Definitions

• the present invention relates to a refrigeration device that includes horizontal evaporators that are arranged in a freezer or a freezer compartment of the refrigeration device.
• These evaporators are installed on the side walls of the freezer compartment.
• the object of the present invention is to improve the current locking systems of the horizontal evaporators of the freezer of the refrigerator.
• the invention basically consists of some holding elements of the evaporators, which ensure their completely secure attachment and immobility.
• the horizontal evaporators are usually attached to the side walls of the freezer compartments of the refrigeration appliances using a large number of elements, which are extremely complex.
• the invention proposes a refrigeration device that includes a fastening system to secure horizontal evaporators that are located inside a freezer compartment or a freezer trough of the refrigeration device fasten.
• a fastening function For this purpose, the corresponding holding element is inserted into a side receptacle of the trough until a cutout of the element engages in an evaporator tube. As soon as this intervention has taken place, a lever function is exerted on the opposite side of the element until central pins or beads of the holding element engage below the wires of the corresponding evaporator.
• a management function for the compartments of the freezer If the holding elements are already attached to each of the ends, front left and right of the evaporator, it is sufficient to attach two further elements to the rear left and rear right, so that there are four support points for the compartment of the freezer. In this way, the compartment remains supported at four points, while at the same time the corresponding elements serve as guide elements during the pulling out and insertion of the compartments.
• a stop function for the compartments of the freezer is sufficient to fulfill the stop function for the compartments, with the necessary forms being implemented in the latter.
• the fastening of the evaporator is very stable due to the lever function of the holding elements, so that unwanted noises and vibrations that occur with other, conventional fastening systems are avoided. It is also important to emphasize that thanks to the new holding elements, the evaporators are particularly rigid and solid.
• thermoforming of the trough proves to be cleaner and easier.
• Figure 1 is a perspective view of a freezer compartment or freezer pan of a refrigerator which includes at least one horizontal evaporator inside which is secured to the side walls of the wall by means of a fastening system about which the object of the present invention revolves.
• FIG. 2 is a front view of the freezer, showing the holding elements that make up the fastening system. These holding elements serve to support and guide a conventional compartment which is arranged inside the trough.
• FIG. 3 is a longitudinal sectional view, essentially showing the snap-in of the evaporator in the bulges of the snap-in elements or holding elements. Furthermore, a compartment is shown with a lower projection, which serves as a stop during pulling out.
• Figure 4 is a perspective view of the holding member.
• the refrigeration device comprises a freezer trough 1, in the interior of which at least one horizontal evaporator 2 is arranged, which in principle rests on seats or support elements 3 which are firmly connected to the side walls 4 of the trough 1 of the cooling device.
• the evaporator 2 comprises a structure made up of tubes 5 and parallel wires or rods 6 connected to the tubes 5, so that the evaporator 2 rests on the seats 3 over a part of the tubes 5 which is connected to the edges of the tube 5 Evaporator 2 matches.
• the evaporator 2 is fastened with the aid of holding parts or holding elements 7 which are located above the evaporator 2 in accordance with some of the seats 3 of the side walls 4 of the trough 1.
• holding parts or holding elements 7 which are located above the evaporator 2 in accordance with some of the seats 3 of the side walls 4 of the trough 1.
• each holding element 7 acts as a lever, so that the element 7 forms a stop through one of its ends against a surface 9 of the respective recess 8 of the side wall 4 of the trough 1, while the holding element 7 simultaneously downwards against the tube 5 of the evaporator 2, which rests on the respective seats 3.
• the fastening position of the holding element 7 takes place with the aid of pins or lateral beads 10 which are arranged in a central zone of the holding element 7 and which engage in a pair of rods 6 adjacent to the evaporator 2.
• the holding element 7 includes lower cutouts 11 which coincide exactly with the pressure points of the holding element 7 against the part of the tube 5 of the evaporator 2, so that the tube 5 engages in these cutouts 11, as a result of which the evaporator 2 is secured more firmly and more securely ,
• the holding element 7 generally comprises a U-shaped section, the two side branches or side wings 12 of which are affected by the lower cutouts 11 and which at the same time also enclose the central engagement beads 10, so that the latter 10, even if they are normally on the outer surfaces the wing 12 are located, could also be located on the inner surfaces of the parallel wings 12.
• the holding element 7 essentially has a symmetrical structure with respect to the transverse plane, which extends through the beads 10, whereby two symmetrical arms are created, so that the lower cutouts 11 are arranged on both end sections of the parallel wings 12. In this way, the holding element 7 can be inserted into the receptacle 8 of the side walls 4 of the trough either through one or the other end.
• the arms of the holding element 7 could have an asymmetrical structure, that is to say that each arm could have a different length.
• end portions of the wings 12 are affected by inclined planes 13 which run upward from the lower cutouts 11 to the ends of the holding element 7.
• the holding elements 7 serve as a support and guide for conventional compartments 14 which are located in the freezer compartment 1, while at the same time they act as stop elements during the pulling out of the compartments 14 serve.
• the compartments include lower projections 15 in their base area.
