め洗浄水を一定以上の熱量で加熱することができる。According to the structure of the second aspect of the present invention, when the flow rate of the wash water ejected from the nozzle is reduced by the flow rate control valve, the pressure control valve acts so as to flow back to the wash water tank through the bypass passage. The flow rate of wash water increases. As a result, the temperature of the wash water in the wash water tank becomes high, and the temperature of the wash water jetted from the jet nozzle becomes high.
On the other hand, if the flow rate of the wash water jetted from the jet nozzle is increased by the flow rate control valve, the amount of heated wash water that flows back to the wash water tank through the bypass passage is reduced due to the action of the pressure control valve. As a result, the temperature of the cleaning water ejected from the ejection nozzle is lowered. That is, if the flow rate of the cleaning water jetted is reduced, the temperature of the cleaning water rises, and if the flow rate of the cleaning water jetted is increased, the temperature of the wash water decreases. Moreover, even if the discharge side of the pump is connected to the tank, the pressure on the discharge side of the pump does not decrease due to the provision of the pressure control valve. As a result, the cleaning water pressure does not decrease, the cleaning effect does not decrease, and the engine load does not decrease, so that the cleaning water can be heated with a certain amount of heat or more.

The wash water pump 4 is connected to a wash water tank 7 via a pipe 6 and is connected to a jet nozzle 9 via a pipe 8. The wash water is stored in the wash water tank 7. A cleaning agent or the like may be appropriately mixed in the cleaning water. Further, in order to keep the amount of water stored in the wash water tank 7 constant, a liquid level detection sensor 10 is attached to the wash water tank 7, and the sensor 10 is a pump device for supplying wash water from a water source 11 to the tank 7. 1
Connected to 2. The cooling water pump 5 is connected to a circulation pipe 15 for circulating engine cooling water, and the pipe 15 is connected to an inlet 2 a and an outlet 2 b of cooling water of the engine 2. A first heat exchanger 13 that exchanges heat between the engine cooling water flowing in the pipe 15 and the exhaust gas in the exhaust pipe 16 of the engine 2 is provided, and the cooling water that has cooled the engine 2 is changed by the exhaust gas. Be heated. A second heat exchanger 14 for exchanging heat between the heated engine cooling water flowing in the pipe 15 and the cleaning water flowing in the pipe 6 is provided, and the cleaning water is heated by the engine cooling water. As a result, the wash water is heated by the heat of the exhaust gas and the heat of the engine cooling water.

ク７に還流する洗浄水流量が多くなる。The pipe 8 connecting the wash water pump 4 and the nozzle 9 is branched on the way, and the branch pipe 18 is connected to the wash water tank. As a result, a bypass flow path for guiding a part of the wash water sent from the wash water pump 4 to the nozzle 9 to the wash water tank 7 is formed. A pressure control valve 19 is provided in the middle of the branch pipe 18 forming the bypass flow path. The pressure control valve 19 opens the branch pipe 18 when the pressure acting on the upstream side exceeds a certain set value, and closes the branch pipe 18 at a set value or less. As a result, if the flow rate of cleaning water ejected from the nozzle 9 by the flow rate control valve 17 is increased, the tank 7 is removed from the bypass passage.
The flow rate of the wash water flowing back to the tank 7 decreases, and the flow rate of the wash water ejected from the nozzle 9 decreases to increase the flow rate of the wash water flowing back to the tank 7 from the bypass passage.

Therefore, it is possible to reduce the size and fuel consumption. Further, since the heat of the engine cooling water is radiated by the second heat exchanger 14, it is not necessary to separately provide a cooling fan for heat radiation, and noise can be reduced.

Since the flow rate of the heated wash water flowing back to the tank 7 through the nozzle increases, the temperature of the wash water ejected from the nozzle 9 rises, while the flow rate of the wash water ejected from the nozzle 9 is increased by the flow control valve 17. Since the flow rate of the heated cleaning water flowing back to the tank 7 through the bypass flow path 18 decreases, the temperature of the cleaning water ejected from the nozzle 9 decreases. That is, the cleaning water temperature can be adjusted only by adjusting the flow rate of the cleaning water ejected from the nozzle 9 by the flow rate adjusting valve 17.
Even if the discharge side of the wash water pump 4 is connected to the tank 7, the pressure adjustment valve 19 does not reduce the pressure of jetting wash water from the nozzles 17 and does not reduce the washing effect. Further, since the load of the engine 2 for driving the wash water pump 4 does not decrease, the exhaust gas temperature and the cooling water temperature of the engine 2 do not decrease. Further, in the above embodiment, the same amount of wash water as the wash water ejected from the nozzle 9 is replenished to the wash water tank 7, so that a constant amount of wash water is always circulated and ejected from the nozzle 9. The wash water temperature can be controlled stably.

The fuel consumption can be reduced, the running cost can be reduced, and the risk of ignition of the flammable cleaning agent can be reduced.
