14 Claims. (Cl. 4-161) This invention relates to an improved cabinet bath and is directed to a cabinet bath which can provide a steam,

water or hot air bath either individually or alternatively.

The principal object of the present invention is to provide a cabinet bath which is conveniently adaptable as a steam or water bath or hot air bath and in which the user of the bath can control the conditions in the cabinet of the type of bath selected.

According to the present invention a steam, water or hot air cabinet bath is characterised by the provision of a casing body within which a user is adapted to be seated with the neck of the user received in a top opening in the casing, an inclined open front closable by a hinged door to permit access by a user to the interior of the casing, a step formation on said door having manually operable controls thereon for regulating bath conditions in the cabinet, and with arm openings in the door above the step formation to permit access to the said controls by the user from within the cabinet.

The back wall of the'casing forming the cabinet may be arranged to form or support a seat and also to form with the side walls a rear compartment adapted to contain a steam generating unit and/or a hot air generator arranged to direct steam or hot air into the cabinet.

The arm openings are normally closed by hinged doors or flexible sleeves and a hinged lid may be provided to cover the neck opening during storage-of the cabinet. The neck opening lid may be arranged to form a head rest for the user when seated in the cabinet. The steam generator or hot air generator are under the control of adjustable thermostat and time regulators. Valve means within the cabinet may also be provided to regulate water supply to spray nozzles, suitable outlet draingage outlet being provided for the discharge of water collected in the bottom of the cabinet.

In order that the invention may be more readily understood reference will now be made to the accompanying drawings illustrating a steam or water cabinet bath constructed in accordance with the present invention. In these drawings:

FIGURE 1 is a perspective view of the cabinet constructed according to the present invention;

FIGURE 2 is a perspective view of the cabinet with the stepped access door and neck opening door in open positions;

FIGURE 3 is a view in side sectional elevation of the cabinet;

FIGURE 4 is rear elevation of the cabinet showing the steam generating unit and associated piping;

FIGURE 5 is a diagram of the electrical circuit for the control of the steam generating unit heating elements, and

FIGURE 6 is a schematic circuit diagram of a low voltage operated contactor for the steam generator heating elements.

As illustrated in the drawings a steam or water bath cabinet 10 comprises a casing 11 having side walls 12, an inclined front 13 having an opening 14 therein, a relatively narrow top 15 having a neck opening 16 centrally located therein, and a back wall 17 formed of several United States Patent 0 l 3,290,607 Patented Dec. 13, 1966 integral sections adapted to form a seat 18, back rest 19 and arm rests 20 and 21 for a person to be seated within the cabinet. The seat 18 and back rest 19 are also preferably padded as at 22 and 23 respectively, the said back wall 17 also forming a partition to provide a compartment 24 at the rear of the cabinet between the side walls 12 thereof.

The inclined open front 13 is closed by a door 25 hinged at one side of said opening 14 and in the open position permits a person to be seated in the cabinet with their neck received in the neck opening, 16, which latter is preferably provided with a hinged lid 26 adapted to uncover said opening 16 and provide a rest for the head of the person in the cabinet.

The door is provided with a stepped portion 27 the upper surface of which is visible to a person seated in the cabinet and on which portion 27 are located adjustable thermostatic and

time controls

29 and 28 for equipment to be hereinafter described. Two spaced arm holes 30 and 31 are also provided in the door above the stepped portion 27 to permit access by the person within the cabinet to the controls on the door. The arm holes 30 and 31 are closed by hinged

flaps

32 and 33 or flexible sleeve closures (not shown) through which the hands may be inserted.

The steam generator 34 for the cabinet comprises a low pressure boiler comprising a tank 35 located in the rear compartment 24, said tank 35 receiving a supply of water therein from an external supply pipe 36 through a float controlled valve 37 within the tank. If required a water supply pipe 33 is provided in one arm rest 21 to provide a manual supply of water to the boiler tank 35.

Steam outlet pipes

39 and 40 are connected to the boiler tank above the water level therein, said pipes extending into the cabinet on each side thereof at or adjacent to the level of the floor 41 and are perforated to deliver steam into the cabinet. The floor 41 is provided with an inclined section 42 which forms a foot rest for the user of the cabinet.

The water in the tank is boiled by two electric

immersion heating elements

43 and 44 one of higher wattage than the other e.g. 800 and 1600 watts respectively, the higher rated element or both in parallel being connected to a power supply for quick boiling and the lower rated element for maintaining a steam supply from the tank. A water supply valve 45 connected to supply pipe 36 is also provided in the arm rest 20 to control a supply of cold water to a plurality of spray nozzles 46 on pipes 47 located in the cabinet to provide a covering shower for a person seated in the cabinet. Steam condensate or shower water is collected above the floor 41 or at back of seat 18 and is drained ofi through drain pipes 48 for discharge to a waste pipe.

The power supply 49 is connected to the

Water heating elements

43 and 44 in the boiler tank 35 through a control box 50 which includes two conta-ctors in the form of

relay switches

51 and 52 and a transformer 43 arranged to provide a low voltage, e.g. 12 volts, energising circuits for the relays under the control of the time and thermostat controls 28 and 29 mounted on the door 25.

The low voltage circuits for the timer and thermostatic controls are provided as a safety measure so that electrical circuits adjacent to or operated by the user are of such a voltage that any current leakage will not constitute an electrical danger.

As illustrated in FIGURES 5 and 6 the diagrams of the timer and thermostat, heater elements and control box circuits are shown. In these diagrams the timer 28 is a timer switch of known kind and is adjustable to respectively connected to the

heating elements

43 and 44 for the supply of energising current thereto. The adjustable thermostat control switch 29 is also connected in the circuit of relay 51 to control the current supplied to the higher wattage heating element 44 as determined by the temperature setting effected thereto and which will operate according to the steam temperature in the cabinet.

A cut out switch 55 is also associated with the float valve 37 in the boiler tank and is arranged to open the power supply circuit when the water in the boiler tank 35 reaches a dangerously low level above the

heating elements

43 and 44. The cut out switch 55 is actuated by a member 56 which rides on the float valve arm and when a low water level is reached it opens the switch 55 which normally remains closed.

The above described cabinet provides a steam or water spray bath. However, in addition or as an alternative the cabinet may be provided with a hot air generator (not shown) which may consist of a fan adapted to pass air over an electric heating element and the heated air then being ducted into the cabinet. The same or similar timing and thermostat controls may be provided for the hot air generator portion of the air heating element which is cut out or cut in by the thermostat to maintain a temperature within the cabinet as determined by the setting given the thermostat.

Thecabinet may be made of any suitable material such as sheet metal. However, a more suitable material is reinforced synthetic resin which provides lightness as well as heat insulating properties which would prevent excessive heat losses through the walls of the cabinet.

It will be apparent that a steam, water or hot air cabinet bath, as above described, will provide a unit which may safely be operated by the user and provides a convenieut and relatively simple unit which can be economically produced, and safely operated by the user without the necessity of an attendant to control the conditions in the cabinet.
