Description

本考案は、分析装置に関し、特にＩＣＰ発光分光分析装置に関する。   The present invention relates to an analyzer, and more particularly to an ICP emission spectroscopic analyzer.

ＩＣＰ発光分光分析装置では、試料をプラズマ炎に導入して励起発光させ、その発光光を回折格子で波長分散させて光検出器で検出することにより、発光スペクトルを取得する。そして、発光スペクトルに現れているスペクトル線（輝線スペクトル）の波長の種類から試料中に含有されている元素の定性分析（同定）を行い、さらにその輝線スペクトルの強度からその元素の定量分析を行っている（例えば、特許文献１参照）。   In an ICP emission spectroscopic analyzer, a sample is introduced into a plasma flame to cause excitation light emission, and the emission spectrum is obtained by wavelength-dispersing the emitted light with a diffraction grating and detecting with a photodetector. Then, the qualitative analysis (identification) of the element contained in the sample is performed from the wavelength type of the spectral line (bright line spectrum) appearing in the emission spectrum, and the element is quantitatively analyzed from the intensity of the bright line spectrum. (For example, refer to Patent Document 1).

図６は、ＩＣＰ発光分光分析装置の一例を示す斜視図であり、図７は、図６に示すＩＣＰ発光分光分析装置の断面図である。なお、地面に水平な一方向をＸ方向（左右方向）とし、地面に水平でＸ方向と垂直な方向をＹ方向（前後方向）とし、Ｘ方向とＹ方向とに垂直な方向をＺ方向（上下方向）とする。
ＩＣＰ発光分光分析装置１０１は、直方体形状の筐体１０を備え、筐体１０の内部には、プラズマ炎を形成するための発光分光分析用プラズマトーチや発光光を検出する測光部や高周波電流を供給するためのプラズマ用高周波電源等の部材（発熱部）１４や、発光分光分析用プラズマトーチ等を冷却する冷却用ファン１３等が配置されている。 FIG. 6 is a perspective view showing an example of an ICP emission spectroscopic analyzer, and FIG. 7 is a cross-sectional view of the ICP emission spectroscopic analyzer shown in FIG. One direction horizontal to the ground is defined as the X direction (left-right direction), the direction horizontal to the ground and perpendicular to the X direction is defined as the Y direction (front-rear direction), and the direction perpendicular to the X direction and the Y direction is defined as the Z direction ( Vertical direction).
The ICP emission spectroscopic analysis apparatus 101 includes a rectangular parallelepiped housing 10, and the housing 10 includes an emission spectroscopic analysis plasma torch for forming a plasma flame, a photometric unit for detecting emitted light, and a high-frequency current. A member (heat generating portion) 14 such as a high frequency power source for plasma for supplying, a cooling fan 13 for cooling a plasma torch for emission spectral analysis, and the like are disposed.

このようなＩＣＰ発光分光分析装置１０１では、高周波電流を供給する際には高周波回路基板の素子等が発熱するため、冷却用ファン１３を回転させることによって筐体１０の底面の吸気口１１から内部に空気を吸気して流通させて排気口１２から排出することで、高周波回路基板の素子等に発生する熱を放熱している。   In such an ICP emission spectroscopic analysis apparatus 101, when a high-frequency current is supplied, elements of the high-frequency circuit board generate heat, so that the cooling fan 13 is rotated to rotate the cooling fan 13 from the inlet 11 on the bottom surface of the housing 10 to the inside. The air generated in the air is circulated and discharged from the exhaust port 12 to dissipate heat generated in the elements of the high-frequency circuit board.

ここで、図８は、図６に示すＩＣＰ発光分光分析装置の底面斜視図である。筐体１０の底面には、長方形の吸気口１１が形成され、吸気口１１には、網状のエアフィルタ２０が金具１５で保持されている。また、筐体１０の背面には、図７に示すように長方形の排気口１２が形成されている。そして、筐体１０の底面の四隅には、それぞれ円柱形状の脚部３０が設けられている。これにより、筐体１０の底面と床との間の距離Ｙ１が形成されている。 Here, FIG. 8 is a bottom perspective view of the ICP emission spectroscopic analyzer shown in FIG. A rectangular air inlet 11 is formed on the bottom surface of the housing 10, and a net-like air filter 20 is held by a metal fitting 15 in the air inlet 11. Further, a rectangular exhaust port 12 is formed on the rear surface of the housing 10 as shown in FIG. In addition, columnar leg portions 30 are provided at the four corners of the bottom surface of the housing 10. Thus, the distance Y 1 between the bottom and the floor of the housing 10 is formed.

特開平１１−１０１７４８号公報JP-A-11-101748

ところで、上述したようなＩＣＰ発光分光分析装置１０１では、筐体１０の底面から内部に空気を吸気する構造であるため、筐体１０の底面と床との間の距離Ｙ１が必要であるが、距離Ｙ１は、ＩＣＰ発光分光分析装置１０１自体のサイズを小さくするために極力小さい方がよい。しかしながら、距離Ｙ１を小さくしたときに、筐体１０の底面と床との間に、空気の流れにより異物等（特に紙）が入り込むことがあり、入り込んだ紙等が吸気口１１に吸い付くことがあった。その結果、筐体１０内部の温度が上昇し、装置に不具合が発生していた。
そこで、本考案は、筐体の底面と床との間に紙等が入り込んで、吸気口に吸い付いたとしても内部を冷却することができる分析装置を提供することを目的とする。 By the way, since the ICP emission spectroscopic analyzer 101 as described above has a structure in which air is sucked into the inside from the bottom surface of the housing 10, a distance Y 1 between the bottom surface of the housing 10 and the floor is necessary. The distance Y 1 should be as small as possible in order to reduce the size of the ICP emission spectroscopic analyzer 101 itself. However, when reducing the distance Y 1, between the bottom and the floor of the housing 10, there is foreign matter or the like (in particular paper) enters the air flow, intruded paper or the like stick to the intake port 11 There was a thing. As a result, the temperature inside the housing 10 has risen, and a malfunction has occurred in the apparatus.
Therefore, an object of the present invention is to provide an analyzer that can cool the interior even if paper or the like enters between the bottom surface and the floor of the housing and sucks into the intake port.

上記課題を解決するためになされた本考案の分析装置は、筐体と、前記筐体の内部に配置された発熱部及びファンとを備え、前記筐体の底面には、吸気口が形成されるとともに、当該底面と床との間に空間を設けるための脚部が形成されている分析装置であって、前記吸気口を、空間をあけて覆うように取り付けられた空間形成部材を備え、前記空間形成部材には、開口部が形成されるようにしている。   An analyzer of the present invention made to solve the above problems includes a housing, a heat generating unit and a fan arranged inside the housing, and an air inlet is formed on a bottom surface of the housing. And an analyzer in which a leg for providing a space between the bottom surface and the floor is formed, and includes a space forming member attached so as to cover the air intake opening. An opening is formed in the space forming member.

本考案の分析装置によれば、正常時では、空間形成部材の下面と床との間を通った空気が、空間形成部材の開口部を通過した後、吸気口から筐体の内部を通って排気口へ流通する。また、空間形成部材の上面と筐体の底面との間を通った空気は、直接吸気口から筐体の内部を通って排気口へ流通する。   According to the analyzer of the present invention, under normal conditions, the air passing between the lower surface of the space forming member and the floor passes through the opening of the space forming member and then passes through the inside of the housing from the air inlet. Circulate to the exhaust port. Further, the air that has passed between the upper surface of the space forming member and the bottom surface of the housing flows directly from the intake port through the interior of the housing to the exhaust port.

一方、筐体の底面と床との間に紙等が入り込み、紙等が空間形成部材の下面に吸い付けられたとき（異常発生時）には、空間形成部材の下面と床との間を通った空気は、空間形成部材の開口部を通過することはできないが、空間形成部材の上面と筐体の底面との間を通った空気が、吸気口から筐体の内部を通って排気口へ流通する。つまり、筐体内部を空気が流通する。   On the other hand, when paper or the like enters between the bottom surface of the housing and the floor and the paper or the like is attracted to the lower surface of the space forming member (when an abnormality occurs), the space between the lower surface of the space forming member and the floor is The air that has passed cannot pass through the opening of the space forming member, but the air that has passed between the top surface of the space forming member and the bottom surface of the housing passes through the interior of the housing from the air intake port to the exhaust port. Circulate to That is, air circulates inside the housing.

以上のように、本考案の分析装置によれば、筐体の底面と床との間に紙等が入り込んで、吸気口に吸い付いたとしても、別の空間からの流路が存在するため、空気の吸入が妨げられず、その結果、内部を冷却することができる。   As described above, according to the analyzer of the present invention, even if paper or the like enters between the bottom surface and the floor of the housing and sucks into the intake port, a flow path from another space exists. Inhalation of air is not hindered, and as a result, the inside can be cooled.

以下、本考案の実施形態について図面を用いて説明する。なお、本考案は、以下に説明するような実施形態に限定されるものではなく、本考案の趣旨を逸脱しない範囲で種々の態様が含まれることはいうまでもない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments described below, and it goes without saying that various aspects are included without departing from the spirit of the present invention.

図１は、本考案の実施形態に係るＩＣＰ発光分光分析装置の一例を示す斜視図であり、図２は、図１に示すＩＣＰ発光分光分析装置の断面図であり、図３は、図１に示すＩＣＰ発光分光分析装置の底面斜視図である。なお、ＩＣＰ発光分光分析装置１０１と同様のものについては、同じ符号を付している。
ＩＣＰ発光分光分析装置１は、直方体形状（例えば８７ｃｍ×６４ｃｍ×５９ｃｍ）の筐体１０を備え、筐体１０の内部には、プラズマ炎を形成するための発光分光分析用プラズマトーチや発光光を検出する測光部や高周波電流を供給するためのプラズマ用高周波電源等の部材（発熱部）１４や、発光分光分析用プラズマトーチ等を冷却する冷却用ファン１３等が配置されている。 FIG. 1 is a perspective view showing an example of an ICP emission spectroscopic analysis apparatus according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the ICP emission spectroscopic analysis apparatus shown in FIG. 1, and FIG. It is a bottom perspective view of the ICP emission spectroscopic analyzer shown in FIG. In addition, the same code | symbol is attached | subjected about the thing similar to the ICP emission-spectral-analysis apparatus 101. FIG.
The ICP emission spectroscopic analysis apparatus 1 includes a casing 10 having a rectangular parallelepiped shape (for example, 87 cm × 64 cm × 59 cm), and an emission spectroscopic analysis plasma torch for generating a plasma flame or emission light is formed inside the casing 10. A member (heating unit) 14 such as a photometric unit to detect, a high frequency power source for plasma for supplying a high frequency current, a cooling fan 13 for cooling a plasma torch for emission spectroscopic analysis, and the like are arranged.

筐体１０の底面には、長方形（例えば２４ｃｍ×４６ｃｍ）の吸気口１１が形成され、吸気口１１には、網状のエアフィルタ２０が金具１５で保持されている。また、筐体１０の背面には、長方形（例えば２０ｃｍ×２３ｃｍ）の排気口１２が形成されている。そして、筐体１０の底面の四隅には、それぞれ円柱形状（例えば高さ５ｃｍ）の脚部３０が設けられている。これにより、筐体１０の底面と床との間の距離Ｙ１（例えば７ｃｍ）が形成されている。 A rectangular (for example, 24 cm × 46 cm) air inlet 11 is formed on the bottom surface of the housing 10, and a net-like air filter 20 is held by the metal fitting 15 in the air inlet 11. A rectangular (for example, 20 cm × 23 cm) exhaust port 12 is formed on the back surface of the housing 10. And the leg part 30 of cylindrical shape (for example, height 5cm) is provided in the four corners of the bottom face of the housing | casing 10, respectively. Thus, the distance Y 1 between the bottom surface and the floor of the housing 10 (e.g., 7 cm) is formed.

空間形成部材４０は、第一空間形成部材４１と、第二空間形成部材４２とからなる。
第一空間形成部材４１は、板状体（例えば７９ｃｍ×１９ｃｍ×２ｃｍ）であり、その左右方向の中央領域（例えば２４ｃｍ×１４ｃｍ）には第一開口部４１ａが形成され、第一開口部４１ａは網状となっている。また、板状体の中央領域から離れた左端領域（例えば４ｃｍ×１０ｃｍ）及び右端領域（例えば４ｃｍ×１０ｃｍ）には、持ち手用開口部（第二開口部）４１ｂがそれぞれ形成されている。 The space forming member 40 includes a first space forming member 41 and a second space forming member 42.
The first space forming member 41 is a plate-like body (for example, 79 cm × 19 cm × 2 cm), and a first opening 41a is formed in a central region (for example, 24 cm × 14 cm) in the left-right direction, and the first opening 41a is formed. Is reticulated. Further, a handle opening (second opening) 41b is formed in a left end region (for example, 4 cm × 10 cm) and a right end region (for example, 4 cm × 10 cm) apart from the central region of the plate-like body.

そして、第一空間形成部材４１の左端部は筐体１０の左端部に取り付けられ、第一空間形成部材４１の右端部は筐体１０の右端部に取り付けられることで、エアフィルタ２０の下面から距離Ｙ２（例えば１．５ｃｍ）の位置に第一空間形成部材４１の上面が配置されるようになっている。このとき、第一空間形成部材４１の第一開口部４１ａが、吸気口１１の第一領域を覆うように配置される。 Then, the left end portion of the first space forming member 41 is attached to the left end portion of the housing 10, and the right end portion of the first space forming member 41 is attached to the right end portion of the housing 10, so that from the lower surface of the air filter 20. The upper surface of the first space forming member 41 is arranged at a position of distance Y 2 (for example, 1.5 cm). At this time, the first opening 41 a of the first space forming member 41 is disposed so as to cover the first region of the air inlet 11.

また、第二空間形成部材４２も、第一空間形成部材４１と同様の構造をしており、第二空間形成部材４２の第一開口部４２ａが、吸気口１１の第一領域から離れた吸気口１１の第二領域を覆うように配置されている。つまり、吸気口１１は、前後方向で交互に覆われたり覆われなかったりするようになっている。   In addition, the second space forming member 42 has the same structure as the first space forming member 41, and the first opening 42 a of the second space forming member 42 is inhaled away from the first region of the air inlet 11. It arrange | positions so that the 2nd area | region of the opening | mouth 11 may be covered. That is, the air inlets 11 are alternately covered or not covered in the front-rear direction.

このようなＩＣＰ発光分光分析装置１によれば、図２に示すように、冷却用ファン１３が回転することで、正常時では、第一空間形成部材４１の下面と床との間を通った空気は、第一空間形成部材４１の第一開口部４１ａを通過した後、吸気口１１から筐体１０の内部を通って排気口１２へ流通する。また、第一空間形成部材４１の上面と筐体１０の底面との間を通った空気は、直接吸気口１１から筐体１０の内部を通って排気口１２へ流通する。また、第二空間形成部材４２の下面と床との間を通った空気は、第二空間形成部材４２の第一開口部４２ａを通過した後、吸気口１１から筐体１０の内部を通って排気口１２へ流通する。また、第二空間形成部材４２の上面と筐体１０の底面との間を通った空気は、直接吸気口１１から筐体１０の内部を通って排気口１２へ流通する。   According to such an ICP emission spectroscopic analysis apparatus 1, as shown in FIG. 2, the cooling fan 13 rotates so that the normal space passes between the lower surface of the first space forming member 41 and the floor. After passing through the first opening 41 a of the first space forming member 41, the air flows from the intake port 11 through the inside of the housing 10 to the exhaust port 12. Further, the air that has passed between the upper surface of the first space forming member 41 and the bottom surface of the housing 10 flows directly from the intake port 11 through the interior of the housing 10 to the exhaust port 12. In addition, the air that has passed between the lower surface of the second space forming member 42 and the floor passes through the first opening 42 a of the second space forming member 42 and then passes through the interior of the housing 10 from the air inlet 11. It circulates to the exhaust port 12. Further, the air that has passed between the upper surface of the second space forming member 42 and the bottom surface of the housing 10 flows directly from the intake port 11 through the interior of the housing 10 to the exhaust port 12.

ところで、上述したように筐体１０の底面と床との間に、空気の流れにより紙Ｐが入り込むことがある。図４は、図１に示すＩＣＰ発光分光分析装置に紙Ｐが入り込んだ際の状態を示す断面図であり、図５は、図４とは異なる方向から見た場合の断面図である。図の通り、装置内に入り込んだ紙Ｐが、第一空間形成部材４１の第一開口部４１ａに吸い付けられている。このような場合に、本考案のＩＣＰ発光分光分析装置１によれば、冷却用ファン１３が回転することで、第一空間形成部材４１の下面と床との間を通った空気は、第一空間形成部材４１の第一開口部４１ａを通過することはできないが、第一空間形成部材４１の持ち手用開口部（第二開口部）４１ｂを通過した空気や、第一空間形成部材４１の上面と筐体１０の底面との間を通った空気が、吸気口１１から筐体１０の内部を通って排気口１２へ流通する。また、第二空間形成部材４２の下面と床との間を通った空気は、第二空間形成部材４２の第一開口部４２ａを通過した後、吸気口１１から筐体１０の内部を通って排気口１２へ流通する。また、第二空間形成部材４２の上面と筐体１０の底面との間を通った空気は、直接吸気口１１から筐体１０の内部を通って排気口１２へ流通する。   Incidentally, as described above, the paper P may enter between the bottom surface and the floor of the housing 10 due to the flow of air. 4 is a cross-sectional view showing a state when the paper P enters the ICP emission spectroscopic analysis apparatus shown in FIG. 1, and FIG. 5 is a cross-sectional view when viewed from a direction different from FIG. As illustrated, the paper P that has entered the apparatus is sucked into the first opening 41 a of the first space forming member 41. In such a case, according to the ICP emission spectroscopic analyzer 1 of the present invention, the cooling fan 13 rotates so that the air passing between the lower surface of the first space forming member 41 and the floor becomes the first. Although it cannot pass through the first opening 41 a of the space forming member 41, the air that has passed through the handle opening (second opening) 41 b of the first space forming member 41 or the first space forming member 41 Air passing between the upper surface and the bottom surface of the housing 10 flows from the intake port 11 through the interior of the housing 10 to the exhaust port 12. In addition, the air that has passed between the lower surface of the second space forming member 42 and the floor passes through the first opening 42 a of the second space forming member 42 and then passes through the interior of the housing 10 from the air inlet 11. It circulates to the exhaust port 12. Further, the air that has passed between the upper surface of the second space forming member 42 and the bottom surface of the housing 10 flows directly from the intake port 11 through the interior of the housing 10 to the exhaust port 12.

以上のように、本考案のＩＣＰ発光分光分析装置１によれば、筐体の底面と床との間に紙Ｐが入り込んで吸い付いたとしても、別の空間からの流路が存在するため、空気の吸入が妨げられず、その結果、内部の発熱部１４を冷却することができる。なお、測定が終了すれば、紙Ｐは第一空間形成部材４１の第一開口部４１ａから離れるので、そのときに紙Ｐを取り除けばよい。   As described above, according to the ICP emission spectroscopic analysis apparatus 1 of the present invention, even if the paper P enters and sucks between the bottom surface and the floor of the housing, there is a flow path from another space. Inhalation of air is not hindered, and as a result, the internal heat generating portion 14 can be cooled. When the measurement is completed, the paper P is separated from the first opening 41a of the first space forming member 41. Therefore, the paper P may be removed at that time.
