[0003] [Patent Document 1] JP 2008-18918 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above air conditioning device, since the quarter trim air outlet is provided behind the rear seats, it is difficult to reliably deliver the conditioned air blown out from this air outlet to the feet of the passengers who are located in front of the rear seats. In other words, since the conditioned air is diffused within the passenger compartment after being blown out from the air outlet into the passenger compartment, in order to deliver it to the feet of the passengers in the rear seats, it is necessary to give directionality to the conditioned air and guide it to the feet of the passengers in the rear seats.

[0005] To address this problem, it is effective to extend the duct forward or increase the number of air outlets. However, this solution requires complex and major design changes to the entire duct, which is disadvantageous in terms of increasing the cost and weight of the equipment.

[0006] The present invention has been made in view of the above-mentioned problems, and aims to provide a vehicle air conditioner that can efficiently supply conditioned air into the vehicle compartment using a simple structure. [Means for solving the problem]

[0007] One aspect of the present invention is An air conditioning air supply device mounted on a vehicle, a trim portion having an air outlet provided at a position facing a vehicle interior; an air conditioning air guide portion provided in an opposing space between a seat cushion portion of the vehicle seat and a vehicle body floor portion; Equipped with The air conditioning air guide section has a guide path that guides the air conditioning air in the longitudinal direction of the vehicle, an inlet opening that introduces the air conditioning air blown out from the air outlet of the trim section into the passenger compartment into the guide path, and an outlet opening that discharges the air conditioning air from the guide path into the passenger compartment. death, the vehicle seat is a slide seat that is slidable in the front-rear direction between a front position that is a position farthest from the air outlet of the trim portion to a rear position that is a position closest to the air outlet of the trim portion, the air-conditioning air guide portion has a standing wall provided around the introduction opening in order to guide the air-conditioning air, is fixed integrally to a lower surface of the seat cushion portion of the sliding seat, and is configured to move forward and backward in response to the sliding seat sliding in the forward and backward direction, When the slide seat is disposed at the front position, the conditioned air blown out from the air outlet of the trim portion is supplied to an area behind the slide seat, and when the slide seat is disposed at the rear position, the conditioned air blown out from the air outlet of the trim portion is guided by the conditioned air guide portion and supplied to an area in front of the slide seat. air conditioning air supply equipment, is located. Effect of the Invention

[0008] In the air-conditioning air supply device of the above aspect, the trim part is provided with an outlet port at a position facing the vehicle compartment, and an air-conditioning air guide part having a guide path, an inlet opening, and an outlet opening is provided in an opposing space between a seat cushion part of the vehicle seat and a vehicle body floor part.

[0009] According to the air-conditioning air guide section, the air-conditioning air blown into the vehicle compartment from the air outlet of the trim section is introduced into the taxiway from the inlet opening, guided in the longitudinal direction of the vehicle along the taxiway, and then discharged from the taxiway into the vehicle compartment through the outlet opening. This makes it possible to guide the air-conditioning air from the rear of the vehicle seat to the feet of the occupant of the vehicle seat over a short route.

[0010] In this case, by utilizing the opposing space between the seat cushion portion of the vehicle seat and the vehicle body floor portion and providing an air conditioning air guide portion in this opposing space, there is no need for complex and large-scale design changes such as extending the air conditioning duct or increasing the number of air outlets.

[0011] As described above, according to the above-mentioned aspects, it is possible to provide a vehicle air conditioner that can efficiently supply conditioned air into the vehicle compartment using a simple structure. [Brief description of the drawings]

[Figure 8] FIG. 4 is a plan view for explaining the Coanda effect of the conditioned air blown out from the air outlet of the trim portion. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] In the above-mentioned air-conditioning air supply device, the air-conditioning air guide portion preferably has an upright wall provided upright around the introduction opening for guiding the air-conditioning air.

[0014] According to this air-conditioning air supply device, the standing wall can be used to form an opening space that is effective in inducing the air-conditioning air into the introduction opening. Therefore, it is possible to form an air-conditioning air flow in which the air-conditioning air blown out from the air outlet of the trim part flows along the surface of the standing wall so as to be drawn into the introduction opening. This makes it possible to increase the amount of air-conditioning air guided from the rear of the vehicle seat to the feet of the occupant of the vehicle seat.

[0015] In the above-mentioned air conditioning air supply device, the vehicle seat is a slide seat that is slidable in the front-rear direction between a front position and a rear position, It is preferable that the air conditioning air guide portion is fixed integrally to the underside of the seat cushion portion of the sliding seat, and that when the sliding seat is positioned in either the front position or the rear position, the introduction opening is configured to face the air outlet of the trim portion.

[0016] According to this air-conditioning air supply device, by integrating the air-conditioning air guide portion with the sliding seat, the supply destination of the air-conditioning air blown out from the air outlet in the trim portion can be switched depending on the sliding position of the sliding seat.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific examples of embodiments of an air conditioning air supply device mounted on a vehicle will be described with reference to the drawings.

[0018] In the drawings referred to in the following description, the front of the vehicle is indicated by an arrow FR, the upper side of the vehicle is indicated by an arrow UP, and the inside of the vehicle is indicated by an arrow IN. Furthermore, unless otherwise specified, the front-to-rear direction (vehicle length direction) of the air-conditioning air supply device mounted on the vehicle is indicated by an arrow X, the left-to-right direction (vehicle width direction) is indicated by an arrow Y, and the up-down direction (vehicle height direction) is indicated by an arrow Z.

[0019] (Embodiment 1) As shown in FIG. 1, the vehicle 1 according to the first embodiment is a minivan equipped with a front vehicle seat 10A and two rows of rear vehicle seats 10B and 10C. The vehicle seat 10A is arranged in a first area 2 of the vehicle interior 1a. The vehicle seat 10B is a second-row vehicle seat arranged in a second area 3 behind the first area 2 of the vehicle interior 1a. The vehicle seat 10B is a so-called "captain seat", and the two vehicle seats 10B are arranged adjacent to each other in the left-right direction Y. The vehicle seat 10C is a third-row vehicle seat arranged in a third area 4 behind the second area 3 of the vehicle interior 1a. The vehicle seat 10C is a three-seater seat, and is a so-called "bench seat".

[0020] The arrangement of the vehicle seats in the vehicle 1 is merely illustrative and is not limited to that shown in Fig. 1. For example, the rear seats may be arranged in other than two rows. Also, the structure and shape of each vehicle seat can be appropriately changed from that shown in Fig. 1.

[0021] The vehicle seat 10B has seat leg portions 13 (see FIG. 3) on both sides in the left-right direction Y, and the seat leg portions 13 are supported so as to be slidable in the front-rear direction X via slide rails 14 provided on the vehicle body floor portion 1b so as to extend in the front-rear direction X. That is, the vehicle seat 10B is configured as a slide seat that is slidable in the front-rear direction X between a front position P1 and a rear position P2. Therefore, the position of the legs L of the occupant C changes forward and backward as the vehicle seat 10B slides in the front-rear direction X.

[0022] As shown in FIG. 1, an air-conditioning air supply device 101 of the first embodiment is mounted on a vehicle 1, and includes a trim section 5 and an air-conditioning air guide section 20.

[0023] (Trim structure) The trim part 5 is configured by a right interior part provided in a protruding manner in the third region 4 of the vehicle interior 1a. The trim part 5 is disposed rearward of the vehicle seat 10B and has two air outlets 8, 9. Both of these two air outlets 8, 9 are provided adjacent to each other at a position below the seat cushion part 11 of the vehicle seat 10B and facing the third region 4 of the vehicle interior 1a. In addition, these two air outlets 8, 9 are provided so as to communicate with the air conditioning air flow path 7 formed inside the duct 6. Therefore, the air conditioning air generated by the heater unit (not shown) can be supplied to the vehicle interior 1a from the two air outlets 8, 9 through the air conditioning air flow path 7 of the duct 6. At this time, the air conditioning air blown out from the two air outlets 8, 9 is made into hot air for warming the feet of the occupants.

[0024] As shown in Fig. 2, the first air outlet 8 located at the front of the two air outlets 8, 9 opens diagonally forward with respect to the vehicle interior 1a. In contrast, the second air outlet 9 located at the rear of the two air outlets 8, 9 opens diagonally forward with respect to the vehicle interior 1a, but opens at a slight incline toward the front side than the first air outlet 8. That is, when the trim portion 5 is viewed from above the vehicle interior 1a, the angle θ1 between an imaginary line K extending in the front-rear direction X and the opening direction of the first air outlet 8 is slightly larger than the angle θ2 between the imaginary line K and the opening direction of the second air outlet 9. With this configuration, the conditioned air blown out from each of the two air outlets 8, 9 can interfere with each other at the boundary portion.

[0025] The trim section 5 has a flow restricting section 6a provided in a convex shape between the first air outlet 8 and the second air outlet 9 in the air conditioning air flow path 7. In this case, the second air outlet 9 is disposed upstream of the first air outlet 8 in the direction in which the air conditioning air flows through the air conditioning air flow path 7. The flow restricting section 6a is configured to increase the diversion ratio of the air conditioning air flowing toward the first air outlet 8 compared to the second air outlet 9 by blocking and restricting a part of the flow of the air conditioning air toward the second air outlet 9.

[0026] According to this configuration, the conditioned air blown out from the first air outlet 8 becomes a mainstream air flow with a larger air volume and a faster blowing speed than the conditioned air blown out from the second air outlet 9. Therefore, the first air outlet 8 can also be called a "main air outlet" or a "main air opening." In contrast, the conditioned air blown out from the second air outlet 9 becomes a side flow air flow with a smaller air volume and a slower blowing speed than the conditioned air blown out from the first air outlet 8. Therefore, the second air outlet 9 can also be called a "side flow outlet" or a "side flow opening."

[0027] (Structure of air conditioning air guide section) The conditioned air flow guide portions 20 are provided in opposing spaces 12 between the seat cushion portions 11 of the left and right vehicle seats 10B and the vehicle body floor portion 1b. The upper surfaces of the seat cushion portions 11 form the seating surfaces of the occupants C. The conditioned air flow guide portions 20 are fixed integrally to the lower surfaces of the seat cushion portions 11 of the vehicle seats 10B. Therefore, the conditioned air flow guide portions 20 move forward and backward in response to the sliding of the vehicle seats 10B in the fore-and-aft direction X.

[0028] The air-conditioned air guide section 20 has a taxiway 21, an inlet opening 24, and an outlet opening 27. The taxiway 21 is a guide space for guiding the air-conditioned air in the longitudinal direction X of the vehicle 1. The inlet opening 24 is an opening for introducing a portion of the air-conditioned air blown out from the air outlets 8, 9 of the trim section 5 into the passenger compartment 1a into the taxiway 21. The outlet opening 27 is an opening for guiding the air-conditioned air from the taxiway 21 to the passenger compartment 1a.

[0029] 3, the air-conditioning airflow guide section 20 has a front wall 25 that defines the front side of the taxiway 21, a right wall 28 that defines the right side of the taxiway 21, and a left wall 29 that defines the left side of the taxiway 21. The front wall 25 is provided with a slit section 26 having lattice-shaped slit openings that form the outlet opening 27.

[0030] 4, the air conditioning air guide section 20 further has a rear wall 22 that defines the rear side of the guide path 21. The rear wall 22 is provided with a slit section 23 having a lattice-shaped slit opening that constitutes the introduction opening 24. The slit section 23 is disposed to face the air outlets 8 and 9 of the trim section 5 across a space.

[0031] The upper side of the taxiway 21 is defined by the lower surface of the seat cushion portion 11 of the vehicle seat 10B, and the lower side of the taxiway 21 is defined by the surface of the vehicle body floor portion 1b. As a result, the taxiway 21 is an enclosed space that is enclosed in three directions, the front-rear direction X, the left-right direction Y, and the up-down direction Z, except for the openings of the inlet opening 24 and the outlet opening 27 and a small gap formed between the openings and the surface of the vehicle body floor portion 1b. In this case, the taxiway 21 is formed to have a roughly rectangular prism shape.

[0032] 4 and 5, the conditioned airflow guide section 20 has an upright wall 22a provided upright around the introduction opening 24. A space 22b surrounded by this upright wall 22a is an opening space effective for guiding the conditioned airflow to the introduction opening 24. For this reason, as shown in Fig. 5, an conditioned airflow flow (see the arrow in Fig. 5) is formed in which the conditioned airflow blown out from the first air outlet 8 is guided into the introduction opening 24 along the surface of the upright wall 22a.

[0033] Next, with reference to Figs. 6 and 7, a state in which conditioned air is blown out from the two air outlets 8, 9 of the trim portion 5 into the vehicle interior 1a will be described.

[0034] 6, when the second-row vehicle seat 10B is in the front position P1, the distance in the front-rear direction X of the third area 4 of the vehicle interior 1a becomes maximum. At this time, the vehicle seat 10B is disposed at a position farthest from the two air outlets 8, 9 of the trim part 5 among the respective sliding positions in the front-rear direction X. At this time, the conditioned air blown out from the two air outlets 8, 9 is mainly supplied to the third area 4 of the vehicle interior 1a.

[0035] 7, when the second-row vehicle seat 10B is in the rear position P2, the distance in the front-rear direction X of the third area 4 of the vehicle interior 1a is minimum. At this time, the vehicle seat 10B is disposed in a position closest to the two air outlets 8, 9 of the trim part 5 among the respective sliding positions in the front-rear direction X. Therefore, the conditioned air blown out from the two air outlets 8, 9 is guided by the conditioned air guide part 20 provided below the seat cushion part 11 of the right-side vehicle seat 10B.

[0036] The conditioned air flows forward from the third area 4 of the vehicle interior 1a to the second area 3 through the induction path 21 of the conditioned air induction section 20. As described above, the induction path 21 is partitioned both vertically and horizontally, and allows the flow of the conditioned air only in the front-rear direction X. Therefore, unlike a simple open space where the conditioned air flows, the induction path 21 is effective in guiding the conditioned air with directionality from the third area 4 to the second area 3. At this time, the conditioned air blown out from the two air outlets 8, 9 is supplied to both the second area 3 and the third area 4 of the vehicle interior 1a.

[0037] Referring to Figures 6 and 7, by integrating the air conditioning air guide section 20 with the vehicle seat 10B, which is a sliding seat, the destination of the air conditioning air blown out from the air outlets 8, 9 of the trim section 5 can be switched depending on the sliding position of the vehicle seat 10B.

[0038] By using the air conditioning wind guide section 20, even if the position of the trim section 5 is restricted, the air conditioning wind blown out from the air outlets 8, 9 provided in the trim section 5 can be reliably guided to the second area 3 away from the air outlets 8, 9.

[0039] 8, when the trim portion 5 is disposed, for example, directly beside a vehicle seat 10C, the first air outlet 8 is opened so that the conditioned air blown into the vehicle interior 1a is supplied to a first supply area A1 adjacent to a target obstacle W. Here, the seat leg portion 13 on the right side of the vehicle seat 10C is the obstacle W. In contrast, the second air outlet 9 is opened so that the conditioned air blown into the vehicle interior 1a is supplied to a second supply area A2 located at the boundary between the obstacle W and the first supply area A1.

[0040] The conditioned air blown out from the first air outlet 8 has a high blowing speed and a sufficient air volume can be ensured, so that it can be directly aimed at the feet of the occupant on the right and center of the vehicle seat 10C, which is the target of air conditioning located away from the first air outlet 8 in the first supply area A1. Therefore, the conditioned air blown out from the first air outlet 8 can be delivered to the feet of the occupant in the first supply area A1 without being obstructed by obstacles W.

[0041] On the other hand, when the airflow speed of the conditioned air blown out from the second air outlet 9 is slow and the volume of the air is insufficient, it is difficult to directly target the feet of the occupant on the left side of the vehicle seat 10C, which is the target of air conditioning located away from the second air outlet 9. For this reason, it is difficult to sufficiently deliver the conditioned air blown out from the second air outlet 9 to the feet of the occupant on the left side of the vehicle seat 10C.

[0042] Therefore, the trim section 5 of this embodiment is configured so that the conditioned air blown into the vehicle compartment 1a from the first air outlet 8 of the two air outlets 8, 9 draws in the conditioned air blown into the vehicle compartment 1a from the second air outlet 9 by the Coanda effect, thereby increasing the air volume. In order to obtain this Coanda effect, it is preferable to appropriately set the arrangement and orientation of the two air outlets 8, 9 and the relationship between the relative blowing air speeds of the two air outlets 8, 9.

[0043] The "Coanda effect" referred to here makes use of a known phenomenon related to fluids, and a detailed explanation of this will be omitted; however, it generally refers to a phenomenon in which a fluid draws in or pulls in surrounding fluids as it flows due to the effect of its viscosity.

[0044] In the present embodiment, the Coanda effect refers to a phenomenon in which the conditioned air, which is the main flow with a high flow rate (the conditioned air blown out from the first outlet 8), draws in a secondary flow (the conditioned air blown out from the second outlet 9) with a slower flow rate around it due to the effect of its viscosity. In order to obtain this Coanda effect, it is preferable to use the flow regulating portion 6a (see FIG. 2) to control the blowing speed of the conditioned air blown out from the first outlet 8 to be faster and the blowing speed of the conditioned air blown out from the second outlet 9 to be slower than the first outlet 8.

[0045] According to a structure for obtaining this Coanda effect (hereinafter referred to as the "Coanda structure"), even if the blowing speed of the conditioned air blown out from the second air outlet 9 is slow, the conditioned air blown out from the first air outlet 8 entrains the conditioned air as it flows through the vehicle interior 1a, thereby increasing the volume of the air. At this time, a Coanda flow F is formed at the boundary between the first supply area A1 and the second supply area A2, in which the conditioned air blown out from the first air outlet 8 entrains the conditioned air blown out from the second air outlet 9 (see FIG. 8).

[0046] This allows the conditioned air blown out from the second air outlet 9 to be pulled to the third supply area A3 diagonally forward to the left beyond the obstacle W, making it possible to deliver a sufficient amount of air to the feet of the occupant on the left side of the vehicle seat 10C. That is, the second supply area A2 by the second air outlet 9 can be extended to the third supply area A3 compared to a case where the Coanda effect cannot be obtained. As a result, even if the positions and number of the air outlets 8, 9 are limited, the conditioned air blown out from the first air outlet 8 and the second air outlet 9 work together to deliver the conditioned air to a wide area in the vehicle compartment 1a in a balanced manner.

[0047] The present inventors have confirmed this effect in an actual fluid analysis (CFD analysis) carried out using a computer system.

[0048] Next, the effects of the above-mentioned embodiment 1 will be described.

[0049] In the air-conditioning air supply device 101 of the first embodiment, the trim portion 5 is provided with air outlets 8, 9 at positions facing the vehicle interior 1a. Also, an air-conditioning air guide portion 20 having a guide path 21, an inlet opening 24, and an outlet opening 27 is provided in an opposing space 12 between a seat cushion portion 11 of the vehicle seat 10B and a vehicle body floor portion 1b.

[0050] According to the air-conditioning air guide section 20, the air-conditioning air blown out from the air outlets 8, 9 of the trim section 5 into the vehicle interior 1a can be introduced into the taxiway 21 from the inlet opening 24, guided in the longitudinal direction X of the vehicle 1 on the taxiway 21, and then guided from the taxiway 21 into the vehicle interior 1a through the outlet opening 27. This makes it possible to guide the air-conditioning air from the rear of the vehicle seat 10B to the feet of the occupant C of the vehicle seat 10B over a short route.

[0051] In this case, by utilizing the opposing space 12 between the seat cushion portion 11 of the vehicle seat 10B and the vehicle body floor portion 1b and providing an air conditioning air guide portion 20 in this opposing space 12, there is no need for complicated and large-scale design changes such as extending the air conditioning duct or increasing the number of air outlets.

[0052] As described above, according to the first embodiment, it is possible to provide the conditioned air supply device 101 that can efficiently supply conditioned air into the vehicle interior 1a using a simple structure.

[0053] In addition, by combining a Coanda structure and the air-conditioning air guide section 20, the air-conditioning air supply device 101 is effective in achieving both the function of delivering the air-conditioning air to distant areas within the vehicle interior 1a and the function of guiding the air-conditioning air with directionality to the desired area.

[0054] The present invention is not limited to the above-described embodiment, and various applications and modifications are possible without departing from the object of the present invention.

[0055] In the above-described embodiment, an example was given of a case in which a standing wall 22a is provided around the inlet opening 24 of the air-conditioning air guide section 20. However, for example, if a desired volume of air-conditioning air can be introduced from the inlet opening 24 into the guide path 21, this standing wall 22a may be omitted.

[0056] In the above-described embodiment, an example was given of a case in which the air conditioning air guide section 20 is provided on the vehicle seat 10B, which is a sliding seat. However, instead of this, a structure equivalent to the air conditioning air guide section 20 may be provided on another sliding seat other than the vehicle seat 10B, or on a fixed vehicle seat that is fixed to the vehicle floor section 1b so as not to be able to slide.

[0057] In the above embodiment, the air-conditioning air supply device 101 having both the air-conditioning air guide section 20 and the Coanda structure has been exemplified, but in this air-conditioning air supply device 101, it is also possible to omit only the Coanda structure.

[0058] In the above-described embodiment, an example was given of a case in which the trim portion 5 is positioned rearward of the vehicle seat 10B, and the conditioned air blown out from the air outlets 8, 9 is guided forward by the air conditioned air guide portion 20 when the vehicle seat 10B is in the rear position P2. However, instead, the trim portion 5 may be positioned forward of the vehicle seat 10B, and the conditioned air blown out from the air outlets 8, 9 may be guided rearward by the air conditioned air guide portion 20 when the vehicle seat 10B is in the front position P1.

[0059] In the above embodiment, the trim section 5 is provided with two air outlets 8, 9, but the number of air outlets is not limited to this, and the number of air outlets can be one or three or more as necessary. In addition, the conditioned air blown out from the first air outlet 8 is the main stream and the conditioned air blown out from the second air outlet 9 is the secondary stream. However, instead of this, a structure in which the conditioned air blown out from the second air outlet 9 is the main stream and the conditioned air blown out from the first air outlet 8 is the secondary stream, or a structure in which the blowing speed and air volume of the conditioned air blown out from the two air outlets 8, 9 are approximately the same can be adopted.

[0060] In the above embodiment, a structure in which warm air generated by the heater unit is supplied to the vehicle interior 1a as conditioned air has been illustrated, but it goes without saying that this structure can also be applied to a structure in which cool air is supplied to the vehicle interior 1a as conditioned air.
