Abstract

A refrigerator with a reserved installation space arranged in a bottom heat dissipation compartment includes a cabinet with a heat dissipation compartment set at its rear bottom; a compressor, a duct assembly, and an evaporating tray sequentially arranged within the heat dissipation compartment along a horizontal direction of the cabinet, and the heat dissipation compartment reserves an installation space on one side away from the duct assembly relative to the evaporating tray, the installation space is equipped with one or more mating structures, each of which is used to install an auxiliary functional component. This design optimizes the layout of devices within the confined space of the heat dissipation compartment to fulfill the purpose of reserving installation space. This provides installation space for expanding the functionality of different refrigerator models, enhancing product competitiveness and saving development costs.

Claims (44)

1 . A refrigerator, comprising:

a cabinet defining a storage chamber, with a heat dissipation compartment set at a rear bottom of the cabinet;

a compressor, a duct assembly, and an evaporating tray sequentially arranged within the heat dissipation compartment along a horizontal direction of the cabinet, wherein a heat dissipating fan is installed on a first side of the duct assembly facing the compressor, a condenser is installed on a second side of the duct assembly facing the evaporating tray, and

the heat dissipation compartment reserves an installation space on a third side of the evaporating tray away from the duct assembly, the installation space is equipped with one or more mating structures, each of which is used to install an auxiliary functional component;

the mating structures comprise a first mating structure set on a bottom plate of the heat dissipation compartment, the first mating structure comprises multiple fixing holes and fixing columns corresponding one-to-one with the fixing holes; and

the auxiliary functional component mounted on the first mating structure comprises a vacuum pump, which is mounted on the fixing columns.

2 . The refrigerator of claim 1 , wherein

a length of the installation space along the horizontal direction of the refrigerator is greater than or equal to 10% of a length of the heat dissipation compartment along the horizontal direction of the refrigerator.

3 . The refrigerator of claim 2 , wherein

the mating structures comprise a second mating structure set on a sidewall of the installation space opposite the duct assembly.

4 . The refrigerator of claim 3 , wherein

the bottom plate of the heat dissipation compartment on a fourth side opposite the compressor relative to the duct assembly is equipped with a first roller; the bottom plate of the heat dissipation compartment is equipped with a second roller; the first mating structure surrounds the second roller.

5 . The refrigerator of claim 3 , wherein

the second mating structure comprises a positioning slot and fixing holes located on the sidewall of the installation space;

the auxiliary functional component mounted on the second mating structure comprises an ice water valve, which is connected to the second mating structure through a fixed frame.

6 . The refrigerator of claim 5 , wherein

the fixed frame is configured to position the ice water valve in a center of the installation space, maintaining specified distances from the sidewall of the installation space opposite the duct assembly, a top wall, and a bottom wall of the installation space, and the evaporating tray.

7 . The refrigerator of claim 1 , wherein

heights of the fixing columns are configured such that a first height from a bottom of the second roller to the bottom plate of the heat dissipation compartment is less than a second height from a top of the second roller to a bottom of the vacuum pump.

8 . The refrigerator of claim 7 , wherein

a top of the vacuum pump is spaced at a gap from a top wall of the installation space.

9 . The refrigerator of claim 8 , wherein

a horizontal distance from the evaporating tray to a side wall of the vacuum pump is less than a horizontal distance from the vacuum pump to the sidewall of the installation space opposite the duct assembly.

10 . The refrigerator of claim 7 , wherein

a horizontal distance from the evaporating tray to a side wall of the vacuum pump is less than a horizontal distance from the vacuum pump to the sidewall of the installation space opposite the duct assembly.

11 . The refrigerator of claim 1 , wherein

a horizontal distance from the evaporating tray to a side wall of the vacuum pump is less than a horizontal distance from the vacuum pump to the sidewall of the installation space.

12 . A refrigerator, comprising:

a compressor, a duct assembly, and an evaporating tray sequentially arranged within the heat dissipation compartment along a horizontal direction of the cabinet, wherein a heat dissipating fan is installed on a first side of the duct assembly facing the compressor, a condenser is installed on a second side of the duct assembly facing the evaporating tray, and

the heat dissipation compartment reserves an installation space on a third side of the evaporating tray away from the duct assembly, the installation space is equipped with one or more mating structures, each of which is used to install an auxiliary functional component;

the mating structures comprise a first mating structure set on a sidewall of the installation space opposite the duct assembly, the first mating structure comprises a positioning slot and fixing holes located on the sidewall of the installation space opposite the duct assembly;

the auxiliary functional component mounted on the first mating structure comprises an ice water valve, which is connected to the first mating structure through a fixed frame.

13 . The refrigerator of claim 12 , wherein

the mating structures comprise a second mating structure set on a bottom plate of the installation space.

14 . The refrigerator of claim 13 , wherein

the bottom plate of the heat dissipation compartment on one side opposite the compressor relative to the duct assembly is equipped with a first roller; the bottom plate of the heat dissipation compartment is equipped with a second roller; the second mating structure surrounds the second roller.

15 . The refrigerator of claim 14 , wherein

the second mating structure comprises multiple fixing holes and fixing columns corresponding one-to-one with the fixing holes; and

the auxiliary functional component mounted on the second mating structure comprises a vacuum pump, which is mounted on the fixing columns.

16 . The refrigerator of claim 14 , wherein

a horizontal distance from the evaporating tray to a side wall of the vacuum pump is less than a horizontal distance from the vacuum pump to the sidewall of the installation space opposite the duct assembly.

17 . The refrigerator of claim 13 , wherein
