[0067] In some embodiments, as shown in Figure 6 and Figure 7 , the kitchen appliance further comprises a fan unit 5 arranged horizontally in the main air duct chamber 101. In this way, the smoke suction path is shortened, and compared with the vertical fan unit 5 in the prior art, the horizontal fan unit 5 has greater suction force, so as to improve the oil fume exhaust effect. It should be noted that the horizontal arrangement of the fan unit 5 in the baffle 1 means that when the fan unit 5 is arranged in the baffle 1, the axial direction of the fan unit 5 is vertical.

[0068] In some embodiments, as shown in Figure 6 and Figure 7 , the volute 51 has a volute bottom plate 511, and an oil guiding gap 103 is arranged between the volute bottom plate 511 and the baffle bottom plate 12, and the oil guiding gap 103 is in communication with the main oil guiding groove 21 through the main oil guiding hole; the volute bottom plate 511 is provided with a fan oil dripping hole at the lowest position, and the fan oil dripping hole is in communication with the oil guiding gap 103.

[0078] Specifically, as shown in Figures 3 to 5 and Figures 8 to 10 , the bellow 1 further comprises a side oil guide structure 3, which is provided with a side oil guide groove 31 arranged directly below the second oil drain hole 121, and the side oil guide groove 31 is used to receive the oil liquid dripping from the second oil drain hole 121; the lowest position of the side oil guide groove 31 is provided with a communication oil port 32, and the side oil guide groove 31 is communicated with the main oil groove 21 through the communication oil port 32, and the communication oil port 32 is higher than the bottom wall of the main oil groove 21, and the main oil groove 21 is used to receive the oil liquid dripping from the communication oil port 32.

[0079] The oil liquid accumulated on the bellow bottom plate 12 surrounding the side air duct chamber 102 falls into the side oil guide groove 31 through the second oil drain hole 121, and the oil liquid in the side oil guide groove 31 falls into the main oil groove 21 through the communication oil port 32, and then is discharged by the oil drain pipeline 8.

[0080] In some embodiments, as shown in Figures 3 to 5 and Figures 8 to 10 , the top opening of the main oil groove 21 forms a main oil inlet, and the top opening of the side oil guide groove 31 forms a side oil inlet; the main oil guide structure 2 extends out of the bellow bottom plate 12 at one end in the left-right direction, the side oil guide structure 3 extends out of the bellow bottom plate 12 at one end in the front-rear direction and overlaps the end of the main oil guide structure 2 extending out of the bellow bottom plate 12, and the side oil guide groove 31 overlaps the end of the main oil guide structure 2 to form the communication oil port 32.

[0081] For example, the main oil groove 21 has a first side wall and a second side wall oppositely arranged along the front-rear direction, and the second side wall is located in front of the first side wall; the side oil guide structure 3 overlaps the second side wall and is bent downward to form a bent portion 33, and the bent portion 33 is located in the main oil groove 21; the bent portion 33 is connected to the second side wall by a fourth fastener such as a bolt; and the end of the side oil guide structure 3 away from the main oil guide structure 2 is fixed to the outer bottom wall of the bellow bottom plate 12.

[0082] In this way, the mode of connecting the side oil guide groove 31 and the main oil groove 21 is simplified, the structure of the kitchen appliance is simplified, and the assembly efficiency is improved.

[0083] In some embodiments, as shown in Figures 3 to 5 and Figures 8 to 10As shown, the main oil guide inlet directly below the bellow bottom plate 12 is blocked by the bellow bottom plate 12, and the side oil guide inlet directly below the bellow bottom plate 12 is blocked by the bellow bottom plate 12; the kitchen appliance further comprises a oil groove cover 4 connected with the bellow 1, the main oil guide structure 2 and the side oil guide structure 3, the oil groove cover 4 blocks the main oil guide inlet outside the bellow bottom plate 12, and the oil groove cover 4 blocks the side oil guide inlet outside the bellow bottom plate 12.

[0084] By blocking part of the main oil guide inlet and part of the side oil guide inlet with the bellow bottom plate 12, and blocking another part of the main oil guide inlet and another part of the side oil guide inlet with the oil groove cover 4, the main oil groove 21 and the side oil groove 31 are avoided from being exposed to affect the aesthetic performance of the kitchen appliance.

[0088] It should be noted that the bellow bottom plate 12 can be inclined left relative to the horizontal plane, or inclined right relative to the horizontal plane. The bellow bottom plate 12 can also be arranged to be inclined backward relative to the horizontal plane only, or arranged to be inclined relative to the left-right direction only.

[0089] In some embodiments, as shown in Figure 4 and Figure 5 , the angle α between the projection of the bellow bottom plate 12 in a first preset plane and the front-rear direction is not greater than 5°, and the first preset plane is perpendicular to the left-right direction; as shown in Figure 2 , the angle β between the projection of the bellow bottom plate 12 in a second preset plane and the left-right direction is not greater than 5°, and the second preset plane is perpendicular to the front-rear direction.

[0090] In this way, the bellow bottom plate 12 is not only inclined backward relative to the horizontal plane, but also inclined relative to the left-right direction.

[0091] It should be noted that α can be selected as any value between greater than 0° and not greater than 5°, for example, α can be selected as any one of 1°, 2°, 3°, 4° and 5°. β can be selected as any value between greater than 0° and not greater than 5°, for example, β can be selected as any one of 1°, 2°, 3°, 4° and 5°. α and β can be the same or different, which is not limited herein.

[0092] The first preset plane is parallel to the wind box bottom plate 12, and the axial direction of the above-mentioned fan unit 5 is perpendicular to the above-mentioned first preset plane, in other words, the axial direction of the fan unit 5 is perpendicular to the wind box bottom plate 12.

[0093] In some embodiments, the volute bottom plate 511 is arranged to be inclined. Exemplarily, the inclination direction of the volute bottom plate 511 is the same as the inclination direction of the wind box bottom plate 12.

Figure 4 Figure 5 In some embodiments, as shown in Figs. 1 and 2, the groove bottom wall of the side oil guiding groove 31 is arranged to be inclined. Exemplarily, the inclination direction of the groove bottom wall of the side oil guiding groove 31 is the same as the inclination direction of the wind box bottom plate 12. The oil liquid gathered on the wind box bottom plate 12 surrounding the side air duct chamber 102 converges near the second oil discharging hole 121 under the guiding effect of the inner bottom wall of the wind box bottom plate 12, and falls into the side oil guiding groove 31 below through the second oil discharging hole 121; the oil liquid gathered in the side oil guiding groove 31 converges to the communication oil port 32 under the guiding effect of the inner bottom wall of the side oil guiding groove 31, and falls into the main oil guiding groove 21 below through the communication oil port 32. It should be noted that the inclination direction of the groove bottom wall of the side oil guiding groove 31 can be different from the inclination direction of the wind box bottom plate 12.

[0096] ​Thus, the oil in the side oil guide groove 31 is guided into the main oil guide groove 21, and then discharged through the oil discharge pipeline 8 and the check valve 7. The oil accumulated on the baffle plate 12 of the main air duct chamber 101 and the oil accumulated on the baffle plate 12 of the side air duct chamber 102 are discharged through the oil discharge pipeline 8 and the check valve 7. Only one oil discharge pipeline 8 and one check valve 7 are needed, thereby reducing the number of components, reducing the cost, reducing the occupied space of the kitchen appliance, and reducing the requirement of the kitchen appliance for the installation space.

[0097] In some embodiments, as shown in Figs. 1 and 2, the kitchen appliance further comprises a first pipeline joint 61 and a second pipeline joint 62. Figure 8 and Figure 9 The one end of the first pipeline joint 61 is detachably connected with the main oil guide structure 2 and communicates with the main oil guide hole, and the other end is connected with one end of the oil discharge pipeline 8. The one end of the second pipeline joint 62 is detachably connected with the check valve 7 and communicates with the inlet through hole of the check valve 7, and the other end is connected with the other end of the oil discharge pipeline 8.

[0098] Thus, the oil discharge pipeline 8 can be easily disassembled for later maintenance. For example, the first pipeline joint 61 is detachably connected with the main oil guide structure 2 through fasteners such as bolts, and the second pipeline joint 62 is detachably connected with the check valve 7 through fasteners such as bolts.

[0099] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
