Technical Field

[0001] The present invention belongs to the field of air conditioner control devices, and more specifically, it relates to an intelligent auxiliary main unit and sub-unit for air conditioner control and an air conditioner intelligent adjustment method. Background Art

[0002] An air conditioner, that is, an air regulator, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air in a building or structure.

[0003] An air conditioner generally includes a cold source / heat source device, a cold and heat medium distribution system, a terminal device, and several other auxiliary devices. It mainly includes: a refrigeration main unit (i.e., the so-called air conditioner outdoor unit), a water pump, a fan, and a pipeline system. The terminal device (i.e., the indoor air conditioner) is responsible for using the distributed cold and heat to specifically process the air state so that the air parameters of the target environment meet certain requirements.

[0004] Air conditioners are an indispensable part of people's modern life. Currently, air conditioners mainly achieve the on / off and temperature adjustment of the air conditioner through a mobile terminal (remote control or mobile phone), which is not only troublesome to operate but also has a low degree of intelligence. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an intelligent auxiliary main unit for air conditioner control and a sub-unit used in conjunction with the main unit, which have the advantages of power saving, extending the service life of the air conditioner, and high degree of intelligence.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: An air conditioner intelligent adjustment method includes a fixed main unit and a mobile sub-unit for controlling the air conditioner. When there is no human activity in the air conditioner temperature adjustment area within a certain period of time, the main unit and / or the sub-unit turn off the air conditioner; when the voltage data input to the air conditioner fluctuates by more than a specified amount, the main unit and / or the sub-unit issue an abnormal prompt; when the air conditioner runs continuously for a specified time but the temperature does not reach the preset temperature, the main unit and / or the sub-unit issue an abnormal prompt.

[0007] The advantages of this solution are at least as follows: 1. Energy conservation and environmental protection: Automatically cut off power when there is no one, reduce energy consumption, and improve the use efficiency of the air conditioner; 2. Safe and reliable: Real-time monitor voltage abnormalities and remind users to pay attention to potential safety hazards; real-time monitor the indoor temperature and remind users to pay attention to abnormal air conditioner cooling.

[0008] In addition, compared with the existing technology, this solution has the following innovative breakthroughs: Breakthrough 1: Human body sensing infrared recognition technology. This technology enables a main unit to recognize most areas. At the same time, with the cooperation of a movable sub-unit, a space recognition rate of more than 98% can be achieved, solving the problem of blind spots in induction caused by different house types in the existing technology. This means that regardless of the size of the room, this solution can accurately recognize and control the on / off state of air conditioning equipment.

[0009] Breakthrough 2: Solution to voltage problems. When 99% of people think the air conditioning cooling effect is not good, they default that the refrigerant has been consumed, and the general solution is to add refrigerant. However, in reality, many problems may lie in the voltage. This solution can monitor voltage anomalies and prompt users in a timely manner when problems are found, avoiding users' wrong cognitions caused by unstable voltage, overcoming technical biases, and avoiding blind maintenance.

[0010] An intelligent auxiliary main unit for air conditioning control, including a housing 1.

It also includes: An infrared receiving module for learning the functions of the air conditioning remote control; A human body sensing module for sensing the activities of people in the monitoring area; A wireless communication module. When it detects that there is no human activity and the time reaches the preset value, the controller automatically sends a shutdown command to the air conditioner or actively cuts off the power.

[0011] The advantages of this solution are at least as follows: The intelligent main unit of this solution and the air conditioning remote control are independent of each other. The intelligent main unit is fixed beside the air conditioner as a power strip and provides power for the air conditioner. The infrared receiving module can be used to receive the instructions sent by the air conditioning remote control to the air conditioner and learn the instructions (including but not limited to the air conditioning shutdown function). The human body sensing module can sense the activities of people in the sensing area. When there is no human activity in the sensing area for a certain period of time, the intelligent main unit can send a shutdown command to the air conditioner through the wireless communication module, which can save electricity and extend the service life of the air conditioner.

[0012] The present invention is further configured as: It further includes a voltage monitoring module and a voltage anomaly indicator lamp electrically connected to the voltage monitoring module through a controller. When the voltage data fluctuation is greater than the specified amount, the voltage anomaly indicator lamp lights up.

[0013] The advantages of this solution are at least as follows: When there are multiple air conditioners running on one line, by real-time monitoring the voltage status, the intelligent main unit can promptly give an anomaly prompt to help users understand the voltage problem and take corresponding measures to avoid being maliciously guided to add fluorine, etc.

[0014] The present invention is further configured as follows: it further includes a temperature sensing module and a temperature anomaly indicator light electrically connected to the temperature sensing module through a controller. When it is detected that the air conditioner has been running continuously for a specified time but the temperature has not reached the preset temperature, the temperature anomaly indicator light turns on.

[0015] The advantages of this solution are at least as follows: when the temperature does not drop after the air conditioner has been turned on for a certain period of time, the intelligent host can automatically detect and give a prompt through the temperature sensing module. Users can judge whether it is a device problem or insufficient refrigerant based on the prompt, so as to conduct targeted troubleshooting and solution.

[0016] The present invention is further configured as follows: a first Fresnel hemispherical lens for improving the detection and reception sensitivity is provided at the front ends of the infrared receiving module, the human body sensing module, the wireless communication module, and the temperature sensing module.

[0017] The advantages of this solution are at least as follows: the Fresnel hemispherical lens has the function of enhancing the sensitivity of the sensor (signal enhancement and amplification). Placing it at the front end (receiving and transmitting end) of each sensor can effectively improve the sensitivity of the sensor.

[0018] The present invention is further configured as follows: it further includes a voltage display module electrically connected to the voltage monitoring module through a controller.

[0019] The advantages of this solution are at least as follows: the voltage data can be displayed in real time through the voltage display module, and the input voltage of the air conditioner can be seen more intuitively, improving the emergency response speed for voltage anomalies.

[0020] The present invention is further configured as follows: it further includes a temperature display module electrically connected to the temperature sensing module through a controller.

[0021] The advantages of this solution are at least as follows: the temperature can be displayed in real time through the temperature display module, and the indoor temperature can be seen more intuitively, improving the emergency response speed for abnormal air conditioner cooling.

[0022] A slave unit used in cooperation with the host includes a second housing, and further includes: A battery for supplying power to each unit module therein; An infrared receiving module for learning the functions of the air conditioner remote control; A human body sensing module for sensing the personnel activities in the monitoring area; A wireless communication module. When it is detected that there is no personnel activity and the time reaches the preset value, the controller automatically sends a shutdown command to the air conditioner or actively cuts off the power; The slave unit communicates with the host through the wireless communication module.

[0023] The advantages of this solution are at least as follows: The slave unit can be moved in position and used for the purpose of expanding the host and enhancing the signal. The slave unit communicates with the product host wirelessly. In a complex indoor environment, when the product host is blocked, there are also human body induction sensors and infrared emission components on the slave unit, which can enhance the adaptability of the product.

[0027] In summary, the present invention has at least the following advantages: This solution has the following innovative breakthroughs compared with the prior art: Breakthrough one: Human body induction infrared recognition technology. This technology enables a single host to recognize most areas, and at the same time, in cooperation with the movable slave unit, a space recognition rate of more than 98% can be achieved, solving the problem of blind spots in induction caused by different house types in the prior art. This means that regardless of the size of the room, this solution can accurately recognize and control the on / off state of the air conditioner equipment.

[0028] Breakthrough two: Solution to voltage problems. 99% of people, when the air conditioning cooling effect is not good, default that the refrigerant has been consumed, and the solution is generally to add refrigerant. However, in reality, many problems may lie in the voltage. This solution can monitor voltage anomalies and prompt users in a timely manner when problems are found, avoiding users' incorrect cognitions caused by unstable voltage, overcoming technical biases, and avoiding blind repairs.

[0029] Specifically, the main effects of the host and slave units of the present invention are as follows: Product host: 1. Through the infrared receiving module on the host, learn the air conditioner remote control function (including but not limited to the air conditioner shutdown function), and through the human body sensing module on the host, detect whether there are people moving indoors. When it is detected that there is no human activity and the time reaches the preset value (for example: 30 minutes), the product will automatically send a shutdown command to the air conditioner to turn off the air conditioner.

[0030] 2. When the product host detects that the air conditioner has been running continuously for a period of time but the temperature has not reached the obvious expectation, it will remind through the temperature anomaly indicator light.

[0031] 3. The product host can detect the power supply voltage of the air conditioner. When the voltage is insufficient and fluctuates by more than a certain amount (such as 5%), it will remind through the voltage anomaly indicator light.

[0032] 4. After the product host is powered on, it provides power for the air conditioner, meeting the national standard requirements (including but not limited to a maximum passing current of 16A). The product host is self-powered and does not have an external battery, directly taking power from the mains.

[0033] Product sub - machine: 1. The sub - machine communicates with the product host through a wireless communication module and can move freely. Due to the complex indoor environment, when the product host is blocked, there are also a human body induction sensor and an infrared emitting component on the sub - machine, which can enhance the adaptability of the product.

[0034] 2. The sub - machine is powered by a battery and has low power consumption through its own algorithm. Brief description of the drawings

[0035] Figure 1 Is an exploded schematic diagram of a preferred embodiment of the host; Figure 2 Is an overall schematic diagram of a preferred embodiment of the sub - machine.

[0036] Reference numerals in the drawings: 1, housing one; 2, plug; 3, socket; 4, first voltage anomaly indicator light; 5, first temperature anomaly indicator light; 6, first Fresnel hemisphere lens; 7, voltage display module; 8, temperature display module; 9, housing two; 10, battery; 11, second voltage anomaly indicator light; 12, second temperature anomaly indicator light; 13, second Fresnel hemisphere lens. Detailed implementation manners

[0037] The present invention will be further described in detail below with reference to the drawings.

[0038] An intelligent auxiliary host for air conditioner control, as Figure 1 shown, includes a housing one 1. One side of the housing one 1 is provided with a plug 2, and the other side is provided with a socket 3 electrically connected to the plug 2 for the air conditioner plug 2 to be inserted. The intelligent host is fixed in the socket beside the air conditioner as a power strip and can provide power for the air conditioner.

[0039] The host further includes: An infrared receiving module, which is composed of an infrared receiver and is electrically connected to the controller, and is used to learn the functions of the air conditioner remote control. The host and the air conditioner remote control are used independently. Through the infrared receiving module on the host, the functions of the air conditioner remote control (including but not limited to the air conditioner shutdown function) are learned.

[0040] The human body induction module is composed of a human body proximity sensor and is electrically connected to the controller, and is used to sense the personnel activities in the monitoring area.

[0041] The wireless communication module, when it detects that there is no personnel activity and the time reaches the preset value (such as 30 minutes), the controller automatically sends a shutdown instruction to the air conditioner or actively cuts off the power.

[0042] It is worth mentioning that, according to the data, as of 2020, the installed capacity of air conditioners in China was approximately 160 million kilowatts. Assuming that each air conditioner uses an average of 5,000 kilowatt-hours (kWh) of electricity per year, then the annual electricity consumption of air conditioners is approximately 800 billion kilowatt-hours (800,000,000,000 kWh). If more than 1% of people forget to turn off the air conditioner when going out, then the power saving benefit of the automatic shutdown of this solution will exceed 1 billion kilowatt-hours of electricity, greatly reducing the burden on China's power generation industry.

[0043] In some embodiments, the host also includes a voltage monitoring module and a first voltage anomaly indicator 4 electrically connected to the voltage monitoring module through the controller. When the voltage data fluctuation is greater than a specified amount (such as 5%), the first voltage anomaly indicator 4 lights up. Among them, the voltage monitoring module is composed of a device with voltage monitoring function in the prior art, and this device is electrically connected to the controller and the first voltage anomaly indicator 4.

[0044] In actual use, when there are multiple air conditioners running on a line, or the voltage instability caused by other situations will result in poor cooling effect of the air conditioner. At this time, it is easy for maintenance personnel to be maliciously guided to think that the air conditioner lacks refrigerant when they come to repair, resulting in the purchase and addition of refrigerant at a high price, and the problem of too high maintenance cost due to information asymmetry. The host of this solution can help users understand the voltage problem and take corresponding measures by real-time monitoring the voltage status and timely sending out anomaly prompts.

[0045] In some preferred embodiments, the host also includes a voltage display module 7 electrically connected to the voltage monitoring module through the controller. The voltage display module 7 is an existing device that can convert electrical signals into voltage data, which is convenient for consumers to more intuitively understand the voltage anomaly of the air conditioner.

[0046] In some embodiments, the host further includes a temperature sensing module and a first temperature anomaly indicator light 5 electrically connected to the temperature sensing module through a controller. When it is detected that the air conditioner has been running continuously for a specified time (such as 15 minutes) but the temperature has not reached the preset temperature, the first temperature anomaly indicator light 5 lights up. In some preferred embodiments, the host further includes a temperature display module 8 electrically connected to the temperature sensing module through a controller. The temperature display module 8 is an existing device that can convert electrical signals into temperature data, facilitating consumers to more intuitively understand the indoor temperature changes, thereby determining whether the refrigeration effect of the air conditioner is abnormal.

[0047] In some preferred embodiments, a first Fresnel hemispherical lens 6 for improving the detection and reception sensitivity is provided at the front ends of the infrared receiving module, the human body sensing module, the wireless communication module, and the temperature sensing module of the host. The Fresnel hemispherical lens belongs to the prior art. One side of its lens surface is a smooth surface, and the other side is engraved with concentric circles from small to large. Its texture is designed according to the principles of light interference and diffraction, as well as the requirements for relative sensitivity and reception angle. The Fresnel hemispherical lens will generate an alternating "blind zone" and "high-sensitivity zone" in front of the detector to improve its detection and reception sensitivity. When someone walks in front of the lens, the infrared rays emitted by the human body continuously alternate between entering the "blind zone" and the "high-sensitivity zone", so that the received infrared signal is input in the form of a pulsed signal with varying strength, thereby enhancing its energy amplitude.

[0048] As Figure 2 shown, in some embodiments, a slave unit used in conjunction with the host is disclosed, which includes a second housing 9 and also includes a battery 10 for supplying power to each unit module therein. In different embodiments, the battery 10 can be built-in or detachable, and neither will affect the portability and mobility performance of the slave unit.

[0049] The slave unit further includes an infrared receiving module for learning the functions of the air conditioner remote control, a human body sensing module for sensing the personnel activities in the monitoring area, and a wireless communication module. When it is detected that there is no personnel activity and the time reaches the preset value, the controller automatically sends a shutdown command to the air conditioner or actively cuts off the power. Among them, the functions of the infrared receiving module and the human body sensing module, and the wireless communication module and the corresponding modules of the aforementioned host are the same. In addition, the slave unit communicates with the host through the wireless communication module. Specifically, the wireless communication modules of the host and the slave unit are matched with the wireless communication module of the air conditioner, such as both using 2.4G or 5G wireless signals for communication.

[0050] In some embodiments, the slave unit also includes a voltage monitoring module and a second voltage anomaly indicator light 11 electrically connected to the voltage monitoring module through a controller. When the voltage data fluctuates by more than a specified amount, the second voltage anomaly indicator light 11 lights up. In a preferred embodiment, it further includes a temperature sensing module and a second temperature anomaly indicator light 12 electrically connected to the temperature sensing module through a controller. When it is detected that the air conditioner has been running continuously for a specified time but the temperature has not reached the preset temperature, the second temperature anomaly indicator light 12 lights up. In a preferred embodiment, a second Fresnel hemispherical lens 13 for improving the detection and reception sensitivity is provided at the front ends of the infrared receiving module, the human body sensing module, the wireless communication module, and the temperature sensing module of the slave unit.

[0051] Since the slave unit is movable and can cooperate with the master unit, the slave unit can be placed in different places as needed to expand the applicability of the master unit to complex environments. Specifically, when the indoor environment is complex and the master unit is blocked, there are also human body sensing sensors and infrared emitting components on the slave unit, which can enhance the adaptability of the product.

[0052] Through the aforementioned master unit (as shown in Figure 1 ), and the slave unit (as shown in Figure 2 ), the present invention also provides an air conditioner intelligent adjustment method, including a fixed master unit and a movable slave unit for controlling the air conditioner. When there is no human activity in the air conditioner temperature adjustment area within a certain time, the master unit and / or the slave unit turn off the air conditioner; when the voltage data input to the air conditioner fluctuates by more than a specified amount, the master unit and / or the slave unit give an anomaly prompt; when the air conditioner has been running continuously for a specified time but the temperature has not reached the preset temperature, the master unit and / or the slave unit give an anomaly prompt.

[0053] It is worth mentioning that the fixed master unit and the movable slave unit respectively refer to the master unit that can be fixedly plugged into an indoor socket and the slave unit that can be movably placed.

[0054] The working process and beneficial effects of the present invention are as follows: When in use, plug the master unit into other indoor sockets, and then plug the plug 2 of the air conditioner into the socket 3 of the master unit. The slave unit can be placed in different positions as needed to enhance the signal of the master unit.

[0055] This solution has the following innovative breakthroughs compared with the prior art: Breakthrough one: Human body sensing infrared recognition technology. This technology enables a master unit to recognize most areas, and at the same time, in cooperation with the movable slave unit, it can achieve a space recognition rate of more than 98%, solving the problem of blind spots in induction caused by different house types in the prior art. This means that regardless of the size of the room, this solution can accurately recognize and control the on / off state of the air conditioner equipment.

[0056] Breakthrough 2: Solution to voltage problems. When 99% of people experience poor air-conditioning cooling, they default to thinking that the refrigerant has been consumed, and the general solution is to add refrigerant. However, in reality, many problems may lie in the voltage. This solution can monitor voltage anomalies and promptly notify users when problems are detected, avoiding users' incorrect perceptions caused by unstable voltage, overcoming technical biases, and preventing blind repairs.

[0057] In addition, the main unit and sub-unit of the present invention mainly have the following effects: Product main unit: 1. Through the infrared receiving module on the main unit, learn the air-conditioning remote control function (including but not limited to the air-conditioning shutdown function). Through the human body sensing module on the main unit, detect whether there is human activity in the room. When no human activity is detected and the time reaches the preset value (for example: 30 minutes), the product will automatically send a shutdown command to the air conditioner to turn it off.

[0058] 2. When the product main unit detects that the air conditioner has been running for a period of time but the temperature has not reached the obvious expectation, it will remind through the temperature anomaly indicator light.

[0059] 3. The product main unit can detect the power supply voltage of the air conditioner. When the voltage is insufficient and exceeds a certain amount (such as 5%) and fluctuates, it will remind through the voltage anomaly indicator light.

[0060] 4. After the product main unit is powered on, it provides power for the air conditioner, meeting national standards requirements (including but not limited to a maximum passing current of 16A). The product main unit is self-powered and does not have an external battery 10, directly taking power from the mains.

[0061] Product sub-unit: 1. The sub-unit communicates with the product main unit through a wireless communication module and can move freely. Due to the complex indoor environment, when the product main unit is blocked, the sub-unit also has a human body induction sensor and an infrared emitting component, which can enhance the product's adaptability.

[0062] 2. The sub-unit is powered by a battery 10 and operates with low power consumption through its own algorithm.

[0063] In addition, compared with the prior art, the present invention adopts technologies such as infrared recognition, voltage detection, and temperature control, improving the energy-saving effect and safety of the air conditioner; the intelligent energy-saving air-conditioning main unit is easy to install, compatible with existing air-conditioning equipment, and can be widely used in various places; with the rapid development of the smart home market, the present invention has a high market demand and is expected to bring good economic benefits.

[0064] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included within the protection scope of the present invention.
