Form.
　図１０は、実施の形態に係る空気調和機１０３の室内機１０１に設けられた表示光カバー１の斜視図である。図１１は、実施の形態に係る空気調和機１０３の室内機１０１に設けられた表示光カバー１に形成された運転状態表示を示す図である。 FIG. 10 is a perspective view of the display light cover 1 provided in the indoor unit 101 of the air conditioner 103 according to the embodiment. FIG. 11 is a diagram showing an operating state display formed on the display light cover 1 provided in the indoor unit 101 of the air conditioner 103 according to the embodiment.
　表示光カバー１は、射出成形により成形される。表示光カバー１の表示部品Ａ側のＬＥＤ表示部分２の裏面３及び表面４には、ＬＥＤ光源部品１０に取り付けられたＬＥＤ基板のＬＥＤから発光した光に対応する室内機１０１の運転状態を示す形状が形成される。表面４（図５参照）に形成される形状及び裏面３（図５参照）に形成される形状は同一であり、凹形状で形成される。 The display light cover 1 is molded by injection molding. The back surface 3 and the front surface 4 of the LED display portion 2 on the display component A side of the display light cover 1 show the operating state of the indoor unit 101 corresponding to the light emitted from the LED of the LED substrate attached to the LED light source component 10. The shape is formed. The shape formed on the front surface 4 (see FIG. 5) and the shape formed on the back surface 3 (see FIG. 5) are the same, and are formed in a concave shape.
　実施の形態の表示光カバー１の板厚は、基本的に２ｍｍ程度で形成される。図１１において、表示光カバー１のＬＥＤ表示部分２に形成された運転状態表示のうち、部分２０の板厚は１ｍｍ程度、部分３０の板厚は２ｍｍ程度である。部分２０は、板厚が薄いので、表示光カバー１に照射されたＬＥＤ光１１が透過しやすく、ＬＥＤ光１１が外部からはっきり認識される。部分３０は、部分２０に比べて板厚が厚いので、表示光カバー１に照射されたＬＥＤ光１１が透過しにくく、ＬＥＤ光１１はぼんやりと見える。表示光カバー１を通過したＬＥＤ光１１によって表示光カバー１の部分２０に形成された形状を使用者に認識させるためには、部分２０の板厚を、表示光カバー１の板厚に対して半分の１ｍｍ程度の板厚にすることが望ましい。表示光カバー１のＬＥＤ表示部分２に運転状態を示す形状を、形状幅が１ｍｍ程度以下で作成する場合、射出成形機に細長い金型形状が必要となる。射出成形では、樹脂が金型が合わさった状態（型締め状態）の金型に流される。金型同士を合わせる際には、欲しい製品の形状となるように金型の両側から数トンから数千トンの力をかける必要がある。そのため、細長い金型は、大きな力が加わると力に耐えきれず、折れてしまい破損してしまう。また、樹脂は粘性流体であるため、金型内を流動させる際に樹脂を押し込む力が必要となり、金型に負荷がかかる。従って、表示光カバー１に形成される凹形状を片側のみに形成すると、射出成型時に用いる金型の凸箇所が破損する恐れがある。 The plate thickness of the display light cover 1 of the embodiment is basically formed to be about 2 mm. In FIG. 11, of the operating state display formed on the LED display portion 2 of the display light cover 1, the plate thickness of the portion 20 is about 1 mm, and the plate thickness of the portion 30 is about 2 mm. Since the plate thickness of the portion 20 is thin, the LED light 11 irradiated to the display light cover 1 is easily transmitted, and the LED light 11 is clearly recognized from the outside. Since the portion 30 is thicker than the portion 20, the LED light 11 irradiated to the display light cover 1 is difficult to transmit, and the LED light 11 looks vague. In order for the user to recognize the shape formed in the portion 20 of the display light cover 1 by the LED light 11 passing through the display light cover 1, the plate thickness of the portion 20 is set with respect to the plate thickness of the display light cover 1. It is desirable to make the plate thickness about half, about 1 mm. When a shape indicating an operating state is created on the LED display portion 2 of the display light cover 1 with a shape width of about 1 mm or less, an elongated mold shape is required for the injection molding machine. In injection molding, the resin is poured into a mold in a state where the mold is combined (mold tightening state). When matching the molds together, it is necessary to apply a force of several tons to several thousand tons from both sides of the mold so as to obtain the desired product shape. Therefore, when a large force is applied, the elongated mold cannot withstand the force and breaks and breaks. Further, since the resin is a viscous fluid, a force for pushing the resin is required when flowing in the mold, which imposes a load on the mold. Therefore, if the concave shape formed on the display light cover 1 is formed on only one side, the convex portion of the mold used at the time of injection molding may be damaged.
　表示光カバー１の片側の面の凹形状が浅くなると光度不足で表示が認識しづらくなる。従って、実施の形態の表示光カバー１は、両面に同一の凹形状を有している。図５に示すように、ＬＥＤ基板保持部品５の筒状部５＿１及び受光窓保持部品６の絞り部６＿２は、ＬＥＤ光１１により光らない部分４０を形成する。 If the concave shape of one side of the display light cover 1 becomes shallow, the display becomes difficult to recognize due to insufficient light intensity. Therefore, the display light cover 1 of the embodiment has the same concave shape on both sides. As shown in FIG. 5, the cylindrical portion 5_1 of the LED substrate holding component 5 and the diaphragm portion 6_2 of the light receiving window holding component 6 form a portion 40 that is not illuminated by the LED light 11.
　図１２は、実施の形態に係る空気調和機１０３の室内機１０１に設けられる表示光カバー１の下面を示す図である。図１２に示すように、表示光カバー１の下面には、ＬＥＤ表示部分２を有する。図１３は、実施の形態に係る空気調和機１０３の室内機１０１に設けられる表示光カバー１のＬＥＤ表示部分２の一例を示す図である。図１３において、表示光カバー１の裏面３及び表面４には、室内機１０１の運転状態を示す運転状態表示形状２＿１及び室内機１０１のその他の機能表示形状２＿２が形成されている。なお、ＬＥＤ表示部分２に形成される形状は、運転状態表示形状２＿１及び機能表示形状２＿２の形状に限られるものではない。また、ＬＥＤ表示部分２に形成される形状の数は、運転状態表示形状２＿１及び機能表示形状２＿２の２つに限られるものではない。 FIG. 12 is a diagram showing the lower surface of the display light cover 1 provided in the indoor unit 101 of the air conditioner 103 according to the embodiment. As shown in FIG. 12, an LED display portion 2 is provided on the lower surface of the display light cover 1. FIG. 13 is a diagram showing an example of the LED display portion 2 of the display light cover 1 provided in the indoor unit 101 of the air conditioner 103 according to the embodiment. In FIG. 13, the back surface 3 and the front surface 4 of the display light cover 1 are formed with an operating state display shape 2_1 indicating the operating state of the indoor unit 101 and another function display shape 2_2 of the indoor unit 101. The shape formed in the LED display portion 2 is not limited to the shapes of the operating state display shape 2_1 and the function display shape 2_1. Further, the number of shapes formed in the LED display portion 2 is not limited to the operating state display shape 2_1 and the function display shape 2_2.
　ＬＥＤ基板保持部品５及び受光窓保持部品６は、互いに複数の位置決め形状（図示せず）を有しており、ＬＥＤ基板保持部品５及び受光窓保持部品６の位置が収まるようになっている。位置決め形状は、表示光カバー１が有していても良い。 The LED board holding component 5 and the light receiving window holding component 6 have a plurality of positioning shapes (not shown), so that the positions of the LED board holding component 5 and the light receiving window holding component 6 can be accommodated. The positioning shape may be possessed by the display light cover 1.
　実施の形態に係る空気調和機１０３の室内機１０１は、ＬＥＤ光１１はＬＥＤ基板保持部品５の筒状部５＿１及び受光窓保持部品６の筒状部６＿１の内部を通過し、表示光カバー１に照射されて通過する。これにより、ユーザは、表示光カバー１のＬＥＤ表示部分２に形成された形状を認識することができ、その結果、空気調和機１０３の運転状態を認識することができる。 In the indoor unit 101 of the air conditioner 103 according to the embodiment, the LED light 11 passes through the inside of the cylindrical portion 5_1 of the LED substrate holding component 5 and the tubular portion 6_1 of the light receiving window holding component 6, and the display light cover 1 Is irradiated to pass through. As a result, the user can recognize the shape formed in the LED display portion 2 of the display light cover 1, and as a result, can recognize the operating state of the air conditioner 103.
　従って、実施の形態に係る空気調和機１０３の室内機１０１によれば、ＬＥＤに表示された室内機１０１の運転状態を示す形状が、表示光カバー１のＬＥＤ側の裏面３及び意匠側の表面４に形成される。従って、空気調和機１０３の室内機１０１に銘板付きのシールを貼り付ける必要がなく、室内機１０１の製作コストを削減すことができる。 Therefore, according to the indoor unit 101 of the air conditioner 103 according to the embodiment, the shape indicating the operating state of the indoor unit 101 displayed on the LED is the back surface 3 on the LED side and the front surface on the design side of the display light cover 1. It is formed in 4. Therefore, it is not necessary to attach a sticker with a name plate to the indoor unit 101 of the air conditioner 103, and the manufacturing cost of the indoor unit 101 can be reduced.
　また、室内機１０１の表面側に形状が設けられているので、ＬＥＤが点灯していなくても、使用者が運転状態等の表示位置及び運転状態の有無を認識可能である。 Further, since the shape is provided on the surface side of the indoor unit 101, the user can recognize the display position such as the operating state and the presence / absence of the operating state even if the LED is not lit.
　室内機１０１には、外部からの信号を受信する受光機（図示せず）を有するが、室内機１０１に対する外部からの信号は内部に光が漏れていると受信ができないことがある。実施の形態の室内機１０１によれば、ＬＥＤ光１１は筒状部５＿１及び筒状部６＿１の内部を通過し、表示光カバー１に照射されて通過する。このように筒状部５＿１及び筒状部６＿１を設けることにより、室内機１０１の内部に光が漏れることも防ぐことが可能であり、受光機（図示せず）への信号受信に対する影響を無くすことができる。 The indoor unit 101 has a receiver (not shown) for receiving a signal from the outside, but the signal from the outside to the indoor unit 101 may not be received if light leaks inside. According to the indoor unit 101 of the embodiment, the LED light 11 passes through the inside of the tubular portion 5_1 and the tubular portion 6_1, and is irradiated to the indicator light cover 1 to pass therethrough. By providing the cylindrical portion 5_1 and the tubular portion 6_1 in this way, it is possible to prevent light from leaking into the indoor unit 101 and eliminate the influence on signal reception to the receiver (not shown). be able to.
　また、ＬＥＤ基板保持部品５の筒状部５＿１及び受光窓保持部品６の筒状部６＿１が設けられる。表示光カバー１に形成される形状の板厚は、異なるように形成される。従って、図１１に示すように、形状は、はっきり認識可能な部分２０、ぼんやり見える部分３０及び光らない部分４０の３段階とすることができる。このような形状の表示を行うことにより、銘板付きのシールを使用せずにユーザに認識可能となり、部品の製作コスト及び作業工程を削減することが可能となる。 Further, a cylindrical portion 5_1 of the LED board holding component 5 and a tubular portion 6_1 of the light receiving window holding component 6 are provided. The plate thickness of the shape formed on the indicator light cover 1 is different. Therefore, as shown in FIG. 11, the shape can be in three stages: a clearly recognizable portion 20, a vaguely visible portion 30, and a non-shining portion 40. By displaying such a shape, it becomes possible for the user to recognize it without using a sticker with a name plate, and it is possible to reduce the manufacturing cost of parts and the work process.

The solid arrow shown in FIG. 14 indicates the flow direction of the refrigerant during the cooling operation. Further, the broken line arrow shown in FIG. 14 indicates the flow of the refrigerant during the heating operation.

The indoor unit 101 and the outdoor unit 102 are connected by a refrigerant pipe 400. The indoor unit 101 has an indoor heat exchanger 110. The outdoor unit 102 includes a compressor 210, a four-way valve 220, an outdoor heat exchanger 230, and an expansion valve 240.
　圧縮機２１０は、吸入した冷媒を圧縮して吐出する。ここで、特に限定するものではないが、圧縮機２１０は、例えばインバータ回路等によって運転周波数を任意に変化させることにより、圧縮機２１０の容量を変化してもよい。なお、圧縮機２１０の容量とは、単位時間あたりの冷媒を送り出す量を表すものである。四方弁２２０は、例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 compressor 210 compresses and discharges the sucked refrigerant. Here, although not particularly limited, the compressor 210 may change the capacity of the compressor 210 by arbitrarily changing the operating frequency by, for example, an inverter circuit or the like. The capacity of the compressor 210 represents the amount of the refrigerant delivered per unit time. The four-way valve 220 is a valve that switches the flow of the refrigerant between, for example, a cooling operation and a heating operation.
　室外熱交換器２３０は、冷媒と室外空気との熱交換を行う。室外熱交換器２３０は、暖房運転時においては蒸発器として機能し、冷媒を蒸発させて気化させる。また、室外熱交換器２３０は、冷房運転時においては凝縮器として機能し、冷媒を凝縮して液化させる。 The outdoor heat exchanger 230 exchanges heat between the refrigerant and the outdoor air. The outdoor heat exchanger 230 functions as an evaporator during the heating operation to evaporate and vaporize the refrigerant. Further, the outdoor heat exchanger 230 functions as a condenser during the cooling operation to condense and liquefy the refrigerant.
　膨張弁２４０は、冷媒を減圧して膨張させる。例えば、電子式膨張弁等で膨張弁２４０を構成した場合には、膨張弁２４０は、図示せぬ制御装置等の指示に基づいて開度調整が行われる。室内熱交換器１１０は、空調対象空間の空気と冷媒との熱交換を行う。室内熱交換器１１０は、暖房運転時においては凝縮器として機能し、冷媒を凝縮して液化させる。また、室内熱交換器１１０は、冷房運転時においては蒸発器として機能し、冷媒を蒸発させて気化させる。 The expansion valve 240 decompresses the refrigerant and expands it. For example, when the expansion valve 240 is configured by an electronic expansion valve or the like, the opening degree of the expansion valve 240 is adjusted based on an instruction from a control device or the like (not shown). The indoor heat exchanger 110 exchanges heat between the air in the air-conditioned space and the refrigerant. The indoor heat exchanger 110 functions as a condenser during the heating operation to condense and liquefy the refrigerant. Further, the indoor heat exchanger 110 functions as an evaporator during the cooling operation, and evaporates and vaporizes the refrigerant.
　以上のように構成された空気調和機１０３は、室外機１０２の四方弁２２０により冷媒の流れを切り換えることで、暖房運転及び冷房運転を実現することができる。 The air conditioner 103 configured as described above can realize the heating operation and the cooling operation by switching the flow of the refrigerant by the four-way valve 220 of the outdoor unit 102.
