Description

The present invention relates to a constant temperature and humidity device.

A constant temperature and humidity device is a device provided with a constant temperature and humidity bath that maintains constant temperature and humidity. For example, in the thermo-hygrostat, weighing using an electronic balance or the like, environmental tests, production control of dyes and pigments, cultivation of organisms, and the like are performed.

In such weighing, environmental tests, etc., there are cases where the influence of wind must be considered in addition to the influence of temperature and humidity. For example, when weighing with an electronic balance, the weight may change due to the influence of wind. In addition, when weighing powder with an electronic balance, the powder may be blown up by the wind. In this way, in the constant temperature and humidity chamber, there are cases where an environment close to no wind is required.

For example, Patent Literature 1 describes a rectangular parallelepiped main body having a plurality of first openings on the wall surface and a shield having a plurality of second openings on the wall surface as the inner tank arranged inside the constant temperature and humidity chamber. A small gap is formed by attaching a shielding plate to the wall surface provided with the plate and the first opening so that the first opening and the second opening slightly overlap to form a minute gap between the wall surface and the shielding plate. An inner tank is disclosed comprising means. In the constant temperature and humidity chamber of Patent Document 1, the inside of the inner tank main body and the outside of the inner tank main body communicate with each other through a minute gap between the wall surface and the shielding plate, and by allowing air to pass through the gap, the air is used as a medium to control the temperature and humidity inside the inner tank body. In addition, since the gap is small, the inside of the inner tank main body is hardly affected by the wind outside the inner tank main body, and an almost windless environment can be created.

Preferred embodiments of the present invention will be described in detail below with reference to the drawings. It should be noted that the embodiments described below do not unduly limit the scope of the invention described in the claims. Moreover, not all the configurations described below are essential constituent elements of the present invention.

1. First Embodiment 1.1. Configuration of Constant Temperature and Humidity Apparatus First, the temperature and humidity apparatus according to the first embodiment will be described with reference to the drawings. FIG. 1 is a perspective view schematically showing a constant temperature and humidity device 100 according to the first embodiment. FIG. 2 is a plan view schematically showing the upper surface 11 of the container 10 of the constant temperature and humidity device 100 according to the first embodiment. 3 and 4 are cross-sectional views schematically showing the constant temperature and humidity device 100 according to the first embodiment. 3 is a sectional view taken along line III-III of FIG. 2, and FIG. 4 is a sectional view taken along line IV-IV of FIG.

The constant temperature and humidity device 100 includes a container 10, a shielding plate 20, a radiation plate 30, a metal plate 40, a shielding wall 50, and an outer frame 60, as shown in FIGS.

The container 10 is a thermo-hygrostat having a space maintained at constant temperature and humidity. The container 10 has a first chamber 10a and a second chamber 10b.

A blowout port 12 and a discharge port 14 are connected to the first chamber 10a. The outlet 12 and the outlet 14 are provided on the upper surface 11 of the container 10 . The outlet 12 and the outlet 14 are connected to an air conditioner (not shown). The outlet 12 and the air conditioner are connected by a pipe 16a, and the outlet 14 and the air conditioner are connected by a pipe 16b.

Air conditioners supply temperature and humidity regulated air. Air whose temperature and humidity have been adjusted by the air conditioner is blown out from the outlet 12 . Here, a case where air whose temperature and humidity are adjusted is blown out from the blowing port 12 will be described, but the gas blown out from the blowing port 12 is not limited to air. For example, an inert gas such as nitrogen or argon, the temperature and humidity of which are adjusted, may be used as the gas to be blown from the blowing port 12 .

The first chamber 10a is, for example, a space partitioned by the inner wall of the container 10, the metal plate 40, and the outer frame 60. The first room 10a is a space for adjusting the environment of the second room 10b. A shielding plate 20 and a radiation plate 30 are accommodated in the first chamber 10a.

The second chamber 10b is connected to the first chamber 10a. The second chamber 10b is maintained at constant temperature and humidity. In addition, the second chamber 10b is maintained in an almost windless environment. For example, the second chamber 10b is maintained at a wind speed of 10 cm/s or less.

The second chamber 10b is, for example, a space for weighing using an electronic balance or the like, environmental tests, culturing of organisms, and the like. As shown in FIG. 1, the container 10 is provided with an opening 18 for putting a hand in and out of the second chamber 10b. The opening 18 is closed with, for example, a silicone rubber sheet or the like. The silicone rubber sheet has a notch for inserting and removing the hand. In the constant temperature and humidity device 100, the user can put his or her hand through the opening 18 and work in the second chamber 10b.

The shielding plate 20 is arranged below the outlet 12 . The shielding plate 20 is arranged between the outlet 12 and the radiation plate 30 . By arranging the shielding plate 20, the air blown out from the outlet 12 does not hit the radiation plate 30 directly. As shown in FIG. 2, the shielding plate 20 is provided from the outlet 12 to the outlet 14 in plan view. As shown in FIG. 3, the shielding plate 20 has a shape with bent ends.

The shield plate 20 has a bottom surface portion 22 and a wall surface portion 24 perpendicular to the bottom surface portion 22 . The air blown out from the blowout port 12 hits the bottom surface portion 22, crosses the wall surface portion 24, and flows to the radiation plate 30 in the lower stage. The shield plate 20 can change the flow of air blown out from the blowout port 12. - 特許庁

The material of the shield plate 20 is not particularly limited. For example, the shielding plate 20 may be made of metal fibers, similar to the radiation plate 30 described later. In this case, the density of the metal fibers forming the shielding plate 20 is higher than the density of the metal fibers forming the radiation plate 30 . The shield plate 20 may be, for example, a metal plate.

The radiation plate 30 is arranged between the shielding plate 20 and the metal plate 40 . Radiation plate 30 is fixed to the inner wall of container 10 . Radiation plate 30 is heated or cooled by the air blown out from blowout port 12 . The radiation plate 30 uses radiation to adjust the temperature of the second chamber 10b. Specifically, the radiation plate 30 reaches the same temperature as the air blown from the blowing port 12, and adjusts the temperature of the second chamber 10b to the same temperature as the air by using radiation. do. The air that has passed through the radiation plate 30 passes through the plurality of through holes 42 of the metal plate 40 and flows into the second chamber 10b.

The radiation plate 30 is made of metal fiber. The radiation plate 30 is, for example, a plate-shaped metal fiber. A metal fiber is a fibrous form of metal. The metal fiber is obtained, for example, by entangling metal threads with a diameter of about several μm and compression-molding them. Metal fibers forming the radiation plate 30 are, for example, aluminum. Aluminum has high thermal conductivity, is resistant to corrosion, and is readily available. The metal fibers forming the radiation plate 30 have a weight of about 1100 g/m ² per square meter, for example. The thickness of the radiation plate 30 is, for example, several millimeters to several centimeters.

The material of the metal fibers forming the radiation plate 30 is not particularly limited as long as it is a metal with high thermal conductivity. Materials of the metal fibers forming the radiation plate 30 are, for example, gold, silver, tungsten, copper, beryllium, hafnium, rhodium, magnesium, molybdenum, zinc, or alloys thereof.

The radiation plate 30 has a flat portion 32 parallel to the upper surface 11 of the container 10 and an inclined portion 34 inclined with respect to the upper surface 11 of the container 10, as shown in FIG. The inclined portion 34 faces the front surface of the container 10 . Since the radiation plate 30 has the flat portion 32 and the inclined portion 34 facing in different directions, the air in the second chamber 10b can be efficiently heated or cooled.

The metal plate 40 partitions the first chamber 10a and the second chamber 10b. A plurality of through holes 42 are formed in the metal plate 40 . A plurality of through holes 42 communicate between the first chamber 10a and the second chamber 10b. The plurality of through-holes 42 allow the air that has passed through the radiation plate 30 to pass therethrough. As a result, air flows from the first chamber 10a to the second chamber 10b. The metal plate 40 is heated or cooled by air and also functions as a radiation plate that adjusts the temperature of the second chamber 10b.

The metal plate 40 is, for example, punching metal. Although the material of the metal plate 40 is not particularly limited, it is preferably a metal with high thermal conductivity.

The metal plate 40 is fixed to the container 10 via an outer frame 60 connected to the top of the container 10, as shown in FIG. The outer frame 60 extends from the top of the container 10 . Similarly, the radiation plate 30 and the shielding plate 20 may also be fixed to the container 10 via the outer frame 60 . The outer frame 60 may be, for example, a member integrated with the metal plate 40 .

The shielding wall 50 is provided on the shielding plate 20 . The shielding wall 50 is provided so as to close the gap between the shielding plate 20 and the container 10 . The shielding wall 50 can prevent the air blown out from the outlet 12 from moving along the shielding plate 20 and being discharged from the outlet 14 .

1.2. Operation of Constant Temperature and Humidity Device FIGS. 5 to 7 are diagrams for explaining air flow in the constant temperature and humidity device 100. FIG.

The air whose temperature and humidity have been adjusted by the air conditioner blows out from the outlet 12 and hits the shielding plate 20 in the first chamber 10a. Most of the air hitting the shielding plate 20 goes around the shielding plate 20 and flows to the lower radiation plate 30 . As a result, the entire radiation plate 30 can be exposed to air. If the shielding plate 20 is made of metal fiber, part of the air that hits the shielding plate 20 passes through the shielding plate 20 and flows to the radiation plate 30 .

Since the second chamber 10b has a negative pressure, the air that hits the radiation plate 30 passes through the radiation plate 30. As shown in FIG. Since the radiation plate 30 is made of metal fibers, the direction of air flow changes when passing through the radiation plate 30, as shown in FIG. Therefore, the air that has passed through the radiation plate 30 is decelerated as it passes through the radiation plate 30 . By passing the air through the radiation plate 30 in this manner, the air is decelerated and the air flows out from the entire lower surface of the radiation plate 30 . As a result, air with a wind speed close to no wind flows out from the entire lower surface of the radiation plate 30 .

Moreover, since the radiation plate 30 is made of metal fibers with high thermal conductivity, the temperature of the radiation plate 30 becomes equal to the temperature of the air as the air passes through the radiation plate 30 . That is, the radiation plate 30 is heated or cooled by being exposed to temperature-controlled air. Specifically, when the temperature of the air passing through the radiation plate 30 is higher than the temperature of the radiation plate 30, the radiation plate 30 is heated. Moreover, when the temperature of the air passing through the radiation plate 30 is lower than the temperature of the radiation plate 30, the radiation plate 30 is cooled. Since the radiation plate 30 is made of metal fibers, heat can be efficiently exchanged between the air and the radiation plate 30 when the air passes through the radiation plate 30 . Since temperature-controlled air is supplied to the constant temperature and humidity device 100, the temperature of the radiation plate 30 is kept constant.

The air that has passed through the radiation plate 30 flows to the lower metal plate 40 . A plurality of through-holes 42 are provided in the metal plate 40, and the air that has passed through the radiation plate 30 passes through the plurality of through-holes 42, thereby making the wind speed distribution uniform. The air that has passed through the plurality of through holes 42 flows into the second chamber 10b. In this way, the air blown out from the blowout port 12 flows into the second chamber 10b at a near zero wind speed by the shielding plate 20, the radiation plate 30, and the metal plate 40. FIG.

As shown in FIG. 6 , part of the air blown out from the blowout port 12 travels along the shielding plate 20 toward the discharge port 14 and hits the shielding wall 50 . The air hitting the shielding wall 50 goes around the shielding plate 20 and flows to the radiation plate 30 . Thus, the shielding wall 50 can block the flow of air discharged from the outlet 14 without passing through the radiation plate 30 from the outlet 12 . Thereby, the time for which the air stays in the first chamber 10a can be lengthened. A part of the air blown out from the blowout port 12 and flowing in the first chamber 10 a is discharged from the discharge port 14 .

1.3. Functions and Effects The constant temperature and humidity apparatus 100 includes a container 10 having a first chamber 10a connected to an air outlet 12 whose temperature and humidity are adjusted, and a second chamber 10b connected to the first chamber 10a; and a radiation plate 30 housed in the first chamber 10a and for adjusting the temperature of the second chamber 10b. The radiation plate 30 is made of metal fibers, and the radiation plate 30 is heated or cooled by being exposed to air whose temperature and humidity are adjusted. flows into chamber 10b.

Thus, in the constant temperature and humidity apparatus 100, the air whose temperature and humidity are adjusted passes through the radiation plate 30 and flows into the second chamber 10b. The room 10b can be kept in a nearly windless state. Further, since the temperature of the second chamber 10b can be controlled by the radiation plate 30 and the air flowing through the second chamber 10b, the temperature of the second chamber 10b can be adjusted efficiently. In this way, the constant temperature and humidity device 100 can realize a constant temperature and humidity environment with almost no wind.

The constant temperature and humidity device 100 includes a metal plate 40 having a plurality of through-holes 42 for passing air that has passed through the radiation plate 30 . The metal plate 40 partitions the first chamber 10a and the second chamber 10b, and the plurality of through holes 42 communicate the first chamber 10a and the second chamber 10b. Therefore, in the constant temperature and humidity device 100, the wind speed distribution of the air flowing through the second chamber 10b can be made uniform.

The constant temperature and humidity device 100 includes a shielding plate 20 arranged between the blowing port 12 and the radiation plate 30 , and the air blown out from the blowing port 12 hits the shielding plate 20 and flows to the radiation plate 30 . Therefore, in the constant temperature and humidity device 100, the entire radiation plate 30 can be exposed to air.

For example, without the shielding plate 20 , most of the air blown from the blowout port 12 hits the area of the radiation plate 30 located below the blowout port 12 . As a result, the wind velocity distribution of the air flowing through the second chamber 10b cannot be made uniform. On the other hand, in the constant temperature and humidity apparatus 100, the shielding plate 20 allows air to hit the entire radiation plate 30, so that the wind speed distribution of the air flowing in the second chamber 10b can be made uniform.

In the constant temperature and humidity device 100, the container 10 is provided with an opening 18 for putting a hand in and out of the second chamber 10b. Therefore, in the constant temperature and humidity device 100, the operator can work in an environment where the constant temperature and humidity are maintained and there is almost no wind.

FIG. 8 is a graph showing temporal changes in the temperature Tin and the humidity Hin in the second chamber 10b of the constant temperature and humidity device 100. As shown in FIG. The graph shown in FIG. 8 also shows how the external temperature Tout and humidity Hout change. The unit of the vertical axis of the graph shown in FIG. 8 is "%" for humidity and "°C" for temperature. FIG. 9 is a graph showing temporal changes in wind speed inside the second chamber 10b of the constant temperature and humidity apparatus 100. As shown in FIG. The data shown in FIGS. 8 and 9 are data when air having a temperature of 25° C. and a humidity of 57.6% is sent from the air conditioner to the constant temperature and humidity apparatus 100 at a speed of 2 m/s.

As shown in FIG. 8, even if the outside temperature Tout and the outside humidity Hout fluctuate, the temperature Tin and the humidity Hin of the second chamber 10b are kept constant. Also, as shown in FIG. 9, it can be seen that the wind velocity in the second chamber 10b is maintained at 10 cm/s or less.

Thus, it can be seen that the constant temperature and humidity apparatus 100 can realize a constant temperature and humidity environment with almost no wind.

1.4. MODIFIED EXAMPLE FIG. 10 is a cross-sectional view schematically showing a constant temperature and humidity device 110 according to a modified example of the first embodiment. Hereinafter, in the constant temperature and humidity apparatus 110 according to the modified example of the first embodiment, members having the same functions as the constituent members of the constant temperature and humidity apparatus 100 according to the first embodiment are denoted by the same reference numerals, and the details thereof are as follows. detailed description is omitted.

The constant temperature and humidity device 110 does not have the outlet 14 as shown in FIG. In the constant temperature and humidity device 110, for example, the air blown from the outlet 12 flows from the first chamber 10a to the second chamber 10b and is discharged from the opening 18 shown in FIG.

In the constant temperature and humidity device 110, similarly to the above-described constant temperature and humidity device 100, it is possible to realize a constant temperature and humidity environment and an almost windless environment.

2. Second Embodiment Next, a thermo-hygrostat according to a second embodiment will be described with reference to the drawings. FIG. 11 is a cross-sectional view schematically showing a constant temperature and humidity device 200 according to the second embodiment. Note that FIG. 11 corresponds to FIG. Hereinafter, in the constant temperature and humidity apparatus 200 according to the second embodiment, the members having the same functions as the constituent members of the temperature and humidity apparatus 100 according to the first embodiment are denoted by the same reference numerals, and detailed description thereof will be given. omitted.

In the constant temperature and humidity device 200, a rectifying plate 202 is provided at the outlet 12, as shown in FIG. The rectifying plate 202 rectifies the air blown out from the outlet 12 . The straightening plate 202 straightens the air so that the air hits the entire radiation plate 30 . Thus, the current plate 202 can change the flow of air.

In the outlet 12, the diameter D4 on the downstream side of the air flow is larger than the diameter D2 on the upstream side of the air flow. As a result, the air flow can be changed so that the entire radiation plate 30 is exposed to the air.

The constant temperature and humidity apparatus 200 can realize an environment of constant temperature and humidity and almost no wind, like the constant temperature and humidity apparatus 100 described above. Furthermore, since the constant temperature and humidity device 200 includes the rectifying plate 202 that is provided at the outlet 12 and rectifies the temperature- and humidity-controlled air, the air velocity distribution of the air flowing into the second chamber 10b can be made more uniform.

3. Third Embodiment Next, a thermo-hygrostat according to a third embodiment will be described with reference to the drawings. FIG. 12 is a cross-sectional view schematically showing a constant temperature and humidity device 300 according to the third embodiment. In addition, Fig. 1
2 corresponds to FIG. In the temperature and humidity device 300 according to the third embodiment, members having the same functions as those of the temperature and humidity device 100 according to the first embodiment and the temperature and humidity device 200 according to the second embodiment will be described below. The same reference numerals are given, and detailed description thereof is omitted.

The constant temperature and humidity device 300 has a plurality of radiation plates, as shown in FIG. The illustrated example includes a first radiation plate 30a, a second radiation plate 30b (an example of another radiation plate), and a third radiation plate 30c (an example of another radiation plate).

The configurations of the first radiation plate 30a, the second radiation plate 30b, and the third radiation plate 30c are the same as the configuration of the radiation plate 30 described above. That is, the first radiation plate 30a is made of metal fiber, and the first radiation plate 30a is heated or cooled by air passing through the first radiation plate 30a. Also, the second radiation plate 30b is made of metal fiber, and the second radiation plate 30b is heated or cooled by air passing through the second radiation plate 30b. The third radiation plate 30c is made of metal fiber, and the third radiation plate 30c is heated or cooled by air passing through the third radiation plate 30c.

The density of the metal fibers forming the first radiation plate 30a is higher than the density of the metal fibers forming the second radiation plate 30b. The density of the metal fibers forming the second radiation plate 30b is higher than the density of the metal fibers forming the third radiation plate 30c.

The first radiation plate 30a, the second radiation plate 30b, and the third radiation plate 30c are arranged in this order from the metal plate 40 side. That is, the distance between the first radiation plate 30a and the metal plate 40 is smaller than the distance between the second radiation plate 30b and the metal plate 40 and the distance between the third radiation plate 30c and the metal plate 40. . The second radiation plate 30 b and the third radiation plate 30 c are arranged between the first radiation plate 30 a and the outlet 12 .

The first radiation plate 30a and the second radiation plate 30b are separated from each other. Also, the second radiation plate 30b and the third radiation plate 30c are separated from each other. The first radiation plate 30a and the second radiation plate 30b may be in contact, and the second radiation plate 30b and the third radiation plate 30c may be in contact.

FIG. 13 is a diagram for explaining the air flow in the first radiation plate 30a, the second radiation plate 30b, and the third radiation plate 30c.

The air blown out from the blowout port 12 passes through the third radiation plate 30c and hits the second radiation plate 30b. The air hitting the second radiation plate 30b passes through the second radiation plate 30b and hits the first radiation plate 30a. The air hitting the first radiation plate 30a passes through the first radiation plate 30a, hits the metal plate 40, passes through the plurality of through holes 42, and flows into the second chamber 10b.

Here, since the density of the metal fibers forming the third radiation plate 30c is the lowest, air diffusion is the lowest and air transmittance is the highest. Since the density of the metal fibers forming the first radiation plate 30a is the highest, air diffusion is the largest and air transmittance is the lowest. Therefore, as the air passes through the third radiation plate 30c, the second radiation plate 30b, and the first radiation plate 30a in this order, the air is gradually decelerated and gradually diffused. As a result, the second chamber 10b can be kept in a nearly windless state. Furthermore, the wind velocity distribution of the air flowing through the second chamber 10b can be made uniform.

The constant temperature and humidity device 300 does not need to have the shield plate 20 as shown in FIG.

The constant temperature and humidity apparatus 300 can realize an environment of constant temperature and humidity and almost no wind, like the constant temperature and humidity apparatus 100 described above.
