- the generator also comprises two level sensors arranged in the tank, these sensors not being shown in the figure. They are located at two levels of the tank, designated as the minimum and maximum levels of liquid in the tank.
- the minimum level generally corresponds to the level in which the ultrasonic transmitter is just covered with water, the heating resistance being then also covered with water.
- the maximum level is a level above which the tank may overflow through an overflow pipe, for example a level corresponding to 80% of the total capacity of the tank. Filling the tank to this level, as will be seen later, also cleans the overflow area.
- the generator also includes two temperature sensors.
- the first temperature sensor is constituted by a temperature probe for measuring the temperature of the liquid in the tank 22. This probe is arranged in the tank and is not shown in the figures.
- the second temperature sensor 28 forms a safety sensor, such a sensor being here a bimetal comprising two metal blades of different thermal coefficients welded together. Such a sensor makes it possible to send an electrical signal when the temperature exceeds a threshold temperature.

- the resistance control circuit also includes a clock, the operation of the switch or switches can also be performed according to the data received from the clock.
- the process begins in a step 100 when the clock indicates a predetermined time, this time being one hour during which the device does not work by spraying the liquid on the consumables, for example at night at 2 o'clock in the morning.
- the method is indeed implemented when the spray heads are deactivated and do not work. Products can be absent.
- the supply means of the liquid tank are actuated during a step 102 of filling the tank.

- the filling is stopped and the heating resistor 26 is supplied to start a step 106 for heating the liquid contained in the tank.
- a step 108 of actuating the generator pump is also triggered to allow the cleaning liquid to circulate in all the elements of the tank. Circulating the liquid in the tank makes it possible to heat the tank more evenly.
- the tank level is determined if the level of the tank is below a predetermined level corresponding to the low level thereof, in a step 110.
- step 110 If the level determined in step 110 is lower than the predetermined level, the heating and circulation of the liquid in the tank is stopped and the process is restarted at step 102 for filling the tank.

- the temperature of the liquid is maintained in a predetermined range around 70 ° C, for example the range of 68 ° C to 72 ° C.
- step 112 if the temperature is lower, however, than predetermined temperature, it is verified in a step 114 that a predetermined time is not exceeded using the clock.
- the predetermined time is, for example, 2:45 because it has been determined that operation of the cleaning process during a 45 minute cycle may be sufficient to eliminate biofilms and bacteria, when the predetermined temperature is a temperature of 70 ° C.
- the process is returned to steps 106 and 108 and the pump and heating resistor continue to be operated.
- the process is terminated during a step 116, and all the members of the tank such as the heating resistor or the pump are stopped.
- the liquid used to clean the generator is also removed.
- This emptying can be done using a gravity drain valve connected to the sewer, for example. The emptying takes place via a conduit which is not part of the droplet diffusion circuit in the receiving zone and which communicates directly with the tank
- the execution of the end step 116 could also be controlled by detection by the bimetallic safety sensor of a temperature greater than its threshold temperature.
- the sensor threshold temperature is chosen higher than the predetermined temperature so that it does not trigger the end step of the process if the probe operates correctly. However, it allows to stop the process in the case where the probe is defective and where the temperature of the liquid is too high. Its threshold temperature may in particular be 85 ° C., and is determined by the holding temperature of the ceramics and other components of the circuit in contact with the superheated liquid.
- the device can resume normal operation.
- liquid is diffused into the reception zone. This diffusion takes place without this liquid having been previously heated in the tank until reaching the predetermined temperature, and even without this liquid having been heated beforehand in the tank.
- the liquid remains cold, at ambient temperature and / or at its temperature at the outlet of the water supply network, the latter being able to be higher or lower than the ambient temperature.
- the device has had time to cool completely since cleaning before resume operation as a diffuser in the reception area.
- the device comprises a temperature probe and that after cleaning, the tank is filled with cold water. If the temperature of the water is below a predetermined threshold, for example at 25 ° C, the nebulization resumes on the receiving zone, otherwise it may be necessary to redo the drain and at least one other filling cold water . It is this cold water that cools the system. This characteristic also makes it possible to control that the temperature of the water does not exceed the threshold in normal operation also.
- a predetermined threshold for example at 25 ° C
- This process begins at an initial step 200 during which the start of the process is operated by an operator from the outside, for example in the morning before the opening of the store.
- the tank is filled with liquid during a step 202, similar to step 102, and then the level of the water is determined in a step 204, similar to step 104.
- step 202 of filling the tank is continued.
- the filling is stopped and the heating resistor is electrically powered to perform a step 206 for heating the liquid contained in the tank.
- a step 208 the temperature is then measured using a temperature probe and it is determined whether the temperature is above a predetermined temperature, that is 70 ° C in the present case.
- a timer is triggered during a step 210. During this time, the liquid is heated. It may be possible to reduce the power of the heating resistor once the timer has been triggered.
- a step 212 it is measured whether the time from which the stopwatch is switched is greater than a predetermined period, for example 5 minutes, which is a sufficient time to eliminate the bacteria by pasteurization when the liquid is raised to 70 ° C.
- step 212 If the measured time is less than 5 minutes, return to step 212 and measure the elapsed time again.
- the tank is emptied by means of an evacuation means thereof such as a pipe connected to a drain valve giving onto the all-to-one in a step 214. It also controls the shutdown of the heating resistor.
- a step 216 it is determined whether it is the first emptying performed.
- the method is returned to the filling step 202 and steps 202 to 216 are performed again.
- the time interval between two cleaning cycles can advantageously be evaluated according to the actual operation of the machine. It has been verified that the ultrasound system with acoustic concentrator was effective in destroying bacteria. On the other hand, a long period of non-operation or partial power operation favors the development of biofilms. The cycle will be more frequent when the device will be used at reduced power. Moreover, during a restart after a long period of shutdown, the water of the filters may be more or less contaminated, it is then necessary to rinse the filtration and proceed with an initial heat shock to ensure the quality of the water. 'water.
- the pump has a high water flow rate in comparison with the flow of the diffusers 24.
- the pump has a flow rate of 2 liters per minute and the broadcasters collectively have a flow rate of 1, 6 liter per hour, these values not being limiting.
- the ratio between these flows, namely that of the pump on that of the diffusers, is 75. This means that the pump constantly brews the water much faster than the water is nebulized. This results in a dilution effect of the bacteria in the bath.
- the bacteria content is therefore low at each moment in the diffusers so that the nebulizing action effectively ensures their destruction, from the beginning of operation, thanks to the bactericidal effect of ultrasound. This content will of course be reduced as cleaning progresses.
- the ratio above is greater than or equal to 50, and preferably it is at least 60.
- the device includes a fan for the diffusion of the air carrying the droplets of nebulized water, it will be preferable to keep it stopped during the cleaning so as not to dissipate the heat produced by the resistance.
- the device and method are not limited to what has been described above.
- It can thus comprise a single level sensor, that of high level, or no level sensor at all, the end of the filling can then correspond to the end of a predetermined time.
- a device according to the invention may not include a pump or may comprise a number of spray heads different from that described.
- the process may also be different from what has been described.
- the method according to a first embodiment can be triggered manually, and not automatically using a clock.
- steps 104, 108, 110 are optional. It is also not necessary to empty the tank of the liquid once it has been cleaned even if it is more hygienic.
- the method may include a waiting step for a suitably selected predetermined period of time before stopping the filling and starting the heating of the liquid, the duration being preferably chosen so that the cleaning liquid does not overflow the tank.
- a suitably selected predetermined period of time before stopping the filling and starting the heating of the liquid, the duration being preferably chosen so that the cleaning liquid does not overflow the tank.
- the method according to the second embodiment may also be different from what has been described above. It can for example be performed once and not twice, even if the cleaning is then less good. It can also be done more than twice, if the cleaning needs to be even more efficient.
- the method according to the second embodiment can be controlled by a clock as in the method according to the first embodiment of the invention and be triggered at a given time. Steps 204, 208 and 216 are also optional. The method according to the second embodiment of the invention can also be performed entirely automatically.
- the method comprises a servocontrol of the heating device at temperature, as is the case in the first embodiment of the method.
- temperatures, levels, durations or periodicities indicated are not limited to those described above.
- the method of the invention can be implemented by choosing a relatively high predetermined temperature, for example greater than 80 ° C or 90 ° C, such as 100 ° C.
- a relatively high predetermined temperature for example greater than 80 ° C or 90 ° C, such as 100 ° C.
- the device and method according to the invention can also be used for cleaning ducts for spraying consumables.
- the orifices of these conduits can be plugged and the filling can be controlled so that the cleaning liquid also fills them.
- the device comprises a pump that can circulate the liquid in a closed circuit in the tank and the conduits.

- nebulize hot water on the receiving zone with the device for example water having a temperature of up to 60 ° C.
- this temperature level may damage the nozzles so that it is preferable, in such a case, to limit the duration of nebulization of the hot water to 10% of the total operating time in nebulization on the zone of reception.
- the tank is filled with cold (clean) water at room temperature and / or at the temperature of the network. feed it comes from, water that is immediately flushed through the dedicated conduit to properly rinse the device and that there is no residue of biofilm, bacteria, etc.
- This filling and emptying is carried out at least once. Then, the following filling is used for normal operation for nebulization on the reception area. This rinsing also has the effect, if necessary, to cool the tank and the device before the resumption of nebulization.
