本出願における実施例及び実施例における特徴は、矛盾しない場合、互いに組み合わせることができることに留意されたい。以下、図面とともに実施例を参照しながら、本出願を詳細に説明する。 It should be noted that the examples and features in the examples in this application can be combined with each other where not inconsistent. The present application will now be described in detail with reference to examples in conjunction with the drawings.

図１から図１３に示すように、本実施例の切換弁は、弁座機構１０と、駆動機構２０と、スライダ３０とを含む。弁座機構１０には、収容チャンバ、並びにいずれも収容チャンバに連通される入口及び複数の出口が設置される。駆動機構２０は、弁座機構１０に接続される。スライダ３０は、収容チャンバ内に位置し、１つ又は複数の出口を回避する複数の回避位置を有するように、駆動機構２０によって弁座機構１０の軸方向に沿って移動され、即ち、この回避位置とは、複数の出口のうち一部の出口だけを回避する位置であってもよいし、全ての出口を回避する位置であってもよい。 As shown in FIGS. 1 to 13, the switching valve of this embodiment includes a valve seat mechanism 10, a drive mechanism 20, and a slider 30. As shown in FIGS. The valve seat mechanism 10 is provided with a receiving chamber and an inlet and a plurality of outlets both communicating with the receiving chamber. A drive mechanism 20 is connected to the valve seat mechanism 10 . The slider 30 is positioned within the receiving chamber and is moved along the axial direction of the valve seat mechanism 10 by the drive mechanism 20 so as to have a plurality of avoidance positions avoiding one or more exits, i.e. this avoidance The position may be a position that avoids only some of the plurality of exits, or a position that avoids all exits.

本実施例の技術方案を適用すると、切換弁のスライダ３０が弁座機構１０内で移動するときに、弁座機構１０の軸方向に沿って移動し、このように、スライダ３０の移動する空間が周方向に回動するスライダ３０の移動範囲よりも広くなることにより、切換弁の配置可能範囲が広くなり、更に切換弁への設置がより有利になる。例えば、冷蔵庫の多機能化の要求を満たすために、切換弁により多くの出口を設置することができる。本実施例の技術方案は、従来の技術における切換弁が要求を満たすことができないという課題を効果的に解決する。 When the technical solution of this embodiment is applied, when the slider 30 of the switching valve moves in the valve seat mechanism 10, it moves along the axial direction of the valve seat mechanism 10, and thus the space in which the slider 30 moves is wider than the movement range of the slider 30 rotating in the circumferential direction, the range in which the switching valve can be arranged is widened, and the installation on the switching valve becomes more advantageous. For example, more outlets can be installed in the switching valve to meet the multi-functional demands of the refrigerator. The technical solution of this embodiment effectively solves the problem that the switching valve in the prior art cannot meet the requirements.

なお、本実施例の出口は複数個であり、スライダ３０は、１つの出口を回避してもよいし、２つ、３つ、或いは４つの出口を回避してもよい等、上記の構造は切換弁の使用範囲を拡大する。スライダ３０が初期位置にあるとき、複数の出口を全て閉じてもよいし、１つ又は複数の出口を閉じてもよい。例えば、図１０におけるスライダが初期状態にあるとき、出口を全て閉じてもよく、図１１におけるスライダが初期状態にあるとき、スライダ３０は１つの出口を回避し、図１２及び図１３におけるスライダが初期状態にあるとき、スライダ３０は２つの出口を回避する。 It should be noted that the present embodiment has a plurality of outlets, and the slider 30 may avoid one outlet, or may avoid two, three, or four outlets. Expand the range of use of switching valves. When the slider 30 is in the initial position, all of the plurality of outlets may be closed, or one or more of the outlets may be closed. For example, when the slider in FIG. 10 is in its initial state, the exits may all be closed, when the slider in FIG. When in the initial state, slider 30 avoids two exits.

図１から図６に示すように、本実施例の技術方案において、弁座機構１０は、底壁及び取付口を有する側壁を有する樽状構造である弁座１１と、取付口に取り付けられ、複数の出口がいずれも設置される弁芯１２とを含む。上記の構造の設置によって、切換弁の出口を多数設置できるようになり、かつ複数の出口の配置方式は、様々な形式であってもよく、これにより冷蔵庫の使用時の多機能化を満たすことができる。例えば、図１０から図１３に示すように、弁芯の出口位置、スライダ３０の構造を設計することにより、切換弁の出口の切換を制御することができる。図１０から図１３は、１つの入口及び４つの出口の実施例であり、入口はＰ、出口はそれぞれＡ、Ｂ、Ｃ、Ｄであり、上記図面における横軸はパルス値、単位はＰＤＳであり、ケース２５の外部には電磁誘導コイルが設置されている。弁芯１２と弁座１１とは一体構造であってもよいし、別体構造であってもよい。 As shown in FIGS. 1 to 6, in the technical solution of this embodiment, the valve seat mechanism 10 includes a valve seat 11 which is a barrel-shaped structure having a bottom wall and a side wall with a mounting opening, and is attached to the mounting opening, and a valve core 12 on which the plurality of outlets are all mounted. With the installation of the above structure, it is possible to install a large number of outlets of the switching valve, and the arrangement of the outlets can be of various types, so as to satisfy the multi-functionality of the refrigerator when used. can be done. For example, as shown in FIGS. 10 to 13, by designing the outlet position of the valve core and the structure of the slider 30, the switching of the outlet of the switching valve can be controlled. 10 to 13 are examples of one inlet and four outlets, the inlet is P, the outlets are A, B, C, and D, respectively, the horizontal axis in the above drawings is the pulse value, and the unit is PDS. An electromagnetic induction coil is installed outside the case 25 . The valve core 12 and the valve seat 11 may be of an integral structure, or may be of separate structures.

図１に示すように、本実施例の技術方案において、駆動機構２０は、スライダ３０に弾性力を付与するように、スライダ３０と弁座１１の底壁との間に位置する第１の弾性部材２１と、スライダ３０の第１の弾性部材２１から離れた側に当接される駆動ロッド２２とを含む。第１の弾性部材２１と駆動ロッド２２とでスライダ３０に共に付与される力によって、スライダの移動が実現される。本実施例の技術方案において、第１の弾性部材２１はスプリングであり、説明の便宜上、図１の上下左右をスライダ３０及び弁座１１の上下左右とすると、スライダ３０の底面には、スプリングの第１の端部が位置する溝があり、弁座１１の底壁の上面には、スプリングの第２の端部が位置する溝が設置され、これによりスプリングがより安定する。駆動ロッド２２は、スライダ３０に当接されるだけであり、接続されてはいない。スライダ３０のシール面は平面であり、アーク面であってもよく、スライダ３０のシール面には、必要に応じて段差や溝等が設置されてもよく、弁芯１２の複数の出口は一列に配置されてもよく、複数列に配置されてもよく、これによりスライダ３０と弁芯１２の異なる設定によって、図１０から図１３の切換図が得られる。例えば、図４の弁芯と図８のスライダとの組み合わせによって、図１０の切換弁の切換図が得られる。具体的には、図１０から分かるように、スライダ３０が図１０の左側の第１の破線位置までスライドすると、出口Ａが開通され、このとき、スライダ３０が回避位置に位置する第１の状況となり、スライダ３０が中間破線位置まで移動すると、出口Ａ、出口Ｂ、及び出口Ｃが同時に開通され、このとき、スライダ３０が回避位置に位置する第２の状況となり、スライダ３０が図１０の右側の破線位置まで移動すると、出口Ａ、出口Ｂ、出口Ｃ、及び出口Ｄが、全部開通され、このとき、スライダ３０が回避位置に位置する第３の状況となるため、回避位置は複数個となる。 As shown in FIG. 1 , in the technical solution of this embodiment, the driving mechanism 20 is provided with a first elastic mechanism positioned between the slider 30 and the bottom wall of the valve seat 11 so as to impart elastic force to the slider 30 . It includes a member 21 and a drive rod 22 that abuts on the side of the slider 30 remote from the first elastic member 21 . Movement of the slider is achieved by the forces exerted together on the slider 30 by the first elastic member 21 and the drive rod 22 . In the technical solution of this embodiment, the first elastic member 21 is a spring. For convenience of explanation, if the top, bottom, left, and right of FIG. There is a groove in which the first end is located, and the upper surface of the bottom wall of the valve seat 11 is provided with a groove in which the second end of the spring is located, which makes the spring more stable. The drive rod 22 is only abutted against the slider 30 and is not connected. The sealing surface of the slider 30 is a flat surface, and may be an arc surface. The sealing surface of the slider 30 may be provided with steps, grooves, etc., if necessary, and the plurality of outlets of the valve core 12 are arranged in a row. 10 to 13 with different settings of the slider 30 and the valve core 12 . For example, by combining the valve core of FIG. 4 and the slider of FIG. 8, the switching diagram of the switching valve of FIG. 10 is obtained. Specifically, as can be seen from FIG. 10, when the slider 30 slides to the first dashed line position on the left side of FIG. 10, the exit A is opened, and at this time, the slider 30 is positioned at the avoidance position in the first situation. When the slider 30 moves to the middle dashed line position, the exit A, the exit B, and the exit C are opened at the same time. , the exit A, exit B, exit C, and exit D are all opened. At this time, the slider 30 is positioned at the avoidance position, which is the third situation. Become.

本実施例の技術方案において、制限孔の根元部は、制限孔及び外部空間に連通されるバランス孔を有する。制限孔が止めブロック２６の中部にある下向きの延長部内に設置されることにより、駆動ロッド２２が上下に移動する際に、制限孔内の気圧が駆動ロッド２２を制限することはない。 In the technical solution of this embodiment, the root of the restricting hole has a balancing hole communicating with the restricting hole and the outer space. Because the restriction hole is located in the downward extension in the middle of the stop block 26, the air pressure in the restriction hole does not restrict the drive rod 22 as it moves up and down.

図１に示すように、本実施例の技術方案において、止めブロック２６は、回転子２３と組み合わされる制限部を有する。回転子２３と止めブロック２６の制限部との組み合わせによって、回転子２３は、移動する位置が限界高さを超えないようになる。なお、弁座機構１０は、弁座１１の開口端に取り付けられ、かつケース２５内に位置する制限部材２７を更に含む。これにより、回転子２３が下方に移動しすぎて、限界距離を超えるのを防ぐことができる。 As shown in FIG. 1 , in the technical solution of this embodiment, the stop block 26 has a limiting part combined with the rotor 23 . The combination of the rotor 23 and the limits of the stop block 26 prevents the rotor 23 from exceeding a height limit to which it can move. The valve seat mechanism 10 further includes a restricting member 27 attached to the open end of the valve seat 11 and positioned inside the case 25 . This prevents the rotor 23 from moving too far downward and exceeding the limit distance.

図１に示すように、本実施例の技術方案において、駆動機構２０は、スライダ３０の側面に弾性的に当接される第２の弾性部材２８を更に含む。上記の構造は、切換弁の振動によるスライダ３０の位置ずれや移動等を防止することができる。なお、弁座１１の入口と弁座１１の取付口を対向して設置し、第２弾性部材２８が入口の近くに位置することにより、入口から流体が入ってきたときに、出口に向かう力をスライダ３０に付与することができ、これにより切換弁のシール効果が有利になる。 As shown in FIG. 1 , in the technical solution of this embodiment, the driving mechanism 20 further includes a second elastic member 28 elastically abutting against the side surface of the slider 30 . The above structure can prevent displacement and movement of the slider 30 due to vibration of the switching valve. The inlet of the valve seat 11 and the mounting port of the valve seat 11 are arranged to face each other, and the second elastic member 28 is positioned near the inlet. can be applied to the slider 30, which favors the sealing effect of the switching valve.

図１に示すように、本実施例の技術方案において、第２の弾性部材２８は、第１の端部がナット２４と弁座１１との間に固定され、第２の端部が自由端であり、側面がスライダの封止面とは逆の面に当接されるリードである。上記の構造は取り付けが便利で、構造がコンパクトである。 As shown in FIG. 1, in the technical solution of this embodiment, the second elastic member 28 has a first end fixed between the nut 24 and the valve seat 11 and a second end free end. , and the side surface of the lead is in contact with the surface opposite to the sealing surface of the slider. The above structure is convenient to install and compact in structure.

図４から図６に示すように、本実施例の技術方案において、一列又は複数列に配列される複数の出口は、弁芯１２に間隔を空けて設置される。上記の構造によって、切換弁の切換が比較的柔軟になる。具体的には、複数の出口の配列方式は、必要に応じて設置することができる。 As shown in FIGS. 4 to 6 , in the technical solution of this embodiment, a plurality of outlets arranged in a row or in multiple rows are installed in the valve core 12 at intervals. The above construction makes the switching of the switching valve relatively flexible. Specifically, multiple outlet arrangement schemes can be installed as required.

図７から図９に示すように、本実施例の技術方案において、スライダ３０と複数の出口との接触面は、平面又は段差面である。スライダ３０を設置した構造と弁芯１２との組み合わせによって、切換弁の切換の方式が比較的多くなり得る（具体的には、明細書の図１０から図１３を参照）。勿論、切換弁の切換方式は、図１０から図１３の切換方式に限定されない。 As shown in FIGS. 7 to 9, in the technical solution of this embodiment, the contact surface between the slider 30 and the outlets is a flat surface or a stepped surface. Depending on the combination of the structure in which the slider 30 is installed and the valve core 12, there can be a relatively large number of switching methods for the switching valve (see FIGS. 10 to 13 of the specification for details). Of course, the switching method of the switching valve is not limited to the switching methods shown in FIGS.
