Description

本発明は、ガスクーラーを備えた給湯室外機に関するものである。   The present invention relates to a hot water supply outdoor unit equipped with a gas cooler.

従来の給湯室外機は、本体の底板となるユニットベースと、ユニットベース上に設置されガスクーラーを収納するケースと、ケースを覆い、上面が平らなカバーとを有している（たとえば、特許文献１参照）。   A conventional hot water supply outdoor unit has a unit base that is a bottom plate of a main body, a case that is installed on the unit base and stores a gas cooler, and a cover that covers the case and has a flat upper surface (for example, Patent Documents). 1).

特開２００９−１５０６４７号公報（図２）JP 2009-150647 A (FIG. 2)

従来の給湯室外機は、ガスクーラーカバーの上に雨水が滞留しそのまま氷結する恐れがある。氷結した雨水は前面パネルのベルマウスとブリッジし、送風ファンと干渉して異音を発生する原因となる。   In a conventional hot water supply outdoor unit, rainwater may accumulate on the gas cooler cover and freeze as it is. The frozen rainwater bridges with the bell mouth on the front panel, causing interference with the blower fan and causing abnormal noise.

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、その目的とするところは、ガスクーラーカバー上に雨水が滞留せずに排水できる、給湯室外機を得ることにある。   The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a hot water supply outdoor unit that can drain rainwater without staying on the gas cooler cover.

また、雨水の排水経路を特定するとともに確実にユニットベース内に排水することで、雨水の排水をガスクーラーの水漏れと錯誤されないようにする給湯室外機を得ることを目的とする。   It is another object of the present invention to provide a hot water supply outdoor unit that specifies a drainage path for rainwater and reliably drains the rainwater into the unit base so that the drainage of rainwater is not mistaken for a water leak from a gas cooler.

本発明に係る給湯室外機は、本体の底板となるユニットベースと、ユニットベース上に設置され、ガスクーラーを収納するケースと、ケースを覆うカバーとを備えた給湯室外機であって、
前記カバーは、上面が下方向へ傾斜した傾斜面を有し、かつ、前記傾斜面に雨水の排水径路を特定するガイド突起を設けたものである。 A hot water supply outdoor unit according to the present invention is a hot water supply outdoor unit that includes a unit base that is a bottom plate of a main body, a case that is installed on the unit base, and that houses a gas cooler, and a cover that covers the case,
The cover has an inclined surface whose upper surface is inclined downward, and is provided with a guide protrusion for specifying a drainage path of rainwater on the inclined surface.

本発明の給湯室外機は、ユニットベース内に収納するガスクーラカバーに傾斜を設け、その傾斜面に雨水の排水径路を特定するガイド突起を設けたので、ガスクーラーカバー上に侵入した雨水の排水が容易にできるという効果を有する。   In the hot water supply outdoor unit of the present invention, the gas cooler cover stored in the unit base is provided with an inclination, and a guide projection for specifying the drainage path of the rainwater is provided on the inclined surface. It has the effect that it can be done easily.

1 is a front view of a hot water outdoor unit according to Embodiment 1 of the present invention, FIG. 2 is a perspective view showing a part of the hot water outdoor unit, and FIG. 3 is an exploded perspective view of a gas cooler case of the hot water outdoor unit. FIG. 4 is a cross-sectional side view of the hot water supply outdoor unit as seen from the side.
In the figure, a hot water supply outdoor unit 10 has a main body 1 formed of a box-shaped casing. The main body 1 accommodates a compressor 11, a water circulation pump (not shown), a gas cooler 3, an evaporator 12, a blower fan 13, a fan motor 14, and the like, which are main components of the hot water supply outdoor unit 10. Further, a front panel 16 provided with a blowing grill 15 is installed on the front surface of the main body 1, and a bell mouth 17 is provided between the blowing grill 15 and the blower fan 13 to form an outlet. The evaporator 12 is bent in a substantially L shape, and suction ports (not shown) are provided on the side surface and the back surface of the main body 1 corresponding to the evaporator 12. In FIGS. 1 and 4, reference numeral 18 denotes a drain port.
As shown in FIG. 3, the gas cooler 3 is accommodated in a gas cooler case 4 installed on a unit base 2 that is a bottom plate of the main body 1. The upper portion of the gas cooler case 4 is covered with a gas cooler cover 6 via a heat insulating cover 5.

ガスクーラカバー６は、上面が下方向へ傾斜した傾斜面６ａを有し、その傾斜面６ａ上に、図２に矢印２０で示すように、雨水を特定方向へ流下させる、つまり雨水の排水径路を特定するガイド突起７（ビードとも呼ばれる）が設けられている。ガスクーラカバー６に一体の凸部により形成されるガイド突起７は、図示の形状に限定するものではないが、例えば逆Ｖの字状に形成されており、傾斜面６ａの下端縁部に沿って少なくとも１つ以上配置されている。   The gas cooler cover 6 has an inclined surface 6a whose upper surface is inclined downward. On the inclined surface 6a, as shown by an arrow 20 in FIG. 2, rainwater flows down in a specific direction, that is, a rainwater drainage path is provided. A guide protrusion 7 (also referred to as a bead) is provided. The guide protrusion 7 formed by the convex part integral with the gas cooler cover 6 is not limited to the shape shown in the figure, but is formed, for example, in an inverted V shape, along the lower edge of the inclined surface 6a. At least one or more are arranged.

また、ガスクーラーカバー６は、傾斜面６ａから前面下方へ垂直に垂下する前面部６ｂを有し、前面部６ｂの中央部にはユニットベース２にネジで固定されるネジ止め部６ｃが設けられている。ネジ止め部６ｃの腐食を防ぐため、上記ガイド突起７は、雨水がこのネジ止め部６ｃを避けて流れ落ちるように、すなわちネジ止め部６ｃに雨水の排水径路が当たらないように、ネジ止め部６ｃの上方の傾斜面６ａ下端縁部の位置に必ず１つは設けられている。また、ネジ止め部６ｃに雨水がかからないようにすればよいので、ガイド突起７の形状は逆Ｕの字状や円弧状等に形成してもよい。   The gas cooler cover 6 has a front surface portion 6b that vertically hangs downward from the inclined surface 6a. A screwing portion 6c that is fixed to the unit base 2 with a screw is provided at the center of the front surface portion 6b. ing. In order to prevent corrosion of the screwing portion 6c, the guide protrusion 7 is provided with the screwing portion 6c so that the rainwater flows down avoiding the screwing portion 6c, that is, the rainwater drainage path does not hit the screwing portion 6c. One is always provided at the lower end edge of the inclined surface 6a. Further, since it is sufficient that rainwater is not applied to the screwing portion 6c, the shape of the guide protrusion 7 may be formed in an inverted U shape, an arc shape, or the like.

次に動作について説明する。
上記のように構成された給湯室外機１０においては、雨水が前面パネル１６の吹き出しグリル１５を通してガスクーラーカバー６上に滴下した場合は、図２および図４に矢印で示すように、ガスクーラーカバー６の傾斜面６ａに沿って雨水は流れ落ち、その傾斜面６ａ上に設けられたガイド突起７により雨水は特定の方向に案内されつつ流下し、ユニットベース２内に回収される。
このように、ガイド突起７により排水が誘導されるため、ネジ止め部６ｃに雨水が接触することはない。
また、ユニットベース２内に回収された雨水はドレン排水とともに、ユニットベース２より機外に排出される。 Next, the operation will be described.
In the hot water supply outdoor unit 10 configured as described above, when rainwater drops on the gas cooler cover 6 through the blowout grill 15 of the front panel 16, as shown by arrows in FIGS. 2 and 4, the gas cooler cover The rainwater flows down along the inclined surface 6 a of 6, and the rainwater flows down while being guided in a specific direction by the guide protrusion 7 provided on the inclined surface 6 a, and is collected in the unit base 2.
As described above, since the drainage is guided by the guide protrusion 7, rainwater does not contact the screwing portion 6 c.
Further, the rainwater collected in the unit base 2 is discharged from the unit base 2 to the outside of the apparatus together with the drainage.

以上のように、本実施の形態の給湯室外機１０では、ガスクーラーカバー６に滴下した雨水を傾斜面６ａに沿って排水するようにしているので、排水が容易で、また傾斜面６ａに設けたガイド突起７により排水方向が特定できるため、ユニットベース２への排水が確実にできる。また、雨水がガスクーラーカバー６上に保持されないため、従来のようにそのまま氷結することがなく、前面パネル１６のベルマウス１７との間でブリッジし送風ファン１３と干渉することがない。
従来の場合は、ガスクーラーカバーの上面が平らでベルマウス１６との間の距離も近いため、図４のＡ部で示す箇所で氷結を起こしていたものである。
本実施の形態によればこの氷結の発生を防止できる効果がある。また、雨水の排水径路が特定されるため、雨水の排水をガスクーラーカバー６の水漏れと錯誤されることがない。 As described above, in the hot water supply outdoor unit 10 according to the present embodiment, rainwater dripped onto the gas cooler cover 6 is drained along the inclined surface 6a. Since the drainage direction can be specified by the guide projection 7, the drainage to the unit base 2 can be ensured. Further, since rainwater is not held on the gas cooler cover 6, it does not freeze as it is in the prior art, and bridges with the bell mouth 17 of the front panel 16 and does not interfere with the blower fan 13.
In the conventional case, since the upper surface of the gas cooler cover is flat and the distance from the bell mouth 16 is also short, icing has occurred at the location indicated by part A in FIG.
According to the present embodiment, there is an effect of preventing the occurrence of freezing. Further, since the rainwater drainage path is specified, the drainage of the rainwater is not mistaken for the water leak of the gas cooler cover 6.
