Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide door device provided in an air conditioning unit for a vehicle.

[0002]

2. Description of the Related Art Conventionally, as an air conditioning unit for a vehicle having a sliding door device (mechanism), as shown in FIG.
A unit case 1 includes a blower (blower) 2, a cooling heat exchanger (evaporator) 3, a heating heat exchanger (heater core) 4, and the like. A sliding door device 5 is provided downstream of the cooling heat exchanger 3 to control the distribution of air to the downstream of the cooling heat exchanger 3.

As shown in FIG. 1, the air conditioning unit for a vehicle uses the air blown from the blower 2 to the air passing only through the cooling heat exchanger 3 and the heating heat from the cooling heat exchanger 3. The air that has passed through the exchanger 4 is mixed again so that the air can be mixed and adjusted to a predetermined blowing temperature. The conditioned air rises along the unit case inner wall surface 1A located on the vehicle interior side, and is then blown out from the indoor air outlet 6 into the vehicle interior. The sliding door device 5 controls the opening area of the opening frame 7 by sliding an air mixing door (sliding plate) 8 so that the air passing through the cooling heat exchanger 3 is connected to the indoor air outlet 6 and the heating air outlet 6. Arbitrary air distribution is performed to the heat exchanger 4 side.

[0004]

Considering the case where cold air and hot air are mixed one-to-one in the air conditioning unit for a vehicle shown in FIG. 8, the air passing through the heat exchanger 3 for cooling is slid on the sliding door. The temperature is controlled by controlling the opening degree of the air mix door 8 in the device 5 to be １ ／, that is, the opening areas of the cold air passage and the warm air passage are substantially equal. Here, so that the opening degree of the air mix door 8 becomes 100% of the cool air,
When the cooling air is controlled not to be sent to the heating heat exchanger 4 (at the time of full cooling),
When the ventilation resistance is compared with the case where air is distributed only to the heating heat exchanger 4 side (at the time of full hot) so that the opening degree of the hot air is 100%, the vehicle air as shown in FIG. Due to the structure of the harmony unit, the ventilation resistance in the case of full cooling is lower than the ventilation resistance in the case of full hot. this is,
The air coming out of the sliding door device 5 is directly transmitted to the indoor outlet 6.
Unit case 1 because the air flowing to the side has a short passage distance
In contrast, the air coming out of the sliding door device 5 passes through the heating heat exchanger 4 and the case inner wall surface 1A on the rear side of the vehicle in the unit case 1 although the contact with the inner wall and the change in the blowing direction are small. It is thought that this is caused by a large change in the blowing direction when the passing distance becomes long because the airflow rises along the path.

[0005] As a result, when it is desired to mix the cold wind and the warm wind in a one-to-one manner, of the wind passing through the sliding door device 5, the amount of the wind or the force of the wind heading toward the indoor outlet 6 becomes the warm wind. There has been a problem that the air flow becomes larger than the wind volume or the wind force, so that the cold wind and the warm wind are hardly mixed, and that the temperature difference between the upper and lower winds tends to occur.

Therefore, the present invention has been made in view of such problems, and contributes to downsizing of an air conditioning unit for a vehicle and improves the mixing performance of cold air and hot air. An object is to provide a sliding door device.

The sliding door device that variably performs the above, the slide plate is movably provided on a frame having an air blowing opening, and the opening area of the air blowing opening on the side that directly blows air to the plurality of air blowing passages. Is set smaller than the opening area of the blower opening for blowing air to the heating heat exchanger.

[0008] According to the first aspect of the present invention, the cool air flowing from the cooling heat exchanger to the air blowing passage is provided.
In consideration of the ventilation resistance with the warm air that goes round to the air blowing passage through the heating heat exchanger, by setting the area of the ventilation opening of the slide door device as described above, the ventilation resistance is received. Ensuring the volume of warm air that tends to be low,
The mixing efficiency of the cold air and the hot air is improved.

According to a second aspect of the present invention, there is provided the slide door device according to the first aspect, wherein an opening area of the air blowing opening on a side for directly blowing air to the plurality of air blowing passages, An opening area of the blow opening for blowing air to the heating heat exchanger is defined by a rib provided on the frame.

Therefore, according to the second aspect of the present invention, by appropriately setting the width and the like of the rib provided on the frame of the sliding door device, the air volume on the warm air side can be secured.

Air distribution can be performed according to In addition, since the partitioning plate for dispersing and mixing the cool air and the warm air is provided on the upstream side of the frame, the warm air and the cool air can be efficiently harmonized without increasing the space.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of a sliding door mechanism according to the present invention will be described below using embodiments shown in the drawings.

(Embodiment 1) FIG. 1 is a perspective view showing a sliding door device according to Embodiment 1 of the present invention, and FIG.
It is -A sectional drawing. The slide door device 9 includes a substantially rectangular frame 11, a slide plate 12 slidable on the frame 11, a drive shaft 13 rotatably supported in the width direction of the frame 11, and a drive shaft 13. A drive gear 14 supported by the shaft 13 and meshing with a rack tooth 12A engraved on the slide plate 12 and a drive force transmission gear 15 to which rotational driving force is transmitted from a rotational driving means (not shown) for rotationally driving. Prepare.

As shown in FIG. 1, the frame 11 has a pair of frame side plates 16, 16 formed by an arc and a chord in which a circle is cut by a chord. 16 are arranged on both sides in the width direction w to face each other. In the center of each frame side plate portion 16, a bearing opening (not shown) is opened. On the surfaces of the frame side plates 23 facing each other, slide guide grooves 17 each having a substantially arc shape are formed along arc edges.

The distance between the frame side plates 16, 16 is set substantially equal to the width of the air passage area of the cooling heat exchanger described later. These frame side plates 1
Opposite ends of 6 and 16 are connected by frame horizontal frame portions 18 and 19, respectively. Further, along the arc-shaped edges of the frame side plate portions 16, 16, the guide plate portion 20 having a shorter width dimension from the lower half of the edge portion toward the inside facing the opposite side,
20, and guide plate portions 21 and 21 having a long width dimension are formed from the upper half of the edge portion toward the inside in the opposite direction. The guide plates 20, 21 are set to the same length.

The center portions of the horizontal frame portions 18 and 19 in the width direction w are connected to each other by a central guide plate portion 22 that is curved similarly to the guide plate portions 20 and 21. Further, the boundary between the guide plates 20 and 21 and the center of the central guide plate 22 in the vertical direction h (indicated by an arrow in FIG. 1) are connected by a reinforcing horizontal plate 23. As a result, the curved opening surface formed by the frame horizontal frame portions 18 and 19 and the guide plate portions 20 and 21 is divided into a cross shape by the central guide plate portion and the reinforcing horizontal plate portion 23. Then, two upper openings 24A, 24A located on the upper side of the frame 11 and two lower openings 24B, 24B located on the lower side of the frame 11
Are formed. In addition, as shown in FIG. 1, the frame horizontal frame part 18 is formed wide, and the frame horizontal frame part 19 is formed narrow. As a result, the upper opening 24A,
24A is set narrower than the lower openings 24B, 24B.

The slide plate 12 is connected to the frame 11 described above.
It is a rectangular plate curved in the same manner as the degree of curvature of the curved opening surface, and is arranged inside the curved opening surface of the frame 12. Slide pins (not shown) which project outward in the width direction w and are slidably housed in the slide guide grooves 17 are integrally formed at upper and lower ends of both side edges in the width direction w of the slide plate 12. Has been established. The rack teeth 12A described above are engraved on the curved inner surfaces of both side edges in the width direction w of the slide plate 12 along the side edges. The dimension of the slide plate 12 in the width direction w is set slightly shorter than the distance between the pair of frame side plates 16 of the frame 11. The dimension of the slide plate 12 in the up-down direction h is set slightly longer than the length of the guide plate portion 20 (21) of the frame 11, and when the slide plate 12 is mounted on the frame 11, a pair of upper Opening 24
A, 24A and one of the pair of lower openings 24B, 24B are set so that they can be completely closed or opened.

The sliding door device 10 having such a configuration is described.
Is incorporated in the vehicle air conditioning unit 30 as shown in FIG. The vehicle air conditioning unit 30 is shown in FIG.
As shown in (1), a blower (blower) 32, a heat exchanger for cooling (evaporator) 33, a heat exchanger for heating (heater core) 34, and the like are arranged in a unit case 31. The sliding door device 10 is disposed downstream of the cooling heat exchanger 33,
To control the air flow to the downstream side.

As shown in FIG. 2, the vehicle air conditioner unit 30 converts the air blown from the blower 32 into the air passing only through the cooling heat exchanger 33 and from the cooling heat exchanger 33 into the heating air. The air that has passed through the heat exchanger 34 is mixed again so that the air can be mixed and adjusted to a predetermined blowing temperature. That is, the heating heat exchanger 33
Is passed through the unit case wall 3
After ascending along 1A, the air is mixed with the cool air in the air mix chamber 35 and blown out from the various indoor-side outlets 36, 37, 38 toward the passenger compartment. The sliding door device 10 controls the opening area of the opening frame 11 by sliding the sliding plate 12 so that the air passing through the cooling heat exchanger 33 is supplied to the air mixing chamber 35 and the heating heat exchanger 4 side. And any air distribution is done.

Normally, in such an air conditioning unit 30 for a vehicle, the air flowing out of the cooling heat exchanger 33 directly travels toward the indoor side outlets 36, 37 and 38, and has a short passage distance. Therefore, the contact with the inner wall of the unit case 31 and the change in the blowing direction are small, but the air that has exited from the slide door device 10 passes through the heating heat exchanger 34 and is located on the rear side of the vehicle in the unit case 31. It rises along the case inner wall surface 31A. For this reason, the passage distance becomes longer, and the blowing direction changes greatly, so that the passage resistance increases. As a result, of the winds that have passed through the sliding door device 10, the amount of wind toward the indoor outlet 6 is larger than the amount of warm air, and it is difficult for the cool air and the warm air to be mixed well. The difference in temperature easily occurs.

However, in the first embodiment, as shown in FIG. 1, for example, when the slide plate 12 is located at the center of the frame 11, the sum of the opening areas of the upper openings 24A, 24A is equal to the lower opening. It becomes smaller than the sum of the opening areas of 24B and 24B. Therefore, due to the dispersing action of the sliding door device 10, the lower opening 24B,
The amount of air flowing to the heating heat exchanger 34 after passing through 24B is:
Larger than the air volume passing through the upper openings 24A, 24A,
Wind volume and wind force (wind pressure) on the warm wind side that is easily affected by passage resistance
Can be secured. As a result, the winds of the cold wind and the warm wind can be made equal to each other and mixed well in the air mix chamber 35, and a difference in temperature is generated in the wind blown to each of the indoor side outlets, causing discomfort to the occupants. Feeding can be prevented.

In the first embodiment, the widths of the frame portions 18 and 19 of the frame 11 of the sliding door device 10 are made different, and the widths of the guide plates 20 and 21 are made different. , Upper opening 24A, 24A
Is set to be smaller than the sum of the opening areas of the lower openings 24B, 24B, but any configuration can be used as long as the air volume on the heating heat exchanger 34 side can be substantially secured. For example,
In the sliding door device 10, the frame horizontal frame portion 18,
19 and the width dimensions of the guide plate portions 20 and 21 were appropriately set.
The frame may be appropriately provided with ribs.

With the slide door device 10 mounted in the unit case 31 as described above, the driving force transmitting gear 15 mounted on the end of the drive shaft 13 is provided with a rotating mechanism (not shown) on the rotation driving means side. The transmission connection portion is connected, and by controlling the rotation driving means, the driving force transmission gear 15 rotates to move the slide plate 12 to an appropriate position to control the opening area.

(Embodiment 2) FIG. 4 is an exploded perspective view showing a slide door device according to Embodiment 2 of the present invention, FIG. 5 is a longitudinal sectional view, and FIG. 3 is an explanatory sectional view of an air conditioning unit for a vehicle. . The second embodiment is an example in which the present invention is applied to a thin second slide door device 40 arranged on the outlet side of an air conditioning unit for a vehicle described later.

The second sliding door device 40 includes a frame 41 and a pair of sliding plates 42, 42 arranged inside the frame 41 and performing sliding operations. The frame 41 opposes a pair of frame side plates 43, 43 having arc-shaped edges, separated by a predetermined distance,
Four frames 44, 45, 4 connecting the edges
The openings 6 and 47 are formed so as to divide the area of the opening into three equal parts. The openings serving as air passages are three openings: an opening 48 corresponding to a ventilator duct (not shown), an opening 49 corresponding to a defroster opening, and an opening 50 corresponding to a foot opening. As shown in FIG. 4, the lower half of the upstream surface of the frame 41 includes frame side plate portions 43, 43.
The partition plate 51 is formed over the range. The lower edge of the partition plate 51 is formed integrally with the frame horizontal frame portion 47. Also, as shown in FIG.
Is set so as to form a predetermined angle with respect to the opening surface of the opening 50 between the frame horizontal frame portions 46 and 47.

The slide plates 42, 42 are set to have such a width as to completely close one opening 48 (49, 50). In addition, these slide plates 42, 42
It is a rectangular plate curved in the same manner as the degree of curvature of the curved opening surface of the frame 41 described above, and is disposed inside the curved opening surface of the frame 41. Also, the slide plate 42
The upper and lower ends of both side edges in the width direction w are slidably accommodated in slide guide grooves 52, 52 protruding outward in the width direction and formed along the arc on the inner side surface of the frame side plate portion 43. Slide pins 42A, 42A are integrally protruded. Further, the rack teeth 42B, 42B described above are engraved on the curved inner surfaces of both side edges in the width direction of the slide plates 42, 42 along the side edges. This slide plate 42
Is set to be slightly shorter than the distance between the pair of frame side plates 43, 43.

The slide plates 42, 42 are moved by a drive gear provided on a drive shaft (not shown) rotatably mounted between the frame side plates 43, 43. Reference numeral 53 in FIG. 4 denotes a driving force transmission gear provided at an end of the driving shaft protruding outside the frame 41, and meshes with a gear (not shown) on the driving force generating means side.

The second sliding door device 4 having such a configuration
0 is incorporated in the vehicle air conditioning unit 50 as shown in FIG. As shown in FIG. 5, the air conditioning unit 50 for a vehicle is provided with a blower (blower) 32 above a unit case 51. In addition, a cooling heat exchanger (evaporator) 5 is provided below the unit case 51.
3. A first sliding door device 54, a heat exchanger for heat (heater core) 55, and the like are arranged.

Then, the above-mentioned second sliding door device 4
Numeral 0 is disposed on the upper side of the mix chamber 56 of the unit case 51 on the indoor outlet side. Further, the first sliding door device 54 is disposed downstream of the cooling heat exchanger 53, and controls air blowing to the downstream of the cooling heat exchanger 53. Note that the first sliding door device 54 has a structure having one slide plate 56 as in the conventional sliding door device. That is, the first slide door device 54 includes a frame 57, a slide plate 56 slidable on the frame 57, a drive shaft 58, and the drive shaft 5.
And a rotation driving unit (not shown) for transmitting a rotation driving force to the driving force transmission gear 59 provided in the drive unit 8.

The air conditioning unit 50 for a vehicle is shown in FIG.
As shown in (2), the air blown out from the blower 52 is sent to the cooling heat exchanger 53 along the inner wall surface 51A on the vehicle front side of the unit case 51. At this time, the first sliding door device 54 sends the wind from the blower 52 to the heat exchanger 53 for cooling.
Side and the heating heat exchanger 55 side. Then, the air passing only through the cooling heat exchanger 53 and the air passing from the cooling heat exchanger 53 through the heating heat exchanger 55 are
By mixing again in the air mix chamber 56, mixing and harmony can be achieved at a predetermined blowing temperature. That is, the air that has passed through the heating heat exchanger 55 rises along the unit case wall surface 51B on the vehicle compartment side, is mixed with the cool air in the air mix chamber 56, and passes through the second slide door device 50. , Ventilator duct, defroster port, foot port, etc., are blown out to the passenger compartment side from various indoor side outlets.

In the vehicle air conditioner 50 provided with such a second slide door device 40, a partition plate 51 of the second slide door device 40 is disposed upstream of a foot port and a defroster port (not shown). Therefore, when the temperature is adjusted according to the air outlet of each mode by the wind dispersion action of the partition plate 51, the hot and cold air is sufficiently mixed in the same space as in the related art, so that a good air mixing effect can be obtained.

Further, in the combined mode, for example, when air is blown into the vehicle interior from the ventilator duct and the foot opening, since the hot and cold air is sufficiently mixed, the vertical temperature difference of the blown air becomes small, and the target temperature is reduced. There is an advantage that adjustment becomes easy.

Further, in the second slide door device 40, the combination of the positions of the two slide plates 42 makes it possible to easily control the temperature of the outlet and to easily select and select adjacent outlets. Become.

In the second embodiment, the openings 48, 49, and 50 of the second sliding door device 40 are sequentially opened.
Although positioned so as to correspond to the ventilator duct, defroster port, and foot port, the foot port may correspond to the opening 49. By arranging the foot opening in the center in this way, it is possible to sufficiently mix hot and cold air in the same space as in the related art when adjusting the outlet temperature according to the mode outlet. Further, in this case, the upper and lower differential temperature in the combined mode has an advantage that the partition plate 51 facilitates the temperature adjustment of the upper and lower differential temperature according to the target value (to make the temperature difference from the isothermal one). Further, by arranging the foot opening at the center, the outlet temperature controllability can be improved. Furthermore, in the second sliding door device 50, by arranging the foot opening at the center, the two sliding plates 42, 42 can be in the same sliding groove when changing from the VENT mode to the DEF mode and from the DEF mode to the VENT mode. Since it is only necessary to move along the line 52, the drive system design can be simplified.

Although the first and second embodiments have been described above, the present invention allows various design changes accompanying the gist of the configuration. For example, in Embodiment 1 described above,
Although the frame 1 and the slide plate 12 constituting the slide door device 10 are curved so as to swell to the downstream side, it is of course possible to use a flat frame or slide plate. In the slide door device 10 according to the first embodiment, the area of the opening closer to the outlet is
Although the widths of the guide plates 21, 21 and the frame horizontal frame 18 are set to be large and small, it is needless to say that ribs may be appropriately arranged so as to straddle the opening.

In the second embodiment, as shown in FIG. 5, the lower edge of the partition plate 51 is
However, it may be formed so that a slit is provided in the horizontal direction between the lower edge of the partition plate 51 and the frame horizontal frame portion 47.
