2. Description of Related Art
Toilet is one of the most important equipment in modern life. Among the many kinds of toilets, the most common type is a flush toilet, in which water takes away waste and cleans the surface of the toilet. However, flushing the flush toilet wastes large volumes of water. Although there are many kinds of low-flush toilets for water saving, the effect is limited due to how the flush toilet works. Therefore, a new toilet and a new cleaning method in needed for water conservation.
SUMMARYA toilet is provided, which comprises a container, a cover, and an inflator. The container includes a top opening and a bottom drain, located on the top and the bottom of the container separately. The cover pivotally connects the container, and is used to shield or expose the top opening selectively. When the cover shields the top opening, the inflator supplies air into the container and makes the air pressure inside the container higher than the outside. And therefore, air flows and takes away wastes through the bottom drain to the outside of the toilet due to air pressure differential.
The invention also provides a toilet seat for installing on a toilet. The toilet seat has a cover for selectively shielding or exposing a top opening of the toilet. When the cover shields the top opening, an inflator, which is connected to the cover, supplies air into the toilet and makes the air pressure increase. Because air pressure inside the toilet is higher than the outside, this may drive air flowing and taking away waste through the bottom drain to the outside of the toilet.
On the other hand, the invention also provides a cleaning method for toilet. First, closing a top opening of a toilet. Then, increasing the air pressure inside the toilet and making air take away waste through a drain of the toilet to the outside of the toilet.
In the foregoing, the pressure differential between the inside and the outside of the toilet drives air flowing and therefore brings waste out of the toilet without water. Therefore, using the embodiments of the present invention can clean the toilet and conserve water.
These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description and appended claims.
It is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the invention as claimed.
The invention can be more fully understood by reading the following detailed description of the embodiment, with reference made to the accompanying drawings as follows:
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
In the embodiment, the cover 120 connects to the container 110 with a pivot 122 on an end of the cover 120. The cover 120 can be made by rubber. When a user pushes down the inflator 130 on the cover 120, also presses the cover 120 against the container 110, and thus seals the opening 112.
In addition, in order to seal the opening 112 for preventing air escaping from the opening 112, the toilet 100 has a lock 140 to fix the cover 120 tightly on the container 110. The lock 140 could be a fastener, a latch, a bolt, a pivot, etc. The lock 140 can be divided into two elements, a first lock element 142 and a second lock element 144 located on the cover 120 and the container 110 separately. When the cover 120 shields the opening 112, the first lock element 142 and the second lock element 144 may hold together and therefore locks the cover 120 and the container 110. In the embodiment, the first lock element 142 and the second lock element 144 are a mortise and a tenon. In another embodiment, the first lock element 142 and the second lock element 144 are a group of gear wheels on the pivot 122, which could lock up after the cover 120 shielding the opening 112. The cover 120 remains over the container 110 until the gear wheels unlock.
The inflator 130 is a device that is used to force air into the container 110, for example an air pump, a compressor, a blower, etc.
In order to prevent the surface 116 of the container 110 from staining and adhered by the waste 150, the surface 116 has been spread with material, such as Teflon, porcelain glaze, or nano-scale graze, to form a smooth coating.
Additionally, toilet 100 further has a cleaning device 170 for cleaning the toilet 100 and moistening the surface 116 to prevent the surface 116 from adhering by the waste 150. The cleaning device 170 connects to the cover 120 and includes a tank 172 for storing liquid, for example water and cleansers. The user may pour liquid in the tank 172 through an inlet nozzle 173 located on the tank 172, or fill tap water in the tank 172 by linking the inlet nozzle 173 and a water tap. A spout 174 links the tank 172 and the container 110 and sends liquid out of the tank 172 in order to create a layer of water over the surface 116, which may stop the waste 150 staining and adhering on the surface 116. A water valve 176 connects the spout 174 and controls the flow liquid out of the spout 174. The water valve 176 may open the spout 174 and let the liquid flow, or may block the spout 176 and, therefore, stop the flow.
Furthermore, a second sensor 178 electrically connects the water valve 176. The second sensor 178 may sense the user's movement and send a signal to the water valve 176. The water valve 176 operates according to the signal. The second sensor 176 may be an infrared sensor, a pressure sensor, or a motion sensor. Take an infrared sensor as an example. The infrared sensor may detect the movement of the user while the user comes over, and turn on the water valve 176 to create a layer of water over the surface 116 before the user uses the toilet 100. The second sensor 178 may be a pressure sensor for detecting weight changing over the toilet 100 when the user sits on or leaves the toilet 100. Furthermore, the second sensor 178 may be a kind of sensor that is operated by a touch of the user.
In the foregoing, the pressure differential between the inside and the outside of the toilet 100 drives air flowing and therefore bring waste out of the toilet 100 instead of flushing. Therefore the toilet 100 may achieve the goal of water conservation.
Nowadays, toilets have become an indispensable part of our life. Toilets could be found in almost all public facilities and everyone's house, and most of them are flush toilets, which wastes large volumes of water. Therefore, the present invention provides a toilet seat that is used to install on a toilet, which the user already has, and cleans the toilet by using air pressure differential.
The toilet seat 300 includes the cover 120 and an inflator 130. The cover 120 can be put on the toilet 200 and shield an opening 112 of the toilet 200. Otherwise, the cover 120 can be lifted up and thus expose the opening 112. The inflator 130 connects the cover 120. When the cover 120 shields the opening 112, the inflator 130 supplies air into the toilet 200 for increasing the air pressure inside the toilet 200. While the air pressure inside the toilet 200 is higher than the outside of the toilet 200, the air pressure differential would drive air to flow and bring an waste 150 with it to the outside through a drain 114 of the toilet 200.
A seat 310 pivots on the cover 120 and interposes between the cover 120 and the opening 112 of the toilet 200. The seat 310 may be placed on the edge of the opening 112 for the user to sit on. On the other hand, the seat 310 may be lifted up to expose the edge. Of cause, there is a hole 312 on the center of the seat 310 to expose part of the opening 112.
The inflator 130 is a device that is used to force air into the toilet 200, for example an air pump, a compressor, a blower, etc. For example, the inflator 130 may be a kind of air pump that could be pushed down and squash air into the toilet 200.The inflator 130 may be driven by electricity or human force.
In addition, in order to seal the opening 112 for preventing air escaping from the opening 112, the toilet seat 300 has a lock 140 to lock the cover 120 tightly on the toilet 200. The lock 140 may be a fastener, a latch, a bolt, a pivot, etc. In the embodiment, the lock 140 comprises a mortise and a tenon located on the cover 120 and the seat 310 separately. When the cover 120 shields the opening 112, the mortise and the tenon may hold together and therefore locks the cover 120 tightly on the toilet 200.ln another embodiment, the lock 140 has a group of gear wheels between the cover 120 and the seat 310. The group of gear wheels may lock up after the cover 120 shielding the opening 112. The cover 120 remains over the container 110 until the group of gear wheels unlocked.
As described before, the toilet 200 is a common flush toilet, which may have a water tank 210 for storing water to flush. Water flows through a water outlet 212 into the toilet 200 while flushing. However, if the air pressure inside the toilet 200 increases, for the inflator 130 starting supplying air, air may escape through every opening on the toilet 200, which includes the water outlet 212. Therefore, the toilet seat 300 has a gas valve 320 for stopping air escaping through the water outlet 212. The gas valve 320 may allow fluid, such as gas and liquid, flowing from the water tank 210 to the toilet 200 and block flows in a reverse direction. Besides, the gas valve 320 may be a bung for plugging in the water outlet 212 or a lid for covering the water outlet 212.
The embodiment of the present invention is convenient for users to clean toilet in air instead of water. The users only needs to install the toilet seat on the toilet, which they already have, rather than replace whole sanitary equipment.
