Drop-in water dispenser {POUR-THROUGH WATER TREATMENT DISPENSER}
[2] Household water treatment devices are known in the art. These devices are self contained systems that treat water in batches. Examples of batching devices are features / household vials, in which treated water is injected through a spigot, and larger dispensers. Such systems typically have a top and bottom chamber separated by a filter cartridge. In general, these devices are called " pour-through " devices because water is transported by gravity from the upper chamber to the lower chamber through the cartridge.
[3] One of the disadvantages of the drop injection dispenser is that the size and shape are not optimized. Such a dispenser is not only wider than necessary, but also short and low in length and height. In addition, the dimensions and shape of the dispenser are not optimized to fit underneath the faucet of a conventional kitchen sink when the inlet tray is filled.
[4] As a result of the recent development of filter membranes in direct injection devices, biological contaminants such as protozoan cysts (eg, cryptosporidium) can be removed. However, if the treated water is contaminated with untreated water, there is no point in successfully removing biological contaminants with the filter cartridge. No contamination can be tolerated, even with very small amounts of biological contaminants, making the treated water unsuitable for drinking.
[5] One path where treated water is contaminated by untreated water in the direct injection dispenser is when the injection tray in the sink is filled. Users often first turn the stopper to move the fill tray to fill the dispenser. As the water stem passes through the top edge of the tank and the inlet tray, untreated water can flow between them and enter the bottom of the tank.
[6] Another problem arising in the drop injection dispenser is due to the high content of water. Users often carry the dispenser from the sink to the refrigerator (or other location) shortly after filling the fill tray. Untreated water present inside the injection tray will rock back and forth causing the dispenser to become unstable, causing water to splash out of the injection tray.
[7] Therefore, there is a need for a tank / injection tray shape with optimized dimensions and shapes for better separation of treated water from untreated water, and an injection tray shape that reduces water ripple in the inlet tray.
[8] [Summary of invention]
[9] A first aspect of the invention relates to a water treatment dispenser comprising a tank for receiving treated water, an injection tray inserted in the tank and a cover covering the injection tray. The length of the dispenser is at least twice the width.
[10] A second aspect of the invention relates to a water treatment dispenser comprising a tank for receiving treated water and an injection tray inserted in the tank. At this time, the dispenser has a height of 9.0 inches or more and 11.0 inches or less.
[11] A third aspect of the invention relates to a water treatment dispenser comprising a tank for receiving treated water, an injection tray inserted in the tank and a cover covering the injection tray. Typically the injection tray has a downward passage around the periphery where the upper edge of the tank is inserted.
[12] A fourth aspect of the invention relates to a water treatment dispenser comprising a tank for receiving treated water, an injection tray inserted in the tank and a cover covering the injection tray. The injection tray has a baffle extending inside the injection tray.
[13] These and other advantages and novel aspects which characterize the invention are specifically indicated in the claims appended hereto. However, in order to better understand the present invention and its advantages, reference should be made to the drawings, which form a further part of the present invention, and to the additional description disclosed and described as preferred embodiments of the present invention.
[1] The present invention relates to a pour-through water treatment dispenser. Specifically, the present invention has a tank / pour tray shape of dimensions and shape that is optimal for better separation of treated and untreated water, and the carrier material in the inlet tray. A dispenser with a baffle in an injection tray to reduce this slack.
[24] Preferred embodiments of the invention will be described with reference to the accompanying drawings in which like reference numerals coincide with corresponding parts.
[25] 1 is a perspective view showing a water treatment apparatus according to the present invention with the cover removed.
[26] 2a is a cross-sectional view of the device shown in FIG. 1.
[27] FIG. 2B is a cross-sectional view of a portion of the device shown in FIG. 1, showing a cross section of the cover, the fill tray and the tank. FIG.
[14] The water treatment device 10 includes a tank 20, a pour tray 30, a lid 40 and a filter cartridge 60. The device 10 is also used as another direct injection device. The injection tray 30 is filled with tap water. By gravity, water flows through the filter cartridge 60 and into the tank 20. In the case of the dispenser shape described herein, users inject the treated water from the tank 20 through the stopper 50.
[15] The device 10 is sized and configured to optimally use a space that can be accommodated in most refrigerators. Since the device is long and narrow (length more than twice its width), it occupies a minimum of the space of an acceptable front shelf, while the space of the rear shelf is not wasted. In addition, the device provides an additional space utilization advantage since the height is relatively similar to the height of the milk carton. Specific dimensions of the preferred device are as follows: height H1 (total of cover 40) is 10.25 inches; Width W is 5.50 inches; And length L is 15.38 inches. These dimensions can be varied without departing from the spirit of the invention, and can be made with dispensers having different sizes but relatively narrow, long and tall.
[16] The device 10 is also sized and shaped to fit most kitchen sinks. The length dimension L is short enough to fit obliquely or vertically to the sink. The narrow width dimension W of the device 10 and the rounded end 12 allow the device to be easily obliquely fitted to the sink. The height H2 of the device 10 with the cover removed should also be low enough to allow the device to enter under the faucet of a conventional sink. The height H2 in the preferred embodiment is 9.51 inches, but may be slightly higher or lower without departing from the spirit of the invention.
[17] The infusion tray 30 and the tank 20 are filled with untreated water when the inlet tray 30 is filled or when the device 10 is transported. The inlet tray 30 and the upper edge of the tank 20; 22) so that it does not flow in between. The infusion tray 30 includes an upper lip 37 extending outward from the nearest top of the infusion tray 30 and present over the upper edge 22 of the tank 20. The protruding wall 38 extends downward from the outer end of the lip 37 along the outer side of the upper wall 21 of the tank. In this way, the downwardly facing channel 36 is formed such that the upper edge 22 of the upper wall 21 of the tank 20 is inserted. It will be appreciated that the shape and orientation of the channel 36 and the position on the injection tray 30 may vary. The overhanging wall 38 preferably secures the injection tray 30 on the tank 20 to help prevent untreated water from flowing into the tank 20 and is not necessary. . The channel 36 and the lip 37 need not be molded as part of the injection tray 30 but can be separated as a form attached thereto. The upper edge 22 of the tank 20 need not be the top of the tank, but may be located at a lower portion of the tank 20.
[18] The cover 40 is located on top of the device 10 after the device is filled. The cover 40 may be secured on the injection tray 30 by a peripheral wall 42 surrounding the fixed wall 39 extending upward from the lip 37. The bottom of the peripheral wall 42 abuts the top surface of the lip 37.
[19] The injection tray 30 includes a baffle 33. When the device 10 is carried by a finger hold 23 in the tank 20 (ie, the injection tray 30 will have a shape corresponding to the jaw 34 of the tank 20). When present, the water present in the injection tray 30 may sway back and forth, making the device unstable, whereby water may be splashed out of the injection tray 30 and discharged. The baffle 33 prevents this phenomenon. In a preferred embodiment, they are vertical walls extending vertically from the inner sidewall 35 of the injection tray towards the interior of the injection tray 30. They are located facing each other at the center of the injection tray 30. The number, shape and location of the baffles can be varied without departing from the spirit of the invention.
[20] Referring to FIG. 2A, the injection tray 30 is pointed downward toward the sleeve 32 such that all the water in the injection tray 30 is discharged through the filter cartridge 60. Similarly, as best shown in FIG. 1, the injection tray 30 is also pointed downward along the centerline so that all of the water present on the baffle 33 facing the filter cartridge 60 is flush with the filter cartridge. Discharged to (60).
[21] The filter cartridge 60 is attached to the sleeve 32 by an O-ring 62. It will be appreciated that a number of filter cartridges with various membranes may be used within the scope of the present invention.
[22] Treated water is injected from the tank 20 through a stopper 50. The stopper 50 includes a valve 52 movable by the lever 54 between an open position and a closed position. The stopper 50 is attached to the stopper outlet 27 of the tank 20 by an O-ring 56. Since the bottom of the plug outlet 27 and the bottom of the valve chamber 53 are located very low in the tank 20, ie below the tank bottom 25, water can be completely discharged from the tank 20. The base 24 lifts the tank 20 up so that the bottom of the stopper 50 does not contact the shelf or other surface of the refrigerator in which the device 10 is located.
[23] It is to be understood that the invention is not limited by the preferred embodiments described above, but is merely illustrative. To the extent that without departing from the spirit of the invention, modifications throughout the scope indicated by the general meaning of the terms in which the appended claims are expressed, in particular in the form, size and arrangement of the parts or materials of the component parts, Can be done.
