Although the present invention is not shown in the drawings, the heated air generated by the hot air generator is also introduced into the drying furnace, and a drying apparatus for drying the object to be dried by using hot air and microwave at the same time. Therefore, although not shown in the drawings, it is assumed that a hot air generator is provided.

The operation of the drying control apparatus using the microwave shield section temperature according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, the manager sets the temperature through the temperature setter 152 of the inlet temperature controller 150 and the temperature setter 162 of the outlet temperature controller 160 in order to optimally dry the object to be dried. . The temperature set here is preferably set according to the amount of water (for example, yellow 0.5%, red 1.5-7%) according to the type of the drying object and the color of the paint pigment applied to the drying object. The present inventors have obtained a result of the drying failure when the outlet temperature is 80 ℃ or less through a number of experiments, it is preferable to set the inlet and outlet temperature to 80 ℃ or more according to the product when applied to the actual product Do. In order to set the set temperature more conveniently, it is preferable to use the method of acquiring the set temperature for each product in advance by experiment and pasting the set temperature of the product around the temperature setter using a sticker or the like.

In a state in which a setting temperature for controlling the drying of a drying object is set through a process as is well known, when the drying control device is operated, the controller 170 may include an optical sensor installed at the inlet and the outlet of the drying furnace 110. Check the location of the building through the. This is to drive the hot air dryer and the magnetron only when the dry matter enters the drying furnace.

When the dry matter flows into the drying furnace 110, the controller 170 automatically controls the drying controller according to the inlet and outlet temperatures detected by the inlet temperature controller 150 and the outlet temperature controller 160.

Here, the inlet and the outlet shielding section is set at the inlet and the outlet of the drying control device 100 to prevent the microwaves from the magnetron outflow, the shielding material such as ferrite is provided in the inlet and outlet shielding section. . The shielding material installed in the inlet shielding section is called the inlet shielding member 120, and the shielding material provided in the outlet shielding section is called the outlet shielding member 130.

That is, the temperature sensor is mounted in the inlet shield section and the outlet shield section, respectively.

The controller 170 drives only the magnetron provided at the front end of the drying furnace 110 when the initial dry matter flows into the drying furnace 110. After that, the controller 170 determines that the dry matter is located at the rear end. In this case, the magnetron provided at the rear end of the drying furnace 110 is also driven. The reason why the magnetron is selectively driven is to prevent the unnecessary waste of the power by driving the magnetron unnecessarily at the rear end without the construction, and at the same time to prevent the microwaves from entering the magnetron and damaging the magnetron. . In addition, in the case of the rear end without the initial dry matter, the generated microwave is applied to the outlet shield 130 in a large amount, thereby causing a problem of damaging the outlet shield 130. The magnetron installed at the rear end of the furnace 110 is not driven. Herein, the method of driving the magnetron located at the rear end is preferable to turn off the light sensor for a predetermined time when a dry object enters the entrance of the drying furnace, and to drive the magnetron after the set time passes.

The event generation control signal is extracted from the memory 151 according to the calculated temperature difference. If the detected temperature is lower than the set temperature, the operation for calculating the temperature difference is not performed. In this case, when the operation of the magnetron is turned off, there is a possibility that a drying failure may occur after drying of the object to be dried, and the shielding material may not be damaged by the generated microwaves.

If the detected temperature is higher than the set temperature, the difference is calculated by comparing the detected temperature with the set temperature, and the corresponding event generation control signal is extracted from the memory 151 according to the calculated difference.

In the case of 30 ° C. or less, event level information is classified as in event level 3.

Accordingly, the temperature comparator 153 extracts a corresponding event generation control signal from the memory 151 and transmits the corresponding event generation control signal to the event generator 154 according to the calculated temperature difference, and the event generator 154 responds to the event generation control signal transmitted. According to the event generation signal is transmitted to the controller 170.

In addition, the temperature comparator 163 of the outlet temperature controller 160 compares the temperature set by the temperature setter 162 with the temperature detected by the second temperature sensor 142 and calculates the difference. The event generation control signal is extracted from the memory 161 according to the calculated temperature difference. If the detected temperature is lower than the set temperature, the operation for calculating the temperature difference is not performed. In this case, when the operation of the magnetron is turned off, there is a possibility that a drying failure may occur after drying of the object to be dried, and the shielding material may not be damaged by the generated microwaves.

If the detected temperature is higher than the set temperature, the difference is calculated by comparing the detected temperature with the set temperature, and the corresponding event generation control signal is extracted from the memory 161 according to the calculated difference. The event generation control signal may include event level information for selectively controlling a magnetron provided at a rear end of a drying furnace among the plurality of magnetrons according to the temperature difference, and the memory 161 may include a plurality of different event generation control signals. Stored. The event level information is to set the event level according to the temperature difference in order to selectively turn off or drive the magnetron provided in the rear stage in accordance with the calculated temperature difference. For example, when the difference between the detected temperature and the set temperature is 10 ° C. or less, the event level 1, when the difference between the detected temperature and the set temperature is 10 ° C. or more and 20 ° C. or less, the difference between the event level 2 and the detected temperature and the set temperature is 20 ° C. or more. In the case of 30 ° C. or less, event level information is classified as in event level 3.

Accordingly, the temperature comparator 163 extracts the corresponding event generation control signal from the memory 161 according to the calculated temperature difference, and transmits the event generation control signal to the event generator 164, and the event generator 164 receives the event generation control signal. According to the event generation signal is transmitted to the controller 170. The event occurrence signal includes exit classification information, a signal informing the event, and event level information.

The controller 170 collects event generation signals output from the inlet temperature controller 150 and the outlet temperature controller 160 in the event collector 171 and transmits them to the event analyzer 172.

The event analyzer 172 classifies the event generation signal into the inlet or the exit signal by the inlet or the outlet classification information included in the transmitted event generation signal, extracts the event level information included in the event generation signal, and the magnetron controller 173. To pass on. For example, the data indicating the entrance or the exit and the event level information are combined and transmitted to the magnetron controller 173 as one detection information. Since two detection information are generated here for the entrance and the exit, it is assumed that the event analyzer 172 transfers the entrance detection information to the magnetron controller 173 first, and then the exit detection information to the magnetron controller 173 for convenience. do.

When the event information according to the temperature detection is transmitted, the magnetron controller 173 extracts a magnetron control signal corresponding to the event level information from the memory 174 and transmits the magnetron control signal to the magnetron driver 175 as a magnetron driving control signal. At this time, the magnetron driving control signal is divided into a first magnetron driving control signal for controlling the magnetron provided at the front of the drying furnace, and a second magnetron driving control signal for controlling the magnetron provided at the rear end of the drying furnace.

The magnetron driver 175 selectively drives the magnetrons provided at the front and rear ends of the drying furnace 110 according to the transmitted first magnetron driving control signal and the second magnetron driving control signal.

For example, the magnetron provided at the front end of the drying furnace is driven according to the first magnetron driving control signal, wherein the magnetron provided at the front end drives all or only some or all of the magnetrons according to event level information.
