The box 1 in this embodiment is cylindrical, and the shelf 2 is vertically arranged.

As an alternative embodiment, referring to fig. 4, more than two air channels which are respectively communicated with each area individually and provided with a refrigerating module are defined on the box 1, and second partition plates 112 for separating the air channels are arranged on the top and/or the bottom of the box 1, and each second partition plate 112 is in contact and sealed with the top end of the shelf 2 and/or the bottom end of the shelf 2.

When the user rotates the shelf 2 to take out the articles, the box door 12 is closed to finish the taking-out action, the shelf 2 can be turned back to the original position, so that the article placing space is still located in the initial area.

For convenience of use, the user may not return the shelf 2 to the original position after closing the door 12 and completing the removal operation, but there may be two problems:

first, the rest position of the shelf 2 may not correspond to the three divided areas of the case 1, and specifically, the problem of dislocation of the upper side plate 23 of the shelf 2 and the second partition 112 of the top cover 11 is presented.

Secondly, the area where the storage space stays is not suitable for the proper storage temperature of the articles in the storage space.

In view of the first problem, in this embodiment, a specific embodiment for making the stay position of the shelf 2 correspond to the area is provided, as shown in fig. 4 and 5, where there is a magnetic limiting device 7 at the position where the top of the box 1 is matched with the top end of the shelf 2 and/or where the bottom of the box 1 is matched with the bottom end of the shelf 2, where the magnetic limiting device 7 includes a first limiting member 71 located on the box 1 and a second limiting member 72 located on the shelf 2, where: the first limiting piece 71 positioned at the top of the box body 1 and the second limiting piece 72 positioned at the top end of the storage rack 2 are magnetically adsorbed, and/or the first limiting piece 71 positioned at the bottom of the box body 1 and the second limiting piece 72 positioned at the bottom end of the storage rack 2 are magnetically adsorbed, so that the storage rack 2 rotates to a position in sealing contact with the two ends of the box body 1. Specifically, the first limiting member 71 is located on the second partition 112, and the second limiting member 72 is located on the side plate 23 of the shelf 2.

The first limiting member 71 and the second limiting member 72 may be magnets or electromagnets (having magnetism when energized), and at this time, the polarities of the portions of the first limiting member 71 and the second limiting member 72 contacting each other are opposite, so that an adsorption force is generated between the two. Alternatively, the first stopper 71 is a magnet, and the second stopper 72 is a metal member (only the second stopper 72 or the side plate 23 on the shelf 2 is required to be a metal member). When the position where the shelf 2 stays, the second partition 112 and the side plate 23 are not corresponding, since the rotating shaft 21 is rotatable, the first limiting member 71 and the second limiting member 72 can absorb each other, and the object placing plate 22 is pulled to the position where the second partition 112 corresponds to the side plate 23 by using the absorption force, so as to achieve the correspondence of the object placing space and the area, that is, the correspondence of the second partition 112 and the side plate 23.

In view of the second problem, this embodiment provides a specific implementation manner for adjusting the temperature of each area to be matched with the proper temperature of the article on the storage space, and the refrigerator further includes: a temperature adjusting device for adjusting the temperature of the region; an angle detection unit for detecting a rotation angle of the shelf 2; the control unit is connected with the angle detection unit and is used for receiving the angle signal of the angle detection unit and controlling the temperature regulating equipment to enable the temperature of the area where the object placing space is located to be matched with the proper storage temperature of objects in the area.

The control unit can be a control device such as a singlechip, and the calculation of the corresponding area of the rotating angle can be realized by using a computer program coded on a readable medium of the singlechip according to the angle signal transmitted by the angle sensor. In this embodiment, if the initial position is set on the side wall of the storage space in the first area 100, when the angle is within the range of detecting the forward rotation (0 ° and 120 °) of the rack 2, the control unit calculates and determines that the storage space is still located in the first area 100; the control unit calculates and determines that the storage space is located in the second region 200 at this time when the angle penetration detects that the rack 2 is rotated forward (120 °,240 °), and calculates and determines that the storage space is located in the third region 300 when the angle penetration detects that the rack 2 is rotated forward (240 °,360 °).

The real-time temperature of the corresponding region is detected by the temperature sensors respectively located in the first, second and third regions 100, 200 and 300, thereby judging whether the corresponding region has been warmed up or cooled down to the target temperature.

As an alternative embodiment, more than two air channels with refrigeration modules are defined on the box body 1, and each air channel is separately communicated with the corresponding area; the temperature adjustment device includes: the air door 3 is arranged on each air duct and used for adjusting the flow of cold air; and a driving part connected with the air door 3 for adjusting the opening and closing degree of the air door 3. In this embodiment, the control unit controls the operation of the driving component, which may be the motor or the driving cylinder, and the like, which is not described herein.

As an alternative embodiment, the temperature of the area acquired by the temperature detection unit is compared with a set target temperature, wherein: when the temperature of the area is greater than the target temperature, the control unit controls the driving part to operate and increases the opening degree of the air door 3; when the temperature of the area is less than the target temperature, the control unit controls the driving part to operate and reduces the opening degree of the air door 3; when the temperature of the zone is equal to the target temperature, the control unit controls the driving part to stop working and fixes the opening degree of the damper 3. Specifically, if the driving component adopts a motor, the opening degree of the motor forward rotation air door 3 is increased, the cold air flow in the corresponding air duct is increased, and the temperature of the corresponding area is reduced; when the temperature of the area is higher than the target temperature, the control unit controls the motor to rotate positively and increases the opening degree of the air door 3; when the temperature of the area is less than the target temperature, the control unit controls the motor to rotate reversely and reduces the opening degree of the air door 3; when the temperature of the zone is equal to the target temperature, the control unit controls the motor to stop working and fixes the opening degree of the damper 3. The temperature control method in the embodiment realizes the temperature control of multiple areas in the box body 1, and the temperature is controlled in real time along with the position change of the article.

The particular features, structures, or characteristics may be combined in any suitable manner in any one or more embodiments or examples in this specification.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
