（実施形態）
図１は冷蔵庫１００の外観を示す図、図２は冷蔵庫１００の縦断面を示す図である。冷蔵庫１００は、金属製（例えば鉄板）の外箱と、硬質樹脂製（例えばＡＢＳ）の内箱と、外箱と内箱との間に充填した発泡断熱材（例えば硬質ウレタン）とで構成される。冷蔵庫１００は、冷蔵室２００、切替室２０１、製氷室２０２、冷凍室２０３、野菜室２０４とで構成される複数の貯蔵室を備える。図１の扉１０１、１０２、１０３、１０４、１０５は、それぞれ冷蔵室２００、切替室２０１、製氷室２０２、冷凍室２０３、野菜室２０４を開閉するための扉である。 Hereinafter, embodiments of the present invention will be described using the drawings. The following embodiments do not limit the invention according to the claims, and all combinations of the features described in the embodiments are not necessarily essential to the solution means of the invention.
(Embodiment)
FIG. 1 is a view showing the appearance of the refrigerator 100, and FIG. 2 is a view showing a longitudinal cross section of the refrigerator 100. As shown in FIG. The refrigerator 100 is composed of an outer case made of metal (e.g. iron plate), an inner case made of hard resin (e.g. ABS), and a foam insulation (e.g. hard urethane) filled between the outer case and the inner case Ru. The refrigerator 100 is provided with a plurality of storage rooms including a refrigerating room 200, a switching room 201, an ice making room 202, a freezing room 203, and a vegetable room 204. Doors 101, 102, 103, 104, and 105 in FIG. 1 are doors for opening and closing the cold storage room 200, the switching room 201, the ice making room 202, the freezing room 203, and the vegetable room 204, respectively.

冷蔵室２００は、冷蔵保存のために、保存物が凍らない冷蔵温度帯に設定されている。野菜室２０４は、野菜の保存に適した温度として、冷蔵室２００よりやや高い温度帯に設定されている。冷凍室２０３は、冷凍保存のために、冷凍温度帯に設定されている。切替室２０１の温度帯は、複数の温度帯の中からユーザが所望の温度帯に切り替えることができる。   The refrigerator compartment 200 is set to a refrigeration temperature zone where stored items do not freeze for refrigeration storage. The vegetable compartment 204 is set at a temperature slightly higher than that of the refrigerator compartment 200 as a temperature suitable for storing vegetables. The freezer compartment 203 is set in a freezer temperature zone for the purpose of refrigeration storage. The temperature zone of the switching chamber 201 can be switched to a desired temperature zone by the user from among a plurality of temperature zones.

また、冷蔵庫１００は、冷蔵庫１００の上部に位置する第１の機械室２０５、冷蔵庫１００の下部に位置する第２の機械室２０７、冷蔵庫１００の背面に位置する冷却室２０８を備える。冷却室２０８には、冷気を生成する冷却器２０９や、冷却器２０９に付着した霜を除去するための除霜ヒータ等が収容されている。第１の機械室２０５には、圧縮機２０６等が収用されている。第２の機械室２０７には、後述する三方弁３０１、除霜皿４０１、除霜ファン４０２等が収容されている。   In addition, the refrigerator 100 includes a first machine room 205 located in the upper part of the refrigerator 100, a second machine room 207 located in the lower part of the refrigerator 100, and a cooling room 208 located in the back of the refrigerator 100. In the cooling chamber 208, a cooler 209 that generates cool air, a defrost heater for removing frost attached to the cooler 209, and the like are accommodated. The compressor 206 and the like are accommodated in the first machine room 205. In the second machine room 207, a three-way valve 301, a defrosting tray 401, a defrosting fan 402 and the like which will be described later are accommodated.

次に図３を用いて、冷蔵庫１００が備える冷凍サイクルについて説明する。冷蔵庫１００が備える冷凍サイクルは、圧縮機２０６と、コンデンサ３０２と、放熱パイプ３０３、３０４、３０５と、キャピラリーチューブ３０８、３０９、３１１と、冷却器２０９と、サクションパイプ３１２とで構成される。冷蔵庫１００は、この冷凍サイクルに冷媒を封入して冷却運転を行う。   Next, the refrigeration cycle provided in the refrigerator 100 will be described using FIG. 3. The refrigeration cycle included in the refrigerator 100 includes a compressor 206, a condenser 302, heat radiation pipes 303, 304, 305, capillary tubes 308, 309, 311, a cooler 209, and a suction pipe 312. The refrigerator 100 performs a cooling operation by sealing a refrigerant in the refrigeration cycle.

放熱パイプ３０３は、三方弁３０１を介して放熱パイプ３０４と放熱パイプ３０５とに分岐する。放熱パイプ３０４は冷蔵庫１００の前面に設けられていて、放熱パイプ３０５は冷蔵庫１００の背面又は側面に設けられている。冷蔵庫１００には、外気の温度や湿度を検知するセンサが設けられている。冷蔵庫１００は、これらのセンサの検出結果に基づいて、冷蔵庫１００の正面開口部に結露が発生しやすい状態であるか否かを判定する。通常、冷媒は放熱パイプ３０５を流れているが、結露が発生しやすい状態であると判定されると、三方弁３０１は、放熱パイプ３０４に冷媒が流れるように、冷媒の流路を切り替える。放熱パイプ３０４に冷媒を流すことで、冷蔵庫１００の正面開口部に結露が発生することを防止できる。三方弁３０１は、複数の冷媒配管（本実施形態では放熱パイプ３０４と放熱パイプ３０５）の中から、冷媒を流す冷媒配管を選択する調節部材の一例である。   The heat release pipe 303 branches into the heat release pipe 304 and the heat release pipe 305 via the three-way valve 301. The heat radiation pipe 304 is provided on the front of the refrigerator 100, and the heat radiation pipe 305 is provided on the back or side of the refrigerator 100. The refrigerator 100 is provided with a sensor that detects the temperature and humidity of the outside air. The refrigerator 100 determines whether condensation is likely to occur at the front opening of the refrigerator 100 based on the detection results of these sensors. Normally, the refrigerant flows through the heat release pipe 305, but when it is determined that condensation is likely to occur, the three-way valve 301 switches the flow path of the refrigerant so that the refrigerant flows through the heat release pipe 304. By flowing the refrigerant through the heat release pipe 304, it is possible to prevent the occurrence of condensation at the front opening of the refrigerator 100. The three-way valve 301 is an example of a control member that selects a refrigerant pipe in which the refrigerant flows from the plurality of refrigerant pipes (in the present embodiment, the heat release pipe 304 and the heat release pipe 305).

放熱パイプ３０４は、ストレーナ３０６を介してキャピラリーチューブ３０８に接続する。また、放熱パイプ３０５は、ストレーナ３０７を介してキャピラリーチューブ３０９に接続する。キャピラリーチューブ３０８とキャピラリーチューブ３０９は、ジョイント機構３１０に接続する。ジョイント機構３１０の出口部にはキャピラリーチューブ３１１が接続されていて、ジョイント機構３１０によって二つの冷媒の流路が一つの流路に合流する。キャピラリーチューブ３１１は冷却器２０９に接続し、冷却器２０９を出た冷媒はサクションパイプ３１２を介して圧縮機２０６に戻る。   The heat radiation pipe 304 is connected to the capillary tube 308 via a strainer 306. Also, the heat radiation pipe 305 is connected to the capillary tube 309 via the strainer 307. The capillary tube 308 and the capillary tube 309 are connected to the joint mechanism 310. The capillary tube 311 is connected to the outlet portion of the joint mechanism 310, and the joint mechanism 310 joins the two refrigerant flow paths into one flow path. The capillary tube 311 is connected to the cooler 209, and the refrigerant leaving the cooler 209 returns to the compressor 206 via the suction pipe 312.

次に図４を用いて、第２の機械室２０７を説明する。第２の機械室２０７には、冷媒の流れを調節する三方弁３０１、除霜ヒータの除霜によって発生した除霜水を貯める除霜皿４０１、除霜皿に溜まった除霜水を蒸発させるための除霜ファン４０２等が収容されている。   Next, the second machine room 207 will be described with reference to FIG. In the second machine room 207, a three-way valve 301 for adjusting the flow of refrigerant, a defrost plate 401 for storing defrost water generated by defrosting of the defrost heater, and evaporation of defrost water accumulated in the defrost plate A defrost fan 402 and the like are housed.

次に図５を用いて、三方弁３０１を詳しく説明する。三方弁３０１は、取付部材５０１によって冷蔵庫１００（本実施形態では第２の機械室２０７の壁面）に取り付けられている。冷媒配管５０２は放熱パイプ３０３の一部であり、冷媒が冷媒配管５０２から三方弁３０１に流入する。冷媒配管５０３は放熱パイプ３０４の一部であり、また、冷媒配管５０４は放熱パイプ３０５の一部である。三方弁３０１は、冷媒配管５０３と冷媒配管５０４の中から、冷媒を流す冷媒配管を選択する。具体的に説明すると、通常の状態では、三方弁３０１は、冷媒を流す冷媒配管として冷媒配管５０４を選択する。一方、冷蔵庫１００の正面開口部に結露が発生しやすい状態であれば、三方弁３０１は、冷媒を流す冷媒配管として冷媒配管５０３を選択する。   Next, the three-way valve 301 will be described in detail with reference to FIG. The three-way valve 301 is attached to the refrigerator 100 (in the present embodiment, a wall surface of the second machine room 207) by an attachment member 501. The refrigerant pipe 502 is a part of the heat radiation pipe 303, and the refrigerant flows from the refrigerant pipe 502 into the three-way valve 301. The refrigerant pipe 503 is a part of the heat release pipe 304, and the refrigerant pipe 504 is a part of the heat release pipe 305. The three-way valve 301 selects a refrigerant pipe in which the refrigerant flows from the refrigerant pipe 503 and the refrigerant pipe 504. Specifically, in the normal state, the three-way valve 301 selects the refrigerant pipe 504 as a refrigerant pipe through which the refrigerant flows. On the other hand, if condensation is apt to occur at the front opening of the refrigerator 100, the three-way valve 301 selects the refrigerant pipe 503 as a refrigerant pipe through which the refrigerant flows.

次に図６を用いて、取付部材５０１と三方弁３０１の構造を詳しく説明する。取付部材５０１は、第１の面６０１、第２の面６０２、接続部６０３とで構成される。第１の面６０１には、三方弁３０１が取り付けられる。三方弁３０１は、ゴム材料で形成される弾性部材６０５を介した状態で、ネジ６０６によって第１の面６０１に取り付けられている。弾性部材６０５によって、後述する三方弁３０１の振動が第１の面６０１に伝わりにくくなる。また、第２の面６０２の上方には、取付機構６０４（例えばネジ穴）が設けられていている。この取付機構６０４によって、第２の面６０２が冷蔵庫１００（本実施形態では第２の機械室２０７の壁面）に取り付けられる。また、第１の面６０１と第２の面６０２とを繋げる接続部６０３は、Ｕ字形状である。接続部６０３をＵ字形状にすることで、後述する三方弁３０１の振動が冷蔵庫１００に伝わりにくくなる。   Next, the structure of the attachment member 501 and the three-way valve 301 will be described in detail with reference to FIG. The mounting member 501 is composed of a first surface 601, a second surface 602, and a connection portion 603. A three-way valve 301 is attached to the first surface 601. The three-way valve 301 is attached to the first surface 601 by a screw 606 with an elastic member 605 formed of a rubber material. The elastic member 605 makes it difficult for the vibration of the three-way valve 301 described later to be transmitted to the first surface 601. Further, an attachment mechanism 604 (for example, a screw hole) is provided above the second surface 602. The second surface 602 is attached to the refrigerator 100 (in the present embodiment, a wall surface of the second machine room 207) by the attachment mechanism 604. Further, the connection portion 603 connecting the first surface 601 and the second surface 602 is U-shaped. By making the connection portion 603 U-shaped, it is difficult for the vibration of the three-way valve 301 to be described later to be transmitted to the refrigerator 100.

三方弁３０１はモータ駆動のため、例えば冷媒の流路を切り替える動作を三方弁３０１が行う際に、振動が発生する。本実施形態では、第１の面６０１が第２の面６０２に対して略直交する向きであるため、第１の面６０１と第２の面６０２がそれぞれ異なる向きに撓むことになる。即ち、第１の面６０１と第２の面６０２が、三方弁３０１から生じる水平方向の振動と垂直方向の振動の両方を吸収することになり、三方弁３０１の振動が冷蔵庫１００に伝わりにくくなる。また、第２の面６０２の取付機構６０４は三方弁３０１よりも上方に設けられているため、第２の面６０２は、三方弁３０１から生じる振動をより多く吸収できる。   Since the three-way valve 301 is driven by a motor, vibration occurs, for example, when the three-way valve 301 performs an operation of switching the flow path of the refrigerant. In the present embodiment, since the first surface 601 is in a direction substantially orthogonal to the second surface 602, the first surface 601 and the second surface 602 are bent in different directions. That is, the first surface 601 and the second surface 602 absorb both the horizontal vibration and the vertical vibration generated from the three-way valve 301, and the vibration of the three-way valve 301 is less likely to be transmitted to the refrigerator 100. . In addition, since the attachment mechanism 604 of the second surface 602 is provided above the three-way valve 301, the second surface 602 can absorb more vibration generated from the three-way valve 301.

また、接続部６０３をＵ字形状にすることで、接続部６０３を設けずに第１の面６０１を第２の面６０２に直接繋げる場合に比べて、三方弁３０１から取付機構６０４までの距離を長くできる。三方弁３０１から取付機構６０４までの距離を長くすることで、三方弁３０１の振動が冷蔵庫１００に伝わりにくくなる。   Further, by forming the connection portion 603 in a U shape, the distance from the three-way valve 301 to the attachment mechanism 604 is higher than when the first surface 601 is directly connected to the second surface 602 without providing the connection portion 603. Can be lengthened. By lengthening the distance from the three-way valve 301 to the attachment mechanism 604, the vibration of the three-way valve 301 is less likely to be transmitted to the refrigerator 100.

三方弁３０１の下部に接続している冷媒配管６０８と、冷媒配管６０８に接続している冷媒配管６０７は、図５の冷媒配管５０２に対応する。また、三方弁３０１の下部に接続している冷媒配管６１０と、冷媒配管６１０に接続している冷媒配管６０９は、図５の冷媒配管５０３に対応する。また、三方弁３０１の下部に接続している冷媒配管６１２と、冷媒配管６１２に接続している冷媒配管６１１は、図５の冷媒配管５０４に対応する。冷媒配管６０７と冷媒配管６０９と冷媒配管６１１は、それぞれ異なる方向に曲がる形状である。具体的に説明すると、冷媒配管６０７は、冷蔵庫１００の正面から見て左右方向に曲がっている。また、冷媒配管６０９は、冷蔵庫１００の正面から見て斜め方向に曲がっている。また、冷媒配管６１１は、冷蔵庫１００の正面から見て前後方向に曲がっている。冷媒配管６０７と冷媒配管６０９と冷媒配管６１１がそれぞれ異なる方向に曲がっていることで、様々な向きの三方弁３０１の振動が冷媒配管に吸収され、三方弁３０１の振動が冷媒配管を介して冷蔵庫１００に伝わりにくくなる。   A refrigerant pipe 608 connected to the lower part of the three-way valve 301 and a refrigerant pipe 607 connected to the refrigerant pipe 608 correspond to the refrigerant pipe 502 in FIG. 5. A refrigerant pipe 610 connected to the lower part of the three-way valve 301 and a refrigerant pipe 609 connected to the refrigerant pipe 610 correspond to the refrigerant pipe 503 in FIG. 5. A refrigerant pipe 612 connected to the lower part of the three-way valve 301 and a refrigerant pipe 611 connected to the refrigerant pipe 612 correspond to the refrigerant pipe 504 in FIG. 5. The refrigerant pipe 607, the refrigerant pipe 609, and the refrigerant pipe 611 are curved in different directions. Specifically, the refrigerant pipe 607 is bent in the left-right direction when viewed from the front of the refrigerator 100. Further, the refrigerant pipe 609 is bent in an oblique direction when viewed from the front of the refrigerator 100. Further, the refrigerant pipe 611 is curved in the front-rear direction as viewed from the front of the refrigerator 100. The refrigerant pipe 607, the refrigerant pipe 609, and the refrigerant pipe 611 are bent in different directions, so that the vibration of the three-way valve 301 in various directions is absorbed by the refrigerant pipe, and the vibration of the three-way valve 301 is refrigerator via the refrigerant pipe. It will be difficult to reach 100.

以上の説明の通り、第１の面６０１を第２の面６０２に対して略直交する向きにし、かつ、第１の面６０１と第２の面６０２とを繋げる接続部６０３をＵ字形状にすることで、三方弁３０１の振動が冷蔵庫１００に伝わることを抑制できる。また、三方弁３０１の振動が冷蔵庫１００に伝わることを抑制することで、三方弁３０１の振動が冷蔵庫１００に伝わることで発生する音を低減することができる。   As described above, the first surface 601 is oriented substantially orthogonal to the second surface 602, and the connection portion 603 connecting the first surface 601 and the second surface 602 is formed in a U shape. By doing this, transmission of the vibration of the three-way valve 301 to the refrigerator 100 can be suppressed. Further, by suppressing the transmission of the vibration of the three-way valve 301 to the refrigerator 100, it is possible to reduce the sound generated by the transmission of the vibration of the three-way valve 301 to the refrigerator 100.

なお、本実施形態の取付部材５０１は金属製であることを想定しているが、樹脂等の他の材料で取付部材５０１を実現しても良い。また、三方弁３０１に限らず、他の種類の調節部材、例えば冷媒の流量を調節する調節部材を冷蔵庫１００に取り付ける際に、取付部材５０１を用いても良い。また、三方弁３０１のような調節部材を冷蔵庫１００に取り付ける場所も、第２の機械室２０７に限らず、第１の機械室２０５や、冷蔵室２００等の貯蔵室の内部であっても良い。   In addition, although the attachment member 501 of this embodiment assumes that it is metal, the attachment member 501 may be implement | achieved with other materials, such as resin. In addition to the three-way valve 301, the attachment member 501 may be used when another type of adjustment member, for example, an adjustment member for adjusting the flow rate of the refrigerant is attached to the refrigerator 100. Also, the place where the adjustment member such as the three-way valve 301 is attached to the refrigerator 100 may be inside the storage room such as the first machine room 205 or the refrigerating room 200 instead of the second machine room 207. .

本発明は、家庭用の冷蔵庫や冷凍庫、業務用の冷蔵庫や冷凍庫に適用できる。   The present invention can be applied to household refrigerators and freezers and commercial refrigerators and freezers.
