Technology Field

[0001] The present invention relates to an emergency water supply device that enables water supply even in the event of a failure of a water collection device for recovering and reusing water used in a bathroom. More specifically, it relates to an emergency water supply device for a water collection device designed to reuse water used in a bathroom as flushing water for a toilet, which allows the bathroom to be continuously used with tap water in the event that the water collection device cannot be used due to a failure of the mechanical devices for operating the water collection device. Background Technology

[0002] Conventional flush toilets are structured so that tap water flows into the toilet tank by connecting one end of a flexible hose to the angle valve and the other to a fill valve. In terms of ease of use, they have the advantage of being as trouble-free as current flush toilets; however, the problem was that there was no system in place to allow users to recycle the water, even if they wished to do so.

[0003] Accordingly, Patent No. 10-0929478 discloses a water collection device for reusing water used in a bathroom as flushing water for a toilet by cutting the middle point of a flexible hose among the parts attached to the flush toilet and attaching a T-elbow, connecting a first solenoid valve to the reusable water pipe in one of three directions to control the flow of water, connecting a second solenoid valve to the water supply pipe in the second direction, and connecting a toilet water tank in the third direction.

[0004] However, in utilizing and operating the aforementioned water collection device, failures frequently occur among any of the multiple mechanical devices driving the water collection device, and since it is difficult to utilize and operate the water collection device when these mechanical devices fail, a separate emergency water supply device becomes necessary.

[0005] The background technology or prior art mentioned herein is intended only to aid in understanding the technical significance of the present invention and does not refer to technology widely known in the technical field to which this invention belongs prior to the filing of the present invention.

[0007] The present invention improves upon the aforementioned problems and provides an emergency water supply device capable of simultaneously solving three problems: when the mechanical device forming the water collection device is normal and there is no reusable water in the storage tank, when the mechanical device is normal and there is reusable water in the storage tank, and when it is abnormal, that is, when the mechanical device fails. means of solving the problem

[0008] According to one embodiment of the present invention for achieving such objectives, a water supply pipe (6) for supplying water is connected to an upper inlet section (5a) configured at the top, a first discharge section pipe (51) is connected to a first inlet / discharge section (5b) configured on one side, a second discharge section pipe (52) is connected to a second inlet / discharge section (5c) configured on the other side, and a handle (9) for switching the direction of water flow depending on whether the water collection device is malfunctioning is configured as a three-way ball valve (5); A cross-shaped cross valve (8) having an upper inlet / outlet section (8a) formed at the top, a first side inlet / outlet section (8b) formed on the other side connected to the second discharge section pipe (52), a lower inlet / outlet section (8c) formed at the bottom connected to the end of the first discharge section pipe (51), and a second side inlet / outlet section (8d) formed on one side connected to the third discharge section pipe (81) connected to the toilet water tank (4); a backflow prevention valve (3) connected to the upper part of the upper inlet / outlet section (8a); a first solenoid valve (2) connected to the upper part of the backflow prevention valve (3); a second solenoid valve (7) connected to the first discharge section pipe (51); and a reusable water pipe (1) connected to the reusable water storage tank (20) of the water collection device. The invention is characterized by including a control unit (10) that receives a detection signal regarding the water level of the reusable water stored in the reusable water storage tank (20) from a low water level sensor (21) configured in the reusable water storage tank (20), and controls the opening and closing of the first and second solenoid valves (2, 7) according to the received detection signal.

[0009] According to one embodiment of the present invention, the control unit (10) is characterized by controlling the first solenoid valve (2) to open and the second solenoid valve (7) to close when the detection signal determines that there is reusable water in the reusable water storage tank (20).

[0010] According to one embodiment of the present invention, the control unit (10) is characterized by controlling the first solenoid valve (2) to close and the second solenoid valve (7) to supply water to the toilet tank (4) when the detection signal determines that the reusable water in the reusable water storage tank (20) has been depleted.

[0011] According to one embodiment of the present invention, when it is determined that a malfunction has occurred in the water collection device, the handle (9) is rotated downward so that the direction of the water flow is directed toward the second discharge pipe (52) and can be supplied to the water tank (4) of the toilet. Effects of the invention

[0012] The present invention is highly effective in that, in the event of a failure in the mechanical device constituting a water collection system for reusing bathroom water as flushing water for the toilet, water is supplied to the toilet tank just like the original flush toilet structure simply by rotating the handle of the three-way ball valve 90 degrees from the normal direction of the handle (Fig. 2), thereby enabling rapid reduction of emergency situations even when the operation of the water collection system is difficult.

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0018] As described above, the present invention comprises an emergency water supply device that operates when a water collection device fails to reuse water in a bathroom as flushing water for a toilet, and is composed of a first solenoid valve (2), a backflow prevention valve (3), a toilet water tank (4), a three-way ball valve (5), a second solenoid valve (7), and a cross valve (8).

[0019] More specifically, a water supply pipe (6) is installed in the upper inlet (5a) configured at the top of the three-way ball valve (5), and a first discharge pipe (51) is connected to the first inlet / discharge section (5b) configured on one side, and a second solenoid valve (7) is configured to be coupled to the first discharge pipe (51).

[0020] Here, the end of the first discharge pipe (51) is connected to the lower inlet / discharge section (8c) located at the bottom of the cross valve (8).

[0021] In addition, a second discharge pipe (52) is connected to a second inlet / outlet section (5c) configured on the other side of a three-way ball valve (5), and this second discharge pipe (52) is connected to a first side inlet / outlet section (8b) configured on one side of a cross-shaped cross valve (8).

[0022] This three-way ball valve (5) is configured so that when the direction of the handle (9) is rotated 90 degrees to the right, the water supplied through the water supply pipe (6) can flow to the second solenoid valve (7) side through the first discharge pipe (51).

[0023] The cross valve (8) is configured with inlet and outlet sections on the top, bottom, left, and right sides, respectively, and is configured with an upper inlet / outlet section (8a) configured on the top, a first side inlet / outlet section (8b) configured on the left, a lower inlet / outlet section (8c) configured on the bottom, and a second side inlet / outlet section (8d) configured on the right.

[0024] The cross valve (8) is configured with a backflow prevention valve (3) above the upper inlet / outlet section (8a), the first side inlet / outlet section (8b) is connected to the second discharge section pipe (52) of the three-way ball valve (5), and the lower inlet / outlet section (8c) is connected to the end of the first discharge section pipe (51).

[0025] Additionally, the cross valve (8) has a third discharge pipe (81) connected to the second side inlet / outlet section (8d), and the end of the third discharge pipe (81) is connected to the water tank (4) of the toilet.

[0026] The backflow prevention valve (3) is connected to the upper inlet / outlet part (8a) of the cross valve (8) at the bottom through a connecting pipe.

[0027] A first solenoid valve (2) is configured at the upper part of the backflow prevention valve (3) and is likewise connected through a connecting pipe.

[0028] The first solenoid valve (2) is connected to a reusable water pipe (1) at its upper end, and is connected to a reusable water storage tank (20) by this reusable water pipe (1).

[0029] In addition, the emergency water supply device of the present invention is configured with a control unit (10) that receives a detection signal from a low water level sensor (21) of a reusable water storage tank (20) and controls the operation of the first and second solenoid valves (2, 7) to turn them on / off.

[0030] The emergency water supply device configured in this way is configured so that when the water collection device operates normally, water is supplied to the first discharge pipe (51) of the three-way ball valve (5) and flows to the water tank (4) of the toilet. That is, the second solenoid valve (7) is kept in an open state.

[0031] In addition, when a signal indicating that there is reusable water is transmitted to the control unit (10) from the low water level sensor (21) of the reusable water storage tank (20) of the water collection device, the control unit (10) controls the first solenoid valve (2) to open and the second solenoid valve (7) to close, thereby enabling reusable water to be supplied to the toilet water tank (4).

[0032] Additionally, when the water collection device is operating normally and a signal is transmitted to the control unit (10) through the low water level sensor (21) indicating that the depletion of the water in the reusable water storage tank (20) is detected, the control unit (10) is configured to close the first solenoid valve (2) and simultaneously open the second solenoid valve (7) so that tap water can be supplied to the toilet water tank (4).

[0033] The control unit (10) repeatedly performs the aforementioned operation process when the water collection device is operating normally.

[0034] In addition, when it is abnormal, that is, when a failure of the water collection device occurs, as shown in FIG. 2, the handle (9) is rotated 90 degrees downward so that the direction of the water flow is directed toward the second discharge pipe (52) and can be supplied to the toilet water tank (4).

[0035] At this time, when the flow of water is directed toward the second discharge pipe (52), the first discharge pipe (51) is blocked, and the water cannot flow back regardless of whether the second solenoid valve (7) is opened or closed. Since the water supplied to the cross valve (8) through the second discharge pipe (52) can be prevented from flowing back toward the water supply pipe (1) by the backflow prevention valve (3), the water is supplied to the toilet water tank (4) in the same way as in the existing flush toilet structure.

[0036] The emergency water supply device of the present invention configured in this manner allows the toilet of the water collection device to be used at any time by repeatedly turning the first and second solenoid valves (2, 7) on and off according to the instructions of the low water level sensor (21) in the storage tank (20) when there is no mechanical failure, but when it becomes abnormal, the water supplied through the water supply pipe (6) is supplied to the cross valve (8) through the second discharge pipe (52), and the water is directly supplied to the water tank (4) of the toilet connected through the cross valve (8) and the third discharge pipe (81), thereby solving the problem of not being able to use the toilet even when the water collection device fails.

[0037] Meanwhile, the water collection device described in the present invention may be configured to include a water collection tank embedded in the indoor floor, a reusable water storage tank (20) equipped with a low water level sensor (21), and a pump that stores the reusable water recovered into the water collection tank in the reusable water storage tank (20).

[0038] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by these embodiments.
