DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated container which is used under a high or low temperature condition having a large temperature difference from room temperature in a state in which an object is stored therein. The present invention relates to a heat insulating container for protecting stored items, and further relates to a measuring device using the heat insulating container.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional heat-insulating container 30 has a container body 32 having an access port 31 and a lid 33 for opening and closing the access port 31. Alternatively, the temperature recording unit 34 which is a precision machine that is protected from low temperature, for example, a failure that occurs due to a rapid temperature change.
And a layer filled with a heat insulating material D was provided around the inside of the container of the lid 33. Then, in a measuring device using the conventional heat insulating container 30, for example, the temperature measuring device 40, the temperature recording unit 34 is housed in the conventional heat insulating container 30 and protected from high or low temperature for a certain period of time. A continuous temperature sensor is positioned outside the heat insulating container 30 by a sensor code, and the temperature is measured under high or low temperature conditions. For example, when the conventional temperature measuring device 40 is used at a high temperature, the temperature recording unit 34 in the heat insulating container 30 is used.
After the start of measurement, the temperature of
After 0 minutes, the temperature of the temperature recording section 34 reaches 50 ° C. Therefore, in this case, it is necessary to finish the measurement before the temperature reaches the quality assurance temperature, for example, within 50 minutes until the temperature of the temperature recording unit 34 reaches 40 ° C. After the measurement is completed, the heat insulating material D
When the temperature measuring device 40 is immediately reused under a high temperature without removing the heat accumulated in the thermometer, the heat insulating effect of the heat insulating material D is reduced, and the temperature of the temperature recording unit 34 is quickly increased, and The container 30 cannot protect the temperature recording unit 34 from the high temperature for 10 minutes. Therefore, the heat insulating container 30
Before reuse, the heat accumulated in the heat insulating material D must be removed to return the heat insulating material D to normal temperature.

[0003]

In the conventional heat insulating container 30, if the heat insulating material D is thick and a large amount of heat insulating material D is used, the heat capacity of the whole heat insulating material D becomes large, so that the heat insulating effect is large. The temperature change rate of the temperature recording unit 34 is slowed down, and the temperature
May be used for about 50 minutes. However, after the temperature measurement, in order to reuse the temperature measuring device 40, it is necessary to return a large amount of the heat insulating material D to normal temperature. However, heat transfer from the heat insulating material D having a large heat capacity and a low heat conductivity does not occur. Because of the difficulty, it took about 60 minutes to reuse the temperature measuring device 40 after returning a large amount of the heat insulating material D to normal temperature.
On the other hand, when the amount of the heat insulating material D is reduced, the heat insulating material D
The heat capacity of the whole becomes small, the heat insulating effect of the heat insulating material D becomes weak, and the temperature of the temperature recording unit 34 rises from a normal temperature of 25 ° C. to 50 ° C. in a short time of 30 minutes. Therefore, after the measurement, the insulation D
Can be returned to room temperature in a short time of 30 minutes,
Although the temperature measurement device can be reused quickly,
On the other hand, since the temperature recording unit 34 is insulated for only 30 minutes, there is a disadvantage that the usable time of the temperature measuring device is as short as about 20 minutes. Thus, for convenience of use, in the above example, the temperature measuring device and the insulated container can be used for about 50 minutes, while the time required to reuse the temperature measuring device and the insulated container is about 20 minutes. It is preferable that the time is short. Therefore, an object of the present invention described in claims 1 to 4 is that an object stored in an insulated container is required to be able to be used again in an insulated container capable of protecting the object from high or low temperature for the same time as the conventional case. A great time is to provide an insulated container that can be shortened than before. An object of the invention according to claim 5 is to provide a measurement device that arranges a measurement result recording unit and a measurement unit at a high or low temperature to perform measurement, and protects the measurement result recording unit from a high or low temperature for the same time as before. It is an object of the present invention to provide a measuring device which can be used again after the measurement and can be used again after the measurement.

[0004]

According to a first aspect of the present invention, there is provided an insulated container for storing an object therein at a high temperature or a low temperature in a state where the object is housed therein and protecting the object from the high or low temperature. The container body has an insulated container body having an entrance / exit portion for the object, and heat insulation means for opening / closing the entrance / exit portion. The container body has an outer wall located outside the container and an inner wall located inside the container being continuous. It is a double structure, wherein the inside of the double structure is vacuum, and the heat insulating means is located outside the heat insulating container when the inlet / outlet is closed by the heat insulating means. Characterized by having an outer heat-insulating member that suppresses the transmission of heat, an inner heat-insulating member that is located toward the inside of the heat-resistant container and suppresses the transmission of heat, and heat storage means that is located between these two heat-insulating members. Created an insulated container.

According to a second aspect of the present invention, the apparatus further comprises a heat transfer means for facilitating the transfer of heat between the inner wall and the heat storage means when the inlet / outlet is closed by the heat insulating means. The insulated container described was created.

According to a third aspect of the present invention, the heat storage means has higher thermal conductivity than the heat insulating member and is separable from the heat insulating means. did.

According to a fourth aspect of the present invention, the heat storage means is made of a material having a larger heat capacity than the heat insulating member of the same volume. Created an insulated container.

According to a fifth aspect of the present invention, the heat insulation container according to any one of the first to fourth aspects is placed under a high temperature or a low temperature in a state where the measurement result recording section is housed inside the heat insulation container body. A measurement device that performs measurement in a state where the measurement result recording unit is protected from high or low temperature, wherein the measurement result recording unit includes the heat insulating container in a state where the access port is closed using the heat insulating unit. A measuring device characterized by being electrically connected to an external measuring unit was created.

As the heat insulating member, for example, a heat insulating material which is a material having a small heat transfer property can be used. As the heat insulating material, inorganic materials such as asbestos and glass wool can be used. Organic materials include various fibers, cork, and foam synthetic resin. Non-combustible insulation is safer to use at high temperatures, and heat resistant insulation with better heat resistance is more appropriate to use at high temperatures. The heat storage means is a means capable of storing heat. For example, a material having a higher specific heat than the heat insulating member and a higher heat conductivity than the heat insulating member can be used.

[0010]

According to the heat insulating container of the first aspect of the present invention, since the heat insulating container body has a vacuum double structure, objects in the heat insulating container are protected from high or low temperature outside the container. In addition, the heat transfer inside and outside the entrance is suppressed by the heat insulating member outside the heat insulating container. Further, since heat is stored in the heat storage means, the transfer of heat between the outer heat insulating member and the inner heat insulating member is suppressed, and therefore, a change in the temperature of an object in the heat insulating container due to the temperature outside the heat insulating container is suppressed. After the use of the insulated container, the container body separated from the object can be rapidly cooled or heated and quickly returned to room temperature. In addition, since it has a double structure, the temperature can be quickly returned to room temperature as compared with the case of a lump shape.

[0011] The heat insulating container having the structure described in claim 2 is
Since the transfer of heat between the inner wall and the heat storage means is promoted by the heat transfer means, a temperature change of an object in the heat insulating container due to the transfer of heat between the outer wall and the inner wall of the double structure of the heat insulating container body is suppressed. In the heat insulating container according to the third aspect, the heat storage means is separated from the heat insulating means after use, and the separated heat storage means has a higher thermal conductivity than the heat insulating member. Can be. In the heat insulating container having the configuration according to claim 4, the heat storage means is made of a material having a larger heat capacity than the heat insulating member having the same volume, that is, a material having a specific heat and a density larger than that of the heat insulating member. The volume of the heat storage means can be made smaller.

[0012] In the measuring apparatus having the configuration according to the fifth aspect, the result signal measured by the measuring unit outside the container is recorded in the measurement result recording unit inside the electrically insulated container. Also, the measurement result recording section is housed inside the heat insulating container body of the heat insulating container according to any one of claims 1 to 4, so that the above described claim 1, 2, 3, or 4 is provided.
The measurement result recording section is protected from high or low temperature by the action of the heat insulating container, and the heat insulating container can be reused more quickly than before, so that the measuring device can be reused more quickly than before.

【Example】

Example 1 Example 1 will be described with reference to FIGS. It is an object of the present embodiment to provide a heat insulating container in which the transfer of heat from the outer wall to the inner wall having a double structure is more favorably suppressed, in addition to the above-described object of the present invention. Another object is to provide a heat insulating container smaller than before. Furthermore, in a state where the temperature recording part which is the measurement result recording part and the temperature sensor which is the measurement part are arranged under high temperature and low temperature,
It is an object of the present invention to provide a temperature measurement device that can measure temperature and is smaller than a conventional temperature measurement device. The heat insulating container 1 of the first embodiment is shown in FIG.
As shown in FIG. 3, the temperature recording unit 3 has a double structure 2 which is a heat insulating container body having an access port 4 through which the temperature recording unit 3 can enter and exit, and a heat insulating plug 5 which allows the access port 4 to be opened and closed. The temperature measuring device 10 of the first embodiment using the heat insulating container 1 of the first embodiment is placed under a high temperature or a low temperature with the temperature recording unit 3 stored therein, and the temperature recording unit 3 is switched from the high temperature or the low temperature. For protection, the temperature sensor 3 is housed in the heat insulating container 1, and in a state where the access port 4 is closed by using the heat insulating plug 5, six sensor codes 6 connected to the temperature recorder 3 are provided. Is electrically connected to a temperature sensor 7 which is a temperature measuring portion outside the heat insulating container 1 through a slight gap between the heat insulating plug 5 and the inlet / outlet section 4, and this gap is substantially filled with the sensor code 6. You.

The double structure 2 is made of a stainless steel plate (thickness: 1 mm) having relatively low thermal conductivity among metals, and an outer wall located outside the heat insulating container 1 and an inner wall located inside the heat insulating container 1 are continuous. The space between the outer wall and the inner wall, that is, the inside of the double structure 2 is evacuated. The size of the heat insulating container 1 is only slightly larger than the temperature recording unit 3 so that the temperature recording unit 3 can be moved in and out. As shown in FIG. 2, the heat insulating plug 5 includes a heat insulating material outer layer 5A and a heat storage material layer 5B which are separate members.
The heat insulating material inner layer 5C is inserted into the heat-resistant fiber bag 5D in the above-described order, and the mouth of the bag 5D is closed. The heat insulating plug 5 corresponds to the heat insulating means in the claims, the heat insulating material outer layer 5A corresponds to the outer heat insulating member in the claims, the heat storage material layer 5B corresponds to the heat storage means, and the heat insulating material inner layer 5C corresponds to the inner heat insulating member. Each corresponds.

The heat insulating material outer layer 5A has a diameter of 90 mm and a thickness of 105 mm.
mm glass wall layer, and the heat storage material layer 5B has a diameter of 90 m.
m, stainless steel sheet with a thickness of 10 mm
C is a glass wool layer having a diameter of 90 mm and a thickness of 10 mm.
When closing the inlet / outlet part 4 with the heat insulating plug 5, the heat insulating outer layer 5A is located outside the inlet / outlet part 4, and the entire surface near the temperature recording part 3 is used as the heat insulating inner layer 5C. Thermal storage material layer 5
B is made of a copper plate coated with a rust-preventive paint, and has heat transfer members 8, 8 having semicircular ends at the ends thereof, which are attached to the corresponding two places with a heat-resistant adhesive. This heat transfer member 8,
Reference numeral 8 corresponds to a heat transfer means in the claims. Openings 5E, 5E are provided in the bag 5D in accordance with the position of the heat transfer member 8, and the heat transfer members 8, 8 are projected from the openings 5E, 5E to the outside of the bag, so that the heat insulating plug 5 In a state where the access port 4 is closed, the ends of the heat transfer members 8 are
Is brought into pressure contact with the inner wall. The fixing member 9 is made of heat-resistant resin, silicon, and the whole of the entrance / exit portion 4 is a heat insulating plug 5.
A flat portion covering the upper portion of the heat-resistant container 2 and a vertically continuous edge around the entire circumference of the flat portion.
The fixture 9 is fixed to the heat-resistant container 2 by being fitted to the double structure 2 in the vicinity, and detachment of the heat insulating plug 5 is prevented. In addition, as the temperature recording part 3, the product name is DATA COLLEC.
TOR (manufactured by Anritsu Keiki Co., Ltd.) was used. However, the thickness of the sensor code 6 was used instead of a thinner one.

When the temperature measuring device 10 of the first embodiment is used, the temperature recording section 3 is housed in the heat insulating container 1 and the heat insulating plug 5
In a state where the fixture 9 is attached to the heat insulating container 2 and the temperature sensor 7 is placed outside the heat insulating container 2, the heat insulating container 1 is arranged in a place where the temperature is measured, for example, in a baking oven. And the six temperature sensors 7 are arranged in different parts of the bread baking pan and / or different parts of the dough,
The temperature of each part is detected, a temperature detection signal is output, and the sensor code 6 transmits the temperature detection signal to the temperature recording unit 3 in the heat insulating container 1. The temperature recording unit 3 stores the transmitted temperature detection signal in a memory over time for each part. Even in a high-temperature baking oven, the double structure 2 is made of stainless steel having relatively low thermal conductivity among metals, the inside of which is evacuated, and the insulating plug 5 having an insulating effect. The temperature recording unit 3 is protected from high temperatures around the outside of the heat insulating container 1. Then, the outer wall of the double structure 2 is set to a high temperature, but the heat is not transmitted to the inner wall of the double structure 2 first.
It is suppressed by the fixture 9 made of a heat-resistant resin, and furthermore greatly suppressed by the heat storage material layer 5B and the heat transfer members 8, 8 as described later. The surface portion of the heat insulating outer layer 5A located outside the heat insulating container 1 has a high temperature which is substantially the same as the inside of the oven, but instead, heat outside the heat insulating container 1 is transmitted to the heat insulating material outer layer 5A by a certain amount or more. Will not be. This is because heat transfer occurs where there is a temperature difference. Then, the heat from the heat insulating material outer layer 5A is transmitted to the heat storing material layer 5B made of stainless steel having higher thermal conductivity than glass wool, and the heat is accumulated in the heat storing material layer 5B having a large heat capacity. Transfer of heat to the inner material layer 5C is suppressed. Further, since the copper heat transfer members 8, 8 having high thermal conductivity are in contact with the inner wall of the double structure 2, the heat transferred from the outer wall to the inner wall of the double structure 2 is transferred to the heat storage material layer by the heat transfer members 8, 8. 5B and stored. This suppresses the transfer of heat from the outer wall to the inner wall of the double structure 2, and suppresses the temperature rise of the temperature recording unit 3 due to the transfer of heat from the outer wall to the inner wall.

After the temperature is measured, the temperature measuring device 10 of the first embodiment is taken out of the high-temperature baking oven, the fixture 9 is removed from the heat-resistant container 2, the bag 5D is held, and the heat insulating plug 5 is connected to the heat-resistant container 2. From the entry / exit section 4. Next, the temperature recording unit 3 is taken out of the heat insulating container 1. The temperature recorded in the memory of the temperature recording unit 3 taken out is transferred to a host computer (personal computer) by a communication cable to read the data, and processing and management are performed. After this data transfer, the data is stored on a floppy disk on the PC side,
Be managed. In this way, the temperature measurement device 10 of the present embodiment can measure the change over time in the temperature of different parts in the high-temperature bread baking pan and / or different parts of the dough. Since the temperature of the heat insulating container 1 is maintained for a while after the measurement, if the temperature recording unit 3 is left in the heat insulating container 1 after the measurement, the temperature recording unit 3 is damaged by the heat of the heat insulating container 1. Although there is a danger, after the temperature measurement, the above-described problem does not occur because the temperature measuring device 10 of the present example can separate the temperature recording unit 3 from the insulated container 1 having a high temperature. Further, since the temperature recording unit 3 that is weak to temperature change is not stored in the double structure 2 after the temperature recording unit 3 is removed, the temperature can be rapidly cooled to room temperature. The time required to make 10 reusable may be reduced. Furthermore, the double structure 2 after removing the temperature recording unit 3 is hot only on the surface,
Since the heat capacity is smaller than that of the heat insulating material, the cooling of the temperature recording unit is quicker than in the case where the conventional temperature recording unit is housed in a heat-resistant container filled with the heat insulating material. Regarding the cooling of the heat insulating plug 5, as shown in FIG.
At 0, the amount of the heat insulating material used is smaller than when the temperature recording unit 34 is housed in a heat-resistant container filled with the heat insulating material D, so that the cooling is quicker.
Then, the heat insulating plug 5 of the present example 1 is separated from the bag by the heat insulating inner and outer layers 5C, 5C.
By taking out A and the heat storage material layer 5B, these three layers can be separated. The separated heat storage material layer 5B is a plate-shaped stainless steel, and has a higher thermal conductivity than a heat insulating material. It can be cooled rapidly to room temperature. Further, since it is stainless steel, it can be cooled using a liquid such as water, which is convenient and can reduce the time required for cooling. Further, the plate shape is also advantageous for rapid cooling. If the heat storage material layer 5B at room temperature is used, the temperature measuring device 10 of this embodiment can be reused without completely returning the inner and outer layers 5C and 5A of the heat insulating material to room temperature.
Further, when the temperature measuring device 10 of the present embodiment is to be reused more quickly, the high-temperature insulating plug 5 used for the previous temperature measurement may be used instead of the spare normal-temperature insulating plug 5.

According to the temperature measuring device 10 of the first embodiment,
As a means for insulating the temperature recording unit 3, the temperature recording unit 3 is housed in the stainless steel double structure 2 in which the inside is evacuated, and the insulating plug 5 is used, so that only the heat insulating material is used for heat insulation. As compared with the conventional case, the size of the heat insulating container 1 can be made smaller, so that the temperature measuring device 10 is smaller than the conventional case and is more convenient for use. Further, the heat storage material layer 5B is made of stainless steel and has higher specific heat and density than the heat insulating material, so that the heat storage material layer 5B has a larger heat capacity than the heat insulating material of the same volume. Therefore, there is an advantage that the volume of the heat storage material layer 5B can be made smaller as compared with the case where a material having only specific heat larger than that of the heat insulating material is used as the heat storage material layer 5B, and contributes to downsizing of the heat insulating container 1. In this example, since the heat insulating plug 1 is inserted into the heat insulating container 1, the inside of the heat insulating container 1 has a size such that the temperature recording unit 3 cannot move significantly. Is prevented from being damaged. Further, according to the temperature measuring device 10 of this embodiment, since the temperature recording unit 3 and the temperature sensor 7 are arranged in the baking oven, the temperature recording unit is arranged outside the oven and the sensor code is reduced. Unlike the case where the oven is arranged from outside the oven, the oven for measuring the temperature does not require a facility for disposing the sensor code 6 from inside the oven to the outside. Therefore, the temperature in any oven can be measured,
It is convenient. Then, as compared with the case where the temperature recording section is arranged outside the oven, the temperature can be measured at an arbitrary position in the oven without being largely influenced by the length of the sensor code 6. In this embodiment, since the stainless steel excellent in heat resistance, workability, rust resistance and strength is used as the material of the double structure 2, the heat insulating container 1 of the first embodiment is excellent in these points. In addition, since a glass wool having no problem of combustion is used as a heat insulating material, the fire resistance is excellent. In this embodiment, the heat transfer means in claim 2 is fixed to the heat storage material layer 5B. However, the heat transfer means may be fixed to the inner wall of the stainless steel double structure 2 which is the container main body and protruded into the container. The shape may be the hook shape of the hook and may be provided all around the inner wall, or may be provided at any number of places. Although the present embodiment has been described for the case where the measured room temperature is high, the measurement can be performed similarly when the measured room temperature is low.
Ambient temperature used is -40 ° C to +
It can be used optimally at 230 ° C. However, by changing the size of the heat insulating material inner and outer layers 5C, 5A and the heat storage material layer 5B, the temperature at which the temperature measuring device 10 can be used can be made higher or lower, and the usable time can be arbitrarily adjusted. can do. In addition, even when the sizes of the heat insulating material inner and outer layers 5C, 5A and the heat storage material layer 5B are changed, the temperature of the present example which can be used for the same time as compared with the case where heat insulation is performed by using only the conventional heat insulating material. The time required for reuse of the measuring device 10 is made shorter. In this embodiment, the case where the measurement target is temperature has been described. However, the measurement target is not limited to temperature, and various types of sensors, which are measurement units electrically connected to the measurement result recording unit stored in the heat insulating container 1, may be used. By using the sensor, various measurement objects under high or low temperature conditions can be measured by the measuring device of the present invention using the heat insulating container of the present invention.
