However, in the scheme, only the problem of odor adsorption is considered, and the factor that bacteria propagate to generate odor due to high internal humidity of the air conditioner is not considered, so that the problem of odor cannot be solved from the root.
Moreover, although the indoor air conditioner can heat and dry the inner cavity of the indoor air conditioner in a heating mode of the electric auxiliary heating device, the indoor air conditioner needs to be continuously electrified, heated and dried for the electric auxiliary heating device in order to achieve the effect of keeping low humidity, on one hand, the waste of electric power can be caused, on the other hand, the potential safety hazard exists when the indoor air conditioner is operated for a long time, and the operation of the air conditioner is not facilitated.

The embodiment of the control method of the air-conditioning indoor unit comprises the following steps:
the control method of the air-conditioning indoor unit of the invention is an application program applied to the air-conditioning indoor unit in the above embodiment, and is used for controlling the humidity of the inner cavity 11 of the air-conditioning indoor unit 1.
As shown in fig. 3, in the control method of the indoor unit of an air conditioner according to the present invention, when the indoor unit of an air conditioner is operated, step S1 is first executed, and after entering the idle state, the opening/closing device 23 is controlled to open, and the storage chamber 26 and the inner chamber 11 are communicated to each other for dehumidification. After entering the idle state, in order to avoid that the air conditioner generates water vapor in the inner cavity 11 during the operation states of cooling, heating, blowing, etc., which causes the humidity of the inner cavity 11 to be too high, thereby causing bacteria to grow, the inner cavity 11 needs to be dehumidified by the dehumidifying device 2. At this time, the opening/closing device 23 can be controlled to open, the cavity 26 and the inner cavity 11 are communicated, and the moisture in the inner cavity 11 is adsorbed by the thermal desorption dehumidifying agent 22, so that the inner cavity 11 is kept in a low-humidity state.
In this embodiment, referring to fig. 4, when the opening/closing device 23 is controlled to be opened to communicate the accommodating chamber 26 with the inner chamber 11 for dehumidification, step S11 is first executed to obtain the indoor relative humidity and the relative humidity of the inner chamber 11. When dehumidifying the inner cavity 11 of the air conditioning indoor unit 1, in order to optimize the dehumidification effect, it may be considered to perform humidity control on the inner cavity 11 by using the indoor air, and therefore, it is necessary to acquire the indoor relative humidity and the relative humidity of the inner cavity 11 so as to determine whether humidity control can be performed on the inner cavity 11 by using the indoor air.
After the indoor relative humidity and the relative humidity of the inner cavity 11 are obtained, step S12 is executed, and the opening and closing states of the air inlet and the air outlet of the indoor air conditioning unit 1 are controlled according to the indoor relative humidity and the relative humidity of the inner cavity 11. The opening and closing states of the air inlet and the air outlet of the indoor unit 1 of the air conditioner are controlled according to the indoor relative humidity and the relative humidity of the inner cavity 11, so that the dehumidification effect can be optimized. In this embodiment, controlling the open/close states of the air inlet and the air outlet of the indoor unit 1 according to the indoor relative humidity and the relative humidity of the inner cavity 11 includes: when the relative humidity of the inner cavity 11 is smaller than a first threshold value, closing an air inlet and an air outlet of the indoor unit 1 of the air conditioner; when the relative humidity of the inner cavity 11 is greater than or equal to a first threshold value and the relative humidity of the inner cavity 11 is greater than the indoor relative humidity, opening an air inlet and an air outlet of the indoor unit 1 of the air conditioner; and when the relative humidity of the inner cavity 11 is greater than or equal to the first threshold and the relative humidity of the inner cavity 11 is less than or equal to the indoor relative humidity, closing the air inlet and the air outlet of the indoor unit 1 of the air conditioner. Wherein the first threshold is preset according to experimental data. When the relative humidity of the inner cavity 11 is smaller than the first threshold, it indicates that the humidity of the inner cavity 11 does not need to be adjusted by the external environment, and the air inlet and the air outlet of the indoor unit 1 of the air conditioner are closed. When the relative humidity of the inner cavity 11 is greater than or equal to the first threshold value and the relative humidity of the inner cavity 11 is greater than the indoor relative humidity, it is indicated that the humidity of the inner cavity 11 needs to be adjusted, the inner cavity 11 is communicated with the indoor environment by opening the air inlet and the air outlet of the indoor unit 1 of the air conditioner, the auxiliary thermal desorption desiccant 22 reduces the relative humidity of the inner cavity 11, when the air inlet and the air outlet of the indoor unit 1 of the air conditioner are opened, the fan of the indoor unit can be controlled to run in a low-windshield mode, air circulation is accelerated, and when the indoor relative humidity is close to or equal to the relative humidity of the inner cavity 11, the air inlet and the air outlet of the indoor unit 1 of the air conditioner can be closed. When the relative humidity of the inner cavity 11 is greater than or equal to the first threshold and the relative humidity of the inner cavity 11 is less than or equal to the indoor relative humidity, it indicates that the humidity of the indoor environment is greater than the humidity of the inner cavity 11, and in order to prevent the humidity of the inner cavity 11 from further increasing, the air inlet and the air outlet of the indoor unit 1 of the air conditioner are closed, and only the thermal desorption desiccant 22 is used for dehumidification.
After the opening/closing device 23 is controlled to open and the accommodating chamber 26 and the inner chamber 11 are communicated for dehumidification, step S2 is executed to determine whether to start the self-cleaning mode. After the thermal desorption desiccant 22 adsorbs moisture, thermal desorption operation is required so as to be reusable. If the thermal desorption desiccant 22 is subjected to thermal desorption alone, the energy consumption is high, and a certain air conditioning operation time is required. In the self-cleaning mode, heating is required in the defrosting and drying stages, so that thermal desorption operation can be performed on the thermal desorption desiccant 22 when the self-cleaning mode is started, energy consumption is reduced, and extra thermal desorption time is saved. The self-cleaning mode can be started by a user through sending an instruction by the control terminal, and can be automatically identified by setting a judgment condition for starting the self-cleaning mode.
If the self-cleaning mode is confirmed to be started, step S3 is executed to control the open/close state of the open/close device 23 according to the operation stage of the self-cleaning mode. The self-cleaning mode comprises four operation stages of condensation, frosting, defrosting and drying. The different operating phases require corresponding control of the open and closed state of the opening and closing device 23.
Referring to fig. 5, in the present embodiment, when the open/close state of the opening/closing device 23 is controlled according to the operation stage of the self-cleaning mode, step S31 is performed first, and when the operation stage is in the condensation or frost formation stage, the opening/closing device 23 is closed. When the operation stage of the self-cleaning mode is in the condensation or frosting stage, the opening and closing device 23 is closed, and the phenomenon that water vapor generated in the condensation or frosting stage is adsorbed by the thermal desorption dehumidifying agent 22 to cause over-fast adsorption saturation is avoided.
Next, step S32 is executed, when the operation phase is in the defrosting or drying phase, the opening and closing device 23 is opened, and the thermal desorption operation is performed on the thermal desorption desiccant 22. The defrosting and drying stages need to be heated, the opening and closing device 23 is opened, and the heating in the defrosting or drying stage is utilized to carry out thermal desorption operation on the thermal desorption desiccant 22, so that the energy consumption is reduced, and the additional thermal desorption time is saved.
In this embodiment, the step of performing the thermal desorption operation on the thermal desorption desiccant 22 further includes: the heating device 24 is activated to heat. In the defrosting and drying stages, the thermal desorption operation can be performed by utilizing the air conditioner for heating, and the heating device 24 can be started for heating, so that the heating speed is further increased, and the thermal desorption operation process is accelerated.
In this embodiment, the step of performing the thermal desorption operation on the thermal desorption desiccant 22 further includes: and starting an exhaust air draft device 26 for air draft. In order to avoid the volatile gas of thermal desorption operation to stay indoor, carry out convulsions through outer updraft ventilator 26 of arranging, can take out moisture, peculiar smell, harmful gas etc. that the thermal desorption operation produced outdoor, avoid influencing user experience.
Finally, step S33 is executed to open the opening and closing device 23 when the self-cleaning mode is exited. When exiting the self-cleaning mode, the opening and closing device 23 needs to be opened, the inner cavity 11 of the indoor unit 1 of the air conditioner is kept at a low humidity by the thermal desorption desiccant 22, and peculiar smell and harmful gas can be adsorbed.
As can be seen from fig. 1, after the step S2 is executed, if it is determined that the self-cleaning mode is not activated, the step S4 is executed to determine whether the thermal desorption desiccant 22 is saturated. In order to avoid that the inner cavity 11 of the air-conditioning indoor unit 1 has too high humidity due to the fact that the thermal desorption desiccant 22 cannot continuously adsorb after absorbing water vapor to saturation, the absorption rate detection device 25 is arranged to detect the adsorption state of the thermal desorption desiccant 22 so as to judge whether thermal desorption operation is needed.
If it is confirmed that the thermal desorption desiccant 22 is not in the saturated state, the process returns to step S2 to perform the continuous detection. If it is determined that the thermal desorption desiccant 22 is saturated, step S5 is performed, the opening/closing device 23 is closed, the exhaust ventilator 26 is opened, and the heating device 24 is started to perform the thermal desorption operation. But when thermal desorption desiccant 22 reaches the saturation state, close switching device 23, open outer exhaust updraft ventilator 26 and start heating device 24 and carry out the thermal desorption operation, but so that reuse thermal desorption desiccant 22, and simultaneously, close switching device 23 and carry out the thermal desorption operation, make the inner chamber 11 of chamber 26 and the air conditioning indoor set 1 that holds of dehydrating unit 2 keep apart, avoid the steam that the thermal desorption operation produced, the peculiar smell gets into the inner chamber 11 of air conditioning indoor set 1, and through outer exhaust updraft ventilator 26 with the steam that the thermal desorption operation produced, the peculiar smell discharges to outdoors.
After the thermal desorption operation is performed, step S6 is performed, and after the thermal desorption operation is completed, the opening and closing device 23 is opened, and the exhaust ventilator 26 and the heating device 24 are closed. When the thermal desorption operation is performed, the temperature is heated to the preset temperature and is continuously kept for the preset time, so that the thermal desorption desiccant 22 can be fully thermally desorbed, after the thermal desorption operation is completed, the opening and closing device 23 is opened, the inner cavity 11 of the indoor unit 1 of the air conditioner is kept at a low humidity by using the thermal desorption desiccant 22, and the growth of bacteria is inhibited.
It should be noted that, in practical applications, the execution order of step S2 and step S4 may be interchanged.
As can be seen from the above, in the control method of the indoor unit of an air conditioner according to the present invention, the dehumidifying device 2 having the thermal desorption dehumidifying agent 22 is disposed inside the indoor unit of an air conditioner 1, and when the indoor unit enters the idle state, the opening and closing device 23 is controlled to open, so as to communicate the accommodating chamber 26 with the inner chamber 11 for dehumidification, thereby ensuring a low humidity inside the air conditioner and suppressing the generation of bacteria from the source. Meanwhile, when the self-cleaning mode is started, the thermal desorption operation is performed on the thermal desorption desiccant 22 by using the heating in the defrosting and drying stages, so that the energy consumption is reduced, the extra thermal desorption time is saved, and the operation of the air conditioner is facilitated.
