The detailed description in the detailed implementation modes should be understood as an explanatory illustration of the purpose of this application and should not be regarded as an improper limitation to this application.

[0037] The following further describes this application in detail with reference to the accompanying drawings and specific embodiments. The descriptions such as "first" and "second" in the embodiments of this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0038] An air conditioning device provided by an embodiment of this application, please refer to Figures 1 to 8 , the air conditioning device 100 includes a housing 1 and an evaporator assembly 2. The housing 1 includes pre-installed plate members. The pre-installed plate members include a top surrounding plate 11 and a top cover 12. The top cover 12 is disposed on the top surface of the top surrounding plate 11. The evaporator assembly 2 is disposed on the bottom side of the top cover 12.

[0039] The air conditioning device 100 provided by the embodiment of the present application forms a pre-assembled plate member by arranging the top cover 12 on the top surface of the top perimeter plate 11, and then arranging the evaporator assembly 2 on the bottom side of the top cover 12. On the one hand, setting it as a pre-assembled plate member can ensure the relative position between the top cover 12 and the top perimeter plate 11, so that when installing the evaporator assembly 2 subsequently, the exact position of the evaporator assembly 2 and the top perimeter plate 11 can be guaranteed, reducing installation problems caused by errors and improving the quality and reliability of the air conditioning device 100. On the other hand, pre-assembling the top perimeter plate 11 and the top cover 12 can avoid first installing the top cover 12 on the evaporator assembly 2 and then flipping it 180° and installing it on the top perimeter plate 11. In this way, the operation time and labor intensity can be reduced, and the installation efficiency is high.

[0040] It should be noted that the top cover 12 is a part of the evaporator assembly 2, which can not only play a role in supporting and protecting the evaporator assembly 2, but also play a role in heat preservation or heat insulation.

[0041] Exemplarily, in one embodiment, the air conditioning device 100 can be an air duct machine, such as a thin air duct machine, that is, an air duct machine with a relatively thin thickness.

[0042] In one embodiment, please refer to Figure 2 , the air conditioning device 100 includes a first fastener A, and the first fastener A is penetrated through the evaporator assembly 2 and the top cover 12 from bottom to top to detachably connect the evaporator assembly 2 and the top cover 12. Exemplarily, the housing 1 can be placed on the operating table with the bottom side of the top cover 12 facing upward, then the evaporator assembly 2 is placed on the bottom side of the top cover 12, and finally the first fastener A passes through the evaporator assembly 2 and the top cover 12. In this way, compared with the horizontal installation method inside the housing 1, the bottom-to-top installation can greatly improve the installation efficiency.

[0043] It should be noted that the top refers to the direction facing the ceiling, and the bottom is opposite to the top. The top-bottom direction, the front-back direction, and the left-right direction are perpendicular to each other and jointly form a three-dimensional vertical coordinate system.

[0044] In one embodiment, please refer to Figure 2 , the air conditioning device 100 includes a fixing member B, and the fixing member B is penetrated through the top cover 12 and the top perimeter plate 11 from bottom to top to detachably connect the top cover 12 and the top perimeter plate 11. In this way, through the detachable method of the fixing member B from bottom to top, not only is the installation efficiency high, but it is also convenient for disassembly and replacement.

[0045] Exemplarily, the number of the fixing members B is not limited. For example, it can be 4. Two fixing members B form a group, and the two groups of fixing members B are arranged at intervals in the left-right direction. The two fixing members B in each group are arranged at intervals in the front-back direction, which can greatly improve the connection strength between the top cover 12 and the top perimeter plate 11 and provide stable support for parts such as the evaporator assembly 2.

[0046] In one embodiment, please refer to Figure 2 , the fixing member B is a screw, and the top cover 12 is provided with a blind rivet nut C opening towards the bottom side. The fixing member B is in threaded cooperation with the blind rivet nut C. On the one hand, the blind rivet nut C can be directly single-sided riveted, that is, the screw can be driven from the bottom to the top into the blind rivet nut C to connect the top cover 12 and the top perimeter plate 11, with high installation efficiency; on the other hand, the connection method of the blind rivet nut C can reduce the damage to the working surface and improve the service life of the top perimeter plate 11 and the top cover 12; on the other hand, the connection of the blind rivet nut C and the screw can avoid the situation where the screw protrudes on the top surface of the top perimeter plate 11, facilitating the subsequent installation of the top perimeter plate 11.

[0047] In one embodiment, please refer to Figures 2 to 5 , the evaporator assembly 2 includes an evaporator 21 and two support plates 22. The two support plates 22 are respectively arranged at both ends of the evaporator 21 along the left-right direction. The support plate 22 includes a connecting portion 222 and a mounting portion 221. The connecting portion 222 is connected to the evaporator 21, and the mounting portion 221 is connected to the side of the connecting portion 222 away from the evaporator 21 along the front-back direction. A flanging 221a is formed at the top of the mounting portion 221. The first fastener A is inserted from the bottom to the top through the flanging 221a and the top cover 12, wherein the left-right direction, the top-bottom direction and the front-back direction are perpendicular to each other.

[0048] Exemplarily, the two support plates 22 are respectively a left support plate 22a and a right support plate 22b. Each support plate 22 includes a connecting portion 222 and a mounting portion 221. The connecting portion 222 of the left support plate 22a can be connected to the left end face of the evaporator 21, and the connecting portion 222 of the right support plate 22b can be connected to the right end face of the evaporator 21. For example, it can be fixed to the evaporator 21 by screws or bolts passing through the connecting portion 222. The mounting portion 221 is connected to the side of the connecting portion 222 away from the evaporator 21 along the front-back direction, so that the evaporator assembly 2 is generally in a hoop shape, which is beneficial to concentrating the air duct and facilitating the heat exchange between the air supply and the evaporator 21. A flanging 221a is formed at the top of the mounting portion 221. In this way, the first fastener A can be inserted from the bottom to the top through the flanging 221a and the top cover 12 to connect the mounting portion 221 and the top cover 12, with high installation efficiency. In some embodiments, each flanging 221a can be connected to the top cover 12 by two first fasteners A, so that the connection strength between the evaporator assembly 2 and the top cover 12 can be further increased, with high stability.

[0049] Exemplarily, in one embodiment, please refer to Figure 2 and Figure 3, the connecting part 222 includes a first connecting part 2221 and a second connecting part 2222. The first connecting part 2221 and the second connecting part 2222 are connected to both sides of the evaporator 21 in the front-rear direction. The first connecting part 2221 is connected to the mounting part 221. A flanging 221a is also formed at the top of the second connecting part 2222. The first fastener A is inserted through the flanging 221a and the top cover 12 from bottom to top to further increase the connection strength between the evaporator assembly 2 and the top cover 12, and the stability is good.

[0050] Exemplarily, in one embodiment, the shape of the evaporator 21 is not limited. For example, it can be in the shape of a cuboid.

[0051] Exemplarily, in one embodiment, the evaporator 21 includes heat exchange tubes and fins. The heat exchange tubes are in a spiral shape, and the fins are arranged on the heat exchange tubes to increase the contact area between the air supply and the evaporator 21 and improve the heat exchange efficiency.

[0052] In one embodiment, please refer to Figure 5 , the air conditioning device 100 includes a fourth fastener D and an electric control box 3. Mounting ears 31a are formed on both sides of the bottom plate 31 of the electric control box 3 in the left-right direction. The two mounting ears 31a are respectively located on the bottom sides of the two mounting parts 221. The fourth fastener D is inserted through the mounting ears 31a and the mounting parts 221 from bottom to top.

[0053] Exemplarily, please refer to Figure 5 and Figure 8 , the electric control box 3 includes a bottom plate 31, a surrounding plate 32, electric control components 33 and a box cover 34. The surrounding plate 32 forms a mounting cavity 32a penetrating through the top and bottom sides. The bottom plate 31 is covered on the bottom side of the surrounding plate 32, and the box cover 34 is covered on the top side of the surrounding plate 32 to enclose the mounting cavity 32a. The electric control components 33 are arranged in the mounting cavity 32a. By forming the mounting cavity 32a, the electric control components 33 can be protected to a certain extent and their service life can be improved. Mounting ears 31a are formed on both sides of the bottom plate 31 in the left-right direction. Flanges 221b are formed at the bottoms of the two mounting parts 221. The two mounting ears 31a are respectively lapped on the bottom surfaces of the two flanges 221b. In this way, the fourth fastener D can be inserted through the mounting ears 31a and the flanges 221b from bottom to top to detachably connect the electric control box 3 to the evaporator assembly 2, and the installation efficiency is high.

[0054] In one embodiment, please refer to Figures 2 to 6, the evaporator assembly 2 includes an input / output pipe 23 which is communicated with the heat exchange pipes of the evaporator 21. The air conditioning device 100 includes a water discharge plate 4 and a water receiving tray 5. The water receiving tray 5 covers the bottom side of the evaporator 21. A part of the water discharge plate 4 is recessed towards the bottom side to form a drainage groove 4a. The drainage groove 4a penetrates through the water discharge plate 4 and forms a drainage opening on the side close to the evaporator 21 along the front-rear direction. The drainage groove 4a is located at the bottom side of the input / output pipe 23, and the drainage opening is connected to the water receiving tray 5.

[0055] Exemplarily, a water storage tank 5a with an open top is formed in the water receiving tray 5. The two tank walls of the water storage tank 5a along the front-rear direction can be respectively penetrated by bolts or screws through the first connecting part 2221 and the second connecting part 2222 to arrange the bottom side of the evaporator 21 in the water storage tank 5a. In this way, the condensed water generated during the heat exchange process of the evaporator 21 can drip under the action of gravity into the water storage tank 5a located below it for collection, avoiding the situation that the condensed water drips onto electrical components and other devices causing short circuits and rust, and improving the service life of the air conditioning device 100.

[0056] A part of the water discharge plate 4 is recessed towards the bottom side to form a drainage groove 4a. The drainage groove 4a penetrates through the water discharge plate 4 and forms a drainage hole 4b on the side close to the evaporator 21 along the front-rear direction. The drainage groove 4a is inclined from the side far away from the drainage opening towards the side close to the drainage opening along the front-rear direction. The drainage opening is located above the water storage tank 5a and is communicated with the water storage tank 5a. The drainage groove 4a is located at the bottom side of the input / output pipe 23. The input / output pipe 23 is used to transport the refrigerant in the heat exchange pipes of the evaporator 21. For example, it can transport the heat-exchanged refrigerant out of the evaporator 21 and transport the refrigerant to be heat-exchanged into the heat exchange pipes of the evaporator 21. During the transportation process of the refrigerant, condensed water will also appear in the input / output pipe 23. In this way, by setting the water discharge plate 4, the condensed water can drip onto the drainage groove 4a under the action of gravity, and then enter the water storage tank 5a through the drainage opening along the guidance of the drainage groove 4a for collection, so as to further reduce the probability of condensed water leakage and improve the service life of the air conditioning device 100.

[0057] Exemplarily, in one embodiment, please refer to Figure 5 and Figure 6 , the water receiving tray 5 is formed with a drainage opening 5b communicated with the water storage tank 5a. The air conditioning device 100 includes a drainage pipe which is communicated with the drainage opening 5b and is used to discharge the condensed water in the water storage tank 5a outside the air conditioning device 100.

[0058] Exemplarily, in one embodiment, the number of the drainage openings 5b is multiple, for example, it can be three. In this way, the drainage volume can be increased to quickly discharge the condensed water in the water receiving tray 5, avoiding the generation of peculiar smell and the breeding of bacteria.

[0059] In one embodiment, please refer to Figure 4 andFigure 5 , the air conditioning device 100 includes a third fastener E. The input / output pipe 23 is arranged on one side of the evaporator 21 in the left-right direction. The water discharge plate 4 is located on one side of the support plate 22 close to the input / output pipe 23 in the left-right direction. A flanging 221a is formed at a portion of the water discharge plate 4 close to the support plate 22. The third fastener E is inserted through the flanging 221a and the mounting portion 221 from bottom to top.

[0060] Exemplarily, the input / output pipe 23 can be arranged on the left side of the evaporator 21. The water discharge plate 4 is located on one side of the left support plate 22a close to the input / output pipe 23 in the left-right direction to reduce structural interference. A flanging 221a is formed at a portion of the water discharge plate 4 close to the mounting portion 221 of the left support plate 22a. The flanging 221a can overlap on the folded edge 221b of the mounting portion 221. In this way, the third fastener E can be inserted through the flanging 221a and the folded edge 221b from bottom to top to detachably connect the water discharge plate 4 to the evaporator assembly 2, with high installation efficiency. In some embodiments, the flanging 221a can overlap on the mounting ear 31a. The third fastener E can sequentially pass through the flanging 221a, the mounting ear 31a, and the folded edge 221b from bottom to top to reduce the use of fasteners and save costs.

[0061] In one embodiment, please refer to Figure 3 , the air conditioning device 100 includes a second fastener F and a water baffle 6. The number of the second fasteners F is multiple. The water baffle 6 includes a water blocking portion 61 and two overlapping edges 62. The two overlapping edges 62 are connected to both sides of the water blocking portion 61 in the front-back direction. The water blocking portion 61 is located at the bottom side of the evaporator 21. Some of the second fasteners F are inserted through one of the overlapping edges 62 and the mounting portion 221 from bottom to top, and some of the other second fasteners F are inserted through the other overlapping edge 62 and the connecting portion 222 from bottom to top.

[0062] Exemplarily, a part of the water baffle 6 is recessed downward to form a water retaining portion 61. The water retaining portion 61 penetrates through two side surfaces in the left-right direction. The non-recessed portions of the water baffle 6 in the front-rear direction form two overlapping edges 62. The bottom surface of the mounting portion 221 is higher than the bottom surface of the connecting portion 222. In this way, the water retaining portion 61 can cover the bottom surface of the evaporator 21. One of the two overlapping edges 62 is disposed on the bottom surface of the folded edge 221b of the mounting portion 221, and the other of the two overlapping edges 62 is disposed on the bottom surface of the second connecting portion 2222. In this way, it is convenient for the second fastener F to penetrate from bottom to top to detachably connect the water baffle 6 to the evaporator assembly 2, and the installation efficiency is high. It can be understood that when the water receiving tray 5 collects the condensed water of the evaporator 21, a certain gap needs to be provided between the two to allow the condensed water to drip into the water storage tank 5a. And the air supply needs to be exchanged heat with the evaporator 21 before being sent out. The existence of these gaps will cause a part of the air supply to overflow from the gaps, resulting in a decrease in the final air volume. In this embodiment, the bottom of the evaporator 21 is wrapped with a water baffle 6. In this way, the air supply cannot pass through the part of the evaporator 21 located in the water storage tank 5a, so that most of the air supply can pass through the part of the evaporator 21 away from the water storage tank 5a for heat exchange, and the heat exchange effect is good.

[0063] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 8 , one of the mounting ears 31a is formed with a hook G opening towards the mounting portion 221, and a part of one of the mounting portions 221 is inserted into the hook G. Exemplarily, the mounting ear 31a on the right side of the bottom plate 31 is formed with a hook G opening towards the mounting portion 221 of the right support plate 22b. The hook G can be engaged with the folded edge 221b of the mounting portion 221 of the left support plate 22a. In this way, the bottom plate 31 of the electronic control box 3 can not only be connected to the evaporator assembly 2 through the fourth fastener D, but also under the action of gravity, the hook G on the mounting ear 31a on the right side of the bottom plate 31 can hook the folded edge 221b of the mounting portion 221 of the right support plate 22b. In this way, when disassembling, the fourth fastener D can be unscrewed without holding the electronic control box 3 by hand, and the installation and disassembly efficiency is high.

[0064] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 8, wherein another mounting ear 31a and another mounting portion 221 are connected by a buckle H and a slot J. Exemplarily, the mounting ear 31a on the left side of the bottom plate 31 is formed with a slot J that runs through the top and bottom directions, and the folded edge 221b of the mounting portion 221 of the left support plate 22a is formed with a buckle H that extends downward, so that under the action of gravity, the bottom plate 31 can be hung on the buckle H through the slot J, so that the electric control box 3 can be quickly installed, and when disassembling, the fourth fastener D can be screwed out without holding the electric control box 3 by hand, which is efficient.

[0065] For example, in one embodiment, one of the mounting ears 31a is formed with a hook G opening toward the mounting portion 221, a portion of one mounting portion 221 is inserted into the hook G, and another mounting ear 31a and another mounting portion 221 are engaged with each other through a buckle H and a slot J. In this way, the connection strength between the electric control box 3 and the evaporator assembly 2 can be further increased, and the stability is good.

[0066] In one embodiment, please refer to Figure 1 The housing 1 includes an annular enclosure 3213, which forms a receiving cavity 13a and an air outlet connected to the receiving cavity 13a.

Exemplarily, the annular enclosure 3213 includes a left enclosure 32131, a right enclosure 32132, a front enclosure 32133 and a rear enclosure 32134. The left enclosure 32131 and the right enclosure 32132 are spaced apart in the left-right direction, the front enclosure 32133 and the rear enclosure 32134 are connected thereto in the front-to-back direction to form a accommodating chamber 13a, the top enclosure 11 is connected to the top side of the annular enclosure 3213, the front enclosure 32133 is formed with an air outlet running through the front-to-back direction thereof, and the evaporator assembly 2 can be disposed in the accommodating chamber 13a near the air outlet, so that the supply air can be delivered out of the casing 1 through the air outlet after heat exchange through the evaporator 21.

[0067] In one embodiment, please refer to Figure 1 and Figure 7 The air conditioning device 100 includes a pre-assembled fan 72 assembly 7, and the fan 72 assembly 7 includes a partition 71, a fan 72 and a motor 73.
