The present application proposes an oven door body. It can be understood that the oven door body of the present application can be applied to an independent oven product, and can also be applied to a combined kitchen appliance, which includes an oven.

As shown in conjunction with FIGS. 1 to 6 , in some embodiments of the present application, an oven door 3000 includes an inner door 3100 , a window panel 3200 , a support plate 3300 , a cover 3400 and a handle 3500 .

Take a combination cooker including an oven as an example, wherein the oven includes a box body 1000 and an oven door body 3000, the box body 1000 can be understood as an outer shell, and can also be understood as an inner container. 1000 is provided with an inlet and outlet 1100 communicating with the accommodating cavity, through which the food can be taken and placed, for example, the food can enter into the accommodating cavity through the inlet and outlet 1100 to be baked and cooked, and when the baking and cooking are completed Then leave the accommodating cavity through the inlet and outlet 1100 , that is to say, the inlet and outlet 1100 is a port connecting the inside and outside of the box body 1000 .

The oven door 3000 is configured to be closed and open relative to the inlet and outlet 1100. When the oven is in a baking state or when the oven is not in use, the user can control the oven door 3000 to close the inlet and outlet 1100. At this time, food cannot pass through the inlet and outlet 1100 and After leaving the box 1000 and the oven is finished baking, the user can control the oven door 3000 to open the inlet and outlet 1100 , at this time, the ingredients can leave the box 1000 through the inlet and outlet 1100 .

It can be understood that, the oven door 3000 can be closed and the inlet and outlet 1100 can be opened in many ways.

For example, the oven door 3000 can reciprocate linearly relative to the cabinet 1000 so as to open and close the inlet and outlet 1100. Specifically, the oven door 3000 moves linearly relative to the cabinet 1000 and away from the cabinet 1000. At this time, the oven door 3000 is opened. The entrance and exit 1100 , the oven door 3000 moves linearly relative to the box body 1000 and faces the box body 1000 , and the oven door 3000 closes the entrance and exit 1100 at this time.

It is also possible that the oven door 3000 is configured to be rotatably connected with respect to the inlet and outlet 1100, and the oven door 3000 and the box body 1000 may be rotatably connected, and the bottom of the oven door 3000 is rotatably connected to the box body 1000 through a hinge. , with the bottom of the oven door 3000 as the center of rotation, the top of the oven door 3000 can be rotated from top to bottom to open the inlet and outlet 1100 , and can be rotated from bottom to top to close the inlet and outlet 1100 .

In order to facilitate the user to observe the situation inside the cabinet 1000 in real time, the oven door 3000 is provided with a transparent window through which the user can observe the inside of the cabinet 1000 .

Specifically, the inner door 3100 of the oven door 3000 is a component close to the inlet and outlet 1100, and the inner door 3100 is generally a sheet metal part. When the oven door 3000 closes the inlet and outlet 1100, the inner door 3100 abuts against the inlet and outlet The periphery of 1100 and sealing inlet and outlet 1100. The inner door 3100 is provided with a first through hole 3111, which can be punched out on the inner door 3100. The first through hole 3111 provides a basis for the user to observe the inside of the box body 1000 through the window plate 3200.

The window plate 3200 is a transparent component, so that the user can observe the internal conditions of the box body 1000 through the window plate 3200 and the first through hole 3111 . The window plate 3200 can be made of various materials, such as glass or polymer material, as long as the window plate 3200 can allow light to pass through. The window plate 3200 is installed on the outside of the inner door 3100, the side of the inner door 3100 close to the entrance and exit 1100 is the inside, and the side away from the entrance and exit 1100 is the outside, and the window plate 3200 abuts against the peripheral part of the first through hole 3111, that is The window plate 3200 abuts against the outside of the inner door 3100, thereby blocking the first through hole 3111. Here, blocking the first through hole 3111 means that the area of the window plate 3200 is larger than the area of the first through hole 3111, so that the window plate The 3200 may abut against the edge of the first through hole 3111 from the center of the first through hole 3111 and the periphery of the first through hole 3111 , so that the inner door 3100 supports the inner side of the window panel 3200 .

The window plate 3200 also needs to be fixed by setting the support plate 3300 and the cover 3400 . The support plate 3300 is arranged on the inner door 3100, that is, the support plate 3300 is integrally fixed on the inner door 3100, and is located on the outside of the inner door 3100. The connection between the support plate 3300 and the inner door 3100 can be in various ways, such as welding, screwing, clamping, etc. Then wait. The cover 3400 is also disposed on the outside of the inner door 3100 and also on the outside of the support plate 3300 , that is to say, the cover 3400 can cover the support plate 3300 and constitute at least a part of the outer surface of the oven door 3000 . A clamping cavity 3600 is formed between the supporting plate 3300 and the covering member 3400, and the bottom of the viewing window plate 3200 is inserted into the clamping cavity 3600 to be fixed, and is mutually fixed with the supporting plate 3300 and the covering member 3400, thus forming a stack of three layers. Combined structure, strengthen the structural strength.

It can be understood that there are various ways to fix the window plate 3200 to the cover 3400 and the support plate 3300 . For example, the window plate 3200 is connected to the support plate 3300, and the cover member 3400 is connected to the window plate 3200, so as to achieve the fixing of the three. It is also possible that the support plate 3300 is connected to the cover member 3400 to clamp the window plate 3200, so that the fixing of the three can also be realized. It is also possible that the support plate 3300, the window plate 3200 and the cover 3400 are all fixed to each other. No matter what kind of fixing method is adopted, as long as the support plate 3300, the window plate 3200 and the cover member 3400 can be fixed into a three-layer laminated structure.

The cover 3400 is provided with a handle 3500, and the handle 3500 and the cover 3400 are prepared through an integral molding process. For example, the handle 3500 and the cover 3400 are made of the same material, so they can be injection molded or molded at one time. The handle 3500 and the cover 3400 can also be made of two different materials, so that they can be produced by an over-injection molding process. For example, the cover 3400 and the handle 3500 are integrally molded by resin, and the resin material can not only make the combination of the cover 3400 and the handle 3500 have higher structural strength, but also play a role of heat insulation.

Since the handle 3500 and the cover 3400 are integrally formed, the structural strength between the handle 3500 and the cover 3400 is relatively high. With the three-layer laminated structure formed between the cover 3400, the window plate 3200 and the support plate 3300, the handle 3500 and The cover 3400 is firmly fixed as a whole, and the handle 3500 has high stability. When the user pulls the handle 3500, the handle 3500 is not easy to loosen, and there will be no gap between the handle 3400 and the cover 3400, and it is integrated Stronger, which can improve the texture and appearance of the product.

Generally speaking, the oven door 3000 is in a vertical state in most cases, or in some pull-out ovens, the oven door 3000 is in a vertical state, and the window plate 3200 has a direction facing downward relative to the inner door 3100 . Therefore, the three-layer laminated structure formed by the support plate 3300 , the window plate 3200 and the cover 3400 effectively fixes the bottom of the window plate 3200 , thereby effectively enhancing the stability of the window plate 3200 .

Optionally, in some embodiments of the present application, as shown in FIG. 5 and FIG. 6 , the support plate 3300 has a portion protruding toward the inner door 3100 , specifically the top of the support plate 3300 , through which the top protrudes toward the inner door 3100 A certain distance is set, so that the clamping cavity 3600 is formed between the covering member 3400 and the thickness of the supporting plate 3300 and/or the covering member 3400 can be reduced, thereby reducing the weight of the oven door 3000 . It can be understood that since the cover 3400 is located on the outermost side of the oven door 3000 and occupies the main visual range of the user, when the support plate 3300 is protruded to form the clamping cavity 3600, the cover 3400 can be designed as a flat plate to avoid A part of the outer surface of the oven door body 3000 protrudes outward.

Optionally, as shown in FIG. 5 and FIG. 6 , in some embodiments of the present application, in order to facilitate effective fixing between the cover 3400 , the window plate 3200 and the support plate 3300 , the support plate 3300 , the window plate 3200 and the support plate 3300 The cover 3400 is respectively provided with fastening holes 3410. The oven door 3000 also includes fasteners. For example, the fasteners can be threaded fasteners, such as screws and bolts. The fasteners pass through the support plate 3300 and the window plate 3200. and the fastening hole 3410 of the cover 3400 to fix the three, and when the fastener passes through the window plate 3200, the fastener forms a constraint on the window plate 3200, effectively fixing the window plate 3200. By passing and fixing the fasteners, it is more convenient to combine the supporting board 3300, the window board 3200 and the covering member 3400 into a three-layer superimposed structure.

As shown in FIG. 3 , FIG. 5 and FIG. 6 , in some embodiments of the present application, the fastening hole 3410 is provided above the handle 3500 . A three-layer laminated structure is formed among the component 3400, the window plate 3200 and the support plate 3300, and the fastener is fixed to the bottom of the window plate 3200, so the position of the cover 3400 above the handle 3500 and near the bottom of the window plate 3200 When the user pulls the handle 3500 , there will be a gap between the handle 3500 and the window plate 3200 , or even a large deformation. Therefore, by setting the fastening hole 3410 above the handle 3500, that is, the fixing point of the cover 3400 is set above the handle 3500, so that when the user pulls the handle 3500, the cover 3400 is close to the bottom of the handle 3500 and the window panel 3200. There is no gap between the part and the window plate 3200, which improves the aesthetic appearance.

As shown in FIG. 4 and FIG. 5 , in some embodiments of the present application, the handle 3500 extends forward and downward, and is in a concave arc shape. The so-called concave arc shape is the shape seen by the user viewing the handle 3500 from top to bottom. Thus, the upper surface of the handle 3500 can form a concave surface 3510. As can be seen from the above, the handle 3500 and the cover 3400 are integrally formed. The intersection point is the center of rotation and has a tendency to turn upwards, so breakage is likely to occur between the handle 3500 and the cover 3400. For this reason, the upper surface of the handle 3500 is formed into a concave surface, so that there is no gap between the upper surface of the handle 3500 and the cover 3400. A smooth transition can be formed so that when the user pulls the handle 3500, stress concentration is not easily formed between the handle 3500 and the cover 3400, thereby reducing the risk of fracture.

It can be understood that the handle 3500 is set in a concave arc shape, so when the user observes from bottom to top, the lower surface of the handle 3500 can form a convex surface 3520, and when the user wants to pull the oven door 3000, the hand can move from bottom to top. Swing up to the handle 3500 and stick to the convex surface 3520, which is more in line with the grip of the hand and improves the hand feeling.

4, 5 and 7, in some embodiments of the present application, the cover 3400 is designed to constitute most of the front surface of the oven door 3000, so that the front surface of the oven door 3000 is more complete . Specifically, the cover 3400 is provided with a second through hole 3420, so that the outside of the window plate 3200 can abut against the cover 3400 to block the second through hole 3420, that is, the outside of the window plate 3200 abuts against the second through hole. A clamping cavity 3600 is formed between the peripheral part of the hole 3420 , the part below the second through hole 3420 and the support plate 3300 . That is to say, the cover 3400 not only blocks the support plate 3300, but also blocks the periphery of the window plate 3200, so that the cover 3400 can form the front surface of the oven door 3000, or form the vast majority of the front surface of the oven door 3000. In this way, the front surface of the oven door 3000 is more complete, avoiding the feeling of splitting, the integrated design is stronger, and the number of parts is reduced, thereby reducing the cost. When the window plate 3200 abuts against the peripheral portion of the second through hole 3420 , the cover member 3400 can protect the peripheral portion of the window plate 3200 .

When the cover 3400 is formed with the second through hole 3420, in order to fix the top of the cover 3400, optionally, in some embodiments, the oven door 3000 further includes a top cover 3700, and the top cover 3700 is fixed to the inner door 3100. top. For example, the top of the inner door 3100 extends forward, the top of the inner door 3100 is provided with fastening holes, the top cover 3700 covers the top of the inner door 3100, and the fasteners pass through the top of the top cover 3700 and the inner door 3100 so that the top The cover 3700 is fixed to the top of the inner door 3100 . The top cover 3700 is provided with a first flange 3710, and the first flange 3710 extends downward from the top cover 3700 for an end distance. 3700 is mounted on the top of the inner door 3100, the top cover 3700 and the top of the inner door 3100 are fixed to each other, and the first flange 3710 extends downward to abut against the top of the cover 3400, specifically the first flange 3710 and the cover 3400 The outer side of the part above the second through hole 3420 abuts against the outer side of the inner door 3100 to jointly clamp the top of the window panel 3200 , effectively realizing the fixation.

Optionally, as shown in FIG. 4 , in some embodiments of the present application, in order for the inner door 3100 to effectively support the window panel 3200 and reduce the number of components, the inner door 3100 is provided with a boss 3110 , and the boss 3110 faces inward The outer side of the door 3100 is protruded, and the middle of the boss 3110 forms a first through hole 3111. For example, when the inner door 3100 is processed with the first through hole 3111, the boss 3110 is punched out synchronously, and the boss 3110 abuts against the window plate On one side of the 3200, additional components are avoided to support the window panel 3200, reducing the number of components. In addition, by setting the boss 3110 on the inner door 3100 , the space between the support plate 3300 and the inner door 3100 can be increased to ensure that the oven door 3000 has a certain thickness.

The support plate 3300 is provided with a mounting column 3310, and the mounting column 3310 is arranged below the boss 3110, so that the space under the boss 3110 is fully utilized, and the inner door 3100 is connected with the mounting column 3310 by fasteners, thereby realizing the support plate 3300 And the fastening of inner door 3000.

Optionally, in some embodiments of the present application, as shown in FIG. 4 and FIG. 5 , the bottom of the inner door 3100 is further provided with a second flange 3120 , and the second flange 3120 extends forward so that it can support plate 3300 and the bottom of the cover 3400, thereby avoiding the formation of an opening of the oven door 3000.

The present application also discloses a combined cooker, which includes the oven door 3000 mentioned above. The structure of the oven door 3000 refers to the above-mentioned embodiments. Since the combination cooker adopts the technical solutions of the above-mentioned embodiments, it at least has the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not repeat them one by one again.

It can be understood that a combination stove is a combined kitchen appliance that combines two traditional independent appliances. For example, a combination stove may include a combined appliance that integrates a stove and an oven. The cooker includes the corresponding cooktop part, which can realize the cooking of ingredients with open flames or non-open flames. For example, cooking areas are set on the left and right sides of the combined cooker, and the cooking areas are equipped with electromagnetic heating devices or combustible gas. burner. The oven is located below the cooktop, and the oven includes the oven door 3000 in the above embodiment. The high temperature of the oven can be generated by electric heating or gas combustion. For example, when the cooker uses an open flame to cook ingredients, the corresponding oven can also use gas combustion to achieve heating; when the cooker uses electromagnetic heating, the corresponding oven can use electric heating.

1 and 2, and as shown in FIGS. 7 to 13, in some embodiments of the present application, the oven has a box body 1000, and the box body 1000 has an inlet and outlet 1100, regardless of the oven door 3000 relative to the box body 1000 No matter which method is used to close and open the inlet and outlet 1100 , it is necessary to ensure that the oven door 3000 forms a seal to the inlet and outlet 1100 when closing the inlet and outlet 1100 , so as to prevent the internal heat loss of the box body 1000 . It can be understood that when the oven is in a baking state, a large amount of heat is generated to cook the ingredients, so the effective sealing of the inlet and outlet 1100 can prevent heat loss through the inlet and outlet 1100 .

For this reason, effective sealing between the oven door 3000 and the box body 1000 is achieved by setting the first rib 4100 and the second rib 4200 . The first rib 4100 is arranged on one of the oven door body 3000 and the box body 1000, and when the oven door body 3000 closes the inlet and outlet 1100 of the box body 1000, the first rib 4100 abuts against the oven door body 3000 and the box body In the other one of 1000, the second rib 4200 is arranged on one of the oven door 3000 and the box body 1000, and when the oven door 3000 closes the inlet and outlet 1100 of the box body 1000, the second rib 4200 abuts against the The other of the oven door body 3000 and the box body 1000, and when the oven door body 3000 closes the inlet and outlet 1100, the first rib 4100 and the second rib 4200 are arranged at intervals and are radially spaced along the inlet and outlet 1100 arrangement to improve the sealing effect.

When the oven door 3000 closes the inlet and outlet 1100, the first rib 4100 and the second rib 4200 are between the box body 1000 and the oven door 3000 at the periphery of the inlet and outlet 1100, when the heat in the box 1000 When overflowing from the inlet and outlet 1100 to between the box body 1000 and the oven door 3000 , it will be blocked by the first rib 4100 and the second rib 4200 , so as to avoid the overflow of heat. It can be understood that the second rib 4200 and the first rib 4100 are located at the periphery of the inlet and outlet 1100 when the oven door 3000 closes the inlet and outlet 1100. The path through which the gap flow will pass, while the arrangement of the second rib 4200 and the first rib 4100 is located on the path of heat flow, blocking the flow of heat.

In addition, by setting the distance between the first rib 4100 and the second rib 4200 , the sealing contact area (contact area) can be increased, thereby enhancing the reliability of the sealing and preventing heat loss more effectively. For example, if only the first rib 4100 is provided, because the size of the inlet and outlet 1100 is relatively large, the span of the first rib 4100 should be large enough to surround the inlet and outlet 1100. If the first rib 4100 and the oven door 3000 If it abuts against the other of the box body 1000, higher requirements will be placed on the manufacturing process of the first rib 4100, the matching and precision of the oven door 3000 and the box body 1000, etc., because the first rib 4100 The span is large, and along the length direction of the first rib 4100, if the first rib 4100 is slightly deformed, the seal may fail. Therefore, by arranging the first rib 4100 and the second rib 4200 spaced apart from the first rib 4100, the probability of simultaneous deformation of the same part of the first rib 4100 and the second rib 4200 is greatly reduced, even if the first rib The 4100 seal fails and the second rib 4200 can still play a sealing role, thereby effectively reducing heat loss, and can also reduce process requirements for the production and preparation process of the product.

In addition, under the premise of ensuring the same contact area, if only the first rib 4100 is provided without the second rib 4200 , the first rib 4100 and the oven door 3000 will abut against the other of the box body 1000 A contact area of 2S is formed. If the first rib 4100 and the second rib 4200 are provided at the same time, the contact area formed by the first rib 4100 and the second rib 4200 abutting against the other of the oven door 3000 and the box body 1000 is also 2S, However, it can be allocated to the first rib 4100 and the second rib 4200, that is, the contact area formed by the first rib 4100 is S, the contact area formed by the second rib 4200 is S, and the total contact area remains unchanged, but The smaller area of the first rib 4100 and the second rib 4200 can better control the deformation, thereby forming multiple continuous sealing effects, making the sealing effect better and more reliable.

It can be understood that, through the arrangement of the first ribs 4100 and the second ribs 4200 at intervals along the radial direction of the inlet and outlet 1100, multiple continuous dense effects are achieved, where the radial direction is from the center of the inlet and outlet 1100 toward the inlet and outlet. 1100 , so that when the heat escapes from between the box body 1000 and the oven door 3000 , it can be blocked by the first rib 4100 and the second rib 4200 in turn.

Specifically, there are many ways to arrange the first rib 4100 and the second rib 4200:

For example, as shown in Figure 11, the first rib 4100 and the second rib 4200 are all arranged on the oven door 3000, and the box body 1000 is not provided with the first rib 4100 and the second rib 4200, and the box body 1000 forms Corresponding to the abutment plane, when the oven door 3000 closes the inlet and outlet 1100, the first rib 4100 and the second rib 4200 abut against the abutment plane of the box body 1000. It can be understood that the abutment of the box body 1000 The plane constitutes the peripheral portion of the entrance and exit 1100 .

It may also be that, as shown in FIG. 13 , both the first rib 4100 and the second rib 4200 are arranged on the box body 1000, and the oven door 3000 is not provided with the first rib 4100 and the second rib 4200, and the oven door The body 3000 forms a corresponding abutment plane. When the oven door 3000 closes the inlet and outlet 1100 , the first rib 4100 and the second rib 4200 abut against the abutment plane of the oven door 3000 .

It can also be, as shown in FIG. 12 , the first rib 4100 is arranged on the box body 1000, and the second rib 4200 is arranged on the oven door 3000. When the oven door 3000 closes the inlet and outlet 1100, the first rib 4100 abuts against the oven door 3000 , and the second rib 4200 abuts against the box body 1000 , so that the sealing of the inlet and outlet 1100 can also be realized.

By setting the first rib 4100 to the box body 1000 or the oven door body 3000, the second rib 4200 is set to the box body 1000 or the oven door body 3000, so that when the oven door body 3000 closes the inlet and outlet 1100 of the box body 1000 , the first rib 4100 and the second rib 4200 will be between the box body 1000 and the oven door 3000, and the first rib 4100 and the second rib 4200 will be located at the periphery of the inlet and outlet 1100 to form a seal for the inlet and outlet 1100 In addition, by arranging the first rib 4100 and the second rib 4200 at intervals, the sealing area can be increased, achieving the effect of continuous sealing and effectively preventing heat loss. It can be understood that no matter whether the first rib 4100 , the second rib 4200 or both are set on the oven door 3000 , they are all set on the inner door 3100 of the oven door 3000 hereinafter.

As shown in FIG. 14, in some embodiments of the present application, the first rib 4100 includes a straight section 4110 and a connecting section 4120. The opposite sides of the straight section 4110 are connecting sections 4120. When the oven door 3000 is closed When the first rib 4100 abuts against the other of the oven door 3000 and the box body 1000 at the entrance and exit 1100 , the first rib 4100 abuts through its straight section 4110 .

Specifically, taking the first rib 4100 disposed on the oven door 3000 as an example for illustration, the first rib 4100 disposed on the box body 1000 has a similar technical effect and will not be repeated here. The first rib 4100 protrudes toward the box body 1000 relative to the oven door body 3000, the connecting section 4120 is convex from the side of the oven door body 3000 facing the box body 1000, and the straight section 4110 is arranged on the two connecting sections Between 4120, the straight section 4110 is used to abut against the abutment plane of the box body 1000 (the part surrounding the periphery of the inlet and outlet 1100), that is to say, the cross section of the straight section 4110 extends in the vertical direction in the direction shown in Figure 14 , forming a flat plane as a whole, so that the contact with the box body 1000 can be effectively realized and a more effective sealing can be achieved.

Continuing to show in FIG. 14, in some embodiments of the present application, the second rib 4200 also includes a straight section 4210 and a connecting section 4220, and the opposite sides of the straight section 4210 are connecting sections 4220, when the oven door When 3000 closes the inlet and outlet 1100 and the second rib 4200 abuts against the other of the oven door 3000 and the box body 1000 , the second rib 4200 abuts through its straight section 4210 .

Specifically, it will be described by taking the second rib 4200 disposed on the oven door 3000 as an example. The second rib 4200 disposed on the box body 1000 has a similar technical effect and will not be repeated here. The second rib 4200 protrudes toward the box body 1000 relative to the oven door body 3000, the connecting section 4220 is convex from the side of the oven door body 3000 facing the box body 1000, and the straight section 4210 is arranged on the two connecting sections Between 4220, the straight section 4210 is used to abut against the abutment plane of the box body 1000 (the part surrounding the periphery of the inlet and outlet 1100), that is to say, the cross section of the straight section 4210 extends in the vertical direction in the orientation shown in Figure 14 , forming a flat plane as a whole, so that the contact with the box body 1000 can be effectively realized and a more effective sealing can be achieved.

Through the straight section 4110 of the first rib 4100 and the straight section 4210 of the second rib 4200 , the contact with the abutting plane of the box body 1000 can be effectively realized, thereby effectively improving the sealing effect and preventing heat loss.

Continuing to show in FIG. 14, in some embodiments of the present application, an arc transition is formed between the connecting section (4120/4220) and the straight section (4110/4210), so as to reduce stress concentration and prevent the connecting section (4120/4220 ) and a crack between the straight section (4110/4210).

Specifically, taking the first rib 4100 and the second rib 4200 arranged on the oven door 3000 as an example, when the oven door 3000 closes the inlet and outlet 1100, the oven door 3000 will place the first rib 4100 and the second rib 4200 is pressed against the abutment plane of the box body 1000, at this time the first rib 4100 and the second rib 4200 are subjected to a relatively large force, because the straight section (4110/4210) is close to the abutment with the box body 1000 as a whole The planes are parallel, while the connection section (4120/4220) is not parallel to the abutment plane of the box body 1000, so stress concentration is prone to occur at the intersection of the connection section (4120/4220) and the straight section (4110/4210), especially It is more prone to aging and fracture after long-term use, thereby reducing the sealing effect. Therefore, by setting the connection section (4120/4220) and the straight section (4110/4210) as an arc-shaped transition, that is to say, a circular arc angle is formed, so that the risk of cracking due to aging at this part can be avoided. In particular, the connecting section (4120/4220) can be arranged to be arc-shaped relative to the straight section (4110/4210), which can reduce the manufacturing difficulty of the first rib 4100 and the second rib 4200, especially When the first rib 4100 and the second rib 4200 are sheet metal parts formed by stamping.

As mentioned above, as long as it can ensure that the first rib 4100 and the second rib 4200 form continuous multiple seals, the first rib 4100 and the second rib 4200 can be arranged on the box body 1000 and the oven door Any one of 3000, optionally, in this embodiment, the second rib 4200 and the first rib 4100 are set to one of the oven door 3000 and the box 1000 at the same time, which can reduce manufacturing difficulty and Cooperate with requirements.

For example, as shown in FIG. 14 , taking the first rib 4100 and the second rib 4200 installed on the oven door 3000 as an example, the arrangement of the first rib 4100 and the second rib 4200 on the box body 1000 has a similar technical effect , not repeated. When both the first rib 4100 and the second rib 4200 are arranged on the oven door 3000 , it is only necessary to form an abutment plane on the box body 1000 to match the first rib 4100 and the second rib 4200 . If the first rib 4100 is set on the oven door 3000, and the second rib 4200 is set on the box body 1000, in this case the oven door 3000 needs to cooperate with the second rib 4200 to form an abutment plane, and the box body 1000 also needs to Cooperating with the first rib 4100 to form an abutment plane, the manufacturing process is more complicated.

In addition, it is more convenient to arrange the first rib 4100 and the second rib 4200 on the oven door 3000 than the first rib 4100 and the second rib 4200 on the box body 1000 . Specifically, the box body 1000 has a larger size because it needs to realize the baking and cooking of ingredients, while the oven door 3000 only needs to realize the closing and opening of the inlet and outlet 1100, and its size is smaller than that of the box body 1000, so It is also more convenient in processing. Especially, when both the box body 1000 and the oven door body 3000 are made of sheet metal parts, the first rib 4100 and the second rib 4200 are easier to be integrally formed on the oven door body 3000 .

Optionally, the first rib 4100 and the second rib 4200 can be prepared in various ways, for example, the first rib 4100 and the second rib 4200 are independently manufactured parts, and are connected to corresponding parts by some connecting means. The box body 1000 or the oven door body 3000 is, for example, bonded, welded, screwed, etc. Optionally, in some embodiments of the present application, the first rib 4100 and the second rib 4200 are integrally formed. For example, the first rib 4100 and the second rib 4200 are arranged on the oven door 3000, and the first rib 4100 and the second rib 4200 are formed by stamping, specifically, the inner door 3100 can be directly stamped to form the first rib. The first rib 4100 and the second rib 4200 have high structural strength and do not need to use additional connecting parts to realize the connection between the first rib 4100 and the second rib 4200 and the oven door 3000 , making the manufacture more convenient. Of course, in addition to the integral molding of the first rib 4100 and the second rib 4200 by stamping, the inner door 3100 , the first rib 4100 and the second rib 4200 can also be integrally prepared by using a mold.

As shown in FIG. 14 , in some embodiments, in order to strengthen the structural strength between the first rib 4100 and the second rib 4200 , a convex arc portion 4300 is formed between the second rib 4200 and the first rib 4100 .

For example, when the first rib 4100 and the second rib 4200 are arranged on the oven door 3000, the convex arc 4300 protrudes toward the inside of the oven door 3000, that is, the convex arc 4300 protrudes into the oven door in a direction away from the entrance and exit 1100. In 3000, it can be understood that when the first rib 4100 and the second rib 4200 are arranged on the oven door 3000, if the part between the first rib 4100 and the second rib 4200 is planar, the The ribs 4100 and the second ribs 4200 may be deformed when stressed, so they are designed in a convex arc shape and protrude toward the inside of the oven door 3000, so as to strengthen the structural strength. In addition, due to the formation of the convex arc portion 4300 , the space between the second rib 4200 and the first rib 4100 is increased, thereby reducing heat transfer.

When the first rib 4100 and the second rib 4200 are arranged on the box body 1000 (not shown in the figure), the convex arc part 4300 is protruded toward the inside of the box body 1000, and the technical effect is consistent with that when it is installed on the oven door 3000 , will not be repeated here.

Optionally, in some embodiments, as shown in FIG. 1 and FIG. 2 , a baking chamber 2000 is provided in the box body 1000, and the baking chamber 2000 is a structure for placing ingredients, and the baking chamber 2000 is configured to be able to Move in and out of the inlet and outlet 1100 along a straight line. For example, a slide rail is provided in the box body 1000, and the baking chamber 2000 is fixed on the slide rail. The oven door 3000 is fixed on the front end of the baking chamber 2000, so that when the user pulls the oven door 3000, the baking chamber 2000 can be moved out of the entrance and exit 1100, and when the user pushes the oven door 3000, the baking chamber 2000 can be moved into The entrance and exit are 1100 meters, which is convenient for users to take and place ingredients.

At this time, the first convex rib 4100 is designed as an inverted U-shaped structure, so that it is located on the upper side, left side and right side of the inlet and outlet 1100. Since the oven door 3000 needs to be fixedly connected with the baking chamber 2000, the heat mainly comes from the inlet and outlet. The upper side, the left side and the right side of 1100 are dissipated, so the first rib 4100 of the inverted U-shaped structure can realize effective sealing.

Correspondingly, the second rib 4200 also forms an inverted U-shaped structure so that when the oven door 3000 closes the inlet and outlet 1100, it can surround the first rib 4100 and be located on the outside of the first rib 4100, that is, the outer side is farther away from the inlet and outlet. 1100 direction for a more effective seal. Of course, in other embodiments, since most of the heat will flow from bottom to top with the steam, more heat will be concentrated on the upper side of the inlet and outlet 1100, so the second rib 4200 may not be set as an inverted U type, but only linearly located on the upper side of the inlet and outlet 1100 and above the first rib 4100 .

The above is only the preferred embodiment of the application, and does not limit the patent scope of the application. Under the conception of the application, the equivalent structural transformation made by using the specification and drawings of the application, or directly/indirectly used in Other relevant technical fields are included in the scope of patent protection of this application.
