AN ICE MAKER OF BOTTOM FREEZER TYPE REFRIGERATOR

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an icemaker of a combi refrigerator, and more particularly, to an icemaker of a combi refrigerator that prevents outflow of cold air to prevent ice from melting.

The refrigerator is divided into Top Mount, Bottom Freezer, and Side by Side refrigerator depending on the location of the freezer and refrigerator.

The top-mounted refrigerator has a structure in which the freezer compartment is located above the refrigerator compartment, and the refrigerator compartment is slowly cooled by natural convection or forced convection to cool the refrigerator compartment.

Combi refrigerator is located in the upper part of the freezer compartment, so it is easy to use ergonomically. That is, most foods are stored in the refrigerator compartment rather than in the freezer compartment, which is convenient because the food stored in the refrigerator compartment can be taken out and brought in without bending the waist.

Yangmoon casement refrigerator is located in the side of the freezer and refrigerator room side by side, easy to open and close the door and easy to store food.

In recent years, the consumption of combi refrigerators with ergonomic characteristics has been gradually increasing as the number of one-person residential types such as one-room apartments is increasing.

If the dispenser is installed in the Combi refrigerator, its location must be in the refrigerating compartment. This is because the use of water or ice in the lower freezer is very inconvenient.

Accordingly, when the ice maker is installed, the position of the ice maker should naturally be located inside the refrigerator room maintaining the temperature of the image. The ice maker is connected to a lower freezing chamber having an evaporator by a separate duct to maintain the ice producing temperature.

Generally, the ice maker of the Combi refrigerator includes an ice producing box for storing and storing ice, and an ice conveying discharging unit for conveying the manufactured ice combined with the ice producing box.

In this case, the ice transfer unit needs to be detachably installed in the ice producing box for maintenance or a large amount of draw. However, if a separate sealing structure is not provided between the ice transfer outlet and the ice-producing box, there is a problem that the cold air easily flows out into the refrigerating chamber and the ice melts.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an ice maker for a combi fridge that can prevent cool air from flowing out of the ice maker box into the refrigerator compartment and can be conveniently assembled.

In order to achieve the above object, an icemaker of a combi refrigerator according to the present invention comprises:

An ice producing box communicating with the freezing chamber and having an opening formed at a front side thereof and a catching groove formed at both sides of the front side thereof, a ice conveying discharging portion provided at an opening of the ice producing box so as to be freely detachable, And a lock unit having a hook formed in the latching groove and a driving unit for operating the lock unit.

In this case, the ice-

An ice storage container, an ice transfer mechanism for transferring ice in the ice storage container, a sealing lid plate for closing the opening of the ice producing box, and an ice discharge portion provided in front of the sealing lid plate, Is installed on the front side of the vehicle.

Further, the lock portion is rotatably installed on the sealing lid plate, has a hook protruding backward, and is connected to the sealing lid plate by elastic restoring means.

The lock portion is disposed in the transverse direction with respect to the sealing lid plate, and at one end thereof, a driven portion having a surface inclined inwardly toward the lower side, and the driving portion is disposed to face the inclined surface of the driven portion .

Further, the sealing lid plate is characterized in that a stopper for restricting the rotation of the lock portion is formed.

The ice discharger may be provided with an ice crusher.

According to the present invention as described above, it is possible to reliably prevent the cool air from leaking from the ice-making box constituting the ice maker into the refrigerating compartment when the ice-maker is installed in the refrigerating compartment of the combi refrigerator, It is advantageous in that it is easy to perform maintenance and the operation of taking out a large amount of ice at one time can be conveniently performed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the forward direction indicates the portion where the refrigerator door is located, and the rearward direction indicates the opposite side.

As shown in the drawings, the present invention relates to an icemaker 200 applied to a combi fridge in which a freezing chamber 110 is located at a lower portion and a refrigerating chamber 120 is located at an upper portion.

More specifically, the ice maker 200 according to the present invention includes an ice producing box 210 having an opening 211 fixed to the inside of the refrigerating chamber 120, And an ice transfer unit 220 in which a detachable and detachable ice transfer unit 220 is installed.

The ice-making box 210 is in communication with the freezing chamber 110 by a separate duct (not shown), so that the ice-making temperature is always maintained. Inside the ice-producing box 210, there are provided an ice-producing unit and an ice-dropping unit such as a twister. The ice maker has a wide container shape and has a conventional structure in which a plurality of compartments are formed. The twister twists the ice maker in the longitudinal direction to separate ice.

On both sides of the front side of the ice-making box 210, a hooking groove 212 is formed so that a hook 231 of a lock portion 230, which will be described later, is hooked.

The ice transfer unit 220 includes an ice storage container 221, an ice transfer mechanism 222 for transferring ice in the ice storage container 221, a seal closing the opening 211 of the ice production box 210, A cover plate 223, and an ice discharge unit 224 provided in front of the sealing cover plate 223. [

As shown in the drawing, the ice transfer mechanism 222 is installed in the ice storage container 221 and may have the form of a coil. Of course, the ice transfer mechanism 222 may have other structures known outside the coil form.

A lock part 230 is provided in front of the ice transferring and discharging part 220 and formed with a hook 231 engaged with the latching groove 212 of the ice generating box 210. That is, two hooks 231 are formed on the lock part 230 so as to be engaged with the latching grooves 212 formed on both sides of the ice-making box 210.

In this case, the latching groove 212 has a clearance formed in the vertical direction so that the hook 231 can be moved up and down. That is, when the hook 231 moves to the entrance of the latching groove 212, the hook 231 can be pulled out as it is.

The lock portion 230 is rotatably mounted on the sealing lid plate 223 of the ice transfer unit 220. Specifically, the lock portion 230 is installed on the sealing lid plate 223 with the rotation shaft 234 interposed therebetween, and is formed to be long in the lateral direction.

The locking part 230 is connected to the sealing lid plate 223 by elastic restoring means 235 such as a spring so that the sealing lid plate 223 can elastically deform the opening 211 of the ice producing box 210 As shown in FIG. In the figure, elastic restoration means 235 is connected to the sealing lid plate 223 at one end about the rotation axis 234.

A gasket (not shown) may be provided around the sealing lid plate 223 to closely contact the opening 211 of the ice producing box 210.

On the other hand, the lock portion 230 is rotated by the driving portion 240. The driving unit 240 may be installed on a frame or a cover 290 extending the ice generating box 210.

At one end of the lock portion 230, a driven portion 236 having a surface tilted inward toward the bottom is formed. The driving unit 240 is arranged to face the inclined surface of the driven unit 236.

Accordingly, when the driving unit 240 is pressed against the driven unit 236, the driven unit 236 is pushed in an inclined state, so that the locking unit 230 can be rotated with respect to the rotating shaft 234.

In the drawing, the driving unit 240 is configured as a button, and the front side of the button protrudes in a curved shape. However, such a shape is not particularly limited, and it is sufficient that the driven portion 236 of the lock portion 230 can be operated upward by depressing the button.

Further, a stopper 237 for limiting the rotation of the lock portion 230 is additionally formed on the sealing lid plate 223 to prevent rotation at an excessive angle.

As shown in the figure, an ice crusher (not shown) having a known structure may be installed in the ice discharger 224.

Hereinafter, the function of the icemaker of the combi refrigerator according to the present invention will be described.

First, a button constituting the driving unit 240 is pressed in a state where the ice transfer unit 220 and the ice producing box 210 are assembled.

As the driving unit 240 advances, the locking unit 230 overcomes the elastic force of the elastic restoring unit 235 and rotates counterclockwise about the rotation axis 234 while pressing the driven unit 236.

At the same time, the engagement of the hook 231 of the lock portion 230 engaged with the engagement groove 212 is released.

When the sealing cover plate 223 is pulled in this state, the hook 231 of the lock portion 230 comes out of the catching groove 212 of the ice-making box 210, so that the ice- It can be completely separated from the box 210.

Conversely, when inserting the ice transfer unit 220 into the ice producing box 210, the hook 231 of the lock unit 230 may be pushed in as it is while confirming the position of the catching groove 212 with the naked eye. Since the hook 231 of the lock part 230 and the engagement groove 212 of the ice producing box 210 are firmly coupled by the elastic force of the elastic restoring unit 235, The sealing lid plate 223 is brought into close contact with the opening 211 of the ice producing box 210 so that the cool air does not flow out.
