Description

Technical Field

[0001] The present invention belongs to the field of washing machines, and in particular, relates to an integrated device of a washing machine and a washing machine. Background Art

[0002] At present, all pulsator washing machines are equipped with a cover opening safety switch and a drum collision safety switch, which are generally installed in the pan base of the washing machine.

[0003] During the dehydration process of the washing machine, if the clothes are unbalanced, the drum will hit the control rod of the drum safety switch, triggering the contact of the drum safety switch to disconnect the drum safety switch, stopping the washing machine from rotating and correcting the deviation or unbalanced load.

[0004] When the user opens the door cover during the operation of the washing machine, the cover opening safety switch detects the signal of the door cover opening, and transmits the signal to the computer board, and the washing machine will alarm and stop running to protect the user's safety. Specifically, when the door cover is closed, the contact of the cover opening safety switch is triggered to connect the cover opening safety switch, and when the door cover is opened, the contact no longer presses the contact, so that the contact rebounds and the cover opening safety switch is disconnected, and the washing machine receives the signal of opening the door cover.

[0005] In the prior art, in order to save space in the washing machine, the cover opening safety switch and the barrel collision safety switch can be integrated together to form an integrated safety switch, which reduces the volume occupied by the structure, can save space in the washing machine, and is easy to install. However, the integrated safety switch includes two switches, and the structure volume is still large, which needs to be further optimized and reduced. In addition, the integrated safety switch has four wiring terminals, two of which are connected to the cover opening safety switch and two of which are connected to the barrel collision safety switch, and the number of terminal interfaces is large.

[0006] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0050] 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.

[0051] 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.

[0052] 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.

[0053] like Figures 1 to 9 As shown, the present invention provides an integrated device for a washing machine, which integrates a cover opening safety switch and a drum collision safety switch into one.

[0054] The integrated device comprises a mounting seat 1 , a safety switch 2 , a pressure rod 3 and a control rod 4 .

[0055] The safety switch 2 is mounted on the mounting base 1. The safety switch 2 comprises a first elastic sheet 21 and a second elastic sheet 22. The first elastic sheet 21 and the second elastic sheet 22 are in contact or separation with each other so that the safety switch 2 is connected or disconnected accordingly.

[0056] The pressure rod 3 is rotatably mounted on the mounting seat 1, and is used to provide a first force, pressing the first elastic sheet 21 to contact or disconnect the second elastic sheet 22, so that the safety switch 2 is connected or disconnected, and a cover opening signal can be generated to stop the washing program of the washing machine. In the washing machine, the door cover presses the pressure rod 3 so that the pressure rod 3 provides the first force.

[0057] The control rod 4 is rotatably mounted on the mounting seat 1, and is used to provide a second force, press the second spring sheet 22 to contact or disconnect the first spring sheet 21, connect or disconnect the safety switch 2, and generate a drum collision signal, so that the washing machine stops running the washing program to correct the deviation. In the washing machine, the outer drum hits the control rod 4, so that the control rod 4 provides the second force.

[0058] The cover-opening signal or the barrel-collision signal may be generated when the safety switch 2 is connected, and the cover-opening signal or the barrel-collision signal may be generated when the safety switch 2 is disconnected.

[0059] The safety switch 2 may be electrically connected to the washing program of the washing machine, and the cover-opening signal or the barrel-collision signal may be disconnected by the safety switch 2, so that the washing program of the washing machine is disconnected and the washing machine stops running; or the safety switch 2 may be electrically connected, so that the signal module is connected, and a cover-opening signal or a barrel-collision signal is sent to the washing machine, and the washing machine is controlled to stop running.

[0060] The integrated device of the present invention mounts the first spring piece 21, the second spring piece 22, the pressure rod 3 and the control rod 4 on the mounting base 1 to form an integrated structure. During the closing process of the door cover, the pressure rod 3 can be driven to press the first spring piece 21 to contact or separate with the second spring piece 22; when the washing machine drum hits the control rod 4, the second spring piece 22 can be pressed to contact or separate with the first spring piece 21. The first spring piece 21 and the second spring piece 22 cooperate with each other, and the safety switch 2 is connected after contact, and disconnected after no contact. The integrated device can be used as a safety switch for opening the cover or as a safety switch for hitting the drum. Two sets of safety switches are not required, only two wiring terminals are needed. The structure is simple, the space occupied is small, and the assembly is convenient.

[0061] The integrated device has two wiring terminals after integration, the number of parts is reduced, the number of connections with the washing machine is reduced, the structure is simplified, the production efficiency is high, and the space occupied is small.

[0062] like Figures 1 to 4 As shown, the first elastic sheet 21 is arranged at a distance from at least part of the second elastic sheet 22. The first output portion 33 of the pressure rod 3 is arranged opposite to the first elastic sheet 21, and is used to provide a first force to push the first elastic sheet 21 and the second elastic sheet 22 to contact and connect the safety switch 2. The safety switch 2 can be connected in series with the washing program of the washing machine. The connection of the safety switch 2 allows the washing machine to run the washing program normally.

[0063] The present invention arranges the first spring sheet 21 and at least a part of the second spring sheet 22 relatively spaced apart. When the door cover is closed and presses the pressure rod 3, the pressure rod 3 presses the first spring sheet 21 and connects the second spring sheet 22, so that the washing program of the washing machine is connected and the washing machine runs the washing program normally. When the door cover is opened, the pressure rod 3 is reset so that the first spring sheet 21 is no longer pressed, the first spring sheet 21 and the second spring sheet 22 are disconnected, so that the washing program of the washing machine is disconnected, and the washing machine stops running the washing program. Only the safety switch 2 is needed, and no other signal modules need to be added to cooperate with the washing machine. The structure is simple and the cost is low.

[0064] The second output portion 43 of the control rod 4 is arranged opposite to the second elastic sheet 22, and is used for providing a second force to push the second elastic sheet 22 away from the first elastic sheet 21 to disconnect the safety switch 2. The safety switch 2 can be connected in series with the washing program of the washing machine. When the safety switch 2 is disconnected, the washing program of the washing machine is electrically disconnected, thereby stopping the washing program.

[0065] When the outer tub is not unbalanced, the control rod 4 does not press the second elastic sheet 22 in the original position. When the outer tub is not unbalanced, when the door cover is closed, the pressure rod 3 presses the first elastic sheet 21 to move toward the second elastic sheet 22 to connect the safety switch 2, and the washing machine can operate normally; when the door cover is opened, the washing machine stops operating.

[0066] When the outer tub is overloaded, the input portion of the impact control rod 4 rotates outward, and the second output portion 43 rotates inward, pushing the second elastic sheet 22 downward away from the first elastic sheet 21, disconnecting the safety switch 2. During the overload process, since the control rod 4 rotates outward, the second output portion 43 pushes the second elastic sheet 22 away from the first elastic sheet 21. Even if the door cover is closed and the first elastic sheet 21 moves toward the second elastic sheet 22, it cannot contact and connect with the second elastic sheet 22, so the safety switch 2 is disconnected and the washing machine stops running.

[0067] Furthermore, the second elastic piece 22 includes a contact piece 221 and a pressing piece 222 .

[0068] The contact piece 221 is disposed opposite to the first elastic piece 21, and the first output portion 33 of the pressure rod 3 is disposed opposite to the contact piece 221, and is located on the opposite side of the contact piece 221 and the first elastic piece 21. The pressing piece 222 is extended outward from the contact piece 221, and the second output portion 43 of the control rod 4 is disposed opposite to the pressing piece 222, and is located on the opposite side of the second elastic piece 22 and the first elastic piece 21.

[0069] The contact piece 221 of the second spring piece 22 is arranged opposite to the first spring piece 21, and the pressing piece 222 of the second spring piece 22 deviates from the first spring piece 21. When the pressure rod 3 presses the first pressure piece, it can press the contact piece 221 of the second spring piece 22, and the control rod 4 can press the pressing piece 222, which will not affect each other when the pressure rod 3 is pressed and triggered. The structure is simple and the triggering effect is good.
