Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship merely to facilitate description of the invention and to simplify the description, and are not intended to indicate or imply that the referenced components or elements must be in a particular orientation, constructed and operative in a particular orientation, and are not to be construed as limiting the invention.
Example 1
Referring to fig. 1-3, the present invention is directed to a problem of reliability of return air of an air-cooled refrigerator in which an evaporator is horizontally disposed at the top of a compartment in the prior art by providing a return air structure in a receiving groove of a mask.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a cooling chamber air return structure which comprises a cover 2 and a top cover 11, wherein the top of an inner container 1 protrudes outwards, a containing groove 12 is formed in the upper surface of the cover 2, and a cooling chamber is formed between the containing groove 12 and the top cover 11; a first guide plate 21 and a second guide plate 22 are arranged in the containing groove 12 at the front end of the mask 2; the first guide plate 21 and the second guide plate 22 are both obliquely arranged, a gap between the first guide plate 21 and the second guide plate 22 is arranged to form a drainage port 221, an included angle is formed between the first guide plate 21 and the second guide plate 22, and the size of the included angle is between 25 degrees and 55 degrees; the gap between the first baffle 21 and the top cover 11 forms a first air return opening 121, and the second baffle 22 is provided with a plurality of second air return openings 222.
Further, an evaporator 5, a heater 4 and a water pan 3 are arranged in the accommodating groove 12; the evaporator 5 is in a flat cubic shape and is transversely arranged in the containing groove 12; one end of the heater 4 extends to the water outlet 221, and one end of the water receiving tray 3 extends to the inner surface of the first flow guide plate 21.
Example 2
Referring to fig. 1, a refrigerator includes a cooling compartment return air structure as above; the refrigerator comprises a refrigerator body, wherein an inner container 1 is arranged in the refrigerator body, and a cooling chamber and at least one storage space adjacently arranged below the cooling chamber are arranged in the inner container 1; a fan is also mounted at the rear end of the mask 2.
The first air return opening is not shielded by the second guide plate, and the air return opening cannot be seen from the front side of the refrigerator in a concealed design mode of the air return opening. When the door body of the refrigerator is not tightly sealed, hot air outside the refrigerator can be sucked into the cooling chamber, firstly, the hot air passes through the first air return opening 121, because the first air return opening 121 has no shielding structure, frost is not generated, and when the hot air passes through the second air return opening 222, the frost is generated on the surface of the second guide plate 22 and freezes because of the blocking of the second guide plate 22; when the evaporator of the refrigerator is stopped to defrost, the heater 4 works to melt the frost on the surface of the second flow guiding plate 22, because the second flow guiding plate is disposed in the mask accommodating groove 223, the defrosting water will flow into the water receiving tray 3 along the inner surface of the first flow guiding plate 21 through the water outlet 221, and then is discharged out of the refrigerator.
