- step S20 the heater output is set to 0, and the process proceeds to step S22 to perform the nebulizer removal process.
- step 24 the supply of power to the outlet C is cut off and the process ends.
- FIG. 15 shows a detailed flow that is repeated at a constant cycle (for example, 10 seconds) in the heater control in step S18.
- step S30 the heater state is monitored to check for temperature abnormality, heater disconnection, and non-installation of the nebulizer adapter XB1 (using a mechanical switch not shown). If the heater state is abnormal, the heater output is updated to 0 in step S32, and the process returns to step S30. On the other hand, if the heater is normal in step S30, the process proceeds to step S34 to perform an initial heating process.
- the initial heating process is performed only when the output of the plate heaters 62a and 62b is switched from OFF to ON (the process is performed only when the initial flag is ON).
- the output of the plate heaters 62a and 62b is increased stepwise, and then the plate heaters 62a and 62b are set to the first output and wait for a certain period of time to wait for the temperature to stabilize.
- the heater temperature (first heater temperature)
- the temperature of the mixed gas (first gas temperature) and the ambient temperature (first ambient temperature) are measured.
- the plate heaters 62a and 62b are set to the second output and wait again to wait for the temperature to stabilize, the heater temperature (second heater temperature), the temperature of the mixed gas (second gas temperature), and the ambient temperature (second Ambient temperature) is measured. From the difference between the various temperatures of the first output and the various temperatures of the second output, the temperature change amount of the mixed gas per unit output change amount (or the output change amount required for the unit gas temperature change amount) is the first control reference value. Further, the temperature change amount of the heater per unit output change amount (or the output change amount with respect to the unit heater temperature change amount) is calculated as the second control reference value, and then the initial flag is turned OFF. Thereafter, using the first control reference value, the plate heaters 62a and 62b are controlled such that the temperature of the mixed gas discharged from the actual nebulizer XA1 becomes the set temperature.
- preset fixed values may be used.
- a plate heater when the temperature of the mixed gas is stabilized at the first temperature target value by feedback control or the like.
- the output values of 62a and 62b may be the first output

- the first and second control reference values can be calculated by detecting stable values under at least two conditions where the temperature of the mixed gas is different from each other.
- step S36 the mixed gas temperature is checked in step S36.
- the heater temperature and heater output are recorded in the memory R. The heater temperature and the heater output are used as initial values for controlling a water shortage determination mode, which will be described later, and when returning from a water shortage state (that is, when returning with the initial flag set to OFF).
- the process proceeds to step S38 to check the heater temperature stability.
- the heater temperature stability confirmation is performed by evaluating how much the heater temperature of the plate heaters 62a and 62b changes in a predetermined time. For example, the heater temperature is measured in increments of 1 minute, and if the amount of change between the immediately preceding temperature and the current temperature is within a predetermined threshold, it is determined to be stable, and if it exceeds a predetermined threshold, it is determined to be unstable.
- a value obtained by further differentiating the change amount can be used as a determination value, or a moving average value can be used as a determination value.
- the process proceeds to the heater output change process in step S40, and the outputs of the plate heaters 62a and 62b are changed so as to eliminate the difference between the temperature of the mixed gas and the set temperature.
- This output change value uses the already calculated first control reference value to calculate the amount of output change necessary to eliminate the temperature difference between the gas mixture temperature and the set temperature, and adds this to the current output. Or, it is determined by subtraction.
- the calculation result exceeds the preset heater temperature upper limit value and / or the heater output upper limit value, the maximum output in a range not exceeding the upper limit value is determined.
- the output change value is the same as the current output value.
- step S42 the process waits for a certain time (for example, 20 seconds) until the temperature of the plate heaters 62a and 62b after the change of output and the temperature of the mixed gas change, and then the process proceeds to step S43. Also check the stability of the mixed gas temperature. When both the heater temperature and the mixed gas temperature are stable, the process proceeds to step S60, and the temperature change amount of the mixed gas before and after the output change and the temperature change amount of the heater are used as described above.
- the first and second control reference values are updated, stored in the memory R together with the latest gas mixture temperature and heater temperature, and the process returns to step S30. In this way, it is possible to always maintain an optimal control reference value against changes in the external environment (temperature and humidity changes) and flow rate changes.
- step S43 when it is determined in step S43 that either one of the heater temperature and the mixed gas temperature is unstable, the process proceeds to step S62 to check the excess response. Specifically, when the output of the plate heaters 62a and 62b is increased, the temperature of the mixed gas exceeds a preset temperature (for example, +0.5 degrees) or the plate heaters 62a and 62b When the output of is decreased, it is confirmed whether the temperature of the mixed gas is lower than the set temperature by a predetermined amount (for example, ⁇ 0.5 degrees).

- step S46 the process waits for a certain time (for example, several minutes) until the temperature of the plate heaters 62a and 62b after the change of output is stabilized, and then determines whether the water runs out in step S48.
- the water outage determination in step S48 is performed by the number of continuous number counters in step S44. In this embodiment, if the continuous number counter is within six times, it is determined that water still exists, and step S38 is performed. Return to, and check the heater temperature stability. If the heater temperature is not stable, the heater temperature stability control process in step S44 is repeated.
- step S50 If the heater temperature does not converge to the stabilization target value in the heater temperature stability confirmation in step S38 even after the heater temperature stability control in step S44 is repeated six times, the continuous number counter in step S48 reaches seven times. As a result, it is determined that an abnormal change has occurred in the external environment of the heater, that is, water has run out, and water out warning processing is performed in step S50. In the water out warning process, the outputs of the plate heaters 62a and 62b are updated to 0, the water out display part 75 of the operation panel 70 is turned on, and an alarm is issued by the buzzer 93 to appeal to the user's hearing or vision. The process returns to step S14 of the basic control flow and waits.
- both the determination of the amount of deviation of the temperature of the mixed gas from the target value (set temperature) and the determination of the uneasy low level of the heater temperature are evaluated, and the mixed gas temperature deviates from the target value.
- the heater temperature is stable, it is determined that the set temperature has changed or the flow rate of the mixed gas has changed, and the heater output is controlled so that the mixed gas temperature follows the target value.
- the heater temperature is unstable and the heater output is controlled with the heater temperature itself as a target value, the heater temperature is still unstable, and water outage determination is performed.

- the output of 62b is detected. When the output is large, it is determined that the specific heat or the amount of heat of the object is large, and when the output of the plate heaters 62a and 62b is small, it is determined that the specific heat or the amount of heat of the object is small.
- the specific heat or heat capacity of the object is the smallest when (1) the nebulizer adapter XA1 itself is not installed, and (2) the nebulizer adapter XA1 is installed but the liquid 2 of the liquid receiving portion 15a is empty. (3) Although the liquid 2 is accumulated in the liquid receiving portion 15a, the aerosol is ejected from the ejection port 16a because the oxygen gas is not ejected from the orifice 12a. The case where there is no is larger than (2), and (4) the case where the liquid 2 is accumulated in the liquid receiving portion 15a and the aerosol is ejected from the ejection port 16a is the largest. Therefore, various states can be determined by detecting the difference in specific heat between (1) to (4).

If various determination thresholds are used, the status of the nebulizer adapter can be determined in detail.

- the main power supply may be once turned on and the control pattern H may be transitioned in a state where the heater is sufficiently low in temperature.
- the control pattern A is in a state where the power source P and the outlet C are separated in the state of the control pattern C or H. Since the locking plunger 89 of the locking mechanism 80 is held in the previous state even when the power is turned off, the locking plunger 89 is held in the contracted state of FIG. 34, and the locking mechanism 80 can be unlocked. .
- the control pattern B is a state in which the power supply P and the outlet C are divided in the state of the control patterns D, E, F, and G. Since the locking plunger 89 of the locking mechanism 80 is held in the previous state even when the power is turned off, the locking plunger 89 is held in the extended state of FIG. 35 and the locking mechanism 80 cannot be unlocked. . In order to enable unlocking in this state, it is only necessary to turn on the main power supply and make a transition to the control pattern H while the heater is sufficiently cold.
- the position, size (dimension), shape, material, orientation, quantity, and the like of each component can be changed as appropriate.
