It should be noted that the term "steaming and baking box" as used herein refers to a multifunctional food processor with steam function, and any food processing device including a steam function is included in the scope of the present application.

The utility model discloses a cavity 2 of embodiment is the rectangle casing, and concrete structure can include roof 21, flat board 22, front bezel 23 and back plate 24, and flat board 21 is integrated into one piece's U-shaped, and roof 22 attaches and locates flat board 21's U-shaped open-top portion department, and front bezel 23 and back plate 24 cover flat board 21 respectively from the past after. In practical use of the steaming and baking oven 1, the top plate 21, the flat plate 22, the front plate 23 and the rear plate 24 are fixedly connected (preferably riveted) to form a cavity for accommodating an object to be treated, and a door (not shown) of the steaming and baking oven 1 is rotatably connected to the front plate 23. Of course, the chamber 2 is not limited to such a structure, and may contain the object to be processed.

Since the chamber 2 is formed by caulking or other connecting means of a plurality of members of the top plate 21, the flat plate 22, the front plate 23 and the rear plate 24, the inside of the chamber 2 is formed as a relatively closed space after the chamber 2 is closed by a door not shown. After the treated object is heated in the cavity 2 through steam or hot air, a large amount of water vapor can be generated in the cavity 2, the water vapor can be condensed into condensed water, the condensed water needs to be discharged out of the cavity 2 in time through a drainage structure, otherwise, the water vapor pressure gathered inside the cavity 2 is too large, and the subsequent residual condensed water is not easy to clean and is easy to breed a large amount of bacteria. In the present embodiment, a gap 13 (see fig. 15) for guiding out water is provided between the flat plate 22 and the rear plate 24, and condensed water generated inside the cavity 2 can be discharged out of the cavity 2 through the gap 13 in time.

More specifically, the guide water tank 4 is provided at a lower portion of the hot air back panel 3 and below the gap 13 between the flat plate 22 and the rear plate 24 in order to guide out water, and the steam and the condensed water discharged from the cavity 2 through the gap 13 naturally fall to the guide water tank 4 and are discharged along the guide water tank 4.

The water to be discharged (the water to be discharged includes water obtained by condensing water vapor or other water to be discharged) in the cavity 2 is discharged out of the cavity 2 through the gap 13, flows along the guide water tank 4, and falls to the water discharge tank 10.

In the prior art, the circuit board mounting plate and the drainage channel are generally separately arranged to realize different functions, but such a structure may cause an increase in size and an increase in the number of components due to the separate molding of the circuit board mounting plate and the drainage channel, and may cause water to flow onto a metal component or a bottom plate below due to a risk between the circuit board mounting plate and the drainage channel. In contrast, in the present embodiment, the water drainage structure of the guide water tank 4 and the water drainage tank 10 is adopted, the water in the cavity 2 flows into the guide water tank 4 of the hot air back panel 3 through the slit 13, and the guide water tank 4 guides the water into the water drainage tank 10 integrated with the circuit board mounting plate 9. Therefore, in the embodiment, the drainage channel 10 and the circuit board mounting plate 9 form an integrated structure, so that the circuit board mounting plate 9 is compact and reliable in structure and can be applied to small-sized products; meanwhile, the number of parts can be reduced, the mounting structure is simplified, and the manufacturing cost is obviously reduced.

Further, as shown in fig. 9, the drain grooves 10 extend in a downward inclined manner in a direction away from the hot air back panel 3, that is, the drain grooves 10 extend in a downward inclined manner in a direction away from the guide water groove 4, and the upstream end of the drain grooves 10 is located at the downstream end of the guide water groove 4. The drain grooves 10 are formed to be inclined in a horizontal direction (a direction parallel to the bottom of the steaming and baking oven 1), so that it is possible to ensure that water from the guide tub 4 smoothly flows down through the inclined drain grooves 10 without being caught in the drain grooves 10. The inclination angle is not particularly limited as long as the water flowing down from the guide water tub 4 can be ensured to flow smoothly along the drain tub 10, and is preferably about 5 degrees.
