Abstract
電動吸塵器共用從電源線往電源電路之電源供給路徑，及從2次電池往電源電路之電流供給路徑之一部分，並且在從2次電池往電源電路之電源供給路徑設置半導體開關元件。接著，沒有來自交流電源之電力供給時，藉由將觸發電路用電源作為電源之操作輸入而開啟半導體開關元件並且使電源電路啟動。另一方面，在沒有操作輸入時，可從2次電池供給電源至觸發電路用電源。藉此，可減少2次電池之消耗電力，並且可實現防止2次電池之容量降低或性能劣化。 The electric vacuum cleaner shares a power supply path from the power supply line to the power supply circuit, and a part of the current supply path from the secondary battery to the power supply circuit, and a semiconductor switching element is provided in the power supply path from the secondary battery to the power supply circuit. Next, when there is no power supply from the AC power source, the semiconductor switching element is turned on and the power supply circuit is activated by using the power supply for the trigger circuit as an operation input of the power source. On the other hand, when there is no operation input, the power can be supplied from the secondary battery to the power supply for the trigger circuit. Thereby, the power consumption of the secondary battery can be reduced, and the capacity reduction or performance degradation of the secondary battery can be prevented.
Description
本發明是有關於一種在商用電源與2次電池之兩者動作之交流直流兩用的電動吸塵器。 The present invention relates to an AC-DC electric vacuum cleaner that operates in both a commercial power source and a secondary battery.
以往，可選擇性地切換交流電源與直流電源(2次電池)而運轉之電動吸塵器是揭示於例如特開2001-321307號公報(以下，記為專利文獻1)。專利文獻1記載之交流直流兩用之電動吸塵器藉由交流頻率信號(以下，記為「Hz信號」)的有無，選擇性地切換交流電源與直流電源(2次電池)。而且，將電源供給至用以控制控制電路之控制電路用電源電路。 In the related art, an electric vacuum cleaner that can selectively switch between an AC power source and a DC power source (secondary battery) is disclosed in Japanese Laid-Open Patent Publication No. 2001-321307 (hereinafter referred to as Patent Document 1). The AC-DC electric vacuum cleaner described in Patent Document 1 selectively switches between an AC power source and a DC power source (secondary battery) by the presence or absence of an AC frequency signal (hereinafter referred to as "Hz signal"). Further, power is supplied to the power supply circuit for the control circuit for controlling the control circuit.
然而，專利文獻1揭示之習知之電動吸塵器的構成是，當檢測到已無Hz信號時，則以2次電池供給電源至控制電路用電源電路。此種情況下，當電動吸塵器未運轉時(包含收納時)也會供給電源至控制電路用電源電路。因此，會經常消耗2次電池之電力，2次電池之電池容量會降低。 However, the conventional vacuum cleaner disclosed in Patent Document 1 is configured to supply a power source to a power supply circuit for a control circuit in a secondary battery when it is detected that there is no Hz signal. In this case, when the electric vacuum cleaner is not operating (including storage), the power is supplied to the power supply circuit for the control circuit. Therefore, the battery power is often consumed twice, and the battery capacity of the second battery is reduced.
因此，若在一定期間內未以2次電池使用電動吸 塵器之使用者以2次電池使電動吸塵器運轉，則會有運轉時間變短的問題。進而，在長期保管之情況下，2次電池會成為過放電狀態。因此，會有2次電池之壽命降低之虞。 Therefore, if you do not use electric suction for 2 times in a certain period of time When the user of the duster operates the electric vacuum cleaner with the secondary battery, the operation time becomes short. Further, in the case of long-term storage, the secondary battery is in an overdischarged state. Therefore, there will be a decrease in the life of the battery twice.
本發明提供一種可防止2次電池之容量降低或性能劣化之電動吸塵器。 The present invention provides an electric vacuum cleaner that can prevent a decrease in capacity or performance of a secondary battery.
也就是說，本發明之電動吸塵器包含有：吸塵器本體；把手部；及設置於前述把手部並且輸入運轉操作之操作輸入受理部，在前述吸塵器本體內至少具有：電動送風機；可連接於交流電源之電源線；2次電池；用以檢測前述電源線有無連接於前述交流電源之Hz信號檢測部；藉由前述電動送風機之控制及前述Hz信號檢測部進行檢測之信號控制部；前述信號控制部之電源電路；從前述2次電池供給電源之觸發電路用電源；及令前述觸發電路用電源為電源之觸發電路，從前述電源線往前述電源電路之電源供給路徑，與從前述2次電池往前述電源電路之供給路徑之一部分共用，並且設置半導體開關元件作為從前述2次電池往前述電源電路之前述電源供給路徑的開閉部，當來自前述交流電源之電力供給中斷時，藉由將來自前述操作輸入受理部之前述觸發電路用電源作為電源之操作輸入之來自前述觸發電路之主電源啟動信號，前述半導體開關元件開啟，並且前述電源電路啟動而前述信號控制部開始運轉，並且在未操作輸入時僅由前述2次電池供給電源至前述觸發電 路用電源。 That is, the electric vacuum cleaner of the present invention includes: a vacuum cleaner body; a handle portion; and an operation input receiving portion provided in the handle portion and inputting an operation operation, and having at least an electric blower in the cleaner body; and being connectable to an AC power source a power supply line; a secondary battery; a Hz signal detecting unit for detecting whether or not the power supply line is connected to the AC power source; and a signal control unit for detecting by the control of the electric blower and the Hz signal detecting unit; and the signal control unit a power supply circuit; a power supply for a trigger circuit for supplying power from the secondary battery; and a trigger circuit for powering the power supply for the trigger circuit, a power supply path from the power supply line to the power supply circuit, and a secondary power supply from the secondary battery One of the supply paths of the power supply circuit is shared, and a semiconductor switching element is provided as an opening/closing portion of the power supply circuit from the secondary battery to the power supply circuit, and when power supply from the AC power supply is interrupted, Operating the power supply for the trigger circuit of the input receiving unit Inputting a main power activation signal from the trigger circuit for operation of the power source, the semiconductor switching element is turned on, and the power supply circuit is activated and the signal control unit starts to operate, and when the input is not operated, only the secondary battery is supplied with power to Trigger power Road power supply.
根據該構成，若電源供給由交流電源切換成2次電池，在沒有操作輸入之來自觸發電路之主電源啟動信號之期間，不供給電力至電源電路。藉此，在無負荷時，可僅供給電源至消耗電力極小之觸發電路用電源。其結果是，可減少2次電池之電池容量降低。又，可抑制因長期保管之2次電池的過放電。其結果是，可實現信賴性優異之電動吸塵器。 According to this configuration, when the power supply is switched from the AC power source to the secondary battery, the power is not supplied to the power supply circuit while the main power supply activation signal from the trigger circuit is not input. Thereby, when there is no load, only the power supply can be supplied to the power supply for the trigger circuit which consumes extremely little power. As a result, the battery capacity reduction of the secondary battery can be reduced. Moreover, overdischarge of the secondary battery stored for a long period of time can be suppressed. As a result, an electric vacuum cleaner excellent in reliability can be realized.

以下，參照圖式說明本發明之實施形態。再者，本發明不受該實施形態而限定。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Furthermore, the present invention is not limited to the embodiment.
以下，使用圖1說明本發明之實施形態之電動吸塵器。 Hereinafter, an electric vacuum cleaner according to an embodiment of the present invention will be described with reference to Fig. 1 .
圖1是顯示本發明之實施形態之電動吸塵器之外觀的立體圖。如圖1所示，本實施形態之電動吸塵器至少由內部設有電動送風機之吸塵器本體1、電源線2、軟管3、把手4、把手操作部5(把手開關部)、延長管6、及地面吸入具7等所構成。電源線2將例如商用電源等之交流電源供給 至吸塵器本體1。軟管3連接於吸塵器本體1。把手4連通，連接於軟管3。把手操作部5設置於把手4。延長管6連通，連接於把手4。地面吸入具7連通，連接於延長管6。 Fig. 1 is a perspective view showing the appearance of an electric vacuum cleaner according to an embodiment of the present invention. As shown in Fig. 1, the vacuum cleaner of the present embodiment includes at least a cleaner body 1 including an electric blower, a power cord 2, a hose 3, a handle 4, a handle operating portion 5 (handle switch portion), an extension tube 6, and The ground suction device is composed of 7 or the like. The power supply line 2 supplies an AC power source such as a commercial power source To the vacuum cleaner body 1. The hose 3 is connected to the cleaner body 1. The handle 4 is connected to and connected to the hose 3. The handle operating portion 5 is provided to the handle 4. The extension tube 6 is in communication and is connected to the handle 4. The ground suction device 7 is connected and connected to the extension pipe 6.
又，吸塵器本體1在內設有或外裝有由2次電池等之蓄電池構成之直流電源。 Further, the cleaner body 1 is provided with or has a DC power source composed of a battery such as a secondary battery.
以下，說明本實施形態之電動吸塵器的動作。 Hereinafter, the operation of the electric vacuum cleaner of the embodiment will be described.
首先，藉由交流頻率信號之有無，判定以交流電源或直流電源之何者驅動電動送風機。 First, it is determined by which the AC power source or the DC power source drives the electric blower by the presence or absence of the AC frequency signal.
其次，根據判定結果，藉由把手操作部5之運轉指示開關之操作，以交流電源或直流電源使電動送風機旋轉。藉此，由地面等之清掃面從地面吸入具7吸入空氣流與塵埃。接著，從地面吸入具7吸入之塵埃經由延長管6，把手4，軟管3而導入並集塵於吸塵器本體1內之集塵室。 Then, based on the result of the determination, the electric blower is rotated by the AC power source or the DC power source by the operation of the operation instruction switch of the handle operating portion 5. Thereby, the airflow and the dust are taken in from the ground suction device 7 by the cleaning surface of the ground or the like. Then, the dust sucked from the floor suction device 7 is introduced into the dust collecting chamber in the cleaner body 1 through the extension pipe 6, the handle 4, and the hose 3.
本實施形態之電動吸塵器如上所構成，並且動作。 The electric vacuum cleaner of this embodiment is configured as above and operates.
以下，使用圖2說明本實施形態之電動吸塵器之控制。 Hereinafter, the control of the electric vacuum cleaner of this embodiment will be described using FIG.
圖2為同實施形態之電動吸塵器的電路圖。再者，圖2主要是顯示本實施形態之電動吸塵器之電源控制系。 Fig. 2 is a circuit diagram of the electric vacuum cleaner of the same embodiment. Further, Fig. 2 mainly shows a power supply control system of the electric vacuum cleaner of the embodiment.
如圖2所示，電動吸塵器之電源控制系由：交流電源11(商用電源)，構成直流電源之2次電池12，操作輸入受理部18，構成信號控制部之微型電腦19(以下，記為「微電腦」)，構成主電源之電源電路13，Hz信號檢測部14、主電源啟動電路15、觸發電路用電源16、觸發電路17等構 成。操作輸入受理部18受理來自把手操作部5之輸入信號。微電腦19統括控制系統全體。電源電路13將電源供給至微電腦19等。Hz信號檢測部14檢測交流頻率信號(Hz信號)之有無。主電源啟動電路15與電源電路13串聯，用以開啟/關閉由2次電池往電源電路13之電源的供給。具體而言，主電源啟動電路15藉由後述之主電源啟動信號而開啟/關閉半導體開關元件20，實現上述動作。 As shown in Fig. 2, the power supply control of the vacuum cleaner is composed of an AC power supply 11 (commercial power supply), a secondary battery 12 constituting a DC power supply, an operation input receiving unit 18, and a microcomputer 19 constituting a signal control unit (hereinafter, "Microcomputer", the power supply circuit 13, which constitutes the main power supply, the Hz signal detecting unit 14, the main power starting circuit 15, the power supply circuit 16 for the trigger circuit, and the trigger circuit 17 to make. The operation input accepting unit 18 accepts an input signal from the handle operating unit 5. The microcomputer 19 integrates the entire control system. The power supply circuit 13 supplies power to the microcomputer 19 or the like. The Hz signal detecting unit 14 detects the presence or absence of an alternating current frequency signal (Hz signal). The main power source starting circuit 15 is connected in series with the power source circuit 13 for turning on/off the supply of the power source from the secondary battery to the power source circuit 13. Specifically, the main power source activation circuit 15 turns on/off the semiconductor switching element 20 by a main power source activation signal, which will be described later, to achieve the above operation.
又，觸發電路用電源16藉由2次電池12供給電源，負責後述之主電源啟動信號之電源供給。具體而言，觸發電路用電源16為了極為減少無負荷時之電池的消耗電力，是由漏電流2μA以下(2次電池12之電池電壓為50.4V時)之電源電路構成。再者，觸發電路用電源16若在本實施形態是相對於電源線路A輸出-20V。 Further, the trigger circuit power supply 16 supplies power to the secondary battery 12, and is responsible for the power supply of the main power supply start signal to be described later. Specifically, the trigger circuit power supply 16 is configured by a power supply circuit having a leakage current of 2 μA or less (when the battery voltage of the secondary battery 12 is 50.4 V) in order to extremely reduce the power consumption of the battery when no load is applied. Further, in the present embodiment, the trigger circuit power supply 16 outputs -20 V with respect to the power supply line A.
觸發電路17以觸發電路用電源16為電源，而產生用以開啟主電源啟動電路15之半導體開關元件20之觸發信號。 The trigger circuit 17 generates a trigger signal for turning on the semiconductor switching element 20 of the main power starting circuit 15 with the power supply 16 for the trigger circuit as a power source.
其次，說明如上述構成之電動吸塵器之電源控制系的動作。 Next, the operation of the power supply control system of the electric vacuum cleaner configured as described above will be described.
首先，若是電源線2已拔除的狀態，則開啟主電源啟動電路15之半導體開關元件20。此時由2次電池12僅供給電源至無負荷時之2次電池之消耗電力極小之觸發電路用電源16。因此，構成信號控制部之微電腦19未有動作。 First, if the power supply line 2 has been removed, the semiconductor switching element 20 of the main power supply starting circuit 15 is turned on. At this time, the secondary battery 12 supplies only the power supply to the trigger circuit power supply 16 in which the secondary battery power consumption is extremely small. Therefore, the microcomputer 19 constituting the signal control unit does not operate.
接著，觸發電路用電源16將齊納二極體(Zener diode)32之齊納電壓，與藉由FET35(場效型電晶體：Field Effect Transistor)之臨界電壓(閾值電壓)決定之電壓輸出到輸出平滑電容器34之兩極間。再者，輸出平滑電容器34由例如電解電容器或陶瓷電容器等構成，將上述電壓之變動平滑化。此時，當以陶瓷電容器構成輸出平滑電容器34時，由於漏電流會變少，因此較佳。藉此，當在齊納電壓以下時，則停止觸發電路用電源16之動作。其結果是，可更為減少2次電池之電池容量之降低，及更為延長到過放電之時間。 Next, the trigger circuit uses the power source 16 to apply the Zener voltage of the Zener diode 32 to the FET 35 (Field Effect Transistor: Field) The voltage determined by the threshold voltage (threshold voltage) of the Effect Transistor is output between the two poles of the output smoothing capacitor 34. Further, the output smoothing capacitor 34 is composed of, for example, an electrolytic capacitor or a ceramic capacitor, and smoothes the fluctuation of the voltage. At this time, when the output smoothing capacitor 34 is constituted by a ceramic capacitor, leakage current is reduced, which is preferable. Thereby, when the Zener voltage is equal to or lower than the Zener voltage, the operation of the trigger circuit power supply 16 is stopped. As a result, the battery capacity reduction of the secondary battery can be further reduced, and the time until the overdischarge is further extended.
此時，觸發電路用電源16之電阻33是以例如1MΩ左右之高電阻設置，限制流通於齊納二極體32之電流。藉此，可極力減少無負荷時之電流，並且抑制2次電池12之消耗電力。 At this time, the resistor 33 of the power supply circuit 16 for the trigger circuit is provided with a high resistance of, for example, about 1 MΩ, and the current flowing through the Zener diode 32 is restricted. Thereby, the current at the time of no load can be reduced as much as possible, and the power consumption of the secondary battery 12 can be suppressed.
進而，觸發電路用電源16具有：限流電阻31，及二極體30。限流電阻31限制負荷電流。二極體30在電源線2連接到商用電源時，可防止電流從交流電源11經由2次電池12而流入。 Further, the trigger circuit power supply 16 has a current limiting resistor 31 and a diode 30. The current limiting resistor 31 limits the load current. When the power supply line 2 is connected to the commercial power source, the diode 30 can prevent current from flowing from the AC power source 11 via the secondary battery 12.
此時，操作輸入受理部18之開關52、53、54、55任一者開啟時，電流由電源線路A經由操作輸入受理部18流入觸發電路17之二極體41、電阻42、電晶體43之基極射極間。藉此，開啟電晶體43之集極射極間。接著，啟動主電源啟動電路15之主電源啟動信號流通。此時，電源電路13尚未啟動。因此，電流不會由觸發電路17經由二極體50而流入電阻51。 At this time, when either of the switches 52, 53, 54, and 55 of the operation input receiving unit 18 is turned on, the current flows from the power supply line A through the operation input receiving unit 18 to the diode 41 of the flip-flop circuit 17, the resistor 42, and the transistor 43. The base between the emitters. Thereby, the collector between the collectors of the transistor 43 is turned on. Next, the main power source start signal of the main power source starting circuit 15 is started. At this time, the power supply circuit 13 has not been started yet. Therefore, current does not flow into the resistor 51 via the diode 50 through the flip-flop circuit 17.
藉此，主電源啟動信號之電由電源線路A經由主 電源啟動電路15之電晶體21之基極射極間、電阻25、觸發電路17之電晶體43之集極射極間而流通。進而，電流流通於主電源啟動電路15之電晶體21之集極射極間、電阻22、電阻23。其結果是，主電源啟動電路15之半導體開關元件20啟動。 Thereby, the power of the main power start signal is transmitted from the power line A via the main The base-emitter of the transistor 21 of the power-start circuit 15 and the collector 25 between the resistor 25 and the transistor 43 of the flip-flop circuit 17 are circulated. Further, a current flows between the collector and the emitter of the transistor 21 of the main power source starting circuit 15, the resistor 22, and the resistor 23. As a result, the semiconductor switching element 20 of the main power source starting circuit 15 is activated.
當半導體開關元件20啟動時，電源供給至為主電源之電源電路13。藉此，電源電路13啟動時，也啟動微電腦19。 When the semiconductor switching element 20 is activated, power is supplied to the power supply circuit 13 of the main power source. Thereby, the microcomputer 19 is also activated when the power supply circuit 13 is activated.
其次，當微電腦19啟動時，微電腦19藉由Hz信號檢測部14判定交流頻率信號之輸入的有無。此時，若無輸入交流頻率信號，微電腦則判定為2次電池12進行之電源啟動。接著，微電腦19開啟觸發電路17之電晶體40而使電流從電源線路A開始流通於觸發電路17之電阻42、電晶體43之基極射極間。藉此，維持從2次電池12往電源電路13之電源供給。同時，藉由二極體41之陰極側成為與電源線路A相同之電壓，微電腦19接收預定之電壓。接著，因應於相當於微電腦19所接收之輸入信號之電壓，電動吸塵器會進行動作。在此，上述所謂之預定電壓，是將從電源電路13之輸出電壓減去二極體50之順方向電壓之電壓，以在操作輸入受理部18之已開啟的開關形成之電阻45、46、47、48所構成之合成電阻與電阻51分壓後之電壓。 Next, when the microcomputer 19 is activated, the microcomputer 19 determines the presence or absence of the input of the AC frequency signal by the Hz signal detecting unit 14. At this time, if the AC frequency signal is not input, the microcomputer determines that the power supply of the secondary battery 12 is started. Next, the microcomputer 19 turns on the transistor 40 of the flip-flop circuit 17 to cause a current to flow from the power source line A between the resistor 42 of the flip-flop circuit 17 and the base emitter of the transistor 43. Thereby, the power supply from the secondary battery 12 to the power supply circuit 13 is maintained. At the same time, the microcomputer 19 receives the predetermined voltage by the same voltage as the power supply line A on the cathode side of the diode 41. Next, the vacuum cleaner operates in response to the voltage corresponding to the input signal received by the microcomputer 19. Here, the predetermined voltage is a voltage obtained by subtracting the voltage of the forward direction of the diode 50 from the output voltage of the power supply circuit 13 to form the resistors 45 and 46 formed by the opened switch of the input receiving unit 18. 47, 48 composed of a composite resistor and a voltage after the resistor 51 is divided.
再者，操作輸入受理部18之開關開啟後到讀取輸入信號為止之上述一連串的控制必須在人按壓著開關的期間(例如，150ms以內)內進行。 Further, the series of controls until the input signal is read after the switch of the operation input receiving unit 18 is turned on must be performed while the person is pressing the switch (for example, within 150 ms).
其次，若停止電動吸塵器之動作，首先，藉由來自操作輸入受理部18之運轉停止信號而停止運轉。然後，開啟觸發電路17之電晶體40，並關閉主電源啟動電路15之半導體開關元件20。藉此，再次電源由2次電池12僅供給至觸發電路用電源16。其結果是，可即為縮小而抑制無負荷時之2次電池12的消耗電力。 Next, when the operation of the electric vacuum cleaner is stopped, first, the operation is stopped by the operation stop signal from the operation input receiving unit 18. Then, the transistor 40 of the flip-flop circuit 17 is turned on, and the semiconductor switching element 20 of the main power source starting circuit 15 is turned off. Thereby, the power source is again supplied from the secondary battery 12 only to the trigger circuit power source 16. As a result, the power consumption of the secondary battery 12 at the time of no load can be suppressed.
其次，以下就已連接電源線2之情況下的動作進行說明。 Next, the operation in the case where the power cord 2 is connected will be described below.
首先，電源由交流電源11供給至為主電源之電源電路13。藉此，電源電路13或微電腦19啟動。 First, the power source is supplied from the AC power source 11 to the power source circuit 13 of the main power source. Thereby, the power supply circuit 13 or the microcomputer 19 is activated.
其次，微電腦19藉由Hz信號檢測部14而判定交流頻率信號之輸入的有無。上述情況時，由於有輸入交流頻率信號，微電腦19判定為藉由交流電源11進行之電源啟動。接著，微電腦19使主電源啟動電路15之電晶體26開啟，並且開啟觸發電路17之電晶體40。 Next, the microcomputer 19 determines the presence or absence of the input of the AC frequency signal by the Hz signal detecting unit 14. In the above case, the microcomputer 19 determines that the power is turned on by the AC power source 11 because of the input of the AC frequency signal. Next, the microcomputer 19 turns on the transistor 26 of the main power source starting circuit 15 and turns on the transistor 40 of the flip-flop circuit 17.
此時，觸發電路之17之電晶體40開啟後，電流從電源線路A流通於觸發電路17之電阻42，電晶體43之基極射極間。可是，主電源啟動電路15之電晶體26已開啟。因此，電晶體21之基極射極間成為同電位。藉此，不關閉電晶體21而關閉半導體開關元件20。 At this time, after the transistor 40 of the trigger circuit 17 is turned on, current flows from the power supply line A to the resistor 42 of the flip-flop circuit 17, and between the base emitters of the transistor 43. However, the transistor 26 of the main power source starting circuit 15 is turned on. Therefore, the base emitters of the transistors 21 have the same potential. Thereby, the semiconductor switching element 20 is turned off without turning off the transistor 21.
如以上所說明，本發明之電動吸塵器包含有：吸塵器本體；把手部；及設置於前述把手部並且輸入運轉操作之操作輸入受理部，在前述吸塵器本體內至少具有：電動送風機；可連接於交流電源之電源線；2次電池；用以檢 測前述電源線有無連接於前述交流電源之Hz信號檢測部；藉由前述電動送風機之控制及前述Hz信號檢測部進行檢測之信號控制部；前述信號控制部之電源電路；從前述2次電池供給電源之觸發電路用電源；及令前述觸發電路用電源為電源之觸發電路，從前述電源線往前述電源電路之電源供給路徑，與從前述2次電池往前述電源電路之供給路徑之一部分共用，並且設置半導體開關元件作為從前述2次電池往前述電源電路之前述電源供給路徑的開閉部，當來自前述交流電源之電力供給中斷時，藉由將來自前述操作輸入受理部之前述觸發電路用電源作為電源之操作輸入之來自前述觸發電路之主電源啟動信號，前述半導體開關元件開啟，並且前述電源電路啟動而前述信號控制部開始運轉，並且在未操作輸入時僅由前述2次電池供給電源至前述觸發電路用電源。 As described above, the electric vacuum cleaner of the present invention includes: a cleaner body; a handle portion; and an operation input receiving portion provided in the handle portion and inputting an operation operation, and having at least an electric blower in the cleaner body; Power cord for power supply; 2 batteries; for inspection Detecting whether the power line is connected to the Hz signal detecting unit of the AC power source; the signal control unit that detects the electric blower and the Hz signal detecting unit; the power supply circuit of the signal control unit; and the secondary battery supply a power supply for a trigger circuit of the power supply; and a trigger circuit for causing the power supply for the trigger circuit to be a power source, and a power supply path from the power supply line to the power supply circuit is shared with a supply path from the secondary battery to the power supply circuit; Further, a semiconductor switching element is provided as an opening/closing portion of the power supply circuit from the secondary battery to the power supply circuit, and when the power supply from the AC power supply is interrupted, the trigger circuit power supply from the operation input receiving unit is provided. The main power-on signal from the trigger circuit is input as an operation input of the power source, the semiconductor switching element is turned on, and the power supply circuit is activated, and the signal control unit starts to operate, and when the input is not operated, only the secondary battery is supplied with power. The aforementioned trigger circuit uses a power source.
根據該構成，若由交流電源切換電源為2次電池，在沒有來自觸發電路之主電源啟動信號之期間內不供給電力至電源電路。藉此，在無負荷時，電源僅供給至消耗電力之極小之觸發電路用電源。其結果是，可降低2次電池之電池容量之減少。又，可抑制長期間保管造成之2次電池之過放電。其結果是，可實現信賴性優異之電動吸塵器。 According to this configuration, when the AC power supply switching power supply is the secondary battery, no power is supplied to the power supply circuit during the period when there is no main power activation signal from the trigger circuit. Thereby, when there is no load, the power supply is supplied only to the power supply for the trigger circuit which is extremely small in power consumption. As a result, the reduction in the battery capacity of the secondary battery can be reduced. Moreover, overdischarge of the secondary battery caused by storage for a long period of time can be suppressed. As a result, an electric vacuum cleaner excellent in reliability can be realized.
又，本發明之電動吸塵器亦可構成為將陶瓷電容器適用於前述觸發電路用電源之輸出平滑電容器。藉此，可縮小觸發電路用電源之漏電流。其結果是，可進而減少2次電池之電池容量的降低。 Further, the electric vacuum cleaner of the present invention may be configured to apply a ceramic capacitor to the output smoothing capacitor of the power supply for the trigger circuit. Thereby, the leakage current of the power supply for the trigger circuit can be reduced. As a result, the battery capacity of the secondary battery can be further reduced.
又，本發明之電動吸塵器亦可將齊納二極體連接於前述觸發電路用電源，而與前述2次電池串聯。藉此，若2次電池之電池電壓低時，可不啟動觸發電路用電源。因此，當2次電池之電池電壓在齊納二極體之齊納電壓以下時，停止觸發電路用電源之動作。其結果是，可更為降低2次電池之電池容量之減少，及更為延長時間直到過放電。 Further, in the electric vacuum cleaner of the present invention, the Zener diode may be connected to the power source for the trigger circuit in series with the secondary battery. Thereby, if the battery voltage of the secondary battery is low, the power supply for the trigger circuit may not be activated. Therefore, when the battery voltage of the secondary battery is below the Zener voltage of the Zener diode, the operation of the power supply for the trigger circuit is stopped. As a result, the battery capacity of the secondary battery can be further reduced, and the time can be extended until overdischarge.
