Figure 6 and Figure 7 In order to better illustrate the present oven, the following are schematic diagrams of the structure from the front and top directions after the water tank cover P is removed.

[0032] Among them Figure 1 As shown, the oven body includes a water tank cover P. Figure 6 and Figure 7 In the figure, since the water tank cover P is removed, the three electromagnetic pumps and three water tanks on the top of the oven can be seen as a top view, namely the first electromagnetic pump Y1, the second electromagnetic pump Y2, the third electromagnetic pump Y3, the first water tank Z1, the second water tank Z2, and the third water tank Z3.

[0033] Figure 8 As a schematic diagram of the oven door structure in detail in this scheme, it serves as the basis for the subsequent description of the embodiments.

[0034] In one embodiment, Figure 1-Figure 8 As shown, an oven is provided, including a box body and a box door, wherein: the box body includes a box frame, an inner tank and a lock body, the inner tank is located in the box frame, the surface of the inner tank is coated with a heat-insulating nano layer, and a layer of heat-insulating cotton is laid on the surface of the heat-insulating nano layer, and the lock body is arranged on the right side of the box frame.

[0035] The box door comprises a three-layer door, a vacuum layer and a heat-insulating layer, wherein the three-layer door comprises a first-layer door, a second-layer door and a third-layer door;

[0036] Specifically, the first door includes a first tempered glass 111 and a fixed baffle 112 , the outer side of the first tempered glass 111 is attached to the inner side of the main frame 122 , and the fixed baffle 112 is arranged on the inner side of the first tempered glass 111 and fastened by bolts 113 .

[0037] The second door is located at the middle layer, and a sealed main frame 122 is provided between the second door and the first door. Specifically, the second door also includes a second tempered glass 121, which is attached to the outer side of the main frame 122 and is also fastened by bolts.

[0038] The third door is located at the outer layer, and further comprises a third tempered glass 131 and a column, wherein the column is bonded to a side of the third tempered glass 131 close to the second door.

[0039] Both ends of the main frame 122 are longer than the first door and the second door. The portion of the left end of the main frame 122 that exceeds the first door and the second door is connected to the box body through the first hinge 123, and is connected to the third door through the second hinge 132; the portion of the right end of the main frame 133 that exceeds the first door and the second door is provided with a lock, which matches the lock body and is positioned opposite to it; the vacuum layer is located between the first door and the second door; and the heat insulation layer is located between the second door and the third door.

[0040] The above embodiment is described in detail below:

[0041] The first layer door: located in the innermost layer, seals the inner tank and directly contacts with high temperature gas.

[0042] Materials: The first tempered glass 111 is 5 mm thick tempered glass.

[0043] Structure: The first tempered glass 111 has a mounting hole, which fits with the main frame 122, and the first tempered glass 111 is fixed to the main frame 122 by bolts.

[0044] The second door is located in the middle layer, and it has the function of heat insulation, forming a vacuum space with the first door. Although a vacuum space is formed, due to the high temperature of the inner liner, the temperature of this layer of glass is still high to the touch, and there is a risk of scalding.

[0045] Materials: The main frame 122 and related metal parts are made of stainless steel, and the second tempered glass 121 is made of 5 mm thick tempered glass.

[0046] Structure: The main frame 122 of the door and the oven body are connected by a special hinge plate (i.e., the first hinge 123), and the second tempered glass 121 is bonded to the inner side of the main frame 122 by high temperature resistant glue and pressed by a fixing plate. The main frame 122 is airtight and can support the first tempered glass and the second tempered glass to form a conventional vacuum space, and how to achieve vacuum by exhausting air is a prior art.

[0047] The third door: It is located on the outermost layer and is a glass door added to avoid burns. When the oven is working, an air-filled insulation layer is formed between the third door and the second door. Through the setting of the insulation layer, when the operator touches the third door (the outermost door) with his hand, the temperature is not high, which is safe.

[0048] Materials: The columns are made of stainless steel. Figure 8 As shown, the column is divided into two sides, the column 133A is close to the oven door, and the column 133B is far away from the oven door, a dedicated second hinge, and 5mm thick tempered glass.

[0049] Structure: The third tempered glass 131 is bonded to the columns on the left and right sides with high temperature resistant glue, and a glass clamp is installed to fix it, so as to form a vacuum layer with the first door. This structure is simple, light, reliable, and can effectively avoid the risk of burns.

[0050] Combination Figure 7 and Figure 8 It can be clearly seen that the three-layer glass is fixed to the columns and main frame mostly by bolts or screws and heat-resistant rubber pads. This setting can better stabilize the structure of the three-layer door and avoid unexpected situations such as deformation or unstable connection due to long-term high-temperature heating.

[0051] In one embodiment, the lower end of the main frame is designed with a bevel groove beyond the first and second doors. Figure 7 It can be seen more clearly from the picture after removing the water tank cover P that the side of the oven door adopts the design of the bevel groove 125 as a side handle, so as to achieve the invisible side door handle and avoid the situation where adding a handle on the front affects the overall appearance.

[0052] In one embodiment, Figure 8 As shown, the cabinet door also includes a liquid crystal touch screen structure 2, which is located on the outside of the portion of the right end of the main frame that exceeds the first and second door layers and is flush with the third door layer, and includes a liquid crystal screen 21.

[0053] Specifically, the outer surface of the liquid crystal touch screen structure 2 is flush with the outer surface of the third layer door, so that the overall outer surface is smooth.

[0054] In one embodiment, the liquid crystal touch screen structure 2 further includes a heat dissipation device 22 , which is disposed below the liquid crystal screen 21 and is used to dissipate heat from the liquid crystal screen 21 .

[0055] Specifically, a heat dissipation device 22 is provided at the upper end of the liquid crystal touch screen structure 2, which is usually a small fan, and other heat dissipation methods such as coolant can also be considered. A cover plate 221 is provided on the heat dissipation device 22 to fix the heat dissipation device 22, and the liquid crystal touch screen structure 2 is installed as a whole on the right side of the door.

[0056] In one embodiment, since the hinge connections of the present solution are all detachable, that is, the hinges between the main frame and the box body, and between the frame assembly machine and the third-layer door are all detachable, after the actual use of the oven, the first-layer door, the main frame and the second-layer door can be separately disassembled and cleaned from the third-layer door, thereby realizing the detachable cleaning of the oven door and improving the operational convenience of cleaning the oven door.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
