Description

Technical Field

[0001] The utility model relates to the technical field of air duct components, and in particular to an air duct component and an indoor air conditioner having the same. Background Art

[0002] Currently, in order to achieve greater air output and higher energy efficiency, in the field of air conditioner technology, the air output effect of an air conditioner is usually enhanced by arranging a double cross-flow fan in the air conditioner. A double cross-flow air conditioner generally includes two groups of air ducts and two motors. In order to adapt to the two groups of air ducts and two fans, corresponding adaptation settings need to be made for each structure such as the air outlet frame structure, air duct structure, and air inlet panel structure in the air conditioner.

[0003] However, in order to adapt to the double cross-flow fan, the internal components of the double cross-flow air conditioner inevitably increase, resulting in a more complex installation of its internal structure and a weaker structural integrity. In this way, during transportation, it is easy to occur that structural parts fall off or are damaged due to force impact, which affects the use safety of the air conditioner and increases the pressure of later maintenance.

[0080] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0081] As Figures 1 to 14 shown, Embodiment 1 of the present utility model provides an air duct component. The air duct component is installed in the indoor machine housing. The air duct component includes an air duct main body 10 and a connecting component 20. The connecting component 20 is connected to the air duct main body 10 and is located at the end of the air duct main body 10. The connecting component 20 has a first connecting part 21, a second connecting part 22, and a third connecting part 23 that are sequentially arranged at intervals. The first connecting part 21 and the third connecting part 23 are respectively located at both ends of the connecting component 20. Among them, both the first connecting part 21 and the third connecting part 23 overlap at least part of the indoor machine housing and are connected to the indoor machine housing; the second connecting part 22 is used to connect to a fixed device fixedly installed in the indoor machine housing.

[0082] Using the air duct component provided in the first embodiment of the present utility model, through the settings of the first connection portion 21 and the third connection portion 23 on the air duct component, the air duct component can be interconnected with at least part of the indoor unit housing at at least two locations, and through the setting of the second connection portion 22, the air duct component can be interconnected with other fixing devices within the indoor unit housing. Through such a setting, multiple connections and fixations are formed between the air duct component and at least part of the indoor unit housing and other fixing devices within the indoor unit housing, which can effectively improve the support and fixation effect on the air duct component, form an effective buffer for the possible force impacts on the air duct component, and enhance the integrity and wholeness of the air duct component with the indoor unit housing and other fixing devices within the indoor unit housing. Therefore, through the air duct component provided in this embodiment, the technical problem of the relatively weak internal structure integrity of the double cross-flow air conditioner in the prior art can be solved.

[0083] Specifically, the air duct component is applicable to a double cross-flow air conditioner. Specifically, the air duct main body 10 and the connection component 20 are of an integrally formed structure. In this way, through the setting of the connection component 20, the connection strength between the air duct component and the indoor unit housing and other fixing devices within the indoor unit housing can be enhanced, and the structural layout of the air duct component can be optimized, thereby further improving the support and fixation effect on the air duct component.

[0084] Specifically, the indoor unit housing includes an air inlet panel component 30 and an air outlet panel component 40 which are spliced. The first connection portion 21 and the third connection portion 23 are respectively lapped on both sides of the air inlet panel component 30 or both sides of the air outlet panel component 40. With such a structural setting, through the settings of the first connection portion 21 and the third connection portion 23, the air duct component can be connected to the air inlet panel component 30 and the air outlet panel component 40 of the indoor unit housing, thereby effectively enhancing the structural integrity between the air duct component and the air inlet panel component 30 and the air outlet panel component 40, and further enhancing the support and fixation of the air duct component.

[0085] Specifically, the second connection portion 22 is provided protruding from one side of the first connection portion 21 and the third connection portion 23. With such a structural setting, through the joint settings of the first connection portion 21, the second connection portion 22, and the third connection portion 23, the connection stability between the air duct component and other structures can be enhanced, so as to better buffer the force impacts from various directions.

[0086] Specifically, the distance between the second connection portion 22 and the first connection portion 21 is equal to the distance between the second connection portion 22 and the third connection portion 23. With such a structural setting, through the position settings of the first connection portion 21, the second connection portion 22, and the third connection portion 23, the connection stability between the air duct component and other structures can be enhanced, so as to better buffer the force impacts from various directions.

[0087] In this embodiment, the connecting component 20 includes a first connecting housing 24. The first connecting housing 24 is disposed at the first end of the air duct main body 10. The first connecting housing 24 has a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23 that are sequentially spaced apart. The first connecting portion 21 and the third connecting portion 23 are respectively located at both ends of the first connecting housing 24. Among them, the fixing device includes an air outlet frame component 50 fixedly connected to the indoor unit housing. The second connecting portion 22 is connected to the side of the air outlet frame component 50 close to the air duct component. With such a structural arrangement, the first connecting portion 21 and the third connecting portion 23 provided on the first connecting housing 24 can be connected and fixed to at least a part of the indoor unit housing, and at the same time, the second connecting portion 22 is connected and fixed to the air outlet frame component 50, so as to better support and stabilize the air duct component.

[0088] Specifically, the first connecting housing 24 includes a main housing 241 and a mounting assembly 242 that are connected to each other. The mounting assembly 242 encloses a mounting cavity adapted to the motor 60. Among them, the second connecting portion 22 is disposed opposite to the mounting cavity. With such a structural arrangement, the first connecting housing 24 can support and fix the motor 60. At the same time, since the weight of the motor 60 is relatively heavy, the arrangement of the second connecting portion 22 opposite to the mounting cavity for assembling the motor 60 can better enhance the supporting effect on the motor 60 and enhance the overall strength of the structure.

[0089] Specifically, there are at least two second connecting portions 22, and the at least two second connecting portions 22 are spaced apart from each other. Specifically, there are two motors 60, and there are two mounting assemblies 242. The two mounting assemblies 242 are arranged in one-to-one correspondence with the two motors 60. Two of the at least two second connecting portions 22 are respectively disposed opposite to the two mounting assemblies 242. With such a structural arrangement, the first connecting housing 24 can support and fix the motor 60. At the same time, the one-to-one arrangement of the motor 60, the mounting assembly 242, and the second connecting portion 22 can better enhance the supporting effect on the two motors 60 and enhance the overall strength of the structure.

[0090] Specifically, the first connecting housing 24 includes a main housing 241 and a mounting assembly 242 that are connected to each other. The mounting assembly 242 encloses a mounting cavity adapted to the motor 60. Among them, both sides of the mounting assembly 242 protrude from both sides of the main housing 241. With such a structural arrangement, the protrusion of both sides of the mounting assembly 242 from both sides of the main housing 241 can make the center of gravity position of the motor 60 closer to the center of gravity position of the main housing 241, so as to facilitate more stable support of the motor 60.

[0091] Specifically, in order to better support the motor 60, the mounting assembly 242 is disposed in the middle of the main housing 241.

[0092] Specifically, the first connection housing 24 includes a main housing 241 and a mounting component 242 that are connected to each other. The mounting component 242 encloses a mounting cavity adapted to the motor 60. Among them, the mounting component 242 includes a first mounting portion 2421 and a second mounting portion 2422. The first mounting portion 2421 and the second mounting portion 2422 are detachably connected, and the first mounting portion 2421 and the second mounting portion 2422 are spliced to enclose the mounting cavity. With such a structural arrangement, it is convenient for the assembly between the mounting component 242 and the motor 60, thereby further optimizing the structural layout of the first connection housing 24.

[0093] Specifically, a fourth connection portion 243 is further provided on the first connection housing 24. The fourth connection portion 243 is located on the side of the first connection housing 24 away from the air outlet frame component 50. Among them, the fixing device further includes an evaporator bracket 70 fixedly connected to the indoor unit housing, and the fourth connection portion 243 is fixedly connected to the evaporator bracket 70. With such a structural arrangement, the connection and fixing effect between the air duct component and the evaporator bracket 70 can be enhanced through the setting of the fourth connection portion 243, thereby further enhancing the structural integrity between the air duct component and other fixing devices within the indoor unit housing.

[0094] Specifically, for the convenience of structural layout and connection, the fourth connection portion 243 is provided on the second mounting portion 2422.

[0095] Specifically, the evaporator bracket 70 is made of PP (polypropylene) material. With such a structural arrangement, the evaporator bracket 70 can have good impact resistance and good toughness. Compared with materials such as ABS (acrylonitrile-butadiene-styrene copolymer) or HIPS (high impact polystyrene), the PP material is not likely to produce abnormal noises under the condition of thermal deformation. By fixedly connecting the fourth connection portion 243 to the evaporator bracket 70, the possibility of the air duct component generating abnormal noises due to impact can be reduced.

[0096] Specifically, a side surrounding structure is formed between the air duct component and the air outlet frame component 50. With such a structural arrangement, when the air conditioner experiences a lateral drop during transportation, this surrounding structure can effectively buffer the impact force in the lateral direction.

[0097] Specifically, the indoor unit housing includes an air inlet panel component 30 and an air outlet panel component 40 which are spliced. The first connecting portion 21 and the third connecting portion 23 overlap on both sides of the air inlet panel component 30. The evaporator bracket 70 is located between the air inlet panel component 30 and the duct main body 10. The first connecting housing 24 is also provided with a fifth connecting portion 244 and a sixth connecting portion 245 which are spaced apart and used for connecting with the evaporator bracket 70. The fourth connecting portion 243 is located between the fifth connecting portion 244 and the sixth connecting portion 245. With such a structural arrangement, on the basis of the fourth connecting portion 243, it can be fixedly connected with the evaporator bracket 70 through the fifth connecting portion 244 and the sixth connecting portion 245, enhancing the connection strength between the duct component and the evaporator bracket 70, thereby effectively enhancing the structural integrity between the duct component and the evaporator bracket 70, so as to better support and fix the motor 60 and the duct component.

[0098] Specifically, to enhance the connection strength, the fifth connecting portion 244 and the sixth connecting portion 245 are respectively located at both ends of the first connecting housing 24.

[0099] Specifically, at least one of the fourth connecting portion 243, the fifth connecting portion 244 and the sixth connecting portion 245 is a first plug-in portion, and the evaporator bracket 70 is provided with a second plug-in portion adapted to the first plug-in portion. With such a structural arrangement, the connection stability can be enhanced through the plug-in cooperation between the first plug-in portion and the second plug-in portion.

[0100] Specifically, the fourth connecting portion 243 protrudes from one side of the fifth connecting portion 244 and the sixth connecting portion 245. With such a structural arrangement, through the combined setting of the fourth connecting portion 243, the fifth connecting portion 244 and the sixth connecting portion 245, the connection stability between the duct component and the evaporator bracket 70 can be enhanced, so as to better buffer the force impacts from all directions.

[0101] Specifically, the distance between the fourth connecting portion 243 and the fifth connecting portion 244 is equal to the distance between the fourth connecting portion 243 and the sixth connecting portion 245. With such a structural arrangement, through the position setting of the fourth connecting portion 243, the fifth connecting portion 244 and the sixth connecting portion 245, the connection stability between the duct component and the evaporator bracket 70 can be enhanced, so as to better buffer the force impacts from all directions.

[0102] Specifically, the second connecting portion 22 and the air outlet frame component 50 are connected by screws. Specifically, the first connecting portion 21 and the air inlet panel component 30 are connected by screws. The third connecting portion 23 and the air inlet panel component 30 are connected by screws. Specifically, the fourth connecting portion 243 and the evaporator bracket 70 are connected by a bolt. Specifically, the fifth connecting portion 244 and the evaporator bracket 70 are connected by screws, and the sixth connecting portion 245 and the evaporator bracket 70 are connected by screws. In this way, through multiple different connection methods, the connection effectiveness between the air duct component and the indoor unit housing and the fixing devices can be better enhanced.

[0103] Specifically, as Figure 11 and Figure 12 shown, the first connecting housing 24 has an installation cavity adapted to the motor 60. One end of the first connecting housing 24 away from the air duct main body 10 is provided with a first positioning portion 246. The first positioning portion 246 is disposed opposite to the installation cavity. A second positioning portion 80 adapted to the first positioning portion 246 is provided on the indoor unit housing. The first positioning portion 246 is used for positioning cooperation with the second positioning portion 80. With such a structural arrangement, when the indoor unit drops or other abnormal conditions occur during actual transportation, the motor 60 will swing. Through the cooperation of the first positioning portion 246 and the second positioning portion 80, it is possible to prevent the motor 60 from swinging excessively and deforming.

[0104] Specifically, the first positioning portion 246 and the second positioning portion 80 are respectively a positioning groove and a positioning protrusion. Specifically, both the first positioning portion 246 and the second positioning portion 80 are reinforcing ribs. Specifically, both the first positioning portion 246 and the second positioning portion 80 are circular reinforcing ribs. With such a structural arrangement, no matter which direction the impact comes from, it is possible to buffer through the circular reinforcing ribs, thereby preventing the motor 60 from swinging.

[0105] In the second embodiment of the present utility model, as Figure 15 and Figure 16 shown, the connecting component 20 further includes a second connecting housing 25. The second connecting housing 25 is disposed at the second end of the air duct main body 10. The second connecting housing 25 has a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23 which are sequentially arranged at intervals. The first connecting portion 21 and the third connecting portion 23 are respectively located at both ends of the second connecting housing 25. Among them, the fixing device includes a water receiving tray 90. The second connecting portion 22 is connected to the side of the water receiving tray 90 close to the air duct component. With such a structural arrangement, it is possible to connect and fix at least part of the indoor unit housing through the first connecting portion 21 and the third connecting portion 23 provided on the second connecting housing 25, and at the same time connect and fix the second connecting portion 22 to the water receiving tray 90, thereby better supporting and stabilizing the air duct component.

[0106] Specifically, in the second embodiment of the present utility model, a seventh connecting portion 252 is further provided on the second connecting housing 25. The seventh connecting portion 252 is located on the side of the main housing 251 of the second connecting housing 25 away from the second connecting portion 22. Wherein, the fixing device further includes an air outlet frame component 50 fixedly connected to the indoor unit housing, and the seventh connecting portion 252 is connected to the air outlet frame component 50. With such a structural arrangement, the second connecting housing 25 can be connected and fixed to the air outlet frame component 50 through the seventh connecting portion 252, so as to better support and stabilize the air duct component.

[0107] Specifically, in the second embodiment of the present utility model, a seventh connecting portion 252 is further provided on the second connecting housing 25. The seventh connecting portion 252 is located on the side of the main housing 251 (the first housing) of the second connecting housing 25 away from the second connecting portion 22. Wherein, the seventh connecting portion 252 is provided on the end plate 11 of the air duct main body 10 for enclosing the air cavity. With such a structural arrangement, the connection stability between the air duct main body 10 and the air outlet frame component 50 can be further enhanced, so as to better support and stabilize the air duct component.

[0108] Specifically, in the second embodiment of the present utility model, there are at least two seventh connecting portions 252. One of the at least two seventh connecting portions 252 is arranged between the first connecting portion 21 and the second connecting portion 22, and the other of the at least two seventh connecting portions 252 is arranged between the second connecting portion 22 and the third connecting portion 23. With such a structural arrangement, by setting the position of the seventh connecting portion 252, the connection stability between the second connecting housing 25 and other structures can be optimized, so as to better buffer the force impacts from various directions.

[0109] Specifically, in the second embodiment of the present utility model, there are at least two seventh connecting portions 252. Wherein, the air duct main body 10 has at least two air cavities 12, and the at least two seventh connecting portions 252 are arranged in one-to-one correspondence with the at least two air cavities 12, and each seventh connecting portion 252 is arranged opposite to the corresponding air cavity 12. With such a structural arrangement, since a cross-flow fan blade 130 is arranged in the air cavity 12, by arranging each seventh connecting portion 252 opposite to the corresponding air cavity 12, it is convenient to better support the air duct component through the connection between the seventh connecting portion 252 and the air outlet frame component 50, and the overall strength of the structure is enhanced.

[0110] Specifically, in the second embodiment of the present utility model, an eighth connecting portion 253 and a ninth connecting portion 254 for connecting with the water receiving tray 90 are further spaced apart on the second connecting housing 25, and the second connecting portion 22 is located between the eighth connecting portion 253 and the ninth connecting portion 254. Among them, the eighth connecting portion 253 and the ninth connecting portion 254 are respectively located at both ends of the second connecting housing 25. With such a structural arrangement, the connection and fixation effect between the air duct component and the water receiving tray 90 can be enhanced through the settings of the eighth connecting portion 253 and the ninth connecting portion 254, thereby further enhancing the structural integrity between the air duct component and other fixing devices within the indoor unit housing.

[0111] In the second embodiment, an eighth connecting portion 253 and a ninth connecting portion 254 for connecting with the water receiving tray 90 are further spaced apart on the second connecting housing 25, and the second connecting portion 22 is located between the eighth connecting portion 253 and the ninth connecting portion 254. Among them, at least one of the eighth connecting portion 253 and the ninth connecting portion 254 forms a third insertion portion, and a fourth insertion portion adapted to the third insertion portion is provided on the water receiving tray 90. With such a structural arrangement, the connection stability can be enhanced through the insertion fit between the third insertion portion and the fourth insertion portion.

[0112] Specifically, in the second embodiment of the present utility model, the water receiving tray 90 is made of PP (polypropylene) material. With such a structural arrangement, the water receiving tray 90 can have better impact resistance and better toughness. Compared with materials such as ABS (acrylonitrile-butadiene-styrene copolymer) or HIPS (high impact polystyrene), the PP material is not likely to produce abnormal noises under the condition of thermal deformation. By fixedly connecting the second connecting portion 22, the eighth connecting portion 253, and the ninth connecting portion 254 with the water receiving tray 90, the possibility of the air duct component generating abnormal noises due to impact can be reduced.

[0113] In the second embodiment, the connection between the second connecting portion 22 and the water receiving tray 90 is a screw connection. Specifically, the connection between the first connecting portion 21 and the air inlet panel component 30 is a screw connection. The connection between the third connecting portion 23 and the air inlet panel component 30 is a screw connection. Specifically, the connection between the seventh connecting portion 252 and the air outlet frame component 50 is a screw connection. Specifically, the connection between the eighth connecting portion 253 and the water receiving tray 90 is a pin connection, and the connection between the ninth connecting portion 254 and the water receiving tray 90 is a pin connection. In this way, through multiple different connection methods, the connection effectiveness between the air duct component and the indoor unit housing and the fixing devices can be better enhanced.

[0114] In the first embodiment of the present utility model, as Figure 14As shown in the figure, the fixing device includes an air outlet frame member 50 fixedly connected to the indoor unit housing. The air duct main body 10 includes a first arc plate 13 and a second arc plate 14 connected to each other. One end of the first arc plate 13 is spaced from one end of the second arc plate 14, and the other end of the first arc plate 13 is spaced from the other end of the second arc plate 14. The first arc plate 13 is used to enclose a first air cavity 121, and the second arc plate 14 is used to enclose a second air cavity 122. The air duct main body 10 further includes a mounting connection portion 15 provided between one end of the first arc plate 13 and one end of the second arc plate 14. The mounting connection portion 15 is located on the side of the air duct main body 10 close to the air outlet frame member 50, and the mounting connection portion 15 is connected to the air outlet frame member 50. With such a structural arrangement, the connection stability between the air duct member and the air outlet frame member 50 can be enhanced through the connection between the mounting connection portion 15 and the air outlet frame member 50, thereby further enhancing the structural integrity between the air duct member and the fixing device within the indoor unit housing.

[0115] Specifically, the connection mode of the first arc plate 13 and the second arc plate 14 forms a double-V-shaped support structure.

[0116] In the first embodiment, the air duct main body 10 further includes a first bending member 16. The first bending member 16 is connected to one end of the first arc plate 13, and at least part of the first bending member 16 is disposed opposite to the first air cavity 121. The first bending member 16 is used for splicing with one side of the air outlet frame member 50. With such a structural arrangement, the connection stability between the air duct member and the air outlet frame member 50 can be enhanced through the connection between the first bending member 16 and the air outlet frame member 50, thereby further enhancing the structural integrity between the air duct member and the fixing device within the indoor unit housing. Moreover, with such an arrangement, through the splicing cooperation between the structure of the air duct member and the structure of the air outlet frame member 50, the material consumption and weight of the air duct member can be reduced on the premise of ensuring the sealing performance of the air cavity 12, and the production cost can be further reduced.

[0117] In the first embodiment, the air duct main body 10 further includes a second bending member 17. The second bending member 17 is connected to one end of the second arc plate 14, and at least part of the second bending member 17 is disposed opposite to the second air cavity 122. The second bending member 17 is used for splicing with the other side of the air outlet frame member 50. With such a structural arrangement, the connection stability between the air duct member and the air outlet frame member 50 can be enhanced through the connection between the second bending member 17 and the air outlet frame member 50, thereby further enhancing the structural integrity between the air duct member and the fixing device within the indoor unit housing. Moreover, with such an arrangement, through the splicing cooperation between the structure of the air duct member and the structure of the air outlet frame member 50, the material consumption and weight of the air duct member can be reduced on the premise of ensuring the sealing performance of the air cavity 12, and the production cost can be further reduced.

[0118] As Figure 5 and Figure 6 shown, in the first embodiment of the present utility model, the air duct component further includes a connecting rod 100, a swing blade 110, a volute tongue 120, and a cross-flow fan blade 130. The connecting rod 100 is drivingly connected to the swing blade 110. The swing blade 110 is disposed on the volute tongue 120. The volute tongue 120 is assembled on the air duct main body 10. The cross-flow fan blade 130 is disposed in the air cavity 12. Specifically, the motor 60 further includes a motor cover 61. Specifically, there are at least four swing blades 110, and there are also at least four volute tongues 120. In this way, a better air supply effect can be achieved.

[0119] In the third embodiment of the present utility model, as Figure 15 and Figure 17 shown, the connecting component 20 includes a connecting assembly 26. The connecting assembly 26 is disposed between the two ends of the air duct main body 10. The connecting assembly 26 has a first connecting portion 21 and a third connecting portion 23 which are spaced apart. The first connecting portion 21 and the third connecting portion 23 are respectively located at the two ends of the connecting assembly 26. Among them, the indoor unit housing includes an air inlet panel component 30 and an air outlet panel component 40 which are spliced. The first connecting portion 21 and the third connecting portion 23 are respectively lapped on both sides of the air inlet panel component 30. With such a structural arrangement, through the setting of the connecting assembly 26, the connection strength between the air duct component and the indoor unit housing can be further enhanced, thereby enhancing the structural integrity between the air duct component and the indoor unit housing, and further better buffering the force on the air duct component.

[0120] In the third embodiment, in order to achieve better force buffering, the connecting assembly 26 is disposed in the middle of the air duct main body 10. Specifically, there are multiple connecting assemblies 26, and the multiple connecting assemblies 26 are spaced apart along the extending direction of the air duct main body 10. The distance between two adjacent connecting assemblies 26 is greater than 400 mm and less than 600 mm. In this way, when the air duct component is relatively long, the support for the air duct component can be enhanced through the setting of the multiple connecting assemblies 26.

[0121] Embodiment 4 of the present utility model provides an indoor air conditioner, which includes the air duct components in Embodiment 1, Embodiment 2, and Embodiment 3. By using the indoor air conditioner provided in Embodiment 4 of the present utility model, through the settings of the first connection part 21 and the third connection part 23 on the air duct component, the air duct component can be connected to at least part of the indoor unit housing at at least two places, and through the setting of the second connection part 22, the air duct component can be connected to other fixing devices inside the indoor unit housing. Through such a setting, multiple connections and fixings are formed between the air duct component and at least part of the indoor unit housing and other fixing devices inside the indoor unit housing, which can effectively improve the support and fixing effects on the air duct component, form an effective buffer for the possible force impacts on the air duct component, and enhance the integrity and wholeness of the air duct component, the indoor unit housing, and other fixing devices inside the indoor unit housing. Therefore, through the indoor air conditioner provided in this embodiment, the technical problem of the relatively weak integrity of the internal structure of the existing double cross-flow air conditioner can be solved.

[0122] Specifically, the indoor air conditioner is a double cross-flow indoor air conditioner.

[0123] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: By setting assembly structures at the upper and lower ends of the double cross-flow air duct, combined with the double V-shaped support structure, the force on the air duct is dispersed at multiple points, and a three-layer buffer structure is adopted to effectively buffer the impact in the high-rise direction in multiple layers. The air duct and the air outlet frame form a lateral surrounding structure, further strengthening the structural strength and achieving a better support effect with less material for the air duct. Through the circular structure of the top cover, the deformation and sway of the assembled motor parts are controlled, effectively buffering the impact force during transportation and handling. The pin is assembled onto the evaporator bracket and the water receiving tray, and the reduction of abnormal noise is achieved by using the evaporator bracket and the water receiving tray that can be made of PP material.
