Abstract

PURPOSE:To obtain comfortable air conditioning operation by opening or closing an opening/closing door provided in a duct passage that is led to knee-position outlet or a foot-position outlet of an air conditioning unit by means of configuration storing material which varies its configuration in correspondence to the temperature of wind that has passed through a heater core. CONSTITUTION:When an engine is just started and a blower starts turning in low outdoor temperature like in winter, since the temperature of wind sent into a duct 1e through a heater core 3 is lower than the specified temperature, a coil- shaped configuration storing material 7 remains shrunk. Thus, a door 6 is kept closed via arms 11 and 9 etc., preventing cold wind from coming into the car room from a knee-position outlet 1C or a foot-position outlet 1d. When the heater core 3 warms up sufficiently and the wind temperature reaches the specified one, the configuration storing member 7 expands, and the door 6 is opened by means of the arms 11 and 9 etc., allowing warm wind to come out of the outlets 1c and 1d.

Description

[Detailed description of the invention]

The present invention is an automobile σ)′q! This relates to a gas phase device. As shown in the fi1 diagram, as an air conditioner for a car,
-4 [Ventilation duct having a K intake port 1a and a ventilation outlet 1fiJP knee outlet 1c or foot outlet LD on the other end side] 1 and the ventilation duct l are arranged at the intake 01a+Akebono. It is installed in the duct 1 in 1st grade 4 with a proa 2 that introduces outside air (!l) into the duct 1, and a cold air bypass passage 36 in the flow of the proa 2 and the connecting part. The heater core 3 is equipped with an air mix door 4 that opens and closes the heater core 3, and when the heater core 3 is closed with the air mix door 4! The wind introduced by Proa 2 bypasses the heater core 3 and flows, and when the air mix door 4v is opened, the warm air generated by the heater core 3vJIM and the breeze 1 that bypasses the heater core 3 are sent to the air ox. The cold air passes through the chamber 5 and blows out from the ventilation outlet II) of the duct 1, and the air flows through the outlet 1c and the foot outlet 1.
The so-called cold foot heat type, which starts blowing from the beginning, is widely used. However, all like this! Even with the air conditioning knee 1, when the outside air is low, such as in winter, even if you sit on the car, start the engine, and turn the blower 2V, the air outlet 1 (4
) Mother-in-law outlet 1. 1 sip blows out from i [The drawback was that the cold air blew out, temporarily making my feet feel cold, which made me feel even colder and more uncomfortable. If this is the case, it will take a certain amount of time for the heater core 3 to warm up, and until then, the outside air will be blown out from the knee outlet IC and the foot outlet LD without adjusting the temperature even though the heater core 54ta1j4 is in use. It is. The present invention eliminates the conventional drawback V'%S mentioned above, and when the heater core has not warmed up yet and therefore the outside air that has flooded the nuclear heater core is colder than a predetermined temperature, the ventilation duct is closed and the cold air is 1
It prevents air from blowing out from the main air outlet and foot air outlet O, and the heater core

[If you get confused and the outside air that blows into the heater core becomes more than stannic acid, open the 1 city wind duct and let the r crystal wind blow out from the skin blowout outlet. It was made for the purpose of supplying the air 1 supply # to the air σ), and its main structure is as shown in the figure riil'i below Figure 2. 1dvC1t@jiruduct IP11role,
A door 6 for opening and closing the duct passage 18 is provided, and the door 6 is operated to open and close by changing the shape of the heater core 3 depending on the degree of the wind. In the first waste embodiment shown in Figs. is fixed, and when the d-arm 9i is rotated by a predetermined angle in the diagonal direction, the door 6 is also rotated by a predetermined angle, and the upper and lower ends 6a and 6b of the vaginal door 6 are connected to the duct. 4 roads 1elσ) above.

Projections 11 provided on the inner peripheral surfaces of Ig and lh. lj and closes the duct passage 1ev (see Figure B in Figure 3).Also, when arm 9v is rotated clockwise by a predetermined v angle If, the duct passage 1ev is closed.
Then, the door 64 rotates at a predetermined angle, and the door 6 rotates through the duct.
The passage 1llK is parallel to the passage 1e to open the passage 18 (see driving diagram). In addition, the shape memory material 7 is made of publicly available shape memory alloys such as Nokeru titanium alloy or steel-zinc-aluminum alloy (IIfi), and is formed into a coil shape that stretches when it exceeds a predetermined temperature and returns to its original shape when the temperature drops below a predetermined temperature. , so ctr -4 cars huff'

Since the air-conditioning lid of the first embodiment has the above-mentioned U-opening configuration, even in winter when the outside temperature is low, even if you get in the car and start the engine and turn the blower 2V, the taco core 3 will warm up.
The door 6 is made of shape memory material 7 and the arm 1 until the air sent to AMle through the core 3v exceeds a predetermined temperature ltY.
