They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Some existing gas stoves include burners, liquid trays, glass panels and other components. The liquid tray is generally square and is arranged on the glass panel. During assembly, in order to prevent the liquid tray from tilting relative to the glass panel, a tool is required to fix the liquid tray and then install it on the glass panel. However, the use of tooling during the assembly process will reduce assembly efficiency, reduce the production efficiency of the gas stove, and increase the production cost of the gas stove.

[0037] In order to solve the above technical problems, the present embodiment provides a gas cooker, which is provided with matching positioning structures on the liquid collecting pan 2 and the burner 1, respectively, so that the liquid collecting pan 2 can be placed directly on the burner 1 in a fixed position, while also preventing the liquid collecting pan 2 from moving during the fixing process, causing the liquid collecting pan 2 to be installed crookedly.

[0038] like Figure 1 As shown, a gas stove provided in this embodiment includes a burner 1 , a liquid collecting pan 2 is sleeved on the outer peripheral side of the burner 1 , and a gas stove panel is arranged below the liquid collecting pan 2 .

[0039] The liquid collecting pan 2 is provided with a positioning portion 3 recessed downward, and the burner 1 is provided with a positioning groove 4 recessed downward; after the positioning portion 3 and the positioning groove 4 are provided, when the liquid collecting pan 2 is installed, the positioning portion 3 is inserted downward into the positioning groove 4 to position the liquid collecting pan 2 on the burner 1, and the liquid collecting pan 2 will not move during the subsequent fixing process, and there is no need to use tooling to fix the liquid collecting pan 2.

[0040] A through hole 5 is provided at the bottom of the positioning portion 3, and a fixing hole 6 extending downward is provided at the bottom of the positioning groove 4. The cross-sectional diameter of the positioning groove 4 in the horizontal direction is larger than the cross-sectional diameter of the fixing hole 6 in the horizontal direction. When fixing the liquid collecting pan 2, a connecting piece 7 is inserted into the fixing hole 6 through the through hole 5 to fix the liquid collecting pan 2 on the burner 1.

[0041] Preferably, the cross-sectional shape of the positioning portion 3 and the through hole 5 in the horizontal direction is circular, and the through hole 5 is arranged at the center position of the positioning portion 3; the cross-sectional shape of the positioning groove 4 and the fixing hole 6 in the horizontal direction is circular, and the fixing hole 6 is arranged at the center position of the positioning groove 4 and extends axially along the positioning groove 4.

[0042] Optionally, the connecting member 7 is a fastening screw or a latch. Figure 5 As shown, the gas cooker provided in this embodiment has a connecting member 7 which is a fastening screw, and a thread matching the fastening screw is arranged on the inner wall of the fixing hole 6; when the connecting member 7 is a latch member, an elastic fixing structure is arranged on the member body, and a hole for accommodating the elastic fixing structure is arranged on the inner wall of the fixing hole 6, and when the latch member is inserted into the fixing hole 6, the elastic fixing structure is squeezed and contracted, and when it reaches the hole, the elastic fixing structure pops out and enters the hole, thereby realizing the fixation of the latch member.

[0043] The connecting member 7 includes a connecting cap 8 and a connecting rod 9. The cross-sectional shapes of the connecting cap 8 and the connecting rod 9 are also preferably circular, and the cross-sectional diameter of the connecting cap 8 is larger than the cross-sectional diameter of the connecting rod 9. The connecting rod 9 is inserted / screwed into the fixing hole 6 through the through hole 5 until the bottom of the connecting cap 8 fits with the bottom of the positioning portion 3.

[0044] In order to hide the connecting piece 7 and make the gas stove more beautiful and easy to clean after assembly, after the connecting piece 7 is installed, the height of the top of its connecting cap 8 should be lower than the height of the plane of the liquid collecting pan 2. Therefore, when producing the connecting piece 7, the thickness of the connecting cap 8 should be controlled to be less than or equal to the depth of the depression of the positioning part 3; or, when producing the liquid collecting pan 2, the depth of the depression of the positioning part 3 should be controlled to be greater than or equal to the thickness of the connecting cap 8.

[0045] In order to facilitate installation, the horizontal width of the bottom of the positioning portion 3 should be smaller than the horizontal width of the top of the positioning groove 4, and there should be a large width difference between the two. At this time, when the liquid tray 2 is installed, the positioning portion 3 is easier to enter the positioning groove 4. However, if the width difference between the positioning portion 3 and the positioning groove 4 is large, there will be a large gap between the positioning portion 3 after the positioning portion 3 is inserted into the positioning groove 4, resulting in relative movement of the positioning portion 3 and the positioning groove 4 in the horizontal direction during the process of fixing the liquid tray 2. Therefore, the positioning portion 3 and the positioning groove 4 are both inclined from the center to the periphery, and the inclination angle of their side walls is greater than or equal to 5°.

[0046] Preferably, the side walls of the positioning portion 3 and the positioning groove 4 have the same inclination angle, and the outer side wall of the positioning portion 3 is relatively parallel to the side wall of the positioning groove 4. At the same time, in order to avoid a large gap between the positioning portion 3 and the positioning groove 4 after the positioning portion 3 is inserted into the positioning groove 4, the distance between the outer side wall of the positioning portion 3 and the side wall of the positioning groove 4 should be less than or equal to 0.1 mm.

[0047] Preferably, the side wall of the positioning portion 3 and the plane of the liquid receiving tray 2 , and the side wall of the positioning portion 3 and the bottom wall are connected via arc-shaped transition surfaces 11 .

[0048] A fixing portion 10 is provided on the outer circumference of the burner 1, and the positioning groove 4 and the fixing hole 6 are provided on the fixing portion 10. The fixing portion 10 is provided on the outer circumference of the top of the burner head of the burner 1 and protrudes from the burner head body.

[0049] In order to make the liquid tray 2 evenly stressed after being fixed and avoid tilting in the vertical direction, the fixing parts 10 are evenly arranged at multiple locations along the outer circumference of the burner 1 at the same distance. Figure 3 As shown, in the gas cooker provided in this embodiment, the liquid receiving tray 2 is provided with three positioning parts 3, and correspondingly, three fixing parts 10 are evenly arranged at the same distance along the outer peripheral side of the burner 1, and the angle between every two adjacent fixing parts 10 and the center of the burner 1 is 120°.

[0050] When the gas cooker is used in daily life, oil spills and the like flow into the fixing hole 6 and accumulate in the fixing hole 6, which is not only difficult to clean, but also may cause the oil spills to accumulate at the bottom of the fixing hole 6, occupying the space of the connecting rod 9, making it difficult for the connecting member 7 to be hidden below the plane of the liquid receiving pan 2. To solve the above problem, the fixing hole 6 passes through the fixing part 10, and the fixing hole 6 is a through hole at this time, which is easy to clean.

[0051] If the fixing hole 6 does not penetrate the fixing portion 10, when the connecting member 7 is inserted into the fixing hole 6, if the length of the connecting rod 9 is longer than the length of the fixing hole 6, the connecting rod 9 cannot enter the fixing hole 6 completely, and the top of the connecting cap 8 will be higher than the plane of the liquid tray 2, and the connecting member 7 cannot be hidden below the plane of the liquid tray 2. Therefore, during production and daily disassembly and assembly, there are certain requirements for the length of the connecting member 7, which will reduce the practicality of the gas cooker.

[0052] To solve the above problem, the fixing hole 6 passes through the fixing part 10. At this time, if the length of the connecting rod 9 is long, after the connecting piece 7 is inserted into the fixing hole 6, it will pass through the fixing hole 6 and extend from the bottom of the fixing part 10. At this time, the fixing part 10 has a high adaptability to the length of the connecting piece 7, which improves the practicality of the gas cooker.

[0053] The burner 1 comprises an outer fire cover and an inner fire cover, wherein the outer fire cover is sleeved on the outer side of the inner fire cover. The outer fire cover is annular so as to be sleeved on the outer side of the inner fire cover.

[0054] The burner 1 also includes a thermocouple, which is used to implement flameout protection and is installed at the fire outlet of the inner fire cover.

[0055] The burner 1 also includes an ignition needle, which is fixed on the partition between the inner side of the outer fire cover and the outer side of the inner fire cover, close to the fire hole of the inner fire cover. When the fire hole of the inner fire cover releases air and gas, the ignition needle releases an electric spark to ignite the air and gas released from the fire hole, thereby realizing ignition and combustion of the burner.

[0056] The burner 1 further includes an air inlet, which is arranged below the outer fire cover and is used to supplement air when the burner 1 is burning. Optionally, there are multiple air inlets, which are arranged in sequence and spaced apart along the circumference of the burner head of the burner 1, so that the circumferential supply of air can be ensured when the burner 1 is burning.

[0057] Preferably, the cross-sectional area of ​​the air inlet decreases from the outside to the inside. This structure can compress the air, increase the oxygen density of the incoming air, and improve the combustion efficiency of the burner 1.

[0058] like Figure 1 and Figure 3 As shown, the liquid receiving pan 2 provided in this embodiment is square, and is fixed to the outer peripheral side of the burner 1 by connecting with the fixing portion 10 of the burner 1. A circular cavity having a shape matching the burner head of the burner 1 and used to accommodate the burner head of the burner 1 is provided at the center of the liquid receiving pan 2. A circular cavity for accommodating the burner head of the burner 1 is also provided at the center of the gas stove panel, and is sleeved on the outer peripheral side of the burner 1.

[0059] The liquid collecting pan 2 includes a fitting surface surrounding the liquid collecting pan 2 and a plane of the liquid collecting pan 2 surrounded by the fitting surface. There is a height difference between the fitting surface and the plane of the liquid collecting pan 2, and the height of the plane of the liquid collecting pan 2 is higher than the fitting surface. The liquid collecting pan 2 is fixed above the gas stove panel through a fixing structure with the burner 1, and the fitting surface fits the gas stove panel to prevent stains such as oil spills from entering the gas stove through the gap between the liquid collecting pan 2 and the gas stove panel, resulting in a sanitary dead corner that is difficult to clean.

[0060] After adopting the above technical solution, the gas cooker provided by the utility model has the following beneficial effects compared with the prior art:
