Definitions
- the invention relates to the field of showers.
- the invention belongs to installations for collecting water and for supplying water for domestic purposes. More precisely, the invention concerns a so-called cyclic shower, which reuses water leaving a clean water circuit and becoming gray water.
- cyclic showers include numerous equipment in addition to the basic equipment of a classic shower (head, collection tray, hose, temperature adjustment device, drain plug). [9] This poses two problems: the first concerns the ergonomics of the cyclic shower.
- the equipment of a cycle shower can be bulky and may require modifying many of the basic equipment of a traditional shower. This approach is not satisfactory from an ecological point of view
- showers such as those disclosed by document DE4124605A1
- a washing head such as those disclosed by document DE4124605A1
- a basin to collect the washing water, which will be sucked by a pump into a pipe.
- These showers also include a water heater between the pump and the wash head to heat the circulating wash water. This water heater helps compensate for heat loss from circulating wash water.
- these showers have the disadvantage of not providing the same temperatures of clean water and gray water leaving the circuits.
- the shower, as disclosed may lack robustness in the event of a power outage.
- the present invention aims to remedy all or part of the disadvantages of the state of the art cited above.
- the present invention relates to a cyclic shower.
- This cyclic shower comprises two independent water circuits, a first circuit called clean water, configured to be connected to the drinking water network, comprising a first outlet, and a second circuit, called gray water, comprising a second outlet and configured to receive and circulate water from the first and second outlets.
- first outlet we mean an outlet configured to let clean water out outside the first circuit. This water, once it has left the first circuit, can be used by a user of the cyclic shower in order to wash themselves.
- second outlet we mean a water outlet configured to let gray water out outside the second circuit. This water, once it leaves the second circuit, can also be used by a user of the cyclic shower in order to wash themselves.
- Gray water is considered to be water that has left the first circuit or the second circuit, through the clean water or gray water outlet. Thus, the water circulating in the second circuit is considered gray water.
- clean water network is meant a conventional network, for example domestic, comprising a means of heating clean water such as a water heater and means of distributing heated water and untreated water. heated. Clean water can be drinkable.
- the clean water circuit includes a temperature control system configured to allow the user to choose a set temperature of the clean water, the temperature control system being configured so that the clean water first outlet is at said set temperature.
- this temperature adjustment system comprises a button or a lever or any other element configured to be manipulated by a user.
- the temperature control system comprises a thermostatic mixing valve configured to be connected to a hot clean water inlet and to a cold clean water inlet.
- the cyclic shower also includes a water recovery tank coming from the first and second outlets as well as a pump connected to the second circuit and configured to reinject said water from the recovery tank into the gray water circuit.
- the cyclic shower may include a gray water filtering system arranged in the second circuit.
- the filtering system prevents the passage of certain particles into the gray water circuit such as hair, solid pieces of soap as well as other finer particles.
- the filtering system thus makes it possible to limit the risks of congestion in the gray water circuit and damage to the gray water circuit equipment.
- said filtering system comprises a strainer positioned in the gray water circuit. The strainer helps prevent particles such as hair, fur and solid pieces of soap from entering the gray water circuit.
- the filtering system comprises at least one filter, which is positioned in the gray water circuit. It is preferably positioned downstream of the strainer.
- the filter(s) prevents the passage of particles larger than 5pm into the gray water circuit. It helps improve the level of cleanliness of gray water.
- the filter has a water inlet configured to allow gray water upstream of the filter to fill the filter and a water outlet, configured to allow exit gray water from the filter, after passing through said filter, said filter comprising an automatic drain configured to allow filling of the entire filter with gray water, whatever the position of the water outlet from the filter and to extract the gray water from the filter at the end of use of the second circuit.
- This embodiment has the advantage of allowing the filter to be drained at the end of use of the second circuit without user action. This prevents water from stagnating and therefore the development of bacteria within the cyclic shower.
- the cyclic shower can include, in a particularly advantageous mode, a disinfection module, configured to disinfect the gray water before it leaves the gray water circuit.
- Said disinfection module is configured to have a bactericidal, germicidal and virucidal action on the gray water circulating in the second circuit. It preferably eliminates bacteria, germs and viruses. It can remove 99.999% of viruses, bacteria and germs from water.
- the disinfection module preferably comprises a UV lamp configured to irradiate the gray water circulating in the second circuit with UV radiation.
- UV radiation allows the elimination of the aforementioned viruses, bacteria and germs.
- the UV lamp is preferably at least one UV LED, LED being the English acronym for “light emitting diode”, or in French “electroluminescent diode”.
- the UV lamp traditionally has two states: off and on. This has low power consumption compared to other UV lamps such as LPHO (English acronym for “low pressure, high output”, or in French “low pressure, high output”) and robustness in the face of changes in temperature. off and on states of the UV lamp.
- the UV LED can be turned off and on several times within a time interval of around ten minutes, and maintain its performance in terms of eliminating viruses, bacteria and germs. This corresponds to a classic use of the cyclic shower by a user.
- the cyclic shower also includes a water heater configured to heat the gray water, and a thermal control device configured to control the water heater so as to maintain the gray water at, substantially, the set temperature of the clean water.
- the thermal monitoring device is also configured to extract the set temperature.
- This cyclic shower has the advantage of offering a cyclic shower with two independent water circuits, allowing the same temperature of the gray water and the clean water throughout the use due to the fact that the gray water is heated to the same temperature as the clean water which, compared to a classic cyclical shower, avoids using additional clean hot water to heat the gray water which would have cooled, thus limiting the consumption of water.
- the adjustment of the temperature of gray water and clean water is carried out by a single instruction from the user of the set temperature, which reduces the number of manipulations of the latter. when using the shower and therefore makes it easier to use.
- the cyclic shower is resilient to electrical or electronic failures: such a failure does not prevent the operation of the clean water circuit.
- This cyclic shower advantageously allows the same temperature of the clean water and the gray water at the first and second outlet, while limiting the use of clean water. It is important to differentiate between the set temperature of the clean water and the actual temperature of the clean water, the set temperature allowing continuous information to control the water heater, whether or not there is flow at the within the clean water circuit. Thus, the set temperature is more reliable information to transmit than the actual temperature of the clean water.

- the electronic sensor can be circular and have an exterior diameter of approximately 7 centimeters, an interior diameter of less than 4.6 centimeters and a thickness of less than 0.6 centimeters. It may have a volume of less than 16 cm3.
- the sensor is compact enough to be integrated behind a shower screen when the cyclic shower has a wall. It can also be configured to be integrated into a shower column.
- This configuration is particularly advantageous because, in addition to the small footprint compared to another cyclic shower having more sensors and temperature adjustment systems than said configuration, it makes it possible to reuse classic equipment from a classic shower, at namely a thermostatic mixer, preferably rotary.
- the thermal monitoring apparatus comprises a flow sensor positioned upstream or downstream of the water heater and configured to measure the flow rate of gray water in the second circuit and a temperature sensor configured to measure the temperature of the gray water leaving the water heater, said sensors being configured to control the temperature of the water heater.
- the thermal control device thus makes it possible to obtain gray water heated more precisely to the set temperature because it takes into account the temperature of the clean water and the flow rate of the gray water.
- the thermal monitoring apparatus comprises a flow sensor configured to measure the flow rate of water from the gray water circuit and two temperature sensors, a first temperature sensor being configured to measure the water temperature of the gray water circuit upstream of the water heater, a second temperature sensor being configured to measure the water temperature of the gray water circuit downstream of the water heater.
- the thermal control device has the advantage of having a very precise and more responsive control than the control of an embodiment comprising only a single flow sensor and a single temperature sensor.
- the second sensor allows the thermal control device to know the exact temperature of the gray water leaving the water heater and thus to readjust the temperature of the water heater if the temperature measured by the second sensor is not close enough to or equal to that of the set temperature.
- the cyclic shower comprises a shower column and the thermal control device, the filter(s) as well as the water heater are integrated into said shower column.

More precisely, the float 221, when the quantity of gray water 600 contained in the automatic drain 220 is greater than said predetermined threshold, activates a piston which blocks the air inlet 222 of the automatic drain 220.
- the gray water 600 is evacuated by the automatic drain 220.
