Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a cooking appliance. Background Technology

[0002] Currently, the cooking cavity of cooking appliances is at a high temperature when they are working, which leads to a high ambient temperature in the housing and power board components.

[0003] In related technologies, heat insulation is usually achieved by increasing the distance between the shell and the cooking cavity, and filling the space between the shell and the cooking cavity with heat insulation material. However, this method results in a larger overall size and heavier product for the cooking appliance. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, the present invention provides a cooking utensil.

[0006] In view of this, the present invention provides a cooking appliance, comprising: a housing; a cooking part disposed within the housing, the cooking part including an opening; and a heat insulation plate assembly located between the housing and the cooking part, the heat insulation plate assembly surrounding the outside of the cooking part and disposed to avoid the opening; wherein a first support structure is provided between the cooking part and the heat insulation plate assembly, the cooking part being supported within the heat insulation plate assembly by the first support structure, so that the heat insulation plate assembly and the cooking part are spaced apart; the heat insulation plate assembly is provided with a second support structure, the heat insulation plate assembly being supported within the housing by the second support structure, so that the housing and the heat insulation plate assembly are spaced apart.

[0007] The cooking appliance provided by this invention includes a shell, a cooking part, and a heat insulation plate assembly. The cooking part is disposed within the shell, and the heat insulation plate assembly surrounds the cooking part on its outer side, avoiding any openings, to insulate the cooking part from heat transfer to the shell. The cooking part is spaced apart from the heat insulation plate assembly by a first support structure, creating a heat insulation gap between them. This gap provides air insulation, effectively preventing heat transfer from the cooking part to the shell and improving the insulation effect. Simultaneously, the heat insulation plate assembly is supported within the shell by a second support structure, creating another heat insulation gap between it and the shell. This gap provides air insulation, effectively reducing heat transfer from the heat insulation plate assembly to the shell. Therefore, it is not necessary to increase the distance between the cooking part and the shell or fill the space between them with insulation material, thus reducing the overall weight and volume of the cooking appliance and facilitating its storage and movement.

[0008] The cooking appliance provided by the present invention may also have the following additional technical features:

[0009] In some embodiments, the first support structure may optionally include a bracket located between the cooking section and the heat insulation assembly, wherein the cooking section is supported within the heat insulation assembly by the bracket, such that the cooking section and the heat insulation assembly are spaced apart.

[0010] In this embodiment, the first support structure includes a bracket located between the cooking section and the heat insulation plate assembly, thus creating a heat insulation gap between them. Since the temperature inside the cooking cavity is high during cooking, this heat insulation gap improves the heat insulation effect. It is understood that the bracket has a smaller support area, reducing the contact area between the heat insulation plate assembly and the cooking section, which helps to reduce heat transfer from the cooking section to the heat insulation plate assembly.

[0011] In some embodiments, optionally, one end of the bracket is supported on the heat insulation plate assembly in the vertical direction, and the other end is connected to the cooking unit.

[0012] In this embodiment, the two ends of the bracket along the vertical direction are respectively supported between the heat insulation plate assembly and the cooking part, which can improve the support effect of the bracket on the cooking part and ensure the stability and reliability of the cooking part.

[0013] In some embodiments, optionally, the cooking section has first flanges on opposite sides along a first direction, and the support is located on both sides of the cooking section along the first direction; wherein, in the vertical direction, one end of the support is supported on the bottom of the first flange, and the other end of the support is connected to the heat insulation plate assembly.

[0014] In this embodiment, the cooking unit has first flanges on both sides along the first direction. One end of the bracket is supported on the bottom of the first flange, and the other end is connected to the heat insulation plate assembly, thus supporting the cooking unit. Simultaneously, the heat insulation plate assembly contacts the first flanges through the bracket, reducing heat transfer from the cooking unit to the heat insulation plate assembly. Furthermore, the first flanges are located on both sides of the cooking unit along the first direction, causing the bracket to be located on both sides of the cooking unit along the first direction, thereby reducing the vertical space occupied by the bracket and lowering the vertical height of the cooking appliance.

[0015] In some embodiments, the cooking section may optionally include: a cooking cavity having an opening on one side along a second direction; a baffle connected to the cooking cavity and surrounding the periphery of the opening, the baffle being connected to the housing; wherein the second support structure includes a second flange and a third flange, the second flange being located on the side of the heat insulation plate assembly near the opening, the third flange being located on the side of the heat insulation plate assembly away from the opening, the second flange being connected to the baffle, and the third flange being connected to the housing.

[0016] In this embodiment, the cooking unit includes a cooking cavity and a baffle. The cooking cavity has an opening, and the baffle surrounds the periphery of the opening and is connected to the housing. The second support structure includes a second flange and a third flange. The heat insulation plate assembly is connected to the baffle via the second flange, and the baffle is connected to the housing, thereby supporting the front end of the heat insulation plate assembly along the second direction against the housing. Simultaneously, the heat insulation plate assembly is connected to the housing via the third flange, thereby supporting the rear end of the heat insulation plate assembly along the second direction within the housing. The second and third flanges facilitate the installation of the heat insulation plate assembly and the housing, improving the connection stability between them. Furthermore, the second and third flanges reduce the indirect contact area between the heat insulation plate assembly and the housing, which helps reduce the heat transferred from the heat insulation plate assembly to the housing, thus reducing the temperature rise of the housing.

[0017] In some embodiments, the housing may optionally include: a cover body covering the outside of the cooking cavity and connected to a baffle; a back plate disposed at one end of the cover body away from the baffle in a second direction, and a heat insulation plate assembly connected to the back plate via a third flange; and a bottom plate disposed at the bottom of the cooking section, with the bottom of the back plate supported on the bottom plate and the bottom of the baffle connected to the bottom plate.

[0018] In this embodiment, the housing includes a cover, a back plate, and a bottom plate. The cover is positioned over the outside of the cooking cavity and connected to a baffle. The back plate is located on the side of the cooking cavity away from the opening along a second direction and is connected to the cover. The bottom plate is located at the bottom of the cooking cavity and is connected to the cover, baffle, and back plate. Thus, the cover, back plate, and bottom plate surround the cooking section. The heat insulation plate assembly is connected to the back plate via a third flange. The bottom of the back plate is supported by the bottom plate, thereby fixing the heat insulation plate assembly at both ends along the second direction and reducing the contact area between other parts of the heat insulation plate assembly and the housing, thereby improving the heat insulation effect.

[0019] In some embodiments, the bottom plate is optionally provided with supporting ribs, and the bottom of the back plate is supported by the supporting ribs. In this embodiment, the bottom plate is provided with supporting ribs, and the bottom of the back plate is supported by the supporting ribs. That is, the heat insulation panel assembly is connected to the back plate through a third flange, and the back plate is supported by the supporting ribs on the bottom plate. This not only fixes the heat insulation panel assembly, but also ensures that there is a small contact area between the heat insulation panel assembly and the back plate, and between the back plate and the bottom plate. This greatly reduces the heat transfer between the heat insulation panel assembly and the shell, and improves the heat insulation effect.

[0020] In some embodiments, the support ribs are optionally arranged in a strip shape and extend along a second direction. In this embodiment, the support ribs are strip structures extending along the second direction, resulting in a smaller contact area between the back plate and the support ribs, which can reduce the amount of heat transfer between the insulation panel assembly and the base plate.

[0021] In some embodiments, the back panel may optionally include: a first back panel disposed on the side of the cooking section away from the opening along a second direction, an insulation plate assembly connected to the first back panel via a third flange, and an end of the first back panel supported by a support rib; and a second back panel disposed on the side of the first back panel away from the opening and spaced apart from the first back panel.

[0022] In this embodiment, the back panel includes a first back panel and a second back panel. Both the first and second back panels are located on the side of the cooking section away from the opening along the second direction, with the second back panel located outside the first back panel. The heat insulation plate assembly is connected to the first back panel via a third flange. The first back panel is supported on the support ribs of the base plate, thereby fixing the heat insulation plate assembly and extending the path of heat transfer from the heat insulation plate assembly to the outside, thus improving the heat insulation effect. The second back panel is spaced apart from the first back panel, which can also block the heat generated by the cooking section. At the same time, electrical components can be installed within this gap, reducing the space occupied by the cooking appliance in the height and left-right directions.

[0023] In some embodiments, the cooking appliance may optionally include an electrical control box disposed between the first back panel and the second back panel.

[0024] In this embodiment, the control box is positioned between the first back panel and the second back panel, which keeps the temperature at the location of the control box low and also avoids occupying other space of the cooking appliance.

[0025] In some embodiments, the cooking appliance may optionally include: a fan disposed between the first back panel and the second back panel, with the cover and the heat insulation plate assembly enclosing a channel, one end of the fan communicating with the channel, and the other end of the fan communicating with the electrical control box; wherein the housing is provided with an air inlet, the channel is provided with an air outlet, the electrical control box is communicated with the air inlet, and when the fan is turned on, the airflow flows from the air inlet through the electrical control box and then out of the channel through the air outlet.

[0026] In this embodiment, the fan is located between the first back plate and the second back plate. When the fan is turned on, the airflow enters the electrical control box through the air inlet on the housing, and flows out of the channel through the air outlet after passing through the electrical control box, thereby achieving heat dissipation for the electrical control box and the cooking part.

[0027] In some embodiments, the base plate is optionally provided with heat dissipation holes, which are located on the side of the electrical control box away from the air inlet.

[0028] In this embodiment, the base plate is provided with heat dissipation holes, which enable natural heat dissipation and improve the cooking effect of the cooking appliance. At the same time, the heat dissipation holes and the air inlet are located on both sides of the control box. The control box can isolate the heat from the heat dissipation holes and prevent the heat from the bottom of the cooking unit from flowing to the control box under the action of the fan, thus ensuring the heat dissipation effect of the electrical components inside the control box.

[0029] In some embodiments, the heat insulation plate assembly may optionally include a plurality of heat insulation plates; at least two heat insulation plates are respectively located on both sides of the cooking section along the vertical direction, at least one heat insulation plate is located on the side of the cooking section away from the opening along the second direction, and at least two heat insulation plates are respectively located on both sides of the cooking section along the first direction; wherein the heat insulation plate located at the top of the cooking section and the heat insulation plate located on the side of the cooking section away from the opening form a third flange, and the heat insulation plate located at the bottom of the cooking section has a second flange on the side of the cooking section near the opening along the second direction.

[0030] In this embodiment, the heat insulation plate assembly includes multiple heat insulation plates, which surround the cooking section on both sides along the vertical direction, both sides along the first direction, and the side of the cooking section away from the opening along the second direction, achieving all-round heat insulation of the cooking section and improving the heat insulation effect. Simultaneously, the heat insulation plate located at the top of the cooking section and the heat insulation plate located on the side of the cooking section away from the opening form a third flange, which connects to the back plate of the housing, reducing the number of parts used and lowering the assembly difficulty; the heat insulation plate located at the bottom of the cooking section has a second flange on the side along the second direction near the opening, securing the front end of the heat insulation plate assembly.

[0031] Optionally, there may be multiple second flanges, which are spaced apart along the first direction.

[0032] Optionally, the number of second flanges is two, and the arrangement of two second flanges reduces the contact area between the heat insulation panel assembly and the baffle.

[0033] In some embodiments, optionally, the cover and the heat insulation panel assembly are spaced apart; and / or the back panel and the heat insulation panel assembly are spaced apart; and / or the bottom plate and the heat insulation panel assembly are spaced apart.

[0034] In this embodiment, a heat insulation gap is provided between the cover and the heat insulation plate assembly, and / or between the back plate and the heat insulation plate assembly, and / or between the bottom plate and the heat insulation plate assembly, which helps to prevent heat from being transferred to the outside.

[0035] In some embodiments, the cooking appliance may optionally include: a heat insulation cotton assembly, which is wrapped around the outer wall of the cooking part and disposed to avoid the opening, and is located between the cooking part and the heat insulation plate assembly and spaced apart from the heat insulation plate assembly.

[0036] In this embodiment, the cooking appliance also includes a heat insulation cotton assembly. The heat insulation cotton assembly is wrapped around the outer wall of the cooking part and is positioned to avoid openings, thereby insulating the cooking part from heat. The heat insulation cotton assembly is lightweight, and when combined with the heat insulation plate assembly, it can improve the heat insulation effect. Furthermore, the heat insulation cotton assembly and the heat insulation plate assembly are spaced apart, which can further improve the heat insulation effect.

[0037] In some embodiments, optionally, the thickness of the portion of the heat insulation cotton assembly away from the opening along the second direction is a first thickness, and the thickness of the portion of the heat insulation cotton assembly corresponding to the periphery of the cooking part is a second thickness, wherein the first thickness is greater than the second thickness.

[0038] In this embodiment, the first thickness is greater than the second thickness, that is, the thickness of the heat insulation cotton assembly along the second direction on the back of the cooking part is larger, which can improve the heat insulation effect on the back of the cooking part, thereby ensuring the working reliability of the control system (e.g., control box) of the cooking appliance.

[0039] In some embodiments, the insulation cotton assembly may optionally include a first insulation cotton surrounding both sides of the cooking section along the vertical direction and the side of the cooking section away from the opening along the second direction; and a second insulation cotton surrounding both sides of the cooking section along the first direction and the side of the cooking section away from the opening along the second direction, wherein the first insulation cotton and the second insulation cotton are stacked on the side of the cooking section away from the opening along the second direction.

[0040] In this embodiment, the heat insulation cotton assembly includes a first heat insulation cotton and a second heat insulation cotton. The first heat insulation cotton surrounds both sides of the cooking part along the vertical direction and the side away from the opening along the second direction. That is, the first heat insulation cotton extends from one side of the cooking part along the vertical direction towards the back of the cooking part along the second direction, and after passing the back of the cooking part, it extends from the other side of the cooking part along the vertical direction towards the opening of the cooking part, thus wrapping the cooking part. The second heat insulation cotton is located on both sides of the cooking part along the first direction and the side away from the opening along the second direction. That is, the second heat insulation cotton extends from one side of the cooking part along the first direction towards the back of the cooking part along the second direction, and after passing the back of the cooking part, it extends from the other side of the cooking part along the first direction towards the opening of the cooking part. This makes the first heat insulation cotton and the second heat insulation cotton arranged in a cross shape, thereby providing at least two layers of heat insulation cotton structure on the back of the cooking part, improving the heat insulation effect of the back of the cooking part.

Detailed Implementation

[0054] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention 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.

[0055] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0056] The following reference Figures 1 to 9 A cooking appliance is described according to some embodiments of the present invention.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, according to an embodiment of the present invention, a cooking appliance is provided, comprising: a housing 1; a cooking part 2 disposed within the housing 1, the cooking part 2 including an opening 20; and a heat insulation plate assembly 3 located between the housing 1 and the cooking part 2, the heat insulation plate assembly 3 surrounding the outside of the cooking part 2 and avoiding the opening 20; wherein a first support structure 4 is provided between the cooking part 2 and the heat insulation plate assembly 3, the cooking part 2 being supported within the heat insulation plate assembly 3 by the first support structure 4, so that the heat insulation plate assembly 3 is spaced apart from the cooking part 2; the heat insulation plate assembly 3 is provided with a second support structure 5, the heat insulation plate assembly 3 being supported within the housing 1 by the second support structure 5, so that the housing 1 and the heat insulation plate assembly 3 are spaced apart.

[0058] The cooking appliance provided by the present invention includes a housing 1, a cooking part 2 and a heat insulation plate assembly 3. The cooking part 2 is disposed inside the housing 1. The heat insulation plate assembly 3 surrounds the cooking part 2 on the outside of the cooking part 2 and avoids the opening 20 between the cooking part 2 and the housing 1 to insulate the cooking part 2 from heat transfer to the housing 1. The cooking section 2 is connected to the heat insulation plate assembly 3 via the first support structure 4, with the cooking section 2 and the heat insulation plate assembly 3 spaced apart, thus forming a heat insulation gap between them. This heat insulation gap creates air insulation, effectively preventing the cooking section 2 from transferring heat to the shell 1, thereby improving the heat insulation effect. At the same time, the heat insulation plate assembly 3 is supported inside the shell 1 via the second support structure 5, with the heat insulation plate assembly 3 and the shell 1 spaced apart, thus forming a heat insulation gap between them. This heat insulation gap creates air insulation, effectively reducing the heat transfer from the heat insulation plate assembly 3 to the shell 1. Therefore, it is not necessary to increase the distance between the cooking section 2 and the shell 1 or fill the space between the cooking section 2 and the shell 1 with heat insulation material, which can reduce the overall weight and volume of the cooking appliance and facilitate its storage and movement.

[0059] Understandably, the cooking section 2 and the heat insulation plate assembly 3 are only in contact through the first support structure 4, greatly reducing the contact area between them and allowing the cooking section 2 to be suspended within the heat insulation plate assembly 3, forming a heat insulation gap. Similarly, the heat insulation plate assembly 3 is only in contact with the housing 1 through the second support structure 5, further reducing the contact area and allowing it to be suspended within the housing 1, forming a heat insulation gap. Air has low thermal conductivity, thus significantly reducing heat transfer through the heat insulation gap. Simultaneously, the heat insulation plate assembly 3 surrounds the outside of the cooking section 2, achieving comprehensive heat insulation for it.

[0060] like Figure 3 As shown, in some embodiments, optionally, the first support structure 4 includes a bracket 40 located between the cooking section 2 and the heat insulation plate assembly 3, wherein the cooking section 2 is supported within the heat insulation plate assembly 3 by the bracket 40, so that the cooking section 2 and the heat insulation plate assembly 3 are spaced apart.

[0061] In this embodiment, the first support structure 4 includes a bracket 40, which is located between the cooking section 2 and the heat insulation plate assembly 3, thus creating a heat insulation gap between them. Since the temperature inside the cooking cavity 24 is high when the cooking section 2 is working, this heat insulation gap between the heat insulation section and the heat insulation plate assembly 3 improves the heat insulation effect. It is understood that the bracket 40 has a small support area, thereby reducing the contact area between the heat insulation plate assembly 3 and the cooking section 2, which helps to reduce heat transfer from the cooking section 2 to the heat insulation plate assembly 3.

[0062] Optionally, the heat insulation gap between the cooking section 2 and the heat insulation plate assembly 3 surrounds the outside of the cooking section 2 and avoids the opening 20.

[0063] In some embodiments, optionally, one end of the bracket 40 is supported on the heat insulation plate assembly 3 in the vertical direction, and the other end is connected to the cooking part 2.

[0064] In this embodiment, the two ends of the bracket 40 along the vertical direction are respectively supported between the heat insulation plate assembly 3 and the cooking part 2, which can improve the support effect of the bracket 40 on the cooking part 2 and ensure the stability and reliability of the cooking part 2.

[0065] like Figure 3 As shown, in some embodiments, optionally, the cooking section 2 is provided with first flanges 22 on opposite sides along the first direction, and the support 40 is located on both sides of the cooking section 2 along the first direction; in the vertical direction, one end of the support 40 is supported on the bottom of the first flange 22, and the other end of the support 40 is connected to the heat insulation plate assembly 3.

[0066] In this embodiment, the cooking section 2 has first flanges 22 on both sides along the first direction. One end of the bracket 40 is supported on the bottom of the first flanges 22, and the other end is connected to the heat insulation plate assembly 3, thus supporting the cooking section 2. At the same time, the heat insulation plate assembly 3 contacts the first flanges 22 through the bracket 40, which can reduce the heat transfer from the cooking section 2 to the heat insulation plate assembly 3. Furthermore, the first flanges 22 are located on both sides of the cooking section 2 along the first direction, so that the bracket 40 is located on both sides of the cooking section 2 along the first direction, thereby reducing the space occupied by the bracket 40 in the vertical direction and reducing the height of the cooking appliance in the vertical direction.

[0067] Optionally, the bottom of the cooking section 2 is provided with a heating component, and the first flange 22 is positioned to avoid the heating component in order to reduce the temperature value at the first flange 22.

[0068] It is understandable that there are multiple supports 40, which are positioned close to the bottom of the housing 1 to ensure the stability of the cooking unit 2.

[0069] Optionally, the first flange 22 and the cooking cavity 24 of the cooking section 2 are an integral structure.

[0070] like Figure 1 As shown, in some embodiments, optionally, the cooking part 2 includes: a cooking cavity 24, the cooking cavity 24 having an opening 20 on one side along a second direction; a baffle 26 connected to the cooking cavity 24 and surrounding the periphery of the opening 20, the baffle 26 being connected to the housing 1; wherein, the second support structure 5 includes a second flange 50 and a third flange 52, the second flange 50 being located on the side of the heat insulation plate assembly 3 near the opening 20, the third flange 52 being located on the side of the heat insulation plate assembly 3 away from the opening 20, the second flange 50 being connected to the baffle 26, and the third flange 52 being connected to the housing 1.

[0071] In this embodiment, the cooking section 2 includes a cooking cavity 24 and a baffle 26. The cooking cavity 24 has an opening 20, and the baffle 26 surrounds the opening 20 and is connected to the housing 1. The second support structure 5 includes a second flange 50 and a third flange 52. The heat insulation plate assembly 3 is connected to the baffle 26 via the second flange 50, and the baffle 26 is connected to the housing 1, thereby supporting the front end of the heat insulation plate assembly 3 along the second direction on the housing 1. Simultaneously, the heat insulation plate assembly 3 is connected to the housing 1 via the third flange 52, thereby supporting the rear end of the heat insulation plate assembly 3 along the second direction within the housing 1. The installation of the heat insulation plate assembly 3 and the housing 1 is achieved through the second flange 50 and the third flange 52, improving the connection stability between the heat insulation plate assembly 3 and the housing 1. Furthermore, the second flange 50 and the third flange 52 can reduce the indirect contact area between the heat insulation plate assembly 3 and the housing 1, which helps to reduce the heat transferred from the heat insulation plate assembly 3 to the housing 1, thereby reducing the temperature rise of the housing 1.

[0072] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, optionally, the housing 1 includes: a cover 10, which covers the outside of the cooking cavity 24 and is connected to the baffle 26; a back plate 12, which is located at one end of the cover 10 away from the baffle 26 in a second direction, and the heat insulation plate assembly 3 is connected to the back plate 12 via a third flange 52; and a bottom plate 14, which is located at the bottom of the cooking section 2, with the bottom of the back plate 12 supported on the bottom plate 14, and the bottom of the baffle 26 connected to the bottom plate 14.

[0073] In this embodiment, the housing 1 includes a cover 10, a back plate 12, and a bottom plate 14. The cover 10 covers the outside of the cooking cavity 24 and is connected to the baffle 26. The back plate 12 is located on the side of the cooking cavity 24 away from the opening 20 along the second direction and is connected to the cover 10. The bottom plate 14 is located at the bottom of the cooking cavity 24 and is connected to the cover 10, the baffle 26, and the back plate 12. Thus, the cover 10, the back plate 12, and the bottom plate 14 surround the cooking section 2. The heat insulation plate assembly 3 is connected to the back plate 12 via a third flange 52. The bottom of the back plate 12 is supported by the bottom plate 14, thereby fixing the two ends of the heat insulation plate assembly 3 along the second direction and reducing the contact area between other parts of the heat insulation plate assembly 3 and the housing 1, thereby improving the heat insulation effect.

[0074] Optionally, the cover 10 is located at the top of the cooking section 2 in the vertical direction and on both sides of the cooking section 2 in the first direction.

[0075] In some embodiments, the bottom plate 14 is optionally provided with a support rib 142, and the bottom of the back plate 12 is supported by the support rib 142.

[0076] In this embodiment, the bottom plate 14 is provided with a support rib 142, and the bottom of the back plate 12 is supported by the support rib 142. That is, the heat insulation plate assembly 3 is connected to the back plate 12 through the third flange 52, and the back plate 12 is supported by the support rib 142 on the bottom plate 14. While fixing the heat insulation plate assembly 3, the heat insulation plate assembly 3 and the back plate 12 are in small-area contact, and the back plate 12 and the bottom plate 14 are in small-area contact, which greatly reduces the heat transfer between the heat insulation plate assembly 3 and the shell 1 and improves the heat insulation effect.

[0077] In some embodiments, the support rib 142 is optionally arranged in a strip shape and extends along a second direction. In this embodiment, the support rib 142 is a strip structure extending along the second direction, thereby reducing the contact area between the back plate 12 and the support rib 142, which can reduce the amount of heat transfer between the heat insulation panel assembly 3 and the bottom plate 14.

[0078] like Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the back plate 12 includes: a first back plate 120, disposed on the side of the cooking section 2 away from the opening 20 along the second direction, the heat insulation plate assembly 3 being connected to the first back plate 120 via a third flange 52, the bottom plate 14 being provided with a support rib 142, and the end of the first back plate 120 being supported by the support rib 142; and a second back plate 122, disposed on the side of the first back plate 120 away from the opening 20 and spaced apart from the first back plate 120.

[0079] In this embodiment, the back plate 12 includes a first back plate 120 and a second back plate 122. Both the first back plate 120 and the second back plate 122 are located on the side of the cooking section 2 away from the opening 20 along the second direction, and the second back plate 122 is located outside the first back plate 120. The heat insulation plate assembly 3 is connected to the first back plate 120 through a third flange 52. The first back plate 120 is supported on the support ribs 142 of the base plate 14, thereby fixing the heat insulation plate assembly 3 and extending the path of heat transfer from the heat insulation plate assembly 3 to the outside, thus improving the heat insulation effect. The second back plate 122 is spaced apart from the first back plate 120, which can also block the heat generated by the cooking section 2. At the same time, electrical components can be installed in this interval, reducing the space occupied by the cooking appliance in the height and left and right directions.

[0080] In some embodiments, the cooking appliance may optionally include an electrical control box 6 disposed between the first back panel 120 and the second back panel 122.

[0081] In this embodiment, the control box 6 is positioned between the first back plate 120 and the second back plate 122, which keeps the temperature of the control box 6 low and also avoids occupying other space of the cooking appliance.

[0082] like Figure 1 As shown, in some embodiments, optionally, the cooking appliance further includes: a fan 7, disposed between the first back plate 120 and the second back plate 122, the cover 10 and the heat insulation plate assembly 3 enclosing a channel 18, one end of the fan 7 being connected to the channel 18, and the other end of the fan 7 being connected to the electrical control box 6; wherein, the housing 1 is provided with an air inlet 16, the channel 18 is provided with an air outlet 28, and the electrical control box 6 is connected to the air inlet 16, and when the fan 7 is turned on, the airflow flows from the air inlet 16 through the electrical control box 6 and then out of the channel 18 through the air outlet 28.

[0083] In this embodiment, the fan 7 is disposed between the first back plate 120 and the second back plate 122. When the fan 7 is turned on, the airflow enters the electrical control box 6 through the air inlet 16 on the housing 1, and flows out of the channel 18 through the air outlet 28 after passing through the electrical control box 6, thereby achieving heat dissipation for the electrical control box 6 and the cooking part 2.

[0084] Optionally, the fan 7 is installed on the top of the electrical control box 6. The top of the housing 1 and the heat insulation plate assembly 3 enclose a channel 18. The electrical control box 6 is connected to the air outlet 28 and the fan 7, so that the airflow enters the electrical control box 6, passes through the fan 7 and the channel 18, and flows out of the air outlet 28, thereby carrying away the heat from the power board inside the electrical control box 6 and the heat from the cooking section 2.

[0085] like Figure 1 As shown, in some embodiments, optionally, the base plate 14 is provided with heat dissipation holes 140, which are located on the side of the electrical control box 6 away from the air inlet 16.

[0086] In this embodiment, the base plate 14 is provided with heat dissipation holes 140, which enable natural heat dissipation and improve the cooking effect of the cooking appliance. At the same time, the heat dissipation holes 140 and the air inlet 16 are located on both sides of the electrical control box 6. The electrical control box 6 can isolate the heat from the heat dissipation holes 140, preventing the heat from the bottom of the cooking section 2 from flowing to the electrical control box 6 under the action of the fan 7, thus ensuring the heat dissipation effect of the electrical components inside the electrical control box 6.

[0087] Optionally, the bottom end of the electrical control box 6 abuts against the bottom plate 14 of the housing 1.

[0088] Optionally, the bottom of the control box 6 is sealed to the bottom plate 14 of the housing 1 to prevent heat from the bottom of the cooking section 2 from entering the control box 6 under the action of the fan 7.

[0089] Optionally, the heat insulation panel assembly 3 can be a one-piece molded structure or it can be spliced ​​together from multiple heat insulation panels 30.

[0090] like Figure 1 and Figure 7 As shown, in some embodiments, optionally, the heat insulation plate assembly 3 includes a plurality of heat insulation plates 30; at least two heat insulation plates 30 are respectively located on both sides of the cooking section 2 along the vertical direction, at least one heat insulation plate 30 is located on the side of the cooking section 2 away from the opening 20 along the second direction, and at least two heat insulation plates 30 are respectively located on both sides of the cooking section 2 along the first direction; wherein, the heat insulation plate 30 located at the top of the cooking section 2 and the heat insulation plate 30 located on the side of the cooking section 2 away from the opening 20 together form a third flange 52, and the heat insulation plate 30 located at the bottom of the cooking section 2 is provided with a second flange 50 on the side of the cooking section 2 near the opening 20 along the second direction.

[0091] In this embodiment, the heat insulation plate assembly 3 includes multiple heat insulation plates 30, which surround the cooking section 2 on both sides along the vertical direction, both sides along the first direction, and the side of the cooking section 2 away from the opening 20 along the second direction, achieving all-round heat insulation for the cooking section 2 and improving the heat insulation effect. At the same time, the heat insulation plate 30 located at the top of the cooking section 2 and the heat insulation plate 30 located on the side of the cooking section 2 away from the opening 20 together form a third flange 52, which is used to connect with the back plate 12 of the housing 1, reducing the number of parts used and reducing the assembly difficulty; the heat insulation plate 30 located at the bottom of the cooking section 2 has a second flange 50 on the side along the second direction near the opening 20, which realizes the fixation of the front end of the heat insulation plate assembly 3.

[0092] Optionally, the third flange 52 and the heat insulation board 30 are an integral structure.

[0093] Optionally, the first direction is the left-right direction of the cooking utensil, and the second direction is the front-back direction of the cooking utensil.

[0094] Optionally, the vertical direction, the first direction, and the second direction are perpendicular to each other.

[0095] Optionally, there may be multiple second flanges 50, and the multiple second flanges 50 are spaced apart along the first direction.

[0096] Optionally, there are two second flanges 50. The arrangement of two second flanges 50 reduces the contact area between the heat insulation panel assembly 3 and the baffle 26.

[0097] In some embodiments, optionally, the cover 10 and the heat insulation panel assembly 3 are spaced apart; and / or the back plate 12 and the heat insulation panel assembly 3 are spaced apart; and / or the bottom plate 14 and the heat insulation panel assembly 3 are spaced apart.

[0098] In this embodiment, the cover 10 and the heat insulation plate assembly 3 are spaced apart, and / or the back plate 12 and the heat insulation plate assembly 3 and / or the bottom plate 14 and the heat insulation plate assembly 3 are spaced apart, which helps to prevent heat from being transferred to the outside.

[0099] Optionally, the cover 10 and the heat insulation board assembly 3, the back plate 12 and the heat insulation board assembly 3, and the bottom plate 14 and the heat insulation board assembly 3 are all spaced apart.

[0100] like Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the cooking appliance may optionally include: a heat insulation cotton assembly 8, which is wrapped around the outer wall of the cooking part 2 and disposed to avoid the opening 20, and is located between the cooking part 2 and the heat insulation plate assembly 3 and spaced apart from the heat insulation plate assembly 3.

[0101] In this embodiment, the cooking appliance also includes a heat insulation cotton assembly 8, which is wrapped around the outer wall of the cooking section 2 and positioned to avoid the opening 20, thereby insulating the cooking section 2. The heat insulation cotton assembly 8 is lightweight and, when combined with the heat insulation plate assembly 3, can improve the heat insulation effect. Furthermore, the heat insulation cotton assembly 8 and the heat insulation plate assembly 3 are spaced apart, which can further enhance the heat insulation effect.

[0102] In some embodiments, optionally, the thickness of the portion of the heat insulation cotton assembly 8 away from the opening 20 along the second direction is a first thickness, and the thickness of the portion of the heat insulation cotton assembly 8 corresponding to the periphery of the cooking part 2 is a second thickness, wherein the first thickness is greater than the second thickness.

[0103] In this embodiment, the first thickness is greater than the second thickness, that is, the thickness of the heat insulation cotton component 8 along the second direction on the back of the cooking part 2 is larger, which can improve the heat insulation effect on the back of the cooking part 2, thereby ensuring the working reliability of the control system (e.g., control box) of the cooking appliance.

[0104] like Figure 3 ,Figure 5 and Figure 6 As shown, in some embodiments, optionally, the heat insulation cotton assembly 8 includes a first heat insulation cotton 80, which surrounds both sides of the cooking section 2 along the vertical direction and the side of the cooking section 2 away from the opening 20 along the second direction; and a second heat insulation cotton 82, which surrounds both sides of the cooking section 2 along the first direction and the side of the cooking section 2 away from the opening 20 along the second direction, with the first heat insulation cotton 80 and the second heat insulation cotton 82 stacked on the side of the cooking section 2 away from the opening 20 along the second direction.

[0105] In this embodiment, the heat insulation cotton assembly 8 includes a first heat insulation cotton 80 and a second heat insulation cotton 82. The first heat insulation cotton 80 surrounds both sides of the cooking part 2 along the vertical direction and the side away from the opening 20 along the second direction. That is, the first heat insulation cotton 80 extends from one side of the cooking part 2 along the vertical direction towards the back of the cooking part 2 along the second direction, and after passing the back of the cooking part 2, it extends from the other side of the cooking part 2 along the vertical direction towards the opening 20 of the cooking part 2, thus wrapping the cooking part 2. The second heat insulation cotton 82 is located on both sides of the cooking part 2 along the first direction and the side away from the opening 20 along the second direction. That is, the second heat insulation cotton 82 extends from one side of the cooking part 2 along the first direction towards the back of the cooking part 2 along the second direction, and after passing the back of the cooking part 2, it extends from the other side of the cooking part 2 along the first direction towards the opening 20 of the cooking part 2. Thus, the first heat insulation cotton 80 and the second heat insulation cotton 82 are arranged in a cross shape, thereby providing at least two layers of heat insulation cotton structure on the back of the cooking part 2, improving the heat insulation effect of the back of the cooking part 2.

[0106] Alternatively, the cooking appliance may include an oven, such as a pizza oven.

[0107] According to one embodiment of this application, a pizza oven heat insulation solution is proposed to reduce heat transfer from the high-temperature cavity (e.g., cooking cavity 24) to the surface of the outer shell (e.g., housing 1) and the power board control assembly (e.g., electrical control box 6), thereby reducing the surface temperature of the pizza oven's outer shell and providing a low-temperature environment for the power board control assembly to ensure reliable operation of the power board control assembly.

[0108] The pizza oven insulation solution proposed in this application is as follows: the upper, lower, left, right, and rear surfaces of the cavity are all wrapped with insulation cotton (e.g., insulation cotton assembly 8), and the insulation cotton is surrounded by an insulation plate assembly 3, which consists of five surfaces: upper, lower, left, right, and rear. The cavity assembly is suspended and connected to the insulation plate assembly 3 through a cavity support (e.g., support 40) via point contact, reducing heat transfer to the outside. The insulation plate assembly 3 is also suspended and connected to the inner rear plate (e.g., the first back plate 120) via point contact, and then fixedly connected to the bottom plate 14 via point contact. The suspended state of the cavity assembly and the insulation plate assembly 3, and the point contact (small area contact) method, effectively reduce heat transfer.

[0109] Space gaps (e.g., heat insulation gaps) are reserved between the heat insulation panel assembly 3 and the outer cover, between the heat insulation panel assembly 3 and the bottom plate 14, and between the heat insulation panel assembly 3 and the inner rear plate, which helps to prevent heat from being transferred outward. The heat insulation cotton assembly 8 is composed of two pieces of heat insulation cotton (e.g., the first heat insulation cotton 80 and the second heat insulation cotton 82) in a cross-shaped manner. The intersection point is at the rear of the cavity, which means that the heat insulation cotton at the rear of the cavity is double-layered, further effectively preventing heat from being transferred to the rear, which is beneficial to the reliability of the rear control system of the pizza oven.

[0110] When the high temperature inside the cavity is transferred to the surrounding areas, it sequentially passes through the cavity, the insulation cotton assembly 8, the insulation plate assembly 3, and the insulation gap between the insulation plate assembly 3 and the outer shell and / or bottom plate 14. When the high temperature inside the cavity is transferred to the rear, it sequentially passes through the cavity, the insulation cotton assembly 8, the insulation plate assembly 3, the insulation gap between the insulation plate assembly 3 and the inner rear plate, and the gap between the inner rear plate and the outer rear plate, to the outer rear plate. This multi-layer insulation system ensures that the outer surface of the pizza oven does not experience dangerous conditions such as high temperatures.

[0111] The cooking appliance proposed in this application features a suspended cavity and a point-contact (small-area contact) design for both the cavity and the heat insulation assembly 3, effectively reducing heat transfer from the cavity to the outside. Spatial gaps (e.g., insulation gaps) are provided between the heat insulation assembly 3 and the outer cover, the bottom plate 14, and the inner rear plate, which helps to prevent heat transfer outwards. Simultaneously, the multi-layer insulation system ensures that dangerously high temperatures do not occur on the outer surface of the pizza oven.
