However, the general washing machine tends to emphasize the reduction of the operating time in the laundry operation, not the reservation operation. For example, it increases the rotation speed of the motor, improves the rotation speed of the laundry in the washing tub, do. However, when the rotation speed is increased, the laundry easily breaks and wrinkles. Therefore, in order to reduce the operation time and ensure the washing power, the laundry should be sacrificed to some extent.

On the other hand, the washing machine having the above-mentioned reservation operation function starts the washing operation after the reservation waiting time has elapsed, and generally carries out the normal washing operation and the reserved operation under substantially the same conditions. Therefore, in the washing machine disclosed in Patent Document 1, the operating time (execution time) of each process in the general washing operation and the reserved operation and the rotational speed of the motor in each process are considered to be substantially the same, Even in the case of a reservation operation that does not need to consider shrinkage, there is room for improvement when considering the aspect of sacrificing the integrity of the laundry.

 SUMMARY OF THE INVENTION It is an object of the present invention to provide a washing machine capable of performing a reservation operation that emphasizes washing conditions such as clothes and the like, while ending the washing until the scheduled closing time.

In order to achieve the above object, the present invention uses the following measures:

≪ First Embodiment >

1 is a perspective view showing the appearance of a vertical washing machine (hereinafter referred to as "washing machine") 1 according to a first embodiment of the present invention. 2 is a longitudinal sectional view showing a rough structure of the washing machine 1 according to the first embodiment.

The washing machine 1 according to the present embodiment includes a washing machine main body 2, an outer tub 3, a washing tub 3, a pulsator 5, a driving unit 6, and a control unit 7 ). The washing machine 1 can execute a plurality of processes of washing the clothes until the expected completion time inputted by the input unit 23, that is, the washing operation, the intermediate dewatering process, the rinsing process and the final dewatering process Reservation laundry).

The washing machine main body 2 has a substantially rectangular parallelepiped shape, and an opening 21 for inserting or removing laundry, which is a laundry, into the washing tub 4 is provided on the upper surface 20 thereof. And the opening and closing cover 22 for opening and closing the opening 21 can be opened and the clothes can be put into or taken out of the washing tub 4 through the opening 21 by opening the opening and closing cover 22. [ In addition, the upper surface 20 of the washing machine main body 2 is provided with a reservation operation course button, a time setting button, an operation start button, and the like, and an input unit 23 for arbitrarily inputting a washing course, (See Fig. 1).

The outer tub 3 shown in Fig. 2 is a tubular member disposed inside the washing machine body 2 and having a bottom capable of storing water.

The washing tub 4 is a tubular member disposed coaxially with the outer tub 3 inside the tub 3 and having a bottom supported freely rotatably by the tub 3. The diameter of the washing tub 4 is smaller than the diameter of the outer tub 3, and a plurality of water holes (not shown) are formed on the wall surface of the washing tub 4, thus functioning as a dewatering tank. In the washing process and the rinsing process, a water flow is generated through the water hole (not shown), and in the intermediate water dehydration process and the final water dehydration process, water is discharged from the drain hole (not shown) provided in the outer tub 3 through the water hole .

The pulsator (stirring blade) 5 is freely rotatably disposed at the center of the bottom portion 41 of the washing tub 4 and generates water flow by stirring the water stored in the tub 3. The faster the rotating speed of pulsator 5, the larger the flow value. In addition, the larger the ratio of the rotational time of the pulsator 5 to the execution time of each process to be described later, the larger the water flow value.

The driving unit 6 includes a motor 61 and a clutch 62. The motor 61 rotates the washing tub 4 and the pulsator 5 and generates a driving force for rotating the clothes accommodated in the washing tub 4 to provide.

Specifically, the motor 61 rotates the driving shaft 63 extending toward the bottom portion 41 of the washing tub 4, whereby the washing tub 4 is rotated. In addition, since the rotational force generated by the motor 61 is switched by the clutch 62, a driving force is similarly applied to the pulsator 5 to cause the pulsator 5 to rotate. Therefore, in a plurality of processes of washing clothes, the washing machine 1 rotates only the pulsator 5 mainly in the washing process and the rinsing process. In the intermediate dehydration process and the final dehydration process, the washing tub 4 and the pulsator 5 ) Are integrally rotated at a high speed.

3 is a block diagram showing the electrical structure of the washing machine 1 according to the present embodiment. The operation of the washing machine 1 is controlled through a control unit 7 including a microcomputer. The control unit 7 includes a ROM 71 and a RAM 72 and executes a program stored in the ROM 71 via a microcomputer to execute a predetermined operation. And temporarily stores data (e.g., expected end time input by the input unit 23) used in executing the program in the RAM 72. [

A water supply valve 24 for supplying water to the outer tank 3 and a drain valve 5 for discharging water in the outer tank 3 are connected to the control unit 7 in addition to the motor 61 and the clutch 62, have. It should be noted that the illustration of the water supply valve 24 and the drain valve 25 is omitted in FIG.

In addition to the signals generated by the input unit 23, the control unit 7 is also provided with a load sensor 26, a time acquiring unit 27, a timer 28, a water level sensor 29, Is also input.

The load sensor 26 detects the weight of the clothes accommodated in the washing tub 4 and the control unit 7 judges (calculates) the amount of load corresponding to the amount of clothes in accordance with the result of detection by the load sensor 26. The control unit 7 controls the data such as the rotational speed and the execution time of the motor 61, which will be described later, obtained from the ROM 71 by using the load amount, or adjusts the value corresponding to the load amount in the table stored in the ROM 71 And the washing time is set to be longer as the amount of clothes in the same mode is larger or the quantity of water supplied to the outer tub 3 is larger. It should be noted that the amount of load may be determined according to the quantity input by the input unit 23. [ In addition, the load can be adjusted by multiplying the data obtained from the ROM 71 by the load coefficient.

When the reserved operation course is selected, the time acquiring unit 27 acquires the remaining time to the end target time set by the control unit 7 in accordance with the scheduled end time inputted by the input unit 23. [ The end target time is set to a time earlier than the scheduled end time by a predetermined time. Preferably, the predetermined time is 30 minutes, more preferably 15 minutes. Even if it is necessary to carry out an irregular work by setting the end target time, for example, water is injected to solve the deviation of clothes in the washing tub 4 during the dehydration process, So that the washing can be completed within a period of time until the scheduled end time. In addition, for example, it is possible to cover the time loss by setting the predetermined time to 30 minutes or less, and it is possible to prevent the clothes from being left in the washing tub 4 and smell after the reservation work. In the present embodiment, the time acquiring unit 27 acquires the first of the plurality of processes for washing clothes, that is, the time remaining before the washing process starts.

The timer 28 acquires the elapsed time from the beginning in each process. The water level sensor 29 detects the quantity in the outer tank 3.

When the washing machine 1 according to the present embodiment selects the reserved operation course, compared with the normal reservation mode or the general reservation mode in which the average rotation speed of the motor 61 is set to a predetermined value and is executed within a predetermined execution time It is possible to execute the special reservation mode in which the average rotation speed of the motor 61 is smaller and the execution time is longer and the control unit 7 can execute each process in the normal reservation mode or the normal reservation mode according to the remaining time acquired by the time acquisition unit 27 And determines whether to execute in the special reservation mode. That is, the control unit 7 also functions as a mode determination unit.

Here, the average rotational speed of the motor 61 means an average rotational speed of the motor 61 that executes each process, and is defined according to each process. In the present embodiment, the average rotational speed of the motor 61 is adjusted by changing the rotational speed of the motor 61 in accordance with the rotational speed of the motor 61 obtained from the ROM 71, for example, by an inverter control method .

Although a general laundry course other than the reservation operation course emphasizes washing with reduced operation time, even if the operation time becomes long on the reservation operation course, the washing operation can be finished until the end reservation time. In the special reservation mode, the average rotation speed of the motor 61 is relatively small as compared with the general reservation mode, so that the rotation speed of the laundry in the washing tub 4 can be lowered to reduce the damage and wrinkles of laundry, The rotation speed of the clothes in the washing tub 4 is reduced, and the washing, rinsing, and dehydrating power of each unit time can be compensated. Therefore, in the washing machine 1 of the present embodiment, the special reservation mode can be executed if there is a time margin within the period to the end target time set based on the scheduled end time, And a reserving operation that emphasizes washing power.

The ROM 71 stores the rotation speed and execution time (washing time, intermediate dehydration time, rinsing time, final dehydration time) of the motor 61 in the normal reservation mode and the rotational speed of the motor 61 in the special reservation mode (Wash time, intermediate dehydration time, rinsing time, final dehydration time) and the like are stored in advance.

Specifically, the ROM 71 stores the normal laundry time applied in the normal reservation mode and the special reserved laundry time applied in the special reservation mode as the laundry time, respectively. In addition, the ROM 71 stores the general flow value applied in the normal reservation mode and the special reservation mode flow value applied in the special reservation mode, respectively, as the flow values. The water flow value is adjusted by adjusting the rotation speed of the motor and the special reservation mode water flow value is set smaller than the general water flow value. In addition, the water flow value can be adjusted by adjusting the ratio of the rotation time of the pulsator 5 to the execution time of each process.

In addition, the ROM 71 stores the normal intermediate dehydration time applied in the normal reservation mode and the special reserved intermediate dehydration time applied in the special reservation mode, respectively. In addition, the ROM 71 stores the normal rotation speed applied in the normal reservation mode and the special reservation mode rotation speed applied in the special reservation mode as the motor rotation speed, respectively. The special reservation mode rotation speed is set to a value smaller than the normal rotation speed.

In addition, the ROM 71 stores the general rinse time applied in the normal reservation mode and the special reserved rinse time applied in the special reservation mode as the rinse time, respectively. In addition, when the water flow values are different in the washing process and the rinsing process of the same mode, the normal water flow value applied in the normal reservation mode and the special reservation mode water flow value applied in the special reservation mode are respectively set as the water flow values for the rinsing process .

In addition, the ROM 71 stores the general final dehydration time applied in the normal reservation mode and the special reserved final dehydration time applied in the special reservation mode as the final dehydration time, respectively. In addition, when the rotational speed of the motor is different in the middle dewatering process and the final dewatering process in the same mode, the normal rotation speed applied in the normal reservation mode and the special reservation mode rotation speed applied in the special reservation mode are further subjected to the final dehydration process Respectively.

Therefore, the average rotation speed of the motor 61 when the special reservation mode is set is smaller than that when the general reservation mode is set.

<Step SP57>

In step SP57, the control unit 7 determines whether the final dehydration time set in step SP52 or step SP54 has been reached or not in accordance with the elapsed time obtained by the timer 28. [

<Step SP58>

When the final dehydration time is reached at step SP58, the control unit 7 ends the final dehydration operation.

When the remaining time acquired through the time acquiring unit 27 is determined to be equal to or longer than the time required for the special reservation mode, the entire process is executed in the special reservation mode. Otherwise, the process is executed in the normal reservation mode, It is possible to realize the reservation operation for reducing the breakage and wrinkling of the clothes through simple control.

&Lt; Second Embodiment >

10 is a flowchart showing the flow of judgment of the reservation mode of the washing machine according to the second embodiment of the present invention. A part of the determination flow of the reservation mode of the washing machine 1 according to the present embodiment is different from the first embodiment. Except for the method described below, the method is the same as that of the first embodiment, and a description thereof will be omitted.

&Lt; Step SP15 &

In step SP15, the control unit 7 determines whether or not the time remaining until the end target time acquired by the time obtaining unit 27 is equal to or longer than the time required for the special reservation mode, If it is determined that the time required for the reserved mode is longer than the time required for the reserved mode, the process proceeds to step SP16 (step SP15: YES).

&Lt; Step SP18 &

In step SP18, the control unit 7 determines whether or not a part of the process can be executed in the special reservation mode. Specifically, the remaining time acquired by the time acquiring unit 27 is used to perform a part of the washing process, the intermediate dehydration process, the rinsing process, and the final dehydration process (for example, the intermediate dehydration process and the final dehydration process) And judges whether or not the time required for other processes (for example, the washing process and the rinsing process) is executed in the normal reservation mode. It should be noted that the required time is a time obtained from data previously stored in the ROM 71 according to the load. If it is determined that the remaining time is longer than the time required for executing the partial process in the special reservation mode and executing the other process in the general reservation mode, the process proceeds to step SP19 (step SP18: YES) (NO in step SP18), the process proceeds to step SP20.

<Step SP19>

In step SP19, the control unit 7 executes a partial process in the special reservation mode and determines to execute the other process in the general reservation mode.

<Step SP20>

In step SP20, the control unit 7 determines to execute the entire process in the normal reservation mode.

After the determination step SP1A of the reservation mode as described above, the control unit 7 determines whether the reservation mode is selected according to the order of the washing process SP2, the intermediate dehydration process SP3, the rinsing process SP4 and the final dehydration process SP5 shown in Figs. 6 to 9 Proceed with the operation.

In this way, when the time is not sufficient to perform the entire process in the special reservation mode, it is possible to increase the opportunity to execute the reservation operation to reduce the damage and wrinkles of the clothes by executing only a partial process in the special reservation mode.

&Lt; Third Embodiment >

11 to 15, a flow of a situation in which the washing machine according to the third embodiment of the present invention executes the reservation operation will be described. 11 is a flowchart showing a flow of a situation of washing in a reservation operation course. 12 is a flowchart showing the flow of the washing process SP2a in the reserved operating course. Fig. 13 is a flowchart showing the flow of the intermediate dewatering process SP3a in the reserved operation course. 14 is a flowchart showing the flow of the rinsing process SP4a in the reservation operating course. 15 is a flowchart showing the flow of the final dewatering process SP5a in the reservation operation course.

In the present embodiment, the time acquisition unit 27 (see FIG. 3) is provided before the start of the intermediate dewatering process SP3a, before the start of the rinsing process SP4a, and before the start of the final dewatering process SP5a The remaining time to the end target time is obtained.

In addition, each time the time acquisition unit 27 acquires the remaining time, the control unit 7 determines whether to perform the next process in the normal reservation mode or the special reservation mode according to the remaining time.

Concretely, in the approximate flow in the case where washing is performed in the reserved operating course shown in Fig. 11, first, the operating course is set in step SP1a. The flow of setting the operation course in step SP1a is the same as that in steps SP11 to SP14 shown in Fig. Next, the washing process SP2a, the intermediate dewatering process SP3a, the rinsing process SP4a, and the final dewatering process SP5a are executed in order.

The washing process of step SP2a shown in FIG. 12 is a step SP21a for judging whether or not the remaining time acquired by the time obtaining unit 27 is equal to or longer than the time required for the first special reservation mode, This is the same as the flow of the washing process SP2 shown in Fig. 6, except for replacing the step SP21. The time required for the first special reservation mode is a time required for executing the washing process SP2a, the intermediate dehydration process SP3a, the rinsing process SP4a, and the final dehydration process SP5a in the special reservation mode. If it is determined that the remaining time is equal to or longer than the time required for the first special reservation mode, the process proceeds to step SP22. If it is determined that the remaining time is not longer than the time required for the first special reservation mode, the process proceeds to step SP24.

The intermediate dehydration process of step SP3a shown in FIG. 13 is a step SP31a for judging whether the remaining time acquired by the time acquisition unit 27 is equal to or longer than the time required for the second special reservation mode, Is the same as the flow of the intermediate dewatering process SP3 shown in Fig. 7, except that the step SP31 is replaced. The time required for the second special reservation mode is a time required for executing the intermediate dehydration process SP3a, the rinsing process SP4a, and the final dehydration process SP5a in the special reservation mode. If it is determined that the remaining time is equal to or longer than the time required for the second special reservation mode, the process proceeds to step SP32. If it is determined that the remaining time is not longer than the time required for the second special reservation mode, the process proceeds to step SP34.

The rinsing process of step SP4a shown in FIG. 14 is a step SP41a for judging whether or not the remaining time acquired by the time obtaining unit 27 is equal to or longer than the time required for the third special reservation mode, Is the same as the flow of the rinsing process SP4 shown in Fig. 8, except that step SP41 shown in Fig. The time required for the third special reservation mode is a time required for executing the rinsing process SP4a and the final dehydration process SP5a in the special reservation mode. If it is determined that the remaining time is equal to or longer than the time required for the third special reservation mode, the process proceeds to step SP42. If it is determined that the remaining time is not longer than the time required for the third special reservation mode, the process proceeds to step SP44.

The final dehydration process of step SP5a shown in Fig. 15 is a step SP51a for judging whether or not the remaining time acquired by the time acquisition unit 27 is equal to or longer than the time required for the fourth special reservation mode, Is the same as the flow of the final dewatering process SP5 shown in Fig. 9, except that step SP51 shown in Fig. The time required for the fourth special reservation mode is a time required for executing the final dehydration process SP5a in the special reservation mode. If it is determined that the remaining time is equal to or longer than the time required for the fourth special reservation mode, the process proceeds to step SP52. If it is determined that the remaining time is not longer than the fourth special reservation mode required time, the process proceeds to step SP54. It should be explained that the control unit 7 proceeds the judgment in steps SP21a to SP51a. In addition, the time required for the first to fourth special reservation modes is a time obtained from data previously stored in the ROM 71 according to the load.

In this way, it is necessary to review whether to execute the general reservation mode or the special reservation mode before starting each of the processes SP2a, SP3a, SP4a, and SP5a, so that even if time loss occurs, The washing can be ended.

It should be noted that the specific structure of each part is not limited to the above embodiment.

For example, in the above embodiment, the rotational speed of the motor 61 is changed through the special reservation mode rotation speed or the general rotation speed obtained from the ROM 71 to adjust the average rotation speed of the motor 61 The present invention is not limited to the above method and may be modified by changing the proportion of the operating time and the stopping time of the motor 61 in each process by controlling the operation of the motor 61, Value. It should be noted that in this case, the flow rate of the washing process and the rinsing process can be adjusted by controlling the ratio of the rotation time of the pulsator 5 to the execution time of each process.

In the above embodiment, although the end target time is set earlier than the end scheduled time, the end target time may be set to the same time as the end scheduled time.

In addition, although the above-described embodiment is the vertical washing machine 1, the reservation operation can also be performed in the drum washing machine. In this case, the motor 61 rotates the washing tub.
