Description

Technical Field

[0001] The present invention relates to the technical field of gas baking equipment, and in particular to a temperature control valve body component, gas baking equipment and a control method thereof. Background Art

[0002] At present, gas baking equipment such as gas ovens, the gas ovens in the related technology realize the temperature control function including controlling the gas flow of the valve body through the principle of thermal expansion and contraction of the liquid inside the liquid expansion probe, but this method has a single function and poor temperature control accuracy; the gas oven that realizes temperature control by using a proportional valve in combination with a control algorithm has a complex structure, is expensive, and has the risk of voltage leakage, and the proportional valve realizes fire control by adjusting the current size. The proportional valve has poor stability under high temperature conditions, which may affect the normal use of the gas oven. Summary of the invention

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

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

[0005] A temperature control valve body assembly, applied to gas baking equipment, comprising:

[0006] A plurality of first temperature control valves, each of which comprises 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 passage, a first plug valve core chamber, a first electromagnetic switch valve core chamber and a first air outlet passage which are 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 passage is connected with the first electromagnetic switch valve core chamber through the first through hole and the second through hole respectively.

[0008] The first plug valve core is arranged in the first plug valve core cavity and is used to connect or block the first air inlet channel and the first plug valve core cavity. The first electromagnetic switch valve core is provided with a first electromagnetic switch valve core in the first electromagnetic switch valve core cavity and is used to open or close the first through hole.

[0009] Beneficial effects: The first temperature control valve includes a first valve body, which can provide a platform for installation and support of other components, and can make the gas flow in the first valve body according to a predetermined path. For example, the first air inlet channel, the first plug valve core cavity, the first electromagnetic switch valve core cavity and the first air outlet channel are sequentially connected on the first valve body; after the gas enters the first plug 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 transmitted to the gas end. A first plug valve core is provided on the first valve body, and the first plug valve core is arranged in the first plug valve core cavity, and the first air inlet channel and the first plug valve core cavity can be manually connected or blocked. The amount of gas entering the first valve body can be manually controlled by using the first plug valve core. A first electromagnetic switch valve core is also provided on the first valve body, and the first electromagnetic switch valve core has a first electromagnetic switch valve core in the first electromagnetic switch valve core, and the first electromagnetic switch valve core is arranged in the first electromagnetic switch valve core cavity, which is used to open or close the first through hole.

[0010] Furthermore, the first valve body is 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 device is in the barbecue mode and requires a large amount of gas, the first electromagnetic switch valve core 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 demand of the gas baking device. When the gas baking device is in the temperature control mode, the gas needs to be more finely controlled. At this time, the first through hole is closed by the first electromagnetic switch valve core, and the gas is transmitted to the first gas outlet channel through the second through hole with a smaller diameter, and the gas end is in a low-fire combustion state, thereby ensuring that the temperature in the gas baking device is relatively constant. By limiting the diameter size of the first through hole and the second through hole, the combustion state of the gas baking device can be more accurately controlled.

[0011] When the gas baking equipment is working, the first through hole and the second through hole of the first temperature control valve are opened to increase the amount of gas delivered to the gas-using end, thereby increasing the combustion effect of the gas-using end to quickly increase the temperature in the gas baking equipment; when the temperature in the gas baking equipment meets the use requirements, the first through hole of the first temperature control valve can be closed according to the first solenoid switch valve core of the first solenoid switch valve core part, thereby transmitting gas to the gas-using end through the second through hole to reduce the amount of gas at the gas-using end, and the gas-using end burns in a low fire state, thereby keeping the temperature in the gas baking equipment relatively constant, so as to realize the temperature control function of the gas baking equipment.

[0012] The first temperature control valve of the present invention can manually control the combustion state of the gas end according to the first plug 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 fires of the gas baking equipment under the temperature control mode. Moreover, compared with the gas baking oven using a proportional valve, the structure is simpler and the cost is lower.

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

[0014] Beneficial effects: a first sealing gasket is provided on one end of the first solenoid switch valve core close to 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 member is sleeved on the first solenoid switch valve core, and one end of the first elastic member is connected to the first sealing gasket, and the other end is connected to the limiting step on the first solenoid switch valve core; when the first solenoid switch valve core is closed, when the first through hole needs to be closed, the first sealing gasket can be supported by the elastic force of the first elastic member, so that the first sealing gasket blocks the first through hole, and there is no need to continuously power the first solenoid switch valve core; when the first solenoid switch valve core is opened, the first solenoid switch valve core relies on the magnet to absorb the first sealing gasket after working, so as to block the first through hole, and there is no need to continuously power the first solenoid switch valve core, which can effectively save energy consumption and extend the use time of the external power supply.

[0015] In one embodiment, the first plug valve core portion further includes a first plug valve core and a first valve stem, the first valve stem is connected to the first plug valve core, and the first plug valve core is disposed in the first plug valve core cavity;

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

[0017] Beneficial effects: a first plug valve core is arranged in the first plug valve core cavity, and the first plug valve core is connected to the first valve stem; the first valve stem is driven to drive the first plug valve core to rotate, thereby controlling the on and off of the gas and the size of the gas volume. A first air inlet hole and a second air inlet hole are arranged on the first plug valve core, wherein the aperture of the first air inlet hole is larger than the aperture of the second air inlet hole; when the first air inlet hole is opposite to the air inlet channel, the first plug valve core cavity is connected to the first air inlet channel, and the amount of gas flowing into the first plug valve core cavity is large, the first temperature control valve is in a large flow state, and the gas end is in a high-fire burning state; when the second air inlet hole is opposite to the air inlet channel, the first plug valve core cavity is connected to the first air inlet channel, and the amount of gas flowing into the first plug valve core cavity is small, the first temperature control valve is in a small flow state, and the gas end is in a low-fire burning state. If the first air inlet hole and the second air inlet hole are not opposite to the first air inlet channel, the first plug valve core blocks the first plug valve core cavity and the first air inlet channel. The combustion state of the gas baking device is manually controlled by the first plug valve core, and the normal use of the gas baking device can be ensured when the first electromagnetic switch valve core fails.

[0018] In one embodiment, a plurality of second temperature control valves are further included, wherein the second temperature control valves include 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 passage, a second plug valve core chamber, a second electromagnetic switch valve core chamber and a third air outlet passage which are connected in sequence. The second valve body is also provided with a third through hole, and the third air outlet passage is connected with the second electromagnetic switch valve core chamber through the third through hole.

[0020] The second plug valve core is arranged in the second plug valve core cavity and is used to connect or block the second air inlet channel and the second plug valve core cavity. The second electromagnetic switch valve core is provided with a second electromagnetic switch valve core in the second electromagnetic switch valve core cavity and is used to open or close the third through hole.

[0021] Beneficial effect: 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 a third through hole is provided on the second valve body, and the third air outlet channel is connected to the second electromagnetic switch valve core cavity through the third through hole, so the specific structure of the second temperature control valve is not described here. By setting a plurality of first temperature control valves and a plurality of second temperature control valves, different temperature control requirements can be met or different working scenarios can be adapted, and more accurate and flexible temperature control can be achieved through the coordinated work of a plurality of temperature control valves.

[0022] Through the cooperation of the first temperature control valve and the second temperature control valve, when the gas baking equipment is working, the amount of gas delivered to the gas-using end is increased by opening the first through hole and the second through hole of the first temperature control valve and the third through hole of the second temperature control valve, thereby increasing the combustion effect of the gas-using end to quickly increase the temperature in the gas baking equipment; when the temperature in the gas baking equipment meets the use requirements, the first through hole of the first temperature control valve can be closed according to the first solenoid switch valve core of the first solenoid switch valve core part and the third through hole of the second temperature control valve can be closed according to the second solenoid switch valve core of the second solenoid switch valve core part, thereby reducing the amount of gas at the gas-using end, and the gas-using end burns in a low fire state, thereby keeping the temperature in the gas baking equipment relatively constant, so as to realize the temperature control function of the gas baking equipment.

[0023] Through the combination of multiple first temperature control valves and multiple second temperature control valves, the combustion state of the gas end can be manually controlled according to the plug valve core, and the combustion state of the gas end can be automatically controlled according to the electromagnetic switch valve core, so as to control the temperature in the gas baking equipment and meet the requirements of temperature control in different application scenarios. The gas volume of the gas end is adjusted through the first through hole, the second through hole and the third through hole to avoid the situation where the temperature in the gas baking equipment is too high due to excessive gas volume at the gas end, or the temperature in the gas baking equipment is too low due to too fast temperature loss, which can effectively improve the temperature control accuracy of the gas baking equipment.

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

[0025] Equipment body;

[0026] A control panel, mounted on the device body;

[0027] an external power supply, electrically connected to the control panel, and used to provide power to the control panel;

[0028] A plurality of burners are arranged at the bottom of the device body;

[0029] The temperature control valve body assembly as described above, wherein the first temperature control valve and the second temperature control valve are respectively connected to the burner in a one-to-one correspondence, 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 device, the user can adjust the working state of the gas baking device according to the control panel and can view the working status of the gas baking device. The external power supply is electrically connected to the control panel to provide power to the control panel, ensuring that the control panel can work normally, and various electronic components, sensors and controllers can work normally, thereby realizing automatic control of the gas baking device.

[0032] By setting multiple burners at the bottom of the equipment body, heat can be evenly transferred upward to heat the baking space inside the gas baking equipment. By setting multiple burners, different heat outputs can be provided according to baking needs. By controlling the opening or closing of different burners and the combustion intensity, the temperature distribution and heating speed inside the gas baking equipment can be flexibly adjusted to meet different baking process requirements.

[0033] The first temperature control valve and the second temperature control valve in the temperature control valve body assembly are connected to the burners one by one, so that each burner has a corresponding temperature control valve to accurately control its gas supply. The temperature control valve can adjust the flow of gas according to the temperature inside the gas baking equipment, thereby controlling the combustion intensity of the burner and realizing accurate adjustment of the internal temperature of the equipment.

[0034] The control panel is electrically connected to the electromagnetic switch valve core in the temperature control valve body assembly, so that the control panel can indirectly control the gas supply of the burner by controlling the opening and closing of the electromagnetic switch valve core. When the control panel receives the temperature information fed back by the temperature sensor and determines that the heat needs to be increased or decreased, it will send a corresponding electrical signal to the electromagnetic switch valve core, and the electromagnetic switch valve core 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 baking equipment.

[0035] By arranging at least one first temperature control valve and at least one second temperature control valve on the air inlet pipe, the temperature inside the gas baking equipment can be quickly increased according to the cooperation between the first temperature control valve and the second temperature control valve. After the temperature reaches the preset temperature, the first through holes in the first temperature control valve and the second temperature control valve are closed to control the burner to burn in a low fire state, thereby ensuring that the temperature inside the gas baking equipment is relatively stable.

[0036] In one of the embodiments, a temperature sensor is further included, which is electrically connected to the control panel and is used to detect the temperature inside the gas baking device in real time.

[0037] Beneficial effect: By setting up a temperature sensor and electrically connecting it to the control panel, the temperature inside the gas baking device can be detected in real time, which is convenient for further adjusting the working state of the gas baking device according to the temperature detected by the temperature sensor.

[0038] In one of the embodiments, the control panel is provided with a plurality of buttons, a display unit and a probe hole;

[0039] The plurality of buttons are used to generate control instructions respectively, the probe hole is used for a probe to detect the temperature of a heated object in the gas baking device, and the display unit is used to display the temperature in the gas baking device and the temperature of the heated object.

[0040] Beneficial effects: By setting a plurality of buttons on the control panel, different control instructions are generated according to the plurality of buttons, so as to control the working state of the gas baking device. Through the probe hole on the control panel, the probe can detect the temperature of the heated object in the gas baking device through the probe hole, so as to judge the baking state of the object according to the temperature of the heated object. Through the display unit on the control panel, the temperature in the gas baking device can be intuitively determined and the temperature of the heated object can be displayed, so as to adjust the working state of the gas baking device.

[0041] In one of the embodiments, it also includes a fire transfer channel, which is arranged between two adjacent burners and is respectively connected to the two adjacent burners.

[0042] Beneficial effect: by setting a fire transfer channel between two adjacent burners and connecting the fire transfer channel with 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 second electromagnetic switch valve core to introduce gas into the non-working burner, and then the non-working burner is ignited through the fire transfer channel to put it into a combustion state, thereby quickly increasing the temperature inside the gas baking equipment.

[0043] In one embodiment, it further comprises a light-emitting knob, respectively connected to the first valve stem and the second valve stem, wherein the light-emitting knob is provided with a light-emitting body 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 and off of the luminous body on the luminous knob.

[0045] Beneficial effects: By fixing the luminous knob to the first valve stem and the second valve stem, the first valve stem and the second valve stem can be rotated by rotating the luminous knob, thereby rotating the first plug valve core and the second plug valve core to adjust the amount of gas entering the temperature control valve. A luminous body is also provided on the luminous knob, and the luminous body can change its color or state according to the working state of the temperature control valve. The luminous knob is electrically connected to the luminous knob light switch, and the luminous body on the luminous knob is controlled by the luminous knob light switch; the luminous knob light switch is also electrically connected to an external power supply and a control panel, and the luminous body on the luminous knob is provided with electric energy by an external power supply, and the control panel can control the luminous body by the instructions issued by the luminous knob light switch. By providing a luminous body of at least one color on the luminous knob, the working state of the luminous knob can be judged by the luminous body, so that the user can judge the working state of the temperature control valve, and it is more beautiful.

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

[0047] Beneficial effect: A battery pack is formed by connecting multiple batteries in series or in parallel, and a 3V voltage is provided to the control panel according to the battery pack, thereby avoiding excessive voltage and preventing voltage leakage.

[0048] On the other hand, the present invention further provides a control method for a gas baking device, which is applied to the gas baking device as described above, and the method comprises:

[0049] Obtaining a preset temperature of the gas baking device;

[0050] When the gas baking device is in the temperature control mode, in response to the current temperature in the gas baking device satisfying the preset temperature, the electromagnetic switch valve core is controlled to close the through hole so that the burner burns in a low-fire state. The temperature control mode is characterized by the current temperature in the gas baking device satisfying 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 effect: by obtaining the preset temperature of the gas baking equipment, and when the gas baking equipment is in the temperature control mode, comparing the current temperature in the gas baking equipment with the preset temperature; when the current temperature in the gas baking equipment meets the preset temperature, that is, the current temperature in the gas baking equipment is greater than or equal to the preset temperature, the solenoid switch valve core is controlled to work, so that the solenoid switch valve core closes the through hole, reduces the amount of gas supplied to the burner, and makes the burner burn in a low fire state, thereby controlling the current temperature in the gas baking equipment to be relatively constant, and the current temperature in the gas baking equipment can be accurately controlled.

[0052] In one embodiment, in response to the current temperature in the gas baking device meeting the preset temperature, controlling the electromagnetic switch valve core to close the through hole comprises:

[0053] When the predetermined temperature is greater than a first preset temperature and less than or equal to a 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 in the gas baking device meeting the preset temperature, the first electromagnetic switch valve core is controlled to close the first through hole.

[0055] Beneficial effect: When the preset temperature is greater than the first preset temperature and less than or equal to the second preset temperature, the preset temperature is relatively low. When the current temperature in the gas baking device needs to be heated to meet the preset temperature, the first temperature control valve can be controlled to open the first through hole and the second through hole, thereby increasing the amount of gas transmitted to the burner, controlling the burner to burn in a high-fire state, and quickly increasing the temperature in the gas baking device. When it is detected that the current temperature in the gas baking device meets the preset temperature, the first electromagnetic switch valve core of the first temperature control valve is controlled to close the first through hole, leaving only the second through hole to transmit gas to the burner, so as to control the temperature in the gas baking device to be relatively constant.

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

[0057] When the predetermined 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 current temperature in the gas baking device failing to meet the preset temperature, controlling the second temperature control valve to open the third through hole;

[0059] In response to the current temperature in the gas baking device 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 effect: When the preset temperature is greater than the second preset temperature and less than or equal to the third preset temperature, the preset temperature is relatively high. When the current temperature in the gas baking device needs to be heated to meet the preset temperature, the first temperature control valve can be controlled to open the first through hole and the second through hole, thereby increasing the amount of gas transmitted to the burner, controlling the burner to burn in a high-fire combustion state, and quickly increasing the temperature in the gas baking device. When the preset temperature cannot be met by the burner connected to the first temperature control valve alone, the second temperature control valve is controlled to open the third through hole, so that the burner connected to the second temperature control valve works, and the temperature in the gas baking device is quickly increased by multiple burners working simultaneously. When it is detected that the current temperature in the gas baking device meets the preset temperature, the first electromagnetic switch valve core of the first temperature control valve is controlled to close the first through hole and the second electromagnetic switch valve core of the second temperature control valve is controlled to close the third through hole, leaving only the second through hole in the first temperature control valve to transmit gas to the burner, so as to control the temperature in the gas baking device to be relatively constant.

[0061] In one embodiment, in response to the current temperature in the gas baking device meeting the preset temperature, after the electromagnetic switch valve core is controlled to close the through hole, the method further includes:

[0062] Detecting the current temperature in the gas baking device;

[0063] In response to the current temperature in the gas baking device being lower than the preset temperature, the electromagnetic switch valve core is controlled to open the through hole, so that the burner burns in a high-fire state.

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

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

[0066] In response to turning on the gas baking device, controlling the gas baking device to enter a grilling mode;

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

[0068] The constant temperature control instruction is transmitted to the gas baking device, and the gas baking device is controlled to enter a temperature control mode.

[0069] Beneficial effects: 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 instruction can be generated according to the second button on the control panel; then the constant temperature control instruction is transmitted to the controller of the gas baking equipment, and the gas baking equipment is controlled by the controller 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 comprises:

[0071] When the gas baking device is in the grilling mode, the first through hole and the second through hole of the first temperature control valve are controlled to be opened, and the third through hole of the second temperature control valve is controlled to be opened, and the combustion state of the burner is controlled based on the plug valve core part, and the plug valve core part includes a first plug valve core part and a second plug valve core part.

[0072] Beneficial effect: When the gas baking equipment is in the grilling mode, the electromagnetic switch valve core does not work, and the first through hole and the second through hole of the first temperature control valve are both in the open state, and the third through hole of the second temperature control valve is in the open state. At this time, if the combustion state of the burner needs to be adjusted, it can be adjusted according to the first plug valve core; when the first plug valve core rotates 90° counterclockwise, the first air inlet hole corresponds to the first air inlet channel, and the first valve body is in a large flow state; when the first plug valve core rotates 180° counterclockwise, the second air inlet hole corresponds to the first air inlet channel, and the first valve body is in a small flow state. Similarly, when the second plug valve core rotates 90° counterclockwise, the third air inlet hole corresponds to the second air inlet channel, and the second valve body is in a large flow state; when the second plug valve core rotates 180° counterclockwise, the fourth air inlet hole corresponds to the second air inlet channel, and the second valve body is in a small flow state. The combustion state of the burner is controlled according to the rotation angle of the plug valve core in the plug valve core part, so that the normal use of the gas baking equipment can be ensured when the electromagnetic switch valve core part fails.

[0073] In one embodiment, it also includes:

[0074] Acquire the current temperature in the gas baking device in real time, and analyze the current temperature change trend in the gas baking device;

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

[0076] Beneficial effects: The current temperature in the gas baking equipment is obtained in real time through the temperature sensor, and the current temperature change trend in the gas baking equipment is analyzed according to the obtained temperature; further, according to the current temperature change trend in the gas baking equipment, the temperature change in the gas baking equipment in the future is predicted. If the temperature in the gas baking equipment is lower than the preset temperature in the future, the electromagnetic switch valve core is controlled to work to open the through hole, change the combustion state of the burner, so as to improve the combustion efficiency of the burner and heat the current temperature in the gas baking equipment. If the temperature in 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, change the combustion state of the burner, so as to reduce the combustion efficiency of the burner and avoid providing too much heat to the gas baking equipment. By predicting the future temperature change and realizing the real-time control of the electromagnetic switch valve core, the temperature in the gas baking equipment can be quickly and stably maintained near the preset temperature, the accuracy of temperature control and the stability of the gas baking equipment are improved, and the demand for precise temperature control in the gas baking equipment is met.

DETAILED DESCRIPTION

[0097] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0098] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0099] According to an embodiment of the present invention, Figures 1 to 3As shown, on the one hand, a temperature control valve body assembly is provided, which is applied to gas baking equipment, including: a plurality of first temperature control valves 10, the 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 which are connected in sequence, and the first valve body 11 is also provided with a first through hole 17 and the second through hole 18, the diameter of the first through hole 17 is larger than the diameter of the second through hole 18, the first air outlet channel 14 is connected with the first electromagnetic switch valve core chamber 131 through the first through hole 17 and the second through hole 18 respectively; the first plug valve core portion 12 is arranged in the first plug valve core chamber 121, and is used for conducting or blocking the first air inlet channel 16 and the first plug valve core chamber 121, and the first electromagnetic switch valve core 132 is arranged in the first electromagnetic switch valve core chamber 131 for opening or closing the first through hole 17.

[0100] In this embodiment, the first temperature control valve 10 includes a first valve body 11, which can provide a platform for installation and support of other components, and can make the gas flow in the first valve body 11 according to a predetermined path. For example, the first air inlet channel 16, the first plug valve core chamber 121, the first electromagnetic switch valve core chamber 131 and the first air outlet channel 14 are sequentially connected on the first valve body 11; after the gas enters the first plug valve core chamber 121 through the first air inlet, it can be sequentially transmitted to the first electromagnetic switch valve core chamber 131, the first air outlet channel 14, and finally transmitted to the gas end. A first plug valve core 12 is provided on the first valve body 11, and the first plug valve core 12 is provided in the first plug valve core chamber 121, and the first air inlet channel 16 and the first plug valve core chamber 121 can be manually connected or blocked. By using the first plug 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 part 13 , and the first electromagnetic switch valve core part 13 has a first electromagnetic switch valve core 132 therein. The first electromagnetic switch valve core 132 is arranged in the first electromagnetic switch valve core cavity 131 for opening or closing the first through hole 17 .

[0101] Furthermore, the first valve body 11 is 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 chamber 131 through the first through hole 17 and the second through hole 18 respectively. When the gas baking device is in the grilling mode and requires a large amount of gas, the first electromagnetic switch valve core 132 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 demand of the gas baking device. When the gas baking device is in the temperature control mode, it is necessary to perform more precise control on the gas. At this time, the first through hole 17 is closed by the first electromagnetic switch valve core 132, and the gas is transmitted to the first gas outlet channel 14 through the second through hole 18 with a smaller diameter, and the gas end is in a low-fire combustion state, thereby ensuring that the temperature in the gas baking device is relatively constant. By limiting the diameter size of the first through hole 17 and the second through hole 18, the combustion state of the gas baking device can be more accurately controlled.

[0102] When the gas baking equipment is working, the first through hole 17 and the second through hole 18 of the first temperature control valve 10 are opened to increase the amount of gas delivered to the gas-using end, thereby increasing the combustion effect of the gas-using end to quickly increase the temperature in the gas baking equipment; when the temperature in the gas baking equipment meets the use 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 part 13, so that gas is transmitted to the gas-using end through the second through hole 18 to reduce the amount of gas at the gas-using end, and the gas-using end burns in a low fire state, thereby keeping the temperature in the gas baking equipment relatively constant, so as to realize 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 plug 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 fires of the gas baking equipment under the temperature control mode. Moreover, compared with the gas baking oven using a proportional valve, the structure is simpler and the cost is lower.

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

[0105] In this embodiment, a first sealing gasket 133 is provided at one end of the first electromagnetic switch valve core 132 close to the first through hole 17, and the diameter of the first sealing gasket 133 is greater 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 the first through hole 17 needs to be closed, the first sealing gasket 133 can be supported by the elastic force of the first elastic member 134, so that the first sealing gasket 133 blocks the first through hole 17, and there is no need to continuously supply power to the first electromagnetic switch valve core 13; when the first electromagnetic switch valve core 13 is opened, the first electromagnetic switch valve core 13 works and absorbs the first sealing gasket 133 by the magnet, so as to block the first through hole 17, and there is no need to continuously supply power to the first electromagnetic switch valve core 13, which can effectively save energy consumption and extend the service life of the external power supply 103.

[0106] In one embodiment, the first plug valve core 12 also 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, and the first plug valve core 123 is arranged in the first plug valve core cavity 121; the first plug valve core 123 is provided with a first air inlet hole and a second air inlet hole 125, and the aperture of the first air inlet hole is larger than the aperture of the second air inlet hole 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; the first valve stem 124 is driven to drive the first plug valve core 123 to rotate, thereby controlling the on-off of the gas and the amount of gas. A first air inlet hole and a second air inlet hole 125 are provided on the first plug valve core 123, wherein the aperture of the first air inlet hole is larger than the aperture of the second air inlet hole 125; when the first air inlet hole is opposite to the first air inlet channel 16, the first plug valve core cavity 121 is connected to the first air inlet channel 16, and the amount of gas flowing into the first plug valve core cavity 121 is relatively large, the first temperature control valve 10 is in a large flow state, and the gas end is in a high-fire burning state; when the second air inlet hole 125 is opposite to the first air inlet channel 16, the first plug valve core cavity 121 is connected to the first air inlet channel 16, and the amount of gas flowing into the first plug valve core cavity 121 is relatively small, the first temperature control valve 10 is in a small flow state, and the gas end is in a low-fire burning state. If the first air inlet hole and the second air inlet hole 125 are not opposite to the first air inlet channel 16, the first plug valve core 123 blocks the first plug valve core cavity 121 and the first air inlet channel 16. Manually controlling the combustion state of the gas baking device through the first cock valve core 12 can ensure normal use of the gas baking device when 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 end. The gas flows to the first nozzle 15 through the first gas outlet channel 14, and is transmitted to the gas end through the first nozzle 15, ensuring that the gas at the gas end can be supplied normally.

[0109] like Figure 4 As shown, in one of the embodiments, it also includes a plurality of second temperature-controlled valves 20, the second temperature-controlled 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 chamber 221, a second electromagnetic switch valve core chamber 231 and a third air outlet channel 24 which are connected in sequence, and the second valve body 21 is also provided with a third through hole 27, and the third air outlet channel 24 is connected with the second electromagnetic switch valve core chamber 231 through the third through hole 27; the second plug valve core 22 is arranged in the second plug valve core chamber 221, and is used to conduct or block the second air inlet channel 26 and the second plug valve core chamber 221, and the second electromagnetic switch valve core 232 is arranged in the second electromagnetic switch valve core chamber 231, 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, wherein the second electromagnetic switch valve core 23 also includes a second elastic member 234, which is sleeved on the second electromagnetic switch valve core 232; a second sealing gasket 233 is provided on the second electromagnetic switch valve core 232, and the second elastic member 234 is connected to the second sealing gasket 233; the second plug valve core 22 also 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 arranged in the second plug valve core cavity 221; a third air inlet hole and a fourth air inlet hole 225 are provided on the second plug valve core 223, and the aperture of the third air inlet hole is larger than the aperture of the fourth air inlet hole 225; a second air inlet channel 26 is also provided on the second valve body 21, which is respectively connected to the second plug valve core cavity 221 and the air inlet pipe 106. The second nozzle 25 is connected to the third gas outlet channel 24 and the gas end, respectively. The gas flows to the second nozzle 25 through the third gas outlet channel 24, and is transmitted to the gas end through the second nozzle 25, ensuring that the gas at the gas end can be supplied normally.

[0111] The difference between the second temperature control valve 20 and the first temperature control valve 10 is that a third through hole 27 is provided on the second valve body 21, and the third air outlet channel 24 is connected to the second electromagnetic switch valve core chamber 231 through the third through hole 27, so the specific structure of the second temperature control valve 20 is not repeated here.

[0112] By setting a plurality of first temperature control valves 10 and a plurality of second temperature control valves 20, different temperature control requirements or different working scenes can be met, and more accurate and flexible temperature control can be achieved through the coordinated work of the plurality of temperature control valves. Through the cooperation of the first temperature control valve 10 and the second temperature control valve 20, when the gas baking device is working, the amount of gas delivered to the gas user end is increased by opening the first through hole 17 and the second through hole 18 of the first temperature control valve 10 and the third through hole 27 of the second temperature control valve 20, thereby increasing the combustion effect of the gas user end to quickly increase the temperature in the gas baking device; when the temperature in the gas baking device meets the use 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 user end, and the gas user end burns in a low-fire state, thereby keeping the temperature in the gas baking device relatively constant, so as to achieve the temperature control function of the gas baking device.

[0113] Through the combination of multiple first temperature control valves 10 and multiple second temperature control valves 20, the combustion state of the gas end can be manually controlled according to the plug valve core, and the combustion state of the gas end can be automatically controlled according to the electromagnetic switch valve core, so as to control the temperature in the gas baking equipment and meet the requirements of temperature control in different application scenarios. The gas volume at the gas end is adjusted through the first through hole 17, the second through hole 18 and the third through hole 27 to avoid the situation where the temperature in the gas baking equipment is too high due to excessive gas volume at the gas end, or the temperature in the gas baking equipment is too low due to too fast temperature loss, which can effectively improve the temperature control accuracy of the gas baking equipment.

[0114] On the other hand, Figures 5 to 10 As shown, an embodiment of the present invention further provides a gas baking device, including: a device body 100; a control panel 101, installed on the device 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, arranged at the bottom of the device body 100; a temperature control valve body assembly, 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 body assembly; an air intake pipe 106, on which at least one first temperature control valve 10 and at least one second temperature control valve 20 are provided.

[0115] In this embodiment, by installing a control panel 101 on the device body 100, the user can adjust the working state of the gas baking device according to the control panel 101 and can check the working status of the gas baking device. The 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, so that various electronic components, sensors and controllers can work normally, thereby realizing automatic control of the gas baking device.

[0116] The multiple burners 1012 are arranged at the bottom of the device body 100, so that the heat can be evenly transferred upward to heat the baking space inside the gas baking device. By arranging multiple burners 1012, different heat outputs can be provided according to baking requirements. By controlling the opening or closing and the combustion intensity of different burners 1012, the temperature distribution and heating speed in the gas baking device 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 to the burners 1012 one by one, so that each burner 1012 has a corresponding temperature control valve to accurately control its gas supply. The temperature control valve can adjust the flow of gas according to the temperature in the gas baking equipment, thereby controlling the combustion intensity of the burner 1012 and realizing accurate adjustment of the internal temperature of the equipment.

[0118] The control panel 101 is electrically connected to the electromagnetic switch valve core in the temperature control valve body assembly, so that the control panel 101 can indirectly control the gas supply of the burner 1012 by controlling the opening and closing of the electromagnetic switch valve core. When the control panel 101 receives the temperature information fed back by the temperature sensor 104 and determines that the heat needs to be increased or decreased, it will send a corresponding electrical signal to the electromagnetic switch valve core, and the electromagnetic switch 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 device.

[0119] By arranging 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 can be quickly increased according to the cooperation between the first temperature control valve 10 and the second temperature control valve 20, and 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 fire 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 is arranged between two first temperature control valves 10; or, the first temperature control valve 10 is arranged between two second temperature control valves 20. The specific setting can be made according to the actual use requirements.

[0121] like Figure 7 As shown, in one embodiment, a temperature sensor 104 is further included, which is electrically connected to the control panel 101 and is used to detect the temperature in the gas baking device in real time.

[0122] In this embodiment, by setting up a temperature sensor 104 and electrically connecting it to the control panel 101, the temperature inside the gas baking device can be detected in real time, which is convenient for further adjusting the working state of the gas baking device according to the temperature detected by the temperature sensor 104.

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

[0124] In this embodiment, a plurality of buttons are provided on the control panel 101, and different control instructions are generated according to the plurality of buttons, so as to control the working state of the gas baking device. Through the probe hole 1006 on the control panel 101, the probe can detect the temperature of the heated object in the gas baking device through the probe hole 1006, so as to judge the baking state of the object according to the temperature of the heated object. Through the display unit 1005 on the control panel 101, the temperature in the gas baking device can be intuitively determined and the temperature of the heated object can be displayed, so as to adjust the working state of the gas baking device.

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

[0126] In one of the embodiments, a fire transfer channel 105 is further included, which is disposed between two adjacent burners 1012 and is respectively connected to the two adjacent burners 1012 .

[0127] In this embodiment, by setting a fire transfer channel 105 between two adjacent burners 1012, and connecting the fire transfer channel 105 with the burner 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 fire transfer channel 105 to put it into a 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 the temperature control mode to the grilling 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 fire transfer channel 105 to the non-working burner 1012 to ignite the burner 1012 and put it into a combustion state.

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

[0130] In this embodiment, the luminous knob 102 is fixedly connected to the first valve stem 124 and the second valve stem 224, and the first valve stem 124 and the second valve stem 224 can be rotated by rotating the luminous knob 102, thereby rotating the first plug valve core 123 and the second plug valve core 223 to adjust the amount of gas entering the temperature control valve. A light-emitting body is also provided on the luminous knob 102, and the light-emitting body can change its color or state according to the working state of the temperature control valve. The luminous knob 102 is electrically connected to the luminous knob light switch 107, and the light-emitting knob light switch 107 controls the light-emitting body on the luminous knob 102 to turn on and off; the luminous knob light switch 107 is also electrically connected to the external power supply 103 and the control panel 101, and the external power supply 103 provides power to the light-emitting body on the luminous knob 102, and the control panel 101 can control the light-emitting body to turn on and off through the instructions issued by the luminous knob light switch 107. By providing a light emitting body of at least one color on the light emitting knob 102, the working state of the light emitting knob 102 can be judged by the light emitting body, so that the user can judge the working state of the temperature control valve, and it is more aesthetically pleasing. For example, when the light emitting body is white light, it indicates that the temperature control valve is not working; when the light emitting body is red light, it indicates that the temperature control valve is in working state.

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

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

[0133] In one embodiment, it also includes an ignition button 109, an igniter 1091 and an ignition connection line 1092; the ignition button 109 is electrically connected to the igniter 1091, the ignition connection line 1092 is connected to the ignition 1091, the ignition connection line 1092 is connected to the ignition needle 108, and the ignition needle 108 is arranged on one side of the burner 1012. The igniter 1091 is powered by a battery, and when the ignition button 109 is pressed, the igniter 1091 receives a signal to start discharging, and transmits the signal to the ignition needle 108 through the ignition connection line 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 burner 1010 and a pressure relief valve 1011 .

[0135] It can be understood that the gas baking device provided by the present invention can be but is not limited to a gas baking oven.

[0136] On the other hand, Fig.11 As shown, an embodiment of the present invention further provides a control method for a gas baking device, which is applied to the gas baking device and includes the following steps:

[0137] Step S100, obtaining the preset temperature of the gas baking equipment;

[0138] Step S200, when the gas baking device is in the temperature control mode, in response to the current temperature in the gas baking device satisfying the preset temperature, the electromagnetic switch valve core is controlled to close the through hole, so that the burner 1012 burns in a low fire state. The temperature control mode is characterized by the current temperature in the gas baking device satisfying 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 device is obtained, and when the gas baking device is in the temperature control mode, the current temperature in the gas baking device is compared with the preset temperature; when the current temperature in the gas baking device meets the preset temperature, that is, the current temperature in the gas baking device is greater than or equal to the preset temperature, the solenoid switch valve core is controlled to work, so that the solenoid switch valve core closes the through hole, reduces the amount of gas supplied to the burner 1012, and makes the burner 1012 burn in a low fire state, thereby controlling the current temperature in the gas baking device to be relatively constant, and the current temperature in the gas baking device can be accurately controlled.

[0140] like Fig.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, the first temperature control valve 10 is controlled 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 device meeting the preset temperature, controlling 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 and less than or equal to the second preset temperature, the preset temperature is relatively low. When the current temperature in the gas baking device 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 quickly increasing the temperature in the gas baking device. When it is detected that the current temperature in the gas baking device 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 to transmit gas to the burner 1012, so as to control the temperature in the gas baking device to be relatively constant.

[0144] like Fig.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, controlling 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 device failing to meet the preset temperature, controlling 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 device meeting the preset temperature, controlling 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, when the preset temperature is greater than the second preset temperature and less than or equal to the third preset temperature, the preset temperature is relatively high. When the current temperature in the gas baking device 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 quickly increasing the temperature in the gas baking device. When the preset temperature cannot be met by only the burner 1012 connected to the first temperature control valve 10, the second temperature control valve 20 is controlled to open the third through hole 27, so that the burner 1012 connected to the second temperature control valve 20 is operated, and multiple burners 1012 work simultaneously to quickly increase the temperature in the gas baking device. When it is detected that the current temperature in 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 and the second electromagnetic switch valve core 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 retained to transmit gas to the burner 1012, so that the burner 1012 connected to the first temperature control valve 10 burns in a low fire state, so as to control the temperature in the gas baking equipment to be relatively constant.

[0149] like Fig.14 As shown, in one embodiment, step S200 further includes the following steps:

[0150] Step S300, detecting the current temperature in the gas baking equipment;

[0151] Step S400: In response to the current temperature in the gas baking device 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 is controlled to close the through hole, the current temperature in the gas baking equipment is detected in real time, and the current temperature in the gas baking equipment is compared with the preset temperature; when the current temperature in the gas baking equipment is lower than the preset temperature, the electromagnetic switch valve core is controlled again to open the through hole, so that the burner 1012 burns in a high fire state, and the current temperature in the gas baking equipment is controlled to meet the preset temperature, thereby meeting the user's usage needs.

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

[0154] Step S101, in response to turning on the gas baking device, controlling the gas baking device to enter a barbecue mode;

[0155] Step S102, generating a constant temperature control instruction based on the control panel 101;

[0156] Step S103: transmitting the constant temperature control instruction to the gas baking device, and controlling the gas baking device to enter a temperature control mode.

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

[0158] In one of the embodiments, it also includes: when the gas baking device is in the grilling mode, the first through hole 17 and the second through hole 18 of the first temperature control valve 10 are controlled to be opened, and the third through hole 27 of the second temperature control valve 20 is controlled to be opened, and the combustion state of the burner 1012 is controlled based on the plug valve core part, and the plug valve core part includes a first plug valve core part 12 and a second plug valve core part 22.

[0159] In this embodiment, when the gas baking device is in the grilling mode, the electromagnetic switch valve core does not work, and the first through hole 17 and the second through hole 18 of the first temperature control valve 10 are both in the open state, and the third through hole 27 of the second temperature control valve 20 is in the open state. At this time, if it is necessary to adjust the combustion state of the burner 1012, it can be adjusted according to the first plug valve core 12; when the first plug valve core 123 rotates 90° counterclockwise, the first air inlet hole corresponds to the first air inlet channel 16, and the first valve body 11 is in a large flow state; when the first plug valve core 123 rotates 180° counterclockwise, the second air inlet hole 125 corresponds to the first air inlet channel 16, and the first valve body 11 is in a small flow state. Similarly, when the second plug valve core 223 rotates 90° counterclockwise, the third air inlet hole corresponds to the second air inlet channel 26, and the second valve body 21 is in a large flow state; when the second plug valve core 223 rotates 180° counterclockwise, the fourth air inlet hole 225 corresponds to the second air inlet channel 26, and the second valve body 21 is in a small flow state. The combustion state of the burner 1012 is controlled according to the rotation angle of the plug valve core in the plug valve core, so that the normal use of the gas baking equipment can be guaranteed when the electromagnetic switch valve core fails.

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

[0161] In this embodiment, the current temperature in the gas baking device is obtained in real time through the temperature sensor 104, and the current temperature change trend in the gas baking device is analyzed according to the obtained temperature; specifically, the PID algorithm can be used to analyze the current temperature change trend in the gas baking device. Further, according to the current temperature change trend in the gas baking device, the temperature change in the gas baking device in the future is predicted. If the temperature in the gas baking device is lower than the preset temperature in the future, the electromagnetic switch valve core is controlled to work to open the through hole, change the combustion state of the burner 1012, so as to improve the combustion efficiency of the burner 1012 and heat the current temperature in the gas baking device. If the temperature in the gas baking device is much higher than the preset temperature in the future, the electromagnetic switch valve core is controlled to close the through hole, change the combustion state of the burner 1012, so as to reduce the combustion efficiency of the burner 1012 and avoid providing too much heat to the gas baking device. By predicting the future temperature change and realizing the real-time control of the electromagnetic switch valve core, the temperature in the gas baking device can be quickly and stably maintained near the preset temperature, the accuracy of temperature control and the stability of the gas baking device are improved, and the demand for precise temperature control in the gas baking device is met.
