Description

Technical Field

[0001] This utility model relates to the field of voice remote control technology, and in particular to a control circuit and remote control for automatically turning off an air conditioner. Background Technology

[0002] In the prior art, Chinese invention patent application (publication number CN116447735A) discloses an air conditioning control method and air conditioner that incorporates indoor fusion positioning technology. This method and air conditioner include an indoor unit, a remote control, and a user app. The indoor unit, remote control, and user app are connected via WIFI and / or Bluetooth. Position coordinate feedback devices are installed on the indoor unit, remote control, and user app. The indoor unit's position coordinate feedback device provides feedback on its position, the remote control's position feedback device provides feedback on its position, and the user app's position coordinate feedback device provides feedback on the user's position. The position information is fitted using WIFI and / or Bluetooth fusion positioning to locate the indoor unit, remote control, and user app in a three-dimensional spatial region. A triangular positional relationship is formed between the indoor unit, remote control, and user app. The distance between the indoor unit and remote control is Lk-y, the distance between the indoor unit and user app is Lk-U, and the distance between the remote control and user app is Ly-U. Based on the relationship between Lk-y, Lk-U, Ly-U, and relative preset values, the air conditioner performs the following operations on the indoor unit, remote control, and user app:

[0003] When a user enters the room, the remote control plays a welcome message and the air conditioner starts automatically; when the user leaves the room, the remote control plays a farewell message and the air conditioner turns off automatically; when the air conditioner remote control goes outside the indoor set range, the remote control plays a warning message.

[0004] Although existing air conditioning control technology can achieve the function of automatically turning off the air conditioner, the following technical problems exist:

[0005] 1. The operation is relatively complicated, requiring the cooperation of the indoor unit, remote control, and user APP to achieve the function of automatic air conditioner shutdown;

[0006] 2. The implementation requirements are relatively strict. Users need to carry a device with the user's APP installed in order to detect whether the user is within the usage range and to enable the air conditioner to automatically turn off.

[0007] 3. The functions are relatively limited. The voice module of the remote control can only broadcast messages and lacks the ability to control the air conditioner through user voice commands. Utility Model Content

[0008] To overcome the problems of cumbersome operation, strict requirements, and limited functionality in existing technologies, this invention proposes a control circuit and remote control for automatically shutting off an air conditioner, based on low-power radar and voice remote control technology. The low-power radar determines whether the user is within its detection range, enabling the air conditioner to automatically shut off after the user leaves the range by sending a shutdown signal.

[0009] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0010] On the one hand, this utility model proposes a control circuit for automatically turning off an air conditioner, including a USB interface module, a power supply module and a light module, characterized in that it also includes an infrared control module, a voice control module and a signal detection module;

[0011] The USB interface module is connected to the power supply module;

[0012] The power supply module is connected to the infrared control module, the voice control module, the light module, and the signal detection module;

[0013] The voice control module is connected to the infrared control module, the light module, and the signal detection module.

[0014] Preferably, an automatic shut-off control circuit for the air conditioner combines the signal detection module with the remote control to detect whether a user is within range, thereby enabling the automatic shut-off function after the user leaves.

[0015] More preferably, the signal detection module sets a detection time, and sends a shutdown signal to the voice control circuit when no user is detected within the detection range and the set time has been reached. The detection time is specifically 0 to 60 minutes.

[0016] The adjustable detection time provides users with more options, allowing them to modify the detection time according to different usage scenarios and control the air conditioner to automatically shut off after the set time is reached.

[0017] More preferably, the signal detection module specifically adopts radar detection, and the signal detection module specifically includes a radar detection sensor 2U3, a light-emitting diode LED1, a diode 2D2, a resistor 2R24, and a resistor 2R25;

[0018] The output terminal of the signal detection module is connected to diode 2D2. The output terminal is grounded through a series resistor 2R24 and a light-emitting diode LED1. A resistor 2R25 is also connected between the output terminal and the ground terminal.

[0019] By adding a signal detection module to the remote control, it is possible to effectively identify whether a user is within the operating range of the air conditioner. Specifically, after the user leaves the operating range, the radar detection sensor in the signal detection module detects the absence of a user and sends a shutdown signal to the voice control module. Upon receiving the shutdown signal, the control circuit in the voice control module sends a shutdown signal to the infrared control module. The signal receiving circuit in the infrared control module receives the shutdown signal and sends a shutdown signal to the signal transmitting circuit. The signal transmitting circuit then sends a shutdown signal to the air conditioner based on the received shutdown signal, thus achieving automatic shutdown after the user leaves. This automatic shutdown of the air conditioner using radar can solve the problem of forgetting to turn off the air conditioner after people leave in most office scenarios, effectively reducing the waste of electricity.

[0020] More preferably, the signal detection module employs a detection radar;

[0021] By employing detection radar, the power consumption of the remote control can be effectively reduced. It can automatically turn off when the user leaves while ensuring low power consumption and giving the remote control a longer battery life.

[0022] Preferably, the voice control module further includes a pickup circuit, a control circuit, and a speaker circuit;

[0023] The control circuit is connected to the pickup circuit, the speaker circuit, and the power supply module;

[0024] The voice control module can receive user voice commands through the pickup circuit. The control circuit processes the voice commands and sends the processed voice commands to the infrared control module. The infrared control module sends control commands to the air conditioner through the signal transmission circuit to achieve voice control of the air conditioner. In addition, the control circuit in the voice control module also receives a shutdown signal sent by the signal detection module to achieve automatic shutdown after the user leaves.

[0025] More preferably, the control circuit specifically uses a CI 130X chip to process the voice commands input by the pickup circuit;

[0026] By using this chip, voice control functionality can be added to the existing basic remote control function, enabling users to control the air conditioner by sending voice commands.

[0027] Preferably, the infrared control module consists of a signal receiving circuit and a signal transmitting circuit;

[0028] The signal receiving circuit is connected to the power supply module, the signal transmitting circuit, and the voice control module.

[0029] On the other hand, an air conditioner remote control that automatically shuts off includes a housing and a USB interface, with a control circuit for automatically shutting off the air conditioner installed inside the housing.

[0030] Preferably, the housing is provided with a sound pickup hole and a speaker hole;

[0031] The microphone hole on the housing allows for clearer reception of voice commands from the user to the remote control, while the speaker hole facilitates the output of announcements.

[0032] This invention proposes a control circuit and remote control for automatically shutting off an air conditioner. Specifically, it includes a USB interface module, a power supply module, a lighting module, an infrared control module, a voice control module, and a signal detection module. By combining the signal detection module with the remote control, the signal detection module detects the presence of a user within its range. If no user is detected, it sends a shutdown signal to the voice control module, achieving the function of automatically shutting off the air conditioner after the user leaves. The control circuit in the voice control module can process voice commands sent by the pickup circuit and the shutdown signal sent by the signal detection module, effectively saving costs by integrating voice and control functions into the voice control module. Furthermore, compared to existing technologies, this invention directly combines the signal detection module with the remote control, avoiding the cumbersome coordination of multiple parties and the operational barriers, and more simply and effectively achieving the function of automatically shutting off the air conditioner after the user leaves. On the other hand, by adding a voice control module, this invention allows users to control the air conditioner through voice commands, solving the problem of limited functionality compared to existing technologies that only provide announcements.

[0041] Example 1

[0042] like Figure 1 As shown, this utility model proposes a control circuit for automatically turning off an air conditioner, including a USB interface module, a power supply module, and a lighting module. Its feature is that it also includes an infrared control module, a voice control module, and a signal detection module.

[0043] The USB interface module is connected to the power supply module;

[0044] The power supply module is connected to the infrared control module, the voice control module, the light module, and the signal detection module;

[0045] The voice control module is connected to the infrared control module, the light module, and the signal detection module.

[0046] Preferably, the signal detection module specifically adopts radar detection, and the signal detection module specifically includes a radar detection sensor 2U3, a light-emitting diode LED1, a diode 2D2, a resistor 2R24, and a resistor 2R25;

[0047] The output terminal of the signal detection module is connected to diode 2D2. The output terminal is grounded through a series resistor 2R24 and a light-emitting diode LED1. A resistor 2R25 is also connected between the output terminal and the ground terminal.

[0048] By adding a signal detection module to the remote control, it is possible to effectively identify whether a user is within the operating range of the air conditioner. Specifically, after the user leaves the operating range, the radar detection sensor in the signal detection module detects the absence of a user and sends a shutdown signal to the voice control module. Upon receiving the shutdown signal, the control circuit in the voice control module sends a shutdown signal to the infrared control module. The signal receiving circuit in the infrared control module receives the shutdown signal and sends a shutdown signal to the signal transmitting circuit. The signal transmitting circuit then sends a shutdown signal to the air conditioner based on the received shutdown signal, thus achieving automatic shutdown after the user leaves. This automatic shutdown of the air conditioner using radar can solve the problem of forgetting to turn off the air conditioner after people leave in most office scenarios, effectively reducing the waste of electricity.

[0049] Furthermore, the signal detection module employs a detection radar, which consumes less than 5mW of power during operation.

[0050] This invention employs a dual power supply method, combining USB power and lithium battery power. Without connecting an external power source via the USB interface, the lithium battery serves as the remote control's power source. By utilizing a detection radar, the power consumption of the remote control in standby mode can be effectively reduced. This ensures the remote control automatically shuts off when the user leaves, while maintaining low power consumption and extending its battery life.

[0051] The signal detection module is set to detect a time interval. When no user is detected within the range and the set time has elapsed, it sends a shutdown signal to the voice control circuit. This detection time is specifically between 0 and 60 minutes. Providing an adjustable detection time offers users more options; the detection time can be modified according to different usage scenarios, controlling the air conditioner to automatically shut off after the set time. For example, the detection time can be shortened for higher energy-saving requirements, and appropriately extended for higher user experience requirements. The 0-60 minute time range provides users with ample time.

[0052] The control circuit specifically uses a CI 130X chip to process the voice commands output by the pickup circuit. Simultaneously, the control circuit receives and processes the shutdown signal sent by the signal detection module. All signal reception and processing for the entire remote control is centralized in the control circuit. The control circuit then sends the processed signal to the infrared control module, which completes the signal transmission. Specifically, the signals received and processed by the control circuit include the voice commands sent by the pickup circuit and the shutdown signal sent by the signal detection circuit. The voice control module integrates voice and control functions, improving the utilization of the internal space of the remote control while also saving costs.

[0053] The infrared control module consists of a signal receiving circuit and a signal transmitting circuit.

[0054] The signal receiving circuit is connected to the power supply module, the signal transmitting circuit, and the voice control module. In the infrared control module, the signal receiving circuit first receives the signal sent from the control circuit in the voice control module, and then sends the received signal to the signal transmitting circuit. The signal transmitting circuit then sends the signal to the air conditioner to control different functions of the air conditioner.

[0055] Example 2

[0056] A portable rechargeable smart voice remote control includes a housing (such as one made of translucent PC material) and a USB interface. The housing has a USB interface module, a power supply module connected to the USB interface module and located inside the housing, an infrared control module, a voice control module, a light module and a signal detection module connected to the power supply module, and an infrared control module, a power supply module, a light module and a signal detection module connected to the voice control module.

[0057] The housing is also equipped with a light module connected to the voice control module. The light module consists of two types of lights, specifically a main light and an alarm light. The main light can be used to quickly locate the remote control, and the flashing light helps the user remember the location of the remote control if they forget it. The main light can also be used as a night light to provide illumination at night. The alarm light can serve as a feedback signal for commands. When the user inputs a voice command into the remote control, the remote control will flash the alarm light and use a speaker to indicate to the user that the voice command has been received.

[0058] The voice control module uses a CI 130X chip, and its purpose is to add voice control functionality to the existing air conditioner control. The voice control commands are divided into controlling the night light function of the remote control itself and controlling the air conditioner.

[0059] The housing is provided with a microphone hole and a speaker hole. The microphone hole facilitates better pickup of the user's voice commands, and the speaker hole facilitates the output of broadcast audio.

[0060] It also includes a USB cover that works with the USB interface to protect the USB interface circuitry.

[0061] This utility model can control a lighting module (i.e., a night light), which can be controlled by voice to turn the night light on and off, adjust its brightness, and set a timer to turn it off; it can also control an air conditioner, which can be controlled by voice to turn the air conditioner on and off, adjust its temperature, mode, and other common operations; and it can also be used with a signal detection module to realize the automatic shut-off function of the air conditioner.

[0062] This invention can supply power to the power supply module via a 5V charging head connected to the USB interface module. In terms of operation, this invention does not require network connection or binding to an APP / mini-program or other complex operations. It only needs to use the low-power radar in the signal detection module to continuously scan the range within a set time to determine whether there is still a user within the detection range. If there is no user, it sends a shutdown signal to control the air conditioner to achieve the function of automatically turning off after the user leaves.
