And, it may be effective that the corresponding action portion is a corresponding protrusion protruding toward the protrusion side on a predetermined opening angle position of the door.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

1 is an exploded perspective view of a washing machine according to the present invention, FIG. 2 is an enlarged view of the main part of FIG. 1, FIG. 3 is an enlarged view of the main part of FIG. 2, and FIG. 4 is a coupled state along the line IV-IV of FIG. 3. 5 is an enlarged cross-sectional view of a coupled state along the line VV of FIG. 3. As shown in these drawings, the washing machine according to the present invention, like the conventional washing machine, has a casing 1 having an upward opening and having a front opening 3 formed thereon, which is coupled to the upper end of the casing 1. A top cover 5 having a plate shape and a door 7 engaged to pivotally open and close the front opening 3 of the casing 1.

A detergent container 9 is coupled to an upper front region of the casing 1, and a front operation part 11 having a plurality of operation buttons 13 is provided at one side of the detergent container 9. The water supply pipe connection part 14 is provided in the back area | region of the casing 1, and the water supply pipe connection part 14 is provided with the water supply valve 16 so that the flow of wash water may be interrupted. In the casing 1, a tub 15 having a drum shape having one side open is supported by a plurality of suspension devices 17, and a shock absorber 18 is radially coupled to the lower side of the tub 15. .

In the tub 15, the spin basket 19 is rotatably provided along the front and rear directions of the casing 1. The spin basket 19 has a plurality of dewatering holes 21 formed therethrough along the circumferential surface thereof, and the rotating shaft 23 extends outwardly on the opening opposite side of the spin basket 19. A driven pulley 25 is coupled to an end of the rotary shaft 23, and a drive motor 27 is coupled to a lower region of the tub 15. The driving pulley 29 is coupled to the rotation shaft of the drive motor 27, and the driving pulley 29 and the driven pulley 25 are connected to each other by the belt 31 so as to be integrally rotatable.

A circular front opening 3 is formed in the front central region of the casing 1 for entering and exiting laundry, and a door gasket 8 having a circular ring is coupled to the front opening 3. A hinge bracket 46 for pivotally supporting the door 7 is coupled to the left edge of the front opening 3.

Hinge bracket 46 is a fixing portion 47 coupled to the edge of the front opening (3), and protruded inwardly from the fixing portion 47 and the upper and lower hinge pins 51 and the lower hinge pins 53, respectively. Has a hinge pin support 48 formed. The upper hinge pin accommodation portion 59 and the lower hinge pin accommodation portion in which a hinge pin accommodation hole 61 is formed on one side of the door 7 to support the upper hinge pin 51 and the lower hinge pin 53, respectively. 65 are formed, respectively.

On the other hand, at the lower end of the upper hinge pin accommodating portion 59, a projection 63 projecting downward corresponding to a predetermined rotational angle position of the door 7 is formed. The upper surface 55 of the hinge pin support portion 49, which is in contact with the lower surface of the upper hinge pin accommodation portion 59, has a projection 63 over a rotational section from the predetermined opening angle position of the projection 63 until it is fully opened. A guide inclined surface 57 is formed as a counteracting portion that applies resistance to rotation in the closing direction of the " The guide inclined surface 57 is gradually guided downwardly to the projection 63 during the open rotation of the projection 63, and is disposed to be inclined upwardly with the projection 63 during the rotation in the closing direction to apply resistance to the closed rotation.

By this configuration, the hinge bracket 46 is fastened and fixed to the edge of the front opening 3, and the upper hinge pin 51 and the lower hinge in the upper hinge pin accommodating part 59 and the lower hinge pin accommodating part 65 are fixed. The pins 53 are each received. Next, the upper hinge pin accommodating part 59 and the lower hinge pin accommodating part 65 are fixed to the door 7, respectively. When the door 7 is to be opened, the handle 7 provided on the hinge opposite side of the door 7 is grasped and pulled forward. Then, the door 7 rotates the upper and lower hinge pins (51, 53) to the axis. At this time, the protrusion 63 protruding at the lower end of the upper hinge pin receiving portion 59 is rotated while being in contact with the upper surface 55 of the hinge pin support 49 is guided downward along the guide inclined surface (57). When the door 7 is opened, the rotational inertia at the time of opening acts as a reaction force in a part of the closing direction. The door 7 is restrained from being closed because the downwardly projecting projection 63 comes into contact with the guide inclined surface 57 formed to be inclined upward with respect to the closing rotation direction.

In the above-described and illustrated embodiments, the protrusions are formed downward on the hinge pin receiving portion side of the door, and the guide inclined surface is formed in the hinge pin area as a corresponding action portion, but is described laterally in the axial direction of the hinge pin. An upwardly inclined camp profile may be formed to form a protruding protrusion and to resist the protrusion when the protrusion is rotated in a closed direction corresponding to the rotational position of the protrusion.

In addition, if a downwardly projecting protrusion is formed on the hinge pin receiving portion side and a corresponding protrusion protruding toward the protrusion is provided in the corresponding hinge pin area, the door is prevented from closing due to mutual contact when the door is rotated in the closing direction. can do.

As described above, according to the present invention, there is provided a washing machine capable of suppressing the door from being closed accidentally by applying a resistance to the closing rotation of the door within a predetermined angle range.
