Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a urinal, and more particularly to a device for suppressing the generation of odor in a urinal installed in a toilet for business use used by a relatively large number of people such as restaurants.

[0002]

[Prior art]

 As this type of device, a sensor that outputs a detection signal by detecting that a person stands in front of the urinal and that person has left, and a supply that supplies wash water to the toilet based on the detection signal of the sensor What consists of means is known.

[0003]

[Problems to be solved by the device]

 With the above device, urine released from a person standing in front of the urinal and remaining in the urinal is washed with wash water after urinating, so that urine stays in the urinal is minimized. However, it is unavoidable that an odor is generated during urination, which is insufficient as a measure to suppress the generation of odor.

An object of the present invention is to provide a device for suppressing odor generation in a urinal, which can suppress the generation of odor from a urinal to the extent that a person does not feel it.

[0005]

[Means for Solving the Problems]

 The device for suppressing odor generation of urinals according to the present invention detects a person standing in front of the urinal and outputs a detection signal, an ice maker capable of storing a required amount of ice, and a sensor detection sensor. It comprises a supply means for supplying the ice stored in the ice maker to the urinal based on the signal.

[0006]

[Action]

 The device for suppressing odor generation of urinals according to the present invention includes a sensor that detects a person standing in front of the urinal and outputs a detection signal, an ice maker that can store a required amount of ice, and a sensor. Since there is a supply means for supplying the ice stored in the ice maker to the urinal based on the detection signal, when a person stands in front of the urinal, the sensor detects this and based on the detection signal. Ice is supplied from the ice maker to the urinal, and the ice cools the urine released to the urinal, and suppresses the evaporation of odorous components contained in the urine.

【Example】

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

The urinal has a box-shaped toilet body 11 whose height is almost the same as the height of the person M. The front wall of the toilet body 11 is composed of an upper plate 12 and a lower plate 13. The height of the upper plate 12 and the lower plate 13 is formed to be slightly higher than half the height of the front wall. When viewed from the front, the upper plate 12 is arranged in front of the lower plate 13 so that the lower edge of the upper plate 12 and the lower edge of the lower plate 13 overlap with each other with a space in the front-rear direction. A urinary gutter 14 having an inverted trapezoidal cross section is provided along the lower edge of the lower plate 13. Lattice-shaped ice receiving plates 15 are provided on both front and rear edges of the urine gutter 14. An inclined urine return plate 16 is provided at the front edge of the urine gutter 14 so as to rise obliquely forward and upward. A plurality of urination tables 17 are provided in front of the urine gutter 14.

A plurality of human detection sensors 21 are attached so as to correspond to the urination table 17 slightly above the middle of the height of the upper plate 12. A wash water supply pipe 22 is attached to the upper edge of the lower plate 13 along the same. A plurality of injection nozzles 23 are provided at appropriate positions in the wash water supply pipe 22. Immediately below the wash water supply pipe 22 of the lower plate 13, a plurality of ice supply ports 24 are provided so as to correspond to the urination table 17.

An ice maker 25 is installed in the toilet body 11. The ice maker 25 is of a type capable of making ice and storing the produced ice by a required amount. An ice outlet 26 located at a higher level than the ice supply port 24 is provided on the front surface of the ice maker 25. The ice outlet 26 and the plurality of ice supply ports 24 are connected by a branch duct 27. In the branch duct 27, a movable distribution damper (not shown) is installed.

When a person M stands on one of the urination tables 17, a sensor 21 corresponding to the urination table 17 detects this and branches to only the supply port 24 corresponding to the urination table 17 based on the detection signal. The distribution damper is controlled so that the duct 27 is connected. Then, the ice I is immediately discharged from the ice outlet 26. The released ice I is guided to the supply port 24 by the duct 27, and is thrown into the urine gutter 14 from the supply port 24. The input ice I is received by the ice receiving plate 15. The amount of ice I to be thrown in at one time may be, for example, about 3 to 4 ice cubes of 24 mm square. When a person standing on the urination table 17 urinates, the urine is hung on the ice I on the backing plate 15. The temperature of the released urine is about 40 ° C., which is almost equal to the body temperature, but the urine is cooled rapidly by being hung on the ice I, so that the generation of odor is suppressed to the minimum. If there is no ice, the released urine is kept at that temperature for some time, and the generation of odor is unavoidable. The cooled urine flows through the urine gutter 14 and is discharged from a discharge port (not shown).

When the person M, who has finished urinating, descends from the urination table 17, the sensor 21 detects this and the nozzle 23 injects washing water based on the detection signal. The flush water cleans away the urine remaining in the urine gutter 14 while flowing through the urine gutter 14 and is discharged from the outlet.

In the above embodiment, the ice is supplied only from the supply port corresponding to the operated sensor, but when any one of the sensors is operated, the ice is simultaneously supplied from all the supply ports. It may be supplied.

Further, in the above-described embodiment, the control of the ice supply and the injection of the washing water is performed based on the detection signal of one sensor, but the two sensors are used to separately control the two. May be.

[0015]

[Effect of device]

 According to this invention, when a person stands in front of the urinal, the sensor detects it, and the ice maker supplies ice to the urinal based on the detection signal, and the ice is discharged to the urinal. Since the urine is cooled and the evaporation of the odorous components contained in the urine is suppressed, the generation of the odor from the urinal can be suppressed to a minimum.
