Description

[Detailed explanation of the invention] "Industrial application field" Various samples of this invention are separated using centrifugal force.
The present invention relates to a centrifugal separator used for precipitation, etc., and in particular to its casing.

``Prior Art'' As shown in FIG. 3, a conventional centrifuge casing has an opening 12 formed on the top surface of the casing body, and a rotor chamber 13 is formed inside the casing body 11 inside the opening 12. Although not shown in the figure, a rotor is rotatably arranged in the rotor chamber 13, and the rotor is rotated by a motor (not shown in the figure) inside the case body 11, so that a sample attached to the rotor is centrifuged. is being done.

The operation panel 14 is located on the top surface of the case body 11, opening 1
It is located behind 2. The operation panel 14 includes a rotor rotation speed setting section, a rotation time setting section,
A power switch, a speedometer, a temperature setting section in the rotor chamber, and various indicators are provided. A lid 15 that covers the opening 12 is attached to one side of the upper surface of the case body 11 and opens laterally.

In this conventional centrifuge housing, when the lid 15 is opened, the space occupied by the centrifuge increases in the lateral direction. For this reason, when a number of centrifugal separators are used in close proximity, if one centrifuge has its lid open, it is difficult to use the centrifugal separator next to it. Also, even if there is only one unit, the lid stands diagonally across the opening, so it may get in the way of removing or attaching the bucket (for attaching the sample container to the rotor) from the rotor. However, when taking out a centrifuged sample, it sometimes bumped against the lid, causing the sample to spill or remixing the separated sample. In this respect, it is preferable for the lid to open front and back rather than one that opens sideways.

Conventionally, in a centrifugal separator with a lid that opens and closes back and forth, the axis of rotation of the lid 15 is located after the opening 12 and in front of the operation panel 14, as shown in FIG. Therefore, when the lid 15 is open, the front surface of the operation panel 14 is hidden by the lid 15.
After using the centrifuge, I could not see the settings on the operation panel 14 and sometimes forgot to turn off the power.
In addition, since the lid 15 is attached to the case body 11 between the opening 12 and the operation panel 14, the operation panel 14 is located considerably rearward, making it difficult to operate the operation panel 14 in some cases.

There is also one in which the lid 15 can be opened from front to back and the operation panel 14 is located in front of the opening 12.
In this case, it is easy to operate the operation panel 14, but when loading and unloading the sample into the rotor chamber, the sample may be accidentally spilled on the operation panel, causing an electrical failure, or the opening 12 may be moved backwards by the distance of the operation panel 14. Because of its location, it is difficult to attach or remove the rotor from the motor shaft in the rotor chamber, and similarly, it is difficult to attach or remove the sample bucket from the rotor.

``Means for solving the problem'' According to this invention, a notch is formed in the lid on the side where the operation panel is attached to avoid the operation panel, and the opening/closing axis of the lid is from the front (front) of the operation panel. It is also located at the back, extending from side to side.

In other words, the lid opens forward, and its pivot axis is located at least at the rear of the front of the operation panel. However, since there is a notch at the bottom of the lid, the lid can be opened and closed without the operation panel getting in the way. Furthermore, when the lid is open, the front surface of the operation panel appears in front of the notch, so that it is not hidden and it is difficult to forget to turn off the power. Additionally, the operation panel is located further forward than conventional front-opening models, making it easier to operate.

"Example" Figures 1 and 2 show an example of this invention.
Parts corresponding to those in FIG. 3 are given the same reference numerals. In FIG. 1, there is a rotor 2 in the rotor chamber 13.
1 is mounted on a motor shaft 22, and a bucket 23 is suspended from the rotor 21. Further, in this example, the opening 12 is not circular, but the rear peripheral edge is linear extending left and right, and the operation panel 14 is positioned that far forward.

In this invention, the lid 15 is front-opening, and a rectangular notch 31 is provided on the side where the lid 15 is attached to the case body 11.
is formed. The opening/closing axis 32 of the lid 15 is located behind the front surface 14a of the operation panel 14 and extends left and right. In the illustrated example, a hinge 33 is attached to the upper rear surface of the case body 11, the axis of the hinge 33 is close to the rear edge of the upper surface of the case body 11, and the lid 15 is attached to this hinge 33. Further, the depth d of the notch 31 is set to a value such that the operation panel 14 does not get in the way when the lid 15 is opened and closed. Furthermore, when the lid 15 is opened, at least the front 1 of the operation panel 14
4a is positioned approximately in front of the notch 31.

"Effects of the Invention" As described above, according to this invention, since the front surface 14a of the operation panel 14 can be seen from the front with the lid 15 open, there is less risk of forgetting to turn off the power. The opening/closing axis 32 of the lid 15 is the operation panel 14
Since the operation panel 14 is located further back than the front face 14a of the
The operation panel 14 is easy to operate.

Moreover, since the operation panel 14 is located at the rear rather than the front, it is easy to attach and remove the rotor 21 and the bucket 23, there is no risk of spilling the sample on the operation panel 14, and there is little chance of electrical failure. Become something. Also lid 15
Since the centrifugal separators are front-opening, even if multiple centrifugal separators are used side by side, there is no risk of difficulty in handling adjacent centrifuges, and the space occupied in the lateral direction can be reduced.
