The acute-angle hook 29b is adjacent to the obtuse-angle hook 29a, and is provided on the side opposite to the operation handle 30 with respect to the obtuse-angle hook 29a, and is rotatably supported around the second support shaft 41 as a shaft. A torsion spring 42b is provided coaxially at the second support shaft 41 and faces the direction that opens the acute-angle hook 29b, that is, from the hook capacity provided at the hook control means 38. The direction separated by means 37b is pushed.

8 and 10 are the same as those shown in FIG. 5 (a). The oblique-angle hook 29 a is located in a closed position and is fitted with the hook receiving means 37 a to show the closed state “closed state” of the cover 7. At this time, the acute-angle hook 29b is located at the open position.

〈Opening and releasing operation〉

When the cover body 7 is opened from the "closed state" while the clothing 6 is in and out, the operation handle 30 is operated as shown in Figs. 6 to 7.

FIGS. 9 and 11 are the same as those in FIG. 7, and show a state in which the hook operation portion 40 provided at one end of the operation handle 30 is operated when the operation handle 30 is operated.

As shown in FIG. 9 and FIG. 11, the hook operation portion 40 pushes the receiving portion 43, which is one end of the obtuse hook 29 a, toward the rear, and makes the obtuse hook 29 a face in the direction of the arrow, that is, toward the arrow. Turn in the opening direction and set it to "handle operation state". If the operation handle 30 is further pulled toward the front side, the engagement between the obtuse-angle hook 29a and the hook receiving means 37a is maintained in a released state, and therefore, as shown in FIG. 12, the cover can be closed. 7 Open towards the front side.

<Closed state>

When the cover body 7 is closed, the obtuse-angle hook 29a is closed with the hook in the closing position by the force of the closing direction caused by the torsion spring 42a. The segment 37a bites and merges into a "closed state" in which the lid body 7 is closed. At this time, the acute-angle hook 29b is located in the open position by the force of the return spring 42b, and does not act on the hook receiving means 37b.

"Opening force from inside caused by obtuse angle locking"

The force for opening the cover 7 from the inside in the "closed state" will be described. In the "closed state", as shown in Fig. 5 (a), the obtuse-angle hook 29a is locked to the hook receiving means 37a. When the opening force is applied from the inside of the cover 7 in this state, a force is applied in the direction of the arrow from the second support shaft 41 toward the front. The angle α 2 of the hook portion that connects the second support shaft 41 from the engaging surface between the obtuse-angle hook 29 a and the hook receiving means 37 a is, for example, an obtuse angle of about 105 °, so it is When a forward force is applied, a rotational force in a direction to open the obtuse-angle hook 29a is generated.

That is, if a certain amount of force is applied toward the front, and the force in the opening direction of the obtuse hook 29a becomes greater than the force in the closing direction caused by the torsion spring 42a, the obtuse hook 29a rotates, and the hook The engaging system between the receiving means 37a is disengaged, and the cover 7 is opened.

If the angle α 1 of the hook portion of the obtuse-angle hook 29a is made larger, the obtuse-angle hook 29a becomes easier to disengage. Therefore, it can be opened from the inside even with a smaller force. That is, by appropriately selecting the angle α1, the force for opening the lid body 7 from the inside can be appropriately set. This force can be set to 70N or less, for example.

〈Locked by Acute Angle Hook〉

Next, if the "locked state" is explained, it is a state in which the acute-angle hook 29b as shown in Fig. 5 (b) is closed and engaged with the hook receiving means 37b.

The angle α 1 of the hook portion that connects the second support shaft 41 from the engaging surface between the acute-angle hook 29 b and the hook receiving means 37 b is set to, for example, an acute angle of about 88 °. Therefore, even if the opening force is applied from the inside of the cover 7 toward the front, the acute-angle hook 29b will generate a force in the closing direction relative to the hook receiving means 37b. Therefore, the system will not leave the ground. The "locked state" in which the lid body 7 is closed is reliably maintained. That is, even if the cover 7 is subjected to the opening force from the inside during the washing process and even the drying process due to the warm air of the clothes 6 or high pressure, it can be reliably maintained in the cover. The body 7 is closed to prevent leakage of water or warm air, and to prevent the cover 7 from being opened unexpectedly during operation.

The opening force from the inside can be set to 300N or more, for example.

<The magnitude of the closing force caused by the two hooks>

That is, in the present embodiment, two locking hooks 29a and 29b are provided, and the angle is lower than the obtuse angle in a state in which the oblique-angle hook 29a is activated when the cover 7 is closed. The force that pushes the lid body 7 from the inside until the hook 29a is released "is" in a state where the lid body 7 is closed and the acute-angle hook 29b is activated, until the acute-angle hook 29b is The force "to push the cover 7 from the inside until it is released" is large.

〈Locking hook control method〉

Next, referring to FIG. 13 to FIG. 21, for the "locking operation" to move from the "closed state" in which the cover body 7 is closed to the "locked state" and to the "locked state", An example of the configuration of the latching hook control means 38 of the "lock-release operation" in the "closed state" will be described.

Then, the obtuse-angle hook slide member 47 is prevented from moving to the right, and the obtuse-angle hook slide member 47 is latched to keep the obtuse-angle hook 29a from opening.

The cam pin 61 is moved to the left along the crank groove 62 of the housing to the maximum, and the acute-angle hook sliding member 46 is moved to the left to maximize the movement of the acute-angle hook 29b to the closed position. With the acute-angle hook 29b, the setting change lever 49 is also moved to the left as far as possible, and the electrode front end portion 82 is moved to the left. The electrode (C) 80 and the electrode (D) 81 are connected, and the electrode plate ( B) 76 and electrode plate (C) 77 are short-circuited. The contact cam portion 63 of the sliding member 59 is in contact with the electrode protrusion 84 and moves the electrode (A) 78 to the left to contact the electrode (B) 79. The electrode (A) 78 and the electrode (B) 79 The system is turned on, and the electrode plate (A) 75 and the electrode plate (B) 76 are short-circuited.

In the "locked state", the cover is latched and held while the obtuse-angle hook 29a and the hook-receiving means 37a are engaged, and the acute-angle hook 29b and the hook-receiving means 37b are engaged to cover the cover. The body 7 is hermetically closed, and the cover 7 is in a state where it cannot be opened from the inside. Therefore, there is no internal pressure caused by the cover 7 from the clothes 6 or warm air in the laundry process or the drying process. As a result, the cover 7 is opened or leaks.

By moving the acute-angled hook slide member 46 to the right, and by the acute-angled hook 29b, the setting change lever 49 moves to the right by a reaction force in the right direction from the electrode tip portion 82. Further, the sliding member 59 is lowered, the contact cam portion 63 is separated from the electrode protrusion 84, and the electrode (A) 78 is moved to the right. If the driving pin 93 is further turned clockwise, it returns to the "closed state" shown in FIG. 18, and the electrodes (A) 78 and (B) 79 are separated from each other, and the electrode plate (A) 75 and the electrode The plates (B) 76 are insulated from each other. The electrode (C) 80 and the electrode (D) 81 are separated from each other, and the electrode plate (B) 76 and the electrode plate (C) 77 are insulated from each other.

The locking hook control means 38 in this embodiment is changed from the "closed state" to the "locked state" through the "locking action", and performs washing and even drying processes. After the washing and even the drying process is completed, it is possible to perform a series of actions from the "locked state" to the "closed state" through the "locked unlocking action".

<Construction with obtuse hook only>

In addition, in the "locked state", even if it is assumed that the structure is held in a locked state in which only the obtuse hook 29a is latched without the acute-angle hook 29b, the acute-angle hook sliding member 46 is also used. Since it is latched so that it does not move to the right, even if the opening force is applied from the inside of the cover body 7, it will not be easily opened. However, since the tip end of the hook is an obtuse angle, the opening force from the inside of the cover body 7 generates a force in the direction in which the obtuse angle hook 29a is opened. Therefore, when the force capable of maintaining the locked state is exceeded, the obtuse-angle hook 29a and the obtuse-angle hook sliding member 47 or the resin components such as the housing 44 and 45 are deformed, and the obtuse-angle hook 29a is locked. It may become slack or detach from the receiving means 37a, 37b.

That is, if the rotating drum 11 is made larger by increasing the capacity of the washer-dryer, it becomes possible to wash a greater amount of laundry 6. For example, when washing a blanket or quilt, In the washing process or the drying process, there may be a case where a strong opening force higher than that of the prior art is applied to the cover 7 from the inside. In addition, in order to increase the ease of taking out the clothes 6, the cover 7 is made larger in size. At the same time, in accordance with the expansion of its area, the lid 7 is applied with a strong opening force higher than that of the prior art from the inside. Therefore, in the configuration having only the obtuse-angle hook 29a, it is necessary to maintain the lock. There is a limit to the state of death.

Or, when washing the laundry with the above-mentioned amount of washing water and performing so-called high-water washing, stagnant water washing, etc., the water level becomes more than the boundary between the cover body 7 and the bellows tube 31. In the case of general laundry and even cleaning processes above, since it is a watertight structure that requires stronger, there is a limit to preventing water leakage in a structure having only obtuse hooks 29a.

Also, when a high-pressure fan is used as the air supply means, and high-temperature and high-temperature warm air is used to shorten the drying time or increase the completion of the drying, the same is true for the cover body 7 and There is a limit to the relaxation between the bellows tubes 31 and the improvement of air tightness.

In this embodiment, in the "locked state", the acute angle hook 29b is locked at the hook receiving means 37b. Therefore, even if the opening force is applied to the cover 7 from the inside, Since a force is generated in the direction of opening the acute-angle hook 29b, the locking of the cover body 7 becomes reliable, and a washing and drying machine having high reliability can be provided.

<Two ticks>

In the "closed state", since the obtuse-angle hook 29a is locked only as shown in Fig. 5 (a), the cover is pushed from the inside When the body 7 pushes the second support shaft 41 forward, a momentum is generated in the direction that opens the obtuse-angle hook 29a from the hook receiving means 37a. Therefore, the obtuse-angle hook 29a is caused by a specific force. The cover 7 is turned counterclockwise as shown in the figure and detached from the hook receiving means 37a, and the cover 7 is opened.

Here, if the obtuse angle α 1 of the hook angle of the obtuse hook 29 a is smaller and closer to a right angle, the force system required to open the cover 7 becomes larger. If the obtuse angle α 1 is larger, the opening direction As the momentum system becomes larger, the specific force system required to open the lid 7 becomes smaller, and the lid 7 becomes easier to open. The obtuse angle α 1 can be appropriately selected in such a manner that the cover 7 will be opened if a specific force is applied to the cover 7 from the inside.

In the "locked state", as shown in FIG. 5 (b), the acute angle hook 29b is locked in addition to the obtuse angle hook 29a. Because the hook angle is an acute angle α 2, even when the second support shaft 41 is pushed forward, no momentum in the opening direction is generated at the acute angle hook 29b. Therefore, in the laundry process, In the drying and drying process, there is no reason that the lid 7 is opened during operation due to the internal pressure that the lid 7 receives from the clothes 6 or warm air, or is caused by the bellows tube 31 and the door glass 32. Watertightness is reduced and water leakage occurs, and a drum-type washer-dryer with high reliability can be provided.

<Forced release action>

Next, using FIG. 22 and FIG. 23, for the “locked state” in which the lid body 7 is locked, the lid body 7 is forcibly set to a “forced” state that can be opened. "Release action".

For example, when the washing and drying machine is stopped due to a power failure during the washing process or the drying process, the locking hook control means 38 is maintained in a "locked state" and the clothes 6 cannot be taken out.

FIG. 22 shows a state where the forcible release band 48 is pulled downward in the “locked state”. The forcible release band 48 is attached to the belt protrusion 70 of the rocking plate 64 via the belt guide member 71. Therefore, if the forcible release band 48 is pulled downward, the rocking plate 64 faces the clockwise direction as shown in the figure. When rotated, the driving pin 93 moves along the lower edge 68 of the L-shaped groove 69 to the bent portion 95.

FIG. 23 shows a state where the forcible release band 48 is pulled further downward. The rocking plate 64 is pulled and lowered by the forcible release belt 48, and the driving pin 93 is moved to the vicinity of the upper end of the L-shaped groove 69. The cam pin 61 is also lowered, and the acute-angle hook sliding member 46 is moved to the right to move the acute-angle hook 29b to the open position. As a result, only the obtuse-angle hook 29a is closed.

Since the acute-angle hook 29b is in the open position and the obtuse-angle hook 29a is in the closed position, it is in the same state as the "closed state" shown in FIG. The hook 29a is moved from the closed position to the open position, and the cover 7 is opened.

That is, when the washer-dryer is stopped in the "locked state", the forced release belt 48 is pulled downward. By pulling and operating the operation handle 30 in this state, the cover 7 can be opened and the clothes 6 can be taken out.

<alarm>

Next, a case where the hook control means 38 detects an abnormality and sends an alarm will be described with reference to FIGS. 24, 25, and 26.

Fig. 24 shows a case where the washing and drying machine is intended to be operated with the lid 7 still open, and Fig. 25 shows a case where the obtuse-angle hook 29a is broken. Fig. 26 shows an acute angle. Hook 29b is broken for demonstration.

In FIG. 24, since the lid body 7 is in the opened state, the acute-angle hook 29 b does not enter the acute-angle hook slide member 46 and the obtuse-angle hook 29 a does not enter the obtuse-angle hook slide member 47. Therefore, the obtuse-angle hook slide member 47 is positioned at the position most to the right in the figure by the reaction force of the first pressing member 52.

When the cover 7 is opened and the user presses the start switch of the washing process or even the drying process, the motor 85 is rotated to move to the "locked state", and the driving pin 93 is driven. The system is turned clockwise to move the rocking plate 64 and the sliding member 59 upward. In this way, the upper end of the sliding member 59 is in contact with the lower surface of the latch receiving protrusion 53 provided at the right end of the obtuse-hook sliding member 47, and further moves upward toward the rocking plate 64 and the sliding member 59. Make obstacles. In this way, since the contact cam portion 63 provided at the sliding member 59 does not contact the electrode protrusion 84, the electrode (A) 78 and electrode (B) 79 are not connected. Therefore, the electrode plate (A) 75 and the electrode plate (B) 76 are maintained in a separated state and remain OFF. As shown in FIG. 20, in the "locked state", the electrode plate (A) 75 and the electrode plate (B) 76 are short-circuited. However, when the cover 7 is opened, the There is no short circuit for a certain time and it remains in the OFF state. Therefore, it is judged that the normal "lock-up action" has not been performed, and an alarm is generated.

Therefore, since the lid 7 is opened, even if the user presses the start switch of the laundry process or even the drying process, the alarm will be generated. Therefore, the lid 7 will not be opened. When a washing process or a drying process is started in a state, a washing machine capable of providing reliable operation and high reliability can be provided.

In Fig. 25, the action when the hook portion of the obtuse-angle hook 29a is broken is shown. Although the obtuse-angle hook 29a is in the closed position, the front-end hook portion is broken as shown by the dashed line. Therefore, the obtuse-angle hook slide member 47 does not face the left as in the "closed state" shown in FIG. When moving, the obtuse-angle hook slide member 47 is positioned to the right by the reaction force of the first pressing member 52.

Therefore, as explained in FIG. 24, the sliding member 59 is abutted under the latch receiving protrusion 53 and does not move all the way to the upper end. The electrode plate (A) 75 and the electrode plate (B) 76 are Maintained in a separated state, even if a certain period of time elapses, it will not become a short circuit and remains in the OFF state. Therefore, it is judged that the normal "lock operation" is not performed, and an alarm is generated.

Therefore, in the state where the hook portion of the obtuse-angle hook 29a is damaged, even if the user presses the start switch of the laundry process or even the drying process, the alarm will be issued. Therefore, there will be no obtuse-angle hook 29a. When the hook part is broken, the washing process or the drying process is performed, and a washing machine with reliable operation and high reliability can be provided.

In FIG. 26, when the hook portion of the acute-angle hook 29b is broken, the motor 85 rotates in the same manner as in FIG. 20 and moves to the “locked state”, and the driving pin 93 is clockwise. By turning, the acute-angle hook slide member 46 is moved to the left as in the "locked state" shown in FIG. 20.

Although the acute-angle hook 29b is located in the closed position, the front end hook portion is broken as shown by the dotted line. Therefore, the setting change lever 49 that operates by the acute-angle hook 29b does not move to the left. Therefore, by setting The electrode tip portion 82 series moved by changing the groove portion 58 does not move to the left, and the electrodes (C) 80 and (D) 81 series are maintained in a separated state from each other, and are not kept in an OFF state without being short-circuited. Therefore, it is determined that the normal "locking action" has not been performed, and an alarm is generated.

Therefore, in the state where the hook portion of the acute-angle hook 29b is damaged, even if the user presses the start switch of the laundry process or even the drying process, the alarm will be issued. Therefore, there will be no acute-angle hook 29b. When the hook part is broken, the washing process or the drying process is performed, and the operation can be provided with reliability and reliability. Washing machine.
