Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
As shown in fig. 1, fig. 1 shows an air supply device, which may be a fresh air blower, an air conditioner with a fresh air function, an air purifier, or a ventilation fan. The air supply device comprises: the air conditioner comprises a case 1, a fan 10, an air inlet interface 11 and a controller 13.
The fan 10 is disposed in the cabinet 1. The air inlet interface 11 extends out of the case 1. The fan 10 is connected with the air inlet interface 11 through a pipeline. The fan 10 includes a motor and an impeller. The impeller is sleeved on a main shaft of the motor. The motor can drive the impeller to rotate, and negative pressure is formed at the air outlet port 11 when the impeller rotates. The controller 13 is electrically connected to the motor of the blower 10. The controller 13 can control the start and stop of the motor and the rotation speed of the motor. Thus, the controller 13 can drive the fan 10 to supply air to the air inlet 11, and can control the rotation speed of the fan 10.
The air inlet interface 11 can be externally connected with an air inlet pipe 2 with various pipe diameters, and the air supply device sucks outdoor air through the air inlet pipe 2. The air inlet interface 11 is externally connected with the air inlet pipe 2 with different pipe diameters by adopting the following mode:
the air inlet interface 11 can be connected with the air inlet pipes 2 with different pipe diameters through different adapters; the air inlet pipe 3 can be a hose, and one end of the air inlet pipe 3 with different pipe diameters can be tied on the air inlet connector 11.
As shown in fig. 2, the present embodiment also proposes a control method of an air supply device, the control method being implemented based on the air supply device, the control method including the steps of:
s1: the controller 13 receives the start air supply instruction, and acquires the current pipe diameter of the air inlet pipe 2 connected with the air inlet interface 11.
The start air supply command is used for instructing the controller 13 to drive the fan 10 to supply air. The air supply starting instruction may be sent to the controller 13 by a user through a control panel of the air supply device or a remote controller, or the air supply starting instruction may be sent through a mobile terminal, and the mobile terminal and the controller 13 may be connected through a local area network or the internet. The mobile terminal can be a mobile phone or a tablet computer.
The current air inlet pipe 2 is the air inlet pipe 2 which is communicated with an air inlet interface 11 of an air supply device.
The current pipe diameter information of the air inlet pipe 2 can be stored in the controller 13 in advance through a manual setting mode. For example, when the air supply device is used for parameter configuration for the first time, the current pipe diameter information of the air inlet pipe 2 is input into the controller 13 through a control panel, a remote controller or a mobile terminal.
After the controller 13 receives the start air supply instruction, the current pipe diameter information of the air inlet pipe 2 is called.
S2: the controller 13 obtains a preset rotating speed corresponding to the current pipe diameter of the air inlet pipe 2, and the preset rotating speed has a trend of decreasing along with the increase of the pipe diameter at the same wind speed gear.
The controller 13 is pre-stored with the corresponding relationship between the various pipe diameters of the air inlet pipe 2 and the preset rotating speeds of the fan 10, and the corresponding relationship between the pipe diameters of the air inlet pipe 2 and the preset rotating speeds of the fan 10 can be stored in a form of a table. The preset rotating speed has a tendency of decreasing with the increase of the pipe diameter. The controller 13 can inquire the preset rotating speed corresponding to the pipe diameter according to the pipe diameter.
For example, the pipe diameters of the air inlet pipe 2, to which the air inlet port 11 can be externally connected, are d1, d2, and d3, respectively, where d1< d2< d3. The preset rotating speeds are respectively N1, N2 and N3, the pipe diameter d1 corresponds to the preset rotating speed N1, the pipe diameter d2 corresponds to the preset rotating speed N2, and the pipe diameter d3 corresponds to the preset rotating speed N3. The relation of N1, N2, N3 may be N1= N2> N3, or N1> N2= N3. When the diameter of the current air inlet pipe 2 is d1, the preset rotating speed is N1.
It should be noted that the pipe diameters d1, d2, and d3 of the air inlet pipe 2 may be a specific numerical value respectively, or may be a range of values respectively.
S3: the controller 13 drives the fan 10 to supply air to the air inlet port 11 at a preset rotating speed corresponding to the current pipe diameter of the air inlet pipe 2.
After acquiring the preset rotating speed corresponding to the current pipe diameter of the air inlet pipe 2, the controller 13 drives the fan 10 to rotate according to the preset rotating speed, and the fan 10 supplies air to the air inlet pipe 2 through the air inlet interface 11. The preset rotating speed has a tendency of decreasing along with the increase of the pipe diameter, if the pipe diameter of the current air inlet pipe 2 is larger, the fan 10 runs at a lower rotating speed, the air outlet volume is not too high, and thus, the generation of too large noise can be avoided; if the diameter of the current air inlet pipe 2 is smaller, the fan 10 runs at a higher rotating speed, and the air outlet quantity cannot be too small, so that the problem of too small air outlet speed can be avoided.
In an exemplary embodiment, a plurality of wind speed gears may be configured in the controller 13. The plurality of wind speed gears may be, for example, "strong gear", "high gear", "medium gear", and "low gear", respectively. The preset rotating speeds corresponding to the pipe diameters of the same air inlet pipe 2 under different wind speed gears are different. For example, when the pipe diameter of the air inlet pipe 2 is minimum, the preset rotation speeds corresponding to "strong gear", "high gear", "middle gear" and "low gear" are sequentially increased.
Under same wind speed gear, for example, under any one wind speed gear in "powerful grade", "high grade", "middle grade" and "low grade", the lower preset rotational speed is the pipe diameter that corresponds air-supply line 2 is big more. For example, the pipe diameters of the air inlet pipe 2, to which the air inlet port 11 can be externally connected, are d1, d2, and d3, respectively, where d1< d2< d3. Under "powerful shelves", a plurality of rotational speeds of predetermineeing are N1, N2, N3 respectively, and pipe diameter d1 is corresponding to predetermineeing rotational speed N1, and pipe diameter d2 is corresponding to predetermineeing rotational speed N2, and pipe diameter d3 is corresponding to predetermineeing rotational speed N3. The relation of N1, N2 and N3 is N1> N2> N3.
In step S2, obtain the corresponding predetermined rotational speed of the pipe diameter with current air-supply line, include: and acquiring a preset rotating speed corresponding to the pipe diameter of the current air inlet pipe under a set wind speed gear.
In step S1, the start air blowing command includes information of a set wind speed gear. For example, when the user sends an air blow start command to the controller 13 via a remote controller or a mobile terminal, the remote controller selects one wind speed stage as a set wind speed stage to be added to the air blow start command.
Set up a plurality of wind speed gears and can let the user independently set for air supply device's air supply wind speed, simultaneously, under same wind speed gear, the rotational speed of predetermineeing that lower is the bigger corresponding air-supply line 2's pipe diameter, then can avoid the great too big problem of noise of messenger of current air-supply line 2's pipe diameter and the problem of current air-supply line 2's pipe diameter undersize and air-out wind speed undersize under this wind speed gear.
In an exemplary embodiment, the air-moving device further includes a detection assembly 12. The detection component 12 is used for detecting the current pipe diameter of the air inlet pipe 2. The detection assembly 12 is electrically connected to the controller 13. The detection component 12 is used for detecting the current pipe diameter of the air inlet pipe 2 and sending the detection result to the controller 13.
The detection assembly 12 includes a plurality of position switches 121. The plurality of position switches 121 are electrically connected to the controller 13. A plurality of position switches 121 are all disposed on the air intake interface 11. The air inlet connection 11 is designed as a tubular structure. The air inlet port 11 may be configured as a straight pipe with a pipe diameter varying along the extending direction thereof. In the direction away from the box 1, the pipe diameter of the air inlet port 11 has a tendency to decrease. As shown in fig. 3 to 6, the position switches 121 are disposed on the outer peripheral wall of the air inlet port 11 and are sequentially arranged along the axial direction of the air inlet port 11.
The air inlet pipe 2 is sleeved on the air inlet interface 11 and can be abutted against a position switch 121 to trigger the position switch 121. The air inlet pipes 2 with different pipe diameters trigger the position switches 121 at different positions. The larger the diameter of the air inlet pipe 2 is, the closer the air inlet pipe 2 is to the box body 1 when the air inlet pipe 2 is sleeved on the air inlet port 11, and the closer the position switch 121 triggered by the air inlet pipe 2 is to the box body 1. The position switches 121 are corresponding to the air inlet pipes 2 with various pipe diameters one by one, the pipe diameter of the air inlet pipe 2 corresponding to the position switch 121 closer to the box body 1 is larger, and the air inlet pipe 2 with larger pipe diameter can be detected by the position switch 121 closer to the box body 1. When a position switch 121 is triggered, the position switch 121 sends a trigger signal to the controller 13.
The control method also comprises the following steps before the pipe diameter of the current air inlet pipe connected with the air inlet interface is obtained:
after any position switch 121 is triggered, the pipe diameter of the air inlet pipe corresponding to the triggered position switch 121 is stored as the current pipe diameter of the air inlet pipe.
From this, the pipe diameter of current air-supply line can come out through detecting element automated inspection, need not artificial pipe diameter to current air-supply line and carries out parameter configuration, reduces artificial operation, promotes user experience.
In an exemplary embodiment, as shown in fig. 3 and 4, the air inlet interface 11 of the air supply device 1 is provided as a cone-shaped cylinder. The bigger one end of air inlet interface 11 diameter is towards box 1, and the less one end of air inlet interface 11 diameter deviates from box 1. A plurality of position switches 121 are sequentially arranged along the extending direction of the air inlet port 11. The pipe diameters of the air inlet interfaces 11 where the position switches 121 are located are different. The larger the diameter of the air inlet pipe 2 is, the closer the air inlet pipe 2 is to the box body 1 when the air inlet pipe 2 is sleeved on the air inlet port 11, and the closer the position switch 121 triggered by the air inlet pipe 2 is to the box body 1. The position switches 121 are corresponding to the air inlet pipes 2 with various pipe diameters one by one, the pipe diameter of the air inlet pipe 2 corresponding to the position switch 121 closer to the box body 1 is larger, and the air inlet pipe 2 with larger pipe diameter can be detected by the position switch 121 closer to the box body 1.
In another embodiment, as shown in fig. 5 and 6, the outer peripheral surface of the air inlet port 11 is stepped, and the outer peripheral surface includes a plurality of cylindrical surfaces 111. The cylindrical surface 111 may be a cylindrical surface. The diameters of the plurality of cylindrical surfaces 111 sequentially vary from large to small. The diameter of the cylindrical surface 111 increases closer to the casing 1. A position switch 121 is provided on each cylindrical surface 111. The air inlet pipes 2 with various pipe diameters correspond to the cylindrical surfaces 111 one by one, and the air inlet pipe 2 with each pipe diameter can be sleeved on the corresponding cylindrical surface 111. When the air inlet pipe 2 is sleeved on the corresponding cylindrical surface 111, the position switch 121 on the cylindrical surface 111 is triggered.
In an exemplary embodiment, a plurality of wind speed steps may be configured in the controller 13. The plurality of wind speed gears may be, for example, "strong gear", "high gear", "medium gear", and "low gear", respectively.
A plurality of rotational speed groups are also arranged in the controller 13. The number of the rotating speed groups is the same as the number of the air inlet pipes 2 with different pipe diameters, which can be connected with the air inlet interfaces 11, and the rotating speed groups correspond to the pipe diameters of the air inlet pipes 2 one by one. A plurality of preset rotating speeds are arranged in each rotating speed group, and the number of the preset rotating speeds in each rotating speed group is the same as that of the wind speed gears. A plurality of preset wind speeds in each group of wind speeds correspond to wind speed gears one by one. In each group of wind speeds, as the wind speed gear rises, the numerical value of the preset wind speed corresponding to the wind speed gear also rises.
All the preset rotating speeds corresponding to at least one wind speed gear have a trend of decreasing along with the increase of the pipe diameter corresponding to the rotating speed group in which the rotating speed gear is positioned.
For example, the pipe diameters of the air inlet pipe 2, to which the air inlet port 11 can be mounted, are d1, d2, d3, respectively, d1< d2< d3. The plurality of rotation speed groups are respectively a rotation speed group A, a rotation speed group B and a rotation speed group C. The pipe diameter d1 of the air inlet pipe 2 corresponds to the rotating speed group A; the pipe diameter d2 of the air inlet pipe 2 corresponds to the rotating speed group B; the pipe diameter d3 of the air inlet pipe 2 corresponds to the rotating speed group C.
The rotation speed group a comprises preset rotation speeds a1, a2, a3 and a4, wherein a1> a2> a3> a4. The corresponding relation between the wind speed gear and the various preset rotating speeds contained in the rotating speed group A is as follows: the strong gear corresponds to a preset rotating speed a1 in the rotating speed group A, the high gear corresponds to a preset rotating speed a2 in the rotating speed group A, the middle gear corresponds to a preset rotating speed a3 in the rotating speed group A, and the low gear corresponds to a preset rotating speed a4 in the preset rotating speed group A.
The rotation speed group B includes preset rotation speeds B1, B2, B3, B4, B1> B2> B3> B4. The corresponding relationship between the wind speed gear and the multiple preset rotating speeds contained in the rotating speed group B is as follows: the "strong gear" corresponds to a preset rotation speed B1 in the rotation speed group B, the "high gear" corresponds to a preset rotation speed B2 in the rotation speed group B, the "medium gear" corresponds to a preset rotation speed B3 in the rotation speed group B, and the "low gear" corresponds to a preset rotation speed B4 in the rotation speed group B.
The rotation speed group C includes preset rotation speeds C1, C2, C3, C4, C1> C2> C3> C4. The corresponding relation between the wind speed gear and the various preset rotating speeds contained in the rotating speed group C is as follows: the "strong gear" corresponds to a preset rotation speed C1 in the rotation speed group C, the "high gear" corresponds to a preset rotation speed C2 in the rotation speed group C, the "medium gear" corresponds to a preset rotation speed C3 in the rotation speed group C, and the "low gear" corresponds to a preset rotation speed C4 in the rotation speed group C.
Wherein at least one of the following configurations exists in the controller 13: the preset rotation speeds a1, b1, c1 have a decreasing trend, such as a1> b1> c1, or a1> b1= c1, or a1= b1> c1; the preset rotation speeds a2, b2, c2 have a decreasing tendency, for example a2> b2> c2, or a2> b2= c2, or a2= b2> c2; the preset rotation speeds a3, b3, c3 have a decreasing trend, such as a3> b3> c3, or a3> b3= c3, or a3= b3> c3; the preset rotation speeds a4, b4, c4 have a tendency to decrease, for example a4> b4> c4, or a4> b4= c4, or a4= b4> c4.
In step S1, the start air blowing command includes information of a set wind speed gear. For example, when the user sends an air supply start instruction to the controller 13 via a remote controller or a mobile terminal, the remote controller selects a wind speed range as a set wind speed range to be added to the air supply start instruction, and the wind speed range may be a wind speed range set when the air supply device was last started. For example, the air speed gear is switched to the "middle gear" when the air supply device is started the last time, and the air supply device is started by default at the "middle gear" when the air supply device is started the next time.
Step S2 includes S21 to S22.
Step S21: the controller 13 obtains a corresponding rotating speed group according to the current pipe diameter of the air inlet pipe, and the step S22 is performed;
step S22: the controller 13 selects a preset rotation speed corresponding to the set wind speed gear from a rotation speed group corresponding to the pipe diameter of the current air inlet pipe according to the set wind speed gear in the starting air supply instruction, and the step S3 is performed.
For example, the pipe diameter of the current air inlet pipe is d1, and the set wind speed gear is the middle gear. The controller 13 obtains a rotation speed group a corresponding to the pipe diameter d1 when executing step S21, and selects a preset rotation speed a3 from the rotation speed group a when executing step S22, where the preset rotation speed a3 is a preset rotation speed to be executed by the fan in step S3.
The multiple wind speed gears are set, so that a user can set the air supply speed of the air supply device independently, and meanwhile, at least one wind speed gear has a trend that all preset rotating speeds corresponding to the preset wind speed gears are reduced along with the increase of the pipe diameter corresponding to the rotating speed group where the wind speed gear is located, so that the problems that the current pipe diameter of the air inlet pipe 2 is large, the noise is too large, and the current pipe diameter of the air inlet pipe 2 is too small, and the air outlet speed is too small can be avoided under the wind speed gears.
In another exemplary embodiment, a plurality of wind speed steps may be configured in the controller 13. The plurality of wind speed gears may be, for example, "strong gear", "high gear", "medium gear", and "low gear", respectively.
The controller 13 is also provided with a base rotational speed group and a plurality of variation groups. The basic rotating speed group corresponds to an air inlet pipe 2 with one pipe diameter, which can be connected with an air inlet interface 11, the number of the variable quantity groups is the same as the number of the air inlet pipes 2 with the other pipe diameters, and the variable quantity groups correspond to the air inlet pipes 2 with the other pipe diameters one by one.
The basic rotating speed group is provided with a plurality of preset rotating speeds, the number of the preset rotating speeds in the basic rotating speed group is the same as that of the wind speed gears, and the plurality of preset wind speeds correspond to the wind speed gears one by one.
A plurality of variable quantities are arranged in each variable quantity group, the number of the variable quantities in each variable quantity group is the same as that of the wind speed gears, and the variable quantities correspond to the wind speed gears one by one. The variation may be a positive value or a negative value.
For example, the pipe diameters of the air inlet pipe 2, to which the air inlet port 11 can be mounted, are d1, d2, and d3, respectively, where d1< d2< d3. The pipe diameter that basic rotational speed group corresponds is pipe diameter d1, and the rotational speed of predetermineeing that contains in the basic rotational speed group is a1, a2, a3, a4 respectively, and a1> a2> a3> a4. The corresponding relations between the preset rotating speeds and the wind speed gears are as follows: the "strong gear" corresponds to a preset rotation speed a1 in the rotation speed group a, the "high gear" corresponds to a preset rotation speed a2 in the rotation speed group a, the "medium gear" corresponds to a preset rotation speed a3 in the rotation speed group a, and the "low gear" corresponds to a preset rotation speed a4 in the rotation speed group a.
The plurality of variation sets are respectively a variation set B and a variation set C. The pipe diameter d2 of the air inlet pipe 2 corresponds to the variable quantity group B; the pipe diameter d3 of the air inlet pipe 2 corresponds to the variable quantity group C.
The variation groups B include variations Δ B1, Δ B2, Δ B3, and Δ B4, respectively, and Δ B1> Δ B2> Δ B3> Δ B4. The corresponding relation between the wind speed gear and the variable quantities is as follows: the "strong gear" corresponds to the variation Δ B1 in the rotation speed group B, the "high gear" corresponds to the variation Δ B2 in the rotation speed group B, the "medium gear" corresponds to the variation Δ B3 in the rotation speed group B, and the "low gear" corresponds to the variation Δ B4 in the preset rotation speed group B.
The variation groups C include variations Δ C1, Δ C2, Δ C3, and Δ C4, respectively, and Δ C1> Δ C2> Δ C3> Δ C4. The corresponding relation between the wind speed gear and the variable quantities is as follows: the "strong gear" corresponds to the variation Δ C1 in the rotation speed group C, the "high gear" corresponds to the variation Δ C2 in the rotation speed group B, the "middle gear" corresponds to the variation Δ C3 in the rotation speed group C, and the "low gear" corresponds to the variation Δ C4 in the preset rotation speed group C.
In step S1, the start air blowing command includes information of a set wind speed gear. For example, when the user sends an air supply start instruction to the controller 13 via a remote controller or a mobile terminal, the remote controller selects a wind speed gear as a set wind speed gear to be added to the air supply start instruction, and the wind speed gear may be a wind speed gear set when the air supply device was last started. For example, the air speed gear is switched to the "middle gear" when the air supply device is started the last time, and the air supply device is started by default at the "middle gear" when the air supply device is started the next time.
Step S2 includes S21a to S26a.
Step S21a: the controller 13 determines whether the current pipe diameter of the air inlet pipe is the pipe diameter corresponding to the basic rotating speed group, if so, the step S22a is performed, otherwise, the step S23a is performed;
step S22a: the controller 13 sets a wind speed gear according to the start-up wind supply instruction, acquires a preset rotating speed corresponding to the set wind speed gear from the basic rotating speed group, and takes the preset rotating speed as a preset rotating speed to be executed by the fan, and then the step S3 is performed;
step S23a: the controller 13 obtains a preset rotation speed corresponding to the set wind speed gear from the basic rotation speed group according to the set wind speed gear, and the step S24a is entered;
step S24a: the controller 13 obtains the variation set corresponding to the current pipe diameter of the air inlet pipe according to the current pipe diameter of the air inlet pipe, and the step S25a is performed;
step S25a: the controller 13 sets a wind speed gear according to the starting air supply instruction, and obtains the variable quantity corresponding to the set wind speed gear from the variable quantity group;
step S26a: and adding the variable quantity and the preset rotating speed to obtain the preset rotating speed to be executed by the fan, and entering the step S3.
The preset rotation speed to be executed by the fan is the rotation speed of the controller 13 driving the fan to rotate in step S3.
In this way, if the pipe diameter of the current air inlet pipe is the pipe diameter corresponding to the basic speed group, the preset speed corresponding to the set wind speed gear in the basic speed group is directly adopted as the preset speed to be executed by the fan in step S3. If the current pipe diameter of the air inlet pipe is the pipe diameter corresponding to the variation group, acquiring the variation corresponding to the set wind speed gear in the variation group and the preset rotating speed corresponding to the set wind speed gear in the basic rotating speed group, and then adding the preset rotating speed and the variation to obtain the preset rotating speed to be executed by the fan in the step S3.
For example, when the pipe diameter of the current air inlet pipe is d1 and the set wind speed gear is "middle gear", the controller 13 first determines whether the pipe diameter d1 of the current air inlet pipe is the pipe diameter corresponding to the basic rotational speed group, and after the controller 13 determines that the pipe diameter d1 is the pipe diameter corresponding to the basic rotational speed group, obtains the preset rotational speed a3 corresponding to the "middle gear" from the basic rotational speed group, and uses the preset rotational speed a3 as the preset rotational speed to be executed by the fan.
And when the pipe diameter of the current air inlet pipe is d2 and the set wind speed gear is "high", the controller 13 linearly judges whether the pipe diameter d2 of the current air inlet pipe is the pipe diameter corresponding to the basic rotation speed group, when the controller 13 determines that the pipe diameter d2 is not the pipe diameter corresponding to the basic rotation speed group, a preset rotation speed a2 corresponding to the "high" is firstly obtained from the basic rotation speed group, a variation delta B2 corresponding to the "high" is obtained from a variation group B corresponding to the pipe diameter d2, then the sum of the preset rotation speed a2 and the variation delta B2 is calculated, and the calculation result is used as the preset rotation speed to be executed by the fan.
All the preset rotating speeds corresponding to at least one wind speed gear have a trend of decreasing along with the increase of the pipe diameter corresponding to the rotating speed group in which the rotating speed gear is positioned. In the present embodiment, there is at least one of the following configurations: the preset rotation speed corresponding to the "power gear" has a tendency to decrease, a1> (a 1+ Δ b 1) > (a 1+ Δ c 1), or a1> (a 1+ Δ b 1) = (a 1+ Δ c 1), or a1= (a 1+ Δ b 1) > (a 1+ Δ c 1); the preset rotation speed corresponding to the "high gear" has a tendency to decrease, for example, a2> (a 2+ Δ b 2) > (a 2+ Δ c 2), or a2> (a 2+ Δ b 2) = (a 2+ Δ c 2), or a2= (a 2+ Δ b 2) > (a 2+ Δ c 2); the preset rotation speed corresponding to the "middle gear" has a tendency to decrease, for example, a3> (a 3+ Δ b 3) > (a 3+ Δ c 3), or a3> (a 3+ Δ b 3) = (a 3+ Δ c 3); the preset rotation speed corresponding to the "low gear" has a tendency to decrease, for example, a4> b4> c4, or a4> b4= c4, or a4= b4> c4.
The multiple wind speed gears are arranged, so that a user can set the air supply speed of the air supply device independently, and meanwhile, at least one preset rotating speed corresponding to one wind speed gear has a trend of decreasing along with the increase of the pipe diameter corresponding to the rotating speed group in which the preset rotating speed gear is located, so that the problems that the current air inlet pipe 2 is large in pipe diameter and causes overlarge noise and the current air inlet pipe 2 is small in pipe diameter and causes an undersize air outlet speed can be avoided under the wind speed gears.
