6 Claims. (Cl. 62-116) cabinet.

Another object of this invention is to provide improved means for sealing the aforesaid freezing compartment.

More specifically it is an object to provide an improved refrigerator cabinet providing a cooling compartment and to dispose a refrigerating element within the said cooling compartment, said refrigerating element being arranged to provide a freezing compartment for housing at least, one ice-making container in intimate thermal contact with said refrigerating element, and to provide for closing" said freezing compartment,

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred .form of the present invention is clearly shown.

In the drawing:

Fig. 1 is a front view in elevation of a refrigerator cabinet embodying features of this invention;

Fig. 2 is a view in cross-section of a portion of the refrigerator shown in Fig. 1 looking in the direction of the arrows 22 of Fig. 1;

Fig. 3 is a view in cross-section taken in the direction of arrows 3-3 of Fig. 1; and

Fig. 4 is an enlarged view of a sealing gasket forming a part of the present invention.

Referring to the drawing, the numeral 20 designates a refrigerator cabinet provided with a cooling compartment 21, and includes a. compartment 22 for enclosing a refrigerant circulating element for circulating refrigerant through a refrigerating element or evaporator designated 25. Any suitable refrigerant circulating element may be used for supplying refrigerant to the refrigerating element25, preferably, a refrigerating element of the compression type, for instance a refrigerating element similar to the type disclosed in the patent to H. B. Hull, No. 1,648,178, issued November 8, 1927.

The cabinet 20 includes walls 30 having an inner lining 31, and insulation 32 disposed between lining 31 and an outer covering 33. The cabinet 20 also includes an opening 35 closed by a door 36, which door closes the cooling compartment 21.

Referring more in detail to the drawing, the O refrigerating element 25 may be suspended within the cooling compartment 21 in any suitable manner, preferably, by the means 40. The refrigerating element includes a header 42 having a plurality of ducts or loops 43 and 44 arranged in staggered relation, and a valve plate 46. Any suitable valve mechanism may be employed for controlling the evaporator, preferably the usual float valve mechanism. The valve plate 46 includes a connection 48 for a suction pipe 49 and a connection 50 for a refrigerant pipe 52, which pipes may extend through an opening 54, of the cabinet 20, and lead to the refrigerant circulating element.

The refrigerating element 25 may be provided with means for forming a freezing compartment 61 having an open front 62. The means 60 includes a sleeve 65 which may be closed on the one end 66 thereof by any suitable means, and may include insulating means 70 secured to, and extending around, the open front 62 thereof, preferably, by rivets 71. The insulating means 70 may be of any suitable insulating material, preferably, rubber having a soft yielding portion 70a and a hardened portion 7017, the purpose of said insulating means being described hereinafter. The means 60 is arranged for housing a plurality of ice-making containers or trays and is provided with shelves 81 for supporting same. The sleeve 65 may be secured to the inner branches or loops 44 in any suitable manner, preferably, by solder. Thus the freezing compartment will be in thermal contact with the inner branches or loops 44 of the refrigerating element 25, while the outer branches or loops 43 may be employed for cooling the compartment 21 and for pre-cooling the air contacting with the means 60 forming the freezing compartment 61.

In order to provide means for effectually sealing the freezing compartment, the insulating means 70 has been provided. Thus the refrigerating element 25 is so positioned within the cabinet that the door 36 which closes the opening 35 of the cooling compartment 21 is employed for closing and sealing the open front 62 of the freezing compartment 61. Thus, the door 36 will engage the insulating means 70, which extends around the open end of the freezing compartment, to seal said freezing compartment in the manner shown in Figs. 2 and 3 in the drawing. Thus the soft portion 70a of the insulating means l yi Slightly to form a positive seal around the open end of the freezing compartment.

In order to improve the appearance of the interior of the cabinet 20, a baffle plate 90 has been provided. The baffle 90 may be secured to the sleeve by bolts 91, and may be used for hiding the loops 43 and 44, and the evaporator 42 from view from the front of the cabinet when the door 36 is open.- For the purpose of clear illustration, the bafile 90 is not shown in Fig. 1.

From the foregoing description it will be noted that there is provided an evaporator provided with means for forming a freezing, compartment adapted to house a plurality of ice trays, which freezing compartment is effectually sealed to prevent the circulation of air in said compartment to thus prevent the collection of moisture therein which would cause the trays to freeze tightly in place. It will also be noted that said freezing compartment is disposed in a cooling compartment in such a mamier so as to be sealed by the same door which closes the cooling compartment of said cabinet. Also that insulating means is provided for effectually sealing said freezing compartment. Thus the freezing compartment will be effectually sealed.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

1. In combination, a refrigerator cabinet forming a cooling compartment, a refrigerating element suspended in and exposed to the air within said cooling compartment, said refrigerating element-forming a freezing compartment having an open front, the front edges of said freezing compartment being relatively narrow, a gasket seal, extending around said open front of said freezing compartment, means for attaching said gasket seal to the front edges of said freezing compartment, said gasket seal having a groove therein fitting over the front edges of said freezing compartment, and a; door for closing said compartment and cooperating with said gasket seal for sealing said freezing compartment.

2. In combination, a refrigerator cabinet forming a cooling compartment, a refrigerating ele- 'ment disposed in and exposed to the air within said cooling compartment, said refrigerating element forming a freezing compartment having an open front, a gasket extending around the open front of said refrigerating element and being provided with means for receiving and concealing the edge of said refrigerating element adjacent said open front thereof, means engaging said gasket and said refrigerating element for securing the gasket in position, and a door for closing said cooling compartment and cooperating with said gasket for sealing said freezing compartment.
