Description

Refrigerator with air curtain generator

The present invention relates to a refrigerator having an air curtain generating device, and more particularly, to a refrigerator provided to supply cold air into a door pocket provided on an inner side of a door when the door is closed by using the air curtain producing device.

1 illustrates a conventional refrigerator, and illustrates a refrigerator having an air curtain generating device that generates an air curtain blocking an opening of a door according to opening of a door of a conventional refrigerator. As shown in FIG. 1, the refrigerator is provided in the cabinet 10 forming the freezer compartment 21 and the refrigerator compartment 22 partitioned by the partition 27, and the freezer compartment 21 and the refrigerator compartment 22, respectively. It has the freezing chamber door 24 and the refrigerating chamber door 25 which open and close the freezing chamber 21 and the refrigerating chamber 22.

A compressor 23 is provided at the lower rear of the cabinet 10, and an evaporator 29 is installed at the rear of the freezer compartment 21 to generate cold air by evaporating the refrigerant supplied from the compressor 23. In the upper part of the evaporator 29, a cooling fan 19 is provided which blows cold air generated by the evaporator 29 and supplies it to the freezing chamber 21 and the refrigerating chamber 22.

An air curtain generating device 20 is installed above the refrigerating chamber 22. The air curtain generating device 20 is composed of a cold air duct 13 installed in the upper portion of the refrigerating chamber 22 and a blowing fan 11 for blowing cold air generated in the evaporator 29 into the cold air duct 13. The cold air duct 13 is formed at its end with a cold air outlet 15 downwardly opened in a region adjacent to the opening of the refrigerating chamber 22. The cold air blown into the cold air duct 13 is discharged downward through the cold air discharge port 15, thereby creating an air curtain blocking the opening of the refrigerating chamber 22.

The refrigerating chamber 22 is provided with a door opening and closing detection sensor (not shown) for detecting the opening and closing state of the refrigerating chamber door 25, and the blower fan 11 is opened by the door opening and closing detection sensor. It is controlled to operate only when detected. Therefore, the air curtain is generated only when the refrigerating chamber door 25 is opened to block the leakage of cold air through the opening of the refrigerating chamber 22 in the open state of the refrigerating chamber door 25.

On the rear wall surfaces of the freezing chamber 21 and the freezing chamber 22, a plurality of cooling mechanisms 16 and 18 are formed. In the closed state of the refrigerating chamber door 25, the cold air generated in the evaporator 29 is blown by a cooling fan 19 installed above the evaporator 29, and the freezing chamber 21 and the refrigerating chamber are passed through the respective cooling mechanisms 16 and 18. (22) is supplied, thereby freezing and refrigerating the food contained in the freezer compartment 21 and the refrigerating compartment 22.

However, such a conventional refrigerator has a problem that cooling near the door is difficult to achieve efficiently. When the refrigerator door is opened or closed, a portion adjacent to the door is in direct contact with the outside air, thereby rising to the temperature of the outside air within a short time. However, in the conventional refrigerator as described above, the space adjacent to the door, in particular, the space inside the pocket provided on the inner side of the door is not directly cooled, making it difficult to achieve rapid uniform cooling.

Accordingly, an object of the present invention, in consideration of the above problems, by using the air curtain generating device to quickly cool the space adjacent to the door in the cooling chamber and the space inside the pocket installed in the door to uniform the cold air in the cooling chamber It is to provide a refrigerator that can achieve the distribution.

According to the present invention, there is provided a cabinet for forming a cooling chamber, a door provided in the cooling chamber to open and close an opening of the cooling chamber, and a food storage pocket on an inner side thereof, and an evaporator for generating cold air. A refrigerator, comprising: a cold air duct having cold air suction openings respectively opened in regions adjacent to the evaporator at both ends, and cold air discharge openings opening in regions adjacent to the opening of the cooling chamber; A blowing fan that blows in the cold air duct and discharges cold air from the evaporator through the cold air outlet; A steering plate disposed adjacent to the cold air discharge port and configured to control a direction of the cold air discharged through the cold air discharge port; Door opening and closing detecting means for detecting an open / closed state of the door; And controlling the steering plate according to a detection result of the door opening / closing detecting means, to generate an air curtain blocking the opening of the cabinet when the door is opened, and to supply cold air into the pocket when the door is closed. It is achieved by a refrigerator characterized in that it comprises a means.

The steering plate control means may include a push switch installed in the cabinet and pressed and released by the door in the open and closed states of the door to change respective positions of the steering plate; And a spring member elastically supporting the push switch.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
