Disclosure of Invention
Technical problem to be solved by the invention
In recent years, miniaturization of air conditioning apparatuses for vehicles is advancing. In particular, since a space for a small car is limited, there is a great demand for miniaturization of an air conditioner. Therefore, the volume within the air conditioning unit is limited, and the above-described cool air passage, warm air passage, and space for mixing cool air and warm air (gas mixing space) tend to be narrower than before. As a result, cold air and warm air may not be sufficiently mixed and supplied into the room.
Accordingly, the present invention provides a vehicle air conditioner that can appropriately adjust the temperature in a vehicle even if the installation space is small.
Means for solving the technical problems
According to a first aspect of the present invention, an air conditioner for a vehicle includes: a carburetor for generating cool air by cooling air; a heater core disposed at a downstream side of the carburetor and generating warm air by heating the cool air; a frame that divides an air supply flow path that is disposed on an upstream side of the carburetor to supply the air to the carburetor, a cool air flow path that is disposed on a downstream side of the carburetor and on an upstream side of the heater core to allow the cool air to flow therethrough, a warm air flow path that is disposed on a downstream side of the heater core to blow out the warm air, and a gas mixing space that is connected to the cool air flow path and the warm air flow path and that is disposed on a downstream side of the cool air flow path and the warm air flow path and that mixes the cool air and the warm air; a conduit forming a flow path communicating with the gas mixing space; a damper that is disposed between the heater core and the carburetor in the housing over a cool air communication port and a warm air communication port, and that adjusts a ratio of opening degrees of the cool air communication port and the warm air communication port by sliding, the cool air communication port connecting the cool air flow path and the gas mixing space, and the warm air communication port connecting the warm air flow path and the gas mixing space; and a guide member that is provided on a downstream side of the damper in the housing as a member separate from the housing, extends from the warm air flow path toward the damper and the gas mixing space, and has a plurality of blades that are arranged apart from each other in a width direction intersecting a direction in which the warm air flows.
According to this configuration, the vehicle air conditioner includes the guide member having the plurality of blades. The plurality of blades extend from the warm air flow path toward the gas mixing space. Therefore, the flow of cool air and warm air can be disturbed by the blades, and a complicated flow can be generated. This can promote mixing of cool air and warm air. Further, since the plurality of blades are provided so as to sandwich the warm air from the width direction, the flow velocity of the warm air can be prevented from being increased by suppressing the spread of the warm air to the outside in the width direction as the warm air goes toward the gas mixing space. As a result, the penetration force of the warm air flowing through the gas mixture space with respect to the cool air increases, and the warm air is not blown away by the cool air. This enables the warm air and the cool air to be sufficiently mixed.
The vehicle air conditioner may be as follows: the guide member extends in the width direction and is detachably supported by the frame, and further has a base portion that supports the plurality of blades.
According to this structure, the guide member is detachably supported by the frame body through the base portion. Thus, for example, when the frame is formed by injection molding using a resin, the mold can be manufactured regardless of the shape of the guide member. Further, since the guide member is not limited by the mold, the shape of the guide member itself can be flexibly changed.
The vehicle air conditioner may be as follows: the guide member extends in the width direction and is integrally provided to the frame, and further has a base portion that detachably supports the plurality of blades.
According to this structure, the plurality of blades are detachably provided to the housing through the base portion integrated with the housing. This makes it possible to easily change the shape, the installation direction, the installation position, and the like of the plurality of blades in accordance with the flow of warm air.
The vehicle air conditioner may be as follows: at least one of the plurality of blades extends obliquely toward one side in the width direction as it faces the damper.
According to this structure, at least one vane extends obliquely toward one side in the width direction as it goes toward the damper. This makes it possible to guide warm air along the blades to one side in the width direction. As a result, the cold air and the warm air can be alternately flowed, and the mixing of the warm air and the cold air can be promoted.
The vehicle air conditioner may be as follows: the plurality of blades extend obliquely toward the damper so as to approach each other in the width direction.
According to this structure, the plurality of blades extend obliquely in such a manner as to be close to each other. Thus, the space (flow path) between the blades becomes narrower as going toward the downstream side of the flow of warm air, and the flow rate of warm air flowing through the space between the blades can be increased. As a result, mixing of warm air and cool air can be further promoted.
The vehicle air conditioner may be as follows: the plurality of blades each extend obliquely toward one side in the width direction as it goes toward the damper.
According to this structure, the plurality of blades extend obliquely toward the damper in the same direction as each other. This allows warm air to be smoothly guided to one side in the width direction by the blades. As a result, the cold air and the warm air can be alternately flowed, and the mixing of the warm air and the cold air can be promoted.
Effects of the invention
According to the air conditioner for a vehicle described above, even if the installation space is small, the temperature in the vehicle can be appropriately adjusted.

Detailed Description
First embodiment
A first embodiment of the present invention will be described with reference to fig. 1 to 3. The vehicle air conditioner 10 according to the present embodiment includes a housing 11, a blower 13, a carburetor 15, a heater core 17, a slide damper 19, a rotary damper 28, a front-blowing window, a face-blowing damper 31, and a guide member 40.
The housing 11 defines a blower housing space 11A, an air supply passage 11B, a carburetor housing space 11C, a cool air passage 11D, a heater core housing space 11E, a warm air passage 11F, a gas mixing space 11G, a front blowing window, a face blowing passage 11H (duct), a face blowing air outlet 11I, and a front blowing window air outlet 11L.
The blower housing space 11A is a space for housing the blower 13. The air supply flow path 11B communicates with the blower accommodating space 11A and the carburetor accommodating space 11C. The air supply flow path 11B is disposed upstream of the carburetor 15.
The carburetor accommodation space 11C is disposed downstream of the air supply flow path 11B. The carburetor accommodation space 11C is a space for accommodating the carburetor 15.
The cool air flow path 11D is disposed downstream of the carburetor accommodation space 11C. The cool air flow path 11D communicates with the carburetor accommodation space 11C and the heater core accommodation space 11E. In the outlet of the cool air flow path 11D, an upper region of the slide damper 19 (described later) is a cool air communication port 51, and a lower region thereof is a warm air communication port 52.
The heater core accommodating space 11E is disposed downstream of the cooling air flow path 11D. The heater core accommodation space 11E is a space for accommodating the heater core 17.
The warm air flow path 11F is disposed downstream of the heater core accommodating space 11E and is connected to the heater core accommodating space 11E. The warm air generated by the heater core 17 is blown out to the warm air flow path 11F. In the following description, a direction intersecting (orthogonal to) the flow direction of the warm air is often referred to as a width direction D1. The direction orthogonal to the width direction D1 in the horizontal plane is often referred to as the front-rear direction D2.
The gas mixing space 11G is disposed downstream of the cool air flow path 11D and the warm air flow path 11F. When the slide damper main body 19B (one of the constituent elements of the slide damper 19) is positioned at the position shown in fig. 1, the gas mixing space 11G communicates with the cool air flow path 11D via the cool air communication port 51 and the warm air communication port 52.
In a state where the slide damper main body 19B is located at the position shown in fig. 1, the cool air flowing through the cool air flow path 11D and the warm air flowing through the warm air flow path 11F are supplied to the gas mixture space 11G. In the gas mixing space 11G, cool air is mixed with warm air and air reaching a desired temperature is generated.
In addition, only the cool air is supplied to the gas mixing space 11G in a state in which the slide damper main body 19B slides downward without supplying the cool air from the carburetor 15 to the heater core 17.
The rotary damper 28 is disposed in the gas mixing space 11G. The rotary damper 28 adjusts the opening degrees of the inlets of the front-blowing window and the face-blowing channel 11H, the opening degrees of the front-foot channel (not shown) and the rear-foot channel (not shown). The rotary damper 28 has a rotary shaft 60 and a damper main body 61 that rotates together with the rotary shaft 60.
The front blowing window and the face blowing passage 11H are disposed above the gas mixing space 11G. In a state where the rotary damper 28 is located at the position shown in fig. 1, the front blowing window and the face blowing flow path 11H communicate with the gas mixing space 11G. In this state, air flowing through the gas mixing space 11G is supplied to the front blowing window and the face blowing flow path 11H. When the rotary damper 28 closes the inlet of the front-blowing window and the face-blowing passage 11H, the air flowing through the gas mixing space 11G cannot be supplied to the front-blowing window and the face-blowing passage 11H.
The face blowing air outlet 11I is disposed downstream of the front blowing window and the face blowing flow path 11H, and communicates with the front blowing window and the face blowing flow path 11H.
The front-blowing window air outlet 11L is disposed downstream of the front-blowing window and the face-blowing flow path 11H, and communicates with the front-blowing window and the face-blowing flow path 11H. The front-blowing window air outlet 11L is disposed closer to the blower 13 than the face-blowing air outlet 11I.
The blower 13 is disposed in the blower accommodation space 11A. The blower 13 supplies air to the air supply passage 11B. The carburetor 15 is disposed in the carburetor accommodation space 11C. The carburetor 15 cools the air supplied from the blower 13, thereby generating cool air. The generated cool air flows through the cool air flow path 11D.
The heater core 17 is disposed in the heater core accommodating space 11E. The heater core 17 heats cold air when the cold air is supplied from the carburetor 15, thereby generating warm air. The generated warm air flows through the warm air flow path 11F.
The slide damper 19 is disposed between the carburetor 15 and the heater core 17. The slide damper 19 has a rotation shaft 19A and a slide damper main body 19B. The rotation shaft 19A is a gear rotatable about an axis. A plurality of teeth are formed in the circumferential direction of the rotation shaft 19A.
The slide damper main body 19B is disposed closer to the heater core 17 than the rotation shaft 19A. The slide damper main body 19B has a rack engaged with the teeth of the rotation shaft 19A. In the state shown in fig. 1, when the rotation shaft 19A rotates rightward, the slide damper main body 19B slides (moves) downward. As a result, the cool air communication port 51 is opened larger than the warm air communication port 52. On the other hand, when the rotation shaft 19A rotates leftward, the slide damper main body 19B slides (moves) upward. As a result, the warm air communication port 52 is opened larger than the cool air communication port 51. That is, the sliding damper 19 adjusts the ratio of the opening degrees of the cool air communication port 51 and the warm air communication port 52 by sliding.
The front-blowing window and the face-blowing damper 31 are provided rotatably inside the housing 11 located between the face-blowing air outlet 11I and the front-blowing window air outlet 11L. The front-blowing window and front-blowing damper 31 is a damper for adjusting the opening degrees of the front-blowing air outlet 11I and the front-blowing window air outlet 11L.
The guide member 40 is disposed downstream of the warm air flow path. The guide member 40 is provided to rectify the warm air flowing out of the warm air flow path. The guide member 40 has a base portion 41 and a plurality of blades 42.
The base portion 41 is a plate-like member disposed slightly above the upper end portion of the heater core 17. As shown in fig. 2, the base portion 41 includes: the first support portion 41A provided on the other side in the front-rear direction D2; a second support portion 41C provided on the front-rear direction D2 side; and a base body 41B extending in the front-rear direction D2 between the first support portion 41A and the second support portion 41C. The first support portion 41A has a triangular cross section by gradually decreasing in size in the front-rear direction D2 as it goes from above to below. The second support portion 41C has a triangular cross section by gradually decreasing in size in the front-rear direction D2 as it goes from below to above.
The first support portion 41A is provided with a pin 41D extending in the width direction D1. The second support portion 41C is also provided with a pin 41E extending in the width direction D1. These pins 41D and 41E are inserted into holes (not shown) formed in the inner surface of the housing 11, whereby the guide member 40 is detachably supported in the housing 11. The side of the base body 41B faces the gas mixing space 11G. On the other hand, the other side of the base body 41B faces the heater core 17 side.
As shown in fig. 1 and 2, a plurality of blades 42 are integrally provided on one side surface of the base portion 41 (base portion main body 41B). Each vane 42 has a rectangular plate shape protruding from the base 41 toward the gas mixing space 11G side (upper side) and the slide damper 19 side (front side). The shape of the blade 42 is not limited to a rectangular shape. In the present embodiment, the protruding height of each vane 42 gradually increases from the warm air flow path side toward the heater core accommodating space side. As shown in fig. 2, in a state where the sliding damper main body 19B is located at the lowermost position (i.e., in a state where the warm air flow path 11F is blocked by the sliding damper main body 19B), each vane 42 protrudes slightly above the height (position indicated by a broken line in fig. 2) of the upper end portion of the sliding damper main body 19B. That is, the upper ends of the blades 42 are disposed at the intermediate level of the cold air communication port 51 below the gas mixing space 11G. Thus, each of the blades 42 is provided so as not to block the cold air communication port 51 in the entire height direction but to block only a part of the height direction. The front end of each vane 42 is disposed at a position spaced rearward from the cool air communication port 51.
As shown in fig. 3, the guide member 40 according to the present embodiment has 4 blades 42. The 4 blades 42 are arranged at intervals in the width direction D1. The 2 blades 42 located on one side in the width direction D1 extend obliquely from one side toward the other side in the width direction D1 as one side toward the other side in the front-rear direction D2 (i.e., the sliding damper 19 side). The 2 blades 42 located on the other side in the width direction D1 extend obliquely from the other side in the width direction D1 toward one side as they go from one side toward the other side in the front-rear direction D2. In other words, each pair of blades 42 is arranged so as to gradually approach from one side toward the other side in the front-rear direction D2.
In the present embodiment, the guide member 40 is formed as a member separate from the housing 11. That is, the guide member 40 is detachably attached to the housing 11. In the above description, an example in which the plurality of blades 42 are integrally formed on the base portion 41 has been described. Therefore, not only the respective blades 42 but also the base portion 41 can be detached from the base portion 41 integrally provided to the housing 11, and the blades 42 can also be detached from the base portion 41.
Next, the operation of the vehicle air conditioner 10 according to the present embodiment will be described. When the vehicle air conditioner 10 is operated, the blower 13 is first activated. With the activation of the blower 13, air flows through the air supply passage 11B. The air flowing through the air supply passage 11B contacts the carburetor 15, and is heat-exchanged to become cool air, and flows into the cool air passage 11D. In a state where the slide damper main body 19B is located at the position shown in fig. 1, a part of the air flowing into the cool air flow path 11D flows through the lower side (warm air communication port 52) of the slide damper main body 19B and flows into the heater core accommodating space 11E. The air flowing into the heater core accommodating space 11E contacts the heater core 17, and exchanges heat to become warm air. The warm air passes through the warm air passage 11F and is directed to the gas mixing space 11G. On the other hand, the surplus air component after flowing into the cool air flow path 11D flows through the upper side (cool air communication port 51) of the slide damper main body 19B toward the gas mixing space 11G. That is, in the gas mixing space 11G, the cool air and the warm air are mixed in a ratio corresponding to the position of the sliding damper main body 19B.
Accordingly, miniaturization of air conditioning apparatuses has been advanced in recent years. In particular, since a space for a small car is limited, there is a great demand for miniaturization of an air conditioner. Therefore, the volume in the air conditioning unit is limited, and the above-described cool air flow path 11D, warm air flow path 11F, and space for mixing cool air and warm air (gas mixing space 11G) tend to be narrower than before. As a result, cold air and warm air may not be sufficiently mixed and supplied into the room.
In particular, in the above-described vehicle air conditioner, the cool air directly reaches the gas mixture space 11G from the cool air flow path 11D, and the warm air reaches the gas mixture space 11G through the cool air flow path 11D, the heater core 17, and the warm air flow path 11F. That is, since the pressure loss in the hot air flow path 11F is larger than that in the cold air flow path 11D, there is a possibility that the flow rate of the hot air may be reduced. If the flow rate of warm air decreases, when the warm air is mixed with the cool air in the gas mixing space 11G, the warm air is blown away by the relatively high-speed cool air, and the two cannot be sufficiently mixed. As a result, it may be difficult to perform accurate temperature adjustment.
However, in the vehicle air conditioner according to the present embodiment, the guide member 40 having the plurality of blades 42 is provided on the downstream side of the warm air flow path 11F. The plurality of blades 42 extend from the warm air flow path toward the gas mixing space. Therefore, the flow of the cool air and the warm air can be disturbed by the blades 42, and a complicated flow can be generated. This can promote mixing of cool air and warm air. Further, since the plurality of blades 42 are provided so as to sandwich the warm air from the width direction D1, the warm air can be suppressed from spreading outward in the width direction D1 as it goes toward the gas mixing space 11G, and the flow velocity of the warm air can be increased. As a result, the penetration force of the warm air flowing through the gas mixture space with respect to the cool air increases, and the warm air is not blown away by the cool air. This enables the warm air and the cool air to be sufficiently mixed.
In addition, according to the above configuration, the guide member 40 is detachably supported by the frame 11 through the base portion 41. Thus, for example, when the frame 11 is formed by injection molding using a resin, a mold can be manufactured regardless of the shape of the guide member 40. Further, since the guide member 40 is configured to be detachable, the shape of the guide member 40 itself can be flexibly changed.
Further, since the plurality of blades 42 are provided so as to be detachable from the base portion 41 integral with the housing 11 as described above, when the plurality of blades 42 are detachably provided to the housing 11, the shape, the installation direction, the installation position, and the like of the plurality of blades 42 can be easily changed in accordance with the flow of warm air.
Also, according to the above-described structure, the plurality of blades 42 extend obliquely in such a manner as to be close to each other. As a result, the space (flow path) between the blades 42 becomes gradually narrower toward the downstream side of the flow of the warm air, and the flow rate of the warm air flowing through the space between the blades 42 can be increased. As a result, mixing of warm air and cool air can be further promoted.
Further, according to the above configuration, by arranging the upper ends of the respective blades 42 at the position of the middle height of the cool air communication port 51 below the gas mixing space 11G, it is possible to minimize the occurrence of disturbance of cool air in the vicinity of the cool air communication port 51 in the upper portion of the cool air communication port 51, and it is possible to ensure proper circulation of cool air in the region. In particular, noise and vibration during the maximum cooling operation (when the opening degree of the cold air communication port 51 is maximized) can be suppressed, and a decrease in the efficiency of the entire apparatus due to an increase in pressure loss can be suppressed. The front end of each vane 42 is disposed at a position spaced rearward from the cool air communication port 51, and therefore does not significantly obstruct the flow of cool air.
The first embodiment of the present invention has been described above. In addition, various changes and modifications may be made to the above-described structure without departing from the spirit of the present invention. For example, in the above embodiment, an example was described in which the number of the blades 42 of the guide member 40 is 4. However, the number of the blades 42 is not limited to 4, and may be changed as appropriate according to the technical requirements or design. For example, as shown in fig. 4, only 2 blades 42 may be provided.
Second embodiment
Next, a second embodiment of the present invention will be described with reference to fig. 5. The same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. As shown in fig. 5, in the present embodiment, the guide member 40 has only 2 blades 42B, and these blades 42B extend in the same direction as each other. Specifically, each of the blades 42B extends obliquely from the other side toward one side in the width direction D1 as it goes from one side toward the other side in the front-rear direction D2. The blades 42B may extend in parallel with each other as long as they extend obliquely in the same direction, and the angles of inclination with respect to the width direction D1 may be different from each other.
According to this structure, the plurality of vanes 42B extend obliquely toward the slide damper 19 in the same direction as each other. This allows the warm air to be smoothly guided to one side in the width direction D1 by the blades 42B. As a result, the cold air and the warm air can be alternately flowed, and the mixing of the warm air and the cold air can be promoted.
The second embodiment of the present invention has been described above. In addition, various changes and modifications may be made to the above-described structure without departing from the spirit of the present invention. For example, in the above embodiment, an example was described in which the number of the blades 42B of the guide member 40 is 2. However, the number of the blades 42B is not limited to 2, and may be changed as appropriate according to the technical requirements or design. In contrast to the above, the blade 42B may extend obliquely from the side in the width direction D1 toward the other side from the side in the front-rear direction D2 toward the other side.
Third embodiment
Next, a third embodiment of the present invention will be described with reference to fig. 6. The same components as those of the above embodiments are denoted by the same reference numerals, and detailed description thereof is omitted. As shown in fig. 6, the guide member 40 has only 2 blades 42C, 42D, and these blades 42C, 42D extend in different directions from each other. The blade 42C located on the other side in the width direction D1 extends from the other side in the width direction D1 toward one side as it goes from one side toward the other side in the front-rear direction D2. On the other hand, the vane 42D located on the side of the width direction D1 extends in the front-rear direction D2.
According to this structure, the plurality of vanes 42C, 42D extend toward the damper in the same direction as each other. This enables smooth warm air guidance. Further, the 2 blades 42C and 42D are arranged so as to gradually approach each other toward the other side in the front-rear direction D2, and therefore the flow rate of the warm air can be increased. As a result, mixing of warm air and cool air can be promoted.
The third embodiment of the present invention has been described above. In addition, various changes and modifications may be made to the above-described structure without departing from the spirit of the present invention. For example, in the above embodiment, an example was described in which the number of the blades 42C, 42D of the guide member 40 is 2. However, the number of the blades 42C and 42D is not limited to 2, and may be changed as appropriate according to the technical requirements or design.
