Description

Technical Field

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

[0002] Integrated heat pump air conditioners are categorized as either with or without fresh air functions. Users can choose the appropriate unit based on their needs. For units with fresh air functions, the necessary equipment and structures are incorporated into the unit to provide fresh air indoors, and the unit also has built-in exhaust vents to dissipate excess indoor air. For units without fresh air functions, since fresh air is not required, the necessary equipment and structures are not required.

[0003] However, the large size and weight of integrated heat pump air conditioners make installation quite difficult. Furthermore, after installation, if users' needs change, they must replace the air conditioner with a new one that matches their needs, increasing costs. Therefore, there is an urgent need for an air conditioner that reduces installation complexity, allows users to adjust the air conditioner's structure and functionality to meet their needs, and reduces costs. Utility Model Content

[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 functions 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, for performing heat exchange with indoor air; a second heat exchanger, the second heat exchanger being installed in the second installation space, for performing heat exchange with outdoor air; an intermediate module, the intermediate module being arranged in the third installation space, detachably connected to the third installation space, and for controlling air exchange between indoor and outdoor.

[0006] With the above structure, an intermediate module is provided, which is detachably connected to the third installation space. Since the intermediate module can control the exchange of air between indoor and outdoor spaces, users can adjust the air conditioner's function according to their fresh air needs. That is, when the user's fresh air needs change, they can control whether and how the air between indoor and outdoor spaces is exchanged by replacing the intermediate module with the corresponding function, thereby changing the fresh air state and upgrading the air conditioner. This can expand the applicability of the air conditioner and reduce the user's installation and use costs.

[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 through a first connecting port, and the third installation space is connected to the second installation space through a second connecting port. The first air inlet, the first air outlet, and the third air inlet are connected to the indoor environment, and the second air inlet, the second air outlet, and the fourth air inlet are connected to the outdoor environment.

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

[0009] With the above structure, the first fan drives indoor air from the first air inlet into the first installation space, passes through the first heat exchanger, and is discharged through the first air outlet, thereby regulating the indoor air temperature. The second fan drives outdoor air from the second air inlet into the second installation space, passes through the second heat exchanger, and is discharged through the second air outlet, thereby achieving heat exchange between indoor 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 that air can be accurately supplied through the air duct.

[0012] In some embodiments, the air conditioner further includes an air filter, which is disposed in the first installation space and located between the first air inlet, the first communication 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 this structure, users can choose to install a sealed module in the third installation space to isolate indoor and outdoor air, depending on their needs. Alternatively, they can install a fresh air module in the third installation space to provide the air conditioner with a fresh air function. This increases the flexibility of the air conditioner, allowing users to flexibly adjust its functions according to their needs, thereby reducing costs.

[0016] In some embodiments, the sealing module 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 this structure, after the sealing module is installed in the third installation space, the third air inlet can be closed with the first sealing plate, thereby preventing indoor air from entering the third installation space through the third air inlet. The first or second communication port can be closed with the second sealing plate, thereby preventing communication between the first installation space and the second installation space, and further preventing communication between the indoor and outdoor spaces 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 in 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 and the first connecting port from the fourth air inlet and the second air outlet, thereby isolating the indoor and outdoor areas 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 installing a third heat exchanger in the fresh air module, indoor air can be discharged outdoors through the third air inlet, the second connecting port, the second heat exchange channel, and the second air outlet. Outdoor air can be discharged indoors through the fourth air inlet, the first heat exchange channel, the first connecting port, and the first air outlet. Thus, when the outdoor air exchanges fresh air with the indoor air, it can exchange heat in the third heat exchanger as it flows through the first and second heat exchange channels, thereby recovering heat and reducing the air conditioner's energy consumption and operating costs.

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

[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 present invention will become more readily apparent from the following description of the embodiment(s). BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure.

[0054] Below, with reference to the accompanying drawings, possible embodiments of the air conditioner 10 in the present application are exemplarily described.

[0055] like Figure 1 、 Figure 4-Figure 6 、 Figures 9-11 、 Figure 16-18 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 and is used to exchange heat with the indoor air. The second heat exchanger 320 is installed in the second installation space 120 and is used to exchange heat with the outdoor air. The intermediate module is arranged in the third installation space 130 and is detachably connected to the third installation space 130 to control the air exchange between the indoor and outdoor areas.

[0056] As described above, by providing an intermediate module, the intermediate module is detachably connected to the third installation space 130. Since the intermediate module can control the exchange of air between indoor and outdoor spaces, the user can adjust the function of the air conditioner 10 according to their needs. In other words, when the user's fresh air demand changes, the user can control whether and how the air between indoor and outdoor spaces is exchanged by replacing the intermediate module with the corresponding function, thereby changing the fresh air state and upgrading the air conditioner. This can expand the applicability of the air conditioner 10 and reduce the user's installation and use costs.

[0057] In some embodiments, as Figure 4-Figure 6 、 Figures 9-11 、 Figure 16-18As 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 through the first connecting port 113, and the third installation space 130 is connected to the second installation space 120 through the 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 environment, 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, as Figure 4 、 Figure 6 、 Figure 9 、 Figure 11 、 Figure 16 、 Figure 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 indoor air from the first air inlet 111 into the first installation space 110, through the first heat exchanger 220, and out of the first air outlet 112. The second fan 310 is installed in the second installation space 120, driving outdoor air from the second air inlet 121 into the second installation space 120, through the second heat exchanger 320, and out of the second air outlet 122. Thus, the first fan 210 drives indoor air from the first air inlet 111 into the first installation space 110, through the first heat exchanger 220, and out of the first air outlet 112, thereby regulating the indoor air temperature. The second fan 310 drives outdoor air from the second air inlet 121 into the second installation space 120, through the second heat exchanger 320, and out of the second air outlet 122, thereby achieving heat exchange between the indoor and outdoor air.

[0059] In some embodiments, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 9 、 Figure 11 、 Figure 16 、 Figure 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, as Figure 4-Figure 6 、 Figures 9-11 、 Figure 16-18As shown, the air conditioner 10 further includes an air filter 230, which is disposed in the first installation space 110, 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, as 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 air in the room 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 room 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 needs, so that the indoor air is isolated from the outdoor air. Alternatively, the fresh air module can 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 needs, thereby reducing the user's cost.

[0062] In some embodiments, as Figure 7 、 Figure 8 As shown, the sealing module 400 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 respectively. Thus, 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 or the second connecting port 123 can be closed by the second sealing plate 420, thereby preventing the first installation space 110 from communicating with the second installation space 120, and further preventing communication between the indoor and outdoor spaces through the third installation space 130.

[0063] In some embodiments, the first sealing plate 410 and the second sealing plate 420 can be two separate plates or can 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, as Figures 9-15The illustrated fresh air module includes a first damper blade 530 and a third fan 520. When the first damper blade 530 rotates to the first position A, it separates the third air inlet 131 from the first connecting port 113, connects the fourth air inlet 132 to the first connecting port 113, and connects the third air inlet 131 to the second connecting port 123. When the first damper blade 530 rotates to the second position B, it separates the third air inlet 131 and the first connecting port 113 from the fourth air inlet 132 and the second air outlet 122. When the first damper blade 530 is in the first position A, the third fan 520 drives outdoor air through the fourth air inlet 132 and the first connecting port 113 and into the first installation space 110. Thus, by rotating the first damper 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. This allows outdoor air, driven by the third fan 520, to enter the first installation space 110 through the fourth air inlet 132 and the first connecting port 113, and then enter the room. Alternatively, the third air inlet 131 can be connected to the second connecting port 123, allowing indoor air to enter the second installation space 120 through the third air inlet 131 and the second connecting port 123, and then be exhausted outdoors under the drive of the second fan 310. This allows fresh air to circulate between the outdoors and the indoors. When the fresh air function is not needed, the first damper blade 530 can be rotated to the second position B, separating the third air inlet 131 and the first connecting port 113 from the fourth air inlet 132 and the second air outlet 122, thereby isolating the indoor and outdoor areas and preventing air exchange.

[0065] In some embodiments, as Figure 16-Figure 22 As shown, the fresh air module includes a third heat exchanger 630, which has a first heat exchange channel and a second heat exchange channel. The first heat exchange channel connects the fourth air inlet 132 and the first connecting port 113, and the second heat exchange channel connects the third air inlet 131 and the second connecting port 123. Air in the first heat exchange channel can exchange heat with air in the second heat exchange channel. Thus, by including the third heat exchanger 630 in the fresh air module, indoor air can be discharged outdoors through the third air inlet 131, the second connecting port 123, the second heat exchange channel, and the second air outlet. Outdoor air can be discharged indoors through the fourth air inlet 132, the first heat exchange channel, the first connecting port 113, and the first air outlet. As a result, when the outdoor air exchanges fresh air with the indoor air, it can exchange heat in the third heat exchanger 630 while flowing through the first and second heat exchange channels, thereby recovering heat and reducing energy consumption and operating costs of the air conditioner 10.

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

[0067] In some embodiments, the first heat exchanger 220 is used to dissipate heat, i.e., to heat the air; the second heat exchanger 320 is used to absorb heat, i.e., to absorb heat from the air. Alternatively, the second heat exchanger 320 is used to dissipate heat, i.e., to heat the air; the first heat exchanger 220 is used to absorb heat, i.e., to absorb heat from the air.

[0068] The above content, in conjunction with the accompanying drawings, provides an exemplary description of possible embodiments of the air conditioner 10 in this application. Below, in conjunction with the accompanying drawings, the specific structure of the air conditioner 10 in this application is described in detail in a specific embodiment.

[0069] Example 1

[0070] Figure 1 This is a schematic diagram of the front orthographic projection structure of the air conditioner 10 in this application; Figure 2 for Figure 1 A schematic diagram of the left side orthographic projection structure of the central air conditioner 10; Figure 3 for Figure 1 A schematic diagram of the top orthographic projection structure of the air conditioner 10; Figure 4 This is a schematic diagram of the front orthographic projection structure showing the internal structure of the air conditioner 10 in Example 1; Figure 5 for Figure 4 The left side orthographic structural diagram of the air conditioner 10 showing the internal structure; Figure 6 for Figure 4 A schematic three-dimensional structure diagram of the air conditioner 10 showing the internal structure.

[0071] like Figures 1-6 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 module 400, which is used to isolate the indoor circulation module 200 from the outdoor circulation to prevent communication between the indoor and outdoor.

[0072] like Figures 1-6As shown, the housing 100 is rectangular in shape. The interior of the housing 100 is not divided into three parts along the vertical direction, forming a rectangular first installation space 110, a second installation space 120, and a third installation space 130. The first installation space 110 is located at the upper portion of the housing 100 and is used to install the indoor circulation module 200. The second installation space 120 is located at the lower portion 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 outer shell at each of the left and right ends of the first installation space 110 for communicating with the room, allowing indoor air to enter the first installation space 110 through the first air inlet 111. A first air outlet 112 is provided on the outer shell at the top center of the first installation space 110. The first air outlet 112 is connected to the indoor air duct, so that the temperature-adjusted air can be accurately delivered to the desired location through the air duct. A first communication port 113 is provided at the bottom of the first installation space 110, near each of the left and right ends. The first communication 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 center of the first installation space 110, and its outlet is connected to the first outlet 112. The first heat exchanger 220 is a dual-mode heat exchanger. To increase the indoor temperature, the first heat exchanger 220 acts as a condenser. The coolant condenses and releases heat in the first heat exchanger 220, exchanging heat with the air passing through it, thereby increasing the air temperature. To cool the indoor temperature, the first heat exchanger 220 acts as an evaporator. The coolant evaporates and absorbs heat in the first heat exchanger 220, thereby exchanging heat with the air passing through it, thereby decreasing the air temperature. Two first heat exchangers 220 are provided, symmetrically located on the left and right sides of the first fan 210. Two air filters 230 are provided, symmetrically arranged on 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 provided 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 operating, 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 filtration, and then be discharged from the first air outlet 112 after being heated by heat exchange 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, located on the left and right sides of the second air outlet 122. As a result, 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 provided at the top of the second installation space 120, near the left and right ends. 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 installed 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 of the second installation space 120, corresponding to the second air outlet 122. Two second heat exchangers 320 are provided, located between the two second air inlets 121, the second connecting port 123, and the second air outlet 122. This allows outdoor air to enter the second installation space 120 through the second air inlets 121 and the second connecting port 123, pass through the second heat exchangers 320, exchange heat with the second heat exchangers 320, and then be discharged through the second air outlet 122. The second heat exchanger 320 is a dual-mode heat exchanger. That is, when cooling the indoor temperature, the second heat exchanger 320 acts as a condenser. The coolant condenses and releases heat in the second heat exchanger 320, exchanging heat with the air passing through it, dissipating the heat into the air. When the indoor temperature needs to be raised, the second heat exchanger 320 acts as an evaporator. The coolant evaporates and absorbs heat in the second heat exchanger 320, exchanging heat with the air passing through the second heat exchanger 320, thereby absorbing heat from the air. Therefore, when the second fan 310 is operating, 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, exchange heat, and cool down before being discharged through the second air outlet 122.

[0077] like Figure 4-Figure 6 As shown, the outdoor circulation module 300 also includes components such as a compressor 330, an electrical control box 340, an inverter 350, an electronic expansion valve, and a reversing valve. The compressor 330 is electrically connected to the electrical control box 340 and the inverter 350, and can be controlled by the electrical control box 340 and the inverter 350. The compressor 330, the first heat exchanger 220, and the second heat exchanger 320 are connected by pipes, allowing coolant to circulate within the compressor 330, the first heat exchanger 220, and the second heat exchanger 320. After absorbing heat from the outdoor air, the second heat exchanger 320 releases it in the first heat exchanger 220, heating the indoor air.

[0078] like Figure 4-Figure 6As shown, a third air inlet 131 is provided on the housing 100 at each of the left and right ends of the third installation space 130. The third air inlet 131 communicates with the indoor air, allowing indoor air to 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 of the third installation space 130. The fourth air inlet 132 communicates with the outdoor air, allowing outdoor air to enter the third installation space 130 through the fourth air inlet 132. A mounting opening 133 is provided on the housing at the front of the third installation space 130, and the sealing module 400 can be installed into the third installation space 130 through the mounting opening 133.

[0079] Figure 7 for Figure 4 Schematic diagram of the orthographic projection structure of the 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. 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. There are two first sealing plates 410 and two second sealing plates 420, which are 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 has a rectangular shape as a whole. Thus, 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 communication 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, thereby preventing the first installation space 110 from communicating with the second installation space 120, and preventing communication between the indoor and outdoor areas through the third installation space 130.

[0080] In summary, the air conditioner 10 in Example 1 can be installed after the sealing module 400 is installed in the third installation space 130. Thus, when the air conditioner 10 is turned on, the first fan 210 drives indoor air into the first installation space 110 through the first air inlet 111. After being filtered by the air filter 230, the air is heat-exchanged with the first heat exchanger 220 before being discharged into the room through the first air outlet 112. If the performance of the first heat exchanger 220 fails to meet the required heating requirements, the electric heater 240 can be controlled to operate so that after the air has exchanged heat with the first heat exchanger 220, it is heated by the electric heater 240 before being discharged into the room.

[0081] The above description shows that if a user only needs to use the air conditioner 10 to adjust the indoor air temperature, the air conditioner 10 of Example 1 can be installed. However, if the user requires the air conditioner 10 to provide a fresh air function, the air conditioner 10 of Example 1 cannot meet the user's needs. The following describes the specific structure of the air conditioner 10 with a fresh air function in detail, taking Example 2 as an example.

[0082] Example 2

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

[0084] Figure 11 for Figure 9 The three-dimensional structure diagram of the air conditioner 10 shows the internal structure. Figures 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, indoor circulation module 200 and 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, thereby obtaining the following: Figures 9-11 Therefore, the housing 100, the indoor circulation module 200 and the outdoor circulation module 300 in the second embodiment will not be described in detail here.

[0085] Figure 12 for Figure 9 A schematic diagram of the front orthographic projection structure of the first fresh air module 500 showing the internal structure; Figure 13 for Figure 12 A schematic diagram of the left side orthographic projection of the first fresh air module 500 showing the internal structure; Figure 14 for Figure 12 A schematic top orthographic structural diagram showing the internal structure of the first fresh air module 500; Figure 15 for Figure 12 Schematic diagram of the three-dimensional structure of the first fresh air module 500. Figure 12-15 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 disposed within the first housing 510. The first housing 510 is a rectangular parallelepiped housing that matches the shape and size of the third installation space 130. A first interface 511 is provided at each end 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 provided at each end of the top of the first housing 510 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 port 513 is provided at the bottom of the first housing 510, near both ends, at positions corresponding to the second communication opening 123. After the first fresh air module 500 is installed in the third installation space 130, the third port 513 communicates with the second communication opening 123. A first channel 514 is formed within the first housing 510 between the second port 512 and the third port 513 at both ends. The first channel 514 extends in a left-right direction, with two first channel openings 515 formed at the left and right ends of the first channel 514 at positions corresponding to the second port 512 and the third port 513.

[0086] like Figure 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 damper blade 530 is located in the rectangular space. The first damper blade 530 is connected to the electric actuator and can rotate under the drive of the electric actuator. Specifically, when viewed from the front and back directions, it can be seen as follows Figure 12The first damper blade 530 is shown in a first position A, i.e., in a diagonal position, with one end of the first damper blade 530 connected to the connection point between the first interface 511 and the second interface 512, and the other end connected to the connection point between the first channel opening 515 and the third interface 513. This allows the second interface 512 to communicate with the first channel opening 515, the first interface 511 to communicate with the third interface 513, and the second interface 512 and the first channel opening 515 to 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 a second position B, i.e., in another diagonal position, with one end of the first damper blade 530 connected to the connection point between the second interface 512 and the first channel opening 515, and the other end connected to the connection point between 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 and are installed on the rear side wall of the first housing 510, located between the two first passage openings 515. When the third fans 520 are turned on, they can drive air from the rear side of the first housing 510 through the third fans 520 and into the first passage 514.

[0088] In summary, if the user requires the addition of a fresh air function, the sealed module 400 of Example 1 can be removed from the third installation space 130, and the first fresh air module 500 of Example 2 can be inserted into the third installation space 130 through the installation opening 133. The first interface 511 is connected to the third air inlet 131, the second interface 512 is connected to the first connecting opening 113, the third interface 513 is connected to the second connecting opening 123, and the third fan 520 is oriented toward the fourth air inlet 132. Thus, when the air conditioner 10 is turned on, it not only functions the same as the air conditioner 10 of Example 1, but also drives indoor air through the first air inlet 111 into the first installation space 110 via the first fan 210. After being filtered by the air filter 230, the air undergoes heat exchange with the first heat exchanger 220, and is finally discharged into the room through the first air outlet 112 via the electric heater 240. Simultaneously, the air conditioner 10 of Example 2 can also achieve the fresh air function through the first fresh air module 500.

[0089] Specifically, the electric actuator controls the rotation of the first damper blade 530, thereby connecting the second interface 512 with the first channel opening 515, and connecting the first interface 511 with the third interface 513. As a result, outdoor air can enter the third installation space 130 through the fourth air inlet 132, then enter the first channel 514 driven by the third fan 520, pass through the first channel opening 515, the second interface 512, and the first communication opening 113, enter the first installation space 110, and, driven by the first fan 210, pass through the air filter 230 and the first heat exchanger 220, and be discharged into the room through the first air outlet 112, thereby providing fresh air to 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 pass through the second heat exchanger 320 under the drive of the second fan 310 and be 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 undergo heat exchange with the second heat exchanger 320 to improve the energy efficiency of the entire machine.

[0090] The above content shows that if a user only requires the air conditioner 10 to provide a fresh air function, they can install the air conditioner 10 in Example 2, or replace the sealed module 400 in Example 1 with the first fresh air module 500. If a user requires heat recovery from the air discharged outdoors, the air conditioners 10 in Examples 1 and 2 cannot meet this requirement. The following describes in detail the specific structure of an air conditioner 10 with a fresh air function, using Example 3 as an example.

[0091] Example 3

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

[0093] Figure 18 for Figure 16 The three-dimensional structure diagram of the air conditioner 10 shows the internal structure. Figure 16-18As 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 shell 100, indoor circulation module 200 and 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, thereby obtaining the following. Figure 16-18 Therefore, the housing 100, the indoor circulation module 200 and the outdoor circulation module 300 in the third embodiment will not be described in detail here.

[0094] Figure 19 for Figure 16 A schematic diagram of the front orthographic projection structure of the second fresh air module 600 showing the internal structure; Figure 20 for Figure 16 The left side orthographic structural diagram of the second fresh air module 600 showing the internal structure; Figure 21 for Figure 16 A schematic top orthographic structural diagram showing the internal structure of the second fresh air module 600; Figure 22 for Figure 16 Schematic diagram of the three-dimensional structure of the second fresh air module 600. Figures 19-22As shown, the second fresh air module 600 includes a second housing 610, a fourth fan 620 disposed within the second housing 610, a third heat exchanger 630, and a second damper vane 640 disposed on the second housing 610. The second housing 610 is a rectangular parallelepiped housing that conforms to the shape and size of the third installation space 130. A second channel 611 and a third channel 612 are provided within the second housing 610, each isolated from the other. Two second channels 611 are symmetrically arranged in left and right sections within the second housing 610. Fourth ports 613 are formed at one end of each second channel 611, respectively, at either end of the upper portion of the second housing 610. A fifth port 614 is formed at the other end of each second channel 611, near the center of the rear portion of the second housing 610. Two fourth fans 620 are provided, each mounted on the fifth port 614, driving air from the rear portion of the second housing 610 through the fifth port 614 into the second channel 611. The second damper blade 640 is disposed outside the fifth port 614 and is in transmission connection with an electric actuator. Driven by the electric actuator, the second damper blade 640 can rotate to a third position C or a fourth position D, thereby opening or closing the fifth port 614. The third channel 612 is provided with a sixth port 615 at each of the left and right ends of the second housing 610, and a seventh port 616 at the bottom center of the second housing 610.

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

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

[0097] At the same time, the air conditioner 10 in Example 3 can also obtain a heat recovery function 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. In this way, the outdoor air can enter the third installation space 130 through the fourth air inlet 132 and then enter the second channel 611 under the drive of the fourth fan 620, and pass through the second channel 611 port, the third heat exchanger 630, the fourth interface 613, and the first connecting port 113 to enter the first installation space 110. After passing through the air filter 230 and the first heat exchanger 220 under the drive of the first fan 210, it is discharged into the room through the first air outlet 112, thereby providing fresh air for the room. In addition, 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. Driven by the second fan 310, it passes through the second heat exchanger 320 and is discharged outdoors through the second air outlet 122, thereby discharging the old indoor air outdoors. The outdoor air in the second channel 611 and the indoor air in the third channel 612 can exchange heat in the third heat exchanger 630. As the outdoor air enters the room, it can exchange heat with the outdoor air discharged from the room, thereby recovering heat. This can reduce heat loss and lower the energy consumption of the air conditioner 10.
