The integrated kitchen range of a kind of side-suction lower discharging type
Technical field
The utility model relates to the integrated kitchen range of a kind of side-suction lower discharging type, belongs to the improvement technology of the integrated kitchen range of side-suction lower discharging type.
Background technology
Installation site for the public flue that adapts to different occasions, integrated kitchen range product in the market often all offers air outlet in the left and right sides of casing, in order to reach this purpose, some integrated kitchen range manufacturers adopt " ⊥ " type connected mode, adopt a long
straight exhaust duct 8 that casing left and right sides air outlet is communicated with, offering air inlet in the centre position of long in
line airduct 8 links to each other with the air outlet of blower fan system, as shown in Figure 1, when concrete the installation, if the user need be from 31 air drafts of
casing 3 left side air outlets, then block right
side air outlet 32, vice versa; Though this structure is easy to operate, very big in the flow losses of corner, " ⊥ " type air channel, also can cause air quantity, blast sharply to descend simultaneously; Also have some producers on the air outlet of blower fan system, directly to connect the scalable rubber and plastic class smoke exhaust pipe that curves, turn to the demand of air draft about satisfying by its plasticity, but because the inner surface indentation of this smoke exhaust pipe, flow resistance is bigger in the pipe, especially bigger in the corner flow losses, can make air quantity, air loss bigger equally; According to measuring statistics, the wind loss of these two kinds of connected modes is up to 2
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of significantly to reduce the flow losses of fume emission, the integrated kitchen range of side-suction lower discharging type that the air draft of the flexible adaptation left and right sides requires.
The technical solution of the utility model is: the integrated kitchen range of the utility model side-suction lower discharging type, include exhaust fume collecting hood, kitchen range, casing, inlet box and blower fan system, wherein the kitchen range device is at the end face of casing, the exhaust fume collecting hood cover is contained in the back upper place of kitchen range, blower fan system is positioned at the below of kitchen range and installs at casing, its air outlet down, the inlet box device is between the rear wall of blower fan system and casing, the air inlet at inlet box top links to each other with the bottom of exhaust fume collecting hood and forms air intake passage, the air inlet of the corresponding blower fan system of the air outlet of inlet box bottom is solidly installed, it is characterized in that being provided with bend pipe at the air outlet place of blower fan system, the Way out of bend pipe is towards a left side or towards the right side.
The outlet of above-mentioned bend pipe is connected with check-valves, and check-valves is connected with smoke exhaust pipe.
Above-mentioned bend pipe includes suction flange, first side plate, second side plate, peripheral board, interior coaming plate and outlet(discharge) flange, wherein suction flange, first side plate, second side plate, peripheral board, interior coaming plate and outlet(discharge) flange seal the formation bend pipe that is solidly installed, the suction flange of bend pipe links together by screw or buckle or connected mode that both combine and the air outlet of blower fan system, and its outlet(discharge) flange links together by screw and check-valves.
The angle of turning round of above-mentioned bend pipe is φ, 90 degree≤φ≤120 degree.
The flow area of above-mentioned bend pipe is shaped as rectangle, and outlet size is consistent with inlet size, imports and exports width and is L, and corner's circular arc internal diameter is R1, and external diameter is R2, R1 〉=15mm wherein, R2 〉=R1+L.
The peripheral board of above-mentioned bend pipe, interior coaming plate weld with first side plate, second side plate respectively earlier separately, and weld with suction flange and outlet(discharge) flange respectively at two ends again.
The independent injection mo(u)lding of above-mentioned bend pipe, or with the moulding of check-valves integral molded plastic.
The utility model is owing to adopted the bend pipe air exhausting device of arc transition, can make the air-flow of corner of air exhaust passage more smooth and easy, thereby the flow losses in blower fan system exit are reduced greatly, air quantity, air loss have effectively been reduced, not only improved the discharge efficiency of flue gas, and satisfied the different requirements of user fully left and right sides air draft direction.

The specific embodiment
The utility model is described in further detail for following structure drawings and Examples.
Embodiment 1:
As Fig. 2, shown in 3, the integrated kitchen range of the utility model side-suction lower discharging type, include exhaust fume collecting hood 1, kitchen range 2, casing 3, inlet box 4 and blower fan system 5, wherein kitchen range 2 devices are at the end face of casing 3, exhaust fume collecting hood 1 cover is contained in the back upper place of kitchen range 2, blower fan system 5 is positioned at the below of kitchen range 2 and installs at casing 3, its air outlet down, inlet box 4 devices are between the rear wall of blower fan system 5 and casing 3, the air inlet at inlet box 4 tops links to each other with the bottom of exhaust fume collecting hood 1 and forms air intake passage, the air inlet of the corresponding blower fan system 5 of the air outlet of inlet box 4 bottoms is solidly installed, the air outlet place of blower fan system 5 is provided with bend pipe 6, the outlet of bend pipe 6 is connected with check-valves 7, and check-valves is connected with smoke exhaust pipe, and the Way out of bend pipe 6 is towards a left side (as Fig. 3) or towards right (as Fig. 2).
As shown in Figure 4, above-mentioned bend pipe 6 includes suction flange 62, first side plate 61, second side plate 63, peripheral board 64, interior coaming plate 65 and outlet(discharge) flange 66, wherein suction flange 62, first side plate 61, second side plate 63, peripheral board 64, interior coaming plate 65 and outlet(discharge) flange 66 sealings are solidly installed and form bend pipe 6, the suction flange 62 of bend pipe 6 links together by screw or buckle or connected mode that both combine and the air outlet of blower fan system 5, and its outlet(discharge) flange 66 links together by screw and check-valves 7.
As shown in Figure 5, the angle of turning round of above-mentioned bend pipe 6 is φ, 90 degree≤φ≤120 degree.The flow area of above-mentioned bend pipe 6 is shaped as rectangle, and outlet size is consistent with inlet size, imports and exports width and is L, and corner's circular arc internal diameter is R1, and external diameter is R2, R1 〉=15mm wherein, R2 〉=R1+L.
