Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a refrigerator gas pressure switch and a refrigerator. Background Technology

[0002] With the rapid development of smart home technology, refrigerators, as an important component of home appliances, are receiving increasing attention for their intelligent functions. Among these, intelligent door opening technology, by simplifying user operation and improving ease of use, has become one of the key directions for refrigerator technology innovation. Traditional refrigerators typically rely on manual door opening, while intelligent door opening technology uses sensors or auxiliary devices to achieve automatic door opening, providing users with a more convenient user experience.

[0003] In existing technologies, a pressure switch assembly connected to the refrigerator's interior is typically used to achieve the intelligent door opening function of a refrigerator. This assembly includes a pressure detection element and a chamber connected to the refrigerator's interior. As pressure changes occur within the chamber, the pressure detection element controls the refrigerator door to open when it detects that the pressure has reached a preset value. Because this pressure change is generated between the low-temperature gas inside the refrigerator and the ambient temperature gas outside, the temperature difference between the two causes condensation to easily form on the pressure detection element. This condensation may adhere to the pressure detection element, leading to problems such as short circuits, component corrosion, or decreased sensitivity. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator pressure switch that can solve the above problems.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator pressure switch is installed on the refrigerator body, the refrigerator pressure switch comprising:

[0007] A pneumatic switch assembly is mounted on the housing;

[0008] A pressure transmission assembly includes a base and a button. The base is mounted on the housing. The button is located on the base and is sealed to the base. One end of the button away from the base is attached to the refrigerator door. The button and the base enclose a cavity, and the cavity is connected to the pneumatic switch assembly.

[0009] The button is capable of retracting the base in response to the displacement of the refrigerator door, and causing the gas in the cavity to be forced into the pressure switch assembly, resulting in a change in the air pressure inside the pressure switch assembly. The pressure switch assembly responds to the change in air pressure to control the refrigerator door to open.

[0010] Understandably, this application utilizes a pressure transmission assembly comprising a base and a button. The base secures the pressure transmission assembly, and the button, which is confined to the base and retractable relative to it, abuts against the refrigerator door. When the refrigerator door shifts, the button retracts to the base, forcing gas from the cavity into the pressure switch assembly. This causes a change in the internal pressure of the pressure switch assembly. When the pressure change reaches a preset value, the refrigerator door is opened. Because the gas in the internal cavity of the pressure transmission assembly is not at a low temperature, there is no temperature difference between the two sides of the pressure switch assembly after it is pressed in, thus preventing condensation. This effectively avoids problems such as short circuits, device corrosion, or decreased sensitivity caused by condensation adhering to the pressure detection element.

[0011] In one embodiment, the pressure transmission assembly further includes a guide member disposed within the cavity and fixedly connected to the base, and the button is sleeved on the outside of the guide member and is movable along the guide member.

[0012] It is understandable that by setting up a guide, the button can be guided when it retracts into the base. When the button extends or retracts relative to the base, it can move along the guide, thus improving the stability of the button's extension and retraction.

[0013] In one embodiment, a connecting hole is provided on the side wall of the base away from the button, the guide is configured as a hollow guide post, the hollow guide post is fixed to the side wall and located on the outer periphery of the connecting hole, and a gap is formed between the hollow guide post and the button;

[0014] The connecting hole is connected to the pressure transmission assembly via a pipeline.

[0015] In one embodiment, the pressure transmission assembly further includes an elastic element, which is sleeved on the hollow guide post, with one end abutting against the side wall and the other end abutting against the button;

[0016] When the button retracts into the base, the elastic element is compressed and can apply a force to the button to reset it.

[0017] In one embodiment, the pressure transmission assembly further includes a seal disposed between the button and the base, thereby sealing the button and the base together.

[0018] In one embodiment, a closed annular groove is provided around the outer peripheral surface of the button in the circumferential direction. The sealing element is configured as an O-ring. The O-ring is fitted onto the button and partially located within the annular groove. The button's circumferential direction abuts against and seals the base through the O-ring.

[0019] In one embodiment, the pneumatic switch assembly includes a movable electrode, a fixed electrode, and a signal output component, wherein the movable electrode and the fixed electrode are disposed at a distance from each other, and the signal output component is electrically connected to the fixed electrode;

[0020] The movable electrode can respond to the change in air pressure and move closer to the fixed electrode. When the distance between the two reaches a preset value, the signal output device outputs an electrical signal to control the refrigerator door to open.

[0021] In one embodiment, the pneumatic switch assembly includes a housing and an elastic seal, the elastic seal being sealed to the housing and enclosing a pneumatic cavity, the pneumatic cavity communicating with the chamber, and the active electrode being disposed on the side of the elastic seal away from the pneumatic cavity;

[0022] The elastic seal deforms in response to the change in air pressure, which can move the movable electrode closer to the fixed electrode.

[0023] It is understandable that by setting up an elastic seal and placing the active electrode on the elastic seal, it is possible to better respond to changes in air pressure and deformation. Since the elastic seal is prone to deformation and the deformation changes with the pressure difference, the threshold of capacitance change can be increased by changing the pressure difference without increasing the response sensitivity when testing capacitance change. This avoids interference from factors such as electromagnetic interference and assembly deviation when measuring capacitance change, thereby improving the stability and reliability of the refrigerator's air pressure switch in controlling the door opening.

[0024] This application also provides the following technical solutions:

[0025] A refrigerator includes a cabinet, a refrigerator door, and a refrigerator pressure switch as described in any of the above embodiments, disposed on the cabinet.

[0026] In one embodiment, the cabinet includes a shell, an inner liner, and an insulation layer. The inner liner encloses a low-temperature storage compartment. The shell surrounds the outer side of the inner liner, and the insulation layer is disposed between the shell and the inner liner. The base is located on the side of the insulation layer away from the inner liner, and the button faces the refrigerator door.

[0027] Understandably, by placing the base on the side of the insulation layer away from the inner liner, the gas inside the base can be further prevented from being affected by the low-temperature gas inside the refrigerator, thus ensuring that the gas pressed into the pressure switch assembly is at room temperature and basically the same as the gas temperature of the external environment, so that condensation will not form on the pressure switch assembly.

[0028] Compared to existing technologies, the refrigerator pressure switch utilizes a pressure transmission assembly comprising a base and a button. The base secures the pressure transmission assembly, and the button, which is confined to the base and retractable relative to it, abuts against the refrigerator door. When the refrigerator door shifts, the button retracts to the base, forcing gas from the chamber into the pressure switch assembly. This causes a change in the internal pressure of the pressure switch assembly. When the pressure change reaches a preset value, the refrigerator door is opened. Because the gas in the chamber of the pressure transmission assembly is not cold, there is no temperature difference between the two sides of the pressure switch assembly after it is pressed in, thus preventing condensation. This effectively avoids problems such as short circuits, device corrosion, or decreased sensitivity caused by condensation adhering to the pressure detection element. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0043] Please see Figures 1 to 5 This application provides a refrigerator pressure switch 100, which is installed on the body 201 of the refrigerator 200 and is used to control the automatic opening of the refrigerator door 202.

[0044] Specifically, the refrigerator pressure switch 100 includes a pressure switch assembly 10 and a pressure transmission assembly 20. The pressure switch assembly 10 is disposed on the cabinet 201. The pressure transmission assembly 20 includes a base 21 and a button 22. The base 21 is installed on the cabinet 201. The button 22 is located on the base 21 and is sealed to the base 21. The end of the button 22 away from the base 21 is attached to the refrigerator door 202. The button 22 and the base 21 enclose a chamber 23, and the chamber 23 is connected to the pressure switch assembly 10. The button 22 can retract the base 21 in response to the displacement of the refrigerator door 202, and the gas in the chamber 23 is forced into the pressure switch assembly 10, causing a change in the gas pressure inside the pressure switch assembly 10. The pressure switch assembly 10 controls the refrigerator door 202 to open in response to the change in gas pressure.

[0045] In existing technologies, the connection between the gas pressure switch assembly and the refrigerator's interior not only easily leads to condensation but also results in high environmental dependence and unstable sensitivity. Since its detection sensitivity depends on the establishment of a pressure difference between the inside and outside of the refrigerator, this pressure difference is affected by various factors such as the sealing of the door seal, the force and speed at which the user presses the door panel, and the placement of items inside the refrigerator. This leads to inconsistent triggering conditions and a high risk of false triggering or failure to trigger. Furthermore, there are hygiene and contamination risks. Introducing air from inside the refrigerator (which may contain food odors, microorganisms, etc.) into the mechanical switch structure poses potential hygiene problems and a risk of cross-contamination. This application utilizes a pressure transmission assembly 20 comprising a base 21 and a button 22. The base 21 secures the pressure transmission assembly 20, and the button 22, which is confined to the base 21 and retractable relative to it, abuts against the refrigerator door 202. When the user presses the refrigerator door 202, causing it to shift, the button 22 retracts into the base 21, forcing gas from the chamber 23 into the pressure switch assembly 10. This causes a change in the internal pressure of the pressure switch assembly 10. When the pressure change reaches a preset value, the refrigerator door 202 is opened. Since the gas in the chamber 23 of the pressure transmission assembly 20 is not at a low temperature, there is no temperature difference between the two sides of the pressure switch assembly 10 after it is pressed in. Therefore, condensation does not occur, effectively preventing condensation from adhering to the pressure detection element and causing problems such as short circuits, device corrosion, or decreased sensitivity. Furthermore, since the pressure switch assembly 10 is connected to the pressure transmission assembly 20 and is affected by the pressure transmission assembly 20 to form pressure changes, it does not depend on the environment of the refrigerator 200, can ensure the stability of pressure changes, and does not have hygiene problems.

[0046] like Figure 1 As shown, the refrigerator pressure switch 100 is installed on the frame of the cabinet 201, and the button 22 is in close contact with the inside of the refrigerator door 202 or has a very small gap 242, so that the button 22 can extend and retract relative to the base 21 in response to the displacement of the refrigerator door 202.

[0047] like Figure 5 As shown, the pneumatic switch assembly 10 includes a movable electrode 11, a fixed electrode 12, and a signal output component 13. The movable electrode 11 and the fixed electrode 12 are arranged at a distance from each other, and the signal output component 13 is electrically connected to the fixed electrode 12. The movable electrode 11 responds to changes in air pressure and moves closer to the fixed electrode 12. When the distance between them reaches a preset value, the signal output component 13 outputs an electrical signal to control the refrigerator door 202 to open. Here, the signal output component 13 can be implemented in various forms, including but not limited to mechanical contact switches, capacitive detection structures, and circuit boards integrating sensing and processing circuits, to convert changes in air pressure into trigger signals that can be recognized by the control system. Specific structures are common in the prior art and will not be described in detail here.

[0048] In one embodiment, the pneumatic switch assembly 10 includes a housing and an elastic seal 14. The elastic seal 14 is sealed to the housing and encloses a pneumatic chamber, which is connected to the chamber 23. A movable electrode 11 is disposed on the side of the elastic seal 14 away from the pneumatic chamber. The elastic seal 14 deforms in response to changes in pneumatic pressure, which can move the movable electrode 11 closer to the fixed electrode 12. By providing the elastic seal 14 and placing the movable electrode 11 on it, the elastic seal can better respond to changes in pneumatic pressure. Since the elastic seal 14 is easily deformable, and its deformation changes with the pressure difference, the threshold for capacitance change can be increased by changing the pressure difference without increasing the response sensitivity when testing capacitance change. This avoids interference from electromagnetic interference, assembly deviations, and other factors when measuring capacitance change, thereby improving the stability and reliability of the refrigerator pneumatic switch 100 in controlling the door opening. Here, the elastic seal 14 can be configured as a silicone sheet, rubber sheet, or other elastic sealing structure.

[0049] like Figure 1 and Figure 2 As shown, the base 21 is installed on the body 201 of the refrigerator 200, and the button 22 is installed on the end of the base 21 near the refrigerator door 202. The end of the base 21 away from the button 22 has a side wall 211, and a connecting hole 212 is provided on the side wall 211. The connecting hole 212 is connected to the air pressure chamber through the pipe 30.

[0050] Furthermore, the effective working area of ​​button 22 ( The design is more effective than the elastic seal 14 in the pneumatic switch in terms of its working area. The force exerted on button 22 is small. The pressure generated () The force is transmitted undamaged to the resilient seal 14. At this time, the force experienced by the resilient seal 14... .because ,so This amplifies the effect, allowing a larger force to drive the elastic seal 14 to be obtained with a smaller pressing force. When the pressing action occurs, the gas is compressed, agitating the elastic seal 14, thereby causing the elastic seal 14 to displace.

[0051] like Figure 4As shown, the pressure transmission assembly 20 also includes a guide member 24, which is disposed within the chamber 23 and fixedly connected to the base 21. The button 22 is sleeved on the outside of the guide member 24 and can move along the guide member 24. By providing the guide member 24, the button 22 can be guided when it retracts into the base 21. When the button 22 extends or retracts relative to the base 21, it can move along the guide member 24, thus improving the stability of the extension and retraction of the button 22.

[0052] Furthermore, the guide member 24 is configured as a hollow guide post 241, which is fixed to the side wall 211 and located on the outer periphery of the connecting hole 212, forming a gap 242 between the hollow guide post 241 and the button 22; wherein, the connecting hole 212 is connected to the pressure transmission assembly 20 through the pipe 30. It should be explained that the gap 242 can be achieved by providing grooves at intervals along the circumference on the inner wall of the button 22 near the hollow guide post 241 or by providing grooves at intervals along the circumference on the outer wall of the hollow guide post 241 near the button 22.

[0053] In one embodiment, the pressure transmission assembly 20 further includes an elastic element 25, which is sleeved on the hollow guide post 241, with one end abutting against the side wall 211 and the other end abutting against the button 22. When the button 22 retracts into the base 21, the elastic element 25 is compressed and can apply a force to the button 22 to reset it. When the hand is released, the force applied to the refrigerator door 202 disappears, the button 22 of the pressure transmission assembly 20 is reset under the action of the elastic element 25, the volume of the chamber 23 is restored, a negative pressure is generated inside, and air is drawn back from the side of the pressure switch assembly 10 through the pipe 30. The refrigerator pressure switch 100 returns to its initial state, that is, the elastic element 25 keeps the button 22 in the extended state.

[0054] In this embodiment, the elastic element 25 is configured as a spring.

[0055] In one embodiment, the pressure transmission assembly 20 further includes a seal 26 disposed between the button 22 and the base 21, thereby sealing the button 22 and the base 21. Here, the seal 26 can be a silicone sleeve, a sealing ring, or a bellows.

[0056] In this embodiment, a closed annular groove 261 is provided around the outer peripheral surface of the button 22 in the circumferential direction. The sealing member 26 is configured as an O-ring. The O-ring is sleeved on the button 22 and partially located in the annular groove 261. The button 22 abuts against and seals the base 21 in the circumferential direction through the O-ring.

[0057] This application also provides the following technical solutions:

[0058] like Figure 1As shown, a refrigerator 200 includes a cabinet 201, a refrigerator door 202, and a refrigerator pressure switch 100 as described in any of the above embodiments disposed on the cabinet 201.

[0059] In one embodiment, the cabinet 201 includes a shell 203, an inner liner 204, and an insulation layer 205. The inner liner 204 encloses a low-temperature storage compartment 206. The shell 203 surrounds the outer side of the inner liner 204, and the insulation layer 205 is provided between the shell 203 and the inner liner 204. The base 21 is located on the side of the insulation layer 205 away from the inner liner 204, and the button 22 faces the refrigerator door 202. Thus, by placing the base 21 on the side of the insulation layer 205 away from the inner liner 204, the gas inside the base 21 can be further prevented from being affected by the low-temperature gas inside the refrigerator 200, thereby ensuring that the gas pressed into the pressure switch assembly 10 is at room temperature, essentially the same temperature as the gas in the external environment, preventing condensation from forming on the pressure switch assembly 10.

[0060] The smart appliance containing the refrigerator pressure switch 100 has a smart voice control module. The smart voice control module includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the refrigerator pressure switch 100 to perform corresponding operations, thereby realizing the intelligent control of the refrigerator pressure switch 100 and improving the user experience of using the smart appliance.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
