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.

As a preferred scheme, the lower side edge of the box door can be rotatably connected with the box body, and when the box door is turned downwards and opened, the box door can be accurately and reliably positioned at the maximum opening position which is approximately horizontal under the action of self gravity, so that materials can be conveniently taken and placed in the box body, and the situation that the materials are prevented from being taken and placed due to the random rotation of the box door is avoided.

Preferably, the upper part of the outer surface layer is provided with a transversely arranged strip-shaped handle 5, the left end and the right end of the handle are provided with connecting columns, the connecting frame is provided with fastening screws corresponding to the connecting columns, and the connecting columns of the connecting frame, the outer surface layer and the handle are fixedly connected through the fastening screws. That is, there are no exposed fasteners on the handle and the outer skin, while facilitating the assembly of the door.

Furthermore, we can set up waste water box 13 in the lower part of box, and the width of waste water box matches with the width of box, and the front side of waste water box is preceding to extend and expose the box, and until waste water box and chamber door front side top layer flush, the waste water box upper portion that exposes the box sets up the opening that corresponds with chamber door downside limit. Thus, the condensed water in the tank body, especially the inner side of the tank door, can naturally flow downwards 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.

It should be noted that the control chamber may be disposed at the rear of the waste water box below the tank body, or at the rear of the tank body, so as to minimize the external dimensions of the front surface of the tank body.

Furthermore, the box body is arranged in a cuboid shape, and correspondingly, the box door is arranged in a rectangle covering the front side of the whole box body, so that the steam oven has a uniform front side surface, the attractiveness of the product is improved, and the structure of the front side surface of the box body can be simplified. The connecting frame is enclosed into a shape like a Chinese character 'kou' by the four supports, so that the connecting frame and the surface layer are enclosed to form a rectangular mounting cavity, the water tank is arranged into a flat rectangle matched with the mounting cavity, and the volume of the water tank is favorably improved on the premise of not increasing the thickness of the tank door, so that the requirement of cooking food is met.

Furthermore, the water tank may be preferably configured in a rectangular shape matching the opening of the working chamber in order to effectively isolate the heat of the working chamber from being transferred to the outer surface of the door, while the control member is disposed on the bracket on the right side corresponding to the control chamber. Because the control chamber on the right side of the box body can not form high temperature during working, when the control part is arranged on the support on the right side, the control part can be enabled to avoid the high-temperature working chamber, the control part can be effectively prevented from being damaged due to high-temperature baking, and the inner space of the box door can be fully utilized.

Of course, the control member may be provided on the lower bracket. Since the water tank has a flat rectangular shape, that is, has a small thickness and a high height. Therefore, the stored water heated in the water tank rises due to expansion, and the stored water with lower temperature sinks to the lower part of the water tank, so that the water temperature of the water tank is characterized by high temperature and low temperature, and correspondingly, the temperature of the upper part of the box door is higher than that of the lower part of the box door. The control component arranged on the lower bracket can avoid the region with higher temperature at the upper part of the box door as far as possible, so that the control component can keep proper working temperature, the service life can be prolonged, and the failure rate can be reduced.

As another preferred scheme, as shown in FIG. 3, a drain port 24 is provided on the bracket on the lower side of the connection frame, the drain port is communicated with the bottom of the water tank through a connection pipeline, and the opening of the drain port facing downwards faces the opening of the waste water box. After the steam oven is used, a user can open the water outlet to discharge the stored water in the water tank into the waste water box. When the steam oven is reused, the user may refill the water tank with clean water to ensure cleanliness and hygiene of the cooked food. Because the position of the water outlet is lower than the bottom of the water tank, when a user opens the water outlet, residual water in the water tank can be discharged outwards through the water outlet, and therefore water accumulation at the bottom of the water tank is avoided.

Of course, it is necessary to provide a stop valve such as a ball valve at the drain port, so as to facilitate the opening and closing control of the drain port by the user. When a user needs to drain the residual water in the water tank, the tank door can be partially opened to enable the tank door to be inclined, then the stop valve is opened, and the residual water in the water tank can be drained into the waste water tank through the water outlet under the action of self gravity. Of course, the user can also open the box door completely to open the stop valve at the lower part of the box door conveniently, and at the moment, the residual water in the water tank begins to flow out from the water outlet and enter the waste water box. Then the user can turn the box door upwards, so that the water tank is in an upright state, and the residual water in the water tank can be discharged into the waste water box quickly.

It can be understood that a flexible pipeline extending into the opening of the waste water box can be arranged at the water outlet to ensure that residual water in the water tank can completely flow into the waste water box through the pipeline when the box door is in a partially opened or completely opened state, so that the phenomenon that the residual water leaks out is avoided.

In order to conveniently inject water into the water tank, a water injection port 25 can be arranged at the upper part of the connecting frame and is communicated with the water tank through a water injection pipeline.

When food needs to be cooked, a user can open the box door at an angle first to enable the box door to be inclined so as to expose the water filling port on the box door, and at the moment, the user can pour water into the water filling port by using instruments such as a kettle and the like.

Preferably, we can set up the water filling port in the upper portion of connecting the frame left side to make the height of water filling port be higher than the water tank top surface, in order to be favorable to shortening the length of water injection pipeline, reduce the dust that falls into in the water filling port. When the water tank is filled with water, the water in the water tank cannot reversely overflow from the water filling port, so that the volume of the water tank can be completely utilized, the thickness of the water tank is reduced as much as possible on the premise of ensuring the capacity of the water tank, and the thickness of the box door is favorably reduced.

Certainly, we can also set up the water filling port on the side on the connection frame to furthest promotes the height of water filling port, convenience of customers passes through the water filling port and toward the water tank in water injection, and be favorable to water injection intraoral water to get into in the water tank fast.

Furthermore, a one-way valve which can lead the water injection pipeline to be conducted from outside to inside can be arranged in the water tank. That is, the water filling line allows only water to flow into the water tank from the water filling port, but water in the water tank cannot flow out of the water filling port through the water filling line. When water is injected into the water tank through the water injection port, the one-way valve is in an open state, and external water can smoothly flow into the water tank through the water injection pipeline; when the water tank finishes water injection, the one-way valve which is communicated in one way can effectively prevent the stored water in the water tank from flowing outwards through the water injection pipeline. Especially, the user is in the use, need overturn downwards and open the chamber door, and at this moment, the water tank is in the state of keeping flat, and the water injection pipeline is in the off-state from inside to outside, and at this moment, the water storage in the water tank that the check valve can avoid keeping flat passes through the water injection pipeline and outwards flows from the water filling port, and then ensures the normal use of steam oven.

It should be noted that when the water pump is started to convey the stored water in the water tank to the steam generator, a negative pressure is formed in the water tank, and at this time, the external air can enter the water tank through the water injection port and the water injection pipeline in a conducting state from outside to inside, so that the water pump can smoothly pump the stored water in the water tank.

Preferably, as shown in fig. 4, a silicon sheet 6 is disposed on the inner side wall of the water tank, a connecting convex pillar 61 embedded on the inner side wall of the water tank is disposed on one side of the silicon sheet, and the other side of the silicon sheet covers the water inlet hole 31 connected to the water injection pipeline. When a user injects water into the water tank through the water injection port, the pressure of the water can push the silica gel sheet away, and the silica gel sheet is elastically bent and inclined. When the chamber door is opened and is in the horizontality, the water storage in the water tank extrudes the silica gel piece from inside to outside end, makes the silica gel piece closely paste and lean on the water tank inside wall, and then the inlet opening on the shutoff water tank lateral wall, avoids the water storage in the water tank to spill over outwards effectively.

Finally, the inner and outer surface layers and the water tank can be made of transparent materials such as glass, transparent plastics and the like. Preferably, the outer surface layer can be made of heat insulation glass and is embedded on the connecting frame, the inner surface layer comprises a rectangular mounting frame 221 with a periphery, a piece of heat insulation glass 222 is embedded in an inner hole of the mounting frame, the mounting frame is connected with the connecting frame through screws, the outer surface layer, the connecting frame, the mounting frame and the heat insulation glass surround to form the mounting cavity, the inner surface layer is convenient to be connected with the connecting frame into a whole, and a user can observe the cooking state of food in the working cavity conveniently.
