According to one embodiment, a sensor device includes a transmitter part, a receiver part, a signal generation part, and a determination part. The transmitter part is configured to emit a radio wave outside as a transmission wave. The receiver part is configured to receive a reflection wave reflected by an object as a reception wave. The signal generation part is configured to generate a first output signal generated based on the transmission wave and the reception wave, a second output signal provided with a phase different from that of the first output signal, and a third output signal generated based on the first output signal and the second output signal. The determination part is configured to determine presence or absence of an object based on the first output signal, the second output signal, and the third output signal.

An economical and effective process for the complete removal of soap scum and dirt from surfaces such as those in showers and bathtubs without any scrubbing has been defined. This patent application defines cleaning devices that make the said process easy, practical, and automated. The said devices employ the previous referenced process and ultimately eliminates the chore of cleaning the showers and bathtubs.

The present disclosure provides a descaling apparatus of an electronic toilet bidet, the descaling apparatus comprising: a descaling liquid storage tank comprising a descaling liquid chamber configured to house descaling liquid, wherein a pressure element is disposed and movable in the descaling liquid chamber, wherein the descaling liquid chamber comprises a descaling liquid outlet, wherein the descaling liquid storage tank further comprises a main body liquid outlet fixedly connected to and in communication with a bidet liquid inlet of the electronic toilet bidet, and wherein the main body liquid outlet is configured to be controlled to connect or disconnect the descaling liquid outlet. The descaling apparatus according to the present disclosure may supply the descaling liquid automatically and continuously to the internal pipes of the electronic toilet bidet for several times after the descaling liquid is added at one time.

A system for centrally controlled sanitization of a lavatory of an aircraft using ultraviolet (UV) light includes a first UV light source configured to emit a first UV light, and a second UV light source configured to emit a second UV light. The system further includes a central controller coupled to the first UV light source and the second UV light source and configured to independently control the first UV light source and the second UV light source to emit the first UV light and the second UV light at least one of at different times or for different durations.

The invention relates to a bidet/toilet combination (1) comprising: —a toilet bowl (2) surrounding a bowl space (3); —a spray device (4) comprising a spray nozzle (5) located in the bowl space (3); wherein the spray nozzle (5) is arranged and designed to adopt a rest position (6) and a use position (7). The invention also relates to a method for operating said toilet and to the use of said bidet/toilet combination.

A compact spraying device (10) connectable to a surface and for spraying a fluid comprises a housing (16) with an inlet (20), a pump (28) in fluid communication with the inlet (20), a retractable nozzle (24) in fluid communication with the pump (28), a nozzle cover (22) and a drive system (30). The retractable nozzle (24) selectively extends forward relative to a front side of the housing (16) into a spraying position for spraying the fluid and retracts inside the housing to a retracted position when not spraying. The nozzle cover (22) is selectively moveable from a closed position in which the cover (22) covers the nozzle (24) when the nozzle (24) is in a retracted position, to an open position in which the cover (22) moves to allow the nozzle (24) to extend into the spraying position. The drive system (30) moves the retractable nozzle (24) and the nozzle cover (22) and operates the pump (28).

Implementations of a self-cleaning toilet cleaner are provided. In some implementations, the self-cleaning toilet cleaner may comprise a housing, one or more reservoirs, a toilet opener, one or more exterior brushes, and one or more bowl brushes. In some implementations, the self-cleaning toilet cleaner may also comprise one or more lid brushes, one or more seat brushes, one or more fluid lines, and one or more fluid pumps. In some implementations, the self-cleaning toilet cleaner may also comprise one or more blowers, one or more operation pads, one or more operation motors, one or more sensors, and a computer system.

In some implementations, a method of using the self-cleaning toilet cleaner may comprise receiving a toilet into the self-cleaning toilet cleaner, cleaning one or more portions of the toilet with the respective brushes, and applying a fluid to further clean the portions of the toilet. In some implementations, the method may also comprise applying a fluid to rinse the one or more portions of the toilet, drying the one or more portions of the toilet by blowing air on the portions with the blower, and releasing the toilet from the self-cleaning toilet cleaner.

Modules, systems and methods that disinfect surfaces using ultraviolet (UV) light are disclosed. In one aspect, a UV light-emitting module comprises an enclosure including a rear wall and a face plate that includes a light-transmitting aperture. At least one sidewall extends between the rear wall and the face plate, and at least one UV light emitter is located within the enclosure. The module includes at least one cooling feature selected from (1) a sidewall ventilation opening in the at least one sidewall and (2) a heat sink feature extending from the rear wall.

Assemblies and methods for disinfecting surfaces using ultraviolet (UV) light are disclosed. In one aspect, a UV light-emitting assembly comprises a plurality of UV light emitters, and first and second UV light emitter supports seating the UV light emitters. A first heat sink is affixed to the first UV light emitter support and a second heat sink is affixed to the second UV light emitter support. A thermally conductive and electrically insulating plate contacts the first heat sink and the second heat sink.

The object of the present invention is a urinal apparatus fitted, in particular, with a special connection to which a duct is connected in order to extract the aerosol generated during its use, by means of an electric exhaust unit that expels the aerosol outside the bathroom, thus preventing it from being diffused inside the room.
