[0076] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0077] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0078] Heating, ventilation, and air conditioning (HVAC) systems are used to regulate the indoor environment, including functions such as heating, ventilation, and air conditioning. Their main purpose is to provide users with a comfortable and healthy indoor environment by controlling parameters such as temperature, humidity, and airflow. Common HVAC equipment includes air conditioners, radiators, and ventilation systems. These devices are widely used in residential, commercial buildings, and industrial settings.

[0079] The HVAC equipment includes an indoor unit and an outdoor unit 2, which are connected to the indoor unit through pipes. Taking the HVAC equipment as an air conditioning system as an example, the air conditioning system can be a multi-split system for buildings, which is equivalent to one or more outdoor units connected in parallel to multiple indoor units, forming a refrigerant circuit so that the refrigerant can circulate. Figure 1 The diagram shows the outdoor unit 2 of the air conditioning system. The outdoor unit 2 has a casing 3, inside which are housed a compressor, a switching valve, an outdoor heat exchanger, an outdoor expansion valve, and an oil separator. These components are connected by refrigerant piping. The switching valve is a valve used to control the flow direction of fluids (such as refrigerant or air). It switches the flow direction by changing the position of the valve core, thereby switching between different operating modes. Specifically, the switching valve can be a four-way valve, which switches between cooling and heating modes by changing the flow direction of the refrigerant.

[0080] The housing 3 is the external structure of the HVAC equipment, serving to protect internal components, provide a mounting base, and optimize airflow. The housing 3 can be made of metal or high-strength plastic, possessing good mechanical strength and corrosion resistance. The housing 3 can be rectangular and placed on the roof or ground. The housing 3 isolates internal live components from the outside environment, preventing direct contact by users and thus reducing the occurrence of safety accidents such as electric shock.

[0081] The outdoor unit 2 also includes a communication module 1, which communicates with the electronic control module of the outdoor unit 2 to reflect the operating status and fault information of the outdoor unit 2, such as temperature, power consumption, and fault information. The communication module 1 enables the rapid acquisition of operating status and fault information of the outdoor unit 2 during maintenance and inspection, thereby improving maintenance and inspection efficiency.

[0082] The communication module 1 is installed on the housing 3 and the interaction module 40 of the communication module 1 is displayed on the outside of the housing 3. The interaction module 40 can reflect the operating status information and fault information of the outdoor unit 2. In this way, the operator can quickly access the interaction module 40 of the communication module 1 to obtain the operating status information and fault information of the outdoor unit 2 without opening the outdoor unit 2, which greatly improves the efficiency of maintenance and inspection.

[0083] Communication module 1 can also enable linkage between the indoor unit and outdoor unit 2. Specifically, the HVAC equipment includes an outdoor unit communication module (i.e., communication module 1) installed on outdoor unit 2 and an indoor unit communication module installed on the indoor unit. The outdoor unit communication module is used to receive standby commands sent by the indoor unit communication module. The indoor unit communication module communicates with the outdoor unit communication module. Both the outdoor unit communication module and the indoor unit communication module can be 4G modules, 5G modules, Bluetooth modules, or Wi-Fi modules. The outdoor unit communication module receives relevant commands (power on, standby, or power off, etc.) from the indoor unit communication module, generates corresponding instructions based on the standby command, and then sends the instructions to the controller on outdoor unit 2. Outdoor unit 2 acts according to the relevant instructions to realize the power on, standby, or power off of outdoor unit 2, thereby executing the corresponding functions of the HVAC equipment.

[0084] In some embodiments, the housing 3 includes an assembly portion 4, and the communication module 1 can be installed on the assembly portion 4 with its interaction module 40 exposed through the assembly portion 4; this is not limited. The assembly portion 4 can be a grille; this is not limited.

[0085] In some embodiments, the mounting part 4 is disposed on the user-accessible side of the housing 3. Typically, the housing 3 has a top, a bottom, and a side. The top of the housing 3 protrudes from the outside of the housing 3, and the non-wall-facing side of the housing 3 also protrudes from the outside of the housing 3. The user-accessible side of the housing 3 can be the user-side surface of the housing 3, that is, when the outdoor unit 2 is used in a conventional installation posture, the plane containing the user-accessible side of the housing 3 faces the user. For the purposes of this application, the user-accessible side of the housing 3 is defined as the side of the housing 3, for example, the side of the housing 3 facing away from the wall. The user-accessible side of the housing 3 is the front of the housing 3. When the user stands in front of the outdoor unit 2, the mounting part 4 faces the user, thereby allowing the user to easily and unobstructedly access the mounting part 4. The user can directly operate and maintain the communication module 1, improving the convenience and efficiency of the inspection and maintenance of the communication module 1. For descriptive purposes, the user-accessible side of the housing 3 is now defined as the front, and the user-accessible side facing away from the housing 3 is defined as the back.

[0086] In some embodiments, the height of the mounting part 4 relative to the bottom of the housing 3 is adapted to the height of a human shoulder. This arrangement allows the user to perform ergonomic maintenance on the communication module 1, improving user comfort. For example, the height of the mounting part 4 relative to the bottom of the housing 3 is h3, which can be between 900mm and 14220mm (corresponding to the elbow-to-shoulder operating range for an adult user standing), conforming to the male shoulder height range in the "Anthropometric Dimensions of Chinese Adults" (GB / T 10000), enabling the user to perform ergonomic maintenance on the communication module 1 in the optimal operating posture.

[0087] In some embodiments, the height of the housing 3 is h4, where 0.5 ≤ h3 / h4 ≤ 0.8, for example: h3 / h4 = 2 / 3. Typically, the overall height of the housing 3 is approximately 1.5m. This design allows the height of the mounting part 4 relative to the bottom of the housing 3 to match the height of a human shoulder, enabling the user to perform maintenance and repair of the communication module 1 in the optimal operating posture, thus improving the user's comfort when maintaining the communication module.

[0088] Next, see Figures 1 to 14 The structure of communication module 1 will be described in detail.

[0089] Communication module 1 can be roughly rectangular in shape, having length, width, and thickness directions. Combined with... Figure 1 The width of the communication module 1 can be roughly along the height of the housing 3, its length is roughly perpendicular to the height of the housing 3, and its thickness is roughly along the thickness of the housing 3. That is, the communication module 1 is placed flat on the housing 3, so that the length of the communication module 1 is consistent with the length of the grille, and can be embedded in the grille.

[0090] See Figures 2 to 14The communication module 1 includes a housing 10, a circuit board 30, an interactive module 40, and a non-interactive module 50.

[0091] A receiving cavity 13 is formed within the housing 10. The housing 10 includes a first plate 111 and a second plate 121 opposite to each other along a first direction x. A circuit board 30 is located in the receiving cavity 13. The circuit board 30 has a first plate surface 31 facing the first plate 111 and a second plate surface 32 facing the second plate 121. An interaction module 40 is located in the receiving cavity 13 and is disposed on the first plate surface 31 for interaction on the first plate 111 side. A non-interaction module 50 is located in the receiving cavity 13 and is disposed on the second plate surface 32.

[0092] The aforementioned interactive module 40 can be used to display product operating status information and fault information. By setting it on the first board surface 31, interaction can be achieved only on the first board body 111 side, which facilitates interaction and improves maintenance and inspection efficiency. The non-interactive module 50 is set on the second board surface 32 of the circuit board 30, which can achieve the arrangement of electrical components on both sides of the circuit board 30, thereby improving the board surface utilization of the circuit board 30. Moreover, the double-sided component layout of the circuit board 30 is based on the interaction requirements, taking into account both the ease of interaction to improve maintenance and inspection efficiency and the improvement of the board surface utilization of the circuit board 30 to achieve the miniaturization effect of the communication module 1.

[0093] The interaction module 40 may include at least one of the following: display screen 41, button 42, NFC 43, and signal light 44, without limitation.

[0094] In this embodiment, the communication module 1 includes multiple interaction modules 40, each including a display screen 41, a button 42, an NFC 43, and a signal light 44. Along the length of the circuit board 30, the NFC 43 is located between the display screen 41 and the button 42, and the signal light 44 is also located between the display screen 41 and the button 42. The NFC 43 and the signal light 44 are distributed along the width of the circuit board 30, and the length and width directions of the circuit board 30 are perpendicular to the first direction x. The NFC 43 can be used to interact with mobile devices (e.g., mobile phones). Its placement between the display screen 41 and the button 42, approximately in the middle of the length of the circuit board 30, facilitates proximity and sensing by the mobile device. The length of the circuit board 30 is along the length of the communication module 1, the width of the circuit board 30 is along the width of the communication module 1, and the thickness of the circuit board 30 is along the thickness of the communication module 1.

[0095] The non-interactive module 50 may include a power supply terminal 51, which is not limited thereto.

[0096] Next, see Figures 3 to 8 The outer casing 10 is described in detail.

[0097] See Figure 3 The outer casing 10 includes a first casing 11 and a second casing 12. The first casing 11 includes a first plate 111, which forms a receiving cavity 13. The first casing 11 has an opening 14 communicating with the receiving cavity 13. The second casing 12 covers the opening 14 of the first plate 111 and is connected to the first casing 11. Thus, when assembling the communication module 1, the button cap 422, circuit board 30, etc., can be placed in the receiving cavity 13 of the first casing 11 through the opening 14 and assembled with the first casing 11, and then assembled with the second casing 12.

[0098] See Figures 4 to 6 The opening 14 is opposite to the first plate 111 along the first direction x. Thus, the button cap 422 and circuit board 30, inserted into the receiving cavity 13 through the opening 14, are more easily subjected to a pushing force along the first direction x, allowing them to be roughly assembled in place along the first direction x. For example, the pressing portion 4225 of the button cap 422, subjected to a pushing force along the first direction x, can pass through the button hole 1111 on the first plate 111. Similarly, the circuit board 30, subjected to a pushing force along the first direction x, can be positioned within the pressing stroke of the pressing portion 4225. Here, the first direction x can be the thickness direction of the communication module 1.

[0099] The first plate 111 has an outer surface 111a and an inner surface 111b opposite to each other along a first direction x, wherein the inner surface 111b participates in the construction of the inner wall surface of the receiving cavity 13, and at least a portion of the outer surface 111a is exposed.

[0100] The first plate 111 is provided with a button hole 1111 that communicates with the receiving cavity 13. At this time, the interaction module 40 includes a button 42 provided with the button hole 1111. The button 42 includes a switch 421 and a button cap 422. The button hole 1111 can be used to pass through the pressing part 4225 of the button cap 422.

[0101] The button hole 1111 penetrates the outer surface 111a and the inner surface 111b. The number of button holes 1111 can be one or more. The number of button holes 1111 corresponds to the number of pressing parts 4225 in the button cap 422, and one pressing part 4225 is provided in one button hole 1111.

[0102] A chamfer is provided between the inner surface 111b of the first plate 111 and the wall of the button hole 1111. This chamfer facilitates the assembly guidance of the pressing part 4225 of the button 422 through the button hole 1111 after the button 422 enters the receiving cavity 13 from the opening 14. The chamfer can be a right angle or a rounded corner, and there is no limitation on this.

[0103] The inner surface 111b of the first plate 111 is provided with a first overflow groove 1115, which is located around the button hole 1111. The first overflow groove 1115 can collect the glue that overflows when the first plate 111 and the button 422 are fixed by dispensing glue.

[0104] The first overflow groove 1115 and the button hole 1111 are spaced apart, so that when applying glue, the glue can be applied to the inner surface 111b and located in the area between the first overflow groove 1115 and the button hole 1111, so that the main body 4221 of the button cap 422 can be fixed to the inner surface 111b of the first plate 111 by glue.

[0105] When applying glue to the inner surface 111b, the glue is located between the first overflow groove 1115 and the button hole 1111, and is closer to the first overflow groove 1115, so that when the glue is squeezed by the button cap 422, it is easier to flow toward the first overflow groove 1115 and be collected by the first overflow groove 1115.

[0106] If there are multiple button holes 1111, the first glue overflow groove 1115 can be set on the periphery of all button holes 1111.

[0107] The first plate 111 is provided with a display hole 1112 communicating with the receiving cavity 13. The display hole 1112 can be used by the operator to view the information. At this time, the interaction module 40 includes a display screen 41 that is provided with a corresponding display hole 1112 and is displayed externally through the display hole 1112. The display hole 1112 penetrates the outer surface 111a and the inner surface 111b.

[0108] The display hole 1112 and the button hole 1111 are distributed along the second direction y, which is perpendicular to the first direction x. The second direction y can be the length direction of the communication module 1, and the third direction z can be the width direction of the communication module 1.

[0109] The inner wall of the display hole 1112 includes a stepped surface 1116 that faces away from the second plate 121. The stepped surface 1116 facilitates the installation and positioning of components such as the window plate 60.

[0110] The step surface 1116 is provided with a second glue overflow groove 1117, which can collect the glue overflowing when the first plate 111 and the window plate 60 are fixed by glue application.

[0111] The second overflow groove 1117 is set around the outer periphery of the step surface 1116. In this way, when applying glue, the glue can be applied to the area on the step surface 1116 where the second overflow groove 1117 is not set, so that the window panel 60 can be fixed to the step surface 1116 by glue.

[0112] When applying adhesive to the step surface 1116, the adhesive is positioned closer to the second overflow groove 1117, making it easier for the adhesive to flow toward the second overflow groove 1117 when squeezed by the window panel 60, and then be collected by the second overflow groove 1117.

[0113] The first plate 111 has a connecting protrusion 1113, which is located in the receiving cavity 13. The connecting protrusion 1113 can position the mounting position between the circuit board 30 and the first plate 111, for example, the circuit board 30 presses against the connecting protrusion 1113. There can be multiple connecting protrusions 1113, which is not limited.

[0114] The connecting protrusion 1113 is provided with a second connecting hole 1114 to fix the circuit board 30 to the first plate 111. If there are multiple connecting protrusions 1113, each connecting protrusion 1113 can be provided with a second connecting hole 1114.

[0115] The first plate 111 is provided with a light-transmitting hole 1118 communicating with the receiving cavity 13, and the portion of the light-transmitting hole 1118 is capable of transmitting light. The number of light-transmitting holes 1118 can be one or more, and there is no limitation on this.

[0116] In some embodiments, the light-transmitting hole 1118 penetrates both the outer surface 111a and the inner surface 111b, allowing light to pass directly through the light-transmitting hole 1118. In other embodiments, the light-transmitting hole 1118 does not penetrate the outer surface 111a, and the distance H2 between the bottom wall of the light-transmitting hole 1118 and the outer surface 111a satisfies: 0.4mm ≤ H2 ≤ 1.5mm. Designing the light-transmitting hole 1118 not to penetrate the outer surface 111a improves the appearance integrity of the first plate 111. Designing the distance between the bottom wall of the light-transmitting hole 1118 and the outer surface 111a to be greater than or equal to 0.4mm and less than or equal to 1.5mm allows the first plate 111 to be thinner at the light-transmitting hole 1118, enabling light transmission, and is easier to form and process. H2 can be 0.4mm, 0.7mm, 1.0mm, 1.2mm, 1.5mm, etc., and is not limited thereto.

[0117] The first housing 11 also includes a surrounding plate 113, which is connected to the periphery of the first plate 111 and forms a receiving cavity 13 with the first plate 111. An opening 14 is formed on the side of the surrounding plate 113 away from the first plate 111.

[0118] A step 1131 is provided on the side of the enclosure 113 away from the first plate 111. The step 1131 is used to accommodate part of the second shell 12.

[0119] A first mounting hole 1132 is provided on the step surface of step 1131. There can be multiple first mounting holes 1132, which are distributed circumferentially at intervals in the opening 14.

[0120] See Figure 3 , Figure 7 and Figure 8 The second shell 12 is generally plate-shaped, and at this time, the second shell 12 is generally composed of a second plate 121. The edge of the second plate 121 is placed within the step 1131 of the surrounding plate 113.

[0121] The edge of the second plate 121 is provided with a second mounting hole 1214. The second housing 12 and the first housing 11 can be locked and fixed by screws provided in the first mounting hole 1132 and the second mounting hole 1214.

[0122] The number of second mounting holes 1214 is equal to the number of first mounting holes 1132. Each first mounting hole 1132 and each second mounting hole 1214 is provided with a screw to improve the connection reliability between the second housing 12 and various parts of the first housing 11.

[0123] One of the second housing 12 and the first housing 11 is provided with a hook, and the other is provided with a slot. The hook is engaged in the slot. The hook and slot are designed to allow for pre-positioning of the second housing 12 and the first housing 11 during assembly, so as to facilitate the screw-locking operation. There can be multiple hooks, which are distributed circumferentially at intervals around the opening 14. The number of slots is equal to the number of hooks, and each hook is engaged in one slot.

[0124] In this embodiment of the application, the second housing 12 is provided with a slot 122, and the first housing 11 is provided with a hook 112.

[0125] A sealing structure such as a sealing ring can be provided between the second housing 12 and the first housing 11 to improve the sealing performance between the second housing 12 and the first housing 11.

[0126] The second plate 121 has a support protrusion 1211, which is located in the receiving cavity 13. The support protrusion 1211 presses against the second plate surface 32 of the circuit board 30, so that the circuit board 30 presses the main body 4221 of the button 422 located in the receiving cavity 13 against the first plate 111, preventing the circuit board 30 from shifting towards the second plate 121, thereby preventing the pressing part 4225 of the button 422 from shifting towards the second plate 121, ensuring the pressing effect of the operator on the pressing part 4225 of the button 422, so that the button 42 can be pressed and triggered.

[0127] The second plate 121 has multiple support protrusions 1211, so that multiple points of the circuit board 30 can be pressed by the support protrusions 1211, and the pressing effect is more balanced.

[0128] The plurality of support protrusions 1211 include a first support protrusion 1211a. At least a portion of the projection of the first support protrusion 1211a onto the first reference surface is located inside the projection of the button 422 onto the first reference surface, which is perpendicular to the first direction x. That is, the first support protrusion 1211a is provided corresponding to the button 422 and can directly press against the part of the circuit board 30 corresponding to the button 422, so as to better prevent the pressing part 4225 of the button 422 from shifting towards the direction closer to the second plate body 121, ensuring the pressing effect of the operator on the pressing part 4225 of the button 422, so that the button 42 can be pressed and triggered.

[0129] The second plate 121 has a plurality of spaced first support protrusions 1211a, so that multiple points of the circuit board 30 corresponding to the button 422 can be pressed by the first support protrusions 1211a, making the pressing effect of the circuit board 30 on the button 422 more balanced.

[0130] The plurality of support protrusions 1211 include a second support protrusion 1211b, at least a portion of the projection of the second support protrusion 1211b onto the first reference surface is located inside the projection of the display hole 1112 onto the first reference surface. That is, the second support protrusion 1211b is provided corresponding to the window plate 60 and can directly press against the part of the circuit board 30 corresponding to the window plate 60, so that the pressing effect of each part of the circuit board 30 is more balanced.

[0131] The second plate 121 has a plurality of spaced second support protrusions 1211b, so that multiple points of the circuit board 30 corresponding to the window plate 60 can be pressed by the second support protrusions 1211b, making the pressing effect of each part of the circuit board 3 more balanced.

[0132] The second plate 121 is provided with a cable outlet hole 1212 communicating with the receiving cavity 13. The cable outlet hole 1212 can be used for the circuit board 30 to exit. With the cable outlet hole 1212 provided on the second plate 121, when the interactive modules such as the window plate 60 provided at the display hole 1112 and the button cap 422 provided at the button hole 1111 on the first plate 111 are exposed through the casing 3 of the outdoor unit 2, the operator faces the interactive modules and the second plate 121 will be located on the back side, and the cable outlet hole 1212 and the cable exiting through the cable outlet hole 1212 will not be visible.

[0133] At least a portion of the second plate 121 can be placed inside the housing 3, so that the wires exiting through the wire outlet hole 1212 are directly located inside the housing 3, so as to make electrical connections with the electrical components inside the housing 3.

[0134] The second plate 121 has a sealing structure at the outlet hole 1212. For example, a sealing structure is formed around the outlet wire harness by a process such as potting glue. This is not limited.

[0135] The second plate 121 is provided with a vent 1213 that communicates with the receiving cavity 13.

[0136] The second plate 121 has a hook 123 on the side opposite to the first plate 111. The hook 123 can be used to install and fix the communication module 1 to the outdoor unit 2.

[0137] The outer casing 10 may also include a sliding cover (not shown in the figure), which is slidably connected to the first casing 11 to cover or open the button cap 422 at the button hole 1111. When the sliding cover covers the button cap 422, the operator cannot directly operate the button cap 422. Only when the sliding cover is open can the operator touch the button cap 422 and perform operations such as pressing the button cap 422.

[0138] To enhance safety, when the sliding cover obstructs the button 422, the sliding cover can be locked to the first housing 11 and / or the second housing 12. This sliding cover design allows for a concealed button 422, facilitating operation while preventing unauthorized access and improving product reliability. The sliding cover can be locked to the first housing 11 and / or the second housing 12 using screws or other methods; this is not limited to these methods.

[0139] Next, see Figure 3 , Figures 9 to 11 The circuit board 30 is described in detail.

[0140] The circuit board 30 is provided with a first connecting hole 35, which corresponds to the second connecting hole 1114 on the connecting protrusion 1113 on the first board body 111. The communication module 1 also includes a first locking member (not shown in the figure), which passes through the first connecting hole 35 and is connected to the second connecting hole 1114 on the connecting protrusion 1113, so that the circuit board 30 presses against the connecting protrusion 1113. That is, when assembling the circuit board 30, the circuit board 30 can be connected and fixed to the first housing 11 by the first locking member. The first locking member can be a screw, and there is no limitation thereto.

[0141] The circuit board 30 is provided with positioning holes 39, and the display screen 41 is provided with protrusions. The protrusions are inserted into the positioning holes 39 to realize the pre-positioning of the display screen 41 and the circuit board 30.

[0142] The circuit board 30 has multiple positioning holes 39, and the display screen 41 has a number of protrusions equal to the number of positioning holes 39, with each protrusion corresponding to one of the positioning holes 39. In this embodiment, the circuit board 30 has four positioning holes 39, which are respectively located at the four corners of the display screen 41.

[0143] Next, see Figures 2 to 14 The interactive module 40 and the non-interactive module 50 are described in detail.

[0144] The communication module 1 includes multiple interaction modules 40, which may include a display screen 41, buttons 42, NFC 43, and indicator lights 44.

[0145] The circuit board 30 is provided with interactive circuits that are electrically connected to the interactive module 40 and non-interactive circuits that are electrically connected to the non-interactive module 50. At least a portion of the interactive circuits are located on the second board surface 32, and the non-interactive circuits are also located on the second board surface 32. In this way, most of the circuits are located on the second board surface 32, and the circuits are mainly concentrated on the second board surface 32, which facilitates automated soldering and manufacturing, and also helps to miniaturize the equipment.

[0146] If the interaction module 40 includes a display screen 41, the circuit board 30 is provided with a display screen interaction circuit, and the display screen 41 is electrically connected to the display screen interaction circuit. In some embodiments, the display screen 41 is electrically connected to the display screen interaction circuit via a ribbon cable 45. At least a portion of the display screen interaction circuit is disposed on the second board surface 32, and the ribbon cable 45 is electrically connected to the display screen interaction circuit on the second board surface 32 side.

[0147] If the interaction module 40 includes a button 42, the circuit board 30 is provided with a button interaction circuit, and the button 42 is electrically connected to the button interaction circuit. The button interaction circuit is located on the second board surface 32.

[0148] If the interaction module 40 includes NFC 43, the circuit board 30 is provided with an NFC interaction circuit, and NFC 43 is electrically connected to the NFC interaction circuit. The NFC interaction circuit is located on the second board surface 32.

[0149] If the interaction module 40 includes a traffic light 44, the circuit board 30 is provided with a traffic light interaction circuit, and the traffic light 44 is electrically connected to the traffic light interaction circuit. The traffic light interaction circuit is located on the second board surface 32.

[0150] The display screen 41 is disposed on the first surface 31 of the circuit board 30 and is disposed corresponding to the display hole 1112. The display screen 41 can be used to display information such as the temperature and power of the outdoor unit 2.

[0151] In the above design, at least a portion of the projection of the second support protrusion 1211b onto the first reference surface is located inside the projection of the display hole 1112 onto the first reference surface, and the display screen 41 is provided corresponding to the display hole 1112. That is, the second support protrusion 1211b is provided corresponding to the display screen 41, and can directly press against the part of the circuit board 30 corresponding to the display screen 41, so that the pressing effect of each part of the circuit board 30 is more balanced.

[0152] Button 42 can be pressed by the operator to adjust the display interface of display screen 41. For example, if display screen 41 is displaying a first interface, pressing button 42 can switch display screen 41 to display a second interface. The display information of the first interface and the second interface differs, thus changing the display information of display screen 41. In this way, even if the display interface of display screen 41 is small, its display interface can be adjusted by button 42 to display more content. The small display interface of display screen 41 helps to reduce the size of communication module 1.

[0153] The display screen 41 and buttons 42 are distributed along the length of the circuit board 30, which can be roughly along the length of the communication module 1. The distribution of the display screen 41 and buttons 42 along the length of the circuit board 30 makes the layout of the circuit board 30 more regular and reasonable, which is conducive to reducing the width of the circuit board 30.

[0154] The button 42 includes a switch 421 and a button cap 422. The switch 421 is located in the receiving cavity 13 and is disposed on the first plate surface 31. The button cap 422 includes a main body 4221 and a pressing part 4225 connected to each other. The main body 4221 is located in the receiving cavity 13, and the pressing part 4225 passes through the button hole 1111.

[0155] The button 42 can contain multiple switches 421. In this case, the button cap 422 includes multiple pressing parts 4225, each corresponding to a switch 421. The first plate 111 has multiple button holes 1111, and each pressing part 4225 passes through a corresponding button hole 1111. By providing multiple switches 421, multiple pressing parts 4225, and multiple button holes 1111, different functions can be achieved by pressing different switches 421.

[0156] Switch 421 can be a tactile switch, dome switch, etc., and there is no limitation on it.

[0157] Ideally, after the button cap 422 and switch 421 are installed inside the housing 10, the second protrusion 4227 of the button cap 422 should just contact the switch 421. However, due to manufacturing tolerances and other factors, and because the pressing stroke of the switch 421 is small, the second protrusion 4227 of the button cap 422 may directly press the switch 421 closed after the button cap 422 and switch 421 are installed inside the housing 10. To avoid this, in this embodiment, ideally, after the button cap 422 and switch 421 are installed inside the housing 10, there is a gap of 0.1mm to 0.3mm between the second protrusion 4227 of the button cap 422 and the switch 421. This gap can eliminate the influence of manufacturing tolerances, so that the switch 421 will not be directly pressed closed after the button cap 422 and switch 421 are installed inside the housing 10.

[0158] The pressing part 4225 passes through the button hole 1111 and protrudes from the outer surface 111a of the first plate 111, making it easier for the operator to press.

[0159] The height H1 of the pressing part 4225 protruding from the outer surface 111a of the first plate 111 satisfies: 0.3mm ≤ H1 ≤ 3mm. By reasonably limiting the height of the pressing part 4225 protruding from the outer surface 111a, both the pressing feel and the excessive protrusion of the pressing part 4225 can be ensured, thus maintaining the aesthetics of the communication module 1. H1 can be 0.3mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc., and is not limited thereto.

[0160] The main body 4221 and the first plate 111 can be fixed together by applying glue. For example, glue can be applied to the area between the first overflow groove 1115 and the button hole 1111 on the inner surface 111b of the first plate 111, and the glue can be closer to the first overflow groove 1115, so that the glue can flow towards the first overflow groove 1115 more easily when it is squeezed by the button cap 422, and then be collected by the first overflow groove 1115.

[0161] The button cap 422 also includes a first protrusion 4226, which connects to the periphery of the main body 4221 and protrudes from the main body 4221. The first protrusion 4226 extends into the first glue overflow groove 1115. In this way, the first protrusion 4226 and the inner wall of the first glue overflow groove 1115 can be connected and fixed by the glue contained in the first glue overflow groove 1115, which can improve the connection stability between the button cap 422 and the first plate 111.

[0162] It should be noted that, in addition to the above-mentioned glue application method, the cap 422 and the first plate 111 can also be fixed by ultrasonic welding, in-mold injection molding, adhesive bonding, etc. This application embodiment does not limit this method.

[0163] The main body 4221 has a mounting cavity 4222. The mounting cavity 4222 has a first port 4223 and a second port 4224. The pressing part 4225 covers the first port 4223 and is connected to the main body 4221. The switch 421 can extend into the mounting cavity 4222 through the second port 4224.

[0164] The main body 4221 may have one or more mounting cavities 4222. The number of mounting cavities 4222 is equal to the number of pressing parts 4225. Each pressing part 4225 is disposed at a first port 4223 of the mounting cavity 4222. The first protrusion 4226 is located on the same side of the main body 4221 along the first direction x, and the first protrusion 4226 surrounds all the pressing parts 4225.

[0165] The cap 422 also includes a second protrusion 4227, which is located in the mounting cavity 4222 and protrudes from the pressing part 4225. The button 42 can be set to correspond to the second protrusion 4227 so that when the pressing part 4225 is pressed, the second protrusion 4227 can press the button 42 more easily.

[0166] The button cap 422 can be a one-piece molded part, reducing assembly processes and lowering production costs. The button cap 422 can be made of silicone to ensure a good pressing feel.

[0167] The main body 4221 may have a groove on the side away from the pressing part 4225 to weaken the connection strength between each pressing part 4225, so that each pressing part 4225 is independent when pressed.

[0168] NFC43 can be used to interact with mobile devices (e.g., mobile phones). For example, when a mobile device is near NFC43, it can sense NFC43 to display information about outdoor unit 2 (e.g., operating status information, fault information), allowing the mobile device to quickly display information about outdoor unit 2 without logging in.

[0169] The light emitted by the signal light 44 can pass through the portion of the first plate 31 corresponding to the light-transmitting hole 1118, allowing the operator to observe it. Specifically, when the signal light 44 is lit, the operator can see that the portion of the first plate 31 corresponding to the light-transmitting hole 1118 is lit; when the signal light 44 is not lit, the operator cannot see that the portion of the first plate 31 corresponding to the light-transmitting hole 1118 is lit.

[0170] The indicator light 44 is used to display the product's operating status and / or fault status. In some embodiments, the indicator light 44 can be used to reflect the presence or absence of a network signal; for example, the indicator light 44 is lit when there is a network signal and not lit when there is no network signal. In other embodiments, the indicator light 44 can be used to reflect whether the communication module 1 has successfully communicated; for example, the indicator light 44 is lit when communication is successful and not lit when communication is unsuccessful. In still other embodiments, the indicator light 44 can be used to reflect whether the entire machine is faulty; for example, the indicator light 44 is lit or flashing when there is a fault, and not lit when there is no faulty network.

[0171] There can be multiple indicator lights 44, and the number of light-transmitting holes 1118 is equal to the number of indicator lights 44. Each indicator light 44 corresponds to one light-transmitting hole 1118. If there are multiple indicator lights 44, different indicator lights 44 are used to reflect different information. For example, one indicator light 44 indicates whether a network signal is present, another indicator light 44 indicates whether communication module 1 has successfully communicated, yet another indicator light 44 indicates whether the entire machine is malfunctioning, and so on.

[0172] Since the display screen 41, button 42, NFC 43 and indicator light 44 are all located on the first surface 31 of the circuit board 30 facing the first board 111, and the display interface of the display screen 41 can be seen by the operator through the window board 60, the button 42 can be pressed and operated, the NFC 43 can be sensed by the mobile device, and the indicator light 44 can be lit and seen by the operator, that is, the display screen 41, button 42, NFC 43 and indicator light 44 can interact on the side of the first board 111 without disassembling the product and can realize installation, debugging and maintenance, thus improving product interaction and experience.

[0173] The non-interactive module 50 includes a power supply terminal 51, to which a wire harness is connected. The wire harness passes through the outlet hole 1212 of the second board 121. The interactive modules 40, such as the display screen 41, buttons 42, NFC 43, and indicator lights 44, which require interaction, are all located on the first board surface 31 of the circuit board 30 facing the first board 111. Other non-interactive modules 50, such as the power supply terminal 51, are located on the second board surface 32 of the circuit board 30 facing the second board 121. This arrangement ensures that electrical components are located on both sides of the circuit board 30, thereby improving the utilization rate of the circuit board 30, and also meets the interaction requirements.

[0174] The second plate 121 has a sealing structure around the wire harness at the power supply terminal 51 in the outlet hole 1212. For example, the sealing structure that wraps around the outlet wire harness is formed by processes such as potting, and there is no limitation on this.

[0175] The power supply terminal 51 is provided in correspondence with the wire outlet hole 1212 so that the wire harness of the power supply terminal 51 can pass through.

[0176] If the non-interactive module 50 includes a power supply terminal 51, the circuit board 30 is provided with a power supply terminal non-interactive circuit, and the power supply terminal 51 is electrically connected to the power supply terminal non-interactive circuit. The power supply terminal non-interactive circuit is located on the second board surface 32.

[0177] Next, we will provide further explanation of communication module 1.

[0178] The communication module 1 also includes a window plate 60, which is located at the display hole 1112 and has a stepped surface 1116. In this way, the information displayed on the display screen 41 corresponding to the display hole 1112 can be displayed externally through the window plate 60. Setting the window plate 60 can prevent dust, impurities, etc. from falling into the communication module 1.

[0179] The window panel 60 and the first panel 111 can be fixed together by applying adhesive. For example, the adhesive can be applied to the area on the step surface 1116 where the second overflow groove 1117 is not provided, and the adhesive can be placed closer to the second overflow groove 1117, so that when the adhesive is squeezed by the window panel 60, it is easier to flow towards the second overflow groove 1117 and be collected by the second overflow groove 1117.

[0180] It should be noted that, in addition to the above-mentioned glue application method, the window panel 60 and the first plate 111 can also be fixed by ultrasonic welding, in-mold injection molding, adhesive bonding, etc. This application embodiment does not limit this method.

[0181] The communication module 1 also includes a waterproof and breathable membrane 70, which is located in the receiving cavity 13. The waterproof and breathable membrane 70 covers the vent holes 1213 of the second plate 121 and is attached to the second plate 121. The waterproof and breathable membrane 70 can prevent the communication module 1 from expanding or deforming when the ambient temperature changes, increase the product's breathability, ensure the internal air pressure balance of the product, and the waterproof and breathable membrane 70 has a waterproof effect, which is beneficial to achieving the sealing of the communication module 1.

[0182] The communication module 1 includes an antenna 38, which is electrically connected to the circuit board 30, enabling the communication module 1 to access the Internet.

[0183] Antenna 38 and button 42 are distributed along the length of circuit board 30. Specifically, along the length of circuit board 30, antenna 38 is located on the side of button 42 away from display screen 41. Antenna 38 extends toward the second board surface 32 in a direction away from the first board surface 31. That is, antenna 38 is generally located on the side where the second board surface 32 is located, so as to save the area of ​​circuit board 30.
