 (本開示の基礎となった知見等)
 発明者らが本開示に想到するに至った当時、風呂清掃用の除菌剤の技術として、ジクロロイソシアヌル酸ナトリウムを含む水溶性の固形剤が知られていた。発明者らは、風呂清掃用の除菌剤の技術をヒントにして、一回使い切りの水溶性の固形剤を投入して洗濯物に固形剤の成分を付与する洗濯機という着想を得た。そして、発明者らは、固形剤の溶解物が洗剤または柔軟剤等の他の洗濯剤と混ざると、化学反応を起こし、除菌性能が低下するという課題があることを発見した。また、固形物の溶解物が洗濯物に付着すると、洗濯物が脱色するおそれがある。発明者らは、これらの課題を解決するために、本開示の主題を構成するに至った。
(Findings, etc. that formed the basis of this disclosure)
At the time the inventors came up with the present disclosure, a water-soluble solid agent containing sodium dichloroisocyanurate was known as a disinfectant technology for bath cleaning. The inventors took a cue from the technology of disinfectants for bath cleaning and came up with the idea of a washing machine that dispenses a single-use water-soluble solid agent to impart solid agent components to laundry. Then, the inventors discovered that when the dissolved solid agent mixes with other laundry agents such as detergents or fabric softeners, a chemical reaction occurs and the sterilization performance deteriorates. Further, if the dissolved solids adhere to the laundry, there is a risk that the laundry will be discolored. In order to solve these problems, the inventors have constructed the subject matter of the present disclosure.

As shown in FIG. 11, water is discharged diagonally downward from the water supply nozzle 12 toward the side wall 80 of the tablet case 63 (see arrow W1). Further, water is discharged diagonally downward from the water supply nozzle 13 toward the outer wall 89 of the softener case 61 on the opposite side (arrow W2).
 水は、側壁80における点P1及び柔軟剤ケース61の外側壁89における点P2に当たって、壁面に沿って下方に流れる。点P1、P2は錠剤Jの頂点の上方であって、収容空間K10の上方におけるメッシュ82上の高さに位置する。衝突後、水が壁面に沿って下方に流れると、錠剤Jの側面に当たり、錠剤Jに吸収される。水が一度側壁80に衝突してから間接的に錠剤Jの側面に当たるため、給水ノズル12、13から直接錠剤Jに当たる場合と比較して、水の勢い及び流速を小さくできる。 The water hits point P1 on the side wall 80 and point P2 on the outer wall 89 of the softener case 61, and flows downward along the wall surface. Points P1 and P2 are located above the apex of the tablet J and at a height above the mesh 82 above the accommodation space K10. After the collision, water flows downward along the wall surface, hits the side of the tablet J, and is absorbed by the tablet J. Since the water once collides with the side wall 80 and then indirectly hits the side surface of the tablet J, the force and flow rate of the water can be reduced compared to when the water hits the tablet J directly from the water supply nozzles 12, 13.
 [動作]
 続いて、図12Aから図15を参照して、除菌コースを実行する際の洗濯機1の動作について説明する。図12Aは、除菌コースにおける処理の流れを示すシーケンス図であり、図12Bから図12Gは、除菌コースの一部の工程における処理の流れを示すシーケンス図である。図13は、除菌コースにおける水位変化を示す図である。図14は、除菌コースにおける給水弁10a、10b及び排水弁9の動作を示す図である。図15は、洗濯槽4の水位を示す図である。
[motion]
Next, with reference to FIGS. 12A to 15, the operation of the washing machine 1 when executing the sterilization course will be described. FIG. 12A is a sequence diagram showing the flow of processing in the sterilization course, and FIGS. 12B to 12G are sequence diagrams showing the flow of processing in some steps of the sterilization course. FIG. 13 is a diagram showing water level changes during the sterilization course. FIG. 14 is a diagram showing the operation of the water supply valves 10a, 10b and the drain valve 9 in the sterilization course. FIG. 15 is a diagram showing the water level of the washing tub 4.
 除菌コースとは、衣類やタオル等のいわゆる洗濯物に付着した菌を除去するために行われる洗濯コースを意味する。1回の除菌コースにおいて、1つの錠剤Jが使用される。除菌コースの終了後には、錠剤Jは、投入前と同じ形状において、錠剤ケース63に残っていないことが想定される。そのため、ユーザは次の除菌コースの前に新たな錠剤Jを錠剤ケース63に投入する。 A sterilization course refers to a washing course that is carried out to remove bacteria attached to so-called laundry items such as clothes and towels. One tablet J is used in one sterilization course. After the sterilization course ends, it is assumed that the tablets J do not remain in the tablet case 63 in the same shape as before they were inserted. Therefore, the user inserts a new tablet J into the tablet case 63 before the next sterilization course.
 まず、図12Aを参照して、除菌コース全体の処理の流れを説明する。図12Aに示すように、除菌コースでは、制御部Cは、順に洗い工程と、第1すすぎ工程と、第2すすぎ工程と、脱水工程とを実行する。即ち、すすぎ工程は、少なくとも第1すすぎ工程と、第1すすぎ工程の後に実行される第2すすぎ工程とを含む。洗い工程では洗剤が洗濯槽4に供給され、すすぎ工程では他の液剤や錠剤等が洗濯槽4に供給される。実施の形態において、錠剤Jは第1すすぎ工程、即ち最終すすぎ工程の1つ前の工程で洗濯槽4に供給される。即ち、第1すすぎ工程において、給水弁10bを開放して、錠剤J(固形剤)に対して給水を行う、後述する本給水ステップS34が行われる。柔軟剤も供給する場合には、柔軟剤は第2すすぎ工程、即ち最終すすぎ工程で洗濯槽4に供給される。 First, the flow of the entire sterilization course will be described with reference to FIG. 12A. As shown in FIG. 12A, in the sterilization course, the control unit C sequentially executes a washing process, a first rinsing process, a second rinsing process, and a dehydration process. That is, the rinsing step includes at least a first rinsing step and a second rinsing step performed after the first rinsing step. In the washing process, detergent is supplied to the washing tub 4, and in the rinsing process, other liquids, tablets, etc. are supplied to the washing tub 4. In the embodiment, the tablets J are supplied to the washing tub 4 in the first rinsing step, ie, one step before the final rinsing step. That is, in the first rinsing step, a main water supply step S34, which will be described later, is performed in which the water supply valve 10b is opened and water is supplied to the tablet J (solid dosage form). If a softener is also supplied, the softener is supplied to the washing tub 4 in the second or final rinse step.
 まず、事前準備として、ユーザは、手動投入ユニット6に1回の除菌コースのための洗剤及び1つの錠剤Jを投入する。洗剤は投入口65aを通じて洗剤ケース60に投入される。錠剤Jは縦置きの姿勢で投入口63aに投入される。柔軟剤を使用する場合、ユーザは、自動投入ユニット7のタンク71に柔軟剤が収容されていることを確認し、残量が少ない場合にはタンク71に柔軟剤を補充する。 First, as a preliminary preparation, the user inputs detergent and one tablet J for one sterilization course into the manual input unit 6. Detergent is introduced into the detergent case 60 through the inlet 65a. The tablet J is placed into the slot 63a in a vertical position. When using the softener, the user confirms that the softener is stored in the tank 71 of the automatic dosing unit 7, and replenishes the tank 71 with the softener if the remaining amount is low.
 洗剤も自動投入ユニット7によって自動投入されてもよい。洗剤を自動投入する場合、ユーザは、自動投入ユニット7のタンク70に洗剤が収容されていることを確認し、残量が少ない場合にはタンク70に洗剤を補充する。 The detergent may also be automatically dispensed by the automatic dispenser unit 7. When automatically dispensing detergent, the user confirms that the detergent is stored in the tank 70 of the automatic dispensing unit 7, and replenishes the tank 70 with detergent if the remaining amount is low.
 以下、除菌コースを構成する各工程における処理の流れを詳細に説明する。 Hereinafter, the flow of processing in each step constituting the sterilization course will be explained in detail.
 <洗い工程>
 図12B、図13及び図14を参照して、洗い工程の処理の流れを説明する。まず、図12B、図13及び図14に示すように、制御部Cは、洗い工程の給水量Q1を決定する(ステップS10)。具体的には、制御部Cは、重量センサ26で検知された洗濯槽4内の洗濯物の重量を取得し、取得した重量に応じて、給水量Q1を決定する。
<Washing process>
The flow of the washing process will be described with reference to FIGS. 12B, 13, and 14. First, as shown in FIGS. 12B, 13, and 14, the control unit C determines the water supply amount Q1 for the washing process (step S10). Specifically, the control unit C acquires the weight of the laundry in the washing tub 4 detected by the weight sensor 26, and determines the water supply amount Q1 according to the acquired weight.
 続いて、制御部Cは、給水弁10aを開放して経路F1に所定量の水を給水する(ステップS11)。水は経路F1を通じて、洗剤ケース60に流入し、洗剤ケース60に収容されている洗剤とともに洗濯槽4に供給される。 Next, the control unit C opens the water supply valve 10a and supplies a predetermined amount of water to the path F1 (step S11). Water flows into the detergent case 60 through the path F1, and is supplied to the washing tub 4 together with the detergent contained in the detergent case 60.
 続いて、制御部Cは、洗濯槽4の水位が給水量Q1に応じた洗い水位Y1以上であるか否かを判定する(ステップS12)。具体的には、制御部Cは、水位センサ25で検知された水位を取得し、取得した水位と洗い水位Y1とを比較して判定する。 Subsequently, the control unit C determines whether the water level of the washing tub 4 is equal to or higher than the washing water level Y1 according to the water supply amount Q1 (step S12). Specifically, the control unit C acquires the water level detected by the water level sensor 25, and compares the acquired water level with the washing water level Y1 to make the determination.
 洗濯槽4の水位が洗い水位Y1より小さい場合(ステップS12でNO)、処理はステップS11に戻る。 If the water level in the washing tub 4 is lower than the washing water level Y1 (NO in step S12), the process returns to step S11.
 洗濯槽4の水位が洗い水位Y1以上である場合(ステップS12でYES)、制御部Cは給水弁10aを閉止する(ステップS13)。 If the water level of the washing tub 4 is equal to or higher than the wash water level Y1 (YES in step S12), the control unit C closes the water supply valve 10a (step S13).
 制御部Cは、ステップS12の処理を実行する代わりに、給水量Q1に応じた給水時間を決定し、給水弁10aを開放して、決定した給水時間が経過するまで給水を継続してもよい。 Instead of executing the process of step S12, the control unit C may determine the water supply time according to the water supply amount Q1, open the water supply valve 10a, and continue water supply until the determined water supply time has elapsed. .
 続いて、制御部Cは、洗濯槽4の撹拌機構8を作動させて洗濯物の洗い撹拌を実行する(ステップS14)。具体的には、制御部Cは、撹拌機構8に反転動作を実行させて洗い撹拌を実行する。洗い撹拌は、所定時間にわたって継続される。洗い撹拌は、所定の反転回数を達成するまで継続されてもよい。したがって、洗濯機1は、洗い工程において、給水及び撹拌を行うことで洗剤を洗濯槽4に供給して洗濯物を洗浄できる。 Next, the control unit C operates the stirring mechanism 8 of the washing tub 4 to wash and stir the laundry (step S14). Specifically, the control unit C causes the stirring mechanism 8 to perform a reversing operation to perform washing and stirring. Washing and stirring is continued for a predetermined period of time. Washing and stirring may be continued until a predetermined number of inversions is achieved. Therefore, in the washing process, the washing machine 1 can supply detergent to the washing tub 4 and wash the laundry by supplying water and stirring.
 制御部Cは、洗い撹拌において、給水弁10aを開放して追加の給水を行ってもよい。 The control unit C may open the water supply valve 10a to supply additional water during washing and agitation.
 次に、第1すすぎ工程における処理の流れを説明する。第1すすぎ工程は、準備、洗剤すすぎステップ、除菌ステップ及び錠剤すすぎステップを含む。以下、順に説明する。 Next, the flow of processing in the first rinsing step will be explained. The first rinsing step includes a preparation, a detergent rinsing step, a sterilization step and a tablet rinsing step. Below, they will be explained in order.
 <第1すすぎ工程:準備>
 まず、図12C、図13及び図14に示すように、制御部Cは、第1すすぎ工程の準備(ステップS15~S17)を実行する。
<First rinsing step: Preparation>
First, as shown in FIGS. 12C, 13, and 14, the control unit C executes preparation for the first rinsing step (steps S15 to S17).
 まず、制御部Cは、排水弁9を開放して所定量の水及び洗剤を排水する(ステップS15)。 First, the control unit C opens the drain valve 9 to drain a predetermined amount of water and detergent (step S15).
 続いて、制御部Cは、洗濯槽4の水位が最低水位Y0以下であるか否かを判定する(ステップS16)。具体的には、制御部Cは、水位センサ25で検知された水位を取得し、水位と最低水位Y0とを比較して判定する。図15に示すように、最低水位Y0とは、洗濯槽4の最高水位の10%以下の水位である。また、洗濯槽4に水が収容されていない状態における水位を最低水位Y0としてもよい。 Subsequently, the control unit C determines whether the water level of the washing tub 4 is below the minimum water level Y0 (step S16). Specifically, the control unit C acquires the water level detected by the water level sensor 25, and compares the water level with the lowest water level Y0 to make the determination. As shown in FIG. 15, the lowest water level Y0 is a water level that is 10% or less of the highest water level of the washing tub 4. Further, the water level in a state where no water is stored in the washing tub 4 may be set as the lowest water level Y0.
 洗濯槽4の水位が最低水位Y0より大きい場合(ステップS16でNO)、処理はステップS15に戻る。 If the water level of the washing tub 4 is higher than the lowest water level Y0 (NO in step S16), the process returns to step S15.
 洗濯槽4の水位が最低水位Y0以下である場合(ステップS16でYES)、制御部Cは排水弁9を閉止する(ステップS17)。ここで、制御部Cは中間脱水も実行してもよい。 If the water level of the washing tub 4 is below the minimum water level Y0 (YES in step S16), the control unit C closes the drain valve 9 (step S17). Here, the control unit C may also perform intermediate dehydration.
 <第1すすぎ工程:洗剤すすぎステップ>
 続いて、図12D、図13及び図14に示すように、制御部Cは、第1すすぎ工程の洗剤すすぎステップ(ステップS20~S27)を実行する。洗剤すすぎステップは、洗い工程において洗濯槽4に投入された洗剤を洗濯物からすすぐために実行される。
<First rinsing step: detergent rinsing step>
Subsequently, as shown in FIGS. 12D, 13, and 14, the control unit C executes the detergent rinsing step (steps S20 to S27) of the first rinsing process. The detergent rinsing step is performed to rinse the laundry from the detergent put into the washing tub 4 during the washing process.
 まず、制御部Cは給水弁10aを開放して経路F1に所定量の水を給水する(ステップS20)。水は経路F1を通じて、洗剤ケース60を経由して洗濯槽4に供給される。事前準備で洗剤ケース60に投入された洗剤は洗い工程で使用されるため、ステップS20において、水は空の洗剤ケース60を経由して洗濯槽4に供給される。 First, the control unit C opens the water supply valve 10a and supplies a predetermined amount of water to the path F1 (step S20). Water is supplied to the washing tub 4 via the detergent case 60 through the path F1. Since the detergent put into the detergent case 60 in advance is used in the washing process, water is supplied to the washing tub 4 via the empty detergent case 60 in step S20.
 続いて、制御部Cは、洗濯槽4の水位が洗剤すすぎ水位Y2以上であるか否かを判定する(ステップS21)。具体的には、制御部Cは、水位センサ25で検知された水位を取得し、水位と洗剤すすぎ水位Y2とを比較して判定する。図15に示すように、洗剤すすぎ水位Y2は、洗濯物が水に浸るために必要であると想定される水位である。制御部Cは、重量センサ26で検知された洗濯槽4内の洗濯物の重量を取得し、取得した重量に応じて、洗剤すすぎ水位Y2を決定してもよい。例えば、洗剤すすぎ水位Y2は、制御部Cが取得した洗濯物の重量に応じて、浴比が10L/kgとなる水位である。なお、洗剤すすぎ水位Y2は、少なくとも洗濯槽4に水が収容されていない状態における水位より高い水位である。 Next, the control unit C determines whether the water level in the washing tub 4 is equal to or higher than the detergent rinse water level Y2 (step S21). Specifically, the control unit C acquires the water level detected by the water level sensor 25, and compares the water level with the detergent rinse water level Y2 to make the determination. As shown in FIG. 15, the detergent rinse water level Y2 is the water level that is assumed to be necessary for the laundry to be immersed in water. The control unit C may acquire the weight of the laundry in the washing tub 4 detected by the weight sensor 26, and determine the detergent rinse water level Y2 according to the acquired weight. For example, the detergent rinse water level Y2 is a water level at which the bath ratio is 10 L/kg according to the weight of the laundry acquired by the control unit C. Note that the detergent rinse water level Y2 is at least higher than the water level in a state where no water is stored in the washing tub 4.
 洗濯槽4の水位が洗剤すすぎ水位Y2より小さい場合(ステップS21でNO)、処理はステップS20に戻る。 If the water level in the washing tub 4 is lower than the detergent rinse water level Y2 (NO in step S21), the process returns to step S20.
 洗濯槽4の水位が洗剤すすぎ水位Y2以上である場合(ステップS21でYES)、制御部Cは給水弁10aを閉止する(ステップS22)。したがって、洗濯槽4には洗剤すすぎ水位Y2以上の水が収容されている。 If the water level in the washing tub 4 is equal to or higher than the detergent rinse water level Y2 (YES in step S21), the control unit C closes the water supply valve 10a (step S22). Therefore, the washing tub 4 contains water at a detergent rinse level Y2 or higher.
 続いて、制御部Cは、給水弁10bを開放して経路F2に少量の給水量を給水する(以降、予備給水ステップS23)。このような動作によって錠剤Jが湿潤されて溶けやすくなる。水は経路F2を通じて錠剤ケース63に流入し、図11に示すように錠剤Jに間接的に当たる。少量の給水量とは、錠剤Jの表面を湿潤させる一方、錠剤Jを溶かして錠剤ケース63から流出させるには足りない給水量を意味する。 Subsequently, the control unit C opens the water supply valve 10b and supplies a small amount of water to the path F2 (hereinafter, preliminary water supply step S23). This operation moistens the tablet J and makes it easier to dissolve. Water flows into the tablet case 63 through the path F2 and indirectly hits the tablets J as shown in FIG. The small amount of water supplied means that while the surface of the tablet J is moistened, the amount of water supplied is insufficient to dissolve the tablet J and cause it to flow out of the tablet case 63.
 ここで、予備給水ステップS23における給水量は、後続の本給水ステップS34の給水量より少ない。予備給水ステップS23において、給水弁10bから供給される少量の給水量は、400mL以上2500mL以下の給水であってもよく、望ましくは、400mL以上1250mL以下の給水である。給水弁10bによって供給される水の流量は5L/分以上15L/分以下であってもよい。給水弁10bから給水される水の内の約15%が錠剤ケース63に配分され、例えば、50mL以上200mL以下の水が錠剤ケース63に流入する。例えば、12L/分で、5秒間給水して、給水弁10bから1000mLの水が給水されると、140mLの水が錠剤ケース63に流入する。給水時間は10秒未満であってもよく、望ましくは、略5秒であってもよい。 Here, the amount of water supplied in the preliminary water supply step S23 is smaller than the amount of water supplied in the subsequent main water supply step S34. In the preliminary water supply step S23, the small amount of water supplied from the water supply valve 10b may be 400 mL or more and 2500 mL or less, preferably 400 mL or more and 1250 mL or less. The flow rate of water supplied by the water supply valve 10b may be 5 L/min or more and 15 L/min or less. Approximately 15% of the water supplied from the water supply valve 10b is distributed to the tablet case 63, and for example, 50 mL or more and 200 mL or less of water flows into the tablet case 63. For example, when water is supplied at 12 L/min for 5 seconds and 1000 mL of water is supplied from the water supply valve 10b, 140 mL of water flows into the tablet case 63. The water supply time may be less than 10 seconds, preferably approximately 5 seconds.
 洗濯槽4の水位が洗剤すすぎ水位Y2より大きい状態で予備給水ステップS23を行うことによって、錠剤Jが溶解して洗濯槽4に流入した場合においても、錠剤Jが洗濯物に付着することを抑制できる。そのため、洗濯機1は、洗濯物の色落ちを抑制できる。 By performing the preliminary water supply step S23 when the water level in the washing tub 4 is higher than the detergent rinse water level Y2, even if the tablets J dissolve and flow into the washing tub 4, the tablets J are prevented from adhering to the laundry. can. Therefore, the washing machine 1 can suppress discoloration of laundry.
 続いて、制御部Cは、給水弁10bを閉止して待機時間を開始する(ステップS24)。待機時間は、給水弁10bから経路F2への給水は停止している時間である。例えば、待機時間は、20秒以上である。一方で、制御部Cは、待機時間において、給水弁10aからの給水、排水、撹拌等の他の操作を実行する。 Subsequently, the control unit C closes the water supply valve 10b and starts a standby time (step S24). The standby time is the time during which the water supply from the water supply valve 10b to the route F2 is stopped. For example, the waiting time is 20 seconds or more. On the other hand, during the standby time, the control unit C performs other operations such as supplying water from the water supply valve 10a, discharging water, and stirring.
 待機時間を設けることで、洗濯機1は、予備給水ステップS23において湿潤された錠剤Jが発泡する時間を確保できる。また、洗濯機1は、予備給水された水が、錠剤Jの表面からさらに内部に浸透する時間を確保できる。発泡した錠剤Jまたは水が内部に浸透した錠剤Jは、水に溶けやすくなっている。溶けやすい錠剤Jに対して本給水ステップS34を行うことで、予備給水ステップS23を行わずに本給水ステップS34を行う場合と比較して、錠剤Jを容易に溶かし切ることができる。 By providing a standby time, the washing machine 1 can secure time for the tablets J moistened in the preliminary water supply step S23 to foam. Further, the washing machine 1 can ensure time for the pre-supplied water to further penetrate into the inside of the tablet J from the surface thereof. The foamed tablet J or the tablet J in which water has penetrated into the inside is easily dissolved in water. By performing the main water supply step S34 on the easily soluble tablet J, the tablet J can be easily dissolved, compared to the case where the main water supply step S34 is performed without performing the preliminary water supply step S23.
 続いて、制御部Cは、排水弁9を開放して所定量の水及び洗剤を排水する(ステップS25)。 Subsequently, the control unit C opens the drain valve 9 to drain a predetermined amount of water and detergent (step S25).
 続いて、制御部Cは、洗濯槽4の水位が最低水位Y0以下であるか否かを判定する(ステップS26)。具体的には、制御部Cは、水位センサ25で検知された水位を取得し、水位と最低水位Y0とを比較して判定する。 Subsequently, the control unit C determines whether the water level of the washing tub 4 is below the minimum water level Y0 (step S26). Specifically, the control unit C acquires the water level detected by the water level sensor 25, and compares the water level with the lowest water level Y0 to make the determination.
 洗濯槽4の水位が最低水位Y0より大きい場合(ステップS26でNO)、処理はステップS25に戻る。 If the water level of the washing tub 4 is higher than the lowest water level Y0 (NO in step S26), the process returns to step S25.
 洗濯槽4の水位が最低水位Y0以下である場合(ステップS26でYES)、制御部Cは排水弁9を閉止して(ステップS27)、洗剤すすぎステップを終了する。したがって、洗剤すすぎステップにおいて、洗剤を洗濯物からより確実にすすぎ落とすとともに、錠剤Jを湿潤させて溶けやすくすることができる。 If the water level in the washing tub 4 is below the minimum water level Y0 (YES in step S26), the control unit C closes the drain valve 9 (step S27) and ends the detergent rinsing step. Therefore, in the detergent rinsing step, the detergent can be more reliably rinsed off from the laundry, and the tablets J can be moistened and easily dissolved.
 <第1すすぎ工程:除菌ステップ>
 続いて、図12E、図13及び図14に示すように、制御部Cは、第1すすぎ工程の除菌ステップ(ステップS30~S42)を実行する。除菌ステップは、錠剤ケース63に投入された錠剤Jを洗濯槽4に供給し、洗濯物を除菌するために実行される。
<First rinsing step: Sterilization step>
Subsequently, as shown in FIGS. 12E, 13, and 14, the control unit C executes the sterilization step (steps S30 to S42) of the first rinsing process. The sterilization step is executed to supply the tablets J placed in the tablet case 63 to the washing tub 4 and to sterilize the laundry.
 まず、制御部Cは給水弁10aを開放して経路F1に所定量の水を給水する(ステップS30)。水は経路F1を通じて、空の洗剤ケース60を経由して洗濯槽4に供給される。 First, the control unit C opens the water supply valve 10a and supplies a predetermined amount of water to the path F1 (step S30). Water is supplied to the washing tub 4 via the empty detergent case 60 through the path F1.
 続いて、制御部Cは、洗濯槽4の水位が除菌前水位Y3以上であるか否かを判定する(ステップS31)。具体的には、制御部Cは、水位センサ25で検知された水位を取得し、水位と除菌前水位Y3とを比較して判定する。除菌前水位Y3は、洗濯物が水に浸るために必要であると想定される水位以上である。除菌前水位Y3は、制御部Cが取得した洗濯物の重量に応じて、浴比が10L/kg以上となる水位である。実施の形態において、除菌前水位Y3は、洗い水位Y1及び洗剤すすぎ水位Y2より高い。なお、除菌前水位Y3は、洗い水位Y1または洗剤すすぎ水位Y2と等しくてもよい。なお、除菌前水位Y3は、少なくとも洗濯槽4に水が収容されていない状態における水位より高い水位である。 Subsequently, the control unit C determines whether the water level of the washing tub 4 is equal to or higher than the pre-sterilization water level Y3 (step S31). Specifically, the control unit C acquires the water level detected by the water level sensor 25, and compares the water level with the pre-sterilization water level Y3 to make the determination. The pre-sterilization water level Y3 is higher than the water level that is assumed to be necessary for the laundry to be immersed in water. The pre-sterilization water level Y3 is a water level at which the bath ratio is 10 L/kg or more, depending on the weight of the laundry acquired by the control unit C. In the embodiment, the pre-sterilization water level Y3 is higher than the washing water level Y1 and the detergent rinse water level Y2. Note that the pre-sterilization water level Y3 may be equal to the washing water level Y1 or the detergent rinsing water level Y2. Note that the pre-sterilization water level Y3 is at least higher than the water level in a state where no water is stored in the washing tub 4.
 洗濯槽4の水位が除菌前水位Y3より小さい場合(ステップS31でNO)、処理はステップS30に戻る。 If the water level in the washing tub 4 is lower than the pre-sterilization water level Y3 (NO in step S31), the process returns to step S30.
 洗濯槽4の水位が除菌前水位Y3以上である場合(ステップS31でYES)、制御部Cは給水弁10aを閉止する(ステップS32)。 When the water level of the washing tub 4 is equal to or higher than the pre-sterilization water level Y3 (YES in step S31), the control unit C closes the water supply valve 10a (step S32).
 続いて、制御部Cは、待機時間が経過したか否かを判定する(ステップS33)。 Subsequently, the control unit C determines whether the standby time has elapsed (step S33).
 待機時間が経過していない場合(ステップS33でNO)、所定時間、例えば5秒経過後に再度ステップS33を実行する。 If the standby time has not elapsed (NO in step S33), step S33 is executed again after a predetermined period of time, for example, 5 seconds has elapsed.
 待機時間が経過した場合(ステップS33でYES)、制御部Cは本給水ステップS34を実行する。本給水ステップS34では、制御部Cは、給水弁10aを閉じた状態で、給水弁10bを開放して経路F2に給水する。水は経路F2を通じて錠剤ケース63に流入し、図11に示すように錠剤Jに間接的に当たる。予備給水ステップS23より給水量が多いため、錠剤Jは溶解される。溶けた錠剤Jは、水とともにメッシュ82を通じて洗濯槽4に供給される。 If the standby time has elapsed (YES in step S33), the control unit C executes the main water supply step S34. In the main water supply step S34, the control unit C closes the water supply valve 10a, opens the water supply valve 10b, and supplies water to the path F2. Water flows into the tablet case 63 through the path F2 and indirectly hits the tablets J as shown in FIG. Since the amount of water supplied is larger than that in the preliminary water supply step S23, the tablet J is dissolved. The melted tablets J are supplied to the washing tub 4 through the mesh 82 along with water.
 本給水ステップS34における給水量は、30Lの給水であってもよく、120秒以上の給水であってもよく、例えば、予備給水ステップS23における給水量の30倍である。実施の形態では、給水弁10bの開放によって供給される水の流量は、給水弁10aの開放によって供給される水の流量よりも小さい。このような構成によって、予め決められた給水量に対しての給水時間を長くすることができる。そのため、錠剤Jに水が当たる時間を長くして、錠剤Jを容易に溶かすことができる。なお、給水弁10bの開放によって供給される水の流量は、給水弁10aの開放によって供給される水の流量より大きくてもよい。 The amount of water supplied in the main water supply step S34 may be 30 L of water, or may be supplied for 120 seconds or more, and is, for example, 30 times the amount of water supplied in the preliminary water supply step S23. In the embodiment, the flow rate of water supplied by opening the water supply valve 10b is smaller than the flow rate of water supplied by opening the water supply valve 10a. With such a configuration, it is possible to lengthen the water supply time for a predetermined amount of water supply. Therefore, the time period during which the tablet J is exposed to water can be increased, and the tablet J can be easily dissolved. Note that the flow rate of water supplied by opening the water supply valve 10b may be larger than the flow rate of water supplied by opening the water supply valve 10a.
 本給水ステップS34において、制御部Cは、洗濯槽4の撹拌機構8を作動させて洗濯物の本給水撹拌をさらに実行する。具体的には、制御部Cは、撹拌機構8に反転動作を実行させて本給水撹拌を実行する。なお、本給水撹拌は、本開示の第1撹拌の一例に相当する。また、実施の形態では、制御部Cは、本給水ステップS34の終了後においても、所定時間にわたって本給水撹拌を継続する。このような動作によって、錠剤Jが洗濯物に均一に作用し、広範囲にわたって除菌効果を及ぼすことができる。 In the main water supply step S34, the control unit C operates the stirring mechanism 8 of the washing tub 4 to further perform the main water supply stirring of the laundry. Specifically, the control unit C causes the stirring mechanism 8 to perform a reversal operation to perform the main water supply stirring. Note that the main water supply stirring corresponds to an example of the first stirring of the present disclosure. Furthermore, in the embodiment, the control unit C continues the main water supply stirring for a predetermined period of time even after the main water supply step S34 ends. By such an operation, the tablets J can act uniformly on the laundry and exert a sterilization effect over a wide range.
 続いて、制御部Cは、洗濯槽4の水位が除菌中水位Y4以上であるか否かを判定する(ステップS35)。具体的には、制御部Cは、水位センサ25で検知された水位を取得し、水位と除菌中水位Y4とを比較して判定する。図13及び図15に示すように、除菌中水位Y4は、洗い水位Y1、洗剤すすぎ水位Y2、及び除菌前水位Y3より高い。このような動作によって、錠剤Jの溶解物は洗濯槽4に供給される水中に浮遊し、錠剤Jの溶解物が洗濯物に付着することを抑制できる。錠剤Jの溶解物が洗濯物に長時間付着することを抑制することで、洗濯物の傷みや色落ちを抑制することができる。また、洗濯槽4において、錠剤Jの溶解物に対する水の量を増加させることで、錠剤Jが溶けやすくなる。 Subsequently, the control unit C determines whether the water level of the washing tub 4 is equal to or higher than the sterilization water level Y4 (step S35). Specifically, the control unit C obtains the water level detected by the water level sensor 25, and compares the water level with the sterilization water level Y4 to make the determination. As shown in FIGS. 13 and 15, the sterilization water level Y4 is higher than the washing water level Y1, the detergent rinsing water level Y2, and the pre-sterilization water level Y3. By such an operation, the dissolved substances of the tablets J float in the water supplied to the washing tub 4, and it is possible to suppress the dissolved substances of the tablets J from adhering to the laundry. By preventing the dissolved substance of Tablet J from adhering to the laundry for a long period of time, it is possible to suppress damage and discoloration of the laundry. Furthermore, by increasing the amount of water relative to the dissolved material of the tablets J in the washing tub 4, the tablets J can be easily dissolved.
 洗濯槽4の水位が除菌中水位Y4より小さい場合(ステップS35でNO)、制御部Cは、給水弁10bを通じて少量の追加給水を行って、再度ステップS35を実行する。少量の追加給水とは、例えば、0.3Lの給水である。 If the water level of the washing tub 4 is lower than the sterilization water level Y4 (NO in step S35), the control unit C supplies a small amount of additional water through the water supply valve 10b and executes step S35 again. The small amount of additional water supply is, for example, 0.3L of water supply.
 洗濯槽4の水位が除菌中水位Y4以上である場合(ステップS35でYES)、制御部Cは給水弁10bを閉止する(ステップS36)。 When the water level of the washing tub 4 is equal to or higher than the sterilization water level Y4 (YES in step S35), the control unit C closes the water supply valve 10b (step S36).
 続いて、制御部Cは、給水条件が、錠剤Jが溶けにくい条件であるか否かを判定し、錠剤Jが溶けにくい条件である場合に、本給水ステップS34後に追加の工程(ステップS37~S42)を実行する。錠剤Jが溶けにくい条件として、給水流量が大きい場合、給水水温が低い場合が挙げられる。 Subsequently, the control unit C determines whether or not the water supply conditions are such that the tablets J are difficult to dissolve. If the water supply conditions are such that the tablets J are difficult to dissolve, the control unit C performs additional steps (steps S37 to S34) after the main water supply step S34. S42) is executed. Conditions under which the tablet J is difficult to dissolve include a case where the water supply flow rate is large and a case where the water supply water temperature is low.
 そこで、まず、制御部Cは、給水弁10bを通じて供給される水の流量を決定する(ステップS37)。具体的には、制御部Cは、水位センサ25が検知する水位の増加を、水位の増加にかかった時間で除算して給水流量を算出する。 Therefore, first, the control unit C determines the flow rate of water supplied through the water supply valve 10b (step S37). Specifically, the control unit C calculates the water supply flow rate by dividing the increase in the water level detected by the water level sensor 25 by the time taken for the increase in the water level.
 続いて、制御部Cは、算出された給水流量が所定流量より大きいか否かを判定する(ステップS38)。 Subsequently, the control unit C determines whether the calculated water supply flow rate is larger than a predetermined flow rate (step S38).
 給水流量が所定流量より大きい場合(ステップS38でYES)、制御部Cは、錠剤ケース63への追加給水を実行する(ステップS39)。具体的には、制御部Cは、排水弁9を開放して少量の水を排水した後、排水弁9を閉じて、給水弁10bを開放して少量の水を錠剤ケース63に給水する。少量の追加給水とは、例えば、5Lの給水である。このような動作によって、洗濯槽4の水位が過剰に上昇することを抑制しつつ、錠剤ケース63における錠剤Jの溶け残りを抑制できる。 If the water supply flow rate is larger than the predetermined flow rate (YES in step S38), the control unit C executes additional water supply to the tablet case 63 (step S39). Specifically, the control unit C opens the drain valve 9 to drain a small amount of water, then closes the drain valve 9 and opens the water supply valve 10b to supply a small amount of water to the tablet case 63. The small amount of additional water supply is, for example, 5L of water supply. By such an operation, it is possible to prevent the water level in the washing tub 4 from rising excessively and to prevent the tablets J from remaining undissolved in the tablet case 63.
 給水流量が所定流量より小さい場合(ステップS38でNO)、ステップS40に進む。 If the water supply flow rate is smaller than the predetermined flow rate (NO in step S38), the process proceeds to step S40.
 続いて、制御部Cは、洗濯機1に供給される水の水温を決定する(ステップS40)。具体的には、制御部Cは、水温センサ27が検知する給水水温を取得する。 Subsequently, the control unit C determines the temperature of water supplied to the washing machine 1 (step S40). Specifically, the control unit C acquires the water supply temperature detected by the water temperature sensor 27.
 続いて、制御部Cは、給水水温が所定水温より低いか否かを判定する(ステップS41)。所定水温は例えば10°Cである。 Next, the control unit C determines whether the water supply temperature is lower than a predetermined water temperature (step S41). The predetermined water temperature is, for example, 10°C.
 給水水温が10°Cより低い場合(ステップS41でYES)、制御部Cは、ヒータ28を作動させた状態で、洗濯槽4の撹拌機構8を作動させて洗濯物の追加撹拌を実行する(ステップS42)。具体的には、ヒータ28が加熱を実行している状態で、制御部Cは、撹拌機構8に反転動作を実行させて追加撹拌を実行する。なお、この追加撹拌は、本開示の第2撹拌の一例に相当する。 If the water supply temperature is lower than 10°C (YES in step S41), the control unit C operates the stirring mechanism 8 of the washing tub 4 to perform additional stirring of the laundry while the heater 28 is activated. Step S42). Specifically, while the heater 28 is performing heating, the control unit C causes the stirring mechanism 8 to perform a reversal operation to perform additional stirring. Note that this additional stirring corresponds to an example of the second stirring of the present disclosure.
 また、ステップS42では、制御部Cは、さらに錠剤ケース63への追加給水(ステップS39)を実行する。なお、給水水温が10°Cより低い場合(ステップS41でYES)かつ給水流量が所定流量より小さい場合に(ステップS38でNO)、制御部Cは、錠剤ケース63への追加給水(ステップS39)を実行してもよい。 In addition, in step S42, the control unit C further performs additional water supply to the tablet case 63 (step S39). Note that if the water supply temperature is lower than 10°C (YES in step S41) and the water supply flow rate is smaller than the predetermined flow rate (NO in step S38), the control unit C supplies additional water to the tablet case 63 (step S39). may be executed.
 給水水温が10°Cより高い場合(ステップS41でNO)、制御部Cは、除菌ステップを終了する。したがって、除菌ステップにおいて、給水を行うことで錠剤Jを溶かして洗濯槽4に供給し、洗濯槽4内で溶け切っていない錠剤Jが洗濯物に付着することを抑制しつつ、洗濯物を除菌することができる。 If the water supply temperature is higher than 10°C (NO in step S41), the control unit C ends the sterilization step. Therefore, in the sterilization step, water is supplied to dissolve the tablets J and supply them to the washing tub 4, thereby preventing the undissolved tablets J from adhering to the laundry in the washing tub 4, and washing the laundry. Can be sterilized.
 <第1すすぎ工程:錠剤すすぎステップ>
 続いて、図12F、図13及び図14に示すように、制御部Cは、第1すすぎ工程の錠剤すすぎステップ(ステップS50~S53)を実行する。錠剤すすぎステップは、除菌ステップにおいて洗濯槽4に投入された錠剤Jをすすぐために実行される。
<First rinsing step: Tablet rinsing step>
Subsequently, as shown in FIGS. 12F, 13, and 14, the control unit C executes the tablet rinsing step (steps S50 to S53) of the first rinsing process. The tablet rinsing step is executed to rinse the tablets J put into the washing tub 4 in the sterilization step.
 制御部Cは、排水弁9を開放して所定量の水及び錠剤Jの溶解物を排水する(ステップS50)。 The control unit C opens the drain valve 9 to drain a predetermined amount of water and the dissolved substance of the tablet J (step S50).
 続いて、制御部Cは、洗濯槽4の水位が錠剤すすぎ水位Y5以下か否かを判定する(ステップS51)。錠剤すすぎ水位Y5は最低水位Y0より高い。 Subsequently, the control unit C determines whether the water level in the washing tub 4 is equal to or lower than the tablet rinsing water level Y5 (step S51). The tablet rinsing water level Y5 is higher than the lowest water level Y0.
 洗濯槽4の水位が錠剤すすぎ水位Y5より大きい場合(ステップS51でNO)、処理はステップS50に戻る。 If the water level in the washing tub 4 is higher than the tablet rinsing water level Y5 (NO in step S51), the process returns to step S50.
 洗濯槽4の水位が錠剤すすぎ水位Y5以下である場合(ステップS51でYES)、制御部Cは排水弁9を閉止する(ステップS52)。この状態において、洗濯槽4には最低水位Y0より高い水位の一定の水が保持されていることが想定される。 If the water level in the washing tub 4 is below the tablet rinsing water level Y5 (YES in step S51), the control unit C closes the drain valve 9 (step S52). In this state, it is assumed that the washing tub 4 holds a constant water level higher than the lowest water level Y0.
 続いて、制御部Cは、給水弁10bを開放して経路F2に所定量の水を給水して、給水弁10bを閉止する(ステップS53)。水が洗濯槽4に供給されるため、衣類等の洗濯物に残っている錠剤Jの成分をすすぐことができる。また、水が経路F2を通じて供給されるため、水は錠剤ケース63に流入し、溶け残っている錠剤Jをさらに洗い出すことができる。 Subsequently, the control unit C opens the water supply valve 10b, supplies a predetermined amount of water to the path F2, and closes the water supply valve 10b (step S53). Since water is supplied to the washing tub 4, the components of the tablets J remaining in the laundry such as clothes can be rinsed away. Further, since water is supplied through the path F2, the water flows into the tablet case 63, and the undissolved tablets J can be further washed out.
 <第2すすぎ工程>
 続いて、図12G、図13及び図14に示すように、第2すすぎ工程において、制御部Cは、排水弁9を開放して所定量の水を排水する(ステップS54)。ここで、制御部Cは中間脱水も実行してもよい。
<Second rinsing step>
Subsequently, as shown in FIGS. 12G, 13, and 14, in the second rinsing step, the control unit C opens the drain valve 9 to drain a predetermined amount of water (step S54). Here, the control unit C may also perform intermediate dehydration.
 続いて、制御部Cは、洗濯槽4の水位が最低水位Y0以下か否かを判定する(ステップS55)。 Subsequently, the control unit C determines whether the water level of the washing tub 4 is below the minimum water level Y0 (step S55).
 洗濯槽4の水位が最低水位Y0より大きい場合(ステップS55でNO)、処理はステップS54に戻る。 If the water level of the washing tub 4 is higher than the lowest water level Y0 (NO in step S55), the process returns to step S54.
 洗濯槽4の水位が最低水位Y0以下である場合(ステップS55でYES)、制御部Cは排水弁9を閉止する(ステップS56)。これにより、洗濯機1は、錠剤Jを洗濯物からより確実にすすぎ落として、錠剤Jを含む水を洗濯槽4から排出できる。 If the water level of the washing tub 4 is below the minimum water level Y0 (YES in step S55), the control unit C closes the drain valve 9 (step S56). Thereby, the washing machine 1 can more reliably rinse the tablets J from the laundry and discharge the water containing the tablets J from the washing tub 4.
 続いて、制御部Cは、間欠的に給水弁10bを複数回開放して経路F2に給水する(ステップS60)。具体的には、制御部Cは、一定期間にわたって、一定の間隔で給水弁10bの開閉を繰り返して経路F2に給水する。このような動作によって、水は断続的に経路F2を通じて錠剤ケース63に流入し、流入する水の流量の変動によって錠剤ケース63の洗浄を促進することができる。 Subsequently, the control unit C intermittently opens the water supply valve 10b multiple times to supply water to the path F2 (step S60). Specifically, the control unit C repeatedly opens and closes the water supply valve 10b at regular intervals over a certain period of time to supply water to the path F2. With this operation, water intermittently flows into the tablet case 63 through the path F2, and cleaning of the tablet case 63 can be facilitated by varying the flow rate of the inflowing water.
 並行して、制御部Cは柔軟剤の供給を実行する。柔軟剤の供給は、手動投入ユニット6ではなく、自動投入ユニット7によって行われる。手動投入の柔軟剤ケース61は錠剤ケース63と経路F2を共用するため、手動投入ユニット6によって柔軟剤を供給しようとすると、柔軟剤と錠剤Jとを分けて供給することが難しく、柔軟剤と錠剤Jとが混ざる恐れがある。柔軟剤と錠剤Jとが混ざると、錠剤Jが理想の効果を発揮しにくくなる。一方で、柔軟剤と錠剤Jとの出し分けができると、錠剤Jを第1すすぎ工程で洗濯槽4に供給し、柔軟剤を最終すすぎ工程(即ち、第2すすぎ工程)で洗濯槽4に供給できる。第1すすぎ工程で錠剤Jを供給した後に第2すすぎ工程で洗濯物をすすぐことができるため、洗濯物に対する錠剤Jの付着をより一層抑制できる。柔軟剤を洗濯槽4に供給した直後に脱水工程に進むことができるため、供給後にすすぎ工程を設けた場合と比較して、洗濯物に付着した成分や香りが維持される。そのため、制御部Cは、自動投入ユニット7を作動させることによって柔軟剤の供給を行う。 In parallel, the control unit C executes the supply of softener. The supply of softener is performed not by the manual dosing unit 6 but by the automatic dosing unit 7. Since the manual feeding softener case 61 shares the path F2 with the tablet case 63, if you try to feed the softener using the manual feeding unit 6, it will be difficult to feed the softener and the tablets J separately. There is a risk of mixing with Tablet J. If the softener and tablet J are mixed, it becomes difficult for tablet J to exhibit its ideal effect. On the other hand, when the softener and tablets J can be dispensed separately, the tablets J are supplied to the washing tub 4 in the first rinsing process, and the softener is supplied to the washing tub 4 in the final rinsing process (i.e., the second rinsing process). Can be supplied. Since the laundry can be rinsed in the second rinsing step after the tablets J are supplied in the first rinsing step, adhesion of the tablets J to the laundry can be further suppressed. Since the dehydration process can proceed immediately after supplying the softener to the washing tub 4, the components and fragrance attached to the laundry are maintained, compared to a case where a rinsing process is provided after the supply. Therefore, the control unit C supplies the softener by operating the automatic dosing unit 7.
 続いて、制御部Cは、洗濯槽4の水位が最終すすぎ水位Y6以上であるか否かを判定する(ステップS61)。最終すすぎ水位Y6は除菌中水位Y4より低い。 Subsequently, the control unit C determines whether the water level of the washing tub 4 is equal to or higher than the final rinse water level Y6 (step S61). The final rinsing water level Y6 is lower than the sterilization water level Y4.
 洗濯槽4の水位が最終すすぎ水位Y6より小さい場合(ステップS61でNO)、制御部Cは給水弁10bを通じて少量の追加給水を行って、再度ステップS61を実行する。 If the water level of the washing tub 4 is lower than the final rinse water level Y6 (NO in step S61), the control unit C supplies a small amount of additional water through the water supply valve 10b and executes step S61 again.
 洗濯槽4の水位が錠剤すすぎ水位Y5以上である場合(ステップS61でYES)、制御部Cは給水弁10bを閉止する(ステップS62)。 If the water level in the washing tub 4 is equal to or higher than the tablet rinsing water level Y5 (YES in step S61), the control unit C closes the water supply valve 10b (step S62).
 続いて、制御部Cは、洗濯槽4の撹拌機構8を作動させて洗濯物の撹拌を実行する(ステップS63)。 Next, the control unit C operates the stirring mechanism 8 of the washing tub 4 to stir the laundry (step S63).
 <脱水工程>
 続いて、制御部Cは、脱水工程において、洗濯槽4の水を排水して、洗濯物の脱水を行う(ステップS70)。その後、制御部Cは除菌コースを終了する。
<Dehydration process>
Subsequently, in the dewatering process, the control unit C drains the water from the washing tub 4 and dehydrates the laundry (step S70). After that, the control unit C ends the sterilization course.

It is possible to suppress the effects of
 さらに、第1すすぎ工程で錠剤Jを供給した後に、錠剤すすぎ工程及び第2すすぎ工程を実行することで、錠剤Jが洗濯物に長時間付着することを抑制できる。そのため、洗濯機1は、錠剤Jの化学的作用によって、洗濯物が傷む、または洗濯物の色落ちが生じることを抑制できる。 Furthermore, by performing the tablet rinsing process and the second rinsing process after supplying the tablets J in the first rinsing process, it is possible to suppress the tablets J from adhering to the laundry for a long time. Therefore, the washing machine 1 can suppress damage to the laundry or discoloration of the laundry due to the chemical action of the tablets J.
 [効果]

Equipped with. The washing tub 4 is rotatably provided within the housing 2. The detergent case 60 stores detergent to be supplied to the washing tub 4. The tablet case 63 accommodates the tablets J supplied to the washing tub 4. The water supply valve 10a supplies water to the detergent case 60. The water supply valve 10b supplies water to the tablet case 63. The control unit C controls the water supply valve 10a and the water supply valve 10b. In the washing process, the control unit C opens the water supply valve 10a (step S11) and closes the water supply valve 10b (step S13). Further, the control unit C executes a main water supply step S34 in which water is supplied to the tablet J by opening the water supply valve 10b in the rinsing process after the washing process.
 このような構成によって、本実施の形態の洗濯機1は、洗剤ケース60への給水と、錠剤ケース63への給水を異なる工程において実行できる。そのため、洗剤と錠剤Jの溶解物とは、異なるタイミングにおいて洗濯槽4に供給される。したがって、洗剤と錠剤Jとが混ざることを抑制して錠剤Jの効果を高めることができる。即ち、本実施の形態の洗濯機1は、洗濯物に対する除菌性能を向上させることができる。 With such a configuration, the washing machine 1 of the present embodiment can supply water to the detergent case 60 and water to the tablet case 63 in different steps. Therefore, the detergent and the dissolved product of the tablets J are supplied to the washing tub 4 at different timings. Therefore, mixing of the detergent and the tablet J can be suppressed, and the effectiveness of the tablet J can be enhanced. That is, the washing machine 1 of this embodiment can improve the sterilization performance for laundry.

 このような構成によって、洗濯槽4に除菌前水位Y3の水を溜めた状態で錠剤Jを供給することができる。そのため、洗濯槽4における錠剤Jの濃度を適切な範囲内に抑えることができて、本実施の形態の洗濯機1は、錠剤成分が洗濯物に直接接触して洗濯物の脱色が生じることを抑制できる。 With such a configuration, the tablets J can be supplied while the washing tub 4 is filled with water at the pre-sterilization water level Y3. Therefore, the concentration of the tablets J in the washing tub 4 can be suppressed within an appropriate range, and the washing machine 1 of the present embodiment prevents the tablet components from coming into direct contact with the laundry and causing decolorization of the laundry. It can be suppressed.
 また、本実施の形態の洗濯機1において、除菌前水位Y3(所定量)は、洗濯槽4の水位が、洗濯槽4に収容された洗濯物が水没する水位、浴比が10L/kg以上となる水位、または、洗い工程と同水位(洗い水位Y1)となる量である。 In the washing machine 1 of the present embodiment, the pre-sterilization water level Y3 (predetermined amount) is such that the water level in the washing tub 4 is the water level at which the laundry stored in the washing tub 4 is submerged, and the bath ratio is 10 L/kg. This is the water level above or the same water level as in the washing process (washing water level Y1).
 このような構成によって、本実施の形態の洗濯機1は、錠剤成分が洗濯物に直接接触して洗濯物の脱色が生じることを抑制できる。 With such a configuration, the washing machine 1 of the present embodiment can suppress the decolorization of the laundry due to the tablet component coming into direct contact with the laundry.
 また、本実施の形態の洗濯機1は、洗濯槽4に収容された洗濯物を撹拌させる撹拌機構8をさらに有し、制御部Cは、撹拌機構8を駆動して本給水撹拌(第1撹拌)を実行している状態で、給水弁10bを開放する。 Further, the washing machine 1 of the present embodiment further includes an agitation mechanism 8 that agitates the laundry stored in the washing tub 4, and the control unit C drives the agitation mechanism 8 to perform main water supply agitation (first water supply agitation). While stirring) is being performed, the water supply valve 10b is opened.
