Abstract

<P>PROBLEM TO BE SOLVED: To provide a drum type washing machine which prevents laundry from accumulating disproportionately in a lower part on the back side of a rotary drum when the rotary drum is slantingly disposed to take in and out the laundry easily. <P>SOLUTION: The drum type washing machine is equipped with the rotary drum 2 which is formed into a cylindrical shape and has the center of a rotation axis slanted upward from the back surface side to the front side, a water tank 3 including the rotary drum 2 inside, and a baffle 4 protruding on the inner peripheral surface of the rotary drum 2. The top part 4c of the baffle 4 is formed to decrease the height from the back surface side to the front side of the rotary drum 2 to the inner peripheral surface of the rotary drum 2. When the rotary drum 2 is rotated, the action to hold up the laundry diagonally to the front in the rotary drum 2 works on the laundry by forming the side surfaces 4a, 4b of the baffle 4 into a flat shape with a prescribed angle to the radial direction of the rotary drum 2. Consequently, uneven washing is eliminated, and the washing performance is improved since the laundry switches the position in the front and the back. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、回転ドラムをその回転軸心が背面側から正面側に向けて上向き傾斜になるように水槽内に配設したドラム式洗濯機に関するものである。   The present invention relates to a drum-type washing machine in which a rotary drum is disposed in a water tub so that its rotational axis is inclined upward from the back side to the front side.

回転ドラムをその回転軸方向が水平方向になるようにして水槽内に配置したドラム式洗濯機では、円筒形に形成された回転ドラムを回転させることにより、回転ドラム内に収容された洗濯物を回転ドラムの内周面に設けられた突出部であるバッフルに引っ掛けて持ち上げ、持ち上げられた洗濯物が適当な高さから落下することによって洗濯物が叩き洗いされる(例えば、特許文献1参照)。
特開平9−215894号公報
In a drum-type washing machine in which a rotating drum is disposed in a water tub so that the rotation axis direction thereof is horizontal, the laundry stored in the rotating drum is rotated by rotating the rotating drum formed in a cylindrical shape. The laundry is hit by a baffle, which is a protrusion provided on the inner peripheral surface of the rotating drum, and then lifted, and the laundry is beaten and washed by dropping from an appropriate height (for example, see Patent Document 1). .
JP-A-9-215894

前述のようにドラム式洗濯機は洗濯物を主に叩き洗いによって洗濯するので、従来からの主流である回転ドラムを縦方向に配した洗濯機に比して洗濯物を傷め難い構造ではあるが、回転ドラムを横向きに配しているため洗濯物の出し入れは正面側から行うことになり、腰を屈める作業が伴う苦痛や日本の狭い住宅事情に不適な構造とされてきた。このドラム式洗濯機の課題を解決すべく、回転ドラムの開口する側が上向きとなるように回転軸心を傾斜させることにより、洗濯物の出し入れを容易にして、狭い空間にも配置することができるドラム式洗濯機に構成することができる。   As described above, since the drum type washing machine mainly washes laundry by tapping, it has a structure that is less likely to damage the laundry than a washing machine in which a rotating drum, which is the mainstream from the past, is arranged in the vertical direction. Since the rotating drum is placed sideways, the laundry is put in and out from the front side, and it has become an unsuitable structure for the pain associated with bending the waist and the narrow housing situation in Japan. In order to solve the problem of the drum type washing machine, the rotation axis is inclined so that the opening side of the rotating drum faces upward, so that the laundry can be easily put in and out and can be arranged in a narrow space. It can be configured as a drum-type washing machine.

しかし、回転ドラムを水平方向から傾斜させると、洗濯時に回転ドラム内に収容された洗濯物は回転ドラムの背面側に偏ってしまうため、従来構造のバッフルでは、洗濯物を適正に持ち上げて落下させる叩き洗いの作用が満足になされず、また撹拌が不十分であるため、洗濯物の濡れ速度が遅いなどの課題があった。また、乾燥時には回転ドラム内に収容された洗濯物は回転ドラムの背面側に偏って圧迫されて撹拌されるため、従来構造のバッフルでは、洗濯物の乾燥後の仕上りが悪くなるという課題があった。   However, if the rotating drum is tilted from the horizontal direction, the laundry housed in the rotating drum at the time of washing is biased toward the back side of the rotating drum. Therefore, in the baffle of the conventional structure, the laundry is properly lifted and dropped. There was a problem in that the action of tapping was not satisfactory and stirring was insufficient, so that the rate of wetting of the laundry was slow. In addition, since the laundry housed in the rotating drum is biased toward the back side of the rotating drum and stirred when drying, the baffle having the conventional structure has a problem that the finished finish of the laundry becomes worse. It was.

本発明が目的とするところは、回転ドラムを傾斜させて配置した構造においても洗濯時には洗濯物の撹拌が充分になされ、乾燥時にも洗濯物が圧迫されず、広がって撹拌され、乾燥後の仕上りを向上させるバッフル構造を備えたドラム式洗濯機を提供することにある。   The object of the present invention is that even in a structure in which the rotating drum is inclined, the laundry is sufficiently agitated during washing, the laundry is not compressed even during drying, spread and agitated, and the finished finish after drying. Another object of the present invention is to provide a drum-type washing machine having a baffle structure that improves the efficiency.

前記従来の課題を解決するために、本発明のドラム式洗濯機は、円筒形に形成されその回転軸心が背面側から正面側に向けて上向き傾斜となる回転ドラムと、前記回転ドラムを内包する水槽と、前記回転ドラムの内周面に突出して設けたバッフルとを備え、前記バッフルの頂上部は、前記回転ドラムの内周面に対し前記回転ドラムの背面側から正面側に向けて高さが低くなるように形成され、前記バッフルの側面は、前記回転ドラムの径方向に対し所定の角度を有する平面状としたことを特徴とする。   In order to solve the above-described conventional problems, a drum-type washing machine of the present invention includes a rotary drum that is formed in a cylindrical shape and whose rotation axis is inclined upward from the back side to the front side, and includes the rotary drum. And a baffle protruding from the inner peripheral surface of the rotating drum, and the top of the baffle is higher than the inner peripheral surface of the rotating drum from the back side to the front side of the rotating drum. The side surface of the baffle is formed in a planar shape having a predetermined angle with respect to the radial direction of the rotating drum.

これによって、回転ドラムを回転させると、洗濯時に洗濯物には回転ドラム内で斜め前方向に持ち上げられる作用が及ぶため、傾斜配置された回転ドラム内の低い背面側の位置に偏ってしまうことがなく、洗濯物の前後位置の入れ替わりがよくなり、洗濯液が少ない状態でも洗濯物の全てが満遍なく洗濯液に浸されるため、洗いむらが少なく、洗浄性能を向上させることができる。   Accordingly, when the rotating drum is rotated, the laundry is lifted obliquely forward in the rotating drum at the time of washing, so that it may be biased to a lower back side position in the inclined rotating drum. In addition, the front / rear position of the laundry is improved, and even when the amount of the washing liquid is small, all the laundry is evenly immersed in the washing liquid, so that there is little unevenness in washing and the washing performance can be improved.

本発明によれば、回転ドラムを傾斜配置して洗濯物の出し入れを容易にしたドラム式洗濯機において、洗濯時に洗濯物が回転ドラム内の背面側に偏ってしまい洗浄性能が悪くなってしまうといった課題は、バッフルの頂上部を、回転ドラムの内周面に対し回転ドラムの背面側から正面側に向けて高さが低くなるように形成し、バッフルの側面は、回転ドラムの径方向に対し所定の角度を有する平面状とした構成によりによって解決され、洗いむらが少なく、洗浄性能を向上させたドラム式洗濯機を提供できる。   According to the present invention, in a drum-type washing machine in which a rotating drum is arranged at an inclination to facilitate taking in and out of laundry, the laundry is biased toward the back side in the rotating drum at the time of washing, and the cleaning performance is deteriorated. The problem is that the top of the baffle is formed so that its height decreases from the inner surface of the rotating drum toward the front side of the rotating drum, and the side surface of the baffle is in the radial direction of the rotating drum. A drum-type washing machine that is solved by the flat configuration having a predetermined angle, has less unevenness in washing, and has improved washing performance can be provided.

第1の発明のドラム式洗濯機は、円筒形に形成されその回転軸心が背面側から正面側に向けて上向き傾斜となる回転ドラムと、前記回転ドラムを内包する水槽と、前記回転ドラムの内周面に突出して設けたバッフルとを備え、前記バッフルの頂上部は、前記回転ドラムの内周面に対し前記回転ドラムの背面側から正面側に向けて高さが低くなるように形成され、前記バッフルの側面は、前記回転ドラムの径方向に対し所定の角度を有する平面状とすることにより、回転ドラムを回転させると、洗濯時に洗濯物には回転ドラム内で斜め前方向に持ち上げられる作用が及ぶため、傾斜配置された回転ドラム内の低い背面側の位置に偏ってしまうことがなく、洗濯物の前後位置の入れ替わりがよくなり、洗濯液が少ない状態でも洗濯物の全てが満遍なく洗濯液に浸されるため、洗いむらが少なく、洗浄性能を向上させることができる。   A drum-type washing machine according to a first aspect of the present invention is a cylindrical drum, the rotation axis of which is inclined upward from the back side to the front side, a water tub containing the rotation drum, and the rotation drum. A baffle that protrudes from the inner peripheral surface, and the top of the baffle is formed such that the height of the baffle decreases from the inner peripheral surface of the rotating drum toward the front side from the back side of the rotating drum. The side surface of the baffle is a flat surface having a predetermined angle with respect to the radial direction of the rotating drum. When the rotating drum is rotated, the laundry is lifted obliquely forward in the rotating drum during washing. Because it works, it will not be biased to the low back side position in the inclined rotating drum, the front and rear position of the laundry will be changed better, and all the laundry will be universal even when there is little washing liquid Since immersed in Ku washing liquid, it is possible to improve little washing uneven, the cleaning performance.

第2の発明のドラム式洗濯機は、特に、第1の発明のドラム式洗濯機のバッフルの頂上部は、前記バッフルが回転ドラムの最下部に位置した状態で、水平面に対し前記回転ドラムの正面側から背面側にむけて高さが低くなるように形成されたことにより、回転ドラム内の容積を確保することができるので、洗濯物の移動を最適にすることができる。   In the drum type washing machine of the second invention, in particular, the top of the baffle of the drum type washing machine of the first invention has the baffle positioned at the lowermost part of the rotating drum, and the rotating drum Since the volume in the rotating drum can be secured by forming the height from the front side to the back side, the laundry can be moved optimally.

第3の発明のドラム式洗濯機は、特に、第1または第2の発明のドラム式洗濯機のバッフルの後端部は、回転ドラムの背面に接することにより、回転ドラムの背面側にある洗濯物がバッフル後縁に引っ掛かって、正面側に移動するのを阻害することがなく、洗濯物の位置の入れ替わりがよくなり、洗浄力を向上させることができる。   The drum type washing machine according to the third aspect of the invention is, in particular, the rear end of the baffle of the drum type washing machine according to the first or second aspect of the invention being in contact with the back side of the rotary drum, so that the washing on the back side of the rotary drum is performed. There is no hindrance to the object being caught on the rear edge of the baffle and moving to the front side, the change of the position of the laundry is improved, and the cleaning power can be improved.

第4の発明のドラム式洗濯機は、特に、第1〜3のいずれか1つの発明のドラム式洗濯機のバッフルの頂上部に、背面側から正面側にわたって略直方体状の撹拌突起を形成したことにより、少量の洗濯物を撹拌する際においても、撹拌突起が確実に洗濯物を引っ掛けることで、洗濯物が浮き上がって空回りすることを防止でき、洗濯物が少量のときでも確実な洗浄力を確保することができ、このように撹拌突起を形成することで、洗濯物に回転ドラム内で斜め前方向に持ち上げられる作用と、少量の洗濯物を確実に撹拌する作用とを両立させることができる。   In the drum type washing machine of the fourth invention, in particular, a substantially rectangular parallelepiped stirring protrusion is formed from the back side to the front side at the top of the baffle of the drum type washing machine of any one of the first to third inventions. Therefore, even when a small amount of laundry is being stirred, the agitation protrusions can reliably catch the laundry so that the laundry can be prevented from floating and spinning around. By forming the stirring protrusion in this way, it is possible to achieve both the action of lifting the laundry diagonally forward in the rotating drum and the action of reliably stirring a small amount of laundry. .

第5の発明のドラム式洗濯機は、特に、第4の発明のドラム式洗濯機のバッフルは、その内部を中空状にし、撹拌突起の天面に内部と導通した複数の導通孔を形成したことにより、洗濯時にバッフルがドラムの下方にあるときに、洗濯液を中空の内部に溜め、バッフルが回転しながら上方に移動する際に洗濯液は撹拌突起内に集まり、複数の導通孔に洗濯液を集中して突出することができ、これにより、洗濯物の上方より大量の洗濯液を供給することが可能となり、洗濯物の濡れ速度を速め、さらに洗浄力を向上させることができる。   In the drum-type washing machine of the fifth invention, in particular, the baffle of the drum-type washing machine of the fourth invention has a hollow interior, and a plurality of conduction holes are formed on the top surface of the stirring protrusion. Thus, when the baffle is below the drum during washing, the washing liquid is stored in the hollow interior, and when the baffle moves upward while rotating, the washing liquid collects in the stirring protrusion and is washed in the plurality of conduction holes. The liquid can be concentrated and protruded, whereby a large amount of the washing liquid can be supplied from above the laundry, and the wetting speed of the laundry can be increased, and the cleaning power can be further improved.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(実施の形態1)
図1は、本発明の第1の実施形態におけるドラム式洗濯機1の要部縦断面図を示すものである。
(Embodiment 1)
FIG. 1 shows a longitudinal sectional view of an essential part of a drum type washing machine 1 according to a first embodiment of the present invention.

図1において、筐体6内に図示しないサスペンション構造によって水槽3が宙吊り状態に配設され、水槽3内に有底円筒形に形成された回転ドラム2がその軸心方向を背面側から正面側に向けて上向きに傾斜させて配設されている。水槽3の正面側には回転ドラム2の開口端に通じる洗濯物出入口11が形成され、筐体6の正面側に形成された上向き傾斜面に設けられた開口部を開閉可能に閉じる扉9を開くことにより、洗濯物出入口11を通じて回転ドラム2内に対して洗濯物を出し入れすることができる。扉9が上向き傾斜面に設けられているため、洗濯物を出し入れする作業を腰を屈めることなく実施でき、一般には横向きにある開口部から洗濯物を出し入れするドラム式洗濯機の作業性の悪さが改善されている。   In FIG. 1, a water tank 3 is suspended in a housing 6 by a suspension structure (not shown), and a rotating drum 2 formed in a bottomed cylindrical shape in the water tank 3 has its axial center direction from the back side to the front side. It is arranged so as to be inclined upward. A laundry doorway 11 leading to the opening end of the rotary drum 2 is formed on the front side of the water tub 3, and a door 9 that closes an opening provided on an upward inclined surface formed on the front side of the housing 6 so as to be openable and closable. By opening, the laundry can be taken in and out of the rotary drum 2 through the laundry entrance 11. Since the door 9 is provided on the upward inclined surface, the work for putting in and out the laundry can be carried out without bending the waist, and generally the workability of the drum type washing machine for taking in and out the laundry from the sideways opening is provided. The evil has been improved.

回転ドラム2には、その周面に水槽3内に通じる多数の透孔8が形成され、内周面の複数位置にバッフル4が設けられている。この回転ドラム2は水槽3の背面側に取り付けられたモータ7によって正転及び逆転方向に回転駆動される。また、水槽3には、注水管路12及び排水管路13が配管接続され、図示しない注水弁および排水弁の制御によって水槽3内への注水及び排水がなされる。   The rotating drum 2 is formed with a large number of through holes 8 communicating with the water tank 3 on its peripheral surface, and baffles 4 are provided at a plurality of positions on the inner peripheral surface. The rotating drum 2 is rotationally driven in the forward and reverse directions by a motor 7 attached to the back side of the water tank 3. In addition, a water injection pipe 12 and a drain pipe 13 are connected to the water tank 3, and water injection and drainage into the water tank 3 is performed by controlling a water injection valve and a water discharge valve (not shown).

扉9を開いて回転ドラム2内に洗濯物及び洗剤を投入してドラム式洗濯機1の運転を開始させると、水槽3内には注水管路12から所定量の注水がなされ、モータ7により回転ドラム2が回転駆動されて洗濯行程が開始される。回転ドラム2の回転により、回転ドラム2内に収容された洗濯物は回転ドラム2の内周面に設けられたバッフル4によって回転方向に持ち上げられ、持ち上げられた適当な高さ位置から落下する撹拌動作が繰り返されるので、洗濯物には叩き洗いの作用が及んで洗濯がなされる。所要の洗濯時間の後、汚れた洗濯液は排水管路13から排出され、回転ドラム2を高速回転させる脱水動作により洗濯物に含まれた洗濯液を脱水し、その後、水槽3内に注水管路12から注水してすすぎ行程が実施される。このすすぎ行程においても回転ドラム2内に収容された洗濯物は回転ドラム2の回転によりバッフル4により持ち上げられて落下する撹拌動作が繰り返されてすすぎ洗いが実施される。すすぎ行程の後、すすぎ液は排水管路13から排出され、回転ドラム2を高速回転させる脱水動作により洗濯物に含まれたすすぎ液を脱水し、洗濯行程が終了する。   When the door 9 is opened and laundry and detergent are put into the rotating drum 2 to start the operation of the drum-type washing machine 1, a predetermined amount of water is injected into the water tank 3 from the water injection pipe 12. The rotating drum 2 is driven to rotate and the washing process is started. By the rotation of the rotating drum 2, the laundry accommodated in the rotating drum 2 is lifted in the rotating direction by the baffle 4 provided on the inner peripheral surface of the rotating drum 2, and agitated by dropping from the lifted appropriate height position. Since the operation is repeated, the laundry has the effect of tapping and washing. After the required washing time, the dirty washing liquid is discharged from the drain pipe 13, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation that rotates the rotating drum 2 at a high speed. Rinsing is performed by pouring water from the road 12. In this rinsing process, the laundry stored in the rotary drum 2 is rinsed by repeating the stirring operation of being lifted and dropped by the baffle 4 by the rotation of the rotary drum 2. After the rinsing process, the rinsing liquid is discharged from the drain pipe 13, and the rinsing liquid contained in the laundry is dehydrated by the dehydrating operation of rotating the rotary drum 2 at a high speed, and the washing process is completed.

ここで、本第1の実施形態のように回転ドラム2を水平方向から傾斜させて配設した構成では、回転ドラム2の回転により洗濯物を撹拌しようとしても洗濯物が回転ドラム2の背面側に偏って撹拌が充分になされないことになる。即ち、回転ドラム2の回転に伴って洗濯物を回転ドラム2内の背面側から正面側に向けて移動させる撹拌作用がなされるようにする必要がある。このためには、回転ドラム2内に設けられたバッフル4の形状が重要となる。   Here, in the configuration in which the rotary drum 2 is inclined from the horizontal direction as in the first embodiment, the laundry is on the back side of the rotary drum 2 even if the laundry is stirred by the rotation of the rotary drum 2. Therefore, stirring is not sufficiently performed. That is, it is necessary to perform a stirring action of moving the laundry from the back side to the front side in the rotating drum 2 as the rotating drum 2 rotates. For this purpose, the shape of the baffle 4 provided in the rotary drum 2 is important.

図2(a)に本第1の実施形態のドラム式洗濯機におけるバッフル4の平面図、図2(b)に同バッフル4の側面図、図2(c)に同バッフル4の正面図を示す。   2A is a plan view of the baffle 4 in the drum type washing machine of the first embodiment, FIG. 2B is a side view of the baffle 4, and FIG. 2C is a front view of the baffle 4. Show.

バッフル4の頂上部4cは、背面側から正面側に向けてその高さが低くなるよう交際されている。バッフル4の側面4a、4bは、回転ドラム2の径方向(図2(c)の上方向)に対し、左右対称に所定の角度を有し、平面状に形成されている。これにより、左右の側面4a、4bと回転ドラム2が交わる交線間の幅は回転ドラム2背面側から正面側に向けて狭くなる。このとき、バッフル4の前端部4d、後端部4eは略二等辺三角形状となり、その関係は前縁部4dが後縁部4eより小さい相似の関係となる。   The top 4c of the baffle 4 is associated with the height of the baffle 4 so that its height decreases from the back side to the front side. The side surfaces 4a and 4b of the baffle 4 have a predetermined angle symmetrically with respect to the radial direction of the rotating drum 2 (upward direction in FIG. 2C) and are formed in a planar shape. Thereby, the width between the intersecting lines where the left and right side surfaces 4a, 4b and the rotating drum 2 intersect becomes narrower from the back side of the rotating drum 2 toward the front side. At this time, the front end portion 4d and the rear end portion 4e of the baffle 4 have a substantially isosceles triangle shape, and the relationship is similar to the front edge portion 4d smaller than the rear edge portion 4e.

図1に示すように、上記構成になるバッフル4が内周面の複数箇所(例えば、3箇所)に取り付けられた回転ドラム2を、洗濯またはすすぎの行程において、正面からみて右回転させると、傾斜した回転ドラム2内で背面側の低い位置側に偏りがちになる洗濯物は、側面4aに添って背面側から正面側に持ち上げて移動させられるようになるので、回転ドラム2を傾斜配置しても洗濯物は回転ドラム2の背面側の低い側に偏らずに充分に撹拌され、洗濯物の場所の入れ替わりと混ざりがよく、洗濯効果を低下させることがない。   As shown in FIG. 1, when the rotating drum 2 having the baffle 4 configured as described above attached to a plurality of locations (for example, 3 locations) on the inner peripheral surface is rotated clockwise as viewed from the front in a washing or rinsing process, The laundry that tends to be biased toward the lower position on the back side in the inclined rotating drum 2 can be lifted and moved from the back side to the front side along the side surface 4a. However, the laundry is sufficiently agitated without being biased toward the lower side on the back side of the rotary drum 2, and the laundry is easily mixed and mixed, so that the washing effect is not reduced.

また、洗濯物の量が多い場合には、洗濯液の水面に対し洗濯物の大部分が上方に位置するので、洗濯液に浸らない部分も多くなり、全ての洗濯物が満遍なく浸る状態が得られるようにするには、洗濯物の場所の入れ替わりが充分になされるように撹拌する必要がある。上記バッフル4の形状であれば、洗濯物の位置の入れ替えが充分になされるので、洗いむらがなく洗浄力を向上させることができる。   Also, when the amount of laundry is large, most of the laundry is located above the surface of the washing liquid, so there are many parts that are not soaked in the washing liquid, so that all the laundry can be immersed evenly. In order to be able to do so, it is necessary to stir so that the place of the laundry is sufficiently changed. If it is the shape of the said baffle 4, since the replacement | exchange of the position of the laundry is fully made, there is no washing nonuniformity and it can improve cleaning power.

また、図1に示すように、バッフル4の頂上部4cは、バッフル4が回転ドラム2の最下部に位置した状態で、水平面Xに対し回転ドラム2の正面側から背面側にむけて高さが低くなるように形成されている。これにより、バッフル4の容積を大きくすることがないので、回転ドラム内の容積を確保することができ、洗濯物の移動を最適にすることができる。また、水槽3の背面側には、モータ7等の重量物が取り付けられており、水槽3全体の重心は後方よりある。この構造で、脱水時には、洗濯物が回転ドラム2の前方側にあると水槽3の振れ回りが大きくなり、一方、洗濯物を重心より(回転ドラム2の後方側)にあると水槽の振れ回りは小さくなり低振動化を実現できる。すなわち、バッフル4の頂上部4cを、バッフル4が回転ドラム2の最下部に位置した状態で、水平面Xに対し回転ドラム2の正面側から背面側にむけて高さが低くなるように形成することにより、脱水時に、洗濯物が回転ドラム2の前方側に偏り過ぎることはなく、適度に回転ドラム2の前後に散けるので、低振動化を実現できる。   Further, as shown in FIG. 1, the top 4 c of the baffle 4 has a height from the front side to the back side of the rotary drum 2 with respect to the horizontal plane X with the baffle 4 positioned at the lowermost part of the rotary drum 2. Is formed to be low. Thereby, since the volume of the baffle 4 is not increased, the volume in the rotating drum can be secured, and the movement of the laundry can be optimized. Further, a heavy object such as a motor 7 is attached to the back side of the water tank 3, and the center of gravity of the entire water tank 3 is from the rear. With this structure, when the laundry is on the front side of the rotating drum 2, when the laundry is on the front side, the swing of the aquarium 3 increases. On the other hand, if the laundry is on the center of gravity (the rear side of the rotating drum 2) Can be reduced and vibration can be reduced. That is, the top 4c of the baffle 4 is formed so that the height decreases from the front side to the back side of the rotary drum 2 with respect to the horizontal plane X in a state where the baffle 4 is positioned at the lowermost part of the rotary drum 2. Thus, during the dehydration, the laundry is not excessively biased toward the front side of the rotating drum 2 and can be appropriately scattered before and after the rotating drum 2, so that low vibration can be realized.

また、バッフル4の後縁部4eは、回転ドラム2の背面側に接して取り付けることにより、回転ドラムの背面側にある洗濯物がバッフル後縁に引っ掛かって、正面側に移動するのを阻害することがなく、洗濯物の位置の入れ替わりがよくなり、洗浄力を向上させることができる。   Further, the rear edge 4e of the baffle 4 is attached in contact with the back side of the rotary drum 2, thereby preventing the laundry on the back side of the rotary drum from being caught by the rear edge of the baffle and moving to the front side. In this way, the position of the laundry can be changed and the cleaning power can be improved.

このようにバッフル14の左右の側面14a、14bが交わる頂上部に、背面側から正面側にわたって略直方体状の撹拌突起14cを形成したことにより、少量の洗濯物を撹拌する際に、撹拌突起14cが確実に洗濯物を引っ掛けることで、洗濯物が浮き上がって空回りすることがなく、洗濯物が少量のときでも確実な洗浄力を確保することができる。これにより、洗濯物に回転ドラム2内で、斜め前方向に持ち上げられる作用と、少量の洗濯物を確実に撹拌する作用とを両立させることができる。   In this way, when the left and right side surfaces 14a, 14b of the baffle 14 intersect with each other, the stirring protrusion 14c having a substantially rectangular parallelepiped shape is formed from the back side to the front side, so that when stirring a small amount of laundry, the stirring protrusion 14c. However, when the laundry is reliably hooked, the laundry does not float up and runs idle, and a reliable cleaning power can be ensured even when the amount of laundry is small. As a result, it is possible to achieve both the action of the laundry being lifted diagonally forward in the rotary drum 2 and the action of reliably stirring a small amount of laundry.

尚、上記構成において、撹拌突起14cは略直方体状で形成しているが、略直方体状でなくてもよく、側面14a、14bよりも傾斜が急であればよい。   In the above-described configuration, the stirring protrusion 14c is formed in a substantially rectangular parallelepiped shape, but may not be in a substantially rectangular parallelepiped shape, as long as the inclination is steeper than the side surfaces 14a and 14b.

(Embodiment 3)
4A is a plan view of the baffle 24 in the drum-type washing machine of the third embodiment, FIG. 4B is a side view of the baffle 24, and FIG. 4C is a front view of the baffle 24. . Other configurations and operations are the same as those in the first embodiment and the second embodiment, and thus the same reference numerals are given and description thereof is omitted.

図3(a)、(b)、(c)に示すように、バッフル24の左右の側面24a、24bが交わる頂上部に、背面側から正面側にわたって略直方体状の撹拌突起24cを形成している。このバッフル24の内部は、中空状になっており、撹拌突起24cの天面に内部の中空部と導通した複数の導通孔24fを形成している。   As shown in FIGS. 3A, 3B, and 3C, a substantially rectangular parallelepiped stirring protrusion 24c is formed from the back side to the front side at the top where the left and right side surfaces 24a, 24b of the baffle 24 intersect. Yes. The inside of the baffle 24 has a hollow shape, and a plurality of conduction holes 24f are formed on the top surface of the stirring protrusion 24c and communicated with the hollow portion inside.

この構成によれば、洗濯時にバッフル24がドラムの下方にあるときに、洗濯液を中空の内部に溜め、バッフル24が回転しながら上方に移動する際に洗濯液は撹拌突起24c内に集まり、複数の導通孔24fに洗濯液を集中して突出することができる。これにより、洗濯物の上方より大量の洗濯液を供給することが可能となり、洗濯物の濡れ速度を速め、さらに洗浄力を向上させることができる。   According to this configuration, when the baffle 24 is below the drum during washing, the washing liquid is stored inside the hollow, and when the baffle 24 moves upward while rotating, the washing liquid gathers in the stirring protrusion 24c, The washing liquid can be concentrated and protruded into the plurality of conduction holes 24f. Thereby, it becomes possible to supply a large amount of washing liquid from above the laundry, thereby increasing the wetting speed of the laundry and further improving the cleaning power.

尚、上記構成において、導通孔24fは撹拌突起24cの天面のみに形成されているが、撹拌突起24cに導通孔があれば、撹拌突起24cの周囲にも導通孔を形成していてもよい。   In the above configuration, the conduction hole 24f is formed only on the top surface of the stirring protrusion 24c. However, if the stirring protrusion 24c has a conduction hole, a conduction hole may also be formed around the stirring protrusion 24c. .

(実施の形態4)
上記実施の形態1〜3については、ドラム式洗濯機について説明を行ったが、本発明は、乾燥機能を有するドラム式洗濯乾燥機についても有効な効果を得ることができる。
(Embodiment 4)
In the first to third embodiments, the drum type washing machine has been described. However, the present invention can obtain an effective effect even for a drum type washing machine having a drying function.

以下、ドラム式洗濯乾燥機における乾燥行程での実施の形態を図1および図2を参照して説明する。   Hereinafter, an embodiment in a drying process in the drum type washing and drying machine will be described with reference to FIGS. 1 and 2.

図1において、洗濯行程のあとは、図示しない乾燥ファンとヒーターによって、回転ドラム内に温風が吹き込まれ、モータ7により回転ドラム2が回転駆動されて乾燥行程が開始される。回転ドラム2の回転により、回転ドラム2内に収容された洗濯物は回転ドラム2の内周面に設けられたバッフル4によって回転方向に持ち上げられ、持ち上げられた適当な高さ位置から落下する撹拌動作が繰り返されるので、洗濯物には温風により水分を蒸発させながら、乾燥がなされる。   In FIG. 1, after the washing process, warm air is blown into the rotating drum by a drying fan and a heater (not shown), and the rotating drum 2 is driven to rotate by the motor 7 to start the drying process. By the rotation of the rotating drum 2, the laundry accommodated in the rotating drum 2 is lifted in the rotating direction by the baffle 4 provided on the inner peripheral surface of the rotating drum 2, and agitated by dropping from the lifted appropriate height position. Since the operation is repeated, the laundry is dried while water is evaporated by warm air.

このとき、回転ドラム2内で、斜め前方向に持ち上げられる作用が洗濯物に与えられるため、傾斜配置された回転ドラム内の低い背面側の位置に偏って圧迫されてしまうことがなく、洗濯物が回転ドラム2の前後にわたって広がって撹拌されるので、乾燥後の仕上りを向上させることができる。   At this time, since the laundry is lifted obliquely forward in the rotating drum 2, the laundry is not biased to a low back side position in the inclined rotating drum, and the laundry Is spread over the front and rear of the rotary drum 2 and stirred, so that the finish after drying can be improved.

以上のように、本発明にかかるドラム式洗濯機は、回転ドラムを傾斜配置して洗濯物の出し入れを容易にしたドラム式洗濯機において、洗濯時に洗濯物が回転ドラム内の背面側に偏ってしまい洗浄性能が悪くなってしまうといった課題は、バッフルの頂上部を、回転ドラムの内周面に対し回転ドラムの背面側から正面側に向けて高さが低くなるように形成し、バッフルの側面は、回転ドラムの径方向に対し所定の角度を有する平面状とした構成によりによって解決され、洗いむらが少なく、洗浄性能を向上させることが可能となるので、ドラム式洗濯機のみならず、乾燥機能を有するドラム式洗濯乾燥機にも適用できる。   As described above, the drum-type washing machine according to the present invention is a drum-type washing machine in which the rotating drum is arranged at an inclination so that the laundry can be easily taken in and out. The laundry is biased toward the back side in the rotating drum at the time of washing. The problem that the cleaning performance deteriorates is that the top of the baffle is formed so that its height decreases from the inner surface of the rotating drum toward the front side of the rotating drum from the rear side of the rotating drum. Is solved by a flat configuration having a predetermined angle with respect to the radial direction of the rotating drum, and there is less unevenness in washing and it is possible to improve the washing performance. It can also be applied to a drum-type washing and drying machine having a function.
