[0075] With the development of society, electrical appliances such as air conditioners are gradually widely used. In order to reduce the occupied space during installation, the air conditioner can be installed in the ceiling, that is, the indoor unit of the air conditioner can be installed in the ceiling. This installation method basically only leaves two box openings, the air outlet and the return air outlet, to communicate with the indoor space. In the related technology, the air duct assembly and the fan assembly are installed inside the indoor unit. If a fault occurs, the ceiling needs to be removed before maintenance. This maintenance method leads to a high maintenance cost for the air conditioner. The air conditioner provided in the embodiment of the present application can improve the above problems. The air conditioner provided in the embodiment of the present application can repair the fan assembly and the air duct assembly without destroying the installation structure of the air conditioner. The operation is simple and convenient, which reduces the maintenance cost.

[0076] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0077] 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 maintenance of the fan assembly 520, is simple and convenient to operate, and reduces the maintenance cost of the fan assembly 520.

[0078] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the air conditioner 10 includes: a shell 100, 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 air duct assembly 510 includes a first air duct 513 and a second air duct 514 forming an air outlet channel 512, the second air duct 514 is arranged in the accommodating chamber 112, and the fan assembly 520 is arranged in the air outlet channel 512 and is detachably connected to at least one of the first air duct 513, the second air duct 514 and the shell 100; wherein, in the first air duct 513 and the second air duct 514, the first air duct 513 is arranged close to the air outlet 114, and the first air duct 513 is detachably connected to the shell 100 and / or the second air duct 514.

[0079] The fan assembly 520 is detachably connected to at least one of the first air duct 513, the second air duct 514 and the housing 100, and has multiple connection modes. In the first case, the fan assembly 520 is detachably connected to only one of the first air duct 513, the second air duct 514 and the housing 100. For example, the fan assembly 520 may be detachably connected to only the first air duct 513, or the fan assembly 520 may be detachably connected to only the second air duct 514, or the fan assembly 520 may be detachably connected to only the housing 100.

[0080] In the second case, the fan assembly 520 is detachably connected to two of the first air duct 513, the second air duct 514 and the housing 100. For example, the fan assembly 520 may be detachably connected to the first air duct 513 and the second air duct 514, or the fan assembly 520 may be detachably connected to the first air duct 513 and the housing 100, or the fan assembly 520 may be detachably connected to the second air duct 514 and the housing 100.

[0081] In the third case, the fan assembly 520 is detachably connected to the first air duct 513, the second air duct 514 and the housing 100. The specific detachable connection method of the fan assembly 520 is not specifically limited.

[0082] The air outlet channel 512 is formed by a first air duct 513 and a second air duct 514, and the fan assembly 520 is arranged in the air outlet channel 512. The fan assembly 520 can be arranged in the first air duct 513, or in the second air duct 514, or in both the first air duct 513 and the second air duct 514.

[0083] The first air duct 513 is detachably connected to the shell 100 and / or the second air duct 514. The first air duct 513 may be only connected to the shell 100, or only detachably connected to the second air duct 514, or the first air duct 513 may be detachably connected to both the second air duct 514 and the shell 100.

[0084] 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 other components of the air conditioner 10 are mounted in the accommodating cavity 112 of the housing 100. The housing 100 can protect the 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.

[0085] The main structure 500 may include a fan assembly 520, an air duct assembly 510, and a heat exchanger 530, etc., which can realize the cooling and heating functions of the air conditioner 10. The entire air conditioner 10 is installed on the ceiling 21 (such as Figure 4 and Figure 5 As shown in the figure, an air outlet 22 connected to the air outlet 114 and an air return 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.

[0086] 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.

[0087] 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.

[0088] The first air duct 513 is arranged close to the air outlet 114 and is detachably connected to the shell 100 and / or the second air duct 514. When the fan assembly 520 fails and needs maintenance, the first air duct 513 can be removed from the air outlet 114 first, and then the fan assembly 520 can be removed from the air outlet channel 512, so that the fan assembly 520 can be removed from the air outlet 114, which can facilitate the maintenance and cleaning of the fan assembly 520.

[0089] 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 first air duct 513 can be exposed from the air outlet 22, and then the first air duct 513 and the second air duct 514 and / or the shell 100 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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 .

[0094] 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 513, and 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.

[0095] Of course, in some other embodiments, the volute tongue 513y may be provided on the second air duct 514, 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.

[0096] 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.

[0097] See also Figure 6 and Figure 7 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] See also Figure 6 and Figure 8 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.

[0102] Among them, the air outlet direction of the air outlet channel 512 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 512, 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.

[0103] 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.

[0104] 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:

[0105] See also Fig. 9 and Fig.10 , 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] In some embodiments, a sealing layer is disposed between the first limiting surface 513b and the second limiting surface 514b. The sealing layer is disposed between the first limiting surface 513b and the second limiting surface 514b and abuts against the first limiting surface 513b and the second limiting surface 514b.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] See also Fig.11 and Fig.12 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 is detachably connected to the second mounting portion 514h.

[0116] 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.

[0117] 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.

[0118] like Fig.13 As shown, 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 card-engaged with the card slot 513z.

[0119] 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.

[0120] 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.

[0121] For example Fig.13As shown, 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, 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.

[0122] 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. 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] The installation process is the opposite. First, push the first air duct 513 into the housing 100, so that 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. Then, the first mounting portion 513h and the second mounting portion 514h are fixedly connected by a fixing structure. After the installation is completed, the inspection plate 220 is installed on the inspection port 116, and the mounting plate 240 is installed on the mounting port 118. 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. The above details how to install and remove the first air duct 513 in the housing 100. The following will introduce how to install and remove the fan assembly 520.

[0130] See also Fig.14In 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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 .

[0136] 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.

[0137] 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.

[0138] 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 .

[0139] See also Fig.15 and Fig.16 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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 .

[0145] See also Fig.17 and Fig.18 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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 .

[0154] See also Fig.19 In some embodiments, the air conditioner 10 further includes a water receiving tray 210 , which is disposed in the accommodating cavity 112 and 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 .

[0155] 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 set in the accommodating chamber 112 to collect the condensed water and then discharge it.

[0156] 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.

[0157] 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.

[0158] See also Fig. 20 In some embodiments, the electric control assembly 300 includes an electric control box 310 and a circuit board 320. The electric control box 310 has an installation cavity 330. The circuit board 320 is installed in the installation cavity 330 and is detachably connected to the electric control box 310. The electric control box 310 is detachably connected to the water receiving tray 210.

[0159] The circuit board 320 is disposed in the installation cavity 330 and is detachably connected to the electric control box 310. The electric control box 310 is also detachably connected to the water receiving tray 210. That is, during maintenance, the electric control box 310 and the circuit board 320 can be disassembled as a whole before maintenance or replacement. Alternatively, only the circuit board 320 can be disassembled for maintenance or replacement. Whether to disassemble the entire unit or only the circuit board 320 can be selected according to the specific replacement structure, and the operation is flexible and convenient.

[0160] In some embodiments, the electronic control component 300 includes a box body 312, a box cover 314 and a circuit board 320. The box body 312 has a box opening 315. The box cover 314 is detachably connected to the box body 312 and can open or close the box opening 315. The circuit board 320 is detachably disposed in the box body 312.

[0161] Among them, the box body 312 and the box cover 314 constitute the electric control box 310, and the box body 312 and the box cover 314 form an installation cavity 330. The circuit board 320 is arranged in the box body 312, that is, the circuit board 320 is arranged in the installation cavity 330 and is detachably connected to the box body 312. The box body 312 is also detachably connected to the water receiving tray 210, that is, when repairing, the electric control box 310 and the circuit board 320 can be disassembled as a whole, and then repaired or replaced. It is also possible to disassemble only the circuit board 320 for repair or replacement. It can be selected whether to disassemble the entire or only the circuit board 320 according to the specific replacement structure, and the operation is flexible and convenient.

[0162] In some embodiments, the electric control component 300 further includes a terminal cover 317, which is connected to the box cover 314. The terminal cover 317 is mainly used to cover the outside of the connecting wires or the connecting terminals to protect the connecting wires.

[0163] In some embodiments, a fixing groove 318 is disposed in the box body 312 . The fixing groove 318 extends in a thickness direction Y of the housing 100 in a direction away from the inspection opening 116 . The circuit board 320 is installed in the fixing groove 318 .

[0164] The housing 100 is roughly a rectangular parallelepiped, and has three directions: width direction X, thickness direction Y, and height direction Z. The height direction Z refers to the vertical direction of the housing 100 in the installed and used state, the width direction X indicates the direction in which the length of the housing 100 is the longest, and the thickness direction Y is a direction perpendicular to both the width direction X and the height direction Z, and is also a direction away from the air outlet 114. For the convenience of description, the orientations of the two ends of the width direction X of the housing 100 are left and right, the orientations of the two ends of the height direction Z are up and down, and the orientations of the two ends of the thickness direction Y are front and back.

[0165] The fixing groove 318 extends in the thickness direction Y of the shell 100 in the direction away from the inspection port 116, which means that the extension direction of the fixing groove 318 is consistent with the thickness direction Y of the shell 100, that is, the fixing groove 318 extends in the direction away from the air outlet 114, and the extension direction of the fixing groove 318 is roughly the same as the extension direction of the limiting groove 214. The circuit board 320 is inserted into the fixing groove 318. If the circuit board 320 needs to be removed, after opening the box cover 314, the circuit board 320 is dragged so that the circuit board 320 can extend the fixing groove 318 and slide out of the box body 312, and then be removed from the electrical control box 310.

[0166] In some embodiments, along the thickness direction Y of the housing 100 , the projections of the box opening 315 and the inspection opening 116 on the inspection plate 220 overlap.

[0167] The projections of the box opening 315 and the inspection opening 116 on the inspection plate 220 at least partially overlap, which means that when the inspection plate 220 opens the inspection opening 116, the box opening 315 overlaps with the inspection opening 116, that is, the box opening 315 is connected to the inspection opening 116. The circuit board 320 can be directly pulled out of the electric control box 310, and only the circuit board 320 can be removed, and the entire electric control assembly 300 does not need to be removed, which is simple and convenient to operate. The maintenance personnel can choose to remove the entire electric control assembly 300 or only the circuit board 320 according to the situation of the electric control assembly 300. The maintenance method is flexible and controllable, which can increase the operability of the maintenance.

[0168] In some embodiments, the box body 312 includes a first box plate 312a, a second box plate 312b and a wiring board 312c, the first box plate 312a and the second box plate 312b are connected and covered outside the wiring board 312c, and the circuit board 320 is detachably arranged in the wiring board 312c. The detachable connection between the first box plate 312a and the second plate can facilitate the assembly and maintenance of the entire electric control component 300.

[0169] The above specifically describes how the circuit board 320 is installed and detachable in the electric control box 310 . The following describes how the electric control box 310 is detachably connected to the water receiving tray 210 .

[0170] See also Fig.21 In some embodiments, the electric control box 310 is provided with a first fixing portion 340, and the water receiving tray 210 is provided with a second fixing portion 212, and the first fixing portion 340 and the second fixing portion 212 are detachably connected. In which, at least one of the first fixing portion 340 and the second fixing portion 212 can be exposed to the inspection opening 116 when the inspection panel 220 opens the inspection opening 116.

[0171] At least one of the first fixing portion 340 and the second fixing portion 212 can be exposed to the inspection opening 116 when the inspection panel 220 opens the inspection opening 116. It is possible that only the first fixing portion 340 is exposed to the inspection opening 116 when the inspection panel 220 opens the inspection opening 116, or only the second fixing portion 212 is exposed to the inspection opening 116 when the inspection panel 220 opens the inspection opening 116. It is also possible that both the first fixing portion 340 and the second fixing portion 212 are exposed to the inspection opening 116 at the same time when the inspection panel 220 opens the inspection opening 116.

[0172] The first fixing part 340 and the second fixing part 212 are detachably connected, and at least one of them can be exposed at the inspection opening 116 when the inspection panel 220 is opened. When the inspection panel 220 opens the inspection opening 116, the first fixing part 340 and the second fixing part 212 can be operated directly to separate the electric control component 300 from the water receiving tray 210, so as to facilitate the disassembly of the electric control component 300.

[0173] Specifically, the first fixing part 340 is arranged between the second fixing part 212 and the inspection plate 220. The first fixing part 340 can be overlapped on the second fixing part 212. Threaded holes can be set on both the first fixing part 340 and the second fixing hole, and the first fixing part 340 and the second fixing part 212 can be detachably connected by screws.

[0174] It is easy to understand that the first fixing portion 340 can be exposed at the inspection opening 116 when the inspection plate 220 opens the inspection opening 116, and the screws fixing the first fixing portion 340 and the second fixing portion 212 can also be exposed at the inspection opening 116. During disassembly and assembly, the inspection plate 220 is first removed to expose the entire electric control component 300, and then the screws are tightened to separate the first fixing portion 340 from the second fixing portion 212, and the electric control box 310 from the water receiving tray 210, so that the electric control component 300 can be disassembled.

[0175] See also Fig. 22 In some embodiments, a limiting groove 214 is provided on the water receiving tray 210, and the electronic control component 300 is installed in the limiting groove 214. Along the thickness direction Y of the shell 100, the projection of the notch 214a of the limiting groove 214 and the inspection port 116 on the inspection plate 220 at least partially overlap.

[0176] The electric control component 300 is installed in the limiting groove 214, and the limiting groove 214 can fix and limit the electric control component 300. The notch 214a of the limiting groove 214 and the projection of the inspection port 116 on the inspection plate 220 at least partially overlap, which means that when the inspection plate 220 opens the inspection port 116, the notch 214a of the limiting groove 214 overlaps with the inspection port 116, that is, the notch 214a of the limiting groove 214 is connected to the inspection port 116. The electric control component 300 can be directly pulled out of the limiting groove 214, and the disassembly and assembly method is simple.

[0177] Specifically, the second fixing portion 212 can be set at the slot 214a of the limiting slot 214. When the electric control component 300 needs to be disassembled, the inspection panel 220 can be opened first (the inspection panel 220 can be removed from the shell 100), and then the screws connecting the first fixing portion 340 and the second fixing portion 212 are screwed to separate the electric control box 310 from the water receiving tray 210, and then the electric control box 310 is pulled outward along the limiting slot 214 until the entire electric control box 310 is detached from the inspection port 116 to the outside of the accommodating cavity 112.

[0178] The installation process is the opposite. First, place the electric control box 310 at the notch 214a of the limiting groove 214, push the electric control box 310 inward until the first fixing part 340 overlaps the second fixing part 212, and then fix the first fixing part 340 and the second fixing part 212 with screws.

[0179] In some embodiments, the water receiving tray 210 is provided with a first water retaining member 215, a third water retaining member 217 and a second water retaining member 216. The first water retaining member 215 and the third water retaining member 217 are arranged opposite to each other. The second water retaining member 216 connects the first water retaining member 215 and the third water retaining member 217. The first water retaining member 215, the third water retaining member 217, the second water retaining member 216 and the water receiving tray 210 form a limiting groove 214, and the second water retaining member 216 is arranged opposite to the groove 214a.

[0180] The electric control box 310 is roughly a rectangular parallelepiped, and the cavity surrounded by the first water retaining member 215, the third water retaining member 217 and the second water retaining member 216 is roughly a rectangular cavity with a notch 130, and the notch 130 is the notch 214a of the limiting groove 214. The limiting groove 214 can play a certain role of limiting and guiding, and can facilitate the installation and fixation of the electric control box 310.

[0181] Since the electrical control box 310 is roughly a rectangular parallelepiped, and the limiting groove 214 formed by the first water retaining member 215, the second water retaining member 216 and the third water retaining member 217 and the water receiving tray 210 is also a rectangular parallelepiped cavity, the shape of the limiting groove 214 is adapted to the shape of the electrical control box 310 and can be slightly larger than the size of the electrical control box 310. When the electrical control box 310 is fixedly installed, the space occupied by the electrical control component 300 can be reduced, and the various components in the accommodating cavity 112 can be compactly arranged, thereby reducing the volume of the air conditioner 10 as much as possible.

[0182] To summarize, in some embodiments of the present application, 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 allow the electric control component 300 to be exposed through the inspection port 116 and the air outlet 22. The entire electric control component 300 or only the circuit board 320 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.

[0183] See also Fig.23 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 .

[0184] 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.

[0185] 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.

[0186] 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.

[0187] See also Fig.24 and Fig.25 As shown, in some embodiments, one side of the housing 100 has a notch 130 communicating with the inspection port 116 , and the water pump assembly 400 includes a bracket 410 and a water pump member 420 mounted on the bracket 410 , and the bracket 410 is detachably mounted on the notch 130 .

[0188] Among them, the bracket 410 can be a plate-like structure, and the bracket 410 can be detachably installed in the gap 130, that is, the bracket 410 can fill the gap 130, so that the bracket 410 can be used as a part of the shell 100. While fixing the water pump part 420, the bracket 410 can be embedded in the gap 130, which can reduce the space occupied by the water pump in the width direction X of the shell 100, so that the various components in the shell 100 are compactly structured, reducing the space occupied by the entire air conditioner 10.

[0189] The gap 130 is connected to the inspection port 116, which means that at least one side of the gap 130 is open, and at least one side has an opening, which is connected to the inspection port 116, so that the bracket 410 can be inserted into or removed from the gap 130. When installing, part of the bracket 410 can be placed into the gap 130 first, and then the entire water pump assembly 400 is pushed inward, so that the water pump assembly 400 can slide inward and be inserted into the gap 130. When disassembling, on the contrary, the entire water pump assembly 400 is pulled outward, so that the bracket 410 slides out of the gap 130, and finally slides out of the inspection port 116 to the outside of the accommodating cavity 112.

[0190] Among them, the bracket 410 is roughly rectangular. In order to adapt to the bracket 410, the shape of the notch 130 is also rectangular. Since the notch 130 is connected to the inspection port 116, the notch 130 has an opening on the side close to the inspection port 116. In addition, the notch 130 has three sides, namely a first side 131 located at the bottom, a vertically arranged second side 132, the second side 132 is arranged opposite to the inspection port 116, and a third side located at the top. The following will specifically introduce how the bracket 410 is assembled and fixed in the notch 130, that is, how to assemble and fix it with the first side 131, the second side 132, etc.

[0191] See also Fig.25 In some embodiments, a first side edge 131 is provided below the notch 130, and the first side edge 131 is provided with a first stop portion 131a protruding toward the accommodating cavity 112 and a second stop portion 131b protruding toward the notch 130, and the second stop portion 131b can be fitted with the bracket 410, and the first stop portion 131a is provided below the bracket 410, and at least one of the first stop portion 131a and the second stop portion 131b is detachably connected to the bracket 410.

[0192] When the air conditioner 10 is in use, the first stopper 131a is convexly disposed toward the accommodating cavity 112, and it can be considered that the first stopper 131a is substantially horizontally disposed. The second stopper 131b is convexly disposed toward the notch 130, and the second stopper 131b is disposed on the first side 131 below the notch 130, and it can be considered that the second stopper 131b is substantially vertically disposed.

[0193] See also Fig.26 , wherein the bracket 410 may include a plate body 412, a first flange 413 and a second flange 415, the plate body 412 is installed in the notch 130, the first flange 413 is connected to the plate body 412 and is arranged at an angle to the plate body 412, the first flange 413 is arranged above the first stopper 131a and fits the first stopper 131a. That is, the first flange 413 is overlapped with the first stopper 131a.

[0194] The second flange 415 is connected to the first flange 413 and is arranged at an angle with the first flange 413. It can be considered that in the width direction X of the housing 100, the second flange 415 and the plate 412 are respectively located on both sides of the first flange 413, so that the shape formed by the plate 412, the first flange 413 and the second flange 415 is roughly Z-shaped. When the air conditioner 10 is in use, the second flange 415 is located below the first flange 413, and the first stopper 131a is provided with a slot 131c, and the second flange 415 is inserted into the slot 131c.

[0195] The first flange 413 and the first stopper 131 a may be merely overlapped, or may be detachably connected while being overlapped, and there is no specific limitation.

[0196] See also Fig. 27 In some embodiments, the notch 130 has a second side 132 disposed opposite to the inspection port 116 , and the second side plate has a third stopper 132 a protruding toward the accommodating cavity 112 , and the third stopper 132 a is detachably connected to the bracket 410 .

[0197] The second side 132 and the inspection opening 116 are spaced apart in the thickness direction Y of the shell 100 , and the inspection opening 116 is located in front of the second side 132 . The bracket 410 also includes a third flange 416 , which is arranged in front of the third stop portion 132 a and overlapped with the third stop portion 132 a .

[0198] The third stopper 132a is provided with a guide groove 132b extending along the height direction Z of the housing 100. When installing the water pump assembly 400, the water pump assembly 400 can be first placed above the notch 130, so that the third flange 416 slides downward along the guide groove 132b until the first flange 413 overlaps the first stopper 131a and the second flange 415 is inserted into the slot 131c, indicating that the water pump assembly 400 is installed in place in the thickness direction Y of the housing 100. Then, the third flange 416 and the third stopper 132a are fixedly connected. As for the detachable fixing method between the third flange 416 and the third stopper 132a, they can be connected by bolts, screws, etc.

[0199] In some embodiments, the third stopper 132a includes a first stopper section 132c and a second stopper section 132d connected at an angle, and the first stopper section 132c is connected to the housing 100 on a side away from the second stopper section 132d, that is, the second stopper section 132d and the notch 130 are respectively located on the left and right sides of the first stopper section 132c. The first stopper section 132c, the second stopper section 132d and the housing 100 form a guide groove 132b. In the process of installing the water pump assembly 400, the entire water pump assembly 400 is first located above the first stopper section 131a so that the third flange 416 can be located in the guide groove 132b, and then the entire water pump assembly 400 is placed downward so that the third flange 416 can slide in the guide groove 132b until the second flange 415 is inserted into the slot 131c, and the second stopper section 131b is located on the left side of the plate body 412. Then, the third flange 416 and the third stopper 132 a are fixedly connected from the front of the water pump assembly 400 , so that the water pump assembly 400 is fixed to the housing 100 .

[0200] That is to say, the guide groove 132b and the second stop portion 131b can limit the water pump assembly 400 on both sides in the width direction X, while the first stop section 132c can limit the water pump in the thickness direction Y, and the first stop portion 131a can limit the water pump in the height direction Z, thereby fixing the water pump assembly 400 in the housing 100.

[0201] Similarly, if the water pump assembly 400 needs to be repaired, the third stopper 132a and the third flange 416 can be separated first, and then the entire water pump assembly 400 can be pulled upward to disengage the second flange 415 from the slot 131c, and can be removed from the inspection port 116 to the outside of the accommodating cavity 112. In other words, when disassembling the water pump assembly 400, only the third flange 416 and the fixing structure in the third stopper 132a need to be disassembled, which is simple and convenient.

[0202] The above is the detachable connection method between the water pump assembly 400 and the housing 100 and how to install and fix the water pump assembly 400. The specific installation position of the water pump assembly 400 in the housing 100 will be introduced below.

[0203] See also Fig.28 In some embodiments, the shell 100 includes a top plate 140, a bottom plate 150, a first side plate assembly 160 and a second side plate assembly 170, the top plate 140 and the bottom plate 150 are respectively connected to the first side plate assembly 160 and the second side plate assembly 170, the top plate 140, the bottom plate 150, the first side plate assembly 160 and the second side plate assembly 170 form a accommodating cavity 112, and the bracket 410 is detachably connected to the first side plate assembly 160.

[0204] The top plate 140 refers to the plate on the top of the air conditioner 10 when in use, and the bottom plate 150 refers to the plate on the bottom of the air conditioner 10 when in use, that is, the top plate 140 is above the bottom plate 150, and the bottom plate 150 is below the top plate 140, and the first side plate assembly 160 and the second side plate assembly 170 are respectively located at the two ends of the top plate 140 and the bottom plate 150.

[0205] Among them, the top plate 140 and the bottom plate 150 have roughly the same shape and size, and the top plate 140 and the bottom plate 150 are roughly long strip-shaped plates. The first side plate assembly 160 and the second side plate assembly 170 are respectively arranged at the two ends of the length direction (referring to the width direction X of the housing 100) of the top plate 140 and the bottom plate 150. The bracket 410 is detachably connected to the first side plate assembly 160, which means that the water pump is installed at one end of the housing 100, and the water receiving tray 210 can be tilted in the direction toward the first side plate assembly 160, that is, for the water receiving tray 210, the height of the end close to the first side plate assembly 160 is lower than the height of the end close to the second side plate assembly 170. The condensed water generated in the heat exchanger 530 can be collected at the lower first side plate assembly 160, so that the water pump assembly 400 can drain the condensed water on the water receiving tray 210 as much as possible, and reduce the overflow of condensed water as much as possible.

[0206] Since the water pump assembly 400 is mainly used to drain the condensed water on the water receiving tray 210, the bracket 410 is detachably connected to the first side panel assembly 160, so that the entire water pump assembly 400 is actually suspended and fixed on the side wall of the shell 100, that is, there is a distance between the water pump assembly 400 and the bottom surface of the water receiving tray 210, which can avoid as much as possible the situation where some components of the water pump assembly 400 are immersed in condensed water and cause damage, and can increase the service life of the water pump assembly 400.

[0207] When the water pump assembly 400 needs to be disassembled, the bracket 410 and the first side plate assembly 160 can be separated, so that the entire water pump assembly 400 can be disassembled from the housing 100 .

[0208] In some embodiments, at least one of the first side panel assembly 160 and the bracket 410 is provided with a first connection portion 163 , and the access panel 220 is provided with a second connection portion 221 , and the first connection portion 163 and the second connection portion 221 are detachably connected.

[0209] Since the notch 130 is connected to the inspection port 116, it means that one surface of the notch 130 is facing the inspection port 116, that is, one side of the bracket 410 can be located in the area of ​​the inspection port 116, that is, the inspection panel 220 can be detachably connected to the first side panel assembly 160 only, or it can be detachably connected to the bracket 410 only, and it can also be detachably connected to both the first side panel assembly 160 and the bracket 410.

[0210] As for the detachable connection method of the first connection part 163 and the second connection part 221 , through holes may be respectively provided on the first connection part 163 and the second connection part 221 , and the first connection part 163 and the second connection part 221 may be detachably connected by screws or bolts.

[0211] In some embodiments, the air conditioner 10 further includes a water receiving pan 210, which is disposed below the main structure 500, and a water pump 420 is disposed above the water receiving pan 210. The water pump 420 is disposed below the water receiving pan 210, so that the water inlet of the water pump 420 can extend into the water receiving pan 210, and can contact the condensed water in the water receiving pan 210, thereby discharging the condensed water to the outside of the housing 100.

[0212] See also Fig.29 Specifically, the water pump component 420 may include a pump body 421, a fixing fixture 422, a drain pipe 423, a water level switch 424 and a detection plate 425. The fixing fixture fixes the pump body 421 on the bracket 410, the drain pipe 423 is connected to the pump body 421, and the water in the water receiving tray 210 is discharged to the outside of the shell 100 through the water inlet of the pump body 421.

[0213] The water level switch 424 is also located above the water receiving tray 210. The water level switch 424 can detect the water level height on the water receiving tray 210 and can timely control the water pump 420 to discharge the condensed water in the water receiving tray 210 to prevent the condensed water in the water receiving tray 210 from overflowing.

[0214] See also Fig.30 In some embodiments, the water pump assembly 400 and the electronic control assembly 300 are arranged on the same side of the main structure 500, and the water pump assembly 400, the electronic control assembly 300 and the main structure 500 are arranged side by side.

[0215] The water pump assembly 400, the electronic control assembly 300 and the main structure 500 are arranged side by side, which means that they are arranged side by side in the width direction X of the shell 100. The electronic control assembly 300 and the water pump assembly 400 can be arranged using the space in the width direction X of the shell 100, and the space in the thickness direction Y or the height direction Z of the shell 100 is not occupied as much as possible, so that the components inside the entire shell 100 can be compactly arranged, thereby reducing the volume of the air conditioner 10.

[0216] Since the water pump assembly 400 and the electric control assembly 300 are located on the same side of the main structure 500, and both the water pump assembly 400 and the electric control assembly 300 can be exposed to the inspection opening 116 when the inspection panel 220 opens the inspection opening 116, that is, the water pump assembly 400 and the electric control assembly 300 can be arranged at the same inspection opening 116, and the electric control assembly 300 and the water pump assembly 400 can be inspected at the same time through the same inspection opening 116.

[0217] In some embodiments, the air conditioner 10 further includes a water receiving tray 210 , which is disposed in the accommodating cavity 112 and below the main structure 500 , and the electronic control component 300 is installed on the water receiving tray 210 .

[0218] 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 set in the accommodating chamber 112 to collect the condensed water and then discharge it.

[0219] 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.

[0220] 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.

[0221] See also Fig.31 In some embodiments, the water receiving tray 210 is provided with at least a first water retaining member 215, a second water retaining member 216 and a third water retaining member 217, and the first water retaining member 215, the second water retaining member 216 and the third water retaining member 217 are connected in sequence to form a limiting groove 214, and the electronic control component 300 is arranged in the limiting groove 214.

[0222] Since the water tray 210 is mainly used to receive condensed water, and the electric control component 300 is internally provided with a large number of electronic components and needs to be waterproofed, the electric control component 300 is disposed on the water tray 210 and needs to be waterproofed to prevent the condensed water in the water tray 210 from invading the electric control component 300 and affecting the operation of the electronic components in the electric control component 300.

[0223] The first water retaining member 215, the second water retaining member 216 and the third water retaining member 217 are all protruded on the water receiving tray 210, so that the first water retaining member 215, the second water retaining member 216 and the third water retaining member 217 are all at a certain height from the bottom surface of the water receiving tray 210, so that the limiting groove 214 formed by the first water retaining member 215, the second water retaining member 216 and the third water retaining member 217 is located above the bottom surface of the water receiving tray 210, rather than inside the water receiving tray 210, so that there is a certain height difference between the opening of the limiting groove 214 and the bottom surface of the water receiving tray 210, which can reduce the risk of condensed water entering the limiting groove 214, that is, condensed water hardly enters the limiting groove 214, and installing the electric control component 300 in the limiting groove 214 can reduce the risk of condensed water entering the wire control component and reduce the possibility of condensed water damaging the electric control component 300, thereby improving the service life of the electric control component 300.

[0224] In some embodiments, the housing 100 further has an air outlet 114 and an inspection port 116 connected to the accommodating cavity 112 . The air outlet 114 and the inspection port 116 are located on the same side of the housing 100 , and the limiting groove 214 is connected to the inspection port 116 .

[0225] 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, so 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, so the inspection plate 220 is also arranged in the area of ​​the air outlet 22.

[0226] Among them, the first water retaining member 215, the second water retaining member 216 and the third water retaining member 217 form a limiting groove 214 with a notch 214a, and the limiting groove 214 is connected with the inspection port 116. It can be considered that the notch 214a of the limiting groove 214 is connected with the inspection port 116. When the inspection port 116 is opened, the electric control component 300 can be directly pulled out from the limiting groove 214, and the disassembly and assembly method is simple.

[0227] Wherein, the first water retaining member 215 and the third water retaining member 217 are respectively connected to the two sides of the second water retaining member 216, that is, the first water retaining member 215 and the third water retaining member 217 form a notch 214a of the limiting groove 214 on one side away from the second water retaining member 216, and the second water retaining member 216 can be considered as the bottom plate 150 of the limiting groove 214. The second water retaining member 216 is arranged opposite to the inspection port 116. The first water retaining member 215 and the third water retaining member 217 are respectively located on both sides of the electric control component 300, one of the first water retaining member 215 and the third water retaining member 217 is arranged between the electric control component 300 and the water pump component 400, and the other is arranged between the electric control component 300 and the main structure 500. The second water retaining member 216 is arranged at the rear side of the electric control component 300.

[0228] That is to say, in some embodiments, in the thickness direction Y of the shell 100, the electronic control component 300 is arranged close to the inspection port 116, that is, in the thickness direction Y of the shell 100, the electronic control component 300 is roughly arranged on the front side of the shell 100, with a certain distance between it and the rear wall of the shell 100.

[0229] The main structure 500 includes an air duct assembly 510, a fan assembly 520 and a heat exchanger 530, wherein the air duct assembly 510 is arranged close to the air outlet 114, the fan assembly 520 is arranged inside the air duct assembly 510, and the heat exchanger 530 is arranged on the side of the air duct assembly 510 away from the air outlet 114. That is, it can be considered that in the thickness direction Y of the shell 100, the air duct assembly 510 and the heat exchanger 530 are arranged in sequence, and the air duct assembly 510 is arranged on the front side of the heat exchanger 530. The inspection port 116 and the air outlet 114 are arranged in the same plane of the housing 100, and the electric control component 300 and the water pump component 400 are arranged near the inspection port 116. It can be considered that in the thickness direction Y of the housing 100, the electric control component 300, the water pump component 400 and the air duct component 510 are arranged at the same position, and the heat exchanger 530 is arranged at the rear side of the electric control component 300, the water pump component 400 and the air duct component 510. In other words, along the width direction X of the housing 100, the projections of the electric control component 300, the water pump component 400 and the air duct component 510 on the housing 100 overlap, and the projections of the electric control component 300 and the heat exchanger 530 on the housing 100 are staggered.

[0230] The first side plate assembly 160 may be provided with a first drain port 161 and a second drain port 162, wherein the first drain port 161 is provided close to the inspection port 116, and the second drain port 162 is provided away from the inspection port 116, that is, in the thickness direction Y of the housing 100, the first drain port 161 is provided at the rear side of the second drain port 162, and the first drain port 161 is provided at the rear side of the water pump assembly 400. Specifically, in the thickness direction Y of the housing 100, the projection of the heat exchanger 530 on the first side plate assembly 160 overlaps with the first drain port 161. The first drain port 161 is communicated with the water receiving pan 210, and the second drain port 162 is communicated with the water pump member 420. It can be considered that the first drain port 161 is a natural drain port, and the second drain port 162 is a forced drain port.

[0231] The second water retaining member 216 is disposed at the rear side of the electric control assembly 300, so that a water guide channel can be formed between the second water retaining member 216 and the rear wall of the water receiving pan 210. After the heat exchanger 530 generates condensed water, the condensed water will fall onto the water receiving pan 210 under the action of gravity. The water receiving pan 210 is tilted toward the direction of the first side plate assembly 160, so that the condensed water will flow to the first drain port 161 through the water guide channel, and be discharged to the outside of the housing 100 through the first drain port 161. If the condensed water cannot be completely discharged through the first drain port 161, the condensed water in the water receiving pan 210 can be forcibly drained through the water pump assembly 400.

[0232] That is to say, along the width direction X of the housing 100, the projections of the electric control component 300 and the heat exchanger 530 on the housing 100 are staggered. A water guide channel is formed between the second water retaining member 216 and the rear wall of the water receiving tray 210, so that the condensed water generated by the heat exchanger 530 can flow to the first drain port 161 through the water guide channel. The electric control component 300 is not arranged on the flow path of the condensed water, which can also reduce the risk of the condensed water entering the limiting groove 214 to a certain extent.

[0233] In some embodiments, the height of the first water retaining member 215, the second water retaining member 216 and the third water retaining member protruding from the water receiving tray 210 is greater than or equal to 25 mm.

[0234] Among them, there is a first drain port 161 that can automatically drain water, so that the condensed water in the water receiving tray 210 will basically not accumulate too much, basically not exceeding 25mm, so the height of the first water retaining member 215, the second water retaining member 216 and the third water retaining member protruding from the water receiving tray 210 are all greater than or equal to 25mm, and basically the condensed water cannot enter the limiting groove 214, which can reduce the risk of condensed water entering the limiting groove 214 to a certain extent, and can reduce the influence of condensed water on the electronic control component 300, thereby increasing the service life of the electronic control component 300.

[0235] Among them, since the second water blocking member 216 is located on the rear side of the electronic control component 300 and mainly plays a role of water blocking, the second water blocking member 216 can be set higher, even higher than the height of the electronic control component 300 in the height direction Z of the shell 100, to prevent condensed water from entering the limiting groove 214.

[0236] In some embodiments, a first water retaining member 215 is disposed between the water pump assembly 400 and the electronic control assembly 300 , and the first water retaining member 215 has a water isolating groove 215 a .

[0237] The first water retaining member 215 is arranged between the water pump assembly 400 and the electric control assembly 300, and the third water retaining member 217 is arranged between the electric control assembly 300 and the main structure 500. During the forced drainage of the water pump assembly 400, water will enter the area of ​​the water pump assembly 400, and the water flow rate will be relatively fast. The temperature of the condensed water is relatively low, which will make the temperature of the gas between the water pump assembly 400 and the electric control assembly 300 relatively low. The electric control assembly 300 will generate heat during operation, so that the temperature difference between the electric control assembly 300 and the surrounding gas is relatively large, which will easily produce condensation. The water barrier 215a is arranged on the first water retaining member 215, which can increase the distance between the water pump assembly 400 and the electric control assembly 300, that is, increase the distance between the electric control assembly 300 and the cold air, thereby reducing the condensation outside the electric control assembly 300, and reducing the condensation entering the electric control assembly 300, affecting the service life of the electric control assembly 300.

[0238] In some embodiments, the width of the water barrier 215a is greater than or equal to 10 mm.

[0239] The width of the water-blocking groove 215a refers to the width in the width direction X of the shell 100. If the width of the water-blocking groove 215a is greater than or equal to 10 mm, it means that the distance between the electronic control component 300 and the water pump component 400 is at least greater than or equal to 10 mm, so that the cold air near the electronic control component 300 and the water pump component 400 have a certain distance, thereby reducing the condensation outside the electronic control component 300 and reducing the condensation entering the electronic control component 300, which affects the service life of the electronic control component 300.

[0240] Specifically, the width of the water isolation groove 215a can be 10 mm, 10.5 mm, 10.9 mm, 11 mm, 11.5 mm, etc., and the specific value is not limited.

[0241] In some embodiments, the air conditioner 10 further includes a heat preservation layer 230, which is disposed in the water isolation groove 215a. In order to further isolate the area between the electric control component 300 and the water pump component 400, the heat preservation layer 230 can be disposed in the water isolation groove 215a, so that the air in the limiting groove 214 can be kept within a certain temperature range, thereby reducing the condensation on the outside of the electric control component 300, reducing the condensation from entering the electric control component 300, and affecting the service life of the electric control component 300.

[0242] Of course, in some other embodiments, the second water retaining member 216 and / or the third water retaining member 217 may also be provided with a water isolation groove 215a, and a heat preservation layer 230 may be provided in the water isolation groove 215a, or the second water retaining member 216 and / or the third water retaining member 217 may only be provided with a water isolation groove 215a without providing a heat preservation layer 230. No specific limitation is made.

[0243] In some embodiments, the electronic control assembly 300 is disposed between the water pump assembly 400 and the main structure 500 .

[0244] 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.

[0245] See also Fig.32 In some embodiments, the electric control assembly 300 includes an electric control box 310, a circuit board 320 (see Fig. 20 ), the terminal seat 316, the circuit board 320 is arranged in the electric control box 310, the water pump assembly 400 is connected to the terminal seat 316 through a connecting wire, and the terminal seat 316 is arranged between the water pump assembly 400 and the inspection port 116.

[0246] The terminal seat 316 is arranged outside the electric control box 310, and is mainly connected to the connection terminal of the water pump assembly 400, so that the water pump assembly 400 can be electrically connected to the electric control assembly 300. The terminal seat 316 is arranged between the water pump assembly 400 and the inspection port 116, which means that the terminal seat 316 is arranged between the inspection plate 220 and the water pump assembly 400. After the inspection plate 220 is opened, the terminal seat 316 is first exposed at the inspection port 116. When disassembling the water pump assembly 400, while separating the water pump assembly 400 from the housing 100, it is also necessary to separate the electrical connection between the water pump assembly 400 and the electric control assembly 300. Therefore, the terminal seat 316 is arranged between the water pump assembly 400 and the inspection plate 220, which will not affect the disassembly and assembly of the water pump assembly 400.

[0247] In some embodiments, the terminal seat 316 and the electric control box 310 are an integrated structure. The electric control box 310 includes a box body 312 and a box cover 314, the box body 312 has a box opening 315, the box cover 314 is detachably connected to the box body 312, and can open or close the box opening 315, and the circuit board 320 is detachably arranged in the box body 312. The terminal seat 316 and the electric control box 310 are an integrated structure, which means that the terminal seat 316 and the box body 312 are an integrated structure, and the two are a whole, which can reduce the processing steps between the terminal cover 317 and the box body 312, and reduce the manufacturing cost.

[0248] In some embodiments, the electric control assembly 300 further includes a terminal cover 317, which is arranged on the terminal seat 316 to protect the connection terminals on the terminal seat 316, and plays a role of protecting the connection wires, that is, the terminal cover 317 can protect the connection terminals of the water pump assembly 400 and the electric control assembly 300. That is, after the inspection panel 220 is opened, the terminal cover 317 is first exposed at the inspection port 116. After the terminal seat 316 is disassembled, the terminal seat 316 is exposed, so that the connection terminals of the water pump assembly 400 are exposed, and the electrical connection between the water pump assembly 400 and the electric control assembly 300 can be separated, thereby facilitating the disassembly and assembly of the water pump assembly 400.
