Description

Technical Field

[0001] This utility model relates to a washing machine door switch device and a washing machine using the switch device. Background Technology

[0002] In daily life, the door of a front-loading washing machine typically only serves to open and close the washing drum, resulting in low utilization of its internal space. Furthermore, front-loading washing machines usually mount electrical components on the front panel or control panel. These components require wiring to connect to the internal circuitry of the washing machine to function properly. If these components were installed inside the glass bowl of the door, the gap between the glass bowl and the washing machine body would make wiring and connections extremely difficult, affecting the compactness and aesthetics of the structure.

[0003] To address the challenge of supplying power to electrical components installed inside a glass bowl, several patents have been published, such as Chinese Patent CN109487510A, "A Drum Washing Machine." This patent allows for locking and opening the washing machine door via a push-push or push-pull mechanism, improving user convenience. However, this patent still requires further simplification of the door unlocking and opening process for greater ease and speed. Another example is Chinese Patent CN108004729A, "A Washing Machine Door Lock Structure and Drum Washing Machine." This patent allows users to lock or open the washing machine door even in the event of a complete power outage, while maintaining the washing machine's aesthetic consistency. However, this patent still requires further optimization of the lock block and door lock switch structure to improve the convenience and reliability of closing the door.

[0004] In summary, the existing technology still has the above-mentioned problems. How to improve the utilization rate of the door structure without changing the shape of the door, facilitate the power supply to the electrical components inside the glass bowl, and improve the convenience of opening and closing the door, still needs to be further improved and perfected by those skilled in the art. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a washing machine door switch device that can both supply power to electrical components installed in the glass bowl and facilitate user operation, in light of the above-mentioned existing technology.

[0006] The second technical problem to be solved by this utility model is to provide a washing machine device equipped with the aforementioned washing machine door switch device, in view of the current state of the prior art.

[0007] The technical solution adopted by the present utility model to solve the above first technical problem is as follows: A washing machine door switch device, the washing machine door of which includes a fixedly arranged panel bracket, glass bowls installed on both sides of the panel bracket, and an openable and closable door body. It is characterized in that: The switch device includes

[0008] a plug connector for external power supply, which is installed on the panel bracket;

[0009] a wiring terminal, which is pluggable and mating with the plug connector, and is electrically connected to an electrical component arranged in the glass bowl;

[0010] When the plug connector and the wiring terminal are in a closed state, the switch device is electrically conductive, and the electrical component in the glass bowl is powered on; when the plug connector and the wiring terminal are in an open state, the switch device is closed, and the electrical component in the glass bowl is powered off.

[0011] For the convenience of processing and assembly, preferably, the plug connector includes a base and a locking tongue vertically extending outward from the base. The front end of the locking tongue is provided with a protruding male terminal, and a locking hole is also formed on the locking tongue.

The locking buckle cooperates with the locking hole to achieve the closing and opening of the plug connector and the wiring terminal; a concave female terminal that can be inserted and electrically conductive with the male terminal of the locking tongue is also arranged in the wiring terminal.

[0013] For making the pluggable and mating more reliable and preventing slippage, as a further preference, the locking buckle of the wiring terminal includes a rotating shaft pivotally connected in the end shell. The wiring terminal also includes a locking hook that can be snapped onto the locking hole. The locking hook is fixed on the rotating shaft and is linked with the rotating shaft. Thus, the locking hook can be buckled on the locking hole to achieve a tight connection between the plug connector and the wiring terminal.

[0014] For the convenience of the locking hook to be inserted into and slid out of the locking hole, preferably, the locking hole is square, and an inclined surface for facilitating the insertion and sliding out of the locking hook is arranged on one side edge of the locking hole that is engaged with the locking hook.

[0015] For ensuring the reliability of electrical connection, preferably, a concave hole is formed on the front end face of the locking tongue, the male terminal is formed in the concave hole, the end of the male terminal is flush with the end face of the concave hole, and a first hole in the shape of a "return" character is formed between the male terminal and the concave hole.

[0016] To facilitate insertion and mating, preferably, the terminal block has a protrusion inside its end housing. The protrusion has a second hole along its axial direction, which serves as the female terminal. Furthermore, the cross-sectional size of the protrusion is adapted to the cross-sectional size of the first hole.

[0017] To facilitate the assembly and fixation of the connector, preferably, the base of the connector is provided with mounting holes that can be connected to the panel bracket, and the two sides of the base are also provided with first connectors that can be electrically connected to an external power supply.

[0018] To facilitate electrical connection between the terminal block and electrical components, preferably, the terminal block is provided with a second connector at the other end of the end housing, which can be electrically connected to the electrical components inside the glass bowl.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 7 As shown in the figure, this embodiment discloses a washing device, which includes a washing tub assembly and a washing machine door installed at the front of the washing tub assembly, and the washing machine door is provided with a switch device.

[0034] The washing machine door includes a door frame 1, a hollow panel bracket 2 fixedly installed on the door frame 1, a glass bowl 3 protruding into the washing tub assembly installed on the inner side of the panel bracket 2, a hollow glass panel 4 installed on the outer side of the panel bracket 2, and an openable door 5 installed on the outer side of the glass panel 4.

[0035] The switching device in this embodiment includes a connector 6 and a terminal block 7. A recess 21 is provided on the panel bracket 2, and the connector 6 is installed in the recess 21 of the panel bracket 2. The connector 6 can be connected to an external power supply, and the power cords 8 at both ends of the connector 6 can also be fixed to the panel bracket 2. (See also...) Figure 7 Terminal 7 and connector 6 can be plugged into each other. Terminal 7 is electrically connected to electrical components located inside the glass bowl 3. See [link / reference]. Figure 1 , Figure 4 ;

[0036] With the connector 6 and terminal 7 closed, the switch is electrically connected, and the electrical components inside the glass bowl 3 are energized.

[0037] With the connector 6 and terminal 7 open, the switch is electrically closed, and the electrical components inside the glass bowl 3 are de-energized.

[0038] For ease of processing and assembly, such as Figure 5As shown in the figure, the plug connector 6 of this embodiment includes a base 61 and a locking tongue 62 extending vertically outward from the base 61. The front end of the locking tongue 62 is provided with a male terminal protruding outward. The locking tongue 62 is also provided with a locking hole 621, and the locking hole 621 is square.

[0039] To ensure the reliability of electrical connection, two concave holes are provided on the front end face of the locking tongue 62, and a convex joint 63 serving as a male terminal is formed in each concave hole. The end of the convex joint 63 (male terminal) is flush with the end face of the concave hole, and a first hole 622 in the shape of a "return" character is formed between the convex joint 63 (male terminal) and the concave hole.

[0040] To achieve the assembly and fixation of the plug connector 6, two mounting holes 64 that can be connected to the panel bracket 2 are also provided on the base 61 of the plug connector 6. In addition, a first joint 611 that can be electrically connected to an external power supply is provided on each side of the base 61.

[0041] Correspondingly, as Figure 6 shown in the figure, the wiring terminal 7 includes an end shell 71 with an open end 712 and a movable locking buckle disposed in the inner cavity of the end shell 71. The wiring terminal 7 is provided with a second joint 711 at the other end of the end shell 71 that can be electrically connected to the electrical components in the glass bowl 3.

[0042] The locking buckle of the wiring terminal 7 includes a rotating shaft 72 pivotally connected to the inside of the end shell 71. The wiring terminal 7 also includes a locking hook 73 that can be snapped onto the locking hole 621. The locking hook 73 is integrally formed with the rotating shaft 72 and is linked to the rotating shaft 72. The rotating shaft 72 is controlled by a motor 74 to rotate according to the working state of the washing machine.

[0043] To facilitate the insertion and removal of the locking hook 73 into and out of the locking hole 621, an inclined surface 623 that facilitates the insertion and removal of the locking hook 73 is provided on one side edge of the locking hole 621 of the plug connector 6 where it is engaged with the locking hook 73.

[0044] An inner concave female terminal that can be inserted and electrically connected to the male terminal of the locking tongue 62 is also provided inside the wiring terminal 7. Specifically, two convex columns 75 are provided inside the end shell 71 of the wiring terminal 7. A second hole 751 serving as a female terminal is axially provided in each convex column 75, and the cross-sectional size of each convex column 75 is adapted to the cross-sectional size of the first hole 622 on the corresponding plug connector 6.

[0045] Thus, the locking hook 73 can be buckled onto the locking hole 621, and the cooperation between the locking buckle and the locking hole 621 realizes the closing and opening of the plug connector 6 and the wiring terminal 7; the female terminal is inserted into the male terminal to achieve the electrical conduction between the plug connector 6 and the wiring terminal 7.

[0046] The working process of the switch device of this embodiment is as follows:

[0047] When the washing machine is not in operation (i.e., the "Start" button is off or paused), the rotating shaft 72 and the locking hook 73 are in the reset state, such as... Figure 2 As shown, at this time, the connector 6 and the terminal 7 are in an unlocked state, the washing machine door can be opened, the lock hole 621 of the connector 6 and the lock hook 73 of the terminal 7 are separated from each other, the circuit between the connector 6 and the terminal 7 is not connected, and the electrical components inside the glass bowl 3 are de-energized.

[0048] When the washing machine is working normally (i.e., after the "Start" button is pressed), the motor 74 starts working, and the rotating shaft 72 drives the locking hook 73 to rotate and engage with the locking hole 621, as shown. Figure 3 As shown, at this time, the connector 6 and the terminal 7 are in the locked state, and the washing machine door cannot be opened. The lock hole 621 of the connector 6 and the lock hook 73 of the terminal 7 are engaged with each other, and the circuit between the connector 6 and the terminal 7 is connected, so the electrical components inside the glass bowl 3 are powered on and work. Until the washing or drying cycle is completed, that is, the "start" button changes to off or pause again. At this time, the motor 74 drives the rotating shaft 72 to rotate to the reset state, the connector 6 and the terminal 7 return to the unlocked state, and the washing machine door can be opened again.

[0049] This embodiment employs a user-friendly washing machine door switch device. Through the interlocking design of the connector and terminal 7, the washing machine door is energized after closing, allowing control of the electrical components inside the glass bowl 3. This switch device not only solves the problem of powering electrical components installed inside the glass bowl 3, but also enhances the utilization of structure and space, achieving multiple uses without altering the original structural shape.
