Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a heat preservation device and an oven. Background Technology

[0002] In most related solutions, barbecue grills have a heat-insulating net located above the main grill. When the user uses the grill to grill food, the front of the net is used to place smaller items such as meat skewers and vegetable skewers. The net uses the rising heat inside the grill cavity to keep the skewers placed on it warm. However, this type of net relies solely on the heat inside the grill cavity for heat retention, making the heat retention effect uncontrollable and resulting in poor overall performance. Utility Model Content

[0003] The present invention aims to at least solve the technical problem of poor heat preservation effect of the heat preservation net of barbecue oven in the prior art or related art.

[0004] Therefore, the first objective of this invention is to provide a heat preservation device.

[0005] The second objective of this invention is to provide a baking oven.

[0006] To achieve the above objectives, an embodiment of the first aspect of this utility model provides a heat preservation device for an oven. The oven includes an oven body, and the heat preservation device includes: a heat preservation plate assembly installed above the oven body along the height direction of the oven body. The heat preservation plate assembly includes: a heat preservation panel; and a first heating device installed below the heat preservation panel for heating the heat preservation panel.

[0007] The heat preservation device provided by this utility model can be used in ovens and the like. The oven includes a furnace body, which includes a heating chamber. Food to be heated can be placed in or above the heating chamber for heating. The heat preservation device includes an insulation plate assembly. The insulation plate assembly is installed along the height direction above the furnace body, specifically above the heating chamber. The insulation plate assembly specifically includes an insulation panel and a first heating device. The upper surface (front) of the insulation panel is used to place food. The first heating device is installed below the lower surface (back) of the insulation panel. The first heating device can heat the insulation panel, thereby heating the food above the insulation panel. With this structure, when using the oven, the first heating device can be turned on to heat the insulation panel, thus using the insulation plate assembly to keep the food warm. This heat preservation device has its own heating structure and does not rely on the heat of the furnace body, making the heat preservation effect more controllable and thus improving the heat preservation effect. Furthermore, since the insulation panel assembly does not rely on the heat of the oven body, this makes the use of the insulation device more flexible and convenient. For example, the insulation device can still achieve the function of heat preservation when the oven is not heated. On the other hand, it makes the structure and installation height of the insulation panel assembly unrestricted, making the structure and installation height of the insulation panel assembly more flexible.

[0008] In any of the above embodiments, optionally, the heat preservation device further includes: a first control device connected to the first heating device for controlling the heating power of the first heating device; a wire for connecting the first heating device and the first control device; and a first adjustment switch connected to the first control device for adjusting the heating power of the first heating device.

[0009] In this embodiment, the heating power of the first heating device can be controlled by the first control device. This allows the heating power to be adjusted according to the type and quantity of food during food preservation, thereby regulating the preservation temperature and ensuring a better match between the temperature and the type or quantity of food. This results in better food preservation and improved taste after heating. Specifically, the preservation device also includes a first adjustment switch. Operating the first adjustment switch generates an input command. Upon receiving this input command, the first control device adjusts the heating level (or heating power) of the first heating device accordingly. Thus, the user can adjust the food preservation temperature by operating the first adjustment switch. A wire connects the first heating device and the first control device, providing power to the first heating device and facilitating signal transmission between them.

[0010] Optionally, the first adjustment switch can be a rotary switch or a push-button switch.

[0011] In any of the above embodiments, optionally, the insulation panel assembly further includes: a bottom cover, installed on the insulation panel, and forming an installation cavity with the insulation panel; wherein, the first heating device is installed in the installation cavity.

[0012] In this embodiment, the bottom cover can shield the first heating device, thereby preventing it from being exposed and providing waterproof and dustproof protection. Furthermore, when the insulation panel assembly includes electrical components, such as an electric heating device, the bottom cover's sealing also prevents leakage from the insulation panel assembly.

[0013] In any of the above embodiments, optionally, the insulation device further includes: a temperature sensor, installed in the mounting cavity, for detecting the temperature of the insulation panel. The insulation device also includes: a temperature display, connected to the temperature sensor, for displaying the temperature detected by the temperature sensor.

[0014] In this embodiment, a temperature sensor can detect the temperature of the insulation panel, and this temperature can be used to adjust the power of the first heating device. A temperature display can show the temperature detected by the temperature sensor, i.e., the temperature of the insulation panel, allowing the user to easily understand the current insulation temperature in real time. This helps the user determine whether the current insulation temperature matches the type or quantity of food. If they do not match, the heating power of the first heating device can be further adjusted to change the insulation temperature.

[0015] In any of the above embodiments, the temperature sensor may optionally be a thermocouple. The number of temperature sensors may be one or more.

[0016] In any of the above embodiments, optionally, the first heating device includes an electric heating device. The electric heating device is a flexible electric heating device, or the electric heating device is a non-flexible electric heating device, that is, a rigid electric heating device.

[0017] In this embodiment, the first heating device is an electric heating device, such as a heating element. The structure of an electric heating device is relatively simple, which simplifies the structure of the heat preservation device. Of course, the first heating device can also be a gas heating assembly, but the structure of a gas heating assembly is more complex and requires gas piping. The type of the first heating device can be reasonably set according to the heating type of the oven. For example, when the oven is an electric oven, the first heating device can be an electric heating device. When the oven is a gas oven, the first heating device can be either an electric heating device or a gas assembly.

[0018] Furthermore, the electric heating device is a flexible one. This design allows the first heating device to be bent and deformed at will, meaning its shape can be adjusted arbitrarily. This increases the area where the first heating device is installed, making its distribution under the insulation panel more uniform, thus enabling even heating of the insulation panel. In addition, the flexible nature of the first heating device reduces its footprint, thereby reducing the overall size of the insulation panel assembly. Of course, the first heating device can also be a non-flexible structure.

[0019] Optionally, the first heating device may be arranged in a serpentine, N-shaped, or wave-shaped configuration.

[0020] A second aspect of this utility model provides an oven, comprising: an oven body; and at least one heat-insulating device provided in any embodiment of the first aspect. The heat-insulating plate assembly is installed above the oven body along its height.

[0021] Since this oven has the heat preservation device provided in any embodiment of the first aspect, it has all the beneficial effects of the heat preservation device provided in any embodiment of the first aspect, which will not be repeated here.

[0022] In any of the above embodiments, optionally, the heat preservation device further includes a first control device and a wire. The first control device is connected to the first heating device and is used to control the heating power of the first heating device. The wire is used to connect the first heating device and the first control device. The oven further includes: a cabinet, the oven body is mounted on the cabinet, and the first control device is mounted on the cabinet; a enclosure surrounding the oven body, the enclosure including a first side and a second side arranged opposite to each other, and brackets are respectively provided on the first side and the second side. One end of the heat preservation board assembly is mounted on the bracket on the first side, and the other end of the heat preservation board assembly is mounted on the bracket on the second side. A wire hole is provided on the first side or the second side. One end of the wire is connected to the first control device, and the other end of the wire passes through the wire hole and is connected to the first heating device.

[0023] In this embodiment, the heat preservation device also includes a first control device and wiring. The first control device is installed on the cabinet independently of the heat preservation panel assembly. The oven also includes a heating body, surrounded by a barrier. The barrier protects the oven body from wind and dust, preventing dust from falling onto the food inside. The heat preservation panel assembly is directly mounted on the first and second sides of the barrier, which are opposite each other. Additionally, brackets are provided on the barrier to secure the heat preservation panel assembly, providing support and limiting its position. Wiring holes are also provided on the barrier, facilitating wiring of the heat preservation panel assembly and making the wiring neater and more convenient.

[0024] The cabinet serves as the supporting structure for the oven and can also provide storage space. The cabinet can also be equipped with wheels (for example, it can be a cart-like structure) to facilitate the movement of the entire oven.

[0025] In any of the above embodiments, optionally, the insulation board assembly is provided with mounting holes that penetrate the insulation board assembly along the height direction of the furnace body.

[0026] In this embodiment, the insulation board assembly is provided with an installation structure, which is used to cooperate with the bracket to achieve positioning. The installation structure may specifically be a mounting hole, a mounting groove, etc. The bracket may be provided with a corresponding mating structure to ensure that the bracket and the insulation board assembly can be reliably supported and positioned.

[0027] In addition, the insulation board assembly may not require an installation structure. For example, when the bracket can form an installation platform, the two ends of the insulation board assembly can be directly supported and installed on the installation platform formed by the bracket.

[0028] In any of the above embodiments, optionally, the oven body includes a second heating device; the oven also includes a second control device, which is installed on the cabinet and connected to the second heating device for controlling the operation of the second heating device; wherein the first control device and the second control device are the same control device, or the first control device and the second control device are set independently of each other.

[0029] In this embodiment, the furnace body is heated by a second heating device. A second control device can control the operation of the second heating device (e.g., control the heating power). In the design, the operation of the first and second heating devices can be controlled by the same control device; in this case, the first and second control devices are the same device. Of course, the first and second control devices can also be set up separately, in which case each heating device is equipped with an independent control device.

[0030] In any of the above embodiments, optionally, the heat preservation device further includes: a temperature display, mounted on the furnace body or cabinet, for displaying the temperature of the heat preservation panel. The heat preservation device further includes: a first adjustment switch, mounted on the furnace body or cabinet and connected to the first control device, for adjusting the heating power of the first heating device.

[0031] In this embodiment, the temperature display of the insulation device is installed independently of the insulation panel assembly on the furnace body or cabinet. The temperature display can be installed away from the first and second heating devices to avoid damage from heating. At the same time, the temperature display can be installed in a prominent location for easy viewing by the user.

[0032] Optionally, the oven includes at least one of the following: gas oven, charcoal oven, electric oven, and pellet oven. That is, the heating method of the oven is not limited, as long as it can generate heat.

[0033] Optionally, the grill is a barbecue grill, such as an outdoor barbecue grill. Ideally, the grill is an outdoor electric grill.

[0034] Optionally, the oven body includes an oven body and an oven lid, with the oven lid mounted on the oven body for opening and closing the heating chamber of the oven body. The oven lid reduces heat loss and improves the oven's heating effect on food; furthermore, it protects food from contamination by foreign objects.

[0035] Optionally, the oven body also includes a cabinet, on which the oven body is mounted. The cabinet facilitates the movement of the entire oven, making it convenient for outdoor use. Furthermore, the cabinet provides storage space, thus solving the oven's storage problem. Specifically, the cabinet includes a storage unit. Wheels are installed at the bottom of the storage unit, allowing for easy movement of the entire oven.

[0036] In this embodiment, the heat preservation device is mainly used for heat preservation, and the heat preservation temperature is greater than 30℃ and less than or equal to 70℃.

Detailed Implementation

[0047] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0049] The following reference Figures 1 to 6 The present application describes the heat preservation device 100 and oven provided in the embodiments of this application.

[0050] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the first aspect of this utility model provides a heat preservation device 100 for an oven, the oven including an oven body 210. The heat preservation device 100 includes a heat preservation plate assembly 1, which is installed above the oven body 210 along the height direction of the oven body 210. The heat preservation plate assembly 1 includes a heat preservation panel 12 and a first heating device 14. The first heating device 14 is installed below the heat preservation panel 12 and is used to heat the heat preservation panel 12.

[0051] The heat preservation device 100 provided by this utility model can be used in ovens and the like. The oven includes an oven body 210, which includes a heating chamber. Food to be heated can be placed in or above the heating chamber for heating. The heat preservation device 100 includes a heat preservation plate assembly 1. The heat preservation plate assembly 1 is installed above the oven body 210 along the height direction, specifically above the heating chamber. The heat preservation plate assembly 1 specifically includes a heat preservation panel 12 and a first heating device 14. The upper surface (front) of the heat preservation panel 12 is used to place food. The first heating device 14 is installed below the lower surface (back) of the heat preservation panel 12. The first heating device 14 can heat the heat preservation panel 12, thereby heating the food above the heat preservation panel 12. This structure allows the first heating device 14 to be activated when using an oven or similar appliance, heating the insulation panel 12 to keep the food warm using the insulation plate assembly 1. This insulation device 100 has its own heating structure and does not rely on the heat from the oven body 210, making its insulation effect more controllable and thus improving the overall heat retention. Furthermore, because the insulation plate assembly 1 does not depend on the heat from the oven body 210, the use of the insulation device 100 is more flexible and convenient. For example, the insulation device 100 can still maintain warmth even when the oven is not heating. Additionally, the structural design and installation height of the insulation plate assembly 1 are unrestricted, allowing for greater flexibility in both design and installation height.

[0052] In any of the above embodiments, optionally, as Figure 1 and Figure 2 As shown, the heat preservation device 100 further includes: a first control device 2, connected to the first heating device 14, for controlling the heating power of the first heating device 14; a wire 3, for connecting the first heating device 14 and the first control device 2; and a first adjustment switch 5, connected to the first control device 2, for adjusting the heating power of the first heating device 14.

[0053] In this embodiment, the heating power of the first heating device 14 can be controlled by the first control device 2. This allows the heating power of the first heating device 14 to be adjusted according to the type and quantity of food during food preservation, thereby regulating the preservation temperature and making it more suitable for the type or quantity of food. This results in better food preservation and improved taste after heating. Specifically, the preservation device 100 also includes a first adjustment switch 5. Operating the first adjustment switch 5 generates an input command. Upon receiving this input command, the first control device 2 can adjust the heating level (or heating power) of the first heating device 14 based on the input command. Thus, the user can adjust the food preservation temperature by operating the first adjustment switch 5. The wire 3 connects the first heating device 14 and the first control device 2, providing power to the first heating device 14 and enabling signal transmission between them.

[0054] Optionally, the first adjustment switch 5 can be a rotary switch 52 or a push-button switch.

[0055] In any of the above embodiments, optionally, as Figure 1 and Figure 2 As shown, the insulation board assembly 1 also includes: a bottom cover 16, which is installed on the insulation panel 12 and forms an installation cavity with the insulation panel 12; wherein, the first heating device 14 is installed in the installation cavity.

[0056] In this embodiment, the bottom cover 16 can shield the first heating device 14, thereby preventing the first heating device 14 from being exposed and achieving waterproof and dustproof protection for the first heating device 14. In addition, when the insulation board assembly 1 includes electrical components, such as when the first heating device 14 is an electric heating device, the sealing of the bottom cover 16 can also prevent the insulation board assembly 1 from leaking electricity.

[0057] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the insulation device 100 further includes a temperature sensor 18, installed inside the mounting cavity, for detecting the temperature of the insulation panel 12. The insulation device 100 also includes a temperature display 4, connected to the temperature sensor 18, for displaying the temperature detected by the temperature sensor 18.

[0058] In this embodiment, the temperature sensor 18 can detect the temperature of the insulation panel 12, and the power of the first heating device 14 can be adjusted accordingly based on this temperature. The temperature display 4 can display the temperature detected by the temperature sensor 18, i.e., the temperature of the insulation panel 12, so that the user can easily know the current insulation temperature in real time. This allows the user to determine whether the current insulation temperature matches the type or quantity of food. If they do not match, the heating power of the first heating device 14 can be further adjusted to change the insulation temperature.

[0059] In any of the above embodiments, the temperature sensor 18 may optionally be a thermocouple. The number of temperature sensors 18 may be one or more.

[0060] In any of the above embodiments, the first heating device 14 may optionally be an electric heating device.

[0061] In this embodiment, the first heating device 14 is an electric heating device, such as a heating element. The structure of an electric heating device is relatively simple, which simplifies the structure of the heat preservation device 100. Of course, the first heating device 14 can also be a gas heating assembly, but the structure of a gas heating assembly is more complex and requires a gas pipeline. The type of the first heating device 14 can be reasonably set according to the heating type of the oven. For example, when the oven is an electric oven, the first heating device 14 can be an electric heating device. When the oven is a gas oven, the first heating device 14 can be either an electric heating device or a gas assembly.

[0062] In any of the above embodiments, the first heating device 14 may optionally be a flexible electric heating device.

[0063] In this embodiment, the first heating device 14 is a flexible electric heating device, which allows it to be bent and deformed at will. This increases the area where the first heating device 14 is installed, making it more evenly distributed under the insulation panel 12. This ensures that the first heating device 14 can heat the insulation panel 12 uniformly. Furthermore, the flexible electric heating device 14 also reduces its size, thus reducing the overall volume of the insulation panel assembly.

[0064] Optionally, the first heating device 14 is arranged in a serpentine, N-shaped, or wave-shaped configuration.

[0065] like Figures 1 to 6 As shown, an embodiment of the second aspect of this utility model provides an oven, including: an oven body 210; and at least one heat preservation device 100 provided in any embodiment of the first aspect. The heat preservation plate assembly 1 is installed above the oven body 210 along the height direction of the oven body 210.

[0066] Since this oven has the heat preservation device 100 provided in any embodiment of the first aspect, the oven has all the beneficial effects of the heat preservation device 100 provided in any embodiment of the first aspect, which will not be repeated here.

[0067] In any of the above embodiments, optionally, as Figure 3 , Figure 4 and Figure 5As shown, the heat preservation device 100 also includes a first control device 2 and a wire 3. The first control device 2 is connected to the first heating device 14 and is used to control the heating power of the first heating device 14. The wire 3 is used to connect the first heating device 14 and the first control device 2. The oven also includes: a cabinet 230, an oven body 210 mounted on the cabinet 230, and the first control device 2 mounted on the cabinet 230; and a enclosure 250, which surrounds the oven body 210. The enclosure 250 includes a first side and a second side arranged opposite to each other. A bracket 252 is provided on the first side and the second side respectively. One end of the heat preservation board assembly 1 is mounted on the bracket 252 on the first side, and the other end of the heat preservation board assembly 1 is mounted on the bracket 252 on the second side. A wire hole 254 is provided on the first side or the second side. One end of the wire 3 is connected to the first control device 2, and the other end of the wire 3 passes through the wire hole 254 and is connected to the first heating device 14.

[0068] In this embodiment, the heat preservation device 100 also includes a first control device 2 and a wire 3. The first control device 2 is installed on the cabinet 230 independently of the heat preservation panel assembly 1. The oven also includes a heating oven body 210, and a surrounding enclosure 250 is provided around the oven body 210. The enclosure 250 can protect the oven body 210 from wind and dust, preventing dust from falling onto the food inside the oven body 210. The heat preservation panel assembly 1 is directly mounted on the first and second sides of the enclosure 250, which are opposite to each other. At the same time, in order to fix the heat preservation panel assembly 1, a bracket 252 is provided on the enclosure 250, which can support and limit the heat preservation panel assembly 1. The enclosure 250 is also provided with a wire hole 254, which facilitates the wiring of the heat preservation panel assembly 1, making the wiring of the heat preservation panel assembly 1 neater and more convenient.

[0069] like Figure 3 , Figure 4 and Figure 5 As shown, cabinet 230 is the supporting structure for the oven and can have storage space. Cabinet 230 can also be equipped with casters (for example, cabinet 230 can be a cart 232) to facilitate the movement of the entire oven.

[0070] Furthermore, such as Figure 3 , Figure 4 and Figure 5 As shown, the insulation board assembly 1 is provided with an installation structure, which is used to cooperate with the bracket 252 to achieve positioning. The installation structure may specifically be a mounting hole 10, a mounting groove, etc. The bracket 252 may be provided with a corresponding mating structure to ensure that the bracket 252 and the insulation board assembly 1 can be reliably supported and positioned.

[0071] In addition, the insulation board assembly 1 may not have an installation structure. For example, when the bracket 252 can form an installation platform, the insulation board assembly 1 can be directly supported and installed on the installation platform formed by the bracket 252 using both ends.

[0072] In any of the above embodiments, optionally, as Figure 6 As shown, the oven body 210 includes a second heating device 212; the oven also includes a second control device 240, which is installed on the cabinet 230 and connected to the second heating device 212 for controlling the operation of the second heating device 212; wherein, the first control device 2 and the second control device 240 are the same control device, or the first control device 2 and the second control device 240 are set independently of each other.

[0073] In this embodiment, the furnace body 210 is heated by the second heating device 212. The second control device 240 can control the operation of the second heating device 212 (e.g., control the heating power). In the design, the operation of the first heating device 14 and the second heating device 212 can be controlled by the same control device; in this case, the first control device 2 and the second control device 240 are the same control device. Of course, the first control device 2 and the second control device 240 can also be set separately; in this case, the first heating device 14 and the second heating device 212 are each equipped with an independent control device.

[0074] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heat preservation device 100 also includes: a temperature display 4, installed on the furnace body 210 or cabinet 230, for displaying the temperature of the heat preservation panel 12. The heat preservation device 100 also includes: a first adjustment switch 5, installed on the furnace body 210 or cabinet 230, connected to the first control device 2, for adjusting the heating power of the first heating device 14.

[0075] In this embodiment, the temperature display 4 of the insulation device 100 is installed independently of the insulation board assembly 1 on the furnace body 210 or cabinet 230. The temperature display 4 can be installed away from the first heating device 14 and the second heating device 212, thus avoiding damage to the temperature display 4 due to heat. At the same time, the temperature display 4 can be installed in a relatively conspicuous place for easy viewing of the temperature by the user.

[0076] Optionally, the oven includes at least one of the following: gas oven, charcoal oven, electric oven, and pellet oven. That is, the heating method of the oven is not limited, as long as it can generate heat.

[0077] Optionally, the grill is a barbecue grill, such as an outdoor barbecue grill. Ideally, the grill is an outdoor electric grill.

[0078] Optionally, the oven body 210 includes an oven body 210 and an oven cover 220. The oven cover 220 is installed on the oven body 210 and is used to open and close the heating chamber of the oven body 210. The oven cover 220 can reduce heat loss and improve the heating effect of the oven on the food. On the other hand, the oven cover 220 can also protect the food from contamination by foreign objects.

[0079] Optionally, the oven body 210 also includes a cabinet 232, on which the oven body 210 is mounted. The cabinet 232 facilitates the movement of the entire oven, making it convenient for outdoor use. Furthermore, the cabinet 232 provides storage space, thus solving the oven's storage problem. Specifically, the cabinet 232 includes a cabinet body 230 for storage. Wheels are provided at the bottom of the cabinet body 230, facilitating the movement of the entire oven.

[0080] In this embodiment, the heat preservation device 100 is mainly used for heat preservation, and the heat preservation temperature is greater than 30℃ and less than or equal to 70℃.

[0081] The following describes an outdoor barbecue grill in a specific embodiment.

[0082] Most existing barbecue grills have a heat preservation net located above the grill. When users use this grill to grill food, the surface of the heat preservation net is used to place smaller skewers such as meat skewers and vegetable skewers. The heat rising inside the grill cavity keeps the skewers placed on the heat preservation net warm. However, the required heat preservation temperature is different for each type of food. Sometimes, if the heat preservation temperature is too low, it will affect the taste of the food and reduce the user experience.

[0083] In the proposed outdoor gas-fired oven, the insulation netting is mounted on supports on both sides of the oven body, and the heat retention comes from the oven's residual heat. The farther away from the heating element, the lower the temperature. The higher the oven body, the lower the insulation temperature. Different types of food require different insulation temperatures; if the insulation temperature is too low, it affects the taste of the food and reduces the user experience.

[0084] Another type of outdoor gas oven in the relevant solution has multiple layers of grilling mesh on the oven body. Although this increases the heat preservation area, the heat preservation effect is not good.

[0085] Based on the furnace body of the relevant solution, this embodiment adds a temperature-adjustable heat preservation net (heat preservation device 100), which can not only ensure the normal use of the heat preservation net, but also achieve precise temperature adjustment and heat preservation, preventing the heat preservation temperature from being too low and affecting the taste of the food. This brings convenience to users and increases the enjoyment of cooking.

[0086] The external structure of the insulation net in this embodiment is as follows: Figure 2 As shown.

[0087] like Figure 1 As shown, the heat preservation mesh structure of this embodiment includes a heat preservation mesh panel (heat preservation panel 12), an alloy heating wire (first heating device 14), a thermocouple (temperature sensor 18), a heat preservation mesh bottom box (bottom cover 16), a connecting wire (wire 3), a control circuit board (first control device 2), a heat preservation temperature display screen (temperature display 4), and a knob (rotary switch 52).

[0088] Figure 3 and Figure 4 A schematic diagram of the structure of an electric grill using an insulating mesh is shown. In this configuration, the insulating mesh control circuit board is integrated into the grill's controller (second control device 240). The insulating temperature can be set via a knob. The insulating temperature display shows both the real-time insulating temperature and the set insulating temperature.

[0089] like Figure 2 and Figure 5 As shown, the insulation mesh is equipped with clips (mounting holes 10) and is mounted on the supports 252 on both sides of the furnace body 210. Further, as... Figure 5 As shown, the side plate of the furnace body 210 is provided with a wire inlet (wire hole 254), through which the connecting wire of the insulation mesh can enter.

[0090] The insulation net of this embodiment can be used not only in electric ovens, but also in gas ovens, charcoal ovens, pellet ovens, etc. Furthermore, the insulation net in this application can also be used independently (a power supply can be added when using it).

[0091] This embodiment provides a novel electric oven with an adjustable insulation mesh temperature and a simple structure, which solves the problem of the insulation mesh temperature being too low and affecting the taste of the food.
