  • Patent number: 10166484
    Abstract: The post is preferably made in sections including a lower post section connected to a middle post section connected to an upper post section. A water conduit passes through the post or along the post to deliver water from the water outlet to the bucket. A pool is formed as an aboveground pool and preferably includes an inflatable ring at an upper edge of the pool. A pool cavity for retaining water is defined by the inflatable ring. The pool has a pool outlet connected to an outlet line. The outlet line delivers water to a water pump. The water pump delivers water to a pressurized water line. The pressurized water line is connected to a water conduit. The first arm and the second arm form a yoke that attach to sidewalls of the bucket.

  • Patent number: 7849530
    Abstract: The present invention relates to a household heat recovery device and more specifically to a wastewater heat recovery unit, which absorbs residual heat from the water flowing onto the floor and down the drain of an ordinary household shower or bathtub unit. In one embodiment, the heat recovery device adapts for ease-of-use and enables quick set-up in most existing and typical showers or bathtubs without any tools and without coupling to the existing plumbing. Internal passages direct the effluent shower water through a serpentine path to a discharge drain. Over time, the heat transferred from the water to the device then radiates into the environment—thus reducing the total energy cost for a household by reducing the thermal load on the main heating unit for the household.

  • Patent number: 7434745
    Abstract: A method and system for supplying temperature-controlled water to emergency shower and/or eyewash units (“SS/EWs”). In one embodiment, the water is circulated through a normally closed system containing a heat source such as a heat exchanger, a tank and pipes leading to the SS/EWs. Sensors in the system detect the temperature of the water and controllers regulate the amount of heat supplied to the heat exchanger to keep the temperature of the water in the system within a desired range of temperatures. A timer-controlled drainage subsystem periodically drains some or all of the water in the system. Water drained or supplied to the SS/EWs is made up by a cold water supply that feeds the heat exchanger. The system may use an alarm to signal water out of the desired temperature range, improper drainage, or water leaking from the system or being used by an SS/EW.

    Abstract: A heat recovery device is disclosed which is adapted for use in the drain conduit of standard shower installations having a hot water line, a cold water line, means for mixing water from both lines to deliver water at a suitable temperature to a shower head, and a drain conduit for disposing of waste water passing through the shower installation, the heat recovery device transferring heat from the waste water to cold water flowing to the cold water line. The heat recovery device has a first conduit connected into the drain conduit of the shower installation, and a second conduit connected into the cold water line leading into the shower installation and either wrapped around or inserted within the first conduit so that the second conduit is in operative heat transfer relationship with warm waste water passing through the first conduit, so that the incoming cold water is preheated by heat recovered from the waste water and transferred to the cold water.

  • Patent number: 5459890
    Abstract: A programmable electronic control controls water flow from a first electronically controlled valve assembly which receives water from the first water source, e.g. cold water. A second electronically controlled valve assembly is under the control of the programmable electronic control and controls the outflow of water received from a second water source, e.g. hot water. A mixing chamber assembly receives and mixes water coming from the first valve assembly and from the second valve assembly. A third electronically controlled valve assembly is connected to the mixing chamber assembly through a pipe and is under the control of the programmable electronic control. A temperature sensor assembly is connected to the programmable electronic control and senses water temperature at the third valve assembly. The temperature sensor provides a signal to the programmable electronic control representing the water temperature of the blended water sensed at the third valve assembly.

  • Patent number: 5301745
    Abstract: An installation for heat recovery from warm household drain water produced at household water consumption points, comprising a distributor tank, a first pipeline system which delivers warm household drain water from the consumption points to the distributor tank, a drain water channel, a heat exchange tank, and a second pipeline system which conveys warm household drain water to the heat exchange tank. The distributor tank has a first outlet leading into the drain water channel with a shut-off device which opens when the household drain water is below a predetermined temperature, and a second outlet into the second pipeline system when the household drain water in the distributor tank is above the predetermined temperature. Within the heat exchange tank is a coil containing cold drinking water which is heated by the household drain water.

  • Patent number: 5299329
    Abstract: A hot water camping or other outdoor shower releasably mounted to a motor vehicle utilizes water-to-water heat exchange through a heat exchanger mounted in-line with the vehicle heater core, and circulates the shower water with an electric water pump through removable hoses. The apparatus may use any source of water such as a lake or stream.

  • Patent number: 5233706
    Abstract: A shower stall includes a drain, wherein the drain includes a slide plate to selectively direct fluid to a sewage or selectively to a reservoir, wherein the reservoir includes a heater and pump assembly therewithin to effect heating and recirculating of the fluid from the reservoir. A modification of the invention includes the shower stall arranged to include a pneumatic or foam filled mattress, wherein the mattress is formed with drainage canals therealong to direct fluid to the floor drain and wherein the shower head is formed as a portion of a manifold assembly slidably directed along guide tracks to provide for displacement of the shower assembly relative to the shower stall.

  • Patent number: 5143149
    Abstract: A heat recovery system with a heat exchanger and a mixing valve. A drain trap includes a heat exchanger with an inner coiled tube, baffle plate, wastewater inlet, wastewater outlet, cold water inlet, and preheated water outlet. Wastewater enters the drain trap through the wastewater inlet, is slowed and spread by the baffle plate, and passes downward to the wastewater outlet. Cold water enters the inner tube through the cold water inlet and flows generally upward, taking on heat from the wastewater. This preheated water is fed to the mixing valve, which includes a flexible yoke to which are attached an adjustable steel rod, two stationary zinc rods, and a pivoting arm. The free end of the arm forms a pad which rests against a valve seat. The rods and pivoting arm expand or contract as the temperature of the incoming preheated water changes. The zinc rods expand more than the steel rod, flexing the yoke and rotating the pivoting arm.

  • Patent number: 4828709
    Abstract: A recirculating shower is especially adapted for showering a person's body with a relatively small supply of water. Before it is directed into the shower stall, the water is first recirculated through an alternate series loop pathway and concurrently cleaned and filtered as well as being heated to a desired temperature level. During the showering of the person's body the water continues to be recirculated, cleaned, filtered, and heated. When the showering is completed, the water is again directed through the alternate pathway for further cleaning and filtering, in preparation for a subsequent re-usage.
