Description

Technical Field

[0001] The present invention relates to the technical field of refrigerator control, and particularly to a control method for a refrigerator, a refrigerator, and a computer-readable storage medium. Background Art

[0002] Modern people's lifestyles are becoming increasingly complex and diverse, and cannot be defined by the traditional way of rising with the sun and resting with the sunset. However, many refrigerators only control the operation of each electrical component of the refrigerator through the compartment temperature and a fixed operation mode. However, this operation mode cannot make corresponding changes according to the user's living habits. Summary of the Invention

[0003] In order to solve the technical problem that the operating components of the refrigerator in the above-mentioned prior art cannot be automatically matched according to the user's living habits, the present invention provides a control method for a refrigerator, a refrigerator, and a computer-readable storage medium.

[0004] The technical solution adopted by the present invention is as follows:

[0005] The present invention provides a control method for a refrigerator, including the steps of:

[0006] Presetting n consecutive time periods, recording the total opening duration and the number of opening times of the refrigerator door in each time period, and calculating the data S corresponding to each time period according to a preset algorithm;

[0007] Taking a preset number of days as a collection period, adding the data S of the same time period within the preset number of days to obtain n judgment data Sp corresponding to each time period;

[0008] Judging whether the numerical differences of the n judgment data Sp meet a preset condition. If so, in the next collection period, adjust the gear of the compressor in the time period corresponding to the judgment data Sp according to the numerical size of the judgment data Sp.

[0009] The above-mentioned preset algorithm is: S = A / s + B, where A is the total opening duration of the refrigerator door, B is the number of opening times of the refrigerator door, and s is a preset value.

[0010] The above-mentioned preset condition is: sorting the n judgment data Sp from large to small, the maximum value of the n judgment data Sp is greater than z times the minimum value, and the sum of the judgment data Sp in the front 1 / 3 is greater than the sum of the judgment data Sp in the back 2 / 3, where the value of z is 4 to 6.

[0011] Further, adjusting the compressor gear in the time period corresponding to the judgment data Sp according to the numerical value of the judgment data Sp specifically includes: sorting the n judgment data Sp from largest to smallest and equally dividing them into multiple parts, increasing the compressor gear in the time period corresponding to the first part of the judgment data Sp; decreasing the compressor gear in the time period corresponding to the last part of the judgment data Sp, and operating the compressor in the time periods corresponding to the remaining parts of the judgment data Sp according to the original control of the refrigerator.

[0012] Preferably, after sorting the n judgment data Sp from largest to smallest, they are equally divided into three parts.

[0013] Specifically, if not, operate according to the original control of the refrigerator.

[0014] Further, when operating according to the original control of the refrigerator, start the next acquisition cycle after delaying the preset time.

[0015] Specifically, the duration of n consecutive time periods is set to the duration of one day.

[0016] The present invention also proposes a refrigerator, including controlling the compressor gear of the refrigerator by the above-mentioned refrigerator control method.

[0017] The present invention also proposes a computer-readable storage medium for storing a computer program, and when the computer program runs, it executes the above-mentioned refrigerator control method.

[0018] Compared with the prior art, the present invention can match the actual usage habits of users to change the compressor gear in the next acquisition cycle, so that the compressor gear matches the actual usage of users, that is, ensuring sufficient refrigeration capacity during the peak usage period and saving energy during the low usage period. It can also reasonably arrange the defrosting time to prevent the refrigerator from being opened when the user is using it, affecting the defrosting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required for use in the embodiments or the description of the prior art. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0020] Figure 1 It is a flowchart in the embodiments of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the following further details the present invention with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Modern people's lifestyles are becoming increasingly complex and diverse, and cannot be defined by the traditional pattern of rising with the sun and resting with the sunset. However, many refrigerators only control the operation of each electrical component of the refrigerator through the compartment temperature and a fixed operation mode. However, this operation mode cannot make corresponding changes according to the user's living habits. Moreover, other existing data collection methods usually require the use of cloud computing for collection. Therefore, it is necessary to add a networking device to the controller, which has high requirements for the controller and increases a large amount of cost. At the same time, data collection can only be carried out when connected to the network during operation. The data needs to be uploaded to the cloud big database, and big data feedback data is required during operation. Once the network is disconnected, it cannot work. The networking operation is complex and the user usability is low. While the present invention only needs to collect data and perform data conversion, and divide the high-usage time period and low-usage time period through the collected data, so as to allocate the appropriate operation time for each electronic device to help users use it better. It does not require networking, and a simple control chip can also be used for control.

[0024] As Figure 1 shown, the present invention proposes a control method for a refrigerator, including the steps of:

[0025] Preset n consecutive time periods, the total duration of the n time periods is one day, that is, 24 hours, record the total duration and the number of openings of the refrigerator door in each time period, and calculate the corresponding data S for each time period according to a preset algorithm;

[0026] Taking a preset number of days as a collection cycle, add the data S of the same time period within the preset number of days to obtain n judgment data Sp corresponding to each time period. Assuming that the preset number of days is 3 days, then collect 3 groups of S1, S2,..., Sn, add the S1 of 3 days to get Sp1, add the S2 of 3 days to get Sp2,..., add the Sn of 3 days to get Spn;

[0027] Judge whether the numerical differences of the n judgment data Sp meet the preset conditions. If so, start the next collection cycle, and within the next collection cycle, adjust the gear of the compressor in the time period corresponding to the judgment data Sp according to the numerical size of the judgment data Sp; if not, operate according to the original control of the refrigerator. Thus, it can match the actual usage habits of users to change the gear of the compressor in the next collection cycle, so that the gear of the compressor matches the actual usage situation of users, and prevent the food in the refrigerator from being affected by temperature fluctuations. Through this control method, that is, ensuring sufficient refrigeration capacity during the peak usage period, and saving energy during the low usage period. It can also reasonably arrange the defrosting time to prevent the refrigerator from being opened when the user is using it, affecting the defrosting effect, and at the same time, the refrigeration effect is low during defrosting, which may cause users to doubt the product quality after discovery.

[0028] In a specific embodiment of the present invention, the above preset algorithm is: S = A / s + B, where A is the total duration of the door opening, B is the number of door openings, s is a preset value, and s can be specifically set to 30, with the unit of seconds. Since the influence of the door opening duration on the cold quantity of the refrigerator is different, it can be bounded by every 30 seconds.

[0029] The above preset condition is: arranging n judgment data S p in descending order, and the sum of the judgment data S in the front 1 / 3 p is greater than the sum of the judgment data S in the back 2 / 3 p , and the maximum value among the n judgment data S p is greater than z times the minimum value, where the value of z ranges from 4 to 6. In this embodiment, z is specifically taken as 5, that is, the maximum value among the n judgment data S p is greater than 5 times the minimum value. When both of these two conditions are met, it indicates that the internal difference of the data values is large, proving that the user's work and rest pattern is to use the refrigerator at a fixed time every day. Corresponding control logic can be provided for the operation of the next acquisition cycle of the refrigerator.

[0030] Adjusting the gear of the compressor in the corresponding time period of the judgment data Sp according to the numerical size of the judgment data Sp is specifically: arranging n judgment data S p in descending order and equally dividing them into multiple parts. Increasing the gear of the variable frequency compressor in the corresponding time period of the first part of the judgment data S p (increasing one gear relative to the original gear, or increasing the preset frequency); reducing the gear of the compressor in the corresponding time period of the last part of the judgment data S p (reducing one gear relative to the original gear, or reducing the preset frequency), and the compressors in the corresponding time periods of the remaining parts of the judgment data S p operate according to the original control of the refrigerator.

[0031] In a specific embodiment, arranging n judgment data S p in descending order and equally dividing them into three parts. Increasing the gear of the variable frequency compressor in the corresponding time period of the first part of the judgment data S p (increasing one gear relative to the original gear, or increasing the preset frequency); reducing the gear of the compressor in the corresponding time period of the third part of the judgment data S p (reducing one gear relative to the original gear, or reducing the preset frequency), and the compressors in the corresponding time periods of the second part of the judgment data S p operate according to the original control of the refrigerator.

[0032] If not, when operating according to the original refrigerator control, the next acquisition cycle starts after a preset time delay, which can specifically be n / 2. That is, originally, the acquisition starts at 2 o'clock every day as the first time period and continues until 2 o'clock the next day to complete the acquisition of n time periods. Delaying by one hour means starting the acquisition at 3 o'clock and continuing until 3 o'clock the next day to complete the acquisition of n time periods.

[0033] The present invention also proposes a refrigerator that uses the above control method to control the compressor gear of the refrigerator.

[0034] If the refrigerator has an internet connection function, the data acquisition can be uploaded to the cloud for storage to prevent data loss in case of power failure.

[0035] The present invention also proposes a computer-readable storage medium for storing a computer program, and when the computer program runs, it executes the control method of the above refrigerator.

[0036] Through this control method, sufficient cooling capacity is ensured during peak usage periods, and energy is saved during off-peak usage periods. It is also possible to reasonably arrange the defrosting time to prevent the refrigerator from being opened when the user is using it, which may affect the defrosting effect. At the same time, the refrigeration effect is low during defrosting, which may cause the user to doubt the product quality after discovery.

[0037] It should be noted that the terms used above are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0038] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that for the sake of convenience of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0039] In the description of the present application, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary explanation, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0040] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used here to describe the spatial positional relationship of a device or feature shown in the drawings with other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0041] In addition, it should be noted that the use of words such as "first", "second" etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present application.
