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.
The prior air conditioner pointed out based on the background technology cannot enable a user to accurately judge when the air conditioner needs to be cleaned by adopting manual cleaning, so that the air conditioner cannot be cleaned in time, and the air conditioner is easy to have the problem of frequent self-cleaning due to misjudgment in a mode that the air conditioner judges whether to execute self-cleaning according to the current value of a fan of an indoor unit. The invention provides a control method for an air conditioner and the air conditioner, and aims to prompt a user to clean the air conditioner when the air conditioner needs to be cleaned, so that the air conditioner can be cleaned in time, and the user experience is improved.
Specifically, the air conditioner of the present invention includes an indoor unit, and as shown in fig. 1, the control method of the present invention includes: acquiring a fan voltage value of an indoor unit; and selectively prompting that the air conditioner needs to be cleaned according to the voltage value of the fan. It should be noted that the voltage 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 voltage 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 increased, and the more serious the dust deposition is, the smaller the voltage of the fan is, so the dust deposition degree of the indoor unit of the air conditioner can be fully judged according to the voltage of the fan. The technical solution of the present invention is described in detail below with reference to specific examples.
Preferably, as shown in fig. 2, the step of "selectively prompting that the air conditioner needs to be cleaned according to the fan voltage value" specifically includes: calculating the variation value of the fan voltage value relative to the standard voltage value; comparing the variation value with a preset value; and selectively prompting that the air conditioner needs to be cleaned according to the comparison result. Further, the step of selectively prompting that the air conditioner needs to be cleaned according to the comparison result comprises: if the variation value is larger than the preset value, prompting that the air conditioner needs to be cleaned; if the variation value is not greater than the preset value, the air conditioner is not prompted to be cleaned. Specifically, the above-mentioned variation value is equal to the difference Δ U between the standard voltage value Ub and the fan voltage value Uf. That is, if the difference Δ U between the standard voltage value Ub and the fan voltage value Uf is greater than the preset value, it is suggested that the air conditioner needs to be cleaned, and if the difference Δ U between the standard voltage value Ub and the fan voltage value Uf is not greater than the preset value, it is not suggested that the air conditioner needs to be cleaned. In a possible implementation manner, the preset value is set to 0.01V, that is, if Δ U is greater than 0.01V, it indicates that the indoor unit is relatively severely clogged at this time, and it is necessary to prompt a user to clean the air conditioner, and if Δ U is less than or equal to 0.01V, it indicates that the indoor unit is not clogged at this time or the clogging of the indoor unit is still within an acceptable range, and at this time, the user may not be prompted to clean the air conditioner temporarily. Of course, the preset value is not limited to 0.01V in the above example, and those skilled in the art can flexibly set the specific value of the preset value in practical application as long as the demarcation point determined by the preset value can determine whether the air conditioner needs to be cleaned.
Further preferably, the step of "prompting that the air conditioner needs to be cleaned" includes: the indicator light on the indoor unit is changed into the early warning color, wherein the indicator light on the indoor unit can be changed into red or yellow to prompt the user that the air conditioner needs to be cleaned, the specific color of the indicator light can be flexibly set by technicians in the field in practical application as long as the user can be prompted to clean the air conditioner through the selection of the color, of course, the user can be prompted to clean the air conditioner through the sound device (such as a buzzer, a voice broadcaster and the like) on the indoor unit in practical application, or the user is prompted to clean the air conditioner through the combination of the indicator light and the voice device, the technicians in the field can flexibly set the specific prompting mode for the user to clean the air conditioner in practical application, and the adjustment and the change of the prompting mode do not deviate from the principle and the scope of the invention, are intended to be within the scope of the present invention.
Further, the air conditioner of the present invention further includes a controller configured to be able to perform the control method described above. The controller can help a user accurately judge whether the air conditioner needs to be cleaned or not, and can prompt the user when the air conditioner needs to be cleaned, so that the air conditioner can be cleaned in time.
It should be noted that when the user is prompted that the air conditioner needs to be cleaned, the indoor unit of the air conditioner can be cleaned independently, or the indoor unit and the outdoor unit of the air conditioner can be cleaned simultaneously, because when the indoor unit is dirty and blocked, the time limit when the outdoor unit is dirty and blocked can be indirectly fed back to some extent. In addition, in the invention, the specific cleaning mode of the air conditioner can be manual cleaning, and also can be cleaning by starting a self-cleaning device of the air conditioner.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
