As described above, in the present invention, ultraviolet LEDs that irradiate ultraviolet rays of different wavelengths are mounted on a substrate, so that various types of bacteria can be sterilized according to each wavelength, and an LED hole is formed in the substrate cover to emit ultraviolet rays through the LED hole. Since the sterilization power is directly irradiated, the sterilization power can be improved. Furthermore, since the substrate cover is made of a thin plate of epoxy or silicon, not only can the substrate cover be easily installed by lamination on one side of the substrate, but the substrate cover can also be easily installed. It can be cleaned, and it can also prevent the board cover from burning in the event of a fire.

In addition, since the drive panel turns on either the lighting LED or the ultraviolet light LED according to the detection value of the detection sensor, it is possible to prevent the ultraviolet LED from turning on when the user is detected, and since the ultraviolet LED consists of UVA and UVC ultraviolet rays, it has sterilizing power. Since ultraviolet rays of different wavelengths can be irradiated, sterilizing power can be strengthened.

In particular, since an auxiliary light-emitting LED that operates together with the UVC ultraviolet LED is provided on the side of the UVC ultraviolet LED, the operating status of the UVC ultraviolet LED can be visually identified through the auxiliary light-emitting LED, and the UVA ultraviolet LED and the UVC ultraviolet LED are illuminated.

The sterilizing power can be further improved.

Furthermore, as the UVA ultraviolet ray LED and the UVC ultraviolet ray LED of the first ultraviolet line face each other in a substantially zigzag shape with respect to the UVA ultraviolet ray LED and the UVC ultraviolet ray LED of the second ultraviolet ray line, the UVA ultraviolet rays are exposed to the UVA ultraviolet rays. UVC ultraviolet rays are irradiated on one side, but the sterilizing effect is irradiated in a way that complements each other, so the sterilizing effect can be greatly improved.

Additionally, since the sub-board is integrally coupled to the other side of the board, some devices or components for driving can be mounted on the sub-board.

In addition, at least one of the substrate and the sub-board is fixed by being inserted into the substrate fixing rail provided in the channel of the case together with the substrate cover, and the finish plate is fixed with a piece to the piece fixing part of the channel, so it can be easily assembled.

In addition, since the detection sensor consists of either a heat sensor or a motion sensor, it is possible to detect the human body in a non-contact manner.

In addition, the timer on the drive panel counts the lighting time of the lighting LED or UV LED, so the operation of the lighting LED or UV LED can be automatically controlled. The timer is reset and restarted according to the detection value of the detection sensor, so the lighting LED's operation can be controlled automatically. It is possible to delay lights out or quickly switch from ultraviolet mode to lighting mode, and when a human body is detected, the ultraviolet LED turns off and the lighting LED turns on, thereby protecting the human body from ultraviolet rays.

Moreover, since the voice guidance unit guides the mode through the speaker, the operation of the ultraviolet mode can be confirmed by sound.

In addition, since high heat can be checked through a temperature sensor, emergency situations can be guided through an alarm warning light or buzzer in the event of a fire. Temperature sensors are provided on both sides of the long board, making it easier to measure high heat according to the point of ignition. In addition, when measuring a high temperature, an emergency situation can be announced through a speaker through the voice information unit.

Hereinafter, an ultraviolet sterilizer using dual wavelengths according to an embodiment of the present invention will be described with reference to the attached drawings.

The sterilizer according to the embodiment of the present invention includes a substrate 10, a substrate cover 17, a case 20, a detection sensor 31, and a driving panel 40 to be described later, as shown in FIGS. 1 and 5. Includes.

The substrate 10 is formed to be long as shown in FIGS. 1 and 5 . As shown, the substrate 10 has at least one of a plurality of lighting LEDs 11 emitting illumination light and a plurality of ultraviolet LEDs 12 emitting ultraviolet rays for sterilization mounted on one side to be drivable along the longitudinal direction. do. As shown in FIGS. 5 and 8, the substrate 10 drives the lighting LED 11 or the ultraviolet LED 12 on one side as the driving element is integrally provided or combined on the other side. .

As shown in FIGS. 6 and 12, the substrate 10 has lighting LEDs 11 arranged in a row along the length at the center to form one line. In addition, the substrate 10 has ultraviolet LEDs 12 arranged in a row along the longitudinal direction on both sides of the lighting LED 11, as shown in FIGS. 6 and 13, so that the lighting LEDs 11 are centered around the lighting LED 11. A pair of first and second ultraviolet ray lines (L1, L2) are formed parallel to each other on both sides of (11).

The substrate 10 is composed of ultraviolet LEDs 12 that irradiate ultraviolet rays of different wavelengths, and irradiate by complexly emitting ultraviolet rays of different wavelengths. For this purpose, the substrate 10 includes an ultraviolet LED 12 consisting of a UVA ultraviolet LED 12a and a UVC ultraviolet LED 12b, which respectively irradiate long-wavelength ultraviolet rays of 315 to 400 nm and short-wavelength ultraviolet rays of 100 to 280 nm. Accordingly, the substrate 10 provides a sterilization effect similar to solar sterilization through UVA ultraviolet rays, and provides a sterilization effect for sterilizing harmful bacteria such as bacteria that were not sterilized by UVA through UVC ultraviolet rays. Therefore, since the substrate 10 is irradiated with UVA ultraviolet rays and UVC ultraviolet rays in combination, the sterilization effect is doubled.

Here, to explain the above-mentioned UVA and UVC ultraviolet rays in more detail, in the case of UVA ultraviolet rays, the wavelength is long and can reach the earth, and it is the wavelength that reacts most strongly to porphyrins present in bacteria based on the principle of porphyrin reaction decomposition. Although it helps with sterilization, it has the disadvantage of requiring a long sterilization time to be sterilized. However, it has the advantage of having a relatively low impact on the human body. In addition, UVC ultraviolet rays have a short wavelength, so they cannot reach the earth and are completely absorbed by the ozone layer, so they can be obtained from LEDs. They have strong sterilizing power, so they penetrate the outer cell membrane of viruses, bacteria, proliferating yeast, and mold, and the DNA and RNA necessary for bacterial growth. It is useful because it can sterilize Escherichia coli, Staphylococcus aureus, salmonella, pneumoniae, etc. by impacting and destroying them, but there is a problem that it is harmful to the human body when exposed for a long time, but this suppresses the growth of harmful insects such as fruit flies and cockroaches. You can do it. Due to the above-mentioned characteristics, UVC ultraviolet rays are widely used in hospitals, pharmaceutical manufacturing, water purification, agricultural product freshness maintenance devices, and air purifiers.

The length of the substrate 10 is irradiated alternately with UVA ultraviolet rays and UVC ultraviolet rays, with UVA ultraviolet LEDs 12a and UVC ultraviolet LEDs 12b alternating as shown in Figures 3 and 6. It is installed according to the direction. Accordingly, the substrate 10 is irradiated with UVA ultraviolet rays and UVC ultraviolet rays in a complex combination from each of the ultraviolet ray lines L1 and L2. That is, the substrate 10 is irradiated with dual wavelength hybrid ultraviolet rays.

In addition, as shown in FIGS. 3 and 6, the substrate 10 has UVA ultraviolet LEDs 12a and UVC ultraviolet LEDs 12b of the first ultraviolet line L1 and the second ultraviolet line L2, They are installed to face each other in the first ultraviolet ray line (L1) and the second ultraviolet ray line (L2), and as shown, they are installed in a substantially zigzag shape by facing each other in an offset state. Accordingly, the substrate 10 is provided with a UVC ultraviolet ray LED (12b) in the second ultraviolet ray line (L2) opposite to the UVA ultraviolet ray LED (12a) of the first ultraviolet ray line (L1). ) UVC ultraviolet rays are irradiated on the opposite side of the UVA ultraviolet rays emitted from ). Accordingly, the substrate 10 irradiates UVA and UVC ultraviolet rays in a complementary form from opposite sides and evenly sterilizes germs (e.g., viruses, bacteria, mold, etc.), further doubling the sterilization effect.

Since the UVC ultraviolet rays are not visible to the naked eye when the UVC ultraviolet LED 12b is turned on, the substrate 10 is provided with an auxiliary light-emitting LED ( 12c) is provided. As shown, the auxiliary light-emitting LED 12c is installed on the side of the UVC ultraviolet LED 12b and emits light while interlocking with the UVC ultraviolet LED 12b. Accordingly, the auxiliary light-emitting LED 12c guides the driving state of the UVC ultraviolet LED 12b through illumination light.

As shown in FIGS. 2 and 7, the substrate 10 is provided with a switch (SW) at one end of the other side. The substrate 10 is turned on or off according to the operation of the switch SW. Accordingly, the substrate 10 can be maintained in an off state when not in use.

As shown in FIGS. 5 and 8, the substrate 10 includes devices for driving the lighting LED 11, the ultraviolet LED 12, and the above-mentioned detection sensor 31, or an adapter (not shown) for applying power. It may further include a sub-board 15 on which at least one of the couplers (CP) for coupling the jack-type connector is mounted. As shown in FIGS. 7 and 8, the sub-substrate 10 is coupled to the other side of the substrate 10 and becomes integrated with the substrate 10. As shown in FIG. 8, the sub-board 10 is provided with a slot into which a coupling pin provided on the other side of the substrate 10 is inserted, and is firmly fixed to the lower part of the substrate 10 by the coupling pin and the slot. These coupling pins and slots may be configured to conduct electricity so that the substrate 10 and the sub-board 10 can be electrically connected. Accordingly, the substrate 10 and the sub-substrate 10 can apply power or signals to each other.

The substrate cover 17 is made of a thin plate material with a size corresponding to the substrate 10, as shown in FIGS. 5 and 6. As shown, the substrate cover 17 is laminated on one side of the substrate 10 to shield and protect one side of the substrate 10. As shown, the substrate cover 17 is provided with an LED hole 17a through which the illumination LED 11 and the ultraviolet ray LED 12 are exposed so that the illumination light and ultraviolet rays of the substrate 10 can be transmitted. The substrate cover 17 is preferably made of epoxy or silicone material so that the substrate 10 can be flame retardant and cleaned by wiping with a rag.

Case 20 is composed of a case with one side open as shown in FIGS. 1 and 9. As shown in FIGS. 1 and 5, the case 20 includes a substrate 10 and a substrate cover 17 integrally mounted thereon. At this time, the substrate cover 17 that shields one side of the substrate 10 is installed to be exposed to one open side of the case 20, as shown.

Case 20 may be composed of a channel 21 and a finishing plate 23, for example, as shown in FIGS. 9 and 10. As shown, the channel 21 has a cross-section approximately like 'ㄷ' and is composed of a profile in which a substrate fixing rail 21a and a piece fixing part 21b are provided in opposing states on both sides of the inner surface. As shown in FIGS. 10 and 11, the substrate fixing rail 21a is configured in the form of a fitting groove into which at least one of the substrate 10 and the sub-substrate 10 is inserted and fixed. As shown, the piece fixing portion 21b is configured in the form of a female thread to secure the piece P for fastening the finishing plate 23. As shown, the closing plate 23 is fixed to both ends of the channel 21 through a piece P to shield both ends of the channel 21. Accordingly, only one side of the channel 21 is open as shown.

As shown in FIGS. 1 and 9, the case 20 is provided with a through hole through which the above-described coupler CP passes through the finish plate 23 on one side. As shown in FIGS. 2 and 9, the case 20 is provided with a through hole through which the above-described switch SW passes through the finish plate 23 on the other side. Accordingly, the coupler (CP) and switch (SW) are exposed on both sides of the case 20, respectively.

As shown in FIGS. 10 and 11, the case 20 is fixed by inserting the substrate 10 and the substrate cover 17 together into the substrate fixing rail 21a. And, as shown, the case 20 is fixed with the sub-board 10 seated on the bottom surface. As shown, the case 20 is provided with an elastic body 15a on the lower surface of the sub substrate 10 to elastically support the sub substrate 10, thereby preventing the sub substrate 10 from moving. This elastic body 15a can be made of, for example, a typical foam tape attached to the lower surface of the sub-board 10. Accordingly, the sub-board 10 can be stably driven because movement is prevented by the elastic body 15a and short-circuiting is prevented.

The detection sensor 31 is mounted on the board 10 as shown in FIGS. 1 and 8 and detects a human body adjacent to the board 10. As shown, when the substrate cover 17 is stacked on the substrate 10, the detection sensor 31 is exposed through a through hole formed in the substrate cover 17. Therefore, the detection sensor 31 can smoothly detect the human body.

The detection sensor 31, for example, is composed of a sensor that detects the human body within 10 cm, and can be configured as a typical IR type motion sensor that detects the user's movement. In contrast, it can be configured as a typical PIR type motion sensor that detects the user's heat. It can also be configured with a thermal sensor. When the detection sensor 31 is configured as a motion sensor, the human body turns on the lighting LED 11 when a part of the user's body (e.g., a hand) passes by once, and turns off the lighting LED 11 when it passes again. The movement is detected and a detection signal is applied to the control unit 49, which will be described later. In contrast, when the detection sensor 31 is configured as a heat detection sensor, it detects heat emitted from the user's body to control the operation of the lighting LED 11 and applies a detection signal to the control unit 49, which will be described later.

The driving panel 40 is configured as shown in FIG. 15, and the lighting LED 11 or the ultraviolet LED 12 of the substrate 10 is based on the detection value (detection signal) of the above-described detection sensor 31. The operation is controlled to operate the lighting LED (11) or the ultraviolet LED (12). At this time, the driving panel 40 turns on only one of the lighting LED 11 or the ultraviolet ray LED 12.

The driving panel 40 may be configured to include a power source 41, a switching unit 43, a timer 44, and a control unit 49, as shown in FIG. 15, for example. The power supply unit 41 converts external power or power from a battery (not shown) into driving power for driving the board and supplies it to the board. The switching unit 43 controls the power applied to the lighting LED 11 or the ultraviolet LED 12 of the substrate 10 by switching the power of the power supply unit 41 according to the detected value of the detection sensor 31. That is, the switching unit 43 supplies or blocks power applied from the power unit 41 to the lighting LED 11 or the ultraviolet ray LED 12 of the substrate 10. The timer 44 counts the operating time of the detection sensor 31 or the lighting LED 11 or ultraviolet ray LED 12 of the substrate 10. The control unit 49 controls the operation of the lighting LED 11 or the ultraviolet LED 12 of the substrate 10 by controlling the operation of the timer 44, the switching unit 43, and the detection sensor 31 described above.

When the lighting LED 11 is turned on, the control unit 49 controls the lighting LED 11 to turn on for a lighting time of 8 to 25 seconds through the timer 44, and detects a human body from the detection sensor 31 during the lighting time. When a signal is applied, the lighting time is initialized through the timer 44 and then counted again to control the delay in turning off the lighting LED 11. In addition, when the ultraviolet LED 12 is turned on, the control unit 49 controls the ultraviolet LED 12 to turn on for a lighting time of 5 minutes to 2 hours through the timer 44, and the detection sensor 31 is activated during the lighting time. When a human body detection signal is applied from, the ultraviolet LED 12 is controlled to turn off.

For example, when the lighting times of the lighting LED 11 and the ultraviolet LED 12 are set to 10 seconds and 1 hour, the control unit 49 first supplies power to the lighting LED 11 to turn on the lighting LED 11. turns on and at the same time operates the timer 44. At this time, the timer 44 counts the preset 10 seconds and then applies a counting completion signal to the control unit 49. Accordingly, the control unit 49 determines that the lighting time of the lighting LED 11 is completed and cuts off the power applied to the lighting LED 11 to turn off the lighting LED 11. However, if a human body detection signal is applied from the detection sensor 31 before the counting of the timer 44 is completed, the control unit 49 resets the timer 44 and counts again from the beginning while turning on the lighting LED 11. is continuously supplied to delay the turning off of the lighting LED (11). That is, the control unit 49 continues to light the lighting LED 11.

In contrast, when the counting of the timer 44 is completed and the lighting LED 11 is turned off, the control unit 49 turns on the ultraviolet ray LED 12 and operates the timer 44 again. At this time, the timer 44 counts for a preset time and then applies a counting completion signal to the control unit 49. Accordingly, the control unit 49 determines that the lighting time of the ultraviolet LED 12 is completed and cuts off the power applied to the ultraviolet LED 12 to turn off the ultraviolet LED 12.

However, when a human body detection signal is applied from the detection sensor 31 before the counting of the timer 44 is completed, the control unit 49 immediately turns off the ultraviolet LED 12 and simultaneously turns on the lighting LED 11 described above. The timer 44 is activated to count the time, and at the same time, the lighting LED 11 is turned on again. Accordingly, the control unit 49 protects the user from ultraviolet rays by turning off the ultraviolet ray LED 12 when the user is detected. That is, the control unit 49 controls the lighting LED 11 to turn on while the ultraviolet ray LED 12 turns off. In conclusion, the control unit 49 turns on either the ultraviolet LED 12 or the lighting LED 11 according to the detection signal from the detection sensor 31.

Here, if the lighting time of the lighting LED 11 by the above-described timer 44 is set to less than 8 seconds, the counting time is too short and the timer 44 is operated too excessively, and if set to exceed 25 seconds, In this case, the lighting LED 11 is turned on for too long because the running time is too long, so it is preferable to set it to 10 to 25 seconds as described above. Considering the operation of the timer 44, it is more preferable to set it to about 15 seconds. , most preferably set to about 15 seconds. In addition, if the lighting time of the ultraviolet LED 12 by the timer 44 is set to less than 5 minutes, sterilization may be insufficient, and if it is set to exceed 2 hours, the sterilization time is too excessive and ineffective, so the above-mentioned As shown, it is preferable to set it to 5 minutes to 2 hours, and when considering an appropriate sterilization time, about 30 minutes is more preferable, but when considering more reliable sterilization, it is most preferable to set it to about 1 hour.

Meanwhile, the above-described driving panel 40 may be configured to further include a speaker (SP) and a voice guidance unit 45, as shown in FIG. 15. As shown in FIG. 6, the speaker SP is provided on the substrate 10 and emits sound. The voice guidance unit 45 provides voice guidance on the operation of the lighting LED 11 or the ultraviolet ray LED 12 of the substrate 10 through the speaker SP.

For example, the voice guidance unit 45 may be composed of a voice storage unit 45a and an output signal application unit 45b as shown in FIG. 16. The sound storage unit 45a stores the lighting guidance sound of the lighting LED 11 and the ultraviolet ray lighting guidance sound of the ultraviolet ray LED 12, respectively. For example, the voice storage unit 45a stores a lighting guidance voice such as “This is the lighting mode” or an ultraviolet ray lighting guidance voice such as “Sterilization is starting.”

The output signal application unit 45b transmits the voice storage unit 45a based on the switching signal of the switching unit 43 so that the guidance voice is output through the speaker SP according to the switching signal of the switching unit 43 described above. An output signal of either the stored light-on guidance voice or the ultraviolet light-on guidance voice is applied to the control unit 49. For example, when the switching unit 43 is switched to supply power to the lighting LED 11, the output signal application unit 45b outputs a lighting guidance voice output signal so that the voice guidance “This is the lighting mode” is output. Print out. In addition, when the switching unit 43 is switched to apply power to the ultraviolet LED 12, the output signal application unit 45b outputs an ultraviolet ray lighting guidance voice output signal so that the voice guidance “sterilization begins” is output. do. Accordingly, the control unit 49 applies the corresponding voice signal among the guidance voices stored in the voice storage unit 45a to the speaker SP and outputs it.

Meanwhile, the driving panel 40 may further include a temperature sensor (T), alarms (LP, BZ), and an alarm driving unit 47, as shown in FIGS. 6 and 15. The temperature sensor T is installed on the substrate 10 as shown and measures the surrounding temperature. The temperature sensor T is configured as a pair to measure the ambient temperature on both sides of the substrate 10 and is installed on both sides of the substrate 10, respectively.

Alerts (LP, BZ) warn of overheating temperature with sound or lighting depending on the temperature measured by the temperature sensor (T). Alerts (LP, BZ) can be configured, for example, with an LED warning light (LP) or a buzzer (BZ) shown in FIGS. 15 and 17 so that even visually or hearing impaired people can check the warning.

The alarm driver 47 operates the above-described alarms LP and BZ according to the temperature measured by the temperature sensor T. For example, the alert driver 47 may be composed of a comparison unit 47a and a set temperature storage unit 47b as shown in FIG. 17. The comparison unit 47a compares whether the temperature value of the temperature sensor T corresponds to a preset overheating temperature or a preset overheating release temperature, and provides a warning signal or release signal for operation of the alarms LP and BZ. It is applied to the control unit 49. The set temperature storage unit 47b stores the overheating temperature and overheating release temperature compared in the comparison unit 47a. For example, the set temperature storage unit 47b may have the overheating temperature and overheating release temperature set to 65°C and 62°C. Therefore, when a warning signal is applied from the comparison unit 47a, the control unit 49 determines that the fire is caused by overheating temperature and activates the alarms (LP, BZ), and when the release signal is applied, the fire situation is determined to have ended. The judgment is made and the operation of the alarms (LP, BZ) is stopped.

Here, the above-described voice guidance unit 45 may be configured to store an overheating warning or a guidance voice guiding overheating release. For this purpose, the voice information unit 45 stores an overheating detection guidance voice or an overheating release guidance voice and indicates by voice through the speaker (SP) whether the measured temperature of the temperature sensor (T) corresponds to the overheating temperature or whether the overheating has been released. I can guide you. At this time, the control unit 49 transmits a guidance voice such as “high temperature heat detected” or “high temperature situation has ended” stored in the voice guidance unit 45 to the speaker (SP) according to the above-described overheating signal or release signal. Print it out. Accordingly, the control unit 49 can warn or confirm the fire or the end of the fire.

Meanwhile, the case 20 includes a fixing magnet (M1) fixed to one side of the channel 21, as shown in FIGS. 18 and 19, and an attachment magnet (M2) attached by magnetic coupling to the first magnet (M1). There is a need to include more. As shown in FIG. 19, the case 20 is attached to the attachment magnet (M2) through the fixing magnet (M1) after the attachment magnet (M2) is attached to a shelf, sink, shoe cabinet, closet, etc. Accordingly, the case 20 can be easily installed as a detachable unit on a shelf or sink as shown.

As shown in FIGS. 5 and 10, the ultraviolet sterilizer using dual wavelengths according to the embodiment of the present invention configured as described above attaches the substrate 10 to the substrate fixing rail 21a formed in the channel 21 of the case 20. ) and the board cover 17 are inserted and fixed along the longitudinal direction of the case 20, and the sub-board 10 is fixed to the bottom surface of the channel 21 by elastically supporting it through the elastic body 15a. Assembly is completed by shielding both ends of the channel 21 through the rear piece P and firmly fixing the substrate 10, the sub substrate 10, and the substrate cover 17. In this sterilizer, as shown in FIG. 13, the jack-type connector of the adapter is coupled to the coupler (CP) of the sub-board 10 attached to the board 10, and the switch (SW) provided on the other side of the board 10 ) is turned ON and is driven by the control unit 49 of the driving panel 40. At this time, the detection sensor 31 applies a detection signal to the control unit 49 when a human body is detected in the surrounding area. The control unit 49 switches the power of the power unit 41 through the switching unit 43 according to the detection signal and supplies power to the lighting LED 11 to turn on the lighting LED 11 as shown in FIG. 12. , At the same time, the timer 44 is activated to count the lighting time set to 10 seconds.

If the detection signal is re-applied from the detection sensor 31 before the counting of the timer 44 is completed, the control unit 49 continuously applies power to the lighting LED 11 through the switching unit 43 to prevent the lights from being turned off. do. However, when the detection signal is not applied from the detection sensor 31 after the counting of the timer 44 is completed, the control unit 49 determines that there are no people around and turns on the lighting LED 11 through the switching unit 43. While turning off the power, power is applied to the ultraviolet LED 12 to turn on the ultraviolet LED 12 as shown in FIG. 13. That is, the control unit 49 turns on the ultraviolet LED 12.

The control unit 49 operates the timer 44 at the same time as the ultraviolet LED 12 is turned on to count the lighting time of the ultraviolet LED 12, which is set to 1 hour. When the counting of the timer 44 is completed, the control unit 49 turns off the ultraviolet ray LED 12 by cutting off the power through the switching unit 43. However, when a detection signal is applied from the detection sensor 31 during counting, the ultraviolet ray is To protect the human body, power is supplied back to the lighting LED 11 through the switching unit 43 to turn it on, and at the same time, the ultraviolet ray LED 12 is turned off by turning off the power.

When the lighting LED 11 or the ultraviolet ray LED 12 is turned on as described above, the control unit 49 operates the voice guidance unit 45 so that the user can confirm the sterilization mode by sound, saying, “It is lighting mode.” A voice such as “Sterilization begins” is output through the speaker (SP). At this time, the output signal application unit 45b of the voice guidance unit 45 sends an output signal to the control unit ( 49) to guide the voice through the speaker (SP).

Meanwhile, when the above-described control unit 49 receives a measured temperature corresponding to an overheating temperature (e.g., exceeding 64°C and above 65°C) from the temperature sensor T, it drives the alarm driver 47 to display an alert warning light ( LP) and/or buzzer (BZ). At this time, the alarm driver 47 checks whether the measured temperature of the temperature sensor T corresponds to the overheating temperature or the overheating release temperature stored in the set temperature storage unit 47b through the comparison unit 47a, and then determines whether the temperature measured by the temperature sensor T corresponds to the overheating temperature or the overheating release temperature stored in the set temperature storage unit 47b. Activate the warning light (LP) or buzzer (BZ) according to the warning signal or release signal applied in 47a).

When a warning signal due to overheating is applied from the comparison unit 47a, the control unit 49 activates the voice guidance unit 45 and outputs a voice such as “High temperature heat has been detected” through the speaker (SP). ), and after measuring the overheating temperature at the temperature sensor (T), the overheating release temperature (below 61℃ and below 62℃) is measured again and a release signal is applied through the comparison unit (47a), “The high temperature situation has ended.” A voice like " is guided to the speaker (SP). At this time, the control unit 49 reads the corresponding guidance voice stored in the voice storage unit 45a through the output signal application unit 45b of the voice guidance unit 45 and outputs it to the speaker SP.
