JP-A-5-18508

前記液体貯留装置は、空気清浄機、加湿機などの構造上あるいはデザイン上の問題から空気清浄機などの側面または背面のケーシングが凹んだ領域に配置され、タンクの上側にケーシングの一部が近接位置する状態となる場合がある。その場合、タンクの着脱はタンク受けに対して真上からではなくタンクを傾けた状態で斜めから行う必要があるが、特許文献１に示すような従来の液体貯留装置では、タンクを傾けた状態で受止め姿勢に設置する過程で、開閉作動する弁体の弁作動方向が弁操作部の弁押上げ方向に対して傾いた斜め状態で弁体が弁操作部に当接するために弁体に大きなストレスが加わり、このような斜め状態での着脱を繰り返した場合に、弁体が変形して適正な弁作動をしなくなる虞がある。   The liquid storage device is arranged in a region where the casing of the side or back of the air cleaner or the like is recessed due to structural or design problems of the air cleaner or humidifier, and a part of the casing is close to the upper side of the tank. It may be in a position. In that case, it is necessary to attach and detach the tank from an angle with the tank tilted, not directly above the tank receiver. However, in the conventional liquid storage device as shown in Patent Document 1, the tank is tilted. In the process of installing the valve body in the receiving posture, the valve body is in contact with the valve operating section in an oblique state in which the valve operating direction of the valve body that opens and closes is inclined with respect to the valve pushing direction of the valve operating section. When a large stress is applied and the attachment and detachment in the oblique state is repeated, the valve body may be deformed and the proper valve operation may not be performed.

本発明は、上述したような事情に鑑みてなされたものであり、タンクを受止め姿勢とは角度が異なる姿勢で着脱する場合に、弁体の弁作動方向が弁操作部の弁押上げ方向に対して斜め状態で弁体が弁操作部に当接することを抑制して適正な弁作動を確保し、弁体に大きなストレスが加わることを防止することができる液体貯留装置、及び、該液体貯留装置を備えた加湿機能付きの空気清浄機を提供することを目的とする。   The present invention has been made in view of the circumstances as described above, and when the tank is attached and detached in a posture different from the receiving posture, the valve operating direction of the valve element is the valve lifting direction of the valve operating portion. The liquid storage device that can prevent the valve body from contacting the valve operating portion in an oblique state to ensure proper valve operation and prevent a large stress from being applied to the valve body, and the liquid It aims at providing the air cleaner with a humidification function provided with the storage device.

本発明に係る液体貯留装置は、下部に形成された液出口を閉じるために下方に向けて付勢された開閉作動自在な弁体を有するタンクと、前記タンクを受け止めるタンク受けと、前記タンクが前記タンク受けに受け止められているときに前記弁体の下部に当接して前記弁体を押し上げる弁操作部と、前記弁操作部によって前記弁体が押し上げられて前記液出口が開けられているときに前記液出口から流出する液体を貯留する貯留部とを備えた液体貯留装置において、前記タンクは前記タンク受けに受け止められているときの受止め姿勢とは角度が異なる姿勢で前記タンク受けに対して着脱され、前記タンクが前記受止め姿勢にあるときに前記弁体が開閉作動する弁作動方向を、前記弁操作部が前記弁体を押し上げる弁押上げ方向に対して、前記タンク受けに着脱されるときに前記タンクがなす方向の反対側に偏倚した方向とするように構成されていることを特徴とする。   A liquid storage device according to the present invention includes a tank having a valve body that can be opened and closed and is biased downward to close a liquid outlet formed in a lower portion, a tank receiver that receives the tank, and the tank A valve operating part that pushes up the valve body in contact with the lower part of the valve body when received by the tank receiver, and the valve body is pushed up by the valve operating part to open the liquid outlet A storage part for storing the liquid flowing out from the liquid outlet, wherein the tank has an attitude different from the receiving attitude when the tank is received by the tank receiver with respect to the tank receiver. The valve operating direction in which the valve body opens and closes when the tank is in the receiving posture, and the valve operating portion pushes up the valve body with respect to the valve lifting direction. Characterized in that said tank is configured to the direction that is biased to the opposite side in the direction formed by when it is detachably attached to the receiving tank.

本発明によれば、タンクに備えた弁体の弁作動方向は、タンクが受止め姿勢のときに弁操作部が弁体を押し上げる弁押上げ方向に対して、タンク受けに着脱されるときにタンクがなす方向の反対側に偏倚しているので、タンクを受止め姿勢とは角度が異なる姿勢でタンク受けに装着する場合に、弁体の弁作動方向が弁操作部による弁押上げ方向に対して予め偏倚した偏倚分はタンクがなす方向が該偏倚の反対側であることにより打ち消されて小さくなる。その結果、弁体の弁作動方向が弁操作部の弁押上げ方向に沿う状態で弁体が弁操作部に当接して液出口を開けるように弁作動する。その後、受止め姿勢に近づくに従い、弁作動方向は弁押上げ方向に対して偏倚した状態となる。一方、タンクを受止め姿勢とは角度が異なる姿勢でタンク受けから取り出す場合は、装着時とは逆に、受止め姿勢で弁作動方向が弁押上げ方向に対して偏倚した状態で弁体が弁操作部に当接しているが、取り出し姿勢ではタンクがなす方向が該偏倚の反対側であることにより、受止め姿勢からタンクを取り出す姿勢に近づくに従い、弁作動方向が弁押上げ方向に対して偏倚した偏倚分が小さくなり、弁体の弁作動方向が弁操作部の弁押上げ方向に沿う状態で弁体が弁操作部との当接を解除して液出口を閉じるように弁作動する。   According to the present invention, the valve operating direction of the valve body provided in the tank is when the valve operating portion is attached to and detached from the tank receiver with respect to the valve pushing-up direction that pushes up the valve body when the tank is in the receiving posture. Since the tank is biased to the opposite side of the tank direction, when the tank is mounted on the tank receiver in a posture different from the receiving posture, the valve operating direction of the valve element is the direction in which the valve is pushed up by the valve operating section. On the other hand, the pre-biased deviation is canceled and reduced by the fact that the direction of the tank is on the opposite side of the deviation. As a result, the valve body operates so that the valve body abuts on the valve operating section and opens the liquid outlet in a state where the valve operating direction of the valve body is along the valve push-up direction of the valve operating section. Thereafter, as the receiving posture is approached, the valve operating direction is deviated from the valve pushing-up direction. On the other hand, when the tank is removed from the tank receiver in a posture different from the receiving posture, the valve body is in a state in which the valve operating direction is deviated from the valve push-up direction in the receiving posture, contrary to the mounting posture. Although it is in contact with the valve operating part, the direction of the tank in the take-off position is on the opposite side of the bias. The valve operates so that the valve body is released from contact with the valve operating section and the liquid outlet is closed while the valve operating direction of the valve body is along the valve push-up direction of the valve operating section. To do.

本発明に係る液体貯留装置は、下部に形成された液出口を閉じるために下方に向けて付勢された開閉作動自在な弁体を有するタンクと、前記タンクを受け止めるタンク受けと、前記タンクが前記タンク受けに受け止められているときに前記弁体の下部に当接して前記弁体を押し上げる弁操作部と、前記弁操作部によって前記弁体が押し上げられて前記液出口が開けられているときに前記液出口から流出する液体を貯留する貯留部とを備えた液体貯留装置において、前記タンクが前記タンク受けに受け止められているときの受止め姿勢とは角度が異なる着脱姿勢と前記受止め姿勢との間で姿勢変換するように案内するタンク案内部と、前記タンクが前記受止め姿勢にあるときに前記弁体が開閉作動する弁作動方向を、前記弁操作部が前記弁体を押し上げる弁押上げ方向に対して、前記着脱姿勢にあるときに前記タンクがなす方向の反対側に偏倚した方向とする状態で前記弁体を前記タンクに保持させる弁体保持部とが設けられていることを特徴とする。   A liquid storage device according to the present invention includes a tank having a valve body that can be opened and closed and is biased downward to close a liquid outlet formed in a lower portion, a tank receiver that receives the tank, and the tank A valve operating part that pushes up the valve body in contact with the lower part of the valve body when received by the tank receiver, and the valve body is pushed up by the valve operating part to open the liquid outlet In the liquid storage device comprising a storage portion for storing the liquid flowing out from the liquid outlet, the attachment / detachment posture and the receiving posture are different in angle from the receiving posture when the tank is received by the tank receiver. A tank guide portion that guides the valve body to change its posture, a valve operating direction in which the valve body opens and closes when the tank is in the receiving posture, and the valve operation portion There is provided a valve body holding portion for holding the valve body in the tank in a state of being biased to the opposite side of the direction formed by the tank when in the attach / detach posture with respect to the valve pushing-up direction. It is characterized by.

本発明によれば、タンクに備えた弁体の弁作動方向は、タンクが受止め姿勢のときに弁操作部が弁体を押し上げる弁押上げ方向に対して、タンク受けに着脱されるときにタンクがなす方向の反対側に偏倚した方向となる状態で弁体がタンクに保持されているので、タンクを受止め姿勢とは角度が異なる姿勢でタンク受けに装着するために、タンク案内部により、受止め姿勢とは角度が異なる着脱姿勢から受止め姿勢に姿勢変換するように案内する場合に、弁体の弁作動方向が弁操作部による弁押上げ方向に対して予め偏倚した偏倚分は着脱姿勢でタンクがなす方向が該偏倚の反対側であることにより小さくなる。その結果、弁体の弁作動方向が弁操作部の弁押上げ方向に沿う状態で弁体が弁操作部に当接して液出口を開けるように弁作動する。その後、受止め姿勢に姿勢変換されるに従い、弁作動方向は弁押上げ方向に対して偏倚した状態となる。一方、タンクを受止め姿勢とは角度が異なる姿勢でタンク受けから取り出すために、タンクを受止め姿勢から着脱姿勢に姿勢変換するように案内する場合は、装着時とは逆に、受止め姿勢で弁作動方向が弁押上げ方向に対して偏倚した状態で弁体が弁操作部に当接しているが、着脱姿勢でタンクがなす方向が該偏倚の反対側であることにより、受止め姿勢から着脱姿勢に姿勢変換されるに従い、弁作動方向が弁押上げ方向に対して偏倚した偏倚分が小さくなり、弁体の弁作動方向が弁操作部の弁押上げ方向に沿う状態で弁体が弁操作部との当接を解除して液出口を閉じるように弁作動する。   According to the present invention, the valve operating direction of the valve body provided in the tank is when the valve operating portion is attached to and detached from the tank receiver with respect to the valve pushing-up direction that pushes up the valve body when the tank is in the receiving posture. Since the valve body is held in the tank in a state that is biased to the opposite side of the direction that the tank makes, in order to attach the tank to the tank receiver in a posture different from the receiving posture, The deviation of the valve operating direction of the valve body in advance from the valve push-up direction by the valve operating unit when guiding to change the posture from the mounting / dismounting posture to the receiving posture is different from the receiving posture. The direction of the tank in the attach / detach posture is reduced by being on the opposite side of the bias. As a result, the valve body operates so that the valve body abuts on the valve operating section and opens the liquid outlet in a state where the valve operating direction of the valve body is along the valve push-up direction of the valve operating section. Thereafter, as the posture is changed to the receiving posture, the valve operating direction is deviated from the valve pushing-up direction. On the other hand, when the tank is guided to change its position from the receiving position to the attaching / detaching position in order to take out the tank from the tank position at a different angle from the receiving position, the receiving position is opposite to the mounting position. The valve body is in contact with the valve operating part with the valve operating direction deviated from the valve push-up direction. As the posture is changed from the detachable posture to the detachable posture, the deviation of the valve operating direction deviating from the valve lifting direction becomes smaller, and the valve body in the state where the valve operating direction of the valve body is along the valve lifting direction of the valve operating part Operates so as to release the contact with the valve operating portion and close the liquid outlet.

The engaged portion provided on the tank biasing side of the tank bottom receiving portion is engaged with the engaged portion provided on the tank biasing side that is biased in this manner, and the engagement portion between the engaged portion and the engaging portion is determined. The tank in the attach / detach posture is rotated as a fulcrum so that the posture is changed to a receiving posture that can be received by the tank receiver. When taking out the tank, guide the tank in the receiving posture to rotate to the detachable posture by rotating the tank in the opposite direction with respect to the engagement portion of the engaged portion and the engaging portion as a fulcrum, The tank in the attach / detach posture can be taken out.

本発明に係る液体貯留装置は、前述の発明において、前記タンクは、下方に突き出た筒状の液補充口と該液補充口の先端外周部にネジ結合される筒状のキャップとを備え、前記液補充口の筒軸方向は、前記タンクが前記受止め姿勢にあるときの前記弁押上げ方向に対して、前記タンク受けに着脱されるときに前記タンクがなす方向の反対側に偏倚した方向であり、前記キャップの底壁部材に、該キャップの筒軸と同心に前記液出口が設けられると共に、前記弁作動方向が前記キャップの筒軸方向と一致するように前記弁体が支持されていることを特徴とする。   In the liquid storage device according to the present invention, in the above-described invention, the tank includes a cylindrical liquid replenishing port protruding downward, and a cylindrical cap screwed to the outer peripheral portion of the tip of the liquid replenishing port, The direction of the cylinder axis of the liquid replenishing port is biased to the opposite side of the direction of the tank when the tank is attached to and detached from the direction of pushing up the valve when the tank is in the receiving posture. The liquid outlet is provided on the bottom wall member of the cap concentrically with the cylinder axis of the cap, and the valve body is supported so that the valve operating direction coincides with the cylinder axis direction of the cap. It is characterized by.

本発明によれば、タンクの下方に突き出た筒状の液補充口の筒軸方向が、タンクが受止め姿勢にあるときの前記弁押上げ方向に対して、タンク受けに着脱されるときにタンクがなす方向の反対側に偏倚した方向であるとともに、液補充口の先端外周部にネジ結合された筒状のキャップに設けられた弁体の弁作動方向がキャップの筒軸方向と一致するので、タンクをタンク受けに装着する場合及びタンクをタンク受けから取り出す場合に、弁体の弁作動方向は弁操作部による弁押上げ方向に対して同一方向に近づいた方向となる。その結果、弁体は弁操作部に対して前述のように弁作動方向が弁操作部の弁押上げ方向に沿う状態で当接し又当接を解除するように弁作動する。同時に、キャップの底壁部材に支持された弁体は、キャップの筒軸方向に沿って弁作動し、キャップの底壁部材にキャップの筒軸と同心に設けられた液出口に対して適正に開閉作動する。   According to the present invention, when the cylinder axial direction of the cylindrical liquid replenishing port protruding below the tank is attached to and detached from the tank receiver with respect to the valve pushing-up direction when the tank is in the receiving posture. The direction of the valve operation of the valve body provided on the cylindrical cap screwed to the outer periphery of the tip of the liquid replenishing port coincides with the cylinder axial direction of the cap. Therefore, when the tank is mounted on the tank receiver and when the tank is taken out from the tank receiver, the valve operating direction of the valve body is a direction approaching the same direction as the valve pushing-up direction by the valve operating portion. As a result, the valve body abuts against the valve operating portion in the state where the valve operating direction is along the valve push-up direction of the valve operating portion as described above, and operates to release the contact. At the same time, the valve body supported by the bottom wall member of the cap operates along the cylinder axis direction of the cap, and the valve body properly operates with respect to the liquid outlet provided concentrically with the cylinder axis of the cap.

貯留部１６は横壁１６ａと底部１６ｂとを有する液槽に形成されている。横壁１６ａの一部はタンク底部受け４ａの支持部を構成している。弁操作部９は柱状に形成されて上部に水平状態の当接面９ａを有し、タンク１がタンク受け４に受け止められているときに当接面９ａがタンク１の弁体７の下部に当接するように位置決めされて、貯留部１６の底部１６ｂに立設されている。ここで、弁操作部９の当接面９ａが水平状態であるので、弁操作部９の当接面９ａに垂直な方向である弁押上げ方向Ｋは鉛直方向になる。   The reservoir 16 is formed in a liquid tank having a lateral wall 16a and a bottom 16b. A part of the lateral wall 16a constitutes a support portion for the tank bottom receiver 4a. The valve operating part 9 is formed in a columnar shape and has an abutting surface 9 a in the horizontal state at the upper part. When the tank 1 is received by the tank receiver 4, the abutting surface 9 a is located at the lower part of the valve body 7 of the tank 1. It is positioned so as to abut, and is erected on the bottom 16 b of the reservoir 16. Here, since the contact surface 9a of the valve operation unit 9 is in a horizontal state, the valve push-up direction K which is a direction perpendicular to the contact surface 9a of the valve operation unit 9 is a vertical direction.

タンク１は、図１に示すように、タンク受け４に受け止められているときの姿勢（図２に示す姿勢であり、以下、受止め姿勢という）とは角度が異なる姿勢でタンク受け４に着脱される。この実施の形態では、タンク１は受止め姿勢では鉛直姿勢であり、鉛直方向から一側（タンク側部受け４ｂの反対側）に傾いた姿勢でタンク受け４に着脱される。   As shown in FIG. 1, the tank 1 is attached to and detached from the tank receiver 4 in an attitude different from the attitude when it is received by the tank receiver 4 (the attitude shown in FIG. 2, hereinafter referred to as the receiving attitude). Is done. In this embodiment, the tank 1 is in a vertical posture in the receiving posture, and is attached to and detached from the tank receiver 4 in a posture inclined from the vertical direction to one side (opposite side of the tank side portion receiver 4b).

図３は本発明に係る液体貯留装置のタンク１の全体構造を示す正面断面図であり、図４はタンク１の一部構造を拡大して示す正面断面図である。
補給用の水を入れるタンク１は、略直方体に形成され、上下方向を長手方向にした状態において、下方に突き出た筒状の液補充口３と液補充口３の先端外周部にネジ結合される筒状のキャップ２とを備えている。キャップ２の底壁部材１１に、キャップ２の筒軸と同心に液出口１０が設けられると共に、開閉作動する弁作動方向Ｊがキャップ２の筒軸方向と一致するように弁体７が支持されている。 FIG. 3 is a front sectional view showing the entire structure of the tank 1 of the liquid storage apparatus according to the present invention, and FIG. 4 is a front sectional view showing an enlarged partial structure of the tank 1.
The tank 1 for supplying water for replenishment is formed in a substantially rectangular parallelepiped, and is screwed to the cylindrical liquid replenishing port 3 protruding downward and the outer periphery of the tip of the liquid replenishing port 3 in a state where the vertical direction is the longitudinal direction. A cylindrical cap 2 is provided. The bottom wall member 11 of the cap 2 is provided with a liquid outlet 10 concentrically with the cylinder axis of the cap 2, and the valve body 7 is supported so that the valve operating direction J for opening and closing coincides with the cylinder axis direction of the cap 2. ing.

タンク１の液補充口３の筒軸方向（弁作動方向Ｊ）は、タンク１が前記受止め姿勢にあるときに弁操作部９が弁体７を押し上げる弁押上げ方向Ｋ（図２参照）に対して、タンク受け４に着脱されるときにタンク１がなす方向（図１参照）の反対側（タンク側部受け４ｂが位置する側）に偏倚量Δθで偏倚した方向とされる。ここで、偏倚量Δθは、例えば数度から１０度程度の範囲の角度（例えば４度）とする。また弁押上げ方向Ｋは受止め姿勢にあるタンク１の底部面１ａに対して垂直方向を向くように設定されているので、弁作動方向Ｊはタンク１の底部面１ａの垂直方向に対して偏倚量Δθで偏倚している。   The cylinder axial direction (valve operating direction J) of the liquid replenishing port 3 of the tank 1 is the valve pushing-up direction K in which the valve operating unit 9 pushes up the valve body 7 when the tank 1 is in the receiving posture (see FIG. 2). On the other hand, the direction is deviated by a deviation amount Δθ on the side opposite to the direction (see FIG. 1) formed by the tank 1 when being attached to and detached from the tank receiver 4 (the side on which the tank side receiver 4b is located). Here, the deviation amount Δθ is an angle (for example, 4 degrees) in a range of, for example, about several degrees to 10 degrees. Further, since the valve push-up direction K is set to be perpendicular to the bottom surface 1a of the tank 1 in the receiving posture, the valve operation direction J is relative to the vertical direction of the bottom surface 1a of the tank 1. It is biased by the bias amount Δθ.

弁体７は上下方向に伸びる棒状部７ａと、棒状部７ａの下端に形成したフランジ部７ｂと、棒状部７ａの上部側に取り付けられ、下向きの球面状（断面円弧状）に形成された弁部７ｃとからなる。フランジ部７ｂは横方向に伸びた広幅形状に形成されている。底壁部材１１はキャップ２の筒軸方向と同軸状に上方側へ延びる円筒部１１ｂを有しており、この円筒部１１ｂの上部開口が液出口１０に対応し、該上部開口縁部の内側斜面に弁座１１ｃが形成されている。円筒部１１ｂの内側の底壁部材１１の中央に貫通孔１１ａが形成され、弁体７の棒状部７ａがこの貫通孔１１ａに貫通して上下方向に沿って開閉作動自在な状態に保持されている。弁体７の下端のフランジ部７ｂと底壁部材１１の下面の間には、弁体７を液出口１０に押し付けて閉じるようにするために弁体７を下方に向けて付勢するばね１２が配置されている。弁体７の下端のフランジ部７ｂが弁操作部９の当接面９ａに当接し、弁体７が弁操作部９にて押し上げられて開状態となった液出口１０から流出した液体は、弁体７の棒状部７ａと貫通孔１１ａの間隙を通って貯留部１６に流下する。   The valve body 7 is attached to the upper side of the rod-shaped portion 7a, a rod-shaped portion 7a extending in the vertical direction, a flange portion 7b formed at the lower end of the rod-shaped portion 7a, and a valve formed in a downward spherical shape (circular arc). Part 7c. The flange part 7b is formed in the wide shape extended in the horizontal direction. The bottom wall member 11 has a cylindrical portion 11b that extends upward coaxially with the cylinder axis direction of the cap 2. The upper opening of the cylindrical portion 11b corresponds to the liquid outlet 10, and the inner side of the edge of the upper opening. A valve seat 11c is formed on the slope. A through-hole 11a is formed in the center of the bottom wall member 11 inside the cylindrical portion 11b, and the rod-like portion 7a of the valve body 7 passes through the through-hole 11a and is held in a state that can be opened and closed along the vertical direction. Yes. Between the flange 7b at the lower end of the valve body 7 and the bottom surface of the bottom wall member 11, a spring 12 that urges the valve body 7 downward to press the valve body 7 against the liquid outlet 10 and close it. Is arranged. The flange 7b at the lower end of the valve body 7 comes into contact with the contact surface 9a of the valve operating section 9, and the liquid flowing out from the liquid outlet 10 that is opened by the valve body 7 being pushed up by the valve operating section 9 is It flows down to the storage part 16 through the gap between the rod-like part 7a of the valve body 7 and the through hole 11a.

そして、液補充口３にキャップ２をネジ結合することにより、キャップ２の筒軸方向と一致するように設けた弁体７の弁作動方向Ｊが、タンク１が前記受止め姿勢にあるときに弁操作部９が弁体７を押し上げる弁押上げ方向Ｋに対して、タンク受け４に着脱されるときにタンク１がなす方向の反対側に偏倚した方向とされる。この実施の形態では、タンク１は着脱姿勢では横方向の一側（タンク側部受け４ｂの反対側）に傾くので、弁体７の弁作動方向Ｊは弁押上げ方向Ｋに対して該一側の反対側に偏倚する。また、弁体７の弁作動方向Ｊを、タンク１が受止め姿勢にあるときに弁操作部９が弁体７を押し上げる弁押上げ方向Ｋに対して、タンク受け４に着脱されるときにタンク１がなす方向の反対側に偏倚した方向とする状態で弁体７をタンク１に保持させる弁体保持部が、タンク１の液補充口３と液補充口３にネジ結合されるキャップ２とを介して、キャップ２の底壁部材１１に設けた貫通孔１１ａにて構成される。   Then, when the cap 2 is screwed to the liquid replenishing port 3 and the valve operating direction J of the valve body 7 provided so as to coincide with the cylinder axis direction of the cap 2 is when the tank 1 is in the receiving posture. The valve operating portion 9 is deviated to the opposite side of the direction formed by the tank 1 when being attached to and detached from the tank receiver 4 with respect to the valve pushing-up direction K that pushes up the valve body 7. In this embodiment, since the tank 1 is inclined to one side in the lateral direction (opposite side of the tank side receiver 4b) in the attaching / detaching posture, the valve operating direction J of the valve body 7 corresponds to the valve push-up direction K. It is biased to the opposite side. Also, when the valve operating direction J of the valve body 7 is attached to and detached from the tank receiver 4 with respect to the valve pushing-up direction K in which the valve operating portion 9 pushes up the valve body 7 when the tank 1 is in the receiving posture. A valve body holding portion for holding the valve body 7 in the tank 1 in a state of being biased in the direction opposite to the direction formed by the tank 1 is screw-coupled to the liquid replenishing port 3 and the liquid replenishing port 3 of the tank 1. And a through hole 11a provided in the bottom wall member 11 of the cap 2.

上述のタンク１の着脱動作を円滑に行うために、タンク１の底部面１ａの一端部（タンク側部受け４ｂの反対側の端部）に、タンク１の奥行方向に沿って溝状の切欠部１３が形成され、タンク底部受け４ａの受け面の一端部（タンク側部受け４ｂの反対側の端部）に、上側に突出した突出部１４がタンク１の奥行方向に沿って条の形に形成されている。タンク１を装着する場合は、図１に示すように、タンク１を横方向の一側に傾いた着脱姿勢にしてタンク１の底部面１ａの一端部をタンク底部受け４ａの受け面の一端部に載せると、タンク１の底部面１ａに設けた切欠部１３に、タンク底部受け４ａの受け面に設けた突出部１４が係合し、この係合箇所を支点として一側に傾いた着脱姿勢のタンク１が該一側の反対側に回動してタンク受け４に受け止められる受け止め姿勢（図２の状態）に姿勢変換されるように案内される。タンク１を取り出す場合は、受け止め姿勢にあるタンク１を、前記係合箇所を支点として装着時とは逆の向きに回動させて着脱姿勢に姿勢変換するように案内し、この着脱姿勢のタンク１を取り出す。   In order to smoothly perform the attaching and detaching operation of the tank 1 described above, a groove-shaped notch is formed along the depth direction of the tank 1 at one end of the bottom surface 1a of the tank 1 (the end opposite to the tank side receiver 4b). A portion 13 is formed, and at one end of the receiving surface of the tank bottom receiver 4a (the end opposite to the tank side receiver 4b), a protruding portion 14 protruding upward is shaped like a strip along the depth direction of the tank 1 Is formed. When the tank 1 is mounted, as shown in FIG. 1, the tank 1 is placed in an attaching / detaching posture inclined to one side in the horizontal direction, and one end of the bottom surface 1a of the tank 1 is set to one end of the receiving surface of the tank bottom receiver 4a. Is attached to the notch 13 provided on the bottom surface 1a of the tank 1 and the protrusion 14 provided on the receiving surface of the tank bottom receiver 4a is engaged. The tank 1 is guided so as to change its posture to a receiving posture (state shown in FIG. 2) which is rotated to the opposite side of the one side and received by the tank receiver 4. When the tank 1 is taken out, the tank 1 in the receiving posture is guided to rotate in the direction opposite to that at the time of mounting by using the engagement point as a fulcrum to change the posture to the mounting / dismounting posture. Take 1 out.

以上より、タンク１がタンク受け４に受け止められているときの受止め姿勢とは角度が異なる着脱姿勢と前記受止め姿勢との間で姿勢変換するように案内するタンク案内部が、タンク１に設けた切欠部１３とタンク底部受け４に設けた突出部１４とによって構成される。切欠部１３が、タンク１の底部面１ａの前記着脱姿勢でタンク１がなす方向が前記受止め姿勢での前記弁押上げ方向Ｋに対して偏倚するタンク偏倚側に設けられた被係合部に対応し、突出部１４が、タンク底部受け４ａの前記タンク偏倚側に設けられ、前記被係合部（切欠部１３）に係合する係合部に対応する。   As described above, the tank guide unit that guides the tank 1 so as to change the posture between the mounting posture and the mounting posture, which is different in angle from the receiving posture when the tank 1 is received by the tank receiver 4, is provided in the tank 1. The cut-out part 13 provided and the protrusion 14 provided in the tank bottom part receiver 4 are constituted. The notched portion 13 is an engaged portion provided on the tank biasing side in which the direction formed by the tank 1 in the attaching / detaching posture of the bottom surface 1a of the tank 1 is biased with respect to the valve pushing-up direction K in the receiving posture. The projecting portion 14 is provided on the tank bias side of the tank bottom receiving portion 4a and corresponds to an engaging portion that engages with the engaged portion (notch portion 13).

上述の構成の結果、タンク１が受止め姿勢にあるときに弁体７の弁作動方向Ｊが弁操作部９による弁押上げ方向Ｋに対して予め偏倚している向きと、タンク受け４に着脱されるときにタンク１が弁押上げ方向Ｋに対してなす方向の向きとが反対側であるので、タンク１を受止め姿勢とは角度が異なる姿勢でタンク受け４に装着する場合には、弁体７の弁作動方向Ｊが弁操作部９による弁押上げ方向Ｋに対して予め偏倚した偏倚分が打ち消されて小さくなり、弁作動方向Ｊが弁押上げ方向Ｋに沿う状態で弁体７が弁操作部９に当接して液出口１０を開けるように弁作動する。その後、受止め姿勢に近づくに従い、弁作動方向Ｊは弁押上げ方向Ｋに対して偏倚した状態となる。一方、タンク１を受止め姿勢とは角度が異なる姿勢でタンク受け４から取り出す場合は、装着時とは逆に、弁作動方向Ｊが弁押上げ方向Ｋに対して偏倚した状態で弁体７が弁操作部９に当接している受止め姿勢からタンク１を取り出す姿勢に近づくに従い、受止め姿勢で弁作動方向Ｊが弁押上げ方向Ｋに対して偏倚した偏倚分が小さくなり、弁体７の弁作動方向Ｊが弁操作部９の弁押上げ方向Ｋに沿う状態で弁体７が弁操作部９との当接を解除して液出口１０を閉じるように弁作動する。従って弁体７の弁作動方向Ｊが弁操作部９の弁押上げ方向Ｋに対して斜めの状態で弁体７が弁操作部９に当接することを抑制し、弁体７に大きなストレスが加わることを防止することができる。   As a result of the above-described configuration, when the tank 1 is in the receiving posture, the valve operating direction J of the valve body 7 is pre-biased with respect to the valve pushing-up direction K by the valve operating unit 9 and the tank receiver 4 When the tank 1 is attached to the tank receiver 4 in an attitude different from the receiving attitude, since the tank 1 is opposite to the direction in which the tank 1 is made with respect to the valve push-up direction K when being attached and detached. When the valve operating direction J of the valve body 7 is preliminarily deviated from the valve pushing-up direction K by the valve operating unit 9 and cancels, the valve operating direction J becomes smaller along the valve pushing-up direction K. The valve operates so that the body 7 contacts the valve operating portion 9 and opens the liquid outlet 10. Thereafter, the valve operation direction J is deviated from the valve push-up direction K as the receiving posture is approached. On the other hand, when the tank 1 is taken out from the tank receiver 4 in a posture different from the receiving posture, the valve element 7 is kept in a state in which the valve operating direction J is deviated from the valve push-up direction K, contrary to the mounting. As the tank approaches the posture of taking out the tank 1 from the receiving posture in contact with the valve operating portion 9, the deviation of the valve operating direction J from the valve pushing-up direction K in the receiving posture becomes smaller, and the valve body The valve body 7 operates so as to release the contact with the valve operating portion 9 and close the liquid outlet 10 in a state where the valve operating direction J of FIG. 7 is along the valve push-up direction K of the valve operating portion 9. Therefore, the valve element 7 is prevented from coming into contact with the valve operating part 9 when the valve operating direction J of the valve element 7 is oblique with respect to the valve pushing-up direction K of the valve operating part 9, and a large stress is applied to the valve element 7. It can be prevented from joining.

ここで、従来の液体貯留装置について説明する。図９及び図１０は従来の液体貯留装置におけるタンクの着脱状態を示す正面断面図であり、図１１は従来の液体貯留装置におけるタンクの装着状態を示す正面断面図である。
この従来の液体貯留装置では、弁体７の弁作動方向Ｊ１を、タンク１が前記受止め姿勢にあるときに弁操作部９が弁体７を押し上げる弁押上げ方向Ｋと一致する方向にしている（図１１）。このため、タンク１を受止め姿勢とは角度が異なる姿勢でタンク受け４に着脱する場合に、タンク１が受止め姿勢とは異なる角度と同じ角度、弁体７の弁作動方向Ｊ１が弁押上げ方向Ｋに対して偏倚する（図９では、左側に傾く）ので、弁体７が弁操作部９に対して斜め状態で当接し、弁体７に大きなストレスが加わる。その結果、従来の液体貯留装置では、このような斜め姿勢での着脱を繰り返した場合には、図１０に示すように、弁体７が変形して適正な弁作動をしなくなる虞があるのに対し、本発明の液体貯留装置では、前述のように、弁体７が弁操作部９に対して適正な状態で当接して弁作動し、従来の液体貯留装置のような不都合が解消される。 Here, a conventional liquid storage device will be described. FIG. 9 and FIG. 10 are front sectional views showing how the tank is attached and detached in the conventional liquid storage device, and FIG. 11 is a front sectional view showing how the tank is installed in the conventional liquid storage device.
In this conventional liquid storage device, the valve operating direction J1 of the valve body 7 is set to a direction that coincides with the valve push-up direction K in which the valve operating portion 9 pushes up the valve body 7 when the tank 1 is in the receiving posture. (FIG. 11). For this reason, when the tank 1 is attached to and detached from the tank receiver 4 in an attitude different from the receiving attitude, the same angle as the angle different from the receiving attitude of the tank 1 and the valve operating direction J1 of the valve body 7 is Since it deviates with respect to the raising direction K (inclined to the left in FIG. 9), the valve body 7 comes into contact with the valve operating portion 9 in an oblique state, and a large stress is applied to the valve body 7. As a result, in the conventional liquid storage device, when the attachment / detachment in such an oblique posture is repeated, there is a possibility that the valve body 7 is deformed and the proper valve operation is not performed as shown in FIG. On the other hand, in the liquid storage device of the present invention, as described above, the valve body 7 is brought into contact with the valve operating portion 9 in an appropriate state to operate the valve, and the inconvenience as in the conventional liquid storage device is eliminated. The

また、本発明の液体貯留装置では、図２に示すように、タンク１が受止め姿勢にあるときに弁作動方向Ｊは弁押上げ方向Ｋに対して偏倚し、弁操作部９に当接した弁体７は貫通孔１１ａの軸心に対して傾いている（この実施の形態では右側に傾く）ので、弁体７の棒状部７ａと貫通孔１１ａの間隙付近に滞留している空気層のバランスが崩れて、タンク１内の液体との置換が円滑になされ、液出口１０を通ってタンク内の液体が円滑に流出することができる。   Further, in the liquid storage device of the present invention, as shown in FIG. 2, when the tank 1 is in the receiving posture, the valve operating direction J is biased with respect to the valve pushing-up direction K and contacts the valve operating unit 9. Since the valve body 7 is inclined with respect to the axial center of the through hole 11a (in this embodiment, it is inclined to the right), the air layer staying in the vicinity of the gap between the rod-like portion 7a of the valve body 7 and the through hole 11a. Is lost, the liquid in the tank 1 is smoothly replaced, and the liquid in the tank can flow out smoothly through the liquid outlet 10.
