Examples of the disclosure relate to a roof vent blind. The roof vent blind for a recreational vehicle comprising: a cover portion, configured to suspend below a roof vent and at least partially cover the interior footprint of the roof vent; at least one air flow portion. The air flow portion comprises at least one air flow conduit configured to enable air flow between the interior and exterior of the recreational vehicle through the roof vent.

A vent fan and related methods includes a frame surrounding an opening, a lid, and a first fan. The frame includes a cavity, an upper port fluidly connecting the cavity to the opening, and a lower port fluidly connecting the cavity to the opening. The lid is operatively connected to the frame and configured to selectively move from a closed position toward an open position. In the closed position, the lid covers the opening. In the open position, the lid allows an airflow through the opening. The first fan is positioned within the cavity and configured to direct the airflow between the upper port and the lower port for venting the airflow.

An external connection device including a ventilation mechanism and an antenna; the ventilation mechanism includes a housing assembly and a fan arranged inside the housing assembly; wherein the housing assembly is provided with a first through hole and a second through hole, and the fan is connected with a fan cable extending out of the housing assembly from the first through hole; and the antenna is arranged on an outer wall of the housing assembly, and the antenna is connected with the antenna cable, and the antenna cable extends into the housing assembly from the second through hole and extends out of the housing assembly from the first through hole.

A vehicle vent top cover capable of ventilation in a closed position. The top cover includes a top plate having side protection plates extending therefrom. The side protection plates have terminal edges that are offset from the top plate. A duct is contained within the top cover. The duct has an inlet for receiving air from within a vehicle to which it is attached and an outlet that is located between the terminal edges of the terminal edges of the side protection plates and the top plate.

A vehicle roof has a roof opening and a planar, transparent or translucent, roof element which seals the roof opening and is permanently connected to a roof frame of the vehicle roof. A ventilation device is integrated in the roof element and has a ventilation flap. The ventilation flap can be pivoted between a closed position in which the ventilation flap seals a ventilation opening and an open position in which the ventilation flap exposes the ventilation opening. A vehicle is equipped with a vehicle roof of this type.

The present embodiments relate to a roof top air conditioning unit with connection air ducts. The plurality of air connection air ducts are disposed between a roof top unit and an air distribution box. The plurality of connection air ducts define an adjustable height for the air duct that may compensate for vehicles of differing roof thickness dimension.

[Problem] The present invention provides a work vehicle capable of sufficiently securing visibility of a skylight regardless of installation of an air conditioning unit in a cabin.

[Solution] A tractor 1 includes a work vehicle including a cabin 12 having a driver's seat 30 includes: a skylight 52 disposed in a roof portion 42 of the cabin 12; and an air conditioning duct front portion 49b disposed in a front portion of the roof portion 42, wherein a skylight frame 53 opened to the skylight 52 includes a first frame portion 53a provided behind the duct front portion 49b, and a second frame portion 53b continuous from the first frame portion in a region that at least partially overlaps the duct front portion 49b in a front-rear direction and in which the duct front portion 49b is not disposed in a plan view.

A vehicular control system includes a vent structure disposed at a vehicle and having an inlet configured to receive airflow from exterior of the vehicle, an outlet configured to direct airflow into an interior cabin of the vehicle and a conduit extending between the inlet and the outlet. The vent structure is adjustable between a closed state, where airflow is precluded from passing within the conduit between the inlet and the outlet and an opened state, where airflow is allowed to pass within the conduit from the inlet to the outlet and into the interior cabin. An actuator is electrically operable to adjust the vent structure between the closed and opened states. Based on determination that an internal temperature at the interior cabin is greater than an external temperature exterior the vehicle, the system operates the actuator to adjust the vent structure from the closed state to the opened state.

Provided are a ventilator and a vehicle having the ventilator. The ventilator includes a housing assembly, a fan blade, a first drive device, a cover plate assembly, an air guide sleeve, and a controller. The housing assembly has a first accommodation space and a vent. The fan blade and the first drive device are mounted in the first accommodation space. The first drive device is configured to drive the fan blade to rotate about a rotation axis of the fan blade, and is electrically connected to the controller. The cover plate assembly is provided at a side of the housing assembly. The air guide sleeve is provided between the cover plate assembly and the housing assembly and configured to be lifted or lowered relative to the housing assembly to expose or cover the vent. A second accommodation space is defined by the air guide sleeve and the cover plate assembly.
