Description

[Detailed explanation of the idea] The present invention relates to an improvement of a floor cleaning vehicle.

As shown in Fig. 3, a floor cleaning vehicle that cleans dust while traveling on the floor is equipped with a dust box 1' at the front of a vehicle body 4' with a driver's seat 10' at the rear. The exhaust port 3' of the connected blower 2' is opened toward the outside of the vehicle body 4', and an engine 5' is installed at the rear of the vehicle body 4'. A fan 6', a radiator 8',
Usually, a cooling unit 7' consisting of an oil cooler 9' or the like is installed sequentially in the front and back, but the engine 5' is cooled by the cooling unit 7' using only outside air sucked in from the rear of the vehicle body 4'. As a result, the cooling efficiency is low, and the outside air sucked in from the rear becomes hot air by cooling the engine 5', and a part of it is sent to the driver's seat 10' side, which is also located at the rear of the vehicle body 4', thereby reducing the work environment. There are drawbacks that make it worse.

The present invention was completed with the aim of providing a floor cleaning vehicle that does not have the above-mentioned drawbacks, and the embodiment shown in FIGS. 1 and 2 will be described in detail below.

4 is a vehicle body provided with a dust box 1 at the front and a driver's seat 10 at the rear;
An exhaust port 3 of a blower 2 connected to the rear of the vehicle body 4 is opened in front of an engine 5 provided at the rear end of the vehicle body 4.

Further, a cooling unit 7 is provided between the blower 2 and the engine 5ε, and includes a fan 6 for sucking outside air to join the exhaust airflow of the blower 2 and direct it toward the engine 5.

In addition, 8 and 9 are a radiator and an oil cooler that constitute the cooling unit 7 together with the fan 6, 11 is a main brush provided at the bottom of the vehicle body 4 facing the suction port of the dust box 1, and 12 is a front side of the vehicle body 4. 13 is a wheel, and 14 is a filter for dust sucked by the blower 2.

With this structure, the vehicle body 4 is driven by an engine 5 provided at the rear end of the vehicle and travels on the floor, and the dust on the floor is connected to the rear of the dust box 1 provided at the front of the vehicle body 4. The dust box 1 is removed by the operation of the blower 2.
The exhaust port 3 of the blower 2 connected to the rear of the dust box 1 is opened in front of the engine 5 provided at the rear end of the vehicle body 4. Therefore, the exhaust airflow from the exhaust port 3 is directed toward the engine 5 to cool it, and a cooling unit 7 is provided between the blower 2 and the engine 5 to cool the engine 5. Since the unit 7 is equipped with a fan 6 for sucking outside air to join the exhaust airflow from the exhaust port 3 of the blower 2 and direct it toward the engine 5, the suction introduced through the unit 7 by the fan 6 is The outside air is combined with the exhaust airflow from the blower 2 that is blown toward the engine 5, so that the cooling efficiency of the engine 5 is significantly improved.

Note that in order to make the outside air sucked by the fan 6 join the exhaust airflow of the blower 2 and direct it to the engine 5, the axis of the fan 6 is positioned, for example, in a direction perpendicular to the direction in which the exhaust airflow of the blower 2 is discharged. Just do it like this.

Therefore, the exhaust airflow after cooling the engine 5 as described above flows between the engine 5 and the driver's seat provided at the rear of the vehicle body 4.
Since an air curtain is formed between the exhaust gas and the exhaust gas and the exhaust air flows toward the rear of the vehicle body 4, hot air from the exhaust airflow is prevented from reaching the driver's seat 10, and the working environment can be maintained comfortably at all times. .

Therefore, the present invention has great practical value as it eliminates the drawbacks of conventional floor cleaning vehicles of this type.
