Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an outflow device that automatically flushes flush water into a urinal.

Conventionally, the method for flushing a urinal has generally been manual, in which the user opens the valve himself by pressing a button or the like.

In this case, the user often does not operate the toilet bowl, which is inconvenient and leaves the toilet bowl dirty, which poses a hygiene problem.

Also, if you forget to turn off the faucet, the water will flow and leave unused, which is wasteful and uneconomical.

In addition, in order to keep the toilet bowl clean at all times, a method has been used in which a constant amount of water is flushed at all times, but this method has problems in terms of water conservation and is also extremely wasteful.

Furthermore, there are methods using electronic control such as optical sensors,
This requires a constant supply of current, which poses a problem in terms of power saving, and also has the disadvantage that it cannot be used in areas without electricity, and is also likely to cause malfunctions.

In view of these drawbacks, this invention was made by considering a method of automatically operating the urinal automatically by a mechanism without using electricity. The purpose of this device is to provide an automatic flushing water draining device for a urinal that is simple in construction and reliable in operation by using an actuating receiver and utilizing the actuation of the receiver and the closing means provided on the receiver. It is.

In order to achieve the above object, this invention forms a sealed tank by a water reservoir and an elevating bowl body inside the water reservoir, and the small hole bowl body is adapted to be constantly pulled upward. A siphon pipe for supplying water from the water tank is installed on the inside of the water storage tank, and an outlet of a water pipe with a water level control valve is formed at the lower part of the tank, and an outside air intake pipe is connected to the elevating bowl. The outflow pipe is curved into an inverted U shape, and then its lower end is connected to the upper part of the urinal, and a receiver for storing wastewater is arranged at the end of the drain opening of the urinal. The receiver is supported by a support device that is activated when the stored amount reaches a predetermined weight, and the lower end of the outside air suction pipe is opened when the receiver moves forward and closed when the receiver moves backward. This is an automatic flush water flushing device for the toilet bowl.

The details of this invention will be explained below with reference to drawings based on embodiments.

FIG. 1 is an explanatory sectional view showing an embodiment of the invention.

(1) is a water reservoir that stores water inside, and (2) is an elevating bowl made by hanging the container upside down, with a small hole bowl inserted into the water reservoir. , a vacuum section is formed that is filled with water and sealed from the outside air. A lobe (3) is provided at the top of the elevating bowl body, and is connected to a weight (5) via a pulley (4).Since the weight (5) is slightly heavier, it must be balanced at the appropriate time. It looks like this. A stopper (6) is provided at the lower part of the elevating bowl body, and is engaged with a stopper (7) provided inside the water reservoir, thereby preventing mutual separation.

A siphon pipe (8) is used in the water reservoir (1), and water is supplied from the water reservoir (9) into the water reservoir through the siphon pipe. Bottom wall (1) of water reservoir (1)
Connect the water pipe (10) to a). The water pipe (10) is
Its upper end (10a) is opened into the water reservoir (1), and in the middle thereof it is curved upward in an inverted U shape to form a water reservoir (10b), and its lower end (10c) is opened into the urinal (1). 1
1) There is a frontage at the top.

The lifting bowl body (2) has an upper end (1
2a) is opened in the lifting bowl (2) or the water reservoir (1), and the lower m (12b) of the outside air intake pipe is
Urinal (11) (7) Receiver formed at the tip (13)
It is opened at the position of .

The receiver (13) is provided at the tip of the urinal (11) and is rotatable by a support device (14).

That is, the middle part of the working shaft (14a) is rotatably indicated by a pin (14b), a receiver (13) is connected to one end of the working shaft (14a), and a weight (14c) is connected to the other end. It has become.

This weight (14c) is movably connected to the operating shaft (14a), and when the drainage water flowing into the receiver (13) reaches a predetermined amount, the operating shaft (14a) is Rotates clockwise, and this rotation causes the receiver (13)
is lowered and tilted to discharge the waste water in the receiver (13) to a predetermined amount or less. The receiver (13) is provided with a closing means for closing the lower end (12b) of the outside air suction pipe (12) to isolate it from the outside air. For example, as this blocking means, a protrusion (15) is formed in the receiver (13), and an outside air intake pipe is inserted into the protrusion (15) to prevent water from entering the protrusion (15). , the lower end (12b) of the outside air suction pipe should always be submerged.

In an embodiment having such a configuration, its operation will be explained.

First, in the state shown by the solid line in the drawing, by urinating into the urinal (11), this urine flows down from the drain port (lla) and is stored in the receiver (13) below. As a result, the weight of the receiver (13) increases, and when this exceeds a predetermined weight, the receiver (13) rotates counterclockwise in the figure around the bottle (14), opening the drain hole (lla) and removing the outside air. The lower end (12b) of the suction pipe (12) is a female pipe directed downward. As a result, the lower end (12b) is placed under the receiver (
13) is opened from the drainage surface (t3a) and communicates with the outside air, and the outside air is sucked from the lower end (12b), and the outside air suction pipe (12b) is opened.
2) Outside air flows into the sealed chamber from the upper end (12a). As a result, the negative pressure in the sealed chamber is eliminated, and the flushing water in the sealed chamber flows out into the urinal (11) through the outflow pipe (10), cleaning the inside of the urinal (11) while cleaning the inside of the urinal (11). lla)
is discharged from.

The washing water discharged from the outlet (ll'a) is sent to the receiver (ll'a).
13) Excess washing water that flows into the container (13) and maintains the above-mentioned movement of the receiver (13) is discharged from the receiver (13), overflows, and flows out toward a drain pipe (not shown). When the water level in the sealed room falls to a certain level, the Bollu Tap (16)
closes the upper end (10a) of the outflow pipe (10) and stops drainage.

In this case, if a magnet or the like is attached to the upper end (10a) of the pole tap (16) or the water pipe (10), the pole tap will immediately float up when the water level in the sealed chamber rises.
) can prevent the water in the tank from flowing out. When the drainage water stops flowing into the receiver (13), the weight of the receiver (13), which was tilted downward, becomes less than a predetermined value, and due to the action of the weight, the receiver (13) rotates clockwise in the figure and returns to its original position. to return to the equilibrium state. With the return of the receiver (13), the lower end (12b) of the outside air intake pipe (12) is connected to the receiver (13).
Trapped in water and cut off from the outside air.

On the other hand, outside air enters the sealed room from the outside air intake pipe (12) (12a
), the elevating bowl body is suspended by the lobe (3) via the pulley (4) due to the action of the weight (5), so the balance is lost and the elevating bowl body rises. The stopper (6) is the stopper (
7). In addition, the water level will drop as water flows out through the water supply pipe (10), but when the water level drops, water will flow from the water reservoir (9) into the water reservoir by the action of the siphon pipe (8). The water flows in, and the elevating bowl body (6) is pulled upward until it stops at the stopper (7) of the elevating bowl body (6), and at the same time, the water supply is stopped.

After the water supply into the water reservoir is completed, the inside of the airtight container is maintained in a completely airtight state and set to an initial state.

In the drawing, the water pipe (10) is curved into a mountain shape, and an air pipe is connected to the top of the pipe. This prevents cleaning water from accumulating in the water pipe leading to the water flow pipe (IOC), i.e., when the water flow is stopped.
The purpose is to prevent the occurrence of a siphon effect within the water pipe (10), that is, to prevent the wash water from flowing out from the water pipe (10) for a long time.

Next is the support device (14), which is initially shown as a solid line. In other words, until the wastewater flowing into the receiver (13) reaches a predetermined amount, the receiver (14C) maintains a horizontal state due to the action of the weight (14C), but when the wastewater reaches a predetermined amount, the receiver (13) As the weight increases, the working tube (14a) rotates counterclockwise in the figure around the axis of the support bottle (14b), and as a result, the receiver (13) and the working shaft are in the state shown by the broken line. tilt. As a result, the waste water inside the receiver (13') is discharged, the weight of the receiver (13) decreases rapidly, and the action shaft (13a) rotates clockwise in the figure due to the action of the weight (13c). will be returned to its initial position.

Note that a part of the liquid in the receiver (13) remains without flowing out even in the state shown by the broken line. Therefore, even when the original horizontal state is restored, the liquid naturally remains, and the tip (12) of the outside air intake pipe (12) remains.
b) is closed by the convex portion (15) and inserted into the liquid again to prevent outside air from entering.

As is clear from the above embodiments, according to the configuration of the present invention, the lower end of the outside air suction pipe for replenishing outside air into the sealed room is a receiver rotatably equipped at the tip of the drain hole of the urinal. Since it is opened and closed by the reciprocating movement of the receptacle with the closing means provided on the receptacle, it is automatically and reliably opened and closed.

Therefore, the structure is simple and the flushing water outflow device of the urinal can be operated reliably, and since it is not electrically operated, it can be manufactured at low cost and there is no risk of accidents.

As described above, the automatic urinal cleaning device of the present invention has excellent features such as being able to be used in places without electrical equipment because it is entirely mechanical.

Although the present invention has been described in the case where the operating shaft is supported by a pin as a support device, the present invention is not limited to this. For example, as shown in FIG. 2(a), the operating shaft may be supported by a flat spring or the like. It may be a structure in which one end is supported like a cantilever by an elastic body, or a structure in which both ends are supported by two coil springs with different elastic moduli as shown in FIG. 2(b). Alternatively, as shown in FIG. 2(C), the structure may be placed on a sponge-like elastic body.

Further, although the outflow pipe is provided on the bottom wall of the water reservoir, it may be provided on the side wall. Although the elevating bowl body is suspended by a robe, it goes without saying that it may also be lifted by a balance.
