Description

The present invention relates to a suction type toilet bowl.

Regarding commonly used toilet bowls, although the functionality of the toilet bowl itself has evolved, the current water saving function has reached its limit.

In order to further improve the water-saving function, it is becoming necessary to reconsider the structure of the toilet bowl itself. In particular, it is necessary to use new power to carry out drainage work, rather than relying solely on water power.

The content disclosed in Patent Document 1 and other similar products (mainly recent toilet bowls with a wide water storage surface, especially those without a water storage tank) differ from conventional products (flush-down toilet bowls with a narrow water storage surface), and the water storage tank This article explains how to drain the water in the bowl using hydraulic power, using the amount of water in the bowl and some new water supply. Therefore, with the current configuration, no further water saving measures can be expected. In toilet bowls with a wide water storage surface, the amount of water stored in the bowl doubles as a water storage tank.

A toilet bowl similar to Patent Document 1 (a toilet bowl with a wide water storage surface and the water in the bowl itself also serving as a water storage tank) has a high water level in the bowl, unlike flush-type toilet bowls with a narrow water storage surface. Even when using the toilet while seated, droplets and other dirt are particularly noticeable around the back of the toilet seat. In a sense, this condition is caused by a large amount of accumulated water.

Japanese Patent Application Publication No. 08-060730

As mentioned above, the functions of the commonly used toilet bowls themselves have been evolving, but the current water saving function has reached its limit.

The present invention has been made in view of the above-mentioned problems, and it is possible to further improve the water saving function by performing drainage work that utilizes suction power, in addition to the current drainage work that relies on running water. The purpose is to maintain cleanliness for a long period of time as well as for application.

In order to solve the above-mentioned problem, a toilet bowl is provided in which the suction device and the suction port are installed around the S-shaped trap of the sewage drain pipe, and the suction device not only drains water by water power but also uses the suction device. It can drain filth and sewage with suction power. In detail, as shown in Figures 2 to 4, in addition to installing the suction device and the suction port around the S-trap, there is also a toilet that opens and closes the inside of the pipe at the bottom of the sewage drain pipe. It is characterized by the installation of a flapper valve. Regarding the suction device, it is preferable to install a suction device that uses a motor and fan used in vacuum cleaners with high suction capacity, a pump that uses a vacuum function, or a suction device used in dust collectors. . Regarding the installation location of the suction device, it is desirable to install it in the positions shown in FIGS. 2 to 4, but depending on the case, it is also possible to install it outside the toilet bowl (outside the vicinity of the S-shaped trap). Moreover, the air discharged from the suction machine is discharged from the suction machine to the waste water drain pipe through the exhaust pipe for air supply.

In the present invention, since the suction device is installed, the suction power can be used mainly to quickly exhaust the odor after use to the outside, and it can also be used to periodically remove the odor from the room. Not only can ventilation and dehumidification be performed in the same way, but the noise generated during water supply work and ventilation work can also be shortened and suppressed. In detail, an outside air intake port is installed around the toilet bowl, and a plurality of pipes are provided to connect the outside air intake port and the suction device. The suction type toilet according to claim 1 or 2, characterized in that the exhaust pipe for supplying air to be discharged to a wastewater drain pipe is installed.

In the present invention, the liquid detergent, the detergent tank for storing the liquid detergent, the liquid sending pipe for directly feeding the liquid detergent from the detergent tank into the water reservoir surface of the toilet bowl or into the water supply pipe, and the liquid detergent containing the liquid detergent are provided. A device (hereinafter referred to as a foam film generator) that generates a foam film layer by vibrating the inside of an aqueous solution is installed. In detail, as shown in Figures 1 and 2, the detergent tank, the liquid supply pipe, and the vibrating device are installed to produce a foam film layer on the water surface before using the toilet. The suction type toilet according to claim 1 or 2 is desirable. Regarding devices that vibrate, there are methods such as small vibrators used in electric toothbrushes and mobile phones, stirrer-type beer formers, etc., which are installed directly into the water volume, or the outside of the water volume of a toilet bowl. A desirable method is to install a vibrating device (outside the toilet bowl) and generate a foam film layer through conduction vibration. In addition, when installing the vibrating device directly within the volume of water stored, it is safe to install it near the tip of the vertical groove where there is less dirt and grime as shown in Figures 1 and 2 (generally only for small water). ).

In the present invention, firstly, by saving water through suction power, the water storage surface and volume are significantly reduced compared to existing products, and by changing the shape of the toilet bowl, new measures are taken to prevent the adhesion of filth and other dirt. need to be done. In detail, the suction type toilet bowl according to claim 1 or 2, characterized in that a vertical groove as shown in FIG. 1, FIG. 2, or FIG. 5 is installed around the drain port. is desirable. In particular, by installing the bubble film generating device mentioned in paragraph number 0011, the odor generated from filth and sewage is suppressed, the sound during use is suppressed, and the height of the water surface is close to the distance from the toilet seat. Unlike the above-mentioned flushable toilet bowls with a narrow water surface and no vertical grooves, the adhesion of filth and other dirt can be prevented by using materials other than the material of the toilet bowl (the coating on the toilet bowl itself). . In addition, because the water storage surface is narrower than that of a toilet bowl, where the water in the bowl itself doubles as a water storage tank, a thick foam membrane layer is maintained over a long period of time (the vibrating device is activated before using the toilet). (by doing so), it can play a role in preventing dirt and droplets from adhering even when the seat is used while seated.

The effect of the present invention is that, unlike flush-type toilet bowls with a water storage tank and a narrow water storage surface, or toilet bowls with a wide water storage surface and a bowl in which the water itself doubles as a water storage tank, the water saving ability is further improved. be effective. Existing products mainly perform drainage work using flowing water power, but in this case, the suction power of the suction machine is used as the main power, so the amount of water used for drainage work (including the volume of accumulated water) can be reduced. .

As described in paragraph number 0013, the size of the water storage tank itself can be reduced or the tank can be made unnecessary.

Some of the existing products have small fans installed around the toilet bowl, and some of them are installed as deodorizing functions, but in this case, filth etc. are installed around the source of the odor. Since the suction machine is installed to suck up solids and liquids such as sewage, the suction machine can also be used for deodorizing and ventilation functions. This has the effect that deodorization and ventilation can be performed in a short time. In addition, existing products mainly use ventilation fans, but this one is also installed in a completely different position from the ventilation fans installed around the ceiling, so it can be expected to be useful in terms of operation rate. However, in order to utilize the ability of the suction device, it may not be possible to use it at the same time as emptying the toilet after using the toilet (in cases where the suction ability is significantly reduced).

By using the above-mentioned suction machine for deodorizing and ventilation functions, it is a problem that exists especially in buildings with high floors, but since many properties do not have ventilation windows in the toilets themselves, ventilation fans can be used constantly or periodically. If the room is not properly ventilated, mold and bacteria may grow due to humidity, and dust may enter the room when people come in and out of the room. As stated in paragraph number 0015, this case has the effect of being able to remove moisture, dust, etc. in addition to paragraph number 0015, because the suction capacity is higher than that of a ventilation fan and the installation location is close to the odor source. . In the case of existing toilets, including paragraph number 0015, they currently rely only on basic ventilation fans, and this has the effect of reducing the operating rate (load) of the ventilation fans and increasing new options. This project is ideal for high-rise buildings where ventilation windows cannot be installed.

The shape of the toilet bowl in this case is intermediate between a flushable toilet bowl with a water storage tank and a narrow water storage surface, and a toilet bowl with a wide water storage surface and the water in the bowl that also serves as a water storage tank. In the former case, it is especially important to prevent filth from adhering to the toilet bowl, since the surface of the pooled water and the volume of the pooled water are concentrated around the point (position) where the filth is likely to be discharged. However, in the latter case, in addition to further improving water conservation, it also prevents splash dirt from adhering to the toilet (in the case of toilets with a wide water reservoir, the height of the water reservoir may be close to the distance from the toilet seat, so it is recommended to use the toilet while seated). The shape of the toilet bowl (installed with vertical grooves) and the installation of a foam film generating device are measures to prevent splash dirt from adhering to the back of the toilet seat, etc., in addition to the material of the toilet bowl (the coating on the toilet bowl itself). This has the effect that can be expected.

Toilet bowls with a wide water storage surface and the water in the bowl that also serves as a water storage tank have a thin foam film layer due to the water storage surface, which is difficult to maintain for a long time. As shown in Figure 1, the toilet bowl in this case has a narrow water storage surface (particularly an oval shape that is significantly narrower on the sides), resulting in a thick foam film layer, which is expected to maintain cleanliness for a long time. play.

Although it may partially overlap with what is stated in paragraph numbers 0015 to 0018, the accumulation of water containing an aqueous solution containing liquid detergent has the effect of suppressing the generation of germs and the like. In addition, since ventilation and dehumidification work is performed using a suction machine, it is also effective in suppressing the growth of mold and the like.

In addition to preventing splashes, the thick foam membrane layer also has the effect of suppressing odors such as filth and the sounds generated when using the toilet.

In this case, since a thick foam membrane layer is used, the foam membrane layer itself not only prevents dirt and droplets from adhering to it, but also serves as a lid to cover the entire wastewater on the surface of the reservoir. In this case, since the suction force of the suction device is the main source, the foam membrane layer itself can block the inflow of outside air from the drain port just before the suction of the sewage is finished. Therefore, it is possible to expect that contaminated water around the drainage port can be efficiently sucked.

Some existing products use a foam membrane manufactured using a different manufacturing method (manufactured by flowing water) to prevent splashing. However, when the foam membrane layer is thin and thin, the bubbles drain easily, but there is a lot of dirt from the splashes that stick to the product. When it's heavy, there's less dirt attached to it, but it's hard to remove bubbles. However, in this case, a thick foam film layer always covers the surface of the pooled water, preventing the adhesion of splashed dirt, and as stated in paragraph number 0021, a thick foam film layer is formed before the outside air flows in from the drain port. Since the foam film layer is suctioned, the foam is removed easily and the burden of rinsing work can be expected to be reduced.

Some existing products require consideration of the water pressure required for drainage work when installed in high-rise buildings, but in this case, the suction power of the suction machine is the main source, so low water pressure is required. It has the effect that it does not cause any trouble even if it is present.

After using the existing toilet, noise is generated for a long time due to the work of supplying water to the water tank and ventilation with a ventilation fan for deodorization, etc., but in this case, noise is generated for a long time due to the suction power of the suction machine. This has the effect that the noise generated during water supply work and ventilation work can be significantly shortened.

Hereinafter, FIGS. 1 to 5 are drawings showing configuration examples of a suction type toilet bowl according to the present invention.

FIG. 1 is a top view of the suction type toilet bowl according to the present invention. FIG. 1 is a BB sectional view of the suction type toilet bowl according to the present invention. FIG. 1 is a BB sectional view of the suction type toilet bowl according to the present invention. FIG. 1 is a BB sectional view of the suction type toilet bowl according to the present invention. FIG. 1 is a sectional view taken along line AA of the suction type toilet bowl according to the present invention.

The toilet bowl 1 is equipped with a suction device 8 and a suction port 13 around the S-shaped trap of the sewage drain pipe 14, and not only drains water using the flowing water power, but also uses the suction power of the suction device 8 to remove waste and other waste. Sewage 12 can be drained. In detail, as shown in Figures 2 to 4, in addition to installing a suction device 8 and a suction port 13 around the S-trap, there is also a toilet system that opens and closes the inside of the pipe at the bottom of the sewage drain pipe 14. A flapper valve 11 is installed. Next, by installing the suction device 8, the suction power can be used to quickly exhaust the odor after use to the outside, and the room can be ventilated and dehumidified regularly as well. In addition to this, it is also possible to shorten and suppress noise generated during water supply and ventilation. In detail, an outside air intake port 18 is installed around the toilet bowl 1, and multiple pipes (embedded in the stand below the toilet seat 3 of the toilet bowl 1) are installed to connect the outside air intake port 18 and the suction device 8. In addition, an air exhaust pipe 10 for discharging outside air and moisture from the suction device 8 to the sewage drain pipe 14 is separately installed. Next, there is a liquid detergent, a detergent tank 15 that stores the liquid detergent, a liquid feed pipe 16 that directly sends the liquid detergent from the detergent tank 15 to the water surface of the toilet bowl 1 or into the water supply pipe 19, and an aqueous solution containing the liquid detergent. A device 17 (hereinafter referred to as a foam film generator) that vibrates to generate a foam film layer is installed. Finally, this project is a measure to prevent the adhesion of filth and other dirt by changing the shape of the toilet bowl 1 to further reduce the water retention surface 6 and volume 7 of the toilet bowl 1, which are significantly smaller than existing products due to water conservation through suction power. It is necessary to perform a new process. The detailed countermeasure is to install vertical grooves 4 around the drain port 5 as shown in FIGS. 1, 2, and 5. The description that follows primarily concerns the configuration of conventional suction toilets.

The suction device 8 is operated for draining after using the toilet (transferring the sewage 12 in the standing water to the sewage temporary storage 9). However, since the bottom of the temporary sewage storage 9 is open as shown in FIG. In order to block the inflow of outside air, the toilet flapper valve 11 installed below the sewage drain pipe 14 is used to close the toilet. Thereafter, the suction device 8 is operated to suck the air inside the temporary wastewater storage 9 through the suction port 13, thereby lowering the air pressure inside the temporary wastewater storage 9 and sucking the wastewater 12. As for the suction device 8, it is preferable to install a suction device that uses a motor and fan used in vacuum cleaners with high suction capacity, a pump that uses a vacuum function, or a suction device used in dust collectors. . Regarding the installation location of the suction device 8, it is desirable to install it in the positions shown in FIGS. 2 to 4, but depending on the case, it is also possible to install it outside the toilet bowl 1 (outside the vicinity of the S-shaped trap). Moreover, the air discharged from the suction device 8 is discharged from the suction device 8 to the waste water drain pipe 14 through the air supply exhaust pipe 10.

Regarding the draining operation after using the toilet, the sewage 12 is transferred to the sewage temporary storage 9 by suction (see Figs. 2 and 3), so that the water level 6 decreases and the amount of stagnation 7 ( The dirty water 12) is almost in a state of being replaced. As the transfer time elapses, there is a possibility that the outside air from the drain port 5 will be sucked in preferentially over the residual sewage 12 around the drain port 5 due to the lowering of the water level 6. In order to preferentially suck out the residual sewage 12 around the drain port 5, it is necessary to separately shut off the outside air.As a countermeasure, the thick foam film layer generated by the foam film generator is regenerated before using the toilet. (for purposes other than preventing splashes and dirt adhesion) to block the outside air from the drain port 5 (by sandwiching the foam film layer left from the discharge work between the residual sewage 12 and the outside air, to separate the residual sewage 12 and the foam film layer. suction together).

The suction device 8 is used not only for transporting and suctioning the waste water 12, but also for deodorizing ventilation and dehumidification work using its suction power. They also serve as small fans and ventilation fans installed in some existing toilets. By installing it near the toilet bowl 1, which is the source of odor and moisture, it can be efficiently discharged to the outside. As shown in Figures 1, 2, and 5, the route is to install the outside air intake 18 around the toilet bowl 1, and connect the outside air intake 18 and the suction device 8 to the pipe (of the toilet bowl 1). A plurality of vacuum pumps (embedded in the stand below the toilet seat 3) are provided, and an air exhaust pipe 10 is installed to discharge air from the suction device 8, which is connected to a drain pipe 14 for sewage. This route not only performs deodorizing ventilation work but also dehumidification work on a regular or regular basis.

Since the drainage work in this case is mainly based on suction power, in addition to reducing the total amount of water used in the drainage work, the time required for water supply is reduced due to the positional advantage of ventilation work (ventilation fan installed around the ceiling). The time required for ventilation is significantly reduced, and the noise generated during each operation is also reduced. However, in order to utilize the ability of the suction device 8, it may not be possible to use it at the same time as emptying the toilet after using the toilet (in cases where the suction ability is significantly reduced). For this purpose, the tip of the suction device 8 (the connection portion with the suction port 13 and the outside air intake port 18) is configured to be switched to the suction port 13 or the outside air intake port 18 depending on the purpose of use.

Measures to prevent the adhesion of dirt from splashes, as well as the odor in the toilet bowl 1 after use and the noise made when using the toilet, can be prevented and suppressed by installing a foam membrane generator. Furthermore, since the water reservoir surface 6 becomes narrower, the foam membrane layer itself becomes thicker, and first, the long-term maintenance of the foam membrane layer and the above-mentioned ability are further improved. Regarding the vibrating device 17, there are methods such as installing a part of a small vibrator such as a small vibrator used in electric toothbrushes and mobile phones, a stirrer-type beer former, etc. directly into the water storage volume 7, and a method using the water storage volume of the toilet bowl 1. It is preferable to install a vibrating device 17 on the outer part of toilet bowl 7 (outside the bowl of toilet bowl 1) and generate a foam film layer through conduction vibration.

First of all, there are various theories as to why the toilet bowl 1, which has a wide water storage surface and the water in the bowl itself doubles as a water storage tank, was created, but the main reasons are to prevent dirt and other dirt from adhering to the toilet bowl 1, and to eliminate odors. We recognize this as a substitute for a water storage tank (emphasizing the mass and design of the toilet itself), which suppresses this problem only within the reservoir. Therefore, it was effective. However, on the other hand, the effectiveness could not be utilized on surfaces where there is a lot of dirt and droplets attached. Part of the reason why there is so much dirt from splashes is that the height of the pooled water surface is close to the distance from the toilet seat, so this issue is described in paragraph number 0031 as a countermeasure. However, in this case, not only the suction power but also the shape of the inside of the toilet bowl 1 is partially changed to further increase the water saving ability. There is a possibility of dirt adhesion. Therefore, as a preventive measure, vertical groove portions 4 are installed in locations where there is a high possibility of dirt adhesion, and locations where the possibility of contamination is low (especially both ends of the reservoir surface 6) are targeted for reduction of the reservoir surface 6 and reservoir water volume 7. The structure is as follows.

The following is a description of an embodiment of a normal suction type toilet bowl. Basically, the process is carried out as shown in FIGS. 2 to 4. In detail, in addition to installing a suction device 8 and a suction port 13 around the S-shaped trap of the wastewater drain pipe 14, a toilet flapper valve 11 is installed below the wastewater drain pipe 14 to open and close the inside of the pipe. It is installed. Next, by installing the suction device 8, the suction power can be used to quickly exhaust the odor after use to the outside, and the room can be ventilated and dehumidified regularly as well. In addition to this, it is also possible to shorten and suppress noise generated during water supply and ventilation. In detail, an outside air intake port 18 is installed around the toilet bowl 1, and multiple pipes (embedded in the stand below the toilet seat 3 of the toilet bowl 1) are installed to connect the outside air intake port 18 and the suction device 8. In addition, an air exhaust pipe 10 for discharging outside air and moisture from the suction device 8 to the sewage drain pipe 14 is separately installed. Next, there is a liquid detergent, a detergent tank 15 that stores the liquid detergent, a liquid feed pipe 16 that directly feeds the liquid detergent from the detergent tank 15 into the water reservoir surface 6 of the toilet bowl 1 or into the water supply pipe 19, and an aqueous solution containing the liquid detergent. A device 17 (hereinafter referred to as a foam film generating device) that generates a foam film layer by vibrating is installed. Finally, this project is a measure to prevent the adhesion of filth and other dirt by changing the shape of the toilet bowl 1 to further reduce the water retention surface 6 and volume 7 of the toilet bowl 1, which are significantly smaller than existing products due to water conservation through suction power. It is necessary to perform a new process. The detailed countermeasure consists of installing vertical grooves 4 around the drain port 5 as shown in FIGS. 1, 2, and 5.

When the user enters the toilet, the bubble film generator 17 operates for a certain period of time in conjunction with opening the toilet seat cover 2. On the reservoir surface 6, an aqueous solution containing liquid detergent that has been added after the previous use is collected, and there is a state in which an aqueous solution containing liquid detergent that has been added after the previous use is collected, and devices such as electric toothbrushes, small vibrators used in mobile phones, stirrer-type beer formers, etc. A vibrating device 17 may be installed on the outer part of the water reservoir volume 7 of the toilet bowl 1 (outside the bowl of the toilet bowl 1) to generate vibrations by conduction. A foam film layer is generated.

After a user uses (relieves) the toilet, drainage work is performed manually, using a motion sensor, a control panel, etc. First, the toilet flapper valve 11 is raised, and the bottom portion of the temporary wastewater storage 9 is closed. After that, the suction machine 8 is activated.

By operating the suction device 8 for a certain period of time, the air inside the temporary sewage storage 9 is sucked through the suction port 13 installed near the suction device 8, thereby lowering the air pressure inside the temporary sewage storage 9. Thereafter, the sewage 12 in the toilet bowl is sucked and moved to the sewage temporary storage 9. The outside air present in the temporary wastewater storage 9 during suction is discharged from the suction device 8 to the wastewater drain pipe 14 through the air exhaust pipe 10.

After that, as the water level 6 decreases, new outside air may flow in from the drain port 5. is blocked, and the residual sewage 12 around the drain 5 and the vertical groove portion 4 moves preferentially (the foam membrane layer itself serves to cover the drain 5).

After the sewage 12 is completely moved to the sewage temporary storage 9, the suction machine 8 is stopped, the toilet flapper valve 11 is lowered, and the bottom of the sewage temporary storage 9 is opened to perform drainage work.

Then, water is released from the water storage tank (or water supply device) (more than the volume of the stored water), and the entire inside of the bowl of the toilet bowl is cleaned by the water power. A part of the water is drained to a waste water drain pipe 14 (the bottom part of the temporary waste water storage 9 is open) while cleaning the waste water 12 as a rinse, and the remaining water is collected inside the bowl of the toilet bowl 1.

Thereafter, an appropriate amount of liquid detergent contained in the detergent tank 15 is poured into the water reservoir surface 6 through the liquid feed pipe 16.

When the next user enters the toilet, the same operation as in paragraph number 0034 is performed. After that, the following will be repeated.

Although this is separate from normal drainage work (cleaning work), the suction device 8 operates constantly or periodically again, and the outside air in the toilet room is sucked out from the outside air intake port 18 installed around the toilet bowl 1. Ventilation work is carried out by bringing in The outside air collected during the ventilation work is discharged from the suction device 8 to the sewage drain pipe 14 through the air exhaust pipe 10. This reduces the load on ventilation fans and reduces the noise generated during work. In addition, the generation of germs is suppressed, and dust can be removed regularly. However, in order to utilize the ability of the suction device 8, it may not be possible to use it at the same time as emptying the toilet after using the toilet (in cases where the suction ability is significantly reduced). For this purpose, the tip of the suction device 8 (the connection portion with the suction port 13 and the outside air intake port 18) is configured to be switched to the suction port 13 or the outside air intake port 18 depending on the purpose of use.

The operation is the same as in paragraph number 0042, but the suction device 8 operates constantly or periodically and uses suction power to draw in moisture from the toilet room through the outside air intake port 18 installed around the toilet bowl 1, thereby dehumidifying the toilet. I do. Moisture contained in the dehumidification work is also discharged from the suction device 8 to the waste water drain pipe 14 through the air exhaust pipe 10. This reduces the load on ventilation fans and reduces the noise generated during work. The growth of mold is also suppressed. However, in order to utilize the ability of the suction device 8, it may not be possible to use it at the same time as emptying the toilet after using the toilet (in cases where the suction ability is significantly reduced). For this purpose, the tip of the suction device 8 (the connection portion with the suction port 13 and the outside air intake port 18) is configured to be switched to the suction port 13 or the outside air intake port 18 depending on the purpose of use.

Possibilities for industrial use of the present invention include convenience as it has enhanced and evolved functions compared to conventional products. Further, by adding some of the functions of the present invention to a conventional product, the conventional product itself can be evolved or strengthened.
