DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifuge for rotating a rotating body at a high speed and a display method thereof.

[0002]

2. Description of the Related Art Conventionally, when using a centrifuge, a user needs to adjust the rotation speed, operation time (separation time),
The separation conditions such as the holding temperature were changed. For this reason, the centrifuge is provided with a display device for displaying centrifugation conditions and the like. The display section of this display device generally has 7
In many cases, segment LEDs are displayed side by side, and by pressing a predetermined switch, setting conditions input to the centrifuge can be displayed, or an actual operating state can be displayed. The above-described switching of the display content is configured to be performed by key operation.

[0003]

In a centrifuge in which the display contents are switched by pressing a predetermined switch (key), a user always looks at a display unit when putting a sample into the centrifuge or before operating the centrifuge. We are checking that there are no errors in the setting conditions such as the rotation speed, operation time, and holding temperature. That is,
The user presses a predetermined switch to display the setting conditions input to the control storage unit of the centrifuge on the display unit, and then presses the start button of the centrifuge to start the operation. Therefore, the user has to perform a switch operation for displaying on the display unit every separation, and there is a problem that the user feels troublesome in this operation.

An object of the present invention is to solve the above-mentioned problems and to provide a centrifuge having a display device excellent in workability and operability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A display device and a display method of a centrifuge according to this embodiment will be described with reference to FIGS. FIG. 1 is a flowchart illustrating a display method of a centrifuge according to the present embodiment, and FIG. 2 is a block diagram illustrating a centrifuge having a display device according to the present embodiment. 1 and 2, a user opens a door 21 for sealing a rotating chamber 22, and mounts a rotating body 23 containing a sample on a driving shaft rotated by a driving device 24. The open / closed state of the door 21 is detected by the door open / close detector 28 and taken into the control unit 29 to determine the open / closed state of the door 21 as shown in step 110. If the door 21 is open, step 111
Since the setting conditions of the centrifuge are displayed on the display unit 26 of the display device as shown in FIG. 7, the user can input and set the centrifugation conditions from the operation unit 27 while checking the display unit 26. Then, when the door 21 is closed and the start button of the centrifuge is pressed as shown in step 120, the control unit 29 supplies power to the driving device 24 to rotate the rotating body 23, and the display unit 26 displays the actual The operating status is displayed.

As another display method, when the rotor 21 is mounted on the drive shaft and the door 21 is closed and the centrifugal condition is input and set, the process proceeds to Steps 130 and 131, and the process is continued even if the door 21 is closed. The time is displayed on the display unit 2 in this state in order to display the setting conditions of the centrifuge as shown in step 132.
While confirming Step 6, the input setting of the centrifugation conditions can be performed. Thereafter, by pressing the start button of the centrifuge, the actual operation state is displayed on the display unit 26.

As described above, by setting the jump destination of the branch NO in step 120 to step 111, the setting conditions of the centrifuge are displayed on the display unit 26 until the door 21 is closed and the start button is pressed. However, preparative cooling (closing the centrifuge door 21 to cool the rotating chamber 22) is required for separation work performed at a relatively low temperature such as an enzyme. Therefore, it is necessary to display the rotation speed 0 min ^-1 (stop state) on the display unit 26. Therefore, when the door 21 is closed, it is preferable for the user to display the actual driving state as much as possible instead of the set condition, because the usability is improved. Therefore, as shown in step 121, the actual operation state of the centrifuge may be displayed after the door 21 is closed and a predetermined time has elapsed.

Although the above-described display contents are controlled by software, the display contents can be selected according to the centrifugation, that is, by controlling any of the above-mentioned steps to be selectable, the workability and the workability can be improved. Operability can be improved.

[0014]

According to the present invention, by providing a control unit for changing the display content of the display unit according to the open / closed state of the door, the centrifuge can be used without pressing a predetermined switch when using the centrifuge. Can automatically be displayed, so that the workability and operability of the centrifuge can be improved.
