Description

Technical Field

[0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine stop switch module, a control panel seat and a washing machine. Background Art

[0002] At present, when the washing machines on the market start to dehydrate, if the clothes are seriously overloaded and the inner barrel rotates seriously eccentrically, a large parallel amplitude will be generated, and the outer barrel will hit the washing machine body. In serious cases, the washing machine will shift. Therefore, when the washing machine starts to dehydrate, if the clothes are seriously overloaded, the outer barrel will hit the washing machine body. In order to prevent the outer barrel from hitting the washing machine body, a stop switch module is installed under the control plate of the washing machine. The stop switch module of a traditional washing machine generally includes a control rod module and a stop switch. When the outer barrel rotates with a large eccentricity, the outer barrel will hit the control rod module, and the action of the control rod module will cause the stop switch to disconnect, and the washing machine will stop running.

[0003] The trigger end of the upper part of the existing control rod module directly or indirectly contacts the contact of the stop switch, and the lower end cooperates with the upper end of the outer barrel. In order to facilitate triggering, the contact of the stop switch is set on the bottom wall of the stop switch. This design causes the control rod module to be installed in the rear space with a larger height of the control disc seat when it is installed on the control disc seat. This is because if the installation height of the control rod module in the control disc seat is reduced, when the washing machine dehydrates the washing machine barrel, the displacement of the upper end of the washing machine outer barrel is small, but because the distance between the position where the control rod module is hit by the upper end of the outer barrel and the trigger end of the upper part of the control rod module is close, the control rod module will have a large displacement, resulting in a false alarm of hitting the barrel, which will eventually cause the washing machine to frequently stop dehydrating. Therefore, the existing washing machines all install the stop switch module in the rear space with a larger height of the washing machine control disc seat.

[0004] However, as the functions of the washing machine increase, such as the installation of an automatic detergent dispensing device, an ultraviolet sterilization module, or an ultrasonic module with auxiliary functions, the space behind the control panel seat needs to be occupied. Therefore, the space of the control panel seat must be reallocated, and the stop switch module must be installed in a space with a smaller height of the washing machine control panel seat. In addition, in order to reduce the overall height of the washing machine or improve the aesthetics of the washing machine, some manufacturers design the height of the control panel seat exposed at the upper end of the box to be lower, so that the top wall of the control panel seat is closer to the upper end of the outer barrel, which relatively reduces the installation height of the stop switch module. The above improvements will cause frequent dehydration pauses during the operation of the washing machine, seriously affecting the normal operation of the washing machine.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing machine stop switch module that can be installed in a space with a relatively small height of a washing machine control panel seat.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a washing machine stop switch module, including a stop switch and a control rod module, a contact for connecting or disconnecting the stop switch is provided on the bottom wall of the stop switch, and the control rod module includes a trigger end for triggering the stop switch, and the trigger end is higher than the horizontal plane where the contact is located.

[0008] By setting the trigger end higher than the horizontal plane where the contact is located, the control rod module is moved upward relative to the stop switch, so that the total height of the stop switch module is reduced. The stop switch module can be installed in a space with a smaller height of the washing machine control plate seat. The problem of the stop switch module being too sensitive due to the installation position and the washing machine frequently and unnecessarily pausing the dehydration will not occur, and it is also convenient to reallocate the space in the washing machine control plate seat.

[0009] Furthermore, the stop switch module also includes a connecting member for transmitting the action of the trigger end to the contact.

[0010] Further, one end of the connecting member is connected to the stop switch, the connecting member abuts against the contact, and the other end of the connecting member abuts against the trigger end.

[0011] Furthermore, one end of the connecting member is connected to the trigger end, and the other end of the connecting member is used to contact the contact point.

[0012] By providing a connecting piece on the stop switch module, the control rod module can be moved upward relative to the stop switch, and the total length of the stop switch module is reduced. The stop switch module can be installed in a space with a smaller height of the washing machine control panel seat, which not only ensures the versatility of the module but also maximizes the use of the space of the washing machine control panel seat.

[0013] Furthermore, the connecting piece is integrally connected to the trigger end or is detachably connected to the trigger end.

[0014] Furthermore, the connecting member is an arc-shaped structure formed by bending and extending from one end close to the stop switch to the other end.

[0015] Further, the connecting member includes a first connecting portion and a second connecting portion, the first connecting portion is connected to the second connecting portion and forms an angle;

[0016] Preferably, the angle is ≥90°.

[0017] Furthermore, the connecting member further comprises a third connecting portion, and the third connecting portion is connected to the second connecting portion; the first connecting portion, the second connecting portion and the third connecting portion are flat plates or curved plates.

[0018] The present invention also provides a washing machine control panel seat having any of the above-mentioned washing machine stop switch modules, the washing machine control panel seat comprising a control panel seat top wall, a base for installing the stop switch module arranged on the inner side of the top wall of the control panel seat, the stop switch module being installed on the base, and the trigger end of the control rod module being located between the contact of the stop switch and the top wall of the control panel seat.

[0019] The present invention further provides a washing machine having the above-mentioned washing machine control disc seat, wherein the control rod module can be installed in a space with a relatively small height of the washing machine control disc seat.

[0020] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0021] (1) By making the trigger end higher than the horizontal plane where the contact is located, the control rod module can be moved upward relative to the stop switch, thereby reducing the total height of the stop switch module. The stop switch module can be installed in a space with a relatively small height of the washing machine control panel seat, so that the position where the washing machine outer drum collides with the control rod module is lowered. The problem of the stop switch module being too sensitive due to the installation position and the washing machine frequently and unnecessarily pausing the dehydration process will not occur, and it is also convenient to reallocate the space in the washing machine control panel seat.

[0022] (2) By providing the connecting member, the action of the trigger end is transmitted to the contact, so that the control rod module moves upward relative to the stop switch. The stop switch module can be installed in a space with a relatively small height of the washing machine control panel seat. The connecting member has a simple structure, which not only ensures the versatility of the module, but also maximizes the use of the space of the control panel seat.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0035] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figures 1 to 7 As shown, a stop switch module for a washing machine according to the present invention comprises a stop switch 1 and a control rod module 2, wherein a contact 11 for connecting or disconnecting the stop switch 1 is arranged on the bottom wall of the stop switch 1, and the control rod module 2 comprises a trigger end 21 for triggering the stop switch 1, and the trigger end 21 is higher than the horizontal plane where the contact 11 is located.

[0038] By making the trigger end 21 higher than the horizontal plane where the contact 11 is located, the length of the relative part of the control rod module 2 and the stop switch 1 is increased, the installation position of the control rod module 2 can be raised, and the total height of the stop switch module can be reduced. The stop switch module can be installed in a space with a small height of the washing machine control panel seat, which overcomes the problem in the prior art that when the stop switch module is installed in a space with a small height of the washing machine control panel seat, the outer drum hits the upper part of the control rod module due to the lowered installation position of the control rod module in the washing machine, which will cause a large offset, making the stop switch module too sensitive, causing the washing machine to frequently and unnecessary suspension of dehydration. This arrangement allows the stop switch module to be installed in a space with a small height of the control panel seat, and is also convenient for reallocating the space in the washing machine control panel seat.

[0039] The trigger end 21 may be a bottom plate of the control rod module 2, and the bottom plate is disposed at one end of the control rod module 2 for triggering the stop switch 1. The trigger end 21 may also be a point or a rod on the control rod module 2 for triggering the contact 11. The contact 11 may also be disposed on a bottom wall of the stop switch 1 or at the connection between two bottom walls, and the contact 11 at least partially protrudes from the bottom wall of the stop switch 1.

[0040] The stop switch module further includes a connector 3, which is used to transfer the action of the trigger end 21 to the contact 11. In this embodiment, the contact 11 of the stop switch 1 is directly connected or indirectly abutted with the trigger end 21 of the control rod module 2 through the connector 3, and the connector 3 transfers the abutting action of the trigger end 21 to the contact 11, and the contact 11 is connected to the stop switch 1, and the stop switch 1 is in a normally closed state. When the control rod module 2 is deflected by an external force, the trigger end 21 moves away from the contact 11, and the contact 11 is no longer subjected to the force of the trigger end 21, and the contact 11 disconnects the stop switch 1, and the washing machine stops dehydrating.

[0041] like Figure 1 As shown, as a preferred embodiment, one end of the connector 3 is connected to the stop switch 1, the connector 3 abuts against the contact 11, and the other end of the connector 3 abuts against the trigger end 21. When the trigger end 21 abuts against the connector 3, the connector 3 abuts against the contact 11 to connect with the stop switch 1, and the washing machine can be dehydrated at this time; when the outer barrel of the washing machine is overloaded, the control rod module 2 is offset away from the connector 3 by the impact force of the outer barrel, and the connector 3 is no longer pressed against the contact by external force, and the connector 3 is away from the contact 11, so that the stop switch 1 is disconnected and the washing machine stops dehydrating.

[0042] The connecting member 3 may be an arc-shaped structure bent and extended from one end close to the stop switch 1 to the other end. One end of the connecting member 3 is connected to the stop switch 1 , and the upward arc-shaped portion of the other end is arranged above the trigger end 21 and conflicts with the trigger end 21 .

[0043] like Figure 2 and Figure 5 As shown, the connecting member 3 includes a first connecting portion 31 and a second connecting portion 32, wherein the first connecting portion 31 is connected to the second connecting portion 32 and forms an angle. One end of the first connecting portion 31 is connected to the stop switch 1, and the first connecting portion 31 or the second connecting portion 32 contacts the contact 11. The second connecting portion 32 is tilted upward and at least partially disposed above the trigger end 21, contacting the trigger end 21. Preferably, the angle between the first connecting portion 31 and the second connecting portion 32 is ≥90°.

[0044] Further, the connector 3 further includes a third connecting portion 33, and the third connecting portion 33 is connected to the second connecting portion 32. One end of the first connecting portion 31 is connected to the stop switch 1, the first connecting portion 31 or the second connecting portion 32 abuts against the contact 11, and the third connecting portion 33 is at least partially disposed above the trigger end 21 and abuts against the trigger end 21.

[0045] Preferably, the connector further includes a fourth connection part 34, one end of which is connected to the stop switch 1, and the other end of which is connected to the first connection part 31, and the first connection part 31 contacts the contact. The third connection part 33 is parallel to the first connection part 31, and the second connection part 32 is connected to the third connection part 33 at a right angle. The height of the second connection part 32 is greater than the height of the first connection part 31. When the trigger end 21 of the control rod module 2 contacts the third connection part 33, the first connection part 31 contacts the contact 11, the stop switch 1 is connected, and the washing machine can be dehydrated; when the outer barrel of the washing machine is overloaded, the control rod module 2 is offset away from the third connection part 33 by the impact force of the outer barrel, so that the first connection part 31 is away from the contact, the stop switch 1 is disconnected, and the washing machine stops dehydrating.

[0046] The first connecting portion 31, the second connecting portion 32, the third connecting portion 33 and the fourth connecting portion 34 are flat plates or curved plates. The connecting member 3 can be a bent panel formed by combining a plurality of curved plates and a plurality of flat plates, or a bent panel formed by connecting a plurality of flat plates. The connecting member is preferably a metal spring.

[0047] like Figure 3 As shown, as an alternative embodiment, one end of the connecting member 3 described in this embodiment is connected to one end of the trigger end 21, and the other end of the connecting member 3 is used to conflict with the contact 11. The connecting member 3 can be a flat plate, one end of the connecting member 3 is connected to the trigger end 21, and the other end is tilted downward and conflicts with the contact 11 to connect with the stop switch. The connecting member 3 can also be an arc-shaped structure bent and extended from one end close to the stop switch 1 to the other end, one end of the connecting member 3 is connected to the trigger end 21, and the downward arc portion of the other end is arranged below the contact and conflicts with the contact 11.

[0048] Furthermore, the connector 3 is integrally connected to the trigger end 21 or detachably connected. The connector 3 and the trigger end 21 can be sleeved, and only the connector 3 needs to be sleeved on the trigger end 21 of the control rod module 2 of the existing stop switch module, so that it can be installed in a space with a small height of the washing machine control panel seat, and the universality of the module is ensured. The connector 3 can be an arc-shaped member.

[0049] like Figure 4 and Figure 5As shown, the connecting member 3 includes a first connecting portion 31 and a second connecting portion 32, and the first connecting portion 31 is connected to the second connecting portion 32 and forms an angle. The second connecting portion 32 is connected to the trigger end 21, and the first connecting portion 31 is at least partially arranged below the contact 11 and contacts the contact 11. When the first connecting portion 31 contacts the contact 11, the stop switch 1 is connected, and the washing machine can be dehydrated. When the outer barrel of the washing machine is overloaded, the control rod module 2 is offset by the impact force of the outer barrel, driving the first connecting portion 31 away from the contact 11, disconnecting the stop switch 1, and the washing machine stops dehydrating. Preferably, the angle between the first connecting portion 31 and the second connecting portion 32 is ≥90°.

[0050] Furthermore, the connecting member 3 further includes a third connecting portion 33 , and the third connecting portion 33 is connected to the second connecting portion 32 .

[0051] The first connecting part, the second connecting part and the third connecting part are flat plates or curved plates. The connecting member can be a bent panel formed by connecting a plurality of curved plates and a plurality of flat plates, or a bent panel formed by connecting a plurality of flat plates.

[0052] like Figure 6 and 7 As shown, this embodiment also provides a washing machine control panel seat 4, which includes a washing machine stop switch module, a control panel seat top wall 41, and a base 42 for installing the stop switch module arranged on the inner side of the control panel seat top wall 41, the stop switch module is installed on the base 42, and the trigger end 21 of the control lever module 2 is located between the contact 11 of the stop switch 1 and the control panel seat top wall 41.

[0053] Preferably, the control lever module is hinged on the base 42, the trigger end 21 is the bottom plate of the control lever module 2, the bottom plate is arranged at one end of the control lever module 2 for triggering the stop switch 1, and the bottom plate of the control lever module 2 is located between the contact 11 of the stop switch 1 and the top wall 41 of the control panel seat. The contact 11 is arranged on a bottom wall of the stop switch 1, and the contact 11 at least partially protrudes from the bottom wall of the stop switch 1.

[0054] By setting the trigger end 21 of the control lever module 2 between the contact 11 of the stop switch 1 and the top wall 41 of the control panel seat, the installation height of the control lever module 2 installed on the top wall 41 of the control panel seat is reduced, and the height of the stop switch module installed on the top wall 41 of the control panel seat is reduced. The stop switch module can be installed in a space with a smaller height of the control panel seat 4, thereby maximizing the use of the space of the washing machine control panel seat 4.

[0055] The stop switch module also includes a connector 3, which is used to transfer the action of the trigger end 21 to the contact 11. The contact 11 of the stop switch 1 is directly connected or indirectly contacted with the trigger end 21 of the control rod module 2 through the connector 3. The connector 3 transfers the contact action of the trigger end 21 to the contact 11. The contact 11 is connected to the stop switch 1, and the stop switch 1 is in a normally closed state. When the outer barrel of the washing machine is overloaded, the control rod module 2 is subjected to the impact force of the outer barrel, and rotates along the hinge axis of the control rod module 2 to produce an offset. The connector 3 is no longer subjected to the force to press the contact 11, and the connector 3 moves away from the contact 11, so that the stop switch 1 is disconnected, and the washing machine stops dehydrating. The problem of the stop switch module being too sensitive due to the installation position, resulting in frequent and unnecessary dehydration pauses of the washing machine, will not occur.

[0056] The present embodiment also provides a washing machine, which includes a control panel seat 4. The washing machine is installed with the control panel seat 4, and the control panel seat 4 includes a stop switch module. The stop switch module can be installed in a space with a relatively small height of the control panel seat 4, and the problem of the stop switch module being too sensitive due to the installation position problem and the washing machine frequently and unnecessarily pausing the dehydration will not occur.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
