Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a deodorizing device for a flush toilet.

"Conventional technology" Conventionally, in collective housing such as condominiums and apartments,
Due to land space and building structure, it is not possible to arrange the floor plan as desired. In particular, it is difficult to locate toilets that require ventilation where windows can be provided.

Even with ventilation fans, defecating in a closed room produces a foul odor, and even after defecating, the odor sticks to one's clothes, making it difficult to enter the building for a while. Also, I would be extremely reluctant to use it immediately after someone else has used it. In addition, in conventional seated toilets, the water pool surface is widened in consideration of the release of odors, but this causes other problems such as splashing.

In particular, a Japanese-style toilet that temporarily collects waste in a toilet bowl and flushes it away with the force of water produces a particularly bad odor.

Also, deodorizing with air fresheners is not perfect and is only temporary.

``Problems to be Solved by the Invention'' The present invention has been made in view of the above points, and is intended to eliminate unpleasant odors during defecation, even when defecating in a closed toilet without windows or ventilation fans. The purpose of the present invention is to provide a deodorizing fitting for a flush toilet that does not emit odor into the atmosphere and also prevents odor from remaining in the toilet after using the toilet.

"Means for Solving the Problems" The gist of the present invention is to provide an odor evacuation device equipped with an intake hole and an exhaust hole in the lid of a water tank, and to provide an odor discharge device at the end of the overflow pipe of the water tank. One end of the hollow tube is fitted over the provided overflow port so that it can be submerged in water, and the other end is connected to the intake hole to form an odor flow path, and when a switch is actuated, the odor exhaust device is activated. is activated, and this operation sucks in the odor of filth from a cleaning hole drilled in the toilet body, and discharges it to the outside of the toilet from an exhaust pipe connected to the odor evacuation device via a reverse valve. The feature lies in the odor evacuation device for flush toilets.

Hereinafter, embodiments of the present invention will be described based on the drawings.
The figure is an explanatory diagram of the operation of the odor evacuation device of the present invention, and FIG. 2 is an explanatory diagram of the operation with a water tank partially omitted. In the figure, l is the toilet bowl body, and 2 is a toilet bowl provided with a water reservoir 3 for alleviating the adhesion and odor of filth that is being drained. The toilet bowl 2 forms a cleaning hole 4 serving as a flow path for flushing water and a passage 5 for discharging waste into the sewer, and holds a toilet seat 6. 7 is a water storage tank with 14 wash water inside, and an overflow pipe 9 with a drain port 8 bored in the bottom wall is installed vertically.
An overflow port 10 opened at its upper end is provided so as to protrude from the water surface 11. The float 12 is in close contact with a float valve 13, and is a switch for causing the wash water in the water tank 7 to flow out by operating a lever 14. 15 is water tank 7
This is an odor evacuation device that has an intake hole 17 provided in a chamber 16 above the water surface inside the tank, an exhaust hole 18 exposed to the outside, and an exhaust fan 20 that is driven by a motor 19. It is molded integrally with the body 21. 2
Reference numeral 2 is a hollow pipe with openings at both ends having different diameters, and the large-diameter opening 23 is directed downward at the upper end of the overflow pipe 9 which is vertically installed on the bottom wall of the water tank 7. The opening 24, which has a small diameter, is connected to the intake hole 17 by a connecting pipe 25 to form an odor flow path 26.・This is Tachino. The positional relationship between the fire tubs AB in FIG. 2 must be of sufficient height so as not to impede the discharge of overflow land water. Furthermore, the motor 19 is a timer control 2
7, and this communication is communicated to the switch 28 and the indicator light 29, respectively. Further, a check valve 3° and an exhaust pipe 31 are connected to an exhaust hole 18 formed in the odor exhaust device 15 and connected to a sewer pipe 32.

``Function'' Now, to explain the function of the present invention having the above-mentioned configuration, when the switch 28 is activated, the indicator light 29 notifying the operation lights up, and the timer control 27 is contacted, and the communication is sent to the water tank 7. The motor 19 of the odor evacuation device 15, which is integrally formed with the lid 2I, is connected, and the motor 19 operates the exhaust fan 20.

In addition, the odor of waste discharged into the toilet bowl 2 of the toilet main body I,
As shown by the fire source in the figure, it rises in the W direction and dissipates into the atmosphere. Therefore, the structure is such that this filth odor is sucked out by the above-described operation. That is, the large-diameter opening 23 of the hollow pipe 22 fitted over the upper end of the overflow pipe 9 is submerged in water and is therefore isolated from the chamber 16 above the water surface. therefore,
A cleaning hole 4 drilled in the toilet bowl 2, an overflow pipe 9, and the hollow pipe 2
2 communicate with each other to form an odor flow path 26. Further, the small-diameter opening 24 of the hollow tube 22 is connected to the intake hole 17 formed in the odor exhaust device 15 through a connecting tube 25,
The operation of the exhaust fan 20 causes the odor of filth in the toilet bowl 2 to be sucked through the odor passage 26 formed as described above. In addition, since the opening 23 of the hollow tube 22 is opened when the cleaning water flows out, there is no obstruction due to the suction action of the odor evacuation device 15, and there is a sufficient distance between A and B indicated by the fire source. Even in the event of an overflow, the overflowing water can be easily drained without any difficulty. Further, an odor evacuation device 1 is formed integrally with a lid body 21 that covers the water storage tank 7.
The exhaust hole 18 drilled in 5 is connected to an exhaust pipe 31 for exhausting the odors of filth sucked into the exhaust fan 20, which is activated by operating the switch 28. A check valve 30 is linked to prevent backflow. Therefore, even if the exhaust fan 20 stops, the odor that has been exhausted will not return to the intake system due to the check valve 30. The exhaust pipe 31 thus connected is connected to the sewage pipe 32 of the toilet main body 1 to discharge odor. The exhaust pipe 31 may be arranged so as to discharge to a place other than the above. For example, although not shown, it may be connected to an exhaust duct by passing through a wall, or a partition wall may be provided at the window to connect it to the outside of the window. However, in this case, it is preferable to install a filter with a deodorizing function. In addition to the method using a forced exhaust fan, there are various methods of implementing the odor exhaust device, such as suction using a negative pressure pump, but in this example, the former method using a forced exhaust fan is used. However, the latter negative pressure pump may also be used.

In short, the deodorizing device of the present invention is designed to prevent the odor of filth in the toilet bowl 2 of the toilet main body 1 from rising and dissipating in the direction of the fire pit W.
The lower opening 23 of the hollow tube 22 fitted over the end of the overflow pipe 9 is immersed in the water through the overflow pipe 9 which is vertically installed in the water tank 7 as an inlet, so that atmospheric air cannot be inhaled. The hollow pipe 22 is connected to the air intake hole 17 of the odor evacuation device 15 using the connecting pipe 25.
The filth odor sucked out by this is connected to the exhaust hole 1 on the discharge side of the male air exhaust device 15.
8 through a check valve 30 for preventing the backflow of waste odor,
The air is discharged from the exhaust pipe 31 to the outside of the toilet.

In this embodiment, a push-button timer switch is used, but other switches may be used, such as a switch provided with a seat sensor (not shown) on the toilet seat 6 or a foot-operated switch. Furthermore, it goes without saying that the odor evacuation device of the present invention can be installed and used in Japanese-style toilet bowls other than those in this embodiment.

``Effects of the Invention'' Since the present invention has the above-described structure and operation, the odor of waste discharged into the toilet bowl of the toilet main body is forcibly discharged outside the toilet room without drifting into the atmosphere. There is no odor at all during or after using the toilet. Therefore, it is hygienic and comfortable to use, and is especially suitable for unit-type bathroom toilets that are often used in studio apartments. Furthermore, the invention is simple and easy to install not only in newly constructed toilets but also in existing toilets, and its effects are practical and meaningful.
