Description

本発明は、空気調和機の室外機のトップパネルの構成に関するものである。 The present invention relates to a configuration of a top panel of an outdoor unit of an air conditioner.

従来、空気調和機の室外機は、熱交換器において冷媒と外気との間で熱交換を行うよう構成されている。室外機の内部には、外気を熱交換器に供給するファンが設けられており、ファンの前面側にはベルマウスが設けられている。熱交換器で冷媒と熱交換した外気は、ベルマウスを介して室外機の外方に排気される。このような室外機の筐体は、例えば、底面パネルと、前面パネルと、背面パネルと、サイドパネルと、トップパネルとを有している。 Conventionally, an outdoor unit of an air conditioner is configured to exchange heat between a refrigerant and outside air in a heat exchanger. Inside the outdoor unit, a fan that supplies outside air to the heat exchanger is provided, and a bell mouth is provided on the front side of the fan. The outside air that has exchanged heat with the refrigerant in the heat exchanger is exhausted to the outside of the outdoor unit via the bell mouth. The housing of such an outdoor unit has, for example, a bottom panel, a front panel, a back panel, a side panel, and a top panel.

戸外に設置される室外機のトップパネルには降雪時に雪が積もることがあり、気温の上昇と共にトップパネルに積もった雪が融け、その雪融け水が室外機の上部から前面パネルに流れてくる場合がある。また、降雨時にトップパネルに当たった雨水が室外機の上部から前面パネルに流れてくる場合がある。前面パネルに流れてくる雪融け水若しくは雨水の水分は、ワイヤーグリルと前面パネルの隙間からベルマウスへ浸入する。寒冷地においては、ベルマウスへ浸入した水分が外気温の低下に伴いベルマウスの上部で氷柱となる場合がある。その結果、氷柱がファンと干渉し異音を発生するという不具合が生じる。特許文献１に記載の室外機は、このような異音の発生を抑制するために、トップパネルが前方から後方へ傾斜している構成を有している。 Snow may accumulate on the top panel of the outdoor unit installed outdoors during snowfall, and as the temperature rises, the snow accumulated on the top panel melts, and the melted snow water may flow from the top of the outdoor unit to the front panel. be. In addition, rainwater that hits the top panel during rainfall may flow from the upper part of the outdoor unit to the front panel. Moisture from melted snow or rainwater flowing to the front panel penetrates into the bell mouth through the gap between the wire grill and the front panel. In cold regions, the water that has entered the bell mouth may form an icicle at the top of the bell mouth as the outside air temperature drops. As a result, there is a problem that the icicle interferes with the fan and generates an abnormal noise. The outdoor unit described in Patent Document 1 has a configuration in which the top panel is inclined from the front to the rear in order to suppress the generation of such abnormal noise.

特開２００１－１６５４７３号公報Japanese Unexamined Patent Publication No. 2001-165473

特許文献１に記載の室外機の構成によれば、上述の雪融け水若しくは雨水の水分は、トップパネルの前方から後方への傾斜により前面パネルには流れず、室外機の背面側に導かれる。そのため、ベルマウスの上部に氷柱が形成されることはなく、上述の異音が発生することはない。しかしながら、水分が室外機の背面側に導かれることにより、背面側に配置されている熱交換器に水分が付着してしまう。寒冷地においては、熱交換器に付着した水分が凍結することがあり、その結果、熱交換器への外気の供給が妨げられ、熱交換器の熱交換効率が低下するという課題がある。 According to the configuration of the outdoor unit described in Patent Document 1, the water content of the above-mentioned snow melt water or rainwater does not flow to the front panel due to the inclination from the front to the rear of the top panel, but is guided to the back side of the outdoor unit. .. Therefore, no icicles are formed on the upper part of the bell mouth, and the above-mentioned abnormal noise does not occur. However, when the water is guided to the back side of the outdoor unit, the water adheres to the heat exchanger arranged on the back side. In cold regions, the moisture adhering to the heat exchanger may freeze, and as a result, the supply of outside air to the heat exchanger is hindered, and there is a problem that the heat exchange efficiency of the heat exchanger is lowered.

本発明は、上記のような課題を解決するためになされたものであり、熱交換効率の低下を抑制すると共に、異音の発生を抑制することができる空気調和機の室外機を提供することを目的とする。 The present invention has been made to solve the above-mentioned problems, and to provide an outdoor unit of an air conditioner capable of suppressing a decrease in heat exchange efficiency and suppressing the generation of abnormal noise. With the goal.

本発明に係る空気調和機の室外機は、トップパネルと、底面パネルと、前記底面パネルに設けられ、前記トップパネルを支持している複数の外郭パネルと、前記トップパネルと前記底面パネルと前記複数の外郭パネルとで形成される筐体の背面側に配置されている熱交換器と、前記熱交換器に外気を供給するファンと備え、前記トップパネルは、前記筐体の左右方向に延びる第１縁部から、前記第１縁部と対向し、前記筐体の左右方向に延びる第２縁部に向けて、前記底面パネルの側へ傾斜しており、前記第２縁部は、平面視において、前記複数の外郭パネルのうち前記第２縁部が位置する側の外郭パネルよりも、前記筐体の外方に位置しており、前記第２縁部において、下方向に延びる壁部が形成され、前記筐体の内部は、左右方向において、前記ファンが設けられている送風機室と圧縮機が設けられている機械室に区分けされており、前記壁部の下端部は、前記送風機室から前記機械室へ向かって下方向へ傾斜している。 The outdoor unit of the air exchanger according to the present invention includes a top panel, a bottom panel, a plurality of outer panels provided on the bottom panel and supporting the top panel, the top panel, the bottom panel, and the above. A heat exchanger arranged on the back side of the housing formed by a plurality of outer panels and a fan for supplying outside air to the heat exchanger are provided, and the top panel extends in the left-right direction of the housing. The second edge portion is inclined toward the bottom panel toward the second edge portion facing the first edge portion and extending in the left-right direction of the housing, and the second edge portion is flat. Visually, the wall portion is located outside the housing and extends downward at the second edge portion of the plurality of outer panels, which is located on the outer side of the housing with respect to the outer panel on the side where the second edge portion is located. Is formed, and the inside of the housing is divided into a blower chamber provided with the fan and a machine chamber provided with the compressor in the left-right direction, and the lower end portion of the wall portion is the blower chamber. It is inclined downward from the chamber toward the machine chamber .

本発明に係る空気調和機の室外機によると、トップパネルが底面パネルの側へ傾斜しており、底面パネル側に傾斜している第２縁部は外郭パネルよりも筐体の外方へ延びているため、水分がトップパネルに付着しても、熱交換器及びファンに導かれることはない。従って、水分が熱交換器及びファンに氷結することはなく、熱交換器の熱交換効率の低下を抑制すると共に、異音の発生を抑制することができる。 According to the outdoor unit of the air conditioner according to the present invention, the top panel is inclined toward the bottom panel, and the second edge portion inclined toward the bottom panel extends outward from the outer panel rather than the outer panel. Therefore, even if moisture adheres to the top panel, it will not be guided to the heat exchanger and the fan. Therefore, moisture does not freeze on the heat exchanger and the fan, and it is possible to suppress a decrease in heat exchange efficiency of the heat exchanger and suppress the generation of abnormal noise.

FIG. 3 shows the outdoor unit 1 from the right side. In FIG. 3, the left side is the front side of the housing 10 of the outdoor unit 1, and the right side is the back side of the housing 10 of the outdoor unit 1. The top panel 20 is a triangular columnar member in which a pair of bottom surfaces 23 have a shape of a substantially right triangle. In other words, the vertical length of the first edge portion 21 of the top panel 20 is longer than the vertical length of the second edge portion 22.

トップパネル２０は、一対の底面２３が筐体１０の側面に位置するよう配置されている。一方の底面２３の斜辺である第１辺２３Ａは上側を向き、直角を挟む第２辺２３Ｂと第３辺２３Ｃのうち、短い方の第２辺２３Ｂは筐体１０の前面側を向き、長い方の第３辺２３Ｃは背面パネル６０の側面部６２の上端部と対向している。尚、他方の底面２３の第３辺２３Ｃは、送風機室パネル５０の側面部５２の上端部と対向している。一対の底面２３の第２辺２３Ｂは、筐体１０の前後方向において、筐体１０の前面、すなわち機械室正面パネル４０及び送風機室パネル５０の前面部５１と略同一の位置に位置している。一対の底面２３の第１辺２３Ａと第３辺２３Ｃが交差する頂点Ｐ１は、筐体１０の背面より外方に位置している。また、第２縁部２２は、図１に示すように、筐体１０の背面側の全領域に亘って、すなわち、送風機室１０Ａ側の左側面から機械室１０Ｂ側の右側面まで延びている。 The top panel 20 is arranged so that a pair of bottom surfaces 23 are located on the side surfaces of the housing 10. The first side 23A, which is the hypotenuse of one of the bottom surfaces 23, faces upward, and the shorter second side 23B of the second side 23B and the third side 23C sandwiching the right angle faces the front side of the housing 10 and is long. The third side 23C of the side faces the upper end portion of the side surface portion 62 of the back panel 60. The third side 23C of the other bottom surface 23 faces the upper end portion of the side surface portion 52 of the blower chamber panel 50. The second side 23B of the pair of bottom surfaces 23 is located at substantially the same position as the front surface of the housing 10, that is, the front surface portion 51 of the machine room front panel 40 and the blower room panel 50 in the front-rear direction of the housing 10. .. The apex P1 at which the first side 23A and the third side 23C of the pair of bottom surfaces intersect is located outside the back surface of the housing 10. Further, as shown in FIG. 1, the second edge portion 22 extends over the entire area on the back surface side of the housing 10, that is, from the left side surface on the blower room 10A side to the right side surface on the machine room 10B side. ..

このようにトップパネル２０を配置することにより、トップパネル２０の上面２０Ａは、第１縁部２１から第２縁部２２に向けて、すなわち、筐体１０の前面側から背面側へ向けて、底面パネル３０の側へ傾斜している。さらに、第２縁部２２は、筐体１０の前後方向において筐体１０の背面側の背面パネル６０の背面部６１よりも外方に位置している。 By arranging the top panel 20 in this way, the upper surface 20A of the top panel 20 is directed from the first edge portion 21 to the second edge portion 22, that is, from the front side to the back side of the housing 10. It is inclined toward the bottom panel 30. Further, the second edge portion 22 is located outward of the back surface portion 61 of the back panel 60 on the back side of the housing 10 in the front-rear direction of the housing 10.

トップパネルに付着した水分が筐体の前面側に流れると、水分は送風機室パネルの前面側へ伝わる。そして、前面側へ伝わった水分は、前面側のパネルとワイヤーグリルとの隙間からベルマウス浸入する場合がある。寒冷地において外気の温度が下がると、ベルマウスへ浸入した水分は氷柱となり、ファンと干渉し、異音が発生する。しかしながら、本実施の形態１によれば、トップパネル２０の上面２０Ａは筐体１０の前面側から背面側へ向けて底面パネル３０の側へ傾斜しているため、トップパネル２０に付着した水分は、筐体１０の前面側には流れず、背面側に流れる。従って、このような異音の発生を抑制することができる。 When the moisture adhering to the top panel flows to the front side of the housing, the moisture is transmitted to the front side of the blower chamber panel. Then, the water transmitted to the front side may infiltrate the bell mouth through the gap between the panel on the front side and the wire grill. When the temperature of the outside air drops in a cold region, the moisture that has entered the bell mouth becomes an icicle, which interferes with the fan and generates abnormal noise. However, according to the first embodiment, since the upper surface 20A of the top panel 20 is inclined toward the bottom panel 30 from the front side to the back side of the housing 10, the moisture adhering to the top panel 20 is present. , It does not flow to the front side of the housing 10, but flows to the back side. Therefore, it is possible to suppress the generation of such abnormal noise.

また、背面側に流れる水分は、第２縁部２２から下方へ落下するが、本実施の形態１によれば、トップパネル２０の第２縁部２２は、筐体１０の背面側において、背面パネル６０の背面部６１よりも外方に位置している。従って、第２縁部２２から落下した水分が熱交換器１００に付着することが抑制される。その結果、熱交換器１００に付着した水分が凍結することにより起因する熱交換効率の低下を抑制することができる。 Further, the water flowing to the back surface side falls downward from the second edge portion 22, but according to the first embodiment, the second edge portion 22 of the top panel 20 is the back surface on the back surface side of the housing 10. It is located outside the back surface portion 61 of the panel 60. Therefore, it is possible to prevent the water that has fallen from the second edge portion 22 from adhering to the heat exchanger 100.

図８は、本発明の実施の形態２に係る空気調和機の室外機を側面から概念的に示す図である。実施の形態１と同様の部材には、図１～図７における符号と同一の符号が付されている。図８は、室外機２を右側面から示している。室外機２のトップパネル１５０は、実施の形態１と同様、全体として略三角柱の形状を有している。トップパネル１５０の筐体１０の前面側の第１縁部１５１及び筐体１０の背面側の第２縁部１５２は、筐体１０の左右方向に延びている。第１縁部１５１及び第２縁部１５２は、上述の実施の形態１と同様、筐体１０の背面側の全領域に亘って、すなわち、図２に示す送風機室１０Ａ側の左側面から機械室１０Ｂ側の右側面まで延びている。Embodiment 2.
FIG. 8 is a diagram conceptually showing the outdoor unit of the air conditioner according to the second embodiment of the present invention from the side surface. The same members as those in the first embodiment are designated by the same reference numerals as those shown in FIGS. 1 to 7. FIG. 8 shows the outdoor unit 2 from the right side. The top panel 150 of the outdoor unit 2 has a substantially triangular prism shape as a whole, as in the first embodiment. The first edge portion 151 on the front side of the housing 10 of the top panel 150 and the second edge portion 152 on the back side of the housing 10 extend in the left-right direction of the housing 10. The first edge portion 151 and the second edge portion 152 are machined over the entire area on the back surface side of the housing 10, that is, from the left side surface on the blower chamber 10A side shown in FIG. 2, as in the first embodiment. It extends to the right side of the room 10B side.

第２縁部１５２には下方向へ垂直に延びる壁部１５３が設けられている。壁部１５３は、筐体１０の左右方向において、第２縁部１５２と同一の長さを有している。すなわち、壁部１５３は、筐体１０の背面側の全領域に亘って、図２に示す送風機室１０Ａ側の左側面から機械室１０Ｂ側の右側面まで延びている。その他の構成は、実施の形態１と同様である。 The second edge portion 152 is provided with a wall portion 153 that extends vertically downward. The wall portion 153 has the same length as the second edge portion 152 in the left-right direction of the housing 10. That is, the wall portion 153 extends from the left side surface of the blower room 10A side shown in FIG. 2 to the right side surface of the machine room 10B side over the entire area on the back surface side of the housing 10. Other configurations are the same as those in the first embodiment.

本実施の形態２によれば、トップパネル１５０の背面側に流れる水分は、壁部１５３に導かれて落下するため、水分の落下地位を確定することができる。従って、水分の落下方向が乱れて、熱交換器１００の近傍へ水分が回り込むことが抑制される。その結果、熱交換器１００に水分が付着し凍結することに起因する熱交換効率の低下を、より効果的に抑制することができる。また、室外機１の背面側から前面側に向かって風が吹いている場合、背面側に流れてきた水分がトップパネル１５０の第２縁部１５２の裏面を伝って、背面パネル６０の背面部６１へ到達してしまうことが抑制される。従って、室外機１の背面側から前面側に向かって風が吹いている場合であっても、熱交換器１００に水分が付着し凍結することに起因する熱交換効率の低下を抑制することができる。 According to the second embodiment, the water flowing on the back surface side of the top panel 150 is guided by the wall portion 153 and falls, so that the falling position of the water can be determined. Therefore, the falling direction of the water is disturbed, and the water is suppressed from sneaking into the vicinity of the heat exchanger 100. As a result, it is possible to more effectively suppress the decrease in heat exchange efficiency due to the adhesion of moisture to the heat exchanger 100 and freezing. Further, when the wind is blowing from the back side to the front side of the outdoor unit 1, the moisture flowing to the back side is transmitted to the back surface of the second edge portion 152 of the top panel 150, and the back portion of the back panel 60 is formed. Reaching 61 is suppressed. Therefore, even when the wind is blowing from the back side to the front side of the outdoor unit 1, it is possible to suppress the decrease in heat exchange efficiency due to the adhesion of moisture to the heat exchanger 100 and freezing. can.

Further, the extension portion 122 of the top panel 120 of the second modification of the first embodiment may be provided with the same wall portion as the wall portion 153.

FIG. 9 is a diagram conceptually showing the outdoor unit of the air conditioner according to the third embodiment of the present invention from the back. The same members as those in the first embodiment are designated by the same reference numerals as those shown in FIGS. 1 to 7. The top panel 160 of the outdoor unit 3 has a substantially triangular prism shape as a whole, like the top panel 20 of the first embodiment and the top panel 150 of the second embodiment. Further, the second edge portion 162 on the back side of the housing 10 of the top panel 160 has the same mode as that shown in FIGS. 3 and 8, and the back surface of the back panel 60 is on the back side of the housing 10. It is located outside the portion 61.

第２縁部１６２には壁部１６３が形成されている。壁部１６３は、セパレータ１１により区分けされている送風機室１０Ａから機械室１０Ｂへ向かって、底面パネル３０へ向かう方向、すなわち下方向へ傾斜している。換言すると、壁部１６３の下端部の上下方向における位置は、送風機室１０Ａから機械室１０Ｂへ向かって、上下方向において漸次低くなっている。 A wall portion 163 is formed on the second edge portion 162. The wall portion 163 is inclined downward from the blower chamber 10A separated by the separator 11 toward the bottom panel 30 toward the machine chamber 10B. In other words, the position of the lower end portion of the wall portion 163 in the vertical direction is gradually lowered in the vertical direction from the blower chamber 10A to the machine chamber 10B.

本実施の形態３によれば、送風機室１０Ａの風路を妨げることなく、水分を機械室１０Ｂ側へ導くことができる。従って、熱交換器１００への外気の供給量を低下させることなく、熱交換器１００における水分の凍結を抑制することができ、熱交換器１００の熱交換効率の低下をより効果的に抑制できる。 According to the third embodiment, moisture can be guided to the machine room 10B side without obstructing the air passage of the blower room 10A. Therefore, it is possible to suppress the freezing of water in the heat exchanger 100 without reducing the amount of outside air supplied to the heat exchanger 100, and it is possible to more effectively suppress the decrease in the heat exchange efficiency of the heat exchanger 100. ..

FIG. 10 is a perspective view of the outdoor unit of the air conditioner according to the fourth embodiment of the present invention. FIG. 11 is a diagram conceptually showing the outdoor unit of the air conditioner according to the fourth embodiment of the present invention from the side surface. FIG. 11 shows the outdoor unit 4 from the right side. In FIGS. 10 and 11, the same members as those in the first embodiment are designated by the same reference numerals as those in FIGS. 1 to 7. The top panel 20 of the outdoor unit 4 has the configuration described in the first embodiment. The difference between the first embodiment and the fourth embodiment is the arrangement of the top panel 20. In the fourth embodiment, the first side 23A, which is the hypotenuse of one of the bottom surfaces 23, faces upward, and the shorter second side 23B of the second side 23B and the third side 23C sandwiching the right angle is the housing 10. The longer third side 23C faces the upper end of the side surface 62 of the back panel 60. The third side 23C of the other bottom surface 23 faces the upper end portion of the side surface portion 52 of the blower chamber panel 50. The second side 23B of the pair of bottom surfaces 23 is located at substantially the same position as the back surface of the housing 10, that is, the back surface portion 61 of the back panel 60 in the front-rear direction of the housing 10. The apex P1 at which the first side 23A and the third side 23C of the pair of bottom surfaces intersect is located outside the front surface of the housing 10, that is, the front surface portion 51 of the machine room front panel 40 and the blower room panel 50. .. Further, in the fourth embodiment, the apex P1 is located outside the first wire grill 93 and the second wire grill 94. Other configurations are the same as those in the first embodiment.

このようにトップパネル２０を配置することにより、トップパネル２０の上面２０Ａは、第１縁部２１から第２縁部２２に向けて、すなわち筐体１０の背面側から前面側へ向けて、底面パネル３０の側へ傾斜している。さらに、第２縁部２２は筐体１０の前面側において、機械室正面パネル４０及び送風機室パネル５０の前面部５１よりも外方に位置している。 By arranging the top panel 20 in this way, the upper surface 20A of the top panel 20 has a bottom surface from the first edge portion 21 toward the second edge portion 22, that is, from the back surface side to the front surface side of the housing 10. It is tilted toward the panel 30. Further, the second edge portion 22 is located on the front side of the housing 10 outside the front portion 51 of the machine room front panel 40 and the blower room panel 50.

本実施の形態４によれば、トップパネル２０に付着した水分が背面側に流れることが抑制される。従って、前面側に流れる熱交換器１００に付着した水分が凍結することにより起因する熱交換効率の低下を抑制することができる。 According to the fourth embodiment, the moisture adhering to the top panel 20 is suppressed from flowing to the back surface side. Therefore, it is possible to suppress a decrease in heat exchange efficiency caused by freezing of the water adhering to the heat exchanger 100 flowing on the front surface side.

さらに、トップパネル２０の前面側に流れる水分は、第２縁部２２から下方へ落下するが、本実施の形態４によれば、トップパネル２０の第２縁部２２は筐体１０の前面側において外方へ延びている。従って、第２縁部２２から落下した水分が送風機室パネル５０の前面部５１へ伝わることが抑制される。すなわち、前面部５１へ伝わった水分が、図２に示す第１ベルマウス９１及び第２ベルマウス９２へ浸入することが抑制される。その結果、第１ベルマウス９１及び第２ベルマウス９２へ浸入した水分が氷柱となり、第１ファン１０１及び第２ファン１０２と干渉することにより起因する、異音の発生を抑制することができる。 Further, the water flowing to the front side of the top panel 20 falls downward from the second edge portion 22, but according to the fourth embodiment, the second edge portion 22 of the top panel 20 is on the front side of the housing 10. Extends outward in. Therefore, it is suppressed that the moisture dropped from the second edge portion 22 is transmitted to the front portion 51 of the blower chamber panel 50. That is, the water transmitted to the front surface portion 51 is suppressed from invading the first bell mouth 91 and the second bell mouth 92 shown in FIG. As a result, the water infiltrated into the first bell mouth 91 and the second bell mouth 92 becomes an icicle, and it is possible to suppress the generation of abnormal noise caused by interfering with the first fan 101 and the second fan 102.
