[0007] In an air delivery device of an automotive entry device, it may be desirable to increase the range of an airflow so that an air conditioning sensation is provided not only to the area of ​​the front seat but also to the area of ​​the rear seat of a vehicle. However, in the case where the function for adjusting the direction of the airflow is provided in patent document 1, the range of the airflow delivered at the time of adjusting the direction of the airflow tends to be short. Such a problem may occur not only in the entry device for motor vehicles but also in other fluid delivery devices for dispensing a fluid.

[0008] One object of the present invention is to create a fluid dispensing device that is capable of increasing the range of a dispensed fluid even when a direction of fluid flow is set.

[0009] The inventors of the present invention have extensively investigated increasing the range of the fluid in a fluid dispensing device. According to their investigations, when the fluid is dispensed from the device, a lateral vortex flow is generated due to a velocity gradient of the fluid. This vortex flow disperses the main flow, causing it to spread out. An external fluid from the outside of the device is then blown through this lateral vortex flow. In this case, the range of the fluid may be reduced.

[0010] The present invention was made on the basis of the investigations described above. The object of the invention is achieved by a fluid dispensing device with the features of claim 1. An alternative fluid dispensing device is shown in claim 2. Advantageous further developments are the subject of the dependent claims. Accordingly, the auxiliary flow channel is provided in the adjusting rib. Therefore, the fluid dispensing device has a structure in which the auxiliary flow dispensed by the auxiliary flow channel flows parallel to the main flow flowing through the fluid flow channel. Since in this case the development of the lateral (sideways) vortex flow formed in the main flow can be suppressed by the auxiliary flow, a distribution (diffusion) of the main flow and the drawing in of an external fluid, which is drawn into the main flow from the outside of the device, can be suppressed / avoided.Furthermore, if the direction of the fluid blown out of the opening is adjusted by the adjusting rib, the flow direction of the auxiliary flow can be aligned with the flow direction of the fluid flowing through the fluid flow channel. Thus, even when the direction of the fluid discharged from the opening is adjusted, the range of the discharged fluid can be extended.

[0011] In this case, the auxiliary frame body defining the auxiliary flow channel is located on the outer section of the adjustment rib. The fluid delivery device is configured in such a way that the auxiliary flow discharged from the auxiliary flow channel merges with the main flow flowing in the outer area and flows parallel to the main flow within the main flow channel. Since the development of the lateral vortex flow formed in the main flow can be suppressed by the auxiliary flow, diffusion of the main flow and the intake of an external fluid from the outside of the device into the main flow can be avoided. Furthermore, the fluid delivery device is designed such that the direction of the auxiliary flow is changed to match the direction of the main flow when the direction of the fluid blown from the opening is adjusted.Thus, even if the direction of the fluid blown out of the opening is adjusted, the range of the main flow can be extended. Accordingly, the fluid delivery device is able to increase the range of the delivered fluid even when the flow direction of the fluid is adjusted.

[0013] Exemplary embodiments of the present invention are described below with reference to the drawings. In the following exemplary embodiments, sections that are the same as or equivalent to those described in previous exemplary embodiments are designated by the same reference numerals, and a description of the same or equivalent sections may be omitted. Furthermore, if only a part of the components is described in the exemplary embodiment, the components described in the previous exemplary embodiment may be applied to other parts of the components. The respective exemplary embodiments described herein may be partially combined with one another, provided that no special problems arise, even if such combinations are not expressly stated. First embodiment

[0014] The present embodiment is based on the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. 10. In the present embodiment, an example is described in which a fluid delivery device 1 of the present invention is applied to an air delivery device of an air conditioning unit (ACU) that air-conditions a vehicle interior. The air conditioning unit ACU is, for example, arranged inside a dashboard located at the frontmost section of a passenger compartment. The air delivery device of the air conditioning unit ACU is installed on or inside the dashboard.

[0015] The in Fig. The fluid delivery device 1 shown in Figure 1 is a device designed to deliver conditioned air at a temperature set by the air conditioning unit (ACU) into the vehicle interior. The fluid delivery device 1 is designed to have a duct 10 and a grille section 20, which directs the airflow into the vehicle interior. In the drawing, arrows labeled DRud, DRfr, and DRw indicate an upward and downward direction, a forward and backward direction, and a left and right direction, respectively, when the fluid delivery device is mounted on a vehicle.

[0016] As this is shown in the Fig. 1 and Fig. As shown in Figure 2, the shaft (channel) 10 is formed from a substantially rectangular, tube-like element, and an air conditioning flow channel 100 is formed within it. The shaft 10 is provided with an opening 101 at a downstream end of the flow channel 100. A grid section 20 is located in the shaft 10 at a position close to the opening 101 in the flow channel 100, which is formed inside the shaft 10.

[0017] The shaft 10 is connected to the air conditioning unit ACU via an air conditioning shaft D such that the air, whose temperature or humidity has been set, is introduced as a fluid into the flow channel 100 inside the base section 10. In the previous embodiment, the air conditioning unit ACU is an adjusting device that sets the temperature or humidity of the air introduced into the shaft 10. The opening 101 of the shaft 10 has a shallow opening shape in which a vertical dimension of the opening 101 is smaller than a horizontal dimension of it.

[0018] The grid section 20 is housed in the flow channel 100 of shaft 10 and regulates the flow direction of the air blown out of the opening 101 of shaft 10. As this is shown in Fig. As shown in Figure 3, the grid section 20 has a main frame body 21, a plurality of adjusting ribs 22 extending along the upward and downward direction DRud inside the main frame body 21, and a secondary frame body 23.

[0019] The main frame body 21 defines a main flow channel 210, which guides a portion of the airflow flowing through the flow channel 100 into the opening 101 as the main flow. The main frame body 21 is made of an essentially rectangular, tubular element that can be accommodated inside the shaft 10. In other words, the main frame body 21 has an outer shape that can be inserted into the interior of the shaft 10.

[0020] More precisely, the main frame body 21 comprises a left frame 211 and a right frame 212 extending along the upward and downward directions DRud, and an upper frame 213 and a lower frame 214 positioned at opposite ends of the left frame 211 and the right frame 212. The upper frame 213 and the lower frame 214 are connected to both the left frame 211 and the right frame 212. The upper frame 213 and the lower frame 214 have a dimension that is longer than a dimension of the left frame 211 and the right frame 212, such that a right-angled flow channel is formed inside the main frame body 21.

[0021] The left frame 211 and the right frame 212 extend along a longitudinal direction (that is, in this example, the upward and downward direction DRud) of the adjusting rib 22. In the present embodiment, the left frame 211 and the right frame 212 form a pair of vertical frames that extend along the longitudinal direction of the adjusting rib 22.

[0022] The upper frame 212 and the lower frame 214 are arranged longitudinally at two end faces of the adjusting rib 22 and extend along one thickness direction of the adjusting rib 22 (in this embodiment, in the left and right directions DRw). In the present embodiment, the upper frame 213 and the lower frame 214 form a pair of horizontal frames that are connected at both ends in the longitudinal direction of the adjusting rib 22 to both the left frame 211 and the right frame 212.

[0023] As this is shown in the Fig. 4 and Fig. As shown in Figure 5, the upper frame 213 and the lower frame 214 have wall sections 213a, 214a which face the ends of the adjusting ribs 22 in the longitudinal direction of the adjusting ribs 22, and the wall sections 213a, 214a are provided with fitting grooves (insertion grooves) 213b, 214b into which pivot pins 222 of the adjusting ribs 22 described below are inserted.

[0024] The numerous adjustment ribs 22 are designed as a flow direction adjustment element for adjusting the direction of the airflow blown out of the opening 101. For example, five adjustment ribs 22 are arranged in the grille section 20. The number of adjustment ribs 22 arranged in the grille section 20 is not limited to five and can be less than five, equal to six, or more than six. That is, at least one adjustment rib 22 can be arranged in the grille section 20.

[0025] The multiple adjustment ribs 22 are rotatably arranged in the flow channel 100. The multiple adjustment ribs 22 of the present embodiment have longitudinal ends that are rotatably supported on the upper frame 213 and the lower frame 214 of the main frame body 21 in such a way that the direction of the airflow can be adjusted in the left and right directions DRw.

[0026] In the present embodiment, the section of the adjusting rib 22 that is closer to the upper frame 213 than a central section in the longitudinal direction of the adjusting rib 22 is designed as a first outer section 220a, and the section of the adjusting rib 22 that is closer to the lower frame 214 than the central section in the longitudinal direction of the adjusting rib 22 is designed as a second outer section 220b. Furthermore, in the present embodiment, the section of the adjusting rib 22 that is closer to the central section in the longitudinal direction than the main frame body 21 is designated as an inner section 220c, as shown in Fig. 5 is shown.

[0027] As this is in Fig. As shown in Figure 6, the adjusting rib 22 has a plate section 221 extending along the upward and downward direction DRud, and pivot pins 222 provided at two ends in the longitudinal direction of the plate section 221. The pivot pin 222 is sized to fit into the insertion slots 213b and 214b of the main frame body 21.

[0028] The pivot pins 222 are each inserted into the insertion grooves 213b, 214b of the main frame body 21 such that the adjusting rib 22 can be rotated about the pivot pin 222, as shown in Fig. Figure 7 is shown. Although not shown, the pivot pins 222 of the plurality of adjusting ribs 22 are connected by a connecting element so that they can be rotated together (in conjunction with each other). An actuator (not shown) is connected to the connecting element so that the plurality of adjusting ribs 22 are driven by this actuator.

[0029] The secondary frame body 23 defines an auxiliary flow channel 230, which directs the remaining airflow, with the exception of the airflow flowing through the main flow channel 210, to the opening 101 as an auxiliary flow from the airflow flowing through the flow channel 100.

[0030] As this is shown in the Fig. 5 and Fig. As shown in Figure 6, the subframe body 23 is integrally formed with the adjusting rib 22 such that the direction of the auxiliary flow blown out of the auxiliary flow channel 230 is aligned with the direction of the main flow blown out of the main flow channel 210. That is, the subframe body 23 is designed such that the direction of the auxiliary flow (side flow) blown out of the auxiliary flow channel 230 changes synchronously with the direction of the main flow blown out of the main flow channel 210.

[0031] The subframe body 23 is designed in a tubular form. The auxiliary flow channel 230 is formed by an inner wall section 231 of the subframe body 23. The subframe body 23 of the present embodiment is designed such that the cross-sectional area of ​​the auxiliary flow channel 230 is essentially constant.

[0032] The secondary frame body 23 is positioned on the adjusting rib 22 such that a portion of the main flow channel 210 and the auxiliary flow channel 230 overlap in the circumferential direction of the main frame body 21. That is, the adjusting ribs 22 that are adjacent to each other are arranged with respect to the main frame body 21 such that a portion of the main flow channel 210 is formed between the secondary frame bodies 23. The secondary frame bodies 23 are each positioned with respect to the first outer section 220a and the second outer section 220b of the adjusting rib 22 such that they are aligned in an outer area of ​​the main flow channel 210 near the main frame body 21 in the circumferential direction of the main frame body 21. More precisely, the secondary frame bodies 23 are positioned at both ends in the longitudinal direction of the plate section 221 that forms the adjusting rib 22.As a result, the auxiliary flow channel 230 is positioned between the adjusting ribs 22 and the inner wall surface of the channel 10. The auxiliary flow then flows essentially parallel to the main flow flowing along the inner wall surface of the shaft 10.

[0033] The operation of the fluid dispensing device 1 is described below with reference to the Fig. 8, Fig. 9 to Fig. 10 described. When the air conditioning unit (ACU) is operating, conditioned air at a temperature or humidity set by the ACU flows into the fluid delivery device 1 through an air conditioning duct. The conditioned air flowing into the fluid delivery device 1 passes through the flow channel 100 of the duct 10, and then a portion of the conditioned air flows into the main flow channel 210 and the remainder flows into the auxiliary flow channel 230. As described in Fig. As shown in Figure 8, the conditioned air flowing through the main flow channel 210 and the auxiliary flow channel 230 is blown into the vehicle interior.

[0034] Fig. Figure 9 shows a diagram illustrating a state of the airflow blown out of a fluid dispensing device CE of a comparative example, in comparison to the first embodiment. The fluid dispensing device CE, as the comparative example, differs from the fluid dispensing device 1 of the present embodiment in that the auxiliary flow channel 230 is not provided in the grid section 20. To facilitate understanding of the description, the following are shown in Figure 9: Fig. In the fluid dispensing device CE of the comparative example shown in Figure 9, the same reference numerals have been applied as in the fluid dispensing device 1 of the first embodiment for the elements that have the same functions as in the fluid dispensing device 1 of the present embodiment.

[0035] As this is in Fig. As shown in Figure 9, in the fluid delivery device CE of the comparative example, when the main flow is blown out of the main flow channel 210, countless lateral vortex flows Vt are generated due to the velocity difference between the main airflow from the main flow channel 210 and the still air surrounding the main airflow at the downstream side of the outlet of the main flow channel 210. The main airflow is dispersed (diffusion) by the lateral vortex flow Vt, and simultaneously, the still air on the outside of the device (i.e., the external fluid) is drawn into the main airflow, thus shortening the reach of the main airflow and the fluid delivery device CE. In this case, the lateral vortex flows Vt combine with each other, and the lateral vortex flows Vt can develop into a larger lateral vortex flow Vt.Furthermore, when still air, which is stationary on the outside of the device, is drawn into the main airflow, the temperature or humidity of the main airflow changes. Therefore, it can be difficult for conditioned air, set to a suitable temperature or humidity, to reach a desired space. Lateral vortex flow is a vortex flow in which the vortex axis, as the central axis of the vortex flow, is essentially perpendicular to the main flow direction.

[0036] In contrast, in the fluid delivery device 1 of the present embodiment, as shown in Fig. Figure 10 shows that the auxiliary flow blown out of the auxiliary flow channel 230 is parallel to the main flow blown out of the main flow channel 210, and it flows together with the main flow into the outer area of ​​the main flow channel 210.

[0037] Accordingly, the lateral vortex flow Vt formed in the main flow is disturbed by the auxiliary flow, and the development of the lateral vortex flow Vt can be suppressed or prevented. This suppresses or prevents the distribution (diffusion) of the main flow and the drawing in of still air (i.e., external fluid) from the outside of the device into the main flow. As a result, the reach of the main flow can be increased. Furthermore, when the development of the lateral vortex flow Vt is suppressed or prevented, it becomes more difficult for still air on the outside of the device to be drawn into the main flow. Therefore, the conditioned air, adjusted to a suitable temperature or humidity, easily reaches the desired space.

[0038] Furthermore, in the fluid delivery device 1 of the present embodiment, the auxiliary flow channel 230 is designed by the secondary frame body 23, which is provided on the adjusting rib 22, such that the direction of the main flow blown out of the main flow channel 210 changes synchronously with the direction of the auxiliary flow blown out of the auxiliary flow channel 230.

[0039] The fluid delivery device 1 described above has a design in which the auxiliary flow delivered by the auxiliary flow channel 230 flows together with and parallel to the main flow delivered from the outer surface within the main flow channel 210. Since the development of the lateral vortex flow Vt formed in the main flow can be suppressed or prevented by the auxiliary flow, it is possible to prevent or suppress the diffusion of the main flow and the intake of the external fluid from the outside of the device into the main flow. As a result, the range of the main flow can be increased.

[0040] Furthermore, the fluid delivery device 1 is designed to change the direction of the auxiliary flow so that it matches the direction of the main flow when the direction of the airflow blown out of the opening 101 is adjusted. Accordingly, even when the direction of the air blown out of the opening 101 is adjusted, the auxiliary flow can suppress / avoid the development of the lateral vortex flow Vt generated around the main flow. As a result, the range of the main flow can be increased.

[0041] In particular, the fluid delivery device 1 is provided with the auxiliary frame bodies 23, which form the auxiliary flow channel 230 at the two end sides of the adjusting ribs 22 in the longitudinal direction of the adjusting ribs 22. Accordingly, the development of the lateral vortex flow Vt, which is formed in the main flow near the two end sides of the adjusting rib 22, can be suppressed / avoided.

[0042] The secondary frame body 23 is positioned on the adjusting rib 22 such that a portion of the main flow channel 210 and the auxiliary flow channel 230 overlap each other in the circumferential direction of the main frame body 21. Accordingly, the auxiliary flow emitted from the auxiliary flow channel 230 flows readily together with and parallel to the main flow flowing in the outer area of ​​the main flow channel 210, beneath the main flow emitted from the main flow channel 210. Therefore, the development of lateral vortex flow generated near the outer area of ​​the main flow can be further avoided / suppressed.

[0043] Furthermore, the auxiliary frame body 23 is provided at the end of the plate section 221 of the adjusting rib 22 in the longitudinal direction. As a result, the auxiliary flow discharged from the auxiliary flow channel 230 can easily flow parallel to and adjacent to the main flow, which flows in the outer area within the main flow channel 210. Thus, the development of the lateral vortex flow Vt, which forms in the main flow near the two end faces of the adjusting rib 22, can be effectively avoided.

[0044] Furthermore, the subframe body 23 is formed in a tubular shape, and the auxiliary flow channel 230 is defined by the inner wall section 231 of the subframe body 23. In this way, since the auxiliary flow channel 230 is formed by the inner wall section 231 of the tubular subframe body 23, the auxiliary flow channel 230 can be easily added to the fluid delivery device 1, which has the main flow channel 210. Second embodiment

[0045] Below is a second embodiment with reference to the Fig. 11 and Fig. 12 described. In the present embodiment, the flow channel shape of an auxiliary flow channel 230 differs from that of the first embodiment. In the present embodiment, the difference compared to the first embodiment is mainly described, and the description of the part that is similar to that in the first embodiment has been omitted.

[0046] In a flow channel 100 inside a shaft 10, the flow velocity of the airflow near the wall surface tends to be lower than at a position further away from the wall surface due to the loss of wall area. Therefore, if the auxiliary frame bodies 23 are simply provided closer to the wall surface defining the flow channel 100 in the outer sections 220a and 220b of the adjusting ribs 22, the flow rate of the fluid flowing through the auxiliary flow channel 230 may be insufficient.

[0047] In the second embodiment, as shown in the Fig. 11 and Fig. As shown in Figure 12, the auxiliary frame body 23 is constructed such that the cross-sectional area of ​​the auxiliary flow channel 230 on an upstream side of the airflow is larger than on a downstream side of the airflow of the auxiliary flow channel 230.

[0048] More precisely, in the auxiliary frame body 23, a vertical dimension L1 of an opening at an upstream end of the auxiliary flow is larger than a vertical dimension L2 of an opening at a downstream end of the auxiliary flow. In other words, the size of the auxiliary frame body 23 in the longitudinal direction of the plate section 221 of the adjusting rib 22 is larger on the upstream side than on the downstream side of the auxiliary flow.

[0049] The remaining structure is the same as in the first embodiment. The other parts of the fluid dispensing device 1 according to the present embodiment have configurations similar to those in the first embodiment. Therefore, the action and effect produced by the structure of the first embodiment can be achieved here in the same way as in the first embodiment. The same applies to the following embodiments.

[0050] In particular, in the fluid delivery device 1 of the present embodiment, the cross-sectional area of ​​the auxiliary flow channel 230 is larger on the upstream side than on the downstream side in the auxiliary flow direction. Accordingly, the air flows easily from the flow channel 100 to the auxiliary flow channel 230. Therefore, it is possible to ensure a sufficient flow rate of the air flowing through the auxiliary flow channel 230. As a result, the development of the lateral vortex flow Vt, which forms in the main flow, can be sufficiently prevented by the auxiliary flow. Variation in the second embodiment

[0051] In the second embodiment described above, the cross-sectional area of ​​the auxiliary flow channel 230 changes between the upstream and downstream sides of the auxiliary flow by changing the dimension of the secondary frame body 23 in the longitudinal direction of the plate section 221 of the secondary frame body 23. However, the present invention is not limited to this.

[0052] For example, a dimension of the auxiliary frame body 23 can be changed in a direction perpendicular to the longitudinal direction of the plate section 221 between the upstream and downstream sides of the auxiliary flow such that the cross-sectional area of ​​the auxiliary flow channel 230 changes. If the auxiliary frame bodies 23, which are provided adjacent to each other on the adjusting ribs 22, are too close to each other, the auxiliary flow discharged from the adjacent auxiliary flow channels 230 may interfere with each other. Therefore, it is desirable to establish a predetermined distance between the adjacent adjusting ribs 22 such that the auxiliary frame bodies 23 provided on the adjacent adjusting ribs 22 do not come too close to each other. Third example

[0053] Below is a third embodiment with reference to the Fig. 13 and Fig. 14. The present embodiment differs from the first embodiment in that a grid section 20 is designed such that the direction of the airflow can be adjusted not only in the left and right directions DRw but also in the upward and downward directions DRud. The present embodiment mainly describes the part that differs from the first embodiment, and the description of the part that is similar to the first embodiment is omitted.

[0054] In the grid section 20, the main frame body 21 is rotatably supported with respect to the shaft 10. That is, in the main frame body 21, the left frame 211 and the right frame 212, which extend along the longitudinal direction of the adjusting rib 22, are rotatably supported with respect to the shaft 10.

[0055] More precisely, the left frame 211 and the right frame 212 are provided with pivot pins 211a and 212a, which project towards the shaft 10. The shaft 10 is provided with fitting sections (insertion sections) 111, 121, into which the pivot pins 211a, 212a of the main frame body 21 are each inserted (fitted) into the pair on side walls 11, 12, which face the left frame 211 and the right frame 212.

[0056] The main frame body 21 is rotatable about the pivot pins 211a and 212a, as shown in Fig. Figure 14 shows that the pivot pins 211a and 212a of the main frame body 21 are rotatably inserted into the insertion sections 111 and 121 of the shaft 10.

[0057] The remaining structure is the same as in the first embodiment. In the fluid delivery device 1 of the present embodiment, the main frame body 21 of the grid section 20 is rotatably supported with respect to the shaft 10. Accordingly, the direction of the airflow can be adjusted by rotating the main frame body 21 with respect to the shaft 10, in addition to adjusting the direction of the airflow by rotating the adjusting ribs 22. Therefore, the degree of freedom in adjusting the direction of the airflow blown out of the opening 101 can be improved. Fourth embodiment

[0058] Below is a fourth embodiment with reference to the Fig. 15 and Fig. 16. In the present embodiment, the position at which the subframe body 23 is provided differs from that in the first embodiment. In the present embodiment, mainly the part that differs from the first embodiment is described, and the description of the part similar to the first embodiment is omitted.

[0059] As this is shown in the Fig. 15 and Fig. As shown in Figure 16, the secondary frame body 23 is designed in a tubular shape and is provided on both sides of the plate surface of the plate section 221. More precisely, the secondary frame body 23 is provided on both sides of the plate surface of the plate section 221, which forms the first outer section 220a and the second outer section 220b of the adjusting rib 22.

[0060] The remaining structure of the present embodiment is the same as in the first embodiment. In the fluid delivery device of the present embodiment, the auxiliary frame body 23 is positioned on both sides of the plate surface of the plate section 221 of the adjusting rib 22. Accordingly, the auxiliary flow delivered by the auxiliary flow channel 230 flows easily together with and parallel to the main flow, which flows in the outer area of ​​the main flow channel 210, and beneath the main flow delivered by the main flow channel 210. Therefore, the development of the lateral vortex flow Vt, which forms near the outer area of ​​the main flow, can be suppressed even more effectively. Variation in the fourth embodiment

[0061] The fourth embodiment described above illustrates an example in which the auxiliary frame bodies 23 are each arranged in contact with both sides of the plate surface of the plate section 221; however, the present invention is not limited to this. If the auxiliary frame bodies 23, which are arranged adjacent to each other on the adjusting ribs 22, are too close to each other, the auxiliary flow emitted by the adjacent auxiliary flow channels 230 can interfere with each other. Therefore, for example, the auxiliary frame body 23 and the plate section 221 can be connected via a connecting element such that the auxiliary frame body 23 is separated (spaced apart) from the plate surface of the plate section 221. Fifth embodiment

[0062] Below is a fifth embodiment with reference to the Fig. 17 and Fig. 18 described. In the present embodiment, the shape of the subframe body 23 differs from that of the first embodiment. In the present embodiment, mainly the parts that differ from the first embodiment are described, and the description of those parts that are similar to those in the first embodiment is omitted.

[0063] As this is shown in the Fig. 17 and Fig. As shown in Figure 18, the secondary frame body 23 has a shape that covers facing wall sections 213a and 214a, which comprise a section of the main frame body 21 and are oriented towards the end of the adjusting rib 22 in the longitudinal direction of the adjusting rib 22. The auxiliary flow channel 230 is formed by an inner wall section 231 of the secondary frame body 23 and the facing wall sections 213a and 214a of the main frame body 21. More precisely, the secondary frame body 23 is provided with an L-shaped part on both sides of the plate surface of the plate section 221.

[0064] The remaining structure is the same as in the first embodiment. The auxiliary flow channel 230 is formed by the inner wall section 231 of the secondary frame body 23 and the adjacent wall sections 213a and 214a of the main frame body 21. Accordingly, the auxiliary flow discharged from the auxiliary flow channel 230 flows easily together with and parallel to the main flow flowing in the outer area of ​​the main flow channel 210, beneath (from) the main flow discharged from the main flow channel 210. Therefore, the development of the lateral vortex flow Vt, which forms near the outer area in the main flow, can be even better avoided / suppressed. Variation in the fifth embodiment

[0065] The fifth embodiment described above illustrates an example in which the secondary frame body 23 is arranged on both sides of the plate surface of the plate section 221; however, the present invention is not limited thereto. The secondary frame body 23 can be provided at one end of the plate section 221 or on one side of the plate surface of the plate section 221. Furthermore, the secondary frame body 23 is not limited to an L-shape and can, for example, have a shape that extends linearly or can have a shape that is curved in an arc. Sixth embodiment

[0066] Below is a sixth embodiment with reference to the Fig. 19, Fig. 20, Fig. 21 to Fig. 22 described. The present embodiment differs from the first embodiment in that a grid section 20 is constructed such that it has lateral ribs 24 and vertical ribs 26. In the present embodiment, mainly the part that differs from the first embodiment is described, and the description of the part that is similar to the first embodiment has been omitted.

[0067] As this is shown in the Fig. 19 and Fig. As shown in Figure 20, the grid section 20 is constructed such that it has a plurality of lateral ribs 24 extending along the left and right direction DRw inside the shaft 10, a plurality of vertical ribs 26 extending along the upward and downward direction DRud, and a plurality of secondary frame bodies 25. In the present embodiment, the lateral ribs 24 and the vertical ribs 26 are constructed such that they form adjusting ribs that adjust the direction of the airflow blown out of the opening 101.

[0068] The lateral ribs 24 change the direction of the airflow blown out of the opening 101, directing it upwards and downwards. The lateral ribs 24 are positioned close to the opening 101 on the inside of the shaft 10.

[0069] The grid section 20 of the present embodiment has, for example, three lateral ribs 24. The three lateral ribs 24 are rotatably supported with respect to the left wall section 102 and the right wall section 103 of the shaft 10. The number of lateral ribs 24 arranged in the grid section 20 is not limited to three and can be less than three, equal to four, or more than four. That is to say, at least one lateral rib 24 can be arranged in the grid section 20.

[0070] The three lateral ribs 24 are a first lateral rib 241, which faces an upper wall section 104 of the shaft 10, a second lateral rib 242, which faces a lower wall section 105 of the shaft 10, and a third lateral rib 243, which is arranged between the first lateral rib 241 and the second lateral rib 242. In each of the lateral ribs 241, 242, 243, the ends of the lateral ribs 241, 242, 243 are rotatably supported in the longitudinal direction (that is, in this example in the left and right directions DRw) on the left wall section 102 and the right wall section 103 of the shaft 10.

[0071] The lateral ribs 241, 242, 243 are each provided with flat plate sections 241a, 242a, 243a, extending horizontally along the left and right directions DRw, and with pivot pins located at the longitudinal ends of the flat plate sections 241a, 242a, 243a. Although not shown, the pivot pins 241b, 242b, 243b are sized to allow insertion into grooves formed in the left wall section 102 and the right wall section 103 of the shaft 10. Furthermore, the lateral ribs 241, 242, 243 are connected by a connecting element such that their positions can be changed while they are operationally connected to one another. An actuator (not shown) is connected to the connecting element, and the plurality of lateral ribs 241, 242, 243 are driven by an actuator.The vertical rib 26 changes the direction of the airflow blown out of the opening 101 to the left and right. The vertical ribs 26 are positioned on the inside of the shaft 10 on an upstream side of the lateral ribs 24 such that they do not interfere with the lateral ribs 24.

[0072] At least one vertical rib 26 is arranged in the grid section 20 of the present embodiment. The ends of the vertical rib 26 in the longitudinal direction (that is, in this example in the upward and downward direction DRud) are rotatably supported with respect to the upper wall section 104 and the lower wall section 105 of the shaft 10.

[0073] The vertical rib 26 comprises a plate section 261 extending along the upward and downward direction DRud, and two pivot pins 262 provided at both ends in the longitudinal direction of the plate section 261. Although not shown, the pivot pins 262 are sized to allow insertion into grooves formed in the upper wall section 104 and the lower wall section 105 of the shaft 10. An actuator (not shown) is connected to the vertical rib 26. The vertical rib 26 is driven by this actuator.

[0074] In this section 20, the lateral ribs 24 and the vertical ribs 26 can each be rotated separately. This makes it possible to freely adjust the direction of the airflow blown out of the opening 101.

[0075] The subframe body 25 defines an auxiliary flow channel 250, which directs a portion of the air flowing through the flow channel 100 into the opening 101 as the auxiliary flow. The subframe body 25 is designed in a tubular shape. The auxiliary flow channel 250 is formed by an inner wall section of the subframe body 25. The subframe body 25 of the present embodiment is constructed such that the cross-sectional area of ​​the auxiliary flow channel 250 is essentially constant.

[0076] The auxiliary frame body 25 is positioned relative to the lateral ribs 24 such that the direction of the auxiliary flow blown out of the auxiliary flow channel 250 is aligned with the direction of the main flow blown out of the flow channel 100. In the present embodiment, a plurality of auxiliary frame bodies 25 are provided on the upper surface of the first lateral rib 241 and the lower surface of the second lateral rib 242. Since the auxiliary frame bodies 25 are provided on the upper surface of the first lateral rib 241 and the lower surface of the second lateral rib 242, the auxiliary flow channels 250 are formed between the inner wall surface of the shaft 10 and the first lateral rib 241, and between the inner wall surface of the shaft 10 and the second lateral rib 242.

[0077] More precisely, a plurality of subframe bodies 25 are arranged side by side on the first lateral rib 241 in the left and right directions DRw at regular intervals with respect to the upper surface of the first lateral rib 241. The plurality of subframe bodies 25 are provided on the upper surface of the first lateral rib 241 and extend along the forward and rearward directions DRfr.

[0078] More precisely, a plurality of subframe bodies 25 are arranged side by side on the second lateral rib 242 in the left and right directions DRw at regular intervals with respect to the lower surface of the second lateral rib 242. The plurality of subframe bodies 25 are provided on the lower surface of the second lateral rib 242 and extend along the forward and rearward directions DRfr. The third lateral rib 243 is not provided with a subframe body 25.

[0079] The distance between adjacent subframe bodies 25 is greater than the width of each subframe body 25 in the left and right directions DRw. As a result, the auxiliary flow channels 250 formed inside the subframe body 25 have a sufficiently smaller cross-sectional area than the flow channel through which the main flow formed between the adjacent subframe bodies 25 passes.

[0080] When the air conditioning unit (ACU) is operating, the conditioned air, whose temperature or humidity is set by the ACU, flows into the fluid delivery device 1 through an air conditioning duct. The conditioned air flowing into the fluid delivery device 1 passes through the flow channel 100 of the duct 10, and a portion of it flows into the auxiliary flow channel 250. The conditioned air flowing through the flow channel 100 and the auxiliary flow channel 250 is then blown into the vehicle interior.

[0081] As this is shown in the Fig. 21 and Fig. As shown in Figure 22, the auxiliary flow blown out of the auxiliary flow channel 250 flows together with and parallel to the main flow of air flowing through the flow channel between the first lateral rib 241 and the upper wall section 104, and the main flow of air flowing through the flow channel between the second lateral rib 242 and the lower wall section 105.

[0082] Accordingly, the lateral vortex flow that forms around the main flow is disrupted by the auxiliary flow, and its development is suppressed / prevented. This prevents the diffusion (distribution / spread) of the main flow and the drawing in of still air (i.e., the external fluid) from outside the device into the main flow. As a result, the range of the main flow can be increased. Furthermore, suppressing the development of the lateral vortex flow makes it more difficult for the still air located outside the device to be drawn into the main flow. Therefore, the conditioned air, which has been adjusted to a suitable temperature or humidity, easily reaches the desired space.

[0083] The fluid delivery device 1 described above has a design in which the auxiliary flow delivered from the auxiliary flow channel 250 flows together with and parallel to the main flow delivered from the outside of the flow channel 100. Since the development of the lateral vortex flow formed in the main flow can be suppressed by the auxiliary flow, diffusion / spreading / distribution of the main flow and the intake of external fluid drawn in from the outside of the device into the main flow can be avoided. As a result, the range of the main flow can be increased.

[0084] Furthermore, in the fluid discharge device 1, the auxiliary flow channel 250 is provided at least between the lateral rib 24 and the inner wall surface of the shaft 10. Thus, the auxiliary flow flows essentially parallel to the main flow, which flows along the inner wall surface of the shaft 10. Therefore, the development of the lateral vortex flow that forms in the main flow can be reduced by the auxiliary flow.

[0085] The opening 101 of shaft 10 has a shallow opening shape, in which the vertical dimension of the opening 101 is less than its horizontal dimension. When the vertical ribs 26 are arranged in such a horizontally long opening 101, the vertical ribs 26 are noticeable.

[0086] On the other hand, in the fluid delivery device 1, the vertical ribs 26 are positioned on the upstream side of the lateral rib 24 inside the shaft 10 such that they are difficult to see from the outside. Accordingly, the adjustment rib's influence on the design of the grille section 20 can be avoided. Furthermore, when the adjustment rib is formed by the lateral rib 24 and the vertical rib 26, it does not protrude from the opening 101 when adjusting the direction of the airflow outwards. Therefore, its influence on the design (the external appearance) of the grille section 20 can be avoided. First modification in the sixth embodiment

[0087] In the sixth embodiment described above, the subframe body 25 provided on the first lateral rib 241 has a tubular shape; however, the present invention is not limited to this. For example, as shown in Fig. As shown in Figure 23, the auxiliary frame body 25 is constructed such that it has a set of side plate sections 251 and 252, which are positioned vertically on the plate surface of the first lateral rib 241. In this case, the auxiliary flow channel 250 is formed by a space enclosed by the plate surface of the first lateral rib 241, a set of side plate sections 251 and 252, and the inner wall of the shaft 10. At this point, the lengths of the plurality of auxiliary frame bodies 25 need not be constant along the airflow direction. Although not shown, the auxiliary frame body 25 provided at the second lateral rib 242 can also have a set of side plate sections 251 and 252. Second variation in the sixth embodiment

[0088] Furthermore, the secondary frame body 25 provided on the first lateral rib 241 can have a different shape on the upstream and downstream sides of the airflow. As shown in Fig. As shown in Figure 24, the auxiliary frame body 25 can be designed from a set of side plate sections 251 and 252 on the upstream side of the airflow and a tubular body 253 on the downstream side of the airflow. Accordingly, the cross-sectional area on the upstream side of the airflow in the auxiliary flow channel 250 is large, and the air flows easily from the flow channel 100 into the auxiliary flow channel 230. Therefore, it is possible to adequately control the flow rate of the air flowing through the auxiliary flow channel 250. As a result, the development of the lateral vortex flow that forms in the main flow can be sufficiently suppressed by the auxiliary flow. Although not shown, the subframe body 25 provided on the second lateral rib 242 may also include a set of side plate sections 251 and 252 and the tubular body 253. Further variations in the sixth embodiment

[0089] The subframe body 25 is not limited to a square cylinder and can be designed, for example, as a round cylinder or a triangular cylinder. The distance between adjacent subframe bodies 25 does not necessarily have to be constant. The multitude of subframe bodies 25 can comprise various shapes and sizes.

[0090] In the sixth embodiment described above, the first lateral rib 241 and the second lateral rib 242 are provided with auxiliary frame bodies 25; however, the present invention is not limited thereto. The auxiliary frame bodies 25 can be provided on either the first lateral rib 241 or the second lateral rib 242. The same applies to the following embodiments. Seventh embodiment

[0091] Below is a seventh embodiment with reference to the Fig. 25 and Fig. 26 described. In the present embodiment, the positions of the lateral ribs 24 and the vertical ribs 26 differ from those in the sixth embodiment. In the present embodiment, mainly those parts that differ from the sixth embodiment are described, and the parts that are similar to the sixth embodiment are not described. As described in the Fig. 25 and Fig. As shown in Figure 26, in the grid section 20 of the present embodiment, the positions of the lateral ribs 24 and the positions of the vertical ribs 26 in the forward and rearward directions DRfr are reversed compared to the sixth embodiment. The vertical ribs 26 are arranged in positions close to the opening 101 on the inside of the shaft 10. The lateral ribs 24 are arranged in a position on the inside of the shaft 10 on an upstream side of the vertical rib 26.

[0092] The remaining structure is the same as in the sixth embodiment. The fluid delivery device 1 of the present embodiment has a structure in which the auxiliary flow delivered from the auxiliary flow channel 250 flows together with and parallel to the main flow delivered from the outer area of ​​the flow channel 100. For this reason, the fluid delivery device 1 of the present embodiment can achieve the same advantages as in the sixth embodiment. Eighth embodiment

[0093] Below is an eighth embodiment with reference to the Fig. 27 and Fig. 28. The present embodiment differs from the sixth embodiment in that the subframe bodies 25 are provided on both sides of the lateral rib 24. In the present embodiment, mainly those parts that differ from the sixth embodiment are described, and the part that is similar to that in the sixth embodiment is not described.

[0094] As this is shown in the Fig. 27 and Fig. As shown in Figure 28, a multitude of auxiliary frame bodies 25 are provided on both sides of the first lateral rib 241. Since the auxiliary frame bodies 25 are provided on both sides of the first lateral rib 241, the auxiliary flow channels 250 can be formed not only between the inner wall surface of the shaft 10 and the first lateral rib 241, but also between the first lateral rib 241 and the third lateral rib 243.

[0095] A multitude of auxiliary frame bodies 25 are provided on both sides of the lateral rib 242. Since the auxiliary frame bodies 25 are provided on both sides of the second lateral rib 242, the auxiliary flow channels 250 can be formed not only between the inner wall surface of the channel 10 and the second lateral rib 242, but also between the second lateral rib 242 and the third lateral rib 243.

[0096] More precisely, on the first lateral rib 241 and the second lateral rib 242, numerous secondary frame bodies 25 are arranged side by side in the left and right directions DRw at regular intervals with respect to the two surfaces of each of the first lateral rib 241 and the second lateral rib 242. Furthermore, the first lateral ribs 241 and the second lateral ribs 242 are arranged such that the secondary frame body 25 located on the upper surface and the secondary frame body 25 located on the lower surface are aligned in the upward and downward directions DRud.

[0097] Furthermore, the subframe body 25 is constructed in the same manner as in the first modification of the sixth embodiment. The subframe body 25 can be formed from a different shape (for example, from a tubular frame) that differs from the first modification of the sixth embodiment.

[0098] The remaining structure is the same as in the sixth embodiment. The fluid delivery device 1 of the present embodiment has a structure in which the auxiliary flow delivered from the auxiliary flow channel 250 flows together with and parallel to the main flow delivered from the outer area of ​​the flow channel 100. For this reason, the fluid delivery device 1 of the present embodiment can achieve the same advantages as in the sixth embodiment.

[0099] In particular, when the auxiliary flow channels 250 are provided on both sides of the first lateral rib 241 and the second lateral rib 242 as in the present embodiment, the auxiliary airflow flows easily parallel to the main flow, even when the direction of the airflow is adjusted. As a result, the development of the lateral vortex flow that forms in the main flow can be satisfactorily and sufficiently suppressed (avoided) by the auxiliary flow. Variation in the eighth embodiment

[0100] In the eighth embodiment described above, the secondary frame bodies 25, which are provided on both sides of the first lateral rib 241 and the second lateral rib 242, are arranged such that they are aligned in the upward and downward direction DRud; however, the present invention is not limited to this. For example, as shown in Fig. As shown in Figure 29, the first lateral rib 241 is designed such that the secondary frame bodies 25 provided on the upper surface and the secondary frame bodies 25 provided on the lower surface are not arranged in the upward and downward direction DRud. Furthermore, the first lateral rib 241 can be provided with a plurality of secondary frame bodies 25 arranged side by side in the left and right direction DRw at different intervals. The same applies to the second lateral rib (this can also be applied to it). Ninth embodiment

[0101] Below is a ninth embodiment with reference to Fig. 30. The present embodiment differs from the sixth embodiment in that the auxiliary flow channels 245 are provided on at least one surface of the lateral rib 24. In the present embodiment, mainly the part that differs from the sixth embodiment is described, and the description of the part that is similar to the sixth embodiment is omitted.

[0102] As this is in Fig. As shown in Figure 30, a plurality of groove sections 244, extending along the forward and backward directions DRfr, are formed with respect to the upper surface of the first lateral rib 241. More precisely, a plurality of concave groove sections 244 are arranged side by side at regular intervals on the upper surface of the first lateral rib 241 in the left and right directions DRw. The plurality of groove sections 244 define an auxiliary flow channel 245, which directs a portion of the air flowing through the flow channel 100 to the opening 101, as the auxiliary flow. That is, the auxiliary flow channel 245 is formed between the inner wall surface of the shaft 10 and the first lateral rib 241 by the plurality of groove sections 244 formed on the upper surface of the first lateral rib 241.The multiple groove sections 244 of the present embodiment comprise groove sections of different lengths in the forward and rearward directions DRfr. The multiple groove sections 244 can have the same length in both the forward and rearward directions DRfr.

[0103] Although not shown, a plurality of groove sections 244 extending in the forward and backward directions DRfr can be formed with respect to the lower surface of the second lateral rib 242. More precisely, a plurality of concave groove sections 244 are arranged side by side in the left and right directions DRw at regular intervals on the lower surface of the second lateral rib 242. That is, the auxiliary flow channel 245 is formed between the inner wall surface of the shaft 10 and the second lateral rib 242 by the plurality of groove sections 244 formed on the lower surface of the second lateral rib 242.

[0104] The remaining structure is the same as in the sixth embodiment. The fluid delivery device 1 of the present embodiment has a structure in which the auxiliary flow delivered from the auxiliary flow channel 250 flows together with and parallel to the main flow delivered from the outer area of ​​the flow channel 100. For this reason, the fluid delivery device 1 of the present embodiment can achieve the same advantages as in the sixth embodiment.

[0105] In particular, if the auxiliary flow channel 245 is designed from a plurality of groove sections 244 formed on a surface of the first lateral rib 241 and the second lateral rib 242 as in the present embodiment, the thickness of the entire rib can be reduced compared to a design in which the auxiliary frame bodies 25 are provided in each of the lateral ribs 241 and 242. In this case, it is not necessary to add a dedicated element for forming the auxiliary flow channel 245. Therefore, the grid section 20 can be simplified. Variation in the ninth embodiment

[0106] In the ninth embodiment described above, a plurality of groove sections 244 are formed on the upper surface of the first lateral rib 241 and the lower surface of the second lateral rib 242; however, the present invention is not limited thereto. As shown in Fig. As shown in Figure 31, a plurality of groove sections 244 can be formed on both faces (both surfaces) of the first lateral rib 241. It is desirable that the plurality of groove sections 244 on both sides of the first lateral rib 241 be formed at different positions such that they are offset in the left- and right-pointing directions DRw. This can limit the decrease in strength at the first lateral rib 241.

[0107] Furthermore, the first lateral rib 241 can be provided with a plurality of groove sections 244, arranged side by side in the left and right directions DRw at different intervals. Moreover, the shape of the plurality of groove sections 244 is not limited to a rectangular shape and can, for example, be an arc shape, a triangular shape, or the like. The same can be applied to the second lateral rib 242. Tenth embodiment

[0108] Below is a tenth embodiment with reference to the Fig. 32 and Fig. 33. The present embodiment differs from the sixth embodiment in that auxiliary flow channels 247 are provided in the lateral rib 24. In the present embodiment, mainly the part that differs from the sixth embodiment is described, and the part that is similar to the sixth embodiment is not described.

[0109] As this is shown in the Fig. 32 and Fig. As shown in Figure 33, the first lateral rib 241 is provided with a plurality of through-holes 246 extending along the surface of the plate. More precisely, the first lateral rib 241 has a plurality of through-holes 246 arranged side by side at regular intervals in the left and right directions DRw. The plurality of through-holes 246 defines an auxiliary flow channel 247, which directs a portion of the air flowing through the flow channel 100 to the opening 101 as the auxiliary flow. That is, the auxiliary flow channel 247 is formed between the inner wall surface of the shaft 10 and the first lateral rib 241 by the plurality of through-holes 246 formed in the first lateral rib 241.The cross-section of the plurality of through holes 246 of the present embodiment is not limited to a round shape, but can be a square shape or a triangular shape.

[0110] Furthermore, although not shown, the second lateral rib 242 is also formed with a plurality of through holes 246 extending along the plate surface. More precisely, the second lateral rib 242 has a plurality of through holes 246 arranged side by side at regular intervals in the left and right directions. That is to say, the auxiliary flow channel 247 is formed between the inner wall surface of the shaft 10 and the second lateral rib 242 by the plurality of through holes 246 formed in the second lateral rib 242.

[0111] The remaining setup is the same as in the sixth embodiment. The fluid delivery device 1 of the present embodiment has a design in which the auxiliary flow delivered from the auxiliary flow channel 250 flows together with and parallel to the main flow delivered from the outer surface of the flow channel 100. Therefore, the effect and the result described in the sixth embodiment can be achieved here in the same way as in the sixth embodiment.

[0112] If the auxiliary flow channel 247 is formed from a plurality of through holes 246, which are formed in the first lateral rib 241 and the second lateral rib 242 as in the present embodiment, the auxiliary flow can be provided even more stably compared to the case in which the auxiliary flow channel 247 is formed by the groove section 244. In this case, it is not necessary to add an element for forming the auxiliary flow channel 247. Therefore, the grid section 20 can be simplified. Variation in the tenth embodiment

[0113] In the tenth embodiment described above, a plurality of through holes 246 are provided in the plate section 241a of the first lateral rib 241 and the plate section 242a of the second lateral rib 242; however, the present invention is not limited thereto. For example, as shown in Fig. As shown in Figure 34, a transverse wall section 241c is provided at the end of the plate section 241a of the first lateral rib 241 on one side of the opening 101, and a plurality of through-holes 246 can be provided in the transverse wall section 241c. In this case, the auxiliary flow channel 247 is formed by the plurality of through-holes 246. The same can be applied to the second lateral rib 242. The transverse wall section 241c extends in a direction that intersects the plate surface of the plate section 241a at the end of the plate section 241a on the side of the opening 101.

[0114] Furthermore, the first lateral rib 241 can be provided with a plurality of through holes 246, arranged side by side in the left and right directions DRw at various intervals. Moreover, the shape of the plurality of through holes 246 is not limited to a circular shape and can, for example, be triangular, square, oblong, or the like. The same can be applied to the second lateral rib 242. Eleventh embodiment

[0115] Below is an eleventh embodiment with reference to Fig. 35. The present embodiment differs from the sixth embodiment, in which auxiliary flow channels 250 are provided in the vertical rib 26. In the present embodiment, mainly the part that differs from the sixth embodiment is described, and the part that is similar to the sixth embodiment is not described.

[0116] The secondary frame body 25 is not attached to a lateral rib 24, but to a vertical rib 26. That is, as shown in Fig. As shown in Figure 35, the auxiliary frame body 25 is positioned relative to the vertical rib 26 such that the direction of the auxiliary flow blown out of the auxiliary flow channel 250 is aligned with the direction of the main flow blown out of the flow channel 100. The auxiliary frame body 25 is tubular in shape, and the auxiliary flow channel 250 is formed by the inner wall surface of the auxiliary frame body 25. More precisely, the auxiliary frame bodies 25 are provided at two end faces in the longitudinal direction of the plate section 261 that forms the vertical rib 26. When the air conditioning unit ACU is operating, the conditioned air, the temperature or humidity of which is set by the air conditioning unit ACU, flows into the fluid delivery device 1 through an air conditioning duct.The conditioned air flowing into the fluid delivery device 1 flows through the flow channel 100 of the shaft 10, and a portion of it flows into the auxiliary flow channel 250. The conditioned air flowing through the flow channel 100 and the auxiliary flow channel 250 is then blown into the vehicle interior. At this point, the auxiliary flow discharged from the auxiliary flow channel 250 flows parallel to the main flow, thus suppressing / preventing the development of lateral vortex flow around the main flow.

[0117] The fluid delivery device 1 described above has a design in which the auxiliary flow delivered by the auxiliary flow channel 250 flows together with and parallel to the main flow delivered from the outer surface of the flow channel 100. Due to this design, the development of lateral vortex flow in the main flow can be reduced by the auxiliary flow. Thus, it is possible to prevent diffusion of the main flow and to prevent the intake of external fluid (which is drawn into the main flow from the outside of the device). As a result, the range of the main flow can be increased. Variation in the eleventh embodiment

[0118] In the eleventh embodiment described above, the vertical rib 26 is arranged at a position on the upstream side of the lateral rib 24 inside the shaft 10, but the present invention is not limited thereto. For example, in the grid section 20, as shown in Fig.As shown in Figure 36, the vertical rib 26 is arranged in a position close to the opening 101 inside the shaft 10. In this case, the lateral ribs 24 are arranged in a position on the inside of the shaft 10 on an upstream side of the vertical rib 26. As a result, the auxiliary flow discharged from the auxiliary flow channel 250 can easily flow parallel to and adjacent to the main flow flowing in the outside of the flow channel 100. Therefore, the action and effect described in the eleventh embodiment can be achieved here in the same way as in the eleventh embodiment.

[0119] The eleventh embodiment described above illustrates an example in which the subframe body 25 is formed in a tubular shape; however, the present invention is not limited to this. The subframe body 25 can be formed in a shape other than a tubular shape. Furthermore, the auxiliary flow channel 250 can be formed by a groove or a through-hole provided in the vertical rib 26. Further examples of implementation

[0120] Representative embodiments of the present invention are described above. However, the present invention is not limited to the embodiments presented above and can be modified in various ways as follows.

[0121] In the first to fifth embodiments described above, a structure is illustrated in which the subframe body 23 is provided for both the first outer section 220a and the second outer section 220b of the adjusting rib 22; however, the present invention is not limited thereto. The subframe body 23 can be provided on the first outer section 220a of one adjusting rib 22 and can be provided on the second outer section 220b of the other adjusting rib 22, for example, at the adjusting ribs 22.

[0122] In the first to fifth embodiments described above, the secondary frame body 23 is positioned on the adjusting rib 22 such that a portion of the main flow channel 210 and the auxiliary flow channel 230 overlap each other in the circumferential direction of the main frame body 21. However, the present invention is not limited to this. The secondary frame body 23 can be positioned on the adjusting rib 22 such that it faces the inner wall surface of the main frame body 21 in such a way that the auxiliary flow channel 230 is formed on the outer side of the main flow channel 210.

[0123] In the first to fifth embodiments described above, the main frame body 21, the upper frame 213, and the lower frame 214 have dimensions that are longer than those of the left frame 211 and the right frame 212. However, the present invention is not limited to this. The main frame body 21 can be constructed such that the dimensions of the upper frame 213 and the lower frame 214 are equal to or shorter than those of the left frame 211 and the right frame 212. Furthermore, the main frame body 21 is not limited to a substantially rectangular tube element but can be made from a substantially cylindrical tube element, as long as it can be accommodated inside the shaft 10.

[0124] In the first to fifth embodiments described above, the end sections of the adjusting ribs 22 are rotatably supported longitudinally in the upper frame 213 and the lower frame 214 of the main frame body 21, so that the direction of the airflow can be adjusted in the left and right directions DRw. However, the present invention is not limited to this. The adjusting rib 22 can, for example, be rotatably supported with respect to the left frame 211 and the right frame 212 of the main frame body such that the direction of the airflow can be adjusted in the upward and downward directions DRud. In this case, the direction of the discharged airflow can be adjusted in the upward and downward directions DRud by rotatably supporting the left frame 211 and the right frame 212 of the main frame body 21 with respect to the shaft 10.

[0125] Furthermore, in the first embodiment described above, the numerous adjusting ribs 22 are rotatably supported with respect to the main frame body 21; however, the present invention is not limited thereto. The numerous adjusting ribs 22 can, for example, be rotatably supported with respect to a support shaft that crosses the interior of the main frame body 21 in the left and right directions DRw.

[0126] In the embodiment described above, the air conditioning unit ACU is illustrated as an air conditioning device for adjusting the temperature or humidity of the air introduced into the shaft 10; however, the present invention is not limited thereto. The air conditioning device can, for example, consist of a humidifier that humidifies all or part of the vehicle interior, or a dehumidifier that dehumidifies all or part of the vehicle interior.

[0127] The embodiment described above illustrates an example in which the fluid dispensing device 1 of the present invention is used with an air dispensing device of an air conditioning unit to perform air conditioning (air conditioning) of a vehicle compartment. The invention is not limited thereto. The fluid dispensing device 1 of the present invention can be applied to an air outlet device other than the air dispensing device of the air conditioning unit (ACU). For example, the fluid dispensing device 1 of the present invention is also applicable to a device that blows a gas or a liquid other than air.

[0128] In the exemplary embodiments described above, it is not necessary to state that the elements forming the exemplary embodiments are not necessarily essential, with the exception that those elements are clearly marked as particularly essential in the case where these elements are considered to be obviously essential in principle, and the like.

[0129] In the embodiments described above, the present invention is not limited to the specific number of components of the embodiments, except where such numerical values, such as the number, numerical sizes, quantities, ranges and the like, are expressly explained as indispensable, and where the specific number is obviously required in principle as a limitation, and the like.

[0130] When, in the exemplary embodiments described above, reference is made to the shape, position relationship, and the like of a component, this shall not be considered a restriction to the shape, position relationship, and the like, except where this is specifically stated, in the case where, in principle, a restriction to a specific shape, position relationship, and the like seems necessary, and the like. overview

[0131] A fluid dispensing device shown in some or all of the embodiments described above has a shaft defining a fluid flow channel and providing an opening at a downstream end of the fluid flow channel. It also has a grid section arranged in the fluid flow channel to adjust the flow direction of the fluid dispensed from the opening. The grid section has at least one adjusting rib rotatably mounted in the fluid flow channel and is provided with an auxiliary flow channel that directs a portion of the fluid flowing through the fluid flow channel to the opening as an auxiliary flow. The auxiliary flow channel is configured with the adjusting rib to adjust the flow direction of the auxiliary flow dispensed from the auxiliary flow channel so that it aligns with the flow direction of the fluid flowing through the fluid flow channel.

[0132] According to a second aspect, the auxiliary flow channel is provided at least between the adjustment rib and an inner wall surface of the shaft. Thus, the auxiliary flow flows essentially parallel to a main flow that flows along the inner wall surface of the shaft. Therefore, the development of lateral vortices in the main flow can be reduced by the auxiliary flow. For example, if a main frame body defining a main flow channel is located inside the shaft, the auxiliary fluid flow runs parallel to the main fluid flow that flows along the inner wall surface of the main frame body.

[0133] According to a third aspect, the grid section has a tubular main frame body that defines a main flow channel, which directs a portion of the fluid flowing through the channel to the opening as a main flow, and at least one secondary frame body that defines an auxiliary flow channel. The adjusting rib is located inside the main frame body and is rotatably supported relative to the main frame body. The secondary frame body is positioned at an outer position of the adjusting rib such that the flow direction of the auxiliary flow emitted by the auxiliary flow channel is aligned with the flow direction of the main flow emitted by the main flow channel.

[0134] According to a fourth aspect, the auxiliary frame body of the fluid delivery device is provided on a first outer section, positioned at one end of a longitudinal direction of the adjustment rib, and on a second outer section, positioned at the other end of the longitudinal direction of the adjustment rib. In this case, the auxiliary frame bodies, which define the auxiliary flow channel, are provided at both ends of the adjustment rib along its longitudinal direction. Thus, the development of lateral vortex flow in the main flow near the two ends of the adjustment rib can be effectively suppressed.

[0135] In a fluid delivery device according to a fifth aspect, the auxiliary frame body is designed at the adjusting rib such that a portion of the main flow channel and the auxiliary flow channel overlap each other in a circumferential direction of the main frame body. Accordingly, the auxiliary flow delivered by the auxiliary flow channel flows readily together with and parallel to the main flow flowing in the outer area of ​​the main flow channel, and thus under the main flow delivered by the main flow channel. Therefore, the development of a pronounced lateral vortex flow near the outer area of ​​the main flow can be even more effectively avoided.

[0136] According to a sixth aspect, the auxiliary frame body of the fluid delivery device is constructed such that the cross-sectional area of ​​the auxiliary flow channel on an upstream side is larger than on a downstream side in the auxiliary flow channel.

[0137] In the fluid flow channel inside the shaft, the fluid flow velocity near the wall surface tends to be lower than at a position further away from the wall surface due to the loss of surface area. If the auxiliary frame bodies are simply placed in the outer sections of the setting rib closer to the wall surface defining the fluid flow channel, the flow rate of the fluid flowing through the auxiliary flow channel may be insufficient.

[0138] Conversely, if the cross-sectional area of ​​the auxiliary flow channel is larger on the upstream side than on the downstream side, the fluid can easily flow from the fluid flow channel to the auxiliary flow channel. Therefore, it is possible to ensure a sufficient flow rate of the fluid flowing through the auxiliary flow channel.

[0139] According to a seventh aspect of the fluid delivery device, the main frame body comprises a pair of vertical frames extending along the longitudinal direction of the adjustment rib, and a pair of lateral frames arranged at both ends of the adjustment rib along its longitudinal direction and connected to the pair of vertical frames. The vertical frames, arranged as a pair, are rotatably supported within the main frame body with respect to the shaft.

[0140] According to an eighth aspect of the fluid delivery device, the grid section has at least one auxiliary frame body that defines the auxiliary flow channel. The auxiliary frame body is positioned relative to the adjusting rib such that the flow direction of the auxiliary fluid delivered from the auxiliary flow channel aligns with the flow direction of the main flow delivered from the fluid flow channel. Accordingly, since the auxiliary flow channel is formed by the auxiliary frame body provided in the adjusting rib, the main flow and the auxiliary flow of the fluid flowing in the fluid flow channel can run parallel to each other.

[0141] Accordingly, the fluid flow direction can be adjusted by rotating the main frame body relative to the shaft, in addition to adjusting the fluid flow direction by rotating the adjustment rib. Therefore, the degree of freedom in adjusting the direction of the fluid blown out of the opening can be improved.

[0142] According to a ninth aspect, the adjusting rib of the fluid delivery device has a plate section extending along its longitudinal direction. Furthermore, the auxiliary frame body is provided at one end of the plate section of the adjusting rib in the longitudinal direction. Accordingly, the auxiliary flow discharged from the auxiliary flow channel flows easily together with and parallel to the main flow flowing in the outer area of ​​the main flow channel. Thus, the development of lateral vortex flow, which forms in the main flow near the outer edges of the adjusting rib, can be effectively suppressed.

[0143] According to a tenth aspect, the adjusting rib of the fluid delivery device has a plate section extending along its longitudinal direction. Furthermore, the auxiliary frame body is provided on two surfaces of the plate section of the adjusting rib. Accordingly, the auxiliary flow delivered by the auxiliary flow channel flows easily together with and parallel to the main flow flowing in the outer area of ​​the main flow channel. Therefore, the development of lateral vortex flow, which forms near the outer area of ​​the main flow, can be even better avoided / suppressed.

[0144] According to an eleventh aspect, the auxiliary frame body of the fluid delivery device is designed in a tubular form. The auxiliary flow channel is formed by an inner wall section of the auxiliary frame body. In this way, since the auxiliary flow channel is formed by the inner wall section of the auxiliary frame body, it can be easily added to the fluid delivery device, which has the main flow channel.

[0145] According to a twelfth aspect of the fluid delivery device, the auxiliary frame body has a shape that covers facing wall sections which encompass a section of the main frame body and which face the end of the adjusting rib in the longitudinal direction of the adjusting rib. In this case, the auxiliary flow channel is formed by an inner wall section of the auxiliary frame body and the facing wall section. Since the auxiliary flow channel is formed by the inner wall section of the auxiliary frame body and the facing wall section of the main frame body, the auxiliary flow channel can be easily added to the fluid delivery device, which includes the main flow channel.

[0146] According to a thirteenth aspect, the auxiliary flow channel is formed by at least one groove provided on the surface of the adjusting rib. In this case, it is not necessary to add an element for forming the auxiliary flow channel. Therefore, the grid section can be simplified.

[0147] According to a fourteenth aspect, the auxiliary flow channel is formed by a through-hole provided in the adjustment rib. In this case, it is not necessary to add an element for forming the auxiliary flow channel. Therefore, the grid section can be simplified.

[0148] According to a fifteenth aspect, the shaft of the fluid delivery device is connected to an air conditioning device which is designed to set a temperature or humidity of the air on an upstream side of the airflow, so that conditioned air, as the fluid whose temperature or humidity is set, flows into the fluid flow channel.

[0149] As described above, in the fluid delivery device of the present embodiment, the suction effect of an external fluid drawn into the main flow from the outside of the device can be reduced by the auxiliary flow. Therefore, if the fluid delivery device of the present invention is used as an air delivery device of an air conditioning unit, it can limit the possibility that the temperature or humidity of the conditioned air, which is set by the air conditioning unit, is altered by outside air from the outside of the device, the temperature or humidity of which is not set.In other words, according to the fluid delivery device of the present invention, it becomes easier for the air, whose temperature or humidity has been set by the air conditioning device, to reach a desired room while maintaining the set temperature or humidity.
