Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure of a dishwasher incorporated in a system kitchen, and more particularly, a face material attached to a front portion of the door is parallel to the front through a movable mechanism as the door rotates. The present invention relates to a door structure of a dishwasher that is pushed out separately.

[0002]

2. Description of the Related Art Conventionally, the door of a dishwasher incorporated in a system kitchen is generally opened by grasping an upper handle portion and pulling it toward you. In addition, the face material attached to the front part is matched with the design color of the front of the system kitchen, and the entire color is unified to improve the appearance design.

By the way, since the height dimension of the system kitchen varies depending on the model, it is necessary to mount the face material of the front surface of the door having the height dimension corresponding thereto. However, when the face material attached to the front surface is long and protrudes downward with respect to the door base of the door body of a certain size, when the door is opened and closed, the lower end of the face material is the dishwasher body. Since it interferes with the lower riser, it cannot be rotated. Therefore, in this case, it is possible to deal with this by escaping the portion that interferes with the lower end of the face material of the dishwasher main body to the inside, but this is not preferable because the storage capacity of the dishwasher main body is reduced. Therefore, it has been dealt with by dividing the surface material into two parts, that is, a part that is opened and closed together with the door base and a part that is joined to the lower part and fixed to the lower part of the dishwasher body. However, in this case, by dividing the face material into two parts, the horizontal boundary line formed by dividing the face material into only the front part of the dishwasher, which spoils the appearance design of the entire system kitchen. ..

In order to solve this, therefore, the face member attached to the front surface of the door base is pushed out in parallel forward through the movable mechanism as the door rotates, so that the lower end portion becomes the riser portion. There is one that avoids interference so that the door can be opened and closed smoothly without dividing into two. FIG. 3 is a side view showing a door structure of a conventional dishwasher in which a face material can be pushed forward and separated. In the figure, 1 is a dishwasher main body incorporated in the system kitchen, 2 is a dishwasher main body 1
, 3 is a door base portion that constitutes the main body of the door, 4 is an operation portion disposed on the upper portion of the door base portion 3, and 5 is a face material such as a decorative plywood attached to the front surface portion of the door base portion 3, Corresponding to the height of the system kitchen, it is longer than the door base 3 and protrudes downward. The appearance color of the face material 5 is unified with the appearance color of other drawers, storage boxes, etc. of the system kitchen. Reference numeral 6 is a parallel link provided between the door base 3 and the face member 5. Normally, the face member 5 is pressed against the front face of the door base 3 by the pulling force of the tension coil spring 6d and is in contact with the face member 5. keeping. Reference numeral 7 is a spacer attached to the lower side of the operation unit 4 in order to improve the appearance of the front part of the dishwasher. Reference numeral 8 denotes a riser which is inclined from the upper side toward the inner side in the lower portion of the front surface of the dishwasher main body 1.

Next, the operation of the door structure of the conventional dishwasher will be described. In the use of the dishwasher, when the handle (not shown) on the upper portion of the door 2 is grasped and pulled toward the front side, the door base portion 3 rotates forward about the fulcrum 3a at the lower end portion. On the other hand, the face material 5 starts to rotate forward with the rotation of the door 2 similarly to the door base portion 3, but since the lower end portion thereof projects downwardly for a long time, its inner surface is the upper end of the riser portion 8. When the door 2 comes into contact with the corner portion and further rotates the door 2, the door portion 3 is pressed against the corner portion and resists the tensile force of the tension coil spring 6d.
In parallel with the above, they are separated and pushed forward in the forward direction.
Then, when the position exceeds the position parallel to the inclination angle of the riser portion 8, the face material 5 in turn becomes the lower end corner portion 5 inside the lower end surface.
At b, it contacts the inclined surface of the riser 8 and receives a reaction force from this contact. In this state, the door 2 continues
When the door 2 is opened, the distance between the parallel links 6 is further expanded, and when the door 2 is completely opened, the face material 5 reaches the lowermost position in the figure and is in a state substantially parallel to the floor surface. In this lowest position,
A hooking mechanism (not shown) works on the parallel link 6, and the face member 5 is held at this position.

That is, when the door 2 having the above structure is rotated forward, the lower end portion comes into contact with the riser portion 8. However, the elastic force of the tension coil spring 6d of the parallel link 6 causes the face material 5 to move forward. Therefore, even if the face material 5 is long, the door 2 can be opened and closed without being divided into two.

[0007]

Since the door structure of the conventional dishwasher is constructed as described above, the handle of the upper part of the door 2 is pulled so that the face material 5 is separated from the door base 3 forward. At the time of starting, the parallel links 6 move upward while being separated from each other, so that the space s between the lower surface of the spacer 7 attached to the lower side of the operating portion 4 and the upper surface of the surface member 5 is small. Then, the upper end corner portion 5a inside the upper end surface of the face material 5 interferes with the lower surface of the spacer 7. This phenomenon also occurs when the door 2 is closed. Therefore, the lower surface of the spacer 7 and the face material 5
The gap s from the upper end surface of the must be set large. As a result, the door base 3 on the back side of the face material 5 was visually recognized from the gap s, and the appearance quality was deteriorated.

On the other hand, when the door 2 is opened, the face material 5 is pushed forward by the lower end corner portion 5b inside the lower end surface receiving the reaction force from the riser portion 8, but at this time, the lower end corner Since the portion 5b is formed at an acute angle, the sliding of the abutting portion is bad and the door 2 cannot be smoothly rotated. Further, scratches were generated on the contact portion of the riser portion 8.

Therefore, according to the present invention, the face material can be extruded forward through the movable mechanism, the gap formed between the face material and the upper adjacent member can be reduced, and smooth opening and closing can be performed. An object of the present invention is to provide a door structure for a dishwasher that can prevent damage to the contact portion of the riser with the lower end of the face material.

[0010]

A door structure for a dishwasher according to the present invention is mounted on a door base and a front surface of the door base, and is pushed forward in parallel with a rotation of the door via a movable mechanism. In a door structure of a dishwasher including a face material, a chamfering process is applied to a portion of an upper end corner portion of the face material that avoids interference with an upper adjacent member, and / or a lower end corner of the face material. The chamfering process of the curved surface is applied to the part of the part that contacts the riser part.

[0011]

In the present invention, since the upper end corner portion of the face material is chamfered, interference with the upper adjacent member can be avoided when opening and closing the door, and the face material and the upper adjacent member can be prevented. The gap can be reduced. In addition, since the lower end corners of the face material are curved to make a chamfer, when the door is opened and closed, the contact between the lower end corner and the riser will slide smoothly, opening and closing the door smoothly. In addition, it is possible to prevent abrasion of the contact portion of the riser portion.
