Abstract

The utility model relates to a group type device which is used in situations such as public toilets, buildings and constructions, etc. and utilizes an exhaust fan to draw the air from a toilet closet in a given direction, forming a reverse wind flow for exhaustion and deodorization. In the utility model, an air outlet is arranged on the upper part of the toilet closet, a branch exhaust duct is arranged between the toilet closet and a head exhaust duct, and the exhaust fan is arranged on an outlet of the head exhaust duct. The utility model utilizes reverse wind flow to exhaust and deodorize, having favorable deodorizing effect, which can improve the ventilating performance of the toilet and adjust the air exhausting volume, having the advantages of simple structure and easy use.

Description

W.c.pan down draught stream air draft cluster odor removal

The utility model is to be used for occasions such as communal toilet, building constructions, the air in the w.c.pan is taken away the concentrating type odor removal that forms down draught stream air draft deodorizing with the exhaust blower orientation.

For these years, toilet deodorization is a troubling problem always.

No matter be in the lavatory of resident's family, or the communal toilet of public place, w.c.pan all will give out stink in use, and in use or not the time spent just more fierce by the stink that sewer pipe returns up.

The method that is used for toilet deodorization at present, a kind of deodorant that is to use, another kind are the performance of ventilating of as far as possible improveing lavatory wind.

Deodorant no matter be cleaning deodorizing class, or throw the deodorizing class, after using w.c.pan once bath along with being flushed away, thereby deodorizing effect is bad, and uses inconveniently, use cost is also than higher simultaneously.

The method of improvement lavatory ventilation effect, in building constructions, particularly effect is limited especially in resident's building, the stink that particularly comes out from w.c.pan must just can be delivered to exhaust outlet through air, thereby no matter spend much strength to go to improve the ventilation effect in lavatory, all can't eliminate the stink in lavatory at all.

The purpose of this utility model is to design a kind of in occasions such as communal toilet and building constructions, with the exhaust blower orientation air in the w.c.pan is taken away, utilizes the air that replenishes into from the w.c.pan mouth to form the concentrating type odor removal of down draught stream air draft deodorizing.

The utility model is shaped on exhaust outlet on w.c.pan top, between w.c.pan and total exhaust duct the branch exhaust duct is housed, and in total exhaust duct outlet exhaust blower is housed.

The utility model in use, by exhaust blower air guided in the w.c.pan taken away through minute exhaust duct and total exhaust duct, utilization forms down draught stream from the air that the w.c.pan mouth replenishes at the w.c.pan mouth, effectively stops the stink in the w.c.pan to distribute, the clean rooms air.

For the exhaust air rate (being the wind speed on the w.c.pan mouth) of controlling each w.c.pan, to adapt to the instructions for use of regulating the control air quantity under the various conditions such as all ages and classes, Various Seasonal, the utility model can install the air quantity valve additional on minute exhaust duct.

Compared with prior art, the utlity model has following remarkable advantage:

1. utilize down draught stream air draft deodorizing, effectively stoped the stink in the w.c.pan outwards to distribute good deodorization effect;

2. when utilizing down draught stream air draft deodorizing, can improve the performance of ventilating in lavatory;

3. simple in structure, easy to use, be easy to manufacture;

4. can regulate exhaust air rate, adapt to the instructions for use under the various conditions such as all ages and classes, Various Seasonal;

5. be specially adapted to unified ventilation in newly-built building lavatory and down draught stream air draft deodorizing.

Accompanying drawing is embodiment of the present utility model.

Accompanying drawing 1 is the general structure schematic diagram.

Below in conjunction with the embodiment of accompanying drawing, describe the utility model in detail.

1. be shaped on exhaust outlet on w.c.pan (2) top, between w.c.pan (2) and total exhaust duct (3), branch exhaust duct (5) be housed, in total exhaust duct (3) outlet, exhaust blower (1) is housed.

2. air quantity valve (4) is housed on a minute exhaust duct (5).

Claims

1. w.c.pan down draught stream air draft cluster odor removal is characterized in that: be shaped on exhaust outlet on w.c.pan (2) top, between w.c.pan (2) and total exhaust duct (3) branch exhaust duct (5) be housed, in total exhaust duct (3) outlet exhaust blower (1) is housed.
