[0002] Refrigeration is a method of storing food or medicine at a certain ambient temperature to extend their shelf life. This is primarily achieved by maintaining low temperatures. Refrigerator cabinets are a common type of refrigeration equipment in the field.

[0003] Refrigerator cabinets are often used in the medical field, such as hospitals, to facilitate the refrigeration and use of medicines by medical staff. Since medical staff use the cabinets frequently within a specific time period, in order to facilitate use, the lock control module is often controlled to be in an unlocked state so that medical staff can freely open or close the cabinet door. At this time, it is difficult to achieve precise control of the fan using the above control method, that is, it is difficult to control the fan according to the actual door opening situation, which can easily lead to temperature loss inside the cabinet and energy waste.

[0055] Example 1

[0056] This embodiment provides a method for controlling a fan of a refrigerator. Figures 6 to 8 As shown, the refrigerator includes a cabinet body 100 and a cabinet door 200. The cabinet body 100 has a storage cavity and also includes a detection module, a lock control module 700 and a fan 300. The fan 300 is arranged on the cabinet body 100 and is used to drive the gas flow in the storage cavity. The lock control module 700 is arranged in the cabinet body 100 and is used to detect the unlocking signal of the cabinet door 200. The detection module is arranged on a side of the cabinet body 100 close to the cabinet door 200 and is used to detect the position information of the cabinet door 200, such as Figure 1 As shown, the fan control method of the refrigerated cabinet includes:

[0057] Step S200, when receiving the unlocking signal from the lock control module 700, obtaining the detection signal generated by the detection module;

[0058] Step S400 , controlling the fan 300 to be turned on or off according to the detection signal.

[0059] Specifically, the refrigerator's cabinet body 100 is hingedly connected to a door 200. A semi-enclosed storage chamber is located within the cabinet body 100, which is used to store medicines or other items requiring refrigeration. The door 200 seals the semi-enclosed storage chamber to ensure the refrigerator's ability to keep medicines and other items cool. Furthermore, the refrigerator's fan 300 is effectively controlled by a detection module, a lock control module, and a control module 600.

[0060] After the control module 600 receives the unlocking signal from the lock control module 700, the control module 600 obtains the detection signal generated by the detection module, and the control module 600 further controls the opening and closing of the fan 300 according to the received detection signal. Among them, the lock control module 700 includes an electronic lock, and the control module 600 includes a controller. When the controller receives the opening signal of the electronic lock, it indicates that the cabinet is in an unlocked state at this time, and the medical staff can quickly open or close the cabinet door according to needs. The detection module is set on the side of the cabinet facing the cabinet door, and the controller obtains the detection signal generated by the detection module. The change in the detection signal shows that the cabinet door is in an open or closed state at this time, and then the controller further controls the opening and closing of the fan 300 according to the detection signal. The use of a method for controlling the fan 300 of a refrigerator provided by the present application solves the problem in the prior art that the refrigerator cannot accurately control the fan when the lock control module is in an open state during use.

[0061] Furthermore, if Figure 2 As shown, controlling the fan 300 to be turned on or off according to the detection signal includes:

[0062] Step S420, when the detection signal is greater than the threshold, the fan 300 is controlled to be turned off;

[0063] Step S440: When the detection signal is less than or equal to the threshold, the fan 300 is controlled to be turned on.

[0064] Specifically, the detection module includes an inductive sensor, which utilizes the principle of electromagnetic induction to convert the measured non-electrical quantity into a change in the self-inductance or mutual inductance of the coil, which is then converted by the measurement circuit into a change in voltage or current for output. In the present application, when the lock control module 700 is unlocked, the inductive sensor is used to detect the opening and closing information of the cabinet door 200. When the inductive sensor detects the movement of a metal object, a damping change occurs within the inductive sensor, which in turn causes a change in the internal output level. As the damping increases, the internal output level signal decreases. It should be noted that the threshold is the level signal value output by the inductive sensor when the cabinet door 200 is closed. By comparing the detected level signal with the threshold, the opening and closing state of the cabinet door 200 is further controlled. In addition, the threshold can also be set to the level signal value output by the inductive sensor when the cabinet door 200 is in a certain position. The opening degree of the cabinet door 200 can then be determined by comparing the detected level signal with the set threshold.

[0065] like Figure 7 and Figure 8As shown, an inductive sensor is installed on the cabinet body 100, and a corresponding metal sheet is installed on the cabinet door 200. When the cabinet door 200 rotates toward the cabinet body 100, the damping inside the inductive sensor gradually increases, and the level signal output by the inductive sensor gradually decreases. When the cabinet door 200 rotates away from the cabinet body 100, the damping inside the inductive sensor gradually decreases, and the level signal output by the inductive sensor gradually increases.

[0066] The controller controls the operating state of the fan 300 by comparing the detection signal with a threshold. The control module 600 includes a storage unit in which the threshold is stored. Therefore, when the controller detects that the detection signal is greater than the threshold, it indicates that the cabinet door 200 is open, and the fan 300 is controlled to be turned off to prevent the loss of cooling energy within the cabinet 100. When the controller detects that the detection signal is less than or equal to the threshold, it indicates that the cabinet door 200 is closed, and the fan 300 is controlled to be turned on to ensure the normal operation of the refrigerator.

[0067] In addition, when the controller does not receive the detection signal within the set time, it means that the cabinet door 200 has not been opened, so the controller controls the lock control module 700 to lock.

[0068] Furthermore, if Figure 8 As shown, a sensing sheet is provided at the bottom of the cabinet door 200, and the detection module includes a sensing area, such as Figure 3 As shown, obtaining the detection signal generated by the detection module includes:

[0069] Step S2002, when the sensing sheet enters the sensing area, a detection signal is obtained;

[0070] Step S3002, detecting a real-time signal value of a detection signal;

[0071] Correspondingly, according to the real-time signal value of the detection signal, controlling the fan to be turned on or off includes:

[0072] Step S4202: When the real-time signal value is greater than the threshold, the fan 300 is controlled to be turned off;

[0073] Step S4402: When the real-time signal value is less than the threshold, the fan 300 is controlled to be turned on.

[0074] Specifically, if Figure 7 and Figure 8As shown, a sensor sheet is provided at the bottom of the cabinet door 200. The sensor sheet is configured in conjunction with the detection module and is used to detect the position of the cabinet door 200 relative to the cabinet body 100. The sensor sheet is a metal sensor sheet. In addition, the sensor sheet can also be made of other materials, provided that the detection module and the sensor sheet generate a sensing signal. The detection module is provided with a certain sensing area. When the cabinet door 200 rotates, when the cabinet door 200 drives the metal sheet on the cabinet door 200 gradually into the sensing area, the detection module senses and generates a detection signal. The detection module uploads the generated real-time detection signal to the control module 600.

[0075] The control module 600 compares the acquired real-time signal value with the set threshold value. When the real-time signal value is greater than the threshold value, it indicates that the cabinet door 200 is in an open state, and the control module 600 controls the fan 300 to be closed to prevent a large amount of cold loss in the cabinet body 100; when the real-time signal value is less than the threshold value, it indicates that the cabinet door 200 is in a closed state or a small opening state, so the fan 300 is controlled to be open to ensure the normal operation of the refrigerator.

[0076] In a specific embodiment, the refrigerator further includes an angle sensor. One end of the door 200 is connected to the cabinet body 100 through a shaft. The angle sensor is arranged on the shaft to collect the angle value of the shaft rotation. When the detection signal is less than or equal to the threshold, Figure 4 As shown, controlling the fan 300 to open also includes:

[0077] Step S620: When the detection signal is less than or equal to the threshold, obtain the current angle value of the angle sensor;

[0078] Step S640: When the current angle value satisfies the preset angle range, the fan 300 is controlled to turn on.

[0079] Specifically, the angle sensor is electrically connected to the controller. The angle sensor is used to further verify the open / closed state of the cabinet door to ensure detection accuracy. When the detection signal is greater than a threshold, it indicates that the cabinet door 200 is open or that there is interfering metal within the sensing area of ​​the detection module. To further control the operating state of the blower, the control module 600 obtains the current angle value of the angle sensor. When it is 0°, it indicates that the cabinet door 200 is closed, and the detection signal at this time is a signal generated by the interfering metal. When the current angle value falls within a preset angle range, it indicates that the cabinet door 200 is open and the opening of the cabinet door 200 is small, so the control module 600 controls the blower 300 to open. When the current angle value exceeds the maximum value of the preset angle range, it indicates that the cabinet door 200 is open and the opening of the cabinet door 200 is relatively large within the detection area, so the blower 300 is controlled to close. The addition of an angle sensor to the detection module eliminates interference from other metal objects on the detection module 600, further achieving relatively accurate control of the blower 300.

[0080] The metal proximity detection module detects that the door 200 is within the detection area when the rotation angle value of the door 200 meets the preset range, further verifying that the detection signal value is generated by the sensor on the door 200. This prevents the detection module from detecting other metals approaching, thereby improving the accuracy of fan control.

[0081] The control module 600 obtains the lock control signal of the lock control module 700. When the lock control signal is an unlock signal, the position of the cabinet door 200 is detected by the detection module. When the control module 600 detects that the detection signal is less than or equal to the threshold, the control module 600 obtains the current angle value of the angle sensor. When the control module 600 detects that the currently obtained angle value is less than or equal to a value within a preset range, it means that the opening of the cabinet door 200 is small, so the fan 300 is controlled to be turned on to ensure the normal operation of the refrigerator; when the current angle value is greater than a value within the preset range, it means that the opening of the cabinet door 200 is large, so the fan 300 is controlled to be turned off to prevent the cabinet body 100 from losing too much cold. Among them, the preset range value is stored in the storage unit of the control module 600. The preset range value is related to the angle value corresponding to the threshold. Specifically, when the threshold is I j When the maximum value of the real-time signal normally output by the first detection module 400 is I max ;I j =I max / (2~3).

[0082] When the detection signal value is equal to the threshold, the angle value generated by the angle sensor at this time is obtained, the angle value is stored, and 0° to the angle measurement value is used as a pre-stored angle range value.

[0083] In a specific embodiment, the detection module includes a first detection module 400 and a second detection module 500. The first detection module 400 and the second detection module 500 are respectively arranged at the bottom or the top of the cabinet 100. The second detection module 500 is close to the side of the cabinet door 200 rotation axis, and the first detection module 400 is away from the side of the cabinet door 200 rotation axis. Figure 5 As shown, the fan control method of the refrigerated cabinet further includes:

[0084] Step S602: Acquire a first detection signal generated by the first detection module 400 and a second detection signal generated by the second detection module 500;

[0085] Step S612: When the first detection signal is greater than the threshold, the fan 300 is controlled to be turned off;

[0086] Step S622: When the second detection signal and the first detection signal are both less than or equal to the threshold, the current angle value collected by the angle sensor is obtained.

[0087] Specifically, if Figure 9 The real-time signal diagram of the first detection module 400 and the second detection module 500 during the door opening process is provided, where the horizontal axis in the diagram represents time t, the vertical axis in the diagram represents the real-time signal value during the opening process of the cabinet door 200, the solid line in the diagram represents the real-time signal sent by the first detection module 400, and the dotted line in the diagram represents the real-time signal sent by the second detection module 500. Figure 10 The following figure shows the real-time signals of the first detection module 400 and the second detection module 500 during the door closing process. The horizontal axis of the figure represents time t, and the vertical axis represents the real-time signal value during the closing process of the cabinet door 200. The solid line in the figure represents the real-time signal sent by the first detection module 400, and the dotted line in the figure represents the real-time signal sent by the second detection module 500. It can be seen from the figure that the rate of change of the second detection module 500 is greater than the rate of change of the first detection module 400.

[0088] The control module 600 obtains the detection signals of the first detection module 400 and the second detection module 500 and compares them with a threshold. When the threshold is set to the level signal value output by the sensor, when the first detection signal is greater than the threshold, it indicates that the cabinet door 200 is in a relatively large open state. At this time, the control module 600 controls the fan 300 to close. It should be noted that the large open state here refers to the relatively large open state when the cabinet door 200 is within the detection range of the detection module 600. When the detection signals of the first detection module 400 and the second detection module 500 are both less than or equal to the threshold, the control module 600 obtains the current angle value signal collected by the angle sensor. When the current angle value is less than or equal to the value within the preset angle range, it indicates that the cabinet door 200 is in a relatively small open state or closed state. Therefore, the fan 300 is controlled to open to ensure the normal operation of the refrigerator. Among them, the fan 300 is controlled to open by satisfying the conditions of two sensors at the same time. Since the second detection module 500 is closer to the rotating shaft, the level of the second detection module 500 changes faster, and the level of the first detection module 400 changes slower. The first detection module 400 and the second detection module 500 verify and judge the position of the cabinet door 200, and then control the fan 300 to open. When the lock control module 600 detects that the door is closed, it is locked.

[0089] In a specific embodiment, the method further comprises:

[0090] Get the angle value collected by the angle sensor in real time;

[0091] When the first detection signal is equal to the threshold, obtaining the adjacent point angle value collected by the angle sensor;

[0092] The angle range that is less than or equal to the adjacent point angle value is pre-stored as the preset angle range.

[0093] Specifically, during the process of opening the cabinet door, the controller obtains the angle value collected by the angle sensor in real time and stores it in the storage unit; when the first detection signal value is equal to the threshold, the immediate angle value of the angle sensor at this time is obtained, the immediate angle value is stored, and 0° to the immediate angle value is used as the pre-stored angle range value.

[0094] Example 2

[0095] This application provides a refrigerator, such as Figures 6 to 8 As shown, the refrigerator includes a cabinet body 100 and a cabinet door 200, wherein the cabinet body 100 and the cabinet door 200 are rotatably connected. The cabinet body 100 has a storage cavity and is characterized in that it further includes:

[0096] The lock control module 700 is provided between the cabinet body 100 and the cabinet door 200 and is used to detect an unlocking signal of the cabinet door 200;

[0097] A detection module is provided on a side of the cabinet body 100 close to the cabinet door 200 and is used to detect position information of the cabinet door 200;

[0098] The fan 300 is provided on the cabinet 100 and is used to drive the gas flow in the storage cavity;

[0100] Specifically, the refrigerator's cabinet body 100 is hingedly connected to a door 200. A semi-enclosed storage chamber is located within the cabinet body 100, which is used to store medicines or other items requiring refrigeration. The door 200 seals the semi-enclosed storage chamber to ensure the refrigerator's ability to keep medicines and other items cool. Furthermore, the refrigerator's fan 300 is effectively controlled by a detection module, a lock control module, and a control module 600.

[0101] During use, after the control module 600 receives the unlock signal from the lock control module 700, it obtains the detection signal generated by the detection module. Based on the received detection signal, the control module 600 further controls the opening and closing of the fan 300. The lock control module 700 includes an electronic lock, and the control module 600 includes a controller. When the controller receives the unlock signal from the electronic lock, it obtains the detection signal generated by the detection module. Based on the detection signal, the controller further controls the opening and closing of the fan 300. The fan control method for a refrigerator provided in this application solves the problem of internal temperature loss and energy waste during use of refrigerators in the prior art.
