C'GOLING 7- Application filed. June 15,
" .,'llhis invention relates to a device for controlling the temperature of the interior of a building or vehicle.
An object of the invention is the provlsion of a device for not only cooling or warming the air in a confined space such as a room,
the interior of an automobile, or the interior of a railroad coach but for purifying the air at the same time.
A further object of the invention is the provision of a device which will contain a cooling compartment embraced by tortuous air passages through which air is drawn whereby the air will be cooled, such air being 15 taken from a confined space and passed through the device so that a circulation of air is obtained in the space.
A still further object of the inventionis the provision of a device having a cooling 20 chamber embraced by tortuous air paths through which the air is drawn, with a medicator or purifier at the intake end of the device whereby the air is treated before it is drawn through the tortuous path.
l'his invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specification; nevertheless, it is to be understood that the an invention is not confined to the disclosure,
being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.
In the drawings:
Figure 1 is a longitudinal vertical section of the device taken along the line 1-1 of F i gure 2,
Figure 2 is a horizontal section of the de- 40 vice,
v Figure 3 is a transverse vertical section taken along the line 3-3 of Figure 1, Figure 4 is an end view in elevation, Figure 5 is a longitudinal vertical section taken along the line 5-5 of Figure 2,
Figure 6 is a vertical section of a modified form of the device,
Figure 7 is a horizontal section of the device shown in Figure 6,
50 Figure 8 is a transverse vertical section HEATING nnvrcn 1931. Serial No. 5%,607.
taken along the line 88 of Figure 6, and Figure 9 is a vertical section of an air cleaner and purifier.
Referring more particularly to Figs. 1 to 5, inclusive, 10 designates a base member upon which is mounted a rectangularly-shaped housing 11 having a central compartment 12 which is adapted to be filled with ice and salt or the so-called dry ice. \The walls of the central chamber 12 provide longitudinal paths at opposite side walls of the chamber. The centrally disposed chamber 12 is open at the top and is closed by a lid 13 having a handle 1% for readily manipulating the lid.
It will be noted from an inspection of Figure 1 that in the longitudinal air passages upon opposite side walls of the central chamber 12 are located a plurality of alternately disposed baffles 15 and 16. The baflles 15 depend from the tops 17 and 18 and fall short of the depth of the housing 11 to provide air spaces 19 between the lower edges of the baflies 15 and the bottom 20 of the housing 11. The alternately disposed bafiles 16 are secured to or formed integrally with the bottom 20 and fall short of the height of the housing to provide spaces 21 so that the air traveling along these longitudinal passages will pass alternately beneath'the bafiles 15 and above the bafiies 16.
The space 22 at one end of the housing 11 is also divided by a plurality of spaced bafiies 23 and 24:. The baffles 23 are secured to the bottom 20 of the housing 11 while the bafies 24 depend from the top portion 25 of said housing so that a tortuous path is provided for air which is drawn from a room as will be presently explained.
A space is also provided between the end wall 31 of the chamber 12 and the end wall 32 of the housing 11 where the air is drawn in by a fan 33. The space is provided with a pair of bafiles 34 which are secured to the bottom 20 of the housing 11 and terminate short of the top 35 so that air passing under the baflles 15 in the longitudinal passages will rise and pass over the top of the baflies 34 before said air enters the passages 36 of the exhaust housin 37 The exhaust ousing, as shown more particularly in Figures 1 and 2, embraces the exhaust ports 38 and includes a fan housing 39 which is open, at 40 to the interior of a room.
The exhaust housing is provided'with an inclined bottom 41 which is supported by a pedestal 42 upon the base member 10. A motor housing 43 is included within the exhaust housing 37 and the motor 44 is directly cou pled with the fan 33.
An air intake 45 is rectangular in shape and has four imperforate walls which are received within an opening 46 in the rear wall 47 of the housing 11 in such a manner that approximately one-half of the air intake extends within the space 22 within the housing 11 while the remaining portion is projected outwardly from said housing. The outer open end of the air intake is provided with ,a screen 48 through which the air must pass for the removal of dust. The inner end of the intake is also provided with a screen, as shown at 49, which likewise aids in completing the removal of dust in the air. Interme diate the opposite ends of the air intake is provided a medicator 50 which is in the shape of a cross and this medicator may be formed of an suitable material which is sufliciently absorbent to retain the medicant' for the purpose of purifying the air which is drawn through the intake 45.
The operation of the device shown in Figures 1 to 5, inclusive, is as follows: The device is made in a compact form in order that it will take up little space and may be relatively small but nevertheless efiicient. The fan 32 is driven by the motor 44 which is connected to the usual house current or to the battery of an automobile so that when a switch (not shown) is closed, the fan will be driven pulling air in through the tortuous paths upon the opposite side walls of the chamber 12 and through the air intake 45. It will be noted that this device is not connected with the exterior of a building for taking in outside air but is placed within a room, a sedan or any other enclosed space and the air from the room or enclosed space is drawn in through the intake, purified and cooled as the air is drawn through the tortuous paths upon the opposite sides of the cooling chamber 12. This chamber is maintained at a low temperature due to the melting of the ice located in said chamber.
While I have shown a separate container for the ice and salt it will be appreciated that the most convenient method of handling the ice and salt and likewise the water and the residue from the melted ice, is to fill a separate container 71 with the ice and salt and place it within a, chamber 12. e
The form shown in Figures 6 to 9, inclusive, are identical with that shown in F1 ures 1 to 5, except that the end bafiies 24 on y 'are omitted and heaters and 61 are placed in the end spaces of the housing 11 so that when the air is drawn in through the intake 45 it will pass over the heaters before it travels beneath the baflles 23a. This heated air is then carried along through a tortuous path in the longitudinal passages between the side walls of chamber 12 and the side walls of the housing 11a. This heated air then passes beneath the bottoms of the battles 34a. This air is then withdrawn from the space 30 through the passages 36 past the fan 33 and thence into the room.
If desired a tank of hot water may be placed within the chamber 12 instead of the ice which is used for cooling purposes.
A switch 7 0 controls the electric circuit to the heaters so that when a cooling medium is placed in the container or chamber 12 the heaters may be cut off while the fan 33 is being driven. v
I claim:
1. A device of the character described comprising a housing, a receptacle centrally located in the housing and providing longitudinally disposed air passages between the side walls of the housingiand receptacle, a top covering the space between the receptacle and housing, baflles depending from the top of the housing in the air passages and terminating short of the bottom of said housing, alternately disposed bafiles extending upwardly from the bottom of the housing and terminating short of the top, said baflies providing tortuous passages for the air, means for drawing air through the passages, means for affecting the temperature ofthe air drawn through the passages, one end of the housing having an opening, and an air purifying means in the opening and providing an intake for the air.
