特許文献1記載の洗浄装置は、ポンプの稼働時にエンジンで発生する熱によって、箱体内が高温になってしまう虞れがある。そのまま運転を続けると、エンジンのオーバーヒートや、高熱によってエンジンオイルが早期に劣化するという問題が発生する。
一般的に、自動車のエンジンには、ラジエータ(冷却装置)が設けられているが、特許文献1記載のような洗浄装置は、走行して風を受けるものではないので、ラジエータを付設しても、その冷却効果が得られなかった。
In the cleaning device described in Patent Document 1, there is a possibility that the inside of the box becomes hot due to the heat generated by the engine when the pump is in operation. If the operation is continued as it is, there will be a problem that the engine oil deteriorates early due to overheating of the engine and high heat.
Generally, an automobile engine is provided with a radiator (cooling device), but a cleaning device as described in Patent Document 1 does not run and receive wind, so even if a radiator is attached. , The cooling effect was not obtained.

そこで、本発明は、水道から供給される水道水を利用して、箱体内が高温となるのを抑制できる洗浄装置を提供することを目的とする。 Therefore, an object of the present invention is to provide a cleaning device capable of suppressing the temperature inside the box from becoming high by using tap water supplied from tap water.

以下、実施の形態を示す図面に基づき本発明を詳説する。
図1に示すように、本発明の洗浄装置は、自動車等の洗浄に使用されるものであって、貯水用タンク4と、タンク4内の水Wを吸い込んで洗浄ガン8に圧送するポンプ2と、ポンプ2を回転駆動するエンジン3とを、箱体1に内蔵(内設)している。

Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments.
As shown in FIG. 1, the cleaning device of the present invention is used for cleaning an automobile or the like, and is a water storage tank 4 and a pump 2 that sucks water W in the tank 4 and pumps it to a cleaning gun 8. And the engine 3 that rotationally drives the pump 2 are built in (internally) in the box body 1.
A flexible hose 22 connected to the faucet 21 of the water supply is connected to the water supply connection port 11 of the box body 1, and the water supply connection port 11 and the inlet of the tank 4 are communicated and connected by the water supply pipe 10 inside the box. There is. A constant water level valve (ball tap) 20 is provided at the inlet of the tank 4. The constant water level valve (ball tap) 20 opens when the water surface in the tank 4 falls below a predetermined height, and tap water is supplied from the water supply pipe 10 to the tank 4. When the water surface in the tank 4 returns to a predetermined height, the valve is closed and the supply of tap water to the tank 4 is stopped. A flexible high-pressure hose 6 is connected to a discharge connection port 13 of a pressure feed pipe 12 provided on the downstream side of the pump 2, and a cleaning gun 8 is communicated and connected to the tip of the high-pressure hose 6. An injection nozzle 9 is provided at the tip of the cleaning gun 8.

図2~図4に示すように、箱体内給水管10は、エンジン3の少なくとも高温部位3Aに接近状に対向して配設されている。
エンジン3の高温部位3Aとは、上部に設けられたマフラー30や、上部側面に設けられた放熱(排熱)用フィン31を示している。エンジン3は、その出力軸がポンプ2の回転軸に連結され、ポンプ2を回転駆動する。なお、給水管10は、エンジン3の高温部位3Aとは直に接していない。
As shown in FIGS. 2 to 4, the water supply pipe 10 inside the box is arranged so as to face at least the high temperature portion 3A of the engine 3 so as to approach each other.
The high temperature portion 3A of the engine 3 indicates a muffler 30 provided on the upper portion and a heat dissipation (exhaust heat) fin 31 provided on the upper side surface. The output shaft of the engine 3 is connected to the rotating shaft of the pump 2, and the pump 2 is driven to rotate. The water supply pipe 10 is not in direct contact with the high temperature portion 3A of the engine 3.

給水管10は、エンジン3の高温部位3Aに包囲状に配設された螺旋状パイプ部15を有している。
螺旋状パイプ部15は、直径が10mm~25mmの金属製パイプを螺旋状に弯曲させて形成されている。図2と図3では、螺旋状パイプ部15は、内外2重螺旋構造であって、弯曲したパイプどうしが相互に上下方向の隙間を空けて、この隙間から空気が通過し易く(外側から内側への風通しが良く)形成されている。
また、給水管10は、エンジン3の下部にも包囲状に設けられている。エンジン3の下部からは直接的な発熱が無いと予測されるが、上部の高温部位3Aからの熱伝導があるため、下部を含めたエンジン3全体を包囲する方が、効率が良く、好ましい。なお、給水管10は、上部の高温部位3Aに対向する部位(螺旋状パイプ部15)と、エンジン3の下部に対向する部位とが、エンジン3とポンプ2の連結部を避けるように、間隔を空けて形成されている。
The water supply pipe 10 has a spiral pipe portion 15 arranged in a surrounding shape in the high temperature portion 3A of the engine 3.
The spiral pipe portion 15 is formed by spirally bending a metal pipe having a diameter of 10 mm to 25 mm. In FIGS. 2 and 3, the spiral pipe portion 15 has an inner / outer double helix structure, and the curved pipes each have a vertical gap between them, and air can easily pass through this gap (from the outside to the inside). (Good ventilation to) is formed.
Further, the water supply pipe 10 is also provided in a surrounding shape in the lower part of the engine 3. It is predicted that there will be no direct heat generation from the lower part of the engine 3, but since there is heat conduction from the upper high temperature portion 3A, it is more efficient and preferable to surround the entire engine 3 including the lower part. The water supply pipe 10 is spaced so that the portion facing the upper high temperature portion 3A (spiral pipe portion 15) and the portion facing the lower part of the engine 3 avoid the connecting portion between the engine 3 and the pump 2. It is formed with a gap.

図5に示すように、箱体1は、直方体状であって、下部に複数のキャスター16を有し、手動走行可能である。洗浄ガン8に連結される可撓性高圧ホース6が、箱体1に外方延伸状に設けられている。箱体1は、エンジン3の吸気口又はフィン31に対応する箇所に、外部から空気を取り込むための開口孔部14が形成されている。開口孔部14には、ルーバーが設けられている。この開口孔部14に対応する箱体1の壁面内部に、送風ファンを付設しても良い。この開口孔部14から自然吸気にて、又は、送風ファンによる吸気によって、外部の空気を取り込んで、エンジン3の吸気口やフィン31に供給している。 As shown in FIG. 5, the box body 1 has a rectangular parallelepiped shape, has a plurality of casters 16 at the lower portion, and can be manually traveled. A flexible high-pressure hose 6 connected to the cleaning gun 8 is provided in the box body 1 in an outwardly extending shape. The box body 1 is formed with an opening hole 14 for taking in air from the outside at a position corresponding to the intake port of the engine 3 or the fin 31. A louver is provided in the opening hole 14. A blower fan may be provided inside the wall surface of the box body 1 corresponding to the opening hole 14. External air is taken in from the opening hole 14 by natural aspiration or by intake by a blower fan, and is supplied to the intake port and fins 31 of the engine 3.

上述した本発明の洗浄装置の使用方法(作用)について説明する。
図1に示すように、エンジン3によってポンプ2が回転駆動されて、洗浄ガン8の先端の噴射ノズル9から水W(洗浄水)が噴射する。このポンプ稼働状態下で、タンク4に給水管10から水道水が供給される。この際、給水管10は、エンジン3の高温部位3Aからの放射熱(輻射熱)を、高温部位3Aに接近対向する螺旋状パイプ部15に受けて、螺旋状パイプ部15を流れる水道水の昇温によって熱量を吸収しつつ、水道水がタンク4に流入する。即ち、給水管10は、エンジン3の周囲から熱(雰囲気熱)を回収し、水道水と共に熱量をタンク4に搬送する。タンク4の水Wと共に蓄えられた熱量は、洗浄ガン8から水W(洗浄水)の噴射によって、排熱される。このようにして、ポンプ2の稼働に伴ってエンジン3で発生する熱を箱体1外へ排出し、箱体1内の空気が高温になるのを抑制する。
The method (action) of using the cleaning device of the present invention described above will be described.
As shown in FIG. 1, the pump 2 is rotationally driven by the engine 3, and water W (cleaning water) is injected from the injection nozzle 9 at the tip of the cleaning gun 8. Under this pump operating state, tap water is supplied to the tank 4 from the water supply pipe 10. At this time, the water supply pipe 10 receives the radiant heat (radiant heat) from the high temperature portion 3A of the engine 3 to the spiral pipe portion 15 approaching and opposed to the high temperature portion 3A, and the tap water flowing through the spiral pipe portion 15 rises. Tap water flows into the tank 4 while absorbing heat depending on the temperature. That is, the water supply pipe 10 recovers heat (atmospheric heat) from the periphery of the engine 3 and conveys the amount of heat to the tank 4 together with tap water. The amount of heat stored together with the water W in the tank 4 is exhausted by the injection of the water W (washing water) from the washing gun 8. In this way, the heat generated by the engine 3 with the operation of the pump 2 is discharged to the outside of the box body 1 to suppress the temperature of the air inside the box body 1 from becoming high.

図2に示すように、箱体1の外部から開口孔部14を通過した風Zが、エンジン3の吸気口やフィン31に向けて吹き込んで、エンジン3を冷却する。給水管10(螺旋状パイプ部15)は、外側から内側への風通しが良く、風Zの流れを遮ることなく、箱体1外部から取り込んだ比較的低温の空気が、風Zに乗ってスムーズにエンジン3の吸気口やフィン31に供給される As shown in FIG. 2, the wind Z that has passed through the opening hole 14 from the outside of the box body 1 blows toward the intake port and the fin 31 of the engine 3 to cool the engine 3. The water supply pipe 10 (spiral pipe portion 15) has good ventilation from the outside to the inside, and relatively low-temperature air taken in from the outside of the box 1 is smoothly carried on the wind Z without blocking the flow of the wind Z. It is supplied to the intake port of the engine 3 and the fin 31 .

上のように、本発明に係る洗浄装置は、水道水が外部から供給される貯水用タンク4と、該タンク4内の水Wを外部の洗浄ガン8に圧送するポンプ2と、該ポンプ2を回転駆動するエンジン3とを、箱体1内に設けた洗浄装置に於て、上記タンク4に水道水を供給する給水管10が、上記エンジン3の少なくとも高温部位3Aに接近状に対向して配設されているので、外部からタンク4に供給される水道水が給水管10に流れることで、エンジン3の高温部位3Aから熱を奪って、洗浄ガン8からの水Wの噴射によって排熱できる。エンジン3のオーバーヒートを防止でき、かつ、エンジンオイルの寿命を延ばすことができる。ラジエータが不要で、簡素な構造で、コストを低減できる。自動車等の洗浄に使用するための水Wを利用して、エンジン3の高温部位3Aを冷却でき、無駄が無い。 As described above , the cleaning device according to the present invention includes a water storage tank 4 to which tap water is supplied from the outside, a pump 2 that pumps water W in the tank 4 to an external cleaning gun 8, and the pump. In the cleaning device provided in the box body 1 with the engine 3 for driving the rotation of 2, the water supply pipe 10 for supplying tap water to the tank 4 faces at least the high temperature portion 3A of the engine 3 in an approaching manner. Since tap water supplied to the tank 4 from the outside flows to the water supply pipe 10, heat is taken from the high temperature portion 3A of the engine 3 and the water W is injected from the cleaning gun 8. You can exhaust heat. Overheating of the engine 3 can be prevented, and the life of the engine oil can be extended. No radiator is required, the structure is simple, and the cost can be reduced. The high temperature portion 3A of the engine 3 can be cooled by using the water W used for cleaning an automobile or the like, and there is no waste.

また、上記ポンプ2が回転するポンプ稼働状態下で、上記高温部位3Aの熱を、上記給水管10を流れる水道水の昇温によって吸収して、上記タンク4に供給されると共に、該タンク4内の水Wが上記洗浄ガン8から噴射されて、上記箱体1内の空気が高温となるのを抑制するように構成されているので、高温部位3Aの放射熱(輻射熱)を、給水管10の高温部位3Aに対向する部位(螺旋状パイプ部15)にて確実に受けて、エンジン3の周囲から熱(雰囲気熱)を取り除くことができる。タンク4に水Wと共に蓄えられた熱量を、洗浄ガン8から水W(洗浄水)の噴射によって、箱体1の外部へ排出できる。 Further, under the operating state of the pump in which the pump 2 rotates, the heat of the high temperature portion 3A is absorbed by the temperature rise of the tap water flowing through the water supply pipe 10 and supplied to the tank 4 and the tank 4 is also supplied. Since the water W inside is ejected from the cleaning gun 8 and is configured to suppress the temperature of the air inside the box 1 from becoming high, the radiant heat (radiant heat) of the high temperature portion 3A is transferred to the water supply pipe. The heat (atmospheric heat) can be removed from the periphery of the engine 3 by reliably receiving the heat at the portion (spiral pipe portion 15) facing the high temperature portion 3A of 10. The amount of heat stored together with the water W in the tank 4 can be discharged to the outside of the box 1 by injecting the water W (washing water) from the washing gun 8.

また、上記給水管10は、上記エンジン3の上記高温部位3Aに包囲状に配設された螺旋状パイプ部15を有しているので、エンジン3の高温部位3Aから放射熱(輻射熱)を受けて、効率よく熱を回収することができる。 Further, since the water supply pipe 10 has a spiral pipe portion 15 arranged in a surrounding shape around the high temperature portion 3A of the engine 3, radiant heat (radiant heat) is received from the high temperature portion 3A of the engine 3. Therefore, heat can be efficiently recovered.
