Description

【0001】
【発明の属する技術分野】
本発明は、トイレ装置に関し、特に冷房機能を備えたトイレ装置に関するものである。
【0002】
【従来の技術】
トイレ部屋内を冷房する装置としては、ロータンク内に凝縮器を配置しているものがある(例えば、特許文献1参照)。
【0003】
トイレ部屋内を冷房する装置として図2に示すような冷房装置付きトイレ装置(一部透視の概略構成図である)がある。
【0004】
図2において、1はケースで、その中に、便器洗浄を行うための洗浄水を貯水するロータンク2と、冷房装置として圧縮機3、凝縮器4、減圧手段5、蒸発器6、送風機7が内蔵されている。ケース1には吹出口8が開口している。9は便器である。
【0005】
次に動作、作用について説明する。圧縮機3によって圧縮された冷媒は高温高圧の気体となり、凝縮器4に送り込まれる。凝縮器4では冷媒はロータンク2に満たされた水に凝縮熱を放熱して高圧のまま凝縮し液体となる。その後、冷媒は減圧手段5によって減圧され、蒸発器6によって蒸発気化する。この時、蒸発器6には送風機7によって風が通り、風は気化熱により冷やされた後に吹出口8から吹き出る。蒸発気化した冷媒は再び圧縮機3に戻って圧縮され、これを繰り返して冷凍サイクルが形成される。この様にして、トイレ装置から冷風を出し、冷房を行うことができる。ルームエアコンの室外機のような熱気を出すこともなく、また、冷風発生と凝縮熱の放熱がトイレ装置のケース内に収まり、コンパクトな冷房装置付きトイレ装置を構成することができる。

【0007】
【発明が解決しようとする課題】
しかしながら、前記従来の冷房装置付きトイレ装置では、凝縮器4で発生する凝縮熱はロータンク2内の水に放熱されるため、長時間冷凍サイクルが運転されるとロータンク2内の水の温度が上昇し凝縮器4での熱交換効率が落ちる。そこで熱交換率を維持するためにロータンク2内の水を一定時間毎に排水し、新たな冷水を供給していた。従って加熱された有益な湯を無駄に捨てていた。近年資源の有効活用が求められており、排水されるお湯の有効活用が必要であった。
【0008】
本発明は、前記従来の課題を解決するもので、排水されるお湯の有効活用が出来る構成とした冷房装置付きトイレ装置を提供することを目的とする。
【0009】
【課題を解決するための手段】
前記従来の課題を解決するために、本発明の冷房装置付きトイレ装置は、凝縮器の熱により水を昇温し浴槽に供給する構成としたものである。これによって、お湯を無駄に捨てることなく、凝縮器の凝縮熱で昇温されたお湯を浴槽の湯として有効に使用でき省資源、省エネルギーが達成できる。また冷房装置付きトイレ装置の設置されるトイレも浴槽のある浴室も水周りの設備なので屋内の中で隣接してほとんど位置しており(ユニットバスは同じ室内にある)冷房装置付きトイレ装置の凝縮熱で浴槽内に供給される水を温める構成は、屋内のそれぞれの位置関係を考慮した場合無理のない合理的な組み合わせと考えられる。
【0010】
【発明の実施の形態】
請求項1に記載の発明は、冷凍サイクルを構成する圧縮機、凝縮器、蒸発器と、送風機と、蒸発器と送風機から発生する冷風をトイレ室内に吹出す構成において、前記凝縮器をロータンク内に配置し、ロータンクの湯を浴槽に貯湯する構成としたので従来排水されていたお湯を有効に活用できる。
【0011】
請求項2に記載の発明は、ロータンク内に水温センサーを設け、ロータンク内の水が所定の温度に上昇した後、ロータンクの湯を浴槽に貯湯する構成としたので、常に入浴に適した湯温の湯が得られ、追い炊きの必要がなく更に省エネが図れる。
【0012】
請求項3に記載の発明は、水温センサーを凝縮器より高い位置に設けた構成としたので、浴槽への排水により水温センサーより水位が下がると水温センサーが空気に触れ、水温センサーの温度が下がることで給水を開始する構成にしたので、水がなくなり凝縮器が水より露出し熱交換ができなくなり冷凍サイクルが維持されなくなることがない。
【0013】
【実施例】
以下、本発明の実施例について図面を用いて説明する。
【0014】
(実施例1)
図1は本発明の実施例1の冷房装置付きトイレ装置の冷凍サイクルと浴槽へのお湯の供給方法の概略図である。従来例と同じ機能の部品には、同じ符号が付与してあり、説明を省略してある。
【0015】
図1において、10はロータンク内の水、11は水10の水温を感知する水温センサー、12は浴槽、13はロータンク2内の温度の高くなった水10を浴槽12へ排水する排水弁、14はロータンク2に水道水を供給するための給水弁、15はロータンク2の上限の水位を検知する上限水位センサー、である。
【0016】
次に動作、作用について説明する。圧縮機3によって圧縮された冷媒は高温高圧の気体となり、凝縮器4に送り込まれる。凝縮器4の凝縮熱でロータンク2内の水10が暖められる。水温センサー11が水10の温度を検知し、水10の温度が所定の温度に達した事を感知すると、制御器(図示せず)よりの信号で排水弁13が開き所定の温度になった水10が浴槽12へ供給される。次に排水により水10の水位が下がり水位センサー11より低くなると、水温センサーが空気に触れ、水温センサー11の温度が下がることで、制御器が排水が終了した事を感知して、排水弁13を閉じ給水弁14を空ける事で水位センサー11より下に位置する凝縮機4が空気に触れることなくロータンク2に温度の低い水の給水が開始される。水10の水位が上昇して上限水位センサー15に達すると制御器が給水弁14を閉じる。尚本発明では、水温センサー11で下限の水位を検知するようにしているが、水温センサー11の代わりに下限の水位を検知する下限水位センサーを設けても良い。このような構成にしたので、従来排水されていたお湯の有効活用が出来る。また水温センサー11で水10の温度を検知することで、浴槽12に入浴に適した温度の湯が貯湯される為、湯温が低いことによる追い炊きが必要がないので更に省エネが図れる。また凝縮機4が空気に触れることが無いため、常に凝縮機4での熱交換を維持出来るので、冷凍サイクルを正常に動作させることができる。
【0017】
【発明の効果】
以上のように、請求項1〜3に記載の冷房装置付きトイレ装置によると、従来排水されていたお湯を省エネ(追い炊きの必要がない)を図りながら、有効活用が出来る冷房装置付きトイレ装置を提供できる。

BACKGROUND OF THE INVENTION
The present invention relates to a toilet apparatus, and more particularly to a toilet apparatus having a cooling function.
[0002]
[Prior art]
As an apparatus for cooling the inside of a toilet room, there is one in which a condenser is disposed in a low tank (see, for example, Patent Document 1).
[0003]
As an apparatus for cooling the inside of a toilet room, there is a toilet apparatus with a cooling apparatus as shown in FIG.
[0004]
In FIG. 2, reference numeral 1 denotes a case, which includes a low tank 2 for storing cleaning water for toilet flushing, a compressor 3, a condenser 4, a decompression means 5, an evaporator 6, and a blower 7 as a cooling device. Built in. The case 1 has an air outlet 8 opened. 9 is a toilet bowl.
[0005]
Next, the operation and action will be described. The refrigerant compressed by the compressor 3 becomes a high-temperature and high-pressure gas and is sent to the condenser 4. In the condenser 4, the refrigerant dissipates heat of condensation in the water filled in the raw tank 2 and condenses into a liquid while maintaining a high pressure. Thereafter, the refrigerant is decompressed by the decompression means 5 and evaporated by the evaporator 6. At this time, wind passes through the evaporator 6 by the blower 7, and the wind blows out from the outlet 8 after being cooled by the heat of vaporization. The evaporated and evaporated refrigerant returns to the compressor 3 and is compressed again, and this is repeated to form a refrigeration cycle. In this way, it is possible to cool air by discharging cold air from the toilet device. Without generating hot air unlike an outdoor unit of a room air conditioner, the generation of cold air and the release of condensed heat are contained in the case of the toilet device, and a compact toilet device with a cooling device can be configured.
[0006]
[Patent Document 1]
JP 2000-96663 A [0007]
[Problems to be solved by the invention]
However, in the conventional toilet device with a cooling device, the heat of condensation generated in the condenser 4 is dissipated to the water in the raw tank 2, so that the temperature of the water in the raw tank 2 rises when the refrigeration cycle is operated for a long time. However, the heat exchange efficiency in the condenser 4 is lowered. Therefore, in order to maintain the heat exchange rate, the water in the raw tank 2 is drained at regular intervals, and new cold water is supplied. Therefore, the heated hot water was wasted. In recent years, effective utilization of resources has been demanded, and effective utilization of drained hot water has been required.
[0008]
This invention solves the said conventional subject, and it aims at providing the toilet apparatus with a cooling device made into the structure which can utilize the hot water drained effectively.
[0009]
[Means for Solving the Problems]
In order to solve the above-described conventional problems, the toilet device with a cooling device of the present invention has a configuration in which water is heated by the heat of the condenser and supplied to the bathtub. As a result, the hot water heated by the condensation heat of the condenser can be effectively used as the hot water in the bathtub without wasting the hot water wastefully, and resource saving and energy saving can be achieved. In addition, the toilet where the toilet device with the air conditioner is installed and the bathroom with the bathtub are all around the water, so they are almost located adjacent to each other (the unit bath is in the same room). The structure that heats the water supplied into the bathtub with heat is considered to be a reasonable combination that is not unreasonable when considering the indoor positional relationship.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 is a configuration in which a compressor, a condenser, an evaporator, a blower, and a cool air generated from the evaporator and the blower are blown into a toilet room, and the condenser is placed in a low tank. The hot water that was previously drained can be used effectively because it is configured to store hot water from the low tank in the bathtub.
[0011]
Since the water temperature sensor is provided in the row tank and the water in the row tank rises to a predetermined temperature and the hot water in the row tank is stored in the bathtub, the invention according to claim 2 is always suitable for bathing. No hot water is required and energy savings can be achieved.
[0012]
Since the invention according to claim 3 has a configuration in which the water temperature sensor is provided at a position higher than the condenser, when the water level falls below the water temperature sensor due to drainage to the bathtub, the water temperature sensor touches the air and the temperature of the water temperature sensor decreases. Thus, since the water supply is configured to start, the water does not run out, the condenser is exposed from the water, heat exchange cannot be performed, and the refrigeration cycle is not maintained.
[0013]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0014]
(Example 1)
FIG. 1 is a schematic diagram of a refrigeration cycle and a method of supplying hot water to a bathtub of a toilet apparatus with a cooling apparatus according to a first embodiment of the present invention. Parts having the same functions as those of the conventional example are given the same reference numerals and description thereof is omitted.
[0015]
In FIG. 1, 10 is water in the low tank, 11 is a water temperature sensor that senses the temperature of the water 10, 12 is a bathtub, 13 is a drain valve that drains the hot water 10 in the low tank 2 to the bathtub 12, and 14. Is a water supply valve for supplying tap water to the low tank 2, and 15 is an upper limit water level sensor for detecting the upper limit water level of the low tank 2.
[0016]
Next, the operation and action will be described. The refrigerant compressed by the compressor 3 becomes a high-temperature and high-pressure gas and is sent to the condenser 4. The water 10 in the raw tank 2 is warmed by the condensation heat of the condenser 4. When the water temperature sensor 11 detects the temperature of the water 10 and senses that the temperature of the water 10 has reached a predetermined temperature, the drain valve 13 is opened by a signal from a controller (not shown) to reach the predetermined temperature. Water 10 is supplied to the bathtub 12. Next, when the water level of the water 10 is lowered by the drainage and becomes lower than the water level sensor 11, the water temperature sensor touches the air and the temperature of the water temperature sensor 11 decreases, so that the controller senses that the drainage is finished, and the drain valve 13 By closing and opening the water supply valve 14, the low temperature water supply to the low tank 2 is started without the condenser 4 positioned below the water level sensor 11 contacting the air. When the water level of the water 10 rises and reaches the upper limit water level sensor 15, the controller closes the water supply valve 14. In the present invention, the lower limit water level is detected by the water temperature sensor 11, but a lower limit water level sensor for detecting the lower limit water level may be provided instead of the water temperature sensor 11. Since it was such a structure, the hot water drained conventionally can be used effectively. Further, by detecting the temperature of the water 10 with the water temperature sensor 11, hot water having a temperature suitable for bathing is stored in the bathtub 12, so that additional cooking due to the low temperature of the hot water is not necessary, thereby further saving energy. In addition, since the condenser 4 does not come into contact with air, heat exchange in the condenser 4 can always be maintained, so that the refrigeration cycle can be operated normally.
[0017]
【The invention's effect】
As described above, according to the toilet device with a cooling device according to any one of claims 1 to 3, the toilet device with a cooling device that can be effectively used while saving energy (no need for additional cooking) for hot water that has been drained conventionally. Can provide.
