Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a washing machine having a lid that covers an input port.

[0002]

[Prior art]

 Generally, the lid of a fully automatic washing machine is composed of a front lid 1 and a rear lid 2 as shown in the figure, and the front lid 1 covers the operating portion 3 when the lid is closed. Further, the detection when the lid is opened is detected by lowering the lever 6 of the safety switch 5 provided in the rear electrical component storage section 4 downward. Therefore, as shown in FIG. 5A, the safety switch 5 is turned off to detect the opening of the lid, so that the front lid 1 is opened by the height H and the lever receiving portion 2a of the rear lid 2 is centered on the axis O. Then, the contact is turned off by turning it down by the stroke h. Further, during operation, the contact point of the safety switch 5 is as shown in FIG. 5 (b), the lever receiving portion 2a of the rear lid 2 pivots and moves upward by the stalking h, pushing the lever 6 upward, and the contact point. It is turned on. Therefore, the height H is larger than the straw h by the ratio of the distance L between the fulcrum of rotation O and the tip of the front lid 1 and the distance l between the fulcrum of rotation O and the contact surface of the lever 6, As shown in, the height H is an opening size into which the hand can be inserted when the total length L of the lid is large, and the hand can be operated while the washing and draining tank 7 is rotating (the safety switch 5 remains ON). It came in and was very dangerous. Also, due to the recent increase in the size of washing machines, the lid itself is becoming larger, and the danger is increasing.

[0003]

[Problems to be solved by the device]

 As described above, in the conventional configuration, the hand may come in through the gap on the front surface of the lid during operation, and the dehydrating and washing tub 7 rotating at high speed may come into contact with the hand, thus improving the safety of the lid. There was a need.

The present invention is intended to improve safety by paying attention to the above conventional problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention intends to improve safety and design by providing an opening / closing lid on a handle portion of the lid and providing a locking mechanism interlocking with the opening / closing lid. It is a thing.

[0006]

[Action]

 As described above, according to the present invention, by opening and closing the opening / closing lid provided on the handle portion of the lid, when the lid is closed, the lock bar interlocking with the opening / closing lid is engaged with the through hole of the upper panel to lock the lid. When opening the lid, lower the open / close lid so that the lock rod will be disengaged from the through hole of the upper panel, the lock will be released, and the lid can be opened.

Further, the opening / closing lid can cover the concave portion which is conventionally required for putting a hand, and prevents detergent, dust, and dust from entering the concave portion, and has a flat upper surface to improve the design. Can be improved.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

In the drawing, reference numeral 11 denotes a front lid, which has a concave grip portion 12 in a central portion, a through hole 13 in a rear side wall, a through hole 14 in a flat surface portion, a shaft holding portion 15, and both side walls of the grip portion 12. Has a holding hole 16.

A handle having an opening / closing lid 18 having a shaft portion 17 that engages with the shaft holding portion 15 and claw portions 19 and 20 that engage with the through hole 13 and the through hole 14 so as to cover the upper portion of the handle portion 12. It is pressed and held by the cover 21. On both sides of the opening / closing lid 18, there are provided projections 22 that are gently inclined in a circumferential shape around the shaft 17 and a tongue piece 23 is provided at the lower end. The tongue piece 23 is made of resin. The opening / closing lid 18 is provided so as to be biased upward by utilizing elasticity. The protrusions 22 on both sides of the opening / closing lid 18 push the actuating rod 24 outward and the lock rod 25 connected to the operating rod 24 outward when the opening / closing lid 18 is closed (normal state). The front end of the lock rod 25 is inserted into the through hole 27 and the front lid 11 is locked. When the opening / closing lid 18 is pushed down (when the front lid 11 is opened), the protrusion 22 rotates around the shaft 17, and the actuating rod 24 moves inward along the gentle inclination of the protrusion 22, As a result, the lock rod 25 also moves inward, the lock rod 25 is disengaged from the through hole 27 of the upper panel 26, and the lock is released.

Further, the structure of the operating rod 24 and the lock rod 25 will be described in detail. The lock rod 25 is housed inside the operating rod 24 on one side so as to be biased outward by the spring 28. Has an inclined portion 30 which is inclined downward. The actuating rod 24 has a lock rod 25 therein, one side of which is in contact with the protruding portion 22 of the opening / closing lid 18, and the other is a contact portion 31 of the spring 29, which is provided on both sides of the front lid 11. The actuating rod 24 is biased inward between the holding rib 32 and the holding rib 32 and is pressed against the protrusion 22. Therefore, as described above, when the opening / closing lid 18 is closed, the operating rod 24 and the lock rod 25 are moved outward by the protrusions 22 and the tip of the lock rod 25 is engaged with the through hole 27 of the upper panel 26. Then, the front lid 11 is locked. In addition, when the open / close lid 18 is pushed down and pushed down, the operating rod 24 moves inward along with the inclination of the protruding portion 22 by the biasing force of the spring 29 in conjunction with the rotation of the protruding portion 22. The tip of the lock rod 25 is pulled through the through hole 27 of the upper panel 26, and the lock is released. When the front lid 11 is closed from the open state, the inclined portion 30 at the tip of the lock rod 25 hits the corner portion 33 of the upper panel 26, the lock rod 25 moves inward, and the operating rod 24 When the spring 28 installed inside is pushed, the front lid 11 is housed in the upper panel 26, and at the same time, the lock rod 25 moves outward due to the urging force of the spring 28, and the tip of the lock rod 25 passes through the through hole 27. Is engaged and locked.

[Effect of device]

 As will be apparent from the above description of the embodiments, the present invention provides the lid with the opening / closing lid and the locking mechanism interlocked with the opening / closing lid, so that the lid is locked when the lid is closed. Therefore, the lid cannot be opened by holding the tip of the lid, and the hand cannot be mistakenly inserted through the gap of the lid as shown in FIG. In addition, since the opening / closing lid covers the concave part of the handle, detergent, dust, dust, etc. do not enter the concave part and the lid is flat overall, which is excellent in design. It becomes a thing.
