AI Technical Summary

Technical Problem

Conventional toilets face sanitation issues during emergencies due to water supply disruptions, leading to unpleasant odors and increased water consumption without use, resulting in unsanitary conditions and high water bills.

Method used

An ice maker is integrated into the toilet, producing ice that falls onto the urinal seat, where body heat melts it, draining it through the drain, maintaining sanitation and conserving water by eliminating the need for continuous water flow.

Benefits of technology

The system maintains public sanitation and reduces water usage by using body heat to melt ice, addressing sanitation issues during emergencies and reducing water costs.

Abstract

We provide toilets that eliminate unpleasant odors and conserve water. [Solution] Toilet T is equipped with a ceramic toilet bowl, and an ice maker 300 requiring power is installed above the toilet bowl. A water channel 200 and a pump 100 are connected to the ice maker 300. A water tank 101 integrated with the pump 100 stores tap water containing fragrance. The fragrance-infused tap water is sent to the ice maker 300 via the water channel 200 by the pump 100. In the ice maker 300, the fragrance-infused tap water freezes and falls by its own weight into the urinal 500 from three locations on the pipe P.

[0005]

[0001] This invention consists of an ice maker 300, a water channel 200, a pump 100, a water supply tank 101, a socket C, a urinal 500, and a timer Time in a toilet T, and has a structure in which three pipes P are attached to the ice maker 300.

Background Art

[0002] Conventional toilets have an odor elimination function that automatically flows water at a certain timing to eliminate the smell. In this case, in an emergency such as a natural disaster, not only does water supply stop and water does not flow, but also unpleasant odors often occur, causing unsanitary problems to public health. <​​​​​​​​​​​​​​​​​​​​​​

[0007] In this invention, ice 800 that has fallen from the pipe P of the ice maker 300 is stored on the lower seat surface 400 of the urinal 500. When a person urinates, the body temperature of the urine melts the ice, which is then drained into the sewer through the drain 600, thus maintaining public sanitation at all times. Furthermore, conventional toilets required unnecessary water at certain times to maintain public sanitation even when no one was present, resulting in high water bills. This invention provides a water-saving toilet that maintains public sanitation at all times and does not incur running costs for water. [Brief explanation of the drawing]

[Figure 4] Perspective view of the cooling system [Figure 5] Downward perspective view of the cooling system [Modes for carrying out the invention]

[0009] Regarding Figure 1, toilet T has a ceramic urinal 500 with a drain 600, and an ice maker 300 is installed on top of it. The ice maker 300 is connected to a pump 100 by a water channel 200, and the pump 100 is connected to a water tank 101. The pump 100 is responsible for sending a fragrant liquid contained in the water tank to the ice maker 300 through the water channel 200. Three pipes P are attached to the ice maker 300. An electrical outlet C is also attached to the ice maker 300.

[0010] To explain the ice maker 300 in more detail, it has a timer that can be set for short time, medium time, and long time. By setting the timer, it is possible to set the amount of ice 800 frozen in the ice maker 300 that will be placed on the lower seat surface 400 of the ceramic urinal 500.

[0011] In Figure 2, the toilet T is made of ceramic, and three pipe penetration holes 301 are provided at the top of the toilet T. At the bottom of the toilet T, there is an exhaust vent 600 for draining urine and other waste into the sewer system.

[0012] Regarding Figure 3, toilet T has an ice maker 300 mounted on top of a ceramic urinal 500, which requires a drain 600. The ice maker 300 is connected to a pump 100 by a water channel 200, and the pump 100 is connected to a water tank 101. The pump 100 is responsible for sending a fragrance-containing liquid, which is stored in the water tank, to the ice maker 300 through the water channel 200. Three pipes P are attached to the ice maker 300. An electrical outlet C is also attached to the ice maker 300. The difference from Figure 1 is that the ice 800 produced by the ice maker 300 is stored by its own weight on the lower seat surface 400 of the ceramic urinal 500. The ice stored on the lower seat surface 400 contains a fragrance, and even when no one is urinating, it melts naturally, maintaining public health at all times. Furthermore, when a person urinates, the body temperature of the urine melts the ice containing the fragrance, thus conserving water and maintaining public health.

[0013] Figure 4 is a perspective view of the assembled components of the cooling device CD. The cooling device CD stores a liquid containing fragrance in the water tank 101, which is drawn up by the pump 100 and transported through the water channel 200 to the ice maker 300. The top of the ice maker 300 is equipped with a Time timer, which can be set in combination with short-time, medium-time, and long-time settings, allowing for the setting of the time it takes to make ice inside the ice maker 300. The cooling device CD is powered by outlet C. The ice made inside the ice maker 300 falls down from the opening of pipe P by its own gravity, forming ice 800.

[0014] Figure 5 is almost identical to Figure 4, but the difference is that Figure 5 is a diagram drawn from below. The ice input outlet Out, which is not shown in Figure 4, is shown in Figure 5. In this way, the ice 800 produced in the ice maker 300 is drawn in by gravity from three locations in pipe P and the ice input outlet Out.

[0015] Thus, the above-described embodiments are merely illustrative in all respects and should not be construed restrictively. Further, forms and modifications belonging to the equivalent scope of the utility model registration claims are all within the scope of the present invention.

Industrial Applicability

[0016] The present invention is a simple toilet with high urgency during disasters, a toilet for water conservation purposes, and a toilet for maintaining public hygiene, and has industrial applicability in order to provide a highly versatile toilet.
