Description of embodiments

The inventor carried out a study on a configuration as described in US Pat 35 . 36 and 37 is shown, in which a guide section J2 on a rotating mode door in a vehicle air conditioner J1 configured to have a mode flap area and an air mix area combined into an area inside an air conditioning case. Hereinafter, the configuration will be referred to as the case under investigation (the comparative example). The inventor found that a phenomenon occurs in the case of investigation which will be described below.

In the vehicle air conditioning J1 are a defroster opening section 11 , a front opening section 12 as well as a foot opening section 13 sequentially in a stream of air downstream (upper Page in the drawings) of a mode flap 50 arranged, and a passage 14 for cold air is on one side of the defroster opening section 11 arranged, and a passage 15 for warm air is on one side of the foot opening section 13 arranged, both upstream in the airflow (lower side in the drawings) of the mode flap 50 , As the mode flap 50 and an air mix door 40 In each case a rotary valve is used. The mode flap 50 and the air mix door 40 are arranged coaxially. As a result, the cold air and the warm air, before mixing, flow directly into the mode door 50 into it, and the cold air and warm air inside the mode flap 50 ,

The mode flap 50 has a first flap opening section 55 and a second flap opening section 56 on, which is on an opposite side. The guide section J2 extends from the first flap opening section 55 the mode flap 50 towards a central position of the mode flap 50 , An end J21 of the guide section J2 is located at a position where the one end J21 the first flap opening section 55 divided into two opening sections. The guide section J2 extends in a direction perpendicular to the leaf surfaces of the 35 . 36 and 37 that is, in an axial direction of a rotary shaft of the mode door 50 , and it points in the axial direction of the mode flap 50 a uniform shape.

As in 35 is shown, is the guide section J2 positioned in a bi-level mode so that he gets cold air C and warm air H that directly into the mode flap 50 into the interior of the mode flap 50 separates and the cold air C to the front opening section 12 and the warm air H to the foot opening section 13 leads. As a result, a temperature difference between air coming from a front outlet through the front opening section 12 is blown into a vehicle interior and air discharged from a foot outlet through the foot opening section 13 is blown through into the vehicle interior, that is, a temperature difference between an upper portion and a lower portion may exceed a target value.

As each in the 36 and 37 is shown, is the guide section J2 in a foot mode and a foot defroster mode positioned so that a clash of warm air H and the cold air C is forced by a stream of warm air H is diverted. After a clash of cold air C and the warm air H and mixing them accordingly reaches a mixed air M the defroster opening section 11 and the foot opening section 13 ,

However, even in such a case, since the mixing of the cold air flows C and the warm air H is not enough, the cold air C from the passage 14 for cold air near the defroster opening section 11 into the defroster opening section 11 into it, while the warm air H from the passage 15 for warm air near the foot opening section 13 in the foot opening section 13 flows into it. As a result, there is a proportion of cold air in the mixed air M high, the defroster opening section 11 achieved while a share of warm air in the mixed air M is high, the foot opening section 13 reached. Because only a little warm air the defroster opening section 11 Achieved, a temperature difference between the air coming from the defroster outlet through the defroster opening section 11 is blown through into the vehicle interior and the air flowing from the foot outlet through the foot opening section 13 is blown into the vehicle interior, that is, a temperature difference between an upper portion and a lower portion, possibly exceed the target value.

By the guide section J2 is extended, as in 37 shown by a dashed line to the other end J22 of the guide section J2 near the passage 14 For cold air, the cold air and the tub air come closer together and mix sufficiently. In such a case, however, the guide portion decreases J2 which is in the axial direction of the mode flap 50 has a uniform shape, the cut surfaces of the passages for the cold air and the warm air. As a result, since a pressure loss is increased, the configuration as above can not be used.

Except for a case where a rotary door is used as the air mix door, the phenomenon described above also occurs in a case where other types of doors, such as a sliding door, are used as the air mix door in the configuration in which the Mode Flap Area and the Air Blend area are combined into one area.

In the following, several embodiments for realizing the present invention will be described with reference to the drawings. In the respective embodiments, a portion corresponding to an article described in a preceding embodiment may be assigned the same reference numeral, and a redundant explanation for the portion may be omitted. If in one embodiment only a portion of a Configuration is described, another previous embodiment can be applied to the other parts of the configuration. The cuts can be combined, although it is not explicitly described that the cuts can be combined. The embodiments may be partially combined, although it is not explicitly described that the embodiments may be combined provided there is no damage to the combination.

More precisely, the baffle section is located 71 at a position between the axial position 54a the rotary shaft 54 and the air mix door 40 , As indicated by arrows in the drawing, meet accordingly cold air C1 and warm air H1 on each other and mix, and a resulting mixed air M1 flows towards the front opening section 12 and the foot opening section 13 ,

As in 7B is shown, is the first guide section 81 in the second room section 62 on the other hand positioned so that a clash of warm air H2 from the passage 15 for warm air and cold air is forced by the warm air H2 towards a middle of the mode flap 50 is diverted. The second guide section 82 is along a cold air C2 arranged by the passage 14 for cold air on the front opening section 12 and the foot opening section 13 heading. As indicated by arrows in the drawing, meet the cold air C2 and the warm air H2 corresponding to each other and mix, and a resulting mixed air M2 flows towards the front opening section 12 and the foot opening section 13 ,

As a result, the mixed air M1 and the mixed air M2 from cold air and warm air through the front opening section 12 or the foot opening section 13 blown out through the front outlet and the foot outlet.

In a foot mode, in the 8A and 8B is shown, is the mode flap 50 at a position where the outer peripheral wall 51 the defroster opening section 11 almost closes and the front-opening section 12 closes while the first flap opening section 55 with the foot opening section 13 communicates with it and the second flap opening section 56 is possible with the passage 14 for cold air and the passage 15 to communicate for warm air. The air mix door 40 is located at a position where the air mix door 40 a passage sectional area of the passage 14 for cold air downsized and a passage cut surface of the passage 15 enlarged for warm air.

As in 8A is shown, the baffle section 71 herein in the first space section 61 positioned so that a stream of cold air C1 in the first room section 61 is confined in while the warm air H1 to the defroster opening section 11 is guided by the warm air H1 is possible in the first room section 61 to pour into it. More precisely, the baffle section 71 arranged so that it moves from a position closer to the end 141 of the passage 14 for cold air on the side of the defroster opening section is at the end 142 of the passage 14 for cold air on the side of the warm air passage, towards the passage 15 for warm air. As a result, the baffle section closes 71 the first room section 61 on the side of the passage 14 for cold air. As indicated by arrows in the drawing, accordingly, a flow of cold air C1 in the first room section 61 limited in, and therefore flows the cold air C1 in the adjacent second space section 62 into it. The warm air H1 meanwhile flows into the first room section 61 and flows toward the defroster opening section 11 and the foot opening section 13 ,

As in 8B is shown are the first guide portion 81 and the second guide section 82 in the second room section 62 on the other hand positioned so that a meeting of the warm air coming from the passage 15 for warm air has flowed into the interior, and the cold air coming from the passage 14 For cold air has flowed into the interior, forced by both the cold air and the warm air to be redirected. The first guide section 81 is positioned so that the warm air H2 towards the axial position 54a is diverted. The second guide section 82 is positioned so that the cold air C2 towards the axial position 54a is diverted. As indicated by arrows in the drawing, the cold air mix C2 and the warm air H2 accordingly, and a mixed air M21 and a mixed air M22 that result, flow in the direction to the defroster opening section 11 or the foot opening section 13 ,

As a result, the warm air is flowing H1 from the first room section 61 and the mixed air M21 from the second space section 62 through the defroster opening section 11 through, while the warm air H1 from the first room section 61 and the mixed air M22 from the second space section 62 through the foot opening section 13 flow through it.

In a foot-defroster mode, in the 9A and 9B is shown, is the mode flap 50 at a position where the outer peripheral wall 51 the front opening section 12 closes while the first flap opening section 55 with the foot opening section 13 communicates with it and the second flap opening section 56 is possible with the passage 14 for cold air and the passage 15 for warm air, and he with the defroster opening section 11 communicates. The air mix door 40 is located at a position where the air mix door 40 a passage sectional area of the passage 14 for cold air downsized and a passage cut surface of the passage 15 enlarged for warm air.

As in 9A is shown, there is the baffle section 71 herein in the first space section 61 at a position substantially the same as the position in the foot mode. As indicated by arrows in the drawing, accordingly, a flow of cold air C1 in the first room section 61 limited in, and therefore flows the cold air C1 in the adjacent second space section 62 into it. The warm air H1 meanwhile flows into the first room section 61 and flows toward the defroster opening section 11 and the foot opening section 13 ,

As in 9B is shown, are the first guide section 81 and the second guide section 82 in the second room section 62 on the other hand, at positions substantially the same as the positions in the foot mode. As indicated by arrows in the drawing, the cold air mix C2 and the warm air H2 accordingly, and the mixed air M21 and the mixed air M22 that result, flow toward the defroster opening section 11 or the foot opening section 13 ,

As a result, the warm air is flowing H1 from the first room section 61 and the mixed air M21 from the second space section 62 through the defroster opening section 11 through, while the warm air H1 from the first room section 61 and the mixed air M22 from the second space section 62 through the foot opening section 13 flow through it.

In a defroster mode, in the 10A and 10B is shown, is the mode flap 50 at a position where the outer peripheral wall 51 the front opening section 12 and the foot opening section 13 closes while allowing the second flap opening section 56 with the passage 14 for cold air and the passage 15 for warm air, and he with the defroster opening section 11 communicates. In the 10A and 10B is the air mix door 40 at a position for maximum heating, where the air mix door 40 the passage 14 for cold air closes and a passage-sectional area of the passage 15 increased to a maximum for warm air. As a result, the second flap opening section stands 56 in a state that is in the 10A and 10B is shown with the passage 15 for warm air.

As in 10A is shown, the baffle section 71 in the first room section 61 in the defroster mode, positioned so that a stream of warm air H1 not blocked by the passage 15 for warm air on the defroster opening section 11 heading. More precisely, the baffle section 71 arranged so that it is from one end 111 the defroster opening section 11 on the side of the cold air passage towards the passage 15 for warm air. As indicated by an arrow in the drawing, the warm air becomes H1 accordingly through the defroster opening section 11 blown out of the defroster outlet.

As in 10B is shown are the first guide portion 81 and the second guide section 82 in the second room section 62 on the other hand positioned so that a stream of warm air H2 not blocked by the passage 15 for warm air on the defroster opening section 11 heading.

As a result, the warm air H1 and the warm air H2 from the passage 15 for warm air through the defroster opening section 11 blown out through the front outlet.

In the case of investigation, the leading section J2 used as it is in 35 is shown, the guide section separates J2 the cold air C and the warm air H, which in the bi-level mode directly into the mode flap 50 have poured into it. As a result, a temperature difference between blowing air from the front outlet and Blowing air from the foot outlet, that is, a temperature difference between an upper section and a lower section, may exceed a set point.

In contrast, the first guide section act 81 and the second guide section 82 in the second room section 62 in the present embodiment, in the bi-level mode, a cold air collision C2 and the warm air H2 to force and to mix these. Furthermore, the baffle section 71 in the first room section 61 positioned so that mixing the cold air C1 and the warm air H1 which is possible in the mode flap 50 have poured into it. As a result, the baffle section separates 71 the cold air C1 and the warm air H1 Not. Even if the baffle section 71 in the first room section 61 is provided, mix the cold air C1 and the warm air H1 accordingly and reach the front opening section 12 and the foot opening section 13 , As a result, a temperature difference between an upper portion and a lower portion according to the present embodiment can be reduced, and as a result, a temperature difference between an upper portion and a lower portion can be approximated to the target value as compared with the examination case discussed above.

As each in the 36 and 37 is shown, the guide portion acts J2 in the foot mode and the foot defroster mode in the case of the investigation, a clash of the warm air H and the cold air C to force it, adding a stream of warm air H is diverted. Because the cold air C and the warm air H however, in such a case, only a small amount of warm air reaches the defroster opening section 11 , and a temperature difference between the blown air from the defroster outlet and the blown air from the foot outlet, that is, a temperature difference between an upper portion and a lower portion may possibly exceed the target value.

In contrast, the first guide section act 81 and the second guide section 82 in the second room section 62 in the foot mode and the foot defroster mode in the present embodiment, respectively, collision and mixing of cold air C2 and the warm air H2 to effect. Furthermore, the baffle section is limited 71 in the first room section 61 a stream of cold air C1 in the first room section 61 into it, while the warm air H1 to the defroster opening section 11 is guided by allowing the warm air H1 in the first room section 61 flows into it. Accordingly, the warm air H1 from the passage 15 for warm air to the defroster opening section 11 in the first room section 61 be guided without the cold air C1 to be overlaid. Because it allows more bucket air to enter the defroster opening section 11 Accordingly, a temperature difference between an upper portion and a lower portion according to the present embodiment can be approximated to the target value as compared with the case under investigation.

Second embodiment

As in 11 to 15 is shown, the present embodiment includes a guide portion 72 in addition to the configuration of the above first embodiment. Except the difference as above, the present embodiment has the same configuration as the above first embodiment. The guide section 72 is in a first room section 61 provided and sits down to partitions 57 away. The guide section 72 is arranged so that it is from one end 551 a first flap opening section 55 in a circumferential direction toward an axial position 54a a rotary shaft 54 extends. At the end 551 of the first flap opening section 55 in the circumferential direction is an end closer to a second flap opening section 56 lies.

The guide section 72 is arranged to function in predetermined modes in respective outlet modes. In a front mode, in 11 is shown, is the guide section 72 positioned so that it has a stream of cold air C1 not blocked by a passage 14 for cold air on a front opening section 12 heading. In a defroster mode, the in 12 is shown, is the guide section 72 positioned so that a stream of warm air H11 and a stream of warm air H12 Do not be blocked by a passage 15 for warm air on a defroster opening section 11 heading.

In a bi-level mode, in 13 is shown, is the guide section 72 positioned so that a clash of troughs air H1 from the passage 15 for warm air and cold air C1 is enforced by the warm air H1 towards the passage 14 is deflected for cold air. Accordingly, in comparison with the above first embodiment, in which the guide portion 72 is absent, a mixing of the cold air and the warm air are promoted, and as a result, a temperature difference between an upper portion and a lower portion can be reduced. As a result, a temperature difference between an upper portion and a lower portion can be further approximated to a target value.

In a foot mode, in 14 is shown, and a foot-defroster mode, which in 15 is shown is a guide section 72 positioned so that warm air H1 from the passage 15 for warm air towards the defroster opening section 11 is deflected towards. Accordingly, a part of the warm air flows H1 rectilinear towards the defroster opening section 11 , and the rest of the warm air H1 flows towards the foot opening section 13 by moving along the guide section 72 turns. Accordingly, it is possible that, compared to the above first embodiment, in which the guide portion 72 is not present, more warm air the defroster opening section 11 reached. As a result, a temperature difference between an upper portion and a lower portion can be further approximated to the target value.

In the present embodiment, the guide portion is 72 arranged so that it extends from the end of the first flap opening section 55 at an outer peripheral wall 51 is provided toward a center position of a mode door 50 extends. However, it is sufficient if the guide section 72 towards an environment of the middle of the mode flap 50 extends.

Third embodiment

In the present embodiment, a shape and a location of the baffle portion and a shape of partition walls and a length of a guide portion 72 in a first room section 61 changed with respect to the counterparts in the above second embodiment. Other than the difference as above, the present embodiment has the same configuration as the above second embodiment.

As in the 16 . 17A . 17B . 17C and 18 are shown, all of a plurality of partitions 58 the shape of a disc and are as large as a first sidewall 52 and a second side wall 53 , As in the 17B and 18 is shown, sits a baffle section 73 to ends of the partitions 58 and is at an outermost circumferential position of a mode door 50 arranged. A leadership section 72 in a first room section 61 sits down to the dividing walls 58 away. The baffle sections 73 and the partitions 58 correspond respectively to the baffle sections 71 and the partitions 57 the above first and second embodiments.

As in 19 is shown, the baffle section 73 a mold on top of an air mixing damper 40 equivalent. That is, the baffle section 73 has a shape coming from one end 731 to the other end 732 is bent along a circumferential direction, which at an axial position 54a a rotary shaft 54 is centered. The guide section 72 in the first room section 61 is arranged so that it moves toward an environment of a center position of the mode door 50 extends (axial position 54a the rotary shaft). It should be noted, however, that the guiding section 72 the present embodiment is longer than the guide portion 72 the foregoing second embodiment is and extends from one end 551 a first flap opening section 55 in the circumferential direction up to a position over the axial position 54a the rotary shaft 54 extends beyond.

The baffle section 73 is arranged to function in predetermined modes in respective outlet modes. That is, in an in 19 shown front mode is the baffle section 73 positioned so that a stream of cold air C1 is not blocked by a passage 14 for cold air on a front opening section 12 heading. More precisely, the baffle section is located 73 at a position where the baffle section 73 opposite to a passage 15 for warm air. In other words, the baffle section 73 is located at a position where the baffle section 73 opposite to the air mix door 40 which is positioned to pass 14 opens for cold air.

In a defroster mode, the in 20 is shown, the baffle section 73 positioned so that a stream of warm air H1 not blocked by the passage 15 for warm air on a defroster opening section 11 heading. More precisely, the baffle section is located 73 at a position between the passage 14 for cold air and the defroster opening section 11 ,

In a bi-level mode, in 21 is shown, the baffle section 73 positioned so that a stream of cold air C1 from the passage 14 for cold air in the mode flap 50 into it and a stream of warm air H1 from the passage 15 for warm air in the mode flap 50 into it is not prevented. More precisely, the baffle section is located 73 at a position where the baffle section 73 opposite to the air mix door 40 which is positioned so that a flow of both the cold air C1 as well as the warm air H1 into the mode flap 50 into it is made possible.

In a foot mode, in 22 is shown, and in a foot defroster mode, in 23 is shown, the baffle section 73 positioned so that one between the air mix door 40 and an air conditioning enclosure 10 provided opening portion is closed and that it is to the passage 14 continues for cold air. More precisely, the baffle section 73 opposite and in close proximity to both the air mix door 40 as well as a wall 10a of the air conditioner housing 10 arranged. At the wall 10a of the air conditioner housing 10 it's about a section that goes along with the air mix door 40 forms an opening portion so that cold air can flow therethrough. The wall 10a of the air conditioner housing 10 extends along the air mix door 40 that she is using the air mix door 40 overlaps when the air mix door 40 positioned so that the passage 14 completely closed for cold air. Between the air mix door 40 and the baffle section 73 is provided a fine clearance, and between the wall 10a of the air conditioner housing 10 and the baffle section 73 is also provided a fine gap. Since a ventilation resistance of the fine gaps is high, cold air does not flow from the opening portion between the mixed air port 40 and the wall 10a of the air conditioner housing 10 in a first room section 61 into it, and the cold air flows instead into a second space section 62 into it.

Since the baffle section 71 In the above first embodiment, in the foot mode and in the foot defroster mode, located away from the air mix door, a small amount of cold air flows into the first space portion 61 into it.

In contrast, the baffle section 73 in the foot mode and in the foot defroster mode in the present embodiment in close proximity to the air mix door 40 arranged to prevent cold air from the opening between the air mix door 40 and the air conditioning case 10 in the first room section 61 flows into it. As a result, cold air does not flow into the first space section 61 into it, and only warm air flows into the first space section 61 into it. Accordingly, a temperature of air may be increased from the first space portion 61 into the defroster opening section 11 flows in, and as a result, a temperature of air passing through the defroster opening section 11 flows through, are increased compared to the above first embodiment. As a result, a temperature difference between an upper portion and a lower portion according to the present embodiment can be further approximated to a target value.

Fourth embodiment

The present embodiment has the same configuration as the above third embodiment, except that a shape of partition walls is changed from the shape in the above third embodiment.

As in the 24 and 25 is shown have all of the partitions 59 a substantially semicircular shape. As in 24 are shown are on a side of first flap opening sections 55 no partitions 59 available. The partitions 59 The present embodiment corresponds to the partitions 58 the above third embodiment.

More specifically, each of the plurality of partitions, as in FIG 26 Shown is a shape with a tendon 591 extending along a guide section 72 from one end 551 of the first flap opening section 55 on one side in a circumferential direction to one end 732 a baffle section 73 extends on the other side, and a bow 592 on that at an axial position 54a a rotary shaft 54 is centered. In a foot mode are the multiple partitions 59 positioned so that they are only present in a room closer to a passage 15 for warm air than at the guide section 72 inside an interior of the mode flap 50 lies. As in 25 shown are the partitions 59 configured in such a way that the tendons become 591 to the guide section 72 go on and get the bows 592 to the baffle section 73 continue.

Because the several partitions 58 In the above third embodiment, the shape of a disk is an entire interior of the mode door 50 in the first room sections 61 and the second room sections 62 divided. As a result, conditioned air flowing through the defroster opening section 11 and the foot opening section 13 flows through, in which 22 shown foot mode in an axial direction of the rotary shaft 54 an inhomogeneous temperature distribution, as warm air, in the first space section 61 prevails, and cold air in the second space section 62 prevails, in the axial direction of the rotary shaft 54 are alternately layered. As a result, blown air from a defroster outlet and blown air from a foot outlet have an inhomogeneous temperature distribution.

In contrast to this are the first room section 61 and the second space section 62 in the in the foot mode due to this, that the partition walls 59 are not present in the room inside the interior of the mode flap 50 closer to a defroster opening section 11 and a foot opening section 13 is less than the guide section 72 , As a result, it will allow warm air in the first room section 61 prevails, and cold air in the second space section 62 prevails, inside the mode flap 50 mix. Accordingly, a temperature distribution of conditioned air passing through the defroster opening section 11 and the foot opening section 13 flows through, to one in the axial direction of the rotary shaft 54 homogeneous distribution. The effect achieved in the foot mode as above can also be achieved in a foot defroster mode as well.

Even if the partitions 59 in the present embodiment are not present in the room, in the foot mode closer to the defroster opening section 11 and the foot opening section 13 is less than the guide section 72 , controls warm air from the first room section 61 due to a characteristic of its own linear motion on the defroster opening section 11 to. As a result, even in the present embodiment, a temperature difference between blast air from the defroster outlet and blast air from the foot outlet, that is, a temperature difference between an upper portion and a lower portion, can be reduced as in the above third embodiment.

Fifth embodiment

The present embodiment has the same configuration as the fourth embodiment above, except that on an outer peripheral wall 51 a mode flap 50 in addition to the configuration of the above fourth embodiment, a protrusion portion (a rib) 51c is provided.

The outer peripheral wall 51 has the protrusion portion 51c in a vicinity of a center of the outer peripheral wall 51 which has the cross section of an arc in a circumferential direction, from an inner surface of a base material 51a towards a middle of the mode flap 50 (to an axial position 54a the rotary shaft 54 ) sticks out. In a bi-level mode, in 28 is shown, the projecting portion 51c positioned so that a cold air C1a inside the mode flap 50 along the outer peripheral wall 51 towards a front opening section 12 flows, is deflected, leaving the cold air C1a towards a middle of the mode flap 50 flows. However, it can be seen that the projecting portion 51c at any position other than the center of the outer peripheral wall 51 may be provided, as long as the projecting portion 51c is able to handle the cold air C1a towards the middle of the mode flap 50 redirect.

The protrusion section 51c has a length from the inner surface of the base material 51a out, which is sufficiently low, so that a flow of a main stream (cold air C1 ) is not prevented in a front mode, which in 27 is shown on the front opening section 12 heading. More specifically, a position of a tip end of the protrusion portion is located 51c at a position near a virtual straight line (chord) VL in a cross section of the outer peripheral wall 51 who in 27 shown is an end 512 the outer peripheral wall 51 on one side in the circumferential direction and one end 552 a first flap opening section 55 connects on the same side in the circumferential direction. The position of the tip end of the protrusion portion 51c can something over the virtual straight line (sinew) VL lie.

Also in the present embodiment have a plurality of partitions 59 a semicircular shape, and a first space section 61 and a second space section 62 stand as in the above fourth embodiment due to the absence of the partition walls 59 in a room communicating with each other, closer to a defroster opening section 11 and a foot opening section 13 lies as a guide section 72 , The protrusion section 51c extends in an axial direction of the rotary shaft 54 through from a first side wall 52 up to a second side wall 53 the mode flap 50 in 24 ,

According to the present embodiment, which is configured as above, in a bi-level mode, which is shown in FIG 28 shown is from the cold air C1 that by a passage 14 for cold air has flowed into the interior, a cold air C1a that run along the outer peripheral wall 51 towards the front opening section 12 flows through, by means of the projecting portion 51c towards the middle of the mode flap 50 bent. Accordingly, mixing of cold air and warm air can be performed as compared with the above fourth embodiment in which the protruding portion 51c is absent, and as a result, a temperature difference between an upper portion and a lower portion can be further reduced.

The protrusion section 51c The present embodiment not only promotes mixing of cold air and warm air, but also also reinforces the base material 51a the outer peripheral wall 51 ,

In the present embodiment, the plurality of partition walls 59 a semicircular shape. Like the several partitions 58 In the above third embodiment, the plurality of partition walls 59 however, have the shape of a disc. In short, the present embodiment is also applicable to the above third embodiment. The present embodiment is further applicable to the above first and second embodiments.

Sixth embodiment

The present embodiment has a same configuration as the first embodiment except that a dimension of a defroster opening portion 11 is changed from the dimension in the above first embodiment.

As in 29 is shown has an air conditioning housing 10 an inner wall surface 10b in contact with an outer peripheral wall in a bi-level mode 51 a mode flap 50 manufactures. As well as in the 30 and 31 is shown, the air conditioner housing 10 a first inner wall surface 10c and a second inner wall surface 10d on, the a defroster opening section 11 form.

The first inner wall surface 10c sits down to the inner wall surface 10b towards and is located on a radially outer side of the inner wall surface 10b , As in 30 is shown, the first inner wall surface is located 10c in a foot mode opposite to the outer peripheral wall 51 , and therefore forms the first inner wall surface 10c together with the outer peripheral wall 51 an opening portion so that air flows therethrough. An in 30 shown opening width d1 , which is a distance between the first inner wall surface 10c and the outer peripheral wall 51 in a first room section 61 is greater than an opening width d2 in a second opening section 62 , in the 8B is shown.

The second inner wall surface 10d sits down to the first inner wall surface 10c away. As in 31 is shown, the second inner wall surface is located 10d in a foot defroster mode opposite to the outer peripheral wall 51 , and therefore forms the second inner wall surface 10d together with the outer peripheral wall 51 an opening portion so that air flows therethrough. An in 31 shown opening width d3 , which is a distance between the second inner wall surface 10d and the outer peripheral wall 51 in the first room section 61 is greater than an opening width d4 in the second room section 62 , in the 9B is shown.

As has been described, the air conditioner housing 10 configured in such a manner that in the foot mode and in the foot defroster mode, an opening area of the defroster opening portion 11 that with the first room section 61 is greater than an opening area of the defroster opening section 11 that is with the second space section 62 communicates. In a case where an air volume ratio of the defroster opening section 11 and the foot opening section 13 the same as the air volume ratio in the above first embodiment, becomes an opening area of the defroster opening portion 11 , the second room section 62 is set smaller, because an opening area of the defroster opening portion 11 that with the first room section 61 communicates, here is enlarged.

According to the present embodiment, more warm air is allowed to pass through the first space portion as compared with the above first embodiment in the foot mode and foot defroster mode 61 through the defroster opening section 11 flows into it. As a result, a temperature of air passing through the defroster opening section may be increased 11 flows through it. As a result, a temperature difference between an upper portion and a lower portion according to the present embodiment can be further approximated to a target value.

Seventh embodiment

The present embodiment has the same configuration as the above first embodiment except that a location for a foot opening portion 13 is changed from the location in the above first embodiment.

As in the 32 and 33 is shown has an air conditioning housing 10 a wall 10e on that the foot opening section 13 in a first room section 61 closes. As in the 8B and 9B is shown is a second space section 62 with the foot opening section 13 provided. That is, the air conditioning case 10 is with the foot opening section 13 so provided that it does not match the first room section 61 communicates, but that it is with the second space section 62 communicates. Accordingly, the foot opening section includes 13 several foot opening sections 13 acting in an axial direction of a mode flap 50 are arranged at predetermined intervals.

As a result, warm air can H1 in the first room section 61 into a foot mode and in a foot defroster mode only to a defroster opening section 11 be guided. Accordingly, according to the present embodiment, more warm air is allowed to pass through the first space portion as compared with the above first embodiment in the foot mode and foot defroster mode 61 through the defroster opening section 11 flows into it. Accordingly, a temperature of air passing through the defroster opening section may be increased 11 flows through it. As a result, a temperature difference between an upper portion and a lower portion according to the present embodiment can be further approximated to a target value.
