[0068] The upper support transverse plate 410 is connected to the upper position of the two support vertical beams 400 , and the lower support transverse plate 420 is connected to the lower position of the two support vertical beams 400 .

[0069] An upper air inlet portion 411 communicating with the inner cavity of the corresponding device is formed on the upper supporting horizontal plate 410 .

[0070] The upper support transverse plate 410 and the lower support transverse plate 420 are both fixed to the front side of the support vertical beam 400 by fasteners, and together with the support vertical beam 400 form a stable support frame structure.

[0071] The upper air inlet portion 411 formed on the upper supporting horizontal plate 410 is specifically an air inlet hole structure dispersedly formed on the upper supporting horizontal plate 410, which is used to realize the air duct in the inner cavity of the equipment and the gas circulation outside, thereby dissipating heat for electrical equipment such as the oven 100.

[0072] Specific reference Figure 5 In some embodiments of the present application, along the height direction of the supporting vertical beam 400, two layers of equipment cavity are formed between the top plate 200 and the bottom plate 600, the side plate 300 between the top plate 200 and the bottom plate 600 includes an upper side plate 310 and a lower side plate 320, and the back plate 500 includes an upper back plate 510 and a lower back plate 520, and the upper back plate 510 and the lower back plate 520 are detachably connected by fasteners.

[0073] Along the height direction of the outer supporting structure, there are two layers of equipment cavities, that is, each layer of the equipment cavity corresponds to an inner pot component, and each inner pot component can work independently to improve cooking efficiency.

[0074] Each layer of the equipment cavity corresponds to a set of side panels 300 and back panels 500. Compared with the upper and lower integrated form, the layered arrangement of the side panels 300 and back panels 500 is more conducive to improving the supporting strength of the external support structure.

[0075] Combine Figure 6In some embodiments of the present application, an intermediate support frame 330 is provided between the upper side plate 310 and the lower side plate 320 , and both the upper side plate 310 and the lower side plate 320 are connected to the intermediate support frame 330 .

[0076] Specific reference Figure 9 、 Figure 10 A supporting protrusion 710 extending toward the inner cavity of the device is also formed on the middle support frame 330.

[0077] The upper and lower sides of the middle support frame 330 are respectively connected and fixed to the upper side plate 310 and the lower side plate 320. The supporting protrusion 710 can provide support for the upper inner tank component. In addition to the connecting function, it also plays a supporting role.

[0078] Specifically, the middle support frame 330 is an integrally formed sheet metal structure, and connecting outer edges 332 are formed on both sides of the supporting protrusion 710. The connecting outer edges 332 are respectively connected and fixed to the upper side plate 310 and the lower side plate 320.

[0079] Both ends of the supporting protrusion 710 are also sealed by edge sealing 333 to prevent the inner cavity of the device from communicating with the outside world through the position of the supporting protrusion 710.

[0080] A press-molded portion 301 is further formed on the supporting protrusion 710 to improve the structural strength of the supporting protrusion 710 .

[0081] Combine Figure 6 、 Figure 7 In some embodiments of the present application, a supporting middle plate 430 is further provided between the two supporting vertical beams 400. The supporting middle plate 430 is provided between the upper supporting horizontal plate 410 and the lower supporting horizontal plate 420. A lower air inlet portion 431 communicating with the inner cavity of the corresponding equipment is formed on the supporting middle plate 430.

[0082] The lower air inlet portion 431 is specifically a penetrating air inlet hole dispersedly formed on the supporting middle plate 430 , and the air inlet hole is specifically in a shape of a long strip, a circle, an ellipse, or the like.

[0083] Both ends of the supporting middle plate 430 are widened to improve the connection strength with the supporting vertical beam 400.

[0084] The setting of the supporting middle plate 430 can, firstly, improve the stability of the two supporting vertical beams, and secondly, it corresponds to the inner cavity of the lower equipment, and the lower air inlet part 431 formed thereon can realize the circulation of external airflow with the inner cavity of the lower equipment.

[0086] The air outlet channel, the upper air inlet 411, the lower air inlet 431 and the rear air inlet are all used to connect with the air duct in the inner cavity of the device. The airflow in the air duct is used to dissipate heat for the electrical equipment in the inner cavity of the device. This part is the existing technology and is not the design focus of this application. It will not be described in detail here.

[0087] Combine Figure 2 In some embodiments of the present application, a press-formed portion 301 is formed on the side panel 300 to enhance the structural strength of the side panel 300 .

[0088] The specific shape and extension direction of the profiled portion 301 are designed according to actual needs. On each side panel 300 , the profiled portion 301 can be designed as a whole or can be designed as a plurality of profiled portions.

[0089] The side panels 300 on both sides of the device cavity can be universal to reduce the cost of design and forming.

[0090] refer to Figure 5 、 Figure 7 In some embodiments of the present application, decorative parts 700 are further provided on both sides of the supporting vertical beam. The decorative parts 700 are detachably connected to the outer side of the supporting vertical beam. The width of the decorative parts 700 is greater than the supporting vertical beam. The front and rear sides of the decorative parts extend to the outer side of the supporting vertical beam respectively, and are covered on the outside of the connection gap between the side panel 300 and the supporting vertical beam.

[0091] In some embodiments of the present application, a supporting protrusion 710 extending toward the supporting vertical beam is further formed on the decorative member 700. Under the action of the supporting protrusion 710, a gap is formed between the decorative member 700 and the supporting vertical beam, which is conducive to airflow and facilitates heat dissipation.

[0092] Combine Figure 3 In some embodiments of the present application, protective side panels 210 are respectively provided between the two side panels 300 and the top panel 200 , and an electrical room 201 is formed between the protective side panels 210 .

[0093] The rear side of the electrical room 201 is blocked by an extension portion 511 formed on the upper back plate 510 .

[0094] The electrical room 201 is used to place electrical equipment such as controllers. The protective side panels 210 are detachably connected to the side panels 300 and the top panel 200 via fasteners, which is beneficial to improving the supporting strength.

[0095] A profiled structure is also formed on the top plate 200 to increase strength and protect the top of the product. The protective side panels 210 and the top plate 200 together form a top structure, protecting the electrical components on the top like a cover.

[0096] In some embodiments of the present application, the upper back plate 510 located at the rear side of the outer support structure is a stepped structure, which provides space for installing a cooker above the oven 100.

[0097] The present application also proposes a built-in oven, which includes an oven body 100.

A control panel 110 is also arranged above the oven body 100 located on the top layer, and the control panel 110 is located on the front side of the electrical room 201.

[0098] The control panel 110 is connected to the controller in the electrical appliance room 201 , so that the user can conveniently control the corresponding cooking layer in the oven body 100 .

[0099] The front end of the bottom plate 600 is designed with a raised portion 331 to provide space for bottom air outlet. The middle of the bottom plate 600 adopts multiple ribs and profiles to increase strength while minimizing resistance to air outlet. It can also prevent internal water vapor from condensing and flowing out of the bottom plate 600 to a certain extent, which would bring a bad user experience.

[0100] The external support structure involved in this application is provided with two supporting beams 400 on the front side. It uses 1.5mm thick material and has extremely high strength, which also provides protection for the connection of other non-shell parts (oven door, oven panel, inner tank, etc.).

[0101] A fixing recess 401 opening toward the back panel 500 is formed on the supporting beam 400 , and the front side of the side panel 300 is connected to the fixing recess 401 , which can reduce the connection gap in the inner cavity of the equipment and improve its overall structural strength.

[0102] The device cavity between the top plate 200 and the bottom plate 600 has at least one layer. According to specific user needs, the oven body 100 can be designed with two or even multiple layers to achieve cooking zoning. The inner pots in different device cavities can work and cook independently without affecting each other, which is conducive to improving cooking efficiency.
