Abstract

A refrigerating chamber evaporator is assembled in the refrigerator in the non protruding exposure form; the back wall surface of an inner refrigerator is provided with an installing groove; then a cooling plate in the appropriate size is installed in the front of the evaporator. A refrigerating chamber evaporator assembly construction constructed in such a way can enlarge the effective inner volume of the refrigerating chamber and enhance the cooling efficiency.

Description

Refrigerating chamber evaporator assembly construction of direct cooling refrigerator

The utility model relates to when the effective internal volume of refrigerating chamber increases in the direct cooling refrigerator, makes the assembly structure of the direct cooling refrigerator refrigerator evaporator of cooling effectiveness raising.

The assembly structure of prior art as shown in Figure 3, there are some shortcomings like this: because the refrigerator evaporator (9) of general direct cooling refrigerator (3) is to take the state of protruding dew to install in refrigerating chamber (1) inside, so not only reduced effective internal volume of refrigerating chamber (1), and, make food be easy to freeze because cold air is directly passed to food.Simultaneously, be frozen in the frost on the above-mentioned evaporimeter (9) and when defrosting operation, the white water of formation is not wandered along the rear surface (6) of interior case, but directly drips from the below of evaporimeter (9) when removing.In order to receive these white water and, will to make the bead (4) of interior case rear surface (6) rhone high laterally prominent to water spilage tray (11) draining.For this reason, the rhone bead is in refrigerator manufacturing process, because the influence of evaporimeter (9) and rhone bead (4), the case rear surface carried out the foaming operation of heat-barrier material in frothing clamp can't keep under indeformable state, and the peripheral position of interior case rear surface evaporimeter (9) also is easy to generate distortion.

The purpose of this utility model is to be provided as the assembly structure of the direct cooling refrigerator refrigerator evaporator that solves above-mentioned shortcoming, when the assembling refrigerator evaporator, make evaporimeter not protruding dew in refrigerating chamber, so that make the corresponding increase of the effective internal volume of refrigerating chamber, simultaneously, cooling effectiveness also increased.

For achieving the above object, the suitable position of the utility model case rear surface in direct cooling refrigerator is provided with mounting groove, after in this mounting groove, assembling refrigerator evaporator, the coldplate that the lower end is reached the rhone lip portions is contained in the front of evaporimeter, thereby evaporimeter is not protruded in case and appears.

If according to the utility model, because refrigerator evaporator is inlaid in the suitable position of case rear surface in the direct cooling refrigerator, and load onto coldplate in its front, the institute so that evaporimeter no longer in case, expose, thereby increased effective internal volume of refrigerating chamber, cooling effectiveness is improved to greatest extent, simultaneously, also promoted the aesthetic property of indoor design.

With reference to accompanying drawing the utility model most preferred embodiment is given detailed explanation.

Fig. 1 is an oblique view of using refrigerator of the present utility model,

Fig. 2 is the lateral sectional view that has shown the utility model confined state,

Fig. 3 is the refrigerator oblique view of prior art.

Assembly structure of the present utility model is in the direct cooling refrigerator that refrigerating chamber (1) and refrigerating chamber (2) are set, the rhone edge is projected upwards, the suitable position of case rear surface (6) is provided with mounting groove (7) in the refrigerator that drainpipe (5) are housed, and assembling is connecting the refrigerator evaporator of Defrost heater, make it not be inlaid in the casing of refrigerating chamber (1) projectedly, then, the coldplate that the lower end is arrived rhone bead (4) position is contained in the front of above-mentioned evaporimeter, makes it and will not appear.

Shown in figure (2), because the refrigerator evaporator (9) that connects Defrost heater (8) is inlaid in the formed mounting groove of suitable position of the interior case rear surface of direct cooling refrigerator (3) (6), then, load onto the coldplate made from aluminium sheet (10) in its front, so, above-mentioned evaporimeter is neither protruded in case also no longer to be appeared, because, when using refrigerator, the cold air that produces from evaporimeter (9) is transmitted on the coldplate (10), and then be delivered to equably in the refrigerating chamber, increase heat transfer area, thereby can improve refrigeration efficient to greatest extent.In addition, behind long-term use refrigerator, on coldplate (10), tied under the white situation, during the desire defrosting, as long as make the Defrost heater action, heat is transmitted on the coldplate (10) through evaporimeter, just removed frost, at this moment, frost dissolves the water of formation owing to be subjected to the bottom to reach the guiding of the coldplate (10) of rhone flaunching part (4), the rear surface (6) of case in the refrigerating chamber and wandering in the rhone projecting edge, then, be transported in the water spilage tray (11) by the drainpipe (5) that is connected in the rhone flaunching part (4), after this, rely on the heat that produces from compressor reducer (12) and make it evaporation.

The utility model as above, refrigerator evaporator is contained in the interior formed mounting groove of case rear surface (6) (7), and at its front assembling coldplate (10), because the cause of this coldplate, formed evaporimeter and neither protruded also blind structure, thereby increased the dischargeable capacity of refrigerating chamber (1), simultaneously, cooling effectiveness also is to maximize, and has beautified the design of interior case rear surface.

Claims

1, the assembly structure that is used for the refrigerator evaporator of direct cooling refrigerator is characterised in that: the suitable position of case rear surface (6) forms mounting groove (7) in refrigerating chamber, the evaporimeter that is linking Defrost heater (8) (9) setting-in within it after, do not appear for above-mentioned evaporimeter is neither protruded in the refrigeration chamber yet, the coldplate (10) that the lower end reaches rhone bead (4) position is installed in its front.
