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.
It should be noted that the terms "first", "second" and "third" in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The problem that the existing air conditioner cannot judge the time for starting the self-cleaning mode is pointed out based on the background technology. The invention provides a self-cleaning control method for an air conditioner and the air conditioner, aiming at enabling the air conditioner to automatically judge whether to execute a self-cleaning mode.
Specifically, the air conditioner of the present invention includes an indoor unit, a compressor, and an outdoor unit, and as shown in fig. 1, the self-cleaning control method of the present invention includes: when the air conditioner operates, acquiring the temperature of a coil pipe of an indoor unit; and judging whether to execute a self-cleaning mode or not according to the temperature of the coil pipe of the indoor unit. The coil temperature of the indoor unit can be acquired through the coil temperature sensor of the indoor unit. In addition, the self-cleaning of the air conditioner is mainly carried out on an indoor unit and an outdoor unit of the air conditioner.
Preferably, as shown in fig. 2, the step of determining whether to execute the self-cleaning mode according to the coil temperature of the indoor unit includes: judging whether the coil temperature of the indoor unit is greater than a first standard temperature value or not; if the coil temperature of the indoor unit is greater than the first standard temperature value, at least one of the exhaust temperature of the compressor and the coil temperature of the outdoor unit is further acquired; judging whether to execute a self-cleaning mode according to at least one of the exhaust temperature of the compressor and the coil temperature of the outdoor unit; if the coil temperature of the indoor unit is not greater than the first standard temperature value, the self-cleaning mode is not executed. It should be noted that, in the technical description of the present invention, "the self-cleaning mode is not performed" may be understood as not immediately performing the self-cleaning mode, i.e., performing the self-cleaning mode with a delay. The exhaust temperature of the compressor can be obtained through the exhaust temperature sensor, and the coil temperature of the outdoor unit can be obtained through the outdoor unit coil temperature sensor. The preferred embodiments of the present invention are illustrated in detail below by three examples.
Example one
As shown in fig. 2, the step of determining whether to perform the self-cleaning mode according to at least one of a discharge temperature of the compressor and a coil temperature of the outdoor unit includes: executing a self-cleaning mode if the discharge temperature of the compressor is greater than a second standard temperature value; if the exhaust temperature of the compressor is not greater than the second standard temperature value, further judging whether the temperature of the coil pipe of the outdoor unit is greater than a third standard temperature value; if the temperature of the coil pipe of the outdoor unit is larger than the third standard temperature value, executing a self-cleaning mode; if the coil temperature of the outdoor unit is not greater than the third standard temperature value, the self-cleaning mode is not performed. That is, on the premise that the coil temperature of the indoor unit is greater than the first standard temperature value, the air conditioner firstly judges whether the exhaust temperature of the compressor is greater than a second standard value (i.e. judges whether the exhaust temperature of the compressor is too high), if the exhaust temperature of the compressor is too high, the self-cleaning mode is immediately executed without judging whether the coil temperature of the outdoor unit is greater than a third standard temperature value; if the discharge temperature of the compressor is not high, whether the temperature of the coil of the outdoor unit is larger than a third standard temperature value or not is continuously judged (namely whether the temperature of the coil of the outdoor unit is too high or not is judged), if the temperature of the coil of the outdoor unit is too high, the self-cleaning mode is immediately executed, and if the temperature of the coil of the outdoor unit is not high, the self-cleaning mode is not executed.
Example two
As another modification of the first embodiment, the step of determining whether to perform the self-cleaning mode according to at least one of a discharge temperature of the compressor and a coil temperature of the outdoor unit includes: if the temperature of the coil pipe of the outdoor unit is larger than the third standard temperature value, executing a self-cleaning mode; if the temperature of the coil pipe of the outdoor unit is not greater than the third standard temperature value, further judging whether the exhaust temperature of the compressor is greater than the second standard temperature value; executing a self-cleaning mode if the discharge temperature of the compressor is greater than a second standard temperature value; the self-cleaning mode is not performed if the discharge temperature of the compressor is not greater than the second standard temperature value. The difference between this embodiment and the first embodiment is: in the first embodiment, when the temperature of the coil pipe of the indoor unit is too high, it is determined whether the temperature of the exhaust gas of the compressor is too high first, and then it is determined whether the temperature of the coil pipe of the outdoor unit is too high. The control logic of this embodiment is similar to that of the first embodiment, and therefore, the description thereof is not repeated herein.
EXAMPLE III
As another modification of the first and second embodiments, the step of determining whether to perform the self-cleaning mode according to at least one of a discharge temperature of the compressor and a coil temperature of the outdoor unit includes: judging whether the exhaust temperature of the compressor is greater than a second standard temperature value or whether the coil temperature of the outdoor unit is greater than a third standard temperature value; if the discharge temperature of the compressor is greater than the second standard temperature value and/or the coil temperature of the outdoor unit is greater than the third standard temperature value, executing a self-cleaning mode; if the discharge temperature of the compressor is not greater than the second standard temperature value and the coil temperature of the outdoor unit is not greater than the third standard temperature value, the self-cleaning mode is not performed. The present embodiment is different from the first and second embodiments in that: in this embodiment, when the temperature of the coil of the indoor unit is too high, it is determined whether the temperature of the discharge air of the compressor is too high or whether the temperature of the coil of the outdoor unit is too high.
In summary, on the premise that the coil temperature of the indoor unit is greater than the first standard temperature value, the air conditioner immediately executes the self-cleaning mode as long as at least one of the discharge temperature of the compressor is greater than the second standard temperature value and the coil temperature of the outdoor unit is greater than the third standard temperature value is satisfied, regardless of whether the discharge temperature of the compressor is determined first and then the coil temperature of the outdoor unit is determined, or the coil temperature of the outdoor unit is determined first and then the discharge temperature of the compressor is determined, and then the discharge temperature of the compressor and the coil temperature of the outdoor unit are determined at the same time.
In an embodiment of the present invention, the first standard temperature value may be measured before the air conditioner is shipped, that is, the air conditioner is in a completely clean state, and may be measured by dividing the outdoor operating condition into several regions according to temperature, for example, below 25 ℃, 25 to 30 ℃, 30 to 35 ℃, 35 to 40 ℃ and above 40 ℃. In practical application, the frequency of the compressor, the air speed of the indoor unit and the air speed of the outdoor unit can be fixed, the temperature is set to be 25 ℃, the air conditioner is enabled to operate, and the temperature range value of the inner coil pipe is read when the indoor temperature is close to 25 ℃ (namely the deviation is +/-1 ℃) and the operation time is more than 20min, so that the standard temperature value under the standard working condition is obtained. Likewise, the temperature range values of 25 to 30 ℃, 30 to 35 ℃, 35 to 40 ℃ and over 40 ℃ under several standard conditions can be read in the same manner. By the mode, the standard temperature value under each working condition can be obtained, and the standard temperature values under each working condition can be written into the computer board and/or the background data, so that the air conditioner can be conveniently compared with the standard temperature values when the air conditioner runs after leaving a factory. Similarly, the second standard temperature value of the discharge temperature of the compressor and the third standard temperature value of the coil temperature of the outdoor unit under each working condition can be obtained by adopting the testing method.
In addition, the first standard temperature value, the second standard temperature value and the third standard temperature value may be determined through the above experimental method, and may also be obtained through experience of a person skilled in the art, and the person skilled in the art may flexibly obtain the first standard temperature value, the second standard temperature value and the third standard temperature value in various ways in practical applications, as long as the demarcation point determined by the first standard temperature value can determine whether the coil temperature of the indoor unit is too high, the demarcation point determined by the second standard temperature value can determine whether the exhaust temperature of the compressor is too high, and the demarcation point determined by the third standard temperature value can determine whether the coil temperature of the outdoor unit is too high.
Preferably, the step of determining whether to execute the self-cleaning mode according to the coil temperature of the indoor unit further includes: and if the execution times of the step of judging whether the temperature of the coil pipe of the indoor unit is greater than the first standard temperature value reach the preset times, immediately executing the self-cleaning mode. The preset times can be set by a person skilled in the art through an experimental manner, or can be set through an empirical manner, as long as the air conditioner can execute the self-cleaning mode through the demarcation point determined by the preset times. For example, the preset number of times may be 5, that is, when the number of times of performing the step of determining whether the coil temperature of the indoor unit is greater than the first standard temperature value reaches 5 times, the air conditioner immediately and automatically performs the self-cleaning mode.
Preferably, the self-cleaning control method of the present invention further comprises: if the operation time of the air conditioner reaches a preset time, the self-cleaning mode is immediately performed. The skilled person can set the preset time through an experimental manner, or can set the preset time through an empirical manner, as long as the air conditioner can execute the self-cleaning mode through the demarcation point determined by the preset time. For example, the preset time may be 10h (hours), that is, when the operation time of the air conditioner reaches 10h, the air conditioner automatically performs the self-cleaning mode immediately.
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.
