Abstract

PURPOSE:To automatically and efficiently wash test tubes by turning a test tube upside down to cover a water jet nozzle, disposing a shower nozzle opposite to the water jet nozzle, and spouting washing water from both nozzles for the time set in a timer. CONSTITUTION:The test tube 2 or a beaker turned upside down is supported with its inner side by the washing water supply pipe 6 attached with a flow rate control valve 5 and provided with water jet nozzle 1 at the top end. The washing water supply pipe 8 attached with a flow rate control valve 7 and provided with the shower nozzle 3 at the top end is disposed to the outside of the test tube 2 or the beaker supported with the nozzle 1. Single washing water supply main pipe 11 having a solenoid valve 10 in the midway is provided and both washing water supply pipes 6, 8 are branchedly connected to its top end. The solenoid valve 10 is opened for a set time by the operation unit 12 attached with the timer 13. As a result, the fluctuation of washing is eliminated, and unvisible chemicals and sample are perfectly washed off, and moreover, automatically and efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for automatically cleaning used test tubes and beakers.

(Prior Art) Conventionally, used test tubes and beakers were washed one by one by hand, and the degree of cleaning was visually inspected.

(Problem to be Solved by the Invention) However, when cleaning test tubes and beakers by hand as described above, there are variations in cleaning, and invisible chemicals and samples may not be completely washed away and may remain. there were. In addition, when washing by hand, it becomes dirty due to the accumulation of dirt and fat on the hands, and it is also time consuming and inefficient.

Therefore, the present invention aims to provide an automatic test tube/beaker cleaning device that can completely wash away invisible chemicals and samples without causing any variation in cleaning, and that can be cleaned automatically and efficiently. be.

(Means for Solving the Problems) In order to solve the above problems, the test tube/beaker automatic cleaning device of the present invention has a flow rate adjustment device equipped with a fountain-type nozzle tip that supports an inverted test tube/beaker from the inside. A cleaning water supply pipe with a valve, a cleaning water supply pipe with a flow rate adjustment valve equipped with a shower type nozzle at the tip located outside the test tube/beaker that supported the fountain type nozzle, and both purified water supply pipes. It consists of one wash water supply main pipe which is branched and connected at the tip and has a solenoid valve in the middle, and an operating device with a timer that opens the solenoid valve for a set time.

(Function) The automatic test tube/beaker cleaning device of the present invention configured as described above supports a used test tube/beaker upside down and placed over a fountain nozzle, and then activates an actuating device with a timer. Then, the solenoid valve is opened for the time set in advance on the timer, and the cleaning water is passed from the main cleaning water supply pipe to the two cleaning water supply pipes that are branched and connected to the tips of the main cleaning water supply pipes. Cleaning water is jetted from the nozzle to automatically clean test tubes and beakers from the inside and outside at the same time.

In this way, used test tubes and beakers are washed with the required amount of washing water for a certain period of time, and there is no unevenness in washing, and invisible chemicals and samples can be completely washed away and no residue remains. .

In addition, since it is automatically cleaned, it does not get dirty due to dirt from hands or fat, and it is efficient as it does not take much time.

(Example) An example of an automatic test tube/beaker cleaning device of the present invention, which is an automatic cleaning device for test tubes, will be explained with reference to FIG. The fountain nozzle 1 is as shown in Fig. 2a and b (a pipe with an inner diameter of 7 mm is constricted to 5 mm at the upper end, and a pipe with a diameter of 1.5 mm and a length of 6 m is placed at one place on the periphery of the upper end.
A protrusion ta of m is provided. 3 is a fountain nozzle
The shower type nozzle 3 has a diameter of 0.5 mm on the nozzle surface as shown in Fig. 3a and b.
17 mm diameter jet ports 4 are provided in a concentric arrangement. The fountain type nozzle 1 is directly installed at the tip of a cleaning water supply pipe 6 with a flow rate adjustment valve 5, and the shower type nozzle 3 is installed indirectly through a flexible tube 9 at the tip of a cleaning water supply pipe 8 with a flow rate adjustment valve 7. It is provided. Ryotora purified water supply pipe 6
．． 8 has a solenoid valve 10 in the middle as shown in FIG.
A branch connection is made to the tip of the main wash water supply pipe 11.

12 is a timer 13 for opening the solenoid valve lO for a set time;
The actuating device, in this example, is a foot switch (or a push button switch).

The automatic cleaning device of the embodiment configured as described above pushes up the shower type nozzle 3, turns the used test tube 2 upside down, covers it over the fountain type nozzle 1 as shown in FIG. After supporting the shower nozzle 3 with
In this example, pure water is passed from the main wash water supply pipe 11 to two wash water supply pipes 6.8 which are branched and connected to the ends of the main pipe 11, and the pure water is supplied from the fountain nozzle I and the shower nozzle 3 at each end. When the test tube 2 is spouted, the pressure of pure water jetted from the fountain nozzle 1 causes the test tube 2 to rotate around the protrusion 1a as a fulcrum, while simultaneously cleaning the inside and outside surfaces of the test tube 2 automatically.

Next, another embodiment of an automatic cleaning device for beakers will be explained with reference to FIG. Nozzle 1' has a spout 1 horizontally on the top surface.
A plurality of protrusion ICs, nine in this example, are provided. 3' is a shower type nozzle with a cylindrical hollow wall arranged concentrically on the outer circumferential side of the fountain type nozzle 1', and a diameter of 1 is provided on the inner circumferential surface.
A large number of jet ports 4' having a diameter of 1 mm are bored vertically and horizontally at regular intervals. The fountain type nozzle 1' is provided at the tip of a cleaning water supply pipe 6 with a direct flow rate adjustment valve 5, and the shower type nozzle 3
' is provided directly at the tip of the cleaning water supply pipe 8 with the flow rate regulating valve 7. The rest is the same as the embodiment shown in FIG. 1, so the explanation thereof will be omitted.

As shown in FIG. 4, the cleaning device of another embodiment constructed in this way is constructed by inverting a used beaker 2', placing it over a fountain type nozzle, supporting it with a protrusion IC, and pressing it with a foot. Press the switch 12 to open the solenoid valve IO for the time set in advance on the timer 13, and wash water, in this case pure water, is supplied from the wash water supply main pipe 11 to the tip of the main pipe 11.
When pure water is passed through the main cleaning water supply pipe 6.8 and jetted out from the fountain type nozzle bishower 2 nostle 3' at each tip, the beaker 2' is placed at the spout 1b next to the protrusion 1c of the fountain type nozzle 1'. The water pressure of the pure water jetted out rotates on the protrusion IC, and the inner and outer surfaces are automatically cleaned at the same time.

As shown in each of the above examples, the used test 2 beaker 2' is washed with the required amount of pure water for a certain period of time,
There is no variation in cleaning, and invisible chemicals and samples can be completely washed away without leaving any residue. In addition, since it is automatically cleaned, there is no chance of it getting dirty due to hand grime or fat adhering (and it is less time consuming and more efficient).

(Effects of the Invention) As can be seen from the above explanation, the automatic test tube/beaker cleaning device of the present invention prevents uneven cleaning of used test tubes/beakers and removes invisible chemicals and samples. It has the effect of being able to be completely washed off and also automatically and efficiently.
