Description

A kind of Steam roaster with hot air convection

Technical field

Steam roaster is the utility model is related to, especially a kind of Steam roaster with hot air convection.

Background technology

Steam roaster is provided simultaneously with that the function of steam box and baking box is extensively concerned, and existing Steam roaster inner bag is generally set with it There is levels heating tube, to realize the function of baking box；Steam raising plant is added simultaneously, by the way that the heating and continuous generation of water is high Warm steam is simultaneously communicated to inner bag, so as to which the food in inner bag is heated by high-temperature steam, realizes the function of steam box.

But in baking or steam cooking, due to the temperature drift at electro-heat equipment, the temperature away from electro-heat equipment Relatively low, i.e. the thermal field of inner bag is uneven, causes food uneven heating, and heat transference efficiency is low, does not reach preferable heating effect.

The content of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of Steam roaster with hot air convection.

Technical scheme is used by the utility model solves its technical problem：

A kind of Steam roaster with hot air convection, including casing, the casing is interior to be provided with inner bag and heater I； The steam raising plant for accessing the inner bag is provided between the inner bag and casing, is separated to form inside the inner bag by dividing plate Interconnected convection cavity and cooking chamber, the convection cavity are provided with all edges for the central ventilated mouth I sums for leading to the cooking chamber Ventilating opening II, be provided with the convection cavity positioned at described ventilating opening I, II between and can intermittently forward and reverse rotation wheel rotor with And the steam in convection cavity is carried out to the heating device II of reheating.

The convection cavity is in flat, and it is axially arranged that the wheel rotor corresponds to the ventilating opening I, the heating device II Around being located at outside the wheel rotor.

The dividing plate is fixed on the inner bag rear wall, its middle part arch upward cooperatively formed with the side wall of inner it is described Convection cavity.

The size of the ventilating opening I and the wheel rotor diameter are similar.

Described ventilating opening I, II are made up of the hollow out hole position on the dividing plate.

The steam raising plant is accessed in the convection cavity.

The beneficial effects of the utility model are：By being provided with built-in wheel rotor and heating dress in the inner bag of Steam roaster Put II convection cavity, the high-temperature steam in inner bag or air circulating-heating, flowing is formed hot blast, and wheel rotor can between Have a rest positive and reverse steering, hot blast sphere of action under positive and negative alternate rotation is wider, and thermal field is more uniformly distributed, and the heating effect of food is more preferable.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is structural representation of the present utility model；

Fig. 2 is internal structure schematic diagram of the present utility model.

Embodiment

Referring to figs. 1 to Fig. 2, a kind of Steam roaster with hot air convection, including casing 1, be provided with casing 1 inner bag 2 with And heater 3, while the steam raising plant 4 of access inner bag 1 is provided between inner bag 2 and casing 1, filled by upper and lower heating The part or all of calling of 3 and steam raising plant 4 is put, realizes baking or steam cooking function.

Wherein, interconnected convection cavity 6 and cooking chamber are separated to form inside inner bag 2 by dividing plate 5, is set on convection cavity 6 There are the central ventilated mouth I 51 for leading to cooking chamber and week along ventilating opening II52, convection cavity 6 is interior to be provided between ventilating opening I, II Wheel rotor 7 and can to flow through convection cavity 6 steam carry out reheating heating device II 8, it is possible to increase steam temperature Degree, realization quickly cook.

Simultaneously in order to avoid wheel rotor 7 rotates in a one way-direction for a long time, some locus are made to form dead angle, that is, Some places do not have air flow, and by being electrically connected or programming motor can be made to occur within every five minutes once to turn to changes Become, so as to realize the interval positive and negative rotation of wheel rotor 7, i.e. hot blast forms turbulent flow under positive and negative alternate rotation, so that hot blast Sphere of action is wider, and thermal field is more uniformly distributed, and the heating effect of food is more preferable.

When being rotated forward such as wheel rotor 7, the ventilating opening I 51 of steam or air through centre flows into convection cavity 6, through reheating After device 8 heats again, then flow out from the ventilating opening II 52 on all edges, the high-temperature steam or air after heating from the periphery of inner bag 2 to Center flowing；And during the reversion of wheel rotor 7, the flow direction of hot blast is still identical, and wheel rotor 7 is formed at ventilating opening I 51 Negative pressure, make to be internally formed turbulent flow, hot blast can flow to some dead angles that rotating forward process can not touch, and thermal field is more uniformly distributed.

In order to expand the space of cooking chamber as much as possible, convection cavity 6 is arranged to flat, and wheel rotor 7 then corresponds to ventilation Mouthful axially arranged deflectings for realizing hot blast of I51, and heating device II 8 is around being located at outside the wheel rotor 7, through the band of wheel rotor 7 Dynamic steam or air can obtain reheating, improve steam heating-up temperature.

Further, dividing plate 5 is fixed on the rear wall of inner bag 2, and its middle part is arched upward cooperatively forms convection current with the side wall of inner bag 2 Chamber 6, simple in construction, assembling simplicity.

Wherein, the sizes of ventilating opening I 51 and the diameter of wheel rotor 7 are similar, hot blast operating efficiency highest.Such as ventilating opening I 51 When size relative rotation impeller 7 is larger, due to getting too close to second heating apparatus 8, some vapor or air can be caused without two Secondary heating is altered into so as to reduce the overall efficiency of heating surface from ventilating opening I51 edges；And ventilating opening I 51 size is relative If wheel rotor 7 is small, air intake efficiency can be reduced again.

Ventilating opening I, II are made up of the hollow out hole position on dividing plate 5, and food or hand hold when avoiding single ventilation hole position excessive Heating tube of the easy false touch in it, it is safer, while will not substantially reduce convection effects.

In addition, can access to steam raising plant 4 in convection cavity 6, the high-temperature steam of ejection by reheating with filling Put in mixing heel row to the inner bag 2 of the high-temperature vapour after 8 heating, accelerate hot air convection speed.

Hot air convection structure of the present utility model, can make inner bag 2 produce the hot air circulation of inside, and food is heated more equal Even, the efficiency of heating surface is high, and food mouthfeel is more preferable.
