Abstract

<P>PROBLEM TO BE SOLVED: To stably operate a heat exchanger over a long period by preventing frost formation on the heat exchanger by efficiently utilizing ultrasonic vibration. <P>SOLUTION: Piping 3 is vibrated by mounting an ultrasonic vibrator to atomize and release water droplets generated when moisture in the air is liquefied following cooling. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は冷蔵庫等に用いられる熱交換器の着霜防止に関する。  The present invention relates to prevention of frost formation on a heat exchanger used in a refrigerator or the like.

通常熱交換器は低温使用時には空気中の水分が表面に付着、氷結し極端に効率が低下するため運転停止を伴う徐霜が不可欠であった。  Usually, when heat exchangers are used at low temperatures, moisture in the air adheres to the surface and freezes, resulting in extremely low efficiency.

従来より熱交換器の除霜装置としては、例えば特開平６−２６５２９１号公報に開示されるように、超音波振動を用いて熱交換器に付着した氷霜を取り除く物が知られている。しかしながらそれらは複雑な構造を構成しコストも高くつくにもかかわらず効率の低いもので全く実用化されていなかった。  2. Description of the Related Art Conventionally, as a defroster for a heat exchanger, as disclosed in, for example, Japanese Patent Application Laid-Open No. 6-265291, an object that removes ice frost attached to a heat exchanger using ultrasonic vibration is known. However, they have a complicated structure and cost is high, but they have low efficiency and have not been put into practical use at all.

本発明はこのような問題点を解決するためになされたもので超音波振動を効率よく利用し、熱交換器への着霜を防止し長期間の安定した運転を可能にするものである。The present invention has been made to solve such problems, and efficiently utilizes ultrasonic vibration to prevent frost formation on the heat exchanger and enable stable operation for a long period of time.

上述の目的を達成する本発明の熱交換器は超音波振動子が直接固定され、かつその熱交換器全体をフローティングマウントとすることを特徴とする。
本発明では熱交換器を超音波振動子と適当な寸法の金属プレートで挟む構造として振動を効率よく伝える。又その振動の減衰を最小限にし、他の部分に悪影響を及ぼすことを防止するため熱交換器の取り付け、および冷媒の配管を弾性部材を介して行うものとする。The heat exchanger of the present invention that achieves the above object is characterized in that the ultrasonic vibrator is directly fixed and the whole heat exchanger is a floating mount.
In the present invention, vibration is efficiently transmitted as a structure in which the heat exchanger is sandwiched between an ultrasonic vibrator and a metal plate having an appropriate size. Further, in order to minimize the damping of the vibration and prevent other parts from being adversely affected, the heat exchanger is attached and the refrigerant piping is performed through an elastic member.

以上説明したように本発明によれば、超音波振動を熱交換器のみに伝え低温運転時の着霜を効率よく防止できるので従来の技術では不可欠であった運転停止を伴う除霜が基本的に不要となり長期間の安定した温度管理が可能となる。  As described above, according to the present invention, ultrasonic vibration is transmitted only to the heat exchanger, so that frost formation during low temperature operation can be efficiently prevented. It becomes unnecessary, and stable temperature control for a long time becomes possible.

本発明は例えば冷蔵装置等に応用すれば食品の鮮度維持やその他の物の品質保持に有効である。また医療、科学分野においても長期にわたる環境試験やサンプル保存に有効である。  The present invention is effective for maintaining the freshness of food and maintaining the quality of other items when applied to, for example, a refrigerator. It is also effective for long-term environmental tests and sample storage in the medical and scientific fields.

また、ヒートポンプ式による暖房をおこなう際にも徐霜のための運転停止およびヒーターによる加熱が不要となり消費電力を低下させることが出来るものである。  In addition, when heating by a heat pump method, operation stop for slow frost and heating by a heater are unnecessary, and power consumption can be reduced.

以下、本発明の実施例を図面に基づいて説明する。  Embodiments of the present invention will be described below with reference to the drawings.

図１〜図３は本発明の実施の形態に係り、図１はその外観斜視図、図２はその中央、振動子取り付け部の縦断面図、図３は熱交換器の取り付け部の縦断面図である。  1 to 3 relate to an embodiment of the present invention, FIG. 1 is an external perspective view thereof, FIG. 2 is its center, a longitudinal sectional view of a vibrator mounting portion, and FIG. 3 is a longitudinal sectional view of a mounting portion of a heat exchanger. FIG.

図１で示すように本熱交換器１はその中央部に超音波振動子２を取り付けたものである。  As shown in FIG. 1, the present heat exchanger 1 has an ultrasonic vibrator 2 attached to the center thereof.

図２に示すように冷媒を流通する配管３は中心部に雌螺旋きり加工された振動子２と金属プレート７によって挟まれ両者は固定用ボルト８によって確実に密着する。  As shown in FIG. 2, the pipe 3 through which the refrigerant flows is sandwiched between the vibrator 2 and the metal plate 7 that are cut into a female spiral at the center, and the two are securely adhered by the fixing bolts 8.

配管３は例えばシリコーンゴムのような弾性素材を用いたチューブ４を介して冷媒を流通させるのでその振動を冷凍機等他の部分に伝播させず、又振動による接続部の緩みやクラックによる冷媒の漏れを防ぐことが出来る。  The pipe 3 circulates the refrigerant through the tube 4 made of an elastic material such as silicone rubber, so that the vibration is not propagated to other parts such as a refrigerator, and the refrigerant is loosened due to the loosening or cracking of the connection part. Leakage can be prevented.

熱交換器１を支える取付金具５は図３に示すように弾性素材のリング９によって振動を吸収されボルト１２、ナット１３により壁面６に取り付けられる。  As shown in FIG. 3, the mounting bracket 5 that supports the heat exchanger 1 is absorbed by the elastic ring 9 and attached to the wall surface 6 by bolts 12 and nuts 13.

以上の構成により本熱交換器１は支持壁面６および冷媒の流通系統に悪影響を及ぼす超音波振動を伝えることなく効率よく作動し、冷却によって生じた水滴を霧化して発散させることにより所期の目的を達成するものである。  With the above configuration, the heat exchanger 1 operates efficiently without transmitting ultrasonic vibrations that adversely affect the support wall surface 6 and the refrigerant distribution system, and the desired water droplets generated by cooling are atomized to diverge. It achieves its purpose.
