JP 2017-99994 A

However, with conventional door lock structures that simply engage the door hook, it is difficult for the user to know whether the door hook is securely engaged and the door is completely closed, which can lead to the user feeling uneasy that the door is not completely closed. Furthermore, with conventional door lock structures that simply engage the door hook, there are cases in which the door hook is actually not completely engaged.

Therefore, this embodiment provides a clothing processing device that makes it easier for the user to recognize that the door is completely closed and prevents the door hook from being incompletely engaged.

The clothing processing device according to this embodiment comprises a clothing processing device main body, a door, a locking portion, a door hook, a contact prevention portion , and a door hook insertion portion . The door opens and closes a front opening of the clothing processing device main body. The locking portion is rotatably provided on the clothing processing device main body. The door hook is rotatably provided on the door and has a locking portion with which the locking portion locks when the door is in a state where the door is closing the front opening. The contact prevention portion is provided on the door hook and prevents the locking portion from contacting the locking portion when the door is in the process of closing the front opening. The door hook insertion portion is provided on the clothing processing device main body, and the door hook is inserted into it when the front opening is closed by the door. The door hook insertion portion has an inclined wall portion at the entrance portion, and the contact prevention portion protrudes toward the inclined wall portion in a direction perpendicular to the longitudinal direction of the door hook , with the surface at the tip side being an inclined surface, and in the process of the door blocking the front opening, the contact prevention portion abuts against the inclined wall portion of the door hook insertion portion to rotate the door hook in a direction away from the engaging portion and prevent the engaging portion from contacting the engaged portion, and when the contact prevention portion advances rearward beyond the rear end portion of the inclined wall portion of the door hook insertion portion, the door hook rotates in a direction approaching the engaging portion so that the engaging portion engages with the engaged portion, and the door is locked in a closed state blocking the front opening .

Hereinafter, an embodiment of a clothes processing device will be described with reference to the drawings. The washing machine 1 illustrated in FIG. 1 and FIG. 2 is an example of a clothes processing device that performs a predetermined process on clothes, in this case at least a washing process, a rinsing process, and a dehydration process. The washing machine 1 is a so-called drum-type washing machine in which the rotation center axis of the rotating tub extends horizontally or in a direction inclined to the horizontal direction. The washing machine 1 is provided with a bottomed cylindrical water tub that can store water, a water supply mechanism that supplies water to the water tub, and a drainage mechanism that discharges water from the water tub to the outside of the machine inside the washing machine main body 2 that constitutes its outer shell. The drum 3 is rotatably provided inside the water tub. The front opening of the water tub and the front opening of the drum 3 face the front opening 4 provided on the front of the washing machine main body 2. In this case, the front opening 4 of the washing machine main body 2 is opened in a circular shape, and a user can put laundry such as clothes into the drum 3 through this front opening 4.

The washing machine 1 is provided with a door 5 that opens and closes the front opening 4 of the washing machine main body 2. The door 5 has a circular shape corresponding to the front opening 4 of the washing machine main body 2, and is provided rotatably by a hinge portion 6. The door 5 is provided with a door handle 7 that is operated by a user. In this case, the door handle 7 is provided on the right side of the upper part of the outer periphery of the door 5 when viewed from the front side of the washing machine 1 in a closed state in which the door 5 closes the front opening 4. In addition, a recessed portion 7a is provided around the front opening 4 of the washing machine main body 2 in a portion facing the door handle 7 in a closed state in which the door 5 closes the front opening 4. When the user wants to open the door 5, the user can easily operate the door handle 7 by inserting his or her fingers into the recessed portion 7a and pulling it from the back side to the front side.

2, the washing machine body 2 is provided with a claw portion 110. In this embodiment, the washing machine body 2 is provided with a door hook insertion hole portion 8 on the right side of the front opening 4 when viewed from the front side of the washing machine 1. In this embodiment, the door hook insertion hole portion 8 is opened in a rectangular shape, and the claw portion 110 is provided in the back of the door hook insertion hole portion 8. On the other hand, the door 5 is provided with a door hook 120. In this embodiment, the door hook 120 is provided so as to protrude from the back surface of the door 5 at the free end of the door 5, that is, the end opposite to the end pivotally supported by the hinge portion 6. The end of the back surface of the door 5 where the door hook 120 is provided faces the door hook insertion hole portion 8 of the washing machine body 2 in a closed state in which the door 5 closes the front opening 4. The door hook insertion hole portion 8 is a hole portion into which the door hook 120 is inserted when the front opening 4 is closed by the door 5.

As shown in FIG. 3, the washing machine 1 has a door lock structure 100 that mainly includes a claw portion 110 provided on the washing machine main body 2 side and a door hook 120 provided on the door 5 side, and that locks the door 5 in a closed state in which the door 5 closes the front opening 4. Next, a detailed description of an example of the configuration of this door lock structure 100 will be given.

The claw portion 110 is an example of a locking portion. As illustrated in FIG. 4, the claw portion 110 is configured such that the claw body portion 111 forming the base of the claw portion 110 is integrally provided with a claw-shaped protrusion portion 112 and a pivot shaft portion 113. The claw-shaped protrusion portion 112 extends from the claw body portion 112 in a gently curved manner. The pivot shaft portion 113 extends in a straight line. The claw-shaped protrusion portion 112 is gently curved so as to follow the circumferential direction of the pivot shaft portion 113.

As shown in FIG. 3, the claw portion 110 is disposed in the back of the door hook insertion hole 8 with the inner surface of the gently curved claw-shaped protrusion 112 facing the rear of the washing machine 1. The claw portion 110 is provided in the back of the door hook insertion hole 8 so as to be rotatable in the directions of the arrows R1 and R2 about the pivot shaft 113. A coil spring 9 is provided in the back of the door hook insertion hole 8. The coil spring 9 is an example of a biasing member, and biases the rotatable claw portion 110 in the direction of the arrow R1. The biased claw portion 110 rotates in the direction of the arrow R2 against the biasing force of the coil spring 9 in response to the application of an external force in the direction of the arrow R2 to the claw portion 110. In other words, the claw portion 110 is configured so that it is not generally allowed to rotate due to the biasing force of the coil spring 9, but is configured so that its rotation is allowed in response to the application of an external force of a predetermined magnitude or greater, that is, a force that exceeds the biasing force of the coil spring 9.

In this embodiment, an inclined wall 8a is provided at the entrance of the door hook insertion hole 8. In this case, the inclined wall 8a is provided at the inner part of the entrance of the door hook insertion hole 8, which is on the front opening 4 side. The inclined wall 8a is inclined with respect to the insertion direction D1 and removal direction D2 of the door hook 120 into the door hook insertion hole 8, and is also inclined with respect to a direction perpendicular to the insertion direction D1 and removal direction D2 of the door hook 120 into the door hook insertion hole 8. Here, the insertion direction D1 and removal direction D2 of the door hook 120 into the door hook insertion hole 8 are along the front-rear direction of the washing machine 1. In addition, the direction perpendicular to the insertion direction D1 and removal direction D2 of the door hook 120 into the door hook insertion hole 8 is along the left-right direction of the washing machine 1.

A rear wall 8b is provided on the rear side of the inclined wall 8a. The rear wall 8b is a wall that is perpendicular to the insertion direction D1 and removal direction D2 of the door hook 120 into the door hook insertion hole 8, in this case, the front-to-rear direction of the washing machine 1. The rear wall 8b is also a wall that is parallel to the direction perpendicular to the insertion direction D1 and removal direction D2 of the door hook 120 into the door hook insertion hole 8, in this case, the left-to-right direction of the washing machine 1.

In contrast to the claw portion 110 configured in this manner, the door hook 120 is configured to integrally include a door hook main body portion 121 and a pivot shaft portion 122, as shown in FIG. 5. The door hook main body portion 121 has an elongated rectangular shape overall. The door hook main body portion 121 has a protrusion portion 123 and a locking hole portion 124 at its tip.

The protrusion 123 is an example of a contact prevention portion, and protrudes in a mountain shape from the tip of the door hook main body 121 in a direction perpendicular to the longitudinal direction of the door hook main body 121. In this embodiment, multiple protrusions 123, in this case two, are provided, and are provided at the tip of the door hook main body 121 in pairs with a predetermined gap between them along the axial direction of the pivot shaft 122. These multiple protrusions 123 also have the same shape.

The surface at the tip end of the protrusion 123 is an inclined surface 123a that is inclined in both the longitudinal direction of the door hook main body 121 and in a direction perpendicular to the longitudinal direction of the door hook main body 121. This inclined surface 123a is an example of an insertion smoothing portion that facilitates the insertion of the door hook 120 into the door hook insertion hole. The surface at the base end of the protrusion 123 is an inclined surface 123b that is inclined in both the longitudinal direction of the door hook main body 121 and in a direction perpendicular to the longitudinal direction of the door hook main body 121. This inclined surface 123b is an example of a removal smoothing portion that facilitates the removal of the door hook 120 from the door hook insertion hole.

In this embodiment, the inclined surface 123a is configured to be more gently inclined with respect to the longitudinal direction of the door hook main body 121 than the inclined surface 123b. In other words, the inclined surface 123b is configured to be inclined at an angle that is nearly perpendicular to the longitudinal direction of the door hook main body 121. In addition, in this embodiment, the inclined surface 123a is longer than the inclined surface 123b.

The locking hole 124 is an example of a locked portion, and penetrates the tip of the door hook main body 121 in a direction perpendicular to the longitudinal direction of the door hook main body 121. In this embodiment, the locking hole 124 is provided between the two protrusions 123, and opens in a substantially rectangular shape.

The pivot shaft 122 extends in a straight line. The base end of the door hook main body 121 is connected to one end of the pivot shaft 122 in the longitudinal direction. The axial direction of the pivot shaft 122 is perpendicular to the longitudinal direction of the door hook main body 121. A step 125 is provided in the middle part of the door hook main body 121, in this case, the part between the locking hole 124 and the pivot shaft 122. This step 125 is continuous with the locking hole 124.

As shown in FIG. 3, the door hook 120 is provided at the right end of the door 5 so as to be rotatable around a pivot shaft 122 in the directions of the arrows R3 and R4. A coil spring (not shown) is provided inside the door 5. This coil spring biases the rotatable door hook 120 in the direction of the arrow R3. The door hook 120 thus biased is adapted to rotate in the direction of the arrow R4 against the biasing force of the coil spring (not shown) in response to the operation of the door handle 7 by the user. Even when the door handle 7 is not operated, the door hook 120 is adapted to rotate in the direction of the arrow R4 in response to the application of an external force in the direction of the arrow R4, i.e., a force exceeding the biasing force of the coil spring (not shown).

Next, in the washing machine 1 equipped with the door lock structure 100 configured as described above, the following cases will be described: when the front opening 4 is closed by the door 5; when the door 5 is opened by operating the door handle 7 to open the front opening 4; and when the door 5 is opened from inside the washing machine main body 2 to open the front opening 4.

(When the front opening 4 is closed by the door 5)
As illustrated in FIG. 6, in the process of rotating the door 5 in the closing direction to close the front opening 4, the tip of the door hook 120 on the door 5 side is gradually inserted into the door hook insertion hole 8 on the washing machine main body 2 side as the door 5 rotates in the closing direction. At this time, as the door hook 120 enters the door hook insertion hole 8, the inclined surface 123a of the protruding portion 123 of the door hook 120 slides while abutting against the inclined wall portion 8a of the door hook insertion hole 8. Therefore, the protruding portion 123 of the door hook 120 is pushed by the inclined wall portion 8a of the door hook insertion hole 8, and accordingly, as illustrated in FIG. 7, the door hook 120 gradually rotates in the direction of the arrow R4. At this time, as the door hook 120 enters the door hook insertion hole 8, the door hook 120 rotates largely in the direction of the arrow R4. In other words, the door hook 120 is adapted to be rotated significantly toward the arrow R4 side by an amount corresponding to the amount of protrusion of the protruding portion 123 that protrudes from the side portion of the door hook main body 121.

When the protrusion 123 of the door hook 120 advances rearward beyond the rear end of the inclined wall 8a of the door hook insertion hole 8 as the door 5 rotates in the closing direction, the pressing action of the inclined wall 8a of the door hook insertion hole 8 on the protrusion 123 of the door hook 120 is released, and the door hook 120 rotates in the direction of arrow R3 due to the biasing force of the coil spring on the door 5 side (not shown). As a result, as illustrated in FIG. 8, the claw-shaped protrusion 112 of the claw portion 110 engages with the locking hole 124 of the door hook 120, and the door 5 is locked in a closed state that blocks the front opening 4.

At this time, the rear wall 8b of the inclined wall 8a of the door hook insertion hole 8 is engaged with the inclined surface 123b of the protrusion 123 of the door hook 120. In other words, the door 5 is locked not only by the claw-shaped protrusion 112 of the claw portion 110 engaging with the locking hole 124 of the door hook 120, but also by the rear wall 8b of the inclined wall 8a of the door hook insertion hole 8 engaging with the inclined surface 123b of the protrusion 123 of the door hook 120. Here, the claw-shaped protrusion 112 of the claw portion 110 is an example of a first locking portion provided on the washing machine main body 2 side, and the locking hole 124 of the door hook 120 is an example of a first locked portion provided on the door hook 120 side. Additionally, the rear wall 8b of the inclined wall 8a of the door hook insertion hole 8 is an example of a second locking portion provided on the washing machine body 2 side, and the inclined surface 123b of the protrusion 123 of the door hook 120 is an example of a second locked portion provided on the door hook 120 side.

As explained above, when the door 5 is in the process of closing the front opening 4, the protrusion 123 of the door hook 120 abuts against the inclined wall 8a of the door hook insertion hole 8, causing the door hook 120 to rotate significantly in the direction of arrow R4. As a result, the protrusion 123 of the door hook 120 prevents the claw-shaped protrusion 112 of the claw portion 110 from contacting the locking hole 124 of the door hook 120 when the door 5 is in the process of closing the front opening 4.

(When the door 5 is opened by operating the door handle 7 to open the front opening 4)
Although detailed illustration is omitted, when a user opens the door 5, the user operates the door handle 7. Then, in conjunction with the operation of the door handle 7, the door hook 120 rotates in the direction of the arrow R4, whereby the claw-shaped protrusion 112 of the claw portion 110 is released from the locked state in the locking hole 124 of the door hook 120. This releases the locked state of the door 5, and the user can open the door 5 and expose the front opening 4 by rotating the door 5 in the opening direction.

(When the door 5 is opened from inside the washing machine body 2 to open the front opening 4)
The washing machine 1 according to this embodiment is configured so that the door 5 can be opened from inside the washing machine body 2 to open the front opening 4. In more detail, when a force of a predetermined magnitude is applied from the rear surface of the door 5 to the door 5 closing the front opening 4, as illustrated in Fig. 9, an external force F1 that tends to rotate the claw portion 110 in the direction of arrow R2 is applied to the claw-shaped protrusion 112 of the claw portion 110 from the locking hole 124 of the door hook 120 that tends to move in the removal direction D2.

Here, the biasing force of the coil spring 9 is set to a strength that basically maintains the claw-shaped protrusion 112 of the claw portion 110 in an engaged state in the engagement hole portion 124 of the door hook 120, and is set to a strength that allows rotation in the direction of the arrow R2 when a force of a predetermined magnitude or more, in this case a force of 7000 cN or more, is applied. Therefore, when a force of 7000 cN or more is applied to the back surface of the door 5 that blocks the front opening 4, an external force F1 acts on the claw-shaped protrusion 112 of the claw portion 110 from the engagement hole portion 124 of the door hook 120, and the claw portion 110 rotates in the direction of the arrow R2. As a result, the engagement state in which the claw-shaped protrusion 112 of the claw portion 110 is engaged with the engagement hole portion 124 of the door hook 120 is released. As a result, the locked state of the door 5 is released, and the door 5 can be opened by pushing the door 5 from inside the washing machine main body 2 to open the front opening 4.

9, in the washing machine 1 according to this embodiment, in the closed state in which the door 5 closes the front opening 4, the axis 122a of the pivot shaft 122 of the door hook 120 is configured to be located outside the outer periphery of the door 5, in this case, on the right side of the washing machine 1, from the locking position P1 where the claw-shaped protrusion 112 of the claw portion 110 locks with the locking hole 124 of the door hook 120. Therefore, when a force of a predetermined magnitude or more is applied to the back surface of the door 5 closing the front opening 4, the reaction force applied from the claw-shaped protrusion 112 of the claw portion 110 to the locking hole 124 of the door hook 120, that is, the reaction force F2 against the above-mentioned external force F1, becomes more likely to act in a direction that rotates the door hook 120 in the direction of the arrow R4, and the rotation of the door hook 120 in the direction of the arrow R4 can also be promoted. Therefore, by rotating the claw portion 110 in the direction of the arrow R2 and rotating the door hook 120 in the direction of the arrow R4, the claw-shaped protrusion 112 of the claw portion 110 becomes more easily disengaged from the locking state in which it is locked in the locking hole portion 124 of the door hook 120, making it easier to open the door 5.

In addition, in the process of opening the door 5, the door hook 120 is removed from the door hook insertion hole 8. At this time, the inclined surface 123b of the protruding portion 123 of the door hook 120, which engages with the rear wall portion 8b of the inclined wall portion 8a of the door hook insertion hole 8, is inclined with respect to the rear wall portion 8b of the inclined wall portion 8a of the door hook insertion hole 8. This makes it possible to smoothly remove the door hook 120 from the door hook insertion hole 8. This makes it easier to release the state in which the rear wall portion 8b of the inclined wall portion 8a of the door hook insertion hole 8 engages with the inclined surface 123b of the protruding portion 123 of the door hook 120, making it easier to open the door 5.

According to the washing machine 1 of this embodiment, a protrusion 123 is provided on the side of the long rectangular door hook 120, and in the process of the door 5 closing the front opening 4, the protrusion 123 is configured to rotate the door hook 120 significantly, preventing the claw-shaped protrusion 112 of the claw portion 110 from contacting the locking hole portion 124 of the door hook 120. With this configuration, when the door hook 120, which has rotated significantly in the direction of arrow R4 during the process of being inserted into the door hook insertion hole portion 8, returns in the direction of arrow R3, that is, when the claw-shaped protrusion 112 of the claw portion 110 engages with the locking hole portion 124 of the door hook 120, a loud sound can be generated by the momentum of the return of the door hook 120. As a result, based on the generation of this sound, it is possible to easily recognize that the claw-shaped protrusion 112 of the claw portion 110 engages with the locking hole portion 124 of the door hook 120 and the door 5 is completely closed. In addition, when the door hook 120 returns in the direction of the arrow R3, the force of the coil spring on the door 5 side (not shown) can forcefully rotate the door hook 120 toward the claw portion 110, preventing the door hook 120 from being incompletely engaged with the claw portion 110.

In addition, according to the washing machine 1, in a closed state in which the door 5 closes the front opening 4, the axis 122a of the pivot shaft 122 of the door hook 120 is provided outside the outer periphery of the door 5 from the locking position P1 where the claw-shaped protrusion 112 of the claw portion 110 locks with the locking hole 124 of the door hook 120. With this configuration, when a force of a predetermined magnitude or more is applied to the back surface of the door 5 closing the front opening 4, the rotation of the door hook 120 in the direction of the arrow R4 can be promoted, making it easier to open the door 5. Note that the "outer periphery" in this embodiment is intended to mean the outer periphery within the door 5, and does not mean the concept of the outside including the outside of the door 5. In addition, in this embodiment, the door 5 is circular. Therefore, the "outer periphery" can also be defined as the "outer radial direction".

In addition, according to the washing machine 1, the biasing force of the coil spring 9 is set to a biasing force capable of maintaining the claw-shaped protrusion 112 of the claw portion 110 in a locked state in which it is locked with the locking hole 124 of the door hook 120, and is set to a biasing force that allows the claw-shaped protrusion 112 of the claw portion 110 to be rotated by the locking hole 124 of the door hook 120 in response to a force of a predetermined magnitude or more being applied to the door 5 blocking the front opening 4 from the back side of the door 5. In this way, a biasing force that basically locks the door 5 in a closed state while also allowing the door 5 to be opened from inside the washing machine main body 2 can be easily realized by selecting the spring force of the coil spring 9, that is, by selecting the type of coil spring 9 to be assembled to the washing machine 1.

In addition, according to the washing machine 1, the door hook 120 extends linearly and protrudes from the back surface of the door 5. Therefore, the door hook 120 can function as a blocking prevention part that prevents the door 5 from blocking the front opening 4 when the door 5 moves in a direction that blocks the front opening 4 under its own weight. In other words, if the door 5 only moves in a direction that blocks the front opening 4 under its own weight, the tip of the door hook 120 comes into contact with the inclined wall portion 8a of the door hook insertion hole portion 8, and the door 5 can be prevented from blocking the front opening 4 unless an external force is applied to the door 5 in the blocking direction. Therefore, it is possible to prevent the door 5 from unintentionally blocking the front opening 4.

In addition, according to the washing machine 1, the inclined surface 123a of the protrusion 123 provided at the tip of the door hook 120 functions as an insertion facilitation portion that facilitates the insertion of the door hook 120 into the door hook insertion hole. This facilitates the insertion of the door hook 120 when the user operates the door 5 to close the front opening 4, making it even easier to close the door 5.

In addition, according to the washing machine 1, the inclined surface 123b of the protrusion 123 provided at the tip of the door hook 120 functions as a removal smoothing portion that facilitates removal of the door hook 120 from the door hook insertion hole. This makes it possible to smoothly remove the door hook 120 when opening the door 5 that is blocking the front opening 4, making it even easier to open the door 5.

Note that this embodiment is not limited to the above-mentioned embodiment, and various modifications and extensions can be made without departing from the gist of the embodiment. For example, the configuration of the claw portion 110 and the door hook 120 is not limited to the above-mentioned configuration example, and can be appropriately modified and implemented without departing from the gist of the embodiment. For example, the locking portion may not be configured as a claw, and the locked portion may not be configured as a hole. In addition, the washing machine 1 may be configured to have a dedicated blocking prevention portion, such as a pin or a protrusion, that prevents the door 5 from blocking the front opening 4 when the door 5 moves in a direction that blocks the front opening 4 due to its own weight. In addition, the washing machine 1 may be a so-called washing and drying machine that can also perform a drying process on clothes. In addition, this embodiment is not limited to the washing machine 1, and can be applied to various devices that are configured to perform a predetermined process on clothes, such as a dryer that performs a drying process on clothes and a deodorizing device that deodorizes clothes.

Note that this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. This embodiment and its variations are included within the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.
