[0038] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0039] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.
[0040] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.
[0041] With the development of home appliance technology, the degree of intelligence of home appliances such as refrigerators is getting higher and higher. Among them, refrigerators with automatic door opening and closing functions are becoming more and more popular among users. Refrigerators with automatic door opening and closing functions are more convenient to use. However, in the process of automatic door closing, existing refrigerators with automatic door opening and closing functions may cause the risk of pinching the user's fingers, which leads to low safety of the refrigerator and poor user experience.
[0042] Taking into account the above-mentioned problems existing in existing refrigerators, the present application proposes a method that can detect whether a user touches the refrigerator during the automatic closing process of the refrigerator, so as to avoid pinching the user during the automatic closing process, thereby improving the safety of the refrigerator and improving the user experience.
[0043] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0044] first, Figure 1 This is a schematic diagram of the structure of a refrigerator provided in this application. Figure 1 As shown, the refrigerator may include: a control device, a touch sensing device, and a door body. The touch sensing device may include: a control board and a touch panel. The control board may include: a sensing electrode and a control circuit.
[0045] The touch sensing device may be arranged at a first position of the door body. The first position may be a position touched by a user when opening or closing the door. The control board may be connected to the touch panel via a sensing electrode. The control board may be connected to the control device via a control circuit.
[0046] In some embodiments, the control device may be, for example, any existing device with processing functions such as a microcontroller unit (MCU). In some embodiments, the control device may also be referred to as the main controller of the refrigerator. Taking the control device as an MCU as an example, the control device may be the main controller MCU of the refrigerator.
[0047] It should be understood that the touch sensing device can be set at the position on the door body that the user touches when opening and closing the door, so that when the user touches the refrigerator door body to open and close the door, it is more likely that the user touches the sensing device, so that the refrigerator can detect the user touching the refrigerator door body with higher accuracy, thereby further improving the safety of the refrigerator.
[0048] It should be understood that Figure 1 The position of the touch sensing device on the door body shown in is only an exemplary description provided by the present application, and the present application does not limit the position touched when the user opens and closes the door. It should be understood that the above-mentioned door body can be a refrigerator door body of a refrigerator compartment, and / or a refrigerator door body of a freezer compartment, etc., and the present application does not limit this.
[0049] In some embodiments, the sensing electrode may be, for example, a pad on a control board. By using the pad as an induction motor, no additional components are needed to sense whether the user has touched the door, thereby reducing the circuit complexity of the control board.
[0050] For example, Figure 2 This is a schematic diagram of the structure of a control panel provided in this application. Figure 2 As shown, the control board may include a sensing electrode area (sensing area) and a control circuit.
[0051] In some embodiments, the touch panel may be a metal decorative plate on the door body, so that the touch panel has conductivity.
[0052] It should be understood that the present application does not limit whether the refrigerator includes other components. Figure 1 The structure of the refrigerator is merely described by taking some components involved in the present application as an example. Figure 3 This is a schematic diagram of another refrigerator structure provided by this application. Figure 3 As shown, the refrigerator may further include a conductive sponge. The control panel may be disposed in a control panel box. Figure 3 The printed circuit board including the large-area touch pad shown in the figure can be connected to the touch panel (metal sensing decorative plate) through the conductive sponge through the sensing electrode (large-area touch pad).
[0053] The control circuit can be used to sense whether a user touches the touch panel through the sensing electrodes, and when sensing that a user touches the touch panel, output a first instruction indicating that a user touches the touch panel to the control device.
[0054] The above-mentioned control device can be used to control the door body to automatically close in response to an automatic door closing instruction, and control the door body to stop closing when receiving a first instruction.
[0055] That is, the refrigerator can sense whether the user touches the touch panel through the sensing electrode, and output a first instruction indicating that the user touches the touch panel to the control device through the control circuit when sensing that the user touches the touch panel. The refrigerator can control the door to automatically close in response to the automatic door closing instruction through the control device, and control the door to stop closing when receiving the first instruction.
[0056] It should be understood that the present application does not limit how the control device obtains the automatic door closing instruction. For example, the method for the control device to obtain the automatic door closing instruction can refer to any existing refrigerator automatic door opening and closing method, and the present application does not limit this.
[0057] Optionally, the control device may, for example, control the door driving device so that the door driving device drives the door to close automatically, or causes the door driving device to brake the door to stop closing.
[0058] In this embodiment, a touch sensing device is provided at the position on the refrigerator door body that is touched by the user when opening and closing the door, so that the refrigerator can detect whether the user touches the door body based on the touch sensing device. The touch panel in the above touch sensing device can be connected to the sensing electrode on the control board without being connected via a spring, thereby avoiding multiple welding and the problem of consistency differences in different sensing positions, improving the accuracy of sensing, and further improving the reliability and consistency of the refrigerator sensing the human body. The refrigerator can control the door body to stop closing when receiving the first instruction from the control circuit through the control device. By controlling the door body to stop closing when the user touches the touch panel on the refrigerator door body, the possibility of the door body pinching the user due to continued closing is avoided, thereby improving the safety of the refrigerator and further improving the user experience.
[0059] The following is a detailed description of how the control circuit senses whether a user touches the touch panel through the sensing electrodes, and outputs a first instruction for indicating that a user touches the touch panel to the control device when sensing that a user touches the touch panel:
[0060] As a possible implementation, the control circuit can be used to determine that a user touches the touch panel when the capacitance value between the sensing electrode and the user's finger is greater than or equal to a preset capacitance value, and output a first instruction to the control device. The capacitance value between the sensing electrode and the user's finger can be related to the area of the sensing electrode and the thickness of the touch panel.
[0061] Optionally, the capacitance value between the sensing electrode and the user's finger may be, for example, expressed as follows:
[0062]
[0063] The above S can be used to characterize the area of the sensing electrode, ε represents the dielectric constant of the panel, d represents the thickness of the touch panel, and C represents the capacitance value between the sensing electrode and the user's finger.
[0064] Exemplarily, when there is no finger approaching, the capacitance on the sensing electrode is composed of the parasitic capacitance between the electrode and the surrounding ground wire or other signal leads. When a finger approaches or touches the panel (touch panel) above the sensing electrode, the electric field above the sensing electrode plate is enhanced due to the conductivity of the human body, forming a capacitor in parallel with the parasitic capacitance, thereby increasing the total capacitance on the sensing electrode. The sensing detection circuit can determine whether there is a finger touching the refrigerator door by detecting the change in this capacitance.
[0065] Through the above method, the control panel can determine whether a user touches the touch panel based on the capacitance value between the sensing electrode and the user's finger, and when the user touches the touch panel, send a first instruction to the control device, so that the control device can control the door to stop closing based on the first instruction.
[0066] The following is a detailed description of how the control device responds to the automatic door closing instruction to control the door body to automatically close, and controls the door body to stop closing when receiving the first instruction:
[0067] As a possible implementation, the control device may control the door to close automatically in response to an automatic closing instruction, and determine whether the automatic closing of the door reaches a first limit position. When the automatic closing of the door reaches the first limit position, if the first instruction is received, the door is controlled to stop closing. By controlling the door to stop closing, the user is prevented from being pinched. Exemplarily, the control device may control the door to stop closing by, for example, controlling the door drive device to stop driving the door to close.
[0068] Exemplarily, the control device may determine whether the automatic closing of the door reaches the first limit position through a first limit position switch, for example.
[0069] If the control device does not receive the above-mentioned first instruction when the door body automatically closes and reaches the first limit position, it means that the user has not touched the door body. Optionally, the control device can, for example, continue to control the door body to automatically close until it is determined that the door body is closed.
[0070] As a possible implementation, if the control device continues to receive the first instruction within a first preset time after the door stops closing, that is, the user still touches the touch panel within the first preset time, the control device may output an alarm prompt. The alarm prompt may be used to prompt the user that there is a risk of pinching the hand.
[0071] Optionally, the first preset duration may be pre-stored in the control device, for example.
[0072] For example, the control device may send a finger pinching risk instruction signal to a display panel of the refrigerator, and after receiving the signal, the display panel emits a beeping sound to remind the user that there is a finger pinching risk.
[0073] Through the above method, the user is promptly reminded of the risk of finger pinching, the flexibility of the refrigerator's automatic door closing to prevent finger pinching is improved, and the user experience is further improved.
[0074] As a possible implementation, the control device may also receive an automatic door opening instruction through the above-mentioned sensing electrode. For example, the control device may also determine that an automatic door opening instruction has been received when the duration of continuous receipt of the first instruction is greater than or equal to a second preset duration. The control device may control the door to open automatically in response to the automatic door opening instruction. Through the above method, the refrigerator may realize automatic door opening based on the sensing electrode, thereby improving the flexibility of the refrigerator.
[0075] Optionally, the second preset duration may be pre-stored in the control device, for example.
[0076] Exemplarily, the control device may determine that an automatic door opening instruction is received when the door body is in a closed state and the duration of continuous receipt of the first instruction is greater than or equal to a second preset duration. In other words, the user may trigger the automatic door opening instruction by, for example, long pressing the touch panel.
[0077] Figure 4 Schematic diagram of the structure of another touch sensing device. Figure 5 FIG. 1 is a schematic diagram of the structure of another touch sensing device. Figure 4 As shown, the touch sensing device provided by the present application is compared with Figure 4 The touch sensing device shown can sense the approach or touch of a human body over a large area; compared to Figure 5 The touch sensing device shown in the present application can realize the sensing of human body approach or touch over a large area, which requires less space and uses less materials, thus reducing the complexity of the refrigerator. Figure 5 The implementation method using multiple springs shown requires multiple welding, and the consistency of the springs will affect the consistency of the sensing, resulting in poor sensing accuracy. The touch sensing device provided by the present application improves the reliability and consistency of the refrigerator sensing the human body by using the copper pads on the printed circuit board as the sensing click.
[0078] For example, Figure 6 This is a schematic diagram of a control circuit provided in this application. Figure 6As shown, the IC1 chip can be used as the MCU chip of the touch sensing device to sense the approach or touch of a human body and produce a corresponding output level for the sensing.
[0079] ZD1 can be a TVS diode, which is used to effectively absorb and dissipate the energy of overvoltage. Thereby protecting the stability and reliability of the circuit. The electrolytic capacitor E1 and the ceramic capacitor C1 can effectively filter out the ripple voltage and improve the stability of the power supply. At the same time, it can also be used as a decoupling capacitor to reduce noise interference in the circuit. The R11 resistor, the N1 transistor, the R2 resistor, the D1 anti-static diode, the R1 resistor, and the C4 capacitor constitute a level output isolation circuit. R3 and R4 are the program burning circuits. The R6 resistor and KEY1 constitute the sensing circuit. In other words, the control circuit can be connected to the sensing electrode through the KEY1.
[0080] For example, Figure 7 This is a schematic diagram of the structure of another refrigerator provided in this application. Figure 7 As shown, a touch-sensing control panel (the aforementioned control panel) may be provided on the door of the refrigerator, and a door touch-sensing decorative strip (the aforementioned touch panel) may be provided on the control panel. When a human body approaches or touches the door touch-sensing decorative strip, the 28-pin of the chip IC1 outputs a low level, at which time the N1 transistor is turned on, the left end of the R1 resistor is at a low level, and the interference signal is filtered out through the R1 and C4 resistor-capacitor absorption circuits, and a low level is output. The control device receives the low-level signal and controls the motor to suspend operation through the motor drive module. When no human body approaches or touches, the 28-pin of the chip IC1 outputs a high level, at which time the N1 transistor is turned off, the left end of the R1 resistor is at a high level, and the interference signal is filtered out through the R1 and C4 resistor-capacitor absorption circuits, and a high level is output; the control device receives the high-level signal and controls the motor to run.
[0081] Based on Figure 6 The control circuit shown, Figure 8 A schematic diagram of a refrigerator automatic door closing method provided in this application. Figure 8 As shown, when the user issues an automatic door closing command, the main controller MCU reads the current refrigerator door position signal and determines whether the position has reached the risk of hand pinching position - the first limit position based on the read freezer door position information.
[0082] For example, Fig. 9 This is a schematic diagram of the structure of a refrigerator provided in this application. Fig. 9 As shown, the refrigerator may include a first limit position switch and a second limit position switch.
[0083] If the refrigerator door does not reach the first limit position switch, that is, it is still within the safe range (no risk of pinching fingers), the main controller MCU continues to send a forward door closing signal to the motor controller, and the MCU continues to monitor the position information of the refrigerator door.
[0084] If the refrigerator door reaches the first limit position switch, that is, it is not within the safe range (there is a risk of pinching fingers), the main controller MCU reads the touch signal of the door. If the MCU senses a touch signal on the refrigerator door, it means that the door is about to close, but it detects that a finger is still on the door, and there is a risk of pinching fingers. At this time, the main controller MCU sends a motor pause signal to the motor controller to drive the motor to pause the door closing action.
[0085] The timing starts after the main controller MCU sends a motor pause signal to the motor controller for the first time. If the accumulated pause time does not exceed time T1, the timing returns to the touch signal reading node.
[0086] If the pause time exceeds T1, and the touch blocking signal still exists, the main controller MCU still sends the finger-pinching risk command signal to the display panel, and the display panel emits a beep after receiving it to remind the user of the abnormality. Next, return to continue reading the refrigerator door touch signal for judgment.
[0087] If the refrigerator door reaches the first limit position switch and the position is not within the safe range (i.e. there is a risk of pinching fingers), the main controller MCU reads the touch signal of the door, and if the MCU does not receive the touch sensing signal sent by the touch control panel on the refrigerator door, it means that the door is close to closing and there is no risk of pinching fingers. At this time, the main controller MCU sends a forward door closing signal to the motor controller to drive the motor to continue to close the door. If the refrigerator door does not reach the closed limit position, it will continue to return to reading the refrigerator door touch signal; when the refrigerator door reaches the closed limit position, the MCU sends a motor stop signal to the motor controller, and the door closing drive motor stops.

[0090] The output module 12 is used to output a first instruction indicating that a user touches the touch panel to the control device when the control circuit senses that a user touches the touch panel.
[0091] The control module 13 is used to control the door body to automatically close in response to the automatic closing instruction through the control device, and control the door body to stop closing when receiving the first instruction.
[0092] Optionally, the output module 12 is specifically configured to determine that a user touches the touch panel when the capacitance value between the sensing electrode and the user's finger is greater than or equal to a preset capacitance value, and output the first instruction to the control device, wherein the capacitance value is related to the area of the sensing electrode and the thickness of the touch panel.
