An embodiment of the control method of the air conditioner of the present invention is proposed based on the hardware architecture of the air conditioner described above.
Referring to fig. 5, fig. 5 is a first embodiment of a control method of an air conditioner of the present invention, including the steps of:
step S10, after the air conditioner is operated, controlling the gas detection sensor to detect the preset gas in the action space of the air conditioner;
in this embodiment, the air conditioner controls the gas detection sensor to be activated after the operation. The gas sensor may be disposed at a housing of the air conditioner to detect a predetermined gas in a room, the predetermined gas being a gas having a bad smell. The gas having an offensive odor means not only a gas having an odor that can be smelled by a user but also a gas having an odor that cannot be smelled by a user, the gas having an offensive odor that can be smelled is, for example, formaldehyde gas, and the gas having an offensive odor that cannot be smelled is, for example, TVOC gas. The gas having the odor may be a gas harmful to the health of the user, and is not limited to being capable of smelling the gas having the odor.
In addition, the air conditioning device is provided with a peculiar smell removing function, and if the air conditioner enters the smell removing function, the gas detection sensor is controlled to be started to detect preset gas in the action space of the air conditioner. The working space is a space in which the air conditioner is located, and may be understood as a room.
Step S20, when it is determined that the gas detection sensor detects preset gas, closing an air outlet of the air outlet duct;
and step S30, controlling the first wind shielding structure to move so as to communicate the bypass air channel with the fresh air inlet air channel.
After the gas detection sensor detects the preset gas, the gas detection sensor sends a signal to a processor of the air conditioner, that is, the air conditioner receives the signal, so that the gas detection sensor can be determined to detect the preset gas. In contrast, the air conditioner closes the air outlet of the air outlet duct, and controls the indoor air to enter the room from the air outlet after the indoor air cannot enter the air outlet through the air return opening. The air conditioner controls the first wind shielding structure to move, so that the bypass air channel is communicated with the fresh air inlet air channel. The first wind shielding structure is controlled to move, namely the first wind shielding structure is opened, so that the bypass air channel is communicated with the fresh air inlet air channel. Because the air outlet is closed, the indoor air enters the return air duct through the return air inlet, then enters the bypass duct from the return air duct, and finally is discharged to the outside through the fresh air inlet duct and the fresh air pipeline, the indoor air is discharged to the outside through the mode, which is defined as the air exhaust mode of the air conditioner, and the trend of the indoor air in the air exhaust mode refers to fig. 6.
It should be noted that the air conditioner may set a preset threshold value of the concentration, and when the gas sensor detects the preset gas, the gas detection sensor obtains the concentration of the preset gas again. If the concentration is greater than the preset threshold value, the air conditioner starts an air exhaust mode, the air conditioner is prevented from always running the air exhaust mode when the air with slight concentration exists indoors, and therefore the condition that the fresh air mode internal circulation mode of the air conditioner cannot run normally is avoided.
The air conditioner of the embodiment starts the air exhaust mode when detecting the gas with the peculiar smell in the room, exhausts the indoor air from the room to the outside, and introduces the outdoor air through the gap of the room, thereby reducing or removing the peculiar smell in the room.
In the technical scheme that this embodiment provided, air conditioner is after the operation, and the gaseous sensor that detects of control detects the indoor gas that has the peculiar smell, if confirm that gaseous sensor that detects has the gas of peculiar smell, then control structure operation of keeping out the wind makes bypass wind channel and new trend air inlet wind channel intercommunication and close the air outlet in air-out wind channel to pass through air return wind channel, bypass wind channel and new trend air inlet wind channel with the room air and discharge into to outdoor, purify indoor peculiar smell air. Because air conditioner will have the indoor air discharge of peculiar smell through return air wind channel, bypass wind channel and new trend air inlet wind channel, and need not purify the air of peculiar smell through the HEPA net, also avoid exchanging HEPA net many times and get, saved the cost of purifying the peculiar smell.
Referring to fig. 7, fig. 7 shows a second embodiment of the control method of the air conditioner according to the present invention, which further includes, after step S30, according to the first embodiment:
step S40, acquiring the concentration of the preset gas detected by the gas detection sensor;
and step S50, controlling the indoor fan to operate according to the target rotating speed corresponding to the concentration.
In this embodiment, when the air conditioner starts the air exhaust mode to remove the indoor odor, the rotation speed of the indoor fan needs to be increased. Specifically, the gas detection sensor may detect the concentration of the preset gas. And the air conditioner stores the mapping relation between the concentration and the rotating speed of the indoor fan. And the air conditioner determines the target rotating speed according to the mapping relation and the concentration, so that the indoor fan is controlled to operate according to the target rotating speed. The higher the concentration, the higher the target rotation speed.
In addition, the air conditioner is provided with a plurality of concentration threshold values, each concentration threshold value corresponds to the rotating speed of the indoor fan, and when the concentration of the preset gas is in a certain concentration interval (the concentration interval is divided according to each concentration threshold value), the target rotating speed of the indoor fan is not lower than the rotating speed corresponding to the lower concentration threshold value of the concentration interval.
The air conditioning device may be provided with a plurality of types of gas detection sensors to detect different gases having a smell, and the different gases having a smell are correspondingly provided with a mapping relationship. For example, some odors are only irritating to the sense of smell of the user, and have little impact on the physical health of the user, so that such gases can be slowly exhausted; the other type of odor has a health influence on the user, and the odor needs to be rapidly removed, so that the rotating speed of the indoor fan corresponding to the odor with small influence on the health of the user is smaller than the rotating speed corresponding to the odor with large influence on the health of the user under the condition of the same gas concentration, namely the mapping relations corresponding to the two types of odor are different. The air conditioner determines the type of the peculiar smell gas according to the gas detection sensor for transmitting the gas concentration, extracts a corresponding mapping relation based on the type, and determines the target rotating speed of the indoor fan according to the mapping relation and the concentration.
In the technical scheme that this embodiment provided, air conditioner acquires the concentration of the gaseous concentration of predetermineeing that gas sensor detected to the control indoor fan is according to the target rotational speed operation that concentration corresponds.
Referring to fig. 8, fig. 8 shows a third embodiment of the control method of the air conditioner according to the present invention, and based on the second embodiment, the step S50 includes:
step S51, determining a concentration interval where the concentration is located;
step S52, determining the target rotating speed of the indoor fan according to the concentration interval;
and step S53, controlling the indoor fan to operate according to the target rotating speed.
In this embodiment, the air conditioner divides the concentration into a plurality of concentration sections, and each concentration section corresponds to the rotation speed or the rotation speed gear of one indoor fan. For example, the concentration is divided into three concentration ranges, namely a first range (0, C1), a second range (C1, C2) and a third range (C2, + ∞).
After the air conditioner obtains the concentration of the preset odor, the concentration interval where the concentration is located is determined, the target rotating speed of the indoor fan is determined according to the concentration interval, and then the indoor fan is controlled to operate according to the target rotating speed. For example, if the concentration is in the first interval and the odor smelled by the user is a mild odor, the indoor fan operates at the lowest rotation speed or the lowest rotation speed gear; if the concentration is in the second interval and the peculiar smell smells by the user is a moderate peculiar smell, the indoor fan operates at a higher rotating speed or a higher rotating speed gear; and if the concentration is in the third interval and the peculiar smell smells by the user is a severe peculiar smell, the indoor fan operates at the highest rotating speed or the highest rotating speed gear.
In the technical scheme provided by this embodiment, the air conditioner determines the concentration interval where the concentration is located, so as to accurately determine the target rotating speed of the indoor fan according to the concentration interval, and then control the indoor fan to operate according to the target rotating speed.
Referring to fig. 9, fig. 9 is a fourth embodiment of the control method of the air conditioner regulator according to the present invention, and based on the third embodiment, the step S52 includes:
step S521, when the concentration interval is a preset concentration interval, determining whether the indoor fan is operated;
step S522, when the indoor fan is operated, determining the rotating speed corresponding to the concentration interval as the target rotating speed of the indoor fan;
step S523, when the indoor fan is not operated, determining a preset rotation speed as a target rotation speed of the indoor fan, where a difference between the preset rotation speed and a maximum rotation speed of the indoor fan is smaller than a preset difference.
In this embodiment, the air conditioner is provided with a preset concentration interval, and the preset concentration interval refers to a concentration interval in which the medium odor gas is located. The preset gas concentration corresponding to the moderate odor is slightly higher than the lower concentration and is lower than the maximum concentration. If the odor of the moderate odor is fully dispersed in the room, the odor felt by the gas smelled by the user is weaker; if the gas with moderate odor is not fully dispersed in the room, the concentration of the gas in a certain part will be higher, and the odor sensed by the gas smelled by the user is stronger. The air is dispersed in the room, and the determination can be made by whether the indoor fan of the air conditioner is turned on. If the indoor fan is not started, the smell is not fully dispersed in the room; and if the indoor fan is started, determining that the gas is fully dispersed in the room.
In contrast, when the air conditioner determines that the concentration range is the preset concentration range, it determines whether the indoor fan is operated. If the indoor fan is operated, the gas with peculiar smell is dispersed in the room, and the rotating speed corresponding to the concentration interval is determined as the target rotating speed. If the indoor fan is not operated, the preset rotating speed is determined as the target rotating speed, the difference value between the preset rotating speed and the maximum rotating speed is smaller than the preset difference value, namely the preset rotating speed is a larger rotating speed, and therefore the air conditioner can quickly discharge peculiar smell out of a room.
In the technical scheme that this embodiment provided, air conditioner is in the concentration interval that the concentration place was confirmed for presetting the concentration interval, confirms whether indoor fan has operated to according to the result of whether indoor fan operates, the rotational speed of indoor fan of reasonable definite.
In one embodiment, when the air conditioner determines that the concentration range in which the concentration is located is the preset concentration range, the indoor fan operates at the maximum rotation speed (the preset rotation speed is a higher rotation speed), so that the concentration of the odor near the air conditioner is reduced very low, but the odor is not uniformly mixed with the air because the indoor fan is not started before, and the odor in the room is still more obvious. To this, after indoor fan operated for a period according to the target rotational speed, control air conditioner got into the new trend mode to make the gas of peculiar smell pass through outdoor air and indoor air intensive mixing, let the peculiar smell diffusion faster, the distribution is even, and after new trend mode operation for a period, at the mode of starting airing exhaust, thereby improves the effect of removing the peculiar smell. That is, since the odor is uniformly diffused, the concentration of the odor in the indoor air is stable, and the case where the concentration of the odor near the air conditioner is much lower than the concentration of the odor at other positions does not occur.
In contrast, after the air conditioner determines that the indoor fan operates at the preset rotating speed for the first preset time, the air outlet is opened firstly, and the first wind shielding structure is controlled to move so as to block the bypass air channel and the fresh air inlet air channel, so that the air conditioner enters a fresh air mode, namely, outdoor air enters the room through the fresh air inlet air channel, the return air channel and the air inlet air channel. And when the air conditioner determines that the blocking time of the bypass air channel and the fresh air inlet air channel reaches a second preset time, namely the time of the fresh air running mode reaches the second preset time, returning to the step of controlling the first wind shielding structure to move so as to communicate the bypass air channel and the fresh air inlet air channel, so that the air conditioner enters an air exhaust mode.
Referring to fig. 10, fig. 10 shows the gas flow direction of the fresh air mode of the air treatment device in this embodiment.
In this embodiment, air conditioner is in the gas concentration who confirms the peculiar smell and predetermines the concentration interval, and the indoor fan does not operate, then after the fan operates a period according to great predetermined rotational speed in the control room, gets into the new trend mode, fully diffuses the peculiar smell, reentrant air exhaust mode to improve air conditioner and get rid of the effect of peculiar smell.
In one embodiment, when the air conditioner determines that the concentration range in which the concentration is located is the preset concentration range, the indoor fan operates at the maximum rotation speed (the preset rotation speed is a higher rotation speed), so that the concentration of the odor near the air conditioner is reduced very low, but the odor is not uniformly mixed with the air because the indoor fan is not started before, and the odor in the room is still more obvious. To this, after indoor fan operated for a period according to the target rotational speed, control air conditioner got into the inner loop mode to make the gas and the indoor air intensive mixing of peculiar smell, let the peculiar smell diffusion faster, it is even to distribute, and after inner loop mode operation for a period, at the mode of starting airing exhaust, thereby improve the effect of removing the peculiar smell. That is, since the odor is uniformly diffused, the concentration of the odor in the indoor air is stable, and the case where the concentration of the odor near the air conditioner is much lower than the concentration of the odor at other positions does not occur.
In contrast, after the air conditioner determines that the indoor fan operates at the preset rotating speed for the first preset time, the air outlet is opened firstly, the first wind shielding structure is controlled to move so as to block the bypass air channel and the fresh air inlet air channel, and the second wind shielding structure is controlled to move so as to block the return air channel and the fresh air inlet air channel, so that the air conditioner enters an internal circulation mode, namely, indoor air enters the room through the return air channel, the bypass air channel and the outlet air channel. And when the air conditioner determines that the blocking time of the bypass air channel and the fresh air inlet air channel reaches a second preset time, namely the time of the operation of the internal circulation mode reaches a third preset time, returning to execute the step of controlling the first wind shielding structure to move so as to communicate the bypass air channel and the fresh air inlet air channel, so that the air conditioner enters an air exhaust mode.
Referring to fig. 11, fig. 11 shows the gas flow direction of the internal circulation mode of the air treatment device in this embodiment.
In this embodiment, the air conditioner is in presetting the concentration interval at the gas concentration of confirming the peculiar smell, and the indoor fan does not operate, then after controlling indoor fan and operating for a period of time according to great predetermined rotational speed, gets into the inner loop mode, fully diffuses the peculiar smell, gets into the mode of airing exhaust again to improve the effect that air conditioner got rid of the peculiar smell.
In an embodiment, the air conditioner is further provided with a second wind blocking structure, and the second wind blocking structure is movably connected to a joint of the fresh air inlet duct and the return air duct so as to selectively communicate or block the bypass duct from communicating with the fresh air inlet duct or block the fresh air inlet duct from communicating with the return air duct. Therefore, when the air conditioner enters an air exhaust mode, the first air blocking structure is controlled to move to communicate the bypass air channel and the fresh air inlet air channel, the second air blocking structure is controlled to move to block the fresh air inlet air channel and the return air channel, indoor air is prevented from flowing back to the indoor space through the fresh air inlet air channel, the return air channel and the air outlet channel, and the effect of the air conditioner for treating peculiar smell is improved.
