Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0050] It should be noted that all the directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indication will also change accordingly.

[0052] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0053] With the development of society, electrical appliances such as air conditioners are gradually widely used. When installing an air conditioner, in order to reduce the occupied space, the air conditioner can be installed in the ceiling, that is, the indoor unit of the air conditioner can be installed in the ceiling. Due to the limited space of the ceiling, the size of the air conditioner cannot be too large. In the related art, the thickness of the air conditioner is relatively thick, resulting in a relatively large size of the entire air conditioner. The air conditioner provided in the embodiments of the present application can improve the above problems. The air conditioner provided in the embodiments of the present application has a compact structure and reduces the volume of the air conditioner.

[0054] The present application will be described below in conjunction with the accompanying drawings and specific embodiments:

[0055] Please refer to Figure 1 , an air conditioner 10 is provided in an embodiment of the present application. The air conditioner 10 provided in the embodiment of the present application has a compact structure, reducing the volume of the air conditioner 10.

[0056] In some embodiments, the air conditioner 10 includes: a housing 100, a main body structure 500, a water pump assembly 400, and an electric control assembly 300. The housing 100 has a receiving cavity 112; the main body structure 500 is disposed in the receiving cavity 112 and communicates with an air outlet 114; the water pump assembly 400 and the electric control assembly 300 are disposed on the same side of the main body structure 500, and the water pump assembly 400, the electric control assembly 300, and the main body structure 500 are arranged side by side.

[0057] The housing 100 is the main body of the entire air conditioner 10, providing an installation foundation for other components of the air conditioner 10. Other components of the air conditioner 10 are installed in the receiving cavity 112 of the housing 100. The housing 100 can protect other components of the air conditioner 10, reducing the risk of external impurities entering the receiving cavity 112 and protecting other internal structures. And placing all other components inside the housing 100 can make the air conditioner 10 form a whole, facilitating the installation and transportation of the air conditioner 10.

[0058] Among them, the main body structure 500 may include structures such as a fan assembly 520, a duct assembly 510, and a heat exchanger 530, capable of realizing the refrigeration and heating functions of the air conditioner 10.

[0059] The water pump assembly 400, the electric control assembly 300, and the main body structure 500 are arranged side by side, which means they are arranged side by side in the width direction X of the housing 100. The space in the width direction X of the housing 100 can be utilized to arrange the electric control assembly 300 and the water pump assembly 400, minimizing the occupation of the space in the thickness direction Y or the height direction Z of the housing 100, enabling the components inside the entire housing 100 to be compactly arranged, thereby reducing the volume of the air conditioner 10.

[0060] Since the water pump assembly 400 and the electric control assembly 300 are located on the same side of the main body structure 500, and both the water pump assembly 400 and the electric control assembly 300 can be exposed outside the inspection opening 116 when the inspection plate 220 is opened to form 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 simultaneously inspected through the same inspection opening 116.

[0061] In some embodiments, the air conditioner 10 further includes a water receiving tray 210. The water receiving tray 210 is disposed in the accommodation cavity 112 and below the main body structure 500, and the electronic control component 300 is mounted on the water receiving tray 210.

[0062] During the operation of the air conditioner 10, there is a certain temperature difference between the interior of the housing 100 and the room. Especially during the refrigeration process, when the air entering the accommodation cavity 112 from the room exchanges heat with the heat exchanger 530, condensed water is generated. To prevent the condensed water from blowing into the room, a water receiving tray 210 is disposed in the accommodation cavity 112 to collect the condensed water and then discharge it.

[0063] The water receiving tray 210 is disposed below the main body structure 500. The water receiving tray 210 needs to be disposed at least below the heat exchanger 530, and can also be disposed below the heat exchanger 530 and the duct assembly 510. Of course, the water receiving tray 210 can also be disposed below the entire accommodation cavity 112, that is, all components in the accommodation cavity 112 are disposed above the water receiving tray 210.

[0064] Since the water receiving tray 210 is disposed below the main body structure 500, mounting the electronic control component 300 on the water receiving tray 210 can eliminate the need to separately provide an installation structure for the electronic control component 300, and utilize the structure of the air conditioner 10 itself to mount the electronic control component 300, thereby achieving the fixed installation of the electronic control component 300.

[0065] Please refer to Figure 2 , in some embodiments, the water receiving tray 210 at least protrudes with a first water retaining member 215, a second water retaining member 216 and a third water retaining member 217. The first water retaining member 215, the second water retaining member 216 and the third water retaining member 217 are sequentially connected to form a limiting groove 214, and the electronic control component 300 is disposed in the limiting groove 214.

[0066] Since the water receiving tray 210 is mainly used to receive condensed water, and there are many electronic components inside the electronic control component 300 that need to be waterproof. When the electronic control component 300 is disposed on the water receiving tray 210, waterproof treatment needs to be carried out to prevent the condensed water in the water receiving tray 210 from invading the electronic control component 300 and affecting the operation of the electronic components in the electronic control component 300.

[0067] The first water baffle 215, the second water baffle 216 and the third water baffle 217 all protrude from the water receiving tray 210, such that there is a certain height between the first water baffle 215, the second water baffle 216, the third water baffle 217 and the bottom surface of the water receiving tray 210, so that the limiting groove 214 formed by the first water baffle 215, the second water baffle 216 and the third water baffle 217 is located above the bottom surface of the water receiving tray 210 rather than inside the water receiving tray 210, and 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, the condensed water hardly enters the limiting groove 214. 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.

[0068] In some embodiments, the housing 100 further has an air outlet 114 and a maintenance port 116 communicating with the accommodation cavity 112. The air outlet 114 and the maintenance port 116 are located on the same side of the housing 100, and the limiting groove 214 communicates with the maintenance port 116.

[0069] The maintenance port 116 and the air outlet 114 are provided on the same side of the housing 100, that is, the maintenance port 116 and the air outlet 114 are provided on the same plane of the housing 100. Then it can be considered that the maintenance port 116 is also provided at the air blowing outlet 22 and within the area of the air blowing outlet 22. The maintenance plate 220 covers the maintenance port 116, so the maintenance plate 220 is also provided within the area of the air blowing outlet 22.

[0070] Among them, the first water baffle 215, the second water baffle 216 and the third water baffle 217 form a limiting groove 214 having a notch 214a. The limiting groove 214 communicates with the maintenance port 116. It can be considered that the notch 214a of the limiting groove 214 communicates with the maintenance port 116. When the maintenance port 116 is opened, the electric control component 300 can be directly withdrawn from the limiting groove 214, and the disassembly and assembly method is simple.

[0071] Wherein, the first water retaining member 215 and the third water retaining member 217 are respectively connected to both 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.

[0072] 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, and has a certain distance between it and the rear wall of the shell 100.

[0073] 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 near 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 electronic control assembly 300 and the water pump assembly 400 are arranged near the inspection port 116. Therefore, it can be considered that in the thickness direction Y of the housing 100, the electronic control assembly 300, the water pump assembly 400, and the air duct assembly 510 are arranged in the same position, and the heat exchanger 530 is arranged behind the electronic control assembly 300, the water pump assembly 400, and the air duct assembly 510. In other words, along the width direction X of the housing 100, the projections of the electronic control assembly 300, the water pump assembly 400, and the air duct assembly 510 on the housing 100 overlap, while the projections of the electronic control assembly 300 and the heat exchanger 530 on the housing 100 are staggered.

[0074] The first side plate assembly 160 may be provided with a first drain port 161 and a second drain port 162. The first drain port 161 is arranged close to the inspection port 116, and the second drain port 162 is arranged away from the inspection port 116. That is, in the thickness direction Y of the housing 100, the first drain port 161 is arranged at the rear side of the second drain port 162, and the first drain port 161 is arranged 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 coincides with the first drain port 161. And the first drain port 161 is communicated with the water receiving tray 210, and the second drain port 162 is communicated with the water pump part 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.

[0075] The second water retaining member 216 is arranged at the rear side of the electric control assembly 300, so that a water guiding channel can be formed between the second water retaining member 216 and the rear wall of the water receiving tray 210. After the heat exchanger 530 generates condensed water, the condensed water will fall onto the water receiving tray 210 under the action of gravity. The water receiving tray 210 is inclined towards the direction of the first side plate assembly 160, so that the condensed water will flow through the water guiding channel towards the first drain port 161 and be discharged out of the housing 100 through the first drain port 161. If it cannot be completely discharged through the first drain port 161, the water pump assembly 400 can be used to forcibly drain the condensed water in the water receiving tray 210.

[0076] That is to say, along the width direction X of the housing 100, the projections of the electric control assembly 300 and the heat exchanger 530 on the housing 100 are staggered. A water guiding 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 through the water guiding channel towards the first drain port 161. The electric control assembly 300 is not arranged on the flow path of the condensed water, which can also reduce the risk of condensed water entering the limiting groove 214 to a certain extent.

[0077] In some embodiments, the heights 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 greater than or equal to 25 mm.

[0078] Among them, the first drain port 161 with automatic drainage function makes the condensed water in the water receiving tray 210 basically not accumulate too much, basically not exceeding 25 mm. Therefore, the heights 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 25 mm. 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 the condensed water on the electric control assembly 300, thereby improving the service life of the electric control assembly 300.

[0079] Among them, since the second water baffle 216 is located at the rear side of the electronic control component 300 and mainly functions to block water, the second water baffle 216 can be set relatively high, even higher than the height of the electronic control component 300 in the height direction Z of the housing 100, so as to prevent condensed water from entering the limiting groove 214.

[0080] In some embodiments, a first water baffle 215 is provided between the water pump component 400 and the electronic control component 300, and the first water baffle 215 has a water separation groove 215a.

[0081] The first water baffle 215 is arranged between the water pump component 400 and the electronic control component 300, and the third water baffle 217 is arranged between the electronic control component 300 and the main body structure 500. During the forced drainage process of the water pump component 400, water will enter the area of the water pump component 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 component 400 and the electronic control component 300 relatively low. The electronic control component 300 generates heat during operation, resulting in a relatively large temperature difference between the electronic control component 300 and the surrounding gas, and thus it is easy to generate condensation. By providing the water separation groove 215a on the first water baffle 215, the distance between the water pump component 400 and the electronic control component 300 can be increased, that is, the distance between the electronic control component 300 and the cold air is increased, thereby reducing the condensation on the outside of the electronic control component 300 and reducing the condensation from entering the electronic control component 300 and affecting the service life of the electronic control component 300.

[0082] In some embodiments, the width of the water separation groove 215a is greater than or equal to 10 mm.

[0083] The width of the water separation groove 215a refers to the width in the width direction X of the housing 100. If the width of the water separation 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 there is a certain distance between the electronic control component 300 and the cold air near the water pump component 400, thereby reducing the condensation on the outside of the electronic control component 300 and reducing the condensation from entering the electronic control component 300 and affecting the service life of the electronic control component 300.

[0084] Specifically, the width of the water separation 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.

[0085] In some embodiments, the air conditioner 10 further includes a thermal insulation layer 230 disposed in the water separation groove 215a. In order to further isolate the area between the electronic control component 300 and the water pump component 400, a thermal insulation layer 230 can be provided in the water separation groove 215a so that the air in the limiting groove 214 can be maintained within a certain temperature range, thereby reducing the occurrence of condensation on the outside of the electronic control component 300 and reducing the entry of condensation into the electronic control component 300, which affects the service life of the electronic control component 300.

[0086] Of course, in some other embodiments, the water separation groove 215a can also be provided on the second water retaining member 216 and / or the third water retaining member 217, and a thermal insulation layer 230 is provided in the water separation groove 215a, or only the water separation groove 215a is provided on the second water retaining member 216 and / or the third water retaining member 217, without providing a thermal insulation layer 230. Specifically, it can be not limited.

[0087] In some embodiments, the electronic control component 300 is disposed between the water pump component 400 and the main body structure 500.

[0088] The electronic control component 300 needs to be electrically connected to both the fan component 520 and the water pump component 400. If the water pump component 400 is disposed between the electronic control component 300 and the main body structure 500, the wiring of the main body structure 500 needs to cross over the water pump component 400, increasing the length of the connecting wire of the main body structure 500. Similarly, if the main body structure 500 is disposed between the water pump component 400 and the electronic control component 300, the wiring between the water pump components 400 needs to cross over the main body structure 500, which also increases the length of the connecting wire of the water pump component 400. Disposing the electronic control component 300 between the main body structure 500 and the water pump component 400, that is, the electronic control component 300 is disposed in the middle of the main body structure 500 and the water pump component 400, enables the length of the connecting wire to be as short as possible, thereby reducing the length of the connecting wire and facilitating the arrangement and fixation of the connecting wire.

[0089] Please refer to Figure 3 , in some embodiments, the electronic control component 300 includes an electronic control box 310, a circuit board 320 (please refer to Figure 9 ), a terminal block 316. The circuit board 320 is disposed in the electronic control box 310. The water pump component 400 is connected to the terminal block 316 through a connecting wire, and the terminal block 316 is disposed between the water pump component 400 and the maintenance port 116.

[0090] The terminal block 316 is provided on the outer side of the electric control box 310 and is mainly connected to the connection terminals of the water pump assembly 400, enabling the water pump assembly 400 to be electrically connected to the electric control assembly 300. The terminal block 316 is provided between the water pump assembly 400 and the inspection port 116, which means that the terminal block 316 is provided between the inspection plate 220 and the water pump assembly 400. After the inspection plate 220 is opened, first, the terminal block 316 is 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, setting the terminal block 316 between the water pump assembly 400 and the inspection plate 220 will not affect the disassembly and assembly of the water pump assembly 400.

[0091] In some embodiments, the terminal block 316 and the electric control box 310 are of an integral 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, and 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 arranged inside the box body 312. The fact that the terminal block 316 and the electric control box 310 are of an integral structure means that the terminal block 316 and the box body 312 are of an integral structure. The two being an integral body can reduce the processing procedures between the terminal cover 317 and the box body 312 and reduce the manufacturing cost.

[0092] In some embodiments, the electric control assembly 300 further includes a terminal cover 317. The terminal cover 317 covers the terminal block 316 and is used to protect the wiring terminals on the terminal block 316, which plays a role in protecting and safeguarding the connecting wires. That is, the terminal cover 317 can protect the connection terminals between the water pump assembly 400 and the electric control assembly 300. That is, after the inspection plate 220 is opened, first, the terminal cover 317 is exposed at the inspection port 116. After the terminal block 316 is disassembled, the terminal block 316 is exposed, making the connection terminals of the water pump assembly 400 exposed, enabling the electrical connection between the water pump assembly 400 and the electric control assembly 300 to be separated, thus facilitating the disassembly and assembly of the water pump assembly 400.

[0093] The above structure illustrates how the electric control assembly 300 and the water pump assembly 400 are arranged inside the housing 100. Below, how the electric control assembly 300 and the water pump assembly 400 are installed and disassembled will be introduced.

[0094] Please refer to Figure 4 and Figure 5, in some embodiments, the air conditioner 10 includes: a housing 100, a main body structure 500, an electronic control component 300, and a maintenance panel 220. The housing 100 has a receiving cavity 112, an air outlet 114 and a maintenance opening 116 communicating with the receiving cavity 112. The air outlet 114 and the maintenance opening 116 are located on the same side of the housing 100; the main body structure 500 is disposed in the receiving cavity 112 and communicates with the air outlet 114; the maintenance panel 220 is installed on the housing 100 and can open or close the maintenance opening 116; the electronic control component 300 is detachably disposed in the receiving cavity 112 and can be exposed through the maintenance opening 116 when the maintenance panel 220 opens the maintenance opening 116.

[0095] Among them, the main body structure 500 may include structures such as a fan assembly 520, a duct assembly 510, and a heat exchanger 530, and can realize the functions of refrigeration and heating of the air conditioner 10. The entire air conditioner 10 is installed in the ceiling 21 (such as Figure 6 and Figure 7 shown), and an air outlet 22 communicating with the air outlet 114 and a return air outlet communicating with the air inlet will be provided on the ceiling 21. The indoor air passes through the return air outlet and then enters the receiving cavity 112 through the air inlet. After heat exchange through the heat exchanger 530, it will be blown into the room through the air outlet 114 and the air outlet 22.

[0096] In order to enable the air after heat exchange to be blown into the room as soon as possible, the air outlet 114 and the air outlet 22 are basically only separated by a very small distance, so that the air outlet 114 and the air outlet 22 are basically overlapped, and it can be considered that the air outlet 114 is provided at the air outlet 22, that is, in the area of the air outlet 22.

[0097] In some embodiments, the maintenance opening 116 and the air outlet 114 are provided on the same side of the housing 100, that is, the maintenance opening 116 and the air outlet 114 are provided on the same plane of the housing 100, then it can be considered that the maintenance opening 116 is also provided at the air outlet 22, in the area of the air outlet 22. The maintenance panel 220 covers the maintenance opening 116, so the maintenance panel 220 is also provided in the area of the air outlet 22.

[0098] Among them, when the maintenance panel 220 opens the maintenance opening 116, the fact that the electronic control component 300 can be exposed through the maintenance opening 116 means that when the maintenance opening 116 is opened, there is no other structure blocking the electronic control component 300, and the electronic control component 300 can be directly exposed from the maintenance opening 116, and the user can directly remove the electronic control component 300 from the housing 100 through the maintenance opening 116.

[0099] In the case where the electronic control component 300 fails and needs to be repaired, the air outlet grille 23 at the air outlet 22 can be removed first, so that the plane of the housing 100 provided with the inspection opening 116 and the air outlet 114 is exposed. Then, the inspection opening 116 is opened, so that the electronic control component 300 can be exposed through the inspection opening 116 and the air outlet 22. Then, the electronic control component 300 can be directly inspected or replaced. The operation is simple and convenient, and installation structures such as the ceiling 21 do not need to be removed, which can reduce the maintenance cost of the electronic control component 300.

[0100] It should be noted that the air conditioner 10 includes two parts: 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, rather than installing both the indoor unit and the outdoor unit in the ceiling 21. This part belongs to the common knowledge in the field and will not be elaborated here.

[0101] In some embodiments, the inspection plate 220 is detachably connected to the housing 100. Since the air conditioner 10 is installed in the ceiling 21, in order to minimize the occupied space and reduce the area of the box opening 315 of the air outlet 22, basically the width of the air conditioner 10 is slightly smaller than the width of the air outlet 22. The inspection plate 220 is detachably connected to the housing 100. When inspecting the electronic control component 300, the inspection plate 220 can be directly detached and connected, so that the inspection plate 220 does not occupy the space of the air outlet 22, and the inspection opening 116 can be fully opened, which is convenient for inspecting the electronic control component 300.

[0102] Among them, as for the specific detachable connection method between the inspection plate 220 and the housing 100, connection holes can be respectively provided on the housing 100 and the inspection plate 220, and they can be detachably connected by means of screws or bolt nuts.

[0103] In addition, in addition to being detachably connected to the housing 100, the inspection plate 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 component 510, and can be detachably connected to the water pump component 400. The specific detachable method can refer to the detachable connection method between the inspection plate 220 and the housing 100, which will not be elaborated here.

[0104] Of course, in addition to this, in some other embodiments, the inspection plate 220 can also be rotatably connected or slidably connected to the housing 100, as long as the function of opening and closing the inspection opening 116 can be realized.

[0105] Referring to FIG. 8, in some embodiments, the air conditioner 10 further includes a water receiving tray 210. The water receiving tray 210 is disposed in the accommodation cavity 112 and below the main body structure 500. The electronic control component 300 is mounted on the water receiving tray 210 and is detachably connected to the water receiving tray 210.

[0106] During the operation of the air conditioner 10, there is a certain temperature difference between the interior of the housing 100 and the room. Especially during the refrigeration process, when the air entering the accommodation cavity 112 from the room exchanges heat with the heat exchanger 530, condensed water will be generated. To prevent the condensed water from blowing into the room, a water receiving tray 210 is provided in the accommodation cavity 112 to collect the condensed water and then discharge it.

[0107] The water receiving tray 210 is disposed below the main body structure 500. The water receiving tray 210 needs to be disposed at least below the heat exchanger 530, and may also be disposed below the heat exchanger 530 and the duct assembly 510. Of course, the water receiving tray 210 may also be disposed below the entire accommodation cavity 112, that is, all components in the accommodation cavity 112 are disposed above the water receiving tray 210.

[0108] Since the water receiving tray 210 is disposed below the main body structure 500, mounting the electronic control component 300 on the water receiving tray 210 can eliminate the need to separately provide an installation structure for the electronic control component 300, and utilize the structure of the air conditioner 10 itself to mount the electronic control component 300, achieving fixed installation of the electronic control component 300.

[0109] Referring to FIG. 9, in some embodiments, the electronic control component 300 includes an electronic control box 310 and a circuit board 320. The electronic control box 310 has an installation cavity 330. The circuit board 320 is mounted in the installation cavity 330 and is detachably connected to the electronic control box 310. The electronic control box 310 is detachably connected to the water receiving tray 210.

[0110] Among them, the circuit board 320 is disposed in the installation cavity 330 and is detachably connected to the electronic control box 310. The electronic control box 310 is also detachably connected to the water receiving tray 210. That is, during maintenance, the entire electronic control box 310 and the circuit board 320 can be removed and then repaired or replaced. It is also possible to only remove the circuit board 320 for repair or replacement. It can be selected whether to disassemble the whole or only the circuit board 320 according to the specific replacement structure, and the operation is flexible and convenient.

[0111] 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.

[0112] Among them, the box body 312 and the box cover 314 form the electric control box 310, and the box body 312 and the box cover 314 form the 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 performing maintenance, the entire electric control box 310 and the circuit board 320 can be removed and then repaired or replaced. It is also possible to only remove the circuit board 320 for maintenance or replacement. Whether to disassemble the whole or only the circuit board 320 can be selected according to the specific replacement structure, and the operation is flexible and convenient.

[0113] In some embodiments, the electric control component 300 further includes a terminal cover 317. The terminal cover 317 is connected to the box cover 314 and is mainly used to cover the outside of the connection wire or the terminal, playing a protective role for the connection wire.

[0114] In some embodiments, a fixing groove 318 is provided in the box body 312. The fixing groove 318 extends in the thickness direction Y of the housing 100 away from the inspection port 116, and the circuit board 320 is installed in the fixing groove 318.

[0115] Among them, the housing 100 is generally a cuboid. The housing 100 has three directions: the width direction X, the thickness direction Y, and the height direction Z. The height direction Z refers to the vertical direction of the housing 100 in the installation and use state. The width direction X indicates the direction with the longest length of the housing 100, and the thickness direction Y is the direction perpendicular to both the width direction X and the height direction Z, and is also the direction away from the air outlet 114. For the convenience of description, the positions at both ends of the width direction X of the housing 100 are defined as left and right, the positions at both ends of the height direction Z are defined as up and down, and the positions at both ends of the thickness direction Y are defined as front and back.

[0116] The fixing groove 318 extends in the thickness direction Y of the housing 100 away from the inspection port 116, which means that the extending direction of the fixing groove 318 is consistent with the thickness direction Y of the housing 100, that is, the fixing groove 318 extends in the direction away from the air outlet 114. The extending direction of the fixing groove 318 is substantially the same as the extending 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 disassembled, after opening the box cover 314, drag the circuit board 320 so that the circuit board 320 can slide out of the fixing groove 318 to the outside of the box body 312, and then be disassembled from the electric control box 310.

[0117] In some embodiments, along the thickness direction Y of the housing 100, the projections of the box opening 315 and the inspection port 116 on the inspection board 220 coincide.

[0118] If the projections of the box opening 315 and the inspection opening 116 on the inspection plate 220 at least partially overlap, it means that when the inspection opening 116 is opened on the inspection plate 220, the box opening 315 coincides 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 withdrawn from the electric control box 310, and only the circuit board 320 needs to be disassembled, without disassembling the entire electric control component 300, and the operation is simple and convenient. The maintenance personnel can choose to disassemble the entire electric control component 300 or only the circuit board 320 according to the situation of the electric control component 300. The maintenance method is flexible and controllable, which can increase the operability of maintenance.

[0119] 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 cover the outside of the wiring board 312c. 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 facilitates the assembly and maintenance of the entire electric control component 300.

[0120] The above specifically illustrates how the circuit board 320 is installed and detachable in the electric control box 310. Next, how the electric control box 310 is detachably connected to the water receiving tray 210 will be introduced.

[0121] Please refer to FIG. 10. 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. The first fixing portion 340 and the second fixing portion 212 are detachably connected. Among them, at least one of the first fixing portion 340 and the second fixing portion 212 can be exposed outside the inspection opening 116 when the inspection plate 220 opens the inspection opening 116.

[0122] At least one of the first fixing portion 340 and the second fixing portion 212 can be exposed outside the inspection opening 116 when the inspection plate 220 opens the inspection opening 116. It can be that only the first fixing portion 340 is exposed outside the inspection opening 116 when the inspection plate 220 opens the inspection opening 116, or only the second fixing portion 212 is exposed outside the inspection opening 116 when the inspection plate 220 opens the inspection opening 116, or both the first fixing portion 340 and the second fixing portion 212 are exposed outside the inspection opening 116 when the inspection plate 220 opens the inspection opening 116.

[0123] The first fixing part 340 and the second fixing part 212 are detachably connected, and at least one of them can be exposed outside the inspection port 116 when the inspection plate 220 is opened. When the inspection plate 220 opens the inspection port 116, operations can be directly performed on the first fixing part 340 and the second fixing part 212 to separate the electronic control component 300 from the water receiving tray 210, facilitating the disassembly of the electronic control component 300.

[0124] 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 overlap on the second fixing part 212. Threaded holes can be provided on both the first fixing part 340 and the second fixing hole, and the first fixing part 340 and the second fixing part 212 are detachably connected by screws.

[0125] It is easy to understand that when the inspection plate 220 opens the inspection port 116, the first fixing part 340 can be exposed outside the inspection port 116, then the screws fixing the first fixing part 340 and the second fixing part 212 can also be exposed outside the inspection port 116. During disassembly and assembly, first remove the inspection plate 220 to expose the whole electronic control component 300, and then turn the screws to separate the first fixing part 340 from the second fixing part 212, separating the electronic control box 310 from the water receiving tray 210, so that the electronic control component 300 can be disassembled.

[0126] Please refer to FIG. 11. In some embodiments, the water receiving tray 210 has a limiting groove 214, and the electronic control component 300 is installed in the limiting groove 214. Along the thickness direction Y of the housing 100, the notch 214a of the limiting groove 214 and the inspection port 116 at least partially overlap in the projection on the inspection plate 220.

[0127] The electronic control component 300 is installed in the limiting groove 214, and the limiting groove 214 can play a role in fixing and limiting the electronic control component 300. The notch 214a of the limiting groove 214 and the inspection port 116 at least partially overlap in the projection on the inspection plate 220, which means that when the inspection plate 220 opens the inspection port 116, the notch 214a of the limiting groove 214 coincides with the inspection port 116, that is, the notch 214a of the limiting groove 214 is communicated with the inspection port 116. The electronic control component 300 can be directly pulled out from the limiting groove 214, and the disassembly and assembly method is simple.

[0128] Specifically, the second fixing part 212 can be arranged at the notch 214a of the limiting groove 214. When the electric control component 300 needs to be disassembled, the maintenance plate 220 can be opened first (the maintenance plate 220 is disassembled from the housing 100), and then the screw connecting the first fixing part 340 and the second fixing part 212 is rotated to separate the electric control box 310 from the water receiving tray 210, and then the electric control box 310 is pulled out along the limiting groove 214 until the whole electric control box 310 is separated from the maintenance port 116 to the outside of the accommodating cavity 112.

[0129] The installation process is 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 with the second fixing part 212, and then fix the first fixing part 340 and the second fixing part 212 with screws.

[0130] 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 oppositely, the second water retaining member 216 connects the first water retaining member 215 and the third water retaining member 217, and 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 notch 214a.

[0131] The electric control box 310 is generally a cuboid, 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 generally a rectangular cavity of a notch 130, and this notch 130 is the notch 214a of the limiting groove 214. The limiting groove 214 can play a certain role in limiting and guiding, and can facilitate the installation and fixation of the electric control box 310.

[0132] Since the electric control box 310 is generally a cuboid, and the limiting groove 214 surrounded 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 cuboid cavity, the shape of the limiting groove 214 is adapted to the shape of the electric control box 310 and can be slightly larger than the size of the electric control box 310. When the electric control box 310 is fixedly installed, the occupied space of the electric control component 300 can be reduced, and the components in the accommodating cavity 112 can be arranged compactly, and the volume of the air conditioner <10> can be reduced as much as possible.

[0133] In summary, in some embodiments of the present application, when the electronic control component 300 fails and needs to be repaired, the air outlet grille 23 at the air outlet 22 can be removed first, so that the plane of the housing 100 provided with the inspection opening 116 and the air outlet 114 is exposed. Then, the inspection opening 116 is opened, so that the electronic control component 300 can be exposed through the inspection opening 116 and the air outlet 22. Then, the entire electronic control component 300 or only the circuit board 320 can be directly repaired or replaced. The operation is simple and convenient, and there is no need to remove installation structures such as the ceiling 21, which can reduce the maintenance cost of the electronic control component 300.

[0134] Please refer to FIG. 12. In some embodiments, the air conditioner 10 further includes a water pump assembly 400. The water pump assembly 400 is detachably disposed in the accommodation cavity 112 and can be exposed outside the inspection opening 116 when the inspection plate 220 opens the inspection opening 116.

[0135] During the operation of the air conditioner 10, especially during the refrigeration process, due to the large temperature difference between the indoor air and the heat exchanger 530, after entering the accommodation cavity 112, condensed water will be generated near the heat exchanger 530. The condensed water will drip onto the water receiving tray 210 below the heat exchanger 530. Due to the limited size of the air conditioner 10, the depth of the water receiving tray 210 cannot be set too large, and the condensed water in the water receiving tray 210 needs to be discharged in time. The water pump assembly 400 is disposed in the accommodation cavity 112 and is mainly used to drain the condensed water in the water receiving tray 210 to prevent the condensed water in the water receiving tray 210 from overflowing.

[0136] The water pump assembly 400 can be exposed outside the inspection opening 116 when the inspection plate 220 is opened. If the water pump assembly 400 fails and needs to be repaired or replaced, first remove the air outlet grille 23 at the air outlet 22, so that the plane of the housing 100 provided with the inspection opening 116 and the air outlet 114 can be exposed. Then, open the inspection plate 220, so that the water pump assembly 400 can be exposed through the inspection opening 116 and the air outlet 22. The maintenance personnel can reach into the accommodation cavity 112 and detach the water pump assembly 400 from the housing 100. Before detaching the water pump assembly 400, only the air outlet grille 23 at the air outlet 22 and the inspection plate 220 need to be detached, and the operation is simple and convenient. Moreover, the inspection opening 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 the inspection plate 220 can be exposed after the air outlet grille 23 is detached, which is convenient for the operation of the maintenance personnel.

[0137] It should be noted that the maintenance openings 116 corresponding to the water pump assembly 400 and the electronic control assembly 300 can be the same maintenance opening 116 or different maintenance openings 116. Specifically, the water pump assembly 400 and the electronic control assembly 300 can be arranged at the same position in the accommodation cavity 112, and the maintenance opening 116 can be set to be relatively large so as to cover both the water pump assembly 400 and the electronic control assembly 300 at the same time. Or the water pump assembly 400 and the electronic control assembly 300 can be arranged at different positions in the accommodation cavity 112, and two maintenance openings 116 and two maintenance plates 220 are respectively provided. One maintenance opening 116 is arranged corresponding to the electronic control assembly 300, and the other maintenance opening 116 is arranged corresponding to the water pump assembly 400.

[0138] Please refer to FIG. 13. In some embodiments, one side of the housing 100 has a notch 130 communicating with the maintenance opening 116. The water pump assembly 400 includes a bracket 410 and a water pump part 420 installed on the bracket 410. The bracket 410 is detachably installed in the notch 130.

[0139] Among them, the bracket 410 can be a plate-like structure. The bracket 410 is detachably installed in the notch 130, that is, the bracket 410 can be filled in the notch 130, so that the bracket 410 can be used as a part of the housing 100. While fixing the water pump part 420, the bracket 410 can be embedded into the notch 130, which can reduce the occupied space of the water pump assembly 400 in the width direction X of the housing 100, make the structures of the components in the housing 100 compact, and reduce the occupied space of the entire air conditioner 10.

[0140] The notch 130 communicates with the maintenance opening 116, which means that at least one side of the notch 130 is in an open state and has an opening on at least one side, and this opening communicates with the maintenance opening 116, so that the bracket 410 can be embedded into or detached from the notch 130. During installation, a part of the bracket 410 can be first placed into the notch 130, and then the entire water pump assembly 400 is pushed inward, so that the water pump assembly 400 can slide inward and thus be embedded into the notch 130. During disassembly, the process is opposite. The entire water pump assembly 400 is pulled outward, so that the bracket 410 slides out of the notch 130 and finally slides out of the maintenance opening 116 to the outside of the accommodation cavity 112.

[0141] Among them, the bracket 410 is generally rectangular. In order to be adapted to the bracket 410, the shape of the notch 130 is also rectangular. Since the notch 130 is also connected to the inspection opening 116, the side of the notch 130 close to the inspection opening 116 has an opening. In addition, the notch 130 has three sides, namely the first side 131 located below, the second side 132 arranged vertically, the second side 132 is arranged opposite to the inspection opening 116, and the third side located above. Next, how the bracket 410 is assembled and fixed in the notch 130 will be specifically introduced, that is, how it is assembled and fixed with the first side 131, the second side 132, etc.

[0142] Please refer to FIG. 14. In some embodiments, the first side 131 is provided below the notch 130. The first side 131 is provided with a first stop portion 131a protruding towards the accommodation cavity 112 and a second stop portion 131b protruding towards the notch 130. The second stop portion 131b can be in contact with the bracket 410. The first stop portion 131a is arranged below the bracket 410. At least one of the first stop portion 131a and the second stop portion 131b is detachably connected to the bracket 410.

[0143] In the use state of the air conditioner 10, the first stop portion 131a protrudes towards the inside of the accommodation cavity 112, then it can be considered that the first stop portion 131a is arranged substantially horizontally. The second stop portion 131b protrudes towards the inside of the notch 130, and the second stop portion 131b is arranged on the first side 131 below the notch 130, which indicates that the second stop portion 131b is arranged substantially vertically.

[0144] Please refer to FIG. 15. Among them, the bracket 410 may include a plate body 412, a first flanging 413 and a second flanging 415. The plate body 412 is installed in the notch 130. The first flanging 413 is connected to the plate body 412 and is arranged at an angle with the plate body 412. The first flanging 413 is arranged above the first stop portion 131a and is in contact with the first stop portion 131a. That is, the first flanging 413 is lapped on the first stop portion 131a.

[0145] The second flanging 415 is connected to the first flanging 413 and is arranged at an angle with the first flanging 413. It can be considered that in the width direction X of the housing 100, the second flanging 415 and the plate body 412 are respectively located on both sides of the first flanging 413, so that the shape formed by the plate body 412, the first flanging 413 and the second flanging 415 is substantially Z-shaped. In the use state of the air conditioner 10, the second flanging 415 is located below the first flanging 413. A card slot 131c is provided on the first stop portion 131a, and the second flanging 415 is inserted into the card slot 131c.

[0146] Among them, the first flanging 413 and the first stop portion 131a may only overlap, or may be detachably connected while overlapping, and no specific limitation is required.

[0147] Referring to FIG. 16, in some embodiments, the notch 130 has a second side 132 disposed opposite to the inspection opening 116. The second side plate has a third stop portion 132a protruding toward the accommodation cavity 112, and the third stop portion 132a is detachably connected to the bracket 410.

[0148] The second side 132 and the inspection opening 116 are spaced apart in the thickness direction Y of the housing 100. The inspection opening 116 is located in front of the second side 132. The bracket 410 further includes a third flanging 416, and the third flanging 416 is disposed in front of the third stop portion 132a and overlaps the third stop portion 132a.

[0149] Among them, the third stop portion 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 located above the notch 130, so that the third flanging 416 slides downward along the guide groove 132b until the first flanging 413 overlaps with the first stop portion 131a, and the second flanging 415 is inserted into the card slot 131c, which means that the water pump assembly 400 is installed in place in the thickness direction Y of the housing 100. Then, the third flanging 416 and the third stop portion 132a are fixedly connected. As for the detachable fixing method between the third flanging 416 and the third stop portion 132a, it can be connected by bolts, screws, etc.

[0150] In some embodiments, the third stop portion 132a includes a first stop segment 132c and a second stop segment 132d connected at an angle. One side of the first stop segment 132c away from the second stop segment 132d is connected to the housing 100, that is, the second stop segment 132d and the notch 130 are respectively located on the left and right sides of the first stop segment 132c. The first stop segment 132c, the second stop segment 132d and the housing 100 form the guide groove 132b. During the installation of the water pump assembly 400, the entire water pump assembly 400 is first located above the first stop portion 131a, so that the third flanging 416 can be located in the guide groove 132b, and then the entire water pump assembly 400 is placed downward, so that the third flanging 416 can slide in the guide groove 132b until the second flanging 415 is inserted into the card slot 131c, and the second stop portion 131b is located on the left side of the plate body 412. Then, the third flanging 416 and the third stop portion 132a are fixedly connected from the front of the water pump assembly 400, that is, the water pump assembly 400 is fixed on the housing 100.

[0151] That is to say, the guiding groove 132b and the second stop portion 131b can limit both sides of the water pump assembly 400 in the width direction X, while the first stop segment 132c can limit in the thickness direction Y, and the first stop portion 131a can limit the water pump assembly 400 in the height direction Z, so as to fix the water pump assembly 400 in the housing 100.

[0152] Similarly, if it is necessary to repair the water pump assembly 400, the third stop portion 132a can be separated from the third flanging 416 first, and then the whole water pump assembly 400 is pulled upward, so that the second flanging 415 is disengaged from the card slot 131c, and it can be removed from the maintenance port 116 to the outside of the accommodation cavity 112. That is to say, when disassembling the water pump assembly 400, only the fixing structure between the third flanging 416 and the third stop portion 132a needs to be disassembled, and the operation is simple and convenient.

[0153] The above is the detachable connection method between the water pump assembly 400 and the housing 100, as well as how to install and fix the water pump assembly 400. Next, the specific installation position of the water pump assembly 400 in the housing 100 will be introduced.

[0154] Please refer to Figure 17 , in some embodiments, the housing 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 an accommodation cavity 112, and the bracket 410 is detachably connected to the first side plate assembly 160.

[0155] The top plate 140 refers to the plate at the top of the air conditioner 10 in the use state, and the bottom plate 150 refers to the plate at the bottom of the air conditioner 10 in the use state. That is, the top plate 140 is above the bottom plate 150, 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 both ends of the top plate 140 and the bottom plate 150.

[0156] Among them, the top plate 140 and the bottom plate 150 are substantially the same in shape and size. The top plate 140 and the bottom plate 150 are substantially strip-shaped plates. The first side plate assembly 160 and the second side plate assembly 170 are respectively arranged at both ends in the length direction of the top plate 140 and the bottom plate 150 (referring to the width direction X of the housing 100). The bracket 410 is detachably connected to the first side plate assembly 160, indicating that the water pump assembly 400 is installed at one end of the housing 100. The water receiving tray 210 can be inclined in the direction towards 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 situation of condensed water overflow as much as possible.

[0157] Since the water pump assembly 400 is mainly used to drain the condensed water on the water receiving tray 210, and the bracket 410 is detachably connected to the first side plate assembly 160, the entire water pump assembly 400 is actually suspended and fixed on the side wall of the housing 100. That is, there is a certain distance between the water pump assembly 400 and the bottom surface of the water receiving tray 210, which can avoid the situation that some components of the water pump assembly 400 are immersed in the condensed water and cause damage as much as possible, and can improve the service life of the water pump assembly 400.

[0158] When the water pump assembly 400 needs to be disassembled, the bracket 410 can be separated from the first side plate assembly 160, so as to disassemble the entire water pump assembly 400 from the housing 100.

[0159] In some embodiments, at least one of the first side plate assembly 160 and the bracket 410 is provided with a first connecting portion 163, and the inspection plate 220 is provided with a second connecting portion 221. The first connecting portion 163 and the second connecting portion 221 are detachably connected.

[0160] Since the notch 130 is communicated with the inspection opening 116, it indicates that one surface of the notch 130 faces the inspection opening 116. That is, one side of the bracket 410 can be located in the area of the inspection opening 116. That is, the inspection plate 220 can be detachably connected only to the first side plate assembly 160, or only to the bracket 410, or can be detachably connected to both the first side plate assembly 160 and the bracket 410 at the same time.

[0161] As for the detachable connection manner between the first connecting portion 163 and the second connecting portion 221, through holes can be respectively provided on the first connecting portion 163 and the second connecting portion 221, and they can be detachably connected by screws or bolts.

[0162] In some embodiments, the air conditioner 10 further includes a water receiving tray 210. The water receiving tray 210 is disposed below the main body structure 500, and the water pump member 420 is disposed above the water receiving tray 210. The water pump member 420 is disposed below the water receiving tray 210, so that the water inlet of the water pump member 420 can extend into the water receiving tray 210 and contact the condensed water in the water receiving tray 210, thereby discharging the condensed water to the outside of the housing 100.

[0163] Please refer to Figure 18 , specifically, the water pump member 420 may include a pump body 421, a fixing clamp 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, and the drain pipe 423 is connected to the pump body 421. The water in the water receiving tray 210 is discharged to the outside of the housing 100 through the water inlet of the pump body 421.

[0164] 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 member 420 to discharge the condensed water in the water receiving tray 210, preventing the condensed water in the water receiving tray 210 from overflowing.

[0165] Please refer to FIGS. 19, Figure 20 and Figure 21 , in some embodiments, the air conditioner 10 includes: a housing 100, an air duct assembly 510 and a fan assembly 520. The housing 100 has a receiving cavity 112 and an air outlet 114 communicating with the receiving cavity 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 disposed in the receiving cavity 112, and the fan assembly 520 is disposed 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 housing 100; wherein, in the first air duct 513 and the second air duct 514, the first air duct 513 is disposed close to the air outlet 114, and the first air duct 513 is detachably connected to the housing 100 and / or the second air duct 514.

[0166] 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 methods. In the first case, the fan assembly 520 is only detachably connected to one of the first air duct 513, the second air duct 514 and the housing 100. For example: the fan assembly 520 may be only detachably connected to the first air duct 513, or the fan assembly 520 may be only detachably connected to the second air duct 514, or the fan assembly 520 may be only detachably connected to the housing 100.

[0167] 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 simultaneously. For example: the fan assembly 520 can be detachably connected to the first air duct 513 and the second air duct 514 simultaneously, or the fan assembly 520 can be detachably connected to the first air duct 513 and the housing 100 simultaneously, or the fan assembly 520 can be detachably connected to the second air duct 514 and the housing 100 simultaneously.

[0168] 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 simultaneously. The specific detachable connection manner of the fan assembly 520 may not be specifically limited.

[0169] The air outlet duct is formed by the first air duct 513 and the second air duct 514. The fan assembly 520 is disposed in the air outlet passage 512. The fan assembly 520 can be disposed inside the first air duct 513, or the fan assembly 520 can be disposed inside the second air duct 514, or the fan assembly 520 can be disposed inside the first air duct 513 and the second air duct 514 simultaneously.

[0170] The first air duct 513 is detachably connected to the housing 100 and / or the second air duct 514. The first air duct 513 can be only connected to the housing 100, or the first air duct 513 can be only detachably connected to the second air duct 514, or the first air duct 513 can be detachably connected to the second air duct 514 and the housing 100 simultaneously.

[0171] The first air duct 513 is disposed near the air outlet 114 and is detachably connected to the housing 100 and / or the second air duct 514. When the fan assembly 520 fails and needs to be repaired, the first air duct 513 can be first detached from the air outlet 114, and then the fan assembly 520 can be detached from the air outlet passage 512, so that the fan assembly 520 can be detached from the air outlet 114, facilitating the repair and cleaning of the fan assembly 520.

[0172] Specifically, since the entire air conditioner 10 is disposed in the ceiling 21, during disassembly, the air outlet grille 23 at the air outlet 22 can be first detached, 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. Then, the first air duct 513 is separated from the second air duct 514 or / and the housing 100, and the first air duct 513 is detached from the air outlet 114, so that the fan assembly 520 can be exposed from the air outlet 114, facilitating the disassembly, installation and repair of the fan assembly 520.

[0173] Of course, in the case where only the first air duct 513 fails and needs to be repaired or replaced, the first air duct 513 can be removed from the housing 100 alone, so that the first air duct 513 can be repaired and cleaned.

[0174] Among them, the first air duct 513 and the second air duct 514 are arranged in sequence in the thickness direction Y of the housing 100. 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 on the front side of the second air duct 514, and the second air duct 514 is arranged on the rear side 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.

[0175] It should be noted that in order to be able to remove the first air duct 513 from the ceiling 21, the dimension of the first air duct 513 in the height direction Z of the housing 100 needs to be smaller than the dimension of the air outlet 22 in the height direction Z of the housing 100, and the dimension of the first air duct 513 in the width direction X of the housing 100 needs to be smaller than the dimension of the air outlet 22 in the width direction X of the housing 100, so as to facilitate the disassembly and assembly of the first air duct 513.

[0176] Specifically, the maximum dimension of the first air duct 513 in the height direction Z of the housing 100 can be less than or equal to 150 mm, so as to ensure that the first air duct 513 can be removed from the air outlet 22.

[0177] In some embodiments, the first air duct 513 passes through the air outlet 114. A part of the first air duct 513 is arranged inside the accommodation cavity 112, and a part of the first air duct 513 is arranged outside the accommodation cavity 112. A part of the first air duct 513 is located inside the accommodation cavity 112, and a part of the first air duct 513 is located outside the accommodation cavity 112. That is, a part of the first air duct 513 is outside the entire housing 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 housing 100, and then remove the first air duct 513 from the ceiling 21. The operation is simple and convenient.
