In addition, in the present embodiment, although be illustrated with the example with electrostatic atomization portion 180, therefore the structural element that its Bu Shi warm braw mechanism is required also can be the structure without electrostatic atomization portion 180.
The structure in <2> electrostatic atomization portion
Below, the structure in the electrostatic atomization portion in the electric heater of present embodiment is described with reference to Fig. 2.
As shown in Figure 2, electrostatic atomization portion 180 is made up of the electrostatically atomizing unit 181 etc. be arranged in the electrostatic atomization air channel 151 with atomization blow-off outlet 182.Electrostatic atomization air channel 151 is arranged to branch out from the air channel 150 between pressure fan 160 and heater 170 as described above.
Although not shown, electrostatically atomizing unit 181 is at least made up of condensed water generating unit, atomizing electrode, opposite electrode etc.Condensed water generating unit makes the condensate moisture in the air sent here by pressure fan 160 and generates water.Atomizing electrode and opposite electrode relatively configure, and apply voltage to the water generated by condensed water generating unit.
Specifically, condensed water generating unit is formed for main composition parts with the Peltier's element with cooling base and heat-radiating substrate.The cooling base of Peltier's element is provided with pointed atomizing electrode.And be configured to, to atomizing electrode conveying by the condensed water of the cooling base of Peltier's element.
Further, in the position opposed with pointed atomizing electrode, the opposite electrode of general dome shape (comprising dome-shaped) is configured with in the mode of surrounding atomizing electrode.Further, by applying the DC voltage of such as about 3500V between atomizing electrode and opposite electrode, the condensed water being transported to atomizing electrode is made to produce Rayleigh division.Thus, the charged particle water of nanoscale size is produced.
That is, by the charged particle water of the air rubber capsule after electrostatically atomizing unit 181 containing nanoscale size, charged particle water is discharged into outside via atomization blow-off outlet 182 from blow-off outlet 140.Now, be discharged into charged particle water in extraneous air when its concentration is suitable, the user of indoor played to the moistening effect of skin.The moistening effect of charged particle water is different from the skin makeup effect that the humidity based on simple humidification adjusts.Specifically, the moist skin makeup effect produced by there is nano level charged particle water with concentration to a certain degree in atmosphere can have been given play to.
Further, the charged particle glassware for drinking water of nanoscale size has for the decomposition removal effect of foul smell composition and the bactericidal effects etc. for various mushroom such as such as ammonia, acetaldehyde, acetic acid, methane, carbon monoxide, nitric oxide, formaldehyde.Thereby, it is possible to for being suspended in indoor and being attached to wall and ground foul smell composition and mushroom, play the effects such as deodorization, degerming and sterilization.
The action of <3> electric heater, effect
Below, action and the effect of the electric heater in present embodiment are described.
When starting the running of electric heater 100, first, the power switch 121 of operating portion 120 is set to " connection " by user.Further, by each switch of operating portion 120, the operation mode of hobby is selected.As operation mode, such as, there are " warm braw ", " humidification ", " electrostatic atomization " these three basic operation modes.In addition, also there is the operation mode etc. of " the humidification warm braw " simultaneously carrying out " warm braw " and " humidification ".Further, the operation mode of " electrostatic atomization " is configured to except independent operation mode, can also realize the operation mode that can carry out simultaneously operating with the operation mode of other " warm braw ", " humidification ", " humidification warm braw ".
Further, when carrying out the running of warm braw pattern, user further selectively operates one of them of the continuous switch 122 of warm braw or warm braw room temperature linked switch 123.Now, when have selected warm braw continuous switch 122, electric heater 100 is the capacity of " by force " or " weak " with heater 170, irrelevantly blows out warm braw with room temperature.On the other hand, when have selected warm braw room temperature linked switch 123, operate as follows: in linkage the capacity of heater 170 is suitably switched to such as 1200W or 600W etc. with room temperature, thus make room temperature keep predetermined temperature.
And then when carrying out the running of warm braw pattern, air door 190 is configured in the position D closing humidification air channel 153.Further, be only provided to warm braw air channel 152 by the warm braw after heater 170 heats, and directly blow out from blow-off outlet 140 via warm braw air channel 152.Now, the warm braw of blowout has at high temperature carried out dry state.Therefore, warm braw pattern be suitable for room within the short time for for the purpose of drying of warming up.
Then, when carrying out the running of humidifying mode, the humidification switch 124 of user to operating portion 120 operates.When the running of humidifying mode, the capacity of heater 170 is set to low capacity (about 600W).Now, air door 190 is configured in the main position C sending warm braw to humidification air channel 153.Thus, the warm braw of low temperature is sent to both warm braw air channel 152 and humidification air channel 153.Its result, by the warm braw of the drying regime behind warm braw air channel 152 with by humidification air channel 153 and by the nearby mixing of the humidifying air after humidifying part 200 humidification at blow-off outlet 140, and blows out from blow-off outlet 140.
That is, when humidifying mode, a part for warm braw is directly blown out from warm braw air channel 152.Thereby, it is possible to obtain following effect: suck efficiently and blow out flow velocity faster warm braw at the humidifying air nearby carrying out mixing of blow-off outlet 140.
Then, when the running of humidification warm braw pattern performing warm braw mode operation and humidifying mode running simultaneously, user operates one of them switch of the continuous switch 122 of warm braw or warm braw room temperature linked switch 123 and humidification switch 124 as described above.
Specifically, when the running of humidification warm braw pattern, the position of air door 190 and ventilation state identical with the situation of humidification operation mode.But heater 170 operates with the heap(ed) capacity of 1200W.Therefore, humidification warm braw pattern is most suitable for blowing out warm braw after appropriate humidification, long-time cosily to the situation that room heats.
Then, when carrying out the running of electrostatic atomization pattern, the electrostatic atomization switch 125 of user to operating portion 120 operates.Thus, be energized to electrostatically atomizing unit 181.Further, electrostatically atomizing unit 181, from the moisture that the air sent by pressure fan 160 comprises, produces the charged particle of nanoscale size.The air comprising charged particle externally blows out from blow-off outlet 140 via atomization blow-off outlet 182.
In addition, the running of electrostatic atomization pattern can be implemented in the mode of individual operation, but, also can operate with warm braw, humidification operates, each operation mode such as humidification warm braw running operates simultaneously.Therefore, in any one operation mode, can both for being suspended in indoor and being attached to wall and ground foul smell composition and mushroom, play the effects such as deodorization, degerming and sterilization.
That is, the electric heater of present embodiment can operate under above-mentioned each operation mode.
Further, in case of a shut down, user carries out "off" operation to power switch 121.Thus, the running of electric heater 100 stops.
The electric heater of present embodiment carries out action as described above.
Below, the control method of Fig. 4 to the electric heater of present embodiment is used to be described.In addition, electric heater utilizes the signal detected by body detecting part to control each operation mode etc.
Fig. 4 is the block diagram of the structure of each key element illustrated in present embodiment.
As shown in Figure 4, the control system that electric heater controls at least is made up of body detecting part 301, human detection control part 501, main body control portion 401 etc.
Here, the body detecting part 301 of present embodiment is made up of human body sensor 311, and this human body sensor 311 is such as made up of thermoelectric transducer etc.When human body sensor 311 detects human body in its visual field, output signal in response to the change of infrared ray amount.That is, when human body is movable in the visual field of human body sensor 311, the change of infrared ray amount is produced.Consequently, with the activity of human body correspondingly, produce signal by body detecting part 301.
Human detection control part 501, according to the signal exported from body detecting part 301, judges the existence of human body, does not exist.Further, human detection control part 501, according to result of determination, indicates the stopping of running and usual the continuing of running to main body control portion 401.
In addition, human detection control part 501 has measurement unit 511 non-detection time, nobody determines Time dependent portion 512, unmanned detection unit 513 etc.Action and the effect of these parts will describe later.
Now, main body control portion 401 is transfused to the above-mentioned each operation mode such as warm braw, humidification, atomization set by operating portion 120.
Further, main body control portion 401, according to the running instruction of human detection control part 501 and the instruction from operating portion 120, carries out shutting down and remaining in operation of the function be set in warm braw mechanism 701, humidification mechanism 801, electrostatic atomization mechanism 901.
Now, when the unmanned detection unit 513 of human detection control part 501 determine there is not user, the repertoires such as main body control portion 401 makes usually, warm braw, humidification, atomization shut down.But in the present embodiment, the running of warm braw and atomizing functions stops, and continues the running of humidification mechanism.
Thus, following unfavorable condition can be prevented: when making the repertoire such as warm braw, humidification, atomization all shut down, till detecting that people returns to comfortable humidity when playing and restarted running from body detecting part 301, the more time be spent next time.In addition, operating by being set to only humidification function, reducing the electric energy needed for running of other functions such as warm braw and atomizing functions.In addition, also can not have in the electric heater of humidification function, stop repertoire.Therefore, it is possible to unnecessary power consumption when reducing nobody when not destroying comfortableness.Its result, can realize the electric heater having comfortableness and energy-saving effect concurrently.
Below, the action of Fig. 5 to the human detection control part of present embodiment is used to be described.
Fig. 5 is the flow chart of the action of the human detection control part illustrated in present embodiment.In addition, human detection control part 501, every certain sampling time, performs the handling process shown in Fig. 5.
As shown in Figure 5, first, non-measurement unit 511 confirmation detection time of human detection control part 501 has the signal (step S1) of body detecting part 301 output of having no way of.When the signal do not exported from body detecting part 301 ("No" of step S1), to carrying out timing (step S2) non-detection time.Further, to until body detecting part 301 detects that sigtnal interval, i.e. the signal non-detection status (state of no signal) of the human detection signal of human body lasting time (non-detection time) measures.Now, when human body being detected by body detecting part 301 ("Yes" of step S1), remove the timing (step S3) of (reset) non-detection time.Thus, the detection of new non-detection time is started.
Then, nobody of human detection control part 501 determine Time dependent portion 512 according to described later nobody determine the determining method of time to determine that nobody determines the time (step S4).
Then, the unmanned detection unit 513 of human detection control part 501 is to determining non-detection time and nobody that the time compares (step S5).Now, continue for ("Yes" of step S5) when nobody determines the time of time more than in non-detection time, be judged to be to there is not human body (step S6).And then, indicate running to stop or economize on electricity running 1 (step S7) to main body control portion 401.On the other hand, be less than ("No" of step S5) nobody determines the time in non-detection time, be judged to be to there is human body (step S8).And then, usual running (step S7) is indicated to main body control portion 401.
Further, during electric heater 100 carries out work, above-mentioned action carrys out human body repeatedly.
Below, with reference to the flow chart of figure 5, and the concrete action of Fig. 6 to the electric heater of present embodiment is used to be described.
Fig. 6 is the key diagram of the operating condition of the electric heater illustrated in present embodiment.
As shown in Figure 6, first, when human detection control part 501 determine there is not human body, the electric heater of present embodiment makes operating condition from usually transferring to running 1 of economizing on electricity.That is, when human detection control part 501 determine there is not human body time, stop the warm braw as warm air function to operate, the humid control proceeded as humidification function operates.
Now, humidification function reduces target humidity and carries out low humidity control running.Thus, when nobody, can suppress and continue to carry out the power consumption that common humidification running correspondingly causes and increase.But, control in running at low humidity, if excessively reduce target humidity, then when running restarts, till returning to the comfort humidity as the target humidity of running usually, the more time will be spent.Therefore, in the present embodiment, such as, the target humidity usually operated is set as about 55%, target humidity time nobody is set as the low humidity of about 40%.
Then, under the state of carrying out running control with running 1 of economizing on electricity, when people enters into indoor again, determined by human detection control part 501 and there is people.Thus, electric heater works with usual drive manner again.
In addition, when not having the electric heater of humidification mechanism, when determine there is not people time, stop the warm braw as warm air function to operate.Further, this state is maintained, until human body detected by body detecting part 301 next time.
<4> nobody determine the determining method of time
Below, Fig. 7 A to Fig. 8 is used to determine that the determining method of time is described to nobody shown in Fig. 5.
Fig. 7 A and Fig. 7 B is the figure of the signal detection state that the body detecting part in present embodiment is shown according to time series.Fig. 8 be illustrate in present embodiment nobody determine the state transition diagram of the action in Time dependent portion.
That is, as described in Figure 5, nobody determines that Time dependent portion 512 determines to determine the time as nobody of fiducial value, and this fiducial value is used for the non-detection time according to detecting in step s 2, judges the situation that there is not human body.
Use Fig. 7 A and Fig. 7 B particularly, compare signal detection state when to employ electric heater under different using states, illustrate that nobody determines the determining method of time simultaneously.
In addition, nobody determines that the decision of time judges every determination time T0 from running starts.Now, in the present embodiment, the maximum of the non-detection time obtained by clocking internal during the T0 time is set as Tmax, time of nobody being determined shorter nobody determines that the time is set as Tshort (such as 3 minutes), and longer nobody is determined that the time is set as Tlong (such as 7 minutes).
First, under the using state of the electric heater shown in Fig. 7 A, when there being people, within the T0 time, be timed as shorter nobody determines that the non-detection time of time more than Tshort does not once have yet.Now, in the T0 time after this, timing obtains shorter nobody when determining the non-detection time of time more than Tshort, if the using state of same electric heater, then the possibility that there is not user is higher.Therefore, the time of preferably nobody being determined is set as that shorter nobody determines time Tshort to control.
On the other hand, under the using state of the electric heater shown in Fig. 7 B, even if there is people, within the T0 time, also exist and be timed as shorter nobody determines non-detection time of time more than Tshort.Now, in the T0 time after this, timing obtains shorter nobody when determining the non-detection time of time more than Tshort, and be not in fact nobody, but the activity of people is less, the possibility that there is user is higher.Therefore, when the time of nobody being determined is set as that shorter nobody determines time Tshort, possessor to the greatest extent, running also can stop, and ease of use is impaired.Therefore, compared with determining time Tshort with shorter nobody, the time of preferably nobody being determined is set as that longer nobody determines time Tlong to control.Thus, the situation of movable less user can also be tackled.
Therefore, in the present embodiment, consider the action of the user shown in Fig. 7 B, as shown in Figure 8, first, set longer nobody and determine that time Tlong determines the initial value (step S1) of time as nobody during running beginning.
Then, every the T0 time, the judgement (step S2) that nobody determines the time is carried out.Now, during the T0 time, the maximum of T max of the non-detection time that clocking internal obtains is less than shorter nobody when determining time Tshort, nobody is determined time change is that shorter nobody determines time Tshort (step S3).
Then, when being judged to there is not user and the situation (step S4) that stopped the running of electric heater and the running that determined by the operation of operating portion 120 and timing function stop (step S5), nobody is determined time change is that longer nobody determines time Tlong.
Further, when again starting the running of electric heater, determine time Tlong according to longer nobody, again determine that nobody determines the time.
That is, in the present embodiment, as shown in Figure 8, in the running of electric heater, every the T0 time, the judgement determining the change of time Tshort to shorter nobody is only carried out.Further, the change determining time Tlong to longer nobody is only carried out when operating and stopping.Thus, determining that time Tshort carries out in the process operated in electric heater with shorter nobody, when there is not user, can reliably shut down.
In addition, be judged to be under the state that shorter nobody determines time Tshort, when using state change from the running midway of electric heater, the activity of user tail off, the change determining time Tlong to longer nobody can be carried out.Thereby, it is possible to prevent the situation that the running of electric heater frequently stops when there being people.
Such as, in the running of electric heater, if when timing obtain shorter nobody determine the non-detection time of time more than Tshort when, change to longer nobody and determine time Tlong, then determine time Tlong owing to being less than longer nobody non-detection time, therefore can not shut down.
In addition, change in using state midway, when the activity of user tails off, even if there is people, also frequently can produce the non-detection time that shorter nobody determines time more than Tshort.Therefore, if operate stop time, do not change to longer nobody and determine time Tlong, but maintain the setting that shorter nobody determines time Tshort, although then there is people, each running all can stop.Therefore, the ease of use of electric heater is impaired.In order to avoid this problem, as shown in Figure 8, after making running stop, determining the time as nobody, change to longer nobody and determine time Tlong.
As discussed above, the electric heater of present embodiment can according to the operating frequency of user, behaviour in service, nobody is determined the time accurately and easily automatically change at least shorter nobody and determine that time Tshort and longer nobody determine the Best Times such as time Tlong.
In addition, shorter nobody illustrated in present embodiment determines time Tshort, longer nobody determines that the optimum value of time Tlong, determination time T0 can be different according to the performance of human body sensor 311 and installation site.Therefore, in the present embodiment, implementing monitoring is tested, and considers that the balance of ease of use and economize on electricity property decides optimum value.Monitoring test as a result, average have people, the unmanned time be within 45 minutes per hour, have people, 15 minutes unmanned.According to this result, as mentioned above, specifically shorter nobody is determined that time Tshort is set as 3 minutes, longer nobody determines that time Tlong is set as 7 minutes, and determination time T0 is set as 7 minutes.But, be certainly not limited thereto.
Thus, compared with the situation not making running stop when electric heater and the human body sensor of present embodiment detect and there is not people, the power consumption of about 20% can be cut down.
As mentioned above, according to electric heater of the present invention, have: warm braw mechanism, it heats air; Body detecting part, it detects people; And human detection control part, it is according to the detection signal of body detecting part, judges the existence of people, does not exist, control running.Human detection control part 501 has: non-detection time measurement unit 511, it measures not having the time of detection signal; Unmanned detection unit 513, it judges not existing of people according to non-detection time; And nobody determines Time dependent portion 512, it determines the fiducial value being used for the unmanned non-detection time judged.Further, nobody determines the length of Time dependent portion 512 according to non-detection time, determines that nobody determines the time.Thereby, it is possible to according to operating frequency, the behaviour in service of user, nobody before shutting down is determined that time change is Best Times., most possessor can not be there is and be but judged to there is not people and the situation of the ease of use that to shut down etc., damage in its result.Further, power consumption when there is not people can be cut down.
In addition, electric heater according to the present embodiment, nobody determines the maximum of T max of Time dependent portion 512 according to the non-detection time in predetermined determination time T0, and the time of nobody being determined at least determines that to determine that time Tlong or shorter nobody determine in time Tshort one of any for longer nobody.Thereby, it is possible to according to operating frequency, the behaviour in service of user, easily and determine that best nobody determines the time exactly.
In addition, electric heater according to the present embodiment, nobody determines that the maximum of T max of the non-detection time of Time dependent portion 512 in predetermined determination time T0 is less than shorter nobody when determining time Tshort, nobody is determined Time dependent is that shorter nobody determines time Tshort.Thereby, it is possible to further easily and determine that shorter nobody determines time Tshort exactly.

(embodiment 2)
Below, the electric heater of Fig. 9 and Figure 10 to embodiment of the present invention 2 is used to be described.
Fig. 9 be illustrate in embodiment of the present invention 2 nobody determine the state transition diagram of the action in Time dependent portion.Figure 10 is the sequential chart of the motion of the electric heater that present embodiment is described.In addition, action when Figure 10 leaves after indoor stay about 1 minute for user, such as determine that time Tshort is 3 minutes, longer nobody determines the situation that time Tlong is 7 minutes, determination time T0 is 7 minutes, shows warm braw running and acts of determination for shorter nobody.In addition, in order to compare with present embodiment, the epimere of Figure 10 shows the action of the electric heater of embodiment 1.
That is, as shown in Figure 9, nobody when initial value and running start by the electric heater of present embodiment determines that the time is set as that shorter nobody determines time Tshort.And, following aspect is different from the electric heater of embodiment 1: after determining to there is not human body, determine that time Tlong and shorter nobody determine that the difference (being 4 minutes in Figure 10) of time Tshort is in the time longer nobody, when there is human detection signal, change to longer nobody and determine time Tlong.Other structures are identical with embodiment 1 with action etc., and therefore, detailed description quotes embodiment 1.
Below, Fig. 9 and Figure 10 is used to illustrate that nobody determines the determining method of time.
That is, as shown in Figure 10, the duration of runs of the warm braw mechanism of electric heater be indoor have people's time and nobody determine time sum.Specifically, as shown in the embodiment, if nobody when running being started determines that the time is set as that shorter nobody determines time Tshort, then the duration of runs be the indoor of 1 minute have people's time and 3 minutes nobody determine time sum, namely 4 minutes.
On the other hand, in embodiment 1, because nobody when running being started determines that the time is set as that longer nobody determines time Tlong, the indoor therefore becoming 1 minute the duration of runs have people's time and 7 minutes nobody determine time sum, namely 8 minutes.
Thus, compared with embodiment 1, the duration of runs of warm braw mechanism can be shortened.Therefore, the situation of the electric heater using present embodiment in the toilet of frequent no one or toilet etc. is particularly suitable for.Its result, can cut down power consumption when there is not people further.
Below, nobody in present embodiment is determined that the action of time detection unit is specifically described.
First, as shown in Figure 9, shorter nobody is determined that time Tshort is set as operating when starting nobody determine the initial value (step S1) of time.
Now, after the running of electric heater starts, when there is not human detection signal in during shorter nobody determines time Tshort, determine the time of the determination time T0 of time without nobody.Therefore, nobody determines that time detection unit 512 does not carry out determining that the change of time Tlong judges to longer nobody, but is judged to be no one, stops the running of electric heater.
About this state, following situation can be considered: the situation really leaving indoor and no one; And in fact in indoor, but during shorter nobody determines time Tshort in there is no the situation of movable, that operating frequency is lower user.In the latter case, if stop the running of electric heater continually when user is in indoor, then ease of use is poor.Therefore, need nobody to determine that time change is that longer nobody determines time Tlong.
In addition, no one is judged to be when being in indoor and operating frequency is lower, after running stops, again movable in during than the short period, human detection signal therefore detected.
Therefore, in the present embodiment, after determining to there is not human body, when longer nobody determines that time Tlong and shorter nobody determine that the difference (Tlong-Tshort) of time Tshort detects human detection signal in the time (step S2), nobody is determined time change is that longer nobody determines time Tlong (step S3).
Then, every the T0 time, the judgement (step S4) that nobody determines the time is carried out.Now, during the T0 time, the maximum of T max of the non-detection time that clocking internal obtains is less than shorter nobody when determining time Tshort, nobody is determined time change is that shorter nobody determines time Tshort (step S1).
In addition, under the state of step S3, be judged to be to there is not user, and when stopped the running of electric heater (step S5), and the running to be determined by the operation of operating portion 120 and timing function is when stopping (step S6), nobody is determined time change is that shorter nobody determines time Tshort.
Further, when again starting the running of electric heater, determining time Tshort according to shorter nobody, again determining that nobody determines the time.
As mentioned above, according to the present embodiment, the working time of warm braw mechanism can be shortened.Therefore, it is possible to reduce power consumption further.Especially, in the toilet of frequent no one or toilet etc., energy-saving can be realized further.On the other hand, as parlor or child room etc., usually when the indoor time is longer and operating frequency is lower, can prevent the running of electric heater from frequently stopping.Its result, can realize the electric heater of ease of use excellence further.
