TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water stopcock device for supplying and stopping water to a washroom or a toilet.
[0002]
[Prior art]
2. Description of the Related Art A conventional water stopcock device provided with a filter includes, for example, a cylindrical filter 106 mounted on a lid 106 wrapped around a shaft of an on-off valve 103 as shown in FIG. Numeral 105 is coaxial with the axis of the on-off valve 103. When the filter 106 is removed and the on-off valve 103 is opened and closed, the axes of the lid 105 and the on-off valve 103 rotate independently.
[0003]
Further, the operation of removing the filter 106 and the operation of opening and closing the on-off valve 103 are performed by using a tool such as a screwdriver or a special tool with a groove or the like provided on the shaft of the lid 105 and the on-off valve 103.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, in the event that a water leak accident occurs downstream of the on-off valve, even if the on-off valve 103 is to be closed, flood damage will spread while searching for a driver or a special tool, and damage to the surrounding floor and walls will occur. Not only that, if an accident occurs upstairs, it will also damage downstairs.
[0005]
Also, when cleaning the filter 106 due to dust clogging, the lid 105 can be removed without closing the groove of the lid 105 by the axis of the on-off valve 103 without necessarily closing the on-off valve 103 completely. There is a problem that when the lid 105 is accidentally opened without completely closing the valve 103, water is blown out.
[0006]
The present invention has been made in order to solve the above problems, and an object of the present invention is to be able to immediately close an on-off valve even if a water leakage accident occurs downstream of the on-off valve, It is an object of the present invention to provide a water stopcock device in which the lid of the filter is not removed when the filter is opened.
[0007]
[Means, actions and effects for solving the problem]
In order to achieve the above object, according to the present invention, there is provided a water stopcock device having an on-off valve for opening and closing a passage, a lever handle for operating the on-off valve, and a filter for preventing dust from flowing downstream. When the on-off valve is open, the lever portion of the lever handle is oriented in the direction in which water flows.
[0008]
According to the invention, since the lever handle is provided for improving the operability of the on-off valve, the on-off valve can be immediately closed even if a water leak accident occurs downstream of the on-off valve. Damage can be minimized, and when the open / close valve is open, the lever section of the lever handle is oriented in the direction of water flow. If it is facing in the direction of water flow, it can be visually judged that the on-off valve is open, so if you close the on-off valve and then remove the filter lid, water will erupt accidentally Can be prevented.
[0009]
According to a second aspect of the present invention, in the water stopcock device including an on-off valve for opening and closing a passage, a lever handle for operating the on-off valve, and a filter for preventing dust from flowing downstream, the on-off valve is opened. At least, the lever portion of the lever handle and the lid of the filter overlap at least partially.
[0010]
According to the invention, since the lever handle is provided for improving the operability of the on-off valve, the on-off valve can be immediately closed even if a water leak accident occurs downstream of the on-off valve. Damage can be minimized, and when the on-off valve is open, the lever part of the lever handle and the filter lid are at least partially overlapped, so that the lid is removed by filter cleaning etc. When the on-off valve is open, if the lever and lid are overlapped, the lever will be in the way when the lid is removed with a tool, so close the on-off valve so as not to interfere and then remove the filter lid By doing so, it is possible to prevent water from spouting by mistake.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 is a schematic configuration diagram of a water stopcock device showing an embodiment of the present invention.
Water flows in from the lower part of the main body 1 and flows out of the upper part of the main body 1 through the on-off valve 3 and the filter 6. The on-off valve 3 and the lever handle 2 are fastened with bolts 4, the filter 6 is mounted on the lid 5 by press fitting, and the lid 5 is fixed to the main body 1 by screwing.
[0013]
The on-off valve 3 is opened when the lever portion of the lever handle 2 is turned in the direction in which water flows (upward in FIG. 1), and is turned clockwise by about 90 degrees from the direction in which water flows (rightward in FIG. 1). ) To close.
[0014]
The on-off valve 3 and the filter 6 are brought as close as possible so that when the on-off valve 3 is opened, the lever portion of the lever handle 2 and the lid 5 of the filter 6 at least partially overlap.
[0015]
When removing the filter 6 by cleaning or the like, the lid 5 is removed by inserting a screwdriver or a special tool into, for example, a groove provided in the lid 5 and rotating the filter.
[0016]
As described above, the provision of the lever handle 2 for improving the operability of the on-off valve 3 allows the on-off valve 3 to be immediately closed even if a water leak accident occurs downstream of the on-off valve 3, Inundation damage can be minimized.
[0017]
When the on-off valve 3 is open, the lever portion of the lever handle 2 is directed in the direction of water flow, so that when the cover 5 is removed for cleaning the filter 6 or the like, the lever portion flows in the direction of water flow. , The on-off valve 3 can be visually judged that the on-off valve 3 is open. Therefore, if the on-off valve 3 is closed and then the lid 5 of the filter 6 is removed, water is spouted by mistake. Can be prevented.
[0018]
Alternatively, when the on-off valve 3 is open, the lever portion of the lever handle 2 and the cover of the filter 6 are at least partially overlapped with each other, so that when the cover 5 is removed for cleaning the filter 6 or the like. When the lever 3 and the lid 5 are overlapped with each other when the lever 3 is open, the lever is obstructed when the lid is removed with a tool. Therefore, the on-off valve 3 is closed so as not to be obstructed. By having the user remove the water, it is possible to prevent water from spouting by mistake.
[0019]
In the above-described embodiment, the on-off valve 3 is arranged on the lower part of the main body 1 and the filter 6 is arranged on the upper part of the main body 1. However, when the inflow and outflow directions of water are the same as in the embodiment, the on-off valve 3 and the filter 6 are When the on-off valve 3 is opened, the lever portion of the lever handle 2 is oriented upward (in the direction in which water flows) or in the direction of the lid 5 of the filter 6 arranged on either side. For example, the position and direction of the on-off valve 3 and the filter 6 and the direction of the lever portion of the lever handle 2 when the on-off valve 3 is opened and closed are not limited.
[0020]
Further, in the above-described embodiment, the on-off valve 3 and the filter 6 are disposed integrally with the main body 1, but the main body 1 may be divided and the on-off valve 3 and the filter 6 may be disposed respectively.
[0021]
In the above-described embodiment, when the on-off valve 3 is opened, the lever portion of the lever handle 2 and the cover 5 of the filter 6 at least partially overlap with each other. May be overlapped so as to cover the entirety of the cover 5. In this case, the lid 5 cannot be completely removed when the on-off valve 3 is opened, so that water does not spout.
