Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to electric parts and precision parts,
More particularly, the present invention relates to a method and apparatus for cleaning objects to be cleaned, such as automobile parts, and a device for cleaning the objects.

[0002]

2. Description of the Related Art Conventionally, in order to clean an object to be cleaned such as electric parts, precision parts, automobile parts, etc., a hanging basket containing the object to be cleaned is mounted and immersed in a cleaning liquid in a cleaning tank. Is widely practiced.

In order to efficiently wash the object to be washed, the hanging tool is swung to swing the washing basket.

Therefore, the cleaning liquid in the cleaning tank is contaminated by cleaning the object to be cleaned, so that fresh cleaning liquid is appropriately replenished or replaced.

[0005]

However, when the cleaning liquid in the immersion tank becomes extremely dirty, the cleaning liquid must flow out to clean the inside of the immersion tank, which is time-consuming and requires a worker to perform dirty work. I didn't like it.

It is also known to suspend an object to be cleaned in an evaporator for steam cleaning. However, since the cleaning solution is directly loaded in the evaporator, the cleaning solution is contaminated like the cleaning tank described above. It had to be discharged and the inside of the evaporator had to be cleaned, which was a problem for the cleaning work.

[0007]

The present invention has been made in view of the above points, and in order to solve the above-mentioned problems, a heat-resistant bag having a cleaning liquid such as alcohol loaded in an evaporator is provided. (EN) A vapor cleaning method and device, which are exchangeably mounted, in which an object to be cleaned is suspended inside the heat-resistant bag and the object to be cleaned is cleaned with the steam of a cleaning liquid such as alcohol. .

[0008]

According to the present invention, a heat-resistant bag containing a cleaning solution such as alcohol is exchangeably mounted in the evaporator, and an article to be cleaned is hung inside the heat-resistant bag so that the alcohol or the like can be suspended. By cleaning the object to be cleaned with the cleaning solution vapor, the object to be cleaned is steam-cleaned and the cleaning solution is concentrated or contaminated.

The dirty cleaning liquid can be subjected to a concentrated liquid treatment or the like as it is in a heat-resistant bag, and the cleaning liquid can be collected or discarded.

[0010]

EXAMPLES The present invention will be described below based on examples. FIG. 1 shows an embodiment of the present invention. The vapor cleaning device 1 can be operated by using a bottomed cylindrical evaporator 2 having a required heat insulating structure as shown in FIG.

On the inner wall 3 of the evaporator 2, the heat-resistant bag 4 is attached to the inner wall 3 in this manner, and the cleaning liquid 5 is placed on the heat-resistant bag 4.
Is loaded in a predetermined amount and the cleaning liquid 5 in the heat-resistant bag 4 is heated and evaporated by the heater 6 of the evaporator 2, and the steam can be used to clean the cleaning object 7 such as electric parts, precision parts, and automobile parts. I have to.

The heat-resistant bag 4 may be made of heat-resistant nylon such as nylon 6 or nylon 66, and if necessary, may be made of metal foil such as aluminum foil or stainless steel foil. It is particularly effective when the cleaning liquid is a solvent.

The heat-resistant bag 4 has an opening edge 8 portion shown in FIG.
As described above, a plurality of hook-shaped locking members 9 protruding from the upper portion of the inner wall 3 of the evaporator 2 are pierced or locked to be suspended along the inner wall 3 of the evaporator 2. .

The heat-resistant bag 4 is loaded with a predetermined amount of a cleaning liquid 5 such as a hydrocarbon-based solvent such as isopropyl alcohol or a mixed liquid of aromatic hydrocarbons and a plurality of polar solvents, and an object to be cleaned 7 is cleaned.
When the cleaning liquid becomes concentrated after steam cleaning, vaporizer 2
The heat-resistant bag 4 is removed from the locking tool 9 projecting from the inner wall 3 of the above, and the heat-resistant bag 4 is discarded as it is.

A condenser 11 is provided above the evaporator 2 as shown in FIG. 1 so as to surround the cooling coil 10 so as to pass water through the cooling coil 10. The steam scattered to the upper part is made to flow toward the condenser 11 side to remove latent heat and condense, and is collected in the gutter part 12 provided in the peripheral part and collected in the outer collecting can (not shown). In addition,
If necessary, it can be refluxed into the heat-resistant bag 4 via a conduit (not shown) or the like.

On the upper surface of the evaporator 2 thus constructed,
The lid 13 is attached so as to be openable and closable, and the object to be cleaned 7 suspended by the suspending tool 14 is suspended above the heat-resistant bag 4 in the evaporator 2 for steam cleaning.

Then, as shown in FIG. 1, a predetermined amount of cleaning liquid 5
The heat-resistant bag 4 loaded with is locked and attached to the inner wall 3 of the evaporator 2, and the heater 6 of the evaporator 2 heats and evaporates the cleaning liquid 5.

Then, the lid 13 is opened, and the object to be cleaned 7 hung on the hanging tool 14 is inserted into the evaporator 2 and is positioned above the heat-resistant bag 4 for a predetermined period of time for steam cleaning. It is something to take out.

When the cleaning liquid 5 becomes dirty and concentrated after cleaning in this manner, the heat-resistant bag 4 is taken out, the heat-resistant bag 4 loaded with a new cleaning liquid 5 is attached, and the cleaning of the object 7 to be cleaned is continued. can do. It should be noted that the cleaning liquid 5 can be replaced as appropriate even when it becomes dirty to a certain extent or more.

Therefore, it is not necessary to discharge the cleaning liquid in the evaporator to clean the inside of the evaporator, and the dirty cleaning liquid can be collected together with the heat-resistant bag, so that the dirty work is required. The work will be improved because there is no problem.

The vapor of the cleaning liquid evaporated in the evaporator is deprived of latent heat in the condenser and liquefied, and flows into the trough to be recovered.

In the above embodiment, the evaporator is small in size and the object to be cleaned is put in and out through the hanging tool. However, if the evaporator is large in size, the object to be cleaned is hung on a trolley conveyor or the like and continuously. It is also possible to carry out steam cleaning, and it is possible to make appropriate specifications in accordance with the processing amount.

The heat-resistant bag is preferably made of an inexpensive heat-resistant synthetic resin material, but as described above, a metal material can also be used, and the thermal conductivity from the heater is good and the thermal efficiency is improved. Is something to be stripped.

Further, the heat-resistant bag is pierced into a hook-shaped locking device so that it can be exchangeably mounted on the evaporator. The present invention can be appropriately carried out based on the spirit of the present invention, such as locking.

[0025]

As described above, according to the present invention, the object to be cleaned can be steam-cleaned, and the cleaning solution can be replaced together with the heat-resistant bag when the object to be cleaned is cleaned and the cleaning solution is concentrated or contaminated. In particular, the cleaning liquid in the evaporator can be subjected to a concentrated liquid treatment or the like in a heat-resistant bag, and the cleaning liquid can be collected or discarded through the condenser.

Therefore, even if the inside of the evaporator is not contaminated and the cleaning liquid is contaminated, it is not necessary to discharge the cleaning liquid in the evaporator, and cleaning is not required. It can be improved.
