The input setting means 24 is input by the user, gives instructions to the control means 22, and the display means 25 performs a display operation according to the output of the control means 22.

  The water level detection means 26 detects the water level of the washing and dewatering tub 1. The rotation speed detection means 27 outputs a pulse corresponding to the rotation speed of the motor 4, and the output of the rotation speed detection means 27 is input to the control means 22, and the control means 22 performs washing in the washing and dewatering tub 1. It has a function to detect the amount of objects.

  The storage means 28 stores data necessary for sequentially controlling a series of strokes by the control means 22. The nonvolatile memory 29 retains the stored contents even when the power is turned off. The nonvolatile memory 29 adds the type of liquid detergent set by the input setting means 24 and the amount of detergent to be put into the washing / dehydrating tub. The weight loss is memorized. The buzzer 30 sounds a buzzer sound with a signal from the control means 22. Reference numeral 31 denotes a commercial power source.

  As shown in FIG. 2, the input setting means 24 includes a water level setting switch 24a, a detergent charging setting switch 24b, a washing time setting switch 24c, a rinse count setting switch 24d, a dehydration time setting switch 24e, a course setting switch 24f, a start / temporary setting. The switch includes a stop switch 24g, a power-on switch 24h, a power-off switch 24i, and the like.

  The display means 25 is composed of a light emitting body such as a light emitting diode (hereinafter referred to as “lamp”), and includes a water level display section 25a, a detergent input display section 25b, a washing time display section 25c, a rinse count display section 25d, and a dehydration time display section 25e. The course display unit 25f is used.

  The detergent charging setting switch 24b can be set in the detergent tank 16 and set two types of detergents A and B as the types of liquid detergents 15 to be loaded into the washing and dehydrating tank 1. The setting amount can be set to be “large”, and the set state is displayed on the detergent charging display portion 25 b and is further stored in the nonvolatile memory 29.

  Here, “detergent A” can obtain a predetermined cleaning performance by adding 15 ml of liquid detergent to, for example, 30 liters of water, and “detergent B” can be obtained of, for example, 30 liters of water. A predetermined cleaning performance can be obtained by adding 20 ml of liquid detergent. In addition, when “large” is set, each liquid detergent can be increased to 1.25 times the amount of detergent when “large” is not set.

  Next, in the initial setting of the detergent input, the “detergent A” is set to be input. When the power is turned on by the power-on switch 24h, as shown in FIG. Only the lamp b1 is lit. In this state, when the detergent insertion setting switch 24b is pressed, “detergent B” is set to be introduced, and only the lamp b2 of the detergent introduction display section 25b is lit as shown in FIG. In this state, when the detergent loading setting switch 24b is further pressed, “detergent A” is set to be “larger”, and as shown in FIG. 3C, the lamps b1 and b3 of the detergent loading display section 25b are set. Both lights up.

  In this state, when the detergent insertion setting switch 24b is further pressed, “detergent B” is set to be “larger”, and as shown in FIG. 3D, the lamps b2 and b3 of the detergent introduction display section 25b are set. Both lights up. In this state, if the detergent insertion setting switch 24b is further pressed, the automatic detergent insertion is set not to be performed, and as shown in FIG. 3 (e), all the lamps of the detergent insertion display portion 25b are turned off. When the detergent setting switch 24b is pressed in this state, the state returns to the state shown in FIG.

  In this way, by setting the type of liquid detergent 15 and the amount of detergent to be added into the washing and dewatering tub 1 by the detergent insertion setting switch 24b and turning on the start / pause switch 24g, the nonvolatile memory 29 is loaded. The set contents are memorized.

  The operation in the above configuration will be described. When washing with "Detergent A", put "Detergent A" into the detergent tank 16 as the liquid detergent 15, put the laundry into the washing and dehydrating tank 1, and turn on the power with the power on switch 24h Then, since the initial setting of detergent introduction is set to insert “detergent A”, only the lamp b1 of the detergent introduction display section 25b is lit as shown in FIG.

  In this state, for example, the “automatic” course is set by the course setting switch 24f, or the washing time, the number of times of rinsing, and the dehydration time are individually set by the washing time setting switch 24c, the rinse number setting switch 24d, and the dehydration time setting switch 24e. When the setting is made and the operation is started by turning on the start / pause switch 24g, the setting contents of the detergent input, that is, “detergent A” is stored in the nonvolatile memory 29.

  At the same time, the motor 4 is turned on, the stirring blade 2 is rotated, the stirring blade 2 is rotated for a predetermined time, and the number of pulses detected by the rotational speed detection means 27 during inertial rotation when the motor is turned off is supplied to the control means 22. Input and detect the amount of laundry put into the washing and dewatering tub 1.

  Based on the detected amount of laundry, the control means 22 determines the water level to be supplied into the washing and dewatering tub 1 and displays it on the water level display unit 25a. When the water supply valve 11 is opened and water supply is started, the motor 4 is driven to rotate the washing and dewatering tub 1 almost simultaneously, while the air pump 18 is turned on and the liquid detergent 15 in the detergent tank 16 is turned on. 1 according to the amount of water supplied.

  Here, since the setting is made so that “detergent A” is introduced, “detergent A” is introduced at a ratio of 15 ml to 30 liters of water. The amount of detergent input at this time is controlled by the driving time of the air pump 18. At this time, since the washing and dewatering tub 1 is rotated, the liquid detergent 15 can be dispersed and introduced without being concentrated in one place. When the liquid detergent 15 is introduced and water is supplied to a predetermined water level, the water level detecting means 26 detects it, stops the water supply, performs stirring by the stirring blade 2, and proceeds to a process of removing dirt on the clothes, and then a rinsing process. The dehydration process is performed.

  In the next operation, when power is turned on by the power on switch 24h, “detergent A” is stored in the non-volatile memory 29. Therefore, only the lamp b1 of the detergent insertion display section 25b is lit up. A "can be washed.

  Next, when “detergent A” is used as the liquid detergent 15 and laundry that is heavily soiled is washed, when the power is turned on, the detergent insertion display portion 25b is stored in the nonvolatile memory 29 during the previous operation. Although the contents are displayed, if the detergent setting switch 24b is pressed and “detergent A” is set to “large” so that the quantity is increased by 1.25 times, as shown in FIG. The lamps b1 and b3 of the display unit 25b are turned on. In this state, when a predetermined course is set by the course setting switch 24f and the start / pause switch 24g is turned on to start the operation, the setting contents of the detergent input, that is, the “detergent A” in the non-volatile memory 29 is set to “ Stores the setting to be input to “Large”.

  And the amount of the laundry thrown into the washing and dehydrating tub 1 is detected, and based on the detected amount of laundry, the control means 22 determines the water level to be supplied into the washing and dehydrating tub 1, and the water level indicator 25a. To display. When the water supply valve 11 is opened and water supply is started, the motor 4 is driven to rotate the washing and dewatering tub 1 almost simultaneously, while the air pump 18 is turned on and the liquid detergent 15 in the detergent tank 16 is turned on. The amount of detergent is increased with respect to the amount of water to be fed into 1 and charged.

  In this example, “detergent A” is set to be “large”, so “detergent A” is added in a ratio of 15 ml to 30 liters of water and 1.25 times the amount of detergent. . When the liquid detergent 15 is introduced and water is supplied to a predetermined water level, the water level detecting means 26 detects it, stops the water supply, performs stirring by the stirring blade 2, and proceeds to a process of removing dirt on the clothes, and then a rinsing process. The dehydration process is performed.

  In the next operation, when the power is turned on by the power-on switch 24h, the nonvolatile memory 29 stores the setting for turning "detergent A" into "more", so the lamps b1 and b3 of the detergent insertion display section 25b It is in a lit state, and “detergent A” can be put in “more” and washed.

  Next, when washing using “detergent B” as the liquid detergent 15, “detergent B” is put in the detergent case 16 as the liquid detergent 15, the laundry is put into the washing and dehydrating tub 1, When the power is turned on by the on / off switch 24h, the contents stored in the non-volatile memory 29 during the previous operation are displayed on the detergent on / off display unit 25b. If it sets so, as shown in FIG.3 (b), only the lamp | ramp b2 of the detergent insertion display part 25b will be in the state turned on. In this state, when a predetermined course is set with the course setting switch 24f and the start / pause switch 24g is turned on to start the operation, the setting contents of the detergent input, that is, "detergent B" is input to the nonvolatile memory 29. The settings to be stored are stored.

  In the same manner, the “detergent B” can be turned on for washing, and when the power is turned on by the power-on switch 24h in the next operation, the setting for turning on the “detergent B” is stored in the nonvolatile memory 29. Therefore, only the lamp b2 of the detergent input display section 25b is in a lit state, and the “detergent B” can be input for washing.

  Next, when “detergent B” is used as the liquid detergent 15 and laundry that is heavily soiled is washed, when the power is turned on, the detergent insertion display portion 25b is stored in the nonvolatile memory 29 during the previous operation. Although the contents are displayed, if the detergent setting switch 24b is pressed and “detergent B” is set to “large” so that the quantity is increased by 1.25 times, the detergent is supplied as shown in FIG. The lamps b2 and b3 of the display unit 25b are turned on. In this state, when a predetermined course is set with the course setting switch 24f and the start / pause switch 24g is turned on to start the operation, the setting contents of the detergent input, that is, the "detergent B" is stored in the nonvolatile memory 29 as "detergent B". The setting to be input as “large” is stored.

  In the same manner, the amount of “detergent B” can be increased by 1.25 times and can be washed, and when the power is turned on by the power-on switch 24h during the next operation, the “detergent” is stored in the nonvolatile memory 29. Since “B” is set to “high”, the lamps b2 and b3 of the detergent input display section 25b are lit, and the amount of “detergent B” is increased by 1.25 times. And can be washed.

  By the way, liquid detergents include weak alkaline ones suitable for washing ordinary clothes and others, and neutral ones suitable for washing hair products. When hair products such as feather blankets and sweaters are washed with a neutral detergent, shrinkage may occur. For this reason, in the “blanket” course in the washing course, it is necessary to carry out washing after confirming the type of blanket and the type of liquid detergent.

  In addition, in the “gogogoshi” course, since it is premised on washing clothes with a high degree of dirt from the beginning, it is advantageous to use a large amount of liquid detergent.

  In this way, by changing the control content of the liquid detergent charging according to the washing course when washing, it is possible to prevent problems such as shrinkage and provide a more optimal liquid detergent charging method.

  Next, an example of operations of the detergent input display unit 25b, the course setting switch 24f, and the course display unit 25f will be described with reference to FIG.

  For example, when the power is turned on by the power-on switch 24h, as shown in FIG. 4 (a), only the lamp b1 is lit so that the “detergent A” is turned on as shown in FIG. It is assumed that the lamp f1 is turned on and the “Omakase” course is set. In this state, when the course setting switch 24f is pressed, the lamp f2 of the course display section 25f is turned on as shown in FIG. 4B to change to the “high speed” course, and the detergent insertion display section 25b remains unchanged. The lamp b1 is turned on so that the “detergent A” is inserted. In this state, when the course setting switch 24f is further pressed, the lamp f3 of the course display section 25f is turned on as shown in FIG. 4C, and the course is changed to the "gosh" course, and the detergent insertion display section 25b is set to "detergent A". So that the lamp b1 and the lamp b3 are turned on so as to be put in “more”.

  If the setting switch 24f is further pressed in this state, the lamp f4 of the course display section 25f is turned on as shown in FIG. 4 (d), and the course is changed to the “blanket” course, and the detergent insertion display section 25b is not charged with detergent. The lamps b1, b2, and b3 are all turned off. When the start / pause switch 24g is pressed in the state shown in FIG. 4D, the operation of the “blanket” course is started without automatically supplying the liquid detergent.

  4D, if the user wants to automatically supply the liquid detergent, when the detergent insertion setting switch 24b is pressed in this state, the lamp of the course display section 25f is displayed as shown in FIG. In the “blanket” course in which f4 is lit, the detergent input display unit 25b is in a state where the lamp b1 is lit to input “detergent A”.

  When the start / pause switch 24g is pressed in the state shown in FIG. 4E, the liquid detergent is automatically supplied and the “blanket” course starts.

  As described above, when washing clothes with a lot of dirt, it is set so that a large amount of liquid detergent is automatically added when a “gossip” course is selected as shown in FIG. If there is a possibility that a problem such as shrinkage may occur when washing with a weak alkaline detergent as shown in FIG. 4B, the liquid detergent is not automatically charged when the “blanket” course is selected as shown in FIG. be able to. In addition, when a normal blanket that is not a feather blanket is used, it is better to automatically add the liquid detergent, so the setting can be changed so that the liquid detergent is automatically added as shown in FIGS. 4 (d) to 4 (e). it can.

  In addition, when the automatic charging method of the liquid detergent 15 for each course is set and the washing operation is started by pressing the start / pause switch 24g, the setting information is sent from the control means 22 to the nonvolatile memory 29 and set. Is stored, and at the time of the next washing setting, the detergent input display portion 25b can be displayed according to the stored setting content.

(Embodiment 2)
FIG. 5 is a diagram showing a detergent input display unit, a course setting switch, and a course display unit of the washing machine according to the second embodiment of the present invention. The same parts as those in the above embodiment are denoted by the same reference numerals and the description thereof is omitted.

  For example, when the power is turned on by the power-on switch 24h, as shown in FIG. 5 (a), only the lamp b1 is turned on so that the “detergent A” is turned on as shown in FIG. It is assumed that the lamp f1 is turned on and the “Omakase” course is set. In this state, when the course setting switch 24f is pressed, the lamp f2 of the course display section 25f is turned on as shown in FIG. 5B to change to the “high speed” course, and the detergent insertion display section 25b is not changed. The lamp b1 is turned on so that the “detergent A” is inserted. In this state, when the course setting switch 24f is further pressed, the lamp f3 of the course display section 25f is turned on as shown in FIG. 5C, and the course is changed to the "gosh" course, and the detergent input display section 25b is set to "detergent A". So that the lamp b1 and the lamp b3 are turned on so as to be put in “more”.

  The operation up to this point is the same as in the first embodiment.

  In this state, when the course setting switch 24f is further pressed, the lamp f4 of the course display section 25f is turned on as shown in FIG. 5D to change to the “blank” course, and the liquid detergent 15 is automatically turned on. However, the user is warned of whether or not this is acceptable, and the lamp b1 of the detergent insertion display section 25b is blinked so that the detergent is not charged.

  When a certain time (for example, 10 seconds) has elapsed in the state of FIG. 5D, the detergent input display portion remains in the “blanket” course in which the lamp f4 of the course display portion 25f is lit as shown in FIG. 5E. In 25b, the lamp b1 is turned on so that the liquid detergent 15 is automatically charged.

  This is because, after giving attention to the user, if the user does not change the setting, the setting is confirmed and the setting status is displayed more clearly.

  When the start / pause switch 24g is pushed in the state of FIG. 5D or 5E, the liquid detergent 15 is automatically turned on and the operation of the “blanket” course starts. 5D and 5E, if the user does not want the liquid detergent 15 to be automatically turned on, pressing the detergent setting switch 24b in this state will result in FIG. 5F. In the course display portion 25f, the lamp f4 remains on the “blanket” course, and the detergent input display portion 25b is in a state where the lamps b1 to b3 are turned off so as not to automatically supply the liquid detergent 15. When the start / pause switch 24g is pressed in the state of FIG. 5 (f), the operation of the “blanket” course starts without automatically supplying the liquid detergent 15.

  As described above, when there is a possibility that a problem such as shrinkage may occur when washing with a weak alkaline detergent such as a feather blanket, the liquid detergent 15 is removed when the “blanket” course is selected as shown in FIG. By blinking the lamp to attract the user's attention in order to confirm whether or not automatic charging is allowed, the probability of occurrence of defects such as shrinkage of clothing due to automatic loading of the liquid detergent 15 can be reduced. .

  In addition, when it is a normal blanket that is not a feather blanket, it is better to automatically add the liquid detergent 15, so the setting is changed so that the liquid detergent is automatically added from (d), (f) to (e) in FIG. be able to.

  By the way, blinking the lamp of the display means 25 is a frequently used method. For example, for the purpose of displaying the progress during driving, it is often used in current washing machines to blink the lamp of the washing time display section 25c during washing, or to blink the lamp of the rinse count display section 25d during rinsing. . Since the blinking of the lamp in this case does not call the user's attention, it is a blinking of a slow cycle of about 0.4 seconds for lighting and 0.4 seconds for turning off.

  However, the blinking cycle of the lamp b1 of the detergent insertion display unit 25b in the state of FIG. 5D is for urging the user whether or not the liquid detergent can be automatically charged. Flashing at a cycle faster than usual, such as 0.2 seconds and extinguishing 0.2 seconds, is effective in calling attention.

  In addition, if the buzzer 30 is sounded at the same time as the lamp b1 of the detergent input display section 25b flashes in the state of FIG. 5D, the liquid detergent can be more clearly and surely given to the remote user. You can call attention to whether or not it can be automatically entered.

(Embodiment 3)
FIG. 6 is a diagram showing a detergent input display unit, a course setting switch, and a course display unit of the washing machine according to the third embodiment of the present invention. The same parts as those in the above embodiment are denoted by the same reference numerals and the description thereof is omitted.

  For example, when the power is turned on by the power-on switch 24h, as shown in FIG. 6 (a), only the lamp b1 is lit so that the “detergent A” is turned on as shown in FIG. It is assumed that the lamp f1 is turned on and the “Omakase” course is set. In this state, when the course setting switch 24f is pressed, the lamp f2 of the course display section 25f is turned on as shown in FIG. 6B to change to the “high speed” course, and the detergent input display section 25b is not changed. The lamp b1 is turned on so that the “detergent A” is inserted. In this state, when the course setting switch 24f is further pressed, the lamp f3 of the course display section 25f is turned on as shown in FIG. 6C, and the course is changed to the “gosh” course, and the detergent insertion display section 25b is set to “detergent A”. So that the lamp b1 and the lamp b3 are turned on so as to be put in “more”.

  The operation up to this point is the same as in the first embodiment.

  In this state, when the setting switch 24f is further pressed, the lamp f4 of the course display unit 25f in FIG. 6D is turned on to change to the “blanket” course, and the lamp b1 of the detergent insertion display unit 25b is turned on. The state in which the lamps b1 to b3 of the detergent insertion display unit 25b in FIG. 6E are turned on is alternately repeated. This is to change the “blanket” course, and the liquid detergent 15 is automatically charged, but this is to urge the user to note whether this is okay.

  When a predetermined time (for example, 10 seconds) has passed while the states shown in FIGS. 6D and 6E are alternately repeated, a blanket in which the lamp f4 of the course display section 25f is turned on as shown in FIG. In the course, the detergent input display section 25b is in a state where the lamp b1 is lit to automatically input the liquid detergent 15. This is because, after giving attention to the user, if the user does not change the setting, the setting is confirmed and the setting status is displayed more clearly.

  When the start / pause switch 24g is pushed in the states of FIGS. 6D, 6E, and 6F, the liquid detergent 15 is automatically turned on and the operation of the “blanket” course starts.

  If the user does not want to automatically put the liquid detergent 15 in the states of FIGS. 6D, 6E, and 6F, when the detergent loading setting switch 24b is pressed in this state, FIG. As shown in g), while the “blanket” course in which the lamp f4 of the course display section 25f is lit, the detergent input display section 25b is in a state where all the lamps b1 to b3 are turned off so as not to automatically supply the liquid detergent 15. When the start / pause switch 24g is pushed in the state of FIG. 6G, the liquid detergent 15 is not automatically supplied and the operation of the “blanket” course starts.

  As described above, when there is a possibility that a problem such as shrinkage may occur when washing with a weak alkaline detergent such as a feather blanket, when the “blanket” course is selected as shown in FIGS. 6 (d) and 6 (e). By alternately illuminating the lamps so as to draw attention to the user whether or not the liquid detergent 15 may be automatically charged, the probability that the feather blanket will shrink due to the automatic loading of the liquid detergent 15 is reduced. can do.

  In addition, when a normal blanket that is not a feather blanket is used, it is better to automatically add the liquid detergent, so that the liquid detergent is automatically supplied from (d), (e), (g) to (f) in FIG. Can be changed.

  As in the second embodiment, it is effective to call attention if the cycle of alternately repeating the display of FIGS. 6D and 6E is faster than the normal blinking cycle. If the buzzer 30 is sounded in the states of) and (e), the user can be more surely warned of whether or not the liquid detergent 15 can be automatically introduced.

  As described above, the washing machine according to the present invention is not easy to wash clothes with an inappropriate liquid detergent and is easy to use. The present invention can also be applied to various machines equipped with a washing machine and a device that automatically supplies liquid, powder, granules and the like.
