Description

【０００１】
【発明の属する技術分野】
本発明は、調理時に発生する煙り、湯気、臭気等を捕集して外部に排出するレンジフードにおけるフィルターを清掃する装置に関する。
【０００２】
【従来の技術】
レンジフードとしては、例えば特公平１−５４６１８号公報に示すように、送風機と吸気口とを連通する吸気風路に複数の邪魔板を取付け、この吸気風路を流れる油煙が邪魔板によって強制的に屈曲させられることで油煙中の油脂粒子が邪魔板や風路内壁に付着して油脂分を分離除去する。前記邪魔板や風路内壁に洗浄ノズルで洗浄液を噴射して付着した油脂分を洗い落すものが知られている。
【０００３】
このレンジフードであれば、邪魔板や風路内壁に付着した油脂分を洗浄液で洗い落として清掃できるので、人手によって邪魔板や風路内壁を清掃する必要がない。
【０００４】
【発明が解決しようとする課題】
レンジフードとしては、フード体の内部にフィルターを取付け、そのフード体内部にフィルターを境として吸込部と排出部を形成し、その排出部に送風機を取付けたものが知られている。
【０００５】
このレンジフードであれば、送風機を駆動することで空気を吸込部より吸込み、その吸込んだ空気をフィルターを通して排出部に吸込み、排気ダクトなどを通して外部に排出することができる。
また、吸込んだ空気中の油分や水蒸気をフィルターで捕集でき、排出ダクトを流れる空気中の油分や水蒸気の量が著しく減少するので、排出ダクト内で油分や水蒸気が結露して排出ダクトより流れ出ることがない。
【０００６】
前述のレンジフードはフィルターによってフード体内部を吸込部と排出部に区画しているから、そのフィルターは大面積である。このために、従来のレンジフードのように洗浄ノズルによって洗浄液をフィルターに噴射すると、洗浄液がフィルター全面に均一に噴射されないから、洗浄液をフィルター全面に均一に流下させることができずにフィルターを均一に清掃できない。
【０００７】
そこで、本発明は前述の課題を解決できるようにしたレンジフードのフィルター清掃装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
第１の発明は、フード体１内を縦向きのフィルター１１で吸込部１２と排出部１３に区画し、送風機１６で排出部１３内の空気を吸引して排出することで吸込部１２の空気がフィルター１１を通って排出部１３に吸込まれるようにしたレンジフードにおいて、
前記フィルター１１よりも上部寄りに、洗浄液樋２４を、当該フィルター１１の長手方向全長に亘って取付け、この洗浄液樋２４に洗浄液を供給するように構成し、
前記洗浄液樋２４は、その底板３０に洗浄液供給孔３２がフィルター１１の長手方向に沿って間隔を置いて複数形成されていると共に、この各洗浄液供給孔３２の開口縁と連続して筒状の水切り部３３が下向きに一体的にそれぞれ設けてあり、この各水切り部３３から洗浄液がフィルター１１の上縁部に落下供給されるように構成したことを特徴とするレンジフードのフィルター清掃装置。
【０００９】
第２の発明は、第１の発明における洗浄液樋２４の底部に流体流通の抵抗となる流体流通抵抗体３４を、この洗浄液樋２４に供給された洗浄液が当該流体流通抵抗体３４を流通して洗浄液供給孔３２から落下するように設けたレンジフードのフィルター清掃装置である。
【００１０】
第３の発明は、第１の発明又は第２の発明におけるフィルター１１の下縁部に洗浄液受皿２０を設け、この洗浄液受皿２０の下方に洗浄液槽２２を設けてフィルター１１に沿って流れた洗浄液が洗浄液槽２２内に溜るようにし、
前記洗浄液槽２２内の洗浄液を洗浄液供給ポンプ２７によって前記洗浄液樋２４に供給するようにしたレンジフードのフィルター清掃装置である。
【００１１】
【作用】
第１の発明によれば、洗浄液樋２４内の洗浄液は洗浄液供給孔３２から落下し、その開口縁に設けた筒状の水切り部３３によって水切りされるので、流れが安定すると共に、流れがガイドされて各洗浄液供給孔３２より落下した洗浄液はフィルター１１の上縁部に向けてそれぞれ一条の流れとして正しく落下供給される。
【００１２】
これによって、洗浄液はフィルター１１上縁部に均一に落下供給され、フィルター１１全面に均一に安定して流下するので、フィルター１１の全面を均一に清掃することができる。
【００１３】
第２の発明によれば、洗浄液樋２４内に供給された洗浄液は流体流通抵抗体３４を通って洗浄液供給孔３２に流れるので、例えば１本の洗浄液供給パイプにより洗浄液樋２４の長手方向一個所に集中的に供給された洗浄液の乱れた圧力が流体流通抵抗体３４によって均一な圧力となり、各洗浄液供給孔３２には安定した洗浄液圧が加えられて均一に落下供給する。
【００１４】
これによって、例えば１本の洗浄液供給パイプで洗浄液樋２４に洗浄液を供給する場合でも洗浄液はフィルター１１の上縁部に均一に落下供給され、フィルター１１全面に均一に安定して流下するので、フィルター１１の全面を均一に清掃することができる。
【００１５】
第３の発明によれば、フィルター１１に沿って流れ落ちた洗浄液は再び洗浄液樋２４に供給されるので、洗浄液を循環して再利用できる。
【００１６】
【発明の実施の形態】
図１に示すように、フード体１は後側フード体２と、前側フード体３を有する。後側フード体２は後面板４と相対向した一対の側面板５と天板６により下部と前部が開口した箱状となっている。前記前側フード体３は前面板７と、相対向した一対の側面板８と天板９により下部と後部が開口した箱状と成っている。
【００１７】
前記後側フード体２と前側フード体３を連結してフード体１としてある。このフード体１は下部が開口した箱状となっている。
【００１８】
前記後側フード体２の一対の側面板５の下部寄り間に仕切板１０が取付けてある。この仕切板１０と天板６とに亘ってフィルター１１が縦向きに取付けてある。フード体１内はフィルター１１を境として下部に開口した吸込部１２と排出部１３に区画してある。
【００１９】
前記排出部１３内には電動モータ１４により回転されるファン１５を備えた送風機１６が設けてあり、この送風機１６の吸込部が排出部１３に開口し、吐出側に排気ダクトが接続してある。
【００２０】
このようであるから、電動モータ１４によりファン１５を回転すると吸込部１２より空気が吸込まれる。その吸込まれた空気はフィルター１１を通して排出部１３に流れ込む。排出部１３に流れ込んだ空気は送風機１６の吐出側から排出ダクトに排出される。
【００２１】
前記仕切板１０の上面に洗浄液受皿２０が取付けてある。この洗浄液受皿２０にフィルター１１の下部がブラケット２１で取付けてある。前記仕切板１０の下面に洗浄液槽２２が取付けてある。これによってフィルター１１に沿って流れ落ちた洗浄液は洗浄液受皿２０内に落下し、排出口２３から洗浄液槽２２内に流れ込む。
【００２２】
前記後側フード体２の天板６には洗浄液樋２４が取付けてある。この洗浄液樋２４にブラケット２５を介してフィルター１１の上部が取付けてある。前記洗浄液槽２２内の洗浄液は電動モータ２６で駆動される洗浄液供給ポンプ２７で洗浄液供給パイプ２８に吐出され、その洗浄液供給パイプ２８によって洗浄液樋２４に供給される。
【００２３】
前記フィルター１１は図２，図３に示すように相対向した一対の側面板５間に亘って取付けてある。洗浄液樋２４は底板３０と周壁板３１とで上部が開口したほぼ平面長方形状である。この洗浄液樋２４はフィルター１１よりも上部寄りに長手方向全長に亘って取付けてあり、その周壁板３１の後部３１ａにおける長手方向中央部に前記洗浄液供給パイプ２８が取付けてある。前記洗浄液樋２４は上板を有する密閉された箱状としても良い。
【００２４】
前記底板３０は前部寄り３０ａが後部寄り３０ｂよりも下方となるようにほぼ階段形状に折り曲げてあり、洗浄液樋２４は前部寄り部分が深く、後部寄り部分が浅くなっている。
【００２５】
前記底板３０の前部寄りには複数の洗浄液供給孔３２が長手方向に間隔を置いて形成してある。この洗浄液供給孔３２の開口縁と連続して筒状の水切り部３３が下向きに一体的に設けてある。例えば、洗浄液樋２４を金属製とし、その底板３０の前部寄り３０ａをバーリング加工して水切り部３３を有する洗浄液供給孔３２としてある。
【００２６】
なお、洗浄液樋２４を樹脂による射出成形品としても良い。
【００２７】
このようであるから、洗浄液樋２４内に供給された洗浄液は図３に示すように前部寄り部分に溜り、各洗浄液供給孔３２からフィルター１１の上縁部に落下供給される。この時に、洗浄液供給孔３２の開口縁と連続して下向きに一体的に設けた筒状の水切り部３３によって洗浄液が底板３０の下面から水切りされると共に、真下に向けて流れるようにガイドされるので、各洗浄液供給孔３２から洗浄液ａが図３に示すようにフィルター１１の上縁部に向けてそれぞれ一条の流れとして正しく落下供給される。
【００２８】
したがって、洗浄液はフィルター１１上縁部に均一に落下供給され、フィルター１１全面に均一に安定して洗浄液が流下するので、フィルター１１の全面を均一に清掃することができる。
【００２９】
図４は本発明の第２の実施の形態を示し、洗浄液樋２４の前部寄り部分にスポンジ、複数の金網を重ねたものなどの流体流通の抵抗となる流体流通抵抗体３４を設けてある。
【００３０】
このようにすれば、洗浄液供給パイプ２８から洗浄液槽２４内に吐出された洗浄液は流体流通抵抗体３４を流れて洗浄液供給孔３２から落下するので、その吐出された洗浄液の乱れた圧力が直接洗浄液供給孔３２に加わらず、それぞれの洗浄液供給孔３２には安定した洗浄液圧が加えられ均一に落下供給する。
【００３１】
また、流体流通抵抗体３４を設けただけであるから、洗浄液樋を小型化することが可能であり、レンジフード高さ寸法、奥行きなどの制限受ける恐れが少なく、さらに簡単で安価に製作することができる。
【００３２】
具体的には、レンジフード下部の洗浄液槽２２から洗浄液供給ポンプ２７により洗浄液供給パイプ２８を通して洗浄液樋２４へ洗浄液が送られるが、その際、洗浄液供給パイプ２８から洗浄液樋２４へ吐出された洗浄液を直接洗浄液供給孔３２に向けて吐出すると、吐出個所近傍にある洗浄液供給孔３２からの流出が激しくなり、吐出個所から離れるに従い流出が弱くなる。この状態ではフィルター１１上部に均一に落下供給できない。この状態を回避し、どの洗浄液供給孔からも均一に落下供給するできる状態にするためには、洗浄液供給パイプから吐出された洗浄液の勢いを直接洗浄液供給孔に届かせないよう洗浄液供給孔からの距離をとり、そこに圧力分散板等を配置するか、もしくは洗浄液樋の深さを深くし、洗浄液供給孔径を小さくしたり、または各洗浄液供給孔からの流量をそれぞれ調節する方法などが考えられるが、レンジフード高さ寸法、奥行きなどの制限より、前記対策は非常に困難ある。
【００３３】
【発明の効果】
第１の発明によれば、洗浄液樋２４内の洗浄液は洗浄液供給孔３２から落下し、その開口縁に設けた筒状の水切り部３３によって水切りされるので、流れが安定すると共に、流れがガイドされて各洗浄液供給孔３２より落下した洗浄液はフィルター１１の上縁部に向けてそれぞれ一条の流れとして正しく落下供給される。
【００３４】
これによって、洗浄液はフィルター１１上縁部に均一に落下供給され、フィルター１１全面に均一に安定して流下するので、フィルター１１の全面を均一に清掃することができる。
【００３５】
第２の発明によれば、洗浄液樋２４内に供給された洗浄液は流体流通抵抗体３４を通って洗浄液供給孔３２に流れるので、例えば１本の洗浄液供給パイプにより洗浄液樋２４の長手方向一個所に集中的に供給された洗浄液の乱れた圧力が流体流通抵抗体３４によって均一な圧力となり、各洗浄液供給孔３２には安定した洗浄液圧が加えられて均一に落下供給する。
【００３６】
これによって、例えば、１本の洗浄液供給パイプで洗浄液樋２４に洗浄液を供給する場合でも洗浄液はフィルター１１の上縁部に均一に落下供給され、フィルター１１全面に均一に安定して流下するので、フィルター１１の全面を均一に清掃することができる。
【００３７】
第３の発明によれば、フィルター１１に沿って流れ落ちた洗浄液は再び洗浄液樋２４に供給されるので、洗浄液を循環して再利用できる。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for cleaning a filter in a range hood that collects smoke, steam, odor, and the like generated during cooking and discharges them outside.
[0002]
[Prior art]
As a range hood, for example, as shown in Japanese Patent Publication No. 1-54618, a plurality of baffle plates are attached to an intake air passage communicating with a blower and an intake port, and oil smoke flowing through the intake air passage is forced by the baffle plate. The oil and fat particles in the oily smoke adhere to the baffle plate and the inner wall of the air passage to separate and remove the oil and fat. It is known to wash away oil and fat adhering to the baffle plate and the inner wall of the air passage by spraying a cleaning liquid with a cleaning nozzle.
[0003]
With this range hood, the oil and fat adhering to the baffle plate and the air passage inner wall can be cleaned by washing with the cleaning liquid, so that it is not necessary to manually clean the baffle plate and the air passage inner wall.
[0004]
[Problems to be solved by the invention]
A range hood is known in which a filter is attached inside the hood body, a suction portion and a discharge portion are formed inside the hood body with the filter as a boundary, and a blower is attached to the discharge portion.
[0005]
If it is this range hood, air can be sucked in from a suction part by driving a blower, the sucked air can be sucked into a discharge part through a filter, and can be discharged outside through an exhaust duct etc.
In addition, the oil and water vapor in the sucked air can be collected by a filter, and the amount of oil and water vapor in the air flowing through the discharge duct is remarkably reduced, so oil and water vapor condenses in the discharge duct and flows out of the discharge duct. There is nothing.
[0006]
Since the above-described range hood partitions the inside of the hood body into a suction part and a discharge part by a filter, the filter has a large area. For this reason, when the cleaning liquid is sprayed onto the filter by the cleaning nozzle as in a conventional range hood, the cleaning liquid is not sprayed uniformly on the entire surface of the filter. I can't clean it.
[0007]
Then, an object of this invention is to provide the filter cleaning apparatus of the range hood which enabled it to solve the above-mentioned subject.
[0008]
[Means for Solving the Problems]
1st invention divides the inside of the food | hood body 1 into the suction part 12 and the discharge part 13 with the vertical filter 11, and sucks and discharges the air in the discharge part 13 with the air blower 16, and is the air of the suction part 12 In the range hood that is sucked into the discharge part 13 through the filter 11,
A cleaning liquid bowl 24 is attached to the upper side of the filter 11 over the entire length in the longitudinal direction of the filter 11, and the cleaning liquid is supplied to the cleaning liquid bowl 24.
A plurality of cleaning liquid supply holes 32 are formed in the bottom plate 30 at intervals along the longitudinal direction of the filter 11, and the cleaning liquid tank 24 has a cylindrical shape continuously with the opening edge of each cleaning liquid supply hole 32. A range hood filter cleaning device, wherein drainage portions 33 are integrally provided downward, and the cleaning liquid is dropped and supplied from each drainage portion 33 to the upper edge portion of the filter 11 .
[0009]
In the second aspect of the invention, a fluid circulation resistor 34 that provides resistance to fluid flow is provided at the bottom of the cleaning liquid tank 24 in the first invention, and the cleaning liquid supplied to the cleaning liquid tank 24 flows through the fluid circulation resistor 34. It is a filter cleaning device for a range hood provided so as to drop from the cleaning liquid supply hole 32 .
[0010]
In the third aspect of the invention, the cleaning liquid tray 20 is provided at the lower edge of the filter 11 in the first or second aspect, and the cleaning liquid tank 22 is provided below the cleaning liquid tray 20 so that the cleaning liquid flows along the filter 11. In the cleaning liquid tank 22,
It is a filter cleaning device for a range hood in which the cleaning liquid in the cleaning liquid tank 22 is supplied to the cleaning liquid tank 24 by a cleaning liquid supply pump 27.
[0011]
[Action]
According to the first invention, the cleaning liquid of the cleaning liquid trough 24 will fall from the cleaning liquid supply hole 32, Runode is drained by tubular draining portion 33 provided on the opening edge, with the flow is stabilized, the flow guide Then, the cleaning liquid dropped from each cleaning liquid supply hole 32 is correctly dropped and supplied as a single stream toward the upper edge of the filter 11.
[0012]
As a result, the cleaning liquid is dropped and supplied uniformly to the upper edge of the filter 11 and flows uniformly and stably over the entire surface of the filter 11, so that the entire surface of the filter 11 can be cleaned uniformly.
[0013]
According to the second invention, the cleaning liquid supplied into the cleaning liquid tank 24 flows into the cleaning liquid supply hole 32 through the fluid flow resistor 34, and therefore, for example, one cleaning liquid supply pipe is provided at one location in the longitudinal direction of the cleaning liquid tank 24. The turbulent pressure of the cleaning liquid supplied intensively is made uniform by the fluid flow resistor 34, and a stable cleaning liquid pressure is applied to each cleaning liquid supply hole 32 so as to drop it uniformly.
[0014]
Thus, for example, even when the cleaning liquid is supplied to the cleaning liquid tank 24 with a single cleaning liquid supply pipe, the cleaning liquid is evenly supplied to the upper edge of the filter 11 and flows uniformly and stably over the entire surface of the filter 11. The entire surface of 11 can be cleaned uniformly.
[0015]
According to the third aspect, since the cleaning liquid that has flowed down along the filter 11 is supplied again to the cleaning liquid tank 24, the cleaning liquid can be circulated and reused.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the hood body 1 includes a rear hood body 2 and a front hood body 3. The rear hood body 2 has a box shape in which a lower portion and a front portion are opened by a pair of side plates 5 and a top plate 6 facing the rear plate 4. The front hood body 3 has a box shape in which a lower portion and a rear portion are opened by a front plate 7, a pair of side plates 8 and a top plate 9 facing each other.
[0017]
The rear hood body 2 and the front hood body 3 are connected to form a hood body 1. The hood body 1 has a box shape with an open bottom.
[0018]
A partition plate 10 is attached between the lower portions of the pair of side plates 5 of the rear hood body 2. A filter 11 is attached vertically across the partition plate 10 and the top plate 6. The inside of the hood body 1 is partitioned into a suction part 12 and a discharge part 13 that open to the lower part with a filter 11 as a boundary.
[0019]
A blower 16 having a fan 15 that is rotated by an electric motor 14 is provided in the discharge portion 13, a suction portion of the blower 16 opens to the discharge portion 13, and an exhaust duct is connected to the discharge side. .
[0020]
Thus, when the fan 15 is rotated by the electric motor 14, air is sucked from the suction portion 12. The sucked air flows into the discharge unit 13 through the filter 11. The air flowing into the discharge unit 13 is discharged from the discharge side of the blower 16 to the discharge duct.
[0021]
A cleaning liquid tray 20 is attached to the upper surface of the partition plate 10. The lower part of the filter 11 is attached to the cleaning liquid tray 20 with a bracket 21. A cleaning liquid tank 22 is attached to the lower surface of the partition plate 10. As a result, the cleaning liquid that has flowed down along the filter 11 falls into the cleaning liquid tray 20 and flows into the cleaning liquid tank 22 from the discharge port 23.
[0022]
A cleaning liquid bowl 24 is attached to the top plate 6 of the rear hood body 2. The upper part of the filter 11 is attached to the cleaning liquid tank 24 via a bracket 25. The cleaning liquid in the cleaning liquid tank 22 is discharged to a cleaning liquid supply pipe 28 by a cleaning liquid supply pump 27 driven by an electric motor 26 and supplied to the cleaning liquid tank 24 by the cleaning liquid supply pipe 28.
[0023]
As shown in FIGS. 2 and 3, the filter 11 is mounted between a pair of side plates 5 facing each other. The cleaning liquid tank 24 has a substantially flat rectangular shape with an upper portion opened by the bottom plate 30 and the peripheral wall plate 31. The cleaning liquid tank 24 is attached to the upper part of the filter 11 over the entire length in the longitudinal direction, and the cleaning liquid supply pipe 28 is attached to the central part in the longitudinal direction of the rear portion 31a of the peripheral wall plate 31. The cleaning liquid bowl 24 may be a sealed box shape having an upper plate.
[0024]
The bottom plate 30 is bent in a substantially step shape so that the front side 30a is lower than the rear side 30b, and the cleaning liquid tank 24 is deeper at the front side and shallower at the rear side.
[0025]
Near the front portion of the bottom plate 30, a plurality of cleaning liquid supply holes 32 are formed at intervals in the longitudinal direction. A cylindrical draining portion 33 is integrally provided downward and continuous with the opening edge of the cleaning liquid supply hole 32. For example, the cleaning liquid tank 24 is made of metal, and the front side 30 a of the bottom plate 30 is subjected to burring to form a cleaning liquid supply hole 32 having a draining portion 33.
[0026]
The cleaning liquid tank 24 may be an injection molded product made of resin.
[0027]
As described above, the cleaning liquid supplied into the cleaning liquid tank 24 accumulates at the front portion as shown in FIG. 3, and is dropped and supplied from the cleaning liquid supply holes 32 to the upper edge of the filter 11. At this time, the cleaning liquid is drained from the lower surface of the bottom plate 30 by the cylindrical draining portion 33 integrally provided downward and continuously with the opening edge of the cleaning liquid supply hole 32, and is guided so as to flow downward. Therefore, the cleaning liquid a is correctly supplied as a single stream from each cleaning liquid supply hole 32 toward the upper edge of the filter 11 as shown in FIG.
[0028]
Accordingly, the cleaning liquid is uniformly supplied to the upper edge portion of the filter 11 and the cleaning liquid flows uniformly and stably on the entire surface of the filter 11, so that the entire surface of the filter 11 can be cleaned uniformly.
[0029]
FIG. 4 shows a second embodiment of the present invention, in which a fluid flow resistor 34 that provides resistance to fluid flow, such as a sponge or a plurality of metal meshes, is provided near the front portion of the cleaning liquid tub 24. .
[0030]
In this way, the cleaning liquid discharged from the cleaning liquid supply pipe 28 into the cleaning liquid tank 24 flows through the fluid flow resistor 34 and falls from the cleaning liquid supply hole 32, so that the turbulent pressure of the discharged cleaning liquid is directly applied to the cleaning liquid. A stable cleaning liquid pressure is applied to each cleaning liquid supply hole 32 without being applied to the supply holes 32, and the liquid is uniformly dropped and supplied.
[0031]
In addition, since only the fluid flow resistor 34 is provided, it is possible to reduce the size of the cleaning liquid tank, and there is little risk of receiving restrictions such as the height dimension and depth of the range hood. Can do.
[0032]
Specifically, the cleaning liquid is sent from the cleaning liquid tank 22 below the range hood to the cleaning liquid tank 24 through the cleaning liquid supply pipe 28 by the cleaning liquid supply pump 27. At this time, the cleaning liquid discharged from the cleaning liquid supply pipe 28 to the cleaning liquid tank 24 is discharged. When the liquid is directly discharged toward the cleaning liquid supply hole 32, the outflow from the cleaning liquid supply hole 32 in the vicinity of the discharge location becomes intense, and the outflow becomes weak as the distance from the discharge location increases. In this state, the filter 11 cannot be uniformly dropped and supplied. In order to avoid this state and to be able to drop and supply uniformly from any cleaning liquid supply hole, the momentum of the cleaning liquid discharged from the cleaning liquid supply pipe should not be directly delivered to the cleaning liquid supply hole. Possible methods include taking a distance, placing a pressure dispersion plate, etc., or increasing the depth of the cleaning liquid so that the cleaning liquid supply hole diameter is reduced, or adjusting the flow rate from each cleaning liquid supply hole. However, the above measures are very difficult due to limitations such as range hood height and depth.
[0033]
【The invention's effect】
According to the first invention, the cleaning liquid of the cleaning liquid trough 24 will fall from the cleaning liquid supply hole 32, Runode is drained by tubular draining portion 33 provided on the opening edge, with the flow is stabilized, the flow guide Then, the cleaning liquid dropped from each cleaning liquid supply hole 32 is correctly dropped and supplied as a single stream toward the upper edge of the filter 11.
[0034]
As a result, the cleaning liquid is dropped and supplied uniformly to the upper edge of the filter 11 and flows uniformly and stably over the entire surface of the filter 11, so that the entire surface of the filter 11 can be cleaned uniformly.
[0035]
According to the second invention, the cleaning liquid supplied into the cleaning liquid tank 24 flows into the cleaning liquid supply hole 32 through the fluid flow resistor 34, and therefore, for example, one cleaning liquid supply pipe is provided at one location in the longitudinal direction of the cleaning liquid tank 24. The turbulent pressure of the cleaning liquid supplied intensively is made uniform by the fluid flow resistor 34, and a stable cleaning liquid pressure is applied to each cleaning liquid supply hole 32 so as to drop it uniformly.
[0036]
Thereby, for example, even when the cleaning liquid is supplied to the cleaning liquid tank 24 with a single cleaning liquid supply pipe, the cleaning liquid is evenly supplied to the upper edge of the filter 11 and flows uniformly and stably over the entire surface of the filter 11. The entire surface of the filter 11 can be cleaned uniformly.
[0037]
According to the third aspect, since the cleaning liquid that has flowed down along the filter 11 is supplied again to the cleaning liquid tank 24, the cleaning liquid can be circulated and reused.
