[0045] The push-type switch assembly 1 provided in the present application is applied to a refrigerator. The push-type switch assembly 1 includes a base 10, a pressure plate 20 and a sensing assembly 30. The base 10 is used as a mounting carrier for mounting the pressure plate 20 and the sensing assembly 30. The pressure plate 20 is used for a user to press to trigger the sensing assembly 30 to control the refrigerator to discharge ice or water. The pressure plate 20 may include a first end and a second end separated from each other. The first end of the pressure plate 20 is rotatably connected to the base 10, and the second end of the pressure plate 20 can be close to or away from the base 10. The sensing assembly 30 is used to sense the state change of the pressure plate 20 and output an electrical signal that can control the refrigerator to discharge ice or water according to the state change of the pressure plate 20. The sensing assembly 30 is arranged on the base 10 and is arranged opposite to the second end of the pressure plate 20. When the second end of the pressure plate 20 changes from being away from the base 10 to being close to the base 10, the sensing assembly 30 is triggered to control the refrigerator to discharge ice or water. The present application uses a sensing component 30 to sense the state change of the pressure plate 20, and outputs an electrical signal accordingly to control the refrigerator to discharge ice or water. The invention is simple to manufacture and easy to operate, which is beneficial to improving the accuracy of the refrigerator in executing functional programs and improving the user's operating experience.
[0046] For the convenience of description in the specification of the present application, each embodiment of the present application takes the implementation method that when the second end of the pressure plate 20 changes from being away from the base 10 to being close to the base 10, the sensing component 30 can be triggered to control the refrigerator to discharge ice or water as an example, and the design proposed in the present application is described and introduced as follows. It can be understood that in some embodiments of the present application, it can also be set that when the second end of the pressure plate 20 changes from a state close to the base 10 to a state away from the base 10, the sensing component 30 is triggered to control the refrigerator to discharge ice or water. The implementation method is similar to the principle of the implementation method that when the second end of the pressure plate 20 changes from a state away from the base 10 to a state close to the base 10, the sensing component 30 is triggered to control the refrigerator to discharge ice or water. For details, please refer to the relevant description in the present application.
[0047] See also Figure 4 and Figure 5 , Figure 5A schematic diagram of the structure of the base 10 provided in an embodiment of the present application. The base 10 may be provided with a concave cavity 101, the pressing plate 20 is arranged toward the concave cavity 101, the first end of the pressing plate 20 is rotatably connected to one end of the base 10 (for ease of description, the one end of the base 10 is referred to as the hinged end of the base 10 below), the second end of the pressing plate 20 is arranged opposite to the other end of the base 10 (for ease of description, the other end of the base 10 is referred to as the trigger end below) and can move toward or away from the other end of the pressing plate 20, and the sensing component 30 is installed in the concave cavity 101 and is arranged opposite to the second end of the pressing plate 20, so that when the second end of the pressing plate 20 approaches the base 10, the pressing plate 20 can trigger the sensing component 30.
[0048] See also Figure 5 and Figure 6 , Figure 6 The schematic diagram of the structure of the pressing plate 20 provided in the embodiment of the present application. The base 10 may include a base 11 and two oppositely arranged side walls 12, the base 11 has two ends opposite to the two ends of the pressing plate 20, the two ends of the base 11 are recessed in the direction away from the pressing plate 20 to form a cavity 101, the two side walls 12 are respectively arranged on both sides between the two ends of the base 11 and extend toward the two ends of the base 11, and the ends of the two side walls 12 close to the first end of the pressing plate 20 may each be provided with a through hole 121, and accordingly, the first end of the pressing plate 20 may be provided with a rotating shaft 22 extending toward the side wall 12, and the rotating shaft 22 is rotatably fitted in the through hole 121, so that the first end of the pressing plate 20 is rotatably arranged on the base 10.
[0049] See also Figure 3 In order to enable the second end of the pressing plate 20 to automatically return to its original position in a direction away from the base 10 after the pressing force acting on the pressing plate 20 is removed, the push switch assembly 1 may further include an elastic element 40, which is connected between the base 10 and the pressing plate 20. When the pressing force acting on the pressing plate 20 is removed, the elastic element 40 will drive the second end of the pressing plate 20 away from the base 10. Exemplarily, the elastic element 40 can be a torsion spring, which is sleeved on the rotating shaft 22. The torsion spring includes a torsion spring body and two torsion arms extending outward from both ends of the torsion spring body in a direction away from the torsion spring body. The torsion spring body is sleeved on the rotating shaft 22 of the pressure plate 20, one torsion arm abuts against the base 10, and the other torsion arm abuts against the pressure plate 20. When the second end of the pressure plate 20 is pressed, the second end of the pressure plate 20 can rotate relative to the base 10. At the same time, the two torsion arms of the torsion spring can approach each other to generate elastic potential energy. When the pressing force on the pressure plate 20 is removed, the elastic potential energy can be converted into elastic force to make the second end of the pressure plate 20 be in a state away from the base 10 again.
[0050] Please continue reading Figure 5 and Figure 6, the end of the base 10 opposite to the second end of the pressing plate 20 may also be provided with a slot 102. Correspondingly, the second end of the pressing plate 20 may extend toward the side of the base 10 to form a limiting structure 23, and at least a portion of the limiting structure 23 is slidably disposed in the slot 102 to limit the rotation range of the pressing plate 20. Exemplarily, the slot 102 may be disposed at the trigger end of the base 10. Specifically, the end of the base 11 opposite to the second end of the pressing plate 20 may be provided with an end wall 13 protruding toward the pressing plate 20, and the end of the end wall 13 separated from the base 11 may be provided with a limiting flange 14, and the limiting flange 14 may be protruding toward the hinged end of the base 10, thereby forming a limiting space of the slot 102 between the end wall 13, the limiting flange 14, and the base 11. Accordingly, the limiting structure 23 may be formed by extending toward the base 10 at the second end of the pressing plate 20 and on the side opposite to the base 10, and the limiting structure 23 may include an extension The extension portion 231 is formed by extending from the pressure plate 20 toward the base 10, and the hooking portion 232 is arranged at the end of the extension portion 231 away from the pressure plate 20 and extends in a direction parallel to the pressure plate 20 or slightly inclined to the pressure plate 20. The hooking portion 232 extends into the card slot 102. When the second end of the pressure plate 20 rotates toward or away from the trigger end of the base 10, the second end of the pressure plate 20 can be abutted against the base 11 or hooked on the limiting flange 14 with the hooking portion 232, thereby limiting the rotational movement of the second end of the pressure plate 20. When the second end of the pressure plate 20 moves toward or away from the base 10, the hooking portion 232 of the limiting structure 23 will be limited to move only within the limiting space forming the card slot 102. Therefore, it can prevent the pressure plate 20 from being pressed beyond the range, thereby preventing other structures or components on the pressure plate 20 from being damaged due to interference with the base 10, and preventing the pressure plate 20 from returning beyond the range and preventing components installed on the base 10 from being exposed, thereby ensuring the beautiful appearance and enhancing the user experience.
[0051] The refrigerator may include a control system (not shown in the figure), an ice-making mechanism (not shown in the figure) and a water-discharging mechanism (not shown in the figure). The control system is electrically connected to the sensing component 30, the ice-making mechanism and the water-discharging mechanism. The control system receives the electrical signal of the sensing component 30 and can control the ice-making mechanism to execute the functional program of discharging ice or control the water-discharging mechanism to execute the functional program of discharging water according to the electrical signal.
[0052] See also Figure 7 , Figure 7 1 is a schematic diagram of the installation of the induction component 30 provided in the first embodiment of the present application. In some embodiments, the induction component 30 may include an inductive proximity switch 31, and a metal body 24 is provided on the side of the second end of the pressing plate 20 facing the inductive proximity switch 31. When the second end of the pressing plate 20 approaches the base 10, the metal body 24 approaches the inductive proximity switch 31, and the inductive proximity switch 31 is triggered to control the refrigerator to discharge ice or water.
[0053] It should be noted that the inductive proximity switch 31 is a position sensor with a switch output. The switch output refers to the switch signal generated by the system as the output. The switch output signal is a discrete binary signal. The switch output signal can be generated according to the logical rules and control strategies of the system. For example, in the embodiment of the present application, when the inductive proximity switch 31 determines that a certain condition is satisfied, for example, after determining that it is triggered by the metal body 24, the inductive proximity switch 31 can generate a switch output signal, indicating that the control system of the refrigerator needs to be controlled. Usually, the inductive proximity switch 31 is composed of an LC high-frequency oscillator and an amplification processing circuit. When the metal body 24 approaches the oscillating induction head that can generate an electromagnetic field, an eddy current is generated inside the metal body 24. This eddy current reacts to the proximity switch, causing the proximity switch to attenuate its oscillation ability and change the parameters of the internal circuit, thereby identifying whether the metal body 24 is approaching, and then being able to control the switch on or off.
[0054] See also Figure 8 , Figure 8 3 is an installation diagram of the induction assembly 30 provided in the second embodiment of the present application. In some embodiments, the induction assembly 30 may include a Hall type proximity switch 32, and a magnet 25 is provided on the side of the second end of the pressing plate 20 facing the Hall type proximity switch 32. When the second end of the pressing plate 20 approaches the base 10, the magnet 25 approaches the Hall type proximity switch 32, and the Hall type proximity switch 32 is triggered to control the refrigerator to discharge ice or water.
[0055] It should be noted that the Hall type proximity switch 32 is made based on the Hall effect principle and is made by integrated packaging and assembly technology. The Hall effect refers to an effect in which the interaction between the current and the magnetic field in the conductive material generates an electromotive force. The Hall type proximity switch 32 can convert the magnetic input signal into an electrical signal in practical applications, and has the characteristics of no electric shock, low power consumption, long service life, high response frequency, etc. In actual use, when the magnet 25 is close to the Hall type proximity switch 32, the magnetic induction intensity of the magnet 25 to the Hall type proximity switch 32 gradually increases and reaches a preset value, the trigger inside the Hall type proximity switch 32 flips, and the output level state of the Hall switch also flips accordingly, so that the refrigerator can execute the function program of discharging ice or water.
[0056] See also Fig. 9 , Fig. 93 is a schematic diagram of the structure of the sensing component 30 provided in the third embodiment of the present application. In some embodiments, the sensing component 30 may further include an ultrasonic proximity switch 33, and a shielding rib 26 is convexly provided on the second end of the pressing plate 20 facing the ultrasonic proximity switch 33. When the second end of the pressing plate 20 approaches the base 10, the reflective rib 26 approaches the ultrasonic proximity switch 23, and the ultrasonic proximity switch 33 is triggered to control the refrigerator to discharge ice or water.
[0057] It should be noted that the ultrasonic proximity switch 33 provided in the embodiment of the present application can be a reflective ultrasonic proximity switch or a through-beam ultrasonic proximity switch. The ultrasonic proximity switch 33 is a sensor device that uses ultrasonic waves to detect and judge the approaching or distant state of an object. It usually adopts pulse echo technology, which can measure the distance between the detector and the object to be measured, and realize the corresponding control signal output accordingly. In the embodiment of the present application, taking the reflective ultrasonic proximity switch as an example, when the second end of the pressing plate 20 is in a state of being away from the base 10, at least part of the sound wave signal emitted by the ultrasonic proximity switch 33 can be reflected by the base side wall 12 opposite to the transmitting end of the ultrasonic proximity switch 33 and then received by the ultrasonic proximity switch 33 again, and the ultrasonic proximity switch 33 obtains the first distance information and converts it into a first electrical signal. When the second end of the pressing plate 20 is close to the base 10 and finally makes the shielding rib 26 opposite to the ultrasonic proximity switch 33, at least part of the sound wave signal emitted by the ultrasonic proximity switch 33 can be reflected by the shielding rib 26 and then received by the ultrasonic proximity switch 33 again, and the ultrasonic proximity switch 33 obtains the second distance information and converts it into a second electrical signal. The first electrical signal and the second electrical signal can be two different switch signals, thereby causing the output state of the ultrasonic proximity switch 33 to change accordingly, thereby controlling the refrigerator to execute the functional program of discharging ice or water.

In the embodiment of the present application, the sensing component 30 can be a photoelectric sensor 34, which includes the above-mentioned transmitter 341 and receiver 342, wherein the transmitter 341 is used to emit visible or invisible light, and the receiver 342 is used to receive the light emitted by the transmitter 341 and convert the optical signal into an electrical signal. In addition to the above-mentioned transmitter 341 and receiver 342, the photoelectric sensor 34 may also include a detection circuit (not shown in the figure), and the receiver 342 converts the optical signal into an electrical signal and transmits it to the detection circuit. The detection circuit obtains the electrical signal and filters out the effective signal, and then transmits the effective information to the control system of the refrigerator, and the refrigerator executes the ice or water output program accordingly.
[0059] In some embodiments, the transmitter 341 includes a first surface 3410 facing the side of the receiver 342, and the receiver 342 includes a second surface 3420 facing the side of the transmitter 341. In the normal direction perpendicular to the first surface 3410, the first surface 3410 is opposite to the second surface 3420 and the projection of the first surface 3410 is located within the projection range of the second surface 3420, so that the receiver 342 can fully receive the optical signal emitted by the transmitter 341, thereby ensuring that the receiver 342 can receive the optical signal of the transmitter 341, so that the refrigerator can be accurately triggered to execute the functional program of discharging ice or water.

When the shielding rib 26 is between the first electrode plate 351 and the second electrode plate 352, the medium between the first electrode plate 351 and the second electrode plate 352 is air and the shielding rib 26, and the dielectric constant between the first electrode plate 351 and the second electrode plate 352 changes to a second value, and the first value and the second value are unequal values. The capacitive proximity switch 35 may also include a detection circuit (not shown in the figure). In actual use, due to the change in the dielectric constant, the capacitance value of the capacitive proximity switch 35 changes accordingly. One of the electrode plates (such as the second electrode plate 352) converts the change in the capacitance value into an electrical signal and transmits it to the detection circuit. The detection circuit then filters out the effective signal and transmits the signal to the control system of the refrigerator, and the refrigerator executes the functional program of discharging ice or water accordingly.
[0062] like Fig.13 , Fig.13 A schematic diagram of the structure of a refrigerator provided in an embodiment of the present application. Based on the push-type switch assembly 1 provided in an embodiment of the present application, the refrigerator 100 provided in an embodiment of the present application may include an ice-making mechanism (not shown), a water-discharging mechanism (not shown) such as a water valve, and the push-type switch assembly 1 provided in any embodiment of the present application, wherein the push-type switch assembly 1 is electrically connected to the ice-making mechanism and the water-discharging mechanism to control the ice-making mechanism to discharge ice or to control the water-discharging mechanism to discharge water.
[0063] The refrigerator may also include a control system (not shown). In some embodiments, the door of the refrigerator may be provided with a function selection switch (not shown). Exemplarily, the function selection switch may include a first switch, a second switch and a third switch, wherein the first switch is used to control the ice maker to discharge whole ice, the second switch is used to control the ice maker to discharge crushed ice, and the third switch is used to control the ice maker to discharge cold water. The function switch, the push-type switch assembly 1, the ice making mechanism, and the water discharge mechanism are all electrically connected to the control system of the refrigerator.
[0064] When operating the refrigerator during actual use, if whole ice is needed, the user can press the first switch and then press the pressure plate 20 of the push-type switch assembly 1, and the ice-making mechanism can produce whole ice. Similarly, if crushed ice is needed, the user can press the second switch and then press the pressure plate 20 of the push-type switch assembly 1, and the ice-making mechanism can produce crushed ice. If cold water is needed, the user can press the third switch and then press the pressure plate 20 of the push-type switch assembly 1, and the water discharge mechanism can discharge cold water. In this way, different drinking needs of users can be met. Using the push-type switch assembly 1 to allow the control system of the refrigerator to control the ice discharge mechanism to discharge ice or control the water discharge mechanism to discharge water is conducive to ensuring the accuracy and reliability of operation.
[0065] Compared with the traditional implementation of using a micro switch to touch the refrigerator to discharge ice or water, the beneficial effects of the push-type switch component and the refrigerator provided in the embodiment of the present application are: on the one hand, by using the sensing component to sense the state change of the pressure plate, and outputting an electrical signal to control the refrigerator to discharge ice or water, it is beneficial to reduce the number of components used and make its installation easier and more reliable. Since the sensing component in the present application is non-contact triggered, there is no problem of wear and tear due to long-term use, which is beneficial to accurately trigger the function program of the refrigerator and improve the operating experience; on the other hand, by opening a card slot on the base, a limiting structure is formed by extending the pressure plate toward the side of the base, and the end of the limiting structure is limited to being able to move only in the card slot, thereby limiting the rotation range of the pressure plate, and effectively preventing the pressure plate from being pressed out of range or returning out of range.
