Description

空気調和装置の室内機及び空気調和装置Indoor unit of air conditioner and air conditioner
　本発明は、壁の据付面に据え付けられる筐体を備える空気調和装置の室内機及び空気調和装置に関する。 The present invention relates to an indoor unit of an air conditioner and an air conditioner that include a housing that is installed on the installation surface of a wall.
　従来、壁掛け式室内機は、筐体を据付基板を介して室内の壁に設置されていた（たとえば、特許文献１参照）。 Conventionally, a wall-mounted indoor unit has a housing installed on a wall inside a room via an installation board (for example, see Patent Document 1).
特許第６１５５７３７号公報Japanese Patent No. 6155737
　ここで、室内機の筐体から室外に繋がる配管の一部が室内にて露出する場合がある。このため、室内にて露出した配管を覆うカバー部材が設けられている。 ▽Here, a part of the piping that connects the indoor unit case to the outside may be exposed indoors. Therefore, a cover member is provided to cover the pipe exposed in the room.
　一方、日本家屋には、三尺間の部屋があり、三尺間の部屋にて柱部が壁から突出している場合がある。室内機では、内部に大きい室内熱交換器が搭載される方が熱交換効率及び熱交換能力が向上できるため、筐体の左右端面間の長さが長いことが望ましい。しかし、三尺間の日本家屋に対応した室内機の場合には、三尺間の部屋にて壁から突出した柱部を回避する必要がある。このため、室内機の筐体における左右端面に、据付面との境界部を含んで柱部を回避するように凹んだ凹部が形成されている。 On the other hand, there are three shaku rooms in a Japanese house, and the pillars may protrude from the wall in the three shaku rooms. In the indoor unit, it is desirable that the length between the left and right end surfaces of the housing be long, because the heat exchange efficiency and the heat exchange capacity can be improved by mounting a large indoor heat exchanger inside. However, in the case of an indoor unit that corresponds to a Japanese house between three shaku, it is necessary to avoid the pillar portion protruding from the wall in the three shaku room. For this reason, recessed portions are formed on the left and right end surfaces of the housing of the indoor unit so as to avoid the pillar portion including the boundary portion with the installation surface.
　このような三尺間の日本家屋に対応した室内機が日本家屋の三尺間の柱部が突出しない家屋に据え付けられ、凹部側から配管を引き出し、室内に露出した配管をカバー部材で覆う場合には、カバー部材の外側断面が凹部よりも大きい。このため、現地で室内機を設置する作業者がカバー部品に複雑な加工を施す必要があった。そのため、現地での室内機の設置作業が煩雑になる課題があった。 When an indoor unit corresponding to a Japanese house of such a shaku is installed in a house where the pillars of the shaku of a Japanese house do not protrude, pull out the pipe from the recess side, and cover the pipe exposed inside the room with a cover member In addition, the outer cross section of the cover member is larger than the recess. Therefore, it is necessary for an operator who installs the indoor unit on site to perform complicated processing on the cover parts. Therefore, there is a problem that the installation work of the indoor unit on the site becomes complicated.
　本発明は、上記課題を解決するためのものであり、現地での室内機の設置作業が容易になる空気調和装置の室内機及び空気調和装置を提供することを目的とする。 The present invention is to solve the above problems, and an object of the present invention is to provide an indoor unit of an air conditioner and an air conditioner that facilitate installation work of the indoor unit on site.
　本発明に係る空気調和装置の室内機は、壁の据付面に据え付けられる筐体と、前記筐体から室外に繋がる配管と、室内にて露出した前記配管を覆うカバー部材と、前記筐体における左右端面に、前記据付面との境界部を含んで前記カバー部材の外側断面よりも広く凹んだ凹部と、を備えるものである。 An indoor unit of an air conditioner according to the present invention includes a housing that is installed on a wall installation surface, a pipe that connects the housing to the outside of the room, a cover member that covers the piping that is exposed indoors, and a housing in the housing. The left and right end surfaces are provided with recesses that are wider than the outer cross section of the cover member and include the boundary with the installation surface.
　本発明に係る空気調和装置は、上記の空気調和装置の室内機を備えるものである。 The air conditioner according to the present invention includes the indoor unit of the above air conditioner.
　本発明に係る空気調和装置の室内機及び空気調和装置によれば、筐体における左右端面に、据付面との境界部を含んでカバー部材の外側断面よりも広く凹んだ凹部を備える。これにより、日本家屋の三尺間以外の柱部が突出しない家屋に据え付け、凹部から配管を引き出し、室内に露出した配管をカバー部材で覆う場合に、凹部内にカバー部材が嵌まり込む。このため、現地で室内機を設置する作業者がカバー部品に複雑な加工を施す必要が無い。したがって、現地での室内機の設置作業が容易になる。 According to the indoor unit of the air conditioner and the air conditioner of the present invention, the left and right end surfaces of the housing are provided with recesses that are wider than the outer cross section of the cover member, including the boundary with the installation surface. As a result, the cover member fits into the recess when the pillar portion other than the shaku of the Japanese house is installed in a house where the pillar portion does not project, the pipe is pulled out from the recess, and the pipe exposed in the room is covered with the cover member. Therefore, it is not necessary for a worker who installs the indoor unit on site to perform complicated processing on the cover parts. Therefore, the installation work of the indoor unit at the site becomes easy.

<Structure of the air conditioner 100>
1 is a refrigerant circuit diagram showing an air-conditioning apparatus 100 according to Embodiment 1 of the present invention. In the air conditioner 100 shown in FIG. 1, an outdoor unit 101 and an indoor unit 102 are connected by a gas refrigerant pipe 103 and a liquid refrigerant pipe 104. The gas refrigerant pipe 103 and the liquid refrigerant pipe 104 are connected from the housing 1 of the indoor unit 102 to the outside.
　室外機１０１は、圧縮機１０５、四方弁１０６、室外熱交換器１０７及び膨張弁１０８を有する。 The outdoor unit 101 has a compressor 105, a four-way valve 106, an outdoor heat exchanger 107, and an expansion valve 108.
　圧縮機１０５は、吸入した冷媒を圧縮して吐出する。圧縮機１０５から吐出された冷媒の温度を吐出温度とする。また、圧縮機１０５の吐出配管の表面温度を吐出温度としてもよい。圧縮機１０５は、たとえばインバータ回路などにより、運転周波数を任意に変化させ、圧縮機１０５の単位時間あたりの冷媒を送り出す容量を変化させても良い。 The compressor 105 compresses the drawn refrigerant and discharges it. Let the temperature of the refrigerant discharged from the compressor 105 be the discharge temperature. Further, the surface temperature of the discharge pipe of the compressor 105 may be the discharge temperature. The compressor 105 may arbitrarily change the operating frequency by, for example, an inverter circuit or the like to change the capacity of the compressor 105 for discharging the refrigerant per unit time.
　四方弁１０６は、たとえば冷房運転時と暖房運転時とによって冷媒の流れを切り換える弁である。 The four-way valve 106 is a valve that switches the flow of refrigerant depending on, for example, a cooling operation and a heating operation.
　室外熱交換器１０７は、冷媒と室外の空気との熱交換を行う。室外熱交換器１０７は、冷房運転時に凝縮器として機能し、冷媒を凝縮して液化させる。室外熱交換器１０７は、暖房運転時に蒸発器として機能し、冷媒を蒸発させ、気化させる。 The outdoor heat exchanger 107 exchanges heat between the refrigerant and the outdoor air. The outdoor heat exchanger 107 functions as a condenser during cooling operation and condenses and liquefies the refrigerant. The outdoor heat exchanger 107 functions as an evaporator during heating operation, evaporates and vaporizes the refrigerant.
　膨張弁１０８は、流量制御弁であり、冷媒を減圧して膨張させる。膨張弁１０８は、たとえば電子式膨張弁などで構成された場合には、図示しない制御装置などの指示に基づいて開度調整を行える。 The expansion valve 108 is a flow control valve and decompresses the refrigerant to expand it. When the expansion valve 108 is composed of, for example, an electronic expansion valve, the opening degree can be adjusted based on an instruction from a control device (not shown).
　室内機１０２は、室内熱交換器１０９を有する。室内熱交換器１０９は、たとえば空調対象の空気と冷媒との熱交換を行う。室内熱交換器１０９は、冷房運転時に蒸発器として機能し、冷媒を蒸発させ、気化させる。室内熱交換器１０９は、暖房運転時に凝縮器として機能し、冷媒を凝縮して液化させる。 The indoor unit 102 has an indoor heat exchanger 109. The indoor heat exchanger 109 exchanges heat between the air to be air-conditioned and the refrigerant, for example. The indoor heat exchanger 109 functions as an evaporator at the time of cooling operation, evaporates and vaporizes the refrigerant. The indoor heat exchanger 109 functions as a condenser during heating operation and condenses and liquefies the refrigerant.
　以上のように空気調和装置１００を構成することにより、室外機１０１の四方弁１０６によって冷媒の流れを切り換え、冷房運転又は暖房運転が実現できる。 By configuring the air conditioning apparatus 100 as described above, the refrigerant flow can be switched by the four-way valve 106 of the outdoor unit 101, and cooling operation or heating operation can be realized.

FIG. 5: is a top view which shows the indoor unit 102 which removed the design panel 8 of the air conditioning apparatus 100 which concerns on Embodiment 1 of this invention.
　図４に示すように、室内機１０２は、筐体１を据付面に据え付ける据付基板４を有する。据付基板４の左右両側外縁は、凹部３の凹面３ａと面一である。 As shown in FIG. 4, the indoor unit 102 has an installation board 4 on which the housing 1 is installed on an installation surface. The left and right outer edges of the installation substrate 4 are flush with the concave surface 3 a of the concave portion 3.
　図５に示すように、筐体１における凹部３以外の左右端面間の長さは、据付基板４の左右端面間の長さよりも長い。これにより、筐体１の内部に搭載される室内熱交換器１０９の左右方向長さが長くできる。 As shown in FIG. 5, the length between the left and right end faces of the housing 1 other than the recess 3 is longer than the length between the left and right end faces of the installation board 4. As a result, the length of the indoor heat exchanger 109 mounted inside the housing 1 in the left-right direction can be increased.
＜凹部３の構成＞
　図２、図４及び図５に示すように、凹部３は、筐体１における左右端面に、据付面との境界部を含んでカバー部材２０の外側断面よりも広く凹んでいる。室内機１０２は、三尺間の日本家屋に据付自在である。そのため、凹部３は、三尺間の日本家屋における据付面から突出した柱部３０に嵌め合い自在である。据付面から突出した柱部３０を有する三尺間の日本家屋は、後述する図１２に示すような室内構成である。つまり、凹部３が筐体１における左右端面のそれぞれに形成されることにより、室内機１０２の据付面との境界部を含む据付部分の左右端面間の長さが突出した２つの柱部３０の間に収まる。 <Structure of recess 3>
As shown in FIGS. 2, 4, and 5, the recess 3 is recessed in the left and right end surfaces of the housing 1 to be wider than the outer cross section of the cover member 20 including the boundary with the installation surface.

FIG. 9 is a bottom view showing the A1 portion of FIG. 4 of the indoor unit 102 according to Embodiment 1 of the present invention in an enlarged manner when viewed from below.
　図６～図９に示すように、凹部３は、筐体１における左右端面よりも筐体１の中央側に凹み、前後及び上下の方向に平行で平坦な凹面３ａを有する。凹部３の凹面３ａは、筐体１の左右端面に対して奥行方向に平行である。凹部３は、据付基板４の左右両側外縁から凹んでいる。 As shown in FIGS. 6 to 9, the recessed portion 3 is recessed closer to the center of the housing 1 than the left and right end surfaces of the housing 1, and has a flat recessed surface 3a that is parallel to the front-back and up-down directions. The concave surface 3a of the concave portion 3 is parallel to the left and right end surfaces of the housing 1 in the depth direction. The recesses 3 are recessed from the left and right outer edges of the installation board 4.
＜三尺間対応での筐体１の拡大構造＞
　図４及び図５に示すように、筐体１の据付基板４の左右方向長さが室内機１０２の据付時の寸法である。図６に示す前後方向の寸法Ｌの凹部３を形成して三尺間対応に構成することにより、筐体１における凹部３以外の左右端面間の長さは、据付基板４の左右端面間の長さよりも長い。図５及び図７に示すように、筐体１における凹部３以外の左右端面間の長さが長いことにより、室内機１０２の内部に搭載する室内熱交換器１０９の大きさがより大きくできる。これにより、室内熱交換器１０９の熱交換性能及び熱交換能力が向上でき、空気調和装置１００の効率及び能力が向上できる。 <Enlarged structure of housing 1 for three shaku>
As shown in FIGS. 4 and 5, the length in the left-right direction of the installation board 4 of the housing 1 is the dimension when the indoor unit 102 is installed. By forming the concave portion 3 having the dimension L in the front-rear direction shown in FIG. 6 and configuring it for three shaku, the length between the left and right end surfaces of the housing 1 other than the concave portion 3 is between the left and right end surfaces of the installation substrate 4. Longer than length. As shown in FIGS. 5 and 7, since the length between the left and right end surfaces of the housing 1 other than the recessed portion 3 is long, the size of the indoor heat exchanger 109 mounted inside the indoor unit 102 can be increased. As a result, the heat exchange performance and heat exchange capacity of the indoor heat exchanger 109 can be improved, and the efficiency and capacity of the air conditioner 100 can be improved.
＜カバー部材２０の構成＞
　図１０は、本発明の実施の形態１に係る室内に露出した配管を覆うカバー部材２０を示す斜視図である。図１０に示すように、カバー部材２０は、四角筒形状である。カバー部材２０は、現地にて、室内機１０２を設置する作業者が室内に露出したガス冷媒配管１０３及び液冷媒配管１０４の長さに合わせて露出したガス冷媒配管１０３及び液冷媒配管１０４を覆う大きさに加工されて用いられる。 <Structure of cover member 20>
FIG. 10 is a perspective view showing cover member 20 that covers the pipe exposed in the room according to the first embodiment of the present invention. As shown in FIG. 10, the cover member 20 has a rectangular tube shape. The cover member 20 covers the gas refrigerant pipe 103 and the liquid refrigerant pipe 104 which are exposed to the length of the gas refrigerant pipe 103 and the liquid refrigerant pipe 104 exposed indoors by the worker who installs the indoor unit 102 on site. Used after being processed into a size.
＜凹部３とカバー部材２０との関係＞
　図１１は、本発明の実施の形態１に係る室内に露出したガス冷媒配管１０３及び液冷媒配管１０４をカバー部材２０で覆った状態の室内機１０２の図４のＡ１部を下方から見て示す下面図である。 <Relationship between the concave portion 3 and the cover member 20>
FIG. 11 shows the A1 portion of FIG. 4 of the indoor unit 102 in a state in which the gas refrigerant pipe 103 and the liquid refrigerant pipe 104 exposed in the room according to the first embodiment of the present invention are covered with the cover member 20 as seen from below. It is a bottom view.
　図１１に示すように、凹部３は、据付面との境界部を含んでカバー部材２０の前後方向の寸法Ｐである外側断面よりも広く凹んでいる。このため、寸法関係は、寸法Ｐ≦寸法Ｌの関係である。これにより、カバー部材２０は、凹部３の平坦な凹面３ａに当接する平坦な端面２０ａを有する。つまり、カバー部材２０は、現地にて、室内機１０２を設置する作業者が凹部３の平坦な凹面３ａに合わせてカバー部材２０を平坦な端面２０ａに加工される。このため、カバー部材２０には、後述する比較例のような複雑な加工が必要ない。 As shown in FIG. 11, the recessed portion 3 is recessed wider than the outer cross section that is the dimension P in the front-rear direction of the cover member 20 including the boundary with the installation surface. Therefore, the dimensional relationship is the relationship of dimension P≦dimension L. Accordingly, the cover member 20 has the flat end surface 20a that abuts the flat concave surface 3a of the concave portion 3. In other words, the cover member 20 is processed on the site by the operator who installs the indoor unit 102 to form the flat end surface 20a of the cover member 20 in accordance with the flat concave surface 3a of the concave portion 3. Therefore, the cover member 20 does not require complicated processing unlike the comparative example described later.
＜比較例の室内機１０２＞
　図１２は、比較例の室内機１０２を日本家屋の壁３１から柱部３０が突出した三尺間に据え付けた状態を示す上面図である。図１３は、比較例の室内機１０２の図１２のＡ３部を下方から見て示す説明図である。図１４は、比較例の室内に露出したガス冷媒配管１０３及び液冷媒配管１０４をカバー部材２０で覆った状態の室内機１０２の図１２のＡ３部を下方から見て示す下面図である。 <Indoor unit 102 of comparative example>
FIG. 12 is a top view showing a state in which the indoor unit 102 of the comparative example is installed between the three shakus in which the pillar portion 30 projects from the wall 31 of the Japanese house. FIG. 13 is an explanatory diagram showing the A3 portion of the indoor unit 102 of the comparative example viewed from below. FIG. 14 is a bottom view showing the A3 portion of FIG. 12 of the indoor unit 102 in a state where the gas refrigerant pipe 103 and the liquid refrigerant pipe 104 exposed in the room of the comparative example are covered with the cover member 20 from below.
　図１２に示すように、比較例の室内機１０２でも、従来の凹部２０３が三尺間の日本家屋における据付面から突出した柱部３０に嵌め合い自在である。しかし、図１３に示すように、従来の凹部２０３は、三尺間の柱部３０を回避するだけの小さな凹みであった。具体的には、従来の凹部２０３の前後方向の寸法ＯＬは、図９に示す寸法Ｌよりも短く、更には図１１に示す寸法Ｐよりも短い。つまり、これらの寸法関係は、寸法ＯＬ＜寸法Ｐ≦寸法Ｌの関係である。このため、図１４に示すように、室内に露出したガス冷媒配管１０３及び液冷媒配管１０４をカバー部材２０で覆う場合には、完全にこれらの配管が見ないようにしようとすると、カバー部材２０の加工には、従来の凹部２０３とその周囲の境界の段差に合わせた複雑な加工が必要になる。このため、比較例の室内機１０２を設置する作業者がカバー部材２０に複雑な端面加工２０ｂが必要であり、設置作業が煩雑であった。 As shown in FIG. 12, also in the indoor unit 102 of the comparative example, the conventional concave portion 203 can be freely fitted into the pillar portion 30 protruding from the installation surface in the Japanese house between the three shaku. However, as shown in FIG. 13, the conventional concave portion 203 is a small concave portion that avoids the pillar portion 30 between the three shaku. Specifically, the dimension OL of the conventional recess 203 in the front-rear direction is shorter than the dimension L shown in FIG. 9 and further shorter than the dimension P shown in FIG. That is, these dimensional relationships are such that the dimension OL<the dimension P≦the dimension L. Therefore, as shown in FIG. 14, when the gas refrigerant pipe 103 and the liquid refrigerant pipe 104 exposed in the room are covered with the cover member 20, if it is attempted to completely prevent these pipes from being seen, the cover member 20 The processing of (1) requires a complicated processing according to the step of the boundary between the conventional concave portion 203 and its periphery. Therefore, a worker who installs the indoor unit 102 of the comparative example needs a complicated end surface processing 20b on the cover member 20, and the installation work is complicated.
