UNITED STATES PATENT OFFICE 'REFRIGERATION APPARATUS Orland H. Yox simer, Mansfield, Ohio, assignor to Westinghouse Electric & Manufacturing Company, East Pittsbur Pennsylvania gh, Pa., a corporation of Application September 11, 1942, Serial No. 458,045 Claims. (01. 62-89) My iii'vention relates to refrigeration apparatus slightly ventilated container which is set in the food-storage compartment. of the refrigerator.

Such a hydrator maintains a high humidity in itsinterior but is not readily accessible. The second and preferred type of hydrator is the suspended type, wherein the hydrator receptacle slides from beneath a cover on suitable rails. The suspended typ has the advantages of accessibility and is usually .positioned to provide for good air circulation about its exterior and, therefore, suflicientlyv low temperatures in its interior. However, in order to provide forease of sliding and to allow for variations and warpage of the hydrator receptacle, large clearances on the slides and, therefore, between the cover and the.re-'

ceptacle have been provided. This results in air circulation from the food-storage compartment into and out of thehydrator receptacle and a lowering of the humidity in the receptacle, so that vegetables and the like stored. in the hydrator receptacleare'dried out. Very slight circulation of such air is, however, desirable to prevent putrefaction and exchange of foododors within the receptacle when vegetables are stored therein.

It is, therefore, an object of my invention to provide a hydrator construction of the suspended type wherein th hydrator receptacle slides easily and wherein the cover seals the hydrator receptacle su-fiiciently to permit very little or no ventilation when the receptacle is in the closed position. v a

It is another. object. of my invention to pro vide a hydrator assembly of the suspended type wherein a high humidity is maintained. 7

These and other objects are effected by my invention as will. be apparent from thefollowing description and claims taken in accordance with the accompanying drawingsuforming a part of this application, in which:

Fig. 1 is a front view ofa refrigerator cabinet and hydrator assembly, illustrating my invention;

11-11 of Fig. 3; I

Fig. 3 is a partial sectional view taken on line IIL-III of Fig. 2; and

Figs. ,4 and 5 are details of the slide rails and pan member. v g

Referring specifically -'to the drawings for a detailed description of the invention, numeral II designates a refrigerator cabinet having an outer shell I2 and an innershell I3 defining a foodstorage compartment I4 provided with an access opening I5 and a door I6 for closing the access opening I5. Heat insulation I1 is provided be tween the shells I3 and I4 and an evaporator or cooling element I8 is disposed in the food-storage compartment for cooling and effecting a circulation of the air therein.

A hydrator assembly, indicated at I9. is preferably disposed'in the bottom of the food-storage compartment I4. A pan member is spaced from the wall of the food-storage compartment I4 at 2I, 22, and 23, to provide circulation of refrigeratedair around all sides of the receptaclefso that the interior is maintained at a low temperature by conduction of heat through the walls of the assembly to said circulatingair. A cover 24, preferably formed of plate glass, is spaced from the back of the food compartment I4 and from the door [6 and provides a closure for the pan member 20. The pan member 2;: and cover 24 form a closed container, commonly known as a hydrator, which is suitable for storing fresh vegetables and the lik out of contact with the dry air of the food-storage comtial quantities of air betweenthe flange 25 and the cover is prevented. The rails 25 are each provided with a lower flang 21 which slidably supports the pan member 20.

In accordance with myinvention. the upper flange 26 is substantially horizontal and the lower flang 2'! is inclined at an angle to the horizon Fig. 2 is a partial. side elevation taken on line/ tal, approaching th upper flange 26 adjacent the rear of the food-storage compartment 14, as best shown in Figs. 2 and 4. A flange: 23 is provided on each side of the pan member 20 to slide on the lower flanges 2'! of rails 25. flanges. 28 on the pan member are provided with humps or protuberances 29 adjacent the front thereof. When the pan member 20 is in its closed position beneath the cover 24, the rear of the pan is substantially closed by the cover because it is lifted by the inclined flanges 2'! on the rails 25, and the front of, the pan is substantially closed by the cover 24 because the front is lifted by the coaction of the protubcrances 29 with the The lower flanges 21 of the rails 25. Very little air circulation between the food-storage compartment l4 and the interior of the pan is, there fore, permitted. However, the pan member slides easily on the rails in spite of warpage of the flanges 28 on the pan member 20, because as soon as the pan member is pulled forward, the protuberances disengage the rails 25 and the clearance between the rear of the flanges 28 on the pan member and the upper flanges 2B of rails 25 progressively increases.

From the foregoing, it will be apparent that I have provided a suspended hydrator of improved design which is easily slidable to opened and closed positions, but which is sealed as tightly as desired when in the closed position. If it is desired to use the hydrator for other purposes than storing vegetables, for example, for storing bread, the clearances when the receptacle is closed may be reduced so that substantially no air from the food-storage compartment l4 enters the interior of the pan member 20.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
