Description

Toilet with automatic disinfection system

The invention relates to a sitting toilet, in particular to a sitting toilet with an automatic disinfection system.

The toilet is the most common sanitary ware. Due to the use environment, there are a large number of bacteria and viruses in the toilet body, seat and cover of the toilet. In order to prevent the spread of bacteria and viruses to users, it is generally recommended to perform a disinfection operation after use. In the past, the toilet required manual disinfection by users, such as spraying disinfectant or cleaning with disinfection paper towels. However, out of fear of dirt, users are reluctant to perform manual disinfection. For this reason, self-sterilizing toilets have appeared. For example, the prior application in the United States, Announcement No. US7028346B2, provides a self-sterilizing toilet, which sprays disinfectant to the seat plate through a nozzle set in the toilet for disinfection. , The disinfectant is usually a chemical cleaning agent, but the disinfectant is not environmentally friendly and will pollute the drainage system. In addition, UV lamps are also widely used in toilet cleaning due to their convenient use and low cost. For example, another U.S. prior application, Bulletin No. US9861239B1, proposed a technical solution to use UV lamps to disinfect the seat board, but UV Lights cannot kill all bacteria or viruses. There is also a disinfection system that can clean and dry the seat board, such as the previous application in the United States, the announcement number US2008/0301867A1, but the structure is relatively complicated and inconvenient to use, and the UV lamp will affect the overall appearance, the use of LED UV The lamp is set on the bottom surface of the seat board, so only partial sterilization or disinfection can be achieved, and the seat board cannot be fully sterilized or disinfected. In addition, the Chinese utility model patent, publication number CN201806634U, discloses a device that uses ozone to disinfect the toilet. On the one hand, the entire toilet needs to be disinfected, so the amount of ozone released is relatively large; on the other hand, after disinfection After using a large amount of ozone and no specific plan is proposed to quickly decompose or discharge the ozone, the ozone is likely to leak out of the toilet along the gap in the toilet, which will increase the health risks of the user.

In view of the above-mentioned shortcomings of the prior art, the present invention provides a toilet with an automatic disinfection system, which has a simple overall structure and is very convenient to use.

A toilet with an automatic disinfection system includes a toilet body and a flushing device. The flushing outlet of the flushing device is connected to the toilet body. The upper opening of the toilet body is covered with a seat plate, and the seat plate is covered with a cover plate. , The cover plate covers the upper opening of the toilet body, and the bottom surface of the cover plate is provided with an air hole for releasing disinfection gas, and the air hole is connected to the disinfection gas generator; a control system is also provided, which is respectively connected to the flushing Device and disinfection gas generator. When the cover plate covers the upper opening of the toilet body, the control system controls the disinfection gas generating device to release the disinfection gas, and the disinfection gas is released into the seat plate and the toilet body through the air hole for disinfection; After completion, the control system controls the flushing device to flush the toilet main body, and the disinfection gas in the toilet main body is discharged from the toilet main body along with the water flow from the drainage port.

Wherein, the disinfection gas is released into the narrow space between the cover plate and the seat plate through the air holes, and the concentration of the disinfection gas is 100 ppm to 10,000 ppm, and only the seat plate is disinfected.

Wherein, the disinfection gas is ozone.

Wherein, the seat board is installed to the upper opening of the toilet body through an automatic rotation mechanism I, and the automatic rotation mechanism I is connected to the control system.

Wherein, the cover plate is installed to the upper opening of the toilet body through an automatic rotation mechanism II, and the automatic rotation mechanism II is connected to the control system.

Among them, there are switches and/or sensors for detecting whether the cover plate is closed. When the cover plate is closed, the control system can control the release of disinfection gas; when the cover plate is opened, the control system cannot or stop releasing the disinfection gas.

When the toilet is used up and the cover is covered, the sterilizing gas is released from the pores of the upper cover and filled in the seat and (or) the main body of the toilet, disinfecting the seat and (or) the main body of the toilet Sterilize, and after closing the cover, it can effectively prevent the leakage of disinfection gas, so as not to affect the health of users; after disinfection is completed, the flushing device will flush the remaining disinfection gas from the buckle with the water flow, which can effectively remove Disinfect the gas to ensure safer use.

Example

The present utility model will be further described below in conjunction with the description of the drawings and specific implementations.

1 to 4, a toilet with an automatic disinfection system includes a toilet body 1 and a washing device 2. The washing outlet of the washing device 2 is connected to the toilet body 1, and is open on the toilet body 1. The mouth is covered with a seat plate 3, the seat plate 3 is covered with a cover plate 4, the cover plate 4 covers the upper opening of the toilet body 1, and the bottom surface of the cover plate 4 is provided with an air hole 5 for releasing disinfection gas , The air hole 5 is connected to the disinfection gas generator; there is also a control system, which is respectively connected to the flushing device 2 and the disinfection gas generator. When the cover plate 4 covers the upper opening of the toilet body 1, the control system controls the disinfection The gas generating device releases disinfection gas. The disinfection gas is released into the seat plate 3 and the toilet body 1 through the air hole 5 for disinfection. The disinfection gas can effectively fill the toilet and each position of the seat plate 3 to ensure that the toilet can be fully used. Disinfection and sterilization of various parts of the plant. Since the disinfection gas is generally toxic, if it leaks out of the toilet, it may cause harm to the human body. After the disinfection is completed, the flushing device 2 will flush the remaining disinfection gas from the buckle and follow the water flow, which can be effective Prevent the leakage of disinfection gas, thereby ensuring safer use.

The disinfecting gas used in the present invention is ozone. Ozone can kill all bacteria and viruses, and can also eliminate odor, which is very suitable for use in toilets. However, if the ozone reaches a certain concentration, it will be dangerous to the human body. According to the research of the National Institute of Occupational Safety and Health, NIOSH, if the ozone concentration reaches 5ppm, it will cause harm to health and even life.

In order to achieve the ideal disinfection effect, the concentration of ozone needs to be at least 100ppm or 0.2mg/L, and the toilet space is between 5-10L. If the entire toilet is disinfected, 1～2mg ozone is needed. The disinfection process is less than 60 seconds. Can kill more than 50% of bacteria. However, if 10ppm ozone is used, it will take a longer time, such as 5 minutes, which can only kill less than 50% of bacteria. However, 10ppm ozone can also effectively deodorize. However, when the concentration exceeds 10,000 ppm, it is dangerous to users due to its strong toxicity.

And if you want to disinfect the seat, you only need to design the space between the cover and the seat within 1L, then only 0.2mg of power is needed to complete the disinfection, and 0.2mg of ozone can be eliminated through the toilet flushing process. In addition, since the seat board 3 is most in contact with the human body when the toilet is in use, the inventor considers that the minimum dose of ozone is used to achieve the purpose of sterilization and disinfection. On the one hand, it can save cost or release time, and on the other hand, the small dose The chance of ozone leakage is smaller and the toxicity is relatively low. Therefore, the preferred solution of the present invention is that ozone is released between the cover plate and the seat plate through the pores, and only a small dose of ozone with a concentration of 100ppm to 10,000ppm is required. It is formed to reach a high concentration in the above-mentioned narrow space, thereby sterilizing and disinfecting the seat board.

Before the ozone is released, the cover plate 4 is lowered to cover the toilet. Then, the ozone generator is turned on to generate ozone, and the high-concentration ozone air is sprayed on the toilet and the seat board 3 by using a blower to disinfect it. At the same time, ozone will also react with volatile organic compounds (VOC) to eliminate odors, which are the source of odors. This operation performs both disinfection and deodorization processes. Common bacteria found in toilets, such as Escherichia coli, Salmonella and Staphylococcus aureus, are very sensitive to ozone and most will be killed. Then, the control system automatically starts the flushing operation, which helps to eliminate the remaining ozone. Finally, the cover plate 4 is ready for the next use.

In order to enable the system to automatically complete the entire disinfection process, the opening and closing of the seat plate 3 and the cover plate 4 are completed by automatic rotation mechanisms I and II, respectively, which are controlled by the control system. In addition to achieving automatic control, it can also ensure that the entire disinfection process is completed in accordance with the established steps, as follows: After using the toilet, the cover 4 is closed by the automatic rotation mechanism II, so that the upper part of the toilet is closed. The opening is closed to prevent the subsequent ozone leakage, and then the disinfection gas generator generates ozone and releases it into the toilet through the air hole 5 of the cover plate 4 to disinfect the toilet and the seat board 3, etc.; with disinfection completed, flushing device 2 Flushing water into the toilet will generate negative pressure in the toilet during the drainage of the toilet, so that the remaining ozone will also follow the water flow and be discharged from the drainage port, further preventing ozone from leaking along the gap of the cover 4.

Finally, referring to Figure 5, in order to further ensure the installation of use and prevent the leakage of disinfection gas caused by accidentally opening the cover during the sterilization and disinfection process, the present invention is provided with a switch and (or) sensor for detecting whether the cover 4 is closed. When the cover 4 is closed, the control system can control the release of disinfection gas; when the cover 4 is opened, the control system cannot or stop releasing the disinfection gas.
