초록 ▼

A vehicle dryer includes an energy-conserving rotatable inlet butterfly valve to selectively admit or block air to a fan encased in a blower housing. The valve includes a plate mounted on a shaft that extends across the inlet portion of the blower housing. The plate is rotated by its shaft to either an opened position for admitting air into a blower housing, or a closed position for blocking air from entering into the blower housing. A crank arm is coupled to the valve shaft, and a pneumatic cylinder includes a piston rod for turning the crank arm through a ninety-degree angle, thereby rotating the valve plate between its opened and closed positions.

1. A vehicle dryer for directing a stream of air at a vehicle proximate thereto, said vehicle dryer comprising in combination: a. a motor;b. a fan coupled to the motor for being rotated thereby about a first axis of rotation, the fan being adapted to discharge air therefrom;c. a housing surrounding the fan, the housing having an entrance opening adapted to admit air to the fan, the housing receiving air discharged from the fan and including an outlet nozzle for expelling air discharged by the fan;d. an inlet passageway for guiding incoming air into the entrance opening of the housing;e. a valve rotatably mounted within the inlet passageway, the valve having an open position for allowing air to pass through the inlet passageway into the fan, and the valve having a closed position for substantially blocking air from passing through the inlet passageway; ande. an actuator coupled to the valve for rotating the valve to its open position when a vehicle is proximate to the vehicle dryer, and rotating the valve to its closed position when a vehicle is not proximate to the vehicle dryer. 2. The vehicle dryer of claim 1 wherein said valve includes a generally circular disc mounted upon a rotatable shaft. 3. The vehicle dryer of claim 1 wherein the inlet passageway is generally circular in cross section, and wherein said valve includes a circular plate coupled to a rotatable valve shaft, the circular plate having an outer diameter commensurate with the generally circular cross section of the inlet passageway. 4. The vehicle dryer of claim 3 wherein the rotatable valve shaft extending along a second axis of rotation, the second axis of rotation lying substantially perpendicular to said first axis of rotation. 5. The vehicle dryer of claim 4 wherein the first axis of rotation and the second axis of rotation are substantially co-planar. 6. The vehicle dryer of claim 5 wherein the first axis of rotation passes substantially through the center of the circular plate. 7. The vehicle dryer of claim 3 wherein: a. the housing includes a front wall;b. the entrance opening of the housing includes an aperture in the front wall of the housing; andc. the inlet passageway is an inlet cone extending into the housing through the entrance opening thereof. 8. The vehicle dryer of claim 3 wherein: a. the housing includes a front wall;b. the entrance opening of the housing includes an aperture in the front wall of the housing; andc. the inlet passageway and the valve are disposed ahead of the front wall of the housing communicating with the entrance opening of the housing. 9. A method of efficiently operating a vehicle dryer, said method comprising the steps of: a. supporting a fan for rotation within a housing, the housing including a central inlet for supplying air to the fan and a discharge outlet for discharging air from the fan;b. rotating the fan with a motor;c. mounting a valve for rotation within the central inlet of the housing;d. rotating the valve to an open position when a vehicle is proximate to the discharge outlet for allowing air to be supplied to the fan; ande. rotating the valve to a closed position when a vehicle is not proximate to the discharge outlet for substantially blocking the passage of air to the fan; whereby the motor requires less energy to rotate the fan when the valve is rotated to its closed position. 10. The method of claim 9 wherein the step of rotating the fan includes rotating the fan about a first axis of rotation, the step of mounting the valve includes the step of mounting the valve for rotation about a second axis of rotation, and wherein the second axis of rotation is substantially perpendicular to the first axis of rotation. 11. The method of claim 9 wherein the step of rotating the valve to the closed position includes the step of rotating the valve approximately ninety degrees from its open position.
