Accordingly, it is not intended to provide a more detailed structure than is necessary for a basic understanding of the present invention, but it should be understood by those skilled in the art that various forms that can be practiced in the present invention are illustrated in the drawings.

1 is a block diagram showing the configuration of a preferred embodiment of a heating temperature control apparatus of the present invention. Here, reference numeral 110 denotes a jog shuttle switch. The jog shuttle switch 110 is provided with a push bar 114 on the handle 112, as shown in Figure 2a, and the rotation direction detection switch (116a, 116b) in the outer position of the push bar 114 In addition, as the push bar 114 rotates together with the rotation of the handle 112, the rotation direction detection switches 116a and 116b are sequentially connected to each other, and thus, the rotation direction signal F1 having a phase difference of about 90 Hz. , F2) is generated.

In addition, the jog shuttle switch 110 is provided with a mode selection switch 118 at the lower portion of the handle 112, as shown in Figure 2b, the mode selection switch 118 when pressing the handle 112 Is connected to generate a mode selection signal SEL.

Reference numeral 120 is a control unit. The controller 120 includes a timer 122. In addition, the controller 120 sequentially sets a plurality of temperature setting modes and a heating time setting mode according to a mode selection signal SEL generated by the jog shuttle switch 110, and the rotation direction signals F1 and F2. Set the control value of the currently set operation mode. In addition, the controller 120 controls the heating operation to be performed according to the control value of each operation mode during the set heating time while counting the elapsed time with the timer 122.

Reference numeral 130 is a display unit. The display unit 130 displays the currently selected operation mode and control values for each of the currently selected operation modes under the control of the controller 120.

Reference numerals 140, 142 and 144 denote heaters, and reference numerals 150, 152 and 154 denote heaters.

For example, each of the heaters (150, 152, 154) is the upper body heater 150, the waist heater (installed on the site where the upper body, waist and lower body contact each of the human body when using a heating mechanism) 152 and lower body heaters 154. Each of the heater driving units 140, 142, and 144 heats the upper body heater 150, the waist heater 152, and the lower body heater 154 under the control of the controller 120. The sub heater driver 140, the waist heater driver 142, and the lower body heater driver 144.

Reference numerals 160, 162 and 164 each represent a temperature sensor. For example, each of the temperature sensors 160, 162, and 164 may be the upper body temperature sensor 160, the waist temperature sensor 162, and the lower body temperature sensor 164 as the upper body heater 150. The temperature of each of the waist heater 152 and the lower body heater 154 is detected and provided to the controller 120.

The heating temperature control apparatus of the present invention configured as described above selects a mode when the user pulls the handle 112 downward when the user grasps the handle 112 of the jog shuttle switch 110 to set the heating temperature. The switch 118 is connected to generate a mode selection signal SEL.

When the mode selection signal SEL is generated, the controller 120 turns on the power of the heating apparatus, sets the initial operation mode, and controls the display unit 130 to indicate that the initial operation mode is set.

For example, the present invention is applied to a heating device such as an electric blanket and an electric blanket as the initial operation mode to set the overall temperature setting mode for adjusting the heating temperature of the upper body, waist and lower body of the human body to the same temperature and The display unit 130 indicates that the entire temperature setting mode is set.

In this state, the controller 120 determines whether the mode selection signal SEL is continuously input from the jog shuttle switch 110.

When the mode selection signal SEL is input from the jog shuttle switch 110 as a result of the determination, the control unit 120 sequentially sets a plurality of operation modes and controls the display unit 130 to sequentially set the operation mode. Display the mode.

For example, the present invention is the overall temperature setting mode for simultaneously setting the heating temperature of the entire upper body, waist and lower body to the same temperature, the heating temperature of the upper body of the human body, the heating temperature of the waist of the human body and the lower body of the human body There is an upper temperature setting mode, a waist temperature setting mode and a lower body temperature setting mode for setting only the heating temperature, and a heating time setting mode for setting a heating time for performing temperature control. As (SEL) is input, it is set sequentially by cycling through the entire temperature setting mode → upper body temperature setting mode → waist temperature setting mode → lower body temperature setting mode → heating time setting mode → total temperature setting mode. The operation mode is displayed on the display unit 130 so that the user can check it.

Here, it is preferable that the order of the setting modes set sequentially can be changed arbitrarily.

The controller 120 determines whether the rotation direction signals F1 and F2 are input from the jog shuttle switch 110.

When the rotation direction signals F1 and F2 are input from the jog shuttle switch 110, the controller 120 determines the currently set operation mode and rotates the knob 112 of the jog shuttle switch 110. The direction is determined, and the control value of the currently set operation mode is variably set according to the determined rotation direction.

For example, when the knob 122 of the jog shuttle switch 110 is rotated in the forward direction, that is, the clockwise direction, as shown in FIG. 2A, the rotation direction detection switch 116a is first connected, and then the rotation direction detection switch ( As shown in (a) and (b) of FIG. 3, the rotation direction signal F1 generated by the rotation direction detection switch 116a is generated by the rotation direction detection switch 116b. The phase is about 90 Hz ahead of the signal F2.

When the knob 122 of the jog shuttle switch 110 is rotated in the reverse direction, that is, counterclockwise, as shown in FIG. 2A, the rotation direction detection switch 116b is first connected, and then the rotation direction detection switch 116a is rotated. As shown in FIGS. 4A and 4B, the rotation direction signal F2 generated by the rotation direction detection switch 116b is generated by the rotation direction signal F2 generated by the rotation direction detection switch 116a. The phase is about 90 Hz ahead of F1).

The controller 120 sequentially sets a plurality of operation modes according to the mode selection signal SEL, and the knob 122 as the rotation direction signals F1 and F2 are input to each of the set operation modes. Determine the rotation direction and set the control value for the currently set operation mode.

For example, when the rotation direction signals F1 and F2 are input while the current temperature setting mode is set, the temperature control value of the overall temperature setting mode is increased or decreased according to the rotation direction signals F1 and F2.

Also, when the rotation direction signals F1 and F2 are input while the upper body temperature setting mode is currently set, the temperature control value of the upper body temperature setting mode is increased or decreased according to the rotation direction signals F1 and F2.

Also, when the rotation direction signals F1 and F2 are input while the waist temperature setting mode is currently set, the temperature control value of the waist temperature setting mode is increased or decreased according to the rotation direction signals F1 and F2.

Also, when the rotation direction signals F1 and F2 are input while the lower body temperature setting mode is currently set, the temperature control value of the lower body temperature setting mode is increased or decreased according to the rotation direction signals F1 and F2.

In addition, when the rotation direction signals F1 and F2 are input while the current heating time setting mode is set, the heating time control value of the heating time setting mode is increased or decreased according to the rotation direction signals F1 and F2.

Here, a collision may occur when the user sets the control value of the upper body temperature setting mode, the waist temperature setting mode and the lower body temperature setting mode in a state in which the user selects the entire temperature setting mode and sets the control value.

Therefore, in the practice of the present invention, when the user adjusts the temperature control value by setting the overall temperature setting mode, all of the control values of the upper body temperature setting mode, the waist temperature setting mode, and the lower body temperature setting mode are ignored. When the control value is set by selecting any one of the control values of the upper body temperature setting mode, the waist temperature setting mode, and the lower body temperature setting mode, it is preferable to ignore the control value set in the entire temperature setting mode. .

When the control value of each of the plurality of operation modes is set in this way, the control unit 120 uses the upper body heater as the upper body temperature sensor 160, the waist temperature sensor 162, and the lower body temperature sensor 164. 150, the temperature of the waist heater 152 and the lower body heater 154 is determined, and according to the determined temperature and the set temperature control value, the upper body heater driver 140, the waist heater driver 142, and the lower body heater are determined. The driving unit 144 is controlled to cause the upper body heater 150, the waist heater 152, and the lower body heater 154 to generate heat at a temperature according to a set temperature control value.

The controller 120 operates the timer 122 to count the elapsed time, and when the set heating time elapses, the temperature of the upper body heater 150, the waist heater 152, and the lower body heater 154. End the operation of adjusting.
