Next, the disconnection determining step S110 is a step of determining whether the heating wire 112 or the fuse 118 in the heat storage steamer 110 is disconnected by the microprocessor 123.

At this time, when the disconnection is determined in the disconnection determination step (S110), a current flows through the heating limit / fuse disconnection control signal output from the microprocessor 123 through the current limiting resistor R4 to light the seventh light emitting diode LED7. To indicate that the heating wire 112 or the fuse 118 is disconnected, and the operation ends.

However, if the disconnection is not disconnected in the disconnection discrimination step S110, the process proceeds to the next internal temperature discrimination step S120. The internal temperature determination step (S120) is a step of determining whether the temperature in the heat storage steamer 110 is higher than a preset overheat prevention temperature when the disconnection determination step (S110) is not a disconnection.

When the temperature in the heat storage steamer 110 is greater than the overheat prevention temperature in the internal temperature discriminating step S120, a control signal output from the microprocessor 123 is the eighth light emitting diode LED8 through the current limiting resistor R5. By turning on) to indicate that the temperature in the heat storage steamer 110 is equal to or higher than the overheating prevention temperature, and ends the operation to prevent overheating. The heat storage steamer 110 of the user is above the overheating prevention temperature, that is, it is possible to use the steaming temperature and removes the temperature control device 120 while carrying and steaming while the temperature is lowered below the overheating prevention temperature will be able to reheat. .

This temperature control method is to improve the problem of the safety accident of the conventional heat storage steamer. Even though the temperature of the heat storage steam machine is sufficient temperature for steaming, overheating or re-heating occurs when the power is re-heated due to user's carelessness or error. 116 is controlled by the temperature control device 120 to block the fatal problems such as a fire due to the malfunction of the source.

Next, the time setting switch on judging step (S130) is the time setting switch 124 is turned on (ON) when the temperature in the heat storage steamer 110 is less than the overheating temperature in the internal temperature judging step (S120). Step of determining.

Next, when the time setting switch 124 is determined to be ON in the time setting switch on judging step S130, the acceleration / deceleration time determining step S140 may be performed according to the internal temperature detected in the internal temperature judging step S120. As a step of determining a preset acceleration / deceleration time, referring to FIG. 6, which is an exemplary table showing a specific time setting for temperature control of the present invention, the internal temperature detected by the temperature detection sensor 117 in the internal temperature discrimination step S120. In accordance with the results of the experiment as shown in FIG. 6 is a step of determining the predetermined acceleration and deceleration in the microprocessor 123.

Next, when the time setting switch 124 is determined to be ON in the time setting switch on judging step S130, the pressing counting one time judging step S150 is stored by pressing the time setting switch 124 once. It is a step of determining whether the push count stored in the unit 128 is one time. The storage unit 128 is connected to the microprocessor 123, and stores a value obtained by adding a push count once each time the time setting switch 124 is pressed, and is initialized to 0 in an initialization step (S100). .

Next, when the M-minute power supply step (S160) is determined that the push count is one time in the push count one determination step (S150) (when the user's desired heating time is 'M minutes'), the heat storage As the power application signal for supplying power to the steamer 110 for M minutes + acceleration time is output from the microprocessor 123 to the first relay LY1, the first relay LY1 is excited to enable the first movable contact. (a) is brought into contact with the first fixed contact (b) to flow a current in the heating wire 112 through the bimetal 116 and is filled in the heat storage steamer 110 by heat radiated from the heating wire 112. Heating the ceramic heating wire housing 113 and the ceramic insulator 115 to accumulate M for a + min. Deceleration time, and limit the power application signal output from the microprocessor 123 in the current limiting resistor R1. First and second light emitting diodes (LED1, LED2) To flow to the first and second light emission by the light emitting diodes (LED1, LED2) is the step of indicating that power is supplied and the heat storage jjimjilgi 110.

Next, the heating wire power cut-off step (S170) is a power-on signal to the first relay (LY1) in the microprocessor 123 after the power is applied for M minutes + acceleration time in the M-minute power supply step (S160) It stops the power supply to the heating wire 112 by stopping the output of the eighth light-emitting diode (LED8) to turn on the standby LED to inform the user that the heat storage steamer 110 has become the desired steaming temperature. The user may use the steam pack for a long time while separating and carrying the heat storage steamer 110 from the temperature control device 120.

On the other hand, if it is determined that the push count stored in the storage unit 128 is not one time, as a result of the determination of the push count one determination step (S150), two push counts for determining whether the push count is two times or not Determining step S180; When it is determined that the push count stored in the storage unit 128 is two times in the press counting twice determination step (S180) (when the user's desired heating time is 'M + 1 minute'), the heat storage steamer 110 ) Is supplied to the second relay LY2 from the microprocessor 123 as the power-up signal for accumulating M + 1 minute + ramp time for the second relay LY2 is excited and the second movable contact c. A ceramic heating wire filled in the heat storage steamer 110 by heat radiated from the heating wire 112 by causing a current to flow in the heating wire 112 through the bimetal 116 by contacting the second fixed contact d. The housing 113 and the ceramic insulation 115 are heated to thermally accumulate for M + 1 minute + acceleration time, and at the same time, the current which is the heat storage control signal output from the microprocessor 123 is limited by the current limiting resistor R2. To the third and fourth light emitting diodes LED3 and LED4. M + 1 minute power supply step (S190) of emitting the third and fourth light emitting diodes (LED3, LED4) to indicate that the heat storage steamer (110) is being thermally stored; If it is determined that the push count is not two times in the push count twice determination step (S180), the push count three times determination step (S200) for determining whether the push count is three times; When it is determined that the push count stored in the storage unit 128 is three times in the press counting three times determination step (S200) (when the user's desired heating time is 'M + 2 minutes'), the heat storage steamer 110 ) Is supplied to the third relay LY3 from the microprocessor 123 as the power-up signal for accumulating M + for 2 minutes + acceleration / deceleration time is excited by the third relay LY3 to generate a third movable contact e. Is filled in the heat storage steamer 110 by heat radiated from the heating wire 112 by causing a current to flow through the bimetal 116 to the heating wire 112 by contacting the third fixed contact f. The heating wire housing 113 and the ceramic insulation 115 are heated to thermally accumulate for M + 2 minutes + acceleration time, and at the same time, the current, which is a heat storage control signal output from the microprocessor 123, is limited by the current limiting resistor R 3. Flow through the fifth and sixth light emitting diodes (LED5, LED6) An M + 2 power supply step (S210) for emitting the fifth and sixth light emitting diodes (LED5, LED6) to indicate that the heat storage steamer (110) is being thermally stored; If it is determined that the push count is not three times in the press counting three times determination step (S200), the press count is determined to be four or more times, subtracting 3 from the push count, and returning to the press counting once determination step (S150). Press count regression step (S220); through the heating time of the heat storage steamer 110 to select the 'M minutes', 'M + 1 minute', 'M + 2 minutes' by the temperature of the heat storage steamer 110 Can be adjusted according to the user's taste.

In addition, the temperature control method of the temperature control device 120 of the present invention, in addition to selecting the heating time 'M minutes', 'M + 1 minute', 'M + 2 minutes' and the temperature setting switch 125 and Accordingly, the second, fourth, and sixth light emitting diodes (LED2, LED4, LED6) are provided to allow the user to select a temperature according to the user's taste as 'weak', 'medium', or 'strong'.

However, it should be noted that this is only a convenience specification for the user's understanding, and the user's desired poultice temperature is not a temperature control method using a built-in temperature sensor. When the heat storage steamer 110 reaches the temperature desired by the user, the temperature sensor is detected by the temperature sensor based on the experimental data of the inventors' long-term experiments, not the method of measuring the temperature sensor and controlling the power supply. By regulating the time of applying power to the heat storage steamer 110 according to the current internal temperature of the heat storage steamer 110, the data is preset to 'M minute', 'M + 1 minute', 'M + 2 minute'. To control the temperature. The 'M minutes', 'M + 1 minute', 'M + 2 minutes' and 'weak', 'medium', 'strong' work the same concept and the user has a concept of temperature rather than the concept of time It is added in duplicate so that it is easy to understand.

Accordingly, the control method by the time setting switch 124 is as follows.

If it is determined that the time setting switch 124 is not ON in the time setting switch on judging step S130, the temperature setting switch on judging step S230 for determining whether the temperature setting switch 125 is on is further performed. When the temperature setting switch 125 is determined to be ON in the temperature setting switch on discrimination step (S230), the control unit moves to a push count once discrimination step (S150), and the push count of the time setting switch 124 is included. Is the same as when the case is once.

Hereinafter, a method of operating a temperature control device of a portable heat storage steamer which is an embodiment to which the present invention configured as described above is applied will be described.

First, the heat storage steamer 110 is connected to the connection terminal 114a by a connector 126a provided at the tip of the cable 126 of the temperature control device 120, and the lead wire 127 of the heat storage steamer 110 is connected. When the power switch 121 is turned on after connecting the plug 127a disposed in the AC power source (not shown), the full-wave rectifying means 122 performs full-wave rectification of the AC power source to the DC power source to provide the microprocessor ( The operating power is supplied to 123, and thus the temperature in the heat storage steamer 110 is detected by the temperature detection sensor 117 disposed in the heat storage steamer 110 and output to the microprocessor 123.

At this time, when the time setting switch 124 or the temperature setting switch 125 is pressed once, a pressing count is stored in the storage unit 128 once, and the temperature in the heat storage steamer 110 is controlled by the microprocessor 123. Determines whether the temperature is equal to or higher than the overheat prevention temperature, and determines the acceleration / deceleration time in the microprocessor 123 according to the preset chart shown in FIG. 6 according to the temperature in the heat storage steamer 110 detected when the temperature is not higher than the overheat prevention temperature. In addition, the microprocessor 123 outputs a power applying signal for supplying power to the first heat storage steamer 110 for M minutes + deceleration time according to the push count.

Next, the first relay LY1 is excited to bring the first movable contact a into contact with the first fixed contact b so that a current flows in the heating wire 112 through the bimetal 116 to heat the heating wire ( The heat dissipation heat from the 112 heats the ceramic heating wire housing 113 and the ceramic insulator 115, which is filled in the heat storage steamer 110 and heated for M minutes + deceleration time, at the same time, in the microprocessor 123 The power supply signal output according to the push count is limited by the current limiting resistor R1 to flow to the first and second light emitting diodes LED1 and LED2, thereby emitting the first and second light emitting diodes LED1 and LED2. It indicates that the heat storage steamer 110 is being heated.

In this manner, when the power-on time is heated by the heat storage steamer 110 and the M-min + deceleration time elapses, the microprocessor 123 does not output a power-on signal to the first relay LY1. Since the relay LY1 is not excited and the first movable contact a is separated from the first fixed contact b, no current flows in the heating wire 112 through the bimetal 116, so that the heat storage steamer 110 Overheating and resulting fire can be prevented.

On the other hand, when the time setting switch 124 or the temperature setting switch 125 is pressed twice while the power switch 121 is turned on, the storage unit 128 stores the push count twice, The microprocessor 123 determines whether the temperature in the heat storage steamer 110 is equal to or greater than the overheating prevention temperature, and when the temperature is not greater than the overheating prevention temperature, the second relay LY2 according to the push count of the microprocessor 123. Outputs a power application signal for heating the heat storage steamer 110 for M + 1 minute + acceleration and deceleration time.

Next, the second relay LY2 is excited to bring the second movable contact c into contact with the second fixed contact d so that a current flows in the heating wire 112 through the bimetal 116 to heat the heating wire ( The heat dissipation heat from the 112 heats the ceramic heating wire housing 113 and the ceramic insulator 115, which is filled in the heat storage steamer 110, and heat storage for M + 1 minute + acceleration time, and at the same time, the microprocessor 123 In this case, the current applied as the power supply signal at the pressing count is limited by the current limiting resistor R2 to flow to the third and fourth light emitting diodes LED3 and LED4, thereby causing the third and fourth light emitting diodes LED3 and LED4. Light emitting to indicate that the heat storage steamer 110 is being heated.

Next, since the heat storage steamer 110 is heated, when the power application time is M + 1 minute + addition / deceleration time, the heat storage control signal is not output from the microprocessor 123 to the second relay LY2. Since the second relay LY2 is not excited and the second movable contact c is separated from the second fixed contact d, no current flows through the bimetal 116 to the heating wire 112. 110 to prevent overheating and the resulting fire.

On the other hand, when the time setting switch 124 or the temperature setting switch 125 is pressed three times while the power switch 121 is on (ON), the push count is stored in the storage unit 128 three times, The microprocessor 123 determines whether the temperature in the heat storage steamer 110 is equal to or greater than the overheating prevention temperature, and when the temperature is not greater than the overheating prevention temperature, the third relay LY3 according to the push count of the microprocessor 123. Outputs a power application signal for heating the heat storage steamer 110 for M + 2 minutes + acceleration time.

Next, the third relay LY3 is excited to bring the third movable contact e into contact with the third fixed contact f so that a current flows in the heating wire 112 through the bimetal 116 to heat the heating wire ( The heat dissipation heat from the 112 heats the ceramic heating wire housing 113 and the ceramic insulator 115, which is filled in the heat storage steamer 110, and heat storage for M + 2 minutes + acceleration time, and at the same time, the microprocessor 123 Power supply signal outputted from the current limiting resistor (R3) to flow through the fifth and sixth light emitting diodes (LED5, LED6) to emit the fifth and sixth light emitting diodes (LED5, LED6) to the heat storage Indicates that the steamer 110 is being heated.

Next, since the heat storage steamer 110 is heated, when the power supply time is M + 2 minutes + deceleration time, the heat storage control signal is not output from the microprocessor 123 to the third relay LY3. Since the third relay LY3 is not excited so that the third movable contact e is separated from the third fixed contact f, no current flows in the heating wire 112 through the bimetal 116. 110 to prevent overheating and the resulting fire.

Next, when you want to use the reheating after use, it is heated by connecting the connector 126a to the heat storage steamer 110, if the internal temperature of the heat storage steamer 110 is detected by the temperature detection sensor 117, If the power is not applied when the temperature is higher than the set overheating prevention temperature, the user further uses the heat storage steamer 110, and when the internal temperature falls below the overheating prevention temperature, when the heating is performed, the table illustrated in FIG. According to the user's preference, M / M, M + 1 minute, M + 2 minute, or weak, medium, steel time and temperature settings can be used after reheating. Safety accidents such as burns and fires can be prevented.

As described above, FIG. 6 illustrates three types (M minutes, M + 1 minutes, M + 2 minutes, or about, medium, according to the current internal temperature of the heat storage steamer 110 measured by the sensor for the steaming and the taste of the user). The criteria for appropriately adding and subtracting the power-on time are illustrated as follows. In more detail, when the user heats the heat storage steamer 110 by selecting the 'M + 1 minute' or 'middle' temperature using the time setting switch 124, the temperature detection sensor 117 is detected. The deceleration time is determined by the microprocessor 123 using the diagram shown in FIG. 6 according to the temperature in the heat storage steamer 110, and the deceleration time is applied to the heating time.

For example, when the temperature control device 120 detects the current internal temperature of the heat storage steamer 110, it is to apply power to the heat storage steamer 110 for M + 1 minute at 30 ℃, If the internal temperature is 25 ° C, 30 seconds is additionally added to M + 1 minute to apply power to the heat storage steamer 110 for M + 1 minute + deceleration time (30 seconds). In the case of ℃, it is to subtract 30 seconds to M + 1 minutes to apply power to the heat storage steamer 110 for M + 1 minute + acceleration time (-30 seconds).

In Figure 6, M is preferably in the range of 2 minutes to 6 minutes, more preferably 3 to 4 minutes when the internal temperature of the heat storage steamer 110 is based on 30 ℃.

However, Figure 6 is an exemplary table based only when the internal temperature of the heat storage steamer 110 is 30 ℃, it can be seen that it does not represent the M minutes of the present invention, if the standard is changed is also changed M minutes Points are obvious to those skilled in the art and are included in the present invention.

As such, the heat storage steamer 110 cannot be controlled by directly checking the internal temperature by using a temperature detection sensor or bimetal in order to obtain a desired poultice temperature due to the characteristics of the ceramic heating wire housing 113 and the ceramic heat insulating material 115. By controlling the heating time as described above, the heat storage steamer 110 continuously rising after the heating can be controlled to a user's desired steaming temperature.

In the above description, the specific embodiments have been shown and described, but the present invention is not limited thereto, for example, by those skilled in the art without departing from the concept of the present invention. Of course, the design can be changed in various ways.

As described above, according to the temperature control device and the method of the portable heat storage steamer according to the present invention, the operating temperature is adjusted according to the user's taste through the operation of the time setting or the temperature setting switch and at the same time according to the internal temperature of the portable heat storage steamer. It is possible to prevent burns and fire in consideration of the characteristics of the heat storage steamer equipped with the ceramic heating wire housing 113 and the ceramic insulating material 115, in which the temperature rises for a while even after the heating time by heating for a preset time. If the overheating temperature is higher than the power is cut off is a very useful invention that can prevent the safety accident by preventing overheating of the heat storage steam.
