  In the conventional configuration, for example, as shown in FIG. 9A, the handle 101 is pivotally supported by a holding shaft 103 provided on the inner lid 102 side by a rotating shaft 104 and rotates around the rotating shaft 104. It is provided as possible. When the handle 101 is rotated, the restricting portion 105 provided on the handle 101 is accordingly rotated and received by the receiving portion 106 provided on the inner lid 102 side. Thereby, it is a structure (rotation prevention structure of a handle | steering-wheel) in which rotation of the handle | steering-wheel 101 is controlled.

  However, in such a structure, if an excessive force (rotational power) is further applied to the handle 101 after the rotation of the handle 101 is restricted, the strength of the restricting portion 105 with respect to the force cannot be maintained. As shown in (b), the restricting portion 105 may be deformed and the handle 101 cannot be prevented from rotating. In particular, when the deformation amount of the restricting portion 105 is large, the rotating shaft 104 may come off from the holding portion 103. In such a case, the handle 101 itself cannot be prevented from rotating, and the handle 101 itself is There also arises a problem that the inner lid 102 is detached.

  Here, as a configuration that solves such a problem, a configuration that reinforces the regulating portion 105 or a configuration that changes the material, or a configuration that restricts deformation of the regulating portion 105 by providing a rib or the like on the receiving portion 106 is considered. It is done. However, in such a configuration, there is a possibility that the structure becomes complicated and the cost is high, or the manufacturability is deteriorated when the handle is attached to the inner lid.

  According to the present invention, when the handle is rotated by a predetermined amount, the restricting portion that rotates together with the handle is received by the receiving portion, and thereby the rotation of the handle is prevented. At this time, when an excessive force is further applied to the handle, the restricting portion is guided toward the restricting portion by a guide portion provided in a part of the receiving portion so as to face the restricting portion. Thereby, the deformation | transformation of the rotation part direction of the control part accompanying rotation of a handle | steering-wheel can be limited to a restriction | limiting part direction, and a stable detent of a handle | steering-wheel can be implement | achieved with such an inexpensive and simple structure. it can.

The drive mechanism 22 includes, for example, an outer rotor type motor (not shown) and a clutch (not shown) that selectively transmits the rotation of the motor to the rotary tank 15 and the agitator 20. By this drive mechanism 22, only the stirring body 20 is rotationally driven in the washing process and the rinsing process, and the rotary tank 15 is rotationally driven together with the stirring body 20 in the dehydration process and the drying process.

  On the other hand, the top cover 3 is formed with a loading port 3a for loading and unloading laundry at the center thereof, and an outer lid 23 is rotatably attached to open and close the loading port 3a. In this case, the outer lid 23 is configured to be folded in two, and has a plurality of cutout portions 23a on the peripheral side portion thereof. As a result, a gap is formed between the outer cover 23 in the closed state and the surface of the top cover 3, and air permeability inside and outside the washing machine 1 is ensured. And in the part which protrudes upwards in the rear part of the top cover 3, the warm air production | generation unit 24, the water supply apparatus which is not shown in figure, etc. are arrange | positioned.

  The hot air generation unit 24 includes a blower 25 and a heater 26. The blower 25 includes a casing 28 having an air inlet 27 on the rear surface, a fan 29a accommodated in the casing 28, and a fan motor 29b that rotationally drives the fan 29a. Further, the heater 26 is formed of, for example, a PTC heater, and is provided at a front end portion in the casing 28 and at a portion downstream of the blower 25. And the front-end part of the casing 28 is connected to the hot air connection port 36 (refer FIG. 2) of the rear part of the tank cover 9 via the bellows-shaped air supply duct 30. As shown in FIG.

  A filter device 31 is disposed at the rear end of the top cover 3. Air outside the washing machine 1 (outside air) is taken in from the air inlet 27 through the filter device 31 as indicated by broken line arrows in FIG. 1, passes through the hot air generating unit 24 as hot air, and the water tank 4 and the rotating tank 15. Supplied in. The supplied hot air contributes to the drying action of the laundry (clothing, etc.) in the rotary tub 15, passes through the air passage 11 from the lower part of the water tub 4, and is discharged from the air guide 13 to the outside of the water tub 4. The air discharged to the outside of the water tub 4 is discharged out of the washing machine 1 through the notch 23a of the outer lid 23 or the opening at the lower end of the outer box 2.

  On the upper surface of the front portion of the top cover 3 is provided an operation panel 32 provided with a start switch (not shown) and operation keys for setting various operation courses. A control device 33 is arranged on the back side of the operation panel 32. It is installed. The control device 33 is mainly composed of a microcomputer, and controls the overall operation of the washing machine 1.

  Next, a specific configuration of the tank cover 9 will be described with reference to FIG. FIG. 2 is a plan view schematically showing the tank cover 9 provided with the inner lid 10. As shown in FIG. 2, the tank cover 9 is formed with an opening 34 having a large opening in a substantially semicircular shape (a non-circular shape in which the rear side is linearly formed) from the center portion to the front portion. . A reinforcing member 35 made of an aluminum member containing, for example, aluminum or an alloy thereof is attached to the peripheral portion of the opening 34. The reinforcing member 35 is subjected to a rust-proofing treatment or a treatment for aesthetic purposes (for example, a surface treatment such as alumite treatment or cationic electrodeposition coating). A cylindrical warm air connection port 36 and a water supply connection port 37 projecting upward are formed side by side at the rear portion of the tank cover 9 (the portion behind the opening 34). A water supply device (not shown) is connected to the water supply connection port 37.

  The opening 34 is formed as an opening for taking in and out the laundry, and a support tool 38 is provided at the linear rear end thereof. In the inner lid 10, the hinge portion 10 a on the base end side is pivotally supported by the support 38, and it is between the position where the opening 34 is closed (closed position) and the position where the opening 34 is opened (open position). It is provided so as to be rotatable.

  Next, the configuration of the inner lid 10 will be described with reference to FIG. FIG. 3 is a longitudinal side view schematically showing the front end portion (free end portion on the side opposite to the shaft support) of the inner lid 10 and its peripheral portion. In this case, the inner lid 10 has a double plate configuration, the front surface side (the outer side of the water tub 4) is configured by a heat-resistant resin surface plate 39, and the rear surface side (the inner side of the water tub 4) is The back plate 40 is made of an aluminum member. The back plate 40 is also subjected to the same processing as the reinforcing member 35. The inner lid 10 is assembled by screwing the front plate 39 and the back plate 40 at a plurality of locations. Further, the inner lid 10 has a configuration having a gap between the front plate 39 and the back plate 40.

  A lid packing 41 is disposed on the outer edge portion of the inner lid 10 so as to follow the opening shape of the opening 34. The lid packing 41 is attached in a state where the base end portion is sandwiched between the back surface of the outer edge portion of the front plate 39 and the surface of the outer edge portion of the back plate 40. Therefore, in a state where the inner lid 10 closes the opening portion 34, the tip end portion of the lid packing 41 is elastically pressed against the periphery of the opening portion 34, whereby the inside of the water tank 4 becomes airtight and watertight.

  A handle 42 made of an elastically deformable resin (for example, polypropylene, ABS resin, etc.) is provided at the distal end of the inner lid 10 in order to open and close the inner lid 10. Here, the configuration of the handle 42 and the structure for preventing the rotation of the handle 42 will be described with reference to FIGS. 4 and 5. FIG. 4 is an enlarged perspective view showing the front end portion of the inner lid 10 from the back side, and FIG. 5 is an enlarged perspective view showing an attachment portion between the inner lid 10 and the handle 42. The structure shown in FIG. 5 is configured symmetrically at the left and right ends of the handle 42.

  The handle 42 has a front end portion formed in a substantially arc shape in cross section and a rear end portion formed in a substantially straight line shape. The rear end portion of the handle 42 functions as a handle portion 42a (see FIG. 2) to be put on when the user rotates the handle 42. In addition, a pair of restricting portions 43 projecting in a direction substantially orthogonal to the handle portion 42a (downward in FIG. 4) are integrally formed at the left and right end portions of the handle 42. As shown in FIG. 5, these restricting portions 43 have a shape in which a portion on the inner lid 10 side is inclined, and as a whole, has a tapered shape that gradually decreases toward the tip portion. A pair of rotating shafts 44 (see FIG. 4) that protrude along the left-right direction of the inner lid 10 are integrally provided on the outer surfaces of the restricting portions 43. Further, a rib 45 is integrally formed on the inner side surface of the restricting portion 43, whereby the restricting portion 43 is reinforced.

  On the other hand, a pair of holding portions 46 that protrude outward in a circular arc shape are integrally provided at the distal end portion of the inner lid 10, and these holding portions 46 penetrate in the left-right direction of the inner lid 10. A shaft insertion hole 46a (see FIG. 4) is formed. The rotation shaft 44 of the handle 42 is inserted into the shaft insertion hole 46a from the inside, whereby the handle 42 is pivotally supported by the rotation shaft 44 at the distal end portion of the inner lid 10. (See arrows A1 and A2 in FIG. 3). The rotation range of the handle 42 according to the present embodiment is determined by the rotation prevention structure of the handle 42 from the normal position (the position where the handle 42 is tilted toward the inner lid 10 shown in FIG. 3) to the release position (the position raised with respect to the inner lid 10). However, it is restricted to a range up to the position where the lock of the inner lid 10 is released by the configuration described later. Further, the restricting portion 43 formed integrally with the handle 42 is also rotated together with the handle 42 (see arrows A1 and A2 in FIG. 5).

  Further, a receiving portion is located on the front end portion of the inner lid 10 on the turning locus of the restricting portion 43 accompanying the turning of the handle 42 (a portion of the inner lid 10 that intersects the arrow A1 direction shown in FIG. 5). 47 is provided. A guide portion 48 is provided in a portion of the receiving portion 47 that faces the restricting portion 43. The guide portion 48 is gradually inclined obliquely rearward from the central portion side (right side in FIG. 5) to the holding portion 46 side (left side in FIG. 5) of the inner lid 10 tip, and the inside is high and the outside is It has a low slope shape. A flat portion 47 a formed in a planar shape along the left-right direction and the thickness direction of the inner lid 10 is provided on a portion of the receiving portion 47 outside the guide portion 48 (on the holding portion 46 side). It has been. Further, a rib 49 extending in the thickness direction of the inner lid 10 is provided in a portion of the receiving portion 47 on the inner side of the guide portion 48 (on the central portion side of the distal end portion of the inner lid 10).

  A hook member 50 made of an elastically deformable resin is provided at a substantially central portion inside the handle 42. As shown in FIG. 3, the hook member 50 is provided with a claw portion 50a (corresponding to a hook), a contact portion 50b, and an elastic piece portion 50c. The claw portion 50a protrudes obliquely upward at the lower end portion of the hook member 50 on the side opposite to the inner lid 10 (left side in FIG. 3). The contact portion 50 b protrudes at the upper portion of the hook member 50 so as to face the inner surface of the front end portion of the handle 42. The elastic piece portion 50c extends to the inner lid 10 side (right side in FIG. 3), and is locked to the distal end portion of the inner lid 10 so as to be elastically deformable. On the other hand, the water tank 4 (tank cover 9) is provided with an engaging member 51 located at the front part of the opening 34. The engaging member 51 is provided with a claw portion 51a (corresponding to an engaging portion) that protrudes obliquely downward toward the inner lid 10 at the upper end portion.

  With such a configuration, when the inner lid 10 is rotated to the closed position (a state where the opening 34 is closed), the claw portion 50a of the hook member 50 is moved by the elastic force of the elastic piece portion 50c. It is biased outward (left side in FIG. 3) and engages with the claw portion 51 a of the engaging member 51. Thereby, the inner lid 10 is locked at the closed position. Further, when the handle 42 is turned in this direction from the state indicated by the arrow A1 in FIG. 3, the contact portion 50b is pressed by the inner surface of the front end portion of the handle 42, and the elastic piece portion 50c is compressed and deformed. Along with this, the claw portion 50a of the hook member 50 is released from the claw portion 51a of the engaging member 51, the lock of the inner lid 10 is released, and the inner lid 10 can be opened. Thus, the claw part 50a provided in the handle 42 is detachably provided on the claw part 51a provided in the water tank 4 as the handle 42 rotates from the steady position to the release position. And the handle | steering-wheel 42 provided with such a hook member 50 functions as a holding means which hold | maintains the inner cover 10 in a closed position.

  Next, the operation of the anti-rotation structure of the handle 42 configured as described above will be described with reference to FIGS. 6 to 8 schematically show attachment portions of the inner lid 10 and the handle 42, respectively. FIG. 6 shows a state before the handle 42 is rotated (state in a steady position), and FIG. FIG. 8 shows a state in which the restricting portion 43 comes into contact with a part of the receiving portion 47 as the handle 42 is turned (a state in which the turning of the handle 42 is restricted). FIG. It shows the moved state. Moreover, (a) of each figure is a cross-sectional view which shows the attachment part of the handle | steering-wheel 42 from the back surface side of the inner cover 10, (b) is a longitudinal cross-sectional view of the said attachment part.

  When the user rotates the handle 42 in the arrow A1 direction by pulling the handle portion 42a of the handle 42 upward from the state (steady position) shown in FIG. As shown in FIG. 7, it rotates in the A1 direction and abuts against and is received by a part of the receiving portion 47 (in this case, the guide portion 48 that faces the regulating portion 43). Thereby, the rotation of the handle 42 in the arrow A1 direction is restricted, and the handle 42 is prevented from rotating. At this time, the engagement between the claw portion 50a of the hook member 50 and the claw portion 51a of the engagement member 51 is released, and the lock of the inner lid 10 is released (release position).

  From this state, when excessive force (turning force in the direction of arrow A1) is applied to the handle 42 and the handle 42 is further rotated in the direction of arrow A1, the restricting portion 43 that rotates together with the handle 42 is As shown in FIG. 8, the guide portion 48 is deformed to the holding portion 46 side while being guided to the holding portion 46 side.

  Then, the restricting portion 43 comes into contact with the side surface portion of the holding portion 46, thereby restricting deformation of the restricting portion 43. That is, a part of the holding portion 46 (in this case, the side surface portion) functions as the restricting portion 52 that restricts deformation of the restricting portion 43. The distal end portion of the restricting portion 43 whose deformation is restricted by the restricting portion 52 comes into contact with and is received by the flat portion 47 a of the receiving portion 47. Thereby, the further rotation of the handle 42 is restricted.

  The restricting portion 43 is integrally formed with a handle 42 made of an elastically deformable resin. Therefore, the restricting portion 43 is also elastically deformable. For this reason, after the rotation of the handle 42 is restricted, if an excessive force is further applied to the handle 42 in the turning direction, the strength of the restricting portion 43 with respect to the force cannot be maintained and the restricting portion 43 is deformed. It can be considered. However, in this embodiment, when an excessive force is applied after the rotation of the handle 42 is restricted, the restricting portion 43 is guided to the restricting portion 52 side by the guide portion 48, and the guide portion 48 and the restricting portion 52 In the meantime, the flat part 47a of the receiving part 47 is received. Therefore, even if an excessive force is applied to the handle 42 after the rotation of the handle 42 is restricted, the deformation of the restricting portion 43 can be suppressed.

As described above, according to the present embodiment, when the handle 42 is rotated by a predetermined amount (in this case, from the steady position shown in FIG. 6 to the release position shown in FIG. 7), the handle 42 rotates together with the handle 42. The restricting portion 43 to be received is received by the receiving portion 47, whereby the handle 42 is prevented from rotating. At this time, when an excessive force is further applied to the handle 42, the restricting portion 43 is guided toward the restricting portion 52 by the guide portion 48 provided in a part of the receiving portion 47 so as to face the restricting portion 43. The Thereby, the deformation | transformation of the rotation axis 44 direction (left-right direction in FIG. 6 thru | or FIG. 8) of the control part 43 accompanying the excessive rotation of the handle | steering-wheel 42 can be limited to the restriction | limiting part 52 direction. Further, the anti-rotation structure of the handle 42 according to the present embodiment is a simple structure using an inexpensive resin material. With such an inexpensive and simple structure, a stable anti-rotation of the handle 42 can be realized. it can.
Further, by using an inexpensive resin material, it is possible to improve the structure for preventing the rotation of the handle 42 and thus the productivity of the washing machine 1.

  Since the guide portion 48 has a slope shape, the restricting portion 43 can be smoothly deformed in the direction of the restricting portion 52 along the guide portion 48, and the operational feeling of the handle 42 can be improved.

  Since a part of the holding part 46 (in this case, the side part) is configured as the restriction part 52, it is not necessary to secure a new space for providing such a restriction part, and space saving can be achieved. A simpler structure can be obtained.

  As the restricting portion 43 is deformed to the restricting portion 52 side, the gap between the handle 42 and the holding portion 46 (gap indicated by reference sign G in FIG. 6) becomes narrower. Accordingly, it is difficult to cause the rotation shaft 44 of the handle 42 to come out of the shaft insertion hole 46a of the holding portion 46, and it is possible to prevent the occurrence of a problem that the handle 42 itself is detached from the inner lid 10.

  Further, the restricting portion 43 that rotates together with the handle 42 is guided in the direction of the restricting portion 52 by the guide portion 48 as the handle 42 rotates. Thereby, the user can guide the restricting portion 43 in the direction of the restricting portion 52 by using the force of rotating the handle 42, and a special configuration for guiding the restricting portion 43 (for example, the restricting portion 43). There is no need to provide a spring member or the like that biases the

  Since the rib 49 is provided on the inner side of the guide portion 48 in the receiving portion 47, when the restricting portion 43 comes into contact with the receiving portion 47 as the handle 42 rotates, the restricting portion 43 is attached to the handle 42. It can prevent that it deform | transforms inside.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The rotation range of the handle 42 can be set to an appropriate range by changing, for example, the shape and size of the restricting portion 43.
The receiving portion 47, the guide portion 48, the limiting portion 52, etc. are not limited to those formed in a planar shape, and may be, for example, part or all having protrusions. .

  The application target of the handle rotation prevention structure of the present invention is not limited to the washing machine 1 including the water tank 4 as a container and the inner lid 10 as a lid. In short, as long as it has a lid provided in the container and a handle provided in the lid in order to put the contents in and out of the container, the anti-rotation structure of the handle of the present invention is applied. be able to.
