  Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described using the drawings.

(Whole structure of thermostat 1)
FIG. 1 is a front view showing a preferred embodiment of the thermostat of the present invention. FIG. 2 schematically shows an example of a ventilation route example for temperature control in the internal structure of the thermostat 1 shown in FIG. 1, a bottle B which is an example of a storage object stored in the thermostat, and a bottle thermometer 29 etc. FIG.

  The thermostatic bath 1 shown in FIG. 1 and FIG. 2 is a box-shaped storage which can control and manage the internal temperature precisely. For example, as illustrated in FIG. 2, the thermostatic chamber 1 can store a plurality of bottles B, which are objects to be stored, preferably in a state of maintaining a low temperature state, and is also referred to as a low temperature thermostatic chamber or a refrigerator. The thermostatic bath 1 temperature-controls the inside of the thermostatic bath 1 to store and manage it so that the bottle B containing a medicine or the like can be maintained at a low temperature of a predetermined temperature (for example, 4 ° C.).

  As shown in FIG. 1 and FIG. 2, the thermostatic chamber 1 includes a main body 2 and doors 3 and 3. The main body 2 and the doors 3 and 3 are made of metal, for example, made of SUS (stainless steel). The main body 2 is preferably a box-shaped container, and as shown in FIG. 1, the main body 2 has an upper surface 4, a lower surface 5, left and right side surfaces 6, 7, a back surface 8 and a front surface 9. There is.

  The main body 2 has an accommodating portion 20 inside. The front face 9 of the main body 2 is provided with a rectangular opening 10 for taking in and out the bottle B and the like. The main body 2 and the doors 3 and 3 maintain the sealing property and heat insulation to the outside. It includes an inner door (glass) to reduce temperature fluctuation when the door 3 is opened.

  As shown in FIG. 1, for example, the double-opening door 3 is attached to the main body 2 so as to be able to open and close using a hinge portion 11. The door 3 closes the opening 10 of the front surface 9 of the main body 2 in an openable / closable manner.

  As shown in FIG. 1, each door 3, 3 has, for example, a glass window 3 </ b> R having translucency so that the inside of the housing portion 20 of the main body 2 can be seen. As shown in FIG. 2, metal fingers 3 </ b> B and packing 3 </ b> C are disposed inside the door 3. The rectangular packing 3 </ b> C is disposed around the four sides of the opening 10 of the main body 2. When the door 3 closes the opening 10, the door 3 uses the packing 3C to hold the housing 20 in a sealed state.

  As shown in FIG. 1, the doors 3 and 3 include handles 3A and 3A, an authentication door lock 12 and an emergency door lock 13. The authenticated door lock 12 can lock the doors 3, 3 or, conversely, unlock the doors 3, 3 by, for example, bringing an authentication card closer to the authenticated user.

  The authentication door lock 12 can adopt, for example, an electromagnetic door lock that operates by receiving power supply from a commercial power source. As described above, since the door 3 is provided with the authentication door lock 12, when the thermostatic chamber 1 is in normal continuous operation, a person other than the authenticated user is the door 3, 3 I can not open it. Therefore, the bottle B stored in the storage unit 20 of the thermostatic bath 1 can not be taken out by anyone other than the authenticated user. As a result, when the thermostatic bath 1 continuously stores the bottle B at low temperature, security of the storage of the bottle B can be maintained.

  Further, the emergency door lock 13 shown in FIG. 1 is such that the door 3 is locked (locked) in an emergency, for example, at the time of a power failure, so that the door 3 is not opened. It is designed not to be taken out for preparation. As described above, when the thermostatic bath 1 can not receive power supply from outside due to a power failure, the bottle B stored in the storage unit 20 of the thermostatic bath 1 can be taken out by persons other than the authenticated user. Can not. Thereby, the thermostatic bath 1 can maintain security on storage of the bottle B at the time of a power failure. However, the emergency door lock 13 can be unlocked by a key owned by the device manager. In order to rescue the bottle B in the storage unit 20 from the temperature rise, after unlocking, it is transferred to another storage or storage box or the like.

  As shown in FIGS. 1 and 2, a rectangular parallelepiped housing portion 20 is provided inside the main body 2. As illustrated in FIG. 2, the storage unit 20 accommodates, for example, a plurality of bottles B filled with medicine, which is a storage object, and the bottles B have a predetermined temperature, for example, 2 ° C. to 8 ° C. It is preferable to store in the range and operate at 4 ° C. As shown in FIGS. 1 and 2, the housing portion 20 has an upper surface 20A, a lower surface 20B, left and right side surfaces 20C and 20D, and a back surface 20E.

  As illustrated in FIG. 2, at least one shelf plate 21 is detachably and horizontally disposed in the storage unit 20. The vertical position of the shelf board 21 can be changed. At least one bottle B is placed on the shelf board 21 and stored in a predetermined temperature range. Therefore, the bottle thermometer 29 can be set at the position where the temperature fluctuation is the largest, and can be stored so that the bottle B does not exceed the predetermined temperature range.

  As illustrated in FIGS. 2 and 3, in the case of using the RFID as the presence monitoring system, each bottle B includes an identification element 22 as an information transmitting unit for transmitting information on the bottle B. Is arranged. As shown in FIG. 3, a plurality of antennas 23A, 23B, 23C, and 23D are disposed on the inner surface of the housing portion 20 of the thermostatic bath 1.

  The RFID receives and reads the individual information of the bottle B stored in the identification element 22 by wireless communication, for example, by the antennas 23A, 23B, 23C, and 23D. The antennas 23A, 23B, 23C, and 23D are examples of an information receiving unit that receives individual information of the bottle B. That is, when the identification element 22 receives an inquiry wirelessly from, for example, any of the antennas, the identification element 22 may, for example, a serial number (lot number) of the bottle B, a bottle such as the type of medicine contained in the bottle B, etc. Information on B (drug) is wirelessly transmitted to the antenna described next.

These antennas are, for example, the serial number (lot number) as individual information of the bottle B transmitted from the identification element 22 of the bottle B described above, such as the bottle B (type of medicine contained in the bottle B, etc. Receive information on drugs).
The structure and the material of the shelf board 21 do not inhibit the transmission of the radio wave of the identification element 22.

  As a load monitoring system, besides RFID, there is also a monitoring system combining a weight and a camera monitor and a bar code. The information of the load monitoring system has a mechanism that can transmit data to the administrator together with the temperature data and the status of the device.

  As shown in FIG. 2, a temperature control air introduction path 30 is provided along the outside of the storage unit 20 in order to adjust the temperature in the storage unit 20. That is, the temperature control air introduction path 30 introduces the temperature control air CW into the storage section 20 through the temperature control air CW outside the upper surface 20A, the lower surface 20B, the left and right side surfaces 20C, 20D, and the back surface 20E of the storage section 20. .

  The temperature control air introduction path 30 shown in FIG. 2 has a temperature regulator 31 on the rear side of the back surface 20E. The temperature regulator 31 has a heat exchanger 32 and a heater 33. The heat exchanger 32 and the heater 33 of the temperature regulator 31 adjust the temperature in the tank of the storage unit 20.

  For example, as indicated by the arrows in FIG. 2, the low temperature conditioned air CW produced by the heat exchanger 32 passes from the path portion 30A of the back surface 20E to the path 30B of the top surface 20A, and from the opening 20H of the top surface 20A. , And is blown out into the storage unit 20. The temperature control air CW blown out into the housing portion 20 enters the path 30C from the opening 20J of the lower surface 20, passes through the path 30C, and returns to the heat exchanger 32 side. Thereby, the temperature regulator 31 can store the temperature of the bottle B at a predetermined temperature while maintaining the temperature in the storage unit 20 at the specified low temperature state. The range in which the bottle B can be stored is described on the shelf board 21 and stored and operated within the range.

  In addition, since the temperature regulator 31 is equipped with the heater 33 and the heat exchanger 32, temperature adjustment in the accommodating part 20 can be performed in the temperature range from 0 degreeC to about 60 degreeC, for example.

(Electric connection block of each element of thermostat 1)
Next, an example of electrical connection of each element of the thermostatic chamber 1 will be described with reference to FIG. FIG. 3 is a block diagram showing an example of electrical connection of each element of the thermostatic bath 1. As shown in FIG.

  The thermostatic chamber 1 is provided with each element illustrated in FIG. A load monitoring system 99 as a load monitoring unit shown in FIG. 3 monitors the load information DS of the bottle B in the inside of the storage unit 20 of the main body 2. The presence information DS is individual information on each bottle B contained in the containing portion 20, and for example, it enters in the serial number (lot number) of the bottle B in the containing portion 20, the bottle B Contains information such as the type of drug being For example, in the case where the load monitoring is performed by RFID with respect to the same system, the load monitoring system 99 shown in FIG. 3 includes the load monitoring control unit 40, the RFID antennas 23A to 23D, and the identification element 22 of each bottle B. And a presence monitoring system converter 50. The load monitoring control unit 40 is also electrically connected to the RFID antennas 23A to 23D.

  Further, the presence monitoring system converter 50 shown in FIG. 3 is electrically connected to the stock monitoring control unit 40 and the door lock 12 with authentication. The authentication door lock 12 can release the locked state of the door 3 and open the door 3 by bringing the authentication card, for example, close to the authentication card.

  The load monitoring system converter 50 is electrically connected to the external communication module 51 (also referred to as an external communication module). The load monitoring control unit 40 outputs the above-described load information DS to the load monitoring system converter 50. The authentication door lock 12 outputs locking / unlocking information RR indicating whether the authentication door lock 12 is in the locked state or the unlocked state to the presence monitoring system converter 50.

  As a result, the load information DS and the locking and unlocking information RR are integrated in the load system converter 50 and output to the external communication module 51 as consolidated information G. The external communication module 51 transmits the aggregated information G to the outside of the main body 2 wirelessly or by wire.

  On the other hand, a control thermometer 60 shown in FIG. 3 can use, for example, a thermocouple. As illustrated in FIG. 3, the control thermometer 60 is disposed at an arbitrary position in the housing portion 20, for example, at a position on the upper side on the back side of the housing portion 20. As shown in FIG. 3, the control thermometer 60 is electrically connected to the temperature regulator 31 and the temperature monitor 62.

  The temperature regulator 31 is electrically connected to the abnormality alarm unit 61. The temperature regulator 31 performs temperature adjustment so that the inside of the storage unit 20 (in the tank) can be continuously maintained at a constant temperature and a low temperature based on the measured temperature information M in the storage unit 20 from the control thermometer 60. Thus, the temperature of each bottle B is maintained at a predetermined temperature, preferably 4 ° C.

  The plurality of bottle thermometers 29 of FIG. 3 are placed at arbitrary positions on the shelf board 21 as illustrated in FIG. 3. Each bottle thermometer 29 measures the temperature of the bottle B as a dummy of the bottle B instead of directly measuring the temperature of the bottle B which is the storage object, and the temperature of the bottle temperature information BT measured by the bottle thermometer 29 is the temperature of the bottle B It is regarded as The bottle thermometer 29 is an example of a storage object thermometer.

  As illustrated in FIG. 2, the bottle thermometer 29 has a dummy bottle DB. The size and material of the dummy bottle DB can be, for example, the same as those of the bottle B. In the dummy bottle DB, for example, non-toxic glycol is contained as a bottle internal liquid 29W, and the temperature sensor 29P is configured to measure the temperature of this glycol.

  The bottle internal liquid 29W is a dummy drug corresponding to the drug contained in the bottle B. Thus, the bottle thermometer 29 can monitor the temperature of the medicine of the bottle B in the storage unit 20 instead of directly measuring the temperature of the bottle B in the storage unit 20.

  The bottle thermometer 29 W is easily influenced by the external atmosphere in the main body 2, and it is desirable that the bottle thermometer 29 W be installed at a position where the liquid temperature fluctuation is the largest. As exemplified in FIG. 2, the plurality of bottle thermometers 29 are, for example, a position on the front side near the door 3 which is a position where temperature change is likely to occur when the door 3 is opened, and a depth of the storage unit 20 away from the door 3 It is preferable to arrange in the side position.

  The bottle thermometer 29 of FIG. 2 is disposed separately from the bottle B on the shelf board 21 in the storage unit 20 to monitor the temperature of the bottle B. As shown in FIG. 3, the temperature of the bottle temperature information BT detected by the bottle thermometer 29 is treated as the temperature of the bottle B which is a work. That is, since the temperature of the medicine in the bottle B can not be measured directly, the temperature of the bottle temperature information BT measured by the bottle thermometer 29 is treated as the temperature of the temperature information of the bottle B. The temperature of the bottle temperature information BT is digitally displayed by the bottle temperature display unit 64 of the temperature monitor 62.

  FIG. 4 shows a temperature monitor 62. The temperature monitor 62 is disposed on the upper surface 4 of the main body 2 as also shown in FIG. As shown in FIG. 4, the temperature monitor 62 has a control temperature display unit 63 and a bottle temperature display unit 64.

  The control temperature display unit 63 shown in FIG. 3 digitally displays the controlled temperature in the storage unit 20 based on the measurement temperature information M from the control thermometer 60. The bottle temperature display unit 64 digitally displays the temperature of each bottle B based on the bottle temperature information BT from the bottle thermometer 29.

  For example, as shown in FIG. 4, the abnormality alarm unit 61 shown in FIG. 3 is disposed in the temperature monitor 62. The abnormality alarm unit 61 has, for example, the abnormality alarm lights 61A and 61B shown in FIG. 4 and an abnormality alarm sound generation unit 61C. The abnormality alarm lamp 61A lights up when the temperature of the bottle B exceeds a predetermined temperature (for example, 4 ° C.), for example, 6 ° C. of the alarm set value, and warns of an abnormal rise of the temperature of the bottle B. The abnormality alarm lamp 61B also lights up when the temperature of the bottle B falls below a predetermined temperature, for example, 2 ° C., and warns of an abnormal drop of the temperature of the bottle B.

  Similarly, the abnormal alarm sound generation unit 61C generates an alarm sound when the temperature of the bottle B exceeds a predetermined temperature (for example, 4 ° C.), for example, an alarm set value of 6 ° C. The abnormal alarm sound generation unit 61C also generates an alarm sound when the temperature of the bottle B falls below a predetermined temperature, for example, 2 ° C.

  The UPS power supply (uninterruptible power supply) 70 shown in FIG. 3 supplies power to the temperature monitor 62 and the external communication unit 51 when the commercial power supply supplying power to the main body 2 fails. The door (door) release alarm unit 71 generates an alarm sound when the door 3 is opened beyond a preset time. The door release alarm unit 71 is electrically connected to the temperature regulator 31.

  When the emergency door lock 13 shown in FIG. 3 releases the electromagnetic lock of the authenticated door lock 12 when the commercial power supply fails, the emergency door lock 13 forcibly locks the doors 3 of FIG. Make sure that door 3 does not open.

  Thus, at the time of a power failure, by preventing the doors 3 and 3 from opening, the bottle B in the storage unit 20 is not taken out carelessly. For this reason, when the thermostatic bath 1 does not receive power supply from the outside by a power failure, since the person other than the authenticated user can not open the door 3, security in storage of the bottle B can be maintained.

  Also, no person other than the authorized user can open the door 3. Therefore, if the temperature of the medicine in the bottle B exceeds, for example, 8 ° C. by raising the temperature in the storage unit 20, this medicine can not be used. You can prevent accidental removal and use.

  Thus, the authenticated door lock 12 shown in FIG. 3 allows only an authorized user to unlock the door 3, 3 in order to restrict the door 3 from being opened carelessly. For this reason, since the person other than the authenticated user can not open the doors 3 and 3 while the constant temperature bath 1 is performing the normal low temperature continuous operation, the security of the storage of the bottle B can be maintained.

  In addition, the emergency door lock 13 locks the door B in the housing portion 20 carelessly by, for example, locking the door 3 in an emergency state, for example, in the event of a power failure so that the door 3 does not open. It is designed not to be issued. For this reason, when the thermostat 1 does not receive power supply from the outside by a power failure, since the person other than the authorized user can not open the door 3, 3, maintenance of the security on storage of the bottle B is carried out. it can.

  The storage converter 80 shown in FIG. 3 aggregates the temperature and state in the storage unit 20, information such as the bottle temperature information BT, and abnormality alarms of these information, and outputs them as the aggregation information P to the external communication unit 51. . The external communication unit 51 outputs the aggregated information P to the outside of the main body 2 wirelessly or by wire.

(Example of temperature control of bottle B in constant temperature bath 1)
Next, with reference to FIG. 5, an example of temperature control of the bottle B stored in the storage unit 20 of the thermostatic bath 1 of FIG. 2 will be described. FIG. 5 shows an example of temperature control of the bottle B stored in the storage unit 20 of the thermostatic chamber 1.

  In FIG. 5, the vertical axis indicates the temperature T (° C.), and the horizontal axis indicates the time (t). A preferred temperature setting example is shown on the vertical axis of FIG. For example, the bottle temperature TP is 4 ° C., the lower limit T2 of the bottle temperature is 2 ° C., and the upper limit T1 of the bottle temperature is 8 ° C. The alarm set value TS for warning of the bottle temperature is, for example, 6 ° C., which is a temperature lower than 8 ° C. The bottle temperature TP is a temperature of the bottle temperature information BT obtained by the bottle thermometer 29 shown in FIG. 5 described above.

  FIG. 5 shows the curves TT and TT1 of the bottle temperature TP and the curve TR of the temperature of the storage portion 20 (in the tank). When the door 3 of FIG. 2 is opened at time t0 with the bottle temperature TP of the bottle B disposed in the storage unit 20 shown in FIG. 5 maintained at 4 ° C., the curve TT of the bottle temperature TP and the tank The internal temperature curve TR starts to rise together at 4 ° C.

  In FIG. 5, since the door 3 is opened from time t0 to time tC, the curve TR of the temperature in the tank further rises above the upper limit value T1 (8 ° C.), so that the curve TT of the bottle temperature TP There is a risk that the temperature exceeds 4 ° C. of the predetermined temperature and 6 ° C. of the alarm set value TS.

  As described above, when the bottle temperature TP exceeds a predetermined alarm set value TS (for example, 6 ° C.), the abnormality alarm sound generation unit 61C shown in FIG. 3 generates an alarm sound (alarm). The abnormal alarm sound generation unit 61C generates an alarm sound, whereby the user who has received the alarm can close the doors 3 and 3 immediately. Thereby, even if the door 3 is opened, the door 3 can be closed so that the medicine in the bottle B does not exceed the upper limit value T1.

  The value of time Δt from time t0 to time tC is a variable, and varies depending on, for example, the size and material of the bottle, the type and amount of medicine, and the like.

  In FIG. 5, when the door 3 is further closed at time tD, the curve TR of the temperature in the tank lowers and the curve TR of the temperature in the tank maintains the predetermined temperature 4 ° C. again, so the curve TT of the bottle temperature has the upper limit T1. It does not exceed (8 ° C) and gradually falls again to 4 ° C.

  For example, at time tD, the curve TR of the in-tank temperature is 4 ° C. Assuming that the curve TT of the bottle temperature TP is lowered to, for example, about 5 ° C., if the user opens the door 3 again at time tD, the curve TT of the bottle temperature TP is a curve of the bottle temperature TP As shown in TT1, it rises again.

  Then, since the bottle temperature TP exceeds the alarm set value TS at time tE, the abnormal alarm sound generation unit 61C shown in FIG. 3 generates an alarm sound (alarm) again. The abnormal alarm sound generation unit 61C generates an alarm sound, whereby the user who receives the alarm can immediately close the doors 3 and 3 at time tE. Thereby, even if the door 3 is opened again, the bottle B can be stored at 4 ° C. at the predetermined temperature in the housing portion 20 so that the medicine in the bottle B does not exceed the upper limit value T1. .

  In the storage unit 20, as shown in FIG. 3, two temperatures, ie, the temperature of the bottle B obtained from the bottle thermometer 29, and the inside of the storage unit 20 obtained by the control thermometer 60 in the storage unit 20. To get the ambient temperature of As a result, the temperature rise of the bottle B can be suppressed, so that the temperature of the bottle B can be controlled within the specified range in the storage unit 20.

(Operation of thermostat 1)
Next, an operation example of the thermostatic chamber 1 will be described with reference to FIGS. 6 to 8. FIG. 6 is a flow showing a normal operation example of the thermostatic chamber 1, and FIG. 7 is a flow in the case where the door 3 is opened and the bottle B (drug) is taken out from the inside of the storage unit 20. FIG. 8 is a flow when the commercial power supply fails.

(1) Normal Driving Operation Example First, a normal driving operation example of the thermostat 1 will be described with reference to FIG.

  In step S1 shown in FIG. 6, the door 3 shown in FIG. 2 closes the opening 4 and is in a locked (locked) state, and the housing portion 20 is sealed.

  At step S2 in FIG. 6, the control thermometer 60 shown in FIG. 3 detects the temperature in the storage unit 20 to manage the temperature in the storage unit 20 (inside storage), and the measured temperature information M is measured. It is output to the regulator 31. The temperature regulator 31 holds the inside of the storage unit 20 (in the tank) at a specified temperature based on the measured temperature information M in the storage unit 20 from the control thermometer 60.

  Thus, the thermostatic bath 1 shown in FIG. 2 has the bottle B containing the medicine contained in the storage unit 20 at a predetermined predetermined temperature (for example, the bottle temperature TP = 4.degree. C. shown in FIG. 5). Continuous operation for low temperature storage under low temperature conditions.

  In step S3 of FIG. 6, the status of low-temperature continuous operation of the thermostatic chamber 1, that is, consolidated information G including the presence information DS and the locking / unlocking information RR shown in FIG. , And aggregated information P in which abnormal alarms of the information are aggregated are output to the external communication unit 51. The external communication unit 51 transmits the aggregated information G, P to the outside by wireless or wired communication.

  In step S4 of FIG. 6, during low-temperature continuous operation of the thermostatic chamber 1, the control thermometer 60 monitors the environmental temperature in the storage unit 20 and controls the operation of the temperature regulator 31 to control the storage unit. Since the inside of the chamber 20 is in a low temperature state, the bottle temperature TP (storage temperature of medicine) is maintained at a predetermined temperature, for example, 4 ° C.

  In step S5 of FIG. 6, the temperature monitor 62 is obtained by the bottle temperature information BT from the bottle thermometer 29, and the temperature of the medicine of the bottle B in FIG. It is confirmed that the predetermined temperature (4 ° C.) is an arbitrary temperature not exceeding the temperature (8 ° C.) of the upper limit value T1 shown.

  In step S6 of FIG. 6, for example, when the user opens the doors 3 and 3, when the temperature of the bottle B shown in FIG. 2 exceeds the alarm set value TS shown in FIG. 5, the process proceeds to step S7.

  In step S7, the abnormality alarm lamp 61A of the abnormality alarm unit 61 shown in FIG. 3 lights up at a temperature at which the bottle temperature TP of the bottle B shown in FIG. 5 exceeds the alarm set value TP, for example 6 ° C. At the same time, the abnormal alarm sound generation unit 61C generates an alarm sound.

  As a result, the user who receives the alarm immediately closes the doors 3 and 3 so that the temperature of the storage unit 20 does not rise any more, and the bottle temperature TP of the bottle B does not exceed the alarm set value TS. The low temperature state in the housing portion 20 can be maintained. Therefore, it is possible to reliably prevent the medicine in the bottle B from being unusable due to the temperature rise of the bottle temperature TP, and wasteful disposal of the medicine can be eliminated.

  As described above, the temperature in the storage section 20 (in the storage) of the thermostatic chamber 1, which is a storage for the medicine, is monitored by the control thermometer 60 shown in FIG. There is. Moreover, the storage temperature of the medicine in each bottle B stored in the storage unit 20 is managed by the bottle temperature information BT obtained from the bottle thermometer 29.

  Thus, the thermostatic chamber 1 has a total of two temperatures: a temperature control system in the storage unit 20 by the control thermometer 60 and a temperature control system of the temperature (drug temperature) of the bottle temperature information BT by the bottle thermometer 29 Equipped with a management system.

  Therefore, while the thermostatic chamber 1 is continuously operated at a low temperature, the temperature of the medicine in the bottle B, which is the storage object in the thermostatic chamber 1, should be precisely managed to be a predetermined temperature (for example, 4 ° C.) Can. Since the temperature of the bottle B obtained from the bottle thermometer 29 and the environmental temperature in the storage unit 20 obtained by the control thermometer 60 in the storage unit 20 are obtained, double temperature management is performed to obtain the bottle B Since the temperature rise can be suppressed, the temperature of the bottle B can be controlled within the specified range in the storage unit 20.

(2) Operation Operation Example for Removing a Bottle (Drug) Next, referring to FIG. 7, an operation operation example for a certified user to remove the bottle B (drug) will be described.

  In step S11 of FIG. 7, the authenticated user inputs an authentication number, for example, by bringing the card storing the authentication number closer to the recognition device of the door 3. Thereby, since the authentication door lock 12 shown in FIGS. 1 and 7 can release the door lock of the door 3, the user opens the door 3, 3 and opens the bottle B in the storage unit 20. It is possible to access and take out and replace the bottle B.

  In step S13 of FIG. 7, when the release time of the door 3 shown in FIG. 2 reaches a predetermined set time, for example, time .DELTA.t from time t0 to time tC shown in FIG. The door (door) release alarm unit 71 of FIG. 2 can warn the user to close the inside of the storage unit 20 by immediately closing the door 3 by generating an alarm sound.

  Then, in step S15 of FIG. 7, when the user who receives the alarm closes the door 3, the door 3 is closed within a predetermined set time. Since it is locked by the authenticated door lock 12, no one other than the authorized user can open it carelessly.

  On the other hand, when the bottle temperature TP shown in FIG. 5 exceeds the alarm set value TS (for example, 6 ° C.) in step S16 of FIG. 7, the bottle temperature TP abnormally rises in step S17. The abnormality alarm lamp 61A of the unit 61 is turned on, and the abnormality alarm sound generator 61C generates an alarm sound.

  For this reason, the user who receives the alarm can confirm that the bottle temperature TP is abnormally rising with light and sound. It is possible to prevent the temperature rise. As a result, the temperature rise of the bottle B can surely prevent the medicine in the bottle B from becoming unusable, and wasteful disposal of the medicine can be eliminated.

  When the bottle temperature TP shown in FIG. 5 does not exceed the temperature of the alarm set value TS in step S16 of FIG. 7, the process proceeds to step S15.

  In step S18 in FIG. 7, when the door 3 is closed within the set time, the temperature regulator 31 in FIG. 3 keeps the inside of the storage unit 20 (inside the container) constant at the stage when the authentication door lock 12 locks the door 3. Since the bottle B is cooled to the bottle temperature TP (for example, 4 ° C.), which is a predetermined temperature, as illustrated in FIG. 5, the cooling state of the bottle B is maintained. That is, the inside of the storage unit 20 (inside storage) is continuously held at a constant designated temperature. In step S19, the external communication unit 51 transmits the aggregation information G and P shown in FIG. 3 to the outside of the main body 2 by wireless or wired communication.

  Note that when the bottle temperature TP illustrated in FIG. 5 falls below the alarm set value TS, the abnormality alarm lamp 61A of the abnormality alarm unit 61 in FIG. 3 is extinguished, and the alarm of the abnormality alarm sound generation unit 61C is canceled. The alarm set value TS is cooled and stored at 4 ° C., which is a predetermined temperature, so that the bottle temperature TP in FIG. 5 does not exceed the upper limit value T1 (for example, 8 ° C.) after closing the door 3.

(3) Operation Operation Example for Removing a Bottle (Drug) Next, with reference to FIG. 8, an operation operation example when the commercial power supply to which the thermostatic bath 1 is connected is interrupted will be described.

  In step S21 of FIG. 8, the thermostatic bath 1 shown in FIG. 1 operates continuously as a low temperature thermostatic bath, and as shown in FIG. 2, the bottle B containing the medicine contained in the container 20 is It is stored at a low temperature at a predetermined temperature (for example, a low temperature shown in FIG. 2 which is a bottle temperature TP = 4 ° C.).

  If the commercial power supply fails in step S22 of FIG. 8, the power supply to the authenticated door lock 12 shown in FIG. 1 is lost in step S23, and thus the locking of the door 3 is released. Therefore, when the emergency door lock 13 receives power supply from the UPS power supply 70, the emergency door lock 13 locks the door 3, instead of the authenticated door lock 12.

  As a result, even if a power failure occurs, no one other than the authenticated user can open the door 3, so that the bottle B in the storage unit 20 can not be taken out and can be stored reliably. That is, since the person other than the authenticated user can not open the door 3 when the thermostat 1 does not receive the power supply from the outside due to the power failure, the security of the bottle B can be maintained.

  If the commercial power supply fails at step S24 in FIG. 8, the temperature monitor 62 shown in FIG. 3 that monitors the temperature in the storage unit 20 (inside storage) and the external communication unit 50 are supplied with power from the UPS power supply 70. Receive Therefore, in step S25, the control temperature display unit 63 of the temperature monitor 62 detects a temperature abnormality in the storage unit 20 (inside the storage) even if the commercial power supply fails and can not receive power supply from the outside. Bottle temperature anomalies can be displayed.

  The bottle temperature display unit 64 of the temperature monitor 62 can display an abnormal temperature state in which the temperature of the alarm set value TS of the bottle B shown in FIG. 5 is exceeded. Even in the event of a power failure, the external communication unit 51 of FIG. 3 communicates with the outside of the main body 2 wirelessly or by wire the temperature abnormality in the storage unit 20 (inside storage) and the temperature abnormality in the bottle B. Can.

  At the time of a power failure in step S26 of FIG. 8, the authenticated user can manually release the lock state of the door 3, 3 of FIG. 1 by the emergency door lock 13 of FIG. For this reason, the user takes out each bottle B in the storage unit 20 even during a power failure, and takes out each bottle B taken out into a device holding a low temperature state such as another thermostatic chamber, It can be transferred as an emergency evacuation procedure.

  Thereby, it can be reliably prevented that the medicine in the bottle B becomes unusable due to the temperature rise of the bottle temperature, and wasteful disposal of the medicine can be eliminated.

  The constant temperature bath 1 is a low temperature storage which can store the bottle B at a low temperature. The temperature of the bottle B is determined by the temperature of the bottle B obtained by the bottle thermometer and the temperature in the container 20 obtained by the control thermometer 60 disposed in the container 20. While being able to perform double temperature control, inventory management of the bottle B accommodated in the accommodating part 20 can be performed. As a result, the actual temperature of the bottle B, which is an article actually stored, and the ambient temperature management for controlling the temperature in the storage unit 20 required for the actual temperature within the management temperature zone can be linked, and the storage unit It is possible to prevent the actual temperature of the bottle B from deviating without delaying the adjustment of the atmosphere temperature in 20.

  As described above, the thermostatic bath 1 according to the embodiment of the present invention includes the main body 2 having the storage portion 20 for storing, for example, the bottle B as an object to be stored in a temperature-adjusted state, and the storage portion of the main body 2 A door 3 for opening and closing 20, a bottle thermometer 29 as a storage object thermometer for detecting temperature information BT of the bottle B in the storage unit 20, and a control thermometer 60 for detecting the temperature in the storage unit 20; Information disposed in the bottle B, for example, the identification element 22 as an information transmitting unit for transmitting information on the bottle B in the storage unit 20 and information disposed in the main body 2 to receive information on the bottle B from the identification element 22 Based on the temperature in the storage unit 20 detected by the control thermometer 60 in order to maintain the temperature of the bottle B at a predetermined temperature (for example, 4 ° C.) disposed in the main body 2 with the antennas 23A to 23D as receiving units. The Comprising a temperature adjuster 31 for adjusting the temperature of the housing portion 20.

  Thereby, the bottle thermometer 29 can detect the temperature of the bottle B, and the temperature regulator 31 determines the temperature of the bottle B as the storage object based on the temperature in the storage unit 20 detected by the control thermometer 60. The temperature in the storage unit 20 is adjusted to keep the temperature at a predetermined temperature. For this reason, when storing the bottle B which is an object to be stored, double temperature management can be performed using the temperature of the bottle B which is an object to be stored and the ambient temperature in the storage unit 20. It is possible to perform precise temperature control of objects to be stored under strict control. For example, since the temperature in the storage unit 20 is adjusted so as to maintain the temperature of the bottle B at a predetermined temperature (for example, 4 ° C.), when storing the bottle B, the bottle B is precisely controlled based on strict management. Temperature control can be performed.

  The thermostatic chamber 1 monitors a load monitoring unit 99 that monitors load information on the bottle B in the storage unit 20, temperature information BT of the bottle B, and load information DS from the load monitoring unit. The external communication unit 51 transmits to the outside of the

  Thus, the external communication unit 51 can transmit the temperature information BT of the bottle B and the load information DS from the load monitoring unit 99 to the outside of the main body 2, so that the storage status of the bottle B It can be confirmed at a position away from 2.

  The object to be stored is a bottle B containing a medicine, and the bottle thermometer 29 has a bottle DB containing an internal liquid, and a sensor 29P for measuring the temperature of the internal liquid 29W.

  Thus, instead of directly measuring the temperature of the bottle B, the bottle thermometer 29 measures the dummy temperature and considers it as the temperature of the bottle B. The temperature of the bottle B can be obtained accurately and easily.

  The main body 2 controls the temperature in the storage unit 20 by controlling the temperature in the storage unit 20 by detecting the temperature in the storage unit 20, and the temperature in the storage unit 20 and the bottle thermometer A temperature monitor 62 for displaying temperature information BT of the bottle B from 29 and an emergency power supply 70 for supplying power to the external communication unit 51 and the temperature monitor 62 when the power supply to the main body 2 is stopped.

  As a result, the control thermometer 60 can accurately adjust the temperature in the storage unit 20 by the temperature regulator 31, and the external communication unit 51 and temperature monitor can be used even during a power failure where the main body 2 does not supply power. 62 can be operated by supplying power from a UPS power source which is an emergency power source. Therefore, the temperature monitor 62 can display the temperature abnormality in the storage unit 20, and the external communication unit 51 can notify the outside of the main body 2 of the temperature abnormality state in the storage unit 20 at the time of the power failure.

  The thermostatic chamber 1 is a door lock 12 for locking the door 3 and an emergency door for locking the door 3 instead of the door lock 12 when the power supply to the main body 2 is stopped and the door lock 12 can not lock the door 3. It has a lock 13.

  As a result, the emergency door lock 13 locks the door 3 even if the power supply to the main body 2 is stopped and the power failure state occurs, so that the bottle B in the storage unit 20 is not taken out carelessly, Security of the storage of the bottle B can be maintained.

  In the thermostatic bath 1, when the door 3 is released, when the temperature of the bottle B exceeds an alarm set value TS of a predetermined temperature, the thermostat 1 has an abnormality alarm unit 61 that issues an alarm of temperature abnormality increase.

  As a result, when the temperature of the bottle B exceeds the alarm setting value TS of the predetermined temperature, the abnormality alarm unit 61 issues an alarm of temperature rise, so the user immediately closes the door 3 and the temperature of the bottle B It can prevent the rise. Therefore, it can be reliably prevented that the substance such as the medicine in the bottle B becomes unusable due to the temperature rise of the bottle B, and wasteful disposal of the substance such as the medicine can be eliminated.

  In the thermostatic chamber 1 described above, data of the control temperature of the temperature regulator 31 in the storage unit 20 is also preferably transmitted to the outside by the external communication unit 51. As a result, by outputting the control temperature to the outside, it is possible to manage the indication of the failure of the thermostatic bath 1 from the continuous data. Based on the temperature stability when the door 3 is not opened or closed at night and the temperature recovery time when the door 3 is opened, the conditions of the thermostatic chamber 1 as an apparatus can be grasped quickly, and the thermostatic chamber 1 is free of problems. One diagnostic response can be performed.

  In the thermostatic bath 1 of the above-described embodiment, for example, as an object to be stored, a medicine which needs to be stored at a low temperature of a predetermined temperature is exemplified, but the invention is not limited thereto. It may be

  For example, the identification element 22 is disposed in each bottle B as an information transmission unit for transmitting information, but the information transmission unit may be of another type. The number, arrangement position, and arrangement attitude of the antennas as the information receiving unit can be set arbitrarily.

  The number of the shelf boards 21 and the like are not limited to the example shown in FIG. The chemicals and the like which require precise temperature control are not limited to, for example, glass bottle-like containers, and may be containers of other shapes.
