Description

  The present invention relates to a ball tap that automatically supplies water into a washing tank that stores water for washing toilet bowls, and more particularly, includes an opening / closing drive mechanism that opens and closes a valve body of a water faucet in conjunction with the up and down movement of a float. Related to the ball tap.

  Conventionally, as a toilet flushing device, a faucet that feeds water into the washing tank, a float that moves up and down in conjunction with the water level in the washing tank, and a valve that opens and closes in conjunction with the up and down movement of the float Ball tap that has an open / close drive mechanism, for example, an open / close drive mechanism that includes a pivot arm that pivots in conjunction with the up-and-down movement of the float, and detects the water level in the wash tank with the float to keep the wash tank full. Is widely used.

FIG. 13 shows a conventional example of this kind of ball tap.
In the figure, 200 is a cleaning tank, 202 is a water tap for supplying water into the cleaning tank 200, 204 is a water discharge pipe that extends downward in the cleaning tank 200 and discharges water from the water tap 202 into the cleaning tank 200. It is.

Reference numeral 206 denotes a float disposed on the side of the water discharge pipe 204, and a connecting arm 208 extends horizontally from the float 206, and is guided up and down along the water discharge pipe 204 at the tip of the connection arm 208. The guide ring 210 is pivotally connected around a shaft 212.
Reference numeral 214 denotes a rotating arm that opens and closes the valve body of the water faucet 202 in conjunction with the up-and-down movement of the float 206. The distal end is connected to the float 206 and the base end is rotatably connected to the main body of the water faucet 202. ing.

In the ball tap shown in FIG. 13, when the water in the cleaning tank 200 is discharged and the water level is lowered, the float 206 moves downward, and accordingly, the rotating arm 214 rotates in the clockwise direction around the base end side. The valve body of the water tap 202 is opened by dynamic motion.
Here, the water tap 202 is opened, and water from the external water supply pipe is supplied into the cleaning tank 200 through the water discharge pipe 204.

When the water level rises along with this, the float 206 moves up in conjunction with this, and this time, the turning arm 214 turns counterclockwise in the figure.
As a result, the valve body is closed, the water tap 202 is closed, and water discharge from the water discharge pipe 204 is stopped.

However, in the case of the conventional ball tap shown in FIG. 13, since the float 206 is disposed on the side of the water discharge pipe 204, the washing tank is used to attach the float 206 and the rotating arm 214 and to secure their movement space. There is a problem that a large space is required in 200.
In recent years, there has been a demand for downsizing of the cleaning tank 200. On the other hand, with this type of ball tap, it is difficult to downsize the cleaning tank 200.

On the other hand, Patent Document 1 below discloses that a float is provided so that the water discharge pipe penetrates the float up and down, and the float is moved up and down using the water discharge pipe as a guide.
FIG. 14 shows a specific example thereof.

In the illustrated ball tap, the water discharge pipe 204 extends through the float 206, and the float 206 moves up and down using the water discharge pipe 204 as a guide.
Reference numeral 216 denotes a shaft that is inserted through the float 206, and a tip end portion of a rotating arm 218 is connected to an upper end portion of the shaft so as to be rotatable around the shaft 220.
A base end portion of the rotating arm 218 is attached to the main body of the water tap 202 and is configured to rotate up and down in the drawing around the attaching portion.

In the case of the ball tap shown in FIG. 14, when the float 206 is raised, the float 206 is brought into contact with a screw ring 224 that is screwed into the male screw 222 of the shaft 216. Here, the screw ring 224 is for adjusting the relative height position of the float 206 with respect to the shaft 216.
That is, the height position of the float 206 can be adjusted by shifting the screwing position of the screw ring 224 upward or downward along the shaft 216.

Now, when the float 206 rises and comes into contact with the screw ring 224, the shaft 216 rises together due to the buoyancy, causing the turning arm 218 to turn (clockwise turning in the figure), and the valve in the water tap 202. Open the body.
On the other hand, when the float 206 is lowered, the arm 218 rotates in the opposite direction (counterclockwise in the figure) to open the valve body of the water tap 202.

  As is apparent from the figure, in the case of this ball tap, a large space is not required in the cleaning tank 200 for the float 206 and the rotating arm 218, and therefore the cleaning tank 200 can be made compact.

  However, in the case of the ball tap shown in FIG. 14, it is difficult to convert the vertical movement of the float 206 into the smooth and stable rotational movement of the rotational arm 218. As a result, the valve body smoothly opens and closes in the water tap 202, that is, the washing tank. It is difficult to ensure stable water supply performance to the toilet, and there is a risk of causing poor cleaning of the toilet bowl.

  Therefore, a column is provided in a form that stands upward from the float, and a guide member that is separate from the column is fixed to the column so that the height can be adjusted, and the tip of the rotating arm can be slid with respect to the guide member. It is conceivable that the pivoting arm is pivotally moved by the sliding motion of the tip of the pivoting arm.

By doing in this way, it becomes possible to make a rotation arm rotate more stably by the raising / lowering movement of a float.
As a means for erecting the column on the float, it is considered that one column member that is separate from the float is connected to the float with a connection clip. In this case, the column member and the connection clip are connected to the float. It is necessary as a separate part, and the number of component parts of the ball tap increases, and there is only one connection point to the float of the column member by the connection clip. The pillar tilts in the direction of rotation of the rotating arm or causes rattling with the location as a fulcrum, which causes the float movement or the rotational movement of the rotating arm to become unstable, water supply performance, water stopping performance, This causes a problem that the cleaning performance of the toilet bowl deteriorates.
As described above, the open / close drive mechanism includes a rotating arm, but this type of problem is transmitted to the open / close drive mechanism through the support column through the up / down motion of the float, and other general ball taps that drive the open / close valve body to open / close. Can occur in the same way.
