Description

An automatic chamber {An automatic chamber}

The present invention keeps the base always open and at the same time, installs a pressure sensor on the base to recognize that it is in use when the load is applied and then removed, to open the base (move up or down). In order to prevent urine from being contaminated with the urine when men urinate, the toilet is equipped with a water saving device that automatically adjusts and supplies washing water by detecting stool and odor sensor and position sensor. Relates to an automatic toilet.

In general, when the toilet is flushed after use, water is uniformly supplied regardless of the urine, so much more water is wasted than necessary.

To compensate for this phenomenon, by dividing the amount of wash water supplied according to feces into the feces lever and the urine lever, it is selectively operated so that the amount of water used for urine treatment is discharged less than that of feces treatment. A water-saving device was developed so that it could be registered as Utility Model Registration No. 169255.

In addition, by installing the discharge valve operated by the urine lever in the discharge valve operated by the stool lever, if the lever is operated in the forward direction, the washing water discharge valve for the stool is operated. There is a valve-integrated water saving device that allows the valve to operate.

However, because the water saving device must be operated by the user must select the lever, the daily wet users often do not select the water saving lever inadvertently by selecting only the stool, so the water saving effect is not obtained. In addition, in the case of a public toilet used by many people, the user has a disadvantage in that an unpleasant feeling is required because the user has to manipulate a lever used by many people.

In addition, there is an automatic water saving device that automatically adjusts the amount of washing water by counting the time the user is sitting by installing a pressure sensor at the bottom of the toilet seat and determining the feces accordingly. The viewing time may be different, so the water saving device tends to malfunction, so it is not possible to obtain a substantial water saving effect. Also, since men urinate while standing, water (washing water) cannot be detected at this time. ), Or the user must flush the water directly.

On the other hand, the toilet seat is installed so that the seat and the lid is rotated in use in the state in which the seat is lowered, and after use is to press the lever to flush the water.

The toilets installed in the home are irrelevant, but the toilets used by many people are very reluctant to use them by hand because they are dirty.

In particular, when men urinate, the seat is left open after use, but sometimes people do unsanitary behaviors with the seat closed, so users who use it later become very uncomfortable.

In order to compensate for these phenomena, there are devices that open the pedestal by stepping on the footrest or automatically open and close the pedestal by a switch operation.

However, these devices still have a disadvantage that does not resolve the discomfort from the user, and automatic switching device is also inherent disadvantages.

In other words, the device for raising and lowering the base by stepping on the footrest is not only very inconvenient to use, but also has a disadvantage in that practical merchandise is inferior due to a crude structure.

In addition, there is a device that allows the base to be opened automatically by the elastic force of the spring, but this is not only inconvenient but also insecure because the user is automatically opened when the user wakes up for follow-up actions or for a short time after use. .

In addition, devices that raise and lower the seat using a switch have the inconvenience of operating the switch because the switch must be used to operate the seat, and without the voluntary cooperation of the user can not achieve the purpose. It is necessary to lift the base for the next user after use, because the operation may be cumbersome and troublesome, or the user may feel uncomfortable because the user tends to forget the next action and leave the toilet. to be.

The present invention was devised to solve the above-mentioned drawbacks. The object of the present invention is to install a pressure sensor on the seat and, after the user's load is removed from the seat, recognize that the user has completed the use of the toilet seat. Automatically open the user to keep the base open at all times except when the user is a female or stool so that the base is not contaminated with urine when men urinate. To provide an automatic toilet that can be used hygienically and hygienically.

In addition, the present invention is to operate the water-saving device to control the amount of water to be washed in accordance with feces by the smell sensor to be able to distinguish the urine more reliably, as well as to recognize the urine, even if men urinate can supply the wash water To provide a water-saving device to ensure that.

Another object of the present invention is that the seat can be opened and closed on both sides without opening and closing up and down, and can be used to adjust the body size by varying the size of the seat when used by adults and children, for example, depending on the user's body size To provide an automatic toilet.
