JPH0571158A - Method for discharging stench from lavatory - Google Patents

Abstract

PURPOSE:To make the environment of a lavatory comfortable by connecting a discharge pipe on the way of a flush nozzle water supply pipe of a flush type stool and discharging a stench sucked from the flush nozzle through a discharge pipe to the outside. CONSTITUTION:A water supply pipe 4 for supplying water from a water tank 3 to a flush nozzle 2 provided on the upper inner periphery of a stool 1 is formed with a T-shaped branch port 5. Next, a discharge pipe 7 having a discharge fan 6 is connected to the branch port 5. Next, if necessary, a switch valve 8 is attached to a branch inlet of the branch port 5 to open the pipe 7 in discharging and close the pipe 7 in flush. In using a lavatory, the discharge fan 6 is rotated to suck a stench in the stool 1 from the nozzle 2 and discharge the stench through the pipe 7 to the outside, so that the stench and moisture in relieving oneself can be immediately removed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for exhausting odors from a toilet.

[0002]

2. Description of the Related Art The conventional method of exhausting a toilet is to provide an exhaust fan on the ceiling of the toilet to exhaust the air.

[0003]

However, in the conventional exhaust method, since the air in the toilet rises from the bottom to the top, the smell of defecation fills the inside of the toilet, which makes it very uncomfortable. Also, during the rainy season, the humidity is high, and the vapor of defecation is condensed on the hips, and the toilet paper sticks and tears, which was also a problem. The present invention provides a method for comfortably exhausting air in a toilet.

[0004]

In order to achieve the above object, the present invention does not exhaust directly from an exhaust fan on the ceiling but exhausts from a flush nozzle of a flush toilet.
As a means for this, the water tank and the water supply pipe to the toilet are branched in a T shape, and the branch port and the exhaust fan are connected by an exhaust pipe.

[0005]

[Function] Therefore, when the exhaust fan is being rotated, the air in the toilet is exhausted from the flush nozzle of the toilet bowl through the exhaust pipe,
As with conventional flushing of the toilet bowl, the water in the water storage tank is ejected from the flush nozzle through the water supply pipe.

Embodiments Embodiments will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a toilet odor exhaust method using an example of a toilet seat flush toilet. In a normal toilet seat flush toilet, a flush nozzle (2) is provided in the upper inner circumference of the toilet (1), and water is supplied from a water storage tank (3) through a water supply pipe (4).
In the present invention, a branch port (5) is provided by branching the middle of the water supply pipe into a T shape, and the branch port and the exhaust fan (6) are connected to the exhaust pipe (7).
Connect with. An opening / closing valve (8) may be provided at the boundary of the T-shaped branch as required. The on-off valve communicates with the exhaust pipe when exhausted by the action of a spring or the like, and closes the on-off valve with water pressure when using water. Figure 2 shows an example of a water tank directly on the toilet seat flush toilet.
If the water supply pipe to the flush nozzle is not exposed to the outside,
The toilet bowl is provided with a branch groove (10) communicating with the water supply groove (9) in the toilet bowl, and the exhaust pipe (11) is connected thereto. The present invention is also applicable to all flush toilets that are not toilet seat types. In the present invention, the flush nose is used also as the exhaust hole, but the idea is the same in that even if the flush nozzle is provided with an exhaust hole separately from the flush nozzle, air is exhausted from the toilet.

[0007]

As described above, according to the present invention, since the odor is sucked into the toilet bowl, the scent of defecation does not stay in the toilet and steam is not condensed on the buttocks, which is very comfortable. ..
