For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0038] In addition, the terms "disposed", "connected", and "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0039] Unless otherwise stated, the term "plurality" means two or more.

[0040] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0043] Combination Figure 1 As shown, the embodiment of the present disclosure provides a storage device 10, including a main body 20, a weighing unit 40 and a calibration device 50. The main body 20 defines a storage space 30. The weighing unit 40 is provided on the main body 20, and is used to detect the weight of the items in the storage space 30 and obtain the weight value. The calibration device 50 is connected to the weighing unit 40, and corrects the weight value to obtain the actual weight value.

[0044] With the storage device 10 provided by the embodiment of the present disclosure, after the weighing unit 40 detects the weight of the items in the storage space 30 and obtains the weight value, the weight value is transmitted to the calibration device 50 connected to the weighing unit 40, and the calibration device 50 corrects the received weight value to obtain the actual weight value. In this way, the error of the weight value is reduced through the correction of the calibration device 50, and the weight data of the items in the storage space 30 obtained is more accurate.

[0045] Optionally, the calibration device 50 includes a horizontal correction device 51 and a data processor. The horizontal correction device 51 is used to obtain the angle between the weighing unit 40 and the horizontal plane. The data processor is connected to the horizontal correction device 51 and corrects the weight value according to the received angle information to obtain the actual weight value.

[0046] No matter the placement of the refrigerator or the installation of the weighing unit 40, it is impossible to absolutely guarantee that it is parallel to the horizontal plane. Therefore, the horizontal correction device 51, such as an electronic level, should firstly measure the angle θ between the weighing unit 40 and the horizontal plane, and then the data processor corrects the weight value according to the received angle information to obtain the actual weight value. Figure 2 As shown, the weight value of the article measured by the weighing unit 40 is assumed to be F 1 , then the actual weight of the items in the storage space 30 is G 1 F 1 / cosθ. If there are multiple weighing units 40, for example, four, then the actual weight of the items in the storage space 30 is the sum of the weights of the items shared by each weighing unit 40, that is, G 实 =(F 1 +F 2 +F 3 +F 4 ) / cosθ.

[0047] Optionally, the main body 20 includes a drawer 21 and a slide rail assembly 22. The drawer 21 defines a storage space 30, and the slide rail assembly 22 is slidably connected to the drawer 21. The weighing unit 40 is disposed on the slide rail assembly 22; and / or the calibration device 50 is disposed on the slide rail assembly 22.

[0048] In this way, the weighing unit 40 is arranged on the slide rail assembly 22, and the position of the slide rail assembly 22 is fixed, which can reduce the influence of the sliding of the drawer 21 on the measurement of the weighing unit 40, so that the measurement result is more accurate. It is understandable that, according to actual needs, the weighing unit 40 can also be arranged in the drawer 21. The calibration device 50 is arranged on the slide rail assembly 22, and the position of the slide rail assembly 22 is fixed, which can reduce the influence of the sliding of the drawer 21 on the calibration of the calibration device 50, so that the calibration result is more accurate. It is understandable that, according to actual needs, the calibration device 50 can also be arranged in the drawer 21.

[0049] Optionally, combined Figures 3 to 5 As shown, the rail assembly 22 includes a rail 221, and the drawer 21 can move relative to the rail assembly 22 along the length direction of the rail 221. The position of the drawer 21 relative to the rail assembly 22 includes a first position and a second position. The rail assembly 22 also includes a first contact portion 222 and a second contact portion 223 respectively arranged at both ends of the length direction of the rail 221. When the drawer 21 is in the first position, the first contact portion 222 and the second contact portion 223 both cooperate with the drawer 21; when the drawer 21 is in the second position, one of the first contact portion 222 and the second contact portion 223 cooperates with the drawer 21. The weighing unit 40 includes a first weighing unit 41 arranged at the first contact portion 222 and a second weighing unit 42 arranged at the second contact portion 223.

[0050] In this way, the first weighing unit 41 and the second weighing unit 42 are respectively arranged at the two ends of the length direction of the track 221. In the first position, the first weighing unit 41 and the second weighing unit 42 jointly measure the weight value of the items in the drawer 21; in the second position, one of the first weighing unit 41 and the second weighing unit 42 is used to measure the weight value of the items in the drawer 21, and the other is not in contact with the drawer 21.

[0051] Optionally, the track 221 includes a first track and a second track that are arranged opposite to each other, the first weighing unit 41 includes a weighing unit A and a weighing unit B, and the second weighing unit 42 includes a weighing unit C and a weighing unit D. The weighing unit A and the weighing unit C are respectively arranged at two ends of the length direction of the first track, and the weighing unit B and the weighing unit D are respectively arranged at two ends of the length direction of the second track.

[0052] Assume that the weight of the item measured by weighing unit A is F 1 , the weight value of the item measured by weighing unit B is F 2 , the weight value of the item measured by weighing unit C is F 3 , the weight value of the item measured by weighing unit D is F 4 , then, when the drawer 21 is in the first position, the actual weight of the items in the storage space 30 is the sum of the weights of the items shared by each weighing unit 40, that is, G 实 =(F 1 +F 2 +F 3 +F 4 ) / cosθ; when the drawer 21 is in the second position, only the weighing unit A and the weighing unit B cooperate with the drawer 21, or only the weighing unit C and the weighing unit D cooperate with the drawer 21, then the actual weight value of the items in the storage space 30 is the sum of the weight values ​​of the items shared by the weighing unit A and the weighing unit B, that is, G 实 =(F 1 +F 2 ) / cosθ, or the actual weight of the items in the storage space 30 is the sum of the weights of the items shared by the weighing unit C and the weighing unit D, that is, G 实 =(F 3 +F 4 ) / cosθ.

[0053] It is understandable that when the user powers on for the first time, the weighing unit 40 will perform automatic initial settings. Through initialization, the weighing unit 40 transmits the weight value of the drawer 21 detected when no food is placed therein to the calibration device 50. The calibration device 50 obtains the actual weight value of the drawer 21 when no food is placed therein after correction and marks it as the actual weight value of the drawer 21. In this way, during the subsequent use of the refrigerator, the actual weight value of the drawer 21 can be directly deducted to optimize the data processing process.

[0054] Optionally, the first weighing unit 41 is disposed on a side of the first contact portion 222 facing away from the drawer 21 ; and / or the second weighing unit 42 is disposed on a side of the second contact portion 223 facing away from the drawer 21 .

[0055] In this way, the first weighing unit 41 is arranged on the side of the first contact portion 222 away from the drawer 21, and the friction between the first weighing unit 41 and the drawer 21 can be reduced during the slide of the drawer 21 relative to the rail 221, thereby increasing the service life of the first weighing unit 41. The second weighing unit 42 is arranged on the side of the second contact portion 223 away from the drawer 21, and the friction between the second weighing unit 42 and the drawer 21 can be reduced during the slide of the drawer 21 relative to the rail 221, thereby increasing the service life of the second weighing unit 42.

[0056] The embodiment of the present disclosure provides a refrigerator, comprising a housing and a storage device 10. The housing defines a refrigeration space, and the storage device 10 is disposed in the refrigeration space.

[0057] At present, with the development of intelligent refrigerator design, users' requirements and expectations for refrigerators are getting higher and higher. Users' demand for macro control and fine management of items in refrigerators is increasing day by day. Users hope to understand the internal usage of refrigerators more intuitively and accurately.

[0058] Optionally, in order to facilitate the interaction between the user and the refrigerator, the refrigerator is provided with one or more interactive devices, and there is no restriction on the specific location and number of the interactive devices. In addition, there is no restriction on the specific form of the interactive device, for example, the interactive device can be a voice interactive system, a display interface interactive system, or a combination of the two.

[0059] Specifically, after the user completes the action of storing or taking out food in a storage space 30, the actual weight value of the food in the current storage device 10 is announced by voice and / or the actual weight value of the food in the current storage device 10 is displayed on the display interface interactive system such as a display screen. In this way, the intelligent management of the refrigerator can be strengthened and the user experience can be improved. In addition, in combination with the interactive device, when the interactive device is a visual interactive interface, the user can also understand the weight of the food in each drawer 21 of the refrigerator through the interactive interface. When the refrigerator also includes a food management system, in combination with the food identification system, the location, type and weight information of the food of this type can be understood.

[0060] Optionally, the data in the interactive device is uploaded to the mobile phone software (Application, APP) on the computer or mobile phone via a wireless network or Bluetooth.

[0061] In this way, the weight of the items stored in each storage device 10 can be intuitively displayed in the APP, which improves the user interaction experience and facilitates the user to have a macroscopic control and fine management of the items in the refrigerator. In addition, it lays the foundation and accumulates technical reserves for establishing a more comprehensive and powerful digital model of user home refrigerators in the future.

[0062] Optionally, when the weighing unit 40 senses a change in weight in a drawer 21, such as an increase in weight, the APP can automatically send software push information to the user's mobile phone to remind the user to set corresponding functions, such as reminding the user to set the category of new items placed in, detecting whether to turn on sterilization when new items are placed in, and other linkage functions and scenarios to be developed, effectively increasing the effective interaction opportunities between the APP and users and enhancing the intelligent interactive experience.

[0063] The refrigerator also includes a control module, which is connected to the calibration device to obtain the actual weight value.

[0064] Combination Figure 6 As shown, an embodiment of the present disclosure provides a refrigerator control method for controlling the above refrigerator, the method comprising:

[0065] S01, the control module obtains the actual weight value of the items in the storage space 30 and controls the operation of the refrigerator according to the actual weight value.

[0066] Optionally, the refrigerator includes a plurality of lighting devices, and the control module is connected to the plurality of lighting devices. Obtaining the actual weight value of the items in the storage space 30 and controlling the operation of the refrigerator according to the actual weight value includes:

[0067] In the door open state, the control module obtains the change value of the actual weight value of the items in the storage space 30 within the first preset time;

[0068] If the change value is greater than the first preset change value, the control module controls the lighting device corresponding to the storage space 30 to turn on.

[0069] For example, a refrigerator has multiple drawers 21, and multiple lighting devices are set in one-to-one correspondence with multiple drawers 21. A certain drawer 21 is matched with a slide rail assembly 22, and the above-mentioned four weighing units 40 of A, B, C, and D are arranged on the rail 221. In the open door state, if the change value of the actual weight value of the items in this drawer 21 within 5 seconds is greater than 100 grams, the lighting device corresponding to this drawer 21 is controlled to be turned on; otherwise, the lighting device corresponding to this drawer 21 is turned off. In this way, each drawer 21 is correspondingly provided with a matching weighing unit 40, and the state of this drawer 21 can be obtained according to the change value of the actual weight value of the items in a certain drawer 21, so as to realize accurate control of multiple lighting devices and avoid invalid lighting of some lighting devices. Moreover, the control module can optimize the refrigeration scheme and save electric energy according to the weight data fed back by each drawer 21. It can be understood that it is also possible to judge that the drawer 21 is in the second position, that is, the pulled-out state, according to the disappearance of the reading of a certain weighing unit 40 among the four weighing units A, B, C, and D. At this time, the lighting device corresponding to the drawer 21 is controlled to be turned on.

[0070] Optionally, the refrigerator includes an alarm device, and the control module is connected to the alarm device. Obtaining the actual weight value of the items in the storage space 30 and controlling the operation of the refrigerator according to the actual weight value includes:

[0071] In the door open state, the control module obtains the change value of the actual weight value of the items in the storage space 30 within the second preset time;

[0072] If the change value is less than the second preset change value, the control module controls the alarm device to turn on.

[0073] For example, when the door is open and the opening time exceeds 3 minutes, the change in the actual weight of the items in the storage space 30 is obtained every 5 seconds. If the change is less than 100 grams, it is determined that the user is in a non-operating state, that is, the user forgets to close the door after storing or taking out items. At this time, the alarm device is controlled to turn on to remind the user to close the door in time; otherwise, it is determined that the user is in an operating state, the alarm device is turned off, and / or the acquisition of the change value is suspended for 30 seconds.

[0074] In this way, the user's status can be determined based on the change in the actual weight value of the items in the storage space 30, and the problem of the refrigerator continuing to alarm due to exceeding the set door opening time while the user is still operating the refrigerator can be avoided as much as possible. The refrigerator's door opening alarm control logic is optimized to improve the user experience.

[0075] Optionally, the refrigerator includes a leveling component and / or an alarm device, and the control module is connected to the leveling component, and / or the control module is connected to the alarm device. Controlling the operation of the refrigerator according to the actual weight value includes:

[0076] When the actual weight value is greater than the weight threshold, the control module controls the leveling component to start to level the refrigerator; and / or the control module controls the alarm device to issue a refrigerator tilt warning.

[0077] In this way, when the user places excessively heavy objects and creates a potential safety hazard of tipping over, the user can be alerted of the refrigerator tilting alarm, and / or the leveling component can be controlled to open and level the refrigerator, providing a safety guarantee for the user and reducing the probability of safety accidents.
