In one embodiment of the present disclosure, referring to fig. 2 and 3, the humidifying device, the decontaminating device and the flavoring device each include a nozzle 40, a conduit 50 and a storage device, wherein one end of each conduit 50 is connected to the nozzle 40, and the other end is connected to the storage device; the partition 30 includes an upper bracket 31 and a lower bracket 32, each nozzle 40 is disposed on the upper bracket 31 or the lower bracket 32, a bracket slot 33 is formed on the lower bracket 32, the guide pipe 50 is disposed in the bracket slot 33, and the storage device is disposed around the partition 30.
The guide tube 50 may be completely disposed in the bracket groove 33, or partially disposed in the bracket groove 33, and partially fixed to the upper bracket 31 or the lower bracket 32, so that the guide tube 50 is not easily dropped, and is effectively connected to the nozzle 40 and the storage device.
It can be understood that the storage device of the humidifying device stores humidifying agent, the storage device of the decontaminating device stores decontaminating agent, and the storage device of the flavoring device stores flavoring agent, and the three devices can be placed at any position in the air conditioner.
In this embodiment, the nozzles 40 and ducts 50 of the humidifying, decontaminating and fragrancing devices are arranged on the support of the partition 30, providing a good support thereof, while facilitating the ejection of the humidifying, decontaminating and fragrancing agents towards the fins of the evaporator 10.
In one embodiment of the present disclosure, the number of the nozzles 40 of the humidifying device, the decontaminating device and the flavoring device is one or more. When the number of the nozzles 40 is plural, they are uniformly distributed on the upper holder 31 and the lower holder 32.
In the present embodiment, when a plurality of nozzles 40 are provided, the amount of the humidifying agent, the decontaminating agent or the odorizing agent sprayed onto the fins of the evaporator 10 can be increased, thereby improving the self-cleaning efficiency and the user's feeling of use.
Referring to fig. 4, fig. 4 is a schematic flow chart of a self-cleaning method according to an embodiment of the present disclosure, the method is applied to an air conditioner, the air conditioner includes an air conditioner indoor unit shown in fig. 1, and the self-cleaning method includes:
s101, responding to the operation that a user starts a self-cleaning mode, and starting a refrigeration mode of the air conditioner;
s102, detecting the temperature of an inner coil of the air conditioner indoor unit;
s103, when the temperature of the inner coil is within a first preset temperature range, starting a nozzle of a humidifying device, and continuously spraying the fins of an evaporator in the air conditioner inner machine within a first preset time period;
step S102 is executed again;
s104, when the temperature of the inner coil is within a second preset temperature range, adjusting the frequency of the compressor to keep the temperature of the inner coil within the second preset temperature range within a second preset time period;
and S105, starting a heating mode of the air conditioner.
In step S101, the operation of the user starting the self-cleaning mode may be to start the self-cleaning mode of the air conditioner by triggering a corresponding physical key on the remote controller or the control panel of the air conditioner, or may be to start the self-cleaning mode of the air conditioner by touching a corresponding virtual key in an air conditioner control program built in the terminal.
Alternatively, the self-cleaning mode may be initiated only in the air conditioner off mode. Taking the self-cleaning mode of the air conditioner started by triggering the corresponding physical key on the remote controller of the air conditioner as an example, in the hot-line shutdown mode of the air conditioner, the key is pressed once to start the self-cleaning mode, and the self-cleaning mode is stopped by pressing once again, and when the key is pressed once again, the self-cleaning mode is restarted.
More, after the air conditioner is powered off, the self-cleaning mode can be directly quitted, and after the air conditioner is powered on again, the air conditioner is in a standby state and is not started.
Furthermore, when the air conditioner enters the self-cleaning mode operation mode, it is not effective to perform other operations, such as a cooling mode, a heating mode, and the like.
In step S103, the first preset temperature range refers to a temperature range suitable for spraying before frosting in the cooling mode, and is usually-8 to 10 degrees celsius (° c), and the first preset time period is 4 to 6 seconds (S). When frosting, the temperature reaches the first preset temperature range firstly, and spray humidification is carried out at the time, so that the frosting amount can be increased.
In step S104, the second preset temperature range is an empirical temperature range in which frosting can occur in the refrigeration mode, the second preset temperature range is about-15 ℃, the second preset time period is a time period in which frosting can occur effectively, and the second preset time period is about 3-5 minutes. Namely, after the spraying humidification is carried out, the air conditioner continues to cool, and the temperature reaches the second preset temperature range again, so that the water mist on the evaporator fins is frosted.
After the spraying is finished, the frosting process is not directly carried out, but the step S102 is carried out again, so that the phenomenon that the frosting effect is poor because the frosting is carried out when the temperature of the inner coil pipe does not reach the second preset temperature range can be prevented.
In this embodiment, in response to a user starting an operation of the self-cleaning mode, a cooling mode of the air conditioner is started, a temperature of an inner coil of an indoor unit of the air conditioner is detected, when the temperature of the inner coil is within a first preset temperature range, a nozzle of a humidifying device is started, fins of an evaporator in the indoor unit of the air conditioner are continuously sprayed within a first preset time period, and the step of detecting the temperature of the inner coil of the indoor unit of the air conditioner is executed again. The defrosting and decontaminating capability of the air conditioner can be effectively improved.
In one embodiment of the present disclosure, before the cooling mode of the air conditioner is started in step S101, the method includes: opening an air deflector of an air conditioner indoor unit; operating the inner motor at a preset rotating speed within a third preset time length; and executing the step of starting the cooling mode of the air conditioner after the internal motor stops running.
Optionally, the air deflector can be opened and then turned to the maximum air outlet angle, then the inner motor is started, the inner motor is rotated to the highest rotation speed in the refrigeration mode, and whether the air deflector and the inner motor are abnormal or not is detected. If the air deflector or the inner motor is abnormal, the fault is prompted to occur, at the moment, a corresponding fault code is displayed for a user, and the cleaning function is quitted. If the air deflector or the inner motor is not abnormal, the step of operating the inner motor at the preset rotating speed within the third preset time is executed, so that the heat in the air conditioner is dissipated, and the heat accumulation of the inner motor is avoided.
The preset rotating speed refers to the rotating speed of the air conditioner in the weak wind mode, and exemplarily, the rotating speed in the weak wind mode is 300-400 rpm, and the third preset time is about 1 minute. Understandably, after the third preset time period is finished, the operation of the inner motor is stopped.
In one embodiment of the present disclosure, during the cooling mode, a process of increasing the frequency of the compressor from 0 to a preset frequency is set as a fast frequency increasing stage, and a process of increasing the frequency of the compressor from the preset frequency to a cooling maximum frequency is set as a slow frequency increasing stage; in the fast frequency increasing stage, increasing to the preset frequency according to a first preset speed; operating the compressor at the preset frequency for a fourth preset time period; in the slow frequency increasing stage, the frequency is increased from the preset frequency to the highest refrigerating frequency at a second preset speed.
In the above process, schematically, 0-46 hertz (Hz) is set as the fast up-conversion stage, the first preset speed is 2 hertz per second (Hz/S), the fourth preset duration is 1 minute, and the 46Hz — refrigeration maximum frequency is set as the slow up-conversion stage. After the frequency of the compressor was increased from 0 to 46Hz at a rate of 2Hz/S, the compressor stayed at 46Hz for 1 minute and then increased from 46Hz to the maximum frequency of the cooling operation at a rate of 1 Hz/S.
In the embodiment, the temperature of the inner machine evaporator is reduced too fast by controlling the frequency-increasing running speed of the compressor in the frosting stage, and the frosting and icing speed on the fins of the inner machine evaporator is too fast, so that the expansion abnormal sound is too large.
In one embodiment of the present disclosure, in the process of executing step S105, the nozzle of the decontamination device is activated, and the decontamination agent is continuously sprayed to the fins of the evaporator in the air conditioner for a fifth preset time period.
Optionally, before step S105, the method includes: and after the second preset time length is finished, stopping running the compressor, adjusting the air deflector to the maximum air outlet angle, starting the inner motor and running to the highest rotating speed in the heating mode, and keeping the running time of the highest rotating speed to be about 2 minutes.
Wherein, for example, the fifth preset time period is in the range of 2 to 4 seconds.
Further, after the detergent is continuously sprayed to the fins of the evaporator in the air conditioner within the fifth preset time period, the method further comprises the following steps: and starting a nozzle of the humidifying device, and continuously spraying the fins of the evaporator in the air conditioner within a sixth preset time. Therefore, the decontaminating agent sprayed by the nozzle of the decontaminating device can be mixed by the water mist sprayed by the nozzle of the humidifying device, and the decontaminating effect on the fins is further enhanced
Wherein, for example, the sixth preset time period is in the range of 30 to 40 seconds.
In one embodiment of the present disclosure, after step S105, the method further includes:
when the heating mode operation of the air conditioner is finished, the step of detecting the temperature of the inner coil of the air conditioner indoor unit is executed again; and when the temperature of the inner coil is within a third preset temperature range, starting a nozzle of the flavoring device, and continuously spraying a flavoring agent to fins of an evaporator in the air conditioner inner unit within a seventh preset time period.
Optionally, step S105 includes: and (3) turning the air conditioner to a heating mode, closing an air deflector of an air conditioner indoor unit, stopping the operation of a motor of the air conditioner indoor unit, starting the operation of the compressor, keeping the temperature of the inner coil pipe at 45 ℃ as an upper limit, prohibiting the frequency of the compressor from rising, and maintaining for 4-6 minutes.
Wherein, for example, the seventh preset time period is 1-2s, the third preset temperature range is the sum of the ambient temperature and a deviation value range, for example, 3-5 ℃, the ambient temperature is 25 ℃, and the third preset temperature range is 28-30 ℃.
In this embodiment, to avoid the short-of-temperature condition, the operation enters the self-cleaning mode again. Meanwhile, the over-high temperature of the evaporator is avoided, and the flavoring agent is volatilized quickly. The odorant nozzle may be turned on after the temperature of the inner coil is lowered to a third predetermined temperature range.
The embodiment of the application also provides an air conditioner, which comprises the air conditioner indoor unit shown in the figure 1.
