JP2011-105120A

  In such a conventional vehicle air conditioner, when supplying conditioned air to the thigh of the passenger in the passenger seat, a glove box is present in front of the passenger seat, so the main part of the vehicle air conditioner is arranged. It was difficult to extend the exhaust pipe from the center of the vehicle beyond the glove box and supply conditioned air from the outside (door side) of the passenger seat. For this reason, the conditioned air to the passenger's thigh is blown out from the center of the vehicle to both legs of the occupant. It was difficult to provide sufficient heating performance. On the other hand, if the number of air-conditioning air outlets in the dashboard is increased in order to improve the heating performance, the design of the dashboard is degraded.

  The present invention has been made in view of the above circumstances, and its purpose is for a vehicle that has improved heating performance in the thigh of the passenger in the passenger seat without deteriorating the design of the dashboard. It is to provide an air conditioner.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1,
In a vehicle air conditioner that supplies conditioned air to the interior of a vehicle,
The air-conditioning wind outlets disposed on the left and right sides of the front passenger seat are provided adjacent to the lower part of the collar projecting at the boundary between the upper and lower parts of the dashboard.

  According to the above solution, since the air outlets are arranged on the left and right sides of the passenger seat, the conditioned air from the air outlet is appropriately supplied to the left and right thighs of the passenger seat passenger. Moreover, since the blower outlet is arrange | positioned adjacent to the downward direction of a buttocks, it does not appear behind the buttocks from a passenger | crew, and the design property (aesthetics) of a dashboard is not impaired.

  Preferred embodiments based on the above solution are as described in claims 2 and below in the claims. That is, the lower wall surface of the dashboard is disposed obliquely downward, and the conditioned air from the pair of air outlets is blown out toward both sides below the passenger seat. (Claim 2). In this case, since the air outlet opens obliquely downward, the conditioned air from the air outlet is appropriately blown toward the thigh of the passenger on the passenger seat.

  The air conditioning wind discharge pipe is provided at the lower part of the dashboard, and the discharge pipe is a horizontal pipe extending in the left-right direction of the vehicle near the lower end of the glove box disposed at the lower part of the dashboard. And a pair of longitudinal ducts extending upward from the lateral ducts in the vicinity of both left and right ends of the glove box and communicating with the pair of outlets (corresponding to claim 3). In this case, since the conditioned air flows through the horizontal pipe and the vertical pipe before reaching the outlet, a sufficient running distance is given to the conditioned air. Therefore, the conditioned air can be stably adjusted to have an appropriate wind speed and directivity. In addition, since the horizontal pipe line and the vertical pipe line are arranged so as to surround the glove box, it does not obstruct the storage part (opening part) of the glove box and hinder the function of the glove box. Absent.

  ADVANTAGE OF THE INVENTION According to this invention, in a vehicle air conditioner, an air conditioned wind can be appropriately supplied with respect to both thighs of a passenger seat passenger. For this reason, the design of the dashboard is not impaired.
