Description

噴霧器Nebulizer
　本発明は、例えば園芸作業等において除草剤や消毒剤等の薬剤の噴霧（散布）等に用いられる噴霧器であって、充電により繰り返し使用できるバッテリを電源とする充電式の噴霧器に関する。 The present invention relates to a rechargeable sprayer that is used for spraying (spreading) medicines such as herbicides and disinfectants in horticultural work and the like, and uses a battery that can be repeatedly used by charging as a power source.
　この種の噴霧器に関する従来技術が特開２００５－１１８６７４号公報及び特開２００６－１５２０８号公報に開示されている。この噴霧器は、薬剤を貯留する薬剤タンクと、この薬剤タンク内の薬剤を圧送するための吐出ポンプを備えた駆動部と、駆動部から引き出されたホースの先端に取り付けられ、薬剤が実際に噴霧される噴霧ノズルを備えている。通常、薬剤タンクは駆動部に一体化されており、例えば使用者が背中に背負って噴霧作業を行う。噴霧ノズルは、使用者が手に持って噴霧作業を行う。駆動部の電源スイッチをオンすると吐出ポンプが起動して薬剤タンクから噴霧ノズルに向けて薬剤が圧送される。使用者が片手に把持した噴霧ノズルには手動操作式のノズル開閉バルブが取り付けられている。このノズル開閉バルブを開き操作すると、吐出口から薬剤が噴霧される。 Conventional techniques relating to this type of sprayer are disclosed in Japanese Patent Application Laid-Open Nos. 2005-118674 and 2006-15208. This sprayer is attached to a drug tank for storing a drug, a drive unit having a discharge pump for pumping the drug in the drug tank, and a tip of a hose drawn from the drive unit. Equipped with a spray nozzle. Usually, a medicine tank is integrated with a drive part, for example, a user carries a spraying work on the back. The spray nozzle is held in the hand of the user for spraying. When the power switch of the drive unit is turned on, the discharge pump is activated and the medicine is pumped from the medicine tank toward the spray nozzle. A manually operated nozzle opening / closing valve is attached to the spray nozzle held by one hand of the user. When the nozzle opening / closing valve is opened, the medicine is sprayed from the discharge port.
　近年、比較的大型の園芸工具である噴霧器についてもコードレス化が図られてきており、これに伴って電源としての充電式バッテリについても例えば出力電圧が３６Ｖの大型バッテリが普及してきている。 In recent years, the sprayer, which is a relatively large garden tool, has been made cordless, and as a result, for example, a large-sized battery with an output voltage of 36 V has become widespread as a rechargeable battery as a power source.
　しかしながら、例えば手持ち式の電動ねじ締め機等の電動工具用の充電式バッテリとしては、依然としてより小型の１４.４Ｖバッテリや１８Ｖバッテリが主流であり広く普及している。また、通常電動工具の使用者は予備バッテリを複数個用意して、これを作業と並行して充電しておくことにより、バッテリを取り替えながら一台の電動工具で長時間連続して作業できるようにしている。この点でも、大型の３６Ｖバッテリよりも小型の１８Ｖバッテリの方が広く普及している。 However, as rechargeable batteries for electric tools such as hand-held electric screw tighteners, smaller 14.4V batteries and 18V batteries are still mainstream and widely used. In addition, a user of a normal power tool can prepare a plurality of spare batteries and charge them in parallel with the work so that the user can work continuously for a long time with one power tool while replacing the battery. I have to. Also in this respect, a small 18V battery is more widely used than a large 36V battery.
　さらに、電動工具用のバッテリは同一電源仕様の別の電動工具間で使い回しできるようになっている。１８Ｖ仕様の電動工具の機種が豊富で広く普及していることもあって、１８Ｖバッテリの普及度は３６Ｖバッテリよりも大幅に高い。 Furthermore, the battery for the electric tool can be reused between different electric tools with the same power supply specification. Since there are many types of 18V-specific power tools widely available, 18V batteries are much more popular than 36V batteries.
　そこで、本発明は、ねじ締め機等の電動工具のバッテリとして普及している充電式のバッテリを電源として利用できるようにすることで、噴霧器の利便性及び取り扱い性を一層高めることを目的とする。 Therefore, the present invention aims to further enhance the convenience and handling of the sprayer by making it possible to use a rechargeable battery, which is widely used as a battery for power tools such as screw tighteners, as a power source. .
　本発明は、薬剤等の噴霧液を貯蔵する貯蔵タンクと、貯蔵タンク内の噴霧液を圧送する吐出ポンプと、吐出ポンプで昇圧された噴霧液を噴出するための噴霧ノズルを備えた噴霧器であって、吐出ポンプは、駆動源としての電動モータを備えており、電動モータに給電するための電源として充電可能なバッテリを複数個取り付け可能な噴霧器である。 The present invention is a sprayer including a storage tank for storing a spray liquid such as a medicine, a discharge pump for pumping the spray liquid in the storage tank, and a spray nozzle for ejecting the spray liquid pressurized by the discharge pump. The discharge pump includes an electric motor as a drive source, and is a sprayer to which a plurality of rechargeable batteries can be attached as a power source for supplying power to the electric motor.
　本発明によれば、例えば３６Ｖ電源仕様の比較的大型の噴霧器について、より低電圧出力（例えば１８Ｖ出力）のバッテリを２個電源として使用することができる。
　このことから、通常使用者がねじ締め機等の電動工具用の電源として所有するバッテリあるいはその予備バッテリとして複数個用意する等の点でより広く普及している低電圧出力のバッテリをより高電圧仕様の噴霧器の電源として用いることにより、新たな高圧バッテリを用意する必要がなくなるため、高電圧仕様の噴霧器の利便性及び取り扱い性を一層高めることができる。 According to the present invention, it is possible to use two batteries having a lower voltage output (for example, 18V output) as power supplies for a relatively large sprayer having a 36V power supply specification, for example.
For this reason, a battery with a low voltage output, which is more widely used in that a user normally owns a power source for a power tool such as a screw tightener or a plurality of spare batteries, is used. By using it as a power supply for a specified sprayer, it is not necessary to prepare a new high-voltage battery, so that the convenience and handling of a high-voltage sprayer can be further enhanced.

A changeover switch 25c and a maintenance switch 25d having a timer function for operating the discharge pump 20 for a certain period of time to circulate and wash the washing water in the storage tank 10 after the spraying operation are arranged.
　吐出ポンプ２０のポンプモータ２１は、２個のバッテリ３０，３０を電源として動作する。各実施形態では、１８Ｖ出力のリチウムイオンバッテリ（１８Ｖバッテリ）を２個直列に接続して合計電圧３６Ｖを出力する電源が構成されている。従って、ポンプモータ２１には定格３６Ｖ仕様のものが用いられている。各バッテリは、当該噴霧器１から取り外して、別途用意した充電器で充電することにより繰り返し使用することができる。また、２個のバッテリ３０，３０は、何れも電動ねじ締め機や電動切断工具等の他の電動工具の電源としても利用できるものが用いられている。従って、使用者はこれらの電動工具の電源として既に所有している複数個のバッテリをそのまま当該噴霧器１の電源としても使用することができる。 The pump motor 21 of the discharge pump 20 operates using two batteries 30 and 30 as power sources. In each embodiment, a power source is configured to connect two 18V output lithium ion batteries (18V battery) in series to output a total voltage of 36V. Accordingly, a pump motor 21 having a rating of 36V is used. Each battery can be repeatedly used by removing from the sprayer 1 and charging with a separately prepared charger. The two batteries 30 and 30 are both used as a power source for other electric tools such as an electric screw tightener and an electric cutting tool. Therefore, the user can use the plurality of batteries already owned as the power source of these electric tools as the power source of the sprayer 1 as they are.
　２個のバッテリ３０，３０は、ポンプハウジング２４の下部に設けたバッテリ収容部３１に収容されている。バッテリ収容部３１は、ポンプハウジング２４の下面側に設けられている。バッテリ収容部３１は、その前後左右をそれぞれ前壁部３１ａ、後壁部３１ｂ、左壁部３１ｃ、右壁部３１ｄで区画されて外部から遮蔽されている。また、バッテリ収容部３１の上部は天板部３１ｅによりポンプハウジング２４の内部（吐出ポンプ２０）から区画されている。また、バッテリ収容部３１の下部は底板部３１ｆにより外部から区画されている。左壁部３１ｃには、大型の開閉扉３２が設けられている。この開閉扉３２は、その上部が支軸３２ｂを介して上下に回動可能に支持されている。開閉扉３２の下部には、開閉時に使用者が指先を差し入れる取っ手部３２ａが設けられている。この開閉扉３２を上方へ開放することにより、バッテリ収容部３１内のバッテリ３０，３０を取り外すことができ、逆に取り付けることができる。 The two batteries 30 and 30 are accommodated in a battery accommodating portion 31 provided at the lower part of the pump housing 24. The battery housing portion 31 is provided on the lower surface side of the pump housing 24. The battery housing part 31 is partitioned by a front wall part 31a, a rear wall part 31b, a left wall part 31c, and a right wall part 31d on the front, rear, left and right sides thereof, and is shielded from the outside. Moreover, the upper part of the battery accommodating part 31 is divided from the inside (discharge pump 20) of the pump housing 24 by the top-plate part 31e. Moreover, the lower part of the battery accommodating part 31 is divided from the outside by the baseplate part 31f. A large opening / closing door 32 is provided on the left wall 31c. The upper portion of the open / close door 32 is supported so as to be rotatable up and down via a support shaft 32b. A handle portion 32a into which a user inserts a fingertip when opening and closing is provided at the lower portion of the open / close door 32. By opening the open / close door 32 upward, the batteries 30 and 30 in the battery housing 31 can be removed, and can be attached in reverse.
　バッテリ収容部３１の上部であって天板部３１ｅに沿ってバッテリ取り付けベース３３が設けられている。このバッテリ取り付けベース３３の下面に１８Ｖバッテリ取り付け用のバッテリ取り付け部３４，３４が前後方向に２箇所横並び（並列）状態で配置されている。両バッテリ取り付け部３４，３４のそれぞれに１つの１８Ｖバッテリ３０が取り付けられる。 A battery mounting base 33 is provided along the top plate portion 31e at the top of the battery housing portion 31. On the lower surface of the battery mounting base 33, battery mounting portions 34, 34 for mounting an 18V battery are arranged side by side (in parallel) at two locations in the front-rear direction. One 18V battery 30 is attached to each of the battery attachment portions 34, 34.
　２個のバッテリ３０，３０は、取り付けられた状態で、その側部相互間に１５ミリメートル程度の間隔があくように設定されている。２個のバッテリ３０，３０間に、指先を進入可能な程度の約１５ミリメートルの隙間があくように取り付けられることから、使用者は、当該一方のバッテリ３０の取り付け、取り外し時に他方のバッテリ３０が邪魔になることなく左右側部間を指先で挟んで保持することができ、これにより取り付け、取り外し時の操作性を高めることができる。 The two batteries 30 and 30 are set so that there is an interval of about 15 millimeters between the side portions when they are attached. Since the two batteries 30 and 30 are attached so that there is a gap of about 15 millimeters enough to allow the fingertip to enter, the user can attach the other battery 30 and remove the other battery 30 at the time of installation or removal. The left and right side portions can be sandwiched and held between the fingertips without obstruction, thereby improving the operability during attachment and removal.
　図５～図８に示すようにバッテリ３０は、概ね直方体形状のバッテリケース３０ｇ内に１０本のセル３０ｈ～３０ｈを収容したバッテリパックで、その上面には、左右一対のレール受け部３０ａ，３０ａが設けられている。両レール受け部３０ａ，３０ａ間には、正負の端子受け部３０ｂ，３０ｃが配置されている。正負の端子受け部３０ｂ，３０ｃ間には、充電器で充電する際に当該充電器との間で制御信号を送受信するためのコネクタ部３０ｄを備えている。また、バッテリ３０の上面後部には、ロック爪部３０ｅが設けられている。このロック爪部３０ｅは圧縮ばね３０ｉにより上方へ突き出す方向にばね付勢されている。このロック爪部３０ｅは、後面に設けたアンロックボタン３０ｆを指先で押し下げ操作することによりばね付勢力に抗して下方のアンロック位置に移動させることができる。 As shown in FIGS. 5 to 8, the battery 30 is a battery pack in which 10 cells 30h to 30h are accommodated in a substantially rectangular parallelepiped battery case 30g, and a pair of left and right rail receiving portions 30a and 30a are provided on the upper surface thereof. Is provided. Positive and negative terminal receiving portions 30b and 30c are arranged between the rail receiving portions 30a and 30a. Between the positive / negative terminal receiving parts 30b and 30c, when charging with a charger, a connector part 30d for transmitting and receiving a control signal to and from the charger is provided. Further, a lock claw portion 30 e is provided at the rear upper surface of the battery 30. The lock claw 30e is spring-biased in a direction protruding upward by a compression spring 30i. The lock claw portion 30e can be moved to a lower unlock position against a spring biasing force by pushing down an unlock button 30f provided on the rear surface with a fingertip.
　図９に示すように両バッテリ取り付け部３４，３４は、相互に同様の構成を備えている。このバッテリ取り付け部３４には、左右一対のレール部３４ａ，３４ａが設けられている。両レール部３４ａ，３４ａ間には、正負の接続端子３４ｂ，３４ｃが配置されている。両バッテリ取り付け部３４，３４の図示上部には、それぞれバッテリ３０のロック爪部３０ｅが嵌り込むロック係合部（係合凹部）３４ｅが設けられている。また、両バッテリ取り付け部３４，３４の図示下部には、それぞれ取り付けたバッテリ３０を取り外し方向に付勢するための付勢部材３４ｄが設けられている。本実施形態では、付勢部材３４ｄとしてリーフスプリング（板ばね）が用いられている。バッテリ３０を取り外す際にアンロックボタン３０ｆを押し下げ操作すると、当該バッテリ３０がこの付勢部材３４ｄの付勢力により取り出し方向に変位（ポップアップ）される。このため、使用者は狭いスペースであってもバッテリを確実に把持して楽に取り外すことができる。 As shown in FIG. 9, both battery mounting portions 34 and 34 have the same configuration. The battery mounting portion 34 is provided with a pair of left and right rail portions 34a and 34a. Positive and negative connection terminals 34b and 34c are disposed between the rail portions 34a and 34a. Lock engaging portions (engaging recesses) 34e into which the lock claws 30e of the battery 30 are fitted are provided on the upper portions of the battery mounting portions 34, 34 in the figure. Further, urging members 34d for urging the attached batteries 30 in the detaching direction are provided at the lower portions of the battery attachment portions 34, 34 in the figure. In the present embodiment, a leaf spring (plate spring) is used as the urging member 34d. When the unlock button 30f is pushed down when removing the battery 30, the battery 30 is displaced (popped up) in the take-out direction by the urging force of the urging member 34d. For this reason, even in a narrow space, the user can securely grasp the battery and easily remove it.
　図９に示すようにバッテリ取り付け部３４に対してバッテリ３０を図示下方へスライド（平行移動）させつつそのレール受け部３０ａ，３０ａをレール部３４ａ，３４ａに係合させることにより当該バッテリ３０をバッテリ取り付け部３４に対して機械的に結合することができる。バッテリ３０がバッテリ取り付け部３４に機械的に結合されると、同時にバッテリ取り付け部３４側の接続端子３４ｂ，３４ｃがバッテリ３０側の端子受け部３０ｂ，３０ｃに進入して電気的に接続される。また、バッテリ３０がバッテリ取り付け部３４に対して機械的に結合されると、ロック爪部３０ｅがロック係合部３４ｅ内に弾性的に嵌り込んで当該バッテリ３０がスライド方向移動不能に固定された取り付け状態にロックされる。 As shown in FIG. 9, while the battery 30 is slid downward (parallel movement) with respect to the battery mounting portion 34, the rail receiving portions 30a and 30a are engaged with the rail portions 34a and 34a, thereby making the battery 30 into the battery. It can be mechanically coupled to the attachment 34. When the battery 30 is mechanically coupled to the battery mounting portion 34, the connection terminals 34 b and 34 c on the battery mounting portion 34 side simultaneously enter the terminal receiving portions 30 b and 30 c on the battery 30 side and are electrically connected. Further, when the battery 30 is mechanically coupled to the battery mounting portion 34, the lock claw portion 30e is elastically fitted into the lock engagement portion 34e, and the battery 30 is fixed so as not to move in the sliding direction. Locked to the installed state.
　取り付けたバッテリ３０をバッテリ取り付け部３４から取り外す際には、アンロックボタン３０ｆを押し下げ操作すれば取り出し方向にポップアップされることからそのまま把持して図９において上方へ引き抜けばよい。これによりレール受け部３０ａ，３０ａがレール部３４ａ，３４ａから外れ、接続端子３４ｂ，３４ｃが端子受け部３０ｂ，３０ｃから離脱してバッテリ３０がバッテリ取り付け部３４から取り外される。 When removing the attached battery 30 from the battery attachment portion 34, if the unlock button 30f is pushed down, it pops up in the take-out direction, so that it can be gripped as it is and pulled upward in FIG. As a result, the rail receiving portions 30a and 30a are detached from the rail portions 34a and 34a, the connection terminals 34b and 34c are detached from the terminal receiving portions 30b and 30c, and the battery 30 is removed from the battery mounting portion 34.
　前記したように第１実施形態の場合は、バッテリ収納部３１の左側部に設けた開閉扉３２を開放して、２個のバッテリ３０，３０をバッテリ取り付け部３４，３４に取り付けることができ、逆に取り外すことができる。図２に示すようにバッテリ取り付け部３４，３４は、バッテリ収容部３１の内方（平面的に見て中央）に向かって下る方向に沿って配置されている。このため、２個のバッテリ３０，３０は、その上面を上側にして図２中白抜き矢印で示すように斜め下方へ向けて押し込むようにしてスライドさせることによりバッテリ取り付け部３４，３４に取り付けられ、逆に斜め上方（白抜き矢印とは逆方向）へ引き出すようにしてスライドさせることによりバッテリ取り付け部３４，３４から取り外すことができる。このように取り付け、取り外し方向を上下に傾斜させた方向とすることにより、使用者はバッテリ３０，３０のバッテリ取り付け部３４，３４に対する取り付け、取り外し操作を楽に行うことができる。 As described above, in the case of the first embodiment, the open / close door 32 provided on the left side of the battery storage unit 31 can be opened to attach the two batteries 30, 30 to the battery mounting units 34, 34. Conversely, it can be removed. As shown in FIG. 2, the battery attachment portions 34, 34 are arranged along a direction descending inward (center as viewed in plan) of the battery housing portion 31. For this reason, the two batteries 30 and 30 are attached to the battery attachment portions 34 and 34 by sliding the two batteries 30 and 30 so that the upper surface thereof is on the upper side and as shown in FIG. On the contrary, it can be removed from the battery mounting portions 34, 34 by sliding it so as to be drawn obliquely upward (in the direction opposite to the white arrow). In this way, the user can easily attach and remove the batteries 30 and 30 to and from the battery attaching portions 34 and 34 by setting the attaching and detaching directions to be inclined upward and downward.
　バッテリ３０のバッテリ取り付け部３４に対する取り付け、取り外しは、図１及び図２に示すように当該バッテリ３０の取り付け方向後面（アンロックボタン３０ｆ側）に親指をあてがい、前面にその他の指先をあてがって片手Ｈで下から受ける状態に保持して行うことができる。これにより２個のバッテリ３０，３０を迅速かつ楽に取り付け、取り外すことができる。 As shown in FIGS. 1 and 2, the battery 30 is attached to or detached from the battery attachment portion 34 by placing a thumb on the rear surface (unlock button 30 f side) in the direction of attachment of the battery 30 and placing another fingertip on the front. It can be carried out by holding in a state of receiving from below with H. Thereby, the two batteries 30 and 30 can be attached and removed quickly and easily.
　２個のバッテリ３０，３０をバッテリ収容部３１内に取り付けた状態では、当該２個のバッテリ３０，３０は比較的重量物である吐出ポンプ２０の主としてポンプモータ２１の直下に配置されている。 In a state in which the two batteries 30 and 30 are mounted in the battery housing 31, the two batteries 30 and 30 are disposed mainly directly below the pump motor 21 of the discharge pump 20 that is a relatively heavy object.
　また、図２に示すように２個のバッテリ３０，３０をバッテリ収容部３１内に取り付けた状態における当該噴霧器１の重心Ｇが、左右幅Ｗ方向について一定の領域Ｅ内に位置するようにバッテリ取り付け部３４，３４の左右幅Ｗ方向の位置が設定されている。この一定の領域Ｅは、当該噴霧器１の左右幅Ｗ方向中心の基準線Ｊを中心にして左右幅Ｗ方向それぞれ２０パーセント（０．２Ｗ）の領域に跨る範囲に設定されている。しかも、貯蔵タンク１０は基準線Ｊに対して左右対称形状を有していることから貯蔵した噴霧液の量に関係なく（満杯状態と空の状態の双方において）この重心Ｇの左右幅Ｗ方向の位置は領域Ｅ内に位置することとなる。これにより、当該噴霧器１を背中に背負った使用者は、貯蔵タンク１０内の噴霧液の量に関係なく常時左右幅Ｗ方向の重量バランスをとった状態で（左右一方に傾くことなく）背負うことができ、この点で当該噴霧器１の取り扱い性及び操作性が確保されている。 Further, as shown in FIG. 2, the battery is arranged such that the center of gravity G of the nebulizer 1 in a state where the two batteries 30, 30 are mounted in the battery housing portion 31 is located in a certain region E in the left-right width W direction. The positions of the attachment portions 34, 34 in the left-right width W direction are set. This fixed region E is set to a range that spans a region of 20 percent (0.2 W) in each of the left and right width W directions with the reference line J at the center in the left and right width W direction of the sprayer 1 as the center. In addition, since the storage tank 10 has a symmetrical shape with respect to the reference line J, the lateral width W direction of the center of gravity G regardless of the amount of sprayed liquid stored (both full and empty). Is located within the region E. As a result, the user who carries the sprayer 1 on his / her back will always carry the weight balance in the left / right width W direction (without tilting to the left or right) regardless of the amount of spray liquid in the storage tank 10. In this respect, handling and operability of the sprayer 1 are ensured.
　このように当該噴霧器１の幅方向について重心Ｇを基準線Ｊ上に位置させることが左右の重量バランスの観点から最も望ましいのであるが、現実には基準線Ｊに対して重心Ｇが左方又は右方にずれる場合があり、この場合であっても基準線Ｊから左方又は右方にそれぞれ幅Ｗの２０パーセントの範囲内に位置させることにより、実質的に左右の良好な重量バランスを確保することができる。 As described above, it is most desirable from the viewpoint of weight balance between the left and right sides to position the center of gravity G on the reference line J in the width direction of the sprayer 1. Even in this case, the left and right sides of the reference line J are positioned within 20 percent of the width W to ensure a substantially good weight balance between the left and right sides. can do.
　２個のバッテリ３０，３０の合計重量と、吐出ポンプ２０の重量と比較して、より重い方を下側に配置し、また使用者の背中側に配置することにより、使用者はより安定した姿勢で楽に背負うことができ、この点で当該噴霧器１の取り扱い性を一層高めることができる。この観点から、第１実施形態では、より重い２個のバッテリ３０，３０が吐出ポンプ２０に対して下方に取り付けられ、かつ前側（使用者の背中側）に配置された構成となっている。 Compared to the total weight of the two batteries 30 and 30 and the weight of the discharge pump 20, the heavier one is placed on the lower side, and the user is more stable by placing it on the user's back side. It can be easily carried in the posture, and the handling of the sprayer 1 can be further enhanced in this respect. From this viewpoint, in the first embodiment, two heavier batteries 30 and 30 are attached to the lower side with respect to the discharge pump 20 and are arranged on the front side (the back side of the user).
　また、前後に横並び状態に取り付けられた２個のバッテリ３０，３０間には指先を進入できる程度の約１５ミリメートルの隙間があくよう当該両バッテリ３０，３０の取り付け位置が設定されていることから、使用者はバッテリ３０の左右側部を指先で挟んで保持しつつ当該バッテリ３０を楽に取り付け、取り外しすることができる。なお、バッテリケースの容積が２００ｃｍ3以上の大形のバッテリの場合には、上記の間隔を１５ミリメートよりも小さくしてより接近した状態で複数個のバッテリを取り付ける構成とすることにより、当該複数個の大形のバッテリをバッテリ収容部内によりコンパクトに収容することができる。 In addition, the attachment positions of the batteries 30 and 30 are set so that a gap of about 15 millimeters is provided between the two batteries 30 and 30 attached side by side in front and back so that a fingertip can enter. The user can easily attach and remove the battery 30 while holding the left and right sides of the battery 30 with the fingertips. In the case of a large battery having a battery case volume of 200 cm 3 or more, the plurality of batteries can be attached in a state in which the distance is smaller than 15 mm and closer to each other. One large battery can be accommodated more compactly in the battery accommodating portion.
　以上のように構成した第１実施形態の噴霧器１によれば、定格電圧３６Ｖのポンプモータ２１を駆動源とする３６Ｖ仕様の噴霧器１を、１個の３６Ｖバッテリではなく２個の１８Ｖバッテリ３０，３０を取り付けて利用することができる。このことから、使用者は１８Ｖ仕様の電動工具用の電源として既に所有している１８Ｖバッテリ３０，３０を当該噴霧器１の電源として流用することができ、これにより当該噴霧器１の利便性及び取り扱い性を一層高めることができる。 According to the sprayer 1 of 1st Embodiment comprised as mentioned above, the 36V specification sprayer 1 which uses the pump motor 21 of the rated voltage 36V as a drive source is replaced with two 18V batteries 30 instead of one 36V battery, 30 can be attached and used. From this, the user can divert the 18V batteries 30 and 30 already owned as the power source for the 18V-specific power tool as the power source of the sprayer 1, thereby making the sprayer 1 convenient and easy to handle. Can be further enhanced.
　図１０及び図１１には、第２実施形態の噴霧器２が示されている。第２実施形態の噴霧器２は、２個のバッテリ３０，３０の取り付け位置及び取り付け方向が第１実施形態とは異なっている。その他第１実施形態と同様の部材及び構成については同位の符号を用いてその説明を省略する。 10 and 11 show the sprayer 2 of the second embodiment. The sprayer 2 of the second embodiment is different from the first embodiment in the mounting position and mounting direction of the two batteries 30 and 30. Other members and configurations similar to those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
　第２実施形態では、２個のバッテリ３０，３０は、貯蔵タンク４０と吐出ポンプ２０（ポンプハウジング２４）と間に取り付けられている。第２実施形態の貯蔵タンク４０は、その後面側下部に段付き形状の凹みが設けられている。この凹みがバッテリ収容部４１となっている。また、第２実施形態の場合、ポンプハウジング２４の上部にバッテリ取り付けベース３３を介して２箇所のバッテリ取り付け部３４，３４が設けられている。 In the second embodiment, the two batteries 30 and 30 are attached between the storage tank 40 and the discharge pump 20 (pump housing 24). The storage tank 40 according to the second embodiment is provided with a stepped recess at the lower portion on the rear surface side. This recess serves as a battery housing portion 41. In the case of the second embodiment, two battery mounting portions 34, 34 are provided on the upper portion of the pump housing 24 via the battery mounting base 33.
　バッテリ３０を下向き（レール受け部３０ａ，３０ａ側を下方に向けて）に保持して、図１０中白抜き矢印で示すようにバッテリ収容部４１の後方から内方（前方）に向けてスライドさせることにより、各バッテリ取り付け部３４に対してバッテリ３０を取り付けることができる。取り外すには、第１実施形態と同様アンロックボタン３０ｆをアンロック側（第２実施形態の場合は上側）へ押し込み操作した状態でその後部を把持して後方（図１０中白抜き矢印とは逆方向）へスライドさせればよい。取り付けたバッテリ３０とバッテリ収容部４１の上面との間には、指先を進入させるに足る隙間４３が確保されている。 The battery 30 is held downward (with the rail receiving portions 30a and 30a facing downward), and is slid from the rear of the battery accommodating portion 41 inward (forward) as indicated by the white arrow in FIG. Thus, the battery 30 can be attached to each battery attachment portion 34. To remove, as in the first embodiment, the unlock button 30f is pushed toward the unlock side (upward in the case of the second embodiment) and the rear part is gripped and rearward (the white arrow in FIG. 10 is Slide in the opposite direction). A gap 43 sufficient to allow the fingertip to enter is secured between the attached battery 30 and the upper surface of the battery housing portion 41.
　第２実施形態の場合、バッテリ３０のスライド方向は水平方向になっているが、第１実施形態よりも十分に高い部位に取り付ける構成であるので、バッテリ３０の取り付け、取り外しの際の良好な操作性が確保されている。 In the case of the second embodiment, the sliding direction of the battery 30 is horizontal, but since it is configured to be attached to a part sufficiently higher than that of the first embodiment, a good operation at the time of attaching and removing the battery 30 Is secured.
　図１１に示すようにバッテリ取り付け部３４，３４は、基準線Ｊに対して左右対称に配置されている。従って、両バッテリ３０，３０は、基準線Ｊに対して左右対称に取り付けられる。このため、噴霧器２の左右幅Ｗ方向の重心Ｇの位置についてはバッテリ３０，３０を取り付けたことが影響を及ぼすことはなく、従って第１実施形態（図２参照）と同じく領域Ｅ内に位置している。 As shown in FIG. 11, the battery mounting portions 34 and 34 are arranged symmetrically with respect to the reference line J. Accordingly, both the batteries 30 and 30 are attached symmetrically with respect to the reference line J. For this reason, the position of the center of gravity G in the left-right width W direction of the sprayer 2 does not affect the attachment of the batteries 30 and 30 and is therefore located in the region E as in the first embodiment (see FIG. 2). is doing.
　第２実施形態の場合、貯蔵タンク４０とポンプハウジング２４との間にバッテリ３０，３０が取り付けられており、第１実施形態におけるバッテリ収容部３１（前後左右の壁部３１ａ，３１ｂ，３１ｃ，３１ｄ及び底部３１ｆ）は省略されている。 In the case of 2nd Embodiment, the batteries 30 and 30 are attached between the storage tank 40 and the pump housing 24, and the battery accommodating part 31 (front and rear, right and left wall parts 31a, 31b, 31c, 31d in 1st Embodiment). And the bottom 31f) are omitted.
　以上のように構成した第２実施形態の噴霧器２によっても、第１実施形態と同様定格電圧３６Ｖのポンプモータ２１を駆動源とする３６Ｖ仕様の噴霧器２を、１個の３６Ｖバッテリではなく２個の１８Ｖバッテリ３０，３０を電源として取り付けて利用することができる。このことから、使用者は１８Ｖ仕様の電動工具用の電源として既に所有している１８Ｖバッテリ３０，３０を当該噴霧器１の電源として流用することができ、これにより当該噴霧器１の利便性及び取り扱い性を一層高めることができる。 Even with the sprayer 2 of the second embodiment configured as described above, two sprayers 2 of 36V specifications that use the pump motor 21 with a rated voltage of 36V as a drive source are used instead of one 36V battery as in the first embodiment. 18V batteries 30 and 30 can be used as power sources. From this, the user can divert the 18V batteries 30 and 30 already owned as the power source for the 18V-specific power tool as the power source of the sprayer 1, thereby making the sprayer 1 convenient and easy to handle. Can be further enhanced.
　図１２及び図１３には第３実施形態の噴霧器３が示されている。この第３実施形態も、２個のバッテリ３０，３０の取り付け位置及び取り付け方向について第１、第２実施形態とは異なっている。第１、第２実施形態と同じ部材及び構成については同位の符号を用いてその説明を省略する。 12 and 13 show the sprayer 3 of the third embodiment. This third embodiment is also different from the first and second embodiments in the mounting position and mounting direction of the two batteries 30 and 30.

For example, a configuration in which two 18V batteries 30 and 30 are attached is illustrated, but N lithium ion batteries with a rated voltage nV can be attached in series to form a power supply with an output voltage (n × N) V. (N × N) V-specific sprayer can be used.
　また、以上説明した各実施形態において、種々のバッテリ配置形態を示したが、バッテリの配置は上記例示した形態に限られるものではない。例えば、上記で示した複数のバッテリ配置箇所に、バッテリが１個ずつ配置される構成であってもよい。 In each of the embodiments described above, various battery arrangement forms are shown, but the battery arrangement is not limited to the above-exemplified form. For example, a configuration in which one battery is arranged at each of the plurality of battery arrangement locations shown above may be used.
　さらに、上記例示した各実施形態では、同一容積、同一重量のバッテリ３０を複数用いた例を示したが、異なる容積、重量のバッテリを配置するものであってもよい。特に、複数個のバッテリ３０～３０を直列的に接続する場合には、少なくとも各バッテリ３０の電圧を監視するバッテリコントローラを備えることが望ましい。 Furthermore, in each of the above-exemplified embodiments, an example in which a plurality of batteries 30 having the same volume and weight is used has been described. However, batteries having different volumes and weights may be arranged. In particular, when a plurality of batteries 30 to 30 are connected in series, it is desirable to include a battery controller that monitors at least the voltage of each battery 30.
　バッテリコントローラは、ポンプモータ２１の駆動状態を制御するモータコントローラと一体（一つのマイコンで処理を行う）であってもよいし、別体（別々のマイコンで処理を行う）であってもよいが、占有空間の減少、配線の削減などの観点から、一体であることが望ましい。バッテリコントローラＣ１の配置位置としては、配線の削減の観点からは、図２２に示すようにバッテリ取り付け部３４，３４の近傍が望ましい。 The battery controller may be integrated with the motor controller that controls the driving state of the pump motor 21 (processing is performed by one microcomputer) or may be separate (processing is performed by a separate microcomputer). From the standpoints of reducing the occupied space and reducing the wiring, it is desirable that they are integrated. The arrangement position of the battery controller C1 is preferably in the vicinity of the battery mounting portions 34 and 34 as shown in FIG. 22 from the viewpoint of reducing wiring.
　また、同様に配線の削減の観点からバッテリコントローラＣ２は、電源スイッチ２５ａ、圧力調整スイッチ２５ｂなどが配置される操作パネル２５の裏側に設置されることが望ましい。操作パネル２５は、製品の外装に配置されるため、バッテリコントローラＣ２は製品外装の内側面に沿って配置されることとなる。 Similarly, from the viewpoint of reducing wiring, the battery controller C2 is desirably installed on the back side of the operation panel 25 where the power switch 25a, the pressure adjustment switch 25b, and the like are arranged. Since the operation panel 25 is disposed on the exterior of the product, the battery controller C2 is disposed along the inner surface of the product exterior.
　さらに、発熱するバッテリコントローラを冷却するという観点からは、通常、ポンプを駆動するポンプモータのモータ軸に取付けられるファンによって発生する空気流に接するように配置されることが望ましい。すなわち、製品の外装を貫通する吸気孔から始まり、モータファンへ通じる空気通路、又は、モータファンから始まり、排気孔へ通じる空気通路、いずれかの通路の途中に配置されることが望ましい。この場合、より冷却されやすいモータの近傍に配置されることが望ましいことからも、上記操作パネル２５の裏側であってポンプモータ２１の後方に配置されることが望ましい。 Furthermore, from the viewpoint of cooling the battery controller that generates heat, it is usually desirable that the battery controller is disposed so as to be in contact with the air flow generated by the fan attached to the motor shaft of the pump motor that drives the pump. That is, it is desirable that the air passage starts from the intake hole penetrating the exterior of the product and communicates with the motor fan, or the air passage starts from the motor fan and communicates with the exhaust hole. In this case, since it is desirable to arrange in the vicinity of the motor that is more easily cooled, it is desirable to arrange it behind the operation panel 25 and behind the pump motor 21.
　また、複数個のバッテリ３０～３０を直列的に接続する場合には、いずれか１つのバッテリ３０の故障、放電によって当該噴霧器１（又は、２～７）を使用できなくなる。このため、どのバッテリ３０が放電などにより停止したかを知るために、各バッテリ３０の残容量の報知手段があることが望ましい。 In addition, when a plurality of batteries 30 to 30 are connected in series, the sprayer 1 (or 2 to 7) cannot be used due to a failure or discharge of any one of the batteries 30. For this reason, in order to know which battery 30 has stopped due to discharge or the like, it is desirable to have a means for notifying the remaining capacity of each battery 30.
　例えば２個のバッテリ３０，３０の残量表示Ｚ１，Ｚ２の表示位置としては、使用者のバッテリ取り付け時、又は、操作パネル２５の近傍に、バッテリ３０の位置に対応して表示されることが望ましい。例えば、図２３には、左側部の開閉扉３２を開放した取り付け姿勢で２個のバッテリ３０，３０が前後（使用者から見て左右）に位置して見える場合には、各バッテリ３０の残量表示Ｚ１，Ｚ２もバッテリ取り付けベース３３の左側部に、あるいは操作パネル２５の上側に左右に並ぶように表示されることが望ましい。残量表示Ｚ１，Ｚ２は、表示ボタンＺｂの押し操作により点灯表示する。 For example, the display positions of the remaining amount indications Z1 and Z2 of the two batteries 30 and 30 may be displayed corresponding to the position of the battery 30 when the user installs the battery or in the vicinity of the operation panel 25. desirable. For example, in FIG. 23, when the two batteries 30, 30 appear to be positioned front and rear (left and right as viewed from the user) with the left open / close door 32 opened, the remaining battery 30 is left. It is desirable that the quantity indications Z1 and Z2 are also displayed on the left side of the battery mounting base 33 or on the upper side of the operation panel 25 so as to be arranged side by side. The remaining amount displays Z1 and Z2 are turned on by pressing the display button Zb.
　また、使用者への報知の方法も、上記の残量表示Ｚ１，Ｚ２のように複数のバーで残容量を示すものに限られず、色、点滅速度、音などで行ってもよい。
　なお、バッテリが所定値を下回る残容量となった場合（駆動停止状態の場合）に、どのバッテリが原因かを示す機能（ランプの点滅、赤色表示）を備えていてもよい。 Further, the method of notifying the user is not limited to the method of indicating the remaining capacity with a plurality of bars as in the remaining amount indications Z1 and Z2, but may be performed by color, blinking speed, sound, or the like.
In addition, when the remaining capacity of the battery becomes lower than a predetermined value (when the drive is stopped), a function indicating which battery is the cause (blinking of the lamp, red display) may be provided.
　また、上記した各実施形態では、複数個のバッテリを噴霧器本体に設けた複数箇所のバッテリ取り付け部に直接取り付ける構成を例示したが、１箇所のバッテリ取り付け部を有する噴霧器本体に、例えば２つのバッテリを取り付けたバッテリコンバータを取り付けて当該２つのバッテリを電源とする構成としてもよい。 Further, in each of the above-described embodiments, the configuration in which a plurality of batteries are directly attached to a plurality of battery attachment portions provided in the sprayer body is illustrated. However, for example, two batteries are attached to the sprayer body having one battery attachment portion. It is good also as a structure which attaches the battery converter which attached and uses the said two batteries as a power supply.
