The baking utensil of one embodiment of the utility model described in detail below:
As shown in Figures 1 to 7, baking utensil includes shell 12 and front door 22, and food materials hold bucket 18 and are placed in shell 12
It heats in room 14, heats and be equipped with cavity back plate on rear side of the cavity of room 14, be equipped with exhaust vent 142, cavity back plate in the middle part of cavity back plate
Marginal position is equipped with air inlet hole 144, after the intracorporal cold wind of chamber is inhaled into cavity from the exhaust vent 142 in the middle part of cavity back plate when use
The rear side of plate becomes hot-air after heat temperature raising, then blows out from the air inlet hole 144 at cavity back plate edge, heats food materials
The food in bucket 18 is held, realizes and bakes function.As shown in figure 3, the rear side of cavity back plate is equipped with fan component 16 and fever member
Part 20, the effect of fan component 16 are that exhaust vent 142 of the intracorporal cold air of chamber in the middle part of cavity back plate is drawn, and work as cold air
When flowing through heater element 20, cold air is heated as hot-air, then when being blown into heating room 14 from air inlet hole 144, can be to food
The food that material holds in bucket 18 plays the role of heating, and the bottom of heating room 14 is additionally provided with mixing component, can hold to food materials
Food in bucket 18 is stirred;As shown in Fig. 3 to Fig. 7, fan component 16 is by the second impeller 162b, the first impeller 162a, tight
Firmware 166, supporting element 168 and driving motor 164 form, and the first impeller 162a and the second impeller 162b are installed in parallel in driving electricity
The same side of the transmission shaft of machine 164, is equipped with supporting element 168 between the two, and the effect of supporting element 168 is to limit the first impeller 162a
With distance of the second impeller 162b in the transmission axis direction of driving motor 164, play the role of positioning and fastening, two impellers
162 are locked on the transmission shaft of driving motor 164 by fastener 166, and the first impeller 162a is centrifugal flabellum in the present embodiment,
It is the direction for being parallel to transmission shaft that direction is entered the wind when its work, and air-out direction is the direction perpendicular to transmission shaft, when the first impeller
When 162a high-speed rotation, due to its blade shape and rotation direction be it is fixed, the direction of motion easy to form is more regular
Air-flow, the air-flow of this type is easy to make impeller 162 to generate resonance, so that the noise for generating the movement of impeller 162 increases, this
Outside, for the food that food materials are held in bucket 18, when excessively regular air-flow is blown out from air inlet hole 144, food materials hold bucket 18
Interior food is easy to be heated excessively in the stronger position of air-flow, and the position then underheat, therefore heating effect that air-flow is weaker
Fruit is simultaneously uneven, in order at least be partially solved this problem, increases the second impeller 162b, this reality in the front side of the first impeller 162a
Applying the second impeller 162b in example is a kind of axial flow fan leaf, and air inlet direction is the direction for being parallel to transmission shaft, outlet air side when work
It is the direction for being parallel to transmission shaft to also, due to the air inlet direction phase in the air inlet direction and the first impeller 162a of the second impeller 162b
Together, more air quantity can be made to enter heating chamber under same rotating speed, enhances the effect of air inlet, the generation of the second impeller 162b
Air-flow again can with the first impeller 162a generate air-flow mutually disturb, and change the first impeller 162a generate air-flow stream
To generation when generating resonance because of the air-flow of rule so as to avoid the first impeller 162a, reduce the first impeller 162a work
Noise, while disperse the air-flow blown out from air inlet hole 144 more, be more advantageous to and be evenly heated food materials and hold in bucket 18
Food promotes Baking Effect.
In another embodiment, increased second impeller 162b is also possible to the fan with the first impeller 162a same type
Leaf, for example, the second impeller 162b and the first impeller 162a are centrifuge blade, during installation, the second impeller 162b and the first leaf
The certain angle that is staggered between the blade of 162a is taken turns, generating when rotating two impellers 162 is that air-flow mobility status is not quite identical,
Also noise reduction and diffusing air current may be implemented, make to heat effect more evenly.
