Detailed ways

This embodiment provides a refrigerator 100 , and the refrigerator 100 according to the embodiment of the present invention will be described below with reference to FIGS. 2 to 4 . In the following description, the orientations or positional relationships indicated by "front", "rear", "upper", "lower", "left", "right", etc. are orientations based on the refrigerator 100 itself as a reference. “Rear” is the direction indicated in FIGS. 2 and 3 . As shown in FIG. 4 , “horizontal” also refers to the left-right direction, and refers to the direction parallel to the width direction of the refrigerator 100 .

As shown in FIGS. 1 to 4 , the refrigerator 100 generally includes an outer shell 110 and a storage inner pot 130 disposed inside the outer shell 110 , and the space between the outer shell 110 and the storage inner pot 130 is filled with a thermal insulation material (forming a hair dryer). bubble layer), at least one storage compartment 131 is defined in the storage liner 130 .

As shown in FIG. 1 , in the prior art, the evaporator 101 and the blower 103 of the refrigerator 100 are all disposed at the rear of the storage compartment 131 , occupying the space behind the storage compartment 131 , so that the The reduction in depth results in a reduction in the depth of the storage container 133 placed in the storage compartment 131 , which makes it inconvenient to place items that are long and difficult to be divided.

In this embodiment, a lateral side wall of the storage compartment 131 defines an air duct chamber, the evaporator 101 is arranged in the air duct chamber, and is configured to cool the airflow entering the air duct chamber, and the blower 103 is arranged in the air duct chamber. Inside the duct chamber, and located in front of the evaporator 101 , is configured to cause at least part of the airflow cooled by the evaporator 101 to flow through the duct chamber to the at least one storage compartment 131 . This avoids the problem that the evaporator 101 occupies the rear space of the storage compartment 131, which leads to the reduction of the depth of the storage compartment 131, and fully utilizes the space of the lateral side wall of the storage compartment 131, which is originally an invalid volume. The volume utilization rate of the refrigerator 100 is improved.

In one of the embodiments, the storage inner liner 130 is divided into two horizontally distributed storage compartments 131 by the vertical partition plate 134 , that is, the storage inner tank 130 is divided by the vertical partition plate 134 There are two left and right storage compartments 131 , and each storage compartment 131 may be provided with a plurality of storage containers 133 distributed up and down, and the storage containers 133 may generally be storage drawers with an open top.

The vertical partition plate 134 constitutes a lateral side wall of the storage compartment 131 , the vertical partition plate 134 can define the aforementioned air duct chamber, thereby making full use of the space of the vertical partition plate 134 , and it is convenient to use the air duct chambers of the vertical partition plate 134 to supply air to the two storage compartments 131 on the two lateral sides respectively.

In an alternative embodiment, since the lateral side wall of the storage inner pot 130 constitutes one lateral side wall of the storage compartment 131 , the aforementioned air duct cavity may be defined in the lateral side wall of the storage inner pot 130 . room.

As shown in FIG. 2 , an evaporator chamber 1341 is defined in the vertical partition plate 134, and the evaporator 101 is vertically arranged in the evaporator chamber 1341 in a plate shape, that is, the long surface of the evaporator 101 is perpendicular to the horizontal plane, and the width The surface and the thickness surface are parallel to the horizontal plane, and the dimension of the long surface of the evaporator 101 is significantly larger than the dimension of the thickness surface, which can match the vertical partition plate 134 and increase the heat exchange area of the evaporator 101 as much as possible.

The refrigerator 100 further includes two door bodies 132 , which are disposed laterally opposite to the front side of the storage tank 130 to form a side door to open and close the two storage compartments 131 respectively.

At least one left air supply port 134a is formed on the side of the vertical partition plate 134 facing the lateral left side, and the left air supply port 134a communicates with the storage compartment 131 located on the lateral left side, so that the airflow after cooling of the evaporator 101 passes through the air duct The chamber and the left air supply port 134a are blown into the storage compartment 131 on the left side. Correspondingly, at least one right air supply port 134b is formed on the side of the vertical partition plate 134 facing the lateral right side, and the right air supply port 134b communicates with the storage compartment 131 located on the lateral right side, so as to cool the air flow of the evaporator 101 The air is blown into the storage compartment 131 on the right side through the air duct chamber and the right air supply port 134b.

The side of the vertical partition plate facing the left side in the horizontal direction can be formed with a plurality of left air supply ports 134a distributed at intervals up and down.
