Abstract

A radiant heater air-conditioning system includes: a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior; an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion; and an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior. The air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set.

First claim

What is claimed is:

1. A radiant heater air-conditioning system comprising:
a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior;
an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion;
an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior;
a specific seat switch operated to set a specific seat mode for performing air-conditioning on a predetermined seat preferentially, the specific seat switch includes a one-seat concentration switch operated by an occupant to set one of a front driver seat, a front passenger seat, and rear seats as the predetermined seat, wherein
the air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set, and
the air-conditioning control apparatus reduces the air-conditioning output to a seat other than the predetermined seat when the energization enable state is set and when the specific seat mode is set, compared with when the energization disable state is set.

2. The radiant heater air-conditioning system according to claim 1 , wherein
the air-conditioning control apparatus reduces an amount of conditioned-air blown into the vehicle interior when the energization enable state is set, compared with when the energization disable state is set.

3. The radiant heater air-conditioning system according to claim 1 , wherein
the air-conditioning control apparatus lowers an outlet temperature of conditioned-air blown into the vehicle interior when the energization enable state is set, compared with when the energization disable state is set.

4. The radiant heater air-conditioning system according to claim 1 , wherein
the air-conditioning control apparatus stops air-conditioning operation when the energization enable state is set.

5. The radiant heater air-conditioning system according to claim 1 , wherein
the air-conditioning control apparatus changes a reduced amount of the air-conditioning output according to an output of the heater main body when the energization enable state is set.

6. The radiant heater air-conditioning system according to claim 1 , further comprising an eco-mode switch operated for setting a power saving mode, wherein
the air-conditioning control apparatus increases a reduced amount of the air-conditioning output when the energization enable state is set and when the power saving mode is set, compared with when the energization enable state is set and when the power saving mode is not set.

7. The radiant heater air-conditioning system according to claim 1 , wherein
the air-conditioning control apparatus reduces the air-conditioning output to a seat toward which the radiant heat from the heater main body is radiated, and does not reduce the air-conditioning output to a seat toward which the radiant heat from the heater main body is not radiated when the energization enable state is set.

8. The radiant heater air-conditioning system according to claim 1 , further comprising an occupant sensor to detect an occupant present in the predetermined seat, wherein
the occupant sensor is different from the one-seat concentration switch operated by the occupant,
the air-conditioning control apparatus determines whether the heating portion is installed in the predetermined seat when the occupant sensor detects the occupant, and
when the heating portion is installed in the predetermined seat, the air-conditioning control apparatus reduces the air-conditioning output to the predetermined seat.

9. A radiant heater air-conditioning system comprising:
a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior;
an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion;
an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior; and
a specific seat switch operated to set a specific seat mode for performing air-conditioning on a predetermined seat preferentially, the specific seat switch includes a one-seat concentration switch operated by an occupant to set one of a front driver seat, a front passenger seat, and rear seats as the predetermined seat, wherein
the air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set, and
the air-conditioning control apparatus reduces the air-conditioning output to the predetermined seat and at least one of seats other than the predetermined seat when the energization enable state is set, when the specific seat mode is set, and when the radiant heat from the heater main body is radiated toward the predetermined seat, compared with when the energization disable state is set.

10. The radiant heater air-conditioning system according to claim 9 , wherein
the air-conditioning control apparatus reduces an amount of conditioned-air blown into the vehicle interior when the energization enable state is set, compared with when the energization disable state is set.

11. The radiant heater air-conditioning system according to claim 9 , wherein
the air-conditioning control apparatus lowers an outlet temperature of conditioned-air blown into the vehicle interior when the energization enable state is set, compared with when the energization disable state is set.

12. The radiant heater air-conditioning system according to claim 9 , wherein
the air-conditioning control apparatus stops air-conditioning operation when the energization enable state is set.

13. The radiant heater air-conditioning system according to claim 9 , wherein
the air-conditioning control apparatus changes a reduced amount of the air-conditioning output according to an output of the heater main body when the energization enable state is set.

14. The radiant heater air-conditioning system according to claim 9 , further comprising an eco-mode switch operated for setting a power saving mode, wherein
the air-conditioning control apparatus increases a reduced amount of the air-conditioning output when the energization enable state is set and when the power saving mode is set, compared with when the energization enable state is set and when the power saving mode is not set.

15. The radiant heater air-conditioning system according to claim 9 , wherein
the air-conditioning control apparatus reduces the air-conditioning output to a seat toward which the radiant heat from the heater main body is radiated, and does not reduce the air-conditioning output to a seat toward which the radiant heat from the heater main body is not radiated when the energization enable state is set.

16. The radiant heater air-conditioning system according to claim 9 , further comprising an occupant sensor to detect an occupant present in the predetermined seat, wherein
the occupant sensor is different from the one-seat concentration switch operated by the occupant,
the air-conditioning control apparatus determines whether the heating portion is installed in the predetermined seat when the occupant sensor detects the occupant, and
