Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to an air supply structure and an air conditioning device. Background Art

[0002] The automobile air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the car. It can provide a comfortable riding environment for passengers, reduce the fatigue of the driver, and improve driving safety. It is an essential component in the car. The automobile air conditioning HVAC assembly integrates multiple functions such as heating, ventilation and air conditioning refrigeration. The traditional HVAC assembly adopts a structure with separate cold air duct and warm air duct. This structure requires a large space, a lot of materials, and a relatively complex structure. In order to meet the air volume conditions, the corresponding structural design requirements of the cold and warm air doors are strict, and it is time-consuming and laborious to change. At the same time, today's automobile designs are becoming more and more sophisticated, and the functions are becoming more and more complicated. The space left for automobile air conditioning assemblies will be less and less, and the traditional air conditioning structure has begun to be unsuitable for the requirements of today's automobiles.

[0003] The prior art discloses an air outlet structure of an automobile air conditioner, which includes a casing and a rotary damper arranged in the casing, and a plurality of vents are arranged in sequence along the circumferential direction on the outer side of the rotary damper. The casing is provided with a face-blowing vent, a foot-blowing vent and a glass-blowing vent, and the face-blowing vent, the foot-blowing vent and the glass-blowing vent are also arranged in sequence along the circumference of the rotary damper. When the rotary damper rotates to different angles, it can be connected with the corresponding vents on the casing through different vents to discharge the introduced air from the corresponding vents on the casing. Among them, since the vents are arranged in the circumferential direction of the rotary damper, in order to facilitate communication, the face-blowing vent, the foot-blowing vent and the glass-blowing vent are also arranged in sequence along the circumferential direction of the rotary damper, so that the casing occupies a large space in the circumferential direction of the rotary damper, resulting in a large local volume of the air outlet structure, which is not conducive to the compact design of the air outlet structure.

[0052] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0053] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0056] See also Figure 1-7 As shown, according to an embodiment of the utility model, an air supply structure is provided, which includes a housing 13 and a rotary damper 3, and the rotary damper 3 can be driven to rotate around its own axis. The outer side of the rotary damper 3 is provided with an air guide groove 323, and the opening of the air guide groove 323 extends along the circumference of the rotary damper 3. The rotary damper 3 is provided with a vent 320 connected to the air guide groove 323 on at least one side in the axial direction. In some embodiments, the rotary damper 3 can be provided with a vent 320 connected to the air guide groove 323 on both sides in the axial direction.

[0057] The aforementioned rotary damper 3 is disposed on the housing 13, and the rotary damper 3 is used to cooperate with the housing 13 to introduce wind through a partial opening area of ​​the wind guide slot 323 when rotating, and to guide the introduced wind out of another partial opening area of ​​the wind guide slot 323 when rotating to a first angle (such as Figure 8 and Fig.12 ), and when the vent is rotated to a second angle, the introduced wind is guided out from the vent 320 alone (as shown in FIG. Fig.10 shown).

[0058] In the above example, the opening of the air guide groove 323 in the circumferential direction of the rotary damper 3 is equivalent to a partial vent in the prior art, and the opening of the air guide groove 323 in the circumferential direction of the rotary damper 3 cooperates with the vent 320 in the axial direction of the rotary damper 3, so that the vent 320 is distributed in both the circumferential and axial directions of the rotary damper 3. Compared with the solution in the prior art that all vents 320 are arranged in the circumferential direction of the rotary damper 3, the technical solution of the utility model can utilize the space in both the circumferential and axial directions of the rotary damper 3 by distributing the vents 320 in the circumferential direction of the rotary damper 3, avoiding the problem of a large local volume of the air supply structure caused by only utilizing the space in the circumferential direction of the rotary damper 3, so that the overall structure of the air supply structure can be distributed more evenly and compactly.

[0059] In order to achieve the purpose that the aforementioned rotary damper 3 can cooperate with the housing 13 to guide the wind from another opening area of ​​the wind guide slot 323 or the vent 320 when rotating to different angles, in some embodiments, such as Figures 4 to 6 As shown, the aforementioned housing 13 may have a accommodating cavity 14, and the aforementioned rotary damper 3 is located in the accommodating cavity 14. Among them, the rotary damper 3 is provided with a first rib plate structure 33 and a second rib plate structure 34 spaced apart in the circumferential direction, and the first rib plate structure 33 and the second rib plate structure 34 may both be fixed on the rotary damper 3, for example, integrally formed on the rotary damper 3. The first rib plate structure 33 and the second rib plate structure 34 cooperate with each other to separate the rotary damper 3 into a closed area 31 and an air guide area 32 in the circumferential direction. The aforementioned air guide groove 323 is located in the air guide area 32. The aforementioned housing 13 also has an air outlet 15 connected to the accommodating cavity 14. Among them, the first rib plate structure 33 and the second rib plate structure 34 respectively cooperate with the cavity wall of the accommodating cavity 14, so that when the rotary damper 3 rotates to the first angle, another part of the opening area of ​​the air guide groove 323 is connected to the air outlet 15 (such as Figure 8 and Fig.12 and when the rotary damper 3 is rotated to a second angle, the opening area of ​​the air guide groove 323 is separated from the air outlet 15 (as shown in Fig.10 shown).

[0060] In the above example, when the rotary damper 3 rotates to the first angle, another part of the opening area of ​​the air guide groove 323 is connected to the air outlet 15, so that the air supply structure can discharge air through the air outlet 15. When the rotary damper 3 rotates to the second angle, the first rib plate structure 33 and the second rib plate structure 34 cooperate with the cavity wall of the accommodating cavity 14 to separate the opening area of ​​the air guide groove 323 from the air outlet 15, so that the air outlet structure cannot discharge air through the air outlet 15, so that the air outlet structure can discharge the introduced air from the vent 320 alone.

[0061] The first rib plate structure 33 and the second rib plate structure 34 are both rib plates, which facilitates processing.

[0062] like Figure 3 As shown, the rotary damper 3 can be roughly cylindrical, and the rotary damper 3 has a central rotating shaft 30, and the rotary damper 3 can be rotated by the central rotating shaft 30. The rotary damper 3 is divided into two parts, a closed area 31 and a wind guide area 32, by a first rib plate structure 33 and a second rib plate structure 34 in the circumferential direction. The projection angle range of the wind guide area 32 in the axial direction of the rotary damper 3 is greater than the projection angle range of the closed area 31 in the axial direction of the rotary damper 3. The maximum angle range of the closed area 31 satisfies: when the rotary damper 3 rotates to a certain angle, the closed area 31 can simultaneously cover the first air outlet 101 and the second air outlet 102 described below. Since the wind guide area 32 needs to connect the air outlet duct 105 with each downstream air outlet, the angle range of the wind guide area 32 is larger than that of the closed area 31.

[0063] like Figure 3 As shown, the aforementioned rotary damper 3 has a first baffle 321 at one end in the axial direction, and a second baffle 322 at the other end in the axial direction. The aforementioned first main rib 311 and the second main rib 312 are both in contact with the first baffle 321 at one end in the axial direction of the rotary damper 3, and the aforementioned other ends in the axial direction of the rotary damper 3 are both in contact with the second baffle 322. The aforementioned vent 320 is arranged on the first baffle 321 and / or the second baffle 322. The aforementioned air guide groove 323 is located in the air guide area 32, and a reinforcing rib 325 may be provided in the air guide groove 323 to enhance the strength of the rotary damper 3. The reinforcing rib 325 is preferably parallel to the first baffle 321 and the second baffle 322. The number of reinforcing ribs 325 may be more than two, and they are arranged in sequence.

[0064] The aforementioned air outlet 15 may be a single air outlet, or a combined air outlet composed of two or more small air outlets. The following is an example in which the air outlet 15 is a combined air outlet. Figure 6As shown, the aforementioned air outlet 15 may include a first air outlet 101 and a second air outlet 102, and the first air outlet 101 and the second air outlet 102 may be arranged at intervals on the housing 13. Both the first air outlet 101 and the second air outlet 102 are connected to the accommodating cavity 14. When the air supply structure of the utility model is applied to an automobile air conditioner, the aforementioned first air outlet 101 may be a face-blowing air outlet, the aforementioned second air outlet 102 may be a glass-blowing air outlet, and the aforementioned vent 320 discharges air through the foot-blowing air outlet on the housing 13.

[0065] The aforementioned first angle includes a first A angle and a first B angle. Figure 8 As shown, when the rotary damper 3 rotates to the first angle A, the air outlet 15 is connected to another part of the opening area of ​​the air guide groove 323 only through the first air outlet 101, and the second air outlet 102 is not connected to the opening of the air guide groove 323. Fig.12 As shown, when the rotary damper 3 rotates to the first angle B, the air outlet 15 is connected to another part of the opening area of ​​the air guide groove 323 only through the second air outlet 102, and the first air outlet 101 is not connected to the air guide groove 323. Fig.10 As shown, when the rotary air door 3 rotates to the second angle, the opening area of ​​the air guide groove 323 is separated from both the first air outlet 101 and the second air outlet 102 .

[0066] In the above example, if Figure 8 As shown, when the rotary damper 3 rotates to the first angle A, another part of the opening area of ​​the air guide slot 323 is connected to the first air outlet 101 separately, so that the air supply structure can discharge air through the first air outlet 101. Fig.12 As shown, when the rotary damper 3 rotates to the first angle B, the other opening area of ​​the air guide slot 323 is connected to the second air outlet 102 separately, so that the air supply structure can discharge air through the second air outlet 102. Fig.10 As shown, when the rotary damper 3 rotates to the second angle, the first rib plate structure 33 and the second rib plate structure 34 cooperate with the cavity wall of the accommodating cavity 14 to separate the opening area of ​​the air guide groove 323 from the first air outlet 101 and the second air outlet 102, so that the air outlet structure cannot discharge air through the first air outlet 101 and the second air outlet 102, so that the air outlet structure can guide the introduced air out from the vent 320 alone for discharge.

[0067] It should be noted that when the air supply structure of the utility model is applied to a car air conditioner, the mode of the air supply structure when the rotary air door 3 rotates to the first angle A can be called the face blowing mode (such as Figure 8 The mode of the air supply structure when the rotary damper 3 rotates to the first angle B can be called the glass blowing mode (as shown in FIG. Fig.12The mode of the air supply structure when it is rotated to the second angle can be called the foot blowing mode (as shown in FIG. Fig.10 shown).

[0068] In order to realize the function that the first rib plate structure 33 and the second rib plate structure 34 cooperate with the cavity wall of the accommodating cavity 14 respectively, the rotary damper 3 can separate the opening of the air guide groove 323 from each air outlet when rotating to different angles, or connect another part of the opening area of ​​the air guide groove 323 to the first air outlet 101 or the second air outlet 102 separately, in some embodiments, such as Figures 8 to 12 As shown, the housing 13 also has an air inlet 106, which is connected to the accommodating chamber 14. The accommodating chamber 14 is sequentially arranged with a first cavity wall 21, a second cavity wall 22, and a third cavity wall 23 in the circumferential direction of the rotary damper 3. The interval between the first cavity wall 21 and the second cavity wall 22 forms the aforementioned first air outlet 101, the interval between the second cavity wall 22 and the third cavity wall 23 forms the aforementioned second air outlet 102, and the interval between the first cavity wall 21 and the third cavity wall 23 forms the aforementioned air inlet 106.

[0069] Among them, Figure 8 As shown, when the rotary damper 3 rotates to the first A angle, the first rib plate structure 33 slides with the second cavity wall 22, and the second rib plate structure 34 slides with the third cavity wall 23, the second air outlet 102 is opposite to the closed area 31, and the first air outlet 101 and the air inlet 106 are opposite to the opening of the air guide groove 323. At this time, the first air outlet 101 and the air inlet 106 are both open relative to the air guide groove 323, so that the air supply structure can introduce the air into the air guide groove 323 through the air inlet 106, and then the air in the air guide groove 323 is discharged from the first air outlet 101. At this time, the second air outlet 102 is closed relative to the air guide groove 323, so that the air in the air guide groove 323 cannot be discharged from the second air outlet 102.

[0070] like Fig.12 As shown, when the rotary damper 3 rotates to the first B angle, the first rib plate structure 33 slides with the first cavity wall 21, and the second rib plate structure 34 slides with the second cavity wall 22, the first air outlet 101 is opposite to the closed area 31, and the second air outlet 102 and the air inlet 106 are opposite to the opening of the air guide groove 323. At this time, the second air outlet 102 and the air inlet 106 are both open relative to the air guide groove 323, so that the air supply structure can introduce the air into the air guide groove 323 through the air inlet 106, and then the air in the air guide groove 323 is discharged from the second air outlet 102. At this time, the first air outlet 101 is closed relative to the air guide groove 323, so that the air in the air guide groove 323 cannot be discharged from the first air outlet 101.

[0071] like Fig.10As shown, when the rotary damper 3 rotates to the second angle, the first rib plate structure 33 slides with the first cavity wall 21, and the second rib plate structure 34 slides with the third cavity wall 23, the first air outlet 101 and the second air outlet 102 are both opposite to the closed area 31, and the air inlet 106 is opposite to the opening of the air guide groove 323. At this time, the first air outlet 101 and the second air outlet 102 are both closed relative to the air guide groove 323, so that the wind in the air guide groove 323 cannot be discharged from the first air outlet 101 and the second air outlet 102, so that the wind in the air guide groove 323 can be drawn out from the vent 320 alone for discharge.

[0072] In order to realize the function of the first rib structure 33, in some embodiments, as Figure 4 As shown, the first rib structure 33 may include a first main rib 311, which extends outwardly in the radial direction of the rotary damper 3. The first main rib 311 may be fixed to the rotary damper 3, for example, integrally formed on the rotary damper 3. Figure 8 As shown, when the rotary damper 3 rotates to the first angle A, the first rib structure 33 slides with the second cavity wall 22 through the end of the first main rib 311 away from the center of the rotary damper 3; Fig.10 and Fig.12 As shown, when the rotary damper 3 rotates to the first angle B or the second angle, the first rib structure 33 slides with the first cavity wall 21 through the end of the first main rib 311 away from the center of the rotary damper 3.

[0073] In the above example, since the surface area of ​​the end of the first main rib 311 that is away from the center of the rotary damper 3 is smaller, when the end of the first main rib 311 that is away from the center of the rotary damper 3 slides with the first cavity wall 21 or the second cavity wall 22, the friction resistance can be reduced, which is beneficial to improving the smoothness of the rotation of the rotary damper 3.

[0074] In some embodiments, Figure 5 As shown, the end of the first main rib plate 311 away from the center of the rotary damper 3 may be provided with a first curved plate, the center of which coincides with the axis of the rotary damper 3 and is located in the closed area 31 on the outer periphery of the rotary damper 3. The first curved plate may be integrally formed on the first main rib plate 311. When the rotary damper 3 rotates to the first A angle, the first rib plate structure 33 slides with the second cavity wall 22 through the outer curved surface of the first curved plate; and when the rotary damper 3 rotates to the first B angle or the second angle, the first rib plate structure 33 slides with the first cavity wall 21 through the outer curved surface of the first curved plate.

[0075] In the above example, by arranging the first arc plate to slide with the first cavity wall 21 or the second cavity wall 22, the sealing performance between the rotary damper 3 and each cavity wall can be improved and air leakage can be reduced.

[0076] In order to realize the function of the second rib structure 34, in some embodiments, as Figure 4 As shown, the aforementioned second rib structure 34 may include a second main rib 312, the second main rib 312 extending outwardly along the radial direction of the rotary damper 3, and the second main rib 312 may be fixed on the rotary damper 3, for example, integrally formed on the rotary damper 3. Figure 8 and Fig.10 As shown, when the rotary damper 3 rotates to the first angle A or the second angle, the second rib structure 34 slides with the third cavity wall 23 through the end of the second main rib 312 away from the center of the rotary damper 3; Fig.12 As shown, when the rotary damper 3 rotates to the first angle B, the second rib structure 34 slides with the second cavity wall 22 through the end of the second main rib 312 away from the center of the rotary damper 3 .

[0077] In the above example, since the surface area of ​​the end of the second main rib 312 that is away from the center of the rotary damper 3 is smaller, when the end of the second main rib 312 that is away from the center of the rotary damper 3 slides with the second cavity wall 22 or the third cavity wall 23, the friction resistance can be reduced, which is beneficial to improving the smoothness of the rotation of the rotary damper 3.

[0078] In some embodiments, Figure 5 As shown, the end of the second main rib plate 312 away from the center of the rotary damper 3 may be provided with a second arc plate, the center of which coincides with the axis of the rotary damper 3 and is located in the closed area 31 on the outer periphery of the rotary damper 3. The second arc plate may be integrally formed on the second main rib plate 312. When the rotary damper 3 rotates to the first A angle or the second angle, the second rib plate structure 34 slides with the third cavity wall 23 through the outer arc surface of the second arc plate; and when the rotary damper 3 rotates to the first B angle, the second rib plate structure 34 slides with the second cavity wall 22 through the outer arc surface of the second arc plate.

[0079] In the above example, by arranging the second arc plate to slide with the second cavity wall 22 or the third cavity wall 23, the sealing performance between the rotary damper 3 and each cavity wall can be improved and air leakage can be reduced.

[0080] It should be noted here that: in some embodiments, both the first main rib 311 and the second main rib 312 extend radially outward from the center of the rotary damper 3, and the first main rib 311 and the second main rib 312 divide the circumference of the rotary damper 3 into the aforementioned wind guide area 32 and closed area 31.

[0081] In order to enable the rotary damper 3 to independently guide the wind when rotating to the first angle or the second angle, in some embodiments, as Figure 7As shown, the aforementioned accommodating cavity 14 has a fourth cavity wall opposite to the axial direction of the rotary damper 3, and the fourth cavity wall is provided with a first opening area and a first closed area 104. The first opening area forms a third air outlet 103. When the air supply structure of the utility model is applied to an automobile air conditioner, the third air outlet 103 can be a foot-blowing air outlet.

[0082] Among them, Fig.10 As shown, when the rotary damper 3 rotates to the aforementioned second angle, the vent 320 is opposite to the third air outlet 103, so that the vent 320 is connected to the third air outlet 103. At this time, the air outlet structure can lead the air from the vent 320 and discharge it through the third air outlet 103. Figure 8 and Fig.12 As shown, when the rotary damper 3 rotates to the first angle, the vent 320 is opposite to the first closed area 104, so that the vent 320 is closed by the first closed area 104. At this time, the air outlet structure cannot lead the wind out of the vent 320, which is conducive to leading the wind out from another part of the opening area of ​​the air guide groove 323 alone.

[0083] It should be noted here that when the coordinated structure of the third air outlet 103, the first closed area 104 and the vent 320 mentioned above is used in conjunction with the aforementioned first rib plate structure 33 and the second rib plate structure 34, the rotary damper 3 can guide the introduced wind out from another part of the opening area of ​​the air guide groove 323 when it is rotated to a first angle, and guide the introduced wind out from the vent 320 alone when it is rotated to a second angle.

[0084] In some embodiments, Figure 3 As shown, the projection of the aforementioned vent 320 in the axial direction of the rotary damper 3 can be located in the aforementioned wind guide area 32, so that the vent 320 can be directly processed on the fourth cavity wall along the axial direction of the rotary damper 3, thereby facilitating the processing of the vent 320. The opening size of the aforementioned vent 320 is approximately equal to or slightly smaller than the opening size of the third air outlet 103.

[0085] In some embodiments, Fig. 9 and Fig.11 As shown, the aforementioned rotating air door 3 can simultaneously guide the introduced wind from another part of the opening area of ​​the air guide groove 323 and the vent 320 when it is rotated to the third angle, so that the air supply mode of the air supply structure can be increased to meet different usage requirements.

[0086] In some embodiments, when the aforementioned housing 13 has a receiving cavity 14, the rotary damper 3 is located in the receiving cavity 14, and the rotary damper 3 is circumferentially spaced with a first rib structure 33 and a second rib structure 34, and the housing 13 further has a first air outlet 101 and a second air outlet 102 both connected to the receiving cavity 14, the third angle may include a third A angle and a third B angle. Fig. 9 As shown, the aforementioned first rib plate structure 33 and the second rib plate structure 34 respectively cooperate with the cavity wall of the accommodating cavity 14, so that when the rotary damper 3 rotates to the third angle A, another part of the opening area of ​​the air guide groove 323 is separately connected with the first air outlet 101, and the vent 320 is opposite to at least a part of the third air outlet 103. At this time, the vent 320 is connected with the third air outlet 103, and the air supply structure can lead part of the wind in the air guide groove 323 out from the first air outlet 101, and the other part out from the third air outlet 103.

[0087] like Fig.11 As shown, the aforementioned first rib plate structure 33 and the second rib plate structure 34 respectively cooperate with the cavity wall of the accommodating cavity 14, and also make another part of the opening area of ​​the air guide groove 323 connected with the second air outlet 102 separately when the rotary damper 3 rotates to the third angle B, and make the vent 320 opposite to at least a part of the third air outlet 103. At this time, the vent 320 is connected with the third air outlet 103, and the air supply structure can lead part of the wind in the air guide groove 323 out from the second air outlet 102, and the other part out from the third air outlet 103.

[0088] It should be noted here that: when the above-mentioned air supply structure is applied to a car air conditioner, and the first air outlet 101 is a face-blowing air outlet, the second air outlet 102 is a glass-blowing air outlet, and the third air outlet 103 is a foot-blowing air outlet, the mode of the above-mentioned air supply structure when the rotary damper 3 rotates to the third A angle can be called a face-blowing plus foot-blowing mode, and the mode of the air supply structure when the rotary damper 3 rotates to the third B angle can be called a glass-blowing plus foot-blowing mode.

[0089] In order to realize the function that the first rib plate structure 33 and the second rib plate structure 34 cooperate with the cavity wall of the accommodating cavity 14 respectively, so that the rotary damper 3 can discharge air from different air outlets at the same time when the rotary damper 3 rotates, in some embodiments, when the housing 13 also has an air inlet 106 connected to the accommodating cavity 14, and the accommodating cavity 14 is sequentially arranged with the first cavity wall 21, the second cavity wall 22 and the third cavity wall 23 in the circumferential direction of the rotary damper 3, and the interval between the first cavity wall 21 and the second cavity wall 22 forms the aforementioned first air outlet 101, the interval between the second cavity wall 22 and the third cavity wall 23 forms the aforementioned second air outlet 102, and the interval between the first cavity wall 21 and the third cavity wall 23 forms the aforementioned air inlet 106,

[0090] like Fig. 9 As shown, when the rotary damper 3 rotates to the third angle A, the first rib plate structure 33 slides with the second cavity wall 22, and the second rib plate structure 34 slides with the third cavity wall 23, the second air outlet 102 is opposite to the closed area 31, and the first air outlet 101 and the air inlet 106 are opposite to the opening of the air guide groove 323. At this time, the first air outlet 101 and the air inlet 106 are both open relative to the air guide groove 323, so that the air supply structure can introduce air into the air guide groove 323 through the air inlet 106, and then a part of the air in the air guide groove 323 is discharged from the first air outlet 101. At this time, the second air outlet 102 is closed relative to the air guide groove 323, so that the air in the air guide groove 323 cannot be discharged from the second air outlet 102. At this time, the vent 320 is opposite to at least a portion of the third air outlet 103 , so that the vent 320 is connected to the third air outlet 103 , so that a portion of the air in the air guide slot 323 is guided out from the third air outlet 103 .

[0091] like Fig.11 As shown, when the rotary damper 3 rotates to the third B angle, the first rib plate structure 33 slides with the first cavity wall 21, and the second rib plate structure 34 slides with the second cavity wall 22, the first air outlet 101 is opposite to the closed area 31, and the second air outlet 102 and the air inlet 106 are opposite to the opening of the air guide groove 323. At this time, the second air outlet 102 and the air inlet 106 are both open relative to the air guide groove 323, so that the air supply structure can introduce the wind into the air guide groove 323 through the air inlet 106, and then the wind in the air guide groove 323 is discharged from the second air outlet 102. At this time, the first air outlet 101 is closed relative to the air guide groove 323, so that the wind in the air guide groove 323 cannot be discharged from the first air outlet 101. At this time, the vent 320 is opposite to at least a part of the third air outlet 103, so that the vent 320 is connected with the third air outlet 103, so that a part of the wind in the air guide groove 323 is led out from the third air outlet 103.

[0092] In order to realize the function of the first rib structure 33, the first rib structure 33 can slide with the second cavity wall 22 when the rotary damper 3 rotates to the third angle A, and can slide with the first cavity wall 21 when the rotary damper 3 rotates to the third angle B. Figure 4 As shown, when the aforementioned first rib plate structure 33 includes the first main rib plate 311, the first rib plate structure 33 also includes a first auxiliary rib plate 313, and the first auxiliary rib plate 313 is located in the closed area 31. The first auxiliary rib plate 313 can be arranged in the middle of the first main rib plate 311, or can be arranged at the end of the first main rib plate 311, and the two cases are described one by one below.

[0093] In one example, if Figure 4As shown, the first auxiliary rib plate 313 is disposed in the middle of the first main rib plate 311. Specifically, one end of the first auxiliary rib plate 313 is connected to the middle of the first main rib plate 311, and the other end is a free end. The first auxiliary rib plate 313 can be fixed, for example, integrally formed on the first main rib plate 311. Fig. 9 As shown, when the rotary damper 3 rotates to the third angle A, the first rib structure 33 slides with the second cavity wall 22 through the free end of the first rib plate 313; Fig.11 As shown, when the rotary damper 3 rotates to the third angle B, the first rib structure 33 slides with the first cavity wall 21 through the free end of the first auxiliary rib 313 and / or the end of the first main rib 311 away from the center of the rotary damper 3.

[0094] In the above example, since the surface areas of the free end of the first attached rib plate 313 and the end of the first main rib plate 311 away from the center of the rotary damper 3 are both small, when the free end of the first attached rib plate 313 or the end of the first main rib plate 311 away from the center of the rotary damper 3 slides with the first cavity wall 21 or the second cavity wall 22, the friction resistance can be reduced, which is beneficial to improving the smoothness of the rotation of the rotary damper 3.

[0095] In another example, if Figure 5 As shown, the first attached rib plate 313 is arranged at the end of the first main rib plate 311. Specifically, the aforementioned first attached rib plate 313 can be a first arc-shaped plate, the center of the first arc-shaped plate coincides with the axis of the rotary damper 3, one end of the first attached rib plate 313 is connected to the end of the first main rib plate 311 away from the center of the rotary damper 3, and the first attached rib plate 313 can form an integral structure with the first main rib plate 311. When the rotary damper 3 rotates to the first A angle or the third A angle, the first rib plate structure 33 is slidably matched with the second cavity wall 22 through the outer arc surface of the first attached rib plate 313; and when the rotary damper 3 rotates to the first B angle, the third B angle or the second angle, the first rib plate structure 33 is slidably matched with the first cavity wall 21 through the outer arc surface of the first attached rib plate 313.

[0096] In the above example, by providing the first rib plate 313 as an arc-shaped plate to slide with each cavity wall, the sealing performance between the rotary damper 3 and each cavity wall can be improved and air leakage can be reduced.

[0097] In order to realize the function of the second rib structure 34, the first rib structure 33 can slide with the third cavity wall 23 when the rotary damper 3 rotates to the third angle A, and can slide with the second cavity wall 22 when the rotary damper 3 rotates to the third angle B. Figure 4As shown, when the second rib plate structure 34 includes the second main rib plate 312, the second rib plate structure 34 also includes a second auxiliary rib plate 314, and the second auxiliary rib plate 314 is located in the closed area 31. The second auxiliary rib plate 314 can be arranged in the middle of the second main rib plate 312, or can be arranged at the end of the second main rib plate 312, and the two cases are described one by one below.

[0098] In one example, if Figure 4 As shown, the second auxiliary rib plate 314 is disposed in the middle of the second main rib plate 312. Specifically, one end of the second auxiliary rib plate 314 can be connected to the middle of the second main rib plate 312, and the other end is a free end. The second auxiliary rib plate 314 can be fixed, for example, integrally formed on the second main rib plate 312. Fig. 9 As shown, when the rotary damper 3 rotates to the third angle A, the second rib structure 34 slides with the third cavity wall 23 through the free end of the second auxiliary rib 314 and / or the end of the second main rib 312 away from the center of the rotary damper 3; Fig.11 As shown, when the rotary damper 3 rotates to the third angle B, the second rib structure 34 slidably cooperates with the second cavity wall 22 through the free end of the second attached rib 314 .

[0099] In the above example, since the surface areas of the free end of the second attached rib plate 314 and the end of the second main rib plate 312 away from the center of the rotary damper 3 are both small, when the free end of the second attached rib plate 314 or the end of the second main rib plate 312 away from the center of the rotary damper 3 slides with the second cavity wall 22 or the third cavity wall 23, the friction resistance can be reduced, which is beneficial to improving the smoothness of the rotation of the rotary damper 3.

[0100] In another example, if Figure 5 As shown, the second rib plate 314 is arranged at the end of the second main rib plate 312. Specifically, the second rib plate 314 can be a second arc-shaped plate, the center of the second arc-shaped plate coincides with the axis of the rotary damper 3, one end of the second rib plate 314 is connected to the end of the second main rib plate 312 away from the center of the rotary damper 3, and the second rib plate 314 can form an integral structure with the second main rib plate 312. When the rotary damper 3 rotates to the first A angle, the third A angle or the second angle, the first rib plate structure 33 is slidably matched with the third cavity wall 23 through the outer arc surface of the second rib plate 314; and when the rotary damper 3 rotates to the first B angle or the third B angle, the first rib plate structure 33 is slidably matched with the second cavity wall 22 through the outer arc surface of the first rib plate 313.

[0101] In the above example, by providing the second rib plate 314 as an arc-shaped plate to slide with each cavity wall, the sealing performance between the rotary damper 3 and each cavity wall can be improved and air leakage can be reduced.

[0102] It should be noted that: in one embodiment, Figure 4 As shown, when the first attached rib plate 313 is disposed in the middle of the first main rib plate 311, and the second attached rib plate 314 is disposed in the middle of the second main rib plate 312, the first arc formed by the first main rib plate 311 and the first attached rib plate 313 on the arc of the rotary damper 3 is approximately half of the arc of the first air outlet 101 or the second air outlet 102 on the rotary damper 3. The second arc formed by the second main rib plate 312 and the second attached rib plate 314 on the arc of the rotary damper 3 is approximately equal to the first arc.

[0103] The embodiment of the utility model further provides an air conditioning device, which may include any of the above-mentioned air supply structures. Among them, because the air conditioning device adopts the above-mentioned air supply structure, compared with the solution in the prior art that all ventilation openings are arranged in the circumferential direction of the rotary damper 3, the technical solution of the utility model can utilize the space in the circumferential direction and axial direction of the rotary damper 3 by distributing the ventilation openings 320 in both the circumferential direction and the axial direction of the rotary damper 3, avoiding the problem of a large local volume of the air supply structure caused by only utilizing the space in the circumferential direction of the rotary damper 3, so that the overall structure of the air supply structure can be distributed more evenly and compactly.

[0104] It should be noted here that the above-mentioned air-conditioning device may be an automobile air-conditioning device.

[0105] In some embodiments, Figure 2 and Figure 6 As shown, the air conditioning device comprises a volute 1, a heat exchanger 8 and a heater 7. The volute 1 comprises an air outlet duct 105, and the heat exchanger 8 and the heater 7 are both arranged in the air outlet duct 105. In the air outlet direction along the air outlet duct 105, the heater 7 is located at the downstream side of the heat exchanger 8. The air outlet duct 105 discharges air through the air supply structure, and the housing 13 of the air supply structure is integrally formed on the volute 1.

[0106] In the above example, the overall structure of the air conditioner can be made more compact by integrally forming the housing 13 of the air supply structure on the volute 1. In the air outlet direction of the air outlet duct 105, the aforementioned rotary damper 3 is located on the downstream side of the heater 7, and the air outlet duct 105 blows the wind into the air guide slot 323 of the rotary damper 3, and the rotary damper 3 rotates to different angles to guide the wind of the air outlet duct 105 out from the corresponding air outlet.

[0107] It should be noted here that the above-mentioned heater 7 can be a PTC heater.

[0108] like Figure 2As shown, the volute 1 may be a two-half structure, which is a first volute 11 and a second volute 12. The air conditioning device also includes a fan assembly 2, a damper actuator 5, a first joint 4 and a second joint 9. The volute 1 may have a return air port 10.

[0109] The fan assembly 2 is used to assist the air conditioning device in taking in and out air. The damper actuator 5 is used to drive the rotary damper 3 to rotate. The damper actuator 5 may include a damper motor to drive the rotary damper 3 to rotate through the damper motor. The damper motor may be a stepping motor or the like. The number of the aforementioned third air outlets 103 may be two, one third air outlet 103 is connected to the first joint 4 to discharge air through the first joint 4. The other third air outlet 103 is connected to the second joint 9 to discharge air through the second joint 9.

[0110] like Figure 6 As shown, the aforementioned first air outlet 101 and the second air outlet 102 are respectively arranged downstream of the rotary damper 3 along the air outlet direction of the air outlet duct 105; the third air outlet 103 is located on both sides or near both sides of the volute 1. In terms of spatial layout, the first air outlet 101 and the second air outlet 102 are arranged in the circumferential direction downstream of the rotary damper 3. The third air outlet 103 is arranged on both sides of the volute 1, and is arranged in the axial direction of the rotary damper 3.

[0111] For ease of understanding, the air conditioning device is taken as an automobile air conditioning device, and the first air outlet 101 is a face-blowing air outlet, the second air outlet 102 is a glass-blowing air outlet, and the third air outlet 103 is a foot-blowing air outlet. The glass-blowing air outlet may also be referred to as a defrosting air outlet.

[0112] The utility model achieves the purpose of miniaturization and compactness of the air conditioning box assembly (HVAC) by simply connecting the heat exchanger 8 and the heater 7 (which can be a PTC heater) in series on the air outlet duct 105, and by designing the face-blowing air outlet, the foot-blowing air outlet and the glass-blowing air outlet in a compact structure. The face-blowing air outlet, the foot-blowing air outlet and the glass-blowing air outlet are controlled by the same rotary damper 3. By simplifying the damper control and transmission mechanism design, the rotary damper 3 is driven by the damper motor to rotate, and the driving connecting rod, rocker arm, turntable and other parts commonly used between the damper motor and the damper in traditional HVAC are eliminated, thereby reducing the number of mechanism parts and saving costs; by simplifying the damper control logic, the air outlet requirements of different air outlets are achieved by simple rotational motion, and the five air supply modes of HVAC are realized, thereby improving the reliability of the mechanism. Compared with the traditional HVAC assembly, the utility model requires a small space structure while meeting the requirements of cooling, heating and realizing five air supply modes, thereby reducing the space occupied by the car, reducing weight and saving costs.

[0113] The fan assembly 2 sends the sucked air through the heat exchanger 8, the heater 7 and the rotary damper 3 through high-speed rotation, and the damper actuator 5 drives the rotary damper 3 to rotate. Figures 8 to 12 As shown, the rotary damper 3 rotates to different angles, the first air outlet 101 or the second air outlet 102 partially or completely overlaps with the wind guide area 32 or the closed area 31 of the rotary damper 3, respectively, and the third air outlet 103 is partially or completely blocked by the first baffle 321 or the second baffle 322. Through the combination of the above-mentioned matching conditions, five air supply modes are realized, namely: face blowing mode, face blowing plus foot blowing mode, foot blowing mode, glass blowing plus foot blowing mode and glass blowing mode. The following is a description of the five modes respectively.

[0114] 1. Blowing mode: Figure 8 As shown, the first main rib plate 311 is between the first air outlet 101 (i.e., the face-blowing air outlet) and the second air outlet 102 (i.e., the glass-blowing air outlet), and the first main rib plate 311 slides with the second cavity wall 22 to isolate the first air outlet 101 from the second air outlet 102. The second main rib plate 312 and the second auxiliary rib plate 314 slide with the third cavity wall 23. At this time, the first air outlet 101 completely corresponds to the wind guide area 32 of the rotary damper 3, and the second air outlet 102 completely corresponds to the closed area 31 of the rotary damper 3. At this time, the first auxiliary rib plate 313 corresponds to the range of the second air outlet 102 and does not work. The vent 320 is now closed by the first closed area 104 on the fourth cavity wall, so the vent 320 does not work, so that the third air outlet 103 (i.e., the foot-blowing air outlet) is in a closed state.

[0115] The air guide area 32 is connected to the aforementioned air inlet 106, and the air supply structure is connected to the air outlet duct 105 through the air inlet 106. At this time, only the first air outlet 101 is fully opened to achieve the function of blowing cold and warm air on the face.

[0116] 2. Face and foot blowing mode: Fig. 9 As shown, the first main rib plate 311 corresponds to the middle of the first air outlet 101 (i.e., the face-blowing air outlet), and the first auxiliary rib plate 313 is between the first air outlet 101 and the second air outlet 102 (i.e., the glass-blowing air outlet), and plays the role of isolating the first air outlet 101 and the second air outlet 102. The first auxiliary rib plate 313 is slidably matched with the second cavity wall 22, and the second main rib plate 312 and the second auxiliary rib plate 314 are both slidably matched with the third cavity wall 23. At this time, the second air outlet 102 completely corresponds to the closed area 31 of the rotary damper 3. The first baffle plate 321 or the second baffle plate 322 blocks half of the third air outlet 103 (i.e., the foot-blowing air outlet), so that the vent 320 is connected to half of the third air outlet 103. Therefore, the third air outlet 103 is in a semi-wind-conducting state, and part of the circulating airflow is blown out from the third air outlet 103.

[0117] Among them, the rotary damper 3 rotates a certain angle based on the position of the face-blowing mode, and the closed area 31 of the rotary damper 3 partially blocks the first air outlet 101, but a part of the first air outlet 101 is still connected to the air inlet 106 through the air guide area 32, and is connected to the air outlet duct 105 through the air inlet 106, so that air can still be blown out of the first air outlet 101. The third air outlet 103 is connected to an air outlet connector (i.e., the aforementioned first connector 4 or second connector 9). At this time, the first air outlet 101 is kept half-open and the third air outlet 103 is kept half-open, realizing the functions of blowing cold and warm air on the face and blowing on the feet.

[0118] 3. Foot blowing mode: Fig.10 As shown, the first main rib plate 311 is slidably matched with the first cavity wall 21, and the second main rib plate 312 is slidably matched with the third cavity wall 23. The first main rib plate 311 and the second main rib plate 312 cooperate to separate the air inlet 106 from the first air outlet 101 (i.e., the face-blowing air outlet) and the second air outlet 102 (i.e., the glass-blowing air outlet). At this time, the first air outlet 101 and the second air outlet 102 are completely corresponding to the closed area 31 of the rotary damper 3. At this time, the vent 320 is completely opposite to the third air outlet 103 (i.e., the foot-blowing air outlet), so the third air outlet 103 is in a completely air-guiding state, and the circulating airflow is only blown out from the third air outlet 103.

[0119] Among them, the rotary air door 3 rotates a certain angle based on the face-blowing and foot-blowing mode positions. At this time, the first air outlet 101 and the second air outlet 102 are closed, and only the third air outlet 103 is fully opened to achieve the function of blowing cold or warm air to the feet.

[0120] 4. Foot blowing and glass blowing mode: Fig.11 As shown, the first main rib plate 311 corresponds to the middle of the third air outlet 103 (i.e., the foot-blowing air outlet), and the first auxiliary rib plate 313 is slidably matched with the first cavity wall 21. The second main rib plate 312 corresponds to the middle of the second air outlet 102 (i.e., the glass-blowing air outlet), and the second auxiliary rib plate 314 corresponds to between the first air outlet 101 (i.e., the face-blowing air outlet) and the second air outlet 102, playing the role of isolating the first air outlet 101 and the second air outlet 102. At this time, the closed area 31 corresponds to half of the second air outlet 102 and the entire first air outlet 101. The first baffle 321 or the second baffle 322 blocks half of the third air outlet 103, so that the vent 320 is connected to half of the third air outlet 103. At this time, the first air outlet 101 is completely closed, and the second air outlet 102 and the third air outlet 103 are in a semi-wind-conducting state.

[0121] A partial area of ​​the vent 320 corresponds to the third air outlet 103 , so the third air outlet 103 is in a semi-wind-conducting state, and part of the circulating airflow is blown out from the third air outlet 103 .

[0122] The rotary damper 3 rotates a certain angle based on the position of the foot blowing mode, at which time the closed area 31 of the rotary damper 3 has partially left the second air outlet 102, and part of the wind guide area 32 overlaps with the second air outlet 102. The second air outlet 102 is connected to the air induction port 106 through the wind guide area 32 of the rotary damper 3, and is connected to the air outlet duct 105 through the air induction port 106. Some wind blows out from the second air outlet 102; the closed area 31 of the rotary damper 3 has completely blocked the first air outlet 101, and the first air outlet 101 is closed; at this time, the first air outlet 101 is closed, and the second air outlet 102 and the third air outlet 103 are kept half open, so as to realize the functions of foot blowing and glass blowing with cold and warm air.

[0123] 5. Glass blowing mode: Fig.12 As shown, the first main rib 311 is slidably matched with the first cavity wall 21, and the first baffle 321 or the second baffle 322 blocks the third air outlet 103 (i.e., the foot-blowing air outlet), which plays a role in isolating the third air outlet 103. The second main rib 312 corresponds to the middle of the first air outlet 101 (i.e., the face-blowing air outlet) and the second air outlet 102 (i.e., the glass-blowing air outlet), which plays a role in isolating the first air outlet 101 and the second air outlet. At this time, the first air outlet 101 completely corresponds to the closed area 31 of the rotary damper 3. The vent 320 is now closed by the first closed area 104, so the vent 320 does not work, so that the third air outlet 103 is in a closed state.

[0124] The rotary damper 3 rotates a certain angle based on the position of the foot blowing and glass blowing mode. At this time, the closed area 31 of the rotary damper 3 has completely left the second air outlet 102. The second air outlet 102 is connected to the air inlet 106 through the air guide area 32 of the rotary damper 3, and is connected to the air outlet duct 105 through the air inlet 106. The wind blows out from the second air outlet 102; the closed area 31 of the rotary damper 3 still completely blocks the first air outlet 101, and the first air outlet 101 is closed; the first baffle 321 or the second baffle 322 blocks the third air outlet 103, so that the third air outlet 103 is closed. At this time, the first air outlet 101 and the third air outlet 103 are closed, and the second air outlet 102 is kept fully open, so as to realize the function of blowing glass with cold and warm air.
