Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a door closing structure for appliances and the like, and more particularly to a door closing structure using a magnet.

(Prior Art) Conventionally, as a structure for closing a door pivotally attached to a main body of an appliance or the like, a magnet is attached by adhering a magnet to each other on the back surface of the movable end of the door and the outer surface of the main body. , There is one in which the door is closed while the magnets are attracted to each other.

(Problems to be solved by the invention) However, in the above-described closing structure, the magnet on the main body side is exposed on the outer surface and can be seen when the door is opened, which is not preferable in appearance. In addition, since the magnets are directly attracted to each other every time they are closed, a considerably strong impact is applied, so that there is a problem that the magnet is dismounted or chipped.

The object of the present invention is to attach one magnetic attraction member to the inner surface of the main body so that it cannot be seen from the outside, and the magnetic attraction member in the direction of attachment to the back surface of the door does not come into contact with the main body. An object of the present invention is to provide a door closing structure that is closed by mutual attraction.

(Means for Solving the Problem) In order to solve the above problems, the present invention provides a door closing structure in which one end is pivotally attached to a main body and covers the outer surface side of the main body so that the door can be opened and closed. On the back side at the end of the
Of the first magnetic attraction body is attached to the inner surface of the main body so as to face the mounting position of the first magnetic attraction body, and the second magnetic attraction body which mutually attracts the first magnetic attraction body is attached, and the door is closed. The closing structure has a gap between the first magnetic attraction body and the outer surface of the main body when the door is in contact with the outer surface of the main body.

(Operation) According to the present invention, in the closed state of the door, the door contacts the outer surface of the main body, and at this time, there is a gap between the first magnetic attraction body and the outer surface of the main body. Through the distance between the inner surface and the outer surface and the gap, an attractive force acts between the first magnetic attraction body and the second magnetic attraction body to lock the door to the outer surface of the main body.

(Embodiment) FIG. 1 is a sectional view of a door closing structure showing an embodiment of the present invention,
FIG. 2 is a rear perspective view of the door.

In FIG. 1, reference numeral 1 denotes a synthetic resin main body of a deodorizing device equipped with a blowing means, in which various parts (not shown) of the device are housed. The back plate 2 is attached by screwing to the back side thereof. The front side of the main body 1 has an opening 3 for attaching components and ventilation, and the back plate 2 has a plurality of ventilation holes 4.

5 is a synthetic resin door, one end of which is hinged to the main body 1 by a hinge 6 and covers the outer surface side of the opening 3 of the main body 1,
It can be opened and closed by rotating around its pivot point. As shown in FIG. 2, the door 5 has a plurality of ventilation holes 7 to allow ventilation between the main body 1 and the outside with the door 5 closed. The door 5 has a box-like shape with its peripheral edge 8 projecting toward the back side, and has a protrusion 9 having a height of about 0.5 mm at one or a plurality of ends of the peripheral edge 8. The main body 1 has a recess 10 for receiving the peripheral edge 8 and contacting the projection 9.

Reference numeral 11 denotes a disk-shaped first magnet as a first magnetic attraction body, which is attached to the back surface of the end of the door 5 on the open / close movable side by being adhered. As shown in FIG. 1, the first magnet 11 has the protrusion 9 in contact with the recess 10,
A gap t _{1 of} about 0.5 mm between the top and the outer surface of the main body 11.
The height and the related dimensions of the protrusion 9 and the like are set so as to have

Reference numeral 12 is a disk-shaped second magnet as a second magnetic attraction body, which is the first magnet 11 when the door 5 is closed.
And is attached to the inner surface of the main body 1 so as to face it. Therefore, the magnets 11 and 12 are separated from each other by a distance composed of the gap t ₁ and the thickness t _{2 of the} main body 1, and have magnetizing directions and magnetic forces that attract each other at this distance. There is.

In the above configuration, when the door 5 is closed, the protrusion 9 of the door 5 abuts the recess 10 of the main body 1, and in this state, a gap t ₁ is formed between the first magnet 11 and the outer surface of the main body 1. The door 5 is attracted to the main body 1 side by the attraction force acting between the first magnet 11 and the second magnet 12 without contacting each other, and the projection 9 is locked in the recess 10. To be done.

In this embodiment, each magnetic attraction body is the magnet 11 or 12, but either one may be a magnetic body attracted to the other magnet. Further, the protrusion 9 is provided on the peripheral edge 8 of the door 5, and the protrusion 9 is brought into contact with the outer surface of the main body ₁ to secure the gap t ₁ .
The protrusion may be provided on the main body 1 side or both the main body 1 side and the door 5 side.

(Effect of the Invention) As described above, according to the present invention, the magnetic attraction body on the main body side is attached to the inner surface of the main body and cannot be seen from the outside even when the door is open, so that the appearance is not spoiled. Then, when the door is closed, the magnetic attracting bodies are brought into contact with each other without being brought into contact with each other, and the magnetic attracting bodies on the door side are brought into contact with the main body to be closed. Since the magnetic attraction body on the door side does not damage the main body and the magnetic attraction bodies are not impacted, the magnetic attraction bodies are not detached or damaged.
