Abstract

A centrifuge including a rotor, a rotor chamber having an opening, a motor, a door configured to close the opening, an input/output unit configured to receive an input of an operating condition and to display an operating status, and a housing accommodating therein the rotor, the rotor chamber, the motor, the door and the input/output unit, wherein the housing has the opening at an upper surface thereof, wherein a light emitting part having a horizontal width longer than the opening is provided in the vicinity of a corner portion at which the upper surface and a front surface of the housing intersect with each other or in the vicinity of a front side of the opening, and wherein a light emitting form of the light emitting part is configured to be changed depending on the operating status.

Claims (21)

1. A centrifuge comprising:

a rotor;

a rotor chamber accommodating therein the rotor and having an opening;

a motor configured to rotate the rotor;

a door configured to close the opening of the rotor chamber;

an input/output unit configured to receive an input of an operating condition and to display an operating status; and

a housing inlcuding the rotor, the rotor chamber, the motor, the door and the input/output unit,

wherein the housing has the opening at an upper surface thereof,

wherein a light emitting part having a horizontal width longer than the opening is provided in the vicinity of a corner portion at which the upper surface and a front surface of the housing intersect with each other or in the vicinity of a front side of the opening, and

wherein a light emitting form of the light emitting part is configured to be changed depending on the operating status of the centrifuge,

wherein a combination of an emission color, a brightness and a light emitting pattern of LEDs is allotted in correspondence to an operation of the centrifuge, and

wherein a light emitting form indicating at least one operating status of stop, acceleration, running at set speed and deceleration of the rotor is configured to be different from a light emitting form indicating abnormality in the centrifuge.

2. The centrifuge according to claim 1 , wherein the light emitting part is provided between the opening and the front surface of the housing.

3. The centrifuge according to claim 1 , wherein the light emitting part is provided at the front side of the opening so that a longitudinal direction thereof is positioned horizontally, and

wherein the light emitting part is arranged so that a position of a center of the rotor in a left-right direction and a position of a center of the light emitting part in the left-right direction coincide with each other.

4. The centrifuge according to claim 1 , wherein the light emitting part includes, the LEDs arranged inside the housing, and a transparent or semi-transparent transmission part or a window part provided in the vicinity of the corner portion of the housing and enabling light from the LEDs to penetrate therethrough.

5. The centrifuge according to claim 4 , wherein the light emitting part is configured by the LEDs capable of color display or a plurality of different LEDs of a plurality of different colors.

6. The centrifuge according to claim 4 , wherein the light emitting part is arranged so that illumination by the LEDs includes light emission components in a front direction and an upper direction from the housing, and

wherein an illumination angle within a plane including upper, lower, front and rear directions is larger than 0° and smaller than 90° (upper side in a vertical direction) with reference to a horizontal forward direction from the housing.

7. The centrifuge according to claim 6 , wherein the illumination angle is equal to or larger than 30° and equal to or smaller than 60°.

8. The centrifuge according to claim 1 , wherein the light emitting form of the light emitting part, which corresponds to an operation of the centrifuge, is configured so that it can be arbitrarily changed by a user.
