Bath Water Recycling System

Abstract

A water recycling system for reprocessing and reusing bathing water from a bath or shower. The bathing water recycling system treats and reuses water that overflows from a bathtub or shower pan. The used bathing water is captured and retained after use. The captured dirty water is then filtered and purified. The filtered and purified water can be redistributed back into the shower or bathtub for reuse alone or in combination with additional fresh water. The treated water may also be rewarmed prior to reuse. Unneeded greywater water is redirected to the drain for disposal.

DETAILED DESCRIPTION

[0031] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They do not intend as an exhaustive description of the invention or do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0032] The present invention provides users with a combination bath and basin system designed to utilize water overflow from the bath to recycle and conserve water. The invention features a basin installed under the bath, catching overflow bath water, and allowing it to flow into a recycling and purification system. The invention may include a three-way valve so the water can be drained and sent into a filtration and purification system for recycling the water. The invention warms the filtered water and allows it to be redistributed back into the bath or shower. The invention offers a way to recycle and conserve water, ensuring users are more environmentally conscious of their water choices.

[0033] The present invention, in one exemplary embodiment, is an improved water conservation system used in conjunction with a bath or shower. The system is comprised of a bathtub or shower area with a basin surrounding the perimeter. The basin can be between approximately three and four inches in height to accommodate a significant volume of water for recycling into a pump and filtration system.

[0034] The filtration system may be attached to the bath via a three-way valve and several small, open grates. Water overflows from the bath, down into the basin area and then into the grates. Water is directed into the three-way valve for draining or to be sent into the filtration and purification system. The filtration system recycles and warms water, sending it back into the bath. The loop system conserves water while offering a way for people to relax and bathe without worry of wasting water.

[0035] Referring initially to the drawings, FIGS. 1-7 illustrate a bathing water recycling system 100. The bathing water recycling system 100 is configured for use in conjunction with a bath or shower. As illustrated in FIGS. 1-3, the bathing water recycling system 100 comprises a primary water collection component 110 and an overflow water collection component 120. The primary water collection component 110 may be a bathtub. The bathtub may be any type of tub, including, but not limited to freestanding, alcove, drop-in, corner, drop-in, or the like.

[0036] The primary water collection component 110 comprises a plurality of sidewalls 116 and a treated water inlet 114. The treated water inlet 114 is generally separate from the regular water inlet to the tub and may have a back-flow valve. As illustrated in FIG. 7, used bathing water may overflow the plurality of sidewalls 116 and down into the overflow water collection component 120 while a user is taking a bath. Alternatively, the primary water collection component 110 may further comprise a greywater outlet 112. The greywater outlet 112 penetrates one or more of the plurality of sidewalls 116 and leads to the overflow water collection component 120 as illustrated in FIG. 3.

[0037] The overflow water collection component 120 may be a catch basin 122 or water pan. The overflow water collection component 120 comprises a plurality of sidewalls 124. The overflow water collection component 120 is configured for receiving and retaining water overflow from the primary water collection component 110. The overflow water collection component 120 may be constructed from plastic or natural materials. The overflow water collection component 120 is positioned directly below or underneath the primary water collection component 110. The overflow water collection component 120 is wider and longer than the primary water collection component 110 so as to be able to collect and hold any overflow water. The overflow water collection component 120 is typically at least three inches in depth to be able to hold all of the overflow water.

The water recycling component 150 is configured to treat the overflow water. The overflow water may be mechanically filtered, chemically filtered, purified, or any combination thereof. The overflow water may also be reheated. The pump 140 is configured to redirect the treated water back into the primary water collection component.

[0040] As illustrated in FIG. 6, the water recycling component 150 may comprise a filtration element 152. The filtration element 152 is configured to filter the overflow water mechanically or chemically. The filtration element 152 may be a mechanical filtration mesh or ceramic pore structure filter, a chemical activated carbon absorption filter, a sequestration filter, an ion exchange resin filter, a reverse osmosis filter, or any combination thereof.

[0041] The water recycling component 150 may comprise a purification element 154. The purification element 154 is configured to purify the overflow water by sterilization. The purification element 154 may be an ultra-violet water sterilizer.

[0042] The water recycling component 150 may comprise a heating element 156. The hearing element 156 may be a metallic rod or other similar resistance heating element. The heating element 156 is configured to reheat the overflow water prior to reuse. Once the overflow water is treated, the pump 140 redirects the treated water back into the primary water collection bathtub 110 for reuse. The treated water mixes with bathing water in the tub to keep the water temperature constant with the clean bathing water.

[0043] The bathing water recycling system 100 may further comprises a controller 160. The controller 160 may be located on any part of the primary water collection component 110. The controller 160 is configures to operate the pump 140 and the three-way valve 130. The controller 160 directs the water overflow to the water recycling component 150 or to the greywater drain 132 of the three-way valve 130 as desired.
