The present application claims priority to Chinese Patent Application No. 201810332049.5, entitled “Controller of Air-Conditioning Unit, and Air-Conditioner”, and filed with the China National Intellectual Property Administration on Apr. 13, 2018, the entire content of which is hereby incorporated by reference herein.
The present disclosure relates to a field of air-conditioning control technology, and particularly to a controller of an air-conditioning unit and an air-conditioner.
In related technologies, devices in a multi-split system, such as an outdoor unit, an indoor unit, a wired remote controller and the like, all use a communication mode such as CAN, 485, HBS and so on. However, these communication modes require an installation personnel to arrange dedicated communication lines, which involves problems of additional construction, complicated wiring, high cost and difficult maintenance or the like. In addition, an air-conditioning controller, such as a wired remote controller and a centralized controller, is generally installed and fixed on a wall by a screw, and cannot be moved optionally; and if no extra mounting hole (or an installation box) is reserved for the air-conditioning controller in a room, a dedicated mounting hole (or installation box) needs to be added to install the air-conditioning controller.
When a controller of an air-conditioning unit controls an operation of the air-conditioning unit, it is needed to provide a dedicated mounting device to fix the controller. The controller is inconvenient to use, resulting in a technical problem of reduced user experience. Currently, no effective solution has been proposed.
Some embodiments of the present disclosure provide a controller of an air-conditioning unit and an air-conditioner, to at least solve technical problems that the controller of the air-conditioning unit needs to be fixed by providing a dedicated installation device when controlling an operation of the air-conditioning unit, and thus the use of the controller is inconvenient, and user experience is reduced.

Exemplary embodiments of the present disclosure and the description thereof are used for explaining the present disclosure, and do not constitute an improper limitation to the present disclosure. In the drawings:
In order to enable those skilled in the art to better understand the solution of the present disclosure, technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.
It should be noted that terms “first” and “second” in the description, claims and the above-mentioned drawings of the present disclosure are used for distinguishing similar objects, but not definitely used for describing a specific sequence or order. It should be understood that data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, terms “including” and “having” and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or unit is not definitely limited to those clearly listed steps or units, and may include other steps or units that are not clearly listed or are inherent to these process, method, product, or device.
In order to facilitate a user to understand the present disclosure, some terms or nouns involved in each embodiment of the present disclosure are explained below.
Power Line Communication (PLC) is a unique communication mode to a power system. The PLC refers to a technology of use of an existing power line to transmit an analog or digital signal at a high speed by means of a carrier wave.
The following embodiments of the present disclosure can be applied to a multi-split air-conditioning system. The multi-split air-conditioning system may include an air-conditioner outdoor unit, an air-conditioner indoor unit, a wire controller and other devices. In related technologies, when an air-conditioning unit is controlled by a controller, it is required to provide a dedicated device or equipment (such as an installation box) for the controller to fix the controller, so as to use the controller. In the present disclosure, the controller is provided to have a plug-in mounting mode. By providing a pin, the controller can be plugged into any socket in the PLC communication network, to make the controller connected to a network of each air-conditioner indoor unit and an air-conditioner outdoor unit. The user can use the air-conditioning controller to control the air-conditioner indoor unit and the air-conditioner outdoor unit in the air-conditioning unit and control an operation state of the air-conditioning unit. When a position of the controller needs to be changed, the controller only needs to be unplugged and plugged into another socket, achieving a purpose of plugging and unplugging.
In the embodiment of the present disclosure, the controller can be plugged into the socket to realize an operation control of each device in the air-conditioning unit through the pre-established power line communication (PLC). The controller in the present disclosure can implement the control through the socket, and the air-conditioner indoor unit and the air-conditioner outdoor unit connected to the socket, the transmission of the communication signal is implemented through a power line.
The plug component 1201 is configured to plug into a socket in a preset PLC communication network. The plug component can be directly plugged into any socket in the PLC communication network, without needing to provide a dedicated installation box to install the controller, which reduces a cost of installing the device. Moreover, an installation position of the controller can be changed optionally through the plug-in mounting mode, i.e., only the plug component 1201 is utilized to change the position of the controller without moving the installation box of the controller, accordingly the controller can be quickly moved to a target position.
Alternatively, the plug component may include at least one of the following: a two-pin plug component and a three-pin plug component. The plug component of the present disclosure can be applied to various sockets, and not only satisfies a two-pin power socket, but also satisfies a three-pin power socket, and thus has a wider application range.
Preferably, the plug component in the embodiment of the present disclosure can be moved optionally, such as being moved up and down. When the controller needs to be moved to the target position, the controller can be manually moved to the target position. After the plug component is moved to the target position, the plug component can be fixed by a limit module. The plug component in the embodiment of the present disclosure can be applied to different jacks of the socket, such as a two-pin jack or a three-pin jack, such that the air-conditioning controller can maintain practicality after being plugged into the socket. The controller in the embodiment of the present disclosure can be moved up and down. For example, if the jack of the socket is in an upper position, the plug component of the air-conditioning controller can be moved up to the target position and then plugged into the socket. If the jack of the socket is in a lower position, the plug component of the controller can be moved down to the target position and then plugged into the socket. In this way, the controller is kept in a nice position.
The controller body component 1202 is connected to the plug component, and is configured to receive a communication signal of a target device and transmit the communication signal to a device matching the target device. The target device includes one of the air-conditioner indoor unit and the air-conditioner outdoor unit.
The above-mentioned controller body component 1202 can be used as a main component of a controller to control the operation of the air-conditioning unit. After the controller is moved to the target socket by using the plug component and the controller is plugged into the socket, the operations of the air-conditioner indoor unit and the air-conditioner outdoor unit in the air-conditioning unit can be controlled through the pre-established PLC communication network. That is, the operation of the air-conditioner indoor unit or the air-conditioner outdoor unit can be controlled by the controller 12.
When controlling the air-conditioning unit, the above-mentioned air-conditioning controller can be directly plugged into the socket, and the position of the controller can be moved optionally. If another air-conditioning unit needs to be controlled, the controller can be plugged into a next socket to implement a control of another air-conditioning unit. In the embodiment of the present disclosure, the operation of the air-conditioner outdoor unit or the air-conditioner indoor unit in the air-conditioning unit can be controlled by the controller. In the embodiment, after the position of the controller is changed, the original air-conditioning unit in the PLC network can also be controlled. That is, according to the present disclosure, if the installation position of the controller needs to be changed, it is only needed to unplug the controller and plug it into another socket to control the original air-conditioning unit, accordingly the position of the controller in each socket can be flexibly adjusted. After the PLC communication network is established, the operation of the air-conditioning unit is controlled by the air-conditioning controller, and the air-conditioning controller is directly plugged into any socket in the PLC communication network through a plug-in mounting mode, without needing a dedicated installation box. The installation position of the controller can be changed optionally, and the controller can be moved to any place as desire to control the air conditioning, thereby solving the technical problem that a dedicated installation device needs to be provided to fix the controller when the controller of the air-conditioning unit controls the operation of the air-conditioning unit, causing inconvenient use of the controller and reduced user experience.
Alternatively, the above-mentioned controller body component includes: a power line communication module which receives a communication signal of a target device through a power line; and a processor module connected to the power line communication module and configured to analyze the communication signal and obtain an analysis result. Alternatively, the processor module is further configured to transmit a target control instruction to a target indoor unit or a target outdoor unit through the power line communication module. The target control instruction is configured to control an operation of the target indoor unit or the target outdoor unit. That is, the analysis of the communication signal can be implemented by the processor module i.e., corresponding communication information can be received. Moreover, the processor module used as a control body can transmit a corresponding control instruction to other air-conditioning devices, for example, a control instruction is transmitted to the target indoor unit or the target outdoor unit through the communication module.
In addition to the power line communication module, the processor module and the like, the above-mentioned controller body component may further include a display module and a key-press module. The display module is configured to display operation information and state information of the air-conditioning unit. The key-press module receives key-press operation information. That is, a current operation condition of the air-conditioning unit can be displayed through the display module, and the user can know the current state of the air-conditioning unit through the display module.
Alternatively, the processor module not only can be connected to the above-mentioned power line communication module to receive and analyze the communication signal of the communication module, but also can be connected to the display module and the key-press module. The processor module can control the display module to display a content to be displayed (that is, the operation information and state information of the above-mentioned air-conditioning unit). At the same time, the processor can also receive and process the key-press operation information transmitted by the key-press module, and perform a corresponding action according to the key-press operation information. The key-press operation information transmitted by the key-press module can also be a control instruction, and operations of other air-conditioning devices (such as air-conditioner indoor unit or air-conditioner outdoor unit) are controlled by the control instruction.
Control of the air-conditioner indoor unit and the air-conditioner outdoor unit in the air-conditioning unit can be implemented through various modules in the above-mentioned controller body component. Moreover, when the communication information or the control instruction corresponding to the key-press operation performed by the key-press module is received, corresponding information can be processed by the processor module, and then information can be transmitted to a corresponding target communication device.
It should be noted that there are a plurality of types of controllers in the embodiments of the present disclosure, as long as a module configured to control the air-conditioning unit is used as one controller. For example, the controller can be a wired remote controller, and the wired remote controller acquires the communication information transmitted by the air-conditioner indoor unit or the air-conditioner outdoor unit through the PLC communication network. In addition, the wired remote controller used as the control body can also transmit the control instruction to the target device (i.e., the above-mentioned air-conditioner indoor unit or the air-conditioner outdoor unit). Accordingly, the control of the air-conditioner indoor unit or the air-conditioner outdoor unit is implemented through the wired remote controller, and a normal operation of the air-conditioning unit is implemented.
Alternatively, the control instruction transmitted by the wired remote controller and the target control instruction transmitted by the processor module in the embodiments of the present disclosure mentioned above may both be used as a control mode, and a content of the control instruction is not limited.
In addition, a type of the controller may also include a centralized controller and a gateway. The centralized controller is configured to centrally control the plurality of air-conditioner outdoor units and/or the plurality of air-conditioner indoor units to perform a target action according to a control instruction after the control instruction is received. The gateway is configured to connect a preset external device to the PLC communication network to control the air-conditioner outdoor unit or the air-conditioner indoor unit. The control of each air-conditioner indoor unit or air-conditioner outdoor unit can be implemented by the centralized controller, and the normal operation of the air-conditioning unit can also be implemented. The air-conditioning unit can be connected to the external device by using the gateway. The user can transmit the control instruction through the external device so as to implement the control of the air-conditioner indoor unit and the air-conditioner outdoor unit. The gateway can be used as a communication interface to exchange communication data.
Alternatively, the plurality of air-conditioner outdoor units may include one central outdoor unit which is configured to provide a network Internet Protocol (IP) address for each network device in the PLC communication network. The network IP address is configured to identify each network device. After receiving the communication data transmitted by the air-conditioner outdoor unit or the air-conditioner indoor unit, the central outdoor unit forwards the communication data to a target communication device.
The central outdoor unit in the above-mentioned embodiment can provide a network IP address for each network device in the PLC communication network. A plurality of types of devices, such as a plurality of air-conditioner outdoor units, a plurality of air-conditioner indoor units, a plurality of wired remote controllers, a centralized controller, a gateway or the like, may be included in the PLC communication network in the embodiments of the present disclosure. All these devices can be connected to the power line to perform the PLC network communication. Each device can have an independent Media Access Control (MAC) address, and all devices form a PLC communication multi-split system network through a PLC networking mechanism. The central outdoor unit can be used as a communication main body, and as a main body of a connection (central outdoor unit) to receive the information transmitted by the preset device (the air-conditioner outdoor unit, the air-conditioner indoor unit, the plurality of wired remote controllers, the centralized controller and the gateway), and transmit the information transmitted by the preset device to the target device.
Preferably, after the controller in the embodiment of the present disclosure is plugged into one socket in the PLC communication network, the transmission of the communication information is implemented through a pre-established PLC communication connection between the air-conditioner indoor unit and the air-conditioner outdoor unit, and then the operation of the air-conditioning unit is controlled by the controller. When needed, the controller can be unplugged and plugged into the next socket, in such a way, the normal communication between the original air-conditioner indoor unit and air-conditioner outdoor unit in the PLC communication network can be maintained. That is, the control of the air-conditioner indoor unit or the air-conditioner outdoor unit can be implemented through the controller.
In the embodiment of the present disclosure, the controller can be moved arbitrarily. It is only needed to directly plug the air-conditioning controller into the socket in a room through the plug component, the control of the operations of the air-conditioner indoor unit and the air-conditioner outdoor unit in the PLC communication network can be implemented. The air-conditioning controller can also be moved to another socket optionally, and can still control the air-conditioning unit in the PLC communication.
Alternatively, the aforementioned PLC communication network can connect a plurality of outdoor units including a main outdoor unit, an outdoor unit 2, . . . , and an outdoor unit N. A control signal can be transmitted by the main outdoor unit. Moreover, the present disclosure can implement a connection of the centralized controller, the debugger or the gateway or the like without a communication line. The main outdoor unit may include a PLC modulation device of the PLC network communication. The PLC modulation device, used as a central coordinator CCO of the entire PLC network, can make all devices in the PLC network receive and transmit data through the power line. Moreover, if a certain device needs to transmit data to a specific target device, the device firstly transmits the data, and after the data is received by the CCO (i.e., the outdoor unit), the CCO forwards the data to a corresponding target device, and the target device performs a corresponding action after receiving the data from the CCO.
The wired remote controller, the centralized controller, the gateway or the like in the networking system in the embodiment of the present disclosure can all be used as the air-conditioning controller. There are a plurality of types of air-conditioning controllers in the present disclosure, and the present disclosure does not limit a specific type of air-conditioning controller.
Alternatively, in the contents shown in
The air-conditioning controller has a plug component. Through the plug component, it is only needed to directly plug the air-conditioning controller into the socket in the room to participate in the networking and communicate with other devices in the network. After the networking is completed, the air-conditioning controller can be optionally moved to other sockets connected to the original PLC network, and can still communicate with the other devices normally.
Alternatively, the plug component of the air-conditioning controller in the present disclosure can be moved up and down, and can be limited and fixed after being moved to a desired position in order to meet different jack positions in different sockets, so that after being plugged into the socket, the air-conditioning controller can be kept centered with the socket, which is more beautiful. For example, if the jack of the socket is in an upper position, the plug component of the air-conditioning controller can be moved up to an appropriate position, and then plugged into the socket; if the jack of the socket is in a lower position, the plug component of the air-conditioning controller can be moved down to an appropriate position and then plugged into the socket.
According to another aspect of the embodiments of the present disclosure, an air-conditioner is further provided, which can include the controller of the air-conditioning unit described in any of the above embodiments.
