1 Claim. 1
The present invention relates to new and useful improvements in refrigerated cases of the type in wide-spread use in stores and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character comprising novel means for preventing moisture in the surrounding air from condensing on the usual window thereof.
Other objects of the invention are to provide a moisture condensation preventing means of the character described which will be comparatively simple in construction, durable, compact and which may be manufactured at low cost.
All of the foregoin and still further objects and advantages of th invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a perspective view of a refrigerated display case equipped with the present invention;
Figure 2 is a vertical sectional view, taken substantially on the line 2-2 of Figure 1;
Figure 3 is a fragmentary view in horizontal section, taken substantially on the line 3-3 of Figure 1; and
Figure 4 is a detail view principally in vertical longitudinal section, showing the connection between the blower and the air pipes or conduits.
Referring now to the drawing in detail, it will be seen that reference numeral 6 designates generally a refrigerated display case comprising a cabinet I having a window 8 in the front thereof, said window including spaced glasses III, II, etc., as usual. The top 9 of the cabinet 1 includes a forward extension which is formed to provide a shade or shield l2 for one or more fluorescent lamps 13.
A mechanical refrigerating unit at one end of the cabinet 1, said a housing l having formed in its a chamber or compartment of an electric motor driven air intake openings partment l6.
Extending horizontally adjacent the upper and lower portions of the outer glass in of the window 8 and in front thereof are upper and lower air distributing pipes l9 and 20, respectively. The air pipes I9 and are connected at one end to the outlet 2| of the blower I! by a coupling 22. In the embodiment shown, and as illustrated to advantage in Figure 4 of the drawing, the coupling 22 comprises a plug 23 which is secured in the blower outlet 2| by screws 24.- The plug 23 has formed therein threaded openings which accommodate the pipes l9 and 20, as at 25.
The other ends of the pipes 19 and 20 are closed I4 is provided unit including upper portion l6 for the reception blower l1. Suitable iii are provided for the comby plugs 26 (see Figure 3). At spaced points the pipes it and 2t have formed therein longitudinal slots constituting air discharge ports 21. The ports 2? are arranged to direct streams of air over the outer surface of the front glass I 0 of the window 8.
It is believed that the operation of the invention will be readily apparent from a consideration of the foregoing. Briefly, the blower l1 draws air from the room or atmosphere into the compartment I6 through the intake openings l8. The compartment I 6 is warmed by heat generated in the unit It, thus raising the temperature of the air in said compartment. The warmed air is driven by the blower I! through the pipes IQ and 2t and is discharged in streams over the outer surface of the front glass ll] of the window 3 in a manner to prevent moisture from condensing thereon. The lamp shade l2 conceals the upper air pipe 19. The shield 28 on the cabinet 7 substantially conceals the lower air pipe 2i].
It is believed that the many advantages of a refrigerated display case constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention.
Having described the invention what is claimed as new is:
In combination, a refrigerated display case including a window, a mechanical refrigerating unit comprising a housing including a chamber in its References Cited in the file of this patent UNITED STATES PATENTS Number Name Date 2,462,705 Abeling Feb. 22, 1949 2,542,136 Hanson Feb. 20, 1951 2,558,997 Voelker July 3, 1951
