Description

Technical Field

[0001] This application relates to the technical field of air conditioners, and particularly to an indoor unit of an air conditioner. Background Art

[0002] Currently, a wind deflector is usually provided at the first air outlet of an indoor unit of an air conditioner. The wind deflector can not only adjust the direction of the air output from the first air outlet to the room, but also close the first air outlet when the indoor unit of the air conditioner is not working, so as to maintain the aesthetics of the indoor unit of the air conditioner, and at the same time prevent dust and the like from entering the inside of the casing from the first air outlet.

[0003] In a wall-mounted indoor unit of an air conditioner, the wind deflector opens or closes the first air outlet in a rotatable manner along the length direction of the casing. The two ends of the wind deflector along the length direction of the casing are correspondingly arranged with the two side edges of the first air outlet along the length direction of the casing, and there is a fitting gap between the end of the wind deflector and the corresponding edge of the first air outlet to ensure reliable rotation of the wind deflector. Inevitably, the wind deflector will shift along the length direction of the casing during the rotation process, resulting in different sizes of the two fitting gaps between the wind deflector and the first air outlet, which will not only affect the overall aesthetics of the indoor unit of the air conditioner, but also affect the normal operation of the wind deflector.

[0004] In some wall-mounted indoor units of air conditioners, a limiting structure is usually provided to limit the connection position of the wind deflector and the casing to prevent the wind deflector from shifting along the length direction of the casing. However, in the prior art, the positioning accuracy of the limiting structure for the wind deflector is poor, and in some wall-mounted indoor units of air conditioners, the length dimension of the indoor unit of the air conditioner is relatively large, and the length dimension of the wind deflector is also relatively large, resulting in the wind deflector being prone to shaking relative to the casing during rotation, which not only affects the air outlet stability, but also increases the offset amount of the wind deflector along the length direction of the casing.

[0005] In view of this, this application is proposed. Summary of the Invention

[0006] Aiming at the deficiencies in the related art, this application provides an indoor unit of an air conditioner. By providing a support member at the first air outlet to support the rotation of the wind deflector, the smoothness of the rotation of the wind deflector is increased, and the position of the wind deflector along the length direction of the casing is adjusted by using the support member to prevent the wind deflector from shifting along the length direction of the casing.

[0164] It should be noted that the brief description of terms in this application is only for facilitating the understanding of the subsequent described implementation manners, rather than intending to limit the implementation manners of this application. Unless otherwise specified, these terms should be understood in their ordinary and general meanings.

[0165] In this application, terms such as "first", "second", "third", etc. in the specification, claims and the above-mentioned drawings are used to distinguish similar or same-kind objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that such terms can be interchanged under appropriate circumstances.

[0166] The terms "include" and "have" and any of their variations are intended to cover but not exclusively include. For example, a product or device including a series of components does not necessarily have to be limited to all the clearly listed components, but may include other components not clearly listed or inherent to these products or devices.

[0167] The air conditioner indoor unit provided by the implementation manner of this application can have various implementation forms.

[0168] As Figure 1-113 shown, a wall-mounted air conditioner indoor unit provided by this application includes a housing 100, a heat exchanger 300, a heat exchange fan, and a display component.

[0169] As Figure 1 , Figure 2 , Figure 4 shown, the housing 100 is used to form the overall appearance of the air conditioner indoor unit.

[0170] The housing 100 has a top and a bottom. The top of the housing 100 and the bottom of the housing 100 are opposite ends, and the direction from the top of the housing 100 to the bottom of the housing 100 is the height direction of the housing 100.

[0171] The left side of the housing 100 and the right side of the housing 100 are opposite sides, and the direction from the left side of the housing 100 to the right side of the housing 100 is the length direction of the housing 100.

[0172] The front side and the rear side of the housing 100 are opposite sides, and the direction from the front side of the housing 100 to the rear side of the housing 100 is the thickness direction of the housing 100.

[0173] In practical applications, the housing 100 is usually arranged at the top of the room or in the upper space of the room. Among them, the rear side of the housing 100 faces the wall, and the front side of the housing 100 faces the user.

[0174] A heat exchange channel is defined inside the housing 100, and the heat exchanger 300 and the heat exchange fan are arranged in the heat exchange channel to exchange heat with the air entering the heat exchange channel.

[0175] The housing 100 includes a first air inlet 101, and the first air inlet 101 is communicated with the heat exchange channel, and the indoor air enters the heat exchange channel through the first air inlet 101.

[0176] The housing 100 may include a first air outlet 102, and the first air outlet 102 is communicated with the heat exchange channel, and the air in the heat exchange channel is output to the room through the first air outlet 102.

[0177] The indoor air enters the heat exchange channel through the first air inlet 101 and is output to the room through the first air outlet 102.

[0178] The first air inlet 101 is located at the top of the housing 100, and the first air inlet 101 extends along the length direction of the housing 100.

[0179] The first air outlet 102 is opened on the front side of the housing 100 and is arranged close to the bottom of the housing 100, that is, the first air outlet 102 is located at the front lower side of the housing 100.

[0180] The first air outlet 102 extends along the length direction of the housing 100.

[0181] As Figure 6 shown, the housing 100 includes an outer cover 110. A first cavity with an opening facing the rear side of the housing 100 is defined inside the outer cover 110, and the heat exchanger 300 and the heat exchange fan are located in the first cavity.

[0182] In some embodiments, the first air inlet 101 is opened on the top of the outer cover 110.

[0184] A first opening 114 is provided at the bottom of the front side of the outer cover 110, and a second opening 149 is provided at the bottom of the front side of the base 140. The second opening 149 is arranged corresponding to the first opening 114 to jointly define the first air outlet 102.

[0185] The outer cover 110 has a frame structure. On the one hand, it can facilitate the contact between the heat exchanger 300 and the air inside the casing 100. On the other hand, it can reduce the weight of the outer cover 110.

[0186] An air inlet grille is provided at the first air inlet 101 to prevent dust or debris from entering the inside of the casing 100 through the first air inlet 101.

[0187] In some embodiments, the air inlet grille is integrally injection-molded with the outer cover 110.

[0188] To avoid shrinkage of the appearance of the outer cover 110 during injection molding, a process shrinkage groove is usually provided at the air inlet grille. However, the process shrinkage groove will affect the structural strength of the air inlet grille. If the process shrinkage groove is provided in the area where the outer cover 110 is subjected to greater force, it may cause the outer cover 110 to crack.

[0189] As Figure 3 shown, a first reinforcing rib 112 is provided on the outer cover 110. The first reinforcing rib 112 is provided at the first air inlet 101 and is used to increase the strength of the outer cover 110.

[0190] The first reinforcing rib 112 extends in the direction from the front side to the rear side of the casing 100 so that the first reinforcing rib 112 is connected to both edges of the first air inlet 101 extending in the length direction of the casing 100.

[0191] It should be noted that the first reinforcing rib 112 is provided in the area where the outer cover 110 and the base 140 cooperate and are subjected to greater force.

[0192] As Fig.24 shown, the casing 100 may include a second air inlet 121. The second air inlet 121 is communicated with the heat exchange channel, and indoor air can enter the heat exchange channel through the second air inlet 121.

[0213] The communication portion 117 is arranged along the length direction of the housing 100. The air entering the transition cavity 103 from the second air inlet 121 passes through the communication portion 117 and enters the first cavity.

[0214] In some embodiments, the communication portion 117 is a through opening formed in the outer cover 110. When the side cover 120 is connected to the outer cover 110, the end of the second support portion 122 away from the side cover 120 extends into the communication portion 117.

[0215] In some other embodiments, the first support portion 116 is arranged at the outer edge of the communication portion 117 to increase the strength of the side wall of the outer cover 110 where the communication portion 117 is provided.

[0216] As Fig.18 and Fig.23 shown, the outer cover 110 is provided with a first clamping portion 115. The first clamping portion 115 is arranged on the side of the outer cover 110 facing the side cover 120.

[0217] The side cover 120 is provided with a second clamping portion 123. The second clamping portion 123 is arranged on the side of the side cover 120 facing the outer cover 110.

[0218] The second clamping portion 123 and the first clamping portion 115 are correspondingly disposed and cooperate with each other, so that the side cover 120 and the outer cover 110 are connected to each other.

[0219] In some embodiments, the second clamping portion 123 is a hook, and the first clamping portion 115 is, and the second clamping portion 123 passes through the first clamping portion 115 and cooperates with the outer edge of the first clamping portion 115 to connect the second clamping portion 123 and the first clamping portion 115 to each other.

[0220] like Fig.15 As shown, the air conditioner indoor unit may include two decorative parts 130 , and the two decorative parts 130 are arranged in a one-to-one correspondence with the two side covers 120 .

[0221] The trim 130 is detachably connected to the corresponding side cover 120 and the outer cover 110 .

[0222] The decorations 130 are located at two side edges of the first air outlet 102 along the length direction of the housing 100 .

[0223] By providing the decorative part 130, on the one hand, the firmness of the side cover 120 when installed on the outer cover 110 can be increased, and on the other hand, the overall aesthetics of the air conditioner indoor unit can be increased.

[0224] It should be noted that the two decorative parts 130 are mirror images of each other.

[0225] like Fig.26 As shown, the trim 130 includes a first contact portion 131 , and the first contact portion 131 and the side cover 120 are in contact with each other.

[0226] The trim 130 may include a second contact portion 132 intersecting the first contact portion 131 ; the second contact portion 132 is in contact with the front side of the outer cover 110 .

[0227] The second contact portion 132 is provided with a third clamping portion 1321 . The third clamping portion 1321 is provided at one side of the second contact portion 132 facing the front side of the outer cover 110 .

[0230] The first contact portion 131 is provided with a fifth engaging portion 1311, and the fifth engaging portion 1311 is provided on the side of the first contact portion 131 facing the side cover 120.

[0231] The outer cover 110 is provided with a sixth engaging portion 1113, and the sixth engaging portion 1113 is provided on the side of the outer cover 110 facing the side cover 120;

[0232] The side cover 120 is provided with a through portion 124. The fifth engaging portion 1311, the through portion 124, and the sixth engaging portion 1113 are correspondingly arranged. The fifth engaging portion 1311 passes through the through portion 124 and cooperates with the sixth engaging portion 1113 to connect the decorative member 130, the side cover 120, and the outer cover 110 to each other.

[0233] In some embodiments, as Fig.24 shown, the outer cover 110 is provided with a first positioning portion 118. The first positioning portion 118 is correspondingly arranged with the through portion 124. The first positioning portion 118 passes through the through portion 124 to position the connection position between the outer cover 110 and the side cover 120.

[0234] In some other embodiments, the first positioning portions 118 are provided in plurality, and the plurality of first positioning portions 118 are distributed on the side of the outer cover 110 facing the side cover 120 to increase the accuracy of the positioning result of the connection position between the outer cover 110 and the side cover 120.

[0235] It should be noted that the first engaging portions 115 and the second engaging portions 123 are also provided in plurality, and the plurality of first engaging portions 115 and the plurality of second engaging portions 123 are arranged in one-to-one correspondence to increase the connection strength between the outer cover 110 and the side cover 120.

[0236] In some embodiments, one first positioning portion 118 is provided at the outer edge of one of the first engaging portions 115. Since the first engaging portion 115 is connected to the second engaging portion 123, accordingly, the corresponding second engaging portion 123 is also located at the outer edge of one of the through portions 124, so that the first positioning portion 118 can pass through the through portion 124 and the first engaging portion 115 and the second engaging portion 123 can also be connected to each other.

[0237] In some embodiments, as Fig.25 shown, the outer cover 110 is further provided with a second positioning portion 1112, and the second positioning portion 1112 is located at the connection between the outer cover 110 and the decorative member 130.

[0238] As Fig.29 shown, the decorative member 130 is provided with a first positioning block 1322. The first positioning block 1322 is located on the side of the decorative member 130 facing the outer cover 110 and at the bottom of the decorative member 130. The first positioning block 1322 cooperates with the second positioning portion 1112 to position the connection position between the outer cover 110 and the decorative member 130.

[0239] In some embodiments, such as Fig.26 shown, the trim piece 130 is provided with a third positioning portion 1312, the third positioning portion 1312 is correspondingly arranged with the through portion 124, and the third positioning portion 1312 is arranged through the through portion 124 to position the connection position of the trim piece 130 and the side cover 120.

[0240] In some embodiments, on the side of the side cover 120 facing the transition cavity 103, a third support portion 126 is provided. The third support portion 126 is in contact with the side wall of the outer cover 110 facing the transition cavity 103 to support the side cover 120 and the outer cover 110, and increase the connection strength between the side cover 120 and the outer cover 110.

[0241] In some other embodiments, the third support portion 126 is located above the second support portion 122.

[0242] By the operation of the heat exchange fan, a part of the indoor air enters the heat exchange channel from the first air inlet 101 and contacts the heat exchanger 300, and another part of the indoor air enters the heat exchange channel through the transition cavity 103 from the second air inlet 121 and contacts the heat exchanger 300. The heat exchanger 300 exchanges heat with the indoor air in the heat exchange channel to form air-conditioning air, and the air-conditioning air is output to the indoor through the first air outlet 102.

[0243] Such as Fig.10 shown, the housing 100 may include a front panel 150. The front panel 150 is arranged on the front side of the outer cover 110 and is detachably connected to the outer cover 110.

[0244] By arranging the front panel 150 to be detachably connected to the outer cover 110, when a failure occurs in the indoor unit of the air conditioner, the front panel 150 can be disassembled to check the internal situation of the housing 100.

[0245] It should be noted that the front panel 150 is located above the first air outlet 102.

[0246] Since the front panel 150 is detachably connected to the outer cover 110, there is inevitably a certain gap between the front panel 150 and the front side of the outer cover 110, and the front panel 150 is located above the first air outlet 102. Therefore, when the air-conditioning air is output to the indoor through the first air outlet 102, it is easy to flow into the gap, causing condensation on the side of the front panel 150 facing the outer cover 110 and affecting the operation of components such as the heat exchanger 300.

[0247] In this embodiment, a receiving portion 113 is provided on the front side of the outer cover 110. The receiving portion 113 is located above the first air outlet 102 and extends along the length direction of the housing 100.

[0248] Such as Fig.11As shown, the front panel 150 is provided with a convex rib 151 , and the convex rib 151 extends along the length direction of the housing 100 .

[0249] The convex rib 151 is arranged corresponding to the accommodating portion 113. The convex rib 151 is arranged in the accommodating portion 113 to seal the gap between the front panel 150 and the front side of the outer cover 110 to prevent air conditioning wind from entering the gap, thereby preventing condensation from occurring on the side of the front panel 150 facing the outer cover 110.

[0250] It should be noted that the rib 151 is disposed close to a side of the front panel 150 facing the bottom of the housing 100 .

[0251] In some embodiments, the rib 151 is located at an outer edge of the front panel 150 facing the bottom of the housing 100 .

[0252] The outer cover 110 is connected to the base 140 by fasteners such as bolts or screws.

[0253] The outer cover 110 is provided with a first connection hole 106 , and the base 140 is provided with a second connection hole 1414 . The fastener is provided in both the first connection hole 106 and the second connection hole 1414 , so that the outer cover 110 and the base 140 are connected to each other.

[0254] In order to prevent the fasteners from being exposed on the surface of the outer cover 110 or the base 140 to affect the aesthetics of the air conditioner indoor unit, and also to protect the fasteners, the fasteners are usually hidden.

[0255] Specifically, Fig.31 As shown, the outer cover 110 is provided with a third connecting portion 1115, and the third connecting portion 1115 defines a accommodating cavity 104, and the accommodating cavity 104 is provided with an accommodating cavity opening. When the outer cover 110 and the base 140 are connected to each other through a fastener, one end of the fastener away from the first connecting hole 106 is arranged in the accommodating cavity 104 to hide the fastener.

[0256] By arranging one end of the fastener away from the first connecting hole 106 in the accommodating cavity 104, the fastener can be hidden to prevent the fastener from affecting the aesthetics of the air conditioner indoor unit, and the fastener can be prevented from contacting dust and the like, thereby protecting the fastener.

[0257] In some embodiments, the opening of the accommodating cavity is arranged roughly toward the front side of the housing 100; the first connecting hole 106 is arranged on the cavity wall of the accommodating cavity 104 on the opposite side of the accommodating cavity opening, so that the fastener passes through the accommodating cavity 104 from the accommodating cavity opening and passes through the first connecting hole 106 to connect with the base 140.

[0258] By opening a receiving cavity 104 in the third connecting portion 1115, one end of the fastener away from the first connecting hole 106 is arranged in the receiving cavity 104 to hide the fastener and prevent the fastener from protruding from the surface of the outer cover 110. On the one hand, it is to prevent the fastener from affecting the aesthetics of the air-conditioning indoor unit. On the other hand, the fastener can also be protected to prevent the fastener from affecting the connection effect between the outer cover 110 and the base 140 due to corrosion or the like.

[0259] Although the third connection portion 1115 has a receiving cavity 104 to hide the fasteners, it will also affect the aesthetics of the air conditioner indoor unit, and dust and impurities can easily enter the receiving cavity 104 through the receiving cavity opening to damage the fasteners. Fig. 9 As shown, a cover 700 is usually provided at the opening of the accommodating cavity to close the accommodating cavity 104, to avoid affecting the aesthetics of the air conditioner indoor unit due to the provision of the accommodating cavity 104, and to protect and further hide the fasteners.

[0260] When the cover 700 opens the accommodating cavity 104, the cover 700 is easily lost due to lack of restraint. Fig.36 As shown, the cover 700 is provided with a cantilever 710 , so that the housing 100 can constrain the cover 700 through the cantilever 710 , thereby preventing the cover 700 from being lost.

[0261] In this embodiment, the cover 700 opens or closes the accommodating cavity 104 in a rotatable manner, wherein one end of the cantilever 710 is connected to a side of the cover 700 facing the accommodating cavity 104 , and the other end of the cantilever 710 is rotatably connected to the third connecting portion 1115 .

[0262] If the cover 700 has a small rotation angle when opening the receiving cavity 104, the cover 700 may affect the installation and removal of the fastener. Although the rotation angle of the cover 700 can be increased by increasing the length of the cantilever 710, considering the limited volume of the receiving cavity 104, when the cover 700 closes the opening of the receiving cavity, the cantilever 710 with a larger size may interfere with the cavity wall of the receiving cavity 104.

[0263] In view of this, in this embodiment, if Figure 33-Figure 35 As shown, a first outlet portion 105 is provided in the cavity wall of the accommodating cavity 104 so that one end of the cantilever 710 away from the cover 700 can pass through the accommodating cavity 104 through the first outlet portion 105 to prevent the cantilever 710 from interfering with the cavity wall of the accommodating cavity 104, thereby increasing the rotation angle of the cover 700 and preventing the cover 700 from affecting the installation and removal of the fastener.

[0264] like Fig.34 and Fig.35 As shown, one end of the cantilever 710 away from the cover 700 is disposed outside the accommodating cavity 104 through the first protruding portion 105 .

[0265] When the cover 700 opens the accommodation cavity 104, the end of the cantilever 710 away from the cover 700 moves towards the cavity wall of the accommodation cavity 104 where the first penetration part 105 is opened.

[0266] When the cover 700 closes the accommodation cavity 104, the end of the cantilever 710 away from the cover 700 moves away from the cavity wall of the accommodation cavity 104 where the first penetration part 105 is opened.

[0267] By providing the first penetration part 105 on the cavity wall of the accommodation cavity 104, the end of the cantilever 710 away from the cover 700 passes through the first penetration part 105 and is provided outside the accommodation cavity 104, so that the indoor unit of the air conditioner can increase the rotation angle when the cover 700 opens the accommodation cavity 104 by increasing the length dimension of the cantilever 710, thereby preventing the cover 700 from affecting the installation and disassembly of the fastener.

[0268] As Fig.34 and Fig.35 As shown, a blocking part 713 is provided at the end of the cantilever 710 provided outside the accommodation cavity 104. The blocking part 713 is located outside the accommodation cavity 104 and cooperates with the outer edge of the first penetration part 105 to prevent the end of the cantilever 710 provided outside the accommodation cavity 104 from passing back through the first penetration part 105 into the accommodation cavity 104, so as to prevent the cantilever 710 from separating from the third connection part 1115.

[0269] When the cover 700 opens the accommodation cavity 104, the end of the cantilever 710 away from the cover 700 moves towards the accommodation cavity 104. When the blocking part 713 comes into contact with the outer edge of the first penetration part 105, the cantilever 710 moves to the limit position and cannot continue to move towards the accommodation cavity 104. At this time, the cover 700 is at the maximum rotation angle when the accommodation cavity 104 is opened.

[0270] By providing the blocking part 713 at the end of the cantilever 710 away from the cover 700, the blocking part 713 abuts against the outer edge of the first penetration part 105 to prevent the end of the cantilever 710 away from the cover 700 from passing through the first penetration part 105 and causing the cantilever 710 to lose the constraint with the cavity wall of the accommodation cavity 104.

[0271] As Fig.36 shown, the cantilever 710 is provided with a first limiting part 712, and the first limiting part 712 is arranged close to the cover 700.

[0272] When the cover 700 closes the accommodation cavity 104, the first limiting part 712 is located outside the accommodation cavity 104 by the first penetration part 105 and contacts the outer edge of the first penetration part 105 to prevent the cantilever 710 from moving, so that the cover 700 can reliably close the accommodation cavity 104.

[0273] By providing a first limiting portion 712 on the cantilever 710 and using the first limiting portion 712 to abut against the outer edge of the first passing portion 105, the cover 700 can be kept in a state of closing the accommodation cavity 104, thereby increasing the reliability of the cover 700 in closing the accommodation cavity 104.

[0274] It should be noted that under the action of an external force, the first limiting portion 712 is disposed outside the accommodation cavity 104 from inside the accommodation cavity 104 through the deformation of the first limiting portion 712 and / or the outer edge of the first passing portion 105. This belongs to the well-known common sense technology in the art and will not be elaborated here.

[0275] As Fig.37 shown, the cantilever 710 is further provided with a second limiting portion 711. The second limiting portion 711 is disposed near one end of the cantilever 710 away from the cover 700, and the second limiting portion 711 cooperates with the outer edge of the accommodation cavity opening.

[0276] When the blocking portion 713 comes into contact with the outer edge of the first passing portion 105, the second limiting portion 711 is located outside the accommodation cavity 104 and contacts the outer edge of the accommodation cavity opening to prevent the cantilever 710 from moving, so that the cover 700 can reliably open the accommodation cavity 104.

[0277] It should be noted that under the action of an external force, the second limiting portion 711 is disposed outside the accommodation cavity 104 from inside the accommodation cavity 104 through the deformation of the second limiting portion 711 and / or the outer edge of the accommodation cavity opening. This belongs to the well-known common sense technology in the art and will not be elaborated here.

[0278] In this embodiment, when the cover 700 closes the accommodation cavity 104, the second limiting portion 711 needs to be disposed inside the accommodation cavity 104 from the accommodation cavity opening, and then disposed outside the accommodation cavity 104 by the first passing portion 105. The first limiting portion 712 also needs to be disposed inside the accommodation cavity 104 from the accommodation cavity opening, and then disposed outside the accommodation cavity 104 by the first passing portion 105.

[0279] By providing the second limiting portion 711 and using the second limiting portion 711 to abut against the outer edge of the accommodation cavity opening, the cover 700 can be kept in a state of opening the accommodation cavity 104, increasing the reliability of the cover 700 in opening the accommodation cavity 104, thereby facilitating the installation or disassembly of the fastener.

[0280] It should be noted that when the first limiting portion 712 passes through the first passing portion 105, it will make a sound and generate vibration. When the first limiting portion 712 passes through the accommodation cavity opening, it will also make a sound and generate vibration; when the second limiting portion 711 passes through the accommodation cavity opening, it will make a sound and generate vibration. When the second limiting portion 711 passes through the first passing portion 105, it will also make a sound and generate vibration.

[0281] In some embodiments, when the first limiting portion 712 is disposed outside the accommodation cavity 104 by the first passing portion 105, it is determined that the cover 700 is closed in place.

[0282] In some embodiments, when the second limiting portion 711 contacts the outer edge of the opening of the accommodation cavity, it is determined that the cover 700 is opened in place.

[0283] During the installation of the air conditioner indoor unit, since the size of the cover 700 is small, it is not convenient for the operator to observe whether the cover 700 is closed in place or opened in place. The operator can judge the state of the cover 700 according to the sound and / or vibration.

[0284] It should be noted that when the cover 700 closes the accommodation cavity 104, the second limiting portion 711 needs to be disposed inside the accommodation cavity 104 from the opening of the accommodation cavity, and then disposed outside the accommodation cavity 104 by the first passing portion 105. The first limiting portion 712 also needs to be disposed inside the accommodation cavity 104 from the opening of the accommodation cavity, and then disposed outside the accommodation cavity 104 by the first passing portion 105. Therefore, when the cover 700 closes the accommodation cavity 104, usually four sounds and four vibrations will be generated; when the cover 700 opens the accommodation cavity 104, usually four sounds and four vibrations will also be generated.

[0285] In order to increase the binding force between the third connecting portion 1115 and the cover 700, two cantilevers 710 are provided. The two cantilevers 710 are correspondingly arranged. On the sides of the two cantilevers 710 facing away from each other, a blocking portion 713, a first limiting portion 712 and a second limiting portion 711 are respectively provided.

[0286] Correspondingly, the first passing portion 105 is also provided with two, and the two first passing portions 105 are arranged in one-to-one correspondence with the two cantilevers 710.

[0287] It should be noted that in some embodiments, the first passing portion 105 is an opening formed in the cavity wall of the accommodation cavity 104.

[0288] In some embodiments, the cavity wall of the accommodation cavity 104 where the first connection hole 106 is formed is disposed opposite to the opening of the accommodation cavity, and the cavity wall of the accommodation cavity 104 where the first passing portion 105 is provided intersects with the cavity wall of the accommodation cavity 104 where the first connection hole 106 is formed.

[0289] In some embodiments, the third connecting portion 1115 is located in the first cavity to make the overall structure of the housing 100 compact.

[0290] The cavity wall of the accommodation cavity 104 is located in the first cavity, and the first passing portion 105 is disposed on the cavity wall of the accommodation cavity 104 away from the bottom of the housing 100.

[0291] Such as Fig.36 and Fig.37As shown, in order to facilitate the opening of the accommodation cavity 104 by the cover 700, the cover 700 is provided with an operation part 720. The operation part 720 is arranged on one side of the cover 700 extending along the length direction of the casing 100, and an external force can act on the cover 700 through the operation part 720.

[0292] In some embodiments, the third connection part 1115 is provided with a recessed part, which is located at the opening of the accommodation cavity and is used to increase the size of the opening of the accommodation cavity.

[0293] When the cover 700 closes the accommodation cavity 104, the cover 700 is located within the recessed part.

[0294] When the cover 700 is located within the recessed part, the side of the cover 700 facing away from the accommodation cavity 104 is correspondingly arranged with the outer edge of the recessed part to maintain the aesthetics of the air conditioner indoor unit.

[0295] In some embodiments, the side of the cover 700 facing away from the accommodation cavity 104 is aligned with the outer edge of the recessed part.

[0296] In some embodiments, the recessed part is a counterbore provided at the opening of the accommodation cavity.

[0297] As Fig.58 shown, in order to increase the firmness of the connection between the outer cover 110 and the base 140, the base 140 is provided with a fourth connection part 1413, which is correspondingly arranged with the third connection part 1115. The fourth connection part 1413 is provided with a second connection hole 1414, and one end of the fastener passing through the first connection hole 106 is arranged within the second connection hole 1414, so that the outer cover 110 and the base 140 are connected to each other through the fastener.

[0298] It should be noted that in some embodiments, in order to increase the firmness of the connection between the outer cover 110 and the base 140 through the fastener, the fourth connection part 1413 extends towards the side of the base 140 facing the rear side of the casing 100 to increase the depth of the second connection hole 1414, thereby increasing the depth of the fastener arranged within the second connection hole 1414 to increase the firmness of the connection between the fastener and the base 140.

[0299] The third connection part 1115 restricts the cover 700 through the cantilever 710, which can prevent the cover 700 from being lost due to lack of restraint when opening the accommodation cavity 104 and facilitates the storage of the cover 700.

[0300] In some embodiments, as Figure 6 and Figure 7 shown, the base 140 is provided with a ninth connection part 144, which is arranged at the rear side of the base 140. The outer cover 110 is provided with an eighth connection part 1114. When the outer cover 110 is connected to the base 140, the eighth connection part 1114 is arranged within the ninth connection part 144.

[0301] In some other embodiments, the ninth connecting portion 144 is an opening, and the eighth connecting portion 1114 is a hook. When the outer cover 110 is connected to the base 140, the eighth connecting portion 1114 is first disposed within the ninth connecting portion 144 to preliminarily connect and position the outer cover 110 and the base 140, and then the outer cover 110 and the base 140 are connected by fasteners.

[0302] As Figure 2 、 Figure 4 and Fig.52 shown, the air conditioner indoor unit may include a first air deflector 200. The first air deflector 200 is connected to the housing 100 and opens or closes the first air outlet 102 in an openable and closable manner.

[0303] It should be noted that when the air flow flows from the first air outlet 102 to the room, it is likely to directly blow on the human body, causing discomfort to the user. Therefore, by adjusting the rotation angle of the first air deflector 200, the direction of the air conditioner air output from the first air outlet 102 to the room can be adjusted, and the air flow flowing from the first air outlet 102 to the room can be prevented from directly blowing on the human body.

[0304] The first air deflector 200 rotates around its rotation axis to open or close the first air outlet 102; the rotation axis of the first air deflector 200 is arranged along the length direction of the first air outlet 102.

[0305] It should be noted that in some embodiments, the side of the first air deflector 200 close to the rotation axis of the first air deflector 200 is the root of the air deflector 200.

[0306] The first air deflector 200 is connected with a first motor 240, and the first motor 240 is used to drive the first air deflector 200 to rotate.

[0307] The first motor 240 is connected to one end of the first air deflector 200 along the length direction of the housing 100, and the first motor 240 is disposed on the side of the first air deflector 200 close to the rotation axis of the first air deflector 200.

[0308] It should be noted that the rotation axis of the first motor 240 and the rotation axis of the first air deflector 200 are collinearly arranged.

[0309] Two first motors 240 are provided. The two first motors 240 are installed on the base 140 and are correspondingly disposed at both ends of the first air deflector 200 along the length direction of the housing 100. The two first motors 240 operate synchronously to drive the first air deflector 200 to rotate reliably.

[0310] It should be noted that since the first motors 240 are installed on the base 140 and the two first motors 240 are respectively located at both ends of the first air guide plate 200 along the length direction of the casing 100, therefore, the two first motors 240 can not only provide a large rotational driving force for the first air guide plate 200, but also the motor shafts 512 of the two first motors 240 can support the rotation of the first air guide plate 200, so that the first air guide plate 200 can rotate smoothly.

[0311] As Fig.102 shown, the base 140 is provided with a first fixing portion 1422, and the first fixing portion 1422 is arranged on the side of the base 140 facing away from the heat exchange channel and is close to the edge of the second opening 149.

[0312] The first motor 240 is provided with connecting ear portions, and the connecting ear portions are arranged corresponding to the first fixing portion 1422.

[0313] The first fixing portion 1422 and the connecting ear portions are respectively provided with mounting holes, and the mounting holes of the first fixing portion 1422 are arranged corresponding to the mounting holes of the connecting ear portions. Fasteners such as bolts or screws are simultaneously arranged in the mounting holes of the first fixing portion 1422 and the mounting holes of the connecting ear portions, so that the first motor 240 is mounted on the base 140 through the fasteners.

[0314] In some embodiments, the connecting ear portions are arranged in two to increase the firmness of the installation of the first motor 240. Correspondingly, the first fixing portion 1422 is also arranged in two, and the two first fixing portions 1422 are arranged corresponding to the two connecting ear portions one by one.

[0315] The base 140 is further provided with a second passing portion 1421, and the second passing portion 1421 is located on both side edges of the second opening 149 arranged along the length direction of the casing 100, so that the first motor 240 can pass through the second passing portion 1421 and is rotatably connected to the first air guide plate 200 arranged at the second opening 149.

[0316] In some embodiments, the second passing portion 1421 is an opening formed on the corresponding edges of the base 140 arranged along the length direction of the casing 100.

[0317] The base 140 is provided with a fourth supporting portion 1423, and the fourth supporting portion 1423 is used for supporting the first motor 240 to prevent the first motor 240 from being skewed and affecting the rotation of the first air guide plate 200.

[0318] The fourth supporting portion 1423 is arranged at one end of the base 140 along the length direction of the casing 100 and is located on the side of the base 140 facing away from the heat exchange channel.

[0319] In some embodiments, the fourth supporting portion 1423 is arranged close to the edge of the second opening 149;

[0320] Since the first motor 240 may tilt at any angle, in some embodiments, the fourth support portion 1423 extends as far as possible along the contour of the motor body 511 of the first motor 240 with the first motor 240 as the center, so as to enhance the support effect on the motor body 511 and reduce the skew at any angle.

[0321] When the air-conditioning air is output from the first air outlet 102 to the room, it will contact the windward side of the first air deflector 200. The heat or cold in the air-conditioning air will inevitably be transferred to the first air deflector 200, which easily causes the first air deflector 200 to deform due to heat or cold.

[0322] In this embodiment, by designing the first air deflector 200 as a split structure including a first air plate 210 and a second air plate 220, the second air plate 220 is used to contact the air-conditioning air, so that the second air plate 220 bears the heat or cold of the air-conditioning air. When the second air plate 220 is deformed, only the second air plate 220 is repaired and replaced, thereby reducing the repair and replacement cost of the first air deflector 200.

[0323] Specifically, as Fig.70 shown, the first air plate 210 is located on the leeward side of the first air deflector 200, and the second air plate 220 is located on the windward side of the first air deflector 200.

[0324] The first air plate 210 and the second air plate 220 are detachably connected to each other to facilitate the repair and replacement of the second air plate 220.

[0325] In some embodiments, the side of the second air plate 220 facing away from the first air plate 210 is the windward side of the second air plate 220. The shape of the windward side of the second air plate 220 is adapted to the flow path of the air-conditioning air output from the first air outlet 102 to the room. The second air plate 220 is streamlined to better guide the flow of the air-conditioning air.

[0326] As Fig.68 and Fig.71 shown, the first air plate 210 is provided with a protrusion 211, and the protrusion 211 is provided on one side of the first air plate 210 extending along the length direction of the housing 100.

[0327] As Fig.69 shown, the second air plate 220 is provided with an insertion portion 221, and the insertion portion 221 is provided on one side of the second air plate 220 extending along the length direction of the housing 100.

[0328] The protrusion 211 and the insertion portion 221 are correspondingly arranged so that the first air plate 210 and the second air plate 220 are connected to each other.

[0329] The first air plate 210 is further provided with a first abutting portion 213, and the first abutting portion 213 is provided on one side of the first air plate 210 extending along the length direction of the housing 100.

[0330] The second air deflector 220 is further provided with a second abutting portion 223, and the second abutting portions 223 are respectively arranged on one side of the second air deflector 220 extending along the length direction of the machine housing 100.

[0331] The first abutting portion 213 and the second abutting portion 223 are correspondingly arranged so that the first air deflector 210 and the second air deflector 220 are connected to each other.

[0332] It should be noted that the protrusion 211 and the first abutting portion 213 are correspondingly arranged on both sides of the first air deflector 210 extending along the length direction of the machine housing 100.

[0333] The insertion portion 221 and the second abutting portion 223 are respectively arranged on both sides of the second air deflector 220 extending along the length direction of the machine housing 100.

[0334] When the first air deflector 210 and the second air deflector 220 are connected to each other, first make the first abutting portion 213 and the second abutting portion 223 abut against each other, and then place the protrusion 211 in the insertion portion 221.

[0335] In some other embodiments, the abutting portion between the first abutting portion 213 and the second abutting portion 223 is an inclined plane.

[0336] In some embodiments, the protrusion 211 is located on one side of the first air deflector 210 close to the rotation axis of the air deflector.

[0337] In some embodiments, the protrusion 211 is located on one side of the first air deflector 210 facing the second air deflector 220.

[0338] In some embodiments, the first abutting portion 213 is located on one side of the first air deflector 210 away from the rotation axis of the air deflector.

[0339] In some embodiments, the first abutting portion 213 is located on one side of the first air deflector 210 facing the second air deflector 220.

[0340] In some embodiments, the insertion portion 221 is located on one side of the second air deflector 220 close to the rotation axis of the air deflector.

[0341] In some embodiments, the insertion portion 221 is located on one side of the second air deflector 220 facing the first air deflector 210.

[0342] In some embodiments, the second abutting portion 223 is located on one side of the second air deflector 220 away from the rotation axis of the air deflector.

[0343] In some embodiments, the second abutting portion 223 is located on one side of the second air deflector 220 facing the first air deflector 210.

[0344] In some embodiments, a flange 222 is provided on one side of the second air plate 220 close to the rotation axis of the air guide plate, and the extending portion 221 is opened on the flange 222 .

[0345] In other embodiments, Fig.71 As shown, the first air plate 210 is further provided with a first stop portion 212 , and the first stop portion 212 cooperates with the flange 222 to locate the installation position of the second air plate 220 and the first air plate 210 .

[0346] It should be noted that a plurality of first stop portions 212 are provided, and the plurality of first stop portions 212 are distributed along the length direction of the housing 100 .

[0347] There are also multiple protrusions 211 and multiple insertions 221 , and the multiple protrusions 211 and the multiple insertions 221 are arranged in one-to-one correspondence and distributed along the length direction of the housing 100 .

[0348] By providing a protrusion 211 and a first abutting portion 213 on the first wind plate 210, and providing an extension portion 221 and a second abutting portion 223 on the second wind plate 220, and utilizing the cooperation between the protrusion 211 and the extension portion 221, and the cooperation between the first abutting portion 213 and the second abutting portion 223, not only can the installation and disassembly of the first wind plate 210 and the second wind plate 220 be facilitated, but also the first wind plate 210 and the second wind plate 220 are firmly connected, which facilitates the manufacture of the first wind plate 210 and the second wind plate 220, and by providing a first stop portion 212 on the first wind plate 210, the first stop portion 212 and the flange 222 of the second wind plate 220 are abutted against each other to locate the connection position of the first wind plate 210 and the second wind plate 220.

[0349] Since the first wind plate 210 and the second wind plate 220 are detachably connected and located on the leeward side of the second wind plate 220 , the heat or cold in the air-conditioning wind is easily transferred to the first wind plate 210 through the second wind plate 220 , causing the first wind plate 210 to deform.

[0350] To solve this problem, in this embodiment, a heat-insulating material is provided between the first wind plate 210 and the second wind plate 220 to prevent the temperature of the second wind plate 220 from being transferred to the first wind plate 210 as much as possible, thereby avoiding deformation of the first wind plate 210.

[0351] Specifically, Fig.70 As shown, the first wind plate 210 and the second wind plate 220 define a storage cavity 230, which is located inside the wind guide plate. Insulating material is placed in the storage cavity 230 to prevent the temperature of the second wind plate 220 from being transferred to the first wind plate 210, thereby avoiding deformation of the first wind plate 210.

[0352] It should be noted that the thermal insulation material is usually thermal insulation sponge.

[0353] At present, the length dimensions of some air conditioner indoor units are relatively large, and the length of the first air outlet 102 along the length direction of the casing 100 and the length of the first air deflector 200 are also correspondingly relatively large. Providing support only at both ends of the first air deflector 200 along the length direction of the casing 100 can no longer meet the requirement of the stable rotation of the first air deflector 200. Since the middle part of the first air deflector 200 along the length direction of the casing 100 lacks support, the first air deflector 200 is prone to shaking during the rotation process, which not only affects the air outlet stability, but also generates noise due to the shaking, reducing the user experience.

[0354] Such as Figure 5 、 Fig. 9 and Fig.58 As shown, in this embodiment, a support member 160 is provided at the first air outlet 102, and the air deflector is rotatably connected to the support member 160 so that the support member 160 provides support for the rotation of the air deflector.

[0355] In some embodiments, the support member 160 is provided at the middle part of the first air outlet 102 along the length direction of the casing 100.

[0356] When the support member 160 is provided at the middle part of the first air outlet 102 along the length direction of the casing 100, the supporting force of the support member 160 on the air deflector can be applied to the air deflector more evenly.

[0357] The support member 160 is provided at the second opening 149 and is arranged in a direction intersecting with the extending direction of the first air outlet 102.

[0358] The support member 160 is connected to the outer edges on both sides of the second opening 149 extending along the length direction of the casing 100. Therefore, the support member 160 can also increase the strength of the base 140.

[0359] It should be noted that since the support member 160 is provided at the first air outlet 102, the size of the support member 160 along the length direction of the casing 100 should not be too large, otherwise it will affect the air outlet of the air conditioner. However, if the size is too small, the strength of the support member 160 will be reduced.

[0360] In some embodiments, a second reinforcing rib 161 is provided on one side of the support member 160 along the length direction of the casing 100 to increase the strength of the support member 160.

[0361] Such as Fig. 9 and Fig.33 As shown, the support member 160 is provided with a supporting portion 162, the supporting portion 162 is connected with a rotating member 201, the rotating member 201 is installed on the second air deflector 220, and the supporting portion 162 is rotatably connected with the second air deflector 220 through the rotating member 201 so that the support member 160 can support the rotation of the air deflector.

[0362] As shown Fig.62 in FIG. Fig.62 , the second air deflector 220 is provided with a first adapter portion 206, and the rotating member 201 is connected to the first adapter portion 206 so that the rotating member 201 is connected to the second air deflector 220.

[0363] There are two first adapter portions 206, and the two first adapter portions 206 are distributed along the length direction of the casing 100 and a gap is defined between the two first adapter portions 206 along the length direction of the casing 100.

[0364] The support portion 162 is disposed in the gap so that the first adapter portion 206 can limit the connection position of the support member 160 and the rotating member 201 along the length direction of the casing 100.

[0365] When the support portion 162 is disposed in the gap, the two first adapter portions 206 are correspondingly disposed on both sides of the support member 160 along the length direction of the casing 100.

[0366] The first adapter portion 206 is located on the windward side of the air deflector and is disposed close to the rotation axis of the air deflector.

[0367] As shown Fig.65 and Fig.66 in FIG. Fig.66 , the rotating member 201 includes a rotating portion 2010, and the rotating portion 2010 is rotatably connected to the support portion 162 and the first adapter portion 206 so that the second air deflector 220 is rotatably connected to the support portion 162 through the rotating member 201.

[0368] In some embodiments, as shown Fig.65 and Fig.66 in FIG. Fig.66 , the first adapter portion 206 is provided with a first adapter hole, and the rotating portion 2010 is disposed in the first connection hole 106 so that the rotating member 201 is rotatably connected to the first adapter portion 206.

[0369] The support portion 162 is provided with a second adapter hole, and the rotating portion 2010 is disposed in the second adapter hole so that the rotating member 201 is rotatably connected to the support portion 162.

[0370] In some embodiments, the opening directions of the first adapter hole and the second adapter hole are respectively arranged along the length direction of the casing 100, and the axis of the rotating portion 2010 is arranged along the length direction of the casing 100.

[0371] The rotating member 201 includes a rotating body 2011, and the rotating body 2011 is connected to the second air deflector 220 to increase the connection firmness between the rotating member 201 and the second air deflector 220.

[0372] It should be noted that the rotating portion 2010 is located at one end of the rotating body 2011 along the length direction of the casing 100.

[0373] As shown Fig.64As shown, the second wind plate 220 is provided with a first mounting portion 207, and the first mounting portion 207 is used to fix the rotating body 2011.

[0374] In some embodiments, the first adapter portion 206 is disposed near the side of the mounting portion along the length direction of the housing 100.

[0375] As Fig.66 shown, the rotating body 2011 is provided with a second fixing portion 2012, and the second fixing portion 2012 is located on the side of the rotating body 2011 facing the second wind plate 220.

[0376] The second fixing portion 2012 is correspondingly arranged with the mounting portion, and the second fixing portion 2012 is arranged on the first mounting portion 207 so that the rotating body 2011 is fixedly connected to the second wind plate 220.

[0377] In some embodiments, the first mounting portion 207 is provided with a card slot, and the second fixing portion 2012 is clamped in the card slot so that the rotating member 201 is fixedly connected to the second wind plate 220, which not only increases the firmness of the rotating member 201 mounted on the second wind plate 220, but also facilitates the disassembly of the rotating member 201 from the second wind plate 220.

[0378] When the rotating member 201 needs to be disassembled, the second fixing portion 2012 is disengaged from the first mounting portion 207, and the rotating member 201 can be disassembled from the second wind plate 220.

[0379] In some embodiments, the first mounting portion 207 is disposed in the middle portion of the second wind plate 220 along the length direction of the housing 100, and the first mounting portion 207 is recessed on the windward side of the second wind plate 220, so that when the rotating body 2011 is mounted on the mounting portion, the surface of the rotating body 2011 facing the support member 160 can be generally aligned with the windward side of the second wind plate 220, which not only can maintain the aesthetics of the second wind plate 220, but also can prevent the rotating body 2011 from interfering with the rotation of the second wind plate 220.

[0380] In some embodiments, the first adapter portion 206 protrudes from the windward side of the second wind plate 220.

[0381] In actual production, the first mounting portion 207, the first adapter portion 206 and the second wind plate 220 are integrally injection-molded. Since the first adapter portion 206 is provided with a first adapter hole, during injection molding, if the first adapter hole is designed as a complete circle, in order to facilitate the mold used to form the first adapter hole to be smoothly separated, the second wind plate 220 usually needs to be designed with an avoidance space for easy demolding. The avoidance space is disposed on the windward side of the second wind plate 220, which will affect the aesthetics of the second wind plate 220.

[0382] For the convenience of demolding during injection molding, in this embodiment, as Fig.64As shown, the first adapter part 206 is designed to include two parts, namely a first adapter side wall 2061 and a second adapter side wall 2062. The second connection hole 1414 is defined jointly by the first adapter side wall 2061 and the second adapter side wall 2062.

[0383] The first adapter side wall 2061 and the second adapter side wall 2062 are distributed along the length direction of the housing 100. The second adapter side wall 2062 is located on the side of the first adapter side wall 2061 away from the installation part along the length direction of the housing 100.

[0384] The first adapter side wall 2061 is provided on the windward side of the second wind plate 220 in a protruding manner, and the second adapter side wall 2062 is provided in a recessed manner on the windward side of the second wind plate 220.

[0385] The rotating part 2010 is in contact with both the first adapter side wall 2061 and the second adapter side wall 2062 simultaneously, so that the rotating part 2010 is rotatably connected to the first adapter part 206.

[0386] When the rotating part 2010 is in contact with both the first adapter side wall 2061 and the second adapter side wall 2062 simultaneously, the first adapter side wall 2061 and the second adapter side wall 2062 respectively constrain both sides in the normal direction of the rotating part 2010, so that the rotating part 2010 can be reliably rotatably connected to the first adapter part 206.

[0387] It should be noted that since the first adapter side wall 2061 is provided on the windward side of the second wind plate 220 in a protruding manner, therefore, in order to facilitate the manufacture of the first adapter side wall 2061, as Fig.64 shown, the second wind plate 220 opens a through outlet 202 below the first adapter side wall 2061, so that the mold used for producing the first adapter side wall 2061 can be demolded through the through outlet 202. And the second adapter side wall 2062 is provided in a recessed manner on the windward side of the second wind plate 220. The mold for producing the second adapter side wall 2062 moves away from the second wind plate 220 in a direction perpendicular to the windward side of the second wind plate 220, and then demolding can be carried out.

[0388] It should be noted that since there are two first adapter parts 206, in actual production, for the first adapter part 206 close to the installation part, the mold that can be used to form the first adapter hole can move in the direction of the first adapter part 206 away from the installation part and be demolded from the gap jointly formed by the two first adapter parts 206. Therefore, the first adapter part 206 close to the first installation part 207 can be designed as a complete circle without being designed as a split type. This belongs to the common knowledge in the art and will not be elaborated here.

[0389] In some embodiments, the motor shaft of the first motor 240 is also connected with a rotating part 201. The motor shaft of the first motor 240 is used for the rotatable connection of the first air deflector 200 through the rotating part 201.

[0390] When the motor shaft of the first motor 240 is connected to the second air deflector 220 through the rotating member 201, in order to facilitate the connection between the motor shaft 512 and the rotating member 201, the rotating portion 2010 is provided with a connection cavity, and the motor shaft of the first motor 240 is disposed in the connection cavity so that the motor shaft of the first motor 240 is connected to the rotating member 201.

[0391] The connection cavity is formed in the rotating portion 2010, and the opening of the connection cavity is disposed at one end of the rotating portion 2010 away from the rotating body 2011.

[0392] As Fig.67 shown, one end of the second air deflector 220 along the length direction of the housing 100 is provided with a second adapter portion 203 and a third adapter portion 204. The motor shafts of the two first motors 240 are correspondingly connected to the second adapter portion 203 and the third adapter portion 204 through the rotating member 201, so that the second adapter portion 203 and the third adapter portion 204 apply constraints to the rotating portions 2010 of the corresponding rotating members 201, and the firmness of the connection between the rotating member 201 and the second air deflector 220 is increased.

[0393] As Fig.72 shown, in some embodiments, the support member 160 is provided on the surface of the raised base 140. On the one hand, it can facilitate the connection between the support member 160 and the first air deflector 200, and on the other hand, it can increase the firmness of the connection between the support member 160 and the base 140.

[0394] It should be noted that a first protrusion 163 is defined at the lower end of the support member 160, and the first protrusion 163 is located on the side of the support member 160 away from the inside of the housing 100.

[0395] When the outer cover 110 is connected to the base 140, the support member 160 may interfere with the connection between the base 140 and the outer cover 110.

[0396] As Fig.60 shown, the outer cover 110 is provided with an avoidance opening 1119, and the avoidance opening 1119 is correspondingly arranged with the first protrusion 163 to prevent the first protrusion 163 from interfering with the connection between the base 140 and the outer cover 110.

[0397] When the outer cover 110 is connected to the base 140, the first protrusion 163 is disposed in the avoidance opening 1119. Therefore, when connecting the outer cover 110 and the base 140, by disposing the first protrusion 163 in the avoidance opening 1119, the connection position between the outer cover 110 and the base 140 can be positioned.

[0398] In some embodiments, the avoidance opening 1119 is a notch formed in the outer cover 110, and the first protrusion 163 is disposed in the notch to position the connection position between the base 140 and the outer cover 110.

[0399] In some embodiments, a third reinforcing rib 1116 is provided on one side of the outer cover 110 facing the base 140. The third reinforcing rib 1116 is disposed on the outer periphery of the avoidance opening 1119 and is used to increase the strength of the avoidance opening 1119.

[0400] In some embodiments, the first convex portion 163 extends to the outer edge of one side of the base 140 extending along the length direction of the casing 100. Therefore, the first convex portion 163 also increases the connection area between the support member 160 and the base 140, thereby increasing the connection strength between the support member 160 and the base 140.

[0401] By providing the support member 160 at the second opening 149, the deformation of the second opening 149 is prevented, and the strength of the base 140 is increased; and the support member 160 is used to support the rotation of the air deflector, so as to increase the smoothness of the operation of the air deflector and reduce the noise generated by the rotation of the air deflector; and the strength of the base 140 can be increased without affecting the air outlet effect of the air conditioner, and the smoothness of the rotation of the air deflector can be improved.

[0402] The two ends of the first air deflector 200 along the length direction of the casing 100 are correspondingly arranged with the two side edges of the first air outlet 102 along the length direction, and there is a gap between the end of the first air deflector 200 along the length direction of the casing 100 and the corresponding edge of the first air outlet 102 to ensure that the first air deflector 200 can rotate reliably. The sizes of the two gaps between the two ends of the first air deflector 200 along the length direction and the two side edges of the first air outlet 102 along the length direction of the casing 100 are generally approximately the same to ensure the aesthetics of the air conditioner indoor unit.

[0403] Since the first air deflector 200 will inevitably shift along the length direction of the casing 100 during the rotation process, it will not only affect the operation of the first air deflector 200, but also when the first air deflector 200 closes the first air outlet 102, the sizes of the two gaps along the length direction of the casing 100 are different, affecting the aesthetics of the air conditioner indoor unit.

[0404] In this embodiment, as Fig.62 、 Fig.64 and Fig.73 shown, a first restraint portion 205 is provided at the root of the first air deflector 200. The first restraint portion 205 is correspondingly arranged with the support member 160. The support member 160 is used to adjust the connection position of the first air deflector 200 along the length direction of the casing 100 with the support member 160, so as to adjust the setting position of the first air deflector 200 along the length direction of the casing 100 to prevent the first air deflector 200 from shifting along the length direction of the casing 100.

[0405] When the first air deflector 200 rotates until the first constraint portion 205 contacts the support member 160, the support member 160 adjusts the connection position of the first air deflector 200 along the length direction of the housing 100 with respect to the support member 160 through the first constraint portion 205.

[0406] In some embodiments, when the first air deflector 200 rotates to open the first air outlet 102 at the maximum angle, the first constraint portion 205 contacts the bottom of the support member 160.

[0407] The first constraint portion 205 is located on a side of the first air deflector 200 close to the rotation axis of the first air deflector 200, so that when the first air deflector 200 rotates, the first constraint portion 205 can contact the support member 160.

[0408] The first constraint portion 205 is arranged between two first adapter portions 206 along the length direction of the housing 100.

[0409] In some embodiments, the support member 160 is provided with a first mating portion 164. The first mating portion 164 is located below the support portion 162. The first mating portion 164 and the first constraint portion 205 are correspondingly arranged and cooperate with each other. The position of the first mating portion 164 is constrained by the first constraint portion 205 to adjust the connection position of the first air deflector 200 along the length direction of the housing 100 with respect to the support member 160.

[0410] The first constraint portion 205 is provided with a first mating surface, and the first mating surface is located on one of the inner walls of the first constraint portion 205 arranged along the length direction of the housing 100; the first mating portion 164 is provided with a second mating surface, and the second mating surface is located on one of the side wall surfaces of the first mating portion 164 arranged along the length direction of the housing 100. The second mating surface and the first mating surface are correspondingly arranged.

[0411] There are two first mating surfaces, and the two first mating surfaces are correspondingly arranged on the two inner walls of the first constraint portion 205 arranged along the length direction of the housing 100; the two first mating surfaces jointly define a concave portion, and the first mating portion 164 is arranged in the concave portion and is adapted to the concave portion.

[0412] There are also two second mating surfaces, and the two second mating surfaces are correspondingly arranged on the two side wall surfaces of the first mating portion 164 arranged along the length direction of the housing 100. The two first mating surfaces and the two second mating surfaces are arranged in one-to-one correspondence.

[0413] It should be noted that there is usually a certain gap between the first mating surface and the second mating surface to ensure reliable rotation of the first air deflector 200. However, if there is a gap between the first mating surface and the second mating surface, it is likely to reduce the positioning accuracy of the first air deflector 200.

[0414] Such as Fig.73As shown, in this embodiment, the first mating surface and the second mating surface are set as inclined surfaces, so that when the first air guide plate 200 moves along the length direction of the housing 100, the first mating surface and the second mating surface can contact each other without affecting the rotation of the first air guide plate 200.

[0415] The distance between the two first mating surfaces along the length direction of the housing 100 increases from the end where the first constraint portion 205 is connected to the first air guide plate 200 toward the end where the first constraint portion 205 is away from the first air guide plate 200 .

[0416] The distance between the two second mating surfaces decreases from the top of the support member 160 toward the bottom of the support member 160 .

[0417] The two first matching surfaces jointly define the recess to form a V-shaped structure.

[0418] The two second mating surfaces also define the first mating portion 164 to form a V-shaped structure.

[0419] The minimum dimension between the two first mating surfaces along the length direction of the casing 100 is greater than the minimum dimension between the two second mating surfaces along the length direction of the casing 100, and the minimum dimension between the two first mating surfaces along the length direction of the casing 100 is smaller than the maximum dimension between the two second mating surfaces along the length direction of the casing 100.

[0420] Since the bottom of the support member 160 is arranged in the gap formed by the two first adapter portions 206, the maximum distance between the two first mating surfaces along the length direction of the housing 100 is less than or equal to the spacing between the two first adapter portions 206 along the length direction of the housing 100, so that the first mating surfaces can contact each other with the support member 160.

[0421] The maximum distance between the two second mating surfaces along the length direction of the housing 100 is less than or equal to the spacing between the two first transition portions 206 along the length direction of the housing 100 , so that the support member 160 can be disposed in the gap formed by the two first transition portions 206 .

[0422] The working principle of the above-mentioned air-conditioning indoor unit is: when the first air guide plate 200 is to close the first air outlet 102, the driving motor drives the first air guide plate 200 to rotate until the first constraint part 205 and the support member 160 are in contact with each other, and the two first mating surfaces of the first constraint part 205 interact with the two second mating surfaces of the first mating part 164 to adjust the position of the first air guide plate 200 along the length direction of the casing 100, so that when the first air guide plate 200 closes the first air outlet 102, the gaps between the two ends of the first air guide plate 200 relatively set along the length direction of the casing 100 and the two side edges of the first air outlet 102 relatively set along the length direction of the casing 100 can be roughly symmetrically arranged, thereby ensuring the aesthetics of the air-conditioning indoor unit.

[0423] By providing a first restraint portion 205 on the first air deflector 200 and a first mating portion 164 on the support member 160, the above-described air conditioner indoor unit utilizes the mutual cooperation between the first restraint portion 205 and the first mating portion 164 to adjust the connection position of the first air deflector 200 along the length direction of the casing 100 with respect to the support member 160, thereby preventing the first air deflector 200 from shifting along the length direction of the casing 100 and ensuring the aesthetic appearance of the air conditioner indoor unit when the first air deflector 200 closes the first air outlet 102.

[0424] In the above-described air conditioner indoor unit, the support member 160 can not only support the rotation of the first air deflector 200, increasing the smoothness of the rotation of the first air deflector 200, but also adjust the setting position of the first air deflector 200 along the length direction of the casing 100, ensuring the reliability of the operation of the first air deflector 200 and the aesthetic appearance of the air conditioner indoor unit when the first air deflector 200 closes the first air outlet 102.

[0425] As Figure 4 shown, the air conditioner indoor unit may include a second air deflector 600. The second air deflector 600 is used to guide the flow direction of the air conditioner air or change the flow direction of the air conditioner air, and the second air deflector 600 is also used to adjust the air volume of the air conditioner air. The second air deflector 600 is rotatably provided at the first air outlet 102. The second air deflector 600 is located on the side of the first air deflector 200 facing the interior of the casing 100, and the second air deflector 600 is located between the first air deflector 200 and the heat exchange fan.

[0426] It should be noted that the distance between the second air deflector 600 and the heat exchange fan is less than the distance between the first air deflector 200 and the heat exchange fan.

[0427] Through the operation of the heat exchange fan, the air conditioner air that has exchanged heat with the heat exchanger 300 is led to the second air deflector 600. The second air deflector 600 guides part of the air conditioner air to the first air outlet 102, and the second air deflector 600 guides another part of the air conditioner air to the first air deflector 200 and the air conditioner air is guided by the first air deflector 200 to the first air outlet 102.

[0428] In some embodiments, the second air deflector 600 prevents the air conditioner air from directly blowing on the human body by guiding the air conditioner air to blow on the first air deflector 200 and utilizing the first air deflector 200 to guide the outlet direction of the air conditioner air.

[0429] In some embodiments, the second air deflector 600 can also increase the air outlet resistance of the air conditioner air to reduce the air volume and the air outlet noise of the air conditioner air.

[0430] The second air deflector 600 rotates about its rotation axis to guide the flow of the air conditioner air or change the flow direction of the air conditioner air. The rotation axis of the second air deflector 600 is provided along the length direction of the first air outlet 102.

[0431] The second air deflector 600 is connected to a second motor 610 for driving the second air deflector 600 to move; the second motor 610 and the first motor 240 operate independently of each other so that the first air deflector 200 and the second air deflector 600 move independently of each other.

[0432] It should be noted that the second air deflector 600 is usually connected to a second motor 610, and the second motor 610 is connected to one end of the second air deflector 600 along the length direction of the casing 100. The other end of the second air deflector 600 along the length direction of the casing 100 is rotatably connected to the base 140 to support the rotation of the second air deflector 600.

[0433] When the length dimension of the air conditioner indoor unit is large and the dimension of the first air outlet 102 along the length direction of the casing 100 is large, the length dimension of the second air deflector 600 is also large. It is difficult to ensure the smooth operation of the second air deflector 600 only by restricting the two ends of the second air deflector 600 along the length direction of the casing 100.

[0434] As Fig.91 shown, the base 140 is provided with a fifth connecting portion 1419. The fifth connecting portion 1419 is located at the upper edge of the second opening 149 along the length direction of the casing 100. The fifth connecting portion 1419 is connected to a rotating member 620, and the rotating member 620 is connected to the second air deflector 600 so that the second air deflector 600 is rotatably connected to the fifth connecting portion 1419 through the rotating member 620, thereby enabling the fifth connecting portion 1419 to provide support for the rotation of the second air deflector 600.

[0435] It should be noted that the rotating member 620 is a conventional technical means in the art and will not be elaborated here.

[0436] In some embodiments, as Fig.91 and Fig.98 shown, the second air deflector 600 is provided with an avoidance portion 630. The avoidance portion 630 is located on one side of the second air deflector 600 close to the rotation axis of the second air deflector 600. The avoidance portion 630 is arranged corresponding to the fifth connecting portion 1419 to prevent the second air deflector 600 from interfering with the connection between the rotating member 620 and the fifth connecting portion 1419.

[0437] One end of the second air deflector 600 along the length direction of the casing 100 is connected to the second motor 610. In addition to driving the second air deflector 600 to rotate, the second motor 610 also provides support for the rotation of the second air deflector 600. The other end of the second air deflector 600 along the length direction of the casing 100 is rotatably connected to the base 140 to enable the second air deflector 600 to rotate smoothly.

[0438] The second motor 610 is also provided with a connecting ear, and the base 140 is provided with a third fixing portion 1424. The third fixing portion 1424 is arranged corresponding to the connecting ear of the second motor 610. The third fixing portion 1424 and the connecting ear of the second motor 610 are respectively provided with connecting holes, and the connecting holes of the third fixing portion 1424 are arranged corresponding to the connecting holes of the connecting ears of the second motor 610. Fasteners such as bolts or screws are simultaneously arranged in the connecting holes of the third fixing portion 1424 and the connecting holes of the connecting ears of the second motor 610, so that the second motor 610 can be installed on the base 140.

[0439] In some embodiments, the second motor 610 is provided with two connecting ears to increase the firmness of the installation of the second motor 610. Accordingly, the third fixing portions 1424 are also provided with two, and the two third fixing portions 1424 are provided in one-to-one correspondence with the two connecting ears.

[0440] like Fig.101 As shown, the base 140 is also provided with a third outlet portion 1420, which is located at the two side edges of the second opening 149 arranged along the length direction of the casing 100, so that the second motor 610 can pass through the third outlet portion 1420 and be rotatably connected to the second air guide plate 600 arranged at the second opening 149.

[0441] The base 140 is provided with a fifth support portion 1425, which is provided on a side of the base 140 away from the heat exchange channel. The fifth support portion 1425 is used to provide support for the second motor 610 to prevent the second motor 610 from tilting when loaded, causing the position of the second air guide plate 600 to deviate from the position of the second air guide plate 600 when it is working normally, thereby affecting the rotation of the second air guide plate 600.

[0442] In some embodiments, the third penetration portion 1420 is a through opening opened in the base 140 , and the third penetration portion 1420 and the fifth support portion 1425 are disposed correspondingly.

[0443] Since the second motor 610 may tilt at any angle, in some embodiments, the fifth support portion 1425 is centered on the second motor 610 and extends as far as possible along the contour of the motor body 511 of the second motor 610 to enhance the supporting effect on the motor body 511 and reduce any angle of skewness.

[0444] In practical applications, the second air guide plate 600 has an initial position. When the air conditioner indoor unit is turned off, the second air guide plate 600 usually returns to the initial position, and the initial position of the second air guide plate 600 is also a reference position for the movement of the second air guide plate 600. It should be noted that when the second air guide plate 600 is set at the initial position, the air conditioner indoor unit has a better aesthetic appearance.

[0445] Since the second air deflector 600 is usually only connected to one second motor 610, both ends of the second air deflector 600 along the length direction of the housing 100 are prone to deviation when the second air deflector 600 rotates due to uneven force, resulting in the second air deflector 600 being unable to return to the initial position, thereby causing the movement reference position of the second air deflector 600 to deviate. This will not only affect the air guiding effect of the second air deflector 600, but also affect the aesthetics of the air conditioner indoor unit.

[0446] In this embodiment, a calibration part 1418 is provided on the base 140, and the calibration part 1418 is used to contact the second air deflector 600 to correct the position of the second air deflector 600.

[0447] Specifically, as Fig.96 shown, the calibration part 1418 is located at the upper edge of the second opening 149. When the second motor 610 drives the second air deflector 600 to rotate towards the direction close to the calibration part 1418, the calibration part 1418 contacts the side of the second air deflector 600 facing the calibration part 1418, and the calibration part 1418 and the second air deflector 600 interact with each other to calibrate or reset the position of the second air deflector 600.

[0448] It should be noted that the end of the second air deflector 600 connected to the second motor 610 is the active end, and the end of the second air deflector 600 far from the second motor 610 is the driven end. The active end drives the driven end to rotate. Therefore, in this embodiment, the calibration part 1418 is arranged on the side of the base 140 close to the installed second motor 610 to enhance the calibration effect of the calibration part 1418 on the second air deflector 600.

[0449] In some embodiments, as Fig.99 shown, a second matching part 640 is provided on the side of the second air deflector 600 facing the calibration part 1418. The second matching part 640 and the calibration part 1418 cooperate with each other to enable the calibration part 1418 to correct and reset the second air deflector 600.

[0450] In other embodiments, the second matching part 640 is provided with a third matching surface, and the side of the calibration part 1418 facing the second air deflector 600 is provided with a fourth matching surface. The fourth matching surface contacts the third matching surface to correct the position of the second air deflector 600.

[0451] It should be noted that when the second air deflector 600 is in the initial position, the third matching surface and the fourth matching surface contact each other.

[0452] In some embodiments, the second air deflector 600 can hide the calibration part 1418 to avoid the calibration part 1418 affecting the aesthetics of the air conditioner indoor unit.

[0453] In some embodiments, the calibration part 1418 protrudes from the surface of the base 140. The calibration part 1418 and the base 140 are integrally injection-molded, which not only facilitates the setting of the calibration part 1418, but also has a high connection strength between the calibration part 1418 and the base 140.

[0454] Through the operation of the heat exchange fan, indoor air is introduced into the heat exchange channel from the first air inlet 101, contacts the heat exchanger 300 and exchanges heat to form air-conditioning air. A part of the air-conditioning air is output to the room after being guided by the second air deflector 600 through the first air outlet 102, and another part of the air-conditioning air flows to the first air deflector 200 after being guided by the second air deflector 600 through the first air outlet 102, and is output to the room after the action of the first air deflector 200.

[0455] When the indoor unit of the air conditioner is turned off, the second motor 610 drives the second air deflector 600 to rotate towards the direction close to the calibration part 1418. When the second matching part 640 and the calibration part 1418 are in mutual extrusion contact, the calibration part 1418 calibrates and resets the position of the second air deflector 600. After the second air deflector 600 is calibrated, the second motor 610 drives the second air deflector 600 to move to the initial position.

[0456] It should be noted that in actual application, when the indoor unit of the air conditioner is turned off, the second air deflector 600 needs to first rotate to the position where the second matching part 640 and the calibration part 1418 are in mutual contact, and the calibration part 1418 calibrates the position of the second air deflector 600 and then returns to the initial position of the second air deflector 600. This belongs to the well-known common sense technology in this field and will not be elaborated here.

[0457] The above-mentioned indoor unit of the air conditioner can calibrate the position of the second air deflector 600, with good calibration effect, high working reliability of the second air deflector 600, firm installation of the second air deflector 600, high running stability, good air guiding effect, and firm installation of the second motor 610 that drives the second air deflector 600 to move.

[0458] In the above-mentioned indoor unit of the air conditioner, the calibration part 1418 is easy to manufacture, is conducive to mold release and does not affect the mold structure.

[0459] The heat exchanger 300 is installed in the casing 100 and is located in the heat exchange channel. The air in the heat exchange channel contacts the heat exchanger 300 and is heated or cooled by the heat exchanger 300 to form air-conditioning air to meet the cooling or heating needs of users.

[0460] It should be noted that the heat exchanger 300 is arranged close to the first air inlet 101. It should also be noted that the air-conditioning air can be cold air, hot air, or even normal-temperature air.

[0461] Such as Fig.54As shown, the base 140 is provided with a sixth support portion 1415. The sixth support portion 1415 is in contact with one side of the heat exchanger 300 facing the heat exchange fan to support the heat exchanger 300.

[0462] It should be noted that the sixth support portion 1415 extends along the length direction of the housing 100 to enhance the supporting effect of the sixth support portion 1415 on the heat exchanger 300.

[0463] As Fig.55 shown, the air conditioner indoor unit includes an end plate 340. The end plate 340 is connected to the base 140 to fix the heat exchanger 300.

[0464] The end plate 340 is connected to one end of the heat exchanger 300 along the length direction of the housing 100.

[0465] It should be noted that a retaining wall 1417 is provided on one side of the base 140 facing the rear side of the housing 100. The retaining wall 1417 is used to close the opening of the first cavity, and one end of the end plate 340 facing the rear side of the housing 100 abuts against the retaining wall 1417.

[0466] As Fig.55 shown, the end plate 340 is provided with a seventh support portion 342. The seventh support portion 342 is disposed on one side of the end plate 340 facing the heat exchanger 300. The seventh support portion 342 is correspondingly arranged with one side of the heat exchanger 300 facing the heat exchange fan to support the heat exchanger 300 and enhance the reliability of the heat exchanger 300 disposed on the base 140.

[0467] To enhance the firmness of the installation of the heat exchanger 300, the end plate 340 is provided with a third limiting portion 341. The third limiting portion 341 is located on the front side and / or the rear side of the heat exchanger 300 and is used to limit the position of the heat exchanger 300 and prevent the heat exchanger 300 from moving along the thickness direction of the housing 100.

[0468] In some embodiments, the third limiting portion 341 is disposed on one side of the heat exchanger 300 facing the front side of the housing 100 and / or one side of the heat exchanger 300 facing the rear side of the housing 100, and the third limiting portion 341 is in contact with the heat exchanger 300 or there is a gap between the two to limit the heat exchanger 300 from moving along the thickness direction of the housing 100.

[0469] Since the bottom of the heat exchanger 300 is in contact with the sixth support portion 1415 while the top of the heat exchanger 300 lacks restraint, therefore, to increase the restraint on the top of the heat exchanger 300, the third limiting portion 341 is disposed close to the top of the end plate 340 so that the third limiting portion 341 also restrains the part of the heat exchanger 300 close to the top of the housing 100.

[0470] By providing a third limiting portion 341 on the end plate 340, the third limiting portion 341 is used to limit the top of the heat exchanger 300 and the front-back direction of the heat exchanger 300, preventing the heat exchanger 300 from moving.

[0471] As Fig.56 shown, in order to increase the firmness of the connection between the end plate 340 and the base 140, the outer cover 110 is provided with a fourth limiting portion 1118. The fourth limiting portion 1118 is located in the outer cavity and contacts the end plate 340 to limit and restrain the end plate 340.

[0472] Since one end of the end plate 340 facing the rear side of the casing 100 abuts against the retaining wall 1417, in some embodiments, the fourth limiting portion 1118 is respectively on one side of the end plate 340 facing the front side of the casing 100 to prevent the end plate 340 from moving in the thickness direction of the casing 100.

[0473] In some other embodiments, the fourth limiting portion 1118 also contacts the top of the end plate 340 to prevent the end plate 340 from moving in the height direction of the casing 100.

[0474] By providing the fourth limiting portion 1118 on the outer cover 110, the fourth limiting portion 1118 is used to limit the front-back sides and the top of the end plate 340 to prevent the end plate 340 from moving and ensure the firmness of the installation of the heat exchanger 300.

[0475] As Fig.12 shown, the heat exchanger 300 includes a first section 310. The first section 310 extends along the length direction of the casing 100 and is disposed near the front side of the casing 100.

[0476] The heat exchanger 300 includes a second section 320. The second section 320 extends along the length direction of the casing 100 and is disposed near the first air inlet 101.

[0477] The heat exchanger 300 includes a third section 330. The third section 330 extends along the length direction of the casing 100 and is disposed near the rear side of the casing 100.

[0478] It should be noted that the first section 310 and the third section 330 are generally disposed along the height direction of the casing 100.

[0479] The second section 320 is respectively connected to the top of the first section 310 and the top of the third section 330, so that the heat exchanger 300 is generally in a semi-surrounding structure located on top of the heat exchange fan.

[0480] The bottom of the first section 310 and the bottom of the third section 330 are respectively disposed close to the base 140. The base 140 is provided with two sixth support portions 1415. The two sixth support portions 1415 extend along the length direction of the casing 100. The two sixth support portions 1415 are correspondingly in contact with the first section 310 and the third section 330, so that the two sixth support portions 1415 correspondingly provide support force for the first section 310 and the third section 330.

[0481] By providing the sixth support portion 1415 on the base 140 and using the sixth support portion 1415 to support the heat exchanger 300, the firmness of the installation of the heat exchanger 300 is increased.

[0482] Since the third limiting portion 341 is also provided in this embodiment to fix the heat exchanger 300, and the fourth limiting portion 1118 is also provided to fix the end plate 340, in some embodiments, the length dimension of the sixth support portion 1415 in contact with the third section 330 is reduced and is in contact with the middle portion of the third section 330 to save materials.

[0483] In this embodiment, the heat exchanger 300 is firmly installed and has a good protection effect on the heat exchanger 300.

[0484] When air exchanges heat through the heat exchanger 300, condensed water is likely to be generated. The condensed water generated by the air heat exchange usually remains on the surface of the heat exchanger 300. Among them, the condensed water on the surface of the first section 310 drips along its wall surface under the action of gravity, and the condensed water on the surface of the third section 330 drips along its wall surface under the action of gravity. The height of one end of the second section 320 connected to the first section 310 is less than the height of one end of the second section 320 connected to the third section 330, so that the condensed water on the surface of the second section 320 can flow along the wall surface of the second section 320 to the first section 310 under the action of gravity and then drip along the wall surface of the first section 310. This belongs to the well-known common sense technology in the art and will not be elaborated here.

[0485] As Fig.12 and Fig.13 shown, the base 140 is provided with a water receiving portion 1416. The water receiving portion 1416 is disposed on one side of the base 140 facing the front side of the casing 100 and on one side of the base 140 facing the rear side of the casing 100. The water receiving portion 1416 extends along the length direction of the casing 100.

[0486] Among them, the water receiving portion 1416 disposed on the front side of the base 140 facing the casing 100 is correspondingly arranged with the first section 310 and is located below the first section 310.

[0487] The water receiving portion 1416 disposed on the rear side of the base 140 facing the casing 100 is correspondingly arranged with the third section 330 and is located below the third section 330.

[0488] The condensed water generated by the heat exchange of the heat exchanger 300 drips onto the water receiving part 1416 under the action of gravity. The water receiving part 1416 is connected with a drain pipe, so that the condensed water generated by the heat exchange of the heat exchanger 300 is discharged from the air conditioner indoor unit through the drain pipe.

[0489] Since the heat exchanger 300 is arranged in the first cavity, the side of the first section 310 away from the heat exchange fan is arranged close to the side of the outer cover 110 facing the rear side of the machine shell 100. When the heat exchanger 300 exchanges heat with air, condensed water may also be generated on the side of the outer cover 110 facing the rear side of the machine shell 100. Therefore, in this embodiment, a diversion part 1117 is arranged on the side of the outer cover 110 facing the rear side of the machine shell 100. The diversion part 1117 is correspondingly arranged with the water receiving part 1416 arranged on the base 140 facing the front side of the machine shell 100, so that the condensed water generated on the side of the outer cover 110 facing the rear side of the machine shell 100 gathers at the diversion part 1117 and drips onto the water receiving part 1416 along the diversion part 1117.

[0490] Specifically, the diversion part 1117 is located above the water receiving part 1416 arranged on the base 140 facing the front side of the machine shell 100. The diversion part 1117 is arranged to incline downward from the front side of the machine shell 100 towards the rear side of the machine shell 100, so that the condensed water dripping onto the diversion part 1117 drips onto the water receiving part 1416 under the action of gravity along the diversion part 1117.

[0491] It should be noted that the side of the third section 330 away from the heat exchange fan faces the baffle 1417, and the water receiving part 1416 arranged on the base 140 facing the rear side of the machine shell 100 is located below the baffle 1417. Therefore, the condensed water generated by the baffle 1417 will drip onto the water receiving part 1416 arranged on the base 140 facing the rear side of the machine shell 100 along the baffle 1417. This belongs to the well-known common sense technology in the field and will not be elaborated here.

[0492] By arranging the diversion part 1117 on the inner wall of the outer cover 110 close to the first section 310, and the diversion part 1117 is correspondingly arranged with the water receiving part 1416 arranged on the base 140 facing the front side of the machine shell 100, so that the condensed water generated on the inner wall of the outer cover 110 close to the first section 310 can drip onto the water receiving part 1416 from the diversion part 1117.

[0493] By arranging the diversion part 1117 to be inclined, and arranging the diversion part 1117 above the water receiving part 1416 and the side with a lower height of the diversion part 1117 corresponding to the water receiving part 1416, it is convenient for the condensed water to drip onto the water receiving part 1416 under the action of gravity.

[0494] The heat exchange fan is installed on the machine shell 100 and is located in the heat exchange channel, and the heat exchange fan is located on the side of the heat exchanger 300 away from the first air inlet 101. The axial direction of the heat exchange fan extends along the length direction of the machine shell 100.

[0495] Through the operation of the heat exchange fan, indoor air is introduced into the heat exchange channel through the first air inlet 101. After being heat exchanged by the heat exchanger 300 to form air-conditioning wind, the air-conditioning wind flows into the room through the first air outlet 102.

[0496] It should be noted that the heat exchange fan is a cross-flow fan.

[0497] The indoor unit of the air conditioner may include a display component, and the display component includes a display board 800. The display board 800 is used to display information related to the operation of the indoor unit of the air conditioner; the display board 800 is used to control relevant information during the operation of the indoor unit of the air conditioner, such as the operation mode of the indoor unit of the air conditioner and relevant information such as the set temperature and wind speed.

[0498] In some embodiments, the display board 800 is also used to display different colors to enhance the aesthetics of the indoor unit of the air conditioner.

[0499] The display component may include a display box 400. The display box 400 is disposed near the front side of the housing 100, and the display box 400 is used to mount the display board 800.

[0500] It should be noted that the display content of the display board 800 and the display principle of the display board 800 belong to the well-known common sense technology in the art, and will not be elaborated here.

[0501] Since the outer cover 110 is in a frame structure, during the drop test or transportation of the indoor unit of the air conditioner, the display box 400 is likely to pass through the outer cover 110 and contact the side of the heat exchanger 300 facing the front side of the housing 100, resulting in damage to the heat exchanger 300. Therefore, in this embodiment, as Figure 2 shown, an isolation part 111 is provided on the outer cover 110. By arranging the isolation part 111 between the display box 400 and the heat exchanger 300, the damage of the display box 400 to the heat exchanger 300 is reduced.

[0502] Specifically, the isolation part 111 is provided on the outer cover 110 and is located on the side of the outer cover 110 facing the front side of the housing 100. The isolation part 111 is located between the display box 400 and the heat exchanger 300.

[0503] When the display box 400 is affected by an external force and approaches the heat exchanger 300, the display box 400 first contacts the isolation part 111, and the isolation part 111 will generate a reaction force on the display box 400 to prevent the display box 400 from continuing to approach the heat exchanger 300.

[0504] When the reaction force of the isolation part 111 on the display box 400 is less than the external force received by the display box 400, the display box 400 still continues to move towards the heat exchanger 300. The display box 400 will cause the isolation part 111 to contact the heat exchanger 300. At this time, a part of the external force acting on the display box 400 is offset by the reaction force provided by the isolation part 111. Therefore, the damage to the heat exchanger 300 is relatively small. This belongs to the well-known common sense technology in this field and will not be elaborated here.

[0505] It should be noted that the heat exchanger 300 is usually selected as a fin heat exchanger 300. When the heat exchanger 300 collides or interacts with other components, the fins are prone to lodging, reducing the heat exchange efficiency of the heat exchanger 300.

[0506] By providing the isolation part 111 on the outer cover 110, the isolation part 111 is used to prevent the display box 400 from directly contacting the heat exchanger 300, so as to prevent the display box 400 from damaging the heat exchanger 300 during the drop test or transportation of the air conditioner indoor unit.

[0507] The air conditioner indoor unit may include an electric control box. The electric control box is installed on the housing 100. A circuit board is provided inside the electric control box, and the circuit board is electrically connected to the motor through a circuit.

[0508] The display board 800 is electrically connected to the circuit board in the electric control box. The circuit board is used to control the display information of the display board 800, such as the operation mode of the air conditioner indoor unit and related information such as the set temperature and wind speed.

[0509] The display board 800 is usually arranged close to the electric control box to facilitate the circuit wiring connection between the display board 800 and the circuit board.

[0510] It should also be noted that in the prior art, the electric control box is usually arranged at one end in the length direction of the housing 100. Therefore, the display board 800 is usually also correspondingly arranged at one end in the length direction of the housing 100, and the display board 800 is usually arranged on the front side of the housing 100 to facilitate the user to obtain the display information of the display board 800.

[0511] As Fig.42 shown, in order to prevent the housing 100 from affecting the user's acquisition of the display content, the front panel 150 is provided with a light-transmitting part 152. The light-transmitting part 152 is arranged corresponding to the display board 800, so that the display content of the display board 800 can pass through the light-transmitting part 152 and be obtained by the user, thereby preventing the housing 100 from blocking the display board 800 and avoiding the housing 100 from affecting the display effect of the display board 800.

[0512] In some embodiments, the light-transmitting part 152 is a through-hole, and the opening direction of the through-hole is arranged along the thickness direction of the housing 100.

[0513] As Fig.40As shown, in order to facilitate the installation of the display panel 800, in this embodiment, a mounting member 900 is provided. Generally, the display panel 800 is mounted on the mounting member 900, and then the mounting member 900 is detachably connected to the front panel 150, so that the display panel 800 is mounted on the front panel 150.

[0514] As Fig.47 shown, the mounting member 900 is provided with a third mounting portion 960, and the third mounting portion 960 is correspondingly arranged with the light-transmitting portion 152. The display panel 800 is arranged on the third mounting portion 960, so that the display content of the display panel 800 can be obtained by the user through the light-transmitting portion 152.

[0515] In some embodiments, the third mounting portion 960 is a through-hole opened on the mounting member 900, and the opening direction of the through-hole is arranged along the thickness direction of the housing 100.

[0516] In some embodiments, the display panel 800 is generally in a circular structure, and the mounting member 900, the light-transmitting portion 152 and the third mounting portion 960 are also correspondingly generally in a circular structure.

[0517] It should be noted that one side of the mounting member 900 along the thickness direction of the housing 100 is arranged on the front side of the front panel 150, and the other side of the mounting member 900 along the thickness direction of the housing 100 is arranged inside the housing 100.

[0518] The mounting member 900 can not only be used to mount the display panel 800, but also can decorate the front panel 150 to prevent the front panel 150 from reducing its aesthetic appearance due to the setting of the light-transmitting portion 152.

[0519] In some embodiments, a resisting portion 970 is provided on one side of the mounting member 900 located inside the housing 100. The resisting portion 970 is located at the edge of the third mounting portion 960, and the resisting portion 970 contacts the display panel 800 to prevent the display panel 800 from detaching from the third mounting portion 960 in the direction towards the front side of the housing 100.

[0520] It should be noted that by providing the resisting portion 970, the inner diameter dimension of the third mounting portion 960 is reduced, so that the display panel 800 can be prevented from detaching from the third mounting portion 960 in the direction from the rear side to the front side of the housing 100.

[0521] To prevent the display board 800 from moving randomly in the third installation part 960, a second protrusion part 810 is provided on the outer periphery of the display board 800, and the mounting part 900 is provided with an adaptation part 950. The adaptation part 950 is arranged on the outer edge of the third installation part 960, and the second protrusion part 810 is arranged inside the adaptation part 950 to fix the display board 800 and prevent the display board 800 from moving randomly in the third installation part 960. Fixing the display board 800 by means of the cooperation between the second protrusion part 810 and the adaptation part 950 can not only make the display board 800 and the mounting part 900 detachably connected, but also facilitate the installation and disassembly of the display board 800.

[0522] In some embodiments, the adaptation part 950 is in a structure such as a groove or a through groove. The second protrusion part 810 extends into the adaptation part 950. The adaptation part 950 fixes the display board 800 by applying constraints to the corresponding second protrusion part 810, so that the display board 800 is connected to the mounting part 900.

[0523] In some embodiments, multiple second protrusion parts 810 are provided, and multiple adaptation parts 950 are also provided. The multiple adaptation parts 950 and the multiple second protrusion parts 810 are arranged in one-to-one correspondence to increase the connection firmness between the display board 800 and the mounting part 900.

[0524] The multiple second protrusion parts 810 are unevenly distributed along the outer edge of the display board 800 to locate the installation position of the display board 800 in the third installation part 960 and prevent the display board 800 from being installed in the wrong position.

[0525] In some embodiments, the sizes of adjacent second protrusion parts 810 are different. Correspondingly, the sizes of adjacent adaptation parts 950 are also different, so that the second protrusion part 810 is matched with the corresponding adaptation part 950 to further locate the installation position of the display board 800 in the third installation part 960.

[0526] The second protrusion part 810 protrudes from the outer edge of the display board 800, and the second protrusion part 810 extends into the adaptation part 950. The farthest distance from the center of the second protrusion part 810 to the center of the display board 800 is greater than the farthest distance from the center of the adaptation part 950 to the center of the third installation part 960. The second protrusion part 810 will interfere with the inner edge of the third installation part 960, resulting in no deformation of the display board 800 or the mounting part 900, and the display board 800 cannot be installed in the third installation part 960. If the second protrusion part 810 or the adaptation part 950 is acted on by an external force to make the second protrusion part 810 arranged inside the adaptation part 950, it is easy to cause damage to the display board 800.

[0527] Such as Fig.48As shown in the figure, in order to reduce the damage to the display panel 800 when the second protrusion 810 is provided on the fitting portion 950, in this embodiment, a reserved area 801 is provided on the outer periphery of the display panel 800, and the second protrusion 810 is not provided in the reserved area 801. The second protrusion 810 is provided in the non-reserved area 801 of the display panel 800 to prevent the reserved area 801 from interfering with the inner edge of the third mounting portion 960, thereby reducing the damage to the display panel 800 during installation.

[0528] Specifically, when installing the display panel 800, the display panel 800 is tilted so that the second protrusions 810 provided in the non-reserved area 801 are arranged in one-to-one correspondence with the fitting portions 950. At this time, the distance between the reserved area 801 of the display panel 800 and the mounting member 900 in the thickness direction of the casing 100 is greater than the distance between the non-reserved area 801 of the display panel 800 and the mounting member 900 in the thickness direction of the casing 100. After the second protrusions 810 are arranged in one-to-one correspondence with the fitting portions 950, the reserved area 801 is moved in the thickness direction of the casing 100 toward the direction close to the third mounting portion 960 so that the reserved area 801 contacts the corresponding resisting portion 970. Since the second protrusions 810 are not provided in the reserved area 801, when the reserved area 801 of the display panel 800 moves in the thickness direction of the casing 100 toward the direction close to the third mounting portion 960, the reserved area 801 will not interfere with the third mounting portion 960, thereby reducing the damage to the display panel 800 during the installation process.

[0529] It should be noted that the outer diameter of the portion of the display panel 800 where the second protrusions 810 are not provided is usually smaller than the inner diameter of the third mounting portion 960, so as to have a fitting gap between the display panel 800 and the third mounting portion 960, thereby ensuring that the display panel 800 can be installed in the third mounting portion 960 and reducing the damage to the display panel 800 during the installation process.

[0530] Although not providing the second protrusions 810 in the reserved area 801 of the display panel 800 can facilitate the installation of the display panel 800 in the third mounting portion 960 and can reduce the loss to the display panel 800 during the installation process, however, since there is a lack of constraint between the reserved area 801 of the display panel 800 and the third mounting portion 960, it is easy to cause the display panel 800 to be installed insecurely. Therefore, in some embodiments, the second protrusions 810 are also provided in the reserved area 801 of the display panel 800, and the first elastic portion 910 is provided on the mounting member 900, and the first elastic portion 910 is used in cooperation with the second protrusions 810 provided in the reserved area 801 to constrain the reserved area 801 of the display panel 800.

[0531] Specifically, as Fig.47As shown, the first elastic part 910 is located at the outer edge of the third mounting part 960, and the first elastic part 910 and the adaptation part 950 are distributed along the circumferential direction of the outer edge of the third mounting part 960.

[0532] The distance between the first elastic part 910 and the center of the third mounting part 960 is greater than the distance between the adaptation part 950 and the center of the third mounting part 960.

[0533] The first elastic part 910 cooperates with the second protrusion part 810 arranged in the reserved area 801, so that the first elastic part 910 restricts the second protrusion part 810.

[0534] The first elastic part 910 can move in the direction towards or away from the center of the third mounting part 960.

[0535] When installing the display board 800, move the first elastic part 910 in the direction away from the center of the third mounting part 960 to prevent the first elastic part 910 from interfering with the second protrusion part 810 arranged in the reserved area 801 and affecting the installation of the display board 800.

[0536] After the display board 800 is installed in the third mounting part 960, move the first elastic part 910 in the direction towards the center of the third mounting part 960, so that the first elastic part 910 cooperates with the second protrusion part 810, thereby fixing the display board 800.

[0537] The outer periphery of the mounting part 900 is provided with a sixth connection part 930 and a seventh connection part 940. The sixth connection part 930 and the seventh connection part 940 are arranged correspondingly. The sixth connection part 930 contacts the side of the front panel 150 facing the front side of the cabinet 100, and the seventh connection part 940 contacts the side of the front panel 150 facing the inside of the cabinet 100, so that the mounting part 900 is connected to the front panel 150.

[0538] It should be noted that the sixth connection part 930 and the seventh connection part 940 are respectively arranged at the outer edge of the third mounting part 960.

[0539] There is a distance between the sixth connection part 930 and the seventh connection part 940 along the direction from the front side of the cabinet 100 to the rear side of the cabinet 100, so that the sixth connection part 930 and the seventh connection part 940 jointly define and form a locking part.

[0540] The front panel 150 is provided with an extension part 153. The extension part 153 is located at the inner edge of the light-transmitting part 152; the extension part 153 is arranged in the locking part, so that the mounting part 900 is connected to the front panel 150.

[0541] In some embodiments, the locking part is a limiting channel, and the inner edge of the light-transmitting part 152 is arranged in the limiting channel, so that the mounting part 900 is connected to the front panel 150.

[0542] The extension parts 153 are provided in multiple numbers, and the multiple extension parts 153 are distributed along the inner edge of the light-transmitting part 152. There is a passing part between two adjacent extension parts 153, and the seventh connecting part 940 is correspondingly arranged with the passing part, so that the seventh connecting part 940 passes through the front panel 150 through the passing part and is arranged.

[0543] The seventh connecting parts 940 are provided in multiple numbers, and the multiple second connecting parts 125 are distributed along the edge of the third installation part 960. There is a second passing part 124 between two adjacent seventh connecting parts 940, and the extension part 153 is correspondingly arranged with the second passing part 124. The extension part 153 is arranged in the locking part or leaves the locking part through the second passing part 124.

[0544] When the installation part 900 is connected to the front panel 150, the seventh connecting part 940 passes through the front panel 150 through the passing part and is arranged on the side of the front panel 150 facing the rear side of the casing 100, and then the installation part 900 is rotated to make the extension part 153 arranged in the locking part, so that the installation part 900 is connected to the front panel 150. It should be noted that when the extension part 153 is arranged in the locking part.

[0545] In some embodiments, the extension part 153 is provided with a guiding part, and the guiding part is arranged along the rotation direction of the installation part 900 to guide the movement of the locking part, so as to arrange the extension part 153 in the locking part.

[0546] It should be noted that as Fig.43 shown, the guiding part is an inclined surface arranged along the rotation direction of the installation part 900, so that the thickness of the extension part 153 increases along the rotation direction of the third installation part 960.

[0547] The front panel 150 is provided with a first limiting part 154, and the first limiting part 154 is located inside the casing 100 and at the edge of the light-transmitting part 152. The installation part 900 is provided with a second limiting part 920, and the second limiting part 920 is located on the outer periphery of the installation part 900. The second limiting part 920 is correspondingly arranged with the first limiting part 154 to position the connection position between the installation part 900 and the casing 100.

[0548] In some embodiments, the installation part 900 is provided with a protruding part, and the protruding part is located on the outer edge of the third installation part 960. The second limiting part 920 and the first elastic part 910 are respectively arranged on the protruding part.

[0549] In some embodiments, the second protruding part 810 includes a first convex block 811, and the first convex block 811 is arranged in the reserved area 801 of the display board 800.

[0550] In some embodiments, the second protruding part 810 includes a second convex block 812, and the second convex block 812 is arranged on the outer periphery of the display board 800.

[0551] In some embodiments, the second protrusion 810 includes a third bump 813, and the third bump 813 is disposed on the outer periphery of the display panel 800.

[0552] In some embodiments, the second protrusion 810 includes a fourth bump 814, and the fourth bump 814 is disposed on the outer periphery of the display panel 800.

[0553] In some embodiments, the second protrusion 810 includes a fifth bump 815, and the fifth bump 815 is disposed on the outer periphery of the display panel 800.

[0554] It should be noted that the first bump 811, the second bump 812, the third bump 813, the fourth bump 814, and the fifth bump 815 are non-uniformly distributed along the circumferential direction of the display panel 800.

[0555] Taking the second protrusion 810 including the first bump 811, the second bump 812, the third bump 813, the fourth bump 814, and the fifth bump 815 as an example, the assembly process of the display panel 800 and the mounting member 900 will be introduced in detail. Among them, the first bump 811, the second bump 812, the third bump 813, the fourth bump 814, and the fifth bump 815 are non-uniformly distributed along the circumferential direction of the display panel 800, and the first bump 811 is disposed in the reserved area 801 of the display panel 800.

[0556] The installation steps of the display panel 800 are as follows: Move the first elastic portion 910 in the thickness direction of the housing 100 away from the center of the third mounting portion 960 to prevent the first elastic portion 910 from interfering with the first bump 811. Dispose the second bump 812, the third bump 813, the fourth bump 814, and the fifth bump 815 in the corresponding fitting portions 950. Then, bring the reserved area 801 of the display panel 800 into contact with the resisting portion 970. Finally, move the first elastic portion 910 in the thickness direction of the housing 100 toward the center of the third mounting portion 960 so that the first elastic portion 910 cooperates with the first bump 811, and the first elastic portion 910 exerts a constraint on the first bump 811 to fix the display panel 800, thereby disposing the display panel 800 in the third mounting portion 960.

[0557] The installation steps of the mounting member 900 are as follows: Pass the mounting member 900 through the through portion and dispose it on the side of the front panel 150 facing the rear side of the housing 100. At this time, the extension portion 153 and the second through portion 124 are staggeredly distributed. Rotate the mounting member 900 so that the extension portion 153 is disposed in the locking portion to connect the mounting member 900 with the front panel 150.

[0558] The above-mentioned wall-mounted air conditioner indoor unit installs the display panel 800 by setting the mounting member 900, and utilizes the detachable connection between the mounting member 900 and the front panel 150 to realize the installation of the display panel 800.

[0559] In some embodiments, by providing a light-transmitting portion 152 on the front panel 150 and a third mounting portion 960 on the mounting member 900, the display panel 800 is disposed within the third mounting portion 960, and the light-transmitting portion 152 is provided corresponding to the third mounting portion 960, so that the display content of the display panel 800 can pass through the light-transmitting portion 152 and be transmitted.

[0560] In some embodiments, by providing a second protrusion 810 on the outer periphery of the display panel 800 and a fitting portion 950 on the outer edge of the third mounting portion 960, the second protrusion 810 and the fitting portion 950 are provided corresponding to each other to fix the display panel 800, so that the display panel 800 is disposed at the third mounting portion 960.

[0561] In some embodiments, by unevenly distributing the second protrusions 810 along the outer periphery of the display panel 800, the display panel 800 is positioned to prevent the display panel 800 from being installed in the reverse direction.

[0562] In some embodiments, by providing a first elastic portion 910 on the outer edge of the third mounting portion 960, the first elastic portion 910 and the second protrusion 810 are provided corresponding to each other to prevent the first elastic portion 910 from interfering with the second protrusion 810 and causing the display panel 800 to be unable to be installed in the third mounting portion 960. And when the display panel 800 is installed in the third mounting portion 960, the first elastic portion 910 restrains the second protrusion 810 to increase the firmness of the installation of the display panel 800.

[0563] In some embodiments, by providing a sixth connecting portion 930 and a seventh connecting portion 940 on the outer periphery of the mounting member 900, the sixth connecting portion 930 and the seventh connecting portion 940 jointly define a locking portion, and by providing an extension portion 153 on the edge of the light-transmitting portion 152, the extension portion 153 is matched with the locking portion to install the mounting member 900 on the front panel 150.

[0564] In the above-mentioned wall-mounted air conditioner indoor unit, the method of installing the display panel 800 by providing the mounting member 900 occupies a small space, can save the space inside the casing 100, and reduces the thickness dimension of the casing 100; or on the premise of the same thickness of the casing 100, a larger safety distance is provided for structures such as the display panel 800 and the heat exchanger 300 to avoid damage and failure of the internal structure during the process of falling and colliding. Not only is the installation method of the display panel 800 and the mounting member 900 simple and convenient, but also the display panel 800 is firmly installed and accurately positioned.

[0565] Such as Figure 4 And Figure 5As shown, the air conditioner indoor unit may include air guide vanes 500. The air guide vanes 500 are arranged at the first air inlet 101. The air guide vanes 500 are provided in multiple numbers, and the multiple air guide vanes 500 are distributed along the length direction of the casing 100 to guide the air conditioner air to be output from the first air outlet 102 to the indoor direction and increase the air outlet range of the air conditioner air.

[0566] As Fig.80 and Fig.104 shown, the air guide vanes 500 are connected with a third motor 510. The third motor 510 is installed on the base 140 and is used to drive the air guide vanes 500 to rotate, so that when the air conditioner air passes through the air guide vanes 500, the output direction to the indoor is changed by the air guide vanes 500, and the air outlet range when the air conditioner air is output to the indoor can also be increased.

[0567] In order to facilitate the third motor 510 to drive the multiple air guide vanes 500 to rotate, as Fig.81 and Fig.85 shown, the air guide vanes 500 are connected with a connecting rod 540. The connecting rod 540 extends along the length direction of the casing 100. The multiple air guide vanes 500 are connected to each other through the connecting rod 540. The third motor 510 is connected to one end of the connecting rod 540 along the length direction of the casing 100. The third motor 510 drives the connecting rod 540 to move, so that the connecting rod 540 drives the multiple air guide vanes 500 to rotate.

[0568] As Figure 80-Figure 84 shown, the air guide vanes 500 are also rotatably connected with a mounting plate 530. The mounting plate 530 extends along the length direction of the casing 100. The multiple air guide vanes 500 are respectively connected to the mounting plate 530.

[0569] The air guide vanes 500 are also provided with a first middle part 502. The first middle part 502 is arranged at a position of the air guide vanes 500 close to the connecting rod 540. One end of the first middle part 502 far from the air guide vanes 500 is rotatably connected with the connecting rod 540. The mounting plate 530, the first middle part 502 and the connecting rod 540 jointly define a four-bar linkage structure. When the third motor 510 drives the connecting rod 540 to move along the length direction of the casing 100, the air guide vanes 500 rotate under the action of the connecting rod 540.

[0570] When the connecting rod 540 moves along the length direction of the casing 100, since the air guide vanes 500 are rotatably connected with the mounting plate 530, the mounting plate 530 exerts a constraint on the air guide vanes 500, resulting in that the air guide vanes 500 cannot move along the length direction of the casing 100. However, the connecting rod 540 exerts a force on the air guide vanes 500 to move along the length direction of the casing 100. Therefore, the air guide vanes 500 will rotate so that one end of the first middle part 502 connected with the connecting rod 540 moves along the length direction of the casing 100 with the connecting rod 540.

[0571] It should be noted that the mounting plate 530 , the first middle portion 502 and the connecting rod 540 together define a four-bar connecting rod structure, which is common knowledge in the art and will not be described in detail herein.

[0572] In some embodiments, the wind guide blade 500 is provided with a first rotating portion 501 , which is rotatably connected to the mounting plate 530 , and the end of the first middle portion 502 away from the wind guide blade 500 is provided on the second rotating portion 503 , which is rotatably connected to the connecting rod 540 .

[0573] In some embodiments, the mounting plate 530 is provided with a first mounting opening 531 , which penetrates the mounting plate 530 in a direction perpendicular to the extension direction of the mounting plate 530 ; the first rotating portion 501 is provided in the first mounting opening 531 so that the air guide blade 500 is rotatably connected to the mounting plate 530 .

[0574] In order to ensure that the wind guide blade 500 can be reliably connected to the connecting rod 540 for rotation, Fig.87 As shown, the connecting rod 540 is provided with an inserting portion 543 , and the second rotating portion 503 is provided at the inserting portion 543 , so that the wind guide blade 500 is rotatably connected to the connecting rod 540 , and the connecting rod 540 drives the wind guide blade 500 to rotate.

[0575] like Fig.89 As shown, an anti-slip portion 504 is provided at one end of the second rotating portion 503 away from the first middle portion 502 , and the anti-slip portion 504 passes through the insertion portion 543 and is provided at a side of the connecting rod 540 away from the mounting plate 530 .

[0576] The size of the anti-slip portion 504 is matched with the size of the insertion portion 543 so that the anti-slip portion 504 cannot pass through the insertion portion 543 under the action of external force, thereby increasing the reliability of the connection between the first middle portion 502 and the connecting rod 540, and further increasing the reliability of the connecting rod 540 driving the multiple wind guide blades 500 to rotate.

[0577] It should be noted that the size of the second rotating portion 503 is matched with the size of the inserting portion 543 , so that the second rotating portion 503 can rotate freely in the inserting portion 543 .

[0578] like Fig.87 As shown, the connecting rod 540 is provided with a second elastic portion 541 , and the second elastic portion 541 extends along the length direction of the housing 100 .

[0579] The inserting portion 543 is disposed at a middle portion of the second elastic portion 541 along the length direction of the housing 100 .

[0580] Set the direction perpendicular to the extending direction of the connecting rod 540 in the plane where the side of the insertion part 543 of the connecting rod 540 is located as the first direction. The dimension of the second elastic part 541 along the first direction is smaller than the dimension of the insertion part 543 along the first direction. The second elastic part 541 makes the connecting rod 540 elastically deformed to increase the dimension of the insertion part 543, so that the anti - detachment part 504 can pass through the insertion part 543 from the side of the connecting rod 540 facing the mounting plate 530 and be arranged on the side of the connecting rod 540 away from the mounting plate 530.

[0581] In some embodiments, the second elastic part 541 is a long - slot hole, and the insertion part 543 is a through - hole. Second elastic parts 541 are respectively arranged at both ends of the insertion part 543 along the length direction of the machine shell 100. The dimension of the long - slot hole along the first direction is smaller than the dimension of the through - hole along the first direction. The dimension of the second rotating part 503 along the first direction is larger than the dimension of the through - hole along the first direction. By deforming the two side edges of the long - slot hole along the length direction of the machine shell 100, the dimension of the through - hole along the first direction is increased, so that the second rotating part 503 is arranged through the through - hole.

[0582] As Fig.85 shown, the third motor 510 is connected with a connecting piece 520. The connecting piece 520 is arranged at one end of the connecting rod 540 along the length direction of the machine shell 100. The third motor 510 drives the connecting rod 540 to rotate through the connecting piece 520.

[0583] As Fig.88 shown, the connecting piece 520 is provided with a fourth positioning part 522. The motor shaft 512 of the third motor 510 is arranged in the fourth positioning part 522 so that the third motor 510 is connected with the connecting piece 520.

[0584] The connecting piece 520 is further provided with a third rotating part 521. The third rotating part 521 is rotatably connected to the mounting plate 530.

[0585] At a position of the third rotating part 521 far from the connecting rod 540, a second intermediate part 524 is provided. One end of the second intermediate part 524 far from the third rotating part 521 is rotatably connected to the connecting rod 540. The second intermediate part 524, the connecting rod 540, the first intermediate part 502 and the mounting plate 530 jointly define a four - bar linkage structure.

[0586] The third motor 510 drives the connecting rod 540 to move through the connecting piece 520, so that the connecting rod 540 drives a plurality of air - guiding vanes 500 to rotate.

[0587] It should be noted that the connecting rod 540 converts the rotational motion of the connecting piece 520 into a linear motion of the connecting rod 540 along the length direction of the machine shell 100, and the air - guiding vanes 500 convert the linear motion of the connecting rod 540 along the length direction of the machine shell 100 into the rotational motion of the air - guiding vanes 500.

[0588] It should also be noted that the second middle portion 524 , the connecting rod 540 , the first middle portion 502 and the mounting plate 530 together define a four-bar connecting rod structure, which is common knowledge in the art and will not be described in detail here.

[0589] In some embodiments, the third rotating portion 521 is disposed in the first mounting opening 531 so that the connecting member 520 is rotatably connected to the mounting plate 530 .

[0590] In some embodiments, the connecting rod 540 is provided with a second installation opening 544 , and the second installation opening 544 is provided through the connecting rod 540 in a direction perpendicular to the extending direction of the connecting rod 540 .

[0591] The fourth rotating portion 523 is disposed in the second installation opening 544 so that the connecting member 520 and the connecting rod 540 are rotatably connected.

[0592] In the prior art, due to the influence of factors such as the second installation opening 544 being disposed at one end of the connecting rod 540 along the length direction of the housing 100 and the connecting rod 540 being driven by a third motor 510 , the connecting rod 540 is usually a non-mirror structure.

[0593] In order to improve the assembly efficiency of the connecting rod 540 and the wind guide blade 500, as shown in FIG. Fig.87 As shown, the connecting rod 540 is provided with an anti-mistake portion 542 , and the anti-mistake portion 542 is provided on a side of the connecting rod 540 away from the mounting plate 530 to locate the installation position of the connecting rod 540 .

[0594] In some embodiments, the fool-proofing portion 542 is disposed on a protruding surface of the connecting rod 540 , and the fool-proofing portion 542 is disposed on an outer edge of the inserting portion 543 .

[0595] When the third motor 510 drives the connecting rod 540 to move until the extension direction of the connecting rod 540 is in line with the rotation center of the air guide blade 500, the connecting rod 540 is likely to get stuck due to being in a dead point position, resulting in the third motor 510 being unable to drive the connecting rod 540 to move. At this time, the air guide blade 500 will be at a certain angle and unable to rotate. Since the air-conditioning wind will be affected by the air guide blade 500 when passing through the air guide blade 500, when the angle of the air guide blade 500 when the connecting rod 540 is stuck is not the angle required by the user, the air outlet direction and air outlet range of the air-conditioning wind may not be what the user needs, which can easily reduce the user experience. In addition, the jamming of the connecting rod 540 can easily cause damage to the third motor 510.

[0596] In this embodiment, a blocking portion 534 is provided on the movement trajectory of the connecting rod 540, and the blocking portion 534 is located before the dead point position of the connecting rod 540 along the movement trajectory of the connecting rod 540, so that the connecting rod 540 contacts the blocking portion 534 before moving to the dead point position, so that the blocking portion 534 prevents the connecting rod 540 from continuing to rotate, thereby preventing the connecting rod 540 from moving to the dead point position.

[0597] Specifically, the blocking part 534 is installed on the mounting plate 530. The blocking part 534 is located between two adjacent air guiding vanes 500, and the blocking part 534 and the two adjacent air guiding vanes 500 are distributed along the length direction of the casing 100.

[0598] When the third motor 510 drives the connecting rod 540 to move along the length direction of the casing 100 until it contacts the blocking part 534, the blocking part 534 prevents the connecting rod 540 from continuing to move.

[0599] In some embodiments, an extension line is defined along the extending direction of the connecting rod 540 at the rotation center of the air guiding vane 500. The dead center position is usually located on the extension line, and the blocking part 534 is located above the extension line, so that the blocking part 534 is arranged on the movement track of the connecting rod 540 before the dead center position of the connecting rod 540.

[0600] The blocking part 534 is located between the first rotating part 501 and the connecting rod 540 along the first direction, so that the blocking part 534 is arranged on the movement track of the connecting rod 540 before the dead center position of the connecting rod 540.

[0601] As Figure 80-Figure 84 shown, when the third motor 510 drives the connecting rod 540 to move along the length direction of the casing 100 towards both ends of the length direction of the casing 100 respectively, the connecting rod 540 will contact the blocking part 534. The blocking part 534 can not only prevent the connecting rod 540 from moving to the dead center position, but also limit the rotation angle of the air guiding vane 500, increasing the working reliability of the air guiding vane 500.

[0602] Since the connecting rod 540 and the mounting plate 530 are arranged at the first air outlet 102 and are likely to block the air-conditioning air from being output from the first air outlet 102 to the room, therefore, in this embodiment, an installation cavity 1412 is provided in the base 140. By arranging the connecting rod 540 and one end of the air guiding vane 500 connected to the connecting rod 540 in the installation cavity 1412, and using the mounting plate 530 to close the opening of the installation cavity, the influence of the connecting rod 540 on the air outlet effect of the air-conditioning air is prevented.

[0603] Specifically, as Fig.79 shown, the installation cavity 1412 is arranged at the first air outlet 102 and extends along the length direction of the casing 100.

[0604] The installation cavity 1412 is provided with an installation cavity opening corresponding to the first air outlet 102. The installation cavity opening extends along the length direction of the casing 100. The mounting plate 530 is installed on the base 140 and is arranged at the installation cavity opening.

[0605] The mounting plate 530 extends along the length direction of the casing 100; one end of the air guiding vane 500 connected to the connecting rod 540 is arranged in the installation cavity 1412, and the end of the air guiding vane 500 away from the connecting rod 540 is arranged at the first air outlet 102.

[0606] As Fig.75 and Fig.76 shown, the third motor 510 is located on the side of the base 140 facing away from the heat exchange channel. An opening is provided on the cavity wall of the installation cavity 1412 on the side opposite to the opening of the installation cavity. The motor shaft 512 of the third motor 510 passes through the opening and is connected to the connecting rod 540.

[0607] In some embodiments, as Figure 7 shown, the base 140 is provided with a clamping interface 145. The clamping interface 145 is provided on the cavity wall of the installation cavity 1412. The mounting plate 530 is provided with a hook portion 533. The hook portion 533 is correspondingly arranged with the clamping interface 145. The hook portion 533 is arranged in the clamping interface 145 so that the mounting plate 530 is arranged at the opening of the installation cavity.

[0608] In some other embodiments, the clamping interface 145 is an opening formed on the cavity wall of the installation cavity 1412.

[0609] In some embodiments, the base 140 is provided with a positioning port. The positioning port is correspondingly arranged with the installation cavity 1412.

[0610] The mounting plate 530 is provided with a second positioning block 532. The second positioning block 532 is correspondingly arranged with the positioning port. The second positioning block 532 is arranged in the positioning port to position the installation position of the mounting plate 530.

[0611] It should be noted that when installing the mounting plate 530, first place the second positioning block 532 in the positioning port, and then place the hook portion 533 in the clamping portion.

[0612] The working principle of the above air conditioner indoor unit is as follows: The third motor 510 drives the connecting rod 540 to move along the length direction of the casing 100 through the connecting member 520. The connecting rod 540 drives a plurality of air guiding vanes 500 to rotate to adjust the angles of the air guiding vanes 500, so that the air guiding vanes 500 guide the air conditioner air to be output from the first air outlet 102 to the room. When the connecting rod 540 moves to contact the blocking portion 534, the blocking portion 534 prevents the connecting rod 540 from continuing to move to prevent the connecting rod 540 from moving to the dead center position.

[0613] By providing the installation cavity 1412 at the first air outlet 102 of the above air conditioner indoor unit, and arranging one end of the connecting rod 540 and the air guiding vanes 500 connected to the connecting rod 540 in the installation cavity 1412, and closing the opening of the installation cavity with the mounting plate 530, not only can one end of the connecting rod 540 and the air guiding vanes 500 connected to the connecting rod 540 be hidden to maintain the aesthetics of the air conditioner indoor unit, but also the blocking effect of the connecting rod 540 on the air conditioner air can be reduced.

[0614] In some embodiments, a blocking portion 534 is provided on the mounting plate 530 so that the connecting rod 540 contacts the blocking portion 534 before moving to the dead point position, thereby preventing the connecting rod 540 from moving to the dead point position and increasing the reliability of the movement of the connecting rod 540.

[0615] In some embodiments, an anti-fouling portion 542 is provided on the connecting rod 540 to locate the installation position of the connecting rod 540 , thereby increasing the assembly efficiency of the connecting rod 540 and the wind guide blade 500 .

[0616] In some embodiments, the anti-detachment portion 504 is provided to increase the reliability of the air guide blade 500 and the connecting rod 540 by utilizing the anti-detachment portion 504 to prevent the air guide blade 500 from detaching from the connecting rod 540 during the movement of the connecting rod 540 .

[0617] The connecting rod 540 and the air guide blade 500 of the air conditioner indoor unit have high working reliability and good air guide effect.

[0618] The third motor 510 is located at a side of the base 140 away from the heat exchange channel. The third motor 510 includes a motor body 511 , and the motor body 511 is installed on the housing 100 .

[0619] The third motor 510 may include a motor shaft 512, which is rotatably connected to the motor body 511, and one end of the motor shaft 512 away from the motor body 511 is interconnected with the connecting rod 540; the motor shaft 512 is connected to the connecting rod 540, and the motor body 511 drives the motor shaft 512 to rotate, so that the motor shaft 512 drives the connection to move.

[0620] An ear portion 513 is disposed on the outer periphery of the motor body 511 , and a tenth connecting portion 1429 is disposed on the base 140 . The tenth connecting portion 1429 and the ear portion 513 are connected to each other via a fastener, so that the motor body 511 is installed on the housing 100 .

[0621] It should be noted that the fasteners are components such as bolts or screws.

[0622] like Fig.105 As shown, the base 140 is provided with a fourth mounting portion 142 , and the third motor 510 is placed on the fourth mounting portion 142 , so that the fourth mounting portion 142 supports the third motor 510 , thereby increasing the firmness of the installation of the third motor 510 .

[0623] In some embodiments, the fourth mounting portion 142 is disposed on the front side of the base 140 , and the fourth mounting portion 142 is located outside the heat exchange channel.

[0624] The fourth mounting portion 142 is provided with a buffer portion 143 . The buffer portion 143 is used to increase the elasticity of the fourth mounting portion 142 . The buffer portion 143 is provided on a wall surface where the fourth mounting portion 142 contacts the third motor 510 .

[0625] In some embodiments, the buffer portion 143 is an opening formed in the fourth mounting portion 142. The opening direction of the opening of the fourth mounting portion 142 intersects with the axis of the motor shaft 512 of the third motor 510, so as to prevent other objects from contacting the motor shaft 512 of the third motor 510 through the buffer portion 143.

[0626] When the air conditioner indoor unit undergoes a drop test or transportation, the outer cover 110 is subjected to an impact force, and the impact force is transmitted to the fourth mounting portion 142. The fourth mounting portion 142 will undergo elastic deformation under the action of the buffer portion 143, thereby preventing the base 140 from cracking or being damaged. When the base 140 undergoes elastic deformation, the supporting effect of the base 140 on the outer cover 110 is weakened, so that the outer cover 110 can undergo adaptable elastic deformation, thereby preventing the outer cover 110 from cracking or having white marks.

[0627] A through portion 124 is provided on the cavity wall on the side of the installation cavity 1412 opposite to the opening of the installation cavity. The motor shaft 512 of the third motor 510 passes through the through portion 124 and is connected to the connecting rod 540.

[0628] A fifth positioning portion 514 is provided at one end of the motor shaft 512 connected to the connecting rod 540. The fifth positioning portion 514 is correspondingly arranged with the fourth positioning portion 522, and the fifth positioning portion 514 is arranged inside the fourth positioning portion 522 to connect the motor shaft 512 and the connecting rod 540 to each other.

[0629] In some embodiments, the fifth positioning portion 514 is provided with a fifth mating surface, and the fifth mating surface is arranged on the outer peripheral wall of the motor shaft 512; the fourth positioning portion 522 is provided with a sixth mating surface, and the sixth mating surface is correspondingly arranged and cooperates with the fifth mating surface to connect the motor shaft 512 and the connecting rod 540 to each other.

[0630] In some other embodiments, the fifth mating surface is provided in two, and the two fifth mating surfaces are correspondingly arranged; the sixth mating surface is also provided in two, and the two sixth mating surfaces are arranged in one-to-one correspondence with the two fifth mating surfaces.

[0631] When the third motor 510 is mounted on the base 140 and the motor shaft 512 drives the connecting rod 540 to move through the connecting member 520, the ear portion 513 is correspondingly arranged with the tenth connecting portion 1429, and the fifth positioning portion 514 is correspondingly arranged with the fourth positioning portion 522. Conversely, when the ear portion 513 is correspondingly arranged with the tenth connecting portion 1429 and the fifth positioning portion 514 is correspondingly arranged with the fourth positioning portion 522, the third motor 510 can be mounted on the base 140 and the motor shaft 512 can drive the connecting rod 540 to move through the connecting member 520.

[0632] Since the position of the fourth positioning portion 522 changes with the movement of the connecting rod 540, it can be seen that the setting position of the sixth mating surface in the fourth positioning portion 522 also changes with the movement of the connecting rod 540. Therefore, in order to facilitate the installation of the third motor 510, usually when the connecting rod 540 moves to the first position, the ear portion 513 is correspondingly arranged with the tenth connecting portion 1429, and when the fifth positioning portion 514 is correspondingly arranged with the fourth positioning portion 522, the third motor 510 is installed.

[0633] It should be noted that in practical applications, in order to conveniently determine that the connecting rod 540 moves to the first position, usually the limit position of the connecting rod 540 is selected as the first position, and the limit position of the connecting rod 540 is the position where the connecting rod 540 cannot move further.

[0634] The connecting rod 540 can drive the air guiding vane 500 to rotate. Conversely, by driving the air guiding vane 500 to rotate, the connecting rod 540 can also be driven to move. When installing the third motor 510, by driving the air guiding vane 500 to rotate to the position where it cannot rotate further, at this time, the connecting rod 540 also moves to the position where it cannot move further, that is, the connecting rod 540 moves to the first position. This belongs to the well-known common sense technology in the field and will not be elaborated here.

[0635] Since the motor body 511 is rotationally connected to the motor shaft 512, the motor body 511 and the motor shaft 512 can usually be relatively rotated by applying an external force to the motor body 511 or the motor shaft 512.

[0636] In practical applications, due to reasons such as transportation or manufacturing, the positional relationship between the fifth positioning portion 514 and the ear portion 513 is not completely consistent, resulting in that when the connecting rod 540 moves to the first position, the ear portion 513 and the tenth connecting portion 1429, and the fifth positioning portion 514 and the fourth positioning portion 522 cannot be correspondingly arranged simultaneously, so that the third motor 510 cannot be installed on the base 140.

[0637] In the prior art, a calibration tooling is usually set to correct the positional relationship between the fifth positioning portion 514 and the ear portion 513, so that when the connecting rod 540 moves to the first position, the ear portion 513 and the tenth connecting portion 1429, and the fifth positioning portion 514 and the fourth positioning portion 522 are correspondingly arranged simultaneously.

[0638] Since there are various specifications of the third motor 510, the calibration tooling is also designed in various specifications. In actual production, it is necessary to select the corresponding calibration tooling according to the specification of the third motor 510, which will increase the installation time of the third motor 510 and reduce the installation efficiency of the third motor 510.

[0639] In this embodiment, a calibration part is provided on the base 140. By correspondingly setting the specifications of the calibration part and the third motor 510 installed on the base 140, the time for selecting a calibration tooling is saved, the installation time of the third motor 510 is reduced, and the installation efficiency of the third motor 510 is improved.

[0640] Specifically, as Fig.108 shown, the calibration part includes a second restraint part 1426, and the second restraint part 1426 is used to restrain the motor shaft 512.

[0641] The calibration part includes a second abutting part 1427, and the second abutting part 1427 is used to limit the rotation of the motor body 511.

[0642] When the motor shaft 512 interacts with the second restraint part 1426 and the motor body 511 contacts the second abutting part 1427, the ear part 513 is correspondingly set with the tenth connecting part 1429, and the fifth positioning part 514 is also correspondingly set with the fourth positioning part 522 of the connecting rod 540 at the first position.

[0643] When calibrating the third motor 510, first make the motor shaft 512 interact with the second restraint part 1426, and by rotating the motor body 511, make the motor body 511 contact the second abutting part 1427, so as to realize the calibration of the positional relationship between the fifth positioning part 514 and the ear part 513.

[0644] In some embodiments, as Fig.108 shown, an arc part 1428 is provided beside the second abutting part 1427. When the motor body 511 rotates, it rotates along the edge of the arc part 1428. When the relative positional relationship between the ear part 513 and the fifth positioning part 514 matches the relative positional relationship between the tenth connecting part 1429 and the fourth positioning part 522, the outer periphery of the motor body 511 abuts against the arc part 1428.

[0645] In some embodiments, the second restraint part 1426 is defined with a concave part. The motor shaft 512 is arranged in the concave part, the motor body 511 is arranged outside the concave part, and the side of the motor body 511 connecting the motor shaft 512 contacts the outer edge of the opening of the concave part.

[0646] In some embodiments, when the motor shaft 512 is arranged in the concave part, two fifth mating surfaces are correspondingly arranged along the length direction of the machine shell 100, and the two fifth mating surfaces correspond to the two side walls of the concave part along the length direction of the machine shell 100 one by one. The side walls of the concave part interact with the fifth mating surfaces to prevent the motor shaft 512 and the motor body 511 from rotating synchronously.

[0647] The minimum distance between the two side walls of the concave portion is less than the diameter of the motor shaft 512. When the fifth positioning portion 514 is provided in the concave portion, the side wall of the concave portion interacts with the fifth mating surface to prevent the motor shaft 512 from rotating synchronously with the motor body 511.

[0648] It should be noted that the depth of the concave portion is greater than the length of the motor shaft 512, and the dimension of the end of the motor body 511 facing the concave portion is greater than the dimension of the outer edge of the concave portion, so that when the motor shaft 512 is provided in the concave portion, the end of the motor body 511 connecting the motor shaft 512 can abut against the outer edge of the concave portion.

[0649] It should also be noted that in some embodiments, the fifth mating surface does not extend axially along the motor shaft 512 to the end where the motor shaft 512 is connected to the motor body 511.

[0650] The concave portion includes a first concave portion, and the two fifth mating surfaces are provided in one-to-one correspondence with the two side walls of the first concave portion along the length direction of the housing 100.

[0651] The concave portion may include a second concave portion. The second concave portion is located above the first concave portion. The opening dimension of the second concave portion is greater than the circumferential dimension of the motor shaft 512 and less than the circumferential dimension of the end of the motor body 511 connected to the motor shaft 512, so that the end of the motor shaft 512 close to the motor body 511 is provided in the second concave portion.

[0652] In addition, it should be noted that the axis of the motor shaft 512 and the axis of the motor body 511 are not collinear, and the axis of the motor shaft 512 is offset from the axis of the motor body 511.

[0653] In the above air conditioner indoor unit, as Figure 108-Figure 111 shown, the installation steps of the third motor 510 are as follows: First, insert the motor shaft 512 into the concave portion, so that the fifth mating surface is provided in correspondence with the two side walls of the concave portion along the length direction of the housing 100, and make the end of the motor body 511 connected to the motor shaft 512 contact the outer edge of the concave portion. Rotate the motor body 511 until the motor body 511 contacts the second abutting portion 1427, and the second abutting portion 1427 prevents the motor body 511 from continuing to rotate. At this time, the positional relationship between the fifth positioning portion 514 and the ear portion 513 is calibrated; Move the connecting rod 540 to the first position through the air deflector 500. At this time, the positional relationship between the fourth positioning portion 522 and the tenth connecting portion 1429 is provided in correspondence with the positional relationship between the fifth positioning portion 514 and the ear portion 513. Install the motor body 511 on the base 140, and the motor shaft 512 is provided in the fourth positioning portion 522, and the fifth mating surface is provided in correspondence with the sixth mating surface to complete the installation of the third motor 510.

[0654] The above air conditioner indoor unit sets a calibration part on the base 140, and uses the calibration part to calibrate the positional relationship between the motor shaft 512 and the ear part 513 of the third motor 510, so as to improve the installation efficiency of the third motor 510.

[0655] To facilitate the routing of the first wire, as Fig.77 shown, the base 140 is provided with a wire routing part 1410, and the wire routing part 1410 is arranged on the front side of the base 140 and above the second opening 149.

[0656] The wire routing part 1410 extends along the length direction of the housing 100; one end of the wire routing part 1410 along the length direction of the housing 100 is communicated with the accommodating cavity 104, and the other end of the wire routing part 1410 is arranged close to the installation part of the housing 100.

[0657] The third motor 510 is arranged outside the accommodating cavity 104. In order to enable the first wire to pass through the accommodating cavity 104 and be arranged in the wire routing part 1410, a path part 147 is provided on the cavity wall of the accommodating cavity 104 close to the third motor 510, and the first wire enters the accommodating cavity 104 through the path part 147.

[0658] It should be noted that the path part 147 is arranged on the lower side of the wire routing part 1410. After the first wire enters the accommodating cavity 104 through the path part 147, it walks upward close to the wire routing part 1410, and the first wire is connected to the electronic control board along the wire routing part 1410. The accommodating cavity 104 is the wire routing channel for the first wire.

[0659] It should also be noted that the path part 147 is arranged at the connection part of the protection plate 146 and the second installation part 148, and the first wire enters the accommodating cavity 104 through the path part 147.

[0660] The base 140 is provided with a constraint part 1411, and the constraint part 1411 is arranged on the wire routing part 1410. The constraint part 1411 is used to constrain the first wire so that the first wire walks along the wire routing part 1410.

[0661] In some embodiments, the wire routing part 1410 is arranged on the front side of the base 140, and the constraint part 1411 is used to hang the first wire.

[0662] In some embodiments, the second wire also passes through the wire routing part 1410 and is connected to the electronic control board.

[0663] In the above air conditioner indoor unit, the third motor 510 is installed on the fourth installation part 142, and the first wire connecting the third motor 510 and the electronic control board enters the accommodating cavity 104 through the path part 147 and is connected to the electronic control board through the accommodating cavity 104 and the wire routing part 1410.

[0664] The above-mentioned air conditioner indoor unit protects and hides the first electric wire by using the outer cover 110 with the wire routing part 1410 arranged on the front side of the base 140, so as to prevent the first electric wire from being damaged due to external force acting on it; the first electric wire enters the accommodation cavity 104 through the path part 147, then is connected to the electronic control board after passing through the wire routing part 1410, and a restraint member 1411 is arranged on the wire routing part 1410 to restrain the first electric wire, so as to prevent the first electric wire from being disordered during wire routing.
