This invention relates to improvements in air conditioning devices of the type which employ a chemical substance for changing the condition of the surrounding atmosphere.
The general object of the invention is to provide a device for positioning an air treating chemical substance in exposed relation with the surrounding atmosphere in places where it is desired to condition the air, such as in cellars, vaults, clothes closets, containers, or even an entire room or building, which device consists of an outer receptacle and a holder for receiving the chemical substance which is adapted to be selectively mounted relative to the receptacle whereby the substance may be initially enclosed in a substantially airtight manner and whereby it may be quickly and conveniently exposed to the surrounding atmosphere.
A further object of the invention is to provide a device for containing a chemical substance having moisture absorbing properties which includes a container and a holder for the substance which are so arranged that the substance may beenclosed in the container in a substantially airtight manner when not in use and when desired it may be conveniently and quickly exposed to the surrounding atmosphere to attract moisture from the atmosphere and to deliver excess accumulated moisture into the container.
A more specific objector the invention is to provide a water receiving receptacle having an aperturedcover member and a desiccant containing holder which is adapted to be secured to the receptacle by the cover member in one position in which the desiccant is enclosed in a substantially airtight manner and in another position in which the desiccant is exposed to the surrounding atmosphere and excess moisture attracted by the desiccant will be accumulated in the receptacle.
A further object of the invention is to provide a water receiving receptacle having a reversible cover member and a desiccant container attached at one end to the cover member whereby when the cover is placed on the receptacle in one position the desiccant is enclosed within the container and when the cover is reversed and then placed on the receptacle the desiccant is exposed to the surrounding atmosphere and wherein a temporary sealing member is initially removably secured on the receptacle cover when the cover is placed on the receptacle with the desiccant in the enclosed position.
Another object of the invention is to provide in a device of the character described a convenient means for selectively increasing the exposure of the moisture absorbing material to the surrounding atmosphere and thereby regulate the absorbing rate of the device.
A further object of the device is to provide in a device of the character described means where. by the device may be readily filled with a fresh supply of the moisture absorbing material or ad.- ditional material may be readily added as desired.
While the invention is particularly adapted for use with a chemical substance for dehydrating or dehumidifying the atmosphere in a room or the like it is also effective for use with substances for fumlgating, scenting, deodorizing, etc, which it may be desirable to retain in an airtight manner and at times expose to the atmosphere.
Other objects and advantages will appear hereinafter from a description of the preferred forms of the invention which are shown by way of illustration in the accompanying drawings wherein:
Fig. 1 is a sectional elevation of an air treating device embodying the principles of the invention, the holder for the chemical substance being on closed within the outer receptacle and being shown in elevation with portions broken away;
Fig. 2 is an exploded elevational View of the device with the chemical holder partially with.- drawn from the outer receptacle;
Fig. 3 is an elevational view showing the chemical holder supported on the top of the outer receptacle;
Fig. 4 is a view similar to Fig. 1 showing a modified form of the device;
Fig. 5 is a partial elevation of the device shown in Fig. 4 with parts broken away, the chemical holder being mounted in exposed position;
Fig. 6 is a sectional elevation of a further modified form of the device; and
Fig. 7 is an elevation of the device shown in Fig. 6 with parts broken away, the chemical holder being mounted in exposed position. I
Referring to Figs. 1 to 3 of the drawings, the preferred form of the device comprises an outer imperforate receptacle or container l0 and a chemical receiving container or holder member II which is adapted to be selectively secured in a completely enclosed position within the receptacle It or in a completely exposed position above the same.
The outer receptacle it! which is illustrated as tubular in form may be any desired shape. and may be constructed of glass, metal, plastics, paper or any other suitable material. The receiptacle H3 is provided with a relatively Wide open mouth l2 formed by the neck l3 which is with an open mouth 3!.
threaded to receive a threaded metal retainer ring 14 having a relatively narrow inwardly directed flange [5.
The chemical holder Il may be formed of wire screen, perforated sheet metal or any similar material which i capable of holding or retaining a chemical substance such as calcium chloride, silica gel or the like in crystalline or cake form. The body of the holder member H is preferably the same form as the outer receptacle it and is somewhat smaller in cross section. It may be flanged at its ends Or provided with reinforcing members is for greater trength. The base or bottom end of the holder II is mounted on a supporting disk i? which is provided with perforations IS. The holder H is preferably rigidly secured within a flanged ring l!) which is rigidly secured to the disk ii. The top or freeend of the holder it is provided with a removable cap member 2d. The cap 28 which may be attached to the holder l i by a simple friction fit as shown, or by a screw threaded'connection, is illustrated as a flanged ring 2i having a perforated surface 22 formed of wire screen or similar material. It may also be formed from a s'ngle piece of imperforate material. The removable cap 23 is provided so that the holder H may be filled with the chemical substance from the free end. As an alternative construction the free end of the holder ll may be permanently closed by either a perforated or imperforate member and the base end of the holder may be removably connected to the supporting disk ll. The supporting disk ii is of the proper size to fit within the retainer ring it and when positioned. against the top of the receptacle ill may be clamped thereto by the flange i5 of the ring it. A disposable imperiorate disk member 23 is provided for positioning between the flange l5 and the supporting plate ii to seal the receptacle l0 when the holder ii is initially positioned within the same.
The device is adapted to be initially assembled as shown in Fig. l with a charge of the chemical substance in the holder H and with the sealing disk 23 clamped in position over the perforated plate ll by means of the retaining ring it. When it is desired to use the device, the metal retaining ring id is removed and the sealing disk 23 is disposed of. The plate H and the holder H are removed from the receptacle it. After being inverted, the disk ii is repositioned on the top edge of the receptacle it and clamped in position thereon by replacing the metal retaining ring hi, the central aperture in the ring it being sufficiently large to accommodate the holder l l which projects above the receptacle Iii. When the chemical substance within the holder H is a desiccant such as calcium chloride, the moisture in the surrounding atmosphere is absorbed by the calcium chloride forming the liquid hydrate which drips down through the solid desiccant as deliquescense and into the outer receptacle l6 where it remains until it can be conveniently removed. Any moisture running down on the outside surface of the holder ll is directed within the holder H by flanged ring Hi which provides a relatively small circumferential pocket 24 (Fig. 3) between the same and the perforated wall of the holder.
A modified form of the device is shown in Figs. i" and 5. The outer receptacle St is similar to the receptacle it shown in Fig. 1 and is provided The chemical holder 32 is similar to the holder ll shown in Fig. l and is permanently secured to the supporting plate 33 by a flanged ring 34. The plate 33 is formed of perforated material and is secured to an intermediate flange 35 on the retaining ring 38. The retaining ring 36 is reversible having a threaded outer extension 31 which is provided with a temporary sealing disk 38 may be of any suitable material and is attached to the outer edge of the retaining ring portion 31 in any suitable manner to provide a substantially airtight seal when the ring 36 is initially secured on the receptacle 3B. The free end of the holder 32 is provided with a removable cap 39 similar to cap 20 shown in Fig. 1.
An additional feature of this form of the device which is equally applicable to the other forms illustrated consists of a removable covering material of paper or the like which initially surrounds the perforated chemical holder 32 and which is weakened or perforated along the lines 46 and 4! to divide the material into strips 52 which may be successively torn off and removed to expose as much of the perforated surface of the holder 32 as desired when the holder 32 is exposed to the atmosphere. 7
This form of the device is used in the same manner as the preferred form illustrated in Figs. 1 to 3. The retaining ring 36 is removed from the outer receptacle 3i) and the sealing disk 38 is separated from the same and discarded. The ring 35 is inverted and the extending portion 31 is replaced on the mouth 3| of the outer receptacle 3a to pos-tion the holder 32 (Fig. 5) in the exposed position in contact with the surrounding atmosphere.
A further modification of the device is illustrated in Figs. 6 and '7. This form of the device is particularly adapted for very economical manufacture. The tube-like outer receptacle 59 is preferably of paper or similar relatively cheap material. The chemical holder 5| is formed of any suitable perforated material and is secured to the supporting plate 52 which is preferably perforated. The holder 5! is provided with a removable closure cap 53 on the free end. The
outer receptacle 58 in either the position shown in Fig. 6 with the chemical holder 5i disposed within the outer receptacle 5% or in the position shown in Fig. 7 with the chemical holder 5| supported in exposed position. A sealing cap 53 is provided for initially closing the top of the retaining sleeve 55 (Fig. 6). V
In using this form of the device the sealing cap 58 is removed and the sleeve 55 is withdrawn from the outer receptacle 5E1. After being inverted, the sleeve 55 is repositioned on the receptacle 5%} with the chemical holder 5| extending upwardly therefrom in exposed position.
In all of the illustrated forms of the invention, the. holder for the chemical substance is attached at one end to a supporting disk or similar 7 disk or plate 38. The
rated from the outer receptacle. The sealing disk may be permanently disposed of if it is the type illustrated in Figs. 4 and 5 or it may be retained with the device if it is the replaceable type illustrated in Figs. 1 to 3, 6 and 7 in the event that it is desired to reposition the chemical holder within the outer container and reseal the same therein.
