Fig. 1 is the schematic diagram illustrating according to the dehumidification type air purifier of the first embodiment of the present invention.
With reference to figure 1, according to the dehumidification type air purifier 100 of one embodiment of the invention, can comprise filter element 110, Dehumidifying element 120, supply fan 130, sensor unit S1, S2, S3 and controller 140.Here, the path P shown in Fig. 1 represents to be introduced into the air path of dehumidification type air purifier 100.The air being introduced into can pass filter element 110 and Dehumidifying element 120 subsequently.
With reference to Fig. 1, describe according to the dehumidification type air purifier 100 of one embodiment of the invention.
Filter element 110 can filter out and be contained in the airborne pollutant being introduced into wherein.Filter element 110 can remove this pollutant, makes it absorb the airborne pollutant of being introduced by supply fan 130.
Filter element 110 can be divided into the first filter element 111 and the 112 and second filter element 113 and 114.Each filter element can comprise a plurality of filters.
Particularly, the first filter element 111 and 112 can comprise prefilter 111, functional filter 112 etc., and the second filter element 113 and 114 can comprise high efficiency particle, catches air (HEPA) filter 113, odor removal filter 114 etc.
Prefilter 111 can be used for removing relatively large dust micronic dust, pet hair etc., and functional filter 112 can be used for removing pollen, mouse acarid, harmful microorganism, bacterium, Huang Chen etc.Here, except by the function filtering out containing aerial pollutant, functional filter can be carried out various other functions, and can comprise the vitamin filter etc. that vitamin ingredients is incorporated into the air of discharge.
In addition, filter element 110 can comprise various types of filters and be not limited to the filter of quantity shown in Fig. 1.
Dehumidifying element 120 can remove being contained in introduced airborne steam.Dehumidifying element 120 can adopt cooling introduced air to reduce the cooling scheme of quantity of steam that may be with which.
Particularly, Dehumidifying element 120 can comprise and evaporates the evaporimeter of liquid refrigerant, the compressor 122 of the gaseous refrigerant that evaporated by evaporimeter 121 of compression and the condenser 123 that the condensation of refrigerant of being compressed by compressor 122 is recirculated to evaporimeter 121, and adjust the airborne humidity of introducing.
Operation principle for Dehumidifying element 120, when evaporimeter 121 flashes to gaseous refrigerant by liquid refrigerant, the heat of surrounding environment is absorbed with cool ambient air, and compressor 122 sucks the gaseous refrigerant being evaporated by evaporimeter 121 and makes this cold-producing medium bring up to saturation pressure and discharge this cold-producing medium.Thus, when cold-producing medium passes compressor 122, cold-producing medium becomes has high-temperature and high pressure.And condenser 123 allows the high temperature and high pressure cold-producing medium having been compressed by compressor 122 and has the surrounding air heat exchange of relative low temperature degree and be condensed to have room temperature and high pressure, thus liquefaction again.Thus, the cold-producing medium of this liquefaction is discharged to have than the lower temperature of normal condensation temperature and from condenser 123 by sub-cooled.
Meanwhile, thereby the liquid refrigerant of discharging from condenser 123 passes expansion valve (not shown) to have low pressure in the state of evaporation wherein can easily occur, and low-pressure, liquid refrigerant is recirculated to evaporimeter 121 with cooling evaporator 121 ambient airs.In this process, containing aerial steam be condensed (or condensing) on the surface of evaporimeter 121 and by drain hose (not shown), discharge to reduce airborne humidity.In this way, by containing the Dehumidifying element 120 of evaporimeter 121, compressor 122 and condenser 123, air is discharged to room area by evaporimeter 121 and condenser 123, and room air guided to evaporimeter 121 again, and this cyclic process is repeated to carry out so that room area is dehumidified.Here, compressor 122 can be by carrying out compressed refrigerant with motor, and compressor is that the operation of motor can be controlled by controller 140.
Supply fan 130 by revolution extraneous air is introduced to the inside of dehumidification type air purifier 100.Particularly, as shown in the figure, the air of introducing by supply fan 130 is through filter element 110 and Dehumidifying element 120.The motor of rotating inlet fan 130 can be another motor that is different from the motor that moves compressor 122.The rotary speed of supply fan 130 (or speed of rotation) can be controlled by controller 140, and the extraneous air amount that is introduced into dehumidification type air purifier can change according to rotary speed.
Dehumidification type air purifier 100 can move under the purification pattern of not using Dehumidifying element 120 by removing airborne pollutant with filter element 110, or is moving by removing with Dehumidifying element 120 under the dehumidification mode of airborne steam.Here, the rotary speed of supply fan 130 can change according to the pattern of dehumidification type air purifier 100, and particularly, when dehumidification type air purifier 100 moves under purification pattern, the higher rotary speed operation of rotary speed that it can be when moving under common dehumidification mode than this dehumidification type air purifier 100.
For example, the rotary speed of the supply fan 130 under purification pattern can be set in the scope of about 300rpm to 1000rpm, and supply fan 130 can have scope from the rotary speed of 400rpm to 650rpm.The wet-out property of Dehumidifying element 120 can change according to the amount that is provided to the extraneous air of Dehumidifying element 120, and if extremely little or extremely large extraneous air amount be provided to Dehumidifying element 120, the wet-out property of this this Dehumidifying element 120 may reduce greatly.Thus, when dehumidification type air purifier 100 moves under dehumidification mode, compare with purification pattern, the rotary speed of supply fan 130 can be set in narrower range.
Purification pattern can comprise normal purification pattern and functional purification pattern, in normal purification pattern, the airborne pollutant that the rotary speed of supply fan 130 is set according to the desired air-flow power of user (or tolerance) and introduced by supply fan 130 is removed by filter element 110, in functional purification pattern, supply fan 130 moves according to the rotary speed of supply fan 130, and this rotary speed is to set to carry out corresponding function according to corresponding function.This functional purification pattern can be such as comprising yellow dirt pattern, cloth drying pattern, nighttime sleep pattern etc.
In yellow dirt pattern situation, the rotary speed of supply fan 130 can be configured to remove rapidly and be introduced into the yellow dirt in room area and be contained in the noxious material such as each heavy metal species, harmful microorganism etc. in this Huang dirt.That is, in yellow dirt pattern situation, the rotary speed of supply fan 130 is configured to height, thus rapid moving depollution thing.On the contrary, for user, about dehumidification type air purifier 100, nighttime sleep pattern requires quiet, and therefore according to the operation of dehumidification type air purifier 100, supply fan 130 is configured to have low rotary speed, thereby produces a small amount of noise.That is,, for the functional purification pattern of correspondence, the rotary speed of supply fan 130 can suitably be set in advance according to aforesaid corresponding function.
And dehumidification type air purifier 100 can move under automatic mode.; for example, when airborne humidity surpasses humidity datum-plane (50%) and dehumidification type air purifier 100 while moving under purification pattern; dehumidification type air purifier 100 can become under dehumidification mode and moves; afterwards; when humidity is reduced to humidity datum-plane lower time; according to the dehumidifying operation of Dehumidifying element 120, dehumidification type air purifier 100 can become under purification pattern and moves.
In addition, the rotary speed of supply fan 130 is to control according to the corresponding function of being carried out by controller 140.Particularly, this rotary speed can be dried with respect to the control of air-flow power, defrosting, heat exchange, overload is controlled and compression startup reducing noise is controlled to set.Below will specific algorithm that set the rotary speed of supply fan 130 according to corresponding function be described.

According to the previous constructions shown in Fig. 1, filter element 110 and Dehumidifying element 120 separate, thereby dehumidification type air purifier 100 has the technique effect that can easily assemble and manage.In addition,, because HEPA filter 113 is positioned at the previous stage of Dehumidifying element 120 in path P, can prevent that the dust in the heat exchanger 121 and 123 of Dehumidifying element 120 from gathering.
Fig. 2 is the schematic diagram that dehumidification type air purifier is according to a second embodiment of the present invention shown.With reference to figure 2, unlike dehumidification type air purifier 100, dehumidification type air purifier 200 according to a second embodiment of the present invention has the structure that the first filter element 110A and the second filter element 110B is separated based on Dehumidifying element 120.Thus, the air of being introduced by supply fan 130 is subsequently through the first filter element 110A, Dehumidifying element 120 and the second filter element 110B, as indicated in path P.Particularly, because odor removal filter 114 is arranged in the rear one-level place of Dehumidifying element 120, as shown in path P, at the heat exchanger 121 and 123 by Dehumidifying element 120, remove after stink, air is discharged from.Thus, the dehumidification type air purifier 100 than Fig. 1, can obtain better room air by dehumidification type air purifier 200.And, because odor removal filter 114 is arranged in before HEPA filter 113, as shown in path P, can prevent that HEPA filter 113 from being permeated by stink.In addition, because HEPA filter 113 is arranged in the rear one-level of Dehumidifying element 120, the dry air after dehumidifying can pass HEPA filter 113, realizes the technique effect of the hydraulic performance decline that prevents HEPA filter 113, especially during summer.
Fig. 3 is the schematic diagram that the dehumidification type air purifier of a third embodiment in accordance with the invention is shown.Dehumidification type air purifier 200 unlike Fig. 2, the dehumidification type air purifier 300 of Fig. 3 has the wherein heat exchanger 121 and 130 of Dehumidifying element 120 and is arranged in perpendicular to the structure in the plane of path P, and the air of being introduced by supply fan 130 is discharged from along path P.Meanwhile, the dehumidification type air purifier 200 of similar Fig. 2, based on Dehumidifying element 120, makes the first filter element 110A and the second filter element 110B120 separately, obtains above with reference to the described same advantage of Fig. 2.
Fig. 4 is the schematic diagram that the dehumidification type air purifier of a fourth embodiment in accordance with the invention is shown.Dehumidification type air purifier 100 unlike Fig. 1, the dehumidification type air purifier 400 of Fig. 4 has wherein condenser 121 and the evaporimeter 123 of Dehumidifying element 120 and is arranged in perpendicular to the structure in the plane of path P, and the air of being introduced by supply fan 123 is discharged from along path P.Meanwhile, the dehumidification type air purifier 100 of similar Fig. 1, comprises that the first filter element 110 of the first filter element 110A and the second filter element 110B is arranged in the previous stage of Dehumidifying element 120, obtains above with reference to the described same advantage of Fig. 1.
Fig. 5 be according to one embodiment of the invention for controlling the flow chart of process of the method for dehumidification type air purifier, wherein, particularly, by using the illumination value of being measured by illumination sensor S3 to control dehumidification type air purifier.Certainly, with reference to the described control method of figure 5, can be applicable to have all devices of the previous constructions shown in Fig. 1 to 4.
Referring to figs. 1 to 5, first, sensor unit S1, S2 and S3 measure illumination value L0, humidity value H0 and Dust Capacity D0(S500).The illumination value L0 measuring, humidity value H0 and Dust Capacity D0 are passed to controller 140.
Next, controller 140 compares (S501) by the illumination value L0 measuring and reference illumination L1.According to comparative result, when the illumination value L0 measuring is equal to or greater than reference illumination L1, controller 140 is determined to be daytime and to perform step S502, and when the illumination value L0 measuring is less than reference illumination L1, and controller 140 is determined to be night and to perform step S505.Here, reference illumination L1 is the illumination value as the benchmark for definite daytime and night.
In step S502, controller 140 compares the humidity value H0 measuring and reference humidity H1.According to comparative result, when the humidity value H0 measuring is equal to or greater than reference humidity H1, controller 140 determines that humidity value is high and performs step S503, and at the humidity value H0 measuring, is less than under the situation of reference humidity H1 controller 140 execution step S508.
When being daytime, execution step S503 and supply fan 130 are controlled in having high humidity level environment.Particularly, controller 140 can be controlled according to the humidity value H0 measuring the rotary speed of supply fan 130, and the speed of supply fan 130 can be controlled so as to any having in default RPM value.For example, when the humidity value H0 measuring is higher than reference humidity value 30% or when higher, controller 140 is controlled supply fans 130 and is rotated with R5 rev/min of (RPM) speed.When the humidity value H0 measuring higher than reference humidity value 20% when being less than 30%, controller 140 is controlled supply fans 130 and is rotated with R6 rev/min of (RPM) speed.When the humidity value H0 measuring higher than reference humidity value 10% when being less than 20%, controller 140 is controlled supply fans 130 and is rotated with R7 rev/min of (RPM) speed.Here, opening relationships R5>R6>R7.Particularly, at controller 140, control supply fans 130 with specific RPM(R5, one of R6 and R7) after rotation, during a period of time, for example, after 3 seconds, compressor 122 power supplies (S504) that controller 140 can be to Dehumidifying element 120.In this way, although provide (wait) during a period of time at supply fan 130 after controlling, Dehumidifying element 120 can operation after air admission unit 130 is with the RPM rotation of stable state.
Particularly, when first supply fan 130 moves and Dehumidifying element 120 while moving subsequently, the noise producing uniquely when the compressor 122 of Dehumidifying element 120 starts can be submerged in the noise being produced by supply fan 130.Then, can prevent the problem that sudden change noise and vibration that user is caused by the operation by compressor 122 is given a start.
Humidity value above (reference humidity value 10%, 20% and 30%) is only illustrative and according to an embodiment, while needing, can change in the nature of things.And in another embodiment of the present invention, first power supply can be provided to compressor 122(S504) and the rotary speed of supply fan 130 can then be controlled (S503).
Meanwhile, when being daytime, execution step S508 and supply fan 130 are controlled in having low moisture levels environment.In this situation, the power supply of controller 140 closing controllers 122.Reason is that Dehumidifying element 120 does not need operation, because the humidity value H0 measuring is less than reference humidity H1.Thus, in this situation, the rotary speed that controller 140 is controlled supply fan 130 pro rata by the Dust Capacity D0 with measuring is carried out air cleaning and is worked.For example, when the Dust Capacity H0 measuring is during higher than benchmark Dust Capacity D1, controller 140 is controlled supply fans 130 with the RPM rotation of R1.When the Dust Capacity D0 measuring declines with relative uniform rate for benchmark Dust Capacity D1, controller 140 can be controlled the RPM rotation of supply fan 130 to reduce gradually, such as from R2, and R3 and R4.Here, opening relationships R1>R2>R3>R4.
Meanwhile, when the illumination value L0 measuring is less than reference illumination L1(night for example), controller 140 is by the humidity value H0 measuring and reference humidity H1 comparison (S505).According to comparative result, when the humidity value H0 measuring is equal to or greater than reference humidity H1, controller 140 execution step S506, are less than reference humidity H1 and work as the humidity value H0 measuring, and controller 140 can perform step S507.
When being night, can perform step S506 and supply fan 130 is controlled in having high humidity level environment.In this situation, controller 140 moves Dehumidifying elements 120 and controls supply fan 130 is that R7 flows with minimum RPM speed among a plurality of RPM speed (R5 to R7) setting according to humidity value.That is, at night, user can sleep, thereby the sleep pattern of the minimum that can wherein be produced by dehumidification type air purifier is carried out dehumidifying operation.
When being night, execution step S507 and supply fan 130 are controlled in having low moisture levels environment.Controller 140 can be controlled the multistage RPM(R1 to R4 of supply fan 130 to arrange according to Dust Capacity) among minimum RPM speed be R4 operation.That is, with the sleep pattern of the minimum that wherein produced by the rotation of supply fan 130, carrying out air cleaning moves.
Meanwhile, even after the driving of Dehumidifying element 120 stops, controller 140 also can be controlled driven certain a period of time of supply fan 130.That is, for dry, remain in the steam in Dehumidifying element 120, extraneous air is provided to Dehumidifying element 120 to accelerate residual evaporation of water by supply fan 130.Particularly, if water remains in Dehumidifying element 120, remain on the surface of evaporimeter 121 grades such as water, the harmful microorganism not being removed after dehumidifying operation, mould etc. can be propagated and pollute the inside of dehumidification type air purifier and produce bad stink etc.Thus, even after Dehumidifying element 120 runs abort, controller 140 can drive 130 certain a period of time of supply fan, so that the steam remaining in Dehumidifying element 120 is removed.
As mentioned above, even when the humidity value H0 measuring is high, if the illumination value L0 measuring is less than reference illumination L1, supply fan 130 is controlled so as to such as rotating with minimum RPM speed in environment night, reduces thus noise and keeps good and comfortable indoor environment.
Fig. 6 is that wherein, this dehumidification type air purifier is moved only carries out dehumidification function according to another embodiment of the present invention for controlling the flow chart of process of the method for dehumidification type air purifier.Certainly, with reference to the described control method of figure 6, can be applicable to have all devices of the previous constructions shown in Fig. 1 to 4.
With reference to figure 6, first, sensor unit S1, S2 and S3 measure illumination value L0 and humidity value H0(S600).The illumination value L0 and the humidity value H0 that measure are passed to controller 140.
Next, controller 140 is by the illumination value L0 measuring and reference illumination L1 comparison (S601).According to comparative result, when the illumination value L0 measuring is equal to or greater than reference illumination L1, controller 140 is determined to be daytime and to perform step S602, and at the illumination value L0 measuring, is less than in the situation of reference illumination L1 controller 140 execution step S610.Here, reference illumination L1 is the illumination value as the benchmark for definite daytime and night.
In step S602, controller 140 is by the humidity value H0 measuring and reference humidity H1 comparison.According to comparative result, when the humidity value H0 measuring is equal to or greater than reference humidity H1, controller 140 determines that humidity is high and performs step S603, and at the humidity value H0 measuring, is less than in the situation of reference humidity H1 controller 140 execution step S620.
When being daytime, execution step S603 and supply fan 130 are controlled in having high humidity level environment.Particularly, controller 140 can be controlled supply fan 130 with multistage RPM(R5 to R7 according to the humidity value H0 measuring) rotation.For example, when the humidity value H0 measuring is higher than reference humidity value 30% or when higher, controller 140 is controlled supply fans 130 and is rotated with R5 rev/min of (RPM) speed.When the humidity value H0 measuring is higher than reference humidity value 20% to 30% or when following, controller 140 is controlled supply fans 130 and is rotated with R6 rev/min of (RPM) speed.When the humidity value H0 measuring higher than reference humidity value 10% when being less than 20%, controller 140 is controlled supply fans 130 and is rotated with R7 rev/min of (RPM) speed.Here, opening relationships R5>R6>R7.Particularly, at controller 140, control supply fans 130 with specific RPM(R5, one of R6 and R7) after rotation, during a period of time, for example, after 3 seconds, compressor 122 power supplies (S604) that controller 140 can be to Dehumidifying element 120.In this way, although provide (wait) during a period of time at supply fan 130 after controlling, Dehumidifying element 120 can operation after air admission unit 130 is with the RPM rotation of stable state.Humidity value above (reference humidity value 10%, 20% and 30%) is only example and according to an embodiment, while needing, can change.
Meanwhile, when being daytime, execution step S620 and supply fan 130 are controlled in having low moisture levels environment.In this situation, the power supply of controller 140 closing controllers 122.Reason is that Dehumidifying element 120 does not need operation, because the humidity value H0 measuring is less than reference humidity H1.
Meanwhile, when the illumination value L0 measuring is less than reference illumination L1(night for example), controller 140 is by the humidity value H0 measuring and reference humidity H1 comparison (S610).According to comparative result, when the humidity value H0 measuring is equal to or greater than reference humidity H1, controller 140 execution step S611, and when the humidity value H0 measuring is less than reference humidity H1, controller 140 can perform step S612.
When being night, can perform step S611 and supply fan 130 is controlled in having high humidity level environment.In this situation, it is R7 rotation with minimum RPM speed in a plurality of RPM speed (R5 to R7) of setting with respect to humidity value that controller 140 can be controlled supply fan 130.
Similarly, when being night, execution step S612 and supply fan 130 are controlled in having low moisture levels environment.In this situation, the power supply of controller 140 closing controllers 122.Reason is that Dehumidifying element 120 does not need operation, because the humidity value H0 measuring is less than reference humidity H1.
Meanwhile, even after the running abort of Dehumidifying element 120, controller 140 also can be controlled driven certain a period of time of supply fan 130.By this control, can realize the dry effect of steam remaining in Dehumidifying element 120.
Fig. 7 is that wherein, this dehumidification type air purifier is moved only carries out purification function according to another embodiment of the present invention for controlling the flow chart of process of the method for dehumidification type air purifier.Certainly, with reference to the described control method of figure 7, can be applicable to have all devices of the previous constructions shown in Fig. 1 to 4.
With reference to figure 7, first, sensor unit S1, S2 and S3 measure illumination value L0 and Dust Capacity D0(S700).The illumination value L0 and the Dust Capacity D0 that measure are passed to controller 140.
Next, controller 140 is by the illumination value L0 measuring and reference illumination L1 comparison (S701).According to comparative result, when the illumination value L0 measuring is equal to or greater than reference illumination L1, controller 140 is determined to be daytime and to perform step S702, and at the illumination value L0 measuring, is less than in the situation of reference illumination L1 controller 140 execution step S704.Here, reference illumination L1 is the illumination value as the benchmark for definite daytime and night.
In step S702, controller 140 is by the Dust Capacity D0 measuring and benchmark Dust Capacity D1 comparison.According to comparative result, when the Dust Capacity D0 measuring is equal to or greater than benchmark Dust Capacity D1, controller 140 determines that this Dust Capacity is large and performs step S703, and is less than in the situation of benchmark Dust Capacity D1 at the Dust Capacity D0 measuring, and controller 140 stops this process.
When being daytime, execution step S703 and supply fan 130 are controlled in having large Dust Capacity environment.Particularly, controller 140 rotates with multistage RPM speed (R1 to R4) according to the Dust Capacity D0 control supply fan 130 measuring.For example, when the Dust Capacity D0 measuring is greater than benchmark Dust Capacity D1, controller 140 is controlled supply fan 130 and is rotated with R1RPM.Similarly, when the Dust Capacity D0 measuring declines with relative uniform rate for benchmark Dust Capacity D1, controller 140 can be controlled the RPM rotation of supply fan 130 to reduce gradually, such as from R2, and R3 and R4.Here, opening relationships R1>R2>R3>R4.
When at night, perform step in the environment that Dust Capacity D0 that S704 and supply fan 130 measure is therein less than benchmark Dust Capacity D1 and controlled.In this situation, it is R4 rotation with minimum RPM speed in the multistage RPM speed (R1 to R4) arranging with respect to Dust Capacity that controller 140 can be controlled supply fan 130.
As mentioned above, according to embodiments of the invention, by suitably control the RPM of supply fan 130 according to illumination value, can for example adopt betwixt reduce noise the night of sleep pattern according to surrounding environment, realize the technique effect of the environment that remains good comfortable.And, according to another embodiment of the present invention, control method above can be applicable to have the equipment of various structures, and particularly, because HEPA filter and odor removal filter are arranged in the rear one-level of Dehumidifying element, can prevent HEPA filter and odor removal filter hydraulic performance decline and the lost of life.
Meanwhile, controller 140 can be carried out and comprise the various functions of function above.Particularly, controller 140 can be carried out the functions such as, overload control dry such as the control of air-flow power, defrosting, heat exchanger, the control of compressor start reducing noise.Below, detailed description is carried out to the operation of the controller 140 of corresponding function above.
First, will describe air-flow power controls.
Although dehumidification type air purifier does not drive therein Dehumidifying element 120 to filter out under the purification pattern of pollutant and moves by regulating the rotary speed of supply fan 130, but when input moves the dehumidifying run signal of Dehumidifying element 120, the rotary speed that controller 140 can determine whether move Dehumidifying element 120 or reset supply fan 130.That is, in the situation that dehumidification type air purifier moves under purification pattern, if the humidity of extraneous air higher than reference humidity value, or according to user input, the dehumidifying run signal of operation Dehumidifying element 120 can be imported into controller 140.
As mentioned above, the range of operation of the rotary speed of the supply fan 130 of dehumidification type air purifier is greater than the range of operation of the rotary speed of conventional dehydrating unit.Thus, when dehumidification type air purifier moves under purification pattern, the rotary speed of supply fan 130 can be set at outside the scope of rotary speed of dehydrating unit.In this situation, whether the rotary speed of supply fan 130 is adjusted to the speed previously set or no according to dehumidifying operation, to regulate the rotary speed of supply fan 130 may be a problem in purification pattern.
If the rotary speed of supply fan 130 is adjusted to the speed of previously setting in purification pattern, the rotary speed of supply fan 130 enough reduces the effect on moisture extraction of Dehumidifying element 120 soon and widely, if the rotary speed of supply fan 130 is set according to dehumidifying run signal, the rotary speed of supply fan 130 is changed, especially in functional purification pattern, cause potentially realizing the effect realizing by functional purification pattern expection.
In order to prevent this situation, purification pattern is divided into general purification pattern and functional purification pattern, and in general purification pattern situation, controller 140 can be set the operation of Dehumidifying element 120 and the rotary speed of supply fan 130 according to dehumidifying run signal, and when purification pattern is functional purification pattern, controller 140 can maintain the operation of functional purification pattern.
The general purification pattern pattern that can be the air-flow power wherein set based on user carry out air cleaning etc. to the air of introducing, and under this pattern, can not expect any other function or effect user under the air-flow power situation of setting.And the input of dehumidifying run signal means that the current needs of dehumidifying operation are performed, thereby can preferentially carry out dehumidification function.Thus, when input dehumidifying operation when dehumidification type air purifier is just moving, can carry out dehumidification function by Dehumidifying element 120, and the rotary speed of supply fan 130 can be reset to the dehumidifying speed of service according to dehumidifying run signal.
Meanwhile, functional purification pattern is to carry out the pattern of preset function (yellow dirt pattern, cloth drying pattern, sleep pattern etc.), and the rotary speed of supply fan 130 and corresponding air-flow power are vital for carrying out each function.Thus, under functional purification pattern, the rotary speed of the supply fan 130 of setting under functional purification pattern can be maintained former state and no matter dehumidifying run signal.
And, with respect to the operation of Dehumidifying element 120, according to supply fan 130 rotary speeies of dehumidifying operation and the supply fan rotary speed of setting in functional purification pattern, be different.Thus, while moving under Dehumidifying element 20 is the state of rotary speed of the supply fan 130 set under functional purification pattern, the effect on moisture extraction of Dehumidifying element 120 may reduce greatly.For the user who expects effect on moisture extraction, this can reduce the reliability of dehumidification type air purifier, so it can be configured so that not provide dehumidification function in functional purification pattern.
Here, after dehumidification type air purifier enters dehumidification mode, by dehumidifying, move, the humidity of extraneous air can be reduced to below reference humidity value.Under this situation, controller 130 can stop dehumidifying and move and turn back to purification pattern, and in this case, can reset according to the amount of pollutant in the extraneous air being measured by dust sensor S2 the rotary speed of supply fan 130.
In addition, controller 140 can receive the exterior lighting value from illumination sensor S3, and when received illumination value is during lower than preset value, controller 140 can move dehumidification type air purifier and enter sleep pattern, thereby stops the operation of Dehumidifying element 120.Here, controller 140 can receive the exterior lighting value being measured by illumination sensor S3 and identify the brightness outside dehumidification type air purifier.
When exterior lighting value is during lower than preset value, controller 140 determines that they are nights and move dehumidification type air purifier and enter sleep pattern.Sleep pattern is the pattern that wherein dehumidification type air purifier moves by minimizing the noise that produced by dehumidification type air purifier.Here, the most noises that produced by dehumidification type air purifier can by the noise of the rotation from supply fan 130 and when the compressor 122 of the dehumidified unit 120 of cold-producing medium produce when using motor compression audiogenic.
Thus, when dehumidification type air purifier is during in sleep pattern, controller 140 can stop the operation of Dehumidifying element 120, the particularly operation of compressor 122, thereby and the rotary speed that can set supply fan 130 supply fan 130 is moved under the speed of the noiseless speed lower than default.
But, here, when user directly inputs dehumidifying during run signal, although the exterior lighting value of illumination sensor S3 lower than preset value, dehumidification type air purifier can not moved to sleep pattern yet.That is,, in this situation, controller 140 can move Dehumidifying element 120 to carry out dehumidification function according to the user view that removes steam from air.
Particularly, dehumidification type air purifier therein user is directly inputted under the manual mode of dehumidifying run signal operation so that dehumidification type air purifier is carried out dehumidifying operation, and can be therein when user inputs target humidity indoor humidity level measured and when the indoor humidity level measuring during higher than target humidity dehumidifying move under the automatic mode of automatically execution and move.Thus, when dehumidification type air purifier moves under automatic mode, it can change under sleep pattern and move, and in the situation that dehumidification type air purifier moves under manual mode, dehumidification type air purifier can be carried out dehumidification function and not change to sleep pattern.
Defrost operation will be described below.
When dehumidification type air purifier is carried out dehumidifying operation in low temperature environment, being condensate in airborne steam on evaporimeter 121 can frosting on the surface of evaporimeter 121.That is, the surface of evaporimeter 121 can be by frosting and the wet-out property of evaporimeter 121 may reduce.
In related art, in order to remove being formed on frost on evaporimeter 121, the operation of supply fan 130 stop and compressor 122 in the warm refrigerant that produces directly branch to evaporimeter 121.But, for warm refrigerant is directly branched to evaporimeter 121, need other parts, and produced abnormal sound when evaporimeter 121 being defrosted with warm refrigerant, thereby likely cause user (or consumer) to think it is fault etc. by mistake.
Thus, in the present embodiment, controller 130 can determine whether dehumidification type air purifier to change to defrosting mode to remove the frost (or to evaporimeter 121 defrostings) being formed on evaporimeter 121, and when dehumidification type air purifier changes to defrosting mode, the rotary speed that controller 140 can cut off the power supply of compressor 122 and increase supply fan 130, to defrosting actuating speed, removes frost thus.
First controller 140 can receive from the temperature signal of temperature sensor of measuring the surface temperature of evaporimeter 121.When the temperature signal receiving is lower than defrosting during fiducial temperature, controller 140 can change to defrosting mode by dehumidification type air purifier.Here, reach fiducial time under temperature signal maintains defrosting fiducial temperature during or when longer, dehumidification type air purifier can change to defrosting mode, or dehumidification type air purifier can repeatedly change to defrosting mode to carry out Defrost operation by predetermined period.In addition, in general, whether dehumidification type air purifier being changed to defrosting mode can determine based on temperature signal, and when the temperature signal of not input temp signal or input is outside preset range, dehumidification type air purifier can change to defrosting mode by predetermined period.Here, when input temp signal is not maybe when the temperature signal of input is preset range outside, can determine that the temperature sensor of generation temperature signal exists error.
For example, when for example, for example, for (5 seconds) during measuring measured evaporimeter 121 surface temperatures of temperature sensor of the surface temperature of evaporimeter 121 and maintaining temperature under defrosting fiducial temperature (-1 ℃) to reach fiducial time or when longer, dehumidification type air purifier can change to defrosting mode.That is, when evaporimeter 121 maintains that temperature lower than defrosting fiducial temperature reaches certain duration or when more of a specified duration, the steam of the extraneous air of liquefaction frosting and produce frost on the surface of evaporimeter 121 in evaporimeter 121.
When dehumidification type air purifier enters defrosting mode, controller 140 can cut off the power supply of compressor 122 to stop the phase transformation of cold-producing medium.In the situation that without the phase transformation of cold-producing medium, the condensation of steam on evaporimeter 121 just stops, and prevents from thus making extra frosting at evaporimeter 121.
Next, the rotary speed of supply fan 130 can be increased to than the dehumidifying speed of service actuating speed that defrosts faster for the operation that dehumidifies.When the rotary speed of supply fan 130 increases, a large amount of extraneous airs can be introduced into evaporimeter 121.Here, extraneous air can have the temperature higher than the surface temperature of evaporimeter 121, transfers heat to evaporimeter 121, and frost can be exposed to the extraneous air of being supplied by supply fan 130 continually, thereby evaporation forms steam immediately.Correspondingly, the temperature of evaporimeter 121 is enhanced, with the surface defrosting to evaporimeter 121 (that is,, when the temperature of evaporimeter 121 improves, the lip-deep frost that is formed on evaporimeter 121 can disappear due to the temperature of this raising).
Thus, can carry out defrost function and without other parts, and because carry out defrost function under the cut state of power supply of compressor 122, so capable of reducing energy consumption.And in this case, owing to carrying out defrosting by increasing the rotary speed of supply fan 130, only producing the noise that the operation due to supply fan 130 brings does not have other noise.
Next, when the simultaneous temperature signal moving under defrosting mode when dehumidification type air purifier becomes higher than defrosting fiducial temperature, controller 140 can and be reduced to the dehumidifying speed of service by the rotary speed of supply fan 130 to compressor 122 power supplies.That is,, after being defrosted in the surface of evaporimeter 121 under defrosting mode, dehumidification type air purifier may need again under the dehumidification mode that removes humidity from extraneous air, to move.Thus, when by temperature sensor measurement to the surface temperature of evaporimeter 121 higher than defrosting during fiducial temperature, dehumidification type air purifier can change to dehumidification mode from defrosting mode.; controller 140 can be monitored by serviceability temperature sensor the temperature of evaporimeter 121; and when the temperature of evaporimeter 121 is during higher than defrosting fiducial temperature; controller 140 can determine that the frost being formed on evaporimeter 121 is removed completely, and dehumidification type air purifier turns back to dehumidification mode again.
In order to make dehumidification type air purifier turn back to dehumidification mode, controller 140 can and be reduced to dehumidifying running temperature by the rotary speed of supply fan 130 to compressor 122 power supplies.When power supply is provided to compressor 122, can recover the continuous phase transistion of cold-producing medium, and correspondingly, the air that is introduced into evaporimeter 121 is cooled and steam can be by condensation again.And in order effectively the airborne steam that is contained in introducing evaporimeter 121 to be removed, the rotary speed of supply fan 130 can be reduced to the dehumidifying speed of service.
The dry operation of heat exchanger will be described below.
When the dehumidifying end of run of dehumidification type air purifier, moisture is retained in the heat exchanger 121 and 123 of Dehumidifying element 120.If the moisture being retained in heat exchanger 121 and 123 is not removed immediately, harmful microorganism, mould etc. can be propagated therein, and the inside of heat exchanger 121 and 122 may be polluted, and can produce therein stink beastly by harmful microorganism, mould etc. propagation.
Thus, controller 140 can determine whether dehumidification type air purifier to change to heat exchanger drying mode to remove remaining moisture, especially the moisture in the heat exchanger 121 and 123 of Dehumidifying element 120.When dehumidification type air purifier changes to heat exchanger drying mode, controller 140 can be controlled the operation of supply fan 130 extraneous air is supplied to heat exchanger 121 and 123.
First, can be according to determining that for making control signal that the operation of compressor 122 stops whether be imported into controller 140 whether dehumidification type air purifier is in heat exchanger drying mode.
Heat exchanger drying mode is that wherein heat exchanger 121 and 123 is dried the operational mode that prevents harmful microorganism in Dehumidifying element 120, mould etc. propagation when stopping the dehumidification function of dehumidification type air purifier user immediately.That is, heat exchanger 121 and 123 is dried when stopping dehumidification function, has prevented thus the stink beastly producing because of harmful microorganism, mould etc. when dehumidification type air purifier is driven afterwards again.Thus, because heat exchanger drying mode should be carried out after dehumidification function stops, need to identifying dehumidification function and whether stop.In order to carry out dehumidification function, cold-producing medium should be first compressed.Thus, can be by determining whether the whether compressed dehumidification function of identifying of cold-producing medium stops.
Thus, when control signal that input stops for the operation that makes compressor 122, controller 140 determines that dehumidification function stops, and dehumidification type air purifier is changed to heat exchanger drying mode.
But here, in dehumidification type air purifier situation, contingent is that dehumidifying operation is terminated and dehumidification type air purifier moves subsequently under purification pattern.That is, heat exchanger 121 and 123 can be dried according to the rotation of the supply fan 130 using in purification pattern.Thus, controller 140 can be considered for whether control signal that the operation of supply fan 130 stops being transfused to and for whether the control signal that the operation of compressor 122 stops is transfused to.
In addition, during the running time of user input or programming in advance, controller 140 can receive from the control signal for preventing that the operation that makes compressor 122 of the holding circuit etc. of compressor 122 overloads from stopping.
When dehumidification type air purifier changes to heat exchanger drying mode, controller 140 can according to heat exchanger temperature value and heat exchanger humidity value be set the speed of service of supply fan 130 and during running time.
Particularly, when heat exchanger temperature value and heat exchanger humidity value are during higher than reference temperature value and reference humidity value, controller 140 can be set supply fan 130 and under first speed of service, move during the first running time.Here, when the rotary speed of supply fan 130 be divided into from the height near slow, while neutralizing low three speed class, first speed of service can correspond to midrange speed grade, and when being divided into from growing to shorter height during the running time of supply fan 130, while neutralizing low three levels, can correspond to senior first duration of operation.That is,, when heat exchanger temperature value and heat exchanger humidity value are while being high, supply fan 130 can move fast and reach long-time section with dry heat exchanger 121 and 123 fully.
Next, when heat exchanger temperature value is lower than reference temperature value but heat exchanger humidity value during higher than reference humidity value, supply fan 130 can be provided in operation under second speed of service and reach for second duration of operation.Here, second speed of service can correspond to low speed grade, and can correspond to middle rank second duration of operation.
Finally, when heat exchanger temperature value is lower than reference temperature value and heat exchanger humidity value during lower than reference humidity value, supply fan 130 can be provided in operation under the 3rd speed of service and reach for the 3rd duration of operation.Here, the 3rd speed of service can correspond to low speed grade, similar second speed of service, and can correspond to rudimentary the 3rd duration of operation.
Here, also can consider heat exchanger temperature wherein higher than reference temperature value but heat exchanger humidity value lower than the situation of reference humidity.In this situation, can omit the operation of dry heat exchanger 121 and 123.
Controller 140 according to another embodiment of the present invention can only be set the speed of service and the duration of operation of supply fan 130 by heat exchanger humidity value.That is, can be by heat exchanger humidity value and default minimum humidity value and default maximal humidity value being compared to set the speed of service and the duration of operation of supply fan 130.
Particularly, when heat exchanger humidity value is greater than default minimum humidity value, the speed of service of supply fan 130 can be configured to midrange speed grade, and can be set to the duration of operation of supply fan 130 senior to a large amount of steam that are present in heat exchanger 121 and 123 are removed reliably.
And when heat exchanger humidity value is less than default maximal humidity value but is greater than default minimum humidity value, the speed of service of supply fan 130 can be set to low speed grade, and can be set to middle rank the duration of operation of supply fan 130.That is, the speed of service of supply fan 130 and the duration of operation slight reduction or reduce effectively to remove humidity.
Finally, when heat exchanger humidity value is greater than while being less than default minimum humidity value, the speed of service of supply fan 130 can be configured to low velocity grade and can be set to the duration of operation of supply fan 130 rudimentary, to control the operation of supply fan 130 according to the situation with a small amount of humidity.
To describe overload below controls.
When by carry out when operation dehumidifying with Dehumidifying element 120, particularly, while carrying out dehumidifying operation in the hot environment such as summer, in heat exchanger 121 and 123, may not carry out smoothly heat exchange, likely cause compressor 122 overheated and damage, maybe may make the operation of compressor 122 stop.In order to prevent this point, controller 140 can determine whether dehumidification type air purifier to change over overload pattern to solve the overload that is applied to Dehumidifying element 120.When dehumidification type air purifier changes to overload pattern, controller 140 can be increased to overload actuating speed by the rotary speed of supply fan 130.
Particularly, controller 140 can by use by the temperature sensor measurement of measuring external temperature to the external temperature of dehumidification type air purifier or the size of current that is introduced into the motor of compressor 122 determine whether dehumidification type air purifier to change over overload pattern.That is, when the external temperature value of input is greater than overload a reference value, controller 140 can be determined Dehumidifying element 120 overloads, and when size of current is greater than reference current value, controller 140 can be determined Dehumidifying element 120 overloads.When controller 140 is determined Dehumidifying element overload, controller 140 can change over overload pattern by the operational mode of dehumidification type air purifier.In addition,, even when the temperature of heat exchanger is during higher than default temperature value, controller 140 can be determined overload and dehumidification type air purifier is become to overload pattern.
When the operational mode of dehumidification type air purifier corresponds to overload pattern, dehumidification type air purifier can preferably be carried out for solving the operation of the Dehumidifying element 120 of overload.That is, controller 140 can be brought up to overload actuating speed by the rotary speed of supply fan 130.Overload actuating speed is the rotary speed that surpasses the rotary speed of general dehumidifying operation.When supply fan 130 moves with overload actuating speed, Dehumidifying element 120 can be cooled.Work as Dehumidifying element, particularly, when compressor 122 is cooled, can solve the overload of Dehumidifying element 120.
In addition, controller 140 can be according to being moved by the recommendation humidity action command of use interface unit (not shown) input by user under the humidity pattern of recommending, and interface unit may be attached to the outside of dehumidification type air purifier.That is,, when user inputs the humidity action command of recommendation, the humidity run signal of recommendation can be input to controller 140.
When the humidity run signal of recommending is transfused to, controller 140 can receive the outer moisture value being measured by humidity sensor S1.When outer moisture value surpasses reference humidity value for example 60% time, thereby can moving Dehumidifying element 120, controller 140 to control airborne steam, outer moisture value is reduced to below 60%.When outer moisture value is in the humidity range of recommending, for example 40% to 60%, can stop dehumidifying operation.Here, the humidity range of reference humidity value and recommendation can be limited to aforesaid value and scope, and can be changed and set.
To describe compressor start reducing noise below controls.
When input dehumidifying run signal, first, controller 140 can be brought up to default rotary speed by the rotary speed of supply fan 130.Next, Dehumidifying element 120 is can be only driven during higher than default rotary speed in rotary speed.
In order to make dehumidification type air purifier carry out dehumidification function, require supply fan 130 and Dehumidifying element 120 all to move.Here, when Dehumidifying element 120 has just brought into operation, may produce noise and vibration due to the operation of Dehumidifying element 120, and, the sudden change noise and vibration that user may be caused by the operation by Dehumidifying element 120 is given a start and is determined that the operation of dehumidification type air purifier exists fault here.
Meanwhile, in general, the noise that the noise ratio being produced by the rotation of supply fan 130 is produced by the operation of Dehumidifying element 120 can not hear, and user may enough be familiar with and by the noise of the rotation generation by supply fan 130, do not given a start.
Thus, controller 140 can drive supply fan 130 before the operation of Dehumidifying element 120.By the noise by driving supply fan 130 to produce, user can identify dehumidification type air purifier and bring into operation, and next,, although Dehumidifying element 120 moves to produce noise and vibration, user can be identified as it the normal operation of dehumidification type air purifier.And the noise producing due to the operation of Dehumidifying element 120 can be submerged in the noise that the driving by supply fan 130 produces, thereby user can identify the relatively low-grade noise that the operation due to Dehumidifying element 120 produces.
Particularly, in order to realize rightly the effect that drives for the first time supply fan 130, Dehumidifying element 120 can rerun after supply fan 130 is with pre-set velocity or more speed operation.That is,, because the size of the noise for being produced by the rotation of supply fan 130 should enough cover the noise being produced by Dehumidifying element 120, the rotary speed of supply fan 130 can be configured to produce the noise with supply fan 130 desired amplitudes in advance.
After receiving dehumidifying run signal, controller 1400 can move supply fan 130, and after supply fan 130 receives the rotary speed of supply fan 130, controller 140 can be repeatedly by received rotary speed and default rotary speed comparison.Next, when the rotary speed of the supply fan 130 measuring is during higher than default rotary speed, controller 140 can be passed to control signal Dehumidifying element 120 to start the operation of Dehumidifying element 120.Or supply fan 130 reaches the time period that default rotary speed spends and is set in advance, when this Preset Time section past tense, controller 140 can move Dehumidifying element 120.
Here, controller 140 can be controlled the operation of the compressor 122 of Dehumidifying element 120 particularly.As discussed above, compressor 122 can be used for by using motor compressed refrigerant, thereby the noise and vibration being produced by Dehumidifying element 120 may be derived from the motor of compressor 122.
Thus, work as rotary speed, particularly, the rotary speed of supply fan 130 is during higher than default rotary speed, and controller 140 can drive compression machine 122.Here, when supply fan 130 moves under default rotary speed, can produce the noise with the level that is equal to or greater than the noise producing when the compressor 122 wait moving starts.
Controller 140 can receive dehumidifying run signal.When controller 140 receives dehumidifying run signal, thereby controller 140 can be controlled dehumidification type air purifier Dehumidifying element 120 execution dehumidification functions.Dehumidifying run signal can be by user by being arranged on the interface unit (not shown) of dehumidification type air purifier outside and inputting or being transfused to when externally the humidity value of air is higher than reference humidity value.
After drive compression machine 122, controller 140 can be reset to the dehumidifying speed of service by the rotary speed of supply fan 130.When drive compression machine 122, the situation starting than compressor 122, can reduce noise and vibration.Thus, when compressor 122 starts when driven, the speed that the rotary speed of supply fan 130 can be reduced to be suitable for dehumidifying operation dehumidify the speed of service and rotate.
Fig. 8 is for controlling the flow chart of process of method of the air-flow power of dehumidification type air purifier according to one embodiment of the invention.
With reference to figure 8, according to one embodiment of the invention, for controlling the method for the air-flow power of dehumidification type air purifier, comprise air cleaning step (S810), dehumidifying run signal input step (S820), purification pattern type actuation step (S830), dehumidifying step (S840) and function purifying step (S850).
Next, will describe according to one embodiment of the invention for controlling the method for the air-flow power of dehumidification type air purifier.
In air cleaning step (S810), the rotary speed of supply fan can be to set according to default purification pattern, and can filter out the pollutant being contained in the extraneous air of introducing due to the rotation of supply fan.Purification pattern can comprise general purification pattern and functional purification pattern.General purification pattern can be that the rotary speed of wherein supply fan sets and be contained according to the air-flow power of customer requirements the pattern that the airborne pollutant introduced by supply fan removes by being suitable for filter.Functional purification pattern can be that each rotary speed that wherein supply fan is set according to corresponding function in advance according to it is moved to carry out thus the pattern of corresponding function.This functional purification pattern can be such as comprising yellow dirt pattern, cloth drying pattern, nighttime sleep pattern etc.In yellow dirt pattern situation, the various noxious pollutant concentration of introducing the yellow dust concentration of room area and be contained in Huang Chenzhong between yellow dirt seasonal period may be high, thereby yellow dirt pattern can be that the deleterious material being wherein introduced in dehumidification type air purifier can be by the pattern of fast processing.Sleep pattern can be the pattern that wherein thereby its noise of dehumidification type air purifier operation is minimized.In sleep pattern, the rotary speed of supply fan is set to minimum.
In dehumidifying run signal input step (S820), can receive the dehumidifying run signal of operation Dehumidifying element so that the steam being contained in extraneous air is removed.When dehumidification type air purifier moves under purification pattern, can receive dehumidifying run signal, and, dehumidifying run signal also can comprise the information about the rotary speed of supply fan here.In this situation, whether the rotary speed of supply fan 130 being set to the speed previously set in purification pattern or no supply fan rotary speed according to dehumidifying run signal, to set the rotary speed of supply fan 130 may be a problem.; if the rotary speed of supply fan 130 is adjusted to the speed of previously setting in purification pattern; the rotary speed of supply fan 130 enough reduces the effect on moisture extraction of Dehumidifying element 120 soon and widely; and on the contrary; if the rotary speed of supply fan 130 is set according to dehumidifying run signal; the rotary speed of supply fan 130 is changed, and especially, in functional purification pattern, likely causes realizing the effect of expecting realization by functional purification pattern.Here, dehumidifying run signal can directly receive from user there, even and if when externally the humidity of air is higher than reference humidity value, also can receive dehumidifying run signal.
In purification pattern type determining step (S830), can determine that purification pattern is general purification pattern or functional purification pattern.As discussed above, purification pattern can be divided into general purification pattern and functional purification pattern, thereby can distinguish dehumidification type air purifier, corresponds at present which pattern.Here, when purification pattern is general purification pattern, can carries out dehumidifying step (S840), and when purification pattern is functional purification pattern, can carry out function purifying step (S850).Aforesaid problem can solve by distinguishing the pending step of purification pattern.
In dehumidifying step (S840), when purification pattern is general purification pattern, the rotary speed of supply fan can reset according to dehumidifying run signal, and Dehumidifying element can move to carry out dehumidifying operation.General purification pattern is the air-flow power wherein set based on the user pattern of the air of introducing being carried out to air cleaning etc., and under this pattern, can not expect any other function or effect user under the air-flow power situation of setting.And the input of dehumidifying run signal means that the current needs of dehumidifying operation are performed, thereby can consider preferentially to carry out dehumidification function.Thus, when input dehumidifying operation when dehumidification type air purifier is just moving, can carry out dehumidification function by Dehumidifying element 120, and the rotary speed of supply fan 130 can be reset to the dehumidifying speed of service according to dehumidifying run signal.In dehumidifying step (S840), dehumidification type air purifier can be carried out dehumidifying operation and remove steam from air.Here, according to the humidity value of extraneous air, the rotary speed of supply fan can be reset to the dehumidifying speed of service of previous setting.
In function purifying step (S850), when purification pattern is functional purification pattern, can maintains the rotary speed of supply fan and not carry out dehumidifying operation.Functional purification pattern can be the preset function of carrying out such as yellow dirt pattern, cloth drying pattern, sleep pattern etc., and in order to carry out these functions, importantly the rotary speed of supply fan is maintained to the rotary speed of setting in functional purification pattern.Thus, under functional purification pattern, the rotary speed of the supply fan of setting under functional purification pattern can be maintained former state and no matter dehumidifying run signal.And, with respect to dehumidifying operation, when being maintained, the rotary speed of the supply fan of setting carries out dehumidifying operation in functional purification pattern, and effect on moisture extraction may reduce greatly and this may damage the user's of dehumidification type air purifier reliability.Thus, when dehumidification type air purifier moves under functional purification pattern, no matter dehumidification type air purifier may not carried out dehumidifying operation and dehumidifying run signal.Here, dehumidification type air purifier can show on display that it can not carry out the fact of dehumidifying operation, and this display can be arranged in the shell of dehumidification type air purifier.
In addition, although not shown, but the method for controlling the air-flow power of dehumidification type air purifier also can comprise air cleaning and return to step, wherein, when in the step (S840) that dehumidifies, the humidity of extraneous air is reduced to lower than reference humidity value afterwards, dehumidification type air purifier is back to purification pattern.That is, user may want to maintain humidity and the air cleaning degree of certain level, and in this case, in dehumidifying step (S840) afterwards, dehumidification type air purifier may need to turn back to purification pattern.Here, in order to set the rotary speed of supply fan, the amount of the pollutant in extraneous air can be measured by dust sensor, and the rotary speed of supply fan can the amount based on pollutant be set.Particularly, the purification actuating speed that corresponds to the supply fan of the Dust Capacity of being measured by dust sensor can be set in advance, can purify the rotary speed that actuating speed resets supply fan based on this.
And in the method for air-flow power of controlling dehumidification type air purifier, exterior lighting value is measured, and when the illumination value measuring is during lower than reference illumination value, dehumidification type air purifier changes to sleep pattern, thereby stops the operation of Dehumidifying element.This exterior lighting value can be the value of being measured by the illumination sensor that is arranged on dehumidification type air purifier outside.When the exterior lighting value being measured by illumination sensor is during lower than preset value, can determine that it is night and moves dehumidification type air purifier and enter sleep pattern.
Sleep pattern is that wherein thereby the operation of dehumidification type air purifier makes user's sleep not by the pattern of the noise jamming being produced by dehumidification type air purifier, and under this pattern, dehumidification type air purifier can move by minimizing from the noise of its generation.Particularly, the most noises that produced by dehumidification type air purifier can be caused by the noise of the rotation from supply fan and the sound being produced when using motor compression by the compressor of Dehumidifying element when cold-producing medium.Thus, when dehumidification type air purifier is in sleep pattern lower time, can stop the operation of compressor of Dehumidifying element and supply fan with the rotary speed operation lower than default sleep pattern rotary speed.
But, here, when user directly inputs dehumidifying during run signal, although the exterior lighting value of illumination sensor lower than preset value, dehumidification type air purifier can not moved to sleep pattern yet.That is,, in this situation, Dehumidifying element can move to carry out dehumidification function according to the user view that removes moisture from air.
Particularly, dehumidification type air purifier therein user is directly inputted under the manual mode of dehumidifying run signal operation so that dehumidification type air purifier is carried out dehumidifying operation, and can be therein when user inputs target humidity, indoor humidity level is measured, and when the indoor humidity level measuring is during higher than target humidity, under the automatic mode that dehumidifying operation is automatically carried out, move.Thus, when dehumidification type air purifier moves under automatic mode, it can change under sleep pattern and move, and in the situation of moving under manual mode at dehumidification type air purifier, dehumidification type air purifier can be carried out dehumidification function and not change to sleep pattern.
And in the method for air-flow power of controlling dehumidification type air purifier, when input cloth drying signal, Dehumidifying element is moved and the rotary speed of supply fan is increased to cloth drying speed simultaneously.Cloth drying speed can be inputted by interface unit, and this interface unit can be arranged on the shell of dehumidification type air purifier.When receiving cloth drying signal, the operation that can control dehumidification type air purifier carrys out rapid draing clothing.
Particularly, can utilize the method for moving Dehumidifying element simultaneously and the rotary speed of supply fan being increased to cloth drying speed.In general, when when dehydrating unit is carried out dehumidification function, air velocity is too fast, dehumidification function may not normally be carried out.But, about being dried of clothing, may more effectively be that supply large quantity of air is to remove the humidity being contained in clothing.Thus, the rotary speed of supply fan can be set to than for carrying out the higher cloth drying rotary speed of maximum rotative speed of dehumidification function.That is, although according to the wet-out property of the execution of the dehumidification function of Dehumidifying element, may reduce, by having additional supply of to the air capacity of clothing drying clothes rapidly.
For reference, in description above, be expressed as and sequentially carry out corresponding step, but these steps can executed in parallel or the execution sequence of corresponding step can change.
Fig. 9 is according to the flow chart of the process of the Defrost method of the dehumidification type air purifier of one embodiment of the invention.
With reference to figure 9, Defrost method can comprise that dehumidifying operation (S910), defrosting mode change operation (S920), Defrost operation (S930) and dehumidification mode and sharply return to (S940) according to an embodiment of the invention.
Below, with reference to Fig. 9, describe according to the Defrost method of the dehumidification type air purifier of one embodiment of the invention.
In dehumidifying operation (S910), cold-producing medium passes through compressor compresses, by condenser, liquefy and by evaporating with evaporimeter with the cooling air of being introduced thus, thus, under the removed dehumidification mode of airborne humidity that dehumidification type air purifier can be introduced therein, move.Dehumidifying operation (S910) can be by using compressor, condenser and evaporimeter to remove the general dehumanization method of airborne humidity.
At defrosting mode, change in operation (S920), can determine whether that dehumidification type air purifier is changed to defrosting mode is formed on the frost on evaporimeter to remove.When carrying out dehumidifying in low temperature environment, airborne humidity is chilled on the surface of evaporimeter, thereby forms frost on evaporator surface.When the surperficial frosting of evaporimeter, humidity can not successfully be removed from evaporimeter, therefore needs to remove frost.Here, dehumidification type air purifier can change to defrosting mode to remove frost with the dehumidification mode of removing in dehumidifying the same mode in service from humidity wherein.
At defrosting mode, change in operation (S920), when the surface temperature of evaporimeter is during lower than defrosting fiducial temperature, dehumidification type air purifier can change to defrosting mode.In order effectively to remove humidity, preferably, only in evaporimeter frosting, carry out Defrost operation, thereby may importantly determine that dehumidification type air purifier changes to the time point of defrosting mode.In order to determine that dehumidification type air purifier changes to the time point of defrosting mode, can utilize the surface temperature of evaporimeter, and the surface temperature of evaporimeter can be measured by temperature sensor.Particularly, the surface temperature of evaporimeter can be measured by serviceability temperature sensor, and lower than defrosting, during fiducial temperature, can think that evaporimeter has been defrosted when the surface temperature measuring.Defrosting fiducial temperature can be the temperature that the steam of liquefaction starts frosting in evaporimeter.In addition, during temperature signal maintains defrosting fiducial temperature to reach fiducial time or when longer, dehumidification type air purifier can change to defrosting mode, or dehumidification type air purifier can repeatedly change to defrosting mode to carry out Defrost operation by predetermined period.In addition, in general, whether changing to defrosting mode can determine based on temperature signal, and when the temperature signal of not input temp signal or input is outside preset range, dehumidification type air purifier can change to defrosting mode with predetermined period.When input temp signal is not maybe when the temperature signal of input is preset range outside, can determine that the temperature sensor of generation temperature signal exists error.
In Defrost operation (S930), when defrosting formula air purifier changes to defrosting mode, can be cut to the power supply of compressor and the actuating speed of supply fan is brought up to defrosting actuating speed.When determining that frost is formed on the surface of evaporimeter, dehumidification type air purifier can change to defrosting mode with to evaporator defrost.In defrosting mode, by being cut to the power supply of evaporimeter, can stop at the cooling air being introduced in evaporimeter.This is in order to prevent from by the cooling of evaporimeter forming extraly frost.And the actuating speed of supply fan can be brought up to defrosting actuating speed to allow a large amount of extraneous airs to be provided to evaporimeter.Extraneous air can have the temperature higher than the temperature of evaporimeter, thereby it can transfer heat to evaporimeter.Due to the heat of being transmitted by extraneous air, the surface temperature of evaporimeter can improve, and correspondingly, can remove the frost being formed on evaporator surface.
At defrosting mode, return to (S940) in service, when evaporimeter is defrosted in defrosting mode, dehumidification type air purifier can be back to dehumidification mode.That is,, after the frost on being formed at evaporimeter is removed, dehumidification type air purifier need to turn back to dehumidification mode to remove humidity the air from introducing.Particularly, at defrosting mode, return in operation S940, when the surface temperature of evaporimeter, bring up to than defrosting fiducial temperature when higher, can be reduced to the dehumidifying speed of service to the actuating speed of compressor power supply and supply fan.When the surface temperature of evaporimeter is during higher than defrosting fiducial temperature, frost can not be present on the surface of evaporimeter, thereby can think that the lip-deep frost at evaporimeter is removed.Thus, when the surface temperature of evaporimeter is during higher than defrosting fiducial temperature, dehumidification type air purifier can turn back to dehumidification mode.In order to turn back to dehumidification mode, air that can be cooling introduced to compressor power supply and evaporimeter is to remove steam from it.And for effective dehumidifying, the actuating speed of supply fan can be reduced to the dehumidifying speed of service from defrosting actuating speed.
Figure 10 is according to the flow chart of the process of the drying means of the heat exchanger of the dehumidification type air purifier of one embodiment of the invention.Figure 11 is the flow chart of process of drying means of the heat exchanger of dehumidification type air purifier according to another embodiment of the present invention.
The method (or heat exchanger drying means) of dry heat exchanger is described with reference to Figure 10 and 11.
With reference to Figure 10, heat exchanger drying means can comprise that operation (S1030) is set in dehumidifying (S1010) out of service, sensor measurement operation (S1020), operation and supply fan drives operation (S1040) according to an embodiment of the invention.
In dehumidifying (S1010) out of service, the dehumidifying of dehumidification type air purifier operation can stop.Owing to carrying out the dry of heat exchanger after should having moved in the dehumidifying of dehumidification type air purifier, can first stop the dehumidifying operation of dehumidification type air purifier.Can stop dehumidifying operation according to user input, or can stop dehumidifying operation in default dehumidifying running time past tense.Or, when the humidity level of extraneous air is less than reference humidity value, can stop dehumidifying operation.
In sensor measurement operation (S1020), when dehumidifying operation stops, can be located at internal temperature and the humidity that temperature and moisture sensors in dehumidification type air purifier is measured dehumidification type air purifier by use.Here, temperature and moisture sensors can be measured the temperature and humidity of heat exchanger.Can control the operation for the supply fan of dry heat exchanger according to measured temperature and humidity value.

Figure 12 is for controlling the flow chart of process of method of the overload of dehumidification type air purifier according to one embodiment of the invention.
With reference to Figure 12, according to one embodiment of the invention, for controlling the method for overload of dehumidification type air purifier, comprise and filter that operation (S1210), dehumidifying operation (S1220), overload pattern change operation (S1230), overlond running (S1240), dehumidification mode returns to operation (S1250) and recommendation humidity operation (S1260).
Next, will describe according to one embodiment of the invention for controlling the method for the overload of dehumidification type air purifier.
In filtering operation (S1210), the air of introducing about the air-flow owing to being formed by supply fan, can be contained in this airborne pollutant by leaching with filter element.Filter element can be divided into the first filter element and the second filter element, the first filter element is for filter out pollutant when air is introduced into dehumidification type air purifier, and the second filter element filters out pollutant when outside for the Bas Discharged dehumidification type air purifier being introduced into.Corresponding filter element can comprise a plurality of filters.The first filter element can comprise prefilter, functional filter etc., and the second filter element can comprise HEPA filter, odor removal filter etc.
In dehumidifying operation (S1220), cold-producing medium is compressed by compressor, by condenser, liquefy and by evaporating with evaporimeter with the cooling air of being introduced thus, thus, under the removed dehumidification mode of airborne humidity that dehumidification type air purifier can be introduced therein, move.When dehumidification type air purifier, carry out dehumidifying operation when removing steam from air, dehumidification type air purifier can move under the dehumidification mode that uses compressor, condenser, evaporimeter etc.But the heat exchange in evaporimeter can significantly be affected by the external temperature of dehumidification type air purifier, and when external temperature is equal to or higher than overload temperature, may not successfully carry out the heat exchange in evaporimeter.In this situation, compressor may be overheated, to allow high-level air-flow to flow into wherein, and in order to protect compressor, can stop the operation of compressor.Because the heat exchange in evaporimeter is not smooth, wherein overheat of compressor with operate in high-level air-flow therein mobile state can be described as overload.
In overload pattern, change in operation (S1230), can determine whether to change to overload pattern to solve the overload that is applied to compressor.When compressor is out of service due to overload, dehumidification type air purifier can stop dehumidifying operation, therefore in order to prevent like this, can carry out control.First, in order to determine whether compressor transships, can measure the external temperature of dehumidification type air purifier or air-flow size that measurement is supplied to compressor, and the value measuring can with a reference value comparison.That is,, when the external temperature of the dehumidification type air purifier measuring or the air-flow size that is supplied to compressor are greater than overload reference temperature value and reference gas flow valuve, can determine overload of compressor.When determining overload of compressor, can control dehumidification type air purifier and under overload pattern, move to solve the overload of compressor.
In overlond running (S1240), when dehumidification type air purifier changes to overload pattern, the rotary speed of supply fan can be brought up to overload actuating speed.Supply fan is used for allowing extraneous air to introduce dehumidification type air purifier also can be by rotating to form air-flow.Supply fan can be carried out the operation of air-cleaning function and dehumidification function, thereby it can have the rotational velocity range larger than the speed of general dehumidifier.Thus, under overload pattern, supply fan can transship actuating speed operation faster than the rotary speed of general dehumidifier, and the extraneous air of being supplied by supply fan can absorb from the heat of compressor with cooling compressor thus.As discussed above, when compressor is cooled, does not exist the operation that stops compressor protecting the needs of compressor, thereby carry out serially dehumidifying operation.
At dehumidification mode, return in operation (S1250), when being applied to the mistake of compressor, be loaded in while being solved in overlond running (S1240), dehumidification type air purifier can turn back to dehumidifying operation.Due in overlond running (S1240), the speed of supply fan is brought up to overload actuating speed with cooling compressor, and than general dehumidifying operation, the wet-out property of dehumidification type air purifier can reduce.Thus, when external temperature value drops to overload, maybe when being supplied to the air-flow of compressor, be reduced to reference gas flow valuve when following during fiducial temperature, dehumidification type air purifier can turn back to dehumidification mode from overload pattern.
In recommending humidity operation (S1260), when humidity run signal is recommended in input, outer moisture is measured.When the humidity measuring surpasses reference humidity value for example 60% time, can carry out dehumidifying operation (S1220).Dehumidification type air purifier can move under recommendation humidity pattern, and in this case, user can be by carrying out input with interface unit, and this interface unit is attachable to the outside of dehumidification type air purifier.Under the humidity pattern of recommending, can receive the outer moisture value by humidity sensor measurement, and when outer moisture value surpasses 60%, can carry out dehumidifying operation (S1220).Next, when outer moisture value for example 40% to 60% time, can stop the operation of dehumidifying operation (S1220) in the humidity range of recommending.
For reference, in description above, corresponding operation is described as order and carries out, but when reality is carried out these operations, these operations can parallel execution or these operations order can change.
Figure 13 is according to the flow chart of the control procedure of the compressor noise of the reduction dehumidification type air purifier of one embodiment of the invention.
With reference to Figure 13, according to the dehumanization method of the dehumidification type air purifier of one embodiment of the invention, can comprise that dehumidifying run signal input operation (S1310), supply fan operation (S1320), rotary speed detection operation (S1330) and Dehumidifying element drive operation (S1340).
Below, with reference to Figure 13, describe according to the dehumanization method of the dehumidification type air purifier of one embodiment of the invention.
In dehumidifying run signal input operation (S1310), the Dehumidifying element of dehumidification type air purifier can receive for controlling the dehumidifying run signal of Dehumidifying element and carry out dehumidifying operation to remove steam from air.Dehumidifying run signal can be that the Dehumidifying element of operation dehumidification type air purifier is with by the signal of removing from the steam that is introduced into dehumidification type air purifier.Can receive the dehumidifying run signal from user by being arranged in the interface unit (figure position) of dehumidification type air purifier outside.Dehumidification type air purifier can be carried out individually from air and removes the dehumidification function of steam and remove the air-cleaning function of pollutants in air or can carry out this two functions simultaneously.Can only when carrying out dehumidification function or while carrying out at the same time dehumidification function and air-cleaning function, input dehumidifying run signal.
In supply fan operation (S1320), when input dehumidifying run signal, can move supply fan to allow extraneous air to be introduced in dehumidification type air purifier.When input dehumidification type run signal, can move supply fan, and, noise may produce due to the operation of supply fan here.In order to carry out dehumidifying operation, supply fan should move with together with Dehumidifying element in being located at dehumidification type air purifier, and, before operation Dehumidifying element, only can move supply fan here.
In rotary speed detecting unit (S1330), whether the rotary speed that can determine supply fan equals or faster than default rotary speed.After supply fan operation, can determine the rotary speed of supply fan.As mentioned above, first rotating inlet fan is produce first the noise that the operation by supply fan produces and then move Dehumidifying element.Thus, the rotary speed of supply fan can improve gradually until when it reaches default rotary speed.In general, the noisiness of generation, along with the rotary speed of supply fan increases and improves, therefore can detect the rotary speed of supply fan and determine whether the noise being produced by supply fan is increased to the target noise level that reaches.Here, the large I of target noise is equal to or greater than the noise producing when operation Dehumidifying element.
At Dehumidifying element, drive in operation (S1340), when the rotary speed of supply fan equals or during faster than default rotary speed, can drive the Dehumidifying element of dehumidification type air purifier.That is, when the rotary speed of supply fan equals or during faster than default rotary speed, the noisiness being produced by supply fan can be equal to or greater than target noise.Thus, at this time point place, although the Dehumidifying element of dehumidification type air purifier is driven, user may not can the noise and vibration of driven Dehumidifying element give a start and can't wrong think the fault of dehumidification type air purifier.Here, drive dehumidifying can specifically mean compressor, an element of Dehumidifying element is driven.Compressor compresses cold-producing medium, and because compressor, by carrying out compressed refrigerant with motor, can produce a large amount of noise and vibrations when compressor operating.Thus, when supply fan equaling or rotary speed faster than default rotary speed under while moving, particularly, the compressor of Dehumidifying element can start driven.
Although not shown, after driving Dehumidifying element, can carry out extraly the dehumidifying speed of service that the rotary speed of supply fan is reset to the dehumidifying speed of service, reset operation.At Dehumidifying element, particularly compressor driven after, can reduce the noise and vibration being produced by compressor.Thus, when compressor starts is driven, the rotary speed of supply fan can reduce and supply fan can be to be suitable for the speed rotation of dehumidifying operation, with the rotation of the dehumidifying speed of service.
Although illustrate and described the present invention in conjunction with each embodiment, those skilled in the art is apparent that and can carries out various modifications and variations and not depart from the spirit and scope of the present invention that appended claims limits.
