Implementation Method 1

A first embodiment of the present invention provides an air conditioning system, as shown in FIG1 and FIG2 , the air conditioning system includes an indoor unit 10 and an outdoor unit 20, wherein the indoor unit 10 is a duct type air conditioning indoor unit 10. The duct type air conditioning indoor unit 10 is provided with a wireless communication module 30, and the wireless communication module 30 is electrically connected to a circuit board (not shown) built into the duct type air conditioning indoor unit 10.

Therefore, the wireless communication module 30 can transmit the operation data of the duct type air conditioner indoor unit 10 and control the operation of the duct type air conditioner indoor unit 10 through interactive communication with the external communication terminal 40. The external communication terminal 40 can be one or more of a mobile communication device, a personal computer or a server.

Specifically as shown in Figure 1, in this embodiment, the outdoor unit 20 is electrically connected to the control unit 70, and the control unit 70 can generate control instructions for the air-conditioning system based on the operating data of the duct-type air-conditioning indoor unit 10 and the outdoor unit 20 of the air-conditioning system and the detected environmental data.

The control unit 70 is also connected to the router 60 for communication, or is integrated with the router 60, and the communication between the control unit 70 and the router 60 is an Ethernet wired connection. Of course, the communication between the control unit 70 and the router 60 can also be wirelessly connected.

The circuit board (not shown) of the duct type air conditioner indoor unit 10 is configured to have a port connected to the wireless communication module 30, and the wireless communication module 30 can be used to transmit the operating parameters or control instructions of the duct type air conditioner indoor unit 10. In this embodiment, the wireless communication module 30 can obtain the control instructions for the duct type air conditioner indoor unit 10 via the wireless communication connection with the router 60, and the duct type air conditioner indoor unit 10 controls and adjusts the operating state according to the control instructions.

In another embodiment of the present invention, the duct type air conditioner indoor unit 10 may also include a control instruction receiving unit (not shown) that is also communicatively connected to the circuit board of the duct type air conditioner indoor unit 10, for example, an infrared receiving device that is communicatively connected to the circuit board. The duct type air conditioner indoor unit 10 may send the received control instruction for setting the air conditioner operating state to the control unit 70 via the wireless communication connection between the wireless communication module 30 and the router 60. The control unit 70 summarizes the target parameters, environmental data, and operating state of the air conditioner set by the user, obtains the resolved control instruction through calculation, and feeds the resolved control instruction back to the duct type air conditioner indoor unit 10 via the wireless communication connection between the wireless communication module 30 and the router 60.

The external communication terminal 40 can be a mobile communication device or a remote personal computer or server that can establish communication with the control unit 70 through the Internet and the router 60, or it can be a mobile communication device or a remote personal computer or server that can establish communication with the control unit 70 directly via the router 60.

Therefore, the air conditioning system provided in this embodiment is provided with a duct type air conditioning indoor unit 10 equipped with a wireless communication module 30, and uses the wireless communication module 30 to realize interactive communication with the external communication terminal 40, intelligently controls the operation of the duct type air conditioning indoor unit 10 and the outdoor unit 20, and then intelligently controls and manages the air conditioning system. When the external communication terminal 40 is a mobile communication device or a remote personal computer or server, it can remotely communicate with the wireless communication module 30 through the Internet and the router 60, realize wireless networking of the duct type air conditioning indoor unit 10, and thus realize wireless networking of the air conditioning system and remote monitoring and control of the air conditioning system.

In particular, in this embodiment, the wireless communication module 30 and the external communication terminal 40 communicate with each other via Wi-Fi. Preferably, the wireless communication module 30 uses the router 60 to communicate with the external communication terminal 40. The router 60 can automatically select and set the route according to the channel conditions, and send signals in a forward and backward order along the best path. Therefore, the router 60 can make full use of the existing communication devices in the home and realize the signal transmission between the wireless communication module 30 and the external communication terminal 40, such as a mobile communication device, a personal computer or a server.

Of course, in other embodiments, the wireless communication module 30 and the external communication terminal 40 may also communicate wirelessly via other communication methods such as Bluetooth or ZigBee. Correspondingly, the wireless communication module 30 utilizes a receiving device capable of receiving Bluetooth signals or ZigBee signals to establish a communication connection with the external communication terminal 40, thereby realizing signal transmission between the wireless communication module 30 and the external communication terminal 40.

As shown in FIG. 1 , the air conditioning system further includes a remote controller 50 and a signal receiving unit (not shown in the figure) arranged on the duct type air conditioning indoor unit 10. The remote controller 50 is built with a signal sending unit (located inside the remote controller 50, not shown in the figure for simple illustration). The remote controller 50 uses the signal sending unit to send a signal, and the signal receiving unit receives the signal sent by the signal sending unit. The signal sending unit can also receive the signal sent by the signal receiving unit, thereby realizing the signal sending and receiving of the duct type air conditioning indoor unit 10. Of course, the signal receiving unit can also be arranged to be communicatively coupled with the wireless communication module 30, and the wireless communication module 30 can receive the signal transmitted by the signal receiving unit and send the signal to the signal receiving unit. In this embodiment, the position of the signal receiving unit is not limited to one. In order to improve the signal transmission efficiency between the wireless communication module 30 and the signal receiving unit, the signal receiving unit can be arranged close to the wireless communication module 30. In order to prevent the signal receiving unit from being contaminated by external dust and other debris, the signal receiving unit can be arranged inside the duct type air conditioning indoor unit 10. Of course, the signal receiving unit can be integrated into the wireless communication module 30.

The wireless communication module 30 has an antenna part 31, which can be built inside the wireless communication module 30 or arranged on the outer surface of the wireless communication module 30. The antenna part 31 can be arranged in a planar shape, a linear shape or any other suitable shape.

Specifically, as shown in Figures 2 and 3, the duct type air conditioner indoor unit 10 includes a housing 1, the outer surface of which is flat and at least partially buried in the ceiling, suspended ceiling 80 (see Figure 8) or a simple decorative plate. The suspended ceiling 80 or the simple decorative plate can be made of aluminum, steel, gypsum or any suitable material, and can be formed into a box shape, a gusset plate shape or any suitable form. In addition, the housing 1 of the duct type air conditioner indoor unit 10 also contains a heat exchanger, a fan and other components, which are not shown one by one in the figure for the sake of simplicity.

In this embodiment, the fan is a Sirocco fan, and the duct-type air-conditioning indoor unit 10 is a bottom-inlet side-outlet type duct-type air-conditioning indoor unit. In some embodiments of the invention, the duct-type air-conditioning indoor unit 10 can also be a side-inlet side-outlet type duct-type air-conditioning indoor unit. In other embodiments of the present invention, the fan can also be a cross-flow fan, and the duct-type air-conditioning indoor unit 10 is a side-inlet bottom-outlet type or a bottom-inlet bottom-outlet type duct-type air-conditioning indoor unit.

The outer shell 1 specifically includes a top 1a, a bottom 1b, a front panel 1c, a back panel 1d and two side walls 1e. When the outer shell 1 is installed and used, the top 1a is located on the side of the indoor ceiling 90, the bottom 1b is located on the side of the indoor floor, and the side walls 1e are respectively connected to the top 1a, the bottom 1b, the front panel 1c and the back panel 1d.

As shown in Fig. 2 and Fig. 3, the duct type air conditioner indoor unit 10 also has an electrical component box 2, which has built-in electrical parts such as a circuit board (the circuit board is located in the electrical component box 2, which is not shown in the figure for simple illustration). The electrical component box 2 can be arranged inside the housing 1, and preferably is arranged in close contact with the inner surface of the side wall 1e of the housing 1, or can be arranged outside the housing 1 as shown in Fig. 3, preferably parallel to the housing 1 and closely contact with the outer surface of the side wall 1e of the housing 1. Of course, the electrical component box 2 can also be partially arranged inside the housing 1, and the other part is arranged outside the housing 1.

Figure 2 is a schematic diagram of the duct-type air-conditioning indoor unit 10 in the installed state. Air outlets can be set on the bottom 1b, front panel 1c and back panel 1d of the outer shell. The front panel 1c can be set to outlet air and the back panel 1d can be set to inlet air, thereby forming a side-suction and side-blowing form. The front panel 1c can be set to outlet air and the bottom 1b can be set to inlet air, thereby forming a downward suction and side-blowing form.

FIG3 is a structure of a duct type air conditioner indoor unit 10 which is arranged upside down from FIG2. In this embodiment, the air inlet 12 is located at the bottom 1b of the housing 1, and the air outlet 13 is located on the front plate 1c, forming a downward suction and side blowing form, and the electrical component box 2 is arranged in parallel with the air inlet 12. Of course, in other embodiments of the present invention, the air inlet 12 can also be arranged on the back plate 1d, forming a side suction and side blowing form.

There is air flow at the air inlet 12 and the air outlet 13, which causes certain interference to the transmission of radio signals. The air path directly blows the wireless communication module 30, which is easy to cause the wireless communication module 30 to fail or cause the wireless communication module 30 to malfunction. Therefore, in this embodiment, the wireless communication module 30 is set near the air inlet 12 or the air outlet 13, which can ensure the strength of the wireless communication signal of the wireless communication module 30 while not being too close to the air inlet 12 or the air outlet 13, and can also prevent the wireless communication module 30 from being affected by the air flowing through, such as low-temperature or high-temperature outlet air or condensed water droplets entrained in the air, thereby reducing the interference to the transmission signal of the wireless communication module 30, and reducing the possibility of failure of the wireless communication module 30 or malfunction of the wireless communication module 30 due to contamination with condensed water droplets. In addition, the wireless communication module 30 is set close to or corresponding to the air inlet 12 or the air outlet 13, and the filter 14 or the air outlet grille 15 installed later can be disassembled for direct maintenance, which is convenient for maintenance.

In this embodiment, the wireless communication module 30 is arranged on the inner side of the housing 1 and is arranged corresponding to the air inlet 12 or the air outlet 13, thereby ensuring the flatness and aesthetics of the outer surface of the housing 1, and not making special requirements on the existing installation space, thereby avoiding affecting the normal installation of the duct-type air conditioner indoor unit 10 in a narrow installation space due to the arrangement of the wireless communication module 30. In addition, the wireless communication module 30 arranged on the inner side of the housing 1 is also protected by the housing 1, which can prevent dust and the like from adhering to and damaging the wireless communication module 30, thereby avoiding malfunction or misoperation of the wireless communication module.

At the same time, because the wireless communication module 30 is arranged corresponding to the air inlet 12 or the air outlet 13, the open space at the air inlet 12 or the air outlet 13 can be fully utilized to ensure the strength of the wireless communication signal that can be received and sent by the wireless signal module 30 arranged on the inner side of the shell 1.

The wind enters the housing 1 from the air inlet 12 and leaves from the air outlet 13. The path of the wind flowing in the housing 1 is the wind path. Preferably, the wireless communication module 30 is arranged around the air inlet 12 or the air outlet 13 in a manner deviating from the wind path directly facing the above-mentioned wind path. The wireless communication module 30 arranged in this way deviates from the air inlet 12 or the air outlet 13, that is, avoids the above-mentioned wind path, which can avoid direct blowing of cold wind or hot wind. The wireless communication module 30 is located at a position with a small temperature difference inside the housing 1, thereby reducing the condensation of air on the wireless communication module 30.

As shown in Figure 4 (part of the bottom 1b is hidden), the wireless communication module 30 is arranged on the bottom 1b and is located around the air inlet 12. The wireless communication module 30 is arranged close to the edge of the air inlet 12. The wireless communication module 30 avoids the air inlet 12 and the air outlet 13 at the same time, thereby avoiding direct blowing of cold air or hot air. The temperature difference at the wireless communication module 30 is small, which also reduces the condensation of air on the wireless communication module 30.

The duct-type air-conditioning indoor unit 10 provided in this embodiment is provided with a wireless communication module 30, which can realize interactive communication with an external communication terminal 40 via a router to transmit the operating data of the duct-type air-conditioning indoor unit 10, control the operation of the duct-type air-conditioning indoor unit 10 according to the transmitted operating data, and intelligently control the operation of the duct-type air-conditioning indoor unit 10.

Specifically, the operation data of the duct-type air conditioner indoor unit 10 is received through the external communication terminal 40, and the operation data is displayed to the user. The above-mentioned operation parameters at least include: switch status, current indoor temperature, current outdoor temperature and current operation mode, etc., and more intelligent ones also include air quality indicators such as current indoor humidity and current indoor carbon dioxide concentration. The user selects and controls according to the transmitted operation data, and uses the external communication terminal 40 to send a control instruction to the duct-type air conditioner indoor unit 10 via the Internet-router 60-wireless communication module 30. The wireless communication module 30 transmits the received control instruction to the circuit board of the duct-type air conditioner indoor unit 10. The circuit board parses the control instruction, and implements control operations on the duct-type air conditioner indoor unit 10 and the outdoor unit 20 according to the parsed control instruction.

As shown in FIG3 , the signal transmitted by the wireless communication module 30 is radiated outwardly from the antenna part 31, and the wireless signal in the direction directly facing the antenna part 31 is stronger. In this embodiment, the antenna part 31 of the wireless communication module 30 is arranged toward the air outlet 13 or the air inlet 12 in a manner corresponding to the air outlet 13 or the air inlet 12. The wireless signal transmitted by the wireless communication module 30 through the router can be smoothly radiated to the outside of the housing 1 through the air outlet 13 or the air inlet 12, and received by the external communication terminal 40; correspondingly, the wireless signal transmitted by the external communication terminal 40 can also smoothly pass through the air outlet 13 or the air inlet 12, and be captured and received by the wireless communication module 30, which is conducive to the communication connection between the external communication terminal 40 and the wireless communication module 30.

The wireless communication module 30 can be fixed to the housing 1 by screws or a snap-fit structure (not shown). In this case, the wireless communication module 30 and the housing 1 are detachably connected, which is convenient for installing, repairing or replacing the wireless communication module 30 .

Implementation Method 2

The second embodiment of the present invention provides a duct-type air-conditioning indoor unit 10. The second embodiment is a further improvement on the first embodiment. Parts not specifically described, including figure marks and text descriptions, are the same as those of the first embodiment and will not be repeated here.

The main improvement of the second embodiment over the first embodiment is that, in the second embodiment of the present invention, the wireless communication module 30 is arranged on the outer surface of the housing 1, or is arranged on the outer side of the housing 1 and does not contact the housing 1. As shown in FIG5, FIG5 is a schematic diagram of the duct type air conditioner indoor unit 10 in the installed state, and the wireless communication module 30 is arranged on the outer surface of the housing 1. Specifically, the housing 1 is arranged at the bottom 1b of the housing 1 and close to the left side, that is, the wireless communication module 30 is away from the air inlet and the air outlet at the same time. The wireless communication module 30 is arranged on the outer surface of the housing 1, and the connection between the wireless communication module 30 and the external communication terminal 40 is not easily shielded by the housing 1, which is conducive to the wireless communication module 30 and the external communication terminal 40 to achieve communication connection through the router. At the same time, the wireless communication module 30 is arranged on the outer surface of the housing 1, which is convenient for the maintenance and replacement of the wireless communication module 30.

As shown in Figure 6, the wireless communication module 30 is arranged on the bottom 1a of the shell 1, and is preferably arranged on the electrical component box 2 parallel to the air inlet 12. The wireless communication module 30 avoids the air inlet 12 and the air outlet 13 at the same time to avoid facing the air inlet 12 or the air outlet 13, thereby reducing the air flow and temperature difference at the wireless communication module 30, improving the signal transmission strength of the wireless communication module 30 and avoiding condensation of air on the wireless communication module 30.

Implementation Method 3

The third embodiment of the present invention provides a duct-type air-conditioning indoor unit 10. The third embodiment is a further improvement on the first or second embodiment. The parts not specially explained, including the figure marks and text descriptions, are the same as the first or second embodiment and will not be repeated here.

The main improvement of the third embodiment over the first or second embodiment is that in the third embodiment of the present invention, a decorative grille or decorative panel is installed corresponding to the air inlet or outlet. In conjunction with FIG. 7 , a decorative panel is provided at the air outlet 13, and an air outlet grille 15 is provided on the decorative panel. The air outlet grille 15 has an air guiding function to guide the air outlet of the duct type air conditioner indoor unit 10 to blow to a certain set angle or range, thereby improving the air flow effect in the room, promoting the uniform temperature in the room, and reaching the set temperature as soon as possible. The air outlet grille 15 can be horizontal, vertical, or filter-shaped.

The wireless communication module 30 can be arranged on the outer surface of the decorative panel as shown in FIG. 7 , and the communication of the wireless communication module 30 is not easily interfered with or affected by the air outlet grille 15. In particular, in other embodiments, if the wireless communication module 30 is arranged on the inner side of the housing 1, the antenna part 31 of the wireless communication module 30 is arranged to face the air inlet 12 in a manner corresponding to the air outlet grille 15, and the antenna part 31 of the wireless communication module 30 is not easily blocked by the air outlet grille 15, thereby reducing the interference of the air outlet grille 15 with the wireless signal transmitted or received by the wireless communication module 30.

Implementation Method 4

The fourth embodiment of the present invention provides a duct-type air-conditioning indoor unit 10. The fourth embodiment is a further improvement of the first to third embodiments. The parts not specially explained, including the figure marks and text descriptions, are the same as the first to third embodiments and will not be repeated here.

The main improvement of the fourth embodiment over the first to third embodiments is that, in the fourth embodiment of the present invention, as mentioned above, the wireless communication module 30 has a built-in antenna. In order to further enhance the signal transmission strength of the wireless communication module 30, the duct type air conditioner indoor unit 10 also includes an external antenna (not shown). The external antenna is connected to the wireless communication module 30, which is conducive to the external communication terminal 40 to communicate with the wireless communication module 30 via a router.

In particular, the external antenna is arranged toward the air inlet 12 or the air outlet 13 in a manner corresponding to the air inlet 12 or the air outlet 13. The external antenna is arranged directly opposite the air inlet 12 or the air outlet 13, which enhances the communication connection between the external communication terminal 40 and the wireless communication module 30.

In conjunction with FIG9 , a signal window 17 is provided on the housing 1, and the signal receiving/transmitting surface 31 of the wireless communication module 30 or the external antenna connected to the wireless communication module 30 is arranged corresponding to the signal window 17. More preferably, the opening position of the signal window 17 is arranged away from the air outlet 13 and the air inlet 12, and the signal window 17 is arranged on the back plate 1d and away from the air inlet 12 and the air outlet 13. In this way, the signal receiving/transmitting surface 31 of the wireless communication module 30 and the external antenna are both oriented away from the air outlet 13 and the air inlet 12.

According to the setting of this scheme, the wireless signal is transmitted through the signal window 17, which can avoid the shielding of the metal shell 1 on the wireless signal transmission. At the same time, the distance relationship between the wireless communication module 30 and the air outlet 13 and the air inlet 12 can be set with greater freedom, which is conducive to the external communication terminal 40 and the wireless communication module 30 to achieve communication connection through the router.

In particular, the signal window 17 is an opening, and the signal window 17 is an opening and is opened on the housing 1, which reduces the interference of other objects on the wireless signal transmitted through the signal window 17, and the wireless signal has less loss during the transmission process, good signal strength, and stable transmission. At this time, the signal window 17 can also play a certain role in heat dissipation, and can partially dissipate the heat generated by the operation of the electrical components inside the housing 1, thereby preventing the duct-type air conditioner indoor unit 10 from malfunctioning due to excessive temperature.

Of course, in other embodiments, in order to improve the integrity of the housing 1 and prevent dust and the like from entering the interior of the housing 1 through the signal window 17, the signal window 17 may also be made of a material such as ordinary glass or ordinary resin that has a small shielding effect on communication signals. The signal window 17 thus configured has a small shielding effect on wireless signals, reduces interference to wireless signals transmitted through the signal window 17, and has good signal strength and stable transmission.

Implementation Method 5

The fifth embodiment of the present invention provides a duct-type air-conditioning indoor unit 10. The fifth embodiment is a further improvement of the first to fourth embodiments. The parts not specially explained, including the figure marks and text descriptions, are the same as the first to fourth embodiments and will not be repeated here.

The main improvement of the fifth embodiment over the first to fourth embodiments is that in the fifth embodiment of the present invention, the wind enters the housing 1 from the air inlet 12 and leaves from the air outlet 13, and the path of the wind flowing in the housing 1 is the wind path. In conjunction with Figures 10 and 11, a partition 21 is provided inside the housing 1, and the partition 21 divides the housing 1 into two. A fixed plate 22 and a heat exchanger 23 are provided on one side of the partition 21, and a fan 24 is provided on the other side of the partition 21. In conjunction with Figure 12, the electrical component box 2 and the air inlet 12 are arranged side by side in the length direction of the air inlet 12, and the heat exchanger and the air inlet 12 are arranged side by side in the width direction of the air inlet 12. A space is formed between the electrical component box 2 and the front plate 1c, the side wall 1e, and the heat exchanger 23 to avoid the air inlet 12 and the air outlet 13, thereby avoiding the wind path. A fixed plate 22 is provided in the space tilted downward toward the front plate 1c, and the wireless communication module 30 is provided on the fixed plate 22. The wireless communication module 30 is arranged away from the air inlet 12 and the air outlet 13, which can avoid direct blowing of cold air or hot air. The wireless communication module 30 is located at a position with a smaller temperature difference inside the shell 1, thereby reducing condensation of air on the wireless communication module 30.
