The air conditioner provided by the invention, as shown in fig. 1 and fig. 2, comprises a shell 1, an air outlet 2, an anion generator 3 and a fan 4; the air outlet 2 is arranged on the shell 1, the anion generator 3 is arranged at the air outlet 2, and the fan 4 is arranged inside the shell 1.
After the negative ion generator 3 is powered on and started, the emission head generates negative ions, and flowing air generated by the operation of the fan 4 is brought into a room, so that the indoor air can be sterilized and purified, and the occurrence of human air conditioning diseases is prevented; the negative ion generator 3 can be arranged on the outer side, the inner side and both ends of the air outlet 2.
As shown in fig. 3, in the air conditioner of the present invention, the controller 5 includes an external sterilizing module 51 and an internal sterilizing module 52; the external sterilization module 51 is used for starting the negative ion generator 3 and controlling the fan 4 to operate in the positive direction during the operation of the air conditioner, so that the negative ions generated by the negative ion generator 3 are driven to the indoor space to sterilize the indoor space; the internal sterilization module 52 is configured to start the anion generator 3 when receiving an internal sterilization instruction, and control the fan 4 to run in reverse, so that the anions generated by the anion generator 3 are driven to the inside of the air conditioner to sterilize the inside of the air conditioner.
The normal rotation and the reverse rotation are relative, and the reverse rotation is counterclockwise when the normal rotation is clockwise, and the reverse rotation is clockwise when the normal rotation is counterclockwise. After receiving the internal sterilization instruction, the internal sterilization module 52 starts the anion generator 3 if the current air conditioner is in the standby state, and maintains the anion generator 3 to continue operating if the current air conditioner is in the operating state.
In the invention, on the basis of the existing air conditioner with the anion sterilization function, the anion generated by the anion generator 3 is reversely carried into the air conditioner through the fan 4 in a mode of changing the running direction of the fan 4 after receiving an internal sterilization instruction, so as to sterilize the sterilization blind area in the air conditioner, realize bidirectional sterilization based on logic control of the air conditioner on the premise of not increasing the design cost of the air conditioner, and solve the technical problem that the interior of the existing air conditioner adopting the anion to sterilize indoors cannot be effectively sterilized.
The internal sterilization module 52 may perform sterilization according to a preset time length, a preset rotation speed of the fan 4, and the like after starting the internal sterilization of the air conditioner.
The internal sterilization command may be generated automatically by the air conditioner when a set condition is reached, or by receiving an external control signal, for example, a signal transmitted by a user through a remote controller, a smart terminal, or the like.
The set condition includes, but is not limited to, reaching a preset time interval, reaching a set time period of the operation of the external sterilization module 51, or exceeding a preset value of sensor data, such as humidity data detected by a humidity sensor, temperature data detected by a temperature sensor, etc.
In some embodiments of the present invention, the air conditioner includes a line controller 6 connected to the controller 5; the controller 5 further includes an internal sterilization instruction generation module 53, configured to generate an internal sterilization instruction and send the internal sterilization instruction to the line controller 6 when the set condition is met, and the line controller 6 sends an internal sterilization prompt message after receiving the internal sterilization instruction.
The internal sterilization prompt information is displayed on the display interface of the wired controller 6, or a buzzer sends out a sound prompt, or the internal sterilization prompt information is sent to the user terminal by the wired controller 6 based on networking.
After learning the internal sterilization prompt information, the user can confirm the internal sterilization by triggering the confirmation key or the control of the line controller 6, or send a confirmation internal sterilization instruction to the line controller 6 or directly to the controller 5 through the user terminal.
The line controller 6 or the controller 5 transmits the confirmed internal sterilization command to the internal sterilization module 52 after receiving the confirmed internal sterilization command, and the internal sterilization module 52 performs the internal sterilization of the air conditioner based on the confirmed internal sterilization command.
In some embodiments of the present invention, if the user does not confirm the internal sterilization, that is, after the line controller 6 sends the internal sterilization prompt information, the line controller 6 or the controller 5 does not receive the internal sterilization confirmation instruction fed back by the user, the unconfirmed time t is timed, the line controller 6 sends the calculated unconfirmed time t to the controller 5, and the controller 5 calculates the internal sterilization time TS according to the unconfirmed time t, wherein the longer the unconfirmed time t is, the longer the internal sterilization time TS is.
In some embodiments of the present invention, a maximum sterilization limit tmax is set, when the maximum sterilization limit tmax is not exceeded, the line controller 6 or the controller 5 records an unconfirmed time period t, and the controller 5 calculates an internal sterilization time TS according to the unconfirmed time period t, during which, when the user confirms internal sterilization and the line controller 6 or the controller 5 receives an instruction to confirm internal sterilization, the internal sterilization module 52 performs internal sterilization according to the calculated internal sterilization time period TS.
In other embodiments of the present invention, if the user does not confirm the internal sterilization and the air conditioner is not operating, the internal sterilization module 52 may directly perform the internal sterilization according to the preset time duration and the preset rotation speed of the fan 4, if the air conditioner is operating, the line controller 6 or the controller 5 records the unconfirmed time duration t if the maximum sterilization limit tmax is not exceeded, the controller 5 calculates the internal sterilization time TS according to the unconfirmed time duration t, and during this time, if the current operation program of the air conditioner is finished, the internal sterilization module 52 performs the internal sterilization according to the calculated internal sterilization time duration TS.
If the time exceeds the maximum sterilization limit tmax and the internal sterilization confirmation instruction is always received, the internal sterilization module 52 stops the current air conditioner operation program, and performs internal sterilization according to the maximum sterilization duration TSmax, thereby preventing the air conditioner from affecting the health of the user due to the fact that the internal sterilization is not performed for a long time.
In practical application, the set condition and the longest sterilization time limit tams of the internal sterilization can be adaptively adjusted according to the actual operation mode of the air conditioner, for example, in the case of continuously executing the heating mode in winter, the indoor environment is relatively dry, the set condition and the longest sterilization time limit can be appropriately widened, and in the case of relatively humid indoor environment in spring and summer, the set condition and the longest sterilization time limit are narrowed; when the air conditioner is not operated for a long time, the internal sterilization is started first, and then the operation program set by the user is executed.
Based on the air conditioner proposed above, the sterilization control method of the air conditioner correspondingly proposed in the present invention, as shown in fig. 4, is executed in the air conditioner, and includes the following steps:
step S41: and during the operation of the air conditioner, starting the negative ion generator and controlling the fan to operate in the positive direction.
After the air conditioner is started to operate according to modes such as refrigeration, heating or dehumidification, the fan is controlled to operate in the positive direction, the negative ion generator is started, negative ions generated by the negative ion generator enter a room under the drive of wind, and indoor air is purified and sterilized.
Step S42: and when an internal sterilization instruction is received, the negative ion generator is started to control the fan to run reversely and positively.
When a user initiatively initiates an internal sterilization instruction through a line controller, a remote controller or a user terminal or when the operation of the air conditioner reaches a set condition to generate the internal sterilization instruction, the negative ion generator is started to control the fan to reversely operate, and negative ions generated by the negative ion generator enter the air conditioner under the drive of wind to purify and sterilize the inside of the air conditioner.
The start-up anion generator herein includes the following cases: when the anion generator is currently in the activated state, the activated state is maintained.
The setting condition includes, but is not limited to, reaching a preset time interval, the operating time of the external sterilization module 51 reaching a set time, or the sensor data exceeding a preset value, whichever is reached first.
As shown in fig. 5, when the set condition is reached, step S43: the controller of the air conditioner generates an internal sterilization command, and performs the step S42 or the step S44 according to the internal sterilization command: and sending the generated internal sterilization instruction to the line controller.
And after receiving the internal sterilization instruction, the wire controller sends out internal sterilization prompt information in a display and/or buzzing mode, or sends out the internal sterilization prompt information to the user terminal.
After the user knows the internal sterilization prompt information, the user can choose to confirm the execution of the internal sterilization or disregard the internal sterilization.
When the user uses the line controller or the user terminal to send an internal sterilization command, the process proceeds to step S42, and if the user does not confirm the internal sterilization, the process proceeds to step S45: the unacknowledged duration is calculated.
The wire controller times the unconfirmed time length and sends the unconfirmed time length to the controller of the air conditioner, or the controller of the air conditioner times the unconfirmed time length.
Step S46: the internal sterilization time is calculated based on the unconfirmed time period.
If the user confirms that the internal sterilization is performed when the maximum sterilization limit tmax is not exceeded during the time counting, the routine proceeds to step S47: the internal sterilization is performed according to the calculated internal sterilization time, and if the user does not confirm the execution of the internal sterilization, step S48 may be performed: after the current air conditioner operation program is finished, the process proceeds to step S47 to perform internal sterilization.
If the user does not confirm the time period when the maximum sterilization limit tmax is exceeded, the step S49 is executed: and stopping the current operation program, and forcibly executing internal sterilization according to the longest sterilization time.
Based on the air conditioner and the sterilization control method thereof provided by the invention, on the basis of the existing air conditioner with the negative ion sterilization function, the cost is not increased, the negative ions generated by the negative ion generator are brought into the air conditioner through the reverse rotation of the fan in a mode of changing the running direction of the fan after receiving an internal sterilization instruction, and the sterilization is carried out on the sterilization blind zone in the air conditioner, so that the bidirectional sterilization of the air conditioner is realized based on the logic control of the air conditioner, the internal sterilization prompt information is initiated by a wire controller, the mode of confirming the internal sterilization is provided for a user, and the user can select whether to immediately carry out the internal sterilization within the maximum sterilization limit, so that the current experience effect of the user is not influenced, the internal sterilization is forcibly carried out after the maximum sterilization limit is exceeded, and the health of the user is ensured.
It should be noted that, in a specific implementation process, the air conditioner sterilization control method may be implemented by a processor in a hardware form executing a computer execution instruction in a software form stored in a memory, which is not described herein again, and all programs corresponding to actions executed by the air conditioner may be stored in a computer readable storage medium of a system in a software form, so that the processor calls and executes operations corresponding to the above modules.
