Field of the Invention The present invention relates to a dishwasher for washing dishes and the like, and more particularly to an opening and closing mechanism for a door. n first > rhyme and old K standard Background Art A conventional dishwasher can be described below using Fig. 4 . In the dishwasher, the object to be washed, such as tableware, is stored in the washing tank 1. The upper door body (hereinafter referred to as a "squat door body" 3 and the lower door body (hereinafter referred to as a door body) 4 are closed and washed. After the groove [the front surface opening portion (hereinafter referred to as the opening portion) 2, the cleaning pump (not shown) is started. The washed and rinsed steps are carried out by spraying the washing water. Opening and closing The door opening and closing form of the front opening portion 2 has various forms. In the dishwasher, the door body is divided into two door bodies 3, 4. This makes it possible to reduce the space necessary for opening and closing the door 15 (the space in which the door moves). Therefore, the setting property can be improved, and the dishwasher can be provided in a narrow place. The door body 4 is pivoted downward from the front surface of the front opening portion 2 with the fulcrum 5 as the center. On the other hand, the door body 3 is supported by the rotation of the fulcrum 6, and is open to the space above the body. Therefore, the height necessary for opening and closing the door body 3 is suppressed to be small, 20 so that the dishwasher can be provided at a lower height. At the same time, when the door body is completely opened, the protruding length of the door body 3 toward the front of the opening portion 2 is reduced, so that there is no obstacle when the loaded object is taken out and loaded. An example of such a dishwasher is disclosed in Japanese Laid-Open Patent Publication No. 2002-272660. However, the opening and closing structure of the door body above the conventional dishwasher has the same height and the size required to open and close the upper door body 3 when the body is the same as the shape and size of the door body, and the door body 3 protrudes forward when the % is completely open. The length has the opposite relationship. Therefore, if the opening and closing height is lowered, the length protruding forward is increased, and if the length protruding forward is shortened, the opening and closing height is increased. In particular, when the length of the door body 3 becomes large, even if the opening and closing height of the door body 3 does not change, the door body 3 protrudes forward, which causes inconvenience in use. [In the examination of the invention] The dishwasher of the present invention includes a body, and is provided with an opening; 10 a washing tank is provided in the body; and the door body covers the opening and can be opened and closed freely And a sliding groove extending in a downward direction in a closed state; a sliding support portion, wherein one end is supported by the upper portion of the outer wall of the cleaning tank and is rotatable, and the other end supports the door body and is in the sliding groove And the movement restricting portion, wherein one end is held by the outer wall of the cleaning tank 15 and is rotatable, and the other end is fixed to the door body, so that the door φ body moves and opens on a predetermined track. In this configuration, the door body is not opened and closed by a single rotation operation, but is opened and closed by a combination of the sliding support portion and the motion-restricting portion. Therefore, when the size of the door body is substantially the same as that of the conventional one, and the height 20 necessary for opening and closing the door body in the fully open state is the same as the conventional one, the length of the door body protruding forward can be shortened. Further, when the length of the door body protruding forward is the same as the conventional one, the height necessary for opening and closing the door body is lowered, so that the setting property of the body can be increased. In addition, since the sliding support portion is supported by the upper portion of the outer wall of the cleaning tank, when the door body moves over the body, the position of the top surface of the body can be accurately adjusted to be d: 6.1291339.

When the switch 27 is pressed, the lock device is released through the engaging portion 29. By the use of the bombs, the interlocking state gives the door body 1 (), and the opening and closing motion potential energy, so that the door body 10'11 automatically opens from the fully closed state to the fully open state in contact with the braking portion 41. The lower end of the open operation is as follows: the center is forward ^>r;f, the square is rotated, and it is condensed to the inner side of the skin. The door body 1() is moved by the execution of the branch 2. For example, ☆ at, ,, the mouth has a yoke and a slip fork. One end side of the crucible 12 is held by the 20 Ϊ 291339 of the washing tank 8 and is rotatable freely, and the other end side is slid by the groove 14 (4) The simple coffee in the structure is: The degree of freedom is higher than the private trajectory. However, by simply sliding the support portion I2, it is not possible to determine that there is a unique trajectory, and it is free to move, and is equal to the top surface of the body. Therefore, the restricting portions 18 and 19 restrict the door body 1〇 to only have a movement trajectory. As a result, the upper space of the wheel shank 10 15 of the upper door body body 7 can be suppressed by the height of the upper door body 10 to be opened and closed = lower one to obtain a dishwasher having good setability. Further, the support portion 12 is provided on the upper portion of the cleaning tank 8 (four), and the body 7 is at the top of the body 7 to achieve a positional relationship between the body 10 and the top surface of the body 7 with high precision. Therefore, the body 10 can be opened and closed on the upper side of the body 7, without being in contact with the cabinet or the like. θ One coin a Further 'In the state in which the carcass 1G is completely open, the protruding length of the door body 1 () protruding to the front of the opening portion 9 is also reduced. Therefore, it is possible to obtain a meal and a washing machine which are easy to see inside the washing tank 8 and which do not interfere with the appearance of the tableware or the like. In this way, the door body 10 is not opened and closed by a simple rotation operation, but the miscellaneous support portion 12 and the movement restricting portions 18, 19 are combined with rotation and sliding: the operation is performed to open the door. Therefore, the size of the door body 1 is substantially the same as that of the conventional one, and when the height required for opening and closing the door body 1 in the fully open state is the same as that of the conventional one, the protruding length of the door body 10 toward the front is shortened. Further, when the length of the door body 1〇 is toward the moon; the length of the protrusion is the same as that of the conventional one, the degree of the opening required for opening and closing the door body lQ is lowered, and the setting force of the body σ is increased. In addition, by setting the support unit to 11.1291339. Next, the cutlery basket is stored in the washing tub 8, and the user closes the door body 11. Since the door body 10 and the door body 11 are opened and closed in conjunction with the interlocking portion 31, the upper door body 10 is also closed at the same time. At this time, the restriction portions 18 and 19 are housed in the storage opening 22 in conjunction with the door body 5, but the user's consciousness may not pay attention to the storage opening 22 due to the interlocking operation with the door body 11. However, in the present embodiment, since the restricting portions 18 and 19 are formed of a resin, even if a part of the user's body, such as a finger, comes into contact with the user, it is not injured. Further, the restricting portion 40 restricts the movement of the door body 1 in the vertical direction, and the abutting portion 24 restricts the movement of the door body 1 to the rear. The engaging portion 15 is not fitted into the groove 14, and can be maintained. The door is stably closed. Further, the connection point 32 is constituted by the rotation axis i8a and the long hole 31a, and the spring 38 gives the restriction portion 18 a potential energy for moving the door body 1 in the closing direction. Therefore, when the door bodies 10 and 11 are nearly completely closed, the door body 10 is surely completely closed 15 first, and the door body 11 is surely pressed against the sealing member 3〇 provided on the door body 10, and the door body 10 is surely performed. 11 sealed. The gap between the groove 14 and the engaging portion 15 is set to be narrowed only when the door body 1 is completely closed. Therefore, the position of the door body 1 is stabilized at the time of closing, and the sealing between the door body 10 and the opening portion 9 is surely performed. Further, the groove 14 and the engaging portion 20 are smoothly slid during the opening and closing, so that the opening and closing operation of the door body can be stably performed. Further, by using the roller 16 at the engaging portion 15, the sliding resistance of the groove 14 and the engaging portion 15 is reduced, and the door body can be more stably opened and closed. The opening and closing of the π door body 10 can be realized without using the restricting portion 19, and the fixing portion 21 of the door and the door body 10 directly supports the restricting portion 1 § and can be rotated freely, and can also be realized by 8 13 -1291339. The storage opening 22 is significantly increased. However, in the present embodiment, the restricting portion 19 is provided, and even when the door body 10 is completely opened, the restricting portion 18 is extended substantially in a V shape downward. Thereby, the size of the storage opening 22 can be kept to a minimum. That is, the door frame strength of the dishwasher can be greatly improved as compared with the structure of the motion restricting portion composed of a single component. Moreover, the positions of the fulcrums of the connecting rod are not easily displaced, and the door body 1 〇, u can be stably opened and closed, and the sealing property is sure. Further, the link mechanisms for opening and closing the door bodies 10 and 11 are provided on the right and left sides of the washing tank 8 and the door bodies 1 and 11. Further, the present invention is not limited by the embodiment. 10 Industrial Applicability The dishwasher of the present invention can improve the installability of the body by reducing the space or height required for opening and closing the door. Further, since the door body can be largely opened from the opening portion to a position where it does not interfere, the convenience of using the object 4 is improved. Further, since the sliding support portion is supported by the upper portion of the wall 15 of the cleaning tank, it is possible to achieve a positional relationship between the top surface of the body and the surface of the body when the door body moves upward. Therefore, when the door body is opened and closed, the shell can be opened and closed smoothly without coming into contact with the top surface of the body or the hanging cabinet. Such a configuration can be widely applied to various machines and devices having an opening and closing door for taking out/putting articles. 20 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view showing a dishwasher in accordance with an embodiment of the present invention. Figure 2 is a perspective view of the dishwasher shown in Figure 1. Figure 3 is a perspective view of the important part of the dishwasher above the door when it is fully opened. 8 14
