[0096] a chassis 1;
[0097] at least two inner containers 2, the inner container 2 includes a side wall member 21 formed by sequentially connecting at least two side plates 211, and an inner cavity 20 is provided in the inner container 2; the two inner containers 2 are arranged side by side or stacked in the chassis 1, and a spacing is provided between the side wall members 21 of the two inner containers 2 to form a barrier structure 3, and the barrier structure 3 is used for heat insulation between the inner cavities 20 of the two inner containers 2;
[0098] a blowing assembly 4, arranged in the chassis 1 and corresponding to the inner cavity 20 one by one, and the blowing end of the blowing assembly 4 faces the inner cavity 20.
[0099] In some embodiments, as Figure 1 , Figure 2 , Figure 24 , Figure 25 shown, the chassis 1 is used to form the frame structure of the dryer, and functions to provide support and form the outer contour.
[0100] In some embodiments, a plurality of foot pads 11 are provided at the bottom of the chassis 1, and the foot pads 11 enable a certain spacing distance to exist between the chassis 1 and the placement plane (such as a tabletop, a countertop, the ground, etc.), so as to facilitate the heat dissipation of the dryer and the routing of the power cord 12.
[0101] In some embodiments, an operation panel 13 is provided on the chassis 1, so that the operation of the dryer can be controlled through the operation panel 13.
[0102] In some embodiments, the operation panel 13 can be set to include a plurality of mechanical control buttons, and the operation of the dryer is controlled through the mechanical control buttons.
[0103] In some embodiments, the control panel 13 includes mechanical control buttons and a display screen, and the operation of the dryer is controlled through the cooperation of the mechanical control buttons and the display screen.
[0104] In some embodiments, the control panel 13 is set as an integrated touch screen, such as Figure 1 , Figure 25 shown.
[0105] For the specific setting and working principle of the above-mentioned control panel 13, reference can be made to the prior art, and no specific limitation is made here.
[0106] In some embodiments, the inner container 2 can be understood as the core component of the dryer after removing the outer shell 16. For a single inner container 2, it includes the inner cavity 20 and the side wall structure surrounding the inner cavity 20. Therefore, the inner container 2 includes but is not limited to its literal interpretation meaning, and includes but is not limited to the application examples introduced in the solution of this embodiment.
[0107] In some embodiments, the inner container 2 includes the side wall member 21 and the inner cavity 20; wherein, the inner cavity 20 is used for temporarily storing the food to be processed, and the side wall member 21 serves as at least part of the side wall structure of the inner cavity 20.
[0108] In some embodiments, two of the inner containers 2 are arranged side by side, such as Figure 1 shown.
[0109] In some embodiments, two of the inner containers 2 are arranged in a stacked manner, such as Figure 25 shown.
[0110] In some embodiments, the dryer in the solution of this embodiment can also be used for items such as medicinal materials and utensils that need to be air-dried, and no specific limitation is made here.
[0111] In some embodiments, the air supply component 4 is used to supply air into the inner cavity 20; for example, the food to be processed is placed in the inner cavity 20, and then the air supply component 4 is started to air-dry the food in the inner cavity 20. Among them, since there are at least two inner containers 2, there are also at least two inner cavities 20, and the air supply component 4 and the inner cavity 20 are arranged in a one-to-one correspondence. Therefore, by controlling the operation of a specific air supply component 4, the food in a specific inner cavity 20 can be air-dried, so that the food processing operations between different inner cavities 20 can be carried out independently of each other.
[0112] As an application example, the number of the side plates 211 is two, and the cross-sectional shape of the side wall member 21 is in an "L" shape;
[0113] Alternatively, the number of the side plates 211 is three, and the cross-sectional shape of the side wall member 21 is "U" shaped;
[0114] Alternatively, the number of the side plates 211 is four, and the cross-sectional shape of the side wall member 21 is "square" shaped.
[0115] In some embodiments, as Figure 3 、 Figure 4 shown, the number of the side plates 211 on the side wall member 21 can be set to two. At this time, the two side plates 211 are integrally connected and in an "L" shape; when the cross-sectional shape of the inner cavity 20 is rectangular, additional auxiliary plates 22 serving as the other two sides need to be added. After the added auxiliary plates 22 are connected to the side wall member 21, an enclosed side wall structure of the inner cavity 20 is formed.
[0116] In some embodiments, the auxiliary plate 22 can be an integral member, as Figure 3 shown by the inner container 2 on the right side in
[0117] In some embodiments, the auxiliary plate 22 can be formed by connecting two separate plate members, as Figure 3 shown by the inner container 2 on the left side in
[0118] At this time, taking the case where the inner containers 2 are arranged side by side as an example, the formation method of the barrier structure 3 can be referred to Figures 3 to 6 shown.
[0119] When the inner containers 2 are arranged in a stacked manner, the formation method of the barrier structure 3 can be obtained by rotating the formation method of the barrier structure 3 when the inner containers 2 are arranged side by side by 90°, which will not be elaborated here.
[0120] In some embodiments, as Figure 7 、 Figure 8 、 Figures 14 to 18 、 Figure 22 、 Figure 26 shown, the number of the side plates 211 can be set to three. The three side plates 211 are integrally connected and in a "U" shape; here, continuing to take the case where the cross-sectional shape of the inner cavity 20 is rectangular as an example, only one auxiliary plate 22 can be added, and then after the auxiliary plate 22 is connected to the side wall member 21, an enclosed side wall structure of the inner cavity 20 is formed, as Figure 7 、 Figure 8 shown.
[0121] At this time, taking the case where the inner containers 2 are arranged side by side as an example, the formation method of the barrier structure 3 can be referred to Figures 7 to 12 、 Figure 15 、 Figure 26as shown
[0122] In some embodiments, the number of the side plates 211 can be set to four. At this time, the four side plates 211 are connected together to form a "mouth" shape, that is, the cross-sectional shape of the inner cavity 20 is rectangular, and the side wall member 21 serves as an enclosed side wall structure of the inner cavity 20.
[0123] In some embodiments, taking the case where the inner containers 2 are arranged side by side as an example, in this case, one of the side plates 211 of each of the two side wall members 21 serves as the bottom plate 201 of the inner container 2, and the bottom plates 201 of the two inner containers 2 can be connected together by a connecting plate 23, as Figure 5 、 Figure 8 as shown
[0124] In some embodiments, the bottom plates 201 of the two inner containers 2 are the same plate member, as Figure 6 、 Figure 9 as shown
[0125] As an application example, the side wall member 21 is integrally formed;
[0126] Or, the adjacent side plates 211 on the side wall member 21 are spliced and connected, and a seal is formed at the splicing position between the adjacent two side plates 211.
[0127] In some embodiments, the side wall member 21 is integrally formed, for example, by bending a whole plate or liquid casting.
[0128] In some embodiments, the side wall member 21 is formed by splicing. At this time, the side plates 211 are independent plate members, and then they are connected to form a whole through the connection between the side plates 211; among them, the connection between the side plates 211 can adopt a welded and sealed connection method.
[0129] In some embodiments, the side plates 211 can be connected by fasteners such as screws. When using fasteners such as screws for connection, a sealing gasket can be arranged at the connection position between the side plates 211 to ensure the sealing effect at the connection.
[0130] In some embodiments, glue is coated at the connection position between the side plates 211 to achieve sealed connection between the two through the glue.
[0131] As an application example, the side plate 211 includes a first side plate 2111 and a second side plate 2112, and the first side plate 2111 and the second side plate 2112 are respectively arranged on both sides of the inner cavity 20;
[0132] On the first side plate 2111 and the second side plate 2112, a plurality of ribs 24 are protrudingly provided towards the inner cavity 20. The plurality of ribs 24 are arranged at intervals in the vertical direction, and the ribs 24 on the first side plate 2111 and the second side plate 2112 correspond to each other.
[0133] In some embodiments, such as Figure 15 , Figure 26 shown, each inner cavity 20 is provided with the first side plate 2111 and the second side plate 2112, and the first side plate 2111 and the second side plate 2112 are respectively arranged on the left and right sides of the inner cavity 20.
[0134] In some embodiments, the ribs 24 can be formed on the first side plate 2111 and the second side plate 2112 by stamping; at this time, the ribs 24 protrude towards the inner cavity 20, and the back of the ribs 24 forms grooves 241 on the back sides of the first side plate 2111 and the second side plate 2112. This formation method of the ribs 24 can not only facilitate improving the structural strength of the first side plate 2111 and the second side plate 2112, but also facilitate reducing the weight of the first side plate 2111 and the second side plate 2112.
[0135] In some embodiments, the ribs 24 on the first side plate 2111 and the second side plate 2112 are symmetrically arranged.
[0136] In some embodiments, there is only a one-to-one correspondence in position height between the ribs 24 on the first side plate 2111 and the second side plate 2112, and the shapes and sizes of the ribs 24 at the same height can be set to be different.
[0137] By providing the ribs 24, a certain supporting effect can be formed, so as to facilitate cooperation with the tray 14, the bracket 15, etc.; for example, place the food to be processed on the tray 14, and then place the tray 14 on the ribs 24 on both sides, so that the food to be processed can be in the middle position of the inner cavity 20 during processing, and the processing effect is better. By arranging the ribs 24 in a form with intervals in the height direction, it is convenient to install multiple trays 14 and multiple brackets 15 in the same inner cavity 20, and it is also possible to make a single tray 14 have multiple placement options in terms of position height in the inner cavity 20, such as Figure 26 shown.
[0138] As an application example, such as Figure 13As shown, the side plate 211 includes an inner side plate 2113 and an outer side plate 2114, and there is a hollow sandwich layer 2115 between the inner side plate 2113 and the outer side plate 2114.
[0139] In some embodiments, each of the side plates 211 is provided as a double-layer structure. At this time, each side plate 211 includes an inner side plate 2113 and an outer side plate 2114, and the inner side plate 2113 and the outer side plate 2114 are sealed and connected at their edges, such as by welding and sealing; and a hollow sandwich layer 2115 is formed between the inner side plate 2113 and the outer side plate 2114. By providing the hollow sandwich layer 2115, the heat preservation performance of the inner cavity 20 can be improved, and the heat insulation performance between two adjacent inner cavities 20 can be further improved.
[0140] As an application example, the heat conduction coefficients of the inner side plate 2113 and the outer side plate 2114 are different.
[0141] In some embodiments, the inner side plate 2113 and the outer side plate 2114 can be made of the same material. For example, both the inner side plate 2113 and the outer side plate 2114 are made of a metal material. At this time, the heat conduction coefficients of the inner side plate 2113 and the outer side plate 2114 are close or the same.
[0142] In some embodiments, the inner side plate 2113 and the outer side plate 2114 can be made of different materials. For example, the inner side plate 2113 can be made of a metal material, and at this time, the outer side plate 2114 can be made of a rubber material. Another example is that the inner side plate 2113 can be made of a rubber material, and the outer side plate 2114 is made of a metal material. At this time, the heat conduction coefficients of the inner side plate 2113 and the outer side plate 2114 are different.
[0143] By selecting and designing the heat conduction coefficients of the inner side plate 2113 and the outer side plate 2114, the side plate 211 composed of the inner side plate 2113 and the outer side plate 2114 can have better heat insulation performance and is convenient for cost control.
[0144] As an application example, the barrier structure 3 is an air gap layer 31;
[0145] The chassis 1 includes a housing 16, and a plurality of exhaust holes 161 are provided on the housing 16. An over-flow space 162 is formed between the housing 16 and the inner container 2, and the over-flow space 162 communicates the air gap layer 31 and the exhaust holes 161.
[0146] In some embodiments, the barrier structure 3 is an air gap layer 31 formed by spacing between the two side plates 211. For reference hereFigures 3 to 9 , Figure 15 , Figure 26 as shown
[0147] In some embodiments, such as Figure 15 , Figure 26 shown, at least two of the inner containers 2 form an inner container assembly 25 after installation. The chassis 1 includes the inner container assembly 25 and the outer shell 16. At this time, the outer shell 16 covers the inner container assembly 25, so as to form the flow-through space 162 between the inner container assembly 25 and the outer shell 16.
[0148] In some embodiments, such as Figure 14 , Figure 15 shown, when the two inner containers 2 are arranged side by side, the flow-through space 162 is formed between the left and right outer side surfaces of the inner container assembly 25 and the outer shell 16, and between the top of the inner container assembly 25 and the outer shell 16. As shown in Figures 25 to 27 shown, when the two inner containers 2 are arranged in a stacked manner, the flow-through space 162 can be formed between the left and right outer side surfaces of the inner container assembly 25 and the outer shell 16. Thus, the air separation layer 31 can always be within the coverage range of the flow-through space 162.
[0149] As an application example, the exhaust holes 161 are arranged in a strip shape, and a plurality of the exhaust holes 161 are arranged side by side in the vertical direction on the side surface of the outer shell 16.
[0150] In some embodiments, such as Figure 1 , Figure 25 shown, the exhaust holes 161 are arranged on the left and right side surfaces of the chassis 1.
[0151] As an application example, as shown in Figures 14 to 16 shown, the chassis 1 includes an upper cover plate 17, the cross-sectional shape of the side wall member 21 is in a "U" shape, and the U-shaped openings of the two side wall members 21 face the upper cover plate 17 and are hermetically connected to the upper cover plate 17;
[0152] A first through hole 171 communicating with the air separation layer 31 is formed on the upper cover plate 17.
[0153] In some embodiments, the cross-sectional shape of the side wall member 21 is set to be in a "U" shape, and then the inner container 2 is formed by connecting the side wall member 21 and the upper cover plate 17. At this time, the inner side surfaces of the three side plates of the side wall member 21 and the inner side surface of the upper cover plate 17 together serve as the side wall structure of the inner cavity 20; after the two side wall members 21 and the upper cover plate 17 are connected, the inner container assembly 25 can be formed, as shown inFigure 15 as shown
[0154] By providing one of the upper cover plates 17 and mounting the side wall members 21 on the upper cover plate 17 to form the inner container assembly 25, the upper cover plate 17 can not only serve as a component of the inner cavity 20, reducing the material consumption of the side wall members 21; at the same time, it can also facilitate being the top side of the inner container assembly 25, thereby facilitating improving the structural strength of the inner container assembly 25 and enhancing the stability of the inner cavity 20 during application.
[0155] In some embodiments, such as Figure 17 、 Figure 18 、 Figure 22 as shown, bending edges 2116 are provided at the ends of the first side plate 2111 and the second side plate 2112, and mounting holes 2117 are provided in some of the bending edges 2116; the two inner cavities 20 can be connected by passing fasteners such as bolts through the mounting holes 2117.
[0156] In some embodiments, the installation of the side wall member 21 and the formation of the air gap layer 31 can also be achieved through the connection between the bending edges 2116 of the first side plate 2111 and the second side plate 2112 and the upper cover plate 17. At this time, the air gap layer is communicated with the first through hole provided on the upper cover plate.
[0157] As one application example, such as Figure 22 as shown, a sealing strip 26 is provided between the side wall member 21 and the upper cover plate 17;
[0158] The width of the sealing strip 26 corresponds to the thickness of the side plate 211; alternatively, the width of the sealing strip 26 corresponds to the width of the barrier structure 3, and a second through hole 261 is provided on the sealing strip 26, and the second through hole 261 corresponds to the first through hole 171.
[0159] In some embodiments, the sealing strip 26 is designed corresponding to the width of the bending edges 2116 on the first side plate 2111 and the second side plate 2112 respectively. At this time, only the first through hole 171 is provided on the upper cover plate 17, and the air gap layer 31 is directly communicated with the outside through the first through hole 171.
[0160] In some embodiments, the sealing strip 26 can also be designed corresponding to the width of the air gap layer 31, so that after a single sealing strip 26 is installed, it can simultaneously seal between the side plate 211 and the upper cover plate 17 on both sides of the air gap layer 31, such as Figure 22As shown in the figure; at this time, a second through hole 261 is provided on the sealant strip 26, and the air isolation layer 31 is sequentially communicated with the outside through the second through hole 261 and the first through hole 171.
[0161] By providing the air isolation layer 31, it is possible to facilitate the isolation of two adjacent inner chambers 20 to prevent the temperature of one inner chamber 20 from affecting the temperature of the other inner chamber 20, that is, to avoid the phenomenon of temperature cross. At this time, the transferred temperature will overflow in the air isolation layer 31, and by communicating the air isolation layer 31 with the outside, it is possible to facilitate the dissipation of the heat in the air isolation layer 31.
[0162] In some embodiments, as Figure 2 shown, the chassis 1 includes a bottom side plate 18, and a plurality of fourth through holes 181 are provided on the bottom side plate 18, and the fourth through holes 181 are communicated with the air isolation layer 31. At this time, the heat in the air isolation layer 31 can be directly discharged to the outside from the fourth through holes 181.
[0163] As an application example, as Figure 28 shown, the chassis 1 includes a rear cover plate 19, and the rear end of the side wall member 21 is hermetically connected to the rear cover plate 19;
[0164] A third through hole 191 communicating with the air isolation layer 31 is provided on the rear cover plate 19.
[0165] As an application example, an exhaust fan 163 is provided in the chassis 1, and the air supply end of the exhaust fan 163 is arranged facing the air isolation layer 31;
[0166] Airflow enters the air isolation layer 31 under the action of the exhaust fan 163 and is discharged from the exhaust hole 161 after passing through the flow-through space 162.
[0167] In some embodiments, the exhaust fan 163 is arranged at the rear side of the rear cover plate 19, and the air supply end of the exhaust fan 163 is arranged facing the third through hole 191, so that airflow can be input into the air isolation layer 31 from the third through hole 191 and then output from the flow-through space 162 and the exhaust hole 161, so as to improve the controllability of the temperature in the air isolation layer 31.
[0168] In some embodiments, the exhaust fan 163 can be set to a blowing mode or a suction mode. When set to the blowing mode, the exhaust fan 163 is arranged at the rear side of the rear cover plate 19; when set to the suction mode, the exhaust fan 163 can be arranged in the flow-through space 162.
[0169] As one of the application examples, such as Figure 28 shown, at least one layer of barrier net 27 is provided between the side wall member 21 and the rear cover plate 19;
[0170] The connection between the side wall member 21 and the barrier net 27 and the connection between the rear cover plate 19 and the barrier net 27 are hermetically connected.
[0171] By providing the barrier net 27, it is possible to facilitate improving the safety protection level of the dryer. For example, it can prevent users from accidentally touching the air supply assembly 4 at the rear end of the dryer during use, avoiding accidental injury to users.
[0172] In some embodiments, such as Figure 28 shown, the barrier net 27 includes a first partition net 271 and a second partition net 272, and the first partition net 271 and the second partition net 272 are arranged in a stacked manner. Among them, the mesh of the first partition net 271 and the second partition net 272 can be set to be the same or different; for example, the mesh of the first partition net 271 is set to be square, as Figure 29 shown; then the mesh of the second partition net 272 is set to be diamond-shaped, as Figure 30 shown.
[0173] In some embodiments, the two inner chambers 20 share the same barrier net 27. By hermetically separating the adjacent two inner chambers 20 through the barrier net 27, it is possible to facilitate improving the overall structural strength of the inner tank assembly 25, and at the same time, it can cooperate with the setting of the third through hole 191 to reduce the heat transfer on the barrier net 27, and the design is more ingenious.
[0174] As one of the application examples, a wind guiding structure 192 is provided on the rear cover plate 19 corresponding to the air supply assembly 4 in a horn shape.
[0175] In some embodiments, the air supply assembly 4 is provided at the narrow end of the horn shape of the wind guiding structure 192, and the flared end of the wind guiding structure 192 faces the inner chamber 20, and the shape of the flared end of the wind guiding structure 192 is adapted to the cross-sectional shape of the corresponding inner chamber 20.
[0176] By providing the wind guiding structure 192, it is possible to facilitate improving the air supply uniformity of the air supply assembly 4, so that the food can be subjected to a more uniform air drying effect in the inner chamber 20, improving the food production quality, and also facilitating energy consumption reduction.
[0177] As one of the application examples, the mesh density of the barrier net 27 is uniformly arranged;
[0178] Alternatively, the mesh density of the barrier net 27 decreases from the central region of the inner cavity 20 towards the outer edge.
[0179] In some embodiments, as Figure 29 , Figure 30 shown, the mesh density of the barrier net 27 can be set to be uniform, such as each mesh being set as a polygon with the same size; especially when paired with the air guiding structure 192, the mesh structure of the barrier net 27 will not have too much impact on the air supply uniformity at this time.
[0180] In some embodiments, as Figure 31 shown, the mesh density of the barrier net 27 can be set to decrease from the central region of the inner cavity 20 towards the outer edge. In this structural form during application, it can not only achieve the protective effect and prevent users from directly touching the air supply assembly 4; at the same time, it can also reduce the influence of the concentrated airflow output by the air supply assembly 4 acting on the central region of the inner cavity 20, which brings inconsistent food processing degrees.
[0181] As one application example, as Figure 19 , Figure 27 shown, the air supply assembly 4 includes a fan 41 and a heating element 42, and the fan 41 is used to deliver the heat dissipated by the heating element 42 into the inner cavity.
[0182] In some embodiments, as Figure 27 shown, the front side of the fan 41 faces the inner cavity 20, the heating element 42 is arranged at the rear side of the fan 41, and the fan 41 is arranged on the rear cover plate 19.
[0183] In some embodiments, the heating element 42 can be set in application forms such as heating wires and heating tubes.
[0184] As one application example, a temperature sensor 28 for detecting the working temperature is arranged in the inner cavity 20, and the working temperature of the inner cavity 20 is set to be less than 100 °C.
[0185] In some embodiments, each inner cavity 20 is provided with the temperature sensor 28, so as to detect and feedback the working temperature of the inner cavity 20 through the temperature sensor 27.
[0186] In some embodiments, controlling the working temperature of the inner cavity 20 to be less than 100 °C can facilitate improving the air-drying quality of food and enhancing the taste.
[0187] As one application example, a wind baffle 43 is arranged between two adjacent air supply assemblies 4.
[0188] In some embodiments, the wind deflector 43 is installed on the rear cover plate 19 to block between two adjacent air supply components 4, so as to avoid the phenomenon of temperature cross between the air supply components 4.
[0189] In some embodiments, there are two wind deflectors 43, and the exhaust fan 163 is arranged between the two wind deflectors 43.
[0190] As an application example, the rotation directions of the fans 41 between two adjacent air supply components 4 are set in opposite directions. Here, an example with two fans 41 is used for illustration, and the operator stands in front of the dryer:
[0191] In some embodiments, when the two inner chambers 20 are arranged side by side in the horizontal direction, the fan 41 on the left side can be set to rotate counterclockwise, while the fan 41 on the right side can be set to rotate clockwise;
[0192] In some embodiments, when the two inner chambers 20 are arranged in a stacked manner in the vertical direction, the fan 41 on the upper side can be set to rotate counterclockwise, while the fan 41 on the lower side can be set to rotate clockwise.
[0193] By designing the rotation direction of the fan 41, when the fan 41 outputs hot air, the main flow direction of the hot air is away from the air gap layer 31 between the two inner chambers 20, so as to avoid the rapid temperature rise caused by the direct impact of the hot air on the air gap layer 31; moreover, the rotation directions of two adjacent fans 41 are set in opposite directions, which can also effectively reduce the vibration amplitude and operating noise of the equipment during operation.
[0194] As an application example, as Figure 20 , Figure 21 shown, at least two fans 41 are provided on the air supply component 4.
[0195] In some embodiments, as Figure 20 shown, three fans 41 are provided on the same air supply component 4, and the three fans 41 are arranged in an equilateral triangle.
[0196] In some embodiments, as Figure 21 shown, four fans 41 are provided on the same air supply component 4, and the four fans 41 are arranged in a matrix.
[0197] In actual applications, the number of fans 41 provided can be selected based on the volume of the inner chamber 20 and the size and power of the fan 41 itself, and no specific limitation is made here.

[0199] The fan 41 is disposed on the swing frame 51 .
[0200] In some embodiments, the swing frame 51 can be rotatably installed on the chassis 1 around the axis joint 511, and the fan 41 of the air supply assembly 4 is installed on the swing frame 51, so that the fan 41 can swing with the rotation of the swing frame 51, that is, the shaking motion of the fan 41 can be realized.
[0201] In some embodiments, the first driver 52 is configured as a first motor. In this case, the first motor is connected to the swing frame 51 through a swing arm 53, so that the swinging motion of the swing frame 51 can be controlled by controlling the drive of the first motor.
[0202] By setting up the first wind control device 5, the fan 41 of the air supply assembly 4 can be shaken, thereby facilitating the multi-angle air supply of the fan 41 in the inner chamber 20, thereby improving the air-drying effect of food.
[0203] As an example of one application, Figure 22 , Figure 23 As shown, the chassis 1 is provided with a second wind control device 6, the second wind control device 6 corresponds to the inner chamber 20 one by one, and the second wind control device 6 includes a mounting frame 61, a plurality of wind guide plates 62 movably arranged on the mounting frame 61, and a second driver 63 for driving the wind guide plates 62 to swing;
[0204] The air guide plate 62 is disposed between the fan 41 and the inner chamber 20 .
[0205] In some embodiments, each of the air guide plates 62 is rotatably mounted on the mounting frame 61, and the second driver 63 is configured as a second motor, and the second motor is transmission-connected to the air guide plate 62; by controlling the operation of the second motor, the swing angle of the air guide plate 62 can be controlled, so that the air supply uniformity of the fan 41 can be improved through the air guide plate 62.
[0206] In some embodiments, Figure 23As shown, a first gear 621 is provided at the end of each air deflector 62, and the first gears 621 on different air deflectors 62 are connected by chain drive. Thus, when one air deflector 62 rotates, the other air deflectors 62 will also rotate accordingly.
[0207] In some embodiments, the first gears 621 on different air deflectors 62 are connected by rack drive.
[0208] In some embodiments, a second gear 622 is provided at the end of one air deflector 62, and the second motor is meshed with the second gear 622. Thus, one air deflector 62 is driven to rotate by the second motor, and then the other air deflectors 62 are driven to rotate.
[0209] As an application example, as Figure 10 shown, the barrier structure 3 is a vacuum space 32.
[0210] In some embodiments, after adjacent two side wall members 21 are spaced apart, the periphery of the air layer 31 formed between the adjacent two side wall members 21 is sealed, and the sealed air layer 31 is evacuated, so as to form a vacuum space 32 between the two side wall members 21. And being in the form of a vacuum space 32 can further improve the heat insulation performance.
[0211] As an application example, as Figure 11 shown, the barrier structure 3 is filled with a heat insulation filler 33.
[0212] In some embodiments, a heat insulation filler 33 is filled in the air layer 31 formed between adjacent two side wall members 21, so that the heat transfer between the two side wall members 21 can be reduced by the filled heat insulation filler 33.
[0213] In some embodiments, as Figure 12 shown, a heat insulation coating layer 34 is coated on the two inner side surfaces of the air layer 31, so as to facilitate reducing the heat transfer between the two side wall members 21.
[0214] As an application example, as Figure 1 、 Figure 25 shown, a lifting groove 164 is provided on the side surface of the chassis 1.
[0215] In some embodiments, lifting grooves 164 are provided on both the left and right side surfaces of the chassis 1.

[0217] In some embodiments, the plug receiving groove 182 is recessed in the bottom side plate 18 of the chassis 1.

[0218] As one of the application examples, such as Figure 24 shown, a dust cover 7 is provided at the rear side of the chassis 1.
[0219] In some embodiments, in order to facilitate the flow of air, a plurality of ventilation holes 101 are formed in the rear side plate of the chassis 1, and the dust cover 7 is arranged outside the plurality of ventilation holes 101 to prevent external sundries from accidentally entering the chassis 1, thereby affecting the application of the air supply component 4 and improving the application safety.
[0220] In some embodiments, the dust cover 7 includes a cover body 71 for mounting on the chassis 1, and a plurality of hollow areas 72 are provided on the cover body 71, and a screen is provided in the hollow areas 72.

[0222] Or, at least two of the inner cavities 20 share one cabinet door 8.
[0223] In some embodiments, the number of the cabinet doors 8 is set to be in one-to-one correspondence with the number of the inner cavities, so that the use of a specific inner cavity 20 can be independently controlled during use.
[0224] In some embodiments, a plurality of the inner cavities 20 can also be set to share one cabinet door 8, and no specific limitation is made here.
[0225] Compared with the prior art, the solution of this embodiment has at least the following beneficial effects:
[0226] In the solution of this embodiment, the barrier structure 3 is formed between the side wall members 21 of the two inner liners, so that the barrier structure 3 can be used to separate the inner cavities 20 of the two inner liners 2, thereby facilitating the reduction of heat transfer between the inner cavities 20 of two adjacent ones, reducing or even avoiding the influence of temperature and odor mixing between different inner cavities 20, improving the independence between different inner cavities 20 during food processing, and enabling users to have a better use experience.
