Description

本発明は、水を瞬間的に温水に加熱する瞬間式加熱手段を有するトイレ装置に関するものである。   The present invention relates to a toilet apparatus having instantaneous heating means for instantaneously heating water to warm water.

従来、この種のトイレ装置は、図8に示されているようなものであった(例えば、特許文献1参照)。   Conventionally, this type of toilet apparatus has been as shown in FIG. 8 (see, for example, Patent Document 1).

図8において、熱交換器1は、貯湯ハウジング2の中に給水管3を差し込み、この給水管3と一体的に形成した電気発熱体を外表面側に埋没する中空筒状セラミック製のヒータ4を、その周りを銅等熱伝導性の良好な金属材料からなるスリーブ5により囲繞して形成した加熱タンク6を備え、この加熱タンク6は内側の流路を先端(図の右方向)に行くほど斜め下向きとした状態で、貯湯ハウジング2に水密構造となして横架・固定されている。   In FIG. 8, a heat exchanger 1 is a hollow cylindrical ceramic heater 4 in which a water supply pipe 3 is inserted into a hot water storage housing 2 and an electric heating element formed integrally with the water supply pipe 3 is buried on the outer surface side. Is provided with a heating tank 6 surrounded by a sleeve 5 made of a metal material having good thermal conductivity such as copper, and this heating tank 6 goes through the inner channel toward the tip (right direction in the figure). The water storage housing 2 is horizontally mounted and fixed in a state of being inclined downward so as to have a watertight structure.

そして、前記貯湯ハウジング2内の加熱タンク6上部の空所を貯湯部7となして、その一部に空焚き防止用のフロートスイッチ8が、洗浄水の流通を妨げない適切な位置で組込まれている。ヒータ4の基端(図の左方向)には、貯湯ハウジング2壁面に設けた膨出部aに、ハウジング2の上端面から縦方向に通抜孔9を穿孔し、この通抜孔9を介して加熱タンク6と貯湯ハウジング2の貯湯部7とを連通させる。   A space above the heating tank 6 in the hot water storage housing 2 is used as a hot water storage portion 7, and a float switch 8 for preventing emptying is incorporated in a part of the hot water storage portion 2 at an appropriate position that does not hinder the flow of cleaning water. ing. At the base end (left direction in the figure) of the heater 4, a through hole 9 is formed in the bulging portion a provided on the wall surface of the hot water storage housing 2 in the vertical direction from the upper end surface of the housing 2. The heating tank 6 and the hot water storage section 7 of the hot water storage housing 2 are communicated with each other.

そして、前記通抜孔9の加熱タンク6内に臨む下部開口部bには、貯湯ハウジング2の壁面に前記開口部bの断面積の約半分を遮る状態で、邪魔板10が、ハウジング2の壁面と一体となって加熱タンク6内に水平に形成されている。また、前記通抜孔9の貯湯ハウジング2内に位置する上部には、貯湯部7と連通する開口部cが開口されており、前記上下部に開口部b、cを有する通抜孔9内には、貯湯ハウジング2の上部に取付けた温度センサ11の検温部11aが、下部開口部bから加熱タンク6内に突出しない範囲で挿入されている。また、貯湯ハウジング2の上部中央に加熱防止用のバイメタルスイッチ12が取付けられている。次に動作について説明する。不使用時は、熱交換器1内に適温に保温された洗浄水が貯湯部7および加熱タンク6内に貯留されている。この状態で、使用時は、水が熱交換器1に流入すると同時にヒータ4はフル通電を開始する。   In the lower opening b facing the heating tank 6 of the through-hole 9, the baffle plate 10 is placed on the wall surface of the housing 2 with the wall surface of the hot water storage housing 2 blocking about half of the cross-sectional area of the opening b. And is formed horizontally in the heating tank 6. Further, an opening c communicating with the hot water storage section 7 is opened at an upper portion of the through hole 9 located in the hot water storage housing 2, and in the through hole 9 having the openings b and c at the upper and lower portions. The temperature detecting portion 11a of the temperature sensor 11 attached to the upper part of the hot water storage housing 2 is inserted in a range that does not protrude into the heating tank 6 from the lower opening b. A bimetal switch 12 for preventing heating is attached to the upper center of the hot water storage housing 2. Next, the operation will be described. When not in use, the washing water kept at an appropriate temperature in the heat exchanger 1 is stored in the hot water storage section 7 and the heating tank 6. In this state, at the time of use, water flows into the heat exchanger 1 and the heater 4 starts full energization.

そして、水はヒータ4の内側から該ヒータ4の外表面とスリーブ5との間を流れている間に、ヒータ4により加熱されて貯湯部7に流入する。一方、熱交換器1内に保温されていた温水は、給水管3から流入する洗浄水により貯湯ハウジング2から順次押し出される。このように、局部洗浄に際して洗浄水が給水管3を通って熱交換器1内に流入すると、洗浄水はヒータ4により加熱されて温水となる。そして、温水の温度は、加熱タンク6と貯湯部7とを連通させる通抜孔9内に検温部11aを挿入した温度センサ11により検出し、検出温度が事前に設定した温度に対して高、低差がある場合は、制御装置からの指令によりヒータ4を通電(オン・オフ)制御させてあらかじめの設定した所定温度に維持させる。然るに、冷水を熱交換器1により適温水に加熱して給送している場合、給水管3から流入する洗浄水によって加熱タンク6内で、ヒータ4の加熱作用をあまり受けることなく滞留している低温水が、通抜孔9側に押し出されたとき、前記低温水は通抜孔9の方向に直上的に上昇する。   While the water flows between the outer surface of the heater 4 and the sleeve 5 from the inside of the heater 4, the water is heated by the heater 4 and flows into the hot water storage section 7. On the other hand, the hot water kept in the heat exchanger 1 is sequentially pushed out from the hot water storage housing 2 by the wash water flowing from the water supply pipe 3. In this way, when the cleaning water flows into the heat exchanger 1 through the water supply pipe 3 during the local cleaning, the cleaning water is heated by the heater 4 to become warm water. The temperature of the hot water is detected by a temperature sensor 11 in which a temperature detecting portion 11a is inserted into a through hole 9 that allows the heating tank 6 and the hot water storage portion 7 to communicate with each other, and the detected temperature is higher or lower than the preset temperature. If there is a difference, the heater 4 is energized (on / off) in accordance with a command from the control device and maintained at a predetermined temperature set in advance. However, when the cold water is heated and supplied to the appropriate temperature water by the heat exchanger 1, the water stays in the heating tank 6 without receiving the heating action of the heater 4 by the washing water flowing in from the water supply pipe 3. When the low temperature water is pushed out to the through hole 9 side, the low temperature water rises directly upward in the direction of the through hole 9.

ところが、通抜孔9の下部開口部bは、加熱タンク6内において水平に突設した邪魔板10により約半分程の面積が遮られているので、前記低温水は邪魔板10に沿って水平方向(加熱タンク6の先端側)に移動し、前記通抜孔9の下部開口部bの手前側でヒータ4により加熱されて通抜孔9側に流通する温水と接衝して混合する。そして、前記混合された洗浄水は、そのまま、通抜孔9の下部開口部bから上部開口部cを通って貯湯部7に押し出される。この際、水はヒータ4により加熱された洗浄水と大部分が混合されるため、この混合された温水は、通抜孔9内を通過する際、温度センサ11の検温部11aにて温度検出が行われるものの、その検出温度は低温水でなく、混合を行った温水で行われるため、前記検出温度は設定温度に近い温度を検出することが可能となっていた。
特許第3325874号公報
However, since the lower opening b of the through hole 9 is blocked about half of the area by the baffle plate 10 that protrudes horizontally in the heating tank 6, the low-temperature water flows horizontally along the baffle plate 10. It moves to (the front end side of the heating tank 6) and mixes in contact with the hot water heated by the heater 4 on the front side of the lower opening b of the through hole 9 and flowing to the through hole 9 side. The mixed washing water is pushed out from the lower opening b of the through hole 9 to the hot water storage section 7 through the upper opening c. At this time, since most of the water is mixed with the washing water heated by the heater 4, the temperature of the mixed warm water is detected by the temperature detection unit 11 a of the temperature sensor 11 when passing through the through-hole 9. Although it is performed, the detected temperature is not low temperature water but mixed water, so that the detected temperature can detect a temperature close to the set temperature.
Japanese Patent No. 3325874

しかしながら、前記従来のトイレ装置では、ヒータ4を内蔵した加熱タンク6の上部に、加熱防止用のバイメタルスイッチ12を内蔵した貯湯部7を配設しているために、使用時・非使用時にかかわらずバイメタルスイッチ12に常に保温時の温度以上の雰囲気で使用する必要があり、バイメタルスイッチ12のOFF設定温度を高く設定しなければならないという課題があった。   However, in the conventional toilet device, the hot water storage section 7 with the bimetal switch 12 for preventing heating is disposed above the heating tank 6 with the heater 4 built-in. Therefore, it is necessary to always use the bimetal switch 12 in an atmosphere higher than the temperature at the time of heat retention, and there is a problem that the OFF set temperature of the bimetal switch 12 must be set high.

この場合、ケースの同一面側に加熱部と温度検知部の部品を搭載するようにしたので、温度検知部の部品である温度センサとサーモスイッチとをケースの一方向から組付けられることから組立性を改善することができ、加熱水路の下流の温度を検知する温度センサとサーモスイッチとを、平板状ヒータの平板状表面と対向するケースの同一面側から組付け加熱部の近傍に配し、温度検知部に搭載されたサーモスイッチの感温部への水路構成は、感温部の下方向から入水し、上方向から出水するようにしたので、感温部での空気溜りの発生を避けることにより、サーモスイッチの感度を低下させることなく反応させることができる。  In this case, since the parts of the heating part and the temperature detection part are mounted on the same surface side of the case, the temperature sensor and the thermo switch, which are parts of the temperature detection part, can be assembled from one direction of the case. The temperature sensor that detects the temperature downstream of the heating channel and the thermo switch are arranged near the assembly heating unit from the same side of the case facing the flat plate surface of the flat plate heater.

The outlet of the check valve 13 is connected to a water stop electromagnetic valve 16 through a constant flow valve 15. The outlet of the water stop solenoid valve 16 is connected to the inlet of a water pump 19 driven by a pump motor 18 via a vacuum breaker valve 17. The vacuum breaker valve 17 is configured to introduce air when the inlet side of the water pump 19 becomes negative pressure, and is configured to branch and discharge overflow water to the water tank. The outlet of the water pump 19 is connected to the inlet 21a of the instantaneous heating means 21 through the flow rate sensor 20, and the pump motor 18 is driven and controlled by the flow rate detected by the flow rate sensor 20, so that the washing water at a constant flow rate can be instantaneously supplied with high accuracy. It is comprised so that it may feed to the type | formula heating means 21. FIG. A water supply means 22 is constituted by the flow rate sensor 20 from the check valve 13.

A temperature sensor 11 for detecting the temperature of the hot water and a safety thermo switch 25 are provided. And it is comprised so that the hot water of predetermined temperature may be obtained by performing electricity supply control with respect to the heater 4 according to the detection signal of the temperature sensor 11. FIG. Further, in order to prevent abnormal heating of the heater 4, a safety device (thermal fuse) 26 (see FIG. 4) described later is provided. Hot water delivered from the outlet 21 b of the instantaneous heating means 21 is jetted locally by the nozzle means 27.

次に、瞬間式加熱手段21の詳細構成を説明する。瞬間式加熱手段21は、加熱水路24を有する加熱部28と、温度センサ11およびサーモスイッチ25を有する温度検知部29を略同一平面上に配して一体に構成されている。   Next, the detailed configuration of the instantaneous heating means 21 will be described. The instantaneous heating means 21 is configured integrally with a heating unit 28 having a heating water channel 24 and a temperature detection unit 29 having a temperature sensor 11 and a thermo switch 25 arranged on substantially the same plane.

次に、安全制御構成を図3にて説明する。電源30に対して温水噴出スイッチおよびヒータ4に対する通電と連動するトライアック31と止水電磁弁16と安全装置(温度ヒューズ)26とサーモスイッチ25が直列に接続されており、安全装置(温度ヒューズ)26とサーモスイッチ25の何れが絶たれても止水電磁弁16に対する通電が停止して直ちに給水が停止されるように構成されている。更に、止水電磁弁16の両端電圧を検出する検出手段32が設けられ、その検出信号によってポンプモータ18に対して通電制御するトランジスタ33がONし、両端電圧がなくなるとトランジスタ33がOFFし、従って止水電磁弁16が開くとポンプモータ18が駆動され、閉じるとポンプモータ18も同時に停止するように構成されている。   Next, the safety control configuration will be described with reference to FIG.

Even if either of the switch 26 and the thermo switch 25 is cut off, the power supply to the water stop solenoid valve 16 is stopped and the water supply is immediately stopped. Further, a detecting means 32 for detecting the voltage across the water stop solenoid valve 16 is provided, and the transistor 33 for controlling the energization of the pump motor 18 is turned on by the detection signal. When the voltage across the pump is lost, the transistor 33 is turned off. Accordingly, the pump motor 18 is driven when the water stop electromagnetic valve 16 is opened, and the pump motor 18 is also stopped simultaneously when the water stop electromagnetic valve 16 is closed.

以上のように構成されたトイレ装置について、以下その動作、作用を説明する。   About the toilet apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

温水噴出スイッチがONされると、止水電磁弁16が開くとともに水ポンプ19が作動して瞬間式加熱手段21に洗浄水が送給され、瞬間式加熱手段21で温度センサ11による検出温度に応じて通電制御されるヒータ4にて洗浄水が所定温度に加温され、ノズル手段27から局部に噴出される。また、異常加熱時に温度センサ11が働かない場合は、安全装置(温度ヒューズ)26とサーモスイッチ25の何れが絶たれても止水電磁弁16に対する通電が停止して直ちに給水が停止するようになっている。   When the hot water ejection switch is turned on, the water stop solenoid valve 16 is opened and the water pump 19 is operated to supply cleaning water to the instantaneous heating means 21, and the instantaneous heating means 21 sets the temperature detected by the temperature sensor 11. Accordingly, the washing water is heated to a predetermined temperature by the heater 4 that is energized and is ejected from the nozzle means 27 to the local portion. Also, if the temperature sensor 11 does not work during abnormal heating, power supply to the water stop solenoid valve 16 stops and water supply stops immediately regardless of which of the safety device (temperature fuse) 26 and the thermo switch 25 is cut off. It has become.

以上のように、本実施の形態においては、非使用時の温度検知部29の雰囲気温度を低下させることにより、温度変化への対応がよくなり、異常加熱時の安全装置(温度ヒューズ)26とサーモスイッチ25のOFF設定温度を低く設定させ、異常加熱時の感度を良くすることができる。   As described above, in the present embodiment, by reducing the ambient temperature of the temperature detection unit 29 when not in use, it is possible to cope with temperature changes, and the safety device (temperature fuse) 26 during abnormal heating The OFF set temperature of the thermo switch 25 can be set low, and the sensitivity during abnormal heating can be improved.

本実施の形態において、実施の形態1の構成と異なるところは、温度検知部29は、加熱部28の近傍に配したところである。なお、実施の形態1と同一符号のものは同一構造を有し、説明は省略する。   In the present embodiment, the difference from the configuration of the first embodiment is that the temperature detection unit 29 is arranged in the vicinity of the heating unit 28. In addition, the thing of the same code | symbol as Embodiment 1 has the same structure, and abbreviate | omits description.

図に示すように、ケース23内に設けた水が流通する蛇行した加熱水路24を有する加熱部28から、温度センサ11およびサーモスイッチ25を有する温度検知部29へ瞬時に温水が流れるようになっている。   As shown in the figure, hot water instantaneously flows from a heating unit 28 having a meandering heating water channel 24 through which water is provided in a case 23 to a temperature detection unit 29 having a temperature sensor 11 and a thermo switch 25. ing.

以上のように構成することにより、加熱部28が異常加熱時に高温水を温度検知部29に直ぐに伝えることにより、高温水の温度を低下させることなく温度検知部29に熱を伝達させ、異常加熱時の感知時間を短縮することができる。   By configuring as described above, the heating unit 28 immediately transmits the high temperature water to the temperature detection unit 29 at the time of abnormal heating, thereby transferring the heat to the temperature detection unit 29 without reducing the temperature of the high temperature water, thereby causing abnormal heating.
