If it is not detected that the door 2 is opened (“No” in Step # 11-12), the microcomputer 15 continues the operation stop state in Step # 11-4.

  Next, the microcomputer 15 determines based on the detection signal input from the state detection circuit 18 whether or not the door 2 detected to have been opened in step # 11-12 has been closed thereafter (step). # 11-15).

  If it is detected that the door 2 has been closed thereafter (“Yes” in Step # 11-15), the microcomputer 15 clears the timer that started the count in Step # 11-5 (Step S11-5). # 11-16) When the reservation key 26 input as an operation start instruction is detected after that, control is performed to validate the input (step # 11-17), and the processing state is set to the operation stop state. Shifts to the operation state and returns to step # 11-2. If it is not detected that the door 2 has been closed thereafter (“No” in step # 11-15), the microcomputer 15 stops the timer in step # 11-13 and the step # 11-14. The control for invalidating the input of the reservation key 26 is continued.

  As described above, the fully automatic washing machine according to the eleventh embodiment can perform re-detection of the cloth amount even after the door is opened and closed by performing the cloth amount detection determination again after shifting to the operation state. .

  As a result, the amount of cloth can be re-determined even after the user adds clothing, etc., so that an appropriate amount of detergent can be used, manufacturing costs do not increase, and no detergent is wasted. A safe and more convenient washing machine can be provided.

[Twelfth embodiment]
The configuration, functions, and layout of the input keys of the fully automatic washing machine according to the twelfth embodiment are the same as those of the fully automatic washing machine according to the first embodiment. The layout is the same as the input key layout. Also in this embodiment, the load drive circuit 21 included in the control unit 8 receives a control signal from the microcomputer 15 via the I / O port, and drives the door lock of the lid 2 according to the control signal. Then, the lid 2 is locked and unlocked. The state detection circuit 18 further includes a sensor that detects a locked / unlocked state of the door lock of the lid 2.

  The process in the fully automatic washing machine concerning 12th Embodiment is demonstrated using the flowchart of FIG. The process shown in the flowchart of FIG. 17 is also a process realized when the microcomputer 15 included in the control unit 8 controls various functions shown in FIG. 2 according to a program stored in the ROM 16. The process shown in the flowchart of FIG. 17 is an instruction to start operation when the reservation key 26 is pressed. As in the second embodiment, “reservation key input”, “elapse of a predetermined time”, Alternatively, “reservation key input or elapse of a predetermined time” is the operation start condition.

  Referring to FIG. 17, first, based on the signal information from input key circuit 17, the microcomputer 15 detects that the coarse key 30 and the power key 31 are simultaneously pressed, and the power is turned on. (Step # 12-1). Immediately thereafter, the microcomputer 15 executes a process for determining whether or not the cloth amount is detected based on the signal information from the input key circuit 17.

  As processing for determining the presence or absence of the cloth amount detection, the microcomputer 15 first determines whether or not the coarse key 30 has been pressed before the power is turned on based on signal information from the input key circuit 17 ( Step # 12-2). As a result, if it is determined that the course key 30 has been pressed before the power is turned on (“Yes” in step # 12-2), the microcomputer 15 starts the cloth operation in the initial operation state after the door 2 is opened and closed. It is confirmed that the amount detection is performed (step # 12-3).

  If it is not determined that the Kosky 30 has been pressed before the power is turned on (“None” in Step # 12-2), the microcomputer 15 detects the cloth amount in the initial operation state after the door 2 is opened and closed. It is confirmed that there is not (step # 12-4).

  The processing for determining the presence or absence of the above-described cloth amount detection is performed, and the microcomputer 15 controls the start of the operation of the fully automatic washing machine by pressing the start key 32 after the user performs the operation course and various settings. (Step # 12-5).

  When the operation of the fully automatic washing machine is started in step # 12-5, the amount of cloth stored in the washing and dewatering tub 5 is detected by the cloth amount detection means of the control unit 8 (step # 12-6). The water level and operation control necessary for washing are determined (step # 12-7).

  Thereafter, the microcomputer 15 shifts the processing state to the operation stop state (step # 12-8), and starts counting a timer that measures a predetermined time as one of the operation start conditions (step # 12-9). The process waits until a predetermined operation start condition is satisfied (step # 12-10).

  When it is detected that a predetermined operation start condition is satisfied (“Yes” in step # 12-10), the microcomputer 15 controls to lock the door (step # 12-11), and step # 12. The timer that started counting at -9 is cleared (step # 12-12).

  After clearing the timer in step # 12-12, the microcomputer 15 determines whether or not the cloth amount is detected (step # 12-13). As a result, the door 2 has not been opened and closed, and since it does not correspond to the initial operation state after the door 2 is opened and closed, it is determined that the cloth amount is not detected (“No” in step # 12-13), and the process is performed. The state is shifted from the operation stop state to the operation state, and control such as water supply is started (step # 12-14).

  While the predetermined operation start condition is not satisfied (“No” in step # 12-10), the microcomputer 15 compares the detection signal input from the state detection circuit 18 with the determination value stored in the ROM 16. Thus, it is determined whether or not the door lock can be released at present (step # 12-15). If it is determined that the door lock can be released (“Yes” in step # 12-15), the microcomputer 15 controls the door lock to be released (step # 12-16), and opens the door 2. Make it possible.

  If it is determined that the door lock cannot be released (“No” at step # 12-15), the microcomputer 15 starts predetermined operation until the door lock can be released or at step # 12-10. The shutdown state is continued until it is detected that the condition is satisfied.

  After controlling to release the door lock in step # 12-16, the microcomputer 15 determines whether or not the door 2 has been opened based on the detection signal input from the state detection circuit 18 (step # 12). -17).

  If it is detected that the door 2 is opened (“Yes” in step # 12-17), the microcomputer 15 stops the timer that started the count in step # 12-9 (step # 12— 18) When the reservation key 26 input as an operation start instruction is detected thereafter, the input is controlled to be invalidated (step # 12-19). If it is not detected that the door 2 is opened (“No” in Step # 12-17), the microcomputer 15 continues the operation stop state in Step # 12-8.

  Next, the microcomputer 15 determines based on the detection signal input from the state detection circuit 18 whether or not the door 2 detected to have been opened in step # 12-17 has been closed thereafter (step). # 12-20).

  If it is detected that the door 2 has been closed thereafter (“Yes” in step # 12-20), the microcomputer 15 detects that the reservation key 26 that has been input as an operation start instruction is detected thereafter. Then, the input is controlled to be valid (step # 12-21), the door is locked (step # 12-11), and the timer whose count was started in step # 12-9 is cleared. (Step # 12-12). If it is not detected that the door 2 has subsequently been closed (“No” in step # 12-20), the microcomputer 15 stops the timer in step # 12-18 and the step # 12-19. The control for invalidating the input of the reservation key 26 is continued.

  After clearing the timer in step # 12-12, the microcomputer 15 determines whether or not the cloth amount is detected (step # 12-13). As a result, when it is determined that the cloth amount detection is performed in the cloth amount detection presence / absence determination process described above (“Yes” in step # 12-13), step # 12-17 and step # 12 are performed. Since it is the initial operation state in which the opening / closing of the door 2 is detected at -20, the process returns to step # 12-6, and the cloth amount is detected again.

  If it is determined that the cloth amount is not to be detected in the cloth amount detection determination process described above ("No" in step # 12-13), the processing state is shifted from the operation stop state to the operation state. Then, control such as water supply is started (step # 12-14).

  As described above, the fully automatic washing machine according to the twelfth embodiment shifts to the operation state after shifting from the open state to the closed state in the operation stop state, and determines whether the cloth amount detection determination is performed again. By further providing means for enabling selection, it is possible to select whether to re-measure the amount of clothing.

  Therefore, the user can re-measure the amount of clothing, and can provide a washing machine tailored to the individual user that is safer and easier to use without significantly increasing the manufacturing cost.

[Thirteenth embodiment]
The configuration, functions, and layout of the input keys of the fully automatic washing machine according to the thirteenth embodiment are the same as those of the fully automatic washing machine according to the first embodiment. The layout is the same as the input key layout.

  The process in the fully automatic washing machine concerning 13th Embodiment is demonstrated using the flowchart of FIG. The process shown in the flowchart of FIG. 18 is also a process realized by the microcomputer 15 included in the control unit 8 controlling various functions shown in FIG. 2 in accordance with a program stored in the ROM 16. After performing the driving course and various settings, pressing the start key 32 starts the reserved driving in which the reserved time for which the driving end time can be specified is set (step # 13-1). The process shown in the flowchart of FIG. 18 is an instruction to start the operation when the reservation key 26 is pressed. As in the second embodiment, “reservation key input”, “elapse of a predetermined time”, Alternatively, “reservation key input or elapse of a predetermined time” is assumed to be the operation start condition, and in the following description, “reservation key input” is already determined as the operation start condition.

  Referring to FIG. 18, when the reservation operation of the fully automatic washing machine is first started in step # 13-1, when the reservation key 26 input as the operation start instruction is detected after that, Control is performed to invalidate the input (step # 13-2), and the operation start condition determined in “reservation key input” is changed to “elapse of a predetermined time (for example, 1 minute)”.

  Next, the amount of cloth accommodated in the washing and dewatering tub 5 is detected by the cloth amount detecting means of the control unit 8 (step # 13-3), and the water level and operation control required for washing are determined (step). # 13-4).

  Thereafter, the microcomputer 15 shifts the processing state to the operation stop state (step # 13-5), starts counting of a timer for measuring a predetermined time (step # 13-6), and performs a predetermined time which is an operation start condition. (Step # 13-7).

  When it is determined that the predetermined time as the operation start condition has elapsed (“Yes” in step # 13-7), the microcomputer 15 clears the timer that started the count in step # 13-6 (step # 13-6). # 13-8), shift to the reserved operation standby state (step # 13-9).

  As described above, the fully automatic washing machine according to the thirteenth embodiment enters the operation stop state after the cloth amount detection determination in the initial operation when the reservation operation in which the reservation time for specifying the operation end time is set is started. When the operation is stopped, the operation start instruction by the operation unit input means is invalidated, and the transition to the reserved operation standby state is made by the operation start instruction by the time elapse detection of the detection means detecting the elapse of the predetermined time from the operation stop state transition. Due to this, even when the operation start instruction by the operation unit input means is selected at the start of the reserved operation, the operation start instruction by the time elapse detection of the detection means detecting the elapse of the predetermined time from the operation stop state transition is made to the reserved operation standby state. Can be migrated.

  Therefore, even if the user has selected the operation start instruction by the operation unit input means at the start of the reserved operation, the reservation is made by the operation start instruction by the time elapse detection of the detection means detecting the elapse of the predetermined time from the operation stop state transition. Since it is possible to shift to the operation standby state, it is possible to eliminate the case where the user forgets the operation start instruction by the operation unit input means and the operation is not started, and the manufacturing cost does not increase, and it is safer and more operable. It is possible to provide a washing machine tailored to individual users.

[Fourteenth embodiment]
The configuration, functions, and layout of the input keys of the fully automatic washing machine according to the fourteenth embodiment are the same as those of the fully automatic washing machine according to the first embodiment. The layout is the same as the input key layout.

  The process in the fully automatic washing machine concerning 14th Embodiment is demonstrated using the flowchart of FIG. The process shown in the flowchart of FIG. 19 is also a process realized by the microcomputer 15 included in the control unit 8 controlling various functions shown in FIG. 2 in accordance with a program stored in the ROM 16. After setting the driving course and various settings, the reserved key is started by pressing the start key 32 (step # 14-1). The process shown in the flowchart of FIG. 19 is an instruction to start the operation when the reservation key 26 is pressed. As in the second embodiment, “reservation key input”, “elapse of a predetermined time”, Alternatively, “reservation key input or elapse of a predetermined time” is assumed to be an operation start condition, and in the following explanation, “elapse of a predetermined time (for example, 1 minute)” is already determined as an operation start condition. It shall be.

  Referring to FIG. 18, first, when the reservation operation of the fully automatic washing machine is started in step # 14-1, the cloth stored in the washing and dewatering tub 5 is detected by the cloth amount detecting means of the control unit 8. The amount is detected (step # 14-2), and the water level and operation control necessary for washing are determined (step # 14-3).

  Next, the microcomputer 15 compares the operation time with the reservation time (step # 14-4). If the operation time is longer than the reservation time ("Yes" in step # 14-4), then the microcomputer 15 When the reservation key 26 input as the operation start instruction is detected, the control is made to invalidate the input (step # 14-5), and then the operation start condition fixed at “elapse of a predetermined time” Is changed to “reservation key input or elapse of a predetermined time”.

  Thereafter, the processing state is shifted to the operation stop state (step # 14-6), and the count of a timer for measuring a predetermined time as the operation start condition is started (step # 14-7). The system waits until “reservation key input or predetermined time has elapsed” is satisfied (step # 14-8).

  When it is detected that the operation start condition “reservation key input or elapse of a predetermined time” is satisfied (“Yes” in step # 14-8), the microcomputer 15 counts in step # 14-7. The started timer is cleared (step # 14-9), the processing state is shifted from the operation stop state to the operation state, and control such as water supply is started (step # 14-10). That is, when the operation time is longer than the reserved time, after the operation start condition is satisfied, the process is shifted to the operation state instead of the reserved operation state.

  On the other hand, when the reservation time is longer than the operation time (“No” in step # 14-4), the processing state is shifted to the operation stop state (step # 14-11), and the predetermined time as the operation start condition is set. The counting of the timer to be measured is started (step # 14-12), and the process waits until a predetermined time as an operation start condition has elapsed (step # 14-13).

  If it is determined that the predetermined time as the operation start condition has elapsed (“Yes” in step # 14-13), the microcomputer 15 clears the timer that started the count in step # 14-12 (step # 14-12). # 14-14), it shifts to the reserved operation standby state (step # 14-15).

  As described above, the fully automatic washing machine according to the fourteenth embodiment further shifts to the operation stop state after the cloth amount detection determination at the initial stage of the wash operation when the reservation time is shorter than the operation time, and shifts to the operation stop state. Further, it is possible to shift to the driving state by a driving start instruction based on the detection of the elapse of time by a detecting means for detecting the elapse of a predetermined time or a driving start instruction by the operation unit input means.

  Therefore, even when the user has selected a driving start instruction by detecting the passage of time by the detection means that detects the passage of the predetermined time from the transition to the driving stop state when the reserved driving starts, the passage of the predetermined time from the transition to the driving stop state is detected Individual users who can move to the operating state by the operation start instruction based on the detection of the passage of time by the detection means or the operation start instruction by the operation unit input means, are safe and have good operability without increasing manufacturing costs A washing machine tailored to your needs can be provided.

[Fifteenth embodiment]
The configuration, functions, and layout of the input keys of the fully automatic washing machine according to the fifteenth embodiment are the same as those of the fully automatic washing machine according to the first embodiment. The layout is the same as the input key layout.

  The process in the fully automatic washing machine concerning 15th Embodiment is demonstrated using the flowchart of FIG. The process shown in the flowchart of FIG. 20 is also a process realized by the microcomputer 15 included in the control unit 8 controlling various functions shown in FIG. 2 in accordance with a program stored in the ROM 16. After setting the driving course and various settings, the driving is started by pressing the start key 32 (step # 15-1). Note that the processing shown in the flowchart of FIG. 20 is an instruction to start operation when the reservation key 26 is pressed, and as in the second embodiment, “reservation key input”, “elapse of a predetermined time”, Alternatively, “reservation key input or elapse of a predetermined time” is assumed to be the operation start condition, and in the following description, “reservation key input” is already determined as the operation start condition.

  Referring to FIG. 20, first, when the operation of the fully automatic washing machine is started in step # 15-1, the amount of cloth accommodated in the washing and dewatering tub 5 by the cloth amount detection means of the control unit 8. Is detected (step # 15-2), and the water level and operation control necessary for washing are determined (step # 15-3).

  Thereafter, the processing state is shifted to the operation stop state (step # 15-4), and an error detection timer for measuring a predetermined time for error detection (for example, 40 seconds) is determined in order to determine that an elapse of the predetermined time is an error. The count is started (step # 15-5), and the process waits until the reservation key 26 that is the operation start condition is pressed (step # 15-6).

  When it is detected that the reservation key 26 is pressed (“Yes” in step # 15-6), the microcomputer 15 shifts the processing state from the operation stop state to the operation state and starts control such as water supply. (Step # 15-7).

  While it is not detected that the reservation key 26 has been pressed (“No” in step # 15-6), the microcomputer 15 monitors the passage of a predetermined time for error detection while the operation is stopped (step # 15—). 8). When the passage of a predetermined time for error detection is detected (“Yes” in step # 15-8), an error is displayed in a predetermined area of the display unit 25 (step # 15-9). An error notification sound indicating that effect is output from the buzzer 20 (step # 15-10).

  Thereafter, the error detection timer whose counting was started in step # 15-5 is cleared (step # 15-11), and the processing state is shifted from the operation stop state to the error state (step # 15-12). Here, the error state is a state in which an error display is continuously displayed in a predetermined area of the display unit 25 and only the power key 31 and the reservation key 26 that is an operation start condition are accepted. When the reservation key 26 is pressed in such an error state, the operation state is shifted from the error state. On the other hand, when the power key 31 is pressed, the power is turned off. If nothing is pressed, the error state continues.

  As described above, in the fully automatic washing machine according to the fifteenth embodiment, the operation unit input means is the operation start instruction from the operation stop state, and the operation unit input means also instructs the operation start after the predetermined time has elapsed in the operation stop state. In the case where no operation has been performed, an error is displayed on the display means, and an error notification sound is notified to notify that the operation start instruction has not been issued.

  Therefore, it is possible to inform the user that the operation start instruction has not been made, and it is possible to provide a safe and high-quality washing machine without increasing the manufacturing cost.

  In addition, the predetermined time for error detection is made longer than the predetermined time that is the operation start condition so that the predetermined time for error detection described above is 1 minute and 30 seconds and the predetermined time that is the operation start condition is 1 minute. Therefore, it is possible to prevent the processing state from shifting to the error state before the predetermined time as the operation start condition elapses, and to improve the usability.

  That is, the above-described fully automatic washing machine has the same time as the predetermined time by making the error detection time until the error detection equal or longer than the predetermined time of the detection means for detecting the passage of the predetermined time from the operation stop state transition. It is possible to inform that the operation start instruction has not been made even after elapse of.

  Therefore, no error is detected before a predetermined time elapses from the operation stop state transition, and the user can be informed that the operation start instruction has not been made even after the elapse of the predetermined time from the operation stop state transition. A safer and higher quality washing machine can be provided.
