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。
箱体１の給水接続口１１に、水道の蛇口２１に接続された可撓性ホース２２が連結されており、給水接続口１１とタンク４の入口は、箱体内給水管１０によって連通連結されている。タンク４の入口には、定水位弁（ボールタップ）２０が設けられている。定水位弁（ボールタップ）２０は、タンク４内の水面が所定の高さを下回ると、開弁して、給水管１０からタンク４に水道水が供給される。タンク４内の水面が所定の高さに戻ると、弁を閉じて、タンク４への水道水の供給が停止される。ポンプ２の下流側に設けられた圧送管１２の吐出接続口１３に、可撓性高圧ホース６を接続し、この高圧ホース６の先端に洗浄ガン８が連通連結されている。洗浄ガン８の先端には噴射ノズル９が設けられている。 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
As shown in FIG. 1, the cleaning apparatus of the present invention is used for cleaning automobiles and the like, and includes 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 an engine 3 for rotationally driving the pump 2 is built in (internally provided) in the box 1.
A flexible hose 22 connected to a tap faucet 21 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 connected and connected by a water supply pipe 10 in the box. Yes. A constant water level valve (ball tap) 20 is provided at the inlet of the tank 4. When the water level in the tank 4 falls below a predetermined height, the constant water level valve (ball tap) 20 opens and tap water is supplied from the water supply pipe 10 to the tank 4. When the water level 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 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 in-box water supply pipe 10 is disposed in close proximity to at least the high temperature portion 3 </ b> A of the engine 3.
The high temperature part 3A of the engine 3 indicates a muffler 30 provided on the upper part and a heat radiation (exhaust heat) fin 31 provided on the upper side surface. The output shaft of the engine 3 is connected to the rotation shaft of the pump 2 and rotationally drives the pump 2. The water supply pipe 10 is not in direct contact with the high temperature part 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 disposed in a surrounding shape in the high temperature portion 3 </ b> A of the engine 3.
The spiral pipe portion 15 is formed by bending a metal pipe having a diameter of 10 mm to 25 mm in a spiral shape. 2 and 3, the spiral pipe portion 15 has an inner and outer double spiral structure, and the bent pipes have a vertical gap between each other, and air can easily pass through the gap (from the outside to the inside). Is well formed).
The water supply pipe 10 is also provided in a surrounding manner at the lower part of the engine 3. Although it is predicted that there is no direct heat generation from the lower part of the engine 3, it is more efficient and preferable to surround the entire engine 3 including the lower part because there is heat conduction from the upper high temperature part 3A. 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 portion 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 1 has a rectangular parallelepiped shape, has a plurality of casters 16 at the lower portion, and can be manually driven. A flexible high-pressure hose 6 connected to the cleaning gun 8 is provided on the box 1 so as to extend outward. The box 1 has an opening 14 for taking in air from the outside at a location corresponding to the intake port or fin 31 of the engine 3. The opening hole 14 is provided with a louver. A blower fan may be provided inside the wall surface of the box 1 corresponding to the opening hole 14. External air is taken in from the opening 14 by natural intake or by intake by a blower fan, and is supplied to the intake port and the fin 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 use method (action) of the above-described cleaning apparatus of the present invention will be described.
As shown in FIG. 1, the pump 2 is rotationally driven by the engine 3, and water W (cleaning water) is sprayed from the spray 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 in the spiral pipe portion 15 that is close to and faces the high temperature portion 3A, and the rising of tap water flowing through the spiral pipe portion 15 is increased. The tap water flows into the tank 4 while absorbing the amount of heat by the temperature. That is, the water supply pipe 10 collects heat (atmosphere heat) from the surroundings of the engine 3 and conveys 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 jetting water W (cleaning water) from the cleaning gun 8. In this way, the heat generated in the engine 3 with the operation of the pump 2 is discharged to the outside of the box 1, and the air in the box 1 is prevented from becoming high temperature.

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 the relatively low temperature air taken from the outside of the box body 1 is smoothly carried on the wind Z without blocking the flow of the wind Z. To the intake port of the engine 3 and the fins 31.

なお、本発明は、設計変更可能であって、例えば、給水管１０は、金属製パイプを複数回にわたって折り返した形状（図６参照）や、エンジン３を取り囲む柵のような形状（図７参照）に形成しても良い。
また、（図示省略するが、）図２、図３、あるいは、図６、図７に示した箱体内給水管１０を支持する金属杆等を、エンジン３の高温部位３Ａに、固着して、熱の伝導によって、エンジン３の高温部位３Ａの熱を給水管１０に伝達させるも、好ましい。 The design of the present invention can be changed. For example, the water supply pipe 10 has a shape in which a metal pipe is folded back several times (see FIG. 6) or a shape like a fence surrounding the engine 3 (see FIG. 7). ).
Further, although not shown, a metal rod or the like that supports the in-box water supply pipe 10 shown in FIG. 2, FIG. 3, or FIG. 6, FIG. It is also preferable to transfer the heat of the hot part 3A of the engine 3 to the water supply pipe 10 by heat conduction.

以上のように、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 apparatus according to the present invention includes the water storage tank 4 to which tap water is supplied from the outside, the pump 2 that pumps the water W in the tank 4 to the external cleaning gun 8, and the pump 2. In the cleaning device provided in the box 1, the water supply pipe 10 for supplying tap water to the tank 4 is opposed to at least the high temperature part 3 </ b> A of the engine 3. Therefore, tap water supplied to the tank 4 from the outside flows into the water supply pipe 10, so that heat is taken away from the high temperature portion 3 </ b> A of the engine 3 and discharged by the injection of water W from the cleaning gun 8. Can heat. Overheating of the engine 3 can be prevented and the life of the engine oil can be extended. No radiator is required, and the cost can be reduced with a simple structure. Using the water W used for washing automobiles or the like, the high temperature portion 3A of the engine 3 can be cooled, 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 pump operating state where 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. Since the water W inside is jetted from the cleaning gun 8 and the air in the box 1 is prevented from becoming high temperature, the radiant heat (radiant heat) of the high temperature portion 3A is supplied to the water supply pipe. The heat (atmospheric heat) can be removed from the surroundings of the engine 3 by being reliably received by the portion (helical pipe portion 15) facing the high temperature portion 3A. The amount of heat stored in the tank 4 together with the water W can be discharged from the cleaning gun 8 to the outside of the box 1 by jetting water W (cleaning water).

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 disposed in a surrounding manner at the high temperature portion 3A of the engine 3, it receives radiant heat (radiant heat) from the high temperature portion 3A of the engine 3. Thus, heat can be efficiently recovered.
