Description

Technical Field

[0001] The invention relates to the technical field of air conditioning equipment. Background Art

[0002] For integrated heat pump air conditioning units, there are two types: air conditioning with fresh air function and air conditioning without fresh air function. Users can choose the corresponding air conditioning equipment according to their needs. For air conditioning with fresh air function, the equipment and structure required for fresh air can be set in the air conditioning unit to provide fresh air for the room, and it has its own exhaust vents to discharge excess indoor air to the outside. For air conditioning without fresh air function, since the fresh air function is not required, there is no need to set the equipment and structure required for fresh air.

[0003] However, due to the large size and weight of the integrated heat pump air conditioner unit, it is very difficult to install the air conditioner. Moreover, after the air conditioner is installed, if the user's needs change, the air conditioner with the corresponding function needs to be replaced, which will increase the user's cost. Therefore, there is an urgent need for an air conditioner that can reduce the difficulty of installation, facilitate users to adjust the structure and function of the air conditioner according to their needs, and reduce user costs. Summary of the invention

[0004] In view of the above problems in the prior art, the present application provides an air conditioner that can reduce the difficulty of installation, facilitate users to adjust the structure and function of the air conditioner according to their needs, and reduce user costs.

[0005] The present application provides an air conditioner, comprising: a shell, the shell having a first installation space, a second installation space and a third installation space, the third installation space being arranged between the first installation space and the second installation space; a first heat exchanger, the first heat exchanger being installed in the first installation space, and being used for heat exchange with indoor air; a second heat exchanger, the second heat exchanger being installed in the second installation space, and being used for heat exchange with outdoor air; an intermediate module, the intermediate module being arranged in the third installation space, being detachably connected to the third installation space, and being used for controlling air exchange between indoor and outdoor areas.

[0006] With the above structure, by setting the intermediate module, the intermediate module is detachably connected to the third installation space. Since the intermediate module can control the air exchange between indoor and outdoor, the user can adjust the function of the air conditioner according to the fresh air demand. That is, when the user's fresh air demand changes, the intermediate module with corresponding functions can be replaced to control whether and how the air between indoor and outdoor is exchanged, thereby changing the fresh air state to upgrade the air conditioner. In this way, the application range of the air conditioner can be improved and the installation and use cost of the user can be reduced.

[0007] In some embodiments, the first installation space has a first air inlet and a first air outlet, the second installation space has a second air inlet and a second air outlet, and the third installation space has a third air inlet and a fourth air inlet. The third installation space is connected to the first installation space via a first connecting port, and the third installation space is connected to the second installation space via a second connecting port. The first air inlet, the first air outlet, and the third air inlet are connected to indoor spaces, and the second air inlet, the second air outlet, and the fourth air inlet are connected to outdoor spaces.

[0008] In some embodiments, the air conditioner also includes: a first fan, which is installed in the first installation space, driving the indoor air to enter the first installation space from the first air inlet, pass through the first heat exchanger, and then be discharged from the first air outlet; a second fan, which is installed in the second installation space, driving the outdoor air to enter the second installation space from the second air inlet, pass through the second heat exchanger, and then be discharged from the second air outlet.

[0009] With the above structure, the indoor air is driven by the first fan to enter the first installation space from the first air inlet, pass through the first heat exchanger, and then be discharged from the first air outlet, thereby adjusting the indoor air temperature. The outdoor air is driven by the second fan to enter the second installation space from the second air inlet, pass through the second heat exchanger, and then be discharged from the second air outlet, thereby achieving heat exchange between indoor air and outdoor air.

[0010] In some embodiments, the first air outlet is located at the top of the housing.

[0011] With the above structure, by arranging the first air outlet at the top of the shell, the air conditioner can be conveniently connected to the indoor air duct so as to accurately supply air through the air duct.

[0012] In some embodiments, the air conditioner further includes an air filter, and the air filter is disposed in the first installation space and located between the first air inlet, the first connecting port, and the first air outlet.

[0013] With the above structure, by installing an air filter in the first installation space, the air entering the room through the first installation space can be filtered.

[0014] In some embodiments, the intermediate module is a sealing module or a fresh air module; the sealing module is used to close the third air inlet and the fourth air inlet, and is also used to close at least one of the first connecting port and the second connecting port; the fresh air module is used to drive the indoor air to be discharged to the outside through the third air inlet and the second air outlet, and is also used to drive the outdoor air to enter the room through the fourth air inlet and the first air outlet.

[0015] With the above structure, users can choose to install the sealing module in the third installation space according to their needs to isolate the indoor air from the outdoor air. Alternatively, they can choose to install the fresh air module in the third installation space to enable the air conditioner to have a fresh air function. In this way, the flexibility of the air conditioner can be improved, and users can flexibly adjust the functions of the air conditioner according to their needs, thereby reducing the cost of users.

[0016] In some embodiments, the sealing assembly includes: a first sealing plate, which is located at a corresponding position of the third air inlet and is used to close the third air inlet; a second sealing plate, which is located at a corresponding position of at least one of the first connecting port and the second connecting port and is used to close the first connecting port and the second connecting port respectively.

[0017] With the above structure, after the sealing assembly is installed in the third installation space, the third air inlet can be closed by the first sealing plate, thereby preventing indoor air from entering the third installation space through the third air inlet. The first connecting port or the second connecting port can be closed by the second sealing plate, thereby preventing the first installation space from being connected to the second installation space, and further preventing indoor and outdoor from being connected through the third installation space.

[0018] In some embodiments, the fresh air module includes: a first air valve blade, when the first air valve blade rotates to a first position, the third air inlet is separated from the first connecting port, the fourth air inlet is connected to the first connecting port, and the third air inlet is connected to the second connecting port; when the first air valve blade rotates to a second position, the third air inlet and the first connecting port are separated from the fourth air inlet and the second air outlet; a third fan, when the first air valve blade is located at the first position, the third fan is used to drive outdoor air to be discharged from the fourth air inlet and the first connecting port into the first installation space.

[0019] With the above structure, by rotating the first air valve blade to the first position, the third air inlet is separated from the first connecting port, and the fourth air inlet is connected to the first connecting port, so that outdoor air can enter the first installation space through the fourth air inlet and the first connecting port under the drive of the third fan and then enter the room. The third air inlet can also be connected to the second connecting port, so that the indoor air can enter the second installation space through the third air inlet and the second connecting port, and then be discharged to the outside under the drive of the second fan. In this way, fresh air circulation between the outdoors and the indoors can be achieved. When the fresh air function does not need to be turned on, the first air valve blade can also be rotated to the second position to separate the third air inlet, the first connecting port and the fourth air inlet, the second air outlet, so that the indoor and outdoor areas can be isolated to avoid air exchange.

[0020] In some embodiments, the fresh air module includes: a third heat exchanger, the third heat exchanger having a first heat exchange channel and a second heat exchange channel, the first heat exchange channel connects the fourth air inlet and the first connecting port, the second heat exchange channel connects the third air inlet and the second connecting port, and the air in the first heat exchange channel exchanges heat with the air in the second heat exchange channel.

[0021] With the above structure, by setting the third heat exchanger in the fresh air module, the indoor air can be discharged to the outside through the third air inlet, the second connecting port, the second heat exchange channel and the second air outlet. The outdoor air can be discharged to the indoor through the fourth air inlet, the first heat exchange channel, the first connecting port and the first air outlet. As a result, when the outdoor air is exchanged with the indoor air for fresh air, it can exchange heat when flowing through the first heat exchange channel and the second heat exchange channel in the third heat exchanger, so that heat recovery can be performed, thereby reducing the energy consumption of the air conditioner and reducing the cost of use.

[0022] In some embodiments, the fresh air module further includes a second air valve blade, and when the second air valve blade rotates to a third position, the fourth air inlet is opened, and when the second air valve blade rotates to a fourth position, the fourth air inlet is closed.

[0023] With the above structure, by setting the second air valve blade, the second air valve blade can be closed when the air conditioner does not need to use the fresh air function, thereby avoiding air exchange between indoor and outdoor.

[0024] These and other aspects of the invention will become apparent from the following description of the embodiment(s). BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Below, in conjunction with the accompanying drawings, a possible embodiment of the air conditioner 10 in the present application is exemplarily described.

[0055] like Figure 1 , Figure 4-Figure 6 , Figure 9-11 , Figure 16-Figure 18 As shown, the air conditioner 10 in the present application includes a housing 100, a first heat exchanger 220, a second heat exchanger 320 and an intermediate module. The housing 100 has a first installation space 110, a second installation space 120 and a third installation space 130, and the third installation space 130 is arranged between the first installation space 110 and the second installation space 120. The first heat exchanger 220 is installed in the first installation space 110 for heat exchange with indoor air. The second heat exchanger 320 is installed in the second installation space 120 for heat exchange with outdoor air. The intermediate module is arranged in the third installation space 130, and is detachably connected to the third installation space 130, and is used to control the air exchange between indoor and outdoor.

[0056] As described above, by setting the intermediate module, the intermediate module is detachably connected to the third installation space 130. Since the intermediate module can control the air exchange between indoor and outdoor, the user can adjust the function of the air conditioner 10 according to the needs. That is, when the user's fresh air demand changes, the intermediate module with corresponding functions can be replaced to control whether and how the air between indoor and outdoor is exchanged, thereby changing the fresh air state to upgrade the air conditioner. In this way, the application scope of the air conditioner 10 can be improved and the installation and use cost of the user can be reduced.

[0057] In some embodiments, Figure 4-Figure 6 , Figure 9-11 , Figure 16-Figure 18As shown, the first installation space 110 has a first air inlet 111 and a first air outlet 112, the second installation space 120 has a second air inlet 121 and a second air outlet 122, and the third installation space 130 has a third air inlet 131 and a fourth air inlet 132. The third installation space 130 is connected to the first installation space 110 via a first connecting port 113, and the third installation space 130 is connected to the second installation space 120 via a second connecting port 123. The first air inlet 111, the first air outlet 112, and the third air inlet 131 are connected to the indoor space, and the second air inlet 121, the second air outlet 122, and the fourth air inlet 132 are connected to the outdoors.

[0058] In some embodiments, Figure 4 , Figure 6 , Fig. 9 , Fig.11 , Fig.16 , Fig.18 As shown, the air conditioner 10 further includes a first fan 210 and a second fan 310. The first fan 210 is installed in the first installation space 110, driving the indoor air to enter the first installation space 110 from the first air inlet 111, pass through the first heat exchanger 220, and then be discharged from the first air outlet 112. The second fan 310 is installed in the second installation space 120, driving the outdoor air to enter the second installation space 120 from the second air inlet 121, pass through the second heat exchanger 320, and then be discharged from the second air outlet 122. Thus, the indoor air is driven by the first fan 210 to enter the first installation space 110 from the first air inlet 111, pass through the first heat exchanger 220, and then be discharged from the first air outlet 112, thereby achieving the indoor air temperature adjustment. The outdoor air is driven by the second fan 310 to enter the second installation space 120 from the second air inlet 121, pass through the second heat exchanger 320, and then be discharged from the second air outlet 122, thereby achieving the heat exchange between the indoor air and the outdoor air.

[0059] In some embodiments, Figure 3 , Figure 4 , Figure 6 , Fig. 9 , Fig.11 , Fig.16 , Fig.18 As shown, the first air outlet 112 is located at the top of the housing 100. Thus, by arranging the first air outlet 112 at the top of the housing 100, the air conditioner 10 can be conveniently connected to the indoor air duct so as to accurately deliver air through the air duct.

[0060] In some embodiments, Figure 4-Figure 6 , Figure 9-11 , Figure 16-Figure 18As shown, the air conditioner 10 further includes an air filter 230, which is disposed in the first installation space 110, and is located between the first air inlet 111, the first communication port 113, and the first air outlet 112. Thus, by installing the air filter 230 in the first installation space 110, the air entering the room through the first installation space 110 can be filtered.

[0061] In some embodiments, Figure 4-Figure 22 As shown, the middle module is a sealing module 400 or a fresh air module. The sealing module 400 is used to close the third air inlet 131 and the fourth air inlet 132, and is also used to close at least one of the first connecting port 113 and the second connecting port 123. The fresh air module is used to drive the indoor air to be discharged to the outside through the third air inlet 131 and the second air outlet 122, and is also used to drive the outdoor air to be discharged to the indoor through the fourth air inlet 132 and the first air outlet 112. Therefore, the user can choose to install the sealing module 400 in the third installation space 130 according to the needs, so that the indoor air is isolated from the outdoor air. Alternatively, the fresh air module is selected to be assembled in the third installation space 130, so that the air conditioner 10 has a fresh air function. In this way, the flexibility of the air conditioner 10 can be improved, so that the user can flexibly adjust the function of the air conditioner 10 according to the needs, thereby reducing the cost of the user.

[0062] In some embodiments, Figure 7 , Figure 8 As shown, the sealing assembly includes a first sealing plate 410 and a second sealing plate 420. The first sealing plate 410 is located at a position corresponding to the third air inlet 131, and is used to close the third air inlet 131. The second sealing plate 420 is located at a position corresponding to at least one of the first connecting port 113 and the second connecting port 123, and is used to close the first connecting port 113 and the second connecting port 123 accordingly. Thus, after the sealing assembly is installed in the third installation space 130, the third air inlet 131 can be closed by the first sealing plate 410, thereby preventing indoor air from entering the third installation space 130 through the third air inlet 131. The first connecting port 113 or the second connecting port 123 can be closed by the second sealing plate 420, thereby preventing the first installation space 110 from being connected to the second installation space 120, and further preventing the indoor and outdoor from being connected through the third installation space 130.

[0063] In some embodiments, the first sealing plate 410 and the second sealing plate 420 may be two separate plates, or may be a single plate. Figure 7 , Figure 8 As shown, it is formed by bending a plate, but this is not limited to this.

[0064] In some embodiments, Figure 9-Figure 15The fresh air module shown includes a first air valve blade 530 and a third fan 520. When the first air valve blade 530 rotates to the first position A, the third air inlet 131 is separated from the first connecting port 113, the fourth air inlet 132 is connected to the first connecting port 113, and the third air inlet 131 is connected to the second connecting port 123. When the first air valve blade 530 rotates to the second position B, the third air inlet 131 and the first connecting port 113 are separated from the fourth air inlet 132 and the second air outlet 122. When the first air valve blade 530 is located at the first position A, the third fan 520 is used to drive the outdoor air to be discharged from the fourth air inlet 132 and the first connecting port 113 into the first installation space 110. Thus, by rotating the first air valve blade 530 to the first position A, the third air inlet 131 is separated from the first connecting port 113, and the fourth air inlet 132 is connected to the first connecting port 113, so that outdoor air can enter the first installation space 110 through the fourth air inlet 132 and the first connecting port 113 under the drive of the third fan 520, and then enter the room. The third air inlet 131 can also be connected to the second connecting port 123, so that the indoor air enters the second installation space 120 through the third air inlet 131 and the second connecting port 123, and then is discharged to the outside under the drive of the second fan 310. Thus, fresh air circulation between the outside and the inside can be achieved. When the fresh air function does not need to be turned on, the first air valve blade 530 can also be rotated to the second position B, so as to separate the third air inlet 131, the first connecting port 113 and the fourth air inlet 132, and the second air outlet 122, so as to isolate the indoor and outdoor to avoid air exchange.

[0065] In some embodiments, Figure 16-Figure 22 As shown, the fresh air module includes a third heat exchanger 630, and the third heat exchanger 630 has a first heat exchange channel and a second heat exchange channel. The first heat exchange channel is connected to the fourth air inlet 132 and the first connecting port 113, and the second heat exchange channel is connected to the third air inlet 131 and the second connecting port 123. The air in the first heat exchange channel and the air in the second heat exchange channel can exchange heat. Therefore, by arranging the third heat exchanger 630 in the fresh air module, the indoor air can be discharged to the outside through the third air inlet 131, the second connecting port 123, the second heat exchange channel and the second air outlet. The outdoor air can be discharged to the indoor through the fourth air inlet 132, the first heat exchange channel, the first connecting port 113 and the first exhaust port. Therefore, when the outdoor air is exchanged with the indoor air for fresh air, it can exchange heat when it flows through the first heat exchange channel and the second heat exchange channel in the third heat exchanger 630, so that heat recovery can be performed, thereby reducing the energy consumption of the air conditioner 10 and reducing the use cost.

[0066] In some embodiments, Fig.17 , Figure 20-Figure 22As shown, the fresh air module further includes a second air valve blade 640. When the second air valve blade 640 rotates to the third position C, the fourth air inlet 132 is opened. When the second air valve blade 640 rotates to the fourth position D, the fourth air inlet 132 is closed. Thus, by providing the second air valve blade 640, the second air valve blade 640 can be closed when the air conditioner 10 does not need to use the fresh air function, thereby avoiding air exchange between indoor and outdoor.

[0067] In some embodiments, the first heat exchanger 220 is used for heat dissipation, that is, heating the air; the second heat exchanger 320 is used for heat absorption, that is, absorbing heat from the air. Alternatively, the second heat exchanger 320 is used for heat dissipation, that is, heating the air; the first heat exchanger 220 is used for heat absorption, that is, absorbing heat from the air.

[0068] The above contents are combined with the accompanying drawings to exemplarily describe possible embodiments of the air conditioner 10 in the present application. Next, combined with the accompanying drawings, the specific structure of the air conditioner 10 in the present application is described in detail in a specific embodiment.

[0071] like Figure 1-Figure 6 As shown, the air conditioner 10 in the present application includes a housing 100 and an indoor circulation module 200, an outdoor circulation module 300 and a sealing module 400 (intermediate module) arranged in the housing 100. Among them, the indoor circulation module 200 is used to drive the indoor air circulation, heat the indoor air, and increase the indoor temperature. The outdoor circulation component is used to drive the outdoor air circulation and absorb the heat in the outdoor air. The intermediate module is arranged between the indoor circulation module 200 and the outdoor circulation module 300. The intermediate module in Example 1 is a sealing component, which is used to isolate the indoor circulation module 200 from the outdoor circulation to avoid communication between the indoor and outdoor.

[0072] like Figure 1-Figure 6As shown, the housing 100 is in the shape of a cuboid, and the housing 100 is not divided into three parts in the up-down direction, forming a first installation space 110, a second installation space 120 and a third installation space 130 in the shape of a cuboid. Among them, the first installation space 110 is located in the upper position of the housing 100, and is used to install the indoor circulation module 200. The second installation space 120 is located in the lower position of the housing 100, and is used to install the outdoor circulation module 300. The third installation space 130 is located between the first installation space 110 and the second installation space 120, and is used to install the intermediate module.

[0073] like Figure 2-Figure 6 As shown, a first air inlet 111 is provided on the housing at the left and right ends of the first installation space 110, which is used to communicate with the room, so that the air in the room can enter the first installation space 110 through the first air inlet 111. A first air outlet 112 is provided on the housing at the top middle position of the first installation space 110, and the first air outlet 112 is used to connect with the indoor air duct, so that the air with adjusted temperature can be accurately transported to the desired position through the air duct. A first connecting port 113 is provided at the bottom of the first installation space 110 near the left and right ends, and the first connecting port 113 is used to communicate with the third installation space 130.

[0074] like Figure 4-Figure 6As shown, the indoor circulation module 200 includes a first fan 210, a first heat exchanger 220, an air filter 230 and an electric heater 240. The first fan 210 is installed in the first installation space 110, located in the middle of the first installation space 110, and the air outlet of the first fan 210 is connected to the first air outlet 112. The first heat exchanger 220 is a dual-mode heat exchanger, that is, when the indoor temperature needs to be increased, the first heat exchanger 220 is a condenser, and the coolant condenses and releases heat in the first heat exchanger 220, and can exchange heat with the air passing through the first heat exchanger 220 to increase the temperature of the air. When the indoor temperature needs to be reduced, the first heat exchanger 220 is an evaporator, and the coolant evaporates and absorbs heat in the first heat exchanger 220, and can exchange heat with the air passing through the first heat exchanger 220 to reduce the temperature of the air. Two first heat exchangers 220 are provided, which are symmetrically arranged at the left and right sides of the first fan 210. Two air filters 230 are provided, symmetrically arranged at the left and right sides of the first fan 210, respectively located on the side of the two first heat exchangers 220 away from the first fan 210. The two first connecting ports 113 are respectively located between the corresponding first air inlet 111 and the air filter 230. The electric heater 240 is arranged on the first air outlet 112, and can heat the air when the air is discharged from the first air outlet 112. Therefore, when the first fan 210 is working, the air entering the first installation space 110 through the first air inlet 111 and the first connecting port 113 can pass through the air filter 230 for filtering, and then be discharged from the first air outlet 112 after heat exchange and temperature increase through the first heat exchanger 220 and the electric heater 240.

[0075] like Figure 6 As shown, the second installation space 120 has a second air inlet 121 and a second air outlet 122. The second air inlet 121 and the second air outlet 122 are arranged at the rear side of the housing 100 so that the air conditioner 10 can be connected to the outside after being installed against the wall indoors. There are two second air inlets 121, which are respectively located on the left and right sides of the second air outlet 122. Thus, outdoor air can enter the second installation space 120 through the two second air inlets 121 and be discharged through the second air outlet 122. A second connecting port 123 is respectively arranged at the top of the second installation space 120 near the left and right ends, and the second installation space 120 can be connected to the third installation space 130 through the second connecting port 123.

[0076] like Figure 4-Figure 6As shown, the outdoor circulation module 300 is arranged in the second installation space 120, and includes a second fan 310 and a second heat exchanger 320. The second fan 310 is installed in the middle position of the second installation space 120, at a position corresponding to the second air outlet 122. Two second heat exchangers 320 are provided, which are respectively located between the two second air inlets 121, the second connecting port 123 and the second air outlet 122, so that when the outdoor air enters the second installation space 120 from the second air inlet 121 and the second connecting port 123, it needs to pass through the second heat exchanger 320, exchange heat with the second heat exchanger 320, and then be discharged from the second air outlet 122. The second heat exchanger 320 is a dual-mode heat exchanger, that is, when it is necessary to cool the room, the second heat exchanger 320 is a condenser, and the coolant condenses and releases heat in the second heat exchanger 320, and can exchange heat with the air passing through the second heat exchanger 320, and dissipate heat into the air. When the indoor temperature needs to be raised, the second heat exchanger 320 is an evaporator, and the coolant evaporates and absorbs heat in the second heat exchanger 320, and can exchange heat with the air passing through the second heat exchanger 320, so as to absorb the heat in the air. Therefore, when the second fan 310 is working, the air entering the second installation space 120 through the second air inlet 121 and the second connecting port 123 can pass through the second heat exchanger 320 for heat exchange and temperature reduction, and then be discharged from the second air outlet 122.

[0077] like Figure 4-Figure 6 As shown, the outdoor circulation module 300 also includes a compressor 330, an electric control box 340, a frequency converter 350, an electronic expansion valve, a reversing valve and other components. The compressor 330 is electrically connected to the electric control box 340 and the frequency converter 350, and the compressor 330 can be controlled by the electric control box 340 and the frequency converter 350. The compressor 330, the first heat exchanger 220, and the second heat exchanger 320 are connected by pipelines, so that the coolant can circulate in the compressor 330, the first heat exchanger 220, and the second heat exchanger 320, so that the second heat exchanger 320 can release the heat in the first heat exchanger 220 after absorbing the heat in the outdoor air, so as to heat the indoor air.

[0078] like Figure 4-Figure 6As shown, a third air inlet 131 is provided on the housing 100 at the left and right ends of the third installation space 130, and the third air inlet 131 is connected to the indoor air, so that the indoor air can enter the third installation space 130 through the third air inlet 131. A fourth air inlet 132 is provided on the housing at the rear side of the third installation space 130, and the fourth air inlet 132 is connected to the outdoor air, so that the outdoor air can enter the third installation space 130 through the fourth air inlet 132. A mounting port 133 is provided on the housing at the front side of the third installation space 130, and the sealing module 400 can be installed in the third installation space 130 through the mounting port 133.

[0079] Figure 7 for Figure 4 Schematic diagram of the orthographic projection structure of the middle sealing module 400 in three directions; Figure 8 for Figure 4 Schematic diagram of the three-dimensional structure of the sealing module 400. Figure 4-Figure 8 As shown, the sealing module 400 includes a first sealing plate 410, a second sealing plate 420 and a third sealing plate 430. Among them, the first sealing plate 410 is located at a position corresponding to the third air inlet 131, and is used to close the third air inlet 131. The second sealing plate 420 is located at a position corresponding to the first connecting port 113, and is used to close the first connecting port 113. The third sealing plate 430 is located at a position corresponding to the installation port 133, and is used to close the installation port 133. Specifically, the first sealing plate 410 and the second sealing plate 420 are integrally formed by sheet metal, and are L-shaped sheet metal parts, and the third sealing plate 430 is a rectangular plate-shaped component. Among them, the first sealing plate 410 and the second sealing plate 420 are provided with two, and are vertically fixedly connected to the third sealing plate 430 at both ends of the third sealing plate 430. The first sealing plate 410 is perpendicular to the corresponding second sealing plate 420, so that the sealing module 400 is adapted to the third installation space 130, and the overall shape is a rectangular parallelepiped. Therefore, after the sealing module 400 is installed in the third installation space 130, the third air inlet 131 can be closed by the first sealing plate 410, thereby preventing indoor air from entering the third installation space 130 through the third air inlet 131. The first connecting port 113 can be closed by the second sealing plate 420, thereby preventing the first installation space 110 from communicating with the third installation space 130, further preventing the first installation space 110 from communicating with the second installation space 120, and preventing indoor and outdoor communication through the third installation space 130.

[0080] In summary, the air conditioner 10 in Embodiment 1 can be installed with the sealing module 400 in the third installation space 130 after installation. Therefore, after the air conditioner 10 is turned on, the air in the room can be driven by the first fan 210 to enter the first installation space 110 from the first air inlet 111, filtered by the air filter 230, and then heat exchanged with the first heat exchanger 220, and discharged into the room from the first air outlet 112. When the performance of the first heat exchanger 220 cannot meet the heating demand, the electric heater 240 can also be controlled to work, so that after the air has completed the heat exchange with the first heat exchanger 220, it is heated by the electric heater 240 and then sent into the room.

[0081] The above content shows that when the user only needs to use the air conditioner 10 to adjust the temperature of the indoor air, the air conditioner 10 in the above embodiment 1 can be selected for installation. When the user needs the air conditioner 10 to provide a fresh air function, the air conditioner 10 in embodiment 1 cannot meet the user's needs. Next, taking embodiment 2 as an example, the specific structure of the air conditioner 10 with a fresh air function is described in detail.

[0082] Example 2

[0083] Fig. 9 This is a schematic diagram of the front orthographic projection structure showing the internal structure of the air conditioner 10 in Example 2; Fig.10 for Fig. 9 The left side orthographic structural diagram of the central air conditioner 10 showing the internal structure;

[0084] Fig.11 for Fig. 9 The three-dimensional structure diagram of the air conditioner 10 shows the internal structure. Figure 9-11 As shown, the difference between the air conditioner 10 in Example 2 and the air conditioner 10 in Example 1 is that the sealing module 400 in Example 1 is replaced with the first fresh air module 500 shown in Example 2. The housing 100, the indoor circulation module 200 and the outdoor circulation module 300 in Example 2 are exactly the same as those in Example 1, that is, after the sealing module 400 in Example 1 is pulled out from the third installation space 130, the first fresh air module 500 can be inserted into the third installation space 130 through the installation port 133, so as to obtain the following. Figure 9-11 The air conditioner 10 is shown. Therefore, the housing 100, the indoor circulation module 200 and the outdoor circulation module 300 in the second embodiment are not described in detail here.

[0085] Fig.12 for Fig. 9 A schematic diagram of the front orthographic projection structure of the first fresh air module 500 showing the internal structure; Fig.13 for Fig.12 A left side orthographic structural diagram showing the internal structure of the first fresh air module 500; Fig.14 for Fig.12 A top orthographic structural diagram showing the internal structure of the first fresh air module 500; Fig.15 for Fig.12 Schematic diagram of the three-dimensional structure of the first fresh air module 500. Figure 12-Figure 15 As shown, the first fresh air module 500 includes a first housing 510 and a third fan 520 and a first air valve blade 530 arranged in the first housing 510. The first housing 510 is a rectangular housing, which is adapted to the shape and size of the third installation space 130. A first interface 511 is respectively arranged at both ends of the first housing 510 at a position corresponding to the third air inlet 131. After the first fresh air module 500 is installed in the third installation space 130, the first interface 511 is connected to the third air inlet 131. A second interface 512 is respectively arranged at the top of the first housing 510 near both ends at a position corresponding to the first connecting port 113. After the first fresh air module 500 is installed in the third installation space 130, the second interface 512 is connected to the first connecting port 113. A third interface 513 is provided at the bottom of the first housing 510 at positions corresponding to the second communication opening 123, near both ends. After the first fresh air module 500 is installed in the third installation space 130, the third interface 513 is connected to the second communication opening 123. A first channel 514 is formed between the second interface 512 and the third interface 513 at both ends of the first housing 510. The first channel 514 extends in the left-right direction, and two first channel openings 515 are formed at the left and right ends of the first channel 514 at positions corresponding to the second interface 512 and the third interface 513.

[0086] like Fig.12 As shown, a rectangular space is formed between the first channel opening 515, the first interface 511, the second interface 512 and the third interface 513, and the first air valve blade 530 is located in the rectangular space. The first air valve blade 530 is connected to the electric actuator in a transmission manner and can rotate under the drive of the electric actuator. Specifically, when viewed from the front and rear directions, the first air valve blade 530 can be seen as follows: Fig.12The first damper blade 530 is shown in the first position A, that is, the first damper blade 530 is in a diagonal position, one end of the first damper blade 530 is connected to the connection position of the first interface 511 and the second interface 512, and the other end is connected to the connection position of the first channel opening 515 and the third interface 513. In this way, the second interface 512 can be connected to the first channel opening 515, the first interface 511 can be connected to the third interface 513, and the second interface 512 and the first channel opening 515 can be isolated from the first interface 511 and the third interface 513. The first damper blade 530 can also be driven by the electric actuator to rotate to the second position B, that is, the first damper blade 530 is in another diagonal position, one end of the first damper blade 530 is connected to the connection position of the second interface 512 and the first channel opening 515, and the other end is connected to the connection position of the first interface 511 and the third interface 513. Thus, the second interface 512 can be communicated with the first interface 511 , the first channel port 515 can be communicated with the third interface 513 , and the first interface 511 , the second interface 512 and the first channel port 515 , the third interface 513 can be isolated.

[0087] Two third fans 520 are provided, which are installed on the rear side wall of the first housing 510 and located between the two first passage openings 515. After the third fans 520 are turned on, the air at the rear side of the first housing 510 can be driven to pass through the third fans 520 and enter the first passage 514.

[0088] In summary, when the user needs to add a fresh air function, the sealing module 400 in Example 1 can be pulled out from the third installation space 130, and then the first fresh air module 500 in Example 2 can be inserted into the third installation space 130 from the installation port 133, so that the first interface 511 is connected to the third air inlet 131, the second interface 512 is connected to the first connecting port 113, the third interface 513 is connected to the second connecting port 123, and the third fan 520 is oriented toward the fourth air inlet 132. Thus, after the air conditioner 10 is turned on, it not only has the same function as the air conditioner 10 in Example 1, that is, the indoor air can be driven by the first fan 210 to enter the first installation space 110 from the first air inlet 111, filtered by the air filter 230, and then heat exchanged with the first heat exchanger 220, and finally discharged into the room from the first air outlet 112 through the electric heater 240. At the same time, the air conditioner 10 in Example 2 can also obtain a fresh air function through the first fresh air module 500.

[0089] Specifically, the electric actuator controls the rotation of the first air valve blade 530, so that the second interface 512 is connected to the first channel port 515, and the first interface 511 is connected to the third interface 513. In this way, the outdoor air can enter the third installation space 130 through the fourth air inlet 132, enter the first channel 514 under the drive of the third fan 520, and enter the first installation space 110 through the first channel port 515, the second interface 512, and the first connecting port 113, and pass through the air filter 230 and the first heat exchanger 220 under the drive of the first fan 210, and then be discharged into the room through the first air outlet 112, thereby providing fresh air for the room. In addition, the indoor air can also enter the second installation space 120 through the third air inlet 131, the first interface 511, the third interface 513, and the second connecting port 123, and after passing through the second heat exchanger 320 driven by the second fan 310, it is discharged to the outside through the second air outlet 122, thereby discharging the old air in the room to the outside. At the same time, the indoor exhaust gas can exchange heat with the second heat exchanger 320 to improve the energy efficiency of the whole machine.

[0090] The above content shows that when the user only needs the air conditioner 10 to provide a fresh air function, the air conditioner 10 in the above embodiment 2 can be selected for installation, or the sealing module 400 in the embodiment 1 can be replaced with the first fresh air module 500. When the user needs to recover the heat in the air discharged from the outside, the air conditioner 10 in the embodiments 1 and 2 cannot meet the user's needs. Next, taking the embodiment 3 as an example, the specific structure of another air conditioner 10 with a fresh air function is described in detail.

[0091] Example 3

[0092] Fig.16 This is a schematic diagram of the front orthographic projection structure showing the internal structure of the air conditioner 10 in Example 3; Fig.17 for Fig.16 The left side orthographic structural diagram of the central air conditioner 10 showing the internal structure;

[0093] Fig.18 for Fig.16 The three-dimensional structure diagram of the air conditioner 10 shows the internal structure. Figure 16-Figure 18As shown, the difference between the air conditioner 10 in Example 3 and the air conditioner 10 in Example 1 and Example 2 is that the sealing module 400 in Example 1 or the first fresh air module 500 in Example 2 is replaced with the second fresh air module 600 shown in Example 3. The housing 100, the indoor circulation module 200 and the outdoor circulation module 300 in Example 3 are exactly the same as those in Example 1 and Example 2, that is, after the sealing module 400 in Example 1 or the first fresh air module 500 in Example 2 is pulled out from the third installation space 130, the second fresh air module 600 can be inserted into the third installation space 130 through the installation port 133, so as to obtain the following. Figure 16-Figure 18 The air conditioner 10 is shown. Therefore, the housing 100, the indoor circulation module 200 and the outdoor circulation module 300 in the third embodiment are not described in detail here.

[0094] Fig.19 for Fig.16 A schematic diagram of the front orthographic projection structure of the second fresh air module 600 showing the internal structure; Fig. 20 for Fig.16 The left side orthographic structural diagram showing the internal structure of the second fresh air module 600; Fig.21 for Fig.16 A top orthographic structural diagram showing the internal structure of the second fresh air module 600; Fig. 22 for Fig.16 Schematic diagram of the three-dimensional structure of the second fresh air module 600. Figure 19-22As shown, the second fresh air module 600 includes a second housing 610, a fourth fan 620, a third heat exchanger 630 and a second air valve blade 640 arranged in the second housing 610. The second housing 610 is a rectangular housing, which is adapted to the shape and size of the third installation space 130. The second housing 610 is provided with a second channel 611 and a third channel 612 that are isolated from each other. The second channel 611 is provided with two, symmetrically arranged in the left and right parts of the second housing 610. One end of the two second channels 611 is respectively formed with a fourth interface 613 at the two ends of the upper side of the second housing 610, and the other end of the two second channels 611 is respectively formed with a fifth interface 614 near the middle position at the rear side of the second housing 610. There are two fourth fans 620, which are respectively arranged on the fifth interface 614, and can drive the air at the rear side of the second housing 610 to pass through the fifth interface 614 into the second channel 611. The second damper blade 640 is disposed at the outer side of the fifth interface 614, and is in transmission connection with the electric actuator, and can rotate under the drive of the electric actuator, so that the second damper blade 640 rotates to the third position C or the fourth position D, thereby opening / closing the fifth interface 614. The third channel 612 is provided with a sixth interface 615 at the left and right ends of the second housing 610, and a seventh interface 616 is provided at the bottom middle position of the second housing 610.

[0095] like Fig.19 As shown, the second channel 611 and the third channel 612 have a cross structure near the left and right ends in the second housing 610. Specifically, two third heat exchangers 630 are provided, which are respectively located near the left and right ends in the second housing 610. The second channel 611 and the third channel 612 are respectively connected to the third heat exchanger 630 at the cross position, so that the third heat exchanger 630 is connected in series to the second channel 611 and the third channel 612, so that the air in the second channel 611 and the air in the third channel 612 can exchange heat when passing through the third heat exchanger 630.

[0096] In summary, when the user needs to add a fresh air function and needs to recover the heat in the indoor air discharged to the outside, the sealed module 400 in Example 1 or the first fresh air module 500 in Example 2 can be extracted from the third installation space 130, and then the second fresh air module 600 in Example 3 can be inserted into the third installation space 130 from the installation port 133, so that the sixth interface 615 is connected to the third air inlet 131, the fourth interface 613 is connected to the first connecting port 113, the seventh interface 616 is connected to the second connecting port 123, and the fourth fan 620 is oriented toward the fourth air inlet 132. Thus, after the air conditioner 10 is turned on, it not only has the same function as the air conditioner 10 in Example 2, that is, the indoor air can be driven by the first fan 210 to enter the first installation space 110 from the first air inlet 111, filtered by the air filter 230, and then heat exchanged with the first heat exchanger 220, and finally heated by the electric heater 240 and discharged to the room from the first air outlet 112. After the third fan 520 drives the outdoor air to enter the third installation space 130 through the fourth air inlet 132, it enters the first installation space 110 through the first connecting port 113, is filtered by the air filter 230, and then undergoes heat exchange with the first heat exchanger 220, and finally is heated by the electric heater 240 and discharged to the room through the first air outlet 112, thereby providing fresh air for the room. After the indoor air enters the third installation space 130 through the third air inlet 131, it enters the second installation space 120 through the second connecting port 123, passes through the second heat exchanger 320 under the drive of the second fan 310, undergoes heat exchange, and is discharged to the outdoors through the second air outlet 122, thereby completing the replacement of the indoor air. At the same time, the indoor exhausted gas can undergo heat exchange with the second heat exchanger 320, thereby improving the energy efficiency of the whole machine.

[0097] At the same time, the air conditioner 10 in Example 3 can also obtain the function of heat recovery through the second fresh air module 600. Specifically, the second air valve blade 640 is controlled to rotate by the electric actuator, so that the fifth interface 614 is opened. As a result, the outdoor air can enter the third installation space 130 through the fourth air inlet 132 and enter the second channel 611 under the drive of the fourth fan 620, and pass through the second channel 611, the third heat exchanger 630, the fourth interface 613, and the first connecting port 113 to enter the first installation space 110, and pass through the air filter 230 and the first heat exchanger 220 under the drive of the first fan 210, and then be discharged into the room through the first air outlet 112, thereby providing fresh air for the room. In addition, the indoor air can also enter the second installation space 120 through the third air inlet 131, the sixth interface 615, the third channel 612, the seventh interface 616, and the second connecting port 123, and pass through the second heat exchanger 320 under the drive of the second fan 310 and then be discharged to the outside through the second air outlet 122, thereby discharging the old indoor air to the outside. The outdoor air in the second channel 611 and the indoor air in the third channel 612 can achieve heat exchange in the third heat exchanger 630, so that when the outdoor air enters the room, it can exchange heat with the outdoor air discharged from the room, thereby recovering the heat. In this way, the heat loss can be reduced and the energy consumption of the air conditioner 10 can be reduced.
