Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
In describing embodiments of the present application, it should be understood that the terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or number of features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of the present application, the meaning of "plurality" is two or more, unless explicitly defined otherwise.
The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for purposes of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known processes have not been described in detail in order to avoid unnecessarily obscuring the description of the embodiments of the application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
The embodiment of the application provides a display panel of an air conditioner and the air conditioner. The air conditioner may be a single operation mode, or may also be a device cluster operation mode, for example, the air conditioner may be a multi-connected air conditioner.
In an embodiment of the present application, a display panel of an air conditioner includes: the display panel comprises a display panel power supply, a voltage conversion module and a wireless signal module; the display panel power supply is electrically connected with the voltage conversion module and the wireless signal module in sequence.
The display panel refers to a display panel circuit in an air conditioner, and the air conditioner generally comprises two circuit boards: the display panel circuit and the main control circuit comprise a main control chip, a memory chip, a power chip and other components of the air conditioner. The display panel is usually a PCB board with a nixie tube, and a display screen for displaying the current working state, temperature, on-off state and other parameters of the air conditioner is arranged on the display panel.
Referring to fig. 1, fig. 1 shows a display panel 100 according to an embodiment of the present application, a display panel power supply 101, a voltage conversion module 102, and a wireless signal module 103 are disposed on the display panel 100, and the display panel power supply 101, the voltage conversion module 102, and the wireless signal module 103 are electrically connected in sequence.
The display panel power supply 101 is a power supply for supplying power to the display panel, and may be an independent small power supply, such as a power supply module with a battery, or may be a sub-power supply separated from the power supply of the main control circuit.
The voltage conversion module 102 is used for converting an electrical signal provided by the display panel power supply 101 into a power supply signal of the wireless signal module 103. In the air conditioner, the voltage provided by the panel power supply 101 is usually 5V, and the operating voltage of the wireless signal module 103 is 3.3V, so if the direct display panel power supply 101 is electrically connected with the wireless signal module 103, the power supply voltage of the wireless signal module 103 is too high, and the wireless signal module 103 is burned. Therefore, in order to protect the wireless signal module 103, the voltage conversion module 102 is disposed between the wireless signal module 103 and the display panel power supply 101, so as to convert 5V into 3.3V.
The wireless signal module 103 is a module for receiving and processing wireless signals, for example, the wireless signal module 103 may be a Wi-Fi module.
In the embodiment of the application, the wireless signal module 103 is powered by the display panel power supply 101, so that a power supply circuit is not required to be arranged on the main control panel for the wireless signal module 103 independently, and the circuit for pulling out the main control panel is reduced. Maintenance personnel or users can not be bothered by complicated connection lines when maintaining and replacing the main control board or the wireless signal module, and the operation is simpler. In addition, when maintenance personnel or users maintain and replace the wireless signal module 103, the wireless signal module can also be directly operated on the display panel 100 without being operated on the main control panel, so that the possibility of damaging the main control panel is reduced.
Further, if the wireless signal module 103 is powered by other power sources in the air conditioner, on the one hand, the voltage difference is large, the voltage conversion is inconvenient, and on the other hand, when the load of the wireless signal module 103 is excessive, if the power source is a voltage for powering key components such as a fan and a compressor, the normal operation of the air conditioner may be adversely affected, otherwise, even if the display panel power source 101 is damaged, the air conditioner can still keep refrigeration/heating, so that the adverse effect can be reduced to the minimum.
In addition, when the wireless signal module 103 is mounted on the display panel 100, the wireless signal module 103 does not occupy another PCB, so that the number of PCBs inside the air conditioner can be reduced, and the manufacturing cost of the air conditioner can be further reduced.
In some embodiments, the voltage provided by the power supply of the display panel can be converted into the working voltage of the wireless signal module through the voltage conversion module. The voltage conversion module comprises a voltage conversion chip, a power supply branch, an absorption branch and a filtering branch; the output end of the voltage conversion chip is electrically connected with the power supply signal input end of the voltage conversion chip through the power supply branch, and the electric signal after voltage conversion flows into the power supply port of the wireless signal module along the power supply branch; the absorption branch circuit and the filtering branch circuit are respectively connected with the wireless signal module in parallel, and before the electric signal flows into the power supply port, the electric connection nodes of the absorption branch circuit and the power supply branch circuit and the electric connection nodes of the filtering branch circuit and the power supply branch circuit are sequentially shunted.
Referring to fig. 2, the display panel 200 in fig. 2 includes a display panel power supply 201, a voltage conversion chip 2021, a first filter capacitor C1, a first electrolytic capacitor E1, a power supply branch 2022, an absorption branch 2023, a first grounding resistor R1, a filter branch 2024 and a wireless signal module 203. The first filter capacitor C1 and the first electrolytic capacitor E1 are used for decoupling signals, after the display panel power supply 201 sends out an electrical signal, the electrical signal flows into the power signal input end of the voltage conversion chip 2021, after the voltage of the electrical signal is converted into the working voltage of the wireless signal module 203 in the voltage conversion chip 2021, the converted power signal flows out from the output end of the voltage conversion chip 2021 and flows into the power supply port 2031 of the wireless signal module 203 along the power supply branch 2022. Before flowing into the wireless signal module 203, the electrical signal passes through the absorption branch 2023 and the filtering branch 2024, and the absorption branch functions to absorb the voltage spike generated when the display panel power supply 201 is turned on and off, so as to prevent the device from being damaged and the voltage from breakdown. Referring to fig. 3, fig. 3 adds an inductance L1 for shaping to fig. 2, when the panel power 201 is switched from an on state to an off state, although the panel power 201 does not emit an electrical signal any more, L1 is used as an element capable of storing energy, and freewheels, so that a voltage spike is generated, and when the electrical signal passes through the absorption branch 2023, a part of the electrical quantity in the electrical signal is shunted into the absorption branch 2023, so that the absorption branch 2023 can protect the wireless signal module 203 from being damaged.
After passing through the absorption branch 2023, the electrical signal also flows through the filtering branch 2024, where the filtering branch 2024 functions to filter the electrical signal, for example, the filtering circuit may be configured to filter out signals in a high frequency band, and when the electrical signal transmitted in the power supply branch 2022 flows through the filtering branch 2024, the high frequency band signal therein flows into the filtering branch 2024, so that the electrical signal flowing into the wireless signal module 203 does not include the high frequency band signal. Specifically, the filtering branch 2024 may be formed by a capacitor, for example, the filtering branch 2024 may be two capacitors connected in parallel, and one of the capacitors may be an electrolytic capacitor.
It should be noted that the voltage conversion chip 2021 may determine the voltage according to the operating voltage of the wireless signal module 203 and the voltage of the electric signal provided by the panel power supply 201. For example, when the voltage of the electric signal supplied from the panel power supply 201 is 5V and the operating voltage of the wireless signal module 203 is 3.3V, the voltage conversion chip 2021 should select a chip capable of converting the electric signal of 5V into the electric signal of 3.3V.
In some embodiments, the absorption branch may be formed by connecting an absorption capacitor and an absorption resistor. Referring to fig. 4, the display panel 300 in fig. 4 includes a display panel power supply 301, a wireless signal module 303, a shaping inductor L2, a second filter capacitor C2, a second electrolytic capacitor L2 and a second grounding resistor R2, where after an electric signal sent by the display panel power supply 301 enters a power signal input end of a voltage conversion chip 3021, the electric signal is converted into an electric signal whose voltage can be used by the wireless signal module 303, and flows out from an output end, and flows into a power supply port 3021 of the wireless signal module 303 along a power supply branch 3022 after being shaped by the inductor L2, and when the shaped electric signal flows through an absorption branch formed by parallel connection of an absorption capacitor 30231 and an absorption resistor 30232, the absorption branch can absorb a voltage spike in the shaped electric signal to protect the wireless signal module 303. When the electrical signal after the voltage spike is removed flows through the filtering branch 3024, the ac component therein flows into the filtering branch 3024 to remove the ac component in the electrical signal. The second filter capacitor C2 and the second electrolytic capacitor E2 function to decouple signals.
In some embodiments, the input port and the output port of the wireless signal module may be connected to the noise filtering module, so as to avoid the noise signal generated spontaneously in the circuit or the external noise signal entering the wireless signal module when there is no wireless signal. The wireless signal module comprises a signal receiving module, a first noise filtering module, a second noise filtering module, a signal transmission module and a wireless signal processing chip, wherein the signal transmission module is used for transmitting signals to a control chip of the air conditioner;
The signal receiving module, the first noise filtering module and the signal input port of the wireless signal processing chip are electrically connected in sequence, the input end of the second noise filtering module is electrically connected with the signal output port of the wireless signal processing chip, and the output end of the second noise filtering module is electrically connected with the signal transmission module.
Referring to fig. 5, the display panel 400 in fig. 5 includes a signal receiving module 401, a first noise filtering module 402, a wireless signal processing chip 403, a second noise filtering module 404, and a signal transmitting module 405, which are sequentially connected. The signal receiving module 401 is used for sensing and receiving wireless signals, that is, the signal receiving module 401 is used for sensing and receiving electromagnetic waves containing information and converting the electromagnetic waves into electric signals. For example, the signal receiving module 401 may be configured to receive Wi-Fi signals. The converted electric signal flows into the signal input port 4031 of the wireless signal processing chip 403 through the first noise filtering module 402, and it should be noted that the first noise filtering module is turned on only when there is a wireless signal, and if there is no wireless signal, the first noise filtering module is turned off to prevent the noise signal generated spontaneously in the circuit or the external noise signal from entering the wireless signal module. Illustratively, the first noise filtering module may be turned on and off according to a change in the level of the received signal, and the first noise filtering module 402 is turned on when the signal receiving module 401 receives the wireless signal and converts it into an electrical signal of a high level to be input to the first noise filtering module 402. When the signal receiving module 401 does not receive the wireless signal, i.e., the low level spontaneous noise signal, or the external noise signal flows into the first noise filtering module 402, the first noise filtering module 402 is turned off, and the same applies to the second noise filtering module 404.
The electrical signal processed by the wireless signal module 403 is transmitted to a control chip 406 located on the main control board through a signal transmission module 405. In other embodiments, the signal transmission module 405 may not be disposed on the display panel 400.
In some embodiments, the first noise filtering module may be constituted by a triode. Referring to fig. 6, fig. 6 illustrates a specific structure of the first noise filtering module 402 on the basis of fig. 5. Specifically, the signal receiving module 401 is electrically connected to an emitter of the first triode Q1, a base and a collector of the first triode Q1 are respectively connected to an output end of the voltage converting module 407 through a first buffer resistor R3 and a second buffer resistor R4, and the signal input port 4031 is electrically connected to a collector of the first triode Q1. When the signal receiving module 401 receives a wireless signal, the emitter of Q1 is at a high level, so Q1 is turned on, and an electrical signal generated by the signal receiving module 401 flows into the signal input port 4031 through the emitter of Q1.
In some embodiments, the second noise filtering module may also be constituted by a triode. Referring to fig. 7, fig. 7 illustrates a specific structure of the second noise filtering module 404 on the basis of fig. 5. Specifically, the signal output port 4032 of the wireless signal processing chip 403 is electrically connected to the emitter of the second triode Q2, the base and collector of the second triode Q2 are respectively connected to the output end of the voltage conversion module 407 through the third buffer resistor R5 and the fourth buffer resistor R6, and the collector of the second triode Q2 is used as the output end of the second noise filtering module and is connected to the input end of the signal transmission module 405. When the electric signal is processed in the wireless signal processing chip 403 and transmitted from the signal output port 4032 to the emitter of the second transistor Q2, the emitter of the second transistor Q2 is at a high level, so that the electric signal can be transmitted from the emitter to the signal transmission module 405.
The emitter of the second transistor Q2 may be further connected to a filter capacitor C3 when grounded, and the filter capacitor C3 may guide the ac component of the electrical signal to ground to remove the ac component.
In some embodiments, the wireless signal module on the display panel may be further connected to a display screen, where the intensity of the wireless signal received by the wireless signal module is displayed for the user to determine whether the wireless signal module works normally or whether the emission source of the wireless signal is normal. At this time, the display panel further comprises a display screen, and the wireless signal module is electrically connected with the display screen.
The wireless signal module comprises a component for detecting the signal intensity of the wireless signal so as to obtain the signal intensity of the wireless signal. After the signal intensity is obtained, the wireless signal module sends the signal intensity to the display screen, and the display screen can display corresponding signal intensity identifiers according to the signal intensity. For example, a plurality of signal strength ranges may be preset, each signal strength range corresponds to a signal strength identifier, when the signal strength is received, the display screen judges the target signal strength range in which the signal strength falls, and then displays the signal strength identifier corresponding to the target signal strength range. After the user sees the signal intensity mark from the display screen, the user can intuitively judge the level of the signal intensity according to the signal intensity mark.
The embodiment of the application does not limit the types of the signal intensity marks, and the signal intensity marks corresponding to different signal intensity ranges can be different in shape or different in color, so long as a user can intuitively judge the level of the signal intensity.
In some embodiments, the air conditioner may determine whether the wireless signal module fails according to the working condition of the display screen and the output condition of the voltage conversion module. At this time, the display panel further comprises an illumination detection unit and an alarm unit, wherein the alarm unit is respectively connected with the output ends of the illumination detection unit and the voltage conversion module.
The illumination detection unit is used for detecting illumination intensity of light emitted by the display screen; the embodiment of the application does not limit the setting position of the illumination detection unit, and the illumination detection unit can be arranged at any position on the display panel, for example, the illumination detection unit can be arranged around the display screen so as to detect the brightness of the display screen. The illumination detection unit may be a light-sensitive resistor or the like for detecting illumination, which is not limited by the embodiment of the present application.
The alarm unit is used for judging whether the display panel breaks down or not according to signals sent by the illumination detection unit and the voltage conversion module. For example, the illumination detection unit may include a photoresistor and an external power source, where the external power source is connected to the alarm unit through the photoresistor, and the alarm unit is configured to alarm when the value of the current flowing into the alarm unit is smaller than a preset current threshold. If the display screen normally emits light, the resistance value of the photoresistor can be suddenly reduced when the display screen irradiates the photoresistor, so that an electric signal input by an external power supply flows into the alarm unit, and if the voltage conversion module also normally works at the moment, both the electric signal output by the voltage conversion module and the electric signal input by the external power supply flow into the alarm unit, so that the current value flowing into the alarm unit can be larger than the current value flowing into the alarm unit when one of the voltage conversion module and the display screen does not normally work, the alarm unit can not alarm, and when one of the voltage conversion module and the display screen does not normally work, the current value flowing into the alarm unit is smaller, and the alarm unit alarms.
In order to ensure that the illumination detection unit does not take the ambient light as the light emitted by the display screen, a time detection function can be added in the logic of the air conditioner at the same time. Specifically, when the air conditioner detects through the illumination detection unit, the current time is detected first, then the corresponding current threshold value is determined according to the current time, and since the brightness of the natural light at night is lower than the brightness of the natural light at daytime, the resistance value of the photoresistor at daytime can be lower than the resistance value of the photoresistor at night, and therefore the current threshold value corresponding to night can be lower than the current threshold value corresponding to daytime.
