Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet cleaning tank provided with a cleaning tank for storing toilet cleaning water, and more particularly to handwash water introduction for reducing the noise of water supply into the toilet cleaning tank. The present invention relates to a toilet bowl cleaning tank equipped with members.

[0002]

2. Description of the Related Art It has been known that a toilet bowl cleaning tank is provided with a hand-washing spout and a hand-washing pot at the top of the cleaning tank. This type is very popular because it does not require a separate hand-washing facility and saves space. And, in the toilet bowl cleaning tank equipped with such a hand washing bowl, some measures have been taken to muffle the water supply noise. In particular, in order to prevent dripping noise that occurs when hand washing water falls from the hand washing water outlet of the hand washing bowl to the surface of the washing water stored in the washing tank, wires, chains, etc. to prevent the hand washing water from being transmitted. Or as disclosed in Japanese Patent No. 3159051, a hand washing water conducting member for dropping the hand washing water along the inner wall of the washing tank is provided.

[0003]

However, in addition to the cleaning tank, the toilet cleaning tank has many components such as a ball tap, an overflow pipe, a discharge valve, a floating ball, a cleaning handle spindle, and the like as described above. If you use wires, chains, etc., they may interfere with other parts and cause malfunctions.In cold regions, the water accumulated on the wires, chains, etc. will freeze, reducing the noise reduction effect. There was something that happened. Further, in the hand-washing water conducting member as described in Japanese Patent No. 3159051, the force of the water flowing through the hand-washing water conducting member is too strong because the water supply pressure at the place where the toilet cleaning tank is installed is high. Then, the hand-washing water may get over the inner wall of the wash tank, and part of the hand-washing water may not be properly stored in the wash tank or may jump out of the wash tank.

The present invention has been made in view of the above-mentioned conventional circumstances, does not cause a malfunction, does not deteriorate the sound deadening effect even in cold regions, and can reliably introduce hand-washing water into the washing tank. It is an issue to be solved to provide a toilet bowl cleaning tank.

[0005]

In order to achieve the above-mentioned object, a toilet bowl cleaning tank according to a first aspect of the present invention is provided with a cleaning tank for storing toilet cleaning water and an upper portion of the cleaning tank. , A hand washing pot having a hand washing water outlet for discharging the hand washing water from the hand washing water outlet to the inside of the washing tank, and a hand washing water conducting member provided so as to be located below the hand washing water outlet and above the washing tank. In a toilet bowl cleaning tank equipped with the above, a concavo-convex portion is provided on the water channel surface of the hand-washing water conducting member.

According to the second aspect of the invention, the toilet bowl cleaning tank is provided with a plurality of irregularities on the water channel surface of the hand-washing water conducting member.

In the toilet cleaning tank according to the third aspect of the present invention, the concavo-convex portion of the water channel surface of the hand-washing water conducting member is formed in a V shape along the water flow direction.

[0008]

In the toilet cleaning tank according to the first aspect of the present invention, since the hand-washing water conducting member does not interfere with other parts, no malfunction occurs. Further, since the hand-washing water conducting member does not store the hand-washing water, the sound deadening effect is not deteriorated even in cold regions.
Further, since the water surface of the hand-washing water conducting member is provided with the irregularities, even if the momentum of the hand-washing water is strong, the momentum is weakened by the irregularities and is suitably guided into the washing tank.

In the toilet bowl cleaning tank of the second aspect, since the plurality of concave and convex portions are provided, the action and effect of the first aspect is large.

In the toilet bowl cleaning tank of the third aspect, since the uneven portion is formed in a V shape along the water flow direction, the momentum of the hand washing water can be reliably alleviated.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows the appearance of the toilet bowl cleaning tank of the present invention in use. A toilet cleaning tank is installed in the upper rear part of the toilet bowl 2. The toilet bowl cleaning tank is provided with a hand-washing pot 3 having a hand-washing spout 4 at the top of the tank cover 1.

FIG. 2 is a vertical cross section of the toilet bowl cleaning tank. At the lower part of the hand-washing pot 3, a hand-washing water discharge port 5 for discharging the hand-washing water discharged from the hand-washing spout 4 into the washing tank 10 is formed. In the toilet bowl cleaning tank, a cleaning tank 10 is installed inside a tank cover 1, and a tank lid member (hand wash water guiding member) 6 is attached to the upper portion of the cleaning tank 10.

FIG. 3 is a plan view of the tank lid member 6. At the center of the tank lid member 6, there is formed a water channel surface 7 for guiding the hand washing water discharged from the hand washing water discharge port 5 of the hand washing bowl 3 to the inner side surface of the washing tank 10, and the water channel surface 7 A plurality of V-shaped concavo-convex portions 8 are formed on the top so as to be arranged in the vertical direction.

FIG. 4 is a front view of the tank lid member 6, and FIG. 5 is a sectional view of the tank lid member 6 as viewed from the right side. On the front surface of the tank lid member 6, an outlet 9 is formed for letting out the hand washing water that has flowed into the tank lid member 6 to the inner surface of the washing tank 10.

The flow of hand-washing water will be described below. The hand-washing water discharged from the hand-washing spout 4 drops from the hand-washing outlet 5 of the hand-washing pot 3 to the tank lid member 6, passes through the water channel surface 7 and flows out from the outlet 9 to the inner surface of the washing tank 10. When the hand washing water passes through the waterway surface 7, due to the interference of the V-shaped uneven portion 8 formed on the waterway surface 7,
Water force weakens. As a result, all the hand washing water can flow out from the outflow port 9 without overflowing from the tank lid member 6.

Further, the type of the tank cover 1 or the washing tank is changed by forming not only one V-shaped concave portion or convex portion but a plurality of concave and convex portions 8 in the water flow direction. Even if the position of the hand-washing water outlet 5 is slightly changed, the hand-washing water from the hand-washing water outlet 5 can be favorably received.

In this embodiment, the uneven portion 8 formed on the waterway surface 7 has a plurality of V-shapes.
It may be in the shape of a letter or other irregular shape.

[0018]

As described in detail above, the present invention has the following effects. In the toilet bowl cleaning tank of the present invention, since the hand-washing water conducting member does not interfere with other parts, malfunction does not occur. Further, since the hand-washing water conducting member does not store the hand-washing water, the sound deadening effect is not deteriorated even in cold regions. Furthermore, when the hand-washing water passes through the hand-washing water conducting member, the water pressure is weakened by the irregularities, so that the hand-washing water can be introduced into the toilet bowl without overflowing from the hand-washing water conducting member. Therefore, according to the toilet bowl cleaning tank of the present invention, malfunction does not occur, the sound deadening effect does not deteriorate even in cold regions, and hand washing water can be reliably introduced into the cleaning tank.
