In the description of the present embodiment, it is to be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "depth", and the like indicate orientations or positional relationships that are based on the orientation in a normal use state as a reference, and can be determined with reference to the orientations or positional relationships shown in the drawings, for example, "front" indicating the orientation means a side toward the user. This is merely to facilitate description of the invention and to simplify the description, and is not intended to indicate or imply that the device or element so referred to must be in a particular orientation, constructed and operated in a particular orientation, and thus should not be taken to be limiting of the invention.

Referring to fig. 1 and 2, fig. 1 is a front view of an air-cooled refrigerator 1 according to an embodiment of the present invention, in which a door 20 is hidden, and fig. 2 is a sectional view of the air-cooled refrigerator 1 according to an embodiment of the present invention. The invention provides an air-cooled refrigerator 1, and the air-cooled refrigerator 1 generally comprises a refrigerator body 10 and a door body 20.

The cabinet 10 may include an outer case 110 and a plurality of inner containers 100, and the outer case 110 is located at the outermost side of the overall refrigerator 1 to protect the entire refrigerator 1. The plurality of inner containers 100 are wrapped by the outer shell 110, and the space between the outer shell 110 and the inner containers 100 is filled with a thermal insulation material (forming a foaming layer 120) to reduce the heat dissipation of the inner containers 100 to the outside. Each of the inner containers 100 may define a storage compartment opened forward, and the storage compartments may be configured as a refrigerating compartment, a freezing compartment, a temperature changing compartment, and the like, and the number and functions of the specific storage compartments may be configured according to a predetermined requirement.

The door 20 is movably disposed in front of the inner container 100 to open and close the storage compartment of the inner container 100. For example, the door 20 may be hingedly disposed at one side of the front portion of the body 10 to pivotally open and close the storage compartment.

Furthermore, the air-cooled refrigerator 1 can also provide cold energy by a circulating refrigeration system so as to realize storage environments of refrigeration, freezing, temperature changing and the like. The circulating refrigerating system may be constituted by a compressor 182, a condenser, a throttling device, an evaporator 180, and the like.

The compressor 182 serves as a power source of the circulating refrigeration system, and increases the pressure and temperature of the refrigerant vapor by compression, thereby creating a condition for transferring the heat of the refrigerant vapor to the external environment medium, i.e., compressing the low-temperature and low-pressure refrigerant vapor to a high-temperature and high-pressure state, so that the refrigerant vapor can be condensed by using air or water at normal temperature as a cooling medium. The condenser takes away heat of the high-temperature and high-pressure refrigerant vapor from the compressor 182 by using the environment, so that the high-temperature and high-pressure refrigerant vapor is cooled and condensed into refrigerant liquid with high pressure and normal temperature. The throttling means is also a heat exchange device. The throttled low-temperature low-pressure refrigerant liquid is evaporated into steam in the refrigerant liquid. The evaporator 180 may be provided in the case 10 to provide cooling energy to the storage compartment of the refrigerator 1 in a manner of absorbing heat through evaporation.

Further, a partition beam 170 is disposed in one of the liners 100 in the box 10 along the front-rear direction and the vertical direction to divide the storage compartment of the liner 100 into two first compartments 101 and second compartments 102 arranged left and right. The first compartment 101 and the second compartment 102 may also be configured as different storage compartments. For example, the first compartment 101 is configured as a cold room, the second compartment 102 is configured as a variable temperature room, etc., to meet different cooling needs of users. Of course, the first compartment 101 and the second compartment 102 may also be configured as other storage compartments, which is not particularly limited in this embodiment.

Further, the cabinet 10 may further include an air duct plate 130, and the air duct plate 130 is disposed inside the inner container 100 to define an air supply duct 140 with a rear wall of the inner container 100, so that the air duct plate 130 may also serve as a rear wall of the first compartment 101 and the second compartment 102. The air duct plate 130 has a first air inlet 132 and a first air return 134 at a position corresponding to the first compartment 101, and a second air inlet 136 and a second air return 138 at a position corresponding to the second compartment 102. The cooling air flow in the air supply duct 140 can enter the first compartment 101 through the first air inlet 132 to exchange heat with the air in the first compartment 101, so as to cool the first compartment 101. The heat-exchanged air flow returns to the evaporator 180 through the first air return port 134 to form a circulating air flow. Similarly, the cooling airflow can cool the second compartment 102 through the second inlet 136 and the second outlet 138.

Referring to fig. 3 to 6, dashed arrows in fig. 3 to 6 indicate air flows. In some embodiments, the air-cooled refrigerator 1 may further include a damper 30. The damper 30 is rotatably disposed in the supply air duct 140, and the damper 30 has a first position, a second position, a third position, and a fourth position that are preset.

Referring to fig. 3, fig. 3 is a view showing the internal structure of the cabinet 10 in the air-cooled refrigerator 1 according to one embodiment of the present invention, which shows a state where the damper 30 is at the first position. When damper 30 is in the first position, it can open the airflow path of supply air duct 140 to first compartment 101 and block the airflow path of supply air duct 140 to second compartment 102. Therefore, the cooling air flow in the air supply duct 140 can completely enter the first compartment 101 from the first air inlet 132 to cool the first compartment 101.

For example, the first compartment 101 is configured as a cold compartment and the second compartment 102 is configured as a temperature-changing compartment. When the system detects that the temperature in the second compartment 102 has reached the predetermined temperature value of the user, the damper 30 may be adjusted to the first position, so that the damper 30 may block the airflow path from the air supply duct 140 to the second compartment 102, so that the second compartment 102 does not pass through the cooling airflow, and the cooling airflow generated by the circulating cooling system may completely enter the refrigerating compartment, so as to not only achieve accurate and rapid cooling of the first compartment 101, save energy, but also facilitate control of the temperature of the second compartment 102.

Referring to fig. 4, fig. 4 is a view showing the internal structure of the cabinet 10 in the air-cooled refrigerator 1 according to one embodiment of the present invention, in a state where the damper 30 is in the second position. When damper 30 is in the second position, it can simultaneously open the air flow path of supply duct 140 to first compartment 101 and the air flow path to second compartment 102. Therefore, the cooling air flow in the air supply duct 140 can enter the first compartment 101 and the second compartment 102 through the first air inlet 132 and the second air inlet 136 at the same time, so as to cool the first compartment 101 and the second compartment 102 at the same time.

Referring to fig. 5, fig. 5 is a view showing the internal structure of the cabinet 10 in the air-cooled refrigerator 1 according to one embodiment of the present invention, which shows a state where the damper 30 is at the third position. When damper 30 is in the third position, it may block both the airflow path to first compartment 101 and the airflow path to second compartment 102 of supply duct 140. In this way, neither of the refrigerant flows in the supply air duct 140 can enter the first compartment 101 and the second compartment 102.

Referring to fig. 6, fig. 6 is a view showing the internal structure of the cabinet 10 in the air-cooled refrigerator 1 according to one embodiment of the present invention, in a state where the damper 30 is in the fourth position. When damper 30 is in the fourth position, it may open the airflow path of supply air duct 140 to second compartment 102 and block the airflow path of supply air duct 140 to first compartment 101.

In the present embodiment, since the damper 30 is disposed in the air supply duct 140, and the air supply mode is switched by its own rotation, so as to realize the simultaneous guidance of the air flow path for supplying air to the first compartment 101 and the second compartment 102, the simultaneous interruption of the air flow path for supplying air to the first compartment 101 and the second compartment 102, the conduction of the air flow path for one of the first compartment 101 and the second compartment 102, and the interruption of the air flow path for the other compartment, there is no need for a plurality of mutually-fitted dampers, and the present invention has higher reliability, a small number of parts, and better economy.

Referring to fig. 3-6, in some embodiments, the case 10 further includes a first vertical divider 150, a second vertical divider 152, a first transverse divider 160, and a second transverse divider 162.

The first vertical partition 150 and the second vertical partition 152 are located on the same vertical axis to divide the air supply duct 140 into a first air duct 142 and a second air duct 144 which are arranged left and right, the first air duct 142 is used for supplying air to the first compartment 101, the second air duct 144 is used for supplying air to the second compartment 102, and an installation gap 154 is formed between the first vertical partition 150 and the second vertical partition 152.

The first transverse partition 160 and the second transverse partition 162 are located at the same horizontal line and are respectively located in the first air duct 142 and the second air duct 144, the opposite ends of the first transverse partition 160 and the second transverse partition 162 are located in the mounting gap 154, and the damper 30 is mounted in the mounting gap 154.

Specifically, the first vertical partition 150, the second vertical partition 152, the first transverse partition 160 and the second transverse partition 162 may be formed on the rear wall of the air duct plate 130 and extend from the periphery of the rear wall of the air duct plate 130 toward the center thereof, the first vertical partition 150 and the second vertical partition 152 are spaced apart to form a mounting gap 154, and the first transverse partition 160 and the second transverse partition 162 extend to both sides of the mounting gap 154, respectively, and are not connected. When the damper 30 is mounted at this mounting gap 154, switching of the air supply mode can be achieved in cooperation with the first vertical partition 150, the second vertical partition 152, the first lateral partition 160, and the second lateral partition 162.

Specifically, the damper 30 may include a main body section 310 and an extension section 320, the extension section 320 being formed in the middle of the main body section 310 and extending perpendicular to the main body section 310. Further, the pivot shaft of the damper 30 may be provided in the middle of the main body section 310 so as to effect rotation thereof.

Referring to fig. 3, when the damper 30 is in the first position, both ends of the main body section 310 are respectively engaged with the opposite end surfaces of the first and second

vertical partitions

150 and 152, and the ends of the extension section 320 are engaged with the ends of the second transverse partition 162 to block the second air path 144 with the extension section 320.

The first and second

vertical partitions

150 and 152 may have a lateral width such that ends thereof form end faces. When the damper 30 is at the first position, the two ends of the main section 310 respectively engage the opposite end surfaces of the first vertical partition 150 and the second vertical partition 152, the end of the extension section 320 respectively engages the end of the second transverse partition 162, so that the main section 310 blocks the installation gap 154 to separate the first air path 142 from the second air path 144, and the extension section 320 engages the second transverse partition 162 to block the second air path 144, so that the refrigerant air can only pass through the first air path 142 to the first compartment 101.

Referring to fig. 4, when the damper 30 is in the second position, both ends of the main section 310 are respectively engaged to the opposite end faces of the first vertical partition 150, and the extension section 320 avoids the first and second

lateral partitions

160 and 162. At this time, the main body section 310 blocks the installation gap 154 to separate the first air path 142 from the second air path 144, the extension section 320 avoids the first transverse partition 160 and the second transverse partition 162, and the first air path 142 and the second air path 144 are kept in an open state, so that the first air path 142 supplies air to the first compartment 101 and the second air path 144 supplies air to the second compartment 102.

Referring to fig. 5, the second vertical partition 152 is disposed above the first vertical partition 150. When the damper 30 is in the third position, the two ends of the main section 310 respectively engage with the ends of the first and second

transverse partitions

160 and 162, and the end of the extension section 320 engages with the end of the first vertical partition 150, so that the left section of the main section 310 abuts with the first transverse partition 160, the right section of the main section 310 abuts with the second transverse partition 162, and the end of the extension section 320 engages with the end of the first vertical partition 150 to block the first air duct 142 and the second air duct 144, i.e., to block the air flow path of the supply air duct 140 to the first compartment 101 and the air flow path to the second compartment 102 at the same time.

Referring to fig. 6, when the damper 30 is in the fourth position, both ends of the main body section 310 are respectively engaged with the opposite end surfaces of the first and second

vertical partitions

150 and 152, and the end of the extension section 320 is engaged with the end of the first transverse partition 160 to block the first air duct 142 with the extension section 320. The main section 310 thus blocks the mounting gap 154 and thus separates the first air chute 142 from the second air chute 144, and the extension section 320 interfaces with the first transverse partition 160 and blocks the first air chute 142 so that refrigerant air flow is only from the second air chute 144 to the second compartment 102.

Referring to fig. 2 to 7, fig. 7 is a view showing an internal structure of the cabinet 10 in the air-cooled refrigerator 1 according to one embodiment of the present invention, which shows a state where the damper 30 is at a fifth position. In some embodiments, the cabinet 10 further defines a cooling chamber 190 for disposing the evaporator 180, and the cooling chamber 190 is located below the supply air duct 140. The first vertical partition 150 is disposed above the cooling compartment 190, the second vertical partition 152 is disposed above the first vertical partition 150, and the first vertical partition 150 has a return air passage 150a penetrating the cooling compartment 190 therein.

Referring to fig. 7, the dashed arrows in fig. 7 indicate airflow. The damper 30 further has a predetermined fifth position in which both ends of the main section 310 are respectively engaged with the ends of the first and second

transverse partitions

160 and 162, and the extension section 320 is engaged with the end surface of the second vertical partition 152 to block the first and

second air paths

142 and 144 and expose the opening of the return air path 150a, so that the air flows in the first and

second air paths

142 and 144 through the return air path 150a into the cooling compartment 190.

In the present embodiment, when the damper 30 is in the fifth position, the main body section 310 can block the upper and lower portions of the first air path 142 and the upper and lower portions of the second air path 144. At this time, neither the first air duct 142 nor the second air duct 144 supplies air to the first compartment 101 and the second compartment 102, i.e., the air flow paths of the first air duct 142 and the second air duct 144 are blocked.

In general, when the first air path 142 and the second air path 144 are blocked by the damper 30, the refrigeration cycle is stopped and the temperature of the cooling compartment 190 is high relative to the cooling period.

When the damper 30 is rotated to the fifth position, the circulation refrigeration system of the refrigerator 1 stops operating. Since the extension portion 320 is engaged with the end surface of the second vertical partition 152, the opening of the return air channel 150a of the first vertical partition 150 is exposed, and the air below the first air duct 142 (which is at a relatively high temperature) returns to the cooling compartment 190 from the opening of the return air channel 150a to exchange heat with the evaporator 180, so that the evaporator 180 can be heated by the air at a relatively high temperature to defrost the evaporator 180, thereby preventing the evaporator 180 from frosting. After the heat exchange of the evaporator 180, the air flow returns to the lower area of the first air duct 142 again, so as to form a circulating air flow.

Similarly, the air below the second air duct 144 can be returned to the cooling compartment 190 from the opening of the return air duct 150a to exchange heat with the evaporator 180, thereby defrosting the air.

In the present embodiment, since the inside of the first vertical partition 150 has the return air passage 150a communicating with the cooling compartment 190. When the damper 30 is in the fifth position, the airflow in the first air duct 142 and the airflow in the second air duct 144 can return to the cooling chamber 190 from the return air duct, exchange heat with the evaporator 180, and achieve defrosting.

In some embodiments, the damper 30 may be driven by a stepper motor. Specifically, the stepping motor may be configured with five rotational angles in advance before shipping to correspond to the first position, the second position, the third position, the fourth position, and the fifth position. And the stepper motor may also be controlled by a user or automatically by the system. For example, the damper 30 may be driven to a first position using a stepper motor when the user is only using the first compartment 101, the damper 30 may be driven to a third position using a stepper motor when the system detects that the temperature of the first and

second compartments

101, 102 has reached a target temperature value set by the user, etc.

In some embodiments, the opposing end faces of the first and second

vertical dividers

150 and 152 are each radiused. The two ends of the main section 310 are both adapted to the arc surface, and the end of the extension section 320 is adapted to the arc surface. Therefore, the air door 30 can be conveniently rotated, and the air door can be more tightly connected and is not easy to leak air.

In some embodiments, the refrigerator 1 further includes a first fan 410 disposed at the first air duct 142 and a second fan 420 disposed at the second air duct 144.

The first fan 410 and the second fan 420 may be used in conjunction with the damper 30. For example, when the first air duct 142 is turned on by the damper 30, the first fan 410 is correspondingly turned on to increase the airflow speed; when the second air duct 144 is opened by the damper 30, the second fan 420 is correspondingly turned on to increase the air flow speed.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
