Description

本発明は、台所などで発生する厨芥を回転刃で粉砕処理するディスポーザの洗浄方法に関する。 The present invention relates to a disposer cleaning method for crushing cocoons generated in a kitchen or the like with a rotary blade.

ディスポーザは厨房などにおけるシンクの排水口に連結され、前記排水口から投入される厨芥を破砕室の底部に設けられた回転板で受け、この回転板を電動機で回転させて上面に取り付けた打撃刃で破砕するとともに、回転板を囲んで破砕室の底部内壁に設けた固定刃と回転板外周との間で細かく剪断処理して粉砕し、水とともに回転板下方の排出室に落下させ、排出室に連結した排出管から下水管に流出させるようにしている。 The disposer is connected to a sink outlet in a kitchen or the like, and receives the dredging introduced from the outlet with a rotating plate provided at the bottom of the crushing chamber, and rotates the rotating plate with an electric motor and attaches it to the upper surface. And crushing by finely shearing between the fixed blade provided on the inner wall of the bottom of the crushing chamber surrounding the rotating plate and the outer periphery of the rotating plate, and dropping into the discharge chamber below the rotating plate together with water. From the discharge pipe connected to the sewage pipe.

このようなディスポーザでは、排出管を排出室から径方向に取り付けたものが一般的に用いられており（例えば、特許文献１参照）、粉砕された厨芥とくに繊維質の厨芥が排出口などに絡まって円滑な排出ができず、汚れの原因になっている。このため、排出管を接線方向に設けて排出を円滑にするものが実施されている。（特許文献２、特許文献３）
また、破砕室に投入された厨芥は、回転板により遠心力を受けるため、破砕室内には厨芥が飛び散り破砕室内壁を汚染するだけでなく、回転板の周囲と固定刃との間で粉砕された厨芥は排出室に落下し排出室の底面を流れて排出されるので、回転板で仕切られた排出室内にも、粉砕された厨芥や、水に混じって流される油分や洗剤滓などが付着し、汚泥状態になって衛生上好ましくないだけでなく、悪臭を発生する原因になっている。 In such a disposer, a discharge pipe having a discharge pipe attached in a radial direction from the discharge chamber is generally used (see, for example, Patent Document 1), and pulverized soot, in particular, fiber soot is entangled in a discharge port or the like. Smooth discharge, causing dirt. For this reason, a discharge pipe is provided in the tangential direction to facilitate discharge. (Patent Document 2, Patent Document 3)
In addition, since the soot put into the crushing chamber is subjected to centrifugal force by the rotating plate, not only does the spatter scatter in the crushing chamber and contaminate the crushing chamber wall, but it is also crushed between the periphery of the rotating plate and the fixed blade. Since the soot drops into the discharge chamber and flows through the bottom of the discharge chamber, it is discharged into the discharge chamber partitioned by a rotating plate. In addition, it is not preferable in terms of hygiene due to the sludge condition, but it also causes a bad odor.

このため、定期的あるいは不定期に、処理装置内を洗浄する必要があり、とくに家庭用などの小型のディスポーザは、主婦が頻繁に洗浄して清潔に保つようにしている。この洗浄には、破砕室に水を流し込んで水流で洗い流す水洗浄が一般的に行なわれているが、水流だけでは十分な洗浄ができないので、水洗浄に先立ってシンクの排水孔から破砕室内にブラシなどを差し込み、破砕室内壁や回転板上の汚れを落として水洗するようにしているが手間がかかるだけでなく、回転板下面にある排出室は回転板で仕切られているため、ブラシなどの挿入ができず、分解して清掃をしなければならなかった。
なお、回転板下方の排出室を洗浄するために、回転板上部の破砕室を形成するホッパーを取り外し、回転板に設けた孔からブラシ部材を排出室に差し込んで回転板の下面に取り付け、回転板とともにブラシ部材を回転させて排出室内の掃除をするものが提案されているが（特許文献４参照）、ホッパーを取り外さねばならない面倒がある。
また、排出管に三方向切替弁を設け、洗浄時は、排水管を閉塞するとともに別個に設けた逆洗管から処理装置内に逆洗水を厨芥処理時とは逆方向に流入させ、回転板を逆回転させて排出口付近や排出口と切替弁との連結管に付着した厨芥を洗い落とす洗浄装置が提案されている（特許文献１参照）。 For this reason, it is necessary to clean the inside of the processing apparatus regularly or irregularly. Especially, a small-sized disposer for home use is frequently cleaned by a housewife to keep it clean. For this cleaning, water cleaning is generally performed by pouring water into the crushing chamber and rinsing with the water flow. However, since sufficient cleaning cannot be performed with only the water flow, the sink drain hole of the sink leads into the crushing chamber prior to water cleaning. Inserting a brush, etc., and removing dirt on the crushing chamber wall and the rotating plate to wash it with water, it is not only troublesome, but the discharge chamber on the lower surface of the rotating plate is partitioned by the rotating plate, so brushes etc. Could not be inserted and had to be disassembled and cleaned.
To clean the discharge chamber below the rotating plate, remove the hopper that forms the crushing chamber above the rotating plate, insert the brush member into the discharge chamber from the hole provided in the rotating plate, attach it to the lower surface of the rotating plate, and rotate Although the thing which cleans the discharge chamber by rotating a brush member with a board is proposed (refer patent document 4), there exists a troublesome thing which has to remove a hopper.
In addition, a three-way selector valve is provided in the discharge pipe. During cleaning, the drain pipe is closed and backwash water is introduced from the separately provided backwash pipe into the treatment device in the direction opposite to that during dredging. There has been proposed a cleaning device that reversely rotates a plate to wash away soot that adheres to the vicinity of the discharge port or to the connection pipe between the discharge port and the switching valve (see Patent Document 1).

しかし、破砕室に洗浄水を流し込みながら水流のみで洗浄する程度では、内壁に付着して汚泥状になった付着物を効果的に除去できず、シンクの狭い排水口からブラシなどを挿入しても操作が面倒であるだけでなく、ブラシを挿入した状態で誤って回転板を駆動させる危険性もあり、十分な洗浄ができなかった。また、回転板に設けた孔から排出室にブラシ部材を差し込むためには、ホッパーを取り外して回転板上面の孔を露出させる必要があるため、シンクからディスポーザ本体を取り外して分解する手間と大差が無く、主婦らが簡単に実施できるものではなかった。
また、排出管を閉塞させた状態で、排出室内に洗浄水を逆方向から送り込んで回転板を回転させる方法では、三方向切替弁や洗浄水を供給するための逆洗管を別個に設けねばならず、設備が複雑化する欠点があるだけでなく、洗浄中は排出管が閉塞されているため、洗浄中は洗浄で汚れた水が回転板で掻き回されるだけで十分な洗浄が行われない欠点があった。
本発明は、分解を必要としないで通常の運転と同じ方法で水を供給して、破砕室とともに回転板下面の排出室内に水を溜め、汚れた水を排出しながら洗浄し、洗浄した後に破砕室と排出室に溜めた大量の水を急速に流すことにより排出管の洗浄も行なうようにした洗浄方法を提供するものである。 However, it is not possible to effectively remove the sludge adhering to the inner wall by washing with only the water flow while pouring the washing water into the crushing chamber. Insert a brush etc. from the narrow drain outlet of the sink. However, not only was the operation troublesome, but there was also a risk of accidentally driving the rotating plate with the brush inserted, and sufficient cleaning was not possible. Moreover, in order to insert the brush member into the discharge chamber from the hole provided in the rotating plate, it is necessary to remove the hopper and expose the hole on the upper surface of the rotating plate. Neither was it easy for housewives to do.
Also, in the method of rotating the rotating plate by feeding wash water into the discharge chamber from the reverse direction with the discharge pipe closed, a three-way switching valve and a backwash pipe for supplying the wash water must be provided separately. Not only is the equipment complicated, but the discharge pipe is closed during cleaning, so cleaning is performed simply by stirring the dirty water with a rotating plate during cleaning. There was an unfortunate drawback.
The present invention supplies water in the same manner as in normal operation without the need for disassembly, collects water in the discharge chamber on the lower surface of the rotating plate together with the crushing chamber, and cleans and discharges dirty water. The present invention provides a cleaning method in which the discharge pipe is also cleaned by rapidly flowing a large amount of water stored in the crushing chamber and the discharge chamber.

このため、投入口に続く破砕室の底部に突起をそなえた回転板を設け、破砕室内壁に回転板を囲む固定刃をそなえて厨芥を粉砕し、粉砕された厨芥を回転板の周囲から下方の排出室に落下させて排出するディスポーザにおいて、排出室に接続した排出管にエルボ状部を介してトラップをそなえ、洗浄モードでは、回転板を停止させた状態で、破砕室内の回転板上に給水して破砕室と排出室との間の空気通路を一気に塞ぎ、これによって、排出室とトラップ上部のエルボ状部内にあった空気を閉じ込め、閉じ込められた空気の空気圧を利用して破砕室と排出室内に水を溜めさせ、破砕室への給水を続けながら破砕室と排出室内に貯溜した水を回転板の回転によってそれぞれの室内で遠心力を加えて攪拌させ、室内の全面を遠心力で押し付けて急激な水流で洗浄するようにしている。
また、排出室内にインペラをそなえて排出管を接線方向に取り付け、回転板上に給水しながら回転板とインペラを低速で逆回転させ、逆方向のポンプ作用と閉じこめられた空気圧により破砕室から排水室に落ちる水の落下を遅らせて破砕室に水を溜め、給水を続けながら破砕室と排出室に貯溜された水を、回転板の遠心力でそれぞれの室内壁に打ち付けて洗浄させる。
なお、洗浄後に回転板を止め、インペラを正回転させて破砕室に溜めた水を急速に排出させ、排出管内に滞留している厨芥を押し流すことを特徴としている。 For this reason, a rotating plate with a protrusion is provided at the bottom of the crushing chamber following the inlet, and the crushing crust is crushed with a fixed blade surrounding the rotating plate on the crushing chamber wall. In the disposer that drops into the discharge chamber and discharges it, a trap is provided on the discharge pipe connected to the discharge chamber via an elbow-shaped part, and in the cleaning mode, the rotating plate is stopped and placed on the rotating plate in the crushing chamber. Water is supplied to block the air passage between the crushing chamber and the discharge chamber at once, thereby confining the air that was in the elbow-shaped part above the discharge chamber and the trap, and using the air pressure of the trapped air, Water is stored in the discharge chamber, and the water stored in the crushing chamber and the discharge chamber is stirred by applying centrifugal force in each chamber by rotating the rotating plate while continuing to supply water to the crushing chamber. Push and sudden It is as in washing with a water stream.
In addition, an impeller is provided in the discharge chamber, and a discharge pipe is attached in the tangential direction, while rotating the rotating plate and the impeller at low speed while supplying water on the rotating plate, and draining from the crushing chamber by reverse pumping action and confined air pressure. The water falling in the chamber is delayed to accumulate water in the crushing chamber, and the water stored in the crushing chamber and the discharge chamber is washed against each indoor wall by the centrifugal force of the rotating plate while continuing to supply water.
In addition, after washing | cleaning, the rotating plate is stopped, the impeller is rotated forward, the water accumulated in the crushing chamber is rapidly discharged, and the stagnation in the discharge pipe is washed away.

このように本発明は、運転を止めた状態で回転板の上面に給水して破砕室と排出室との空気通路を塞ぎ、排出室とトラップの水面との間の空気を閉じ込めることにより、この空気を利用して破砕室内に水を溜め、十分に溜まった水を給水を続けしながら回転板で急激に回転攪拌し遠心力による水流で洗浄するため、装置を少しも分解する必要がなく、簡単な操作で全く手を汚すことがなく、洗浄した汚水を順次に排出しながら、効率のよい洗浄効果が得られる。
また、回転板下方の排出室にインペラをそなえて排出室の接線方向に排出管を接続し、回転板上に給水を継続しながら回転板とインペラを逆回転させることにより、排出室内からの水の落下を遅らせて破砕室内に水を保持させ、洗浄時間を調整することができる。
また、回転板を停止させて破砕室に給水して排出室内の空気を閉じ込めることにより、破砕室内に大量の水を溜め、この水をインペラの正回転により排出管内に急激に流すことができるので、下水道につながる排出管内に滞留している厨芥やごみを押し流して排出管内を洗浄し、詰まりを解消させる効果を得られる。 As described above, the present invention supplies water to the upper surface of the rotating plate in a state where the operation is stopped, blocks the air passage between the crushing chamber and the discharge chamber, and confines the air between the discharge chamber and the water surface of the trap. Water is accumulated in the crushing chamber using air, and the water that has been sufficiently accumulated is rapidly stirred with a rotating plate and washed with water flow by centrifugal force while continuing to supply water, so there is no need to disassemble the device at all. A simple operation does not contaminate the hands at all, and an efficient cleaning effect can be obtained while sequentially discharging the washed sewage.
In addition, an impeller is provided in the discharge chamber below the rotating plate, a discharge pipe is connected in the tangential direction of the discharging chamber, and water is supplied from the discharge chamber by rotating the rotating plate and the impeller in reverse while continuing water supply on the rotating plate. The water can be held in the crushing chamber by delaying the falling of the water, and the cleaning time can be adjusted.
In addition, by stopping the rotating plate and supplying water to the crushing chamber and confining the air in the discharge chamber, a large amount of water can be stored in the crushing chamber, and this water can be rapidly flowed into the discharge pipe by the forward rotation of the impeller. It is possible to clean the inside of the discharge pipe by washing away the scum and dust remaining in the discharge pipe leading to the sewer, and to obtain an effect of eliminating clogging.

投入口に続く破砕室内の底部に、突起をそなえた回転板と、この回転板の周囲を囲む固定刃をそなえ、粉砕した厨芥を回転板と固定刃との間隙から回転板下方の排出室に落下させて排出するディスポーザにおいて、回転板下方の排出室にインペラをそなえて排出室の接線方向に排出管を接続し、排出室に接続した排出管にエルボ状部を介してトラップをそなえ、回転板上に給水して破砕室と排出室との間の空気通路を塞ぐことにより、排出室と排出管内のトラップ上部にある空気を閉じ込め、水の流出量を制限して破砕室と排出室内に水を溜めるようにしており、給水を継続しながら、破砕室と排出室内に溜まった水を回転板の回転により急激に攪拌させ、遠心力を加えて破砕室および排出室内の全面を洗浄させる。洗浄後はインペラを正回転させることにより、破砕室と排出室内の水をポンプ作用で排出口から排出管内に勢いよく排出させ、トラップおよびトラップから先の排出管内に滞留している粉砕された厨芥などを押し流して排出管内の洗浄を行なわせる。 At the bottom of the crushing chamber following the input port, there is a rotating plate with protrusions and a fixed blade surrounding the rotating plate, and the crushed soot is discharged from the gap between the rotating plate and the fixed blade into the discharge chamber below the rotating plate. In the disposer that drops and discharges, the impeller is attached to the discharge chamber below the rotating plate, the discharge pipe is connected in the tangential direction of the discharge chamber, and the trap is connected to the discharge pipe connected to the discharge chamber via the elbow-shaped part. By supplying water on the plate and closing the air passage between the crushing chamber and the discharge chamber, the air above the trap in the discharge chamber and the discharge pipe is confined, and the amount of water outflow is limited to the crushing chamber and the discharge chamber. The water is stored, and the water accumulated in the crushing chamber and the discharge chamber is rapidly stirred by the rotation of the rotating plate while the water supply is continued, and centrifugal force is applied to wash the entire surface of the crushing chamber and the discharge chamber. After cleaning, the impeller is rotated forward so that the water in the crushing chamber and the discharge chamber is pumped out from the discharge port into the discharge pipe, and the trap and the trapped soot remaining in the previous discharge pipe from the trap Etc. to wash out the discharge pipe.

1 is a side sectional view showing an example of a disposer using the present invention, FIG. 2 is a side sectional view showing a cleaning process, FIG. 3 is a top view showing a bottom portion of a crushing chamber, and FIG. Is a disposer, 2 is a sink, 3 is a drainage port of the sink, 4 is a mounting tube for attaching the disposer 1 to the drainage port 3, and 5 is a lid attached to the drainage port 3, and is attached to the mounting tube 4 as shown in FIG. A plurality of operation modes can be selected depending on the direction. 6 is a slot for the disposer 1, 7 is a crushing chamber following the slot, 8 is a rotating plate provided at the bottom of the crushing chamber 7, 9 is a striking blade attached to the upper surface of the rotating plate 8, and 10 is a rotating plate 8 The fixed blade 11 is fixed to the bottom of the crushing chamber, 11 is a discharge chamber provided below the rotary plate 8, 12 is an impeller attached to the lower surface of the rotary plate 8, 13 is a discharge port, and 14 is a discharge pipe. In the embodiment, as shown in FIG. 3, the discharge port 13 and the discharge pipe 14 are provided in the tangential direction of the discharge chamber 11. The discharge pipe 14 is connected downward through an elbow-like portion 15 and is provided with a trap 16. Reference numeral 17 denotes an electric motor that drives the rotating plate 8.

取付管４の上面には図４に示すように運転モードの指標２０をそなえ、指標の位置に合わせて投入口６の上端部内側にそれぞれ上面に開口する切り欠ぎ溝２１を、外側にセンサー２２（図１）を設けている。蓋５は図５に示すように、通水孔２３と外周面に前記切り欠ぎ溝２１に嵌合する係合突起２４をそなえ、係合突起２４の位置にマグネット２５を埋め込んでいる。
なお、切り欠ぎ溝２１を、上面を覆う溝にして一定角度たとえば２０度ずらせた位置に開口させ、蓋５の係合突起２４を挿入して２０度回動させてマグネット２５をセンサー２２の位置に合わせるようにすることができる。
また、この実施例では排出管１４を接線方向に取り付けているが、径方向に取り付けることもできる。しかし、排出室１１内でインペラ１２によりポンプ作用を有効に行なわせるためには接線方向に取り付けることが望ましい。また、シンク２に水を溜めるときは通水孔のないめくら蓋を用いればよい。 As shown in FIG. 4, the upper surface of the mounting tube 4 is provided with an operation mode index 20, and a notch groove 21 opened on the upper surface inside the upper end portion of the charging port 6 in accordance with the position of the index, and a sensor on the outer side. 22 (FIG. 1) is provided. As shown in FIG. 5, the lid 5 has a water passage hole 23 and an engagement protrusion 24 fitted in the notch groove 21 on the outer peripheral surface, and a magnet 25 is embedded at the position of the engagement protrusion 24.
The notch groove 21 is opened to a position shifted by a certain angle, for example, 20 degrees as a groove covering the upper surface, and the engaging projection 24 of the lid 5 is inserted and rotated 20 degrees to move the magnet 25 of the sensor 22. It can be adapted to the position.
In this embodiment, the discharge pipe 14 is attached in the tangential direction, but it can be attached in the radial direction. However, in order to effectively perform the pump action by the impeller 12 in the discharge chamber 11, it is desirable to attach in the tangential direction. Further, when water is stored in the sink 2, a blind cover without a water passage hole may be used.

ディスポーザで厨芥を処理するとき（バッチ処理の場合を示す）は、投入口６から破砕室７の回転板８上に厨芥を投入し、排水口３から適量の水を供給しながら、係合突起２４を「運転」の指標に合わせて蓋５を装着すると、マグネット２５により「運転」位置のセンサー２２が図示していない制御装置に信号を送って電動機１７を「運転モード」で起動させる。なお、蓋５を挿入した後で水を供給する場合は、蓋５を挿入しても直ちに起動しないように、別に設けた起動スイッチを介して起動させ、あるいはタイマーで僅かな時間をとって起動するようにしておけばよい。 When processing the soot with the disposer (in the case of batch processing), the soot is put on the rotating plate 8 of the crushing chamber 7 from the input port 6 and an appropriate amount of water is supplied from the drain port 3 while engaging projections. When the lid 5 is mounted in accordance with the “driving” index 24, the sensor 22 at the “driving” position sends a signal to a control device (not shown) by the magnet 25 to start the electric motor 17 in the “driving mode”. When water is supplied after the lid 5 is inserted, it is activated via a separate activation switch so that it does not start immediately even if the lid 5 is inserted, or it is activated after a short time with a timer. Just do it.

図６に「運転モード」の制御特性の例を示している。起動当初に低速ｎ１で短時間たとえば２秒の正転（逆転でもよい）を数回（図では３回）繰り返し、金属製異物などが混入していないかを検出する。混入している場合は、回転板８の遠心力で異物が跳ね飛ばされて破砕室７の内壁に当たって衝撃音を発するので、運転を停止させて異物を除去した後に再起動させる。異物が検出されなければ、低速で回転板８を図３の矢印Ａの方向に一定時間ｔ１の連続運転をした後、定格回転数ｎ２に昇速させる。粉砕された厨芥は水とともに排出室１１の排出口１３から矢印Ｂのように排出され、エルボ状部１５を介して排出管１４によりトラップ１６を通って図示しない下水管に放流される。厨芥が粉砕されて電動機の負荷電流が小さくなると電動機１７を停止させる。 FIG. 6 shows an example of the control characteristics of the “operation mode”. At the beginning of activation, a normal rotation (or reverse rotation) of 2 seconds, for example, at a low speed n 1 is repeated several times (three times in the figure) to detect whether or not metal foreign matters are mixed. In the case of contamination, the foreign matter is bounced off by the centrifugal force of the rotating plate 8 and hits the inner wall of the crushing chamber 7 to generate an impact sound. Therefore, the operation is stopped and the foreign matter is removed and then restarted. If the foreign matter is detected, after a continuous operation for a certain time t 1 the rotating plate 8 in the direction of arrow A in FIG. 3 at low speed, it is speed increasing a rated rotational speed n 2. The crushed soot is discharged together with water from the discharge port 13 of the discharge chamber 11 as shown by an arrow B, and is discharged through an elbow-like portion 15 through a trap 16 by a discharge pipe 14 to a sewer pipe (not shown). When the soot is crushed and the load current of the motor becomes small, the motor 17 is stopped.

次に「洗浄モード」について説明する。
図７は制御特性の例を示している。蓋５を「洗浄」の指標に合わせて装着すると、まず低速ｎ１で短時間運転を数回繰り返し、異物が入っていないかを検出する。異物が入っていると回転板の遠心力で跳ね飛ばされ衝撃音を発するので、運転を停止させて異物を取り出す。異物が入っていないことが確認されると、回転板８を停止させ排水口３から回転板８上に水を供給する。
排水口３から供給する水量は、少なくとも回転板８上に落ちた水が、回転板８の周囲にほぼ均等に広がり、あるいは蓋やゴム板の飛散防止具（図示しない）などで水が拡散されて破砕室７の周壁を流れる場合も、ほぼ全周面に流れ、回転板８上および回転板８周囲の固定刃１０との間隙Ｇ（図３）の全面を覆うようにする。 Next, the “cleaning mode” will be described.
FIG. 7 shows an example of control characteristics. When the lid 5 is mounted in accordance with the “cleaning” index, first , a short time operation is repeated several times at a low speed n 1 to detect whether foreign matter is contained. If there is a foreign object, it will be blown off by the centrifugal force of the rotating plate and will make an impact sound, so the operation is stopped and the foreign object is removed. When it is confirmed that no foreign matter is contained, the rotating plate 8 is stopped and water is supplied from the drain port 3 onto the rotating plate 8.
The amount of water supplied from the drain port 3 is that at least the water that has fallen on the rotating plate 8 spreads almost evenly around the rotating plate 8, or the water is diffused by a lid or a rubber plate scattering prevention device (not shown). Even when it flows through the peripheral wall of the crushing chamber 7, it flows on almost the entire peripheral surface so as to cover the entire surface of the gap G (FIG. 3) between the rotating plate 8 and the fixed blade 10 around the rotating plate 8.

回転板８を停止した状態で破砕室７内に給水し、回転板８周囲と固定刃１０との間隙Ｇの全面に水が一気に流れ込んで排出室との空気通路のすべてをほぼ同時に塞ぐと、排出室１１内および排出管１４のトラップ１６の水面Ｗから上のエルボ状部１５内に入っていた空気が閉じ込められる。
空気通路を塞いだ状態のままで給水を続け、破砕室７から間隙Ｇを通って排出室１１に落ちる水で前記閉じ込められた空気Ｒの空間が減少して空気圧が上昇すると、空気Ｒは図２に示すようにエルボ状部１５に押し付けられてトラップ１６の水面Ｗを押し下げるが、同時にエルボ状部１５を通ってトラップ１６に落ちる水の通路が圧縮されてトラップ１６に排出される水量を制限し、破砕室７に供給される水量よりもエルボ状部１５を通る排出水量が少なくなる。また、排出室１１内の空気圧が高くなるので破砕室７から間隙Ｇを通って排出室１１へ落ちる水も幾らか減少する。このため、破砕室７への供給水量と制限された排出水量との差に応じて破砕室７に水を溜めることができる。 When water is supplied into the crushing chamber 7 in a state where the rotating plate 8 is stopped, water flows into the entire surface of the gap G between the rotating plate 8 and the fixed blade 10 and closes all the air passages to the discharge chamber almost simultaneously. Air that has entered the elbow-like portion 15 above the discharge chamber 11 and the water surface W of the trap 16 of the discharge pipe 14 is trapped.
Water supply continues with the air passage closed, and when the space of the trapped air R is reduced by the water falling from the crushing chamber 7 through the gap G to the discharge chamber 11, the air pressure rises. 2, the water surface W of the trap 16 is pushed down by being pressed against the elbow-shaped portion 15, but at the same time, the passage of water that passes through the elbow-shaped portion 15 and falls into the trap 16 is compressed to limit the amount of water discharged to the trap 16. In addition, the amount of water discharged through the elbow-shaped portion 15 is smaller than the amount of water supplied to the crushing chamber 7. Further, since the air pressure in the discharge chamber 11 is increased, the water falling from the crushing chamber 7 through the gap G to the discharge chamber 11 is also somewhat reduced. For this reason, water can be stored in the crushing chamber 7 according to the difference between the amount of water supplied to the crushing chamber 7 and the limited amount of discharged water.

破砕室７内に溜まった水量が増大するとともに、溜まった水の重量で排出室１１へ落ちる水が増え、それに伴って空気圧が増大し空気Ｒがトラップ１６の水面Ｗをさらに押し下げ、水面Ｗがトラップの高さＨだけ下がると、閉じ込められていた空気がトラップから排出されて空気圧が下がり、エルボ状部１５を通る水の制限量が減少して排水量が増大し、破砕室７内に溜まった水の重量と前記排水量の増加で破砕室７から排出室１１に落ちる水の勢いが大きくなり、空気に代わって排出室１１に水が充満し、破砕室７と排出室１１内の水が一体になると、溜まった水の重量で勢いよく排出される。 As the amount of water accumulated in the crushing chamber 7 increases, the amount of water falling into the discharge chamber 11 increases due to the weight of the accumulated water, the air pressure increases accordingly, and the air R further pushes down the water surface W of the trap 16, When the trap height H is lowered, the trapped air is discharged from the trap, the air pressure decreases, the amount of water passing through the elbow-shaped portion 15 is reduced, the amount of drainage is increased, and the air is accumulated in the crushing chamber 7. The momentum of water falling from the crushing chamber 7 to the discharge chamber 11 is increased by the increase in the weight of the water and the amount of drainage, the water is filled in the discharge chamber 11 instead of air, and the water in the crushing chamber 7 and the discharge chamber 11 is integrated. When it becomes, it drains vigorously with the weight of the accumulated water.

水が溜まる速さと量は、ディスポーザの容量、供給水量、回転板と固定刃との隙間Ｇの大きさ、閉じ込められた空気量、トラップの封水の高さＨなどに左右されるが、実験した結果では、家庭用の破砕室容量が１リットル程度の小型のディスポーザでは、毎分８リットルの給水で、回転板周囲の空気通路の閉塞がほぼ一気に行なわれた場合、給水から約１５秒程度で破砕室がほぼ満水になり、２８秒程度でトラップ１６の水面Ｗが折曲がり部まで下がって空気が洩れることが確認された。
この実験は、回転板８を停止した状態で給水するため、排出室１１の排出口を接線方向にした構造やインペラ１２の作用は考慮する必要がなく、排出口１３を径方向に設け、またインペラ１２をそなえていなくても同じ動作が得られる。 The speed and amount of water accumulation depends on the capacity of the disposer, the amount of water supplied, the size of the gap G between the rotating plate and the fixed blade, the amount of trapped air, the height H of the sealed water in the trap, etc. As a result, with a small-sized disposer with a crushing chamber capacity of about 1 liter for home use, when the air passage around the rotating plate is almost closed at a stretch with water supply of 8 liters per minute, about 15 seconds from the water supply. Thus, it was confirmed that the crushing chamber was almost full, and the water surface W of the trap 16 was lowered to the bent portion in about 28 seconds to leak air.
In this experiment, since water is supplied in a state where the rotating plate 8 is stopped, there is no need to consider the structure of the discharge chamber 11 in the tangential direction and the action of the impeller 12, the discharge port 13 is provided in the radial direction, Even if the impeller 12 is not provided, the same operation can be obtained.

したがって、上述の実験結果により、給水によって空気通路が閉塞されて時間ｔ２（前記の実験で約１５秒）を経過し、破砕室７がほぼ満水になったときに電動機１７を定格回転数ｎ２で起動させる。なお、破砕室７に水位センサーを設けて必要な水量になったときに電動機１７を起動させるようにすることもでき、回転数は必ずしも定格回転数の必要はなく、水を攪拌させ遠心力を与えられる回転数であればよい。電動機１７が起動すると回転板８とインペラ１２が回転して、破砕室７および排出室１１内に溜まっている水が遠心力を受けて急激に攪拌され、強い水圧でそれぞれの室内を洗浄する。
このように、破砕室７の水量が所要の量になったときに攪拌を行なうので、洗浄を有効に行なうことができ、排水により破砕室７の水量が減少しても残った水と継続して供給される水が遠心力で内壁に押し付けられて洗浄を続けることができる。
洗浄中に水が破砕室７から排出口１３に排出されることによりトラップ１６の水面Ｗが高さＨまで押し下げられ空気が洩れて排水量の制限がなくなると、洗浄中も排出されていた水量が増えて、大量の水がその重量でトラップ１６を通って急速に排出される。このため、排出室１１が負圧になって破砕室７内の水が排出室１１に噴出して回転板８周囲と固定刃１０との間隙を洗浄するとともに、トラップ１６から先の排出管に大量の排水を生じ排水管内の詰まりを押し流す。 Therefore, according to the above experimental result, when the air passage is blocked by the water supply and the time t 2 (about 15 seconds in the above experiment) has passed and the crushing chamber 7 is almost full, the motor 17 is set to the rated rotational speed n. Start with 2 . It should be noted that a water level sensor is provided in the crushing chamber 7 so that the electric motor 17 can be started when the required amount of water is reached. Any rotational speed may be given. When the electric motor 17 is started, the rotating plate 8 and the impeller 12 are rotated, and the water accumulated in the crushing chamber 7 and the discharge chamber 11 is agitated rapidly by centrifugal force, and each chamber is washed with a strong water pressure.
In this way, since stirring is performed when the amount of water in the crushing chamber 7 reaches a required amount, washing can be performed effectively, and even if the amount of water in the crushing chamber 7 is reduced by drainage, the remaining water continues. The water supplied in this way is pressed against the inner wall by centrifugal force, and cleaning can be continued.
If water is discharged from the crushing chamber 7 to the discharge port 13 during cleaning, the water surface W of the trap 16 is pushed down to a height H, air leaks, and there is no limit on the amount of drainage. Increasingly, a large amount of water is rapidly drained through the trap 16 by its weight. For this reason, the discharge chamber 11 becomes negative pressure, and the water in the crushing chamber 7 is jetted into the discharge chamber 11 to clean the gap between the rotary plate 8 and the fixed blade 10, and from the trap 16 to the previous discharge pipe. A large amount of drainage is generated and the clogging in the drain pipe is washed away.

攪拌洗浄は回転板８を３秒ないし８秒程度回転させればよく、排出室１１内の水が排出され負圧になると、破砕室７からの水とともに隙間Ｇから排出室１１に空気が入り込むため給水により空気を閉じ込めて再び水を溜めることができ、洗浄を繰り返し、あるいはすすぎ洗いをすることができる。
また、破砕室７に水を溜め、インペラの回転数を上げてポンプ作用により排出管に急激に流すことにより排出管内の詰まりを除くこともできる。
なお、厨芥の粉砕処理をした後に引き続いて洗浄する場合や、洗浄を繰り返えして行なう場合は、異物を検出するための低速での繰り返し運転を省略することができる。 For stirring and washing, the rotating plate 8 may be rotated for about 3 to 8 seconds. When the water in the discharge chamber 11 is discharged and becomes negative pressure, air enters the discharge chamber 11 through the gap G together with the water from the crushing chamber 7. Therefore, air can be confined by water supply and water can be stored again, and washing can be repeated or rinsed.
In addition, clogging in the discharge pipe can be eliminated by accumulating water in the crushing chamber 7, increasing the rotation speed of the impeller, and rapidly flowing it through the discharge pipe by a pump action.
In addition, when it wash | cleans continuously after grind | pulverizing a soot, or when performing washing | cleaning repeatedly, the low speed repeated operation for detecting a foreign material can be abbreviate | omitted.

次に図８に示す制御特性の例を説明する。
排出室１１にインペラ１２をそなえ、排出口１３が接線方向に設けられているディスポーザを用い、図７の実施例と同様に、回転板８とインペラ１２を停止させた状態で破砕室７に給水し、空気通路を塞いで空気を閉じ込め、破砕室７と排出室１１内に水を溜める。
時間ｔ２で破砕室７内の水がほぼ所定量になると、電動機１７で回転板８とインペラ１２を低速度ｎ３で逆回転させる。このため、回転板８で破砕室７内の水に遠心力を加えて破砕室内壁に押し付けながら回転洗浄させるとともに、排出室１１内の水にもインペラ１２で遠心力を与えて室内を洗浄し排水されるが、インペラ１２のポンプ作用が逆方向に働いているため、破砕室７から排出室１１に落ちる水の落下を遅らせて破砕室７内の水を保持させ、引き続いて供給される水とともに、回転板８で破砕室内の洗浄を継続させる。したがって逆方向の回転数ｎ３を、排水口１３から排水される水量と継続して破砕室へ給水される水量とが同程度になるようにしておけば、破砕室７内の洗浄水量を保持させることができ、洗浄時間を自由に調整できる。 Next, an example of the control characteristics shown in FIG. 8 will be described.
Water is supplied to the crushing chamber 7 in a state where the rotating plate 8 and the impeller 12 are stopped as in the embodiment of FIG. 7 using a disposer in which the impeller 12 is provided in the discharge chamber 11 and the discharge port 13 is provided in the tangential direction. Then, the air passage is closed to confine the air, and water is accumulated in the crushing chamber 7 and the discharge chamber 11.
When the water of the crushing chamber 7 is substantially a predetermined amount at time t 2, the rotary plate 8 and the impeller 12 is reversely rotated at a low speed n 3 by an electric motor 17. For this reason, the rotating plate 8 applies centrifugal force to the water in the crushing chamber 7 to rotate and wash it against the wall of the crushing chamber, and the water in the discharge chamber 11 is also centrifuged by the impeller 12 to wash the room. Although the water is drained, the pumping action of the impeller 12 works in the opposite direction, so that the water falling from the crushing chamber 7 to the discharge chamber 11 is delayed to hold the water in the crushing chamber 7, and subsequently supplied water. At the same time, the crushing chamber is continuously cleaned with the rotating plate 8. Therefore, if the rotational speed n 3 in the reverse direction is set so that the amount of water drained from the drain port 13 and the amount of water continuously supplied to the crushing chamber are approximately the same, the amount of washing water in the crushing chamber 7 is maintained. The cleaning time can be adjusted freely.

時間ｔ３で洗浄が終わると、回転板８とインペラ１２を停止させ、破砕室７と排出室１１内の洗浄水を排出させる。破砕室への給水を続けていても、洗浄水の排出で排出室１１が負圧になるので破砕室７から排出室１１へ落ちる水とともに回転板周囲のどこからか排出室１１に空気が入り込むので、負圧が解消され停止状態での給水が続くと前記と同様の作用で破砕室７に水が溜まってくる。インペラ１２を正回転させて破砕室７内に溜まった水を正常のポンプ作用で急速に排出させ、すすぎ洗いとともに排出管内に滞留している厨芥などを押し流して排出管の洗浄を行なわせることができる。 When cleaning is completed at time t 3 , the rotating plate 8 and the impeller 12 are stopped, and the cleaning water in the crushing chamber 7 and the discharge chamber 11 is discharged. Even if the water supply to the crushing chamber is continued, the discharge chamber 11 becomes negative pressure due to the discharge of the washing water, so air enters the discharge chamber 11 from somewhere around the rotating plate together with the water falling from the crushing chamber 7 to the discharge chamber 11. When the negative pressure is eliminated and the water supply in the stopped state continues, water accumulates in the crushing chamber 7 by the same action as described above. The impeller 12 is rotated forward so that the water accumulated in the crushing chamber 7 is quickly discharged by a normal pumping action, and the drain pipe is washed by rinsing the scum and the like remaining in the discharge pipe. it can.

なお、図９に示す特性曲線のように、洗浄が終わったときに、インペラ１２を低速度で正回転させ破砕室７と排出室１１内の汚れた洗浄水をポンプ作用で排出させ、回転板８を停止させて次の水溜めを行なわせるようにしてもよい。 As shown in the characteristic curve shown in FIG. 9, when the cleaning is completed, the impeller 12 is rotated forward at a low speed so that the dirty cleaning water in the crushing chamber 7 and the discharge chamber 11 is discharged by a pump action, and the rotating plate 8 may be stopped and the next sump may be performed.

図１０は、厨芥の粉砕処理に引き続いて洗浄を行なうようにした例を示す特性曲線で、図６と同様に、低速ｎ１の短時間運転を数回繰り返して異物の混入を検出し、異物の混入がないことを確認して低速ｎ１で一定時間連続運転した後、定格回転数ｎ２に昇速して粉砕処理を行なう。粉砕処理が終わると回転板８およびインペラ１２を低速ｎ３の逆回転に切り替える。インペラ１２が逆回転すると、逆方向のポンプ作用が働いて破砕室７から排出室１１に落ちる水の落下を遅らせて破砕室内に水が溜まり、回転板８で遠心力を加えて洗浄を行わせ、排出室１１も排出室内の水で洗浄する。
所定時間の洗浄を行なって回転板８とインペラ１２を停止させると、洗浄した汚水が排出され、引き続いて供給されている水が図８の実施例と同様に破砕室７に溜まり、インペラ１２を正回転させて急速に排出管に排出させて排出管の洗浄を行なわせる。 FIG. 10 is a characteristic curve showing an example in which washing is performed subsequent to the pulverization process of the soot. Similar to FIG. 6, a short time operation at a low speed n 1 is repeated several times to detect the inclusion of foreign matters. After confirming that there is no contamination, the vehicle is continuously operated at a low speed n 1 for a certain period of time, and then the speed is increased to the rated rotational speed n 2 to perform pulverization. And the grinding process is completed switch the rotating plate 8 and the impeller 12 in the reverse rotation of the low speed n 3. When the impeller 12 rotates in the reverse direction, the pumping action in the reverse direction works to delay the fall of the water falling from the crushing chamber 7 to the discharge chamber 11 and the water accumulates in the crushing chamber. The discharge chamber 11 is also washed with water in the discharge chamber.
When the rotating plate 8 and the impeller 12 are stopped after cleaning for a predetermined time, the cleaned sewage is discharged, and the water supplied subsequently is accumulated in the crushing chamber 7 as in the embodiment of FIG. Rotate forward to quickly discharge to the discharge pipe and clean the discharge pipe.

なお、本発明は破砕室への給水によって破砕室と排出室との空気通路を塞ぐようにしているので、ディスポーザの取り付けが傾いて回転板が傾斜していたり、破砕室の側面に給水口を設けて一方の側から他方側に向けて水を供給するディスポーザなどの場合は、空気通路の閉塞が部分的に遅れて閉じ込められる空気量が少なくなり、空気圧の減少で排出水量の制限が十分に行なわれず、水を溜めるための時間が長くなったり、水が溜まらなくなるおそれがある。このため、ディスポーザの取り付けを回転板が水平になるように修正したり、閉塞させるまでの供給水量を増すことも必要になる。 In the present invention, the air passage between the crushing chamber and the discharge chamber is closed by supplying water to the crushing chamber, so that the disposer is inclined and the rotating plate is inclined, or a water supply port is provided on the side of the crushing chamber. In the case of a disposer or the like that supplies water from one side to the other side, the amount of air trapped is partially delayed due to blockage of the air passage, and the amount of discharged water is sufficiently limited by reducing the air pressure. This is not done, and there is a possibility that the time for storing the water may become longer or the water may not be stored. For this reason, it is also necessary to correct the disposer attachment so that the rotating plate is horizontal or to increase the amount of water supplied until the disposer is closed.

図１１はディスポーザの破砕室側面から給水する場合の例を示すもので、図１と同じ部分に同一の符号を付している。
破砕室７への給水は電磁弁２６により給水管２７を介して破砕室７の側壁に設けた給水口２８から給水され、この給水口２８を従来のように単に側面から横方向に開口させるのではなく、回転板８の中央部に向けて開口させており、洗浄時に給水口２８から回転板８上に落ちた水が、回転板８の全面に広がって周囲の排出室１１との空気通路に均等に流れて一気に塞ぐようにしている。
なお、ディスポーザの側面から給水する場合は、給水口をできるだけ排水口３に近づけた高い位置に設けて中央部に向け、回転板上に落ちる水を拡散させるようにすることが望ましい。
また、シンク２に溢水口２９を設けている場合は、通常のようにオーバーフロー管３０をトラップより上部の排出管に接続すると、空気を閉じ込める時に排出室１１内の空気がオーバーフロー管３０を介して溢水口２９に洩れるため、オーバーフロー管３０を粉砕室７に接続し、あるいは図示のように異径継手３１を介して給水管２７に接続して溢水を破砕室７へ排出させている。 FIG. 11 shows an example in which water is supplied from the side surface of the crushing chamber of the disposer, and the same reference numerals are given to the same parts as in FIG.
Water supplied to the crushing chamber 7 is supplied from a water supply port 28 provided on the side wall of the crushing chamber 7 through a water supply pipe 27 by a solenoid valve 26, and the water supply port 28 is simply opened laterally from the side as in the prior art. Instead, it opens toward the center of the rotating plate 8, and water that has dropped onto the rotating plate 8 from the water supply port 28 during cleaning spreads over the entire surface of the rotating plate 8 and is an air passage with the surrounding discharge chamber 11. It flows evenly and closes at once.
In addition, when water is supplied from the side surface of the disposer, it is desirable to provide the water supply port at a high position as close as possible to the drainage port 3 so as to diffuse the water falling on the rotating plate toward the center.
Further, when the overflow port 29 is provided in the sink 2, if the overflow pipe 30 is connected to the discharge pipe above the trap as usual, the air in the discharge chamber 11 passes through the overflow pipe 30 when trapping the air. In order to leak into the overflow port 29, the overflow pipe 30 is connected to the crushing chamber 7, or is connected to the water supply pipe 27 via a different diameter joint 31 as shown in the figure, and the overflow water is discharged to the crushing chamber 7.

図１２は、ディスポーザの別の実施例を示しており、破砕室７内の上部周囲に環状の給水管３２を設け、側壁に向けて多数の給水孔３３をそなえている。この実施例では給水孔３３からの水が矢示のように破砕室７の内壁に向けて給水され、内壁を伝って固定刃１０と回転板８の周囲との間隙Ｇに一様に給水されるので、空気通路の閉塞を有効に行なうことができる。 FIG. 12 shows another embodiment of the disposer, in which an annular water supply pipe 32 is provided around the upper part in the crushing chamber 7, and a large number of water supply holes 33 are provided toward the side wall. In this embodiment, the water from the water supply hole 33 is supplied toward the inner wall of the crushing chamber 7 as indicated by the arrow, and is uniformly supplied to the gap G between the fixed blade 10 and the periphery of the rotating plate 8 along the inner wall. Therefore, the air passage can be effectively blocked.

また、図１３は回転板８の別の実施例である。洗浄をするときは回転板８上に供給される水をなるべく全周の間隙Ｇに同時に流し込み、間隙Ｇを一気に塞ぐようにするため回転板８の中央に給水することが望ましい。このため、上面に固定された打撃刃９をそなえた回転板８の外周に縁３４を設けて均等に高くしている。このような縁３４を設けることによって、回転板８の片方たとえば左側に偏って給水され、右側の空気通路の閉塞が遅れる恐れがある場合であっても、縁３４があるために、偏って落下した水が回転板８上の全面に溜まり、縁３４を越えた水が周囲の空気通路に同時に溢れ出すので全周の空気通路を一気に塞ぎ、閉塞を有効に行なうことができる。
なお、縁３４に替えて図１４に示すように、回転板８の上面を外周が高くなるよう皿状に傾斜させてもよい。 FIG. 13 shows another embodiment of the rotating plate 8. When cleaning is performed, it is desirable that water supplied onto the rotating plate 8 is poured into the gap G around the entire circumference as much as possible, and water is supplied to the center of the rotating plate 8 in order to close the gap G at a stretch. For this reason, the edge 34 is provided in the outer periphery of the rotating plate 8 which provided the striking blade 9 fixed to the upper surface, and is made equally high. By providing such an edge 34, even if there is a possibility that water is supplied to one side of the rotating plate 8, for example, to the left side, and the blockage of the right air passage may be delayed, the rim 34 is provided and the water drops. The accumulated water accumulates on the entire surface of the rotating plate 8, and the water beyond the edge 34 overflows into the surrounding air passages at the same time. Therefore, the air passages around the entire circumference can be closed at once, and the blockage can be effectively performed.
Instead of the edge 34, as shown in FIG. 14, the upper surface of the rotating plate 8 may be inclined in a dish shape so that the outer periphery becomes higher.

また、シンク２の排水口３にめくら蓋をして水を溜め、給水しながらめくら蓋を取り外して破砕室７に流し込むことにより、破砕室７と排出室１１との空気通路を塞ぐようにすることもできる。 Further, a blind cover is put on the drain port 3 of the sink 2 to collect water, and the blind cover is removed while pouring water and poured into the crushing chamber 7 to block the air passage between the crushing chamber 7 and the discharge chamber 11. You can also.
