[0036] Embodiment 1

[0037] In view of the above problems, an embodiment of the present application provides a modular indoor air conditioner that can fully utilize space to achieve easy disassembly and assembly of functional modules.

[0038] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0039] See also Figure 1 , Figure 1 This application example shows Figure 1 1 is a schematic diagram of the components of a modular indoor air conditioner shown in an embodiment of the present application, wherein the module components include: a heat exchange module 10, a drainage module 30, a fan module 20, an independent water receiving tray 50 and a back plate 40. There is also a three-way valve mounting member 403 disposed on the back plate 40.

[0040] See also Figure 2 , Figure 2 : is a schematic diagram of the structure of the back plate 40 shown in the embodiment of the present application. In the figure, the back plate 40 includes a plane end 401 and a curved support end 402, and the curved support end 402 is arranged below the plane end 401. The curved surface shape of the curved support end 402 is adapted to the shape of the air outlet structure at the bottom of the fan module 20, and a fan fixing part 4021 is arranged on the curved support end 402. The plane end 401 is provided with: a heat exchange fixing part 4011 and a drainage fixing part 4012. The heat exchange fixing part 4011 is a screw hole base, and the drainage fixing part 4012 is a fixed beam with a screw hole, and the heat exchange fixing part 4011 is arranged above the drainage fixing part 4012. A slot 40121 that passes through from top to bottom is arranged on the fixed beam.

[0041] See also Fig.14 , Fig.14 : is a schematic diagram of the structure of the fan module 20 shown in the embodiment of the present application. The main body of the fan module 20 is a crossflow fan 204, the top of the crossflow fan is a curved surface, the bottom of the crossflow fan 204 is an air outlet structure, one end of the crossflow fan 204 is provided with a motor, the motor is provided with a motor pressure cover 202, and the other end of the crossflow fan 204 is provided with an air duct end cover 203. The air outlet structure is a curved surface, and needs to be supported by a structure adapted to the curved support end 402 to facilitate fixation and stable installation of the fan module 20.

[0042] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 3 is a schematic diagram of the structure of the fan module 20 installed on the back plate 40 shown in the embodiment of the present application, Figure 4 This application example shows Figure 3 AA section view, Figure 5 This application example shows Figure 3 BB section view, Figure 6 This application example shows Figure 3 It can be seen that the fan module 20 is fixed by the fan fixing portion 4021 on the curved support end 402, and the screw hole bases that are adapted to the air outlet structure at the bottom of the fan module 20 can fix and lift the fan module 20. Figure 3It can be seen that the bottom of the fan module is a spiral opening-shaped air outlet structure. The spiral here refers to the structure in which the opening of the air outlet structure gradually expands. That is, starting from the joint between the fan module and the back plate, the air outlet structure with a spiral opening expands, and its bottom is in an arc shape. The orientation of the screw hole base is adapted to the arc bottom surface of the air outlet structure, which can provide a stable fixed support effect for the fan module. At the same time, a mounting plug 201 is provided on the fan module 20, and the mounting plug 201 is adapted to the slot 40121 on the fixing beam of the drainage fixing part 4012 on the back plate 40, so that when the fan module 20 is fixed at the curved support end 402, it can also be fixed by the slot 40121, which plays a stabilizing role.

[0043] See also Figure 8 , Figure 8 It is a side view of the pipeline valve of the heat exchange module 10 shown in the embodiment of the present application. In the figure, it can be seen that the three-way valve 101 and the heat exchanger pipeline 102 are connected together through the back plate 40. The heat exchanger 103 forms a refrigerant circuit through the heat exchanger pipeline 102 and the air conditioner outdoor unit, and liquid and gaseous refrigerants circulate in the refrigerant circuit. The curved support end 402 of the back plate 40 forms an inner space on the other side relative to the fan fixing part 4021 to accommodate the heat exchanger pipeline 102.

[0044] See also Fig.13 , Fig.13 : is a schematic diagram of the structure of the heat exchange module 10 shown in the embodiment of the present application.

A mounting bracket is provided behind the heat exchanger 103, and the mounting bracket is adapted to the base. The heat exchanger 103 is a curved shape. Although it is mounted on the heat exchange fixing part 4011 by the mounting bracket, the center of gravity of the heat exchange module 10 is still on the main body of the heat exchanger 103, so the bottom of the heat exchanger 103 needs to overlap with the top of the fan module 20 to ensure the stability of the installation. The motor pressure cover 202 and the air duct end cover 203 of the fan module 20 are adapted to the bottom of the heat exchanger 103.

[0045] See also Fig.11 , Fig.11 Schematic diagram of the drainage module 30 and the independent drainage pan shown in the embodiment of the present application. The drainage fixing part 4012 is a fixed beam with screw holes, and a positioning block is provided on the fixed beam. It can be seen that the drainage module 30 is provided with a positioning port 301, and the positioning port 301 is adapted to the positioning block, so that the drainage module 30 can be quickly installed on the fixed beam of the back plate 40 and the screw holes are aligned. The drainage module 30 is connected to the independent drainage pan through the guide pipe 302 to collect condensed water, and the guide pipe 302 is also accommodated in the inner space formed by the curved support end 402.

[0046] In the embodiment of the present application, the functional components of the air conditioner are modularized into a heat exchange module 10, a drainage module 30 and a fan module 20. The back plate 40 is used as the installation base of each module, the fan module 20 is installed with the curved support end 402, the air outlet structure of the fan module 20 is supported, and the heat exchange module 10 and the drainage module 30 are installed on the flat end 401 of the back plate 40 through the heat exchange fixing part 4011 and the drainage fixing part 4012, and the heat exchange module 10 is overlapped on the fan module 20. In this way, the air conditioner is divided into modules according to function, and the modules are assembled and installed together with the back plate 40 as the base, so as to fully utilize the space and facilitate disassembly and assembly. In this way, the modular air conditioner with the back plate 40 as the base solves the problem of complicated maintenance and cleaning operations of the traditional bottom shell mode air conditioner, reducing the cost and difficulty.

[0047] Embodiment 2

[0048] During the disassembly of the air conditioner, the refrigerant flowing in the heat exchange module 10 needs to be collected first. However, the traditional solution requires staff to go outdoors and close the refrigerant valve on the outdoor unit side to collect the refrigerant, which is very troublesome. The three-way valve 101 of the present application is set on the indoor unit, which can intercept and collect the refrigerant in the heat exchanger 103 indoors.

[0049] See also Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the back side of the back plate 40 when the heat exchange module 10 shown in the embodiment of the present application is installed on the back plate 40, Figure 8 It is a side view of the pipeline valve of the heat exchange module 10 shown in the embodiment of the present application. The heat exchange module 10 includes: a three-way valve 101, a heat exchanger pipeline 102 and a heat exchanger 103. The heat exchanger 103 forms a refrigerant circuit through the heat exchanger pipeline 102 and the air conditioner outdoor unit, and the three-way valve 101 is installed on the heat exchanger pipeline 102. A three-way valve mounting part 403 is provided on the curved support end 402, and the three-way valve mounting part 403 is adapted to the three-way valve 101. The curved support end 402 forms an inner space on the other side relative to the fan fixing part 4021 to accommodate the heat exchanger pipeline 102.

[0050] See also Fig. 9 and Fig.10 , Fig. 9 This application example shows Figure 8 DD section view, Fig.10It is an exploded view of the three-way valve 101 shown in the embodiment of the present application. The three-way valve 101 includes: a first valve port 1013, a second valve port 1014 and a third valve port. In actual use, two three-way valves 101 will be set to be respectively set on the two heat exchanger pipelines 102 of the refrigerant circuit. The two heat exchanger pipelines 102 are respectively the refrigerant liquid pipe and the refrigerant gas collecting pipe, that is, the liquid refrigerant flows in the refrigerant liquid pipe, and the gaseous refrigerant flows in the refrigerant collecting pipe. The two ends of the two pipelines are connected to the heat exchanger 103 and the air conditioner outdoor unit. In this embodiment, a split-type four-conducting port structure is adopted to realize the function of the three-way valve 101, so it is equivalent to having two third valve ports 1015. The valve structure of this embodiment is a split structure. Through the combination of two connecting ports 1016, the four connecting ports are connected, and the inner bolt 1012 is used as a valve to realize the shutoff check. The valve of this embodiment is also provided with a mounting wing 1017, and the valve is mounted on the three-way valve mounting member 403 through the mounting wing 1017. Such a valve design can be separated and disassembled more conveniently when the heat exchange module is disassembled. The first valve port 1013 and the second valve port 1014 are arranged on the heat exchanger pipeline 102, that is, Fig. 9 In the figure, the first valve port 1013 and the second valve port 1014 are two openings that are not sealed by the inner bolt 1012, and the two openings are connected to the heat exchanger pipeline 102. By screwing in the inner bolt 1012 close to the first valve port 1013, the first valve port 1013 can be cut off, and by screwing in the inner bolt 1012 close to the second valve port 1014, the second valve port 1014 can be cut off.

[0051] Generally speaking, to collect liquid refrigerant, the inner bolt 1012 in the three-way valve 101 on the refrigerant machine pipe is screwed in to cut off the flow of gaseous refrigerant in the refrigerant collecting pipe, and then the inner bolt 1012 on the refrigerant liquid pipe is unscrewed to open the third valve port. The refrigerant circuit of the entire air conditioner indoor and outdoor units is cut off, and the refrigerant can only flow out as liquid from the third valve port.

[0052] In an embodiment of the present application, a three-way valve 101 is provided at the indoor unit of the refrigerant circuit. By controlling the cutoff and conduction of the three-way valve 101, the refrigerant circuit is cut off, so that technicians can collect liquid refrigerant indoors, making the disassembly of the air conditioner more convenient without having to go outdoors to operate the refrigerant valve of the outdoor unit.

[0053] Embodiment 3

[0054] When the air conditioner is actually used, an air conditioner shell is also required. The air conditioner shell is connected to the back plate 40 to protect the heat exchange module 10, the drainage module 30, the fan module 20 and the independent drainage tray therein. The shape of the shell needs to be compatible with the module.

[0055] See also Fig.12 , Fig.12It is an installation side view of the modular indoor air conditioner shown in the embodiment of the present application. When the modular indoor air conditioner of the present application needs to be disassembled, the outer shell of the air conditioner is first removed, and it can be seen that the top of the fan module 20 overlaps with the bottom of the heat exchange module 10. After completing the indoor recovery of the refrigerant, disconnect the connection of the guide tube 302 between the drainage module 30 and the independent drainage tray, and then loosen the connection between the heat exchange module 10 and the heat exchange fixing part 4011. After disassembling the valve parts, the entire heat exchange module 10 can be removed. The heat exchange module 10 is connected to an independent water receiving tray 50, which can be disassembled separately. Next, disassemble the drainage module 30, disassemble and separate the drainage module 30 from the fixing beam of the drainage fixing part 4012, and finally loosen the screws of the fan module 20 and the fan fixing part 4021 at the curved support end 402 of the back plate 40, and then remove the fan module 20 in the direction of the installation plug 201 to achieve the disassembly of each module.

[0056] The modules of the modular air conditioner are installed together by making full use of the space, and are also very convenient to disassemble in sequence. When problems occur in different functions of the air conditioner, it is also very convenient to conduct detailed inspection, replacement and repair according to the modules.
