Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to a cavity structure and a cooking appliance. BACKGROUND

[0002] With the development of technology, people have higher and higher requirements for the cooking appliance used. The cavity structure of the cooking appliance should not only be easy to clean, but also should not affect the appearance by gluing, and should also ensure that there is no water leakage or air leakage.

[0003] In the related art, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the back plate 104' in the cavity structure 100' is located at the rear side of the bottom plate 102', the cover 106' is connected to the back plate 104', and the connecting surface of the back plate 104' and the bottom plate 102' is vertically arranged. During use, the connecting part of the back plate 104' and the bottom plate 102' (i.e. Q at the arrow in Figure 3 and Figure 4 ) is prone to liquid leakage. In addition, this position needs to be glued, which affects the appearance of the cavity structure. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art.

[0005] To this end, the first aspect of the present application provides a cavity structure.

[0006] The second aspect of the present application provides a cooking appliance.

[0007] The first aspect of the present application provides a cavity structure, comprising: a surrounding plate assembly, the surrounding plate assembly comprising a first opening and a bottom plate; a back plate arranged at the first opening and connected to the surrounding plate assembly, the back plate comprising a protruding portion, the protruding portion protruding into the interior of the surrounding plate assembly from the first opening and at least contacting the bottom plate.

[0008] The cavity structure provided by the present application comprises a surrounding plate assembly and a back plate. The surrounding plate assembly comprises a first opening and a bottom plate, the back plate is arranged at the position of the first opening and connected to the surrounding plate assembly, thereby sealing the first opening by the back plate. In this way, the cooking cavity is defined by the surrounding plate assembly and the back plate, and the food to be cooked is placed in the cooking cavity during use of the cavity structure.

[0009] Further, in the cavity structure provided by the present application, the back plate comprises a protruding portion, and the protruding portion protrudes towards the side of the surrounding plate assembly. In this way, after the cavity structure is assembled, the protruding portion of the back plate can be embedded in the interior of the surrounding plate assembly, and the protruding portion at least contacts the bottom plate.

[0010] In particular, the protruding portion of the back plate can be embedded in the inner part of the surrounding plate assembly, and the protruding portion is at least in contact with the bottom plate of the surrounding plate assembly. In this way, by the setting of the protruding portion of the back plate at the bottom of the cavity assembly, the contact area between the back plate and the bottom plate can be increased, in particular, a certain length of the contact surface in the transverse direction can be increased, and thus the sealing effect between the back plate and the bottom plate can be effectively improved. When the cavity structure is applied to a cooking appliance, the possibility of water seepage between the back plate and the bottom plate of the surrounding plate assembly can be significantly reduced, and thus the liquid in the cooking cavity can be prevented from overflowing.

[0011] Further, since the protruding portion of the back plate is embedded in the inner part of the surrounding plate assembly, the contact area between the back plate and the surrounding plate assembly is increased, and the back plate can be directly limited by the cooperation between the protruding portion and the surrounding plate assembly. In this way, the connection firmness of the back plate and the surrounding plate assembly can be significantly improved, and thus the connection between the back plate and the surrounding plate assembly can be avoided, and the possibility that the appearance of the cavity structure is affected by the gluing process can be avoided.

[0012] In some possible designs, the back plate comprises a first pressing structure, and the first pressing structure forms the protruding portion.

[0013] In this design, the cavity structure provided by the present application can directly manufacture the protruding portion by a stamping process. Specifically, during the manufacturing of the back plate, the back plate can be subjected to stamping treatment, and thus a first pressing structure is formed on the back plate. The first pressing structure protrudes towards the side of the surrounding plate assembly, and thus the protruding portion is directly defined by the first pressing structure. In addition, the protruding portion is defined by the first pressing structure, which can also simplify the manufacturing process of the back plate, and thus the manufacturing efficiency of the back plate and the entire cavity structure.

[0014] In some possible designs, the bottom plate comprises a plate body, and a first boss protruding from the plate body of the bottom plate, and the protruding portion is lapped on the first boss.

[0015] In this design, the bottom plate comprises a plate body and a first boss. The first boss is arranged on the plate body, and the first boss protrudes from the plate body; after the cavity structure is assembled, the protruding portion of the back plate is lapped on the first boss. In particular, the first boss protrudes from the plate body, and the first boss supports the protruding portion of the back plate to a certain height, so that there is a certain height difference between the protruding portion of the back plate and the plate body.

[0016] In this way, during the use of the cavity structure, since the first boss supports the protruding portion of the back plate to a certain height, the contact surface between the first boss and the protruding portion has a certain height, and the liquid in the cooking cavity falls on the plate body under the action of gravity, and thus the possibility of liquid leakage in the cooking cavity is further reduced.

[0017] In addition, due to the arrangement of the first protrusion, the user can clean the cooking cavity more conveniently. Specifically, when the user wipes the bottom plate of the cooking cavity, the contact surface between the first protrusion and the convex portion has a certain height, so that the user can clean the impurities left on the bottom plate without bringing the impurities into the contact surface between the first protrusion and the convex portion, and the user can clean more conveniently.

[0018] In some possible designs, the bottom plate further comprises a second press structure, and the first protrusion is formed by the second press structure.

[0019] In this design, the bottom plate further comprises a second press structure, and the first protrusion is directly defined by the second press structure. In the process of manufacturing the bottom plate, the bottom plate can be subjected to a stamping process to form the second press structure on the bottom plate. The second press structure protrudes from the plate body of the bottom plate to directly define the first protrusion. In addition, the first protrusion is defined by the second press structure, which can simplify the manufacturing process of the bottom plate, and thus improve the manufacturing efficiency of the bottom plate and the entire cavity structure.

[0020] Specifically, the plate body is the part of the bottom plate that is not subjected to stamping.

[0021] In some possible designs, the contact surface between the convex portion and the first protrusion is higher than the plate body.

[0022] In this design, the contact surface between the convex portion and the first protrusion is higher than the plate body. That is, the first protrusion supports the convex portion of the back plate to a certain height, so that there is a certain height difference between the contact surface between the convex portion and the first protrusion and the plate body of the bottom plate. In this way, the liquid in the cooking cavity can drip onto the plate body of the bottom plate under the action of gravity, further reducing the possibility of liquid leakage in the cooking cavity.

[0023] In some possible designs, the contact surface between the convex portion and the first protrusion is transversely arranged.

[0024] In this design, the contact surface between the convex portion and the first protrusion is transversely arranged. In this way, the sealing effect between the back plate and the bottom plate of the surrounding plate assembly can be improved obviously. Specifically, the transverse arrangement of the contact surface between the convex portion and the first protrusion ensures that the dripping liquid cannot drip onto the contact surface between the convex portion and the first protrusion, and the arrangement of the contact surface between the convex portion and the first protrusion higher than the plate body ensures that the liquid dripping onto the plate body cannot flow to the contact surface between the convex portion and the first protrusion, thereby improving the sealing performance of the cavity structure.

[0025] In some possible designs, the bottom plate further comprises: an arc transition portion, and the plate body and the first protrusion are connected by the arc transition portion.

[0026] In the design, the bottom plate further comprises a circular arc transition part. The plate body and the first boss are connected through the circular arc transition part. In this way, the circular arc transition part can play a good transition effect between the plate body and the first boss, avoiding a right angle or a sharp point between the plate body and the first boss.

[0027] In the process of cleaning the cavity structure by the user, due to the setting of the circular arc transition part, the connection position of the plate body and the first boss is convenient to clean, so that impurities in the cavity structure will not remain at the connection position of the plate body and the first boss, which is convenient for the user to operate and is also conducive to the cleaning of the cavity structure.

[0028] In some possible designs, the bottom plate further comprises: a second boss protruding from the plate body, and the first side plate is lapped on the second boss.

[0029] In the design, the bottom plate comprises a second boss. The second boss is arranged on the plate body of the bottom plate, and the second boss protrudes from the plate body of the bottom plate; after the cavity structure is assembled, the first side plate is lapped on the second boss. In this way, the second boss supports the first side plate to a certain height, so that the second boss has a certain height at the connection position of the first side plate, thereby avoiding the liquid in the cavity structure from overflowing from the connection position of the first side plate, and further reducing the possibility of liquid leakage in the cooking cavity.

[0030] In some possible designs, the bottom plate comprises: a third boss protruding from the plate body, and the second side plate is lapped on the third boss.

[0031] In the design, the bottom plate comprises a third boss. The third boss is arranged on the plate body of the bottom plate, and the third boss protrudes from the plate body of the bottom plate; after the cavity structure is assembled, the second side plate is lapped on the third boss. In this way, the third boss supports the second side plate to a certain height, so that the third boss has a certain height at the connection position of the second side plate, thereby avoiding the liquid in the cavity structure from overflowing from the connection position of the second side plate, and further reducing the possibility of liquid leakage in the cooking cavity.

[0032] In some possible designs, the surrounding plate assembly further comprises: a first side plate connected to the first side of the bottom plate and the back plate; a second side plate connected to the second side of the bottom plate and the back plate, the first side plate being arranged opposite to the first side plate; and a top plate connected to the first side plate, the second side plate and the back plate.

[0033] In the design, the enclosure assembly further comprises a first side plate, a second side plate and a top plate. The first side plate is connected to the first side of the bottom plate, and the second side plate is connected to the second side of the bottom plate. The first side plate and the second side plate are arranged oppositely, so that one of the first side plate and the second side plate is used as a left side plate, and the other is used as a right side plate. In addition, the top plate is connected to the top of the first side plate and the second side plate. Furthermore, the back plate is connected to the top plate, the first side plate, the second side plate and the top plate to ensure the stability of the entire cavity structure.

[0034] In some possible designs, the back plate further comprises a first connecting edge, and the first connecting edge is located at the circumferential side of the convex part and connected to the enclosure assembly.

[0035] In the design, the back plate comprises a first connecting edge. The first connecting edge is located at the circumferential side of the convex part, and the back plate is connected to the enclosure assembly through the connecting edge to ensure the stable connection of the back plate.

[0036] In some possible designs, the enclosure assembly comprises a flange structure, and the first connecting edge is connected to the flange structure. The connection position of the first connecting edge and the flange structure is located outside the enclosure assembly.

[0037] In the design, the enclosure assembly comprises a flange structure. The flange structure is arranged at the edge of the enclosure assembly, and specifically at the position of the first opening of the enclosure assembly. In addition, in the process of assembling the cavity structure, the flange structure of the enclosure assembly is connected to the first connecting edge of the back plate. Moreover, the connection position of the first connecting edge and the flange structure is located outside the enclosure assembly to facilitate the operation of the staff.

[0038] In some possible designs, the flange structure is vertically arranged.

[0039] In the design, the flange structure is vertically arranged. Correspondingly, the first connecting edge is also vertically arranged. In this way, in the process of connecting the back plate by the staff, the staff can operate horizontally, which is more in line with the operation habit of the staff and facilitates the operation of the user.

[0040] In some possible designs, the first connecting surface between the first connecting edge and the flange structure is vertically arranged.

[0041] In the design, the first connecting surface between the first connecting edge and the flange structure is vertically arranged. That is, in the process of connecting the first connecting edge and the flange structure by the user, the user can operate horizontally. Specifically, when the user uses a fastener to connect the first connecting edge and the flange structure, the user can directly pass the fastener horizontally through the first connecting edge and the flange structure, which is more convenient to operate.

[0042] In some possible design, the flanging structure is located on the top plate, the bottom plate, the first side plate and the second side plate; and the first connecting edge is located around the convex portion.

[0043] In this design, the flanging structure is located on the top plate, the bottom plate, the first side plate and the second side plate, and the first connecting edge is arranged around the convex portion. In this way, after the cavity structure is assembled, the flanging structure is connected with the first connecting edge, so that the four edges of the back plate are connected with the surrounding plate assembly, which improves the connection strength of the back plate and the surrounding plate assembly, and also improves the sealing performance of the connection position of the back plate and the surrounding plate assembly.

[0044] In some possible design, the cavity structure further comprises: a cover body, the cover body is arranged on the back plate; and a fan cavity, the fan cavity is located between the back plate and the cover body.

[0045] In this design, the cavity structure further comprises the cover body and the fan cavity. The cover body is arranged on the back plate, and the back plate is located between the surrounding plate assembly and the cover body. In addition, the cover body and the back plate have a space therebetween, and the fan cavity is defined by the space.

[0046] Specifically, when the cavity structure is applied to a cooking utensil, the fan cavity is used to place a hot air fan of the cooking utensil.

[0047] In some possible design, the cover body comprises a second connecting edge, the second connecting edge is connected with the first connecting edge and the flanging structure, and a second connecting surface between the first connecting edge and the second connecting edge is arranged vertically.

[0048] In this design, the cover body comprises the second connecting edge. The second connecting edge is connected with the first connecting edge and the flanging structure, so as to connect the cover body, the back plate and the surrounding plate assembly as a whole.

[0049] In addition, the second connecting surface between the first connecting edge and the second connecting edge is arranged vertically. That is, the user can operate horizontally in the process of connecting the first connecting edge and the flanging structure. Specifically, when the user installs the cover body by using fasteners, the fasteners can be directly inserted horizontally through the second connecting edge, the first connecting edge and the flanging structure, and the operation is more convenient.

[0050] Specifically, the second connecting edge is located around the cover body, and the shape of the second connecting edge matches the shape of the first connecting edge of the back plate. In this way, the four edges of the cover body are connected with the back plate, which improves the connection strength of the cover body and the back plate, and also improves the sealing performance of the connection position of the cover body and the back plate.

DETAILED DESCRIPTION

[0076] In order to enable a more clear understanding of the above-mentioned objects, features and advantages of the present application, the present application will be further described below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0077] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, and therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0078] The cavity structure 100 and the cooking appliance according to some embodiments of the present application will be described below with reference to Figures 5 to 14 .​​

[0079] As shown in Figure 5 , Figure 10 and Figure 11 , the first embodiment of the present application proposes a cavity structure 100, which comprises a surrounding plate assembly 102 and a back plate 104.

[0080] Wherein, as shown in Figure 5 , Figure 6 , Figure 7 and Figure 9 , the surrounding plate assembly 102 comprises a first opening and a bottom plate 108, and the back plate 104 is arranged at the position of the first opening and connected with the surrounding plate assembly 102, so as to seal the first opening through the back plate 104. In this way, the cooking cavity 144 can be defined by the surrounding plate assembly 102 and the back plate 104, and the food to be cooked can be placed in the cooking cavity 144 during the use of the cavity structure 100.

[0081] Further, as shown in Figure 12 , Figure 13 and Figure 14 , in the cavity structure 100 proposed by the present application, the back plate 104 comprises a protruding portion 106, and the protruding portion 106 protrudes towards the side of the surrounding plate assembly 102. In this way, after the cavity structure 100 is assembled, the protruding portion 106 of the back plate 104 can be embedded in the interior of the surrounding plate assembly 102, and the protruding portion 106 is at least in contact with the bottom plate 108 of the surrounding plate assembly 102.

[0082] In particular, as shown in Figure 12 , Figure 13 and Figure 14 , the protruding portion 106 of the back plate 104 can be embedded in the interior of the surrounding plate assembly 102, and the protruding portion 106 is at least in contact with the bottom plate 108 of the surrounding plate assembly 102. In this way, at the bottom of the cavity assembly, the protruding portion 106 of the back plate 104 can increase the contact area between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, in particular, a transversely extending contact surface 120 can be formed, thereby effectively improving the sealing effect between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102. When the cavity structure 100 is applied to a cooking appliance, the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102 can be significantly reduced, thereby avoiding the overflow of liquid in the cooking cavity 144.

[0083] Further, as shown in Figure 12 , Figure 13 and Figure 14As shown, due to the convex part 106 of the back plate 104 embedded into the inside of the enclosure assembly 102, the contact area between the back plate 104 and the enclosure assembly 102 is improved, and the back plate 104 can be directly limited by the cooperation of the convex part 106 and the enclosure assembly 102. In this way, the connection firmness of the back plate 104 and the enclosure assembly 102 can be obviously improved, and the gluing process can be avoided, thereby avoiding the possibility of affecting the appearance of the cavity structure 100 due to the gluing process.

[0084] The second embodiment of the present application proposes a cavity structure 100, which is further based on the first embodiment:

[0085] As shown in Figure 12 , Figure 13 and Figure 14 , in the cavity structure 100 proposed in this embodiment, the convex part 106 can be directly manufactured by a stamping process. Specifically, during the manufacturing of the back plate 104, the back plate 104 can be subjected to stamping treatment, thereby forming a first profiling structure on the back plate 104. The first profiling structure protrudes towards the side of the enclosure assembly 102, thereby directly defining the convex part 106 by the first profiling structure. In addition, the convex part 106 is defined by the first profiling structure, which can also simplify the manufacturing process of the back plate 104, thereby improving the manufacturing efficiency of the back plate 104 and the entire cavity structure 100.

[0086] In addition, the cavity structure 100 proposed in this embodiment has all the beneficial effects of the cavity structure 100 of the first embodiment, which can reduce the possibility of water seepage between the back plate 104 and the bottom plate 108 of the enclosure assembly 102, and can avoid gluing at the connection between the back plate 104 and the enclosure assembly 102, thereby avoiding the possibility of affecting the appearance of the cavity structure due to the gluing process. Here, it will not be discussed in detail.

[0087] The third embodiment of the present application proposes a cavity structure 100, which is further based on the first embodiment and the second embodiment:

[0088] As shown in Figure 6 and Figure 8 , the bottom plate 108 includes a first boss 110 and a plate body 118. The back plate 104 is connected to the bottom plate 108. In addition, the first boss 110 is arranged on the plate body 118 of the bottom plate 108, and the first boss 110 protrudes from the plate body 118 of the bottom plate 108; after the cavity structure 100 is assembled, the convex part 106 of the back plate 104 is overlapped on the first boss 110.

[0089] In particular, as shown in Figure 8As shown, the first boss 110 protrudes from the plate body 118 of the bottom plate 108, and the convex portion 106 of the back plate 104 is supported by the first boss 110 to a certain height, so that there is a certain height difference between the convex portion 106 of the back plate 104 and the plate body 118 of the bottom plate 108.

[0090] In this way, during use of the cavity structure 100, due to the first boss 110 supporting the convex portion 106 of the back plate 104 to a certain height, the contact surface 120 between the first boss 110 and the convex portion 106 has a certain height, and the liquid in the cooking cavity 144 falls to the plate body 118 of the bottom plate 108 under the action of gravity, further reducing the possibility of liquid leakage in the cooking cavity 144.

[0091] In addition, as shown in Figure 12 and Figure 13 Due to the arrangement of the first boss 110, it is more convenient for the user to clean the cooking cavity 144. Specifically, when the user wipes the bottom plate of the cooking cavity 144, due to the contact surface 120 between the first boss 110 and the convex portion 106 having a certain height, the user will not bring impurities into the contact surface 120 between the first boss 110 and the convex portion 106 when cleaning the impurities left on the bottom plate 108, making it more convenient for the user to clean.

[0092] In addition, the cavity structure 100 proposed in this embodiment has all the beneficial effects of the cavity structure 100 of the first embodiment, can reduce the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, and can avoid gluing at the connection between the back plate 104 and the surrounding plate assembly 102, avoiding the possibility of affecting the appearance of the cavity structure due to the gluing process. Here, it will not be discussed in detail.

[0093] A fourth embodiment of the present application proposes a cavity structure 100, which is further based on the third embodiment:

[0094] As shown in Figure 8 , Figure 12 and Figure 13 The bottom plate 108 further includes a second stamping structure, and the first boss 110 is directly defined by the second stamping structure. During the manufacturing process of the bottom plate 108, the bottom plate 108 can be subjected to stamping treatment, thereby forming the second stamping structure on the bottom plate 108. The second stamping structure protrudes from the plate body 118 of the bottom plate 108, thereby directly defining the first boss 110 through the second stamping structure. In addition, defining the first boss 110 through the second stamping structure can also simplify the manufacturing process of the bottom plate 108, thereby improving the manufacturing efficiency of the bottom plate 108 and the entire cavity structure 100.

[0095] Specifically, the plate body 118 mentioned above is the part of the base plate 108 that has not been stamped.

[0096] In this embodiment, further, as Figure 13 As shown, the contact surface 120 between the protrusion 106 and the first boss 110 is higher than the plate body 118. That is, the present invention supports the protrusion 106 of the back plate 104 to a certain height through the first boss 110, resulting in a certain height difference between the contact surface 120 between the protrusion 106 and the first boss 110 and the plate body 118 of the bottom plate 108. In this way, the liquid in the cooking cavity 144 drips onto the plate body 118 of the bottom plate 108 under the action of gravity, further reducing the possibility of liquid leakage in the cooking cavity 144.

[0097] In this embodiment, further, as Figure 13 As shown, the contact surface 120 between the protrusion 106 and the first protrusion 110 is arranged laterally. This significantly improves the sealing effect between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102. Specifically, the laterally arranged contact surface 120 between the protrusion 106 and the first protrusion 110 ensures that dripping liquid will not drip onto the contact surface 120 between the protrusion 106 and the first protrusion 110; and the contact surface 120 between the protrusion 106 and the first protrusion 110 is higher than the plate body 118, ensuring that liquid dripping onto the plate body 118 will not flow onto the contact surface 120 between the protrusion 106 and the first protrusion 110, thereby improving the sealing performance of the cavity structure 100.

[0098] In this embodiment, further, as Figure 13 As shown, the base plate 108 also includes an arc transition portion 122. The plate body 118 and the first boss 110 are connected by the arc transition portion 122. In this way, the arc transition portion 122 provides a good transition between the plate body 118 and the first boss 110, avoiding right angles or sharp points between them.

[0099] During the user's cleaning of the cavity structure 100, the arc transition portion 122 makes the connection between the plate body 118 and the first boss 110 easy to clean, so that impurities in the cavity structure 100 will not remain at the connection between the plate body 118 and the first boss 110, which is convenient for the user to operate and also beneficial for cleaning the cavity structure 100.

[0100] Furthermore, the cavity structure 100 proposed in this embodiment has all the beneficial effects of the cavity structure 100 in the first embodiment. It can reduce the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, and at the same time avoid the need for glue at the connection between the back plate 104 and the surrounding plate assembly 102, thus avoiding the possibility of affecting the appearance of the cavity structure due to the glue application process. This will not be discussed in detail here.

[0101] The fifth embodiment of the present invention proposes a cavity structure 100, which, based on the third and fourth embodiments, further includes:

[0102] like Figure 8 As shown, the base plate 108 includes a second protrusion 124. The second protrusion 124 is disposed on the plate body 118 of the base plate 108 and protrudes beyond the plate body 118. After the cavity structure 100 is assembled, the first side plate 112 overlaps the second protrusion 124. In this way, the second protrusion 124 supports the first side plate 112 to a certain height, ensuring that the connection between the second protrusion 124 and the first side plate 112 has a certain height. This prevents liquid inside the cavity structure 100 from overflowing from the connection between the second protrusion 124 and the first side plate 112, further reducing the possibility of liquid leakage inside the cooking cavity 144.

[0103] In this embodiment, further, as Figure 8 As shown, the base plate 108 includes a third protrusion 126. The third protrusion 126 is disposed on the plate body 118 of the base plate 108 and protrudes beyond the plate body 118. After the cavity structure 100 is assembled, the second side plate 114 overlaps the third protrusion 126. In this way, the third protrusion 126 supports the second side plate 114 to a certain height, ensuring that the connection between the third protrusion 126 and the second side plate 114 has a certain height. This prevents liquid inside the cavity structure 100 from overflowing from the connection between the third protrusion 126 and the second side plate 114, further reducing the possibility of liquid leakage inside the cooking cavity 144.

[0104] In this embodiment, such as Figure 8 As shown, the first boss 110, the second boss 124 and the third boss 126 can be an integral structure and are formed by stamping in one step.

[0105] Furthermore, the cavity structure 100 proposed in this embodiment has all the beneficial effects of the cavity structure 100 in the first embodiment. It can reduce the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, and at the same time avoid the need for glue at the connection between the back plate 104 and the surrounding plate assembly 102, thus avoiding the possibility of affecting the appearance of the cavity structure due to the glue application process. This will not be discussed in detail here.

[0106] The sixth embodiment of the present application proposes a cavity structure 100, which is further based on the third embodiment, the fourth embodiment and the fifth embodiment, and has the following features:

[0107] In this embodiment, further as shown in Figure 6 , the enclosure assembly 102 further comprises a first side plate 112, a second side plate 114 and a top plate 116. Among them, the first side plate 112 is connected to the first side of the bottom plate 108, the second side plate 114 is connected to the second side of the bottom plate 108, and the first side plate 112 and the second side plate 114 are oppositely arranged, so that one of the first side plate 112 and the second side plate 114 is used as a left side plate and the other is used as a right side plate.

[0108] In addition, as shown in Figure 6 , the top plate 116 is connected to the top of the first side plate 112 and the second side plate 114. Further, the back plate 104 is connected to the top plate 116, the first side plate 112, the second side plate 114 and the top plate 116 at the same time to ensure the stability of the entire cavity structure 100.

[0109] The back plate 104 comprises a first connecting edge 128. Among them, the first connecting edge 128 is located on the circumferential side of the convex part 106, and the back plate 104 is connected to the enclosure assembly 102 through the connecting edge to ensure the stable connection of the back plate 104.

[0110] In this embodiment, further as shown in Figure 12 and Figure 13 , the enclosure assembly 102 comprises a flange structure 130. Among them, the flange structure 130 is arranged at the edge of the enclosure assembly 102, and specifically arranged at the position of the first opening of the enclosure assembly 102. In addition, during the assembly of the cavity structure 100, the flange structure 130 of the enclosure assembly 102 is connected to the first connecting edge 128 of the back plate 104. In addition, the connection position of the first connecting edge 128 and the flange structure 130 is located outside the enclosure assembly 102, so as to facilitate the operation of the staff.

[0111] In this embodiment, further as shown in Figure 12 and Figure 13 , the flange structure 130 is vertically arranged; correspondingly, the first connecting edge 128 is also vertically arranged. In this way, during the connection of the back plate 104 by the staff, the staff can operate horizontally, which is more in line with the operation habit of the staff and is convenient for the user to operate.

[0112] In this embodiment, further as shown in Figure 12 and Figure 13As shown, the first connecting surface 132 between the first connecting edge 128 and the flanging structure 130 is vertically arranged. That is, the user can operate transversely during the process of connecting the first connecting edge 128 and the flanging structure 130. Specifically, when the user uses a fastener to connect the first connecting edge 128 and the flanging structure 130, the fastener can be directly transversely inserted through the first connecting edge 128 and the flanging structure 130, and the operation is more convenient.

[0113] In this embodiment, further, as shown in Figure 12 and Figure 13 The flanging structure 130 is located on the top plate 116, the bottom plate 108, the first side plate 112 and the second side plate 114, and the first connecting edge 128 is arranged around the convex portion 106. In this way, after the cavity structure 100 is assembled, the flanging structure 130 is connected with the first connecting edge 128, so that the four edges of the back plate 104 are connected with the surrounding plate assembly 102, which on the one hand improves the connection strength of the back plate 104 and the surrounding plate assembly 102, and on the other hand improves the sealing performance of the connection position of the back plate 104 and the surrounding plate assembly 102.

[0114] In addition, the cavity structure 100 of the present embodiment has all the beneficial effects of the cavity structure 100 of the first embodiment, can reduce the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, and can avoid gluing at the connection position of the back plate 104 and the surrounding plate assembly 102, thereby avoiding the possibility of affecting the appearance of the cavity structure due to the gluing process. Here, it will not be discussed in detail.

[0115] The seventh embodiment of the present application proposes a cavity structure 100, which is further based on the sixth embodiment:

[0116] As shown in Figure 9 The cavity structure 100 further comprises a cover 134 and a fan cavity 136. The cover 134 is arranged on the back plate 104, and the back plate 104 is located between the surrounding plate assembly 102 and the cover 134. In addition, the cover 134 and the back plate 104 have a certain space therebetween, and the fan cavity 136 is defined by the space.

[0117] Specifically, when the cavity structure 100 is applied to a cooking utensil, the fan cavity 136 is used to place a hot air fan of the cooking utensil.

[0118] In this embodiment, further, as shown in Figure 12 and Figure 13 The cover 134 comprises a second connecting edge 138. The second connecting edge 138 is connected with the first connecting edge 128 and the flanging structure 130, thereby connecting the cover 134, the back plate 104 and the surrounding plate assembly 102 into one body.

[0119] In addition, as shown in Figure 12 and Figure 13 The second connecting surface 140 between the first connecting edge 128 and the second connecting edge 138 is vertically arranged. That is, the user can operate transversely during the process of connecting the first connecting edge 128 and the flip edge structure 130. Specifically, when the user installs the cover 134 by using fasteners, the fasteners can be directly transversely inserted through the second connecting edge 138 and the first connecting edge 128 and the flip edge structure 130, and the operation is more convenient.

[0120] Specifically, as shown in Figure 12 and Figure 13 The second connecting edge 138 is located around the cover 134, and the shape of the second connecting edge 138 matches the shape of the first connecting edge 128 of the back plate 104. In this way, the four edges of the cover 134 are connected with the back plate 104, which on the one hand improves the connection strength of the cover 134 and the back plate 104, and on the other hand improves the sealing performance of the connection position of the cover 134 and the back plate 104.

[0121] On the basis of any of the above embodiments, further as shown in Figure 5 The surrounding plate assembly 102 further comprises a front plate 142 and a second opening. The front plate 142 is arranged opposite to the back plate 104, and the second opening is arranged on the front plate 142, so as to facilitate the cavity structure 100 to be used for placing food.

[0122] In addition, the cavity structure 100 provided in the embodiment has all the beneficial effects of the cavity structure 100 of the first embodiment, can reduce the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, and can avoid gluing at the connection position of the back plate 104 and the surrounding plate assembly 102, thereby avoiding the possibility that the appearance of the cavity structure is affected due to the gluing process. Details are not discussed here.

[0123] An eighth embodiment of the present application provides a cooking appliance comprising the cavity structure 100 of any of the above embodiments.

[0124] The cooking appliance provided in the embodiment comprises the cavity structure 100 of any of the above embodiments. Therefore, the cooking appliance has all the beneficial effects of the cavity structure 100 described above. In addition, the cavity structure 100 provided in the embodiment has all the beneficial effects of the cavity structure 100 of the first embodiment, can reduce the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, and can avoid gluing at the connection position of the back plate 104 and the surrounding plate assembly 102, thereby avoiding the possibility that the appearance of the cavity structure is affected due to the gluing process. Details are not discussed here.

[0125] Specifically, the cooking appliance provided in the present application can be a steam oven with hot air and a micro steam oven, and the like.

[0126] Specifically, during the use of the cooking appliance, the cooking cavity 144 of the cavity structure 100 is placed with food to be cooked. Among them, as shown in Figure 12 and Figure 13 , the convex part 106 of the back plate 104 is embedded into the inside of the surrounding plate assembly 102, and the convex part 106 of the back plate 104 is supported to a certain height by the first boss 110, so that the contact surface 120 between the convex part 106 and the first boss 110 is transversely arranged, and the contact surface 120 between the convex part 106 and the first boss 110 is higher than the plate body 118.

[0127] In this way, as shown in Figure 12 and Figure 13 , the liquid in the cooking cavity 144 falls on the plate body 118 of the bottom plate 108 under the action of gravity, and does not fall on the contact surface 120 between the convex part 106 and the first boss 110, thereby effectively improving the sealing effect between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, and obviously reducing the possibility of water seepage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102, thereby avoiding the liquid in the cooking cavity 144 from overflowing. At the same time, the connection between the back plate 104 and the surrounding plate assembly 102 can be avoided, and the possibility of affecting the appearance of the cavity structure due to the gluing process can be avoided.

[0128] Further, as shown in Figure 12 and Figure 13 , the plate body 118 and the first boss 110 are connected through the circular arc transition part 122, which can play a good transition effect between the plate body 118 and the first boss 110, avoiding the straight angle connection between the plate body 118 and the first boss 110. In the process of cleaning the cooking cavity 144 by the user, food residues can be avoided to remain at the connection position of the plate body 118 and the first boss 110, and the user operation is also facilitated, which is also conducive to the cleaning of the cavity structure 100.

[0129] Further, as shown in Figure 12 and Figure 13 , the surrounding plate assembly 102 includes a vertically arranged flange structure 130, the first connecting edge 128 of the back plate 104 is also vertically arranged, and the second connecting edge 138 of the cover body 134 is also vertically arranged. The second connecting edge 138 is connected with the first connecting edge 128 and the flange structure 130, thereby connecting the cover body 134, the back plate 104 and the surrounding plate assembly 102 into one body. In this way, when the user installs the cover body 134 by using fasteners, the fasteners can be directly transversely inserted through the second connecting edge 138 and the first connecting edge 128 and the flange structure 130, which is more convenient to operate.

[0130] Further, as shown in Figure 12 andFigure 13 As shown, the turn-up structure 130 is arranged on the bottom plate 108, the first side plate 112, the second side plate 114 and the top plate 116, and is located at the position of the first opening, the first connecting edge 128 is located around the convex portion 106, and the second connecting edge 138 matches the structure of the first connecting edge 128. In this way, the four edges of the cover 134 are connected with the back plate 104, which not only improves the connection strength of the cover 134 and the back plate 104, but also improves the sealing performance of the connection position of the cover 134 and the back plate 104.

[0131] In particular, with the development of technology, people have higher and higher requirements for the cooking utensils used, and the cavity structure of the utensil should not only be easy to clean, but also not affect the appearance by gluing, and also ensure that there is no water leakage or air leakage. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to ensure that the cover 106' can be fixed and sealed on four sides, the round corner press-type step on the back side of the bottom plate 102' is sacrificed, and at the same time, in order to ensure that there is no water leakage, the region is glued with silicone. In this way, a sanitary dead angle is easily formed at the connection position of the back plate 104' and the bottom plate 102', and the problem of not being easy to clean exists, and the gluing also affects the appearance of the cavity structure to some extent.

[0132] Therefore, as shown in Figure 5 and Figure 6 The cavity structure 100 includes a bottom plate 108, a first side plate 112, a second side plate 114, a top plate 116, a front plate 142 and a back plate 104. As shown in Figure 7 and Figure 8 The back plate 104 has a first press-type structure to form a convex portion 106, which is embedded in the structure formed by riveting the bottom plate 108, the first side plate 112, the second side plate 114 and the top plate 116, so that the bottom plate 108 can still have a first boss 110, so that the cavity structure 100 has the characteristics of easy cleaning and no water leakage. In addition, the cover 134 can be fixed on four sides to ensure that the cavity structure 100 has good sealing performance

[0133] Specifically, as shown in Figure 5 The bottom plate 108, the first side plate 112, the second side plate 114 and the top plate 116 form a cooking cavity 144 with two open ends, the front plate 142 is fixed on the cooking cavity 144 in a welded manner, and the back plate 104 is fixed at the rear of the cooking cavity 144 in a riveted manner. As shown in Figure 8 The bottom plate 108 has the first boss 110 at the position close to the back in addition to the second boss 124 and the third boss 126 on the left and right sides, which facilitates cleaning and prevents water leakage. As shown in Figure 7As shown, the back plate 104 has a protrusion 106 protruding towards the cooking cavity 144. As shown in Figure 12 and Figure 13 As shown, when the back plate 104 is fixed, the contact surface 120 of the back plate 104 is sealed by embedding the protrusion 106. As shown in Figure 12 、 Figure 13 and Figure 14 With such a structure, the bottom plate 108 also has the first boss 110 near the back plate, so that the cooking cavity 144 has the advantages of water leakage prevention, easy cleaning and no need for glue sealing. In addition, the second connecting edge 138 of the cover body 134 is tightly and sealingly installed.

[0134] In particular, as shown in Figure 12 and Figure 13 The protrusion 106 of the back plate 104 is embedded in the inner part of the surrounding plate assembly 102, and the protrusion 106 of the back plate 104 is supported to a certain height by the first boss 110. The contact surface 120 between the protrusion 106 and the first boss 110 is transversely arranged and is higher than the plate body 118. In this way, the possibility of water leakage between the back plate 104 and the bottom plate 108 of the surrounding plate assembly 102 can be significantly reduced, thereby avoiding the overflow of liquid inside the cooking cavity 144. At the same time, the connection between the back plate 104 and the surrounding plate assembly 102 can be avoided, and the possibility of affecting the appearance of the cavity structure due to the glue process can be avoided.

[0135] In particular, as shown in Figure 12 and Figure 13 The plate body 118 and the first boss 110 are connected by the arc transition part 122. The arrangement of the arc transition part 122 can avoid food residues remaining at the connection position of the plate body 118 and the first boss 110, and is convenient for user operation and is also conducive to the cleaning of the cavity structure 100.

[0136] In particular, as shown in Figure 12 and Figure 13 The surrounding plate assembly 102 includes a vertically arranged flange structure 130. The first connecting edge 128 of the back plate 104 is also vertically arranged, and the second connecting edge 138 of the cover body 134 is also vertically arranged. When the user installs the cover body 134 by using fasteners, the fasteners can be directly transversely passed through the second connecting edge 138 and the first connecting edge 128 and the flange structure 130, which is more convenient to operate.

[0137] In particular, the turn-up structure 130 is arranged on the bottom plate 108, the first side plate 112, the second side plate 114 and the top plate 116, and is located at the position of the first opening, the first connecting edge 128 is located around the convex portion 106, and the second connecting edge 138 is matched with the structure of the first connecting edge 128. In this way, the four edges of the cover body 134 are connected with the back plate 104, which improves the connection strength of the cover body 134 and the back plate 104, and also improves the sealing performance of the connection position of the cover body 134 and the back plate 104.
