Technical Field
[0001] This utility model belongs to the field of stove technology, and in particular relates to stove components with pulse igniter heat insulation cover. Background Technology
[0002] The pulse igniter is the core ignition component of a gas stove. It is usually installed inside the bottom shell of the stove and is exposed to high-temperature air for a long time, which can easily lead to problems such as malfunction and aging, resulting in a shorter service life. Some stoves install a heat insulation cover on the bottom shell to protect the pulse igniter from heat. However, the heat insulation cover is fixed with bolts, which makes it inconvenient to disassemble and install and results in low operating efficiency.
[0003] Existing patent document (publication number: CN212618463U) discloses "a gas stove with pulse-controlled ignition", the technical solution of which is that the pulse igniter is exposed and installed in the base, which also has the above-mentioned technical problems. Summary of the Invention
[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a stove assembly with a heat insulation cover for a pulse igniter. The structure is novel. The heat insulation cover shields the pulse igniter, which can prevent the high-temperature air in the bottom shell of the stove from directly contacting the pulse igniter and causing it to easily malfunction or age, thereby extending the service life of the pulse igniter.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A cooker assembly with a heat insulation cover for a pulse igniter includes: a cooker base, a pulse igniter, and a burner. The pulse igniter and burner are mounted on the cooker base. The burner includes an ignition needle, a thermocouple, a center burner cap, and a center burner cap seat. The key feature is that a heat insulation cover is connected to the cooker base, shielding the pulse igniter. The heat insulation cover has a flange on its side, and the cooker base has an upward protrusion. A slot corresponding to the flange is opened on the side of the upward protrusion facing the heat insulation cover, allowing for a detachable and retaining connection of the cooker base to the heat insulation cover. This cooker assembly has a novel structure. The heat insulation cover shields the pulse igniter, preventing the high-temperature air inside the cooker base from directly contacting the pulse igniter and causing malfunctions or aging, thus extending the lifespan of the pulse igniter.
[0007] Furthermore, the heat insulation cover has openings for wiring to pass through, which avoids messy wiring and facilitates subsequent maintenance.
[0008] Furthermore, the bottom surface of the stove base is provided with a recessed part, and the recessed part is provided with heat dissipation holes corresponding to the position of the pulse igniter. The recessed part creates space for air flow, which helps the air to dissipate the heat from the surface of the pulse igniter through the heat dissipation holes, thus preventing the pulse igniter from overheating and affecting normal use.
[0009] Furthermore, the bottom of the cooktop is equipped with support feet, which improves the stability of the cooktop when placed and allows for airflow at the bottom, thus facilitating heat dissipation.
[0010] Furthermore, a protrusion is provided on the side wall of the center burner cap, and a flame-preserving hole is provided on the protrusion, which communicates with the mixing chamber of the center burner cap seat. The flame-preserving hole faces the thermocouple, which can prevent the flame of the flame-preserving hole from burning the thermocouple when the flame of the center burner cap's flame outlet swings, thus preventing the flame from going out.
[0011] Furthermore, the central burner cap is equipped with a brim, and the ignition needle is located below the projection of the brim. This prevents soup overflowing from the pot from falling directly onto the ignition needle and causing it to fail to ignite, thus providing good protection.
[0012] Furthermore, the top of the central burner cap is equipped with a liquid collection pit, which can collect liquid droplets falling from the bottom of the pot, making cleaning convenient.
[0013] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:
[0014] 1. The heat insulation cover shields the pulse igniter, providing a certain degree of heat insulation and preventing the high-temperature air inside the stove's bottom shell from directly contacting the pulse igniter, which could easily cause malfunctions and aging, thus extending the lifespan of the pulse igniter. During installation, the side wall of the heat insulation cover is squeezed to make the flange embed into the slot, thus limiting the heat insulation cover to the stove's bottom shell. It is not easy to loosen freely, has high installation stability, and replaces the screw fixing method. Disassembly is also simple and labor-saving.
[0015] 2. The flame protection hole faces the thermocouple to prevent the flame from the flame protection hole from burning the thermocouple when the flame from the center flame cap's outlet hole swings, thus preventing the flame from going out.
[0016] 3. The ignition needle is located below the projection of the brim, which can prevent soup overflowing from the pot from falling directly onto the ignition needle and causing it to fail to ignite, thus providing good protection.
[0017] 4. The recessed section creates space for airflow, which helps the air dissipate the heat from the surface of the pulse igniter through the heat dissipation holes, preventing the pulse igniter from overheating and affecting its use. Attached Figure Description

Detailed Implementation
[0025] like Figures 1 to 5 As shown, this utility model relates to a stove assembly with a pulse igniter heat insulation cover, comprising: a stove base shell 1, a power adapter 2, a pulse igniter 3, and a burner 4. The pulse igniter 3, power adapter 2, and burner 4 are respectively fixed on the stove base shell 1. The burner 4 includes an ignition needle 5, a thermocouple 6, a center burner cap 7, and a center burner cap seat 8. The center burner cap 7 is located on the center burner cap seat 8. The side walls of the center burner cap 7 protrude outwards, forming protrusions 9 and brims 10. The ignition needle 5 is located below the projection of the brims 10, which can prevent soup overflowing from the pot from falling directly onto the ignition needle 5 and causing ignition failure, thus providing good protection.
[0026] The protrusion 9 is provided with a flame-preserving hole 11 that communicates with the mixing chamber of the central flame cap seat 8. The flame-preserving hole 11 faces the thermocouple 6, and the distance between the flame-preserving hole 11 and the thermocouple 6 is 3-5mm. This can prevent the flame of the flame-preserving hole 11 from burning the thermocouple 6 when the flame of the flame outlet of the central flame cap 7 swings, so as not to cause the flame to go out.
[0027] The top of the center burner cap 7 is provided with a liquid collection pit 12, which can collect liquid droplets falling from the bottom of the pot and is easy to clean.
[0028] A heat insulation cover 13 is connected to the bottom shell 1 of the stove. The heat insulation cover 13 is made of nickel-based alloy and has good heat insulation performance and elasticity. The heat insulation cover 13 shields the pulse igniter 3 and the power adapter 2, and plays a certain role in heat insulation. It prevents the high temperature air inside the bottom shell 1 of the stove from directly contacting the pulse igniter 3 and the power adapter 2, which could easily cause malfunctions and aging, thereby extending the service life.
[0029] The heat insulation cover 13 has an outwardly bent side forming a flange 14. The bottom shell 1 of the stove is provided with an upper protrusion 15. The distance between the two oppositely distributed upper protrusions 15 is adapted to the length of the heat insulation cover 13. The upper protrusion 15 has a slot 16 corresponding to the flange 14 on the side facing the heat insulation cover 13, so that the bottom shell 1 of the stove can be detachably and limitedly connected to the heat insulation cover 13.
[0030] During installation, the side wall of the heat insulation cover 13 is squeezed to make the flange 14 embed into the slot 16, so that the heat insulation cover 13 is limited on the bottom shell 1 of the stove, which is not easy to loosen freely, has high installation stability, replaces the screw fixing method, and is also simple to disassemble and easy to operate.
[0031] The heat insulation cover 13 has a wire passage 17 on its side, which allows the wires to pass through, avoiding messy wire distribution and facilitating subsequent maintenance.
[0032] The bottom surface of the cooktop shell 1 is provided with a recessed part 18, and the recessed part 18 is provided with heat dissipation holes 19 corresponding to the position of the pulse igniter 3. The recessed part 18 creates space for air flow, which helps the air to dissipate the heat from the surface of the pulse igniter 3 through the heat dissipation holes 19, thus preventing the pulse igniter 3 from overheating and affecting normal use.
[0033] The bottom of the stove base shell 1 is equipped with support feet at all four corners. This improves the stability of the stove base shell 1 when it is placed, and also allows for airflow space at the bottom of the stove base shell 1, which is conducive to heat dissipation.
[0034] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
