The indoor unit may generally comprise: a machine shell 500, an indoor unit heat exchanger and a fan. Wherein, the casing 500 has the function of holding and fixing, and the indoor heat exchanger and the fan can be arranged inside the casing 500.
The heat exchange system 300 may be implemented using a compression refrigeration cycle, which uses a compression phase change cycle of a refrigerant in a compressor, a condenser, an evaporator, and a throttling device to implement heat transfer. In the air conditioner 10, the heat exchange system 300 may further include a four-way valve to change the flow direction of the refrigerant, so that the indoor heat exchanger is alternately used as an evaporator or a condenser to achieve the cooling or heating function. Since the compression refrigeration cycle of the air conditioner 10 is well known to those skilled in the art, the operation principle and structure thereof will not be described herein. The fan is used for promoting the heat exchange air flow passing through the heat exchanger of the indoor unit to pass through the air supply outlet 501 of the indoor unit and be blown to the indoor environment. The air supply opening 501 may be opened in the casing 500, and may be located at an upper portion of the indoor unit.
The humidification module 200 is provided in the indoor unit of the air conditioner 10, and may be provided in the cabinet 500, for example. The humidification module 200 is configured to generate an atomized water flow and to promote the atomized water flow to be discharged to the indoor environment, thereby increasing the humidity of the indoor environment. The humidifying module 200 may be disposed at a lower portion, a middle portion or an upper portion of the indoor unit.
In this embodiment, the humidification module 200 may be disposed adjacent to the air supply outlet 501, for example, may be disposed substantially below the air supply outlet 501.
The humidification module 200 may include: water tank, atomizing motor, induced air fan, electric heater unit. Humidification module 200 also has an air inlet and an air outlet.

The air outlet of the humidification module 200 may be disposed opposite to the air supply outlet 501 of the air conditioner 10. For example, the air outlet may be disposed inside the air blowing opening 501, so that the atomized water flow can be blown out along with the air flow of the air conditioner 10, thereby increasing the humidity of the air flow and improving the air blowing comfort of the air conditioner 10 with the humidifying module 200.
In some optional embodiments, the humidifying module 200 may be disposed at a lower portion of the indoor unit and far away from the air supply outlet 501, so that the atomized water flow and the air supply flow do not interfere with each other, and the air conditioner 10 of the present embodiment can adjust the humidity and the temperature of the indoor environment separately or simultaneously.
And the water tank is used for containing liquid water. And the atomizing motor is used for promoting the liquid water to be converted into atomized water. The atomizing motor may be disposed on the bottom wall of the water tank. And the induced draft fan is used for promoting the atomized water to form atomized water flow and promoting the atomized water flow to blow from the air outlet of the humidification module 200 to the inner side of the air supply outlet 501 of the air conditioner 10.

The indoor unit of the air conditioner 10 may be provided with a status parameter monitoring device 100, configured to detect a status parameter of an indoor environment where the air conditioner 10 is located, so as to obtain relevant information. The state parameter of the indoor environment in which the air conditioner 10 is located is used to represent the quality of the air in the indoor environment. The state parameters may include any combination of a number of parameters: temperature, humidity, bacterial count, odor size, particulate contaminant content. The state parameter monitoring device 100 may be plural, and includes: the device comprises a temperature sensor, a humidity sensor, a bacteria quantity sensor, an odor concentration sensor and a particle pollutant content sensor which are respectively used for detecting the temperature, the humidity, the bacteria quantity, the odor size and/or the particle pollutant content of the indoor environment. The condition parameter monitoring device 100 may be one, and may have a plurality of different detection units for detecting the plurality of condition parameters, respectively. The condition parameter monitoring device 100 may be disposed on the housing 500. In other embodiments, the air conditioner 10 may also obtain the above status parameters through other external status parameter monitoring devices 100.
The humidity in this embodiment may refer to relative humidity.
The control device 400 includes a memory 420 and a processor 410, wherein a control program 421 is stored in the memory 420, and the control program 421 is executed by the processor 410 to implement the control method of the air conditioner 10 according to any one of the following embodiments. The processor 410 may be a Central Processing Unit (CPU), or a digital processing unit (DSP), etc. The memory 420 is used to store programs executed by the processor 410. The memory 420 may be any medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited to such.

The air conditioner 10 in this embodiment may have a plurality of different operation modes including at least a cooling mode, a heating mode, and a humidifying mode. The humidifying mode can be operated simultaneously with the cooling mode or the heating mode, and can also be operated independently. The humidification mode may include an automatic humidification mode and a manual humidification mode. The automatic humidification mode is automatically turned on by the air conditioner 10 itself, and the manual humidification mode is instructed by the user that the air conditioner 10 is turned on. In some alternative embodiments, the above operation modes may further include a PMV (human comfort intelligent control) mode in which the air conditioner 10 may automatically determine the temperature of cooling/heating according to the temperature of the indoor environment.
Fig. 3 is a schematic diagram of a control method of the air conditioner 10 having the humidification module 200 according to an embodiment of the present invention. The control method of the air conditioner 10 may generally include:
in step S302, a power-on command of the humidification module 200 of the air conditioner 10 is obtained.
In the case where the humidifying function is not required, the humidifying module 200 of the air conditioner 10 is in a stopped state. The humidification module 200 may switch to a standby state after receiving a power-on command. The humidification module 200 in the standby state may be switched to the operating state and generate the atomized water flow after receiving the start instruction sent by the processor 410.
The power-on command may include an automatic humidification command determined by the air conditioner 10 itself, and a manual humidification command received by the air conditioner 10 and issued by the user.
The air conditioner 10 may receive a manual humidification command issued by a user through a voice signal processing unit or other signal processing unit. The manual humidification command may be a power-on instruction of the humidification mode issued by the user through voice or by triggering a corresponding key on a remote control panel that is configured with the air conditioner 10, and is used to instruct the air conditioner 10 to switch the humidification module 200 to the standby state according to the instruction of the user.
The air conditioner 10 may also automatically determine whether the automatic humidification mode needs to be started by collecting the state parameters of the indoor environment detected by the state parameter monitoring device 100 and the operation information of the air conditioner 10, thereby automatically issuing an automatic humidification command. The automatic humidification command may be a power-on instruction of the humidification module 200 issued by the processor 410 of the air conditioner 10, for instructing the humidification module 200 to switch to the standby state. In some alternative embodiments, the auto-humidification command may be issued when the air conditioner 10 is in the PMV mode.
In some alternative embodiments, the automatic humidification commands may be issued periodically at preset time intervals. The time interval can be set by the user according to actual needs.
In this embodiment, the state parameter monitoring device 100 may detect the humidity of the indoor environment every first preset time, and the automatic humidification command may be issued when the humidity of the indoor environment is lower than a preset set humidity. In some alternative embodiments, the auto-humidification command may also be issued when the particulate contaminant content is above a preset content threshold.
In step S304, the initial humidity of the indoor environment in which the air conditioner 10 is located and the operation information of the air conditioner 10 are acquired.
The initial humidity is the humidity of the indoor environment after the humidification module 200 is switched to the standby state. For example, the humidity of the indoor environment collected by the state parameter monitoring apparatus 100 may be used as the initial humidity. The operation information includes a set temperature and/or a set humidity at which the air conditioner 10 operates. Wherein the set humidity may include a first set humidity and a second set humidity. The first set point humidity may be less than the second set point humidity. The first set humidity is a set humidity that a user may want to reach when the air conditioner 10 is automatically operated, and the second set humidity is a set humidity that a user may want to reach when the user may want to control the operation of the air conditioner 10 through a manual humidification command.
The set temperature and/or the set humidity may be preset by a user according to actual needs. For example, if the set temperature is 25 ℃, it indicates that the user wishes the air conditioner 10 to operate such that the temperature of the indoor environment is 25 ℃ or maintained; if the first set humidity is 70%, it indicates that the user desires the air conditioner 10 to automatically operate so that the humidity of the indoor environment can be maintained at 70% or more; if the second set humidity is 75%, it indicates that the user wishes to control the operation of the air conditioner 10 by a manual humidification command and to maintain the humidity of the indoor environment at or above 75%.
