[0002] An air fryer or an oven with an air frying function usually has a fan assembly disposed on the upper portion thereof, and the fan assembly usually includes two sets of fan blades, which are respectively used for heat dissipation and hot air circulation in the cooking cavity. However, the existing fan assembly usually has the two sets of fan blades disposed sequentially at the same end of the motor shaft, and the overall size of the fan assembly is relatively large, thus causing a large waste of space on the upper portion of the air fryer or the oven with an air frying function. Utility Model Content

[0003] Based on this, it is necessary to provide a cooking appliance that can reduce the overall volume of the fan assembly.

[0004] A cooking appliance comprises: a cooking body and a fan assembly, wherein the cooking body comprises an outer shell and an inner pot, the inner pot is arranged in the outer shell, and the inner pot surrounds a cooking cavity, the outer shell comprises a first side wall, the inner pot comprises a second side wall arranged opposite to the first side wall, an accommodating space is formed between the first side wall and the second side wall, the fan assembly is installed in the accommodating space, the fan assembly comprises a motor, a fan blade, a fixed bracket and a heat insulation assembly, the motor comprises a motor body and a motor shaft, the motor body is installed in the accommodating space through the fixed bracket, and the motor body is located on a side of the fixed bracket away from the cooking cavity, the fan blade is connected to an end of the motor shaft close to the cooking cavity, the heat insulation assembly is arranged between the fan blade and the fixed bracket, the heat insulation assembly comprises a heat insulation board and a heat insulation material layer, and the heat insulation material layer is arranged on a side of the heat insulation board close to the fixed bracket.

[0005] The cooking utensil provided by the present application can play a role of heat insulation by providing a heat insulation component, thereby reducing the heat dissipated from the cooking cavity to the motor body, so that there is no need to provide a heat dissipation fan blade to dissipate heat from the motor body. At the same time, since the thickness of the heat insulation component is smaller than the thickness of the heat dissipation fan blade, providing a heat insulation component and eliminating the heat dissipation fan blade can shorten the size of the fan assembly in the axial direction of the motor shaft, thereby reducing the overall volume of the fan assembly, thereby avoiding a large waste of space at the location where the cooking utensil is installed with the fan assembly. The heat insulation component provided by the present application includes a heat insulation board and a heat insulation material layer, the heat insulation material layer is provided on one side of the heat insulation board close to the fixed bracket, and the heat insulation board supports the heat insulation material layer, ensuring that the heat insulation material layer is installed in a preset position according to a preset shape, thereby ensuring the heat insulation effect.

[0006] In one embodiment, a distance L1 between the first side wall and the second side wall is 30 mm to 80 mm.

[0007] In this way, it is ensured that there is a sufficiently large accommodation space between the first side wall and the second side wall to install the fan assembly, and at the same time, the accommodation space is not too large, thereby ensuring that the overall structure of the cooking appliance is relatively compact.

[0008] In one embodiment, the first side wall portion protrudes outward to form an expansion area, the orthographic projection of the motor on the first side wall along the axial direction of the motor shaft is located in the expansion area, and the height L2 of the expansion area protruding relative to the first side wall is 2mm to 10mm.

[0009] In this way, the first side wall borrows a part of the space from the outside, so that the capacity of the accommodating space in the shell is larger, and in terms of visual effect, the cooking utensil looks smaller and more beautiful due to the influence of the first side wall. At the same time, the setting of the expansion area is equivalent to forming a reinforcing rib, which plays a role in strengthening the structural strength of the shell.

[0010] In one embodiment, the second side wall portion is recessed toward the cooking cavity to form a first avoidance area, the area of ​​the heat insulation component corresponding to the first avoidance area is recessed toward the first side wall to form a second avoidance area, the first avoidance area and the second avoidance area are enclosed to form a first cavity, and the fan blade is arranged in the first cavity.

[0011] In this way, by setting up the first avoidance area to borrow space from the cooking cavity, the capacity of the accommodating space can be increased without increasing the overall volume of the cooking body. At the same time, the setting of the first avoidance area is equivalent to forming a reinforcing rib, which plays a role in strengthening the structural strength of the inner pot, and is conducive to the stable installation of the fan assembly. By setting up the second avoidance area to reasonably divide the accommodating space, the first cavity has a larger space, so that the depth of the first avoidance area relative to the second side wall can be reduced, making the overall structure of the fan assembly very compact.

[0012] In one embodiment, a depth L3 of the first avoidance area recessed relative to the second side wall is 5 mm to 30 mm.

[0013] In this way, it is ensured that the setting of the first avoidance area will not affect the capacity of the cooking cavity, while the capacity of the accommodating space can be maximized, thereby making the overall volume of the cooking appliance smaller.

[0014] In one embodiment, the motor shaft is sequentially passed through the fixed bracket, the thermal insulation material layer and the thermal insulation board, the edge portion of the fixed bracket is fixedly connected to the edge portion of the thermal insulation board, and the thermal insulation material layer is clamped between the fixed bracket and the thermal insulation board.

[0015] In this way, the fixing bracket and the heat insulation assembly have a simple structure and are easy to install.

[0016] In one embodiment, the thermal insulation material layer is pre-oxidized silk or thermal insulation cotton.

[0017] Pre-oxidized silk or thermal insulation cotton has a better thermal insulation effect.

[0018] In one embodiment, the thickness L4 of the thermal insulation material layer is 1 mm to 8 mm.

[0019] In this way, the heat insulation effect can be ensured and the axial size of the fan assembly on the motor shaft can be shortened.

[0020] In one of the embodiments, a shock-absorbing pad is provided between the motor body and the fixing bracket.

[0021] In this way, the vibration of the fan assembly can be reduced, thereby reducing noise.

[0022] In one embodiment, the cooking appliance is an oven, an air fryer or an integrated stove, and the accommodating space is located above or on the side of the cooking cavity.

[0023] In this way, the size of the cooking appliance in the height direction or the lateral direction can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figures 1 to 3 The present application provides a cooking device, comprising: a cooking body 10 and a fan assembly 20. The cooking body 10 comprises an outer shell 11 and an inner pot 12. The inner pot 12 is arranged in the outer shell 11, and the inner pot 12 surrounds a cooking cavity 13. The outer shell 11 comprises a first side wall 111, and the inner pot 12 comprises a second side wall 121 arranged opposite to the first side wall. An accommodating space 14 is formed between the first side wall 111 and the second side wall 121, and the fan assembly 20 is installed in the accommodating space 14. The fan assembly 20 comprises a motor 21, a fan blade 22, a fixing bracket 23, and a heat insulation assembly 24. The motor 21 comprises a motor body 211 and a motor shaft 212. The motor body 211 is installed in the accommodating space 14 through the fixing bracket 23, and the motor body 211 is located on a side of the fixing bracket 23 away from the cooking cavity 13. The fan blade 22 is connected to an end of the motor shaft 212 close to the cooking cavity 13. The fan blade 22 forms a hot air circulation flow in the cooking cavity 13 by blowing air into the cooking cavity 13. The heat insulation component 24 is arranged between the fan blade 22 and the fixed bracket 23. The heat insulation component 24 includes a heat insulation board 241 and a heat insulation material layer 242. The heat insulation material layer 242 is arranged on the side of the heat insulation board 241 close to the fixed bracket 23. In this way, by setting the heat insulation component 24, the heat insulation effect can be achieved, and the heat dissipated from the cooking cavity 13 to the motor body 211 can be reduced, so that there is no need to set up a heat dissipation fan blade to dissipate heat from the motor body 211. At the same time, since the thickness of the heat insulation component 24 is smaller than that of the heat dissipation fan blade, therefore, the dimension L of the fan assembly 20 in the axial direction of the motor shaft 212 can be shortened by setting the heat insulation component 24 and eliminating the heat dissipation fan blade, which also reduces the overall volume of the fan assembly 20, thereby avoiding a large waste of space at the location where the fan assembly 20 is installed in the cooking appliance. The thermal insulation assembly 24 provided in the present application includes a thermal insulation board 241 and a thermal insulation material layer 242. The thermal insulation material layer 242 is arranged on one side of the thermal insulation board 241 close to the fixed bracket 23. The thermal insulation board 241 supports the thermal insulation material layer 242 to ensure that the thermal insulation material layer 242 is installed in a preset position according to a preset shape, thereby ensuring the thermal insulation effect.

[0035] See also Figure 1, the distance L1 between the first side wall 111 and the second side wall 121 is 30mm to 80mm. In this way, it is ensured that there is a large enough accommodation space 14 between the first side wall 111 and the second side wall 121 to install the fan assembly 20. At the same time, the accommodation space 14 is not too large, thereby ensuring that the overall structure of the cooking utensil is relatively compact. In some specific embodiments, the distance L1 between the first side wall 111 and the second side wall 121 can be 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, or any other value within the range of 30mm to 80mm, and L1 is preferably 45mm.

[0036] See also Figure 1 and Figure 3 , the first side wall 111 partially protrudes outward to form an expansion area 112, and the orthographic projection of the motor 21 on the first side wall 111 along the axial direction of the motor shaft 212 is located in the expansion area 112, that is, the expansion area 112 is arranged corresponding to the motor 21. The height L2 of the expansion area 112 protruding relative to the first side wall 111 is 2mm to 10mm. In this way, the first side wall 111 borrows a part of the space to the outside, so that the capacity of the accommodating space 14 in the outer shell 11 is larger, and in terms of visual effect, affected by the first side wall 111, the outer dimensions of the cooking utensil look smaller and more beautiful. At the same time, the setting of the expansion area 112 is equivalent to forming a reinforcing rib, which plays a role in strengthening the structural strength of the outer shell 11. In some specific embodiments, the height L2 of the expansion area 112 protruding relative to the first side wall 111 can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, or any other value in the range of 2mm to 10mm, and L2 is preferably 5mm.

[0037] See also Figures 1 to 3Further, a portion of the second side wall 121 is recessed toward the cooking cavity 13 to form a first avoidance area 1211, and a region of the heat insulation assembly 24 corresponding to the first avoidance area 1211 is recessed toward the first side wall 111 to form a second avoidance area 2411. The first avoidance area 1211 and the second avoidance area 2411 enclose a first cavity 15, and the fan blade 22 is arranged in the first cavity 15. In this way, by setting the first avoidance area 1211 to borrow space from the cooking cavity 13, the capacity of the accommodating space 14 can be increased without increasing the overall volume of the cooking body 10. At the same time, the setting of the first avoidance area 1211 is equivalent to forming a reinforcing rib, which plays a role in strengthening the structural strength of the inner pot 12, and is conducive to the stable installation of the fan assembly 20. By setting the second avoidance area 2411 to reasonably partition the accommodating space 14, the first cavity 15 has a larger space, so that the depth of the first avoidance area 1211 relative to the second side wall 121 can be reduced, so that the overall structure of the fan assembly 20 is very compact.

[0038] See also Figure 1 , further, the depth L3 of the first avoidance area 1211 relative to the second side wall 121 is 5mm to 30mm. In this way, it is ensured that the setting of the first avoidance area 1211 will not affect the capacity of the cooking cavity 13, while the capacity of the accommodating space 14 can be maximized, so that the overall volume of the cooking utensil is small. In some specific embodiments, the depth L3 of the first avoidance area 1211 relative to the second side wall 121 can be 5mm, 8mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 30mm, or any other value within the range of 5mm to 30mm, and L3 is preferably 10mm to 15mm.

[0039] In one embodiment, the motor 21 is a shaded-pole motor, which is cheap and can greatly reduce production costs.

[0040] See also Figure 1 and Figure 3 The motor shaft 212 is sequentially inserted through the fixing bracket 23, the heat insulating material layer 242 and the heat insulating board 241. The edge of the fixing bracket 23 is fixedly connected to the edge of the heat insulating board 241, and the heat insulating material layer 242 is clamped between the fixing bracket 23 and the heat insulating board 241. In this way, the fixing bracket 23 and the heat insulating assembly 24 are simple in structure and easy to install. Figure 3As shown, the fixing bracket 23 is provided with a first hole 231, the heat insulation material layer 242 is provided with a second hole 2421, and the heat insulation board 241 is provided with a third hole 2412. During installation, the motor shaft 212 passes through the first hole 231, the second hole 2421 and the third hole 2412 in sequence, and then is connected to the fan blade 22. The edge portion of the fixing bracket 23 is fixedly connected to the edge portion of the heat insulation board 241 to ensure that the heat insulation material layer 242 is firmly clamped between the fixing bracket 23 and the heat insulation board 241, thereby ensuring the heat insulation effect of the heat insulation material layer 242. The fixing bracket 23 and the heat insulation board 241 can be fixedly connected by fasteners (such as screws) or by snaps, and this application does not limit this.

[0041] The heat insulation material layer 242 is pre-oxidized yarn or heat insulation cotton. Pre-oxidized yarn or heat insulation cotton has a good heat insulation effect.

[0042] See also Figure 1 and Figure 2 , further, the thickness L4 of the heat insulation material layer 242 is 1mm to 8mm. In this way, the heat insulation effect can be ensured and the axial size of the fan assembly 20 on the motor shaft 212 can be shortened. In some specific embodiments, the thickness L4 of the heat insulation material layer 242 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, or any other value within the range of 1mm to 8mm, and L4 is preferably 3mm.

[0043] Furthermore, a shock-absorbing pad 25 is provided between the motor body 211 and the fixing bracket 23. In this way, the vibration of the fan assembly 20 can be reduced, thereby reducing noise. The motor body 211 can be connected to the fixing bracket 23 by fasteners such as screws, and the fasteners can simultaneously pass through the shock-absorbing pad 25, so that the shock-absorbing pad 25 is clamped between the motor body 211 and the fixing bracket 23, so that the structure is very stable.

[0044] See also Figure 1 and Figure 3, the present application may provide an oven, an air fryer or an integrated stove, and the cooking utensil is provided with an opening on the front side, through which food is taken in and out of the cooking cavity 13. In one embodiment, the accommodating space 14 is located above the cooking cavity 13, and accordingly, the fan assembly 20 is provided above the cooking cavity 13. Since the cooking utensil usually has a heating element 30, such as a heating tube, provided at the upper part of the cooking cavity 13, the fan assembly 20 is provided above the cooking cavity 13 and can blow the hot air around the heating element 30 to other positions of the cooking cavity 13, so as to realize the circulation of hot air in the cooking cavity 13, thereby achieving the effect of air frying. Of course, in other embodiments, the accommodating space may also be located at the side of the cooking cavity, and accordingly, the fan assembly is provided at the side of the cooking cavity, for example, at the side of the cooking cavity away from the opening.

[0045] It is understandable that when the fan assembly 20 is arranged above the cooking cavity 13, the motor shaft 212 is arranged along the height direction of the cooking body 10. In this way, the axial direction of the motor shaft 212 is also the height direction of the cooking body 10. It can be seen that the present application sets a heat insulation assembly 24, sets only one fan blade 22 for blowing air into the cooking cavity 13, and eliminates the fan blade for heat dissipation of the fan, so that the height dimension of the cooking utensil can be reduced. Compared with the solution of setting two fan blades in the prior art, the height dimension of the cooking utensil of the present application can be reduced by about 20 mm. Similarly, when the fan assembly is arranged on the side of the cooking cavity away from the opening, the thickness dimension of the cooking utensil can be reduced.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
