Abstract

A refrigerator includes a main body cabinet having a first storage room and a second storage room to be divided with the first storage room and respectively cooled, an evaporator having a first evaporating part disposed at the main body cabinet and cooling the first storage room, a second evaporating part disposed at the main body cabinet to be apart from the first evaporating part and cooling the second storage room, and a refrigerant moving pipe connecting the first and second evaporating parts, and a duct guiding cooling air generated by the first and second evaporating parts to the first and second storage rooms to respectively cool the first and second storage rooms, the first and second evaporating parts and the refrigerant moving pipe are formed with one evaporating pipe. The refrigerator forms integrally an evaporator for cooling a first storage room and a second storage room respectively.

Claims

1. A refrigerator, comprising:

a main body cabinet having a first storage room and a second storage room to be divided with the first storage room and respectively cooled;

an evaporator having a first evaporating part disposed at the main body cabinet and cooling the first storage room, a second evaporating part disposed at the main body cabinet to be apart from the first evaporating part and cooling the second storage room, and a refrigerant moving pipe connecting the first and second evaporating parts; and

a duct for guiding cooling air generated by the first and second evaporating parts to the first and second storage rooms to respectively cool the first and second storage rooms,

wherein the first and second evaporating parts and the refrigerant moving pipe are formed with one evaporating pipe.

2. The refrigerator according to claim 1, wherein the refrigerant moving pipe comprises:

a first refrigerant moving pipe provided between the first and second evaporating parts so that the refrigerant passing through one area of the first evaporating part is transferred to the second evaporating part; and

a second refrigerant moving pipe provided between the first and second evaporating parts so that the refrigerant passing through the second evaporating part from the first refrigerant moving pipe is transferred to the other area of the first evaporating part.

3. The refrigerator according to claim 2, further comprising:

a separating partition detachably coupled with the main body cabinet to divide between the first and second storage rooms.

4. The refrigerator according to claim 3, wherein the duct comprises a first duct disposed at the main body cabinet and forming a cooling air pathway of the first evaporating part, and a second duct disposed at the main body cabinet and forming a cooling air pathway of the second evaporating part;

and

the separating partition is coupled with at least one of the first duct and the second duct.

5. The refrigerator according to claim 4, further comprising:

a coupling part supporting a rear end part of the separating partition on a central area of the first and second ducts, and wherein the first duct is integrally provided with the second duct.

6. The refrigerator according to claim 5, further comprising a seating part provided in a front area of the main body cabinet and placed between the first and second storage rooms to support a front end part of the separating partition.

7. The refrigerator according to claim 1, further comprising a separating tray provided in a space between the first and second evaporating parts to prevent the cooling air generated from the first and second evaporating parts from being mixed each other.

8. The refrigerator according to claim 7, further comprising:

a defrost heater for defrosting the first evaporating part, and wherein the separating partition receives defrost water defrosted by the defrost heater.

9. The refrigerator according to claim 4, wherein the first and second storage rooms are divided in the main body cabinet in a vertical direction by the separating partition.

10. A manufacturing method of a refrigerator having a first storage room and a second storage room to be divided with the first storage room and respectively cooled, the method comprising:

providing an evaporator having a first evaporating part and a second evaporating part to be apart from each other to respectively cool the first and second storage rooms, and a refrigerant moving pipe connecting the first and second evaporating parts;

providing a separating partition detachably coupled with the main body cabinet to divide between the first and second storage rooms;

disposing the evaporator at the main body cabinet so that the first and second evaporating parts correspond to the first and second storage rooms in a state that the separating partition is separated from the main body cabinet; and

disposing the separating partition at the main body cabinet to divide between the first and second storage rooms.

11. The manufacturing method according to claim 10, wherein the first evaporating part and the second evaporating part, and the refrigerant moving pipe are formed with one evaporating pipe without joints.

12. The manufacturing method according to claim 10, further comprising disposing a separating tray at a space of the first and second evaporating parts to prevent cooling air generated from the first and second evaporating parts from being mixed each other.

13. The manufacturing method according to claim 12, further comprising:

providing a duct detachably coupled inside the first and second storage rooms; and

disposing the duct at the main body cabinet so that the duct is mounted to a front of the evaporator.

14. The manufacturing method according to claim 13, further comprising providing a coupling part supporting a rear end part of the separating partition on the duct.

15. The manufacturing method according to claim 14, further comprising providing a seating part in a front area of the main body cabinet placed between the first and second storage rooms to support the front end part of the separating partition.

16. A refrigerator comprising:

a first storage room and a second storage room to respectively store food therein;

a first evaporator and a second evaporator to supply cooling air for the first storage room and the second storage room, respectively;

a separating tray positioned between the first evaporator and the second evaporator to separate the cooling air supplied to the first storage room and the second storage room, respectively.

17. The refrigerator of claim 16, further comprising:

a refrigerant moving pipe to connect the first evaporator and the second evaporator to each other, and to flow refrigerant therebetween.

18. The refrigerator of claim 16, wherein the first storage room and the second storage room are divided in a vertical direction.

19. The refrigerator of claim 17, further comprising a first duct and a second duct corresponding to the first storage room and the second storage room, respectively, to supply the cooling air supplied from the first evaporator and the second evaporator into the first storage room and the second storage room, respectively.

20. The refrigerator of claim 19, wherein the first duct and the second duct are integrally formed together.

21. The refrigerator of claim 19, further comprising a separating partition to divide the first storage room from the second storage room, wherein the separating partition is detachably coupled with the first and the second duct.
