  FIG. 6 is an enlarged view of a main part of the door including the lock mechanism and the lid opening operation part, and shows a connection state between the lock mechanism 600 and the lid opening operation part 800. 7 is a cross-sectional view of the main part in the vicinity of the lid opening operation member, and is a cross-sectional view taken along the line B-B of FIG. 6 including a part of the housing side. Shown in thin lines. FIG. 8 is a cross-sectional view of the main part in the vicinity of the lock mechanism, and is a CC cross section of FIG. When the user opens the door 300, when the handle 810 of the lid opening operation unit 800 is pulled forward of the housing 200, the lid opening operation unit 800 rotates about the rotation shaft 820, and the connecting unit G , The latch 610 is rotated, the engagement with the lock hole 218 is released, and the laundry can be put.

  Hereinafter, FIGS. 6 to 8 will be described in detail. The lock mechanism 600 includes a latch 610 that engages with the lock hole 218, a rotation shaft 620, a latch piece 630 that is formed integrally with the latch 610, and a latch spring 640, and the latch 610 is biased by the latch spring 640. It is provided so that it can rotate. The lid opening operation portion 800 includes a handle portion 810 that is pulled forward by a user when the user opens the door 300, a rotating shaft 820, and a pressing piece 830 that is integrally formed with the handle portion 810. It has and is provided so that rotation is possible. The locking mechanism 600 and the lid opening operation part 800 are configured such that the pressing piece 830 overlaps the latch piece 630 in the connecting part G.

  The outer edge 811 of the handle portion 810 is formed as a concentric circular arc having a diameter larger than that of the circular support frame 320 (cover disk 322), and is provided outside the outer periphery of the support frame 320. FIG. 7 shows a state in which the handle portion 810 is rotated about the rotation shaft 820 with a thin line. Here, if the radius of the outer periphery of the support frame 320 is r1, the radius r2 on the inner side of the outer edge 811 of the handle portion 810 is set larger by a gap of the dimension d provided so as not to interfere with the support frame 320, and r2 = R1 + d.

  In the first embodiment, r1 = 240 mm and d = 10 mm, and the width W of the handle portion 810 is set to 100 mm, which is a dimension that can be sufficiently covered by four fingers of a human hand. In this case, the handle portion 810 is housed in a position that is 10 mm outside the outer periphery of the support frame 320 (cover disk 322) having a diameter of 480 mm so as to have an outer edge 811 having a thickness t and a width W of 100 mm. It can be constructed without significantly affecting the overall design of the 100.

  The handle portion 810 is not so conspicuous in terms of design, and only needs to be easily recognized by the user during use. Therefore, only the outer edge 811 of the handle portion 810 is partially enlarged from the outer periphery of the support frame 320 in the radial direction. By doing so, the washer-dryer 100 with excellent design can be realized without reducing usability. In the vicinity of the lid opening operation portion 800 on the concave surface 216, an enlarged concave portion 217 is formed in the opening frame portion 214 so that a user's hand can enter.

  As shown in FIG. 6, the direction of the tangent S at the center of the outer edge 811 is not parallel to the rotation shaft 820 but forms an angle θ2, and the extension line of the tangent S at the center of the outer edge 811 and the rotation shaft 820 And an extension line of the center line L of the center line L above the lid opening operation unit 800 in the height direction. If the inside of the outer edge 811 is configured to be larger than the outer periphery of the support frame 320 by a dimension d in the radial direction as in the first embodiment, the direction of the tangent at the center position of the outer edge 811 is the width of the handle portion 810. The direction of the tangent at each part of W is averaged. That is, the handle portion 810 is formed in the width direction of the lid opening operation portion 800 near the upper side in the height direction of the housing 200, and is not asymmetrical as in the prior art but asymmetrical. In other words, the handle portion 810 is formed on the upper side in the height direction of the housing 200 in the length direction of the rotational shaft 820 provided obliquely.

The dimension d on the inner side of the outer edge 811 does not have to be constant in the width direction of the handle portion 810. For example, the dimension d goes upward in the height direction in such a manner that the center of the concentric arc is moved. The dimension d may be set larger. If configured in this way, the turning radius from the turning shaft 820 is small, and the clearance margin increases as the upper part easily interferes with the support frame 320 at the time of turning, and it is necessary to take up a little gap at the time of turning. Since there is no gap below the gap, the outer edge 811 can be made inconspicuous in terms of design. The shape of the outer edge 811 is not limited to being concentric with the support frame 320, and may be a combination of arcs or straight lines having different diameters.

  On the other hand, when the user opens the door body 300, it is not necessary to bend the waist as the position of the handle portion 810 is higher, and the user can open the door body 300 easily. However, as shown in FIG. 4 and FIG. 8, during washing with washing water in the rotary drum 112, the window 310 and the seal member 115 prevent water from leaking from the door 300 to the outside of the machine. Must be sealed. The repulsion of the seal member 115 generated over the entire circumference is received by the latch 610 of the lock mechanism 600 being engaged with the lock hole 218 to keep the water seal. For this reason, the position of the latch 610 can hardly be moved from the horizontal center line of the door body 300 (support frame 320), and is almost arranged on the horizontal center line of the door body 300.

  When the handle portion 810 is pulled forward of the housing 200 (see the thin line in FIG. 7), the lid opening operation portion 800 rotates about the rotation shaft 820. At this time, the pressing piece 830 pushes the latch piece 630 at the connecting portion G, and the latch 610 rotates about the rotation shaft 620 to the position shown by the thin line in FIG. 8 to release the engagement state with the lock hole 218. As a result, the door 300 opens. Although it operates in this way, the fact that the position of the latch 610 cannot move from the horizontal center line of the door body 300 means that the connecting portion G cannot move too much in the height direction of the housing 200. Therefore, if the position of the handle portion 810 is moved upward in this state, the lid opening operation portion 800 is increased in size.

  In such a case, the attachment ring 321 to which the lid opening operation unit 800 is rotatably attached has an annular shape, and the following problems are caused in the configuration in which the laundry in the rotary drum 112 can be seen through the translucent cover disk 322. Arise. That is, when the lid opening operation unit 800 is enlarged, the rotation shaft 820 moves inward in the radial direction of the door body 300. As it is, the rotating shaft 820 can be seen from the front through the cover disk 322, and in order not to be seen, the portion protruding from the mounting ring 321 of the rotating shaft 820 must be formed so as to be removed. Don't be. That is, the strength of the lid opening operation unit 800 is reduced.

  The lid opening operation unit 800 needs to efficiently transmit the rotation of the handle 810 to the connecting unit G so that the engagement state of the latch 610 is quickly released, but if the strength is reduced, the rotation angle of the latch 610 is increased. The latch 610 is not released unless the handle 810 is pulled a lot. That is, even if the handle portion 810 is moved upward in order to improve the usability when opening the door body 300, the door body 300 becomes difficult to open in the end, and the usability is not improved.

  Therefore, as shown in FIG. 6, the handle portion 810 is formed asymmetrically in the width direction at the upper side in the height direction of the housing 200 in the longitudinal direction of the rotational shaft 820 provided obliquely, and the outer edge 811. The direction of the tangent line is not parallel to the rotation shaft 820 but forms an angle and intersects above the lid opening operation unit 800 in the height direction of the housing 200. As a result, even if the lid opening operation unit 800 is enlarged by moving the handle 810 upward in the height direction of the housing 200, the rotation shaft 820 is closer to the outer periphery of the support frame 320 as it moves upward. Even if the pivot shaft 820 is formed without being partially removed, the pivot shaft 820 is within the range that cannot be seen through the cover disk 322 from the front, that is, inside the mounting ring 321.

FIG. 7 is a cross-sectional view taken along the line B-B where the rotation shaft 820 is located on the innermost side in the radial direction from the outer periphery. However, since the rotation shaft 820 is housed inside the mounting ring 321, the rotation shaft 820 is It is formed without being removed, and the strength of the lid opening operation portion 800 is improved. Even if the size of the lid opening operation unit 800 is increased by moving the position of the handle unit 810 upward, the strength of the lid opening operation unit 800 tends to decrease. However, the handle unit 810 is formed asymmetrically, and the handle unit 810 is formed. Since the tangential direction of the outer edge 811 forms an angle with the rotation shaft 820, a sufficient strength is ensured without the need to add a reinforcing member such as a sheet metal. Then, the rotation when the user pulls the handle portion 810 is efficiently transmitted to the connecting portion G, the engagement of the lock mechanism 600 is quickly released, the door body 300 can be easily opened and closed, and the user can The operability when opening the door 300 is improved, and the usability is improved.

  In the first embodiment, as shown in FIG. 6, the handle portion 810 is partially provided at an asymmetrical position closer to the upper side than the width direction of the lid opening operation portion 800. For example, the width W of the handle portion 810 is about 100 mm into which four fingers can sufficiently enter, the total width of the lid opening operation portion 800 is about 200 mm, which is twice that width, and the position of the handle portion 810 is above the height direction of the casing 200. It is provided at an asymmetrical position. The angle (tilt from the horizontal) of the handle 810 with respect to the horizontal center line of the support frame 320 of the handle 810 is set to 45 °. Since the pressing piece 830 that transmits the rotation of the handle 810 to the latch 610 cannot move the position of the latch 610 from the center line of the door body 300, it is positioned at the lower end opposite to the handle 810. Note that the width W of the handle portion 810 is set to about 100 mm where four fingers can sufficiently enter, but this is set so as to be easier to use and does not necessarily require sufficient insertion of four fingers. However, it may be set smaller as long as there is no unreasonableness.

  According to the configuration described above, the lid opening operation unit 800 is enlarged, but the handle unit 810 remains the size necessary for hooking a finger, and only the position is higher than the height direction of the housing 200. Placed in. The handle portion 810 may extend downward and be formed in the same size as the lid opening operation portion 800. However, when the outer edge 811 of the handle portion 810 that protrudes radially outward from the outer periphery of the support frame 320 is similarly increased. It becomes more conspicuous, and the influence on the overall design of the washing / drying machine 100 is increased. Therefore, after the size of the handle portion 810 is limited to the required size for ease of use and design is ensured, the handle portion 810 does not need to bend its waist greatly when opening the door body 300. The operability when the user opens the door 300 is improved by being arranged above the height direction of the housing 200 so that the angle θ1 with the horizontal center line is about 45 °. Usability is also improved.

  The present invention is suitably used for a washing machine, a dryer, and a laundry dryer.
