Description

[Detailed description of the invention] This invention relates to an ice recycling device that purifies water used in washrooms, bathrooms, etc. with a simple device and reuses the water for flush toilets, etc. It is.

In recent years, with the concentration of population in cities, the amount of water used in cities has increased rapidly.

Flush toilets have become the norm not only in large cities but also in small and medium-sized cities, which is spurring an increase in water usage.

One of the major reasons for this is thought to be that drinking water is used directly for flush toilets and for watering.

Given that water resources are limited, leaving the situation as it is could endanger cultural life due to water shortages.

Large companies are partially recycling wastewater, but the equipment costs are too high and it cannot be used by ordinary households.

This invention was developed in view of the above points, and is intended to purify relatively uncontaminated water that has been used in washrooms, bathrooms, etc., and reuse it for flush toilets and watering. The purpose is to provide a simple device to realize the effective use of water resources in general households.

In order to achieve this purpose, the present invention is designed to connect used water drain pipes in washrooms, bathrooms, etc. to a branch pipe where one branch line is connected to the sewage system, and the other branch line of this branch pipe. A connected filter, a switching valve device provided in the branch pipe for switching between the sewage and the filter, a water tank for storing recycled water purified by the filter, and a water tank for using the recycled water in the water tank. It consists of a pump that sends out water to the

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows the device according to the present invention installed in a general household.

In this figure, 1 represents the floor, and on this floor 1,
Equipment that uses water, such as melting tank 2, washing machine 3, sink 4
, a wash basin 5, a flush toilet 6, etc. are installed.

Among the drain pipes 7 connected to these devices, the bathtub 2 and washing machine 3 are relatively uncontaminated even with used water.
, branch pipes 10 are connected to the discharge pipes 7 of the sink 4, respectively.

A switching valve device 11 as described later is attached to this branch pipe 10.

Further, one branch line 12 of these branch pipes 10 is directly connected to the sewer, and the other branch line 13 is connected to a filter 15 via a water intake port 14.

Further, the drain pipe 7 of the washbasin 5, which is particularly lightly contaminated, is directly connected to the filter 15, and conversely, the drain pipe 7 of the flush toilet 6, which is highly contaminated, is directly connected to the sewage.

The filter 15 is connected to a water storage tank 19 of the flush toilet 6 by a pipe 18 via a water storage tank 16, an electric pump 17, and a manual pump 42.

In addition, this filter 15 has a box-shaped container formed of a steel plate about 1 mm thick, and inside, in addition to a filter paper 20 and a gold steel 21, a disinfecting and deodorizing carbonic acid particle layer 22 is provided as necessary, and an upper part is covered with a handleable lid 23.

The water tank 16 connected to this filter 15 also has a diameter of 1 mm.
A box-shaped container is formed from thick steel plate, and a water storage amount meter 24 on the upper side of the floor 1 is connected to this water storage tank 16.
An overflow pipe 25 is connected, and this overflow pipe 25 is connected to sewage.

Next, the specific structure of the branch pipe 10 and the switching valve device 11 provided therein will be explained based on FIGS. 2 and 3.

The branch pipe 10 has two branch passages 12.
13 are connected together to form a downward Y-shape, for example, by gluing them together along a central vertical line 27.

Inside this rectangular tube 26, a valve body 28 for controlling the opening and closing of the branch passages 12.13 is provided so as to be swingable about an integral shaft 29.

This shaft 29 protrudes to the outside of the rectangular tube 26, and a horizontal rod 30 is integrally fixed to the protruding end thereof. 34.35, this plunger 34.35
is biased upward by internal springs 36, 37, and the electromagnet 3
2.33 is not operated, the valve body 28 is held at the neutral position.

In addition, parallel connecting rods 38 and 39 are provided at both ends of the horizontal rod 30.
It is connected to a convex manual lever 41 which is provided on the floor 1 and is rotatable about a shaft 40 via the lever.

A power button 42 is located near the bathtub 2, washing machine 3, and sink 4.
, a selection switch panel 4 having a reclaimed water side 43 and a drain button 44
5 is provided, and the recycled water side 43 and drain button 44 are connected to the electromagnets 32 and 33, respectively.

Next, the operation of the present invention will be explained.

The water storage amount meter 2 indicates whether the amount of water stored in the water storage tank 16 is sufficient.
4, and the button on the selection switch panel 45 is determined depending on the degree of contamination of the water to be drained.

When the water to be drained is relatively clean, the reclaimed water side 43 is pressed.

Then, one electromagnet 32 is energized and the plunger 34 is attracted against the spring 36, and the horizontal rod 30 is accordingly inclined, and the valve body 28 is rotated together with the shaft 29, so that the branch passage 12 on the sewage side of the branch pipe 10 is rotated. Close the branch passage 13 on the side of the filter 15.
open.

The used water is then led to a filter 15 via a drain pipe 7 and a branch pipe 10.

The used water sent to this filter 15 is filter paper 2
0, the water passes through the carbonate particle layer 22, solid matter is removed, disinfected and deodorized, and is stored in the water storage tank 16 as purified recycled water.

The reclaimed water stored in the water storage tank 16 is pumped to a water storage tank 19 of the flush toilet 6 by a pump 17.

In this case, the pump 17 operates when the water level drops to the water storage tank 19 of the flush toilet 6, and stops when the water level rises.
Next, when there is sufficient reclaimed water stored in the water tank 16, or when the level of contamination of the water to be drained is high, the drain button 44 of the selection switch panel 45 is pressed, which is preferably controlled by a flow switch.

Then, the other electromagnet 33 is energized and the valve body 28 rotates in the opposite direction to the above, opening the branch 12 to the sewage and closing the branch 13 to the filter 15.

Then, the used water is led to the sewer via a drain pipe 7 and a branch pipe 10.

In the case of a power outage, etc., the valve body 28 can be directly operated manually using a manual lever 41 as shown in FIG. It can be made to pump water.

In the embodiment described above, depending on the degree of contamination of the wastewater, the filter 15 can purify the wastewater to some extent using only the filter paper 20, so in such a case, the carbonic acid particle layer 22 may be omitted.

In the embodiment described above, the water storage amount meter 24 is used to know the water level of the water storage tank 16, but a buzzer or a lamp may be used to notify when the water level of the water storage tank 16 reaches a certain value or more.

Since the present invention is configured as described above, used water that has been used once for washing, cooking, etc. can be purified with a simple device, recycled water, and reused for flush toilets, watering, etc. .

Therefore, a large amount of potable water, which was conventionally used for flush toilets, watering, etc., can be saved.

Furthermore, since the device of the present invention is simple, it can be provided at low cost and can be expected to be installed and popularized in general households.
