Description
本発明は、糸くず捕集部を備えた洗濯機に関する。
The present invention relates to a washing machine equipped with a lint collector.
洗濯乾燥機には、内槽の回転軸を設置面に対して略垂直としたタテ型と、水平もしくは若干傾斜させたドラム式がある。例えば、ドラム式洗濯機では、洗濯液を汲み上げて洗濯物にかけることで、洗剤等が溶けた洗濯水を洗濯物に満遍なく浸透させる。このように、ドラム式洗濯機は、タンブリング動作や循環ポンプによる洗濯水の循環等により洗濯を行っている。洗濯行程では布が擦れることにより、糸くず(リント)が発生する。
There are two types of washer-dryers: vertical, in which the rotation axis of the inner tub is roughly perpendicular to the surface on which it is placed, and drum, which is horizontal or slightly tilted. For example, in drum-type washing machines, the washing liquid is pumped up and poured onto the laundry, allowing the water containing dissolved detergent to soak evenly into the laundry. In this way, drum-type washing machines wash clothes by tumbling and circulating the wash water with a circulation pump. During the washing process, the fabric rubs against each other, generating lint.
従来の洗濯機には、糸くずを捕集する構造を有するものもある。発生する糸くずには、マイクロプラスチックやマイクロファイバー等の微小なプラスチックが含まれるが、これらは微小なサイズのため、従来のフィルタでは、メッシュサイズが大きく、これらを捕集することは困難であった。捕集量を増やすためにメッシュサイズを小さくすると、糸くずが溜まることによる排水時間の延長の課題があった。
Some conventional washing machines have a structure that captures lint. The lint that is generated contains tiny plastic particles such as microplastics and microfibers, but because these are so tiny, conventional filters have a large mesh size and it is difficult to capture them. If the mesh size is reduced to increase the amount of particles captured, there is the issue of extended drain time due to the accumulation of lint.
そこで、ドラム式洗濯機の構造として特許文献1では、外槽底部の排水口から洗濯水を吸引し、再び回転ドラム内に戻す循環ポンプのポンプ吸入管内に構成した弾力性と可撓性のメッシュフィルターと、排水口から機外に洗濯水を排出する排水弁とを備え、メッシュフィルターは、リントの捕集時に循環ポンプの吸引力により凹状に変形し、循環ポンプの停止により正規形状に復元する弾力性で付着したリントを離脱させ、所定時間排水弁を開放し、洗濯水の排水でリントを排出する事により、捕集したリント除去処理をメンテナンスフリーとし、毎排水時にメッシュフィルターへのリント付着がない初期状態に復帰させる構造が提案されている。
Patent Document 1 proposes a structure for a drum-type washing machine that includes an elastic and flexible mesh filter configured in the pump suction pipe of a circulation pump that sucks in wash water from a drain port at the bottom of the outer tub and returns it to the rotating drum, and a drain valve that discharges wash water outside the machine from the drain port. The mesh filter deforms into a concave shape due to the suction force of the circulation pump when collecting lint, and when the circulation pump is stopped, it returns to its normal shape, allowing the attached lint to detach due to its elasticity. The drain valve is opened for a specified time, and the lint is discharged by draining the wash water, making the collected lint removal process maintenance-free, and the mesh filter returns to its initial state with no lint attached every time it is drained.
また、特許文献2では、洗濯槽および外槽を含み、外槽の排水口と外槽の給水口との間に循環管路が設置され、前記循環管路に排水ポンプおよび主ろ過器が設けられる。前記循環管路にさらに前置ろ過器が設置され、前置ろ過器は排水ポンプと主ろ過器との間に位置し、前置ろ過器のフィルタの緻密度は主ろ過器のフィルタの緻密度より低い構造が提案されている。
Patent Document 2 also proposes a structure that includes a washing tub and an outer tub, a circulation line is installed between the drain outlet of the outer tub and the water supply port of the outer tub, and a drain pump and a main filter are provided in the circulation line. A pre-filter is further installed in the circulation line, and is located between the drain pump and the main filter, and the filter density of the pre-filter is lower than that of the main filter.
しかしながら、特許文献1に記載の洗濯機では、排水口にリント(糸くず)を流すため排水口が詰まる恐れがある。排水口が詰まることにより、排水時間が延びる恐れがある。また、そのままリントを排水するため、リントが捕集できず、洗濯機からリントが下水に放出してしまう。
However, in the washing machine described in Patent Document 1, lint is flushed down the drain, which can cause the drain to become clogged. A clogged drain can cause the drain time to increase. In addition, because the lint is flushed directly down the drain, it cannot be captured and ends up being released into the sewer from the washing machine.
特許文献2に記載の洗濯機では、前置ろ過器まで排水ポンプで吸引して初期ろ過を行った後に、主ろ過器まで排水ポンプで吸引して高度ろ過を行っているため、排水時間が従来よりも長くなる恐れがあった。
In the washing machine described in Patent Document 2, the drain pump sucks water up to the pre-filter to perform initial filtration, and then the drain pump sucks water up to the main filter to perform advanced filtration, so there is a risk that the drain time will be longer than before.
本発明は、前記した従来の課題を解決するものであり、糸くずを捕集し、排水時間の遅延を抑制することが可能な洗濯機を提供することを目的とする。
The present invention aims to solve the above-mentioned problems of the conventional washing machine by providing a washing machine that can collect lint and reduce delays in draining time.
前記課題を解決するため、本発明の洗濯機は、洗濯槽と、洗濯槽から排水口へと流れる排水経路と、前記洗濯槽から洗濯水を循環させる循環経路と、前記循環経路または前記排水経路に糸くずを捕集する糸くず捕集部と、を備え、前記糸くず捕集部は、第一のフィルタと、第二のフィルタとで構成され、前記第二のフィルタで捕集した糸くずは、糸くず捕集時の水の流れとは略逆方向の水の流れにより除去されるようにした。
In order to solve the above problem, the washing machine of the present invention comprises a washing tub, a drainage path that flows from the washing tub to a drain outlet, a circulation path that circulates the washing water from the washing tub, and a lint collection section that collects lint in the circulation path or the drainage path, the lint collection section being composed of a first filter and a second filter, and the lint collected by the second filter is removed by a water flow in a direction substantially opposite to the water flow when collecting the lint.
本発明によれば、糸くずを捕集し、排水時間の遅延を抑制することが可能な洗濯機を提供できる。
The present invention provides a washing machine that can collect lint and reduce delays in draining time.
以下、本発明の実施形態について、図面を参照しながら詳細に説明するが、本発明は以下の実施形態に限定されることなく、本発明の技術的な概念の中で種々の変形例や応用例もその範囲に含むものである。
Below, an embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiment, and various modifications and application examples within the technical concept of the present invention are also included in its scope.
図1は、本発明の第1実施形態のドラム式洗濯機の概略構成図である。なお、図1に示す洗濯機は、第1実施形態において、必要最低限な主要部のみを示した概略図である。
FIG. 1 is a schematic diagram of a drum-type washing machine according to a first embodiment of the present invention. Note that the washing machine shown in FIG. 1 is a schematic diagram showing only the minimum essential parts of the first embodiment.
図1に示すように、ドラム式洗濯機(以下、洗濯機と略記する)は、筐体3の内側に外槽2が備えられ、外槽2の内側に洗濯物7が投入される内槽1(ドラム)が備えられて構成されている。内槽1の回転軸は、前側が後ろ側よりも高くなるように傾斜し、または略水平となるように構成されている。
また本実施形態では、外槽2と内槽1によって洗濯槽が構成されている。 As shown in Fig. 1, a drum-type washing machine (hereinafter, simply referred to as a washing machine) is configured to include anouter tub 2 inside a housing 3, and an inner tub 1 (drum) into which laundry 7 is placed inside the outer tub 2. The rotation axis of the inner tub 1 is inclined so that the front side is higher than the rear side, or is configured to be approximately horizontal.
In this embodiment, theouter tub 2 and the inner tub 1 form a washing tub.
また本実施形態では、外槽2と内槽1によって洗濯槽が構成されている。 As shown in Fig. 1, a drum-type washing machine (hereinafter, simply referred to as a washing machine) is configured to include an
In this embodiment, the
外槽2と内槽1に間には空間が設けられ、その間を水が通り抜けられるようになっている。また、外槽2の下部には洗濯水が供給され、循環ポンプ4を用いて、循環流路9を通って内槽1に戻ることで循環するようになっている。
A space is provided between the outer tub 2 and the inner tub 1, allowing water to pass through the space. Washing water is supplied to the bottom of the outer tub 2, and circulated by using the circulation pump 4 to return to the inner tub 1 through the circulation flow path 9.
洗濯機は、糸くず捕集部5を備えている。この糸くず捕集部5は、第1のフィルタ6aと第2のフィルタ6bから構成される。
The washing machine is equipped with a lint collector 5. This lint collector 5 is composed of a first filter 6a and a second filter 6b.
循環流路9は、外槽2の底部と循環ポンプ4の吸引側(入口)とを糸くず捕集部5を介して接続する配管と、循環ポンプ4の吐出側(出口)とを接続する配管と、を備えて構成されている。
The circulation flow path 9 is configured with a pipe that connects the bottom of the outer tank 2 to the suction side (inlet) of the circulation pump 4 via the lint collector 5, and a pipe that connects to the discharge side (outlet) of the circulation pump 4.
排水流路10は、洗濯槽から排水口11へと洗濯水またはすすぎ水が流れる流路であり、外槽2の底部と排水口11とを糸くず捕集部5を介して接続する配管を備えている。また、排水流路10には、排水弁8が設けられている。
循環流路9の配管と排水流路10の配管は、外槽2の底部から糸くず捕集部5までの経路が共有され、一本の配管によって構成されている。 Thedrain passage 10 is a passage through which washing water or rinsing water flows from the washing tub to the drain outlet 11, and includes a pipe that connects the bottom of the outer tub 2 to the drain outlet 11 via the lint collector 5. The drain passage 10 is also provided with a drain valve 8.
The piping of thecirculation flow path 9 and the piping of the drainage flow path 10 share a common path from the bottom of the outer tub 2 to the lint trapping section 5, and are configured as a single pipe.
循環流路9の配管と排水流路10の配管は、外槽2の底部から糸くず捕集部5までの経路が共有され、一本の配管によって構成されている。 The
The piping of the
このように構成することで、外槽2の底部からの水(洗濯水またはすすぎ水)の流れは、循環ポンプ4に入る経路と、排水弁8を通して排水口11へ流れる経路となる。糸くず捕集部5は、循環ポンプ4の入口側(吸込側)に設置されている。
With this configuration, the flow of water (washing water or rinsing water) from the bottom of the outer tub 2 enters the circulation pump 4 and flows through the drain valve 8 to the drain outlet 11. The lint collector 5 is installed on the inlet side (suction side) of the circulation pump 4.
糸くず捕集部5には、詳細を後述するが、第1のフィルタ6aと第2のフィルタ6bの捕集フィルタが設けられている。これらの捕集フィルタは洗濯物7から発生した糸くず(マイクロプラスチックはマイクロファイバーを含む)を捕集し、排水口11に糸くずが流れることを防止する機能を有する。糸くずは、洗濯や乾燥時に衣類が擦れることにより発生する。
The lint collection section 5 is provided with a first filter 6a and a second filter 6b, the details of which will be described later. These collection filters have the function of collecting lint (microplastics include microfibers) generated from the laundry 7 and preventing the lint from flowing into the drain 11. Lint is generated by the friction of clothes during washing and drying.
糸くずが捕集フィルタに溜まってくると、糸くずが圧力損失となり、排水時間が延びる恐れがあることから、実施形態の糸くず捕集部5を、つぎのように構成して排水時間の延長を抑制する。
When lint accumulates in the collection filter, it can cause pressure loss and extend the drainage time, so the lint collection unit 5 of this embodiment is configured as follows to prevent the drainage time from being extended.
図2Aは、糸くず捕集部5の鉛直方向の縦断面図である。糸くず捕集部5は、鉛直方向の上部に、外槽2(図1参照)の底部からの洗濯水(すすぎ水)が流入する流入口を設け、鉛直方向の底部に、循環ポンプ4(図1参照)に洗濯水(すすぎ水)を流出する流出口と、排水口11(図1参照)に洗濯水(すすぎ水)を流出する流出口を設けている。さらに、糸くず捕集部5は、内部に第1のフィルタ6aと第2のフィルタ6bの捕集フィルタを設ける。
Figure 2A is a vertical cross-sectional view of the lint collection unit 5. The lint collection unit 5 has an inlet at the top in the vertical direction through which the washing water (rinse water) flows in from the bottom of the outer tub 2 (see Figure 1), and an outlet at the bottom in the vertical direction through which the washing water (rinse water) flows out to the circulation pump 4 (see Figure 1), and an outlet through which the washing water (rinse water) flows out to the drain port 11 (see Figure 1). Furthermore, the lint collection unit 5 has a first filter 6a and a second filter 6b collection filters inside.
第1のフィルタ6aは、鉛直上方が開いた器型の形状を成す。そして、第1のフィルタ6aの壁面の上方の一部に、第2のフィルタ6bを形成する。
The first filter 6a is shaped like a vessel with an open vertical surface. The second filter 6b is formed on a portion of the upper wall of the first filter 6a.
第1のフィルタ6aと第2のフィルタ6bの捕集フィルタのメッシュサイズは、例えば1μm~3mm、望ましくは、所定量のマイクロプラスチックを捕集することと排水時間を遅延を防止するためには50μm~700μm程度とする。
The mesh size of the collection filters of the first filter 6a and the second filter 6b is, for example, 1 μm to 3 mm, and preferably, approximately 50 μm to 700 μm in order to collect a predetermined amount of microplastics and prevent delays in drainage time.
洗濯水(すすぎ水)は、糸くず捕集部5の鉛直上方から流入し、底部から循環水または排水として流出する。この際、捕集フィルタは、洗濯水(すすぎ水)の糸くずを捕集する。糸くずが捕集フィルタに溜まってくると、糸くずが圧力損失となり、糸くず捕集部5からの流出量が低下し、洗濯機が排水動作の場合には、排水時間が遅延する。
Washing water (rinsing water) flows into the lint collection section 5 from above and flows out from the bottom as circulating water or wastewater. At this time, the collection filter collects lint from the washing water (rinsing water). When lint accumulates in the collection filter, the lint causes a pressure loss, reducing the amount of water flowing out of the lint collection section 5 and delaying the draining time when the washing machine is in the draining operation.
実施形態の糸くず捕集部5では、第1のフィルタ6aの鉛直上方の一部に第2のフィルタ6bを形成するようにし、第1のフィルタ6aに糸くずが溜り、水位が増すと、第2のフィルタ6bも通水する。第2のフィルタ6bの表面には、第1のフィルタ6aの表面よりも糸くずが溜まっていないので、第2のフィルタ6bは第1のフィルタ6aと比較して圧力損失が低く、第2のフィルタ6bを追加して通水することで、排水時間の遅延を抑制することができる。
In the lint collection unit 5 of this embodiment, a second filter 6b is formed vertically above the first filter 6a, and when lint accumulates on the first filter 6a and the water level rises, water also passes through the second filter 6b. Because there is less lint accumulated on the surface of the second filter 6b than on the surface of the first filter 6a, the second filter 6b has a lower pressure loss than the first filter 6a, and by adding the second filter 6b and passing water through it, delays in drainage time can be suppressed.
第1のフィルタ6aと第2のフィルタ6bの捕集フィルタのメッシュサイズは、第1のフィルタ6aと第2のフィルタ6bで同じサイズでも構わないが、第2のフィルタ6bのほうが、第1のフィルタ6aよりもメッシュサイズが大きいほうがよい。第2のフィルタ6bのメッシュサイズを第1のフィルタ6aのメッシュサイズよりも大きくすることにより、圧力損失がより低くなるため、排水時間の遅延をより抑制できる。
The mesh size of the collection filters of the first filter 6a and the second filter 6b may be the same for the first filter 6a and the second filter 6b, but it is preferable that the mesh size of the second filter 6b is larger than that of the first filter 6a. By making the mesh size of the second filter 6b larger than that of the first filter 6a, the pressure loss is reduced, and delays in drainage time can be further suppressed.
また、第2のフィルタ6bは、メッシュ状ではなく、例えば、くし歯状の構造であっても構わない。くし歯状とすることで、マイクロプラスチックの捕集効率は落ちるが、排水時間を遅延することができる。
The second filter 6b may also have a comb-like structure, rather than a mesh-like structure. By using a comb-like structure, the efficiency of capturing microplastics decreases, but the drainage time can be delayed.
捕集フィルタの材質は、ポリエステルやナイロンのような繊維でできているものを用いてもよいが、金属(例えば、銅、ステンレス鋼)でできているものを用いると、微生物が繁殖しづらく衛生的である。
The material of the collection filter may be made of fibers such as polyester or nylon, but if it is made of metal (e.g. copper or stainless steel), it is more hygienic and less likely for microorganisms to grow.
また、金属の捕集フィルタを用いる場合には、網状のものよりも、金属板にエッチングなどで孔を開けたものを用いるとよい。これは捕集フィルタの表面に凹凸(バリのようなもの)が形成されなくなるので、糸が捕集フィルタの表面に絡みにくく、糸くずを廃棄するときに、糸くずがフィルタ表面に残りにくいからである。
Also, when using a metal collection filter, it is better to use a metal plate with holes etched or otherwise made rather than a mesh type. This is because unevenness (such as burrs) will not form on the surface of the collection filter, so the threads are less likely to get tangled on the surface of the collection filter, and the lint is less likely to remain on the filter surface when it is discarded.
また、捕集フィルタの表面は、酸素プラズマはコーティング剤による親水性向上処理を施してもよい。このように親水性向上処理を行うことにより、水が流れやすくなり、排水時間お遅延を防ぐことができる。
The surface of the collection filter may also be treated with oxygen plasma or a coating agent to improve its hydrophilicity. By treating the surface with hydrophilicity in this way, water can flow more easily, preventing delays in drainage time.
上記では、第1のフィルタ6aと第2のフィルタ6bの2つの捕集フィルタを設ける例を説明したが、それ以上あっても構わないし、鉛直上方の捕集フィルタほど糸くずの捕集率が小さくなるように、それぞれのフィルタの素材やメッシュサイズが異なっていても構わない。
In the above, an example was described in which two collection filters, a first filter 6a and a second filter 6b, are provided, but there may be more than one, and the materials and mesh sizes of the filters may be different so that the lint collection rate of the collection filters located vertically higher is smaller.
図2Bは、他の糸くず捕集部5の鉛直方向の縦断面図である。図2Aの糸くず捕集部5とは、第1のフィルタ6aの壁面の上方の全周に、第2のフィルタ6bを形成する。
FIG. 2B is a vertical cross-sectional view of another lint trapping unit 5. The lint trapping unit 5 in FIG. 2A has a second filter 6b formed around the entire upper periphery of the wall surface of the first filter 6a.
これにより、水位が増した際に糸くずの溜まっていない第2のフィルタ6bを追加して通水するので、第1のフィルタ6aの壁面の上方の一部に第2のフィルタ6bを形成する場合よりも、さらに排水時間の遅延を抑制できる。
As a result, when the water level rises, the second filter 6b, which does not contain lint, is added and water passes through it, so the delay in drainage time can be further reduced compared to when the second filter 6b is formed on a portion of the upper wall of the first filter 6a.
つぎに、図3Aと図3Bにより、洗濯機における水の流れを説明する。図3Aは、洗い工程またはすすぎ工程の水(洗濯水または洗い水)の流れを示す模式図である。図3Bは、排水工程の水の流れを示す模式図である。
Next, the flow of water in a washing machine will be explained with reference to Figures 3A and 3B. Figure 3A is a schematic diagram showing the flow of water (washing water or washing water) in the washing process or rinsing process. Figure 3B is a schematic diagram showing the flow of water in the draining process.
なお、図3Aと図3Bでは、鉛直方向に上下に配置される第1のフィルタ6aと第2のフィルタ6bとに、並行して水が通水することがあるため、第1のフィルタ6aと第2のフィルタ6bとを水平方向に配置して示しているにすぎない。第1のフィルタ6aと第2のフィルタ6bとは、物理的には、鉛直方向の上下に配置する。
Note that in Figures 3A and 3B, the first filter 6a and the second filter 6b are merely shown as being arranged in the horizontal direction because water may pass through the first filter 6a and the second filter 6b, which are arranged above and below in the vertical direction, in parallel. The first filter 6a and the second filter 6b are physically arranged above and below in the vertical direction.
まず、図3Aにより、洗い工程またはすすぎ工程の水(洗濯水または洗い水)の流れを説明する。
洗い工程またはすすぎ工程では、不図示の制御部により排水弁8を閉じて、外槽2の水洗濯水または洗い水)が排水口11に流れないようにする。 First, the flow of water (washing water or washing water) in the washing process or rinsing process will be described with reference to FIG. 3A.
During the washing or rinsing process, thedrain valve 8 is closed by a control unit (not shown) to prevent the water (washing water or washing water) from the outer tub 2 from flowing into the drain port 11.
洗い工程またはすすぎ工程では、不図示の制御部により排水弁8を閉じて、外槽2の水洗濯水または洗い水)が排水口11に流れないようにする。 First, the flow of water (washing water or washing water) in the washing process or rinsing process will be described with reference to FIG. 3A.
During the washing or rinsing process, the
外槽2の水は、外槽2の底部から糸くず捕集部5に流入し、糸くず捕集部5を通水した水は、循環ポンプ4に流入する。そして、制御部により循環ポンプ4が駆動され、水は、循環ポンプ4により外槽2に給水される。このようにして、水は、外槽2と糸くず捕集部5と循環ポンプ4を循環する。
Water in the outer tub 2 flows into the lint collection section 5 from the bottom of the outer tub 2, and the water that has passed through the lint collection section 5 flows into the circulation pump 4. The control unit then drives the circulation pump 4, which supplies water to the outer tub 2. In this way, the water circulates between the outer tub 2, the lint collection section 5, and the circulation pump 4.
循環している水に含まれる糸くずは、水が糸くず捕集部5の第1のフィルタ6aと第2のフィルタ6b(主に、第1のフィルタ6a)を通水する際に捕集される。
The lint contained in the circulating water is collected as the water passes through the first filter 6a and the second filter 6b (mainly the first filter 6a) of the lint collection unit 5.
つぎに、図3Bにより、排水工程の水(洗濯水または洗い水)の流れを説明する。
排水工程では、不図示の制御部により排水弁8を開けて、外槽2の水洗濯水または洗い水)を排水口11に流す。 Next, the flow of water (washing water or rinse water) in the draining process will be described with reference to FIG. 3B.
In the drainage process, thedrain valve 8 is opened by a control unit (not shown) to allow the water (washing water or rinse water) in the outer tub 2 to flow into the drain outlet 11.
排水工程では、不図示の制御部により排水弁8を開けて、外槽2の水洗濯水または洗い水)を排水口11に流す。 Next, the flow of water (washing water or rinse water) in the draining process will be described with reference to FIG. 3B.
In the drainage process, the
外槽2の水は、外槽2の底部から糸くず捕集部5に流入し、糸くず捕集部5を通水した水は、排水弁8に流入する。そして、制御部により開けられた排水弁8を通水して、排水口11に流出する。このようにして、外槽2の水は、排水口11に流出する。
The water in the outer tub 2 flows into the lint collector 5 from the bottom of the outer tub 2, and after passing through the lint collector 5, it flows into the drain valve 8. The water then passes through the drain valve 8, which is opened by the control unit, and flows out to the drain port 11. In this way, the water in the outer tub 2 flows out to the drain port 11.
外槽2の水に含まれる糸くずは、水が糸くず捕集部5の第1のフィルタ6aと第2のフィルタ6bを通水する際に捕集される。この際、捕集した糸くずにより圧力損失が増大した第1のフィルタ6aにより水位が増すと、第1のフィルタ6aの上方に設けられ、糸くずの溜まっていないか、または、メッシュサイズよりも大きな第2のフィルタ6bからも通水する。これにより、水の排水時間の遅延を抑制する。
The lint contained in the water in the outer tub 2 is collected when the water passes through the first filter 6a and the second filter 6b of the lint collection unit 5. At this time, if the water level rises due to the first filter 6a increasing the pressure loss caused by the collected lint, water will also pass through the second filter 6b, which is located above the first filter 6a and has no lint or a larger mesh size than the first filter 6a. This prevents delays in the water drainage time.
つぎに、第2実施形態のドラム式洗濯機(以下、洗濯機と略記する)の概略構成図を図4に示す。
図4の洗濯機は、循環ポンプ4の出口側の一部バイパスさせるバイパス流路13をつくり、第2のフィルタ6bに溜まった糸くずを移動させるようにしたことが、図1に示した洗濯機と異なる。 Next, a schematic configuration diagram of a drum type washing machine (hereinafter, abbreviated as washing machine) according to a second embodiment is shown in FIG.
The washing machine of FIG. 4 differs from the washing machine of FIG. 1 in that abypass flow path 13 is provided to bypass a part of the outlet side of the circulation pump 4, and the lint accumulated in the second filter 6b is moved.
図4の洗濯機は、循環ポンプ4の出口側の一部バイパスさせるバイパス流路13をつくり、第2のフィルタ6bに溜まった糸くずを移動させるようにしたことが、図1に示した洗濯機と異なる。 Next, a schematic configuration diagram of a drum type washing machine (hereinafter, abbreviated as washing machine) according to a second embodiment is shown in FIG.
The washing machine of FIG. 4 differs from the washing machine of FIG. 1 in that a
図5は、図4の糸くず捕集部5の鉛直方向の縦断面図である。図2Aまたは図2Bで説明した糸くず捕集部5とは、バイパス流路13により第2のフィルタ6bに溜まった糸くずを移動させるように、糸くずを捕集する方向とは逆方向に水(洗濯水またはすすぎ水)を給水する給水口を設けたことが異なる。
Figure 5 is a vertical cross-sectional view of the lint collection unit 5 in Figure 4. It differs from the lint collection unit 5 described in Figure 2A or 2B in that it has a water supply port that supplies water (washing water or rinsing water) in the opposite direction to the lint collection direction so that the lint accumulated in the second filter 6b is moved by the bypass flow path 13.
詳しくは、糸くず捕集部5の捕集フィルタを第1のフィルタ6aと第2のフィルタ6bとに分割することにより、排水が遅延することを防いているが、第1のフィルタ6aに糸くずが沢山溜まってくると、排水時に第2のフィルタ6bにも糸くずが溜まってしまい、排水時間が延びる可能性がある。
To be more specific, by dividing the lint collection filter of the lint collection unit 5 into a first filter 6a and a second filter 6b, delays in drainage are prevented; however, if a large amount of lint accumulates in the first filter 6a, lint may also accumulate in the second filter 6b during drainage, potentially lengthening the drainage time.
この排水遅延を防ぐために、循環ポンプ4の出口側の流路を分岐して、バイパス流路13をつくり、バイパス流路13の水の流れで、第2のフィルタ6bに溜まった糸くずを、器型の形状の第1のフィルタ6aに移動させる。
To prevent this drainage delay, the flow path on the outlet side of the circulation pump 4 is branched off to create a bypass flow path 13, and the water flow in the bypass flow path 13 moves the lint that has accumulated in the second filter 6b to the bowl-shaped first filter 6a.
図5では、糸くず捕集時の水の流れとは略逆方向のバイパス流路13からの水(洗濯水またはすすぎ水)の流れにより除去する様子を示しているが、第2のフィルタ6に溜まった糸くずを器型の形状の第1のフィルタ6aに移動させればよいため、「逆方向」でなくとも、例えばフィルタ面に対して多少斜めに給水してもよい。
Figure 5 shows the removal of lint by water (washing water or rinsing water) flowing from the bypass flow path 13 in a direction roughly opposite to the water flow when collecting lint, but since the lint accumulated in the second filter 6 only needs to be moved to the bowl-shaped first filter 6a, the water does not have to be supplied in the "opposite direction," and can be supplied, for example, at a slight angle to the filter surface.
つぎに、図6Aと図6Bにより、洗濯機における水の流れを説明する。図6Aは、洗い工程またはすすぎ工程の水(洗濯水または洗い水)の流れを示す模式図である。図6Bは、排水工程の水の流れを示す模式図である。
Next, the flow of water in a washing machine will be explained with reference to Figures 6A and 6B. Figure 6A is a schematic diagram showing the flow of water (washing water or washing water) in the washing process or rinsing process. Figure 6B is a schematic diagram showing the flow of water in the draining process.
まず、図6Aにより、洗い工程またはすすぎ工程の水(洗濯水または洗い水)の流れを説明する。
洗い工程またはすすぎ工程では、不図示の制御部により排水弁8を閉じて、外槽2の水洗濯水または洗い水)が排水口11に流れないようにする。 First, the flow of water (washing water or washing water) in the washing process or rinsing process will be described with reference to FIG. 6A.
During the washing or rinsing process, thedrain valve 8 is closed by a control unit (not shown) to prevent the water (washing water or washing water) from the outer tub 2 from flowing into the drain port 11.
洗い工程またはすすぎ工程では、不図示の制御部により排水弁8を閉じて、外槽2の水洗濯水または洗い水)が排水口11に流れないようにする。 First, the flow of water (washing water or washing water) in the washing process or rinsing process will be described with reference to FIG. 6A.
During the washing or rinsing process, the
外槽2の水は、外槽2の底部から糸くず捕集部5に流入し、糸くず捕集部5を通水した水は、循環ポンプ4に流入する。そして、制御部により循環ポンプ4が駆動され、水は、循環ポンプ4により外槽2に給水される。この際に、バイパス流路13を経由して循環ポンプ4の吐出水の一部が第2のフィルタ6bに給水される。このようにして、水は、外槽2と糸くず捕集部5と循環ポンプ4を循環する。
Water in the outer tub 2 flows into the lint collection section 5 from the bottom of the outer tub 2, and the water that has passed through the lint collection section 5 flows into the circulation pump 4. The control unit then drives the circulation pump 4, which supplies water to the outer tub 2. At this time, a portion of the water discharged from the circulation pump 4 is supplied to the second filter 6b via the bypass flow path 13. In this way, the water circulates between the outer tub 2, the lint collection section 5, and the circulation pump 4.
循環している水に含まれる糸くずは、主に、糸くず捕集部5の第1のフィルタ6aを通水する際に捕集される。第2のフィルタ6bに溜まっている糸くずは、バイパス流路13を経由して逆方向に通水する水により、器型の形状の第1のフィルタ6aに移動する。
The lint contained in the circulating water is mainly collected when the water passes through the first filter 6a of the lint collection unit 5. The lint that has accumulated in the second filter 6b is transferred to the bowl-shaped first filter 6a by the water passing in the opposite direction via the bypass flow path 13.
つぎに、図6Bにより、排水工程の水(洗濯水または洗い水)の流れを説明する。
排水工程では、不図示の制御部により排水弁8を開けて、外槽2の水洗濯水または洗い水)を排水口11に流す。 Next, the flow of water (washing water or rinse water) in the draining process will be described with reference to FIG. 6B.
In the drainage process, thedrain valve 8 is opened by a control unit (not shown) to allow the water (washing water or rinse water) in the outer tub 2 to flow into the drain outlet 11.
排水工程では、不図示の制御部により排水弁8を開けて、外槽2の水洗濯水または洗い水)を排水口11に流す。 Next, the flow of water (washing water or rinse water) in the draining process will be described with reference to FIG. 6B.
In the drainage process, the
外槽2の水は、外槽2の底部から糸くず捕集部5に流入し、糸くず捕集部5を通水した水は、排水弁8に流入する。そして、制御部により開けられた排水弁8を通水して、排水口11に流出する。このようにして、外槽2の水は、排水口11に流出する。
The water in the outer tub 2 flows into the lint collector 5 from the bottom of the outer tub 2, and after passing through the lint collector 5, it flows into the drain valve 8. The water then passes through the drain valve 8, which is opened by the control unit, and flows out to the drain port 11. In this way, the water in the outer tub 2 flows out to the drain port 11.
外槽2の水に含まれる糸くずは、水が糸くず捕集部5の第1のフィルタ6aと第2のフィルタ6bを通水する際に捕集される。この際、捕集した糸くずにより圧力損失が増大した第1のフィルタ6aより水位が増すと、第1のフィルタ6aの上方に設けられ、糸くずの溜まっていないか、または、メッシュサイズよりも大きな第2のフィルタ6bからも通水する。これにより、水の排水時間の遅延を抑制する。
The lint contained in the water in the outer tub 2 is collected when the water passes through the first filter 6a and the second filter 6b of the lint collection unit 5. At this time, if the water level rises above the first filter 6a, where the pressure loss has increased due to the collected lint, water will also pass through the second filter 6b, which is located above the first filter 6a and has no lint or a larger mesh size. This prevents delays in the time it takes for the water to drain.
水の循環時(洗い工程またはすすぎ工程)では、糸くずは第一フィルタにたまり、排水時(排水工程)では、第1のフィルタ6aにはすでに糸くずが入っている状態であるため、第2のフィルタの6bの表面にも水の流れに沿って糸くずが溜まる。
When the water is circulating (washing or rinsing process), lint accumulates in the first filter, and when the water is drained (draining process), since lint is already in the first filter 6a, lint also accumulates on the surface of the second filter 6b along with the water flow.
しかし、次に循環した場合(洗い工程またはすすぎ工程)に、循環ポンプ4の出口側からの水の流れを用いて、第2のフィルタ6bの略逆方向に水を流すことにより、第2のフィルタ6bの表面に溜まった糸くずは、第1のフィルタ6aの方向に流れる。したがって、その後の排水(排水工程)では、第2のフィルタ6bには糸くずが溜まっていない状態から排水を開始できるため、排水時間の遅延を防ぐことができる。
However, the next time it is circulated (washing process or rinsing process), the water flow from the outlet side of the circulation pump 4 is used to flow water in approximately the opposite direction to the second filter 6b, so that the lint that has accumulated on the surface of the second filter 6b flows in the direction of the first filter 6a. Therefore, in the subsequent drainage (drainage process), drainage can begin when there is no lint accumulated on the second filter 6b, preventing delays in drainage time.
そして、排水(排水工程)では、第2のフィルタ6bの表面に、また糸くずが溜まるが、次の水の循環時(洗い工程またはすすぎ工程)に、循環ポンプ4aの流れで、第2のフィルタ6bの表面の糸くずを移動させる。これを繰り返すことで、第2のフィルタ6bの表面に糸くずがない状態を作り出すことができるため、排水時間の遅延を防ぐことができる。
Then, during drainage (drainage process), lint accumulates again on the surface of the second filter 6b, but when the water is next circulated (washing process or rinsing process), the flow of the circulation pump 4a moves the lint off the surface of the second filter 6b. By repeating this process, a lint-free state can be created on the surface of the second filter 6b, preventing delays in drainage time.
バイパス流路13の流量は、洗濯槽に戻る循環流路の流量減少を抑えることが望ましく、バイパス流路13の流量は、1~5L/min程度が良い。
The flow rate of the bypass flow path 13 should be set to suppress any decrease in the flow rate of the circulation flow path that returns to the washing tub, and the flow rate of the bypass flow path 13 should be set to approximately 1 to 5 L/min.
つぎに、本発明の第3実施形態のドラム式洗濯機(以下、洗濯機と略記する)の概略構成図を図7に示す。
図7の洗濯機は、循環ポンプ4の出口側の一部バイパスさせるバイパス流路13にバイパス流路弁14を設けて、必要に応じて水を流すようにしたことが、図4に示した洗濯機と異なる。 Next, a schematic configuration diagram of a drum type washing machine (hereinafter, abbreviated as washing machine) according to a third embodiment of the present invention is shown in FIG.
The washing machine in FIG. 7 differs from the washing machine in FIG. 4 in that abypass flow passage 13 that bypasses a portion of the outlet side of the circulation pump 4 is provided with a bypass flow passage valve 14 to allow water to flow as required.
図7の洗濯機は、循環ポンプ4の出口側の一部バイパスさせるバイパス流路13にバイパス流路弁14を設けて、必要に応じて水を流すようにしたことが、図4に示した洗濯機と異なる。 Next, a schematic configuration diagram of a drum type washing machine (hereinafter, abbreviated as washing machine) according to a third embodiment of the present invention is shown in FIG.
The washing machine in FIG. 7 differs from the washing machine in FIG. 4 in that a
ユーザが糸くず捕集部5に溜まった糸くずを捨てた後の、第1のフィルタ6aに糸くずがあまり溜まっていない状態では、バイパス流路13によって第2のフィルタ6bに溜まった糸くずを移動させなくても、排水時間は遅延しない。このため、水の循環時(洗い工程またはすすぎ工程)で、バイパス流路13に水を流さなくてもよいため、バイパス流路弁14は閉じておく。
After the user discards the lint that has accumulated in the lint collector 5, when there is not much lint remaining in the first filter 6a, the drain time is not delayed even if the lint that has accumulated in the second filter 6b is not moved by the bypass flow path 13. Therefore, when circulating water (in the washing or rinsing process), there is no need to flow water through the bypass flow path 13, so the bypass flow path valve 14 is kept closed.
溜まった糸くずの量を計測することにより糸くず捕集部5(第1のフィルタ6a)に糸くずが溜まってきたと判定した場合に、水の循環時(洗い工程またはすすぎ工程)で、バイパス流路弁14を開けてバイパス流路13に水を流し、第2のフィルタ6bに給水する。
If it is determined by measuring the amount of accumulated lint that lint has accumulated in the lint collection unit 5 (first filter 6a), during water circulation (washing process or rinsing process), the bypass flow path valve 14 is opened to allow water to flow into the bypass flow path 13 and supply water to the second filter 6b.
より簡便には、ユーザーが糸くずを捨てた時に値をリセットし、そこからの洗濯回数を制御部にカウントしておき、例えば洗濯回数が10回になったら、バイパス流路弁14を開けて、バイパス流路13に水を流すようにするとよい。
More simply, the value can be reset when the user discards the lint, and the number of washes from that point can be counted in the control unit. For example, when the number of washes reaches 10, the bypass flow path valve 14 can be opened to allow water to flow through the bypass flow path 13.
バイパス流路13に水を流している場合には、循環流路9の流量をバイパス流路弁14を閉じた状態と同じにするために、循環ポンプ4の回転数を変えて、流量を増やすようにしてもよい。循環流路9の流量減少を防ぐことができるため、洗浄能力の減少を防止することができる。また第1のフィルタ6aに糸くずが溜まっていない状態では、循環ポンプ4の回転数を低くすることができるので、消費電力を抑えられる。
When water is flowing through the bypass flow path 13, the rotation speed of the circulation pump 4 may be changed to increase the flow rate in the circulation flow path 9 so that the flow rate is the same as when the bypass flow path valve 14 is closed. This prevents a decrease in the flow rate in the circulation flow path 9, and therefore prevents a decrease in cleaning capacity. In addition, when no lint has accumulated in the first filter 6a, the rotation speed of the circulation pump 4 can be lowered, thereby reducing power consumption.
上記により、より効果的に第2のフィルタ6bに溜まって糸くずを除去することができ、排水時間の遅延を抑制することができる。
As a result, lint that accumulates in the second filter 6b can be removed more effectively, minimizing delays in drainage time.
上記では、バイパス流路弁14を開いて水(洗濯水または洗い水)を第2のフィルタ6bに給水する例を説明したが、不図示の洗濯機の給水弁を開いて水道水を第2のフィルタ6bに給水するようにしてもよい。
In the above, an example has been described in which the bypass flow passage valve 14 is opened to supply water (washing water or cleaning water) to the second filter 6b, but it is also possible to open a water supply valve of the washing machine (not shown) to supply tap water to the second filter 6b.
上記の実施形態では、ドラム式洗濯機を説明したが、つぎに、本発明を縦型洗濯機に適用した例を、図8により説明する。
図8は、第4実施形態の縦型洗濯機(以下、洗濯機と略記する)の概略構成図である。 In the above embodiment, a drum type washing machine has been described. Next, an example in which the present invention is applied to a vertical washing machine will be described with reference to FIG.
FIG. 8 is a schematic diagram of a vertical washing machine (hereinafter, abbreviated as washing machine) according to the fourth embodiment.
図8は、第4実施形態の縦型洗濯機(以下、洗濯機と略記する)の概略構成図である。 In the above embodiment, a drum type washing machine has been described. Next, an example in which the present invention is applied to a vertical washing machine will be described with reference to FIG.
FIG. 8 is a schematic diagram of a vertical washing machine (hereinafter, abbreviated as washing machine) according to the fourth embodiment.
排水流路10は、洗濯槽(外槽2)から排水口11へ、排水(洗濯水またはすすぎ水)が流れる流路であり、外槽2の底部と排水口11とを糸くず捕集部5を介して接続する配管を備えている。また、排水流路10には糸くず捕集部5の下流側に排水弁8が設けられ、排水弁8の開閉により、排水の流れを制御する。
The drainage flow path 10 is a flow path through which drainage water (washing water or rinsing water) flows from the washing tub (outer tub 2) to the drain outlet 11, and is equipped with piping that connects the bottom of the outer tub 2 to the drain outlet 11 via the lint collector 5. In addition, the drainage flow path 10 is provided with a drain valve 8 downstream of the lint collector 5, and the flow of drainage water is controlled by opening and closing the drain valve 8.
糸くず捕集部5は、外槽2の底部の鉛直方向の下側に設置され、鉛直上方が開いた器型の形状を成す第1のフィルタ6aと、第1のフィルタ6aの壁面の上方の一部に形成された第2のフィルタ6bとの捕集フィルタを設け、外槽2の底部から糸くず捕集部5に流入した排水を捕集フィルタを通水して排水するようにし、排水に含まれる糸くずを捕集する。
The lint collection unit 5 is installed vertically below the bottom of the outer tub 2 and is equipped with a collection filter consisting of a first filter 6a that is shaped like a bowl and opens vertically upward, and a second filter 6b that is formed on an upper part of the wall surface of the first filter 6a. Wastewater that flows into the lint collection unit 5 from the bottom of the outer tub 2 is drained by passing it through the collection filter, thereby capturing the lint contained in the wastewater.
糸くずが捕集フィルタに溜まってくると、糸くずが圧力損失となり、糸くず捕集部5からの流出量が低下し、排水時間が遅延する。このため、糸くず捕集部5は、図5で説明した糸くず捕集部5と同様に、第2のフィルタ6bに溜まった糸くずを器型の形状の第1のフィルタ6aに移動するように、排水の糸くずを捕集する方向とは逆方向に第2のフィルタ6bに水を通水するための水の給水口を設ける。
When lint accumulates in the collection filter, the lint causes a pressure loss, reducing the amount of water flowing out of the lint collection unit 5 and delaying the drainage time. For this reason, like the lint collection unit 5 described in Figure 5, the lint collection unit 5 has a water inlet for passing water through the second filter 6b in the opposite direction to the direction in which the drainage lint is collected, so that the lint accumulated in the second filter 6b is moved to the bowl-shaped first filter 6a.
この給水口には、内槽1に洗濯水またはすすぎ水として給水する水道水の給水路から分岐した洗浄水流路15から、給水弁16を介して水(洗浄水)が給水する。
洗濯機(縦型洗濯機)の不図示の制御部は、洗い工程またはすすぎ工程で、給水弁16を開けて、水道水を糸くず捕集部5の第2のフィルタ6bに給水し、第2のフィルタ6bに溜まった糸くずを除く。 Water (washing water) is supplied to this water supply port via awater supply valve 16 from a washing water flow path 15 which branches off from a water supply path for city water that is supplied to the inner tub 1 as washing water or rinsing water.
A control unit (not shown) of the washing machine (vertical washing machine) opens thewater supply valve 16 during the washing process or rinsing process to supply tap water to the second filter 6b of the lint collection unit 5 and removes lint accumulated on the second filter 6b.
洗濯機(縦型洗濯機)の不図示の制御部は、洗い工程またはすすぎ工程で、給水弁16を開けて、水道水を糸くず捕集部5の第2のフィルタ6bに給水し、第2のフィルタ6bに溜まった糸くずを除く。 Water (washing water) is supplied to this water supply port via a
A control unit (not shown) of the washing machine (vertical washing machine) opens the
これにより第2のフィルタ6bの糸くずは除去されるので、排水工程で、第1のフィルタ6aが捕集した糸くずにより圧力損失が増大して水位が増しても、糸くずの溜まっていない第2のフィルタ6bからも通水するので、排水時間の遅延を抑制する。
This removes the lint from the second filter 6b, so even if the pressure loss increases due to the lint collected by the first filter 6a during the drainage process, causing the water level to rise, water can still pass through the second filter 6b, which has no lint, minimizing delays in drainage time.
上記では、ドラム式洗濯機または縦型洗濯機の内部に糸くず捕集部5を設置する例を説明したが、糸くず捕集部5を糸くず捕集装置として、洗濯機(ドラム式洗濯機または縦型洗濯機)の外部に設置してもよい。
In the above, an example was described in which the lint collection unit 5 is installed inside a drum-type washing machine or a vertical washing machine, but the lint collection unit 5 may also be installed outside the washing machine (drum-type washing machine or vertical washing machine) as a lint collection device.
図9は、糸くず捕集部5(糸くず捕集装置)を、排水弁8と排水口11の間でドラム式洗濯機の外部に設置した場合の概略構成図である。図9では、ドラム式洗濯機を図示しているが、縦型洗濯機でもよい。
FIG. 9 is a schematic diagram of a lint collector 5 (lint collector) installed outside a drum-type washing machine between the drain valve 8 and the drain outlet 11. Although FIG. 9 shows a drum-type washing machine, it may also be a vertical washing machine.
糸くず捕集部5は、図2Aまたは図2Bで説明した糸くず捕集部5において、洗濯水(すすぎ水)を流出する流出口の除いた構成とする。
The lint collection section 5 is the same as the lint collection section 5 described in FIG. 2A or FIG. 2B, except that the outlet for the wash water (rinse water) is removed.
糸くず捕集部5では、第1のフィルタ6aの鉛直上方の一部に第2のフィルタ6bを形成するようにしているので、第1のフィルタ6aに糸くずが溜り、水位が増すと、第2のフィルタ6bも通水する。第2のフィルタ6bの表面には、第1のフィルタ6aの表面よりも糸くずが溜まっていないので、第2のフィルタ6bは第1のフィルタ6aと比較して圧力損失が低く、第2のフィルタ6bを追加して通水することで、排水時間の遅延を抑制することができる。
In the lint collection section 5, the second filter 6b is formed in a portion vertically above the first filter 6a, so that when lint accumulates in the first filter 6a and the water level rises, water also passes through the second filter 6b. Because there is less lint accumulated on the surface of the second filter 6b than on the surface of the first filter 6a, the second filter 6b has a lower pressure loss than the first filter 6a, and by adding the second filter 6b and passing water through it, delays in drainage time can be suppressed.
また、循環ポンプ4の入口側に、循環ポンプ4に異物が混入して故障することを防ぐために、異物混入防止装置12を設けるとよい。
In addition, a foreign matter prevention device 12 may be provided on the inlet side of the circulation pump 4 to prevent foreign matter from entering the circulation pump 4 and causing it to break down.
本実施形態によれば、洗濯機の外部に糸くず捕集装置(糸くず捕集部5)を設けるので、装置内部に溜まった糸くずの除去が容易になるため、洗濯機のメンテナンスを容易に行うことができる。
In this embodiment, the lint collection device (lint collection unit 5) is provided outside the washing machine, making it easy to remove lint that has accumulated inside the device, and therefore facilitating maintenance of the washing machine.
