Description
【発明の詳細な説明】 本発明は自動車の暖房装置に関するものである。[Detailed description of the invention] The present invention relates to a heating device for a vehicle.

に設けられた吹出口より前席乗員の足元に吹き出すよう
になっているのが普通である。Generally, a heating system for an automobile is equipped with a heater core that uses engine cooling water in a duct installed in the instrument panel, and hot air that is heated while passing through the heater core is passed through an outlet provided at the bottom of the instrument panel. It is normal for the air to blow out at the feet of the front seat occupants.
このような一般的な暖房装置において、後部座席の乗員
の暖房を効果的に行う為に前席後部附近に、ヒータコア

ものが開発されている。Among such general heating devices, one has been developed in which a second heater unit including a heater core, a fan, etc. is mounted near the rear of the front seat in order to effectively heat the occupants in the rear seats.

である。In the conventional device provided with the second heater unit for the rear seats, as shown in FIG. On the other hand, since the second heater unit B consisting of a heater core 11 and a fan 12 through which the engine cooling water that has passed through the heater core 1 of the first heater unit A flows is provided near the rear of the front seat, the second heater unit L- The air sucked into B is indoor circulating air, and the warm air blown out from the first heater unit A is released into the vehicle interior and circulated, and the air whose temperature has dropped to a certain degree is sucked into the second heater unit B. Therefore, the second heater unit B
The temperature of the air blown out from the air outlet 13 does not become very high, so the limited amount of heat cannot be used efficiently, and overall the heating effect for the occupants cannot be said to be very good. , especially when the outside temperature is between -25°C and -35°C.
It is completely unsuitable as a heating system in extremely cold regions where temperatures can reach even lower temperatures.
本発明は限られた熱量にて極寒冷地にも充分適応できる
暖房効果を得ることができる暖房装置を提供するもので
ある。The present invention provides a heating device that can obtain a heating effect that is sufficiently applicable to extremely cold regions with a limited amount of heat.

一ヒータユニットＡより吹き出した温風の大部分が直接
第二ヒータユニットＢに吸い込まれ、そのヒータコア１
１により更に効率良く加温されて吹出口１３より車室内
後方に向って吹き出されるようにしたものである。That is, in the present invention, as shown in FIG. 1, by providing the suction port 14 of the second heater unit B near the hot air outlet 3 of the first heater unit A provided in the instrument panel, Most of the warm air blown out from unit A is directly sucked into second heater unit B, and its heater core 1
1, the air is heated more efficiently and is blown out from the air outlet 13 toward the rear of the vehicle interior.
尚第１図示の実施例では、第一ヒータユニットＡの吹出

トＡの吹出口３近傍に対向させて設けるだけでも良い。The embodiment shown in the first figure shows an example in which the air outlet 3 of the first heater unit A and the suction port 14 of the second heater unit B are connected by a perforated duct C having a large number of holes. ,
By doing this, most of the hot air blown out from the first heater unit A can be sucked into the second heater unit B, but the perforated duct C is omitted and the hot air is simply sucked into the second heater unit B. It is also sufficient to simply provide the opening 14 in the vicinity of the air outlet 3 of the first heater unit A so as to face it.

る。According to the present invention configured in this manner, the temperature of the air sucked into the second heater unit B is high, and the temperature of the engine cooling water flowing through the heater core 11 portion of the second heater unit B decreases little, so that the engine D The temperature of the water supplied to the first part of the heater core of the first heater unit A increases, and the heating fraction increases, and the temperature of the air blown out from the second heater unit B increases considerably, causing extremely cold temperatures. Even on the ground, the high-temperature blown air directly hits the feet of the occupants, providing an effective heating function.
