Be described in detail with reference to the attached drawings refrigerator below according to the embodiment of the invention.
Fig. 1 shows refrigerator according to an embodiment of the invention, and is as shown in Figure 1, comprises according to the refrigerator 10 of the embodiment of the invention: a casing 1 and a door body 2.
Be limited with refrigeration space 11 in the said casing 1; Evaporimeter 12 and fan assembly 13 are installed on the rear wall in the casing 1; Fan assembly 13 is installed on evaporimeter 12 tops; Be separated with assembling and locking evaporator cover plate 14 between between evaporimeter 12 and the refrigeration space 11, evaporimeter cover plate 14 tops are connected with between the diapire of air channel cover plate 15 and evaporimeter cover plate 14 bottoms and refrigeration space 11 and are limited with return air inlet 141, and return air inlet 141 is used to make the cold of refrigeration space 11 to flow back to evaporimeter 12 bottoms along return air inlet 141.
Thus, can increase the cold of refrigeration space 11 bottoms, dwindle the temperature difference of refrigeration space 11 bottoms and refrigeration space 11 other positions, make temperature more even, reduce energy consumption.
According to one embodiment of present invention, the top of air channel cover plate 15 is connected on the inner roof wall of casing 1 between the interior rear wall of casing 1 and air channel cover plate 15, to limit upper air duct 15.Thus, the cold that evaporimeter 12 produces can be under the effect of fan assembly 13, upwards flows along the upper air duct 151 that limits between the interior rear wall of casing 1 and the air channel cover plate 15.
According to one embodiment of present invention, as shown in Figure 2, air channel cover plate 15 is provided with the air inlet 1511 of a plurality of connection upper air ducts and refrigeration space.Thus, the cold of evaporimeter generation can flow into refrigeration spaces along air inlet 1511.
According to one embodiment of present invention, as shown in Figure 3, evaporimeter cover plate 14 comprises and evaporimeter 12 and fan assembly 13 corresponding straight plate parts 142 and the arc 143 that is connected straight plate part 142 lower ends.Thus, original air port, straight plate part 142 lower ends is blocked by arc 143, and cold can not directly flow back to evaporimeter 12 from straight plate part 142 lower ends, has increased the time of staying of cold air in refrigeration space 11, has strengthened refrigerating effect.
According to one embodiment of present invention, arc 143 has identical radian with casing 1 inwall bottom 111.Thus, arc 143 just can be suspended from casing 1 inwall bottom 111, and limits return air inlet 141 between arc 143 and the casing 1 inwall bottom 111.
According to one embodiment of present invention, the bottom of refrigeration space 11 is provided with down drawer 112, and return air inlet 141 is positioned at drawer 112 belows down.Thus, the cold air that from evaporimeter 12, flows out is under the effect of blower fan group 13; Get into refrigeration space 11 through upper air duct 151 and air inlet 1511; Cold in the refrigeration space 11 flows back to evaporimeter 12 from following drawer 112 belows again, accomplishes the circulation of cold air, and this circulating cold air mode has increased the cold that time drawer 112 can receive; Dwindled the temperature difference of other positions in time drawer 112 and the refrigeration space 11; Make refrigeration space 11 temperature more even, reduce energy consumption of refrigerator, make the more effect of environmental protection of refrigerator thereby reach.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means the concrete characteristic, structure, material or the characteristics that combine this embodiment or example to describe and is contained at least one embodiment of the present invention or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete characteristic, structure, material or the characteristics of description can combine with suitable manner in any one or more embodiment or example.
Although illustrated and described embodiments of the invention; Those having ordinary skill in the art will appreciate that: under the situation that does not break away from principle of the present invention and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited claim and equivalent thereof.
