Abstract

The utility model relates to an odourless water closet with an air sucking device, which comprises a closet body, a closet cover, a water tank and a flushing water device, wherein the circumferential wall on the upper part of the closet body is provided with a hollow cavity which extends to an air sucking opening and a plurality of ventilating holes which are communicated with the hollow cavity are arranged on the upper part of the inner wall surrounding the closet. When people shit, the odour generated by feces can be directly sucked away by an air sucking system, so that the indoor air of toilets is avoided being polluted, the up time of an indoor ordinary air sucking machine of toilets can be reduced, and a large-power air sucking machine is got rid of. The utility model has the characteristics of energy saving and environmental protection.

Description

No deodorizing closet

Technical field

The utility model relates to toilet, more specifically is a kind of no deodorizing closet with extractor fan.

Background technology

Existing toilet mainly contains two kinds of spray rotation flushing type and direct-flushings, all there is a common shortcoming in all types of toilets: go to toilet when defecating the people, having foul smell overflows, the hot foul smell that stool produces can be covered with the lavatory very soon, though extractor fan is arranged in the lavatory, but still to have greatly after an action of the bowels in the quite a while lavatory be odorous.

Summary of the invention

The utility model purpose is the defective that overcomes existing toilet, the not past indoor no deodorizing closet that emits foul smell when providing a kind of people to go to toilet stool.

The utility model is realized in the following way: no deodorizing closet, comprise nightstool body, closestool cover, water tank, flushometer, on nightstool body top loop perisporium, cavity is arranged, this cavity extends to suction opeing, and the top of inwall has many gravity vents to communicate with cavity in toilet ring week.

Generally speaking, the suction opeing of toilet directly can be connected the ventilation stack of wall, the hot foul smell that produces when the people goes to toilet rises.The meeting nature enters the ventilation stack of wall.Desirable installment state is the external air draft pipe of the suction opeing of toilet, and this air draft pipe is guided to the ventilation stack of wall, connects a small-sized induced draft fan or extractor fan at the end of air draft pipe.

If toilet adopts direct-flushing, above-mentioned exhausting cavity can be designed inside separately at nightstool body top loop perisporium; If toilet adopts spray rotary, exhausting cavity of the present utility model can design together with spray water channel cavity, offer an exhausting outlet separately, but need when installing air draft pipe is connected with the exhausting exit seal, and the outlet of air draft pipe is guided to the wall ventilation stack at indoor top, the end of air draft pipe still can be installed small-sized induced draft fan, and like this when water-closet bowl flushing, the action of gravity of water makes it can be along the air draft pipe adverse current.

Above-mentioned small-sized induced draft fan is actually a small-sized air draft electric fan (perhaps being the exhausting electric fan), the power switch of this electric fan can be arranged to infra-red sensor switch, and like this, exhaust fan just started exhausting when the someone entered the lavatory, and electric fan stops exhausting when leaving.

The beneficial effects of the utility model are: because the utility model is that more common toilet has increased extractor fan, can make the people when going to toilet stool, foul smell is directly taken away, can not pollute the indoor air in lavatory, in addition, can exempt the high-power exhaust fan in the lavatory, perhaps can reduce the working time of high-power exhaust fan, play purpose of energy saving.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the plan structure schematic diagram of the utility model embodiment

Fig. 2 is the side-looking structural representation of the utility model embodiment.

Among the figure, 1. nightstool body, 2. water tank, 3. cavity, 4. suction opeing, 5. gravity vent.

Specific embodiment

See Fig. 1 and Tu.In the present embodiment, comprise nightstool body (1), closestool cover (omitting among the figure), water tank (2), flushometer (omitting among the figure), on nightstool body (1) top loop perisporium, cavity (3) is arranged, this cavity extends to the suction opeing (4) of water tank (2) back, and the top of inwall has many gravity vents (5) to communicate with cavity (4) in toilet ring week.During work, the foul smell in the toilet enters cavity (4) along above-mentioned gravity vent (5), arrives suction opeing (4) again, enters the interior ventilation stack emptying of wall by air draft pipe and small-sized induced draft fan (or fan).

Claims (3)

1. there is not deodorizing closet, comprise nightstool body, closestool cover, water tank, flushometer, it is characterized in that on nightstool body top loop perisporium cavity being arranged, this cavity extends to suction opeing, and the top of inwall has many gravity vents to communicate with cavity in toilet ring week.

2. no deodorizing closet as claimed in claim 1 is characterized in that external air draft pipe of suction opeing and small-sized induced draft fan.

3. no deodorizing closet as claimed in claim 2 is characterized in that described induced draft fan power switch has infrared inductor.
