[0039] Embodiment 1

[0040] As Figure 1 shown, the cleaning structure provided by the utility model is used to clean the outer wall of the smoke pipe 2. Among them, the smoke pipe 2 is arranged on the tabletop 1, and a cooker is also arranged on the tabletop 1 beside the smoke pipe 2. The smoke pipe 2 absorbs the oil fume generated during the cooking of the cookware on the cooker through the smoke inlet.

[0041] The cleaning structure includes a roller brush mechanism 3, and the roller brush mechanism 3 can move relative to the smoke pipe 2. In this embodiment, the smoke pipe 2 can move up and down relative to the tabletop 1, and the roller brush mechanism 3 is arranged at a position below the tabletop 1. When the smoke pipe 2 needs to be cleaned, the smoke pipe 2 moves downward, and during the movement, the roller brush mechanism 3 is in full contact with the outer wall of the smoke pipe 2.

[0042] In another feasible solution, the smoke pipe 2 can be set to be fixed relative to the tabletop 1, while the whole roller brush mechanism 3 can be set to be capable of lifting. Thus, when the smoke pipe 2 needs to be cleaned, the roller brush mechanism 3 moves upward. During the movement, the roller brush mechanism 3 is in full contact with the outer wall of the smoke pipe 2.

[0043] The roller brush mechanism 3 includes a roller brush 4 and a driving mechanism (not shown in the figure). The driving end of the driving mechanism is connected to the roller brush 4 and is used to drive the roller brush 4 to rotate around the axis of the roller brush 4; the brush surface of the roller brush 4 is in contact with the outer wall of the smoke pipe 2. The driving mechanism can include a motor. The power output shaft of the motor is coaxially arranged with the roller brush 4, and moreover, the motor is connected to one end of the roller brush 4. A rotating seat can be connected to the other end of the roller brush 4, and the roller brush 4 and the rotating seat can be connected through a bearing.

[0044] When the outer wall of the smoke pipe 2 needs to be cleaned, the roller brush 4 is in contact with the side wall of the smoke pipe 2. The rotating roller brush 4 can brush the outer wall of the smoke pipe 2. The roller brush mechanism 3 and the smoke pipe 2 generate relative movement, so that the roller brush mechanism 3 can clean all positions of the outer wall of the smoke pipe 2, reduce the oil stain on the outer wall of the smoke pipe 2, and achieve the purpose of cleaning the smoke pipe 2.

[0045] As Figure 1 shown, the cleaning structure includes a steam generator 5. The steam generator 5 has a steam outlet 51, and the steam outlet 51 faces the roller brush 4.

[0046] The steam generator 5 belongs to the prior art and generates steam by heating water. The steam outlet 51 of the steam generator 5 faces the roller brush 4, which can form a humid and hot environment around the roller brush 4. In the humid and hot environment, the oil stain is easier to be removed.

[0047] The cleaning structure includes a cooking device. The cooking device can generate steam, and the cooking device forms the steam generator 5.

[0048] The cooking device can be a steam box or an oven, which will generate steam during its working process. Setting the steam outlet 51 to face the outer wall of the smoke pipe 2 in the cleaning position can keep the outer wall of the smoke pipe 2 in a humid environment, which is convenient for the cleaning structure to remove the oil stain on the outer wall. The waste steam generated by the cooking device is reused, and there is no need to additionally set a steam generator 5.

[0049] Roller brush mechanisms 3 are correspondingly arranged on all the surfaces of the smoke pipe 2 with smoke inlets, and all the smoke inlets are covered by the cleaning range of the roller brush mechanisms 3.

[0050] In this embodiment, the smoke pipe 2 is arranged between two cooktops. The cross-sectional shape thereof is generally quadrilateral, and smoke inlets are arranged on the left and right sides, so as to absorb the oil fumes generated by the cookware on the left and right sides. Therefore, the brush roller mechanisms 3 can be arranged only on the left and right sides of the smoke pipe 2. Moreover, when the smoke pipe 2 moves up and down, the brush rollers 4 on the brush roller mechanisms 3 can brush the smoke inlets, making the smoke inlets cleaner. In other embodiments, the cross-sectional shape of the smoke pipe 2 can be circular, oval, polygonal, etc.

[0051] Brush roller mechanisms 3 are arranged on all circumferential sides of the smoke pipe 2. That is to say, the brush roller mechanisms 3 are arranged not only in the direction of the surface facing the cooktops, but also in the directions of other sides in the circumference of the smoke pipe 2. In this embodiment, the brush roller mechanisms 3 are arranged on all four sides of the smoke pipe 2.

[0052] As Figure 2 shown, two brush roller mechanisms 3 located on opposite sides of the smoke pipe 2 form a brush roller group, and the two brush roller mechanisms 3 in the same brush roller group are located at the same height position; each brush roller group is arranged vertically in sequence.

[0053] The purpose of arranging the brush roller groups in an up-and-down manner is to avoid interference between two adjacent brush roller mechanisms 3 in the circumference. After being arranged up and down, there are no interference factors at the opposite ends of the brush roller mechanisms 3, and the brush rollers 4 can be set longer to completely cover the sides of the smoke pipe 2.

[0054] As Figure 1 shown, the cleaning structure includes an oil drip pan 8. The oil drip pan 8 is located below the smoke pipe 2, and the downward projection of the brush roller mechanism 3 falls within the oil drip pan 8.

[0055] The oil stains brushed off by the brush roller mechanism 3 and the condensed water generated after the steam condenses will both fall into the oil drip pan 8. Drain holes can be arranged on the oil drip pan 8, and the stains in the oil drip pan 8 can be transferred to the oil cup through the drain holes.

[0056] Embodiment 2

[0057] As Figure 3 shown, the difference from Embodiment 1 is that the cleaning structure includes an annular pipe body 6. The annular pipe body 6 includes an inlet 61 and an outlet 62. The inlet 61 is connected to the steam outlet 51, and the outlet 62 is arranged on the inner circumferential wall of the annular pipe body 6; the smoke pipe 2 is located within the inner ring area of the annular pipe body 6.

[0058] The brush roller mechanism 3 can be arranged on all four sides of the smoke pipe 2. In order to cover the steam around the smoke pipe 2, an annular pipe body 6 can be connected to the steam outlet 51. The annular pipe body 6 has an inlet 61 docked with the steam outlet 51, and a plurality of outlets 62 arranged in an annular pattern are provided on the inner wall of the annular pipe body 6. The outlets 62 are inclined upward and middle, and the annular pipe body 6 is located below the smoke pipe 2, and the smoke pipe 2 is located within the inner ring area of the annular pipe body 6, so that the outlets 62 can face all sides of the smoke pipe 2.

[0059] Embodiment 3

[0060] As Figure 4 shown, the cleaning structure includes a steam generator 5, and the steam generator 5 has a steam outlet 51; the difference from Embodiment 1 is that the brush roller 4 has a hollow rotating shaft 71, bristles are arranged on the circumferential outer wall of the rotating shaft 71, and through holes 72 communicating inside and outside are arranged on the circumferential side wall of the rotating shaft 71; one end of the rotating shaft 71 is connected to the driving mechanism, and the other end is docked with the steam outlet 51 through a rotary joint.

[0061] One end of the rotating shaft 71 of the brush roller 4 is connected to the steam outlet 51 through a rotary joint, and the other end is connected to the driving mechanism. Under the action of the rotating structure, the brush roller 4 can rotate relative to the steam generator 5. At the same time, the steam output from the steam outlet 51 can enter the hollow cavity of the rotating shaft 71, and then these steams pass through the through holes 72 and are ejected. The ejected steam immediately contacts the bristles, so as to form a humid and hot environment around the bristles, and the oil stains are easier to be scraped off in the humid and hot environment.

[0062] The smoking device provided by the present utility model includes the above-mentioned cleaning structure. Since the smoking device provided by the present utility model incorporates the above-mentioned cleaning structure, the smoking device provided by the present utility model also has the advantages of the cleaning structure.

[0063] As Figure 5 shown, the smoking device includes: a housing 91, a fan assembly 92, a diversion channel 93, a tabletop 1 and a smoke pipe 2; the housing 91 is located above the tabletop 1; the smoke pipe 2 is provided with a smoke inlet and a smoke outlet; the upper surface of the tabletop 1 is provided with a cooking appliance and the smoke pipe 2, and the cleaning structure can be located below the tabletop 1 ( Figure 5 not drawn in the figure).

[0064] The housing 91 is provided with a first opening 911 and a second opening 912 communicating inside and outside; the fan assembly 92 is arranged inside the housing 91, and the fan assembly 92 is used to generate an air flow flowing from the outside of the housing 91 toward the inside of the housing 91 at the first opening 911 and the second opening 912 respectively.

[0065] The upper end of the diversion channel 93 is connected to the second opening 912, and the lower end is connected to the air outlet of the smoke pipe 2. The oil fume absorbed by the smoke pipe 2 enters the housing 91 after passing through the diversion channel 93. At the same time, the first opening 911 on the housing 91 can also absorb oil fume.

[0066] The second opening 912 is the oil drainage port of the housing 91, and the smoke outlet is the oil drainage port of the smoke pipe 2, so that the oil stains in the housing 91 and the smoke pipe 2 can be discharged into the diversion channel 93; an oil leakage hole 931 communicating the inside and outside is provided on the diversion channel 93.

[0067] In addition to connecting the housing 91 and the smoke pipe 2 and forming an air passage, the diversion channel 93 can also form an oil passage for the housing 91 and the smoke pipe 2. The oil stains condensed inside the housing 91, the smoke pipe 2, and the diversion channel 93 can all be discharged from the oil leakage hole 931.

[0068] The smoking device further includes an extended oil passage 932. One end of the extended oil passage 932 is connected to the oil leakage hole 931, and the other end faces the oil cup.

[0069] The upper end of the extended oil passage 932 is connected to the oil leakage hole 931, and the lower end extends towards the oil cup, so as to be closer to the oil cup. Due to the existence of the extended oil passage 932, the pressure relief at the oil leakage hole 931 can be reduced.

[0070] A switching mechanism is provided in the diversion channel 93, and the switching mechanism is used to make the diversion channel 93 conduct or disconnect.

[0071] Specifically, the switching mechanism includes a first valve plate that can move relative to the diversion channel 93. By controlling the first valve plate, the diversion channel 93 can be disconnected, and the smoke pipe 2 will no longer work. The smoking device sucks oil fume through the first opening 911. Move the first valve plate. When the diversion channel 93 is conducting, the smoke inlet on the smoke pipe 2 and the first opening 911 suck oil fume at the same time, and the smoking range is larger.

[0072] A second valve plate for controlling the opening and closing of the oil leakage hole 931 is provided in the diversion channel 93.

[0073] The second valve plate can be arranged beside the oil leakage hole 931. When the second valve plate closes the oil leakage hole 931, the pressure relief of the oil leakage hole 931 can be completely avoided, and the pressure generated by the fan unit can be completely concentrated at the first opening 911 and the smoke inlet, improving the smoking efficiency. And when oil drainage is required, just open the second valve plate.

[0074] In this embodiment, the first valve plate and the second valve plate are the same first common valve plate 94; the first common valve plate 94 can move to the first position, the second position and the third position within the diversion channel 93; at the first position, the oil leakage hole 931 is closed by the first common valve plate 94, and the second opening 912 is communicated with the smoke pipe 2; at the second position, the first common valve plate 94 cuts off the diversion channel 93, and the smoke pipe 2 is closed; at the third position, the diversion channel 93 is communicated, and the oil leakage hole 931 is opened.

[0075] As Figure 6 shown, at the first position, the oil leakage hole 931 is closed by the first common valve plate 94, the second opening 912 is communicated with the smoke pipe 2, and the first opening 911 and the smoke inlet of the smoke pipe 2 are opened simultaneously. In this state, the oil leakage hole 931 is closed, and the negative pressure generated by the fan assembly 92 will not leak from the oil leakage hole 931. Therefore, the sum of the negative pressures acting on the first opening 911 and the smoke inlet is the largest.

[0076] As Figure 7 shown, at the second position, the first common valve plate 94 cuts off the diversion channel 93, the smoke pipe 2 is closed, and the negative pressure generated by the fan assembly 92 is mainly concentrated at the first opening 911. In this embodiment, the first common valve plate 94 is arranged between the oil leakage hole 931 and the air outlet, that is to say, when the first common valve plate 94 is in the second position, the oil leakage hole 931 and the second opening 912 can be communicated, and the oil stain in the housing 91 can be discharged normally.

[0077] In another implementable solution, the first common valve plate 94 can be arranged between the oil leakage hole 931 and the second opening 912. When the first common valve plate 94 is in the second position, the first common valve plate 94 can close the oil leakage hole 931 and the second opening 912, so as to avoid pressure relief of the oil leakage hole 931.

[0078] As Figure 8 shown, at the third position, the first common valve plate 94 can be located below the oil leakage hole 931, the diversion channel 93 is communicated, and the oil leakage hole 931 is opened. At this time, both the first opening 911 and the smoke pipe 2 can absorb oil fume, and the oil stain flowing through the diversion channel 93 will flow out from the oil leakage hole 931.

[0079] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
