[0045] The exterior of the cooking chamber of a conventional household cooking device, such as an oven or a microwave oven, is covered with heat-insulating materials, such as fiberglass insulation, ceramic fiber insulation or aerogel insulation. However, even with the use of heat-insulating materials, the heat in the cooking chamber will still be lost through the heat-insulating materials and raise the temperature of the outer surface of the cooking device, thus easily causing scalding.

[0046] In order to solve the problem of the outer surface temperature of the cooking device increasing due to heat loss in the cooking cavity, the present application proposes a cooking device that can effectively reduce the heat overflow in the cooking cavity, thereby lowering the outer surface temperature of the cooking device and reducing the occurrence of scalding.

[0047] The cooking device in the present application may include a cooking device with a cooking cavity such as an oven or a microwave oven. For the convenience of description, the embodiments of the present application only use an oven in the shape of a square shell as an example of the cooking device.

[0048] Combine Figures 1 to 4 As shown, in some embodiments of the present application, the cooking device 100 includes a first shell 10, a second shell 20 and an insulation assembly 30, the first shell 10 is provided with an installation cavity 11, the second shell 20 is provided in the installation cavity 11, the second shell 20 is provided with a cooking cavity 21, the insulation assembly 30 is provided between the inner wall surface of the first shell 10 and the outer surface of the second shell 20, and includes a first insulation member 31 and a second insulation member 32, the first insulation member 31 is sleeved on the outside of the second shell 20, the second insulation member 32 is sleeved on the outside of the first insulation member 31, and at least part of the outer surface of the second insulation member 32 is spaced apart from the inner wall surface of the first shell 10.

[0049] In some embodiments of the present application, the first housing 10 is a square shell-shaped structure and forms the overall exterior structure of the cooking device 100. When a user operates the cooking device 100, the side facing the user is the front, the side facing away from the user is the back, the side on the user's left hand side is the left side, and the side on the user's right hand side is the right side. The first housing 10 has a length direction X, a width direction Y, and a height direction Z. The distance between the left and right sides is the length direction X of the first housing 10, i.e., the length direction of the cooking device 100, and the distance between the front and back sides is the width direction Y of the first housing 10, i.e., the width direction of the cooking device 100. The height direction Z of the first housing 10 is aligned with the vertical direction, i.e., the height direction of the cooking device 100 is aligned with the vertical direction. The first housing 10 is a hollow structure, with an interior formed with a mounting cavity 11. The second housing 20 is disposed within the mounting cavity, and a cooking cavity 21 is formed within the interior of the second housing 20. A first opening 121 is provided on the front of the first housing 10 along its width direction Y. The first opening 121 communicates with the cooking cavity 21. Food can be placed into the cooking cavity 21 through the first opening 121 for heating. Alternatively, after heating in the cooking cavity 21, the food can be removed from the cooking cavity 21 through the first opening 121.

[0050] Optionally, the first housing 10 includes a front side plate 12, a first rear side plate 131, a bottom plate 14, a top plate 15, a left side plate 16, and a right side plate 17. The front side plate 12, the first rear side plate 131, the bottom plate 14, the top plate 15, the left side plate 16, and the right side plate 17 enclose an installation cavity 11. Among them, the front side plate 12 and the first rear side plate 131 are respectively arranged on the front and rear sides of the first housing 10 along the width direction Y of the first housing 10, the top plate 15 and the bottom plate 14 are respectively arranged on the upper and lower sides of the first housing 10 along the height direction Z of the first housing 10, and the left side plate 16 and the right side plate 17 are respectively arranged on the left and right sides of the first housing 10 along the length direction X of the first housing 10. Among them, a first opening 121 is provided through the front side plate 12. The cooking device 100 further includes a door body 40. The door body 40 is arranged on the front side of the front side plate 12 and is configured to open or close the first opening 121. In some embodiments of the present application, the cooking device 100 further includes a front cover plate 18. The front cover plate 18 is arranged on the front side of the front side plate 12 and is arranged on the upper and lower sides of the door body 40 in the vertical direction, and the front end surface of the front cover plate 18 is flush with the front end surface of the door body 40. Thus, when the door body 40 is in the state of closing the first opening 121, the door body 40 is located between the front cover plates 18 on the upper and lower sides, thereby improving the overall appearance of the cooking device 100.

[0051] Since heat is generated in the cooking cavity 21 during the heating process, in order to reduce the heat in the cooking cavity 21 from flowing into the installation cavity 11 through the second housing 20, resulting in an increase in the outer surface temperature of the first housing 10, the cooking device 100 in the present application further includes a heat insulation assembly 30. The heat insulation assembly 30 is arranged between the inner wall surface of the first housing 10 and the outer surface of the second housing 20, that is, the heat insulation assembly 30 is arranged in the installation cavity 11 to reduce the heat conduction from the cooking cavity 21 to the first housing 10. Among them, the heat insulation assembly 30 is a double-layer structure, including a first heat insulation member 31 and a second heat insulation member 32. The first heat insulation member 31 is sleeved outside the second housing 20, the second heat insulation member 32 is sleeved outside the first heat insulation member 31, and at least part of the outer surface of the second heat insulation member 32 is spaced from the inner wall surface of the first housing 10. Optionally, the entire outer surface of the second heat insulation member 32 is spaced from the inner wall surface of the first housing 10. That is, the inner wall surface of the first rear side plate 131, the inner wall surface of the bottom plate 14, the inner wall surface of the top plate 15, the inner wall surface of the left side plate 16, and the inner wall surface of the right side plate 17 are respectively spaced from the outer surface of the second heat insulation member 32. Or, part of the outer surface of the second heat insulation member 32 is spaced from the inner wall surface of the first housing 10, that is, one or several of the inner wall surface of the first rear side plate 131, the inner wall surface of the bottom plate 14, the inner wall surface of the top plate 15, the inner wall surface of the left side plate 16, and the inner wall surface of the right side plate 17 have a fitting area with the second heat insulation member 32.

[0052] Among them, the first heat insulation member 31 is sleeved outside the second housing 20, including that the first heat insulation member 31 completely covers all the outer surfaces of the second housing 20 inserted into the installation cavity 11, or including that the first heat insulation member 31 does not completely cover all the outer surfaces of the second housing 20 inserted into the installation cavity 11. When the first heat insulation member 31 does not completely cover all the outer surfaces of the second housing 20 inserted into the installation cavity 11, a first reserved hole may be provided on the first heat insulation member 31 so that other components, such as conductive wires, can be passed through at a position corresponding to the first reserved hole outside the second housing 20. The second heat insulation member 32 is sleeved outside the first heat insulation member 31, including that the second heat insulation member 32 completely covers all the outer surfaces of the first heat insulation member 31, or including that the second heat insulation member 32 does not completely cover all the outer surfaces of the first heat insulation member 31. When a first reserved hole is provided on the first heat insulation member 31, a second reserved hole corresponding to the position of the first reserved hole is provided on the second heat insulation member 32 so that other components can be arranged outside the second housing 20 and the other components pass through the first reserved hole and the second reserved hole in sequence, such as conductive wires.

[0053] For the cooking device 100 according to the present application, by sleeving the first heat insulation member 31 outside the second housing 20 and sleeving the second heat insulation member 32 outside the first heat insulation member 31, a two-layer heat insulation structure is formed outside the cooking cavity 21, which can effectively reduce the heat transfer from the cooking cavity 21 to the installation cavity 11. At the same time, since at least part of the outer surface of the second heat insulation member 32 is spaced from the inner wall surface of the first housing 10, the heat of the second heat insulation member 32 can be directly conducted to the first housing 10, thereby reducing the outer surface temperature of the cooking device 100 and reducing the occurrence of scalding.

[0054] Combined with Figures 1 to 4 As shown, in some embodiments of the present application, the inner wall surface of the first heat insulation member 31 fits the outer surface of the second housing 20, and the inner wall surface of the second heat insulation member 32 fits the outer surface of the first heat insulation member 31.

[0055] In some embodiments of the present application, by sequentially fitting the second housing 20, the first heat insulation member 31 and the second heat insulation member 32, the occupied space of the heat insulation assembly 30 in the installation cavity 11 can be reduced, thereby correspondingly increasing the occupied space of the second housing 20 in the installation cavity 11, that is, increasing the space of the cooking cavity 21 and improving the cooking ability of the cooking device 100. Or, the overall size of the first housing 10 can be correspondingly reduced, that is, the overall size of the cooking device 100 is reduced, and the occupied space of the cooking device 100 is reduced.

[0056] Combined with Figures 1 to 4 As shown, in some embodiments of the present application, the first heat insulation member 31 includes heat insulation cotton, and the second heat insulation member 32 includes a heat insulation board.

[0057] Optionally, the heat insulation cotton may include fiberglass heat insulation cotton, ceramic fiber heat insulation cotton or aerogel heat insulation cotton. The heat insulation cotton has good deformability, so as to adapt to the shape of the second housing 20 and cover the outer surface of the second housing 20. The heat insulation board has good support performance. By arranging the heat insulation board on the side of the heat insulation cotton away from the second housing 20, the heat insulation cotton can be fixed on the outer surface of the second housing 20, and at the same time, the heat insulation component 30 has a regular outer surface, reducing the occupied space of the heat insulation component 30 in the installation cavity 11.

[0058] Combined with Figures 1 to 4 As shown, in some embodiments of the present application, the heat insulation component 30 further includes a first connecting member 33. One end of the first connecting member 33 is connected to the second heat insulation member 32, and the other end of the first connecting member 33 passes through the first heat insulation member 31 and is connected to the outer surface of the second housing 20.

[0059] In some embodiments of the present application, the first connecting member 33 may be a columnar structure. One end of the columnar structure is connected to the second heat insulation member 32, which may be welding. The other end of the columnar structure passes through the first heat insulation member 31 and is connected to the outer surface of the second housing 20, which may be welding, so as to fixedly connect the second heat insulation member 32 to the second housing 20, and further fix the heat insulation component 30 on the outer surface of the second housing 20.

[0060] Optionally, the first connecting member 33 may be arranged between the second housing 20 and the second heat insulation member 32 along the height direction Z of the first housing 10, including above or below the second housing 20. Or, the first connecting member 33 may be arranged between the second housing 20 and the second heat insulation member as shown in FIG. 11. Or, the first connecting member 33 may be arranged between the second housing 20 and the second heat insulation member 32 along the length direction X of the first housing 10, including on the left or right side of the second housing 20. Or, the first connecting member 33 may be arranged between the second housing 20 and the second heat insulation member 32 along the width direction Y of the first housing 10, including at the rear side of the second housing 20. As Figure 3 and Figure 4 As shown, the first connecting member 33 is arranged between the second housing 20 and the second heat insulation member 32 along the height direction Z of the first housing 10 and is arranged below the second housing 20. Optionally, the number of the first connecting members 33 may be multiple, and the multiple first connecting members 33 may be arranged at intervals and are respectively used to connect the second housing 20 and the second heat insulation member 32. The term "multiple" in the present application means two or more. As Figure 4 As shown, the number of the first connecting members 33 is two, the two first connecting members 33 are arranged below the second housing 20, and the two first connecting members 33 are arranged at intervals along the length direction X of the first housing 10.

[0061] Combined with Figures 1 to 4As shown, in some embodiments of the present application, the front side plate 12 is provided with a first opening 121 penetrating therethrough and communicating with the installation cavity 11. The second housing 20 is connected to the front side plate 12, and the first opening 121 communicates with the cooking cavity 21. At least one support member is further provided in the installation cavity 11, and the second heat insulation member 32 is connected to the inner wall surface of the first housing 10 through the support member.

[0062] In some embodiments of the present application, the front end of the second housing 20 is connected to the front side plate 12, including detachable connection or non-detachable connection. Among them, the detachable connection includes snap connection or connection through a connecting member, and the non-detachable connection includes welding. When the heat insulation assembly 30 is connected to the second housing 20, that is, when the second heat insulation member 32 is connected to the second housing 20 through the first heat insulation member 31, since the second housing 20 is inserted into the installation cavity 11 along the width direction Y of the first housing 10 and is only connected to the front side plate 12 through the front end of the second housing 20, it is easy to cause the end of the second housing 20 away from the first opening 121 to be unable to be effectively supported, resulting in sagging after long-term use and causing deformation or damage of the second housing 20. Therefore, in some embodiments of the present application, at least one support member is further provided in the installation cavity 11, and the support member is used to connect the inner wall surface of the first housing 10 and the second heat insulation member 32, thereby improving the support performance for the heat insulation assembly 30 and the second housing 20 and reducing the deformation and damage of the second housing 20. Alternatively, when the second heat insulation member 32 is not connected to the second housing 20 through the first heat insulation member 31, the second heat insulation member 32 can be connected to the inner wall surface of the first housing 10 through the support member, thereby fixing the second heat insulation member 32 in the installation cavity 11 and sleeving it outside the first heat insulation member 31.

[0063] Combined with Figures 1 to 4 As shown, in some embodiments of the present application, the support member includes a first support member 51, and the second heat insulation member 32 is connected to the inner wall surface of the first rear side plate 131 through the first support member 51.

[0064] In some embodiments of the present application, the second heat insulation member 32 is connected to the inner wall surface of the first rear side plate 131 through the first support member 51, thereby fixedly supporting the second heat insulation member 32 through the rear end of the second heat insulation member 32, and thus improving the fixed support effect on the heat insulation assembly 30.

[0065] Optionally, the number of the first support members 51 can be multiple. The multiple first support members 51 are spaced on the inner wall surface of the first rear side plate 131 facing the second housing 20 and are respectively used for fixedly connecting the second heat insulation member 32 and the first rear side plate 131. Optionally, the multiple first support members 51 are spaced along the length direction x of the first housing 10, and / or the multiple first support members 51 are spaced along the height direction Z of the first housing 10. As Figure 5As shown, there are two first support members 51 , which are spaced apart in the Z direction along the height direction of the first shell 10 and are used to connect the second heat insulating member 32 and the first rear side plate 131 respectively.

[0066] Combine Figures 1 to 3 As shown, in some embodiments of the present application, the first housing 10 further includes a second rear side panel 132, which is respectively connected to the rear end edges of the bottom panel 14, the top panel 15, the left side panel 16, and the right side panel 17, and together forms part of the exterior structure of the first housing 10. The first rear side panel 131 is provided on the side of the second rear side panel 132 facing the front side panel 12. The first rear side panel 131 is connected to the bottom panel 14, the top panel 15, the left side panel 16, and the right side panel 17, and together encloses the installation cavity 11. The first rear side panel 131 and the second rear side panel 132 are spaced apart along the width direction Y of the first housing 10, and a separation space is formed therebetween.

[0067] The cooking device 100 of the present application further includes an electric control panel assembly 60, which is disposed within the compartment. The electric control panel assembly 60 is used to control various operating states of the cooking device 100. The electric control panel assembly 60 generates heat during operation. Excessive temperature of the electric control panel assembly 60 can easily affect its operating state.

[0068] By locating the electronic control board assembly 60 within the space, it can be positioned outside the mounting cavity 11. Therefore, even if some heat from the cooking cavity 21 passes through the insulation assembly 30 and enters the mounting cavity 11, it does not cause a temperature rise in the electronic control board assembly 60, thereby improving the operational reliability of the electronic control board assembly 60. Furthermore, by arranging the second rear side panel 132 on the side of the first rear side panel 131 facing away from the mounting cavity 11, the interior of the first housing 10 is divided into a double-layered structure along the width direction Y by the first and second rear side panels 131, thereby reducing heat transfer from the cooking cavity 21 to the second rear side panel 132, thereby lowering the temperature rise of the second rear side panel 132 and reducing the risk of burns. Alternatively, the electronic control board assembly 60 can be connected to the surface of the first rear side panel 131 facing the second rear side panel 132, or to the surface of the second rear side panel 132 facing the first rear side panel 131.

[0069] In some embodiments of the present application, since the first rear side plate 131 is disposed between the second rear side plate 132 and the front side plate 12, a first support member 51 may be provided on the side of the first rear side plate 131 facing the second housing 20, and the first support member 51 may be connected to the second heat insulation member 32 to support the second heat insulation member 32. In some embodiments of the present application, the first rear side plate 131 may not be provided, and the installation cavity 11 may be enclosed by the front side plate 12, the second rear side plate 132, the bottom plate 14, the top plate 15, the left side plate 16, and the right side plate 17. At this time, a first support member 51 may be provided on the side of the second rear side plate 132 facing the second housing 20, and the first support member 51 may be connected to the second heat insulation member 32 to support the second heat insulation member 32.

[0070] Combined Figures 1 to 3 As shown, in some embodiments of the present application, an air inlet 71 communicating with the interval space is provided in the portion of the bottom plate 14 located between the first rear side plate 131 and the second rear side plate 132, and an air outlet 72 communicating with the interval space is provided at the top of the second rear side plate 132. A heat dissipation air duct 70 is formed between the air inlet 71 and the air outlet 72, and the electronic control board assembly 60 is disposed in the heat dissipation air duct 70.

[0071] By setting the interval space between the first rear side plate 131 and the second rear side plate 132 as the heat dissipation air duct 70, and providing the air inlet 71 and the air outlet 72 communicating with the heat dissipation air duct 70, the air flow outside the first housing 10 can flow into the heat dissipation air duct 70 through the air inlet 71, and flow out of the first housing 10 through the air outlet 72. During the flow of the air flow in the heat dissipation air duct 70, it can contact and exchange heat with the electronic control board assembly 60, so as to achieve the effect of cooling and dissipating heat of the electronic control board assembly 60 and improve the working reliability of the electronic control board assembly 60.

[0072] Optionally, the air inlet 71 may be provided on the bottom plate 14 and located in the portion between the first rear side plate 131 and the second rear side plate 132, and the air outlet 72 may be provided at the top of the second rear side plate 132, so as to form a heat dissipation air duct 70 with bottom air inlet and top air outlet between the first rear side plate 131 and the second rear side plate 132. At the same time, the air inlet 71 is provided on the bottom plate 14 near the first rear side plate 131. Compared with providing the air inlet 71 at the bottom of the second rear side plate 132 or providing the air inlet 71 on the bottom plate 14 near the second rear side plate 132, it can reduce the air flow in the heat dissipation air duct 70 from flowing out through the air outlet 72 and then directly flowing into the heat dissipation air duct 70 through the air inlet 71, thereby reducing the temperature of the intake air flow in the heat dissipation air duct 70. Optionally, the electronic control board assembly 60 may be disposed on the plate surface of the first rear side plate 131 facing the second rear side plate 132, so that the electronic control board assembly 60 can be disposed opposite to the air inlet 71 in the vertical direction, improving the heat dissipation effect of the intake air flow on the electronic control board assembly 60.

[0073] Combined Figure 1 and Figure 6 As shown, in some embodiments of the present application, the cooking device 100 further includes a cooling fan 80. The cooling fan 80 is disposed in the cooling air duct 70 and above the electronic control board assembly 60. The inlet of the cooling fan 80 faces the air inlet 71, and the outlet of the cooling fan 80 faces the air outlet 72.

[0074] By disposing the cooling fan 80 in the cooling air duct 70, the operation of the cooling fan 80 can accelerate the air flow in the cooling air duct 70, thereby improving the cooling effect on the electronic control board assembly 60. At the same time, by disposing the cooling fan 80 above the electronic control board assembly 60, that is, by disposing the electronic control board assembly 60 between the inlet of the cooling fan 80 and the air inlet 71, the cooling effect on the electronic control board assembly 60 can be improved.

[0076] In some embodiments of the present application, the second heat insulation member 32 is connected to the inner wall surface of the bottom plate 14 through the second support member 52, so as to fixedly support the second heat insulation member 32 from below the second heat insulation member 32, thereby improving the fixed support effect on the heat insulation assembly 30. Optionally, the second support member 52 can be disposed along the width direction Y of the first housing 10 on the side of the second heat insulation member 32 close to the first rear side plate 131, so as to improve the support effect on the second heat insulation member 32.

[0077] Optionally, the number of the second support members 52 can be multiple. The multiple second support members 52 are spaced on the inner wall surface of the bottom plate 14 and are respectively used for fixedly connecting the second heat insulation member 32 and the bottom plate 14. Optionally, the multiple second support members 52 are spaced along the length direction X of the first housing 10, and / or the multiple second support members 52 are spaced along the width direction Y of the first housing 10. As Figure 8 shown, the number of the second support members 52 is two. The two second support members 52 are spaced along the width direction Y of the first housing 10 and are respectively used for connecting the second heat insulation member 32 and the bottom plate 14.

[0078] Combined Figure 1 and Figure 9As shown, in some embodiments of the present application, the support member may simultaneously include a first support member 51 and a second support member 52. The first support member 51 is used to connect the second heat insulation member 32 and the first rear side plate 131, and the second support member 52 is used to connect the second heat insulation member 32 and the bottom plate 14, so as to support the rear end and the lower part of the second heat insulation member 32 respectively, and improve the support effect on the second heat insulation member 32.
