[0002] With the development of society and the continuous improvement of people's living standards, refrigerators are becoming more and more intelligent. During the use of refrigerators, it is often necessary to detect the state of the door, that is, to confirm whether the door is in a closed state or an open state, and then apply specific control to the refrigerator accordingly. For example, when the door is closed, the light inside the refrigerator compartment is turned off; when the door is open, the light is turned on. At present, a mechanical switch is usually used to determine the switch state of the door. The mechanical switch determines the switch state of the door by pressing the door and the switch in physical contact.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0004] Since the gap between the door and the box is exposed to the user, the mechanical switch is also exposed to the user, so that the user can easily touch the mechanical switch. In the case where the user accidentally touches the mechanical switch, the main control board will incorrectly determine the state of the door.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0029] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure.

It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0031] Unless otherwise stated, the term "plurality" means two or more.

[0032] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0033] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0034] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0035] Combination Figure 1 As shown, an embodiment of the present disclosure provides a door switch assembly, including a door shaft 101, a first gear 102, a generator 103 and a door state recognition circuit 104. The first gear 102 is coaxially connected to the door shaft 101. The first gear 102 is used to trigger the generator 103 to generate a first electric energy with a direction when the door shaft 101 rotates. The generator 103 is electrically connected to the door state recognition circuit 104, and the generator 103 is used to transmit the first electric energy with a direction to the door state recognition circuit 104. The door state recognition circuit 104 is used to determine the state of the door according to the first electric energy with a direction. The door state is used to characterize whether the door is opening or closing.

[0036] The door switch assembly provided by the embodiment of the present disclosure is used to generate the first electric energy with a direction through the first gear triggering the generator. The first electric energy with a direction is transmitted to the door state recognition circuit through the generator, so that the door recognition circuit can determine whether the door is in an open state or a closed state according to the first electric energy with a direction. In this way, even if the user accidentally touches the first gear and other door switch assemblies, it will not cause the door state recognition circuit to mistakenly identify the door state, so that the door state can be determined more accurately.

[0037] In some embodiments, the door body is applied to a box body with an opening, and the door body is used to close the opening. The door body is in an open state to indicate that the door body is away from the opening. The door body is in a closed state to indicate that the door body is close to the opening until the opening is closed.

[0038] Optionally, the door state identification circuit includes: a voltage stabilizing circuit board and a main control board. The voltage stabilizing circuit board is electrically connected to the main control board, and the voltage stabilizing circuit board is used to output an electrical signal corresponding to the first electrical energy with a direction to the main control board. The main control board is used to determine the door state according to the electrical signal.

[0039] In some embodiments, the voltage stabilizing circuit board is used to convert the first electric energy with direction into a high-level pulse signal. Since the speed of the door body each time it is opened or closed may be different, the first electric energy generated by the rotation of the first coil of the generator may also have different magnitudes. By using the voltage stabilizing circuit board to convert the first electric energy with direction into a high-level pulse signal, the first electric energy of different magnitudes can be converted into the same electrical signal, so that the main control board can determine the state of the door body according to the electrical signal.

[0040] Furthermore, the voltage stabilizing circuit board converts the first electric energy in different directions into high-level pulse signals of different I / O ports.

[0041] Optionally, the main control board is also used to record the number of times the door is opened and the opening time.

[0042] Optionally, the door switch assembly further includes a second gear. The second gear is meshed with the first gear. The first gear triggers the generator to generate a first electric energy with a direction through the second gear. Further, the pitch circle of the first gear is larger than the pitch circle of the second gear. In this way, when the first gear rotates, the number of rotations of the second gear will be larger than the number of rotations of the first gear, thereby driving the first coil to rotate multiple times to generate more first electric energy, thereby reducing the possibility of misidentifying the door state due to insufficient electric energy.

[0043] In some embodiments, the pitch circle of the first gear is 3 to 5 times the pitch circle of the second gear.

[0044] In some embodiments, when the rotation angle of the first gear is between the first preset angle and the second preset angle, the gear teeth of the first gear mesh with the gear teeth of the second gear, wherein the first preset angle is greater than 0, and the second preset angle is less than the rotation angle of the first gear when the door is fully opened.

[0045] Combination Figure 2 As shown, the embodiment of the present disclosure provides a schematic diagram of the positional relationship between the first gear and the second gear when the door is fully closed. When the door is fully closed, the gear teeth of the first gear 102 and the gear teeth of the second gear 105 are in a non-engaged state.

[0046] Combination Figure 3As shown, the embodiment of the present disclosure provides a schematic diagram of the positional relationship between the first gear and the second gear when the rotation angle of the first gear is from the first preset angle to the second preset angle. It can be seen that the gear teeth of the first gear 102 are meshed with the gear teeth of the second gear 105.

[0047] Combination Figure 4 As shown, the embodiment of the present disclosure provides a schematic diagram of the positional relationship between the first gear and the second gear when the door is fully opened. When the door is fully opened, the gear teeth of the first gear and the gear teeth of the second gear are in a non-engaged state.

[0048] Furthermore, when the second gear rotates, it drives the first coil of the generator to rotate to cut the magnetic flux lines to generate the first electric energy with a direction. Furthermore, when the door body is in an open state, the second gear drives the first coil of the generator to rotate forward along with the rotation of the first gear, generating the first electric energy in the first direction, that is, positive electric energy. When the door body is in a closed state, the second gear drives the first coil of the generator to rotate reversely along with the rotation of the first gear, generating the first electric energy in the second direction, that is, negative electric energy.

[0049] Optionally, the door switch assembly further includes a third gear and an energy storage element. The third gear is coaxially connected to the door shaft; the third gear is used to trigger the generator to generate the second electric energy when the door shaft rotates. The energy storage element is electrically connected to the door state recognition circuit, and is used to store the second electric energy, and to supply power to the door state recognition circuit when the external power supply of the door state recognition circuit is powered off. Since the existing mechanical switches for determining the state of the door body need to supply power to the door state recognition circuit for their operation. However, when the external power supply of the door state recognition circuit is powered off, the state of the door body cannot be determined. The mechanical energy generated by opening or closing the door body is converted into electric energy and stored in the energy storage element. At the same time, when the external power supply of the door state recognition circuit is powered off, the energy storage element is used to supply power to the door state recognition circuit, so that even if the external power supply of the door state recognition circuit is powered off, the door state recognition circuit can still work normally. Thereby reducing the probability that the door state recognition circuit cannot record the state of the door body.

[0050] In some embodiments, the energy storage element is disposed in a voltage stabilizing circuit board.

[0051] Furthermore, the energy storage element is electrically connected to the main control board, and is used to supply power to the main control board when the external power supply of the main control board is powered off. Whether the main control board is used to determine the state of the door body, or to record the number of times the door body is opened and the length of time the door is opened, the premise is that the main control board is powered on. If an emergency occurs in the external power supply of the main control board, the main control board cannot continue to be powered. The main control board will no longer be able to determine the state of the door body, let alone record the number of times the door is opened and the length of time the door is opened. The second electric energy is generated by using the third gear to drive the second coil of the generator to rotate to cut the magnetic flux lines. The second electric energy is stored in the energy storage element, so that when the external power supply of the main control board is powered off, the energy storage element can continue to supply power to the main control board, so that the main control board can still determine the state of the door body and record the number of times the door is opened and the length of time the door is opened.

[0052] In some embodiments, the door switch assembly further includes a fourth gear. The fourth gear is meshed with the third gear, and the third gear triggers the generator to generate the second electrical energy through the fourth gear. Further, the pitch circle of the third gear is larger than the pitch circle of the fourth gear. Thus, when the third gear rotates, the number of rotations of the fourth gear will be larger than the number of rotations of the third gear, thereby driving the second coil to rotate multiple times to generate more second electrical energy and increase the stored electrical energy in the energy storage element.

[0053] Furthermore, when the fourth gear rotates, it drives the second coil of the generator to rotate so as to cut the magnetic flux lines and generate the second electric energy.

[0054] Optionally, the pitch circle of the third gear is 3 to 5 times the pitch circle of the fourth gear.

[0055] In some embodiments, when the door body is not in a fully open state and / or when the door body is not in a fully closed state, the gear teeth of the third gear mesh with the gear teeth of the fourth gear.

[0056] Combination Figure 5 As shown, the embodiment of the present disclosure provides a position relationship diagram of the third gear and the fourth gear when the door body is fully closed. It can be seen that the gear teeth of the third gear 106 are not meshed with the gear teeth of the fourth gear 107.

[0057] Combination Figure 6 As shown, the embodiment of the present disclosure provides a position relationship diagram of the third gear and the fourth gear when the door body is not fully closed and not fully opened. It can be seen that the gear teeth of the third gear 106 are meshed with the gear teeth of the fourth gear 107.

[0058] Combination Figure 7 As shown, the embodiment of the present disclosure provides a position relationship diagram of the third gear and the fourth gear when the door body is fully opened. It can be seen that the gear teeth of the third gear 106 are not meshed with the gear teeth of the fourth gear 107.

[0059] Combination Figure 8 As shown, an embodiment of the present disclosure provides a schematic diagram of a door switch assembly. It includes: a generator, a second gear 105, a fourth gear 107, a voltage stabilizing circuit board 113, an energy storage element 112 and a main control board 114. The generator includes a first coil 108, a second coil 109, an N magnetic pole 110 and an S magnetic pole 111. The second gear 105 is connected to the first coil 108, and the second gear 105 is used to drive the first coil 108 to rotate when rotating. The fourth gear 107 is connected to the second coil 109. The fourth gear 107 is used to drive the second coil 109 to rotate when rotating. Since there is a magnetic field between the N magnetic pole 110 and the S magnetic pole 111, when the first coil and the second coil rotate, the magnetic flux lines can be cut to generate electrical energy. One end of the first coil 108 is connected to the input port V1 of the voltage stabilizing circuit board 113, and the other end is connected to the GND port of the voltage stabilizing circuit board 113. One end of the second coil 109 is connected to the input port V2 of the voltage stabilizing circuit board 113, and the other end is connected to the GND input port of the voltage stabilizing circuit board 113. Among them, the GND input port is used for grounding. The output ports DOOR+, DOOR-, +5V and GND of the voltage stabilizing circuit board 113 are all electrically connected to the main control board. DOOR+ is used to output the first electric energy representing that the door body is in an open state to the main control board. DOOR- is used to output the first electric energy representing that the door body is in a closed state to the main control board. The energy storage element is used to power the main control board through the output port +5V and the output port GND. In this way, the generator is triggered by the first gear to generate the first electric energy with a direction. And the first electric energy with a direction is transmitted to the door state recognition circuit through the generator, so that the door recognition circuit can determine whether the door body is in an open state or a closed state according to the first electric energy with a direction. In this way, even if the user accidentally touches the door switch components such as the first gear, it will not cause the door state recognition circuit to mistakenly identify the door state, so that the door state can be determined more accurately. At the same time, when the external power supply of the door state recognition circuit is cut off, the energy storage element is used to power the door state recognition circuit, so that even if the external power supply of the door state recognition circuit is cut off, the door state recognition circuit can still work normally, thereby reducing the probability that the door state recognition circuit cannot record the door state.
