Abstract

<P>PROBLEM TO BE SOLVED: To provide a relatively small washing device with a simple structure. <P>SOLUTION: A substrate 4 is provided with a suction tube 6 as a suction inlet on the side of the substrate 4 and a skirt part 5 on an edge 4a. The substrate 4 is further provided with a means for supplying a wash fluid 17 having an air inlet 7 and a nozzle 13 provided at the inlet 7. When the suction tube 6 is connected to such a suction means 1 to activate the suction means 1, the skirt part 5 is brought into contact with a portion to be washed A so as to form a region S between the substrate 4 and the portion to be washed A, whereby a venturi effect is produced in the region S by rapid air stream F coming from the inlet 7. Thus, wash fluid D is extruded from the nozzle 13 without using a pump and the like, and a wash fluid D is sprayed on the portion to be washed A, and then the wash fluid D containing dirt is sucked from the suction tube 6 into the suction means 1. In this manner, since the washing device has no power sources such as a pump for supplying the wash fluid D, the device can have relatively a simple and small structure. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明が属する技術分野】
本発明は、洗浄液を被洗浄箇所に供給すると共に、汚れた洗浄液を吸引源によって吸引する洗浄装置に関するものである。
【0002】
【発明が解決しようとする課題】
従来この種の洗浄装置としては、例えば以下のものが知られている。
【0003】
【特許文献1】
特開平10−34095号公報
【0004】
これは、内側に一定の空間を有する椀状の基体の縁部にブラシ体(スカート部)を形成し、前記基体に、吸引手段に接続される吸引ポート(吸引口)と、外部の給水手段に接続される噴射ノズル(ノズル)を形成し、給水手段によって水を噴射ノズルから被洗浄体(被洗浄箇所)に噴射させると共に、汚れた水を吸引ポートから吸引手段に吸い込むものである。なお、給水手段としては、ポンプ装置が用いられる。また、吸引手段の排気を利用して加圧された水を噴射ノズルから噴射させるものも知られている。
【0005】
しかしながら、このような洗浄装置においては、給水系統にポンプ装置等が必要になったり、また、吸引手段の排気を給水系統に接続する必要があったりするため、大型化するばかりでなく、構造が複雑になるという問題があった。
【0006】
本発明は以上の問題点を解決し、単純な構造で且つ比較的小型の洗浄装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明の請求項1に記載の洗浄装置は、被洗浄箇所を覆う基体と、この基体の縁に設けられて前記被洗浄箇所に接触するスカート部と、前記基体に設けられると共に吸引手段に接続される吸引口と、前記基体と被洗浄箇所で囲まれた領域に洗浄液を供給する洗浄液供給手段とを有する洗浄装置において、前記洗浄液供給手段が、前記基体に設けられた吸気口と、この吸気口に設けられたノズルとを有するものである。
【0008】
本発明は以上のように構成することにより、前記スカート部を被洗浄箇所に当接させて前記吸引手段を動作させると、前記吸気口から基体と被洗浄箇所によって囲まれた空間を経て前記吸引口から吸引手段に至る速い気流が発生することで、この気流によって前記吸気口においてベンチュリ効果が生じ、このベンチュリ効果による負圧によって前記ノズルから洗浄液が噴出し、この噴出した洗浄液が被洗浄箇所に吹き付けられると共に、汚れた洗浄液が前記気流と一緒に前記吸引口から排出される。
【0009】
また、本発明の請求項2に記載の洗浄装置は、請求項1において、前記吸気口に、気流の方向に対して徐々に狭くなる吸気入口部と、この吸気入口部の下流側に隣接して流通面積が最も狭くなる絞り部を設けたものである。
【0010】
本発明は以上のように構成することにより、前記吸引手段を動作させることによって発生した気流が前記吸気口の吸気入口部から絞り部にスムーズに流れる。
【0011】
【発明の実施形態】
以下、本発明の実施形態について、図1乃至図3に基づいて説明する。1は吸引手段である。なお、この吸引手段1は公知の気液分離可能な掃除機であるので、その構造の詳細な説明を省略する。そして、前記吸引手段1の吸引ホース2の先端には、洗浄具3が着脱自在に取り付けられている。この洗浄具3を構成する基体4は略器状に形成されていると共に、この基体4の縁4aには、合成ゴム等で形成されたスカート部5が固定されている。なお、このスカート部5は、その縁5aが同一平面上にあるように形成されている。また、前記基体4の側部には、前記吸引手段1の吸引ホース2に接続するための吸引口たる吸引管6が一体に形成されている。更に、前記基体4の略中央には、吸気口7が形成されている。この吸気口7は、気流Fの方向に対して徐々に狭くなるように形成された吸気入口部8と、流通面積が最も狭くなる絞り部9と、気流Fの方向に対して徐々に広くなるように形成された吸気出口部10とで形成されている。そして、前記基体4の内側には、前記吸気口7の周囲を囲むように、短筒状の壁部11が形成されている。なお、前記壁部11の先端11aには、その一部11bを除いてブラシ部12が形成されており、前記洗浄具3のスカート部5を平面状の被洗浄箇所Aに当接させた際に、前記先端11aが前記被洗浄箇所Aに近接すると共に、前記ブラシ部12が前記被洗浄箇所Aに接するように形成されている。更に、前記吸気口7の絞り部9には、ノズル13が設けられている。そして、このノズル13は、前記基体4から突出した接続管14と連通している。更に、この接続管14は、洗浄液供給管15を介して洗浄液容器16に接続されている。そして、前記ノズル13、接続管14、洗浄液供給管15及び洗浄液容器16によって、洗浄液供給手段17が構成されている。
【0012】
次に、本実施形態の作用について説明する。まず使用者は、前記洗浄具3の吸引管6を前記吸引手段1の吸引ホース2に接続する。また、前記洗浄液容器16に洗浄液Dを入れると共に、前記洗浄液供給管15を接続管14に接続する。なお、前記洗浄液Dとして、水等の溶媒や希釈された洗剤等が用いられる。そして、前記洗浄具3を把持して前記吸引手段1を動作させると、前記基体4の縁4aによって囲まれた開口部の外部から、この開口部、前記吸引管6、吸引ホース2を経て前記吸引手段1に流れる気流Fが発生する。このとき、前記基体4の開口部近傍から空気が吸引されると共に、吸引された空気を補うように、前記開口部近傍の周辺から空気が流れ込むことになるが、この空気は、その大半が、広く開放された前記基体4の開口部の正面側(図2における左側)から流れ込み、開口面積の小さい前記吸気口7を経て前記基体4の開口部の近傍へ流れ込む量が殆ど無い。即ち、この状態では、単純に前記基体4の開口部から吸引管6,吸引ホースを経て吸引手段1に気流Fが流れるだけである。
【0013】
そして使用者が、スカート部5の縁5a全体が平坦な被洗浄箇所Aと当接するように、前記洗浄具3を被洗浄箇所Aに押し当てると、この被洗浄箇所Aと前記基体4とスカート部5によって囲まれた領域Sは、前記吸気口7のみによって外部と連通する状態となる。このとき、前記スカート部5の縁5a全体と前記被洗浄箇所Aが接していることから、前記基体4外の空気は、前記基体4の開口部から領域S内に吸引されることができず、唯一、前記吸気口7から領域S内に吸引されて気流Fとなり、前記壁部11と被洗浄箇所Aとの隙間を経て、前記吸引管6に流れることになる。なお、前記気流Fが前記吸気口7の吸気入口部8を経て絞り部9を通過する際、ベンチュリ効果によって流速が増加すると共に負圧が発生する。そして、前記絞り部9において負圧が発生することによって、前記洗浄液Dは前記ノズル13から吸引されると共に、速い気流Fによって霧化する。そして、この霧化した洗浄液Dは、気流Fに乗って、前記被洗浄箇所Aに対して比較的均等に吹き付けられる。なお、前記吸気口7の周囲が前記壁部11によって囲まれていることによって、霧化した洗浄液Dが気流Fに乗って前記吸引管6に直接吸引されることが、ある程度防止される。このように、前記被洗浄箇所Aに洗浄液Dを吹き付けることで、前記被洗浄箇所Aの汚れが前記洗浄液Dに溶け出すか或いは前記洗浄液Dに分散する。なお、前記被洗浄箇所Aに吹き付けられた洗浄液Dは、前記スカート部5の縁5aが前記被洗浄箇所Aに密着し、更に前記領域S内の気圧が外気圧に対して低くなっていることから、前記スカート部5の縁5aと被洗浄箇所Aの当接箇所から外部に漏れることがない。更に、前記スカート部5の縁5aが被洗浄箇所Aから離れないように、前記洗浄具3を被洗浄箇所Aに沿って動かすことで、この被洗浄箇所Aは前記ブラシ部12によって擦られる。これによって、前記被洗浄箇所Aの汚れは良好に落とされ、前記洗浄液Dに溶け出すか或いは前記洗浄液Dに分散することになる。
【0014】
そして、前記汚れを含んだ洗浄液Dは、気流Fと共に前記吸引管6から前記吸引ホース2を経て、前記吸引手段1に吸い込まれ、この吸引手段1内で気流Fから分離される。なお、前記気流Fが前記壁部11と被洗浄箇所Aとの間を通過する際、前記洗浄液Dによって前記ブラシ12が濡れているため、前記気流Fは、比較的通過し難い、濡れた前記ブラシ12が形成された前記壁部11の先端11aと前記被洗浄箇所Aとの間を殆ど通過せずに、比較的通過し易い、前記ブラシ12が形成されていない前記壁部11の先端の一部11bと前記被洗浄箇所Aの間を大部分が通過することになる。このとき、前記気流Fは、前記壁部11の先端の一部11bと前記被洗浄箇所Aと前記ブラシ12によって囲まれた比較的狭い箇所を通過するため、この箇所においてもベンチュリ効果が生じ、前記被洗浄箇所A上の洗浄液Dを霧化して吸引することが期待できる。そして、このように吹き付けられた洗浄液Dが、前記スカート部5によって前記被洗浄箇所Aから掻き取られ、また前記被洗浄箇所Aから霧化した後に、前記吸引管6から吸引されることによって、前記洗浄具3が通過した後の被洗浄箇所Aは、前記洗浄液Dがほぼ除去された状態となる。
【0015】
そして、前記洗浄具3を被洗浄箇所Aから離すと、前記基体4の縁4aによって囲まれた開口部が開放されるため、気流Fは前記吸気口7ではなく、前記基体4の開口部から吸引されることになる。この結果、前記吸気口7を通過する気流Fの流量が激減し、前記ノズル13から洗浄液Dが吸引されなくなることで、この洗浄液Dの噴霧が停止する。
【0016】
以上のように本発明は、側部に吸引口たる吸引筒6が設けられると共に縁4aにスカート部5が設けられた基体4に、吸気口7と、この吸気口7に設けられたノズル13とを有する洗浄液供給手段17を設け、前記吸引筒6を前記吸引手段1に接続してこの吸引手段1を動作させ、前記スカート部5を被洗浄箇所Aに接触させることで前記基体4と被洗浄箇所Aとの間に形成された領域Sに前記吸気口7から流入する速い気流Fによってベンチュリ効果が生じ、ポンプ等を用いることなく、前記ノズル13から洗浄液Dを噴出させ、前記被洗浄箇所Aに吹き付けた後、汚れを含んだ洗浄液Dを前記吸引筒6から前記吸引手段1に吸引するものである。
【0017】
また本発明は、前記吸気口7に、気流の方向に対して徐々に狭くなる吸気入口部8と、この吸気入口部の下流側に隣接して流通面積の最も狭くなった絞り部9を設けたものであり、前記吸気口7から吸引される気流が吸気入口部8から絞り部9にスムーズに流れることで、洗浄液Dが前記ノズル13から効率的に噴出するものである。
【0018】
なお、本発明は以上の実施形態に限定されるものではなく、発明の要旨の範囲内で種々の変形が可能である。例えば、前述した実施形態において、前記ノズルは基体に対して取り付けられているが、前記ノズルを前記基体と一体に形成しても良い。また、前記ノズルを前記吸気口に対して複数設けても良く、前記吸気口を基体に対して複数設けても良い。更に、前記絞り部の絞り量を調整できるようにしても良い。
【0019】
【発明の効果】
本発明の請求項1に記載の洗浄装置は、被洗浄箇所を覆う基体と、この基体の縁に設けられて前記被洗浄箇所に接触するスカート部と、前記基体に設けられると共に吸引手段に接続される吸引口と、前記基体と被洗浄箇所で囲まれた領域に洗浄液を供給する洗浄液供給手段とを有する洗浄装置において、前記洗浄液供給手段が、前記基体に設けられた吸気口と、この吸気口に設けられたノズルとを有するものであり、前記スカート部を被洗浄箇所に当接させて前記吸引手段を動作させると、前記吸気口から基体と被洗浄箇所によって囲まれた空間を経て前記吸引口から吸引手段に至る速い気流が発生することで、この気流によって前記吸気口においてベンチュリ効果が生じ、このベンチュリ効果による負圧によって前記ノズルから洗浄液が噴出し、この噴出した洗浄液が被洗浄箇所に吹き付けられると共に、汚れた洗浄液が前記気流と一緒に前記吸引口から排出されるので、洗浄液を供給するためのポンプ等の動力源が不要となり、比較的単純で且つ小型の構造にすることができる。
【0020】
また、本発明の請求項2に記載の洗浄装置は、請求項1において、前記吸気口に、気流の方向に対して徐々に狭くなる吸気入口部と、この吸気入口部の下流側に隣接して流通面積が最も狭くなる絞り部を設けたものであり、前記吸引手段を動作させることによって発生した気流が前記吸気口の吸気入口部から絞り部にスムーズに流れるので、洗浄液を前記ノズルから効率的に噴出させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cleaning device that supplies a cleaning liquid to a portion to be cleaned and suctions dirty cleaning liquid by a suction source.
[0002]
[Problems to be solved by the invention]
Conventionally, for example, the following is known as this type of cleaning apparatus.
[0003]
[Patent Document 1]
JP-A-10-34095
This is achieved by forming a brush body (skirt portion) at an edge of a bowl-shaped base having a certain space inside, and providing a suction port (suction port) connected to a suction means on the base, and an external water supply means. Is formed, and water is sprayed from the spray nozzle to the body to be cleaned (location to be cleaned) by the water supply means, and dirty water is sucked into the suction means from the suction port. Note that a pump device is used as the water supply means. Further, there is also known a device in which pressurized water is ejected from an ejection nozzle by using exhaust gas of a suction unit.
[0005]
However, in such a washing device, a pump device or the like is required in the water supply system, or the exhaust of the suction means needs to be connected to the water supply system. There was a problem that it became complicated.
[0006]
An object of the present invention is to solve the above problems and to provide a relatively small cleaning apparatus having a simple structure.
[0007]
[Means for Solving the Problems]
A cleaning apparatus according to a first aspect of the present invention is a substrate that covers a site to be cleaned, a skirt provided on an edge of the substrate and in contact with the site to be cleaned, and connected to a suction unit provided on the substrate. A cleaning liquid supply means for supplying a cleaning liquid to a region surrounded by the base and the portion to be cleaned, wherein the cleaning liquid supply means includes an intake port provided in the base, And a nozzle provided in the mouth.
[0008]
According to the present invention, as described above, when the suction means is operated by bringing the skirt portion into contact with the portion to be cleaned, the suction is performed through the space surrounded by the base and the portion to be cleaned from the suction port. By generating a fast airflow from the mouth to the suction means, the airflow causes a Venturi effect at the suction port, and the negative pressure due to the Venturi effect causes the cleaning liquid to be jetted from the nozzle, and the jetted cleaning liquid is discharged to the portion to be cleaned. While being sprayed, the dirty cleaning liquid is discharged from the suction port together with the airflow.
[0009]
Further, in the cleaning device according to claim 2 of the present invention, in claim 1, the intake port is provided with an intake inlet portion gradually narrowing in a direction of an air flow, and a downstream side of the intake port portion. In this case, a narrowed portion is provided to minimize the flow area.
[0010]
With this configuration, the airflow generated by operating the suction unit flows smoothly from the intake port of the intake port to the throttle section.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 is a suction means. In addition, since the suction means 1 is a known vacuum cleaner capable of gas-liquid separation, detailed description of its structure is omitted. A cleaning tool 3 is detachably attached to the tip of the suction hose 2 of the suction means 1. A base 4 constituting the cleaning tool 3 is formed in a substantially container shape, and a skirt portion 5 made of synthetic rubber or the like is fixed to an edge 4a of the base 4. The skirt portion 5 is formed such that its edge 5a is on the same plane. Further, a suction pipe 6 serving as a suction port for connecting to the suction hose 2 of the suction means 1 is integrally formed on a side portion of the base 4. Further, an intake port 7 is formed substantially at the center of the base 4. The intake port 7 is formed so as to be gradually narrowed in the direction of the airflow F, the throttle section 9 having the smallest flow area, and gradually widened in the direction of the airflow F. And the suction outlet section 10 formed as described above. A short cylindrical wall portion 11 is formed inside the base 4 so as to surround the intake port 7. A brush portion 12 is formed at a tip 11a of the wall portion 11 except for a part 11b thereof. When the skirt portion 5 of the cleaning tool 3 is brought into contact with the flat portion A to be cleaned. In addition, the tip 11a is formed so as to approach the location A to be cleaned, and the brush portion 12 is formed so as to contact the location A to be cleaned. Further, a nozzle 13 is provided in the throttle section 9 of the intake port 7. The nozzle 13 is in communication with a connection pipe 14 protruding from the base 4. Further, the connection pipe 14 is connected to a cleaning liquid container 16 via a cleaning liquid supply pipe 15. The nozzle 13, the connection pipe 14, the cleaning liquid supply pipe 15 and the cleaning liquid container 16 constitute a cleaning liquid supply unit 17.
[0012]
Next, the operation of the present embodiment will be described. First, the user connects the suction pipe 6 of the cleaning tool 3 to the suction hose 2 of the suction means 1. Further, the cleaning liquid D is put into the cleaning liquid container 16 and the cleaning liquid supply pipe 15 is connected to the connection pipe 14. Note that a solvent such as water, a diluted detergent, or the like is used as the cleaning liquid D. When the suction device 1 is operated by gripping the cleaning tool 3, the outside of the opening surrounded by the edge 4 a of the base 4 is passed through the opening, the suction pipe 6, and the suction hose 2. An airflow F flowing through the suction means 1 is generated. At this time, air is sucked from the vicinity of the opening of the base 4 and air flows from the vicinity of the opening so as to supplement the sucked air. There is almost no amount that flows from the front side (the left side in FIG. 2) of the opening of the base 4 that is widely opened, and flows into the vicinity of the opening of the base 4 through the intake port 7 having a small opening area. That is, in this state, the airflow F simply flows from the opening of the base 4 to the suction means 1 via the suction pipe 6 and the suction hose.
[0013]
Then, when the user presses the cleaning tool 3 against the portion A to be cleaned so that the entire edge 5a of the skirt portion 5 contacts the flat portion A to be cleaned, the portion A to be cleaned, the base 4, and the skirt The region S surrounded by the portion 5 is in a state of communicating with the outside only by the intake port 7. At this time, since the entire edge 5a of the skirt portion 5 is in contact with the portion to be cleaned A, air outside the base 4 cannot be sucked into the region S from the opening of the base 4. Only, the air is sucked into the region S from the suction port 7 and becomes the airflow F, and flows into the suction pipe 6 through the gap between the wall portion 11 and the portion A to be cleaned. When the airflow F passes through the throttle section 9 through the intake port 8 of the intake port 7, the flow velocity increases due to the Venturi effect and a negative pressure is generated. Then, when a negative pressure is generated in the throttle unit 9, the cleaning liquid D is sucked from the nozzle 13 and atomized by the fast airflow F. Then, the atomized cleaning liquid D rides on the airflow F and is sprayed relatively evenly on the portion A to be cleaned. In addition, since the periphery of the air inlet 7 is surrounded by the wall 11, it is possible to prevent the atomized cleaning liquid D from being directly sucked into the suction pipe 6 on the air flow F. In this way, by spraying the cleaning liquid D onto the location A to be cleaned, the dirt on the location A to be cleaned dissolves in the cleaning liquid D or is dispersed in the cleaning liquid D. The cleaning liquid D sprayed on the location A to be cleaned is such that the edge 5a of the skirt portion 5 is in close contact with the location A to be cleaned, and the pressure in the region S is lower than the outside pressure. As a result, there is no leakage to the outside from the contact point between the edge 5a of the skirt portion 5 and the portion A to be cleaned. Further, by moving the cleaning tool 3 along the portion A to be cleaned so that the edge 5a of the skirt portion 5 does not separate from the portion A to be cleaned, the portion A to be cleaned is rubbed by the brush portion 12. As a result, the dirt at the portion A to be cleaned is satisfactorily removed, and is dissolved in the cleaning liquid D or dispersed in the cleaning liquid D.
[0014]
Then, the cleaning liquid D containing the dirt is sucked into the suction unit 1 from the suction pipe 6 through the suction hose 2 together with the airflow F, and is separated from the airflow F in the suction unit 1. When the airflow F passes between the wall portion 11 and the location A to be cleaned, the brush 12 is wet by the cleaning liquid D, so that the airflow F is relatively hard to pass, and The tip of the wall portion 11 where the brush 12 is not formed is relatively easy to pass through, without substantially passing between the tip 11a of the wall portion 11 where the brush 12 is formed and the location A to be cleaned. Most of the space passes between the portion 11b and the portion A to be cleaned. At this time, since the airflow F passes through a relatively narrow portion surrounded by the portion 11b at the tip of the wall portion 11, the portion A to be cleaned, and the brush 12, the venturi effect also occurs at this portion, It can be expected that the cleaning liquid D on the portion A to be cleaned is atomized and sucked. Then, the cleaning liquid D sprayed in this manner is scraped off from the location A to be cleaned by the skirt portion 5, and is atomized from the location A to be cleaned, and then is sucked from the suction pipe 6. The portion A to be cleaned after the cleaning tool 3 has passed is in a state where the cleaning liquid D has been substantially removed.
[0015]
When the cleaning tool 3 is separated from the portion A to be cleaned, the opening surrounded by the edge 4a of the base 4 is opened, so that the airflow F flows from the opening of the base 4 instead of the intake port 7. It will be sucked. As a result, the flow rate of the air flow F passing through the suction port 7 is drastically reduced, and the cleaning liquid D is stopped being sucked from the nozzle 13, so that the spraying of the cleaning liquid D is stopped.
[0016]
As described above, according to the present invention, the suction port 7 and the nozzle 13 provided in the suction port 7 are provided on the base 4 having the suction tube 6 serving as a suction port on the side and the skirt portion 5 provided on the edge 4a. The suction tube 6 is connected to the suction unit 1 and the suction unit 1 is operated to bring the skirt portion 5 into contact with the portion A to be cleaned. The fast air flow F flowing from the suction port 7 into the region S formed between the cleaning location A and the cleaning location A causes a Venturi effect, and the cleaning liquid D is ejected from the nozzle 13 without using a pump or the like, and After spraying the cleaning liquid A, the cleaning liquid D containing dirt is sucked from the suction cylinder 6 to the suction means 1.
[0017]
In the present invention, the intake port 7 is provided with an intake port 8 gradually narrowing in the direction of the air flow, and a throttle section 9 having a narrowest flow area adjacent to the downstream side of the intake port. The cleaning liquid D is efficiently ejected from the nozzles 13 by smoothly flowing the airflow sucked from the suction port 7 to the throttle section 9 from the suction inlet section 8.
[0018]
Note that the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in the above-described embodiment, the nozzle is attached to the base, but the nozzle may be formed integrally with the base. Further, a plurality of the nozzles may be provided for the intake port, and a plurality of the intake ports may be provided for the base. Further, the aperture amount of the aperture section may be adjustable.
[0019]
【The invention's effect】
A cleaning apparatus according to a first aspect of the present invention is a substrate that covers a site to be cleaned, a skirt provided on an edge of the substrate and in contact with the site to be cleaned, and connected to a suction unit provided on the substrate. A cleaning liquid supply means for supplying a cleaning liquid to a region surrounded by the base and the portion to be cleaned, wherein the cleaning liquid supply means includes an intake port provided in the base, A nozzle provided in the mouth, and when the suction means is operated by bringing the skirt portion into contact with the location to be cleaned, the suction port passes through the space surrounded by the base and the location to be cleaned from the suction port. By generating a fast airflow from the suction port to the suction means, the airflow causes a Venturi effect in the suction port, and the negative pressure due to the Venturi effect causes the cleaning liquid to be ejected from the nozzle. Then, the jetted cleaning liquid is sprayed onto the portion to be cleaned, and the dirty cleaning liquid is discharged from the suction port together with the airflow, so that a power source such as a pump for supplying the cleaning liquid is not necessary, and the cleaning liquid is relatively unnecessary. A simple and compact structure can be achieved.
[0020]
Further, in the cleaning device according to claim 2 of the present invention, in claim 1, the intake port is provided with an intake inlet portion gradually narrowing in a direction of an air flow, and a downstream side of the intake port portion. The air flow generated by operating the suction means flows smoothly from the intake port of the intake port to the throttle section, so that the cleaning liquid is efficiently discharged from the nozzle. Can be spouted.
