Abstract

PURPOSE:To effectively supply a washing liquid to an object to be washed and besides to effectively utilize it by forming a bottom shape of a washing tank to the shape which conforms with a bottom shape of a carrier for an object to be washed. CONSTITUTION:The washing liquid flows into the inside through straightening plates 18 formed on the bottom of the carrier 13 for an object to be washed by feeding the washing liquid into the washing tank 14 from a washing liquid supply pipe 17 via a liquid delivery port 11, and fills the washing tank 14 and then overflows from an overflow machine tank 15 in the upper edge. When the washing liquid flows from underside to upper side in the carrier 13 for object to be washed, the object 12 to be washed which is housed in the carrier 13 for object to be washed, is washed. The bottom of the washing tank 14 is formed to the shape which conforms with the bottom shape of the carrier 13 for object to be washed and also has a holding mechanism of the carrier 13 for object to be washed and beside the washing liquid can be effectively utilized without leaking from the bottom to the circumference. Thus, the washing liquid is not wasted unwittingly and the washing effect is enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores an object to be cleaned in a cleaning tank, supplies the cleaning liquid continuously or intermittently from the bottom of the cleaning tank, and supplies the cleaning liquid from an upper portion of the cleaning tank. The present invention relates to an overflow type cleaning apparatus for cleaning an object to be cleaned stored in a carrier to be cleaned.

[0002]

2. Description of the Related Art Conventionally, this type of overflow type cleaning apparatus supplies a cleaning liquid substantially uniformly from a large number of holes provided on the bottom surface of the cleaning tank and operates an overflow mechanism at the upper end of the cleaning tank. The cleaning liquid is allowed to overflow, and the cleaning target accommodated in the cleaning target carrier accommodated in the cleaning tank is cleaned.

[0003]

However, in the above-mentioned conventional overflow type cleaning apparatus, the size of the bottom surface of the cleaning tank is relatively large as compared with the carrier to be cleaned, and the carrier to be cleaned is further increased. In many cases, since the fluid resistance increases, the flow rate of the cleaning liquid to the vicinity of the object to be cleaned, which requires more cleaning, becomes relatively very small. Therefore, in order to secure a required fixed amount of cleaning liquid flow near the object to be cleaned, a large amount of cleaning liquid is required as a whole. As described above, the conventional overflow-type cleaning tank has a problem in that the flow rate of the cleaning liquid contributing to cleaning the object to be cleaned is smaller than the total flow rate of the cleaning liquid.

The present invention has been made in view of the above-mentioned problems, and it is an overflow type cleaning which eliminates the above-mentioned problems, can effectively supply a cleaning liquid to an object to be cleaned, and can efficiently use the cleaning liquid. The purpose is to provide a device.

[0005]

In order to solve the above-mentioned problems, the present invention is provided with a cleaning tank 14, a cleaning solution is supplied from the bottom of the cleaning tank, and the cleaning solution is supplied from the upper end of the cleaning tank 14 with an overflow. In an over-flow type cleaning apparatus for causing a flow and cleaning the cleaning object 12 stored in the cleaning object carrier 13 stored in the cleaning tank 14, the shape of the bottom surface of the cleaning tank 14 is cleaned. It is characterized in that it is formed according to the shape of the bottom surface of the object carrier 13.

Further, the cleaning tank 14 has a carrier 13 to be cleaned.
A carrier positioning guide 16 for positioning and holding the cleaning target carrier 13 is held at a predetermined position.

[0007]

In the present invention, since the shape of the bottom surface of the cleaning tank 14 is formed so as to match the shape of the bottom surface of the object carrier 13 to be cleaned,
The cleaning liquid that has flowed in from the bottom surface flows into the carrier through the bottom surface opening of the cleaning target carrier 13, and the amount that flows out through the bottom surface opening decreases. That is, even if the fluid resistance in the object carrier 13 is relatively large, most of the cleaning liquid flows to the portion requiring cleaning. Therefore, the cleaning liquid is effectively used without being wasted.

By providing the carrier positioning guide 16, it is possible to position and store the object carrier 13 to be cleaned at a predetermined position in the cleaning tank 14 by a simple operation.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing a schematic configuration of an overflow type cleaning apparatus of the present invention, FIG. 1 is a front sectional view, and FIG. 2 is a side sectional view. FIG. 3 is a diagram showing the structure of the carrier to be cleaned,
1A is an external view, FIG. 1B is a front sectional view, FIG. 1C is a side sectional view, and FIG. 1D is a plan view. In the figure, 14 is a cleaning tank, and the front cross section of the bottom of the cleaning tank 14 is a so-called fan shape with a wide top and a narrow bottom, and the side cross section is a rectangular shape with the same top and bottom. A perforated straightening plate 18 is provided at the bottom opening of the cleaning tank 14. Reference numeral 11 denotes a fluid outlet provided in connection with the bottom opening of the cleaning tank 14, and a cleaning liquid supply pipe 17 is connected to the outlet. The cleaning tank 14 contains a cleaning object carrier 13 in which the cleaning object 12 is stored.

Similar to the cleaning tank 14, the bottom of the carrier 13 to be cleaned has a so-called fan shape whose front cross section is wide and narrow at the bottom. It has a shape. Then, the bottom surface of the cleaning target carrier 13 and the bottom surface of the cleaning tank 14 are shaped to match each other. Although not shown in the drawings, the inner wall surface of the object to be cleaned 13 is provided with a number of slits, and the ends of the object to be cleaned 12 are inserted into the slits so that the objects to be cleaned 12 are substantially spaced. The object to be cleaned 13 is stored in the carrier 13. Further, when the cleaning liquid is supplied from the cleaning liquid supply pipe 17 into the cleaning tank 14, the cleaning liquid filling the cleaning tank 14 is overflowed from the overflow mechanism 15 at the upper end.

In the over-flow type cleaning device having the above-mentioned structure, the cleaning liquid is supplied from the cleaning liquid supply pipe 17 into the cleaning tank 14 through the fluid discharge port 11 so that the cleaning liquid is supplied to the carrier 13 to be cleaned. It flows through the straightening plate 18 provided on the bottom surface to fill the cleaning tank 14, and the upper end is opened.
Overflow from the overflow mechanism 15. When the cleaning liquid flows from the bottom to the top in the cleaning target carrier 13, the cleaning target 12 housed in the cleaning target carrier 13 is cleaned. The current plate 18 may be provided in the fluid discharge port 11 instead of the bottom surface of the cleaning tank 14.

The bottom of the cleaning tank 14 has a carrier 13 to be cleaned.
Formed according to the shape of the bottom surface of the cleaning target carrier 13
It also serves as a holding mechanism for the cleaning liquid and allows the cleaning liquid to be effectively used without leaking from the bottom to the surroundings and flowing.
Further, the carrier position guide 16 holds the carrier position in the cleaning tank 14 at a predetermined position.

[0013]

As described above in detail, according to the present invention, the shape of the bottom surface of the cleaning tank is formed so as to match the shape of the bottom surface of the object carrier, so that the cleaning liquid flowing from the bottom surface is the object to be cleaned. The amount that flows into the carrier from the bottom opening of the carrier and flows out from the bottom opening decreases, so that the cleaning liquid can be effectively used without being wasted, and at the same time, the cleaning liquid can be applied to all surfaces of the object to be cleaned. Is effectively supplied, and the excellent effect that the cleaning effect is improved is obtained.
