Description:
BACKGROUND

Water is a scare resource and there are many devices that manage home water consumption like new products taking aim at water consumption in the shower. It is important to mention that the innovator named above is also the innovator of the device proposed in a provisional patent application at South Africa Patent Office (CIPC) with number 2016704993 that will laps on 19/07/2017.

The previous innovation refers to hot and cold water outlets. The hot water coming from the geyser has for some time, a temperature lower than the user wants and only gradually starts heating up. The cold water is lost until water has the required temperature. The innovation consists in saving the cold water in an athatched container until the water temperature heats up to the temperature required.

These innovations, as this one, are water- saving devices categorized as "smart" or "intelligent" with onboard sensors and controllers between the shower pipe and the shower head and have connections to a smartphone app. These devices are complex and require mobile connectivity.

The present proposal of a water consumption saving device is based on saving water wasted in shower during the starting of water flow with a low temperature and saving the cold water in an additional container until the water will have the temperature that was setup by the user. The temperature is calculated by an automated computation device like PC, mobile, tablet, etc. using formulae that depends of the distance of the shower from the geyser, the exterior temperature, die weather and other conditions that influence the water flow temperature. Once calculated, the temperature is setup by the user by using the control panel. The panel includes a second switch or a button for the setup of the duration of the shower.

Furthermore, the panel has an option for the user to dispense a cleaning liquid, soap or shower gel together with the water flow. If the user wants to use this option, an on/off switch will be available. If the container, where the cleaning liquid is stored, is empty, a red light (LCD) for empty and green light (LCD) are switched on to inform the user.

Furthermore, the device integrates sensors and data collection with the accompanying app, allowing users to track their water usage and habits and compare that data with others that are also using the device. All functions presented above achieve a 70% or more water saved during the shower. BRIEF SUMMARY OF THE INVENTION

The main idea is to make the shower controlled by presets using a mobile app that can calculate the temperature chosen by the user after a formulae depending of the distance from the geyser, average shower time, weather and the water temperature that the user wants to shower with. The app should allow for easy access to presets so that water temperature can be changed quickly. The app will use the presets to determine the time it will take for the shower to reach the correct temperature. The app should also display the water usage per user, as well as work out and display a monthly average. The app should allow setup for multiple users, each with their own preset that can be activated manual or via the app before showering.

The water usage can be measured using a water flow meter. For the usage to be measured accurately the user must calculate his own flow rate. The app communicates with the PC board equipped with a SIM card, part of the smart shower and the mobile network. Should the user not be connected to a network, the PC board should store the data.

The device could also include a compartment containing liquid soap or shower gel that will be mixed with the water by turning a mechanical bypass valve (tap). The water will be diverted through the compartment introducing the soap/gel to the water and then the water will rejoin the normal water flow and flow out through the shower head. The soap will enter the soap container compartment through a gravity hole. A sensor can detect the level of the soap/gel and alert the user when the dispenser is empty.

The dispenser gel/soap canister has to be custom manufactured. An effective battery can be used to power the device as a second solution to standard electrical supply.

DETAILED DESCRIPTION AND BEST MODE OF IMPLEMENTATION

In Figure 1 and 2 reference numeral 10 refers to a mobi shower power as the water conservation device which includes a water inlet port 12 and two water outlet ports 14, 16 in fluid flow communication with the water inlet port 12.

The water saving device 10 also includes two valves 18, 20 for controlling the passage of water from the water inlet port 12 through either of the two outlet ports 14, 16.

The mobi shower power 10 further includes a temperature sensor 22 for determining the temperature of water entering the device S through the water inlet port 12 and a controller 24 in communication with the valves 18, 20, the controller receiving temperature readings from the temperature sensor 22 and determining through which outlet the water flows, based on the temperature readings.

The water inlet port 12 is connectable to a warm water supply. As shown in Figure 2, in this example the warm water supply is in the form of a household warm water supply. The two water outlet ports 14, 16 are in the form of storage water.

Outlet port 14 and a usage water outlet port 16. The usage water outlet port 16 is connected to a water dispensing fixture 102. The storage water outlet port 14 is connected to a storage tank 104. In (his example the water dispensing fixture 102 is in the form of a shower head.

The device includes a valve 18, 20 associated with each outlet port 14, 16 respectively. The valves 18, 20 are in the form of electromechanical valves.

The mobi shower power 10 also includes a relay 26 and a relay driver circuit (not 25 shown). The controller 24 controls the opening and closing of the valves via the relay 26. The mobi shower power 10 also includes a power supply unit (PSU)

The device further includes a pipe arrangement for connecting the water inlet port 12 to the two water outlet ports 14, 16.

The pipe arrangement 7 includes a T-piece pipe, pipe connecting pieces, thread connectors and pipe elbow for connecting the water dispensing fixture 102. The pipe arrangement is in the form of galvanized components.

In this example the device also includes a water inlet pipe 106 connecting the warm water source to the water inlet port 12. The device also includes a drain pipe 108 connecting the storage water outlet port 14 to the storage container 104.

The mobi shower power 10 includes a housing 30, having the water inlet port 12 and water outlet ports 14, 16 provided through an outer wall of the housing 30. The housing 30 includes two compartments separated by an inner wall IS, an upper compartment housing the electrical components of the device and a bottom compartment housing the water flow components.

The inner wall 32 includes an aperture to enable a connection between the electrical components and the water flow components.

The temperature sensor 22 is in the form of a sealed temperature sensor. The temperature sensor 22 is incorporated in the pipe arrangement, in use to measure the temperature of water entering the device through the inlet port 12.

The controller 24 is in the form of a microcontroller, specifically a 25 Arduino controller. The controller 24 is pre-programmed with a threshold temperature value. In use, when the temperature of water entering through the water inlet 12 is below the threshold temperature, the controller 24 opens the valve 18 associated with the storage water outlet port 14 and closes the valve 20 associated with the usage water outlet port 16. The water thus flows through the storage water outlet port 14, through the drain pipe 108 to the storage container 104.

When the temperature of water entering through the water inlet port 12 is equal to or above the threshold temperature, the controller 24 opens the valve 20 associated with the usage water outlet port 16 and closes the valve 18 associated with the storage water outlet port 14. The water thus flows through the usage water outlet port 16 to the showerhead 102.

In this example the threshold temperature is 32 °C. As shown in Figure 2 the mobi shower power 10 is installed in a shower. The water inlet port 12 is connected to the warm water supply of the shower. The device will cause all water entering the device, which is below the threshold temperature, to be stored in the storage container 104, and will only feed the showerhead with water, once water that is equal to or above the threshold temperature enters the water inlet port 12.

Advantageously, the unwanted cold water that is initially passed from IS the warm water supply is stored in the storage container 104 and not wasted as conventionally would be. In fig. 3 the mobi shower power innovation design is changed by reconfiguring the PC board to use the preset from the user or from the automated calculator plus the setup of shower duration and setup of gel dispensing option. Furthermore, the PC board installed has a statistic function attached for calculating the average of water consumption per month or per user.
