Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a tank for storing water that is installed above a toilet for a flush-type toilet, and preferentially uses rainwater, remaining hot water of a bath, etc. as water to be stored in the tank, and saves tap water and rainwater. It is a device for the purpose of use.

[0002]

[Prior art]

 Conventionally, flush toilets utilizing rainwater are hardly available on the market. There are toilets that use rainwater found in publications that use rainwater and tap water by manually switching between them.

[0003]

[Problems to be solved by the invention]

 The amount of tap water used in flush toilets is not very large per use, but it is extremely large on a monthly or yearly basis. Water used in such toilets is not necessarily large. It is not necessary to use drinking water, so by giving priority to rainwater and automatically using both rainwater and tap water, even if rainwater disappears, there is no need to change the flush toilet. It is very convenient and effective to use rainwater if tap water can be used automatically.

[0004]

[Means for Solving the Problems]

 In view of the above-mentioned circumstances, the present invention relates to a flush toilet in which water filled in the tank flows out from a drain cock below the tank to a toilet placed below the tank by an operation such as twisting a lever. A ball tap provided above the tank and provided in a passage through which rainwater or the like flows into the ball tap, a ball tap poly ball fixed to the tip of a ball tap sao connected to the ball tap, and tap water located on the other side of the tank. It has a ball tap provided in the inflow passage and a ball tap poly ball fixed to the tip of the ball tap sao connected to the ball tap, and the tank is provided with a small hole at the bottom for rainwater etc. Space is installed, and rainwater etc. flows in preferentially when the water level in the tank drops due to operations such as twisting the lever The flush-type toilet tap is characterized in that the ball tap for rainwater etc. is positioned higher than the tap tap for tap water inflow so that the valve of the ball tap for inflow of rainwater etc. opens earlier than the valve of the ball tap for tap water inflow. .

【Example】

 An example of the case where rainwater is used effectively will be described below with reference to the drawings. By twisting the lever 1, the water filled in the tank 3 flows out of the drain plug 2 in the downward direction of the tank to a toilet (not shown) installed below the tank 3, and the water level in the tank 3 drops, and The rainwater inflow ball tap connected to the tip of the rainwater inflow ball tap connected to the rainwater inflow ball tap 5 installed at the upper part of the ball tap 6 is lowered, and the valve in the rainwater inflow ball tap 5 is lowered. Then, the rainwater in the rainwater reservoir (not shown) flows from the rainwater inflow pipe 4 through the rainwater inflow ball tap 5 and the rainwater inflow hose 8 into the rainwater inflow exclusive box 14 which is a dedicated space for rainwater inflow. At the same time, the rainwater also moves into the tank 3 from the small hole 15 at the lower part of the rainwater inflow exclusive box. At this time, since the size of the small hole 15 is smaller than the inner diameter of the rainwater inflow passage 8, the rainwater flows from the rainwater inflow hose 8. The amount of water flowing into the rainwater inflow box 14 does not decrease, but instead the rainwater accumulates in the tank 3 while overflowing from the upper part of the rainwater inflow box 14. Is also very small. Therefore, the tap water inflow ball tap connected to the tap water inflow ball tap 10 connected to the tap water inflow ball tap 10 and the tap water inflow ball tap attached to the tip of the sao 11 do not move downward. Absent. Therefore, when rainwater flows in until the rainwater inflow ball tap poly ball 7 rises, the valve in the rainwater inflow ball tap 5 closes and the inflow of rainwater stops.

[0006] When there is no rainwater in the rainwater reservoir (not shown), the water level in the tank 3 first drops, and at the same time, the tip of the ball tap sao 6 connected to the rainwater inflow ball tap 5 installed above the tank, as described above. The ball tap cup ball 7 attached to the ball falls. However, since rainwater does not flow into the rainwater inflow box 14, water moves into the tank from the small hole 15 at the lower part of the rainwater inflow box, and the water level in the rainwater inflow box 14 decreases, so that the tap water inflow does not flow. Ball tap spring 11 connected to ball tap 10 Ball tap poly ball 13 attached to the tip moves downward, and the valve in tap tap 10 for tap water inflow opens, and tap water flows from hose 9 to tap water. Tap water starts to flow into the tank 3 from the tap water inflow hose 12 through the ball tap 10 for water inflow. At this time, although a little water flows into the rainwater inflow box 14 from the small hole 15 below, rainwater does not flow from above, so the ball tap poly ball 13 for tap water does not move upward. Tap water will continue to flow into tank 3. Then, the tap water which continues to flow into the tank 3 flows from the lower hole in the rainwater inflow box 14 or the upper part of the rainwater inflow box 14, and the tank 3 is filled with the tap water. The ball tap poly ball 13 attached to the tip of the ball tap spring 11 connected to the tap tap 10 for tap water inflow rises and the supply of tap water stops.

If the rainwater in the container for storing the rainwater in the first period is small, the rainwater may be interrupted while flowing into the tap water inflow box 14, but in this case, the rainwater inflow from the small hole 15 in the lower part of the rainwater inflow box is reduced. Since the water is continuously moving into the tank 3, the water level in the rainwater inflow box 14 drops when the rainwater runs out, and the ball tap sao 11 connected to the tap water inflow ball tap 10 The ball tapping poly ball 13 attached to the tip of the tank moves downward and the tap water starts to be supplied into the tank 3. After that, it will be the same as when using tap water in the previous term. In this way, rainwater can be used preferentially, tap water can be automatically used even if the rainwater in the reservoir for rainwater runs out, and tap water need not be wasted. If domestic wastewater is effectively used instead of rainwater, toilets can be used even if water is cut off without rain for a long time.

When the rainwater inflow box 14 is not fixed to the tank 3 and the tap water continues to flow into the tank in the previous term, the rainwater does not flow into the rainwater inflow box 14 because the rainwater does not flow into the tank. The box floats or moves in the horizontal direction. Therefore, if the inflow position of the tap water is adjusted so as to partially flow into the rainwater inflow box 14, the rainwater inflow box does not move. For example, a hole may be made slightly before the end of the tap water inflow hose 12 so that the water flows into the tank 3 from the end and flows into the rainwater inflow box 14 from the hole. If the inflow conditions in the previous period are satisfied, the inflow position of the rainwater into the rainwater inflow box and the tap water inflow into the tank may be set at any position. If it is fixed in the tank, the rainwater inflow box will not move or float, but it is troublesome to install a rainwater inflow box in a commercially available flush toilet tank. The invention can be implemented

It is preferable that the rainwater inflow box be as small as possible. The reason is that when rainwater flows in, the water in the rainwater inflow box is constantly full and the part does not flow to the toilet, so the entire tank is not used. Also, if the rainwater inflow box is small, the response when the ball tap poly ball goes up and down depending on the water level will also be better. In this case, the ideal size should be the cross-sectional area seen from the upper part of the ball tap poly ball, so that the size leaving a margin for the ball tap poly ball to move up and down is good. If the rainwater inflow box is small, a table may be placed under the box, but it is important to minimize the volume of the table as much as possible to increase the volume in the tank. For this reason, the shape of only the skeleton is preferable as in the case of the table 15 shown in FIG.

The box for rainwater inflow may have another form. For example, it may be divided by making a partition plate. The box can have any shape, material, etc. as long as it does not move or float when rainwater or tap water flows in. However, a material with a specific gravity as large as possible and a material that does not easily rust is preferable to make it difficult to move or float. For example, stainless steel, duralumin, ceramics, pottery, plastics, etc. can be used. In the case of plastics, it is better to use a plastic material having a density of at least one such as polyethylene, polypropylene, polybutylene terephthalate and the like. In such a case, adding a filler such as silica sand or tungsten will increase the density further, which is convenient. It is also possible to put stones, bricks, etc. at the bottom of the rainwater inflow box and weigh it. The rainwater inflow box can be provided with a partition plate in the flush toilet tank, or the box united with the main unit can be made during the manufacturing process.

It is desirable that the diameter of the small hole 15 below the rainwater inflow box 14 be smaller than the inner diameter of the rainwater inflow hose 8. The basis for determining these diameters is based on the amount of water flowing from the rainwater inflow hose 8 ( It suffices that the flow rate (flow rate) is larger than the water quantity (flow rate) moving into the tank 3 from the small hole 15 below the rainwater inflow exclusive box 14. Therefore, it is not necessarily determined by the inner diameter, but the actual capacity of the tank 3, the capacity and height of the rainwater inflow box 14, and the amount of outflow to the toilet (not shown) below the tank 3 (the size of the discharge plug 2). ) Etc. However, if the diameter of the small hole 15 below the rainwater inflow exclusive box 14 is too large, the water in the rainwater inflow exclusive box 14 may be discharged when water flows out to the toilet bowl (not shown) at the bottom of the tank 3. At an early stage, the tap water tapping ball tap 10 connected to the tap water inflow ball tap 10 moves into the tank, and the tap water inflow ball tap poly ball 13 attached to the tip of the tap water sink 11 moves downward. This is inconvenient because tap water starts to be supplied into the tank 3 and must be set to an appropriate size. If the diameter of the small hole 15 below the rainwater inflow box 14 is reduced, the water in the rainwater inflow box 14 will slowly drain when the water flows out to the toilet bowl (not shown) at the bottom of the tank 3. 3, the tap water inflow ball tap attached to the tip of the tap water inflow ball tap 10 connected to the tap water inflow ball tap 10 that moves into the tap water 3, and the downward movement of the poly ball 13 is slowed down. The opening of the valve of the inflow ball tap 10 is delayed, which saves tap water.

Ideally, the small hole 15 below the rainwater inflow exclusive box 14 is provided up to the water surface position of the lowermost effective operating range of the tap water inflow ball tap poly ball 13 to which tap water is supplied. Since there is always water in the special box up to the position of the small hole, the special box is difficult to move or float even if the weight of the special box itself is light.

[0013] Although an example of utilizing rainwater has been described above, the present invention is not limited to rainwater, but may be anything such as remaining hot water in a bath, well water, and relatively dirty sewage. However, water containing insoluble impurities must be filtered to some extent before use.

[Effect of the invention]

 If the present invention is used, rainwater can be used preferentially in flush toilets, and even if the rainwater in the container for storing rainwater runs out, tap water can be used automatically, so that useless tap water is not required. Therefore, it is economical and if toilet water is used effectively instead of rainwater, it can be used even if water is cut off without rain.
