At the second support shaft 41, a torsion spring 42b is coaxially disposed, and is oriented toward the direction in which the acute angle hook 29b is opened, that is, from the hooking control means 38. The direction separated by means 37b is pushed.

8 and FIG. 10 are similar to FIG. 5(a), and are shown in a "sealed state" in which the obscuration hook 29a is placed in a closed position and fitted to the hook receiving means 37a to seal the lid 7. At this time, the acute angle hook 29b is in the open position.

<opening and releasing the action>

When the lid body 7 is opened from the "sealed state" when the laundry 6 is moved in and out, the operation handle 30 is operated as shown in FIGS. 6 to 7.

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

As shown in FIG. 9 and FIG. 11, the locking hook operating portion 40 presses the receiving portion 43 which is one end of the obtuse hook 29a toward the rear, and causes the obtuse hook 29a to face the direction of the arrow, that is, the direction. Turn in the opening direction and set to "handle operation status". 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 the released state. Therefore, as shown in Fig. 12, the cover can be used. 7 opens toward the front side.

<Closed state>

When the cover body 7 is closed, the obtuse angle hook 29a is biased by the torsion spring 42a in the closing direction, and is closed at the closed position. The segment 37a is bitten and joined to form a "sealed state" in which the lid body 7 is sealed. At this time, the acute angle hook 29b is 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 the inside caused by the obtuse angle lock>

The force which opens the lid body 7 from the inside in the "sealed state" will be described. In the "sealed state", as shown in Fig. 5 (a), the obtuse angle hook 29a is in a state of being locked by the hook receiving means 37a. When the opening force is applied from the inside of the lid body 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 connecting the second support shaft 41 from the engagement surface between the obtuse angle hook 29a and the hook receiving means 37a is an obtuse angle of, for example, 105 degrees, and therefore If a force toward the front is applied, a rotational force in a direction in which the obtuse hook 29a is opened is generated.

In other words, if a force of a specific force or more is applied to the front side and the force in the direction in which the obtuse angle hook 29a is opened is larger than the force in the closing direction by the torsion spring 42a, the obtuse angle hook 29a is rotated, and the hook is hooked. The engagement between the receiving means 37a is released, and the cover 7 is opened.

If the angle α 1 of the hook portion of the obtuse hook 29a is made larger, the obtuse hook 29a is more easily detached, so that it can be opened from the inside even with a smaller force. That is, by appropriately selecting the angle α 1, it is possible to appropriately set the force for opening the lid body 7 from the inside. This force can be set, for example, to be 70 N or less.

<Locked state caused by sharp angle hook>

Next, in the case of the "locked state", the acute angle hook 29b as shown in Fig. 5 (b) is in a closed position and is engaged with the hook receiving means 37b.

The angle α1 of the hook portion connecting the second support shaft 41 from the engagement surface between the acute angle hook 29b and the hook receiving means 37b is set to an acute angle of, for example, about 88 degrees. Therefore, even if the force is applied from the inner side of the lid body 7 to the front, the force of the closing direction is further generated by the acute angle hook 29b with respect to the hook receiving means 37b. Therefore, the force does not come off. It is surely maintained as a "locked state" in which the lid body 7 is closed. In other words, even if the cover body 7 is opened from the inside even if it is caused by the warm air of the clothes 6 or the high pressure during the operation of the washing process or the drying process, the cover can be surely maintained. The body 7 is in a closed state to prevent leakage of water or warm air, and further prevents the cover 7 from being unexpectedly opened during operation.

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

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

In other words, in the present embodiment, two hooking hooks 29a and 29b are provided, and the angle is until the obtuse angle is in a state in which the obtuse hook 29a is activated when the lid body 7 is closed. "The force that pushes the lid body 7 from the inside until the hook 29a is released" is "in the state where the lid body 7 is closed and the acute angle hook 29b is actuated until the acute angle hook 29b is The force for pressing the lid body 7 from the inside until the release is large.

<Lock control method>

Next, with reference to FIGS. 13 to 21, the "locking operation" from the "sealed state" in which the lid body 7 is sealed to the "locked state" and the "locking state" are moved to An example of the configuration of the hook check control means 38 of the "lock release operation" in the "closed state" will be described. In addition, in addition to FIGS. 16 and 17, the upper casing 44 is omitted and only the lower casing 45 is illustrated in order to easily understand the internal configuration.

That is, when the lid body 7 is closed, the obtuse angle hook 29a is bitten by the hooking means 37a at the closed position by the force of the closing direction caused by the torsion spring 42a to become the lid body. 7 made a closed "closed state". Here, the pressing force in the opening direction caused by the first pressing member 52 is smaller than the force in the closing direction of the obtuse angle hook 29a by the torsion spring 42a.

As shown in Fig. 17 (b), in the case where the operation handle 30 is operated and the "handle operation state" is set to "open state", the obscuration hook 29a is locked from the hook receiving means 37a. When the pressure is caused by the first pressing member 52, the obtuse hook sliding member 47 moves to the right.

The other end of the second pressing member 73 is pressed toward the second spring receiving portion 74 provided at the lower casing 45.

<Control electrode>

Further to the left side of the rocking plate 64 or the sliding member 59, from the side close to the sliding member 59, the electrode plate (A) 75, the electrode plate (B) 76, and the electrode plate (C) are sequentially disposed. 77. The control signal of the hook control means 38 is sent out by detecting ON or OFF caused by short circuit and insulation between the electrode plates.

At the vicinity of the upper end of the electrode plate (A) 75, an electrode (A) 78 which is convex toward the left is provided, and at a lower position than the electrode (A) 78, it is provided to protrude toward the direction close to the sliding member 59. The electrode protrusion 84 and the electrode protrusion 84 are configured to abut the contact cam portion 63 in a specific range in the vicinity of the upper end.

The electrode plate (B) 76 is located at the vicinity of the upper end and is divided into two. At the right side plate adjacent to the sliding member 59, an electrode (B) 79 is disposed at a position opposite to the electrode (A) 78, and When the electrode projection 84 is pressed to the left by the contact cam portion 63, the electrode plate (A) is bent toward the left, and the electrode (A) 78 is in contact with the electrode (B) 79.

The electrode plate (C) 77 is provided with an electrode (D) 81 at a position opposed to the electrode (C) 80.

The electrode tip end portion 82 which is the upper end of the left side plate of the electrode plate (B) 76 is fitted into the setting change groove portion 58 provided in the setting change lever 49 with a gap. At the setting change lever 49, the pressing force toward the right is applied via the electrode tip end portion 82 by the spring property of the left side plate of the electrode plate (B) 76. The configuration is such that when the acute angle hook 29b is in the open position and the setting change lever 49 is moved to the right, the electrode (C) 80 and the electrode (D) 81 are separated from each other, and when the acute angle hook 29b is in the closed position and set When the change lever 49 is moved to the left, the electrode tip end portion 82 is bent toward the left side, the electrode (C) 80 is in contact with the electrode (D) 81, and the electrode plate (B) 76 and the electrode plate (C) 77 are attached. It becomes a short circuit.

<Drive means>

The drive means 83 is provided with a pinion 87 at a motor shaft 86 which is an output shaft of a motor 85 as a drive source, and transmits the output torque of the motor 85 to the outside. The first gear 88 having a smaller number of teeth 87 and a smaller gear 87 is engaged with the pinion gear 87 and rotates around the idler shaft 89 while rotating, and the number of teeth is less than that of the first gear 88. The wheel 90 is rotated integrally with the first gear 88. The third gear 91 having a larger number of teeth than the second gear 90 is engaged with the second gear 90 and is rotated around the drive shaft 92 while being decelerated, and the eccentricity of the distance r from the drive shaft 92 is made. The drive pin 93 is provided to rotate around the drive shaft 92. In the present embodiment, the drive pin 93 is rotated clockwise in the drawing. The drive pin 93 is fitted and rotated by the lower side 68 of the L-shaped groove 69 provided at the rocking plate 64. Therefore, when the motor 85 is rotationally driven, the drive pin 93 is rotated while being decelerated and transmitted. The L-shaped groove 69 moves the rocking plate 64 and the sliding member 59 by a distance 2r in the vertical direction to move the cam pin 61 along the outer casing crank groove 62. The movement of the cam pin 61 along the crank case groove 62 is converted into the left-right direction movement of the acute-angle hook sliding member 46 through the crank groove 56, and the opening and closing operation of the acute-angle hook 29b is performed.

<Summary of Sharp Angle Hook Slider>

In other words, the sliding member 59, the rocking plate 64, the crank case 62, and the crank groove 56 that move in the up-and-down direction are transmitted by the action of the driving pin 93 driven by the motor 85, thereby making the acute angle The hook sliding member 46 is moved in the left-right direction, and the opening and closing operation of the acute-angle hook 29b is performed.

<Summary of obtuse angle hook sliding members>

On the other hand, the obtuse hook sliding member 47 is not configured to operate by the transmission motor 85 and the drive pin 93, but is configured to: cover the cover 7 When the opening is performed, the first pressing member 52 is moved in the right direction. When the lid 7 is closed, the hook portion near the front end of the obtuse hook 29a is inserted into the obtuse hook sliding member 47. In the recess 50, the obtuse hook 29a is moved in the left direction by the force in the closing direction of the torsion spring 42a, and the obtuse hook 29a is closed, and the obtuse hook 29a is operated by the opening operation of the handle 30. Turn on the action.

In the present embodiment, the first locking hook (obtuse hook) 29a that can be opened and closed by the operation of the handle 30 is provided, and the motor 85 can be provided by the locking hook control means 38. The driving means is used to open and close the second locking hook (an acute angle hook) 29b.

Next, a suitable shape for the outer crank groove 62 and the crank groove 56 provided at the acute hook sliding member 46 will be described using FIG.

As in the previous description, the sliding member 59 is configured to perform the distance 2r in the up and down direction, and the movement direction is converted into the left and right direction of the acute angle hook sliding member 46, so that the acute angle hook sliding member 46 is formed. Make the movement of the distance (e1+e2). Set the angle of the bent portion of the outer crank groove 62 to 1, and set the angle of the bent portion of the crank groove 56 to 2.

Here, for example, if the straight groove of the vertical direction of the crank groove 62 is set to the vertical direction and the direction is changed only by the crank groove 56, the angle of the bent portion of the crank groove 56 is not obtained. 2' increase to about 2'=( 1+ 2) The degree of movement of the acute-angle hook sliding member 46 may become insufficient. As a result, the contact angle between the cam pin 61 and the crank groove 56 becomes Since 2' is increased, the friction load is increased, and the load required for moving the acute-angle hook sliding member 46 is increased, or the friction load is large and the operation cannot be performed.

Therefore, by bending the angle of the bent portion of the outer crank groove 62 1 and the angle of the bend of the crank groove 56 2 is set to be substantially equal, and e1 and e2 are set to be substantially equal, since the contact angle with the cam pin 61 can be prevented. 1 or even The increase of 2 prevents the increase of the friction load, so that the lock action and the lock release action are stable, and the laundry dryer having high reliability can be provided.

<Card check control action>

18 to 21 are front views for explaining the operation of the locking hook control means 38, and Fig. 18 is a display for "closed state" in which the cover is closed and only the obtuse angle is locked. 19 is a display of the "locking action" in the middle of the operation in which the acute angle hook 29b is moved from the "open state" to the "locked state" by moving the acute angle hook 29b from the open position to the closed position. Fig. 20 shows the "locked state" which acts on the acute angle hook 29b and locks the cover body 7, and Fig. 21 is for "locking up" from gradually locking the acute angle hook 29b. The "locked release action" that is released is released.

<Closed state> Figure 18

In the "closed state" of Fig. 18, the drive pin 93 is located in the figure. The lower end abuts against the lower side 68 of the L-shaped groove 69 provided at the rocking plate 64, and the rocking plate 64 and the sliding member 59 are positioned at the lowermost position. The cam pin 61 is located at the lowermost portion of the crank case groove 62 and the crank groove 56. The acute angle hook sliding member 46 is positioned to move to the rightmost position, and the acute angle hook 29b is moved to the right and is in the open position. .

In the "sealed state", if the operation handle 30 is operated, the obtuse hook 29a is opened, and the cover 7 can be opened and the laundry 6 can be taken out or the laundry 6 can be taken out.

As in the above description, in this state, if the lid body 7 is pressed from the inner side by a specific force or more, the obtuse angle hook 29a is detached, and the lid body 7 can be opened.

<Locking action in the middle> Figure 19

Fig. 19 is a view showing a "locking action" in which the motor 85 is driven from the "sealed state", and is shown in a state in which the driving pin 93 is rotated 90° clockwise from the lower end. The driving pin 93 is moved to the left along the lower edge 68 of the L-shaped groove 69, and the rocking plate 64 is moved upward by the driving pin 93, and the cam pin 61 is oriented upward and toward the left along the crank groove 62 of the casing. As the square moves, the acute-angle hook sliding member 46 moves toward the left and moves the acute-angle hook 29b toward the closing direction. By moving the acute-angle hook sliding member 46 to the left, the setting change lever 49 is moved to the left by the acute-angle hook 29b, and the electrode tip end portion 82 is moved to the left by setting the change groove portion 58, therefore, the electrode The (C) 80 series approaches the electrode (D) 81.

<Locked state> Figure 20

Fig. 20 is a view showing the "locked state" and showing a state in which the driving pin 93 is rotated from the lower end toward the clockwise direction by 180° and at the upper end. The rocking plate 64 is moved to the upper end by the driving pin 93 which is moved along the lower side 68 of the L-shaped groove 69, and is further oriented by the second pressing member 73 which is a compression spring. Push it up. The sliding member 59 is also moved to the upper end by the driving pin 93, and the latch portion 94 provided at one portion of the sliding member 59 is brought toward or close to the latching projection 53 of the obtuse hook sliding member 47. Then, the movement toward the right of the obtuse-angle hook sliding member 47 is hindered, and the obtuse-angle hook 29a is kept from being opened by the latching of the obtuse-angle hook sliding member 47.

The cam pin 61 is moved to the left along the outer crank groove 62 to the maximum extent, and the acute hook sliding member 46 is moved to the left to maximize the movement and the acute angle hook 29b is moved to the closed position. With the acute angle hook 29b, the setting change lever 49 is also moved to the left for maximum movement, and the electrode tip end portion 82 is moved to the left side, and the electrode (C) 80 and the electrode (D) 81 are electrically connected, and the electrode plate ( B) 76 and the electrode plate (C) 77 are short-circuited. Further, the contact cam portion 63 of the sliding member 59 abuts against the electrode protrusion 84, and moves the electrode (A) 78 to the left to abut against the electrode (B) 79, and the electrode (A) 78 and the electrode (B) 79 When it is turned on, the electrode plate (A) 75 and the electrode plate (B) 76 become short-circuited.

In the "locked state", the obtuse hook 29a is latched and held in a state in which the hooking means 37a is engaged, and the acute angle hook 29b is engaged with the hook receiving means 37b to cover the cover. The body 7 is sealed, and the cover 7 is in a state in which it cannot be opened from the inside. Therefore, there is no internal pressure caused by the cover 7 from the clothes 6 or the warm air in the laundry or drying process. This causes the cover 7 to open or leak.

<Unlocking the way in progress> Figure 21

Fig. 21 shows the "lock release operation" from the "locked state" to the "closed state", and the position of the drive pin 93 is 270 degrees from the lower end toward the clockwise direction. The state of the place is displayed. The rocking plate 64 is lowered by the driving pin 93, and the cam pin 61 is moved to the right along the outer crank groove 62, and the acute-angle hook sliding member 46 is moved to the right to move the acute-angle hook 29b toward the opening direction. By moving the acute-angle hook sliding member 46 to the right, the setting change lever 49 is moved to the right by the reaction force in the right direction from the electrode tip end portion 82 by the acute-angle hook 29b. 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 drive pin 93 is further rotated in the clockwise direction, it returns to the "sealed state" shown in Fig. 18, and the electrode (A) 78 and the electrode (B) 79 are separated from each other, and the electrode plate (A) 75 and the electrode are separated. The plates (B) 76 are insulated from each other. Further, 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.

In the lock state control means 38 of the present embodiment, the "locking operation" is performed from the "sealed state" to become the "locked state", and the laundry or drying process is performed. After the washing and even the drying process is completed, it is possible to perform a series of operations from the "locked state" to the "closed state" after the "lock release operation".

<The composition of only obtuse angle hooks>

Further, in the "locked state", even if it is assumed that the acute angle hook 29b is not provided and the lock is held by the hook state of the obtuse hook 29a, the acute angle hook sliding member 46 is also used. Since the latch is lifted so as not to move to the right side, even if an opening force is applied from the inner side of the cover 7, it is not easily opened. However, since the front end of the hook is an obtuse angle, a force which is opened from the inner side of the lid body 7 causes a force in a direction in which the obtuse angle hook 29a is opened. Therefore, when the force which can be maintained at the limit of the locked state is exceeded, the obtuse hook 29a and the obtuse hook sliding member 47 or the resin component parts such as the outer casings 44 and 45 are deformed, and the obtuse hook 29a is locked. There may be cases where it becomes slack or is detached from the means 37a, 37b.

In other words, when the rotary drum 11 is increased in size with the increase in the capacity of the washing and drying machine, it is possible to wash a larger amount of the laundry 6, for example, when washing the felt or the quilt. In the laundry or drying process, there is a case where a strong opening force of the prior art or more is applied to the lid 7 from the inside. Moreover, in order to increase the ease of taking out the clothes 6, the cover body 7 is further enlarged. In the same manner, in view of the expansion of the area thereof, since the strong opening force of the prior art or more is applied to the lid body 7 from the inner side, in the configuration having only the obtuse angle hook 29a, the lock is maintained. There is a limit to the state of death.

Alternatively, when the laundry water of the prior art is supplied at the time of washing and subjected to a so-called high water level washing, water washing, etc., the water level becomes a boundary between the cover body 7 and the bellows tube 31. In the case of the general laundry above and even the washing process, since it is a structure requiring a stronger watertight structure, in the configuration having only the obtuse angle hook 29a, there is a limit to prevent water leakage.

Further, in the case where a high-pressure fan is used as the air blowing means, and the drying time is shortened by the high-temperature high-temperature warm air or the completion degree of the drying is improved, the same applies to the prevention of the cover body 7 and There is a limit to the relaxation between the bellows tube 31 and the improvement of airtightness.

In the present embodiment, since the acute angle hook 29b is locked to the hook receiving means 37b in the "locked state", even if the opening force is applied to the lid body 7 from the inside, it does not occur. Since the force in the direction in which the acute angle hook 29b is opened is generated, the locking of the lid body 7 is made reliable, and a washing and drying machine having high reliability can be provided.

<2 hooks>

In the "sealed state", since only the obtuse hook 29a is locked as shown in Fig. 5(a), the cover is pushed from the inside. When the body 7 presses the second support shaft 41 toward the front side, the momentum of the obtuse angle hook 29a in the direction in which the obtuse angle hook 29a is opened from the hook receiving means 37a is generated. Therefore, the obtuse angle hook 29a is used by the specific force. The body is rotated counterclockwise in the drawing and is detached from the hook receiving means 37a, and the lid body 7 is opened.

Here, if the obtuse angle α 1 of the hook angle of the obtuse angle hook 29a is smaller and closer to a right angle, the force required to open the lid body 7 becomes larger, and if the obtuse angle α 1 is larger, the opening direction is larger. Since the momentum is increased, the specific force required to open the lid 7 is reduced, and the lid 7 is easily opened. It is possible to appropriately select the obtuse angle α 1 in such a manner that the lid body 7 is opened by a specific force from the inside.

In the "locked state", the acute angle hook 29b is locked in addition to the obtuse angle hook 29a as shown in Fig. 5(b). Since the angle of the hook portion is an acute angle α 2, even when the second support shaft 41 is pressed toward the front, the momentum in the opening direction is not generated at the acute angle hook 29b, and therefore, in the laundry engineering In the drying and drying process, there is no internal pressure caused by the cover body 7 from the clothes 6 or the warm air, which causes the cover body 7 to be opened during operation or caused by the bellows tube 31 and the door glass 32. The watertightness is reduced and water leakage occurs, and a drum type washing and drying machine having high reliability can be provided.

<Forced release action>

Next, with reference to Fig. 22 and Fig. 23, it is mandatory to make the lid body 7 openable from the "locked state" in which the lid body 7 is locked. "Remove action" for explanation.

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

Fig. 22 shows a state in which the forcible release belt 48 is pulled downward in the "locked state". Since the forcible release belt 48 is tied to the belt projection 70 of the rocking plate 64 via the belt guide member 71, if the forcible release belt 48 is pulled downward, the swinging plate 64 is oriented clockwise in the drawing. Rotating, the drive pin 93 is moved along the lower edge 68 of the L-shaped groove 69 to the bent portion 95.

Fig. 23 shows a state in which the forcible release belt 48 is pulled further downward. The rocking plate 64 is pulled and lowered by the forcible release belt 48, and the drive pin 93 is moved all the way to 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, and as a result, only the obtuse-angle hook 29a is closed.

Since the acute angle hook 29b is the open position and the obtuse angle hook 29a is the closed position, it is in the same state as the "sealed state" shown in Fig. 18. If the operation handle 30 is operated in this state, the obtuse angle is obtained. The hook 29a is moved from the closed position to the open position, and the cover 7 is opened.

That is, when the laundry dryer is stopped in the "locked state" position, the forced release belt 48 is pulled downward. When the operation handle 30 is operated in this state, the cover 7 can be opened and the laundry 6 can be taken out.

<alarm>

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

Fig. 24 is a view showing a case where the washing and drying machine is to be operated while the lid body 7 is still open, and Fig. 25 shows the case where the obtuse angle hook 29a is broken, and Fig. 26 is for an acute angle. The case where the hook 29b is broken is displayed.

In Fig. 24, since the lid body 7 is in an open state, the acute angle hook 29b does not enter the acute-angle hook sliding member 46 and the obtuse-angle hook 29a does not enter the obtuse-angle hook sliding member 47. Therefore, the obtuse-angle hook sliding member 47 is positioned to the right of the figure by the reaction force of the first pressing member 52.

When the user presses the start of the laundry process or the drying process in a state where the cover 7 is opened, the motor 85 is rotated to the "locked state", and the drive pin 93 is driven. The rotation is clockwise and the rocking plate 64 and the sliding member 59 are moved upward. As a result, the upper end of the sliding member 59 abuts against the lower surface of the latch receiving projection 53 provided at the right end of the obtuse hook sliding member 47, and further upward movement of the rocking plate 64 and the sliding member 59. Obstruction. As a result, since the contact cam portion 63 provided at the sliding member 59 does not abut against the electrode protrusion 84, the electrode Since the (A) 78 and the electrode (B) 79 are not in contact with each other, the electrode plate (A) 75 and the electrode plate (B) 76 are maintained in a state of being separated from each other and kept in an OFF state. As shown in Fig. 20, in the "locked state", the electrode plate (A) 75 and the electrode plate (B) 76 are short-circuited, but in the state in which the cover 7 is opened, even if it passes through The specific time is also not short-circuited and remains in the OFF state. Therefore, it is determined that the normal "lock-up operation" has not been performed, and an alarm is generated.

Therefore, when the lid body 7 is opened, even if the user presses the washing machine or even the start switch of the drying process, an alarm is generated, so that the lid body 7 is not opened. In the state where the operation of the laundry or drying operation is started, it is possible to provide a washing machine having an action that is reliable and high in reliability.

In Fig. 25, the operation in the case where the hook portion of the obtuse hook 29a is broken is shown. Although the obtuse hook 29a is in the closed position, since the front end hook portion is broken as indicated by the broken line, the obtuse hook sliding member 47 does not generally face the left side as in the "closed state" shown in FIG. When moving, the obtuse-angle hook sliding member 47 is positioned to the right by the reaction force of the first pressing member 52.

Therefore, as generally illustrated in Fig. 24, the sliding member 59 abuts against the underside of the latch receiving projection 53 and does not move all the way to the upper end, and the electrode plate (A) 75 and the electrode plate (B) 76 are attached. Since it is maintained in a state of being separated from each other, even if it is a certain period of time, it does not become a short circuit and remains in the OFF state. Therefore, it is determined that the normal "locking operation" has not been performed, and an alarm is generated.

Therefore, in the state where the hook portion of the obtuse hook 29a is broken, even if the user presses the laundry or even the start switch of the drying process, an alarm is issued, so that there is no obtuse hook 29a. When the hook portion is broken and the laundry or drying operation is performed, it is possible to provide a washing machine having an accurate operation and high reliability.

In the state in which the hook portion of the acute-angle hook 29b is broken, the motor 85 is rotated in the same manner as in Fig. 20 to the "locked state", and the drive pin 93 is oriented clockwise. When the rotation, the acute-angle hook sliding member 46 is moved to the left state in the same manner as the "locked state" shown in Fig. 20 .

Although the acute angle hook 29b is in the closed position, since the front end hook portion is broken as indicated by the broken line, the lever 49 is not changed to the left side by the setting of the operation of the acute angle hook 29b, and therefore, by setting The electrode tip end portion 82 that moves while changing the groove portion 58 does not move to the left side, and the electrode (C) 80 and the electrode (D) 81 are maintained in a state of being separated from each other, and are 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 of the acute angle hook 29b is broken, even if the user presses the laundry and even the start switch of the drying process, the alarm will be issued, so there is no sharp angle hook 29b. When the hook portion is broken and the laundry or drying operation is performed, the operation can be made reliable and the reliability is high. Washing machine.
