By the way, in recent years, miniaturization of vehicle air conditioners has been promoted. Particularly in a small car, since the space is limited, there is a great demand for downsizing of the air conditioner. For this reason, the volume in the air conditioning unit is restricted, and the cold air passage, the warm air passage, and the space for mixing the cold air and the hot air (air mix space) tend to be narrower than in the conventional case. As a result, the cold air and the warm air may not be sufficiently mixed and may be supplied indoors.

Therefore, the present invention provides a vehicle air conditioner capable of appropriately adjusting the temperature inside the vehicle even if the installation space is small.

According to the first aspect of the present invention, the vehicle air conditioner includes an evaporator that generates cold air by cooling the air, and a heater core that is disposed downstream of the evaporator and that warms the cold air to generate warm air. , An air supply passage arranged on the upstream side of the evaporator to supply the air to the evaporator, a cold air passage arranged on the upstream side of the heater core on the downstream side of the evaporator, the cold air flowing, A flow path for warm air, which is arranged on the downstream side of the heater core and blows out the hot air, and a flow path for cold air and a flow path for cold air, which are connected to the flow path for cold air and the flow path for warm air. A casing that is arranged on the downstream side of the flow channel for dividing the air mix space in which the cold air and the warm air are mixed, a duct that forms a flow channel that communicates with the air mix space, and the inside of the casing Between the heater core and the evaporator, a cold air communication port that connects the cold air flow path and the air mix space, and a hot air communication port that connects the hot air flow path and the air mix space are arranged. And a damper that adjusts the opening ratio of the cold air communication port and the warm air communication port by sliding and is provided as a member separate from the housing on the downstream side of the damper in the housing. A guide member that has a plurality of fins that extend from the hot air flow path toward the damper and the air mix space and that are spaced apart from each other in the width direction that intersects the direction in which the hot air flows.

According to this configuration, the vehicle air conditioner includes the guide member having the plurality of fins. The plurality of fins extend from the hot air flow path toward the air mix space. Therefore, the fins can disturb the flow of the cold air and the hot air to generate a complicated flow. Therefore, mixing of cold air and warm air can be promoted. Further, since the plurality of fins are provided so as to sandwich the warm air from the width direction, it is possible to suppress the warm air from spreading to the outer side in the width direction toward the air mix space, and the flow velocity of the warm air is increased. As a result, the penetrating force of the warm air with respect to the cool air flowing in the air mix space is increased, and the warm air is not blown off by the cool air. Therefore, warm air and cold air can be sufficiently mixed.

Further, in the above vehicle air conditioner, the guide member may further include a base portion that extends in the width direction and is detachably supported by the housing, and that supports the plurality of fins. ..

According to this structure, the guide member is detachably supported by the base portion with respect to the housing. Accordingly, when the housing is formed by injection molding of resin, for example, the mold can be manufactured without considering the shape of the guide member. Furthermore, since there is no restriction imposed by the mold, the shape of the guide member itself can be made flexible.

Further, in the above vehicle air conditioner, the guide member may further include a base portion that extends in the width direction and is integrally provided in the housing, and that detachably supports the plurality of fins. Good.

According to this configuration, the plurality of fins are detachably attached to the housing by the base portion integrated with the housing. This makes it possible to easily change the shape, installation direction, installation position, etc. of the plurality of fins in accordance with the flow of warm air.

Further, in the above vehicle air conditioner, at least one fin of the plurality of fins may be inclined and extended toward one side in the width direction toward the damper.

According to this configuration, at least one fin extends obliquely toward one side in the width direction toward the damper. Thereby, the warm air can be guided to one side in the width direction along the fins. As a result, the flow can be such that the cold air and the hot air are exchanged, and the mixing of the hot air and the cold air can be promoted.

Further, in the above vehicle air conditioner, the plurality of fins may extend so as to incline so as to approach each other in the width direction toward the damper.

According to this configuration, the plurality of fins extend obliquely so as to be close to each other. Thereby, the space (flow path) between the fins becomes narrower toward the downstream side of the flow of the warm air, and the flow velocity of the warm air passing through the space between the fins can be increased. As a result, the mixing of warm air and cold air can be further promoted.

Further, in the above vehicle air conditioner, all of the plurality of fins may be inclined and extended toward one side in the width direction toward the damper.

According to this structure, the plurality of fins extend toward the damper while being inclined in the same direction. Thereby, the warm air can be smoothly guided to the one side in the width direction by the fins. As a result, the flow can be such that the cold air and the hot air are exchanged, and the mixing of the hot air and the cold air can be promoted.

According to the above vehicle air conditioner, it is possible to properly control the temperature inside the vehicle even if the installation space is small.

And a flow path 11H (duct) for the differential and the face, a face outlet 11I, and a differential outlet 11L.

The blower housing space 11A is a space for housing the blower 13. The air supply channel 11B communicates with the blower housing space 11A and the evaporator housing space 11C. The air supply channel 11B is arranged on the upstream side of the evaporator 15.
The evaporator accommodation space 11C is arranged on the downstream side of the air supply channel 11B. The evaporator housing space 11C is a space for housing the evaporator 15.

The cold air flow passage 11D is arranged on the downstream side of the evaporator housing space 11C. The cold air flow passage 11D communicates with the evaporator accommodation space 11C and the heater core accommodation space 11E. Among the outlets of the cold air flow passage 11D, an upper region of the slide damper 19 (described later) is a cold air communication port 51, and a lower region thereof is a warm air communication port 52.

The heater core accommodation space 11E is arranged on the downstream side of the cold air flow passage 11D. The heater core housing space 11E is a space for housing the heater core 17.

The hot air flow passage 11F is arranged on the downstream side of the heater core housing space 11E and is connected to the heater core housing space 11E. The hot air generated by the heater core 17 is blown out into the hot air flow passage 11F. In the following description, the direction intersecting (orthogonal to) the warm air flow direction may be referred to as the width direction D1. Further, a direction orthogonal to the width direction D1 in the horizontal plane may be referred to as a front-back direction D2.

The air mix space 11G is arranged downstream of the cold air flow passage 11D and the warm air flow passage 11F. When the slide damper body 19B (one of the components of the slide damper 19) is in the position shown in FIG. 1, the air mix space 11G is cooled by the cold air communication port 51 and the warm air communication port 52 described above. The flow passage 11D and the hot air flow passage 11F communicate with each other.

In the state where the slide damper body 19B is in the position shown in FIG. 1, the cold air that has passed through the cold air flow passage 11D and the hot air that has passed through the hot air flow passage 11F are supplied to the air mix space 11G. In the air mix space 11G, cold air and warm air are mixed to generate air having a desired temperature.

When the slide damper body 19B slides downward and the cool air from the evaporator 15 is not supplied to the heater core 17, only the cool air is supplied to the air mix space 11G.

The rotary damper 28 is arranged in the air mix space 11G. The rotary damper 28 adjusts the opening degree of the inlets of the differential and face flow channels 11H, the front foot flow channel (not shown), and the rear foot flow channel (not shown). The rotary damper 28 includes a rotating shaft 60 and a damper body 61 that rotates together with the rotating shaft 60.

The differential and face flow passage 11H is arranged above the air mix space 11G. When the rotary damper 28 is in the position shown in FIG. 1, the differential and face flow passage 11H is in communication with the air mix space 11G. In this state, the air that has passed through the air mix space 11G is supplied to the differential and face flow paths 11H. When the rotary damper 28 blocks the inlet of the differential and face flow passage 11H, the air that has passed through the air mix space 11G is not supplied to the differential and face flow passage 11H.

The face outlet 11I is arranged downstream of the differential and face flow passage 11H and communicates with the differential and face flow passage 11H.

The differential air outlet 11L is arranged downstream of the differential and face flow passage 11H and communicates with the differential and face flow passage 11H. The differential outlet 11L is arranged closer to the blower 13 than the face outlet 11I.

The blower 13 is arranged in the blower housing space 11A. The blower 13 supplies air to the air supply channel 11B. The evaporator 15 is arranged in the evaporator housing space 11C. The evaporator 15 cools the air supplied from the blower 13 to generate cold air. The generated cold air flows through the cold air flow passage 11D.

The heater core 17 is arranged in the heater core housing space 11E. When the cool air is supplied from the evaporator 15, the heater core 17 warms the cool air to generate hot air. The generated hot air flows through the hot air flow passage 11F.

The slide damper 19 is arranged between the evaporator 15 and the heater core 17. The slide damper 19 has a rotating shaft 19A and a slide damper body 19B. The rotary shaft 19A is a gear that is rotatable around its axis. A plurality of teeth are formed in the circumferential direction of the rotary shaft 19A.

The slide damper body 19B is arranged closer to the heater core 17 than the rotary shaft 19A. The slide damper body 19B has a rack gear that engages with the teeth of the rotating shaft 19A. In the state shown in FIG. 1, when the rotary shaft 19A rotates clockwise, the slide damper body 19B slides (moves) downward. As a result, the cold air communication port 51 is opened more than the warm air communication port 52. On the other hand, when the rotary shaft 19A rotates counterclockwise, the slide damper body 19B slides (moves) upward. As a result, the hot air communication port 52 is opened to a greater extent than the cold air communication port 51. That is, the slide damper 19 slides to adjust the ratio of the opening degrees of the cold air communication port 51 and the warm air communication port 52.

The diff and face damper 31 is rotatably provided inside the housing 11 located between the face air outlet 11I and the diff air outlet 11L. The differential and face damper 31 is a damper for adjusting the opening of the face outlet 11I and the differential outlet 11L.

The guide member 40 is arranged on the downstream side of the hot air flow path. The guide member 40 is provided for rectifying the hot air flowing out from the hot air flow path. The guide member 40 has a base portion 41 and a plurality of fins 42.

The base portion 41 is a plate-shaped member that is arranged slightly above the upper end portion of the heater core 17 with a space therebetween. As shown in FIG. 2, the base portion 41 includes a first support portion 41A provided on the other side in the front-rear direction D2, a second support portion 41C provided on one side in the front-rear direction D2, and these first support portions 41A. And a base portion main body 41B extending in the front-rear direction D2 between the second support portion 41C. The first support portion 41A has a triangular cross section as the dimension in the front-rear direction D2 gradually decreases from the upper side to the lower side. The second support portion 41C has a triangular cross-section as the dimension in the front-rear direction D2 gradually decreases from the lower side to the upper side.

The first support portion 41A is provided with a pin 41D extending along the width direction D1. The second support portion 41C is similarly provided with a pin 41E extending along the width direction D1. The guide member 40 is detachably supported in the housing 11 by inserting the pins 41D and 41E into holes (not shown) formed in the inner surface of the housing 11. One surface of the base portion main body 41B faces the air mix space 11G. On the other hand, the other surface of the base portion main body 41B faces the heater core 17 side.

As shown in FIGS. 1 and 2, a plurality of fins 42 are integrally provided on one surface of the base portion 41 (base portion main body 41B). Each fin 42 has a rectangular plate shape protruding from the base portion 41 toward the air mix space 11G side (upper side) and the slide damper 19 side (front side). However, the shape of the fin 42 is not limited to a rectangle. In the present embodiment, the protruding height of each fin 42 gradually increases from the warm air flow path side toward the heater core housing space side. Further, as shown in FIG. 2, when the slide damper body 19B is at the lowest position (that is, the warm air flow passage 11F is closed by the slide damper body 19B), each fin 42 is attached to the slide damper body 19B. Of the upper end portion of the upper end portion (position shown by a chain line in FIG. 2) slightly upward. That is, the upper ends of the fins 42 are arranged at the midpoint height of the cold air communication port 51 below the air mix space 11G. Therefore, the fins 42 are provided so as not to block the cold air communication port 51 in the entire area in the height direction, but to block only a part in the height direction. Further, the front end portion of each fin 42 is arranged at a position away from the cold air communication port 51 rearward.

As shown in FIG. 3, the guide member 40 according to the present embodiment has four fins 42. These four fins 42 are arranged at intervals in the width direction D1. The two fins 42 located on one side in the width direction D1 incline from one side in the width direction D1 toward the other side as going from one side in the front-rear direction D2 to the other side (that is, the slide damper 19 side). Is extended. The two fins 42 located on the other side in the width direction D1 extend from the other side in the width direction D1 to the one side while inclining from the other side in the front-rear direction D2 toward the other side. In other words, the pair of fins 42 are arranged so as to gradually approach each other from one side in the front-rear direction D2 toward the other side.

In the present embodiment, the guide member 40 is formed as a separate member with respect to the housing 11. That is, the guide member 40 is detachably attached to the housing 11. In the above description, the example in which the plurality of fins 42 are integrally formed with the base portion 41 has been described. However, it is also possible to attach and detach only the fins 42 to and from the base portion 41 that is integrally provided in the housing 11, and to attach and detach the base portion 41 to and from the housing 11, and The fin 42 may be detachable from the base portion 41.

Then, operation|movement of the vehicle air conditioner 10 which concerns on this embodiment is demonstrated. When operating the vehicle air conditioner 10, first, the blower 13 is operated. With the operation of the blower 13, air flows through the air supply flow path 11B. The air that has passed through the air supply channel 11B comes into contact with the evaporator 15 to be heat-exchanged into cold air, and flows into the cold air channel 11D. In the state where the slide damper body 19B is in the position shown in FIG. 1, a part of the air that has flowed into the cold air flow passage 11D passes below the slide damper body 19B (the warm air communication port 52) and the heater core accommodation space 11E. Flow into. The air flowing into the heater core housing space 11E comes into contact with the heater core 17 and is heat-exchanged to become warm air. The warm air flows toward the air mix space 11G described above through the hot air flow passage 11F. On the other hand, the remaining components of the air that has flowed into the cold air flow passage 11D pass above the slide damper body 19B (cold air communication port 51) toward the air mix space 11G. That is, in the air mix space 11G, the cool air and the warm air are mixed at a ratio according to the position of the slide damper body 19B.

Here, in recent years, downsizing of air conditioners has been promoted. Particularly in a small car, since the space is limited, there is a great demand for downsizing of the air conditioner. Therefore, the volume in the air conditioning unit is restricted, and the cold air flow passage 11D, the warm air flow passage 11F, and the space (air mix space 11G) for mixing the cold air and the warm air are more than conventional. It tends to become narrower. As a result, the cold air and the warm air may not be sufficiently mixed and may be supplied indoors.

In particular, in the above vehicle air conditioner, the cold air reaches the air mix space 11G directly from the cold air flow passage 11D, whereas the hot air flows in the cold air flow passage 11D, the heater core 17, and the hot air flow passage 11F. Through to reach the air mix space 11G. That is, since the hot air flow passage 11F has a larger pressure loss in the flow passage than the cold air flow passage 11D, the flow velocity of the hot air may decrease. When the flow velocity of the warm air decreases, when the cold air is mixed in the air mixing space 11G, the relatively high speed cold air blows the warm air away, and the two cannot be sufficiently mixed. As a result, it may be difficult to precisely control the temperature.

However, in the vehicle air conditioner according to the present embodiment, the guide member 40 having the plurality of fins 42 is provided on the downstream side of the hot air flow passage 11F. The plurality of fins 42 extend from the hot air flow path toward the air mix space. Therefore, the fins 42 can disturb the flow of the cold air and the hot air to generate a complicated flow. Therefore, mixing of cold air and warm air can be promoted. Further, since the plurality of fins 42 are provided so as to sandwich the warm air from the width direction D1, it is possible to suppress the warm air from spreading to the outside in the width direction D1 toward the air mix space 11G, and the flow velocity of the warm air is increased. .. As a result, the penetrating force of the warm air with respect to the cool air flowing in the air mix space is increased, and the warm air is not blown off by the cool air. Therefore, warm air and cold air can be sufficiently mixed.

Furthermore, according to the above configuration, the guide member 40 is detachably supported by the base portion 41 with respect to the housing 11. Accordingly, when the housing 11 is formed by injection molding of resin, for example, a mold can be manufactured without considering the shape of the guide member 40. Furthermore, since the guide member 40 is configured to be removable, the shape of the guide member 40 itself can be made flexible.

In addition, as described above, when the plurality of fins 42 are detachably provided to the base portion 41 integrated with the housing 11, the plurality of fins 42 are detachably provided to the housing 11. Can easily change the shape, the installation direction, the installation position, etc. of the plurality of fins 42 according to the flow of warm air.

Furthermore, according to the above configuration, the plurality of fins 42 extend so as to be close to each other. As a result, the space (flow path) between the fins 42 becomes narrower toward the downstream side of the flow of the warm air, and the flow velocity of the warm air passing through the space between the fins 42 can be increased. As a result, the mixing of warm air and cold air can be further promoted.

Further, according to the above configuration, the upper end of each fin 42 is arranged at a midway height position of the cold air communication port 51 below the air mix space 11G, whereby the cool air in the upper part of the cold air communication port 51 is cooled. In the area near the communication port 51, it is possible to suppress the cold air from interfering with the fins 42 to the minimum, and it is possible to ensure a suitable distribution of the cold air in this area. This suppresses noise and vibration particularly during the maximum cooling operation (when the opening degree of the cold air communication port 51 is maximized), and suppresses the efficiency decrease of the entire device due to the increase of the pressure loss. Further, since the front end portion of each fin 42 is arranged at a position rearward with respect to the cold air communication port 51, the circulation of the cool air is not significantly hindered.

The first embodiment of the present invention has been described above. Note that various changes and modifications can be made to the above configuration without departing from the spirit of the present invention. For example, in the above embodiment, the example in which the number of the fins 42 of the guide member 40 is four has been described. However, the number of fins 42 is not limited to four, and can be changed appropriately according to the specifications and design. For example, as shown in FIG. 4, it is possible to provide only two fins 42.

[Second embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. As shown in FIG. 5, in the present embodiment, the guide member 40 has only two fins 42B, and these fins 42B extend in the same direction as each other. Specifically, each fin 42B extends from one side in the front-rear direction D2 toward the other side while inclining from the other side in the width direction D1 toward the one side. It suffices that the fins 42B extend obliquely in the same direction as each other, may extend in parallel with each other, and may have different inclination angles with respect to the width direction D1.

According to this structure, the plurality of fins 42B extend toward the slide damper 19 while being inclined in the same direction. Thereby, the warm air can be smoothly guided to the one side in the width direction D1 by the fins 42B. As a result, the flow can be such that the cold air and the hot air are exchanged, and the mixing of the hot air and the cold air can be promoted.

The second embodiment of the present invention has been described above. Note that various changes and modifications can be made to the above configuration without departing from the spirit of the present invention. For example, in the above embodiment, the example in which the number of the fins 42B of the guide member 40 is two has been described. However, the number of the fins 42B is not limited to two, and can be appropriately changed according to the specifications and the design. Further, the fins 42B may extend obliquely from one side in the width direction D1 to the other side from the one side to the other side in the front-rear direction D2 contrary to the above case.

[Third embodiment]
Subsequently, a fourth embodiment of the present invention will be described with reference to FIG. The same components as those in the above-described embodiments are designated by the same reference numerals, and detailed description thereof will be omitted. As shown in FIG. 6, the guide member 40 has only two fins 42C and 42D, and these fins 42C and 42D extend in mutually different directions. The fins 42C located on the other side in the width direction D1 extend from the other side in the width direction D1 toward the one side from the one side in the front-rear direction D2 toward the other side. On the other hand, the fin 42D located on one side in the width direction D1 extends in the front-rear direction D2.

With this configuration, the plurality of fins 42C and 42D extend in the same direction toward the damper. Thereby, the warm air can be smoothly guided. Further, since the two fins 42C and 42D are arranged so as to gradually approach each other toward the other side in the front-rear direction D2, the flow velocity of the warm air can be increased. As a result, the mixing of warm air and cold air can be promoted.

The third embodiment of the present invention has been described above. Note that various changes and modifications can be made to the above configuration without departing from the spirit of the present invention. For example, in the above embodiment, the example in which the number of the fins 42C and 42D of the guide member 40 is two has been described. However, the number of fins 42C and 42D is not limited to two, and can be appropriately changed according to specifications and design.

In the above vehicle air conditioner, the temperature inside the vehicle can be properly adjusted even if the installation space is small.

According to the first aspect of the present invention, the vehicle air conditioner includes an evaporator that generates cold air by cooling the air, and a heater core that is disposed downstream of the evaporator and that warms the cold air to generate warm air. , An air supply passage arranged on the upstream side of the evaporator to supply the air to the evaporator, a cold air passage arranged on the upstream side of the heater core on the downstream side of the evaporator, the cold air flowing, A flow path for warm air, which is arranged on the downstream side of the heater core and blows out the hot air, and a flow path for cold air and a flow path for cold air, which are connected to the flow path for cold air and the flow path for warm air. A casing that is arranged on the downstream side of the flow channel for dividing the air mix space in which the cold air and the warm air are mixed, a duct that forms a flow channel that communicates with the air mix space, and the inside of the casing Between the heater core and the evaporator, a cold air communication port that connects the cold air flow path and the air mix space, and a hot air communication port that connects the hot air flow path and the air mix space are arranged. And a damper that adjusts the opening ratio of the cold air communication port and the warm air communication port by sliding and is provided as a member separate from the housing on the downstream side of the damper in the housing. A guide member extending from the hot air flow path toward the damper and the air mix space, the guide member having a plurality of fins arranged apart from each other in a width direction intersecting a direction in which the hot air flows , At least one fin of the plurality of fins that extend inclined toward the one side in the width direction toward the free damper.

According to this configuration, the vehicle air conditioner includes the guide member having the plurality of fins. The plurality of fins extend from the hot air flow path toward the air mix space. Therefore, the fins can disturb the flow of the cold air and the hot air to generate a complicated flow. Therefore, mixing of cold air and warm air can be promoted. Further, since the plurality of fins are provided so as to sandwich the warm air from the width direction, it is possible to suppress the warm air from spreading to the outer side in the width direction toward the air mix space, and the flow velocity of the warm air is increased. As a result, the penetrating force of the warm air with respect to the cold air flowing through the air mix space is increased, and the warm air is not blown away by the cold air. Therefore, the warm air and the cold air can be sufficiently mixed.
Further, according to this configuration, at least one fin extends obliquely toward one side in the width direction toward the damper. Thereby, the warm air can be guided to one side in the width direction along the fins. As a result, the flow can be such that the cold air and the hot air are exchanged, and the mixing of the hot air and the cold air can be promoted.
