の破泡作用。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to cleaning machines that use foam, such as dishwashers and washing machines, which blow air into the cleaning liquid to generate foam. The washed foam is successively supplied to the cleaning tank, and the object to be cleaned placed in the cleaning tank is immersed in the foam, and the object to be cleaned and the foam are brought into contact. foam-breaking effect.

されるものであった。したがって、洗浄には被洗浄物と
泡との接触が必ず必要となる。The dirt components on the object to be cleaned were removed by the mechanical force generated by the abrasion of the bubbles. Therefore, cleaning always requires contact between the object to be cleaned and the foam.

泡に浸漬されず、なかなか洗浄されないことになる。However, the foam that removed dirt (foam that dissolved dirt)
Since it contains a component with a low surface tension other than the surfactant, it will have a significant foam-breaking effect in the area that comes into contact with the object to be cleaned. This foam-breaking effect enhances the cleaning effect.Although this is desirable, since the foam does not rise above the broken surface, it can be seen on surfaces to be cleaned and in dishwashers. Objects to be cleaned in the upper part of the container are not immersed in the foam and are difficult to clean.
もう少し詳細に述べると、泡洗浄では汚れを有する最下

面となる。この接触面がある程度洗浄された段階で次の
接触面へと破泡面が移行する。To explain in more detail, in foam cleaning, cleaning starts from the lowest contact surface of the object to be cleaned, which has dirt, and this surface becomes the foam-broken surface. Once this contact surface has been cleaned to some extent, the bubble-broken surface moves to the next contact surface.

増し、騒音も高くなるという問題点があった。This is repeated one after another until the top is cleaned. Therefore, it generally takes a long time to clean the objects located at the top, depending on the amount of dirt. This phenomenon was particularly noticeable in dishwashers used to wash dirty dishes, etc., which contain a large amount of dirt components and oils and fats/proteins that have a significant foam-breaking effect. In order to shorten this time, it is effective to increase the amount of air blown, but when the amount of air blown is increased, the amount of detergent used increases and the noise level also increases.

The detergent is used in such a manner that the amount of foam supplied after the cleaning tank is substantially filled with foam is smaller than the amount of foam supplied from the start of foam supply until the cleaning tank is substantially filled with foam. The amount is reduced and the cleaning time is shortened.

した。FIG. 3 shows the relationship between the amount of air blown, the foam filling time, and the washing time until the dishes can be washed. The curve C shows the relationship between the amount of air blown and the foam filling time, the first curve shows the relationship between the amount of air blown and the cleaning time, and the curve E shows the cleaning time after the foam is filled, that is, D-C. Note that the washing conditions are as follows. Cleaning: 0.6% enzyme-containing anionic surfactant. Washing temperature 200℃
. Tableware for 20 people. Dirt: egg yolk, tallow, starch. Equipment used: Commercially available dishwasher (N'P 54 manufactured by Kishita Denki Co., Ltd.)
00) 1yo modified for foam cleaning. The foam filling time was defined as the time when the cleaning tank 9 was filled with foam and the foam entered the discharge path 9, and the cleaning time was defined as the time from turning on the switch until the end of rinsing.
第3図から明らかなように送風量すなわち泡の供給量と
洗浄時間D、および泡の充満時間Cには相関があり、送
風量が大きくなると、すなわち泡の供給量が多くなると
いずれの時間も短かくなる。As is clear from Fig. 3, there is a correlation between the air flow rate, that is, the foam supply amount, the cleaning time D, and the foam filling time C, and as the air flow rate increases, that is, the foam supply amount increases, both times It becomes shorter.
ところが泡が充満した後から洗浄が終るまでの時間Eは
、送風量にすなわち泡の供給量によっても大きく変って
いないことがわかる。これは泡が充満する過程で洗剤の
洗浄力、泡の擦過による機械力によって汚れの大部分が
落ちてしまい、泡が充満した後は残された少量の汚れを
除去するのみで従って破泡作用もあまりなく、大部分の
泡はすでに洗浄された被洗浄物を通過するのみで排出さ
れているためと考えられる。However, it can be seen that the time E from when the foam is filled until the end of cleaning does not change significantly depending on the amount of air blown, that is, the amount of foam supplied. This is because most of the dirt is removed by the cleaning power of the detergent and the mechanical force caused by rubbing the foam during the process of foam filling, and after the foam is filled, only a small amount of dirt that remains is removed, resulting in a foam-breaking effect. It is thought that this is because most of the bubbles are discharged only by passing through the object that has already been washed.
そこで、洗浄開始後泡が充満する寸では送風量を多くし
て泡の供給量を増し、泡が洗浄槽9内に充満した後は送
風量を低下させて泡の供給量を少なくして実験を行った
。その結果、洗浄時間は送風量を低下させずにすなわち
洗浄開始から終了また。例えば、洗浄開始後継続して送
風量を2001/minした場合、泡の充満に要する時
間は1o分、洗浄時間は22分であった。これを洗浄開
始後10分間は200 l /muで送ノ虱して泡を充
満させ、次いで60737酊に送風量を低下させた場合
、この時の洗浄時間も22分であった。Therefore, when the cleaning tank 9 is filled with bubbles after cleaning starts, the air flow rate is increased to increase the foam supply amount, and after the cleaning tank 9 is filled with bubbles, the air blow rate is decreased to reduce the foam supply amount. I did it. As a result, the cleaning time can be changed from the start to the end without reducing the air flow rate. For example, when the air flow rate was continued at 2001/min after the start of cleaning, the time required to fill with bubbles was 10 minutes, and the cleaning time was 22 minutes. When this was blown at 200 l/mu for 10 minutes after the start of cleaning to fill it with bubbles, and then the amount of air blown was lowered to 60737, the cleaning time at this time was also 22 minutes.
このように、泡を洗浄槽1内に充満させた後に、送風量
を低下させても洗浄時間が変わらないことから、泡が洗
浄槽1に充満するまでは大きな送風量で多量の泡を供給
し、充満後は送風量を小さくし泡の供給量を少なくして
洗浄することが可能となる0ところで多量の泡を供給し
ている段階では被洗浄物8の汚れ面で破泡しているので
泡は一挙に洗浄槽1内に充満することはなく、漸次充満
し、その過程では排出径路9からの泡の排出はない。In this way, even if the air flow rate is reduced after the cleaning tank 1 is filled with foam, the cleaning time does not change, so a large amount of foam is supplied with a large air flow rate until the cleaning tank 1 is filled with foam. However, after filling, it is possible to clean by reducing the amount of air blown and the amount of foam supplied.At 0, when a large amount of foam is being supplied, the foam is broken on the dirty surface of the object 8 to be cleaned. Therefore, the cleaning tank 1 is not filled with foam all at once, but is gradually filled with foam, and no foam is discharged from the discharge path 9 during this process.
そして泡が洗浄槽1内に充満すると泡は排出径路9を通
り泡検知器10で泡の通過が検知され更に消泡器13で
消泡されて排出される。なお、泡検知器10で泡の通過
を検知すれば送風量を小さくするよう泡発生装置が制御
される。もし泡が洗浄槽1内に充満後も送風量が大きい
itたと洗浄槽1内ではほとんど破泡されていないから
発泡した泡すべてが洗浄槽外に排出されることになり、
洗剤の使用量は多大なものとなる。しかし、洗浄槽1内
に泡が充満した後は泡の供給を少なくすることができる
ので、送風量を低下させれば排出される泡の量も少なく
なり、当然のごとく洗剤の使用量も低減することができ
る。また送風量を低下させた場合は騒音も小さいものと
なる。When the cleaning tank 1 is filled with bubbles, the bubbles pass through the discharge path 9, the passage of the bubbles is detected by the bubble detector 10, and the bubbles are further defoamed by the defoamer 13 and discharged. Note that if the bubble detector 10 detects passage of bubbles, the bubble generator is controlled to reduce the amount of air blown. If the air flow rate is large even after the cleaning tank 1 is filled with foam, the bubbles will hardly be broken in the cleaning tank 1, and all the foamed foam will be discharged outside the cleaning tank.
The amount of detergent used becomes large. However, once the cleaning tank 1 is filled with foam, the supply of foam can be reduced, so if the air flow rate is reduced, the amount of foam discharged will also be reduced, which will naturally reduce the amount of detergent used. can do. Further, when the air flow rate is reduced, the noise is also reduced.
なお最初から50117m1nで洗浄すると、洗浄槽1
に泡が充満するのに55分間かかり、洗浄時間も80分
以上を要するので、洗浄開始時から泡が充満する捷で送
風量を大きくすることは、洗浄時間の短縮につながると
いえる。Note that if you wash with 50117ml from the beginning, cleaning tank 1
It takes 55 minutes to fill with bubbles, and the cleaning time also takes 80 minutes or more, so increasing the amount of air blown from the beginning of cleaning when the chamber is filled with bubbles can shorten the cleaning time.

It is advantageous in terms of resource saving and pollution, and has great industrial value. It is particularly useful for dishwashers, which contain many dirt components and foam-breaking components.
