Specific embodiment

In order to be more clearly understood that the above objects, features, and advantages of the utility model, with reference to the accompanying drawing and have The utility model is further described in detail in body embodiment.It should be noted that in the absence of conflict, this Shen The feature in embodiment and embodiment please can be combined with each other.

Many details are explained in the following description in order to fully understand the utility model, still, this is practical Novel to be implemented using other than the one described here other modes, therefore, the protection scope of the utility model is simultaneously It is not limited by the specific embodiments disclosed below.

Fig. 1 is the schematic diagram of heating device 100 involved in the utility model embodiment.Fig. 2 is 50 open shape of door body Perspective view under state.As shown in Figures 1 and 2, heating device 100 mainly has pedestal 10, inside can be formed for magnetron, The electrical parts such as frequency converter peace holds electric apparatus room (not shown)；Cavity 20 is set to pedestal 10, and inside is formed with puts for food The heating chamber 34 set, the side of heating chamber 34 are formed as the opening passed in and out for food；Door body 50 is formed on cavity 20, is used In the opening for closing or opening heating chamber 34；Upper cover 70 is covered on cavity 20, and inside can be formed for fan, voice control The upper electric apparatus room (not shown) of the electrical parts such as molding block installation.

Fig. 3 is cavity 20 and its decomposition diagram of association structure involved in the utility model embodiment.Such as Fig. 3 institute Show, cavity 20 specifically includes that the bottom wall 21, roof 22 and rear wall 23 for surrounding heating chamber 34；It is overlapped with rear wall 23 and separates and set Rear bearing sheet 32 setting, being used to support the components such as roof 22 and the rear side outer cover 33 for being covered on 32 outside of rear bearing sheet.It is right It can should be the pedestal 10 of the shapes such as round, similar round or round rectangle in above-mentioned pedestal 10, cavity 20 can be cylindrical, class cylinder Shape or cross section are the shapes such as the cylinder of round rectangle, are illustrated so that cavity 20 is cylinder as an example in the present embodiment, circle Cylindricality is relative to other shapes, in the case where constituting the identical situation of material utilization amount used in cavity 20, the volume of circular cylindrical cavity 20 It is bigger, i.e., heating device can accommodate food materials space it is bigger.

In the present embodiment, bottom wall 21 is in the form of a circular plate, and its center portion it is recessed to 10 side of pedestal and formed for stirring The stir chamber 24 of piece installation (not shown) and movement.Stir chamber 24 is separated by stir chamber cover board 25 with respect to heating chamber 34.Cover board 25 are formed by the material of transparent microwave.Rear wall 23 is arranged in the arc of substantially semicircle along the periphery of bottom wall 21, and roof 22 is same Sample is circular plate, and periphery is connect with rear wall 23, and bottom wall 21, roof 22 and rear wall 23 are formed as front side (user's operation as a result, The side faced when heating device 100) then the closed heating chamber 34 in side, the opening can be closed or be beaten by door body 50 opening It opens.

It is micro- even if door body 50 encloses the opening of heating chamber 34 for the heating device 100 with microwave heating function Wave may still be come out by the gap leakage between door body 50 and cavity 20.For this purpose, in the present embodiment, in the left and right of rear wall 23 two A edge is vertically arranged left side chokes tooth 26 and right side chokes tooth 27 respectively, is arranged above the open side periphery of roof 22 big Semiorbicular upside chokes tooth 28 is caused, substantially semiorbicular downside chokes tooth 29 is set below the open side periphery of bottom wall 21.

Fig. 4 is the decomposition diagram of door body 50 involved in the utility model embodiment and its association structure.Such as Fig. 4 institute Show, door body 50, which specifically includes that, is shaped generally as semicylindrical outer perspective layer 51；Shape be adapted to the outer perspective layer 51, same As substantially semicylindrical interior perspective layer 52；Be configured at it is between outer perspective layer 51 and interior perspective layer 52, be similarly formed as it is big Semicylindrical metal mesh aperture layer 53 is caused, forms numerous through-holes on surface for preventing under microwave heating function microwave by heating Chamber 34 is transmitted by outer perspective layer 51 and interior perspective layer 52, constitutes door with both outer perspective layer 51, interior perspective layer 52 Face；It is shaped generally as circular lower movable guide rail 54, is used for from the fixed above-mentioned outer perspective layer 51 in downside, interior perspective layer 52 And the shop front that metal mesh aperture layer 53 is formed；Guide rail 55 is fixed in downside, is formed as the ring-type being adapted to lower movable guide rail 54, uses In from downside and/or outside-supporting lower movable guide rail 54, i.e., the fixed guide rail in downside supports lower movable guide rail from downside, or under The fixed guide rail in side from the fixed guide rail of outside-supporting lower movable guide rail or downside from downside and outside-supporting lower movable guide rail, And lower movable guide rail 54 can the fixed sliding of guide rail 55 of opposite lower or the rolling of multiple rollers 56 by being arranged between the two；Shape As substantially circular upper movable guide rail 57, it is used for from the fixed above-mentioned shop front in upside；Guide rail 58 is fixed in upside, is formed For the ring-type being adapted to upper movable guide rail 57, it is used for from upside and/or outside-supporting upper movable guide rail 57, i.e. upside is fixed Guide rail supports the fixed guide rail of upper movable guide rail or upside to lead from outside-supporting upper movable guide rail or upside fixation from upside Rail is from upside and outside-supporting upper movable guide rail, and upper movable guide rail 57 the fixed sliding of guide rail 58 of opposite upper or can pass through The multiple rollers being arranged between the two are (not shown) to be rolled.It should be noted that in the figure due to metal mesh aperture layer 53 and outer It is fitted closely depending on layer 51, interior perspective layer 52, in figure and its not specifically illustrated structure.

In addition, Fig. 5, which shows heating device, removes the structural schematic diagram after upper cover.Fig. 6 shows the exploded pictorial of Fig. 5 Figure.As shown in Figure 5 and Figure 6, heating device further includes top support plate 72, and top support plate 72 is set to cavity 20.Top branch Fagging 72 is for being fixedly connected with the fixed guide rail 58 of rear bearing sheet 32 and upside, at this time since cavity is cylindrical, using arc Rear bearing sheet can increase the load-bearing capacity of cavity, so that top support plate provides the component being provided thereon more stable support. When top support plate 72 is fixedly connected with the fixed guide rail 58 in upside, door body 50 is tightly engaged into top support plate 72, is reduced and is added Hot cooking device internal heat is scattered and disappeared.It is understood that the fixed guide rail 58 of top support plate 72 and rear bearing sheet 32 and upside It connects simultaneously, forming top support plate 72 and rear bearing sheet 32, rear side is continuous, and front side has the formation of heating chamber 34 of opening One frame realizes the folding of opening by the opening and closing of door body 50, so as to increase the structural strength of heating device entirety, Keep each structure connection of heating device more firm.The structure of heating device using the above structure is simple, assembling parts It is few, it simplifies assembling procedure, promote packaging efficiency.

Fig. 7 and Fig. 8 respectively illustrates the partial enlarged view in Fig. 5 at A and B.Fig. 9, Figure 10 and Figure 11 respectively illustrate Fig. 6 Partial enlarged view at middle C, D and E.
