The present invention relates to a door and a washing machine having the same, and more particularly, when a user closes a door of a home appliance including a washing machine, the door can close or prevent noise or vibration from occurring while the door is closed. It relates to a washing machine having this.

In general, a washing machine, which is a household appliance that processes clothes such as washing or drying, is classified into two types. The rotating shaft of the spin basket or drum that handles laundry such as clothes is divided into vertical or horizontal. The washing machine in the vertical rotation axis is called the top loading washing machine, and the washing machine in the horizontal direction is the front load. Or a front washing washing machine or drum washer.

In these washing machines, doors are formed to accommodate laundry, and a crash noise / vibration of the door occurs in the process of closing the door after the laundry is put in or taken out of the laundry space, which causes the washing machine to be broken.

In particular, since the door of the top load washing machine is affected by gravity in the closing process, the door closes relatively quickly when the door is closed, and there is a problem such that the user is injured by the fast closing door.

The present invention has been made to solve the problems of the prior art as described above, the first object of the present invention is to provide a door having a mitigation means or closing delay means to allow the door to close slowly and a washing machine having such a door will be.

It is a second object of the present invention to provide a door having a mitigating means or a closing delay means for reducing a collision noise of a door when the door is closed, and a washing machine having such a door.

A third object of the present invention is to provide a door having a built-in door opening and closing device including a mitigation means and a washing machine having the same, which can easily replace the opening and closing device and the door in which the opening and closing device is broken.

The present invention, in order to achieve the object as described above, the door body; A first slot formed in the door body; A second slot formed at one side of the first slot; A connecting rod having one end located in the first slot and the other end located in the second slot; And a relaxation means installed in the second slot and connected to one end of the connecting rod to slowly close the door body.

As described above, the door body is gradually closed by the expansion or contraction of the alleviating means connected to the connecting rod moving along the first slot and the second slot. This can be prevented.

Here, the first slot is inclined with respect to the upper and lower surfaces of the door body, the second slot is preferably formed to be parallel to the upper and lower surfaces of the door body. This is because, if the first slot is parallel to the upper and lower surfaces of the door body without inclination, the rear part of the door may collide with the main body of a home appliance such as a washing machine when the door is opened and closed.

In addition, the relief means is effectively a spring that is compressed as the door is closed. That is, the length of the door decreases as the door is closed than when the door is opened, and by adopting a spring that is compressed as the mitigating means, the elastic restoring force of the spring to be compressed acts in a direction opposite to the closing direction of the door. Will slowly close.

On the other hand, one end of the connecting rod installed in the first slot is characterized in that the diameter is the same as the width of the first slot. In this way, by forming one end of the connecting rod installed in the first slot in a cylindrical shape and making the diameter of the cylindrical portion the same as the width of the first slot, one end of the connecting rod can slide along the first slot. And the sliding movement can be made smoothly opening and closing the door.

In addition, one end of the connecting rod positioned in the second slot is mounted with a support for supporting the relief means, and one end of the connecting rod with the support mounted to allow the support to slide along the second slot. And rotatably connected with respect to the support. By further forming a separate support between the one end of the connecting rod located in the second slot and the relief means, one end of the connecting rod located in the second slot is straight along the second slot by the support. You can rotate while exercising.

Here, the width of the connecting rod is characterized in that the taper toward one end installed in the first slot from the end installed in the second slot. This is to prevent the second slot and the connecting rod from interfering with each other during the movement of the connecting rod along the second slot.

On the other hand, the roller may be further formed on the outer surface of the door body facing the second slot with respect to the first slot. By further forming the roller as described above, it is possible to prevent one side of the door main body from colliding with the main body of the home appliance such as a washing machine during the opening and closing process of the door main body, and smooth the opening and closing operation of the door.

The door body may be made of tempered glass and a mold, and the first slot and the second slot may be formed in the mold. By making the door body made of tempered glass, the inside of home appliances such as a washing machine can be easily seen, and by forming a mold together therewith, the first slot and the second slot can be easily manufactured.

Here, a fluid cylinder that is compressed as the door is closed may be employed as the mitigating means. In other words, if the spring is used as a relieving means, the elastic force of the spring may be weakened as the spring is used for a long time. On the other hand, if the fluid cylinder is employed as the relieving means, the spring can be used more stably.

On the other hand, the present invention to achieve the above object, the casing; A door installed on one surface of the casing to accommodate laundry; And a closing delay means installed on the door to reduce the collision noise when the door is closed and to gradually close the door.

In particular, household appliances such as washing machines are frequently caused by collision noise of the door because the user frequently opens and closes the door in the process of washing the laundry, and in order to reduce the problem, the door is formed by forming the closing delay means in the door. Can be closed slowly.

Here, the closing delay means, the first slot formed in the door; A second slot formed at one side of the first slot; A connecting rod having one end located in the first slot and the other end located in the second slot; And an elastic member installed at the second slot and connected to one end of the connecting rod to slowly close the door body.

In addition, the present invention, the casing; A door installed on one surface of the casing to accommodate laundry; A tub installed inside the casing; And a spin basket rotatably installed inside the tub, wherein the door comprises: a door body; First and second slots formed in the door body; A connecting rod having one end located in the first slot and the other end located in the second slot; And a relaxation means installed in the second slot and connected to one end of the connecting rod.

Here, one end of the connecting rod installed in the first slot is formed with both sides of the pin, one of the pin is characterized in that it moves inside the first slot and the other is rotatably fixed to the casing. Thus, by forming a pin protruding to both sides at one end of the connecting rod moving in the first slot, one side of the pin is fixed to the casing and the other side to slide along the first slot, the door is the casing It can be opened and closed while maintaining the same position relative to.

The door may further include a roller moving along one surface of the casing as the door is opened and closed, and one surface of the casing contacting the roller may form a curved portion.

In addition, one surface of the casing in contact with the roller is characterized in that the stopper is formed to prevent the roller from excessively advancing as the door is opened. As such, by preventing the roller from further moving forward by the stopper, it is possible to prevent the door from being excessively opened and colliding with the control panel formed at the rear of the door.

Meanwhile, one end of the connecting rod installed in the first slot may move in the first slot as the roller moves along one surface of the casing. That is, since the roller moves along one surface of the casing to maintain a constant distance between the door and the casing, the connecting rod can slide along the first slot.

Here, the casing may be further provided with a buffer means for mitigating the collision between the door and the casing. In this way, by further providing a cushioning means in the casing, it is possible to prevent a collision noise between the door and the casing to some extent even if the means for gradually closing the door fails.

The objects and features of this invention will become more apparent from the following detailed description.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the configuration and operation according to an embodiment of the present invention.

However, in describing the present invention, a detailed description of known functions or configurations will be omitted for clarity of the gist of the present invention.

1 is a perspective view schematically showing a washing machine having a door according to the present invention. As shown in FIG. 1, the washing machine 1 according to the present invention includes a casing 10, a door 20 installed on one surface of the casing 10 to accommodate laundry, and an interior of the casing 10. It is configured to include a tub (not shown) installed in and a spin basket (not shown) rotatably installed in the tub.

Although not shown in Figure 1 tub and spin basket, it is clear that the tub and spin basket applied to the washing machine according to the present invention is not specifically shown because they are the same as those of a general washing machine.

The top cover 40 having a detergent inlet is formed on the upper side of the casing 10 in which the door 20 is installed, and a portion of the door 20 comes into contact with the top cover 40. On the other hand, the control panel 30 for selecting the driving course of the washing machine, etc. protruding from the upper back of the casing 10, the control panel 30 may be formed on the front portion of the casing (10).

In addition, the door 20 has a handle 50 is formed so that the user can easily open and close the door.

FIG. 2 is a cross-sectional view taken along cut line II-II of FIG. 1, illustrating a mechanism for opening and closing the door 20 and slowly closing the door 20 in this process.

First, the door includes a door main body 20, a first slot 23 formed on the door main body 20, a second slot 24 formed on one side of the first slot 23, and one end 25a. The other end 25b, which is located in the first slot 23 and the other end 25b, is installed in the connecting rod 25 and the second slot 24 located in the second slot 24, and is connected to one end 25b of the connecting rod 25. And a relieving means 26 for slowly closing the door body 20.

The door body 20 includes a mold 12 and a tempered glass 22 engaged with the mold 21. At this time, most of the door body 20 is preferably tempered glass (22). This is because, by forming most of the door body 20 with the transparent tempered glass 22, the washing state of the laundry and the like can be observed by the user's naked eye.

In addition, it is preferable to make the thickness of the mold 21 larger than the thickness of the tempered glass 22. Since the mold 21 is formed with the first slot 23 and the second slot 24 and the connecting rod 25, etc., the mold 21 must have a sufficient thickness to mount these parts. do.

The first slot 23 and the second slot 24 are formed in the mold 21 of the door body 20, and the first slot 23 is based on the front part of the washing machine 1. It is formed at the rear of the (20), the second slot 24 is formed in front of the first slot (23). In addition, the first slot 23 and the second slot 24 is preferably formed spaced apart from each other at regular intervals. However, the slots 23 and 24 are not necessarily formed to be spaced apart from each other, and both slots 23 and 24 are different if the diameters or sizes of both ends of the connecting rods 25 installed in the slots 23 and 24 are different. It may be formed to communicate.

Meanwhile, the first and second slots 23 and 24 are provided with connecting rods 25 having a predetermined length. The connecting rod 25 has both ends 25a and 25b of different shapes, and both ends 25a and 25b are installed to move along the first slot 23 and the second slot 24, respectively.

One end 25b of the connecting rod 25 moving in the second slot 24 is provided with a relaxation means 26 that increases or decreases according to the opening and closing degree of the door body 20. Here, the relieving means 26 may have a variety of forms, it is easy to mount and the most convenient is to apply a spring.

In the case of employing the spring as the relief means 26, it is effective to set the spring to the coil spring to be in the original state when the door body 20 is opened as much as possible. This is because, as the door body 20 is closed, the spring is compressed, and as the spring is compressed, the restoring force to recover to the original state is increased. At this time, since the restoring force acts in a direction opposite to the direction in which the door body 20 is closed, the door body 20 is not closed quickly but is closed slowly, and the door body 20 and the top cover 40 or the casing 10 are closed. ) Can reduce collisions.

Here, the relief means 26 may be formed of an elastic member such as rubber having a sufficient thickness instead of the spring and having an elastic force during compression.

In addition, a fluid cylinder (not shown) may be used as the relief means 26 instead of a spring. That is, the same effect can be obtained by using a fluid cylinder having a damper function in which a piston (not shown) is mounted in a cylinder filled with gas or liquid.

The relief means 26 may be directly installed between the second slot 24 and one end 25b of the connecting rod 25, but one end 25b of the connecting rod 25 located in the second slot 24. ) May be further equipped with a support 27, which is a separate member, and a relieving means 26 may be provided between the support 27 and the second slot 24.

By providing the support 27 at one end 25b of the connecting rod 25, the relief means 26 can be reliably supported, and the support 27 is formed so as to match the size of the second slot 24. One end 25b of the rod 25 can reliably linearly reciprocate in the second slot 24.

In order to install the support 27 on one end 25b of the connecting rod 25, a hole 25d may be formed in the one end of the connecting rod 25b.

That is, the roller 28 may be formed on the outer surface of the door body 20 adjacent to the top cover 40 formed on the upper surface of the casing 10 of the washing machine 1 when the door body 20 is opened. At this time, the roller 28 is mounted to the roller support portion 28a formed in the door body 20.

As the door body 20 is opened or closed, the roller 28 moves along the outer surface of the casing 10 or the top cover 40 of the washing machine 1.

On the other hand, the outer surface of the casing 10 or the top cover 40 in contact with the roller 28 is preferably provided with a curved portion (41). By forming the curved portion 41, the roller 28 may move smoothly, and thus, the opening and closing operation of the door body 20 may be smoothly performed.

It is necessary to limit the maximum opening range of the door body 20. If there is a control panel 30 (refer to FIG. 1) to select the washing operation or the like at the rear of the door body 20 in the opening direction, the door main body 20 and the control panel 30 may collide with each other, causing problems in washing operation. Because there is.

In order to limit the maximum opening range of the door body 20, a stopper 42 is formed in front of the travel direction of the roller 28 when the door body 20 is opened. The position at which the stopper 42 is formed may be sufficient to prevent the door body 20 from colliding with the control panel 30.

On the other hand, if the closing delay means or relaxation means 26 is broken, the door body 20 may be quickly closed or may collide with the casing 10 or the top cover 40, so that the casing (10) Alternatively, the buffer means 60 may be further formed on the top cover 40.

The buffer means 60 is configured to include a door contact member 60a in contact with the door 20 as the door 20 is closed, and an elastic member 60b for supporting the door contact member 60a. In addition, the top cover 40 or the casing 10 may be further formed with a shock absorbing means mounting portion 60c for accommodating the shock absorbing means 60.
