Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
All the internal machines of the multi-split air conditioner cannot run under the condition that the main internal machine is powered off. When the existing commercial multi-connected machine main internal machine fails, a main internal machine is automatically allocated according to the internal machine IP address, and because the main internal machine is automatically allocated, a user does not know which main internal machine is and the operating state condition of the main internal machine, so that the operating modes of all internal machines are easily in conflict with the mode desired by the user.
When the household multi-split air conditioner runs, the power supply switch of the main internal machine is tripped or the main internal machine is in fault, so that the main internal machine needs to be powered off. The system and the wire controller can report no fault of the main internal machine when the main internal machine has a fault or the power failure condition occurs, and all other internal machines need to be shut down. At this time, only the fault can be checked and cleared to recover the operation of the main internal machine, or a user manually adjusts one fault-free internal machine to be the main internal machine, however, in the earlier stage, the user generally does not know how to set the main internal machine because professional personnel go to the door for debugging and installation.
The invention provides a multi-split air conditioner control method. The air conditioner multi-split air conditioner comprises a main internal machine, an auxiliary main internal machine and at least one auxiliary internal machine. Optionally, any two internal machines can be set as a main internal machine and an auxiliary main internal machine respectively when the air conditioner multi-split air conditioner is debugged and installed, and the other internal machines are slave internal machines.
Fig. 1 is a method schematic diagram of an embodiment of a multi-split air conditioner control method provided by the invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method includes at least step S110, step S120, and step S130.
And step S110, judging whether the main internal machine and/or the auxiliary main internal machine of the air conditioner multi-split air conditioner exist or not.
Specifically, when the multi-split air conditioner runs, whether the main internal machine and/or the auxiliary main internal machine exist or not is judged, for example, whether the main internal machine and/or the auxiliary main internal machine power down or not is judged.
And step S120, controlling the operation of the air conditioner based on the operation mode of the main internal machine under the condition that the main internal machine exists.
Specifically, whether a main internal machine exists or not is judged, and the operation of the air conditioner is controlled based on the operation mode of the main internal machine under the condition that the main internal machine exists. In a specific embodiment, the air conditioner is controlled to operate according to the operation mode of the auxiliary main internal machine or the operation mode of the main internal machine according to whether the current operation mode of the main internal machine is an air supply mode.
Specifically, under the condition that a main internal machine exists, if the current operation mode of the main internal machine is not an air supply mode, controlling the air conditioner to operate according to the operation mode of the main internal machine; and if the operation mode of the main internal machine is an air supply mode, controlling the air conditioner to operate according to the operation mode of the auxiliary main internal machine. Wherein, control the air conditioner according to the operational mode operation of main internal unit includes: the method for enabling the slave internal machine to determine the running mode of the slave internal machine according to the running mode of the master internal machine and/or controlling the air conditioner to run according to the running mode of the auxiliary master internal machine comprises the following steps: and enabling the slave internal machine to determine the operation mode of the slave internal machine according to the operation mode of the auxiliary main internal machine. That is, when operating according to the operating mode of the main internal machine, the slave internal machine cannot be set to the operating mode opposite to that of the main internal machine, and/or, when operating according to the operating mode of the auxiliary main internal machine, the slave internal machine cannot be set to the operating mode opposite to that of the auxiliary main internal machine.
For example, when the main internal machine operates according to the operation mode of the main internal machine, when the main internal machine is in the cooling mode, other auxiliary internal machines can be set in the cooling mode, the air supply mode and/or the dehumidification mode; when the main internal machine is in a heating mode, other auxiliary internal machines can be set to be in an air supply mode and/or a heating mode. When the auxiliary main internal machine operates according to the operation mode of the auxiliary main internal machine, when the auxiliary main internal machine is in a refrigeration mode, other auxiliary internal machines can be set in a refrigeration mode, an air supply mode and/or a dehumidification mode; when the auxiliary main internal machine is in the heating mode, other auxiliary internal machines can be set in the air supply mode and/or the heating mode.
Preferably, whether the current indoor temperature reaches the set temperature is determined, and the air conditioner is controlled to operate according to the operation mode of the auxiliary main indoor unit or the operation mode of the main indoor unit according to whether the current operation mode of the main indoor unit is the air supply mode or not under the condition that the current indoor temperature reaches the set temperature. Namely, under the condition that a main internal machine exists and the current indoor temperature reaches the set temperature, if the current operation mode of the main internal machine is not the air supply mode, controlling the air conditioner to operate according to the operation mode of the main internal machine; and if the operation mode of the main internal machine is an air supply mode, controlling the air conditioner to operate according to the operation mode of the auxiliary main internal machine.
When the operation mode of the main internal machine is an air supply mode, if other auxiliary internal machines still operate according to the original operation mode, then at the moment, if one of the auxiliary internal machines is switched to a heating mode from the original refrigeration mode, unit mode conflict can be caused, because the main internal machine is the air supply mode, the operation mode of the whole machine does not have a fixed mode, so that the auxiliary internal machine can be switched between the refrigeration mode and the heating mode, and then the whole machine can not determine what mode to operate, therefore, in order to prevent the situation that the rest auxiliary internal machines do not know the operation refrigeration mode or the heating mode and further cause the mode conflict, the operation mode of the auxiliary main internal machine is required to be executed, and the unit has a basis for judging the mode.
More specifically, when the main internal machine exists and the indoor temperature reaches the set temperature, if the user switches the operation mode of the main internal machine from the cooling mode, the dehumidification mode or the heating mode to the air supply mode, the main internal machine operates according to the operation mode of the auxiliary main internal machine, and if the operation mode of the main internal machine maintains the original operation mode, i.e., the non-air supply mode, the main internal machine operates according to the operation mode of the main internal machine.
And step S130, under the condition that the main internal machine does not exist, if the auxiliary main internal machine exists, controlling the operation of the air conditioner based on the operation mode of the auxiliary main internal machine.
Specifically, if the main internal machine does not exist, for example, the main internal machine fails, it is determined whether the auxiliary main internal machine exists (for example, whether the auxiliary main internal machine fails), and if the auxiliary main internal machine exists, the auxiliary main internal machine is currently used as the main internal machine, and the operation of the air conditioner is controlled based on the operation mode of the auxiliary main internal machine.
In a specific embodiment, the air conditioner is controlled to operate according to the operation mode of the last slave internal machine with the set operation mode or according to the operation mode of the auxiliary main internal machine according to whether the current operation mode of the auxiliary main internal machine is the air supply mode.
Specifically, if the operation mode of the auxiliary main internal machine is not the air supply mode, controlling the air conditioner to operate according to the operation mode of the auxiliary main internal machine; and/or if the operation mode of the auxiliary main internal machine is an air supply mode, controlling the air conditioner to operate according to the operation mode of the last auxiliary internal machine with the operation mode set.
Because when the operation mode of the auxiliary main internal machine is an air supply mode, other auxiliary internal machines still operate according to the original mode, at the moment, if one of the auxiliary internal machines is switched from the original refrigeration mode to heating, unit mode conflict can be caused, because the operation mode of the auxiliary main internal machine (the current main internal machine) does not have a fixed mode when the operation mode is air supply, the auxiliary internal machine can be switched between the refrigeration mode and the heating mode, and then the whole machine can not determine what mode to operate.
Wherein, control the air conditioner according to the operation mode operation of the last slave indoor unit that has set up the operation mode, include: and enabling other slave internal machines to determine the operation mode of the other slave internal machines according to the operation mode of the last slave internal machine with the set operation mode. That is, when operating in the operation mode of the last slave internal unit in which the operation mode has been set, the other slave internal units cannot be set to the operation mode opposite to the operation mode of the last slave internal unit in which the operation mode has been set.
For example, when the last slave internal machine set to the operation mode is the cooling mode, other slave internal machines can set the cooling mode, the air supply mode and/or the dehumidification mode; when the last slave internal unit which is set to the running mode is the heating mode, other slave internal units can be set to the air supply mode and/or the heating mode.
Fig. 2 is a schematic method diagram of another embodiment of the multi-split air conditioner control method provided by the invention.
As shown in fig. 2, according to another embodiment of the present invention, the control method further includes step S140.
And step S140, under the condition that the main internal machine and the auxiliary main internal machine do not exist, controlling the operation of the air conditioner based on the operation mode of the last slave internal machine with the operation mode set.
And under the condition that the main internal machine and the auxiliary main internal machine do not exist, controlling the operation of the air conditioner based on the operation mode of the last slave internal machine with the operation mode set, namely switching the last slave internal machine with the operation mode set into the main internal machine.
In a specific embodiment, all the slave internal machines are controlled to operate according to the respective current operation modes or the operation mode of the slave internal machine with the last set operation mode according to whether the operation mode of the last slave internal machine with the set operation mode is the air supply mode or not. Specifically, if the operation mode of the last slave internal unit with the operation mode set is an air supply mode, all the slave internal units are controlled to operate according to the respective current operation modes; and/or if the operation mode of the last slave internal machine with the operation mode set is not the air supply mode, controlling all slave internal machines to operate according to the operation mode of the last slave internal machine with the operation mode set, namely enabling other slave internal machines to determine the operation mode of the other slave internal machines according to the operation mode of the last slave internal machine with the operation mode set. For a specific embodiment of controlling all the slave internal units to operate according to the operation mode of the last slave internal unit with the operation mode set, reference may be made to the description in the foregoing step, which is not repeated herein.
Optionally, a function switch for turning on or off the function of the switching main indoor unit is arranged on a controller (such as a wire controller) of the air conditioner multi-split air conditioner, and optionally, the function of the switching main indoor unit can be turned on by default. When the function of the switching main internal machine is started, the control method is executed.
In order to clearly illustrate the technical solution of the present invention, an execution flow of the multi-split air conditioner control method provided by the present invention is described below with a specific embodiment. Fig. 3 is a method schematic diagram of an embodiment of a multi-split air conditioner control method provided by the invention.
As shown in fig. 3, the multi-split air conditioner normally operates, determines whether the main internal unit exists, determines whether the operation mode of the main internal unit is the air supply mode when the main internal unit exists and the room temperature reaches the set temperature, and operates according to the operation mode of the auxiliary main internal unit if the operation mode of the main internal unit is the air supply mode (for example, the user switches the operation mode of the main internal unit from the cooling mode, the dehumidification mode or the heating mode to the air supply mode); if the mode of the main internal machine maintains the original operation mode, namely the non-air supply mode, the main internal machine operates according to the operation mode of the main internal machine; if the main internal machine does not exist (for example, the main internal machine is powered off), judging whether an auxiliary main internal machine exists, if the auxiliary main internal machine exists, judging whether the operation mode of the auxiliary main internal machine is an air supply mode, and if the operation mode of the auxiliary main internal machine is a non-air supply mode, operating the unit according to the operation mode of the auxiliary main internal machine; and if the operation mode of the auxiliary main internal machine set by the user is the air supply mode, operating according to the operation mode of the last auxiliary internal machine with the operation mode set. When the main internal machine and the auxiliary main internal machine do not exist, namely the main internal machine and the auxiliary main internal machine are powered off, the last slave internal machine set with the running mode is switched to be the main internal machine. If the operation mode of the last slave internal machine with the operation mode set is an air supply mode, all the slave internal machines operate according to the respective current operation modes, otherwise, the slave internal machines operate according to the current operation mode of the last slave internal machine with the operation mode set, namely, other slave internal machines determine the operation modes of the slave internal machines according to the operation mode of the last slave internal machine with the operation mode set.
The invention also provides a multi-split air conditioner control device. The air conditioner multi-split air conditioner comprises a main internal machine, an auxiliary main internal machine and at least one auxiliary internal machine. Optionally, any two internal machines can be set as a main internal machine and an auxiliary main internal machine respectively when the air conditioner multi-split air conditioner is debugged and installed, and the other internal machines are slave internal machines.
Fig. 4 is a schematic structural diagram of an embodiment of an air conditioner multiple on-line control device provided by the invention. As shown in fig. 4, the multi-split air conditioner control device 100 includes a determination unit 110 and a control unit 120.
The judging unit 110 is configured to judge whether a main internal unit and/or an auxiliary main internal unit of the air conditioner multi-split air conditioner exists; the control unit 120 is configured to control the operation of the air conditioner based on the operation mode of the main internal machine in the presence of the main internal machine; and/or under the condition that the main internal machine does not exist, if the auxiliary main internal machine exists, controlling the operation of the air conditioner based on the operation mode of the auxiliary main internal machine.
The determining unit 110 determines whether the main internal unit and/or the auxiliary main internal unit of the air conditioning multi-split air conditioner exist. Specifically, when the multi-split air conditioner is running, the determining unit 110 determines whether the main internal unit and/or the auxiliary main internal unit exist, for example, whether the main internal unit and/or the auxiliary main internal unit are powered off.
The control unit 120 controls the operation of the air conditioner based on the operation mode of the main internal machine in the case where the determination unit 110 determines that the main internal machine exists. Specifically, the determination unit 110 first determines whether a main internal unit exists, and the control unit 120 controls the operation of the air conditioner based on the operation mode of the main internal unit when the determination unit 110 determines that the main internal unit exists. In a specific embodiment, the control unit 120 controls the air conditioner to operate according to the operation mode of the auxiliary main internal machine or according to the operation mode of the main internal machine according to whether the current operation mode of the main internal machine is the air supply mode. Wherein, the control unit 120 controls the air conditioner to operate according to the operation mode of the main internal unit, including: the method for enabling the slave internal machine to determine the running mode of the slave internal machine according to the running mode of the master internal machine and/or controlling the air conditioner to run according to the running mode of the auxiliary master internal machine comprises the following steps: and enabling the slave internal machine to determine the operation mode of the slave internal machine according to the operation mode of the auxiliary main internal machine. That is, when operating according to the operating mode of the main internal machine, the slave internal machine cannot be set to the operating mode opposite to that of the main internal machine, and/or, when operating according to the operating mode of the auxiliary main internal machine, the slave internal machine cannot be set to the operating mode opposite to that of the auxiliary main internal machine.
For example, when the main internal machine operates according to the operation mode of the main internal machine, when the main internal machine is in the cooling mode, other auxiliary internal machines can be set in the cooling mode, the air supply mode and/or the dehumidification mode; when the main internal machine is in a heating mode, other auxiliary internal machines can be set to be in an air supply mode and/or a heating mode. When the auxiliary main internal machine operates according to the operation mode of the auxiliary main internal machine, when the auxiliary main internal machine is in a refrigeration mode, other auxiliary internal machines can be set in a refrigeration mode, an air supply mode and/or a dehumidification mode; when the auxiliary main internal machine is in the heating mode, other auxiliary internal machines can be set in the air supply mode and/or the heating mode.
Specifically, in the presence of a main internal machine, if the current operation mode of the main internal machine is not the air supply mode, the control unit 120 controls the air conditioner to operate according to the operation mode of the main internal machine; if the operation mode of the main internal machine is the air supply mode, the control unit 120 controls the air conditioner to operate according to the operation mode of the auxiliary main internal machine.
Preferably, it is determined whether the current indoor temperature has reached the set temperature, and the control unit 120 controls the air conditioner to operate according to the operation mode of the auxiliary main internal unit or according to the operation mode of the main internal unit according to whether the current operation mode of the main internal unit is the air supply mode when the current indoor temperature has reached the set temperature. Namely, under the condition that a main internal machine exists and the current indoor temperature reaches the set temperature, if the current operation mode of the main internal machine is not the air supply mode, controlling the air conditioner to operate according to the operation mode of the main internal machine; and if the operation mode of the main internal machine is an air supply mode, controlling the air conditioner to operate according to the operation mode of the auxiliary main internal machine.
When the operation mode of the main internal machine is an air supply mode, if other auxiliary internal machines still operate according to the original operation mode, then at the moment, if one of the auxiliary internal machines is switched to a heating mode from the original refrigeration mode, unit mode conflict can be caused, because the main internal machine is the air supply mode, the operation mode of the whole machine does not have a fixed mode, so that the auxiliary internal machine can be switched between the refrigeration mode and the heating mode, and then the whole machine can not determine what mode to operate, therefore, in order to prevent the situation that the rest auxiliary internal machines do not know the operation refrigeration mode or the heating mode and further cause the mode conflict, the operation mode of the auxiliary main internal machine is required to be executed, and the unit has a basis for judging the mode.
More specifically, when the main internal machine exists and the indoor temperature reaches the set temperature, if the user switches the operation mode of the main internal machine from the cooling mode, the dehumidification mode or the heating mode to the air supply mode, the main internal machine operates according to the operation mode of the auxiliary main internal machine, and if the operation mode of the main internal machine maintains the original operation mode, i.e., the non-air supply mode, the main internal machine operates according to the operation mode of the main internal machine.
If the determination unit 110 determines that the auxiliary main internal unit exists under the condition that the main internal unit does not exist, the operation of the air conditioner is controlled based on the operation mode of the auxiliary main internal unit.
Specifically, if the main internal machine does not exist, for example, the main internal machine fails, the determining unit 110 determines whether the auxiliary main internal machine exists (for example, whether the auxiliary main internal machine fails), and if the auxiliary main internal machine exists, the auxiliary main internal machine is currently used as the main internal machine, and the control unit 120 controls the operation of the air conditioner based on the operation mode of the auxiliary main internal machine.
In a specific embodiment, the control unit 120 controls the air conditioner to operate according to the operation mode of the last slave internal unit with the operation mode set or according to the operation mode of the auxiliary master internal unit according to whether the current operation mode of the auxiliary master internal unit is the air supply mode.
Specifically, if the operation mode of the auxiliary main internal machine is not the air supply mode, the control unit 120 controls the air conditioner to operate according to the operation mode of the auxiliary main internal machine; and/or, if the operation mode of the auxiliary main internal machine is the air supply mode, the control unit 120 controls the air conditioner to operate according to the operation mode of the last slave internal machine with the operation mode set.
Because when the operation mode of the auxiliary main internal machine is an air supply mode, other auxiliary internal machines still operate according to the original mode, at the moment, if one of the auxiliary internal machines is switched from the original refrigeration mode to heating, unit mode conflict can be caused, because the operation mode of the auxiliary main internal machine (the current main internal machine) does not have a fixed mode when the operation mode is air supply, the auxiliary internal machine can be switched between the refrigeration mode and the heating mode, and then the whole machine can not determine what mode to operate.
Wherein, the control unit 120 controls the air conditioner to operate according to the operation mode of the last slave internal unit with the operation mode set, including: and enabling other slave internal machines to determine the operation mode of the other slave internal machines according to the operation mode of the last slave internal machine with the set operation mode.
