[0070] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the embodiments of this application are intended to cover non-exclusive inclusion.
[0072] Please refer to Figures 1 - 22 , a housing of an air conditioner is provided in the embodiments of this application. The housing 10 includes an outer housing 100 and an inner housing 200.
[0073] Among them, please refer to Figures 2 - 5 , the air conditioner includes an indoor air duct assembly 20 and an outdoor air duct assembly 30. The indoor air duct assembly 20 is used for heat exchange between the medium and indoor air; the outdoor air duct assembly 30 is used for heat exchange between the medium and outdoor air, so as to realize heat exchange between indoor air and outdoor air.
[0074] The indoor air duct assembly 20 is a cross-flow air duct assembly or a centrifugal air duct assembly. Figures 2 - 18 For an air conditioner using a cross-flow air duct assembly, the cross-flow air duct assembly includes an air impeller 201. The air impeller is a cross-flow air impeller 201. When the air impeller 201 rotates, air flows into the blade row from the open part of the air impeller 201, passes through the inside of the air impeller, and flows out from the blade row on the other side of the air impeller 201. Figures 19 - 22 For an air conditioner using a centrifugal air duct assembly, the centrifugal air duct assembly includes an air impeller 201. The air impeller 201 is a centrifugal air impeller. Air enters from the center of the air impeller 201 and is radially thrown out under the action of centrifugal force, and is collected and guided to the outlet by a centrifugal volute.
[0075] Please refer to Figure 1 , the outer housing 100 is used to provide an installation reference for the inner housing 200, the indoor air duct assembly 20, and the outdoor air duct assembly 30. When the air conditioner is installed on a vehicle, the outer housing 100 is fixedly connected to the vehicle.
[0076] The housing 100 has an installation cavity, which includes a first area and a second area. The housing 100 is provided with an indoor air inlet 100a and an indoor air outlet 100b that communicate with the first area, and the housing 100 is also provided with an outdoor air inlet 100c and an outdoor air outlet 100d that communicate with the second area. It can be understood that the indoor air inlet 100a is used for indoor air to flow into the installation cavity, and the indoor air outlet 100b is used for indoor air to flow out of the installation cavity. The outdoor air inlet 100c is used for outdoor air to flow into the installation cavity, and the outdoor air outlet 100d is used for outdoor air to flow out of the installation cavity.
[0077] The inner housing 200 is integrally formed with the outer housing 100 separately, and the inner housing 200 is located in the first area and connected to the outer housing 100. That is to say, the inner housing 200 is arranged inside the outer housing 100. The inner housing 200 and the outer housing 100 are not integrally formed, but are formed and connected separately.
[0078] The inner housing 200 has an inner cavity, which is used to accommodate a cross-flow air duct assembly or a centrifugal air duct assembly. That is to say, the inner cavity of the inner housing 200 can accommodate a cross-flow air duct assembly or a centrifugal air duct assembly.
[0079] Please refer to Figures 2 - 5 , the inner housing 200 has a first air inlet 200a communicating with the indoor air inlet 100a and a first air outlet 200b communicating with the indoor air outlet 100b. It can be understood that indoor air can enter the indoor air duct assembly 20 from the indoor air inlet 100a and the first air inlet 200a, and the air discharged from the indoor air duct assembly 20 can be discharged into the room through the first air outlet 200b and the indoor air outlet 100b. The outdoor air duct assembly 30 is arranged in the second area. Outdoor air can flow into the outdoor air duct assembly 30 from the outdoor air inlet 100c, and the air flowing out of the outdoor air duct assembly 30 can flow out to the outside through the outdoor air outlet 100d.
[0080] In the above embodiment, the housing 10 includes a separately formed outer housing 100 and an inner housing 200, where the inner housing 200 is located in the first area of the outer housing 100, and the inner housing 200 is used to accommodate a cross-flow air duct assembly or a centrifugal air duct assembly. When designing an air conditioner, by adjusting the inner housing 200 of the housing 10 to make the inner housing 200 adapt to the cross-flow air duct assembly or make the inner housing 200 adapt to the centrifugal air duct assembly, it is possible to adjust the cross-flow air duct assembly to a centrifugal air duct assembly or adjust the centrifugal air duct assembly to a cross-flow air duct assembly without replacing the outer housing 100, which reduces the design cost and the subsequent mold development cost.
[0081] It can be understood that the inner shell 200 and the outer shell 100 can be fixedly connected in a non-detachable manner. In some specific embodiments, the inner shell 200 is foam-molded on the outer shell 100. That is, the outer shell 100 is first molded, and then the inner shell 200 is foam-molded on the surface of the outer shell 100. The foam-molded inner shell 200 has good heat insulation performance, thus reducing heat loss.
[0082] The inner shell 200 and the outer shell 100 can be detachably connected. In some embodiments, the inner shell 200 and the outer shell 100 are connected by interference fit. That is to say, the outer shell 100 and the inner shell 200 are molded separately, and then assembled and connected by interference fit.
[0083] In some embodiments, the housing includes an air duct fixing cover 230. The air duct fixing cover 230 is disposed in the installation cavity and is located outside the inner shell 200. The air duct fixing cover 230 presses on the inner shell 200 and is firmly connected to the outer shell 100. The inner shell 200 is pressed by the air duct fixing cover 230 on the outer shell 100, thereby realizing the connection between the inner shell 200 and the outer shell 100. This connection method has relatively better connection reliability, is not easily loosened in a vibration environment, and is convenient for disassembly and repair operations.
[0084] Among them, the specific material of the inner shell 200 is not limited. In some embodiments, the material of the inner shell 200 is foam plastic. Foam plastic can be interference-fitted with the outer shell 100 through its own deformation and has good heat insulation performance.
[0085] The following will be combined with Figure 1 、 Figures 6 - 8 、 Figures 14 - 15 to describe the structure of the outer shell 100.
[0086] In some embodiments, the outer shell 100 includes a chassis 110 and a top cover 120. The chassis 110 and the top cover 120 enclose an installation cavity. During installation, the inner shell 200, the cross-flow air duct assembly or the centrifugal air duct assembly can be disposed on the chassis 110, and then the top cover 120 is covered on the chassis 110 to dispose the inner shell 200, the cross-flow air duct assembly or the centrifugal air duct assembly in the installation cavity.
[0087] The indoor air inlet 100a and the indoor air outlet 100b are disposed on the chassis 110. It should be noted that when the air conditioner is assembled to the vehicle, the chassis 110 is connected to the vehicle to facilitate the air inside the vehicle (i.e., inside the vehicle) to pass through the indoor air inlet 100a and the indoor air outlet 100b.
[0088] In some embodiments, please refer to Figures 6 - 8, the chassis 110 includes a disk body 111, a first support platform 112 protruding from the disk body 111, and a second support platform 113 protruding from the disk body 111. The first support platform 112 and the second support platform 113 are used to support the axial ends of the wind wheel 201. Here, the wind wheel 201 is the wind wheel 201 of the cross-flow air duct assembly or the wind wheel 201 of the centrifugal air duct assembly.
[0089] The first support platform 112 and the second support platform 113 are distributed on opposite sides of the inner shell 200. In this way, when setting the inner shell 200, it can be positioned through the first support platform 112 and the second support platform 113, thus facilitating the installation of the inner shell 200. In a specific embodiment, the first support platform 112 and the second support platform 113 are distributed on opposite sides of the indoor air outlet 100b.
[0090] The disk body 111, the first support platform 112, and the second support platform 113 are integrally formed. It can be understood that both the first support platform 112 and the second support platform 113 are integrally injection-molded with the disk body 111, and there is no assembly relationship. In actual production, there is no need to assemble these two support platform structures, which has high efficiency, good integrity, high strength, and excellent stability.
[0091] Furthermore, please refer to Figures 14 - 15 , the wind wheel 201 is a rotating component, one end of which is drivingly connected to the fan 202. Among the first support platform 112 and the second support platform 113, the second support platform 113 can be used to support the fan 202, and the first support platform 112 can be a bearing seat support platform. The other end of the wind wheel 201 is arranged on the first support platform 112 through a bearing seat 204. Among them, a bearing seat installation groove is provided at the top of the first support platform 112 to adapt to the above-mentioned bearing seat 204. A fan installation groove is provided at the top of the second support platform 113. In some embodiments, the fan 202 is installed on the second support platform 113 through a fan pressing plate 205, and screw positions for the fan pressing plate 205 are provided on the second support platform 113.
[0092] Part of the first support platform 112 is exposed, and it is easy to generate condensate.
[0093] In this regard, in some embodiments, please refer to Figures 6 - 8 , the side wall of the first support platform 112 facing the second support platform 113 includes an upper side wall 1121, a lower side wall 1122, and a step 1123 between the upper side wall 1121 and the lower side wall 1122. A water receiving groove 1123a is provided on the step 1123, and the water receiving groove 1123a is used to receive the condensate on the upper side wall 1121. Among them, the lower side wall 1122 can be in contact with the inner shell 200, and the upper side wall 1121 is in an exposed state and is easy to generate condensate. By providing the water receiving groove 1123a, the condensate on the upper side wall 1121 can be received, thus preventing the above-mentioned condensate from being blown out from the indoor air outlet 100b and causing a poor user experience.
[0094] The step 1123 is provided with a drain hole 1123b communicating with the water receiving tank 1123a, and the drain hole 1123b penetrates through the side wall of the first support platform 112. Among them, the drain hole 1123b at the step 1123 of the side wall of the support platform can be obtained and manufactured by the form of a through-hole formed by a mold. Through the drain port, the condensed water in the water receiving tank 1123a can be directly discharged to the outside of the air conditioner.
[0095] It can be understood that both the cross-flow air duct assembly and the centrifugal air duct assembly include the evaporator 203.
[0096] In order to install the evaporator 203, in some embodiments, please refer to Figures 6 - 7 , the chassis 110 includes a plurality of third support platforms 114 protruding from the disk body 111. The third support platforms 114 are used to support the evaporator 203, and the third support platforms 114 are integrally formed with the disk body 111.
[0097] Among them, the number of the third support platforms 114 is not limited. For example, two third support platforms 114 can be arranged in the area between the indoor air inlet 100a and the indoor air outlet 100b, and one third support platform 114 is respectively arranged at both ends of the indoor air inlet 100a along the axial direction of the air impeller 201.
[0098] By integrally forming the third support platform 114 with the disk body 111, there is no assembly relationship between the third support platform 114 and the disk body 111. In actual production, there is no need to assemble the structure of the third support platform 114, which has high efficiency, good integrity, high strength and excellent stability.
[0099] It can be understood that the first support platform 112, the second support platform 113 and the third support platform 114 are all structures protruding from the disk body 111 for the convenience of mold release. In some embodiments, the first support platform 112, the second support platform 113 and the third support platform 114 are reduced from one end connected to the disk body 111 to the other end to form a draft angle. That is to say, the first support platform 112, the second support platform 113 and the third support platform 114 all have a large bottom and a small top shape to facilitate mold release after injection molding, and the above structure can improve the connection strength with the disk body 111.
[0100] Among them, the second support platform 113 and the third support platform 114 are gradually reduced from one end connected to the disk body 111 to the other end. And the upper side wall 1121 and the lower side wall 1122 of the first support platform 112 are gradually reduced from the bottom to the other end.
[0101] In order to improve the strength of the chassis 110. Please refer to Figure 7In some embodiments, first reinforcing ribs 1141 are provided at the connection between the tray body 111 and the first support platform 112, at the connection between the tray body 111 and the second support platform 113, and at the connection between the tray body 111 and the third support platform 114. Second reinforcing ribs 1111 are provided at the connection between the side wall of the tray body 111 and the bottom wall of the tray body 111.
[0102] It should be noted that when assembling the inner shell 200, since the inner shell 200 is made of foam plastic, the processing tolerance is very large. If the tolerance of the inner shell 200 is too large, the assembly surface of the inner shell 200 and the outer shell 100 is directly in contact and difficult to compress, and the tolerance assembly cannot be performed, resulting in poor product tolerance assembly performance. By providing the first reinforcing rib 1141 and the second reinforcing rib 1111, the original surface contact can be changed to line contact, which is convenient for accommodating the processing and manufacturing tolerance of the inner shell 200. In subsequent production and manufacturing, even if the size of the inner shell 200 is too large, it can be strongly compressed and extruded through line contact with the ribs.
[0103] Combine the following Figure 2 , Figure 5 , Figures 9 - 13 , Figures 16 - 22 , the structure of the inner shell 200 is described.
[0104] For some embodiments, please refer to 2 and Figure 5 The inner shell 200 includes an air duct support 210 and an air duct cover 220, and the air duct support 210 and the air duct cover 220 surround an inner cavity. The air duct support 210 is assembled on the chassis 110, and the first air inlet 200a and the first air outlet 200b are arranged on the air duct support 210. A crossflow air duct assembly or a centrifugal air duct assembly can be arranged on the air duct support 210, and then the air duct cover 220 is covered on the air duct support 210 to accommodate the crossflow air duct assembly or the centrifugal air duct assembly in the inner cavity.
[0105] In order to make the air duct support 210 and the chassis 110 compatible for easy assembly. Figure 9 , Figure 11 and Figure 13 , the air duct support 210 is provided with a plurality of mounting openings 210a, wherein two mounting openings 210a are respectively located on both sides of the first air outlet 200b for the first support platform 112 and the second support platform 113 to extend out, and the remaining plurality of mounting openings 210a are used for the third support platform 114 to extend out. When the air duct support 210 is assembled, the two mounting openings 210a located on both sides of the first air outlet 200b can avoid the first support platform 112 and the second support platform 113, and the remaining plurality of mounting openings 210a can avoid the third support platform 114.
[0106] It should be added here that since the first support platform 112, the second support platform 113, and the third support platform 114 all have draft angles, when the air duct support 210 is pressed down and assembled onto the chassis 110, the air duct support 210 can be deformed by the above three support platforms, thereby improving the sealing performance of the connection with the above three support platforms.
[0107] Among them, the shape of the installation opening 210a is not limited. For example, two installation openings 210a on both sides of the first air outlet 200b can be located at the edge of the air duct support 210, and specifically, it is an open slot structure, while the remaining multiple installation openings 210a are located in the middle of the air duct support 210, and specifically, it is a through-hole structure.
[0108] In order to further reduce the costs of design and mold manufacturing. In some embodiments, the air duct cover 220 defines a first cavity; the inner cavity is used to accommodate the centrifugal air duct assembly, the air duct support 210 defines a second cavity, and the first cavity and the second cavity jointly define the inner cavity. Or the air duct cover 220 defines a first cavity, the inner cavity is used to accommodate the cross-flow air duct assembly, the air duct support 210 defines a third cavity, and the first cavity and the third cavity jointly define the inner cavity.
[0109] It can be understood that the air duct cover 220 can be adapted to the installation of the centrifugal air duct assembly and can also be adapted to the installation of the cross-flow air duct assembly. Therefore, only the structure of one air duct cover 220 needs to be designed, and a set of molds corresponding to the air duct cover 220 needs to be manufactured, thereby reducing the costs of design and mold manufacturing.
[0110] In addition, when the centrifugal air duct assembly uses an extra-large centrifugal impeller 201, a volute opening 220a needs to be provided on the air duct cover 220. Figure 22 The air duct support 210 shown is applicable to the extra-large centrifugal impeller 201.
[0111] In this regard, in some embodiments, the inner cavity is used to accommodate the centrifugal air duct assembly, the air duct cover 220 defines a first cavity, the air duct support 210 defines a second cavity, and the first cavity and the second cavity jointly define the inner cavity; or the inner cavity is used to accommodate the cross-flow air duct assembly, the air duct support 210 defines a third cavity, the air duct cover 220 defines a fourth cavity, and the third cavity and the fourth cavity jointly define the inner cavity. That is to say, two air duct covers 220 need to be provided to be respectively adapted to two air duct supports 210.
[0112] It should be noted that the air outlet structure of the centrifugal air duct assembly is not exactly the same as that of the cross-flow air duct assembly.
[0113] In this regard, in some embodiments, please refer to Figure 21, the inner cavity is used to accommodate the centrifugal air duct assembly. The air duct support 210 is assembled on the chassis 110. An air outlet adjustment plate 115 is provided at the indoor air outlet 100b. The air outlet adjustment plate 115 and the indoor air outlet 100b jointly define a second air outlet adapted to the centrifugal volute of the centrifugal air duct assembly. That is to say, the air outlet adjustment plate 115 can adjust the indoor air outlet 100b of the chassis 110 so as to adjust it into a second air outlet adapted to the centrifugal air duct assembly.
[0114] Specifically, the air outlet adjustment plate 115 includes a lapping portion located on the outside of itself and a matching portion located on the inside of itself. The lapping portion is lapped and connected to the edge of the indoor air outlet 100b, and the matching portion is inside the indoor air outlet 100b. The matching portion constitutes part or all of the side walls of the second air outlet.
[0115] It can be understood that both the cross-flow air duct assembly and the centrifugal air duct assembly have an evaporator 203. The evaporator 203 is located between the first air inlet 200a and the first air outlet 200b. The surface temperature of the evaporator 203 is low and it is easy to generate condensate.
[0116] In this regard, in some embodiments, please refer to Figures 4 - 5 , Figure 9 , a water receiving tray 211 is formed on the air duct support 210 between the first air inlet 200a and the first air outlet 200b. The water receiving tray 211 is used to receive the condensate of the evaporator 203.
[0117] Among them, the water receiving tray 211 has a sunken trough body. The side wall of the air duct support 210 directly constitutes part of the side wall of the trough body to reduce its structure and the forming difficulty. The water receiving tray 211 has a drain port. Two drain ports can be provided. The two drain ports are arranged at both ends of the water receiving tray 211 along the axial direction of the impeller 201. The drain ports are used to divert the water in the water receiving tray 211 to the outside.
[0118] Among them, please refer to Figures 11 - 12 , Figure 20 , an air duct volute tongue 212 is provided at the first air outlet 200b. As can be seen from Figure 12 and Figure 20 , the air duct volute tongue 212 cooperating with the cross-flow impeller 201 is formed on the air duct support 210. The air duct volute tongue 212 cooperating with the centrifugal impeller 201 is formed on the centrifugal volute.
[0119] In order to improve the sealing performance of the inner cavity. In some embodiments, please refer to Figure 10 , the top surface of the side wall of the air duct support 210 has a first step surface 213 on the outside and a second step surface 214 on the inside. The height of the first step surface 213 is lower than that of the second step surface 214. Please refer to Figure 18, the top surface of the side wall of the air duct cover 220 has an outer third step surface 222 and an inner fourth step surface 223, and the height of the third step surface 222 is higher than that of the fourth step surface 223. Here, the inner side refers to the side close to the inner cavity, and the outer side refers to the side relatively far from the inner cavity.
[0120] The first step surface 213 can be in abutting fit with the third step surface 222, and at the same time, the second step surface 214 is in abutting fit with the fourth step surface 223. In this way, after the air duct cover 220 is covered on the air duct support 210, an abutting seal fit with staggered joints can be formed, ensuring the sealing performance of the entire inner cavity.
[0121] In some embodiments, please refer to Figures 16 - 18 , the air duct fixing cover 230 is arranged on the side of the air duct cover 220 away from the air duct support 210. Specifically, after assembly, the air duct fixing cover is located between the air duct cover 220 and the housing 100.
[0122] The material strength of the air duct fixing cover 230 is greater than that of the air duct cover 220, so it has a certain protection and anti-impact ability.
[0123] The air duct fixing cover 230 can be snap-connected to the air duct cover 220 to form a pre-tightened assembly. Here, it should be noted that the installation process of the air duct fixing cover is as follows: snap-connect the air duct fixing cover 230 to the air duct cover 220 to form a pre-tightened assembly, cover the pre-tightened assembly on the air duct support 210 and press it tightly, and then use fasteners such as screws to fasten the air duct fixing cover 230 on the first support platform 112 and the second support platform 113. In this way, the fastening connection of the air duct fixing cover 230, the air duct cover 220, the air duct support 210 and the chassis 110 is realized.
[0124] By using the air duct fixing cover 230 with relatively greater material strength, the strength of the pre-tightened assembly is improved, and it can resist the pressure impact of the foam air duct in high-pressure tests such as the trampling test and the stacking test. Since the air duct cover 220 and the air duct support 210 are pressed by the air duct fixing cover 230 and the chassis 110, the whole can better resist the vibration and shaking impact during the vehicle operation.
[0125] Among them, the material of the air duct fixing cover 230 can be selected as plastic.
[0126] The specific structure of the snap connection between the air duct fixing cover 230 and the air duct cover 220 is not limited.
[0127] In some embodiments, two concave edges 221 are formed by partial depression on the top surface of the side wall of the air duct cover 220, one of the concave edges 221 is opposite to the first support platform 112, and the other concave edge 221 is opposite to the second support platform 113.
[0128] The opposite side walls of the air duct fixing cover 230 are provided with clamping blocks 231 protruding towards each other. That is to say, the clamping block 231 on one side wall protrudes towards the clamping block 231 on the other side wall, and the clamping block 231 on the other side wall also protrudes towards the clamping block 231 on the above-mentioned one side wall. Among them, two groups of clamping blocks 231 are provided, one group is matched with one concave edge 221, and the other group is matched with the other concave edge 221.
[0129] The air duct fixing cover 230 can elastically deform itself to make the clamping blocks 231 snap into the concave edges 221 respectively, so that the air duct fixing cover 230 is connected to the air duct cover 220 to form a pre-tightened assembly. Specifically, the air duct fixing cover 230 can be bent under the action of an external force, so that the two side walls open and deform, and the distance between the clamping blocks 231 is greater than that of the air duct cover 220. In this way, the air duct fixing cover 230 is arranged on the air duct cover 220, and then the external force is removed to make the air duct fixing cover 230 recover, so that the two clamping blocks 231 move relatively and snap into the concave edges 221. The above assembly action is simple and fast, without any fixing operation and fasteners, and the efficiency is extremely high.
[0130] In some embodiments, the assembly process of the cross-flow air duct assembly is as follows:
[0131] Please refer to Figure 5 , directly place the air duct support 210 downward from the upper part of the chassis 110. Due to the limitation of the first support platform 112 and the second support platform 113 of the chassis 110, the two mounting openings 210a of the air duct support 210 can be accurately centered with the first support platform 112 and the second support platform 113, and the air duct support 210 is assembled onto the chassis 110. The state shown in Figure 6 is formed.
[0132] Furthermore, place the evaporator 203 downward from above the air duct support 210 into the water receiving tray 211, and it is supported and fixed by passing through the third support platform 114 of the chassis 110 through the air duct support 210. Place the bearing seat 204, the cross-flow air wheel 201 and the fan 202 together downward from the upper part of the air duct support 210 into the corresponding assembly positions, that is, the bearing seat 204 is pressed and snapped into the bearing seat installation groove at the top of the first support platform 112 of the chassis 110, the fan 202 is placed into the fan installation groove at the top of the second support platform 113 of the chassis 110, and the cross-flow air wheel 201 between the two is automatically limited and rotatably fixed by the two. Then insert one end of each of the two fan pressing plates 205 into the fan pressing plate insertion holes at the top of the second support platform 113, press the other end of the fan pressing plate 205 and fasten it with screws in the fan pressing plate screw positions at the top of the second support platform 113 to realize the pressing and fastening assembly of the fan 202 on the chassis 110. The assembly state at this time is as shown in Figure 7 is shown.
[0133] Please refer to Figure 21, compared with the cross-flow air duct assembly, during the assembly process of the centrifugal air duct assembly, the fan 202 of the original cross-flow air duct assembly is fixedly installed on the chassis 110 through the fan pressure plate 205. Here, it is necessary to switch to using the fan bracket 208 to be fixedly installed on the second support platform 113 of the chassis 110, and switch the original cross-flow impeller 201 to a centrifugal impeller 201 wrapped by a centrifugal volute and fixed above the first air outlet 200b of the inner cavity. Or design the second support platform 113 of the chassis as the installation slot for the fan.
[0134] Moreover, an air outlet adjustment plate 115 is provided at the indoor air outlet 100b on the chassis 110. The air outlet adjustment plate 115 and the indoor air outlet 100b jointly define a second air outlet adapted to the centrifugal volute of the centrifugal air duct assembly. The air duct support 210 needs to be adjusted to the centrifugal air duct support 210 matching the centrifugal volute. The above structure is shown in Figure 12 this figure.
[0135] When using a centrifugal air duct assembly with a large cooling capacity, the size of the centrifugal impeller 201 is large, resulting in a large height dimension of the centrifugal volute. Therefore, the original air duct cover 220 needs to be adjusted to switch to an air duct cover 220 with a fourth concave cavity. The air duct cover 220 with the above fourth concave cavity is provided with a volute avoidance opening, which is shown in Figure 14 this figure. It should be particularly noted here that if a large-sized centrifugal impeller 201 is not used, the air duct cover 220 here can not be adjusted.
[0136] Please refer to Figures 1 - 22 , the present utility model also provides an air conditioner, which includes a housing 10, an indoor air duct assembly 20 and an outdoor air duct assembly 30.
[0137] The indoor air duct assembly 20 includes an evaporator 203. The indoor air duct assembly 20 is arranged in the inner housing 200, and the indoor air duct assembly 20 is a cross-flow air duct assembly or a centrifugal air duct assembly. The outdoor air duct assembly 30 includes a condenser 301, and the outdoor air duct assembly 30 is arranged in the second area. It can be understood that the indoor air duct assembly 20 can be selectively designed as a cross-flow air duct assembly or a centrifugal air duct assembly according to the use requirements.
[0138] In some embodiments, please refer to Figure 2 and Figure 4 , there is a spaced space between the inner housing 200 and the outdoor air duct assembly 30, and the spaced space can communicate the outdoor air inlet 100c with the outdoor air duct assembly 30. That is to say, the outdoor air flows into the spaced space from the outdoor air inlet 100c and enters the outdoor air duct assembly 30 from here for heat exchange. The above spaced space isolates the inner housing 200 from the outdoor air duct assembly 30, thereby avoiding the vibration friction and direct heat transfer between the two.
[0139] Among them, an electric control component 40 is arranged on one side of the interval space, and a compressor 50 and a refrigeration pipeline system are placed on the other side opposite to the electric control component 40.
[0140] In some embodiments, please refer to Figures 19 - 21 , the indoor air duct assembly 20 is a centrifugal air duct assembly. The centrifugal air duct assembly includes a centrifugal impeller 201 and a centrifugal volute. The centrifugal volute is used for the airflow at the first air inlet to flow into the centrifugal impeller 201, and collects the airflow flowing out of the centrifugal impeller 201 to guide it to the first air outlet. Among them, the centrifugal volute is formed by connecting an upper centrifugal housing 206 and a lower centrifugal housing 207, and the impeller 201 is arranged inside the upper centrifugal housing 206 and the lower centrifugal housing 207.
[0141] The embodiment of the present application also provides a vehicle, including an air conditioner. Among them, please refer to Figure 1 and Figure 2 , the indoor air duct assembly 20 is located in front of the outdoor air duct assembly 30. That is to say, when driving forward, the indoor air duct assembly 20 is in the front and the outdoor air duct assembly 30 is in the rear. The outdoor air outlet 100d is arranged on the rear side wall of the housing 100. The outdoor air inlet 100c is arranged on the side walls on both sides in the width direction of the housing 100.
[0142] The air conditioner further includes an air outlet grille, which is arranged at the outdoor air outlet 100d of the housing 100.
