Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cleaning device for cleaning mechanical parts, medical instruments, and other various purposes, and which performs steam cleaning and cooling drying in one cleaning space. The aim is to make it smaller so that it can be used.

BACKGROUND TECHNOLOGY Conventionally, there are two methods for performing steam cleaning and cooling drying in one cleaning device. One of them is to use a steam cleaning tank and a cooling drying tank. Although located laterally, this device has the disadvantage that it occupies a very large floor area. In addition, in order to eliminate this drawback, a system was developed in which the steam cleaning section and the cooling drying section were located in two separate spaces vertically.
It is known as No. 57-39684. This method of locating the steam cleaning section and the cooling drying section in the vertical direction is as follows.
Although this is excellent in terms of reducing the area occupied by the device, the height in the vertical direction is large, which is not preferable in terms of installation location and operability.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems, and by performing the steam cleaning section and the cooling drying section in one cleaning space, the occupied area of the device can be reduced. This is intended to make it possible to reduce the height in the vertical direction.

Means for Solving the Problems The present invention solves the above problems by:
The cleaning section, which performs steam cleaning and cooling drying of the objects to be cleaned, is formed by dividing it with a flat partition wall fixed inside the cleaning tank main body, and the cleaning section and the adjacent cleaning tank main body are separated through this partition wall. A cooling section for condensing cleaning steam is provided between the inner circumferential surfaces, and a communication gap is provided between the lower end of the partition wall and a concave groove provided on the inner circumference of the cleaning tank to allow steam to communicate between the cooling section and the cleaning section. The communication gap is formed so that it can be closed by injecting cleaning liquid into the recessed groove and opened by discharging the cleaning liquid.

Function Since the present invention is configured as described above, in order to perform liquid cleaning, the cleaning tank main body is filled with cleaning liquid, and the object to be cleaned is inserted and immersed in this cleaning liquid. Can be washed. Next, to perform steam cleaning, the cleaning liquid is removed from the cleaning tank main body, so that the cleaning liquid remains only in the groove, and the cleaning part and the cooling part are separated into flat plate-like sections with the communication interval closed. Separate with walls. Then, if cleaning steam is generated and introduced into the cleaning section, this cleaning steam will fill the cleaning section inside the partition wall,
Steam cleaning can be performed by contacting the object to be cleaned. After this steam cleaning is completed, the cleaning liquid in the groove is removed and the communication section is opened, so that a communication section is formed at the lower end of the partition wall, and the cleaning steam, which has a higher specific gravity than the air inside the partition wall, is Since it is guided to the cooling part via the communication part and condensed and liquefied, the cleaning vapor inside the partition wall disappears and the cold air from the cooling part
The cleaning section inside the partition wall is cooled, and the object to be cleaned can be cooled and dried.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a cleaning tank body, which can be filled with an appropriate cleaning liquid 2 such as trichlorethylene, and a cleaning table on which an object to be cleaned 3 is placed. 4 is located on the upper surface of the lower bottom wall 5. This washing stand 4 may be fixedly located on the upper surface of the lower bottom wall 5, but it can move up and down within the washing tank main body 1 in conjunction with a lifting cylinder etc. formed outside the washing tank main body 1. Good as a thing. Also,
A steam generation tank 7 equipped with a heater 6 is located next to the cleaning tank body 1, and the upper space 8 of the steam generation tank 7 and the cleaning tank body 1 are connected via a steam outlet pipe 10. , steam can be introduced into the cleaning tank body 1. In addition, inside the cleaning tank body 1, a cleaning liquid 2 for closing is provided at a position slightly higher than the lower bottom wall 5.
A concave groove 11 that can be filled is formed linearly.
A supply/discharge pipe connected to a pump for filling or discharging the cleaning liquid 2 may be connected to this groove 11, but a discharge plug or the like may be provided to prevent the cleaning liquid 2 from flowing inside the groove 11.
It may also be used as something to discharge.

Further, a flat plate-shaped partition wall 13 located across the lower bottom surface of the groove 11 and the steam communication interval 12 is fixed to the inner surface of the cleaning tank main body 1 to partition the inside of the cleaning tank main body 1. One side of this partition wall 13, that is, the side on which the cleaning table 4 of the cleaning tank main body 1 is placed, is used as a cleaning section 14 that serves as both a steam cleaning section and a cooling drying section, and the other side of the partition wall 13, that is, the side on which the washing table 4 of the cleaning tank main body 1 is placed, serves as a cleaning section 14 that serves as a steam cleaning section and a cooling drying section. A cooling part 15 for steam condensation is provided between the cleaning part 14 and the inner surface of the cleaning tank main body 1 adjacent to the cleaning part 14 via the wall 13, in which a coiled pipe through which cooling water flows is formed in a box shape. The cooling section 15 and the cleaning section 14 are connected through the communication interval 12, and when the closing cleaning liquid 2 is supplied to the groove 11, the communication interval 12 at the lower end of the partition wall 13 is closed by the cleaning liquid 2. It becomes something that is closed. Further, the upper surface of the cleaning tank main body 1 is covered with a lid 16.

In the apparatus constructed as described above, as shown in FIG. 1, if the cleaning tank main body 1 is filled with the cleaning liquid 2 and the object to be cleaned 3 is placed on the cleaning table 4, the cleaning liquid 2 can be used for cleaning. It can be performed.

After this liquid cleaning, as shown in FIG. 2, the cleaning liquid 2 in the cleaning tank body 1 is extracted by a pump or the like, and the steam outlet pipe 10 is exposed in the cleaning section 14. In this state, the lower end of the partition wall 13 is inserted into the closing cleaning liquid 2 in the groove 11, and communication between the cooling part 15 for steam condensation and the inner surface of the partition wall 13 via the communication interval 12 is cut off. Therefore, cleaning steam fills the cleaning section 14 through the outlet pipe 10 from the steam generating tank 7 installed adjacent to the cleaning tank main body 1, and cleans the object 3 on the cleaning table 4. Steam cleaning can be performed on contact. After this steam cleaning is completed, as shown in the third diagram, by extracting the closing cleaning liquid 2 from inside the groove 11, a communication gap 12 is created between the lower end of the partition wall 13 and the bottom surface of the groove 11. is formed, and the cleaning steam, which has a specific gravity heavier than air, is guided to the cooling part 15 via the communication interval 12, and the steam in the direction of the lower bottom wall 5 of the cleaning tank body 1 is also directed to the cooling part 15.
Since the cleaning vapor in the cleaning section 14 disappears, the cleaning section 14 is cooled by the cold air from the cooling section 15, and the object 3 to be cleaned can be cooled and dried. After this cooling and drying is completed, the lid 16 is opened and the object 3 to be cleaned on the washing table is taken out. Further, the next object to be cleaned 3 is placed on the cleaning table 4, and the cleaning operation is repeated by the same operation as described above.

Effects of the Invention Since the present invention is configured as described above, the steam cleaning section and the cooling drying section were formed in the same space, instead of the conventional structure in which the steam cleaning section and the cooling drying section were formed in separate spaces. The cleaning device can be used for multiple purposes in the same space, the height of the cleaning device can be made significantly lower than before, the installation location can be arbitrarily determined, and the operability is also good.
