DEFROSI WATER DRAIN MEANS Filed Aug. 4, 1966 INVENTOR. ROBERT L. McALusTER HlS ATTORNEY United States Patent 3,334,494 DEFROST WATER DRAIN MEANS Robert L. McAllister, Louisville, Ky., assignor to General Electric Company, a corporation of New York Filed Aug. 4, 1966, Ser. No. 570,335 3 Claims. (Cl. 62287) The present invention relates to a household refrigerator and is more particularly concerned with a refrigerator including improved means for disposing of condensate formed during defrosting of the evaporator or cooling unit component of the refrigerator.
Refrigeration including automatically defrosting evaporators require some means for collecting the the defrost water flowing from the evaporator during the defrost operation and for disposing of this water outside the cabinet.
A general object of the present invention is to provide a new and improved condensate disposal means for directing the flow of condensate from a fixed condensate collecting pan onto a Vertical liner wall of the refrigerator.
Further objects and advantages of the invention will become apparent as the following description proceeds and the features of novelty which characterize the invention will be pointed out with particularity in the claims annexed to and forming part of this specification.
In accordance with the illustrated embodiment of the present invention, there is provided a combination refrigerator comprising a one-piece liner having walls including vertical, rear and side walls defining a storage volume having an access opening at the front thereof. The rear wall has a vertical groove therein forming part of the condensate disposal means. A horizontal partition divides the interior of the storage volume into an upper freezer compartment and a lower fresh food compartment and contains an evaporator for cooling the air in both of the compartments. The partition also includes a pan-shaped condensate collecting member composed of sheet material and including a bottom wall and an upwardly extending rear flange adjacent the liner rear wall. The bottom wall of this member also forms the top wall of the fresh food compartment and includes a rearwardly sloping channel for collecting condensate from the evaporator. This channel terminates at its lower end adjacent the vertical groove in the linear rear wall. For the purpose of draining the condensate from the pan-shaped member, the flange of the pan-shaped member has an opening therein opposite and spaced from the vertical groove and this opening includes a horizontal bottom edge portion. A one-piece trough for bridging the space between the opening and the vertical groove is composed of a flexible material and includes a tapered rearwardly sloping bottom wall having a wide end for engaging the bottom surface of the channel and a narrow end extending into the vertical groove. A pair of arms extending upwardly from the tapered bottom wall and terminating in hook-shaped ends which are adapted to latch onto the bottom edge of the openings to provide means for supporting the trough in operative position. These arms are of the length effective to flex the trough and thereby wedge the trough between the pan-shaped member and the liner rear wall.
For a better understanding of the invention reference may be made to the accompanying drawings in which:
FIGURE 1 is a front view of a portion of the twotemperature refrigerator embodying the present invent1on;
FIGURE 2 is a vertical sectional view taken generally along line 2-2 of FIGURE 1; and
FIGURE 3 is a detailed view of a portion of the structure of FIGURE 2.
With reference to the drawing, there is illustrated one embodiment of the present invention in the form of a refrigerator comprising insulated walls including a onepiece liner 1 defining the total storage volume within the refrigerator and a horizontal partition generally indicated by the reference numeral 2 dividing this storage compartment into an upper freezer compartment 3 and a lower fresh food compartment 4. The access openings above and below the partition are respectively closed by a freezer compartment door 5 and a fresh food compartment door 6.
A single evaporator or cooling unit 7 for refrigerating both of the compartments is contained within the partition 2 and this evaporator forms part of a refrigeration system (not shown), most of the compartments of which are positioned in the lower portion of the cabinet.
The partition 2 comprises a lower member 10 of sheet material such as enameled sheet steel, including vertically extending flanges comprising a rear flange 12 by means of which the member 10 is rigidly secured to the rear wall 14 and to the opposed side walls 15 of the liner 1. The member 10 is substantially coextensive with the interior of the liner 1 and forms the top wall of the fresh food compartment 4. A body 16 of rigid foamed plastic insulating material such as a rigid polystyrene or polyurethane foam, is supported on the lower member 10 and is substantially coextensive with the cross section of the liner so as to thermally separate and insulate the two compartments. The body 16 is formed to define a major portion of a chamber for housing the evaporator 7, this chamber being covered or closed by a removable foamed plastic cover 17 which forms the top of the chamber. An upper member 18 of sheet material such as enameled sheet steel is removably positioned over the cover 17 and forms the bottom wall of the freezer compartment 3.
For the purpose of maintaining the two compartments 3 and 4 at desired operating temperatures, air is circulated from the two compartments into cooling relationship with the evaporator 7 and the cooled or refrigerated air returned to the two compartments by a fan 19. More specifically, air from the freezer compartment 3 is drawn into cooling relationship with the evaporator 7 through a louvered passage 20 in the forward end of the partition 2 and refrigerated air is discharged from the fan back into the freezer compartment through an airsupply passage 21. Air from the fresh food compartment 4 is drawn into heat exchange relationship with the evaporator 7 through a passage 22 and the cooled or refrigerated air is returned to the fresh food compartment through a passage 23 and a distribution mean-s 24.
For the purpose of periodically removing the frost which has collected on the evaporator 7, the cooling operation of the refrigerator is stopped and the evaporator 1 is warmed to defrosting temperature by energization of an electric heater 25 extending the length of the evaporator and positioned to Warm all areas of the evaporator and adjacent surfaces. The condensate or defrost water flowing from the evaporator collects on a metal plate 26 positioned below the evaporator and flows through an opening 27 in this plate and a cooperating opening 28 in the insulating body 16 into a channel 29 provided in the member 10. This channel 29 slopes rearwardly towards the rear wall 14 of the liner and terminates adjacent the rear flange 12 in a sump 30 defined in part by a sloping portion of the bottom of the member 10 and a. sloping portion of the flange bottom of the flange 12. An opening 31 in the flange 12 having, as is shown more clearly in FIG- URE 3 of the drawing, a horizontal bottom edge 32 provides means for discharging the frost water from the member 10.
By this arrangement the member in addition to forming the top wall of the fresh food compartment 4 also functions as a condensate collecting pan.
In order to convey the defrost water out of the cabinet, means are provided for directing the water flowing through the opening 31 onto the lower wall 14 of the liner. This water after flowing onto the bottom of the liner is disposed through a suitable drain opening into the machine compartment in accordance with the usual household refrigerator practices.
In accordance with the present invention, improved means are provided for assuring the proper flow of the condensate or defrost water onto the lower wall 14 of the liner and downwardly along the rear wall of the liner. To this end rear wall 15 is provided with a vertical groove 33 opposite to and adjacent the opening 31. For the purpose of bridging the space between the portions of the flange 12 adjacent the opening 31 and the groove 33, there is provided a one-piece trough 36 composed of flexible material (polyethylene) and shown in greater detail in FIGURE 3 of the drawing. More specifically, this trough 36 has a generally tapered bottom wall 37 having a narrower end 38 adapted to extend into the groove 33 and a wider end 39 adapted to engage the bottom surface of the channel 29 or more specifically the sump end thereof. Defrost water flowing onto the trough 36 through the opening 31 is channeled towards the tapered end 38 by means of the side walls 41) provided on the trough.
For supporting the trough 36 in operative position relative to the opening 31 and the channel 33 or more specifically in a sloping position bridging the space between these two components, the trough 36 is provided with a pair of spaced arms 41 extending upwardly from the top surface of the bottom wall 37 and terminating as shown in FIGURE 2 in hook-shaped end portions adapted to latch over the bottom edge 32 of the opening 31 and anchor the trough in the desired position. These arms 41 and associated latching or hook means facilitate the proper positioning of the trough. More specifically, the arms are of the length such as to require a flexing of the bottom wall of the trough as it is placed into position in order to obtain a latching of the arms onto the lower edge 32 of the opening 31. As a result, the trough is securely wedged between the adjacent surfaces of the panshaped member and the liner rear wall or more specifically the channel 33.
By this construction, the trough may be easily installed or removed without special tools or without the removal of any other parts of the cabinet. Furthermore this design permits the use of a relatively wide range of tolerances between the position of the member 10 and the rear wall 14 of the liner.
While there has been shown and described a specific embodiment of the present invention it will be understood that it is not limited thereto and it is intended by the appended claims to cover all such modifications as fall within the true spirit and scope of the invention.
