Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a door lock device for a washing machine for locking a door of a drum type washing machine or the like.

[0002]

2. Description of the Related Art Conventionally, a drum-type washing machine has been developed and used in Europe as a space-saving washing and drying machine capable of automatically performing washing, dehydration, and drying in a drum continuously and continuously. In such a drum type washing machine, as shown in FIG. 13, the opening 4 of the drum 3 installed inside the main body 2 is provided on the front side as an input port for taking in and out the laundry, and the drum input port 4 is opened and closed. Door 5 is also provided on the front side. The door 5 is provided with a claw 6, an opening 7 through which the claw 6 is inserted is provided in a wall surface of the main body 2, and a door lock device 8 is provided inside the wall surface. Is lockable.

For this reason, the door lock device 8 has, for example, an opening through which the pawl 6 enters and an engaging portion for locking the door pawl, which communicates with the wall opening 7 thereof, and is opposite to the direction in which the door pawl is locked. The lock mechanism includes a claw insertion member that is installed movably in a door claw lock release direction, and receives a biasing force in the door claw lock release direction, and a lock mechanism that locks the claw insertion member. An operating member having a door claw locking engaging portion corresponding to the door claw locking engaging portion of the claw inserting member, and being movably installed in a direction perpendicular to the moving direction of the claw inserting member; As a means for moving a member for door claw lock and door claw lock release, there is a device provided with a bimetal with a heater.

[0004]

However, when a bimetal with a heater is used as a means for moving the operating member of such a lock mechanism, the operation of the bimetal by the heater and the natural cooling of the bimetal is performed. , The start of movement of the operating member is delayed, and the reaction of unlocking the door claw is delayed. In addition, when a power failure occurs during washing or the like, the door claws are released and the door is opened.
Therefore, when the door 5 is opened at the time of washing or spin-drying, water in the drum (hereinafter referred to as tank water) comes out, and during drying, the door 5
When the door is opened, there is a danger that burns may be caused by putting hands into the drum slot 4 in an attempt to remove laundry by mistake. Therefore, in order to cope with a power failure during washing or the like, an air trap system has been added to provide a double lock system. In the air trap system, since the water pressure in the drum is detected and locked by using a diaphragm or the like, the door does not open even if power is interrupted during washing or the like.

[0005] In addition, there has been developed a type using a solenoid instead of a bimetal with a heater and having a lock mechanism for quickly moving an operation member upon locking and unlocking a door claw. However, since the moving direction of the claw insertion member and the moving direction of the operating member are the same direction, a large load is likely to be applied to the lock mechanism when the door in the locked state is forcibly opened. Therefore, there is a problem that the mechanical strength of the lock mechanism must be increased. Also, in order to keep the door in a locked state and prevent the door from being opened even if a power failure occurs during washing, a solenoid that is different from that used when the door claw is locked and when the door claw is unlocked is used to suck or push the operating member. is there.

In addition, as another lock device having only one solenoid, a door claw lock is performed by mechanically pushing an operation member, and the lock is released by electrically sucking the operation member by a solenoid. However, since the door is locked when the door is closed, even if the door is opened again and laundry is added before starting the washing, the door is not opened as it is. Therefore, opening the door requires other operations such as energizing the solenoid. In order to release the door lock of the door lock device provided with the solenoid at the time of power failure, the lock is released by pulling the operation member with a string.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. The operation of the lock mechanism is compact and the operation thereof is speeded up. An object of the present invention is to provide a door lock device for a washing machine that can release a door at the time of a power failure and that can easily be downsized.

Arm 23 which is bent in the direction of the arrow and has a predetermined thickness in the depth direction of the opening 20, and integrally engages with the surface of the arm 23 on the opening entrance side (front side) to form the arm 23. It comprises a substantially triangular reinforcing plate 24 which is reinforced and forms a surface substantially identical to the surface of the main body 19 and continues. Therefore, the arm 23 also protrudes from the back surface of the reinforcing plate 24.

As described above, the arm 2 is provided by using the reinforcing plate 24.
When the arm 3 is reinforced, the arm 23 can withstand an external force even if it is elongated and thin. The claw insertion member 11 is locked to the base 10 by locking the door claw with the base 10 by forming two projections 25 (25a, 25b) for retaining and sliding on the outer surface parallel to the moving direction of the main body 19. To be movable in the direction in which the door is to be locked and the direction in which the door claw is unlocked (retracted). It should be noted that the opening 20 is closed so that the inside of the opening 20 is deep enough for a nail to enter.

The lock mechanism 12 includes an operation member 26, a heart cam 27 installed therein, a lock pin 28 fitted in a heart groove described later, and a compression coil for urging the operation member 26 in the direction of the claw insertion member 11. It comprises a spring 29 and a solenoid 30 for moving the operating member 26 in the direction opposite to the direction of the claw insertion member 11. As shown in FIG. 5, the operating member 26 has a door claw lock engaging portion 22 of the claw insertion member 11 at a corner in the door claw unlocking direction on the claw insertion member installation side of the rectangular plate-shaped main body 31. A square columnar projection 32 is formed toward the front side as a door claw lock engagement portion corresponding to the above.

A trapezoidal tubular switch operating projection 33 is similarly formed facing the front side at the center of the main body 31 near the long side on the side where the locking projection 32 is formed. The connecting projection has a receiving hole 35 that protrudes laterally from a corner on the diagonal to the corner where the locking projection 32 is formed, and that is fitted with the tip of the plunger 34 of the solenoid 30 toward the back. The part 36 is formed. Also, the main body 31
From the vicinity of the short side on the side where the connecting projection 36 is formed to the back side, a projection (not shown) formed with a receiving point for receiving one end of the compression coil spring 29 and the like are formed as the connecting projection 36. It is formed continuously. In addition, a columnar projection (indicated by a dotted line) 37 serving as a rotation axis of the heart cam 27 is formed in the center of the main body 31 near the other long side, facing the back side.

The heart cam 27 has a hexagonal plate having a rectangular projection formed in one corner portion toward the side, and a shaft hole formed in the vicinity of the projection. A heart groove 38 is formed in the center of the back surface. As shown in FIG. 6, the heart groove 38 is a groove in which the back surface is recessed in a heart shape, and a heart-shaped projection 39 is provided at the center thereof. Then, as shown in FIG. 7, the depth of the heart groove 38 is the deepest in the peripheral region and the portion near the peripheral region.
Shallow gradually toward the surrounding area, and shallowest near the peripheral area. Also, the depth gradually increases toward the peripheral region, and gradually decreases from the portion closer to the peripheral region toward the peripheral region.
With respect to the operation member 26 which normally moves in the direction of the arrow, the position of the heart cam 27 is restricted from being manually rotated by a manual release member described later, and a heart groove 38 is arranged as shown in FIG. The claw insertion member 11 is provided in the left direction of the arrow, and the solenoid 30 is provided in the right direction.

The lock pin 28 has a crank shape.
The rear end is rotatably fitted into a through hole provided in the bottom plate 17 of the base 10, and the rear end is pressed against the bottom plate 17 of the base 10 using a contact piece 40 having a spring force. Push. Then, the tip of the lock pin 28 contacts the inner surface of the heart groove 38, and the tip cannot move in the moving direction of the operating member 26, but moves in a direction perpendicular to the moving direction or in the depth direction of the heart groove 38. Can be supported as possible. The other end of the compression coil spring 29 is received by a projection 41 formed on the bottom plate 17 of the base 10.

Also, the solenoid 30 is provided with the heart cam 27 on the operating member 26 and uses the lock pin 28, the compression coil spring 29, etc., so that only one is required, and the device 9 can be downsized. And plunger 3
A metal ring 42 is fixed to the end of the metal ring 4 as a positioning means for setting a suction distance at a position close to the tip thereof.
3 is set up. Then, when the plunger 34 is sucked, the metal ring 42 is directly connected to the fixed core 4 of the solenoid body.
The operating noise generated when the button 4 is hit can be eliminated by the rubber ring 43 and can be reduced so as not to cause any trouble.
Note that 45 is a coil and 46 (46a, 46b) are terminals, but the terminals 46 are exposed to the outside.

Further, a micro switch is used for the lock detector 13. Then, with the movement of the operation member 26, the push button 47 is pressed or released by the operation projection 33 provided on the operation member 26, so that it can be detected that the operation member 26 is at the lock position. . Note that the terminal 48 of the microswitch 13 is also exposed to the outside.

The switch section 14 includes a seesaw cam 49 having a rotating shaft, a fixed contact 50 for opening and closing a circuit, and a movable contact 51. The fixed contact 50 is provided on one fixed terminal, and the movable contact 51 is provided on the other. And a circuit portion provided at the distal end of the movable piece 52 having a spring force and having the base end fixed to the fixed terminal. One end of the seesaw cam 49 is interposed between the claw insertion member 11 and the compression coil spring 53 for urging the claw insertion member 11 in the door claw unlocking direction, and the other end is connected to the movable piece 52. Make contact.

Then, the urging force of the compression coil spring 53 always acts on one end of the seesaw cam 49. Therefore, a rotational force in the right direction is applied to the seesaw cam 49, and the force for pushing the movable piece 52 is weakened.
51 is in a normally open state. At this time, the biasing force of the movable piece 52 is also applied to the other end of the seesaw cam 49, so that the seesaw cam 49 tends to rotate further rightward. When such a switch unit 14 is provided, a large current switch different from the lock detection micro switch 13, for example, a switch for a 15 A motor and a heater can be used, and its ON and OFF can be linked with the opening and closing operation of the door. It is safe because it can. The terminals 54 (54a, 54b) of the large current switch are also exposed to the outside.

The manual release mechanism 15 includes a manual release member 5.
5 and a compression coil spring 56 for urging the manual release member 55 in the direction of the solenoid 30. The manual release member 55 is formed in an elongated box shape having a partially closed front side and an open back side, and a position regulating protrusion 57 of the heart cam 27 is provided at the center of the front side of the side wall on which the operation member 26 is installed. A manual release projection 58 is provided from the side wall on the side where the seesaw type cam 4 is installed, to the outside through a through hole formed in the bottom plate 17 of the base 10 to the outside. or,
The compression coil spring 56 is housed inside the manual release member 55, one end of which is in contact with a receiving projection (not shown) projecting from the bottom plate 17 of the base 10, and the other end is the inner surface of the side wall on the side of the solenoid 30. Abut.

Then, at normal times, the manual release member 55 is provided on the operating member 26 for connection with the plunger 34.
6 and can be positioned. At this time, the central projection 57 of the manual release member 55 restricts the position of the heart cam 27 so that it cannot rotate. It should be noted that a string for manual release (not shown) is connected to the tip of the manual release projection 58 that comes out of the manual release member 55.

Then, after housing a number of members constituting the device 9 in predetermined positions of the base 10, respectively, the case 1
The door lock device 9 is completed by screwing the cover 6 on. At the edge of the opening portion 59 of the case 16 into which the nail is inserted, a projection 60 (60a, 60b) with a slope is provided at a position opposite to the edge to guide the insertion of the nail.

When the door lock device 9 is installed at a predetermined position of the main body of the washing machine and the door is opened so that the laundry can be put into the drum, the members and the like can be seen in FIG.
It is in the initial state as shown in FIG. At that time, the claw insertion member 11
The lock projection 32 of the operation member 26 is fitted in the inner space of the arm 23 provided at the first position. Therefore, when the door is closed, the claw provided on the door enters the opening 20 of the claw insertion member 11 through the opening 59 of the case 16.

Then, as soon as the pawl enters, the pawl is pushed by the door pawl, and the pawl insertion member 11 moves in the direction to lock the door pawl against the urging force of the compression coil spring 53 as shown in FIG. Then, the arm 23 is separated from the locking projection 32 of the operation member 26, and is pushed by the switch operation projection 21 of the claw insertion member 11, whereby one end of the seesaw cam 49 rotates leftward. Therefore, the other end of the seesaw cam 49 pushes the movable piece 52 against the spring force, and the two contact points 50,
The high current switch can be turned on by closing 51. The moving distance (stroke) of the claw insertion member 11 and the two contact points 5
The relationship between 0 and 51 and the contact pressure is as shown by the line A in FIG. Therefore, even if the stroke of the claw insertion member 11 is increased and the lock of the door claw is strengthened, the contact pressure can be maintained at a suitable constant pressure, and the abrasion of the contacts 50 and 51 can be reduced. In the case where the movable piece 52 is directly pushed by the claw insertion member 11, it becomes like the B line.

When it is necessary to add laundry after the door is closed in this way, if the user pulls the door and tries to pull out the claws from the openings 20, 59, the door claws are still locked. Therefore, the position of the tip of the arm 23 and the position of the locking projection 32 are shifted. Therefore, the arm 23 and the locking projection 32 do not hinder the movement,
With the urging force of the compression coil spring 53 acting on the claw insertion member 11, the claw insertion member 11 can be freely moved in the door claw lock release direction to pull out the claw. However, if the start button is pressed after the door is closed and the claw insertion member 11 is moved in the door claw locking direction, current flows through the solenoid 30 and the plunger 34 is sucked. Then, the operation member 26 moves against the urging force of the compression coil spring 29, and the locking projection 32 of the operation member 26
At the front side in the door claw unlocking direction.

At this time, as the operation member 26 moves, the tip of the lock pin 28 moves inside the heart groove 38 from a relatively position, and then moves. Therefore, when the tip of the lock pin 28 comes to the position of the concave portion of the heart-shaped projection 39 (the position indicated by the dotted line in FIG. 6), the power supply to the solenoid 30 is stopped. Then, since the lock pin 28 locks the heart cam 27 and the operation member 26, the position can be maintained even when the force of the compression coil spring 29 is acting. Therefore, the claw insertion member 11 cannot move in the door claw unlocking direction, and the door is locked.

When the operating member 26 is moved in the locking direction, the protrusion 33 provided on the operating member 26 presses the push button 47 of the microswitch 13. Then, the lock state is detected by the micro switch 13, and water supply or the like can be started into the drum. After such water supply, washing, dehydration, drying, etc. are performed, but even if a power failure occurs in the middle, the door is locked regardless of power supply,
Of course, the door does not open and the tank water does not flow out.

When the solenoid 30 is energized after the drying is completed, and the plunger 34 is further sucked, the operating member 26 moves against the urging force of the compression coil spring 29. Then, the movement of the lock pin 28 is started after the tip of the lock pin 28 comes out of the recess of the heart-shaped projection 39. Then, when the power supply to the solenoid 30 is stopped, the urging force of the compression coil spring 29 acts on the operation member 11 and the lock pin 2
The tip of 8 moves and returns to the position. Therefore, the relationship between the arm 23 of the claw insertion member 11 and the locking projection 32 of the operation member 26 returns to the position shown in FIG. 9, and the door can be released. The door can be opened after dehydration by pressing the pause button.

However, if a power failure occurs during such washing, dehydration, drying, etc., the door will naturally stop in the locked state. Therefore, when it is desired to take out the laundry, the string is pulled, and the manual release member 55 is moved against the urging force of the compression coil spring 56. Then, as shown in FIG. 12, the position regulating member 57 of the manual release member 55 is
And the heart cam 27 rotates. This is because a spring force is applied to the heart cam 27 so as to always rotate from the lock pin 28 and return to the initial position. Therefore, the lock pin 28 rotates the heart cam 27 and returns the operation member 26 to the original position. Thus, the door can be released.

[0033]

According to the present invention described above, claim 1
In the invention described in the above, since the moving direction of the operating member provided in the lock mechanism is perpendicular to the moving direction of the claw insertion member, a large load is applied to the lock mechanism even if the door is opened when the door claw is locked. Instead, the mechanical strength of the lock mechanism can be reduced, and the lock mechanism can be made compact. In addition, since the solenoid is used as a drive source of the operation member, the operation member can be quickly moved to lock the door claw and unlock the door claw, thereby speeding up the operation of the device.

Also, a heart cam is rotatably provided on the operating member, and the tip of the lock pin is brought into contact with the heart groove, and the moving direction of the tip of the lock pin cannot be moved in the moving direction of the operating member. The compression coil spring and solenoid are used as operating member moving means to support the position of the heart cam so that it can move in the direction perpendicular to the direction and the depth direction of the heart groove, and to regulate the position of the heart cam so that it can not be rotated normally by the manual release member. You only have to provide one for each. Also, even if a power failure occurs when the door claw is locked, the door does not open and the tank water does not flow out. However, the door can be opened by moving the manual release member and rotating the heart cam during a power failure. In addition, the device can be downsized by reducing the mechanical strength of the lock mechanism unit and downsizing it and by using a single solenoid.

According to the second aspect of the present invention, the inner space of the arm provided on the operation part installation side of the claw insertion member can be a space for accommodating the locking projection provided on the claw insertion member installation side of the operation member. Since the position of the tip of the arm and the position of the locking projection are shifted before the lock mechanism is activated, the arm and the locking projection do not hinder the movement of the claw insertion member, and the door can be freely opened and closed. it can. However, after the lock mechanism is actuated, the locking projection comes to the front of the claw insertion member in the door claw unlocking direction and is aligned with the tip of the arm, so that the claw insertion member can be easily locked without returning. When the operation member is returned to the original position, the lock can be easily released. Moreover,
Since the arm is reinforced using the reinforcing plate, the arm can withstand external force even if the arm is formed to be elongated and thin.

According to the third aspect of the present invention, since the muffling member is placed on the solenoid body side of the positioning means fixed to the plunger, the positioning means directly contacts the fixed iron core of the solenoid body when the plunger is sucked. Can be easily eliminated by the muffling member.

In the invention according to claim 4, one end of the seesaw cam is interposed between the claw insertion member and the compression coil spring, and the other end of the seesaw cam is provided with a movable contact corresponding to a fixed contact. Since the switch unit is provided in contact with the movable piece having the spring force, even if the stroke of the claw insertion member is increased and the lock of the door claw is strengthened, the contact pressure is maintained at a favorable constant pressure, Wear due to contact of the contact can be reduced. Also, the switch section is a large current switch, and the on / off of the switch can be linked with the opening and closing operation of the door, which is safe.
