Accordingly, since the hot air discharged from the branch pipe 521 collides with each other in a state of causing a tornado, it is spread more rapidly throughout the drying space 12 to increase drying efficiency.

The humidity sensor 53 is formed in each of the plurality of discharge pipes 52 to measure the humidity of the hot air, and the operation of the dehumidifying unit 2 may be made according to the measured humidity, and the humidity does not reach the set humidity. If not, the discharge pipe 52 is closed to prevent a decrease in drying efficiency with high humidity air.

If it is not reached, the opening/closing module 55 is closed to block the supply of hot air through a specific exhaust pipe 52 . For example, the opening/closing control module 63 may close the opening/closing module 55 when the temperature is lower than the reference value or the humidity is higher than the reference value. The hot air supply unit 5 supplies hot air evenly throughout the drying space 12 through a plurality of discharge pipes 52, and hot air with a low temperature or high humidity is supplied through a specific discharge pipe 52. In this case, the overall drying efficiency is reduced.

In addition, the monitoring unit 7 not only detects the occurrence of an abnormality in the dehumidifying unit 2 or the temperature increasing unit 3, but also predicts the abnormal time before the abnormal occurs through its unique configuration, and the abnormal time is predicted. It can detect performance degradation even before, so that countermeasures can be made more quickly. To this end, the monitoring unit 7 may include an abnormality diagnosis unit 71 , an abnormality prediction unit 72 , and a performance degradation detection unit 73 .

The abnormality diagnosis unit 71 is configured to diagnose an abnormality of the dehumidifying unit 2 or the temperature increasing unit 3, and 'abnormal' means that the dehumidifying unit 2 or the temperature increasing unit 3 continues to operate. It means a fault condition in which normal operation is impossible to an extent that cannot be achieved. When the difference between the humidity or temperature measured by the humidity sensor 53 or the temperature sensor 54 and the set reference value exceeds a predetermined value, the abnormal diagnosis unit 71 is configured to include the dehumidifying unit 2 or the temperature increasing unit 3 to be diagnosed as abnormal.

The abnormality predicting unit 72 was not diagnosed as an abnormality in the dehumidifying unit 2 or the temperature increasing unit 3 by the abnormality diagnosis unit 71, but the temperature or humidity in a specific range including the reference value for a certain period of time or more If it is maintained, predict the timing of the occurrence of anomalies. In other words, the abnormality predicting unit 72 cannot be considered that heating or dehumidification is normally being performed when the temperature is above the reference value or the humidity is below the reference value, but continues for more than a certain time in a specific range including the reference value. ) or the performance of the temperature rising unit 3 starts to deteriorate, which means that the time for the occurrence of an abnormality has arrived, and the timing of the occurrence of the abnormality can be predicted by statistical analysis. To this end, the abnormality prediction unit 72 may include an error calculation module 721 , a duration measurement module 722 , an abnormality index calculation module 723 , and an abnormality prediction notification module 724 .

The error calculation module 721 is configured to calculate an error between temperature or humidity and a reference value, and when the calculated error reaches a specific range including the reference value, it calculates and monitors the error in real time.

The duration measuring module 722 is configured to measure the duration when the error with the reference value of temperature or humidity reaches a specific range, and allows an abnormality index to be calculated according to the duration.

The abnormality index calculation module 723 is configured to calculate the abnormality index according to the degree of error and the duration, and the abnormality index may exhibit a higher value as the error increases and the duration is longer. For example, the abnormality index calculation module 723 may calculate an abnormality index by multiplying the value of the error and the duration, and the higher the abnormality index, the higher the risk of abnormality occurring in a short time.

The abnormality prediction notification module 724 is a configuration that provides information on a time when abnormality is highly likely to occur according to the abnormality index calculated by the abnormality index calculation module 723, and the abnormality is likely to occur according to the abnormality index A high time point is set in advance so that an abnormal occurrence time point can be predicted accordingly. The timing information according to the anomaly index can be set based on experimental or historical data. For example, by dividing the anomaly index into 10 sections, within 10 days in the case of the highest section 1, within 20 days in the case of the second section, etc. According to each section of the anomaly index, it is possible to predict and provide a time when the risk of abnormality is high.

The performance degradation diagnosing unit 73 is the rate of change of the error between the temperature or humidity and the reference value even when the abnormality is diagnosed by the abnormality diagnosis unit 71 or the abnormality risk point is not predicted by the abnormality predictor 72 . Accordingly, the performance degradation of the dehumidifying unit 2 or the temperature increasing unit 3 can be diagnosed. In other words, the performance degradation end unit 73 means that when the temperature or humidity exceeds the reference value and does not stay in a specific range for more than a certain time, but the error with the reference value sharply increases, performance degradation or temporary abnormality occurs Therefore, it is possible to take a preemptive response to this. To this end, the performance degradation end unit 73 may include a change rate calculation module 731 , a change rate comparison module 732 , a time measurement module 733 , and a performance deterioration notification module 734 .

The rate of change calculation module 731 is configured to calculate a rate of change with respect to an error between temperature or humidity and a reference value, and may calculate a slope at which the error changes at regular time intervals.

The rate of change comparison module 732 compares the rate of change calculated by the rate of change calculation module 731 with a set threshold, and measures the duration when the calculated rate of change exceeds the threshold.

The time measuring module 733 is configured to measure the duration when the rate of change exceeds a threshold value, so that performance degradation can be notified according to the duration.

The performance degradation notification module 734 is configured to diagnose and notify the deterioration of the performance of the dehumidifier 2 or the temperature increase unit 3 when the rate of change exceeding the threshold continues for more than a set time, and the dehumidification unit 2 Alternatively, the state of the temperature increasing unit 3 is checked and its operating performance can be improved.

The heat circulation unit 8 is configured to circulate the heat of the air discharged through the blower 4 to supply it to the air introduced through the outdoor air inlet pipe 11, and to circulate the discharged air directly. Rather, it enables the reuse of heat alone. Therefore, the heat circulation unit 8 can eliminate the effect of salt contained in the air discharged through the blower 4, and supply the heat of the discharged air to the incoming air, and to reduce power consumption. To this end, the thermal circulation unit 8 may include a circulation pipe 81 and an additional blowing module 82 .

In addition, the circulation pipe 81 completely surrounds the outside air inlet pipe 11 while minimizing the influence on the outside air flowing through the outside air inlet pipe 11 to the opposite side to the inlet of the outside air inlet pipe 11. It can be bent to exhaust the circulated air. To this end, the circulation pipe 81 may include an inlet pipe receiving part 811 and a bent outlet 812 .

The inlet pipe accommodating part 811 is formed on the circulation pipe 81 to completely surround the outdoor air inlet pipe 11, and as shown in FIGS. 8 to 9, the outdoor air inlet pipe 11 is formed at a predetermined depth as shown in FIGS. The heat of the circulating air can be effectively transferred into the outdoor air inlet pipe 11 by making it close in a completely enclosed state. In addition, the inlet pipe accommodating part 811 may block contact with the outdoor air inlet pipe 11 even when the external environment is cold to further increase the thermal efficiency of the drying apparatus.

The bent discharge part 812 is bent to the opposite side to the inlet of the outdoor air inlet pipe 11 at the end of the circulation pipe 81 to discharge the circulated air, and the circulated air passes through the outdoor air inlet pipe 11. Avoid mixing with incoming outside air.
