Embodiment
In the present invention, in the case where not making opposite explanation, the noun of locality such as " upper and lower, left and right " used typically refers to
All parts mutual alignment for direction shown in the drawings or on vertical, vertical or neutral direction
Relationship description word." inside and outside " refers to that the internal cavities of the parts with internal cavities are " interior ", is outside internal cavities
" outer ".
As shown in Fig. 2 to Fig. 3, the micro-wave oven of a preferred embodiment of the invention, including form heating chamber
The bottom wall 3 of a part, depression forms microwave stirring chamber 30, opening of the microwave stirring chamber 30 with respect to heating chamber to bottom wall 3 downwards
Place, which is embedded with, to be used to close the opening and can penetrate the dividing plate 1 of microwave, and microwave stirring chamber 30 is separated with respect to heating chamber.
The downside of bottom wall 3 is provided with magnetron 4, also, the antenna end 40 of magnetron 4 is from the side wall of microwave stirring chamber 30
The mouth 32 that stretches into opened up is extended in microwave stirring chamber 30.The microwave that antenna end 40 is sent can pass through microwave stirring chamber 30
Import in heating chamber.Stirring sheet 2 is rotatablely equipped with microwave stirring chamber 30, to cause dividing plate 1 to enter the heating of micro-wave oven
The microwave of inner chamber is more uniform.
When using above-mentioned setting, the side wall of microwave stirring chamber 30 doubles as the waveguide coordinated with magnetron 4, equivalent to
Waveguide is integrally machined on bottom wall 3.From assembly technology, it is this be wholely set form can save jointing waveguide pipe with
The process of bottom wall 3；From taking in size, in the existing structure representated by Fig. 1, the teeter chamber on bottom wall will at least meet to stir
Space required for piece rotation, and to there is the installation that must is fulfilled for magnetron and waveguide between the bottom plate of micro-wave oven below bottom wall
Space, the vertical dimension of micro-wave oven are mainly increased by the installation of magnetron.And by using the structure of the present invention, stirring sheet
2 are built in microwave stirring chamber 30 so that the vertical direction spatial that this position of micro-wave oven takes is smaller；Most importantly,
In the performance evaluation of micro-wave oven, a particularly important index is the utilization ratio of microwave, and in order to improve the utilization ratio,
, it is necessary to carry out matching repeatedly during microwave oven is matched somebody with somebody, to cause the position for being used to cure food in heating bore to heat effect
Rate reaches highest.The variable for influenceing the output of matching process has two：The waveguide mouth of microwave and the shape of stirring sheet, prior art
The middle waveguide mouth needed on the plate body of inner chamber adjusts the position of waveguide repeatedly, and adjusts the shape of stirring sheet simultaneously, two
Parameter adjusts simultaneously causes matching process complex.And waveguide is integrally formed on bottom wall 3, microwave stirring chamber 30
Opening then can all be regarded as " waveguide mouth ", fix equivalent to by the position of waveguide mouth and waveguide, needed in matching process
The parameter of adjustment only has the shape of stirring sheet 2, and matching process is simplified.
Bottom wall 3 is preferably made of the metal material with preferable ductility, the one stretching shape of microwave stirring chamber 30
Into on the bottom wall 3, also, bottom wall 3 has from the edge of opening of microwave stirring chamber 30 and stretched out the epitaxy part 31 to be formed,
The downside of the epitaxy part 31 is provided with magnetron 4.As further preferred scheme, the support 41 of magnetron 4 is bonded epitaxy part
31 downside surface is set, to reduce the space of the micro-wave oven shared by the vertical direction magnetron 4 as far as possible.
In above-mentioned preferred embodiment, microwave stirring chamber 30 is machined in a manner of integrally formed on bottom wall 3, and
The microwave stirring chamber 30 also serves as the waveguide of magnetron 4, and therefore, the depth value of microwave stirring chamber 30 is larger, for the ease of
The knockout course of mould during processing, microwave stirring chamber 30 extend from cavity bottom to opening direction flaring.
Magnetron 4 is fixed to by magnetron mounting bracket 5 on the lateral wall of microwave stirring chamber 30.And as one kind
Preferred scheme, microwave stirring chamber 30 are formed as rectangular chamber, and magnetron mounting bracket 5 is fixed on the rectangle of the rectangular chamber
In the less side wall of horizontal direction width of side wall where short side, i.e. rectangular chamber.When microwave stirring chamber 30 is using diagram
Flaring extension form when, the side wall for installing magnetron 4 is the side wall being obliquely installed, in order to ensure the heating of magnetron 4
Efficiency, antenna 40 should be extended in microwave stirring chamber 30 with the orientation of axis horizontal or basic horizontal, therefore, magnetron
Support 5 includes the first mounting bracket 50 and the second mounting bracket 51.First mounting bracket 50 is connected to the lateral wall of microwave stirring chamber 30
Above and vertical installation surface is being formed close to the side of the second mounting bracket 51, the second mounting bracket 51 is being fixed to first mounting bracket 50
On, the support 41 of magnetron 4 is fixed with the second mounting bracket 51.
Electric machine support 7 is installed, for driving the motor 6 that stirring sheet 2 rotates can in the exterior bottom wall of microwave stirring chamber 30
In on the electric machine support 7, the motor shaft of motor 6 prolongs dismantling connection upwards through the centre bore on the bottom wall of microwave stirring chamber 30
Stretch so that the setting height(from bottom) of stirring sheet 2 is higher than the height of the free end of antenna end 40, with before microwave penetrates heating chamber upwards
Stir.
Further, formed with caulking groove, dividing plate 1 stirs in the caulking groove for the upper end of microwave stirring chamber 30
The upper end level of piece 2 is no more than the bottom land height of the caulking groove, so that stirring sheet 2 can freely turn in microwave stirring chamber 30
It is dynamic.
Stirring sheet 2 has circular contour, also, foundation needs in the matching process, formed with matching technique in stirring sheet 2
Hole 20.It should be pointed out that the shape in matching technique hole 20, quantity and its set location in stirring sheet 2 are not fixed, this
A little parameters need according to the adjustment in matching process and carry out adaptability setting.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited thereto.At this
In the range of the technology design of invention, a variety of simple variants, including each particular technique can be carried out to technical scheme
Feature is combined in any suitable manner, and in order to avoid unnecessary repetition, the present invention is to various combinations of possible ways
No longer separately illustrate.But these simple variants and combination should equally be considered as content disclosed in this invention, belong to the present invention
Protection domain.
