Description

【0001】
【発明の属する技術分野】
本発明は、製氷機等において生じた比較的低温の排水に対するトラップの構造に関する。
【0002】
【従来の技術】
製氷機等における排水トラップは、排水路中の上下に短く屈曲したトラップ部に排水の一部を貯留させて、機外へ冷気が流出したり、あるいは、機外から塵埃や異臭、虫等が侵入することを防止するようにしているが、製氷機等における製氷残水や溶氷水は比較的低温のため、これらの低温水が排水としてトラップ部に貯留されると、トラップ部の表面に外気からの結露が発生しやすい。
【0003】
このため、従来は、トラップ部の表面を断熱材で厚く覆って、上記結露の発生を防止するようにしているが、この場合、排水の一部が貯留される下方湾曲部のみを断熱材で覆うことは実際上困難であるため、トラップ部全体を断熱材で覆うこととなる結果、比較的多量の断熱材を必要とするためコストアップを招くと共に、断熱材を取り付けるためにトラップ部の周囲に余分なスペースを形成させなければならず、また、トラップ部全体が断熱材で覆われているので、トラップ部内のつまりを外部から確認することは全く不可能であった。
【0004】
【発明が解決しようとする課題】
本発明の目的は、排水トラップにおいて、上下に短く屈曲したトラップ部の周囲に断熱材を取り付ける必要性を排除することにある。
【0005】
【課題を解決するための手段】
このため、本発明にかかる排水トラップは、上下に短く屈曲したトラップ部における下方湾曲部の下方に、上記下方湾曲部と間隔をおいて上記トラップ部と一体的に水滴受けが設けられている。
【0006】
従って、トラップ部の下方湾曲部内に排水の一部が貯留されて、下方湾曲部の表面と外気との温度差により下方湾曲部の表面に結露が生じても、その結露水の滴下は下方湾曲部の下方に間隔をおいて設けられた水滴受けにより受け止めることができるので、従来のようにトラップ部の表面に断熱材を取り付ける必要性を簡単に排除することができる。
【0007】
【発明の実施の形態】
以下、図面に示す本発明の各実施形態例について、同等部分にはそれぞれ同一符号を付けて説明する。
図1及び図2において、製氷機1の上部には図示しない製氷部と貯氷室2が設けられ、製氷機1の下部は冷媒圧縮機3、送風機4、凝縮器5等を収容した機械室6を構成していて、機械室6の前面開口7には図示しないカバーが着脱自在に取り付けられている。
【0008】
貯氷室2の底面隅部には、貯氷室2内の溶氷水を流出させるための排水ホース8が接着されると共に、上方の製氷部における排水皿から製氷残水を導く排水パイプ9の下端が排水ホース8内に開口している。
また、機械室6の背面を排水管10が貫通し、排水管10の外側先端が機外の排水溝11上に開口している。
【0009】
透明な樹脂製の排水トラップ12は上下に短く屈曲したトラップ部13をそなえ、排水トラップ12の上端が機械室6内に位置する排水ホース8下端に接続されると共に、排水トラップ12の下端が排水管10の一端に接続され、排水ホース8によって排水トラップ12へ導かれた溶氷水や、排水ホース8によって排水トラップ12へ導かれた製氷残水の一部がトラップ部13の下方湾曲部14内に貯留している。
【0010】
また、排水トラップ12には、下方湾曲部14の表面と間隔をおいて下方湾曲部14を全体的に覆う椀状の水滴受け15が一体成形されており、トラップ部13の下流側である下部流路12´の壁面に穴16が設けられて、穴16により水滴受け15の底部と上記下部流路12´内とが連通している。
【0011】
上記装置において、トラップ部13の下方湾曲部14内に貯留された溶氷水や製氷残水の排水は比較的低温のため、とくに、下方湾曲部14の表面に外気からの結露が発生しやすいが、この結露水が下方湾曲部14から滴下すれば、下方湾曲部14の下方に配置された水滴受け15により受け止められ、水滴受け15の底部から穴16を通って排水トラップ12の下部流路12´内へ確実に流入し、排水管10から排水溝11へ排出されることとなる。
また、下方湾曲部14に隣接したトラップ部13の縦壁面に結露水が生じても、その結露水は上記縦壁面に沿って流下することにより水滴受け15に受け止められ、水滴受け15の底部から穴16を通って上記と同様に、排水トラップ12の下部流路12´内へ排出される。
【0012】
従って、排水トラップ12におけるトラップ部13の周囲に断熱材を取り付ける必要は全くないため、排水トラップ12のコストダウンを容易に達成できると同時に、トラップ部13の周囲には断熱材を取り付けるための余分なスペースも不要となって、狭い機械室6内に排水トラップ12を配置する自由度が大きい長所がある。
【0013】
また、トラップ部13の周囲に断熱材が取り付けられていないと共に、排水トラップ12は全体が透明な樹脂製であるため、トラップ部13内にごみ等が堆積して排水トラップ12をつまらせれば、その状態を外部から確認することができるので、排水トラップ12を排水ホース8及び排水管10から適宜取り外す等によって排水トラップ12内を清掃し、上記つまりを確実に除去することができて、非常に便利である。
【0014】
なお、上記のように水滴受け15の底部と排水トラップ12内とを連通する穴16が設けられていても、排水トラップ12は機械室6内に配置されているので、排水溝11から排水トラップ12内へ流入した異臭等が、排水トラップ12を経て製氷部や貯氷室2に達することは全くないものである。
【0015】
図3に示す実施形態例は、排水トラップ12に一体成形された椀状の水滴受け15が比較的浅くて、下方湾曲部14の下面と間隔をおいて配置され、下方湾曲部14の前方を覆ってはいないため、上記実施形態例と同等の作用効果を奏することができる外、排水トラップ12内のつまり状態を上記実施形態例の場合以上に外部から容易に確認できる利点があり、また、水滴受け15が比較的小型のため、排水トラップ12の製造コストを一層低減させることが可能となる。
【0016】
さらに、図4に示す実施形態例においては、椀状の水滴受け15が排水トラップ12と一体成形されて、下方湾曲部14の下面と間隔をおいて配置されている一方、排水トラップ12の下部流路12´から分岐するトラップ部20が水滴受け15内で下方に向かって延び、トラップ部20の下端が水滴受け15底部の貯留水21中に浸漬されている。
【0017】
従って、下方湾曲部14の表面に生じた外気からの結露水は下方湾曲部14から水滴受け15底部の貯留水21中に滴下すると、トラップ部20内を逐次通って排水トラップ12の下部流路12´内に流入し、排水管10から排水溝11へと排出されるので、上記各実施形態例と同等の作用効果を奏することができると共に、排水溝11から排水トラップ12内へ流入した異臭等が機械室6内に達することは、トラップ部20によって確実に防止することができる長所がある。
なお、水滴受け15の外表面に生じた外気からの結露水は、排水トラップ下部流路12´の外面を伝わって下方へ流れるが、結露水の流下範囲が限定されていると同時に、結露水が滴下して飛散することもないため、その処置は簡単に行うことが可能である。
【0018】
【発明の効果】
本発明にかかる排水トラップにあっては、下方湾曲部の表面に生じた結露水を下方に設けられた水滴受けにより受け止めることができて、トラップ部の周囲に断熱材を取り付ける必要性が全くないため、排水トラップのコスト低減を容易に図ることができる長所がある。

BACKGROUND OF THE INVENTION
The present invention relates to a trap structure for relatively low temperature drainage generated in an ice making machine or the like.
[0002]
[Prior art]
Drain traps in ice makers, etc., store part of the drainage in trap sections that are bent vertically in the drainage channel, causing cool air to flow out of the machine, or for dust, off-flavours, insects, etc. from outside the machine. Although the ice making residual water and the melted ice water in ice makers and the like are relatively low in temperature, if these low-temperature water is stored in the trap part as drainage, the outside air is Condensation is likely to occur.
[0003]
For this reason, conventionally, the surface of the trap portion is covered with a heat insulating material to prevent the occurrence of the condensation, but in this case, only the downward curved portion where a part of the drainage is stored is covered with the heat insulating material. Since it is practically difficult to cover, the entire trap part is covered with a heat insulating material, and as a result, a relatively large amount of heat insulating material is required, resulting in an increase in cost and the surrounding of the trap part for attaching the heat insulating material. In addition, an extra space must be formed, and since the entire trap portion is covered with a heat insulating material, it is impossible to confirm the clogging in the trap portion from the outside.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to eliminate the necessity of attaching a heat insulating material around a trap portion that is bent vertically short in a drain trap.
[0005]
[Means for Solving the Problems]
For this reason, the drain trap according to the present invention is provided with a water droplet receiver integrally with the trap portion below the lower curved portion of the trap portion that is bent vertically shortly.
[0006]
Therefore, even if a part of the drainage is stored in the lower curved portion of the trap portion and condensation occurs on the surface of the lower curved portion due to the temperature difference between the surface of the lower curved portion and the outside air, the dripping of the condensed water is bent downward. Since it can be received by a water droplet receiver provided at an interval below the portion, the necessity of attaching a heat insulating material to the surface of the trap portion as in the prior art can be easily eliminated.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
In the following, each embodiment of the present invention shown in the drawings will be described with the same reference numerals given to the equivalent parts.
1 and 2, an ice making unit (not shown) and an ice storage chamber 2 are provided in the upper part of the ice making machine 1, and the lower part of the ice making machine 1 is a machine room 6 containing a refrigerant compressor 3, a blower 4, a condenser 5, and the like. A cover (not shown) is detachably attached to the front opening 7 of the machine room 6.
[0008]
At the bottom corner of the ice storage chamber 2, a drain hose 8 for allowing the melted ice water in the ice storage chamber 2 to flow out is bonded, and the lower end of the drain pipe 9 that guides the ice making residual water from the drain tray in the upper ice making section is The drain hose 8 is opened.
Further, a drain pipe 10 penetrates the back surface of the machine room 6, and an outer end of the drain pipe 10 is opened on a drain groove 11 outside the machine.
[0009]
The transparent resin drain trap 12 has a trap portion 13 that is bent up and down, the upper end of the drain trap 12 is connected to the lower end of the drain hose 8 located in the machine room 6, and the lower end of the drain trap 12 is drained. A part of the ice-melted water connected to one end of the pipe 10 and led to the drain trap 12 by the drain hose 8 or a part of the ice making residual water led to the drain trap 12 by the drain hose 8 is in the downward curved portion 14 of the trap portion 13. It is stored in.
[0010]
Further, the drain trap 12 is integrally formed with a bowl-shaped water drop receiver 15 that covers the entire lower curved portion 14 at a distance from the surface of the lower curved portion 14, and is a lower portion downstream of the trap portion 13. A hole 16 is provided in the wall surface of the channel 12 ′, and the bottom of the water droplet receiver 15 communicates with the inside of the lower channel 12 ′ through the hole 16.
[0011]
In the above apparatus, since the drainage of the melted ice water and the ice making residual water stored in the lower curved portion 14 of the trap portion 13 is relatively low temperature, dew condensation from outside air tends to occur particularly on the surface of the lower curved portion 14. If the condensed water drops from the downward curved portion 14, the condensed water is received by the water droplet receiver 15 disposed below the downward curved portion 14, and passes through the hole 16 from the bottom of the water droplet receiver 15 to the lower flow path 12 of the drain trap 12. It surely flows into ′ and is discharged from the drain pipe 10 to the drain groove 11.
Further, even if condensed water is generated on the vertical wall surface of the trap portion 13 adjacent to the lower curved portion 14, the condensed water is received by the water droplet receiver 15 by flowing along the vertical wall surface, and from the bottom of the water droplet receiver 15. Through the hole 16, it is discharged into the lower flow path 12 ′ of the drain trap 12 in the same manner as described above.
[0012]
Accordingly, since there is no need to attach a heat insulating material around the trap portion 13 in the drain trap 12, the cost of the drain trap 12 can be easily reduced, and at the same time, an extra portion for attaching a heat insulating material around the trap portion 13 In addition, there is an advantage that a large degree of freedom is required to dispose the drain trap 12 in the narrow machine room 6.
[0013]
In addition, since the insulating material is not attached around the trap portion 13 and the drain trap 12 is entirely made of a transparent resin, if dust or the like is accumulated in the trap portion 13 and the drain trap 12 is caught, Since the state can be confirmed from the outside, the inside of the drain trap 12 can be cleaned by removing the drain trap 12 from the drain hose 8 and drain pipe 10 as appropriate, and the above clogging can be reliably removed. Convenient.
[0014]
Even if the hole 16 that communicates the bottom of the water droplet receiver 15 and the inside of the drain trap 12 is provided as described above, the drain trap 12 is disposed in the machine room 6, and therefore, the drain trap 11 extends from the drain groove 11. No odor or the like flowing into the ice 12 reaches the ice making section or ice storage chamber 2 through the drain trap 12 at all.
[0015]
In the embodiment shown in FIG. 3, the bowl-shaped water drop receiver 15 formed integrally with the drain trap 12 is relatively shallow and is arranged at a distance from the lower surface of the lower curved portion 14. Since it is not covered, there is an advantage that the same effect as the above embodiment example can be obtained, and that the state in the drain trap 12 can be easily confirmed from the outside more than the case of the above embodiment example, Since the water drop receiver 15 is relatively small, the manufacturing cost of the drain trap 12 can be further reduced.
[0016]
Further, in the embodiment shown in FIG. 4, the bowl-shaped water drop receiver 15 is integrally formed with the drain trap 12 and is spaced from the lower surface of the lower curved portion 14, while the lower portion of the drain trap 12. The trap part 20 branched from the flow path 12 ′ extends downward in the water drop receiver 15, and the lower end of the trap part 20 is immersed in the stored water 21 at the bottom of the water drop receiver 15.
[0017]
Therefore, when dew condensation water from the outside air generated on the surface of the lower curved portion 14 is dropped from the lower curved portion 14 into the stored water 21 at the bottom of the water drop receiver 15, it sequentially passes through the trap portion 20 and flows below the drain trap 12. Since it flows into 12 'and is discharged | emitted from the drain pipe 10 to the drain groove 11, it can have the same effect as said each embodiment, and the strange odor which flowed into the drain trap 12 from the drain groove 11 is shown. And the like can be reliably prevented by the trap unit 20 from reaching the machine room 6.
Condensed water from the outside air generated on the outer surface of the water drop receiver 15 flows downward along the outer surface of the drain trap lower flow path 12 ′, but at the same time the flow range of the condensed water is limited. Since it does not drop and scatter, the treatment can be easily performed.
[0018]
【The invention's effect】
In the drain trap according to the present invention, the condensed water generated on the surface of the downward curved portion can be received by the water droplet receiver provided below, and there is no need to attach a heat insulating material around the trap portion. Therefore, there is an advantage that the cost of the drain trap can be easily reduced.
