Description

Technical Field

[0001] This utility model relates to the field of cooking device technology, and in particular to a cooking device that is easy to assemble. Background Technology

[0002] The cooking body of existing cooking devices is usually formed by an outer shell and an insulated inner liner. Since the cooking cavity is formed by the insulated inner liner, in order to reduce the heat loss inside the cooking cavity surrounded by the insulated inner liner and cause the outer shell to overheat, the insulated inner liner is placed inside the outer shell, and a certain gap is formed between the outer shell and the insulated inner liner. This gap can also be used for wiring or assembling other components.

[0003] However, the heat-insulating inner liner of existing cooking devices needs to form a cooking cavity, and the cooking cavity needs to have an opening for cooking utensils or food to be put in and out. Therefore, the heat-insulating inner liner adopts an assembly structure, which mainly consists of two side plates, a top plate and a bottom plate. During assembly, it is assembled with a screw structure, and then a sealing adjustment structure is set at the assembly gap. This results in a large number of parts to be processed and a complicated assembly process. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a cooking device that is easy to assemble. Its heat-insulating inner liner can be directly formed into a cooking chamber by a connection structure of a first heat-insulating shell and a second heat-insulating shell, and the assembly is simple.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A cooking device that is easy to assemble includes a cooking body with an insulated inner liner. The insulated inner liner includes a first insulated shell and a second insulated shell. The first insulated shell includes an integrally formed top plate segment and two side plate segments, with the two side plate segments connected to both sides of the top plate segment. The second insulated shell includes an integrally formed bottom plate segment and a back plate segment. The two sides of the bottom plate segment are connected to the bottom ends of the two side plate segments, and the bottom plate segment is connected to the bottom end of the back plate segment. The two sides of the back plate segment are connected between the two side plate segments, and the top end of the back plate segment is connected to the top plate segment.

[0007] Furthermore, the two side plate segments are integrally formed onto the top plate segment using a bending process.

[0008] Furthermore, the bottom plate segment is integrally formed at the bottom end of the back plate segment using a bending process.

[0009] Furthermore, the top plate segment and the side plate segment are each provided with a first snap-fit ​​part, and the back plate segment is provided with a second snap-fit ​​part, which is snap-fitted and connected to the first snap-fit ​​part.

[0010] Furthermore, the first latching portion includes a latching tab, and the second latching portion includes a card interface; the latching tab latches onto the card interface.

[0011] Furthermore, the snap-fit ​​tab includes a snap-fit ​​arm and a snap-fit ​​segment, the snap-fit ​​segment being connected to the end of the snap-fit ​​arm; the end wall of the snap-fit ​​segment away from the snap-fit ​​arm is provided with a guide slope.

[0012] Furthermore, the end of the latching segment near the latching segment is provided with a clearance slope.

[0013] Furthermore, the bottom end of the side plate segment is provided with the first snap-fit ​​portion; the bottom plate segment is provided with the second snap-fit ​​portion.

[0014] Furthermore, the back plate section is provided with a flange that bends toward the first heat insulation shell.

[0015] Furthermore, the side panel section is provided with an outwardly extending connecting edge; the connecting edge is provided with a plurality of first connecting holes; the cooking appliance body is provided with a plurality of second connecting holes, the plurality of second connecting holes corresponding to the plurality of first connecting holes, and connecting parts passing through them.

[0016] In summary, this utility model has the following technical effects:

[0017] Because the two side plate sections and the top plate section are integrally formed during assembly, the assembly between the top plate section and the side plate sections can be reduced. Therefore, there is no assembly gap between the side plate sections and the top plate section at the top, meaning there is no assembly gap on either side of the top of the cooking chamber, resulting in a good sealing effect. Similarly, the bottom plate section and the back plate section are also integrally formed, eliminating the need for separate assembly between the back plate section and the bottom plate section. After the first and second heat insulation shells are assembled, the assembly gaps only exist at the connection points between the back plate section, the bottom plate section, and the side plate sections, i.e., the bottom and back surfaces of the cooking chamber. Only the bottom and back surfaces need to be sealed; the top surface does not require separate sealing, reducing the need for sealing structures and simplifying the assembly structure.

Detailed Implementation

[0026] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] See Figures 1-6This utility model discloses a cooking device that is easy to assemble, including a cooking body 10. The cooking body 10 has a heat-insulating inner liner 30. Specifically, the heat-insulating inner liner 30 includes a first heat-insulating shell 31 and a second heat-insulating shell 32. The first heat-insulating shell 31 includes a top plate section 311 and two side plate sections 312. The two side plate sections 312 are integrally formed with the top plate section 311, and are connected to both sides of the top plate section 311. The second heat-insulating shell 32 includes a bottom plate section 321 and a back plate section 322. Similarly, the bottom plate section 321 and the back plate section 322 are integrally formed, and the bottom plate section 321 is connected to the bottom end of the back plate section 322.

[0030] When assembling the first heat insulation shell 31 and the second heat insulation shell 32, the two sides of the bottom plate section 321 are connected to the bottom ends of the two side plate sections 312, the two sides of the back plate section 322 are connected between the two side plate sections 312, and the top end of the back plate section 322 is connected to the top plate section 311. After assembly, since the back plate section 322 is closed on the back of the two side plate sections 312 of the first heat insulation shell 31, and the bottom plate section 321 is closed on the bottom surface of the two side plate sections 312 of the first heat insulation shell 31, a cooking chamber with an opening can be formed.

[0031] Because the two side plate segments 312 and the two sides of the top plate segment 311 are integrally formed during the assembly process, the assembly between the top plate segment 311 and the side plate segment 312 can be reduced. Therefore, there is no assembly gap between the side plate segment 312 and the top plate segment 311 at the top, meaning that there is no assembly gap on both sides of the top of the cooking chamber, resulting in a good sealing effect. Similarly, the bottom plate segment 321 and the back plate segment 322 are also integrally formed, eliminating the need for separate assembly between the back plate segment 322 and the bottom plate segment 321. After the first heat insulation shell 31 and the second heat insulation shell 32 are assembled, the assembly gap only exists at the connection positions of the back plate segment 322, the bottom plate segment 321, and the side plate segment 312, i.e., the bottom and back surfaces of the cooking chamber. Only the bottom and back surfaces need to be sealed, and the top surface does not need to be sealed separately, reducing the need for sealing structures and simplifying the assembly structure.

[0032] It should also be noted that during cooking, steam or grease typically rises to the top surface. Since this application eliminates the need for additional sealing structures in the top plate section 311 and side plate section 312, it reduces the possibility of steam or grease overflowing due to sealing structure failure or aging. Furthermore, it prevents contamination from rising steam or grease caused by additional sealing structures, facilitating cleaning.

[0033] Of course, after the heat-insulating inner liner 30 is assembled into the cooking body 10, a heating tube 41 and a fan blade 42 can be installed at the top of the cooking chamber, and a motor 43 for driving the fan blade 42 can be installed at the top of the top plate section 311. In this way, the heating tube 41 heats the cooking chamber, and the motor 43 drives the fan blade 42 to rotate to realize heat flow and achieve cooking. The heating method of the cooking chamber is not limited to the one in this embodiment. It can also be that the heating structure is installed at the bottom of the cooking chamber, or the heating structure is installed on the side or back plate of the cooking chamber. In short, any structure that can realize the structure of the cooking chamber is acceptable, which will not be described in detail here.

[0034] Furthermore, in this embodiment, the two side plate segments 312 are integrally formed on the top plate segment 311 by a bending process, and similarly, the bottom plate segment 321 is integrally formed on the bottom end of the back plate segment 322 by a bending process. That is, the first heat insulation shell 31 and the second heat insulation shell 32 can be made of existing sheet metal materials, and then integrally formed by sheet metal bending process. After forming, a heat insulation coating (such as PTFE coating, ceramic coating, PESU coating, etc. in the prior art) can be applied to the first heat insulation shell 31 and the second heat insulation shell 32. This process is simple and the cost is low.

[0035] Furthermore, in this embodiment, for ease of assembly, a first snap-fit ​​portion can be provided on both the top plate segment 311 and the side plate segment 312, and a second snap-fit ​​portion can be provided on the back plate segment 322, with the second snap-fit ​​portion engaging with the first snap-fit ​​portion. Thus, when assembling the top plate segment 311 and the back plate segment 322, the first snap-fit ​​portion on the top plate segment 311 can be snap-fitted with the second snap-fit ​​portion at the top of the back plate segment 322. The side plate segment 312 is snap-fitted with the side of the back plate segment 322, making assembly convenient.

[0036] Of course, the first snap-fit ​​part and the second snap-fit ​​part can be directly integrally formed on the first heat insulation shell 31 and the second heat insulation shell 32, so that there is no need to set up screws, bolts and other structures for connection, reducing the use of parts.

[0037] Furthermore, the first snap-fit ​​part includes a snap-fit ​​piece 313, and the second snap-fit ​​part includes a snap-fit ​​interface 323. The snap-fit ​​piece 313 snaps into the snap-fit ​​interface 323, that is, during assembly, the snap-fit ​​connection is achieved by inserting the snap-fit ​​piece 313 into the snap-fit ​​interface 323.

[0038] Specifically, the aforementioned snap-fit ​​piece 313 includes a snap-fit ​​arm 3131 and a snap-fit ​​section 3132. The snap-fit ​​section 3132 is connected to the end of the snap-fit ​​arm 3131, and the end wall of the snap-fit ​​section 3132 away from the snap-fit ​​arm 3131 is provided with a guide slope 3133. Thus, the snap-fit ​​segment 3132 can be connected to the top plate segment 311 and the side plate segment 312 via the snap-fit ​​arm 3131. The width of the snap-fit ​​segment 3132 can be greater than the width of the snap-fit ​​arm 3131. After the snap-fit ​​segment is connected to the snap-fit ​​arm 3131, a connection gap can be formed between the snap-fit ​​arm 3131 and the top plate segment 311 and the side plate segment 312. During the process of the snap-fit ​​segment 3132 snapping into the card interface 323, the snap-fit ​​segment 3132 is guided smoothly into the card interface 323 by the guide slope 3133, and then the snap-fit ​​piece 313 is bent downward. The presence of the snap-fit ​​segment 3132 can prevent the surface of the back plate segment 322 from being scratched during the downward bending process of the snap-fit ​​segment 3132.

[0039] Furthermore, the snap-fit ​​section 3132 is provided with a relief slope 3134 at one end near the snap-fit ​​section 3132. The relief slope 3134 can better avoid the surface of the back plate section 322 during the snap-fit ​​process of the snap-fit ​​section 3132 bending and snapping, thereby reducing scratches during the assembly process.

[0040] Similarly, a first snap-fit ​​part is provided at the bottom end of the side plate section 312; a second snap-fit ​​part is provided in the bottom plate section 321. That is, the assembly connection between the bottom plate section 321 and the side plate section 312 can also be achieved by using the snap-fit ​​method of the first snap-fit ​​part and the second snap-fit ​​part, which is convenient for assembly and reduces the use of bolts, screws and other connection structures.

[0041] Furthermore, the back plate section 322 is provided with a flange that bends toward the first heat insulation shell 31. After the back plate section 322 is assembled with the top plate section 311 and the side plate section 312, the flange can cover the assembly gap and improve the assembly sealing.

[0042] Furthermore, the side panel section 312 can be provided with an outwardly extending connecting edge, and the connecting edge is provided with a plurality of first connecting holes. In addition, a plurality of second connecting holes are provided inside the cooking body 10, and the plurality of second connecting holes correspond to the plurality of first connecting holes. Thus, when assembling the heat-insulating inner liner 30 with the cooking body 10, the plurality of first connecting holes on the connecting edge of the side panel section 312 can be aligned with the plurality of second connecting holes of the cooking body 10, and connecting parts can be inserted through the first connecting holes and the second connecting holes to achieve the assembly of the heat-insulating inner liner 30 with the cooking body 10 using connecting parts (such as screws, pins, bolts, etc.).

[0043] It should be noted that the connecting edge extending from the side plate segment 312 is used as the base surface for assembly with the cooking body 10, which can improve the connection and assembly surface, stabilize the assembly structure, and provide a first connecting hole on the connecting edge that corresponds to the second connecting hole on the cooking body 10, which facilitates alignment and assembly and reduces assembly difficulty.

[0044] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
