Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) As shown in FIG. 4, an upper housing 2 is provided on an upper portion of a lower housing 1 so as to cover the lower housing 1, and an opening provided for the laundry provided in the upper housing 2 is provided. The lid 3 is attached so as to be openable and closable around the rear portion of the upper housing 2 so as to close the portion. A front housing 4 including an operation panel for performing a switch operation or the like is provided in front of the upper housing 2, and covers an upper front of the lower housing 1. The lower housing 1, the upper housing 2, and the front housing 4 form a housing that forms the outer shell of the laundry device.

The lid lock device 5 locks the lid 3 in a closed state, and is provided on the front housing 4. As shown in FIG. 5, the lid lock lever 6 is protruded and retracted from the lid lock device 5 through a hole in the front case 4, and the hole 3 a provided in front of the lid 3 is penetrated with the lid lock lever 6 protruding. . In this state, even if an attempt is made to lift the lid 3 upward to open it, the lid lock lever 6 is locked because it is hooked on the hole 3a of the lid. In this embodiment, the lid lock device 5 is provided on the front housing 4, but may be provided on either the lower housing 1 or the upper housing 2.

The lid lock device 5 is configured as shown in FIG. The base 7 forms an outer shell of the lid lock device 5,
It fixes each built-in component. The solenoid 8 has a yoke 8b that forms a magnetic path, and has a winding resin-molded, and supplies power from a terminal 8a. The plunger 9 is formed of stainless steel or the like, and is disposed so as to be able to reciprocate inside the hollow of the winding of the solenoid 8. When the plunger 9 is connected to the operation plate 10 at the connection portion 10a and the plunger 9 is sucked by energizing the solenoid 8, the operation plate 1 is
0 is simultaneously operated.

The rotating plate 11 is provided with a projection 1 provided on the operation plate 10.
0b, and is rotatable around the fulcrum 12 formed by the protrusion in accordance with the operation of the operation plate 10. The operation plate 10 is connected to the short arm 11a of the rotating plate 11 by a projection 10b, and the lid lock lever 6 is connected to the long arm 11b by a projection 6a provided on the lid lock lever 6. This rotating plate 1
1 rotates like a seesaw around a fulcrum 12 to transmit the operation of the operation plate 10 to the lid lock lever 6.

The return spring 13 includes a projection 7a provided on the inner wall of the base 7 and a projection 6b provided integrally with the lid lock lever 6.
, And urges the lid lock lever 6 in the direction of pushing back into the base 7, that is, in the direction of unlocking. Thus, when the solenoid 8 is no longer energized, the lid lock lever 6 is pushed back into the base 7.

On the other hand, when the solenoid 8 sucks the plunger 9, the force required to repel the return spring 13 and the operation plate 10, the rotating plate 11 and the lid lock lever 6 are applied to the base 7.
It becomes the combined force of the frictional forces when sliding inside. At this time, the force repelling the return spring 13 is obtained by multiplying the repulsive force of the return spring 13 itself by the ratio of the length from the fulcrum 12 to the protrusion 10b and the length from the fulcrum protrusion 12 to the protrusion 6a.

The operation plate 10 and the rotating plate 11 are made of a polyamide resin, a polyacetal resin or the like to improve sliding. The lid lock lever 6 is formed of a polyacetal resin or the like because it also requires a shearing force to resist a force for forcibly opening the lid 3 at the time of locking.

As shown in FIGS. 2 and 3, a substantially double Y-shaped groove 14 is provided on the bottom side of the operation plate 10, and a leaf spring 15 is provided.
The pin 16 urged in the step 1 moves the groove 1 according to the movement of the operation plate 10.
4, the plate spring 15 and the pin 16 are engaged with the lower case 7a constituting the base 7 at the hole 7c and the recess 7d, respectively. In particular, the hole 7c is formed in a mortar shape so that the pin 16 can move almost freely.

The groove 14, the leaf spring 15, and the pin 16 constitute a self-holding portion for holding the state of the lid lock lever 6, and the pin 16 is relatively moved in the direction of the arrow in FIG. In the state where the solenoid 8 is not energized,
The state of the operation plate 10 is maintained so as to be located at 4a or 14c, and the state of the lid lock lever 6 is maintained.

The switch 17 detects the state of the lid lock lever 6 and is formed of a conductive leaf spring. One side 17a of the switch 17 is formed integrally with the operation plate 10.
Opening and closing operations are performed by pressing with c, a conductive leaf spring is supported by a support 18 made of resin or the like, and an electric signal is taken out from the terminal 17b.

On the other hand, a release lever 10d penetrating through the opening 7e of the upper case 7b is formed integrally with the operation plate 10, and the release plate 10d is manually operated from the outside to move the operation plate 10. Then, the same operation as when the operation plate 10 is driven by the solenoid 8 is provided.

The operation of the above configuration will be described. When it is necessary to put laundry or the like into the housing, close the opening with the lid 3 and start the operation, and lock the lid 3 in a closed state such as a dehydration step or a drying step, a lid locking device 5 is operated, the lid lock lever 6 is protruded from the lid lock device 5 through the hole of the front housing 4, and penetrates the hole 3 a provided in front of the lid 3 to lock the lid 3.

The operation of the lid lock device 5 at this time will be described. When power is supplied from the terminal 8a of the solenoid 8, the plunger 9 is sucked, and at the same time, the operation plate 10 connected to the plunger 9 moves in the direction of arrow a in FIG. As a result, the rotating plate 11 rotates counterclockwise about the fulcrum 12 and transmits the operation of the operation plate 10 to the lid lock lever 6. As a result, the lid lock lever 6 is
Is driven in the direction of the arrow b against the spring force, and protrudes from the base 7 to lock the lid 3.

At this time, since the length from the fulcrum 12 to the protrusion 6a is longer than the length from the fulcrum 12 to the protrusion 10b,
A stroke obtained by multiplying the length ratio by the stroke of the plunger 9 is obtained by the lid lock lever 6. Thus, the stroke of the plunger 9 may be smaller than the stroke of the lid lock lever 6, and the size of the solenoid 8 can be reduced, and the overall size of the lid lock device 5 can be reduced.

At this time, the groove 14, the leaf spring 15, and the pin 16
The operation of the self-holding unit constituted as described above will be described with reference to FIG. When the lid lock lever 6 is retracted and returned (the state before the solenoid 8 is energized), the return spring 13
Urges the lid lock lever 6 in the unlocking direction, so that the pin 16 is located at 14a. When the solenoid 8 is energized and the plunger 9 is sucked, the operation plate 1
0 moves at the same time, and the pin 16 relatively moves to 14b.

Here, when the energization of the solenoid 8 is stopped, the pin 16 moves relative to 14c in response to the return of the operation plate 10 by the spring force of the return spring 13, and is mechanically held here. In this state, the lid lock lever 6 remains in the protruding state, and the lid 3 is locked without energizing the solenoid 8.

At this time, the switch 17 is turned on by pushing one side 17a by the projection 10c formed integrally with the operation plate 10, and the ON signal is taken out from the terminal 17b. It is possible to detect that the cover 3 is locked in the protruding state. By inputting this ON signal to a control circuit (not shown) constituted by a microcomputer or the like, the state of the lid lock can be determined, so that controllability can be improved.

Next, from this state, the solenoid 8
When the power is supplied to the control panel 10, the operation plate 10 also moves at the same time,
Moves relatively to 14d in FIG. 3, and when the energization of the solenoid 8 is stopped, the pin 16 relatively returns to 14a in response to the return of the operation plate 10 by the spring force of the return spring 13. This is a state where the lid lock lever 6 is retracted to the initial state and returned, and the lock of the lid 3 is released,
The lid 3 can be opened manually.

At this time, the switch 17 is turned off because the operation plate 10 returns to the initial state, and an off signal is taken out from the terminal 17b. 3 can be detected as being unlocked.

As described above, the groove 14, the leaf spring 15, and the pin 16
The lid lock lever 6 can be held in the locked state and the returned state without the need to continuously energize the solenoid 8 by the action of the self-holding portion constituted by the above. For this reason, the solenoid 8 can be operated with a short-time energization, and a rise in temperature is suppressed, so that the solenoid 8 can be downsized, and thus the entire lid lock device 5 can be downsized.
Further, since the switch 17 is formed of a conductive leaf spring, the cost can be reduced.

Further, for example, when a power failure occurs with the lid 3 locked, the lock can be released by manually operating the release lever 10d from the outside, so that operability and serviceability can be improved.

In this embodiment, the switch 17 is opened and closed by the projection 10c formed integrally with the operation plate 10. However, the switch 17 is opened and closed by the rotary plate 11 and the lid lock lever 6. The same effect can be obtained.

In this embodiment, the release lever 10d
Is provided integrally with the operation plate 10, but the same effect can be obtained by providing the same integrally with the rotating plate 11 and the lid lock lever 6.

(Embodiment 2) As shown in FIG. 6, the micro switch 19 detects the state of the lid lock lever 6, and is provided with a lever 19a for pressing a button. The lever 19a is configured to be pressed according to the operation of the operation plate 10 via a buffer spring 20 engaged with a projection 10e formed integrally with the operation plate 10.

The buffer spring 20 is provided to absorb the operation amount of the operation plate 10 with respect to the required stroke for turning on the micro switch 19, and is provided to absorb the movement amount. This is not necessary if is satisfied within an acceptable range. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described. In addition,
The operation at the time of locking or unlocking the lid 3 that closes the opening of the housing is the same as the operation of the first embodiment, and a description thereof will be omitted.

After the solenoid 8 is energized, when the energization is stopped and the lid 3 is locked, the microswitch 19 is pushed through the buffer spring 20 and the lever 19a to turn on, and an ON signal is taken out. Thus, it is possible to detect from the ON signal that the lid 3 is locked with the lid lock lever 6 protruding. By inputting this ON signal to a control circuit (not shown) constituted by a microcomputer or the like, the state of the lid lock can be determined, so that controllability can be improved.

Next, from this state, the solenoid 8
When the lid lock lever 6 is retracted to the initial state to return to the initial state and the lid 3 is unlocked, the micro switch 19 is turned off because the operation plate 10 returns to the initial state. Then, by extracting the OFF signal, it is possible to detect from the OFF signal that the lid 3 is unlocked with the lid lock lever 6 returned.

Thus, the position of the operation plate 10, that is, the position of the lid lock lever 6, can be detected, so that it is possible to detect whether the lid lock lever 6 has popped out of the lid lock device 5 or has returned. By inputting this detection signal to a control circuit (not shown) constituted by a microcomputer or the like, the state of the lid lock can be determined, so that controllability can be improved. In addition, by using the microswitch 19, waterproofness can be improved.

In this embodiment, the microswitch 1
Reference numeral 9 denotes an opening / closing operation performed by a projection 10e formed integrally with the operation plate 10. However, the opening / closing operation may be performed by the rotating plate 11 or the lid lock lever 6, and the same effect can be obtained.

(Embodiment 3) As shown in FIG. 7, the permanent magnet 21 is held in a concave portion 10f formed integrally with the operation plate 10, and a reed switch 23 built in the concave portion of the opposing holder 22 has a magnetic force. It is operated with. The permanent magnet 21 moves integrally with the operation plate 10, and the reed switch 23
, The reed switch 23 is turned on and the operation plate 10 is turned on.
, And thus the position of the lid lock lever 6 can be detected.

The filling resin 24 fixes the reed switch 23 and protects the reed switch 23 from electric leakage between the terminals. The conducting wire 25 connects the connector 26 connected to the outside of the lid lock device 5 to the terminal of the reed switch 23. Is what you do. Other configurations and basic operations are the same as those of the first or second embodiment.

With this configuration, the state detecting section for detecting the state of the lid lock lever 6 can be protected from detergent liquid or water droplets to prevent erroneous detection.

In this embodiment, the permanent magnet 21 is held in the concave portion 10f formed integrally with the operation plate 10.
The same effect can be obtained even if the reed switch 23 is appropriately arranged while being held on the rotating plate 11 or the lid lock lever 6.

(Embodiment 4) As shown in FIG. 8, the solenoid 27 has a drive winding 27b and a detection winding 27c, which are electrically independent of each other. The plunger 9 is sucked. At this time, if the plunger 9 approaches or is included in the detection winding 27c, the inductance of the detection winding 27c increases. When this change is taken out from the terminal 27d and used for, for example, a part of a resonance circuit of an externally provided transmitting circuit, the position of the plunger 9 is detected as a change in the transmitting frequency. Other configurations and basic operations are the same as those in the first to third embodiments.

Thus, it is possible to detect whether the lid lock lever 6 is protruding and the lid 3 is locked or opened in the return state. Further, the state of the lid lock lever 6 is changed to the resin molded solenoid 2.
Since the detection can be performed by the detection coil 27c built in the case 7, even if water or detergent liquid enters the case 7, the state can be surely grasped by a control device (not shown) without erroneous detection. .

(Embodiment 5) As shown in FIG. 9, the front case 4 has a hole 4b coaxial with the hole 4a and the hole 3a of the lid 3,
The lid lock lever 6 is configured to penetrate the hole 4a of the front case 4, the hole 3a of the cover 3, and the hole 4b of the front case 4. Other configurations are the same as those in the first embodiment.

In the above configuration, when the lid 3 is locked, if the lid 3 is forcibly opened, the lock lever 6 is locked by the holes 4a and 4b of the front case, so that the lid 3 is not opened. . The lock lever 6 forms a short distance double-ended beam with the hole 4a and the hole 4b of the front case, and can improve the mechanical strength against a force for forcibly opening the lid 3. . Conversely, the material of the lock lever 6 can be made of a relatively inexpensive polyamide resin.
