Abstract
The utility model discloses a negative-pressure exhaust passage shared by high-low kitchen and bath, and belongs to the technique of civil construction. The negative-pressure exhaust passage is characterized in that a lower exhaust hole is formed in the side wall of lower side part of an exhaust passage body and formed below an upper exhaust hole, a lower non-return valve is assembled in the lower exhaust hole, a lower variable-pressure flow guide body is arranged on the inner wall surface at the lower side part of the exhaust passage body, the inner end part of the lower non-return valve is covered and shielded by the lower variable-pressure flow guide body, and a lower air outlet hole is formed in the upper end part of the lower variable-pressure flow guide body. The exhaust passage disclosed by the utility model is simple and reasonable in structure, high in exhaust efficiency, good in working quality, reliable to use, and strong in practicability.
Description
Technical field
The utility model belongs to the building building technology field, relates generally to negative pressure exhaust road product equipped in a kind of dwelling house, kitchen and the washroom.
Background technology
Exhaust duct body in traditional dwelling house, kitchen and the washroom all adopts high-order exhaust structure, namely offers steam vent at exhaust duct body upper lateral part sidewall, and is equipped with wind guide component in the exhaust duct body, has tentatively realized degassing function.Along with the Chinese people local-style dwelling houses is lived the raising of condition and quality of life, and the continual renovation of residential equipment, the exhaust standard-required is improved.In recent years, a kind of high low level shares exhaust duct and begins research and development, still, owing to the defective of structure design, not only destroyed the function of original single high-order exhaust system, and owing in the exhaust duct body, form zone of positive pressure, cause gas cigarette refluence phenomenon, lost scavenging action.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, and in conjunction with the actual needs of resident living, design provides a kind of high low level of residential kitchen and toilet of new construction to share the negative pressure exhaust road, reaches raising degassing function and effect, service-strong purpose.
Basic design of the present utility model is, the high low level of residential kitchen and toilet shares the negative pressure exhaust road and comprises the exhaust duct body, at the equipped rainproof blast cap of self-action of exhaust duct body top ends, be provided with upper air-vent at exhaust duct body upper lateral part sidewall, last check (non-return) valve is fitted in the upper air-vent, install the transformation baffle in exhaust duct body upper lateral part interior sidewall surface, described upward transformation baffle will be gone up the covering of check (non-return) valve inner end and block, and be provided with venthole in last transformation baffle upper end; On the sidewall of exhaust duct body following side, be positioned at upper air-vent lower portion place and offer down steam vent, following check (non-return) valve is fitted in down in the steam vent, transformation baffle under exhaust duct body following side interior sidewall surface is installed, described transformation baffle down will descend the check (non-return) valve inner end to cover and block, be provided with lower production well in following transformation baffle upper end.
The utility model adopts in steam vent down equipped check (non-return) valve down and the equipped following transformation baffle structure that cooperatively interacts with it in the exhaust duct body, having improved the exhaust duct body at the rainproof blast cap of self-action extricates oneself under the power effect, accelerated the flow velocity that gas is discharged, and eliminate with effective entering with flue gas of external gas of prevention and pour in down a chimney the channelling phenomenon, guaranteed the cleaning of premises air, improved dwelling environment, have rational in infrastructure simple, exhaust efficiency is high, operation quality good, it is reliable, practical to use, characteristics environment-protecting clean.
Description of drawings
Fig. 1 is that the high low level of residential kitchen and toilet shares negative pressure exhaust road general structure schematic diagram;
Fig. 2 is upper and lower transformation baffle structure enlarged drawing among Fig. 1.
Piece number explanation among the figure:
1, the rainproof blast cap of self-action, 2, go up transformation baffle, 3, go up check (non-return) valve, 4, upper air-vent, 5, exhaust duct body, 6, down transformation baffle, 7, down check (non-return) valve, 8, down steam vent, 9, lower production well, 10, go up venthole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The high low level of a kind of residential kitchen and toilet shares the negative pressure exhaust road and comprises exhaust duct body 5, at the equipped rainproof blast cap 1 of self-action of exhaust duct body 5 top ends, be provided with upper air-vent 4 at exhaust duct body 5 upper lateral part sidewalls, last check (non-return) valve 3 is fitted in the upper air-vent 4, install transformation baffle 2 in exhaust duct body 5 upper lateral part interior sidewall surface, described upward transformation baffle 2 will be gone up the covering of check (non-return) valve 3 inner ends and block, and be provided with venthole 10 in last transformation baffle 2 upper ends; On exhaust duct body 5 following side sidewalls, be positioned at upper air-vent 4 lower portion places and offer down steam vent 8, following check (non-return) valve 7 is fitted in down in the steam vent 8, transformation baffle 6 under exhaust duct body 5 following side interior sidewall surface are installed, described transformation baffle 6 down will descend check (non-return) valve 7 inner ends to cover and block, be provided with lower production well 9 in following transformation baffle 6 upper ends.Described upper and lower transformation baffle 2,6 side wall upper part are to the inboard incline structure of body cavity.
During operation, under rainproof blast cap 1 effect of self-action, in exhaust duct body 5, form negative pressure, air in dwelling house, kitchen or the washroom or flue gas are opened upper and lower check (non-return) valve 3,7 and are entered in the upper and lower transformation baffle 2,6, under upper and lower transformation baffle 2,6 is controlled to the upper portion side wall guiding of the inboard inclination of body cavity, upper and lower venthole 10,9 places that air or flue gas are accelerated the portion from it of flow velocity enter in the exhaust duct body 5, drain in the atmosphere from the rainproof blast cap 1 of self-action.When the air in the atmosphere flow backwards in dwelling house, kitchen, the washroom, the air-flow of refluence was closed upper and lower check (non-return) valve 3,7 automatically, avoided flue gas to invade.
