Description

[Detailed Description of the Invention] The present invention relates to measures to prevent condensation in a toilet caused by moisture from the bathroom.

Many apartment buildings are equipped with exhaust equipment in which an exhaust pipe in a bathroom is connected to an exhaust pipe in a toilet, and an exhaust fan is installed in the exhaust pipe downstream of this connection. This is intended to reduce costs by using one fan for exhausting air from the bathroom (for removing moisture) and for exhausting from the toilet (for removing odors). However, this exhaust system had the disadvantage that dew condensation would occur in the toilet unless the exhaust fan was kept running for a considerable period of time after taking a bath.

In other words, if you stop the exhaust fan immediately after taking a bath, warm, humid air from the bathroom will rise into the exhaust pipe, but the stationary fan will act as a barrier and prevent it from moving outdoors. , backflows down the exhaust pipe and into the toilet. Since the space inside the toilet is small, it becomes saturated with moisture, and dew condenses on the surfaces of the flush tank, water pipes, and walls.

Additionally, the provided toilet paper became damp, making it uncomfortable to use.

The purpose of the present invention is to solve the above-mentioned problems in the exhaust equipment by adding a simple structure, and in particular to effectively prevent condensation from existing equipment. The present invention is characterized in that a moisture-absorbing filter in which a large number of small channels are formed in a honeycomb shape using a highly hygroscopic material is attached to the exhaust pipe of the toilet in the above-mentioned exhaust equipment.

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figure 1 shows the exhaust air in an apartment complex, etc., in which an exhaust pipe 1 of a bathroom A and an exhaust pipe 2 of a toilet B are connected, and an exhaust fan G is installed in the middle of the exhaust pipe 3 downstream from this connection. Show equipment.

In the exhaust pipe 2 of the toilet B of such exhaust equipment,
A moisture absorption filter F, which will be described later, is provided.
Note that 4 indicates a ceiling slab and 5 indicates a ceiling finishing material.

As shown in FIG. 2, the moisture absorbing filter F has a large number of small channels a...
is formed into a honeycomb shape (the cross-sectional shape of the small flow passages a does not matter), and is housed inside a hard cylinder 6 to form a unit.

The cylindrical body 6 has a slightly smaller diameter than the vertical pipe portion 2a of the exhaust pipe 2 of the toilet B, and is provided with elastically deformable hooks 7 on its circumference, and is attached to the vertical pipe portion 2a. With the attached exhaust port 8 removed, the vertical pipe portion 2a
The hooks 7 are flexibly deformed in the attached state, and are frictionally engaged with the inner surface of the pipe portion 2a to prevent them from falling off downward. It's summery. In addition, 9 in the figure is a handle for extraction.

According to the above configuration, when the fan C is stopped immediately after taking a bath, the moist air in the bathroom A flows into the toilet B via the pipes 1 and 2 and the moisture absorption filter F. When passing through F, the humid air comes into contact with the channel wall surface of the hygroscopic material, which has an extremely large area and has a large number of small channels a... formed in a honeycomb shape, and through this contact, Most of the moisture in the air is filter F.
As a result, only the dehumidified air flows into toilet B, effectively preventing condensation in toilet B caused by moisture from bathroom A and dampening of toilet paper. can do.

Now, the flow of air from bathroom A into toilet B is completed within a short time after taking a bath, and compared to the limited number of baths, toilet B is used extremely frequently. Therefore, every time this toilet B is used, the air inside the toilet passes through the moisture absorption filter F.
At this time, the moisture absorbed by the filter F is evaporated by the contact of the air with the wall surface of the flow path, and the moisture absorbing filter F can be forced to dry by the exhaust air when using the toilet. can.

That is, the moisture absorbing filter F can be regenerated by toilet exhaust without any modification, and running costs are completely unnecessary.

In FIG. 2, the small channels a are shown as having a rectangular shape, but they may also be configured in a circular, polygonal, or hexagonal honeycomb shape.

Further, as the highly hygroscopic material constituting the hygroscopic filter F, it is possible to use paper, cloth, or the like carrying a hygroscopic agent, a hygroscopic agent molded into a honeycomb shape, and various other forms.

As described above, according to the present invention, even if the exhaust fan is stopped immediately after taking a bath, the moisture from the bathroom is absorbed by the filter, which prevents condensation in the toilet due to moisture from the bathroom and the toilet. Effectively prevents paper from becoming damp.

Furthermore, the filter can be regenerated by the exhaust air from frequently used toilets, making running costs completely unnecessary.

Furthermore, since the structure is as simple as attaching the moisture absorption filter to the exhaust pipe of the toilet, even when applying it to existing equipment, there is no need to make large-scale installations such as drilling a through hole in a concrete wall to add an exhaust pipe. No construction work is required, and it is very effective as a measure to prevent condensation on existing equipment.
