Definitions
- the invention relates to a method according to the preamble of claim 1 and a handheld air shower according to the preamble of claim 9.
- a method according to the preamble of claim 1 or a hand-held air shower according to the preamble of claim 9 is known for example from DE-A-25 35 853.
- the disadvantage is that the hot air flow hitting the object can have very different temperature values depending on the distance of the object / warm air flow outlet opening of the hand-held air shower. In order to substantially avoid this disadvantage, it depends very much on the skill of a user of the hand-held air shower to take the required distance in relation to the desired - emotionally dependent - temperature of the hot air flow hitting the object. This is made even more difficult if heating outputs of different heights are set, because this necessarily changes the required distance.
- This object is achieved according to the characterizing part of claim 1 and claim 9.
- Figure 1 shows a principle of operation of the method or the handheld air shower
- FIG. 2 shows a block diagram for controlling a heating device
- FIG. 3 shows a block diagram for controlling a heating device
- FIG. 4 shows a diagram of a heating output as a function of the distance
- FIG. 5 shows a diagram of a heating and blower output as a function of the distance
- FIG. 6 shows a block diagram as in FIG. 3, but additionally with a device for detecting that the distance detection range has been exceeded;
- FIG. 7 shows a distance detection device
- Figure 8 is a block diagram of the device of Figure 7;
- Figure 9 is a block diagram of an object size detection device.
- the heating device 4 depending on the distance S is controlled proportionally, so that a predetermined temperature of the warm air flow 2 to the object 1 remains largely independent of the distance between the warm air outlet opening 8 of the hand-held air shower 3 and the object 1.
- the heating device 4 is controlled by means of distance measurement values S 1, S 2, S 3, S 4 of a distance detection device 7, wherein the principle of the sound propagation time can be provided for detecting the distance S, as described for example in WO 91/18534.
- a reflected light method according to FIGS. 7 and 8 can also be used.
- the relationship between a heating power P and the distance S at a predetermined temperature is shown in the diagram, the steepness of the curve 9 (the heating power P changes approximately square to the distance) depends on the maximum heating power Pj_ of a handheld air shower 3.
- the heating power P2 is controlled disproportionately to the distance S, because in the close range the warm air flow 2 contributes disproportionately to drying.
- the distance detection device 7 is coupled to a signal device 10.
- the blower 5 is also controlled proportionally to the distance S.
- a further harmonization of the drying effect as a function of the distance S is achieved in that the heating power P is changed proportionally depending on the size D of the object 1 to be treated, since at the same distance S4 a smaller object 1 has less heating power P (and less Warm air flow 2) is required as a larger object 1.
- FIG. 2 shows a block diagram of a hand-held air shower 3 with a heating device 4 connected to a power control device 11 and a blower 5 (FIG. 1) for treating an object 1 by means of a hot air stream 2 directed at the object.
- the hand-held air shower 3 is provided with a distance detection device 7, which has an output 12 for determined distance measured values Si, S2, S3, S4, a comparison device 13 being used to make a proportional selection from the distance measured values Si, S2 S3, S4 and a predetermined temperature value of a temperature selection device 14 Control signals are formed for controlling the power control device 11.
- the comparison device 13 is connected to an ambient temperature sensor 15 in order to be able to take into account the ambient temperature and fluctuations.
- the temperature value specified by the comparison device 13 is set Corresponding hot air temperature sensor 16 is provided, which is connected to a controller 17.
- an output signal 18 of the power control device 11 is connected at a branching point 19 via a negative feedback path 20 to the comparison device 13 in negative feedback, the warm air temperature at the outlet opening 8 being regulated to the temperature value specified by the comparison device 13.
- the specified temperature value is corrected accordingly.
- the respective predefined temperature value is integrated as a table in the comparison device 13 and is derived from the parameters of the temperature selection device 14, the distance to the object 1, the ambient temperature and the maximum heating power P.
- the diagram according to FIG. 5 shows a curve profile 9 of the heating power P as a function of the distance S and, proportionally thereto, the curve profile 23 of the power control of the blower 5, as a result of which a more appropriate drying of head hair is achieved.
- a device 24 for detecting an exceeding of the distance detection area S4 is provided, to which a signal device 10 is coupled, the device 24 being integrated in a table in the comparison device 13. It can be provided that when the detection range S4 is exceeded The heating device 4 is switched off, advantageously only when the object 1 is not again in the detection area S4 within a predetermined period of time.
- a time delay device 26 is provided with a reset device 27, which is activated when the object 1 is again in the detection area S4 within a predetermined period of time.
- the time delay device 26 is connected on the one hand to the overrun device 24 and on the other hand to the power control part 11.
- the signal device 10 - as indicated by dashed lines - is connected to the output of the time delay device 26, a signal is given only when the heating device 4 is switched off.
- the fan 5 is also proportionally provided by means of a fan control device 28 to control.
- the distance detection device 7 according to FIG. 1 can be provided with an ultrasound transmission device 29 and an ultrasound reception device 30, the transit time of the reflected ultrasound waves 31 being used to measure the (relative) distance S.
- FIG. 7 An independent exemplary embodiment of the distance detection device 7 by means of an infrared light transmitter device 32 and an infrared reflex light receiver device 33 is shown in FIG.
- the principle of the distance detection is that the transmitter 32 and the receiver 33 are arranged at a basic distance from one another, and that the IR light rays 34 ... 38 reflected by an object 1 are selectively identified on the basis of their light intensity and a certain distance S_, S2, S3, S4, S5 can be assigned.
- This can be realized, for example, by the transmitter 32 having a series of IR transmit diodes 39 ... 43 is provided, each IR transmit diode 39 ... 43 being oriented at a certain angle of incidence alphai ...
- the IR transmit diodes 39 ... 43 and the IR receive diodes 45 ... 49 are cyclically controlled synchronously in a time-division multiplex method (FIG. 8).
- the multiplexer 55 and the comparator 57 are clocked synchronously by a timer 56. If a maximum signal value is determined for a specific cycle, the comparator 57 assigns this to a corresponding distance S.
- the IR reflected light beam 36 is identified as the maximum value and assigned to the distance S3. With two adjacent maximum values, the comparator 57 assigns this to a corresponding mean value of the distance S. It goes without saying that as the number of IR transmit or receive diodes increases, a finer stage measurement can be carried out.
- the object size detection device 58 is provided to feed the received signals 64 to the distance detection device 7 and a signal strength detection device 61, whereby an object size detection logic 62 determines a corresponding object size signal 63 from the determined distance S and the signal strength, which is fed to the comparison device 13 - in Combination with the examples according to FIGS. 2 or 3 or 6 - for controlling / regulating the heating device 4 via the power control device 11.
