[0076] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their detailed descriptions will be omitted.

[0077] The terms "a", "an" and "the" are used to denote the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.

[0078] An embodiment of the present invention provides an oven stove, as Figures 1-12As shown, the oven stove includes a cooking component 1 and an oven component 2. The cooking component 1 includes a panel 11 and a burner 12. The oven component 2 includes an upper box body 21 and a lower box body 22. The upper box body 21 is sleeved on the outer periphery of the lower box body 22 and can slide away from or close to the lower box body 22. The lower box body 22 is pivotally connected to the area on the outer periphery of the panel 11 close to the burner 12, so that the oven component 2 is configured with a non-working position or a working position. Wherein, a first through hole 2200 corresponding to the burner 12 is opened at the bottom of the lower box body 22. When the oven component 2 is configured in the working position, the lower box body 22 drives the upper box body 21 to turn above the burner 12, and the burner 12 is inserted into the first through hole 2200. In this application, the oven component 2 is installed on the upper part of the cooking component 1, sharing the burner 12, realizing an integrated stove and oven design. In particular, the same set of burner 12 can not only be used as a cooking fire source for cooking, but also as a heat source for the oven for baking, giving full play to the characteristics of combustion, optimizing the usage scenario, improving the utilization rate of the product, and enhancing the cooking performance and practicality of the equipment. In addition, the upper box body 21 and the lower box body 22 of the oven component 2 in this application are slidably connected, and the upper box body 21 moves away from or close to the lower box body 22 to realize the telescopic function of the oven component 2. In this way, when the oven component 2 is in a non-working state, the upper box body 21 and the lower box body 22 can be stored in a Figures 1-2 folded state as shown; when the oven component 2 needs to be used, pull the upper box body 21 away from the lower box body 22 to make the oven component 2 return to the Figures 3-4 normal state as shown, that is, the oven component 2 in this application adopts a telescopic structure design, realizing that the oven can be telescoped up and down, thereby reducing the storage volume. Finally, the rotational connection between the lower box body 22 and the panel 11 can also rotate the stored oven component 2 away from the burner 12, thereby freeing up the space above the burner 12 and restoring the use of the stove. This structure does not require too much countertop space, using the space behind the stove and on the wall, thus greatly saving kitchen space and solving the problem of large floor space occupied by existing integrated cooking centers, improving the operation convenience and experience of users. Figures 1-4 respectively show four states of the oven component 2 switching from the non-working position to the working position: First, the oven component 2 turns to the rear of the cooking component 1 and is in a folded state. At this time, the oven component 2 is in the non-working position, and the user can normally use the cooking function of the burner 12; Second, the oven component 2 turns above the burner 12 and is in a folded state. At this time, the burner 12 is inserted into the interior of the oven component 2 through the first through hole 2200. At this time, the burner 12 is the heat source of the oven component 2; Third, the oven component 2 above the burner 12 returns to the normal state and the door body 23 is in the open position. At this time, the baking net, baking tray and cooked food can be placed on the top of the lower box body 22, and then the door body 23 is closed and switched to the Figure 4The working state shown, at this time the user can start ignition to cook food. From the design of this application, the space in the kitchen can be fully utilized, making the whole device more compact and saving the space in the kitchen. The stove and oven integrated design is adopted, sharing the burner 12, giving full play to the characteristics of combustion, optimizing the usage scenario, improving the utilization rate of the product, and enhancing the cooking performance and practicality of the device.

[0079] In addition, the oven assembly 2 can rotate and be stored behind the stove assembly 1 to form a state diagram as Figure 1 shown. In some embodiments, the oven assembly 2 can rotate and be stored to the left or right of the stove assembly 1. Again, this application does not make any restrictions as long as the kitchen space can be fully utilized. It should be noted that the orientation words "top", "bottom", "upper", "lower", "left", "front" and "rear" in this application are all described based on the oven assembly 2 being in the working position, that is Figures 3-4 the state shown, where

[0080] In a preferred embodiment of the present invention, as Figures 1-9 shown, the upper box body 21 includes a first outer shell 211, a first inner shell 212 and a limiting structure 213. The first inner shell 212 is sleeved inside the first outer shell 211. A first heat insulation cavity 210 for heat insulation is formed between the first inner shell 212 and the first outer shell 211. The limiting structure 213 is connected to the first outer shell 211 and is used to limit the first inner shell 212; the first heat insulation cotton is installed in the first heat insulation cavity 210. In this application, the limiting structure 213 can not only realize the assembly and fixation of the first outer shell 211 and the first inner shell 212, but also make a preset distance formed between the first outer shell 211 and the first inner shell 212, so that a first heat insulation cavity 210 for heat insulation is formed between the first inner shell 212 and the first outer shell 211. After the assembly of the first outer shell 211 and the first inner shell 212, inserting the first heat insulation cotton into the first heat insulation cavity 210 can form the upper box body 21 with a heat preservation effect. The whole structure is simple, the operation is convenient, and the processing and production efficiency of the upper box body 21 is effectively improved.

[0081] In a preferred embodiment of the present invention, as Figures 1-10 shown, both the bottom of the first outer shell 211 and the first inner shell 212 are provided with a first opening. The limiting structure 213 includes a first flanging 2131 formed by bending the bottom of the first outer shell 211 inward and upward. The free end of the first flanging 2131 is bent outward to form a limiting step 2132. The bottom of the first inner shell 212 is inserted and connected to the limiting step 2132. In this application, both the first outer shell 211 and the first inner shell 212 are rectangular parallelepiped structures. Among them, the front end and the bottom of the first outer shell 211 and the first inner shell 212 are open structures to facilitate the cooperation with the lower box body 22 to form an oven structure with a telescopic inner cavity volume. From Figures 6-9It is not difficult to see from the schematic first outer shell 211 that the first flanging 2131 is an L-shaped structure formed by bending the bottom of the first inner shell 212 inward and upward. The first flanging 2131 and the first inner shell 212 together form a groove structure for defining the thickness of the upper box body 21 or the thickness of the first heat insulation cavity 210. Then, a limiting step 2132 is machined on the inner side of the first flanging 2131. The first inner shell 212 can be inserted into the limiting step 2132 to realize the assembly of the first outer shell 211 and the first inner shell 212. The whole structure is simple, the positioning is accurate, the installation is fast, and it can also ensure the heat preservation effect of the whole upper box body 21.

[0082] In a preferred embodiment of the present invention, as Figures 1-10 shown, the lower box body 22 includes a second outer shell 221, a second inner shell 222 and a second heat insulation cotton. A first through hole 2200 is opened at the bottom of the second outer shell 221, and a second flanging 2211 extending inward is provided at the top of the first through hole 2200. The second inner shell 222 is inserted into the second outer shell 221, and its bottom abuts against the second flanging 2211, so that a second heat insulation cavity 220 is formed between the second outer shell 221 and the second inner shell 222. The second heat insulation cotton is installed in the second heat insulation cavity 220. It is not difficult to see from the attached drawings that the overall structures of the upper box body 21 and the lower box body 22 are the same, both are formed by enclosing an inner and outer shell. The difference is that in the lower box body 22, a first through hole 2200 and a second flanging 2211 are provided at the bottom of the second outer shell 221, and the height of the second flanging 2211 is the thickness of the second heat insulation cotton, realizing the function of limiting and supporting. The whole structure is simple, the positioning is accurate, the installation is fast, and it can also ensure the heat preservation effect of the whole upper box body 21.

[0083] In a preferred embodiment of the present invention, as Figures 1-10 shown, the burner 12 includes a burner head 121 and a pot support 122. The second inner shell 222 includes a bottom wall 2221 at its bottom. The bottom wall 2221 is connected to the pot support 122 and is provided with a second through hole 2201 corresponding to the burner head 121. Among them, the inner diameter of the first through hole 2200 is larger than the outer diameter of the pot support 122, and the second through hole 2201 is larger than the outer diameter of the burner head 121. The purpose of this design is that the burner head 121 is inserted into the inside of the lower box body 22 through the first through hole 2200 and the second through hole 2201, and the bottom wall of the second inner shell 222 firmly falls on the pot support 122, ensuring the combustion efficiency and improving the stability of the oven assembly 2.

[0084] In a preferred embodiment of the present invention, as Figures 1-10The shown pot support 122 includes a support body 1221 and feet 1222. One side of the bottom wall 2221 close to the second through hole 2201 is recessed inward to form a limit groove 2222 corresponding to the support body 1221. An opening groove 2223 corresponding to the feet 1222 is formed on the inner groove wall of the limit groove 2222. The support body 1221 is inserted into the limit groove 2222, and the feet 1222 are inserted through and pass through the opening groove 2223. As the lower box body 22 is flipped from the non-working position to the working position, the bottom wall 2221 stably lands on the pot support 122. The structure where the limit groove 2222 and the feet 1222 are inserted through and pass through the opening groove 2223 can not only improve the connection stability between the second shell 222 and the pot support 122, but also avoid safety problems such as side turning and displacement that may occur to the oven assembly 2 under external force collision during the cooking process, thereby improving the safety performance of the product. In addition, since the feet 1222 pass through the opening groove 2223 and enter the interior of the lower box body 22, some cooking utensils can also be supported, expanding the usage range of the product.

[0085] In a preferred embodiment of the present invention, as Figures 1-10 shown, a second opening is provided at the top of the second outer shell 221 and the second inner shell 222. The top of the second inner shell 222 is first bent outward and then downward to form a mounting groove 2220 with a downward opening. The top of the second outer shell 221 is inserted into the mounting groove 2220. Figure 3 、 7 -10 It is not difficult to see that the outward and downward bending of the top of the second inner shell 222 is used, on the one hand, to cooperate with the second outer shell 221 to form the shell structure of the lower box body 22, and on the other hand, the bent part, that is, the bottom of the mounting groove 2220, can be used as a support for mounting a baking tray or a baking net. When the oven assembly 2 moves to the working position as shown in 3-4, the baking tray and the baking net can be directly placed on the bent part, that is, the top of the lower box body 22, without processing convex bumps for mounting the baking tray and the baking net on the inner wall of the lower box body 22, that is, the second outer shell 222. The entire inner wall is a smooth planar structure, which is convenient for cleaning and does not have the problem of porcelain explosion that easily occurs at the convex bumps of some products.

[0086] In a preferred embodiment of the present invention, as Figures 1-10The outer groove wall of the installation groove 2220 is provided with a limiting hole 22201 for limiting the upper box body 21, and the side wall of the first inner shell 212 is provided with a limiting protrusion 2121 corresponding to the limiting hole 22201. When the oven assembly 2 is used, the upper box body 21 is pulled upward. When the upper box body 21 moves upward to the designed maximum position, the limiting protrusion 2121 is inserted into the limiting hole 22201 to stably limit the upper box body 21 at the set working position, ensuring the smooth operation of the entire oven assembly 2. When the oven assembly 2 is not in use, the upper box body 21 is pushed downward. As the inner wall of the upper box body 21, that is, the first inner shell 212, abuts against the outer side of the bottom of the installation groove 2220, the storage of the oven assembly 2 is completed. By the up-and-down telescoping of the oven assembly, the storage volume is reduced. Coupled with the flipping of the oven assembly 2, more space is further vacated to restore the use of the cooking appliance. This structure does not require too much countertop space and uses the space between the rear of the cooking appliance and the wall, thus greatly saving the kitchen space and solving the problem of large floor space occupied by the existing integrated cooking center, improving the operation convenience and experience of users.

[0087] In a preferred embodiment of the present invention, as Figures 1-10 shown, the front ends of the first outer shell 211, the first inner shell 212, the second outer shell 221 and the second inner shell 222 are all open structures. The upper box body 21 further includes an upper front plate 214 connected between the first outer shell 211 and the first inner shell 212, and the lower box body 22 further includes a lower front plate 223 connected between the second outer shell 221 and the second inner shell 222. After the first heat insulation cotton is inserted into the first heat insulation cavity 210, the upper front plate 214 is connected to the first outer shell 211 and the first inner shell 212 to seal the first heat insulation cavity 210; similarly, after the second heat insulation cotton is inserted into the first heat insulation cavity 220, the lower front plate 223 is connected to the second outer shell 221 and the second inner shell 222 to seal the second heat insulation cavity 220, that is, the upper front plate 214 and the lower front plate 223 can improve the sealing performance and aesthetics of the oven assembly 2.

[0088] In a preferred embodiment of the present invention, as Figures 1-10 shown, the oven assembly 2 further includes a door body 23 and an exhaust pipe 24. The door body 23 is hinged to the top of the first outer shell 211; the exhaust pipe 24 is connected between the first inner shell 212 and the first outer shell 211 to discharge the smoke inside the upper box body 21 to the external space. As Figures 1-5The shown door body 23 is hinged at the top of the first outer shell 211. The door body 23 can be flipped 270°. When the oven is used, the door body 23 is folded down 270° so that it can just cover the cavity. When the oven assembly 2 is stored, the door body 23 can be folded to the top of the first outer shell 211 for storage. In addition, smoke exhaust ports corresponding to the smoke exhaust pipe 24 are provided at the tops of the first outer shell 211 and the first outer shell 212, preferably 2 to 6 smoke exhaust ports. The smoke exhaust ports are flanged outward, and the smoke exhaust pipe 24 is welded to the smoke exhaust ports of the first outer shell 211 and the first outer shell 212 to realize the function of exhausting the smoke in the cavity to the outside.

[0089] In a preferred embodiment of the present invention, as Figure 1 , 6 , 8 shows that the oven stove further includes a mounting seat 3 for mounting the oven assembly 2. The mounting seat 3 includes a support block 31 and a hinge 32. The hinge 32 includes a first hinge leaf 321 and a second hinge leaf 322 hinged to the first hinge leaf 321. The bottom of the support block 31 is fixedly connected to the panel 11. The first hinge leaf 321 is connected to the top of the support block 31. The second hinge leaf 322 is connected to the bottom of the lower box body 22. As the box body assembly 2 is flipped, the side wall of the lower box body 22 abuts against the first hinge leaf 321, and the oven assembly 2 is configured in a non-working position. From Figures 1-4 It is not difficult to see that when the oven assembly 2 is used, the first hinge leaf 321 and the second hinge leaf 322 are parallel, so that the oven assembly 2 can be horizontally placed on the pot support 122; when the oven assembly 2 is not used, the second hinge leaf 322 is flipped 90° relative to the first hinge leaf 321, so that the oven assembly 2 is vertically placed in the rear space of the stove top. At the same time, the gas stove on the stove top can still be used. The present application cleverly utilizes the hinge of the first hinge leaf 321 and the second hinge leaf 322, so that the oven assembly 2 rotates from the non-working position as shown in 1 to the working position above the burner 12. The whole process is simple to operate, the space can be switched freely, and the space utilization efficiency and cooking efficiency are improved.

[0090] In a preferred embodiment of the present invention, as Figure 2 , 8, the oven stove shown in Fig. 11 further includes a temperature sensor 4, a flameout protection device and a controller 5. Among them, the temperature sensor 4 includes a probe 41, a lead wire 42 and a plug connected in sequence. The probe 41 is connected to the lower box body 22 for detecting the temperature inside the oven assembly 2; the flameout protection device is connected to the burner 12 for detecting the combustion condition of the flame; the controller 5 is connected to the stove assembly 1, the oven assembly 2, the temperature sensor 4 and the flameout protection device. Specifically, the panel 11 is provided with a socket 111 for connecting the controller 5 and the temperature sensor 4, and the plug can be inserted into the socket 111 to realize the connection between the controller 5 and the temperature sensor 4. Specifically, it is divided into two cases. Since the integrated stove and oven design is adopted in this application, users can choose the stove function or the oven function according to their needs. When using the stove function, the flameout protection device can detect whether there is fire when the burner 12 is ignited and send a signal to the controller 5. If not, the controller 5 shuts down the entire oven stove, and at this time, a sound or a light display can be emitted to remind the user to check for faults. If there is fire, the burner 12 works and the user can continue cooking. When choosing the oven function, first, the oven assembly 2 in the non-working position shown in Figure 1 needs to be rotated above the pot support 122 shown in Figure 2 , and then the upper box body 21 is pulled upward to the maximum movement position. At this time, the oven assembly 2 is in the state shown in Figure 3 . Then, the baking tray or the baking net is placed on the top of the lower box body 22, and then the door body 23 is rotated so that it can cover the front end of the oven assembly 2 to form a relatively closed cooking cavity. Then the burner 12 is ignited, and the flameout protection device continuously detects the state of the flame during the ignition and operation of the burner 12. If the flame goes out, the controller 5 shuts down the oven stove and emits a sound or a light reminder and gives an error code for the user to troubleshoot. At the same time, the temperature sensor 4 is used to continuously detect the cooking temperature inside the oven assembly 2 and send a signal to the controller 5. The controller 5 can adjust the firepower of the burner 12, thereby accurately controlling the temperature inside the oven assembly 2, dynamically adjusting the heat load, improving the intelligent level and cooking effect of the product, and enhancing the user experience.

[0091] In addition, the temperature sensor 4 in this application can be an NTC sensor assembly, and a detachable connection structure is adopted, and the temperature sensor 4 needs to be connected in place. Since the oven assembly 2 of this application needs to be frequently flipped, if the temperature sensor 4 adopts a conventional connection method, the lead wire 42 needs to be frequently stretched and flipped, which is prone to damage. Therefore, this application designs this structure as a detachable structure, that is, a corresponding interface 111 is designed on the panel 11. The probe 41 is connected to the lead wire 42 and the plug, and the connection of the temperature sensor 4 is completed as the plug is inserted into the socket 111. When the oven assembly 2 is in use, the plug and the interface 111 are connected; when the oven assembly 2 is not in use, the connection between the plug and the interface 111 is disconnected.

[0092] In a preferred embodiment of the present invention, as Figures 12-15 shown, there are multiple burners 12, and the stove component 1 further includes a gas valve assembly 13 for regulating gas. The gas valve assembly 13 includes a main control valve 131, an air outlet pipe assembly 132, and an electromagnetic valve group 133. The air outlet pipe assembly 132 includes an air outlet pipe 1321 for delivering gas to each burner 12; the electromagnetic valve group 133 includes an electromagnetic valve 1331 corresponding to each air outlet pipe 1321. The main control valve 131 and the electromagnetic valve group 133 are respectively connected to the controller 5. The air inlet end of the main control valve 131 is connected to the air outlet end of the gas supply pipe for controlling the on-off of the gas path; the air inlet end of the air outlet pipe assembly 132 is connected to the air outlet end of the main control valve 131, the air inlet end of the electromagnetic valve 1331 is connected to the air outlet end of the air outlet pipe 1321, and the air outlet end of the electromagnetic valve 1331 is connected to the air inlet end of the burner 12 through a gas pipe. The electromagnetic valve 1331 can regulate the gas volume delivered to the corresponding burner 12. As Figures 12-15 shown, the main control valve 131 includes a main control valve body 1311, a main control valve rod 1312, and a main control valve core 1313. The electromagnetic valve 1331 mainly includes an electromagnetic valve body 13311 and an electromagnetic valve core 13312 for controlling the gas flow rate. Among them, the air inlet end of the main control valve body 1311 is connected to the gas supply pipe through an inlet pipe 130, the air outlet end of the main control valve body 1311 is connected to the air outlet pipe assembly 132, and the air outlet end of each air outlet pipe 1321 is connected to the air inlet end of the corresponding electromagnetic valve body 13311. The controller 5 can cut off and connect the gas flow between the entire gas valve assembly 13 and the gas supply pipe by driving the main control valve rod 1312 and the main control valve core 1313; by driving the electromagnetic valve core 13312, it can open or close the gas volume delivered from each air outlet pipe 1321 to the corresponding burner 12, thereby realizing precise control of the firepower. The stove component 1 and the oven component 2 of the present application share the same set of burners 12 and the controller 5, realizing an oven stove integrating the functions of an integrated gas stove and an oven, effectively reducing the number, size, and cost of hardware, and improving the operation convenience:

[0093] The embodiment of the present invention provides a control method for an oven stove, as Figures 16-17 shown, the control method includes:

[0094] Step S100: Power on, obtain the function mode selected by the user. The function mode includes the stove function and the oven function; the user can operate the oven stove to connect the power supply and enter the standby state through the power button on the panel 11, the remote control, or the intelligent APP terminal, etc. At this time, the user can select the required function from the operation area of the panel 11, and the controller 5 obtains and saves the function mode selected by the user, such as the stove function, the oven function, lighting, etc.

[0095] Step S200: Select the cooking appliance function, then start ignition, and the solenoid valve 1331 adjusts the firepower according to the gear selected by the user; if the cooking appliance function is selected, the user needs to operate on the panel 11 and select the corresponding firepower gear. After the controller 5 receives the corresponding user settings, it can control the main control valve 131 to open the gas and ignite. Since the cooking process of the cooking appliance is relatively complex and the firepower required for different foods or different cooking time periods is not the same, the user needs to manually select the current required firepower gear. The controller 5 can adjust the solenoid valve 1331 to the corresponding opening degree according to the firepower gear selected by the user, improving the automation and intelligence level of the cooking appliance.

[0096] Step S300: Select the oven function, then first rotate the oven assembly 2 to the working position, and then detect whether the temperature sensor 4 is operating normally; when the oven function is selected, first, the oven assembly 2 in the non-working position as shown in Figure 1 needs to be rotated to above the pot support 122 as shown in Figure 2 , and then pull the upper box body 21 upward to the maximum movement position. At this time, the oven assembly 2 is in the state as shown in Figure 3 . Then place the baking tray or baking net on the top of the lower box body 22, and then rotate the door body 23 so that it can cover the front end of the oven assembly 2 to form a relatively airtight cooking cavity. Then connect the temperature sensor 4 in place to ensure its normal operation, so that the temperature sensor 4 can detect the temperature inside the oven assembly 2 in real time. The controller 5 adjusts the opening degree of the solenoid valve 1331 in time according to the signal of the temperature sensor 4, dynamically adjusts the heat load, and realizes precise temperature control.

[0097] Step S400: If the temperature sensor 4 is operating abnormally, the oven stove enters the standby state; if the temperature sensor 4 is operating normally, start ignition, and the temperature sensor 4 detects the temperature inside the oven assembly 2 in real time and transmits the signal to the controller 5; if the temperature sensor 4 is operating abnormally, generally the interface 111 and the connector are not connected properly. At this time, the oven stove will be turned off and an alarm signal will be issued, which can be specific sound and light reminders, not limited here. Wait until the temperature sensor 4 works normally and then carry out the cooking work to ensure efficient cooking performance.

[0098] Step S500: The controller 5 controls the opening degree of the solenoid valve 1331 according to the preset temperature and the detected temperature to achieve automatic adjustment of the firepower. The structure of the gas valve assembly 13, the cooperation of the temperature sensor 4 and the controller 5 in this application enable the controller 5 to monitor the temperature inside the oven assembly 2 in real time, dynamically adjust the heat load of the oven assembly 2, and achieve precise temperature control. Specifically, when the oven function is required, the gas valve assembly 13 enters the temperature automatic mode. At this time, the controller 5 only needs to regulate the gas volume output by the solenoid valve 1331 according to the temperature signal. The gas heat load can change with the temperature, ensuring that the preset cooking temperature can be reached inside the oven assembly 2, precisely controlling the temperature, and improving the utilization efficiency and cooking effect.

[0099] In a preferred embodiment of the present invention, as Figure 17 shown in step S500, the steps for the controller 5 to control the opening degree of the solenoid valve 1331 according to the preset temperature and the detected temperature include:

[0100] Step S5001, compare the obtained preset temperature and the detected temperature; assume that the preset temperature set by the user is T, and the real-time detected temperature of the temperature sensor 4 is T1. When the oven function is required, after the user selects the oven function in the control area of the panel 11 and sets the preset temperature to T, the controller 5 saves the preset temperature as T and compares the received detected temperature T1, and then judges whether it is necessary to increase or decrease the firepower of the burner 12.

[0101] Step S5002, when the detected temperature is lower than the preset temperature, increase the firepower by one gear; that is, when the decrease of the detected temperature T1 compared to the preset temperature T is greater than 15%, it means that the real-time temperature inside the oven assembly 2 is too low to meet the baking requirements. At this time, it is necessary to increase the firepower by one gear until the decrease of the detected temperature T1 compared to the preset temperature T is greater than 0 and less than or equal to 15%.

[0102] Step S1003, when the detected temperature is greater than or equal to 85% of the preset temperature and less than the preset temperature, keep the current firepower unchanged; that is, when the decrease of the detected temperature T1 compared to the preset temperature T is greater than 0 and less than or equal to 15%, it means that the real-time temperature inside the oven assembly 2 meets the baking requirements, and the current firepower can be kept.

[0103] Step S1004, when the detected temperature is greater than or equal to the preset temperature and less than 115% of the preset temperature, lower the current firepower by one gear. When the detected temperature T1 is greater than the preset temperature T and the increase is greater than 0 and less than or equal to 15%, it means that the real-time temperature inside the oven assembly 2 is too high. At this time, it is necessary to lower the current firepower by one gear until it meets the preset temperature range.

[0104] Through the above steps, the controller 5 can monitor the temperature inside the oven component 2 in real time, dynamically adjust the heat load, achieve precise temperature control, and improve the utilization efficiency and cooking effect.

[0105] In a preferred embodiment of the present invention, as Figure 17 shown, the control method further includes using a flameout protection device to detect the flame state in real time. If the flame goes out, the oven stove is turned off.

[0106] Specifically, as Figure 17 shown, the steps of selecting the stove function further include: when starting ignition, using the flameout protection device to detect the flame state in real time. If the flame goes out, the oven stove is turned off. When using the stove function, the flameout protection device can detect whether there is fire in the burner 12 and send a signal to the controller 5. If not, the controller 5 turns off the entire oven stove, and at this time, a sound or light display can be emitted to remind the user to check for faults. If there is fire, the burner 12 works and the user can continue cooking. If the oven function is selected: during the start-up and operation of the oven component 2, the flameout protection device detects the flame state in real time. If the flame goes out, the oven stove is turned off. That is, during the ignition to cooking process of the oven component 2, the flameout protection device detects the flame state during the ignition and operation of the burner 12 in real time. If the flame goes out, the controller 5 turns off the oven stove, emits a sound or light reminder, and gives an error code for the user to troubleshoot.
