Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement of a simple flush toilet device configured to be able to discharge waste with a small flow of flushing water.

[Prior art]

Application was made in 1984 as a conventional simple flush toilet device.
There is one as described in the specification of No. 194626 (Japanese Utility Model Publication No. 103275/1983). This system has an opening/closing lid with a breathable top plate attached to the bottom opening of the bowl, and uses compressed air to clean dirt on the top plate by generating air bubbles from the water lubricating the top plate, thereby cleaning the bowl surface. This is done by injecting washing water from the rim water passage.

However, since the bowl is simply washed by flushing water, a considerable flow rate is required to sufficiently remove and wash away the dirt, which is inconvenient for a simple flush toilet.

[Purpose of invention]

The purpose of the present invention is to generate air bubbles to remove dirt from the bowl using pressurized air, so that waste can be removed with a small flow of flushing water, thereby keeping the toilet bowl clean.

[Structure of the idea]

The configuration of the present invention includes a washing water supply system for washing,
In a simple flush toilet device that has a compressed air supply system for generating air bubbles and an opening/closing lid drive system for operating the opening/closing lid, the rim part at the upper end of the toilet body communicates with the discharge port and the inner surface of the toilet body. A ventilated bowl defining a sealed space is installed, and compressed air from a compressed air supply system is supplied to the sealed space and a ventilated top plate portion attached to the opening/closing lid.

〔Example〕

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a side sectional view of a simple flush toilet device according to the present invention, and FIG. 2 is a sectional view taken along the - line arrow in FIG. 1.

In the figure, 1 is a toilet main body made of a non-ventilated material such as ceramics, 2 is a housing that stands on the rear side of the toilet main body 1 and has a wash water tank 3 built into the upper part, and 4 is a rim part of the toilet main body 1. 5. It is rotatably attached to the top surface and is a toilet seat. A rim water passage 6 is formed around the entire periphery of the rim portion 5 and communicates with the cleaning water tank 3 via a water supply chamber 6a, and a water supply pump P serving as a water supply device is connected to this communication passage.
is provided. Washing water flowing down the rim passageway 6 is discharged toward the bowl 8 from water injection holes 7 opened at required pitches.

The bowl 8 is formed into a mortar shape by an air permeable plate, has a flange 9 formed at the lower end, and is fixed to the toilet main body 1 by interposing a packing 11 into a bolt 10 embedded in the flange 9 and screwing a nut 12 together. has been done. The upper edge 8a of the bowl 8 is arranged to abut the lower edge 5a of the rim portion 5, and is hermetically sealed and joined with the adhesive sealant 13.

As shown in the figure, there is a space between the toilet main body 1 and the bowl 8.
A sealed space S is formed around the entire outer surface of the bowl 8, and the sealed space S is configured as a pressure chamber 14 that pressurizes the bowl 8 from the outside. This pressure chamber 14
is connected through a supply pipe 15 to a compressor C forming an air supply device provided in the housing 2, and compressed air from the compressor C can be supplied to the outside of the bowl 8.

Reference numeral 16 denotes an opening/closing lid for opening and closing the discharge port 1a at the lower end of the toilet main body 1, which includes a base plate 18 pivoted to a pivot 17, a gasket 19 that comes into contact with and separates from the end surface of the discharge port 1a, and a base plate 1.
8 and a breathable top plate 21 disposed with a cavity 20 between them. A flexible hose 22 is connected to the compressor C between the base plate 18 and the compressor C, and can supply compressed air into the cavity 20.

The opening/closing drive of the opening/closing lid 16 is similar to that described in the specification of Utility Model Application No. 194626/1983 mentioned in the conventional example, and the rotational movement of the wheel W of the drive motor M forming the opening/closing drive mechanism is controlled by the link mechanism L. This is done by

The compressor C, the water supply pump P, and the drive motor M are each linked to each other, and once an operation switch (not shown) is pressed, the control system performs operations from the start of cleaning to the end of the opening/closing operation of the opening/closing lid 16.

FIG. 3 is an example of an operation time chart. When the operation switch is turned on, the water supply pump P and compressor are activated, and cleaning water is discharged from the water injection hole 7 of the rim passageway 6 into the bowl 8, and the pressure chamber 14 and the opening/closing lid are activated. 1
Compressed air is supplied into the cavity 20 of No.6.

The cleaning water should be enough to wet the surface of the bowl 8,
A low flow rate of several hundred cc per time is sufficient. In addition to ordinary clean water and gray water, the most suitable washing water is one containing an aromatic disinfectant or a surfactant.

Washing water is supplied for a certain period of time to the bowl 8 and the opening/closing lid 1.
The top plate 21 of No. 6 is kept in a warm state, and when compressed air flows out from the pressure chamber 14 and cavity 20 into the bowl 8, air bubbles are generated on the surface side of the bowl 8 and the top plate 21. Due to the generation of air bubbles, the bowl 8
Dirt adhering to the surface peels off and falls onto the opening/closing lid 16.

After a further predetermined period of time has elapsed, the drive motor M is operated by the timer, and the opening/closing lid 16 is moved at the arrow A in FIG.
The top plate 21 is opened in the direction shown in FIG. Compressed air is supplied from the compressor C even while the opening/closing lid 16 is in operation, promoting the generation of air bubbles and facilitating the removal of dirt from the surface of the top plate 21.

Then, when the opening/closing lid 16 is closed again, the compressor C also stops, completing one cycle.

Figure 4 is another time chart, this is toilet seat 4
A weight-sensing switch (not shown) is installed in the seat, and the control system detects when a person is seated on the seat and performs cleaning during and after using the toilet.
In the same time chart, when a person is seated, a weight sensing switch is turned on, a water supply pump P and a compressor C are operated, and air bubbles are generated from the surfaces of the bowl 8 and the top plate 21 while the person is using the toilet. Next, when the person leaves after using the toilet, the weight sensing switch is turned off, and in response to this signal, a small amount of washing water is supplied again by the water supply pump P to further promote the generation of bubbles, and at the same time, the opening/closing of the opening/closing lid 16 is activated. This is the process of discharging filth.

In this time chart, air bubbles are constantly generated even when using the toilet, so the waste water is collected in a breathable bowl 8.
can be prevented from entering the pressure chamber 14.

In any operating state, bubbles for removing dirt are generated from the surface of the bowl 8, so only the amount of cleaning water required for the bubbles is sufficient, and the flow rate can be reduced.

〔effect〕

This invention can also generate air bubbles from the bowl that serve to remove dirt, so the flow rate can be smaller than when cleaning water is normally supplied to the bowl surface.
This has the effect of improving water conservation.
