Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning nozzle drive device for a so-called hot water flush toilet bowl equipped with a cleaning device, and is used in the housing-related industrial field.

[Conventional technology]

In recent years, so-called warm water flushing toilets have become popular, which clean the anus and the like in a hygienic manner by cleaning the anus and bidet with warm water, and drying the anus and the like with warm air if necessary.

And, as this kind of toilet bowl, for example,
There is something shown in 2. As shown in FIGS. 2 to 4, this toilet bowl is equipped with a cleaning nozzle that is normally stored inside the rear of a toilet bowl 101 equipped with a toilet seat 102 as shown in FIG. 3, and that extends during cleaning as shown in FIG. 4. A cleaning nozzle device is incorporated. In this cleaning nozzle device, a cleaning nozzle 107, which has a spout 109 at its tip and a seal ring 114 fitted at its base end, slides inside a movable cylinder 105, which has a seal ring 113 fitted at its base end. Furthermore, the movable cylinder 105 is arranged in a sliding relationship within the fixed cylinder 104, and between the movable cylinder 105 and the fixed cylinder 104 there is a water channel and a cleaning nozzle 107 for applying a load water pressure to restrict the advance of the movable cylinder 105. Water channels that apply load water pressure to advance the cleaning nozzle 107 and the movable cylinder 105 are connected to the interior thereof.

Then, the load water pressure is introduced into the cleaning nozzle 107 from the hot water tank by the pump 117 through the discharge port 119, one through the control valve 121 and the water pressure introduction port 111, and the other through the control valve 120 and the water pressure introduction port 110. It is configured to be introduced between the movable cylinder lO5 and the fixed cylinder 104. In addition, 116 is a heater, 117 is a pump, 11
8 is a suction port, and 125 is a thermoswitch.

In this device, when both control valves 120 and 121 are opened, water pressure is applied between the movable cylinder 105 and the fixed cylinder 104, and only the cleaning nozzle 107 moves forward due to the applied water pressure without moving the movable cylinder 105 forward. Washing becomes possible.

If only the control valve 121 is opened, the movable cylinder 105 and the cleaning nozzle 107 move forward together, as shown in FIG. 4, allowing bidet cleaning.

(Problems to be Solved by the Invention) As mentioned above, in the conventional warm water flushing toilet, cleaning can be controlled in two positions: anal cleaning and bidet cleaning, but the mechanical part has a fixed cylinder and a movable cylinder. The cleaning nozzle consists of three cylindrical bodies, and a movable cylinder and a spring for advancing and retracting the cleaning nozzle are housed between each cylinder, and a load that restricts the advancement of the movable cylinder is placed between the movable cylinder and the cleaning nozzle. Since it is necessary to provide a waterway to apply water pressure, the outside diameter of the fixed cylinder will inevitably become large. (The outer diameter of the fixed cylinder is 37 mm.) There are two types of hot water flush toilets: one with an integrated toilet bowl and one with a seat. In the case of the toilet seat type, it is necessary to incorporate all the mechanical parts of the warm water flush toilet into a narrow space. The height of the toilet seat must be at least large enough to accommodate the fixed cylinder, and considering that the fixed cylinder is generally fixed diagonally downward into the toilet bowl as shown in Figure 2. ,
It is not desirable for the fixed cylinder to have a large outer diameter.

In addition, springs are used for the movable cylinder and the cleaning nozzle to retreat, so when cleaning, especially when cleaning the bidet,
It is necessary to apply enough water pressure to resist both springs, and as a result, it has the disadvantage that it is difficult to use in areas with low water pressure.

Furthermore, when considering the expansion and contraction of each spring, each spring requires expansion and contraction allowance in the axial direction, which is not preferable in view of the toilet seat type hot water washer toilet which does not take up much storage space in the horizontal and vertical directions.

[Means for solving problems]

The present invention aims to solve the above-mentioned conventional problems, and its basic configuration includes a fixed cylinder, which slides in the axial direction within the fixed cylinder, and has a plurality of hot water receiving holes in the axial direction of the peripheral wall. a plurality of cleaning nozzle driving cylinders connected to the back side of the cleaning nozzle of the fixed cylinder, a hot water tank that supplies hot water to a hot water supply hole drilled in the peripheral wall of the fixed cylinder, the cleaning nozzle driving cylinder and the hot water; The system consists of a water supply system that supplies water to the link, and a plurality of cleaning nozzle drive cylinders are connected in parallel to a fixed cylinder, and each fixed cylinder has a valve body that advances in the axial direction with supplied water and retreats with a spring. A sealed chamber is formed by the secondary side of both valve bodies, the peripheral wall of the fixed cylinder, and the back surface of the cleaning nozzle, and an incompressible fluid is stored in the sealed chamber, and the cleaning nozzle is advanced by selectively driving the valve body. The cleaning nozzle drive device for a warm water flush toilet bowl is such that when the fixed cylinder peripheral wall is opened, a hot water supply hole drilled in the fixed cylinder peripheral wall selectively matches a plurality of hot water reception holes punched in the cleaning nozzle peripheral wall. be.

〔Example〕

FIG. 1 shows one embodiment of the present invention, in which water is branched from a water supply pipe 1 to a water supply pipe 2.3 via a main valve (2). The water supplied to the water supply pipe 2 branches into a first cylinder water supply valve V1 for driving the cleaning nozzle, a second cylinder water supply valve V2 for driving the cleaning nozzle, and a drain pipe 2', each of which has a first cylinder water supply valve for driving the cleaning nozzle. 21, leading to the second cylinder 24 for driving the cleaning nozzle.

On the other hand, the water supplied to the water supply pipe 3 has a cleaning strength dial v3.
The hot water enters the cleaning nozzle 5 through the hot water tank T, the hot water supply hole 42 formed in the peripheral wall of the fixed cylinder 4, and the hot water receiving hole 52 or 52' formed in the peripheral wall of the cleaning nozzle 5. Inside the first cylinder 21 for driving the cleaning nozzle, a valve body 22 is biased by a spring 23 in a direction against the water force from the first cylinder supply valve Vl for driving the cleaning nozzle, and is slidable in the axial direction. It is arranged. 22' is a lift control shaft that regulates the sliding distance of the valve body 22.

Similarly, a valve body 2 is installed inside the second cylinder 24 for driving the cleaning nozzle.
However, the lift control shaft 25' is longer than the lift control shaft 22', and the sliding distance of the valve body 25 is longer than the lift control shaft 22'.
It will be shorter than the sliding distance of 2.

The first cylinder 21 for driving the cleaning nozzle and the second cylinder 24 for driving the cleaning nozzle are assembled on the secondary side of each valve body 22.25, and are connected to the back wall communication hole 43 of the fixed cylinder 4 via the connecting pipe 20. is connected to. A closed chamber M is formed by the secondary sides of the valve bodies 22 and 25, the connecting pipe 20, and the back wall 51 of the cleaning nozzle 5, and an incompressible fluid is stored in the closed chamber M.

Since the volume (volume of the incompressible fluid) in the sealed chamber M remains unchanged, the cleaning nozzle 5 is moved back and forth by moving the valve body 22, 25 back and forth.

In the case of this embodiment, the two identical cleaning nozzle driving cylinders 21 and 24 are used, and the lifts of the valve bodies 22 and 25 are made different, thereby making the advancing distance of the cleaning nozzle 5 different. When the valve body 22 is driven, the hot water receiving hole 52 of the cleaning nozzle 5 is aligned with the hot water supply hole 42 of the fixed cylinder 4, and when the valve body 25 is driven, the hot water receiving hole 52 of the cleaning nozzle 5 is aligned with the hot water receiving hole 42 of the fixed cylinder 4. 52' corresponds to the hot water supply hole 42 of the fixed cylinder 4.

In the case of this embodiment, the cleaning nozzle driving cylinder 21°24
Although the structure is as described above, it is also possible to make the advancing distance of the cleaning nozzle 5 different by setting the valve body lift amount of each cylinder 21 and 24 to be the same and making the cylinder inner diameter different. As such, it is possible to drive only one cylinder for anal cleaning and to drive both cylinders for bidet cleaning, thereby varying the advancing distance of the cleaning nozzle.

In addition, in the case of this embodiment, the cleaning nozzle driving cylinder 2
Although 1 and 24 are constructed as an integral structure, it goes without saying that they can also be constructed as separate bodies.

In the case of the present invention, it is possible to set the advancing distance of the cleaning nozzle 5 to different preset distances using the cleaning nozzle driving cylinder for anal cleaning and bidet cleaning, and in this embodiment, the operation will be specifically explained. A brief explanation is as follows.

By turning on the cleaning switch (not shown),
The main valve V and the first cylinder water supply valve Vl for driving the cleaning nozzle are opened, and water is branched from the water supply pipe 1 to the water supply pipes 2 and 3 via the main valve V.

The water branched to the water supply pipe 2 is branched to the first cylinder 21 for driving the washing nozzle and the drain pipe 2' via the first cylinder water supply valve v1 for driving the washing nozzle, which is open.

The water branched and supplied to the first cylinder 21 for driving the cleaning nozzle presses the valve body 22, compresses the spring 23, and slides the valve body 22 until it is locked by the lift control shaft 22'. Since there is basically no change in the volume of the incompressible fluid in the sealed chamber M, the incompressible fluid presses the nozzle back surface 51 of the cleaning nozzle 5 due to the sliding of the valve body 22, and the hot water supply hole 42 of the fixed cylinder 4. The cleaning nozzle 5 is advanced to a position where the warm water receiving hole 52 of the cleaning nozzle 5 and the hot water receiving hole 52 of the cleaning nozzle 5 coincide with each other.

The water branched to the drain pipe 2' is placed in an appropriate place in the toilet bowl, and if possible, in a position where the cleaning nozzle 5 around the tip of the fixed cylinder 4 can be cleaned in order to keep the jet hole 53 of the cleaning nozzle 5 clean. Preferably, it is open.

On the other hand, the water supplied to the water supply pipe 3 has a cleaning strength dial v whose flow rate is adjusted in advance so that an appropriate amount of water can be supplied.
3 and flows into the hot water tank T. The hot water tank T stores hot water that is heated by a hot water heater and controlled to an appropriate temperature by a thermostat.
The hot water flows into the cavity in the cleaning nozzle 5 through the hot water supply hole 42 of the cleaning nozzle 5 and the hot water receiving hole 52 of the cleaning nozzle 5, and is ejected from an appropriate number of spout holes 53 formed at the tip of the cleaning nozzle 5.

By turning off the bidet cleaning switch (not shown), the main valve (2) and the first cylinder water supply valve V1 for driving the cleaning nozzle are closed, and the water supply to the water supply pipe 2.3 is stopped.

The water supply to the water supply pipe 2 is stopped, and the first cylinder water supply pulp v1 for driving the cleaning nozzle is closed, and the water supply to the first cylinder 21 for driving the cleaning nozzle is stopped. Since the first cylinder 21 for driving the cleaning nozzle is in communication with the drain pipe 2', the residual water in the first cylinder 21 for driving the cleaning nozzle is discharged from the drain pipe 2' by the return of the valve body 22 due to the restoration of the spring 23. being pushed out. At the same time, due to the return of the valve body 22, the volume of the sealed chamber M remains unchanged, so the cleaning nozzle 5 retreats into the fixed cylinder 4.

By turning on the anal washing switch (not shown),
The main valve V1 and the second cylinder water supply valve v2 for driving the cleaning nozzle are opened, and water is branched from the water supply pipe 1 to the water supply pipes 2 and 3 via the main valve V.

The water branched to the water supply pipe 2 is branched to the second cylinder 24 for driving the washing nozzle and the drain pipe 2' via the second cylinder water supply valve v2 for driving the washing nozzle, which is open.

The water branched and supplied to the second cylinder 24 for driving the cleaning nozzle presses the valve body 25, compresses the spring 26, and slides the valve body 25 until it is locked by the lift control shaft 25'. Since there is basically no change in the volume of the incompressible fluid in the sealed fM, the sliding of the valve body 25 causes the incompressible fluid to press against the nozzle back surface 51 of the cleaning nozzle 5 and to connect with the hot water supply hole 42 of the fixed cylinder 4. The cleaning nozzle 5 is advanced to a position where the hot water receiving hole 52' of the cleaning nozzle 5 coincides with the cleaning nozzle 5.

The water branched to the drain pipe 2' is placed in an appropriate place in the toilet bowl, and if possible, in a position where the cleaning nozzle 5 around the tip of the fixed cylinder 4 can be cleaned in order to keep the jet hole 53 of the cleaning nozzle 5 clean. Preferably, it is open.

On the other hand, the water supplied to the water supply pipe 3 has a cleaning strength dial v whose flow rate is adjusted in advance so that an appropriate amount of water can be supplied.
3 and flows into the hot water tank T. The hot water tank T stores hot water that is heated by a hot water heater and controlled to an appropriate temperature by a thermostat.
The hot water flows into the cavity in the cleaning nozzle 5 through the hot water supply hole 42 of the cleaning nozzle 5 and the hot water receiving hole 52' of the cleaning nozzle 5, and is ejected from an appropriate number of jet holes 53 formed at the tip of the cleaning nozzle 5.

By turning off the anal cleaning switch (not shown), the main valve (2) and the second cylinder water supply valve v2 for driving the cleaning nozzle are closed, and the water supply to the water supply pipe 2.3 is stopped.

The water supply to the water supply pipe 2 is stopped, the second cylinder water supply valve ν2 for driving the cleaning nozzle is closed, and the supply of water to the second cylinder 24 for driving the cleaning nozzle is stopped. Since the second cylinder 24 for driving the cleaning nozzle is in communication with the drain pipe 2', the residual water in the second cylinder 24 for driving the cleaning nozzle is discharged from the drain pipe 2' by the return of the valve body 25 due to the restoration of the spring 26. being pushed out. At the same time, due to the return of the valve body 25, the volume of the sealed chamber M remains unchanged, so the cleaning nozzle 5 retreats into the fixed cylinder 4.

〔Effect of the invention〕

By separately providing a cylinder for driving the cleaning nozzle, cleaning in two stages of anal cleaning and bidet cleaning can be achieved with one fixed cylinder and one cleaning nozzle.
It is possible to reduce the external size of the fixed cylinder compared to the conventional one.

Since no spring is used in the hot water supply system to the cleaning nozzle, it can be used in areas with low water pressure where conventional models cannot be used.

Conventionally, in order to remove the cleaning nozzle, a spring was interposed between the cleaning nozzle and a fixed cylinder, and the spring required unnecessary space for expansion and contraction in the axial direction.
In the present invention, since no spring is used between the cleaning nozzle and the fixed cylinder, it is possible to eliminate unnecessary space in the axial direction, and the space of the toilet seat-type hot water washer toilet, which is limited by the axial space, is greatly reduced. did it.
