[0033] The following will be further described in combination with the accompanying drawings to make the technical scheme of the utility model more easily understood and mastered. Figures 1-9 The specific embodiment of the utility model will be further described in detail to make the technical scheme of the utility model more easily understood and mastered.

[0034] In the embodiment, it needs to be understood that the directions or position relations indicated by the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle part" and the like are based on the directions or position relations shown in the drawings, and are only for the convenience of describing the utility model, and thus cannot be understood as a limitation on the utility model.

[0035] In addition, in the specific embodiment, the connection or fixing mode between components is not particularly described, and the connection or fixing mode can be bolt fixing or pin fixing commonly used in the prior art, or pin shaft connection, and thus will not be described in detail in the embodiment.

[0036] As shown in the drawings, Figures 1-3 A reversing structure of a range hood air duct of an integrated cooker, comprising: an air box 1, a first fixing member 2 and an air duct member 3, the air box 1 is provided with an opening 11 at the bottom, the first fixing member 2 is connected with the air box 1, the air duct member 3 is connected with the first fixing member 2, and the air duct member 3 is aligned with the opening 11 at the bottom of the air box 1. The first fixing member 2 is provided with a first mounting member 21 at the position corresponding to the opening 11; the air box 1 is further provided with a second fixing member 5 opposite to the first fixing member 2, the second fixing member 5 is provided with a second mounting member 51, one end of the air duct member 3 is fixed through the first mounting member 21, and the other end of the air duct member 3 is fixed through the second mounting member 51.

[0037] In the embodiment, the air duct member 3 is a 90° rectangular gradually changing round pipe, which is over-rounded and has no dead angle, can not only reduce air resistance, but also reduce noise, and avoids the problem of large noise caused by the bidirectional air outlet air duct.

[0038] As shown in the drawings, Figures 4-5 The top end of the air duct member 3 is formed with a first extension member 31, and the opening 11 of the air box 1 is provided with a second extension member 111 downwardly extending, the second extension member 111 is located in the first extension member 31, and the second extension member 111 plays a positioning role and is convenient for the user to align and install.

[0039] As shown in the drawings, Figure 1 ,Figure 7 and Figure 8 As shown, the first mounting component 21 is arranged in a wrap-around shape, and the first extension component 31 is connected to the first mounting component 21. Specifically, the first mounting component 21 includes a first mounting part 211, a second mounting part 212, and a third mounting part 213 arranged adjacent to each other. The first mounting part 211, the second mounting part 212, and the third mounting part 213 are each provided with an outwardly extending guide part 214. The first mounting part 211, the second mounting part 212, and the third mounting part 213 have a certain degree of elasticity. The user only needs to move the first extension component 31 along the direction of the guide part 214 to remove it. Then, the air duct component 3 is turned in another direction, and one end of the first extension component 31 is fastened to the first mounting component 21 along the guide part 214. Then, the other end is fastened to the second mounting component 51. The reversing installation can be achieved without disassembling other parts or turning the entire air box, which is convenient for the user to operate. The first mounting part 211 and the second mounting part 212 also play a limiting role.

[0040] like Figure 3 , Figure 4 and Figure 9 As shown, a sealing element 4 is disposed between the air duct component 3 and the opening 11 to perform a sealing function, ensure sealing performance, and prevent oil leakage. Specifically, a first recess 311 is provided on the first extension component 31, and the sealing element 4 is disposed in the first recess 311. Since the sealing element 4 is prone to radial displacement, this application adopts a structure in which the first recess 311 and the sealing element 4 cooperate to avoid radial displacement of the sealing element 4.

[0041] like Figure 5 As shown, at least one reinforcing member 312 is provided on each of the two opposite ends of the first extension member 31. Specifically, the two ends that are not connected to the first mounting member 21 and the second mounting member 51 are provided with four reinforcing members 312, and the reinforcing members 312 are reinforcing ribs, which are used to increase the strength of the joint surface between the first extension member 31 and the air box 1.

[0042] like Figure 1 and Figure 6 As shown, an oil drain hole 32 is provided at the bottom of the air duct component 3 for draining grease. An oil baffle bracket 6 is provided inside the air duct component 3 to cooperate with the oil drain hole 32. The oil baffle bracket 6 can effectively prevent grease from overflowing directly from the air duct component 3 without passing through the oil drain hole 32.

[0043] The oil blocking support 6 comprises an assembly 61, the front end of the assembly 61 is provided with a blocking piece 62, the assembly 61 and the blocking piece 62 have a gap, and the assembly 61 is formed with a second recess 611. Since the air duct piece 3 is a 90° rectangular gradually changing circular pipe, the oil close to the tail of the air duct piece 3 will flow back to the middle of the air duct piece 3 along the circular structure due to the circularity, at this time, the oil is blocked by the blocking piece 62, so as to avoid the oil overflowing from the air duct piece 3, and then reflows to the oil leakage hole 32 below the second recess 611 through the gap.

[0044] A corrugated pipe 7 is connected with the air duct piece 3 through a locking piece 8, the corrugated pipe 7 is used for conveying the oil fume discharged by the smoke machine to the outdoor, the corrugated pipe 7 has good flexibility and durability, can adapt to different installation environments and use scenes, and the corrugated pipe 7 also has a certain high-temperature resistance, can withstand the high temperature generated during the working of the oil fume machine; and the locking piece 8 is used for locking the corrugated pipe 7 on the air duct piece 3, so as to avoid falling off.

[0045] The technical effects of the utility model mainly embody in the following aspects:

[0046] The utility model discloses be convenient for reversing installation, and ensure the leakproofness, prevent oil leakage.

[0047] Of course, the above is only a typical example of the utility model, in addition to this, the utility model can have other various specific implementation manners, and the technical scheme formed by equivalent replacement or equivalent transformation all fall within the scope of the utility model required to protect.
