Detailed Description
Fig. 1 is a schematic structural block diagram of a refrigerator according to one embodiment of the present invention. The refrigerator may generally include: at least one detection assembly 100 and a volume calculation device 200. Wherein the sensing assembly 100 is disposed in the storage compartment 400 of the refrigerator for emitting an optical signal and sensing the optical signal. These optical signals include visible light and infrared light. Specifically, each detection assembly 100 comprises at least: a visible light source 110, an infrared light source 120, and a light-sensing device 130. The visible light source 110 is configured to emit visible light into the storage compartment 400. The infrared light source 120 is configured to emit infrared light into the storage compartment 400. The light sensing device 130 is configured to detect the intensity of visible light and the intensity of infrared light at the location of the detection assembly 100. The number of detection assemblies 100 may be determined according to the volume and structure of the storage compartment 400. After a large number of tests of the inventor, the following results are obtained: for storage compartments 400 of less than or equal to 30L, one detection assembly 100 may be utilized. For a storage compartment 400 with a layered structure larger than 30L, a plurality of detection assemblies 100 need to be arranged.
With the change of the use size of the use volume of the storage chamber 400, the reflection and shielding conditions of the visible light and the infrared light in the storage chamber 400 are changed, the transmission characteristics of the visible light and the infrared light are different, and the rules that the intensity of the visible light and the intensity of the infrared light are changed along with the change of the use volume are summarized and tested by the inventor, so that the refrigerator volume detection is realized by utilizing the optical principle.
A volume calculating device 200 electrically connected to the at least one detecting assembly 100, respectively, and configured to: the intensity of the visible light and the intensity of the infrared light are acquired, and the usage volume of the storage compartment 400 is calculated according to the intensity of the visible light and the intensity of the infrared light.
Fig. 2 and fig. 3 respectively show a schematic diagram of arranging a plurality of detection assemblies 100 and one detection assembly 100 in a storage compartment 400 of a refrigerator, wherein when a plurality of detection assemblies 100 are arranged, the plurality of detection assemblies 100 are distributed inside a peripheral wall of the storage compartment 400, and an included angle between a connecting line of central points of any two detection assemblies 100 arranged on the same plane of the peripheral wall and other planes intersecting the plane in the peripheral wall is not 0 degree or 90 degrees; the included angle between the connecting line of the central points of any two detection assemblies 100 arranged on different planes of the peripheral wall and the horizontal plane or the vertical plane is not 0 degree or 90 degrees.
According to the above requirement, if at least two of the plurality of detection assemblies 100 are disposed on the top wall or the bottom wall, and the included angle between the line connecting the center points of any two of the detection assemblies 100 disposed on the top wall or the bottom wall and the vertical plane where the side wall is located is not 0 degree or 90 degrees. If at least two of the plurality of inspection assemblies 100 are disposed on the side walls, and the inspection assemblies 100 disposed on the side walls are spaced apart in the vertical direction and do not lie in a plane parallel to the rear wall. If a rack is disposed in the storage compartment 400 and parallel to the top wall, so as to divide the storage compartment 400 into a plurality of storage compartments, a detection assembly 100 needs to be disposed in each storage compartment.
Fig. 2 shows a case where three detection members 100 are arranged on three sides in the side wall, respectively. According to the position relationship of the three detection assemblies 100 in the vertical direction, the three detection assemblies are respectively called a first detection assembly 101, a second detection assembly 102 and a third detection assembly 102.
One specific algorithm for using volume detection with the configuration shown in fig. 2 is:
calculating a used volume of a storage compartment of a detection target includes: estimating the used volume of the storage interval of the detection target according to the formula 1:
equation 1: vn' is SnA x kn,
in formula 1, n is a serial number of the detection assembly 100 in the detection target storage space, Vn' is an estimated value corresponding to the nth detection assembly 100, SnA is a visible light intensity value detected by the nth detection assembly 100, and kn is a visible light estimation coefficient of the nth detection assembly 100;
the estimated Vn' is modified according to equation 2:
equation 2: vn ═ Vn' + ∑ SmA × Mmn;
in formula 2, m is a serial number of the detection assembly 100 adjacent to the detection assembly 100 in the storage space of the detection target in the vertical direction, m takes a value of n-1 and/or n +1, SmA is the visible light intensity detected by the mth detection assembly 100, and Mmn is a calculation correction factor of the mth detection assembly 100 for the nth detection assembly 100, which is calculated according to formula 3:
equation 3: mmn ═ (Smp × Jmn)/(SmA × Tmn),
in equation 3, Smp is the infrared light intensity detected by the mth detection module 100, Jmn is the infrared light correction constant for the nth detection module 100 detected by the mth detection module 100, and Tmn is the distance value corresponding to the infrared light intensity detected by the mth detection module 100. kn and Jmn are constants pre-stored in the refrigerator and are statistically derived by pre-experiments.
For the first detecting component 101, the detecting component 100 adjacent to the first detecting component in the vertical direction is the second detecting component 102, and the volume thereof is:
V1＝S1A×k1+S2A×((S2P×J21)/(S2A×T21))。
for the second detection assembly 102, the detection assemblies 100 adjacent to each other in the vertical direction are the first detection assembly 101 and the third detection assembly 102, and the volumes thereof are as follows:
V2＝S2A×k2+S1A×((S1P×J12)/(S1A×T12))+S3A×((S3P×J32)/(S3A×T32))。
for the third inspection assembly 102, the adjacent inspection assembly 100 in the vertical direction is the second inspection assembly 102, and the volume thereof is:
V3＝S3A×k3+S2A×((S2P×J23)/(S3A×T23))。
if the use volumes of the storage compartments in which the first detection assembly 101, the second detection assembly 102 and the third detection assembly 102 are located are required, the V1, the V2 and the V3 can be directly used. If the total using volume of the storage compartment 400 needs to be detected, V1, V2 and V3 can be accumulated.
The above detection principle is that visible light can pass through the glass at equal intervals and irradiate the whole storage chamber 400, while general infrared light cannot pass through the glass at equal intervals.
Only one detection assembly 100 may be arranged when the available volume of the storage compartment 400 is small, for example less than 30L. The detection algorithm is as follows:
the volume used is estimated according to equation 4:
equation 4: v 'is SA × k + SP × J × T/SA, where in formula 4, V' is an estimated value of the usage volume, SA is a visible light intensity value detected by the detection module 100, k is a visible light estimation coefficient of the detection module 100, M is a correction factor, SP is an infrared light intensity value detected by the detection module 100, J is an infrared light correction constant of the detection module 100, and T is a distance value corresponding to the infrared light intensity detected by the detection module 100. k and J are constants stored in the refrigerator in advance, and the numerical values of k and J are determined after the volume of the refrigerator and the position of the detection assembly are determined through preliminary experimental statistics.
The above volume calculating device 200 may be integrally provided with one of the sensing assemblies 100, or may be disposed on a main control panel of the refrigerator.
The refrigerator of the present example may further include: and a control device 300. The control device 300 may control the detection assembly 100 and the volume calculation device 200, or may intelligently control the cooling of the refrigerator according to the calculated usage volume. For example, the control device 300 may be connected to the volume calculation device 200 and the at least one detection assembly 100, respectively, and configured to: a volume calculation trigger signal is acquired and the volume calculation device 200 and the at least one detection assembly 100 are controlled to be turned on. The triggering signal may be a door closing signal of a refrigerator, and generally, food is generally taken and placed by opening a refrigerator door, so the control device 300 may trigger volume detection once after each door closing.
In addition, the control device 300 is further configured to: acquiring the use volume calculated by the volume calculating device 200; and adjusts a cooling state of the refrigerator according to the usage volume and/or outputs the usage volume to a user. For example, after a door closing signal of the refrigerator is acquired, a volume detection device in the storage compartment 400 of the refrigerator is started to detect the use volume of the storage compartment 400; comparing the detected use volume with the use volume before the refrigerator is closed; if the detected usage volume is larger than the usage volume before the door is closed, the cold source driving the storage compartment 400 operates at high power, so that the refrigerator enters a quick cooling mode. So that the temperature of the just-placed food is rapidly reduced. The time to enter the rapid cooling mode may be determined according to the magnitude of the volume change. The control device 300 may also output the usage volume to the user terminal in a wireless manner, and output a food supplement prompting signal to the refrigerator user when the usage volume is less than a preset volume threshold.
The embodiment of the invention also provides a using volume detection method of the refrigerator. Fig. 4 is a schematic view of a usage volume detecting method of a refrigerator according to one embodiment of the present invention, the method including:
step S402, starting the visible light source 110 and the infrared light source 120 in at least one detection assembly 100 arranged inside the storage compartment 400 of the refrigerator to provide visible light and infrared light into the compartment of the refrigerator;
step S404, starting the light sensing device 130 of at least one detection assembly 100 to detect the visible light intensity and the infrared light intensity of the respective positions of the detection assemblies 100;
step S406, calculating the usage volume of the storage compartment 400 according to the intensity of the visible light and the intensity of the infrared light.
A volume calculation trigger signal may also be acquired prior to step S402, the volume calculation trigger signal including any one or more of: timing signal, refrigerator door closing signal, user operation trigger signal.
Also after step S406, the calculated usage volume may be acquired; and adjusts a cooling state of the refrigerator according to the usage volume and/or outputs the usage volume to a user.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
