[0069] As described in the background technology, in order to prevent the temperature of the ice-making room from being affected by the temperature of other compartments, the ice-making room and the freezer compartment use different evaporators. The first evaporator provides cold air to the freezer compartment through the first air duct assembly, and the second evaporator provides cold air to the ice-making room through the second air duct assembly. The advantage of the independent ice-making system is that it is not affected by the refrigeration of other compartments and can be independently refrigerated and defrosted. If the evaporator is shared with the freezer compartment, it will be significantly affected by the freezing door opening and defrosting. When the freezer compartment is put into heat load or the door is opened for a long time, the temperature of the first evaporator is high, resulting in insufficient cold air delivered to the ice-making room, which can easily cause problems such as ice melting or slow ice making in the ice-making room.

[0070] However, the first air duct assembly and the second air duct assembly are located in the box, and the first air duct assembly and the second air duct assembly occupy a large space, and the effective volume of the refrigerator is small.

[0071] Therefore, in order to solve the above-mentioned technical problems, in the air-cooled refrigerator of the present application, the second air duct assembly is located outside the box, which is beneficial to increase the effective volume of the refrigerator.

[0079] See also Figures 1 to 3 As shown, this embodiment provides an air-cooled refrigerator, including a box body 100.

[0080] The housing 100 may be configured with a first chamber 110 and a second chamber 120 .

[0081] In some embodiments, the first chamber 110 is located above the second chamber 120. Alternatively, the first chamber 110 may be located below the second chamber 120, or the first chamber 110 and the second chamber 120 may be arranged side by side along the width direction of the box 100. The width direction is the direction shown by the X axis in the figure.

[0082] In some embodiments, the box 100 includes an outer shell 130. The outer shell 130 can play a protective role.

[0083] In some embodiments, the outer shell 130 is configured with a first receiving cavity having a first access opening and a second access opening, and the first access opening and the second access opening are respectively arranged on opposite sides of the outer shell 130 in the depth direction of the box body 100. The first access opening can be arranged on the front side of the outer shell 130, and the second access opening can be arranged on the rear side of the outer shell 130.

[0086] In some embodiments, the box body 100 includes a box liner. The box liner can be used to form a cold source chamber and a refrigeration chamber. It is understood that the refrigeration chamber can include at least one of a freezing chamber, a temperature-changing chamber, and a refrigeration chamber.

[0087] In some embodiments, the number of the casing may be one, and the casing may be configured with a first chamber 110 and a second chamber 120 .

[0088] The box is located inside the outer shell 130 and is provided with at least one refrigeration compartment. The box has a third access opening, which is opposite to the first access opening. Items can be placed in the refrigeration compartment through the third access opening and the first access opening.

[0089] In some embodiments, the tank may include a first tank 140 and a second tank 150 . The first tank 140 is configured with a first chamber 110 , and the second tank 150 is configured with a second chamber 120 .

[0090] In some embodiments, a foam layer is filled between the box liner, the outer shell 130 and the press chamber 160, and the foam layer is used to insulate the refrigeration compartment, thereby ensuring the refrigeration effect in the refrigeration compartment.

[0091] In some embodiments, the refrigerator includes a door body (not shown in the figures).

[0092] The door body can be opened and closed on the front side of the box body 100 to close and open the refrigeration compartment and take and put items in the refrigeration compartment. It should be noted that the number of the door bodies can be one, two or more.

[0093] In some embodiments, the refrigerator includes an ice maker 200 for making ice cubes. The ice maker 200 is configured with an ice making chamber.

[0094] In some embodiments, ice maker 200 is located within first chamber 110 .

[0095] In some embodiments, the remaining area of ​​the first chamber 110 may be a refrigerating chamber.

[0096] See also Figures 4 to 9 As shown, in some embodiments, the refrigerator includes a first air duct assembly 300. The first air duct assembly 300 is used to guide the flow of air.

[0097] The first air duct assembly 300 is located in the second chamber 120 to separate the second chamber 120 into a cold source chamber 121 and a freezing chamber 122. The cold source chamber 121 can be used to place an evaporator, and the freezing chamber 122 can be used to freeze items.

[0098] It can be understood that the second chamber 120 is divided into a cold source chamber 121 and a freezing chamber 122 by the first air duct assembly 300, and the cold source chamber 121 is used to install the first evaporator 400 and the second evaporator 500, so that the two evaporators can be shielded by using one first air duct assembly 300, which is beneficial to reduce the number of materials, improve assembly efficiency and reduce costs.

[0099] See also Fig. 9 and Fig.10 As shown, in some embodiments, the cold source chamber 121 includes a first installation cavity 1211 and a second installation cavity 1212 .

[0100] In some embodiments, the refrigerator includes a divider 600 .

[0101] The partition 600 is located in the cold source chamber 121 , and the partition 600 cooperates with the first air duct assembly 300 to divide the cold source chamber 121 into a first installation chamber 1211 and a second installation chamber 1212 .

[0102] In some embodiments, the partition 600 may be integrally provided with the second box 150. For example, the second box 150 and the partition 600 are obtained by vacuum forming, and the partition 600 and the box are integrally formed, and the partition 600 does not need to be separately installed later.

[0103] In other embodiments, the partition 600 may be detachably connected to the second box 150. For example, the partition 600 may be a separate piece, and after the second box 150 is foamed, the partition 600 is fixed in the second box 150 by buckles or screws.

[0104] In some embodiments, the partition 600 may be a plastic member.

[0105] In some embodiments, the first installation cavity 1211 and the second installation cavity 1212 are arranged side by side along the width direction of the box body 100, and the second installation cavity 1212 is close to the ice maker 200. In this way, the refrigerated air in the second installation cavity 1212 is conveniently transported to the ice making room of the ice maker 200.

[0106] See also Figure 3 As shown, in some embodiments of the present application, a third air duct assembly 700 is further included, and the first installation cavity 1211 is connected to the first chamber 110 through the third air duct assembly 700. In this way, the first evaporator 400 can provide cold energy for the freezing chamber 122 and also provide cold energy for the first chamber 110.

[0107] See also Figures 7 to 9 As shown, in some embodiments, the refrigerator includes a first evaporator 400 .

[0108] The first evaporator 400 is located in the first installation cavity 1211, and the first installation cavity 1211 is connected to the freezing chamber 122 through the first air duct assembly 300;

[0109] See also Figure 7 As shown by the middle arrow, during operation, the first evaporator 400 cools the air in the first installation cavity 1211 , and the cooled air enters the freezing chamber 122 through the first air duct assembly 300 .

[0110] See also Fig. 9 As shown, in some embodiments, the refrigerator includes a second evaporator 500 .

[0111] The second evaporator 500 is located in the second installation cavity 1212 , and the second installation cavity 1212 is connected to the ice-making chamber through the second air duct assembly 800 .

[0112] During operation, the second evaporator 500 cools the air in the second installation cavity 1212 , and the cooled air enters the ice-making chamber through the second air duct assembly 800 .

[0113] It is understandable that the ice-making chamber and the freezing chamber 122 use different evaporators for refrigeration and are unlikely to affect each other.

[0114] See also Figure 3As shown, in some embodiments, the second air duct assembly 800 is located outside the cabinet, so that the second air duct assembly 800 does not need to occupy the space inside the cabinet, which is beneficial to increase the volume of the refrigerator.

[0115] See also Figure 4 and Fig. 9 As shown, in some embodiments, the refrigerator includes a damper assembly 900 .

[0116] The damper assembly 900 is disposed on the partition 600 , and the damper assembly 900 is configured to make the first installation cavity 1211 and the second installation cavity 1212 communicate with each other or not communicate with each other.

[0117] When the ice making chamber needs to be cooled quickly, the damper assembly 900 is opened, and the first installation cavity 1211 is connected to the second installation cavity 1212. The first evaporator 400 cools the air in the first installation cavity 1211, and the second evaporator 500 cools the air in the second installation cavity 1212. The air cooled by the first installation cavity 1211 enters the second installation cavity 1212 through the damper assembly 900, and then enters the ice making chamber together with the air cooled by the second installation cavity 1212 through the second air duct assembly 800.

[0118] Alternatively, when the cooling capacity of the first evaporator 400 is surplus, the damper assembly 900 is opened, and the first installation cavity 1211 is connected to the second installation cavity 1212. The first evaporator 400 cools the air in the first installation cavity 1211, and the second evaporator 500 cools the air in the second installation cavity 1212. The air cooled by the first installation cavity 1211 enters the second installation cavity 1212 through the damper assembly 900, and then enters the ice making chamber through the second air duct assembly 800 together with the air cooled by the second installation cavity 1212.

[0119] When the freezing chamber 122 needs to be cooled quickly, the damper assembly 900 is opened, and the first installation cavity 1211 is connected to the second installation cavity 1212. The first evaporator 400 cools the air in the first installation cavity 1211, and the second evaporator 500 cools the air in the second installation cavity 1212. The cooled air in the second installation cavity 1212 enters the first installation cavity 1211 through the damper assembly 900, and then enters the freezing chamber 122 through the first air duct assembly 300 together with the cooled air in the first installation cavity 1211.

[0120] Alternatively, when the cooling capacity of the second evaporator 500 is surplus, the damper assembly 900 is opened, and the first installation cavity 1211 is connected to the second installation cavity 1212. The first evaporator 400 cools the air in the first installation cavity 1211, and the second evaporator 500 cools the air in the second installation cavity 1212. The air cooled in the second installation cavity 1212 enters the first installation cavity 1211 through the damper assembly 900, and then enters the freezing chamber 122 through the first air duct assembly 300 together with the air cooled in the first installation cavity 1211.

[0121] When rapid cooling is not required, the damper assembly 900 is closed, and the first installation cavity 1211 and the second installation cavity 1212 are not connected.

[0122] It is understandable that the refrigerator provided by the present application divides the cold source chamber 121 into a first installation chamber 1211 and a second installation chamber 1212 by setting a partition 600, the first evaporator 400 is located in the first installation chamber 1211, the first installation chamber 1211 is connected to the freezing chamber 122 through the first air duct assembly 300, the second evaporator 500 is located in the second installation chamber 1212, the second installation chamber 1212 is connected to the ice making chamber through the second air duct assembly 800, and the damper assembly 900 is provided on the partition 600, and the damper assembly 900 is used to make the first installation chamber 1211 and the second installation chamber 1212 connected or disconnected. When a single chamber needs to be cooled quickly, the damper assembly 900 is opened to transfer the cold of the two evaporators to the single chamber, thereby improving the rapid cooling capacity.

[0123] See also Fig.10 and Fig.11 As shown, in some embodiments of the present application, the partition 600 is configured with an opening 610, and the opening 610 is communicated with the first installation cavity 1211 and the second installation cavity 1212. The damper assembly 900 is disposed in the opening 610. In this way, the damper assembly 900 occupies less space.

[0124] In other embodiments, the damper assembly 900 is disposed on one side of the partition 600 , and the damper assembly 900 moves relative to the partition 600 to cover the opening 610 on the partition 600 , or to open the opening 610 on the partition 600 .

[0125] In some embodiments of the present application, in order to achieve automatic control, the damper assembly 900 may be an electric damper.

[0126] See also Figure 3 , Fig.12 and Fig.13As shown, in some embodiments of the present application, the housing 100 is constructed with a return air port 151 and an air supply port 152 , and both the return air port 151 and the air supply port 152 are connected to the second installation cavity 1212 and are connected to the second air duct assembly 800 .

[0127] During operation, the air in the second installation cavity 1212 flows to the second installation cavity 1212 through the air supply port 152, the second air duct assembly 800, the ice making chamber, the second air duct assembly 800 and the return air port 151 in sequence. Among them, the opening 610 is close to the air supply port 152. That is, compared with the return air port 151, the distance between the air supply port 152 and the opening 610 is closer. In this way, it can effectively prevent the hotter air from the ice making chamber flowing back into the second installation cavity 1212 from entering the first installation cavity 1211 through the opening 610 on the partition 600.

[0128] See also Fig. 9 As shown, in some embodiments, the air supply port 152 is located above the second evaporator 500 , and the air return port 151 is located below the second evaporator 500 .

[0129] Specifically, the second box 150 is provided with a return air port 151 and an air supply port 152, both of which are connected to the second installation cavity 1212. The first box 140 is provided with an ice making air inlet and an ice making air outlet, both of which are connected to the ice making chamber.

[0130] In some embodiments of the present application, the air supply port 152 is located on the side of the return air port 151 facing the first chamber 110. In this way, the air supply port 152 is close to the ice making chamber, which facilitates the delivery of cold air in the second installation chamber 1212 to the ice making chamber.

[0131] See also Fig.12 and Fig.13 As shown, in some embodiments, the box liner is configured with a first drain port 153, which is communicated with the first installation cavity 1211. The box liner is configured with a second drain port 154, which is communicated with the second installation cavity 1212. In this way, the requirements of independent defrosting and drainage of the first evaporator 400 and the second evaporator 500 can be met.

[0132] Specifically, the first tank 140 may be located on the top of the second tank 150 , and the bottom of the second tank 150 is configured with a first drain port 153 and a second drain port 154 .
