The interior of the door 20 is hidden.

When changing the opening direction of the door 20, the door 20 is first removed from the washing machine main body 10.例文帳に追加When the door 20 is removed from the washing machine main body 10, the door-side first upper hinge cover member 35A and the door-side first lower hinge cover member 35B are removed from the door-side upper hinge opening 34A and the door-side lower hinge opening 34B. Remove. As a result, the hinge pin 31 is completely exposed in the door-side hinge opening 34, and when the door 20 is lifted upward, the engagement between the hinge arm 30 and the hinge pin 31 is released, so that the door 20 is removed from the washing machine main body 10. be able to. The door 20 cannot be lifted unless the cover member 35A for the door-side first upper hinge and the cover member 35B for the door-side first lower hinge are removed, and the hinge arm 30 and the hinge pin 31 must be disengaged. I can't do it either.

After the door 20 is removed, the hinge arm 30 and the body-side hinge cover member 33 are removed in order to change the position of the hinge arm 30 in the washing machine body 10 . Since these are attached to the washing machine main body 10 with screws or the like, they can be removed by removing the screws.

In the drum-type washing machine 1 according to Embodiment 1, the hinge arm 30 and the body-side hinge cover member 33 are used as left and right components. Therefore, the hinge arm 30 and the body-side hinge cover member 33 are replaced with left and right parts, respectively, and the left and right hinge arms 30 and the body-side hinge cover member 33 are changed using the replaced parts. The parts to be replaced may be brought by the serviceman who performs the operation of changing the opening direction of the door, or may be separately obtained and owned by the user.

As for the door lock, the main body side first door lock cover member 43 and the main body side second door lock cover member 44 are removed, and the door lock device 40 is removed. These can also be easily removed from the washing machine main body 10 by removing the screws. The removed door lock device 40 is attached to the main body 10 of the washing machine again after the attachment position is reversed from side to side (at this time, the vertical direction of the door lock device 40 is reversed). It should be noted that replacement of the door lock device 40 will be described in more detail in Embodiments 2 and 3, which will be described later.

In drum-type washing machine 1 according to Embodiment 1, body-side first door lock cover member 43 and body-side second door lock cover member 44 are used as left and right common parts. Although the body-side first door lock cover member 43 and the body-side second door lock cover member 44 are not point-symmetrical by themselves, they have the same outer diameter shape. Can be shared. Therefore, the main body side first door lock cover member 43 and the main body side second door lock cover member 44 do not need to be replaced with separate parts. I do. As with the main body side hinge cover member 33, the main body side first door lock cover member 43 and the main body side second door lock cover member 44 are not common to the right and left sides, but are separate parts. It is also possible to bring parts and make corresponding shapes.

On the other hand, from the door 20 removed from the washing machine main body 10, the door-side second hinge cover member 36, the door-side first door lock cover member 46, and the door-side second door lock cover member 47 are removed (door The side first upper hinge cover member 35A and the door side first lower hinge cover member 35B have already been removed when the door 20 is removed). After the cover member 35 for the first door-side hinge and the cover member 36 for the second door-side hinge are removed, the left and right hinge pins 31 are replaced. In this embodiment, the hinge pins and cover members on the door side are separate left and right parts like the main body side, and replacement is performed by a serviceman who brings separate parts, but it is also possible to make it easier if left and right common parts are used. is.

As for the door lock on the door 20 side, the position of the door hook 41 of the door 20 can be changed by replacing the door-side first door-lock cover member 46 and the door-side second door-lock cover member 47 . Further, since the door-side second upper hinge cover member 36A is provided with a handle 50, the left-right replacement of the door-side first upper hinge cover member 35A and the door-side second upper hinge cover member 36A enables The position of the handle 50 can be changed.

Door 20 to which cover members other than door-side first upper hinge cover member 35A and door-side first lower hinge cover member 35B are attached is attached to washing machine main body 10 again. At this time, the tip of the hinge arm 30 is inserted into the door-side upper hinge opening 34A and the door-side lower hinge opening 34B, and the hinge pin 31 is inserted into the tip of the hinge arm 30 from above so that the door 20 is attached. After the door 20 is attached to the washing machine main body 10, the door-side first upper hinge cover member 35A and the door-side first lower hinge cover member 35B are finally attached to complete the operation of changing the door opening direction. .

In the drum-type washing machine 1 exemplified in the above description, various left and right parts that need to be replaced when changing the door opening direction can be made common left and right parts by devising their shapes. It is possible. In other words, all of the cover members that cover the symmetrically provided openings may be common left and right parts, but some cover members are separate left and right parts for reasons of design, for example. may be

As described above, in the drum-type washing machine 1 according to Embodiment 1, the body-side hinge opening 32 and the door-side hinge opening 34 (hinge mounting opening) are symmetrically arranged at the mounting positions of the hinges. , and the hinge mounting opening on the side where the hinge is not provided is hidden by a body side hinge cover member 33 and a door side second hinge cover member 36 (blindfold cover member).

Also, the hinge attachment openings are provided separately in the upper and lower portions. Since the hinge mounting openings are separately provided in the upper and lower portions in this way, the area of these openings themselves becomes small, and there is no need to provide a large opening on the front surface of the washing machine main body 10. The strength and design of the front surface of the main body 10 can be improved. In such a drum-type washing machine 1, large-sized parts such as the panel part forming the front surface of the washing machine body 10 and the door 20 itself can be shared regardless of the door opening direction. As a result, when service personnel change the door opening direction at the user's home, there is no need to bring large replacement parts, making it easier to provide a service to change the door opening direction. possible).

In addition, since the hinge mounting openings are separately provided on the upper and lower sides, the distance between the upper and lower hinges can be set long without sacrificing the strength and design of the front surface of the washing machine main body 10. Even if the positional deviation occurs due to the attachment and detachment of the door, it is possible to reduce the positional deviation between the door and the washing machine body, so that it is possible to suppress the sealing failure of the door. In addition, it is possible to reduce the size of the blind cover member for the hinge attachment opening.

As a result, when a service person changes the door opening direction at the user's house, there is no need to bring a large replacement part, and the service of changing the door opening direction can be easily provided.

In addition, it is assumed that a sufficiently large working space cannot be secured when changing the door opening direction at the user's home. Even in such a case, if the parts that need to be removed are miniaturized, it will be easier to work in a narrow space.

In addition, by providing the hinge mounting opening and the door lock mounting opening symmetrically, it becomes easier to use the blindfold cover as a left-right common part. can be reduced, which is advantageous in terms of cost.

Further, in the drum-type washing machine 1 according to Embodiment 1, the upper hinge arm 30A is positioned above the laundry inlet 101 in the vertical direction. Also, the lower hinge arm 30B is located below the laundry inlet 101 in the vertical direction. Therefore, the upper hinge arm 30A and the lower hinge arm 30B can be arranged with the laundry inlet 101 interposed therebetween in the vertical direction, and the position of the hinge arm is slightly displaced by attaching and detaching the upper hinge arm 30A and the lower hinge arm 30B. Even in this case, it is possible to minimize positional deviation of the projecting closing portion 201 of the door 20 with respect to the laundry inlet 101 when the door 20 is closed. Furthermore, since the distance between the upper hinge arm 30A and the lower hinge arm 30B can be increased, the amount of positional deviation of the hinge arms due to attachment and detachment of the upper hinge arm 30A and the lower hinge arm 30B is reduced when the door 20 is closed. It is possible to minimize the amount of positional deviation of the protruding closing portion 201 of the door 20 with respect to the laundry inlet 101 .

In addition, since the upper hinge arm 30A and the lower hinge arm 30B can be arranged so as not to overlap the laundry inlet 101 in the vertical direction, the upper hinge arm 30A or the lower hinge arm 30B provided on the left and right sides of the washing machine main body 10 are fixed. The hinge mounting portions for the washing machine main body 10 can be provided on a reinforcing member bridged over the left and right sides of the washing machine body 10 . Therefore, the strength of the hinge mounting portion can be improved without interfering with the laundry inlet 101 . At least one of a configuration in which the upper hinge arm 30A is positioned above the laundry inlet 101 in the vertical direction, and a configuration in which the lower hinge arm 30B is positioned below the laundry inlet 101 in the vertical direction. may have been implemented.

[Embodiment 2]
In Embodiment 2, a configuration example for making replacement of the door lock device 40 easier will be described with reference to FIG. FIG. 5 is a schematic diagram showing a connection configuration between the door lock device 40 and the electrical circuit 60 inside the washing machine main body 10. As shown in FIG.

An electric circuit 60 connected to the door lock device 40 via wiring 61 is provided inside the washing machine main body 10 , and the lock mechanism of the door lock device 40 is controlled by the electric circuit 60 . An intermediate connector 62 is provided in the middle of the wiring 61 .

In the drum-type washing machine 1 according to Embodiment 2, the electrical circuit 60 is arranged near the center of the upper portion of the washing machine body 10, and the wiring 61 is located near the center of the electrical circuit 60 (that is, in the width direction of the washing machine body 10). It extends downward from the center). Washing machine main body 10 according to Embodiment 2 has electrical circuit front opening 63 in addition to main body side hinge opening 32 and main body side door lock opening 42 . Normally, a cover member (not shown) is attached to the electrical circuit front opening 63, but when the cover member is removed from the electrical circuit front opening 63, the connecting portion between the electrical circuit 60 and the wiring 61 is exposed. 5, from the main body side hinge opening 32 and the main body side door lock opening 42, the main body side hinge cover member 33, the door side first door lock cover member 46, and the door side second door lock cover member are shown. 47 is removed, and the cover member is also removed from the opening 63 in front of the electrical circuit. Further, it is assumed that the hinge arm 30 has also been removed from the body-side hinge opening 32 .

In the operation of changing the mounting position of the door lock device 40, the connector connection of the intermediate connector 62 is first released from the state shown in FIG. This unlocking operation can be performed inside the body-side door lock opening 42 . By releasing the intermediate connector 62, the door lock device 40 can be temporarily removed from the washing machine main body 10, and can be replaced by exchanging the left and right attachment locations.

The wiring 61 from which the intermediate connector 62 has been removed is pulled out by a worker (for example, a serviceman) by inserting his/her hand (or finger) into the opening 63 in front of the electrical circuit, and then switching the left and right directions to insert the wiring 61 into the washing machine main body 10 . The wiring 61 can be drawn around. After that, the middle connector 62 is reconnected to the door lock device 40 whose attachment point is switched between the left and right sides, and the replacement work of the door lock device 40 is completed.

In addition, the arrangement route of the wiring 61 passes through the vicinity of the body-side hinge opening 32 so that the operator can easily perform the above-described work. Moreover, it is desirable that the electrical circuit front opening 63 and the body-side hinge opening 32 have an area that allows the operator to easily perform the above-described work. If the main body side hinge opening 32 has a certain area and it is possible to replace the left and right sides of the wiring 61 only through the work from the main body side hinge opening 32, the opening 63 in front of the electrical circuit and the cover member may be used. may not be provided. In this case, a worker (for example, a serviceman) may put his or her fingers or a jig into the body-side hinge opening 32 to pull the wire 61 by hand.

In this configuration, when replacing the door lock device 4, the vertical direction of the door lock device 40 is reversed. That is, in the configuration of FIG. 5, the connection point between the door lock device 40 and the wiring 61 is on the upper side of the door lock device 40, but when the vertical direction of the door lock device 40 is reversed, it is on the lower side. Therefore, when the connection point between the door lock device 40 and the wiring 61 is located below the door lock device 40, the necessary length of the wiring 61 is longer than when it is located above. For this reason, it is assumed that the actual wiring 61 has a sufficient length to accommodate upside-down of the door lock device 40 (in FIG. 5, the wiring 61 is shown short for the sake of simplification of the drawing). ing).

As described above, in drum-type washing machine 1 according to Embodiment 2, intermediate connector 62 is provided on wiring 61 that connects electrical circuit 60 and door lock device 40 . Therefore, by releasing the connector connection of the intermediate connector 62 , the work of changing the mounting position of the door lock device 40 can be easily performed in a state in which the connection with the wiring 61 is eliminated.

In addition, the electrical circuit 60 is arranged near the upper portion of the washing machine body 10, and there are a plurality of openings (the electrical circuit front opening 63, the body A side hinge opening 32 and a body side door lock opening 42) are provided. Therefore, the work of routing the wiring 61 inside the washing machine main body 10 can be performed through the plurality of openings. Each opening can have a small area, and the cover members attached to these openings can also be miniaturized. That is, there is no need to remove a large panel member (front plate or ring decoration) covering the front surface of the washing machine body 10 for the routing work of the wiring 61, and no need to prepare a large panel member or the like as a replacement part.
