1 Claim.
This invention relates to refrigerating apparatus and more particularly to tanks for use in connection with such apparatus.
One of the objects of my invention is to provide a refrigerating tank of a simple and cheap construction together with a simple and cheap method of constructing the same.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the present invention is clearly shown.
In the drawings:
Fig. l is a top plan view of a refrigerating tank embodying features of my invention;
Fig. 2 is a side view of the tank shown in Figure 1 together with a diagrammatic illustration of a refrigerant condensing element;
Fig. 3 shows a portion of the tank before bends;
Fig. 4 is a side view of the tank portion shown in Figure 3;
Fig. 5 is an end view of the tank portions shown in Figures 3 and 4 after bending; and
Fig. 6 is an enlarged view of a corner of the tank shown in Figure 1.
Referring to the drawing the numeral 20 designates in general my improved tank. The tank supporting walls include a sheet steel member 22 which forms the outer side and bottom walls and two end sheet steel members 24 which forms the outer end walls. The tank also includes an inner liner of thin stainless steel preferably .010 or less in thickness. The inner liner consists of sheet member 26 which forms the liner for side and bottom walls and sheet members 28 which form the liners for end members 24.
A refrigerant expansion coil 40 is secured to the side and bottom walls of the tank. Preferably the coil 40 is arranged in serpentine fashion. Refrigerant is supplied to the coil 40 through a supply conduit 42 under the control of a restrictor 44. Evaporated refrigerant is withdrawn from coil 40 through conduit 46 by the action of a motor-compressor unit 48. The unit 48 compresses the evaporated refrigerant and delivers it to a condenser 50 wherein it is condensed and from which it is delivered to the supply conduit 42.
The coil 40 is welded to sheet member 22 by resistance welding while sheet 22 is in the flat as shown in Figure 3. The liner member 26 is then cemented by any suitable material to the opposite side of sheet 22 while sheets 22 and 24 are in the flat thus forming the flat structure shown in Figure 3. This fiat structure is then bent along lines 58 indicated in Figure 4 to form a structure in the general form of a U as shown in Figure 5.
The end members 24 and liners 28 are cemented together when in the and then bent to form the cup shape as shown in Figure 1. The end members 22 together with their liners are then placed in the position shown in the completed tank disclosed in Figure l. The ends of the metal forming members 22, 24, 26 and 28 are welded together by melt down welding around their peripheries as shown at 50 in the enlarged view in Figure 6.
From the foregoing it will be noted that I have provided an inexpensive refrigerant tank. It will also be noted that it is lined with stainless steel to be corrosion resisting and that the liner and refrigerant coil are united to the supporting walls of the'tank before the supporting walls are bent thus facilitating the welding and cementing operations and avoiding manufacturing inaccuracies in the assembly of the tank. Such tanks may be used in so called ice cream cabinets and the like.
Although only a preferred form of the invention has been illustrated, and that form described in detail, it will be apparent to those skilled in the art that various modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claim.
I claim:
Refrigerating apparatus comprising, a supporting wall structure of U-shaped cross section forming bottom and opposite sides of a tank, a sheet material liner fitting complementary to the inner surfaces of said wall structure and united thereto, a serpentine refrigerant coil extending along and united to the outer surfaces of said wall structure, separate and oppositely disposed end wall members united to the sides and bottom of said wall structure, and separate and oppositely disposed liner members respectively united to the inner surfaces of said end wall members and also united to said first sheet material liner.
