The invention discloses a cavity bottom structure of a cooking cavity of a microwave oven, comprising a microwave lead hole, an air vent and a strip-shaped bracket, wherein the microwave lead hole and the air vent are positioned on the side wall of the cooking cavity, and the strip-shaped bracket is arranged on the bottom surface of the cooking cavity and is used for supporting foods; the size of the strip-shaped bracket conforms to the flat surface of the bottom surface of the cooking cavity; the strip-shaped bracket comprises bracket frames and a plurality of support strips fixedly connected on the bracket frames at equal intervals; chutes are arranged at the two side edges of the inner bottom part of the cooking cavity; and the strip-shaped bracket is fixedly arranged on the bottom surface of the cooking cavity by slidably embedding the frames at the two side edges into the chutes. The invention has simple structure, can support and raise the foods only by arranging the strip-shaped bracket on the bottom surface of the cooking cavity of the microwave oven, wherein the size of the strip-shaped bracket is the same as that of the bottom surface; and the bracket has quite small area, fundamentally does not absorb heat, and has good heating effect and heating uniformity for the foods, thus generally improving the heating effect of the microwave oven.
Description
Technical field
The present invention relates to a kind of micro-wave oven.Particularly relate to and a kind ofly can reduce microwave loss, improve the cavity bottom structure of cooking cavity of microwave oven of the efficiency of heating surface of micro-wave oven.
Background technology
In general, micro-wave oven be food is put into and is sealed after, connect power supply to the magnetron that can produce high frequency waves, and with consequent microwave irradiation to food, make the molecule that constitutes the culinary art thing 1 internal vibration in second 2,400,000,000 5 thousand ten thousand times, the cookware that utilizes the frictional heat that produced that food is cooked whereby.
In addition, micro-wave oven is controlled temperature easily, because each position of food can generate heat simultaneously and can evenly cook the food with all size and shape, and have the cooking time of saving and multiple advantage such as easy and simple to handle, so be widely used in general family.
Usually, micro-wave oven has the outward appearance of general lineal hexahedral shape, by the external shell that forms described micro-wave oven outward appearance with can shield the integrant outward appearance of door of face before the described external shell selectively.
And, the top and side of described external shell and following integrally formed, and the back also can be formed by rear board.
In addition, in the inside of described micro-wave oven, be formed with the cavity of the lineal hexahedral shape of the front openings that can put into food for cooking food, after the container of food is equipped with in the placement of the inside of described cavity, microwave irradiation to food, is cooked food with this.
In the inside bottom surface of described cavity, have the pallet of the disc-shape that can support the container that food is housed, described pallet links with the motor that produces revolving force and rotates, and evenly cooks the food that is positioned over described inside cavity thus.
For the microwave in the cavity can be shone on the food equably, the top in cavity also is provided with the agitation fan that is used to stir microwave usually.The type of drive of described agitation fan generally has two kinds: a kind of is rotation by the motor-driven agitation fan, but this type of drive need be provided with motor specially, and cost is higher, and difficulty is installed.Another kind is that the wind that is produced by micro-wave oven itself drives, and the agitation fan structure that adopts this type of drive is to be made of the fan tray that is positioned at the bottom, the flabellum that is integrally formed in the flow-guiding structure on fan tray top and is installed in flow-guiding structure.
Particularly for the micro-wave oven of existing FNR type, as shown in Figure 1, the bottom surface of cooking cavity 1 is provided with the big porcelain dish 3 that can cover the bottom surface, waveguide 4 is arranged at the side of micro-wave oven, when microwave enters the inside of cooking cavity 1 from the side, be to stir, come food is heated by the fan that is arranged in the cavity.Because the microwave guide frame in the cooking cavity 1 is oversize, microwave loss in the process of propagating is serious, and the surface area of porcelain dish 3 is excessive, the absorption microwave is more, directly influenced the heat absorption of heated food, thereby caused the micro-wave oven efficiency of heating surface low, energy dissipation is many.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of propagation path that can shorten microwave, the cavity bottom structure of the cooking cavity of microwave oven of the raising micro-wave oven efficiency of heating surface.
The technical solution adopted in the present invention is: the cavity bottom structure of cooking cavity of microwave oven, include the microwave entrance hole and the steam vent that are positioned on the cooking cavity sidewall, and the bottom surface of cooking cavity is provided with the strip-shaped bracket that is used for support food.
The size of described strip-shaped bracket conforms to the plane of cooking cavity bottom surface.
Described strip-shaped bracket includes rack frame, and equally spaced many lattice framings that are fixedly connected on the rack frame.
The dual-side of described cooking cavity inner bottom part is provided with chute, the be embedded in bottom surface that chute in be fixedly mounted on cooking cavity of described strip-shaped bracket by the frame of dual-side is slided.
The cavity bottom structure of cooking cavity of microwave oven of the present invention, simple in structure, only by the support of a list structure identical with its bottom surface size is set on the bottom surface of cooking cavity of microwave oven, promptly can support food, can be built on stilts food, and the area of support own controls to very for a short time, do not absorb heat substantially, to food add thermal effect and heating uniformity has good effect, improve the thermal effect that adds of micro-wave oven generally.

The specific embodiment
Below, describe the cavity bottom structure of cooking cavity of microwave oven of the present invention in conjunction with the accompanying drawings and embodiments in detail.
As shown in Figure 2, the cavity bottom structure of cooking cavity of microwave oven of the present invention includes the microwave entrance hole and the steam vent 6 that are positioned on cooking cavity 1 sidewall, and the bottom surface of cooking cavity 1 is provided with the strip-shaped bracket 7 that is used for support food.
The size of described strip-shaped bracket 7 conforms to the plane of cooking cavity 1 bottom surface, and promptly the size of the size of the face profile of strip-shaped bracket 7 and shape and cooking cavity 1 bottom surface and profile phase are together.
As Fig. 2, shown in Figure 3, the dual-side of described cooking cavity 1 inner bottom part is provided with chute 10, the be embedded in bottom surfaces that chute 10 in are fixedly mounted on cooking cavity 1 of described strip-shaped bracket 7 by the frame of dual-side is slided.
As shown in Figure 4, described strip-shaped bracket 7 includes rack frame 8, and the equally spaced many lattice framings 9 that are fixedly connected on the rack frame 8.The concrete making be, described rack frame 8 and lattice framing 9 adopt steel wires to make, and the mode by welding will many lattice framings 9 equally spaced be fixedly welded on the rack frame 8 after, adopt the surface to spray again.
Strip-shaped bracket 7 of the present invention can be built on stilts food, and strip-shaped bracket 7 itself do not absorb heat substantially, to food add thermal effect and heating uniformity has good effect; And the area of forming the rack frame 8 of strip-shaped bracket 7 and Duo Gen lattice framing 9 itself is very little, so heat absorption is few, has improved the thermal effect that adds of micro-wave oven.
