[0026] In the process of baking food, it is necessary to add materials many times, such as brushing sugar water on the surface of food, sprinkling salt on the surface of food, etc. The traditional steam oven needs to open the door to take out the food for the above operation, which causes the food to cool down in the middle and affects the taste. In addition, the operation is troublesome and there is a risk of scalding. The inner glass plate 40 can be opened to close the feeding window of the door 2. When feeding is needed, the size of the slurry outlet pipe 28 is smaller than the size of the feeding window on the door 2. When feeding is needed, slurry is added to the slurry tank 27, and the inner glass plate 40 is pushed inward through the slurry outlet pipe 28, so that the slurry outlet pipe 28 extends into the feeding window of the box door 2. At this time, a channel 1 is formed between the transverse partition of the upper plate 29 and the top wall of the slurry outlet pipe 28, and between the vertical partition of the upper plate 29 and the side wall of the slurry tank 27. The channel 1 balances the air pressure in the high-temperature chamber of the inner tank 5 and the slurry chamber of the slurry tank 27. The slurry pump 31 is operated to extract the slurry in the slurry tank 27 and then spray it into the food surface in the high-temperature chamber through the nozzle 32, so as to replenish the slurry on the food surface. There is no need to take out the food, which can avoid the food cooling down in the middle and affecting the taste. The operation is simple, there is no risk of scalding, and the convenience is improved.

The transverse partition 2 of the upper plate 35 is located in the powder discharge pipe 34. The vertical partition 2 of the upper plate 35 is located in the powder chamber of the powder tank 33. A gap 2 is set between the upper end of the upper plate 35 and the top wall of the powder tank 33. The impeller 36 is rotatably installed in the powder discharge pipe 34. The impeller 36 is located below the transverse partition 2 of the upper plate 35. The impeller 36 is provided with a plurality of blades arranged circumferentially. The upper plate 35 is installed with an air supply pipe 37, and the air supply pipe 37 is connected to the middle part of the impeller 36.

The guide plate 38 is located on the outer side of the impeller 36, and the steering shaft 39 is connected to the rotating shaft of the guide plate 38.

[0028] The size of the powder discharge pipe 34 is smaller than the size of the feeding window on the box door 2. When feeding is needed, powder is added to the powder tank 33, and the inner glass plate 40 is pushed inwardly through the powder discharge pipe 34, so that the powder discharge pipe 34 extends into the feeding window of the box door 2. At this time, a channel 2 is formed between the transverse partition 2 of the upper plate 2 35 and the top wall of the powder discharge pipe 34, and between the vertical partition 2 of the upper plate 2 35 and the side wall of the powder tank 33. Channel 2 balances the air pressure in the high-temperature chamber of the inner tank 5 and the powder chamber of the powder tank 33.

[0029] like Figures 1 to 12As shown, a commercial electric steaming and baking heat preservation and displaying integrated machine of the present invention is used. When the steaming function is required, water is added to the water storage chamber of the water interlayer 6, and the electric control valve 8 is opened to allow the water in the water storage chamber of the water interlayer 6 to be input into the electric control valve 8 through the water pipe 7 and then input into the water tank of the inner pot 5 through the water outlet head 9. The heating tube 3 in the water tank is turned on to heat and evaporate the water, so that the high-temperature steam heats the food in the high-temperature chamber to realize the steaming function. In this process, the opening and closing size of the electric control valve 8 is adjusted to allow the water in the water tank of the inner pot 5 to be heated. The evaporation of water is balanced with the replenishment amount, and the steam in the high-temperature chamber fills the high-temperature chamber. As the steam pressure increases, when the thrust of the steam on the piston 19 is greater than the elastic force of the spring 20, the piston 19 slides outward along the piston cylinder of the pressure relief pipe 18, so that the piston 19 drives the baffle 21 to move, and the outer port of the pressure relief pipe 18 is opened, and the steam or high-temperature air is released to reduce the pressure, thereby realizing high-pressure steaming of the food in the high-temperature chamber; then the residual heat of the steam in the high-temperature chamber heats the inner pot 5 and the water interlayer 6, so that the water in the water storage chamber of the water interlayer 6 is heated. The water is heated, and when the food is cooked, the door 2 is opened to take the food out of the high temperature chamber and put it into the insulation chamber above the insulation partition 4, and the door 2 is closed. At this time, the heat of the high temperature water in the water interlayer 6 keeps the food in the insulation chamber warm; then when the baking function is needed, water is added to the water storage chamber of the water interlayer 6, the electric control valve 8 is closed, and the heating tube 3 in the water tank of the inner pot 5 and the heating tube 3 under the insulation partition 4 are turned on to bake and heat the food in the high temperature chamber. When refilling is needed, the refilling mechanism is pushed inward to open the inner glass plate 40 The food is put into the heat preservation chamber above the heat preservation partition 4, and the door 2 is closed. At this time, the heat of the high-temperature water in the water layer 6 keeps the food in the heat preservation chamber warm. The heated and warmed food can be displayed through the transparent glass on the door 2.

[0030] The main functions achieved by the present invention are: 1.
