Description

  The present invention relates to a washing machine capable of reducing a power charge by using an hourly power charge system.

  In Japan, the hourly power rate system has been introduced. In other words, the electricity charge for general household light lines is cheaper at night (11:00 pm to 7:00 am, depending on the region), so that power consumption shifts from daytime to nighttime, and power demand is leveled. Yes. There has been proposed a washing machine having a function of effectively reducing such a time-based power rate system to reduce the power rate. Examples thereof can be seen in Patent Documents 1 and 2.

  In the washing machine described in Patent Document 1, when the discount of the power charge is desired, if the operation period set by the period setting unit is not in the discount time zone set in the time setting unit, the operation period is set. Correct to be within the discount time zone.

  In the washing machine described in Patent Document 2, the priority time zone can be set by the priority time key, and after pressing the priority time key at a time other than the priority time zone, pressing the start key starts washing. The time is shifted to the beginning of the priority time zone. By setting a power rate discount time zone as the priority time zone, it is possible to save on electricity charges.

There are various other approaches to reducing the electricity charges used by washing machines. The washing machine described in Patent Document 3 tries to reduce power consumption by avoiding useless display operation. In order to realize this, a human detection means for detecting the presence of a person in the vicinity is provided, and the display device is operated only when it is determined that there is a person in the vicinity, and when it is determined that there is no person in the vicinity, the display device Is completely stopped to eliminate the waste of power consumption for display even when no one is watching.
Japanese Patent No. 2845697 (pages 3 to 6, FIGS. 1 to 5) Japanese Patent No. 2781486 (pages 2 to 3, FIGS. 1 to 4) Japanese Patent Laid-Open No. 5-42293 (page 2 to page 3, FIGS. 1 to 4)

  When washing is done during the nighttime electricity rate discount hours, we would like to reduce the electricity used for display in order to make the purpose of saving electricity rates even more thorough. For this purpose, the application of the technique disclosed in Patent Document 3 can be considered, but the operation of detecting and displaying the presence of a person does not necessarily match with washing in the nighttime electricity rate discount period. This is because the electricity charge discount time zone is late at night, and users often make reservations in the hope that the washing process will be completed while sleeping, and there are many cases where the display is not in mind. In such cases, it is often felt that the display glows every time you pass the washing machine, such as folding while standing in your hand. It can be.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a washing machine capable of pursuing a reduction in power charges in terms of both the use of the hourly power charge system and the manner of displaying the washing operation. There is.

  (1) To achieve the above object, the washing machine of the present invention is provided with a key input unit for various inputs, a clock unit, and a display unit for the control device that controls the operation of the washing machine. The apparatus is characterized in that the number of displays appearing on the display unit is reduced as compared with that during normal operation when the apparatus is operating during a power rate discount time zone.

  According to this configuration, when the washing machine is operated during the power charge discount time period, less power is used for display. As a result, the main purpose of saving electricity charges can be maintained. Although it is a problem that the reduction in the number of displays adversely affects usability, many users are sleeping and the effect is small.

  (2) Further, according to the present invention, in the washing machine having the above-described configuration, when the control device is operating during a power rate discount time zone, the display unit displays the normal operation state according to the user's selection. It is characterized by having a function to perform.

  According to this configuration, since the number of displays can be the same as that during normal operation, it is convenient for a user who is active in the same way as daytime even at midnight.

  (3) Further, the present invention is characterized in that in the washing machine configured as described above, the selection is performed by multiple input using different keys of the key input unit.

  According to this configuration, since the display can be switched with the existing key, the manufacturing cost can be reduced to the extent that it is not necessary to newly install the key.

  (4) Further, in the washing machine having the above-described configuration, when a specific operation is performed at the key input unit when displaying a power rate discount time zone, the display is switched to a display during normal operation for a certain period of time. It is said.

  According to this configuration, it is possible to call a normal display by a key operation and confirm the driving situation even when displaying a power rate discount time zone.

  (5) Further, the present invention is characterized in that in the washing machine having the above-described configuration, a plurality of keys that enable the specific operation exist.

  According to this configuration, since there are not only one key for calling a normal display but a plurality of keys, there are few cases where a normal display cannot be called due to a wrong key, and it is easy to use.

  (6) Further, according to the present invention, in the washing machine having the above-described configuration, a lid lock device that locks the lid of the laundry input port in a closed state is provided, and the control device displays a power rate discount time zone. In all steps, the lid is locked by the lid locking device.

  If the washing machine is operating with a small number of displays during the electricity rate discount period, it may be misunderstood that the washing machine is not moving and the lid may be opened. It is dangerous to do such a thing, and if a new laundry is thrown in, the washing sequence will be out of order. If it is assumed that the lid does not open when displaying the power rate discount time zone, such a situation will not occur.

  According to the present invention, when the washing machine is operated during the power charge discount time period, the number of displays is reduced. Therefore, in addition to the discount charge, the power used for display is reduced, so that Electricity charges can be saved.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is an external perspective view of the washing machine, and FIG. 2 is a vertical sectional view thereof. The washing machine 1 has a drying function and has a box-shaped main body 10. Inside the main body 10, a water tank 20 and a drum 30 that accommodates laundry that is to be washed and also to be dried are disposed. Both the water tub 20 and the drum 30 are cylindrical, and each has laundry input ports 21 and 31 on one end face.

  A shaft 32 protrudes outward from the center of the bottom of the drum 30. The shaft 30 is supported by a bearing 22 provided at the center of the bottom of the water tank 20 so that the drum 30 and the water tank 20 are arranged concentrically with the drum 30 inside and the water tank 20 outside.

  The water tank 20 and the drum 30 are supported in the main body 10 so that the axis is horizontal or slightly inclined by a suspension mechanism (not shown). In this embodiment, the axes of the water tank 20 and the drum 30 are inclined at an angle θ (for example, 15 °) with respect to the horizontal plane, and the laundry input ports 21 and 31 are slightly raised. This is to make it easy to see the inside of the drum 30 and to easily put in and out the laundry.

  As described above, the rotation axis of the water tank 20 and the drum 30 intersects the horizontal line, and the intersection angle θ is assumed to be in the range of 0 ° to 30 °, but the angle range is not particularly limited.

  An opening 11 is provided on the front-side outer wall of the main body 10 so as to face the laundry input ports 21 and 31. A laterally open lid 12 is provided on the front surface of the opening 11. The lid 12 can be locked in a closed state by a lid locking device (a mechanism is not shown) provided in the main body 10.

  A door packing 13 made of a soft synthetic resin or rubber connects the opening 11 and the laundry input port 21. The door packing 13 prevents the splash of water generated in the drum 30, the water when the wet laundry is taken in and out, or the overflow from the laundry input port 21 from getting wet inside the main body 10.

  An annular lip 14 is integrally formed on the inner peripheral surface of the door packing 13, which is in close contact with the outer periphery of the protrusion 15 provided on the inner surface of the lid 12, and water is supplied from the gap between the door packing 13 and the lid 12. Prevent leakage. The protrusion 15 plays a role of preventing the laundry in the drum 30 from protruding from the laundry insertion port 21. The protrusion 15 may be formed of a transparent material so that the inside of the drum 30 can be seen through.

  A number of dewatering holes 33 are formed in the peripheral wall of the drum 30. Water goes back and forth between the drum 30 and the water tank 20 through the dewatering hole 33. A plurality of baffles 34 are provided at predetermined intervals on the inner peripheral surface of the drum 30. The baffle 34 catches and lifts the laundry with the rotation of the drum 30 and drops it from above.

  A balance weight (balancer) 35 is attached to the outer surface of the drum 30 and the laundry input port 31. FIG. 2 shows only the annular balance weight 35 attached to the laundry input port 31, and the balance weight attached to the outer surface of the drum 30 is not shown. The balance weight 35 suppresses vibration generated when the drum 30 rotates at a high speed.

  A motor 40 is attached to the bottom outer surface of the water tank 20. The motor 40 is of a direct drive type, and the shaft 32 of the drum 30 is connected and fixed to the rotor. The bearing 22 is attached to the housing of the motor 40 and is a part of the components of the motor 40.

  A water supply valve 50 that opens and closes electromagnetically is disposed in a space above the water tank 20. A water supply hose 51 for supplying tap water such as tap water is connected to the water supply valve 50. The water supply valve 50 is of a triple type, has one input port and three output ports, and can supply and stop water independently for each output port.

  Of the three output ports of the water supply valve 50, the first and second ports are used to supply water to the drum 30 through a water supply nozzle 52 provided at a location facing the laundry input port 31. The first output port is connected to the water supply nozzle 52 via a detergent charging box (not shown). The second output port is connected to the water supply nozzle 52 via a finishing agent input box (not shown). The third output port is used to supply dehumidifying water during the drying operation, and is connected to the dehumidifying spray nozzle 53. The dehumidifying spray nozzle 53 will be described later.

  A drain outlet 23 is provided at the lowest point of the water tank 20, and one end of the drain pipe 60 is connected thereto. The other end of the drain pipe 60 is connected to the filter casing 61. A lint filter 62 is inserted into the filter casing 61. The lint filter 62 is formed of a synthetic resin net or cloth and collects lint in the water. One end of the filter casing 61 is closed by a detachable cap 63, and the lint filter 62 can be cleaned or replaced by removing the cap 63.

  A drain pipe 64 is connected to the filter casing 61, and the waste water that has passed through the lint filter 62 is discharged out of the main body 10. The drain pipe 64 is provided with a drain pump 65.

  The drain pipe 64 is provided with a circulation pump 66 at a location between the lint filter 62 and the drain pump 65. The circulation pump 66 functions to return the water that has passed through the lint filter 62 to the water supply nozzle 53 through the return pipe 67.

  The drain pump 65 is also used as a valve and does not allow water to pass when the operation is stopped. On the other hand, the circulation pump 66 does not have a valve function, and water flows freely downstream unless it is operated.

  The filter casing 61 is provided with an air trap 61a. A water level sensor 69 is provided at the upper end of the pressure guiding pipe 68 led out from the air trap 61a. The water level sensor 69 moves the magnetic body in the coil in accordance with the pressure change in the air trap 61a, detects the resulting inductance change of the coil as a change in the oscillation frequency, and reads the water level from the change in the oscillation frequency. is there. What is read here is the water level in the aquarium 20.

  The laundry that has undergone washing, rinsing, and dehydration is dried in the drum 30. The inside of the drum 30 and the water tank 20 surrounding the drum 30 is a sealed drying chamber 70. That is, the laundry is dried not by air taken from outside the washing machine 1 but by air circulating inside the washing machine 1.

  In order to enable the above-described circulation drying, a circulation duct 71 is formed outside the water tank 20. One end of the circulation duct 71 is connected to the vicinity of the drain outlet 23 of the water tank 20, and the other end is connected to the upper part of the door packing 13. In the middle of the circulation duct 71, a blower 72 and a heater 73 which is a heating means for drying air are provided. The blower 72 functions to suck the air in the sealed drying chamber 70 from the bottom of the water tank 20 and return the sucked air from the top of the door packing 13 to the sealed drying chamber 70. The heater 73 is downstream of the blower 72 and serves to heat the air blown into the sealed drying chamber 70.

  The air flowing through the circulation duct 71 is dehumidified by the dehumidifying means. In the present embodiment, the dehumidifying spray nozzle 53 constitutes a dehumidifying means. The circulation duct 71 rises from the bottom of the water tank 20 and has a flow passage cross-sectional area extending around a bending point where the direction of the circulation duct 71 changes toward the door packing 13. A spray nozzle 53 for dehumidification is installed in the cooling chamber 74.

  The dehumidifying spray nozzle 53 sprays water into the cooling chamber 74 as fine water droplets. The size of the water droplet is set to such an extent that it falls by gravity without flowing into the blower 72 and flows into the water tank 20.

  An operation panel 100 is provided on the front upper surface of the main body 10. The operation panel 100 includes a display unit and a key input unit, details of which will be described later.

  A control device 80 is disposed inside the main body 10 in the vicinity of the operation panel 100. FIG. 3 shows the configuration of the control device 80. A main component of the control device 80 is a microcomputer 81. The microcomputer 81 includes a RAM 83, a ROM 84, and an input / output unit 85 in addition to a central processing unit 82 having a control unit and a calculation unit. The central processing unit 82 includes a count unit 86 and a timer 87. A power supply circuit 88 and a reset circuit 89 are connected to the microcomputer 81. The power supply circuit 88 converts the voltage of the commercial power supply into a voltage suitable for each circuit and supplies it.

  The microcomputer 81 performs various controls according to programs stored in the ROM 84. The counting unit 86 counts operation time and the like, and the counted time and the like are temporarily stored in the RAM 83. The reset circuit 89 initializes the microcomputer 101.

  The following elements are connected to the input / output unit 85. That is, there are a time counting circuit 90, a nonvolatile memory 91 constituting a storage means, a key input unit 92, a state detection circuit 93, a load driving circuit 94, a display unit 101, and a buzzer 103.

  The time counting circuit 90 measures time as a clock. A battery is mounted on the time counting circuit 90, and time can be measured even when power is not supplied from the light line. The non-volatile memory 91 stores data such as operation conditions, time, and a power rate discount time zone. The state detection circuit 93 includes sensors such as the detection means 36 and the water level sensor 69, and a circuit that converts signals from these sensors into digital signals. In the present specification, hereinafter, the power rate discount time zone is simply referred to as “discount time zone”.

  The load driving circuit 94 is connected to the next load. That is, the motor 40, the water supply valve 50, the drainage pump 65, the circulation pump 66, the blower 72, the heater 73, and the lid lock device 16.

  The control device 80 notifies the user that an abnormality has occurred by using notification means. The buzzer 103 disposed in the control device 80 constitutes the notification means. The buzzer 103 rings when a key operation is performed or at the end of washing.

  Signals input from the key input unit 92 and the state detection circuit 93 are processed by the microcomputer 81 in accordance with a program stored in the ROM 84. Based on the processing result, the microcomputer 81 outputs signals to the load drive circuit 94, the display unit 101, and the buzzer 103, and executes a series of steps in the washing machine 1.

  FIG. 4 shows a layout of the operation panel 100. In the operation panel 100, the upper left part is the display unit 101, and the other part is the key input unit 92.

  The display unit 101 is provided with the following function-specific display units. That is, the water level display unit 111, the progress display unit 112, the numerical value display unit 113, the “remaining” display unit 114, the midnight power display unit 115, and the course display unit 116.

  The water level display unit 111 displays whether the set water level is one of three levels of “high”, “medium”, and “low”. The progress display unit 112 displays in which step of the washing machine 1 each of the washing steps (“washing”, “rinsing”, “dehydration”, “drying”). The numerical value display unit 113 displays numerical data such as time, process setting time, and remaining time of the process. The “remaining” display unit 114 displays that the numerical value displayed on the numerical value display unit 113 is the remaining time of the process. The late-night power display unit 115 displays that the washing machine 1 is set to the late-night power mode. The course display unit 116 displays which of four types of driving courses (“Standard”, “Speed”, “Blanket”, “Ganko”) is selected. An LED or a liquid crystal panel is used as a display element of each display unit.

  Membrane switch type input keys are arranged in the key input section 92 as follows. First, at the right end of the operation panel 100, a power key 120 and a start key 121 are arranged vertically. On the left side of the start key 121, various setting keys, that is, a water level key 122, a wash key 123, a rinse key 124, a dewatering key 125, a drying key 126, a course key 127, and a midnight power key 128 are arranged in a horizontal row. On the left side of the power key 120, a reservation key 130 and an “hour” key 131 and a “minute” key 132 for setting the time are arranged.

  The power key 120 is used to turn on / off the power. The start key 121 is used to start or temporarily stop the operation of the washing machine 1. The water level key 122 is used to select the water level in the water tank 20. The washing key 123 is used to set the operation details of the washing process. The rinsing key 124 is used to set the operation content of the rinsing process. The dehydration key 125 is used to select the operation content of the dehydration process. The drying key 126 is used to select the operation content of the drying process. The Kosky 127 is used to select a driving course according to the type of laundry and the degree of dirt. The late-night power key 128 is used to set a course for driving in a discount time zone.

  The reservation key 130 is used to set a reserved operation by a timer. The “hour” key 131 and the “minute” key 132 are used to set “hour” and “minute” when setting the time and the discount time zone, and input a numerical value other than “hour” and “minute”. It is also used to do.

  Next, the operation of the washing machine 1 will be described. First, the lid 12 is opened and the laundry is put into the drum 30. A detergent is put in a detergent charging box (not shown). If necessary, the finishing agent is put in a finishing agent charging box (not shown).

  After preparing preparations for the detergent, the lid 12 is closed and the operation panel 100 is operated. If the power key 120 is set to “ON” and the start key 121 is pressed, the operation of the washing machine 1 starts. The operation of the washing machine 1 is a standard operation mode that has been set in advance (for laundry other than special laundry such as blankets and woolen products, the amount, fabric quality, water level, etc. are automatically judged, from washing to dehydration. However, by operating various input keys before pressing the start key 121, it is possible to reset to any mode other than the standard operation mode.

  In response to the signal from the start key 121, the microcomputer 81 sends a signal to the load driving circuit 94 to start driving the load. First, water is supplied until the water level sensor 69 detects that the water in the water tank 20 has reached a predetermined water level. At this time, water is supplied using the first output port of the water supply valve 50, and the water is poured into the drum 30 from the water supply nozzle 52 while dissolving the detergent in the detergent charging box. At this time, the drain pump 65 is in an operation stop state, and the drain pipe 64 is closed. When the water level sensor 69 detects the set water level, the water supply valve 50 is closed. And the washing process is started.

  The first is the “familiar tumbling” stage, in which the drum 30 rotates at a low speed. The laundry is lifted from the water at a slow pace and falls back into the water. The purpose of “familiarizing tumbling” is to allow the laundry to sufficiently absorb water and to release air trapped in various parts of the laundry.

  When the “fatigue tumbling” stage is completed, the drum 30 moves to the “wash tumbling” stage. The drum 30 rotates at a speed higher than that in the “familiar tumbling”, and the laundry is lifted and dropped. Due to the impact at the time of dropping, a jet of water in which the detergent is dissolved is generated between the fibers of the laundry, and the laundry is washed.

  During the “wash tumbling”, the circulation pump 66 is operated. As a result, the water in the water tank 20 circulates along the path of the drain pipe 60 → the lint filter 62 → the circulation pump 66 → the return pipe 67 → the water supply nozzle 52, and the lint in the water is captured by the lint filter 62. The circulation pump 66 is similarly operated in the rinsing process.

  After the “wash tumbling” stage is completed, the process proceeds to the “balance process”. In the “balance process”, the drum 30 rotates gently. If the drum 30 rotates slowly, the laundry falls off the drum 30 at a lower position before being lifted to a higher position. For this reason, the laundry does not stick to the inner wall of the drum 30 as if it was dropped from a high position, but rather feels like rolling on the inner wall of the drum 30, and the laundry is relatively soft. And overlap. In this state, when the drum 30 starts high-speed dehydration rotation, the laundry is easily dispersed in all directions. That is, it is easy to balance. For this reason, the drum 30 is gently rotated to loosen the laundry and prepare for dehydration rotation.

  After the washing process, the process proceeds to a rinsing process through a dehydration process. In the dehydration process, the circulation pump 66 stops operation, and the drain pump 65 starts operation. When the drain pump 65 starts operation, the water in the water tank 20 is drained outside the machine through the drain pipe 64.

  When a predetermined amount of time has passed and most of the water has drained from the laundry, the drum 30 starts rotating at a relatively low speed. Water contained in the laundry is shaken off by centrifugal force and drained out of the water tank 20 through the drain port 23. After low-speed dehydration, move to high-speed dehydration and thoroughly shake off water. Then the drum 30 stops. The drainage pump 65 is also stopped, and the system for preparing the rinsing water in the water tank 20 is prepared.

  Rinsing water is supplied to the laundry after dehydration. In a normal case, the water supply valve 50 supplies water through the first output port. When the water level in the water tank 20 reaches the set water level, the water supply is stopped and the rinsing process is started.

  First, as in the washing step, there is a “familiar tumbling” stage, and then the “rinse tumbling” stage. The drum 30 lifts and drops the laundry as it passes through the water. As a result, the laundry is rinsed.

  After the “rinse tumbling” stage is completed, the process proceeds to the dehydration process through the “balance process” as in the washing process. The rinsing process is repeated a set number of times.

  When finishing the laundry with the finishing agent, the second output port of the water supply valve 50 is opened at an appropriate timing, and the finishing agent in the finishing agent charging box is poured into the rinsing water.

  In the above description, it is assumed that “rinse rinsing” is performed in which the rinsing water is stored in the water tank 20, but the rinsing is always performed by refilling with fresh water, or the shower in which water is poured into the laundry. Rinsing may be performed.

  After the final rinsing process and the subsequent dehydration process are completed, the process proceeds to the drying process. In the drying process, the blower 72 and the heater 73 are energized while rotating the drum 30 at a low speed. The blower 72 forms a circulating airflow that circulates through the sealed drying chamber 70 and the circulation duct 71, and the heater 73 heats the circulating airflow. The laundry to be tumbled is heated and exposed to a circulating air current that has become warm air, and moisture is taken away.

  The control device 80 monitors the temperature and humidity in the hermetic drying chamber 70 using a temperature sensor and a humidity sensor (not shown), and opens the third output port of the water supply valve 50 to supply water to the dehumidifying spray nozzle 53 at an appropriate timing. The supplied dehumidifying spray nozzle 53 generates spray of dehumidified water. The spray of dehumidified water is constituted by relatively large water droplets as described above, and the water droplets fall without being blown toward the blower 72 by the circulating airflow. When the circulating airflow comes into contact with the falling water, the temperature of the circulating airflow decreases, and moisture in the circulating airflow condenses. The condensed moisture is integrated with the dehumidified water and flows down the circulation duct 71 and enters the water tank 20. And it drains from the drain 23.

  The drying process is continued until a predetermined time has elapsed or until the humidity sensor detects that the humidity of the circulating airflow has decreased to a predetermined value. When the drying process ends, the whole process is finished, and the washing machine 1 stops.

  Next, a method for setting the time on the operation panel 100 will be described with reference to FIGS. 5 and 6 in addition to FIG. 5 and 6 are explanatory diagrams schematically showing a situation in which the display of the numerical value display portion 113 changes.

  The state where the power is supplied to the control device 80 but the power key 120 is “OFF” is the “power key input waiting state”. When the power key 120 is pressed here, the “power key input waiting state” is changed to the “operation setting ready state”, and the system is ready to accept the input of keys other than the power key 120.

  When setting the time, the power key 120 and the reservation key 130 are pressed simultaneously in the “power key input waiting state”. Then, the “time setting state” is entered. In the initial display, as shown in FIG. 5, the portion on the left side of the “colon” in the numerical display portion 113, that is, the “hour” side blinks. In FIG. 5, a blinking state is expressed by a number consisting of a set of points, and a continuous display state is expressed by a blacked-out number.

  When the “hour” key 131 is pressed, the blinking number is incremented by one. When the desired number appears, the finger is released from the “hour” key 131 and the start key 121 is pressed.

  When “hour” is determined, the “minute” side blinks as shown in FIG. Next, after selecting a desired number using the “minute” key 132, the “minute” is determined using the start key 121.

  After the time is determined as “hour” and “minute”, the time counting circuit 90 starts measuring the time from the determined time. When the power key 120 is pressed thereafter, the “operation setting ready state” returns to the “power key input waiting state”. Set the time, set the discount time zone, and enter other values as described above.

  As described above, when the power key 120 and the reservation key 130 are pressed simultaneously in the “power key input waiting state”, the “time setting state” can be displayed. Thus, since the existing key is used for switching the display, it is not necessary to newly install a dedicated key, and the manufacturing cost can be suppressed.

  Various settings can be made in the washing machine 1 by key input. Hereinafter, an operation when various settings are performed or a procedure when performing the settings will be described with reference to FIGS.

  FIG. 7 shows an operation flow when the washing machine 1 is operated in a time zone other than the discount time zone and the discount time zone. This flow corresponds to the configuration of claim 1.

  In this specification, the setting for driving in a time zone other than the discount time zone is referred to as “normal operation mode”, and the setting for driving in the discount time zone is referred to as “midnight power mode”. The operation in the normal operation mode is referred to as “normal operation”, and the operation in the midnight power mode is referred to as “midnight operation”.

  First, in step # 201, a “power key input waiting state” is entered. In the next step # 202, it is checked whether or not the midnight power mode is set in the washing machine 1. If the midnight power mode is set, the process proceeds to step # 203, and if not, the process proceeds to step # 211.

  First, the case where the process proceeds to step # 211 will be described. When the start key 121 is pressed in step # 211, the process proceeds to step # 212. And normal operation starts. Then, the process proceeds to step # 213, and the display in the normal operation mode is lit on the display unit 101.

  FIG. 8 shows a display state in the normal operation mode. At this time, display is performed using all of the water level display unit 111, the progress display unit 112, the numerical display unit 113, the “remaining” display unit 114, and the course display unit 116 except for the midnight power display unit 115. In the example of FIG. 8, the water level “high” is displayed on the water level display unit 111, the current process is displayed on the progress display unit 112, and the “standard” course is displayed on the course display unit 116. In the numerical display 113, the remaining time of the process is displayed in response to the “remaining” display 114 being in the display state. In the remaining time display, the left side of the colon represents “minute” and the right side of the colon represents “second”. The display mode may be continuous lighting or light flashing.

  When the process proceeds to step # 203, the midnight power display unit 115 is turned on. When the start key 121 is pressed in step # 204, the process proceeds to step # 205. Then, the current time measured by the time counting circuit 90 and the discount time zone data stored in the nonvolatile memory 91 are collated, and it is determined whether or not the current time is in the discount time zone. If it is not yet in the discount time zone, the process proceeds to step # 206, and the operation is waited until the discount time zone comes. If it is in the discount time zone, the process proceeds to step # 207, and midnight driving starts. Then, the process proceeds to step # 208, and the display in the midnight power mode is lit on the display unit 101.

  FIG. 9 shows the display status in the midnight power mode. At this time, only the midnight power display unit 115 is lit, and the remaining water level display unit 111, the progress display unit 112, the numerical display unit 113, the “remaining” display unit 114, and the course display unit 116 are all turned off. It is in.

  Thus, when the washing machine 1 is operated during the discount time period, only the midnight power display unit 115 is turned on, and the remaining display units are turned off, so that the power used for display is reduced. The main purpose of saving electricity charges can be maintained. In order to further reduce the power consumption, all the lights including the midnight power display unit 115 may be turned off.

  FIG. 10 shows an operation flow when displaying in the normal operation mode even during midnight operation. This flow corresponds to the configuration of claim 2.

  Step # 221 is step # 201 of the flow of FIG. 7, step # 222 is step # 202, step # 223 is step # 203, step # 241 is step # 211, step # 242 is step # 212, Step # 243 corresponds to step # 213, and description of the contents of these steps is omitted. The difference from the flow of FIG. 7 comes from step # 224. In step # 224, it is checked whether or not the course key 127 and the water level key 122 are simultaneously pressed. If they are simultaneously pressed, the process proceeds to step # 225 and then proceeds to step # 226. If not simultaneously pressed, the process proceeds directly to step # 226.

  When the process proceeds to step # 225, the setting is switched to display the normal operation mode even during midnight operation. Then, the process proceeds to step # 226.

  If the start key 121 is pressed in step # 226, the process proceeds to step # 227. Then, the current time measured by the time counting circuit 90 and the discount time zone data stored in the nonvolatile memory 91 are collated, and it is determined whether or not the current time is in the discount time zone. If it is not yet in the discount time zone, the process proceeds to step # 228, and the operation is waited until the discount time zone comes. If it is in the discount time zone, the process proceeds to step # 229, and the operation at midnight starts. Then, the process proceeds to step # 230.

  In step # 230, it is checked whether or not the setting has been changed so that the display is in the normal operation mode even during midnight operation. If it has not switched, it will progress to step # 231 and will be the display at the time of midnight power mode. If it has switched, it will progress to step # 232 and the display at the time of normal operation mode will light.

  Thus, since the display mode at the time of midnight driving can be made the same as that at the time of normal driving, it is convenient for a user who is active in the same way as daytime even at midnight.

  FIG. 11 shows an operation flow when displaying in the normal operation mode during display in the midnight power mode. This flow corresponds to the configuration of claim 4.

  In step # 251, display in the midnight power mode is performed. When a key other than the power key 120 and the start key 121 is pressed in step # 252, the process proceeds to step # 253, and the display is switched to the normal operation mode. In step # 254, the elapsed time after switching to the display in the normal operation mode is measured by the counting unit 86. When a predetermined time, for example, 5 seconds elapses, the process proceeds to step # 255. Then, the display returns to the display in the midnight power mode.

  As described above, even when the display is in the midnight power mode, it is convenient because the display in the normal operation mode can be called by a key operation to check the operation status. In addition, the display in the normal operation mode can be called by all keys other than the power key 120 and the start key 121 instead of a single key. Therefore, the display in the normal operation mode cannot be called because the key is wrong. There are few, and it is convenient.

  FIG. 12 depicts a flow showing the relationship between display selection and the operation of the lid lock device 16. This flow corresponds to the configuration of claim 6.

  When the midnight operation starts in step # 261, it is checked in step # 262 whether or not the setting for performing the display in the normal operation mode is made. If the setting has been made, the process proceeds to step # 265 to display the normal operation mode. Then, the process proceeds to step # 266. In step # 266, the lid locking device 16 appropriately performs an operation of locking or not locking the lid 12 according to the process at that time.

If the setting for performing the display in the normal operation mode is not made, the process proceeds to step # 263, and the display in the midnight power mode is performed. Then, the process proceeds to step # 264. Step # 2
When proceeding to 64, the lid locking device 16 locks the lid 12 in all steps.

  When the washing machine 1 is operating with the display in the midnight power mode, the number of displays is small, so that the washing machine 1 may be misunderstood and the lid 12 may be opened. Doing so is dangerous, and even if new laundry is thrown in, the washing sequence will be out of order. If the lid lock device 16 is always operated when the display is in the midnight power mode and the lid 12 is not opened, such a situation will not occur.

    Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

    The present invention can be widely used in washing machines that intend to utilize the hourly power rate system.
