Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to a double-structured dew-proof tank attached to a flush toilet or the like.

(Conventional dew-proof tank) FIG. 3 is a front sectional view showing a conventional dew-proof tank 2. As shown in FIG. The dew-proof tank 2 includes an internal tank 3 that stores flush water for the toilet bowl (not shown) in the flush toilet 1 and is housed within an exterior container 4. In other words, this dew-proof tank 2 prevents the air in contact with the outer peripheral surface of the entire tank, that is, the outer surface of the outer case 4, from being cooled by tank water storage, and prevents dew from adhering to the outer surface of the outer case 4. It's getting old.

By the way, in the illustrated dew-proof tank 2, in order to cope with use in a cold region or when the environmental temperature gets cold at night, the water stored in the internal tank 3 and the water sealed in the flush toilet bowl 1 are made to flow. , measures have been taken to prevent damage due to freezing. The essential part of this antifreeze measure is the flowing water supply valve 6 attached to the bottom of the internal tank 3.

FIG. 4 is an enlarged view of the bottoms of the internal tank 3 and the exterior container 4, showing the flowing water supply valve 6 in cross section. As shown in the figure, the flowing water supply valve 6 is configured such that the spindle 6a maintains the closed state of the internal tank 3 by the downward urging force of the spring 6b. The opening and movement of the flowing water supply valve 6 is controlled by an operating screw 7 screwed onto the bottom wall of the outer case 4.
It is now carried out by the upward spiral of
In addition, a valve seat 8a for a float valve 8 interposed between the bottom of the internal tank 3 and the bottom of the outer case 4 has a
A flowing water passage 8b is formed inside it. Therefore, when the operation screw 7 of the exterior device 4 is screwed forward, the flowing water supply valve 6 is opened by the rise of the spindle 6a, and water from the internal tank 3 is supplied to the valve seat 8.
The water is supplied to the flush toilet 1 via a.
For this reason, the trap water in the toilet bowl of the flush toilet bowl 1 is constantly flowing, and freezing is prevented. Also, the water level inside the internal tank 3 will drop due to the outflow of the flowing water, so water will continue to be supplied from the water tap 5 (see Figure 3) such as a ball tap, and the internal tank 3 will continue to be supplied with water.
Freezing is also prevented. Note that the amount of flowing water supplied varies slightly depending on the environmental temperature;
It is best to adjust the speed to around 60 per hour.

(Problems to be solved by the invention) As mentioned above, the anti-condensation tank 2 is designed so that the entire circumference of the internal tank 3 for storing cold water is covered with the outer case 4, so that the air surrounding the outer case 4 is cooled. I've made sure that it doesn't happen. However, as the flowing water flows on the inner bottom surface of the outer container 4, dew condensation occurs on the outer surface side, that is, the lower surface portion (indicated by continuous x marks). This kind of thing is caused by the dew-proof tank 2 of cold region specifications equipped with the flowing water supply valve 6 as described above.
This was a fatal drawback for toilets, and there was a danger that the tank or toilet bowl would be damaged due to freezing. Of course, dew condensation on the exterior container 4 induces dirt, mold, and the like.

The present invention was developed in view of the above-mentioned circumstances, and provides a new dew-proof tank (hereinafter referred to as the "invented tank") that completely suppresses the generation of dew and can be used safely in cold regions. The purpose is to

"Structure of the invention" (Means for solving problems) The gist of the tank of the present invention is that an internal tank for storing flushing water for the toilet bowl of a flush toilet is housed in an exterior container for preventing condensation. In a dew-proof tank in which a flowing water supply valve for preventing freezing is attached to the tank, the flowing water supply valve of the internal tank is provided with a water passage for guiding flowing water into the toilet bowl.

(Function) The flowing water from the internal tank is led from the flowing water supply valve to the flush toilet bowl via the water passer, and is designed not to come into contact with the inner surface of the outer container. Therefore, the outer packaging is not cooled,
There is no condensation on the outside surface.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a front cross-sectional view showing the main parts of the tank of the present invention, and is drawn in the same field of view as a conventional dew-proof tank (see FIG. 4) for easy comparison. The most distinctive feature of this tank is the flowing water supply valve 6.
The point is that a water passage device 9 is attached to the.

The water passage device 9 is integrally extended in the lateral direction of the valve seat 8a for the float valve 8, and is shaped like a saucer so as to surround a predetermined area below the flowing water supply valve 6. A feed hole 9b is bored in the inner surface of the water passage 9 and communicates with a flowing water passage 8b formed inside the valve seat 8a. FIG. 2 is a perspective view showing the water passage device 9 with a portion cut away. As shown in the figure, the water passage device 9
A mounting hole 9a for the operating screw 7 (see FIG. 1) is bored in the bottom wall of the holder. Note that the bottom wall of the water passage device 9 is formed one step higher than the bottom wall of the valve seat 8a. As shown in FIG. 1, this raised bottom measure forms an intervening space for the gasket 10 that prevents water from leaking around the mounting portion of the operating screw 7, and also prevents water flowing out from the flowing water supply valve 6. ,
It is also aimed at the effect of separating it from the bottom wall of the outer case 4 as much as possible.

In the tank constructed as described above, by screwing the operation screw 7 from the outside of the outer case 4, for example at night, the spindle 6a of the flowing water supply valve 6 is pushed up and opened, and the inner tank 3 The water inside is poured into the water passageway 9. The water is then supplied from the water passage 9 to the flush toilet bowl 1 via the flowing water passage 8b of the valve seat 8a. Note that when water flows through the flowing water passage 8b of the valve seat 8a,
It comes into contact with a part of the inner surface of the bottom wall of the exterior container 4, and the outer surface corresponding to this contact inner surface is connected to the annular embankment 1 for tank installation provided at the rear of the flush toilet 1.
1 (indicated by the two-dot chain line), so even if condensation occurs on this outer surface, the condensed water will be guided into the interior of the toilet bowl. Therefore, the air surrounding the outer case 4 is not cooled anywhere, and no dew is generated.

(Study of another aspect) The water passage device 9 does not need to be formed integrally with the valve seat 8a for the float valve 8. Further, since the mounting position of the flowing water supply valve 6 is not limited to the bottom surface of the internal tank 3, the setting position of the water passage device 9 can also be changed accordingly. Of course, the form of the tank targeted in the present invention is not limited to the illustrated stationary low tank, but may also be a suspended low tank, high tank, or the like. In this way, the configuration and shape of the tank of the present invention can be changed as appropriate depending on the embodiment.

"Effects of the Invention" As is clear from the above explanation, according to the dew-proof tank according to the present invention, dew condensation does not occur on the outer packaging. Therefore, no water freezes inside or outside the tank, and no damage to the tank or toilet bowl occurs. Of course, it has many excellent advantages, such as being able to prevent stains and mold caused by dew.
