Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-washing pot such as a low tank integrated with a flush toilet body or a corner-mounted low tank installed at a corner of a toilet room. The present invention relates to a configuration that makes it easy to handle.

[0002]

2. Description of the Related Art A low tank equipped in a flush toilet has a general structure in which a ball tap connected to a water supply pipe on the building side is built in and a hand-washing pot is provided at an upper end. Then, the ball tap is connected to the flow path to the water discharge pipe provided in the hand-washing pot, and a water supply unit that directly opens into the low tank is provided, and part of the water supply from the water supply pipe is collected in the low tank via the hand-washing pot To be done.

Such a construction is also applicable to a corner type low tank which is provided separately from the toilet bowl and is installed at the corner of the toilet room. Further, it is also used in the case where the flush water tank and other functional parts provided in the toilet body are covered with a casing and the upper end of this casing is used as a hand-washing pot.

[0004]

The water supplied from the ball tap and the water collected from the hand washing bowl are finally discharged to the toilet side and used as washing water. By using such a flow of water supply, chemicals whose main purpose is deodorization, aroma and cleaning are put in a low tank or placed in a hand washing bowl to have an effect on the cleaning water discharged to the toilet side. It is widely used in ordinary households.

[0005] The drug is to drop the soluble solid matter into the washing water in the raw tank as it is exposed, or put it in a special container and place it on the handwash pot to expose the drug to the water supply from the spout pipe. Dissolve in the wash water accumulated in the low tank, and then discharged to the toilet side.

However, when a chemical is put into the low tank, the lid of the tank is opened each time,
It takes time and effort. Further, in the case where the casing is integrally provided with the hand washing bowl, such a medicine cannot be put into the tank.

On the other hand, in the method of placing the drug on the hand-washing pot, the drug is put in the container, and the lower end of the container is inserted into, for example, a drain port provided at the bottom of the hand-washing pot and opened toward the tank. It is as easy to use. One reason for using the container in this way is to prevent the water from coming out of the water discharge pipe from hitting the medicine and bouncing back directly from the water, which causes the solid component to elute and become colored water, which then adheres to clothes and the like. .

As described above, in the conventional low tank, it is general to use the solid medicine as a container in a hand-washing pot. For this reason, colored water may adhere to the ball surface of the hand-washing pot, and the container itself may become soiled with elution components, impairing the original hygienic atmosphere of the hand-washing pot for washing hands. Become.

The problems to be solved in the present invention are deodorization,
The purpose is to put a solid chemical agent having an effect of aroma and cleaning into the bowl of a hand-washing pot as it is or put it in a cleaning water tank so that it can be optimally used.

[0010]

SUMMARY OF THE INVENTION The present invention is provided with a flush water tank for storing flush water for flushing a toilet bowl, and has a spout for discharging the water supplied from a water supply source. It is a hand-washing pot for returning discharged water to the wash water tank, and at least one or more effects of aroma, disinfection, deodorization and cleaning are provided in the middle of a flow path in which the water discharged from the spout flows into the wash water tank. It is characterized by comprising a holding portion capable of holding the medicine held therein by exposing it to a water stream.

In the holding portion, the outer periphery of the discharge port, which projects downward from the bottom surface of the bowl of the hand washing bowl and faces the wash water tank, may have a concave vertical sectional shape capable of receiving the medicine.

Further, at the bottom of the ball, facing the washing water tank, there is provided an outlet through which a drug having at least one of the effects of aroma, disinfection, deodorization and cleaning can pass, and the drug can be received. It is also possible to have a structure in which a perforated plate having a concave vertical cross-sectional shape is detachably attached to the discharge port.

Further, the discharge port may be provided apart from the portion where the water supply falls from the water discharge port, and a water guide channel for guiding the water supply from the portion where the water supply falls to the discharge port may be provided.

[0014]

[Function] A holding part is provided in the place where the water flows from the handwash pot to the wash water tank, and by placing a drug in this holding part, the component can be eluted while being exposed to water, and Water can be flushed back into the wash water tank with the drug elution.

By making the holding portion a recess having a size capable of receiving the medicine therein, the holding portion can be set to be embedded in the bottom surface of the ball, and the medicine can be sufficiently immersed in the water from the spout. It will be possible.

Further, by providing the ball with an outlet having a size through which the medicine can pass, the medicine can be directly used in the washing water tank for use. Further, if a perforated dish having a concave vertical cross-sectional shape capable of receiving a drug is detachably attached to the inside of the upper end side of the discharge port, it can be used even when the drug is placed on the perforated plate.

Furthermore, by separating the water supply dropping portion from the discharge port and the water discharge port, the drug set in the discharge port does not directly hit the drug, and the excess drug is not eluted. In addition, by providing a water conduit between the water supply falling part and the outlet, the water supply can be sufficiently sent around the chemical solution,
Even if the amount of water supplied from the water outlet is small, there is no shortage of elution of the drug.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the outline of a toilet device equipped with a hand washing bowl according to the present invention. It should be noted that, in the embodiment, the hand-washing pot provided at the upper end of the casing containing the wash water tank described in the section of the prior art will be described.

In the figure, a casing 2 is fixed to the upper surface of the toilet body 1, and a toilet seat 3a and a toilet lid 3b are attached to the casing 2 so as to be openable and closable. The casing 2 incorporates therein a nozzle device for local cleaning, a hot water supply piping system, and a warm air dryer for drying after cleaning, and a cleaning water tank 2a for cleaning the ball portion.
And the like, and the upper end portion is a hand-washing pot 4 with a water discharge pipe 5.

The wash water tank 2a is connected to the water supply pipe on the building side similarly to the conventional structure, and a part of the water supply can be supplied also to the water discharge pipe 5 side by a built-in ball tap.

FIG. 2 is a perspective view showing the outline of the hand-washing pot 4, and FIG. 3 is an enlarged vertical sectional view taken along the line AA of FIG.

The hand-washing pot 4 is one in which the water discharge pipe 5 is fixed to a rising wall at the back so that the water discharged from the water discharge pipe 5 falls almost in the center of the ball 4a, and the pipe is incorporated inside the rising wall. Thus, the water discharge pipe 5 is connected to the ball tap in the wash water tank 2a.

On the bottom surface of the ball 4a, a water conduit 4b is formed which is recessed from the position where the water is discharged toward the left side. The end of this water conduit 4b is surrounded by the rim 4c. An M holding portion 4d is provided. This holding portion 4d is shown in FIG.
As shown in (4), the depth is drastically deepened from the end of the water conduit 4b into a substantially mortar-like shape, and the inner diameter of the upper end edge is about 80 mm, which is a volume capable of dropping the medicine M currently generally used as it is. Then, when the drug M is placed,
A plurality of ridges 4d-1 which corrugate the inner peripheral wall of the holding portion 4d in the circumferential direction are provided so that a gap is formed between the peripheral edge of the lower end and the inner circumference of the holding portion 4d.

A discharge port 4e having a small inner diameter is projected from the lower end of the holding portion 4d, and the discharge port 4e is inserted into the casing 2
The water received by the balls 4a is inserted into the opening 2c opened in the lid 2b of the washing water tank 2a therein so that the water is poured into the washing water tank 2a. Further, a sub-meal plate 4f is detachably incorporated in the upper end portion of the discharge port 4e for preventing foreign matter from flowing into the wash water tank 2a.

In the above structure, if the solid medicine M is left as it is in the holder 4d as shown in FIG. 3, the water from the water discharge pipe 5 passes through the water conduit 4b into the holder 4d. As it flows in, the drug M is exposed to water and its components elute,
It is collected in the wash water tank 2a. Therefore, in the interior of the wash water tank 2a, in addition to the amount of water directly supplied from the ball tap, water containing the elution component of the drug M is mixed, and the wash water containing the drug M enters the bowl portion of the toilet body 1. Supplied.

Since the holding portion 4d is located away from the water discharge pipe 5, the water from the water discharge pipe 5 does not directly come into contact with the water and is exposed to the flow of water flowing down from the water conduit 4b. Only. Therefore, for example, the water discharge pipe 5 is added to the medicine M.
In the case where the water from the product comes into direct contact, the drug M
Since the surface of the is eroded and more components than necessary are easily eluted, by exposing it to the flow of water,
There is no such excess component elution.

Further, since the medicine M is lower than the bottom surface of the ball 4a, it does not interfere with the washing of hands, and there is no splash of water from the medicine M. You won't even get your hands on it.

FIG. 4 is a schematic view showing an example in which the medicine M can be dropped into the wash water tank 2a, and FIG. 5 is a view B in FIG.
FIG. 7 is a vertical cross-sectional view of the main part at the position of arrow B.

A cylindrical drain port 4g having a length that penetrates an opening 2c formed in a lid 2b of the wash water tank 2a is provided substantially at the center of the ball 4a. The drain port 4g has an opening cross section that is large enough to drop the medicine M into the cleaning water tank 2a.

Thus, the ball 4a has a large-diameter drain port 4g.
By providing the handwash bowl 4 itself with the casing 2
The chemical M can be put into the wash water tank 2a without removing it from the container or opening the lid 2b. Therefore, compared with the case where the medicine M is stored in the container and placed on the ball 4a, the appearance is improved and at the same time, the damage due to splashing of the colored water is eliminated.

Here, the medicine M cannot be directly introduced unless the inner diameter of the drain port 4g is set to about 80 mm as in the case of the holding portion 4d in the previous example. However, if the drain port 4g having a large inner diameter is opened in the ball 4a as described above, there is a possibility that an object may be dropped while washing the hands.

On the other hand, such an inconvenience is eliminated by incorporating the detachable eye plate 6 into the drain port 4g. The eye plate 6 is the holding portion 4d shown in the previous example.
It has a cross-sectional shape almost similar to that of the above, and is formed in a mortar-like shape, and a discharge plate 6b at the lower end is detachably provided with a small plate 6b.

When such a perforated plate 6 is provided, it is removed and the chemical M is put into the washing water tank 2a from the drain port 4g for use. In addition, the perforated plate 6 is drained as shown in FIG. It is also possible to place the medicine M in the eye plate 6 and use it as in the previous example.

In preparation for use in the latter case, if the inner diameter of the eye plate 6 is set to about 80 mm, the drug M can be dropped into the eye plate 6 as in the previous example, and the drug M is projected upward from the ball 4a. No set is possible. Then, in order not to receive the water from the water discharge pipe 5 directly, by shifting the water discharge pipe 5 and the drain port 4g back and forth or left and right, the medicine M can be exposed in the flow of water, Elution of excess components is also prevented. Further, the inner diameter of the drainage port 4g is also increased correspondingly to the increase in the inner diameter of the eye plate 6,
When the chemical M is thrown into the wash water tank 2a and used, the chemical M easily passes through the drain port 4g, which is rather convenient.

As described above, the large-diameter drain port 4g is provided, and the dish 6 is detachably attached to the drain port 4g so that the medicine M is contained in the balls 4a or thrown into the wash water tank 2a. Can be used properly. Therefore, for example, first, the medicine M is set on the ball 4a side using the eye plate 6, and the medicine M gradually elutes and becomes smaller, and the flow of water from the water discharge pipe 5 is sufficient. When the elution is no longer possible, the user can remove the eye plate 6 and throw it from the drainage port 4g into the wash water tank 2a to secure the elution amount, which is convenient.

Although the hand-washing pot provided in the casing has been described in the embodiment, the same applies to a hand-washing pot such as a flush water tank directly mounted on the toilet body or a wall-fixing corner-attaching low tank.

[0037]

According to the present invention, a solid chemical having effects such as deodorant, aroma and cleaning is placed in a holding part provided in the flow path from the hand washing pot to the cleaning water tank, or the cleaning water tank It can be thrown in and used, and the drug can be optimally used according to the conditions of use and the size of the drug.

When the medicine is placed on the holding portion, the medicine is buried in the bottom surface of the ball so that it does not interfere with hand washing and prevents the hands and clothes from being splashed due to splashing of water. It

Further, by preventing the water supplied from the water outlet from directly hitting the medicine, it is possible to eliminate the excessive elution of the medicine, and by providing a water guiding path between the concave holding portion and the holding portion. A sufficient water flow can be created around the medicine, and the elution amount can be secured even if the amount of water supplied from the water outlet is small.
