And, control device 18 store external detection device 16 when obtaining distance Lmax towards elevation angle gamma s and anglec of rotation ω s and distance Lmax.At this, anglec of rotation ω s represent external detection device 16 towards the angle rotated in the horizontal direction from the initial position preset.Above-mentioned distance Lmax, elevation angle gamma s and anglec of rotation ω s comprise the information relevant with the width in the room that air purifier 1 is set up.That is, based on distance Lmax and elevation angle gamma s, the width=Lmax × cos (γ s) obtaining room is used as the width in room.
In addition, distance Lmax, elevation angle gamma s and anglec of rotation ω s comprise with in the relevant information of indoor distances air purifier 1 wall farthest (being expressed as wall farthest below).The research making people of the present utility model shows, as shown in Figure 4, this farthest wall be the wall of the best forming circulating current when discharging air and blowing in room entirety.Describe in more detail, if discharge air towards target location P, then can form circulating current in room entirety, what target location P referred to ceiling is positioned at the part of marginal corner near the position of front side certain distance d compared and become wall and ceiling farthest.In addition, also confirm the size variation of distance d according to room, such as, in the room of the broadness more than 17 tatamis, being the value also less than the half of the distance to wall farthest, if give an example, is then about d=2m.
Like this, according to indoor scan process, can determine to be adapted at the target location P that room entirety forms the wind direction of circulating current.In addition, above-mentioned indoor scan process forms the concrete example that mechanism determined by wall, and this wall determines that mechanism determines the wall of the best forming circulating current.
In next process, arrive the mode of the target location P of ceiling based on elevation angle gamma s and anglec of rotation ω s setting wind direction to make discharging air, and utilize movable shutters plate 12 and oscillating head mechanism 14 to realize this wind direction.In addition, set air quantity in the mode making the discharge air arriving target location P form circulating current based on distance Lmax, and control to realize this air quantity by the rotating speed of fan assembly 6.In addition, in circulating current controls, such as with the width of indoor, have unmanned and animal etc. accordingly, utilize two movable shutters plates 12 to adjust the aperture area of outlet 5, and the wind speed suitably controlling to discharge air is to make to bring sense of discomfort because blowout high wind.
By carrying out circulating current control by this way, as shown in Figure 4, air is discharged blowing to the target location P of ceiling and return air purifier 1 along landing ground after wall farthest.Thus, control according to circulating current, the circulating current of room entirety circulation stably can be formed in the various rooms that width is different, the polluter at each position being present in room can be pooled to efficiently the position of air purifier 1, the time needed for purification of room air can be shortened.In addition, in circulating current controls, what make external detection device 16 owing to utilizing oscillating head mechanism 14 carries out the detection action of wall farthest, therefore, it is possible to stably detect wall farthest for various room shape towards changing in left-right direction.
In addition, in circulating current controls, also following structure can be formed as: swing along the vertical direction at the reference elevation angle θ a that can form circulating current, the wind direction of discharging air with the chien shih of maximum elevation θ b, and repeat this wobbling action, wherein, maximum elevation θ b is set to the elevation angle larger than elevation angle theta a.At this, reference elevation angle θ a is the elevation angle of this wind direction when setting wind direction in the mode of the target location P making arrival ceiling.In addition, maximum elevation θ b is set to the arbitrary angle larger than elevation angle theta a, can set in 90 °, also can be formed as the structure changed based on the indoor information utilizing external detection device 16 to detect.According to this control, circulating current can be formed in room entirety, and the air that can make to be trapped near the ceiling directly over being positioned at when air purifier 1 is observed also forms air-flow, can purify the Efficient air of indoor.
At this, the effect obtained by performing circulating current control in the air purifier 1 of ground-set type is described.Usually, because the dust etc. of indoor is present in ground more, therefore air purifier 1 is preferably disposed on ground, to remove dust efficiently.On the other hand, by detecting the horizontal range of clarifier 1 to the wall in front indoor, the width in room etc. can be held and implement to make the optimized control of air-flow, but, be set with the barriers such as furniture due on the ground more, be therefore difficult to stably detect the horizontal range from the position of air purifier 1.Therefore, in the present embodiment, external detection device 16 is utilized to detect corner farthest between wall and ceiling.And, be formed as following structure: the width in the room estimated with the elevation angle gamma s based on the distance Lmax to this corner and corner accordingly, at least one air blast parameter of discharging in the wind direction of air, air quantity and wind speed is controlled, discharges air from outlet 5 oblique upper forward.
According to this structure, in the diversified room that the configuration etc. of furniture is different, the indoor information suitable with the width in room can be detected at the spatial stability of oblique upper, this detection action can be suppressed by obstruction such as furniture.In addition, owing to can discharge being formed the air of circulating current obliquely from outlet 5, therefore, it is possible to suppress the air-flow of discharging air to blow to furniture etc. and the situation of disorder, can stably form the circulating current corresponding with the width in room.Thus, the advantage of the air purifier 1 of ground-set type of can applying in a flexible way, can give full play to its performance.
In addition, because the width, shape etc. in room are varied, therefore utilize oscillating head mechanism 14 make external detection device 16 towards variable range when changing in the horizontal direction, detected object scope in horizontal direction, be preferably set to cover and play scope till the wall of the left and right sides from the wall (mostly usually being wall farthest) in the front being positioned at air purifier 1.In addition, detected object scope in horizontal direction can be formed as the structure changed based on the testing result of indoor information, as long as the scope in the corner farthest between wall and ceiling can be detected, be non-essentially set to the maximum variable scope utilizing oscillating head mechanism 14 to realize.In addition, make external detection device 16 towards variable range when changing along the vertical direction, detected object scope on above-below direction, be preferably set at least comprise the scope till playing directly over vertical from horizontal direction (if with towards elevation angle gamma represent, be then the scope of 0≤γ≤90 °).Thereby, it is possible to stably detect the corner farthest between wall and ceiling in the room with various shape.
In addition, in the present embodiment, as described later, the variable quantity based on the distance detected by external detection device 16 identifies wall and ceiling and barrier, and controls Overblow state.When this control is actuated, the scope of the variable range broadness than the wind direction formed needed for circulating current should mostly be in the scope of indoor detection barrier.Therefore, the detected object scope of external detection device 16 is preferably set at least as comprising the broad range of variable range of wind direction as the part of its scope.Thereby, it is possible to detect barrier in the broad range of indoor and tackle.
Next, be described with reference to the concrete example of Fig. 5 to the control utilizing control device 18 to carry out.Fig. 5 is the flow chart of the example that the control performed by air purifier in embodiment 1 of the present utility model is shown.In addition, premised on structure external detection device 16 being located at movable shutters plate 12, the program shown in this figure is described.In the program shown in Fig. 5, first, if detect in step sl, air purifier 1 is connected this situation with power supply, then in step s 2 by driving drive division 13 and oscillating head mechanism 14 and make movable shutters plate 12 and outlet 5 move to initial position.That is, the elevation angle theta of movable shutters plate 12 and outlet 5 anglec of rotation ω are in the horizontal direction set as initial value (θ=θ 0, ω=ω 0).
Next, in step s3, the variable i used in the circular treatment that will be described below, j, k are initialized as zero.At this, i, j, k be respectively counting when switch in circular treatment elevation angle theta, anglec of rotation ω, fan assembly 6 rotating speed r time be in the count value in which stage.Describe in detail, in set variable range, from θ 0 to θ, n1 periodically changes the elevation angle theta of movable shutters plate 12.N1 represents number of stages when elevation angle theta is changed in variable range.And, under the state of i=0, select θ 0 as elevation angle theta.In addition, under the state of i=n1, be set to elevation angle theta=θ n1.
Identical therewith, in set variable range, from ω 0 to ω, n2 periodically changes the anglec of rotation ω of outlet 5, and n2 represents number of stages when anglec of rotation ω is changed in variable range.The rotating speed r of fan assembly 6 periodically changes in set variable range from r0 to rn3, and n3 represents number of stages when rotating speed r is changed in variable range.Thus, in step s3, when being energized to control device 18, the state that elevation angle theta, anglec of rotation ω are configured to θ 0, ω 0 is respectively become.In addition, above-mentioned i, j, k, n1, n2, n3 are natural number.
Next, in step s 4 which, determining whether to operate the power switch of air purifier 1, when operating, by step 5 drive fan device 6, starting blowing action.Next, in step s 6, perform pollutant and map process, map in process at this pollutant, detect the pollutional condition at each position of the interior space, and store testing result for each position.The pollutant being provided with the pollutional condition of each several part in locker room at the memory circuit of control device 18 stores mapping.
Pollutant stores to map such as to be mapped by three-dimensional data and forms, for the concentration C of each storage pollutant of each mesh point determined as independent variable using elevation angle theta, anglec of rotation ω, rotating speed r ijk.In addition, concentration C ijksubscript i, j, k corresponding with aforesaid count value, respectively in the range of 0 ~ n1,0 ~ n2,0 ~ n3.In addition, in the utility model, the concentration of non-essential use pollutant, as index, also can be formed as that other physical quantitys that there is correlation with pollution level are stored in pollutant and store the structure mapped.
Map in process at pollutant, first, under the condition of elevation angle theta=θ 0, anglec of rotation ω=ω 0 and rotating speed r=r0, from outlet 5 to indoor discharge air, and by time T1 that purification of air action executing is set by method described later.Afterwards, repeat to make count value i increase by 1 and by the action of purification of air action executing time T1, until reach number of stages n1 at every turn.Now, control device 18 utilizes internal inspection device 15 to detect pollutant in the air being sucked into suction inlet 4 after indoor circulation, and the concentration C will obtained based on testing result ijkbe stored in pollutant and store mapping.As a result, in initial process, under the condition of anglec of rotation ω=ω 0 and rotating speed r=r0, obtain the concentration C at each position corresponding with elevation angle theta 0 ~ θ n1 000, C 100, C 200..., C n100.
Next, make count value j increase by 1, under the condition of anglec of rotation ω=ω 1 and rotating speed r=r0, make elevation angle theta at the scope change of θ 0 ~ θ n1 as described above, while for each detectable concentration C at each elevation angle ijk.Thus, the concentration C at each position corresponding with elevation angle theta 0 ~ θ n1 when obtaining anglec of rotation ω=ω 1 010, C 110, C 210..., C n1n20.Then, repeat process identical therewith at anglec of rotation ω 2 ~ ω n2, thus, when rotating speed r=r0, obtain combining corresponding concentration C with elevation angle theta and all of anglec of rotation ω ij0.Further, increase count value k and rotating speed r to be obtained at every speed r in the range of r1 ~ rn3 combine corresponding concentration C with elevation angle theta and all of anglec of rotation ω ijk.As shown in Figure 5, above-mentioned processing example is as recirculated processing execution as 3.
Thus, map in process at pollutant, the concentration C that pollutant stores all mesh points on mapping can be upgraded ijk.In addition, in the above example, according to the order of elevation angle theta, anglec of rotation ω, rotating speed r, value is changed, but this order can free setting.In addition, in the utility model, non-essential elevation angle theta, anglec of rotation ω and rotating speed r all to be changed.In addition, the time T1 continuing to carry out purification of air action a position such as sets based on the following time, and this time is: play the time required till this air returns to the position of internal inspection device 15 from being discharged air by purification of air action, namely can detect the time causing pollutant to reduce by performing purification of air action.
In addition, in each detection position of the concentration of detection of contamination, first, the concentration detecting pollutant when starting purification of air action is used as initial concentration c0.When initial concentration c 0 exceedes the decision content X preset, can be judged to be will towards the position air blast of polluting.Decision content X is such as based on the state setting that the pollutant without the need to carrying out purification of air action is few.In addition, also can be formed as following structure: when initial concentration c 0 is below decision content X, be judged to be that current detection position is not polluted, directly terminate purification of air action and transit to next to detect position.In addition, in the utility model, also can omit the detection of initial concentration c0, be formed as structure initial concentration c0 being set as constant constant.
In next process, concentration c 1 at the end of the concentration detecting pollutant purification of air action carried out after time T1 is used as.Then, using the concentration C of concentration c at the end of this 1 as current detection position ijkbe stored in pollutant and store mapping.In addition, in the present embodiment, exemplify following process: even if under the state that concentration c 1 exceedes decision content X at the end of such as, also when have passed through time T1 starting from purification of air action, transitting to next and detecting position.
In common detection position, if start purification of air action, then the concentration of the pollutant detected reduces, in most cases concentration c 1 at the end of initial concentration c0 >.But, when the generation source of pollutant is fixing, c0≤c1 sometimes.Therefore, also following structure can be formed as: map in process at pollutant, detect position at each, calculate the attenuation rate α of the pollutant caused by performing purification of air action, and it can be used as attenuation rate α ijkbe stored in pollutant and store each mesh point on mapping.The formula of following numerical expression 1 illustrate based on initial concentration c0 and at the end of concentration c 1 calculate an example of the method for attenuation rate α.In addition, the Application way of attenuation rate α will illustrate in the step s 7.
Numerical expression 1: α=1-c1/c0
According to the formula of above-mentioned numerical expression 1, attenuation rate can be calculated at short notice, the error of action response can be suppressed, the computational accuracy of attenuation rate can be improved.In addition, attenuation rate can be calculated by method beyond above-mentioned formula, such as, also can calculate by the following method: with initial concentration c0 with at the end of the difference of concentration c 1 divided by time T1, the time variations calculating concentration is thus used as attenuation rate.In addition, also can be formed as utilizing the coefficient relevant to the width in room to revise the structure of attenuation rate.
In addition, in the utility model, also following structure can be formed as: before pollutant mapping process starts, perform aforesaid indoor scan process to detect the width in room, and change the variable range of elevation angle theta, anglec of rotation ω and rotating speed r based on this testing result, or change number of stages n1, n2, n3 of elevation angle theta, anglec of rotation ω and rotating speed r based on this testing result.According to this structure, variable range, number of stages n1, n2, n3 optimization of elevation angle theta, anglec of rotation ω and rotating speed r can be made accordingly with the width in room.That is, such as, in broad room, increase variable range and increase number of stages, the precision that pollutant maps process can be improved thus.In addition, in narrow and small room, reduce variable range and reduce number of stages, indoor scanning can be carried out thus efficiently.
After pollutant mapping process terminates, transit to step S7.After step S7, extract in the indoor scope scanned and pollute the most serious position as gdna contamination, make wind direction towards this gdna contamination, carry out the process preferentially pollutant at this position purified.While carry out fine setting to wind direction while by this processing execution time T2.At this, " fine setting " refers to following action: wind direction is fine changed near gdna contamination, while detect the pollution level of the air returned from gdna contamination, and carries out FEEDBACK CONTROL according to this testing result to wind direction.
Describe in detail, first, in the step s 7, extract pollutant and store C in each mesh point mapped ijk>=X and attenuation rate α ijkthe mesh point that≤Y sets up.At this, Y is the decision content for determining whether to obtain fully the effect of purification of air action preset.The mesh point extracted by step S7 is exceeded allowed band with pollutant and can be corresponding by the gdna contamination of purification of air action decreasing pollution thing.In addition, exemplified with using attenuation rate α in the step s 7 ijksituation, but in the utility model, also can be formed as not using attenuation rate and extracting only C ijkthe structure of the mesh point that>=X sets up.
Next, in step s 8, whether there is C in the mesh point that judgement extracts ijkthe mesh point of>=X.When this judgement is set up, transit to step S9, in extracted mesh point, select C ijkmaximum mesh point.This mesh point is corresponding with the most serious position of pollution in existing gdna contamination, therefore by the concentration C of the pollutant of this mesh point ijkstore as Cmax Cmax, and utilize drive division 13, oscillating head mechanism 14 and fan assembly 6 to realize the elevation angle theta corresponding with this mesh point i, anglec of rotation ω j, rotating speed r k.Thus, become the wind direction of discharge air towards the state polluting the most serious position, therefore, in step slo, towards pollution the most serious position air blast, by purification of air action executing time T2, return step S8 afterwards.
In addition, time T2 be the air of gdna contamination is purified needed for time, the magnitude relationship of itself and time T1 can set arbitrarily, but is preferably set to the time longer than time T1.In addition, at C ijkwhen there are many places in the gdna contamination of>=X, preferably for a gdna contamination by purification of air action executing after time T2, the effect whether obtaining purification at this position all transits to next gdna contamination.Then, for all gdna contaminations, purification of air action executing, after time T2, is being repeated pollutant and mapping process from first.Now, be stored in pollutant and store the concentration C mapped ijkall upgrade when each change wind direction, remain the state storing up-to-date pollution level.Thereby, it is possible to purify equably room entirety.
On the other hand, when gdna contamination is only 1 place, preferably continue the purification of air action carrying out this gdna contamination, until pollutant is purified fully, namely until C ijktill < X sets up.In addition, when continuing from fixed position to produce pollutant, can based on attenuation rate α ijkdetermine whether air purification effect.And, when confirming effect, preferably such as continue removing pollutant when not making wind direction significantly change, until the concentration of pollutant or the rate of decay become the threshold value preset.
According to above-mentioned control, there is C as long as store in mapping at pollutant ijkthe mesh point of>=X, just repeats the process of step S8 ~ S10, from the gdna contamination that the pollutant degree in the gdna contamination extracted by step S7 is large, perform purification of air action successively.And if all gdna contaminations are all cleaned, then the judgement of step S8 becomes is false, and therefore transits to step S11.In step s 11, at random change the rotating speed r of fan assembly 6 and by blowing action time of implementation T3, return step S6 afterwards.
At this, when there is not C ijkwhen the mesh point of>=X, namely at all position pollutant levels C ijkwhen being all less than decision content X, mean that indoor entirety is cleaned, stop purification of air action also harmless even if original.But, because indoor are not airtight space, therefore can produce natural ventilation, thus, although be that a small amount of dust on the whole continues to flow into.In addition, after carrying out primary air purification action, if through after a while, there is the situation of indoor generation pollutant new in a large number.Therefore, air purifier 1 needs the state of the pollutant in regular monitoring room.Therefore, air purifier 1 preferably returns step S6 after execution step S11, proceeds purification of air action thus, continues removing and flows into indoor new pollutant.
Now, the rotating speed r of fan assembly 6 such as can use the arbitrary rotating speed r of initial setting or the operating and setting based on user, but is preferably set to lower rotating speed.Its reason is, the amount being flowed into indoor pollutant by natural ventilation is more micro-, even if therefore reduce rotating speed r (i.e. air quantity), also can obtain the clean-up effect of pollutant fully.And, by the r that not excessively increases speed, the action sound of fan assembly 6 grade can be reduced while the cleanliness factor keeping air, or suppress people etc. because of by wind to and produce brush sense.Thus, can carry out purification of air action swimmingly, user but can not be made to recognize, and air purifier 1 is in work.
In addition, the rotating speed r of fan assembly 6 is non-essential is steady state value.That is, the amount being flowed into the pollutant of indoor by natural ventilation significantly can be changed because of the impact of season, weather, extraneous air etc.Thus, the structure that rotating speed r changes based on the testing result of the pollutant utilizing internal inspection device 15 to detect can be also formed as.Thereby, it is possible to suppress the increase of the pollutant caused due to various variable in Min., the comfortableness of user can be maintained.
On the other hand, in step s 11, the time T3 proceeding blowing action can be selected by user, also can use the value preset.In addition, time needed for pollutant of the diffusion time of indoor pollutional condition, produced pollution thing, removing can be also formed as considering and structure that the time of making T3 changes.Thereby, it is possible to more efficiently carry out purification of air action.In addition, it is desirable to press stop button until user or till pulling up attaching plug, continue the process carrying out step S6 ~ S11.In addition, in the present embodiment, also can be formed as the moment after being purified by all gdna contaminations, namely perform the moment of step S11, carry out aforesaid circulating current control.
In addition, in above-mentioned control, at use attenuation rate α ijkwhen, when carrying out purification of air action for each gdna contamination, also can add based on attenuation rate α ijkthe determination processing of carrying out.If enumerate concrete example, then also can be formed as following structure: at attenuation rate α ijkfor the gdna contamination of below decision content Y, be judged as the effect that fully cannot obtain purification of air action, and preferentially carry out the purification of other gdna contaminations.In addition, decision content Y can adopt the usage corresponding with its setting.First, to being set as that the situation of Y=0 carries out describing.In this case, at α ijk, there is the possibility in generation source that purification of air action does not play function completely or becomes dust, therefore, it is possible to be judged as that this gdna contamination is not suitable for the removing of pollutant in the gdna contamination that≤Y sets up.
In addition, also can in the concentration C of arbitrary gdna contamination when pollutant ijkfor being set as attenuation rate α when below decision content X ijk=X.Its reason is, such as, when being set as Y=0, as long as can make concentration C ijkdecay a little, although then spended time also proceeds purification of air action till becoming clean, the efficiency of purification easily reduces.In this case, if set attenuation rate α as described above ijk, then the efficiency of purification can be improved.
In addition, though do not illustrate in Figure 5, work as at all mesh point α ijk≤ 0 when all setting up, and can judge that air purifier 1 becomes the generation source of pollutant.Also can be formed as following structure: in this case, judge that its reason is that job failure occurs fan assembly 6, filter class reaches the life-span etc., carry out the report action of urging user's putting maintenance into practice.
In addition, in the present embodiment, when barrier being detected in the blowing action carried out when control based on above-mentioned circulating current, pollutant mapping process etc., also can perform and keep away people's control, control Overblow state in the mode making air-flow can not blow to this barrier.If enumerate concrete example, then keeping away in people's control, making the distance detected to detected object thing towards change of external detection device 16, when this distance significantly changes suddenly, the change based on this distance identifies indoor barrier.And, when wind direction is towards barrier, such as, performs and avoid action, as the action that turns off the blast, weaken air-flow etc.According to this control, the situation that air-flow blows to people, dust blows afloat by animal and air-flow after bringing sense of discomfort or blowing to barrier can be suppressed, comfortableness during purification of air can be improved.
In addition, in the present embodiment, also can be formed as the structure performed concurrently by blowing action when indoor scan process and purification of air, blowing action during purification of air comprises circulating current control, pollutant mapping process etc.According to this structure, even if do not distribute the special time to indoor scan process, also can with common blowing action scanning room's internal information concurrently, even if when the change in location of such as barrier, also can revise blowing action rapidly accordingly with this change.
In addition, in the present embodiment, also can be formed as following structure: when the power supply such as power line and socket of air purifier 1 is connected, automatically change external detection device 16 towards, while perform indoor scan process.According to this structure, such as, can be arranged at the indoor moment at air purifier 1 and obtain indoor information in advance.And, when user operates power switch, also can start blowing action immediately even if do not scan indoor, suitable air-flow can be formed rapidly based on acquired indoor information.Thus, the convenience of air purifier 1 can be improved.
In addition, in the present embodiment, also following structure can be formed as: during the power switch opening air purifier 1 from user is to startup fan assembly 6, perform indoor scan process.According to this structure, indoor information can be obtained before being about to carry out purification of air action, even if when the position of such as barrier changes, also on the basis corresponding with this change, blowing action can be carried out exactly.
As described in detail above, according to the present embodiment, at the diversified air-flow arranged in environment in suitably control room, can stably can purify the air of room entirety.Describe in detail, in general family, the configuration of room layout, furniture, the configuration of air purifier 1 etc. are different from each other, therefore, if wall is excessively far away apart from air purifier 1, then there is the situation that wind cannot arrive wall, if otherwise wall is excessively near, then there is the situation of carrying out excessive running.As a result, the noise that there is air purifier 1 becomes large or wind brings the problem of sense of discomfort, creeping chill etc. to people.On the other hand, in the present embodiment, the indoor information (distance especially to wall) detected based on utilizing external detection device 16 suitably controls at least one the air blast parameter in wind direction, air quantity and wind speed, therefore, it is possible to solve the problem, circulating current can be formed at room monolithic stability.
In addition, external detection device 16 possess at least more than one use the fluctuation of non-transmissive of ultrasonic wave, optical, electrical magnetic wave etc. and so on detect distance between barrier contactless range sensor, be preferably ultrasonic sensor.The test example of distance is as undertaken by triangulation etc. based on the data of imageing sensor, but the process of image information expends time in this case, and the response of purification of air action easily reduces.Obtain indoor information at short notice thereby, it is possible to do not lose time, the response of air purifier 1 can be improved.
In addition, in the present embodiment, external detection device 16 is equipped on movable shutters plate 12.Thereby, it is possible to make range sensor etc. towards consistent exactly with wind direction, the accuracy of detection of the distance on the direction of wind direction can be improved.In addition, driving external detection device 16 can be made common with the drive division 13 of movable shutters plate 12, the movable part of device can be reduced and improve reliability, and cost reduction can be realized.
