Technical field

The utility model relates to a kind of household electrical appliance, the baking box of the heat insulation wind deflector of particularly a kind of tool.

Background technology

Existing baking box, the baking box surface temperature after use is too high and scald the user, and generally the space length with its shell and cavity designs greatlyyer, but also needs to use multilayer insulation material, and it is heat insulation that oven door employing triplex glass carries out the space; Though this design can reduce the baking box surface temperature, increased the baking box volume, make the Roasting oven structure clumsiness, consumptive material is more, and assembly cost and packing cost all can correspondingly increase.

Therefore need a kind of baking box, it not only can reduce the baking box surface temperature effectively with guarantee consumer health safety, and can optimize product structure, and reduces a series of costs.As Chinese patent application CN200920052027.X, name is called " a kind of electric oven of good heat dissipation effect ", its heat dissipation channel inside and outside the baking box top is provided with a connection baking box, to reduce the baking box head temperature, but has following deficiency: though 1. the heat dissipation channel bottom surface is a top thermal insulation board, but thermal insulation board only is a simple plane, and the cold wind utilization rate is not high, and wind effect is limited; 2. only disclosed and how to have reduced the baking box head temperature, do not disclosed the temperature that how to reduce the baking box integral surface, as the surface temperature of oven front and sidepiece.

The utility model content

The utility model provides the baking box of the heat insulation wind deflector of a kind of tool, and it is too high that it has solved the baking box hull-skin temperature in the background technology, and the unconspicuous shortcoming of radiating effect.

The technical scheme that its technical problem that solves the utility model adopts is:

The baking box of the heat insulation wind deflector of a kind of tool, it comprises a shell, and an oven door, wherein:

Offer a plurality of inside and outside through holes that run through on the described shell, an air-guiding aisle is located in the described shell, and a fan is located between the inlet of described through hole and described air-guiding aisle;

Described oven door comprises a glass sandwich, is an inner chamber between the described glass sandwich, and described inner chamber has the wind outlet that an air intake place and that is positioned at the oven door top is positioned at the oven door bottom, and described air-guiding aisle is connected the air intake place;

It also comprises a heat insulation wind deflector, and described heat insulation wind deflector is the bottom surface of described air-guiding aisle and the end face that is positioned at described shell below, and is provided with an air inlet and a plurality of air outlet, and described air outlet is connected described air intake place.

In one preferred embodiment, described heat insulation wind deflector comprises the parting bead that a plurality of are provided with at interval, forms an air channel between per two adjacent parting beads, and described air channel is communicated with described air inlet and has independently described air outlet.

In one preferred embodiment, its shell both sides also are respectively equipped with a thermal insulation layer.

In one preferred embodiment, described parting bead is the segmental arc of metal material.

The baking box of the heat insulation wind deflector of tool of the present utility model is compared with the baking box of background technology, has the following advantages:

1. a heat insulation wind deflector is located at the baking box top, which is provided with a plurality of air channels, and therefore the cold wind that fan can be sucked in is divided into a plurality of zones, has improved the utilization rate of cold wind, compares with the single plane structure of common heat insulation wind deflector, and the wind-guiding effect of heat insulation is better;

2. baking box is provided with an air-guiding aisle, and cold wind enters from air-guiding aisle, by entering behind the heat insulation wind deflector in the glass sandwich of oven door, discharges from oven front at last, can reduce the temperature on oven front surface effectively;

3. the baking box both sides also respectively are provided with a thermal insulation layer, so the top of baking box and anterior when realizing cooling, can also effectively reduce the temperature of baking box both sides, thereby reduce the temperature of baking box integral surface;

4. the air channel on the heat insulation wind deflector is formed by per two adjacent parting beads, and parting bead is the segmental arc of metal material, reasonable in design, and manufacturing process is simple;

5. the space length of shell and cavity is reasonable in design, need not multilayer insulation material, also need not to adopt compound glass as oven door, thus baking box take up room little, outward appearance dexterity, the corresponding reduction of manufacturing cost and packing cost.
