Description

Variable Cool Air Supply Structure

The present invention relates to a variable cold air discharging structure, and more particularly, to a variable cold air discharging structure in which cold air discharge ports are opened and closed according to opening and closing of a door to discharge cold air from the cold air discharge ports or block discharge of cold air.

As illustrated in FIG. 1, a typical home refrigerator will be described as an example. The freezer compartment 20 and the refrigerating compartment 10 are provided inside the refrigerator body 1.

The freezing compartment 20 and the refrigerating compartment 10 are selectively opened and closed by a freezing compartment door 20 and a refrigerating compartment door 21 which are rotatably installed forward and backward on one side of the main body 1.

The cold air discharge unit 30 is provided at the rear of the freezing chamber 20. The evaporator 31 and the blowing fan 32 are installed in the cold air discharge unit 30.

The evaporator 31 generates cold air through heat exchange with a refrigerant flowing therein, and the blower fan 32 supplies the cold air to the freezing chamber 20 and the refrigerating chamber 10.

Meanwhile, a fan cover duct 33 is provided at the front of the cold air discharge part 30, that is, at the rear end of the freezing chamber 20.

However, the conventional refrigerator as described above has a problem in that cold air is provided only at the rear side so that freezing or cooling of the storage is delayed and the loss of cold air is large due to a temperature difference with the outside when the door is opened.

That is, when cold air is provided only at the rear side of the refrigerator, and the number of stored items is blocked, the freezing and cooling of stored items located at the front side are not properly performed.

The present invention has been made to solve the above problems is an object of the present invention has a side discharge hole to provide cold air from the side of the refrigerator, the side discharge hole is configured to open and close in conjunction with the opening and closing of the door. It is to provide a variable cold air discharge structure to prevent the loss of cold air.

In order to achieve the above object, the variable cold air discharging structure of the present invention includes a main body in which storage is stored, a cold air discharging part installed at an inner rear side of the main body to supply cold air into the main body, and connected to one side of the cold air discharging part. Cold air duct formed in the inner side, Side discharge hole formed in the cold air duct, characterized in that it comprises a switch for opening and closing the side discharge hole in accordance with the opening and closing of the door.

In addition, one side of the switch is connected to the outside of the cold air duct contact plate is formed to face, characterized in that the elastic member having an elasticity is inserted between the contact plate and the outside of the cold air duct.

In addition, the switch is characterized in that the through-hole having a size corresponding to the side discharge hole is formed in a position corresponding to the side discharge hole when the door is closed.

By installing a variable cooling air discharge structure having such a configuration, when the side discharge hole is opened and closed according to the opening and closing of the door, when the door of the freezing compartment is closed, the cooling air is supplied to the freezing compartment through the side to increase the cooling rate of the stored matter. It is easy to cool the storage, and when the door of the freezing compartment is opened, the cold air provided from the side is blocked to prevent the loss of cold air.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 to 4. Here, the same reference numerals are used for the same components as the prior art, and detailed description thereof will be omitted.

In the embodiment of the present invention, a freezer of a refrigerator is described as an example for convenience of description, where the refrigerator has the same configuration as a conventional refrigerator. That is, the refrigerating chamber 10 and the freezing chamber 20 are rotatably coupled to one side or both sides of the main body 1 and the main body 1 in which a storage space in which left and right or up and down sides are formed is rotatably coupled with the refrigerating chamber 10. It consists of the doors 11 and 21 which open and close the freezer compartment 20, respectively.

Here, the freezer compartment 20 is provided with a cold air discharge unit 30 for providing cold air into the freezer compartment 20 on the rear side of the freezer compartment 20, that is, the front face when the door 21 is opened.

As shown in FIG. 2, the cold air discharge unit 30 provides cold air to the inside of the freezing chamber 20 through the blower fan 32, and a plurality of discharges toward the wall surface of the outside of the freezing chamber 20. A fan cover duct 33 having holes formed in various directions is installed to provide cold air in various directions.

In addition, a cold air duct 22 is formed at one side of the cold air discharge part 30 to the side to provide cold air from the side of the freezer compartment 20 to the inside of the freezer compartment 20, and the cold air duct 22 is cold air. Side discharge holes 23 are formed to provide cool air from the duct 22 into the freezing chamber 20.

The side discharge hole 23 is provided at a side surface on which the door 21 is opened as the door 21 is opened and closed, and a cold air duct 22 is provided inside the side discharge hole 23, that is, the cold air duct 22. A switch 24 is installed to move along and open and close the side discharge hole.

At this time, the switch 24 is formed in a plate-like through-hole 25 corresponding to the side discharge hole 23, wherein the through-hole 25 coincides with the discharge hole 23 when the door is closed It is formed to.

In addition, one end of the switch 24 has a connecting shaft 26 protruding through one end of the cold air duct 22. In addition, a plate-shaped contact plate 27 is formed at the end of the connecting shaft 26 to be in contact with the door 21 from the outside of the cold air duct 22. In addition, an elastic member 28 is inserted between the outer surface of the cold air duct 22 and the contact plate 27, that is, the connecting shaft 26.

The operation of the variable cold air discharge structure according to the present invention configured as described above is as follows.

As shown in FIGS. 4A and 4B, when the door 21 is closed, the contact plate 27 is pushed by the door 21 so that the switch 24 is pushed toward the rear of the freezer compartment 20 as a whole and the side discharge is performed. The through-hole 25 of the hole 23 and the actuator 24 is coincident with the elastic member 28 is in a contracted state.

Accordingly, when the door 21 of the freezing chamber 20 is closed, the cold air moved from the cold air discharge unit 30 through the cold air duct 22 is supplied to the freezing chamber 20 through the side discharge hole 23.

On the other hand, when the door 21 is opened, the contact plate 27 is cold air duct 22 as the elastic member 28 compressed by the contact plate 27 in close contact with the door 21 returns to its original state. Move in the direction away from the end of the) and accordingly the switch 24 is moved so that the side discharge hole 23 and the through hole 25 is shifted to block the side discharge hole (23).

Accordingly, the cold air provided from the side surface is blocked while the door 21 of the freezer compartment 20 is opened.
