This invention relates to health cabinets and more particularly to a cabinet wherein there is maintained an uninterrupted circulation of moist, warm air.

It is an object of this invention to provide a health cabinet of limited vdimensions and which is substantially fully enclosed and within which an individual may be seated and within which the air is heated, circulated over a pan of heated water, and forced to circulate in a direction so that the heated air will iirst pass over the upper portion of the body of the person receiving the treatment and will be returned downwardly over the person in the seated position and will return for recirculation.

Another object of this invention is to provide a health treating cabinet in which the air within the substantially enclosed cabinet is under continuous forced circulation over a pan of heated water and within which cabinet there is a substantial division' or separation so that the circulation is maintained and wherein the air laden with water is circulated in a direction to first pass over the body of the person within the cabinet at the upper portion of the body and to follow the body downwardly during its circulation.

This invention is directed to an improvement over the health or humid air cabinet as set forth in the patent issued to me December l, 1942, No. 2,303,465.

Other objects and advantages oi this invention it is believed will be apparent from the following detailed description of an embodiment thereof as illustrated in the accompanying drawings.

In the drawings Figure l is a side elevation partly in vertical section of the health cabinet embodying my invention,

Figure 2 is a top plan view thereof partially in horizontal section, taken on line 2--2 of Fig. 1.

Figure 3 is a sectional View taken substantially on the line 3 3 ci Figure l.

Figure 4 is a sectional end elevation illustrating the health cabinet of my invention as positioned Within a bath tub.

Figure 5 is a top plan View partly in horizontal section of a modied form of construction embodying my invention.

Figure 6 is a side elevation partly in vertical f section of the structure as illustrated in Figure 5.

In the form of my invention illustrated in Figures l to 4, inclusive, the cabinet is composed of a frame I which may be made of any suitable or desirable material and the frame l includes a base` plate 2, spaced vertically extending side Walls 3 and 4, and appropriately curved foot and head sections 5 and (i. The side walls 3 and il are formed as illustrated in Figure 4 of stepped construction to provide shoulders i and 8 by which the frame may be supported upon the rims Q of the bathtub le with the bottom plate 2 raised from the bottom ll of the tube it. A top plate i2 which extends over the foot section (i completes the frame structure. Over this frame structure there is stretched, to complete the enclosure, a fabric top it. The -fabric top i3 is divided on a diagonal line and is normally closed by means of a suitable fastener indicated at iii which may be of the type o a Talon fastener.

The fabric covering is provided with an opening i5 which is adapted to extend around the neck of an individual seated upon the chair ifi Within the enclosure when the -fastener is closed, thereby completing the enclosure. Formed through the base plate t are a plurality of drain openings l'i which Permit the draining of water or moisture from within the cabinet into the bathtub l0 and hence through the drain outlet i8 thereof.

In order to permit the entire health treatment to be given without the necessity of the individual getting out of the cabinet, a shower head I9 is mounted with reference to the cabinet so that when the treatment within the cabinet is concluded, the fastening i il may be opened and the shower head brought over the individual so that the patient -may be given a shower within the cabinet without being exposed to the varying temperatures which would be occasioned by getting out of the cabinet. The patient therefore may take the shower while still in position upon the seat l' and the water would drain through the opening il and out through the bathtub drain i8.

In the proper heat treatment of the individual within the cabinet, I have found that in order to obtain uniform or even distribution of the heat, that it is preferable that the air within the cabinet be circulated continuously in the cabinet in such manner that the air after it has been heated and has picked up the requisite quantity of moisture by passing over a pan of water be circulated upwardly within the cabinet so as to rst engage the individual receiving the treatment at the upper portion of the body and then be circulated downwardly over the person within the cabinet passing over the feet and legs thereof and then be returned for recirculation. In this manner the heat transmitted to the body from 3 the heated air and moisture content thereof is more evenly distributed when care is taken to maintain continuous circulation of the air withm out permitting formation of dead air pockets within the cabinet from which there is no circulation.

I have further found that circulation within such a cabinet can only be induced and maintained by proper division of the cabinet through the use of a partition as will enable a circulating means to draw air through an outlet in the partition and freely discharge the air within the cabinet in a direction where the discharge does not encounter an obstruction which will result in the formation of a back pressure. Therefore, in accordance with my invention as the same is illustrated in Figures 1 to 4, inclusive, the seat I6' of the chair I6 extends horizontally across the entire enclosure and is supported upon the legs 20 in position elevated from the base 2. The back 2I is connected with the seat I6 and likewise extends for the full seat of the enclosure and is supported at its upper end by spaced bars 22 which are connected with the rear section 6,

Extending from the rear of the seat I6 and to the rear section is a partition 23 which partie tion has an air inlet 24 formed therein and at one side of the cabinet, the opening 24 being of substantially the same size as the inlet 25 formed in the housing 26 of the circulating fan 21 in which the inlet 25 is formed in a vertical partition 28 at the side of the structure opposite that of the inlet 24. Between these inlets there is formed a chamber 29 by means of the enclosing partitions 30. Within this chamber there is mounted a water pan 3|. The water pan 3l is supported upon a plate 32 which has an openingf 33 formed therein. Below the opening 33 there is positioned an electrical heating element 34 of the infra red hot-wire type.

The fan 21 is driven by an electric motor 35 which is housed within an enclosing housing 35i secured to the rear section 6 and exterior to the enclosure formed within the cabinet so that the motor 35 may operate within the colder air outside of the cabinet.

It will be observed that the side walls 3 and 4 slope from the top plate I2 downwardly to the relatively short front section and lie closely adjacent the seat I6', thereby leaving a very small space within the cabinet through which the air is circulated.

It will be observed that the back 2| is formed with two spaced openings 31 through which air from the mixing chamber 33 formed above the fan 21 passes. These openings are formed at the sides of the chair back so that the heated air will pass around the body of the person seated upon the chair I6.

With the patient upon the chair IIB and the fastening I4 closed, the motor 35 and heating element 34 are set in operation. The air is drawn by the fan 21 from the chamber 29 above the water pan 3l. Air from below the chair I6 is drawn through the partition 23 through the opening 24 therein and passes in the direction of the arrows 39 (Figure 3) over'the surface of the water within the pan 3l, evaporating water from the pan and this heated moisture-laden air then passes through the fan 21 and into the mixing chamber 38 where the moist air is thoroughly mixed before it passes out through the openings 31 and over the top of the chair back 2I. The air then follows in its forced circulation draWIl over the body of the person seated upon the seat I6 following the curved inclination of the closure formed by the fabric top elements I3 down over the legs and feet of the individual and then passes in the direction of the arrows 40 (Figure 1) under the chair I6 and is again recirculated. As this moist air is recirculated, it deposits moisture upon the individual and the combination of the hot air and the moisture quickly heats the body of the person upon the chair I6. As the air deposits its moisture, it continues to pick up further moisture from the water within the pan 3I until a point is reached where the body is sufliciently heated to cause the same to perspire after which substantially no further water is evaporated from the pan 3l. The depositing of the hot moisture upon the body in combination with the hot air, quickly raises the temperature of the body to the point of perspiration.

In the modified form of my invention illustrated in Figures 5 and 6, the structure is substantially the same as hereinabve dened with he exception that the cabinet herein illustrated is of the portable type not adapted for mounting within a bathtub and the circulation unit is mounted below the chair and the air is drawn horizontally from withunder the chair rather than vertically from within the space provided to the rear of the chair.

In this modification similar parts have been indicated by similar numerals with the addition of an exponent a thereto and the structure differs essentially in that the dividing partition 23a extends vertically across the cabinet under the seat Ia of the chair Ita, and the water pan Ela, and heating element 34a. are mounted under the chair in advance of the partition 23a while the fan 21a, motor 35a and eduction conduit 39a aremounted upon the rearward side of the partition 23a.

In this modification the water pan is withdrawn from under the chair so that it may be filled with water while in the modiiication of Figures 1 to 4 the water pan is withdrawn from the side of the rear section 6a from the exterior of the cabinet. In other respects the structure is substantially similar as is the method or circulation.

In the modication of Figures 5 and 6 the air passes under the chair I 6a in the direction of the arrows 40a, passes over the water within the pan 3 Ia down around the heating elements 34a which likewise act to heat the water in the pan 3Ia, out through the conduit 30a, which provides a mixing chamber 29a, and into the inlet 25a formed in the fan housing 26a. The air is exhausted by the fan vertically to the rear and back of the back 2Ia of the chair I 6a over the top of this back and through the openings 31a formed therein and circulated downwardly over the individual seated upon the seat I6a and under the fabric covering I3a and it is returned for circulation.

It will be observed that in the modiiication of Figures 1 to 4 that there is provided a curtain 4I which is carried upon a common form of curtain roller 42. When the cabinet is opened for the purpose of permitting the person receiving the treatment to take a shower, this curtain is drawn over the seat back 2| so as to prevent the spray of Water passing into the mixing chamber 38 and hence into the fan, etc.

The structure of the cabinet as herein dened lends itself admirably for fabrication to a molded plastic construction so that the entire framework may be constructed of any desired color of plastic material which lends itself to the producing of a very desirable structure.

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.
