Inside the outer frame 101, a water tank 104 formed in a bottomed cylindrical shape is elastically supported by a suspension 105. Inside the water tank 104, the washing / dehydrating tank 106 is rotatably held. A large number of dehydration holes 109 are formed on the side wall of the washing / dehydrating tub 106, and the washing water is allowed to pass inside and outside the washing / dehydrating tub 106.

The motor 130 and the transmission mechanism 140 are fixed to the holding portion 120, and the belt 131 is configured to transmit the rotation of the motor 130 to the transmission mechanism 140. The configuration of the transmission mechanism 140 will be described later. The washing shaft 141, which is a part of the transmission mechanism 140, is connected to the stirring blade 107, and the dehydration shaft 142 is connected to the washing / dehydrating tub 106.

A drainage path 111 that communicates the outside of the outer frame 101 with the water tank 104 is connected to the outer bottom of the water tank 104. The drainage path 111 is provided with a drainage valve 112 inside, and the washing water in the water tank 104 is drained to the outside of the washing machine 100 with the drainage valve 112 open.

[1-1-2. Transmission mechanism configuration]
As shown in FIG. 2, in the transmission mechanism 140, the washing shaft 141 that rotates the stirring blade 107 and the dehydration shaft 142 that rotates the washing / dehydrating tub 106 rotate at the same time during dehydration, and the switching clutch 143 operates during washing. As a result, only the washing shaft 141 rotates via the reduction gear 144.

The brake wheel 145 encloses the reduction gear 144, and concentrically prevents the washing / dehydrating tub 106 from rotating together in the dehydration rotation direction during washing, and brakes the rotation of the washing / dehydrating tub 106 at the end of dehydration. A brake band 146 is arranged, a dehydration shaft 142 is fitted above the brake wheel 145, and a gear case 147 is fitted below. The dehydration shaft 142, the brake wheel 145, and the gear case 147 form a dehydration shaft unit.

The dehydration shaft 142 includes the washing shaft 141, and the washing shaft 141 is rotatably supported by the washing shaft 142 by the washing shaft sliding metal 141a.

The gear case 147 includes a gear shaft 149, and the gear shaft 149 is rotatably supported by the gear shaft 149 by the gear shaft sliding metal 149a.

The switching clutch 143 includes a clutch spring 143a, and the upper end of the clutch spring 143a is fitted to the gear case 147 with a tightening allowance, the body is fitted to the gear case 147 and the bushing 148 with a tightening allowance, and the lower end is fitted with the switching clutch 143. I am engaged in.

The brake wheel 145 includes an upper cover 160 into which the upper bearing 161 in which the dehydration shaft 142 is externally encapsulated and fitted, and a bearing case 162 in which the lower bearing 163 in which the gear case 147 is externally fitted and fitted is inserted. Is supported by.

A one-way clutch 164 is provided above the lower bearing 163 to control the gear case 147 to rotate in only one direction (details will be described later).

The clutch lever 150 is rotatably arranged around a clutch lever shaft 151 provided in the bearing case 162, and a clutch claw 152 that engages with the switching clutch 143 is provided at the tip end portion. The clutch lever shaft 151 is concentrically provided with a clutch lever spring 153 that engages the clutch claw 152 of the clutch lever 150 with the switching clutch 143.

As shown in FIGS. 2 and 3, the brake lever 154 causes the brake band 146 to be brought into close contact with or open to the brake wheel 145, and is rotatably arranged around the brake lever shaft 155 provided on the bearing case 162. ing. The brake lever shaft 155 is concentrically provided with brake lever springs 156 so that the brake band 146 is brought into close contact with the brake wheel 145. The brake pin 157 connects the end of the brake band 146 with the brake lever 154. The clutch lever 150 is provided with a bolt 158 so that the tip of the clutch lever 150 comes into contact with the brake lever 154, and a tongue portion 150a is provided at a position close to the brake lever shaft 155 during washing and braking.

As shown in FIGS. 3 and 4, the tip portion of the tongue portion 150a has a shape in which the bolt 158 is in contact with the brake lever 154 and is in contact with the brake lever shaft 155. Further, by tightening the bolt 158 and pushing the brake lever 154, a gap T formed between the tip portion of the tongue portion 150a and the brake lever shaft 155 is secured, and in that state, the bolt 158 is inserted with the nut 159. , It is fixed to the clutch lever 150.

As shown in FIG. 7, when the gap T = 0, the load applied to the brake band 146 is only the load of the brake lever spring 156, but when the gap T> 0, the load is applied to the brake band 146. Since the load of the brake lever spring 156 and the load of the clutch lever spring 153 are added together, a braking torque of about 1.4 times or more can be secured with respect to the case where the gap T = 0. Here, assuming that the spring constant of the clutch lever spring 153 is K1 and the spring constant of the brake lever spring 156 is K2, the relationship is K1 <K2.

A drain valve 112 for draining the washing water in the water receiving tank 1 is provided on the bottom surface of the water receiving tank 1. As shown in FIGS. 3, 5 and 6, the drain valve 112 has a cock packing 114 having a cock spring 113 that closes the water receiving tank 1 in a watertight manner during washing. Further, the drain valve 112 is connected to the operation lever 116a of the electromagnetic drive device 116 via the cock rod 115, and is configured to be opened and closed by the traction operation of the electromagnetic drive device 116.

The cock rod 115 is provided with a brake lever operating portion 115a, and during washing and braking, the brake lever operating portion 115a forms a gap R between the cock rod 115 and the brake lever 154 to form a gap R between the load of the brake lever spring 156 and the clutch. The load of the lever spring 153 is added up and applied to the brake band 146 to secure the braking torque.

When the bolt 158 is tightened, the gap R pushes the brake lever 154 in the direction of the arrow b, and finally decreases to the gap R1 when the gap T between the brake lever shaft 155 and the tongue portion 150a is reached. At the time of time and braking, the brake lever operating portion 115a is arranged so as to secure the relationship of R> R1> 0.

Then, during dehydration and drainage, the brake lever operating portion 115a abuts on the brake lever 154 due to the operation of the electromagnetic drive device 116, R = 0, and the brake lever operating portion 115a further moves in the arrow c direction ( By moving to (see FIG. 6), the brake lever 154 also moves in the direction of arrow c, and at the same time, the brake lever 154 pushes the bolt 158 to finally move the clutch lever 150 to which the bolt 158 is fixed. It becomes.

As a result, the opening and closing of the drain valve 112 and the operations of the brake lever 154 and the clutch lever 150 are linked. At this time, the load of the clutch lever spring 153 is transmitted to the brake lever 154 via the bolt 158 that comes into contact with the brake lever spring 153, and the combined load with the load of the brake lever spring 156 is used as the maximum operating force of the brake lever 154. It will hang on 115a.

Here, assuming that the guaranteed traction force of the electromagnetic drive device 116 is F1, the maximum operating force of the brake lever 154 is F2, and the maximum closing force of the cock spring 113 is F3, the relationship is F1> F2 + F3.

[1-2. motion]
The operation of the washing machine 100 configured as described above will be described below.

At the time of washing, as shown in FIG. 3, the electromagnetic drive device 116 is in the off state, the cock packing 114 closes the drain valve 112 watertightly by the spring force of the cock spring 113 of the drain valve 112, and the brake lever 154 is set. A gap R is formed between the brake lever operating portion 115a, and the clutch lever 150 has a gap T between the tongue portion 150a and the brake lever shaft 155 in a state where the bolt 158 abuts and pushes against the brake lever 154. Is maintained.

Further, the clutch claw 152 of the clutch lever 150 engages with the switching clutch 143 by the clutch lever spring 153, and the clutch spring 143a is released from the bushing 148, so that the rotation of the motor 130 is transmitted via the bushing 148 to the gear shaft. It is transmitted to 149, the reduction gear 144, the washing shaft 141, and the stirring blade 107.

At this time, the brake band 146 is brought into close contact with the brake wheel 145 by adding the load of the brake lever spring 156 and the load of the clutch lever spring 153, and the washing and dehydration tub 106 rotates together with the rotation of the clothes in the dehydration rotation direction. To prevent. At the same time, the one-way clutch 164 arranged above the lower bearing 163 prevents the washing and dehydration tub 106 from rotating together due to the rotation of clothes in the reverse rotation direction of dehydration, and the clutch spring 143a rotates together. It is possible to prevent the bushing 148 and the gear case 147 from being connected to each other and becoming dehydrated due to the change of the open state to the close contact state and the locking operation of the motor 130 due to the overload.

At the time of dehydration, as shown in FIG. 6, the electromagnetic drive device 116 is turned on, the cock rod 115 is pulled and moved in the direction of arrow c, the drain valve 112 is opened, and the brake lever operating portion 115a provided on the cock rod 115 a. However, when it comes into contact with the brake lever 154, the brake lever 154 rotates about the brake lever shaft 155 in the arrow d direction against the total load of the brake lever spring 156 and the clutch lever spring 153.

Along with this, when the bolt 158 is pushed by the brake lever 154, the clutch lever 150 moves in the direction of the arrow e around the clutch lever shaft 151 against the load of the clutch lever spring 153. As a result, the clutch claw 152 of the clutch lever 150 is separated from the switching clutch 143, and the clutch spring 143a is brought into close contact with the bushing 148, whereby the rotation of the motor 130 is transferred to the stirring blade 107 and the washing / dehydrating tank 106. It will be transmitted at the same time.

On the other hand, when the brake lever 154 moves in the direction of the arrow d, the brake band 146 is released from the brake wheel 145 by the brake pin 157 moving in the direction of the arrow f around the brake lever shaft 155, and the brake is released. , The washing / dehydrating tub 106 can be rotated.

When the washing / dehydrating tub 106 is braked, it is in the same state as during washing, the electromagnetic drive device 116 is turned off, the cock rod 115 returns in the direction of arrow b, and the drain valve is as shown in FIGS. 3 and 6. The cock packing 114 watertightly closes the drain valve 112 by the spring force of the cock spring 113 of the 112, and the brake lever 154 moves around the brake lever shaft 155 in the direction opposite to the arrow c direction, and the brake lever operating portion 115a It returns to the state of releasing the contact with.

Further, the clutch lever 150 returns to a state where the gap T between the tongue portion 150a and the brake lever shaft 155 is maintained in a state where the bolt 158 abuts and pushes against the brake lever 154 due to the load of the clutch lever spring 153, and the clutch lever It moves and returns in the direction opposite to the arrow d direction around the axis 151.

The clutch claw 152 of the clutch lever 150 engages with the switching clutch 143 by the load of the clutch lever spring 153, and the clutch spring 143a is released from the bushing 148 to rotate the motor 130 via the bushing 148. It is transmitted to the shaft 149, the reduction gear 144, the washing shaft 141, and the stirring blade 107 so that it can rotate.

At this time, the brake band 146 is brought into close contact with the brake wheel 145 by adding the load of the brake lever spring 156 and the load of the clutch lever spring 153, and brakes the rotation of the washing / dehydrating tank 106.

Here, as shown in FIG. 7, the relationship between the gap T and the braking torque increases by about 1.4 times or more with respect to the gap T = 0, so that the washing / dehydrating tub is used even during dehydration. The braking time until the rotation of the 106 is stopped can be shortened, the user can prevent the user from coming into contact with the rotating body when the clothes are taken out from the washing / dehydrating tub 106, and the safety can be improved. Further, the structure of the electromagnetic drive device 116 can be simplified only by the pulling operation of the brake lever 154, and the power consumption can be reduced by turning off the electromagnetic drive device 116 except during dehydration and drainage.

FIG. 5 shows the relationship between the gap T, the clutch claw 152 of the clutch lever 150, and the engagement S (see FIG. 3) between the outer circumference of the switching clutch 143.

The engagement margin S is optimal when the gap T = 0, and as the gap T becomes larger by tightening the bolt 158, the clutch lever 150 is centered on the clutch lever shaft 151 even when not dehydrated due to the reaction force. Since it moves in the direction of arrow e (see FIG. 6) from the outer circumference of the switching clutch 143, it decreases as shown by the curve W. Then, in the next washing after dehydration, the half-clutch state is reached, and in the worst case, the operation of the stirring blade 107 becomes defective at the next washing.

Therefore, by using a clutch lever 150 having the same dimensions as the gap T formed by tightening the bolt 158 and shortening the tip of the tongue portion 150a, the gap T is formed by tightening the bolt 158, as shown in the curve X. The clutch S can maintain an appropriate state and prevent malfunction during washing. Further, the control circuit and the control sequence can be simplified without changing the parts other than the drive device 34, and the design cost and the parts cost can be reduced.
