Referring to fig. 1, an embodiment of the present disclosure provides a control method for self-cleaning of an air conditioner, including the following steps:
s101: and after receiving the self-cleaning instruction of the air conditioner, controlling the air conditioner to execute self-cleaning operation and enter a self-cleaning frost-condensation stage.
A user can send a self-cleaning instruction to the air conditioner through a remote controller and the like according to actual requirements. And after receiving the self-cleaning instruction of the air conditioner, the air conditioner is controlled to execute self-cleaning operation and enters a self-cleaning and frost-condensing stage. When the indoor heat exchanger of the air conditioner is self-cleaned, the four-way valve of the air conditioner is adjusted, the indoor heat exchanger of the air conditioner is controlled to enter a frost condensation stage, the air conditioner runs in a refrigeration mode, moisture in indoor air is condensed on the surface of the heat exchanger of the indoor machine in a bead form, the air conditioner condenses on the surface of the heat exchanger in the later stage of frost condensation to form a frost layer through a mode of improving refrigerating capacity, and the frost layer is combined with dust on the surface of the heat exchanger. When the outdoor heat exchanger of the air conditioner is self-cleaned, the four-way valve of the air conditioner is adjusted, the outdoor heat exchanger of the air conditioner is controlled to enter a frost condensation stage, the air conditioner runs in a heating mode, moisture in outdoor air is condensed on the surface of the outdoor heat exchanger in a bead form, the air conditioner in the later stage of frost condensation enables the beads condensed on the surface of the heat exchanger in the earlier stage to be condensed into a frost layer in a mode of improving heating capacity, and the frost layer is combined with dust on the surface of the heat exchanger.
S102: and under the condition of frost on the surface of the heat exchanger, controlling the ultrasonic oscillator to vibrate according to a preset vibration frequency so as to vibrate and drop the frost on the surface of the heat exchanger.
The heat exchanger of air conditioner is provided with ultrasonic oscillator, produces ultrasonic vibration through ultrasonic oscillator, makes the frost vibration on heat exchanger surface drop to make the frost that adsorbs the dust clear up in time, realize the defrosting function of traditional air conditioner automatically cleaning defrosting stage.
By adopting the control method for self-cleaning of the air conditioner, after the self-cleaning instruction of the air conditioner is received, the air conditioner is controlled to execute the self-cleaning operation and enter the self-cleaning frost condensation stage, and the ultrasonic oscillator is controlled to vibrate according to the preset vibration frequency to vibrate the frost condensation on the surface of the heat exchanger to fall off under the condition of the frost condensation on the surface of the heat exchanger. Like this, at air conditioner automatically cleaning in-process, the frost vibration that produces the heat exchanger surface in the frost stage through the ultrasonic wave mode drops, need not to realize changing the frost through the operational mode who changes the air conditioner, can effectively shorten the whole time of air conditioner automatically cleaning operation to promote user experience better.
In some embodiments, the control method for air conditioner self-cleaning further includes: controlling an ultrasonic oscillator to vibrate according to a preset vibration frequency, and obtaining the operating frequency of a compressor of the air conditioner in a self-cleaning frost-condensation stage; and determining the vibration frequency corresponding to the running frequency as a preset vibration frequency.
Optionally, obtaining an operating frequency of a compressor of the air conditioner in a self-cleaning frost-condensation stage includes: determining the operating frequency as a first operating frequency under the condition that the indoor environment temperature is greater than or equal to a first preset temperature and the outdoor environment temperature is greater than or equal to a second preset temperature; determining the operating frequency to be a second operating frequency under the condition that the indoor environment temperature is less than a first preset temperature and the outdoor environment temperature is less than a second preset temperature; the first preset temperature is less than or equal to the second preset temperature, and the first operating frequency is less than the second operating frequency.
Here, the first predetermined temperature is in the range of [10 deg.C, 18 deg.C ], e.g., 10 deg.C, 15 deg.C, 18 deg.C; the second predetermined temperature is in the range of [13 deg.C, 20 deg.C ], e.g., 13 deg.C, 15 deg.C, 18 deg.C, 20 deg.C.
In practical application, a corresponding relation table of the operating frequency of the compressor and the vibration frequency of the ultrasonic oscillator is established. In the correspondence table, the vibration frequency of the ultrasonic oscillator is positively correlated with the operating frequency of the compressor, that is, the high vibration frequency of the ultrasonic oscillator corresponds to the high operating frequency of the compressor, and the low vibration frequency of the ultrasonic oscillator corresponds to the low operating frequency of the compressor. After the operating frequency of the compressor is determined, the vibration frequency of the ultrasonic oscillator can be determined by searching the corresponding relation table.
In general, the higher the ambient temperature, the greater the ambient humidity. Under the condition that the indoor environment temperature is greater than or equal to a first preset temperature and the outdoor environment temperature is greater than or equal to a second preset temperature, the environment humidity on the surface of the heat exchanger is high, the compressor is controlled to operate according to a first operation frequency (relatively low operation frequency), the frost condensation time of the air conditioner is properly prolonged, moisture in indoor air is fully condensed into a frost layer on the surface of the heat exchanger, the effect of dust adsorption of frost is improved, and the self-cleaning effect of the air conditioner is improved; under the condition that the indoor environment temperature is lower than the first preset temperature and the outdoor environment temperature is lower than the second preset temperature, the environment humidity on the surface of the heat exchanger is lower, the compressor is controlled to operate according to the second operation frequency (relatively higher operation frequency), so that moisture in the indoor air is quickly condensed into a frost layer on the surface of the heat exchanger, the moisture around the heat exchanger is fully utilized, the effect of dust adsorption by frost is improved, and the self-cleaning effect of the air conditioner is improved.
In some embodiments, the control method for air conditioner self-cleaning further includes: after the air conditioner is controlled to finish one-time self-cleaning operation, under the condition that the air conditioner stably runs, the ambient temperature between the heat exchanger and a fan of the air conditioner is obtained; and controlling the air conditioner to execute secondary self-cleaning operation according to the proportional relation between the ambient temperature and the preset temperature.
In practical application, when the environmental temperature between the heat exchanger and the fan is used for judging the dust accumulation degree of the heat exchanger, only the environmental temperature obtained when the air conditioner operates stably is judged, and the operation mode when the air conditioner operates stably can be a high-wind-gear refrigeration operation mode, a medium-wind-gear refrigeration operation mode or a low-wind-gear refrigeration operation mode. Since the ambient temperature between the heat exchanger and the fan of the air conditioner is greatly affected by the external environment when the air conditioner is in unstable operation (for example, the air conditioner is in a frequency release state), the ambient temperature at this time cannot accurately reflect the dust accumulation degree of the heat exchanger.
Optionally, the heat exchanger comprises an indoor heat exchanger, and the fan comprises a cross-flow fan arranged in the indoor unit of the air conditioner; obtaining an ambient temperature between a heat exchanger and a fan of an air conditioner, comprising: obtaining a first ambient temperature of a first temperature detection point between the indoor heat exchanger and the cross-flow fan; the first temperature detection point is located in the middle of the casing of the cross-flow fan and is located in the middle between the casing of the cross-flow fan and the indoor heat exchanger; the first ambient temperature is determined to be the ambient temperature.
Considering that the temperature at the air outlet of the cross flow fan is easily influenced by the external environment temperature, the temperature between aluminum foils of the indoor heat exchanger cannot accurately reflect the integral dust accumulation degree of the indoor heat exchanger, the air volume at the casing of the cross flow fan is small, and the influence of blowing on the temperature at the casing is small, so that the first temperature detection point is arranged at the middle position of the casing of the cross flow fan and the middle position between the casing of the cross flow fan and the indoor heat exchanger, and the detected environment temperature is not easily influenced by the external environment and can more accurately reflect the integral dust accumulation degree of the indoor heat exchanger.
Optionally, the heat exchanger comprises an outdoor heat exchanger, and the fan comprises an axial flow fan arranged on the outdoor unit of the air conditioner; obtaining an ambient temperature between a heat exchanger and a fan of an air conditioner, comprising: obtaining a second ambient temperature of a second temperature detection point between the outdoor heat exchanger and the axial flow fan; the second temperature detection point is positioned on the surface of a fin of the outdoor heat exchanger; obtaining a third ambient temperature of a third temperature detection point between the outdoor heat exchanger and the axial flow fan; the third temperature detection point is positioned at the rotating shaft of the axial flow fan; obtaining a fourth ambient temperature of a fourth temperature detection point between the outdoor heat exchanger and the axial flow fan; the fourth temperature detection point is positioned in the middle between the surface of the fin of the outdoor heat exchanger and the rotating shaft of the axial flow fan; calculating to obtain the weighted environment temperature of the second environment temperature, the third environment temperature and the fourth environment temperature; determining the weighted ambient temperature as the ambient temperature.
Because the ambient temperature between the outdoor heat exchanger of the air conditioner and the fan is greatly influenced by the external environment, a plurality of temperature detection points are selected, and the temperature between the outdoor heat exchanger and the axial flow fan is comprehensively determined according to the temperatures detected by the temperature detection points. Considering that most dust accumulation points of the outdoor heat exchanger are accumulated in the fins, the air volume at the rotating shaft of the axial flow fan is small, and the influence of blowing air on the temperature at the rotating shaft is small, therefore, the three temperature detection points are respectively arranged on the surfaces of the fins of the outdoor heat exchanger, the rotating shaft of the axial flow fan and the middle position between the surfaces of the fins of the outdoor heat exchanger and the rotating shaft of the axial flow fan, so that the three temperature detection points are used for detecting and obtaining the weight environment temperature, the weight environment temperature is directly controlled by the dust accumulation degree of the outdoor heat exchanger, and the dust accumulation degree of the whole outdoor heat exchanger can be more accurately reflected.
Optionally, calculating the weighted ambient temperature of the second ambient temperature, the third ambient temperature, and the fourth ambient temperature includes:
wherein T is the weight ambient temperature,
is a second ambient temperature weight coefficient, T2Is the temperature of the second environment, and,
is a third ambient temperature weight coefficient, T3Is the temperature of the third environment, and,
is the fourth ambient temperature weight coefficient, T4Is the fourth ambient temperature.
In the practical application of the method, the material is,
and is
The temperature of the middle position between the surface of the fin of the outdoor heat exchanger and the rotating shaft of the axial flow fan can accurately reflect the dust accumulation degree of the outdoor heat exchanger, the temperature fluctuation range is relatively small, and the temperature value is relatively stable; the air quantity at the rotating shaft of the axial flow fan is minimum, the influence of blowing is minimum, and the temperature value is most stable; and the temperature at the surface of the fins of the outdoor heat exchanger can reflect the degree of dust accumulation of the outdoor heat exchanger. Therefore, the weighting coefficients of the second environment temperature, the third environment temperature and the fourth environment temperature are set according to the mode, and the outdoor heat exchanger can be more accurately reflected by calculating and obtaining the weighting environment temperatureOverall dust accumulation.
Optionally, controlling the air conditioner to perform a secondary self-cleaning operation according to a proportional relationship between the ambient temperature and a preset temperature, including: calculating the ratio of the ambient temperature to the preset temperature; controlling the air conditioner to execute secondary self-cleaning operation under the condition that the ratio is in a first preset ratio range; and controlling the air conditioner to finish the self-cleaning operation under the condition that the ratio is in a second preset ratio range.
The preset temperature may be a temperature between the heat exchanger and the fan detected under the same stable operation condition after the heat exchanger of the air conditioner completes one self-cleaning, for example, a temperature between the heat exchanger and the fan detected by the air conditioner in a high-wind-gear cooling operation mode, a medium-wind-gear cooling operation mode or a low-wind-gear cooling operation mode. The first preset ratio range may be [0, 80% ], for example, 0, 20%, 30%, 40%, 50%, 80%, and the second preset ratio range may be (80%, 100% ], for example, 80%, 90%, 100%. when the ratio of the ambient temperature to the preset temperature is in the first preset ratio range, it indicates that there is an excessive accumulation of dust on the heat exchanger, the second self-cleaning operation is immediately performed to avoid a large influence on the normal heat exchange of the air conditioner and the life health of the user, and when the ratio of the ambient temperature to the preset temperature is in the second preset ratio range, it indicates that there is no dust accumulation in the heat exchanger, the self-cleaning operation is thorough, and the air conditioner is controlled to finish the self-cleaning operation.
