<background-art><p>The present invention relates to a cooling and heating tuyere formed on an instrument panel of a vehicle, and more particularly, a tuyere of a vehicle configured to be used by selectively withdrawing from the instrument panel so that a passenger can freely send cold or warm air to a desired place. is about</p><p>BACKGROUND ART In general, a ventilation device for drawing in fresh air from outside air and circulating the inside air is provided in automobiles in order to create a comfortable indoor space. There are two types of ventilation devices: a natural method that draws in outside air generated while the vehicle is driving, and an electric type that forcibly sends air into the room using an electric fan. In particular, it is configured to share a cooling device and a heating device together, and is configured to maintain a constant indoor temperature in the interior of the vehicle.</p><p>On the other hand, the cooling and heating device is configured to be directed from the central duct ventilation port to the indoor central outlet of the instrument panel, and the outside air generated during running is introduced into the room by connecting the duct formed on the dash panel to the central outlet of the instrument panel. configured to be</p><p>In addition, a blower that can selectively control the blowing direction from the outlet is connected to an end of the outlet formed on the instrument panel. When the coupling structure of such a tuyere is described with reference to the drawings, a housing 10 of a certain size is formed inside the instrument panel, is inserted into the housing 10 and rotates up and down, and the wind vane inside the housing 10 A case 20 in which 21 is integrally connected in the transverse direction at equal intervals, and a plurality of directional blades 22 are vertically connected to the wind direction blades 21 in the case 20 to be easily rotated left and right Formed so that the blowing direction can be adjusted up and down, left and right.</p></background-art><tech><p>However, the blower formed on the instrument panel as described above has a wind direction angle at which the wind direction can be adjusted, as well known, changes according to the up and down movement of the case and the left and rear rotation angles of the directional wing, so the blow angle is limited only in a very limited direction. Since this is adjusted, there is a problem in that the wind direction cannot be sent to the part desired by the occupant.</p><p>The present invention has been devised to solve the problems of the related art as described above, and it is intended to provide a tuyere for an automobile configured so that the occupant can locally send the wind direction to a desired part by freely adjusting the wind direction angle blown from the outlet to a desired angle. There is a purpose.</p><p>In order to achieve the above object, the present invention provides a housing of a certain size is formed on the inside of an instrument panel, is inserted and interposed in the housing, and rotates up and down, and the wind direction blades are connected to the inside at equal intervals in the transverse direction. In the case and a tuyere of an automobile in which a plurality of directional blades are connected to be easily rotated left and right vertically in the case, a longitudinal guide groove is cut and formed in a housing of the instrument panel to face; An elastic hook is connected to the outer circumferential surface of the case of the tuyere, and a bellows duct that has a certain length and diameter and is folded back and forth and left and right in the longitudinal direction is connected, and at the end thereof, a moving shaft that is interposed in the guide groove and slides is integrally connected. and a fixing cover having a fixing groove formed on the inner surface thereof so that the elastic hook of the case can be selectively inserted and removed to be easily installed and rotated at the entrance of the housing, It is characterized in that a coil spring is inserted and interposed inside the housing so that the moving shaft slides elastically.</p></tech>

<p>Hereinafter, specific configurations of the present invention and actions thereof will be described in detail with reference to the accompanying drawings.</p><p>Figure 2 is an exploded and assembled perspective view showing the configuration of the retractable tuyere according to the present invention, Figure 3 is an operational state diagram of the retractable tuyere according to the present invention, in the same figure, the same reference numerals as the components shown in Figure 1 to give</p><p>As shown in this figure, a housing 10 of a certain size is formed on the inside of the instrument panel 8, and it is inserted and interposed in the housing 10 and rotates up and down, and the wind direction blade 21 inside the housing 10, etc. In the case 20 connected in the transverse direction of the gap, and in the case 20, a plurality of directional blades 22 are vertically connected to the wind direction blade 21 in the case 20 to be easily rotated left and right. In the housing 10 of the instrument panel 8, a guide groove 12 in the longitudinal direction is cut to be oppositely formed, and an elastic hook 20a is formed on the outer peripheral surface of the case 20 of the air outlet, and a predetermined length and diameter are provided at the rear. and connects the bellows duct 30 that is folded back and forth, left and right in the longitudinal direction, and at the end thereof, a moving shaft 35 that is interposed in the guide groove 12 and slides is integrally connected and formed, The elastic hook 20a of the case 20 selectively installs a fixing cover 40 having a fixing groove 41 formed on its inner surface to be rotated at the entrance of the housing 10 for easy insertion and removal, and the moving shaft The coil spring 50 is inserted and interposed inside the housing 10 so that the 35 is elastically slid.</p><p>On the other hand, it is pointed out that the bellows duct 30 can be configured in a multi-stage storage type that can selectively adjust its length. </p><p>The operation of the present invention configured as described above will be described in detail as follows.</p><p>Referring to the drawings, a moving shaft 35 in which the coil spring 50 and the bellows duct 30 are connected is inserted in the instrument panel 8 housing 10, and the housing 10 entrance has a fixed cover ( 40) is press-fitted to the fixed shaft 11 and fastened. The retractable tuyere constructed in this way, as in the case of using the conventional tuyere, the up and down directions are controlled by the fixed cover 40, and the left and right directions are controlled by the adjuster 22a of the directional wing 22 formed inside the air outlet. Adjust and use.</p><p>On the other hand, when you want to blow air to a local area, when the elastic hooks 20a formed on both ends of the case 20 of the air outlet are pressed, the bellows duct 30 and the moving shaft 25 formed integrally with the air outlet are formed in the housing 10 ) is elastically drawn out and fixed on the guide groove 12 by the coil spring 50 in it. At this time, the bellows duct 30 is configured to flow freely and sends cold air or warmth by matching the tuyere to a desired part.</p><p>In addition, when not in use, when the folded bellows duct 30 is simply pushed into the housing 10 in an unfolded state, the elastic hook 20a formed in the case 20 of the vent is fixed to the fixing groove 41 of the fixing cover 40 . is fastened to the</p>

<p>As described above, the retractable tuyere is configured to locally send cooling and heating to a desired part to obtain the effect of providing convenience to the occupants.</p>
