Abstract

With this analysis device, air that has been heated by a heater is blown by a fan in the direction of an analysis receptacle rotary driver and an analysis receptacle that is rotationally driven by the analysis receptacle rotary driver. The analysis receptacle rotary driver rotates the analysis receptacle within the analysis chamber in the same direction as the direction of air flow produced by the fan.

Claims

1. An analysis device, comprising:

an analysis chamber inside of which an analysis receptacle is positioned;

a fan positioned inside the analysis chamber and configured to blow air at the analysis receptacle so that the air circulates in a circular manner along a surface on which the analysis receptacle is positioned in the analysis chamber;

a heater configured to heat the air blown from the fan at the analysis receptacle; and

an analysis receptacle rotary driver positioned a specific distance away from the fan in a blowing direction of the fan inside the analysis chamber, and configured to rotate the analysis receptacle in a same direction as a direction of air flow formed by the fan,

wherein the analysis chamber is defined by linking a first round part that defines a cylindrical space in which the fan is housed, and a second round part that defines a cylindrical space in which the analysis receptacle rotary driver is housed, and

wherein a radius of the second round part is larger than a radius of the first round part.

2. The analysis device according to claim 1,

wherein the first round part is positioned around a circle having a center which is a rotational axis of the fan, and

wherein the second round part is positioned around a circle having a center which is a rotational axis of the analysis receptacle rotary driver.

3. The analysis device according to claim 1,

wherein the analysis chamber has an analysis receptacle insertion opening positioned at the second round part, and

wherein an analysis receptacle loading tray is positioned so as to be able to move in and out of the analysis receptacle insertion opening.
