Radiant heating device for vehicle
A radiant heating device for a vehicle includes a radiant heater that radiates radiant heat toward a passenger and is provided together with an air-conditioner that selectively introduces air outside a passenger compartment or air inside the passenger compartment and then supplies conditioned air generated from the introduced air into the passenger compartment. The radiant heating device includes a controller that differentiates a radiant energy amount of the radiant heater when the introduced air into the air-conditioner is the air outside the passenger compartment from when the introduced air is the air inside the passenger compartment. According to the radiant heating device, the passenger can be provided with warm comfort feeling both in an outside air intake mode and in an inside air intake mode of the air-conditioner.
1. A radiant heating device for a vehicle, comprising:
a radiant heater that is provided together with an air-conditioner and radiates radiant heat toward a passenger, the air-conditioner selectively introducing air outside a passenger compartment or air inside the passenger compartment and then supplying conditioned air generated from the introduced air into the passenger compartment,
wherein the radiant heating device includes a controller that controls a radiant energy amount of the radiant heater by differentiating between when the introduced air into the air-conditioner is the air outside the passenger compartment and when the introduced air is the air inside the passenger compartment.
2. The radiant heating device according to claim 1 , wherein
the radiant heater includes a plurality of heating sections that radiate heat toward regions of the passenger, respectively.
3. The radiant heating device according to claim 2 , wherein
the controller adjusts radiant energy amounts of the plurality of heating sections based on when the introduced air into the air-conditioner is the air outside the passenger compartment and when the introduced air is the air inside the passenger compartment.
4. The radiant heating device according to claim 3 , wherein
one of the plurality of heating sections radiates radiant heat toward knees of the passenger.
5. The radiant heating device according to claim 3 , wherein
one of the plurality of heating sections radiates radiant heat toward calves of the passenger.
6. The radiant heating device according to claim 3 , wherein
one of the plurality of heating sections radiates radiant heat toward thighs of the passenger.
7. The radiant heating device according to claim 3 , wherein
the plurality of heating sections radiate radiant heat toward thighs, knees, shins, toes, calves, heels, a thigh-sideface and an ankle-sideface of the passenger, respectively.
8. The radiant heating device according to claim 1 , wherein
the radiant heater radiates radiant heat toward the passenger on a rear seat.
9. The radiant heating device according to claim 1 , further comprising an operational panel for operating the radiant heater.
10. The radiant heating device according to claim 9 , wherein
the operational panel includes an adjustment switch configured to adjust a radiant energy amount of the radiant heater.
11. The radiant heating device according to claim 9 , wherein
the operational panel includes a switch configured to set a radiant energy amount of the radiant heater to a maximum amount.
12. The radiant heating device according to claim 1 , wherein
the air-conditioner is configured to perform a normal heating operation and an economical heating operation, and
the controller, in the economical heating operation, operates the radiant heater when a passenger is seated on a rear seat, and does not operate the radiant heater when a rear seat is unoccupied.
13. The radiant heating device according claim 2 , wherein
the controller controls a radiant energy amount of the radiant heater by a pulse width modulation control.
14. The radiant heating device according to claim 2 , wherein
the radiant heater includes a plurality of electric heating wires having different patterns, and
the controller adjusts a radiant energy amount of the radiant heater by changing over energization to the electric heating wires.
15. A radiant heating device for a vehicle, comprising:
a radiant heater configured to provide radiant heat toward a passenger, and
a controller configured to control a radiant energy amount emitted from the radiant heater, the controller configured to receive an input signal differentiating between a first air intake mode where air is introduced into a passenger compartment from outside the passenger compartment and a second air intake mode where the air is from inside the passenger compartment,
wherein the controller is configured to adjust the radiant energy amount emitted from the radiant heater differently according to the input signal representing the first air intake mode or the second air intake mode.
