An onboard washing system provides the ability to wash specific areas at the rear of a concrete truck, without requiring an operator to climb a ladder or climb on the truck. Certain specified areas which are traditionally difficult to wash, including the inside of the charge hopper, the interior portions of the discharge chute, and rear portions of the mixing drum structure, can now be washed in an automated and efficient manner. The truck-mounted washing system has components which are specifically positioned to cause washing fluid (water) to be sprayed or directed toward predetermined areas in an efficient and effective manner. The system also includes hand-held washing wands or washing mechanisms, which allow an operator to easily reach additional zones or additional areas at the rear of the truck, which are lower. Most significantly, the truck-mounted wash systems and the hand-held nozzle systems (wand) are all operable while an operator remains on the ground.

A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends from the inlet valve for cleaning an adjacent area. A pair of seals within the inlet valve retains a nozzle handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on one embodiment of the inlet valves automatically locks the hose in a selected extended position when manually pulled from the inlet valve. A mounting bracket enables the inlet valve to be mounted at various locations in the structure and a pair of seals enables the inlet valve to be open to the ambient atmosphere.

An integrated automobile vacuum system for cleaning a vehicle includes a vacuum motor with an intake side and an exhaust side. A power unit is coupled to the vacuum motor and provides power. An intake pipe is coupled to the intake aperture. A mounting plate is coupled to the intake pipe and is configured to attach to an interior wall of the vehicle. The mounting plate has a hose aperture extending through the interior wall and coupled to the intake pipe. A vacuum hose is selectively engageable with the hose aperture of the mounting plate. An exhaust hose has a motor end coupled to the exhaust aperture and a collection end coupled to a collection unit. The collection unit is configured to collect debris sucked through the vacuum motor.

An in-vehicle system and method are disclosed for identifying changes in the scene inside the cabin of the vehicle before and after usage thereof. The in-vehicle system includes a plurality of sensors that measure, capture, and/or receive data relating to attributes the interior of the cabin. The in-vehicle system includes a scene estimator that determines and/or estimates one or more attributes of the interior of the cabin based on individual sensor signals received from the sensors. The scene estimator determines additional attributes based on combinations of one or more of the attributes determined based on the sensor signals individually. The attributes determined by the scene estimator collectively comprise an estimation of the scene inside the cabin of the vehicle. The scene estimator determines changes in the scene inside the cabin based on changes in the scene estimation before and after usage thereof.

A vehicle includes a radiator including a fan, a driving seat provided on a rear side of the radiator, a dashboard disposed on the rear side of the radiator and on a front side of the driving seat, and a heat shield plate disposed between the radiator and the dashboard. According to this structure, it is possible to prevent a device (for example, an electric component disposed on the dashboard) disposed on the rear side of the radiator from directly contacting air that receives heat of the radiator.

A vehicle has: a communicating portion that communicates a passenger compartment interior with a passenger compartment exterior; a discharging device that, by operating, discharging at least one of dust or liquid which is within the passenger compartment through the communicating portion to the passenger compartment exterior; and a control section that, in a case of judging that there are no vehicle occupants within the passenger compartment, operates the discharging device, and causes dust within the passenger compartment to be discharged to the passenger compartment exterior.
