Description

Technical Field

[0001] This utility model relates to a liquid receiving tray device and a gas stove containing the same. Background Technology

[0002] The drip tray of a cooktop is fixedly installed on the glass panel, and is prevented from sliding by adhesive or a limiting structure. The drip tray's main function is to catch spilled liquid, preventing it from spreading over a large area and affecting surrounding cabinets and appliances. As cooktop loads increase, the radiant and conductive heat cannot be ignored, leading to increasingly higher temperatures transferred to the glass panel. Excessive panel temperature is a significant cause of spontaneous breakage. Current drip tray structures are simplistic; generally, increasing the tray's area reduces panel temperature. However, when external temperatures are too high, the drip tray's heat-blocking capacity is limited, increasing the risk of spontaneous breakage due to overheating; furthermore, it significantly increases costs.

Furthermore, the structure is simple and easy to manufacture.

[0054] Panel 20

[0055] Support foot 30 Detailed Implementation

[0056] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a gas stove, which includes a burner 10, a panel 20 and a liquid receiving tray device. The liquid receiving tray device is disposed on the panel 20, and the burner 10 is disposed in the liquid receiving tray device for combustion.

[0058] The liquid receiving tray device includes a liquid receiving tray body 1, with a central hole 11 in the middle through which a burner 10 can pass. The interior of the liquid receiving tray body 1 has at least one heat-insulating space 12. The burner 10 is located in the middle of the liquid receiving tray body 1 and is used for combustion. The liquid receiving tray body 1 is positioned between the burner 10 and the panel 20. The presence of at least one heat-insulating space 12 inside the liquid receiving tray body 1 enhances the heat insulation effect of the liquid receiving tray device, reduces outward heat transfer, allows the temperature to be transferred upward to the cookware, increases the heat exchange effect of the cookware, reduces the outward transmission of the flame, and reduces the heat radiation received by the panel 20, effectively avoiding the risk of spontaneous explosion caused by excessive heat in the panel 20.

[0059] Multiple secondary air inlets 13 are provided on the outer surface of the liquid receiving tray body 1, and multiple secondary space outlets 14 are provided on the inner wall surface of the liquid receiving tray body 1. Both the multiple secondary air inlets 13 and the multiple secondary space outlets 14 are connected to the heat insulation space 12, allowing external air to sequentially pass through the secondary air inlets 13, the heat insulation space 12, and the secondary space outlets 14. Secondary space outlets 14 and secondary air inlets 13 are respectively provided on the inner and outer sides of the liquid receiving tray body 1, allowing external air to flow sequentially through the secondary air inlets 13, the heat insulation space 12, and the secondary space outlets 14 into the middle area of ​​the liquid receiving tray body 1, where it is used for combustion in the burner 10. The secondary air is preheated as it passes through the heat insulation space 12, further improving the thermal efficiency of the gas stove.

[0060] In this embodiment, the liquid receiving tray body 1 includes a supporting base 15 and a partition 16. The partition 16 is located above the supporting base 15. The partition 16 includes a partition body 161, an outer ring edge 162, and an inner ring edge 163. One end of the outer ring edge 162 is connected to the outer edge of the partition 16, and the other end of the outer ring edge 162 is bent in the direction close to the supporting base 15. One end of the inner ring edge 163 is connected to the inner edge of the partition 16, and the other end of the inner ring edge 163 is bent in the direction close to the supporting base 15. Both the outer ring edge 162 and the inner ring edge 163 are connected to the top surface of the supporting base 15, so that a heat insulation space 12 is formed between the partition 16 and the top surface of the supporting base 15. The central hole 11 penetrates the supporting base 15 and the inner ring edge 163. Multiple secondary air inlets 13 are located on the outer ring edge 162, and multiple secondary space outlets 14 are located on the inner ring edge 163.

[0061] like Figures 1 to 5As shown, there is one partition layer 16, located above the supporting chassis 15. The partition layer 16 is set on the top surface of the supporting chassis 15 through the bent outer ring edge 162 and inner ring edge 163, so that a heat insulation space 12 is formed between the partition layer 16 and the top surface of the supporting chassis 15. The overall structure is simple. The secondary space outlet 14 and the secondary air inlet 13 are respectively opened on the outer ring edge 162 and the inner ring edge 163, which facilitates processing and manufacturing.

[0062] Of course, in other embodiments, there can be multiple partitions 16, which are stacked along the height direction, and a heat-insulating space 12 is formed between any two adjacent partitions 16. The lowest partition 16 is connected to the top surface of the supporting base 15. By forming multiple heat-insulating spaces 12 through multiple partitions 16, the heat insulation effect of the liquid receiving tray device is greatly improved, the outward heat transfer is reduced, the temperature is transferred upward to the cookware, the heat exchange effect of the cookware is increased, the flame is reduced to the outside, and the heat radiation received by the panel 20 is reduced, effectively avoiding the risk of spontaneous explosion caused by the panel 20 overheating.

[0063] The projected area of ​​the support base 15 in the vertical direction is larger than the projected area of ​​the partition 16, and the top surface of the support base 15 can be used to collect and contain spilled liquid. Liquid on the partition 16 can flow downward to the support base 15, and the top surface of the partition body 161 of the partition 16 can also be designed to collect and contain spilled liquid.

[0064] In this embodiment, the partition 16 is detachably connected to the support chassis 15. The overflowing liquid may flow into the heat insulation space 12 through the secondary space outlet 14 or the secondary air inlet 13. The detachable connection between the partition 16 and the support chassis 15 facilitates the cleaning of the liquid in the heat insulation space 12, making cleaning very convenient.

[0065] Specifically, the top surface of the support chassis 15 has a downwardly recessed outer mounting groove and an inner mounting groove, with the outer ring edge 162 and the inner ring edge 163 inserted into the outer mounting groove and the inner mounting groove, respectively. The partition 16 is inserted into the outer mounting groove and the inner mounting groove on the top surface of the support chassis 15 via the outer ring edge 162 and the inner ring edge 163, respectively, thus connecting the partition 16 to the support chassis 15. This effectively prevents the partition 16 from shifting or misaligning during use, ensuring high stability. Simultaneously, it achieves precise positioning and installation, making setup convenient.

[0066] Of course, in other embodiments, the partition 16 can also be fixedly connected to the support chassis 15. The partition 16 and the support chassis 15 are fixedly connected, which provides high connection strength and makes the liquid receiving tray device easy to install and disassemble. Specifically, the outer ring edge 162 and the inner ring edge 163 are both welded to the top surface of the support chassis 15, making installation and connection convenient.

[0067] The partition 16 has multiple support through holes 17 for the support legs 30 to pass through, and all the support through holes 17 are connected to the heat insulation space 12. The pot support includes multiple support legs 30, which are used to support the pot. The support legs 30 pass through the support through holes 17 and are inserted into the liquid receiving tray body 1, so that the multiple support legs 30 are installed and connected to the liquid receiving tray body 1, making the structural connection between the pot support and the liquid receiving tray body 1 stable and reliable, and increasing the stability of the pot support.

[0068] In this embodiment, the top surface of the support base 15 has multiple limiting portions 151, each corresponding to a plurality of support foot through holes 17. The limiting portions 151 are located directly below the corresponding support foot through hole 17, and each limiting portion 151 limits a plurality of support feet 30. The support feet 30 pass through the support foot through holes 17 from top to bottom and connect to the corresponding limiting portions 151. The limiting portions 151 further restrict the support feet 30, effectively preventing the pot support from shifting or misaligning during use, thus further improving the stability of the gas stove.

[0069] Specifically, the top surface of the support base 15 has an outwardly protruding boss, and a limiting part 151 is recessed downward from the top surface of the boss, into which the support leg 30 is inserted. The top surface of the support base 15 forms the boss and the limiting part 151 through an upwardly protruding and downwardly recessed structure. The support leg 30 is inserted into the recessed limiting part 151, and the two sides of the support leg 30 abut against the boss, so that the support leg 30 can only move up and down and will not deviate in other directions, ensuring the stability of the support leg 30 when supporting the pot. At the same time, the structure is simple and easy to manufacture. The top of the support leg 30 extends upward from the top surface of the partition body 161 and is used to support the pot, so that the top of the support leg 30 of the pot support directly contacts the flame, reducing the direct heat transfer of the pot support to the panel 20.

[0070] In this embodiment, the number of support through holes 17 is the same as the number of support feet 30. The support through holes 17 penetrate through the partition body 161 and the outer ring edge 162, facilitating the installation of the pot support and the observation of whether the pot support is installed in place. Of course, the support through holes 17 can also penetrate only through the partition body 161, or the support through holes 17 can penetrate through the partition body 161 and the inner ring edge 163.

[0071] The specific number of secondary air inlets 13 and secondary space outlets 14 is not limited. Multiple secondary air inlets 13 are evenly spaced on the outer side of the liquid receiving tray body 1, and multiple secondary space outlets 14 are evenly spaced on the inner side of the liquid receiving tray body 1. The multiple secondary air inlets 13 and multiple secondary space outlets 14 are staggered to enhance air preheating and further improve the thermal efficiency of the gas stove. The number of secondary space outlets 14 can be the same as the number of secondary air ports on the burner 10 and correspond to each other, allowing air flowing through the secondary space outlets 14 to the secondary air ports of the burner 10 for combustion in the inner ring burner cap.

[0072] The inner wall of the liquid receiving tray body 1 is provided with a fixed mounting portion 18 extending towards the center. The liquid receiving tray body 1 is fixedly connected via the fixed mounting portion 18, ensuring that the liquid receiving tray body 1 will not move during use and has high stability. Multiple fixed mounting portions 18 are evenly spaced within the support base 15. The support base 15 can be integrally formed with the multiple fixed mounting portions 18.

[0073] In this embodiment, the partition 16 is located above the supporting chassis 15. Of course, in other embodiments, the partition 16 may also be located below the supporting chassis 15. Specifically, the liquid receiving tray body 1 includes a supporting base 15 and a partition 16. The partition 16 is located below the supporting base 15. The partition 16 includes a partition body 161, an outer ring edge 162, and an inner ring edge 163. One end of the outer ring edge 162 is connected to the outer edge of the partition 16, and the other end of the outer ring edge 162 is bent in the direction close to the supporting base 15. One end of the inner ring edge 163 is connected to the inner edge of the partition 16, and the other end of the inner ring edge 163 is bent in the direction close to the supporting base 15. Both the outer ring edge 162 and the inner ring edge 163 are connected to the bottom surface of the supporting base 15, so that a heat insulation space 12 is formed between the partition 16 and the bottom surface of the supporting base 15. The central hole 11 penetrates the supporting base 15 and the inner ring edge 163. Multiple secondary air inlets 13 are located on the outer ring edge 162, and multiple secondary space outlets 14 are located on the inner ring edge 163. The top surface of the supporting base 15 can be used to collect and contain spilled liquid. The partition 16 is located below the supporting base 15 and utilizes the space below, making the structure more compact. The partition 16 can be one or multiple, stacked along the height direction to form multiple heat-insulating spaces 12. This greatly improves the heat insulation effect of the liquid-receiving tray device, reduces outward heat transfer, allows heat to be transferred upwards to the cookware, increases the heat exchange effect of the cookware, reduces the outward transmission of flame, and reduces heat radiation received by the panel 20, effectively avoiding the risk of spontaneous explosion due to excessively high panel 20 temperature.
