Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of refrigerators, and in particular to a refrigerator control method, a refrigerator device, a refrigerator equipment, and a storage medium. Background Art

[0002] At present, most medical refrigerators on the market use transparent glass door design, which is to facilitate users to observe the storage of medicines inside the refrigerator. The transparent glass door is usually two or three layers of glass, with a certain gap between the glass and filled with inert gas. However, due to the small thickness and large thermal conductivity of the transparent glass door, and the large temperature difference between the temperature inside the refrigerator and the external environment, condensation is prone to occur on the inner surface of the glass door. In order to prevent condensation on the glass door, the outer surface of the transparent glass door or the surface of the middle layer of glass is usually coated and heated. Heating wires are also arranged on the frames around the glass door. When the refrigerator is powered on, the heating wires work synchronously to make the surface temperature of the glass door higher than the dew point temperature to prevent condensation on the glass surface.

[0003] In the prior art, the glass door heating wire of a refrigeration appliance with a transparent glass door is usually set to a mode of continuous heating or set to a fixed power-on rate control, and it cycles continuously according to this cycle; the setting of the heater power-on rate is usually to place the appliance in a relatively stable working condition in a laboratory and conduct a no-load operation test to verify whether the set power-on rate is appropriate. However, in actual user use, the ambient temperature and humidity are constantly changing. Therefore, if the heating wire works for too short a time, it will usually cause condensation in a high temperature and high humidity environment due to insufficient heat generation; if the heating wire works for too long, it will cause the surface temperature of the glass door to be much higher than the dew point temperature of the environment due to excessive heat generation, which increases the heat load of the refrigerator, affects the uniformity of the temperature inside the box, and is not conducive to power consumption. Therefore, how to accurately control the anti-condensation of the glass door of the refrigerator has become a problem that needs to be solved urgently. Summary of the invention

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] To facilitate understanding of the embodiments of the present invention, specific embodiments will be further explained below in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present invention.

[0050] Figure 1 A flow chart of a refrigerator control method provided by an embodiment of the present invention is shown as follows: Figure 1 As shown, the method specifically includes:

[0051] S11. When the refrigerator is turned on, the heater on the transparent window of the refrigerator is controlled to turn on.

[0052] The refrigerator control method provided in the embodiment of the present invention is applied to refrigerator equipment, which may include but is not limited to: medical refrigerators, portable refrigerators, etc. The refrigerator is provided with a transparent window, which may be a window made of glass, and may be provided on the door body of the refrigerator in the form of a window or a door body (for example, a glass door of the refrigerator), or may be provided at any position of the box body. The transparent window is used for the user to observe the state of the items in the refrigerator, and the specific position of the transparent window in the refrigerator may be set according to the angle at which the user needs to observe the items. Since it is necessary to ensure that condensation does not occur on the transparent window made of glass, this embodiment can control the refrigerator heater by the brightness changes of multiple images taken on the transparent window of the refrigerator, so as to handle the condensation phenomenon of the transparent window of the refrigerator through the heater.

[0053] In this embodiment, the heater is arranged around the transparent window and connected to the heating wire. The heating wire can be arranged at a preset position around the transparent window. The heating wire can be heated and controlled by the heater. The condensation phenomenon on the transparent window made of glass can be eliminated by the heating wire. (For example, when the transparent window is a glass door of a refrigerator, a transparent conductive film is attached to the surface of the glass door, and conductive magma is provided at both ends to connect to the power lead wire. At the same time, heating wires are provided around the door frame and connected in parallel with the heater on the door glass.)

[0054] When the refrigerator is turned on, or after a preset period of time, the heater is controlled to turn on and run according to the preset initial on-off rate and initial heating gear. The on-off rate refers to the ratio of the heater on time to the total running time (for example, the heater is on for 30 seconds and off for 30 seconds, that is, the on-off rate is 50%), and the heating gear can represent the heating temperature of the heater.

[0055] S12. Acquire multiple window images of the cold storage box at intervals of a preset time period.

[0056] In this embodiment, during the operation of the heater, whether condensation is likely to occur is determined once every preset time period (for example, 5 minutes), and a window image of the transparent window is acquired at a preset shooting time within each preset time period to obtain multiple window images corresponding to the preset time period, which are used to determine whether condensation occurs within the current time period.

[0057] Specifically, the total number of window images that need to be acquired in a preset time period can be pre-set, and the total duration of the preset time period can be obtained. The time interval for each window image capture can be determined based on the total duration and the total number, and then the capture time of each time can be determined, and multiple window images can be captured according to the capture time.

[0058] For example, the preset time period is 5 minutes, the preset total number of window images is 10, the image capture time interval is 30 seconds, and a window image is acquired every 30 seconds starting from the current moment.

[0059] S13, controlling the heater according to brightness changes of the plurality of window images.

[0060] In this embodiment, since multiple window images are taken according to time, the brightness of the multiple window images is compared in chronological order to determine whether they are gradually getting brighter or darker. As the brightness change situation, when the brightness change situation indicates that the window image is gradually getting darker, it means that condensation may occur at present. At this time, the on-off rate of the heater is controlled to increase, and / or the heating gear of the heater is controlled to increase, so as to eliminate the condensation phenomenon. When the brightness change situation indicates that the window image is gradually getting brighter or the brightness remains unchanged, it means that no condensation occurs at present, or the current condensation phenomenon is in the process of being eliminated. At this time, the on-off rate of the heater is controlled to decrease, and / or the heating gear of the heater is controlled to decrease, so as to maintain the current state.

[0061] In one possible implementation, when the brightness change indicates that the brightness of the window image remains unchanged, it is determined whether the current brightness of the window image is greater than a preset brightness value. When it is greater than the preset brightness value, it indicates that no condensation phenomenon has occurred. At this time, the heater on-off rate is controlled to be reduced to the minimum and / or the heater heating gear is controlled to be reduced to the minimum, or the heater is directly turned off to save power and avoid overheating. When the current brightness of the window image is less than or equal to the preset brightness value, it indicates that condensation phenomenon has occurred, but the condensation phenomenon cannot be eliminated due to the low degree of heating. At this time, the heater on-off rate is controlled to increase or rise to the highest value and / or the heater heating gear is controlled to increase or rise to the highest value, so as to quickly eliminate the condensation phenomenon.

[0062] The refrigerator control method provided by the embodiment of the present invention controls the heater on the transparent window of the refrigerator to turn on when the refrigerator is turned on; obtains multiple window images of the refrigerator at intervals of a preset time period; and controls the heater according to the brightness changes of the multiple window images. Thus, the refrigerator heater can be controlled according to the brightness changes of the multiple images of the transparent window of the refrigerator taken, so as to handle the condensation phenomenon of the transparent window of the refrigerator through the heater, thereby preventing the condensation from occurring on the transparent window of the refrigerator in advance and quickly eliminating the condensation phenomenon when it occurs.

[0063] Figure 2 A flow chart of another method for controlling a refrigerator provided by an embodiment of the present invention is shown as follows: Figure 2 As shown, the method specifically includes:

[0064] S21. When the refrigerator is turned on, the heater on the transparent window of the refrigerator is controlled to turn on.

[0065] S22. Acquire multiple window images of the cold storage box at intervals of a preset time period.

[0066] In this embodiment, step S21 and step S22 are similar to step S11 and step S12, and the details can be referred to Figure 1 For the sake of brevity, the relevant content will not be elaborated here.

[0067] S23, obtaining brightness information of the same pixel in each of the window images.

[0068] In this embodiment, the brightness of the pixels at multiple preset positions in each window image is obtained as the quality information. The preset positions in each window image are the same, so each pixel in each window image is one-to-one corresponding, and the brightness changes between the corresponding multiple pixels can be compared.

[0069] S24, comparing the brightness information of the corresponding pixels in each of the window images to obtain the brightness change.

[0070] In this embodiment, since each window image acquires the brightness information of the pixel points at the same position, the brightness of the corresponding pixel points at the same position in two adjacent window images is compared, and the brightness change trend of all window images is determined as the brightness change situation. The specific method for determining the brightness change situation includes:

[0071] S241, obtaining the shooting time of each window image, wherein the time interval between two adjacent shooting times is within a preset threshold range;

[0072] S242, sorting the plurality of window images according to the position of each of the shooting moments within the preset time period;

[0073] S243, comparing brightness information of two sorted adjacent window images to obtain a comparison result between multiple adjacent window images;

[0074] S244, when the comparison results greater than the preset number are brightness increase, determining that the brightness change is brightness increase;

[0075] S245, when the comparison results greater than the preset number are brightness reduction, determining that the brightness change is brightness reduction;

[0076] S246: When the comparison results less than or equal to the preset number are that the brightness increases, and the comparison results less than or equal to the preset number are that the brightness decreases, determine that the brightness change is constant.

[0077] In this embodiment, steps S241-S246 are described uniformly, and the time interval of each shooting moment within a preset time period is set in advance according to the number of window images that need to be shot, and the time interval between two adjacent shooting moments is within a preset threshold range (for example, the shooting time interval is 30-60 seconds) to ensure that the shooting time interval is moderate and can clearly reflect the brightness change. The shooting moments of each window image are sorted in the order of their positions within the preset time period. After sorting, the brightness of corresponding pixels in two adjacent window images are compared in the sorting order. Every two adjacent window images are a group, and comparison results between multiple groups of window images are obtained, and the comparison results include: reduced brightness, increased brightness, and unchanged brightness.

[0078] Furthermore, the number of different comparison results is counted. When the comparison result shows that the number of brightness increases is greater than the preset number, it means that the current transparent window is in a state of increased brightness for most of the time within the preset time period, and the brightness change is determined to be increased brightness. When the comparison result shows that the number of brightness decreases is greater than the preset number, it means that the current transparent window is in a state of decreased brightness for most of the time within the preset time period, and the brightness change is determined to be decreased brightness. When the comparison result shows that the number of brightness increases is less than or equal to the preset number, and the comparison result shows that the number of brightness decreases is less than or equal to the preset number, it means that the current brightness change is small, and the brightness change is determined to be unchanged brightness.

[0079] In a possible implementation, the brightness change may also be determined in the following manner:

[0080] The first image of the first window taken within a preset time period and the last image of the second window taken within a preset time period are obtained; when the brightness of the first window image is less than the brightness of the second window image, and the brightness difference is greater than a first threshold, it is determined that the brightness change is an increase in brightness; when the brightness of the first window image is greater than the brightness of the second window image, and the brightness difference is greater than the first threshold, it is determined that the brightness change is a decrease in brightness; when the brightness difference is less than or equal to the first threshold, it is determined that the brightness change is a constant brightness.

[0081] S25. Determine whether condensation occurs on the transparent window according to the brightness change.

[0082] In this embodiment, the decrease in brightness indicates that condensation is occurring or is about to occur on the current transparent window, and the increase in brightness indicates that condensation is not occurring or is disappearing on the current transparent window. The specific judgment method includes:

[0083] When the brightness change is that the brightness of the window image decreases, it is determined that condensation occurs on the transparent window; when the brightness change is that the brightness of the window image increases or remains unchanged, it is determined that the condensation does not occur on the transparent window.

[0084] S26. Control the on / off rate of the heater according to the judgment result.

[0085] In this embodiment, when condensation occurs, the condensation needs to be eliminated by a heater. Specifically, the condensation can be eliminated by increasing the on-off rate of the heater or increasing the heating gear of the heater. Specifically, the condensation can be eliminated by heating. The following steps may be included:

[0086] S261, when the judgment result is that condensation occurs, controlling the on-off rate of the heater to increase, and the on-off rate is negatively correlated with the brightness of the window image;

[0087] S262, when the judgment result is that no condensation occurs and the brightness change condition is that the brightness remains unchanged, controlling the heater to maintain the current on-off rate;

[0088] S263. When the judgment result is that condensation does not occur and the brightness change is that the brightness increases, the on-off rate of the heater is controlled to decrease.

[0089] In this embodiment, steps S261-S263 are described uniformly. When condensation occurs, the on-off rate of the heater is controlled to increase. The specific value of the increased on-off rate can be determined according to the brightness of the last window image taken. The higher the brightness, the lower the value of the increased on-off rate, and the lower the brightness, the higher the value of the increased on-off rate. The brightness change is continuously monitored. When the brightness change monitored subsequently is still a decrease in brightness, the on-off rate continues to be increased. When condensation does not occur, it is further determined whether the brightness increases or remains unchanged. If it remains unchanged, the current on-off rate can be maintained, or the on-off rate can be reduced. When condensation does not occur and the brightness increases, it is not necessary to eliminate the condensation at this time, and the on-off rate can be reduced.

[0090] In one possible implementation, when the on-off rate reaches a maximum value and the operating time is greater than a preset time threshold, the brightness change rate is obtained; when the brightness change rate is less than the preset change rate threshold, a prompt message is generated to prompt the user through the prompt message.

[0091] When the on-off rate has reached the highest value and has been running for a period of time, the brightness change rate within the preset time period is obtained. The brightness change rate can be obtained by dividing the measured difference between two moments within the preset time period by the time interval between the two moments. If the brightness change rate is less than the preset change rate threshold, it means that the condensation may have been eliminated and there is no condensation phenomenon at present, or a fault may occur at present. Therefore, even if the highest on-off rate is used, the condensation cannot be eliminated. At this time, a prompt message is generated and displayed to the user through the display area of ​​the refrigerator or sent to the terminal bound to the refrigerator to prompt the user that the condensation may be eliminated or a fault may occur. It is also possible to further determine whether the brightness of the current window image is greater than the first brightness threshold when the brightness change rate is less than the preset change rate threshold. The first brightness threshold indicates that the brightness has reached the maximum range. If so, a prompt message indicating that the condensation has been eliminated is generated. If the brightness of the current window image is less than or equal to the first brightness threshold, it means that the current brightness has not reached the maximum range and a fault may occur, so a prompt message indicating a fault is generated.

[0092] As an example, Figure 5The figure shows a flow chart of another refrigerator control method provided by an embodiment of the present invention. The transparent window is a glass door of the refrigerator, and a camera arranged in the refrigerator continuously obtains multiple real-time window images of the glass door, sorts the window images in the order of shooting time, selects one of the multiple images as the first image, selects an image with an interval time of more than 30 seconds and less than 60 seconds with the previous image as the next image, until multiple images with a first preset number value are selected, and the multiple images are used as images for judging whether the glass door has condensation. Determine whether foggy condensation occurs on the glass door based on the brightness of the acquired multiple images; when the refrigerator is powered on for the first time, the glass door heater is controlled according to the set minimum on-off rate; during the operation of the refrigerator, determine whether condensation occurs on the glass door, first determine the brightness change of the multiple images after sorting, and when the brightness of the corresponding multiple pixel points in the multiple images gradually decreases, it means that the glass door has signs of condensation, and the on-off rate of the glass door heater is increased; if the difference in brightness between the two is within the set range, it means that there is no sign of condensation on the glass door, and the current on-off rate of the glass door heater is maintained. If condensation already occurs on the glass door of the refrigerator, the glass door heater is immediately controlled according to the set maximum on-off rate to quickly eliminate the condensation. Optionally, for glass doors with condensation, the on-off rate of the glass door heater is generally 100%. Continue to obtain the image of the glass door in real time, and judge whether the condensation phenomenon of the glass door has been eliminated according to the brightness of the image. When the condensation phenomenon of the glass door has been eliminated, according to the real-time judgment, continuously reduce the on-off rate of the glass door heating wire until the set minimum on-off rate is reached.
