Abstract

PROBLEM TO BE SOLVED: To achieve a smooth dewatering operation and realize energy saving by shortening operation time.SOLUTION: In a drainage step after a washing step or a rinsing step, cloth quality of laundry is determined according to detected and measured water quantity, cloth quantity and drainage time. Also, a water-containing condition of the laundry is detected, and in the case where it is determined that the laundry is in the water-containing condition with sufficient water contained, a washing and dewatering tub 4 is quickly risen to predetermined rotational frequency by driving a motor 6, and then a contained-water removal step is performed in which the water contained in the laundry is drained once and the drive of the motor 6 is turned OFF. After the contained-water removal step, shift is made to a normal dewatering step. Thereby, vibration can be prevented from getting large as a result of high-speed dewatering rotation with the laundry being in an unbalanced state in the washing and dewatering tub 4, and a smooth dewatering operation can be achieved and also energy saving can be realized by shortening the operation time.SELECTED DRAWING: Figure 3

Description

本発明は,洗濯兼脱水槽を回転させながら洗濯や脱水を行う洗濯機に関する。   The present invention relates to a washing machine that performs washing and dewatering while rotating a washing and dewatering tank.
従来,この種の洗濯機は、洗い、及び、すすぎ行程後の排水行程を制御して脱水へ移行することにより、運転時間の短縮を図り、消費電力量を低減する構成が提案されている(例えば、特許文献1参照)。   Conventionally, this type of washing machine has been proposed to control the drainage process after the washing and rinsing process and shift to dehydration, thereby shortening the operation time and reducing the power consumption ( For example, see Patent Document 1).
図6は、特許文献1に記載された従来の洗濯機の排水制御の動作フローチャートである。   FIG. 6 is an operation flowchart of drainage control of the conventional washing machine described in Patent Document 1.
図6において、例えば、布量検知手段(図示せず)にて決定した設定水位での洗い行程である前の行程から移行して、ステップS51にて、布量検知手段により判定した布量を入力する。つぎに、ステップS52で排水行程に入り、排水弁(図示せず)を駆動して排水を始める。その時点より、ステップS53にて設定水位からの排水時間の計測を開始する。   In FIG. 6, for example, the process shifts from the previous stroke which is the washing stroke at the set water level determined by the cloth amount detecting means (not shown), and the cloth amount determined by the cloth amount detecting means in step S51. input. Next, in step S52, a drainage process is started, and a drain valve (not shown) is driven to start draining. From that time, measurement of the drainage time from the set water level is started in step S53.
そして、水位が水位検知手段(図示せず)のリセット水位以下になると(ステップS54のY)、ステップS55にて設定水位からリセット水位までの排水時間を計測する。ステップS56では、計測した排水時間と布量検知手段からの布量の入力により、残り排水時間を演算し、ステップS57にて、演算した残りの排水時間の間、排水が終わるまで待機し、残り排水時間が経過すると排水行程を終了して次行程の脱水行程へと進む。   When the water level falls below the reset water level of the water level detection means (not shown) (Y in step S54), the drainage time from the set water level to the reset water level is measured in step S55. In step S56, the remaining drainage time is calculated by inputting the measured drainage time and the cloth amount from the cloth amount detecting means. In step S57, the remaining drainage time is calculated until the drainage is completed, and the remaining When the drainage time has elapsed, the drainage process is terminated and the process proceeds to the dehydration process of the next process.
このように、リセット水位からの最適な残り排水時間を求めて排水制御を行ない脱水へ移行することにより、無駄な待機時間を無くし、洗濯終了までの時間を短縮する構成となっている。   In this way, by determining the optimum remaining drainage time from the reset water level and performing drainage control and shifting to dewatering, the configuration eliminates useless waiting time and shortens the time until the end of washing.

以上のように構成した洗濯機について,以下、その動作、作用を説明する。   About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
図3は、本発明の実施の形態における洗濯機の排水制御の動作フローチャートである。   FIG. 3 is an operational flowchart of drainage control of the washing machine in the embodiment of the present invention.
図3において、洗濯兼脱水槽4内に投入された布量が多ければ、衣類そのものが洗濯兼脱水槽4の水抜き用の穴をふさぎ排水時間が長くなり、含水量も増加する。そこで、衣類が投入され、電源が投入されると、ステップS1にて、モータ6を駆動して洗濯兼脱水槽4を左右に小刻みに回転させ、布量検知手段13により洗濯兼脱水槽4内の衣類の布量を検知する。   In FIG. 3, if the amount of cloth put in the washing / dehydrating tub 4 is large, the clothes themselves block the drain holes of the washing / dehydrating tub 4 and the drainage time becomes longer, and the water content also increases. Therefore, when clothes are put in and the power is turned on, in step S1, the motor 6 is driven to rotate the washing / dehydrating tub 4 little by little to the left and right, and the cloth amount detecting means 13 causes the inside of the washing / dehydrating tub 4 to move. Detects the amount of clothes on the clothes.
次に、所定の水位,すなわち使用者が設定した水位、または布量に応じた水位まで給水を行い、水位検知手段12により、洗濯兼脱水槽4内の水量を検知(ステップS2)した
後、洗い工程にて衣類の攪拌による洗浄を行う(ステップS3)。
Next, water is supplied to a predetermined water level, that is, a water level set by the user or a water level corresponding to the amount of cloth, and the water level in the washing and dewatering tub 4 is detected by the water level detecting means 12 (step S2). In the washing process, washing is performed by stirring the clothes (step S3).
洗い工程が終わると、排水弁9を駆動して排水を行い、その際に、計時手段15を用いて排水開始から完了までの時間を測定する(ステップS4)。   When the washing process is finished, the drain valve 9 is driven to drain water, and at that time, the time from the drain start to completion is measured using the time measuring means 15 (step S4).
水量が多ければ、排水時間は長くなるため、本実施の形態の洗濯機は、あらかじめ、水量に応じた標準的な排水時間を記憶保持している。また、先述のように衣類の量が増えれば、排水時間も長くなるため、保持している排水時間は布量に応じて補正される。   Since the drainage time becomes longer if the amount of water is large, the washing machine of the present embodiment stores in advance a standard drainage time corresponding to the amount of water. Moreover, since the drainage time becomes longer as the amount of clothing increases as described above, the drainage time held is corrected according to the amount of cloth.
図4は、本実施の形態1における洗濯機に搭載した布質、布量と水量の組み合わせに応じた標準的排水時間のテーブルを示した例である。   FIG. 4 is an example showing a table of standard drainage time corresponding to the combination of the cloth quality, the amount of cloth and the amount of water mounted on the washing machine according to the first embodiment.
図4に示すように、標準的排水時間は、布量が多いほど、また水量が多いほど長くするよう設定している。また、図4のテーブル表から,布量と排水時間に応じて布質を判定する(ステップS5)。   As shown in FIG. 4, the standard drainage time is set to be longer as the amount of cloth is larger and as the amount of water is larger. Further, the cloth quality is determined from the table in FIG. 4 according to the cloth amount and the drainage time (step S5).
図5は、本実施の形態1における洗濯機に搭載した布質、布量と排水時間に応じて衣類の状態が水を多く含んだ含水状態か、水をあまり含んでいない非含水状態かを判定するテーブルを示した例である。   FIG. 5 shows whether the state of the clothes is a water-containing state containing a lot of water or a non-water-containing state that does not contain much water according to the cloth quality, the amount of cloth and the drainage time mounted on the washing machine in the first embodiment. It is an example which showed the table to determine.
ステップS6にて、布質と布量に応じた標準的排水時間と、計測した実排水時間を比較し、その差とステップS5で判定された布質の判定を元に、図5のテーブル表から、衣類が水を多く含んだ含水状態か、水をあまり多く含んでいない非含水状態かを判定する。   In step S6, the standard drainage time corresponding to the fabric quality and the fabric amount is compared with the measured actual drainage time, and the table shown in FIG. 5 is based on the difference and the fabric quality determination determined in step S5. From this, it is determined whether the clothes are in a water-containing state containing a lot of water or in a non-water-containing state in which there is not much water.
衣類が含水状態の場合(ステップS6のYES)は、衣類に多く含まれる水を一旦排出する含水除去工程の動作を行なう(ステップS7)。含水除去工程は、脱水行程と同じように、モータ6とクラッチ7を駆動させて洗濯兼脱水槽4の回転を急速に立ち上げて衣類に含まれる水を一旦排出し、最高回転数ではなく所定の回転数にてモータ6をOFFにして回転数を落とす動作である。   When the clothes are in a water-containing state (YES in step S6), the operation of a water-containing removing process for temporarily discharging water contained in the clothes is performed (step S7). As in the dehydration process, the water content removing step drives the motor 6 and the clutch 7 to quickly start up the rotation of the washing and dehydrating tub 4 to temporarily discharge the water contained in the clothes, and not the maximum number of revolutions. In this operation, the motor 6 is turned off at a rotational speed of 1 to reduce the rotational speed.
含水徐去工程が終わると、あるいは、衣類が含水状態で無い場合(ステップS6のNO)は、通常の脱水工程へと移行する(ステップS8)。   When the water-containing gradual removal process ends, or when the clothing is not in a water-containing state (NO in step S6), the process proceeds to a normal dehydration process (step S8).
以上のように、本実施の形態においては、洗い工程あるいはすすぎ工程後の排水工程において、水位検知手段12と布量検知手段13と計時手段15がそれぞれ検知、計測した水量,布量,排水時間に応じて、洗濯物の布質を判断するとともに、洗濯物の含水状態を検知し、洗濯物が水を十分に含んだ含水状態であると判断した場合、モータ6を駆動させて洗濯兼脱水槽4を所定の回転数まで急速に立ち上げ、洗濯物に含まれる水を一旦排出してモータ6の駆動をOFFにする含水除去工程を行なった後に、通常の脱水工程へ移行する構成とすることにより、洗濯物が洗濯兼脱水槽4内の中でアンバランス状態のままで高速脱水回転して振動が大きくなることを防止し、スムーズな脱水動作の実現と、運転時間の短縮による省エネを実現することができる。   As described above, in the present embodiment, in the draining process after the washing process or the rinsing process, the water level detecting means 12, the cloth amount detecting means 13, and the time measuring means 15 respectively detect and measure the water amount, the cloth amount, and the draining time. Depending on the condition, the cloth quality of the laundry is judged, the moisture content of the laundry is detected, and if the laundry is judged to be in a moisture content sufficiently containing water, the motor 6 is driven to perform washing and removal. The water tank 4 is rapidly started up to a predetermined number of revolutions, and after performing a water removal process for temporarily discharging water contained in the laundry and turning off the motor 6, the process proceeds to a normal dehydration process. As a result, the laundry is prevented from rotating at high speed while rotating in an unbalanced state in the washing / dehydrating tub 4 and vibrations are increased, realizing a smooth dehydration operation and saving energy by shortening the operation time. Realize Door can be.
以上のように,本発明にかかる洗濯機は、排水条件の程度と衣類の布質を判断し、排水条件及び布質条件に応じた脱水回転制御を行うことによって、スムーズな脱水動作の実現と、運転時間の短縮による省エネを実現することが可能となるので、ドラム式他の洗濯機の用途に適用できる。   As described above, the washing machine according to the present invention realizes a smooth dehydrating operation by judging the level of drainage conditions and the cloth quality of clothing, and performing the dewatering rotation control according to the drainage conditions and the cloth condition. Since it is possible to realize energy saving by shortening the operation time, it can be applied to drum-type other washing machines.
