[0062] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0063] See also Figure 1 The embodiment of the present application provides an air conditioner 10. The air conditioner 10 provided by the embodiment of the present application can facilitate the installation of the air conditioner 10 and improve the production efficiency of the air conditioner 10.

[0064] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the air conditioner 10 includes: a shell 100, a water tray 210, an air duct assembly 510 and a fan assembly 520, the shell 100 has a accommodating chamber 112 and an air outlet 114 connected to the accommodating chamber 112, the water tray 210 is arranged in the accommodating chamber 112; the air duct assembly 510 is arranged in the accommodating chamber 112, and the air duct assembly 510 has an air outlet channel 512; the fan assembly 520 is arranged in the air outlet channel 512; wherein the air duct assembly 510 is detachably connected to the water tray 210.

[0065] The housing 100 is the main body of the entire air conditioner 10, and provides a mounting base for other components of the air conditioner 10. The main structure 500 and other components of the air conditioner 10 are mounted in the accommodating cavity 112 of the housing 100. The housing 100 can protect other components of the air conditioner 10, reduce the risk of external impurities entering the accommodating cavity 112, and protect other internal structures. Placing all other components in the housing 100 can make the air conditioner 10 form a whole, which can facilitate the installation and transportation of the air conditioner 10.

[0066] The main structure 500 may include structures such as a fan assembly 520 , an air duct assembly 510 and a heat exchanger 530 , which can realize the cooling and heating functions of the air conditioner 10 .

[0067] like Figure 4 and Figure 5As shown, the entire air conditioner 10 is installed in the ceiling 21, and an air outlet 22 connected to the air outlet 114 and a return air outlet connected to the air inlet are provided on the ceiling 21. The indoor air passes through the return air outlet and then enters the accommodating cavity 112 through the air inlet. After heat exchange in the heat exchanger 530, the air is blown into the room through the air outlet 114 and the air outlet 22.

[0068] In order to allow the wind after heat exchange to be blown into the room as quickly as possible, the air outlet 114 and the blowing outlet 22 are basically separated by a very small distance, so that the air outlet 114 and the blowing outlet 22 can basically be overlapped. It can be considered that the air outlet 114 is set at the blowing outlet 22, that is, set in the area of ​​the blowing outlet 22.

[0069] It should be noted that the fan assembly 520 can drive the air flow to move, so that the air flow enters the air outlet 114 through the air outlet channel 512 of the air duct assembly 510, and is finally discharged into the room from the air outlet 22. This part is common knowledge in the field and will not be elaborated on.

[0070] It should be noted that the air conditioner 10 includes an indoor unit and an outdoor unit. The indoor unit is installed indoors, and the outdoor unit is installed indoors. Among them, the air conditioner 10 is installed in the ceiling 21, which means that the indoor unit of the air conditioner 10 is installed in the ceiling 21, and it does not mean that both the indoor unit and the outdoor unit are installed in the ceiling 21. This part is common knowledge in the field and will not be repeated here.

[0071] During the operation of the air conditioner 10, there will be a certain temperature difference between the inside of the shell 100 and the indoor temperature. Especially during the cooling process, the wind entering the accommodating chamber 112 from the indoor temperature will produce condensed water during the heat exchange with the heat exchanger 530. In order to prevent the condensed water from blowing into the indoor temperature, a water receiving tray 210 is provided in the accommodating chamber 112 to collect the condensed water and then discharge it.

[0072] It should be noted that the water receiving pan 210 is disposed in the accommodating chamber 112 and is disposed below the main structure 500. The water receiving pan 210 being disposed below the main structure 500 means that the water receiving pan 210 needs to be disposed at least below the heat exchanger 530, and can also be disposed below the heat exchanger 530 and the air duct assembly 510. Of course, the water receiving pan 210 can also be disposed below the entire accommodating chamber 112, that is, all components in the accommodating chamber 112 are disposed above the water receiving pan 210, which is not limited in this application.

[0073] It should be noted that the fan assembly 520 is arranged in the air outlet channel 512 of the air duct assembly 510, which means that the fan assembly 520 is located in the air outlet channel 512 and the fan assembly 520 is connected to the air duct assembly 510, that is, the fan assembly 520 is located in the air outlet channel 512 and is installed on the air duct assembly 510.

[0074] The air duct assembly 510 is detachably connected to the water receiving tray 210, and the fan assembly 520 is installed in the air outlet channel 512 of the air duct assembly 510. In the process of assembling the air conditioner 10, the fan assembly 520 can be first installed on the air duct assembly 510 and connected to the air duct assembly 510 to form a whole, and then the whole formed by connecting the air duct assembly 510 and the fan assembly 520 is installed on the water receiving tray 210. The fan assembly 520 is installed on the air duct assembly 510. During installation, since the air duct assembly 510 has not been installed on the housing 100, the fan assembly 520 will not be interfered by the housing 100 and other components during installation, which can improve the installation efficiency of the fan assembly 520, facilitate the assembly of the air conditioner 10, and help improve the assembly efficiency of the air conditioner 10.

[0075] That is to say, after the present application is designed in this way, when assembling the air conditioner 10, the fan assembly 520 can be installed on the air duct assembly 510 outside the housing 100, so that the fan assembly 520 and the air duct assembly 510 are connected to form a whole. When installed on the housing 100, the fan assembly 520 and the air duct assembly 510 are installed on the water receiving tray 210 as a whole. During the installation process, the fan assembly 520 is installed on the air duct assembly 510 outside the housing 100, and its installation process will not be interfered by the housing 100 and other components on the housing 100, so the fan assembly 520 can be installed on the air duct assembly 510 more conveniently. Furthermore, during the installation of the air duct assembly 510, since the fan assembly 520 has been pre-installed in the air outlet channel 512 of the air duct assembly 510, the fan assembly 520 will not interfere with the shell 100 when the air duct assembly 510 is installed, and will not affect the installation of the air duct assembly 510. When the air duct assembly 510 is installed in the shell 100, the fan assembly 520 is also located in the shell 100.

[0076] The air duct assembly 510 and the water receiving tray 210 can be detached in various ways, such as snap connection, bolt connection, bonding, etc.

[0077] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, one of the water receiving tray 210 and the air duct assembly 510 is provided with a positioning groove 213 , and the other is provided with a positioning portion 514 f , and the positioning portion 514 f is disposed in the positioning groove 213 .

[0078] One of the water receiving tray 210 and the air duct assembly 510 is provided with a positioning groove 213, and the other is provided with a positioning portion 514f, and there are two setting modes. The first setting mode is to set the positioning groove 213 on the water receiving tray 210 and the positioning portion 514f on the air duct assembly 510, and the second setting mode is to set the positioning portion 514f on the water receiving tray 210 and the positioning groove 213 on the air duct assembly 510. Through the setting of the positioning portion 514f and the positioning groove 213, the water receiving tray 210 and the air duct assembly 510 can be positioned and matched together, which helps to quickly align and connect the water receiving tray 210 and the air duct assembly 510.

[0079] It should be noted that the air duct assembly 510 is not only detachable from the water tray 210. In order to ensure the stability of the air duct assembly 510 and the fan assembly 520 installed thereon, in some embodiments, the air duct assembly 510 is also detachably connected to the heat exchanger 530, which may be a bolt connection, a clip connection, etc., which is not limited here.

[0080] like Figure 7 As shown, in some embodiments, the air duct assembly 510 and the heat exchanger 530 are connected together by screws. A through hole is provided on the air duct assembly 510, and a threaded hole is provided on the heat exchanger 530. When the positioning portion 514f is inserted into the positioning groove 213, the through hole and the threaded hole are aligned, and the bolt passes through the through hole and is threadedly connected with the threaded hole, and the air duct assembly 510 and the heat exchanger 530 are detachably connected by the screws.

[0081] like Figure 8 As shown, in some embodiments, the lower end surface of the air duct assembly 510 is provided with a positioning portion 514f, the upper end surface of the water receiving tray 210 is provided with a positioning groove 213, and the positioning portion 514f of the air duct assembly 510 is inserted into the positioning groove 213 from top to bottom.

[0082] like Fig. 9 and Fig.10 As shown, in some embodiments, the positioning groove 213 includes a first groove segment 213a and a second groove segment 213b, the width of the first groove segment 213a is smaller than the width of the second groove segment 213b, and the positioning portion 514f is at least partially disposed in the first groove segment 213a.

[0083] The positioning portion 514f may be partially located in the first slot section 213a, partially located in the second slot section 213b, or may be completely located in the first slot section 213a, and the positioning portion 514f is positioned by the first slot section 213a. After the second slot section 213b is provided, other structures near the positioning portion 514f can be avoided by the second slot section 213b, so that the positioning portion 514f can be smoothly positioned in the first slot section 213a.

[0084] In some embodiments, a guide portion 213 c is disposed in the positioning groove 213 , and the positioning portion 514 f can be slidably matched with the guide portion 213 c , so that the positioning portion 514 f is located in the positioning groove 213 .

[0085] The guide portion 213 c provides guidance for the positioning portion 514 f , so that the positioning portion 514 f can be inserted into the positioning groove 213 more quickly, thereby improving the efficiency of the connection between the positioning portion 514 f and the positioning groove 213 .

[0086] In some embodiments, a plurality of guide portions 213c are arranged at intervals, and the plurality of guide portions 213c provide guidance to the positioning portion 514f at the same time to improve the guiding effect.

[0087] like Fig.10 and Fig.11 As shown, in some embodiments, the air duct assembly 510 is provided with a first connection portion 514z, and the water receiving tray 210 is provided with a second connection portion 213d, and the first connection portion 514z is detachably connected to the second connection portion 213d.

[0088] The first connection portion 514z and the second connection portion 213d are detachably connected, and may be detachably connected by a snap-fitting manner, or may be detachably connected by a fixing structure.

[0089] In some embodiments, a threaded hole may be provided on the second connection portion 213d, and a through hole may be provided on the first connection portion 514z. When the positioning portion 514f is inserted into the positioning groove 213, the through hole and the threaded hole are aligned, and a bolt passes through the through hole and is threadedly connected to the threaded hole, and the first connection portion 514z and the second connection portion 213d are detachably connected by the screw. The number of threaded holes on the first connection portion 514z and the number of through holes on the second connection portion 213d may not be specifically limited.

[0090] In addition, two first connection parts 514z can be set, and the two first connection parts 514z are respectively located on both sides of the air duct assembly 510 in the width direction X of the shell 100. Two second connection parts 213d can also be set, and the two second connection parts 213d are respectively located on both sides of the water receiving tray 210 in the width direction X of the shell 100.

[0091] like Fig.10 As shown, in some embodiments, the second connection portion 213d is disposed in the second slot segment 213b, and when the first connection portion 514z and the second connection portion 213d are connected, a portion of the first connection portion 514z is located in the second slot segment 213b.

[0092] like Fig.11As shown, in some embodiments, the air duct assembly 510 includes a first air duct 513 and a second air duct 514 , and the second air duct 514 is detachably connected to the water receiving tray 210 .

[0093] It should be noted that the first air duct 513 and the second air duct 514 are connected together, and the first air duct 513 and the second air duct 514 can be connected together in an inseparable manner or in a detachable manner, which is not limited in this application. The fan assembly 520 can be installed on the first air duct 513 or on the second air duct 514, which is not limited in this application.

[0094] In some embodiments, the first air duct 513 has a first limiting surface 513b, and the second air duct 514 has a second limiting surface 514b. One of the first limiting surface 513b and the second limiting surface 514b has a card slot 513z, and the other has a card head 514y, and the card head 514y is engaged with the card slot 513z.

[0095] The first limiting surface 513b may be provided with a slot 513z, and the second limiting surface 514b may be provided with a clamping head 514y, or the first limiting surface 513b may be provided with a clamping head 514y, and the second limiting surface 514b may be provided with a slot 513z, which is not limited here, and the first air duct 513 and the second air duct 514 are clamped together by the clamping action of the clamping head 514y and the slot 513z. The structures of the clamping head 514y and the slot 513z are various, which are not limited in this application.

[0096] With such a design, the first air duct 513 and the second air duct 514 can be detachably connected through the first mounting portion 513h and the second mounting portion 514h, and can also be clamped through the clamping groove 513z and the clamping head 514y, thereby improving the stability of the connection between the first air duct 513 and the second air duct 514. In addition, with such a design, the clamping groove 513z and the clamping head 514y can be clamped first, so that the first air duct 513 and the second air duct 514 are positioned together, and then the first mounting portion 513h and the second mounting portion 514h are aligned, so as to facilitate the connection between the first mounting portion 513h and the second mounting portion 514h.

[0097] In some embodiments, along the width direction X of the shell 100, a plurality of slots 513z are arranged at intervals on the first limiting surface 513b of the first air duct 513, and along the width direction X of the shell 100, a number of clamping heads 514y equal to the number of the slots 513z are arranged at intervals on the second limiting surface 514b of the second air duct 514, and the clamping heads 514y and the slots 513 are arranged in a one-to-one correspondence, a threaded hole is arranged on the second mounting portion 514h, and a through hole is arranged on the first mounting portion 513h.

[0098] After such design, when the clamping head 514y of the second air duct 514 is respectively inserted into each clamping slot 513z of the first air duct 513, the second air duct 514 and the first air duct 513 are positioned together, and the threaded hole on the second mounting portion 514h is aligned with the through hole on the first mounting portion 513h, and the first mounting portion 513h and the second mounting portion 514h can be connected by screws. It can be seen that the arrangement of the clamping slot 513z and the clamping head 514y not only helps to strengthen the connection strength between the first air duct 513 and the second air duct 514, but also provides positioning for the first air duct 513 and the second air duct 514, so as to facilitate the alignment and connection of the first mounting portion 513h and the second mounting portion 514h.

[0099] In some embodiments, the first air duct 513 and the second air duct 514 are detachably connected, and the fan assembly 520 is installed on the second air duct 514; the first air duct 513 is arranged close to the air outlet 114 and is detachably connected to the second air duct 514, and the second air duct 514 is detachably connected to the water receiving tray 210.

[0100] With this arrangement, when the fan assembly 520 fails and needs maintenance, the first air duct 513 can be removed from the air outlet 114 first, so that the fan assembly 520 can be exposed from the air outlet 114. Without removing the second air duct 514, the fan assembly 520 can be removed from the air outlet 114, thereby facilitating the maintenance and cleaning of the fan assembly 520.

[0101] Specifically, since the entire air conditioner 10 is arranged in the ceiling 21, when disassembling, the air outlet grille 23 at the air outlet 22 can be removed first, so that the air outlet 114 can be exposed from the air outlet 22, and then the air duct assembly 510 can be exposed from the air outlet 22, and then the first air duct 513 and the second air duct 514 are separated, and the first air duct 513 is removed from the air outlet 114, so that the fan assembly 520 can be exposed from the air outlet 114, thereby facilitating the disassembly, assembly and maintenance of the fan assembly 520.

[0102] Of course, in the case where only the first air duct 513 fails and needs to be repaired or replaced, only the first air duct 513 can be removed from the housing 100, so that the first air duct 513 can be repaired and cleaned.

[0103] The first air duct 513 and the second air duct 514 are sequentially arranged in the thickness direction Y of the housing 100, and the first air duct 513 is arranged close to the air outlet 114. It can be considered that the first air duct 513 is arranged in front of the second air duct 514, and the second air duct 514 is arranged at the rear of the first air duct 513. The disassembly and assembly of the first air duct 513 can be considered as the disassembly and assembly in the thickness direction Y of the housing 100.

[0104] It should be noted that in order to be able to remove the first air duct 513 from the ceiling 21, the size of the first air duct 513 in the height direction Z of the shell 100 needs to be smaller than the size of the blowing port 22 in the height direction Z of the shell 100, and the size of the first air duct 513 in the width direction X of the shell 100 needs to be smaller than the size of the blowing port 22 in the width direction X of the shell 100, so as to facilitate the disassembly and assembly of the first air duct 513.

[0105] Specifically, the maximum dimension of the first air duct 513 in the height direction Z of the housing 100 may be less than or equal to 150 mm, thereby ensuring that the first air duct 513 can be removed from the air outlet 22 .

[0106] In some embodiments, the first air duct 513 has a first volute 513x and a volute tongue 513y, and the second air duct 514 has a second volute 514x. The volute tongue 513y is arranged in the first air duct 512. After the first air duct 513 is separated from the second air duct 514, that is, after the first air duct 513 is disassembled from the whole machine of the air conditioner 10, the volute tongue 513y is also disassembled, which can reduce the interference of the volute tongue 513y on the disassembly of the fan assembly 520, reduce the shielding of the fan assembly 520 by the volute tongue 513y, so that most of the structure of the fan assembly 520 can be exposed from the second air duct 514, which can facilitate the disassembly and assembly of the fan assembly 520.

[0107] Of course, in some other embodiments, the volute tongue 513y may be provided on the second air duct 512, that is, the volute tongue 513y may be provided only on the first air duct, or the volute tongue 513y may be provided on both the first air duct and the second air duct.

[0108] In some embodiments, the first air duct 513 is provided through the air outlet 114, part of the first air duct 513 is provided in the accommodating cavity 112, and part of the first air duct 513 is provided outside the accommodating cavity 112. Part of the first air duct 513 is located in the accommodating cavity 112, and part of the first air duct 513 is located outside the accommodating cavity 112. That is, a part of the first air duct 513 is outside the entire shell 100. If the fan assembly 520 needs to be repaired, the air outlet grille 23 at the air outlet 22 can be removed first, and the first air duct 513 will be exposed. The maintenance personnel can reach into the ceiling 21, hold the part of the first air duct 513 located outside the shell 100, and then remove the first air duct 513 from the ceiling 21. The operation is simple and convenient.

[0109] See also Fig.12 and Fig.13 In some embodiments, the first air duct 513 has a first guide surface 513a that is inclined, and the second air duct 514 has a second guide surface 514a that is inclined, and the first guide surface 513a can be slidably matched with the second guide surface 514a.

[0110] The first guide surface 513a and the second guide surface 514a can be slidably matched. When installing the first air duct 513, the first air duct 513 is first placed at the air outlet 114, and then the first air duct 513 is pushed into the inside of the housing 100, so that the first guide surface 513a slides into the inside of the housing 100 along the extension direction of the second guide surface 514a, thereby guiding the first air duct 513 during the assembly process of the first air duct 513, which can facilitate the assembly of the first air duct 513. In the disassembly process, on the contrary, the maintenance personnel apply force outside the first air duct 513 to pull the first air duct 513 outward, so that the first guide surface 513a slides toward the outside of the housing 100 along the extension direction of the second guide surface 514a, thereby facilitating the disassembly of the first air duct 513.

[0111] As for the position between the first guide surface 513a and the second guide surface 514a, the first guide surface 513a may be arranged above the second guide surface 514a, or the second guide surface 514a may be arranged above the first guide surface 513a. The relative position between the first guide surface 513a and the second guide surface 514a may not be limited as long as it can play a guiding role for the first air duct 513.

[0112] Among them, the first guide surface 513a and the second guide surface 514a are inclined in the thickness direction Y of the shell 100, so that the first guide surface 513a and the second guide surface 514a can guide the first air duct 513 in the thickness direction Y of the shell 100, which can facilitate the disassembly and assembly of the first air duct 513.

[0113] See also Fig.12 and Fig.14 In some embodiments, the first air duct 513 has a first limiting surface 513b, and the second air duct 514 has a second limiting surface 514b, and the first limiting surface 513b can contact the second limiting surface 514b; wherein the first limiting surface 513b and the second limiting surface 514b are set at an angle to the air outlet direction of the air outlet channel 512.

[0114] Among them, the air outlet direction of the air outlet channel is roughly the same as the thickness direction Y of the shell 100, and the first limiting surface 513b and the second limiting surface 514b are set at an angle with the air outlet direction of the air outlet channel, so it can be considered that the first limiting surface 513b and the second limiting surface 514b are set at an angle with the thickness direction Y of the shell 100. That is, the first limiting surface 513b and the second limiting surface 514b are different from the thickness direction Y of the shell 100. Since the first air duct 513 is disassembled and assembled in the thickness direction Y of the shell 100, the first limiting surface 513b and the second limiting surface 514b are different from the thickness direction Y of the shell 100, which can play a limiting role in the process of assembling the first air duct 513, reminding the maintenance personnel whether the first air duct 513 is assembled in place.

[0115] For example, during the assembly of the first air duct 513, the first guide surface 513a can be first brought into contact with the second guide surface 514a, and the first air duct 513 can be pushed inward along the thickness direction Y of the housing 100, so that the first guide surface 513a slides along the second guide surface 514a until the first limiting surface 513b contacts the second limiting surface 514b. When the first limiting surface 513b contacts the second limiting surface 514b, it can be considered that the position of the first air duct 513 is assembled in place. The first air duct 513 can be fixedly connected to the second air duct 514 or the housing 100.

[0116] The shapes of the first limiting surface 513b and the second limiting surface 514b may be regular or irregular. For example, in some embodiments, at least one of the first limiting surface 513b and the second limiting surface 514b may include multiple segments in different directions. For example, the first limiting surface 513b includes multiple segments, as follows:

[0117] See also Fig.15 and Fig.16 , the first limiting surface 513b may include a first limiting section 513c, a second limiting section 513d, a third limiting section 513e and a fourth limiting section 513f, the first limiting section 513c, the second limiting section 513d, the third limiting section 513e and the fourth limiting section 513f are connected in sequence, the first limiting section 513c and the second limiting section 513d are connected at an angle, the second limiting section 513d and the third limiting section 513e are connected at an angle, and the third limiting section 513e and the fourth limiting section 513f are connected at an angle. It can be considered that the two adjacent sections are connected at an angle, that is, the two adjacent sections are in different directions.

[0118] The second limiting surface 514b may include a first section 514c, a second section 514d and a third section 514e, wherein the first section 514c, the second section 514d and the third section 514e are connected in sequence, the first section 514c and the second section 514d are connected at an angle, and the second section 514d and the third section 514e are connected at an angle. It can be considered that the two adjacent sections are connected at an angle, that is, the two adjacent sections are in different directions.

[0119] During assembly, the first limiting section 513c is fitted with the first section 514c, the second limiting section 513d is fitted with the second section 514d, and the third limiting section 513e is fitted with the third section 514e. Taking the first limiting section 513c and the second limiting section 513d as an example, since the first limiting section 513c and the second limiting section 513d have different directions, the first limiting section 513c and the second limiting section 513d have different directions, during assembly, the first limiting section 513c needs to be fitted with the first section 514c, the second limiting section 513d needs to be fitted with the second section 514d, and the third limiting section 513e needs to be fitted with the third section 514e, only then can it be said that the first air duct 513 and the second air duct 514 are assembled in place, which can improve the positioning accuracy of the first air duct 513 and the second air duct 514 during the assembly process.

[0120] In addition, the fourth limiting section 513f overlaps the side wall of the second air duct 514. When the first air duct 513 is connected to the second air duct 514, it is completely covered by the second air duct 514, that is, it can be considered that part of the second air duct 514 is located in the first air duct 513, so that the wind after heat exchange by the heat exchanger 530 is blown from the second air duct 514 to the first air duct 513, and then blown out from the air outlet 114, which can reduce the amount of air leaked from the connection between the first air duct 513 and the second air duct 514, thereby reducing the loss of air volume as much as possible, and improving the air output of the entire air conditioner 10.

[0121] The second limiting section 513d, the third limiting section 513e and the fourth limiting section 513f may be two in number respectively, and the two parts are symmetrically arranged on both sides of the first limiting section 513c.

[0122] In some embodiments, a sealing layer is disposed between the first limiting surface 513b and the second limiting surface 514b, and the sealing layer abuts against the first limiting surface 513b and the second limiting surface 514b.

[0123] Among them, the first limiting surface 513b is arranged along the width direction X of the housing 100, and the second limiting surface 514b is also arranged along the width direction X of the housing 100. Since the entire air conditioner 10 is in a long strip shape, the lengths of the first limiting surface 513b and the second limiting surface 514b are relatively long, and it can be considered that the lengths of the first limiting surface 513b and the second limiting surface 514b in the width direction X of the housing 100 are almost the same as the length of the air outlet 114 in the width direction X of the housing 100. That is, during the blowing process of the fan assembly 520, the first limiting surface 513b and the second limiting surface 514b almost cover the path of the air outlet channel 512. In order to improve the air outlet volume and air outlet effect of the air duct assembly 510, it is necessary to seal the gap between the first limiting surface 513b and the second limiting surface 514b to avoid air leakage.

[0124] Since a sealing layer is provided between the first limiting surface 513b and the second limiting surface 514b to seal the gap between the first limiting surface 513b and the second limiting surface 514b, air leakage at the connection position between the first air duct 513 and the second air duct 514 is reduced.

[0125] It should be noted that the first limiting surface 513b and the second limiting surface 514b can be all positions where the first air duct 513 contacts the outermost circle of the second air duct 514, that is, a sealing layer can be set at all contact positions of the outermost circles of the first air duct 513 and the second air duct 514, thereby reducing air leakage at the connection between the first air duct 513 and the second air duct 514, thereby reducing the loss of air volume.

[0126] Specifically, the sealing layer can be installed on the first limiting surface 513b or on the second limiting surface 514b, or the sealing layer can be installed neither on the first limiting surface 513b nor on the second limiting surface 514b, as long as the sealing layer is arranged between the first limiting surface 513b and the second limiting surface 514b.

[0127] like Fig.11 , Fig.17 and Fig.18 As shown, in some embodiments, the first air duct 513 is provided with a first mounting portion 513h, and the second air duct 514 is provided with a second mounting portion 514h, and the first mounting portion 513h and the second mounting portion 514h are detachably connected to make the first air duct 513 and the second air duct 514 detachably connected.

[0128] The first mounting portion 513h and the second mounting portion 514h are detachably connected, and may be detachably connected by a snap connection, or may be detachably connected by a fixing structure. In some embodiments, a threaded hole may be provided on the second mounting portion 514h, and a through hole may be provided on the first mounting portion 513h, and the first mounting portion 513h and the second mounting portion 514h may be detachably connected by screws. The number of threaded holes on the second mounting portion 514h and the number of through holes on the first mounting portion 513h may not be specifically limited.

[0129] In addition, two first mounting portions 513h may be provided, and the two first mounting portions 513h are respectively located on both sides of the first air duct 513 in the width direction X of the shell 100, and two second mounting portions 514h may also be provided, and the two second mounting portions 514h are respectively located on both sides of the second air duct 514 in the width direction X of the shell 100.

[0130] In some embodiments, the shell 100 also has an inspection port 116 arranged side by side with the air outlet 114, and the air conditioner 10 also includes an inspection panel 220, which can open or close the inspection port 116. When the inspection panel 220 opens the inspection port 116, the first mounting portion 513h can be exposed at the inspection port 116.

[0131] Since the first air duct 513 is arranged closer to the air outlet 114 than the second air duct 514, in the first mounting portion 513h and the second mounting portion 514h, the first mounting portion 513h is arranged closer to the air outlet 114, that is, in the thickness direction Y of the shell 100, the first mounting portion 513h is located in front of the second mounting portion 514h, and in the thickness direction Y of the shell 100, it can be considered that the first mounting portion 513h and the second mounting portion 514h are overlapped, and the first mounting portion 513h is exposed at the inspection port 116, and the fixing structures on the first mounting portion 513h and the second mounting portion 514h can be disassembled to separate the first mounting portion 513h from the second mounting portion 514h.

[0132] In some embodiments, the shell 100 also has an installation opening 118 arranged side by side with the air outlet 114, and the air conditioner 10 also includes a mounting plate 240, which can open or close the installation opening 118. When the mounting plate 240 opens the installation opening 118, the first mounting portion 513h can be exposed at the installation opening 118.

[0133] Similarly, since the first air duct 513 is arranged closer to the air outlet 114 than the second air duct 514, in the first mounting portion 513h and the second mounting portion 514h, the first mounting portion 513h is arranged closer to the air outlet 114, that is, in the thickness direction Y of the shell 100, the first mounting portion 513h is located in front of the second mounting portion 514h, and in the thickness direction Y of the shell 100, it can be considered that the first mounting portion 513h and the second mounting portion 514h are overlapped, and the first mounting portion 513h is exposed at the mounting port 118, and the fixing structure on the first mounting portion 513h and the second mounting portion 514h can be disassembled to separate the first mounting portion 513h from the second mounting portion 514h.

[0134] Since there are two first mounting parts 513h and second mounting parts 514h respectively and are located on both sides of the width direction X of the shell 100, the mounting port 118 and the inspection port 116 are respectively located on both sides of the air outlet 114 in the width direction X of the shell 100, that is, the inspection port 116, the air outlet 114 and the mounting port 118 are all located in the same plane of the shell 100. The air conditioner 10 may further include a mounting plate 240, which can open or close the mounting port 118.

[0135] The installation opening 118 and the inspection opening 116 have the same function, and the installation plate 240 and the inspection plate 220 have the same function.

[0136] If it is necessary to remove the first air duct 513, the mounting plate 240 and the inspection plate 220 can be removed first, so that the two first mounting parts 513h can be exposed from the inspection port 116 and the mounting port 118 respectively. The maintenance personnel put their hands into the shell 100, remove the fixing structure of the first mounting part 513h and the second mounting part 514h, and then place their hands on the part of the first air duct 513 outside the shell 100, pull the entire first air duct 513 outward, and the first air duct 513 can be removed from the ceiling 21.

[0137] The installation process is the opposite, first push the first air duct 513 into the housing 100, so that the first limiting section 513c fits with the first section 514c, the second limiting section 513d fits with the second section 514d, and the third limiting section 513e fits with the third section 514e, and then the first mounting portion 513h and the second mounting portion 514h are fixedly connected by a fixing structure, and after the installation is completed, the inspection plate 220 is installed in the inspection port 116, and the mounting plate 240 is installed in the mounting port 118, and the first air duct 513 is installed. Finally, the air outlet grille 23 at the air outlet 22 is installed in the air outlet 22.

[0138] See also Fig.19In some embodiments, the fan assembly 520 includes a wind wheel 521 and a drive motor 522, the drive motor 522 is transmission-connected to the wind wheel 521, the electric control assembly 300 and the drive motor 522 are respectively located at two ends of the wind wheel 521, the drive motor 522 is electrically connected to the electric control assembly 300 through a connecting wire, and the connecting wire is fixed to the second air duct 514.

[0139] Among them, the wind wheel 521 is arranged in the air outlet channel 512, the driving motor 522 is arranged in the shell 100 and outside the air outlet channel 512, and the electric control component 300 is also arranged outside the air outlet channel 512. The length of the air duct in the width direction X of the shell 100 will be relatively long and will run through the entire air outlet channel 512. The electric control component 300 and the driving motor 522 are respectively located at both ends of the wind wheel 521, so that the connecting line connecting the driving motor 522 and the electric control component 300 will be relatively long. In order to facilitate the routing of the connecting line, the connecting line can be routed from the outside of the second air duct 514 and fixed to the second air duct 514. The connecting line can be reasonably installed and fixed, and the connection line cannot be fixed to the maximum extent to avoid interfering with the work of other components.

[0140] In some embodiments, the fan assembly 520 includes a wind wheel 521, a drive motor 522 and a motor cover 523. The drive motor 522 is transmission-connected to the wind wheel 521. The wind wheel 521 and the drive motor 522 are detachably installed in the second air duct 514. The motor cover 523 is covered on the drive motor 522 and is detachably connected to the second air duct 514.

[0141] The motor cover 523 is arranged outside the air outlet channel 512 and covers the drive motor 522, which can play a role in installing and fixing the drive motor 522. The motor cover 523 is detachably connected to the second air duct 514. After the first air duct 513 is removed from the shell 100, the entire fan assembly 520 is exposed. The motor cover 523 and the second air duct 514 can be separated first, so that the wind wheel 521 and the motor of the drive motor 522 can move relative to the second air duct 514, and then the wind wheel 521 and the drive motor 522 can be removed from the second air duct 514.

[0142] That is to say, if the fan assembly 520 needs to be disassembled, the first air duct 513 needs to be removed from the shell 100 first, so that the entire fan assembly 520 can be exposed from the air outlet 22, and then the motor cover 523 is removed, and finally the wind wheel 521 and the drive motor 522 are removed.

[0143] In some embodiments, the diameter of the wind wheel 521 is smaller than the diameter of the inner cavity of the second air duct 514 , and the diameter of the wind wheel 521 is smaller than the minimum width of the opening of the second air duct 514 .

[0144] The wind wheel 521 is roughly circular, and the wind wheel 521 is installed in the second air duct 514. In order to reduce the volume of the second air duct 514 as much as possible while installing the wind wheel 521, the internal cavity of the second air duct 514 can be set to be circular or semicircular. The diameter of the wind wheel 521 is smaller than the diameter of the internal cavity of the second air duct 514, so that the second wind wheel 521 can rotate inside the second air duct 514 to avoid interference with the second air duct 514.

[0145] The opening of the second air duct 514 refers to the joint between the second air duct 514 and the first air duct 513. The diameter of the wind wheel 521 is smaller than the minimum width of the opening of the second air duct 514, so that after the first air duct 513 is disassembled, the wind wheel 521 can be disassembled from the inside of the second air duct 514 through the joint.

[0146] As for the size relationship between the diameter of the inner cavity of the second air duct 514 and the minimum width at the opening of the second air duct 514 , the diameter of the inner cavity of the second air duct 514 may be greater than the minimum width at the opening of the second air duct 514 .

[0147] See also Fig. 20 and Fig.21 As for the detachable connection between the motor cover 523 and the second air duct 514, a clamping groove 514g can be provided on the second air duct 514, and a clamping portion 524 can be provided on the motor cover 523, and the clamping portion 524 can be clamped into the clamping groove 514g, and the motor cover 523 can be positioned on the second air duct 514 through the cooperation between the clamping portion 524 and the clamping groove 514g. A through hole can also be provided on the motor cover 523, and a threaded hole can be provided on the second air duct 514, and the motor cover 523 and the second air duct 514 can be fixedly connected by a fixing member such as a screw.

[0148] In some embodiments, the shell 100 also has an installation opening 118 arranged side by side with the air outlet 114, and the air conditioner 10 also includes a mounting plate 240, which can open or close the installation opening 118. When the mounting plate 240 opens the installation opening 118, the motor cover 523 can be exposed at the installation opening 118.

[0149] The installation opening 118 and the inspection opening 116 are respectively located on both sides of the air outlet 114, and the motor cover 523 is provided on the driving motor 522, that is, the motor cover 523 and the electronic control component 300 are respectively located on both sides of the wind wheel 521. When the installation opening 118 is opened by the installation plate 240, the motor cover 523 can be exposed at the installation opening 118, which can be convenient for maintenance personnel to operate and can facilitate the disassembly and assembly of the fan assembly 520.

[0150] That is to say, if it is necessary to disassemble the fan assembly 520, first remove the air outlet grille 23 at the air outlet 22, then open the inspection panel 220 and the mounting plate 240, and separate the first fixing portion 340 and the second fixing portion 212 at both ends respectively, so that the first air duct 513 and the second air duct 514 are separated, and the maintenance personnel hold the part of the first air duct 513 outside the shell 100, and remove the first air duct 513 completely from the shell 100. At this time, the fan assembly 520 is exposed, and then separate the motor cover 523 and the second air duct 514. After removing the motor cover 523, finally remove the wind wheel 521 and the drive motor 522.

[0151] The installation process is the opposite. First, the wind wheel 521 and the driving motor 522 are placed in the second air duct 514, and then the motor cover 523 is covered on the driving motor 522. The clamping part 524 is clamped into the clamping groove 514g. The motor cover 523 is positioned on the second air duct 514 through the cooperation of the clamping part 524 and the clamping groove 514g. Then, the motor cover 523 and the second air duct 514 are fixedly connected, and the fan assembly 520 is installed. Then place the first air duct 513 in the housing 100 so that the first guide surface 513a can slide along the second guide surface 514a until the first limit section 513c fits with the first section 514c, the second limit section 513d fits with the second section 514d, and the third limit section 513e fits with the third section 514e, and then the first fixing portion 340 and the second fixing portion 212 are fixedly connected by the fixing structure. After the installation is completed, the inspection plate 220 is installed on the inspection opening 116, and the mounting plate 240 is installed on the mounting opening 118, and the first air duct 513 is installed. Finally, the air outlet grille 23 at the air outlet 22 is installed on the air outlet 22.

[0152] The above structure illustrates how to install and disassemble the air duct assembly 510 and the fan assembly 520 . The following will introduce how to install, disassemble and arrange the electronic control assembly 300 and the water pump assembly 400 in the housing 100 .

[0153] See also Fig. 22 and Fig.23 In some other embodiments of the present application, the air conditioner 10 includes: a shell 100, a main structure 500, an electronic control component 300 and an inspection panel 220, the shell 100 has a accommodating cavity 112 and an air outlet 114 and an inspection port 116 connected to the accommodating cavity 112, and the air outlet 114 and the inspection port 116 are located on the same side of the shell 100; the main structure 500 is arranged in the accommodating cavity 112 and is connected to the air outlet 114; the inspection panel 220 is installed in the shell 100 and can open or close the inspection port 116; the electronic control component 300 is detachably arranged in the accommodating cavity 112, and can be exposed at the inspection port 116 when the inspection panel 220 opens the inspection port 116.

[0154] In some embodiments, the inspection port 116 and the air outlet 114 are arranged on the same side of the housing 100, that is, the inspection port 116 and the air outlet 114 are arranged on the same plane of the housing 100, and it can be considered that the inspection port 116 is also arranged at the air outlet 22, and is arranged in the area of ​​the air outlet 22. The inspection plate 220 covers the inspection port 116, and the inspection plate 220 is also arranged in the area of ​​the air outlet 22.

[0155] Among them, when the inspection panel 220 opens the inspection port 116, the electric control component 300 can be exposed from the inspection port 116, which means that when the inspection port 116 is opened, there is no other structure blocking the electric control component 300, and the electric control component 300 can be directly exposed from the inspection port 116. The user can directly remove the electric control component 300 from the shell 100 through the inspection port 116.

[0156] When the electric control component 300 fails and needs maintenance, the air outlet grille 23 at the air outlet 22 can be removed first, so that the plane of the shell 100 where the inspection port 116 and the air outlet 114 are provided is exposed, and then the inspection port 116 is opened to expose the electric control component 300 through the inspection port 116 and the air outlet 22. The electric control component 300 can then be directly inspected or replaced. The operation is simple and convenient, and there is no need to remove installation structures such as the ceiling 21, thereby reducing the maintenance cost of the electric control component 300.

[0157] It should be noted that the air conditioner 10 includes an indoor unit and an outdoor unit. The indoor unit is installed indoors, and the outdoor unit is installed indoors. Among them, the air conditioner 10 is installed in the ceiling 21, which means that the indoor unit of the air conditioner 10 is installed in the ceiling 21, and it does not mean that both the indoor unit and the outdoor unit are installed in the ceiling 21. This part is common knowledge in the field and will not be repeated here.

[0158] In some embodiments, the access panel 220 is detachably connected to the housing 100. Since the air conditioner 10 is installed in the ceiling 21, in order to reduce the occupied space and the area of ​​the box opening 315 of the air outlet 22 as much as possible, the width of the air conditioner 10 is slightly smaller than the width of the air outlet 22. The access panel 220 is detachably connected to the housing 100. When inspecting the electric control component 300, the access panel 220 can be directly disassembled and connected, so that the access panel 220 does not occupy the space of the air outlet 22, and the access opening 116 can be fully opened, which is convenient for the inspection of the electric control component 300.

[0159] As for the specific detachable connection method between the inspection plate 220 and the shell 100, connection holes may be respectively provided on the shell 100 and the inspection plate 220, and the shell 100 and the inspection plate 220 may be detachably connected by means of screws, bolts, nuts, etc.

[0160] In addition, in addition to being detachably connected to the shell 100, the inspection panel 220 can also be detachably connected to other structures of the air conditioner 10, for example: it can be detachably connected to the air duct assembly 510, and it can be detachably connected to the water pump assembly 400. The specific detachable method can refer to the detachable connection method between the inspection panel 220 and the shell 100, which will not be repeated here.

[0161] Of course, in addition to this, in some other embodiments, the inspection panel 220 may also be rotatably connected, slidably connected, etc. to the housing 100 , so as to realize the function of opening and closing the inspection port 116 .

[0162] See also Fig.24 In some embodiments, the water receiving tray 210 is located below the main structure 500 , and the electronic control component 300 is installed on the water receiving tray 210 and is detachably connected to the water receiving tray 210 .

[0163] The water receiving tray 210 is arranged below the main structure 500. The water receiving tray 210 needs to be arranged at least below the heat exchanger 530, and can also be arranged below the heat exchanger 530 and the air duct assembly 510. Of course, the water receiving tray 210 can also be arranged below the entire accommodating cavity 112, that is, all components in the accommodating cavity 112 are arranged above the water receiving tray 210.

[0164] Since the water tray 210 is arranged below the main structure 500, the electronic control component 300 can be installed on the water tray 210 without having to separately set up a mounting structure for the electronic control component 300. The electronic control component 300 can be installed using the structure of the air conditioner 10 itself, thereby achieving fixed installation of the electronic control component 300.

[0165] See also Fig.25 In some embodiments, the air conditioner 10 further includes a water pump assembly 400 , which is detachably disposed in the accommodating cavity 112 and can be exposed from the inspection opening 116 when the inspection panel 220 opens the inspection opening 116 .

[0166] During the operation of the air conditioner 10, especially during the cooling process, due to the large temperature difference between the indoor air and the heat exchanger 530, condensed water will be generated near the heat exchanger 530 after entering the accommodating chamber 112, and the condensed water will drip onto the water receiving pan 210 below the heat exchanger 530. Due to the limited size of the air conditioner 10, the depth of the water receiving pan 210 will not be set too large, and the condensed water in the water receiving pan 210 needs to be discharged in time. The water pump assembly 400 is arranged in the accommodating chamber 112, mainly used to drain the condensed water in the water receiving pan 210 to prevent the condensed water in the water receiving pan 210 from overflowing excessively.

[0167] The water pump assembly 400 can be exposed at the inspection port 116 when the inspection panel 220 is opened. If the water pump assembly 400 fails and needs to be repaired or replaced, the air outlet grille 23 at the air outlet 22 is first removed so that the plane of the housing 100 where the inspection port 116 and the air outlet 114 are set can be exposed, and then the inspection panel 220 is opened so that the water pump assembly 400 can be exposed through the inspection port 116 and the air outlet 22. The maintenance personnel can reach into the accommodating cavity 112 and remove the water pump assembly 400 from the housing 100. Before removing the water pump assembly 400, it is only necessary to remove the air outlet grille 23 at the air outlet 22 and the inspection panel 220, which is simple and convenient to operate. Furthermore, the inspection port 116 and the air outlet 114 are located on the same side of the housing 100 , that is, on the same plane of the housing 100 , so that after the air outlet grille 23 is disassembled, the inspection plate 220 can be exposed, which can facilitate the operation of maintenance personnel.

[0168] It should be noted that the inspection openings 116 corresponding to the water pump assembly 400 and the electric control assembly 300 may be the same inspection opening 116 or different inspection openings 116. Specifically, the water pump assembly 400 and the electric control assembly 300 may be arranged at the same position of the accommodating chamber 112, and the inspection opening 116 may be arranged larger to cover both the water pump assembly 400 and the electric control assembly 300. Alternatively, the water pump assembly 400 and the electric control assembly 300 may be arranged at different positions of the accommodating chamber 112, and two inspection openings 116 and two inspection panels 220 may be arranged respectively, one inspection opening 116 corresponding to the electric control assembly 300, and the other inspection opening 116 corresponding to the water pump assembly 400.

[0169] In some embodiments, the electronic control assembly 300 is disposed between the water pump assembly 400 and the main structure 500 .

[0170] The electric control assembly 300 needs to be electrically connected to the fan assembly 520 and the water pump assembly 400 at the same time. If the water pump assembly 400 is arranged between the electric control assembly 300 and the main structure 500, the wiring of the main structure 500 needs to pass over the water pump assembly 400, which increases the length of the connecting line of the main structure 500. Similarly, if the main structure 500 is arranged between the water pump assembly 400 and the electric control assembly 300, the wiring between the water pump assembly 400 needs to pass over the main structure 500, which also increases the length of the connecting line of the water pump assembly 400. The electric control assembly 300 is arranged between the main structure 500 and the water pump assembly 400, that is, the electric control assembly 300 is arranged between the main structure 500 and the water pump assembly 400, so that the length of the connecting line can be as short as possible, thereby reducing the length of the connecting line and facilitating the arrangement and fixation of the connecting line.
