Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 3, the dual-inner-container cooking appliance in this embodiment includes a casing 9, and an upper inner container 1 and a lower inner container 2 which are disposed inside the casing 9, where the upper inner container 1 corresponds to an upper door assembly 5, the lower inner container 2 corresponds to a lower door assembly 6, and a gap is formed between the upper door assembly 5 and the lower door assembly 6. The air guide assembly 3 is installed between the upper inner container 1 and the lower inner container 2, the upper inner container 1 is provided with an upper air outlet 11, the lower inner container 2 is provided with a lower air outlet 21, the air guide assembly 3 is provided with an upper air inlet 31, a lower air inlet 32 and an air outlet 33, the upper air outlet 11 is communicated with the upper air inlet 31 through an upper air exhaust pipe (not shown), and the lower air outlet 21 is communicated with the lower air inlet 32 through a lower air exhaust pipe (not shown). During operation, steam exhausted from the upper inner container 1 enters the air guide assembly 3 through the upper air outlet 11 and the upper air inlet 31, and steam exhausted from the lower inner container 2 enters the air guide assembly 3 through the lower air outlet 21 and the lower air inlet 32, and is finally exhausted from the air outlet 33 of the air guide assembly 3.

In this embodiment, the upper air outlet 11 is higher than the upper air inlet 31, so that the condensed water in the air guiding assembly 3 can be prevented from flowing back to the upper inner container 1, and the condensed water generated in the cooking process of the upper inner container 1 is reduced. An air outlet 33 of the air guide assembly 3 is over against a gap between the upper door body assembly 5 and the lower door body assembly 6, and a water receiving groove 4 for receiving condensed water discharged from the air outlet is arranged below the air outlet 33.

As shown in fig. 4 and 5, the air guiding assembly 3 of the present embodiment specifically includes an installation plate 34, an air guiding plate 35, a motor 36, and a fan blade 37. The air deflector 35 comprises a front air deflector 351 and a rear air deflector 352, the front air deflector 351 and the rear air deflector 352 are detachably fixed together in a front-back mode to form the whole air deflector 35, the connecting part is sealed and air-tight, and after the air deflector 35 adopts a detachable structure, the motor can be conveniently detached for maintenance under the condition of failure. The front air deflector 351 and the rear air deflector 352 are arranged above the mounting plate 34, the motor 36 is mounted on the rear air deflector 352, and the fan blades 37 are mounted on the output shaft of the motor 36. The upper air inlet 31 of the air guide assembly 3 is provided on the rear air guide plate 352, the lower air inlet 32 is provided on the mounting plate 34, and the air outlet 33 is formed in the outlet gap between the mounting plate 34 and the front air guide plate 351.

As shown in fig. 6, the air outlet end of the front wind guiding plate 351 has an inclined section 3511 inclined downward, the air outlet end of the mounting plate 34 is sequentially formed with a rear inclined section 341 inclined upward, a middle inclined section 342 inclined downward and a front horizontal section 343 along the air outlet direction, the rear inclined section 341 is disposed behind the upper inclined section 3511, the vertical projection of the upper inclined section 3511 falls on the middle inclined section 342 and the front horizontal section 343, and the inclined angle of the upper inclined section 3511 is the same as that of the middle inclined section 342. After the outlet end of the front air guiding plate 351 and the outlet end of the mounting plate 34 adopt the above special structure, as shown by an arrow in the steam channel 30, steam or hot gas firstly moves horizontally and then moves obliquely upwards along the mounting plate 34, because the cross-sectional area of the steam channel 30 is gradually reduced, after the steam or hot gas moves in an accelerated manner, the steam or hot gas collects at the part of the upward inclined section 3511 of the front air guiding plate 351 obliquely downwards and is finally discharged obliquely downwards to the atmosphere environment, therefore, a large amount of steam cannot be condensed on the surface of the upper door body assembly 5, and a small amount of condensed water generated at the air outlet 33 of the air guiding assembly 3 finally flows into the water receiving groove 4 below the air outlet 33 and cannot drop onto the lower. Usually, the door plant surface of last door body subassembly 5 adopts glass, and control panel 8 installs on last door body subassembly 5, consequently, can effectively avoid steam to condense on last door glass 51 and control panel 8, promotes user experience.

In addition, the double-liner cooking appliance of the embodiment is an integrated steaming and baking machine, wherein the upper liner 1 is a steaming function cavity, and the lower liner 2 is a steaming and baking function cavity, so that a steaming function, a baking function and a steaming and baking combined function can be realized. The steam generator 7 is fixed on the mounting plate 34 of the air guide component 3 and is positioned at the rear of the upper inner container 1, a steam outlet 71 of the steam generator 7 is communicated with steam inlets (not shown) of the upper inner container 1 and the lower inner container 2, and a steam passage between the steam generator 7 and the upper inner container and the lower inner container is of a conventional structure and is not described herein. This air ducting locates air guide component 3 between upper liner 1 and lower inner bag 2, not only can promote the inner bag volume, increases the space of other spare part overall arrangements, and air intake 33 of air guide component 3 is located the middle zone of complete machine moreover, and is closer with the great spare part distance of calorific capacity such as steam generator 7 and lower inner bag 2 to can promote the radiating efficiency.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications or improvements may be made to the present invention without departing from the principle of the present invention, for example, the wind guiding system of the present embodiment is also applicable to a double-liner steam box, which are all considered to be within the protection scope of the present invention.
