Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a toilet system that effectively deodorizes a toilet room, and in particular uses foam for cleaning a toilet bowl.

(Prior art and its problems) Air sucked by an air pump is passed through a nozzle with many small holes, and then passed through water containing a surfactant to generate a large amount of bubbles. There are known toilet systems that flush the inside of the toilet bowl, eliminate odors by sealing bubbles, and save water by discharging water into the toilet bowl.

By the way, in such a toilet system, since bubbles are generated by a nozzle having a large number of small holes as described above, there is a problem that the small holes of the nozzle are easily clogged.

The main cause of nozzle clogging is the growth of aerobic bacteria, and the fact is that the nozzle's ability to generate bubbles deteriorates with long-term use, and the nozzle is usually replaced with a new one during maintenance.

However, although it would be good if the nozzle could be replaced in a timely manner, due to differences in usage conditions, etc., nozzles become clogged and do not perform adequately.Therefore, an effective solution is desired.

In addition, attempts have been made to solve this problem by changing the size of the nozzle hole or by mixing disinfectants or bleach into the surfactant, but these efforts have not been sufficiently effective. That is the reality.

(Means for Solving the Problems) The present invention solves the above-mentioned conventional problems, and can be achieved by the improved toilet system described below.

That is, the toilet system 1 (first
In Figure), air sucked from an air pump 2 is sent into water W containing surfactant K to generate a large amount of bubbles, and this foam is discharged into the toilet bowl 3 to clean the inside of the toilet bowl 3. In what I decided to do,
communicates with the air intake port 2a of the air pump 2,
For example, it is characterized in that a substantially sealed chamber 4 is provided within the toilet system 1, and an ozone generator 5 is disposed within this chamber 4. In addition, according to the best embodiment of the present invention, an ozone generating lamp 6 is used as the ozone generator 5, and the chamber 4 contains water Wo (and/or W) used for generating bubbles.
This includes a case where Wo (and/or W) is irradiated with light from the ozone generating lamp 6.

(effect) Next, the operation of the present invention will be explained.

First, ozone is generated by the ozone generator 5,
This ozone fills the chamber 4. Ozone in the chamber 4 is sucked in through the suction port 2a by the operation of the air pump 2, and as a result, a large amount of bubbles A enveloping ozone are generated from the water W containing the surfactant K. This foam A... is released into the toilet bowl 3, and performs functions such as cleaning the interior of the toilet bowl 3 and eliminating odors by sealing the foam, as in the conventional case.

On the other hand, the bubbles A in the toilet bowl 3 collapse over time. Therefore, the ozone contained in the collapsed bubble A is released, and this ozone diffuses into the toilet room, deodorizing the inside of the toilet room.

On the other hand, using the ozone generating lamp 6, water Wo (and/
Alternatively, when W) is irradiated with irradiation light, the ultraviolet rays from the ozone generating lamp 6 produce a sterilizing effect on the water, and the water is appropriately warmed by the amount of heat of the irradiation light, thereby exhibiting an anti-freezing effect.

At the upper end of the internal space of the unit 13 and toward the front, there is provided an air pump 2 and a surfactant supply container 15 lined up with the air pump 2.

The air pump 2 has two air output systems, one for steady use and the other for excretion. The regular output is output periodically regardless of whether the toilet is used, and the excretion output is output by the user's voluntary operation when using the toilet. Further, each of these air outputs communicates through tubes 16 and 17, respectively, to nozzles 18 and 19 arranged on the internal bottom plate. This nozzle 18,1
9 has a large number of small holes formed on its circumferential surface as described above. The air pump 2 is equipped with a suction port 2a on its rear surface, a bubble volume adjustment knob 21 on its top surface, and an operation button 22 on its side surface.

The surfactant supply container 15 is connected to the foam supply unit 13.

6 and discharged through the opening 27 into the guide ball 10 in the toilet bowl 3.

According to the present invention, an ozone generating lamp 6 is attached to the inside of the upper surface of the case 14 constituting the rear chamber section 24.
As shown in FIG. 2, the ozone generating lamp 6 is elongated in the left-right direction (the front and back directions of the page). The ozone generating lamp 6 emits ultraviolet rays, and in particular uses far ultraviolet rays (1849A°) to ozone oxygen in the air (3O ₂ → 2O ₃ ), and
Furthermore, ultraviolet rays in other wavelength ranges (2000A° ~
Sterilize using 2800A°). As such an ozone generating lamp 6, for example, "Towa Lighting Co., Ltd."
You can use “Deodolite (product name)” made by the company.

Next, an electrical system for generating ozone will be explained with reference to FIG.

A glow lamp 3 for lighting is provided between each end of the heater at both ends of the discharge tube 6a in the ozone generating lamp 6.
Connect 0. A capacitor 31 for noise prevention is connected in parallel to this glow lamp 30. Further, a bimetal 32, a temperature fuse 33, and a stabilizer 34 are connected in series between each other end of the heater at both ends, and connected to an AC plug 35 for a commercial power source. Bimetal 32 and temperature fuse 33 are ozone generating lamp 6
This is a safety device for preventing overheating caused by placing the bimetal 32 inside the sealed chamber 4.
The circuit is turned off when the temperature rises above 80°C, and the temperature fuse 33 melts when the temperature rises above 110°C. These bimetal 32 and fuse 33 are attached near the ozone generating lamp 6. Further, 36 is a pilot lamp, which is disposed on the outside surface of the unit 13 to indicate that the ozone generating lamp 6 is being lit. Note that the illustrated circuit is a basic circuit, and can also include a timer, a predetermined control circuit, etc., and can be turned on intermittently, or can be linked with the air pump 2.

Next, the overall function of the toilet system 1 will be explained.

First, by lighting the ozone generating lamp 6, surrounding acid is converted into ozone. Ozone generated thereby fills the substantially sealed chamber 4. Ozone in the chamber 4 is pumped to the suction port 2a by the operation of the air pump 2.
The air is sucked in from the inlet port 2a, moves through the air pump 2, tube 16 or 17, and nozzle 18 or 19, and is discharged from the nozzle 18 or 19 as a large amount of small bubbles. A large amount of bubbles A are generated from the surface of the water W, and the bubbles A are guided by the bubble collecting plate 26 and discharged into the toilet bowl 3.
Each of the released bubbles A encloses ozone inside. This foam A is the guide ball 1 inside the toilet bowl 3.
0, and constantly wets the guide ball 10 to make it easier for the human waste to move downward, and also cleans the guide ball 10, and collects on the rubber ring 11, forming a toilet tank due to bubble sealing. Blocks odors coming up from the sides.

By the way, what should be noted here is that the bubbles A gradually collapse inside the toilet bowl 3. As a result, when the bubble A collapses, the ozone contained inside is released into the air and diffuses into the toilet room, and deodorizes unpleasant odors and bad odors in the toilet room.

On the other hand, the light emitted from the ozone generating lamp 6 is ultraviolet rays, and this ultraviolet rays are emitted from the water Wo and W below.
is directly irradiated. In other words, the ultraviolet rays sterilize the water Wo and W. In addition, this water Wo
Since it is a water-saving toilet system, the water and W are stored in the rear chamber 24 for a relatively long time and are placed under conditions where bacteria etc. are likely to occur, but this situation can be effectively suppressed by irradiation with ultraviolet rays. It will be done.
Therefore, the ozone prevents the generation of aerobic bacteria, eliminates clogging of the nozzles 18 and 19, and ensures stable foam generation.In addition to the above-mentioned sterilizing effect, the inside of the unit 13 is always kept clean. Ru.

Further, since the ozone generating lamp 6 generates a moderate amount of heat, the water Wo and W are warmed by this heat, and freezing can be prevented during the winter. It has been confirmed that the temperatures of the waters Wo and W can be maintained at a temperature approximately 8°C to 10°C higher than the external temperature.

The above-mentioned functions are collectively shown in a flowchart in FIG.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments. For example, although an ozone generating lamp is shown as an example, any ozone generator based on another principle that does not use a discharge tube can be used if attention is focused only on the generation of ozone. Further, the chamber portion 4 may be completely sealed, or may have a slight gap. In addition, the partition plate part 2
5 may be formed transparent so that the irradiation light from the ozone generating lamp hits the water W in the front chamber part 23 more effectively. Other details such as configuration, shape, format, arrangement, quantity, etc. may be arbitrarily changed without departing from the spirit of the present invention.

(Effects of the Invention) As described above, the toilet system according to the present invention is a toilet system in which the inside of the toilet bowl is flushed by discharging foam into the toilet bowl. Since the ozone generator is installed in the toilet system and the ozone generator is placed inside the toilet system, the following remarkable effects can be obtained.

Bubbles containing ozone are released into the guide ball of the toilet bowl, and a suitable amount of ozone is diffused into the toilet room from here, making it possible to effectively deodorize the toilet room. Furthermore, there is no need to provide a separate deodorizer, which can save costs.

The inside of the toilet bowl can be kept clean by preventing the proliferation of bacteria by ozone and by the sterilizing effect of ultraviolet rays according to the best embodiment, and the nozzle for generating foam can be prevented from clogging, so that stable foam generation can be ensured at all times.

The optimal embodiment warms the water in the system appropriately, thereby preventing freezing during the winter months. Further, even when other freezing devices are used together, the device can be simplified.
