United States Patent O 3,135,969 DEGDORANT DISPENSER Calvin E. Nolen, 12 Chase St., White Plains, N.Y. Filed (Ict. 19, 1961, Ser. No. 146,119 2 Claims. (Cl. 4--225) The present invention relates generally to improvements in deodorizing, cleaning and sanitizing devices and it relates more particularly to an improved device for use with toilet ilush tanks for automatically dispensing a predetermined amount of deodorant, sanitizing or other treating material which is normally in a solid state.
It is a common practice in the deodorizing of toilet areas to expose the area to the vapors slowly emanating from a normally solid or liquid deodorant or by suspending a solid cake of the volatile deodorant in the toilet bowl directly below the rim thereof. These practices possess numerous drawbacks. The deodorant is not only continuously dissipated even when not required but is of only limited effect since it does not directly treat the source of odor. There have been many devices proposed for automatically adding a deodorant or sanitizing material directly to the water in the toilet bowl following the ilushing thereof but these devices are unsatisfactory and have not been adopted. They are complicated and awkward devices, diilicult to attach and interfere with the proper operation of the ilush cycle. Furthermore, they frequently lead to unsanitary conditions and thus do not meet the requirements of the sanitary codes and otherwise leave much to be desired.
It is therefore a principal object of the present invention to provide an improved sanitizing device.
Another object of the present invention is to provide an improved sanitizing device for the deodorizing or disinfecting of toilet bowls and toilet areas.
Still another object of the present invention is to provide an improved sanitizing device for use with toilet flush tanks and automatically actuated with the flushing cycle to dispense a charge of sanitizing material into the toilet bowl.
A further object of the present invention is to provide a sanitizer dispensing device which is easily and rapidly mounted in the conventional toilet ilush tank and does not interfere with the normal operation thereof.
Still a further object of the present invention is to provide a sanitizing device of the above nature characterized by its simplicity, ruggedness and low cost.
The above and other objects of the present invention will become apparent from a reading of the following description taken in conjunction with the accompanying drawing, wherein:
FIGURE 1 is a fragmentary vertical sectional view of a toilet ilush tank provided with a sanitizer dispensing device in accordance with the present invention;
FIGURE 2 is a sectional view taken along line 2 2 in FIGURE 1;
FIGURE 3 is a top plan vieW of the sanitizer dispensing device; and
FIGURE 4 is a front elevational view of the top section thereof.
In a sense the present invention contemplates the combination comprising a toilet ilush tank including an overflow pipe and a filler tube, a reservoir chamber adapted to hold a solid sanitizing material, means affording iluid communication between said reservoir chamber and said overflow pipe, and a plenum chamber mounted on said reservoir chamber and communicating therewith at a plurality of levels, said filler tube having a discharge opening disposed above the level of communication between said reservoir chamber and said overflow pipe and directed into said plenum chamber. Another feature of the invention is the structure of the dispensing device, per se.
According to a preferred form of the dispensing device the reservoir chamber is of cylindrical configuration and is provided with a spout at the top thereof which extends across the upper edge of the overflow pipe to thereby support the reservoir chamber. The reservoir chamber and plenum chamber have a common dividing wall in which is formed a helically extending communication slot directed substantially tangentially to the inner face of the reservoir chamber; the slot being located along the edge of the plenum chamber.
Referring now to the drawing which illustrates a preferred embodiment of the present invention the reference numeral 10 generally designates a toilet ilush system employing a sanitizer dispensing device 11 in accordance with the present invention. The flush system 10 cornprises a ilush tank 12 and the associated valve and control arrangement of the conventional type including a pipe 13 connecting the tank 12 with the toilet bowl in the usual manner and coupled to a valve seat 14 mounted on the base of the ilush tank 12. A buoyant flush valve 16 of well known construction registers with the valve seat 14 and is limited to vertical aligned movement relative thereto by a stem 17 projecting vertically from the valve 16 and slidably engaged by a bracket 18 mounted on an overflow pipe 19. The overflow pipe 19 communicates with the toilet bowl by way of a coupling member 20 and pipe 13 and projects above the normal water level in the tank 12.
The upper end of the valve stern 17 terminates in a stop element 21 and is slidably engaged by a connecting link 22 depending from the free end of a pivoted valve opening lever 23. The lever 23 is manipulated in the usual manner by a lever disposed on the front face of the tank 12 and having a shaft projecting therethrough to permit the opening of the valve 16. The tank refilling system includes a vertical pipe 24 located in the tank 12 and connected by way of a coupling member 26 located in the base of the tank 12 to a source of water under pressure. A valve 27 is mounted atop the pipe 24, having its inlet connected to the pipe 24 and being controlled by a float 28 connected to the valve control member by a stem 29. The outlet of the iloat controlled valve 27 is connected to a tank filling pipe 30 extending toward the bottom of the tank 12 and to a ller tube 32 which unlike the normal arrangement is not directed into the overflow pipe 19 but is disposed as will be hereinafter set forth.
The dispensing device 11 is mounted on the overflow pipe 19 and is advantageously formed of a synthetic organic plastic material by injection molding or may be fabricated in any desired manner from other suitable material. The dispensing device 11 includes an open topped reservoir chamber 33 having a vertical cylindrical peripheral Wall 34 and a base 36. An outwardly downwardly inclined spout 37 projects from the upper border of the reservoir chamber 33 and is of substantially arcuate transverse cross section. The base of the spout 37 rests on the upper edge of the overflow pipe 19 the spout 37 being directed into the overflow pipe 17, and the chamber wall 34 extends along and in abutment with the pipe 19. In order to maintain the chamber 33 in its mounted position a lug 38 depends from and is integrally formed with the spout 37 and substantially abuts the inner face of the pipe 19.
An open topped plenum chamber 39 is associated with the reservoir chamber 33 and is formed integrally therewith. The plenum chamber 39 includes a peripheral wall 40 of substantially arcuate transverse cross section and extends helically along the chamber wall 34 opposite the spout carrying side thereof. The plenum chamber-.39 is separated from the reservoir chamber 33 by a section 41 of the wall 34 which is common to both chambers. The wall 40 extends above the wall 34 to permit overflow from the chamber 39 and through the chamber 33 and spout 37 into the overow pipe 19.` Communication between the plenum chamber 39 and the reservoir chamber 33 is afforded by an elongated slot 42 formed in the common wall section 41 and extending helically downwardly along said wall. The slot or opening 42 is disposed adjacent the convergence of the walls 40 and 41 and is directed substantially tangentially to the inner face of the chamber wall 34.
The dispenser 11 is applied to the flushing system 10 by merely bending the iiller tube 32 out of its normal registry with the overow pipe 19 and suspending the dispenser 11 on the overflow pipe 11 by the spout 37 in the manner illustrated, the lug 38 projecting into the pipe 19. The iiller tube is then bent with its discharge opening disposed above and directed into the plenum chamber 39. The ller tube 32 is generally formed of soft copper or brass and is readily deformable to the desired shape. The reservoir chamber 33 is fully or partially filled With a sanitizer 44 in solid form as cakes, nuggets, pellets, granules or the like which are so shaped or arranged as to permit the passage of water therethrough and therearound. The santitizer 44 is water soluble or readily water dispersible and may contain a deodorizer, disinfectant, detergent and other materials of any well known or desired composition.
In operation the toilet is ushed by raising the valve 16 in the usual manner by means of the lever 23. The tank 12 is emptied into the toilet bowl through the pipe 13, the valve 16 returning to its seated closed position upon emptying of the tank 12. The dropped water level in the tank 12 opens the valve 27 by means of the lowered tloat 28 and stem 29. In addition to relling the tank 12 through pipe 30 water flows through the filler tube 32 into the plenum chamber 39. From the plenum chamber 39 water flows through the slot 42 into the reservoir chamber 33 along the full length thereof in a tangent direction whereby a rotary motion is imparted thereto.
said reservoir chamber and an open topped plenum chamber mounted on said reservoir chamber, said reservoir and plenum chambers having a common dividing wall having an opening formedV above the bottom thereof affording communication between said chambers, said g reservoir chamber being of cylindrical configuration and such opening being a slot extending helically along said common wall.
2. The combination comprising a toilet flush tank includingan overflow pipe` and a ller tube, a reservoir chamber adapted to hold a solid sanitizing material, means affording fluid communication between said reservoir chamber and said overflow pipe, and a plenum chamber mounted on said reservoir chamber and communicating therewith at a level below the top of said reservoir chamber, and having a water feed opening formed in the top thereof, said filler tube having a discharge opening disposed above the level of communication between said reservoir chamber and said overow pipe and directed into said plenum chamber water feed opening and being in substantially free exterior communication, said reservoir chamber and said plenum chamber including a common cylindrical dividing wall, said wall having a vertically helically extending slot formed therein which is substantially tangent to the face of said wall inside said reservoir chamber.
The swirling water in the reservoir chamber 33 dissolves a predetermined amount of the sanitizer 44 and carries it over the spout 37 and by way of the overflow pipe 19 into the toilet bowl. Thus, the water in the toilet bowl References Cited in the file of this patent UNITED STATES PATENTS 1,170,387 Andrews Feb. 1, 1916 1,679,561 Cantrell Aug. 7, 1928 2,745,550 Atkinson May 15, 1956 2,978,299 Milne Apr. 4, 1961
