When the dish is steamed by cooking, the material can be put into the working cavity, then the function of steaming is started, the steam generator at the moment is electrified to heat up quickly, then the water pump is started to convey the stored water in the water tank to the steam generator, and the water is quickly vaporized to form steam during the steam generator. When the water pump makes water continuously drop on the steam generator, continuous steam can be formed, thereby cooking food.

Since the steam oven is the prior art, the features and structures of the prior art, such as the steam generator, the control part, and the water pump, are not described in this embodiment.

In order to facilitate the assembly and manufacture of the box door, the box door is of a splicing structure. Specifically, the box door comprises a surface layer 21 which is attached to the inner side and the outer side of the box door, a flat cavity is formed inside the surface layer on at least one side, and the flat cavity forms the water tank for storing water. That is to say, the chamber door is the sandwich structure that has the water tank inside that the equipment of interior outer skin formed, under the prerequisite of guaranteeing the effective volume of water tank, can make full use of the inner space of chamber door to promote the thermal-insulated effect of chamber door effectively.

It will be appreciated that the tank may be formed integrally with the skins to form one component and that the assembly of the door may be carried out by simply assembling the two components together, thereby greatly simplifying the manufacture and assembly of the door, and particularly the tank.

It is known that, when the steam oven works, the temperature rise of the part of the box door corresponding to the opening of the working cavity of the box body is the highest, and water has larger specific heat capacity. Therefore, the area of the water tank can completely cover the opening of the working cavity, so that the water stored in the water tank can fully absorb the heat of the working cavity, the heat in the box body is prevented from being transferred to the outer surface of the box door, the outer surface of the box door can be always at a proper temperature, and the safety of the steam oven in use is improved.

Because the water tank is arranged in the box door, the size of the functional cavity can be fully reduced, the whole size of the box body is further reduced, and the placement of the steam oven in a kitchen space is facilitated.

Certainly, the temperature of the stored water in the water tank rises after the stored water absorbs the heat of the working cavity, and when the stored water in the water tank is conveyed to the steam generator, the stored water is favorable for vaporization of the water, so that the energy consumption of the steam generator is reduced.

In order to facilitate operation and control, the control part can be arranged between the inner surface layer and the outer surface layer of the box door, and specifically, the control part comprises a display screen and a touch control key, so that the working program of the steam oven is displayed and controlled through the outer surface of the box door, and the attractiveness of the steam oven is improved.

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 first preferable mode, the outer surface layer includes a transparent heat insulating layer 211 and a door frame bracket 212 provided on the inner surface of the heat insulating layer, and the door frame bracket is attached to the inner surface layer. An annular side wall 213 is integrally formed on the inner side surface of the heat insulating layer and extends inward, and forms an open cavity, and a sealing cover plate 214 is sealingly connected to the opening of the cavity, thereby forming a water tank for storing water.

That is, the water tank is integrally formed on the inner side surface of the transparent heat insulation layer, so that the outer side surface layer can be made of high-temperature-resistant transparent plastics such as acrylic through a molding process, the manufacturing process of the outer side surface layer and the water tank is greatly simplified, and the assembly of the box door is facilitated. In addition, the transparent heat insulation layer is favorable for a user to observe the water storage condition in the water tank so as to add water into the water tank in time. The box door with the water tank has a good heat insulation effect, the heat of the working cavity is blocked by the inner surface layer and is fully absorbed by the water outlet in the water tank, and the temperature of the heat insulation layer and the water tank is not too high, so that the heat insulation layer and the water tank made of plastic can sufficiently bear the temperature during working.

It should be noted that, for the cavity made of plastic, the sealing cover plate is preferably made of plastic with the same material, and can be hermetically connected with the cavity through processes such as ultrasonic welding, glue bonding and the like, so as to form the water tank integrally connected with the heat insulation layer. Of course, the sealing cover plate can also be fixedly connected with the side wall of the cavity in a screw connection mode, and a sealing ring is arranged between the sealing cover plate and the cavity to form a sealed water tank.

Certainly, the heat insulation layer and the cavity can also be made of high-temperature-resistant toughened glass, and the sealing cover plate can also be made of a toughened glass sheet and connected with the cavity into a whole through a welding process.

Because the doorframe bracket is positioned at the periphery of the water tank, the high temperature of the working cavity can not directly act on the doorframe bracket, and therefore, the doorframe bracket can be preferably manufactured into an integrated plastic part together with the heat insulation layer and the cavity through a molding process, thereby not only facilitating the processing and the manufacturing, but also improving the strength and the rigidity of the outer surface layer. Of course, the door frame support can also be formed by plastic molding with better temperature resistance, even aluminum alloy die-casting, and is connected with the heat insulation layer by methods such as screw connection and the like, so that the door frame support has good heat resistance.

Preferably, we can set up the rectangular shape handle 5 of horizontal arrangement on top of the outside top layer, both ends set up spliced pole 51 about the handle, set up the fastening screw that corresponds with the spliced pole on the door frame support, fastening screw passes the door frame support, the spliced pole threaded connection of insulating layer and handle, both made things convenient for the assembly of chamber door, can avoid leaving any exposed fastener on handle and outside top layer again, be favorable to the pleasing to the eye of chamber door surface, convenience of customers opens and close the chamber door simultaneously, promote the joint strength of handle and chamber door, make outside top layer and handle constitute a subassembly that is used for assembling the chamber door.

As another preferred scheme, the surface layer at the inner side comprises a heat insulation frame 215 in a shape of a Chinese character kou, so that an inner hole matched with the size of the water tank is formed in the middle, the inner side surface of the heat insulation frame is a side wall in a shape of the Chinese character kou, and the water tank on the heat insulation layer extends into the inner hole of the heat insulation frame. In addition, the insulating glass 216 is disposed in the inner opening of the inner hole of the insulating frame, so that heat in the working chamber can be effectively prevented from being conducted to the water tank and further to the outer surface of the box door. Because the opening of the heat insulation frame and the working cavity are staggered, the heat insulation frame can be conveniently made of high-temperature-resistant plastics such as PC and nylon through a molding process, the heat insulation glass can be connected to the heat insulation frame in a bonding mode, a clamping mode and the like, the heat insulation glass and the side wall in the shape of the Chinese character kou form a surface of a certificate, and the surface forms the inner side face of the box door. The heat insulation frame made of plastic facilitates connection and assembly between the inner surface layer and the outer surface layer through simple methods such as screws, and is beneficial to arranging auxiliary structures such as connecting pipelines between the inner surface layer and the outer surface layer.

Preferably, 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 random rotation of the box door is avoided.

In addition, set up waste water box 13 in the lower part of box, 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, flushes until waste water box and chamber door front side top layer, and 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.

As mentioned above, the control member of the present invention is disposed between the inner and outer surface layers of the door. Preferably, the control means is also arranged between the inner and outer skins on the underside of the tank, so as to stagger the working chambers of the tank. Specifically, the control part can be arranged in the doorframe bracket of the front side surface layer; or in the heat-insulating frame of the rear surface layer, and corresponding through holes are arranged on the doorframe bracket, so that the display screen, the control keys and the like of the control component are positioned in the through holes.

The water tank is flat, so that the water tank has a small thickness and a high height. The water heated in the water tank rises due to expansion, and the 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 and low temperatures, 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 side of the water tank can avoid the higher temperature area on the upper part of the box door as far as possible, so that the control component can keep a 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 reduced, and the placement of the steam oven in a kitchen is facilitated.

It should be noted that the functional cavity can be arranged at the rear part of the waste water box below the box body or at the rear part of the box body, so as to reduce the external dimension of the front surface of the box body as much as possible. Of course, the functional component should be located in the functional cavity, so that the functional component is effectively isolated from the high-temperature working cavity.

Alternatively, the control member may be disposed within the door between the inner and outer skins on the lower or right side. On one hand, the box door can cover 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. On the other hand, the control component can avoid the central area of the high-temperature working chamber, thereby effectively avoiding the control component from being damaged due to high temperature and fully utilizing the inner space of the box door.

In order to facilitate the drainage of the water stored in the water tank, as shown in fig. 3, a drainage port 22 can be arranged at the lower part of the doorframe bracket, the drainage port is communicated with the bottom of the water tank through a connecting pipeline, and the downward opening of the drainage port 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.

In order to conveniently inject water into the water tank, a water injection port 23 can be formed in one side of the upper portion of the doorframe bracket 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. Because the water filling port sets up on connection frame's upper portion, consequently, be favorable to in the water filling port water gets into the water tank fast to but the volume of make full use of water tank appears from the reverse phenomenon that overflows of water filling port when the water level in the water tank rises.

Further, as shown in fig. 4, a water guide member 24 is provided in the water filling port so as to be laterally movable, and a water guide groove 241 extending to the inside is provided above the water guide member.

When a user opens the box door to enable the box door to be inclined, the user can pull out the water guide part from the inside to the outside of the water filling opening, then water is filled into the water guide groove with the upward opening by devices such as a kettle, and the like, and water can flow into the water filling opening along the water guide groove. That is to say, the water guide component enables the water filling opening to be in a closed state at ordinary times, so that the opening and closing of the box door are facilitated, and external dust and the like can be effectively prevented from entering the water filling opening to cause pollution. When water needs to be filled, the water guide part is pulled out outwards, namely the water filling port is equivalently extended outwards, so that water can be filled conveniently for users.

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 is understood that various changes and modifications other than those described in the preferred embodiments described above may be made by those skilled in the art without departing from the spirit of the invention, and the scope of the invention is defined by the appended claims.
