Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing the appearance of the drum-type washing machine 1 according to the first embodiment. FIG. 2 is a front view of the drum type washing machine 1. In the present application, a drum-type washing / drying machine capable of washing and drying and a drum-type washing machine that performs only washing without drying are collectively referred to as a drum-type washing machine 1.

As shown in FIGS. 1 and 2, a door 20 for covering the washing tub is provided on the front surface of the drum type washing machine 1. The door 20 is a round door that matches the shape of the laundry inlet of the washing tub. The door 20 is rotatably supported with respect to the washing machine main body 11 by a hinge (not shown) on either the left or right end side (the left side when viewed from the front in the examples of FIGS. 1 and 2), and the hinge shaft. By rotating in the horizontal direction around it, the laundry inlet is opened and closed. Further, a handle portion 21 for a user to put his / her hand when opening the door 20 is provided on the upper right side when viewed from the front of the door 20.

On the front surface of the drum type washing machine 1, the door 20 does not protrude from the front surface of the washing machine main body 11. Therefore, the front surface of the drum-type washing machine 1 is formed as a gentle surface having no particularly protruding portion, which improves the design of the drum-type washing machine 1. Further, as shown in FIG. 2, the front surface of the drum type washing machine 1 is between a first plane 101 which is a substantially vertical plane, a second plane 102 which is an inclined surface, and a first plane 101 and a second plane 102. It is formed by a variable curved surface 103 that gently connects the above.

As described above, the drum-type washing machine 1 having no unevenness between the front surface of the washing machine main body 11 and the front surface of the door 20 has no fear of being caught by a person, and has higher installability and cleaning property. In particular, if the front surface of the drum-type washing machine 1 is only a vertical surface, the internal visibility of the washing tub is reduced, and if the front surface of the drum-type washing machine 1 is only an inclined surface, the front of the lower part of the washing machine main body 11 is moved to the front. Pop-out increases and installability decreases.

The first flat surface 101 is formed at the lowermost part of the front surface of the drum type washing machine 1 and occupies most (at least half or more) of the front surface of the drum type washing machine 1. The hinge that pivotally supports the door 20 is arranged in the region of the first plane 101 so that the door 20 can be rotated in the horizontal direction.

The second plane 102 is formed on the uppermost portion of the front surface of the drum type washing machine 1, that is, above the first plane 101, and is inclined rearward from the bottom to the top with respect to the first plane 101. .. Normally, the drum-type washing machine 1 installed on the floor is placed at a position lower than the user, so that the second flat surface 102 inclined rearward faces diagonally upward and is located on the front side of the drum-type washing machine 1. It is easy for standing users to see. Therefore, it is preferable that the operation panel portion 31 is formed on the second plane 102. Further, for example, a drawer type detergent charging case 32 may be provided on the second flat surface 102.

The variable curved surface 103 is a curved surface that curves in the vertical direction in order to gently connect the first plane 101 and the second plane 102, and at least a part of the upper portion of the variable curved surface 103 is an inclined surface.

The handle portion 21 is formed on the back surface side from the outer peripheral portion of the door 20, and is designed not to be exposed on the front surface side of the door 20. As a result, the handle portion 21 does not affect the design of the front side of the door 20, and the design of the door 20 can be improved. Further, since there is no unevenness on the front surface of the door 20, the cleanability of the door 20 is improved.

At a position corresponding to the handle portion 21 on the front surface of the washing machine main body 11, a recess 12 formed by being recessed behind the front surface of the door 20 is provided on the outer peripheral side of the handle portion 21. When the user opens the door 20, he / she can insert his / her hand through the recess 12 and put his / her hand on the handle portion 21. Further, by providing the recess 12 on the front surface of the washing machine main body 11, the user can easily recognize the position of the handle portion 21.

In the drum type washing machine 1, the shape of the recess 12 is a substantially arc shape when viewed from the front. In this way, by making the shape of the recess 12 an arc shape close to the state when the user bends his / her finger to grasp the handle portion 21, it becomes easy to guide the user's finger to the handle portion 21. Further, it is possible to prevent the user's finger from locally hitting a portion other than the handle portion 21 during the opening / closing operation of the door 20, so that the door 20 is easy for the user to operate and has high usability.

In the drum-type washing machine 1 according to the first embodiment, the door 20 is arranged at a position where it hangs on all of the second flat surface 102, the variable curved surface 103, and the first flat surface 101. In other words, the door 20 itself is formed so as to include two planes, a first plane 101 (a part) and a second plane 102 (a part). The handle portion 21 is arranged on the inclined surface of the door 20, and at least a part of the handle portion 21 is arranged on the second plane 102. Further, it is more preferable that the handle portion 21 is arranged at a position where it hangs on both the second plane 102 and the variable curved surface 103.

In the drum-type washing machine 1 according to the first embodiment, the door 20 is formed so as to include two planes of the first plane 101 and the second plane 102, and the hinge that pivotally supports the door 20 is a substantially vertical plane. The handle portion 21 is arranged in the region of the first plane 101, and the handle portion 21 is arranged on an inclined surface. By arranging the hinge in the region of the first plane 101, the door 20 rotates in the horizontal direction, and it is possible to suppress the opening and closing of the door 20 from becoming heavy due to the weight of the door 20 itself. Further, by arranging the handle portion 21 on the inclined surface, when the user tries to open the door 20 and reaches out from above the handle portion 21 and pulls the door 20, the direction in which the user pulls the door 20 (obliquely upward). The gripping surface of the handle portion 21 is more likely to be hooked on the user's finger with respect to the direction (assuming the direction). As a result, the user's finger is less likely to slip from the gripping surface of the handle portion 21, and the door 20 can be reliably opened with a lighter force. As a result, the door 20 in the drum-type washing machine 1 becomes highly usable for the user.

Further, in the drum type washing machine 1 according to the first embodiment, by arranging at least a part of the handle portion 21 so as to be located on the variable curved surface 103, the door has a high rigidity of the handle portion 21 while being inexpensive. It can be 20. That is, the door 20 including the two planes (first plane 101 and the second plane 102) has higher rigidity against twisting and bending of the door 20 itself than the door formed by a single plane. Further, the variable curved surface 103 on which the two planes are combined has higher rigidity than the curved surface 103 itself, which is a curved surface. Therefore, by locating at least a part of the handle portion 21 on the variable curved surface 103, it is possible to form the handle portion 21 having high rigidity with a simple structure. Further, since the handle portion 21 has high rigidity, it is not necessary to add a complicated reinforcing structure to the handle portion 21, and the door 20 can be formed at low cost.

In the drum-type washing machine 1 according to the first embodiment, the first plane 101 is a substantially vertical plane, but this is not limited to the form in which the first plane 101 is a vertical plane, and the first plane 101 is not limited to this. Also included is a configuration in which the surface is an inclined surface that inclines backward from the bottom to the top. As a result, even if the drum is arranged so as to be inclined downward toward the rear, the angle difference between the laundry loading port and the drum opening surface can be reduced, so that the user can use the laundry loading port to enter the drum. It makes it easier to see the laundry and improves convenience. In this case, the first plane 101 is preferably set to such an extent that it does not become too heavy due to the weight of the door 20, and is preferably within 10 to 20 ° with respect to the vertical plane, for example. Then, the second plane 102 is tilted so as to face diagonally upward with respect to the first plane 101. As a result, the door 20 can be reliably opened with a lighter force as described above.

[Embodiment 2]
When the user opens the door 20, if the user's hand is wet or the detergent is attached to the hand, it is assumed that the hand slips on the handle portion 21 and it becomes difficult to open the door 20. In the second embodiment, the structure of the handle portion 21 that makes the user's hand less slippery will be described with reference to FIGS. 3 to 5. FIG. 3 is a back view of the door 20. FIG. 4 is an enlarged perspective view of the handle portion 21 as seen from the back surface of the door 20. FIG. 5 is a cross-sectional view of the handle portion 21, and is a cross-sectional view taken along the line AA in FIG.

As shown in FIGS. 3 to 5, a convex portion 22 serving as a burrs is formed on the outer peripheral edge portion of the handle portion 21. In this way, by providing the convex portion 22 that serves as a burrs on the outer peripheral edge portion of the handle portion 21, when the user opens the door 20, the finger catching on the handle portion 21 is improved. As a result, the door 20 can be opened even with a weak grip strength without the hand slipping on the handle portion 21, and the usability of the door 20 is improved.

[Embodiment 3]
