The wire controller can be applied to an indoor unit of an air conditioner, and a control panel on the indoor unit is provided with a communication connection port with the wire controller.
The air conditioner referred to in the present application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state 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 heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
Referring to fig. 1, a line controller includes:
an NFC chip 200 including a Vout port 210 and a Vin port 220; the Vout port 210 is an output port of the NFC chip 200 for radio frequency field energy, and the Vin port 220 is an input port for supplying power to the NFC chip;
the Vout port 210 is connected to the Vin port 220; that is, in this embodiment, the power output from the Vout port 210 may supply power to the NFC chip 200 through the Vin port 220;
an antenna unit 100 electrically connected to the NFC chip 200; the NFC equipment is used for receiving control information, radio frequency field energy and the like sent by a mobile terminal with an NFC function;
a micro control unit 300 communicatively connected to the NFC chip 200; for transmitting control instructions and feeding back the operating state of the NFC chip 200;
wherein the Vout port 210 is electrically connected to the micro control unit 300. I.e. the micro control unit 300 can be woken up by the voltage output from the Vout port 210, so that the micro control unit 300 enters an operating state.
In some embodiments of the present invention, the NFC chip converts the received radio frequency field energy into electrical energy and outputs the electrical energy through a Vout port; the output voltage of the Vout port is VDD. When the NFC chip 200 is not powered by the power supply, the NFC chip 200 can output the voltage obtained by the antenna unit 100 through the Vout port 210.
In some embodiments of the present invention, the NFC chip 200 is further configured to store control information set by the mobile terminal. Because the Vout port 210 is connected to the Vin port 220 at the same time, the voltage output by the Vout port 210 may also supply power to the NFC chip 200 through the Vin port 220, so that the NFC chip 200 can enter a working state to receive and store control information set by the mobile terminal, and the micro control unit 300 can obtain and call the control information conveniently.
In some embodiments of the present invention, the output voltage VDD is used to wake up the micro control unit 300, that is, after the Vout port 210 of the NFC chip 200 is electrically connected to the micro control unit 300, the output voltage VDD obtained by the output voltage VDD may be used as a power supply voltage for waking up the micro control unit 300.
In some embodiments of the present invention, when the line controller enters the power saving mode, the mcu 300 enters the deep sleep mode, and the mcu 300 cannot acquire the control command and transmit the control command. Therefore, when the mobile terminal with NFC functionality and control content therein is close to the antenna unit 100 of the wire controller, the NFC chip 200 converts the received radio frequency field energy of the mobile terminal into electrical energy, and the Vout port 210 outputs the voltage VDD. As shown in fig. 1, the Vout port 210 is electrically connected to not only the Vin port 220, but also the micro control unit 300, so that the output voltage VDD can be supplied to the NFC chip 200 through the Vin port 220, so that the NFC chip 200 can store the control information set by the mobile terminal in the memory of the NFC chip 200. In addition, since the micro control unit 300 may also receive the output voltage VDD, the micro control unit 300 can be woken up and enter an operating state, communicate with the NFC chip 200 to acquire control information set by the mobile terminal, and execute the control information.
In this embodiment, the line controller can implement standby energy saving by the way that the micro control unit 300 enters deep sleep, but since the power supply always supplies power to the line controller, 0W standby cannot be implemented.
In some embodiments of the present invention, referring to fig. 2, the line controller further includes a power saving control unit 500 and a power supply 400; the power saving control unit 500 is connected to the power supply 400; the Vout port 210 is connected to the power saving control unit 500. That is, the voltage output from the Vout port 210 enables the power saving control unit 500 to continue to control the operation of the power supply 400, thereby enabling the power supply 400 to supply power to the line controller.
In some embodiments of the present invention, the power saving control unit 500 controls the power supply 400 to suppress unnecessary power consumption and reduce waste factors, and absorb the waste to convert it into useful power, so as to reduce power consumption.
In some embodiments of the present invention, and with continued reference to figure 2, the power supply 400 will disconnect power to the line controller after the line controller enters the power saving mode. Therefore, when the mobile terminal with NFC functionality and control content therein is close to the antenna unit 100 of the wire controller, the NFC chip 200 converts the received radio frequency field energy of the mobile terminal into electrical energy, and the Vout port 210 outputs the voltage VDD. Since the Vout port 210 is electrically connected to not only the Vin port 220 but also the power saving control unit 500, the output voltage VDD can be supplied to the NFC chip 200 through the Vin port 220, so that the NFC chip 200 can store the control information set by the mobile terminal in the memory of the NFC chip 200. In addition, since the power saving control unit 500 can also receive the output voltage VDD, the power saving control unit 500 can continue to control the power supply 400 to supply power to the line controller, that is, the micro control unit 300 can enter a normal operating state, communicate with the NFC chip 200 to acquire the control information set by the mobile terminal, and execute the control information.
In this embodiment, 0W standby of the line controller is achieved by disconnecting the line controller power supply. The power supply of the power saving control unit 500 is restored by the output voltage of the Vout port 210, so that the control of the power supply 400 is restored, and the wire controller operates, during which the NFC chip 200 also completes the storage of the control information in the mobile terminal.
In some embodiments of the present invention, an air conditioner includes the line controller. Specifically, a control panel is provided in the indoor unit module of the air conditioner, and the control panel is in communication connection with the micro control unit 300 of the line controller. In the process of air conditioner operation, a user can set corresponding adjusting parameters of the air conditioner through the wire controller, namely after a control command is formed on the wire controller, the micro control unit 300 sends the control command to the control panel of the indoor unit module in a wireless communication mode, and the control panel executes the control command, so that the purpose of realizing air conditioner control by using the wire controller is achieved.
Compared with the prior art, the technical scheme of the invention has the following technical effects:
according to the invention, the NFC chip is enabled to store the control information by utilizing the function of the NFC chip, and meanwhile, the output voltage of the Vout port is utilized to wake up the line controller, and the control information stored by the NFC chip can be read and executed after the line controller is woken up. Both realized the awakening of line controller under outage or the deep sleep, also accomplished control operation simultaneously, reduced the tradition and awaken the back and need wait for the step of carrying out control operation again, promoted user experience by a wide margin.
When the micro control unit 300 of the line controller is in the deep sleep mode, the Vout port 210 of the NFC chip 200 inputs the voltage obtained by the radio frequency field into the micro control unit 300 through the electrical connection, and first wakes up the micro control unit to enable the micro control unit to enter a normal working state, and when the micro control unit 300 has the capability of being in communication connection with the NFC chip 200, the control information stored in the NFC chip 200 when the micro control unit 300 is in the deep sleep mode can be processed.
When the power supply 400 powers off the line controller, the Vout port 210 of the NFC chip 200 inputs the voltage obtained from the radio frequency field into the power-saving control unit 500 through electrical connection, so as to wake up the power-saving control unit 500, and enable the power supply 400 to continue to be controlled to operate, thereby supplying power to the line controller. And then the micro control unit 300 enters a normal working state, and the capability of communication connection with the NFC chip 200 is recovered, so that the control information stored in the NFC chip 200 can be processed when the online controller is powered off.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
