Description

Clothes treatment device

technical field

The present invention relates to a clothes treating device that includes a door that closes or opens an opening for taking out and putting in clothes, and that performs at least one of washing and drying.

Background technique

A washing and drying machine has been proposed as a conventional laundry treatment device (for example, refer to JP-A-2012-11090).

9 is a perspective view of a conventional washing and drying machine 100 , and FIG. 10 is an enlarged rear view showing main parts of the washing and drying machine 100 including a locking mechanism 600 and a door 300 including a door 300 . In addition, FIG. 10 shows a schematic structure of the handle portion 710 of the door body 300 and the lock mechanism 600 . In addition, FIG. 11 is a main part cross-sectional view showing the structure of the conventional washing and drying machine 100 near the lid opening operation part 700 .

The washing and drying machine 100 includes a rotary drum for accommodating laundry in the casing 200 and an opening 215 on the front surface. In addition, the washing and drying machine 100 includes a door body 300 . The door body 300 is attached to the casing 200 so as to be rotatable between a closed position for closing the opening 215 and an open position for opening the opening 215 .

Around the opening 215 of the housing 200 is formed a concave region 216 , which is formed with a recess toward the inside of the housing 200 . The door body 300 rotated to the closed position is received in the recessed area 216 . When the door 300 is in the closed position, the inner surface of the door 300 facing the opening 215 and the concave region 216 surrounding the opening 215 has a shape that bulges toward the center of the door 300 .

The inner surface of the door body 300 is crimped to the watertight seal member 115 disposed inside the housing 200 by using the concave region 216 of the housing 200 and the raised shape of the inner surface of the door body 300 . In this way, a watertight sealing structure is formed between the door body 300 and the washing tub.

When putting in laundry, the user pulls the handle portion 710 of the cover opening operation portion 700 provided on the door body 300 . As a result, the latch 610 of the lock mechanism 600 is rotated to release the engagement with the lock hole 218 of the housing 200 , so that the door 300 can be opened.

In the conventional washing and drying machine 100, as shown in FIG. 10, the opening operation part 700 is provided in the position separated from the lock mechanism 600 but relatively close. The opening operation part 700 is configured to transmit the rotation of the opening operation part 700 to the rotation of the latch 610 of the lock mechanism 600 through the coupling part G. As shown in FIG.

In addition, in order to correspond to the design when opening and closing the door body 300 from left and right directions, the opening operation part 700 is formed to be bilaterally symmetrical in its width direction (W direction), and the width of the handle part 710 is formed to be the same as that of the opening. The substantially entire width of the cover operation part 700 is close to the width.

In the conventional washing and drying machine 100, the rotation axis of the rotary drum is horizontal or inclined downward from the front to the rear. Therefore, when the position of the handle portion 710 is located above the height direction of the housing 200 compared to the center line of the door body 300 in the horizontal direction, the user does not need to bend down greatly when opening the door body 300 . Operability is improved.

On the other hand, in order to effectively prevent water leakage during operation, the lock mechanism 600 needs to be disposed on the approximate center line of the door body 300 in the horizontal direction. However, in the case of using a structure in which the rotation of the handle part 710 is transmitted to the rotation of the latch 610 of the lock mechanism 600 through the link G, it is difficult to largely separate the handle part 710 from the lock mechanism 600 regardless of the position of the handle part 710. Both go lower.

Here, when the handle portion 710 is intended to be disposed above the housing 200 in the height direction to improve operability when the user opens the door body 300 , the handle portion 710 is away from the locking mechanism 600 . In this case, in addition to the structure in which the rotation of the handle part 710 is transmitted to the rotation of the latch 610 of the lock mechanism 600 through the connection part G, the opening operation part 700 forming the handle part 710 and the connection part G is enlarged, Difficult to secure strength. If the strength of the opening operation part 700 is insufficient, even if the user pulls the handle part 710 of the opening operation part 700, the coupling part G and the latch 610 cannot be rotated sufficiently due to the deformation of the opening operation part 700, thereby It is difficult to open the door body 300 .

That is, when it is desired to arrange the handle portion 710 substantially symmetrically in the width direction of the entire width of the lid opening operation portion 700 without enlarging the lid opening operation portion 700, as shown in FIG. 10 , the handle portion 710 It can be arranged only above the angle θ1 with the horizontal center line of the door body 300 of about 20°. In this position, the user has to bend down greatly when opening the door body 300, so it is not easy to say that the operability when opening the door body 300 is good, resulting in slightly poor usability.

In addition, in order to arrange the position of the handle part 710 upward, instead of enlarging the opening operation part 700, it is conceivable to extend the lock mechanism 600 upward. However, in this case, the position of the latch 610 needs to be radially inward compared with the outer periphery of the door body 300, and there is a problem that the opening 215 for taking out and putting in clothes becomes smaller, resulting in poor usability. The problem. In addition, the angle formed by the rotation axis of the latch 600 and the rotation axis of the opening operation part 700 becomes large, so when the rotation of the handle part 710 is transmitted to the rotation of the latch 610 by the connection part G, it is difficult to transmit it efficiently, resulting in Ease of use deteriorates.

Contents of the invention

The present invention is made in view of the above problems, and provides a clothes processing device that can ensure the strength of the opening operation part, and can move the position of the handle part upward in the height direction of the casing and improve the safety when opening the door body. operability.

The clothes treating device of the present invention includes: a casing having an opening for taking out and putting in clothes; and a door for opening and closing the opening. The door body has a supporting frame, and a hinge structure, a locking mechanism, and a cover opening operation part are arranged on the supporting frame. The cover opening operation part has a handle part and a rotation shaft, and is used for unlocking the locking mechanism. The handle portion is formed at a position close to the upper side in the height direction of the casing in the width direction of the opening operation portion.

And the motor 29, the water supply system 37, the drainage system 38, and the drying system 39 are automatically controlled by the control circuit part 43 according to a mode setting and a control program. Thereby, a washing process, a rinsing process, a dehydration process, and a drying process are performed.

As schematically shown in FIGS. 1 and 2 , the washing and drying machine 50 includes a locking mechanism 47 that locks the door body 11 at the closed position. The control circuit portion 43 is used as a control portion that controls a lock control unit that locks the door body 11 at the closed position in cooperation with the lock mechanism 47 .

As shown in FIG. 4 , the water supply system 37 includes a water supply pipe 48 connected to the water tank 27 and a detergent container 49 for storing detergent. In addition, as shown in FIG. 1 , a cover 51 for closing the detergent container 49 is attached to the top wall 17 of the casing 12 .

The water supply system 37 can timely supply water to the water tank 27 through the water supply pipe 48 by opening and closing the solenoid valve (see the solid arrow in FIG. 4 ). In addition, the washing and drying machine 50 can timely inject the detergent in the detergent container 49 disposed so as to partially cross the water supply pipe 48 into the water tank 27 by using the water supplied by the water supply system 37 .

The drainage system 38 includes: a first pipeline 52, which is provided with one end connected to the discharge port 35 of the water tank 27; a drainage control unit 53, which is connected with the other end of the first pipeline 52, and receives washing from the water tank 27; and the second pipe 55 extending between the circulation pump 54 included in the drainage control unit 53 and the water tank 27 .

Thereby, the lock mechanism 47 is released, the door body 11 is opened, and the door body 11 can rotate between a closed position and an open position. A substantially rectangular locking hole 61 and a detection hole 62 are formed on the concave surface 23 of the housing 12 . In addition, near the opening operation portion 59 of the concave surface 23 , an enlarged concave portion 63 is formed in the opening frame portion 22 to allow the user's hand to enter.

5A is a diagram showing a schematic cross-sectional structure of the door body 11 according to the embodiment of the present invention, and FIG. 5B is a rear view of the door body 11 . In addition, FIG. 5A is a cross-sectional view of line segment 5A-5A of FIG. 5B including a part of the structure on the housing 12 side.

In addition to FIG. 5A and FIG. 5B , the structure of the door body 11 will be described while referring to FIG. 1 as necessary. As described above, the door body 11 includes the window portion 32 and the support frame 33 . The window portion 32 is made of glass and formed in a substantially trapezoidal conical shape. When the door body 11 is rotated to the closed position, the window portion 32 is first inserted into the opening portion 24 (see FIG. 1 ). The substantially annular inclined wall 66 extending from the substantially circular starting wall 64 toward the edge portion 65 abuts on the sealing member 31 as described above (see FIG. 4 ).

The support frame 33 includes: a substantially ring-shaped mounting ring 67 , a substantially disc-shaped translucent cover plate 68 covering the mounting ring 67 from the outside, and a substantially ring-shaped pressing ring 69 disposed inside. The surface of the cover plate 68 has a curved surface substantially continuous with the curved main wall 20, and is curved along the main wall 20, so that it is excellent in cleaning performance. In addition to the window portion 32 , the opening operation portion 59 , the lock mechanism 47 , and the hinge structure 26 are attached to the attachment ring 67 .

As shown in FIG. 5B , the hinge structure 26 and the lock mechanism 47 are disposed on a substantially horizontal line passing through the center of the door 11 as seen from the front at both ends of the door 11 . As shown in FIG. 1 and FIG. 5B , the hinge structure 26 and the lock mechanism 47 are disposed at substantially both ends of the door body 11 . The opening operation part 59 is disposed adjacent to the lock mechanism 47 above the lock mechanism 47 . The mounting ring 67 and the pressing ring 69 are used as supporting parts for supporting the handle part 60 , the locking mechanism 47 and the hinge structure 26 .

Fig. 6 is an enlarged view of main parts of door body 11 including lock mechanism 47 and cover opening operation part 59 of washing and drying machine 50 according to the embodiment of the present invention. FIG. 6 shows the connection state of the lock mechanism 47 and the opening operation part 59 . Moreover, FIG. 7 is a figure which shows the main part cross-sectional structure of the vicinity of the opening operation part 59 of the washing-drying machine 50 which concerns on embodiment of this invention. FIG. 7 is a cross-sectional view along line 7-7 in FIG. 6 including a part of the structure on the housing 12 side, and a state in which the handle portion 60 rotates around the rotation shaft 70 is shown by a dashed-dotted line. Fig. 8 is a diagram showing a cross-sectional structure of main parts in the vicinity of lock mechanism 47 of washing and drying machine 50 according to the embodiment of the present invention. FIG. 8 is a cross-sectional view along line 8-8 of FIG. 6 including a part of the structure on the housing 12 side.

When the user opens the door body 11 , the handle portion 60 of the cover opening operation portion 59 is pulled toward the front of the casing 12 . Then, the opening operation part 59 rotates about the rotation shaft 70, rotates the latch 71 via the connection part G, and disengages with the lock hole 61, and a user can put in laundry.

Next, a more detailed description will be given based on FIGS. 6 to 8 . The locking mechanism 47 has a latch 71 engaged with the locking hole 61 , a rotating shaft 70 , a latch piece 72 integrally formed with the latch 71 , and a latch spring 73 . The latch 71 is biased by a latch spring 73 to be rotatable. The cover opening operation part 59 is configured to have a handle part 60, a rotating shaft 70, and a pressing piece 74 integrally formed with the handle part 60. The cover opening operation part 59 can rotate, wherein the handle part 60 is used for opening the door body 11 by the user. Hook your fingers and pull forward. The locking mechanism 47 and the opening operation part 59 are configured so that the pressing piece 74 is superimposed on the latching piece 72 at the connection part G. As shown in FIG.

The outer edge 75 of the handle portion 60 is formed as a concentric circular arc having a larger diameter than the circular support frame 33 (cover plate 68 ), and is provided outside the outer periphery of the support frame 33 . FIG. 7 shows a state in which the handle portion 60 rotates around the rotation shaft 70 by dotted lines. Here, if r1 is the radius of the outer circumference of the support frame 33, the radius r2 inside the outer edge 75 of the handle 60 is set to be larger than the radius r1 by a gap of d, and r2=r1+d. The gap of dimension d is provided in order to avoid interference with the support frame 33 .

In this embodiment, r1 = 240 mm, d = 10 mm, and the width W (see FIG. 6 ) of the handle portion 60 is set to 100 mm, which is a size sufficient to catch four fingers of a person. In this way, the handle portion 60 is accommodated in a position 10 mm outside the outer periphery of the supporting frame 33 (cover plate 68 ) having a thickness t and a width W of 100 mm at a position 10 mm outside with a diameter of 480 mm. Accordingly, the handle portion 60 can be configured without greatly affecting the overall appearance of the washing and drying machine 50 .

The handle portion 60 is designed not to be too conspicuous, as long as it can be easily recognized by the user during use. In this embodiment, only the outer edge 75 of the handle part 60 is partially enlarged in the radial direction compared with the outer periphery of the support frame 33, so that the washing and drying machine 50 with good design can be realized without reducing usability. In addition, near the opening operation portion 59 of the concave surface 23 , an enlarged concave portion 63 is formed in the opening frame portion 22 to allow the user's hand to enter.

In addition, as shown in FIG. 6 , the direction of the tangent line S at the central portion of the outer edge 75 is not parallel to the direction of the rotation axis 70 but forms an angle θ2. The extension of the tangent S at the central portion of the outer edge 75 intersects the extension of the center line L of the rotation shaft 70 above the opening operation portion 59 in the height direction. If the inner side of the outer edge 75 is configured to have a dimension d larger in the radial direction than the outer periphery of the support frame 33 as in the present embodiment, the direction of the tangent at the central position of the outer edge 75 is the width W of the handle portion 60 The direction obtained by averaging the direction of the tangent of each part. That is, the handle portion 60 is formed above the case 12 in the width direction (W direction) of the cover opening operation portion 59 in the height direction. In addition, the handle portion 60 is not a conventional symmetrical shape, but is formed asymmetrically in the width direction of the opening operation portion 59 . In other words, the handle portion 60 is formed above the case 12 in the height direction in the cover opening operation portion 59 in the longitudinal direction of the obliquely provided rotation shaft 70 .

In addition, the dimension d related to the inner side of the outer edge 75 may not be fixed in the width direction of the handle portion 60 . For example, in a state where the center of the arc of the concentric circles is moved, the dimension d may be increased as it goes upward in the height direction. According to this structure, the radius of rotation from the rotating shaft 70 is small, and the margin of the upper gap that tends to interfere with the support frame 33 when rotating tends to increase. On the other hand, it is less necessary to leave a gap when rotating. The lower gap is narrowed, and the outer edge 75 is not easy to be conspicuous in design. In addition, the shape of the outer edge 75 is not limited to a shape concentric with the support frame 33, and may be formed by a combination of arcs and straight lines with different center positions.

When the user opens the door body 11 , the higher the position of the handle portion 60 is, the less it is necessary to bend down greatly, so the door body 11 can be opened comfortably. However, as shown in FIG. 4 and FIG. 8, in the washing of the state where washing water is poured into the rotary drum 28, in order to prevent the washing water from leaking from the door body 11 to the outside of the machine, it is necessary to use the window portion 32 and the sealing member 31 to carry out uncontrolled cleaning. Water-permeable seal. At this time, by engaging the latch 71 of the lock mechanism 47 with the lock hole 61 , the rebound of the seal member 31 that occurs over the entire circumference is prevented, thereby ensuring a watertight seal. Therefore, the position of the latch 71 can hardly be moved with respect to the horizontal centerline of the door body 11 (support frame 33 ), and the latch 71 is arranged almost on the horizontal centerline of the door body 11 .

When the handle portion 60 is pulled to the front of the housing 12 (see the dotted line in FIG. 7 ), the cover opening operation portion 59 rotates around the rotation shaft 70 . At this time, the pressing piece 74 presses the latch piece 72 at the connecting portion G, and the latch 71 is rotated around the rotating shaft 76 to the position indicated by the dotted line in FIG. 8 to release the engagement with the locking hole 61. state, so that the door body 11 is opened.

The opening operation part 59 of this embodiment operates as described above, and the position of the latch 71 cannot move relative to the horizontal centerline of the door body 11, which means that the connecting part G can hardly move upward in the height direction of the casing 12. . Therefore, if the position of the handle portion 60 is moved upward while maintaining a widthwise symmetrical shape (maintaining the shape shown in FIG. 10 ) in this state, the opening operation portion 59 will increase in size.

In this case, since the mounting ring 67 to which the cover opening operation unit 59 is rotatably mounted is ring-shaped, and the laundry in the rotary drum 28 can be seen through the translucent cover plate 68, the following problems may arise. . That is, when the cover opening operation portion 59 is enlarged, the rotation shaft 70 moves radially inward of the door body 11 , and in this state, the rotation shaft 70 can be seen from the front through the cover plate 68 . In order to prevent the rotation shaft 70 from being seen, it is necessary to adopt a structure in which the portion of the rotation shaft 70 exposed from the mounting ring 67 is cut out. According to such a structure, the strength of the opening operation part 59 will fall.

It is necessary for the opening operation part 59 to efficiently transmit the rotation of the handle part 60 to the connection part G to release the engaged state of the latch 71 as soon as possible. However, if the strength of the opening operation portion 59 decreases, the rotation angle of the latch 71 decreases, and the engaged state of the latch 71 cannot be released unless the handle portion 60 is largely pulled. That is, although the handle portion 60 is moved upward in order to improve the usability when opening the door body 11, the result is that it is difficult to open the door body 11 without improving usability.

Therefore, in the present embodiment, as shown in FIG. 6 , the handle portion 60 is located above the opening operation portion 59 in the height direction of the casing 12 in the length direction of the obliquely arranged rotating shaft 70 and in the width direction. It is formed in an asymmetric manner in the direction (W direction). In addition, be made as following structure: the direction of the tangent line S of the center portion of the outer edge 75 is not parallel to the rotation axis 70 but forms an angle θ2, and the tangent line S of the center portion of the outer edge 75 and the center line L of the rotation axis 70 are closer than the open cover. The upper portion in the height direction of the case 12 where the operation portion 59 is taller intersects. According to this structure, the handle portion 60 can be moved upward in the height direction of the casing 12. Even if the cover opening operation portion 59 is enlarged, the rotating shaft 70 will be closer to the outer periphery of the support frame 33 as it goes upward, so there is no need to partially dig the handle portion 60. Except for the rotating shaft 70, the rotating shaft 70 can be accommodated in a range that cannot be seen through the cover plate 68 from the front, that is, it can be accommodated inside the mounting ring 67.

7 is a cross-sectional view of the rotating shaft 70 at the innermost position in the radial direction away from the outer periphery. In this case, the rotating shaft 70 is also accommodated inside the mounting ring 67, so the rotating shaft 70 is not cut out. Forming can improve the strength of the opening operation part 59 . Moreover, since the position of the handle part 60 moves upward and the opening operation part 59 enlarges, the intensity|strength of the opening operation part 59 tends to fall. However, the handle portion 60 is formed asymmetrically in the width direction, and the direction of the tangent line S at the central portion of the outer edge 75 of the handle portion 60 forms an angle θ2 with the direction of the center line L of the rotation shaft 70. Sufficient strength can be secured by adding reinforcing members such as metal plates. Furthermore, the rotation when the user pulls the handle portion 60 is efficiently transmitted to the connection portion G, and the engagement of the lock mechanism 47 is quickly released, so that the door 11 can be easily opened and closed. Thereby, operability when the user opens the door body 11 can be improved, and usability can be improved.

In the present embodiment, as shown in FIG. 6 , the handle portion 60 is asymmetrically provided at a position higher than the width direction (W direction) of the lid opening operation portion 59 . For example, by setting the width W of the handle portion 60 to about 100 mm so that four fingers can fully enter, and setting the entire width of the opening operation portion 59 to about 200 mm, which is twice the width W, it is possible to close the handle to the housing 12. The position of the handle portion 60 is set asymmetrically above the position in the height direction. Furthermore, an angle θ1 (inclination with respect to the horizontal) of the handle portion 60 with respect to the horizontal centerline of the support frame 33 is set to 45°.

Since the position of the latch 71 cannot move relative to the center line of the door body 11 , the pressing piece 74 that transmits the rotation of the handle 60 to the latch 71 is located at the lower end on the opposite side of the handle 60 .

In addition, the width W of the handle portion 60 is set to be about 100 mm so that the four fingers can be fully inserted, but this is set for more convenient use, and it is not necessary to allow the four fingers to be fully inserted. The range is set smaller.

As described above, according to the structure of the present embodiment, although the opening operation part 59 is enlarged, the handle part 60 can be kept in a size necessary for hooking fingers, and its position can only be arranged at a lower position in the height direction of the housing 12. above. The handle portion 60 may also extend downward and be formed in the same size as the opening operation portion 59, but if the outer edge 75 of the handle portion 60 exposed radially outward from the outer circumference of the support frame 33 is similarly enlarged, it becomes larger. More obviously, the influence on the overall design of the washing and drying machine 50 becomes larger.

Thus, it is configured to suppress the size of the handle portion 60 to a size required for ease of use and to ensure design, and the handle portion 60 is arranged above the height direction of the housing 12 so that it becomes a position when the door is opened. At 11 o'clock, the angle θ1 between the centerline in the horizontal direction and the centerline in the horizontal direction that does not need to be bent over greatly is about 45°. Thereby, the operability when the user opens the door body 11 is improved, and usability can be improved.

As mentioned above, the laundry treatment device of this embodiment is a washing and drying machine 50, and includes a housing 12 and a door 11, wherein the housing 12 has an opening 24 for taking out and putting in clothes, and the door 11 is used to for opening and closing the opening portion 24 . Moreover, the door body 11 has the support frame 33, and the hinge structure 26, the lock mechanism 47, and the cover opening operation part 59 are provided in the support frame 33. As shown in FIG. The opening operation part 59 is configured to have a handle part 60 and a rotation shaft 70 for unlocking the lock mechanism 47 . In addition, the handle portion 60 is formed at a position close to the upper side in the height direction of the casing 12 in the width direction of the opening operation portion 59 .

According to such a structure, the operability when opening the door body 11 is improved, so even if the handle portion 60 is provided above the height direction of the casing 12 and the cover opening operation portion 59 is separated from the lock mechanism 47 and enlarged, The rotation axis 70 of the opening operation part 59 also tends to be closer to the outer edge 75 of the handle part 60 as it goes upward in the height direction of the casing 12 . Thereby, the rotating shaft 70 can be accommodated in the range which cannot be seen from the front, and as a result, the strength of the opening operation part 59 can be ensured without cutting out the center part of the rotating shaft 70. Therefore, the rotation of the opening operation part 59 when the handle part 60 is pulled is effectively converted to the release of the lock mechanism 47 via the link G, and the engagement is quickly released, thereby improving the operability when opening the door 11 .

In addition, the outer edge 75 of the handle portion 60 is formed as a concentric circular arc having a diameter larger than the diameter of the support frame 33 at a position outside the outer periphery of the support frame 33 . And, the direction of the tangent line S of the central portion of the outer edge 75 and the rotation axis 70 of the opening operation portion 59 form a predetermined angle, and the extension line of the tangent line S of the central portion of the outer edge 75 is related to the rotation of the opening operation portion 59. The extension lines of the center line L of the shaft 70 intersect at a position above the cap opening operation portion 59 .

According to this structure, the operability when opening the door body 11 is improved. Therefore, even if the handle portion 60 is provided above the height direction of the housing 12 and the cover opening operation portion 59 is separated from the lock mechanism 47 to increase in size, The rotating shaft 70 of the opening operation part 59 also tends to be closer to the outer edge 75 of the handle part 60 as it goes upward in the height direction of the housing 12, so the rotating shaft can be stored in a range that cannot be seen from the front. As a result, the strength of the opening operation portion 59 can be ensured without cutting out the central portion of the rotation shaft 70 . Therefore, the rotation of the opening operation part 59 when the handle part 60 is pulled is effectively converted to the release of the lock mechanism 47 via the link G, and the engagement is quickly released, thereby improving the operability when opening the door 11 .

In addition, the size of the gap d formed between the inner side of the outer edge 75 of the handle portion 60 and the outer periphery of the support frame 33 becomes larger as it goes higher in the height direction.

According to this structure, the turning radius of the opening operation part 59 from the turning shaft 70 is small, and the more it tends to interfere with the upper gap of the support frame 33 when turning, the more the margin increases. The lower gap is reduced, which can make the outer edge 75 of the handle portion 60 less conspicuous in design.

As described above, the present invention can exert the following special effects: the strength of the opening operation part can be ensured, and the position of the handle part as the handle part can be moved upward in the height direction of the casing and the operation when opening the door body can be improved. sex. Therefore, the present invention is useful as a laundry treatment device or the like that includes a door that closes or opens an opening for taking out and putting in clothes, and that performs at least one of washing and drying.
