Description
- The present invention relates to a refrigerator.
- In case of high ambient temperature and humidity, condensation may occur in some areas of a refrigerator. A known solution is to raise the temperature of these areas by using a heat source. For example, in a typical solution, an electrical heating component is disposed in areas where condensation occurs easily or a thermal tube in a refrigeration cycle of a refrigerator is arranged in these areas. In addition, Chinese Utility Model
CN202582004U discloses that a thermal guiding piece is used as a thermal bridge to connect a high-temperature area and a low-temperature area, thereby lowering the possibility that condensation occurs in the low-temperature area. DocumentsJP2013083364 WO2011036872 andDE102010028525 disclose refrigerators with similar structure of theirs drawers and their air circulation arrangements. - An object of the present invention is to provide a refrigerator which is advantageous for preventing dew.
- The present invention is disclosed in the independent claim 1. Further embodiments are disclosed in the dependent claims.
- We discover that when a refrigerator has a forced air cyclic system, if cold air that flows out of an evaporator compartment flows through areas where dew occurs easily, dew occurs more easily in these areas. Therefore, according to the present invention, cold air flowing towards a door is blocked to change a flow direction of the cold air, temperature difference between inside and outside of a corresponding side portion (for example, an upper side portion or left and right side portions) of a door which portion is adjacent to the cold air flow path and may have dew problems, may be decreased. This is advantageous for preventing temperature of the side portion (for example, an outer surface thereof) of the door being decreased to an extent that condensation occurs easily, and this can be achieved without increasing energy consumption of the refrigerator.
- According to the present invention, the refrigerator has a drawer located inside the storage compartment, and the cold air flow path is located between the wall and drawer.
- According to the present invention, the wall is a top wall of the storage compartment. This, in one aspect, is good for the reason that the cold air, which is flowed out of the cold air flow path disposed along the top wall, flows downwards to make the temperature inside the storage compartment more balanced, and in another aspect, it is advantageous for reducing possibility that dew occurs on the top portion of the door.
- By reducing cold air that passes between the drawer and the top wall to flow to the door or adjacent area of the door the door, it may be avoided that the temperature of the door, especially the top portion of the door that is close to the top wall of the storage compartment in a longitudinal direction, decreases to such an extent that condensation may occur easily or a high output heat source has to be used to increase the temperature thereon resulting in loss of more energy.
- In an embodiment, the cold air blocking portion may be close to a front wall of the drawer, which not only improves efficiency of preventing cold air from flowing through the gap by the cold air blocking portion, but also further helps to reduce impacts on an air circulation system of the refrigerator by the cold air blocking portion.
- In an embodiment, the cold air blocking portion may be located behind the front wall, so as to avoid clear exposure of the cold air blocking portion to the user and also avoid interference between the front wall of the drawer and the cold air blocking portion when the drawer is pulled. In addition, a gap required between the door and the drawer of the refrigerator in a front-rear direction is also not necessarily affected, that is, it is expectable not to change the structures of the door and drawer of the refrigerator to adapt to the cold air blocking portion.
- In an embodiment, the cold air blocking portion may extend in a horizontal direction along an upper end of the front wall of the drawer. For example, the cold air blocking portion extends horizontally along most of the width of the front wall of the drawer, so as to enhance blocking efficiency of the cold air blocking portion.
- According to the present invention, the cold air blocking portion and the front wall of the drawer overlap in a front-rear direction. The lower end of the cold air blocking portion is lower than an upper end surface of the front wall of the drawer, which therefore further helps to block cold air from blowing from the upper end of the drawer to the door of the refrigerator.
- In an embodiment, two ends of the cold air blocking portion do not exceed a corresponding sidewall of the drawer in a horizontal direction. For example, the two ends of the cold air blocking portion may be close to an inside of the corresponding sidewall of the drawer or the cold air blocking portion and an inner surface of the sidewall of the drawer are flush. In such a manner, the height of the sidewall of the drawer may be not necessarily confined by the cold air blocking portion.
- In an embodiment, a plurality of through holes may be provided on the front wall and/or a bottom wall of the drawer, and cold air turns downwards from the cold air blocking portion into the drawer and flows out the drawer via the through holes.
- In an embodiment, the cold air blocking portion is formed by an elongate protrusion bar protruding from the top wall.
- According to the present invention, the cold air blocking portion also includes a part of an inner liner of the cabinet and is directly integrated on a wall of the cabinet.
- In an embodiment, the door may include a handle groove located on a side portion of the door, and the cold air blocking portion and the handle groove overlap in a front-rear direction, so as to lower the possibility of condensation on a side portion having the handle groove.
- The present invention will become more fully understood from the detailed description given herein below for illustration only, and thus is not limitative of the present invention.
- As a part of the specification and for use of further understanding of the present invention, the specific implementation manners of the present invention are illustrated with reference to the accompanying drawings in the following, which are used in combination with the specification to illustrate the principle of the present invention.

air blocking portion 8 that at least partially covers the gap G between the front portion of thesecond drawer 72 and theupper wall 24 in a front-rear direction (that is, in the depth direction of the storage compartment 20). The coldair blocking portion 8 located in front of the cold air flow path AP prevents at least a part of cold air from flowing through the gap G towards the door 3, thereby reducing temperature difference between inside and outside of the upper side portion of the door 3. - The cold
air blocking portion 8 and thehandle groove 31 overlap in a front-rear direction which may reduce cold air from flowing to a side portion, having thehandle groove 31, of the door 3, so as to lower the probability of condensation in thehandle groove 31. - The cold
