In this embodiment, the side of the working chamber of the box body where the working chamber is opened is referred to as a front side or an outer side, and a rear side or an inner side and left and right sides are defined accordingly.

In addition, the lower side edge of the box door can be rotatably connected with the box body, so that when the box door is opened, the box door can be accurately and reliably positioned at the approximately horizontal maximum opening position under the action of self gravity, and therefore materials can be conveniently taken and placed in the box body, and the situation that the materials are blocked to be taken and placed due to random rotation of the box door is avoided.

It is known that the higher temperature portion of the heated stored water in the tank rises. Accordingly, the temperature of water in the water tank may be high or low, and accordingly, the temperature of the upper portion of the door may be higher than that of the lower portion of the door. The control component can be arranged on the connecting frame below the water tank, so that the control component avoids the region with higher temperature at the upper part of the box door as much as possible, the control component is favorable for keeping the proper working temperature, the service life is prolonged, the failure rate is reduced, the transverse length size of the box door and the box body is favorable for reducing, and the placement of the steam oven in a kitchen is facilitated.

It is known that when a steam oven enters a steaming process, a large amount of steam is generated in a working chamber, and the steam can enter the interior of the oven door through a matching gap between the front and rear surface layers of the oven door and the connecting frame to form condensed water.

For this purpose, as shown in fig. 2 and 3, a water blocking rib 23 is provided on the connection frame above the control part, and a waste water box 13 connected to the box body is provided below the box door, and an opening is provided at the upper part of the waste water box.

When steam enters the interior of the box door and forms condensed water, the water retaining ribs can effectively shield the control component, and the problems of short circuit, corrosion and the like caused by the fact that the condensed water flows downwards and drops on the control component are avoided. And the condensed water dropping on the water retaining ribs can converge and concentrate along the upper surfaces of the water retaining ribs and fall into the wastewater box.

Particularly, the projection of at least two ends of the water retaining rib in the vertical direction is positioned in the opening at the upper part of the wastewater box. Like this, when the comdenstion water is gathered a quantitative time at manger plate rib upper surface, the comdenstion water can be followed the upper surface both ends of manger plate rib and flowed out to in all flowing into the opening of waste water box, avoid the comdenstion water to drip and place the face on and influence user experience.

Preferably, the water blocking rib comprises a main blocking strip 231 arranged transversely and an auxiliary blocking strip 232 extending downwards from the left end and the right end of the main blocking strip to the lower side of the connecting frame, so that the water blocking rib is approximately trapezoidal. Therefore, the condensed water dropping on the main barrier strip can flow to two sides quickly to reach the auxiliary barrier strip, and then is converged with the condensed water dropping on the auxiliary barrier strip and flows out of the end part of the auxiliary barrier strip to enter the wastewater box. Because the end part of the auxiliary barrier strip is connected to the lower side of the connecting frame, the control component can be comprehensively shielded, and further, the condensed water is ensured to completely flow into the wastewater box, and the safety performance is further improved.

Preferably, the main barrier strips are arranged to be gradually reduced from the middle to the two ends, that is, the main barrier strips can be herringbone or arc-shaped, so that the whole water retaining rib is roughly in the shape of a herringbone, the rapid flowing of condensed water is facilitated, and the formation of the residual condensed water on the upper surface of the water retaining rib is avoided.

Furthermore, the main barrier strip is in an inverted V shape, so that the processing and manufacturing are simplified. The included angle alpha between the main barrier strips at the left side and the right side and the horizontal plane can be controlled in the following range: alpha is more than or equal to 1 degree and less than or equal to 3 degrees, thereby not only effectively accelerating the flowing speed of the condensed water, avoiding the condensed water from accumulating on the water retaining ribs and enabling the lower parts of the water retaining ribs to form enough containing space for containing the control component, but also being beneficial to reducing the area of the box door and the overall dimension of the steam oven.

The connecting frame can be a plastic piece manufactured by an injection molding process, so that the water retaining ribs and the supporting base plate can be integrally molded, condensed water is prevented from permeating downwards from the joints of the water retaining ribs and the supporting base plate and dripping onto the control part, and the water retaining effect and the safety are favorably further improved on the premise of improving the manufacturing and assembling efficiency.

As another preferred scheme, the surface layer of the inner side comprises a heat insulation frame 211 shaped like a Chinese character kou, the water tank extends into an inner hole of the heat insulation frame, and heat insulation glass 212 made of toughened glass is arranged in an opening at the rear side of the inner hole of the heat insulation frame. Of course, the insulating glass should cover the opening of the working chamber so as to effectively prevent heat in the working chamber from being conducted to the outer surface of the door, the insulating frame should include a rear plane and be formed by die-casting of aluminum alloy, and the insulating glass may be bonded to the insulating frame by means of bonding or the like so as to form an assembly member and have a flat rear surface on the inner surface.

The inner surface layer and the outer surface layer can be connected and assembled through screws and other simple modes, and auxiliary structures such as connecting pipelines can be arranged between the inner surface layer and the outer surface layer. Furthermore, the insulating frame may even be stamped and formed from stainless steel sheet material. For the heat insulation frame formed by die casting or even punch forming, a corresponding clamping groove can be formed in the inner side of the heat insulation frame, and then the sealing strip is embedded in the clamping groove in an interference manner, so that reliable sealing connection between the water retaining rib and the surface layer of the rear side is ensured.

In order to further improve the waterproof effect of the water retaining rib, as shown in fig. 4, a sealing strip 5 can be arranged on the front side of the surface layer on the inner side, and the rear side edge of the water retaining rib is embedded in the sealing strip, so that the water retaining rib and the surface layer on the rear side form sealing connection. At the moment, the water retaining rib separates between the surface layer at the rear side and the supporting substrate to form an upper sealed and separated cavity and a lower sealed and separated cavity, and the control part is positioned in the cavity at the lower side. When the condensed water in the cavity on the upper side of the water retaining rib in the box door flows downwards along the rear surface layer and the supporting substrate and drops on the water retaining rib, the condensed water can flow towards two sides quickly and enter the wastewater box, and the condensed water is thoroughly prevented from seeping into the cavity on the lower side of the water retaining rib to corrode the control part.

Alternatively, as shown in fig. 5, a mounting groove 222 may be formed on the support substrate at the front side of the connection frame, and a sealing ring 24 surrounding the mounting groove may be formed at the front side of the connection frame. When the surface layers on the front side and the rear side are assembled into the box door with the connecting frame, the front side surface layer is attached to the supporting base plate of the connecting frame, and the sealing ring on the connecting frame is closely attached to the front side surface layer, so that the mounting groove forms a sealing cavity for accommodating the control part. At the moment, the top wall and the side wall of the mounting groove form the water retaining rib so as to effectively prevent condensed water from entering the mounting groove to corrode the control part and enable the condensed water to fall into the wastewater box along the water retaining rib.

And finally, the width of the wastewater box can be matched with that of the box body, the wastewater box extends forwards from the lower part of the box body to the lower part of the box door, and an opening is formed in the position, corresponding to the lower side of the box door, of the upper part of the wastewater box. Thus, the condensed water in the tank body, especially the inner side of the tank door, can naturally flow into the waste water tank. When the user is with clean box inside work chamber such as wet cloth, can conveniently with a small amount of dirty water propelling movement of rag with clean formation to box front side open-ended lower border department, and then flow into in the waste water box through the opening to make things convenient for the subsequent maintenance and the cleanness of steam oven, be favorable to keeping the clean and tidy of kitchen.
