Provided is a nursing-care device capable of easily moving a care-requiring person from the nursing-care device to medical/nursing-care equipment arranged at the side of a bed. One embodiment of the present invention includes a bed body having a floor portion at an upper surface, one and the other support bases supporting both ends of the bed body, support rods extending upward of the floor portion, and a lifting/lowering unit configured to lift/lower the bed body and the support rods. A lifting member is attached to the support rods. The support rods are lowered in a case where the bed body is lifted by the lifting/lowering unit, and are lifted in a case where the bed body is lowered. In a case where the support rods are lowered, the lowermost portion of the lifting member is moved to below the floor portion of the bed body.

The present invention relates to a bathing robot device which: can perform the bathing, washing, cleaning, drying, skin caring, disinfecting, or sterilizing of an object; can use technology such as electronic control, artificial intelligence, or IT to autonomously perform corresponding functions without depending on only manpower; and can interact/communicate with an external device. The bathing robot device performs functions of: in a state in which the object is fixed without moving at one position, cleaning or washing the object by spraying water and a cleaning agent to the object; sensing ending of the cleaning or the washing, and drying the object by blowing air; and then, if necessary, spraying a lotion, a medicine, etc. Further, the bathing robot also performs a function of washing and drying an external device such as an object transfer device or a bathing table.

The subject of the present invention is a sauna storage heater and a sauna cabin which uses the sauna storage heater. The sauna heater can be operated independently in terms of energy without a connection to the power grid and without the use of fuels such as wood, gas, or oil. A heat storage fluid is used in the sauna storage heater, the boiling temperature of which fluid is over 100° C. at normal pressure. The heat output from the sauna storage heater is regulated by means of flaps on air inlet and air outlet openings.

A bath system comprises a tub and a fluid injection system. The tub has a jet orifice, and the fluid injection system is fluidly coupled to the jet orifice. The fluid injection system comprises a conduit, a heat source, an air supply source, and a fluid injector. The conduit has an opening. The heat source is coupled to an outer portion of the conduit external to the opening. The air supply source is fluidly coupled to the conduit, and is configured to provide a flow of air to the central opening. The fluid injector is configured to provide water to the flow of air to produce a combined flow of air and water. The heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the opening before the combined flow enters the tub through the jet orifice.

A liner for use with a basin to contain a liquid features a plurality of bodies of flexible plastic. Portions of an inner face of a first body of flexible plastic are joined to corresponding portions of an inner face of a second body of flexible plastic, through which a plurality of openings are formed, to provide a multi-layer body of flexible plastic. Other portions of the inner face of the first body of flexible plastic are not joined to corresponding other portions of the inner face of the second body of flexible plastic, defining an air conduit between the first body of flexible plastic and the second body of flexible plastic for guiding pressurized air substantially from an air discharge apparatus.

A pool or spa system includes networked pool or spa devices that can be dynamically configured with network addresses by a controller. The controller can transmit a device discovery request on a network and can receive a discovery response from pool or spa devices that require a network address. The system determines and assigns the network addresses for the pool or spa devices based on unique device identifiers associated with the responding pool or spa devices. The network addresses assigned to the pool or spa device are transmitted to the pool or spa device to be used by the pool or spa devices to communicate with the controller over the network. The system can be used to discover and assign addresses to various types of pool or spa devices, such as pumps, underwater lights, chlorinators, water feature controllers, remote controllers, and/or other types of devices.

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.

Hot tubs are disclosed herein that include a rigid outer shell having at least two seats formed therein and a footbed below the at least two seats. The at least two seats are either positioned equidistantly from the footbed or at unequal distances from the footbed. The hot tub includes at least two pumps and each pump is configured to pump water to a single seat. The hot tub has an equal number of seats and pumps as well as a skimmer positioned on a sidewall of the rigid shell. The skimmer extends at least one foot in a vertical direction and is configured to supply water to the pumps when a water level in the hot tub is as low as sixteen (16) inches from the footbed and when the water level in the hot tub is at least thirty (30) inches from the footbed.

A walk-in hot tub which can enable one or more users to walk into and out of a hot tub in a dry state may include a hot tub compartment. The hot tub compartment may have a hot tub compartment interior. A tub transfer compartment may be disposed adjacent to the hot tub compartment. The tub transfer compartment may have a transfer compartment interior. An openable transfer compartment door may provide walking access to a user from outside the tub transfer compartment into the transfer compartment interior of the tub transfer compartment. An openable hot tub compartment door may provide walking access to one or more users between the hot tub compartment interior of the hot tub compartment and the transfer compartment interior of the tub transfer compartment.
