Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to fig. 6, the heating system under the inner container of the steaming and baking all-in-one machine of the embodiment includes an inner container 1, the bottom of the inner container 1 is provided with an inward concave portion 11 which is concave downwards, and the inward concave portion 11 is rectangular and is located in the middle area of the rear side of the bottom of the inner container 1. A lower positioning plate 2 is arranged below the outer bottom wall 12 of the inner container 1, the lower positioning plate 2 is fixed on the outer bottom wall 12 of the inner container 1 through a lower fixing plate bracket 7, and a mounting cavity 3 is reserved between the lower positioning plate 2 and the outer bottom wall 12 of the inner container.

The heating pipe at the bottom of the inner container 1 comprises a first heating pipe 4 and a second heating pipe 5 which work independently, the power of the first heating pipe 4 and the power of the second heating pipe 5 can be the same or different, different powers can be realized after the two heating pipes are arranged, and the heating process can be ensured to be continuous and uninterrupted.

The first heating pipe 4 and the second heating pipe 5 are taken as a component, wherein the first heating pipe 4 is located under the inner concave portion 11, the second heating pipe 5 is located under the region of the bottom of the liner except the inner concave portion 11, namely, the first heating pipe 4 is an inner heating pipe, and the second heating pipe 5 is an outer heating pipe. And, first heating pipe 4 and second heating pipe 5 are fixed on lower locating plate 2 through heating pipe support 8, and the upper surface of lower locating plate 2 is formed with stretching muscle 21, and stretching muscle 21 is used for withstanding first heating pipe 4 and second heating pipe 5, like this, can guarantee that the heating pipe is as far as possible level and smooth under the mounted state, also can make heating pipe and 1 bottom surface of inner bag closely laminate. In addition, the first heating pipe 4 and the second heating pipe 5 extend backwards out of the lower positioning plate 2 and are fixed on the liner rear cover 13.

The graphite sheet 6 is tightly adhered to the outer wall surface of the inner concave part 11, specifically, the graphite sheet 6 can be adhered by a double-sided adhesive tape, and the first heating pipe 4 compresses the graphite sheet 6 and is in interference fit with the graphite sheet. Thus, the heat generated by the first heating pipe 4 is more uniformly conducted to the surface of the inner container 1.

In addition, the diameters of the two heating pipes can be properly increased or the heating length of the heating pipes can be lengthened, so that the thermal density of the heating pipes and the temperature of the surface of the heating pipes can be reduced, and the temperature rise of the cabinet at the bottom can be effectively reduced. Of course, half power control can also be used to reduce the cabinet temperature rise.

Under the function mode of steaming, the condensate water at the bottom of the inner container 1 is collected in the inner concave part 11, namely the middle rectangular area, at the moment, the first heating pipe 4 is started to work, the generated heat is uniformly conducted to the condensate water area of the inner container through the graphite sheet 6, and then the condensate water is evaporated efficiently. In the baking function mode, the first heating pipe 4 and the second heating pipe 5 are opened, and can be opened simultaneously or alternatively, so that the heating continuity is ensured.
