[The problem that the idea attempts to solve]

By the way, in the cleaning device having such a configuration, the cleaning water supplied from the injection pipe 3 is transferred to the cleaning water reservoir 2.
After the cleaning water has accumulated in the water, it is ejected from each fountain nozzle 4 to clean the inner surface of the test container 5, but there is a problem that the force of the jet of cleaning water is weak and a sufficient cleaning effect cannot be obtained in a short period of time. Ta. This seems to be because the flow rate of the injected cleaning water drops to almost zero in the cleaning water reservoir 2, so the pressure loss when increasing the flow rate again at the fountain nozzle 4 is extremely large.

In view of these conventional problems, the object of the present invention is to provide a cleaning device that sprays cleaning water vigorously and can effectively clean test containers in a short period of time.

[Means to solve the problem]

In order to achieve the above object, the present invention, as shown in the drawings of the embodiment, extends a plurality of branch pipes 23 from a distribution pipe 22 connected to a washing water injection pipe 21,

As shown in FIG. 10, the basket 40 consists of a receiving basket 41 and a lid basket 42.
As shown in FIG. 11, a bottom net 44 for receiving the bottom surface of the object to be cleaned 50 is stretched on the bottom surface of a frame 43 surrounding the four peripheries, and the object to be cleaned 50 is placed on the upper surface and in the middle of this frame 43. A grid-like partitioning net 45 is provided to arrange the items in an aligned manner and to divide and store the items so that they do not shift inadvertently. Further, as shown in FIG. 12, the lid basket 42 has a wire rod so as to have a square 48 on the upper surface of the frame 46 surrounding the four peripheries, which is exactly opposite to the upper end opening of each object to be cleaned 50 accommodated in the basket 41. A grid-shaped receiving net 47 is stretched, and the frame 46 is
Handles 4 that can be bent in the middle on both sides of the lower end of the
9 is rotatably attached. Further, the car positioning protrusion 30 is arranged so as to exactly engage inside the four corners of the frame 46.

When storing the objects 50 to be cleaned in the basket 40, first, the objects 50 to be cleaned are inserted into each section of the partitioning net 45 with the opening facing upward in the receiving basket 41 shown in FIG. , Next, cover the lid basket 42 shown in FIG. 12 over this basket 41, and
1 and the lid basket 42 are held down from above and below and turned over. Then, the basket 40 containing the object to be cleaned 50
can be carried by hanging it by the handle 49.

Reference numeral 17 designates locking protrusions protruding from both inner walls of the tank 11, with which the free end of the handle 49 is engaged with the bent middle part of the handle 49 in contact with the bottom of the basket 41. This prevents the car 40 from floating up.

In the above configuration, in order to clean the object 50 to be cleaned, as described above, the object 50 to be cleaned is placed in the receiving basket 41.
By inserting the lid basket 42 and inverting it with the cover basket 42 covered, the basket 40 accommodates the items to be cleaned 50.
The car 40 is suspended by the handle 49 and inserted into the tank 11, and the car 40 is placed on the injection device 20 while determining the position of the car 40 by the car positioning protrusion 30. The handle 49 is bent in the middle and the free end is engaged. It is locked by the stopper projection 17 to prevent it from lifting up.

In this state, the opening of the object to be cleaned 50 is located exactly opposite the water fountain 24. Next, the injection tube 21
When connected to a water faucet, etc., and pressurized tap water or cleaning water mixed with detergent, the cleaning water will flow to the distribution pipe 2.
2. The water passes through the branch pipe 23 and reaches the water fountain 24 without reducing the flow rate much, and is ejected from the water fountain 24 toward the inner surface of the object 50 to be cleaned, thereby cleaning the object 50 to be cleaned.

The cleaning water coming out of the opening of the object to be cleaned 50 accumulates in the tank 11, and when it reaches the overflow drain port 14, it is sequentially discharged to the outside from the overflow pipes 13a, 13b, and the water level is maintained at a substantially constant level.
This water level is set to such an extent that the car 40 is completely submerged. By doing this, the outer surface of the object 50 to be cleaned can be cleaned with the cleaning water, and the following effects can also be brought about in cleaning the inner surface.

That is, when the water level is low, the cleaning water spouted from the water fountain 24 flows smoothly along the inner surface and flows out from the side opening. On the other hand, if the water level is high, the water pressure will increase and the interior will be filled with cleaning water, and the jetted cleaning water will collide with the cleaning water inside, reducing the cleaning power, but the water level is maintained at an appropriate level. Then, the opening of the object to be cleaned 50 is closed with the cleaning water, and in this state, the cleaning water is violently jetted out from the water fountain 24, causing a turbulent flow in which the cleaning water entrains the air remaining inside. This creates a swirling flow that cleans the inner surface of the object 50 to be cleaned.

In this respect, even if the jetting force of the cleaning water from the water fountain 24 is weak, such an effect cannot be obtained, and this is also the reason why the cleaning power of the conventional device is weak. In this way, by force-feeding the cleaning water from the injection pipe 21 for several minutes, the object to be cleaned 50 can be almost completely cleaned. After washing, the supply of washing water is stopped, the basket 40 is taken out from the tank 11 and transferred to a drying table or drying device as appropriate, and the washing water in the tank 11 is drained by removing the drain plug 16.

In the illustrated example, the distribution pipe 22 and the branch pipe 23 are constructed of square pipes because it is easy to connect them and to make accurate holes for the water fountain 24, but it goes without saying that round pipes may also be used. Nor. Further, the height position of the overflow drain port 14 can be changed within a considerable range where the above-mentioned effect can be obtained.

[Effect of idea]

According to the cleaning device of the present invention, as is clear from the above description, a plurality of injection devices 20 for injecting cleaning water toward the object to be cleaned 50 are connected to a plurality of distribution pipes 22 connected to a cleaning water injection pipe 21. Since the main branch pipe 23 is extended and a plurality of water fountains 24 are bored at appropriate intervals on the upper surface of the branch pipe 23, the cleaning water pumped from the injection pipe 21 is transferred from the branch pipe 22 to the branch pipe. The water reaches the water spout 24 via the water jet 23 without extremely reducing the flow velocity, and is jetted out from the water spout 24 with great force to effectively clean the object 50 to be cleaned.

In addition, the tank 11 in which the injection device 20 is disposed at the bottom has an overflow drain port 14, and since the cleaning water accumulates up to the level of the overflow drain port 14, by appropriately setting the level, it is possible to The opening of the object 50 is closed with cleaning water, and the jetted water generates a turbulent swirling flow, allowing efficient cleaning and complete cleaning in a short time.

Furthermore, the object to be cleaned 50 is placed on the bottom surface of the frame 43 surrounding the four peripheries.
A bottom net 44 is stretched to receive the bottom surface of the frame 4.
3. A receiving basket 41 having a grid-like partitioning net 45 for partitioning and storing objects to be cleaned 50 on the upper surface and in the middle of 3.
and a lid basket formed by stretching a grid-like receiving net 47 having squares 48 capable of receiving the upper end openings of each object to be cleaned 50 housed in the receiving basket 41 on the upper surface of a frame 46 surrounding the four peripheries. 42 to form a basket 40 for storing the objects to be cleaned 50, and handles 49 which can be bent in the middle are rotatably attached to both sides of the lower end of the frame 46 of the lid basket 42.
A plurality of items to be cleaned 50 are inserted into each section of the partition net 45 with the opening facing upward, and then the lid basket 42 is placed from above the receiving basket 41.
By simply flipping the object 50 upside down, the object 50 to be cleaned is supported by the partition net 45 of the receiving basket 41 at two heights, upper and lower in the middle, and the upper end opening is in the square of the lid basket 42. 48 and held in a stable posture, which can reliably prevent the object 50 from being damaged due to carelessness during work, and because the basket 40 is separated from the tank 11, the device and the object 50 can be kept in a stable position.
The user can easily move between 0 storage locations by holding the handle 49.

Furthermore, the free end of the handle 49 can be engaged with and detached from locking protrusions 17 provided on both inner walls of the tank 11, and the four corners of the upper surface of the lid basket 42 can be attached to the injection device 20.
Since the car 40 containing the items to be cleaned 50 is engaged with the inside of the car positioning projections 30 which are provided upwardly projecting at the four corners of The opening of the object 50 to be cleaned and the water fountain 24 can be opposed to each other, and there is no risk of leakage or poor cleaning.

Moreover, the locking protrusion 17 is formed by bending the middle part of the handle 49 and bringing the bent middle part into contact with the bottom of the basket 41, and then protruding the free ends of the handle 49 from the inner walls on both sides of the tank 11. By engaging with the handle 49, the car 40 is pressed against the bent middle part of the handle 49 and is prevented from floating upward, and the car positioning protrusion 30 restricts displacement in the horizontal direction. Even if the object 50 to be cleaned stored in the basket 40 receives a strong pressure water flow spouting upward from the water fountain 24 of 23, the object 50 to be cleaned does not float up or move horizontally with the basket 40. There is no risk that the object 50 to be cleaned will be damaged.
