Description

[Detailed Description of the Invention] The present invention relates to the structure of a washing machine, and relates to a structure for attaching a lid to a washing machine to close an inspection port opened at the back surface of the outer body of the washing machine.

The conventional lid mounting structure is such that the lid is attached with screws to the periphery of the inspection port opened on the back of the outer body of the main body, but both the outer body and the lid are made of thin copper plates. Because of this, the peripheral edge of the inspection port and the peripheral edge of the lid are often formed with unevenness, making it difficult to form them flush.

Therefore, when these two parts are fixed with screws, a small gap is created between the screwed part and the part where the tightening pressure is weak, that is, between the lid body and the periphery of the inspection port, and the reverse rotation occurs. When the main body vibrates, the vibration sound is amplified by this gap i,
It has the disadvantage of generating a so-called chattering sound.

The present invention is constructed to solve the above-mentioned drawbacks. An embodiment of the present invention will be described below with reference to the drawings. 1 is an outer shell that constitutes the main body of the washing machine, and 2 is an opening on the back side of the outer shell 1. A plurality of screw holes 3 are formed in the peripheral edge of the inspection port.

Reference numeral 4 denotes a lid that is attached to the peripheral edge of the inspection port 2 to close the inspection port 2. A screw hole 5 is formed in the peripheral edge of the lid in correspondence with the screw hole 3, and screw holes 5 are formed on both sides of the screw hole 5. A bulge 6 that projects inward is formed, and a bulge 7 that projects outward is further formed between one screw hole 5 and the next screw hole 5.

Reference numeral 8 denotes a tapping screw that is screwed into the screw hole 3 through the screw hole 5 of the lid 4 in order to fix the lid 4 to the peripheral edge of the inspection port 2, that is, the outer body 1. When the cover body 4 is inserted, only its bulge 6 is brought into pressure contact with the periphery of the inspection port 2, and the other parts are formed flush with the bulge 7, so that there is no space between the bulge 6 and the periphery of the inspection port 2. Spaced at regular intervals.

As described above, in the present invention, a screw hole is formed at the periphery of the inspection port that opens on the back surface of the outer body of the main body, and a screw hole is formed in the periphery of the lid body that closes the inspection port in correspondence with the screw hole. forming a hole, and forming a bulge protruding inward around the same screw hole and a bulge protruding outward between the same screw hole and the next screw hole, respectively; The lid is fixed to the periphery of the inspection port by inserting a tapping screw through the screw hole of the lid into the screw hole on the periphery of the inspection port. Only the bulge formed around the periphery is pressed against the periphery of the inspection port, and the other parts are reinforced by the bulge projecting outward and are formed flush with each other. are placed at regular intervals.

Therefore, even if the operating body vibrates, there is no minute gap between the lid body and the periphery of the inspection port, so there is no chattering sound like in the past. This can be effectively suppressed by a suitable configuration.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; FIG. 1 is a perspective view of a washing machine, FIG. 2 is a perspective view of the main parts thereof, and FIG. 3 is a sectional view taken along line AA in FIG. 2. In the figure, 1 is the outer shell of the main body, 2 is the inspection port, 3 is the screw hole, 4 is the lid, 5 is the screw hole, 6 and 7 are the bulges, and 8 is the screw.

Claims (1)

[Scope of utility model registration request] In a washing machine in which the periphery of a lid that closes the inspection port is attached to the periphery of the inspection port opening on the back side of the outer body of the main body with screws, the periphery of the inspection port has a plurality of screw holes. On the other hand, a screw hole corresponding to the screw hole is formed in the peripheral edge of the lid body, and a bulge that protrudes inward around the screw hole is formed between the same screw hole and the next screw hole. When the peripheral edge of the lid body is attached to the peripheral edge of the inspection port with a screw, only the bulge formed around the screw is formed. A washing machine characterized by being pressed against the periphery of an inspection port.
