[0088] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0089] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0090] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0091] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0092] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0093] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0094] like Figure 1-Figure 16 As shown, an air-conditioning indoor unit is provided in one embodiment of the present application, including a housing, a fan 200, and a heat exchanger.

[0095] Specifically, a heat exchanger and a fan 200 are installed inside the shell. During use, the fan 200 will drive the airflow to flow inside the shell, thereby allowing the outside air to enter the shell and be driven by the fan 200 to enter the shell to exchange heat with the heat exchanger 2. Finally, the gas after heat exchange is output to the outside of the shell.

[0096] like Fig.10 As shown in Figure 11, the fan 200 includes a motor 210 and a fan 220. The motor 210 needs to meet the requirements for installing the motor 210 and the fan 220.

[0097] like Figure 1 , Figure 3 , Figure 6 , Figure 8 , Fig.11 The housing includes a cover plate 110 , at least one enclosure plate, and at least one support plate 130 . The at least one enclosure plate is disposed along the circumference of the cover plate 110 .

[0098] The cover plate 110 and at least one enclosure plate are arranged to form a mounting cavity.

[0099] At least one supporting plate 130 is used to divide the mounting cavity into a plurality of sub-mounting cavities 141 .

[0100] like Fig.10 , Fig.12 As shown, the fan 200 and the heat exchanger are dispersedly arranged in a plurality of sub-mounting cavities 141 .

[0101] In some embodiments, Fig.10 As shown, there are two fans 220, and the two fans 220 are respectively connected to the two sides of the motor 210. Correspondingly, the support plate 130 needs to be configured to match the fans 220 and the motor 210.

[0102] In some other embodiments, Fig.12 As shown, there are three fans 220, and the three fans 220 are respectively connected to both sides of the motor 210. Correspondingly, the support plate 130 needs to be configured to match the fans 220 and the motor 210.

[0103] An air inlet side end 150 and an air outlet side end 160 are formed on the shell formed by the cover plate 110 and at least one enclosure plate.

[0104] The fan 200 is installed in the sub-installation cavity 141 communicating with the air inlet side end 150. The heat exchanger is installed in the sub-installation cavity 141 communicating with the air outlet side end 160.

[0105] The plurality of sub-mounting cavities 141 are connected, one end of the passage is connected to the air inlet side end 150 , and the other end of the passage is connected to the air outlet side end 160 .

[0106] In order to realize the automated assembly of the shell, the cover plate 110 is connected with at least one enclosure plate and at least one support plate 130 by using an automatic connection device.

[0107] In some embodiments of the present application, the automatic connection device includes an automatic riveting device.

[0108] That is, the cover plate 110 is connected to at least one enclosure plate and at least one support plate 130 by riveting. The riveting method can realize automatic assembly, instead of manual bolt connection, and improves the assembly efficiency of the shell.

[0109] In some other embodiments of the present application, the automatic connection device further comprises an automatic screw connection device, that is, the cover plate 110 is connected with at least one enclosure plate and at least one support plate 130 by automatic screw connection.

[0110] In some other embodiments of the present application, the automatic connection device further includes an automatic spot welding device, that is, the cover plate 110 is connected with at least one enclosure plate and at least one support plate 130 by automatic spot welding.

[0111] However, in order to further improve the assembly efficiency of the shell, the cover plate 110, the enclosure plate and the support plate 130 need to be pre-positioned before riveting to achieve rapid pre-positioning between the cover plate 110, the enclosure plate and the support plate 130, which can further improve the assembly efficiency of the shell.

[0112] In some embodiments of the present application, before the cover plate 110, the enclosure plate and the support plate 130 are riveted together, the shell is pre-positioned by snapping, and then the shell is assembled by riveting.

[0113] Specifically, the cover plate 110 and the enclosure are clamped together to pre-position the cover plate 110 and the enclosure, and then the cover plate 110 and the enclosure are riveted together.

[0114] Specifically, the cover plate 110 and the support plate 130 are snap-fitted to pre-position the cover plate 110 and the support plate 130 , and then the cover plate 110 and the support plate 130 are riveted.

[0115] In order to further improve the installation efficiency of the housing, the cover plate 110 may be in the form of a bent plate.

[0116] In some embodiments of the present application, the cover plate 110 can be bent to form an L-shape, and other surfaces of the shell are surrounded by enclosures.

[0117] In some other embodiments of the present application, the cover plate 110 can be bent to form a U-shaped bent plate, so that the two side walls of the housing and the upper cover located above are an integrated structure. The other side walls of the U-shaped bent plate that need to be closed are surrounded by a panel. This reduces the number of parts of the housing and further improves the assembly efficiency of the housing.

[0118] In the embodiment where the cover plate 110 is a U-shaped bent plate formed by bending, the U-shaped bent plate includes two oppositely disposed closed ends 111 and two oppositely disposed unclosed ends 112 .

[0119] The two oppositely disposed unclosed ends 112 of the U-shaped bending plate are respectively formed with an air inlet side end 150 and an air outlet side end 160 .

[0120] The air inlet side end 150 and the air outlet side end 160 are respectively formed at two opposite side ends of the housing.

[0121] The air inlet side end 150 is communicated with the air outlet side end 160 via a plurality of sub-mounting cavities 141 .

[0122] In some embodiments of the present application, there is one support plate 130 , which divides the installation cavity into an air inlet installation cavity 1411 and an air outlet installation cavity 1412 . The air inlet side end 150 is in communication with the air inlet installation cavity 1411 . The air outlet side end 160 is in communication with the air outlet installation cavity 1412 .

[0123] The heat exchanger is installed in the air outlet installation cavity 1412. The fan 200 is installed in the air inlet installation cavity 1411.

[0124] In order to achieve communication between the air inlet installation cavity 1411 and the air outlet installation cavity 1412 , a through hole 131 is opened on the support plate 130 , and the air inlet installation cavity 1411 and the air outlet installation cavity 1412 are communicated with each other through the through hole 131 .

[0125] In some embodiments, Fig.11 As shown, the number of the through holes 131 is three.

[0126] In other embodiments, Figure 3 As shown, the number of the through holes 131 is two.

[0127] The support plate 130 is used to support the installation cavity and separate the installation cavity at the same time.

[0128] In some embodiments of the present application, in order to achieve riveting between the cover plate 110 and the enclosure plate and support plate 130, a first flange structure 113 is formed by flanged edges of the cover plate 110, and the end of the enclosure plate abuts against the first flange structure 113 and is connected by riveting at the abutting point.

[0129] Specifically, the enclosure includes a flange plate 121, which is used for installing an air duct outside the factory.

[0130] The flange plate 121 is connected to the air outlet side end 160 of the U-shaped bending plate.

[0131] The flange plate 121 , the support plate 130 , and the cover plate 110 on one side of the support plate 130 surround and form an air outlet installation cavity 1412 .

[0132] An air outlet 1211 is provided on the flange plate 121 . The air outlet 1211 is communicated with the air outlet installation cavity 1412 .

[0133] In order to facilitate the riveting of the cover plate 110 and the flange plate 121, a second riveted portion 1212 is extended from one side end of the flange plate 121, and the position corresponding to the second riveted portion 1212 on the first flange structure 113 formed by bending at the closed end of the U-shaped bending plate is defined as a first riveted portion 1131, and riveting is performed at the place where the first riveted portion 1131 and the second riveted portion 1212 abut against each other.

[0134] Specifically, when the air conditioner indoor unit is in the installed state, the first riveted portion 1131 and the second riveted portion 1212 are extended in the vertical direction. The first riveted portion 1131 and the second riveted portion 1212 are riveted in a state of abutting against each other.

[0135] A fourth flange structure 1213 is extended and formed on the other side end of the flange plate 121 .

[0136] A third riveted portion 114 is formed at a position corresponding to the fourth flanging structure 1213 on the closed side end of the U-shaped bending plate, and the third riveted portion 114 and the fourth flanging structure 1213 are riveted together in a state of abutting against each other.

[0137] Specifically, when the air conditioner indoor unit is in the installed state, the fourth flange structure 1213 is extended in the vertical direction. The fourth flange structure 1213 extends on the other side end of the flange plate 121 in the vertical direction.

[0138] The third riveted portion 114 extends in the vertical direction and is formed on the closed side end of the U-shaped bent plate.

[0139] In order to achieve pre-positioning installation of the two side ends of the flange plate 121 in the vertical direction and the two closed side ends of the U-shaped bent plate cover plate 110, a first clamping portion 12131 is formed on the second riveted portion 1212, and a first clamping fitting portion 1132 is formed on the first riveted portion 1131 at a position corresponding to the position of the first clamping portion 12131.

[0140] The first clamping portion 12131 is clamped with the first clamping matching portion 1132 .

[0141] Specifically, the first clamping portion 12131 may be a first positioning buckle that is arranged upwardly and tilted. The first clamping matching portion 1132 may be a first positioning hole.

[0142] The first positioning card hole can be a long hole. After the first positioning card buckle is inserted into the first positioning card hole, the first positioning card buckle moves upward relative to the first positioning card hole, and the first positioning card buckle abuts against the upper wall of the first positioning card hole. The first positioning card buckle supports the first positioning card hole, so as to make the flange plate 121 hang relative to the cover plate 110. Thus, the flange plate 121 and the cover plate 110 are pre-positioned. Then, the first riveting part 1131 and the second riveting part 1212 are riveted.

[0143] Specifically, the specific number of the first positioning buckles is set according to the height of the side end of the flange plate 121 .

[0144] Specifically, two first positioning buckles may be used, and the two first positioning buckles are arranged at intervals in the vertical direction.

[0145] Specifically, in order to ensure the stable pre-positioning of the first positioning buckle and the first positioning hole, the first positioning buckle includes a first supporting portion 12132 and a first stop portion 12133. The first supporting portion 12132 can adopt a horizontally arranged supporting vertical plate, and the first supporting portion 12132 abuts against the first positioning hole to achieve support. The first stop portion 12133 is inclined upward relative to the first supporting portion 12132 to prevent the first positioning buckle from moving out of the first positioning hole, thereby ensuring the stable pre-positioning of the flange plate 121 and the cover plate 110.

[0146] In some embodiments of the present application, a fourth riveted portion 1214 is formed at the upper side end of the flange plate 121 adjacent to the first flange structure 113, and a fifth riveted portion 1133 is formed on the first flange structure 113 at a position corresponding to the fourth riveted portion 1214. The fourth riveted portion 1214 is riveted to the fifth riveted portion 1133.

[0147] Specifically, the fifth riveted portion 1133 may be a fifth riveted flange, and the fifth riveted flange is a part of the first flange structure.

[0148] The fifth riveted portion 1133 is a part of the first flange structure.

[0149] In order to achieve pre-positioning of the upper side end of the flange plate 121 and the cover plate 110 , a third clamping portion is extended along the upper side end of the flange plate 121 , and a third clamping fitting portion 11331 is formed on the fifth riveted portion 1133 , and the third clamping portion is clamped with the third clamping fitting portion 11331 .

[0150] Specifically, the third clamping portion is a clamping plate 122 extending along the upper side end of the flange plate 121 .

[0151] A plurality of first bending plates 1221 are formed on the clamping plate 122 .

[0152] The first bending plate 1221 is bent toward the first flange structure 113 .

[0153] The third snap-fitting portion 11331 is used to form a fifth riveted flange.

[0154] Specifically, the third snap-fitting portion 11331 is a through groove formed on the fifth riveted flange.

[0155] During the pre-positioning process, the side wall of the clamping plate 122 abuts against the fifth riveted flange, the first bent plate 1221 extends into the through slot, and the first bent plate 1221 abuts against the inner side wall of the fifth riveted flange at the connection with the through slot.

[0156] Since the flange plate 121 is relatively long in the horizontal direction, the flange plate 121 and the cover plate 110 may be pre-positioned before the flange plate 121 and the cover plate 110 are clamped together.

[0157] Therefore, a second positioning portion 12141 is formed on the fourth riveting portion 1214 , and a second positioning matching portion 11332 is formed on the third clamping portion, and the second positioning portion 12141 is positioned and matched with the second positioning matching portion 11332 .

[0158] Specifically, the second positioning and fitting portion 11332 is formed on the clamping plate 122 .

[0159] The second positioning portion 12141 is a positioning column formed on the upper side end of the flange plate 121 .

[0160] Specifically, the second positioning portion 12141 may be formed on the fourth riveting portion 1214 .

[0161] The second positioning and matching portion 11332 is a positioning and matching hole formed on the clamping plate 122 .

[0162] The positioning column is inserted into the positioning matching hole, thereby realizing the pre-positioning of the clamping plate 122 and the flange plate 121 .

[0163] When the positioning column is inserted into the positioning matching hole, the clamping plate 122 and the flange plate 121 are in a pre-positioning state, the first bending plate 1221 is inserted into the through groove, and the first bending plate 1221 abuts against the inner side wall of the fifth riveted flange at the connection between the through groove, thereby achieving further pre-positioning.

[0164] In this state, the fourth riveting portion 1214 is riveted to the fifth riveting portion 1133 , thereby achieving the installation of the flange plate 121 relative to the cover plate 110 .

[0165] Specifically, there are multiple first bending plates 1221 , and the multiple first bending plates 1221 are extended along the length direction of the clamping plate 122 and arranged at intervals.

[0166] The number of the through slots is equal to the number of the first bending plates 1221 .

[0167] In some embodiments of the present application, second flange structures 132 are formed on both side ends of the support plate 130 .

[0168] The two second flange structures 132 formed at both side ends of the support plate 130 are bent toward both sides of the support plate 130 , respectively. The second flange structures 132 bent toward both sides can enhance the structural strength of the support plate 130 .

[0170] A third flange structure 133 is formed at the upper side end of the support plate 130 adjacent to the cover plate 110 , and the third flange structure 133 is riveted to the cover plate 110 where they abut.

[0171] Since the third flange structure 133 is very long, in order to improve the structural strength of the third flange structure 133 , a plurality of evenly distributed reinforcing ribs may be formed on the third flange structure 133 .

[0172] A first positioning portion 1331 is formed on the third flange structure 133, and a first positioning matching portion 115 is formed on the cover plate 110 at a position corresponding to the first positioning portion 1331. The first positioning portion 1331 is inserted into the first positioning matching portion 115 to achieve pre-assembly positioning between the cover plate 110 and the support plate 130.

[0173] Specifically, the first positioning portion 1331 may be in the form of a positioning column. The first positioning matching portion 115 may be in the form of a positioning matching hole.

[0176] Specifically, the second clamping portion 116 can be in the form of a second bent plate. The second clamping fitting portion 1321 is a through slot provided on the second flange structure 132 .

[0177] In order to facilitate the installation of the support plate 130 in the U-shaped bending plate, the support plate 130 needs to be inserted from the lower end of the U-shaped bending plate into the two opposite closed ends 111 of the U-shaped bending plate, the second bending plate is bent toward the lower side, and the second bending plate bent toward the lower side is inserted into the through groove until the lower side wall of the through groove abuts against the bending part of the second bending plate.

[0178] The second bending plate is inserted into the through slot and moves along the through slot until the bending portion of the second bending plate abuts against the upper side wall of the through slot, thereby achieving the clamping connection between the support plate 130 and the cover plate 110 .

[0179] After the above-mentioned pre-positioning, the second flange structure 132 , the third flange structure 133 and the cover plate 110 are riveted.

[0184] Therefore, during the installation of the electrical box mounting plate 123 relative to the support plate 130, the electrical box mounting plate 123 moves upward from the open end of the U-shaped bending plate, so that the third bending plate is inserted into the through groove until the bending end of the third bending plate abuts against the lower side wall of the through groove.

[0185] Different numbers of fourth snap-fitting portions 12311 may be set according to the height of the fifth flange structure 1231 .

[0186] The number of the fourth locking portions 12311 is equal to the number of the fourth locking portions 134 .

The cover plate 110 where the sixth flange structure 1232 abuts against the cover plate 110 is defined as a fifth riveted portion, and the fifth riveted portion is riveted to the sixth flange structure 1232 .

[0189] A third positioning and fitting portion 12321 is formed on the sixth flange structure 1232 . Specifically, the third positioning and fitting portion 12321 may be in the form of a positioning hole.

[0190] A third positioning portion 117 is formed on the cover plate 110 . Specifically, the third positioning portion 117 may be in the form of a positioning column.

[0191] The third positioning portion 117 is positioned and matched with the third positioning matching portion 12321 .

[0192] During the assembly process of the air conditioner indoor unit, the formed cover plate 110 and the support plate 130 are positioned and matched with each other through the first positioning portion 1331 and the first positioning matching portion 115, the second clamping portion 116 is clamped with the second clamping matching portion 1321, and the fourth clamping portion 134 is clamped with the fourth clamping matching portion 12311, so as to realize the pre-positioning of the support plate 130 and the cover plate 110;

[0193] During the assembly process of the air conditioner indoor unit, the formed clamping plate 122 and the flange plate 121 are positioned and matched between the second positioning portion 12141 and the second positioning matching portion 11332, and the fifth riveted portion 1133 is clamped between the clamping plate 122 and the flange plate 121 through the plurality of bent plates 1221 formed on the clamping plate 122 and the through groove formed on the fifth riveted portion 1133, so as to achieve the pre-positioning between the flange plate 121 and the cover plate 110;

[0194] During the assembly process of the air conditioner indoor unit, after the pre-positioning between the cover plate 110 and the support plate 130 is completed, the pre-positioning between the electrical box mounting plate 123, the support plate 130 and the cover plate 110 is achieved by engaging the fourth clamping fitting portion 12311 of the electrical box mounting plate 123 with the fourth clamping fitting portion 134, and by positioning and matching the third positioning portion 117 with the third positioning fitting portion 12321;

[0195] During the assembly process of the air conditioner indoor unit, after the cover plate 110 and the support plate 130, the electrical box mounting plate 123 and the cover plate 110, the support plate 130, and the flange plate 121 and the cover plate 110 are pre-positioned, the second flange structure 132, the third flange structure 133 and the cover plate 110 are riveted by automated equipment to achieve the riveting of the support plate 130 and the cover plate 110;
