Description

Door fastening device of refrigerator

The present invention relates to a door lock of the refrigerator, and more particularly to a door lock of the refrigerator to prevent the door from opening unnecessarily.

In general, the refrigerator includes an evaporator in a cooler chamber, which is a separate space provided at the rear side of the freezer compartment, and generates cold air in the evaporator according to the operation of the compressor installed in the machine room. It is a device that freezes and refrigerates the inside of each refrigerator according to a series of cold air flows back to keep food stored in the refrigerator for a long time.

The front of the freezer compartment and the refrigerating compartment of the refrigerator is provided with a door to seal or open the inside of the refrigerator, the door is opened by pulling the door handle provided in the door.

Hereinafter, a conventional SBS refrigerator will be described with reference to the drawings.

1 is a front view showing the appearance of the SBS refrigerator according to the prior art, as shown, both sides of the main body 10 is formed with a freezer compartment and a refrigerating compartment, respectively, the front side of the freezer compartment and the refrigerating compartment and the outside of the freezer compartment and The first door 20 and the second door 30 for preventing the flow into the refrigerating compartment and the cold air inside the freezer compartment and the refrigerating compartment to the outside are rotatably mounted using hinges, respectively. The door handles 40 are mounted on one side of the front part of the two doors 20 and 30, respectively.

In addition, a rubber gasket is attached to the inner edges of the first and second doors 20 and 30 to seal the freezing compartment and the refrigerating compartment, and the gasket is in close contact with the main body 10 using magnetic force. The connecting magnetic body is embedded so as to be closed, and generally has a predetermined closed space to absorb shock when the first and second doors 20 and 30 are closed.

However, in the SBS refrigerator according to the prior art, since the door handle 40 is protruded in front of the first and second doors 20 and 30, the doors are frequently opened and closed by the infants unnecessarily. As a result, the cool air inside the refrigerator is leaked and there is a problem in that power consumption increases in the process of regenerating the cold air to compensate for this.

In addition, since the conventional door is not provided with a separate locking means, there is a problem that the door is opened while carrying the refrigerator. Therefore, in the related art, in order to prevent the door from being opened before transporting the refrigerator, the main body and the door have to be pasted with an adhesive tape, or tied with a string.

In order to solve this problem, a key bundle may be installed on the door, such as a commercial refrigerator.

However, if a key bundle is installed in the door of the refrigerator, only the person who holds the key can open the door, so that inconvenience occurs when the refrigerator is frequently used.

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to prevent the opening of the door unnecessarily to prevent the leakage of cold air inside the refrigerator and lower the power consumption of the refrigerator door To provide a lock.

In addition, another object of the present invention is to provide a door locking device of the refrigerator configured to prevent the door from being opened while carrying the refrigerator.

In addition, another object of the present invention is to provide a door locking device of the refrigerator configured to lock both doors of the double-door refrigerator at the same time.

The door lock device of the refrigerator of the present invention for achieving the above object, in the refrigerator consisting of a main body in which the storage space is formed, the door opening and closing the front of the main body, the door handle is hinged to the door and And a support bracket coupled to the door handle, the link having a latch and a locking bracket formed to engage the latch.

Here, the door handle is preferably composed of upper and lower fixed handles fixed to the door, and a rotary handle provided between the upper and lower fixed handles.

In addition, it is preferable that one side of the link is further provided with a stopper for limiting the rotation.

The door is divided into a first door and a second door, and the door handle and the link are installed in the first door, and the support bracket is installed in the second door.

On the other hand, the support bracket is preferably installed in the body.

According to the door lock device of the refrigerator according to the present invention, the latch is inserted into the support bracket by the rotation of the door handle to prevent the door from being opened unnecessarily, preventing cold air from leaking inside the refrigerator and lowering the power consumption of the refrigerator. Provide effect.

In addition, since the door is not opened during the transportation of the refrigerator, there is an advantage in that the transportation of the refrigerator is easy.

In addition, the latch is installed on the first door and the support bracket is installed on the second door to provide an effect that can simultaneously lock both doors of the double-door refrigerator.

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

Here, Figure 2 is a front view showing a refrigerator according to the present invention, Figure 3 is a front sectional view showing a refrigerator according to the present invention, Figure 4 is an enlarged perspective view showing a door locking device of the refrigerator according to the present invention, 5 is a perspective view showing the operating state of FIG.

First, referring to the internal structure of the refrigerator with reference to FIGS. 2 to 3, the refrigerator (A) of the present invention is divided into a left and right or up and down inside the refrigerator compartment 110 and the freezer compartment 120 is divided into a storage space. The main body 100 is formed, and the first and second doors 210 and 220 are mounted on one side or both sides of the main body 100 to open and close the refrigerating chamber 110 and the freezing chamber 120. The apparatus is provided with a mechanism (not shown) for forming a cooling cycle consisting of a compressor, a condenser, an evaporator, and the like.

In addition, door handles 310 and 221 are mounted on one side of the front portion of the first and second doors 210 and 220 to facilitate the opening and closing operation.

In addition, the first and second doors 210 and 220 are provided with a door locking device 300 as shown in FIGS. 4 and 5 to prevent opening of the main body 100.

Hereinafter, the door locking device 300 will be described with reference to the drawings.

As shown in FIGS. 2 to 5, the door locking device 300 is coupled to the door handle 310 and the door handle 310 which are hinged to the front vertical direction of the first door 210. It is composed of a link 320 having a latch 321 and a support bracket 330 in which a latch 331 is formed to insert the latch 321.

Here, the door handle 310 is installed on the front outer side of the first door 210, the link 320 is mounted inside the first door 210, the latch 321 is the first It is installed to enter and exit the opening 121 of the door 210.
