Description

Technical Field

[0001] This utility model relates to the field of color screen wired controller technology, and in particular to an air conditioner with a color screen wired controller using an onboard antenna of a WiFi module. Background Technology

[0002] Currently, the standard 3.95-inch module screen used in the industry for 86-box color screen wired controllers is used. Part of the backlight support frame of the screen module is made of iron or aluminum alloy. This material will shield and interfere with the signal of the WiFi module's onboard antenna, affecting the transmission and reception of WiFi radio frequency signals. When the WiFi module's onboard antenna is close to metal, firstly, the metal material will absorb and reflect electromagnetic waves, and secondly, the metal material will affect the antenna impedance, causing frequency deviation of the antenna impedance, thereby affecting the WiFi antenna's signal reception and transmission.

[0003] To address this issue, the industry typically employs two approaches: first, external WiFi antennas are commonly used; however, this method affects the product's appearance, increases costs, and complicates production. Second, the antenna parameters of the WiFi module are readjusted. This requires different products to match a single set of parameters, leading to a diversity of WiFi module models, which is detrimental to material standardization and cost control, and also increases the difficulty of assembly management.

[0076] See Figure 1 An air conditioner executes a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle involves a series of processes, including compression, condensation, expansion, and evaporation, to cool or heat an indoor space.

[0077] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0078] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0079] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0080] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0081] When the air conditioner is in cooling mode, the compressor compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure state, which then enters the outdoor heat exchanger. After heat exchange in the outdoor heat exchanger, the refrigerant condenses and releases heat, becoming a liquid refrigerant. Subsequently, the refrigerant passes through a throttling element and enters the indoor side.

[0082] The refrigerant enters the indoor heat exchanger on the indoor side, evaporates and absorbs heat, and turns into a gaseous state. The refrigerant coming out of the indoor heat exchanger is finally drawn into the compressor and compressed, completing the refrigeration cycle.

[0083] When the air conditioner is in heating mode, the compressor compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure state before it enters the indoor heat exchanger.

[0084] After heat exchange inside the indoor heat exchanger, the refrigerant condenses and releases heat, becoming a liquid refrigerant. Then, the refrigerant is throttled by a throttling element to a low-temperature, low-pressure gas-liquid two-phase state. The two-phase refrigerant enters the outdoor heat exchanger, evaporates and absorbs heat, and becomes a gas.

[0085] The refrigerant from the outdoor heat exchanger is eventually drawn into the compressor and compressed to complete the heating cycle.

[0086] In some embodiments of this application, the wired controller is a common control component in multi-split air conditioners, central air conditioners, etc. It is generally installed on the wall and is used to control the operation / stop of the air conditioner, mode adjustment, parameter adjustment, control parameter display, operation parameter display, alarm prompts, etc.

[0087] In some embodiments of this application, see Figures 2 to 11 The wired controller 100 includes a screen module 160, which is connected to the wired control motherboard 110 in the wired controller 100.

[0088] In some embodiments of this application, the screen module 160 is a TFT color screen module, which includes a liquid crystal panel (not shown), a prism plate (not shown), a diffuser plate (not shown), a light guide plate (not shown), and a plurality of LEDs (not shown) arranged sequentially from the user side inwards. See also Figures 2 to 5 The screen module 160 needs to be supported and fixed by the backlight support frame 150.

[0089] In some embodiments of this application, the backlight support frame 150 is made of non-metallic material to avoid interference and shielding of WiFi signals by metal backlight support frames.

[0090] In some embodiments of this application, considering factors such as strength and cost, the backlight support frame 150 is made of plastic.

[0091] In some implementations of this application, see [link to relevant documentation]. Figures 4 to 6 The wired controller 100 also includes a WiFi module 120, which integrates an onboard antenna 121 and is electrically connected to the wired control motherboard 110 in the wired controller 100.

[0092] To facilitate the placement of the WiFi module 120, at least a second clearance portion 112 is formed on the inline control motherboard 110 to avoid obstructing the onboard antenna 121. The second clearance portion 112 forms a cutout area for the onboard antenna 121 to avoid blocking the WiFi signal and affecting the transmission and reception of the WiFi signal.

[0093] The WiFi module 120 integrates an onboard antenna 121 and has good WiFi signal transmission and reception. Therefore, different products can use the same WiFi module antenna parameters without adjusting the parameters according to different product types, which is beneficial for material standardization and cost control.

[0094] In some embodiments of this application, to facilitate the arrangement of the WiFi module 120, the size of the second clearance portion 112 is substantially equal to the size of the WiFi module 120 (see [reference]). Figure 7 and Figure 10 That is, the second clearance portion 112 forms the cutout area of ​​the WiFi module 120.

[0095] In some embodiments of this application, the connection pins of the WiFi module 120 are arranged in its circumference. The WiFi module 120 is located in the second clearance portion 112 and is electrically connected to the wired control motherboard 110. At this time, the bottom surface of the WiFi module 120 facing the user is flush with the bottom surface of the wired control motherboard 110 facing the user, which facilitates the installation of the wired control motherboard 110.

[0096] In some embodiments of this application, the backlight support frame 150 described above is made of plastic. Therefore, when the screen module 160 emits light, light leaks through the backlight support frame 150, resulting in uneven screen display and affecting the user's viewing experience. Therefore, see... Figure 5 Conductive cloth 130 is attached to the side of the backlight support frame 150 away from the screen module 160.

[0097] The screen assembly includes a liquid crystal panel, a prism plate, a diffuser plate, and a light guide plate arranged sequentially from the user side.

[0098] Several LED lights are arranged on one side wall of the backlight support frame 150 facing the screen assembly. The light emitted by the LED lights is emitted sequentially through the light guide plate, diffuser plate, prism plate and LCD panel.

[0099] In some embodiments of this application, see Figure 5 and Figure 6 The wired controller 100 consists of a screen module 160, a backlight support frame 150, a conductive cloth 130, and a wired control motherboard 110, arranged sequentially from the user side to the side away from the user side. In order to avoid the influence of the conductive cloth 130 on the WiFi signal, a first avoidance part 132 is formed on the conductive cloth 130 to avoid the onboard antenna 121, forming a hollow area of ​​the onboard antenna 121, so as to avoid blocking the WiFi signal path and affecting the WiFi signal transmission and reception.

[0100] See Figure 7 and Figure 9 The first avoidance part 132 and the second avoidance part 112 correspond to each other.

[0101] In some embodiments of this application, to facilitate the opening of the second clearance section 112, and also considering the arrangement of other electrical components on the wired control motherboard 110, see [reference needed]. Figure 6 The second clearance portion 112 is a notch opened at the edge of the in-line control motherboard 110. Correspondingly, in order to facilitate the opening of the first clearance portion 132, the first clearance portion 132 is also a notch opened at the edge of the conductive cloth 130 (see...). Figure 6 ).

[0102] In some embodiments of this application, in order to achieve the electrical connection between the wired control motherboard 110 and the screen module 160, and to quickly release the interference signal after the screen module 160 is interfered with, see [reference needed]. Figures 6 to 8 The wired controller 100 also includes an FPC (Flexible Printed Circuit) board 140 and an electrical connection portion 131 disposed on a conductive cloth 130.

[0103] See Figure 7The FPC board 140 connects to the terminal block 111 on the wired control main board 110, and a conductive cloth 130 is attached extending towards the side of the wired control main board 110 to electrically connect to the electrical connection part 131 (see...). Figure 6 ), and then extend the connection to screen module 160 (see Figure 8 ).

[0104] In some embodiments of this application, a first group of gold fingers (not shown), a second group of gold fingers (not shown), and a third group of gold fingers (not shown) may be provided on the FPC board 140.

[0105] The first set of gold fingers of the FPC board 140 is connected to the terminal block 111 on the wire control motherboard 110. The first set of gold fingers is connected to the second set of gold fingers. The second set of gold fingers is connected to the electrical connection part 131 and the second set of gold fingers is connected to the third set of gold fingers. The third set of gold fingers is connected to the screen module 160.

[0106] When the screen module 160 is interfered with, the interference signal can be transmitted from the screen module 160 through the third set of gold fingers of the FPC board 140 to the electrical connection part 131 and the second set of gold fingers, and then from the second set of gold fingers to the first set of gold fingers and the terminal block 111 on the wire control motherboard 110. The interference signal is released by the wire control motherboard 110, so as not to affect the normal operation of the screen module 160.

[0107] In some embodiments of this application, for ease of wiring, see [reference needed]. Figure 6 and Figure 8 The FPC board 140 includes a first bending portion 142, a second bending portion 143, and an extension portion 141 connecting the first bending portion 142 and the second bending portion 143.

[0108] As described above, the terminal block 111 is arranged on the side of the wire control main board 110 away from the conductive cloth 130. The first set of gold fingers at one end of the first bend 142 is electrically connected to the terminal block 111 and extends from the side of the conductive cloth 130 near the wire control main board 110 after bending to form the extension 141. The second bend 143 extends from the lower end of the conductive cloth 130 across the lower end of the backlight support frame 150 and is electrically connected to the screen module 160.

[0109] It should be noted that "lower end" refers to the lower part viewed from the user's side after the wired controller 100 has been installed.

[0110] In some embodiments of this application, in order to improve the ability to release interference signals, the wired controller 100 further includes at least one conductive part that is electrically connected to the interference signal release point (not shown) on the wired controller motherboard 110.

[0111] See Figure 10It shows three conductive parts 1901 / 1902 / 1903, which are electrically connected to interference signal release points (not shown) on the main control board 110. These conductive parts 1901 / 1902 / 1903 are distributed on one side of the main control board 110 facing the conductive cloth 130.

[0112] When the backlight support frame 150 and the wired control motherboard 110 are both mounted on the mounting housing, the conductive parts 1901 / 1902 / 1903 are all in electrical contact with the conductive cloth 130. Thus, when the screen module 160 is interfered with, the interference signal can be transmitted from the screen module 160 through the third set of gold fingers of the FPC board 140 to the electrical connection part 131, making the conductive cloth 130 energized. Since the conductive cloth 130 is electrically connected to the conductive parts 1901 / 1902 / 1903, the interference signal is transmitted to the interference signal release point on the wired control motherboard 110, realizing the release of the interference signal and thus not affecting the normal operation of the screen module 160.

[0113] In some embodiments of this application, the conductive parts 1901 / 1902 / 1903 may be conductive foam, which is attached to the interference signal release point of the wired control motherboard 110 by conductive adhesive.

[0114] In some embodiments of this application, for ease of mounting the backlight support bracket 150 and the wired control motherboard 110 onto the mounting housing, see [reference needed]. Figures 1 to 4 The mounting housing includes a mounting frame 170 and a bottom shell 180 mounted on the mounting frame 170.

[0115] The mounting housing forms the appearance of the wired controller 100.

[0116] See Figure 4 The backlight support frame 150, conductive cloth 130, and wired control mainboard 110 are all located within the mounting frame 170, and see [reference needed]. Figure 6 The screen module 160 is mounted on the backlight support frame 150 and located on one side of the mounting frame 170, while the bottom shell 180 is mounted on the other side of the mounting frame 170 and is used to cover the wired control motherboard 110.

[0117] In some embodiments of this application, for ease of installation of the backlight support frame 150, conductive parts 1901 / 1902 / 1903, wired control motherboard 110, and bottom shell 180, see [reference needed].
