s claims. 1
My invention relates to improvements in moisture removing devices for domestic type deep freezers.
As explanatory, deep freezers for household use and other purposes, equipped with top lids frequently accumulate moisture on the top and lids which freezes and glues the lids shut, if such moisture is not frequently removed by wiping ofi the same, or simila.. procedure.
With the foregoing in mind, it is the primary object of my invention to equip such freezers with means of simple form and inexpensive construction whereby moisture on the top and lids will be removed and the closed lids maintained dry so that the lids will not freeze shut, and the drudgery of having to Wipe the top and lids dry at frequent intervals to prevent such freezing of the lids wil be obviated.
To the accomplishment of the above and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing setforth in detail in the succeeding description, and defined in the claims appended hereto.
In said drawings:
Figure 1 is a view in side elevation of a deep freezer equipped according to vmy invention and partly broken away to show the internal mechanism thereof;
Figure 2 is a view in plan;
Figure 3 is a view in perspective of the moisture remover detached.
Referring to the drawing by numerals, my invention has been illustrated therein as forming part of the equipment of the usual box type deep freezer I having near one end 2 and side 3 a bottom chamber 4 for a motor 5 driving a fan 6 for blowing air through the usual refrigerant condenser coil I and out of louvers 8 in said end 2 near the bottom of said end, such air being taken into the chamber 4 through a grill 8 on said side of the freezer I to be forced through the chamber 4 and out to the atmosphere through the louvers 8 to cool the motor 5, fan 6 and said coil 1. Such freezers are provided with hinged top lids, as at 9, which easily become glued shut by moisture freezing on the top I of the freezer around said lids.
According to my invention, as illustrated, a moisture remover in the form of an air deflector shell II is provided at the louver equipped end 2 of the freezer l for deflecting Warm air issuing from the louvers 8 over the top I0 and lids 9 to keep the same dry by drying up moisture tending to accumulate on said top in the manner specified.
The air deflector shell II is preferably semito the sides 3 of said freezer I by apertured edge ears I5 on the end walls I3 secured to said sides 3, as by screws I 6. The deflector shell I I projects at its open side I4 above the top I0 of the freezer I to provide a discharge opening II extending from front to back of the freezer clear across said top and at the top of said shell. The circumferentialv wall I2 is extended past the end walls I3 to form a ledge I8 projecting forwardly over said opening I'I to direct air issuing from said opening over the top I0 and lids 9 of said freezer.
The operation of .my invention will be readily understood. 'Ihe warm air blown out of the chamber 4 and the louvers 8, under pressure by the fan 6, discharges into the deflectors I2 and is deflected by the circumferential wall I I thereof upwardly and out of the opening I1 over the top I0 and lids 9 of the freezer I whereby said top and lids are maintained dry by quick evaporation of moisture accumulating thereon. As will be clear, this positively obviates the objectionable feature of having the lids 9 freeze or glue shut and also the objectionable feature of having to wipe the top and lids clean of moisture.
The foregoing will, it is believed, suffice to impart a clear understanding of my invention, without explanation.
Manifestly, the invention, as described, is susceptible of modification, without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.
Having described my invention, what is claimed as new is:
1 The combination with a deep freezer having a top lid. a condenser coil compartment with an outlet adjacent the bottom and in one vertical wall thereof, and means for discharging air under pressure out of said outlet, of means for deflecting such discharging air upwardly to the top of said freezer having a discharge opening extending across said top from one side of said freezer to an opposite side and in a plane perpendicular to said top. whereby such air is discharged along said top and lid to remove moisture from the same.
2. The combination with a deep freezer having a top lid, a condenser coil compartment with an outlet adjacent the bottom and in one vertical wall thereof, and means for discharging air under y across said top from one ing such discharging air upwardly to the top of said freezer having a discharge opening extending across said top from one side of said freezer to an opposite side and in a plane perpendicular to said top, whereby such air is discharged along said top and lid to remove moisture from the same, said means comprising 4a shell having an open side opposed to the first mentioned vertical side of the freezer oversaid outlet, said shell extending above said top with a part of its lopen side above the same.
3. The combination with a deep freezer having a top lid, a condenser coil compartment with an outlet adjacent the bottom and in one vertical wall thereof, and means for discharging air under pressure out of said outlet. of means for deecting such discharging air upwardly to the top ofsaid freezer having a discharge opening extending side of said freezer to 4 an opposite side and in a plane perpendicular to' said top, whereby said top and lid same, said means open side opposed side of the freezer over said outlet,said shell eitending above said top with a part of its open side above the same, said shell being oi' substantially semi-cylindrical shape with a circumferential wall curving from said outlet over the top of the such air is discharged along to remove moisture from the comprising ashell having an freezer to deflect the warm air over said top.
