Abstract
The utility model discloses a flow guiding type ventilation duct for kitchen or toilet. The lower end of the draft tube in the auxiliary air duct is provided with a frustum cap which forms a fume surge chamber with the baffle equipped on the lower part. A back valve is arranged on the clamp which positions on the position of the fume surge chamber. The utility model has the advantages of little resistance, fluent air exhaust, non air curtain, non blocking spiral vortex reflux back flow, and non tainting by odour.
Description
Technical field
A kind of family expenses ventilation installation of the utility model is a kind of flow-guiding type kitchen, toilet ventilation road specifically.
Background technology
Along with the improvement of urban residential environment, more and more pay attention to for the ventilating problem of family kitchen, washroom discharging smoke smell, thereby the ventilation stack of environment-friendly type is the problem of research always.The ventilation stack of present architectural use generally all is a cement square groove ventilation stack prefabricated when utilizing building operations, or utilize the ventilation stack that setting exposes on the body of wall, this ventilation stack is divided into major and minor air channel, by in its secondary air channel mozzle being set, introduce in the main air duct for the transformation pipe upper end of this mozzle, be positioned on the main air duct on the corresponding top of transformation pipe variable-pressure plate is housed, and the bottom of mozzle communicates with fume pipe.Above-mentioned ventilation solution has determined to play good ventilation effect under the normal situation of natural wind wind direction.There is following defective but this design is also corresponding: the one, the mozzle that is provided with in the secondary air channel directly with towards indoor fume pipe is connected.And the angle in square air channel is easy to produce the backflow vortex, makes kitchen, washroom occur that gas pours in down a chimney, taint of odour, causes secondary pollution; The 2nd, the gas that fume pipe is discharged acts on and also occurs pouring in down a chimney phenomenon on the secondary air channel easily; The 3rd, be positioned at the variable-pressure plate on transformation pipe top, because of fixedly installing, can not regulate the hole of smoke evacuation pore on its main air duct, and this smoke evacuation gap is a predetermined fixed, does not possess adjustability.
The utility model content
The purpose of this utility model is to provide a kind of flow-guiding type kitchen, toilet ventilation road, can effectively avoid gas to pour in down a chimney phenomenon, has eliminated secondary pollution.
For achieving the above object, technical solution of the present utility model is finished by following measure: a kind of flow-guiding type kitchen, toilet ventilation road, it is that a frustum cap is set in the mozzle lower end, and the flue gas surge chamber that the space between the dividing plate that is provided with in the secondary air channel of its underpart forms is positioned on the clamp at smoke chamber position unidirectional non retern valve is housed.
Aforesaid non retern valve is to be certain inclination angle mutually by some hinged retaining boards to be formed by stacking.
In addition, the variable-pressure plate of She Zhiing is to establish a hinge by the lower end of variable-pressure plate as mentioned above, and the adjustable variable-pressure plate of the pull bar formation in secondary air channel is passed in its upper end hinged one.
The good effect that the utlity model has is: played the buffering depressurization owing to designed the flue gas that the flue gas surge chamber enters blower fan in the ventilation stack, also greasy dirt moisture content there is deposition simultaneously, opening clamp can clear up, and has reduced the delay of greasy dirt, guarantees the flue gas smoothness of discharging; 2, in addition, also adopt and be provided with non retern valve, the retardance vortex refluxes and pours in down a chimney, and air tight, not taint of odour 3, this variable-pressure plate are adjustable structures, change the bore of main air duct according to natural wind, to increase pressure, improve the flow velocity of gas, avoid occurring negative pressure appearance 4, set up dividing plate in secondary air channel, can control the connection between each floor ventilation stack, avoid ganging up of gas.
Description of drawings
Fig. 1 is this novel structural profile schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, to this novel being further described.
By flow-guiding type kitchen shown in Figure 1, toilet ventilation road, it is to adopt the prefabricated one-tenth of GRC to have the main air duct 1 and the secondary air channel 7 of two cavitys, and this main air duct 1 is a square body, and the size in its cross section is decided according to story height.In the secondary air channel 7 of every floor, be provided with circular housing 2 mozzles 2 and should select smooth inner wall tube.The upper end of this mozzle 2 is that the transformation pipe 3 of reducing is introduced in the main air duct 1, by transformation pipe 3, flow velocity quickening, the pressure of gas is increased, and reduces negative pressure to occur, increases the main air duct draft.And the lower end of mozzle 2 connects a frustum cap 13, sealing between the bottom of this frustum cap 13 and the secondary air channel 7, in cavity, be provided with the dividing plate 12 that prevents that each floor from communicating corresponding to secondary air channel 7, the space of frustum cap 13 bottoms, make the space between its frustum cap 13 and the dividing plate form a flue gas surge chamber 8, its effect is that the flue gas that the minimizing blower fan enters cushions step-down, also has deposition simultaneously, easy cleaning to greasy dirt moisture content.Position at flue gas surge chamber 8 is provided with a clamp 10 by sealing, and a end on it is installed smoke exhaust pipe 9, is provided with at the other end that is positioned at flue gas surge chamber 8 inner clamps 9 to be used to the non retern valve 11 that prevents that gas from pouring in down a chimney.This non retern valve 11 is to be certain inclination angle each other by some hinged retaining boards to be formed by stacking.On the wall of the main air duct 1 that is positioned at transformation pipe 3 top correspondences, be provided with adjustable variable-pressure plate 4.This is adjustable, and variable-pressure plate 4 is by the lower end of the variable-pressure plate that equates with main air duct 1 inner chamber one hinge 6 is set and is connected with main air duct 1 inwall, and hinged one pull bar 5 that passes secondary air channel 7 constitutes in the upper end of its variable-pressure plate.The effect of this is adjustable variable-pressure plate 4 is by adjusting flow area, improving gas flow rate and increase draft.
In addition, aforesaid adjustable variable-pressure plate is arranged on a side of main air duct, and can regulate, and in addition also can be chosen in fixing variable-pressure plate is set on the same position, or in its both sides variable-pressure plate is set and all can satisfy instructions for use.
Claims (3)
1, flow-guiding type kitchen, toilet ventilation road, comprise major and minor air channel, in its secondary air channel, mozzle is set, the transformation pipe on this water conservancy diversion top is introduced in the main air duct, the main air duct on corresponding transformation pipe top is provided with variable-pressure plate, it is characterized in that it has in mozzle (2) lower end is provided with a frustum cap (13), and the flue gas surge chamber (8) that the space between the dividing plate (12) that the secondary air channel (7) that is positioned at its underpart is provided with forms is positioned on the clamp (10) at flue gas surge chamber (8) position unidirectional non retern valve (11) is housed.
