The evaporator is configured to directly or indirectly provide cold to the storage compartment. Since the refrigeration system of the refrigeration and freezing device itself is well known to those skilled in the art, it will not be described in detail here. A cooling chamber may be provided in the cabinet 20, specifically, it may be provided at the rear side of the storage compartment. When a freezer compartment is provided in the cabinet 20, the cooling chamber is preferably provided at the rear side of the freezer compartment. The cooling chamber is used to accommodate the evaporator.

[0036] In some embodiments of the present invention, Figure 1 As shown, the storage compartment can be divided into a plurality of storage spaces 21.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, a plurality of air supply ports 31 are arranged on a space wall of each storage space 21, and the plurality of air supply ports 31 are arranged at intervals along a circumferential direction. For example, a stationary turntable 30 is arranged on a space wall of each storage space 21, and a plurality of air supply ports 31 are arranged on the stationary turntable 30. A return air port 32 is arranged at the bottom of each storage space 21. The refrigeration and freezing device further includes an air duct device, which has an air supply duct 33 connecting the cooling chamber and each air supply port 31, and a return air duct connecting each return air port 32 and the cooling chamber.

[0038] In particular, the refrigerating and freezing device further comprises a plurality of shielding turntables 50.

That is, the shielding turntable 50 blocks different numbers of air outlets 31 by rotating, so that the air intake volume in the corresponding storage space 21 can be adjusted.

[0039] In the embodiment of the present invention, each storage space 21 has a shielding turntable 50 that can control the air intake, that is, the air intake is adjustable to adjust and control the temperature of the temperature zone of the corresponding storage space 21, and each storage space 21 has a return air vent 32, which can realize independent partitioning of the refrigerator refrigeration compartment, and can make the refrigeration compartment have multiple storage temperature storage partitions, so that users can place different foods in the corresponding optimal storage environment area according to their needs, and guide users to correctly place the best storage space for food. That is, the refrigeration and freezing device of the present invention can realize precise temperature control of partitions, and realizes independent and adjustable temperature control of different refrigeration temperature zones by means of accurate and independent air supply and independent return of air through the shielding turntable 50. Each partition is provided with a separate return air vent 32 to avoid interference between different temperature zones, that is, to reduce disturbances and accurately control temperature control.

[0040] In some embodiments of the present invention, Figures 2 to 6As shown, there are four air supply ports 31 arranged on a space wall of each storage space 21, and they are evenly distributed in the circumferential direction, and they are respectively the first air supply port 34, the second air supply port 35, the third air supply port 36 and the fourth air supply port 37 in the clockwise direction. The connecting holes 51 on each shielding turntable 50 include: a first connecting hole 61, a second connecting hole 62, a third connecting hole 63 and a fourth connecting hole 64 evenly distributed in the circumferential direction and arranged in the clockwise direction, a fifth connecting hole 65 and a sixth connecting hole 36 evenly distributed between the first connecting hole 61 and the second connecting hole 62, a seventh connecting hole 67 and an eighth connecting hole 68 evenly distributed between the second connecting hole 62 and the third connecting hole 63, and a ninth connecting hole 69 arranged between the third connecting hole 63 and the fourth connecting hole 64; and the line between the hole centers of the ninth connecting hole 69 and the third connecting hole 63 passes through the center of the shielding turntable 50.

[0041] like Figure 4 As shown, the four air supply ports 31 can be connected to the corresponding storage space 21, that is, the first air supply port 34, the second air supply port 35, the third air supply port 36 and the fourth air supply port 37 are aligned with the first connecting hole 61, the second connecting hole 62, the third connecting hole 63 and the fourth connecting hole 64 respectively. Figure 5 As shown, the three air outlets 31 can be connected to the corresponding storage space 21, that is, the shielding turntable 50 shields the first air outlet 34, the fifth connecting hole 65 is aligned with the second air outlet 35, the seventh connecting hole 67 is aligned with the third air outlet 36, and the ninth connecting hole 69 is aligned with the fourth air outlet 37. Figure 6 As shown, the two air outlets 31 can be connected to the corresponding storage space 21, that is, the shielding turntable 50 shields the first air outlet 34 and the fourth air outlet 37, the sixth connecting hole 36 is aligned with the second air outlet 35, and the eighth connecting hole 68 is aligned with the third air outlet 36.

[0042] In some alternative embodiments of the present invention, the number of air outlets 31 on the stationary rotating disk 30 may be other values, and the number of connecting holes 51 on the shielding rotating disk 50 may be other values. In other words, in theory, the two rotating disks can achieve countless matching states.

[0043] In some embodiments of the present invention, a plurality of storage spaces 21 are arranged in two rows, and the storage spaces 21 in each row are arranged in sequence along the up-down direction. A space wall of each storage space 21 is the rear wall of the storage space 21; the air supply duct 33 is arranged at the rear center of the storage compartment. Each return air port 32 can be arranged at one end of the lower part of the rear wall of the corresponding storage space 21. A drawer is arranged in at least one storage space 21, for example, drawers can be arranged in the two storage spaces 21 at the bottom.

[0044] In some embodiments of the present invention, a sealing device is provided between each horizontal partition 41 and the box body 20 for sealing connection. A corresponding structure may also be provided on the rear side of the door body to separate the multiple storage spaces 21 as much as possible. For example, the refrigeration and freezing device may also include at least one bottle holder and at least one vertical partition structure. At least one bottle holder is provided on the rear side of the door body, and each bottle holder is located in front of a horizontal partition 41, and when the door body is closed, each bottle holder is in contact with the horizontal partition 41. At least one vertical partition structure is provided on the rear side of the door body. Each vertical partition structure may be a partition plate that is vertically arranged, and is located in front of a vertical partition 42, and when the door body is closed, each vertical partition structure is in contact with the vertical partition 42.

[0045] In some embodiments of the present invention, the refrigeration and freezing device may further include a gear generation device. The gear generation device is configured to generate a plurality of gear instruction groups; each gear instruction group includes a plurality of gear instructions, and each gear instruction group corresponds to controlling a storage space 21; each gear instruction includes control information for making the corresponding storage space 21 at a target temperature or within a target temperature range, so that the refrigeration and freezing device controls the shielding turntable 50 according to each gear instruction, thereby controlling the temperature in the corresponding storage space 21.

[0046] For example, in some embodiments, the gear generation device includes a plurality of display panels, which are arranged on the inner side wall of each storage space 21, and each display panel is configured to receive a signal and generate a gear instruction of a gear instruction group; and each display panel is also configured to display the type of items recommended to be stored in the corresponding storage space 21. Each display panel can be arranged adjacent to the corresponding storage space 21. Furthermore, each display panel can input information by sliding, clicking, etc. In some alternative embodiments of the present invention, the gear generation device can be a total touch display screen of a refrigeration and freezing device.

[0047] In other embodiments, the gear generation device includes a plurality of adjustment buttons, and an indication icon corresponding to each gear instruction of each adjustment button. Each indication icon includes at least information suggesting the type of items stored in the corresponding storage space 21. Each adjustment button may be a mechanical key structure such as a knob. The indication icon may be an icon arranged on the inner side of the refrigerator body 20 near the adjustment button, and may be arranged in a manner such as engraving, silk screen printing, or hollow structure. For example, the indication icon may be a symbol representing an item suggesting the type of items stored in the corresponding storage space 21. Further, each indication icon includes at least a target temperature or a target temperature range in the corresponding storage space 21. The gear generation device may also include a plurality of indicator lights. Each gear instruction of each adjustment button is associated with an indicator light, so that when the adjustment button indicates the corresponding gear instruction, the corresponding indicator light is turned on, thereby highlighting the corresponding indication icon, i.e., lighting it up, for the convenience of user observation. Alternatively, the indication icon may also be displayed on a display screen, so that the mechanical button and the display screen display can be combined. Furthermore, the indicator icon may also be directly text, that is, the display screen may display all information associated with the corresponding gear position instruction.

[0048] In this embodiment, because of the shielding turntable 50 and the gear generating device, the refrigerator refrigeration compartment can be independently partitioned, and each partition can achieve multiple temperature levels such as 2°C, 5°C, 10°C (low, medium, high) and independent adjustment, so that the user can adjust the temperature of each storage space 21 of the refrigerator according to their needs and habits, and achieve the best storage environment area for different foods through balanced control of temperature and humidity, and guide the user to correctly place the food in the best storage space. Before this application, the temperature of the refrigerator refrigeration space was the same, but the best storage temperature and humidity of different foods were different, resulting in users not daring to put some ready-to-eat tropical fruits and melons with low storage temperature into the refrigerator. The temperature is too low to be eaten immediately, and the user can only put them outside; and tropical fruits need to be stored in the range of 8-10°C for the best storage time, and dare not put them in the refrigerator. The food put into the refrigerator is not in the best temperature range, the food decays quickly, and the waste is serious. The embodiment of the present invention can freely adjust the temperature of each storage space of the refrigerator refrigeration according to the needs of the user, so that the food is stored in the best storage space, and guide the user to correctly place the best storage space for food. Each storage space 21 has its own independent air outlet and independent air return, and each storage space 21 can achieve multiple temperature changes and switch freely.

[0049] Furthermore, when the number of gear instructions in each gear instruction group is relatively large, for example, each change of one degree Celsius in the target temperature in the storage space 21 can be used as a new gear. This can also be called stepless gear adjustment. For example, there can be 11 gears between 0°C and 10°C, so that each storage space 21 can adjust the temperature arbitrarily between 0°C and 10°C. Of course, only three gears can be set between 0°C and 10°C: 0°C ice temperature zone, 4°C gold zone, and 10°C tropical fruit zone.

[0050] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
