1 is a conceptual diagram of an electric sterilizer 100 according to some embodiments of the present invention.

Referring to FIG. 1, there is a space in which an object to be sterilized including a sterilization and drying operation is located in the body of the electric sterilizer 100, and objects such as a baby bottle, cup, toothbrush, and bowl are the electric sterilizer 100 ) Can be placed through a variety of means, such as a holder separately provided inside the main body of a), a shelf (above, not shown). In addition, a plurality of devices for performing a disinfection function may be disposed inside the electric sterilizer 100, and as an example, a plurality of ultraviolet irradiators may be disposed inside the electric sterilizer 100. As an example, in FIG. 1, two side ultraviolet irradiators 151 and 152, two upper ultraviolet irradiators 161 and 162, and a lower ultraviolet irradiator 170 are illustrated. The upper ultraviolet irradiators 161 and 162 may be installed on an upper wall of the electric sterilizer 100, and the lower ultraviolet irradiator 170 may be installed on the floor of the electric sterilizer 100.

According to an embodiment, the ultraviolet irradiators may be implemented through various ultraviolet irradiation means. In example embodiments, the ultraviolet irradiators may include at least one of an ultraviolet lamp and an ultraviolet light emitting device (UV LED). According to a preferred embodiment, the side ultraviolet irradiators 151 and 152 and the upper ultraviolet irradiators 161 and 162 may include an ultraviolet lamp, and the lower ultraviolet irradiator 170 is an ultraviolet light emitting device (UV LED). ) Can be included. 1 shows an example in which two ultraviolet irradiators are located on the side and upper sides of the electric sterilizer 100, respectively, and one ultraviolet irradiator is located at the lower side of the electric sterilizer 100, but various numbers are provided on the side, upper and lower sides of the electric sterilizer 100, respectively. It would be okay to have an ultraviolet irradiator located.

The door of the electric sterilizer 100 is arranged to open and close the interior of the main body, and the door may be configured to close the entrance while the sterilization and drying operation is in progress on the object, and to carry in and out the object It can be configured to open the doorway. In addition, the object in the electric sterilizer 100 may be sterilized by ultraviolet rays irradiated by the aforementioned plurality of ultraviolet irradiators. In exemplary embodiments, the above-described ultraviolet irradiators may be configured to emit ultraviolet rays in a wavelength band suitable for sterilization, for example, a UV wavelength band. Although not shown in FIG. 1, the electric sterilizer 100 may further include an electric heater such as a PTC (Positive Temperature Coefficient) heater as a drying module (not shown) in order to provide a function of drying an object. The drying function for the object may be performed based on the air heating by the air and the air circulation operation through the suction fan (not shown).

Meanwhile, the electric sterilizer 100 may include a microcomputer 110 for performing an overall control operation and a door detection sensor 120 for detecting opening and closing of the door. The micom 110 may perform an electrical and/or mechanical control operation on various components provided in the electric sterilizer 100, and as an example, a safe storage function (or , Automatic drying function) can be performed a series of operations to control. In addition, the door detection sensor 120 may detect whether the door of the electric sterilizer 100 is opened or closed, and may provide a detection result to the microcomputer 110. The above-described safe storage function may be controlled by the microcomputer 110 using the detection result from the door detection sensor 120.

On the other hand, according to an embodiment, a rotating table 130 in which rotation is controlled by a predetermined motor (not shown) is disposed inside the main body of the electric sterilizer 100, and the holder column 140 is on the rotating table 130. As it is placed on, when the rotation table 130 is rotated, the cradle column 140 may also be rotated together. Accordingly, objects mounted on the cradle column 140 may be rotated inside the body while sterilization and drying operations are performed. In addition, the electric sterilizer 100 may further include a humidity sensor 180, and the humidity sensor 180 may be disposed at any position inside the electric sterilizer 100, and the humidity sensor 180 senses humidity. The result is provided to the micom 110, and the micom 110 may further use the humidity detection result to control the operation according to the safe storage function.

The electric sterilizer 100 can perform normal sterilization and drying functions according to the user's selection, and after the normal sterilization and drying functions are completed, the user can store and use the object inside the main body of the electric sterilizer 100. have. At this time, the door of the electric sterilizer 100 may be frequently opened and closed in order to take out or put the object, and the humidity inside the body increases depending on the external environment. In particular, when the external environment corresponds to a high humidity season or weather, external moisture quickly enters the body, which increases the humidity inside the body, and bacteria in the air flow into the body, causing bacteria from inside the body. Can be easily reproduced.

According to an exemplary embodiment of the present invention, the electric sterilizer 100 may operate in a safe storage mode, and when the object is stored in the electric sterilizer 100 after performing normal sterilization and drying functions, the electric sterilizer 100 It can be determined whether the door of the door is open or not, and when it detects that the door is open, it performs an automatic drying function (or automatic sterilization and drying function) irrespective of the user's selection. Can be suppressed. As an example of operation, the electric sterilizer 100 may determine whether the humidity inside the body is increased by continuously or periodically determining the humidity inside the body, or by performing a humidity detection operation after it is determined that the door is open, When the sensed humidity exceeds a predetermined reference value, the above-described automatic drying function may be performed.

According to the above operation example, even if the user puts the object in the main body after performing the normal sterilization and drying function, even if the humidity inside the main body increases according to the opening and closing state of the door, the object is safely stored through the automatic drying function. Can be stored. In addition, in the above-described example, it has been described that the drying operation inside the body is performed in the safe storage mode, but similar to the normal sterilization and drying functions, the safe storage function may also include a sterilization and drying function.

On the other hand, in the embodiments to be described later, examples in which various operations according to the safe storage function and operations according to the normal sterilization and drying functions are performed according to different methods through different determination criteria will be described. The sterilization and drying operation may be performed substantially the same as the normal sterilization and drying operation. In addition, in some embodiments, for convenience of explanation, only the drying operation may be described in relation to the safe storage function, but as described above, the sterilization operation may be further performed together with the drying operation in the safe storage function.

2 is a flowchart showing a method of operating an electric sterilizer according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the power of the electric sterilizer is turned on (S11), and a normal sterilization and drying function for an object may be performed according to a user's selection (S12). In addition, even after the normal sterilization and drying functions are completed, the object may be stored inside the main body.

The humidity inside the main body of the electric sterilizer may increase due to reasons such as the user does not close the door of the electric sterilizer after opening it, and the electric sterilizer may generate a result of detecting the door opening through the door detection operation (S13). In addition, by detecting the door opening, it may be determined whether the safe storage function of the electric sterilizer is currently selected (S14), and when the safe storage function is selected, the humidity inside the sterilizer body is adjusted in response to the detection of the door opening. The sensing operation may be performed (S15).

For safe storage of the object, a reference value of humidity inside the body is set, and it may be determined whether the sensed humidity exceeds the reference value (S16). If the detected humidity does not exceed the reference value, the automatic drying operation is not performed, but when the detected humidity exceeds the reference value, the automatic drying operation may be performed (S17). In addition, even if the detected humidity does not exceed the reference value, the door of the electric sterilizer may be opened again afterwards, thereby further increasing the humidity inside the main body. Accordingly, as the operation of detecting the humidity is continuously or periodically performed, the main body When the internal humidity exceeds the reference value, the automatic drying function according to the embodiment of the present invention may be performed. As an example of the operation, when the opening of the door of the electric sterilizer is detected, the humidity detection and comparison operation may be periodically performed even if the humidity inside the body does not exceed a reference value. Alternatively, if the opening of the door of the electric sterilizer is detected and the humidity inside the body does not exceed the reference value, the determination operation for automatic drying is terminated, and the above automatic drying is performed when the door opening is detected again. A determination operation for may be performed.

Meanwhile, in the above-described embodiment, it has been described that the humidity detection operation for the automatic drying function is selectively performed based on the result of detecting the opening of the door, but the embodiment of the present invention need not be limited thereto. As an example, regardless of the opening and closing of the door, the humidity inside the body can be detected continuously or periodically, and when the humidity inside the body exceeds the reference value, the automatic drying function described above regardless of whether the door is opened or not. This could be done.

3 is a graph showing an example of a change in humidity inside the main body of the electric sterilizer of the present invention.

Referring to FIG. 3, as normal sterilization and drying functions are performed, the humidity inside the body may be lowered, and as an example, the humidity inside the body may be reduced to a very small value according to a user's selection and a predetermined set method. Thereafter, as the door of the electric sterilizer is opened, the interior of the body is exposed to outside air, and thus, the humidity inside the body may gradually increase. If the safe storage function according to the embodiment of the present invention is not applied, the humidity inside the body is maintained at a high value.

On the other hand, as the safe storage function according to the embodiment of the present invention is applied, the automatic drying function is performed regardless of the user's selection at a specific point in time, and accordingly, the humidity inside the body may be lowered to a predetermined set humidity. As an example, in response to detecting the opening of the door of the electric sterilizer, a humidity sensing operation inside the main body may be performed, as an example, a humidity sensing operation is performed while the door is open, or humidity is detected after the door is closed again. The operation can be performed. In addition, when the humidity detection result is compared with a predetermined reference value, and when the humidity inside the body exceeds the reference value, the automatic drying function may be performed, and in FIG. 3, the set humidity according to the automatic drying function is normal sterilization and drying. The same example as the humidity after performing the function is shown, but the set humidity according to the automatic drying function may be set to various values.

4 is a block diagram showing an exemplary embodiment of the electric sterilizer of the present invention.

Referring to FIG. 4, the electric sterilizer 200 may include a plurality of ultraviolet irradiators (eg, UV lamps, UV LEDs 261 and 262), and supply power to the ultraviolet irradiators 261 and 262 It may further include a lamp driver 251 and an LED driver 252 for providing. In addition, the electric sterilizer 200 may further include an object detection sensor 230 and the above-described humidity sensor 240 for detecting objects mounted inside the electric sterilizer 200 to perform disinfection. 210) and a door detection sensor 220 may be further included. In addition, the electric sterilizer 200 may further include a drying module 270 that lowers the humidity inside the body by performing a drying operation.

The object detection sensor 230 may detect whether one or more objects are present in the electric sterilizer 200, and may provide a result of detecting the object to the microcomputer 210. As an example, the object detection sensor 230 may detect objects through various methods, and according to an embodiment, the object detection sensor 230 is positioned on each of a plurality of cradles, so that the object is mounted on the corresponding cradle. It is possible to detect whether or not to generate the detection result. In addition, the humidity sensor 240 may output a humidity detection result by sensing humidity in the electric sterilizer 200, and the humidity sensor 240 may operate according to various driving conditions. As an example, the humidity sensor 240 may perform a humidity detection operation periodically or continuously even after the normal sterilization and drying functions are completed, or humidity detection based on a result of detecting the opening of the door of the electric sterilizer 200 You can perform the operation. Alternatively, the humidity sensor 240 may perform a humidity detection operation based on a combination of a result of detecting the opening of the door and a result of detecting the presence of an object inside the body.

The micom 210 may include an automatic drying determination module 211, and the automatic drying determination module 211 performs various determination operations for performing the automatic drying operation according to the above-described embodiment as the safe storage function is applied. Can be done. As an example, the automatic drying determination module 211 may include reference information including various reference values and set values, and an automatic drying operation through a detection result from various sensors and a processing operation using the above reference information It can be determined whether or not to perform.

As an example of operation, the automatic drying determination module 211 may compare a humidity detection result provided from the humidity sensor 240 with one or more reference values according to a result of detecting the door opening from the door detection sensor 220. As an example, as the door of the electric sterilizer 200 is opened, the humidity inside the body gradually increases, and as the humidity detection result exceeds a reference value, the automatic drying determination module 211 determines the timing to perform the automatic drying operation. I can judge.

In addition, the automatic drying determination module 211 may determine whether an object exists in the body according to the detection result from the object detection sensor 230, and perform an automatic drying operation when the object exists inside the body. It can be judged as. The micom 210 can control the automatic drying operation by outputting various control signals (Ctrl) based on the determination result from the automatic drying determination module 211. As an example, the micom 210 is a drying module 270 By driving, it is possible to perform the above-described automatic drying function. In addition, in the safe storage function, the sterilization operation may be further performed together with the automatic drying operation, and the micom 210 is the UV lamp 261 and the UV LED 262 through the lamp driver 251 and the LED driver 252. You can control the drive. In addition, although not shown in FIG. 4, a rotary table (not shown) in which rotation is controlled by a motor is further provided inside the main body of the electric sterilizer 200, and sterilization and drying operations in the safe storage function as the rotary table rotates. During this operation, the objects can be rotated inside the body.

According to the embodiment shown in FIG. 4, the automatic drying determination module 211 determines whether or not the safe storage function is applied, and an automatic drying operation through a processing operation using detection results from various sensors and reference information. Whether or not to perform can be finally determined. For example, in the case of objects on which normal sterilization and drying operations have been performed, since they have already been sterilized, automatic drying operations on the objects need not be performed frequently unnecessarily, and whether to perform automatic drying operations accordingly. The operation of determining is may be optimized using the above-described various detection results and reference information. In addition, in the case of the normal sterilization and drying function, compared to the case where it is performed for a preset time according to the user's selection, in the case of the automatic drying operation, only the amount of time required to lower the humidity inside the body below the set humidity based on the detected humidity It may take, and the object can be safely stored through a relatively short internal treatment.

5 is a graph showing various examples of setting the humidity inside the body of the electric sterilizer.

Referring to FIG. 5, as normal sterilization and drying functions are performed, the humidity inside the body may be reduced to a very small value. Thereafter, the opening of the door of the electric sterilizer is sensed, and it may be determined whether to perform the automatic drying function according to the humidity sensed inside the main body immediately after the door is opened or after a predetermined time. As an example of the operation, a comparison operation using a humidity detection result may be performed after a predetermined time after the door is opened, or a comparison operation using the humidity detection result may be performed after the door is closed. Alternatively, as a possible embodiment, the humidity inside the body is continuously or periodically detected, and the operation of determining whether to perform the automatic drying function using the detected humidity is based on the result of detecting the opening of the door. It may be selectively performed accordingly.

The sensed humidity is compared with a reference humidity α corresponding to a predetermined reference value, and when the detected humidity exceeds the reference humidity α, the automatic drying function in the above-described embodiments may be performed. Accordingly, the humidity inside the main body of the electric sterilizer gradually increases and then decreases again as the automatic drying function is performed, and the humidity inside the main body decreases to a level corresponding to a predetermined set humidity β. At this time, in the normal sterilization and drying operation, it is performed for a predetermined time according to the user's selection, whereas in the automatic drying operation according to the safe storage function, the humidity inside the body is continuously compared with the predetermined set humidity (β). , When the humidity detection result falls below the set humidity (β), the automatic drying operation may be terminated.

6 is a flowchart showing a method of operating an electric sterilizer according to deformable exemplary embodiments.

Referring to FIG. 6, the electric sterilizer may perform normal sterilization and drying functions for objects according to a user's selection (S21), and whether the door of the electric sterilizer is opened may be continuously detected (S22). As the door is determined to be open, the humidity inside the body may be detected (S23), and if the door is open, the humidity inside the body may continue to increase, so the closing of the door is detected according to an example of operation. When the door is closed, a constant humidity inside the main body can be detected.

According to the above-described embodiments, the sensed humidity is compared with a reference value (S24), and when the sensed humidity exceeds the reference value, an automatic drying function may be performed (S25). Also, while the automatic drying function is being performed, humidity is periodically or continuously detected, and it may be determined whether the sensed humidity falls below a set humidity (S26). In addition, when the humidity falls below the set humidity, the automatic drying function may be terminated (S27).

According to the above-described embodiment, the operation of detecting humidity and determining it in response to whether the door of the electric sterilizer is opened may be selectively performed, and the detection and determination operation may be performed after detecting the door is closed. have. Accordingly, after external moisture flows into the body while the door is open, the humidity inside the body may be appropriately determined while the door is closed, and an automatic drying function may be selectively performed based on this.

Meanwhile, a control operation for performing an automatic drying function may be performed as the door opening is detected. When the humidity detected in the door closed state is less than a reference value, the control operation related to the automatic drying function is terminated. I can. That is, in response to determining that the sensed humidity is less than or equal to the reference value, an operation of detecting the humidity inside the body and comparing it with the reference value may be terminated. Thereafter, when it is detected that the door of the electric sterilizer is opened again, the control operation to perform the automatic drying function is performed again, and accordingly, the automatic drying function is based on the result of detecting the humidity inside the body and the result of comparing it with the reference value. Whether or not to perform may be determined again.

Meanwhile, although not described in the above-described embodiments, when the automatic drying operation is performed, a notification operation indicating this may be performed in various ways. That is, since the automatic drying operation according to the safe storage function according to the embodiments of the present invention can be performed regardless of the user's selection, the automatic drying operation is notified through the display provided in the electric sterilizer, or It may be notified that the automatic drying operation is being performed through the means for generating and outputting the.

7 is a flowchart showing a method of operating an electric sterilizer according to another deformable exemplary embodiment of the present invention.

Referring to FIG. 7, it may be determined whether the sterilization and drying function is to be performed (S31), and the sterilization and drying function may be determined by various methods such as selection of a user and self-determination of the electric sterilizer. I can. When the sterilization and drying function is performed, it is determined whether the function is performed in the safe storage function mode (S32), and when it is determined that the function is performed in the safe storage function mode, when the drying function is performed, Whether the humidity falls below a predetermined set humidity may be continuously or periodically detected (S33). Also, when the sensed humidity falls below the set humidity, the sterilization and drying functions may be terminated.

On the other hand, if it is determined that the sterilization and drying function is not performed in the safe storage function mode (or it is determined that it is a normal sterilization and drying function), the sterilization and drying function is performed according to a preset method in the electric sterilizer. For example, the drying function may be performed for a predetermined set time (S34). As an example, the humidity inside the body according to the normal sterilization and drying function and the set humidity in the safe storage function mode may be set differently.

On the other hand, in the present embodiment, it has been described that the sterilization operation is further performed in the safe storage function, and as an example, external moisture may be introduced into the body to have a state in which bacteria in the air have already multiplied. It may be appropriate to be done. As an example, whether to perform the sterilization operation may be determined based on information such as a duration of the door opening, a degree of humidity inside the body, and a time elapsed since the door is opened. If the door is kept open for a long time and the internal humidity is relatively high, it is highly likely that the bacteria are propagated, and in this case, the sterilization operation is performed prior to the drying operation according to the safe storage function. I will be able to.

In addition, when the power of the electric sterilizer is turned off, whether or not the door is open may not be detected, and in this case, there is a high possibility that the door has been opened and the object is present inside for a long time. In addition, in this case, even when the humidity inside the body is not detected as high humidity outside the body, it may correspond to a state in which the object is exposed to bacteria. According to an embodiment, the electric sterilizer detects a case in which the power is turned off, and if it is determined that the power is turned off, the electric sterilizer may perform the above-described automatic drying function regardless of whether a door is opened or a humidity inside the body. Alternatively, if it is determined that the power has been turned off, the above-described automatic drying function may be performed based on the humidity detection result regardless of whether the door is opened. Alternatively, if it is determined that the power has been turned off, a sterilization operation may be further performed together with an automatic drying function.
