Abstract
Description
Technical Field
[0001] The utility model relates to a steaming and baking all-in-one machine, belonging to the field of kitchen appliances. Background Art
[0002] When using the steam oven for cooking, the steam-bake combination machine discharges excess steam to the outside through the exhaust holes. After cooking, a large amount of steam will still remain in the steam oven cavity. The moment the user opens the door, a large amount of steam or high-temperature smoke will diffuse from the cavity to the outside and directly spray the user, causing a bad user experience. Summary of the invention
[0003] The utility model aims to provide a stove-steaming and baking all-in-one machine with a cooking device, aiming to solve the technical problem of direct spraying of steam or high-temperature smoke to users and meet the needs of users.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows: a steam-bake all-in-one machine, the inner pot is provided with an air outlet, and the inner pot is also provided with an air inlet, and the air inlet is connected to a centrifugal fan through a pipeline. When the steaming / bake mode ends, the centrifugal fan is turned on to fill air into the inner pot, increase the pressure in the cavity, thereby accelerating the discharge of steam or high-temperature smoke, and when the user opens the door, the steam or high-temperature smoke from the inner pot is prevented from directly spraying onto the user's face, thereby improving the user's experience.
[0005] Furthermore, the pipeline is provided with an air intake valve sheet for one-way flow from the centrifugal fan to the inner tank, which plays a role in preventing airflow and heat from gushing out to the impeller of the centrifugal fan.
[0006] Furthermore, the pipeline includes an air inlet elbow, a sealing gasket, an air inlet pipe welding plate, and an air inlet pipe; the air inlet pipe welding plate and the air inlet pipe seal are welded into one body and sealed and fixed to the outer surface of the inner tank through the sealing gasket; the air inlet elbow is tightly attached to the sealing gasket and sealed and fixed to the air inlet pipe welding plate.
[0007] Furthermore, the air intake valve sheet is hung on a small cylinder at the upper end of the air outlet side of the air intake elbow, and the air intake valve sheet is attached to the surface of the air intake elbow by its own weight or the positive pressure of the inner tank.
[0008] Furthermore, the centrifugal fan is fixedly mounted on a centrifugal fan bracket.
[0009] Compared with the prior art, the beneficial effect of the utility model is that the air intake valve plate is stationary without external force, but when the centrifugal fan is electrically working, the fan blade rotates at high speed, generating a strong airflow, and the air intake valve plate is changed from its stationary state through the air intake elbow, and the air intake valve plate is deformed, that is, the circular hole of the air intake elbow is opened, and the airflow of the centrifugal fan rushes into the inner pot, and in the shortest time, the heat or water vapor in the sealed inner pot 9 of the cooking food is discharged to the outside of the inner pot, without waiting for the heat or water vapor to naturally rush out after the door is opened. The utility model is easy to manufacture and low in cost, and effectively solves the pain points of consumers using steam ovens, ovens, and steam boxes. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0015] like Figure 1 As shown, a steam-bake combination machine has an inner pot provided with an air outlet 11 and an air inlet 7. The air inlet 7 is arranged on the side of the cavity, and the air outlet 11 is arranged on the upper part of the cavity steam oven. The air inlet 7 is connected to the centrifugal fan 2 through a pipe. The centrifugal fan 2 is fixed on the outside of the product inner pot 9. When needed, the fan starts to rotate to infuse wind pressure into the inner pot 9. The air pressure in the inner pot 9 increases suddenly. In this state, heat and steam are discharged from the air outlet 11 faster. After the centrifugal fan 2 is powered on and works for a period of time, the inner pot 9 is cooled down. At this time, the consumer opens the oven door, and the pain point of consumers who previously had heat waves and a large amount of water vapor gushing out when opening the door is overcome. As Figure 4 As shown, the air inlet 7 is a plurality of small round holes with a diameter of about 5 mm or less opened on the side of the inner tank 9, and the round holes are for air flow to pass through. Figure 1 To give a comprehensive explanation, as shown in the figure, first weld 4 welding screws 8 on the outside of the inner liner 9. The air inlet pipe 6 presses the sealing gasket 4 and is fixed on the welding screws 8 of the inner liner 9 and fixed with 4 nuts. The air inlet pipe 6 and the air inlet pipe welding piece 5 can be seamlessly welded and fixed into a whole, see Figure 3. The air inlet pipe welding piece 5 is fixedly connected to the air inlet elbow 3, and there is a sealing gasket 4 between them for auxiliary sealing. The air inlet elbow 3 is a high-temperature resistant plastic part. It has a semi-circular corner to better guide the air into the inner tank 9. The centrifugal fan 2 can minimize the wind resistance when entering the inner tank 9 through the air inlet elbow 3. The centrifugal fan 2 is installed on the centrifugal fan bracket 1. The two mounting holes of the centrifugal fan 2 are fastened to the bracket. The air inlet of the centrifugal fan 2 is the air in the environment, and the outlet is nested in the air inlet elbow 3. The centrifugal fan 2 is nested in the air inlet elbow 3. The two small cylinders on the air inlet elbow 3 are hung with an air inlet valve plate 12 made of silicone parts. The air inlet valve plate 12 relies on the positive pressure of the inner tank under its own weight to fit on the surface of the air inlet elbow 3, which prevents the airflow and heat of the inner tank 9 from flowing out to the impeller of the centrifugal fan 2. The air intake valve plate 12 is stationary without external force, but when the centrifugal fan 2 is electrically operated, the fan blades rotate at high speed, generating a strong airflow, which changes the stationary state of the air intake valve plate 12 through the air intake elbow 3, causing the air intake valve plate 12 to deform, such as Figure 2 As shown, the circular hole of the air inlet elbow 3 is opened, and the airflow of the centrifugal fan 2 flows into the inner pot 9. The air inlet 7 is closed during the normal working time of cooking food, and the heat and steam generated by the electric heating tube in the product will not leak; the air outlet 11 is open, which can stably discharge the excess heat and steam, stabilize the air pressure in the inner pot 9, and ensure that the pressure in the inner pot 9 is balanced and stable.
