A disadvantage such as loss of life to a bearing of an indoor fan motor may occur when the number of rotations of the indoor fan falls below a predetermined number of rotations. An indoor unit includes a fan, a casing, a first horizontal flap, a second horizontal flap, and an indoor controller. The casing accommodates the fan, and has a blow-out port through which air provided by the fan is blown out. The indoor controller performs opening and closing operations to bring the first and second horizontal flaps into a first state in decreasing an airflow volume to be blown out through the blow-out port. In the first state, the first horizontal flap is in a position to open a first portion of the blow-out port while the second horizontal flap is in or substantially in a position to close a second portion of the blow-out port.

An axial fan rotates around a rotating shaft. The axial fan includes a hub, and a plurality of blades extending in a radial direction from the hub. Each blade includes a leading edge, a trailing edge including a depression, and a reinforcing protrusion located at least forwardmost and having a wall thickness thicker than a surrounding portion. As viewed along a rotating shaft direction, when a first virtual line and a second virtual line perpendicular to the radial direction are drawn, the reinforcing protrusion extends radially inside of the first virtual line and extends radially outside of the second virtual line, the first virtual line and the second virtual line respectively pass through a rearmost first endpoint in the rotation direction on a radially inside of a rear end that substantially overlaps the depression, and a rearmost second endpoint on a radially outside of the rear end.

When a seat heater and a planar electric heater on a surface of an interior member are used in parallel, the seat heater and the planar electric heater cannot be heated sufficiently due to a limitation on an electric capacity of a vehicle, and in particular, in a vehicle having good engine efficiency, heating of an interior of a passenger compartment by air conditioning utilizing hot air generated by heat expelled from an engine is not sufficient, whereby there sometimes occurs a situation where occupants feel cold. A heating deviceis provided in a side door panelof a vehicle and a seat heater is made to be heated mainly at an initial stage of heating after an occupant gets in the vehicle, whereas the heating deviceis made to be heated after a predetermined period of time elapses, whereby the body of the occupant can be warmed quickly and efficiently without making the occupant feel cold physically.

Vehicle heating system

A seat with a heating device is provided which realizes a configuration in which the arm, palms and finger tips of a user can easily be warmed when the user uses the seat with the heating device. When the user is seated in a seat with a heating device and feels cold due to it being winter, the user controls a switch to heat the seat, whereby energization of heating elementsis started which are connected to a power supply via electric wires. When the energization of the heating elementsis started, heat generated thereby is conducted to skin materialsand surfaces of the skin materials are warmed. When the user places his or her arm on an armrest portion, the arm is warmed via the skin material, whereby the user can feel the sensation of comfortableness.

An apparatus for detecting the flow amount of a fluid passing through a passage. The apparatus comprises a scroll chamber having a circular horizontal cross section and having an inlet opening defined in a tangential direction of the scroll chamber and an outlet opening defined at a substantial center portion of a bottom surface of the scroll chamber. The fluid is introduced through the inlet opening and discharged from the outlet opening. In the scroll chamber, a conically protruding member is provided on a substantial center portion of the top surface of the scroll chamber so as to be protruded vertically and downwardly along the axis of the scroll chamber. A spheral member encased in the scroll chamber is turned about the protruding member and along a wall of the scroll chamber in response to introduction of the fluid through the inlet opening. The flow amount of fluid is measured by detecting the number of turns of the spheral member. The scroll chamber has a conical portion whose diameter decreases toward the upper side and is arranged so that the spheral member is turned with it being brought into contact with the tapered surface of the conical portion. This provides an extremely stable detection of the fluid flow.
