Description
The present invention relates to electric dust collector.In more detail, just relate to show whether the amount of the rubbish of suction reaches the electric dust collector of specified amount.
Electric dust collector (after, abbreviate dust catcher as) along with the amount of the rubbish that sucks this body of dust collector inside increases, air is to will become obstructed (the aeration resistance increase) of flowing of the electric blowing machine of body of dust collector inside, so, the load that is added on the electric blowing machine alleviates, thereby the current value that flows through electric blowing machine reduces.Like this, utilize the amount of rubbish that reduces just to show suction of current value to reach specified amount (after, abbreviate rubbish as and show).The dust catcher with rubbish Presentation Function that has earlier is that the designated value that will flow through the current value of electric blowing machine is defined as threshold value, detects the electric current that flows through electric blowing machine, just carries out rubbish and show when current value is reduced to less than above-mentioned threshold value.
But, inhalation power that the operator can make dust catcher by the operation hand switch by the order of inhalation power intensity for example by " high-power ", " by force ", " in ", in the dust catcher of " weak " isotype variation, carry out this rubbish when showing, following misoperation takes place sometimes.Promptly, when not only the amount of the rubbish in being drawn into dust catcher surpasses specified amount and inhalation power is set at " in " when reaching " weak ", owing to compare the electric current that flows through electric blowing machine when " high-power " reaches " by force " and also reduce with being set at, so, at this moment in the dust catcher of rubbish Presentation Function with method that utilization has earlier, because pattern is the electric current that benchmaring flows through electric blowing machine with the situation of " by force ", so, just judge that the electric current that flows through electric blowing machine has reduced, thus will carry out with the amount of the rubbish that sucks irrespectively rubbish show.
Therefore, considered each pattern is set a reference value, but, when making electric dust collector when running and causing that owing to the user mode of other electric devices that use within the family or certain reason the voltage of supplying with family reduces etc., the supply voltage of supplying with electric blowing machine will reduce, thereby current value also reduces.At this moment, can judge that also the amount that is drawn into the rubbish in the dust catcher has surpassed specified amount, show thereby carry out rubbish.
The present invention proposes in order to address these problems, just purpose is carried out the dust catcher that rubbish shows reliably when aiming to provide a kind of current value that only surpasses specified amount and electric blowing machine in the amount of the rubbish that sucks less than threshold value.
In dust catcher of the present invention has the dress electric blowing machine have simultaneously dust storage chamber body of dust collector, detect the electric current flow through above-mentioned electric blowing machine current detecting part, have the supply voltage test section that detects supply voltage power circuit part, show the rubbish display unit of the quantity of refuse in the above-mentioned dust storage chamber and control the control circuit portion of above-mentioned rubbish display unit according to the output of above-mentioned current detecting part and power circuit part.
Above-mentioned rubbish display unit is not just carried out rubbish at the current value that is detected by the current detecting part of the electric current that flows through above-mentioned electric blowing machine during greater than specified threshold value and is shown, owing to can correctly carry out the rubbish demonstration, so be very desirable.
According to dust catcher of the present invention, because power circuit part has the supply voltage test section, so, when supply voltage itself reduces,, show with regard to not carrying out rubbish as long as current value is not less than specified threshold value.
Fig. 1 is the key diagram of an embodiment of expression dust catcher of the present invention.
Fig. 2 is the structured flowchart of circuit of an embodiment of expression dust catcher of the present invention.
Below, with reference to description of drawings dust catcher of the present invention.
Fig. 1 is the key diagram of outward appearance of expression dust catcher of the present invention, and Fig. 2 is the structured flowchart of circuit of an embodiment of expression dust catcher of the present invention.As shown in Figure 1, dust catcher of the present invention is made of the body of dust collector 16 and the suction device 17 of interior dress electric blowing machine (not shown).Flexible pipe 17b, prolongation pipe 17c are connected with its suction inlet with attraction tool 17d with the DYN dynamic floor with power brush (roll brush).Manual lever 17a with hand switch 15 is located at the leading section of flexible pipe 17b.By operating the revolution that these hand switch 15 controls are arranged on the electric blowing machine in the body of dust collector 16.Suction device 17 is made of with attraction tool 17d above-mentioned manual lever 17a, flexible pipe 17b, prolongation pipe 17c and floor.
Below, with reference to Fig. 2 circuit structure in the body of dust collector of the present invention 16 is described.In Fig. 2, the 1st, power circuit part, the transformer 1a, supply voltage test section 2 and the mu balanced circuit portion 3 that are used by step-down constitute.The elementary input of transformer 1a is promptly distributed to the circuit of motor (after, be called body motor 18a) of electric blowing machine and the circuit of power brush from the input of AC power 11.The circuit of body motor 18a is made of control element 4a, body motor 18a and current detecting part 6, and the electric current that flows through body motor 18a is detected by current detecting part 6.The current signal input microprocessor 5 of current detecting part 6.For example by TRIAC formations such as (trade name, the triode ac switch of General Electric Co. Limited (U.S.) system), the output of control element 4a is transfused to microprocessor 5 to control element 4a.The circuit of power brush is made of the motor 15a of control element 4b and power brush.
The secondary voltage of transformer 1a is measured by supply voltage test section 2, and the value of measurement is as power supply voltage signal input microprocessor 5.By operation hand switch 15 change " high-power ", " by force ", " in ", " weak " isotype, the result, the secondary voltage of transformer just changes.Like this, power supply voltage signal just changes accordingly with the switching of pattern.This power supply voltage signal compares in microprocessor 5 with the current signal of the current detecting part of importing when the above-mentioned control element 4a conducting 6.This comparative example is shown in table 1.The threshold value of supply voltage, power supply voltage signal and current signal when table 1 shows " high-power " pattern respectively.Table 1
| Supply voltage [V] | Power supply voltage signal [V] | Current signal [V] |
| Greater than 105 | ????5.0～4.75 | ????2.5 |
| Greater than 100 less than 105 | ????4.75～4.50 | ????2.3 |
| Greater than 95 less than 100 | ????4.50～4.25 | ????2.2 |
| Less than 95 | ????4.25～0 | ????2.0 |
For example, power supply voltage signal less than 5.0V greater than 4.75V (promptly, the about 110V of supply voltage) time, under the state that rubbish does not overstock, the current signal that is detected by current detecting part 6 is about 2.7V, so, as long as the current signal that detects is less than 2.5V, microprocessor 5 just judgement has overstock rubbish, thereby makes rubbish show that LED7 lights.In addition, when power supply voltage signal less than 4.25V during when (, the about 90V of supply voltage) greater than 0V, under the state that rubbish overstocks, the current signal that is detected by current detecting part 6 is about 2.5V.Like this, big by when supply voltage is big, the threshold value of above-mentioned current signal being set, hour the threshold value of above-mentioned current signal is set for a short time when supply voltage, just can carry out the correct rubbish corresponding and show with the reduction of supply voltage.
In addition, the secondary voltage of transformer 1a stabilizes to for example 5V of certain voltage by mu balanced circuit portion 3, and supplies with microprocessor 5.Rubbish shows LED7, shows the corresponding dummy resistance 8 of LED7 and be connected with microprocessor 5 with the corresponding dummy resistance 9 of power brush with rubbish, to the certain voltage of their supply direct currents, for example 5V.Because the electric current that electric current by dummy resistance 8 and rubbish flow through when showing lighting of LED7 is identical, so, for example when the resistance that uses about 510 Ω and rubbish when showing that LED7 lights, the port of microprocessor 5 becomes high level, and promptly dummy resistance 8 becomes the state of obstructed overcurrent.On the contrary, when rubbish showed that LED7 does not light, the port of microprocessor 5 just became low level, thereby dummy resistance 8 passes through electric current.Equally, when power brush conducting (the control element 4b conducting of connection), become high level with regard to the port that makes microprocessor 5, that is, dummy resistance 9 obstructed overcurrent become low level with regard to the port that makes microprocessor 5 when power brush cuts off the power supply.Here, show that by microprocessor 5, control element 4a and 4b, current detecting part 6, rubbish LED7 and dummy resistance 8,9 constitute control circuit portion (not shown).
Like this, by connecting dummy resistance 8 and 9, no matter rubbish shows LED7 and power brush energising or outage, always can make the load of power circuit keep certain, the output of current detecting part 6 diminishes when power brush is switched on, thereby can not carry out the misoperation that rubbish shows.
Above-mentioned table 1 is an example only, and the kind of pattern and the threshold value of each pattern can suitably be selected.According to dust catcher of the present invention, the rubbish whether amount of the rubbish that can correctly suck according to the amount of rubbish has reached specified amount shows.
