DETAILED DESCRIPTION

[0036] In order to make the above objectives, features and advantages of the present application more clear and easily understood, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways from those described herein without departing from the scope of the present application and it is understood that similar improvements can be made by those skilled in the art without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0037] It should be noted that when a component is referred to as being "on" or "disposed on" another component, it can be directly on the other component or there can be intervening components. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or there can be intervening components. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms as used in the description of the present application are for the purpose of illustration only and do not indicate an exclusive embodiment.

[0038] In addition, the terms "first", "second", and the like, are used merely to describe the various components and do not imply or suggest relative importance or a quantity of the specified technical features. Thus, a feature defined with "first", "second" can include at least one of the feature explicitly or implicitly. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0039] In the present application, unless otherwise explicitly specified and limited, the "on", "under", "above", and "over" of a first feature to a second feature can be that the first feature is in direct contact with the second feature, or the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, the "above", "over", and "on" of a first feature to a second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the first feature is horizontally higher than the second feature. The "below", "under", and "underneath" of a first feature to a second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the first feature is horizontally lower than the second feature.

[0040] Unless otherwise defined, all technical and scientific terms used in the application's specification have the same meaning as commonly understood by one of ordinary skill in the art to which the application belongs. The terminology used in the application's specification is for describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0041] Referring to Figures 1 to 4 The application provides a refrigerator 100, which comprises a cabinet 10, a blowing mechanism 20, an ice making box 30 and a storage partition 40. The cabinet 10 is provided with a freezing chamber 11, a blowing passage 12 and a first air duct 13. The blowing passage 12 blows air to the freezing chamber 11 through the first air duct 13. The blowing mechanism 20 is installed on the cabinet 10 and can deliver cold air to the blowing passage 12. The ice making box 30 can be accommodated in the freezing chamber 11. The storage partition 40 is installed in the freezing chamber 11 and arranged close to the ice making box 30. The storage partition 40 is provided with a second air duct 41. One end of the second air duct 41 communicates with the blowing passage 12, and the other end communicates with the ice making box 30, so that the cold air in the blowing passage 12 can be delivered to the ice making box 30 through the second air duct 41. In this way, the second air duct 41 is arranged on the storage partition 40 and communicates with the blowing passage 12 and the ice making box 30. Thus, the cold air in the blowing passage 12 is directly delivered to the ice making box 30 through the second air duct 41. Therefore, when making ice, the cold air in the blowing passage 12 can quickly reach the ice making box 30, improving the ice making speed and efficiency. Meanwhile, the cold air supplied to the ice making box 30 for ice making no longer passes through the first air duct 13, and the circulating cold air is prevented from bringing odors into the ice making box 30, improving the quality of the ice. Moreover, the second air duct 41 is arranged on the storage partition 40 of the refrigerator, so that no additional air inlet pipeline is needed. Therefore, the structure is simple, and the cost is low.

[0042] As Figure 1 shown, the cabinet 10 is provided with a return air passage 14. The freezing chamber 11 is divided into a first chamber 111 and a second chamber 112 by the storage partition 40. The storage partition 40 is provided with a communication passage 42, which communicates the first chamber 111 and the second chamber 112 and does not communicate with the second air duct 41. The cold air passes through the first air duct 13, the first chamber 111, the communication passage 42, the second chamber 112 and the return air passage 14 in sequence and then returns to the blowing passage 12, so as to realize the circulation of the cold air in the first chamber 111 and the second chamber 112. Here, the communication passage 42 and the second air duct 41 are arranged to be not communicated with each other, which can prevent the circulating cold air in the freezing chamber 11 from entering the ice making box 30 and bringing odors in the freezing chamber 11 into the ice making box 30, thereby avoiding the ice made in the ice making box 30 from having odors and affecting the user experience.

[0043] As preferred, the number of the communication passages 42 is multiple, and the multiple communication passages 42 are arranged at intervals. In this way, the circulation of the cold air in the refrigerating chamber 11 can be ensured.

[0044] Here, the number of the communication passages 42 can be two, six, or eight, and the multiple communication passages 42 can be arranged on both sides or one side of the second air duct 41. The specific number and arrangement position of the communication passages 42 can be determined according to actual conditions and are not limited herein. In the embodiment, the number of the communication passages 42 is eight, and the eight communication passages 42 are arranged at intervals on both sides of the second air duct 41.

[0045] Further, the multiple communication passages 42 are arranged in two rows, and the two rows of communication passages 42 are arranged on both sides of the second air duct 41.

[0046] In an embodiment, as shown in Figure 1 , the air supply mechanism 20 includes an evaporator 21 and an air supply fan 22. The evaporator 21 is installed in the cabinet 10, and the air supply fan 22 is installed in the air supply passage 12. The air in the return air passage 14 continues to maintain the preset temperature after heat exchange with the evaporator 21, and then continues to be sent out through the air supply passage 12 under the action of the air supply fan 22.

[0047] Please continue to refer to Figure 1 , the refrigerator 100 further includes a switching mechanism 50 arranged at the communication position of the air supply passage 12 and the first air duct 13, or arranged at the communication position of the air supply passage 12 and the second air duct 41. The switching mechanism 50 selectively opens and closes the first air duct 13 or the second air duct 41. That is, the switching mechanism 50 either opens the first air duct 13 and closes the second air duct 41, or closes the first air duct 13 and opens the second air duct 41. Here, opening the first air duct 13 or opening the second air duct 41 corresponds to two working modes respectively. Regardless of which way, the purpose of the switching mechanism 50 is to make the maximum or most cold air enter the corresponding air duct.

[0048] Specifically, the switching mechanism 50 includes a driving member (not shown), a mounting seat 51, and a baffle 52. The mounting seat 51 is mounted on the inner wall of the second air duct 41, and the baffle 52 is connected with the driving member and movably mounted on the mounting seat 51 at one end and connected with the driving member, and at the other end, the baffle 52 can selectively close the first air duct 13 and open the second air duct 41, or close the second air duct 41 and open the first air duct 13.

[0049] Here, the driving member can be a motor or a pneumatic cylinder.

[0050] As preferred, when the first air duct 13 is opened and the second air duct 41 is closed, the angle between the baffle 52 and the flow direction of the cold air delivered at the inlet of the first air duct 13 is 0-15 degrees. In this way, the cold air can be ensured to flow into the first air duct 13 basically, and the baffle 52 will not be damaged by the impact pressure of the cold air, so as to complete the cold air circulation and ensure the original refrigeration function of the freezing chamber 11.

[0051] Here, the angle between the baffle 52 and the flow direction of the cold air delivered at the inlet of the first air duct 13 can be 0°, 3°, 7°, 12°, 15°, and the specific angle can be set according to the actual situation, which is not limited here. In the embodiment, the angle between the baffle 52 and the flow direction of the cold air delivered at the inlet of the first air duct 13 is 5°.

[0052] In an embodiment, as shown in Figure 5 The refrigerator 100 further comprises an ice-making signal output member 60, which is in signal connection with the switching mechanism 50; wherein the ice-making signal output member 60 can generate an ice-making signal 61 and transmit it to the switching mechanism 50, and the switching mechanism 50 can open the second air duct 41 and close the first air duct 13 according to the ice-making signal 61, so that the cold air in the air supply channel 12 enters the ice-making box 30 through the second air duct 41. In this way, the user can directly output an ice-making instruction through the ice-making signal output member 60 to control the switching mechanism 50 to switch the refrigerator 100 to the ice-making mode, which is more convenient and intelligent than the manual switching mode, and improves the user experience.

[0053] Here, the ice-making signal output member 60 can be a sensor, a switch, etc. The ice-making signal output member 60 and the driving member can be in signal transmission through a wire or through wireless signal transmission.

[0054] In an embodiment, as shown in Figure 1 or Figure 3 The refrigerator 100 further comprises a cabinet door 70, which is rotatably connected to the cabinet 10 and used to open and close the freezing chamber 11; and the ice-making box 30 is installed on the cabinet door 70. It can be understood that the ice-making box 30 is installed on the cabinet door 70, which is convenient for the user to put water required for ice-making into the ice-making box 30, and further improves the user experience.

[0055] It should be noted that the freezing chamber 11 can transmit the ice-making signal 61 to the switching mechanism 50 through the ice-making signal output member 60, so that it is in the ice-making state, that is, the first air duct 13 is closed and the second air duct 41 is opened at this time; when the user has no ice-making demand, the freezing chamber 11 is in the cold air circulation state, that is, the first air duct 13 is opened and the second air duct 41 is closed at this time.

[0056] The following describes the cold air passing path of the freezing chamber 11 in different states:

[0057] like Figure 3 As shown, in the cold air circulation state, the cold air passes through the first air duct 13, the first chamber 111, the connecting channel 42, the second chamber 112 and the return air channel 14 in sequence from the air supply channel 12, and then returns to the air supply channel 12, completing the circulation and keeping the freezer 11 at a low temperature.

[0058] like Figure 4 As shown, during ice-making, the baffle 52 closes the first air duct 13, and cold air is directly delivered from the air supply duct 12 to the second air duct 41, and then enters the ice-making box 30 through the second air duct 41 to continuously deliver cold air into the ice-making box 30 so that it can make ice quickly.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
