Description

Technical Field

[0001] The utility model relates to the field of electrical appliance control, in particular to a push switch and a refrigerator comprising the push switch. Background Art

[0002] With the development of household refrigerators, users have higher and higher requirements for the functions or usage of household refrigerators. Among them, for fully embedded refrigerators, usually no handle is set on the outside. In order to realize the automatic opening and closing of the refrigerator door, a switch needs to be set on the refrigerator to realize the control of the refrigerator, for example, a switch is set on the refrigerator door to control the automatic opening and closing of the refrigerator door.

[0003] At present, the common practice is to set a touch button locally on the refrigerator door. When a finger touches it, the sensor circuit board feeds back the door opening signal to the main control board, and the main control board controls the door opening motor to push the door open. However, this setting method can only open the door at a specific touch position or press position, and the flexibility of use is poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect of poor flexibility in use caused by the specific touch position or pressing position of the push switch for automatically opening the refrigerator door in the prior art, and to provide a push switch and a refrigerator containing the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] The utility model discloses a push switch, which is characterized in that the push switch comprises a shell, a conductive sheet and a switch bracket, the shell has a hollow cavity, the switch bracket is arranged at the end of one end of the shell, a plurality of conductive contact sheets are arranged on the switch bracket, and the plurality of conductive contact sheets are sequentially away from the center of the conductive sheet;

[0007] The conductive sheet is arranged below the switch bracket in the housing, and when the conductive sheet is deformed, it contacts at least two conductive contact sheets on the switch bracket.

[0008] In this solution, multiple conductive contact pieces are arranged in sequence away from the center of the conductive piece, and at least two conductive contact pieces can be connected by using a deformable conductive piece, and the number of conductive contact pieces that are connected increases with the pressing force. Among them, the hollow structure of the shell can deform the conductive piece through the change of air pressure when the user presses. Different pressing forces of the user will cause different deformation amounts of the deformable conductive piece, so that the number of conductive contact pieces that are connected is different, so that different trigger positions can be triggered to achieve the opening of the door body. In other words, the push switch can be widely applicable to the door opening force requirements of a variety of users or even the entire family, and can achieve the smooth opening of the door body and avoid the problem of low door opening flexibility. In addition, the push switch can also serve as a child lock. For example, when the user sets that children cannot open the door body, the wire transmission signal for low-force door opening can be selectively turned off, and the door body can only be triggered to open when the door pressing force is large, thereby avoiding the unexpected door body opening by mistake.

[0009] Preferably, the push switch further comprises a first sealing ring and a gasket, the gasket is arranged between the switch bracket and the conductive sheet, and the first sealing ring is closely arranged on a side of the conductive sheet away from the switch bracket.

[0010] In this solution, the gasket is arranged between the switch bracket and the conductive sheet, and the gasket can limit the edge position of the conductive sheet.

[0011] Preferably, when the conductive sheet is not deformed, the gasket allows a gap to exist between the conductive sheet and the conductive contact sheet.

[0012] In this solution, when the conductive sheet is not deformed, the gasket leaves a gap between the conductive sheet and the conductive contact sheet. When the conductive sheet is not deformed, the conductive contact sheet is not conducting, which is beneficial to ensure the reliability of the push switch.

[0013] Preferably, a step portion is circumferentially arranged inside the housing, and the first sealing ring is arranged on a surface of the step portion on a side close to the switch bracket.

[0014] In this solution, a step portion is provided in the circumferential direction of the housing, and the step portion is used to provide a first sealing ring to limit the first sealing ring in the axial direction. The first sealing ring does not move in the axial direction, and the sealing effect of the first sealing ring can be improved.

[0015] Preferably, the push switch further includes a gas channel, the housing and a portion of the conductive sheet away from the switch bracket together form a closed cavity, and one side of the gas channel is connected to the closed cavity.

[0016] In this solution, the portion below the conductive sheet in the shell is used as a closed cavity, and a gas channel is provided, leading to the closed cavity from the outside. By using this solution, the air cavity of the push switch can be extended to different directions through the gas channel, which makes it easy to hide the shell inside the refrigerator and hide the switch shell, which is more beautiful.

[0017] Preferably, the push switch further includes a second sealing ring, and a groove is provided outside the gas channel for accommodating the second sealing ring.

[0018] In the present solution, a groove is provided outside the gas channel, and the groove is used to place a second sealing ring. The second sealing ring can be used to seal the hole for setting the button to prevent external gas from entering or leaving the closed space on the side of the conductive sheet away from the switch bracket. It is also beneficial to ensure that when the switch needs to be triggered, the air pressure change can reliably deform the conductive sheet, so that the switch can be triggered more sensitively.

[0019] Preferably, the push switch includes a signal output end, at least one of the multiple conductive contact pieces is a common end of the push switch, and the remaining conductive contact pieces are trigger ends of the push switch. When the conductive piece is deformed, it connects the common end and at least one of the trigger ends, and sends a signal to the signal output end after connection.

[0020] In this solution, at least one conductive contact piece is used as a common terminal, and the other conductive contact pieces are used as trigger terminals. After the conductive piece conducts the common terminal and at least one trigger terminal, a signal can be sent to the signal output terminal, and the signal output terminal outputs a door opening signal according to the number of conduction. In addition, the use of this setting makes it simple to implement the method of outputting the door opening signal according to a variety of pressing forces, which is conducive to simplifying the structure of the push switch and also conducive to reducing the cost of the push switch.

[0021] Preferably, the push switch comprises a wire, and a plurality of the wires are led out from a plurality of the conductive contact pieces.

[0022] Preferably, the switch bracket includes a pressure relief hole, and the pressure relief hole passes through the upper and lower surfaces of the switch bracket.

[0023] In this solution, a through hole penetrating the upper and lower surfaces of the switch bracket is provided on the switch bracket as a pressure relief hole, which is used to keep the air pressure above the conductive sheet constant so that the switch can be triggered more sensitively.

[0024] The utility model also provides a refrigerator, which is characterized in that the refrigerator comprises a box body, a door body and a push switch, the box body and the door body constitute a storage space, one side of the push switch is connected to the storage space, and the other side is connected to the outside atmosphere.

[0025] In this solution, a push switch is set on the box body, and various functions of the refrigerator can be controlled by the push switch, such as automatic door opening and closing, adjusting the refrigerator temperature, etc. Among them, when the push switch is used for automatic door opening and closing, its function or effect can be reflected in the following two aspects: (1) Since different users have different pressing forces on the door body, there may be a phenomenon that, for example, a girl or a child presses the door with a small force and cannot trigger the door to open. By using this push switch, it can be widely applicable to the door opening force requirements of multiple users or even the entire family, and can realize the smooth opening of the door body and avoid the problem of low door opening flexibility; (2) The push switch can also serve as a child lock. For example, when the user sets that children cannot open the door body, the wire transmission signal for low-force door opening can be selectively turned off, and the door body can only be triggered to open when the door is pressed with a large force, thereby avoiding the unexpected door body opening by mistake.

[0026] The positive and progressive effect of the utility model is that: a plurality of conductive contact pieces are arranged in sequence away from the center of the conductive piece, and at least two conductive contact pieces can be connected by using a deformable conductive piece, and the number of conductive conductive contact pieces increases with the pressing force. Among them, the hollow structure of the shell can deform the conductive piece by the change of air pressure when the user presses, and the different pressing forces of the user will cause different deformation amounts of the deformable conductive piece, so that the number of conductive conductive contact pieces is different, so that different trigger positions can be triggered to achieve the opening of the door body. In other words, the push switch can be widely applicable to the door opening force requirements of a variety of users or even the entire family, and can achieve the smooth opening of the door body and avoid the problem of low door opening flexibility. In addition, the push switch can also serve as a child lock. For example, when the user sets that children cannot open the door body, the wire transmission signal for low-force door opening can be selectively turned off, and the door body can only be triggered to open when the door pressing force is large, thereby avoiding the unexpected door body opening by mistake.

[0031] Explanation of reference numerals: housing 1 , first sealing ring 2 , conductive sheet 3 , gasket 4 , switch bracket 5 , second sealing ring 6 , conductive contact sheet 7 , wire 8 , pressure relief hole 9 , step portion 10 , gas channel 11 . DETAILED DESCRIPTION

[0032] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0033] like Figure 1-2 As shown, the push switch includes a housing 1, a conductive sheet 3 and a switch bracket 5. The housing 1 has a hollow cavity. The switch bracket 5 is arranged at the end of one end of the housing 1. A plurality of conductive contact sheets 7 are arranged on the switch bracket 5. The plurality of conductive contact sheets 7 are sequentially away from the center of the conductive sheet 3.

[0034] In the housing 1 , a conductive sheet 3 is disposed below the switch bracket 5 . When the conductive sheet 3 is deformed, it contacts at least two conductive contact sheets 7 on the switch bracket 5 .

[0035] In this embodiment, the conductive contact piece 7 is annular, and multiple conductive contact pieces 7 are successively away from the center of the conductive piece 3. The use of the easily deformable conductive piece 3 can conduct at least two conductive contact pieces 7, and the number of conductive conductive contact pieces 7 increases with the pressing force. Among them, the hollow structure of the shell 1 can deform the conductive piece 3 through the change of air pressure when the user presses. Different pressing forces of the user will cause different deformation amounts of the easily deformable conductive piece 3, so that the number of conductive conductive contact pieces 7 is different, so that different trigger positions can be triggered to achieve the opening of the door body. In other words, the push switch can be widely applicable to the door opening force requirements of multiple users or even the entire family, and can achieve the smooth opening of the door body and avoid the problem of low door opening flexibility. In addition, the push switch can also serve as a child lock. For example, when the user sets that children cannot open the door body, the wire transmission signal for low-force door opening can be selectively turned off, and the door body can only be triggered to open when the door pressing force is large, thereby avoiding the unexpected door body opening by mistake.

[0036] In other alternative embodiments, if multiple conductive contacts 7 can be insulated from each other and multiple conductive contacts 7 can be connected to the conductive sheet 3, it is also possible not to use nested annular conductive contacts 7. For example, multiple sheet-shaped conductive contacts 7 can be stacked in sequence from small to large, where the largest conductive contact 7 is fitted on the switch bracket 5, and an insulating layer is provided on the side of all conductive contacts 7 close to the switch bracket 5 to insulate them from the adjacent conductive sheets 3.

[0037] like Figure 1-2 As shown, the push switch further includes a first sealing ring 2 and a gasket 4. The gasket 4 is arranged between the switch bracket 5 and the conductive sheet 3. The first sealing ring 2 is arranged on a side of the conductive sheet 3 away from the switch bracket 5.

[0038] In this embodiment, the first sealing ring 2 is provided to avoid air leakage when the housing 1 is pressed away from the switch bracket 5, and the conductive sheet 3 is more easily deformed by atmospheric pressure. The gasket 4 is provided between the switch bracket 5 and the conductive sheet 3, and the gasket 4 can limit the edge position of the conductive sheet 3.

[0039] like Figure 1 As shown, in this embodiment, the gasket 4 is preferably set as a sheet-shaped annular structure. When the conductive sheet 3 is not deformed, the gasket 4 leaves a gap between the conductive sheet 3 and the conductive contact sheet 7, and the conductive sheet 3 does not conduct the conductive contact sheet when it is not deformed. The first sealing ring 2 is a circular ring body and has elasticity, so that when the conductive sheet 3 protrudes toward the conductive contact sheet 7, its edge can be deformed away from the conductive contact sheet 7 accordingly. The use of this solution is conducive to the deformation of the conductive sheet 3.

[0040] In other alternative embodiments, if the conductive sheet 3 can be prevented from contacting the conductive contact sheet 7 when it is not deformed, the shape of the first sealing ring 2 may be changed, the first sealing ring 2 may not be provided, or the airtightness may be ensured by other means, such as directly providing a slot or buckle on the housing 1 to limit the edge of the conductive sheet 3.

[0041] like Figure 2 As shown, a step portion 10 is circumferentially arranged inside the housing 1 , and the first sealing ring 2 is arranged on the surface of the step portion 10 on a side close to the switch bracket 5 .

[0042] In this embodiment, a step portion 10 is circumferentially arranged inside the housing 1, and the step portion 10 is used to arrange the first sealing ring 2 to limit the first sealing ring 2 in the axial direction. The step portion 10 is a solid structure away from the side of the switch bracket 5 to the bottom of the housing 1.

[0043] In other alternative embodiments, if the first sealing ring 2 and the conductive sheet 3 can be kept suspended in the housing 1, the step portion 10 may not be provided. For example, the first sealing ring 2 is fixedly provided inside the housing 1 to avoid the need for the step portion 10 to provide support.

[0044] like Figure 1-2 As shown, the push switch further includes a gas channel 11 , the housing 1 and a portion of the conductive sheet 3 away from the switch bracket 5 together form a closed cavity, and one side of the gas channel 11 is connected to the closed cavity.

[0045] In this embodiment, the portion below the conductive sheet 3 in the shell 1 is used as a closed cavity, and a gas channel 11 is provided, leading to the closed cavity from the outside. The gas channel 11 is perpendicular to the axis of the shell 1. By using this solution, the air cavity of the push switch can be extended to different directions through the gas channel 11, which makes it easy to hide the shell 1 inside the refrigerator and hide the switch shell, which is more beautiful.

[0046] In other alternative embodiments, as long as the gas channel 11 leads to the closed space below the conductive sheet 3, the setting position and direction of the gas channel 11 are not limited, and the gas channel 11 can be at any position connected to the closed space with the other end facing any direction.

[0047] like Figure 4As shown, the push switch includes a signal output terminal, one of the conductive contact pieces 7 is the common terminal of the push switch, and the remaining conductive contact pieces 7 are the trigger terminals of the push switch. The conductive sheet 3 connects the common terminal and at least one trigger terminal when deformed, and sends a signal to the signal output terminal after connection.

[0048] In this embodiment, one of the conductive contact pieces 7 serves as a common terminal, and the remaining conductive contact pieces 7 serve as trigger terminals. After the conductive sheet 3 conducts the common terminal and at least one trigger terminal, a signal can be sent to the signal output terminal, thereby realizing the output of a door opening signal by pressing the door.

[0049] The position of the public terminal is not specifically limited. In this embodiment, the conductive contact sheet closest to the conductive sheet 3 (i.e., the innermost side) is used as the common terminal. In other alternative embodiments, the position of the common terminal can be replaced, for example, the second conductive contact sheet 7 counted from the inside to the outside is set as the common terminal. It only needs to have a common terminal and more than one trigger terminal.

[0050] like Figure 3 As shown, the push switch includes a wire 8 , and a plurality of wires 8 are led out from a plurality of conductive contact pieces 7 .

[0051] In this embodiment, the wire 8 is led out from the conductive contact 7, and the signal of the conductive contact 7 is output to the signal output end. The signal output end communicates with the signal receiving device of the refrigerator (such as the main control board), thereby enabling the refrigerator door to be opened.

[0052] It should be noted that in other alternative implementations, a main control board can be separately configured for the push switch, that is, the main control board is used as a signal output terminal, and the main control board of the push switch is then communicatively connected with the main control board of the refrigerator.

[0053] like Figure 3 As shown, the switch bracket 5 includes a pressure relief hole 9, which passes through the upper and lower surfaces of the switch bracket 5, and there are no wires 8 and conductive contacts above and below the pressure relief hole 9.

[0054] In this embodiment, a through hole penetrating the upper and lower surfaces of the switch bracket 5 is provided on the switch bracket 5 as a pressure relief hole 9, and avoids the wire 8 and the conductive contact piece. There is a pair of pressure relief holes 9, which are symmetrically arranged on both sides of the wire 8 and the conductive contact piece. When the conductive sheet is deformed, the gas between the conductive sheet 3 and the switch bracket 5 can be discharged through the pressure relief hole, which is used to keep the air pressure in the space above the conductive sheet 3 unchanged, so that the switch can be triggered more sensitively.

[0055] As long as the arrangement of the pressure relief hole 9 does not affect the normal function of the conductive sheet 3 and the conductive contact sheet 7 , the location of the pressure relief hole 9 is not limited.

[0056] When the push switch of this embodiment is actually used, when the door or the box is pressed, the gas in the refrigerator compartment enclosed by the door and the box is compressed, and the compressed gas enters the shell 1 through the gas channel 11, exerting pressure on the conductive sheet 3, and the conductive sheet 3 is deformed under pressure. As the pressure increases from small to large, the conductive sheet 3 swells and deforms to a greater extent, and sequentially contacts with multiple conductive contact sheets 7 from the inside to the outside on the switch bracket 5. For example, there are 4 conductive contact sheets 7 on the switch bracket 5, the innermost conductive contact sheet 7 serves as the common end of the switch, and the three outer conductive contact sheets 7 serve as the trigger ends of the switch. There are 4 states during the deformation of the conductive sheet 3:

[0057] (1) When not pressed, there is no conductive contact piece 7 or only the innermost conductive contact piece 7 is in contact with the conductive piece 3, and the switch is not turned on;

[0058] (2) When the pressing force is small, the two innermost conductive contact pieces 7 contact the conductive piece 3, and the switch is turned on, which is the low gear;

[0059] (3) When the pressing force is large, the three innermost conductive contact pieces 7 contact the conductive piece 3, and the switch is turned on, which is the middle position;

[0060] (4) When the pressing force is the maximum, all the conductive contact pieces 7 are in contact with the conductive piece 3, and the switch is turned on, which is the high level.

[0061] When there are n conductive contacts 7, there are n connected states and n-1 gears. These n states can be used as n signals to input the main control board, so as to further distinguish the pressing force into n-1 gears to meet the pressing triggering scenarios of different users, and realize functions such as pressing to control the door opening motor action.

[0062] The present embodiment further provides a refrigerator, which includes a box body, a door body and a push switch, wherein the box body and the door body constitute a storage space, and one side of the push switch is connected to the storage space, and the other side is connected to the outside atmosphere.

[0063] In this embodiment, a push switch is arranged on the box body, and various functions of the refrigerator can be controlled by the push switch, such as automatic door opening and closing, adjusting the refrigerator temperature, etc. The upper surface of the switch bracket 5 of the push switch is open to the atmosphere, and the gas channel 11 is connected to the storage space of the refrigerator. The user can trigger the switch by pressing the surface of the door body. Among them, when the push switch is used for automatic door opening and closing, its function or effect can be reflected in the following two aspects: (1) Due to the different pressing forces of different users on the door body, there may be a phenomenon that, for example, a girl or a child presses the door with a small force and cannot trigger the door body to open. By using this push switch, it can be widely applicable to the door opening force requirements of various users or even the whole family, and can realize the smooth opening of the door body and avoid the problem of low door opening flexibility; (2) The push switch can also serve as a child lock. For example, when the user sets that children cannot open the door body, the wire transmission signal for low-force door opening can be selectively turned off, and the door body can only be triggered to open when the door pressing force is large, thereby avoiding the unexpected door body opening by mistake.

[0064] In another alternative embodiment, a gas channel 11 is provided in the push switch, and the setting position of the push switch relative to the box body can be:

[0065] (1) The push switch is arranged inside the box, the upper surface of the switch bracket 5 of the push switch is open to the atmosphere, and the gas channel 11 faces the inside of the box. There is no need to add a sealing member outside the gas channel 11, nor is there any need to specially design the shape of the gas channel 11;

[0066] (2) The push switch is set outside the box, and the shape of the gas channel 11 needs to be adjusted so that it can connect to the inside of the box. The adjustment method can be to set the gas channel 11 as a curved pipe, or to lengthen the pipe to extend into the pressing position. Correspondingly, the shape of the shell 1 should also be adjusted to match the shape of the gas channel 11. This setting method connects the sealed space and the pressing space inside the shell 1 by specially designing the shape of the gas channel 11, so that the setting form of the push switch body is more flexible.

[0067] When the push switch is set outside the box, the sealing problem needs to be considered. The connection between the gas channel 11 and the pressurized space needs to be sealed to prevent gas leakage and reduce the sensitivity of the switch. Figure 1 , Figure 2 As shown, by arranging the second sealing ring 6 outside the gas channel 11, adjusting the external shape of the gas channel 11, and arranging the limit groove to install the second sealing ring 6, a sealing effect can be achieved, thereby ensuring the pressing sensitivity of the switch. Alternatively, by taking advantage of the fact that a heat preservation foam layer is generally provided in the compartment of the refrigerator body, the gas channel 11 is inserted into the box body through the heat preservation foam layer, and the heat preservation foam layer can be used to squeeze and seal the gas channel 11, without the need for an external seal, and the structure is simpler.

The indicated directions are only used to simplify the description of the utility model, and are not used as specific directions for actual installation and use, and therefore are not used as limitations on the utility model.

The above-mentioned exemplified adjusted implementation methods all fall within the protection scope of the present invention and will not result in the loss of key technical effects.
