DETAILED DESCRIPTION OF EMBODIMENTS

(10) The present invention relates to a wash/shower system designed to provide a hot-air/water suspension. The basic principle of the system is a heated air stream saturated with miniaturized water droplets. The system is a comprehensive wash/shower solution that uses a heated air stream saturated (or significantly saturated) with water. In order to enable pleasant washing/showering, both the air and the water are heated.

(11) FIGS. 1-3 show an embodiment of a shower system 20 including a shower stall 22 with a plurality of outlet points for dispensing a heated air stream saturated, or significantly saturated, with miniaturized water droplets (hereinafter “spray”). Water is input to shower system 20 via a water input 104 and may include a water flow meter 103 and a water pump 110 for increasing water pressure. Without limitation to particular droplet size, it is noted that the miniaturized water droplets can be on the order of 50-100 micron droplet size.

(12) As seen in FIG. 1, shower system 20 may include peripheral components such as a solar water heating system with a hot water tank 107; a solar water-heating panel 107a; and a water circulation system 107b, configured to circulate and measure the temperature of hot water. Shower system 20 may interface with a solar powered generation system 109, which includes solar-electric panels 109a for generating electricity. Shower system 20 may also interface a security camera system 105 and may be controlled via a smartphone 106. An electrical connection to the peripheral components may include a bi-directional power meter 108.

(13) FIG. 2 shows shower system 20 including a main shower spray head 201 for delivering heated air, saturated or substantially saturated with water, i.e. a spray 202. Shower system 20 may also include a number of side ports or secondary spray outlets 203 also configured to dispense spray 202. Shower system 20 may also include a flexible spray pipe 206. Additionally, shower system 20 may include lights 208, such as an LED color light, whose color and intensity can be controlled from a control panel/screen 400 (described herein-below). Shower system 20 may also include waterproof speakers 209, which can also be configured as microphones, controllable by control screen 400 for music and phone calls.

(14) FIG. 3 shows the main portions of shower system 20, which may be installed behind shower stall 22 or in the ceiling. Shower system 20 includes an air intake 301, which can be located at the bottom of one of the walls of shower stall 22. An air inlet filter 302 can reduce the amount of humidity entering the system. An air supply fan or blower 303 is operable by an air-blower motor 304 at variable speed and is configured to generate a desired air flow. Two heating mechanisms (individually or in combination) can heat the air: an electric air-heating radiator 305 actuated by an operating switch 316 (or via control screen 400); and a heat exchanger or hot water radiator 306, configured to use hot water from the boiler to heat the air. The temperature of the air can be heated to the desired air temperature, controlled by comparing a desired air-water mixture temperature 401 (FIG. 4) and air temperature as measured by a temperature sensor 324.

(15) From a hot water inlet 307, water flows through hot water radiator 306 to a standard mixing valve 310 operated by two motors: a water temperature mix motor 311, which controls the temperature (i.e. mix of hot/cold water) and a water flow motor 312, which controls the water flow. From a cold water inlet 308, water arrives to mixing valve 310 as well. The hot water inlet 307 has a hot water inlet temperature sensor 313 and the cold water inlet 308 has a cold water inlet temperature sensor 314. Sensors 313 and 314 are used to alert the user and stop operation if the hot water inlet is above a given (dangerous) limit, and usable to control water circulation by a circulation valve 309 and the circulation system 107b. Temperature sensor 313 provides temperature data to panel display/screen 400 (FIG. 4) for efficiency calculations and system malfunction monitoring. A return air temperature sensor 317 is used by the shower system 20 to determine the quantity of air and water heating required.

(16) The controlled water flows into a plurality of shower-water outlet valves 318, 319, 320, 321, directed to hot water fogger nozzles 322 and 323. For example, a four-port shower is shown including: a main water outlet valve 321; two peripheral shower-water outlet valves 318 and 320; and a low flow water outlet valve 319 for flexible spray pipe 206. The water is suspended into the heated air stream by a main fogger nozzle 323 and secondary hot water fogger nozzles 322. The main air-water suspension spray outlet 325 can be angle adjustable as can secondary spray outlets 326. The shower system 20 may include a low flow warm water outlet 327 to supply warm water, for example, for intimate washing or shampooing.

(17) FIG. 4 shows an embodiment where shower system 20 includes a shower control panel/screen 400 that may be used to display the output of security cameras 105 (FIG. 1). The control panel/screen 400 may also be connected to smartphone 106. When entering shower stall 22, the user can select the control panel/screen 400 as a mirror of the user's smartphone and can issue and receive phone calls and other activities as if s/he were using his/her smartphone.

(18) Temperature control is performed in a closed loop by comparing the air-water mixture temperature 401 requested by the user via the operating screen 400 to the temperature obtained by the output of mixing valve 310 measured by mixing valve outlet temperature sensor 315.

(19) Flow control is performed in an open loop by the user's requested hot air-to-water ratio 403 on the operating screen 400, wherein a 100% request opens mixing valve 310 to full open position, and 0% closes the valve completely.

(20) The user interface or screen 400 is typically configured to include the following shower controls: the desired air-water mixture temperature 401 controlled by the temperature selector 402, which may be via a linear control mechanism or a rotational mechanism, a digital mechanism or any other suitable design. The hot air-to-water ratio 403 can be controlled by an air-to-water mix ratio selector 404, which can also be a linear, rotational, digital or other mechanism. A mixed hot air-water outlet selector button 406 activates an air-water sub-screen 406a (FIG. 5) that includes an operating button that opens and closes the water flow at the main air-water mist outlet 325, which cannot be closed, and in peripheral shower-water outlet valves 318, 320. An activation button 405 can be used to activate and close the low flow water outlets 206, 327 via valve 319.

(21) On the control panel/screen 400, below a line dividing between the main shower functions and the panel's other functions, there are various options, selectable by function or set-up buttons 407, 408, 409, 410. For example: a light control button 407 can open a light control screen 407a (FIG. 5) that controls the various lights connected to the shower system 20, including: shower lights 208, which can be controlled by a shower light screen 407b (FIG. 5), operated by a shower key on lights screen 407a, and home lights, outdoor lights.

(22) Smartphone-function button 408 can be used to switch the panel/screen 400 into a “smartphone mirroring” mode 408b (FIG. 6), which is a state wherein the screen shows exactly the smartphone's display and acts as the smartphone. The user can select his name (e.g. Moses, FIG. 6), whereby previous settings for Moses can be used as default or initial settings, and can operate the functions in this mode, for example, to issue and receive phone calls, receive and send text messages, play music and so on, similar to when the smartphone is connected to the car media. Security cameras and related display application can be activated via a security camera button 409. Setup button 410 can be pressed to open one or more screens where other advanced functions can be selected, such as the type of main controls (linear, digital or rotating), and the water saving screen.

(23) FIG. 7 shows a water saving screen 700 that can be accessed via setup button 410 (FIG. 4), then a “water saving” selection. Screen 700 is the water saving screen, one of the setup options, so “setup” 701 and “water save” 702 icons are shown. Screen 700 also shows shower operation time 703, quantity of water consumed 706; and quantity of water saved in liters 704 and in percent 705, relative to a standard shower. The memory function can be reset via a memory function reset button 707, and then the water savings can be displayed from that point on.

(24) FIG. 8 illustrates a hot-air water suspension spray produced by the shower system wherein it is seen and noted that the spray is capable of being sprayed outward to a useful distance whereby the spray can appropriately come into contact with the user. Adjacency or near adjacency of the hot water fogger nozzles to respective spray outlets (e.g. hot water fogger nozzle 322 to spray outlet 326 at a hot air outlet 328), i.e. hot water mixes to form a suspension with the hot air at or at least quite close to the point where the hot air is delivered to shower stall 22, contributes to this desired outward/extended spray formation. This desired outward/extended spray condition is in contrast to where the spray diffuses to the point where the spray does not extend outward to provide for efficient contact with the user.
