TECHNICAL FIELD The present application relates to a waste treatment device for a vehicle.

2. Description of the Related Art Conventionally, as a vehicle sewage treatment device, initial water is stored in about half of the tank, the water is used as toilet flush water, and then returned to the tank along with the sewage, and a simple filter is installed in the tank. It is equipped with a filter that filters wastewater with this filter, uses the pump to reuse it as wash water for the toilet, and a circulation type that only uses fresh water to wash the toilet bowl, and then clean it with the waste tank. There is a separate type that is housed in.

The problem to be solved by the invention is, however, that in the case of a circulation type treatment device, deodorant disinfectant must be used because sewage is mixed in.
It has the drawback of not being hygienic, and in the case of a separation type treatment device, it is hygienic, but on the other hand, it is necessary to equip a tank for clean water and a tank for sewage, which is heavy and requires a large space, In addition, since it is necessary to return the waste water to the place of departure, it is necessary to equip a tank of a size commensurate with the round trip travel time.

Therefore, the present application provides a separation type vehicular waste treatment device that solves the above-mentioned drawbacks.

Means for Solving the Problems In order to achieve the above-mentioned proposal, the present application provides a toilet provided with a flush water pipe and a flapper valve that opens and closes a discharge port, and a discharge that stores fresh water corresponding to a single usage amount. In order to pressurize the tank and the fresh water supplied into the discharge tank, compressed air is supplied into the discharge tank for a certain period of time for each use, and a first solenoid valve that communicates with the atmosphere after the lapse of that time And a second solenoid valve that discharges the fresh water in the discharge tank in a pressurized state to the wash water pipe for a certain period of time, and the fresh water is supplied to the discharge tank after the second solenoid valve is activated, and the water level in the tank is An electromagnetic water pump that stops the supply when the temperature rises to a certain value, an air cylinder that normally closes the flapper valve, an operating mechanism that activates the air cylinder to open the flapper valve, and a 1 Operate the solenoid valve, And a control means for activating the second solenoid valve and the actuating mechanism after the device is used. Further, in the above, the actuating mechanism is configured to slowly actuate the air cylinder in the closing direction of the flapper valve. It is equipped with an air regulating valve.

Also, in order to give a swirling flow to the water flow discharged from the flush water pipe to enhance the cleaning effect on the inner surface of the toilet bowl, the flush water pipe extends from the front of the toilet bowl to the rear along the plane shape of the toilet bowl and bends at the rear position of the toilet bowl. It is folded back in a circular shape and extends forward, and is formed in a U shape as a whole with one end serving as an inflow end, and a plurality of ejection nozzles are arranged on the lower surface of this washing water pipe at required intervals so that it is rearward from the inflow end. Inclination of the jet nozzle arranged in the extending portion and the inclination of the jet nozzle arranged in the portion extending from the rear to the front opposite thereto are made different so that a swirl flow is generated in the jet flow. Is.

Function However, when the toilet bowl is not in use, the fresh water in the discharge tank is being pressurized by compressed air, and if, for example, the push switch is operated from this state, the solenoid valve and compressed air communicating with the flush water pipe Solenoid valves that supply each of the discharge tanks are opened, and the fresh water in the discharge tank that is under pressure is discharged to the wash water pipe, and the fresh water spouts vigorously to clean the inner surface of the toilet bowl, along with dirt, It is reserved at the outlet of the toilet bowl.

The water level in the discharge tank lowers as the fresh water is discharged to the wash water pipe, and the decrease in the water level is detected electrically, or the amount of one-time use is set by a timer.
