Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention can automatically supply chemical liquids such as cleaning liquids and deodorant liquids to a toilet bowl provided in a toilet to detect a user of the toilet bowl. The present invention relates to a mechanism for automatically supplying a medicine to a toilet bowl, which can spray the medicine and keep the toilet bowl clean at all times.

[Conventional technology]

The toilet provided in the toilet is for daily use.
Unless it is cleaned regularly, human waste is likely to adhere to the toilet bowl and become dirty.

In a flush toilet set up in a home or the like, water is flushed into the toilet bowl each time it is used, so it is relatively hard to get dirty. In addition, special toilet bowls, such as those used in airplanes and Shinkansen cabins, have a function of mixing chemicals with the water flowing in the toilet bowl and discharging the water containing the chemicals each time it is used to remove dirt. There is also.

In such a flush toilet located in a place where clean water can be supplied, it is easy to automatically clean the toilet bowl because water and chemicals can be flushed after each use.

However, a non-washed toilet and a mobile toilet where water cannot be used have to be cleaned regularly, which is troublesome.

In recent years, the use of temporary toilets that can be temporarily installed in the suburbs or open spaces has become popular, and in such non-washable mobile toilets that cannot use water, regular toilets are used. Cleaning was essential.

In this mobile toilet, cleaning is usually performed manually. Therefore, it has been devised to prevent dirt from adhering to the toilet bowl as much as possible. As an example, such a mobile type temporary toilet is equipped with a chemical supply device so that a cleaning agent can be sprayed on the toilet bowl, and the chemicals are attached to the toilet bowl to remove dirt and to clean the toilet bowl. Also exists. In this case, in order to operate the medicine feeder, the user of the toilet has to operate the lever, cock, etc. each time it is used.

However, it is troublesome for the user of the toilet to operate the chemical supply device every day or each time it is used, and it is easy for the user to forget this operation, even if the chemical supply device is installed. The actual effect has not occurred.

Therefore, in the movable temporary toilet, the toilet bowl is apt to be left dirty and left to be cleaned, and the cleaning operation after use is inevitably required, which requires an extremely troublesome operation for the worker.

[Problems to be Solved by the Invention]

In conventional temporary toilets and non-flush toilets, it has been necessary to clean the toilets on a daily basis, but it is often easy to forget because there are many people who are careless and lazy. In addition, even if the chemical supply device is installed, it is not always possible to operate the chemical supply device, and as a result, the toilet bowl is left dirty.

In order to solve this point, there has been developed a device that sprays a cleaning liquid on a toilet at regular time intervals using a timer. However, when operated with this timer, regardless of the number of times the toilet is actually used, it is possible to eject the cleaning liquid,
There is no correlation with the dirt on the toilet bowl, and the cleaning liquid is wasted. On the other hand, when there are many users of the toilet bowl, the toilet bowl becomes dirty and cannot be cleaned with only the cleaning liquid. In addition, even if holidays continue, or if a temporary toilet is installed in a remote mountain area and the number of times the user uses it is small, if the timer is activated and the cleaning liquid is spouted at regular intervals, it is wasteful. It was not suitable for actual use because of its various actions and the release of cleaning liquid.

Therefore, it has been desired to develop a mechanism in which the cleaning liquid is sprayed in conformity with the actual usage state of the toilet bowl, and the toilet bowl is constantly cleaned.

[Means to solve the problem]

In order to solve the above-mentioned drawbacks, the present invention is a toilet provided in a toilet room, a liquid tank for storing a chemical liquid, a suction supply unit for sucking the chemical liquid in the liquid tank, and a pressure supply from the suction supply unit. Spraying means for spraying the chemical liquid inside the toilet bowl, detecting means provided in the toilet room for detecting the presence of a person, and control means for activating the suction supply means for a predetermined time by the signal output from the detecting means. And a mechanism for automatically supplying chemicals to a toilet, which is configured by the control means, the detection means, and a solar power generation means for generating electric power for driving the supply means.

[Action]

In the present invention, when the user enters the toilet room, the detection means detects the presence of the user, and the toilet bowl can be cleaned by always spraying a predetermined amount of cleaning liquid on the toilet bowl for one use. I can. For this reason, when the number of users is large, the cleaning liquid is sprayed each time, so that it is difficult for the toilet bowl to become dirty even if it is used many times. In mountainous remote areas,
The cleaning liquid is not sprayed when the number of uses is small or when there are no users when holidays continue.
It is possible to avoid wasteful use of the cleaning liquid.

〔Example〕

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

FIG. 1 illustrates a specific example of the present invention applied to a temporary toilet which can be moved.

The mobile toilet 1 is mounted on a truck or the like and installed on a temporary ground such as a vacant lot or a construction site for use, and the mobile toilet 1 itself functions as a toilet.

In the lower part of the mobile toilet 1, a toilet bowl 5 for storing human waste is provided, and the toilet bowl 5 is in the shape of a tank, and a toilet bowl 6 is installed above the toilet bowl 5. In addition, a urinal 7 is fixed to the inner side wall of the mobile toilet 1, and the urinal 7 and the urinal 5 are connected by a drain pipe 8 and discharged from the urinal 6 and the urinal 7. The collected excrement will be stored in the toilet tank 5.

A liquid tank 9 containing a chemical liquid such as a cleaning liquid and a deodorant liquid is installed inside the mobile toilet 1, and a supply pipe 10 is connected to the liquid tank 9. Further, a detector 11 as a detection means for detecting that a user has entered the mobile toilet 1 is fixed to the upper part of the inner wall of the mobile toilet 1. Further, on the roof of the mobile toilet 1, a solar cell unit 12 is fixed as a solar power generation unit that receives an electromagnetic ray to generate an electromotive force.

Next, FIG. 2 explains the control system in this embodiment in detail.

A pump 21 as a suction supply means is interposed between the supply pipes 10, and the pump 21 and the urinal 7 are provided.
An accumulator 22 is provided in the supply pipe 10 between and. A chemical liquid 23 is stored in the liquid tank 9.

This pump 21 has a cylinder 25 with one end closed,
It is composed of a piston 26 that slides in the cylinder 25, and a spring 27 for constantly pushing the piston 26 outward is housed in the cylinder 25. And
A valve chamber 28 is connected to the lower portion of the cylinder 25, and a valve ball 29 is housed in the valve chamber 28 so that the chemical liquid 23 can be moved only in one direction by the valve ball 29. It has become. A valve chamber 30 is connected to the upper part of the cylinder 25, and a valve ball 31 for moving the chemical liquid 25 in one direction is stored in the valve chamber 30.

The position facing the side surface of the piston 26 is the rod.
32 is movably provided to the left and right, and this rod 32 is in contact with the outer circumference of an eccentrically supported cam 33.
Is driven by a motor 34.

Next, the electromotive force from the solar cell unit 12 is supplied to a secondary battery 40 that can be charged and discharged many times, and the power of the secondary battery 40 is an electric power including a control circuit 44 as a control unit. Supplied to the circuit.

First, a light emitter 41 that emits infrared rays is provided in the detector 11.
There is a light receiver 42 for receiving infrared rays, and the light emitter 41 and the light receiver 42 are connected to a detection circuit 43. This detection circuit 43
Is connected to the control circuit 44, and the output of the control circuit 44 is connected to the timer circuit 45.

The timer circuit 45 can supply driving power for a fixed time, and the output of the timer circuit 45 is connected to the motor 34.

 Next, the operation of this embodiment will be described.

A user who intends to defecate using the mobile toilet 1 first opens the door 4 and opens the doorway 2. Then
The doorway 2 allows access to the inside of the mobile toilet 1. Then, by closing the door 4, the door 4 closes the doorway 2 around the hinge 3 and closes the inside of the moving toilet 1. The purpose can be achieved by using the urinal 7 for defecation.

At this time, infrared rays are constantly emitted from the light emitting device 41 from the detector 11, and when the user stands inside the moving toilet 1, the infrared light emitted from the light emitting device 41 is reflected and the reflected infrared light is received. It is sent back to the vessel 42. Therefore, the light receiver 42 informs the detection circuit 43 that there is the reflected light, and the detection circuit 43 determines that there is a defecation user in the mobile toilet 1. Then, the detection circuit 43 transmits the signal to the control circuit 44, and the control circuit 44 simultaneously outputs the signal to the timer circuit 45. Therefore, the timer circuit 45 supplies electric power so as to drive the motor 34 for a fixed time (between several seconds and several tens of seconds).

Electric power for operating the control circuit 44, the timer circuit 45, the motor 34, etc. is supplied from the secondary battery 40, and the secondary battery 40 is supplied from the solar cell unit 12 mounted on the roof of the temporary toilet 1. The electric power is constantly charged with the stored electric power, and the motor 34 is driven by using the charged electric power.

When the motor 34 is driven, the cam 33 rotates, causing the rod 32 contacting the outer periphery of the cam 33 to reciprocate along the length direction thereof. The movement of the rod 32 is transmitted to the piston 26 at the same time, causing the piston 26 to slide in the cylinder 25. Then, the piston 26 is moved against the elasticity of the spring 27 so as to be pushed into the cylinder 25. Therefore, the chemical liquid 23 in the cylinder 25 is
Is pushed up to flow in the direction of the supply pipe 10. A part of the pressure of the chemical liquid 23 pushed out by the piston 26 is retained in the accumulator 22, and the accumulator 22 maintains a constant pressure. Then, the chemical liquid 23 is ejected from a nozzle 24 as a spraying device at the tip of the supply pipe 10 and is atomized toward the inner peripheral wall of the urinal 7. In this way, the chemical liquid 23 is attached to the inner peripheral wall of the urinal 7, and the dirt on the inner peripheral wall of the urinal 7 is removed.
Since a part of the chemical liquid 23 stored in the accumulator 22 is kept at a constant pressure by the pressure of the rubber film or the like in the accumulator 22, the force causes the chemical liquid 23 to be ejected from the nozzle 24. It is possible to continue the action for a certain time.

When the rod 32 is pulled back by the cam 33, the piston 26 is pushed outward by the force of the spring 27 and moves. Then, the chemical liquid 23 is sucked into the cylinder 25 by the volume corresponding to the movement of the piston 26, passes through the valve ball 29, and is sucked into the cylinder 25.

The chemical liquid 23 sucked up in the cylinder 25 is a ball 29.
Therefore, it will be retained inside the cylinder 25 without backflow. By repeating this operation, the nozzle 24
From then, the chemical liquid 23 is sequentially sprayed.

Next, FIG. 3 shows another embodiment of the present invention.
In this embodiment, the chemical liquid is sprayed into the toilet bowl 6. In this embodiment, the same parts as those in FIGS. 1 and 2 are designated by the same reference numerals and the description thereof is omitted.

In this embodiment, the supply pipe 10 is connected to a Western-style toilet seat type toilet bowl 6, and the nozzle 24 at the tip of the supply pipe 10 is directed toward the inner wall of the toilet bowl 6 in an oblique direction. Has been. A pump unit 50 is provided in the middle of the supply pipe 10. Further, a detector 11 is fixed to the inner wall of the mobile toilet 1 at a lower position thereof.

In this embodiment, since the user enters the inside of the mobile toilet 1 and sits on the toilet 6 as described above, the infrared rays from the detector 11 are reflected, so that it can be determined that the person is using it. You can Then, in the same manner as described above, the motor 34 is operated to suck up the chemical liquid 23 from the liquid tank 9 and spray it from the nozzle 24 onto the inner circumference of the toilet bowl 6. The chemical liquid 23 sprayed from the nozzle 24 is jetted obliquely so as to adhere to the entire inner peripheral wall of the toilet bowl 6, so that the chemical liquid 23 is applied to the entire inner peripheral wall of the toilet bowl 6. . When the chemical liquid 23 is sprayed, the excrement does not adhere to the surface of the inner peripheral wall of the toilet bowl 6, and the excrement flows down toward the toilet bowl 5.

This operation causes the chemical liquid 23 to be ejected to the inner circumference of the toilet bowl 6 each time the user enters the mobile toilet 1, so that the inner wall of the toilet bowl 6 is always kept clean.

〔The invention's effect〕

Since the present invention is configured as described above, when the user who uses the toilet enters the toilet room, the presence of the user can be detected, and the chemical liquid can be sprayed on the inner wall of the toilet each time, and the toilet bowl is always clean. Can be kept at When spraying this chemical liquid on the toilet bowl, the operation is performed after detecting that the user has entered the toilet room, so that the operation is consistent with the actual state of the user, and the waste of the chemical liquid is avoided. No extra power consumption. Moreover, since the chemical liquid is released each time according to the frequency of the user, the toilet bowl can be kept clean at all times.
