[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0032] See also Figure 1 As shown, Figure 1 The first structural diagram of the refrigerator provided in the embodiment of the present application. The embodiment of the present application provides a refrigerator 100, which can be a dual-system refrigerator, where the refrigerating compartment and the freezing compartment respectively have independent air supply and return systems and corresponding evaporators, that is, the two only share the compressor and condenser parts, which can save the setting of devices and effectively prevent the food in the refrigerating compartment and the freezing compartment from odor contamination.

[0033] Please combine Figure 1 Also see Figure 2 As shown, Figure 2A second structural schematic diagram of a refrigerator provided in an embodiment of the present application. Exemplarily, the refrigerator 100 includes a refrigerating compartment 110 and a variable temperature chamber 120. Of course, the refrigerator 100 may also include a freezing compartment (not shown in the figure). For a cross four-door refrigerator, the top of the refrigerator is a refrigerating compartment 110 with double doors, and the drawer space of the refrigerating compartment 110 may be provided with a variable temperature chamber 120. It is understandable that the volume of the refrigerating compartment 110 is greater than the volume of the variable temperature chamber 120. The operating temperature range of the refrigerating compartment 110 is 2°C to 8°C, which can realize low-temperature storage of food materials, and the storage time can be within one week. The variable temperature chamber 120 is a storage space in the refrigerator 100 that can adjust the temperature, and can be used for multiple functions such as refrigerated storage and frozen storage. For example, the operating temperature range of the variable temperature chamber 120 is -3°C to 4°C. The refrigerating compartment 110 and the variable temperature chamber 120 share a set of air supply systems. However, since the refrigerating compartment and the variable temperature chamber need to be configured with air doors respectively, the cost of the refrigerator increases.

[0034] In order to reduce the occurrence of the above situation, the embodiment of the present application improves the air supply assembly shared by the refrigeration compartment 110 and the temperature-changing chamber 120, which will be described below.

[0035] Please combine Figure 1 and Figure 2 Also see Figure 3 As shown, Figure 3 The schematic diagram of the structure of the air supply assembly of the refrigerator provided in the embodiment of the present application is shown at one angle. Exemplarily, the refrigerator 100 further includes an air supply assembly 130, which is used to supply air to the refrigerating compartment 110 and the temperature-changing chamber 120 respectively.

[0036] For example, the air supply assembly 130 includes a fan 131 , a refrigeration air duct 132 , a temperature variable air duct 133 , a baffle 134 and a temperature variable air door 135 .

[0037] The fan 131 is used to accelerate the flow of air, such as blowing the cold air generated by the compressor, the condenser and the evaporator to the room that needs to be refrigerated. The fan 131 has a first air outlet 1310. For example, a fan cover can be provided to cover the fan 131, and the first air outlet 1310 is provided as the outlet for the fan 131 to blow air.

[0038] The refrigeration air duct 132 is used to guide the air blown by the fan 131 into the refrigeration compartment 110, so as to achieve refrigeration of the refrigeration compartment 110. One end of the refrigeration air duct 132 is covered with a first air outlet 1310, and the other end of the refrigeration air duct 132 is connected to the refrigeration compartment 110 to supply air to the refrigeration compartment 110.

[0039] The variable temperature air duct 133 is used to guide the air blown by the fan 131 into the variable temperature chamber 120, so as to realize cooling of the variable temperature chamber 120. One end of the variable temperature air duct 133 is covered with a first air outlet 1310, that is, the variable temperature air duct 133 can share one end with the refrigeration air duct 132 to realize communication with the first air outlet 1310. The other end of the variable temperature air duct 133 is communicated with the variable temperature chamber 120 to supply air to the variable temperature chamber 120.

[0040] The baffle 134 is disposed in the first air outlet 1310 and divides the first air outlet 1310 into a variable temperature air outlet 1312 and a refrigeration air outlet 1314 so as to guide air to be supplied to the variable temperature chamber 120 and the refrigeration chamber 110 respectively.

[0041] The temperature variable air door 135 is rotatably connected to the temperature variable air duct 133 to guide or block the wind from entering the temperature variable room 120. That is, the temperature variable air door 135 can close the temperature variable air duct 133 to prevent the wind from entering the temperature variable room 120 through the temperature variable air duct 133; the temperature variable air door 135 can also expose the temperature variable air duct 133, that is, in an unblocked state, so that the wind can be guided to enter the temperature variable room 120 through the temperature variable air duct 133. The rotation of the temperature variable air door 135 can be driven by a motor, and the opening and closing timing of the temperature variable air door 135 can be controlled by a control system.

[0042] In the air supply assembly 130 provided in the embodiment of the present application, the air supply control of the variable temperature chamber 120 is achieved through the variable temperature air door 135, so that the refrigeration demand of the variable temperature chamber 120 can be met, and the refrigeration demand of the refrigeration compartment 110 can be achieved simultaneously, the setting of the refrigeration air door is eliminated, and the production cost of the refrigerator 100 is reduced.

[0043] It should be noted that the embodiment of the present application eliminates the refrigeration damper, and has certain requirements for the refrigeration sequence of the refrigeration compartment 110 and the temperature-changing compartment 120, so as to reduce the waste of cooling capacity, or reduce the impact on the temperature of the refrigeration compartment 110. The design of the air supply assembly 130 in the embodiment of the present application can make the temperature-changing compartment 120 have a larger air volume, so that the temperature-changing compartment 120 reaches the working temperature before the refrigeration compartment 110, and then the temperature-changing damper 135 can be closed to realize the refrigeration of the refrigeration compartment 110 until the refrigeration compartment 110 reaches the working temperature.

[0044] Exemplarily, the outlet area of ​​the variable temperature air outlet 1312 is larger than the outlet area of ​​the refrigerated air outlet 1314. When air is supplied to the variable temperature chamber 120 and the refrigerated compartment 110 at the same time, more wind can be guided into the variable temperature chamber 120, that is, the variable temperature chamber 120 can obtain a larger air distribution volume.

[0045] Furthermore, the baffle 134 is spaced from the fan 131 so that the variable temperature air outlet 1312 is connected to the refrigerated air outlet 1314. In this way, when air is supplied to the variable temperature chamber 120 and the refrigerated compartment 110 at the same time, the air supplied to the variable temperature chamber 120 can enter through the variable temperature air outlet 1312 or be supplied to the variable temperature chamber 120 from the refrigerated air outlet 1314 via the variable temperature air outlet 1312, thereby further increasing the air distribution volume of the variable temperature chamber 120.

[0046] Exemplarily, the variable temperature air duct 133 and the baffle 134 are arranged to form a second air outlet 1330, and the variable temperature air door 135 serves as both the air door of the variable temperature air duct 133 and the air door of the second air outlet 1330. The variable temperature air door 135 can abut against the baffle 134 to close the second air outlet 1330, and the variable temperature air door 135 can also be separated from the baffle 134 to expose the second air outlet 1330.

[0047] Exemplarily, the variable temperature chamber 120 and the refrigerating chamber 110 are refrigerated synchronously, at which time the variable temperature air door 135 abuts against the baffle 134, and the air blown by the fan 131 is respectively sent to the variable temperature chamber 120 through the variable temperature air outlet 1312 and sent to the refrigerating chamber 110 through the refrigerating air outlet 1314. Since the volume of the variable temperature chamber 120 is smaller than the volume of the refrigerating chamber 110, and the air outlet area of ​​the variable temperature air outlet 1312 is larger than the air outlet area of ​​the refrigerating air outlet 1314, the variable temperature chamber 120 reaches the operating temperature before the refrigerating chamber 110. After the variable temperature room 120 reaches the working temperature, the variable temperature air door 135 closes the variable temperature air duct 133, thereby exposing the second air outlet 1330. At this time, the air sent by the fan 131 is sent to the refrigerated compartment 110 through the refrigerated air outlet 1314 and the second air outlet 1330 through the refrigerated air duct 132, until the refrigerated compartment 110 reaches the working temperature, and then the refrigeration device can be turned off. It should be noted that since the working temperature of the refrigerated compartment 110 is different from the working temperature of the variable temperature room 120, when the working temperature of the variable temperature room 120 is lower than the temperature of the refrigerated compartment 110, if the variable temperature room 120 and the refrigerated compartment 110 are refrigerated simultaneously and continuously, since there is no refrigerated air door, when the variable temperature room 120 reaches the working temperature, the temperature of the refrigerated compartment 110 will continue to decrease, affecting the accuracy of the refrigeration of the refrigerated compartment 110.

[0048] Please combine Figures 1 to 3 Also see Figure 4 As shown, Figure 4 A schematic structural diagram of the air supply assembly of the refrigerator provided in an embodiment of the present application from another angle. Exemplarily, the baffle 134 includes a bent partition 1340 and a limiter 1342, and the limiter 1342 is used to limit the variable temperature air door 135 to prevent the variable temperature air door 135 from rotating excessively and causing the second air outlet 1330 to be unable to be closed.

[0049] Since the volume of the refrigerating compartment 110 is relatively large, in order to make the air evenly enter the refrigerating compartment 110, a plurality of air supply ports can be provided for the refrigerating air duct 132. The refrigerating air duct 132 has at least two air supply ports 1320, each of which is in communication with the refrigerating compartment 110 to evenly supply air to the refrigerating compartment 110. For example, the refrigerating air duct 132 has four air supply ports 1320, and every two air supply ports 1320 are arranged opposite to each other along the width direction of the refrigerator 100, so that air can be supplied to the refrigerating compartment 110 from different positions, which not only speeds up the refrigerating speed of the refrigerating compartment 110, but also makes the coldness of the refrigerating compartment 110 evenly distributed.

[0050] It should be noted that the space inside the refrigerator 100 can be saved by reasonably arranging the positional relationship between the refrigeration air duct 132 and the variable temperature air duct 133 and the fan 131. Exemplarily, the air supply assembly 130 has a first direction X and a second direction Y that are perpendicular to each other. The first direction X can be understood as the height direction of the refrigerator 100, and the second direction Y can be understood as the width direction of the refrigerator 100. Among them, the refrigeration air duct 132 is arranged on one side of the fan 131 along the first direction X, for example, it can be arranged above the fan 131; the variable temperature air duct 133 is arranged on one side of the fan 131 along the second direction Y, for example, it is arranged on the left side of the fan 131. In addition, the variable temperature air duct 133 and the refrigeration air duct 132 are integrally formed, which can reduce the problem of air leakage caused by unstable connection.

[0051] In the air supply assembly 130 and the refrigerator 100 provided in the embodiment of the present application, the air supply control of the variable temperature chamber 120 is realized by the variable temperature air door 135, so that the refrigeration demand of the variable temperature chamber 120 can be met, and the refrigeration demand of the refrigerating compartment 110 can be realized synchronously, and the setting of the refrigerating air door is eliminated, thereby reducing the manufacturing cost of the refrigerator 100. In addition, the variable temperature chamber 120 and the refrigerating compartment 110 are refrigerated synchronously, and the variable temperature chamber 120 reaches the working temperature before the refrigerating compartment 110, which can fully utilize the cooling capacity and avoid interfering with the working temperature of the refrigerating compartment 110.
