  However, it has been pointed out that even a water-degradable sanitary napkin is inferior in water-decomposability in the portion where the adhesive layer is formed. In Patent Document 2, in order to solve such a problem, a technique for improving an adhesive layer forming means and an adhesive is disclosed, and it seems that a certain effect is obtained. Even if it exists, it is desirable to disperse more finely in a shorter time as long as it is flushed into a flush toilet.

  On the other hand, the penetration rate of such water-decomposable sanitary napkins is still low at present. For this reason, it is not often carried out as it is in a toilet or the like, and is generally collected by installing a dedicated trash can. Collecting and disposing of used sanitary items from dedicated trash bins in parks, station toilets, hotel toilets, etc. used by many people not only requires a lot of labor and cost, but in recent years It is becoming difficult to secure these workers. Therefore, even if it is not water-degradable, if it does not cause clogging in the drain pipe, it can be drained as it is, and if it can be collected together with filth from the sewage tank or septic tank, the labor of collection from the trash can be saved. Cost can be greatly reduced.

  DISCLOSURE OF THE INVENTION The present invention has been made in view of the above, and it is possible to dispose of used sanitary goods with water and to dispose of the sanitary goods disposer and sanitary goods that can be disposed of through a drainage facility such as a flush toilet. It is an object to provide a method.

According to a second aspect of the present invention, there is provided the sanitary article disposer according to the first aspect, wherein the water supplied from the water supply pipe is set to flow when the housing opening of the casing is closed. The task is to do.
According to a third aspect of the present invention, there is provided a sanitary article disposer according to the first or second aspect, which is installed in a toilet.
According to a fourth aspect of the present invention, there is provided a method for treating a sanitary product, characterized in that the sanitary product for disposal is crushed by a crushing means, and then the sanitary product crushed with water is pushed into a discharge pipe for disposal. .

  According to the present invention, used sanitary goods for disposal are pulverized by the pulverizing means, so that they can be directly washed away with water and disposed through a drainage facility such as a toilet. Therefore, in the case of a water-decomposable sanitary napkin or the like, it is possible to prevent the drain pipe from being clogged even if it is dispersed in water more quickly and used continuously in a public toilet or the like. Even in the case of sanitary goods that are not water-degradable, they can be washed away with water as they are finely pulverized, so that they can be recovered from septic tanks and sewage tanks. The labor and cost of recovering from can be significantly reduced. In addition to water-degradable, non-water-degradable, sanitary items that are expected to be discarded below a predetermined number of buildings and facilities of a predetermined scale, a prescribed legal As long as it does not violate regulatory requirements, it can be discharged directly into sewage treatment facilities.

  Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. In the figure, reference numeral 1 denotes a sanitary article disposer of the present embodiment. The sanitary article disposer 1 includes a casing 2 and a pulverizing means 3.

  The casing 2 is formed with an accommodation port 21 for receiving a used sanitary product that is to be discarded. A lid member 22 is attached to the accommodation port 21 so as to be openable and closable. When the sanitary article is discarded, the lid member 22 is opened and accommodated in the casing 2 through the accommodation port 21. The lid member 22 is not limited as long as it can cover the accommodation port 21. For example, as disclosed in JP-A-11-292208, a cover portion that covers the accommodation port 21 when closed. And it is preferable to use what was formed in the substantially L shape seeing from the side which has the receiving part which covers the accommodating port 21 at the time of opening. When such a lid member 22 is used, the inside of the casing 2 is concealed by the receiving portion even when opened, and there is an effect of preventing the user from feeling uncomfortable.

  The lid member 22 may be manually opened and closed, or may be configured to be provided with a tread plate and opened when the tread plate is stepped on. In addition, a sensor may be provided so that it automatically opens and closes when a hand is brought closer.

  The shape and size of the casing 2 are arbitrary, as long as the crushing means 3 can be accommodated and held, and a predetermined amount of sanitary goods to be discarded can be accommodated. The pulverizing means 3 disposed in the casing 2 may be any one that can finely pulverize the synthetic resin and fibers constituting the sanitary article. For example, a rotating blade with a cutting blade spirally formed around the rotating shaft, a rotating spring with a sharp cutting edge, a cylindrical rotating body with a cutting blade on the inner peripheral surface or bottom surface, Alternatively, it is possible to use a combination of two or more of these appropriately arranged. Since the sanitary article has an adhesive layer, it is preferable to combine two or more of them in order to pulverize more reliably. The surface of the cutting blade is preferably made of a material that does not adhere to the adhesive layer. Further, when the pulverized sanitary goods are pulverized by the pulverizing means 3, they are provided in the vicinity of the discharge pipe 5 to be described later so as to be sent near the lower portion of the casing 2 in this embodiment. When the crushing means 3 is operated, an operation switch can be provided near the upper portion of the casing 2 and the operation switch can be turned on to operate. However, the crushing means 3 is automatically driven when the lid member 22 is closed. It is preferable to adopt a configuration to do so. For maintenance of the pulverizing means 3, it is preferable that the manual mode and the automatic mode can be switched arbitrarily.

  A water supply pipe 4 is connected to an appropriate upper position of the casing 2. The water supply pipe 4 is provided so that the pulverized sanitary goods sent to the vicinity of the lower portion of the casing 2 can be washed away and sent to the discharge pipe 5. Therefore, it may be provided at a position where water can be supplied from above the sanitary product pulverized by the pulverizing means 3, but is preferably provided at a position where water can be supplied from above the pulverizing means 3. Thereby, the bodily fluid etc. adhering to the cutting blade of the grinding | pulverization means 3 can also be washed away together. Of course, the water supply position is not limited to one location, and may be provided at two or more locations such as the upper and lower portions of the crushing means 3.

  For example, the water supplied from the water supply pipe 4 can be branched from a pipe supplying water for cleaning the flush toilet 10 and introduced into the casing 2. In supplying water from the water supply pipe 4, for example, a sensor may be provided so that water is automatically supplied when the lid member 22 is closed. In addition, for example, a push button may be provided on the upper portion of the casing 2 to supply water manually.

  The discharge pipe 5 is provided in the lower part of the casing 2. The discharge pipe 5 is connected to a drain pipe 11 that constitutes the drainage facility of the flush toilet 10, and the pulverized sanitary goods are sent to the drain pipe 11 of the flush toilet 10 via the drain pipe 5 to the waste water treatment unit. Sent.

  The sanitary goods disposer 1 of this embodiment is installed for every private room booth of a public toilet, for example. The user throws in used sanitary goods from the accommodation port 21 of the casing 2. For example, when the lid member 22 is closed, a large amount of water is supplied from the water supply pipe 4 and the crushing means 3 is driven to crush the supplied sanitary goods. The pulverized sanitary goods are washed away by water, sent to the discharge pipe 5, and further sent to the waste water treatment section via the existing drain pipe 11 provided in the flush toilet 10.

  According to this embodiment, used sanitary goods can be finely pulverized. Therefore, for example, if it is a water-degradable sanitary article, it can be finely dispersed in water in a shorter time than when it is directly passed to a flush toilet, and the drain pipe 11 can be made more difficult to clog.

  Even if it is not a water-degradable sanitary product, it can be pulverized finely, so that it can flow into the drain pipe 11 of the flush toilet 10. If it is not a water-disintegratable sanitary product, it will not dissolve even if it is finely pulverized by the sanitary product disposer 1 of this embodiment, but it will collect in the sewage tank or septic tank, but it can be collected together when collecting the filth. Compared to sanitary trash bins, the labor and cost of collection can be greatly reduced. In addition, for example, in the case of a building or facility where the amount of sanitary goods discarded is predicted to be less than a predetermined amount, it should be discharged directly into sewage unless it violates the legal regulations of the construction area of the building. Is also possible.

It is a conceptual diagram which shows the disposer for sanitary goods which concerns on one Embodiment of this invention.
