Hereinafter, being illustrated to the action of the human testing control unit of present embodiment using Fig. 5.
Fig. 5 is the flow chart for the action for illustrating the human testing control unit in present embodiment.In addition, human testing controls
Portion 501 executes process flow shown in fig. 5 every certain sampling time.
As shown in figure 5, first, the confirmation of non-detection time measurement unit 511 of human testing control unit 501 has human body inspection of having no way of
The signal (step S1) that survey portion 301 exports.Not from body detecting part 301 export signal in the case of (step S1's
"No"), timing (step S2) is carried out to the non-detection time.Also, to people until body detecting part 301 detects human body
Sigtnal interval, i.e. signal non-detection status (state of the no signal) duration (non-detection time) that signal is surveyed in physical examination carries out
Measurement.At this point, in the case where detecting human body by body detecting part 301 ("Yes" of step S1), (reset) non-detection is removed
The timing (step S3) of time.Start the detection of new non-detection time as a result,.
Then, the unmanned of human testing control unit 501 determines time determination section 512 according to the aftermentioned unmanned determining time
Determining method determines unmanned determining time (step S4).
Then, the unmanned determination unit 513 of human testing control unit 501 compares non-detection time and unmanned determining time
Compared with (step S5).At this point, when the non-detection time continue for the unmanned time determined more than the time ("Yes" of step S5), judgement
For human body (step S6) is not present.In turn, indicate that operating stops or economize on electricity operates 1 (step S7) to main body control portion 401.Separately
On the one hand, in the case where the non-detection time being less than the unmanned determining time ("No" of step S5), it is determined to have human body (step
S8).In turn, it indicates usually to operate (step S7) to main body control portion 401.
Also, during electric heater 100 is worked, above-mentioned action repeatedly detects human body.
Hereinafter, being illustrated to the specific action of the electric heater of present embodiment with reference to the flow chart of figure 5, and using Fig. 6.

As shown in fig. 6, first, in the case where human testing control unit 501 determines that human body is not present, present embodiment
Electric heater make operating condition from usually be transferred to economize on electricity operate 1.That is, not deposited when human testing control unit 501 determines
In human body, stop operating as the warm wind of warm air function, continues to operate as the humid control of humidification function.
At this point, humidification function reduces target humidity and carries out low humidity control operating.As a result, when nobody, it can inhibit
With the lasting power consumption increase for carrying out common humidification operating and correspondingly causing.But in low humidity control operating, if excessively
Target humidity is reduced to want until being restored to the comfort humidity as the target humidity usually operated then when operating restarts
Spend more time.Therefore, in the present embodiment, such as by the target humidity usually operated it is set as about 55%, by nothing
Target humidity when people is set as about 40% low humidity.
Then, in the state of carrying out operating control with economize on electricity operating 1, when people is re-introduced into interior, by human testing
Control unit 501 determines that there are people.Electric heater is worked with usual drive manner again as a result,.
In addition, in the case of the electric heater without humidification mechanism, when determining, there is no when people, stop being used as warm wind
The warm wind of function operates.Also, the state is maintained, until detecting human body by body detecting part 301 next time.
<4>The unmanned determining method for determining the time
Hereinafter, determining that the determining method of time illustrates to unmanned shown in Fig. 5 using Fig. 7 A to Fig. 8.
Fig. 7 A and Fig. 7 B are the signal detection states that the body detecting part in present embodiment is shown according to time series
Figure.Fig. 8 is the state transition diagram for illustrating the unmanned action for determining time determination section in present embodiment.
That is, as described in Figure 5, it is unmanned to determine that time determination section 512 determines to determine as the unmanned of fiducial value
The case where time, the fiducial value were used for according to the non-detection time detected in step s 2, and human body is not present in judgement.
Fig. 7 A and Fig. 7 B are specifically used, signal detection when having used electric heater under different use states is compared
State, while illustrating the unmanned determining method for determining the time.
In addition, the unmanned decision for determining the time is judged from operation start every judgement time T0.At this point, in this reality
It applies in mode, the maximum value for the non-detection time that timing obtains in a period of the T0 times is set as Tmax, determined unmanned
Time shorter unmanned determines that the time is set as Tshort (such as 3 minutes), unmanned determines that the time is set as Tlong by longer
(such as 7 minutes).
First, under the use state of electric heater shown in Fig. 7 A, as someone, within the T0 times, it is shorter to be timed
Unmanned determine that the non-detection time more than time Tshort does not have once yet.At this point, in T0 times after this, timing obtains
In the case of having arrived the shorter unmanned non-detection time determined more than time Tshort, if it is the use of same electric heater
State, the then possibility that user is not present are higher.It is therefore preferable that when the unmanned determination time is set as shorter unmanned determination
Between Tshort controlled.
On the other hand, under the use state of electric heater shown in Fig. 7 B, even if someone, within the T0 times, there is also quilts
Timing is the shorter unmanned non-detection time determined more than time Tshort.At this point, in T0 times after this, timing obtains
In the case of having arrived the shorter unmanned non-detection time determined more than time Tshort, not actually nobody, but
The activity of people is less, there is a possibility that user is higher.Therefore, the unmanned determination time is being set as shorter unmanned determination
When time Tshort, although someone, operating can also stop, and ease of use is impaired.Therefore, unmanned the time is determined with shorter
Tshort is compared, and the unmanned determining time is preferably set as longer unmanned determining time Tlong to control.As a result, also
The case where coping with activity less user.
Therefore, in the present embodiment, consider the action of user shown in Fig. 7 B, as shown in figure 8, first, setting compared with
The unmanned initial value (step S1) for determining time when long unmanned determining time Tlong is as operation start.
Then, every the T0 times, the unmanned judgement (step S2) for determining the time is carried out.At this point, in a period of the T0 times
In the case that the maximum of T max for the non-detection time that timing obtains is less than shorter unmanned determining time Tshort, really by nobody
It fixes time and is changed to shorter unmanned determining time Tshort (step S3).
Then, it is being determined as there is no user and the case where stopped the operating of electric heater (step S4) and by grasping
Make the operation in portion 120 and in the case that operating that timing function determines stops (step S5), by it is unmanned determine the time be changed to compared with
Long unmanned determining time Tlong.
Also, when starting again at the operating of electric heater, according to longer unmanned determining time Tlong, nobody is determined again
Determine the time.
