1. A personal hygiene apparatus for patients with reduced mobility, comprising:
a support casing,
a removable tank for washing water,
a housing formed on the casing, the housing accommodating the removable tank,
a grippable washing head comprising at least one delivery mouth and a flow alternating chamber connected to the at least one delivery mouth,
a pump,
a hydraulic circuit connecting the tank, the pump and the washing head with each other, the hydraulic circuit comprising a bi-directional delivery duct and a recirculation duct, the bi-directional delivery duct configured to allow the washing water to flow in a first direction and a second direction, and
a valve assembly in the hydraulic circuit;
wherein the apparatus provides for a working operation mode and a standby operation mode, wherein the valve assembly:
in the working operation mode, determines in the hydraulic circuit a water supply path for the washing water from the tank, to the pump, through the bi-directional delivery duct, through the flow alternating chamber of the washing head and finally out of the at least one delivery mouth; and
in the standby operation mode, determines in the hydraulic circuit a water recirculation path for the washing water from the tank, to the pump, through the recirculation duct, through the flow alternating chamber of the washing head, through the bi-directional delivery duct and finally back to the tank, without washing water flowing out of the at least one delivery mouth, wherein the pump is in continuous operation during the working operation mode and the standby operation mode such that, during the working operation mode, the washing water flows in the first direction through the bi-directional delivery duct and, during the standby operation mode, the washing water flows in the second direction through the bi-directional delivery duct.
