本発明は温冷風を混合し吹出し温度をコントロールする
エアミックスタイプの自動車用空調装置Iこおいて、特
に温冷風の混合性改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air mix type automotive air conditioner I that mixes hot and cold air and controls the blowout temperature, and particularly relates to improving the mixing properties of hot and cold air.

ス路7を通過してヒータコア6を通過しないため冷気の
まま車室内へ吐出される。A conventionally known air conditioner of this kind is constructed as shown in FIG. 1, and includes a heater core 6 and a damper 8 for controlling the blowing temperature by changing the mixing ratio of hot and cold air. When the damper 8 is at the dashed line position, all of the inflowing cold air passes through the heater core 6 whose heat source is the car's engine cooling water and is heated to become high-temperature warm air; Since the cold air passes through the bypass path 7 and does not pass through the heater core 6, the cold air is discharged into the vehicle interior as it is.
また、適当な中間位置たとえば1点鎖線位置(こダンパ
8を設定することlこより、温冷気は下流の混合室9に
て混合され好みの温度となる。In addition, by setting the damper 8 at an appropriate intermediate position, such as the position shown by the dashed-dotted line, hot and cold air is mixed in the downstream mixing chamber 9 to reach a desired temperature.

好みの温度に調節された温冷気が車室内に吹出される。A ventilation passage 12 and an upper air outlet 13 are provided downstream of the mixing chamber 9 to a defroster air outlet 10 and a lower air outlet 11, and an air outlet mode switching lever (not shown) on the air conditioning control panel of the instrument panel inside the vehicle is provided. damper 14 by operating
The ventilation passage 12 and the upper air outlet 13 are selectively opened and closed,
Hot and cold air adjusted to the desired temperature is blown into the passenger compartment.

適度(こ低くすることが必要である。Here, in order to provide comfort for the occupants, if there is only one outlet, it is necessary to mix hot air and cold air sufficiently, but in pie level mode, which blows from both the upper and lower outlets. Alternatively, in a differential heating mode in which air is discharged from both the defroster outlet and the lower outlet, the temperature of the upper outlet or the defroster outlet needs to be moderately lower than the temperature of the lower outlet.

って車室内へ吹出されるため、著しく温度差がつき乗員
に不快感を与えるという欠点をも−っていた。However, in the conventional configuration, the size of the mixing chamber 9 is often not large enough due to the space constraints of the automobile, and in such cases (here, the damper 14 is moved from an intermediate position, that is, from both the top and bottom). When used in the blowout spy level mode or the differential heating mode, the cold air from the bypass passage 7 is scooped up by the damper 14t as shown by the arrow in the figure, and flows only toward the upper outlet 13, so that the hot and cold air is mixed properly. Since the air is blown into the vehicle interior in two layers without being heated, there is a disadvantage that a significant difference in temperature occurs, causing discomfort to the occupants.
またダンパ14を切換え作動させるとき、このダンパが
風圧を受けるため、吹出モード切換えレバーの操作力が
著しく重くなるという不具合がある。Further, when the damper 14 is switched and operated, this damper is subjected to wind pressure, so there is a problem that the operating force of the blowout mode switching lever becomes extremely heavy.

目的とする。The present invention has been made in view of the above points, and the damper for switching the air outlet is changed from the conventional flat plate shape to a special shape having an arcuate outer peripheral surface, and the air outlet is placed on the side of the cold air bypass path. By arranging the upper air outlet, the defroster air outlet, and the lower air outlet in this order, the interior of the damper becomes a mixing chamber to ensure sufficient mixing of hot and cold air, and when the air is at pie level or when the defroster is - It is an object of the present invention to provide an air conditioner for an automobile that can provide an appropriate difference in upper and lower temperatures when used in combination with footwell heating, and can significantly reduce damper operating force.

足熱の快適な温度分布が得られる。As can be understood from the above table, in the pie level (one foot outlet and one upper outlet) mode, the damper 14 is operated at the dashed-dotted line position (and the damper 15 is operated at the solid line position), and the lower outlet 11 and upper outlet are operated. Both outlets 13 are opened at the same time, while in the defroster foot outlet combination mode, the damper 14 is operated to the dashed line position and the damper 15 is operated to the dashed line position f, so that both the defroster outlet 10 and the lower outlet 11 are operated at the same time. However, in that case, in pie level (one foot outlet and one upper outlet) mode, the upper outlet 1
3, and in the combination defroster and footwell mode, the defroster outlet 10 is located and opened at the cold air side of the mixing chamber 9 and the ventilation passage 12 (where there is more cold air). Even if 14 is operated to the intermediate position, the airflow is divided into two layers of cold and hot air. Therefore, the temperature of the air blown from the upper outlet 13 or the defroster outlet 10 is the same as that of the other outlet in each mode. The temperature is moderately lower than the temperature of the air blown from the outlet, and both modes provide a comfortable temperature distribution that keeps your head cold and your feet warm.

It is of the three-layer flow (cold air-warm air-cold air) type, and is otherwise the same as the first embodiment, and has the same effects as the first embodiment.

温度分布が得られるという効果が犬である。As described above, according to the present invention, when air is simultaneously blown into the vehicle interior from the upper and lower two types of air outlets, such as in the pie level mode or the defroster/footwell blowing combination mode, the temperature of the upper and lower blown air can be adjusted to an appropriate temperature. Dogs have the distinct advantage of providing a comfortable temperature distribution with cold heads and warm feet.

度を低くして、快適な温度分布が得られる。Further, when the damper 14 is operated to the intermediate position, the lower air outlet 11 is closed from the damper 15i, and a defroster/upward air outlet combination mode is adopted in which air is blown simultaneously from the upper air outlet 13 and the defroster air outlet 10. Also, a comfortable temperature distribution can be obtained by lowering the temperature of the upwardly blown air compared to the defroster blown air temperature.
また、ダンパ14による冷風のすくい上げがないので、
吹出空気温度を低温から高温まで直線的に良好に制御で
きる。Also, since there is no scooping up of cold air by the damper 14,
The temperature of the blown air can be well controlled linearly from low to high temperatures.

て、大幅に軽減できるという効果がある。Furthermore, since the damper 14 has a structure in which the air flow path is switched at its arcuate outer circumferential surface 14b, the rotational operating force of the damper 14 can be significantly reduced by eliminating the influence of moment action caused by wind pressure t. There is an effect.

る。In addition, Japanese Patent Publication No. 51-40335 has proposed a device that uses a cylindrical damper to switch the air outlet, but this conventional device has the disadvantage that the weight of the damper itself is heavy. , since the frictional resistance with the casing side increases, there is a problem that the damper operating force increases.
In addition, since the direction of the blowing air is changed by 90 degrees inside the cylindrical damper, ventilation resistance increases, and the installation of the cylindrical damper inevitably increases the overall shape of the heater unit, making it difficult to install it inside the vehicle. However, according to the special damper structure of the present invention, since the sliding area with the casing side is small, the frictional resistance is small and the damper operating force can be reduced. Since the airflow can flow smoothly, the ventilation resistance is small, and furthermore, the shape of the damper is small, so the overall shape of the heater unit can be made compact.
従って、前記公報記載の従来装置に比して種種の観点で
優れた効果が得られる。Therefore, superior effects can be obtained from various viewpoints compared to the conventional apparatus described in the above-mentioned publication.
