Description

本発明は、水流の組み合わせによって、衣類を傷めず、汚れの除去を効率的に行う洗濯機に関するものである。   The present invention relates to a washing machine that efficiently removes dirt without damaging clothing by a combination of water flows.

従来、この種の洗濯機は図4に示すような構成が一般的であった(例えば、特許文献1参照)。以下、その構成について説明する。   Conventionally, this type of washing machine is generally configured as shown in FIG. 4 (see, for example, Patent Document 1). Hereinafter, the configuration will be described.

図4は、特許文献1に記載された従来の洗濯機を示すものである。図4において、洗濯兼脱水槽1は、底面にパルセータ2を回転自在に配設し、水受け槽3は、洗濯兼脱水槽1の外側に設けており、モータ4は、Vベルト5および減速機構兼クラッチ6を介して、洗濯兼脱水槽1またはパルセータ2を駆動する。排水弁7は洗濯兼脱水槽1内の洗濯水を排水し、給水弁8は洗濯兼脱水槽1内に給水するものである。また、水受け槽3は外枠9にサスペンション10によって防振支持されている。環状流体バランサー11は洗濯兼脱水槽1の上部に設け、脱水時の振動を低減するものである。   FIG. 4 shows a conventional washing machine described in Patent Document 1. As shown in FIG. In FIG. 4, the washing / dehydrating tub 1 has a pulsator 2 rotatably disposed on the bottom surface, the water receiving tub 3 is provided outside the washing / dehydrating tub 1, and the motor 4 includes a V-belt 5 and a speed reducer. The washing / dehydrating tub 1 or the pulsator 2 is driven via the mechanism / clutch 6. The drain valve 7 drains the washing water in the washing / dehydration tank 1, and the water supply valve 8 supplies water to the washing / dehydration tank 1. In addition, the water receiving tank 3 is supported by the suspension 10 on the outer frame 9 with vibration isolation. The annular fluid balancer 11 is provided in the upper part of the washing and dewatering tank 1 to reduce vibration during dehydration.

制御手段12は、モータ4、排水弁7、給水弁8などを制御して、洗濯、すすぎ、脱水の一連の行程を逐次制御するものである。   The control means 12 controls the motor 4, the drain valve 7, the water supply valve 8, etc., and sequentially controls a series of steps of washing, rinsing and dewatering.

上記構成において動作を説明すると、セータなどのデリケートな衣類を洗う場合、洗濯兼脱水槽1に衣類と所定量の洗剤を投入した後、運転を開始すると、制御手段12は給水弁8を制御して洗濯兼脱水槽1内に所定量の水を給水し、その後、モータ4を制御してパルセータ2を駆動する。   The operation in the above configuration will be described. When washing delicate clothes such as a sweater, the control means 12 controls the water supply valve 8 when the operation is started after putting clothes and a predetermined amount of detergent into the washing and dewatering tub 1. Then, a predetermined amount of water is supplied into the washing and dewatering tub 1, and then the motor 4 is controlled to drive the pulsator 2.

このとき、デリケートな衣類が傷まないように、制御手段12は、通電を一部カット(モータ4の通電比率を電源の半波を1としたとき、1/3通電としている)し、パルセータ2を低速で回転させている。このパルセータ2の回転により、洗濯兼脱水槽1内の衣類は撹拌され、汚れが落ちる。
特開平10−323482号公報
At this time, the control means 12 partially cuts the energization so that the delicate clothes are not damaged (the energization ratio of the motor 4 is 1/3 energization when the half wave of the power source is 1), and the pulsator 2 Is rotating at low speed. By the rotation of the pulsator 2, the clothes in the washing and dewatering tub 1 are agitated and the dirt is removed.
Japanese Patent Laid-Open No. 10-323482

しかしながら、従来の洗濯機は、デリケートな衣類を洗う場合、パルセータ2を低速で回転させているだけであるため、衣類の汚れは落ちにくく、その汚れを除去するためには洗い時間、また、すすぎ時間を長く設定しなければならないといった問題を有していた。   However, since the conventional washing machine only rotates the pulsator 2 at a low speed when washing delicate clothes, it is difficult to remove dirt from the clothes. In order to remove the dirt, washing time and rinsing are performed. There was a problem that the time had to be set longer.

本発明は、前記従来の課題を解決するもので、パルセータを低速で回転する弱水流行程と、パルセータを高速で回転させる強水流行程にて、衣類を洗うことで、デリケートな衣類を傷めず、かつ短時間で洗濯することができる洗濯機を提供することを目的とする。   The present invention solves the above-mentioned conventional problems, washing clothes in a weak water fashion that rotates the pulsator at a low speed and a strong water fashion that rotates the pulsator at a high speed, without damaging delicate clothes, An object of the present invention is to provide a washing machine capable of washing in a short time.

前記従来の課題を解決するために、本発明の洗濯機は、モータと、洗濯槽兼脱水槽と、前記洗濯槽兼脱水槽の底部にあって前記モータの駆動により回転自在に配設したパルセータと、洗い、すすぎ行程等を遂次制御する制御手段を備え、洗い、またはすすぎ行程において、前記制御手段は前記モータへの通電を一部周波数カットして前記パルセータを低速で回転する弱水流行程と、前記パルセータを高速で回転させる強水流行程とを有してなるものである。   In order to solve the above-described conventional problems, a washing machine of the present invention includes a motor, a washing tub / dehydration tub, and a pulsator disposed at the bottom of the washing tub / dehydration tub and rotatably disposed by driving the motor. And a control means for successively controlling the washing and rinsing process, etc., in the washing or rinsing process, the control means partially cuts the frequency of energization to the motor and rotates the pulsator at a low speed. And a strong water fashion that rotates the pulsator at high speed.

これにより、デリケートな衣類を、弱水流行程にて傷めず洗濯し、かつ強水流行程にて短時間で洗濯することができるものである。   Thereby, delicate clothes can be washed without being damaged in the weak water fashion, and can be washed in the short time in the strong water fashion.

本発明の洗濯機は、デリケートな衣類を傷めず、かつ短時間で洗濯することができる。   The washing machine of the present invention can be washed in a short time without damaging delicate clothes.

第1の発明は、モータと、洗濯槽兼脱水槽と、前記洗濯槽兼脱水槽の底部にあって前記モータの駆動により回転自在に配設したパルセータと、洗い、すすぎ、脱水行程等を遂次制御する制御手段を備え、前記制御手段は、洗い行程およびすすぎ行程のうち少なくともいずれか一方の行程において、前記モータへの通電を一部周波数カットして前記パルセータを低速で回転する弱水流行程と、前記パルセータを高速で回転させる強水流行程の両方を実行することにより、衣類を傷めない弱水流と、汚れが落ちやすい強水流を組み合わせることができるため、デリケートな衣類を傷めず、かつ短時間で洗濯することができる。   The first invention accomplishes washing, rinsing, dehydration process, and the like with a motor, a washing tub / dehydration tub, a pulsator at the bottom of the washing tub / dehydration tub and rotatably disposed by driving the motor. A control means for performing next control, the control means in the at least one of the washing process and the rinsing process, the weak water prevalence process in which the pulsator is rotated at a low speed by partially cutting off the power to the motor In addition, by executing both the strong water fashion that rotates the pulsator at a high speed, it is possible to combine a weak water flow that does not damage clothes and a strong water flow that easily removes dirt, so that delicate clothes are not damaged and short. Can be washed in time.

第2の発明は、第1の発明の制御手段が、弱水流行程と強水流行程を交互に実行することにより、衣類を傷めない弱水流と、汚れが落ちやすい強水流とを効率良く組み合わせることができるため、デリケートな衣類を傷めず、かつ短時間で洗濯することができる。   In the second aspect of the invention, the control means of the first aspect of the invention efficiently combines a weak water flow that does not damage clothes and a strong water flow that easily removes dirt by executing the weak water fashion and the strong water fashion alternately. Therefore, it can be washed in a short time without damaging delicate clothes.

第3の発明は、第1または第2の発明の制御手段が、洗い行程およびすすぎ行程のうち少なくともいずれか一方の行程の開始時に、強水流行程を実行した後、弱水流行程と強水流行程を交互に実行することにより、給水後には水面に浮いている衣類を、行程の開始時に、強水流行程によって水中に引き込み、衣類に水をしみ込ませることができるので、衣類を水中に浸漬させることができ、その後の行程で効果的な洗濯、すすぎを実行することができる。   According to a third aspect of the present invention, after the control means of the first or second aspect of the invention executes the strong water epidemic period at the start of at least one of the washing process and the rinsing process, the weak water epidemic period and the strong water epidemic period are performed. By alternately executing, clothing that floats on the water surface after water supply can be drawn into the water at the beginning of the stroke due to the strong water fashion, and the clothing can be soaked in water, so that the clothing is immersed in water And effective washing and rinsing can be performed in the subsequent steps.

第4の発明は、第3の発明の制御手段が、洗い行程およびすすぎ行程のうち少なくともいずれか一方の行程の開始時に実行する強水流行程の水流を、その後の強水流行程の水流より強くなるように設定したことにより、給水後には水面に浮いている衣類を、行程の開始時に、強い水流の強水流行程によって水中に強力に引き込み、衣類に水を十分にしみ込ませることができるので、衣類を水中に浸漬させることができ、その後の行程でさらに効果的な洗濯、すすぎを実行することができる。   In the fourth aspect of the invention, the strong water epidemic water flow executed at the start of at least one of the washing process and the rinsing process by the control means of the third invention is stronger than the water flow of the subsequent strong water epidemic stage. With this setting, clothing that floats on the water after water supply can be drawn into the water strongly at the beginning of the stroke by the strong water trend of strong water flow, so that the clothing can be sufficiently saturated with water. Can be immersed in water, and more effective washing and rinsing can be performed in the subsequent steps.

第5の発明は、第1〜4のいずれか1つの発明の洗濯機が、パルセータの裏面側に形成したポンプ室と、前記ポンプ室から前記洗濯槽兼脱水槽の側壁上方に向かって送水し前記洗濯槽兼脱水槽中央に向け散水すべく開口部を一端に有する循環水路とを備えたことにより、洗濯途中に衣類が洗濯水の水面上に浮き上がった場合でも、衣類に洗濯水をかけて汚れに作用させることができるため、衣類の洗いムラを減少させることができる。   In a fifth aspect of the invention, the washing machine according to any one of the first to fourth aspects of the present invention supplies water to the pump chamber formed on the back side of the pulsator, and from the pump chamber toward the upper side wall of the washing tub / dehydration tub.

(Embodiment 1)
FIG. 1 is a longitudinal sectional view of a washing machine according to Embodiment 1 of the present invention, FIG. 2 (a) is an energization waveform diagram during the strong water fashion of the washing machine, and FIG. 2 (b) is a weakness of the washing machine. FIG. 3 shows an operation time chart of the washing machine.

図1において、洗濯兼脱水槽13は、底面にパルセータ14を回転自在に配設し、水受け槽15は、洗濯兼脱水槽13を内包するように設けている。モータ16は、Vベルト17および減速機構兼クラッチ18を介して、洗濯兼脱水槽13およびパルセータ14を駆動する。排水弁19は洗濯兼脱水槽13内の洗濯水を排水し、給水弁20は洗濯兼脱水槽13内に給水するものである。また、水受け槽15は外枠21にサスペンション22によって防振支持されている。環状の流体バランサー23は洗濯兼脱水槽13の上部に設け、脱水時の振動を低減するものである。   In FIG. 1, a washing / dehydrating tank 13 has a pulsator 14 rotatably disposed on the bottom surface, and a water receiving tank 15 is provided so as to contain the washing / dehydrating tank 13. The motor 16 drives the washing / dehydrating tub 13 and the pulsator 14 via the V belt 17 and the speed reduction mechanism / clutch 18. The drain valve 19 drains the washing water in the washing / dehydrating tub 13, and the water supply valve 20 supplies water to the washing / dehydrating tub 13. Further, the water receiving tank 15 is supported by the suspension 22 on the outer frame 21 with vibration isolation. An annular fluid balancer 23 is provided at the top of the washing and dewatering tank 13 to reduce vibration during dehydration.

制御手段24は、モータ16、排水弁19、給水弁20などを制御して、洗濯、すすぎ、脱水の一連の行程を逐次実行するものである。   The control means 24 controls the motor 16, the drain valve 19, the water supply valve 20, etc., and sequentially executes a series of steps of washing, rinsing and dewatering.

洗濯兼脱水槽13の内側面部には、開口部25を備えた循環水路カバー26と洗濯兼脱水槽13とで循環水路27が形成されている。モータ16に通電されると、パルセータ14の回転により、パルセータ14の裏面の洗濯水は、パルセータ14の下側羽根28により、その外周に形成されたポンプ室29から循環水路27を通り、開口部25より洗濯兼脱水槽13内に吐出される。   On the inner side surface of the washing and dewatering tub 13, a circulation water channel 27 is formed by the circulation water channel cover 26 having the opening 25 and the washing and dewatering tub 13. When the motor 16 is energized, the rotation of the pulsator 14 causes washing water on the back surface of the pulsator 14 to pass through the circulating water channel 27 from the pump chamber 29 formed on the outer periphery thereof by the lower blades 28 of the pulsator 14, 25 is discharged into the washing and dewatering tank 13.

制御手段24は、図2(b)のように、モータ16への通電比率を電源の半波を1としたとき、1/3通電として、通電を一部カットして、パルセータ14を低速で回転する弱水流行程と、図2(a)のように、モータ16への通電比率を1/1通電とした、パルセータ14を高速で回転させる強水流行程とを有している。この強水流行程の中には、強水流(例えば、1.0秒オン−4.0秒オフ)と、標準水流(例えば、0.5秒オン−4.0秒オフ)とを設けている。   As shown in FIG. 2 (b), the control means 24 sets the energization ratio to the motor 16 to 1 when the half wave of the power supply is 1, cuts the energization partly and sets the pulsator 14 at a low speed. As shown in FIG. 2 (a), there is a weak water fashion that rotates, and a strong water fashion that rotates the pulsator 14 at a high speed with the energization ratio to the motor 16 being 1/1. In the strong water epidemic, a strong water flow (for example, 1.0 second on-4.0 second off) and a standard water flow (for example, 0.5 second on-4.0 second off) are provided. .

また、強水流行程の水流は、開口部25より洗濯水を洗濯兼脱水槽13内に吐出し、弱水流行程の水流(例えば、3.0秒オン−5.5秒オフ)は、開口部25より洗濯水が吐出しないように設定している。他の構成は従来と同じである。   In addition, the water flow in the strong water fashion is discharged from the opening 25 into the washing and dehydrating tank 13, and the water flow in the weak water fashion (for example, 3.0 seconds on-5.5 seconds off) 25 so that washing water is not discharged. Other configurations are the same as the conventional one.

上記構成において動作を説明すると、洗濯兼脱水槽13に衣類と洗剤を投入し、運転を開始すると給水弁20を開いて所定の水位まで給水した後、モータ16を駆動する。そして、モータ16の動力は洗濯軸を介してパルセータ14に伝達され、パルセータ14が回転する。   To explain the operation in the above configuration, clothes and detergent are put into the washing and dewatering tank 13, and when the operation is started, the water supply valve 20 is opened to supply water to a predetermined water level, and then the motor 16 is driven. The power of the motor 16 is transmitted to the pulsator 14 through the washing shaft, and the pulsator 14 rotates.

このとき、図3に示すように、制御手段24は、強水流行程の強水流を一定時間(例えば、30秒)実行する。その後、弱水流行程と強水流行程の標準水流を一定時間づつ交互に実行する(例えば、弱水流行程50秒、強水流行程20秒を交互に実行)。   At this time, as shown in FIG. 3, the control means 24 executes a strong water flow as strong as the strong water epidemic for a certain time (for example, 30 seconds). Thereafter, the standard water flow for the weak water epidemic and the strong water epidemic are alternately executed at regular intervals (for example, the weak water epidemic is about 50 seconds and the strong water epidemic is about 20 seconds).

給水終了の時点では衣類は乾いているため、水面に浮いてしまっている。そこで、最初に強水流行程の強水流を一定時間実行することにより、洗い行程開始時に、洗濯水に浮いている衣類を、強水流行程によって水中に引き込み、衣類に水をしみ込ませることができるので、洗濯水に十分に浸漬させることができる。それにより、その後の行程で、効果的な洗濯、すすぎを実行することができる。   Since the clothes are dry at the end of the water supply, they float on the surface of the water. Therefore, by first executing the strong water flow of the strong water epidemic period for a certain period of time, the clothes floating in the washing water can be drawn into the water by the strong water epidemic period and water can be soaked into the clothes at the start of the washing process. It can be sufficiently immersed in washing water. Thus, effective washing and rinsing can be performed in the subsequent process.

また、上記したように、弱水流行程と強水流行程を交互に最適な時間で実行することにより、弱水流行程においては衣類を傷めずやさしく洗いつつ、強水流行程においては衣類を傷めずに、しっかりと汚れを落とすことができるため、デリケートな衣類を傷めず、かつ短時間で洗濯することができる。このとき、弱水流行程の実行時間を強水流行程の実行時間より長く設定することにより、デリケートな衣類に対し、弱水流行程でつけ置き洗いの効果、すなわち、衣類の汚れを衣類から浮かし、強水流行程でその汚れを衣類から引き離すことができるものである。また、強水流行程の時間は短いので、デリケートな衣類を傷めることなく、洗濯を行うことができるものである。   In addition, as described above, by executing the weak water epidemic stage and the strong water epidemic period alternately at the optimal time, while washing the clothes gently without damaging the clothes in the weak water epidemic stage, without damaging the clothes in the strong water epidemic stage, Since the dirt can be removed firmly, the delicate clothes can be washed without damaging the clothes. At this time, by setting the execution time of the weak water epidemic period to be longer than the execution time of the strong water epidemic period, the effect of deferment washing for delicate clothes, that is, the dirt on the clothes floats from the clothes and is strong. The dirt can be separated from the clothes in the water fashion. Moreover, since the time of strong water epidemic is short, washing can be performed without damaging delicate clothes.

また、洗い行程開始時の強水流の後は、弱水流行程と強水流行程を交互に最適な時間で実行するが、この時の強水流行程の水流は、標準水流に設定している。これは、洗い行程開始時の強水流によって衣類に洗濯水が十分しみ込み、衣類が洗濯水内に十分に浸漬しているため、強水流行程の水流を標準水流に設定することにより、さらに衣類を傷めず、やさしく洗いあげることができる。   In addition, after the strong water flow at the start of the washing process, the weak water epidemic process and the strong water epidemic process are alternately executed at an optimal time, and the water flow at the strong water epidemic period at this time is set to a standard water stream. This is because the washing water is sufficiently soaked in the clothing by the strong water flow at the start of the washing process, and the clothing is sufficiently immersed in the washing water. Can be washed gently without damaging.

また、セータなどの衣類は浮きやすいため、洗い中でも水面より上に浮き上がってしまう場合がある。そこで、強水流行程の水流は、開口部25より洗濯水を散水させるように設定していることにより、水面から上にある衣類にも洗濯水をかけて汚れに作用させることができる。   Also, since clothes such as theta tend to float, they may float above the water surface even during washing. Therefore, the water flow of the strong water fashion level is set so that the washing water is sprinkled from the opening 25, so that the clothes above the water surface can also be washed to act on the dirt.

さらに、開口部25からの洗濯水の散水量が多すぎる場合、泡が立ちすぎる恐れがあるため、弱水流行程の水流は、開口部25より洗濯水が吐出しないように、モータ16への通電比率を設定している。これにより、散水による泡の立ちすぎも抑えつつ、洗いむらを少なくすることができる。   Further, if the amount of water sprayed from the opening 25 is too large, bubbles may be formed too much. Therefore, the water flow in the fashion of weak water is energized to the motor 16 so that the washing water is not discharged from the opening 25. The ratio is set. As a result, it is possible to reduce washing unevenness while suppressing excessive formation of bubbles due to watering.

なお、制御手段24は、すすぎ行程においても同じ動作を行うようにしてもよい。   The control unit 24 may perform the same operation in the rinsing process.

以上のように、本発明にかかる洗濯機は、デリケートな衣類を傷めず、かつ短時間で洗濯することが可能となるので、水流の組み合わせによって、衣類を傷めず、汚れの除去を効率的に行う洗濯機等として有用である。   As described above, since the washing machine according to the present invention can be washed in a short time without damaging delicate clothes, the combination of water currents can efficiently remove dirt without damaging clothes. It is useful as a washing machine to perform.
