Abstract

PROBLEM TO BE SOLVED: To provide a feed water device which is of an extremely thin type and does not require a large installation space and from which water can be easily taken out from a thin water storage part thereof in case of emergency. SOLUTION: Under such conditions that by using tap water, water flows continuously and there is not dead water, water is always ensured in a water storage channel comprising tubular members. In case of emergency, by opening a lower faucet 4 for feeding water, an air valve, which is normally closed by water pressure, is opened, and hence water stored in large quantities in the tubular members can be used by allowing the water to naturally flow down. Particularly, since the feed water device 6 comprises a framed body prepared by collecting separate thin tubular members, the device has a high strength and can be efficiently assembled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency water supply system capable of supplying water even in the event of a disaster or a shortage of water.

[0002]

2. Description of the Related Art Conventionally, as means for securing domestic or drinking water in the event of a disaster or drought, tap water has been stored in a household plastic tank, or drinking water in a plastic bottle has been purchased. .

[0003]

However, the above-mentioned means for storing tap water in the household plastic tank is troublesome to work on, and has a considerable space in the storage space. As described above, even if the drinking water in a PET bottle is purchased and stored, the water quality of the storage changes over a long period of time, so that the water must be replaced one after another.

Therefore, an emergency tank installed in the middle of tap water and in which water in the tank is circulated by constantly used water is disclosed in Japanese Utility Model Publication No. 53-40673. However, this system has a large tank capacity and must be buried underground, so the installation work is difficult. Also, in order to pump water in an emergency, an air pump or the like must be used, which not only has a high failure rate,
I had to think about securing a power source.

Further, Japanese Utility Model Publication No. 51-39212 discloses a circulation type tank installed on the side of a faucet, but it still takes up space as an installation place.

Further, a problem common to these prior arts is that when tap water is used, tap water constantly flows into the tank, causing water to flow, but due to the large diameter of the tank, dead water regions are likely to occur and There was a problem with the quality of the water supplied in an emergency because the water that could not be supplied remained in the tank.

The present invention has been made in order to solve the above-mentioned problems, and is an extremely thin and space-saving emergency water supply device which can easily take out water from these thin water reservoirs in an emergency. It is intended to be provided.

[0008]

The emergency water supply system of the present invention comprises a plurality of tubular members having an inlet at one end and a drainage port at the other end arranged laterally in the vertical direction. A frame is formed by liquid-tightly connecting and holding both ends to a pair of side plates, and forming a communicating portion that sequentially connects the drain port of a single tubular member and the inlet of another tubular member to each of the side plates, The inlet of the uppermost tubular member is provided on the upper side of one side plate to communicate with the water supply pipe, and the drainage port of the lowermost tubular member is provided on the lower end of the other side plate to communicate with the water outlet, and these are configured. It is characterized by installing an air valve at the top of the flowing waterway. Due to this feature, tap water is used to sequentially flow water, and water is always secured in the running water channel formed by these tubular members without dead water. In an emergency, the air valve that is constantly closed by water pressure is opened by opening the lower water supply cullan, so that the water stored in these tubular members can be used in large quantities by natural fall. In particular, since this water supply device is composed of a frame body in which independent tubular members are assembled, the water supply device has high strength and the piping assembling work is made efficient.

In the emergency water supply system of the present invention, the end portions of the respective tubular members facing each other of the communicating portion that communicates the inlet of the single tubular member and the drain outlet of the other tubular member are the communicating portions. It is preferable that they are communicated with each other through a communication part of a passage that is larger than the water flow resistance. With this feature, the water in the plurality of tubular members does not pass through the communication part of the passage having high resistance,
Since the communication part with less resistance is positively flowed down, the flow is not short-circuited. Therefore, during normal use of water, sufficient water flow can be obtained, and high-quality water can always be secured.

In the emergency water supply system of the present invention, it is preferable that the communication part having a large flow resistance is a slit-shaped communication part formed in each of the side plates. Due to this feature, even if fine particles such as red rust are partially clogged in the slit-shaped drainage hole of a predetermined length, the clogging is partial and the communication portion is less likely to be blocked.

The emergency water supply system of the present invention is characterized in that the plurality of tubular members are a frame body that is inclined together with the pair of side plates in one direction. Due to this feature, the water flows smoothly in an emergency, and when the water flows into the emergency water supply device again, the air easily collects on one side and the air is efficiently discharged.

In the emergency water supply device of the present invention, a plurality of tubular members having an inlet port at one end and a drain port at the other end are laterally arranged vertically, and the inlet port of the single tubular member is While forming a flow-type flowing water channel that is integrated by sequentially connecting the drain ports of other tubular members with a connecting portion, at least an air valve is installed near the top of the plurality of integrated tubular members, The inlet of the uppermost tubular member is connected to the water supply pipe, the drainage port of the lowermost tubular member is communicated with the water outlet, and the inlet of a single tubular member and the drainage port of another tubular member In an emergency water supply device in which the end portions of the respective tubular members facing the communication portion are connected by a communication portion having a larger flow resistance than the communication portion, the communication portion having a large flow resistance is formed in a slit shape. I am trying. Due to this feature, even if fine particles such as red rust are partially clogged in the slit-shaped drainage hole of a predetermined length, the clogging is partial and the communication portion is less likely to be blocked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments and the drawings. FIG. 1 is an overall view of an emergency water supply system showing an embodiment of the present invention. The kitchen 1 shown in FIG. 1 is mainly composed of a sink 2, a sink portion 3 provided on the sink 2, a water supply currant 4 provided above the sink portion 3, and the like. A storage case 5 in which system piping and the like are arranged is formed.

Reference numeral 6 denotes an emergency water supply apparatus. As shown in FIG. 2, the emergency water supply apparatus 6 has a plurality of tubular members 7 installed laterally inclined to one side and a plurality of the tubular members 7. The frame body F is formed by a pair of side plates 8 and 9 connecting and holding both ends of the member 7.
In the inside of the side plates 8 and 9, there is formed a communicating portion described later so as to communicate between the vertically adjacent tubular members 7.

The inner surfaces of the plurality of tubular members 7 are formed of stainless steel or the like suitable for rust prevention, and both ends thereof are liquid-tightly connected and held by side plates 8 and 9. The side plates 8 and 9 will be described in more detail with reference to FIG. (A) of FIG. 3 and FIG.
As shown in (b) and (b), the side plates 8 and 9 are formed by joining two plates, holding plates 8a and 9a and communication plates 8b and 9b, respectively, in a liquid-tight manner. Through holes 11 are formed at predetermined intervals so that both ends of the tubular member 7 can be inserted, and both ends of the tubular member 7 inserted into the through hole 11 are sealed by O-rings 12. There is.

The communication plates 8b, 9b will be described later on the joint surface with the holding plates 8a, 9a as shown in FIG. 4 (b) showing the AA sectional view of FIGS. 3 and 4 (a). An oval shallow groove 13 serving as a communicating portion and an oval deep groove 14 serving as a communicating portion are formed below the shallow groove 13 respectively.
3 and the deep groove 14 are alternately arranged at equal intervals on the communication plates 8b and 9b.

The shallow grooves 13 and the deep grooves 14, which are alternately formed on the communication plate 9b on one side, have the opposite arrangement relationship with the corresponding communication plate 8b on the other side.

The side plates 8 and 9 on both sides are holding plates 8a,
9a and the communication plates 8b and 9b are liquid-tightly joined together using an adhesive or a bolt 15 to be integrated, and both ends of each tubular member 7 are inserted until they contact the joint surface of the communication plate 9b. It is inserted tightly. As a result, both ends of the plurality of tubular members 7 are connected and held by the side plates 8 and 9 to form the frame body F.

The shallow groove 13 and the deep groove 14 in the side plates 8 and 9 are, as shown in FIGS. 3 and 4A and 4B, a communication for connecting the upper and lower tubular members 7 and 7 at both ends. End portions of the respective tubular members 7 which form a portion and which are opposed to the position of the deep groove 14 which is a communicating portion between the inlet 16 of the lower tubular member 7 and the drainage port 17 of the upper tubular member 7, Are connected by the shallow groove 13 which is a communication portion of a passage having a flow resistance larger than that of the above.

As described above, the oval shallow groove 13 is formed as a slit-shaped communication portion H having a large flow resistance for connecting the upper and lower tubular members 7, 7, and the oval deep groove 14 located therebelow. Is configured as a communication portion R having a low water flow resistance that connects the lowermost end portion of one end of the upper tubular member 7 and the uppermost end portion of one end of the lower tubular member to communicate with each other.

In the frame F constructed as described above, the side plates 8 and 9 of one side plate 9 holding one end of the tubular member 7 at the lowermost end are lower than the tubular member 7 and the other side plate 8 is smaller than the other side plate 8. Each tubular member 7 that is connected and held by extending it for a long time
Are arranged to be inclined in one direction.

In this state, the frame body F is housed in a frame 18 formed in a rigid rectangular box shape in a state of being inclined to one side, and the emergency water supply device 6 is constructed. As shown in FIG. 1, the emergency water supply device 6 configured as described above has a sink portion 3
It is installed in the storage box 5 below.

As shown in FIG. 3, a water pipe 19 is connected to the side plate 9 on one side of the emergency water supply device 6 to the inlet 16 at the upper part of the communication plate 9b which communicates with one end of the uppermost tubular member 7. The communication pipe 20 connected to the water supply currant 4 shown in FIG. 1 is connected to the discharge port 17 of the tubular member 7 located at the lowermost end of the other side plate 8, and the flexible pipe branched from the communication pipe 20 is connected. A water tap 22 is attached to the pipe 21. In addition,
Although not limited to the water pipe 19, the air valve 10 is attached at the highest position in the vertical direction.

Here, the important point is that the opening area of the communicating portion R in the side plates 8 and 9 is larger than the opening area of the communicating portion H as shown in FIG. Most of the tap water to be flowed to the left and right in the adjacent tubular member 7 via the communication portion R sequentially while flowing down to the drainage port 17 at the lowest end, and the communication pipe 2 connected to the drainage port 17
It is drained from the water supply calan 4 via 0.

As described above, the tap water is used to sequentially flow the water, and the water is always secured in the running water channel formed by these tubular members in the state where there is no dead water.
That is, even in the event of an emergency, for example, when the water pipe is ruptured due to a time interruption of water supply or an earthquake, the water pressure is lost and water supply is interrupted.

Here, if water in the running water channel is desired, almost all the water in the tubular member can be discharged by simply opening the water tap 22. The reason is that the air valve 10 is closed by the water pressure constantly applied to the inside of the pipe, but when the water pressure from the upstream is released, the air valve 10 is automatically opened to introduce the atmosphere into the flowing water channel. To be done. Therefore, the tap water in each tubular member 7 communicating through the communication portion H is released from the restraint due to the negative pressure, flows down sequentially from the top by the weight of the water, and flows out from the water tap 22 through the drain port 17. Will be done.

Further, the opening area of the communicating portion H having a large flow resistance is such that the drain port 17 of the single tubular member 7 and the other inlet port 1
6 is smaller than the opening area of the communication portion R that communicates with 6, and almost does not flow into this communication portion H during normal use of water, but when the tubular member 7 is tilted in an emergency, the downstream side The communication part H allows the remaining water to flow downward through the tubular member 7
And the communication portion H on the upstream side contributes to the flow of air.

When most of the water in the emergency water supply system 6 is used and tap water again flows from the upstream side and flows into the tubular member 7, the air existing at the uppermost part of the drainage port and the inlet port. The air is efficiently discharged from the air valve 10 via the air valve, and the problem of water hammer etc. when using tap water is eliminated.

Further, since the communicating portion H for communicating between the adjacent tubular members 7 is formed in the side plates 8 and 9 in the shape of a slit by the shallow groove 13, fine particles such as red rust that have been washed away for a long time are formed. Even if the slit is clogged, since it is partial, the communication part H is not immediately clogged and blocked.
