Description

Technical Field

[0001] This application belongs to the field of kitchen appliance technology, specifically relating to a gas stove. Background Technology

[0002] When a gas stove is in normal use, the flame burns above the burner. If there is wind blowing on the burner, it will blow the flame into the burner or even into the stove. When the flame burns inside for a long time, it will damage the internal components of the gas stove, which will not only affect the lifespan of the gas stove, but may also pose a safety risk. Summary of the Invention

[0003] This application provides a gas stove designed to at least partially prevent flames from damaging internal components of the gas stove, thus avoiding technical problems that could affect the lifespan of the gas stove and potentially create safety risks.

[0004] In a first aspect of this application, a gas stove is provided, the gas stove comprising: a bracket; a burner head mounted on the bracket; a valve body connected to the burner head, the valve body being controllably open and closed to control whether gas is supplied to the burner head; an igniter for generating a flame in the burner head; and a thermostat mounted on the bracket, the thermostat being used to acquire the temperature of the burner head; wherein the thermostat and the igniter are connected, and the igniter and the valve body are connected.

[0005] The gas stove provided in this application uses a thermostat to obtain the temperature of the burner head. When the temperature inside the burner head obtained by the thermostat exceeds the set value, the thermostat is disconnected. After the igniter detects the disconnection of the thermostat, the igniter controls the valve body to operate, the valve body closes, and the valve body stops supplying gas to the burner head, thereby cutting off the gas supply to the burner head, extinguishing the flame on the burner head, preventing the flame from burning the internal components of the gas stove for a long time, improving the service life of the gas stove, and ensuring safety.

[0006] In some embodiments, the gas stove further includes: an ignition needle, assembled on the burner head, the ignition part of the ignition needle being located inside the burner head, and the ignition needle being connected to the igniter.

[0007] In some implementations, the temperature sensing end of the thermostat faces the inside of the burner head.

[0008] In some implementations, two or more thermostats are arranged circumferentially around the burner head.

[0009] In some embodiments, the gas stove further includes: a thermocouple mounted on the burner head, the temperature sensing part of the thermocouple being disposed inside the burner head, the temperature sensing part of the thermocouple being adjacent to the ignition part of the ignition needle, and the thermocouple being connected to the valve body.

[0010] In some implementations, the bracket is fitted around the burner head, and the temperature sensing end of the thermostat is close to the burner head's flame port.

[0011] In some embodiments, the top of the support is provided with a stop, and the burner head is provided with an overlapping part, which overlaps the stop of the support.

[0012] In some embodiments, the gas stove further includes a power source connected to the igniter.

[0013] In some implementations, the gas stove further includes a microswitch connected to the igniter.

[0014] In a second aspect of this application, another gas stove is provided, the gas stove comprising: a bracket; a burner head mounted on the bracket; a valve body connected to the burner head, the valve body being controllably open and closed to control whether gas is supplied to the burner head; a thermocouple mounted on the burner head, the temperature sensing part of the thermocouple being disposed inside the burner head; and a thermostat mounted on the bracket, the thermostat being used to acquire the temperature of the burner head; wherein the thermocouple is connected to the valve body via the thermostat.

[0015] The gas stove provided in this application uses a thermostat to obtain the temperature of the burner head. When the temperature inside the burner head obtained by the thermostat exceeds the set value, the thermostat is disconnected, the thermocouple cannot continue to supply power to the valve body, thereby closing the valve body and stopping the gas supply to the burner head. This cuts off the gas supply to the burner head, extinguishes the flame on the burner head, prevents the flame from burning the internal components of the gas stove for a long time, improves the service life of the gas stove, and ensures safety.

[0035] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] In modern household gas stoves, during normal combustion, the speed at which the gas-air mixture leaves the burner holes is equal to the combustion speed, forming a stable flame on the burner holes, which burns above the burner head.

[0037] If there is wind blowing on the burner head, it will blow the flame into the burner head or even into the stove. When the flame burns inside for a long time, it will damage the internal components of the gas stove, which will not only affect the service life of the gas stove, but may also pose a safety risk.

[0038] In related technologies, adding a heat insulation plate to the burner head can only prevent the flame from spreading further, but it cannot completely shut off the gas supply. The aforementioned technical problem still exists: the flame can burn the internal components of the gas stove, which not only affects the service life of the gas stove, but may even pose a safety risk.

[0039] To address the aforementioned technical problems, this application provides a gas stove that can immediately cut off the gas supply when a flame blows into the burner head or even the interior of the stove, extinguishing the flame on the burner head and preventing prolonged burning of internal components, thus extending the lifespan of the gas stove and ensuring safety. The following is illustrated in the appendix... Figure 1 - Appendix Figure 4 Further details about the gas stove are described.

[0040] Figure 1 A schematic diagram of the structure of a gas stove according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 Top view after removing the top of the enclosure. Figure 3 It shows Figure 1 The assembly diagram of the burner head 120 is shown. (Combined with...) Figures 1-3 The gas stove includes a support 110, a burner head 120, an igniter 130, an ignition needle 140, a thermocouple 150, and a valve body 160. The burner head 120 is mounted on the support 110 and has flame holes 121. The valve body 160 is connected to the burner head 120 and can be controlled to open and close to control whether gas is supplied to the burner head 120. The igniter 130 is connected to the ignition needle 140, which is mounted on the burner head 120. The ignition part of the ignition needle 140 is located inside the burner head 120. The thermocouple 150 is mounted on the burner head 120, and its temperature sensing part is located inside the burner head 120, adjacent to the ignition part of the ignition needle 140. The thermocouple 150 is connected to the valve body 160.

[0041] When valve body 160 is opened, gas is supplied to burner head 120 and injected from burner head 120's flame port 121. Igniter 130 and ignition needle 140 work together to complete the ignition process. Igniter 130 provides the necessary electrical energy and ignition signal, while ignition needle 140 converts electrical energy into high voltage and generates an electric spark to ignite the fuel, thus forming a flame at burner head 120's flame port 121. Simultaneously, thermocouple 150 senses the presence of the flame and controls the opening state of valve body 160. Once the flame is ignited, thermocouple 150 starts working, controlling valve body 160 to be in the open state, continuously supplying gas to burner head 120. If the flame goes out or thermocouple 150 malfunctions, valve body 160 closes, cutting off the gas supply to burner head 120, thereby ensuring the safe operation of the gas stove.

[0042] In some embodiments, the igniter 130 is a pulse igniter, and the valve body 160 can be a solenoid valve. The valve body 160 can receive corresponding command actions to control whether to supply gas to the burner head 120.

[0043] Combination Figure 1 as well as Figure 2 The gas stove also includes a housing 170, the top of which is a panel, a support 110 located on the top of the panel, the bottom of the burner 120 located inside the housing 170, the top of the burner 120 passing through the panel and protruding from the top of the panel, and a valve body 160 located inside the housing 170 and connected to the burner 120 via a pipe.

[0044] Combination Figure 2 The gas stove also includes a power supply 180, which is connected to the igniter 130 and provides power to the igniter 130. The power supply 180 is usually a rechargeable battery, which is located in the battery compartment of the housing 170 for quick replacement when the power supply 180 is depleted.

[0045] Combination Figure 3 At least a portion of the support 110 is annular, and the support 110 is looped around the burner head 120. The top of the burner head 120 protrudes from the support 110, that is, the top of the burner head 120 is higher than the top of the support 110. Since the flame hole 121 is opened at the top of the burner head 120, the flame generated at the flame hole 121 is located above the support 110, so as to a certain extent avoid the flame burning the support 110 and improve the service life of the support 110.

[0046] Figure 4 An assembly diagram of the burner head 120 and the support 110 is shown, combined with... Figure 3 as well as Figure 4 The top of the support 110 is provided with a stop 111, and the burner head 120 is provided with an overlapping part 122, which overlaps the stop 111 of the support 110. The support 110 constrains the burner head 120 to be stably mounted on the panel, and allows the burner head 120 to be removed from above the support 110 for easy cleaning.

[0047] Combination Figure 4 The burner head 120 is also provided with a limiting part 123 on its periphery. The limiting part 123 presses against the overlapping part 122 and is detachably connected to the bracket 110 by bolts or other components. In this way, the limiting part 123 can further constrain the burner head 120 in the height direction, so that the burner head 120 is stably set on the panel. When it is necessary to remove the burner head 120 from the bracket 110, the connection between the limiting part 123 and the bracket 110 can be removed first, and then the burner head 120 can be taken out from above the bracket 110 to facilitate cleaning of the burner head 120.

[0048] Combination Figure 4 In specific implementation, the gas stove of this application also includes a base 200, multiple supports 110 are provided, multiple supports 110 are provided at intervals around the base 200, the burner head 120 is detachably supported on the base 200, the overlapping part 122 is an annular structure integrally formed around the burner head 120, the limiting part 123 and the support 110 are provided one-to-one, the limiting part 120 is also integrally formed around the burner head 120, the overlapping part 122 is supported by multiple supports 110 and clamped between multiple corresponding limiting parts 123 and supports 110.

[0049] The unique feature of this application is that the gas stove also includes a thermostat 100, which is mounted on the bracket 110. The thermostat 100 is used to obtain the temperature of the burner head 120. If the thermostat 100 confirms that the temperature of the burner head 120 exceeds the set value, it indicates that there is a phenomenon of flame burning inside the burner head 120 for a long time. At this time, the valve body 160 can be controlled to close to stop the gas supply to the burner head 120, thereby cutting off the gas supply, extinguishing the flame on the burner head 120, preventing the flame from burning the internal components of the gas stove for a long time, improving the service life of the gas stove, and ensuring safety.

[0050] Figure 5 A schematic diagram of the electrical principle of a gas stove in one embodiment is shown. (Combined with...) Figure 5 In one embodiment, the thermostat 100 is connected to the igniter 130, and the igniter 130 is connected to the valve body 160. When the temperature inside the burner 120 obtained by the thermostat 100 exceeds the set value, the thermostat 100 is disconnected. After the igniter 130 detects the disconnection of the thermostat 100, the igniter 130 controls the valve body 160 to close, thereby stopping the supply of gas to the burner 120, cutting off the gas supply, extinguishing the flame on the burner 120, preventing the flame from burning the internal components of the gas stove for a long time, improving the service life of the gas stove, and ensuring safety.

[0051] Figure 6 A schematic diagram of the electrical principle of a gas stove according to another embodiment is shown. (Combined with...) Figure 6 In another embodiment, thermocouple 150 is connected to valve body 160 via thermostat 100. When the temperature inside burner 120 obtained by thermostat 100 exceeds the set value, thermostat 100 is disconnected, thermocouple 150 can no longer supply power to valve body 160, thereby closing valve body 160 to stop supplying gas to burner 120, cutting off the gas supply, extinguishing the flame on burner 120, preventing the flame from burning the internal components of the gas stove for a long time, improving the service life of the gas stove, and ensuring safety.

[0052] In both embodiments described above, the thermostat 100 is normally open during gas stove operation, enabling real-time monitoring of the internal temperature of the burner head 120. The thermostat 100 obtains the temperature value within the burner head 120 to control the opening and closing of the valve body 160. The difference between the two embodiments lies in: Figure 3 The illustrated embodiment controls the valve body 160 to close via the igniter 130. Figure 4 The embodiment shown controls the valve body 160 to close by disconnecting the thermocouple 150 and the valve body 160.

[0053] Combination Figure 3 as well as Figure 4 In some embodiments, the thermostat 100 can be detachably mounted on the bracket 110 using screws or other components to facilitate maintenance of the thermostat 100. The temperature sensing end of the thermostat 100 faces the inside of the burner head 120. When the flame is blown into the inside of the burner head 120, the inside of the burner head 120 heats up. Because the temperature sensing end of the thermostat 100 faces the inside of the burner head 120, it can more accurately obtain the internal temperature of the burner head 120, thereby improving the response speed of cutting off the gas supply when the internal temperature of the burner head 120 exceeds the set value.

[0054] Combination Figure 3 as well as Figure 4 In some embodiments, the thermostat 100 is positioned close to the burner hole 121 of the burner head 120. Since the burner head 120 emits flame at the burner hole 121, this arrangement of placing the thermostat 100 close to the burner head 120 allows for timely acquisition of the burner head 120's maximum temperature, thereby improving the response speed of the valve body 160 in closing to some extent.

[0055] In some embodiments, two or more thermostats 100 are arranged circumferentially around the burner head 120, which can comprehensively obtain the temperature of various areas inside the burner head 120 and avoid the phenomenon of local over-burning in the burner head 120, which would prevent the internal temperature of the burner head 120 from being obtained. In a specific implementation, two or more ignition needles 140 are arranged circumferentially around the burner head 120, and each of the two or more ignition needles 140 is connected to an igniter 130. The thermostats 100 and ignition needles 140 are arranged in a one-to-one correspondence, with the thermostat 100 close to the ignition part of the corresponding ignition needle 140. Specifically, two ignition needles 140 can be arranged opposite each other on the central axis of the burner head 120. Correspondingly, two thermostats 100, thermocouples 150, and valve bodies 160 are also arranged, with the thermostat 100 close to the ignition part of the corresponding ignition needle 140, and the thermocouples 150, valve bodies 160, and ignition needles 140 correspondingly cooperate.

[0056] Combination Figure 5 as well as Figure 6In some embodiments, the gas stove also includes a micro switch 190, which is connected to the igniter 130. When the user operates the knob on the control panel, the knob triggers the micro switch 190, which closes, and the igniter 130 operates. The igniter 130 provides electrical energy and an ignition signal to the ignition needle 140, which generates an electric spark to ignite the fuel, thereby forming a flame at the burner hole 121 of the burner head 120.

[0057] In summary, the gas stove provided in this application obtains the temperature of the burner 120 through the thermostat 100. When the temperature inside the burner 120 obtained by the thermostat 100 exceeds the set value, the thermostat 100 is disconnected. At least one of the igniter 130 and the thermocouple 150 controls the valve body 160 to close, thereby stopping the supply of gas to the burner 120, cutting off the gas supply, extinguishing the flame on the burner 120, preventing the flame from burning the internal components of the gas stove for a long time, improving the service life of the gas stove, and ensuring safety. It has good practicality.
