Meanwhile, heat insulation box 41 synchronously as control subassembly 30's control box, need no longer configure control box, and no longer adopt fan, can reduce noise, reduce cost and reduce the volume.

[0034] As Figure 8 Indicated in the utility model, the door body subassembly 1 of the application is a furnace door of a cooking appliance, and the control structure of the corresponding cooking appliance is at least partially arranged on the door body subassembly 1, such as a furnace door of a steaming and baking device with a control function, a furnace door of an oven with a control function, etc.

[0035] As Figure 1 and Figure 2The frame of the door body assembly 1 comprises a door outer frame 10 and a door lining plate 20, and the door body assembly 1 further comprises a stove door glass, and the door outer frame 10 is provided with a window for fixing the stove door glass. Specifically, the stove door glass comprises an outer glass 70 and an inner glass 80, and the door lining plate 20 is an inner plate close to the cabinet of the cooking appliance, and the outer glass 70 is arranged on the outer side of the door outer frame 10. The window is used for placing the inner glass 80, and the inner glass 80 is fixed between the door outer frame 10 and the door lining plate 20. Wherein, the outer glass 70 and the inner glass 80 are both high-temperature-resistant glass, such as high-boron material glass. In the utility model, for the door outer frame 10, the outer side refers to the side of the door outer frame 10 away from the door lining plate 20, and the inner side refers to the side of the door outer frame 10 close to the door lining plate 20, and the inner wall in the following refers to the wall surface close to the door lining plate 20, which will not be explained hereinafter.

[0036] The door outer frame 10 and the door lining plate 20 are fixedly connected, and the inside of the door outer frame 10 and the door lining plate 20 is formed with a cavity 11 for placing the control assembly 30 and the heat insulation assembly 40. The cavity 11 can also be provided with a connecting structure for connecting with the cooking cabinet 2, which is not the innovation point of the utility model, and will not be described here. In the utility model, the heat insulation assembly 40 and the control assembly 30 are arranged below the window, that is, the control assembly 30 is arranged on the lower side of the inner glass 80; in other embodiments, the control assembly 30 of the door body assembly 1 can also be arranged on the side of the window, that is, the control assembly 30 is arranged on the left side or the right side of the outer glass 70.

[0037] In combination with Figure 3 The control assembly 30 comprises a control panel 311 and a control button 312, the control button 312 is electrically connected with the control panel 311, the control button 312 is used for controlling the running state of the cooking appliance, the control panel 311 is arranged on the inner wall of the door outer frame 10, and the control button 312 can comprise a control knob or a control button 312 penetrating through the outer glass 70 and the door outer frame 10, or be a touch button arranged on the outer glass 70, which is not limited here.

[0038] The heat insulation box 41 is a box-shaped structure prepared by using heat insulation material, since the control panel 311 is arranged on the inner wall of the door outer frame 10, the heat insulation box 41 and the inner wall of the door outer frame 10 form a heat insulation chamber, so that heat is prevented from being transmitted to the control assembly 30. Further, a heat insulation layer 42 is arranged between the heat insulation box 41 and the door lining plate 20, when the heat of the cooking appliance is transmitted to the door body assembly 1, the heat received by the control assembly 30 is greatly reduced under the double barrier effect of the heat insulation layer 42 and the heat insulation box 41, so that the control assembly 30 can be prevented from being affected by the heating of the cooking assembly.

[0039] The control assembly 30 and the inner wall of the heat insulation box 41 are left with a gap, and the corresponding gap forms a natural heat insulation layer 42, which reduces the heat of the heat insulation box 41 to the control assembly 30 again. At the same time, the heat generated by the control assembly 30 during operation can circulate in the gap, helping the control assembly 30 to dissipate heat. The gap is also convenient for installation and maintenance between the control assembly 30 and the heat insulation box 41.

Of course, the heat insulation box 41 can also be fixed to the door lining plate 20.

[0042] The heat insulation box 41 of the utility model is made of high-temperature-resistant PBT material. PBT refers to polybutylene terephthalate, which is a polyester made of terephthalic acid and 1,4-butanediol. It is an important thermoplastic polyester, which has high heat resistance and high flame retardance. Compared with the existing control box made of ABS material, the PBT material has better heat insulation and heat resistance, and can effectively reduce the heat transfer to the control assembly 30. The heat insulation box 41 can also be made of other phenyl silicone rubber materials, and more preferably can be made of medium-phenyl silicone rubber with a phenyl content of 15-25% and high-phenyl silicone rubber with a phenyl content of more than 30%. The heat insulation box 41 can also be made of polyimide material.

In the utility model, in order to guarantee that the heat insulation box 41 can effectively fix the heat insulation layer 42, the depth of the recess 43 of the heat insulation box 41 is at least one fourth of the thickness of the heat insulation layer 42, that is, the protruding range of the heat insulation layer 42 does not exceed three fourths of its thickness, and the exceeding part of the heat insulation layer 42 can be one fourth, one half or one fourth of its thickness, preferably one fourth, so that the heat insulation layer can be placed in the recess 43 and not too much part protrudes, and the increase of the heat insulation box 41 is avoided.

[0047] And the thickness of the heat insulation layer 42 is greater than the depth of the recess 43, which can improve the heat absorption and blocking capacity of the heat insulation layer 42, thereby effectively reducing the heat transfer to the heat insulation box 41. Further, the heat insulation layer 42 comprises heat insulation cotton, which has excellent heat insulation performance and can effectively absorb and block the heat transfer, thereby protecting the control assembly 30 from high temperature. In other embodiments, the heat insulation layer 42 can be a foamed plastic layer.

The clamping structure 60 is a protruding block in this scheme, the protruding block is protrudingly arranged on the top plate 411 of the heat insulation box 41, and the protruding block abuts with the hook part of the elastic clamping hook 51. When the heat insulation box 41 is subjected to force, the protruding block pushes the hook part of the elastic clamping hook 51, and the force of the elastic clamping hook 51 offsets the force of the elastic clamping hook 51 away from the door outer frame 10, so that the heat insulation box 41 is fixed. In other embodiments, the clamping structure 60 can be a clamping piece clamped with the elastic clamping hook 51, specifically a clamping hook with a hook part, or the clamping structure 60 is a buckle position, and the left and right of the elastic clamping hook 51 and the buckle position are used to lock the heat insulation box 41.
