DETAILED DESCRIPTION OF THE INVENTION The solution according to this will now be described with the help of drawings. invention. The present invention relates to a power supply system for household appliances. designed to reduce electricity usage costs and promote the use of clean energy. The system comprises a portable solar panel 1 that converts sunlight supplied through solar rays 10 in electrical energy, which can be used to charge a power station 6 or a storage battery 3. The power station 6, once charged, can be connected to a 2 appliance via a connection cable specific 8, allowing the appliance 2 to operate partially with the energy stored in the power station 6 or in the storage battery 3. The appliance 2 is also equipped with a seat 7 to house the battery. storage 3, which supplies energy via an inverter 4 that converts the current continuous alternating current usable by the appliance 2. The management of the power source is entrusted to an electronic board 5 which monitors the level charging of the storage battery 3 or the power station 6 and switches automatically powering appliance 2 to the mains power of the house via a connection made with a 9 plug when the energy stored in the power station 6 or in the storage battery 3 is sold out. The electronic board 5 can be integrated into the appliance 2 or external. This system allows the appliance 2 to operate partially with clean energy, reducing bill costs and contributing to the protection of the environment. On days when charging via the portable solar panel 1 is not possible (for example for cloudy or overcast skies), the electronic board 5 ensures that appliance 2 uses only mains power of the house via a connection made with a 9 plug. In particular, the hybrid power supply system provides power from the mains electric via a 9 connection and an alternative auxiliary power supply provided from a power station 6 or a storage battery 3, 3a, in which the power supply alternatively it is rechargeable via a portable solar panel 1. In Figures 1 and 2, reference 1 indicates a portable solar panel for generate electrical energy thanks to the solar rays indicated with the reference 10. The The panel is portable to be placed outside the home and is orientable to receive the greatest possible amount of solar rays 10. An appliance (in this case a washing machine is represented) is indicated with the reference 2. Of course the appliance can also be a dishwasher, a dryer etc. Referring to Figure 1, an example of “direct” power supply is shown in which Solar panel 1 powers appliance 2 directly via a power supply station 6 and a specific connection cable 8. In Figure 1 the reference 11 indicates a display to show the progress of the wash cycle. On display 11 is You can also see the current power type of the appliance 2. On the contrary, Figure 2 shows an example of “indirect” power supply in where the solar panel 1 powers the appliance 2 via a storage battery 3 which is previously loaded and then subsequently used for power the appliance 2. The storage battery 3 is recharged via a charging device not shown. The storage battery 3, once charged, it can be inserted, for example, into a seat 7 located on the appliance 2. Alternatively, as illustrated in Figure 6, appliance 2 may have a battery 3rd fixed inside the appliance structure 2 which can be recharged via a charging plug 13. With reference to Figure 3, a solar panel 1 is illustrated which, thanks to the rays solar panels 10 recharge a storage battery 3 and via an inverter device 4 supplies energy to the appliance 2. Figure 4 shows an example of a solar panel 1 with a support arm 12, for positioning the solar panel 1 so as to receive the solar rays 10. In this example the panel can be movable or a panel can be foreseen fixed, but orientable so as to accumulate the greatest quantity of solar rays 10. With reference to Figures 5 and 6, examples of household appliances 2 are illustrated with the auxiliary power indication. In particular, in the case of external battery 3 (Figure 5) the location of the battery 7 for battery housing 3 charged by solar panel 1, the inverter 4 and an electronic board for managing the appliance's power supply 2. In particular, in the case of fixed battery 3a (Figure 6) the battery 3a is illustrated which is charged via the charging plug 13, the inverter 4 and a board electronics for managing the power supply of the household appliance 2. This invention aims to reduce the costs of electricity usage household appliances, thanks to a solar panel 1 dedicated to the appliance 2. As visible in Figures 5 and 6 there is space to accommodate the battery fixed 3a is the removable rechargeable battery 3. Also in other household appliances it is there is space to house the battery for auxiliary or alternative power. Then using a portable solar panel 1 irradiated outside the house From the solar rays 10 you can charge a power station 6 or a storage battery 3. In case a power station 6 is used, once charged by solar rays 10, it is sufficient to connect it via a specific connection cable 8 to the appliance 2 to ensure that a part of the appliance functions 2 occurs using clean energy provided by power station 6 and subsequently, once the energy supplied by the power station 6 has run out, the appliance 2 switches to use the home current supplied by the electrical grid via cable 9. The electronic board 5 decides when to use the energy provided by the power station 6 or the house current via connection 9 to the home network. Always thanks to a portable solar panel 1, you can recharge a battery of accumulation 3 which battery, once recharged, is inserted inside the seat special 7 obtained in the appliance 2. Thanks to an inverter 4, clean energy is then supplied to the appliance 2 for to be able to function. The electronic board 5 manages when to use the current supplied by the battery 3 or the house current via connection 9. Once the appliance program 2, storage battery 3 must be removed from seat 7 and recharged by solar rays 10 via solar panel 1. As mentioned, appliance 2 can alternatively also have a fixed battery 3rd within its structure, a bit like what happens with electric cars. On days when it will not be possible to recharge via solar panel 1, the battery 3 can remain in seat 7 and the electronic board 5 will only use the current of the house via connection 9 to operate appliance 2. In the case of the fixed 3A battery, on days when it will not be possible to recharge via solar panel 1, electronic board 5 will only use the current of the house via connection 9 to operate appliance 2. In this way it is possible to have an appliance that can partially function thanks to clean energy, reducing bill costs and doing good to the environment. The present invention also relates to a household appliance 2 equipped with a system hybrid powertrain and a modification kit to make a hybrid powertrain power supply as described.
