Description

  The present invention relates to a cleaning apparatus provided with a vacuum breaker valve (vacuum breaker).

  Conventionally, the water supply device of the cleaning device has a negative pressure in the water stop valve portion that opens and closes the water supply passage from the outside and the primary water passage of the water stop valve portion in the middle of the water passage from the external water pipe to the cleaning means A vacuum breaker valve (vacuum breaker) that opens the secondary side water channel of the water stop valve to the atmosphere and a waste water discharge port for holding the secondary side water channel of the water stop valve unit below a certain water pressure is provided. In addition, a configuration in which the vacuum break valve portion and the waste water discharge port are combined into one unit is common (see, for example, Patent Document 1).

FIG. 6 shows a water circuit in the cleaning apparatus, and FIG. 7 shows details of a conventional structure around the vacuum breaker valve. The cleaning water supplied from the water pipe 1 is introduced into the vacuum breaker valve unit 4 through the water supply channel 2 and the water stop valve unit 3. The upstream side of the water stop valve portion 3 is called a primary side water channel, and the downstream side of the water stop valve portion 3 is called a secondary side water channel. The vacuum breaker valve portion 4 is provided with an inflow port 5 and an outflow port 6 for washing water, a waste water discharge port 7 and an air inflow port 8. The washing water that has exited from the outlet 6 is supplied to the washing means 10 by the water pump 9. The cleaning means 10 is provided with a nozzle portion 11 that moves forward when cleaning the local area of the human body. The nozzle portion 11 moves rearward and is stored in the main body of the cleaning device after the ejection of the cleaning water is finished. It has a structure. The waste water discharge port 7 has a role of discharging excess water into the toilet to wash the local area of the human body with a stable water pressure, and maintaining the secondary side water channel of the water stop valve portion below a certain water pressure. Yes. The purpose of the vacuum break valve unit 4 is that the cleaning device is immersed in the sewage in the toilet and the sewage flows into the water pipe when the water pipe 1 and the water supply channel 2 become negative pressure. When the secondary side water circuit becomes negative pressure, the valve 12 falls downward and the outside air is taken in from the air inlet 8 so that the secondary side water passage is opened to the atmosphere. The sewage flowing backward from the cleaning means 10 side does not reach the upstream side from the vacuum break valve part 4.
JP 2001-026963 A

  However, in the above-described conventional configuration, the stop valve 3 is closed when the ejection of the washing water is finished, and the supply of the washing water by the water pump 9 is stopped, and at the same time, the nozzle portion 11 moves rearward and is stored in the washing apparatus body. At that time, the water pressure of the secondary side water passage becomes low at the same time, and at the same time, the valve portion 12 of the vacuum breaker valve portion 4 moves downward to introduce outside air. As a result, the cleaning water remaining in the water passage is removed. Since it is pushed out to the nozzle part 11 side at atmospheric pressure, the ejection of the washing water cannot be stopped instantaneously, and the nozzle part 11 moves backward and the part other than the local part of the human body is unintentionally wetted. Had.

  The present invention solves the above-mentioned conventional problem, the phenomenon that the ejection of cleaning water from the nozzle portion generated by the outside air flowing into the vacuum break valve portion provided in the middle of the water channel can not stop instantaneously, The purpose is to prevent easily by devising the internal structure of the vacuum break valve part.

  In order to solve the above-described conventional problems, the cleaning device of the present invention has an air inlet, a waste water outlet, and a cleaning water outlet sequentially arranged from above in a vacuum breaker valve provided in the middle of the secondary water channel. Further, the vacuum breaker valve portion is provided with a rod body that is movable in a water flow.

  Accordingly, when the supply of the washing water is stopped, the rod body closes the washing water outlet, and the ejection of the washing water from the nozzle can be stopped instantaneously.

  When the cleaning water supply of the present invention is stopped, the spray of the cleaning water from the nozzle portion is instantaneously stopped, so that a part other than the local part of the human body is not unintentionally wetted and is comfortable. Can be provided.

  A first aspect of the present invention is a cleaning means for cleaning a local part of a human body and a water channel in the middle of a water channel, an air inlet for taking in outside air when the water channel becomes negative pressure in the middle of the water channel, A vacuum break valve unit having a discharge port and a cleaning water outlet for supplying cleaning water to the cleaning means side is installed, and the air inlet, the waste water discharge port, and the cleaning water outlet are sequentially arranged from above. The vacuum break valve portion is provided with a rod that is movable in a water flow. With such a configuration, the washing water in the water channel tends to be pushed out to the outlet side by the outside air flowing in from the air inlet when the washing is stopped, but the rod body temporarily blocks the outlet. Since the movement is hindered by moving to a position where the state is reached, there is an advantage that the ejection of washing water from the nozzle portion can be stopped instantaneously.

  In the second invention, in particular, in the first invention, the shape of the rod disposed inside the vacuum breaker valve portion is made substantially cylindrical, thereby stably realizing the action of the first invention. It is possible to make it.

  In particular, in the second invention, the third invention is such that, in the second invention, the diameter of the substantially cylindrical rod disposed inside the vacuum break valve portion is equal to or larger than the opening size of the washing water outlet, thereby The effect of the first aspect of the present invention in which the washing water outlet is in a closed state is sufficiently exhibited.

  According to a fourth aspect of the invention, in particular, in the second or third aspect of the invention, the washing water outlet is provided when the supply of the washing water to the water channel is stopped for the substantially cylindrical rod body arranged inside the vacuum break valve portion. By providing a recess on the surface of the rod body above the portion to be closed, the cleaning water is supplied, and in a state where there is a water flow to the discarded water outlet, the rod body stably exists in a position that does not block the washing water outlet. Effects can be obtained.

  In the fifth aspect of the invention, in particular, the concave portion provided on the surface of the rod of the fourth aspect is formed into a continuous groove shape, whereby the action of the fourth aspect of the invention can be stably realized. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows the details of the structure of the vacuum breaker valve portion of the cleaning apparatus according to Embodiment 1 of the present invention, and FIGS. 2 and 3 show the aa cross-sectional view of the vacuum breaker valve portion shown in FIG. is there. In addition, since the water circuit of the whole washing | cleaning apparatus is the same as FIG. 6, it uses together.

  The vacuum breaker valve portion 4 is provided with a cleaning water inlet 21, a cleaning water outlet 22, a discarded water discharge port 23, and an air inlet 24. The air inlet 24, the waste water outlet 23, and the washing water outlet 22 are sequentially arranged from above, and there is a valve portion 25 between the air inlet 24 and the waste water outlet 23. It has a structure that can move freely in the direction.

  In a state in which cleaning water is ejected from the nozzle portion 11, that is, in a state in which water flow is supplied from the cleaning water inlet 21, there is a water flow to the discarded water discharge port 23 as shown in FIG. Since 25 is pressed upward and the valve is closed, outside air is not introduced from the air inlet 24.

  Since the rod body 26 is installed inside the vacuum break valve portion 4 and is movable in the water stream, the periphery of the rod body 26 is always viewed from below when the water stream is supplied from the cleaning water inlet 21. Since there is a water flow that flows upward, the rod body 26 is positioned substantially at the center of the tubular main body 27 of the vacuum break valve portion. For this reason, the cleaning water outlet 22 is not blocked by the rod body 26, and a stable amount of water and cleaning water having a hydraulic pressure are supplied to the cleaning means 10 and the nozzle portion 11 side.

  Next, at the moment when the ejection of the washing water from the nozzle portion 11 is finished, the water flow from the washing water inlet 21 is stopped by closing the water stop valve 3, so there is no water flow to the discarded water discharge port 23, Further, since the valve portion 25 falls downward due to its own weight and enters a valve open state, the outside air is introduced from the air inlet 24 and the water inside the tubular body 27 of the vacuum breaker valve portion is discharged to the washing water outlet so as to be pushed out to the atmospheric pressure. Try to flow in the direction of 22.

  However, at this time, the rod 26 is pushed out toward the washing water outlet 22 because the water flow that has been flowing upward around the rod body is stopped, and moves to the position shown by 28 in FIG. Has the effect of making the state of obstructive. As a result, the ejection of the cleaning water remaining in the water channel from the nozzle part 11 is stopped instantaneously, and the part other than the local part of the human body is intended while the nozzle part 11 moves backward and tries to be stored in the main body of the cleaning device. It is possible to prevent wetness without being performed.

  At this time, the rod body 26 is movable in the water flow inside the tubular body 27 of the vacuum breaker valve portion, and in order to rotate the shaft, which part of the surface of the rod body 26 faces the cleaning water outlet 22 is restricted. Can not do it. For this reason, by making the shape of the rod body 26 into a substantially cylindrical shape, it is possible to always have a stable blocking effect of the washing water outlet 22.

  Further, the diameter D of the rod body 26 having a substantially cylindrical shape is set to be equal to or larger than the opening dimension d of the washing water outlet 22. When the diameter D of the rod body 26 is smaller than the opening dimension d of the washing water outlet 22, even when the rod body 26 moves to the position closest to the washing water outlet 22 as shown in FIG. A sufficient gap is not obtained because the gap between the outlet and the outlet becomes large. By setting D ≧ d, it is possible to have a stable blocking effect of the washing water outlet 22.

(Embodiment 2)
FIG. 4 shows a perspective view of a rod body according to the second embodiment of the present invention, and FIG. 5 shows a perspective view of another shape of the rod body.

  This embodiment is different from the first embodiment in that a rod body 29 having a substantially cylindrical shape as shown in FIG. 4 has a groove shape on the rod body surface 31 above the portion 30 that closes the washing water outlet 22. It is a point provided with the recessed part 32 of this. By providing the recess 32, the cleaning water is supplied, and in the state where there is a water flow flowing from the lower side to the upper side around the rod body 29, the flow of the surrounding water is uniformly rectified by the recess, thereby The body 29 is stably present at a substantially central position with respect to the tubular main body 27 of the vacuum breaking valve portion so as not to block the washing water outlet 22, and the effect that the water flow can be stabilized can be obtained.

  Further, as another shape of the recess, by providing a spiral groove-shaped recess 34 in the rod 33 as shown in FIG. 5, the rod 33 is rotated by a water flow from the lower side to the upper side, and is more reliably tubular. It will exist stably in the substantially central position with respect to the main body 27, and a more stable water flow can be obtained.

  As described above, since the cleaning device of the present invention can instantaneously stop the ejection of cleaning water, it can be applied to the use of a cleaning device used in an open space such as bathroom cleaning.
