We live with too many chemicals: chlorine results in itchy skin and dry hair, thus chlorine removal from your shower water and reduction of dissolved solids is something you can do right now to combat this.
Water filtering means for attachment to or for use in conjunction with shower heads are known. These known filtering means may be inserted into a waterline, or replace an existing shower head, to filter water passing there through. However, after many attempts to solve the problems of clogging, ease in installation, back flushing and/or replacing the shower filter medium, as well as the high cost of manufacture, there still exists the need for a less cumbersome, easy to install and remove, low-cost shower filter assembly, that is also easily taken apart, to enable the filter element therein to be reversed for back flushing, thereby providing better water filtering capabilities, longer life of the filter element, and less waste.
One known prior art device is shown in U.S. Pat. No. 2,582,388 to Mansfield, which discloses a water filter for attachment to a water faucet having screwed together housings to enable the filter assembly to be opened for recharging the filter material therein. This patent also discusses the ability of the filter to be self-cleaning by reversing the filter on the faucet to reverse the flow of fluid through the same to flush out any impurities contained therein. This filter, however, is not readily adapted for use in a shower head for filtering out the impurities in hot water passing there through, and does not present or contemplate the reversing of a separate filter element contained within a shower filter, after unscrewing two portions of a housing.
In U.S. Pat. No. 4,993,080 to Rundzaitis et al., there is disclosed a shower filter having a replaceable filter cartridge. However, the replaceable filter cartridge is supported in a housing which is offset from the water flow, i.e., which is not in-line, thereby requiring direction control and valving means to direct the water from the entering water line into the offset filter cartridge.
U.S. Pat. No. 5,213,688 to Robinson, discloses a shower water filter, for insertion into a waterline, having a laterally displaced, or offset, cavity or compartment for holding a filter element. The filter element may be replaced by unscrewing a canister portion from a base portion, but no mention is made of reversing the filter element.
U.S. Pat. No. 5,300,224 to Farley, discloses a one piece shower water filter/dechlorinator assembly having a removable diverter/screen element at the inlet end to enable filter material to be initially inserted and held in the housing, as well as for recharging the filter, for dechlorinating water passing there through.
While the foregoing prior art patents solve some of the problems with the filtration and/or dechlorination of water in showers, they do not overcome all of the known difficulties, such as, but not limited to, problems with taking apart existing shower filters, back flushing of cartridges or filters to clean the same in an attempt to improve their efficiency and to avoid having to replace them as often, ease in manufacture and installation, and the provision of a continued, desired degree of filtration of water passing directly through an in-line device, providing extended filtering capabilities. Furthermore, while the above-mentioned prior art provide some limited improvements in the filtering art, there remains the need in the art for a shower filter assembly that provides a maximum of filtering and other capabilities in an easily opened design, allowing reversal or rotation of an internal filtering element, at a reasonable price.
Accordingly, it is a general object of the present invention to provide an improved multistage shower filter assembly. It is a particular object of the present invention to provide an easily opened multistage shower filter assembly. It is a still more particular object of the present invention to prove a shower water filter assembly in which an internal filter element to be easily reversed. It is a further object of the present invention to provide a shower water filter that unscrews to allow an internal filter element to be reversed and reinserted for back flushing, as required.
In accordance with one aspect of the invention, there is provided a multistage shower filter assembly having two separate housing members which are easily taken apart to allow an internal filter element to be reversed and reinserted for further use, so as to prevent the multistage shower filter from clogging and limiting the flow of water there through. The two separate housing members of the multistage shower filter assembly are provided with easily gripped external surfaces to make it as easy as possible to separate and reattach the housing members.
The objects and features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages, may best be understood by reference to the following description, taken in connection with the accompanying drawings, in which:
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide an improved shower water filter assembly.
It has been found by long use and experiment that there is so much water flowing through the filter material in a shower water filter that the multistage shower filter must be cleaned, i.e., backflushed, and/or the filter material or multistage shower filter actually replaced much more frequently than previously thought. In fact it is now recommended by some multistage shower filter manufacturers that the shower filter be backflushed at least every thirty (30) days. In addition, depending on the quality of the water in a given area, and the temperature of the water flowing through the shower filter, the length of time between backflushing and/or changing may be shortened even further. However, with known shower water filters it is not convenient to backwash the filter and/or change the filter medium.
The device of the present invention provides for an easily opened device in which a shower water filter may have its internal filter, containing the filter media backflushed at regular intervals. Turning now to the drawings,
The top portion 2 includes a securing means, such as an annular threaded lower portion 20, which cooperates with and is securely held in a further securing means, such as an internally threaded annular upper portion 17 of bottom portion 10. The annular internal threads of bottom portion 17 are secured to the annular threaded lower portion 15, in any desired manner, such as by a user holding onto a gripping area 3, 9 formed on the external surfaces of both the top portion 2 and bottom portion 10 and screwing the portions into each other. To allow the top and bottom portions to be more easily gripped and turned, gripping or non-slip means, such as a plurality of ribs 5 are formed integrally with the top and bottom portions 16, 10, in reduced diameter gripping areas 3, 9.
As shown, the assembly 4 is preferably substantially cylindrical in shape with substantially domed ends. The top portion 2 includes a raised lip 6 below gripping area 3, while bottom portion 10 includes a raised skirt, or the like 8, formed above the gripping area 9. Therefore, when the top and bottom portions 16 and 10 are screwed together, raised lip 6 and raised skirt 8 cooperate to form a raised central area 7 on the assembly 4, as shown in
When the top and bottom portions 16, 10 are assembled, an internal, hollow filter chamber 12 is contained within the assembly 4 and is bounded by the top and bottom portions. A filter element 19 is captured within the internal chamber 12, and includes a substantially flat, circular top wall 14, having a screen or the like therein to allow water from the inlet 1, to flow in the direction of the arrows, through the same, into an inner chamber 16 formed by an annular side wall 18. A substantially flat, circular bottom wall 20 having a further screen therein is secured to the other end of annular wall 18 to allow water to flow out the outlet 11 after having passed through filter media in the filter element 19. The walls 14, 18 and 20 of the filter element 19 are secured together in any desired manner, such as by being permanently bonded together with any desired filter media 21 filling inner chamber 16.
The upper and lower portions 16 and 10 of assembly 4 may be fabricated in any desired manner, using any acceptable material, such as by molding a plastic material to form the two portions in such a manner that they are sized and dimensioned so as to be capable of being easily sealingly screwed together and apart.
In use, the filter element 19 is first assembled with filter media 21 therein, and inserted into one of the upper and lower portions 16 and 10. These portions are then screwed together until the filter element 19 is securely held in chamber 12, between internal wall means 46, 48. To prevent water from bypassing the filter element 19 in the internal chamber 12, sealing means, such as O-ring seals 13, 52, are inserted and held in annular openings formed in each of the internal wall means 46, 48.
After having been used for a predetermined period of time in a shower, depending on the water being used, the filter media 21 in the filter element 19 will become partially blocked or clogged, thereby loosing its effectiveness and slowing down the flow of water through the multistage shower filter assembly 4. However, the upper and lower portions 16 and 10 may then be easily screwed apart, with the upper portion still attached to the shower arm, by gripping the gripping areas 3 and 9 and turning the same so as to separate the top and bottom portions and open the internal chamber 12. The filter element 19 may then be easily removed and reversed, i.e., turned 180 degrees, and the portions 16 and 10 screwed back together with the filter element 19 in this reversed position. Further flow of water through the reassembled filter, with the filter element 19 in the reversed position, will backflush the filter media 21 in the filter element to provide continued efficient use of the filter media in the filter element, and thereby provide for a longer useful life thereof, as well as the elimination of waste, some of it toxic, as occurs with current filters, which require the filter element and/or filter media to be discarded once blocked or clogged.
Accordingly, as will be apparent to those skilled in the art, the assembly of the present invention provides considerable advantages in ease and flexibility of manufacture, as well as the separating of the separate portions of the assembly, and the installation and removal of the filter element contained therein.
Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
