Detailed Description
Hereinafter, the first to fourth embodiments will be described in detail with reference to the accompanying drawings.
(first embodiment)
A first embodiment provides a control method of an air blowing device, and as shown in fig. 1 and 2, an air blowing device 1 to which the control method is applied includes: a circulating air-blowing part 11 for circulating and blowing indoor air, and a temperature detecting part 12 for detecting indoor environment temperature.
The air blower 1 can blow not only cold air but also hot air, and the following description will take as an example an air blower with a heating unit 14 and capable of blowing hot air.
The control method comprises the following steps: as shown in fig. 3, the temperature control method for controlling the operation state of the air blowing device 1 according to the detected ambient temperature includes the steps of:
controlling the operation state of the air supply device 1 according to the detected ambient temperature, specifically comprising the following substeps:
s301, calculating the average temperature of a plurality of ambient temperatures T detected in the first time D1And
s302, according to the set target temperature X and the average temperature
And controls the operation state of the air blowing device 1.
The circulating air supply part 11 includes an indoor air inlet 111, a snail shell, a fan blade, a motor, an indoor air outlet 112 and an air guide part 113.
The indoor air inlet 111 is arranged on the basket body of the air supply device 1 and communicated with the snail shell and the opening of the indoor space, so that indoor air enters the snail shell.
The snail shell comprises parallel rolling plates and side plates connected with the rolling plates, and the rolling plates and the side plates form an air path for air to pass through.
And the fan blades are arranged in the snail shells, and rotate to suck indoor air into the snail shells from the indoor air inlets 111 and blow the indoor air out of the indoor air outlets 112. In this embodiment, the fan blades are centrifugal fan blades.
And the motor is arranged on the snail shell, so that the fan blades rotate, and the rotating speed of the fan blades is changed by changing the rotating speed of the motor, so that the air speed and the air volume of the air supply device 1 are adjusted.
And an indoor air outlet 112, which is arranged on the basket body of the air supply device 1 and is communicated with the snail shell and the opening of the indoor space, so that the air in the snail shell is blown out to the indoor space.
And an air guide part 113 provided at the indoor air outlet 112 and rotating to change an angle of the blown air.
As a result, the indoor air is sucked into the air blowing device 1 through the circulating air blowing unit 11 and blown into the room again, thereby realizing circulating air blowing of the indoor air. Specifically, under the action of the rotation of the fan blades, indoor air enters the snail shell from the indoor air inlet 111, and is blown to the indoor air outlet 112 through the air path formed by the snail shell, and finally is blown to the indoor.
The heating portion 14 includes a heating portion 14 provided on the downstream side of the fan blade and located between the fan blade and the indoor air outlet 112. The air sucked into the snail shell is heated by the heating part 14 and then blown to the indoor space through the indoor air outlet 112, thereby heating the indoor air.
The heating part 14 includes at least one PTC (positive temperature coefficient thermistor) heating unit, each of which can be independently switched. The heating amount of the heating portion 14 is adjusted by controlling the ON/OFF state of the heating unit.
The combination of the wind speed of the circulating air-blowing part 11 and the heating amount of the heating part 14 allows the air-blowing device 1 to blow wind of different temperatures, that is, the circulating air-blowing part 11 generates different wind speeds and the heating part 14 generates different heating amounts, so that the combination of the wind speed and the heating amount can be set to any number of stages. The air supply device 1 works at different gears and can blow out air with different temperatures.
Specifically, the greater the heating amount of the heating portion 14, the higher the temperature of the air blown out by the air blowing device 1, and conversely, the lower the temperature of the air blown out by the air blowing device 1. Meanwhile, when the heating amount of the heating unit 14 is not changed, the higher the wind speed of the circulating air-blowing unit 11 is, the lower the temperature of the wind blown by the air blowing device 1 is, and vice versa.
The gear positions may be arranged according to the temperature of the wind blown out by the wind blowing device 1, for example, the gear positions are arranged in order from low to high according to the temperature of the wind blown out by the wind blowing device 1, that is, the gear positions are smaller when the temperature of the wind blown out by the wind blowing device 1 is lower, and vice versa. Similarly, the gears may be sorted in reverse, so that the lower the temperature of the air blown by the air supply device 1, the larger the gears are, and the sorting is rare, so the present invention preferably sorts the gears in sequence.
The temperature detection section 12 includes a temperature sensor provided on the upstream side of the heating section 14. The temperature sensor is disposed in the indoor air inlet 111 and is configured to detect a temperature of air sucked into the indoor air inlet 111, i.e., detect a current ambient temperature in real time.
In step S301, the average temperature is obtained by averaging a plurality of ambient temperatures detected by the temperature detection unit 12 within the first time period D1
The first time D1 is a time required for the air guide portion 113 provided at the indoor air outlet 112 of the air blowing device 1 to rotate 1 × N cycles (N is a positive integer).
When N is 1, the air guiding part 113 rotates once within the first time D1, the temperature detecting part 12 detects and obtains a number of values of the ambient temperature T within the time D1, and the control part 13 calculates the average temperature of the a number of the ambient temperatures TThen according to the set target temperature X and the average temperature
And controlling the air supply device 1 to maintain the current operation gear, or to reduce the current operation gear, or to increase the current operation gear.
For example, the time D1 required for the wind guide portion 113 to rotate once (the maximum angle at which the wind guide portion 113 can rotate) is 25 seconds. When the time required for the temperature detection unit 12 to detect and obtain one current ambient temperature value is 1 second, 25 current ambient temperature T values, which are T1 ', T2', T3
Target temperature X and average temperatureDifference of (2)
The time unit is a time when the temperature sensor detects an ambient temperature T, and for convenience of understanding, the time unit is defined as, but not limited to, seconds. Note that the control unit 13 in step S301 calculates the average temperature without interruption
That is, when the blower 1 is turned on for the 26 th second, the average temperature of the ambient temperature obtained in the first 25 seconds is calculated
Calculating the average value of the detected ambient temperature T from the 1 st second to the 25 th second; when the blower 1 is turned on for the 27 th second, the average temperature of the ambient temperature obtained in the first 25 seconds is calculated
I.e., the average value of the ambient temperatures T detected from the 2 nd to 26 th seconds. Thereby, the control unit 13 obtains a plurality of average temperatures without interruption
The value of (c).
In step S302, the target temperature X and the average temperature are compared
And comparing the difference delta T with four preset temperature values, namely a first temperature (T1), a second temperature (T2), a third temperature (T3) and a fourth temperature (T4), and controlling the operation state of the air supply device 1, wherein T1 is more than T3 and less than T4 and more than T2.
The operation state of the air blowing device 1 includes: the currently operating gear is maintained, lowered (the current gear is sequentially lowered by one gear), or raised (the current gear is sequentially raised by one gear). The 6 shift speeds (first, second, third, fourth, fifth, and sixth shift speeds) are exemplified for explanation. In addition, even when the blower device 1 is in the minimum gear (first gear), the heating amount is still greater than 0, i.e., at least one heating unit is in the ON (ON) state.
When Δ T is less than or equal to T1, the air blowing device 1 is operated at the minimum gear (first gear), that is, at the minimum heating amount of the heating part 14 and the minimum air speed of the circulating air blowing part 11;
when Δ T > T2, the blower 1 is operated at the maximum gear (sixth gear), that is, at the maximum heating capacity of the heating unit 14 and the maximum wind speed of the circulating blower unit 11;
when T1 is more than delta T and less than or equal to T3, the air supply device 1 is operated by reducing the gear from the current operation state, namely, the heating quantity of the heating part 14 is reduced and the air speed of the circulating air supply part 11 is reduced, or the air speed of the circulating air supply part 11 is increased when the heating quantity of the heating part 14 is unchanged;
when T3 is more than or equal to DeltaT and less than or equal to T4, the air supply device 1 maintains the current operation state, namely the current heating quantity of the heating part 14 and the current air speed operation of the circulating air supply part 11 are maintained;
when T4 < Δ T ≦ T2, the air blower 1 is operated from the current operation state by increasing the gear, i.e., increasing the heating amount of the heating unit 14 and the air speed of the circulating air-supplying unit 11, or decreasing the air speed of the circulating air-supplying unit 11 when the heating amount of the heating unit 14 is not changed.
In order to prevent the service life of the heating unit from being shortened due to frequent gear shifting of the air supply device 1, it is preferable that the operation state of the air supply device 1 is maintained for a second time D2 after the operation state is changed. For example, when D2 is 120s, after the blower device 1 is switched from the first state to the second gear, the blower device 1 should maintain the second gear 120s, and after that, the second gear can be changed to another gear.
The following describes a control method of the air blowing device 1 with reference to a control flowchart of the air blowing device shown in fig. 4:
step S41: the circulating air supply part 11 and the heating part 14 of the air supply device 1 are opened;
step S42: the temperature detection unit 12 continuously detects the current ambient temperature T;
step S43: the temperature control method calculates an average temperature of the ambient temperature T detected during the first time D1
Step S44: the temperature control method calculates a target temperature X and an average temperature
The value of the difference Δ T;
step S45: comparing the delta T with the first temperature, the second temperature, the third temperature and the fourth temperature by using the temperature control method, and entering S45-1 when the delta T is less than or equal to the first temperature; when the delta T is larger than the second temperature, S45-2 is entered; when the first temperature is less than delta T and less than or equal to the third temperature, S45-3 is carried out; when the third temperature is less than delta T and less than or equal to the fourth temperature, S45-4 is carried out; when the fourth temperature is less than delta T and less than or equal to the second temperature, S45-5 is carried out;
step S45-1: the temperature control method controls the heating unit 14 to operate at the minimum heating amount and controls the circulating air-feeding unit 11 to operate at the minimum air speed, and the process proceeds to S46;
step S45-2: the temperature control method controls the heater 14 to operate at the maximum heating amount and controls the circulating air-feeding unit 11 to operate at the maximum air speed, and the process proceeds to S46;
step S45-3: the temperature control method is executed based on the current operation state, and the amount of heating by the heater 14 and the air speed of the circulating air-feeding unit 11 are reduced, or the air speed of the circulating air-feeding unit 11 is increased while the heater 14 is maintained, and the process proceeds to S46;
step S45-4: the temperature control method maintains the current running state, and the step enters S46 after the execution;
step S45-5: the temperature control method is executed after increasing the heating amount of the heating unit 14 and the air speed of the circulating air-feeding unit 11 based on the current operation state, or decreasing the air speed of the circulating air-feeding unit 11 while the heating unit 14 is maintained, and the process proceeds to S46;
step S46: judging whether or not the heating amount of the heating unit 14 and the wind speed of the circulating air-feeding unit 11 have changed, i.e., not changed, and returning to S45; the change is made, and the process proceeds to S47;
step S47: the temperature control method controls the air supply device 1 to maintain the current operation state within the time D2.
Therefore, the present invention controls the operation state of the air supply device 1 by the difference between the target temperature and the average temperature, reduces the influence of the rotation of the air guide part 113 and the unstable hot air blown out from the indoor air outlet 112, can maintain the environmental temperature consistent with the target temperature, and realizes the start-up stage of the air supply device 1.
(second embodiment)
A second embodiment provides a control method of an air supply device including:
a circulating air supply part for circulating air supply of indoor air;
a detection unit for detecting an indoor ambient temperature;
and a control unit for controlling the operation state of the air supply device according to the detected ambient temperature.
The control method comprises the following steps:
in the starting stage, the environment temperature is consistent with the set target temperature within the preset time; and
a constant temperature phase, maintaining the difference between the ambient temperature and the target temperature within a predetermined range.
Specifically, in the start-up phase, a reference value Y, that is, a value of the ambient temperature detected before the third time D3 at the present time is preset.
D3 may take 15s, that is, the ambient temperature measured by the temperature sensor 15s before the current time is Y. For example, when the blower is turned on for 20 seconds, the reference value Y used for comparison has a value of the ambient temperature Ta detected at the time of turning on for 5 seconds. And the control method continuously detects the ambient temperature T, for example, when the air supply device is started for 21 seconds, the value of the reference value Y is the value of the ambient temperature Tb detected when the air supply device is started for 6 seconds. By analogy, in the start-up phase, the control method will continuously update the assignment of the reference value Y with the update of the value of the ambient temperature T.
After the reference value Y is obtained, determining that the difference Z between the reference value Y and the target temperature X is Y-X, if Z is more than or equal to 2, the air supply device is in a constant temperature stage, and in the constant temperature stage, the air supply device is continuously controlled by using the control method of the first embodiment; if Z is less than 2, the air supply device continues to stay at the starting stage.
(third embodiment)
A third embodiment provides an air supply device 1, the air supply device 1 including:
a circulating air supply part 11 for circulating and supplying air to the indoor air;

The air blowing device 1 can blow not only cold air but also hot air, and the air blowing device 1 in this embodiment is provided with a heating portion 14 and can blow out hot air.
As shown in fig. 1 and 2, the circulating air supply part 11 includes an indoor air inlet 111, a snail shell, fan blades, a motor, an indoor air outlet 112, and an air guide part 113; the heating unit 14 is disposed between the downstream side of the fan blades and the indoor air outlet 112, and includes at least one PTC heating unit, and each PTC heating unit can be independently turned on and off. The heating amount of the heating portion 14 is adjusted by controlling the on-off state of the heating unit; the temperature detection unit 12 includes a temperature sensor provided upstream of the heating unit 14, and the temperature sensor is provided in the indoor air inlet 111 to detect the current ambient temperature in real time.
The information receiving unit of the control unit 13 receives the ambient temperatures in the plurality of D1 measured by the temperature detecting unit 12; the temperature calculation part averages the temperature to obtain an average temperature; the temperature comparing unit calculates a difference Δ T between the target temperature stored in the information storage unit and the average temperature, and the control unit 13 can thereby control the operation state of the air blowing device 1 based on Δ T. The operation state of the air blowing device 1 includes: the currently operating gear is maintained, lowered (the current gear is sequentially lowered by one gear), or raised (the current gear is sequentially raised by one gear).
The heating units in different on-off states provide different heating amounts for the indoor air, and the different rotating speeds of the motor of the circulating air supply part 111 provide different wind speeds for the indoor air, so that the air supply device 1 works at different gears to blow out wind with different temperatures. Specifically, the greater the heating amount of the heating portion 14, the higher the temperature of the air blown out by the air blowing device 1, and conversely, the lower the temperature of the air blown out by the air blowing device 1. Meanwhile, when the heating amount of the heating unit 14 is not changed, the higher the wind speed of the circulating air-blowing unit 11 is, the lower the temperature of the wind blown by the air blowing device 1 is, and vice versa.
In order to control the operation state of the air supply device 1, the target temperature X and the average temperature are set
The difference delta T is compared with four preset temperature values, namely a first temperature (T1) to a fourth temperature (T4), wherein T1 is more than T3 and less than or equal to 0 and more than T4 and more than T2.
When the delta T is less than or equal to T1, the air supply device 1 is operated at the minimum gear, namely, the minimum heating quantity of the heating part 14 and the minimum wind speed of the circulating air supply part 11 are operated;
when Δ T > T2, the blower 1 is operated at the maximum gear, that is, at the maximum heating capacity of the heating part 14 and the maximum wind speed of the circulating blower 11;
when T1 is more than Delta T and less than or equal to T3, the air supply device 1 is operated by one gear from the current operation state, namely, the heating quantity of the heating part 14 is reduced and the air speed of the circulating air supply part 11 is reduced, or the air speed of the circulating air supply part 11 is increased when the heating quantity of the heating part 14 is unchanged;
when T3 is more than or equal to DeltaT and less than or equal to T4, the air supply device 1 maintains the current operation state, namely the current heating quantity of the heating part 14 and the current air speed operation of the circulating air supply part 11 are maintained;
when T4 < Δ T ≦ T2, the air blower 1 is operated by one gear from the current operation state, i.e., the current heating amount of the heating unit 14 and the current air speed of the circulating air-supplying unit 11 are increased, or the air speed of the circulating air-supplying unit 11 is decreased when the heating amount of the heating unit 14 is not changed.
In addition, in order to prevent the service life of the heating unit from being shortened due to frequent gear shifting of the air supply device 1, the operation state of the air supply device 1 is maintained during a second time D2 after the operation state is changed; after D2, its operating state may be changed.
Accordingly, the operation state of the air blowing device 1 is controlled by the difference between the target temperature and the average temperature, the influence of the rotation of the air guide part 113 and the unstable hot air blown out from the indoor air outlet 112 is reduced, and the environmental temperature can be maintained to be the same as the target temperature.
The air supply device 1 can work in an opening stage and a constant temperature stage.
The control section 13 may further include: a reference section for recording a reference value Y to be compared with the Δ T; and a determination unit that determines whether or not to change the operation state of the air blower 1 based on a comparison result between the reference value Y and the Δ T.
In the constant temperature phase, the reference unit presets a reference value Y, i.e., the value of the ambient temperature detected at the present time before the third time D3.
D3 may take 15s, that is, the ambient temperature measured by the temperature sensor 15s before the current time is Y. For example, when the blower 1 is turned on for 20 seconds, the reference value Y used for comparison has a value of the ambient temperature Ta detected at the time of turning on for 5 seconds. And the control method continuously detects the ambient temperature T, namely when the air supply device 1 is started for 21 seconds, the value of the reference value Y is the value of the ambient temperature Tb detected and obtained when the air supply device is started for 6 seconds. By analogy, in the start-up phase, the control method will continuously update the assignment of the reference value Y with the update of the value of the ambient temperature T.
After obtaining the reference value Y, the determination part determines that the difference Z between the reference value Y and the target temperature X is Y-X, and if Z is larger than or equal to 2, the air supply device 1 is controlled to be in a constant temperature stage; if Z is less than 2, the air supply device 1 is controlled to stay at the starting stage.
It should be noted that the control unit 13 may be located inside the air supply device 1 as shown in fig. 2, and the control unit 13 may also be a mobile device outside the air supply device 1, where the mobile device includes, but is not limited to, a mobile phone, a computer, and a remote controller, and may communicate with the air supply device 1 in a wired or wireless manner, so as to control the operation state of the air supply device 1.
