[0027] In related technologies, the burner and gas valve of a cooktop can be directly plugged in (direct plug connection) or connected via a pipe (pipe connection), with different installation methods adapting to different accessories. In existing technologies, the bottom shell of cooktops has a compact space, and each bottom shell typically only supports one installation method—either direct plug connection or pipe connection—making it difficult to accommodate both. Furthermore, different cooktops have different burner installation requirements, necessitating the creation of two different bottom shell molds during the cooktop manufacturing process, thus increasing production costs.

[0028] The following is for reference. Figures 1-4 Description of a bottom shell assembly 1 for a stove according to an embodiment of the present invention.

[0029] like Figures 1-4 As shown, the bottom shell assembly 1 for a stove according to the present invention includes: a bottom shell body 10, the bottom shell body 10 having a first mounting area 10a and a second mounting area 10b spaced apart from each other in a first direction, the first mounting area 10a and the second mounting area 10b being respectively adapted to mount a burner, the burner having an air inlet end, the bottom shell body 10 also having a gas valve mounting area 10c, the gas valve mounting area 10c being adapted to mount a gas valve, the gas valve being adapted to communicate with the air inlet end; wherein the bottom shell body 10 has a first set of air supply holes and a second set of air supply holes, the air inlet end communicating with the first set of air supply holes and / or the second set of air supply holes.

[0030] Specifically, the bottom shell assembly 1 is applied to the cooktop and includes at least the bottom shell body 10. The first mounting area 10a and the second mounting area 10b on the bottom shell body 10 are respectively adapted to install the burners. The burners may include a first burner 21 and a second burner 22. The first burner 21 and the second burner 22 are respectively connected to a gas valve located in the gas valve mounting area 10c, so that the gas valve can supply gas to the first burner 21 and the second burner 22, and both the first burner 21 and the second burner 22 can release gas.

[0031] During stove use, gas combustion requires an oxygen supply. The gas inlet connects the external and internal spaces of the bottom shell 10, and can be directly opposite the air inlet of the burner. As gas flows from the gas valve to the first burner 21 and the second burner 22, airflow from the external space of the bottom shell 10 can flow into the internal space through the gas inlet. Under the pressure of the gas, it mixes with the gas at the air inlet of the burner and follows the gas flow to the first burner 21 and the second burner 22 for combustion. The first and second sets of gas inlets are positioned differently, allowing the burner installation location to be selected according to installation requirements.

[0032] According to the present invention, the bottom shell assembly 1 for stove is designed with air inlet holes at different positions of the bottom shell body 10, so that the bottom shell body 10 can accommodate multiple installation methods of the burner and adapt to multiple installation requirements of the burner, thereby improving the applicability of the bottom shell assembly 1, reducing the mold cost of the bottom shell assembly 1, and thus reducing the production cost of the stove.

[0033] Furthermore, the first set of air inlet holes is located at the edges of the first mounting area 10a and the second mounting area 10b facing each other, and the second set of air inlet holes is located between the first mounting area 10a and the gas valve mounting area 10c, and between the second mounting area 10b and the gas valve mounting area 10c.

[0034] During the use of the stove, the combustion of gas requires an oxygen supply. The first set of gas inlets connects the external space and internal space of the bottom shell body 10. The first set of gas inlets can be directly opposite the air inlet of the burner. As the gas flows from the gas valve to the first burner 21 and the second burner 22, the airflow in the external space of the bottom shell body 10 can flow into the internal space of the bottom shell body 10 through the first set of gas inlets. Under the action of gas pressure, the airflow mixes with the gas at the air inlet of the burner and flows with the gas to the first burner 21 and the second burner 22 to facilitate combustion. Similarly, the second set of air inlets also connects the external space and internal space of the bottom shell body 10. The second set of air inlets can be directly opposite the air inlet of the burner. During the process of the gas flowing from the gas valve to the first burner 21 and the second burner 22, the airflow in the external space of the bottom shell body 10 can flow into the internal space of the bottom shell body 10 through the second set of air inlets. Under the action of the gas pressure, the gas mixes with the gas at the air inlet of the burner and flows with the gas to the first burner 21 and the second burner 22 so as to facilitate the combustion of the gas.

[0035] The first and second sets of air supply holes are positioned differently. The first set is located at the edges of the first installation area 10a and the second installation area 10b facing each other, while the second set is located between the first installation area 10a and the gas valve installation area 10c, and between the second installation area 10b and the gas valve installation area 10c. When the gas inlet of the burner head is directly opposite the second set of air supply holes, the distance between the burner head and the gas valve is small, and the connection length is short. In this case, the burner head and the gas valve can be directly plugged in, i.e., a direct plug-in connection. When the gas inlet of the burner head is directly opposite the first set of air supply holes, the distance between the burner head and the gas valve is larger, and the connection length is longer. In this case, the burner head and the gas valve can be connected through the connecting pipe 27, i.e., a pipe-connected connection. The installation position of the burner head can be selected according to the installation requirements.

[0036] Of course, the first burner head 21 and the second burner head 22 can be connected by either a direct insertion type or a pipe connection. In this case, the air inlet ends of the first burner head 21 and the second burner head 22 are connected to either the first group of air supply holes or the second group of air supply holes. Alternatively, the first burner head 21 and the second burner head 22 can be connected by either a direct insertion type or a pipe connection, in which case the air inlet ends of the first burner head 21 and the second burner head 22 are connected to the first group of air supply holes and the second group of air supply holes, respectively. The design can be tailored to the actual installation requirements of different burners.

[0037] According to some embodiments of this utility model, such as Figures 1-2 As shown, a first igniter mounting area 10d and a second igniter mounting area 10e are formed on the bottom shell body 10. The first igniter mounting area 10d is located between the first mounting area 10a and the second mounting area 10b, and is suitable for installing an igniter when the air intake end is connected to the second set of air supply holes. The second igniter mounting area 10e is located adjacent to one side edge of the bottom shell body 10, and is suitable for installing an igniter when the air intake end is connected to the first set of air supply holes.

[0038] Specifically, since the second set of gas supply holes is located between the first installation area 10a and the gas valve installation area 10c, and between the second installation area 10b and the gas valve installation area 10c, when the gas inlet end of the burner head is directly opposite the second set of gas supply holes, the burner head and the gas valve are directly connected. The first igniter installation area 10d is located between the first installation area 10a and the second installation area 10b. At this time, the igniter can be set in the first igniter installation area 10d to achieve that the installation of the igniter and the burner head does not interfere with each other, and the igniter is the first igniter 25. Since the first set of gas supply holes is located at the edges of the first installation area 10a and the second installation area 10b facing each other, when the gas inlet end of the burner head is directly opposite the first set of gas supply holes, the burner head and the gas valve are connected by a pipe. The second igniter installation area 10e is located near one edge of the bottom shell body 10. At this time, the igniter can be installed in the second igniter installation area 10e so that the installation of the igniter and the burner head does not interfere with each other, and the igniter is the second igniter 26.

[0039] According to some embodiments of this utility model, such as Figures 1-2 As shown, a first protrusion 11 and a second protrusion 12 spaced apart in a first direction are respectively formed on the bottom shell body 10. A first mounting area 10a is formed on the top surface of the first protrusion 11, and a second mounting area 10b is formed on the top surface of the second protrusion 12. Specifically, the design of the first protrusion 11 and the second protrusion 12, and the design of mounting the burner head on the first protrusion 11 and the second protrusion 12, can improve the mounting strength of the burner head and prevent the bottom shell body 10 from deforming during the installation of the burner head. At the same time, the first protrusion 11 and the second protrusion 12 are spaced apart in the first direction so that the first burner head 21 and the second burner head 22 can be installed spaced apart in the first direction. In some embodiments, the first protrusion 11 and the second protrusion 12 can be formed by stamping on the bottom shell body 10.

[0040] According to some embodiments of this utility model, such as Figures 1-2 As shown, a third protrusion 13 is formed on the bottom shell body 10. The third protrusion 13 is located between the first protrusion 11 and the second protrusion 12, and a first igniter mounting area 10d is formed on the end face of the third protrusion 13. A through-hole heat dissipation hole 10f is formed on the third protrusion 13. Specifically, designing the third protrusion 13 and mounting the first igniter 25 on the third protrusion 13 can improve the mounting strength of the first igniter 25 and prevent the bottom shell body 10 from deforming during the installation of the first igniter 25. The heat dissipation hole 10f formed on the third protrusion 13 can achieve heat dissipation of the first igniter 25 during use. At the same time, the third protrusion 13 is located between the first protrusion 11 and the second protrusion 12 so that the first burner head 21, the first igniter 25 and the second burner head 22 can be installed at intervals in the first direction. In some embodiments, the third protrusion 13 can be formed by stamping on the bottom shell body 10.

[0041] According to some embodiments of this utility model, such as Figures 1-2 As shown, a first groove 110 is formed between the first boss 11 and the third boss 13, and a second groove 120 is formed between the second boss 12 and the third boss 13; wherein the first group of air supply holes includes a first air supply hole 101 and a second air supply hole 102, and the first air supply hole 101 and the second air supply hole 102 are located in the first groove 110 and the second groove 120, respectively.

[0042] Specifically, during the use of the stove, the combustion of gas requires an oxygen supply. When the burner and the gas valve are connected by a pipe, the first set of gas supply holes connects the external space and internal space of the bottom shell body 10. The first set of gas supply holes includes a first gas supply hole 101 and a second gas supply hole 102. The first groove 110 formed between the first protrusion 11 and the third protrusion 13 is provided with the first gas supply hole 101, which is directly opposite to the connection between the first burner 21 and the gas valve. The second groove 120 formed between the second protrusion 12 and the third protrusion 13 is provided with the second gas supply hole 102, which is directly opposite to the connection between the second burner 22 and the gas valve.

[0043] During the flow of gas from the gas valve to the first burner head 21, the airflow from the external space of the bottom shell body 10 can flow into the internal space of the bottom shell body 10 through the first air supply hole 101. Under the action of gas pressure, the airflow mixes with the gas at the connection between the first burner head 21 and the gas valve, and flows with the gas towards the first burner head 21 for combustion. Similarly, during the flow of gas from the gas valve to the second burner head 22, the airflow from the external space of the bottom shell body 10 can flow into the internal space of the bottom shell body 10 through the second air supply hole 102. Under the action of gas pressure, the airflow mixes with the gas at the connection between the second burner head 22 and the gas valve, and flows with the gas towards the second burner head 22 for combustion.

[0044] According to some embodiments of this utility model, such as Figures 1-2 As shown, the bottom wall of the first groove 110 is formed with a first air guide 1101 extending toward the top, and the top of the first air guide 1101 is formed with a first air supply hole 101; the bottom wall of the second groove 120 is formed with a second air guide 1201 extending toward the top, and the top of the second air guide 1201 is formed with a second air supply hole 102.

[0045] Specifically, the first air guide 1101 is adapted to guide the airflow from the external space of the bottom shell body 10 through the first air inlet 101 toward the connection between the first burner head 21 and the gas valve, so that air can follow the gas to the first burner head 21, facilitating the combustion of the gas at the first burner head 21. The second air guide 1201 is adapted to guide the airflow from the external space of the bottom shell body 10 through the second air inlet 102 toward the connection between the second burner head 22 and the gas valve, so that air can follow the gas to the second burner head 22, facilitating the combustion of the gas at the second burner head 22.

[0046] According to some embodiments of this utility model, such as Figures 1-2 As shown, the gas valve mounting area 10c is located on one side of the first igniter mounting area 10d in the second direction, and the second direction is orthogonal to the first direction; the second group of gas supply holes includes a third gas supply hole 103 and a fourth gas supply hole 104. The third gas supply hole 103 is located between the gas valve mounting area 10c and the first boss 11, and the fourth gas supply hole 104 is located between the gas valve mounting area 10c and the second boss 12.

[0047] Specifically, the first installation area 10a, the first igniter installation area 10d, and the second installation area 10b are arranged sequentially in the first direction. The gas valve installation area 10c is located on one side of the first igniter installation area 10d in the second direction, that is, on one side of the first installation area 10a, the first igniter installation area 10d, and the second installation area 10b in the second direction. During the use of the stove, the combustion of gas requires an oxygen supply. When the burner and the gas valve are directly connected, the second set of gas supply holes connects the external space and the internal space of the bottom shell body 10. The second set of gas supply holes includes a third gas supply hole 103 and a fourth gas supply hole 104. The third gas supply hole 103 is directly opposite the connection between the first burner 21 and the gas valve, and the fourth gas supply hole 104 is directly opposite the connection between the second burner 22 and the gas valve.

[0048] During the flow of gas from the gas valve to the first burner head 21, the airflow from the external space of the bottom shell body 10 can flow into the internal space of the bottom shell body 10 through the third air supply hole 103. Under the action of gas pressure, the airflow mixes with the gas at the connection between the first burner head 21 and the gas valve, and flows with the gas towards the first burner head 21 for combustion. Similarly, during the flow of gas from the gas valve to the second burner head 22, the airflow from the external space of the bottom shell body 10 can flow into the internal space of the bottom shell body 10 through the fourth air supply hole 104. Under the action of gas pressure, the airflow mixes with the gas at the connection between the second burner head 22 and the gas valve, and flows with the gas towards the second burner head 22 for combustion.

[0049] According to some embodiments of this utility model, such as Figures 1-2As shown, the third air supply hole 103 and the fourth air supply hole 104 are inclined to each other in the direction close to the first igniter installation area 10d. At this time, the third air supply hole 103 and the fourth air supply hole 104 occupy less space in the second direction, which can reduce the size of the bottom shell body 10 in the second direction. In addition, the extension direction of the second group of air supply holes is different from that of the first group of air supply holes, which can differentiate the second group of air supply holes from the first group of air supply holes. This makes it easy for operators to quickly distinguish the second group of air supply holes from the first group of air supply holes, and realizes a foolproof design that facilitates different installations of the burner head.

[0050] According to some embodiments of this utility model, such as Figures 1-2 As shown, a third groove 130 is formed between the first boss 11 and the gas valve mounting area 10c, and a fourth groove 140 is formed between the second boss 12 and the gas valve mounting area 10c; wherein the bottom wall of the third groove 130 forms a third air guide portion 1301 extending toward the top, and the top of the third air guide portion 1301 forms a third air supply hole 103; the bottom wall of the fourth groove 140 forms a fourth air guide portion 1401 extending toward the top, and the top of the fourth air guide portion 1401 forms a fourth air supply hole 104.

[0051] Specifically, a third air guide 130 is provided in the third groove 130 formed between the first protrusion 11 and the gas valve mounting area 10c, and a fourth air guide 1401 is provided in the fourth groove 140 formed between the second protrusion 12 and the gas valve mounting area 10c. The third air guide 1301 is adapted to guide the airflow from the external space of the bottom shell body 10 through the third air supply hole 103 toward the connection between the first burner head 21 and the gas valve, so that air can follow the gas to the first burner head 21, facilitating the combustion of the gas at the first burner head 21. The fourth air guide 1401 is adapted to guide the airflow from the external space of the bottom shell body 10 through the fourth air supply hole 104 toward the connection between the second burner head 22 and the gas valve, so that air can follow the gas to the second burner head 22, facilitating the combustion of the gas at the second burner head 22.

[0052] According to some embodiments of this utility model, such as Figures 1-2 As shown, a battery box mounting hole 10g is formed on the bottom shell body 10. The battery box mounting hole 10g and the second igniter mounting area 10e are respectively located adjacent to the two side edges of the bottom shell body 10 in the first direction. Specifically, the battery box mounting hole 10g is suitable for mounting the battery box 24. The battery box mounting hole 10g, the gas valve mounting area 10c, and the second igniter mounting area 10e are arranged sequentially in the first direction.

[0053] exist Figures 1-2In the specific embodiment shown, the bottom shell assembly 1 includes a bottom shell body 10. The bottom shell body 10 forms a first mounting area 10a, a first igniter mounting area 10d, and a second mounting area 10b arranged sequentially in a first direction. The first mounting area 10a and the second mounting area 10b are respectively adapted to install a first burner head 21 and a second burner head 22. The first igniter mounting area 10d is adapted to install a first igniter 25. The bottom shell body 10 also forms a battery box mounting hole 10g, a gas valve mounting area 10c, and a second igniter mounting area 10e arranged sequentially in the first direction.
