During operation, steam exhausted from the upper inner container 2 enters the upper air guide assembly 6 from the upper air inlet 62 and is finally exhausted from the upper air outlet 63, and steam exhausted from the lower inner container 3 enters the lower air guide assembly 7 from the lower air inlet 72 and is finally exhausted from the lower air outlet 73.

A left side plate air inlet 111 communicated with the middle heat dissipation area is formed in the left side plate 11 of the machine shell 1, a right side plate air inlet 121 communicated with the middle heat dissipation area is formed in the right side plate 12 of the machine shell 1, and a rear side plate air inlet 131 communicated with the middle heat dissipation area is formed in the rear side plate 13 of the machine shell 1. The left side plate air inlet 111 and the right side plate air inlet 121 are used as cold air inlets, and when the air conditioner works, cold air outside the machine shell 1 enters the interior of the machine shell 1 through the cold air inlets and further enters the upper air guide assembly 6 and the lower air guide assembly 7, so that the heat dissipation effect is improved.

In addition, the steam generator assembly 14 is installed at the rear side of the upper inner container 2, heat dissipation holes 132 are formed in the rear side plate 13 at positions corresponding to the steam generator assembly 14, and the heat dissipation of the steam generator can be enhanced through the heat dissipation holes 132.

After the exhaust structure is adopted, as shown by an arrow in the steam channel 78, steam or hot gas firstly moves horizontally and then moves obliquely upwards along the mounting plate 74, and after the steam or hot gas moves in an accelerated manner, the steam or hot gas collects at the part 751 of the obliquely downwards inclined section of the air deflector 75 and finally is obliquely downwards discharged to the atmosphere environment because the cross sectional area of the steam channel 78 is gradually reduced, so that a large amount of steam cannot be condensed on the surface of the upper door body 4, and a small amount of condensed water generated at the lower exhaust port 73 of the lower air guide assembly 7 finally flows into the upper water receiving tank 8 and cannot drop onto the lower door body 5.

As shown in fig. 10, a boss 100 is protruded downwardly from the bottom of the base plate 10. Because the front end of the bottom plate 10 is a high temperature region, and the heat conduction of metal is higher than that of plastic, in this embodiment, two bosses 100 at the front end of the bottom plate 10 are plastic furnace feet resistant to a certain temperature, and three bosses 100 at the rear end of the bottom plate 10 are integrally formed with the bottom plate 10. After the boss 100 is arranged, a certain gap can be ensured between the base plate 10 and the cabinet to form an air layer, so that the temperature rise of the cabinet at the bottom of the whole machine is reduced.

The double-inner-container cooking appliance is an all-in-one steaming and baking machine, wherein the upper inner container 2 is a steaming function cavity, the lower inner container 3 is a steaming and baking function cavity, and a steaming function, a baking function and a steaming and baking combined function can be realized.

The complete machine is at the culinary art in-process, especially roast functional mode, and inside can produce a large amount of heats, and the heat that gives off mainly divide into three regions: an upper heat dissipation area, a middle heat dissipation area and a lower heat dissipation area. The heat of the upper heat dissipation area is mainly the heat dissipated by the upper inner container 2, the heat of the middle heat dissipation area mainly comprises the heat dissipated by the upper inner container 2 and the lower inner container 3 and the heat dissipated by the steam generator assembly 14, and the heat of the lower heat dissipation area is mainly the heat dissipated by the heating pipe 18 and the lower inner container 3.

The working principle of the heat dissipation structure of the embodiment is as follows: when the upper air guide assembly 6 works, a certain negative pressure can be formed in an upper heat dissipation area inside the whole machine, outside cold air is sucked into an upper area inside the whole machine through the left side plate air inlet 111 and the right side plate air inlet 121, is mixed with heat dissipated from the upper heat dissipation area, then is collected at an upper air inlet 62 of the upper air guide assembly 6, and is finally discharged to the atmospheric environment through the upper air outlet 63. When the lower air guide assembly 7 works, a certain negative pressure is formed in the area near the lower air inlet 72, and cold air outside the whole machine enters the inside of the whole machine through the left side plate air inlet 111, the right side plate air inlet 121 and the rear side plate air inlet 131, is mixed with heat in the middle heat dissipation area, and is finally discharged to the atmospheric environment through the lower air outlet 73. Moreover, after the upper heat dissipation area, the middle heat dissipation area and the lower heat dissipation area are communicated through the upper air guide port 61 of the upper air guide assembly 6 and the lower air guide port 71 of the lower air guide assembly 7, the heat of the upper heat dissipation area and the heat of the middle heat dissipation area can be timely discharged, and the heat of the lower heat dissipation area is timely discharged under the negative pressure effect of the upper air guide assembly 6. In addition, the lower air guide assembly 7 can effectively isolate the upper inner container 2 and the lower inner container 3, and can effectively avoid the mutual negative influence of heat emitted by the upper inner container 2 and the lower inner container 3, so that the heat dissipation efficiency is improved.
