This is only to facilitate the description of the present invention and simplify the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

Referring to Figures 1 and 2, Figure 1 is a schematic diagram of the refrigerator 1 according to an embodiment of the present invention, and Figure 2 is a schematic diagram of the box 10 of the refrigerator 1 according to an embodiment of the present invention, in which the outer shell is hidden in Figure 2.

The present invention provides a refrigerator 1, which generally includes a box body 10 and a door body 20. The box body 10 may include an outer shell and a plurality of inner pots. The outer shell is located at the outermost side of the entire refrigerator 1 to protect the entire refrigerator 1 . Multiple inner bladders are wrapped by the outer shell, and the spaces between the multiple inner bladders and the outer shell are filled with thermal insulation material (forming a foam layer) to reduce the outward heat dissipation of the inner bladders. Each inner bag can define a storage space that opens forward, and the storage space can be configured as a refrigerator, a freezer, a changing room, etc. The specific number and functions of the storage spaces can be configured according to pre-existing needs.

In some specific embodiments, the number of the inner bladders can also be set to two. The two inner bladders are the first inner bladder 120 and the second inner bladder 130 respectively. The two inner bladders can be arranged side by side and have different functions. Storage compartments, for example, the first compartment 122 of the first inner bladder 120 can be configured as a freezer compartment, and the second compartment 132 of the second inner bladder 130 can be configured as a refrigerating compartment. Generally, the first compartment 122 of the first compartment 122 can be configured as a freezer compartment. The temperature is lower than the temperature of the second chamber 132.

The number of doors 20 can also be consistent with the number of inner containers, that is, each storage compartment with the inner container opening forward can be opened and closed by its corresponding door 20 . The door 20 is movably disposed in front of the box 10. For example, the door 20 can be hingedly disposed on one side of the front of the box 10, and can open and close the storage space in a pivoting manner. In particular, for the refrigerator 1 having the first inner pot 120 and the second inner pot 130 arranged side by side, the two door bodies 20 can also be arranged side by side, that is, it is a side-by-side door refrigerator.

The storage room is provided with cooling capacity by the refrigeration system to achieve a refrigerated, frozen, and variable-temperature storage environment. The refrigeration system may be a refrigeration cycle system composed of a compressor, a condenser, a throttling device, an evaporator 30, and the like. The evaporator 30 is configured to provide cooling energy directly or indirectly to the storage room interior. For example, in the compression air-cooled refrigerator 1, there is also a cooling chamber 124 in the box 10. The evaporator 30 chamber is connected to the storage room through the air duct system, and the evaporator 30 is installed in the evaporator 30 chamber, and the evaporator 30 is installed at the outlet. An air supply fan 40 is provided to circulate refrigeration to the storage room.

Referring to Figures 3 to 5, Figure 3 is an exploded view of the box 10 in the refrigerator 1 according to one embodiment of the present invention. Figure 4 is a rear view of the box 10 in the refrigerator 1 according to one embodiment of the present invention. Figure 5 is A schematic cross-sectional view taken along section line A-A in Figure 4, where the dotted arrow in Figure 5 represents the flow direction of the refrigerant airflow.

Specifically, the box 10 may further include a first air duct assembly 140 . The first air duct assembly 140 is disposed in front of the rear wall of the first liner 120 to divide the first liner 120 into a cooling chamber 124 for installing the evaporator 30 and a first chamber 122 located in front of the cooling chamber 124. The interior of the first air duct assembly 140 defines a first air duct 140a, and a plurality of first air outlets 149 for communicating the first air duct 140a and the first chamber 122 are formed on the first air duct assembly 140.

Since the temperature of the first chamber 122 is lower than that of the second chamber 132, arranging the evaporator 30 in the first inner bladder 120 can make the air flow path to the first chamber 122 shorter, thereby making the first The heat exchange in the compartment 122 is more complete and the temperature is lower.

The first air duct assembly 140 may include an upper air duct member 142 and a lower air duct member 144 that are fixedly connected up and down. The upwind channel member 142 and the downwind channel member 144 are both disposed in front of the rear wall of the first inner bladder 120 . The downwind channel member 144 may together with the rear wall of the first inner bladder 120 and the rear portions of both side walls of the first inner bladder 120 form a cooling chamber 124 for installing the evaporator 30 .

The upper air duct member 142 has a rear cover 142a and a front cover 142b arranged in front of the rear cover 142a. The rear cover 142a and the front cover 142b are interlocked and form a first air channel 140a. A fan cavity 143 for installing the air supply fan 40 is formed on the rear cover 142a, and a plurality of first air outlets 149 are provided on the front cover 142b.

In addition, the downwind channel member 144 extends downward to above the bottom wall of the first liner 120 and maintains a certain gap with the bottom wall of the first liner 120 to form a return air outlet 148 . In some further embodiments, the first air duct assembly 140 may include a return air duct member 146 formed at the bottom end of the downwind duct member 144 and spaced along the bottom wall of the first liner 120 The ground extends forward to form a refrigeration return air duct 146a connected with the return air outlet 148.

During cooling, the evaporator 30 exchanges heat with the air in the cooling chamber 124 to form a cooling air flow. The air supply fan 40 prompts this part of the cooling air flow to first enter the first air duct 140a, and then the cooling air flow flows through a plurality of first outlets. The air outlet 149 is discharged into the first chamber 122 through the first air duct 140a to exchange heat with the food in the first chamber 122. After the heat exchange is completed, this part of the refrigeration air flow can return to the cooling chamber 124 through the refrigeration return air duct 146a and the return air outlet 148 to form a circulating refrigeration air flow.

Furthermore, the refrigeration demand of the second room 132 can also be realized by the evaporator 30 disposed in the first liner 120 , that is, the side-by-side refrigerator 1 of this embodiment adopts a single-system refrigeration method.

Referring to Figures 3 and 6, Figure 6 is a schematic cross-sectional view taken along section line B-B in Figure 4, wherein the dotted arrow in Figure 6 represents the flow direction of the refrigerant airflow. Specifically, the box 10 may further include a second air duct assembly 150 . The second air duct assembly 150 is disposed in front of the rear wall of the second liner 130 to divide the second liner 130 into a second air duct 152 and a second chamber 132 located in front of the second air duct 152. A plurality of second air outlets 154 for communicating the second air duct 152 and the second chamber 132 are formed on the duct assembly 150 .

The second air duct assembly 150 may be in the shape of a flat plate as a whole, and is disposed substantially parallel to the rear wall of the second liner 130, with a second air duct 152 formed therebetween. Since the cooling capacity requirement of the second room 132 is small and no additional evaporator is required, the second air duct 152 can be provided with a smaller space, and the second air duct assembly 150 does not occupy the rear wall of the second inner bladder 130 This allows the second compartment 132 to obtain a larger storage space.

Referring to Figure 7, Figure 7 is a schematic diagram of the connection relationship between the first air duct assembly 140, the second air duct assembly 150 and the connecting air duct member 50 in the refrigerator 1 according to an embodiment of the present invention. The dotted arrows in Figure 7 represent refrigeration. The direction of air flow. The first air channel 140a can provide cooling airflow to the second air channel 152 through the connecting air channel member 50 (the connecting air channel member 50 will be described below). The cooling airflow entering the second air channel 152 is discharged into the second chamber 132 through the plurality of second air outlets 154, and exchanges heat with the food in the second chamber 132. A refrigeration return air channel 136 (shown in Figure 6) can be provided between the side walls of the first compartment 122 and the second compartment 132 that are close to each other. The refrigeration airflow after heat exchange can be discharged into the first compartment through the refrigeration return air channel. 122, and then enters the refrigeration return air duct 146a to form a circulating air flow.

Referring to Figures 8 to 10, Figure 8 is an exploded view of the connecting vent 50 and the damper assembly in the refrigerator 1 according to one embodiment of the present invention. Figure 9 is an exploded view of the connecting vent 50 in the refrigerator 1 according to one embodiment of the present invention. 10 is a schematic cross-sectional view taken along the section line C-C in FIG. 9 , where the solid arrow in FIG. 10 represents the flow path of the water droplets.

The connecting air channel 50 has a connecting air channel 510. The connecting air channel 50 communicates with the first air channel 140a and the second air channel 152 to allow at least part of the cooling air flow in the first air channel 140a to flow into the second air channel through the communicating channel 510. Wind channel 152.

A damper assembly is provided in the communication channel 510, and the damper assembly can selectively open and close the communication channel 510. When the temperature of the second chamber 132 requires cooling air flow, the damper assembly can open When the connecting air channel 510 is opened, the cooling air flow in the first air channel 140a can enter the second air channel 152 along the connecting air channel 510, and then the plurality of second air outlets 154 can supply cold air to the second room 132. When the temperature of the second room 132 reaches the preset target temperature, the damper assembly can close the communication channel 510 to block the cooling air flow entering the second air channel 152 .

Since the damper assembly is disposed in the connecting vent 50, there is no need to design an installation space for the damper assembly for the first liner 120 and the second liner 130, thereby making the space of the first chamber 122 and the second chamber 132 more efficient. Regular and beautiful, and able to obtain larger storage volume.

The damper assembly may also include a damper frame 610 and a rotating plate 620 . The damper frame 610 can be installed on the communication channel 510, and has a flow hole 612 for passing the cooling air flow. The rotating plate 620 is pivotally connected to the damper frame 610 to open and close the flow hole 612 . That is, the rotating plate 620 can be opened and closed by flipping.

The direction of the flow hole 612 of the damper frame 610 and the communication channel 510 are substantially the same. When the rotating plate 620 is flipped to the open position where the through-flow hole 612 is opened, the cooling airflow in the communication channel 510 can be discharged to the second air channel 152 after passing through the through-flow hole 612 . When the rotating plate 620 is flipped to the closed position to close the through-flow hole 612, the cooling air flow in the communication channel 510 cannot pass through the through-flow hole 612, that is, the communication channel 510 is blocked.

The rotating plate 620 may be driven by a driving motor (not shown in the figure), which may be a stepper motor. Before the refrigerator 1 leaves the factory, the stepper motor can be configured with at least two extreme angular displacements to correspond to the closed position and the open position of rotation.

In addition, the stepper motor can also be configured with multiple adjustment angle displacements, so that the rotating plate 620 can be flipped to an adjustment position between the closed position and the open position, so as to adjust the flow through the flow hole 612 on the basis of opening the communication channel 510 of air flow. Those skilled in the art can specifically configure the adjustment angular displacement of the stepper motor according to actual conditions.

Referring to FIG. 10 , further, the damper frame 610 is arranged to be inclined from bottom to top in a direction close to the second inner bladder 130 . The rotating plate 620 is located on the side of the damper frame 610 facing the second liner 130 , and the pivot axis 622 of the rotating plate 620 is arranged to extend along the height direction of the damper frame 610 so that the condensed water on the rotating plate 620 is discharged to the second air duct. 152.

Due to the low temperature of the cooling air flow, water vapor in the air is easily condensed into liquid water vapor. When the refrigeration airflow carrying liquid water vapor flows in the connecting duct 510, the liquid water vapor gathers to form water droplets when it encounters the air duct wall of the connecting duct 510, the damper frame 610 and the rotating plate 620. Once these water droplets cannot be cleaned for a long time May lead to frost, the harmful effects of frost here are many. For example, later cleaning of frost requires disassembly of the machine and affects the ventilation surface of the connecting duct 510. accumulation, causing the rotating plate 620 to be unable to rotate normally, affecting the air tightness between the rotating plate 620 and the through-flow hole 612, etc.

In this embodiment, the damper frame 610 is arranged to tilt from bottom to top in a direction close to the second inner bag 130 , and the pivot axis 622 of the rotating plate 620 is arranged to extend along the height direction of the damper frame 610 , so that the rotating plate 620 also An angle θ is formed with the vertical direction, so the liquid water vapor accumulated on the rotating plate 620 and the damper frame 610 can be discharged to the inclined downstream in time to avoid frost on the rotating plate 620 and the damper frame 610 .

And because the damper frame 610 and the rotating plate 620 are tilted from bottom to top and in the direction close to the second inner bag 130, the rotating plate 620 is located on the side of the damper frame 610 facing the second inner bag 130. Therefore, the damper frame 610 and the rotating plate The inclined downstream of 620 is the second inner tank 130, so that the liquid water vapor discharged from the damper frame 610 and the rotating plate 620 can be discharged into the second inner tank 130. The temperature of the second inner tank 130 is higher than the temperature of the first inner tank 120, so the liquid water vapor discharged into the second inner tank 130 is more likely to evaporate.

Referring to FIG. 10 , further, the damper assembly may further include a heating wire 630 . The heating wire 630 is wound around the surface of the rotating plate 620 and/or the inside of the rotating plate 620 to heat and defrost the rotating plate 620 .

One way is that the heating wire 630 is coiled on the surface of the rotating plate 620 in an S shape. Preferably, heating wires 630 can be provided on both sides of the rotating plate 620 to ensure that the surface thereof will not be frosted. Another way is to directly arrange the heating wire 630 inside the rotating plate 620 when making it. These two methods can be used alternatively or at the same time.

In some embodiments, the connecting air duct member 50 may further include an air inlet section 520 close to the first liner 120 and an air outlet section 530 formed in the air inlet section 520 and extending toward the second liner 130 . The inlet of the air inlet section 520 serves as the inlet of the communicating air duct member 50 and is connected with the first air duct 140 a. The outlet of the air outlet section 530 serves as the outlet of the communicating air duct member 50 and is connected with the second air channel 152 .

In the front-rear direction, the air outlet section 530 is configured to be flatter than the air inlet section 520 . In the height direction, when the size of the air outlet section 530 and the air inlet section 520 are not much different, the air outlet section 530 is flatter than the air inlet section 520 , that is, the ventilation area of the air outlet section 530 is larger than that of the air inlet section 520 The ventilation area is smaller, so that when the cooling airflow flows from the air inlet section 520 to the air outlet section 530, the flow rate of the cooling airflow increases and the flow effect is better.

Referring to Figure 11, Figure 11 is a top view of the box 10 in the refrigerator 1 according to one embodiment of the present invention, which shows the positions of the first inner pot 120, the second inner pot 130 and the connecting vent 50 in the front and rear directions. relation. Since the air inlet section 520 is connected to the first liner 120, compared to the second liner 130, the inside of the first liner 120 needs to be divided into a cooling chamber with wider dimensions in the front and rear directions. 124, and the second liner 130 does not need to design a cooling chamber, so the second air duct 152 can be set flatter to provide the second chamber 132 with a larger storage space.

In order to adapt to this structure, the air outlet section 530 is connected to the rear position of the air inlet section 520 in the front and rear direction, so that the docking position of the air outlet section 530 and the second liner 130 can be at the second air duct 152 , so as not to cause the second air duct 152 to protrude forward or backward, affecting the aesthetics and spatial size of the second compartment 132.

The air door frame 610 is installed on the air inlet section 520. The air inlet section 520 has a top wall plate 522. The top wall plate 522 includes a horizontal plate section 522a close to the first inner bladder 120 and an inclined plate section 522b formed on the horizontal plate section 522a and extending toward the second inner bladder 130 and downwards. . The damper assembly may further include an abutment block 640 formed on the top of the damper frame 610. The top surface of the abutment block 640 is in contact with the inner wall of the inclined plate section 522b to keep the damper frame 610 from bottom to top. A tilted posture that is tilted in a direction closer to the second inner bladder 130 .

The cross-sectional shape of the air inlet section 520 can be substantially square, and the top wall plate 522 of the air inlet section 520 is composed of horizontal plate sections 522a and inclined plate sections 522b that are connected in the direction from the first inner pot 120 to the second inner pot 130 .

The damper frame 610 is installed in the air inlet section 520, specifically at a corresponding position below the inclined plate section 522b. The top surface of the abutting block 640 may be disposed consistent with the inclination direction of the damper frame 610 . Since the inclined plate section 522b extends downward toward the second inner bag 130, when the top surface of the abutting block 640 is in contact with the inner wall of the inclined plate section 522b, the abutting block 640, the damper frame 610 and the rotating plate 620 It is restricted to tilt from bottom to top toward the second inner tank 130 and downward to form an tilt angle to facilitate the discharge of liquid water vapor.

The air inlet section 520 also has an air inlet bottom wall plate 524 arranged opposite to the top wall plate 522. The air inlet bottom wall plate 524 is arranged to be inclined downward from the first inner bag 120 to the second inner bag 130 to rotate the rotor. The condensed water on the plate 620 is guided to the air outlet section 530 , and then directed to the second air channel 152 from the air outlet section 530 .

The air inlet bottom wall panel 524 slopes downward from the first liner 120 to the second liner 130. The liquid water droplets formed on the air door assembly can be discharged to the surface of the air inlet bottom wall panel 524, and then along the air inlet bottom. The wall plate 524 flows into the air outlet section 530 and finally stays in the second air duct 152 and evaporates in the second air duct 152 .

The air outlet section 530 has an air outlet bottom wall plate 532. The air outlet bottom wall plate 532 is formed on the air inlet bottom wall plate 524 and extends obliquely downward toward the second inner bladder 130. The wind base siding 524 slopes further downward.

The air inlet bottom wall panel 524 is connected to the air outlet bottom wall panel 532. Since the air outlet bottom wall panel 532 is set to slope more downward than the air inlet bottom wall panel 524, the slope of the air inlet bottom wall panel 524 is larger and more Facilitates the flow of liquid water droplets.
