【００２４】
なお、（表１）で、○印は、吸水ポンプ２７が動作することを示し、×印は、吸水ポンプ２７が動作しないことを示している。
【００２５】
ここで、吸水ポンプ２７をすすぎ行程まで使用するコース設定の場合には、一連の洗濯行程における最後のすすぎは、風呂水を使わずに必ず給水弁２６により制御される水道水で行うようにし、すすぎの最後はきれいな水を使用することで、風呂水などの臭いが仕上がった洗濯物に残るのを防いでいる。（表１）は、コース設定スイッチ３２ｆにより、「お急ぎコース」を設定した場合であり、「お急ぎコース」では、水位を「低水位」以下に設定したときは、すすぎを１回に設定するようにしている。
【００２６】
制御手段３０は、吸水ポンプ設定スイッチ３２ｅにより吸水ポンプ２７の動作モードを設定した後に水位設定スイッチ３２ａにより水位を切り換えた場合には、設定された水位に応じて、吸水ポンプ２７の動作モードを自動的に切り換えて設定し、切り換えた吸水ポンプ２７の動作モードを表示手段３３に表示する構成としている。
【００２７】
上記構成において動作を説明する。電源スイッチ３７の投入時には、標準的な洗濯行程を実行する「標準コース」が設定されている。ここで、スタート／一時停止スイッチ３２ｇを押すと決められた手順で洗濯が自動的に開始する。
【００２８】
今、コース設定スイッチ３２ｆにより、「お急ぎコース」を設定し、吸水ポンプ設定スイッチ３２ｅにより、吸水ポンプ２７を洗いとすすぎ時に吸水ポンプ２７を動作させるモードに設定すると、吸水ポンプ表示部３３ｅの「洗い」、「すすぎ１」が点灯する。ここで、吸水ポンプ２７の動作中は吸水ポンプ表示部３３ｅが点滅し、吸水ポンプ２７の動作行程を表示する。
【００２９】
この状態で、水位設定スイッチ３２ａにより「低水位」に設定すると、「低水位」では、（表１）に示すように、吸水ポンプ２７を動作させないモードであるため、吸水ポンプ２７を自動的に動作しないように切り換えて、吸水ポンプ表示部３３ｅの「洗い」、「すすぎ１」を消灯し、使用者に設定状態を報知する。
【００３０】
「お急ぎコース」では、すすぎを短時間で行うために。洗濯兼脱水槽１２に給水しながらすすぎを行う、いわゆる注水すすぎを行っているが、このとき、洗濯量が多くて高い水位で洗濯をする場合に比べて、洗濯量が少なく低い水位で洗濯をする場合は、洗濯量に対して洗濯兼脱水槽１２に入る水の量が多いため、すすぎ性能がよくなる。
【００３１】
したがって、高水位の場合は２回のすすぎを行うところを、低水位では１回で充分なすすぎ性能を得ることが可能である。そのため、「お急ぎコース」で、低水位以下の水位を設定した場合は、すすぎが１回のみとする。したがって、１回目のすすぎが洗濯コースの最後のすすぎとなるので、吸水ポンプ２７を自動的に動作しないように切り換えて、風呂水を利用せずに水道水ですすぎをすることで、風呂水の臭い移りなどを防ぐことができる。
【００３２】
さらに、吸水ポンプ２７の動作状態を表示手段３３の吸水ポンプ表示部３３ｅにより表示するので、操作および現在設定の状態を確認することができ、吸水ポンプ２７の動作設定の手順に関係なく所定の設定をすることができるため、設定操作が容易になり、誤操作を防止できる。
【００３３】
なお、本実施例では、「お急ぎコース」を設定し、吸水ポンプ２７を洗いとすすぎ時に吸水ポンプ２７を動作させるモードに設定した後、「低水位」に設定したとき、吸水ポンプ２７を動作しないように切り換えているが、これに限定されるものでなく、他のコースを設定し、「低水位」以外に設定したときでも、すすぎ回数が１回になれば、吸水ポンプ２７を自動的に動作しないように切り換えることで、風呂水を利用せずに水道水ですすぎをすることで、風呂水の臭い移りなどを防ぐことができる。
【００３４】
（実施例２）
図１における制御手段３０は、布量判定手段３５による布量判定の結果により、吸水ポンプ２７を動作モードを切り換えるようにしている。他の構成は上記実施例１と同じである。
【００３５】
上記構成において動作を説明すると、布量判定手段３５は、モータ２１を所定時間動作させた直後のパルセーター１１の惰性回転数により、洗濯兼脱水槽１２内の布量を判定する。すなわち、洗濯の開始前にモータ２１を、たとえば０.５秒間導通させ、停止したときのパルセーター１１の惰性回転を進相コンデンサ３６に生ずるパルス数を計数することで、布量を判定する。パルス数が多いと負荷が軽く、布量が少ない。
【００３６】
このとき、定格容量より布量が少ない場合は、布に対する水量が多くなるため、すすぎ性能が向上する。特に、注水すすぎで時間短縮を行う「お急ぎコース」ではその傾向が顕著である。したがって、「お急ぎコース」の場合は、布量が少ないと判定した場合は、すすぎを１回にして、短時間で洗濯が終了するように制御する。すすぎが１回の場合は、前述通り、すすぎ行程での吸水ポンプ２７の使用は不適切なため、たとえ設定していた場合でも自動的に吸水ポンプ動作モードを取り消す。
【００３７】
したがって、布量が少ないと判定した場合は、すすぎを１回にして、吸水ポンプ２７を自動的に動作しないように切り換えて、風呂水を利用せずに水道水ですすぎをすることで、風呂水の臭い移りなどを防ぐことができる。
【００３８】
なお、本実施例では、「お急ぎコース」を設定し、布量が少ないと判定した場合は、吸水ポンプ２７を自動的に動作しないように切り換えているが、これに限定されるものでなく、他のコースを設定したときでも、布量の判定結果により、すすぎ回数が１回になれば、吸水ポンプ２７を自動的に動作しないように切り換えることで、風呂水を利用せずに水道水ですすぎをすることで、風呂水の臭い移りなどを防ぐことができる。
【００３９】
（実施例３）
図１における制御手段３０は、洗い時間設定スイッチ３２ｂ、すすぎ回数設定スイッチ３２ｃ、脱水時間設定スイッチ３２ｄにより、洗い時間、すすぎ回数、脱水時間を個別に設定したとき、吸水ポンプ設定スイッチ３２ｅを押すことで、（表２）に示すように、洗い時に吸水ポンプ２７を動作（風呂水を使用）させるモード、洗いとすすぎ時に吸水ポンプ２７を動作させるモード、吸水ポンプ２７を動作させないモードを切り換えて設定できるようにしている。このとき、設定モードにしたがって、吸水ポンプ表示部３３ｅの「洗い」、「すすぎ１」が点灯する。
【００４０】
【表２】

【００４１】
なお、（表２）で、○印は、吸水ポンプ２７が動作することを示し、×印は、吸水ポンプ２７が動作しないことを示している。
【００４２】
また、制御手段３０は、吸水ポンプ設定スイッチ３２ｅにより吸水ポンプ２７の動作モードを設定した後に、洗い時間設定スイッチ３２ｂ、すすぎ回数設定スイッチ３２ｃ、脱水時間設定スイッチ３２ｄにより、コース内容を切り換えた場合、たとえば、すすぎ回数を１回に設定した場合は、吸水ポンプ２７の動作設定を取り消し、吸水ポンプ表示部３３ｅの「洗い」、「すすぎ１」が消灯するようにしている。
【００４３】
上記構成において動作を説明すると、洗い時間設定スイッチ３２ｂを押すたびに、洗い時間が初期の時間設定から１分ずつ減少し、０分になった場合には、設定内容表示部３３ｃの洗い時間表示が消灯し、続けて洗い時間設定スイッチ３２ｂを押すと、１５分表示から再び１分ずつ減算し、好みの洗濯時間を設定できる。また、すすぎ回数設定スイッチ３２ｃを押すたびに、注水すすぎの設定とすすぎ回数が交互に、注水の有り無し設定と回数の減少するように変化し、すすぎ回数と注水すすぎが設定できる。さらに、脱水時間設定スイッチ３２ｄを押すたびに、脱水時間が初期の時間設定から１分ずつ減少し、０分になった場合には、設定内容表示部３３ｃの脱水時間表示が消灯し、続けて脱水時間設定スイッチ３２ｄを押すと９分表示から再び１分ずつ減算し、好みの脱水時間を設定できる。
【００４４】
吸水ポンプ２７の動作設定は、（表２）に示すように、洗いの設定がなしの場合、すなわち、０分の場合は吸水ポンプ２７を使用する設定ができない。また、同様に、すすぎ回数の設定が０回の場合は、すすぎ時に吸水ポンプ２７を使用する設定ができない。さらに、すすぎの設定が１回の場合には、そのすすぎが一連の洗濯行程の最後のすすぎになるため、吸水ポンプ２７の設定をすることができない。
【００４５】
予め吸水ポンプ２７を洗いおよびすすぎで使用するモード設定を行っているとき、洗い時間設定スイッチ３２ｂ、すすぎ回数設定スイッチ３２ｃ、脱水時間設定スイッチ３２ｄなどのマニュアル設定スイッチによりコース内容を変更させると、吸水ポンプ２７の動作設定と矛盾が生じることがある。すなわち、洗いで吸水ポンプ２７を設定しているが、洗い時間を０分に設定した場合などである。
【００４６】
このような場合にコース内容を変更すると、自動的に吸水ポンプ２７の動作設定を変更する。すなわち、洗いがない設定に変更した場合は、洗い時の吸水ポンプ２７の動作設定を取消し、すすぎを１回以下に変更した場合は、すすぎ時の吸水ポンプ２７の動作設定を取り消す。また、このとき、再び、洗いを設定するかすすぎを２回以上に設定した場合には、吸水ポンプ２７の動作設定を自動的に復活させる。
【００４７】
この設定変更操作は、吸水ポンプ２７の動作設定が洗いのみに設定されたときも、同様である。また、コース内容は動作運転中に変更も可能であり、このときも、すすぎが１回以下に変更した場合は、同様にすすぎ時の吸水ポンプ２７の動作を取り消す。
【００４８】
また、吸水ポンプ２７の動作状態を表示手段３３の吸水ポンプ表示部３３ｅにより表示する。洗い行程において、吸水ポンプ２７を使用する設定では、吸水ポンプ表示部３３ｅの「洗い」が点灯し、洗いとすすぎの両方で吸水ポンプ２７を使用する設定では、吸水ポンプ表示部３３ｅの「洗い」、「すすぎ１」が点灯する。吸水ポンプ２７の動作モードを設定後に、コース内容を変更することにより、吸水ポンプ２７の動作が不適切な条件に設定された場合は、吸水ポンプ２７の動作を自動的に取り消されるとともに、設定状態表示が消えて、使用者に設定状態を報知する。
【００４９】
したがって、吸水ポンプ２７の動作モードを設定した後に、マニュアル設定スイッチによりコース内容を切り換えた場合に、設定されたコース内容に応じて吸水ポンプ２７の動作モードを切り換え、切り換えた吸水ポンプ２７の動作モードを吸水ポンプ表示ぶ３３ｅに表示することで、不適切に風呂水使用を行い、衣類に臭い等が移って仕上がったり、風呂水を使用したことにより柔軟剤の効果が薄れるのを防止でき、さらに、吸水ポンプの動作状態を表示するので、操作および現在設定の状態を確認することができ、吸水ポンプ２７の動作設定の手順に関係なく所定の設定をすることができるため、設定操作が容易になり、誤操作を防止できる。

[0018]
The motor 21 is disposed below the water receiving tub 10 and drives the pulsator 11 through the V-belt 22 and the speed reduction mechanism 23 during washing and rotates the washing / dehydrating tub 12 during dehydration. The drain valve 24 controls the drainage of the washing water in the washing and dewatering tub 12 and is disposed below the water receiving tub 10. An upper cover 25 is provided above the washing machine outer frame 14, and a water supply valve 26, a water absorption pump 27, and a control device 28 are provided. The control device 28 controls the motor 21, the drain valve 24, the water supply valve 26, and the like. The fluid balancer 29 reduces vibration of the washing / dehydrating tub 12 during dehydration, and is provided on the upper portion of the washing / dehydrating tub 12.
[0019]
The control device 28 is configured as shown in FIG. 1, and the control means 30 is constituted by a microcomputer, and the motor 21, the drain valve 24, The water supply valve 26, the water absorption pump 27, etc. are controlled. The switch input means 32 sets the water level, the washing time, the number of times of rinsing, the dehydration time, and the like. The contents set by the switch input means 32 are displayed on the display means 33.
[0020]
The water level detection means 34 detects the water level in the washing and dewatering tub 12. The cloth amount determining means 35 determines the amount of cloth contained in the washing and dewatering tub 12 based on the number of pulses from the voltage at both ends of the phase advance capacitor 36 during inertial rotation when the motor 21 is turned off after the motor 21 is driven. To do. In addition, 37 is a power switch and 38 is an alternating current power supply.
[0021]
As shown in FIG. 3, the switch input means 32 includes a water level setting switch 32a, a washing time setting switch 32b, a rinse number setting switch 32c, a dehydration time setting switch 32d, a water absorption pump setting switch 32e, a course setting switch 32f, a start / temporary operation. The stop switch 32g is used. The display means 33 includes a water level display unit 33a, a washing, rinsing, and dehydration process progress display unit 33b, a setting content display unit 33c for washing, rinsing, and dehydration, a remaining time display unit 33d, a water absorption pump display unit 33e, and a course display unit. 33f and the like.
[0022]
When setting the operation of the water absorption pump 27, by pressing the water absorption pump setting switch 32e, as shown in (Table 1), the mode for operating the water absorption pump 27 (using bath water) at the time of washing, at the time of washing and rinsing The mode in which the water absorption pump 27 is operated and the mode in which the water absorption pump 27 is not operated can be switched and set. At this time, according to the setting mode, “washing” and “rinse 1” on the water absorption pump display section 33e are lit.
[0023]
[Table 1]

[0024]
In Table 1, “◯” indicates that the water absorption pump 27 is operated, and “X” indicates that the water absorption pump 27 is not operated.
[0025]
Here, in the case of a course setting in which the water absorption pump 27 is used up to the rinsing process, the final rinsing in a series of washing processes is always performed with tap water controlled by the water supply valve 26 without using bath water. At the end of the rinse, clean water is used to prevent odors such as bath water from remaining in the finished laundry. (Table 1) shows the case where the “rush course” is set by the course setting switch 32f. In the “rush course”, when the water level is set to “low water level” or less, the rinse is set once. Like to do.
[0026]
When the water level is switched by the water level setting switch 32a after setting the operation mode of the water absorption pump 27 by the water absorption pump setting switch 32e, the control means 30 automatically sets the operation mode of the water absorption pump 27 according to the set water level. The operation mode of the switched water suction pump 27 is displayed on the display means 33.
[0027]
The operation in the above configuration will be described. When the power switch 37 is turned on, a “standard course” for executing a standard washing process is set. Here, when the start / pause switch 32g is pressed, washing starts automatically according to a predetermined procedure.
[0028]
Now, when the course setting switch 32f is set to “Hurry course” and the water absorption pump setting switch 32e is set to the mode in which the water absorption pump 27 is operated when the water absorption pump 27 is washed and rinsed, the “ “Wash” and “Rinse 1” light up. Here, during operation of the water absorption pump 27, the water absorption pump display section 33e blinks, and the operation stroke of the water absorption pump 27 is displayed.
[0029]
In this state, when the water level setting switch 32a is set to “low water level”, the “low water level” is a mode in which the water absorption pump 27 is not operated as shown in (Table 1). It switches so that it may not operate | move, turns off "washing" and "rinse 1" of the water absorption pump display part 33e, and notifies a user of a setting state.
[0030]
In the "hurry course", in order to perform rinsing in a short time. Rinsing is performed while water is supplied to the washing / dehydrating tub 12. In this case, washing is performed at a low water level with a small amount of washing compared to washing at a high water level with a large amount of washing. In this case, since the amount of water entering the washing / dehydrating tub 12 is larger than the washing amount, the rinsing performance is improved.
[0031]
Therefore, it is possible to obtain a sufficient rinsing performance in a case where the rinsing is performed twice in the case of the high water level and in a single time at the low water level. Therefore, when the water level below the low water level is set in the “hurry course”, the rinse is performed only once. Accordingly, since the first rinse is the last rinse of the washing course, the water absorption pump 27 is switched so as not to operate automatically, and the bath water is rinsed with tap water without using the bath water. It can prevent smell transfer.
[0032]
Furthermore, since the operation state of the water absorption pump 27 is displayed by the water absorption pump display unit 33e of the display means 33, the operation and the current setting state can be confirmed, and the predetermined setting is possible regardless of the operation setting procedure of the water absorption pump 27. Therefore, the setting operation is facilitated and erroneous operation can be prevented.
[0033]
In this embodiment, after setting the “rush course” and setting the mode in which the water absorption pump 27 is operated when the water absorption pump 27 is rinsed and rinsed, the water absorption pump 27 is operated when the “low water level” is set. However, the present invention is not limited to this, and even if another course is set and other than “low water level” is set, if the number of times of rinsing becomes one, the water absorption pump 27 is automatically turned on. By switching so that it does not operate normally, rinsing with tap water without using bath water can prevent the smell of bath water from being transferred.
[0034]
(Example 2)
The control means 30 in FIG. 1 switches the operation mode of the water absorption pump 27 based on the result of the cloth amount determination by the cloth amount determination means 35. Other configurations are the same as those of the first embodiment.
[0035]
Describing the operation in the above configuration, the cloth amount determining means 35 determines the cloth amount in the washing and dewatering tub 12 based on the inertia rotation speed of the pulsator 11 immediately after the motor 21 is operated for a predetermined time. That is, before the start of washing, the motor 21 is turned on for 0.5 seconds, for example, and the number of pulses generated in the phase advance capacitor 36 when the inertia of the pulsator 11 is stopped is counted. When the number of pulses is large, the load is light and the amount of cloth is small.
[0036]
At this time, when the amount of cloth is less than the rated capacity, the amount of water with respect to the cloth is increased, so that the rinsing performance is improved. This tendency is particularly noticeable in the “Hurry Course” where the time is shortened by rinsing with water. Therefore, in the case of the “hurry course”, if it is determined that the amount of cloth is small, control is performed so that washing is completed in a short time by rinsing once. If the rinsing is performed once, as described above, the use of the water suction pump 27 in the rinsing process is inappropriate. Therefore, even if it is set, the water suction pump operation mode is automatically canceled.
[0037]
Therefore, if it is determined that the amount of cloth is small, the rinsing is performed once and the water absorption pump 27 is automatically switched off so that the bath water is rinsed with tap water without using the bath water. It can prevent the smell of water from moving.
[0038]
In this embodiment, when the “rush course” is set and it is determined that the amount of cloth is small, the water absorption pump 27 is switched so as not to automatically operate. However, the present invention is not limited to this. Even when other courses are set, if the number of times of rinsing is one according to the determination result of the cloth amount, the water absorption pump 27 is switched so as not to automatically operate, so that the tap water can be used without using bath water. By rinsing, the smell of bath water can be prevented.
[0039]
Example 3
The control means 30 in FIG. 1 pushes the water absorption pump setting switch 32e when the washing time, the number of times of rinsing, and the dehydration time are individually set by the washing time setting switch 32b, the rinsing time setting switch 32c, and the dehydration time setting switch 32d. Then, as shown in (Table 2), the mode is set by switching the mode in which the water absorption pump 27 is operated (using bath water) at the time of washing, the mode in which the water absorption pump 27 is operated at the time of washing and rinsing, and the mode in which the water absorption pump 27 is not operated. I can do it. At this time, according to the setting mode, “washing” and “rinse 1” on the water absorption pump display section 33e are lit.
[0040]
[Table 2]

[0041]
In (Table 2), a circle mark indicates that the water absorption pump 27 is operated, and a cross mark indicates that the water absorption pump 27 is not operated.
[0042]
Further, the control means 30 sets the operation mode of the water absorption pump 27 by the water absorption pump setting switch 32e, and then switches the course contents by the washing time setting switch 32b, the rinse count setting switch 32c, and the dehydration time setting switch 32d. For example, when the number of times of rinsing is set to 1, the operation setting of the water suction pump 27 is canceled, and “washing” and “rinsing 1” on the water suction pump display unit 33e are turned off.
[0043]
The operation in the above configuration will be described. Each time the washing time setting switch 32b is pressed, the washing time is reduced by 1 minute from the initial time setting, and when it becomes 0 minutes, the washing time display on the setting content display section 33c is displayed. When is turned off and the washing time setting switch 32b is continuously pressed, the desired washing time can be set by subtracting one minute again from the 15 minute display. Further, each time the rinsing number setting switch 32c is pressed, the setting of the rinsing and the rinsing number are alternately changed so as to decrease the number of irrigation and the setting of the irrigation, and the number of rinsing and the rinsing can be set. Further, each time the dehydration time setting switch 32d is pressed, when the dehydration time is decreased by 1 minute from the initial time setting and becomes 0 minutes, the dehydration time display on the setting content display section 33c is turned off and continuously. When the dehydration time setting switch 32d is pressed, the desired dehydration time can be set by subtracting 1 minute from the 9 minute display again.
[0044]
As shown in (Table 2), the operation setting of the water absorption pump 27 cannot be set to use the water absorption pump 27 when there is no washing setting, that is, when it is 0 minute. Similarly, when the number of times of rinsing is 0, it is not possible to use the water absorption pump 27 during rinsing. Furthermore, when the rinse setting is performed once, the rinse is the last rinse in a series of washing steps, and thus the water absorption pump 27 cannot be set.
[0045]
When the mode for using the water absorption pump 27 for washing and rinsing is set in advance, if the course contents are changed by manual setting switches such as the washing time setting switch 32b, the number of times of rinsing setting switch 32c, and the dehydration time setting switch 32d, An inconsistency with the operation setting of the pump 27 may occur. That is, the water absorption pump 27 is set for washing, but the washing time is set to 0 minutes.
[0046]
If the course content is changed in such a case, the operation setting of the water suction pump 27 is automatically changed. That is, when the setting is changed to a setting without washing, the operation setting of the water absorption pump 27 at the time of washing is canceled, and when the rinsing is changed to one time or less, the operation setting of the water absorption pump 27 at the time of rinsing is canceled. Further, at this time, when the washing is set again or more than twice, the operation setting of the water absorption pump 27 is automatically restored.
[0047]
This setting change operation is the same when the operation setting of the water absorption pump 27 is set to only washing. The course contents can be changed during the operation operation. At this time, if the rinse is changed to one time or less, the operation of the water absorption pump 27 during the rinse is similarly canceled.
[0048]
Further, the operation state of the water absorption pump 27 is displayed by the water absorption pump display section 33 e of the display means 33. In the setting of using the water absorption pump 27 in the washing process, “washing” of the water absorption pump display portion 33e is lit, and in the setting of using the water absorption pump 27 for both washing and rinsing, “washing” of the water absorption pump display portion 33e is performed. "Rinse 1" lights up. When the operation of the water absorption pump 27 is set to an inappropriate condition by changing the course content after setting the operation mode of the water absorption pump 27, the operation of the water absorption pump 27 is automatically canceled and the set state The display disappears and the user is notified of the setting status.
[0049]
Accordingly, when the course content is switched by the manual setting switch after setting the operation mode of the water absorption pump 27, the operation mode of the water absorption pump 27 is switched according to the set course content, and the operation mode of the switched water absorption pump 27 is switched. Is displayed on the water absorption pump display 33e to prevent improper use of bath water, odors, etc. transferred to clothing, or the use of bath water to reduce the effect of the softener. Since the operation state of the water absorption pump is displayed, the operation and the current setting state can be confirmed, and a predetermined setting can be performed regardless of the operation setting procedure of the water absorption pump 27, so that the setting operation is easy. Thus, erroneous operation can be prevented.
