Description

[0001] This application is a divisional application of application number 201680038323.7, entitled “Device for heating, ventilating and / or air conditioning the interior of a vehicle”, and the application date is June 17, 2016. Technical Field

[0002] The invention relates to a device for heating, ventilating and / or air-conditioning a vehicle interior, comprising: an air mixing chamber having a hot air inlet for supplying hot air into the air mixing chamber, a cold air inlet for supplying cold air into the air mixing chamber, and a first mixed air outlet and a second mixed air outlet for discharging mixed air from the air mixing chamber to different areas of the vehicle interior. Each mixed air outlet can be assigned a control flap for controlling the mixed air mass flow at the respective mixed air outlet. Background Art

[0003] In modern vehicle air conditioners, various air distribution modes are currently defined. For example, in winter mode, the air mass flow rate of the heater floor outlet is greater than the air mass flow rate of the air space above the heater floor outlet, while in summer mode of the vehicle air conditioner, the air mass flow rate of the heater floor outlet is lower than the air mass flow rate of the air space above it.

[0004] In order to change from one air distribution mode to a different air distribution mode, the control flaps assigned to the mixed air outlet are adjusted in an appropriate manner, thereby changing the air flow conditions in the air mixing chamber. However, different air flow conditions can lead to undesirable changes in the air temperature at the mixed air outlet. For example, in the case of a temperature setting specified by the position of the mixed air flaps in summer mode, the vehicle air conditioner is set so that the mixed air flowing to the heater base outlet is slightly warmer than the mixed air supplied to the air space located above it. If the vehicle air conditioner is switched to winter mode with the same temperature setting, the air mass flow at the mixed air outlet is changed in the desired manner by the predetermined adjustment of the control flaps. Due to this adjustment of the air mass flow, in the case of conventional vehicle air conditioners, the temperature conditions at the mixed air outlet also change in an undesirable manner, for example, a temperature difference between the mixed air supplied to the heater base outlet and the air space located above it. Summary of the invention

[0005] The object of the present invention is to provide a device for heating, ventilating and / or air-conditioning the interior of a vehicle, in which, in the case of an air mass inflow into different zones of the vehicle interior, the device can be adapted with little effort to the desired operating mode without significantly changing the preset temperature differences between the different interior zones.

[0006] According to the invention, this object is achieved by a device for heating, ventilating and / or air-conditioning a vehicle interior, the device having an air mixing chamber, the air mixing chamber having a hot air inlet for supplying hot air into the air mixing chamber, a cold air inlet for supplying cold air into the air mixing chamber, and a first mixed air outlet and a second mixed air outlet for discharging mixed air from the air mixing chamber into different areas of the vehicle interior, a first control flap assigned to the first mixed air outlet for controlling the mixed air mass flow at the first mixed air outlet, and a second control flap assigned to the second mixed air outlet for controlling the mixed air mass flow at the second mixed air outlet, wherein one of the air inlets is assigned an adjustable air guide element for throttling and / or deflecting the hot or cold air flowing through the one air inlet into the air mixing chamber. The change of the air flow state in the air mixing chamber during the change of the operating mode by adjusting the control flap is influenced by the adjustable air guide element so that the air temperature and / or the existing temperature difference at the mixed air outlet does not change or changes only insignificantly.

[0007] Furthermore, the device according to the invention can be switched between summer and winter mode, preferably automatically by the electronic control unit.

[0008] In one embodiment of the device, an adjustable air guiding element is assigned to the cold air inlet and can throttle and / or deflect the cold air flowing through the cold air inlet into the air mixing chamber.

[0009] Furthermore, in particular, a mixed air flap is provided which sets the hot air supplied via the hot air inlet and the cold air supplied via the cold air inlet for temperature control of the mixed air.

[0010] Here, the mixing air flap can be located upstream of a heating element through which air flows in order to control the amount of air flowing through the heating element to the hot air inlet, wherein the mixing air flap can protrude both into an inlet duct for air flowing to the heating element and into a cold air duct leading to the cold air inlet in order to change the duct cross-section, the inlet duct being used for air flowing to the heating element and the cold air duct leading to the cold air inlet.

[0011] According to another embodiment, the first mixed air outlet and the second mixed air outlet are assigned to the rear seat of the vehicle. In this case, preferably a mixed air duct is linked to each mixed air outlet, and the mixed air duct extends from the corresponding mixed air outlet until the air diffuser in the rear seat of the vehicle.

[0012] The first mixed air outlet is preferably assigned to a heater base outlet in the vehicle interior and the second mixed air outlet is assigned to an air space in the vehicle interior located above the heater base outlet.

[0013] According to another embodiment of the device for heating, ventilating and / or air-conditioning a vehicle interior, two first mixed air outlets spaced apart from each other are provided, wherein the second mixed air outlet is arranged between the two first mixed air outlets. In particular, the two first mixed air outlets in the vehicle interior are arranged laterally opposite each other, and the second mixed air outlet is arranged approximately centrally.

[0014] In this embodiment, a deflector can be provided between the first mixed air outlet and the second mixed air outlet in each case.A stable air mass flow at the mixed air outlet can be provided in a reliable and reproducible manner and at low cost via such a deflector.

[0015] Furthermore, in this embodiment, two first mixed air outlets can each be assigned a pivotable first control flap, wherein the two first control flaps are rotationally and jointly connected via an axle. As a result of this rotationally joint connection, the two first control flaps can advantageously be adjusted by only one flap drive.

[0016] Preferably, the adjustable air guiding element is mechanically coupled to the first control flap and / or the second control flap, so that the air guiding element is adjusted together with the first control flap and / or the second control flap. Due to this mechanical coupling of the adjustable air guiding element to the control flap, a separate drive for adjusting the air guiding element can be omitted. This results in a very compact and cost-effective construction of the device for heating, ventilating and / or air-conditioning the vehicle interior.

[0017] According to a particularly simple structural embodiment variant, the adjustable air guiding element is rotationally coupled to the shaft, which also rotationally couples the two first control flaps to one another.

[0018] Furthermore, a second pivotable control flap mechanically coupled to the shaft can be assigned to the second mixed air outlet. In this way, all control flaps and, if applicable, also adjustable air guiding elements can be actuated by only one drive device.

[0019] According to another embodiment of the device for heating, ventilating and / or air-conditioning the interior of a vehicle, the air guiding element is arranged between the cold air inlet and the second mixed air outlet in the air mixing chamber. The cold air flow to the second mixed air outlet and thus the air temperature at the second mixed air outlet can be influenced in a desired manner via the air guiding element with little effort.

[0020] According to a further embodiment, the air mixing chamber is defined by a housing, wherein the housing has a throttle projection near the adjustable air guiding element for setting a desired flow cross section between the housing and the air guiding element. The air guiding effect of the adjustable air guiding element can be varied, in particular increased, with little effort by such a throttle projection on the housing.

[0021] The present invention also relates to a flap assembly for the above-mentioned device for heating, ventilating and / or air-conditioning the interior of a vehicle, comprising a pivotable first control flap, a pivotable second control flap and an adjustable air guiding element, wherein the first control flap and the second control flap are mechanically connected via a connecting element so that the second control flap is closed during the opening of the first control flap and is opened during the closing of the first control flap, and wherein the air guiding element is mechanically connected to the first control flap and / or the second control flap, in particular rotationally and combinedly connected.

[0031] Figure 1 The device 10 is shown as an air conditioner for heating, ventilating and / or air-conditioning a vehicle interior 12, which has an evaporator 14 through which air can flow for generating cold air 16 which can be supplied from the vehicle interior 12, and a heating element 18 through which air can flow for generating hot air 20 which can be supplied from the vehicle interior 12. The cold air 16 and the hot air 20 are supplied, on the one hand, to an air mixing chamber 22 which air-conditions a front region of the vehicle interior 12 via a mixed air outlet 24, and, on the other hand, to an air mixing chamber 26 which air-conditions a front region of the vehicle interior 12 via mixed air outlets 28, 30 (see also Figure 2 and 3 ) air conditioning the rear seat area of ​​the vehicle interior 12. With reference to the heating element 18, two separate bypass ducts are provided, in particular, one of which conducts the cold air 16 to an air mixing chamber 22, which is assigned to the front area of ​​the vehicle interior 12, while bypassing the heating element 18, and the other of which conducts the cold air 16 to an air mixing chamber 26, which is assigned to the rear seat area of ​​the vehicle interior 12, while bypassing the heating element 18.

[0032] Figure 2 and Figure 3 Shown according to Figure 1 Schematic detailed section of an air conditioner in the region of an air mixing chamber 26 assigned to the rear vehicle seats. Although the invention is described below with reference only to the air mixing chamber 26, it is clear to a person skilled in the art in the field of vehicle air conditioning technology that the described measures can be applied in an analogous manner to the air mixing chamber 22, wherein the advantages indicated below for the rear region of the vehicle interior 12 also result in the air conditioning of the front region of the vehicle interior 12.

[0033] according to Figure 2 and Figure 3, a device 10 for heating, ventilating and / or air-conditioning a vehicle interior 12 comprises an air mixing chamber 26 having a hot air inlet 32 ​​for supplying hot air 20 into the air mixing chamber 26; a cold air inlet 34 for supplying cold air 16 into the air mixing chamber 26; and a first mixed air outlet 28 and a second mixed air outlet 30 for discharging mixed air 40 from the air mixing chamber 26 into different (rear seat) areas of the vehicle interior 12; a first control flap 42 assigned to the first mixed air outlet 28 to control the mixed air mass flow at the first mixed air outlet 28; and a second control flap 44 assigned to the second mixed air outlet 30 to control the mixed air mass flow at the second mixed air outlet 30.

[0034] Furthermore, an adjustable air guide element 46 is assigned to exactly one of the air inlets 32 , 34 for throttling and / or deflecting the hot air 20 or the cold air 16 flowing through the exactly one air inlet 32 ​​, 34 into the air mixing chamber 26 . Figure 2 and 3 In a preferred embodiment variant, an adjustable air guide element 46 is specifically assigned to the cold air inlet 34 in order to throttle and / or deflect the cold air 16 flowing through the cold air inlet 34 into the air mixing chamber 26 .

[0035] In the exemplary embodiment shown, the adjustable air guide element 46 is a pivotable flap of the spoiler type, which is arranged in the air mixing chamber 26 or on the edge of the air mixing chamber 26 and the cold air inlet 34. Figure 2 and 3 The air guide element 46 is formed as a separate flap with its own actuation drive (not shown), but can optionally also be mechanically coupled to at least one of the control flaps 42, 44 (see Figures 5 to 8 ).

[0036] Furthermore, a mixing air flap 48 is provided upstream of the air inlets 32, 34 of the air mixing chamber 26, which sets the ratio between the hot air 20 supplied via the hot air inlet 32 ​​and the cold air 16 supplied via the cold air inlet 32 ​​for temperature control of the mixed air 40. Specifically, the mixing air flap 48 is located upstream of the heating element 18 (through which the air flows) in order to control the amount of air flowing through the heating element 18 to the hot air inlet 32 ​​(for the rear seats of the vehicle), wherein the mixing air flap 48 can protrude into both the inflow duct 50 for the air flowing to the heating element 18 and the cold air duct 52 leading to the cold air inlet 34 in order to change the duct cross section.

[0037] As already mentioned, in Figure 2 and Figure 3 The mixed air outlets 28, 30 shown in FIG. 1 are assigned to the vehicle rear seats for discharging the mixed air 40 from the air mixing chamber 26 into different areas of the vehicle interior 12. Specifically, the first mixed air outlet 28 is assigned to the heater base outlet 54, and the second mixed air outlet 30 is assigned to the air space 56 located above the heater base outlet 54. Moreover, the mixed air ducts 58, 60 are linked to each of the mixed air outlets 28, 30, and the mixed air ducts 58, 60 extend from the corresponding mixed air outlets 28, 30 up to an air diffuser (not shown) in the heater base outlet 54 or the air space 56 of the vehicle rear seats.

[0038] according to Figure 2 The device 10 for heating, ventilating and / or air-conditioning the interior of a vehicle, which is implemented as an air conditioner, is in its winter mode, while Figure 3 The vehicle air conditioner is shown in its summer mode.

[0039] In comparison Figure 2 and Figure 3 In the case of , it is clear that in winter mode the air mass flow is directed to a greater extent to the first mixed air outlet 28 which is assigned to the heater floor outlet 54 in the rear vehicle seats, while in summer mode the air mass flow is supplied to a greater extent to the second mixed air outlet 30 which is assigned to the air space 56 above the heater floor outlet 54 in the rear vehicle seats. This change can be made fully automatically, for example by means of an actuating motor. Figure 2 and Figure 3 The position of the mixing air flaps in the vehicle remains unchanged, so similar, ideally almost identical, temperature ratios should be set in the rear seats of the vehicle.

[0040] To illustrate the temperature conditions in the rear seats of the vehicle, Figure 4 Two diagrams are shown in which the air temperature T at the mixed air outlet 28, 30 is plotted as a function of the position s of the mixed air flap 48 in each case, wherein the left diagram is assigned to the winter mode of the vehicle air conditioner and the right diagram is assigned to the summer mode of the vehicle air conditioner. The position s of the mixed air flap 48 is expressed in percentages, wherein s=0% corresponds to closing of the inflow duct 50 (and thus complete release of the cold air duct 52) ​​and s=100% corresponds to complete release of the inflow duct 50 (and thus closing of the cold air duct 52). In order to compare the winter mode with the summer mode, the position s of the mixed air flap 48 is expressed in percentages, wherein s=0% corresponds to closing of the inflow duct 50 (and thus complete release of the cold air duct 52) ​​and s=100% corresponds to complete release of the inflow duct 50 (and thus closing of the cold air duct 52). Figure 2 and Figure 3 The central setting position of the blending damper flap 48 is emphasized in FIG. 5 , in which both the inflow duct 50 and the cold air duct 52 are relieved to approximately 50%.

[0041] In accordance with Figure 4 In the figures, two temperature curves 62, 64 are shown in each case, wherein the temperature curve 62 indicates the temperature at the first mixed air outlet 28 assigned to the heater floor outlet 54 for the rear vehicle seats, and the temperature curve 64 indicates the temperature distribution at the second mixed air outlet 30 assigned to the air space 56 in the rear vehicle seats. Figure 4 , left-hand figure), shows the effect of the air guiding element 46, wherein the temperature curve 64 of the air space 56 assigned to the rear seats of the vehicle is represented with the air guiding element 46 (continuous curve) and without the air guiding element 46 (dashed line). In other words, this means that the shaded area between the continuous temperature curve and the dashed temperature curve 64 shows the temperature control performed by the guiding element 46 in the winter mode.

[0042] A comparison of the air temperatures T at the first mixed air outlet 28 and the second mixed air outlet 30 at the center position s≈50% of the mixed air flap 48 shows the overall temperature level in winter mode ( Figure 4 , left figure) increases slightly (which is entirely expected), but the temperature difference between the two mixed air outlets 28, 30 remains essentially unchanged, according to Figure 4 In the absence of the air guide element 46, the second mixed air outlet 30 throttled by the second control flap 44 will be over-acted by the cold air 16 in the winter mode, and the cold air 16 will flow in through the cold air outlet 34, which will lead to an undesirable temperature drop at the second mixed air outlet 30 (see Figure 4 , the dotted temperature curve 64 in the left figure).

[0043] according to Figure 4 , the air guiding element 46 influences only the temperature profile 64 and not the temperature profile 62. This is due to the fact that in the exemplary embodiment, the adjustable air guiding element 46 extends upstream of the second mixed air outlet 30 but not upstream of the first mixed air outlet 28 in the air mixing chamber 26.

[0044] exist Figures 5 to 8 A corresponding specific exemplary embodiment of an apparatus 10 for heating, ventilating and / or air conditioning a vehicle interior 12 is shown in more detail in FIG. 1 and will be described in more detail below.

[0045] according to Figure 5, two first mixed air outlets 28 spaced apart from each other are provided, wherein the second mixed air outlet 30 is arranged between the two first mixed air outlets 28. This corresponds to a normal ventilation structure in a rear seat of a vehicle, wherein the first mixed air outlets 28 assigned to the heater floor outlet 54 are arranged laterally oppositely (e.g., behind a driver or passenger seat), and the second mixed air outlet 30 assigned to the air space 56 is arranged approximately centrally (e.g., in a center console).

[0046] like Figure 5 As shown, a deflector 66 is provided in each case between the first mixed air outlet 28 and the second mixed air outlet 30 in order to prevent mixing and mutual influencing of the mixed air flows.

[0047] In addition, Figure 5 In each case, a first pivotable control flap 42 is assigned to two first mixed air outlets 28 and a second pivotable control flap 44 is assigned to the second mixed air outlet 30, wherein the control flaps 42, 44 in the present exemplary embodiment are mechanically connected to one another and respectively form a connected flap assembly 68.

[0048] The flap assembly 68 is shown in perspective detail. Figure 6 The two first control flaps 42 are here rotationally connected together by means of a shaft 70, while the pivotable second control flap 44 is mechanically coupled to the shaft 70, in particular kinematically coupled to the shaft 70, via a connecting element 72. The two first control flaps 42 are preferably coupled in the opposite direction to the second control flaps 44, so that the second control flaps 44 are closed during the opening of the first control flaps 42 and are opened during the closing of the first control flaps 42.

[0049] The adjustable air guiding element 46 is particularly preferably also mechanically coupled to the first control flap 42 and / or the second control flap 44, so that the air guiding element 46 is adjusted together with the first control flap 42 and / or the second control flap 44. Figure 6 The adjustable air guiding element 46 is in particular rotationally connected to the shaft 70 and correspondingly also rotationally connected to the first control flap 42 .

[0050] Thus, the pre-installable flap assembly 68 comprises a device 10 for, in the present exemplary embodiment, heating, ventilating and / or air-conditioning a vehicle interior 12, a pivotable first control flap 42, a pivotable second control flap 44, and an adjustable air guiding element 46, wherein the first control flap 42 and the second control flap 44 are mechanically coupled via a connecting element 72, such that the second control flap 44 is closed during opening of the first control flap 42 and is opened during closing of the first control flap 42. Furthermore, the air guiding element 46 is rotationally and integrally connected to the first control flap 42.

[0051] exist Figure 7 and 8 Detailed cross-sections of a device 10 for heating, ventilating and / or air-conditioning a vehicle interior 12 are shown in each case through an air mixing chamber 26, the air mixing chamber 26 having a Figure 6 The installed flap assembly 68, wherein Figure 7 shows a section in the region of the second control flap 44 , Figure 8 4 shows a cross section in the region of the first control flap 42. It is clear here that the adjustable air guide element 46 is arranged between the cold air inlet 34 and the second mixed air outlet 30 in the air mixing chamber 26. However, the air mass flow at the first mixed air outlet 28 is not influenced by the air guide element 46 or is only influenced insignificantly by the air guide element 46 (see Figure 8 ).

[0052] according to Figure 7 The air mixing chamber 26 is defined by a housing 74 , wherein the housing 74 has one or more throttle projections 76 near the adjustable air guiding element 46 for setting a desired flow cross section between the housing 74 and the air guiding element 46 . Figure 7 Also shown is an optional air guide duct 78 which is adjacent to the hot air inlet 32 ​​and guides the hot air 20 from there directly to the second mixed air outlet 30 .

[0053] These optional additional measures, such as the throttle projection 76 and the air guide duct 78, should ultimately support the action of the mixed air flap 48 and keep the desired temperature difference between the first mixed air outlet 28 and the second mixed air outlet 30 substantially constant, regardless of the operating mode of the vehicle air conditioner. In particular, in the winter mode of the vehicle air conditioner, an undesirable drop in the air temperature at the second mixed air outlet 30 should be prevented (see Figure 4 , dashed temperature curve 64).
