Description

Technical Field

[0001] This invention relates to the field of gas-fired baking equipment technology, and in particular to a temperature control valve assembly, a gas-fired baking device, and a control method thereof. Background Technology

[0002] Currently, in gas-fired baking equipment such as gas ovens, temperature control is achieved by using the principle of thermal expansion and contraction of liquid inside a liquid expansion probe to control the gas flow in the valve body. However, this method has limited functionality and poor temperature control accuracy. Gas ovens that use proportional valves in conjunction with control algorithms to achieve temperature control have complex structures, are expensive, and pose a risk of voltage leakage. Furthermore, the proportional valve adjusts the heat output by regulating the current, and its stability is poor at high temperatures, which may affect the normal operation of the gas oven. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a temperature control valve body assembly, which effectively solves the problems of single function and poor temperature control accuracy when implementing temperature control function in gas baking equipment.

[0004] The above-mentioned technical problems are solved by the following technical solutions:

[0005] A temperature control valve body assembly, used in a gas-fired baking equipment, includes:

[0006] Multiple first temperature control valves, each first temperature control valve including a first valve body and a first plug valve core and a first electromagnetic switch valve core integrated on the first valve body;

[0007] The first valve body is provided with a first air inlet channel, a first plug valve core cavity, a first electromagnetic switch valve core cavity and a first air outlet channel connected in sequence. The first valve body is also provided with a first through hole and a second through hole. The diameter of the first through hole is larger than the diameter of the second through hole. The first air outlet channel is connected to the first electromagnetic switch valve core cavity through the first through hole and the second through hole respectively.

[0008] The first plug valve core is disposed in the first plug valve core cavity and is used to open or close the first air intake passage and the first plug valve core cavity. The first electromagnetic switch valve core cavity is provided with a first electromagnetic switch valve core, which is used to open or close the first through hole.

[0009] Beneficial effects: The first temperature control valve includes a first valve body, which provides a platform for the installation and support of other components and allows the gas to flow within the valve body along a predetermined path. For example, the first valve body sequentially connects a first air inlet channel, a first stopcock valve core cavity, a first electromagnetic switch valve core cavity, and a first air outlet channel. After the gas enters the first stopcock valve core cavity through the first air inlet, it can be sequentially transmitted to the first electromagnetic switch valve core cavity, the first air outlet channel, and finally to the gas-consuming end. A first stopcock valve core is provided on the first valve body, located within the first stopcock valve core cavity, and the connection between the first air inlet channel and the first stopcock valve core cavity can be manually opened or closed. The amount of gas entering the first valve body can be manually controlled by using the first stopcock valve core. The first valve body also includes a first electromagnetic switch valve core, which contains a first electromagnetic switch valve core located within the first electromagnetic switch valve core cavity, used to open or close the first through-hole.

[0010] Furthermore, the first valve body is also provided with a first through hole and a second through hole, and the diameter of the first through hole is larger than the diameter of the second through hole; the first gas outlet channel is connected to the first electromagnetic switch valve core cavity through the first through hole and the second through hole respectively. When the gas baking equipment is in grilling mode and requires a large gas consumption, the valve core of the first electromagnetic switch valve is controlled to open the first through hole, so that the gas is quickly transmitted from the first through hole and the second through hole to the first gas outlet channel to meet the gas flow requirements of the gas baking equipment. When the gas baking equipment is in temperature control mode, more precise control of the gas is required. At this time, the valve core of the first electromagnetic switch valve is closed, and the gas is transmitted to the first gas outlet channel through the smaller diameter second through hole, so that the gas end is in a low flame combustion state, thereby ensuring that the temperature inside the gas baking equipment is relatively constant. By limiting the diameter of the first through hole and the second through hole, the combustion state of the gas baking equipment can be controlled more precisely.

[0011] When the gas baking equipment is working, the amount of gas supplied to the gas-consuming end is increased by opening the first and second through holes of the first temperature control valve, thereby increasing the combustion effect at the gas-consuming end and rapidly raising the temperature inside the gas baking equipment. When the temperature inside the gas baking equipment meets the usage requirements, the first through hole of the first temperature control valve can be closed according to the first electromagnetic switch valve core of the first electromagnetic switch valve core, thereby transmitting gas to the gas-consuming end through the second through hole to reduce the amount of gas at the gas-consuming end. The gas-consuming end burns in a low flame state, thereby maintaining a relatively constant temperature inside the gas baking equipment and realizing the temperature control function of the gas baking equipment.

[0012] The first temperature control valve of this invention can manually control the combustion state of the gas end according to the first stopcock valve core, and can also automatically control the combustion state of the gas end according to the first electromagnetic switch valve core, so as to realize the switching of large and small flames of the gas baking equipment in temperature control mode. Moreover, it is simpler in structure and lower in cost than gas ovens using proportional valves.

[0013] In one embodiment, the first electromagnetic switch valve core further includes a first elastic element sleeved on the first electromagnetic switch valve core; the first electromagnetic switch valve core is provided with a first sealing gasket, and the first elastic element is connected to the first sealing gasket.

[0014] Beneficial effects: A first sealing gasket is provided on the valve core of the first electromagnetic switch valve near the first through hole, and the diameter of the first sealing gasket is larger than the diameter of the first through hole; a first elastic element is sleeved on the valve core of the first electromagnetic switch valve, and one end of the first elastic element is connected to the first sealing gasket, and the other end is connected to the limiting step on the valve core of the first electromagnetic switch valve; when the valve core of the first electromagnetic switch valve is closed, when it is necessary to close the first through hole, the elastic force of the first elastic element can be used to press against the first sealing gasket, thereby sealing the first through hole, without the need to continuously supply power to the valve core of the first electromagnetic switch valve; when the valve core of the first electromagnetic switch valve is open, after the valve core of the first electromagnetic switch valve is working, it relies on the magnet to hold the first sealing gasket, thereby sealing the first through hole, and there is no need to continuously supply power to the valve core of the first electromagnetic switch valve, which can effectively save energy consumption and extend the service life of the external power supply.

[0015] In one embodiment, the first plug valve core further includes a first plug valve core and a first valve stem, the first valve stem being connected to the first plug valve core, and the first plug valve core being disposed within the cavity of the first plug valve core;

[0016] The first plug valve core is provided with a first air inlet and a second air inlet, and the diameter of the first air inlet is larger than the diameter of the second air inlet.

[0017] Beneficial effects: A first stopcock valve core is provided in the first stopcock valve core cavity, and the first stopcock valve core is connected to the first valve stem; by driving the first valve stem to drive the first stopcock valve core to rotate, the on / off state and the amount of gas are controlled. The first stopcock valve core is provided with a first air inlet and a second air inlet, wherein the diameter of the first air inlet is larger than the diameter of the second air inlet; when the first air inlet is opposite to the air inlet channel, the first stopcock valve core cavity is connected to the first air inlet channel, and a larger amount of gas flows into the first stopcock valve core cavity, the first temperature control valve is in a high-flow state, and the gas-consuming end is in a high-flame combustion state; when the second air inlet is opposite to the air inlet channel, the first stopcock valve core cavity is connected to the first air inlet channel, and a smaller amount of gas flows into the first stopcock valve core cavity, the first temperature control valve is in a low-flow state, and the gas-consuming end is in a low-flame combustion state. If neither the first air inlet nor the second air inlet is aligned with the first air inlet channel, the first stopcock valve core blocks the connection between the first stopcock valve core cavity and the first air inlet channel. Manually controlling the combustion state of the gas-fired baking equipment via the first stopcock valve core ensures normal operation of the gas-fired baking equipment even if the first electromagnetic switch valve core fails.

[0018] In one embodiment, a plurality of second temperature control valves are also included, the second temperature control valves including a second valve body and a second plug valve core and a second electromagnetic switch valve core integrated on the second valve body;

[0019] The second valve body is provided with a second air inlet channel, a second plug valve core cavity, a second electromagnetic switch valve core cavity and a third air outlet channel connected in sequence. The second valve body is also provided with a third through hole, and the third air outlet channel is connected to the second electromagnetic switch valve core cavity through the third through hole.

[0020] The second plug valve core is disposed in the second plug valve core cavity and is used to open or close the second air intake passage and the second plug valve core cavity. The second electromagnetic switch valve core cavity is provided with a second electromagnetic switch valve core, which is used to open or close the third through hole.

[0021] Beneficial effects: The structure of the second temperature control valve is basically the same as that of the first temperature control valve, the only difference being that the second valve body has a third through hole. The third air outlet channel is connected to the core cavity of the second electromagnetic switch valve through the third through hole. Therefore, the specific structure of the second temperature control valve will not be described in detail here. By setting multiple first temperature control valves and multiple second temperature control valves, different temperature control needs can be met or different working scenarios can be adapted. More precise and flexible temperature control can be achieved through the coordinated work of multiple temperature control valves.

[0022] By coordinating the first and second temperature control valves, when the gas baking equipment is working, the amount of gas supplied to the gas-consuming end is increased by opening the first and second through holes of the first temperature control valve and the third through hole of the second temperature control valve, thereby increasing the combustion effect at the gas-consuming end and rapidly raising the temperature inside the gas baking equipment. When the temperature inside the gas baking equipment meets the usage requirements, the first through hole of the first temperature control valve can be closed according to the first electromagnetic switch valve core of the first electromagnetic switch valve core, and the third through hole of the second temperature control valve can be closed according to the second electromagnetic switch valve core of the second electromagnetic switch valve core, thereby reducing the amount of gas at the gas-consuming end. The gas-consuming end burns in a low flame state, thereby maintaining a relatively constant temperature inside the gas baking equipment and realizing the temperature control function of the gas baking equipment.

[0023] By combining multiple first and second temperature control valves, the combustion state at the gas-consuming end can be manually controlled by the stopcock valve core, or automatically controlled by the electromagnetic switch valve core. This facilitates temperature control within the gas-fired baking equipment and can meet the temperature control requirements of different application scenarios. The gas flow rate at the gas-consuming end is adjusted via the first, second, and third through-holes, preventing excessively high temperatures due to excessive gas flow or excessively low temperatures due to rapid temperature loss, thus effectively improving the temperature control accuracy of the gas-fired baking equipment.

[0024] On the other hand, the present invention also provides a gas-fired baking apparatus, comprising:

[0025] Equipment body;

[0026] A control panel is installed on the main body of the device.

[0027] An external power source, electrically connected to the control panel, is used to provide power to the control panel;

[0028] Multiple burners are disposed at the bottom of the main body of the device;

[0029] As described above, in the temperature control valve body assembly, the first temperature control valve and the second temperature control valve are respectively connected to the burner one-to-one, and the control panel is electrically connected to the electromagnetic switch valve core in the temperature control valve body assembly.

[0030] An air intake pipe is provided with at least one first temperature control valve and at least one second temperature control valve.

[0031] Beneficial effects: By installing a control panel on the main body of the equipment, users can adjust the working status of the gas-fired baking equipment and view its operating conditions. An external power supply is electrically connected to the control panel, providing power to ensure its proper functioning and enabling the normal operation of various electronic components, sensors, and controllers, thereby achieving automated control of the gas-fired baking equipment.

[0032] By placing multiple burners at the bottom of the main body of the equipment, heat can be evenly transferred upwards to heat the baking space inside the gas-fired baking equipment. By using multiple burners, different heat outputs can be provided according to baking needs. By controlling the on / off state and combustion intensity of different burners, the temperature distribution and heating rate within the gas-fired baking equipment can be flexibly adjusted to meet various baking process requirements.

[0033] The first and second temperature control valves in the temperature control valve assembly are connected one-to-one with the burners, so that each burner has a corresponding temperature control valve to precisely control its gas supply. The temperature control valves can adjust the gas flow rate according to the temperature inside the gas baking equipment, thereby controlling the combustion intensity of the burners and achieving precise regulation of the internal temperature of the equipment.

[0034] The control panel is electrically connected to the solenoid valve core in the temperature control valve assembly, allowing the control panel to indirectly control the gas supply to the burner by controlling the opening and closing of the solenoid valve core. When the control panel receives temperature information from the temperature sensor and determines that the heat needs to be increased or decreased, it sends a corresponding electrical signal to the solenoid valve core. The solenoid valve core then controls the opening and closing of the first through-hole according to the signal, thereby adjusting the working state of the burner to achieve automatic control of the internal temperature of the gas-fired heating equipment.

[0035] By installing at least one first temperature control valve and at least one second temperature control valve on the air intake pipe, the temperature inside the gas baking equipment can be rapidly increased according to the cooperation between the first temperature control valve and the second temperature control valve. After the temperature meets the preset temperature, the first through hole in the first temperature control valve and the second temperature control valve is closed to control the burner to burn in a low flame state, thereby ensuring that the temperature inside the gas baking equipment is relatively stable.

[0036] In one embodiment, a temperature sensor is also included, electrically connected to the control panel, for real-time detection of the temperature inside the gas-fired baking equipment.

[0037] Beneficial effects: By setting up a temperature sensor, which can be electrically connected to the control panel, the temperature inside the gas baking equipment can be detected in real time, making it convenient to further adjust the working status of the gas baking equipment based on the temperature detected by the temperature sensor.

[0038] In one embodiment, the control panel is provided with multiple buttons, a display unit, and probe holes;

[0039] The multiple buttons are used to generate control commands, the probe hole is used for a probe to detect the temperature of the object being heated inside the gas baking equipment, and the display unit is used to display the temperature inside the gas baking equipment and the temperature of the object being heated.

[0040] Beneficial effects: By setting multiple buttons on the control panel, different control commands can be generated based on these buttons to facilitate the control of the gas-fired baking equipment's operating status. The probe holes on the control panel allow for easy detection of the temperature of the object being heated inside the equipment, thus facilitating the assessment of the object's baking status. The display unit on the control panel provides a clear view of the internal temperature of the gas-fired baking equipment and the temperature of the heated object, enabling adjustments to the equipment's operating status.

[0041] In one embodiment, a ignition channel is further included, disposed between two adjacent burners and connected to the two adjacent burners respectively.

[0042] Beneficial effects: By setting up a ignition channel between two adjacent burners and connecting the ignition channel to the burners, when it is necessary to quickly increase the temperature inside the gas baking equipment, the third through hole is opened by controlling the core of the second electromagnetic switch valve to introduce gas into the non-working burner. Then, the non-working burner is ignited through the ignition channel, causing it to enter the combustion state, thereby quickly increasing the temperature inside the gas baking equipment.

[0043] In one embodiment, a light-emitting knob is further included, which is connected to the first valve stem and the second valve stem respectively. The light-emitting knob is provided with a light-emitting element of at least one color.

[0044] The luminous knob light switch is electrically connected to the luminous knob, the external power supply, and the control panel, respectively, and is used to control the on / off state of the light-emitting element on the luminous knob.

[0045] Beneficial effects: By fixing the luminous knob to the first and second valve stems, rotating the knob rotates both valve stems, thereby adjusting the valve cores of the first and second stopcocks to regulate the amount of gas entering the thermostatic valve. The knob also features a light-emitting element that changes color or state according to the thermostatic valve's operating status. The knob is electrically connected to a light switch, which controls the illumination of the light-emitting element. The light switch is also electrically connected to an external power supply and control panel, providing power to the element via the external power source. The control panel can control the element's illumination via commands from the light switch. The presence of at least one color light-emitting element on the knob allows the user to easily determine the thermostatic valve's operating status, and also enhances the aesthetics.

[0046] In one embodiment, the external power source is a battery pack formed by connecting multiple batteries in series or in parallel.

[0047] Beneficial effects: By connecting multiple batteries in series or parallel to form a battery pack, the battery pack provides a 3V voltage to the control panel, avoiding excessive voltage and preventing voltage leakage.

[0048] On the other hand, the present invention also provides a control method for a gas-fired baking device, applied to the gas-fired baking device as described above, the method comprising:

[0049] Obtain the preset temperature of the gas-fired baking equipment;

[0050] When the gas baking equipment is in temperature control mode, in response to the current temperature inside the gas baking equipment meeting the preset temperature, the electromagnetic switch valve core is controlled to close the through hole, so that the burner burns in a low flame state. The temperature control mode is characterized by the current temperature inside the gas baking equipment meeting the preset temperature and being relatively constant. The electromagnetic switch valve core includes a first electromagnetic switch valve core and a second electromagnetic switch valve core, and the through hole includes a first through hole and a third through hole.

[0051] Beneficial effects: By acquiring the preset temperature of the gas baking equipment and comparing the current temperature inside the gas baking equipment with the preset temperature when the gas baking equipment is in temperature control mode; when the current temperature inside the gas baking equipment meets the preset temperature, that is, the current temperature inside the gas baking equipment is greater than or equal to the preset temperature, the electromagnetic switch valve core is controlled to work, so that the electromagnetic switch valve core closes the through hole, reducing the amount of gas supplied to the burner, so that the burner burns in a low flame state, thereby controlling the current temperature inside the gas baking equipment to be relatively constant, and the current temperature inside the gas baking equipment can be precisely controlled.

[0052] In one embodiment, controlling the electromagnetic switch valve core to close the through hole in response to the current temperature within the gas-fired baking equipment meeting the preset temperature includes:

[0053] When the preset temperature is greater than the first preset temperature and less than or equal to the second preset temperature, the first temperature control valve is controlled to open the first through hole and the second through hole, and the second preset temperature is greater than the first preset temperature.

[0054] In response to the current temperature within the gas-fired baking equipment meeting the preset temperature, the first electromagnetic switch valve core is controlled to close the first through hole.

[0055] Beneficial effects: When the preset temperature is higher than the first preset temperature but less than or equal to the second preset temperature, the preset temperature is relatively low. When the current temperature inside the gas baking equipment needs to be heated to meet the preset temperature, the first thermostatic valve can be controlled to open the first and second through holes, thereby increasing the amount of gas transmitted to the burner, controlling the burner to burn at a high flame, and rapidly increasing the temperature inside the gas baking equipment. When it is detected that the current temperature inside the gas baking equipment meets the preset temperature, the first electromagnetic switch valve core of the first thermostatic valve is controlled to close the first through hole, leaving only the second through hole open to transmit gas to the burner, so as to control the temperature inside the gas baking equipment to be relatively constant.

[0056] In one embodiment, the step of controlling the electromagnetic switch valve core to close the through hole in response to the current temperature within the gas-fired baking equipment meeting the preset temperature further includes:

[0057] When the preset temperature is greater than the second preset temperature and less than or equal to the third preset temperature, the first temperature control valve is controlled to open the first through hole and the second through hole, and the third preset temperature is greater than the second preset temperature.

[0058] In response to the fact that the current temperature inside the gas baking equipment cannot meet the reserved temperature, the second temperature control valve is controlled to open the third through hole;

[0059] In response to the current temperature within the gas-fired baking equipment meeting the preset temperature, the first electromagnetic switch valve core is controlled to close the first through hole, and the second electromagnetic switch valve core is controlled to close the third through hole.

[0060] Beneficial effects: When the preset temperature is higher than the second preset temperature but less than or equal to the third preset temperature, the preset temperature is relatively high. When the current temperature inside the gas baking equipment needs to be heated to meet the preset temperature, the first thermostatic valve can be controlled to open the first and second through holes, thereby increasing the amount of gas transmitted to the burner and controlling the burner to burn at high flame, rapidly increasing the temperature inside the gas baking equipment. When the preset temperature cannot be met by the burner connected only to the first thermostatic valve, the second thermostatic valve is controlled to open the third through hole, causing the burner connected to the second thermostatic valve to operate. By having multiple burners operate simultaneously, the temperature inside the gas baking equipment is rapidly increased. When it is detected that the current temperature inside the gas baking equipment meets the preset temperature, the first solenoid valve core of the first thermostatic valve is controlled to close the first through hole, and the second solenoid valve core of the second thermostatic valve is controlled to close the third through hole, leaving only the second through hole in the first thermostatic valve to transmit gas to the burner, so as to control the temperature inside the gas baking equipment to be relatively constant.

[0061] In one embodiment, after controlling the electromagnetic switch valve core to close the through hole in response to the current temperature within the gas-fired baking equipment meeting the preset temperature, the method further includes:

[0062] Detect the current temperature inside the gas-fired baking equipment;

[0063] In response to the current temperature inside the gas-fired baking equipment being lower than the predetermined temperature, the electromagnetic switch valve core is controlled to open the through hole, causing the burner to burn in a high-fire state.

[0064] Beneficial effects: After the electromagnetic switch valve core closes the through hole, the current temperature inside the gas baking equipment is detected in real time and compared with the preset temperature. When the current temperature inside the gas baking equipment is lower than the preset temperature, the electromagnetic switch valve core is controlled to open the through hole again, so that the burner burns in a high flame state, and the current temperature inside the gas baking equipment is controlled to meet the preset temperature, thereby meeting the user's needs.

[0065] In one embodiment, the method further includes:

[0066] In response to turning on the gas-fired baking equipment, the gas-fired baking equipment is controlled to enter the grilling mode;

[0067] Generate constant temperature control commands based on the control panel;

[0068] The constant temperature control command is transmitted to the gas baking equipment, and the gas baking equipment is controlled to enter the temperature control mode.

[0069] Beneficial effects: When the gas baking equipment is turned on, it will first enter the grilling mode; if it is necessary to control the gas baking equipment to enter the temperature control mode, a constant temperature control command can be generated by pressing the second button on the control panel; then the constant temperature control command is transmitted to the controller of the gas baking equipment, and the controller controls the gas baking equipment to enter the temperature control mode, so as to control the electromagnetic switch valve core to work, thereby further adjusting the combustion state of the burner.

[0070] In one embodiment, the method further includes:

[0071] When the gas-fired baking equipment is in the grilling mode, the first and second through holes of the first temperature control valve are opened, and the third through hole of the second temperature control valve is opened. The combustion state of the burner is controlled based on the plug valve core, which includes a first plug valve core and a second plug valve core.

[0072] Beneficial effects: When the gas-fired baking equipment is in grilling mode, the electromagnetic switch valve core is not working, and both the first and second through holes of the first temperature control valve are open, while the third through hole of the second temperature control valve is open. If the burner's combustion state needs adjustment, it can be done using the first stopcock valve core. When the first stopcock valve core rotates counterclockwise 90°, the first air inlet corresponds to the first air inlet channel, and the first valve body is in a high-flow state. When the first stopcock valve core rotates counterclockwise 180°, the second air inlet corresponds to the first air inlet channel, and the first valve body is in a low-flow state. Similarly, when the second stopcock valve core rotates counterclockwise 90°, the third air inlet corresponds to the second air inlet channel, and the second valve body is in a high-flow state; when the second stopcock valve core rotates counterclockwise 180°, the fourth air inlet corresponds to the second air inlet channel, and the second valve body is in a low-flow state. The combustion state of the burner is controlled by the rotation angle of the stopcock valve core in the stopcock valve core, which can ensure the normal use of the gas baking equipment when the electromagnetic switch valve core fails.

[0073] In one embodiment, it further includes:

[0074] The current temperature inside the gas-fired baking equipment is acquired in real time, and the trend of temperature change inside the gas-fired baking equipment is analyzed.

[0075] Based on the current temperature change trend within the gas-fired baking equipment, future temperature changes within the gas-fired baking equipment are predicted, and the operation of the electromagnetic switch valve core is controlled in real time.

[0076] Beneficial Effects: The current temperature inside the gas-fired baking equipment is acquired in real time via a temperature sensor. The temperature trend is analyzed based on this data. Furthermore, based on this trend, future temperature changes within the equipment are predicted. If the temperature inside the equipment is lower than the preset temperature in the near future, the electromagnetic switch valve core is activated to open the orifice, altering the burner's combustion state and improving its efficiency to raise the temperature. Conversely, if the temperature is significantly higher than the preset temperature in the near future, the electromagnetic switch valve core closes the orifice, reducing the burner's efficiency and preventing excessive heat from being supplied to the equipment. By predicting future temperature changes and enabling real-time control of the electromagnetic switch valve core, the temperature inside the gas-fired baking equipment can be quickly and stably maintained near the preset temperature, improving temperature control accuracy and equipment stability, and meeting the need for precise temperature control.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0098] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0099] According to embodiments of the present invention, such as Figures 1 to 3As shown, a temperature control valve body assembly is provided for use in a gas-fired baking equipment, comprising: a plurality of first temperature control valves 10, each first temperature control valve 10 including a first valve body 11 and a first plug valve core 12 and a first electromagnetic switch valve core 13 integrated on the first valve body 11; the first valve body 11 is provided with a first air inlet channel 16, a first plug valve core cavity 121, a first electromagnetic switch valve core cavity 131 and a first air outlet channel 14 connected in sequence, and the first valve body 11 is also provided with a first through hole 17. The diameter of the first through hole 17 is larger than that of the second through hole 18. The first air outlet channel 14 is connected to the first electromagnetic switch valve core cavity 131 through the first through hole 17 and the second through hole 18 respectively. The first plug valve core 12 is disposed in the first plug valve core cavity 121 and is used to open or close the first air inlet channel 16 and the first plug valve core cavity 121. The first electromagnetic switch valve core cavity 131 is provided with a first electromagnetic switch valve core 132, which is used to open or close the first through hole 17.

[0100] In this embodiment, the first temperature control valve 10 includes a first valve body 11. The first valve body 11 provides a platform for the installation and support of other components and allows the gas to flow within the first valve body 11 along a predetermined path. For example, the first valve body 11 is sequentially connected to a first air inlet channel 16, a first stopcock valve core cavity 121, a first electromagnetic switch valve core cavity 131, and a first air outlet channel 14. After the gas enters the first stopcock valve core cavity 121 through the first air inlet, it can be sequentially transmitted to the first electromagnetic switch valve core cavity 131 and the first air outlet channel 14, and finally transmitted to the gas-consuming end. A first stopcock valve core 12 is provided on the first valve body 11 and is located within the first stopcock valve core cavity 121. The first stopcock valve core 12 can be manually opened or closed between the first air inlet channel 16 and the first stopcock valve core cavity 121. By using the first stopcock valve core 12, the amount of gas entering the first valve body 11 can be manually controlled. The first valve body 11 is also provided with a first electromagnetic switch valve core 13, and the first electromagnetic switch valve core 13 has a first electromagnetic switch valve core 132. The first electromagnetic switch valve core 132 is disposed in the first electromagnetic switch valve core cavity 131 and is used to open or close the first through hole 17.

[0101] Furthermore, the first valve body 11 is also provided with a first through hole 17 and a second through hole 18, and the diameter of the first through hole 17 is larger than the diameter of the second through hole 18; the first gas outlet channel 14 is connected to the first electromagnetic switch valve core cavity 131 through the first through hole 17 and the second through hole 18 respectively. When the gas baking equipment is in the grilling mode and requires a large gas consumption, the valve core 132 of the first electromagnetic switch valve is controlled to open the first through hole 17, so that the gas is quickly transmitted from the first through hole 17 and the second through hole 18 to the first gas outlet channel 14 to meet the gas flow requirements of the gas baking equipment. When the gas baking equipment is in the temperature control mode, more precise control of the gas is required. At this time, the valve core 132 of the first electromagnetic switch valve closes the first through hole 17, and the gas is transmitted to the first gas outlet channel 14 through the smaller diameter second through hole 18. The gas end is in a low flame combustion state, thereby ensuring that the temperature inside the gas baking equipment is relatively constant. By limiting the diameter of the first through hole 17 and the second through hole 18, the combustion state of the gas baking equipment can be controlled more precisely.

[0102] When the gas baking equipment is working, the amount of gas supplied to the gas-consuming end is increased by opening the first through hole 17 and the second through hole 18 of the first temperature control valve 10, thereby increasing the combustion effect at the gas-consuming end and quickly raising the temperature inside the gas baking equipment. When the temperature inside the gas baking equipment meets the usage requirements, the first through hole 17 of the first temperature control valve 10 can be closed according to the first electromagnetic switch valve core 132 of the first electromagnetic switch valve core 13, thereby transmitting gas to the gas-consuming end through the second through hole 18 to reduce the amount of gas at the gas-consuming end. The gas-consuming end burns in a low flame state, thereby maintaining a relatively constant temperature inside the gas baking equipment and realizing the temperature control function of the gas baking equipment.

[0103] The first temperature control valve 10 of the present invention can manually control the combustion state of the gas end according to the first stop valve core 12, and can also automatically control the combustion state of the gas end according to the first electromagnetic switch valve core 13, so as to realize the switching of large and small flames of the gas baking equipment in temperature control mode. Moreover, it is simpler in structure and lower in cost than gas ovens using proportional valves.

[0104] In one embodiment, the first electromagnetic switch valve core 13 further includes a first elastic element 134, which is sleeved on the first electromagnetic switch valve core 132; the first electromagnetic switch valve core 132 is provided with a first sealing gasket 133, and the first elastic element 134 is connected to the first sealing gasket 133.

[0105] In this embodiment, a first sealing gasket 133 is provided on the first electromagnetic switch valve core 132 near the first through hole 17. The diameter of the first sealing gasket 133 is larger than the diameter of the first through hole 17. A first elastic member 134 is sleeved on the first electromagnetic switch valve core 132, and one end of the first elastic member 134 is connected to the first sealing gasket 133, and the other end is connected to the limiting step on the first electromagnetic switch valve core 13. When the first electromagnetic switch valve core 13 is closed, when it is necessary to close the first through hole 17, the elastic force of the first elastic member 134 can be used to press against the first sealing gasket 133, thereby blocking the first through hole 17 without continuously supplying power to the first electromagnetic switch valve core 13. When the first electromagnetic switch valve core 13 is open, after the first electromagnetic switch valve core 13 is working, it relies on the magnet to hold the first sealing gasket 133, thereby blocking the first through hole 17. It is also not necessary to continuously supply power to the first electromagnetic switch valve core 13, which can effectively save energy and extend the service life of the external power supply 103.

[0106] In one embodiment, the first plug valve core 12 further includes a first plug valve core 123 and a first valve stem 124. The first valve stem 124 is connected to the first plug valve core 123. The first plug valve core 123 is disposed in the first plug valve core cavity 121. The first plug valve core 123 is provided with a first air inlet and a second air inlet 125. The diameter of the first air inlet is larger than the diameter of the second air inlet 125.

[0107] In this embodiment, a first plug valve core 123 is provided in the first plug valve core cavity 121, and the first plug valve core 123 is connected to the first valve stem 124; by driving the first valve stem 124 to drive the first plug valve core 123 to rotate, the on / off state of the gas and the amount of gas are controlled. The first stopcock valve core 123 is provided with a first air inlet and a second air inlet 125, wherein the diameter of the first air inlet is larger than the diameter of the second air inlet 125. When the first air inlet is opposite to the first air intake channel 16, the first stopcock valve core cavity 121 is connected to the first air intake channel 16, and a large amount of gas flows into the first stopcock valve core cavity 121. The first temperature control valve 10 is in a high flow rate state, and the gas consumption end is in a high-fire combustion state. When the second air inlet 125 is opposite to the first air intake channel 16, the first stopcock valve core cavity 121 is connected to the first air intake channel 16, and a small amount of gas flows into the first stopcock valve core cavity 121. The first temperature control valve 10 is in a low flow rate state, and the gas consumption end is in a low-fire combustion state. If neither the first air inlet nor the second air inlet 125 is opposite to the first air intake channel 16, the first stopcock valve core 123 blocks the connection between the first stopcock valve core cavity 121 and the first air intake channel 16. By manually controlling the combustion state of the gas baking equipment through the first stop valve core 12, the normal operation of the gas baking equipment can be ensured in case the first electromagnetic switch valve core 13 fails.

[0108] In one embodiment, a first nozzle 15 is further included, which is connected to the first gas outlet channel 14 and the gas-consuming end. Gas flows through the first gas outlet channel 14 to the first nozzle 15, and is then transmitted to the gas-consuming end through the first nozzle 15, ensuring that the gas-consuming end can be supplied normally.

[0109] like Figure 4 As shown, in one embodiment, a plurality of second temperature control valves 20 are also included. Each second temperature control valve 20 includes a second valve body 21 and a second plug valve core 22 and a second electromagnetic switch valve core 23 integrated on the second valve body 21. The second valve body 21 is provided with a second air inlet channel 26, a second plug valve core cavity 221, a second electromagnetic switch valve core cavity 231 and a third air outlet channel 24 connected in sequence. The second valve body 21 is also provided with a third through hole 27. The third air outlet channel 24 is connected to the second electromagnetic switch valve core cavity 231 through the third through hole 27. The second plug valve core 22 is disposed in the second plug valve core cavity 221 and is used to open or close the second air inlet channel 26 and the second plug valve core cavity 221. The second electromagnetic switch valve core cavity 231 is provided with a second electromagnetic switch valve core 232, which is used to open or close the third through hole 27.

[0110] In this embodiment, the structure of the second temperature control valve 20 is basically the same as that of the first temperature control valve 10. The second electromagnetic switch valve core 23 further includes a second elastic element 234, which is sleeved on the second electromagnetic switch valve core 232. The second electromagnetic switch valve core 232 is provided with a second sealing gasket 233, and the second elastic element 234 is connected to the second sealing gasket 233. The second plug valve core 22 further includes a second plug valve core 223 and a second valve stem 224. The second valve stem 224 is connected to the second plug valve core 223, and the second plug valve core 223 is disposed in the second plug valve core cavity 221. The second plug valve core 223 is provided with a third air inlet and a fourth air inlet 225, and the diameter of the third air inlet is larger than the diameter of the fourth air inlet 225. The second valve body 21 is also provided with a second air inlet channel 26, which is connected to the second plug valve core cavity 221 and the air inlet pipe 106 respectively. The second nozzle 25 is connected to the third gas outlet channel 24 and the gas user end. Gas flows through the third gas outlet channel 24 to the second nozzle 25, and is then transmitted to the gas user end through the second nozzle 25, ensuring that the gas user end can be supplied normally.

[0111] The difference between the second temperature control valve 20 and the first temperature control valve 10 is that the second valve body 21 is provided with a third through hole 27, and the third air outlet channel 24 is connected to the second electromagnetic switch valve core cavity 231 through the third through hole 27. Therefore, the specific structure of the second temperature control valve 20 will not be described in detail here.

[0112] By setting multiple first temperature control valves 10 and multiple second temperature control valves 20, different temperature control requirements or different working scenarios can be met. More precise and flexible temperature control can be achieved through the coordinated operation of multiple temperature control valves. Through the cooperation of the first temperature control valves 10 and the second temperature control valves 20, when the gas baking equipment is working, the first through-hole 17 and second through-hole 18 of the first temperature control valve 10 and the third through-hole 27 of the second temperature control valve 20 are opened, increasing the amount of gas supplied to the gas-consuming end, thereby increasing the combustion effect at the gas-consuming end and quickly raising the temperature inside the gas baking equipment. When the temperature inside the gas baking equipment meets the usage requirements, the first through-hole 17 of the first temperature control valve 10 can be closed according to the first electromagnetic switch valve core 132 of the first electromagnetic switch valve core 13, and the third through-hole 27 of the second temperature control valve 20 can be closed according to the second electromagnetic switch valve core 232 of the second electromagnetic switch valve core 23, thereby reducing the amount of gas at the gas-consuming end. The gas-consuming end burns in a low-flame state, thus maintaining a relatively constant temperature inside the gas baking equipment, achieving the temperature control function of the gas baking equipment.

[0113] By combining multiple first temperature control valves 10 and multiple second temperature control valves 20, the combustion state at the gas-consuming end can be manually controlled by the stopcock valve core, or automatically controlled by the electromagnetic switch valve core. This facilitates temperature control within the gas-fired baking equipment and can meet the temperature control requirements of different application scenarios. The gas flow rate at the gas-consuming end is adjusted through the first through-hole 17, the second through-hole 18, and the third through-hole 27, preventing excessively high temperatures due to excessive gas flow or excessively low temperatures due to rapid temperature loss. This effectively improves the temperature control accuracy of the gas-fired baking equipment.

[0114] On the other hand, such as Figures 5 to 10 As shown, this embodiment of the invention also provides a gas-fired baking device, including: a main body 100; a control panel 101 mounted on the main body 100; an external power supply 103 electrically connected to the control panel 101 for providing power to the control panel 101; a plurality of burners 1012 disposed at the bottom of the main body 100; a temperature control valve assembly, wherein a first temperature control valve 10 and a second temperature control valve 20 are respectively connected to the burners 1012 in a one-to-one correspondence, and the control panel 101 is electrically connected to the electromagnetic switch valve core in the temperature control valve assembly; and an air inlet pipe 106, wherein at least one first temperature control valve 10 and at least one second temperature control valve 20 are provided on the air inlet pipe 106.

[0115] In this embodiment, by installing a control panel 101 on the main body 100, the user can adjust the working status of the gas baking equipment according to the control panel 101 and view the working status of the gas baking equipment. An external power supply 103 is electrically connected to the control panel 101 to provide power to the control panel 101, ensuring that the control panel 101 can work normally and that various electronic components, sensors, and controllers can operate normally, thereby realizing the automated control of the gas baking equipment.

[0116] By placing multiple burners 1012 at the bottom of the main body 100 of the equipment, heat can be evenly transferred upwards to heat the baking space inside the gas-fired baking equipment. By setting multiple burners 1012, different heat outputs can be provided according to baking requirements. By controlling the opening or closing of different burners 1012 and the combustion intensity, the temperature distribution and heating rate inside the gas-fired baking equipment can be flexibly adjusted to meet different baking process requirements.

[0117] The first temperature control valve 10 and the second temperature control valve 20 in the temperature control valve body assembly are connected one-to-one with the burners 1012, so that each burner 1012 has a corresponding temperature control valve to precisely control its gas supply. The temperature control valve can adjust the gas flow rate according to the temperature inside the gas baking equipment, thereby controlling the combustion intensity of the burner 1012 and achieving precise regulation of the internal temperature of the equipment.

[0118] The control panel 101 is electrically connected to the solenoid valve core in the temperature control valve assembly, enabling the control panel 101 to indirectly control the gas supply to the burner 1012 by controlling the opening and closing of the solenoid valve core. When the control panel 101 receives temperature information from the temperature sensor 104 and determines that the heat needs to be increased or decreased, it sends a corresponding electrical signal to the solenoid valve core. The solenoid valve core controls the opening and closing of the first through hole 17 according to the signal, thereby adjusting the working state of the burner 1012 to achieve automatic control of the internal temperature of the gas baking equipment.

[0119] By setting at least one first temperature control valve 10 and at least one second temperature control valve 20 on the air inlet pipe 106, the temperature inside the gas baking equipment is rapidly increased according to the cooperation of the first temperature control valve 10 and the second temperature control valve 20. After the temperature meets the preset temperature, the first through hole 17 in the first temperature control valve 10 and the second temperature control valve 20 is closed to control the burner 1012 to burn in a low flame state, thereby ensuring that the temperature inside the gas baking equipment is relatively stable.

[0120] Furthermore, the first temperature control valve 10 and the second temperature control valve 20 can be arranged alternately on the air intake pipe 106; or, the second temperature control valve 20 can be arranged between two first temperature control valves 10; or, the first temperature control valve 10 can be arranged between two second temperature control valves 20. The specific arrangement can be customized according to actual usage requirements.

[0121] like Figure 7 As shown, in one embodiment, a temperature sensor 104 is also included, which is electrically connected to the control panel 101 for real-time detection of the temperature inside the gas baking equipment.

[0122] In this embodiment, by setting a temperature sensor 104, which can be electrically connected to the control panel 101, the temperature inside the gas baking equipment can be detected in real time, which is convenient for further adjustment of the working status of the gas baking equipment based on the temperature detected by the temperature sensor 104.

[0123] like Figure 8 As shown, in one embodiment, the control panel 101 is provided with multiple buttons, a display unit 1005 and a probe hole 1006; the multiple buttons are used to generate control commands, the probe hole 1006 is used for the probe to detect the temperature of the heated object in the gas baking equipment, and the display unit 1005 is used to display the temperature in the gas baking equipment and the temperature of the heated object.

[0124] In this embodiment, multiple buttons are set on the control panel 101, and different control commands are generated based on these buttons to control the working state of the gas baking equipment. The probe hole 1006 on the control panel 101 allows a probe to detect the temperature of the object being heated inside the gas baking equipment, thus facilitating the determination of the object's baking status based on its temperature. The display unit 1005 on the control panel 101 provides a clear view of the temperature inside the gas baking equipment and the temperature of the heated object, enabling adjustments to the working state of the gas baking equipment.

[0125] Furthermore, the buttons include a first button 1001 for controlling the gas baking equipment to enter the grilling mode; a second button 1002 for controlling the gas baking equipment to enter the temperature control mode; a third button 1003 for adjusting the preset temperature of the gas baking equipment; a fourth button 1004 for adjusting the temperature display mode on the display unit 1005, allowing the temperature display mode to switch between Fahrenheit and Celsius; and a power switch 1007 for controlling the gas baking equipment to turn on or off.

[0126] In one embodiment, a flame transmission channel 105 is also included, which is disposed between two adjacent burners 1012 and is connected to the two adjacent burners 1012 respectively.

[0127] In this embodiment, by setting a flare transmission channel 105 between two adjacent burners 1012 and connecting the flare transmission channel 105 to the burners 1012, when it is necessary to quickly increase the temperature inside the gas baking equipment, the third through hole 27 is opened by controlling the second electromagnetic switch valve core 23 to introduce gas into the non-working burner 1012, and then the non-working burner 1012 is ignited through the flare transmission channel 105 to put it into the combustion state, thereby quickly increasing the temperature inside the gas baking equipment.

[0128] Furthermore, when the working mode of the gas baking equipment is switched from temperature control mode to barbecue mode, the second temperature control valve 20 opens the third through hole 27, and gas is filled into the burner 1012 connected to the second temperature control valve 20. At this time, the flame is transmitted from the ignition channel 105 to the burner 1012 that is not in operation, so as to ignite the burner 1012 and put it into the combustion state.

[0129] In one embodiment, it also includes a light-emitting knob 102, which is connected to the first valve stem 124 and the second valve stem 224 respectively. The light-emitting knob 102 is provided with a light-emitting body of at least one color. The light-emitting knob light switch 107 is electrically connected to the light-emitting knob 102, the external power supply 103 and the control panel 101 respectively, and is used to control the on / off state of the light-emitting body on the light-emitting knob 102.

[0130] In this embodiment, by fixing the luminous knob 102 to the first valve stem 124 and the second valve stem 224, rotating the luminous knob 102 rotates the first valve stem 124 and the second valve stem 224, thereby rotating the first stop valve core 123 and the second stop valve core 223 to adjust the amount of gas entering the thermostatic valve. A light-emitting element is also provided on the luminous knob 102, which can change its color or state according to the working state of the thermostatic valve. The luminous knob 102 is electrically connected to a luminous knob light switch 107, which controls the on / off state of the light-emitting element on the luminous knob 102. The luminous knob light switch 107 is also electrically connected to an external power supply 103 and a control panel 101, with the external power supply 103 providing power to the light-emitting element on the luminous knob 102, and the control panel 101 controlling the on / off state of the light-emitting element through commands issued by the luminous knob light switch 107. By providing a light-emitting element of at least one color on the luminous knob 102, the operating status of the luminous knob 102 can be determined by the light-emitting element, making it easier for users to judge the operating status of the temperature control valve, and it is also more aesthetically pleasing. For example, when the light-emitting element is white, it indicates that the temperature control valve is not working; when the light-emitting element is red, it indicates that the temperature control valve is working.

[0131] In one embodiment, the external power source 103 is a battery pack formed by connecting multiple batteries in series or in parallel.

[0132] In this embodiment, multiple batteries are connected in series or parallel to form a battery pack. The battery pack provides a 3V voltage to the control panel 101 to avoid excessive voltage and prevent voltage leakage. Furthermore, multiple batteries can be connected in series to form two battery packs, and these two battery packs can be connected in parallel to form an external power supply 103. The specific battery connection method can be set according to actual usage requirements and is not specifically limited.

[0133] In one embodiment, the device further includes an ignition button 109, an igniter 1091, and an ignition connection wire 1092. The ignition button 109 is electrically connected to the igniter 1091, and the ignition connection wire 1092 is connected to the igniter 1091. The ignition connection wire 1092 is connected to an ignition needle 108, which is located on one side of the burner 1012. The igniter 1091 is powered by a battery. When the ignition button 109 is pressed, the igniter 1091 receives a signal and begins to discharge. The signal is transmitted to the ignition needle 108 through the ignition connection wire 1092 to complete the discharge and ignite the burner 1012.

[0134] In one embodiment, the air inlet pipe 106 is also connected to a side stove head 1010 and a pressure relief valve 1011.

[0135] It is understood that the gas-fired baking equipment provided by the present invention may be, but is not limited to, a gas-fired oven.

[0136] On the other hand, such as Figure 11 As shown, this embodiment of the invention also provides a control method for a gas-fired baking device, applied to a gas-fired baking device, comprising the following steps:

[0137] Step S100: Obtain the preset temperature of the gas-fired baking equipment;

[0138] Step S200: When the gas baking equipment is in temperature control mode, in response to the current temperature in the gas baking equipment meeting the preset temperature, the electromagnetic switch valve core is controlled to close the through hole, so that the burner 1012 burns in a low flame state. The temperature control mode is characterized by the current temperature in the gas baking equipment meeting the preset temperature and being relatively constant. The electromagnetic switch valve core includes a first electromagnetic switch valve core 13 and a second electromagnetic switch valve core 23, and the through hole includes a first through hole 17 and a third through hole 27.

[0139] In this embodiment, the preset temperature of the gas baking equipment is obtained, and when the gas baking equipment is in temperature control mode, the current temperature inside the gas baking equipment is compared with the preset temperature. When the current temperature inside the gas baking equipment meets the preset temperature, that is, the current temperature inside the gas baking equipment is greater than or equal to the preset temperature, the core of the electromagnetic switch valve is controlled to work, so that the core of the electromagnetic switch valve closes the through hole, reducing the amount of gas supplied to the burner 1012, so that the burner 1012 burns in a low flame state, thereby controlling the current temperature inside the gas baking equipment to be relatively constant, and the current temperature inside the gas baking equipment can be precisely controlled.

[0140] like Figure 12 As shown, in one embodiment, step S200 includes the following steps:

[0141] Step S210: When the preset temperature is greater than the first preset temperature and less than or equal to the second preset temperature, control the first temperature control valve 10 to open the first through hole 17 and the second through hole 18, and the second preset temperature is greater than the first preset temperature.

[0142] Step S210: In response to the current temperature in the gas baking equipment meeting the preset temperature, control the first electromagnetic switch valve core 13 to close the first through hole 17.

[0143] In this embodiment, when the preset temperature is greater than the first preset temperature but less than or equal to the second preset temperature, the preset temperature is relatively low. When the current temperature inside the gas baking equipment needs to be heated to meet the preset temperature, the first temperature control valve 10 can be controlled to open the first through hole 17 and the second through hole 18, thereby increasing the amount of gas transmitted to the burner 1012, controlling the burner 1012 to burn in a high-fire state, and rapidly increasing the temperature inside the gas baking equipment. When it is detected that the current temperature inside the gas baking equipment meets the preset temperature, the first electromagnetic switch valve core 13 of the first temperature control valve 10 is controlled to close the first through hole 17, leaving only the second through hole 18 open for gas transmission to the burner 1012, so as to control the temperature inside the gas baking equipment to be relatively constant.

[0144] like Figure 13 As shown, in one embodiment, step S200 further includes the following steps:

[0145] Step S230: When the preset temperature is greater than the second preset temperature and less than or equal to the third preset temperature, control the first temperature control valve 10 to open the first through hole 17 and the second through hole 18, and the third preset temperature is greater than the second preset temperature.

[0146] Step S240: In response to the current temperature in the gas baking equipment not meeting the preset temperature, control the second temperature control valve 20 to open the third through hole 27;

[0147] Step S250: In response to the current temperature in the gas baking equipment meeting the preset temperature, control the first electromagnetic switch valve core 13 to close the first through hole 17 and the second electromagnetic switch valve core 23 to close the third through hole 27.

[0148] In this embodiment, the preset temperature is relatively high when it is greater than the second preset temperature and less than or equal to the third preset temperature. When the current temperature in the gas baking equipment needs to be heated to meet the preset temperature, the first temperature control valve 10 can be controlled to open the first through-hole 17 and the second through-hole 18, thereby increasing the amount of gas transmitted to the burner 1012, controlling the burner 1012 to burn in a high-fire state, and rapidly increasing the temperature inside the gas baking equipment. When the preset temperature cannot be met by the burner 1012 connected only to the first temperature control valve 10, the second temperature control valve 20 is controlled to open the third through-hole 27, causing the burner 1012 connected to the second temperature control valve 20 to work, and the temperature inside the gas baking equipment is rapidly increased by having multiple burners 1012 work simultaneously. When the current temperature inside the gas baking equipment is detected to meet the preset temperature, the first electromagnetic switch valve core 13 of the first temperature control valve 10 is controlled to close the first through hole 17 and the second electromagnetic switch valve core of the second temperature control valve 20 is controlled to close the third through hole 27. At this time, the burner 1012 connected to the second temperature control valve 20 does not work, and only the second through hole 18 in the first temperature control valve 10 is kept open to transmit gas to the burner 1012, so that the burner 1012 connected to the first temperature control valve 10 burns in a low flame state, so as to control the temperature inside the gas baking equipment to be relatively constant.

[0149] like Figure 14 As shown, in one embodiment, the following step is included after step S200:

[0150] Step S300: Detect the current temperature inside the gas-fired baking equipment;

[0151] Step S400: In response to the current temperature in the gas baking equipment being lower than the preset temperature, the electromagnetic switch valve core is controlled to open the through hole, so that the burner 1012 burns in a high-fire state.

[0152] In this embodiment, after the electromagnetic switch valve core closes the through hole, the current temperature inside the gas baking equipment is detected in real time, and the current temperature inside the gas baking equipment is compared with the preset temperature. When the current temperature inside the gas baking equipment is lower than the preset temperature, the electromagnetic switch valve core is controlled to open the through hole again, so that the burner 1012 burns in a high flame state, and the current temperature inside the gas baking equipment is controlled to meet the preset temperature, thereby meeting the user's usage needs.

[0153] like Figure 15 As shown, in one embodiment, the following steps are also included:

[0154] Step S101: In response to turning on the gas baking equipment, control the gas baking equipment to enter the grilling mode;

[0155] Step S102: Generate a constant temperature control command based on the control panel 101;

[0156] Step S103: Transmit the constant temperature control command to the gas baking equipment and control the gas baking equipment to enter the temperature control mode.

[0157] In this embodiment, when the gas baking equipment is turned on, the gas baking equipment will first enter the grilling mode; if it is necessary to control the gas baking equipment to enter the temperature control mode, a constant temperature control command can be generated according to the second button 1002 on the control panel 101; then the constant temperature control command is transmitted to the controller of the gas baking equipment, and the controller controls the gas baking equipment to enter the temperature control mode, so as to control the electromagnetic switch valve core to work, thereby further adjusting the combustion state of the burner 1012.

[0158] In one embodiment, it further includes: when the gas baking device is in the grilling mode, controlling the opening of the first through hole 17 and the second through hole 18 of the first temperature control valve 10 and controlling the opening of the third through hole 27 of the second temperature control valve 20, controlling the combustion state of the burner 1012 based on the plug valve core, the plug valve core including the first plug valve core 12 and the second plug valve core 22.

[0159] In this embodiment, when the gas-fired baking equipment is in grilling mode, the electromagnetic switch valve core is not working, and both the first through hole 17 and the second through hole 18 of the first temperature control valve 10 are open, while the third through hole 27 of the second temperature control valve 20 is open. If it is necessary to adjust the combustion state of the burner 1012 at this time, it can be adjusted according to the first stopcock valve core 12. When the first stopcock valve core 123 rotates counterclockwise 90°, the first air inlet corresponds to the first air inlet channel 16, and the first valve body 11 is in a high-flow state. When the first stopcock valve core 123 rotates counterclockwise 180°, the second air inlet 125 corresponds to the first air inlet channel 16, and the first valve body 11 is in a low-flow state. Similarly, when the second stopcock valve core 223 rotates counterclockwise by 90°, the third air inlet corresponds to the second air inlet channel 26, and the second valve body 21 is in a high-flow state; when the second stopcock valve core 223 rotates counterclockwise by 180°, the fourth air inlet 225 corresponds to the second air inlet channel 26, and the second valve body 21 is in a low-flow state. By controlling the combustion state of the burner 1012 according to the rotation angle of the stopcock valve core, the normal operation of the gas-fired baking equipment can be ensured even if the electromagnetic switch valve core fails.

[0160] In one embodiment, the method further includes: acquiring the current temperature inside the gas baking equipment in real time and analyzing the current temperature change trend inside the gas baking equipment; predicting future temperature changes inside the gas baking equipment based on the current temperature change trend inside the gas baking equipment, and controlling the operation of the electromagnetic switch valve core in real time.

[0161] In this embodiment, the current temperature inside the gas baking equipment is acquired in real time by temperature sensor 104, and the trend of temperature change inside the gas baking equipment is analyzed based on the acquired temperature. Specifically, a PID algorithm can be used to analyze the trend of temperature change inside the gas baking equipment. Furthermore, based on the trend of temperature change inside the gas baking equipment, future temperature changes inside the gas baking equipment are predicted. If the temperature inside the gas baking equipment is lower than the preset temperature in the future, the electromagnetic switch valve core is controlled to operate, opening the through hole and changing the combustion state of burner 1012 to improve the combustion efficiency of burner 1012 and thus heat the current temperature inside the gas baking equipment. If the temperature inside the gas baking equipment is much higher than the preset temperature in the future, the electromagnetic switch valve core is controlled to close the through hole, changing the combustion state of burner 1012 to reduce the combustion efficiency of burner 1012 and avoid providing excessive heat to the gas baking equipment. By predicting future temperature changes, real-time control of the electromagnetic switch valve core is achieved, enabling the temperature inside the gas baking equipment to be quickly and stably maintained near the preset temperature, improving the accuracy of temperature control and the stability of the gas baking equipment, and meeting the need for precise temperature control inside the gas baking equipment.
