[0044] As Figure 1 shown, an inner container assembly according to an embodiment includes an inner container 100, a fixing unit 200, and a heating element 300. The fixing unit 200 is used to fix the heating element 300 on the inner container 100.

[0045] As Figure 4 shown, the inner container 100 is a hollow structure with an inner cavity 112, and at least a part of the inner container 100 is used to form a mounting portion 111. The mounting portion 111 completely separates the inner cavity 112 of the inner container 100 from the outside of the inner container 100. In other words, the mounting portion 111 is a part of the inner container 100. On the inner container 100, the mounting portion 111 completely separates the inside from the outside of the inner container 100, that is, the mounting portion 111 does not have structures such as holes or channels that communicate the inner cavity 112 of the inner container 100 with the outside.

[0046] Specifically, the mounting portion 111 is a part of the back plate 110 of the inner container 100. Of course, in other embodiments, the mounting portion 111 can also be a part of the side plate of the inner container 100, which is not limited herein.

[0047] As Figure 1 、 3As shown, the fixing unit 200 is fixed on the mounting portion 111, and without damaging the feature that the mounting portion 111 completely separates the inner cavity 112 from the outside of the inner container 100. The fixing unit 200 is used to fix the heating element 300 on the inner container 100. Specifically in this embodiment, at least part of the wall of the inner cavity 112 is used to form the mounting portion 111. The fixing unit 200 is fixed on the mounting portion 111 and is located inside the inner cavity 112. The heating element 300 is fixed on the fixing unit 200 and is located inside the inner cavity 112 to facilitate the heating element 300 to heat the food in the inner cavity 112. Of course, in other embodiments, at least part of the outer side surface of the inner container 100 is used to form the mounting portion 111. The fixing unit 200 is arranged outside the inner container 100. The fixing unit 200 is used to fix the heating element 300 on the outside of the inner container 100. The inner container 100 is a heat conductor, and the heating element 300 can transfer heat to the inner cavity 112 through the inner container 100 to heat the food in the inner cavity 112.

[0048] As Figure 1 , 3 shown, in the above-mentioned inner container assembly, the heating element 300 is fixed on the mounting portion 111 of the inner container 100 through the fixing unit 200. Since the mounting portion 111 is a part that completely separates the inner cavity 112 of the inner container 100 from the outside of the inner container 100, and the mounting portion 111 does not have structures such as holes or channels that communicate the inner cavity 112 of the inner container 100 with the outside, therefore, the method of fixing the heating element 300 through the fixing unit 200 has fewer openings in the inner container 100 compared with the method of directly fixing the heating element 300 on the inner container 100 using bolts, ensuring the sealing performance of the inner container 100.

[0049] As Figure 2 , Figure 4 shown, specifically, the fixing unit 200 includes a fixing frame 210. The heating element 300 is fixed on the fixing frame 210. The fixing frame 210 is welded and / or adhered to the mounting portion 111. The fixing frame 210 is fixed to the mounting portion 111 by welding and / or adhering, and there is no need to open holes in the mounting portion 111 to reserve mounting positions, ensuring the sealing performance of the inner container 100.

[0050] Furthermore, the fixing unit 200 further includes a support member 220 that is in limit cooperation with the fixing frame 210. The support member 220 supports the heating element 300. The installation method of the heating element 300 is that the fixing frame 210 is fixed on the mounting portion 111, and the fixing frame 210 limits the support member 220, and the support member 220 supports the heating element 300, so that the heating element 300 is fixed to the inner container 100.

[0051] Specifically, the heating element 300 is a heating tube. The heating element 300 includes a first tube section 310, a second tube section 320, and a third tube section 350. The first tube section 310 and the second tube section 320 are arranged in parallel and at intervals. The third tube section 350 is used to connect the first tube section 310 and the second tube section 320. Both ends of the support member 220 are respectively connected to the first tube section 310 and the second tube section 320. In this way, the heating element 300 is supported by the support member 220, and then the support member 220 is limited by the fixing bracket 210, so that the installation of the heating element 300 can be realized.

[0052] More specifically, hoop fasteners 222 are provided at both ends of the support member 220. The hoop fasteners 222 at both ends of the support member 220 respectively embrace the first tube section 310 and the second tube section 320, realizing the fixation of the support member 220 and the heating element 300.

[0053] As Figures 2 - 4 shown, further, the fixing bracket 210 includes a fixing portion 211 and a limiting portion 212 connected to the fixing portion 211. The fixing portion 211 is fixedly connected to the mounting portion 111. The limiting portion 212 is provided with a limiting opening 2120. The support member 220 passes through the limiting opening 2120 and is in limiting cooperation with the side wall of the limiting opening 2120. The fixing portion 211 is fixedly connected to the mounting portion 111, realizing the fixation of the fixing bracket 210 and the inner tank 100. The support member 220 passes through the limiting opening 2120, and the side wall of the limiting opening 2120 can limit the support member 220, preventing the support member 220 from moving randomly.

[0054] Specifically, the fixing bracket 210 is arranged in the inner cavity 112. The fixing portion 211 is plate-shaped. The fixing portion 211 and the mounting portion 111 are arranged in a fitting manner by welding and / or bonding. The limiting portion 212 is also plate-shaped. The limiting portion 212 extends in a direction away from the mounting portion 111. The limiting opening 2120 is a notch formed on the side of the limiting portion 212. After the support member 220 passes through the limiting opening 2120, the heating element 300 is spaced from the inner tank 100, preventing the heating element 300 from directly contacting the inner tank 100 and ensuring the uniformity of the temperature in the inner cavity 112 when the heating element 300 dissipates heat.

[0055] As Figures 1 - 3 shown, further, the side wall of the limiting opening 2120 includes a first limiting wall. The first limiting wall is in limiting cooperation with the support member 220 and is used to limit the movement of the support member 220 in the first direction. Among them, the surface where the mounting portion 111 and the fixing portion 211 are in contact is parallel to the first direction, that is, the first direction is parallel to the inner surface of the back plate 110.

[0056] Specifically, the installation part 111 is a part of the back plate 110 of the inner container 100. The fixing frame 210 is disposed in the inner cavity 112 and fixedly connected to the installation part 111. After the support member 220 passes through the limiting port 2120, it can abut against the first limiting wall, and the first limiting wall can limit the movement of the support member 220 in the first direction. Specifically, in this embodiment, the first direction is the left-right direction.

[0057] Further, the side wall of the limiting port 2120 further includes a second limiting wall, and the second limiting wall is in limiting cooperation with the support member 220. The second limiting wall is used to limit the movement of the support member 220 in the second direction close to or away from the installation part 111.

[0058] Specifically, there are two second limiting walls, and both of the two second limiting walls are parallel to the inner surface of the back plate 110. After the support member 220 passes through the limiting port 2120, it can abut against the two second limiting walls, and the two second limiting walls are used to limit the movement of the support member 220 in the second direction close to or away from the installation part 111.

[0059] Further, there are two limiting parts 212, and the two limiting parts 212 are arranged oppositely at intervals, and a limiting space is formed between the two limiting parts 212. The support member 220 has a bending part 221, and the bending part 221 is located in the limiting space. The two limiting parts 212 are used to limit the bending part 221 in the third direction. Among them, the third direction, the second direction, and the first direction are perpendicular to each other in pairs.

[0060] Specifically, both of the two limiting parts 212 are perpendicular to the inner surface of the back plate 110, and the two limiting parts 212 are arranged oppositely at intervals. The middle part of the support member 220 is bent. After the support member 220 passes through the limiting ports 2120 on the two limiting parts 212, the bending part 221 is located in the limiting space formed between the two limiting parts 212. At this time, the two limiting parts 212 can limit the movement of the bending part 221 in the third direction. Specifically, in this embodiment, the second direction is the up-down direction.

[0061] Specifically, in this embodiment, the fixing frame 210 is in a "C" shape.

[0062] As Figures 3 - 4 、 Figure 10 shown, in one of the embodiments, the installation part 111 is provided with a positioning protrusion 1110, and the fixing unit 200 is provided with a positioning hole 2110. The positioning protrusion 1110 passes through the positioning hole 2110 and is in positioning cooperation with the positioning hole 2110. In this way, when installing the fixing unit 200, the fixing unit 200 can be first sleeved on the positioning protrusion 1110 through the positioning hole 2110. After the positioning of the fixing unit 200 and the installation part 111 is realized, the fixing unit 200 and the installation part 111 are welded and / or bonded together, which can improve the installation accuracy.

[0063] Specifically, the positioning holes 2110 are formed in the fixing part 211, and the positioning protrusions 1110 are arranged on the inner wall of the back plate 110.

[0064] As Figure 2 , 4 shown, in one embodiment, the inner container assembly further includes a limiting piece 330. The limiting piece 330 is provided with a first through hole and a second through hole arranged at intervals. The inner container 100 is provided with a third through hole 113 corresponding to the first through hole and a fourth through hole 114 corresponding to the second through hole. The heating element 300 includes a first connection end 311 and a second connection end 321. The first connection end 311 passes through the first through hole and the third through hole 113, and the second connection end 321 passes through the second through hole and the fourth through hole 114. The limiting piece 330 is fixedly connected to the inner container 100. The fixing of the end part of the heating element 300 can be realized through the limiting piece 330, further improving the fixing effect.

[0065] Specifically, the heating element 300 is a heating tube. The two ends of the heating tube are the first connection end 311 and the second connection end 321. The first connection end 311 and the second connection end 321 are used for electrically connecting to the power supply. The heating element 300 generates heat by relying on the power supply. Both the heating element 300 and the limiting piece 330 are arranged in the inner cavity 112. The first connection end 311 sequentially passes through the first through hole and the third through hole 113, and the second connection end 321 sequentially passes through the second through hole and the fourth through hole 114. In this way, the first connection end 311 and the second connection end 321 can pass from the inside of the inner container 100 to the outside of the inner container 100 for wiring to connect to an external power supply.

[0066] As Figure 2 , 4 , 9 shown, further, the inner container assembly further includes a first fastener 340. The limiting piece 330 is further provided with a first assembly hole 331. The inner container 100 is provided with a fourth assembly hole 420 opposite to the second assembly hole 115. The first fastener 340 passes through the first assembly hole 331 and the second assembly hole 115 to realize the fixation of the limiting piece to the inner container 100.

[0067] Specifically, the first fastener 340 is a stud. Both the first assembly hole 331 and the second assembly hole 115 are through holes. After the first fastener 340 passes through the first assembly hole 331 and the second assembly hole 115, it is fixed by a nut. In other embodiments, the first fastener 340 is a screw rod, the first assembly hole 331 is a through hole, the second assembly hole 115 is a threaded hole, and the first fastener 340 sequentially passes through the first assembly hole 331 and the second assembly hole 115 and is threadedly connected to the second assembly hole 115.

[0068] As Figure 1As shown, in one embodiment, the inner container assembly further includes a wind hood 400, a fixing unit 200, and a heating element 300 are all located in the inner cavity 112 of the inner container 100. The wind hood 400 is located in the inner cavity 112 and covers the fixing unit 200 and the heating element 300. The wind hood 400 can cover the heating element 300, and then divide the inner cavity 112 into an installation cavity and a storage cavity. The heating element 300 and the fixing unit 200 are located in the installation cavity, and the storage cavity is used to place the object to be heated. When the heating element 300 generates heat, it can transfer the heat to the storage cavity to heat the object to be heated in the storage cavity.

[0069] As Figure 1 , Figure 4 shown, specifically, the wind hood 400 has ventilation holes 410, a blower 500 is fixed on the inner container 100, and the fan blades 510 of the blower 500 are located inside the wind hood 400. The blower 500 can discharge the heat dissipated by the heating element 300 into the inner cavity 112 through the ventilation holes 410 to heat the object to be heated.

[0070] Furthermore, an installation cavity is formed by the cooperation of the wind hood 400 and the inner wall of the inner container 100. The fan blades 510 are located in the installation cavity. The fixing frame supports the wind hood 400 and spaces the wind hood 400 from the fan blades 510. In this way, it can be avoided that the fan blades 510 directly contact the wind hood 400, affecting the use of the fan blades 510.

[0071] As Figure 1 shown, in one embodiment, the heating element 300 is fixedly arranged on the fixing unit 200 and cooperates with the fixing unit 200 to form a heating unit. The wind hood 400 and the inner wall of the inner container 100 cooperate to form at least two installation cavities. There are at least two heating units, and the at least two heating units are correspondingly arranged in the at least two installation cavities. By correspondingly installing at least two heating units in the at least two installation cavities, more and more uniform heat can enter the storage cavity, accelerating the cooking speed.

[0072] Specifically, a protrusion is formed inwardly in the middle of the back plate 110. The protrusion divides the back plate 110 into upper and lower or left and right parts. The wind hood 400 covers the back plate 110, and the middle of the wind hood 400 abuts against the protrusion, so that the wind hood 400 and the back plate 110 cooperate to form two installation cavities, and both installation cavities are provided with fan blades 510 and heating units.

[0073] As Figure 1 shown, further, the wind hood 400 is fixedly connected to the fixing unit 200, and the fixing unit 200 has the function of fixing both the heating element 300 and the wind hood 400 at the same time.

[0074] As Figure 3 , 5As shown, specifically, the fixing frame 210 further includes a wind hood mounting portion 213. The wind hood mounting portion 213 is spaced from the inner wall of the inner container 100. The wind hood 400 is fixedly connected to the wind hood mounting portion 213, and the wind hood 400 is spaced from the heating element 300. After the wind hood 400 is installed, the heating element 300 does not directly contact the wind hood 400 under the action of the fixing unit 200, ensuring the uniformity of heating.

[0075] As Figures 7 - 10 shown, more specifically, the fixing portion 211 is disposed in abutting relation with the mounting portion 111. The limiting portion 212 is connected to the mounting portion 111 and extends away from the mounting portion 111. The wind hood mounting portion 213 is connected to one end of the limiting portion 212 away from the mounting portion 111, and the wind hood mounting portion 213 is arranged side by side and spaced from the mounting portion 111. The fixing frame 210 not only functions to mount the heating element 300, but also functions to mount the wind hood 400.

[0076] Further, the inner container assembly further includes a second fastener 430. The wind hood mounting portion 213 is provided with a third assembly hole 2130, and the wind hood 400 is provided with a fourth assembly hole 420. The second fastener 430 passes through the third assembly hole 2130 and the fourth assembly hole 420 to fix the fixing frame 210 and the wind hood 400.

[0077] Optionally, the second fastener 430 is a screw, the third assembly hole 2130 is a through hole, the fourth assembly hole 420 is a threaded hole. The second fastener 430 passes through the third assembly hole 2130 and the fourth assembly hole 420 in sequence and is threadedly connected to the fourth assembly hole 420.

[0078] As Figures 4 - 7 shown, the installation method of the above inner container assembly is as follows:

[0079] First, positionally cooperate the fixing frame 210 with the positioning protrusion 1110 on the mounting portion 111, and then weld and / or bond the fixing frame 210 and the mounting portion 111; then install the heating element 300 with the support member 220 installed thereon onto the fixing frame 210, and fix the limiting piece 330 and the inner container 100 together through the first fastener 340; finally, cover the fixing frame 210 and the heating element 300 with the wind hood 400, and fix the wind hood 400 and the fixing frame 210 through the second fastener 430. In the above inner container assembly, the fixing frame 210 not only functions to mount the heating element 300, but also functions to mount the wind hood 400. Moreover, the above inner container assembly does not need to open too many holes on the inner container 100 to mount the heating element 300, ensuring the sealing performance.

[0080] As Figure 1 shown, an embodiment further relates to a cooking device, including the inner container assembly as described above.

[0081] Among them, the cooking device can be a steam box, an oven, a steam oven, etc.

[0082] In the above cooking device, the heating element 300 is fixed to the installation part 111 of the inner container 100 through the fixing unit 200. Since the installation part 111 is a part that completely separates the inner cavity 112 of the inner container 100 from the outside of the inner container 100, and there are no structures such as holes or channels on the installation part 111 that connect the inner cavity 112 of the inner container 100 with the outside, therefore, the method of fixing the heating element 300 through the fixing unit 200, compared with the method of directly fixing the heating element 300 to the inner container 100 by bolts, has fewer openings in the inner container 100, ensuring the sealing performance of the inner container 100.

[0083] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0084] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
