Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a toilet booth whose wall surface can be washed with running water.

(Prior Art) Conventionally, it is known that a floor can be washed by generating a water flow on a floor surface provided with a toilet bowl each time it is used in a public toilet or the like or as needed.

(Problems to be solved by the invention) However, the cleaning of the wall surface of the toilet booth is performed manually, which is a time-consuming and troublesome work.

(Means for Solving the Problem) The present invention is provided with a nozzle for ejecting water for cleaning the side wall surface of a toilet booth.

(Operation) Water discharged from the nozzle flows down along the side wall surface,
The side wall surface is cleaned.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of a toilet booth according to the present invention, and FIG.
The figure is a structural diagram showing the main structure of the toilet booth.

In the toilet booth 1, the side wall unit 3 is built on the peripheral portion of the floor pan 2, the door frame 4 is provided in the front part of the side wall unit 3, and the door 5 is attached. On the right side of the door frame 4, there is provided an indicator light 6 for displaying the status such as in use and cleaning.

At least the floor surface or the inner wall surface of the floor pan 2 and the side wall unit 3 has waterproofness.
For example, it is an integrated structure product.

Next, the internal structure will be described with reference to FIG.

The toilet bowl 7 fixed to the floor pan 2 is connected to a water supply pipe 9 via a flush valve 8, and the lower portion of the toilet bowl 7 is connected to a drain pipe 10. The drain pipe 10 is connected to a drain port 11 provided in the floor pan 2, and the floor surface of the floor pan 2 has a running water gradient toward the drain port 11.

A plurality of shower nozzles 12 on the upper wall surface of the side wall unit 3
Is arranged in a direction in which flowing water ejected from the nozzle radiates to a wall surface facing the wall surface to which the nozzle is attached. The shower nozzle 12 ... Is connected to the nozzle water supply pipe 13, and is further connected to the water supply pipe 9 via an electromagnetic valve 14 that controls water supply to the shower nozzle. The solenoid valve 14 is connected to the control device 16 by a solenoid valve control line 15.

The control device 16 uses a sensor wire 17 to provide a sensor 18 provided on the side surface of the side wall unit 3 and a lamp wire 19 to provide an indicator light 6
, And an automatic lock device 21 for locking the door 5 by a lock control line 20 and a start control line 22 to a start circuit (not shown). The power cord 23
Is for supplying power to the control device 16.

Here, the sensor 18 is for sensing the presence of the user in the toilet booth, and a reflection type sensor using infrared rays or ultrasonic waves is usually suitable. Also, the indicator light 6
Is for externally displaying the status of cleaning, using, etc.,
The displayed contents may be confirmed from the inside of the booth.

Next, the operation of the control device 16 will be described.

When the activation signal is given to the activation control line 22, the presence of the user is determined by the output of the sensor 18, and if there is no user as a result of the determination, a signal for lighting the indicator lamp 6 is output to the lamp line 19 and , Outputs a signal for locking the automatic lock device 21 to the lock control line 20.

Next, a signal for opening the solenoid valve 14 is output to the solenoid valve control line 15.

Therefore, the indicator lamp 6 of the toilet booth 1 is turned on to indicate that cleaning or use is in progress, the door 5 is locked, and then the solenoid valve 14 is opened. Water is supplied to 12 and water is discharged.

After discharging water for a certain period of time, the control device 16 closes the solenoid valve 14, unlocks the automatic lock device 21, and the indicator lamp 6
Each control line outputs a signal to turn off the light.

A timer circuit (not shown) may be provided inside the control device 16 to discharge water every set time (for example, 12:00 in the middle of the night).

The control device 16 that performs the above operation can be configured by a relatively simple electronic circuit.

FIG. 3 is a plan view showing a washing state in which water is discharged from the shower nozzle, FIG. 4 is a sectional view of the same side, and dotted lines in FIGS. 3 and 4 show water flow from the shower nozzle 12.

A plurality of shower nozzles 12 provided on the upper side wall of the side wall unit 3 discharge a radial water flow to a wall surface opposite to the wall surface on which the nozzles are mounted, and wash the side wall surface with running water flowing down the side wall surface.

The discharged water is discharged through a drainage port 11 provided in the floor pan 2 and a toilet bowl 7 to a drainage pipe 10 connected to these.

Next, another embodiment of the present invention will be described.

FIG. 5 shows a wall surface cleaning nozzle on the upper side wall of the side wall unit 3.
It is a partial perspective view of the embodiment provided with 24, and the dotted line in the figure shows running water in the cleaning state.

Here, the structure of the wall surface cleaning nozzle will be described with reference to FIGS. 6 to 8.

The wall surface cleaning nozzle 24 has a base portion 25 for attaching to the side wall surface of the side wall unit 3, and a nozzle portion 26 formed at the tip of the base portion and having a diameter larger than that of the base portion 25. A notch 27 that is open in the lower direction and the front-rear direction is provided. Further, the cutout portion 27 communicates with a flushing water passage 28 penetrating the base portion 25 so that the flowing water can be jetted downward to the side surface of the side wall unit.

Therefore, in the washing state, as shown by the dotted line in FIG. 5, running water for washing flows radially downward along the side wall surface to which the wall surface washing nozzle is attached to wash the side wall surface.

(Effect of the Invention) As described above, according to the present invention, since the nozzle for ejecting the cleaning water is arranged on the side wall surface of the toilet booth, the dirt on the side wall surface is cleaned by running water, so that no human labor is required. Easy to clean.
