This application is based on Japanese Patent Application No. 2016-177022 filed on September 9, 2016, the description of which is incorporated herein by reference.

This disclosure relates to a heating device.

Conventionally, a heating device that effectively uses waste heat for heating has been proposed. An example of this type of heating device is disclosed in Patent Document 1.

The heating device described in Patent Document 1 is mounted on a vehicle and mainly for warming the feet of passengers. This heating device includes a radiant heater and a blower fan. The radiant heater is fixed on the lower side of the instrument panel while being spaced from the inner wall surface of the vehicle body. The blower fan is disposed in a space between the inner wall surface of the vehicle body and the radiation heater. And this heating apparatus radiates radiant heat (henceforth a 1st radiant heat) toward the passenger | crew's foot from the surface of a radiation heater. At the same time, this heating device radiates radiant heat (hereinafter referred to as second radiant heat) to the back surface of the radiant heater (that is, the space side surface). At this time, the second radiant heat moves from the space to the area where the first radiant heat is radiated (hereinafter referred to as the first heat radiating area), that is, the periphery of the occupant's feet, by the wind from the blower fan. After that, the second radiant heat again enters the area near the blower fan and moves along the same route as before. As described above, the second radiant heat circulates and moves along the route around the radiant heater, and warms the feet of the passengers disposed in the route.

This heating device achieves efficient heating by utilizing the second radiant heat (that is, heat that was originally used as waste heat).

JP 2014-15139 A

However, in the heating device described in Patent Document 1, the second radiant heat merely circulates and moves along a path around the heat radiating portion (that is, the radiant heater). For this reason, in this heating device, although waste heat (that is, second heat) can be utilized to warm a part such as a foot of an occupant disposed in the route, according to the inventors' investigation, Waste heat cannot be used to warm parts (eg, knees and thighs) far away from this path. That is, in this heating device, a part different from the part mainly heated by the heat radiating part cannot be heated by the second heat, and a plurality of parts different by one heat radiating part cannot be heated by the second heat.

This indication aims at providing the heating device which can warm the part different from the part mainly heated by one heat radiation part with the 2nd heat.

According to one aspect of the present disclosure, there is provided a duct that includes an internal space for allowing the wind generated by the wind generating unit to pass therethrough and includes an air outlet for blowing the wind from the internal space to the outside of the internal space. The heating device has. The duct is provided so that heat radiated from the heat radiating portion (that is, heat that was originally used as waste heat and not used) is transmitted to the air in the internal space. Then, the air in the internal space to which the heat is transferred moves in the internal space by the wind and is blown out from the outlet.

According to this heating device, heat that is radiated from the heat radiating section (that is, originally used as waste heat) is utilized by supplying air to be heated that moves in the internal space of the duct and blows out from the air outlet. It is possible to perform heating using the heat that did not exist. That is, in this heating device, a part different from the part to be warmed can be warmed by the second heat, whereby the heating of the predetermined part by the first heat and the different part by the second heat are performed by one heat radiating part. Both heating can be done.

In order to achieve the above object, according to another aspect of the present disclosure, a sealed member that is formed so that a sealed space filled with air is formed and second heat is transmitted to the air in the sealed space. The heating device has. The occupant is warmed by the second heat transmitted to the air in the sealed space.

According to this heating apparatus, the above-mentioned sealed space can be warmed by the second heat, and as a result, a portion of the sealing member located away from the radiating portion can be warmed. Thereby, the to-be-heated object which touches this part can be warmed. That is, in this heating apparatus, a part different from the part to be mainly heated can be warmed by the second heat. Thereby, this heating apparatus can perform both the heating of the predetermined site | part by 1st heat | fever, and the heating of another site | part by 2nd heat | fever with one heat radiating part.
