Description

本発明は、医療器具の他、電子部品や機械部品などを洗浄する洗浄装置に関するものである。   The present invention relates to a cleaning apparatus for cleaning electronic parts, machine parts and the like in addition to medical instruments.

従来、下記特許文献1に開示されるように、カスト(3)を出入自在に収納するための蓋(2)を有するチャンバー(1)を設け、このチャンバー(1)内に洗浄水を加熱する加熱部(ヒーター5)を設け、前記チャンバー(1)に洗浄水を給水する給水部(シャワーノズル10)とそのチャンバー(1)内の圧力を低下させて前記洗浄水を沸騰させる真空ポンプ(13)とその洗浄水を排水する排水部(排水孔15)とを接続し、前記チャンバー(1)にこのチャンバー(1)とは別の水槽(17)から熱湯を供給する熱湯供給装置を接続した洗浄装置が知られている(請求項4、図面の簡単な説明、第1図)。   Conventionally, as disclosed in Patent Document 1 below, a chamber (1) having a lid (2) for removably storing a cast (3) is provided, and cleaning water is heated in the chamber (1). A heating unit (heater 5) is provided, and a water supply unit (shower nozzle 10) for supplying cleaning water to the chamber (1) and a vacuum pump (13) for boiling the cleaning water by reducing the pressure in the chamber (1). And a drainage part (drainage hole 15) for draining the washing water, and a hot water supply device for supplying hot water from a water tank (17) different from the chamber (1) is connected to the chamber (1). Cleaning devices are known (claim 4, brief description of the drawings, FIG. 1).

より具体的には、洗浄装置は、ヒーター(5)を有するチャンバー(1)と、熱湯ヒーター(24)を有する水槽(17)とを備え、それぞれには水道水が注ぎ込み可能とされている。そして、水槽(17)に注がれた水道水は、熱湯ヒーター(24)により加熱されて、90℃前後の熱湯とされる(公報第2頁右下欄第3−6行)。その後、シャワーバルブ(9)と給湯バルブ(18)とが交互に開かれ、シャワーノズル(10)からの水と水槽(17)からの熱湯とが混合されて、50℃前後の洗浄水がチャンバー(1)内に貯留される(公報第2頁右下欄第11−16行)。その後、チャンバー(1)内を減圧して洗浄水を沸騰させることで被洗浄物の洗浄を図るが、減圧により洗浄水の温度が低下するので、減圧を停止した状態でヒーター(5)を作動させることによる洗浄水の再加熱と、ヒーター(5)を停止した状態で減圧することによる洗浄水の再沸騰とが、数度行われる(公報第3頁左上欄第3行−右上欄第13行)。そして、その間、水槽(17)内には予め熱湯が用意され、次回の洗浄に備えている(公報第3頁右上欄第14−17行)。   More specifically, the cleaning device includes a chamber (1) having a heater (5) and a water tank (17) having a hot water heater (24), and tap water can be poured into each chamber. And the tap water poured into the water tank (17) is heated by a hot water heater (24) to be hot water of about 90 ° C. (publication page 2, lower right column, lines 3-6). Thereafter, the shower valve (9) and the hot water supply valve (18) are alternately opened, and the water from the shower nozzle (10) and the hot water from the water tank (17) are mixed, and washing water at around 50 ° C. is supplied to the chamber. (1) is stored in (Gazette page 2, lower right column, lines 11-16). After that, the chamber (1) is depressurized and the wash water is boiled to clean the object to be cleaned. However, since the temperature of the wash water decreases due to the depressurization, the heater (5) is operated with the depressurization stopped. The cleaning water is reheated by reheating, and the reheating of the cleaning water by reducing the pressure with the heater (5) stopped is performed several times (see page 3, upper left column, line 3-upper right column, number 13). line). In the meantime, hot water is prepared in advance in the water tank (17), and is prepared for the next washing (the third page, the upper right column, lines 14-17).

特開昭60−225565号公報JP 60-225565 A

特許文献1に開示される洗浄装置では、チャンバー(1)内の減圧とヒーター(5)による洗浄水の再加熱とを繰り返す間、水槽(17)において熱湯ヒーター(24)により次回の洗浄用の熱湯が用意される。つまり、ヒーター(5)によりチャンバー(1)内の水を再加熱中も、熱湯ヒーター(24)により水槽(17)内の水が加熱される。従って、チャンバー(1)内のヒーター(5)と、水槽(17)内の熱湯ヒーター(24)とは、同時に作動し得る構成である。   In the cleaning apparatus disclosed in Patent Document 1, while the pressure reduction in the chamber (1) and the reheating of the cleaning water by the heater (5) are repeated, the hot water heater (24) in the water tank (17) is used for the next cleaning. Hot water is prepared. That is, even when the water in the chamber (1) is reheated by the heater (5), the water in the water tank (17) is heated by the hot water heater (24). Therefore, the heater (5) in the chamber (1) and the hot water heater (24) in the water tank (17) can be operated simultaneously.

また、特許文献1に開示される洗浄装置では、シャワーノズル(10)からの水と水槽(17)からの熱湯とを混合して、チャンバー(1)内に50℃前後の洗浄水を貯留するが、水と熱湯とを混ぜるだけで50℃前後の洗浄水を得るため、水槽(17)では必ず所望温度の熱湯を用意する必要がある。従って、チャンバー(1)における洗浄中の時間を利用して、水槽(17)内の水を次回の洗浄に備えて単に加熱するだけでは足りず、必ず所望温度の熱湯を用意する必要がある。そのため、この点からも、チャンバー(1)内のヒーター(5)と、水槽(17)内の熱湯ヒーター(24)とは、同時に作動させる必要がある。   Moreover, in the washing | cleaning apparatus disclosed by patent document 1, the water from a shower nozzle (10) and the hot water from a water tank (17) are mixed, and the washing water at about 50 degreeC is stored in a chamber (1). However, in order to obtain washing water at around 50 ° C. just by mixing water and hot water, it is necessary to prepare hot water at a desired temperature in the water tank (17). Therefore, it is not necessary to simply heat the water in the water tank (17) in preparation for the next cleaning using the time during the cleaning in the chamber (1), and it is necessary to always prepare hot water at a desired temperature. Therefore, also from this point, it is necessary to operate the heater (5) in the chamber (1) and the hot water heater (24) in the water tank (17) at the same time.

チャンバー(1)内のヒーター(5)と、水槽(17)内の熱湯ヒーター(24)とが同時に作動し得る構成の場合、設備(洗浄装置が設置される箇所)の電気容量の範囲内で両ヒーター(5,24)を作動可能に、各ヒーター(5,24)の電気容量を小さく抑えざるを得ない。従って、設備の電気容量に近い比較的大きな電気容量のヒータを、チャンバー(1)内のヒーター(5)として使用できない。このことは、チャンバー(1)内の洗浄水の加熱(特に再加熱)に時間を要し、運転時間を長引かせる原因となる。   In the case where the heater (5) in the chamber (1) and the hot water heater (24) in the water tank (17) can be operated at the same time, within the electric capacity range of the equipment (where the cleaning device is installed) The electric capacity of each heater (5, 24) must be kept small so that both heaters (5, 24) can be operated. Therefore, a heater having a relatively large electric capacity close to the electric capacity of the facility cannot be used as the heater (5) in the chamber (1). This takes time to heat (particularly reheat) the cleaning water in the chamber (1), and causes a prolonged operation time.

また、特許文献1に開示される洗浄装置では、シャワーノズル(10)からの水と水槽(17)からの熱湯とを混合してチャンバー(1)内に温水を貯留するだけであるから、シャワーノズル(10)からの水の温度や給水量、水槽(17)からの熱湯の温度や給水量などにより、チャンバー(1)内に貯留される液温が安定しない。そのため、チャンバー(1)を減圧しても、沸騰が安定せず、洗浄効果も安定しないおそれがある。   Further, in the cleaning device disclosed in Patent Document 1, water from the shower nozzle (10) and hot water from the water tank (17) are mixed and hot water is stored in the chamber (1). The liquid temperature stored in the chamber (1) is not stable due to the temperature and amount of water supplied from the nozzle (10) and the temperature and amount of hot water supplied from the water tank (17). Therefore, even if the pressure in the chamber (1) is reduced, boiling may not be stable and the cleaning effect may not be stable.

本発明が解決しようとする課題は、洗浄槽とは別に予熱タンクを設けると共に洗浄槽のヒータとは別に予熱タンクにもヒータを設けても、設備の電気容量内で効果的に両ヒータを制御して、洗浄槽内の液体の加温時間の短縮と、それによる運転時間の短縮を図ることにある。   The problem to be solved by the present invention is that a preheating tank is provided separately from the cleaning tank and a heater is also provided in the preheating tank separately from the heater of the cleaning tank, and both heaters are effectively controlled within the electrical capacity of the facility. Thus, the heating time of the liquid in the cleaning tank is shortened and the operation time is thereby shortened.

また、洗浄槽における洗浄または濯ぎ中の時間を利用して、予熱タンク内の液体を最終的には必ずしも目標温度にできなくてもそれを目標に加温しておくことで、洗浄槽内へ給水後の加温時間の短縮と、それによる運転時間の短縮を図ることを課題とする。   Also, by using the time during washing or rinsing in the washing tank, even if the liquid in the preheating tank cannot be finally set at the target temperature, it is heated to the target temperature, so that the liquid is put into the washing tank. It aims at shortening of the heating time after water supply, and shortening of the operation time by it.

ところで、電気ヒータに代えて蒸気ヒータや蒸気ジャケットを用いようとする場合、蒸気ヒータなどからの凝縮水は高温となるため、その有効利用が望まれる。そこで、洗浄槽のヒータとして蒸気ヒータなどを用いる場合、その排熱を有効利用して、予熱タンクにおいて洗浄槽内の液体の入れ替え用の液体を加温しておくことを可能とすることを課題とする。   By the way, when it is going to use a steam heater and a steam jacket instead of an electric heater, since the condensed water from a steam heater etc. becomes high temperature, the effective utilization is desired. Then, when using a steam heater etc. as a heater of a washing tank, it is a subject to make it possible to warm up the liquid for exchange of the liquid in a washing tank in a preheating tank effectively using the exhaust heat. And

本発明は、前記課題を解決するためになされたもので、請求項1に記載の発明は、液体が貯留され、その液体に被洗浄物が浸漬される洗浄槽と、この洗浄槽内の液体を加温する洗浄槽加温手段と、前記洗浄槽内の気体を外部へ吸引排出して前記洗浄槽内を減圧する減圧手段と、この減圧手段により減圧された前記洗浄槽内の液相部に外気を導入する液相給気手段と、前記洗浄槽よりも小容量で、前記洗浄槽内へ供給するための液体が貯留される予熱タンクと、この予熱タンク内の液体を加温する予熱タンク加温手段とを備え、前記予熱タンク加温手段は、前記洗浄槽加温手段の停止中に作動するか、前記洗浄槽加温手段の排熱を用いて、前記予熱タンク内の液体を加温し、前記洗浄槽内の液体を設定温度まで加温後、液体を沸騰させるまで前記減圧手段により前記洗浄槽内を減圧した状態で、前記減圧手段の作動を継続させたまま、前記液相給気手段を用いて前記洗浄槽の内外の差圧により前記被洗浄物よりも下方から前記洗浄槽内の液体中に外気を導入して、前記被洗浄物の洗浄または濯ぎを図る動作を実行可能とされ、前記予熱タンク内の液体は、前記設定温度よりも高い温度を目標温度として加温され、前記洗浄槽内の液体を排水後、前記洗浄槽内に、前記予熱タンクからの液体と、前記予熱タンクを介さない液体とを供給した後、前記洗浄槽加温手段により前記洗浄槽内の液体を前記設定温度に調整することを特徴とする洗浄装置である。
請求項1に記載の発明によれば、洗浄槽とは別に予熱タンクを設けると共に洗浄槽加温手段とは別に予熱タンク加温手段を設け、各加温手段が電気ヒータであっても、両電気ヒータが同時に作動することを防止することで、設備の電気容量内で効果的に両タンク内の液体を加温することができる。一方、各加温手段が蒸気ヒータまたは蒸気ジャケットであっても、洗浄槽加温手段の排熱を用いて、予熱タンク内の液体を加温することで、省エネルギーを図ることができる。
また、請求項1に記載の発明によれば、洗浄槽内の液体を沸騰させるまで洗浄槽内を減圧した状態で、被洗浄物よりも下方から洗浄槽内の液体中に外気を導入することで、洗浄槽内の液体を激しく沸騰させることができる。これにより、洗浄槽内の液体を大きく揺動させることができ、被洗浄物の洗浄または濯ぎを効果的に図ることができる。ところで、予熱タンク内の液体は、最終的には必ずしも目標温度にできなくてもそれを目標に加温しておくだけでも足りる。なぜなら、予熱タンク内の液体は、洗浄槽内へ移された後、洗浄槽加温手段により洗浄槽内の液体を設定温度に調整されて用いられるからである。
The present invention has been made to solve the above problems, and the invention according to claim 1 is directed to a cleaning tank in which a liquid is stored and an object to be cleaned is immersed in the liquid, and a liquid in the cleaning tank. Cleaning tank warming means for heating the tank, decompression means for reducing the pressure in the cleaning tank by sucking and discharging the gas in the cleaning tank to the outside, and the liquid phase part in the cleaning tank decompressed by the decompression means A liquid-phase air supply means for introducing outside air, a preheating tank having a smaller capacity than the cleaning tank and storing a liquid to be supplied into the cleaning tank, and a preheating for heating the liquid in the preheating tank A tank warming means, and the preheating tank warming means operates while the washing tank warming means is stopped, or uses the waste heat of the washing tank warming means to drain the liquid in the preheating tank. heating City, after liquid warming to a set temperature in the cleaning tank, prior to boil the liquid While the pressure in the cleaning tank is reduced by the pressure reducing means, the liquid phase air supply means is used to reduce the pressure in the cleaning tank from the lower side by the differential pressure inside and outside the cleaning tank while continuing the operation of the pressure reducing means. It is possible to perform an operation for introducing or cleaning the object to be cleaned by introducing outside air into the liquid in the cleaning tank, and the liquid in the preheating tank has a temperature higher than the set temperature as a target temperature. After being heated and draining the liquid in the cleaning tank, after supplying the liquid from the preheating tank and the liquid not passing through the preheating tank into the cleaning tank, the cleaning tank is heated by the cleaning tank heating means. The cleaning apparatus is characterized in that the liquid in the tank is adjusted to the set temperature .
According to the first aspect of the present invention, a preheating tank is provided separately from the cleaning tank, and a preheating tank heating means is provided separately from the cleaning tank heating means, and each heating means is an electric heater, By preventing the electric heaters from operating simultaneously, the liquid in both tanks can be effectively heated within the electrical capacity of the facility. On the other hand, even if each heating means is a steam heater or a steam jacket, energy can be saved by heating the liquid in the preheating tank using the exhaust heat of the washing tank heating means.
According to the first aspect of the present invention, outside air is introduced into the liquid in the cleaning tank from below the object to be cleaned in a state where the pressure in the cleaning tank is reduced until the liquid in the cleaning tank is boiled. Thus, the liquid in the washing tank can be boiled violently. Thereby, the liquid in the cleaning tank can be greatly swung, and the object to be cleaned can be effectively cleaned or rinsed. By the way, even if the liquid in the preheating tank does not necessarily reach the target temperature in the end, it is sufficient to heat the liquid to the target. This is because the liquid in the preheating tank is used after the liquid in the washing tank is adjusted to the set temperature by the washing tank heating means after being transferred into the washing tank.

請求項2に記載の発明は、液体が貯留され、その液体に被洗浄物が浸漬される洗浄槽と、この洗浄槽内の液体を加温する洗浄槽加温手段と、前記洗浄槽内の気体を外部へ吸引排出して前記洗浄槽内を減圧する減圧手段と、この減圧手段により減圧された前記洗浄槽内の気相部に外気を導入する気相給気手段と、前記洗浄槽よりも小容量で、前記洗浄槽内へ供給するための液体が貯留される予熱タンクと、この予熱タンク内の液体を加温する予熱タンク加温手段とを備え、前記予熱タンク加温手段は、前記洗浄槽加温手段の停止中に作動するか、前記洗浄槽加温手段の排熱を用いて、前記予熱タンク内の液体を加温し、前記洗浄槽内の液体を設定温度まで加温後、前記減圧手段による前記洗浄槽内からの排気を継続して前記洗浄槽内の圧力を低下させる過程で、この減圧による前記洗浄槽内の液体の沸騰中に前記気相給気手段により前記洗浄槽内を液体の沸騰が止むまで瞬時に一時的に復圧することを繰り返す動作により、前記被洗浄物の洗浄または濯ぎを図る動作を実行可能とされ、前記予熱タンク内の液体は、前記設定温度よりも高い温度を目標温度として加温され、前記洗浄槽内の液体を排水後、前記洗浄槽内に、前記予熱タンクからの液体と、前記予熱タンクを介さない液体とを供給した後、前記洗浄槽加温手段により前記洗浄槽内の液体を前記設定温度に調整することを特徴とする洗浄装置である。
請求項2に記載の発明によれば、洗浄槽とは別に予熱タンクを設けると共に洗浄槽加温手段とは別に予熱タンク加温手段を設け、各加温手段が電気ヒータであっても、両電気ヒータが同時に作動することを防止することで、設備の電気容量内で効果的に両タンク内の液体を加温することができる。一方、各加温手段が蒸気ヒータまたは蒸気ジャケットであっても、洗浄槽加温手段の排熱を用いて、予熱タンク内の液体を加温することで、省エネルギーを図ることができる。
また、請求項2に記載の発明によれば、洗浄槽内の液体の沸騰中に、洗浄槽内を瞬時に一時的に復圧することで、液体の沸騰を一気に止めることが繰り返される。従って、洗浄槽内の復圧の度に、それまでの沸騰により液体中に生じていた気泡は、瞬時に凝縮する。この凝縮時の圧力波や圧力差で、液体が攪拌および移送され、被洗浄物の洗浄または濯ぎが図られる。また、被洗浄物がチューブの場合や、被洗浄物が袋穴を有する場合には、沸騰により生じた蒸気をチューブ内や袋穴内に溜め、復圧時にその蒸気溜まりを一気に消して、チューブ内や袋穴内に液体を勢いよく入れることでも、被洗浄物の洗浄または濯ぎが図られる。ところで、予熱タンク内の液体は、最終的には必ずしも目標温度にできなくてもそれを目標に加温しておくだけでも足りる。なぜなら、予熱タンク内の液体は、洗浄槽内へ移された後、洗浄槽加温手段により洗浄槽内の液体を設定温度に調整されて用いられるからである。
The invention according to claim 2 is a cleaning tank in which a liquid is stored and an object to be cleaned is immersed in the liquid, a cleaning tank heating means for heating the liquid in the cleaning tank, A decompression unit that sucks and discharges gas to the outside and depressurizes the inside of the cleaning tank; a gas-phase air supply unit that introduces outside air into the gas-phase part in the cleaning tank decompressed by the decompression unit; and the cleaning tank A preheating tank for storing liquid to be supplied into the cleaning tank and a preheating tank heating means for heating the liquid in the preheating tank, the preheating tank heating means, It operates while the washing tank warming means is stopped or uses the exhaust heat of the washing tank warming means to warm the liquid in the preheating tank and warms the liquid in the washing tank to a set temperature. Thereafter, the pressure in the cleaning tank is reduced by continuing the exhaust from the cleaning tank by the decompression means. In the process of causing the liquid in the cleaning tank to boil due to the reduced pressure, the gas phase air supply means repeatedly repeats instantaneous pressure recovery in the cleaning tank until the liquid stops boiling. An operation for cleaning or rinsing the cleaning object can be performed, and the liquid in the preheating tank is heated with a temperature higher than the set temperature as a target temperature, and the liquid in the cleaning tank is drained, and then the cleaning is performed. After supplying the liquid from the preheating tank and the liquid not passing through the preheating tank into the tank, the liquid in the cleaning tank is adjusted to the set temperature by the cleaning tank heating means. It is a cleaning device.
According to the second aspect of the present invention, the preheating tank is provided separately from the cleaning tank and the preheating tank heating means is provided separately from the cleaning tank heating means, and each heating means is an electric heater. By preventing the electric heaters from operating simultaneously, the liquid in both tanks can be effectively heated within the electrical capacity of the facility. On the other hand, even if each heating means is a steam heater or a steam jacket, energy can be saved by heating the liquid in the preheating tank using the exhaust heat of the washing tank heating means.
According to the second aspect of the present invention, during the boiling of the liquid in the cleaning tank, it is repeated that the boiling of the liquid is stopped at once by instantaneously restoring the pressure in the cleaning tank. Therefore, every time the return pressure in the cleaning tank is restored, the bubbles generated in the liquid by boiling until then are condensed instantly. The liquid is stirred and transferred by the pressure wave and pressure difference during the condensation, and the object to be cleaned is cleaned or rinsed. If the object to be cleaned is a tube, or if the object to be cleaned has a bag hole, the vapor generated by boiling is stored in the tube or the bag hole, and when the pressure is restored, the vapor pool is erased all at once. Also, the object to be cleaned can be cleaned or rinsed by vigorously putting the liquid into the bag hole. By the way, even if the liquid in the preheating tank does not necessarily reach the target temperature in the end, it is sufficient to heat the liquid to the target. This is because the liquid in the preheating tank is used after the liquid in the washing tank is adjusted to the set temperature by the washing tank heating means after being transferred into the washing tank.

請求項3に記載の発明は、前記洗浄槽加温手段と前記予熱タンク加温手段とは、それぞれ電気ヒータから構成され、前記予熱タンクの電気ヒータは、前記洗浄槽の電気ヒータの停止中に作動して、前記洗浄槽内の液体の入れ替え用の液体を加温することを特徴とする請求項1または請求項2に記載の洗浄装置である。 According to a third aspect of the present invention, the cleaning tank warming means and the preheating tank warming means are each configured by an electric heater, and the electric heater of the preheating tank is stopped while the electric heater of the cleaning tank is stopped. operation to a cleaning apparatus according to claim 1 or claim 2, characterized in that for heating the liquid for replacement of the liquid in the cleaning tank.

請求項3に記載の発明によれば、洗浄槽の電気ヒータと予熱タンクの電気ヒータとが同時に作動することを防止することで、設備の電気容量内で効果的に両タンク内の液体を加温することができる。しかも、洗浄槽の電気ヒータが作動していない時間を利用して、後に用いる液体を予熱タンクにて加温しておくことができ、運転時間の短縮を図ることができる。 According to the invention described in claim 3 , by preventing the electric heater of the cleaning tank and the electric heater of the preheating tank from operating simultaneously, the liquid in both tanks can be effectively added within the electric capacity of the equipment. Can be warmed. In addition, the liquid used later can be heated in the preheating tank using the time during which the electric heater of the washing tank is not operated, and the operation time can be shortened.

請求項4に記載の発明は、前記洗浄槽の電気ヒータと前記予熱タンクの電気ヒータとは、双方が並行して作動すると、前記洗浄装置が設置される箇所の設備の使用可能な電気容量を超えるが、片方ずつ作動すると、前記設備の使用可能な電気容量を超えず、前記予熱タンクの電気ヒータのヒータ容量は、前記洗浄槽の電気ヒータのヒータ容量以下であることを特徴とする請求項3に記載の洗浄装置である。 According to a fourth aspect of the present invention, when both the electric heater of the cleaning tank and the electric heater of the preheating tank are operated in parallel, the usable electric capacity of the facility where the cleaning device is installed is set. than, but when activated by one, without exceeding the electrical capacity available of the equipment, the heating capacity of the electric heater preheating tank claims, characterized in that less heating capacity of the electric heater of the washing tub 3. The cleaning apparatus according to 3 .

請求項4に記載の発明によれば、洗浄槽の電気ヒータと予熱タンクの電気ヒータとは、双方が並行して作動すると設備の電気容量を超えるが、片方ずつ作動すると設備の電気容量を超えないので、洗浄槽の電気ヒータの停止中に、予熱タンクの電気ヒータを作動しつつ、予熱タンクの液体を加温しておくことができる。両電気ヒータは、同時に作動することがないため、各電気ヒータの容量を、設備の電気容量に近付けることもできる。 According to the fourth aspect of the invention, the electric heater of the washing tank and the electric heater of the preheating tank exceed the electric capacity of the facility when both operate in parallel, but exceed the electric capacity of the facility when operated one by one. Therefore, the liquid in the preheating tank can be heated while operating the electric heater in the preheating tank while the electric heater in the cleaning tank is stopped. Since both electric heaters do not operate simultaneously, the capacity of each electric heater can be brought close to the electric capacity of the facility.

請求項5に記載の発明は、前記洗浄槽加温手段と前記予熱タンク加温手段とは、それぞれ蒸気ヒータまたは蒸気ジャケットから構成されることを特徴とする請求項1または請求項2に記載の洗浄装置である。 The invention according to claim 5, wherein the cleaning tank heating means and the pre-heating tank heating means, according to claim 1 or claim 2 respectively, characterized in that it is composed of a steam heater or steam jacket It is a cleaning device.

請求項5に記載の発明によれば、各加温手段を蒸気ヒータまたは蒸気ジャケットから構成しても、洗浄槽加温手段の排熱を用いて、予熱タンク内の液体を加温することで、省エネルギーを図ることができる。 According to invention of Claim 5 , even if each heating means is comprised from a steam heater or a steam jacket, the liquid in a preheating tank is heated using the waste heat of a washing tank heating means. , Can save energy.

本発明によれば、洗浄槽とは別に予熱タンクを設けると共に洗浄槽のヒータとは別に予熱タンクにもヒータを設けても、設備の電気容量内で効果的に両ヒータを制御して、洗浄槽内の液体の加温時間の短縮と、それによる運転時間の短縮を図ることができる。   According to the present invention, even if a preheating tank is provided separately from the cleaning tank and a heater is provided in the preheating tank separately from the heater of the cleaning tank, both heaters are effectively controlled within the electrical capacity of the facility, and cleaning is performed. It is possible to shorten the heating time of the liquid in the tank and thereby shorten the operation time.

また、洗浄槽における洗浄または濯ぎ中の時間を利用して、予熱タンク内の液体を最終的には必ずしも目標温度にできなくてもそれを目標に加温しておくだけでも足りる。なぜなら、予熱タンク内の液体は、洗浄槽内へ移された後、洗浄槽加温手段により温度調整されるからである。   Further, it is sufficient to use the time during the washing or rinsing in the washing tank to heat the liquid in the preheating tank to the target temperature even if it cannot be finally set to the target temperature. This is because the temperature of the liquid in the preheating tank is adjusted by the cleaning tank heating means after being transferred into the cleaning tank.

さらに、電気ヒータに代えて蒸気ヒータや蒸気ジャケットを用いようとする場合、洗浄槽加温手段の排熱を用いて、予熱タンク内の液体を加温することで、省エネルギーを図ることができる。   Furthermore, when it is going to use a steam heater or a steam jacket instead of an electric heater, energy can be saved by heating the liquid in a preheating tank using the exhaust heat of a washing tank heating means.

《Preheating tank 4》
The preheating tank 4 is a hollow container having a smaller capacity than the cleaning tank 3. For example, the preheating tank 4 has a half capacity of the cleaning tank 3. In the illustrated example, the preheating tank 4 is formed to open upward, but a lid may be provided as appropriate. However, unlike the washing tank 3, it is not necessary to seal the inside of the preheating tank 4, and it is desirable not to seal it.

《給水手段5》
給水手段5は、洗浄槽3および予熱タンク4へ水を供給する。洗浄槽3および予熱タンク4へ供給する水は、軟水または純水であるのが好ましい。本実施例では、洗浄槽3および予熱タンク4へは、それぞれ、軟水と純水(RO水)の内、所望の水を切り替えて給水可能とされる。
<< Water supply means 5 >>
The water supply means 5 supplies water to the cleaning tank 3 and the preheating tank 4. The water supplied to the washing tank 3 and the preheating tank 4 is preferably soft water or pure water. In the present embodiment, the cleaning tank 3 and the preheating tank 4 can be supplied by switching desired water among soft water and pure water (RO water).

具体的には、図示例の場合、給水手段5は、軟水が通される第一給水路22と、純水が通される第二給水路23とを備える。第一給水路22には第一給水弁24が設けられ、第二給水路23には第二給水弁25が設けられる。第一給水弁24より下流の第一給水路22と、第二給水弁25より下流の第二給水路23とは、共通給水路26として統一され、三方電磁弁27を介して二股に分岐される。この内の一方は、洗浄槽給水路28として洗浄槽3へ導かれ、他方は、予熱タンク給水路29として予熱タンク4へ導かれる。   Specifically, in the illustrated example, the water supply means 5 includes a first water supply path 22 through which soft water passes and a second water supply path 23 through which pure water passes. The first water supply path 22 is provided with a first water supply valve 24, and the second water supply path 23 is provided with a second water supply valve 25. The first water supply path 22 downstream from the first water supply valve 24 and the second water supply path 23 downstream from the second water supply valve 25 are unified as a common water supply path 26 and branched into two branches via a three-way electromagnetic valve 27. The One of them is led to the washing tank 3 as a washing tank water supply path 28, and the other is led to the preheating tank 4 as a preheating tank water supply path 29.

このような構成であるから、第二給水弁25を閉じた状態で第一給水弁24を開くと、洗浄槽3または予熱タンク4へ軟水を供給でき、第一給水弁24を閉じた状態で第二給水弁25を開くと、洗浄槽3または予熱タンク4へ純水を供給できる。また、軟水または純水を洗浄槽3へ供給するか予熱タンク4へ供給するかは、三方電磁弁27により切り替えることができる。   Since it is such a structure, when the 1st water supply valve 24 is opened in the state which closed the 2nd water supply valve 25, soft water can be supplied to the washing tank 3 or the preheating tank 4, and in the state which closed the 1st water supply valve 24 When the second water supply valve 25 is opened, pure water can be supplied to the cleaning tank 3 or the preheating tank 4. Further, whether the soft water or pure water is supplied to the washing tank 3 or the preheating tank 4 can be switched by the three-way solenoid valve 27.

本実施例のように、給水手段5が軟水と純水とを供給できる場合、用途に合わせて水の種類を使い分けることができる。たとえば、洗浄水として軟水を用い、濯ぎ水として純水を用いることができる。但し、第二給水路23および第二給水弁25を省略して、洗浄槽3および予熱タンク4へは軟水のみを供給可能としてもよいし、逆に、第一給水路22および第一給水弁24を省略して、洗浄槽3および予熱タンク4へは純水のみを供給可能としてもよい。   When the water supply means 5 can supply soft water and pure water as in this embodiment, the type of water can be properly used according to the application. For example, soft water can be used as washing water, and pure water can be used as rinsing water. However, the second water supply passage 23 and the second water supply valve 25 may be omitted, and only the soft water may be supplied to the cleaning tank 3 and the preheating tank 4, or conversely, the first water supply passage 22 and the first water supply valve. 24 may be omitted, and only pure water may be supplied to the cleaning tank 3 and the preheating tank 4.

《給液手段6》
給液手段6は、洗浄槽3内へ洗浄剤または濯ぎ剤を供給する。本実施例では、給液手段6は、洗浄槽3内へ洗浄剤を供給する第一給液手段30と、洗浄槽3内へ濯ぎ剤を供給する第二給液手段31とを備える。
<< Liquid supply means 6 >>
The liquid supply means 6 supplies a cleaning agent or a rinsing agent into the cleaning tank 3. In the present embodiment, the liquid supply means 6 includes a first liquid supply means 30 for supplying a cleaning agent into the cleaning tank 3 and a second liquid supply means 31 for supplying a rinsing agent into the cleaning tank 3.

第一給液手段30は、第一タンク32内の洗浄剤を、第一給液路33を介して洗浄槽3内へ供給する。第一給液路33には、第一タンク32の側から順に、第一給液弁34とオリフィス35とが設けられる。洗浄槽3内を減圧した状態で、第一給液弁34を開くことで、洗浄槽3内へ洗浄剤を供給することができる。本実施例では、給水手段5による洗浄水(軟水)に、第一給液手段30による洗浄剤を混入することで、洗浄液とする。   The first liquid supply means 30 supplies the cleaning agent in the first tank 32 into the cleaning tank 3 through the first liquid supply path 33. The first liquid supply path 33 is provided with a first liquid supply valve 34 and an orifice 35 in order from the first tank 32 side. The cleaning agent can be supplied into the cleaning tank 3 by opening the first liquid supply valve 34 in a state where the pressure in the cleaning tank 3 is reduced. In the present embodiment, the cleaning liquid by mixing the cleaning agent by the first liquid supply means 30 into the cleaning water (soft water) by the water supply means 5 is used.

第二給液手段31は、第二タンク36内の濯ぎ剤(たとえば潤滑防錆剤)を、第二給液路37を介して洗浄槽3内へ供給する。第二給液路37には、第二タンク36の側から順に、第二給液弁38とオリフィス39とが設けられる。洗浄槽3内を減圧した状態で、第二給液弁38を開くことで、洗浄槽3内へ濯ぎ剤を供給することができる。本実施例では、給水手段5による濯ぎ水(純水)に、第二給液手段31による濯ぎ剤を混入することで、濯ぎ液とする。   The second liquid supply means 31 supplies a rinsing agent (for example, a lubricating rust preventive agent) in the second tank 36 into the cleaning tank 3 via the second liquid supply path 37. The second liquid supply passage 37 is provided with a second liquid supply valve 38 and an orifice 39 in order from the second tank 36 side. The rinsing agent can be supplied into the cleaning tank 3 by opening the second liquid supply valve 38 in a state where the pressure in the cleaning tank 3 is reduced. In the present embodiment, the rinsing liquid (pure water) by the water supply means 5 is mixed with the rinsing agent by the second liquid supply means 31 to obtain a rinsing liquid.

但し、第一給液手段30と第二給液手段31との内、一方または双方は、所望により省略することができる。たとえば、第二給液手段31を省略して、給水手段5による水だけで濯ぎを行ってもよい。また、第一給液手段30と第二給液手段31とを省略して、給水手段5による水だけで洗浄または濯ぎを行ってもよい。   However, one or both of the first liquid supply means 30 and the second liquid supply means 31 can be omitted as desired. For example, the second liquid supply means 31 may be omitted and rinsing may be performed using only water from the water supply means 5. Alternatively, the first liquid supply means 30 and the second liquid supply means 31 may be omitted, and cleaning or rinsing may be performed using only water from the water supply means 5.

さらに、洗浄剤を含む水を洗浄液とする場合にも、給水手段5による水に予め洗浄剤を混入しておけば、第一給液手段30を省略することができる。つまり、給水手段5は、水を供給する以外に、洗浄剤を含む水、またはその他の洗浄液を、洗浄槽3および予熱タンク4へ供給する手段であってもよい。   Further, when water containing a cleaning agent is used as the cleaning liquid, the first liquid supplying means 30 can be omitted if the cleaning agent is mixed in the water supplied by the water supply means 5 in advance. That is, the water supply means 5 may be means for supplying water containing a cleaning agent or other cleaning liquid to the cleaning tank 3 and the preheating tank 4 in addition to supplying water.

同様に、濯ぎ剤を含む水を濯ぎ液とする場合にも、給水手段5による水に予め濯ぎ剤を注入しておけば、第二給液手段31を省略することができる。つまり、給水手段5は、水を供給する以外に、濯ぎ剤を含む水、またはその他の濯ぎ液を、洗浄槽3および予熱タンク4へ供給する手段であってもよい。   Similarly, when water containing a rinsing agent is used as a rinsing liquid, the second liquid supplying means 31 can be omitted if the rinsing agent is poured into the water supplied by the water supply means 5 in advance. That is, the water supply means 5 may be means for supplying water containing a rinsing agent or other rinsing liquid to the cleaning tank 3 and the preheating tank 4 in addition to supplying water.

《洗浄槽加温手段7》
洗浄槽加温手段7は、洗浄槽3内に貯留された液体を加温する。洗浄槽3内の貯留液を加温する方法は特に問わないが、図示例の洗浄槽加温手段7は、洗浄槽3内の底部に配置された電気ヒータ(以下、洗浄槽電気ヒータという)40である。この場合、洗浄槽3内に液体(洗浄液または濯ぎ液)を貯留した状態で、洗浄槽電気ヒータ40に通電することで、洗浄槽3内の液体を加温することができる。本実施例では、洗浄槽電気ヒータ40は、オンオフ制御される。
<< Washing tank heating means 7 >>
The cleaning tank warming means 7 warms the liquid stored in the cleaning tank 3. Although the method for heating the stored liquid in the cleaning tank 3 is not particularly limited, the cleaning tank heating means 7 in the illustrated example is an electric heater (hereinafter referred to as a cleaning tank electric heater) disposed at the bottom of the cleaning tank 3. 40. In this case, the liquid in the cleaning tank 3 can be heated by energizing the cleaning tank electric heater 40 with the liquid (cleaning liquid or rinsing liquid) stored in the cleaning tank 3. In this embodiment, the washing tank electric heater 40 is controlled to be turned on / off.

《減圧手段8》
減圧手段8は、洗浄槽3内の気体を、排気路41を介して外部へ吸引排出して、洗浄槽3内を減圧する。図示例の場合、排気路41には、洗浄槽3の側から順に、気水分離器42、熱交換器43、逆止弁44、および水封式の真空ポンプ45が設けられる。
<< Pressure reducing means 8 >>
The decompression means 8 sucks and discharges the gas in the cleaning tank 3 to the outside through the exhaust path 41 to decompress the inside of the cleaning tank 3. In the case of the illustrated example, the exhaust passage 41 is provided with a steam / water separator 42, a heat exchanger 43, a check valve 44, and a water ring vacuum pump 45 in order from the cleaning tank 3 side.

気水分離器42は、洗浄槽3内からの気体中に含まれる液滴や固形物を除去する。言い換えれば、気水分離器42は、洗浄槽3内からの蒸気中に含まれる液滴を捕捉して、蒸気の乾き度を向上すると共に、蒸気中に含まれる固形物を捕捉して、下流の熱交換器43における詰まりを防止する。   The steam separator 42 removes liquid droplets and solids contained in the gas from the cleaning tank 3. In other words, the steam separator 42 captures the droplets contained in the steam from the cleaning tank 3 to improve the dryness of the steam, and captures the solid matter contained in the steam, thereby downstream. The clogging in the heat exchanger 43 is prevented.

気水分離器42は、その構成を特に問わないが、たとえばデミスター46が用いられる。具体的には、図示例の気水分離器42は、中空容器47と、この容器47内を上部空間と下部空間とに仕切るよう設けられるデミスター46とを備える。気水分離器42の容器47は、デミスター46より下部空間の側壁に、洗浄槽3の気相部からの配管が接続され、デミスター46より上部空間の側壁または上壁に、熱交換器43への配管が接続される。さらに、気水分離器42の容器47は、デミスター46より下部空間の底壁に、洗浄槽3の液相部への配管48が接続される。   The configuration of the steam separator 42 is not particularly limited, but for example, a demister 46 is used. Specifically, the air / water separator 42 in the illustrated example includes a hollow container 47 and a demister 46 provided to partition the inside of the container 47 into an upper space and a lower space. The vessel 47 of the steam separator 42 is connected to the side wall of the lower space from the demister 46 and a pipe from the gas phase part of the cleaning tank 3 to the heat exchanger 43 to the side wall or upper wall of the upper space from the demister 46. Are connected. Further, the pipe 47 to the liquid phase part of the cleaning tank 3 is connected to the bottom wall of the lower space of the container 47 of the steam separator 42 from the demister 46.

熱交換器43は、排気路41内の蒸気を冷却し凝縮させる。熱交換器43は、その種類を特に問わないが、たとえばプレート式熱交換器である。熱交換器43には、熱交給水弁49を介して水が供給され排出される。従って、洗浄槽3内からの蒸気は、熱交換器43において、熱交給水弁49からの水と間接熱交換して、凝縮を図られる。   The heat exchanger 43 cools and condenses the steam in the exhaust passage 41. Although the kind in particular is not ask | required for the heat exchanger 43, it is a plate-type heat exchanger, for example. Water is supplied to the heat exchanger 43 through a heat exchange water supply valve 49 and discharged. Therefore, the steam from the cleaning tank 3 is subjected to indirect heat exchange with the water from the heat exchange water supply valve 49 in the heat exchanger 43 to be condensed.

水封式の真空ポンプ45は、周知のとおり、封水と呼ばれる水が供給されて作動される。そのために、真空ポンプ45には、封水給水弁50を介して水が供給され排出される。封水給水弁50は、真空ポンプ45の作動の有無と連動して、開閉される。   As is well known, the water-sealed vacuum pump 45 is operated by supplying water called sealed water. Therefore, water is supplied to the vacuum pump 45 through the sealed water supply valve 50 and discharged. The sealed water supply valve 50 is opened and closed in conjunction with the presence or absence of the operation of the vacuum pump 45.

ところで、熱交給水弁49は、減圧手段8を作動させる際には常に開くようにしてもよいが、次のように開閉制御されてもよい。すなわち、減圧開始当初は洗浄槽3内から主として空気を抜くことになるので、熱交換器43において蒸気を凝縮させる必要性に乏しいことを考慮し、熱交給水弁49を閉じた状態で真空ポンプ45を作動させて洗浄槽3内の減圧を開始後、それに遅れる設定タイミングで熱交給水弁49を開いてもよい。また、その後、洗浄槽3内の減圧に伴って貯留液が真空冷却されるので、洗浄槽3内の液体の温度変化に伴い熱交換器43への給水量を調整してもよい。この場合、熱交給水弁49は、開度調整可能な弁から構成される。   Incidentally, the heat exchange water supply valve 49 may be always opened when the decompression means 8 is operated, but may be controlled to open and close as follows. In other words, since the air is mainly extracted from the cleaning tank 3 at the beginning of the pressure reduction, the vacuum pump with the heat exchange water valve 49 closed in consideration of the lack of necessity of condensing steam in the heat exchanger 43. After starting the pressure reduction in the washing tank 3 by operating 45, the heat exchange water supply valve 49 may be opened at a set timing delayed. Moreover, since the stored liquid is vacuum-cooled as the pressure in the cleaning tank 3 is reduced, the amount of water supplied to the heat exchanger 43 may be adjusted in accordance with the temperature change of the liquid in the cleaning tank 3. In this case, the heat exchange water supply valve 49 is composed of a valve whose opening degree can be adjusted.

《気相給気手段9》
気相給気手段9は、減圧された洗浄槽3内の気相部へ、気相給気路51を介して外気を導入する。気相給気路51には、洗浄槽3へ向かって順に、フィルター52および気相給気弁53が設けられる。従って、洗浄槽3内が減圧された状態で気相給気弁53を開くと、洗浄槽3の内外の差圧により、フィルター52を介した空気を洗浄槽3内へ導入して、洗浄槽3内を復圧することができる。気相給気弁53を電磁弁から構成することで、気相給気弁53を素早く開放して、洗浄槽3内を瞬時に復圧することができる。
<< Gas phase air supply means 9 >>
The gas-phase air supply means 9 introduces outside air to the gas phase portion in the depressurized cleaning tank 3 through the gas-phase air supply path 51. The gas phase air supply path 51 is provided with a filter 52 and a gas phase air supply valve 53 in order toward the cleaning tank 3. Therefore, when the gas-phase gas supply valve 53 is opened in a state where the pressure in the cleaning tank 3 is reduced, air through the filter 52 is introduced into the cleaning tank 3 due to a differential pressure inside and outside the cleaning tank 3, and the cleaning tank 3 The pressure inside 3 can be restored. By configuring the gas-phase supply valve 53 from an electromagnetic valve, the gas-phase supply valve 53 can be quickly opened and the pressure in the cleaning tank 3 can be instantaneously restored.

《液相給気手段10》
液相給気手段10は、減圧された洗浄槽3内の液相部へ、液相給気路54を介して外気を導入する。液相給気路54には、洗浄槽3へ向かって順に、フィルター55および液相給気弁56が設けられる。従って、洗浄槽3内が減圧された状態で液相給気弁56を開くと、洗浄槽3の内外の差圧により、フィルター55を介した空気を、洗浄槽3内の貯留液中に導入することができる。但し、液相給気手段10は、差圧により外気を自然に導入する以外に、圧縮機やポンプから強制的に空気を送り込んでもよい。また、所望により、空気以外の気体を送り込んでもよい。
<< Liquid phase air supply means 10 >>
The liquid phase air supply means 10 introduces outside air into the liquid phase portion in the cleaning tank 3 whose pressure has been reduced through the liquid phase air supply path 54. A filter 55 and a liquid phase air supply valve 56 are provided in the liquid phase air supply path 54 in order toward the cleaning tank 3. Accordingly, when the liquid-phase air supply valve 56 is opened in a state where the pressure in the cleaning tank 3 is reduced, air through the filter 55 is introduced into the stored liquid in the cleaning tank 3 due to the differential pressure inside and outside the cleaning tank 3. can do. However, the liquid phase air supply means 10 may forcibly send air from a compressor or a pump in addition to naturally introducing outside air by a differential pressure. Further, if desired, a gas other than air may be fed.

ところで、液相給気路54からの空気は、洗浄槽3内の底部に設けた液相給気ノズル57を介して、洗浄槽3内の貯留液中に導入される。液相給気ノズル57は、洗浄槽3内の底部に、横向きに配置されたパイプである。液相給気ノズル57は、洗浄槽3内の底部ではあるが底面から離隔して、水平に保持されている。そして、液相給気ノズル57には、パイプの延出方向へ沿って設定間隔で、パイプの周側壁にノズル孔(図示省略)が下方へ開口して形成されている。これにより、洗浄槽3内が減圧された状態で液相給気弁56を開くと、洗浄槽3内の貯留液中に均質に空気を導入することができる。   By the way, the air from the liquid phase supply path 54 is introduced into the stored liquid in the cleaning tank 3 through the liquid phase supply nozzle 57 provided at the bottom of the cleaning tank 3. The liquid-phase air supply nozzle 57 is a pipe disposed laterally at the bottom of the cleaning tank 3. The liquid phase air supply nozzle 57 is a bottom portion in the cleaning tank 3 but is separated from the bottom surface and is held horizontally. The liquid-phase air supply nozzle 57 is formed with nozzle holes (not shown) that open downward on the peripheral side wall of the pipe at set intervals along the pipe extending direction. Thereby, if the liquid phase air supply valve 56 is opened in a state where the inside of the cleaning tank 3 is depressurized, air can be introduced uniformly into the stored liquid in the cleaning tank 3.

《洗浄槽排水手段11》
洗浄槽排水手段11は、洗浄槽3内の液体を、洗浄槽3の底部から洗浄槽排水路58を介して排出する。洗浄槽排水路58には、洗浄槽排水弁59が設けられる。洗浄槽3内に液体が貯留された状態で洗浄槽排水弁59を開くと、その液体を洗浄槽3外へ自然に排出することができる。なお、図示例では、前述した気水分離器42から洗浄槽3の液相部への配管48は、洗浄槽排水路58の内、洗浄槽3から洗浄槽排水弁59への中途に、接続されている。
<< Draining means 11 for washing tank >>

予熱タンク加温手段14は、予熱タンク4内に貯留された液体を加温する。予熱タンク4内の貯留液を加温する方法は特に問わないが、図示例の予熱タンク加温手段14は、予熱タンク4内の底部に配置された電気ヒータ(以下、予熱タンク電気ヒータという)62である。この場合、予熱タンク4内に液体(洗浄水または濯ぎ水)を貯留した状態で、予熱タンク電気ヒータ62に通電することで、予熱タンク4内の液体を加温することができる。本実施例では、予熱タンク電気ヒータ62は、オンオフ制御される。
<< Preheating tank heating means 14 >>
The preheating tank warming means 14 warms the liquid stored in the preheating tank 4. Although the method for heating the stored liquid in the preheating tank 4 is not particularly limited, the preheating tank heating means 14 in the illustrated example is an electric heater disposed at the bottom of the preheating tank 4 (hereinafter referred to as a preheating tank electric heater). 62. In this case, the liquid in the preheating tank 4 can be heated by energizing the preheating tank electric heater 62 with the liquid (washing water or rinsing water) stored in the preheating tank 4. In this embodiment, the preheating tank electric heater 62 is on / off controlled.

予熱タンク電気ヒータ62は、洗浄槽電気ヒータ40と同じヒータ容量とするのが好ましい。本実施例では、洗浄槽電気ヒータ40と予熱タンク電気ヒータ62とは、同一の電気ヒータが用いられる。   The preheating tank electric heater 62 preferably has the same heater capacity as the washing tank electric heater 40. In the present embodiment, the cleaning tank electric heater 40 and the preheating tank electric heater 62 are the same electric heater.

It is preferable to use a heater with a capacity that can be utilized in the future. Therefore, the heater capacity of each electric heater 40, 62 is changed according to the location where the cleaning apparatus 1 is installed. The washing tank electric heater 40 and the preheating tank electric heater 62 are supplied with power through a common breaker (not shown). Even in such a configuration, as will be described later, the preheating tank electric heater 62 operates only while the washing tank electric heater 40 is stopped.

The heater capacity of the cleaning tank electric heater 40 is limited to equipment other than the electric heaters 40 and 62 (of course, equipment supplied from the same breaker). ) Is set to a value less than the value obtained by subtracting the electrical capacity of the facility. Further, the heater capacity of the preheating tank electric heater 62 is set to be equal to or less than the heater capacity of the cleaning tank electric heater 40 and is typically set to be the same as the heater capacity of the cleaning tank electric heater 40 as described above. And the value which added the heater capacity | capacitance of both the electric heaters 40 and 62 exceeds the value which pulled the electric capacity used with apparatuses other than both the electric heaters 40 and 62 from the electric capacity of the installation. In consideration of such requirements, the heater capacity of each of the electric heaters 40 and 62 is determined.

A water supply pump 64 and a hot water supply valve 65 are provided in the water supply path 63 in order from the preheating tank 4 side. Therefore, when the hot water supply valve 65 is opened with the water pump 64 operated, the liquid in the preheating tank 4 can be fed into the cleaning tank 3. However, when the preheating tank 4 is arranged above the washing tank 3, the water supply pump 64 may be omitted.

On the other hand, the preheating tank 4 is provided with a preheating tank liquid temperature sensor 17 for detecting the temperature of the liquid phase portion in the preheating tank 4.

また、洗浄槽3には、洗浄槽液位検出器(図示省略)が設けられる。この液位検出器は、洗浄槽3内に設定液位まで液体が貯留されたか否か、洗浄槽3内の貯留液が排水されたか否か、洗浄槽3内に上限液位以上の液体が貯留されていないか否かを検出する。   The cleaning tank 3 is provided with a cleaning tank liquid level detector (not shown). This liquid level detector detects whether or not the liquid has been stored in the cleaning tank 3 up to the set liquid level, whether or not the stored liquid in the cleaning tank 3 has been drained, and whether or not the liquid above the upper limit liquid level has been stored in the cleaning tank 3. It is detected whether it is not stored.

The controller 70 then cleans or rinses the article 2 to be cleaned in the cleaning tank 3 according to a predetermined procedure (program) as described below.

次に、本実施例の洗浄装置1の運転方法の一例について説明する。
本実施例の洗浄装置1は、前述したとおり、洗浄槽3の他、予熱タンク4を備える。洗浄槽3では、被洗浄物2の洗浄や濯ぎが行われるが、その間、予熱タンク4では、洗浄槽3内の液体の次回の入れ替え用の液体の加温が行われる。そこで、まず、洗浄槽3における被洗浄物2の洗浄や濯ぎについて説明し、その後、その間に行われる予熱タンク4における液体の加温について説明する。
Next, an example of the operation method of the cleaning apparatus 1 of the present embodiment will be described.
The washing | cleaning apparatus 1 of a present Example is provided with the preheating tank 4 other than the washing tank 3 as mentioned above. In the cleaning tank 3, the object to be cleaned 2 is cleaned and rinsed, and in the meantime, in the preheating tank 4, the liquid for the next replacement of the liquid in the cleaning tank 3 is heated. Therefore, first, cleaning and rinsing of the object to be cleaned 2 in the cleaning tank 3 will be described, and thereafter, heating of the liquid in the preheating tank 4 performed during that time will be described.

図2は、本実施例の洗浄装置1の運転方法の一例を示すフローチャートであり、洗浄槽3における運転内容を示している。   FIG. 2 is a flowchart showing an example of the operation method of the cleaning apparatus 1 of the present embodiment, and shows the operation content in the cleaning tank 3.

洗浄槽3では、予洗工程S1、一以上の洗浄工程S2〜S3、一以上の濯ぎ工程S4〜S6、および液切り工程S7の内から選択された工程を順次に実行する。より具体的には、図示例の場合、予洗工程S1、第一洗浄工程S2、第二洗浄工程S3、第一濯ぎ工程S4、第二濯ぎ工程S5、第三濯ぎ工程S6、および液切り工程S7の内、選択された工程を順次に実行する。   In the cleaning tank 3, a process selected from the pre-cleaning process S1, one or more cleaning processes S2 to S3, one or more rinsing processes S4 to S6, and a liquid draining process S7 is sequentially executed. More specifically, in the illustrated example, the pre-washing step S1, the first washing step S2, the second washing step S3, the first rinsing step S4, the second rinsing step S5, the third rinsing step S6, and the liquid draining step S7. Of these, the selected processes are executed sequentially.

これら工程の開始前に、洗浄槽3内には被洗浄物2が収容され、洗浄槽3の蓋20は気密に閉じられる。この際、被洗浄物2は、液相給気ノズル57より上方に配置され、所望により、網状のバスケットなどに入れられて洗浄槽3内に収容される。   Before the start of these steps, the object to be cleaned 2 is accommodated in the cleaning tank 3, and the lid 20 of the cleaning tank 3 is closed in an airtight manner. At this time, the object to be cleaned 2 is disposed above the liquid-phase air supply nozzle 57 and, if desired, is placed in a net-like basket or the like and accommodated in the cleaning tank 3.

予洗工程S1と洗浄工程S2〜S3とは実施可能な動作が共通しているので、予洗工程S1を洗浄工程S2〜S3の一種と捉えることもできる。また、洗浄工程S2〜S3と濯ぎ工程S4〜S6とは、洗浄槽3内に貯留される液体が洗浄液か濯ぎ液かの差にあるので、濯ぎ工程S4〜S6を洗浄工程S2〜S3の一種と捉えることもできる。さらに、洗浄工程S2〜S3や濯ぎ工程S4〜S6において、洗浄槽3内の液体の温度を高温にすることで、被洗浄物2の消毒を図ることもできるので、洗浄工程S2〜S3や濯ぎ工程S4〜S6には消毒工程を含むと捉えることもできる。   Since the prewashing step S1 and the washing steps S2 to S3 have common operations, the prewashing step S1 can be regarded as a kind of the washing steps S2 to S3. Further, since the cleaning steps S2 to S3 and the rinsing steps S4 to S6 are different in whether the liquid stored in the cleaning tank 3 is a cleaning solution or a rinsing solution, the rinsing steps S4 to S6 are a kind of the cleaning steps S2 to S3. It can also be taken as. Further, in the cleaning steps S2 to S3 and the rinsing steps S4 to S6, the temperature of the liquid in the cleaning tank 3 can be increased to disinfect the object 2 to be cleaned. It can also be understood that the steps S4 to S6 include a disinfection step.

《予洗工程S1および各洗浄工程S2,S3》
予洗工程S1および各洗浄工程S2,S3では、液切り動作、給水動作、洗浄剤投入動作、加温動作、保温動作、冷却動作、復圧動作、および排水動作の内、選択された動作を順次に実行する。
<< Prewashing step S1 and each washing step S2, S3 >>
In the pre-washing step S1 and each of the washing steps S2 and S3, the selected operation among the liquid draining operation, the water supply operation, the cleaning agent charging operation, the warming operation, the heat retaining operation, the cooling operation, the recuperation operation, and the draining operation is sequentially performed. To run.

〈液切り動作〉
液切り動作は、減圧手段8により洗浄槽3内を減圧する。具体的には、第一給水弁24、第二給水弁25、第一給液弁34、第二給液弁38、気相給気弁53、液相給気弁56、洗浄槽排水弁59を閉じると共に、洗浄槽電気ヒータ40を停止した状態で、減圧手段8を作動させればよい。これにより、洗浄槽3内の気体を外部へ吸引排出して、洗浄槽3内を減圧することができる。
<Liquid draining operation>
In the liquid draining operation, the pressure in the cleaning tank 3 is reduced by the pressure reducing means 8. Specifically, the first water supply valve 24, the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, the gas phase air supply valve 53, the liquid phase air supply valve 56, and the washing tank drain valve 59. And the pressure reducing means 8 may be operated with the washing tank electric heater 40 stopped. Thereby, the gas in the washing tank 3 can be sucked and discharged to the outside, and the inside of the washing tank 3 can be decompressed.

被洗浄物2が濡れている状況で、液切り動作として、被洗浄物2に付着の液体の飽和蒸気圧以下まで洗浄槽3内を減圧することで、液体を沸騰させて蒸発させ、被洗浄物2からの液切りを図ることができる。その後、減圧手段8を停止した状態で、気相給気弁53を開けることで、洗浄槽3内は復圧される。   While the object to be cleaned 2 is wet, as a liquid draining operation, the liquid is boiled and evaporated by reducing the pressure in the cleaning tank 3 to the saturated vapor pressure or less of the liquid adhering to the object 2 to be cleaned. Liquid drainage from the object 2 can be achieved. Thereafter, the pressure inside the cleaning tank 3 is restored by opening the gas supply valve 53 with the decompression means 8 stopped.

このような減圧と復圧とは、一回に限らず複数回行ってもよい。たとえば、被洗浄物2がチューブの場合、洗浄槽3内を減圧後に復圧することで、復圧時にチューブ内へ空気を導入することができる。そして、その復圧後、洗浄槽3内を再び減圧すれば、導入した空気を膨張させたり、残液を蒸発させたりして、被洗浄物2からの液切りを一層確実に図ることができる。   Such decompression and return pressure are not limited to one time and may be performed a plurality of times. For example, when the object to be cleaned 2 is a tube, air can be introduced into the tube at the time of decompression by restoring the pressure inside the cleaning tank 3 after decompressing. If the pressure in the cleaning tank 3 is reduced again after the pressure is restored, the introduced air is expanded or the remaining liquid is evaporated, so that the liquid can be drained from the object to be cleaned 2 more reliably. .

以上から分かるように、液切り動作は、洗浄槽3内の液体を入れ替える際や、洗浄または濯ぎ後に被洗浄物2を乾燥させる際に行うのが好ましい。前者の場合、入れ替える前後の液体が混ざるのを防止できる。また、後者の場合、後述する液切り工程における液切り動作となる。   As can be seen from the above, the liquid draining operation is preferably performed when the liquid in the cleaning tank 3 is replaced, or when the object to be cleaned 2 is dried after cleaning or rinsing. In the former case, it is possible to prevent the liquid before and after replacement from being mixed. In the latter case, a liquid draining operation is performed in a liquid draining process described later.

設定圧力まで洗浄槽3内を減圧するか、設定時間だけ洗浄槽3内を減圧するか、設定圧力まで洗浄槽3内を減圧して設定時間だけ保持するか、洗浄槽3内の減圧と復圧とを所望に繰り返すかした後、液切り動作を終了する。つまり、減圧手段8の作動を停止した状態で、気相給気弁53を開けて洗浄槽3内を大気圧まで復圧して、液切り動作を終了する。   The inside of the cleaning tank 3 is depressurized to the set pressure, the inside of the cleaning tank 3 is depressurized for a set time, the inside of the wash tank 3 is depressurized to the set pressure and held for the set time, or the pressure in the wash tank 3 is reduced and restored. After repeating the pressure as desired, the draining operation is terminated. That is, with the operation of the decompression means 8 stopped, the vapor supply valve 53 is opened to restore the pressure in the cleaning tank 3 to atmospheric pressure, and the liquid draining operation is completed.

〈給水動作〉
給水動作は、給水手段5を用いて、また場合により送水手段15も用いて、洗浄槽3内へ水を供給する。給水手段5による洗浄槽3内への給水は、第二給水弁25、第一給液弁34、第二給液弁38、液相給気弁56、洗浄槽排水弁59を閉じる一方、気相給気弁53を開くと共に、洗浄槽電気ヒータ40および減圧手段8を停止した状態で、第一給水弁24を開けばよい。この際、三方電磁弁27は、共通給水路26と洗浄槽給水路28とを連通させる。これにより、洗浄水が、洗浄槽3内へ供給される。この給水時、洗浄槽3内の空気は、気相給気路51を逆流して、洗浄槽3外へ排出される。但し、給水動作では、気相給気弁53を閉じる代わりに、減圧手段8を作動させてもよい。洗浄槽3内を減圧しつつ給水することで、被洗浄物2がたとえばチューブの場合、チューブ内から空気を追い出すことができる。
<Water supply operation>
In the water supply operation, water is supplied into the cleaning tank 3 using the water supply means 5 and, optionally, the water supply means 15. Water supply to the cleaning tank 3 by the water supply means 5 is performed while the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, the liquid phase air supply valve 56, and the cleaning tank drain valve 59 are closed. The first water supply valve 24 may be opened while the phase air supply valve 53 is opened and the washing tank electric heater 40 and the pressure reducing means 8 are stopped. At this time, the three-way solenoid valve 27 causes the common water supply path 26 and the cleaning tank water supply path 28 to communicate with each other. As a result, the cleaning water is supplied into the cleaning tank 3. During this water supply, the air in the cleaning tank 3 flows back through the gas-phase air supply path 51 and is discharged out of the cleaning tank 3. However, in the water supply operation, the pressure reducing means 8 may be operated instead of closing the gas phase air supply valve 53. By supplying water while depressurizing the inside of the cleaning tank 3, when the object to be cleaned 2 is a tube, for example, air can be expelled from the tube.

また、後述するように、予熱タンク4において既に熱水(温水を含む)が用意されている場合には、送水手段15による予熱タンク4からの熱水に、給水手段5による水を混ぜて用いることもできる。予熱タンク4から洗浄槽3内への送水は、送水ポンプ64を作動させた状態で給湯弁65を開ければよい。予熱タンク4からの熱水と、給水手段5からの水とを混ぜて用いる場合、熱水と水とを交互に給水してもよいし、熱水と水とを同時に並行して給水してもよい。   As will be described later, when hot water (including hot water) is already prepared in the preheating tank 4, the hot water from the preheating tank 4 by the water supply means 15 is mixed with the water from the water supply means 5. You can also. Water supply from the preheating tank 4 into the cleaning tank 3 may be performed by opening the hot water supply valve 65 in a state where the water supply pump 64 is operated. When the hot water from the preheating tank 4 and the water from the water supply means 5 are mixed and used, hot water and water may be supplied alternately, or hot water and water are supplied simultaneously in parallel. Also good.

いずれにしても、次に予熱タンク4内に貯留して加温しようとする水の種類(軟水または純水)が変わる場合があることを考慮して、予熱タンク4内の熱水を使い切りつつ、足りない分を給水手段5から給水するのがよい。また、予熱タンク4内の熱水を全て洗浄槽3内へ送っても、給水手段5による水が混ぜられることで、洗浄槽3内の水は後述する加温目標温度よりも低い温度となるように、予熱タンク4の容量などが決められる。   In any case, the hot water in the preheating tank 4 is used up in consideration of the fact that the type of water (soft water or pure water) to be stored and heated in the preheating tank 4 may change. It is better to supply the missing amount from the water supply means 5. Moreover, even if all the hot water in the preheating tank 4 is sent into the cleaning tank 3, the water in the water supply means 5 is mixed so that the water in the cleaning tank 3 has a temperature lower than the heating target temperature described later. In this way, the capacity of the preheating tank 4 is determined.

このようにして、洗浄槽3内の設定水位まで洗浄水が供給されると、洗浄槽液位検出器がそれを検知して、第一給水弁24を閉じたり、給湯弁65を閉じると共に送水ポンプ64を停止したりして、給水動作を終了する。なお、減圧手段8を作動させていた場合、減圧手段8の作動を停止すると共に気相給気弁53を一気に開けることで、被洗浄物2がたとえばチューブの場合、チューブ内へ洗浄水を一気に流入させて、洗浄効果を高めることができる。但し、引き続いて洗浄剤投入動作を実施する場合には、減圧手段8の作動を継続すると共に、気相給気弁53を閉じたままで、洗浄剤投入動作へ移行してもよい。   In this way, when the cleaning water is supplied up to the set water level in the cleaning tank 3, the cleaning tank liquid level detector detects it and closes the first water supply valve 24 or the hot water supply valve 65 and supplies water. The pump 64 is stopped or the water supply operation is terminated. In addition, when the decompression means 8 is operated, the operation of the decompression means 8 is stopped and the vapor supply valve 53 is opened at a stroke, so that when the object to be cleaned 2 is a tube, for example, the cleaning water is poured into the tube all at once. The cleaning effect can be enhanced by flowing in. However, when the cleaning agent charging operation is subsequently performed, the operation of the decompression unit 8 may be continued, and the transition to the cleaning agent charging operation may be performed while the gas-phase supply valve 53 is closed.

〈洗浄剤投入動作〉
洗浄剤投入動作は、給液手段6により洗浄槽3内へ洗浄剤を供給する。本実施例では、減圧手段8により洗浄槽3内を減圧後、第一給液手段30により洗浄槽3内へ洗浄剤を引き込むことで、洗浄槽3内の洗浄水に洗浄剤を混入して洗浄液とする。具体的には、第一給水弁24、第二給水弁25、第一給液弁34、第二給液弁38、気相給気弁53、液相給気弁56、洗浄槽排水弁59を閉じると共に、洗浄槽電気ヒータ40を停止した状態で、減圧手段8を作動させて、洗浄槽3内を所望まで減圧した後、減圧手段8を停止させた状態で、第一給液弁34を開けばよい。
<Cleaning agent operation>
In the cleaning agent charging operation, the cleaning agent is supplied into the cleaning tank 3 by the liquid supply means 6. In this embodiment, after the pressure in the cleaning tank 3 is reduced by the pressure reducing means 8, the cleaning agent is mixed into the cleaning water in the cleaning tank 3 by drawing the cleaning agent into the cleaning tank 3 by the first liquid supply means 30. Use cleaning solution. Specifically, the first water supply valve 24, the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, the gas phase air supply valve 53, the liquid phase air supply valve 56, and the washing tank drain valve 59. In the state where the cleaning tank electric heater 40 is stopped and the pressure reducing means 8 is operated to reduce the pressure in the cleaning tank 3 to a desired level, the pressure reducing means 8 is stopped and the first liquid supply valve 34 is stopped. Just open it.

設定時間だけ第一給液弁34を開くなどして、所望量の洗浄剤を洗浄槽3内へ供給した後、第一給液弁34を閉じる一方、気相給気弁53または液相給気弁56を開けて、洗浄剤投入動作を終了する。被洗浄物2がチューブである場合や、被洗浄物2が袋穴を有している場合、気相給気弁53を開いて洗浄槽3内を復圧することで、チューブ内や袋穴内に液体を入れることができる。一方、液相給気弁56を開いて液相部に空気を入れる場合、洗浄槽3内の液体を揺らすことができ、これにより洗浄剤と洗浄水との混合を図り、短時間で洗浄剤を洗浄水中に均一に拡散させることができる。また、液相部へ供給された空気は、洗浄槽3内の液体中を上昇し、やがて気相部へ到達する。気相部の圧力が上昇することで、気相給気弁53を開いた場合と同様の作用効果を得ることができる。具体的には、被洗浄物2がたとえばチューブの場合、チューブ内に液体を入れることができる。   After supplying a desired amount of cleaning agent into the cleaning tank 3 by opening the first liquid supply valve 34 for a set time or the like, the first liquid supply valve 34 is closed while the gas phase air supply valve 53 or the liquid phase supply is closed. The air valve 56 is opened to finish the cleaning agent charging operation. When the object to be cleaned 2 is a tube, or when the object to be cleaned 2 has a bag hole, the gas-phase air supply valve 53 is opened and the pressure in the cleaning tank 3 is restored, so that the inside of the tube or the bag hole is obtained. Can contain liquid. On the other hand, when the liquid phase supply valve 56 is opened and air is introduced into the liquid phase portion, the liquid in the cleaning tank 3 can be shaken, thereby mixing the cleaning agent and the cleaning water, and the cleaning agent in a short time. Can be uniformly diffused in the wash water. Further, the air supplied to the liquid phase part rises in the liquid in the cleaning tank 3 and eventually reaches the gas phase part. By increasing the pressure in the gas phase portion, the same effect as when the gas phase air supply valve 53 is opened can be obtained. Specifically, when the article to be cleaned 2 is a tube, for example, a liquid can be put into the tube.

〈加温動作〉
加温動作は、洗浄槽3内の液体が加温目標温度(設定温度)になるまで、洗浄槽3内の液体を加温する。具体的には、第一給水弁24、第二給水弁25、第一給液弁34、第二給液弁38、液相給気弁56、洗浄槽排水弁59を閉じた状態で、洗浄槽電気ヒータ40を作動させればよい。
<Heating operation>
In the heating operation, the liquid in the cleaning tank 3 is heated until the liquid in the cleaning tank 3 reaches the target heating temperature (set temperature). Specifically, the first water supply valve 24, the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, the liquid phase air supply valve 56, and the cleaning tank drain valve 59 are closed and washed. The tank electric heater 40 may be operated.

加温動作中、減圧手段8を停止すると共に、気相給気弁53を開いた状態に維持する。あるいは、加温動作中、減圧手段8による減圧と、その後の気相給気手段9による復圧とを繰り返してもよい。これにより、被洗浄物2がたとえばチューブの場合、チューブ内の残留空気を膨張および圧縮し、チューブ内に液体を流動させて、チューブ内の洗浄を図ることができる。   During the warming operation, the decompression means 8 is stopped and the gas phase supply valve 53 is kept open. Alternatively, during the heating operation, the decompression by the decompression unit 8 and the subsequent return pressure by the gas-phase air supply unit 9 may be repeated. Thereby, when the to-be-cleaned object 2 is a tube, for example, the residual air in a tube is expanded and compressed, a liquid can be flowed in a tube, and the inside of a tube can be wash | cleaned.

あるいは、加温動作中、減圧手段8による減圧と、その後の液相給気手段10による復圧とを繰り返してもよい。これにより、被洗浄物2がたとえば鉗子の場合、蒸気や空気の溜まる箇所がなくても、洗浄槽3内の液体中に気体を吹き込んで、洗浄槽3内の液体を揺動させることにより、被洗浄物2の洗浄を図ることができる。また、洗浄槽3内の液体を揺らすことで、液体の温度ムラを防止することもできる。   Alternatively, during the heating operation, the decompression by the decompression unit 8 and the subsequent return pressure by the liquid phase air supply unit 10 may be repeated. Thereby, in the case where the object to be cleaned 2 is, for example, forceps, even if there is no place where steam or air accumulates, by blowing a gas into the liquid in the cleaning tank 3 and swinging the liquid in the cleaning tank 3, The object to be cleaned 2 can be cleaned. In addition, by shaking the liquid in the cleaning tank 3, it is possible to prevent liquid temperature unevenness.

加温動作中、洗浄槽液温センサ13により洗浄槽3内の液体の温度を監視して、洗浄槽3内の液体が加温目標温度になれば、洗浄槽電気ヒータ40を停止させて加温動作を終了する。但し、引き続いて保温動作を実施する場合には、そのまま保温動作へ移行してもよい。   During the heating operation, the temperature of the liquid in the cleaning tank 3 is monitored by the cleaning tank liquid temperature sensor 13, and when the liquid in the cleaning tank 3 reaches the heating target temperature, the cleaning tank electric heater 40 is stopped and heated. End temperature operation. However, when the heat retaining operation is subsequently performed, the operation may be shifted to the heat retaining operation as it is.

〈保温動作〉
保温動作は、加温動作で洗浄槽3内の液体を加温目標温度まで昇温した後、その加温目標温度に液体を設定保温時間だけ保持する。具体的には、第一給水弁24、第二給水弁25、第一給液弁34、第二給液弁38、洗浄槽排水弁59を閉じた状態で、洗浄槽液温センサ13による検出温度を加温目標温度に維持するように、洗浄槽電気ヒータ40への通電の有無を制御する。
<Insulation operation>
In the warming operation, after the liquid in the cleaning tank 3 is heated to the warming target temperature by the warming operation, the liquid is held at the warming target temperature for the set warming time. Specifically, detection by the cleaning tank liquid temperature sensor 13 with the first water supply valve 24, the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, and the cleaning tank drain valve 59 closed. The presence / absence of energization of the washing tank electric heater 40 is controlled so as to maintain the temperature at the heating target temperature.

保温動作中、減圧手段8による減圧と、その後の液相給気手段10による復圧とを繰り返してもよい。このような制御を液相給気パルス制御ということにする。この場合、気相給気弁53は閉じた状態に維持される。あるいは、保温動作中、減圧手段8を停止すると共に、気相給気弁53を開いた状態に維持してもよい。この場合、液相給気弁56は閉じた状態に維持される。   During the heat retaining operation, the decompression by the decompression unit 8 and the subsequent return pressure by the liquid phase air supply unit 10 may be repeated. Such control is referred to as liquid phase air supply pulse control. In this case, the gas phase supply valve 53 is maintained in a closed state. Alternatively, during the heat retaining operation, the decompression means 8 may be stopped and the gas phase supply valve 53 may be kept open. In this case, the liquid phase supply valve 56 is maintained in a closed state.

保温動作中に液相給気パルス制御を行う場合について、さらに詳細に説明する。この場合、洗浄槽3内の液体を沸騰させるかその直前まで洗浄槽3内を減圧した状態で、液相給気弁56を開いて、被洗浄物2よりも下方から洗浄槽3内の液体中に気体を導入して、液体を沸騰させつつ被洗浄物2の洗浄が図られる。   The case where the liquid phase air supply pulse control is performed during the heat retaining operation will be described in more detail. In this case, the liquid in the cleaning tank 3 is opened from below the object to be cleaned 2 by opening the liquid-phase air supply valve 56 while boiling the liquid in the cleaning tank 3 or reducing the pressure in the cleaning tank 3 until just before that. The object to be cleaned 2 is cleaned while boiling the liquid by introducing gas therein.

すなわち、減圧手段8により洗浄槽3内の気相部の圧力を洗浄槽3内の液体の蒸気圧以下またはその直前まで下げた状態で、液相給気手段10により、被洗浄物2よりも下方から洗浄槽3内の液体中に気体を導入する。たとえば、図3の部分拡大図(工程f)に示すように、洗浄槽3内を減圧して、洗浄槽液温センサ13により検出される液温が所定温度(加温目標温度からたとえば0.5℃低い温度)まで下がると、液相給気弁56を開けばよい。これにより、洗浄槽3内の液体を沸騰、しかも激しく沸騰させることができ、被洗浄物2の洗浄を図ることができる。このような所定までの減圧と、その減圧により沸騰可能状態の液体中への気体導入による突沸の誘発とが繰り返される。液相給気パルス制御における洗浄槽3内の復圧時、減圧手段8は、作動を停止してもよいし、作動を継続してもよい。   That is, in a state where the pressure of the gas phase portion in the cleaning tank 3 is lowered to a pressure equal to or lower than the vapor pressure of the liquid in the cleaning tank 3 by the decompression means 8, the liquid phase air supply means 10 A gas is introduced into the liquid in the cleaning tank 3 from below. For example, as shown in the partial enlarged view of FIG. 3 (step f), the inside of the cleaning tank 3 is decompressed, and the liquid temperature detected by the cleaning tank liquid temperature sensor 13 is set to a predetermined temperature (for example, 0. When the temperature drops to a temperature lower by 5 ° C., the liquid phase supply valve 56 may be opened. As a result, the liquid in the cleaning tank 3 can be boiled and boiled vigorously, and the object to be cleaned 2 can be cleaned. Such depressurization up to a predetermined level and the induction of bumping by the introduction of a gas into the liquid in a boiling possible state by the depressurization are repeated. When the pressure in the cleaning tank 3 is restored in the liquid phase air supply pulse control, the decompression unit 8 may stop the operation or may continue the operation.

ところで、洗浄槽3内の液体を沸騰可能状態とするには、基本的には、洗浄槽3内の気相部の圧力を洗浄槽3内の液体の蒸気圧以下とする必要がある。但し、実際には、洗浄槽3内の液体の蒸気圧よりわずかに高い圧力でも、液体の一部に過熱した部分が存在することで、液体中に気体を導入することによって沸騰が起こる場合がある。そこで、洗浄槽3内の気相部の圧力を洗浄槽3内の液体の蒸気圧以下または場合によりその直前まで下げた状態として、液体中に気体を導入すればよい。   By the way, in order to make the liquid in the cleaning tank 3 boilable, it is basically necessary to set the pressure of the gas phase part in the cleaning tank 3 to be equal to or lower than the vapor pressure of the liquid in the cleaning tank 3. However, in reality, even if the pressure is slightly higher than the vapor pressure of the liquid in the cleaning tank 3, there is a case where boiling occurs due to the introduction of gas into the liquid due to the presence of a superheated part in the liquid. is there. Therefore, the gas may be introduced into the liquid by setting the pressure in the gas phase portion in the cleaning tank 3 to be equal to or lower than the vapor pressure of the liquid in the cleaning tank 3 or in some cases just before that.

洗浄槽3内の液体が加温目標温度になってから設定保温時間経過すると、洗浄槽電気ヒータ40を停止して、保温動作を終了する。被洗浄物2がたとえばチューブの場合、チューブ内の液温の上昇はチューブ外よりも遅れるが、保温動作を実行することで、チューブ内外の液温を一定に保持することができる。また、液相給気パルス制御を併用することで、洗浄液の突沸を利用して、洗浄槽3内の液体をムラなく加温目標温度にすることができる。   When the set heat retention time has elapsed after the liquid in the cleaning tank 3 reaches the warming target temperature, the cleaning tank electric heater 40 is stopped and the heat retaining operation is terminated. When the object to be cleaned 2 is, for example, a tube, the rise in the liquid temperature in the tube is delayed from the outside of the tube. However, by performing the heat retaining operation, the liquid temperature inside and outside the tube can be kept constant. Further, by using the liquid-phase air supply pulse control together, the liquid in the cleaning tank 3 can be set to the heating target temperature without unevenness by utilizing the bumping of the cleaning liquid.

〈冷却動作〉
冷却動作は、所定の終了条件を満たすまで、洗浄槽3内を減圧し、洗浄槽3内の液体を冷却する。具体的には、第一給水弁24、第二給水弁25、第一給液弁34、第二給液弁38、液相給気弁56、洗浄槽排水弁59を閉じると共に、洗浄槽電気ヒータ40を停止した状態で、減圧手段8を作動させればよい。
<Cooling operation>
The cooling operation depressurizes the cleaning tank 3 and cools the liquid in the cleaning tank 3 until a predetermined end condition is satisfied. Specifically, the first water supply valve 24, the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, the liquid phase air supply valve 56, and the cleaning tank drain valve 59 are closed and the cleaning tank electric What is necessary is just to operate the decompression means 8 in a state where the heater 40 is stopped.

前記終了条件としては、洗浄槽3内の液体が冷却目標温度になるまでとされる。但し、洗浄槽3内が目標圧力になるまでとしたり、目標時間が経過するまでとしたりしてもよい。   The termination condition is that the liquid in the cleaning tank 3 reaches the cooling target temperature. However, it may be until the inside of the cleaning tank 3 reaches the target pressure or until the target time elapses.

冷却動作中、気相給気パルス制御を行うのがよい。気相給気パルス制御を伴う冷却動作では、洗浄槽3内の液体を沸騰させ続けるように洗浄槽3内の減圧を継続し、この間、所定タイミングで、液体の沸騰が止むまで、洗浄槽3内を瞬時に一時的に復圧することが繰り返される。この復圧は、液体の沸騰が止む圧力までなされる。また、瞬時の復圧は、電磁弁からなる気相給気弁53を一気に開けることでなされる。この復圧時にも、減圧手段8は作動させたままでよい。気相給気弁53を開けて洗浄槽3内を復圧して、液体の沸騰を中断させた後は、気相給気弁53を再び閉じて、洗浄槽3内の減圧とそれによる液体の沸騰が図られる。   During the cooling operation, vapor phase air supply pulse control is preferably performed. In the cooling operation with the gas-phase air supply pulse control, the pressure in the cleaning tank 3 is continuously reduced so that the liquid in the cleaning tank 3 continues to boil, and during this time, until the liquid stops boiling at a predetermined timing. The inside of the inside is instantaneously and temporarily restored. This return pressure is performed up to a pressure at which the boiling of the liquid stops. Instantaneous return pressure is made by opening the gas-phase supply valve 53 made of an electromagnetic valve at a stroke. Even during the return pressure, the decompression means 8 may remain operated. After the gas-phase air supply valve 53 is opened and the pressure in the cleaning tank 3 is restored to stop the boiling of the liquid, the gas-phase air supply valve 53 is closed again to reduce the pressure in the cleaning tank 3 and the resulting liquid. Boiling is achieved.

前記所定タイミングとしては、洗浄槽液温センサ13に基づき洗浄槽3内の液体の温度を監視して、その温度が所定温度ずつ下がるたびとされる。但し、圧力センサ12に基づき洗浄槽3内の圧力を監視して、その圧力が所定圧力ずつ下がるたびとしてもよい。あるいは、洗浄槽3内の気相部に温度センサを設け、この温度センサに基づき洗浄槽3内の気相部の温度を監視して、その温度が所定温度ずつ下がるたびとしてもよい。   As the predetermined timing, the temperature of the liquid in the cleaning tank 3 is monitored based on the cleaning tank liquid temperature sensor 13, and the temperature is lowered every predetermined temperature. However, the pressure in the cleaning tank 3 may be monitored based on the pressure sensor 12 and the pressure may be decreased every predetermined pressure. Alternatively, a temperature sensor may be provided in the gas phase part in the cleaning tank 3, and the temperature of the gas phase part in the cleaning tank 3 may be monitored based on this temperature sensor, and the temperature may be lowered by a predetermined temperature.

このように、気相給気パルス制御を伴う冷却動作では、洗浄槽3内を減圧して液体を沸騰させ、この沸騰中に、洗浄槽3内を瞬時に一時的に復圧して、液体の沸騰を一気に止めることが繰り返される。従って、復圧時、それまでの沸騰により液中に生じていた水蒸気の気泡は、瞬時に凝縮することになる。この凝縮時の圧力波や圧力差で、洗浄槽3内の液体が攪拌および移送され、被洗浄物2の洗浄が図られる。また、被洗浄物2が管や穴を有する場合、洗浄槽3内の減圧により、被洗浄物2の管内や穴内には蒸気溜まりが生じるが、洗浄槽3内の復圧により、そのような蒸気溜まりが瞬時に消滅する。従って、被洗浄物2の管内や穴内に液体を激しく出入りさせることができ、それにより被洗浄物2の洗浄が図られる。   As described above, in the cooling operation with the gas-phase air supply pulse control, the inside of the cleaning tank 3 is decompressed to boil the liquid, and during this boiling, the inside of the cleaning tank 3 is instantaneously and temporarily re-pressured. Repeatedly stopping boiling at once. Therefore, when the pressure is restored, the bubbles of water vapor generated in the liquid due to boiling until then are condensed instantly. The liquid in the cleaning tank 3 is agitated and transferred by the pressure wave and pressure difference during the condensation, and the object to be cleaned 2 is cleaned. In addition, when the object to be cleaned 2 has a pipe or a hole, a vapor accumulation occurs in the pipe or the hole of the object to be cleaned 2 due to the decompression in the cleaning tank 3. The vapor pool disappears instantly. Accordingly, the liquid can be vigorously moved in and out of the tube or hole of the object to be cleaned 2, thereby cleaning the object to be cleaned 2.

このような処理は、前記終了条件が満たされるまでなされる。典型的には、前述したとおり、洗浄槽3内の液体が冷却目標温度になるまで行われる。前記終了条件が満たされると、減圧手段8の作動を停止して、冷却動作を終了する。   Such processing is performed until the end condition is satisfied. Typically, as above-mentioned, it is performed until the liquid in the washing tank 3 reaches cooling target temperature. When the termination condition is satisfied, the operation of the decompression means 8 is stopped and the cooling operation is terminated.

〈復圧動作〉
復圧動作は、洗浄槽3内を復圧目標圧力まで復圧する。具体的には、第一給水弁24、第二給水弁25、第一給液弁34、第二給液弁38、液相給気弁56、洗浄槽排水弁59を閉じると共に、洗浄槽電気ヒータ40および減圧手段8を停止した状態で、気相給気弁53を開けばよい。洗浄槽3内が復圧目標圧力まで復圧されると、復圧動作を終了する。
<Return pressure operation>
In the return pressure operation, the inside of the cleaning tank 3 is returned to the return pressure target pressure. Specifically, the first water supply valve 24, the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, the liquid phase air supply valve 56, and the cleaning tank drain valve 59 are closed and the cleaning tank electrical The vapor supply valve 53 may be opened while the heater 40 and the decompression means 8 are stopped. When the inside of the cleaning tank 3 is returned to the return pressure target pressure, the return pressure operation is terminated.

〈排水動作〉
排水動作は、洗浄槽3内の液体を排出する。具体的には、第一給水弁24、第二給水弁25、第一給液弁34、第二給液弁38、液相給気弁56を閉じる一方、気相給気弁53を開くと共に、洗浄槽電気ヒータ40および減圧手段8を停止した状態で、洗浄槽排水弁59を開けばよい。これにより、洗浄槽3内の液体が、洗浄槽3外へ排出される。洗浄槽3内の液体が完全に排出されたことを洗浄槽液位検出器で検知すると、洗浄槽排水弁59を閉じて、排水動作を終了する。
<Draining action>
In the draining operation, the liquid in the cleaning tank 3 is discharged. Specifically, the first water supply valve 24, the second water supply valve 25, the first liquid supply valve 34, the second liquid supply valve 38, and the liquid phase air supply valve 56 are closed while the gas phase air supply valve 53 is opened. The washing tank drain valve 59 may be opened while the washing tank electric heater 40 and the decompression means 8 are stopped. Thereby, the liquid in the cleaning tank 3 is discharged out of the cleaning tank 3. When the washing tank liquid level detector detects that the liquid in the washing tank 3 has been completely discharged, the washing tank drain valve 59 is closed and the draining operation is terminated.

《各濯ぎ工程S4〜S6》
各濯ぎ工程S4〜S6では、液切り動作、給水動作、濯ぎ剤投入動作、加温動作、保温動作、減圧動作、復圧動作および排水動作の内、選択された動作を順次に実行する。この内、液切り動作、給水動作、加温動作、保温動作、減圧動作、復圧動作および排水動作は、上述した各洗浄工程S2〜S3におけるものと同様であるから、その説明を省略する。但し、加温目標温度および設定保温時間の他、各給気パルス制御の有無、各給気パルス制御をどのような圧力や温度で行うかなどは、各工程の各動作に応じて適宜に設定される。
<< Each rinsing step S4 to S6 >>
In each of the rinsing steps S4 to S6, a selected operation among the liquid draining operation, the water supply operation, the rinsing agent charging operation, the warming operation, the heat retaining operation, the pressure reducing operation, the decompression operation, and the draining operation is sequentially executed. Among these, the liquid draining operation, the water supply operation, the warming operation, the heat retaining operation, the pressure reducing operation, the pressure-reducing operation, and the draining operation are the same as those in the above-described cleaning steps S2 to S3. However, in addition to the target heating temperature and the set heat retention time, the presence / absence of each air supply pulse control, the pressure and temperature at which each air supply pulse control is performed, etc. are appropriately set according to the operation of each process. Is done.

また、濯ぎ工程S4〜S6における給水動作では、第一給水弁24に代えて第二給水弁25を開くことで、洗浄槽3内へは濯ぎ水が供給される。この際、三方電磁弁27は、共通給水路26と洗浄槽給水路28とを連通させる。また、濯ぎ工程S4〜S6における給水動作でも、予熱タンク4において既に熱水(温水を含む)が用意されている場合には、送水手段15による予熱タンク4からの熱水に、給水手段5による水を混ぜて用いることができる。   In the water supply operation in the rinsing steps S <b> 4 to S <b> 6, rinsing water is supplied into the cleaning tank 3 by opening the second water supply valve 25 instead of the first water supply valve 24. At this time, the three-way solenoid valve 27 causes the common water supply path 26 and the cleaning tank water supply path 28 to communicate with each other. Further, even in the water supply operation in the rinsing steps S4 to S6, when hot water (including hot water) is already prepared in the preheating tank 4, the hot water from the preheating tank 4 by the water supply means 15 is added to the hot water by the water supply means 5. Can be mixed with water.

〈濯ぎ剤投入動作〉
濯ぎ剤投入動作は、上述した各洗浄工程S2,S3における洗浄剤投入動作に対応するものであり、異なる点は、洗浄槽3内へ供給される液が、洗浄剤ではなく濯ぎ剤である点にある。つまり、洗浄工程S2〜S3における洗浄剤投入動作では、減圧手段8により洗浄槽3内を減圧後、第一給液弁34を開いて洗浄剤を洗浄槽3へ供給したが、濯ぎ工程S4〜S6における濯ぎ剤投入動作では、減圧手段8により洗浄槽3内を減圧後、第二給液弁38を開いて濯ぎ剤を洗浄槽3へ供給する。このようにして、洗浄槽3内へ濯ぎ剤を引き込むことで、洗浄槽3内の濯ぎ水に濯ぎ剤を混入して濯ぎ液とする。そして、設定時間だけ第二給液弁38を開くなどして、所望量の濯ぎ剤を洗浄槽3内へ供給した後、第二給液弁38を閉じる一方、気相給気弁53または液相給気弁56を開けて、濯ぎ剤投入動作を終了する。
<Rinsing agent charging operation>
The rinsing agent charging operation corresponds to the cleaning agent charging operation in each of the cleaning steps S2 and S3 described above. The difference is that the liquid supplied into the cleaning tank 3 is not the cleaning agent but the rinsing agent. It is in. That is, in the cleaning agent charging operation in the cleaning steps S2 to S3, after the pressure in the cleaning tank 3 is reduced by the pressure reducing means 8, the first liquid supply valve 34 is opened and the cleaning agent is supplied to the cleaning tank 3. In the rinsing agent charging operation in S <b> 6, after the pressure in the cleaning tank 3 is reduced by the pressure reducing means 8, the second liquid supply valve 38 is opened to supply the rinse agent to the cleaning tank 3. In this manner, the rinsing agent is drawn into the washing tank 3, so that the rinsing agent is mixed into the rinsing water in the washing tank 3 to obtain a rinsing liquid. Then, after supplying a desired amount of the rinsing agent into the cleaning tank 3 by opening the second liquid supply valve 38 for a set time, the second liquid supply valve 38 is closed, while the gas phase air supply valve 53 or the liquid is supplied. The phase supply valve 56 is opened and the rinsing agent charging operation is terminated.

《液切り工程S7》
液切り工程S7は、前記予洗工程S1、前記各洗浄工程S2〜S3および前記各濯ぎ工程S4〜S6における液切り動作およびその後の復圧動作に対応するものである。つまり、液切り工程S7における液切り動作は、洗浄工程S2〜S3などにおける液切り動作に相当し、液切り工程S7における復圧動作は、洗浄工程S2〜S3などにおける復圧動作に相当する。従って、液切り工程S7では、洗浄槽3内が空気で満たされた状態で、洗浄槽3内を減圧した後、洗浄槽3内を大気圧まで復圧する。
<< Liquid draining step S7 >>
The liquid draining step S7 corresponds to the liquid draining operation in the pre-washing step S1, the cleaning steps S2 to S3, and the rinsing steps S4 to S6, and the subsequent pressure recovery operation. That is, the liquid draining operation in the liquid draining step S7 corresponds to the liquid draining operation in the cleaning steps S2 to S3, and the pressure recovery operation in the liquid draining step S7 corresponds to a pressure recovery operation in the cleaning steps S2 to S3. Therefore, in the liquid draining step S7, after the pressure in the cleaning tank 3 is reduced while the cleaning tank 3 is filled with air, the pressure in the cleaning tank 3 is restored to atmospheric pressure.

洗浄槽3では、以上のとおり、予洗工程S1、第一洗浄工程S2、第二洗浄工程S3、第一濯ぎ工程S4、第二濯ぎ工程S5、第三濯ぎ工程S6および液切り工程S7の内、選択された工程を順次に実行するが、その間、予熱タンク4では、洗浄槽3内の液体の次回の入れ替え用の液体の加温が行われる。たとえば、第二洗浄工程S3において排水動作を実行し、第一濯ぎ工程S4において給水動作を実行する場合には、第二洗浄工程S3(およびそれより前の工程が排水動作を伴わない場合にはその工程も含む)において、予熱タンク4では第一濯ぎ工程S4に用いる濯ぎ水の加温が図られる。   In the washing tank 3, as described above, among the pre-washing step S1, the first washing step S2, the second washing step S3, the first rinsing step S4, the second rinsing step S5, the third rinsing step S6 and the liquid draining step S7, The selected steps are sequentially executed. In the meantime, in the preheating tank 4, the liquid for the next replacement of the liquid in the cleaning tank 3 is heated. For example, when the draining operation is executed in the second cleaning step S3 and the water supply operation is executed in the first rinsing step S4, the second cleaning step S3 (and when the previous step is not accompanied by the draining operation). In the preheating tank 4, the rinsing water used in the first rinsing step S4 is heated.

具体的には、予熱タンク4では、給水動作、加温動作、送水動作および所望により排水動作が、順に行われる。また、これら一連の動作が所望により繰り返される。   Specifically, in the preheating tank 4, a water supply operation, a warming operation, a water supply operation, and a drainage operation are performed in order as desired. Moreover, a series of these operations are repeated as desired.

〈予熱タンク4への給水動作〉
予熱タンク4への給水動作では、給水手段5を用いて、予熱タンク4内へ水を供給する。給水手段5による予熱タンク4内への給水は、給湯弁65および予熱タンク排水弁67を閉じると共に、予熱タンク電気ヒータ62および送水ポンプ64を停止した状態で、第一給水弁24または第二給水弁25を開けばよい。この際、三方電磁弁27は、共通給水路26と予熱タンク給水路29とを連通させる。従って、第一給水弁24を開けば、予熱タンク4内へ洗浄水を供給することができ、第二給水弁25を開けば、予熱タンク4内へ濯ぎ水を供給することができる。
<Water supply operation to the preheating tank 4>
In the water supply operation to the preheating tank 4, water is supplied into the preheating tank 4 using the water supply means 5. The water supply means 5 supplies water into the preheating tank 4 with the hot water supply valve 65 and the preheating tank drain valve 67 closed, and with the preheating tank electric heater 62 and the water supply pump 64 stopped, the first water supply valve 24 or the second water supply water. The valve 25 may be opened. At this time, the three-way solenoid valve 27 causes the common water supply path 26 and the preheating tank water supply path 29 to communicate with each other. Therefore, if the first water supply valve 24 is opened, the cleaning water can be supplied into the preheating tank 4, and if the second water supply valve 25 is opened, the rinsing water can be supplied into the preheating tank 4.

予熱タンク4内にいずれの種類の水を貯留するかは、洗浄槽3内の液体の次回の入れ替え用の液体の種類に応じて決められる。たとえば、洗浄槽3内で被洗浄物2を洗浄液で洗浄後、洗浄槽3内の液体を濯ぎ液に入れ替えて、被洗浄物2を濯ぎしようとする場合、洗浄槽3内において被洗浄物2を洗浄中には、予熱タンク4において濯ぎ水を貯留してその加温が図られる。また、その後、洗浄槽3から濯ぎ液を排水して、洗浄槽3内の被洗浄物2を入れ替えた後、その新たな被洗浄物2を洗浄液で洗浄しようとする場合には、被洗浄物2の濯ぎ中には、予熱タンク4において次回の被洗浄物2の洗浄用の洗浄水を貯留してその加温が図られる。つまり、洗浄槽3において被洗浄物2を入れ替えつつ一連の運転(典型的には洗浄から濯ぎの一連の動作)を複数回行う場合には、次回の運転に用いる液体を、その直前の運転にて加温しておくこともできる。なお、予熱タンク4への給水動作は、洗浄槽3への給水動作の終了後すぐに行うのが好ましい。   Which type of water is stored in the preheating tank 4 is determined according to the type of liquid for the next replacement of the liquid in the cleaning tank 3. For example, when the object to be cleaned 2 is cleaned with the cleaning liquid in the cleaning tank 3 and then the liquid in the cleaning tank 3 is replaced with the rinsing liquid and the object to be cleaned 2 is to be rinsed, the object to be cleaned 2 in the cleaning tank 3 During the cleaning, the rinsing water is stored in the preheating tank 4 and is warmed. In addition, after the rinsing liquid is drained from the cleaning tank 3 and the object to be cleaned 2 in the cleaning tank 3 is replaced, the new object to be cleaned 2 is to be cleaned with the cleaning liquid. During the rinsing of 2, the preheating tank 4 stores cleaning water for the next cleaning of the article 2 to be heated. That is, when a series of operations (typically a series of operations from washing to rinsing) is performed a plurality of times while replacing the object to be cleaned 2 in the washing tank 3, the liquid used for the next operation is changed to the operation just before that. Can also be warmed. The water supply operation to the preheating tank 4 is preferably performed immediately after the water supply operation to the cleaning tank 3 is completed.

〈予熱タンク4内の加温動作〉
予熱タンク4内の加温動作では、予熱タンク4内の液体が予熱目標温度になるまで、予熱タンク4内の液体を加温する。具体的には、給湯弁65および予熱タンク排水弁67を閉じると共に、送水ポンプ64を停止した状態で、予熱タンク電気ヒータ62を作動させればよい。但し、予熱タンク電気ヒータ62は、洗浄槽電気ヒータ40の停止中にのみ作動するよう制御される。
<Heating operation in the preheating tank 4>
In the heating operation in the preheating tank 4, the liquid in the preheating tank 4 is heated until the liquid in the preheating tank 4 reaches the preheating target temperature. Specifically, the preheating tank electric heater 62 may be operated while the hot water supply valve 65 and the preheating tank drain valve 67 are closed and the water supply pump 64 is stopped. However, the preheating tank electric heater 62 is controlled to operate only when the washing tank electric heater 40 is stopped.

ところで、予熱目標温度は、洗浄槽3における加温目標温度よりも高い温度に設定するのがよい。そのように設定しても、予熱タンク4の容量は洗浄槽3よりも小さい上、洗浄槽3においては、予熱タンク4からの熱水に給水手段5からの水を混ぜて用いるので、洗浄槽3における給水動作の終了時点で、洗浄槽3内の貯留液の温度が加温目標温度を超えることはない。   By the way, the preheating target temperature is preferably set to a temperature higher than the heating target temperature in the cleaning tank 3. Even if it sets in that way, since the capacity | capacitance of the preheating tank 4 is smaller than the washing tank 3, in the washing tank 3, since the water from the water supply means 5 is mixed with the hot water from the preheating tank 4, it is used for the washing tank 3, the temperature of the stored liquid in the cleaning tank 3 does not exceed the target heating temperature.

また、予熱タンク4内の加温動作において、予熱タンク4内の液体が必ずしも予熱目標温度まで上がらなくても、洗浄槽3内へ移した後、前述したように加温動作を実行することで不都合はない。つまり、予熱タンク4からの熱水の温度や給水量、給水手段5からの水の温度や給水量に拘わらず、洗浄槽3内の加温動作により、洗浄槽3内の貯留液の温度を必ず加温目標温度にして用いることができる。これにより、各給気パルス制御の効果を安定して発揮させることができる。   Further, in the heating operation in the preheating tank 4, even if the liquid in the preheating tank 4 does not necessarily rise to the preheating target temperature, the liquid is transferred into the cleaning tank 3 and then the heating operation is executed as described above. There is no inconvenience. That is, regardless of the temperature and amount of hot water from the preheating tank 4 and the temperature and amount of water from the water supply means 5, the temperature of the stored liquid in the cleaning tank 3 is set by the heating operation in the cleaning tank 3. It can always be used at the heating target temperature. Thereby, the effect of each air supply pulse control can be exhibited stably.

一方、予熱タンク4内の加温動作において、予熱タンク4内の液体が予熱目標温度に達した後は、その温度を維持するように、予熱タンク液温センサ17の検出温度に基づき予熱タンク電気ヒータ62への通電を制御して、液温を保持すればよい。   On the other hand, in the heating operation in the preheating tank 4, after the liquid in the preheating tank 4 reaches the preheating target temperature, the preheating tank electric power is based on the temperature detected by the preheating tank liquid temperature sensor 17 so that the temperature is maintained. What is necessary is just to control energization to the heater 62 and hold | maintain a liquid temperature.

〈予熱タンク4から洗浄槽3への送水動作〉
予熱タンク4から洗浄槽3への送水動作では、予熱タンク排水弁67を閉じる一方、送水ポンプ64を作動させた状態で、給湯弁65を開けばよい。これにより、予熱タンク4内の液体を洗浄槽3内へ移すことができる。この送水動作は、前述したように、洗浄槽3における給水動作時に行われる。
<Water supply operation from the preheating tank 4 to the washing tank 3>
In the water supply operation from the preheating tank 4 to the cleaning tank 3, the hot water supply valve 65 may be opened while the preheating tank drain valve 67 is closed and the water supply pump 64 is operated. Thereby, the liquid in the preheating tank 4 can be moved into the washing tank 3. This water supply operation is performed during the water supply operation in the cleaning tank 3 as described above.

〈予熱タンク4からの排水動作〉
予熱タンク4からの排水動作では、給湯弁65を閉じると共に、予熱タンク電気ヒータ62および送水ポンプ64を停止した状態で、予熱タンク排水弁67を開けばよい。予熱タンク4から洗浄槽3への送水動作の終了後、再び次回の液体を予熱タンク4に貯留して加温することが可能であるが、予熱タンク4へ貯留する液体の種類が変わる場合には、送水動作の終了後に排水動作を行ってから、再び給水動作が行われる。一方、液体の種類が変わらない場合には、送水動作の終了後に排水動作を行わずに、給水動作を行ってもよい。
<Draining operation from preheating tank 4>
In the draining operation from the preheating tank 4, the preheating tank drain valve 67 may be opened while the hot water supply valve 65 is closed and the preheating tank electric heater 62 and the water supply pump 64 are stopped. After the water feeding operation from the preheating tank 4 to the washing tank 3 is completed, the next liquid can be stored again in the preheating tank 4 and heated. However, when the type of liquid stored in the preheating tank 4 changes. The water supply operation is performed again after the drainage operation is performed after the water supply operation is completed. On the other hand, when the type of the liquid does not change, the water supply operation may be performed without performing the drainage operation after the water supply operation is completed.

図3は、本実施例の洗浄装置1の運転方法の一例を示す図であり、洗浄槽3内の液温(縦軸)と経過時間(横軸)との関係を示している。また、その下部に示す(A)は洗浄槽電気ヒータ40のタイムチャートであり、(B)は予熱タンク電気ヒータ62のタイムチャートである。   FIG. 3 is a diagram illustrating an example of a method of operating the cleaning device 1 of the present embodiment, and illustrates a relationship between the liquid temperature (vertical axis) and the elapsed time (horizontal axis) in the cleaning tank 3. Moreover, (A) shown in the lower part is a time chart of the washing tank electric heater 40, and (B) is a time chart of the preheating tank electric heater 62.

この例では、洗浄槽3について、第一洗浄工程S2、第二洗浄工程S3、第一濯ぎ工程S4および第二濯ぎ工程S5を選択した例を示している。そして、第一洗浄工程S2では、給水動作、洗浄剤投入動作、加温動作、保温動作、冷却動作、復圧動作が選択されている。また、第二洗浄工程S3では、加温動作、保温動作、冷却動作、復圧動作、排水動作が選択されている。また、第一濯ぎ工程S4では、給水動作、加温動作、保温動作、冷却動作、復圧動作、排水動作が選択されている。さらに、第二濯ぎ工程S5では、給水動作、濯ぎ剤投入動作、加温動作、保温動作、冷却動作、復圧動作、排水動作が選択されている。   This example shows an example in which the first washing step S2, the second washing step S3, the first rinsing step S4, and the second rinsing step S5 are selected for the washing tank 3. In the first cleaning step S2, a water supply operation, a cleaning agent charging operation, a warming operation, a heat retaining operation, a cooling operation, and a return pressure operation are selected. In the second cleaning step S3, a warming operation, a heat retaining operation, a cooling operation, a return pressure operation, and a draining operation are selected. In the first rinsing step S4, a water supply operation, a warming operation, a heat retaining operation, a cooling operation, a return pressure operation, and a draining operation are selected. Furthermore, in the second rinsing step S5, a water supply operation, a rinse agent charging operation, a warming operation, a heat retaining operation, a cooling operation, a return pressure operation, and a draining operation are selected.

但し、この運転方法は、あくまでも一例であって、適宜に変更可能なことは言うまでもない。すなわち、各洗浄工程(S2,S3)や各濯ぎ工程(S4〜S6)などの内からどの工程を選択して実行するか、また、選択した工程中でどの動作を選択して実行するか、および、その選択された動作をどのような内容(たとえば温度、圧力、時間など)で実行するかは適宜に変更可能である。   However, this operation method is merely an example, and needless to say, it can be changed as appropriate. That is, which process is selected and executed from each of the cleaning processes (S2, S3) and each rinsing process (S4 to S6), and which operation is selected and executed in the selected process, The content (for example, temperature, pressure, time, etc.) of the selected operation can be changed as appropriate.

図3の場合について、具体的に説明すると、第一洗浄工程S2の給水動作aと洗浄剤投入動作とにより、洗浄槽3内に洗浄液を貯留した後、加温動作bおよび保温動作cにより、洗浄液を第一加温目標温度T1まで昇温して保持した後、冷却動作dを行った後、復圧動作により洗浄槽3内を大気圧まで復圧する。   The case of FIG. 3 will be specifically described. After storing the cleaning liquid in the cleaning tank 3 by the water supply operation a and the cleaning agent charging operation in the first cleaning step S2, the heating operation b and the heat retaining operation c After the temperature of the cleaning liquid is raised to the first heating target temperature T1 and held, the cooling operation d is performed, and then the pressure in the cleaning tank 3 is returned to atmospheric pressure by the pressure recovery operation.

その後、第二洗浄工程S3の加温動作eおよび保温動作fにより、洗浄液を第二加温目標温度T2まで昇温して保持した後、冷却動作gを行った後、復圧動作により洗浄槽3内を大気圧まで復圧して、排水動作hにより洗浄液を排出する。なお、図示例では、第二加温目標温度T2は第一加温目標温度T1よりも高く設定され、これにより消毒を兼ねた洗浄を図ることができる。   Thereafter, the temperature of the cleaning liquid is raised to the second warming target temperature T2 by the warming operation e and the warming operation f in the second cleaning step S3, and then the cooling operation g is performed. 3 is returned to atmospheric pressure, and the cleaning liquid is discharged by the drainage operation h. In the illustrated example, the second warming target temperature T2 is set to be higher than the first warming target temperature T1, and thus cleaning that also serves as disinfection can be achieved.

その後、第一濯ぎ工程S4の給水動作iにより、洗浄槽3内に濯ぎ水を貯留した後、加温動作jと保温動作kとにより、濯ぎ水を第三加温目標温度T3まで昇温して保持した後、冷却動作lを行った後、復圧動作により洗浄槽3内を大気圧まで復圧して、排水動作mにより濯ぎ水を排出する。   Thereafter, the rinsing water is stored in the washing tank 3 by the water supply operation i in the first rinsing step S4, and then the rinsing water is heated to the third heating target temperature T3 by the heating operation j and the heat retaining operation k. Then, after the cooling operation 1 is performed, the pressure in the cleaning tank 3 is restored to the atmospheric pressure by the decompression operation, and the rinsing water is discharged by the drain operation m.

その後、第二濯ぎ工程S5の給水動作nと濯ぎ剤投入動作とにより、洗浄槽3内に濯ぎ液を貯留した後、加温動作oと保温動作pとにより、濯ぎ液を第四加温目標温度T4まで昇温して保持した後、冷却動作qを行った後、復圧動作により洗浄槽3内を大気圧まで復圧して、排水動作rにより濯ぎ液を排出する。   Thereafter, the rinsing liquid is stored in the washing tank 3 by the water supply operation n and the rinsing agent charging operation in the second rinsing step S5, and then the rinsing liquid is set to the fourth heating target by the heating operation o and the heat retaining operation p. After the temperature is raised to T4 and held, the cooling operation q is performed, and then the pressure in the cleaning tank 3 is restored to atmospheric pressure by the re-pressure operation, and the rinsing liquid is discharged by the drain operation r.

これら一連の工程(S2〜S5)における各保温動作c,f,k,pでは、部分拡大して示すように、液相給気パルス制御が行われる。また、各冷却動作d,g,l,qでは、気相給気パルス制御が行われる。このようにして、被洗浄物2の洗浄および濯ぎが効果的に図られる。   In each of the heat retaining operations c, f, k, and p in the series of steps (S2 to S5), liquid phase air supply pulse control is performed as shown in a partially enlarged manner. In each cooling operation d, g, l, and q, gas-phase air supply pulse control is performed. In this way, the object to be cleaned 2 can be effectively cleaned and rinsed.

この例では、洗浄槽3内には、第一洗浄工程S2の給水動作aおよび洗浄剤投入動作において洗浄液が貯留され、その貯留液は第二洗浄工程S3の排水動作で排水される。その後、洗浄槽3内には、第一濯ぎ工程S4の給水動作iにおいて濯ぎ水が貯留され、その貯留液は同工程の排水動作mで排水される。その後、洗浄槽3内には、第二濯ぎ工程S5の給水動作nおよび濯ぎ剤投入動作において濯ぎ液が貯留され、その貯留液は同工程の排水動作rで排水される。また、第一洗浄工程S2から第二濯ぎ工程S5までの一連の動作を終了した後、洗浄槽3内の被洗浄物2を入れ替えて再び洗浄などを行うこともできる。   In this example, the cleaning liquid is stored in the cleaning tank 3 in the water supply operation a and the cleaning agent charging operation in the first cleaning step S2, and the stored liquid is drained in the draining operation in the second cleaning step S3. Thereafter, rinsing water is stored in the washing tank 3 in the water supply operation i of the first rinsing step S4, and the stored liquid is drained by the draining operation m of the same step. Thereafter, the rinsing liquid is stored in the washing tank 3 in the water supply operation n and the rinsing agent charging operation in the second rinsing step S5, and the stored liquid is discharged in the draining operation r in the same step. Moreover, after a series of operation | movement from 1st washing | cleaning process S2 to 2nd rinsing process S5 is complete | finished, the to-be-cleaned object 2 in the washing tank 3 can be replaced, and washing | cleaning etc. can be performed again.

この例では、第一洗浄工程S2の給水動作aの終了後、次回の給水(第一濯ぎ工程S4の給水動作i)に備えて、予熱タンク4では濯ぎ水が貯留されて加温される。この際、洗浄槽電気ヒータ40の停止中を利用して、予熱タンク電気ヒータ62を作動させて、予熱タンク4内の貯留液の加温が図られる。図3(A)に示すように、洗浄槽電気ヒータ40は、第一洗浄工程S2の加温動作bではオンされ、同工程の保温動作cではオンオフ制御され、同工程の冷却動作dおよび復圧動作ではオフされ、引き続いて実行される第二洗浄工程S3の加温動作eではオンされ、保温動作fではオンオフ制御され、同工程の冷却動作g、復圧動作および排水動作hではオフされる。従って、同図(B)に示すように、予熱タンク電気ヒータ62は、第一洗浄工程S2の冷却動作dおよび復圧動作や、第二洗浄工程S3の冷却動作g、復圧動作および排水動作h中にオンされて、予熱タンク4内の貯留水を加温する。また、これに加えて、第一洗浄工程S2や第二洗浄工程S3の各保温動作c,fにおいて、洗浄槽電気ヒータ40がオフとされている間だけ、予熱タンク電気ヒータ62をオンしてもよい。   In this example, the rinsing water is stored and heated in the preheating tank 4 in preparation for the next water supply (the water supply operation i of the first rinsing step S4) after the water supply operation a of the first cleaning step S2. At this time, the preheating tank electric heater 62 is operated while the washing tank electric heater 40 is stopped, and the stored liquid in the preheating tank 4 is heated. As shown in FIG. 3A, the washing tank electric heater 40 is turned on in the heating operation b in the first washing step S2, and is turned on / off in the heat retaining operation c in the first step, and the cooling operation d and the recovery operation in the same step are performed. It is turned off in the pressure operation, is turned on in the heating operation e of the second cleaning step S3 that is subsequently executed, is turned on / off in the heat retaining operation f, and is turned off in the cooling operation g, the pressure-reducing operation, and the drainage operation h in the same process. The Accordingly, as shown in FIG. 5B, the preheating tank electric heater 62 is operated by the cooling operation d and the return pressure operation in the first cleaning step S2, and the cooling operation g, the return pressure operation and the drainage operation in the second cleaning step S3. It is turned on during h to warm the stored water in the preheating tank 4. In addition to this, the preheating tank electric heater 62 is turned on only while the washing tank electric heater 40 is turned off in each of the heat retaining operations c and f of the first washing process S2 and the second washing process S3. Also good.

また、第一濯ぎ工程S4の給水動作i後、次回の給水(第二濯ぎ工程S5の給水動作n)に備えて、予熱タンク4では濯ぎ水が貯留されて加温される。この際も、洗浄槽電気ヒータ40の停止中を利用して、予熱タンク電気ヒータ62を作動させて、予熱タンク4内の貯留液の加温が図られる。図3(A)に示すように、洗浄槽電気ヒータ40は、第一濯ぎ工程S4の加温動作jではオンされ、同工程の保温動作kではオンオフ制御され、同工程の冷却動作l、復圧動作および排水動作mではオフされる。従って、同図(B)に示すように、予熱タンク電気ヒータ62は、第一濯ぎ工程S4の冷却動作l、復圧動作および排水動作m中にオンされて、予熱タンク4内の貯留水を加温する。また、これに加えて、第一濯ぎ工程S4の保温動作kにおいて、洗浄槽電気ヒータ40がオフとされている間だけ、予熱タンク電気ヒータ62をオンしてもよい。   In addition, after the water supply operation i in the first rinsing step S4, the rinsing water is stored and heated in the preheating tank 4 in preparation for the next water supply (the water supply operation n in the second rinsing step S5). Also at this time, the preheating tank electric heater 62 is operated by using the stoppage of the washing tank electric heater 40 to warm the stored liquid in the preheating tank 4. As shown in FIG. 3A, the washing tank electric heater 40 is turned on in the heating operation j in the first rinsing step S4 and is turned on / off in the heat retaining operation k in the first rinsing step S4. It is turned off in the pressure operation and the drain operation m. Therefore, as shown in FIG. 5B, the preheating tank electric heater 62 is turned on during the cooling operation l, the pressure recovery operation and the draining operation m in the first rinsing step S4, and the stored water in the preheating tank 4 is discharged. Warm up. In addition, in the heat retaining operation k of the first rinsing step S4, the preheating tank electric heater 62 may be turned on only while the cleaning tank electric heater 40 is turned off.

さらに、第一洗浄工程S2から第二濯ぎ工程S5までの一連の動作を終了した後、洗浄槽3内の被洗浄物2を入れ替えて再び洗浄などを行う場合には、予め制御器70に次の運転予約をしておくことで、次のような動作を行ってもよい。すなわち、第二濯ぎ工程S5の給水動作n後、次回の給水(第一洗浄工程S2の給水動作aなど)に備えて、予熱タンク4では洗浄水が貯留されて加温されてもよい。この際も、洗浄槽電気ヒータ40の停止中を利用して、予熱タンク電気ヒータ62を作動させて、予熱タンク4内の貯留液の加温が図られる。図3(A)に示すように、洗浄槽電気ヒータ40は、第二濯ぎ工程S5の加温動作oではオンされ、同工程の保温動作pではオンオフ制御され、同工程の冷却動作q、復圧動作および排水動作rではオフされる。従って、同図(B)に示すように、予熱タンク電気ヒータ62は、第二濯ぎ工程S5の冷却動作q、復圧動作および排水動作r中にオンされて、予熱タンク4内の貯留水を加温する。また、これに加えて、第二濯ぎ工程S5の保温動作pにおいて、洗浄槽電気ヒータ40がオフとされている間だけ、予熱タンク電気ヒータ62をオンしてもよい。   Further, after the series of operations from the first cleaning step S2 to the second rinsing step S5 is completed, when the object to be cleaned 2 in the cleaning tank 3 is replaced and cleaning is performed again, the controller 70 is previously connected. The following operation may be performed by making an operation reservation. That is, after the water supply operation n in the second rinsing step S5, the preheating tank 4 may store and wash the cleaning water in preparation for the next water supply (such as the water supply operation a in the first cleaning step S2). Also at this time, the preheating tank electric heater 62 is operated by using the stoppage of the washing tank electric heater 40 to warm the stored liquid in the preheating tank 4. As shown in FIG. 3 (A), the washing tank electric heater 40 is turned on in the heating operation o in the second rinsing step S5, and is turned on / off in the heat retaining operation p in the second step. It is turned off in the pressure operation and the drain operation r. Therefore, as shown in FIG. 5B, the preheating tank electric heater 62 is turned on during the cooling operation q, the recuperation operation and the draining operation r in the second rinsing step S5, and the stored water in the preheating tank 4 is discharged. Warm up. In addition, in the heat retaining operation p of the second rinsing step S5, the preheating tank electric heater 62 may be turned on only while the washing tank electric heater 40 is turned off.

このように、本実施例の洗浄装置1によれば、洗浄槽電気ヒータ40の停止中を利用して予熱タンク電気ヒータ62を作動させて、洗浄槽3内の液体の次回の入れ替え用の液体の加温を図ることができる。これにより、洗浄槽3において実施される各工程の加温動作の初期温度を上げることができ、洗浄装置1の運転時間の短縮を図ることができる。たとえば、図3の例で、第一洗浄工程S2から第二濯ぎ工程S5までの一連の動作を繰り返す場合には、第二濯ぎ工程S5で次回の第一洗浄工程S2用の洗浄水を予熱タンク4で加温しておけば、第一洗浄工程S2の初期液温を二点鎖線で示すように高めることができ、結果として加温工程bにおける加温時間の短縮を図り、ひいては運転時間の短縮を図ることができる。   Thus, according to the cleaning apparatus 1 of the present embodiment, the preheating tank electric heater 62 is operated while the cleaning tank electric heater 40 is stopped, and the liquid for the next replacement of the liquid in the cleaning tank 3 is used. Can be heated. Thereby, the initial temperature of the heating operation of each process performed in the cleaning tank 3 can be raised, and the operation time of the cleaning apparatus 1 can be shortened. For example, in the example of FIG. 3, when a series of operations from the first cleaning step S2 to the second rinsing step S5 is repeated, the cleaning water for the next first cleaning step S2 is used as the preheating tank in the second rinsing step S5. 4, the initial liquid temperature in the first washing step S2 can be increased as indicated by a two-dot chain line. As a result, the heating time in the heating step b can be shortened, and consequently the operation time can be reduced. Shortening can be achieved.

図4は、本発明の洗浄装置1の実施例2を示す概略構成図であり、一部を断面にすると共に一部を省略して示している。本実施例2の洗浄装置1も、その構成および運転方法において、基本的には前記実施例1の洗浄装置1と同様である。そのため、以下では、両者の異なる点を中心に説明し、対応する箇所には同一の符号を付して説明する。   FIG. 4 is a schematic configuration diagram showing a second embodiment of the cleaning apparatus 1 of the present invention, which is partially cut away and partially omitted. The cleaning device 1 of the second embodiment is basically the same as the cleaning device 1 of the first embodiment in its configuration and operation method. Therefore, below, it demonstrates centering around a different point of both, and attaches | subjects and demonstrates the same code | symbol to a corresponding location.

本実施例2の洗浄装置1は、前記実施例1の洗浄装置1と、洗浄槽加温手段7および予熱タンク加温手段14の構成において相違する。これら加温手段7,14として、前記実施例1では電気ヒータ40,62を用いたが、本実施例2では蒸気ヒータ71,72が用いられる。   The cleaning device 1 of the second embodiment is different from the cleaning device 1 of the first embodiment in the configuration of the cleaning tank warming means 7 and the preheating tank warming means 14. As the heating means 7 and 14, the electric heaters 40 and 62 are used in the first embodiment, but the steam heaters 71 and 72 are used in the second embodiment.

つまり、本実施例の洗浄装置1は、洗浄槽3内の底部には洗浄槽蒸気ヒータ71が設置され、予熱タンク4内の底部には予熱タンク蒸気ヒータ72が設置される。この場合、洗浄槽蒸気ヒータ71には蒸気が供給され、その凝縮水は蒸気トラップ73を介して排出される。この高温凝縮水は、たとえばオリフィスなどから構成される再蒸発機構74を通され、これにより減圧されることで再び蒸気化されて予熱タンク蒸気ヒータ72へ供給される。予熱タンク蒸気ヒータ72の出口には、蒸気トラップ(図示省略)を設けてもよい。   That is, in the cleaning apparatus 1 of this embodiment, the cleaning tank steam heater 71 is installed at the bottom of the cleaning tank 3, and the preheating tank steam heater 72 is installed at the bottom of the preheating tank 4. In this case, steam is supplied to the cleaning tank steam heater 71, and the condensed water is discharged via the steam trap 73. This high-temperature condensed water is passed through a re-evaporating mechanism 74 composed of, for example, an orifice, etc., and is reduced in pressure thereby to be vaporized again and supplied to the preheating tank steam heater 72. A steam trap (not shown) may be provided at the outlet of the preheating tank steam heater 72.

このような構成の場合、洗浄槽加温手段7からの排熱を用いて、予熱タンク4内の液体を加温することで、省エネルギーを図ることができる。また、洗浄槽蒸気ヒータ71からの凝縮水をそのまま予熱タンク4内の貯留水と熱交換する場合に比べて、凝縮水を一旦蒸気化してその凝縮熱伝達で予熱タンク4内の貯留水を加温するので、熱効率がよい。   In the case of such a configuration, energy can be saved by heating the liquid in the preheating tank 4 using the exhaust heat from the washing tank heating means 7. Further, compared with the case where the condensed water from the washing tank steam heater 71 is directly exchanged with the stored water in the preheating tank 4, the condensed water is once vaporized and the stored water in the preheating tank 4 is added by the condensation heat transfer. Because it warms, heat efficiency is good.

なお、図4では、洗浄槽加温手段7および予熱タンク加温手段14としてそれぞれ蒸気ヒータ71,72を用いたが、一方または双方を蒸気ジャケットとしてよい。つまり、洗浄槽3を取り囲むように蒸気が供給される蒸気ジャケットを設けたり、予熱タンク4を取り囲むように蒸気が供給される蒸気ジャケットを設けたりしてもよい。   In FIG. 4, steam heaters 71 and 72 are used as the washing tank warming means 7 and the preheating tank warming means 14, respectively, but one or both may be steam jackets. That is, a steam jacket to which steam is supplied so as to surround the cleaning tank 3 may be provided, or a steam jacket to which steam is supplied may be provided so as to surround the preheating tank 4.

本発明の洗浄装置1は、前記実施例の構成に限らず適宜変更可能である。特に、洗浄槽3とは別に予熱タンク4を設けて、予熱タンク4において次回の入れ替え用の液体を加温する構成において、洗浄槽加温手段7の停止中に予熱タンク加温手段14を作動させるか、洗浄槽加温手段7の排熱を用いて予熱タンク4内の液体を加温するのであれば、その他の構成や運転方法は適宜に変更可能である。   The cleaning device 1 of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. In particular, a preheating tank 4 is provided separately from the washing tank 3 to heat the next replacement liquid in the preheating tank 4, and the preheating tank heating means 14 is operated while the washing tank heating means 7 is stopped. If the liquid in the preheating tank 4 is heated using the exhaust heat of the washing tank heating means 7, other configurations and operation methods can be changed as appropriate.
