[0020]
If the lid detection means 5 detects opening / closing of the lid 3 in step 301, the process returns to step 301 if the process does not proceed to step 302. In step 302, the control means 12 increases the opening / closing count stored in the opening / closing count storage means 10 by one. In step 303, the control means 12 determines whether or not the number of times of opening and closing exceeds 10, and if so, the process proceeds to step 304, and if not, returns to step 301. In step 304, the control means 12 drives the cloth amount detection means 6. In step 305, the cloth amount detection means 6 drives the motor 4 by the cloth amount detection control means 8 for 10 seconds. In step 306, the cloth amount detection control means 8 measures the number of rotations of the washing tub 2 by the rotation sensor 7 for 10 seconds. In step 307, the cloth amount detection control means 8 determines the amount of laundry from the correspondence table between the rotation speed and the cloth amount. In step 308, the control means 12 determines whether or not the amount of laundry determined by the cloth amount detection means 6 exceeds 4 kilograms. If it exceeds, the process proceeds to step 309, otherwise returns to step 301. In step 309, the control means 12 returns the opening / closing count stored in the opening / closing count storage means 10 to zero. In step 310, the control means 12 causes the fully automatic washing machine 1 to start washing.
[0021]
For example, when the correspondence table between the number of rotations and the amount of cloth is FIG. 3 and the number of times of opening and closing stored in the number of times of opening and closing storage 10 is 9, the user opens and closes the lid 3 in the washing tub 2 and puts the laundry. In step 301, the lid detecting means 5 detects opening / closing of the lid 3, and the process proceeds to step 302. In step 302, the control means 12 increases the opening / closing number 9 stored in the opening / closing number storage means 10 by 1 to 10 times. In step 303, the control means 12 determines that the opening / closing frequency does not exceed 10 times, and returns to step 301.
[0022]
Next , when the user opens and closes the lid 3 in the washing tub 2 and puts the laundry, the lid detecting means 5 detects the opening and closing of the lid 3 in step 301 and moves to step 302. In step 302, the control means 12 increases the opening / closing frequency 10 times stored in the opening / closing frequency storage means 10 by 1 to 11 times. In step 303, the control means 12 determines that the number of opening / closing operations exceeds 10 times, and proceeds to step 304. In step 304, the control means 12 drives the cloth amount detection means 6, and in step 305, the cloth amount detection means 6 drives the motor 4 by the cloth amount detection control means 8 for 10 seconds. In step 306, the cloth amount detection control means 8 measures the number of rotations of the washing tub 2 by the rotation sensor 7 for 10 seconds. If the number of rotations is 50 at this time, in step 307, the cloth amount detection control means 8 determines the amount of laundry as 3.5 kilograms from the correspondence table of FIG. In step 308, the control means 12 determines that the amount of laundry determined by the cloth amount detection means 6 does not exceed 4 kilograms, and returns to step 301.
[0023]
Next, when the user opens and closes the lid 3 and puts more laundry, the same processing is performed from step 301 to step 306, and the result of the rotation sensor 7 measuring the rotation speed of the washing tub 2 for 10 seconds in step 306 is the result. If it is 30 times, in step 307, the cloth amount detection control means 8 determines the amount of laundry as 4.5 kilograms from the correspondence table of FIG. In step 308, the control means 12 determines that the amount of laundry exceeds 4 kilograms, and proceeds to step 309. In step 309, the control means 12 returns the open / close count stored in the open / close count storage means 10 to 0, In step 310, the control means 12 causes the fully automatic washing machine 1 to start washing.
[0024]
In this case, the cloth amount detecting means 6 is not driven when the number of times the laundry is put in is 10 times or less, and the cloth amount detecting means 6 is driven and the amount of the laundry is measured when the number of times of putting in is 11 times or more. . When the amount of laundry in the washing tub is 4 kilograms or less, washing is not started, and when the amount of laundry exceeds 4 kilograms, washing is started by the control means 12 even if the user does not specify start.
[0025]
(Embodiment 4)
In FIG. 9, 1, 3 and 5 are the same as those of the fully automatic washing machine in the embodiment of the invention of claim 1. 13 is a reservation time setting means for setting a reservation time for starting washing by input from the user, 14 is a reservation time storage means for storing the washing start time set by the reservation time setting means 13, and 15 is whether the lid is opened or closed. Open / close storage means for storing the time, 16 is a time measuring means for measuring the time, and 17 is an open / close storage means 15 that stores the opening / closing of the lid 3 when the lid detecting means 5 detects the opening / closing of the lid 3, When the time indicated by the means 16 coincides with the reservation time stored in the reservation time storage means 14 and the opening / closing storage means stores the opening / closing of the lid, the opening / closing storage means 15 stores it. This is a control means for erasing the contents and causing the fully automatic washing machine 1 to start washing.
[0026]
About the fully automatic washing machine comprised as mentioned above, the operation | movement is demonstrated using FIG.
[0027]
If there is an input from the user in the reservation time setting means 13 in step 401, the process proceeds to step 402, and if not, the process proceeds to step 403. The reservation time set by the reservation time setting means 13 in step 402 is stored in the reservation time storage means 14, and if the lid detection means 5 detects the opening / closing of the lid 3 in step 403, the process proceeds to step 404. If not, go to Step 405. In step 404, the control means 17 stores in the open / close storage means 15 that the lid 3 has been opened and closed, and the process returns to step 401. If the time indicated by the time measuring means 16 in step 405 matches the reservation time stored in the reservation time storage means 14, the process proceeds to step 406. Otherwise, the process returns to step 401. If it is stored in step 406 that the lid has been opened / closed, the process proceeds to step 407. If not, the process returns to step 401. In step 407, the control means 17 erases the contents stored in the open / close storage means 15. In step 408, the control means 17 causes the fully automatic washing machine 1 to start washing and returns to step 401.
[0028]
For example, when the user inputs the reservation time 3:00 pm to the reservation time setting means 13 at 10:00 am, since there is an input to the reservation time setting means 13 in step 401, the process proceeds to step 402. The time of 3 pm is stored, and the process returns to step 401. Next, when the lid 3 is opened and closed and the laundry is put in, the process proceeds to step 403 since there is no input to the reserved time setting means 13 in step 401, and the process proceeds to step 404 because the opening and closing of the lid is detected. In step 404, information that “the lid is open / closed” is stored in the open / close storage unit 15, and the process returns to step 401. Thereafter, if neither the input to the reservation time setting means 13 nor the opening / closing of the lid 3 is performed, there is no input to the reservation time setting means 13 in step 401 until the time reaches 3:00 pm. Since the lid open / close is not detected, the process proceeds to the sucking step 405, and the time indicated by the time measuring means 16 does not coincide with the reserved time, and the process of returning to step 401 is repeated. When the time is 3:00 pm, the time indicated by the time measuring means 16 in step 405 coincides with the reserved time, so the process proceeds to step 406. In step 406, the information “with lid open / closed” is stored in the open / close storage means 15; In step 407, the control unit 17 deletes the contents stored in the open / close storage unit 15. In step 408, the control unit 17 causes the fully automatic washing machine 1 to start washing and returns to step 401.
[0029]
Thereafter, if neither the input to the reservation time setting means 13 nor the opening / closing of the lid 3 is performed, the processes of step 401, step 403, step 405, and step 401 are repeated until 3:00 pm the next day. At 3:00 pm, the process proceeds from step 405 to step 406, and since the information “with lid open / closed” is not stored in the open / close storage means 15 at step 406, the process returns to step 401.
[0030]
When the lid 3 is opened and closed, the laundry is taken out and a new laundry is put in, the laundry is executed when the time coincides with the reserved time.
[0031]
It is obvious that the same effect can be obtained by using day of the week and time or date / time as the reservation time instead of the reservation time.
[0032]
【The invention's effect】
