Abstract

<P>PROBLEM TO BE SOLVED: To rationally allow external noises to escape even if a control unit and a hot water storage means are only a short distance apart and adjacent to each other, thereby preventing the noises from affecting the microcomputer of the control unit or the like. <P>SOLUTION: The water heater includes a control unit 1; a microcomputer 2; a hot water heating means 3; a hot water heating means shell 4; a hot water storage means 5; a first connection means 7; a removable shield means 8; and a second connection means 9. The external noises entering from a power supply means 6 are allowed to escape from the control unit 1 through a path including the shield means 8, hot water in the hot water storage means 5, and the hot water heating means shell 4 so as to prevent the external noises from passing around the microcomputer 2. This also enables operations to be carried out during production of the control unit 1 without connecting the shield means 8 that obstructs the process of flow soldering. Thus, the influence of the external noises is avoided and productivity is increased. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明はトイレ用衛生洗浄器などに搭載される温水装置に関するものである。   The present invention relates to a hot water device mounted on a sanitary washer for toilets.

従来、この種のトイレ用衛生洗浄器などに搭載される温水装置は、制御ユニットと、温水加熱手段と、温水貯蔵手段を有し、制御ユニットで制御された温水加熱手段で加熱された温水を温水貯蔵手段に一定量貯蔵して洗浄などに使用している。   Conventionally, a hot water apparatus mounted on this type of toilet sanitary washer has a control unit, a hot water heating means, and a hot water storage means, and uses hot water heated by the hot water heating means controlled by the control unit. A certain amount is stored in hot water storage means and used for cleaning.

図９は従来の温水装置を示すもので、制御ユニット５１と、マイコン５２と、温水加熱手段５３と、温水加熱手段外郭５４と、温水貯蔵手段５５と、電源供給手段５６から構成されている（例えば、特許文献１参照）。
特開２００２−３７２３０６号公報 FIG. 9 shows a conventional hot water apparatus, which comprises a control unit 51, a microcomputer 52, a hot water heating means 53, a hot water heating means outer shell 54, a hot water storage means 55, and a power supply means 56 ( For example, see Patent Document 1).
JP 2002-372306 A

しかしながら、前記従来の構成にあって、制御ユニット５１と温水貯蔵手段５５の距離が近く隣接しているような場合には、温水貯蔵手段５５内の温水が温水加熱手段外郭５４を介してアース電位となっていることにより、電源供給手段より制御ユニット５１内に浸入した外部ノイズが、この制御ユニット５１に実装したマイコン５２の周辺から温水貯蔵手段５５内の温水及び温水加熱手段外郭５４を介して逃げる経路ができてしまう。そのため、外部ノイズの影響を受けやすいというという課題を有していた。   However, in the conventional configuration, when the distance between the control unit 51 and the hot water storage means 55 is close to each other, the hot water in the hot water storage means 55 is connected to the ground potential via the hot water heating means outer shell 54. As a result, external noise that has entered the control unit 51 from the power supply means passes from the periphery of the microcomputer 52 mounted on the control unit 51 through the hot water in the hot water storage means 55 and the hot water heating means outline 54. A route to escape is created. For this reason, there is a problem that it is easily affected by external noise.

本発明は前記従来の課題を解決するもので、制御ユニットと温水貯蔵手段の位置関係にかかわらず、外部ノイズの影響を受けにくく、かつ制御ユニットの生産性もよい温水装置を提供することを目的とする。   SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a hot water apparatus that is hardly affected by external noise and has good productivity of the control unit regardless of the positional relationship between the control unit and the hot water storage means. And

電源供給手段から浸入した外部ノイズをシールド手段を介して逃がすことにより、マイコン周辺を外部ノイズが通らないようにできる。また制御ユニットの生産時にはフローはんだ等の工程の妨げとなるシールド手段を接続しない状態で生産できるので、制御ユニットと温水貯蔵手段の位置関係にかかわらず、外部ノイズの影響を受けにくく、かつ制御ユニットの生産性もよくすることが可能となる。   By escaping external noise that has entered from the power supply means through the shield means, it is possible to prevent external noise from passing around the microcomputer. In addition, since it is possible to produce the control unit without connecting shield means that interfere with the process such as flow soldering, the control unit is not easily affected by external noise regardless of the positional relationship between the control unit and the hot water storage means. It is possible to improve the productivity.

In FIG. 1, 1 is a control unit, 2 is a microcomputer mounted on the control unit 1, 3 is hot water heating means that heats water under the control of the control unit 1, and 4 is hot water heating means 3. The hot water heating means outer shell 5 that covers the outside, is electrically insulated from the hot water heating means 3 and is grounded, and 5 includes the hot water heating means 3 and the hot water heating means outer shell 4, and is heated by the hot water heating means 3. This hot water is supplied to, for example, a toilet toilet cleaning means.

以上のように構成された温水装置について以下その動作、作用を説明する。   The operation and action of the hot water apparatus configured as described above will be described below.

まず、電源供給手段６から浸入した外部ノイズは制御ユニット１上の電源ラインを通ってシールド手段８に到達する。そして外部ノイズはシールド手段８から温水貯蔵手段５に貯蔵された温水を介して温水加熱手段外郭４に到達しアースへ逃げる。   First, external noise that has entered from the power supply means 6 reaches the shield means 8 through the power supply line on the control unit 1. Then, the external noise reaches the hot water heating means outer shell 4 from the shield means 8 via the hot water stored in the hot water storage means 5 and escapes to the ground.

このようにマイコン２周辺よりも電源側に別の経路を設けることで、マイコン２周辺を外部ノイズが通らないようにすることができる。また制御ユニット１の生産時には第一の接続手段７のみを実装し、制御ユニット１の生産後に第二の接続手段９によってシールド手段８を接続することで、フローはんだ等の工程の妨げとなるシールド手段８を接続しない状態で制御ユニット１を生産することができる。   Thus, by providing another path on the power supply side than the periphery of the microcomputer 2, it is possible to prevent external noise from passing through the periphery of the microcomputer 2. Further, only the first connecting means 7 is mounted at the time of production of the control unit 1, and the shield means 8 is connected by the second connecting means 9 after the production of the control unit 1, so that a shield that hinders a process such as flow soldering. The control unit 1 can be produced without connecting the means 8.

図８は、図７の構成にコンデンサ１０を追加したものである。すなわち、制御ユニット１上の電源ラインと接続して、この制御ユニット１にコンデンサ１０を実装したものである。   FIG. 8 is obtained by adding a capacitor 10 to the configuration of FIG. That is, the capacitor 10 is mounted on the control unit 1 connected to the power supply line on the control unit 1.

この場合は、電源供給手段６から浸入した外部ノイズが制御ユニット１上の電源ラインを通ってコンデンサ１０を介してシールド手段８に到達し、その後、温水貯蔵手段５に貯蔵された温水、温水加熱手段外郭４を介してアースへ逃げる。   In this case, external noise that has entered from the power supply means 6 passes through the power supply line on the control unit 1 and reaches the shield means 8 via the capacitor 10, and then warm water and warm water heating stored in the hot water storage means 5. Escape to ground through means outer shell 4.

このように電源供給手段６とシールド手段８の間にコンデンサ１０を設けることで、電源供給手段６とシールド手段８が電気的に絶縁され、メンテナンスなどの時に作業者がシールド手段８に触れてもより感電しにくいようにすることができる。   By providing the capacitor 10 between the power supply means 6 and the shield means 8 in this way, the power supply means 6 and the shield means 8 are electrically insulated, and even if an operator touches the shield means 8 during maintenance or the like. It can be made more difficult to get an electric shock.

コンデンサ１０は、第二の接続手段９とシールド手段８との接続中点に介在させることも考えられる。   It is also conceivable that the capacitor 10 is interposed at the midpoint of connection between the second connection means 9 and the shield means 8.

以上のように、本発明にかかる温水装置は、電源供給手段から浸入した外部ノイズを、制御ユニットからシールド手段を介して逃がし、マイコン周辺を外部ノイズが通らないようにすることにより、外部ノイズに影響を受けにくくすることが可能となるので、外部ノイズの影響を受けやすい取り付け構成となっている制御ユニットを有する機器の信頼性の向上等の用途にも適用できる。   As described above, the hot water device according to the present invention allows external noise that has entered from the power supply means to escape from the control unit through the shield means, and prevents external noise from passing around the microcomputer, thereby preventing external noise from passing through the microcomputer. Since it becomes possible to make it difficult to be influenced, it is applicable also to uses, such as an improvement in the reliability of the apparatus which has the control unit which becomes the attachment structure which is easy to be influenced by an external noise.
