生量を多くするように制御されていた。[Prior Art] In recent years, fresh foods and the like have been stored for a relatively long period of time, and an ozonizer is installed in a storage room for foods and the like for the purpose of processing odors generated from the foods and sterilizing spoilage bacteria. However, ozone is sent into the storage to perform sterilization and deodorization. Conventionally, as shown in FIG. 3, the ozonizer 21 is installed in a storage cabinet 23 in which a preserved product 22 such as food is stored, and the ozone concentration in the storage cabinet 23 is detected by an ozone sensor 24. The ozonizer control device 25 drives and controls the ozonizer 21 so that the ozone concentration becomes a preset concentration.
The ozonizer 21 is configured so that the amount of ozone generated can be adjusted, and if the ozone concentration in the storage 23 is high, the ozonizer 21
It was controlled so that the ozone generation amount of 21 was decreased and the generation amount was increased if the ozone concentration was low.

いう問題がある。[Problems to be Solved by the Invention] It is known that the ozone yield of an ozonizer is easily affected by the dew point (humidity) of the raw material air and the ambient temperature. For example, the relationship shown in Figs. 7,3 (1983) 150-1
Reported in 58. 4 is a diagram showing the relationship between the dew point of the source gas and the ozone yield, and FIG. 5 is a diagram showing the relationship between the cooling water temperature and the ozone yield. However, W represents the electric power used (watt / minute), and Qx represents the amount of ozone generated (mg). However, in the conventional device, the ozonizer control device 24 detects the ozone concentration in the storage 23 by the detection signal from the ozone sensor 24, and the storage 23 is adjusted so that the concentration becomes the set concentration.
The ozone generation amount of the ozonizer 21 was adjusted regardless of the temperature and humidity inside. Therefore, not only does it take time for the inside of the storage cabinet 23 to reach a predetermined ozone concentration, but also the ozone generation amount of the ozonizer 21 is frequently changed.
There is also the inconvenience that the durability of 21 becomes short. In particular, the ozone concentration, temperature, and temperature inside the storage box change significantly when the storage box is opened and closed and the storage box is opened and closed. Therefore, hunting takes a long time to return to the desired concentration and stabilize. There is.
オゾンO3の殺菌、脱臭作用は次式によりオゾンO3が分
解した時に生じる発生期の酸素Ｏが腐敗菌や臭いの分子
を酸化することにより行われる。Sterilization of ozone O 3, the deodorization is carried out by oxygen O nascent caused when ozone O 3 was decomposed by the following equation is oxidized molecules of spoilage bacteria and odors.
O3＝O2＋Ｏ 従って、臭いを多く発生する保存物を保管した場合に
は保存物の量が同じであってもオゾンO3が余計に消費さ
れるため、オゾン発生量を多くする必要があるが、従来
装置ではそのような配慮がなされていなかった。O 3 ＝ O 2 ＋ O Therefore, when a stored product that generates a lot of odor is stored, ozone O 3 is consumed extra even if the stored amount is the same, so it is necessary to increase the ozone generation amount. However, such a consideration has not been made in the conventional device.

An object of the present invention is to provide a drive control device for an ozonizer that can adjust the concentration in a short time.

駆動制御する。The calculating means calculates the operating condition of the ozonizer based on the data stored in the storage device and the detection signal from each sensor so that the ozone concentration in the storage reaches the target ozone concentration, and the calculated operating condition. The predicted ozone concentration is calculated by calculating the ozone concentration after the operation for a predetermined time. The first drive control means drives and controls the ozonizer under the operating conditions calculated by the calculation means, and the comparison means measures the actual ozone concentration in the storage after the lapse of the predetermined time by the sensor. With the predicted ozone concentration. If the difference between the actual ozone concentration and the predicted ozone concentration is larger than a predetermined value, the second drive control means, based on the comparison result, causes the calculation means to calculate the operating condition again and newly obtains it.

に調整することができる。Therefore, the optimum operating condition of the ozonizer in which the ozone concentration in the storage reaches the target ozone concentration is determined in consideration of the relationship between the ozone generation efficiency of the ozonizer and the temperature and humidity, and the ozonizer is drive-controlled according to the operating condition. Therefore, the time required for the ozone concentration in the storage to reach the target ozone concentration can be shortened. In addition, when the expected ozone concentration after a predetermined time under any operating condition considering temperature and humidity is calculated and compared with the actual ozone concentration after a predetermined time, and the comparison result is significantly different, for example, opening / closing the storage Since the operating condition of the ozonizer is changed only when the temperature and humidity change significantly due to
The operating conditions will not be set carelessly, and if the temperature and humidity change significantly, the operating conditions will be corrected to linearly approach the target ozone concentration. The target ozone concentration can be adjusted in a shorter time.

する。The ozonizer 1 is operated with an applied voltage commanded by a drive signal from the control device 7. The CPU 8 compares the measured value and the set value of the ozone concentration in the storage 3 after a predetermined time has elapsed after outputting the drive signal to the ozonizer 1. If the ozone concentration is equal to the set value, the CPU 8 does not output a new drive signal to the ozonizer 1, and the ozonizer 1 continues to operate under the previous operating conditions. On the other hand, when the measured value and the set value of the ozone concentration are different from each other, the CPU 8 outputs a drive signal for increasing or decreasing the applied voltage to the ozonizer 1 regardless of the temperature and the humidity if the difference is small and is less than the predetermined value. . When the difference is larger than the predetermined value, the CPU 8 measures the temperature and humidity in the storage 3 by the detection signals from the temperature sensor 4 and the humidity sensor 5, and based on the result, increases or decreases the ozone generation amount. The value is calculated and a new drive signal is output to the ozonizer 1 so that the ozonizer 1 operates at the applied voltage that is the ozone generation amount.
