The present embodiment will be described in detail with reference to the air cooling method as an example, and those skilled in the art should be able to fully develop the present embodiment for other cooling methods, which are not shown herein.
Fig. 2 is a schematic diagram of a refrigerator 10 according to one embodiment of the present invention.
A storage compartment 111 may be formed inside the inner container. The number and temperature zones of the storage compartments 111 may be arbitrarily set according to actual needs, and in this embodiment, the storage compartments 111 may be multiple, and may include a refrigeration compartment, a freezing compartment, and/or a temperature-changing compartment, for example. The sealed storage container 130 may be provided in the storage compartment 111, for example, may be provided in a refrigerator compartment. The air duct assembly 120 may include an air duct cover that defines an air duct with the inner bladder. The heat exchange air flow exchanging heat with the evaporator may flow through the air duct and into the storage compartment 111. The air duct assembly 120 may be disposed at one side of the sealed storage container 130, for example, the air duct assembly 120 may be disposed at the rear side of the storage compartment 111. That is, the hermetic container 130 may be located at the front side of the air duct assembly 120. Here, the terms "front", "rear", and the like used to indicate the orientation are relative to the actual usage state of the refrigerator 10.
Fig. 3 is a schematic view of the duct assembly 120, the adjusting device 200, and the hermetic container 130 in the refrigerator 10 according to one embodiment of the present invention.
The hermetic container 130 is movably disposed with respect to the air duct assembly 120. The closed storage container 130 may be a drawer, and a moisture permeable device may be disposed on a top wall thereof to allow water vapor from the outside of the closed storage container 130 to pass through in a single direction, so as to adjust the relative humidity inside the closed storage container 130. The moisture permeable means may be a moisture permeable film. In this embodiment, the sealed storage container 130 may be a wet area drawer, and the inside of the sealed storage container has a relatively high relative humidity (e.g., up to%), so as to provide a suitable low-temperature and high-humidity storage environment for food materials such as fruits and vegetables.
The adjusting device 200 may be disposed in the storage compartment 111 for adjusting a distance between the sealed storage container 130 and the air channel assembly 120. One end of the adjusting device 200 is connected to the sealed storage container 130, and is used to drive the sealed storage container 130 to move relative to the air duct assembly 120, so as to adjust the distance between the sealed storage container 130 and the air duct assembly 120.
The adjustment device 200 may include a motor 210 and a transmission assembly. The motor 210 may be a micro stepping motor 210. The motor 210 may be disposed on the air duct cover, for example, may be fixed on a side of the air duct cover facing the sealed storage container 130.
The drive assembly may have a drive shaft 221 and a drive sleeve 222 threaded with each other. Wherein, the transmission shaft 221 can be in transmission connection with the output shaft 211 of the motor 210 to rotate under the driving of the motor 210. The drive shaft 221 may be generally screw-shaped with an external thread formed thereon.
The transmission sleeve 222 may be sleeved on the transmission shaft 221 and fixedly connected to the sealed storage container 130, for example, the transmission sleeve 222 may be fixed on a wall surface of the sealed storage container 130 facing the air duct cover plate. In this embodiment, the driving sleeve 222 may be substantially hollow cylinder, and an internal thread matching with the driving shaft 221 is formed inside the driving sleeve. When the transmission shaft 221 is driven by the motor 210 to rotate, the screwing depth of the transmission shaft 221 in the transmission sleeve 222 can be adjusted, so as to drive the sealed storage container 130 to move relative to the air duct assembly 120.
Fig. 4 is another schematic view of the air duct assembly 120, the adjusting device 200, and the hermetic container 130 in the refrigerator 10 shown in fig. 3.
In this embodiment, one end of the transmission shaft 221 is used for being fixedly connected with the output shaft 211 of the motor 210, and the other end is used for being screwed from the transmission sleeve 222 back to the side of the sealed storage container 130. A first concave part 312 is formed on one side of the transmission sleeve 222 back to the sealed storage container 130, a first convex part 311 can be correspondingly formed at one end of the transmission shaft 221 for screwing in the transmission sleeve 222, and the first convex part 311 can be in clamping fit with the first concave part 312 to prevent the transmission shaft 221 from being separated from the transmission sleeve 222.
In some alternative embodiments, the configuration of the transmission assembly is changed. For example, the drive shaft 221 may be omitted. The output shaft 211 of the motor 210 may be formed with external threads and may be threadedly coupled with the transmission sleeve 222. The sealed storage container 130 can be driven to move by adjusting the screwing depth of the output shaft 211 of the motor 210 in the transmission sleeve 222.
Fig. 5 is a schematic view of the air duct assembly 120 and the adjusting apparatus 200 in the refrigerator 10 according to another embodiment of the present invention, and fig. 6 is a schematic view of a partial structure of the air duct assembly 120 and the adjusting apparatus 200 in the refrigerator 10 shown in fig. 5.
In other alternative embodiments, another transformation may be made to the structure of the transmission assembly. For example, the transmission shaft 221 of the transmission assembly may be provided as an inner shaft 221a and an outer shaft 221b sleeved with each other, and the outer shaft 221b is threadedly sleeved on the inner shaft 221 a. The inner shaft 221a may be in transmission connection with the output shaft 211 of the motor 210, and has an external thread formed thereon. The outer shaft 221b may have a substantially hollow cylindrical shape, and an inner wall of the cylindrical body is formed with an internal thread that engages with the inner shaft 221a, and an outer wall of the cylindrical body is formed with an external thread that engages with the transmission sleeve 222.
Under the power of the motor 210, the inner shaft 221a is driven by the output shaft 211 to rotate, so that the depth of the inner shaft 221a screwed into the outer shaft 221b can be adjusted. When the inner shaft 221a is screwed out of the outer shaft 221b (as shown in fig. 5), the end of the inner shaft 221a facing away from the output shaft 211 and the end of the outer shaft 221b facing toward the output shaft 211 can be clamped and fixed, so that the inner shaft 221a and the outer shaft 221b are connected into a whole, and the outer shaft 221b can be screwed into the transmission sleeve 222 with the inner shaft 221 a.
Fig. 7 is a schematic view of the outer shaft 221b of the driving shaft 221 of the driving assembly of the adjusting device 200 in the refrigerator 10 shown in fig. 5.
The end of the inner shaft 221a facing away from the output shaft 211 may be formed with a second protrusion 321, the end of the outer shaft 221b facing toward the output shaft 211 may be formed with a second recess 322, and the second protrusion 321 may be snap-fitted with the second recess 322, so that the inner shaft 221a and the inner shaft 221a are fixedly connected. A first concave part 312 is formed on one side of the transmission sleeve 222 back to the sealed storage container 130, a third convex part 331 is correspondingly formed at one end of the outer shaft 221b for screwing into the transmission sleeve 222, and the third convex part 331 can be in clamping fit with the first concave part 312 to prevent the outer shaft 221b from being separated from the transmission sleeve 222.
The transmission shaft 221 is provided with the inner shaft 221a and the outer shaft 221b which are sleeved with each other, which is not only beneficial to increasing the adjustment length of the transmission shaft 221, but also beneficial to saving the space occupied by the transmission shaft 221, so that the adjusting device 200 can obtain a larger adjusting range by using a limited space, thereby expanding the moving range of the sealed storage container 130, improving the humidity conditioning capability of the refrigerator 10 and relieving the condensation problem.
The adjusting device 200 of the present embodiment has a simple structure and a low manufacturing cost, so that the refrigerator 10 of the present embodiment can realize a function of automatically alleviating the condensation problem with a simple structure. In addition, when the adjusting device 200 adjusts the distance between the sealed storage container 130 and the air duct assembly 120, friction can be reduced through unidirectional force transmission, which is beneficial to prolonging the service life of the motor 210.
The processor 410 and the memory 420 may form a control device of the refrigerator 10. Wherein the memory 420 stores therein a control program 421, and the control program 421 is used to implement the control method of the refrigerator 10 according to any one of the following embodiments when executed by the processor 410. The processor 410 may be a Central Processing Unit (CPU), or a digital processing unit (DSP), etc. The memory 420 is used to store programs executed by the processor 410. The memory 420 may be any medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited to such. Memory 420 may also be a combination of various memories 420. Since the control program 421 is executed by the processor 410 to implement the processes of the method embodiments described below and achieve the same technical effects, the detailed description is omitted here to avoid repetition.
In this embodiment, the refrigerator 10 may further include an image capturing device for capturing images and/or dynamic videos of the inner wall of the sealed storage container 130. By analyzing the images and/or dynamic videos of the inner wall of the closed storage container 130, the condensation amount of the closed storage container 130 and the diameter of the condensed dew on the surface of the closed storage container 130 can be determined. The image acquisition device may include an image acquirer and/or an AI intelligent recognition system. The image collector may be at least one camera for capturing images and/or dynamic videos of the inner wall of the sealed storage container 130. The image acquisition device can process the images and/or dynamic videos shot by the image acquirer by using an AI intelligent recognition system, so that the condensation amount of the closed storage container 130 and the diameter of dew condensed on the surface of the closed storage container 130 are recognized. For example, based on the AI intelligent recognition system, feature extraction may be performed on images and/or dynamic videos, and the dew amount of the sealed storage container 130 and the diameter size of dew condensed on the surface of the sealed storage container 130 may be obtained by using dew feature recognition based on deep learning. In other embodiments, the refrigerator 10 may also be connected with an external AI intelligent recognition system in advance, for example, images and/or dynamic videos captured by an image collector may be transmitted to the external AI intelligent recognition system, so as to analyze the condensation amount and the dew diameter by using the external AI intelligent recognition system, which is beneficial to reduce the hardware cost of the refrigerator 10.
The condensation amount may refer to an amount of water condensed on the inner wall of the closed storage container 130.
In some alternative embodiments, the refrigerator 10 may include a condensation sensor for detecting the amount of condensation of the hermetic container 130. The condensation sensor may be disposed on an inner wall of the closed storage container 130, and when condensation is generated on the inner wall of the closed storage container 130, a specific current signal may be generated inside the condensation sensor, and the current signal may be changed according to a change of the amount of the condensation. The condensation amount can be determined by collecting the current signal of the condensation sensor.
In other alternative embodiments, the refrigerator 10 may include a humidity sensor for detecting absolute humidity and/or relative humidity within the sealed storage container 130. By analyzing the absolute humidity within the sealed storage container 130, the amount of condensation of the sealed storage container 130 may be indirectly determined.
Fig. 8 is a schematic diagram of a control method of the refrigerator 10 according to one embodiment of the present invention. The control method may generally include:
step S802, the condensation amount of the sealed storage container 130 is acquired. The condensation amount of the sealed storage container 130 may refer to an amount of water condensed on the inner wall of the sealed storage container 130, and may refer to parameters such as volume or mass of water condensed on the inner wall per unit area, for example.
In step S804, the closed storage container 130 is controlled to move relative to the air duct assembly 120 according to the condensation amount. That is, the interval between the hermetic container 130 and the air duct assembly 120 is adjusted according to the amount of condensation, thereby adjusting the temperature of the hermetic container 130.
With the method described above, after the refrigerator 10 of the present embodiment obtains the amount of condensation of the hermetic container 130, the refrigerator 10 of the present embodiment can control the movement of the hermetic container 130 relative to the air duct assembly 120 according to the amount of condensation. By adjusting the distance between the sealed storage container 130 and the air duct assembly 120, the temperature of the sealed storage container 130 can be adjusted, so that the refrigerator 10 of the invention can automatically alleviate the condensation problem, prevent the condensation problem from worsening, and improve the intelligent degree.
The step S802 may include: an image of the sealed storage container 130 is acquired, and the amount of condensation is determined from the image of the sealed storage container 130. For example, in the case that the closed time period of the refrigerator 10 exceeds a first preset time period, the image capture device may be controlled to capture an image of the closed storage container 130 to determine whether condensation is generated in the closed storage container 130, to determine whether the closed storage container 130 needs to be moved relative to the air duct assembly 120, and to determine the moving distance of the closed storage container 130. The first preset duration can be set according to actual needs, and can be any value within a range of 10-60 min, for example.
In some alternative embodiments, the method of obtaining the amount of condensation of the sealed storage container 130 may be varied. For example, in the step S802, in the case that the sealing time of the refrigerator 10 exceeds the first preset time, the condensation sensor may be controlled to start to operate to detect the condensation amount of the sealed storage container 130, so that the condensation amount detected by the condensation sensor may be directly obtained.
In other alternative embodiments, another variation may be made in the method of obtaining the amount of condensation from the sealed storage container 130. For example, in the step S802, in the case that the sealing duration of the refrigerator 10 exceeds the first preset duration, the humidity sensor may be controlled to start to operate to detect the absolute humidity in the sealed storage container 130, so that the condensation amount may be indirectly determined according to the absolute humidity detected by the humidity sensor.
The step S804 may include: and judging whether the condensation amount exceeds a preset condensation amount threshold value, if so, acquiring a target distance between the sealed storage container 130 and the air duct assembly 120, and controlling the sealed storage container 130 to move according to the target distance. The dew condensation threshold can be set according to actual needs, and can be any value within the range of 0-10 ml, for example. In this embodiment, the dew amount threshold may be 0. In the case where the amount of condensation exceeds the preset threshold amount of condensation, indicating that condensation has occurred on the inner wall of the hermetic container 130, it may be determined that the hermetic container 130 needs to be moved relative to the air duct assembly 120 to prevent the condensation problem from being worsened.
The step of obtaining the target distance between the sealed storage container 130 and the air duct assembly 120 may include: the size of dew condensed on the surface of the closed storage container 130 is obtained, and the target distance is determined according to the size of dew condensed on the surface of the closed storage container 130. The size of the dew condensed on the surface of the hermetic container 130 includes the diameter of the dew condensed on the surface of the hermetic container 130. That is, the size of the dew may be characterized by the diameter of the dew condensed on the surface of the closed storage container 130. The dew condensed on the surface of the hermetic container 130 may be at least one, and the average value, the maximum value, and/or the minimum value of the diameters of all dew may be calculated. When the diameter of the dew condensed on the surface of the hermetic container 130 is obtained, the diameter of the dew condensed on the surface of the hermetic container 130 may have a value of the maximum value of the diameters of all the dew.
Taking the maximum value of the diameters of all the dewdrops as the diameter value of the dewdrops condensed on the surface of the closed storing container 130, and determining the target interval according to the value, the refrigerator 10 of the embodiment can play a good role in suppressing the dew deterioration problem.
The step of determining the target interval according to the size of dew condensed on the surface of the hermetic container 130 may include: acquiring a preset diameter range, judging whether the diameter of the condensed dew on the surface of the closed storage container 130 is within the diameter range, if so, acquiring an initial distance between the closed storage container 130 and the air duct assembly 120, and determining a target distance according to the diameter and the initial distance of the condensed dew on the surface of the closed storage container 130. The preset diameter range may be a numerical range greater than a preset first diameter threshold and smaller than a preset second diameter threshold. The requirement of the moisture condensation in the national standard test is that no bead or flowing water condensation with a diameter larger than 2mm exists on the inner wall of the container in the storage chamber 111, which is in contact with the test sample, so that the second diameter threshold value can be set to be 2.0mm, and the preset first diameter threshold value can be any value within the range of 0-2 mm, for example, 1 mm.
Wherein the step of determining the target interval according to the diameter and the initial interval of the condensed dew on the surface of the closed storage container 130 may include: according to the formula y ═ y0+ kd calculates the target spacing, where y is the target spacing, y0The initial distance d is the diameter of condensed dew on the surface of the sealed container 130, and k is a predetermined constant. The initial distance between the sealed storage container 130 and the air duct assembly 120 may refer to a distance between the sealed storage container 130 and the air duct assembly 120 when the target distance is obtained, that is, an actual distance between the sealed storage container 130 and the air duct assembly 120 before the movement of the sealed storage container 130 is controlled. In this embodiment, k may be set according to the movable range of the hermetic container 130. In this embodiment, the movable range of the sealed storage container 130 may be any value within a range of 40 to 60mm, and k may be any value within a range of 10 to 30, for example, 20.
