Description

  The present invention relates to an electric heater such as an electric hot air heater, an electric stove, an electric carpet, and an electric blanket, and more particularly to an electric heater provided with a quick heating function for these devices.

  Conventionally, in this type of electric heater, since the heater used does not have immediate warming properties, even when the power supply to the heater is started, so-called heater is turned on, it takes time to immediately generate heat and rise in temperature. Therefore, when the heater is turned on, it uses a fast heat heater with a large amount of electric power and the amount of heat accompanying it, and after heating for a predetermined time with this heater, it automatically switches to the heater capacity set by the user A temperature control device as described above is provided. (For example, Patent Document 1)

However, in the above temperature control device, in order to change the installation location of the heater, etc., when the heater is temporarily turned off and the heater is turned on again, the rapid heating heater is used with the same warming time as the first time. When heating is performed in the mode, an overheating state exceeding the temperature set by the user, that is, so-called overrun may occur.
Therefore, in order to prevent the overrun, a correction speed warm-up time corresponding to the off time in the individual heater mode is set in advance, and when the power supply to the heater is started again, the correction speed warm-up time is started from the quick warm-up time. In some cases, power is supplied to the rapid warming heater for the difference time obtained by subtracting the time, and switching to the individual heater mode after the difference time has elapsed, thereby shortening the rapid warming time when the power is turned on again. (For example, Patent Document 2 below)

Japanese Utility Model Publication No. 55-159212 JP 2008-25959 A

  By the way, in this conventional device, when the heating level can be set at a plurality of levels from weak to strong, for example, when the heating level is set to low, the heater is temporarily turned off and turned on and off again. If the time is long, the rapid warm-up time is the maximum and the rapid warm-up heater mode is implemented, so the heater temperature rises and the heating level rises to a high level, so the heating level desired by the user is exceeded. There was a problem.

  In order to solve the above problems, the present invention provides a heater, a timer unit, an operation knob for setting a heating level, and a control unit for controlling the heating operation. In the electric heater to be operated, the control unit performs the re-operation according to the time from the stop of the operation timed by the timer unit to the re-operation and the heating level set by the operation knob at the time of the re-operation. The heating level of the rapid warming operation is determined and the rapid warming operation is performed.

  According to a second aspect of the present invention, there is provided an electric heater that includes a heater, a timer unit, an operation knob for setting a heating level, and a control unit that controls the heating operation, and performs a quick warming operation when the operation is restarted after the operation is stopped. And the control unit determines the heating level of the quick warming operation at the time of re-operation by the time from the operation stop timed by the timer unit to the re-operation and the heating level set by the operation knob at the time of re-operation. The quick warming operation time is determined and the quick warming operation is performed.

  According to the first aspect of the present invention, the quick warm-up operation at the time of re-operation is performed by the time from the operation stop time measured by the timer unit to the re-operation and the heating level set by the operation knob at the time of re-operation. Since the heating level is determined and quick heating operation is performed, the heating level is set so that it does not exceed the heating level desired by the user by overshooting the heating level set by the operation knob at the time of restart. It is possible to perform driving and thereby prevent the user from feeling uncomfortable by overshooting.

  Also, by setting the heating level so that the heater temperature rises quickly without overshooting, and performing quick heating operation, unnecessary power consumption due to overshooting can be prevented, and economical rapid heating operation can be performed. Is something that can be done.

  According to the electric heater of claim 2 of the present invention, it is possible to restart the operation by the time from the operation stop time measured by the timer unit to the re-operation and the heating level set by the operation knob at the time of the re-operation. Since the quick heating operation is performed by determining the heating level and the quick heating operation time for the quick heating operation, overheating the heating level set by the operation knob at the time of restarting, the user's desired heating level The heating level and the quick warming operation time can be set so as not to exceed the speed, and the quick warming operation can be performed, thereby preventing the user from feeling uncomfortable by overshooting. .

  In addition, by setting the heating level and the quick warm-up operation time so that the heater temperature can be quickly raised without overshoot, extra power consumption due to overshoot can be further prevented. Economical quick warming operation can be performed.

  Next, an embodiment of the present invention will be described with reference to FIG.

Next, an embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes an electric stove, which is an elliptical plan view and is generally referred to as a cylindrical tower type, and a cylindrical main body case portion 3 having a single heater 2 and a main body case portion 3 having a diameter larger than that of the main body case portion 3. The main body case portion 3 includes a front panel 6 to which a guard 5 that includes a heater 2 and covers a front surface of the heater 2 is attached, and a front panel 6. The rear panel 7 is joined, the front panel 6 is engaged, and the operation unit main body 8 is attached to the upper part of the rear panel 7.

  The heater 2 is made of stainless steel sheathed heater tube with a black ceramic coating, which emits a large amount of 3-20 micron far-infrared rays to warm it from the body's shin, and is resistant to impact and has excellent durability. The heat generating part 10 is configured together with the reflector 9 and the guard 5 that reflect heat.

  The operation unit body 8 is provided with a display unit 11 for displaying the heating capacity at the upper front portion, and an operation unit 12 is provided on the upper surface. The operation unit 12 is a rotary type that sets on / off of heating operation and heating capacity. An operation knob 13, a fluctuation operation switch 14 that raises or lowers the heating capacity within a certain range, a turn-off timer switch 15 that can set an operation time from 30 minutes to 1 to 3 hours, and a swing switch 16 that swings the main body case 3. It is what has.

  A control unit 17 comprising an operation unit board having a microcomputer for controlling the operation unit 12 and various modes is mounted in the operation unit main body 8, and the control unit 17 is used for measuring a predetermined time. A timer unit 18 is provided.

Next, the operation of this embodiment will be described.
The case where the electric stove 1 is stopped from the operating state and then restarted will be described with reference to the flowchart shown in FIG.
First, when it is detected that the operation is stopped from the operation state (S1), the control unit 17 starts the timer unit 18 to start measuring time. (S2)

When it is detected that the operation has been restarted from the operation stop state (S3), the control unit 17 stops the timer unit 18 and ends the time measurement. (S4)
Then, it is determined whether the time measured by the timer unit 18 is less than tmin, or less than 3 minutes in this case (S5). If it is greater than tmin, the time measured by the timer unit 18 and the operation knob 13 at the start of re-operation are set. The heating level and the quick warming operation time for the quick warming operation are determined according to the heating level being used. (S6)

  The following Table 1 is set by the operation knob 13 and the OFF ON time until the operation is stopped from the operation state of the electric stove for determining the heating level and the quick heating operation time for the quick heating operation and the restarting operation in (S6). It represents the relationship with the heating level.

  Then, the timer unit 18 starts measuring time and starts the quick warm-up operation with the heating level and quick warm-up operation time determined in (S6) (S7), and performs the quick warm-up operation time determined in (S6). If this is the case (S8), the timing of the timer unit 18 is terminated and the rapid warming operation is terminated (S9), and the heating operation is continued at the heating level set by the operation knob 13. (S10)

  Further, when the time measured by the timer unit 18 in (S5) is less than tmin, it is determined that the temperature of the heater 2 is high, the rapid heating operation is not performed (S11), and the process proceeds to (S10). The heating operation is continued at the heating level set by the operation knob 13.

  Also, in (S3), when the operation is stopped from the operation stop state and the operation is in the operation stop state, when the time counted by the timer unit 18 is tmax or more, it is determined whether it is 20 minutes or more in this case (S12), When it is equal to or greater than tmax, the timer unit 18 finishes timing (S13), and when the operation is stopped again from the operation stop state (S14), the heating level is set to the maximum Lmax, and in this case, the heating level is set to the maximum 9, The quick warm-up operation time is determined as the maximum Tmax, which is 8 minutes in this case (S15), and then the process proceeds to (S7) to start the timer 18 and the heating level and quick warm-up operation determined in (S15) Rapid warm-up operation starts with time.

  In this case, the warm / warm operation is automatically performed at the time of re-operation, but the present invention is not limited to this. A warm / warm switch is provided in the operation unit body 8 so that the warm / warm operation is performed only when the warm / warm switch is on. Is also good.

  As described above, in this case, the temperature of the heater 2 is determined by measuring the OFFON time until the operation is stopped from the operation state of the electric stove and then the operation is restarted, and the operation knob 13 at the time of the operation is set. The heating level requested by the user is grasped from the heating level, and the heating level and the quick heating operation time for quick heating / running operation are thereby determined. Therefore, the user requests from the temperature of the heater 2 at the start of restart. It is possible to quickly raise the temperature of the heater 2 at the heating level without overshooting, thereby preventing the user from feeling uncomfortable due to overshooting.

  Further, by quickly raising the temperature of the heater 2 without overshooting, unnecessary power consumption can be prevented and an economical quick warming operation can be performed.
