Abstract

(57) [Abstract] [Purpose] The present invention can automatically clean the filter core,
Therefore, it is intended to provide a water purifier capable of keeping the filter core clean. [Structure] A rotator that is rotated by the force of water flowing into a water purifier is provided with a roller brush that can rotate while being in contact with around a filter core. By rotating the roller brush, foreign matters adhering to the surface of the filter core are scraped off. The shredded foreign matters are flushed out of the water purifier when the water is discharged from the flush water valve. Further, the inflowing water passes through the filter core, is filtered, and then flows out from the drinking water valve as drinking water. [Effect] Foreign matters adhering to the surface of the filter core are brushed off by a roller brush and discharged together with the wash water, and the drinking water is always filtered by a clean filter core to keep it clean.

[Industrial applications]

 The present invention relates to a water purifier that can be used by being attached to a tap of a water supply, and more particularly to a water purifier that can automatically clean a filter core.

[0002]

[Prior Art]

 Although the development of industry has brought convenience to human life, it is also true that the environment is considerably polluted. In particular, pollution of water sources has become a serious problem every day, and the tap water we drink on a daily basis has undergone special treatment, but due to excessive pollution of water quality, microorganisms contained in it The reality is that the sand quality and miscellaneous materials are several times higher than before. So, for the sake of health, we asked people to drink clean water. There is.

Although there are various types of commercially available water purifiers, all of them purify water by filtering miscellaneous dirt using graphite, fiber, ceramics or activated carbon as a filter medium. When these water purifiers are used for a certain period of time, the filter core must be taken out and washed, or the filter core must be replaced.

However, since the general public is busy or lacks knowledge of cleaning the filter core, it is often used for a long period of time without changing the filter core as it is, and it is used with a large amount of dirt attached to the filter core. This not only affects the amount of water discharged, but also becomes a place where pathogenic bacteria inhabit, which rather causes harmful effects. In addition, if the method of cleaning the filter core is incorrect or careless, the filter core is likely to be damaged, and the filter core must be replaced with a new filter core, which causes a loss. There were often cases.

[0005]

[Problems to be solved by the device]

 Therefore, the present invention provides an automatic filter-cleaning water purifier that can automatically clean the filter core during use, thereby avoiding the risk of the filter core being contaminated or affecting the amount of water discharged. Is what you are trying to do.

[0006]

[Means for Solving the Problems]

 According to the present invention, a filter core automatic washing type water purifier is mainly composed of an outer shell, a filter core gasket, a rotator, a roller brush, a lid gasket and an upper lid, and the rotator is rotated by the impact of running water. The attached roller brush is used to polish away foreign matters adhering to the surface of the filter core and automatically clean the filter core to keep the water quality clean.

Among them, the filter core is attached by bolts integrally with a rotor having an upper body, a lower body, and a floating body and an impeller. A few rotating roller brushes are attached to the periphery between the upper, lower, floating body and impeller, and a water inlet with a specific injection angle is provided at the position inside the outer shell facing the upper and lower impellers. Be done.

[0008]

[Action]

 When water is supplied for drinking or washing, the impeller rotates due to the impact of the water supply, and therefore the rotation of the rotating machine causes the roller brush to polish away foreign matters adhering to the outside of the filter core and automatically remove the filter core. The purpose of washing and keeping water quality can be reached.

The structure, features and effects of the present invention will be described in detail with reference to the drawings in order to understand the details in the following examination.

[0010]

【Example】

 As shown in FIG. 1 and FIG. 2, the automatic filter core cleaning type water purifier according to the embodiment of the present invention has one gasket at the protruding portion of the pipe connecting the inner center of the outer shell 1 and the drinking water valve 11. 31 (filter core gasket) is placed, the filter core 3 is attached on it, the upper lid 2 is screwed to the top of the outer shell 1 through the lid gasket 21, and the filter core 3 is pressed and fixed at the central position. ..

On the outside of the filter core 3, a rotator A having a floating body 4, 4 ′ and impellers 41, 41 ′ mounted on the upper and lower sides, which is assembled with a bolt 5 and a nut 51, is attached. The upper and lower impellers 41, 41 'are provided with a few convex columns 42, 42' on the symmetry planes, and the roller brush 6 having shaft holes 61 at both ends of the booklet is fitted so as to be freely rotatable. A water inlet 13 having a specific injection angle is provided at a position facing the lower impeller 41, 41 'inside the outer shell 1, respectively.

[0011]

[Effect of the device]

 As a result, when the drinking water valve 11 or the wash water valve 12 is opened, the impellers 41 and 41 'move due to the impact of water flowing out of the water supply port 13 to rotate the rotator A. The brush 6 can polish away foreign matters attached to the surface of the filter core 3. Therefore, when the wash water valve 12 is opened and water for washing hands and goods is discharged, foreign matters adhering to the outside of the filter core 3 directly flow out from the wash water valve 12 without being filtered, but drinking water is used. People are always kept clean.
