1 to 7, the headrest air conditioner according to the present invention includes a rear case 10, a duct 20, a mounting bracket 30, a blower 40, and a heater 50.

The rear case 10 is an injection-molded plastic product, and forms an empty space inside the headrest to provide a space in which the headrest air conditioner according to the present invention is installed.

A front case assembly 70 is coupled to the front of the rear case 10 to block the empty space from the outside. A cushion member is provided on the front of the front case assembly 70 so that the occupant can comfortably lean his head on it.

Two stay holes 11 through which the stays 60 pass are formed on the bottom surface of the rear case 10. A through area through which air can be smoothly sucked exists between the inner circumferential surface of the stay hole 11 and the outer circumferential surface of the stay 60, which is larger than the diameter of the stay 60. Therefore, the stay hole 11 serves as an inlet hole through which air is sucked into the headrest.

In addition, on the bottom surface of the rear case 10, a lower flow passage portion 12 coupled with the flow passage upper portion 22 (to be described later) of the duct 20 to form an air discharge passage is formed on the outer side of the stay hole 11. is formed in The lower passage 12 is formed in a downwardly inclined shape from the rear to the front of the bottom surface of the rear case 10, and a discharge hole 13 opening to the outside of the rear case 10 is formed at the front end thereof. .

The discharge hole 13 is formed in a slot shape that is substantially long in the left and right directions, and is not covered by the front case assembly 70 (see FIGS. 6 and 7 ).

In addition, the passages formed by the lower passage part 12 and the upper passage part 22 may be formed in a direction closer to each other from rear to front when viewed from a plan view. Accordingly, both discharge holes 13 are directed to the left and right sides of the rear surface of the neck, so that air can be blown over the entire rear surface of the neck.

In addition, on the inner surface of the rear case 10, a plurality of ribs 14 designed to secure necessary rigidity and reduce external transmission of vibration generated during operation of the blower 40 are combined with the front case assembly 70 Coupling parts 15 having hooks, locking grooves, etc. for the are formed.

The duct 20 is a plastic injection molding. The duct 20 serves to distribute the air discharged from the blower 40 in both directions and move it to the discharge holes 13 on both sides.

As shown in FIG. 2 , the duct 20 has a rectangular box-shaped center body 21 and a channel protruding in both directions from both sides of the center body 21 and then extending toward the front of the headrest while being curved in a soft curved shape. It includes the upper part (22). As described above, the passage upper part 22 is coupled with the passage lower part 12 of the rear case 10 to form an air discharge passage sealed against the outside.

A fixing piece 23 is formed protruding upward at the rear end of the beginning part (connecting part of the center body 21) of the upper side parts 22 of the both sides of the flow path, and is used to fix the duct 20 to the rear case 10. Corresponding to both fixing pieces 23, a pair of bosses 16 are protruded from the inner rear surface of the rear case 10, and screw holes are formed in the fixing pieces 23 and the boss 16, so that the screw 80 The duct 20 can be fixed to the rear case 10 by fixing the fixing piece 23 to the boss 16 by using (see Fig. 1).

The center body 21 has a bottom plate, a front wall, and a rear wall of the overall rectangular parallelepiped shape, and both side surfaces and top surfaces are formed in an open structure. That is, both side surfaces are in communication with the inside of the passage upper side portion 22, and the upper surface is open upward.

At the upper end of the center body 21, a seating end 21a into which the base plate 31 of the mounting bracket 30 is inserted and seated is formed on the inner side along the entire circumference. In addition, a guide seating end 21b into which the guide portion 31b formed on the base plate 31 is inserted is formed on the front wall of the center body 21 . The seating end 21a and the guide seating end 21b are formed with a step difference at a relatively low height with respect to the upper surface of the center body 21 and the upper surface of the front wall of the center body 21, respectively.

A heater 50 may be installed inside the center body 21 . The heater 50 is composed of a plurality of heater plates 51 . The heater plate 51 has planar heating elements 52 formed on one side or both sides of the substrate.

The planar heating element 52 is formed by applying a conductive paste containing CNT (Carbon Nano Tube), PCT (Poly-Cyclohexylene dimethylene terephthalate), and conductive metal powder to the surface of a substrate, and generates heat when power is supplied. Since the planar heating element 52 is formed on the entire side surface of the substrate, in the drawings (FIGS. 2 and 3), the heater plate 51 is simply shown without distinguishing the planar heating element 52 from the substrate on the side surface of the heater plate 51 The side of was marked with a planar heating element (52). In addition, wires connected to supply power to the planar heating element 52 are omitted.

The heater plates 51 are installed parallel to the air flow direction inside the center body 21 . That is, the heater plates 51 are disposed inside the center body 21 at regular intervals in the front-back direction, and the longitudinal direction of the heater plates 51 is the same as (parallel to) the left-right direction of the center body 21. installed

Both ends in the longitudinal direction of the heater plates 51 are fixed to the upper portions of both sides of the center body 21 (top of the inlet of the upper passage 22), or the lower surfaces of the heater plates 51 are the bottom surfaces of the center body 21. It can be installed in a fixed way. For example, by applying a structure in which a groove is formed at a corresponding portion of the center body 21 and the heater plates 51 are inserted and fixed into the groove, the heater plate 51 can be easily installed and removed.

As the heater plates 51 are installed in the above structure, the flow resistance by the heater plates 51 is minimized when the air discharged from the blower 40 passes through the center body 21 and moves to the upper side portions 22 on both sides of the passage. It can be. Also, in this state, heat is generated from the planar heating element 52 provided on one side or both sides of the heater plate 51, so that the air passing between the heater plates 51 is heated.

The mounting bracket 30 is a plastic injection molding. As shown in FIG. 3, the mounting bracket 30 includes a horizontal base plate 31, a back plate 32 vertically formed at the rear end of the base plate 31, and fixing parts 33 protruding from both ends of the back plate 32. ).

The base plate 31 is a plate material having the same rectangular shape as the upper opening of the center body 21 and is inserted into the seating end 21a of the center body 21 as described above. An inverted trapezoidal guide portion 31b protrudes downward from the center portion of the front end of the base plate 31, and the guide portion 31b has a guide seating end formed in the same shape on the front wall of the center body 21 ( 21b) is inserted and seated. When the base plate 31 is installed on the center body 21, the base plate 31 can be guided to the correct assembly position, and left and right movement is prevented after installation, helping to stably maintain the installed position.

As described above, when the base plate 31 is accurately installed on the center body 21, the fixing parts 33 on both sides are in close contact with the fixing pieces 23 on both sides of the duct 20, and the fixing part 33 and the fixed The screw holes formed in the pieces 23 coincide with each other. Therefore, the screw 80 can fix the fixing part 33 of the mounting bracket 30 and the fixing piece 23 of the duct 20 to the boss 16 of the rear case 10 together.

Since the base plate 31 and the seating end 21a of the center body 21 are fitted (press-fitted) with appropriate strength, the assembly state can be maintained without being separated from each other even before main assembly using the screw 80.

A rectangular coupling hole 31a is formed through the base plate 31 . The peripheral portion of the coupling hole 31a is also formed in a stepped structure like the seating end 21a so that the outlet 42 of the blower 40 can be inserted and seated in the coupling hole 31a. The outlet 42 of the blower 40 is press-fitted (press-fitted) into the coupling hole 31a of the base plate 31 and is not separated when the blower 40 operates. In addition, although not shown, by applying a widely used elastic hook & chin structure between the blower 40 and the mounting bracket 30 and coupling them to each other, it is of course possible to maintain the assembled state more firmly.

As shown in FIG. 4 , the heater 50 may further include a frame 53 . Since the heater plates 51 are installed inside the frame 53, the entire heater 50 may be configured as a single module.

That is, the heater plates 51 are not directly installed on the center body 21 of the duct 20, but are installed on the frame 53. The frame 53 is formed in a rectangular shape as a whole and can be fitted between the front and rear walls of the center body 21 . Alternatively, when the upper surface of the center body 21 is within a predetermined range and the heater installation hole 21c is formed on the upper surface, the frame 53 may be inserted into the heater installation hole 21c. Both side portions of the frame 53 are open to the side except for the upper portion to which the heater plate 51 is fixed, and thus have a sufficient passage area through which air can pass.

As described above, since the heater 50 is modularized, it is advantageous to attach and detach the heater 50 to the duct 20 more easily.

The blower 40 is equipped with a fan and a motor inside a substantially cylindrical case. The fan is rotated by the motor drive so that air can be sucked in and discharged. A suction hole 41 is formed on the side of the case and the outlet 42 is formed on the lower side. Therefore, when the fan rotates, air inside the headrest is sucked into the suction hole 41 and discharged through the outlet 42 .

As described above, the blower 40 may be fixed by press-fitting the outlet part 42 into the coupling hole 31a of the mounting bracket 30. Also, although not shown, the blower 40 may be fixed to the mounting bracket 30 via a separate fastening means. In addition, the blower 40 may be fixed to one side of the duct 20 as well as the mounting bracket 30 as needed.

However, the blower 40 is not fixed to the rear case 10. This is to prevent vibration generated during operation of the blower 40 from being directly transferred to the rear case 10 and transmitted to the head of the occupant through the front case assembly 70 coupled to the rear case 10 .

During actual assembly, first, the duct 20, the mounting bracket 30, and the blower 40 are assembled together, and the assembly is fixed to the inside of the rear case 10 by the screw 80. That state is shown in FIG. 5 .

Thereafter, the leg portions on both sides of the stay 60 assembled on the rear part of the front case assembly 70 are inserted into the stay holes 11 of the rear case 10, and the rear case 10 and the front case assembly 70 are When assembled, the assembly of the headrest is completed as shown in FIGS. 6 and 7 .

Now, the working effect of the headrest air conditioner according to the present invention will be described.

When the blower 40 is operated, the air inside the headrest is sucked into the suction hole 41 on the side of the blower 40, compressed by the fan, and discharged through the outlet 42. As much as the air inside the headrest is discharged to the outside through the blower 40, the air outside the headrest is supplemented into the inside of the headrest through the stay hole 11. That is, when looking at the entire headrest, the stay hole 11 serves as an inlet hole of the headrest air conditioner. In this way, the present invention is located on the bottom of the headrest, so the inlet hole of the headrest air conditioner is located. are located at a distance from the ears of the occupants, reducing air inflow noise felt by the occupants.

The air discharged from the blower 40 is introduced into the center body 21 of the duct 20 through the coupling hole 31a of the mounting bracket 30, and is distributed in both directions in the center body 21 to both flow passages ( It moves through the passage formed by the upper passage part 22 and the lower passage part 12) and is discharged into the discharge hole 13.

At this time, since the upper part 22 of the passage 22 is gently curved toward the front of the headrest from the center body 21, when the air passes through the inside of the passage and changes direction, flow noise generated by collision with the inner wall is reduced. .

Meanwhile, the passage formed by the upper passage 22 of the duct 20 and the lower passage 12 of the rear case 10 is formed in a downwardly inclined state from the rear to the front of the headrest. Therefore, as shown in FIG. 8, the air discharged from the discharge hole 13 has a downward inclination angle θ with respect to the horizontal line (line B-B) as shown by arrow A. That is, the air discharged from the discharge hole 13 of the headrest may be inclined downward and supplied toward the occupant's neck (N) and shoulder (S). The air supplied to the shoulder (S) moves to the front (chest side) of the shoulder along the curved surface of the shoulder, so that air can be blown to the front of the upper body as well. In addition, it goes without saying that air can also move toward the rear (dorsal) side of the shoulder along the curved surface of the shoulder. As the air discharged from the discharge hole 13 is blown downward toward the shoulder as described above, an air curtain covering the front and rear surfaces of the shoulder can be formed by the Coanda effect caused by the upper curved surface of the shoulder.

At this time, the discharge hole 13 is formed on the bottom surface of the headrest far from the occupant's ears, and the air discharge direction is also inclined downward, so that the air gradually moves away from the occupant's ears. There is an effect of reducing air discharge noise.

In addition, since the passages formed by the upper passage part 22 and the lower passage part 12 are located on both left and right sides of the headrest, and the passages are formed in a direction from the rear to the front of the headrest, they are closer to each other. Air is discharged from the discharge hole 13 toward the left and right rear surfaces of the neck N, respectively.

Therefore, as shown in FIG. 9 , air discharged from both discharge holes 13 can be blown to the entire rear surface of the neck N (quadrant 1 and quadrant 2 in the plan view of the neck). In addition, part of the air discharged from the discharge holes 13 on both sides follows the shape of the surface of the curved surface of the neck N by the Coanda effect (a phenomenon in which the flow flows along the surface of the contact curved surface due to viscosity). ), it is possible to blow air to the front of the neck (N) (third and fourth quadrants in the neck plan view). In this way, an air curtain covering the entire circumference of the occupant's neck N may be formed by the air discharged from the discharge hole 13 .

On the other hand, as shown in FIG. 9, the rear end of the passage including the discharge hole 13 may be formed as a separate passage member 25, and the passage member 25 is centered around the rotation center point C at the rear end. The front end, that is, the discharge hole 13 side portion may be installed so that it can be rotated in the left and right directions. In this way, by adjusting the discharge direction of the discharge hole 13, the air blown to the neck N is concentrated toward the center of the back of the neck N or the amount of air moving to the front of the neck N is increased. Depending on the convenience of the occupant, the ventilation condition can be changed.

As described above, according to the present invention, before the indoor temperature is changed to the desired set temperature by the main air conditioner of the vehicle, the headrest air conditioner is operated to operate (very quickly) the entire circumference of the neck and the front of the shoulder By forming an air curtain surrounding the rear surface and the rear surface, the occupant can more quickly feel thermal comfort by cool or warm air.

Meanwhile, the heater 50 includes a plurality of heater plates 51, and a planar heating element 52 is formed on one side or both sides of the heater plate 51. Therefore, unlike heaters using hot wires used in conventional headrest air conditioners, the heat exchange area is wide and more efficient air heating is possible. Therefore, since there is no need to generate excessively high heat in the heater plate 51, air can be sufficiently heated even in a relatively low-temperature heating state. Accordingly, there is an effect of reducing power consumption used by the heater 50 .

In addition, since the heater plates 51 are installed parallel to the air movement direction, the flow resistance generated by the heater 50 is small, and accordingly, in order to secure sufficient blowing pressure against the flow resistance, the blower 40 ), there is no need to increase the rotational speed. Therefore, it is possible to operate by reducing the rotational speed of the blower 40 or to apply a blower with a small capacity. Therefore, noise and vibration of the blower 40 are reduced, and power consumption is reduced.

As described above, according to the present invention, the air intake and discharge noise felt by the occupant is reduced when the headrest air conditioner is operated, and the air conditioning wind is supplied to the entire circumference of the occupant's neck and the front and rear surfaces of the shoulder of the occupant. device is provided.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is only exemplary, and various modifications and equivalent other embodiments are possible based on common knowledge in the field to which the technology belongs. should understand Therefore, the true technical protection scope of the present invention is based on the claims to be described below, and should be determined based on the specific contents of the above-described invention.
