Description

Handle structure of refrigerator door {STRUCTURE FOR DOOR HANDLE OF REFRIGERATOR}

The present invention relates to a handle structure of a refrigerator door. The present invention relates to a handle structure of a refrigerator door that prevents leakage of foam liquid filled in the door by changing the structure of the handle formed on the door of the refrigerator.

In general, the refrigerator is divided into a freezer compartment for storing ice-making containers and frozen foods at a set temperature, and a refrigerating compartment in which refrigeration objects are stored, and a refrigeration cycle device is installed therein and circulated in a refrigeration cycle of evaporation, compression, condensation, and expansion. In order to keep the inside frozen and refrigerated, by absorbing external heat from the evaporator in the circulation circuit.

1 to 3, the refrigerator is bisected by a main body 1 and a separating wall 15 integrated into the main body 1, and a freezer compartment 10 for freezing and storing food and refrigerated storage. A refrigerating chamber 20, a freezing chamber door 42 installed at the front of the main body 1 to open and close the freezing chamber 10, and a refrigerating chamber door 41 to open and close the refrigerating chamber 20, and the freezing chamber 10. And each temperature sensor 23 mounted in the refrigerator so as to sense a temperature inside the refrigerating compartment 20, and a plurality of shelves 22 capable of seating food in the refrigerating compartment 20 are mounted in multiple layers.

The freezer compartment door 42 has a door plate 43 and a door liner 44 coupled to each other, as shown in FIG. 3, which enlarges a portion of the freezer compartment door 42, and inserts the door plate 43. The steel plate insertion groove 46a and the handle connecting frame 45 to which the coupling groove 46b and the handle groove 46c formed with the handle groove 46c are mounted to form an inner space, and the handle frame 46 After the tape 47 is bonded and sealed to the engaging portion of the door plate 43, the foam 48, which is a heat insulating material, is filled in the inner space.

The handle structure of the refrigerating compartment door 41 also has the same structure as the freezer compartment door 42.

Refrigeration cycle 30 to create the cold air required for cooling the refrigerating chamber 10 and the freezing chamber 20 and the cold air provided by the freezing cycle 30 to the rear of the main body 1 to the freezing chamber 10 The blower 12 forcibly blown the air, the cold air guide passage 13 formed in the main body 1 to guide the cold air generated by the refrigerating cycle 30 to the refrigerating chamber 20, and integrated into the main body 1. The freezing chamber cold air circulation path 16 and the refrigerating compartment for cooling the freezer compartment 10 and the refrigerating compartment for guiding the cold air to cool again according to the continuous operation of the refrigerating cycle 30 are formed in the divided partition 15. Is configured as a cold air circulation path 17 for the refrigerating chamber to guide the cooling again according to the continuous operation of the refrigeration cycle (30).

In the refrigerating cycle 30 is installed at the rear lower end of the main body 1, the compressor 31 for compressing low-temperature, low-pressure gas refrigerant into high-temperature, high-pressure gas refrigerant and the high-temperature, high-pressure gas refrigerant A condenser 32 for converting a high pressure liquid refrigerant, a capillary tube 33 for converting the high temperature and high pressure liquid refrigerant into a low temperature, low pressure liquid refrigerant, and a rear of the freezing chamber 10 of the main body 1. And an evaporator 34 installed in the evaporator to evaporate the low temperature and low pressure liquid refrigerant to a low temperature and low pressure gas refrigerant.

In the conventional refrigerator configured as described above, in order to store fresh food stored in the freezer compartment 10 or on the shelf 22 mounted in multiple layers in the refrigerator compartment 20 for a long time, the refrigerator compartment door is supplied with power. The compressor 31 constituting the refrigerating cycle 30 is driven by receiving a control signal of a controller (not shown) mounted inside the 21 to compress a low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant. The compressed high-temperature, high-pressure gas refrigerant is condensed into a high-temperature, high-pressure liquid refrigerant while passing through the condenser 32.

The condensed high temperature and high pressure liquid refrigerant is converted into a low temperature and low pressure liquid refrigerant through a capillary tube 33, and the low temperature and low pressure liquid refrigerant is converted into a low temperature and low pressure gas refrigerant through an evaporator 34. As it is evaporated, the surrounding air is heat exchanged by the evaporation of the evaporator 34 to cool the surrounding air, thereby generating cold air.

Part of the cold air generated as described above is forcedly blown according to the rotation of the blower 12 installed at the rear of the main body 1, enters the freezing chamber 10, cools it to a predetermined temperature, and freezes food. Guided through the cold air flow path 13 formed in the entering the refrigerating chamber 20 to cool the refrigerating compartment 20 to a predetermined temperature so that food is refrigerated.

In this way, the cold air enters the freezing chamber 10 and the refrigerating chamber 20 to cool the freezing chamber 10 and the refrigerating chamber 20, and then, in accordance with the continuous operation of the refrigerating cycle 30, the cold air of the freezing chamber is stored in the main body 1. Guided to the evaporator 34 through the cold air circulation path 16 for the freezing chamber 10 formed in the partition wall 15 of the cooling wall 10 to continuously generate cold air by the evaporation action, and the cold air in the refrigerator compartment 20 Is led to the evaporator 34 through the cold air circulation path 17 for the refrigerating chamber 20 formed in the separation wall 15 of

However, the handle structure of the conventional refrigerator door is assembled by the door plate 43 to the handle frame 46, the tape 47 is bonded and sealed, and then filled with the foam material 48, the tape There is a problem that the number of working hours for sealing the 47 increases, and the foam member 48 leaks into the gap where the tape 47 adheres to the tape 47, resulting in poor assembly of the door.

An object of the present invention devised in view of the above point is to provide a handle structure of the refrigerator door that can prevent the leakage of the foam material filled in the door by improving the handle structure of the refrigerator door.
