Ap lication May 10, 1941, Serial No. 392,929
This invention relates to health cabinets, and more particularly to a cabinet for health treatments wherein there is maintained a circulation of warm, moist air for the stimulation of perspiration.
It is an object of this invention to produce a health cabinet within which there is maintained an air circulation and in which means are provided for maintaining the air heated and humid.
Another object of this invention is to produce a health cabinet in which a person is adapted to be confined and within which means are pr0- vided for maintaining a definite air circulation and for maintaining moisture in the air as it is circulated.
Another object of this invention is to provide a health cabinet in which means are provided for maintaining a circulation of warm, humid air where the circulation maintained over the individual within the cabinet and where the circulation passes over the shoulders of the individual back of the individual and around over the front of the individual.
Another object of this invention is to provide a health cabinet in which there is mounted a water tray and in which means are provided for passing heated air over the surface of the water in the tray and for directing a continuous circulation of the air over an individual positioned Within the cabinet.
C ther objects and advantages of this invention it is believed will be apparent from the following hereinafter contained description of a preferred embodiment thereof as illustrated in the accompanying drawing.
In the drawing:
Figure 1 is a perspective View partly in section of the health cabinet embodying my invention.
Figure 2 is a fragmental sectional side elevation thereof.
Figure 3 is a horizontal section of the air circulating heating means embodied in my invention.
Figure 4 is a wiring diagram of the heating and circulating means embodied in my inven tion.
Figure 5 is a fragmental sectional elevation of the modified form of health cabinet embodying my invention.
In the preferred embodiment of my invention -"1 as illustrated in the accompanying drawing, I indicates a platform which is supported on wheels 2 to provide a mobile unit. Secured to the rear of the base I is a rear partition or plate 3 having an upper plate 4 secured thereto at the upper end. Secured to the forward end of the base i is a front plate 5. Curved ribs 6 define the upper extremities of the side walls I and the top surface of the cabinet. Any suitable material may be utilized for forming the side walls I and the front closure 8. As herein illustrated, canvas duck is stretched between the edges of the base plate I and the ribs 6 and extends over the front face 8. The duck is slit at the slits 9 and H), which slits 9 and I0 terminate in'a neck aperture H. The duck is joined at the slits by the use of suitable fastening means such, for example, as those commonly referred to as zippers.
Hand apertures l2 are formed in the duck to permit the hands to be thrust out of the cabinet. An arm sling I3 is mounted within the cabinet in order to support the arms.
Mounted on the base plate I is a chair l4 having a supporting partition [5 which extends transversely of the chamber within the cabinet. The chair It is provided with a back If) suitably curved and which terminates short of the sidewalls 1. The back I6 is also positioned forwardly from the rear partition or plate 3 so as to provide an air passage 11.
Mounted upon the base plate I to the rear of the partition I5 is an air circulating fan I8 which directs air through ducts l9 into an air heating chamber member in which there is mounted a water pan 2|. Mounted in the chamber member 20 below the water pan 2| is a heating element 22. The air outlet from the chamber member 20 is provided with a bafile member 23 having bafile wings 24 which tend to direct the air as circulated along the inner surface of the side walls 1 toward the front of the cabinet as indicated by the circulation arrows 25. The air thus circulates up over the individual seated upon the seat I 4 and passes up over his shoulders as indicated by the arrows 26, passes down through the air channels I! and back into the circulating fans l8.
The fans or blowers I8 include the housings 21 and blades 28 mounted upon the motor shafts 29 of the electric motor 30. The ducts [9 are connected over the outlets of the housings 21.
Any suitable or desirable form of heating unit 22 may be employed and the power for operating the motor 30 and the heating elements 22 is derived from the power means 3|, the leads from which are suitably coupled to the motor 30 and the heating element 22.
Mounted in the circuit is an electric clock switch 32 of any suitable or desirable form as is well understood in the art, which may be set to control the supply of current to the motor 30 and heating elements 22 for the desired period of time and then cut out the operation of both the circulating motor and the heating elements 22.
The heating elements 22 are suflicient to supply the heat required for maintaining the air circulated at the desired temperature and the heat is supplied to the water in the water pan 2!. The circulation of the air by the blowers l8 over the surface of the water so takes the heat away from the water as to maintain the same at a relatively low temperature. The effect is that the relative humidity within the treatment chamber is maintained at approximately 45% with air temperatures between 120 and 130 F.
Of course both the temperatures and relative humidity are subject to variation, dependent upon the rate of circulation of the air and the temperature, by maintaining a relatively high velocity of air over the water in the pan 2!. The water in the pan, however, is maintained at the relatively low temperature so that very little evaporation of water occurs and as the individual within the cabinet perspires, the perspiration of the inwhich is shaped to fit over a register 40 through which hot air from any suitable or desirable source is supplied, ordinarily for the purpose of heating the room. The duct leads through the rear partition 3 and the water pan 2 I is mounted in the duct. The reduced end M of the duct provides the means for directing the circulation. The circulation duct is provided with an opening 42 through which air from within the cabinet passes on its circulation to again pass over the surface of the water in the pan 2|. modification of my invention, as there is continuously introduced heated air from the register 40, it is essential to provide outlets 43 from which air may pass from within the cabinet in order to maintain the described circulation.
The neck apertures H and H are ordinarily closed through any suitable means such as by wrapping a towel around the neck of the individual positioned within the cabinet for treatment, the head of the individual protruding from the cabinet.
The front closure or face of the cabinet is inclined upwardly from the front panel member 5 The principal In this i to the upper edge of the rear panel or partition 3 and as thus inclined, serves to confine the direction of travel of the air within the cabinet.
Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my invention is of the full scope of the appended claims.
