The outlet of conventional air conditioners is 1:1) with a louver installed at the open end of the air tact to change the direction of the air (lid IB1/J).
The structure has an air outlet J, and a blower J that blows air! lil iJ.
It shows a flow velocity distribution of 4f, the degree of diffusion is constant, and the amount of air blown to the occupants is not sufficient at the beginning of the amount of air blown. In this step, the air flow rate and direction are changed, but changing the air flow rate changes the temperature distribution inside the vehicle')'f! There is also a limit to the temperature fluctuations and the ability to change the wind direction.

By the way, constant J'f, 1. When a free jet of H is sent into a stationary fluid, the lower the flow velocity at the outer circumferential portion of the jet in contact with the stationary fluid, the smaller the viscous horns etc. that occur between each stationary flow, and the diffusion attenuation of one free jet is prevented.

Therefore, the patent applicant paid attention to the above relationship and
A sub-fluid passage is formed on the outer periphery of the inner wall, and the flow velocity of the sub-fluid passage is made lower than that of the fluid passage. It is possible to extend the temperature range and give the user a sufficient amount of power! IH Application 11] 57-230937.

As a result of the damper plates 71Δ, 71B, 72A, and 728h rotating in mutually symmetrical directions, the opening on the second side of the main fluid passage 4 is expanded or narrowed in the direction ()-C toward the windward side.

Damper plate 71A, 7113.72A, ? 213 is shown in Figure 7'TJJ, 71A, 7H"3 is on the tamper
The tamper plates 71A and 7113 are attached (=Jt) to the hinge shaft 71a.
As shown in Figure 9, the upper sub-fluid passage 1fj51J3 and the left
The area of the holes 53 and 54 in the secondary stream 1 is changed to adjust the flow rate of the blowout flow through the main fluid passage 4.

The operation of this embodiment will be explained based on FIGS. 8 to 16.

b) In the case of Figure 8.9, by passing through the grid 6, a uniform flow velocity V is generated at the outlet 1.
The airflow t that has reached this point is divided into a main fluid and a subfluid by partition plates 31, 32, 33, and 34. Here, the flow velocity of the blowout flow passing through the subcontractor fluid passage 51.52J> and the left and right sub-fluid passages 53.54, and the flow velocity of the Suita flow passing through the main fluid passage 4 are adjusted so that they are equal to each other. Ru. The main fluid is squeezed into the main fluid passage 4 through the widened inlet and accelerated, while the auxiliary fluid, on the other hand, passes through the narrowed inlet and is decelerated as the passage becomes wider. As a result, as shown in FIG. 12, the flow velocity distribution of the main fluid and the auxiliary fluid becomes VO7/Vi<1.

In the case of Figure 10.11, the main fluid is decelerated and the secondary fluid is accelerated to J as shown in Figure 13.
Therefore, the flow velocity distribution becomes VO/Vi > 1.

C) The ratio of the passage width of Suita Exit 1 to/t: 0.3
~0.7, the flow velocity distribution V in the state shown in Fig. 12.

/Vi is set to 0.3 to 0.6, and in the state shown in Fig. 13, the flow velocity distribution VO/Vi is set to 1.2 to 1.6, and for each case, the distance is 70 cm1 from the air outlet 1! [We measured the distribution of the temperature attainment rate within the vertical plane at the point where the air outlet was exposed and compared it with that of a conventional outlet. This is shown in Figures 14 and 15, respectively. In Fig. J3, the line x indicates the air outlet [''1] of this embodiment, and the line y indicates the conventional air outlet.

According to FIG. 14, when air is blown into an almost stationary atmosphere, the blown air is divided into a main fluid flowing through the center 814 and a sub-fluid flowing outside the main fluid.
In No. 1, by reducing the flow velocity of the secondary fluid and suppressing the viscous force between it and the stationary atmosphere, diffusion attenuation of the air blast is prevented, the drying up at - is maintained, and the reach distance is extended. −
1) If the flow velocity of the secondary fluid is reduced to actively create a viscous horn with the stationary atmosphere, as shown in Figure 15,
A blowout spreads rapidly and spreads evenly.

The damper machine 4i47 of the main fluid passage 4 and the sub-fluid passages 51, 52, 53, 54 can change the flow velocity distribution of the main fluid and the sub-fluid even in the left-right direction, thereby eliminating the entrainment of surrounding fluid from the left-right direction. It is possible to calculate the temperature attainment rate.

Figure 16 shows the state of Figure 12 with the balloons 1" 1J, 7
J-0 (1) shows the temperature attainment rate measured at a distance of 0 cm. J-0 (1) is the one in which the aperture 1 is changed only at the top and bottom.
(2) is a change in the upper and lower J7 J: and left and right [11 odor combinations]. The mixed reach rate is higher than conventional (3).

d3,) The quality attainment rate is expressed by the following formula.

Ambient temperature 1 Good - Temperature attainment rate of measurement point - Ambient temperature 1 Poor - Outlet L 2 7:150111/h.

The present embodiment is characterized in that two dampers are used to simultaneously adjust the flow velocity distribution of the main stream and the sub-fluid not only in the upper and lower directions, but also in the left and right sides, thereby increasing the temperature attainment rate.

In this embodiment, although it is not necessarily necessary to widen the -1 end of the air outlet 1, it is necessary to widen it at an angle of 20 mm or less.
It is more effective to tighten it.

In addition, the turbulence in the airflow caused by the bending of the air ducts 1 to 11, the II3, and the chamber plates 71A, 171B, 72A, and 72B is rectified by the grid 6 as in the first embodiment, so the above effect is even greater. Become.

Note that the following means may be used in addition to the above embodiments.

(1) In the above-mentioned embodiment, the lattice is made by hardening the aluminum honeycomb part to the resin frame with an adhesive or the like, but the honeycomb part and the frame may be formed by molding the resin body.

(2) The above-mentioned damper mechanism can be manually operated using a combination of a link mechanism and a controller to roll cable (one side may be used).

(3) The damper is driven by a servo motor, a DAI A7 flam actuator, etc., and the servo Tanabata
The operation of drive devices such as die '17 flam actuators can be automatically controlled by a control circuit that detects air temperature and operates, or by a timer circuit that outputs an output for a certain period of time after one movement. 'IJruJ, if you get it,
It is possible to automatically control the operation of the tapper.

(4) A tamper (imaginary) can be installed in the middle of the main fluid passage Jj and the sub-fluid passage in addition to the upstream side 1 of the main fluid passage. In this case, a variable throttle member instead of a tamper can be installed between Installed on one or both sides of the aisle.

(5) Set the pendeletion outlet to the above-mentioned outlet pressure 1.
By adopting a structure in which the flow rate can be varied and applying the drive device and control circuit described in (3) above, the blowing air at each outlet can be controlled independently.

(6) The lattice has a plurality of partitions parallel to each other in the longitudinal direction, J3 and/or horizontal direction of the honeycomb shape, and the air outlet LTI is limited to the honeycomb shape. If the lattice frame is formed in a cylindrical shape, the frame of the lattice is formed in a cylindrical shape, and in that case, a plurality of concentric partitions are provided inside the cylindrical frame. Gratings are not limited to Suita air conditioners for automobiles, but can also be used to ventilate localized areas of large spaces such as factories, and are also used at the outlet of air conditioners. It is possible to achieve fruitful effects.

(8) Tamper plates 71Δ and 72A, J3J, and tamper plate 7
1B and 7213 are installed separately so that they can be operated independently.
