Description

[0001] The present invention relates to a high-efficiency sterilizing dryer and a method of controlling the same,

The present invention relates to a sterilizing and drying device for drying and disinfecting clothes, clothes, and other articles, and more particularly, to a sterilizing and drying device for drying clothes and other articles such as hygiene clothes and work clothes worn in laboratories and hospitals by hot air and sterilizing various bacteria by ultraviolet rays Dryer.

Generally, doctors of hospitals or researchers of research institutes wear clothing such as hygiene and work clothes for hygiene and safety. It is necessary to wash and sterilize used clothes and other items after wearing them because clothes and other used items once worn can be contaminated with various contaminants and bacteria that can cause various diseases may multiply. Therefore, in hospitals and laboratories, the clothes used are first washed, and then the clothes and other items are sterilized by using an ultraviolet sterilizer.

In general, the inside of the ultraviolet sterilizer is provided with a fan for circulating the humid air inside the sterilizer to the outside air, and the inside of the sterilizer for lowering the humidity of the inside of the ultraviolet sterilizer, because the humidity increases rapidly and the sterilizing efficiency becomes low. A heater for heating the air to be supplied is provided. A common ultraviolet sterilizer operates the heater and the fan at the same time to lower the internal humidity. The fan sucks the outside air and supplies it to the inside of the ultraviolet sterilizer. The heater heats the air sucked by the fan to raise the internal temperature of the ultraviolet sterilizer, thereby quickly reducing the internal humidity of the ultraviolet sterilizer.

The conventional ultraviolet sterilizer has a problem in that the heater is continuously operated to lower the internal humidity of the ultraviolet sterilizer while the ultraviolet sterilizer is operating, thereby consuming a large amount of electric power. Also, since the internal temperature of the ultraviolet sterilizer is continuously increased due to the continuous operation of the heater, the disinfection object located inside the ultraviolet sterilizer may be damaged, and further fire may occur.

The present invention provides a highly efficient sterilizing dryer capable of minimizing the energy consumption of the heater by turning on and off the heater of the sterilizing dryer based on the internal temperature and the internal humidity of the sterilizing dryer. Further, the present invention is not limited to the above-described technical problems, and another technical problem may be derived from the following description.

By minimizing the use of heaters, which are highly power-consuming heaters, the energy efficiency can be increased and the internal humidity of the sterilizing dryer, which affects the efficiency of sterilization, can be rapidly reduced. Thus, the same sterilization drying effect can be achieved while using low energy as compared to a conventional sterilizing dryer in which the heater is continuously turned on during sterilization drying.

The control box 37 is installed on the upper surface of the diaphragm 20 to expose the control panel operated by the user and controls various values for controlling the operation of the sterilizing dryer such as the operation time of the sterilizing dryer, Adjust. The control box 37 controls the operation of the fan 31, the plasma ionizer 32, the heater 33 and the ultraviolet lamp 35. The control box 37 controls the on / off operation of the sterilizing dryer fan 31, the heater 33 and the ultraviolet lamp 35 as described below. The operation of the fan 31, the heater 33 and the ultraviolet lamp 35 according to the control box 37 will be described in detail below.

FIG. 5 is a flowchart illustrating an operation control method of a sterilizing dryer according to an embodiment of the present invention. Referring to FIG. 5, the operation control method of the sterilizing dryer according to the present embodiment includes the following steps, which are performed in a time-series manner in the control box 37 of the sterilizing dryer shown in FIGS. According to the following embodiments, the control box 37 of the sterilizing dryer includes a heater 33 for raising the internal temperature of the sterilizing dryer in accordance with at least one of the internal temperature and the internal humidity of the sterilizing dryer, The fan 31 for lowering the humidity, and the ultraviolet lamp 35 for sterilizing the object located inside the sterilizing dryer. The sterilizing of the sterilizing dryer shown in FIGS. 1-4 is basically performed by sterilizing the ultraviolet lamp 35, and the plasma ionizer 32 serves to supplement the sterilization of the ultraviolet lamp 35. The plasma ionizer 32 can be turned on and off when the ultraviolet lamp 35 is turned on and off.

In step 501, the control box 37 of the sterilizing dryer confirms whether the operation mode of the sterilizing dryer is the continuous operation mode. The user of the sterilizing dryer places the object inside the housing 10 of the sterilizing dryer in the upper hook 53 and / or the lower hook 54, closes the door 11 of the housing 10, The operation of the sterilizing dryer starts. The sterilizing dryer can operate in different modes depending on the user's choice. The user may select a timer operation mode in which the sterilizing dryer operates only for a certain period of time or may select a continuous operation mode in which the user operates until the sterilizing dryer is stopped. As a result, if the operation mode of the sterilizing dryer is the continuous operation mode, the flow proceeds to step 502; otherwise, the flow proceeds to step 503.

In step 502, the sterilizing dryer operates in a continuous operation mode. A detailed description of the continuous operation mode will be described in detail below with reference to FIG. 8.

In step 503, the control box 37 of the sterilizer dryer turns on the heater 33, the fan 31, and the ultraviolet lamp 35 and starts counting the timer of the sterilization drying processor. When the sterilization and drying process of the sterilizing dryer starts, the control box 37 of the sterilizing dryer turns on the heater 33 of the sterilizing dryer, the fan 31 and the ultraviolet lamp 35 to raise the internal temperature of the sterilizing dryer The humid air inside is circulated with the outside air to remove the inside humidity. Since the user has operated the control box 37 so that the sterilizing dryer is operated only for a certain period of time, the control box 37 of the sterilizing drier is controlled by a timer (for example, 2 hours or 3 hours) Start counting. The sterilization drying time means the time for sterilizing and drying the object inserted into the housing of the sterilizing dryer.

In step 504, the control box 37 of the sterilizing dryer monitors whether the internal temperature of the sterilizing dryer is above the reference temperature during the warm-up of the heater 33, the fan 31 and the ultraviolet lamp 35. As described above, the temperature sensor 52 for measuring the internal temperature of the sterilizing dryer is located inside the housing 10 of the sterilizing dryer. The fan 31 located in the upper space of the housing 10 operates and sucks the air outside the housing 10 and supplies the air to the inside of the housing 10 through the vertical tube 41. [ The heater 33 heats the sucked outside air and discharges the sucked air through the rear side wall of the housing 10 and the opening of the depression of the diaphragm 20. [ The control box 37 of the sterilizing and drying machine is sterilized by using the temperature sensor 52 located inside the housing 10 so that the temperature of the inside of the sterilizing and drying machine is gradually increased by supplying the heated outside air to the inside of the housing 10, Monitor whether the internal temperature of the dryer is above the reference temperature.

Since the heater 33 and the fan 31 continue to operate while the control box 37 of the sterilizer drier monitors the internal temperature of the sterilizer dryer, the internal temperature of the sterilizer dryer is It will continue to rise. If the internal temperature of the sterilizing dryer becomes too high, there is a risk that the object of the sterilizing dryer may be damaged due to high temperature or fire may occur. Further, since the heater 33, which is an electric heater, consumes a lot of electric power, the continuous use of the heater 33 is not preferable from the viewpoint of energy efficiency. Accordingly, in order to prevent excessive use of the heater 33, the heater 33 can be turned off when the internal temperature of the sterilizing dryer reaches a predetermined reference temperature or higher. For example, the user can preset the reference temperature to 60 占 폚. If the internal temperature of the sterilizing dryer is higher than the reference temperature, the process proceeds to step 505. If the internal temperature of the sterilizing dryer is lower than the reference temperature, the internal temperature of the sterilizing dryer is continuously monitored.

In step 505, while monitoring the internal temperature of the sterilizing dryer, if the internal temperature of the sterilizing dryer is higher than the reference temperature, the control box 37 of the sterilizing dryer turns off the heater 33 and starts counting the timer of the humidity driving mode . Since the internal temperature of the sterilizing dryer has reached a preset reference temperature, the control box 37 of the sterilizing dryer turns off the heater 33. [ However, since the internal temperature of the sterilizing drier rises and the internal humidity of the sterilizing drier has not yet lowered to a certain level or lower, the fan 31 is kept in the ON state to lower the humidity inside the sterilizing drier. The control box 37 of the germicidal drier performs a humidity operation mode for controlling the heater 33 on and off in accordance with the change in the internal humidity of the sterilizing and drying device and a timer (for example, 30 minutes) Start counting.

The sterilizing dryer operates in the humidity operation mode during the timer of the preset humidity operation mode. The timer in the humidity operation mode is the maximum time for the sterilizer dryer to operate in the humidity operation mode. When the timer of the humidity operation mode is completed, the sterilizer dryer no longer operates in the humidity operation mode and operates in the temperature and humidity operation mode. And terminates. The set time of the timer of the humidity driving mode may be arbitrarily inputted by the user or may be set by the control box 37 of the sterilizing drier. The setting time of the timer in the humidity driving mode will be described in detail below with reference to Figs. 10-12.

In step 506, the sterilizing dryer operates in the humidity driving mode. While the timer of the humidity operation mode is being counted, the heater 31 is repeatedly turned on and off so that the internal temperature of the sterilization drying converges to the reference temperature while the fan 31 and the ultraviolet lamp 35 are kept on, When the temperature is lower than the lower limit humidity, repeats the on-off repetition of the heater and maintains the heater 33 off. In the humidity operation mode, the heater 33 is turned on and off based on a change in the internal temperature of the sterilizing dryer, and the heater 33 is turned off regardless of the internal temperature when the internal humidity of the sterilizing drier is lower than the lower limit humidity.

The sterilizing dryer according to the present embodiment repeats the on / off operation of the heater 33 based on the internal temperature so as to keep the internal temperature of the sterilizing dryer at or above the reference temperature for quickly lowering the internal humidity of the sterilizing dryer during the humidity operation mode. When the internal humidity of the sterilizing dryer is lowered to a predetermined lower limit humidity or lower during the execution of the humidity driving mode, the internal humidity of the sterilizing dryer is adjusted to a humidity suitable for sterilization, so that the heater 33 is turned off regardless of the internal temperature of the sterilizing dryer . Accordingly, the sterilizing and drying device can quickly reduce the internal humidity of the sterilizing and drying device, while minimizing the operation time of the heater 33 while controlling the inside of the sterilizing and drying device to an environment suitable for sterilization, thereby reducing energy consumption.

The humidity operation mode is performed by the control box 37 of the sterilizing dryer during the preset time of the humidity operation mode. When the timer set time of the humidity operation mode has elapsed, the humidity operation The execution of the mode is terminated. Depending on the mode of operation of the sterilizer dryer, the sterilizer dryer may perform a temperature / humidity operation mode after termination of the humidity operation mode or stop the operation of the sterilizer dryer.

The detailed description of the step of performing the humidity driving mode will be described in detail in the description related to Fig. 6 is a detailed flowchart of the step of performing the humidity operation mode shown in FIG. Referring to FIG. 6, the humidity operation mode may be composed of the following steps. In step 5061, the control box 37 of the sterilizer dryer monitors whether the internal humidity of the sterilizer dryer is below the upper limit humidity (e.g., 20%). Since the fan 31 of the sterilizing dryer is kept warm during the humidity driving mode, the internal humidity of the sterilizing dryer is kept low. The control box 37 of the sterilization dryer determines whether the internal humidity of the sterilizing dryer is below the upper humidity limit while continuously monitoring the internal humidity of the sterilizing dryer.

The upper limit humidity is an upper limit value of the humidity at which the sterilizing dryer can perform sterilization of the object. In the case where the sterilization is performed at the upper humidity limit or higher, the sterilization of the object is not properly performed and the bacteria are likely to be present. The user can not wear or use the object comfortably. Thus, the control box 37 of the sterilizing dryer maintains the ON state of the fan 31 while the timer of the humidity operation mode is counted and repeatedly turns on and off the heater 33 according to the internal temperature of the sterilizing dryer, Lower the internal humidity of the dryer. As a result of the monitoring, if the internal humidity of the sterilizing dryer is less than the upper limit humidity, the process proceeds to step 5062; otherwise, the process proceeds to step 5063.

In step 5062, the control box 37 of the sterilizing dryer checks whether the internal humidity of the sterilizing dryer is equal to or lower than the upper limit humidity, and whether the internal humidity of the sterilizing dryer is maintained below the upper humidity limit for a predetermined time (for example, one minute). The internal humidity of the sterilizing dryer is measured by a humidity sensor 51 located inside the housing 10 and is measured according to various causes such as the amount of water vapor contained in the air passing around the humidity sensor 51, The internal humidity can be changed in real time. Accordingly, in order to accurately measure the internal humidity, the control box 37 of the sterilizing dryer confirms whether the internal humidity of the sterilizing dryer is maintained below the upper humidity for a predetermined time or longer when the internal humidity of the sterilizing dryer is lower than the upper humidity. The predetermined time for confirming whether or not the internal humidity is maintained may be set to an appropriate value based on the specifications of the fan 31, the heater 33 and the like, the kind of the sterilizing object, and the like. If it is determined that the internal humidity of the sterilizing dryer has remained below the upper limit humidity for a predetermined time or longer, the process proceeds to step 507; otherwise, the process returns to step 5061.

In step 5063, the control box 37 of the sterilizing dryer checks whether the timer of the humidity operation mode has been counted when the internal humidity of the sterilizing dryer is higher than the upper humidity. As described above, the timer of the humidity operation mode is the maximum time for the sterilizing dryer to operate in the humidity operation mode. If the timer of the humidity operation mode is completed and the internal humidity of the sterilizing dryer is higher than the upper humidity, And operates in a different operating mode. Thus, the sterilizing drier is prevented from operating in the humidity operation mode beyond the timer in the humidity operation mode. If it is determined that the timer of the humidity driving mode has been counted, the flow proceeds to step 507. Otherwise, the flow returns to step 5061. [

According to steps 5061-5063, the sterilizing dryer is operated when the internal humidity of the sterilizing dryer is maintained for a certain period of time (for example, 1 minute) or less under the upper humidity (for example, 20% When the counting of the timer is completed, the execution of the humidity driving mode is terminated. The sterilizing and drying device according to an embodiment of the present invention can end the humidity operation mode and switch to the temperature / humidity operation mode when the internal humidity of the sterilizing / drying device is maintained below the upper limit humidity for a predetermined time. Also, the sterilizing dryer according to an embodiment of the present invention can switch to the temperature / humidity operation mode when the timer of the humidity operation mode is completed even when the internal humidity of the sterilizing dryer is higher than the upper humidity. The sterilizing dryer according to an embodiment of the present invention operates in the humidity operation mode during the timer of the maximum humidity operation mode and when the timer of the humidity operation mode is completed, the internal humidity of the sterilizing / The operation of the humidity operation mode is terminated even if the upper limit humidity is higher than the upper limit humidity.

In step 507, the control box 37 of the sterilizing dryer confirms whether the timer of the sterilizing drying time has been counted. The control box 37 of the sterilizing dryer confirms whether or not the counting of the timer of sterilization drying time is completed after the end of the humidity operation mode. The control box 37 of the sterilizer dryer confirms that the counting of the timer of sterilization drying time has been completed in order to ensure that the object put into the sterilizer dryer is sterilized and dried during the timer of the sterilization drying time input by the user. If it is determined that the timer for the sterilization drying time has been completed, the process proceeds to step 509; otherwise, the process proceeds to step 508.

In step 508, the control box 37 of the sterilizing dryer switches the operation mode of the sterilizing dryer from the humidity operation mode to the temperature / humidity operation mode when the timer of the sterilization drying time is not completed after performing the humidity operation mode, . If the timer of sterilization drying time is not completed, the control box 37 of the sterilizing dryer operates the sterilizing dryer in the temperature and humidity operation mode until the timer of sterilization drying time is completed. The temperature and humidity operation mode of the sterilizing dryer will be described in detail below with reference to FIG.

In step 509, when the sterilization drying time timer is completed, the control box 37 of the sterilizing dryer monitors whether the internal humidity of the sterilizing dryer is below the lower humidity (for example, 5%). The lower limit humidity refers to the humidity at which the sterilizing dryer has finished drying, and may be set to an appropriate value based on the specifications of the fan 31, the heater 33, etc., the kind of the sterilizing object and the like. If the internal humidity of the sterilizer dryer is below the lower humidity limit, proceed to step 510. Otherwise, continue monitoring whether the internal humidity of the sterilizer dryer is below the lower humidity limit. In step 509, since the temperature of the fan 31 is maintained, the internal humidity of the sterilizing dryer is continuously lowered. Thus, the control box 37 of the sterilizer dryer continuously monitors the internal humidity of the sterilizer dryer until the internal humidity of the sterilizer dryer is below the lower humidity limit.

In step 510, if the internal humidity of the sterilizing dryer is lower than the lower humidity, it is checked whether the internal humidity of the sterilizing dryer is maintained below the lower humidity for a predetermined time (for example, one minute). If it is determined that the internal humidity of the sterilizing dryer is lower than the lower limit humidity for a predetermined period of time, the process proceeds to step 512. Otherwise, the process proceeds to step 511.

In step 511, the control box 37 of the sterilizing dryer confirms whether the timer of sterilization drying time has passed the maximum germicidal drying period (for example, 4 hours). If the sterilizing drying time of the sterilizing dryer is not less than the maximum sterilization drying time even if the internal humidity of the sterilizing dryer is not maintained for a predetermined time (for example, 1 minute) or less at a lower limit humidity (for example, 5% To prevent the sterilizing dryer from operating for more than a preset maximum sterilization drying time. This embodiment prevents the sterilizer from operating for more than the maximum sterilization drying time to prevent overloading of the sterilizing dryer and excessive sterilization of the sterilizing object. The maximum sterilization drying time may be preset by the manufacturer and may be set differently depending on the climatic conditions of the area in which the device is being supplied.

If the internal humidity of the sterilizing dryer is kept below the lower limit humidity for a certain period of time at step 512, the control box 37 of the sterilizing dryer turns off the heater 33 of the sterilizing dryer and the ultraviolet lamp 35, After a lapse of time (e.g., 10 minutes), the fan 31 of the sterilizing dryer is turned off. Since the ultraviolet lamp of the sterilizing dryer operated during the sterilizing drying time and the internal humidity of the sterilizing dryer was lowered below the lower humidity limit, the control box 37 of the sterilizing dryer ended the sterilizing drying process. More specifically, the control box 37 of the sterilizing dryer turns off the heater 33 of the sterilizing dryer and the ultraviolet lamp 35. However, the control box 37 of the sterilizing / drying machine is provided with a fan 31 (see FIG. 1) for drying and drying the inside of the housing 10 of the sterilizing dryer during the finish drying time to discharge the heat and / or moisture remaining in the housing 10 of the sterilizing / And after the lapse of the finish drying time, the fan 31 is turned off, and the operation of the sterilizing dryer is terminated.

According to steps 509-512, the control box 37 of the sterilizing dryer controls the heater 33 and the ultraviolet lamp 30 when the internal humidity of the sterilizing dryer is kept below the upper limit humidity for a predetermined time or longer, (35) is turned off, and the fan (31) is turned off after the finish drying time has elapsed. When the inside humidity of the sterilizing dryer is lowered below the lower humidity and the state below the lower humidity is maintained for a predetermined time or more during the humidity operation mode, that is, when the drying and sterilization of the object of the sterilizing dryer is completed The operation of the sterilizing dryer is terminated by turning off the heater 33, the fan 31 and the ultraviolet lamp 35 of the sterilizing dryer. Accordingly, the energy consumption of the sterilizing dryer can be reduced by early termination of operation of the sterilizing dryer.

The control box 37 of the sterilizing dryer controls the temperature of the inside of the fan 31 and that of the ultraviolet lamp 35 while maintaining the temperature of the inside of the fan 31 and the temperature of the ultraviolet lamp 35 And performs a temperature and humidity operation mode in which the heater 33 is repeatedly turned on and off in accordance with at least one. The temperature and humidity operation mode is maintained for a predetermined time (for example, one minute) after the counting of the timer in the humidity operation mode is completed or the internal humidity of the sterilizing drier is lower than the upper humidity (for example, 20% If the time has not yet elapsed, it is carried out by a sterilizing dryer until the sterilization drying time has elapsed.

The temperature and humidity operation mode is performed after the execution of the humidity operation mode. In performing the temperature and humidity operation mode, the internal humidity of the sterilizing dryer is performed at a humidity lower than the initial humidity. Therefore, during the execution of the temperature and humidity operation mode, the control box 37 of the sterilizing dryer can appropriately sterilize the object of the sterilizing dryer even if the heater 33 of the sterilizing dryer is not frequently turned on.

7 is a detailed flowchart of a step of performing the temperature and humidity operation mode shown in FIG. Referring to FIG. 7, the temperature and humidity operation mode may include the following steps. In step 5081, the control box 37 of the sterilizer dryer monitors whether the internal humidity of the sterilizer dryer is below the lower limit humidity (e.g., 5%). As described above, the lower limit humidity is the lower limit of the humidity which does not need to further lower the internal humidity of the sterilizing dryer. When the sterilization is performed at a lower limit of the humidity, the object of the sterilizing dryer is almost dried, and the object is effectively sterilized. As described above, the sterilization efficiency is more affected by the internal humidity than the internal temperature of the sterilizing dryer. Therefore, when the internal humidity of the sterilizing dryer is lower than the lower humidity, efficient sterilization can be performed irrespective of the internal temperature of the sterilizing dryer. If the internal humidity of the sterilizing dryer is lower than the lower limit humidity, the process proceeds to step 5086. Otherwise, the process proceeds to step 5082.

In step 5082, the control box 37 of the sterilizing dryer monitors whether the internal humidity of the sterilizing dryer is above a moderate humidity (for example, 8%) if the internal humidity of the sterilizing dryer is higher than the lower humidity. The control box 37 of the sterilizer dryer compares the internal humidity with the intermediate humidity while monitoring the internal humidity of the sterilizer dryer. The intermediate humidity is a temperature between the upper limit humidity and the lower limit humidity, and is a reference temperature for judging whether to turn on the heater 33 of the sterilizing dryer in order to rapidly lower the internal humidity of the sterilizing dryer. As a result of the monitoring, if the internal humidity of the sterilizing and drying machine is more than the intermediate humidity, the process proceeds to step 5083; otherwise, the process proceeds to step 5086.

In step 5083, the control box 37 of the sterilizing dryer checks whether the internal humidity of the sterilizing dryer is maintained for a predetermined time (for example, one minute) or more if the internal humidity of the sterilizing dryer is equal to or higher than the intermediate humidity . When the internal humidity of the sterilizing dryer is lower than the intermediate humidity, the heater 33 of the sterilizing dryer does not need to be turned on. On the other hand, if the internal humidity of the sterilizing dryer is maintained above the intermediate humidity for a certain period of time, it is necessary to decide whether or not to turn on the heater 33 of the sterilizing dryer, which affects the internal humidity of the sterilizing dryer. If it is determined that the internal humidity of the sterilizing and drying machine is higher than the intermediate humidity for a certain period of time, the process proceeds to step 5084; otherwise, the process proceeds to step 5086.

In step 5084, if the internal humidity of the sterilizing dryer is maintained above the intermediate humidity for a certain period of time, the control box 37 of the sterilizing dryer monitors whether the internal temperature of the sterilizing dryer is above the reference temperature. Since the internal humidity of the sterilizer dryer is higher than the intermediate humidity, the internal humidity of the sterilizer dryer should be rapidly lowered in order to increase the efficiency of sterilization. The internal humidity of the sterilizer dryer can be quickly lowered by increasing the internal temperature of the sterilizer dryer. Accordingly, the sterilizing dryer needs to turn on the heater 33 to quickly lower the internal humidity of the sterilizing dryer. As a result of the monitoring, if the internal temperature of the sterilizing dryer is not less than the reference temperature, the process proceeds to step 5086; otherwise, the process proceeds to step 5085.

In step 5085, if the internal temperature of the sterilizing dryer is lower than the reference temperature, the control box 37 of the sterilizing dryer keeps the fan 31 and the ultraviolet lamp 35 on and turns on the heater 33. When the internal temperature is lower than the reference temperature, the control box 37 of the sterilizing dryer turns on the heater 33 to quickly lower the internal humidity of the sterilizing dryer. Here, the fan 31 of the sterilizing dryer and the ultraviolet lamp 35 remain on.

In step 5086, the control box 37 of the sterilizing dryer controls the fan 31 and the ultraviolet lamp 35, if the internal humidity of the sterilizing dryer is lower than the intermediate humidity (for example, 8%) or the internal temperature is higher than the reference temperature, And the heater 33 is turned off. If the internal humidity of the sterilizing drier is lower than the intermediate humidity or the internal humidity is higher than the intermediate humidity for a predetermined time (for example, 1 minute), or the internal temperature is higher than the reference temperature, the fan 31 and the ultraviolet lamp The turn-on time of the heater 33 is minimized by keeping the heater 33 off while the on state of the heater 35 is maintained.

In step 5087, the control box 37 of the sterilizing dryer confirms whether the counting of the timer of sterilization drying time is completed. If the timer for the sterilization drying time is not completed, the process returns to step 5081. If the timer for the sterilization drying time is completed, the process proceeds to step 509 shown in FIG.

The control box 37 of the sterilizing dryer maintains the internal humidity of the sterilizing dryer more than the intermediate humidity for a certain period of time during the execution of the temperature and humidity operation mode so that the internal temperature of the sterilizing drier converges to the reference temperature, Repeat. During the execution of the temperature and humidity operation mode, the control box 37 of the sterilizing dryer controls the heater 33 of the sterilizing dryer only when the internal humidity of the sterilizing dryer is maintained above the intermediate humidity for a certain period of time and the internal temperature of the sterilizing dryer is lower than the reference temperature ). That is, the control box 37 of the sterilizing dryer controls the heater 33 by turning off the heater 33 of the sterilizing dryer irrespective of whether the internal humidity of the sterilizing dryer is lower than the intermediate humidity, And the energy consumption can be reduced. The temperature and humidity operation mode is performed until the counting of the timer of the sterilizing drying time is completed.

FIG. 8 is a flowchart showing in detail the continuous operation mode shown in FIG. Referring to FIG. 8, the continuous operation mode may be composed of the following steps. In step 801, the control box 37 of the sterilizing dryer turns on the heater 33, the fan 31, and the ultraviolet lamp 35. When the sterilizing dryer is operated, the control box 37 of the sterilizing dryer turns on the heater 33 of the sterilizing dryer, the fan 31 and the ultraviolet lamp 35, raises the internal temperature of the sterilizing dryer, Circulate with outside air to remove internal humidity.

In step 802, the control box 37 of the sterilizing dryer monitors whether the internal temperature of the sterilizing dryer is above a reference temperature during the warm-up of the heater 33, the fan 31 and the ultraviolet lamp 35. The control box 37 of the sterilizer dryer uses a temperature sensor 52 located inside the housing 10 to monitor whether the internal temperature of the sterilizer dryer is above a reference temperature. If the internal temperature of the sterilizing dryer is higher than the reference temperature, the process proceeds to step 803. If the internal temperature of the sterilizing dryer is lower than the reference temperature, the internal temperature of the sterilizing dryer is continuously monitored.

In step 803, while monitoring the internal temperature of the sterilizing dryer, the control box 37 of the sterilizing dryer turns off the heater 33 if the internal temperature of the sterilizing dryer is above the reference temperature. The control box 37 of the sterilizing drier turns off the heater 33 and keeps the fan 31 and the ultraviolet lamp 35 on because the internal temperature of the sterilizing dryer has reached the preset reference temperature. In addition, the sterilizing dryer starts counting the timer in the humidity operation mode.

In step 804, the control box 37 of the sterilizer dryer monitors whether the internal humidity of the sterilizer dryer is below the upper limit humidity (e.g., 20%). The control box 37 of the sterilization dryer determines whether the internal humidity of the sterilizing dryer is below the upper humidity limit while continuously monitoring the internal humidity of the sterilizing dryer. The control box 37 of the sterilizer dryer can monitor the internal humidity of the sterilizer dryer while monitoring the internal temperature as well. As a result of monitoring the internal temperature of the sterilizing dryer, the heater 33 is turned on when the internal temperature is lower than the reference temperature, and the heater 33 is turned off when the internal temperature is higher than the reference temperature. . If the internal humidity of the sterilizing dryer is less than the upper limit humidity (20%) as a result of the monitoring of the internal humidity, the process proceeds to step 805; otherwise, the process proceeds to step 806.

In step 805, the control box 37 of the sterilizing dryer checks if the internal humidity of the sterilizing dryer is below the upper humidity limit, and if the internal humidity of the sterilizing dryer is maintained below the upper humidity limit for a predetermined time (for example, one minute). If it is determined that the internal humidity of the sterilizing dryer has remained below the upper limit humidity for a predetermined period of time, the process proceeds to step 807; otherwise, the process returns to step 804.

In step 805, the control box 37 of the sterilizing dryer checks whether the timer of the humidity operation mode (for example, 30 minutes) has been counted if the internal humidity of the sterilizing dryer is higher than the upper humidity limit. The control box 37 of the sterilizing dryer lowers the internal humidity of the sterilizing dryer while repeating the on / off operation of the heater 33 according to the change of the internal temperature of the sterilizing dryer during a timer (for example, 30 minutes) . After the completion of the timer (for example, 30 minutes) of the humidity operation mode or when the internal humidity of the sterilizing dryer is lower than the upper humidity (for example, 20%), the heater 33 is turned off, , For example, 8%) or more. This embodiment minimizes the on-time of the heater 33 in this way to maximize energy efficiency. The timer of the humidity driving mode will be described in detail below. If the timer of the humidity driving mode is completed, the process proceeds to step 807. Otherwise, the process returns to step 804.

In step 807, the control box 37 of the sterilizing dryer monitors whether the internal humidity of the sterilizing dryer is below the lower humidity limit (e.g., 5%). If the internal humidity of the sterilizing dryer is lower than the lower limit humidity, the process proceeds to step 812; otherwise, the process proceeds to step 808.

In step 808, the control box 37 of the sterilizing dryer monitors whether the internal humidity of the sterilizing dryer is above a moderate humidity (e.g., 8%) if the internal humidity of the sterilizing dryer is higher than the lower humidity. If it is determined that the internal humidity of the sterilizing and drying machine is not more than the intermediate humidity, the process proceeds to step 809. Otherwise, the process proceeds to step 812.

In step 809, the control box 37 of the sterilizing dryer checks whether the internal humidity of the sterilizing dryer is maintained for a predetermined time (for example, one minute) or more if the internal humidity of the sterilizing dryer is more than the intermediate humidity . If it is determined that the internal humidity of the sterilizing and drying machine is maintained to be higher than the intermediate humidity for a predetermined period of time, the process proceeds to step 810; otherwise, the process proceeds to step 812.

If it is determined in step 810 that the internal humidity of the sterilizing dryer is higher than the intermediate humidity for a predetermined period of time, the control box 37 of the sterilizing dryer monitors whether the internal temperature of the sterilizing dryer is above the reference temperature. Since the internal humidity of the sterilizer dryer is higher than the intermediate humidity, the internal humidity of the sterilizer dryer should be rapidly lowered in order to increase the efficiency of sterilization. As described above, the internal humidity of the sterilizing dryer can rapidly lower the internal humidity as the internal temperature of the sterilizing dryer becomes high. Accordingly, the sterilizing dryer needs to turn on the heater 33 to quickly lower the internal humidity of the sterilizing dryer. If it is determined that the internal temperature of the sterilizing dryer is not lower than the reference temperature, the process proceeds to step 812. Otherwise, the process proceeds to step 811.

If the internal temperature of the sterilizing dryer is lower than the reference temperature in step 811, the control box 37 of the sterilizing dryer turns on the heater 33 and keeps the fan 31 and the ultraviolet lamp 35 on. When the internal temperature is lower than the reference temperature, the control box 37 of the sterilizing dryer turns on the heater 33 to quickly lower the internal humidity of the sterilizing dryer. Here, the fan 31 of the sterilizing dryer and the ultraviolet lamp 35 remain on.

In step 812, the control box 37 of the sterilizer drier is turned off when the internal humidity of the sterilizing dryer is lower than the intermediate humidity (for example, 8%) or the internal temperature is higher than the reference temperature, ) And the ultraviolet lamp (35).

According to a preferred embodiment, when the user operates the sterilizing dryer in the continuous operation mode, the control box 37 of the sterilizing dryer can be forcibly terminated if the sterilizing dryer is continuously operated for 4 hours. Or when the door 11 of the sterilizing dryer is opened by the user, the operation of the sterilizing dryer is automatically terminated and the fan 31, the heater 33 and the ultraviolet lamp 35 are turned off.

FIG. 9 is a graph illustrating a temperature state of the sterilizing dryer according to an embodiment of the present invention. When the user operates the sterilizing dryer by operating the control box of the sterilizing dryer, the heater 33, the fan 31 and the ultraviolet lamp 35 of the sterilizing dryer are turned on simultaneously with the operation of the sterilizing dryer. Referring to the graph shown in FIG. 9, it can be seen that the internal temperature of the sterilizing dryer continues to rise while the heater 33 is kept on. When the internal temperature of the sterilizer drier reaches the reference temperature, the sterilizer drier turns off the heater 33 and starts performing the humidity operation mode.

During the humidity operation mode, if the internal temperature of the sterilizing dryer falls below the reference temperature, the sterilizing dryer increases the internal temperature by turning on the heater 33 and turns off the heater 33 when the internal temperature becomes the reference temperature or more, Repeat the internal temperature lowering. If the humidity of the sterilizer drier falls below the lower humidity limit in the humidity operation mode, or when the timer of the humidity operation mode is completed, the sterilizer drier operates in the temperature and humidity operating mode.

During the temperature and humidity operation mode, if the internal humidity is lower than the intermediate humidity, the sterilizing dryer maintains the heater 33 off and maintains the temperature of the fan 31 lowered even if the internal temperature is lower than the reference temperature. If the internal humidity of the sterilizing dryer becomes higher than the middle humidity during various temperature and humidity operation mode, the sterilizing dryer monitors the internal temperature. If the internal temperature is lower than the reference temperature, the heater 33 is turned on again to raise the internal temperature .

As described above, the sterilizing and drying device according to an embodiment of the present invention controls the internal temperature and the internal humidity of the sterilizing dryer during the operation of the humidity operation mode in the pre-set humidity operation mode. Therefore, it is necessary to minimize the internal humidity of the sterilizing dryer before the humidity and humidity operation mode is performed. As the number of objects in the sterilizing dryer is large, there is a large amount of humidity inside the sterilizing dryer. Therefore, it is necessary to sufficiently secure the operation time of the humidity driving mode of the sterilizing dryer in order to sufficiently lower the internal humidity of the sterilizing dryer.

FIG. 10 is a view showing the flow of air circulating inside when the sterilizing dryer shown in FIG. 1 is empty, and FIG. 11 is a view showing the flow of air circulating inside the sterilizing dryer shown in FIG. Fig. 10-11, there is shown the flow of air supplied to the inside of the sterilizing dryer by the fan 31 depending on the presence or absence of the object of the sterilizing dryer. The air sucked by the fan 31 of the sterilizing dryer is supplied to the interior of the sterilizing dryer through the vertical tube 41 and the discharge opening 43. The air supplied to the inside circulates the inside of the sterilizing dryer, And is discharged to the outside through the exhaust port (42).

The flow of air exiting through the vent 42 of the sterilizing dryer is varied based on the amount of objects located inside the sterilizing dryer. As more objects are contained in the sterilizing / drying device, the air circulation inside the sterilizing / drying device is interrupted, so that the flow of air discharged to the outside of the sterilizing / drying device through the exhaust port 42 is weakened. Accordingly, the approximate amount of the object placed inside the sterilizing dryer can be calculated by measuring the flow of the air discharged through the outlet 42 of the sterilizing dryer. The control box 37 of the sterilizing dryer can adjust the counting time of the timer of the humidity operating mode of the sterilizing dryer based on the measured air flow.

12 is an enlarged top view of a sterilizing dryer in accordance with another embodiment of the present invention. 12, the sterilizing dryer according to the present embodiment further includes a propeller 56 installed in an exhaust port 42 of the sterilizing dryer and a generator 57 connected to a rotation axis of the propeller 56. As described above, the fan 31 of the sterilizing dryer sucks air from the outside of the sterilizing dryer and causes the inside humidity of the sterilizing dryer to drop by introducing air into the sterilizing dryer. The air introduced into the sterilizing and drying machine is exhausted to the outside of the sterilizing dryer through the exhaust port 42 of the sterilizing and drying machine and the flow of the air exhausted through the exhaust port 42 of the sterilizing dryer is controlled by the number of objects .

The propeller 56 is installed at the exhaust port 42 of the sterilizing dryer and rotates according to the flow of air passing through the exhaust port 42 of the sterilizing dryer. The generator 57 is connected to the rotational shaft of the propeller 56 so that its rotational axis generates electric power having a voltage magnitude proportional to the rotational speed of the propeller 56. The output voltage of the generator 57 is input to the control box 37 of the sterilizing dryer. The control box 37 sets the counting time of the timer in the humidity operation mode in inverse proportion to the magnitude of the output voltage of the generator 57. The output voltage of the generator 57 is lowered because the flow of the air discharged to the outside of the sterilizing dryer through the air outlet 42 becomes weaker as more objects are contained in the sterilizing dryer. In this case, the control box 37 sets the count time of the timer in the humidity operation mode to be long. Conversely, the smaller the number of objects in the sterilizing / drying device, the stronger the flow of air discharged to the outside of the sterilizing / drying device through the exhaust port 42 increases the output voltage of the generator 57. In this case, the control box 37 sets the count time of the timer in the humidity operation mode to be short.

The present invention has been described above with reference to preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
