Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present invention has been described with reference to an indoor unit of an air conditioner, since the indoor unit and the outdoor unit of the air conditioner have a symmetrical structure, the principle of the present invention is also applicable to the self-cleaning of the outdoor unit during the heating operation of the air conditioner, and at this time, the fan current of the indoor unit is replaced by the fan current of the outdoor unit and the coil temperature of the indoor unit is replaced by the coil temperature of the outdoor unit.
Based on the problem that the existing air conditioner cannot execute different self-cleaning modes according to judgment conditions pointed out by the background art, the invention provides a self-cleaning control method for the air conditioner and the air conditioner, aiming at enabling the air conditioner to select the optimal self-cleaning mode according to the self-dust-deposition degree no matter the air conditioner generates condensation or does not generate condensation, enabling the self-cleaning operation of the air conditioner to be more intelligent, and simultaneously avoiding the situations of excessive energy waste and poor cleaning effect of the air conditioner.
Specifically, the air conditioner of the present invention includes an indoor unit, and as shown in fig. 1, the self-cleaning control method of the present invention includes: when the air conditioner operates in a refrigerating mode, acquiring fan current of an indoor unit, coil temperature of the indoor unit and dew point temperature of air; comparing the difference value between the coil temperature of the indoor unit and the standard coil temperature with a preset temperature value; if the difference value between the coil temperature of the indoor unit and the standard coil temperature is greater than the preset temperature value, comparing the coil temperature of the indoor unit with the dew point temperature of air; and executing a corresponding self-cleaning mode on the indoor unit according to the comparison result of the temperature of the coil pipe of the indoor unit and the dew point temperature of the air and the fan current of the indoor unit. The preset temperature value may be 2 ℃, which is not restrictive, and a person skilled in the art may flexibly set a specific value of the preset temperature value in practical application, as long as whether the coil temperature of the indoor unit is too high can be determined by the demarcation point determined by the preset temperature value. It should be noted that the current of the fan of the indoor unit can directly reflect the dust deposition degree of the air conditioner, because the load of the fan is determined at a certain rotation speed, when the load of the fan is increased at the same rotation speed, and accordingly, the current of the fan is decreased, it is indicated that the wind resistance of the fan is increased, that is, the dust deposition on the indoor unit is performed, and the more serious the dust deposition is, the smaller the current of the fan is, so the dust deposition degree of the indoor unit of the air conditioner can be fully determined according to the current of the fan. In addition, the coil temperature of the indoor unit can be acquired through an indoor unit coil temperature sensor, and the dew point temperature of air can be acquired through an air dew point temperature sensor.
In practical application, fan currents of the indoor unit under different condensation degrees with condensation and without condensation on the indoor unit can be measured in an experimental mode before the air conditioner leaves a factory, namely the air conditioner is enabled to run in a refrigerating mode under the condition that the air conditioner is completely clean and generates condensation, and a first preset current value is measured; enabling the air conditioner to run in a refrigerating mode under the condition that the air conditioner is slightly dusted and generates condensation, and measuring a second preset current value; enabling the air conditioner to run in a refrigerating mode under the condition that the air conditioner is heavily dusted and generates condensation, and measuring a third preset current value; enabling the air conditioner to run in a refrigerating mode under the condition that the air conditioner is completely clean and condensation is not generated, and measuring a fourth preset current value; enabling the air conditioner to run in a refrigerating mode under the condition that the air conditioner is slightly dusty and does not generate condensation, and measuring a fifth preset current value; and (4) enabling the air conditioner to run in a refrigerating mode under the condition that the air conditioner is heavily dusted and condensation is not generated, and measuring a sixth preset current value. The skilled person can flexibly set the ash deposition degree of the air conditioner according to the actual situation, for example, the separation can be performed according to the thickness of the ash layer on the air conditioner, the slight ash deposition of the air conditioner is set when the thickness of the ash layer is 0.5-1 mm, the moderate ash deposition of the air conditioner is set when the thickness of the ash layer is 1-2 mm, the serious ash deposition of the air conditioner is set when the thickness of the ash layer is more than 2 mm or an ash net is formed, by such a setting mode, the fan current correspondingly measured in each situation can be divided into sections, that is, under the condition that the condensation is generated in the indoor unit of the air conditioner, if the fan current of the indoor unit is equal to the first preset current value, the air conditioner is not deposited with ash, and the air conditioner does not need to perform self-; if the current of the fan of the indoor unit is smaller than a first preset current value and larger than a second preset current value, the air conditioner is slightly dusted; if the current of the fan of the indoor unit is smaller than the second preset current value and larger than the third preset current value, indicating that the air conditioner is moderately dusted; if the fan current of the indoor unit is smaller than a third preset current value, the air conditioner is seriously grayed, wherein the first preset current value is larger than a second preset current value which is larger than the third preset current value; under the condition that condensation is not generated in the indoor unit of the air conditioner, if the fan current of the indoor unit is equal to a fourth preset current value, the air conditioner is not dusted, and the air conditioner does not need to perform self-cleaning; if the fan current of the indoor unit is smaller than the fourth preset current value and larger than the fifth preset current value, the air conditioner is slightly dusted; if the current of the fan of the indoor unit is smaller than a fifth preset current value and larger than a sixth preset current value, indicating moderate dust formation of the air conditioner; if the fan current of the indoor unit is smaller than a sixth preset current value, the air conditioner is seriously grayed, wherein the fourth preset current value is larger than a fifth preset current value, and the fifth preset current value is larger than the sixth preset current value. In addition, since the water vapor in the air may be pre-cooled on the indoor unit to generate condensation when the coil temperature of the indoor unit is less than the dew point temperature of the air, and the fan current of the indoor unit of the air conditioner may be reduced to some extent due to the condensation, the first preset current value may be set to be lower than the fourth preset current value, specifically, the first preset current value may be set to be equal to or equal to 0.9 times of the fourth preset current value, the second preset current value may be set to be equal to or less than the fifth preset current value, and the third preset current value may be set to be equal to or less than the sixth preset current value. A person skilled in the art can flexibly set specific values of the first preset current value, the second preset current value, the third preset current value, the fourth preset current value, the fifth preset current value and the sixth preset current value in practical application, as long as the ash formation degree of the air conditioner can be distinguished through a boundary point determined by the first preset current value, the second preset current value, the third preset current value, the fourth preset current value, the fifth preset current value and the sixth preset current value, so that the air conditioner can select an optimal self-cleaning mode. In addition, in the embodiment of the present invention, the standard coil temperature may be measured before the air conditioner leaves the factory, that is, the air conditioner is in a completely clean state, so that the air conditioner operates under a standard working condition, and during the operation of the air conditioner under the standard working condition, the standard coil temperatures respectively corresponding to the fans of the indoor unit at different rotation speeds are measured.
