All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a flow chart of an automatic dust removing method for an outdoor unit of an air conditioner according to an embodiment of the present invention is shown. The automatic dust removing method for the outdoor unit of the air conditioner comprises the following steps of: starting the outdoor fan to operate; detecting the accumulated running time of the outdoor fan and the state of the compressor; judging whether the accumulated running time of the outdoor fan and the state of the compressor meet the dust removal condition or not; if the requirement is met, the air conditioner outdoor unit automatically enters a dust removal mode without manual opening by a user. Wherein the dust removal conditions include: the accumulated running time meets a first preset time and the compressor is in a stop state.
Specifically, referring to fig. 2, after the outdoor fan is started to operate, detecting the accumulated operation time of the outdoor fan of the air conditioner and judging whether the accumulated operation time of the outdoor fan of the air conditioner meets a first preset time period; and if the accumulated running time of the outdoor fan of the air conditioner meets a first preset time, the outdoor unit controller sends a dust removal instruction and judges the state of the compressor, and if the compressor is in a stop state, the outdoor unit controller enters a dust removal mode. When the air conditioner is shut down or the air conditioner is shut down when reaching a preset temperature, the compressor is in a shut-down state.
And when the accumulated running time meets the first preset time and the air conditioner is in a shutdown or shutdown state, the outdoor unit of the air conditioner automatically enters a dust removal mode. If the accumulated running time meets the first preset time length but the air conditioner is not in a shutdown or shutdown state, and if the air conditioner is in the shutdown or shutdown state but the accumulated running time does not meet the first preset time length, the air conditioner outdoor unit does not enter a dust removal mode, so that the situation that the normal refrigerating and/or heating process of the air conditioner is influenced by the fact that the air conditioner outdoor unit enters the dust removal mode just after being started is avoided, and further the heat exchange efficiency of the air conditioner is improved.
Further, the automatic dust removing method for the outdoor unit of the air conditioner further comprises the following steps: adjusting an air conditioner operation mode to frost and defrost a heat exchanger of the outdoor unit; when the outdoor heat exchanger defrosts water, the outdoor fan reversely runs; and after the dust removal is finished, the compressor is recovered to a stop state. Wherein, adjusting the air conditioner operation mode to make the outdoor unit heat exchanger frost earlier and then defrost includes: starting heating operation of the air conditioner until the accumulated operation time meets a second preset time, and enabling the heat exchanger of the outdoor unit to reach a frosting state; when the temperature of the outer coil pipe reaches the preset temperature, the air conditioner switches the refrigeration mode, and the frost on the heat exchanger of the outdoor unit begins to be dissolved. And the second preset time length is greater than the first preset time length.
Specifically, after the air conditioner enters a dust removal mode, the air conditioner firstly enters a heating mode, at the moment, an indoor unit of the air conditioner releases heat to the indoor for a condenser, an outdoor unit of the air conditioner absorbs heat outdoors for an evaporator, and the temperature of the outdoor unit of the air conditioner is rapidly reduced, so that moisture in the air around the heat exchanger of the outdoor unit of the air conditioner is condensed into frost on the heat exchanger of the outdoor unit of the air conditioner; when the accumulated running time of the air conditioner meets the second preset time and the temperature of the external coil pipe meets the preset temperature, the frost on the heat exchanger of the air conditioner outdoor unit meets the preset thickness; then the air conditioner is switched to a refrigeration mode, at the moment, the air conditioner indoor unit is an evaporator, the air conditioner outdoor unit is a condenser, and the temperature of the air conditioner outdoor unit is rapidly increased, so that the frost on the heat exchanger of the air conditioner outdoor unit begins to be dissolved. And if the accumulated running time does not meet the second preset time and/or the temperature of the external coil pipe does not reach the preset temperature, the frost on the heat exchanger of the air conditioner outdoor unit does not reach the preset thickness, and the air conditioner continues to perform heating operation.
Further, when the accumulated operation time of the air conditioner external fan meets a third preset time length, all frost on the outdoor unit heat exchanger is changed into water, at the moment, the air conditioner stops refrigerating operation, and the outdoor fan reversely operates to blow air towards the outside. Through the scouring and washing action of the water formed by frost condensation and the scouring and sweeping action of the airflow formed by the reverse operation of the external fan, the blockage such as dust on the heat exchanger of the air conditioner outdoor unit is removed, and therefore the automatic dust removal effect of the air conditioner outdoor unit is achieved. And the third preset time length is greater than the second preset time length.
Further, when the accumulated operation time of the air conditioner external fan meets a fourth preset time length, the automatic dust removal mode is ended; and the compressor is recovered to a stop running state, and the accumulated running time is cleared. Specifically, when the accumulated running time meets the fourth preset time, the air conditioner recovers to a shutdown or shutdown state after the blockage such as dust on the heat exchanger of the outdoor unit of the air conditioner is removed, and the accumulated running time is cleared to zero, and the calculation of the accumulated running time of the external fan of the air conditioner is restarted. And the fourth preset time length is greater than the third preset time length.
[ second embodiment ]

In a specific embodiment, the detecting module 210, the determining module 220, and the controlling module 230 cooperate to implement the method for controlling the start of the compressor of the air conditioner according to the first embodiment. For example, after the air conditioner external fan starts to operate, the detection module 210 first detects the accumulated operation time of the external fan and the state of the compressor; then, the judging module 220 judges whether the accumulated operation time meets a first preset time and whether the compressor is in a stop operation state, if so, the control module 230 controls the air conditioner to enter a dust removal mode, and the air conditioner starts heating operation until the accumulated operation time meets a second preset time and the temperature of the external coil reaches a preset temperature; the control module 230 controls the air conditioner to switch to the cooling mode, the cooling operation is stopped when the accumulated operation time meets a third preset time length, and meanwhile the control module 230 controls an external fan of the air conditioner to reversely operate; and when the accumulated running time meets a fourth preset time, finishing the dust removal, restoring the compressor to a running stop state, resetting the accumulated running time, and recalculating the accumulated running time.
