly 10, thereby facilitating the lightweight design of the gas stove. In addition, once the glass panel 11 cracks in extreme cases, the explosion-proof layer 12 can prevent the fragments from splashing, ensuring the safety of the user. It can be understood that the specific material of the explosion-proof layer 12 can be any one of the prior art without departing from the inventive concept of the present application, which is not limited here. Alternatively, the explosion-proof layer 12 is connected to the lower side of the glass panel 11 by pasting.

[0052] As shown in Figure 4 The liquid supply assembly 20 includes a cooling medium container 21 for storing cooling medium, and a drive pump 24. The inlet and outlet of the cooling channel 14 are in communication with the cooling medium container 21, thereby forming a circulating loop between the cooling channel 14 and the cooling medium container 21, and the drive pump 24 can drive the cooling medium to circulate between the cooling medium container 21 and the cooling channel 14. Specifically, the cooling medium container 21 is connected to the liquid outlet main pipe 23 and the liquid inlet main pipe 22 at both ends, respectively. The inlet end of the cooling channel 14 is in communication with the liquid outlet main pipe 23, and the outlet end of the cooling channel 14 is in communication with the liquid inlet main pipe 22. The drive pump 24 can be provided on the liquid inlet main pipe 22 or the liquid outlet main pipe 23. In the present embodiment, the cooling medium is water, which has good cooling effect and low cost. In other embodiments, the cooling medium can also be oil, which is not limited here.

[0053] For gas cooktops with two or more burners 40, the cooling channels 14 surrounding each burner 40 can be supplied with liquid via a single liquid supply assembly 20. Optionally, in some embodiments, each cooling channel 14 is connected to a liquid inlet manifold 22 and a liquid outlet manifold 23 via connecting pipes at both ends. The drive pump 24 can be located on either the liquid inlet manifold 22 or the liquid outlet manifold 23, allowing a single drive pump 24 to simultaneously supply cooling medium to the cooling channels 14 located at each burner 40. In this embodiment, the connecting pipes connecting each cooling channel 14 can be provided with a shutoff valve. By opening different shutoff valves, cooling medium can be selectively supplied to different cooling channels 14. In other embodiments, the liquid supply assembly 20 includes multiple sets of liquid inlet manifolds 22, liquid outlet manifolds 23, and drive pumps 24. Each cooling channel 14 located at each burner 40 is connected to a corresponding set of liquid inlet manifolds 22 and liquid outlet manifolds 23. Each drive pump 24 corresponds to a cooling channel 14 and is used to supply cooling medium to the corresponding cooling channel 14.

[0054] like Figure 4 As shown, the cooling channel 14 is spirally constructed and is concentrically arranged with the avoidance hole 13. The spiral cooling channel 14 can fully and evenly cool the area around the avoidance hole 13, thereby better preventing the glass panel 11 from breaking due to excessive temperature difference.

[0055] In this embodiment, the innermost end of the cooling channel 14 serves as the inlet, while the outermost end of the cooling channel 14 serves as the outlet. Specifically, the liquid outlet manifold 23 is connected to the innermost end of the cooling channel 14, and the liquid inlet manifold 22 is connected to the outermost end of the cooling channel 14. The cooling medium flows from the innermost to the outermost ring of the cooling channel 14. It is understood that as the cooling medium flows through the cooling channel 14, its temperature gradually increases, resulting in a decreasing cooling capacity. During operation of the burner 40, locations radially closer to the center of the avoidance hole 13 experience higher temperatures and greater cooling requirements. In this embodiment, the cooling medium flows from the innermost to the outermost ring of the cooling channel 14, thereby matching its cooling capacity with the cooling requirements of the locations it flows to. This ensures a relatively uniform cooling rate at all radial locations around the avoidance hole 13, thereby better preventing the glass panel 11 from shattering due to excessive temperature differences.

[0056] Of course, in some embodiments, the end of the outermost circle of the cooling channel 14 may be selected as the inlet of the cooling channel 14 , and the end of the innermost circle of the cooling channel 14 may be selected as the outlet of the cooling channel 14 .

[0057] In some embodiments, such as Figure 5As shown, the cross-sectional area of ​​the cooling channel 14 gradually decreases from the innermost circle to the outermost circle. It is understood that locations with larger cross-sectional areas in the cooling channel 14 have larger heat exchange areas with the glass panel 11, and the cooling medium flows slower in these locations, resulting in more efficient heat exchange and higher cooling capacity. By gradually reducing the cross-sectional area of ​​the cooling channel 14 from the inside out, the cooling capacity of each location of the cooling channel 14 is matched to the cooling requirements of the glass panel 11 at the corresponding location, ensuring a relatively uniform cooling rate of the glass panel 11 in the area surrounding the avoidance hole 13, thereby more reliably preventing the glass panel 11 from shattering due to temperature differences.

[0058] In some embodiments, such as Figure 6 As shown, the distance between adjacent circles of cooling channels 14 gradually increases radially from the inside to the outside of the avoidance hole 13. In other words, the density of cooling channels 14 increases radially and toward the burner 40, thereby increasing the corresponding cooling capacity. This arrangement matches the cooling capacity of the cooling channels 14 with the cooling requirements of the glass panel 11 at the corresponding location, ensuring a relatively uniform cooling rate across the glass panel 11 around the avoidance hole 13, thereby more reliably preventing the glass panel 11 from shattering due to large temperature differences.

[0059] like Figure 4 As shown, the gas cooker further includes a temperature detection assembly 30, which is used to detect the temperature of the panel assembly 10. The temperature detection assembly 30 is communicatively connected to the liquid supply assembly 20. Specifically, the temperature detection assembly 30 is electrically connected to the drive pump 24 and is used to monitor the temperature of the panel assembly 10 in real time. When the temperature detection assembly 30 detects that the temperature is greater than or equal to a preset value, it indicates that the current glass panel 11 is at risk of shattering and needs to be cooled. At this time, the temperature detection assembly 30 sends a signal to the drive pump 24 through the gas cooker's control component. The drive pump 24 operates to circulate the cooling medium, thereby cooling the glass panel 11. When the temperature detection assembly 30 detects that the temperature is less than the preset value, it indicates that the glass panel 11 no longer needs to be cooled. At this time, the temperature detection assembly 30 sends a signal to the drive pump 24 through the gas cooker's control component to stop the circulation of the cooling medium.

[0060] In the embodiment, the temperature detection assembly 30 is arranged at a position close to the avoiding hole 13, and the temperature at the position close to the avoiding hole 13 reaches the preset temperature first. By arranging the temperature detection assembly 30 at the position, the signal that the glass panel 11 needs to be cooled can be obtained more quickly, and the reliability of cooling the glass panel 11 is ensured. It should be noted that for the gas stove with two or more burners 40, the temperature detection assembly 30 is arranged at each avoiding hole 13, and the liquid supply assembly 20 can perform targeted cooling on the panel assembly 10 according to the detection results of the temperature detection assemblies 30.

[0061] Embodiment Two

[0062] The embodiment provides a gas stove, which has the same general structure as that of the first embodiment, and the main difference is the arrangement of the cooling channel 14, which is as follows.

[0063] As shown in Figure 7 each cooling channel 14 includes a plurality of sub-channels 141, each of which is in communication with the liquid supply assembly 20, and the plurality of sub-channels 141 are concentrically arranged with the avoiding hole 13. When the liquid supply assembly 20 simultaneously supplies the cooling medium to each sub-channel 141, the area of the glass panel 11 close to the burner 40 can be rapidly and effectively cooled, and the risk of the glass panel 11 being broken can be reduced, and the service life of the gas stove can be prolonged.

[0064] In the embodiment, the liquid supply assembly 20 also includes the cooling medium container 21 and the driving pump 24, and the inlet and outlet of each sub-channel 141 are in communication with the cooling medium container 21, so that a circulating loop is formed between each sub-channel 141 and the cooling medium container 21. The driving pump 24 can drive the cooling medium to circulate between each sub-channel 141 and the cooling medium container 21.

[0065] Optionally, in the embodiment, the cooling medium container 21 is connected with the liquid outlet main pipe 23 and the liquid inlet main pipe 22 at two ends, respectively, the inlet end of each sub-channel 141 is in communication with the liquid outlet main pipe 23 through a liquid outlet connecting pipe 26, and the outlet end of each sub-channel 141 is in communication with the liquid inlet main pipe 22 through a liquid inlet connecting pipe 27. The driving pump 24 can be arranged on the liquid inlet main pipe 22 or the liquid outlet main pipe 23, so that the cooling medium can be driven to flow in each sub-channel 141. Optionally, in some embodiments, a part of the liquid inlet connecting pipe 27 / liquid outlet connecting pipe 26 is formed by a groove arranged on the glass panel and the explosion-proof layer 12, and a part is formed by a pipe arranged outside the panel assembly 10. In some embodiments, the liquid inlet connecting pipe 27 and the liquid outlet connecting pipe 26 are entirely composed of pipes arranged outside the panel assembly 10.

[0066] In some embodiments, the liquid supply assembly 20 comprises a cooling medium container 21 and a plurality of driving pumps 24, each of the cooling channels 14 surrounding the burners 40 is in communication with the cooling medium container 21, and each of the driving pumps 24 is configured to supply liquid to one of the cooling channels 14.

[0067] In some embodiments, as shown in Figure 7 and Figure 8 , the liquid supply assembly 20 further comprises a stop valve 25, which is configured to synchronously open and close a plurality of sub-channels 141 of the same cooling channel 14. The control component (not shown in the figure) of the gas stove can drive the stop valve 25 to open before driving the driving pump 24 to open, and control the stop valve 25 to close after driving the driving pump 24 to close. The stop valve 25 can avoid the cooling medium from flowing unnecessarily, and the plurality of sub-channels 141 share one stop valve 25, so that the plurality of sub-channels 141 around the avoiding hole 13 can start cooling at the same time, which is high in cooling efficiency and convenient to control. Alternatively, the stop valve 25 can be a solenoid valve.

[0068] In order to ensure that the driving pump 24 and the stop valve 25 are opened and closed at the appropriate time, as shown in Figure 7 and Figure 8 , the gas stove further comprises a temperature detection assembly 30, which is electrically connected to the stop valve 25 and the driving pump 24 respectively. The temperature detection assembly 30 is configured to monitor the temperature of the panel assembly 10 in real time. When the temperature detection assembly 30 detects that the temperature is greater than or equal to a preset value, it indicates that the current glass panel 11 is at risk of breaking and needs to be cooled down. At this time, the temperature detection assembly 30 sends a signal to the driving pump 24 and the stop valve 25 respectively through the control component of the gas stove to start the circulation of the cooling medium. When the temperature detection assembly 30 detects that the temperature is less than the preset value, it indicates that the glass panel 11 no longer needs to be cooled down. At this time, the temperature detection assembly 30 sends a signal to the driving pump 24 and the stop valve 25 respectively through the control component of the gas stove to stop the circulation of the cooling medium. For the gas stove with a plurality of burners 40, one temperature detection assembly 30 is arranged at each avoiding hole 13, and the liquid supply assembly 20 can cool the panel assembly 10 according to the detection results of the temperature detection assemblies 30.

[0069] In this embodiment, the temperature detection assembly 30 can be a temperature sensor 31, which is arranged at the innermost sub-channel 141. The innermost sub-channel 141 is closest to the burner 40, so the temperature reaches the preset temperature first. By arranging the temperature detection assembly 30 at this position, the signal that the glass panel 11 needs to be cooled down can be obtained more quickly, ensuring the reliability of cooling the glass panel 11.

[0070] In some embodiments, as shown in Figure 9 and Figure 10 , the liquid supply assembly 20 further comprises a plurality of temperature detection assemblies 30, each of which is arranged at one of the avoiding holes 13.As shown, the liquid supply assembly 20 includes a plurality of shut-off valves 25, each of which is configured to open and close a sub-channel 141. The control component of the gas stove can open the corresponding shut-off valve 25 according to actual needs, thereby making the temperature reduction control of the panel assembly 10 more flexible. In this embodiment, each shut-off valve 25 can be connected to the corresponding liquid inlet connecting pipe 27 or the corresponding liquid outlet connecting pipe 26. Alternatively, the shut-off valve 25 can be a solenoid valve.

[0071] In order to facilitate the control component to control each shut-off valve 25 according to the actual temperature reduction needs of the glass panel 11, as shown in Figure 8 and Figure 9 As shown, the temperature detection assembly 30 includes a plurality of temperature sensors 31, each of which is arranged at a sub-channel 141, and each temperature sensor 31 is electrically connected to the drive pump 24 and the corresponding shut-off valve 25. Each temperature sensor 31 can monitor the temperature of the glass panel 11 at the corresponding position in real time. When the temperature sensor 31 detects that the temperature is greater than or equal to a preset value, it indicates that the glass panel 11 in the area where the temperature sensor 31 is located needs to be cooled down. At this time, the temperature sensor 31 sends a signal to the drive pump 24 and the corresponding shut-off valve 25 through the control component, the corresponding shut-off valve 25 is opened, and the corresponding sub-channel 141 starts circulating the cooling medium. Through the cooperation of the plurality of temperature sensors 31 and the plurality of shut-off valves 25, the flow of the cooling medium can be accurately controlled according to the actual temperature state of the glass panel 11 at each position, thereby making the temperature reduction of the panel assembly 10 more accurate and reducing energy consumption.

[0072] It can be understood that the closer to the position of the burner 40 along the radial direction of the avoidance hole 13 on the panel assembly 10, the higher the temperature and the greater the temperature reduction needs, while the farther away from the position of the burner 40, the lower the temperature and the smaller the temperature reduction needs, that is, the heat dissipation needs around the avoidance hole 13 are not consistent.

[0073] To this end, in some embodiments, as shown in Figure 7 and Figure 9 As shown, the distance between the adjacent two sub-channels 141 gradually increases along the radial direction of the avoidance hole 13 and in the direction from inside to outside, that is, the arrangement density of the sub-channels 141 gradually increases along the direction close to the burner 40. The higher the density of the sub-channels 141, the stronger the temperature reduction capacity of the glass panel 11. By setting the arrangement density of the sub-channels 141, the cooling capacity of the cooling channel 14 can be matched with the temperature reduction needs of the glass panel 11 at the corresponding position, thereby ensuring that the overall temperature reduction rate of the glass panel 11 around the avoidance hole 13 is relatively uniform, and thus more reliably preventing the glass panel 11 from being broken due to large temperature difference.

[0074] In some other embodiments, as shown in Figure 8 andFigure 10 As shown, the cross-sectional area of each sub-channel 141 gradually decreases in the radial direction of the avoidance hole 13 and from the inside to the outside. The greater the cross-sectional area of the sub-channel 141, the greater the heat exchange area between the sub-channel 141 and the glass panel 11, and the greater the cooling capacity of the sub-channel 141. By setting the gradient of the cross-sectional area of the sub-channel 141, the cooling capacity of each sub-channel 141 is matched with the cooling demand of the glass panel 11 at the corresponding position, ensuring that the cooling rate of the glass panel 11 in the area around the avoidance hole 13 is relatively uniform, thereby more reliably preventing the glass panel 11 from breaking due to temperature difference.

[0075] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, according to the idea of the present application, the specific embodiments and application scope can be changed, and the content of the specification should not be understood as limiting the present application.
