Description

【０００１】
【発明の属する技術分野】
本発明は、冷蔵庫における機械室内の圧縮機の上方に配設される蒸発皿に関するものである。
【０００２】
【従来の技術】
近年の冷蔵庫は、内容積効率の向上を図り広い庫内空間を有するとともに、合理化を図った製品の開発が盛んに進められている。
【０００３】
従来の冷蔵庫のなかには、特開平９−１１３１１４号公報に開示されているものがある。
【０００４】
以下、図面を参照しながら上記従来の冷蔵庫を説明する。
図５は従来の冷蔵庫の機械室の要部背面図、図６は同冷蔵庫の蒸発皿の要部断面斜視図である。
【０００５】
図において、機械室５１には圧縮機５２，凝縮器５３を収納しており、圧縮機５２から凝縮器５３、キャピラリチューブ５４を経て、庫内に配置した冷却器に至り、配管パイプ５５により圧縮機５２まで閉回路を形成し、冷媒を循環して冷凍サイクルを構成している。
【０００６】
また、ファン５６と電動機５７にて機械室５１内に対流を起こし、矢印で示すように冷蔵庫前面から外気を吸い込み、凝縮器５３の凝縮能力を向上させるとともに、圧縮機５２を冷却させるようになっていたものである。５８は電動機５７を取り付ける仕切り板であり、電動機５７にて風を生成する際の高低圧を起こすための間仕切りを兼ねている。仕切り板５８の外周にはフォーム材５９を巻き付けて、底板６０との隙間をシールしている。
【０００７】
また、蒸発皿６１は圧縮機５２の上方に配設し、圧縮機５２の熱にて蒸発皿６１内に貯留する除霜水を蒸発させる構成となっている。蒸発皿６１の外形を小さくし、機械室５１の空間をコンパクトにすることが図られている。このため、蒸発皿６１の底の形状は、貯水効率を上げ、かつ圧縮機５２の熱を受熱し易いように圧縮機５２の上部の外形に沿うように凸状部６１ａが形成されていた。そして、蒸発皿６１の下端には冷蔵庫を移動する場合等に蒸発皿６１内の水を排出するための排水口６１ｂを形成し、その先にはシール用パッキン６２を取り付けた排水栓６３を設けている。
【０００８】
【発明が解決しようとする課題】
上記従来の構成では、蒸発皿６１は圧縮機５２の上方に配設されていて、圧縮機５２の熱にて蒸発皿６１内の除霜水を蒸発させる構成であるため、蒸発皿６１の底の形状は、圧縮機５２の上部の外形に沿うように凸状部６１ａが形成されていて、除霜水は蒸発皿６１の凸状部６１ａに隣接している谷部６１ｃの底に溜まる。そして、蒸発皿６１内の温度は圧縮機５２の真上に位置する凸状部６１ａの部分が最も強く圧縮機５２の熱を受け、除霜水の溜まり易い谷部６１ｃは蒸発速度が遅くなり、汚れ等の付着部で悪臭を発生するという欠点があった。
【０００９】
本発明は従来の課題を解決するもので、蒸発速度を早めた蒸発皿とすることを目的とする。
【００１０】
【課題を解決するための手段】
この目的を達成するために本発明は、圧縮機の上方に配設した蒸発皿内に、圧縮機の山状になった頂部に沿うような形に形成された底面の凸状部と、前記凸状部の外周であって圧縮機の山状の頂部から外周に外れて位置する谷部との間に区画壁を設けて、第１貯水部と第２貯水部とを構成し、冷却器からの水は前記する区画壁で区画された中央部の第１貯水部に貯水され、第１貯水部から溢れ出た水が前記する区画壁外周に形成される第２貯水部に貯水されるようにしたものである。従って、圧縮機の熱を受熱し易い第１貯水部の貯水深さを深くし、蒸発がし難い第２貯水部には貯水深さを第１貯水部より浅くして、第１貯水部ならびに第２貯水部からの蒸発をし易くし、蒸発皿の底部に付着物が付着して悪臭を発生するような問題点をなくしたものである。また、内周に栓体ネジ部を有し、前記栓体ネジ部の内側に形成した円状のリブを形成した排水栓の前記栓体ネジ部を螺合する排水口ネジ部と、前記円状のリブの基部および前記栓体ネジ部の下端に当接する前記排水口ネジ部の先端に形成されていて可撓性を有するクッション部とを備えた排水口を前記第１貯水部または前記第２貯水部の下端に具備したものである。従って、蒸発皿内の残水を排出口から容易に排水できるようにするとともに、排水栓からの水洩れが発生するような問題点をなくしたものである。
【００１１】
【発明の実施の形態】
本発明は、圧縮機の上方に配設し、圧縮機の頂部に沿うような形の底部を有する蒸発皿に区画壁を形成し、第１貯水部と第２貯水部を形成し、冷却器からの除霜水を蒸発皿の第１貯水部に流し込み、第１貯水部より溢れ出た水は第２貯水部に貯水されるようにする。そして、前記区画壁は圧縮機の山状になった頂部に沿って凸状部となっていて、圧縮機の熱を最も受け易い部分と、圧縮機の山状の頂部から外周に外れて位置する谷部との間に設ける。従って、蒸発皿中央の第１貯水部の貯水深さは、深くても圧縮機の熱を受けて蒸発する。また、第２貯水部の貯水深さは、第１貯水部の貯水深さよりも浅くなり、圧縮機の熱を受熱し難い第２貯水部であっても、蒸発が早いことになる。以上の機能を果すように蒸発皿を構成することによって、本発明は実施できるものである。
【００１２】
また、第２貯水部に排水栓を設けることにより、冷蔵庫を移動する場合等に第２貯水部の貯水を排水することができる。そして、この排水構造も特殊なシール構造にして実施することにより、シール性能のよいものとすることができる。そこで、以下には本発明の実施形態における具体構成を実施例として詳細に説明する。
【００１３】
【実施例】
以下、本発明による冷蔵庫の蒸発皿の実施例について、図面を参照しながら説明する。
【００１４】
図１は本発明の実施例における冷蔵庫の機械室の要部斜視図、図２は同実施例における冷蔵庫の蒸発皿の斜視図、図３は同実施例における冷蔵庫の蒸発皿の断面図、図４は同実施例における冷蔵庫の蒸発皿の栓部分の断面図である。
【００１５】
図において、１は冷蔵庫背面下部の機械室であり、冷蔵庫の底板２と圧縮機の台座３で構成される。４は機械室１に収納され、台座３に載置された圧縮機である。冷媒は圧縮機４，機械室１に収納される背面凝縮器、断熱材中に配設した前面凝縮器を経て、断熱材中に配設したキャピラリチューブ、冷蔵庫の庫内に配置した冷却器、断熱材中に一端を配設した戻りパイプ５の順に循環する。
【００１６】
６は圧縮機４の上方に配設した蒸発皿であり、圧縮機４と対抗した位置に区画壁７を形成し、第１貯水部８と区画壁７の外周に第２貯水部９を形成している。庫内からの排水出口１０は蒸発皿６の第１貯水部８上に設けており、冷却器からの除霜水は第１貯水部８に溜まる。また、区画壁７の高さは蒸発皿６の外周高さより低くしている。
【００１７】
また、蒸発皿６の下端に設けた排水口１１は、略凸状で外側に排水口ネジ部１２と、排水口ネジ部１２の先端に薄膜でカール形状のクッション部１３を設けている。排水口１１の先端には、略凹状で内周に設けた栓体ネジ部１４と、栓体ネジ部１４の内側に設けた円状のリブ１５を有する排水栓１６を設けており、排水口１１の内周と排水栓１６の円状のリブ１５の外周を嵌合当接させている。
【００１８】
以上のように本実施例では、圧縮機４の頂部の温度の高い山状部分に対抗する蒸発皿６の第１貯水部８に除霜水を溜めるため、蒸発速度を早くすることができる。しかも第１貯水部８から溢れ出た水は、第２貯水部９に溜まるが、第２貯水部９での貯水頻度を少なくすることができ、汚れによる悪臭の低下を図ることができる蒸発皿６とすることができる。
【００１９】
また、蒸発皿６の下端に設け略凸状で、外側に排水口ネジ部１２と、排水口ネジ部１２の先端に薄膜で可撓性を有するカール形状のクッション部１３を設けた排水口１１と、略凹状で、内周に設けた栓体ネジ部１４と、栓体ネジ部１４の内側に設けた円状のリブ１５を有する排水栓１６からなり、排水口１１の内周と排水栓１６の円状のリブ１５の外周を嵌合当接させたものである。
【００２０】
これにより、排水口１１の内周と排水栓１６の円状のリブ１５の外周との接触によるシール部と、排水口１１の先端の薄膜でカール形状のクッション部１３と排水栓１６の底との接触によるシール部と、排水口１１の先端の薄膜でカール形状のクッション部１３と排水栓１６の栓体ネジ部１４の下端との接触によるシール部と、排水口１１の排水口ネジ部１２と排水栓１６の栓体ネジ部１４との接触によるシール部の四重シールを構成し、蒸発皿内の貯水が漏出しない安価な蒸発皿を提供することができる。
【００２１】
【発明の効果】
以上説明したように、請求項１記載の発明によれば、圧縮機の上方に配設した蒸発皿内に、圧縮機の頂部の山形状部と対抗した位置に区画壁を設けて、第１貯水部と第２貯水部を形成し、冷却器からの除霜水を蒸発皿の第１貯水部に流し込み、第２貯水部には第１貯水部より溢れ出た水を貯水することにより、蒸発速度を早めた蒸発皿とすることができる。
【００２２】
また、蒸発皿の下端に設け略凸状で外側に排水口ネジ部と、ネジ部先端に薄膜でカール形状のクッション部を設けた排水口と、略凹状で、内周に設けた栓体ネジ部と、栓体ネジ部の内側に設けた円状のリブを有する排水栓を排水口の内周と排水栓の円状のリブ外周を嵌合当接させることにより、漏水することがないシール性能のよい蒸発皿とすることができる。

A closed circuit is formed up to the machine 52, and a refrigerant is circulated to constitute a refrigeration cycle.
[0006]
Further, convection is caused in the machine room 51 by the fan 56 and the electric motor 57, and outside air is sucked in from the front of the refrigerator as indicated by an arrow to improve the condensing capacity of the condenser 53 and cool the compressor 52. It was what it was. Reference numeral 58 denotes a partition plate to which the electric motor 57 is attached, and also serves as a partition for generating high and low pressure when the electric motor 57 generates wind. A foam material 59 is wound around the outer periphery of the partition plate 58 to seal the gap with the bottom plate 60.
[0007]
The evaporating dish 61 is disposed above the compressor 52 and is configured to evaporate defrost water stored in the evaporating dish 61 by the heat of the compressor 52. An attempt is made to reduce the outer shape of the evaporating dish 61 and make the space of the machine room 51 compact. For this reason, the convex part 61a was formed so that the shape of the bottom of the evaporating dish 61 may follow the external shape of the upper part of the compressor 52 so that water storage efficiency may be improved and the heat of the compressor 52 may be received easily.

[0008]
[Problems to be solved by the invention]
In the above conventional configuration, the evaporating dish 61 is disposed above the compressor 52 and evaporates the defrosted water in the evaporating dish 61 by the heat of the compressor 52. The convex part 61a is formed so that the shape of may follow the external shape of the upper part of the compressor 52, and defrost water collects in the bottom of the trough part 61c adjacent to the convex part 61a of the evaporating dish 61. FIG. And the temperature in the evaporating dish 61 is the strongest at the portion of the convex portion 61a located directly above the compressor 52, and the heat of the compressor 52 is received, and the trough portion 61c where the defrost water tends to accumulate has a low evaporation rate. In addition, there is a drawback that a bad odor is generated at an adhesion portion such as dirt.

It is what I did. Therefore, the water storage depth of the first water storage section that is likely to receive the heat of the compressor is increased, and the water storage depth is shallower than that of the first water storage section in the second water storage section that is difficult to evaporate. This makes it easier to evaporate from the second water storage section, and eliminates the problem that an adhering substance adheres to the bottom of the evaporating dish and generates a bad odor. Also, a drain screw portion for screwing the plug screw portion of the drain plug having a plug screw portion on the inner periphery and forming a circular rib formed inside the plug screw portion, and the circle The drainage port provided with the flexible cushion part formed in the front-end | tip of the said drainage port screw | thread part which contact | abuts the base part of a shape-like rib and the lower end of the said plug body screw | thread part is said 1st water storage part or said 1st 2 is provided at the lower end of the water reservoir. Therefore, the residual water in the evaporating dish can be easily drained from the discharge port, and the problem that water leakage from the drain plug occurs is eliminated.
