Description

本発明は、水槽内に回転自在に配設された回転ドラム内に洗濯物を収容して、洗濯、すすぎ、脱水、乾燥の各工程を行うドラム式洗濯乾燥機に関するものである。   The present invention relates to a drum-type washing / drying machine in which laundry is accommodated in a rotating drum that is rotatably disposed in a water tub, and each step of washing, rinsing, dehydration, and drying is performed.

水槽内に回転自在に配した回転ドラム内に洗濯物を投入して回転ドラムを回転駆動することにより、洗濯工程、すすぎ工程、脱水工程を順次実行して洗濯物を洗浄するドラム式洗濯機が構成され、このドラム式洗濯機に乾燥機能を設けることにより、脱水工程を終えた洗濯物を乾燥する乾燥工程を実行する機能を備えたドラム式洗濯乾燥機に構成することができる。   A drum-type washing machine for washing laundry by sequentially executing a washing process, a rinsing process, and a dewatering process by putting the laundry in a rotating drum rotatably arranged in the water tank and rotationally driving the rotating drum. Thus, by providing a drying function to the drum type washing machine, a drum type washing and drying machine having a function of executing a drying process of drying the laundry after the dehydration process can be configured.

乾燥機能は、水槽内の湿気を含んだ空気を槽外に排気し、除湿手段により排気した空気中の湿気を除湿した後、加熱手段によって加熱乾燥させた温風にして再び水槽内に送風するように構成することができる。このようなドラム式洗濯乾燥機においては、乾燥工程において洗濯物から発生する糸屑などが回転ドラムに隣接する排気ホースや除湿手段に付着する問題があった。この糸屑等の付着を防止するために、すすぎ工程の水によって付着した糸屑などを洗い流し、循環空気の流れを阻害しないようにしたドラム式洗濯乾燥機が知られている（特許文献１参照）。   In the drying function, air containing moisture in the water tank is exhausted to the outside of the tank, the moisture in the air exhausted by the dehumidifying means is dehumidified, and then heated and dried by the heating means to be blown into the water tank again. It can be constituted as follows. In such a drum-type washing / drying machine, there is a problem that yarn waste generated from the laundry in the drying process adheres to the exhaust hose and the dehumidifying means adjacent to the rotating drum. In order to prevent the attachment of the yarn waste and the like, there is known a drum type washing and drying machine in which the yarn waste attached by the water in the rinsing process is washed away so as not to obstruct the flow of the circulating air (see Patent Document 1). ).

上記ドラム式洗濯乾燥機は、回転ドラムをその回転軸方向が水平方向になるように水槽内に配設しており、乾燥工程を実行するための空気循環経路は、水槽の下方に開口する排気口から水槽内の空気を排気し、送風ファン及びヒータを備えた管路から回転ドラムの正面側開口部から水槽内に送風するように構成されている。従って、排気口につながる排気ホース等に堆積した糸屑等を除去する動作を行うときには、すすぎ工程における給水量を多くすると水槽の下方に開口する排気口は水没し、排気ホースにも水が侵入するので、すすぎ工程における回転ドラムの回転により発生した水流により排気口や排気ホースに付着した糸屑等が洗い流される。更に、この動作に合わせて送風ファンを駆動させると、風圧による水位変動が生じて水の飛散が大きくなり、排水ホースが連結された除湿手段に水の飛散が及んで付着した糸屑等が洗い流される。
特開平１１−３３３１８５号公報（第３〜５頁、図１） In the drum type washing and drying machine, the rotating drum is disposed in the water tank so that the rotation axis direction thereof is horizontal, and the air circulation path for performing the drying process is an exhaust opening below the water tank. The air in the water tank is exhausted from the mouth, and air is blown into the water tank from the opening on the front side of the rotating drum from a pipe line provided with a blower fan and a heater. Therefore, when removing the lint etc. accumulated on the exhaust hose connected to the exhaust port, if the amount of water supply in the rinsing process is increased, the exhaust port opened below the water tank will be submerged and water will also enter the exhaust hose. As a result, yarn waste adhering to the exhaust port and the exhaust hose is washed away by the water flow generated by the rotation of the rotary drum in the rinsing step. Furthermore, when the blower fan is driven in accordance with this operation, the water level fluctuates due to the wind pressure and the scattering of water increases, so that the lint that adheres to the dehumidifying means connected to the drainage hose is washed away. It is.
Japanese Patent Laid-Open No. 11-333185 (pages 3 to 5, FIG. 1)

ドラム式洗濯乾燥機における乾燥機能の向上を図るために、回転ドラム内に収容した洗濯物から湿気を含む空気を排気し、乾燥した温風を洗濯物に満遍なく供給するためには、水槽内からの排気は水槽の上方とし、水槽内への送風は水槽の下方とするのが好ましい構成となる。このような乾燥機能の構成では、排気口は水槽の上方に開口し、それに連通する管路内に除湿手段を設けることになり、従来技術に開示されたようなすすぎ工程における給水制御や送風制御によって除湿手段に付着した糸屑等を洗い流す構成は適用できない。   In order to improve the drying function of the drum type laundry dryer, in order to exhaust air containing moisture from the laundry stored in the rotating drum and supply the dry warm air uniformly to the laundry, the inside of the aquarium It is preferable that the exhaust air is above the water tank and the air blown into the water tank is below the water tank. In the configuration of such a drying function, the exhaust port opens above the water tank, and the dehumidifying means is provided in the pipe line communicating with the water tank, so that the water supply control and the air blow control in the rinsing process as disclosed in the prior art are performed. Therefore, it is not possible to apply a configuration in which the lint attached to the dehumidifying means is washed away.

本発明が目的とするところは、より好ましい乾燥機能を構成する場合に、除湿手段に付着する糸屑等を効果的に除去する構成を設けたドラム式洗濯乾燥機を提供することにある。   An object of the present invention is to provide a drum-type washing and drying machine provided with a configuration for effectively removing lint and the like adhering to the dehumidifying means when a more preferable drying function is configured.

上記目的を達成するために本発明に係るドラム式洗濯乾燥機は、周壁に多数の透孔が形成され洗濯物を収容する円筒形の回転ドラムと、前記回転ドラムをその回転軸方向が正面側から背面側に向けて下向き傾斜になるように内部に回転自在に支持する水槽と、前記回転ドラムを回転駆動するモータと、前記水槽内に給水する給水部と、前記水槽内から排気した空気を除湿手段、糸屑回収フィルタ、送風手段および加熱手段を介して再び前記水槽内に送風する乾燥用空気循環経路と、洗濯、すすぎ、脱水、乾燥の各工程に応じて各部の動作を制御する制御手段とを備え、前記水槽には、前記除湿手段を収容した除湿手段収容室を前記水槽の側周面上方部位に前記水槽と一体に形成すると共に、前記水槽の側周壁に、前記除湿手段収容室に通じる排気口が前記回転ドラムの所定の回転方向の略接線方向に開口するように形成され、前記制御手段は、少なくとも前記すすぎ工程において、前記水槽内に所定量の水を溜めた状態で前記回転ドラムを所定回転数で回転させるように制御することで、前記水槽内に溜められた水が前記回転ドラムの回転により前記水槽の側周面に添って回転し、前記排気口から前記除湿手段収容室に流入するようにしたことを特徴とする。 Drum type washing and drying machine according to the present invention in order to achieve the above object, a rotary drum of cylindrical serve a large number of through holes are formed wash濯物in the peripheral wall, the rotary drum is the axial direction A water tank that is rotatably supported inside so as to be inclined downward from the front side toward the back side, a motor that rotationally drives the rotating drum, a water supply unit that supplies water into the water tank, and exhausted from the water tank a drying air circulation passage for blowing dehumidifier air, lint collection filter, again with via blowing means and the heating hands stage the water tank, the washing, rinsing, dehydration, the operation of each part according to the steps of drying and control means for controlling, wherein the water tank, the dehumidifying means accommodating chamber which accommodates said dehumidifier and forming on the water tank integrally to the side peripheral surface upper portion of the tub, the side wall of the water tub, leading to the dehumidification means accommodating chamber Gas port is formed to open in a substantially tangential direction of the predetermined rotation direction of the rotary drum, wherein, at least the rinsing step, the rotating drum in a state in which reservoir a predetermined amount of water to the water tank The water stored in the water tank is rotated along the side surface of the water tank by the rotation of the rotating drum, and the dehumidifying means accommodating chamber is rotated from the exhaust port. It is made to flow in .

上記構成によれば、水槽の側周面上方に除湿手段収容室に通じる排気口が回転ドラム回転方向の略接線方向に開口しているので、水が給水された水槽内で回転ドラムが回転すると、跳ね上げられた水は主に回転方向の接線方向に飛散して排気口から勢いよく除湿手段収容室内に流入する。乾燥工程において洗濯物から発生した糸屑等は排気空気に混入して排気口から除湿手段収容室に入るので、除湿手段や室壁に糸屑等が付着しやすくなり、それが堆積すると除湿機能や送風機能を損なうことになるが、排気口から水が流入する構造が形成されていることにより、勢いよく流入する水によって付着した糸屑等は洗い流される。また、水槽に隣接して設けることができ、排気口から除湿手段収容室までの距離が短くなり、水槽から排気口を通って除湿手段収容室に水が流入しやすく、勢いよく水が流入するので、糸屑等を洗い流す効果も大きくなる。さらに、少なくともすすぎ工程における水を除湿手段収容室に流入させることにより汚れのない水で除湿手段等を洗うことができる。 According to the above configuration, since the exhaust port leading to the dehumidifying means accommodation chamber opens above the side peripheral surface of the water tank in a substantially tangential direction of the rotation drum rotation direction, when the rotation drum rotates in the water tank supplied with water. The splashed water mainly scatters in the tangential direction of the rotation direction, and vigorously flows into the dehumidifying means accommodation chamber from the exhaust port. Waste yarn generated from the laundry in the drying process is mixed into the exhaust air and enters the dehumidifying means storage chamber from the exhaust port, so that it becomes easy for the lint etc. to adhere to the dehumidifying means and the chamber wall, and if it accumulates, the dehumidifying function Although it will impair the air blowing function, the yarn waste adhering to the water flowing in vigorously is washed away because of the structure in which water flows in from the exhaust port. Moreover , it can be provided adjacent to the water tank, the distance from the exhaust port to the dehumidifying means accommodation chamber is shortened, water easily flows from the water tank through the exhaust port to the dehumidifying means accommodation chamber, and the water flows in vigorously. Therefore, the effect of washing away lint is also increased. Furthermore, the dehumidifying means and the like can be washed with clean water by flowing water at least in the rinsing step into the dehumidifying means accommodation chamber.

本発明によれば、乾燥工程において洗濯物から発生する糸屑等が除湿手段収容室内に付着しても、すすぎ工程において水槽内に貯留された水が回転ドラムの回転によって跳ね上げられて排気口から除湿手段収容室内に勢いよく流入して付着した糸屑等を洗い流すことができ、糸屑等の付着堆積による乾燥機能の低下を防止することができる。   According to the present invention, even if lint or the like generated from the laundry in the drying process adheres to the dehumidifying means accommodation chamber, the water stored in the water tank in the rinsing process is splashed up by the rotation of the rotating drum, and the exhaust port. Accordingly, the yarn waste that has flowed into the dehumidifying means housing chamber vigorously and adhered thereto can be washed away, and the drying function can be prevented from being lowered due to the adhesion and accumulation of yarn waste and the like.

図１は、実施形態に係るドラム式洗濯乾燥機１の要部構成を示すもので、洗濯機筐体６内には図示しないサスペンション構造によって水槽３が斜め傾斜した状態に支持され、水槽３内には有底円筒形に形成された回転ドラム２が回転自在に支持されている。回転ドラム２は水槽３の背面に取り付けられたドラム駆動モータ７によって回転速度可変及び回転方向切換可能に回転駆動される。また、回転ドラム２は、その回転軸方向が図示するように開口する正面側から底面となる背面側に向けて下向き傾斜となるように傾斜配置されているため、洗濯機筐体６の正面側に形成された傾斜面６ａに開閉自在に設けられた扉体９を開くと、回転ドラム２に対する洗濯物の出し入れする作業に際して腰を屈める具合が少なくてすみ、また、ドラム式洗濯乾燥機１の正面側に余裕のある空間を確保する必要もないので、洗面所などの狭い空間にも設置可能なドラム式洗濯乾燥機１に構成することができる。   FIG. 1 shows a configuration of a main part of a drum-type washing / drying machine 1 according to the embodiment. A water tank 3 is supported in an obliquely inclined state by a suspension structure (not shown) in a washing machine housing 6, The rotary drum 2 formed in a bottomed cylindrical shape is rotatably supported. The rotary drum 2 is rotationally driven by a drum drive motor 7 attached to the back of the water tank 3 so that the rotational speed can be varied and the rotational direction can be switched. Further, since the rotating drum 2 is inclined so that the direction of the rotation axis is inclined downward from the front side opening as shown in the drawing toward the back side as the bottom surface, the front side of the washing machine casing 6 is arranged. Opening the door body 9 that can be freely opened and closed on the inclined surface 6a formed on the rotating drum 2 reduces the amount of bending when the laundry is taken in and out of the rotary drum 2, and the drum type laundry dryer 1 Since there is no need to secure a space on the front side, the drum type washing / drying machine 1 can be installed in a narrow space such as a washroom.

前記洗濯機筐体６内には、上記構成要素の他に、水槽３内に水を給水するための給水部１２や、水槽３内の水を外部に排水するための排水部１３などが配設され、更に、図２に示すように、回転ドラム２内に収容した洗濯物を乾燥する乾燥工程が実施できるように、排気口２１から排気した水槽３内の空気を除湿手段収容室１６、糸屑回収フィルタ１７、送風管路１８を通して送風口２２から再び水槽３内に送風する乾燥用空気循環経路が構成されている。   In addition to the above-described components, the washing machine housing 6 includes a water supply unit 12 for supplying water into the aquarium 3, a drainage unit 13 for draining water in the aquarium 3 to the outside, and the like. Further, as shown in FIG. 2, the air in the water tank 3 exhausted from the exhaust port 21 is removed from the dehumidifying means accommodating chamber 16, so that the drying process of drying the laundry accommodated in the rotary drum 2 can be performed. An air circulation path for drying that blows air again from the air blowing port 22 into the water tank 3 through the yarn waste collecting filter 17 and the air blowing pipe 18 is configured.

上記構成になるドラム式洗濯乾燥機１は、図示しない制御装置による制御動作により洗濯工程、すすぎ工程、脱水工程を実行すると共に、必要に応じて乾燥工程が実行される。   The drum-type washing / drying machine 1 configured as described above executes a washing process, a rinsing process, and a dehydrating process by a control operation by a control device (not shown), and a drying process is executed as necessary.

扉体９を開いて回転ドラム２内に洗濯物を投入し、給水部１２に設けられた洗剤投入口に所要量の洗剤を投入して洗濯機筐体６の表面上に設けられた操作パネルから運転開始の操作を行うと、給水部１２から水槽３内に洗濯物のように対応する所定量の給水がなされ、回転ドラム２がドラム駆動モータ７によって回転駆動されることにより、洗濯工程が実施される。洗濯工程が終了すると、排水部１３から汚れた洗濯水が外部に排出され、回転ドラム２を高速回転させて洗濯物から洗濯水が脱水され、給水部１２から新たに水槽３内に水が給水されてすすぎ工程が実施される。すすぎ工程が終了すると、回転ドラム２を高速回転させて洗濯物に含まれるすすぎ水を脱水する脱水工程が実施される。脱水工程に引き続いて乾燥工程を実施する運転コースが選択されている場合には、水槽３内の空気を排気して湿気を含む空気から除湿し、加熱して乾燥した温風として再び水槽３内に送風する乾燥工程が実施される。   An operation panel provided on the surface of the washing machine housing 6 by opening the door body 9 and putting laundry into the rotating drum 2 and putting a required amount of detergent into the detergent inlet provided in the water supply section 12. When the operation for starting the operation is performed, a predetermined amount of water is supplied from the water supply unit 12 into the water tub 3 like a laundry, and the rotary drum 2 is rotationally driven by the drum drive motor 7, so that the washing process is performed. To be implemented. When the washing process is completed, the dirty washing water is discharged from the drainage unit 13, the rotating drum 2 is rotated at a high speed, the washing water is dehydrated from the laundry, and water is newly supplied from the water supply unit 12 into the water tank 3. Then, the rinsing process is performed. When the rinsing process is completed, a dehydrating process is performed in which the rotating drum 2 is rotated at a high speed to dehydrate the rinse water contained in the laundry. When the operation course for performing the drying process subsequent to the dehydration process is selected, the air in the water tank 3 is exhausted, dehumidified from the air containing moisture, and heated and dried as warm air in the water tank 3 again. A drying step of blowing air is performed.

図２に示すように、送風ファン１５の回転により回転ドラム２内の空気は周面に形成された透孔８から水槽３内に出て排気口２１から除湿管路（除湿手段収容室）１６内に排気される。除湿管路１６内には除湿手段３８を構成する熱交換器５１と注水ノズル５２とが配設され、注水弁５３が開かれることにより注水された水が注水ノズル５２から前記熱交換器５１上に散水されるので、除湿管路１６内に排気された湿気を含む空気は冷却されて除湿される。除湿管路１６で除湿された空気は糸屑回収フィルタ１７を通過して送風管路１８を通って水槽３の後方に導かれ、水槽３の背面に設けられた加熱管路１９に流れ、ヒータ２０によって加熱されて送風口２２から水槽３内に送風される。水槽３内に送風された空気は回転ドラム２の底面に形成された通気孔３９や透孔８から回転ドラム２内に流入するので、除湿加熱された空気により洗濯物から湿気が奪い取られ、回転ドラム２の回転による攪拌により全ての洗濯物の乾燥が促進され、この空気循環が所定時間繰り返されることにより洗濯物の乾燥がなされる。   As shown in FIG. 2, the air in the rotary drum 2 flows into the water tank 3 through the through holes 8 formed on the peripheral surface by the rotation of the blower fan 15, and the dehumidification conduit (dehumidification means accommodation chamber) 16 from the exhaust port 21. Exhausted inside. A heat exchanger 51 and a water injection nozzle 52 constituting the dehumidifying means 38 are disposed in the dehumidification pipe line 16, and water injected by opening the water injection valve 53 is supplied from the water injection nozzle 52 onto the heat exchanger 51. Therefore, the air containing moisture exhausted into the dehumidifying conduit 16 is cooled and dehumidified. The air dehumidified in the dehumidifying pipe 16 passes through the lint collecting filter 17, passes through the blower pipe 18, is led to the rear of the water tank 3, flows into the heating pipe 19 provided on the back surface of the water tank 3, and is heated. It is heated by 20 and blown into the water tank 3 from the blower port 22. Since the air blown into the water tank 3 flows into the rotary drum 2 through the air holes 39 and the through holes 8 formed on the bottom surface of the rotary drum 2, moisture is taken away from the laundry by the dehumidified and heated air. Drying of all the laundry is promoted by stirring by the rotation of the drum 2, and the laundry is dried by repeating this air circulation for a predetermined time.

図３に示すように、除湿管路１６及び送風管路１８は、樹脂成形によって形成される水槽３と一体化させて同時成形される。除湿管路１６は水槽３の側周面に隣接して形成され、円筒形に形成される水槽３の側周壁の一部を開口させて除湿管路１６に向けて開口する排気口２１が形成されている。排気口２１は回転ドラム２の回転方向の略接線方向に開口している。   As shown in FIG. 3, the dehumidifying duct 16 and the blower duct 18 are formed integrally with the water tank 3 formed by resin molding. The dehumidification pipe line 16 is formed adjacent to the side peripheral surface of the water tank 3, and an exhaust port 21 that opens toward the dehumidification pipe line 16 is formed by opening a part of the side wall of the water tank 3 formed in a cylindrical shape. Has been. The exhaust port 21 opens in a substantially tangential direction of the rotation direction of the rotary drum 2.

乾燥工程が実施されると、洗濯物の乾燥が進行すると共に洗濯物から糸屑等が発生しやすく、送風によって排気口２１から除湿管路１６に流れ込む（矢印Ａ）。空気中に存在する糸屑等は送風管路１８の入口に設けられた糸屑回収フィルタ１７によって空気だけが濾過されて送風管路１８及び加熱管路１９に糸屑等が流れ込まないように構成されているが、それ以前に熱交換器５１や除湿管路１６の内壁に付着する場合が少なくない。糸屑等の付着が増加すると、除湿機能や送風機能を低下させるので、除湿管路１６内に付着した糸屑等を除去する必要がある。   When the drying process is carried out, the laundry is dried and yarns and the like are easily generated from the laundry, and flows into the dehumidifying conduit 16 from the exhaust port 21 by the air blowing (arrow A). The lint and the like existing in the air are configured so that only the air is filtered by the lint collecting filter 17 provided at the inlet of the blower duct 18 and the lint and the like do not flow into the blower duct 18 and the heating duct 19. However, there are many cases where it adheres to the inner wall of the heat exchanger 51 or the dehumidifying duct 16 before that. If the attachment of yarn waste or the like increases, the dehumidifying function or the air blowing function is lowered, and therefore it is necessary to remove the yarn waste or the like attached in the dehumidifying conduit 16.

本実施形態においては、除湿管路１６内に付着した糸屑等を除去するために、すすぎ工程時に回転ドラム２を所定回転数で回転させることによって、その回転方向（矢印Ｂ）に跳ね上げられる水を排気口２１から除湿管路１６内に勢いよく流入させ（矢印Ｃ）、熱交換器５１や管路壁に付着した糸屑等を洗い流すことができる。なお、この場合の回転ドラム２の所定回転数は、回転ドラム２の回転の遠心力により、水が跳ね上がり、その水が水槽３の内壁に添って回転する回転数であればよい（たとえば、回転ドラム２の直径が５００±５０ｍｍ程度であるとき、１５０ｒ／ｍｉｎ程度）。 In the present embodiment, in order to remove the yarn waste or the like adhering to the dividing Shimekanro 16, by rotating the rotary drum 2 at a predetermined rotational speed during the rinsing process, is splashed to the rotational direction (arrow B) Water can be vigorously flowed into the dehumidifying pipeline 16 from the exhaust port 21 (arrow C), and the lint and the like adhering to the heat exchanger 51 and the pipeline wall can be washed away. In this case, the predetermined rotational speed of the rotary drum 2 may be any rotational speed at which water jumps up by the centrifugal force of rotation of the rotary drum 2 and rotates along the inner wall of the water tank 3 (for example, rotation When the diameter of the drum 2 is about 500 ± 50 mm, about 150 r / min).

排気口２１は前述したように回転ドラム２の回転方向の略接線方向に開口しているので、すすぎ工程において水槽３の下方に貯留された水が回転ドラム２によって跳ね上げられた水は、主に回転ドラム２の回転方向の接線方向に飛び散り、排気口２１から除湿管路１６内に勢いよく流入する。これがすすぎ工程中に繰り返されることにより、付着した糸屑等は洗い流される。除湿管路１６内には、除湿して生成される水や、注水ノズル５２から注水される水を水槽３内に流し、排水部１３から外部に排出する排水経路が形成されているので、洗い出された糸屑等も排水と共に外部に排出される。   As described above, since the exhaust port 21 is opened in a substantially tangential direction of the rotation direction of the rotary drum 2, water stored below the water tank 3 in the rinsing process is splashed by the rotary drum 2. Then, it scatters in the tangential direction of the rotating direction of the rotating drum 2 and flows into the dehumidifying conduit 16 from the exhaust port 21 vigorously. By repeating this during the rinsing step, the attached lint etc. are washed away. In the dehumidifying conduit 16, there is formed a drainage path that allows water generated by dehumidification and water injected from the water injection nozzle 52 to flow into the water tank 3 and to be discharged from the drainage unit 13 to the outside. The discharged lint and the like are also discharged to the outside along with the drainage.

以上説明した実施形態では回転ドラム２を傾斜配置した構成を示したが、回転ドラム２を水平方向に配置した場合においても同様に構成することができる。   In the embodiment described above, the configuration in which the rotary drum 2 is inclined is shown. However, the same configuration can be made when the rotary drum 2 is arranged in the horizontal direction.

以上の説明の通り本発明により、乾燥工程において洗濯物から発生する糸屑等が除湿手段や壁面に付着しても、洗濯工程又はすすぎ工程において水槽内に貯留された水が回転ドラムの回転によって跳ね上げられる水によって洗い流されるので、付着堆積する糸屑等によって除湿機能や送風機能が低下しないドラム式洗濯乾燥機を提供することができる。   As described above, according to the present invention, even if lint generated from the laundry in the drying process adheres to the dehumidifying means or the wall surface, the water stored in the water tank in the washing process or the rinsing process is caused by the rotation of the rotating drum. Since it is washed away by the splashed water, it is possible to provide a drum-type washing and drying machine in which the dehumidifying function and the air blowing function are not deteriorated by the lint and the like deposited and accumulated.
