Description

  The present invention relates to a fully automatic washing / drying machine that performs fully automatic operations from washing to drying of clothes, and in particular, a user responds to the situation in consideration of the importance of electricity charges and life rhythm (action schedule). The present invention relates to a fully automatic washing and drying machine that can be automatically operated in an optimal time zone.

  The fully automatic washing machine can automatically execute water supply, washing, rinsing, and dehydration processes continuously so that the user can reserve the washing start time and washing end time and can start operation according to the reservation conditions. There are many things like this. When a user makes a reservation, the user may desire a reservation condition that the user can use the cheap electric power and end the next morning, regardless of the operation start time. In response to these demands, it is judged whether there is a low-night electricity time zone where the unit price of electricity is low before the scheduled laundry end time, and if there is, fully automatic washing is made to operate during that late-night electricity hour zone. A machine has also been developed.

  For example, in Patent Document 1, when there is a midnight power time zone (priority time zone) where the power unit price is low by the reserved washing end time, washing is performed during the priority time zone, and only the rinsing process is executed. A fully automatic washing machine is disclosed in which a dehydration process is performed immediately before a reserved washing end time and all processes are completed at the reserved washing end time. However, such a manner of operation is not appropriate for a fully automatic washing / drying machine that performs fully automatic drying.

Further, in Patent Document 2, when there is a midnight power time zone where the power unit price is low by the reserved washing end time, the operation start time is set so that the washing operation is completed at the end time of the midnight power time zone. A fully automatic washing machine determined by back calculation is disclosed. However, in the case of this washing machine, the required washing time used when the operation start time is calculated backward is fixed. In general, the optimum time for the washing time varies depending on the weight of clothes to be washed. If the time required for washing is set to a certain time, there arises a disadvantage that optimal washing cannot be performed or that the operation is performed in a time zone that is out of the midnight power time zone due to the difference in the required time.

The blower fan 42 sucks the circulating air that has passed through the ventilation duct 23 and blows it out from an outlet 44 formed in the upper portion of the casing 41.

  The circulating air blown out from the outlet 44 rotates with the connection hose 46, the air supply duct 47, the warm air passage 51 provided on the back side of the water tank 4, the opening 50 provided on the back plate of the water tank 4, and the back plate of the water tank 4. The hot air is introduced into the rotary tank 2 through the hot air introduction path 55 provided between the tank 2 and the back plate of the tank 2 and the numerous small holes 13 provided in the back plate of the rotary tank 2.

  On the other hand, an air suction port 30 is formed at the front end of the ventilation duct 23 upward, and a connection hose 33 and an air suction duct 32 connected thereto are attached to the air suction port 30. The air intake duct 32 is connected to a hot air outlet 31 formed above the opening 6 of the water tank 4 in order to discharge the air in the rotating tank 2.

  With such a structure, the drying air is sent out from the air intake duct 32 by the blower fan 42, enters the rotary tub 2 from the back side of the rotary tub 2, contacts the clothing, and after the contact, the front side of the rotary tub 2 It circulates in the path | route which goes out from the warm air outlet 31 of this, and returns to the ventilation duct 23 again.

  Next, the configuration of the control device of the fully automatic washing and drying machine 1 will be described with reference to the block diagram shown in FIG. The control device 70 includes a control circuit 71, an operation panel 72, a sensor group 73, a drive circuit group 74, and a communication device 75.

  The control circuit 71 has a function of controlling the overall operation of the fully automatic washing and drying machine 1 and is mainly composed of a microcomputer. Inside, a known CPU, RAM, ROM, nonvolatile memory, a bus (not shown) for connecting them, an I / O interface, a power supply device, and the like are provided. The operation panel 72 functions as a man-machine interface with the user. The operation switch group 72a is used for inputting washing conditions and drying conditions, selecting an operation mode to be described later, and the input information and operation status. It is comprised by the display apparatus 72b for displaying. FIG. 3 is a configuration example of the panel surface of the operation panel 72.

  The sensor group 73 drives a water level sensor 73a for detecting the water level in the water tank 4, a rotary tank outlet air temperature sensor 73b for detecting the temperature of the drying air, a rotary tank inlet air temperature sensor 73c, and the rotary tank 2. A rotational position sensor 73d for detecting the rotational position of the motor 18 is included.

  The drive circuit group 74 includes a rotary tank drive circuit 74a that drives the motor 18 that rotates the rotary tank 2, a blower drive circuit 74b that drives the motor 43 of the blower 40 that circulates the drying air, and the compressor 26 that constitutes the heat pump device. , A compressor drive circuit 74c for driving the water, a water supply valve drive circuit 74d for driving a water supply valve (not shown) for controlling water supply into the water tank 4, and a drain valve 37 for controlling the discharge of water in the water tank 4. A drain valve drive circuit 74e is included.

As will be described later, the communication device 75 is for receiving information related to the amount of power generated by the auxiliary power feeding device.
Under the above configuration, in the water supply process which is the first process of the washing and drying process, the water supply valve drive circuit 74d opens the water supply valve to start water supply into the water tank 4, and the water level has reached a predetermined level. Water supply is detected by the water level sensor 73a. In the next washing step, the motor 18 is driven by the rotating tub drive circuit 74a to rotate the rotating tub 2 forward and backward in a predetermined cycle, thereby washing clothes. In the subsequent rinsing step, the rinsing process is performed by repeating a series of operations of drainage, water supply, and forward / reverse rotation of the rotating tub 2 several times. In the subsequent dewatering step, the drain valve 37 is opened to drain the water in the water tank 4, and then the rotating tank 2 is rotated at a high speed by the motor 18 to dehydrate the clothes.

  In the final drying process, the compressor 26 is driven by the compressor drive circuit 74c to operate the heat pump device. At the same time, the motor 43 of the blower 40 that circulates the drying air is driven by the blower drive circuit 74 b, and the rotary tank 2 is driven to rotate by the motor 18. As a result, the circulating air that has absorbed the moisture of the clothes in the rotary tub 2 is sucked into the air intake duct 32 from the hot air outlet 31. The sucked circulating air comes into contact with a low-temperature evaporator 24 installed in the ventilation duct 23. The circulating air is cooled, moisture is condensed and dehydrated and dried. The dried circulating air then comes into contact with the high-temperature condenser 25 to become high-temperature dry air, and is blown into the rotary tub 2 through the air supply duct 47. As the circulating air circulates in this way, the clothes are deprived of moisture and dried.

  Next, in consideration of the features of the present invention, that is, the degree of importance of electricity charges for the washing and drying and the life rhythm (behavior schedule), the fully automatic washing and drying machine 1 is set in the optimum time zone according to the situation. A control method capable of automatic operation will be described with reference to the control flow shown in FIG.

  This control flow is a flow executed by the control circuit 71 and is started when the power supply button 72c is pressed and power is supplied to the control device 70. In the first step S1, it is checked whether or not the start button 72d on the operation panel 72 has been pressed.

  The process proceeds to step S2 after being pushed. In step S2, the weight of the laundry put in the rotating tub 2 is detected. The weight detection is performed by supplying a predetermined voltage to the motor 18 for a certain period of time and measuring the number of rotations of the rotary tank 2 during that time. The rotation speed of the rotary tank 2 is measured using a rotation position detection sensor 73d. The number of rotations when a constant voltage is applied to the motor 18 for a certain period of time according to the weight of the garment is measured and tabulated in advance, and the weight of the garment put in is determined based on the measured number of rotations against the table.

  In the subsequent step S3, the operation time and power consumption of each process corresponding to the detected clothing weight, that is, each process of water supply, washing, rinsing, dehydration and drying are obtained. The operation required time for each process corresponding to the weight of the garment is created by experimenting and stored in the control circuit 71 as a table as shown in FIG. In this table, the total process time T0 and the drying priority time Ta described later are also described. The power consumption in each step is also experimented for each clothing weight to create data and stored in the control circuit 71 as a table as shown in FIG. The control circuit 71 reads the detected clothing weight against the tables of FIGS. 5 and 6 and reads the operation time required for each process and the power consumption for each process.

  In the subsequent step S4, the midnight power time zone (priority time zone, for example, the time zone from 23:00 to 7 o'clock), the power unit price, and the power unit price in the normal time zone are read. Further, the unit price of power supplied from a cogeneration system as described later is also read out. These time zones and power unit prices are stored in the control circuit 71 in advance.

  In the following step S5, an operation start time, an expected operation end time, and a guideline for the electric charge for the following five operation modes are calculated. The operation start time is the time at which the water supply process is started, and the operation end expected time is the time at which the drying process is expected to end. Hereinafter, the calculation method of the operation start time Tf, the expected operation end time Te, and the standard of the electric charge for the five operation modes of the normal operation mode and the operation modes 1 to 4 provided in the fully automatic washing and drying machine 1 of the present embodiment will be described. To do.

  The normal operation mode is an operation mode in which operation is started immediately (a water supply process is started). The operation start time Tf in this mode is the current time T1, and the expected operation end time Te is a time (T1 + T0) obtained by adding the total process time T0 read from FIG. 5 to the current time T1. The guideline for the electricity charge required for the operation is that the operation start time Tf is the current time T1, the operation required time of each process is known from FIG. 5, and the power consumption in each process is known from FIG. Since the power unit price for each time zone has been determined in step S4, it can be calculated using those numerical values.

  The operation mode 1 is an operation mode in which cheap electricity is maximized by using cheap midnight power to the maximum. Accordingly, in the operation mode 1, when the current time T1 is not in the midnight power time zone, the operation start time Tf is changed to the start time TA (for example, 23:00) as shown in (1) of FIG. ). Wait from the current time T1 to the start time TA of the midnight power time zone.

  When the current time T1 is in the midnight power time zone, the current time T1 is set as the operation start time Tf as shown in (2) of FIG. The expected operation end time Te is a time (Tf + T0) obtained by adding the total process time T0 read from FIG. 5 to the operation start time Tf determined as described above. Since the operation start time Tf is known, the standard of the electricity charge necessary for the operation can be calculated in the same manner as in the normal operation mode.

  The operation mode 2 is an operation mode in which only a drying process with high power consumption is executed in the late-night power hours where the power unit price is low. In this mode, the operation start time Tf in that case is calculated backward using FIG. 5 so that the drying process is started at the start time TA of the midnight power period. When the back-calculated operation start time Tf is after the current time T1, the back-calculated time is set as the operation start time Tf. (See (1) in FIG. 8). It waits from the present time T1 to the operation start time Tf calculated backward.

  If the calculated operation start time Tf is before the current time T1, the current time T1 is set as the operation start time Tf (see (2) in FIG. 8). Even when the current time T1 is in the midnight power time zone, the current time T1 is set as the operation start time Tf as shown in (3) of FIG. The expected operation end time Te is a time (Tf + T0) obtained by adding the total process time T0 read from FIG. 5 to the operation start time Tf determined as described above. Since the operation start time Tf is known, the standard of the electricity charge necessary for the operation can be calculated in the same manner as in the normal operation mode.

  In operation mode 3, of the time required for the drying process with high power consumption, a predetermined second half time (hereinafter referred to as drying priority time Ta) is a midnight power time zone where the unit price of electricity is low, and the remaining first half is a normal time. This is an operation mode executed in the belt. This drying priority time Ta is determined in advance as shown in the table of FIG. In this mode, out of the time required for the drying process, the operation start time Tf in this case is calculated backward using FIG. 5 so that the drying process of the drying priority time Ta is started from the start time TA of the midnight power time zone. To do. When the back-calculated operation start time Tf is after the current time T1, the back-calculated time is set as the operation start time Tf. (See (1) in FIG. 9). It waits from the present time T1 to the operation start time Tf calculated backward.

  If the calculated operation start time Tf is before the current time T1, the current time T1 is set as the operation start time Tf (see (2) in FIG. 9). Even when the current time T1 is in the midnight power time zone, the current time T1 is set as the operation start time Tf as shown in (3) of FIG. The expected operation end time Te is a time (Tf + T0) obtained by adding the total process time T0 read from FIG. 5 to the operation start time Tf determined as described above. Since the operation start time Tf is known, the standard of the electricity charge necessary for the operation can be calculated in the same manner as in the normal operation mode.

  The operation mode 4 is an operation mode that can be used when the power supply is received not only from a commercial power source of an electric power company but also from a cogeneration system using a fuel cell, a solar cell, or the like. The unit price of power supplied from the cogeneration system is usually lower than the unit price of commercial power. For this reason, in this operation mode, a series of washing and drying operations are performed during a period in which the power from the cogeneration system can be used.

  In order to confirm whether or not the power from the cogeneration system can be used, information on the amount of generated power is received via the communication device 75. In the operation mode 4, the operation is started when the received amount of generated electric power becomes a predetermined value or more. After the amount of generated power becomes equal to or higher than a predetermined value and the operation is started, even if the amount of generated power returns to a predetermined value or less, the operation is not stopped and the operation is continued until the end of the last process. In this case, the standard of the electricity charge is a value obtained by multiplying the required total expected electric energy by the power unit price of the cogeneration system.

  In step S5, if the operation start time, the expected operation end time, and the electric charge guideline for the above five operation modes are calculated, the values are temporarily stored, and the process proceeds to the next step S6. In step S6, the operation mode at the previous operation is read out. The operation mode at the previous operation is stored in the nonvolatile memory in the control circuit 71 at the previous operation.

  In the next step S7, the estimated operation end time Te calculated in step S5 and the standard of the electric charge for the read operation mode are displayed on the display device 72b on the operation panel 72. An example of the display is shown in FIG. (1)-(5) of FIG. 10 has shown the example of a display of the operation mode 1, the operation mode 2, the operation mode 3, the normal operation mode, and the operation mode 4 in order. Which operation mode is displayed is indicated by lighting the display lamp 72e attached to the upper right part. If displayed, the process proceeds to step S8. In step S8, the control circuit 71 resets and starts the internal software timer.

  The user determines whether or not to select the displayed operation mode by looking at the displayed operation mode, expected operation end time Te, and a guideline for the electricity bill. In order to view the contents of other operation modes without selecting the operation mode being displayed, the operation mode selection button 72f on the operation panel 72 is pressed. In step S9, the control circuit 71 checks whether or not the operation mode selection button 72f has been pressed. If so, the process proceeds to step S11.

  In step S11, the expected operation end time Te for the next operation mode and a guideline for the electricity charge are displayed. The order of the operation modes to be displayed is, for example, the order of operation mode 1, operation mode 2, operation mode 3, operation mode 4, and normal operation mode. If displayed, the process returns to step S8 to reset and restart the software timer. The user determines whether or not to select the operation mode by looking at the estimated operation end time Te corresponding to the displayed new operation mode and the guideline of the electricity bill. Through such repetition, the user finally determines the operation mode he / she likes on the spot.

  When the user determines the operation mode, the user leaves the display with the contents of the operation mode displayed on the display device 72b. If the operation mode selection button 72f is not turned on in step S9, the control circuit 71 proceeds to step S10 and checks whether the time measured by the software timer exceeds a predetermined value TX. If not, the process returns to step S9.

  If the user leaves with the determined operation mode displayed, the time measured by the software timer exceeds the predetermined value TX in step S10. When the measured time exceeds the predetermined value TX, the control circuit 71 determines that the operation mode being displayed is finally determined.

  If the operation mode is determined in this way, the process proceeds to step S12. Thereafter, the system waits until the operation start time Tf corresponding to the determined operation mode, and starts the operation at that time (enters the water supply process). If the operation mode 4 has been determined, the operation is started when the amount of generated power received via the communication device 75 becomes equal to or greater than a predetermined value.

  Thus, in the fully automatic washing / drying machine 1 of the present embodiment, the operation end time and the standard of the electric charge are displayed for the five operation modes classified according to the use level of the electric power whose unit price is low. Therefore, the user can select an optimum operation mode according to the place, considering the degree of emphasis on his / her electricity bill and life rhythm (action schedule). As a result, it is possible to save electricity charges and to keep a life rhythm (action schedule).
