う。By the way, in order to judge whether or not the clutch is completely switched during the transition from the washing stroke or rinsing stroke to the dehydration stroke, the moments of inertia of rotation of the rotary blade 4 and the washing / dehydrating tub 3 are utilized. There is. That is, when the clutch is engaged for shifting to the dehydration step, first, the plunger 17 is lowered to energize the motor 5 for a short time, and then the clutch pin 18 and the hole 13 provided in the clutch piece 12 are engaged with each other. After that, the position of the clutch is detected.

換えができない場合があった。When shifting from the washing process to the dewatering process, the dewatering shaft 16 is not yet joined to the washing shaft 11 and the washing / dehydrating tub 3 is in a free state. In this state, when the amount of laundry in the washing / dehydrating tub 3 is large, wet laundry containing water before dehydration is placed on the rotor 4 after washing and rinsing are completed and drained. When it is placed, this laundry becomes a load and the rotor 4 and the washing / dehydrating tank 3
And move together. As a result, the clutch pin 18
There was a case where the clutch piece 12 could not be switched because the clutch piece 12 did not shift.

う。If the clutch cannot be switched, the laundry will act as a clutch at the time of detecting the subsequent switching, and the clutch pin 18 and the hole 13 provided in the clutch piece 12 will actually be formed. Even if they are not meshed, that is, even though the clutch is still on the washing side, the washing and dehydrating tub 3 has a larger moment of inertia than the rotary blades 4, so the clutch meshes and becomes the dehydrating side. It is judged to be a thing and it shifts to the dehydration process.

するおそれがある。In this state, when the laundry moves to the dehydration process and the centrifugal force causes the laundry to move from the top of the rotary blades 4 to the side of the peripheral wall of the washing / dehydrating tub 3, the laundry is washed / dehydrating the tub 3.
At the moment of moving to the peripheral wall side, the washing / dehydrating tub 3 in the free state tries to stop, while the rotary blades 4 continue to rotate, so that the clutch pin 18 and the hole 13 provided in the clutch piece 12 are Are engaged and the clutch is engaged. At this time, a sound may be generated due to an impact, or the clutch may be damaged.

ある。The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, and to change the clutch when switching from the washing process to the dehydration process or from the dehydration process to the cleaning process, the laundry is washed and dehydrated. Even if it is in the tub, it prevents the load from switching the clutch and ensures switching between the clutch pin and the hole provided in the clutch piece, preventing the laundry from acting as a clutch and engaging the clutch. An object of the present invention is to provide a clutch control method for a one-tub type washing machine that can prevent the impact noise and the occurrence of damage to the clutch portion due to.
