When the user lifts-up the outer tub door 110, the drum door 310 is simultaneously opened. The drum door 310 has to be closed first when the outer tub door 110 is closed, so that the user visually recognizes the laundry when it is caught. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum type washing machine having a drum which rotates around a horizontal axis or a tilt axis. In general, a drum-type washing machine is often capable of continuously performing washing and drying, but the drum-type washing machine referred to here may not be capable of drying.

[0002]

2. Description of the Related Art A drum type washing machine has a structure in which a cylindrical basket-shaped drum is rotatably arranged inside an outer tub about a horizontal axis or an inclined axis, and laundry is stored in the drum. The laundry is hit and washed by rotating it in an outer tub that stores water. In such a general drum type washing machine, a door body for loading clothes is provided laterally on the front of a substantially rectangular parallelepiped outer box, and when the door body is opened through an opening provided in the outer tub, It is configured so that a clothing insertion port provided on one end surface of the drum can be seen.

One of the major complaints of general consumers about such a drum type washing machine is that it is difficult to put in and take out clothes. That is, therefore, in the drum-type washing machine having the above-mentioned configuration, even if the laundry loading port is located at a low position and the washing machine is placed on a dedicated stand, it is difficult to load the laundry completely. It will not be resolved. In order to deal with such dissatisfaction, there is a conventional drum-type washing machine commercially available in which a clothes inlet of the drum is slightly tilted upward by using an inclined shaft. Attempts have also been made to make the clothing inlet as large as possible. However, even with such a configuration, it cannot be said that the user who is accustomed to the operability of the whirlpool-type washing machine is sufficiently good in usability.

[0004]

One of the possible ways to eliminate the above-mentioned inconvenience in the drum type washing machine is to insert the laundry like the conventional spiral type washing machine. Is provided on the upper surface of the outer box, not on the front surface. However, when the laundry input port is provided on the upper surface of the outer case in the drum type washing machine, the outer tub arranged directly below the laundry input port and the drum housed inside the outer tub are opened respectively. Must be provided, which causes various problems different from those of the conventional spiral washing machine and drum type washing machine.

For example, in order to put laundry in and out of the drum, at least the outer tub door for opening and closing the opening provided on the peripheral surface of the outer tub and the opening and closing the opening provided on the peripheral surface of the drum are opened and closed. Although it is necessary to open the drum door, it is desirable that the door can be opened and closed as easily as possible for the convenience of the user. At the same time, when opening and closing the door,
The risk of clothing damage should be reduced as much as possible, such as by preventing the laundry from getting caught.

Further, since it is difficult to secure a wide opening because the opening is provided on the peripheral surface of the drum, it is desirable that the laundry be easily taken in and out. In addition, when loading or unloading the laundry, it is necessary to consider that it is difficult for the laundry to fall into the gap between the outer tub and the drum.

Furthermore, when an outer tub door is provided on the peripheral surface of the outer tub, water spattered from the laundry stored in the drum is sprinkled vigorously during the spin-drying operation, so that the outer tub opening has a peripheral edge. Water leaks easily from the gap between the outer tank and the outer tank door.

The present invention has been made in view of the above points, and an object of the present invention is to provide a drum type washing machine which is convenient for the user and which takes into consideration various points as described above. To provide.

[0009]

Means for Solving the Problems and Effects The first invention made to solve the above problems is that a drum having a substantially cylindrical peripheral surface is placed horizontally inside an outer tub arranged in an outer box. A drum-type washing machine rotatably arranged around a shaft or an inclined shaft, comprising an upper lid for opening and closing a laundry loading port formed on an upper surface of an outer box, and an outer tub below the laundry loading port. An outer tank door for opening and closing the outer tank opening formed on the peripheral surface and a drum door for opening and closing the drum opening formed on the peripheral surface of the drum are provided, and the upper lid, the outer tank door and the drum door are both opened. In a drum type washing machine for putting laundry in and out of the drum in such a state, a) outer tub door latch means for holding the outer tub door in a closed state, and b) urging the drum door in the opening direction. Biasing means, c) drum door latching means for holding the drum door closed, and d) user. And the operating means provided on the outer tub door, and e) acting on the outer tub door latching means and the drum door latching means in response to the operation of the operating means, and releasing the closed holding state of the drum door. At the same time, or a little later, latch release means for releasing the closed / held state of the outer tank door is provided.

In the drum type washing machine according to the first aspect of the present invention, when the drum is stopped, the drum stop position is fixed so that the drum stop position fixing means causes the drum opening position to substantially coincide with the outer tub opening position. Determined.

In the drum type washing machine according to the first aspect of the present invention, during the washing operation, the drum door and the outer tub door are latched so as not to be opened undesirably with the drum opening and the outer tub door closed, respectively. There is. When it is necessary to look inside the drum for the purpose of putting laundry in and out of the drum, etc., the user first opens the upper lid to look into the outer surface of the outer tub, and further operates the operating means to open the outer tub door. To operate. In response to this operation, the latch release means causes the drum door latch means to release the closed and held state of the drum door, and causes the outer tank door latch means to release the closed and held state of the outer tank at substantially the same time or slightly later. Since the drum door is urged in the opening direction by the urging means, when the closed and held state by the drum door latch means is released, the drum door is lifted in the opening direction, that is, in the direction of contacting the inner surface of the outer tank. The outer tank door is opened only after the closed holding state by the outer tank door latch means is released,
At the time of this opening, the drum door is in the state of being lifted as described above, and when the outer tank door is opened, the drum door follows the opening and opens almost integrally.

Therefore, according to the drum type washing machine of the first aspect of the present invention, the two-stage door opening operation of opening the outer tub door and then the drum door is not necessary, and the operation for opening and closing the drum door is performed. The user does not need to be conscious of doing so, and the time and effort required for loading and unloading the laundry can be reduced.

In the drum type washing machine according to the first invention, the outer tub door latch means and the drum door latch means are:
It is preferable that the outer tank door and the drum door are independently moved from the open state to the closed holding state. That is, when the door in the open state is closed, the two are not interlocked with each other, and the user first closes the drum door and then the outer tank door. If the drum door is configured to be closed in conjunction with the operation of closing the outer tub door, for example, the laundry is slightly protruding from the drum opening, and the end of the laundry bitten when the drum door is closed When hidden in the gap between the drum and the outer tank, the user is likely to overlook it. On the other hand, according to the above configuration, since the user needs to close the drum door before closing the outer tub door, when the drum door bites the laundry, it can be easily visually recognized. . Therefore, it is possible to prevent damage to the laundry due to biting of the laundry and damage to the washing machine itself while providing good usability.

In one embodiment, the latch releasing means projects toward the inside of the drum or retracts in the opposite direction in response to the operation of the operating means, and abuts against the drum door latch means by the projecting operation to latch the latch. It may be configured to include a first actuation body that is released and a second actuation body that releases the latch by driving the latch means of the outer tub door in conjunction with the operation of the operation means. With this configuration, the latch release timing of the outer tank door latching means and the drum door latching means can be determined by the difference in the timings at which the first operating body and the second operating body operate according to the operation of the operating means.

Further, normally, when the outer tank door is latched, the drum door is not opened (that is, the latch is not released), but the outer tank door is closed due to abnormal vibration or failure. Even if the drum door is opened, the drum door is driven to rotate in that state, causing the drum door to rotate while contacting the inner peripheral surface of the outer tank. Not only will it occur, but it may cause failure or damage. Therefore, in the drum type washing machine according to the first aspect of the present invention, a locking portion is provided on the back surface of the outer tub door, which comes into contact with the edge portion of the drum door when the drum is about to rotate with the drum door open. Is preferably provided.

According to this structure, when the outer door is closed and the latch of the drum door is disengaged to be in the half-opened state due to the biasing force, the edge of the drum door is locked on the rear surface of the outer tank door. The rotation of the drum is regulated by coming into contact with the portion. Therefore, if the drum is forcibly driven to rotate in this state, an abnormal load is applied to the drum motor, so that it is possible to detect that some abnormality has occurred. Therefore, the drum is not undesirably driven to rotate, and abnormal noise or damage can be prevented. In addition, as a preferable aspect, the locking portion may be a concave portion or a stepped portion that is recessed in the radial direction and into which an edge portion of the drum door enters when the drum door is opened. According to this, since the gap between the outer tank and the drum is not narrowed even if the locking portion is provided, it is possible to avoid contact with the outer tank even when the drum rotates with a large eccentricity.

A second invention made to solve the above-mentioned problems is such that a drum having a substantially cylindrical peripheral surface is rotatable around a horizontal axis or a tilt axis inside an outer tub arranged in an outer box. A drum type washing machine disposed on a top surface of the outer box for opening and closing a laundry loading opening, and an outer tub opening formed on a peripheral surface of the outer tub below the laundry loading opening. And a drum door that opens and closes a drum opening formed on the peripheral surface of the drum, and the laundry is placed inside the drum with the upper lid, the outer tub door, and the drum door open. In a drum type washing machine for putting in and out, on the upper surface of the outer tub door,
A handle portion having a recessed recessed portion on the front side for the user to insert a finger from the back side to the front side is provided, and a gate for molding the outer tank door with plastic is provided on the upper surface of the lower wall in the recessed portion. In addition to the provision, an inclined portion inclined upward from the back side to the front side is provided on the lower wall between the finger insertion opening of the recess and the gate.

That is, when the outer tank door is formed by general plastic molding, when the melted plastic resin is poured into the molding die, a projection is formed at the portion which will be the gate thereof. In the drum washing machine according to the second invention,
The gate is provided on the upper surface of the lower wall of the concave portion in order to prevent the user from seeing the above-mentioned protrusions that impair the quality of appearance. Furthermore, if the user touches the protrusion when inserting his / her finger into this recess, the fingertip may be damaged depending on the shape of the protrusion, and the impression that the product finish is defective even if the fingertip is not damaged. May be given to the user. If a sloped part is provided between the finger insertion port and the gate, as the finger is inserted deeply,
Since the fingertip is lifted along the inclination, it is possible to prevent the fingertip from touching the protrusion formed on the gate. This improves the visual appearance and
The safety of the user can be secured and the discomfort of the user can be eliminated.

A third aspect of the invention made to solve the above-mentioned problem is that a drum having a substantially cylindrical peripheral surface is freely rotatable around a horizontal axis or an inclined axis inside an outer tub arranged in an outer box. A drum type washing machine disposed on a top surface of the outer box for opening and closing a laundry loading opening, and an outer tub opening formed on a peripheral surface of the outer tub below the laundry loading opening. And a drum door that opens and closes a drum opening formed on the peripheral surface of the drum, and the laundry is placed inside the drum with the upper lid, the outer tub door, and the drum door open. In the drum type washing machine for loading and unloading, the outer tub side is provided with a detecting means for detecting the closing of the outer tub door, and the detecting means includes: a) when the outer tub door is in the closed position, A slide-movable transfer provided at the position where it is pressed by the member provided on the outer surface or outer tank door. A body, b) a torsion coil spring that biases the moving body toward the outer tank door, and c) an arm of the torsion coil spring rotates when the moving body receives the pressure and moves. And a switch having a movable piece at a position.

In the drum type washing machine according to the third aspect of the present invention, when the outer tub door is closed, the outer surface of the outer tub door or a member included in the outer tub door pushes the movable body against the biasing force of the coil spring. Then, the arm of the torsion coil spring rotates around the fixed shaft, and the arm pushes the movable piece of the switch, thereby closing (or opening) the switch. When the pressing by the actuating body is released by opening the outer tank door, the moving body returns to the original position by the biasing force of the torsion coil spring, and the pressing by the arm of the torsion coil spring is also released. Returns to its original position, which causes the switch to open (or close). That is, the moving body returns to the original position by the biasing force of the torsion coil spring outside the switch, not by the action of the spring built in the switch. The moving body can be restored, and opening / closing of the outer tank door can be accurately detected. Therefore, there is no erroneous detection of opening / closing of the outer tub door, and operation will start without the outer tub door being closed, or conversely, operation cannot be started even though the outer tub door is closed. Can be resolved.

A fourth aspect of the invention made to solve the above problems is such that a drum having a substantially cylindrical peripheral surface is rotatable around a horizontal axis or a tilt axis inside an outer tank provided in an outer box.

And a drum door that opens and closes a drum opening formed on the peripheral surface of the drum, and the laundry is placed inside the drum with the upper lid, the outer tub door, and the drum door open. In a drum type washing machine for loading and unloading, a packing made of an elastic body having a tongue piece extending inwardly in a tongue shape is provided around a peripheral wall of an outer tub which is erected around the outer tub opening. And the outer peripheral portion of the lower surface of the outer tank door is at the same extent as the lower end of the peripheral wall. It is characterized in that the pendent shape to the lower than that.

That is, during the dehydration operation, the drum is rotated at a high speed, and the water discharged from the laundry in the drum is vigorously sprayed toward the inner peripheral wall of the outer tub through the water passage holes of the drum. In the drum type washing machine according to the fourth aspect of the invention, when the water thus scattered comes toward the drum door and its surroundings, it first hits the hanging outer peripheral portion of the lower surface of the outer tub door and the peripheral wall of the outer tub, The tongue of the packing is reached after the water pressure has diminished. Therefore, since the water pressure applied to the contact portion between the tongue piece portion and the outer tank door can be reduced, high watertightness can be ensured and water leakage to the outside can be prevented.

The outer tub door 110 is wound around a shaft 111 by a torsion coil spring (not shown) in the opening direction (see FIG. 6).
In the clockwise direction). Inside the outer tub door 110, an outer tub door latch means for keeping the outer tub door 110 in a closed state by engaging with an edge portion of the outer tub 10 on the front side thereof, and a manual operation by a user are provided. Latch release means for releasing the latch by the outer tank door latch means and the latch by the drum door latch means.

The main constituent elements of the outer tub door latch means are locking cams 123 protruding forward from the front surface of the outer tub door 110,
Clutch cam 11 for restricting rotation of the locking cam 123
8 is a locking piece 130 fixed on the outer tank 10 side. The main component of the latch release means is the outer tank door 1.
Operation lever 112 and rod 11 provided on the upper surface of 10
6, the guide shaft 117, the traction shaft 122, and the like.

Explaining in order, on the upper surface of the outer tank door 110, an operating lever 112 as the above-mentioned operating means is provided.
3 is rotatable about 3 and is a torsion coil spring 114.
Are provided in a state of being urged clockwise in FIGS. 9 and 10. A finger insertion portion 115 that is recessed downward is formed on the upper surface of the outer tub door 110 on the rear side of the operation lever 112, and the user inserts the finger insertion portion 115 on the rear side (see FIG. 6).
Then, insert your finger from the right side), hang your finger under the operating lever 112, and pull the operating lever 112 to raise it. When the operating lever 112 is pulled in this way, the spring 1
The operation lever 112 stands up against the urging force of 14 (see FIG. 10), but when the user releases his finger, the operation lever 112 immediately returns to the original position by the urging force of the spring 114.

The housing of the outer tank door 110 is the upper member 11
0a and the lower member 110b, which are both plastic molded products. In order to mold such a member with a mold, a gate into which a melted plastic resin is poured is required, and in a molded product, a protrusion is formed at a position corresponding to the gate. If such protrusions are in a position where they can be seen by the user, the appearance will deteriorate, so the upper member 1
In 10a, the gate is placed inside the finger insertion portion 115, and as a result, as shown in FIG.
A protrusion 110c is formed on the lower wall portion of No. 5. This part is hidden by the operating lever 112, so that the appearance is good, but when the operating lever 112 is operated as described above, the projection 110
If the user's finger touches c, the finger may be injured. Therefore, as shown in FIG. 11, an inclined surface 115a that gently rises from the rear to the front is provided on the lower wall of the finger insertion portion 115, and at a position slightly distant from the uppermost portion of the inclined surface 115a to the front side. The protrusion 110c is formed.

With the above structure, the user operates the operation lever 11
When the fingertip is inserted into the finger insertion portion 115 to cause 2, the back side of the finger hits the lower wall and the fingertip advances obliquely upward along the inclined surface 115a. Therefore, place your finger on the finger insertion unit 1.
Even if it is inserted all the way to the back of the finger 15, the fingertip is positioned above the protrusion 110c and escapes contact with the protrusion 110c. Therefore, high safety can be secured.

Returning to FIG. 9 and FIG. 10, the description will be continued. In front of the operating lever 112, the outer tub 1 is provided by the guide shaft 117.
Rod 1 supported to move in and out toward 0
16 is provided as the first actuation body. The end of the operating lever 112 is connected to the upper end of the rod 116, and when the operating lever 112 is in the normal position, the rod 116 is in the most raised position and does not protrude from the inner peripheral surface of the outer tub 10 (see FIG. 9). And the operating lever 11
2, the rod 116 is pushed down as the operation lever 112 rotates, and the lower end of the rod 116 advances inside the outer tub 10. When the drum 116 is in the predetermined stop position, when the rod 116 moves to the maximum, it abuts on the receiving plate 318 of the front door body 312 of the drum door 310 and pushes it down. This depressing operation is performed by the engaging claw 317 of the drum door 310 and the engaging hole 3
This is an operation for releasing the fitting with 19.

A clutch cam 118 is rotatably provided in front of the guide shaft 117 around a shaft 120 formed on a clutch mounting plate 119, and the clutch cam 118 is a torsion coil spring wound around the shaft 120. It is urged by 121 in the clockwise direction in FIGS. 9 and 10. Further, the clutch cam 118 is provided on the traction shaft 12 which is the second actuating body.
2 is connected to the operation lever 112 via the control lever 112, and when the operation lever 112 is raised toward the front as described above, the traction shaft 122 is pulled rearward so that the spring 12
The clutch cam 118 rotates counterclockwise against the biasing force of 1.

In front of the clutch cam 118,
A locking cam 123 is rotatably provided around a shaft 124 formed on the clutch mounting plate 119, and the locking cam 123 is biased counterclockwise by a torsion coil spring 125. The locking cam 123 is provided with a bite portion 123a that is formed by projecting from the front surface of the outer tub door 110 to the front and is composed of two upper and lower protruding pieces similar to the beak shape of a bird, and is fitted to the clutch cam 118 on the rear side. The step portion 123b is provided.

The outer tub 10 facing the front edge of the outer tub door 110
At the opening edge portion of the projecting piece portion 1 which is one member constituting the outer tank door latch means as a part of the housing 131 described later.
30 is provided, and the protruding piece 130 is used to lock the cam 1.
When the clenching part 123a of 23 bites, the outer tank door 1
10 is latched in the closed state.

Next, the operation of opening and closing the outer tank door 110 and the drum door 310 with the upper lid 2 opened will be described. Now, as shown in FIG. 9, both the outer tank door 110 and the drum door 310 are assumed to be latched in the closed state. At this time, the bite portion 12 of the locking cam 123
3a bites the protruding piece 130 on the outer tank 10 side, and the locking cam 1
The rotation of 23 is locked by the clutch cam 118, and the traction shaft 122 for rotating the clutch cam 118 is in a state of not applying a force to the clutch cam 118. That is, the outer tub door 110 is in the closed state, and it is possible to prevent the outer tub door 110 from opening naturally even when an external force such as a large vibration is applied.

When the user inserts his / her finger into the finger insertion portion 115 to open the outer tank door 110 and raises the operation lever 112 toward the front as shown in FIG. 10, the operation lever 112 is opened.
Rotates about the shaft 113, and the rod 11 moves with the rotation.
6 descends. As described above, since the receiving plate 318 of the front door body 312 of the drum door 310 exists just at the advanced position of the rod 116, the receiving plate 318 is pressed downward in the state shown in FIG. As shown in A), the front door body 312 pivots around the front shaft 311 so as to sink. Then, the engaging claws 317 are engaged with the engaging holes 319.
Therefore, the force pulling the rear door body 314 downward is released against the biasing force of the torsion coil spring 316, and the rear door body 314 is rotated in the opening direction by the biasing force. Following this, the front door body 312 also tries to open in the opening direction.

On the other hand, since the traction shaft 122 is pulled rearward as the operation lever 112 rotates, the clutch cam 118 counterclockwise rotates about the shaft 120 against the urging force of the spring 121. Rotate in the direction. Then, the clutch cam 118 becomes the step portion 12 of the locking cam 123.
Since it is disengaged from 3b, the locking cam 123 becomes rotatable and tries to rotate in the counterclockwise direction by the biasing force of the spring 125. Due to this force, the bite portion 123a on the upper side of the locking cam 123 pushes down the projecting piece 130, so that the biting is released and the front edge of the outer tub door 110 is slightly lifted as the locking cam 123 rotates. That is, the pulling operation of the pulling shaft 122 is an operation of releasing the closed holding state of the outer tank door 110. Therefore, the outer tank door 1
Which of 10 and the latch of the drum door 310 is released first is determined by the timing of the advancing operation of the rod 116 and the towing operation of the tow shaft 122 corresponding to the turning operation of the operation lever 112, and here is the reason described later. Thus, the latch of the drum door 310 is released slightly ahead of the latch of the outer tank door 110.

That is, in the process in which the user pulls the operation lever 112 toward the front as described above, as described above, the drum door 3
The latch 10 is released, and the rear door body 3 is released immediately after the release.
14 and the front door body 312 are lifted by the urging force, but at the above timing, the outer tank door 110 is at that time.
Since the latch has not been released or is in the process of being released, the outer tank door 110 is not yet opened, and both door bodies 312 and 314 of the drum door 310 contact the lower surface of the outer tank door 110. . Therefore, when the user pulls up the outer tub door 110 and opens it to the rear side after the outer tub door 110 is unlatched, the rear door body 314 is moved to the outer tub door 314 by the urging force of the spring 316. While being attached to the lower surface of 110, the front door body 312 pivots almost integrally to the rear side, and the front door body 312 pivots to the front side after a delay via the link body 322. In this way, the rear door body 314 of the drum door 310 is opened integrally with the opening operation of the outer tank door 110, and finally the both door bodies 31 are opened.
2, 314 can be a double door.

Considering that there is a little time before the user operates the operation lever 112 and pulls up the outer tank door 110, the latch of the drum door 310 and the outer tank door 110 are practically used. Even if the latch is released almost simultaneously, the rear door body 314 of the drum door 310 can be opened integrally with the opening operation of the outer tank door 110.

Further, on the lower surface of the lower member 110b of the outer tank door 110, when the rear door body 314 is opened, the rear door body 31 is formed.
4 is provided with a concave portion 110d for receiving the light. for that reason,
As shown in FIG. 10, when the rear door body 314 is opened while the outer tank door 110 is closed, the edge portion of the rear door body 314 enters the recess 110d. For example, when the latch of the drum door 310 is undesirably released due to vibration or the like instead of the operation by the user, the rear door body 31 is unloaded as described above.
Since the edge portion of No. 4 enters the recess 110d, when the drum 13 is driven to rotate in this state, the edge portion of the rear door body 314 contacts the step of the recess 110d. Therefore, an abnormally large load is applied to the drum motor 20, and the abnormality can be detected.

The user, for example, puts the laundry in the drum 13 and then the drum door 31 which is slightly tilted rearward.
The rear door body 314 of 0 is rotated to the front side to perform the closing operation. At this time, due to the action of the link body 322, the front door body 312 rotates before reaching the rear door body 314 and reaches the position for closing the drum opening 300, and then the rear door body 31.
4 overlap. Then, when the user slightly presses the protective cover 324 of the rear door body 314, the engaging claws 317 are fitted into the engaging holes 319, and the drum door 310 is in a latched state. At this time, the user can immediately recognize if the laundry is protruding and is bitten by the door.

After closing the drum door 310 as described above,
The user rotates the outer tub door 110 to the front side. Then,
The bite portion 123a on the upper side of the locking cam 123 has the protruding piece portion 130.
When the user presses the outer tub door 110 against the urging force of the spring 125, the locking cam 12 is pressed against the urging force of the spring 125.
3 rotates in the clockwise direction, the clutch cam 118 is fitted into the step portion 123b of the locking cam 123, and the locking cam 123
Is fixed. As a result, the outer tank door 110 is also latched in the closed state.

In the drum type washing machine of this embodiment, the outer tub door 110 and the drum door 310 are opened and closed as described above. The outer tub door 110 is opened and closed as described above.
It is detected by the outer tank door open / close detection mechanism provided so as to face the front edge portion of 0. This detection mechanism is provided in the housing 131 fixed to the outer tank 10 side. FIG. 12 is a side elevational cross-sectional view (A) and a top view (B) of a main part of this outer tank door open / close detection mechanism.

A pin 132 is provided slidably in the front-rear direction in the housing 131 having the projecting piece 130 formed on the upper portion thereof, and the tip end of the pin 132 is rearward from the housing 131, that is, the outer tank door 110. Protruding towards the front of the. The pin 132 is pushed toward the outer tub door 110 by the movable plate 134 biased by the torsion coil spring 133, and a switch 135 is arranged in front of the movable plate 134.

When the outer tank door 110 is open, the pin 1
Since 32 does not receive a force from the rear (right side in FIG. 12), it is advanced to the outer tank door 110 side by the biasing force of the spring 133, and the movable plate 134 moves the movable element 13 of the switch 135.
5a is not pressed. When the outer tub door 110 is closed and latched as described above, the lower bite 123a of the locking cam 123 pushes the pin 132 against the biasing force of the spring 133. As a result, the movable plate 134 pushes the mover 135a of the switch 135, and the switch 135 changes from closed to open (or vice versa). As described above, since the external torsion coil spring 133 is used, the switch 135 can be surely opened / closed.

Next, the outer tank 10 for receiving the outer tank door 110.
The configuration on the side will be described with reference to the drawings. 13 is a top view showing the front edge portion of the outer tub opening 100 of the drum type washing machine of this embodiment, FIG. 14 is a vertical cross-sectional view taken along the line DD 'in FIG. 13, and FIG. 15 is B in FIG. -B'longitudinal sectional view taken along the arrow, FIG. 16 shows outer tank door 11
16 is a vertical cross-sectional view of the main part in a state where 0 is closed, FIG.
It is an enlarged view of the F section inside.

The outer tank 10 is formed to form the outer tank opening 100.
A frame-shaped outer tank cover 200 is attached to the peripheral portion of the opening provided in the body portion 10a of the body, and the outer tank cover 200 is made of an elastic material to seal a gap between the outer tank cover 110 and the outer tank door 110 with water. The packing 210 is attached. Outer tank cover 200
For example, as shown in FIG. 15, the boss 10b that is erected on the outer tub body 10a is fixed with a screw 201. At that time, the hanging end 200b of the outer tub cover 200 has a cross section of the packing 210. The edge portion 210c which is covered from the inside with the U-shaped portion 210b and extends from the U-shaped portion 210b is sandwiched between the outer tank body portion 10a and the outer tank cover 200.
Therefore, as the screw 201 is tightened more strongly, the edge portion 210c of the packing 210 is crushed and the outer tank body portion 10a is crushed.
The adhesion with

Also, high standing walls 200a, 210a are formed on either the outer tank cover 200 or the packing 210 so as to surround the outer tank opening 100. The standing wall 20
0a and 210a cover the screw 201 for fixing the outer tank cover 200 and extend outward and higher than it. Further, the central portion 211 of the front edge of the packing 210 is
Has a shape lower than both sides thereof as shown in FIG. For this reason, when the outer tub door 110 is opened, the outer tub opening 100 has a mortar shape except for the front edge, and it is difficult for the outer tub opening 100 to fall outside when the laundry is put in or taken out. Also, since the center of the front edge is low, it does not get in the way when loading and unloading laundry. Further, when water is spilled on the front edge, the water gathers in the center along the slope and then flows down into the outer tub 10. Therefore, the outer tank 10
It is possible to prevent water from spilling to the outside of the screw as much as possible, and also to prevent the screw 201 from getting wet.

On the inside of the packing 210, an extending piece 210d extending inwardly in a tongue shape is formed over substantially the entire circumference, and as shown in FIG. 16, the outer tank door 110 is closed. Then, the extending piece 210d is bent and closely adheres to the outer tank door 110 to ensure watertightness. However, if a strong water force hits the close contact portion, it causes water leakage. Therefore, as shown in FIG. 17, the outer peripheral edge portion 110e of the outer tank door 110 hangs down.
It is lowered to the same level as the lower end of the packing 210 on the outside or a position lower than that. Further, a hanging piece 110f is also formed on the upper part of the hanging piece 110f so that the gap between the hanging piece 110f (or the outer tank cover 200) on the outer side thereof is narrowed. With the above configuration, even if a strong water force is applied to the gap, the water force is rapidly weakened and the force is lost by the time the extension piece 210d is reached. Therefore, the high water-tightness between the extension piece 210d and the outer tank door 110 is not impaired.

As described above, in the drum type washing machine of the present embodiment, it is easy to put the laundry in and out of the drum 13, or the high water-sealing property when the outer tub door 110 is closed. It has a structure that can be secured.

The above embodiment is an example of the present invention, and it is clear that appropriate changes and modifications can be made within the scope of the present invention.
