Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and in particular to an ice-making device, refrigeration equipment and an automatic ice-making method of the ice-making device. Background Art

[0002] With the development of science and technology and the continuous improvement of people's living standards, refrigerators have become a necessity in people's lives. Refrigerators use refrigeration to maintain a low temperature inside, which can not only preserve items, but also make ice by setting up a simple ice maker, greatly facilitating users' needs for ice.

[0003] However, the existing ice-making devices need to use at least two kinds of hardware to detect the ice-making detection of the ice-making assembly and the full ice detection of the ice storage box respectively. These hardware occupy the volume of the ice-making device, resulting in a bloated ice-making device. Especially in a refrigerator equipped with an ice-making device, the use space of the refrigerator is particularly important. The bloated ice-making device is not popular with consumers. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the related art.

By rotating the ice-making grid to avoid the second detection signal of the transmitter, the ice-making device only needs to use a set of sensor hardware to realize ice-making detection of the ice-making component and full ice detection of the ice storage box, thereby reducing the hardware usage of the ice-making device, effectively increasing the space utilization rate, avoiding the bloatedness of the ice-making device, and reducing the risk of failure and manufacturing cost.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0050] According to an embodiment of the present invention, an ice making device is shown in FIG. Figure 1 , comprising: an ice-making assembly 100, a sensor 300 and an ice storage box 200. The ice-making assembly 100 comprises a mounting frame 110 and an ice-making grid 120, the ice-making grid 120 is rotatably connected to the mounting frame 110, and the ice-making grid 120 has an ice-making position, an ice-removing position and an avoidance position; the ice storage box 200 has a receiving chamber 201 formed inside for storing ice cubes made by the ice-making assembly 100. The sensor 300 comprises a transmitter 310, a first receiver 320 and a second receiver 330; the transmitter 310 is adapted to transmit a first detection signal toward the ice-making grid 120, or, when the ice-making grid 120 is in the avoidance position, the transmitter 310 is adapted to transmit a second detection signal toward the ice storage box 200; the first receiver 320 is adapted to receive a first reflection signal; the second receiver 330 is adapted to receive a second reflection signal; wherein the first reflection signal is a reflection signal formed after the first detection signal passes through the ice-making grid 120, and the second reflection signal is a reflection signal formed after the second detection signal passes through the ice storage box 200.

[0051] According to the ice-making device of the embodiment of the present invention, the ice-making grid 120 is located in the ice-making position, and the transmitter 310 can send a first detection signal toward the ice-making grid 120. By rotating the ice-making grid 120 to the avoidance position, the ice-making grid 120 can avoid the second detection signal of the transmitter 310. The ice-making device only needs to use a set of sensor hardware to realize ice-making detection of the ice-making assembly 100 and full ice detection of the ice storage box 200, thereby reducing the hardware usage of the ice-making device, effectively increasing space utilization, avoiding bloating of the ice-making device, reducing the risk of failure, and reducing the manufacturing cost of the ice-making device.

[0052] It is understandable that the ice making tray 120 can be switched between the ice making position, the ice removing position and the avoidance position (the ice making position, the ice removing position and the avoidance position can be specifically referred to in Figure 1 , Figure 2 and Figure 3 ). The ice-making grid 120 can perform ice-making operations at the ice-making position and wait for the ice cubes to be formed. After ice making is completed, the ice-making grid 120 rotates to the ice-removing position, so that the ice cubes can be quickly separated from the ice-making grid 120. The ice-making grid 120 can make ice normally in the ice-making position, and the transmitter 310 transmits a first detection signal toward the ice-making grid 120. The ice-making device can determine whether ice making is completed based on the signal strength and change rate of the first reflected signal reflected by the ice-making grid 120. After the ice-removing is completed, the ice-making grid 120 rotates to the avoidance position, and the transmitter 310 can transmit a second detection signal toward the ice storage box 200 at the same angle. The ice-making device can determine whether the ice storage box 200 is full of ice cubes based on the signal strength and change rate of the second reflected signal reflected by the ice storage box 200. The reflection principle can be specifically referred to. Figure 4 .

[0053] It is understandable that when it is detected that the ice cubes in the ice storage box 200 are full, the next round of ice making operation of the ice making device is stopped. If the ice cubes in the ice storage box 200 are not full, the ice making operation is continued.

[0054] The present invention does not specifically limit the driving method of the ice making tray 110. The ice making assembly 100 can drive the ice making tray 120 to rotate by a motor or by other methods.

[0055] It should be noted that the first detection signal and the second detection signal may be signals of different frequencies or signals of different strengths, or may be signals of the same frequency and the same strength, and the present invention does not impose any specific limitation on this.

[0056] It can be understood that the sensor 300 can be a distance sensor 300, which measures the distance by using changes in physical quantities such as sound waves, light waves or electromagnetic waves. The sound wave distance sensor 300 determines the distance by emitting sound waves and measuring the signal strength or time of the sound waves reflected back, such as an ultrasonic distance sensor 300, a sonar distance sensor 300, etc.; the light wave distance sensor 300 determines the distance by emitting light waves and measuring the strength or time of the light waves returning, such as an infrared distance sensor 300, a laser distance sensor 300, etc.; the electromagnetic wave distance sensor 300 determines the distance by emitting electromagnetic waves and measuring the strength or time of the electromagnetic waves returning, such as a radar distance sensor 300, etc.

[0057] Since water and ice have different absorption and transmission properties for the first detection signal, the strength of the reflected first reflection signal is also different. The first receiver 320 can determine whether ice making is completed based on the strength and change rate of the first reflection signal.

[0058] It is understandable that the installation positions of the transmitter 310, the first receiver 320 and the second receiver 330 satisfy the law of reflection. The installation positions of the transmitter 310, the first receiver 320 and the second receiver 330 can be the same or different. The following examples are respectively given for one case where the installation positions are the same and one case where the installation positions are different:

[0059] In one embodiment, please refer to Figure 1, the mounting frame 110 is at least partially located above the ice making grid 120, the transmitter 310, the first receiver 320 and the second receiver 330 of the sensor 300 are all arranged at a position where the mounting frame 110 is located above the ice making grid 120, the transmitter 310 transmits a first detection signal toward the ice making grid 120 at an inclined preset angle, and transmits a second detection signal toward the ice storage box 200 at the same angle, the first receiver 320 is set corresponding to the reflection angle of the first detection signal, and the second receiver 330 is set corresponding to the reflection angle of the second detection signal.

[0060] In one embodiment, the transmitter 310, the first receiver 320, and the second receiver 330 of the sensor 300 are arranged at the same position. The transmitter 310 transmits the first detection signal and the second detection signal vertically downward. In the ice making position, the ice making grid 120 reflects the first detection signal as a first reflection signal, which is vertically upward toward the first receiver 320. In the avoidance position, the ice storage box 200 reflects the second detection signal as a second reflection signal, which is vertically upward toward the second receiver 330. It can be understood that the transmitter 310, the first receiver 320, and the second receiver 330 are arranged at the same position, which can reduce the complexity of wiring, reduce unnecessary occupied space, and also help to simplify the installation and debugging process of the sensor 300, save installation time, and improve the reliability of the sensor 300.

[0061] According to one embodiment of the present invention, in the ice making position, please refer to Figure 1 , the opening 121 of the ice tray 120 faces upward; in the ice-removing position, please refer to Figure 2 , the opening 121 of the ice making tray 120 faces downward; during the process of the ice making tray 120 rotating from the ice removing position toward the ice making position, the ice making tray 120 passes through the avoidance position, please refer to Figure 3 .

[0062] It is understandable that, in the ice making position, which is also the initial position of the ice making grid 120, the opening 121 of the ice making grid 120 faces upward, and the ice making grid 120 can perform ice making operations at the ice making position and wait for ice cubes to be formed. After ice making is completed, the ice making grid 120 rotates to the ice removing position, and the opening 121 of the ice making grid 120 faces downward, so that ice cubes can quickly escape from the ice making grid 120. After ice removing is completed, during the process of the ice making grid 120 rotating from the ice removing position to the ice making position, the ice making grid 120 passes through the avoidance position, and the ice making grid 120 rotates to the avoidance position, and the transmitter 310 can transmit the second detection signal toward the ice storage box 200 at the same angle.

[0063] The transmitter 310 can transmit the first detection signal and the second detection signal toward the ice storage box 200 at the same angle, which can simplify the detection steps. There is no need to adjust the angle or position of the transmitter 310, which can simplify the manufacturing and debugging process of the ice making device. It only needs to switch the target object for detection. Using the same angle to transmit signals can also make it easier to compare the signal strength and change rate, so as to determine whether ice making is completed and the amount of ice storage box 200.

[0064] According to one embodiment of the present invention, the transmitter 310 is suitable for detecting the height of ice cubes at the outer edge of the ice storage box 200. It is understandable that as the number of ice making operations increases, the ice cubes stored in the ice storage box 200 are prone to partial stacking in the middle. In other words, the ice cubes in the ice storage box 200 are stacked with the middle high and the outer edge low. By detecting the height of ice cubes at the outer edge of the ice storage box 200, it is determined whether the ice storage box 200 is full of ice, which can ensure the accuracy of the ice making device's judgment on whether the ice storage box 200 is full of ice.

[0065] According to one embodiment of the present invention, the ice storage box 200 is provided with a vibrator (not shown in the figure), which is suitable for vibrating the ice storage box 200 so that the ice cubes in the ice storage box 200 are evenly distributed in the accommodating cavity 201. The ice cubes are vibrated evenly by the vibration of the vibrator, thereby ensuring the accuracy of the ice making device in judging whether the ice is full. It should be noted that the "evenly" here refers to the fact that the gaps between the ice cubes can be minimized by the vibrator, thereby reducing the detection error.

[0066] According to an embodiment of the present invention, the sensor 300 is disposed on the mounting frame 110, the ice-making assembly 100 is located above the ice storage box 200, and the angle between the incident direction of the transmitter 310 and the horizontal plane is 45 degrees to 90 degrees.

[0067] It is understandable that when the angle between the incident direction of the transmitter 310 and the horizontal plane is 45 degrees, the detection range of the sensor 300 can be maximized, and the sensor 300 can receive a stronger reflected signal. When the incident angle is 45 degrees, the target surface reflects the detection signal (including the first detection signal and the second detection signal) of the transmitter 310 more directly, and the reflected signal will be stronger, thereby improving the sensitivity and detection capability of the sensor 300. In addition, when the angle between the incident direction of the transmitter 310 and the horizontal plane is 45 degrees, the ice tray 120 is more likely to avoid the second detection signal of the transmitter 310, and the ice tray 120 can also rotate 45 degrees so that the bottom of the ice tray 120 is parallel to the incident signal to avoid the detection signal of the transmitter 310.

[0068] When the angle between the incident direction of the transmitter 310 and the horizontal plane is 90 degrees, the transmitter 310, the first receiver 320 and the second receiver 330 of the sensor 300 are arranged at the same position, which will not be described in detail here.

[0069] In one embodiment, the ice making tray 120 can be rotated 180 degrees to switch the ice making position to the ice removing position, and can be rotated 90 degrees from the ice removing position to the avoidance position. The transmitter 310 can directly detect whether the ice storage box 200 is full of ice cubes.

[0070] The refrigeration device according to the embodiment of the present invention comprises: a body, a door body and the above-mentioned ice-making device. A refrigeration compartment and an opening 121 connected to the refrigeration compartment are formed inside the body; the door body can be opened and closed and connected to the opening 121; and the ice-making device is arranged in the refrigeration compartment.

[0071] It should be noted that, since the refrigeration equipment includes the above-mentioned ice-making device, it has all the technical effects of the above-mentioned ice-making device, which will not be repeated here.

[0072] It should be noted that the refrigeration equipment can be a refrigerator, an ice maker, a cold drink machine, etc.

[0073] According to one embodiment of the present invention, the transmitter 310 is suitable for detecting ice cubes in the ice making tray 120 near the door. It is understandable that the water near the door freezes last, and as long as the water in the outermost and edgemost ice tray is detected to be frozen, combined with the judgment of the sensor 300, it can be said that this round of ice making has been completed, and the next step of defrosting can be carried out.

[0074] According to one embodiment of the present invention, the ice making assembly 100 includes a frame, and the mounting frame 110 is rotatably connected to the frame, and is suitable for rotating the ice making tray 120 from a side close to the door body to a side away from the door body. It can be understood that the water near the door body freezes last, and the ice making tray 120 is rotated from a side close to the door body to a side away from the door body at a set time, thereby increasing the speed of ice cube formation.

[0075] According to the automatic ice-making method of the ice-making device of the embodiment of the present invention, the ice-making device includes an ice-making assembly 100 and an ice storage box 200, the ice-making assembly 100 includes a mounting frame 110 and an ice-making grid 120 rotatably connected to the mounting frame 110, and the ice storage box 200 is used to store ice cubes made by the ice-making grid 120, including:

[0076] Step 10: Determine that the ice making tray 120 is in the ice making process, and control the transmitter 310 to transmit a first detection signal to the ice making tray 120;

[0077] Step 20: based on the first reflection signal received by the first receiver 320 meeting the first preset condition, determining that the ice making tray 120 has completed ice making, so as to control the ice making tray 120 to defrost, wherein the first reflection signal is a reflection signal formed after the first detection signal passes through the ice making tray 120;

[0078] Step 30: confirming that the ice making tray 120 has finished de-icing, controlling the ice making tray 120 to rotate from the de-icing position toward the ice making position, and when the ice making tray 120 rotates to the avoidance position of the transmitter 310, controlling the transmitter 310 to transmit a second detection signal to the ice storage box 200;

[0079] Step 40: Based on the second reflection signal received by the second receiver 330 satisfying the second preset condition, it is determined that the ice storage box 200 is full of ice to control the ice making tray 120 to stop making ice, wherein the second reflection signal is a reflection signal formed after the second detection signal passes through the ice storage box 200.

[0080] It should be noted that the first preset condition can be to determine whether the intensity of the first reflected signal is greater than the first preset intensity, or whether the rate of change of the first reflected signal changes. Among them, when the intensity of the first reflected signal is greater than the first preset intensity, it can be determined that the ice making of the ice making grid 120 has been completed. The intensity of the first reflected signal no longer changes and can also be used to determine that the ice making is completed. Similarly, the second preset condition can be to determine whether the intensity of the second reflected signal is greater than the second preset intensity, or whether the transmission distance of the second reflected signal is a preset distance. Among them, when the intensity of the second reflected signal is greater than the second preset intensity, it can be determined that the ice storage box 200 is full of ice cubes. The transmission distance of the second reflected signal is less than the preset distance and can also be used to determine that the ice storage box 200 is full of ice cubes. Of course, the first preset condition and the second preset condition can also be other, as long as it can be determined that the ice making of the ice making grid 120 is completed and the ice storage box 200 is full of ice cubes.

[0081] It is understandable that during the ice-making process, the transmitter 310 may transmit a first detection signal at regular intervals, and the first receiver 320 may determine whether the ice-making is completed based on the change rate of the reflected first detection signal.

[0082] According to one embodiment of the present invention, determining that the ice making tray 120 is in the ice making process, and controlling the transmitter 310 to transmit a first detection signal to the ice making tray 120, includes:

[0083] It is determined that the ice making time of the ice making tray 120 reaches the set time, and the transmitter 310 is controlled to transmit a first detection signal to the ice making tray 120 .

[0084] It is understandable that the ice-making device can also transmit the first detection signal according to the ice-making time, which can avoid unnecessary signal transmission, save energy and resource utilization, and increase the service life of the sensor 300. And by ensuring that the ice-making time reaches the set time, unnecessary extension of the ice-making time can be avoided, ensuring that the ice-making process of the ice-making grid 120 is completed within an appropriate time, thereby ensuring the quality and effect of ice-making.
