The burner 40 and the gas supply assembly are both mounted on the support 70, the panel assembly 10 is provided with a relief hole 13, the relief hole 13 is used for avoiding installation of the burner 40, and the burner 40 is at least partially exposed on the upper side of the panel assembly 10. The gas supply assembly is used for supplying gas to the burner 40, and the burner 40 burns the gas to generate a flame.

[0040] As shown in the drawings, Figure 1 The gas stove further comprises a water pan 60, the water pan 60 is arranged on the upper side of the panel assembly 10 and surrounds the outer periphery of the burner 40, and the water pan 60 can block the relief hole 13. The water pan 60 is used for receiving overflow liquid generated in a cooking process, so as to avoid the overflow liquid flowing into the gas stove. The gas stove further comprises a pot rack 50, the pot rack 50 is supported on the water pan 60 and surrounds the outer periphery of the burner 40, and the pot rack 50 is used for supporting a pot.

[0041] Optionally, in the embodiment, the gas stove comprises two burners 40, so that two relief holes 13 are correspondingly arranged on the panel assembly 10, and the water pan 60 and the pot rack 50 are correspondingly arranged 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.

[0042] 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 absorbs the heat released from the burner, so that the temperature of the area close to the burner is higher, and the temperature of the area far from the burner is lower, the temperature distribution of the whole glass panel is uneven, which is easy to cause the glass to break.

[0043] To this end, as Figures 1-3 shown, the panel assembly 10 is provided with a plurality of cooling channels 14 corresponding to each of the escape holes 13. Specifically, the plurality of cooling channels 14 are arranged concentrically around the outer periphery of the escape hole 13, and the gas stove further comprises a liquid supply assembly 20 which is in communication with the cooling channels 14 and can introduce cooling medium into each cooling channel 14. During the working process of the burner 40, the part of the panel assembly 10 located around the burner 40 absorbs the heat generated by the burner 40 and the temperature rises, at this time the liquid supply assembly 20 introduces cooling medium into the cooling channel 14, the plurality of concentrically arranged cooling channels 14 make the area of the glass panel 11 close to the burner 40 rapidly and effectively cool down as a whole, avoiding the generation of excessive temperature difference between the area close to the burner 40 and the area far from the burner 40 of the glass panel 11, thereby reducing the risk of glass panel 11 breaking and improving the service life of the gas stove.

[0044] As Figure 2 shown, in the present embodiment, the panel assembly 10 comprises a glass panel 11 and an explosion-proof layer 12, wherein the explosion-proof layer 12 is attached to the lower side of the glass panel 11, and once the glass panel 11 breaks in an extreme case, the explosion-proof layer 12 can avoid the splashing of fragments and ensure 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 existing technologies 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.

[0045] In the present embodiment, the lower side of the glass panel 11 is provided with a cooling groove, and the explosion-proof layer 12 is formed between the cooling groove after being bonded to the lower side of the glass panel 11 to form a cooling channel 14. Such arrangement does not require additional piping, thereby not increasing the thickness of the panel assembly 10, which is beneficial to the lightweight design of the gas stove. In other embodiments, the cooling channel 14 can also be composed of a pipe embedded in the panel assembly 10, which is not limited here.

[0046] As Figure 3As shown, the liquid supply assembly 20 comprises a cooling medium container 21 for storing cooling medium, and a driving pump 24. The inlet and outlet of each cooling channel 14 are communicated with the cooling medium container 21, so that a circulating loop is formed between each cooling channel 14 and the cooling medium container 21. The driving pump 24 can drive the cooling medium to circulate between the cooling medium container 21 and the cooling channels 14. In this 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.

[0047] Optionally, in this embodiment, each cooling channel 14 around the avoiding hole 13 is supplied with liquid by one liquid supply assembly 20. Specifically, the cooling medium container 21 is connected with an outlet main pipe 23 and an inlet main pipe 22 at two ends respectively, the inlet end of each cooling channel 14 is communicated with the outlet main pipe 23 through an outlet connecting pipe 26, and the outlet end of each cooling channel 14 is communicated with the inlet main pipe 22 through an inlet connecting pipe 27. The driving pump 24 can be arranged on the inlet main pipe 22 or the outlet main pipe 23. Optionally, in some embodiments, a part of the inlet connecting pipe 27 / outlet connecting pipe 26 is formed by the groove opened on the glass panel 11 and the explosion-proof layer 12, and a part is formed by the pipe outside the panel assembly 10. In some embodiments, the inlet connecting pipe 27 and the outlet connecting pipe 26 are all composed of the pipe outside the panel assembly 10.

[0048] In some embodiments, the liquid supply assembly 20 comprises one cooling medium container 21 and multiple driving pumps 24, and the multiple cooling channels 14 around each avoiding hole 13 are communicated with the cooling medium container 21, and each driving pump 24 is used to supply liquid to the multiple cooling channels 14 around the same avoiding hole 13.

[0049] In some embodiments, as shown in Figure 3 and Figure 4 , the liquid supply assembly 20 further comprises a stop valve 25, which is configured to synchronously open and close the multiple cooling channels 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 randomly when it is unnecessary, and the multiple cooling channels 14 share one stop valve 25, so that the multiple cooling channels 14 around the avoiding hole 13 can start cooling at the same time, which has high cooling efficiency and is convenient to control. Optionally, the stop valve 25 can be an electromagnetic valve.

[0050] 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 3 and Figure 4As shown, the gas stove further comprises a temperature sensor 30, which is electrically connected with the cut-off valve 25 and the driving pump 24 respectively. The temperature sensor 30 is used to monitor the temperature of the panel assembly 10 in real time. When the temperature sensor 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 being broken and needs to be cooled down. At this time, the temperature sensor 30 sends a signal to the driving pump 24 and the cut-off valve 25 respectively through the control component of the gas stove to start the circulation of the cooling medium. When the temperature sensor 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 sensor 30 sends a signal to the driving pump 24 and the cut-off valve 25 respectively through the control component of the gas stove to stop the circulation of the cooling medium.

[0051] In this embodiment, the temperature sensor 30 is arranged at the innermost cooling channel 14, which is closest to the burner 40 and thus the temperature reaches the preset temperature first. By arranging the temperature sensor 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 the cooling of the glass panel 11.

[0052] In some embodiments, as shown in Figure 5 and Figure 6 The liquid supply assembly 20 comprises a plurality of cut-off valves 25, each of which is configured to open and close one cooling channel 14. The control component of the gas stove can open the corresponding cut-off valve 25 according to the actual needs, thereby making the cooling control of the panel assembly 10 more flexible. In this embodiment, each cut-off valve 25 can be connected to the corresponding liquid inlet connection pipe 27 or the corresponding liquid outlet connection pipe 26. Alternatively, the cut-off valve 25 can be a solenoid valve.

[0053] In order to facilitate the control component to control each cut-off valve 25 according to the actual cooling needs of the glass panel 11, as shown in Figure 5 and Figure 6 The gas stove comprises a plurality of temperature sensors 30, each of which is arranged at one cooling channel 14 and is electrically connected with the driving pump 24 and the corresponding cut-off valve 25 respectively. Each temperature sensor 30 can monitor the temperature of the glass panel 11 at the corresponding position in real time. When the temperature sensor 30 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 30 is located needs to be cooled down. At this time, the temperature sensor 30 sends a signal to the driving pump 24 and the corresponding cut-off valve 25 respectively through the control component, the corresponding cut-off valve 25 is opened, and the corresponding cooling channel 14 starts the circulation of the cooling liquid. Through the cooperation of the plurality of temperature sensors 30 and the plurality of cut-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 cooling of the panel assembly 10 more accurate and facilitating the reduction of energy consumption.

[0054] 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 cooling demand, while the farther away from the position of the burner 40, the lower the temperature, and the relatively smaller the cooling demand, that is, the heat dissipation demand of the area around the avoidance hole 13 is not uniform.

[0055] For this purpose, in some embodiments, as shown in Figure 3 and Figure 5 , the distance between the adjacent two cooling channels 14 gradually increases along the radial direction of the avoidance hole 13 and from the inside to the outside, that is, the arrangement density of the cooling channels 14 gradually increases along the direction close to the burner 40. The higher the density of the cooling channels 14, the greater the cooling capacity of the cooling channels 14 to the glass panel 11. By setting the arrangement density of the cooling channels 14, the cooling capacity of the cooling channels 14 is matched with the cooling demand of the glass panel 11 at the corresponding position, so as to ensure that the overall 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 being broken due to large temperature difference.

[0056] In some other embodiments, as shown in Figure 4 and Figure 6 , the cross-sectional area of each cooling channel 14 gradually decreases along the radial direction of the avoidance hole 13 and from the inside to the outside. The larger the cross-sectional area of the cooling channel 14, the larger the heat exchange area between the cooling channel 14 and the glass panel 11, and the greater the cooling capacity of the cooling channel 14. By setting the gradient of the cross-sectional area of the cooling channel 14, the cooling capacity of each cooling channel 14 is matched with the cooling demand of the glass panel 11 at the corresponding position, so as to ensure 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 being broken due to temperature difference.

[0057] 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 range can be changed, and the content of the specification should not be understood as limiting the present application.
