Description

[0001] The present disclosure relates to an air conditioning unit according to the preamble of claim 1 for a vehicle. State of the art

[0002] JP 2006 - 510 548 A discloses an air conditioning unit of the air mixing type. The air conditioning unit mixes cool air generated in a cooler and warm air generated in a heater to provide temperature-controlled air (air-conditioned air) and supplies the temperature-controlled air (air-conditioned air) to a vehicle cabin.

[0003] An air conditioning unit is designed so that the space where cool and warm air mix is ​​reduced. This means that warm and cool air are blown from a single air outlet into a vehicle cabin without any mixing. As a result, the temperature of the air blown from the outlet varies considerably. Furthermore, if the mixing space is small and the air is blown from multiple outlets with the same target temperature, the temperature difference between the air blown from these different outlets will be significant. In other words, the temperature variation (fluctuation) of the air blown from different outlets is substantial.

[0004] It is necessary for the air conditioning unit to reduce the noise of the air being blown into the cabin from the air outlet.

[0005] DE 10 2008 021 015 A1 shows an air conditioning unit according to the preamble of claim 1.

[0006] Further state-of-the-art air conditioning units are shown in DE 10 2004 003 196 A1 and DE 10 2006 009 577 A1. Summary of the invention

[0007] The object of the present invention is to improve an air conditioning unit according to the preamble of claim 1 in order to reduce temperature fluctuations of the air blown from one air outlet and temperature fluctuations of the air blown from different air outlets.

[0008] The object of the present invention is achieved by an air conditioning unit having the features of claim 1.

[0009] Advantageous embodiments of the present invention are defined in the dependent claims.

[0010] It is an advantage of the present invention to provide an air conditioning unit that reduces the noise of the air being blown out.

[0011] According to the invention, the airflow passing through the opening is more turbulent compared to the air conditioning unit without the adjustment component. Thus, when the warm air generated in the heater and the cool air generated in the cooler flow into the opening, the warm air and the cool air are mixed by the adjustment component. This reduces the temperature fluctuation of the air blown from the air outlet.

[0012] By positioning the adjustment component to cover the opening, the resistance to the airflow can be adjusted. If the air conditioning unit has multiple openings, at least one opening is covered by the adjustment component. This regulates the mixing ratio of warm and cold air blown from the various air outlets. The mixing ratio is regulated in such a way as to reduce the temperature variation between the air blown from different outlets.

[0013] According to the invention, the partition directs the airflow passing through the opening. This results in a more uniform velocity distribution of the air blown from the air outlet into the cabin. Furthermore, the partition creates resistance to the airflow passing through the opening. This reduces the amount of air blown from the air outlet to the cabin and thus lowers the air velocity.

[0014] As a result, the noise of the expelled air can be reduced compared to the case without the adjustment component.

Description of the exemplary implementations

[0016] The following are exemplary embodiments described with reference to the drawings. Identical or equivalent sections in the respective exemplary embodiments below are designated with the same reference numerals in the drawings. First embodiment

[0017] A schematic structure of an air conditioning unit 10 in a first embodiment of the present disclosure is shown in Fig. 1 and Fig. Figure 2 shows the air conditioning unit 10, which is an air conditioning unit for a vehicle and forms part of an air conditioning system. The air conditioning unit 10 is located in front of a front seat in the vehicle's cabin. In particular, the air conditioning unit 10 is located within an instrument panel. The air conditioning unit 10 supplies air, which has passed through a heat exchanger, to the cabin.

[0018] The air conditioning unit 10 comprises an air conditioning housing 12, a blower (not shown), an evaporator 14, a heater core 16 and a PTC heater (a PTC heating device) 18.

[0019] The air conditioning housing 12 forms an outer frame of the air conditioning unit 10. As in Fig. As shown in Figure 1, the air conditioning housing 12 has several openings 20, 22, and 24. Openings 20, 22, and 24 are openings through which air flows from an inside to an outside of the air conditioning housing 12. Openings 20, 22, and 24 include a face opening 20, a defrost opening 22, and a foot opening 24. The face opening 20 is connected to a face air outlet in the instrument panel (not shown) via a duct (not shown). The defrost opening 22 is connected to a defrost air outlet in the instrument panel (not shown) via a duct (not shown).

[0020] The face air vents feature a central driver air outlet, a side driver air outlet, a central passenger air outlet, and a side passenger air outlet. The central driver air outlet and the side driver air outlet are located on the driver's seat side of the instrument panel. The central passenger air outlet and the side passenger air outlet are located on the passenger seat side of the instrument panel. The central driver air outlet and the central passenger air outlet are located on a central portion of the instrument panel in one side direction of the vehicle. The side driver air outlet and the side passenger air outlet are located on outer portions of the instrument panel in the side direction of the vehicle.

[0021] As in Fig. 1 and Fig. As shown in Figure 3, the face opening 20 has a central driver opening 201, a side driver opening 202, a central passenger opening 203 and a side passenger opening 204. Fig. Figure 3 shows the air conditioning unit 10 without an adjustment component 40, which is described below.

[0022] Although not shown in the figures, the central driver opening 201 is connected to the central driver air outlet. The side driver opening 202 is connected to the side driver air outlet. The central passenger opening 203 is connected to the central passenger air outlet. The side passenger opening 204 is connected to the side passenger air outlet.

[0023] The blower is located in the air conditioning housing 12. The blower creates the air currents that flow through the respective openings 20, 22 and 24.

[0024] The evaporator 14 is located in the air conditioning housing 12. The evaporator 14 is a cooler for cooling the air flowing through each of the openings 20, 22, and 24. The evaporator 14 is a heat exchanger for cooling. The evaporator 14 evaporates a refrigerant, exchanges heat between the air and the refrigerant in a refrigerant circuit, and cools the air.

[0025] The heater core 16 and the PTC heater 18 are arranged in the air conditioning housing 12. The heater core 16 and the PTC heater 18 are heaters (heating devices) that heat (warm) the air flowing through each of the openings 20, 22, and 24. The heater core 16 is a heat exchanger for heating (warming) air through heat exchange between the air and an internal combustion engine cooling water. The PTC heater 18 is an auxiliary heater for heating (warming) the air that has passed through the heater core 16.

[0026] As in Fig. As shown in Figure 2, the air conditioning housing 12 has an air passage 26 through which air flows to each of the openings 20, 22, and 24. The air passage 26 has an upper passage 28, which is located on an upper side of the air conditioning housing 12, and a lower passage 30, which is located on a lower side of the air conditioning housing 12. The upper passage 28 and the lower passage 30 are separated (divided) by a partition 32, which is located in the air conditioning housing 12.

[0027] The upper passage 28 includes an upper part of the evaporator 14 and an upper part of the heater core 16. The upper passage 28 has an upper warm air passage 281, an upper cooling air passage 282, and an upper mixing passage 283, which are arranged in a downstream side of the evaporator 14.

[0028] The upper warm air passage 281 carries warm air, generated by passing through the upper part of the heater core 16, to the upper mixing passage 283. The upper cooling air passage 282 carries cool air, generated by passing through the upper part of the evaporator 14, bypassing the upper part of the heater core 16 and flowing to the upper mixing passage 283. The upper mixing passage 283 carries the mixture of warm air from the upper warm air passage 281 and cool air from the upper cooling air passage 282 to the face opening 20 and the defrost opening 22.

[0029] The lower passage 30 comprises a lower part of the evaporator 14, a lower part of the heater core 16, and the PTC heater 18. The lower passage 30 includes a lower warm air passage 301, a lower cooling air passage 302, and a lower mixing passage 303, which are located on the downstream side of the evaporator 14.

[0030] The lower warm air passage 301 directs the warm air, generated by passing through the lower part of the heater core 16, to the lower mixing passage 303. The lower warm air passage 301 incorporates the PTC heater 18. The air that has passed through the lower part of the heater core 16 is heated by the PTC heater 18. The lower cooling air passage 302 directs the cool air, generated by passing through the lower part of the evaporator 14, bypassing the lower part of the heater core 16 and flowing to the lower mixing passage 303. The lower mixing passage 303 directs the mixture of warm air from the upper warm air passage 301 and cool air from the lower cooling air passage 302 to the foot opening 24, which is located in Fig. As shown in Figure 1, the air passes through a connecting passage 304. The lower mixing passage 303 carries a mixture of warm air from the lower warm air passage 301 and cool air from the lower cooling air passage 302 to the upper mixing passage 283 through a connecting opening 305. The connecting opening 305 is formed on the partition wall 32. The connecting opening 305 is connected to the upper mixing passage 283 and the lower mixing passage 303.

[0031] As in Fig. As shown in Figure 2, the air conditioning unit 10 has an air mixing flap 34 and a blow mode flap 36.

[0032] The air mixing flap 34 is a temperature control flap for regulating (controlling) the temperature of the conditioned air by regulating (controlling) the mixing ratio of the cool air and the warm air. The air mixing flap 34 has an upper air mixing flap 341 and a lower air mixing flap 342. The upper air mixing flap 341 is located between the evaporator 14 and the heater core 16 in the upper passage 28. The lower air mixing flap 342 is located between the evaporator 14 and the heater core 16 in the lower passage 30.

[0033] The blow mode flap 36 selectively opens and closes the openings 20, 22, and 24. The blow mode flap 36 selectively opens and closes the openings 20, 22, and 24 such that a blow mode, such as a face mode and a foot mode, is achieved. The blow mode flap 36 has a face flap 361, a defrosting flap 362, and a foot flap 363. In this embodiment, the foot flap 363 is integrally formed with a flap 364, which opens and closes the connecting opening 305.

[0034] In face mode, the connecting flap 361 opens the face opening 20. The defrosting flap 362 closes the defrosting opening 22. The foot flap 363 closes the connecting passage 304, which is connected to the foot opening 24, and opens the connecting opening 305. The air mixing flap 34 is positioned such that the temperature of the air from the face air outlet is at the desired temperature.

[0035] The warm air from the upper warm air passage 281 and the lower warm air passage 301 and the cool air from the upper cooling air passage 282 and the lower cooling air passage 302 flow towards the face opening 20, while being mixed in the upper mixing passage 283, as indicated by arrows in Fig. 2 is indicated. The air passing through the central driver opening 201, the side driver opening 202, the central passenger opening 203 and the side passenger opening 204 is blown into the cabin accordingly by the central driver air outlet, the side driver air outlet, the central passenger air outlet and the side passenger air outlet.

[0036] Two adjustment components 40, which are in Fig. The items shown in 1 are described below. As shown in Fig. As shown in Figure 1, the air conditioning unit 10 has two adjustment components 40. These two adjustment components 40 comprise a first adjustment component 40a and a second adjustment component 40b. The first adjustment component 40a is arranged to cover the central driver opening 201, and the second adjustment component 40b is arranged to cover the central passenger opening 203. The first adjustment component 40a adjusts the airflow from the central driver opening 201. The second adjustment component 40b adjusts the airflow from the central passenger opening 203. The first adjustment component 40a is integrally formed with the second adjustment component 40b. The first adjustment component 40a is fixed to cover the central driver opening 201. The second adjustment component 40b is fixed to cover the central occupant opening 203.The first adjustment component 40a can be fixed at one end of the channel connected to the central driver opening 201. The second adjustment component 40b can be fixed at one end of the channel connected to the central passenger opening 203.

[0037] As in Fig. As shown in Figure 4, each of the two adjustment components 40 has a frame 42 and a grid 44. The frame 42 is arranged along one end of the openings that are covered by the adjustment component 40.

[0038] The grid 44 is arranged in a region enclosed by the frame 42. The grid 44 has several linear components 46 arranged to form several gaps 45. The linear components 46 form a mesh that defines the gaps 45. In a grid region 47 where the grid 44 is arranged, air can pass through (flow through) the gaps 45. Thus, the gaps 45 are several air passages through which air can pass. The linear components 46 form a partition to define the air passages. In this embodiment, the entire region enclosed by the frame 42 is the grid region 47.

[0039] In particular, as shown in Fig. As shown in Figure 5, the line components 46 consist of several first line components 461 and several second line components 462. The first line components 461 are arranged with a gap between them. The second line components 462 are also arranged with a gap between them. The first line components 461 and the second line components 462 are arranged in a cross-sectional arrangement. Thus, each of the spaces 45 is a quadrilateral.

[0040] The first line component 461 and the second line component 462 are crossed and combined at an interface 463. As in Fig. As shown in Figure 6, the first line component 461 and the second line component 462 cannot be combined at the interface 463. The first line components 461 and the second line components 462 can be interconnected (woven).

[0041] The frame 42 and the grid 44 are designed as an integrated molded part made of resin. This integrated molded part is a continuous component without connecting parts. The frame 42 and the grid 44 can also be made of a material other than resin.

[0042] The air conditioning unit 10 in this embodiment has two adjustment components 40. The airflows passing through the central driver opening 201 and the central passenger opening 203 are adjusted by the grille 44. This evens out the velocity distribution of the air blown from the central driver air outlet and the central passenger air outlet.

[0043] The grille 44 can exert resistance on the airflow passing through the central driver opening 201 and the central passenger opening 203. This reduces the amount of air blown out of the central driver air outlet and the central passenger air outlet, thereby reducing the air velocity.

[0044] According to the air conditioning unit 10 in this embodiment, the noise of the air being blown out is reduced compared to the air conditioning unit without the two adjustment components 40.

[0045] In the air conditioning unit 10 of this embodiment, the thickness of the linear components 46 and the spacing between adjacent linear components 46 can be changed. A target noise level can be reduced by changing the thickness and spacing. Additionally, the pressure loss of the airflow passing through each of the central driver opening 201 and the central passenger opening 203 can be regulated by changing the thickness and spacing. Second embodiment

[0046] As in Fig. As shown in Figure 7, a second embodiment is a modification of the first embodiment and the adjusting component 40 has a baffle plate 48. The further structure of the air conditioning unit 10 is the same as in the first embodiment.

[0047] Each of the adjustment components 40 has the frame 42, the grille 44 and two baffle plates 48. The baffle plate 48 is a plate component for influencing (disrupting) the airflow.

[0048] The grid 44 and the two impact plates 48 are arranged in a region enclosed by the frame 42. The two impact plates 48 are arranged in a circumferential portion that differs from a central portion within the region enclosed by the frame 42. The impact plates 48 are arranged on one side of the region enclosed by the frame 42. The grid 44 is arranged in a region enclosed by the frame 42, excluding the two impact plates 48. The frame 42, the grid 44, and the two impact plates 48 are formed as an integrated molded part made of resin. They can also be made of a material other than resin.

[0049] The grid region 47, in which the grid 44 is arranged, has the gaps 45. A baffle plate region 49, in which the baffle plates 48 are arranged, has no gaps. Thus, the openness ratio of the grid region 47 is greater than the openness ratio of the baffle plate region 49. The openness ratio is the ratio of the gaps formed by a component to the region in which the component is arranged. If the component does not form any gaps, the openness ratio is 0%. Thus, the grid region 47 is a region with lower resistance to the airflow than the baffle plate region 49. The baffle plate region 49 is a region with higher resistance to the airflow than the grid region 47. The grid 44 is a low-resistance component that exerts lower resistance to the airflow compared to the baffle plate 48.The baffle plate 48 is a high-resistance component that exerts a higher resistance on the airflow compared to the grille 44.

[0050] In this embodiment, the grid region 47 corresponds to the first region through which air flows. The baffle plate region 49 corresponds to the second region, which offers higher resistance to the airflow than the first region. The baffle plate 48 corresponds to the high-resistance component, which exerts higher resistance to the airflow than the resistance to the airflow in the first region. The grid 44 corresponds to the low-resistance component, which exerts lower resistance to the airflow than the resistance to the airflow in the second region.

[0051] In this embodiment, the entire area of ​​the grille region 47, including the grille 44 and the spaces 45, comprises more than half of the total opening area of ​​the openings 201 and 203 covered by the adjustment component 40. The grille region 47 is a continuous region. An area of ​​the baffle plate 48 that affects (disturbs) the airflow is larger than the average area of ​​each of the spaces 45.

[0052] In this embodiment, the same effect as in the first embodiment with grid 44 can be obtained. Furthermore, according to this embodiment, an effect described below can be obtained.

[0053] The air conditioning unit 10 is reduced in size, thereby reducing the size of the upper mixing passage 283 and the lower mixing passage 303. The upper mixing passage 283 and the lower mixing passage 303 are spaces where the cool air and warm air are mixed. In the case where the adjustment component 40 is not positioned to cover the central driver opening 201, in face mode the warm air and cool air pass through the central driver opening 201 without any mixing ratio. The central driver opening 201 has a region through which the warm air passes and a region through which the cool air passes. The warm air and cool air that have passed through the central driver opening 201 are blown out of the central driver air outlet through the duct as they are. This causes a large temperature fluctuation in the air that is blown out of the central driver air outlet.Therefore, the temperature fluctuation in the central driver air outlet is large. This large temperature fluctuation means that the difference between the minimum and maximum temperatures is significant. In the case where the central passenger air opening 203 is not covered by the adjustment component 40, the temperature fluctuation in the central passenger air outlet is also large.

[0054] In contrast, the air conditioning unit 10 in this embodiment has the adjustment component 40, which covers the central driver opening 201. The adjustment component 40 in this embodiment includes the baffle plate 48. The baffle plate region 49 has a higher resistance to the airflow compared to the grille region 47 without the baffle plate 48 in the region surrounded by the frame 42. Thus, the airflow passing through the central driver opening 201 can be affected (disturbed, turbulent).

[0055] In this embodiment, the baffle plate 48 is located in the region of the central driver's air outlet 201, through which warm air passes when the adjustment component 40 is not present. When warm and cold air pass through the central driver's air outlet 201, the baffle plate 48 directs the warm air to the region through which the cool air passes. This allows the warm and cool air to mix, thus reducing the temperature fluctuation of the air in the central driver's air outlet.

[0056] In the air conditioning unit 10 in this embodiment, the central occupant opening 203 has the adjustment component 40. This allows the temperature fluctuation of the air in the central occupant air outlet to be reduced.

[0057] In a comparative example, the upper mixing passage 283 and the lower mixing passage 303 are small, and the adjustment component 40 is not positioned to cover the central driver opening 201 and the central passenger opening 203. In this case, in face mode, warm air flows more strongly through the central driver opening 201 and the central passenger opening 203 than through the side driver opening 202 and the side passenger opening 204. Thus, the temperature of the air blown from the central driver air outlet and the central passenger air outlet is higher than the temperature of the air blown from the side driver air outlet and the side passenger air outlet. If the air is blown from the multiple air outlets with the same target temperature, the temperature difference of the air blown from different air outlets is large.In other words, the temperature fluctuation of the air blown from different air outlets is significant.

[0058] In contrast, in this embodiment, the air conditioning unit 10 is equipped with the adjustment component 40 to cover both the central driver opening 210 and the central passenger opening 203 in the face opening 20. The resistance to warm air is higher in this embodiment compared to a case where the adjustment component 40 is not arranged to cover the central driver opening 201 and the central passenger opening 203. Thus, the amount of warm air flowing through the central driver opening 201 and the central passenger opening 203 is reduced, and the amount of warm air flowing through the side driver opening 202 and the side passenger opening 204 is increased. The mixing ratio of the warm air and the cool air passing through the central driver opening 201, the side driver opening 202, the central passenger opening 203 and the side passenger opening 204 is homogenized.The temperature of the air blown from each of the central driver air outlet, the side driver air outlet, the central passenger air outlet, and the side passenger air outlet is standardized.

[0059] In this embodiment, the baffle plate 48 regulates the resistance to the airflow passing through the central driver opening 201 and the central passenger opening 203. By regulating the resistance, the flow of warm air in the openings 201, 202, 203 and 204 is controlled, and the mixing ratio of cool air and warm air is regulated.

[0060] As a result, the temperature fluctuation of the air flowing from different air outlets, including the central driver opening, the central passenger opening, the side driver opening, and the side passenger opening, is reduced.

[0061] The test results measured by the inventors are in Fig. 8 shown. Fig. Figure 8 shows the measurement results of the temperature fluctuation of the air in each of the openings and the temperature fluctuation of the air blown from the different air outlets. These results are compared between an air conditioning unit according to a comparative example and the air conditioning unit 10 according to this embodiment. The air conditioning unit of the comparative example differs from the air conditioning unit 10 of the embodiment in that the two adjustment components 40 of the air conditioning unit 10 in the comparative example do not have the two baffle plates 48. The further structure of the air conditioning unit in the comparative example is the same as that of the air conditioning unit 10 in this embodiment. The temperature fluctuation in the air outlet is the temperature fluctuation of the air in a face air outlet or in the central driver air outlet.The temperature variation between the air outlets is a temperature variation of the four face air outlets including the central driver air outlet, the central passenger air outlet, the side driver air outlet and the side passenger air outlet.

[0062] As can be seen from the result, which in Fig. As can be seen in Figure 8, according to the air conditioning unit 10 in this embodiment, the temperature fluctuation in the air outlet is reduced and the temperature fluctuation between the air outlets is reduced compared to the air conditioning unit in the comparison example.

[0063] In the air conditioning unit 10 in this embodiment, the two adjustment components 40 are arranged separately from the air conditioning housing 12. Thus, the reduction of the temperature fluctuation is achieved with the air conditioning unit 10 without modifying the shape of the air conditioning housing 12 according to a vehicle model, but by modifying the number or position of the baffle plate 48 of the adjustment component 40.

[0064] In the air conditioning unit 10 of this embodiment, the two baffle plates 48 are arranged in the circumferential part of the region enclosed by the frame 42. The region enclosed by the frame 42 corresponds to an opening region of the opening. In the absence of the adjustment component 40, the velocity of the air passing through the opening is higher in the center of the opening region. The velocity of the air passing through the opening is lower in the circumferential part of the opening region. Thus, in this embodiment, the baffle plate 48 is arranged in the region where the air velocity is low relative to the velocity distribution of the air passing through the opening without the adjustment component 40. Accordingly, the temperature fluctuation can be reduced while maintaining a sufficient air volume and reducing noise.

[0065] The position and number of baffle plates 48 are not limited to this embodiment. The position and number of baffle plates 48 can be suitably modified. For example, the baffle plate 48 can be positioned centrally in the region enclosed by the frame 42. By modifying the position of the baffle plate 48 and the area it occupies within the region enclosed by the frame 42, the temperature distribution of the air blown from the air outlet is regulated (controlled).

[0066] In this embodiment, the grid 44 and the impact plate 48 are designed as an integrated molded part. However, the grid 44 and the two impact plates 48 can be designed as separate components and can be connected to each other. Third example

[0067] As in Fig. As shown in Figure 9, in the third embodiment the two baffle plates 48 of the adjustment component 40 have several openings 48a. The further structure of the air conditioning unit 10 is the same as in the first embodiment.

[0068] The baffle plate 48 can have openings 48a. It can also have only one opening 48a. By forming one or more openings 48a in the baffle plate 48, the resistance to the airflow in the baffle plate region 49 is reduced. The resistance to the airflow in the opening covered by the adjusting component 40 is regulated. Fourth embodiment

[0069] As in Fig. As shown in Figure 10, the shape of the two adjustment components 40 in the fourth embodiment differs from that of the first embodiment. The remaining structure of the air conditioning unit 10 is the same as in the first embodiment.

[0070] Each of the two adjustment components 40 has a frame 42 and a grid 44a. The grid 44a is manufactured similarly to the grid 44 in the first embodiment; however, the grid 44a is arranged in a portion of the region enclosed by the frame 42. A region enclosed by the frame 42, excluding a grid region 47a, is a cavity. In other words, in each of the two adjustment components 40, a region enclosed by the frame 42 is defined by the grid region 47a and the cavity 50. The grid region 47a is a region in which the grid 44a is arranged. The cavity 50 is a region in which no component is arranged.

[0071] In this embodiment, the same effect is achieved as in the first embodiment with the grille 44. Additionally, the opening ratio of the cavity 50 is higher than the opening ratio of the grille region 47a. Thus, the cavity 50 is a region where the resistance to the airflow is lower than in the grille region 47a. The grille region 47a is a region where the resistance to the airflow is higher than in the cavity 50. The grille 44a is the high-resistance component that exerts a higher resistance to the airflow compared to the cavity 50. Therefore, the same effect as in the first embodiment is achieved in this embodiment.

[0072] In this embodiment, the cavity 50 corresponds to the first region through which air flows. The grid region 47a corresponds to the second region, which offers higher resistance to the airflow than the first region. The grid 44a corresponds to the high-resistance component, which exerts a higher resistance to the airflow than the resistance to the airflow in the first region. Fifth embodiment

[0073] As in Fig. As shown in Figure 11, the shapes of the two adjustment components 40 in the fifth embodiment differ from those in the first embodiment. The rest of the structure of the air conditioning unit 10 is the same as in the first embodiment.

[0074] Each of the two adjustment components 40 has a frame 42 and two impact plates 48. The two impact plates 48 are arranged in a portion of the region enclosed by the frame 42. The region enclosed by the frame 42 is defined by the impact plate region 49 and the cavity 50. In other words, in each of the two adjustment components 40, the cavity 50 is formed in the region enclosed by the frame 42, with the exception of the impact plate region 49. The cavity 50 is a region in which no component is arranged.

[0075] In this embodiment, the opening ratio of the cavity 50 is higher than the opening ratio of the baffle plate region 49. The cavity 50 is a region with lower resistance to the airflow than the baffle plate region 49. The baffle plate region 49 is a region with higher resistance to the airflow than the cavity 50. The baffle plate 48 is the high-resistance component that exerts a higher resistance to the airflow compared to the cavity 50. In this embodiment, the same effect is achieved as in the second embodiment.

[0076] In this embodiment, the cavity 50 corresponds to the first region through which air flows. The baffle plate region 49 corresponds to the second region, which has a higher resistance than the first region. The baffle plate 48 corresponds to the high-resistance component, which exerts a higher resistance on the airflow than the resistance on the airflow in the first region. Sixth embodiment

[0077] As in Fig. As shown in Figure 12, the shapes of the two adjustment components 40 in the sixth embodiment differ from those of the first embodiment. The rest of the structure of the air conditioning unit 10 is the same as in the first embodiment.

[0078] Each of the two adjustment components 40 has a frame 42, a first grid 44, and a second grid 52. The first grid 44 and the second grid 52 are arranged in the region enclosed by the frame 42. The first grid 44 is identical to the grid 44 in the second embodiment. A first grid region in which the first grid 44 is arranged is identical to the grid region 47 in the second embodiment.

[0079] The second grid 52 has several line elements 46 arranged to form the spaces 45 as in the first grid 44. The spacing between adjacent line elements 46 in the second grid 52 is narrower (smaller) than in the first grid 44. The adjacent line elements 46 are arranged more densely (closer together) in the second grid 52. The spaces 45 in the second grid 52 are smaller than in the first grid 44.

[0080] In this embodiment, the same effect as in the first and second embodiments is achieved by arranging the first grille 44 and the second grille 52. Additionally, the opening ratio of the first grille region 47 is higher than the opening ratio of the second grille region 53, in which the second grille 52 is located. The first grille region 47 offers lower resistance to the airflow than the second grille region 53. The second grille region 53 offers higher resistance to the airflow than the first grille region 47. The first grille 44 is the low-resistance component, exerting lower resistance to the airflow compared to the second grille 52. The second grille 52 is the high-resistance component, exerting higher resistance to the airflow compared to the first grille 44.In this embodiment, the same effect is achieved as in the second embodiment.

[0081] In this embodiment, the first grid region 47 corresponds to the first region through which air flows. The second grid region 53 corresponds to the second region, which offers higher resistance to the airflow than the first region. The second grid 52 corresponds to the high-resistance component, which exerts higher resistance to the airflow than the resistance to the airflow in the first region. The first grid 44 corresponds to the low-resistance component, which exerts lower resistance to the airflow than the resistance to the airflow in the second region. Further examples of implementation

[0082] In the first to fourth and sixth embodiments, the spaces 45 formed by the grid 44, the first grid 44 and the second grid 52 are rectangular. However, each space can have a shape other than a quadrilateral.

[0083] For example, the grid 44, the first grid 44 and the second grid 52 can be modified to form a network component 54 that creates circular gaps 55, as in Fig. Figure 13 shows that in this case, the circular spaces 55 are several air passages through which air passes (flows). The network component 54 is a partition that defines the air passages.

[0084] As in Fig.As shown in Figure 14, the grid 44, the first grid 44, and the second grid 52 can be modified to form a network component 56 that creates hexagonal spaces 57. In this case, the hexagonal spaces 57 are multiple air passages through which air passes (flows). The network component 56 is a partition that defines the air passages.

[0085] In the preceding embodiments, the two openings 201, 203 in the four openings 201, 202, 203, and 204 of the face openings 20 have the adjustment components 40. However, this is not limited to this case. The adjustment components 40 can be arranged to cover one of the four openings 201, 202, 203, and 204. For example, the adjustment components 40 can be arranged to cover all four openings 201, 202, 203, and 204. In this case, it is preferred that the resistance value on the airflow between the central openings 201, 203 and the lateral openings 202, 204 is different, as in the second embodiment. Thus, the temperature fluctuation of the air blown from different air outlets is reduced, as in the second embodiment.

[0086] In the preceding embodiments, the adjusting component 40 is arranged to cover the face opening 20. However, the adjusting component 40 can also be arranged to cover other openings. This achieves the same effect as in the preceding embodiments.

The present disclosure includes various examples of modifications and modifications within the equivalence range.

[0088] According to the first aspect of the invention, which covers some or all of the foregoing embodiments, an air conditioning unit comprises an air conditioning housing, a cooler, a heater (a heating device), and an adjustment component. The adjustment component has a first region through which air flows and a second region that exerts a higher resistance to the airflow than the first region.

[0089] According to the second perspective, the second region has a high-resistance component that exerts a greater resistance on the airflow than the first region. Therefore, the resistance to the airflow in the second region is higher than the resistance to the airflow in the first region.

[0090] According to the third aspect, the region features a low-drag component that exerts less resistance on the airflow than the second region. The low-drag component can be located in the first region.

[0091] According to the fourth aspect, the low-resistance component is a partition that defines several air passages through which air flows. The high-resistance component is a plate component with a part designed to influence (disrupt) the airflow. In particular, the components described in the fourth embodiment can be used as the low-resistance component and the high-resistance component.

[0092] Accordingly, the partition regulates the airflow passing through the opening. This evens out the velocity distribution of the air blown from the air outlets located in the cabin. Additionally, the partition exerts resistance on the airflow passing through the opening. This reduces the amount of air blown from the air outlet into the cabin and thus lowers the air velocity.

[0093] This results in a reduction in the noise of the expelled air compared to the case without the adjustment component.

[0094] According to the fifth point, an air conditioning unit comprises an air conditioning housing and an adjustment component. The adjustment component has a partition that defines several air passages through which air flows.
