## Abstract

A refrigerator includes a cabinet, in which a cooling chamber and at least one storage space are defined, the cooling chamber being arranged at the bottom of the cabinet and directly below the storage space; a door body, which is arranged on a front surface of the cabinet so as to operably open and close the storage space; an evaporator, which is wholly horizontally placed in the cooling chamber in the shape of a flat cube, and is configured to provide cooling capacity to the storage space; and a liquid storage bag, which is arranged in the cooling chamber and connected to the evaporator. An included angle between a center line of the liquid storage bag and a horizontal line is 1° to 89°. A foam layer and a housing of the refrigerator may block the sound transmission of flow of a liquid refrigerant, to achieve a good sound insulation effect.

## Claims

### Claim 1

A refrigerator, comprising
a cabinet defining a cooling chamber and at least one storage space therein, the cooling chamber being arranged at a bottom of the cabinet and directly below the storage space;
a door body arranged on a front surface of the cabinet so as to operably open and close the storage space;
an evaporator wholly horizontally arranged in the cooling chamber in the shape of a flat box and configured to provide cooling capacity for the storage space; and
an accumulator arranged in the cooling chamber and connected to the evaporator, an included angle between a center line of the accumulator and a horizontal line being 1° to 89°;
wherein there are a plurality of storage spaces including a refrigeration space and at least one freezing space, and the cabinet comprises a freezing liner, the cooling chamber and the at least one freezing space located above the cooling chamber being defined in the freezing liner;
wherein the refrigerator further comprises a refrigerating fan arranged behind the evaporator,
wherein the accumulator is arranged in a space enclosed by the refrigerating fan, the evaporator and a right side of the freezing liner; or
the accumulator is arranged in a space enclosed by the refrigerating fan, the evaporator and a left side of the freezing liner; or
the accumulator is arranged between the evaporator and the right side of the freezing liner; or
the accumulator is arranged between the evaporator and the left side of the freezing liner; or
the accumulator is arranged between the evaporator and the refrigerating fan.

### Claim 2 (depends on 1)

The refrigerator according to claim 1, wherein
the cabinet further comprises a refrigeration liner arranged just above the freezing liner, the refrigeration space being defined in the refrigeration liner.

### Claim 3 (depends on 2)

The refrigerator according to claim 2, further comprising
an air supply duct arranged on inner sides of rear walls of the refrigeration liner and the freezing liner, an air supply inlet in communication with the cooling chamber being formed in a bottom end of the air supply duct, and air supply outlets being formed in the positions corresponding to the refrigeration space and the freezing space, so as to transmit the cooling capacity provided by the evaporator to the storage spaces.

### Claim 4 (depends on 3)

The refrigerator according to claim 3,
wherein an air blowing direction of the refrigerating fan directly faces the air supply inlet, so that the cooling capacity generated by the evaporator can enter the air supply duct.

### Claim 5 (depends on 1)

The refrigerator according to claim 1, wherein
the evaporator comprises an evaporator body, an upper cover plate and a lower cover plate,
wherein the evaporator body comprises a plurality of fins arranged in parallel and coil penetrating through the fins,
the upper cover plate is arranged at a top of the evaporator body, and
the lower cover plate is arranged at the bottom of the evaporator body.

### Claim 6 (depends on 5)

The refrigerator according to claim 5, wherein
notches are formed in corresponding positions of each fin, and passages laterally extending along the evaporator are formed by the notches in the corresponding positions; and
the refrigerator further comprises a heating wire embedded in the passages to defrost the evaporator.

### Claim 7 (depends on 5)

The refrigerator according to claim 5, wherein
first fixing holes are formed in four corners of the upper cover plate, and second fixing holes are correspondingly formed in four corners of the top of the evaporator body in position; and
third fixing holes are formed in four corners of the lower cover plate, and fourth fixing holes are correspondingly formed in four corners of the bottom of the evaporator body in position.

### Claim 8 (depends on 7)

The refrigerator according to claim 7, wherein
the evaporator further comprises fixing members configured to pass through the aligned first fixing holes and second fixing holes to fix the upper cover plate and the evaporator body, and pass through the aligned third fixing holes and fourth fixing holes to fix the lower cover plate and the evaporator body.

### Claim 9 (depends on 8)

The refrigerator according to claim 8, wherein
the first fixing holes and the third fixing holes are kidney-shaped holes, and
the second fixing holes and the fourth fixing holes are circular holes.
