DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a locking device for a lid of a household appliance, such as a clothes dryer.

Configuration of a conventional example and its problems A lid locking device for opening and closing a main body opening of a clothes dryer will be described as an example of a conventional device lid locking device. Figure 1 is a front view of the clothes dryer, where 1 is the main body, 2 is a lid that opens and closes the opening of the main body 1, and 3 is the lid 2.
It is a window fixed to the Reference numeral 4 denotes an operating body for opening and closing the lid 2. 2 and 3 are cross-sectional views of the locking device section. The operating body 4 has a pivot support 5, which pivotally supports a shaft portion 7 of a locking element 6, thereby making the locking element 6 rotatable. The locking element 6 has a hook portion 8 fixed to the main body 1.
engage with. Further, the locking element 6 is provided with a rib 9 and is brought into contact with the operating body 4 so that the locking element 6 engages with the hook part 8 and stops at an appropriate position. The lid 2 and the locking element 6 are provided with end portions 10 and 11, respectively, and a substantially U-shaped spring plate 1 is provided between the lid 2 and the locking element 6.
2, and attach one end of the spring plate 12 to the end 10 of the lid 2.
Then, insert the other end into the end portion 11 of the locking element 6, and fit the spring plate 12 therein. This spring plate 12 always urges the locking element 6 in the direction of engagement with the hook portion 8, and
The operating body 4 is urged in the engagement direction via the rib 9.
Further, to release the lock, if the operating body 4 is lifted in the A direction, the operating body 4 rotates around the shaft portion 13, and the locking element 6 is pushed in the B direction via the rib 9. Therefore, the locking element 6 moves in the direction of disengaging from the hook portion 8, and the locking is released. FIG. 3 is a cross-sectional view of the lock in the unlocked state. When assembling this locking device, as shown in FIG.
The shaft part 13 provided on the upper part of the operating body 4 is inserted into the hole 14 provided in the lid 2, and one end of the spring plate 12 is attached to the end 10 of the lid 2, and the other end is locked. Child 6
Finally, a pin 17 is inserted into a hole 12 provided in the lid 2 and a hole 16 provided in the operating body 4 to be pivotally supported, thereby making the operating body 4 rotatable. However, this configuration has a problem in that each component is likely to come off until the pin 17 is inserted, making it difficult to assemble and replace.

Purpose of the Invention The present invention provides a lid locking device for equipment which solves these conventional problems, has a simple structure, and improves serviceability such as assembly and parts replacement.

Structure of the invention The lid locking device for the device of the present invention has a locking element integrally formed with an elastic biasing member, and an operating body rotatably provided on the lid has a shaft portion of the locking element in a predetermined direction. It has a partially open hole for accepting the lock at the center and preventing it from coming off in other directions. The configuration is such that this is carried out by

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 5 and 6 are cross-sectional views of the locking device section. The operating body 18 has a pivot support 19,
The shaft portion 21 of the locking element 20 is pivotally supported, and the locking element 20 is rotatable. The locking element 20 engages with a hook portion 23 fixed to the main body 22. Further, the locking element 20 is provided with a rib 24, so that the locking element 20 can be attached to the hook part 23.
The operating body 18 is brought into contact with the operating body 18 so as to engage with the operating body 18 and stop at an appropriate position. Furthermore, a biasing member 25 is integrally formed on the locking element 20, and this biasing member 25 biases the lid 26 to constantly keep the locking element 20 in the hook portion 23.
The operating body 18 is urged in the engaging direction via the rib 24. Further, to release the lock, if the operating body 18 is lifted in the C direction, the operating body 18 rotates around the shaft portion 27, and the locking element 20 is pushed in the D direction via the rib 24. Therefore, the locking element 20 moves in the direction of disengaging from the hook portion 23, and the locking is released. FIG. 6 is a cross-sectional view of the lock in the unlocked state. When assembling this locking device, as shown in FIG.
The shaft support 1 of the operating body 18 is
9, and insert the shaft portion 27 provided at the top of the operating body 18 into the hole 28 provided in the lid 26,
Finally, a pin 31 is inserted into a hole 29 provided in the lid 2 and a hole 30 provided in the operating body 18 to provide pivotal support, thereby making the operating body 18 rotatable. In this configuration, as shown in FIG. 8, when the locking element 20 is rotatably fitted to the operating body 18, the urging member 25 of the rotating locking element 20 and the operating body 18 come into contact with each other. Thus, the position of the locking element 20 is regulated in the rotation direction. Therefore,
Unless a force is applied that resists the biasing force of the biasing member 25, the locking element 20 will not come off the operating body 18. When disassembling, as shown in FIG. 9, the locking element 20 may be rotated against the biasing force of the biasing member 25 and pulled in the E direction.

Effects of the Invention As is clear from the above embodiments, the device lid locking device of the present invention has an elastic biasing member integrally formed with the locking element to restrict the position of the locking element in the rotating direction. The structure is simplified by the structure in which the biasing member and the operating body come into contact with each other, and
This makes it possible to improve serviceability such as assembly and replacement.
