The present invention provides a fluid injection system (11) which transitions between a maintenance mode wherein an outlet (15) is closed and no fluid is discharged through the outlet, and an operation mode, wherein the outlet is open and fluid is discharged through the outlet. The fluid injection system injects a first fluid transported in a first pipeline (21) with a second fluid, wherein there is a temperature differential between the first fluid and the second fluid. The fluid injection system comprises a holding tank (49) for storing the second fluid, a cooling means (35) to cool the second fluid, and a pump (39) for delivering the second fluid into the first pipeline. The second fluid mixes with the first fluid in the first pipeline to provide a combined third fluid having a temperature within a predetermined temperature range, wherein the third fluid is maintained within the predetermined temperature range when the fluid injection system is in either mode such that the temperature of the third fluid made available to an outlet is within the predetermined temperature range.

A soaking-device is usable to soak a given body part of a user. The body part may be a face or a portion of the face of the user. The user may be a person or other animal. The soaking-device includes a vessel-subassembly. The vessel-subassembly includes a wettable-subassembly. The wettable-subassembly itself and/or interaction of the wettable-subassembly with a part of the vessel-subassembly, its outermost-shell, may not utilize screws or the like mechanical fasteners. The wettable-subassembly may include a neck-gasket for removable physical contact with a neck portion of the user. The wettable-subassembly is configured to hold a volume of an immersion-liquid for the soaking of the body part. Prior to use, the volume of the immersion-liquid may be heated or cooled. A breathing-apparatus may be used. A tower may be placed next to the wettable-subassembly to shine light into and/or to release bubbles into the immersion-liquid.

A soaking apparatus suitable for use in a shower, wherein the apparatus comprises a reservoir for holding water. The apparatus may comprise at least one rotomolded part. A soaking chair comprising: a bucket seat comprising a seat back, a seat surface, and two armrests; and a support structure; wherein the chair is suitable for use in a shower; and wherein the seat surface comprises a reservoir.

Disclosed is a skin washing apparatus using a brushless DC motor, including: a case for the skin washing apparatus; an operation unit installed outside the case, for commanding an ON/OFF operation of the skin washing apparatus and an switching operation for forward and reverse rotations in unit of a predetermined angle; a brushless DC motor installed inside the case to be operated by electric power received from the power supply so as to be rotated forwardly and reversely in unit of a predetermined angle; a control unit for outputting an electrical signal for controlling forward and reverse rotations of the brushless electric motor by a predetermined angle in response to a switching signal of the operation unit; and a skin washing brush mounted on a shaft of the brushless electric motor to be rotated forwardly and reversely according to an operation of the brushless electric motor.

A personal hygiene capsule has a housing. a toilet. at least one spray nozzle. a drain provided in a lower portion of the housing. and at least one scrub brush operably mounted to wash at least a portion of an occupant of the personal hygiene capsule. Methods of using the personal hygiene capsule are provided.
