Referring to FIG. 11, the light source unit 1000 according to the embodiment can sterilize the inside of the container 10 by combining with the storage unit 2000. The method of sterilizing a container according to an embodiment includes the steps of combining the light source unit 1000 and the storage unit 2000, detecting the state of the light source unit 1000, and irradiating light into the storage unit. may include.

First, the light source unit 1000 can be combined with the storage unit 2000. In detail, the light source unit 1000 that emits light in the ultraviolet band may be combined with the storage unit 2000. The light source unit 1000 and the storage unit 2000 may be coupled to each other by the first coupling part 2110 and the second coupling part 112 described above. For example, the storage unit 2000 may be fastened to the light source unit 1000 while containing liquid or the like therein. Alternatively, the storage unit 2000 may be fastened to the light source unit 1000 in an empty state without accommodating anything therein. When the light source unit 1000 and the storage unit 2000 are coupled, a signal for coupling may be applied to the second circuit board 650. In detail, when the light source unit 1000 and the storage unit 2000 are completely coupled by the above-described fastening parts 112 and 2110, a signal for coupling may be applied to the second circuit board 650. Additionally, if the light source unit 1000 is not completely coupled to the storage unit 2000, power may not be applied to the light source module 500. Accordingly, it is possible to prevent ultraviolet rays emitted from the light source unit 1000 from being applied to the user.

When the second circuit board 650 receives the signal, a step of detecting the state of the light source unit 1000 may proceed. The detecting step may be a step of detecting the state of the light source unit 1000 using a sensor included in the light source unit 1000.

The detecting step may include detecting the temperature of the light source unit 1000. The light source unit 1000 includes a first sensor 810 disposed on the circuit board 502, and the first sensor 810 can detect the temperature of the light source unit 1000. In detail, the step of detecting the temperature may be a step of detecting the temperature of the circuit board 502 on which the light emitting device 501 is disposed. For example, the first sensor 810 includes an NTC-thermistor and can detect the temperature of the circuit board 502. The temperature information sensed by the first sensor 810 may be transmitted to a control unit (not shown) of the light source unit 1000. The control unit may control whether the light emitting device 501 operates based on information received from the first sensor 810. In detail, when the temperature of the circuit board 502 detected by the first sensor 810 is below the first temperature, the control unit may apply power to the light source module 500. Additionally, when the temperature of the circuit board 502 detected by the first sensor 810 exceeds the first temperature, the control unit may not apply power to the light source module 500. Here, the first temperature may be about 60°C.

Next, a step of irradiating light into the storage unit 2000 may be performed. The irradiating step may be a step of irradiating ultraviolet rays based on the information received in the sensing step. In detail, the irradiating step may be a step in which power is applied to the light emitting device 501 when the temperature of the light source unit 1000 is below the first temperature in the sensing step. That is, if the temperature of the light source unit 1000 is below the first temperature, the user can turn the light emitting device 501 on or off through the switch unit 700 in the above step. That is, when the light source unit 1000 and the storage unit 2000 are coupled and the temperature of the light source unit 1000 satisfies the first temperature or lower, the light emitting device 501 can emit light by the user. The light emitted from the light emitting device 501 may be irradiated into the interior of the storage unit 2000 through the light transmitting member 200 and the first through hole TH1. At this time, when the user operates (on) the light source module 500 through the switch unit 700, the light source module 500 may automatically stop operating after operating for a set time. Differently, the user can operate (on) the light source module 500 through the switch unit 700 and stop (off) the operation of the light source module 500 through the switch unit 700. You can.

Alternatively, if the temperature of the light source unit 1000 detected in the sensing step exceeds the first temperature, the control unit may not apply power to the light source module 500. In detail, when the light emitting device 501 is driven in a high temperature environment exceeding about 60°C, the intensity and uniformity of output may decrease. Because of this, it may not be possible to effectively sterilize harmful organisms such as bacteria, mites, and infectious diseases remaining inside the storage unit 2000. Additionally, when the light emitting device 501 is driven in a high temperature environment, reliability may be reduced.

That is, the light source unit 1000 according to the embodiment can detect the temperature of the circuit board 502 before the light source module 500 operates. In addition, in consideration of sterilizing power and reliability, the control unit of the light source unit 1000 applies power to the light source module 500 when the temperature of the circuit board 502 is below the first temperature so that the light emitting element 501 emits light. can do. Accordingly, the light source module 500 can have improved reliability and can effectively sterilize harmful organisms remaining in the container 10 with uniform output.

Additionally, the detecting step may further include detecting a tilt or movement of the light source unit 1000. In detail, the light source unit 1000 includes a second sensor 820, and the second sensor 820 can detect the tilt or movement of the light source unit 1000. For example, the second sensor 820 may include at least one of an acceleration sensor and a gyro sensor, and may detect the tilt or movement of the light source unit 1000. The second sensor 820 may transmit the detected tilt or movement information of the light source unit 1000 to the control unit. The control unit may control whether the light emitting device 501 operates based on information received from the second sensor 820. In detail, when the tilt of the light source unit 1000 detected by the second sensor 820 satisfies a set range or there is no movement of the light source unit 1000, the control unit turns on power to the light source module 500. It can be approved. In contrast, if the tilt of the light source unit 1000 detected by the second sensor 820 exceeds the set range or movement is detected, the control unit will not apply power to the light source module 500. You can. Here, the inclination may mean the angle between the optical axis of the light emitting device 501 and the ground surface, and the inclination in the set range may be about 80 to 100 degrees.

Next, a step of irradiating light into the storage unit 2000 may be performed. The irradiating step may be a step of irradiating ultraviolet rays based on information received in the sensing step, for example, information received from the first sensor 810 and the second sensor 820. In detail, the irradiating step is performed when the temperature of the circuit board 502 detected by the first sensor 810 is below the first temperature and the light source unit 1000 does not move or tilt, the light emitting device This may be the step in which power is applied to (501). That is, when the temperature of the light source unit 1000 satisfies the first temperature or less, the light source unit 1000 does not move, and the slope of the set range described above is satisfied, the light source module ( Power may be applied to 500). Additionally, the light source unit 1000 can operate when fastened to the storage unit 2000 and positioned in the forward direction. Here, being in the forward direction may mean that the storage unit 2000 is located at the bottom based on the direction of gravity and the light source unit 1000 is disposed and fastened above the storage unit 2000. In other words, this may mean that the container is not turned over. That is, in the embodiment, when the container 10 is placed in the above-mentioned forward direction and satisfies the inclination of the set range, the user turns the light emitting device 501 on or off through the switch unit 700. (OFF) You can.

Alternatively, in the sensing step, if the temperature of the circuit board 502 is below the set temperature, but the light source unit 1000 moves or is tilted at an angle exceeding the set range, the light source module 500 is not powered. This may not be approved. That is, when a user moves while carrying the light source unit 1000 or the container 10 containing the same, power is not applied to the light source module 500 and the light emitting element 501 may not emit light. In addition, when the light source unit 1000 or the container 10 containing it is in the reverse direction opposite to the forward direction or is tilted at an angle exceeding a set range, power is not applied to the light source module 500 and the light is emitted. The element 501 may not emit light.

That is, the container 10 according to the embodiment may have improved heat and cold insulation characteristics by the heat insulating member 400 disposed within the light source unit 1000. Additionally, if the light source unit 1000 is not fastened to the storage unit 2000, power may not be applied to the light source module 500. Additionally, the light source unit 1000 can control the operation of the light emitting device 501 by detecting temperature, tilt, movement, etc. Accordingly, exposure of ultraviolet rays to the user can be double prevented, and the interior of the container 10 can be effectively sterilized with improved reliability and uniform sterilizing power.
