Description

Technical Field

[0001] This application relates to the technical field of freezers, for example, to a control method and control device for a freezer, a freezer, and a computer-readable storage medium. Background Art

[0002] Freezers can freeze or preserve items such as food, so they are widely used in commercial applications. Most of the door bodies of current freezers are flip-type door bodies. Due to the large weight of the door body, if you need to take or place items placed near the door body, you need to increase the opening angle of the door body, which will cause the low-temperature storage compartment to be completely exposed to the air, resulting in a large loss of cold.

[0003] Related technologies disclose a refrigeration device, including: a box body, including a pick-up and placement opening provided at the top; a door body assembly, provided at the pick-up and placement opening, including a first door body and a second door body stacked up and down. Both the first door body and the second door body are slidably connected to the box body, and the box body can be opened by sliding the first door body or the second door body left or right; when the door body assembly is in the fully open state, the first door body and the second door body completely overlap in the thickness direction.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related technologies:

[0005] When taking or placing items near the middle position of the box body, the door body assembly needs to be in the fully open state. At this time, the opening area of the door is the largest. Then, the refrigeration compartment inside the box body is still largely exposed to the air, resulting in a large loss of cold. After the door body assembly is closed, it takes a long time to restore the set storage temperature in the compartment, and the energy consumption is high.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application, so it may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0046] Combined with Figure 2 As shown in the figure, an embodiment of the present disclosure provides a control method for a freezer, including:

[0047] S21, the processor obtains the projection position information of the user's hand projected onto the door body assembly.

[0048] S22, the processor determines the target door body according to the projection position information.

[0049] S23, the processor obtains the current distance between the user's hand and the target door body.

[0050] S24, the processor performs corresponding opening and closing operations on the target door body according to the current distance to open or close the target access opening corresponding to the target door body.

[0051] Optionally, an identification module is provided on the door body. The projection position information of the user's hand projected onto the door body assembly is collected through the identification module, so that the area where the user has the intention to open the door can be determined, and then the door body in this area can be determined as the target door body.

[0052] Optionally, an identification module is provided on each door body. When the projection position information is associated with multiple door bodies, the multiple door bodies can be used as target door bodies simultaneously.

[0053] Optionally, a ranging module is provided on each door body for measuring the distance between the user's hand and the target door body. For example, the distance between the user's hand and the target door body can be determined by infrared sensing technology or ultrasonic reflection technology.

[0054] Optionally, in the case of determining the target door body, the current distance between the user's hand and the target door body, that is, the vertical distance between the user's hand and the target door body, can be used as the basis for whether to open the target door body. Further, the user's intention to open the door can be determined according to the current distance. In this way, the user's current purpose can be judged more accurately, so that the refrigerator can obtain accurate control instructions.

[0055] Further, in the case of determining that the user has the intention to open the door, when it is determined that the user needs to open the door body, the instruction to open the target door body is executed. At this time, only the access opening and the storage area corresponding to the target door body are exposed; when it is determined that the user does not need to open the door body, the instruction to keep the target door body closed is executed. At this time, the accidental opening of the target door body can be avoided, so that the loss of cold in the refrigerator caused by the accidental opening of the access opening can be reduced, and the energy consumption can be further reduced.

[0056] By adopting the control method for a freezer provided by the embodiments of the present disclosure, the open mouth of the cabinet body can be divided into multiple access openings by mutually crossing a first partition strip and a second partition strip. Correspondingly, a door body is provided at each access opening, and each door body corresponds to a storage area inside the cabinet body. The door body can be rotated to open the access opening to take out the items stored in the storage area corresponding to the door body. By obtaining the projection position information of the user's hand projected onto the door body assembly, the door body that matches the projection position can be determined as the target door body. Further, according to the current distance between the user's hand and the target door body, it can be determined whether the user has an intention to open the door. When it is determined that the user needs to open the door body, an instruction to open the target door body is executed, and at this time, only the storage area corresponding to the target door body is exposed; when it is determined that the user does not need to open the door body, an instruction to keep the target door body closed is executed, and at this time, the accidental opening of the target door body can be avoided, thereby reducing the loss of cold in the freezer and reducing energy consumption.

[0057] Combined with Figure 3 As shown in the figure, the embodiments of the present disclosure provide a control method for a freezer, including:

[0058] S31, the processor obtains the projection area of the user's hand projected onto the door body assembly and determines the projection center of the projection area.

[0059] S32, the processor obtains the first distance between the projection center and the first border and the second distance between the projection center and the second border.

[0060] S33, the processor determines the projection position information of the projection area according to the first distance and the second distance.

[0061] S34, the processor determines the target door body according to the projection position information.

[0062] S35, the processor obtains the current distance between the user's hand and the target door body.

[0063] S36, the processor performs a corresponding door opening or closing operation on the target door body according to the current distance to open or close the target access opening corresponding to the target door body.

[0064] Optionally, the first border and the second border are vertically arranged, with the first border and the second border as the reference coordinate axes and the connection point between the two as the origin. Therefore, each point on the door body assembly has a coordinate mark, and each door body has a coordinate range. The processor can determine the coordinate value of the projection center through the first distance and the second distance, and then by comparing the coordinate value with the coordinate information of the door body, when the coordinate information of the door body matches the coordinate value of the projection center, it is determined that the door body is the target door body.

[0065] Exemplarily, the first frame extends along the length direction of the cabinet body and can be used as the X-axis; the second frame extends along the width direction of the cabinet body and can be used as the Y-axis. Among them, the door body has 4 vertices, and the coordinates are (X1, Y1), (X2, Y1), (X1, Y2), and (X2, Y2) respectively. When the coordinates of the two planes of the projection center of the user's hand projected onto the projection area of the door body assembly are respectively within [X1, X2] and [Y1, Y2], it can be determined that this door body is the target door body.

[0066] Optionally, when the projection center exactly falls on the first partition bar or the second partition bar, it indicates that the projection area is associated with multiple door bodies. At this time, it is necessary to determine the area of the projection area on each door body, and take the door body with the largest projection area as the target door body. Or, take all the door bodies associated with the projection area as the target door bodies.

[0067] Optionally, the processor determines the target door body according to the projection position information, including: the processor determines the number of the first partition bar adjacent to the projection area according to the projection position information to determine the first number information of the door body corresponding to the projection area; the processor determines the second number information of the door body corresponding to the projection area according to the first number information and the second spacing information; the processor determines the door body that matches both the first number information and the second number information as the target door body.

[0068] By the projection position information, determine the number of the first partition bar adjacent to the projection area, that is, determine the number of the first partition bar with the smallest distance from the projection center, as the first number information of the door body number. Among them, multiple door bodies are arranged on each first partition bar once, and the multiple door bodies are numbered in the direction from near the second frame to far from the second frame, as the second number information of the door body number.

[0069] By the first number information and the second number information, determine the door body that matches both the first number information and the second number information as the target door body, so that the target door body to be opened can be accurately and quickly confirmed, so as to facilitate the freezer to accurately control the target door body.

[0070] Circularly, there are four sides that enclose an opening. In the case of including the first frame and the second frame, it also includes a first partition bar and a first second partition bar. Among them, the first frame is parallel to the first partition bar and their structures are exactly the same, and the second frame is parallel to the second partition bar and their structures are exactly the same.

[0071] In some embodiments, determining the target door body according to the projection information further includes: the processor obtains the current position change amount of the projection center; in the case that the current position change amount is less than the preset change value, the processor determines to keep the current target door body; in the case that the current position change amount is greater than or equal to the preset change value, the processor re-determines the target door body.

[0072] The current position change includes the change of the coordinates. If the current position change is less than the preset change value, the current target door is maintained; if the current position change is greater than or equal to the preset change value, the target door is re-determined.

[0073] Optionally, in order to avoid the target door body being replaced due to movement without replacement intention, in an optimized solution, it is also possible to determine whether to replace the target door body in combination with the retention time of the position change. In other words, the retention time of the position change can be obtained, and when the retention time reaches a preset retention time, it is determined to replace the target door body.

[0074] In some embodiments, according to the current distance, corresponding door opening and closing operations are performed on the target door body, including: when the current distance is less than the preset distance, the processor obtains the length of time the user's hand stays; the processor generates a control instruction for controlling the movement of the door body according to the length of stay, and executes the control instruction.

[0075] Optionally, when the current distance is less than the preset distance, it indicates that the user intends to open the door.

[0076] In order to determine the user's intention to open the door and avoid misoperation, the user's hand can also be combined with the length of time the user's hand stays to determine that the user does have the intention to open the door. In this way, the accuracy of the user's operation intention recognition can be ensured, and operation events that are not intended by the user can be avoided. In addition to effectively preventing the device from being misoperated due to misidentification, avoiding frequent operation command recognition can also help save device processing resources.

[0077] Optionally, a control instruction for controlling the door action is generated according to the dwell time, including: when the dwell time is longer than a preset time, the processor generates a first instruction for opening the target door and executes the first control instruction; or, when the dwell time is longer than a preset time, the processor generates a second instruction for closing the target door and executes the second control instruction. In this way, the user's door opening needs can be judged more accurately.

[0078] Optionally, determining the control instruction of the target door body according to the current distance further includes: generating a second instruction for closing the target door body when the current distance is less than a preset distance, and executing the second control instruction. In this way, the door body can be prevented from being opened by mistake due to misoperation, thereby facilitating the avoidance of cooling loss.

[0079] Combination Figure 5As shown in the figure, an embodiment of the present disclosure provides a control device 50 for a refrigerator, including a first acquisition module 51, a determination module 52, a second acquisition module 53, and an execution module 54.
