The following describes a control method and system of an air conditioner and the air conditioner according to an embodiment of the application with reference to the accompanying drawings.
Before describing a control method and system of an air conditioner and the air conditioner according to an embodiment of the present application, the air conditioner will be first explained.

Specifically, as shown in fig. 7, the air guide mechanism J of the air conditioning indoor unit 1000 further includes: and an air outlet frame F. The air outlet frame F comprises a rear plate F1, and a ventilation hole F4 is formed in the rear plate F1. The guide ring G is arranged in the air outlet frame F, the axis of the guide ring G is perpendicular to the ventilation hole F4, a first air duct A4 penetrating through the length direction of the guide ring G along the axial direction of the guide ring G is limited in the guide ring G, the first air duct A4 is communicated with the air inlet A1 and the first air outlet A21, and the second air outlet A22 is limited between the air outlet frame F and the guide ring G. It can be understood that a part of the air from the air inlet a1 can flow forward through the ventilation hole F4, and then flow through the first air duct a4 and enter the room from the first air outlet a 21. Another part of the air sent by the air inlet a1 can be guided through the position between the air outlet frame F and the air guide ring G and enter the room from the second air outlet a 22. Therefore, air in the air inlet A1 can be guided in multiple modes, the air flowing range is enlarged, and the air supply effect of the air guide mechanism J is improved.
In some embodiments, as shown in fig. 7, the wind guide blade 100 includes: a plurality of transverse vanes 110. The plurality of horizontal guide vanes 110 are respectively rotatably arranged in the air outlet frame F and positioned on the front side of the flow guide ring G, the plurality of horizontal guide vanes 110 are arranged at intervals in the vertical direction, at least one part of the plurality of horizontal guide vanes 110 is provided with a groove 1101 for accommodating the flow guide ring G, and the parts of the horizontal guide vanes 110 positioned on the two sides of the groove 1101 extend backwards to the rear side of the front end of the flow guide ring G. It will be appreciated that the grooves 1101 may be arranged such that the portions of the transverse vanes 110 on either side of the grooves 1101 extend rearwardly to the rear of the forward end of the flow guiding ring G. Thus, the distance between the transverse guide vane 110 and the first fan D (i.e. the axial flow fan) is shortened, the air volume for air supply is increased, and the air supply range of the transverse guide vane 110 can be expanded, thereby improving the air supply effect of the transverse guide vane 110.
In some embodiments, as shown in fig. 8, a vane N1 is movably disposed on the wind scooper N between a first position at which the vane N1 opens the first outlet opening a21 and a second position at which the vane N1 closes the first outlet opening a 21. Thus, when the stationary blade N1 opens the first outlet a21, the air in the first inlet a1 can flow through the wind scooper N and flow out of the first outlet a21, and the wind scooper N can guide the flow of the air, thereby expanding the air outlet range. When the stationary blade N1 closes the first outlet a21, the stationary blade N1 may also block particles such as dust in the outside air, thereby improving the cleanliness of the inside of the indoor unit 1000 of the air conditioner.
Specifically, as shown in fig. 9, the wind scooper N includes: a swirl mount N2 and a blade drive plate N3. The cyclone mounting frame N2 is fixed at the first air outlet A21, and the cyclone mounting frame N2 comprises an outer ring N21 and a fixing ring N22 positioned in the middle of the outer ring N21. A blade driving plate N3 is provided on the cyclone mounting frame N2 and rotatable around an outer ring N21, one end of a stationary blade N1 is connected to a stationary ring N22 and rotatable in a radial direction with respect to a stationary ring N22, and the other end of a stationary blade N1 is connected to the blade driving plate N3 to drive the stationary blade N1 to move between a first position and a second position. That is, one end of the stationary blade N1 is connected to the stationary ring N22 so that the swirl mounting frame N2 can serve as a stopper for the stationary blade N1, while one end of the stationary blade N1 is rotatable in the radial direction with respect to the stationary ring N22, so that when the blade driving plate N3 drives the other end of the stationary blade N1 to rotate, the one end of the stationary blade N1 can radially follow the other end of the stationary blade N1 with respect to the outer ring N21 of the swirl mounting frame N2.
Further, as shown in fig. 9, a mounting hole N221 is provided in the peripheral wall of the fixed ring N22, and one end of the stationary blade N1 passes through the mounting hole N221 and is rotatable in the mounting hole N221. That is, the installation hole N221 is provided to rotatably connect one end of the stationary vane N1 with the stationary ring N22, so that one end of the stationary vane N1 can be relatively rotated in the installation hole N221.
In some alternative embodiments, as shown in fig. 9, the blade driving plate N3 is sleeved outside the outer ring N21, wherein the outer ring N21 is provided with a mounting groove N212, and the stator blade N1 is supported in the mounting groove N212. It can be understood that the blade driving plate N3 is sleeved outside the outer ring N21, so that the outer ring N21 can limit the position of the blade driving plate N3.

One end of the blade N10 is connected with the fixed ring N22, and the other end of the blade N10 is provided with a sleeve N101. A first end of the piston shaft N12 is connected to the vane drive plate N3 and a second end of the piston shaft N12 is telescoped within the sleeve N101 to move the vane N10 between the first and second positions. That is, the first end of the piston shaft N12 is driven by the vane driving plate N3 to rotate relatively, so that the second end of the piston shaft N12 can telescope to drive the other end of the vane N10 to rotate, one end of the vane N10 rotates along with the other end of the vane N10 relative to the fixing ring N22, and the whole vane N10 can move between the first position and the second position.
Specifically, as shown in fig. 10, the first end of the piston shaft N12 is connected to the blade driving plate N3 by a ball joint. It can be understood that the arrangement of the spherical hinge enables the rotation between the first end of the piston shaft N12 and the blade driving plate N3 to be more flexible, and the air guide range of the blade N10 can be expanded.

Namely: if the air supply distance is larger than the preset distance, the user is far away from the air conditioner, at the moment, the air supply distance can be effectively increased in a mode of starting the centrifugal fan, and therefore the temperature in the far distance is rapidly reduced to meet the user requirements. And only the centrifugal fan is started, so that the energy consumption of the air conditioner can be effectively reduced while the user requirements are met compared with the condition that the axial fan and the centrifugal fan operate simultaneously in the operation process of the central air conditioner in the related art.
S103: if the distance is smaller than or equal to the preset distance, the axial flow fan is independently started, and the air guide mechanism is controlled to be opened to the maximum air guide angle.
Namely: if the distance is smaller than or equal to the preset distance, the user is considered to be a relatively strong distance away from the air conditioner, at the moment, the axial flow fan is started, the air conditioner has the advantage of high operation efficiency, and only the axial flow fan is started, so that the axial flow fan and the centrifugal fan operate simultaneously in the operation process of the air conditioner in the center of the related art, the energy consumption of the air conditioner can be effectively reduced, and the operation efficiency of the air conditioner is improved.
As shown in fig. 4 to 10, the controlling the air guiding mechanism to open to the maximum air guiding angle includes: controlling the lateral guide vanes 110 to swing to a parallel position, i.e.: the maximum air outlet position of 90 degrees, and at the same time, the rotational flow air guide strip (the static blade) is controlled to rotate to the maximum air outlet position of 90 degrees (namely, the plane where the static blade is vertical to the air outlet).
In the above description, the distance between the user and the air conditioner indoor unit may be detected by a preset distance sensor. In a specific example, the predetermined distance is, but is not limited to, 5 meters.
According to the control method of the air conditioner, the user requirements can be met, meanwhile, the operation efficiency of the air conditioner is improved, the energy consumption of the air conditioner is reduced, and further the use experience of the air conditioner is improved.

Further, after increasing the rotational speed of the centrifugal fan to the maximum rotational speed, the method further includes: and if the indoor temperature does not reach the target temperature, further starting the axial flow fan. Therefore, the indoor temperature can meet the requirements of users, and the comfort of the users is improved.
In a specific example, if the indoor temperature is greater than the target temperature, when the distance is less than or equal to the predetermined distance, the method further includes: and increasing the rotating speed of the axial flow fan, otherwise, maintaining the rotating speed of the axial flow fan unchanged.
Specifically, first, the distance L1 between the user and the housing is detected, and the magnitude of the detection value L1 and the set value L2 is determined; a distance sensor is arranged on the shell;
if L1 (the distance between the user and the air conditioner indoor unit) is less than or equal to L2 (preset distance), the near wind mode is automatically started: the method comprises the steps of opening an axial flow motor singly, returning a horizontal air guide strip to a horizontal air outlet position, returning a rotational flow air guide strip to a 90-degree air outlet position, then obtaining an indoor temperature T1, comparing the indoor temperature T1 with a target temperature T2, and increasing the rotating speed of an axial flow fan if T1 is greater than T2, wherein the increased rotating speed is the maximum value of a set rotating speed interval, otherwise, maintaining the rotating speed of the axial flow fan unchanged.
If L1> L2, then the mid-far wind mode is automatically turned on: the centrifugal motor is singly started, meanwhile, the horizontal air guide strips return to the horizontal air outlet position, the rotational flow air guide strips return to the 90-degree air outlet position, the indoor temperature T1 and the target temperature T2 are compared, if T1 is greater than T2, the rotating speed of the centrifugal fan is increased, and the increased rotating speed is the maximum value of the set rotating speed interval; otherwise, maintaining the centrifugal rotating speed unchanged;
during the period of starting the middle and far wind mode, the indoor temperature T1 is periodically acquired, the indoor temperature T1 is compared with the target temperature T2, and if L1 is still larger than L2, the far wind mode is automatically started: restore axial fan and centrifugal fan rotational speed to corresponding rated revolution, return horizontal wind guide strip to horizontal air-out position simultaneously, whirl wind guide strip returns to 90 degrees air-out positions, promptly: meanwhile, the indoor temperature can reach the expectation of the user as much as possible by starting the air conditioner, and further, the user requirements are met quickly.

Specifically, the air duct comprises a first air duct 1 and a second air duct 2 system, the first air duct 1 is an axial flow air duct, the second air duct 2 is a centrifugal air duct, and the first air duct 1 is positioned vertically above the second air duct 2; the evaporator is positioned right behind the air duct system, is of a sectional or integral design and comprises a first evaporator 3 and a second evaporator 4, the first evaporator is positioned vertically above the second evaporator 4, wherein the first evaporator 3 occupies 1/3 of the total evaporator area, and the second evaporator 4 occupies 2/3 of the total evaporator area; the first evaporator 3 is positioned right in front of the first air duct 1, and the second evaporator 4 is positioned right in front of the second air duct 2; the air outlet is arranged right ahead of the first air duct 1. The inlet of the first evaporator is provided with a first electronic expansion valve, and the inlet of the second evaporator is provided with a second electronic expansion valve. The first evaporator is for example a parallel flow evaporator and the second evaporator is for example a fin evaporator.
When the distance is greater than the predetermined distance, the method further comprises the following steps: independently starting the second throttling device; when the distance is less than or equal to the preset distance, the method further comprises the following steps: the first throttle device is turned on alone. Thereby, the system energy consumption can be further reduced.
Specifically, when the near air mode is started, the axial flow fan is started, and when the first electronic expansion valve is closed, the refrigerant only flows through the second evaporator, but not through the first evaporator, so that the refrigerant flow is reduced, and the power is reduced; similarly, the system power can be greatly reduced when the far wind is opened, and the purpose of energy conservation is achieved.
According to the control method of the air conditioner, the axial flow fan and the centrifugal fan can be selectively started according to the air supply distance required by a user, the rotating speed of the fan is flexibly adjusted according to the difference value between the indoor temperature and the target temperature, the requirement of the air supply distance is met, the requirement of the environment comfortable temperature is met, and meanwhile the energy consumption of the air conditioner is effectively reduced.
