SOLUTION: When a switch is closed, a control means 4 reads a present time from a timer 6, and stores the present time as a t1. Then, the means 4 reads an irregular signal stored in an irregular signal generating means 5, and stores the signal as a Pt. Thereafter, the means 4 controls a radiation amount to the Pt. Subsequently, the means 4 waits for a lapse of a predetermined time (d), and confirms whether it is finished or not. If it is not finished, the means 4 repeats the above operation. That is, the means 4 alters the radiation amount at each predetermined time (d). The time (d) is set to a length sufficient for a human body to sense such as, for example, 3 min. Thus, the radiation amount is set to change irregularly at a time, thereby realizing a heating for feeling a warmth.

[0029]

(Embodiment 1) A first embodiment of the present invention will be described below. FIG. 1 is a block diagram showing the configuration of this embodiment. Reference numeral 1 denotes a radiation irradiating unit that irradiates radiant heat generated from a heat source heated by the heating unit 2, 3 denotes a temperature sensor that measures the temperature of the heating unit 2 or an area in the vicinity thereof, and 4 denotes a control unit that controls the amount of radiant heat irradiation. It is. Reference numeral 5 denotes an irregular signal generating means for storing an irregular signal in time and generating this signal as required, and is connected to the control means 4. Further, a signal of a timer 6 for measuring time is transmitted to the control means 4.

With the above configuration, the radiant heater of this embodiment is
Radiant heat generated from a heat source heated by the heating means 2 is irradiated from the radiation irradiator 1 to heat the surroundings by the radiant heat.

The operation of this embodiment will be described below. 2 and 3 are characteristic diagrams for explaining the characteristics of a human warm receptor and a cold receptor. FIG. 2 is a characteristic diagram showing the acclimatization characteristics of the human warm receptor, in which the vertical axis represents the temperature difference and the horizontal axis represents the time until acclimation occurs. As can be seen from FIG. 2, the warm receptors of the human body acclimate within a few minutes when subjected to a temperature difference of several degrees, which can normally be applied to the human body, and do not feel warm. FIG. 3 shows the reaction characteristics of the warm receptor and the cold receptor, with the ordinate indicating the activity of each receptor and the abscissa indicating the temperature. The cold receiver has an activity characteristic below the temperature T2, in other words, the temperature T2.
With two or more, the cold receptor does not activate and does not feel cold. The warm receiver has an activity characteristic in a temperature range from T1 to T4. Therefore, when a temperature change from the temperature T3 to the temperature T2 is given to the human body, the degree of feeling of warmth is reduced, but the degree of feeling of cold is not felt.

FIG. 4 shows the characteristics of the reaction between the hot and cold receivers when controlled by the control means 4 of this embodiment. That is, the radiation amount Pt of the radiant heat is irregularly increased or decreased in response to the signals from the irregular signal generating means 5 and the timer 6, but the reaction amount of the warming receiver is the amount after the radiation amount of the radiant heat is reduced. It is increasing at the timing of the increase. That is, the degree of feeling warmth is increased. Since the temperature at this time is higher than the temperature at which the cold receiver is activated, the cold receiver does not react. That is, the user does not feel cold even at the timing when the amount of radiation heat decreases.

In this regard, when the radiant heater described in the conventional example is used, the warm receiver / cold receiver generates a reaction as shown in FIGS. FIG. 5 shows a case in which a constant value of radiant heat is continuously applied. That is, since the radiation amount of the radiation heat is constant at Pt, the warm receiver does not feel warmth in a short time. The cold receiver does not react if the temperature at this time is equal to or higher than T3 described in FIG. That is, the user does not feel cold, but does not feel warmth in a short time. FIG. 6 shows characteristics when the temperature detected by the temperature sensor 3 is controlled to be constant. In this case, since the surrounding temperature gradually increases due to the radiant heat, the radiation amount Pt of the radiant heat irradiated by the radiating section temporarily decreases and becomes constant when the ambient temperature is stabilized. Accordingly, the reaction characteristics of the warm receiver are such that after the acclimation is performed in the same manner as the acclimation shown in FIG. 5, the amount of the reaction further decreases gradually. In addition, about a cold receiver, it does not react.

The operation of the control means 4 used in this embodiment will be described below with reference to FIG. FIG. 7 is a flowchart illustrating a control program of the control unit 4 of the present embodiment. When a switch (not shown) is turned on, the control means 4 starts operation, reads the current time from the timer 6 in step 1, and stores it as t1. Subsequently, in step 2, the irregular signal stored in the irregular signal generating means 5 is read and set as Pt. In step 3, control means 4
Controls the radiation amount to the Pt. Step 4 waits for the lapse of a predetermined time d, and checks in step 5 whether or not to end. If not, the process returns to step 1 and returns to step 1.
And the operation of step 5 is repeated. In this way, the control means 4 changes the radiation amount every predetermined time d. In the present embodiment, the predetermined time d is set to a sufficient length for the human body to detect,
For example, it is set to 3 minutes. In addition, when the predetermined time d is short, for example, when it is set to 1 second, the human body cannot feel the change in the radiation amount, so that even if the radiation amount is changed irregularly, a response of the warm receptor is caused. The effect is unlikely.

As described above, according to the present embodiment, since the radiation amount is set to be irregularly changed with time, it is possible to realize radiant heating in which the user can continue to feel warmth.

In addition, since the predetermined time d is set to be long enough to be detected by the human body, the human body can reliably detect a change in the amount of radiant heat, and the heating effect can be further improved.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 8 is a block diagram illustrating the configuration of the present embodiment. Reference numeral 7 denotes a glass tube constituting a radiation irradiating unit for irradiating radiant heat, and reference numeral 8 denotes a combustion chamber disposed below the glass tube 7, which constitutes a heating means. The fuel burned in the combustion chamber 8 radiates radiant heat from the glass tube 7 to warm a human body or the like. An oil supply pipe 9 connected to a fuel motor 10 and an air pipe 11 connected to an air fan 12 are connected to a lower portion of the combustion chamber 8. Reference numeral 13 denotes an ignition electrode for igniting the fuel supplied to the combustion chamber 8. The heating control means 14 controls the fuel motor 10 and the air fan 11. Reference numeral 3 denotes a temperature sensor for measuring the temperature of the combustion chamber 8 or the vicinity thereof.
The heating control means 14 includes a timer 6 for measuring time,
The chaos signal calculation means 15 is connected. The chaos signal calculation means 15 calculates a chaos and outputs a chaos signal. The fuel motor 10 controls the amount of fuel supplied to the combustion chamber 8, and the air fan 12 controls the amount of air supplied to the combustion chamber 8. In other words, the heating control means 14 controls the amount of combustion in the combustion chamber 8 by controlling the fuel motor 10 and the air fan 12. In the present embodiment, the functions of the heating control means 14, the chaos signal calculating means 15, and the timer 6 are realized by using a microcomputer.

The operation of this embodiment will be described below. When the heating control means 14 operates and the fuel motor 10 and the air fan 12 are driven, the oil feed pipe 9 is inserted into the combustion chamber 8.
Is supplied through the air pipe and air is supplied through the air pipe 11. When the user presses the ignition electrode 13 in this state, the fuel starts burning in the combustion chamber 8. The combustion generates radiant heat corresponding to the combustion temperature, and the radiant heat is emitted from the glass tube 7.

At this time, the heating control means 14 of this embodiment
The fuel motor 10 and the air fan 12 are controlled by the chaos signal calculated by the chaos signal calculation means 15. In the natural world, for example, heat from a charcoal fire, a bonfire, or the like has chaos, and the light of the sun also has chaos. The comfort of bonfires and sunflowers is due to the fact that the heat supplied is irregular and temporally irregular, so that the warm receptors of the human body can be activated and the warmth can be continuously felt. The chaos, although seemingly irregular, is not so-called random but can be created by a simple mathematical formula.

The chaos signal calculating means 15 of this embodiment has a chaotic sequence calculated based on a function F (X) as shown in Expression 1.

F (X) = 1− | 2X−1 | (0 ≦ X ≦ 1) (Equation 1) FIG. 9 is a graph showing the function F (X).

Hereinafter, the chaotic signal X is calculated using the function F (X).
A method for calculating n will be described. FIG. 10 is an explanatory diagram for explaining this calculation method. First, let X0 be the first value of the time series Xn, and let it be the initial value of the time series Xn.
Next, the result calculated by substituting X0 into F (X) is expressed as n = 1
Let it be the first value X1. Further, X1 is substituted into F (X) for calculation, X2 is obtained, and similarly, X3 is obtained from X2.
By repeating the above procedure, the time series X0, X
1, X2... Xn can be obtained.

Note that the chaos signal calculating means 15 calculates the F
Although (X) is used, other than this function, a logistic function or the like shown in Expression 2 may be used.

F (X) = 4 · X · (1−X) (0 ≦ X ≦ 1) (Equation 2) Next, the operation of the heating control unit 14 of the present embodiment will be described with reference to FIG.
1 will be described. FIG. 11 shows a calculation program of the chaos signal which the heating control means 14 has.
The chaos signal calculation means 15 performs calculation based on the instruction from the heating control means 14 and transmits the result to the heating control means 14. First, in step 121, a parameter representing time is set to n = 0, and in step 122, an initial value of the chaos function F (Xn) is set to X0. Then step 12
In step 3, F (Xn) is calculated, the result is substituted for the next (n + 1) th value Xn + 1, and the value is stored. Next, at step 124, 1 is added to n. Subsequently, in step 125, it is checked whether or not the user has finished heating. If the result of the check in step 125 is NO, steps 123 to 125 are repeated. If the result of the check in step 125 is YES, the process ends.

The heating control means 14 controls the fuel motor 10 and the air fan 12 using the chaos signal thus obtained. When the radiant heating is started, the first chaos signal X1 is read, and a control signal is output to the fuel motor 10 and the air fan 12 so as to generate a corresponding combustion amount Pt, for example, Pt = Xn * P0 + P1. Then 2
The second chaos signal X2 is read, and a control signal is output by a similar process. The control signal is generated from the chaos signal Xn until the heating is completed, and the fuel motor 10
And the air fan 12 are controlled. When the heating is completed, the process ends. In this way, a radiation amount corresponding to the magnitude of the chaotic signal can be generated. FIG. 12 is an explanatory diagram illustrating the relationship between the chaos signal and the combustion state in the combustion chamber 8 as a result of this control. FIG. 12A shows a combustion state in the combustion chamber 8, and FIG. 12B shows a chaos signal. The amount of combustion Pt in the combustion chamber 8 is determined by the chaos signal Xn.
It changes with a shape similar to. That is, the combustion is chaotic.

The relationship between the amount of combustion, the amount of fuel to be supplied, and the amount of air to be supplied is considered to be a simple proportional relationship. That is, in order to obtain a large amount of combustion, the amount of supplied fuel is increased and the amount of supplied air is also increased. For example, if the supplied fuel amount is Ft and the supplied air amount At,
t and At can be controlled by the equations shown in Equations 3 and 4.

Ft = a * Pt (Equation 3) At = b * Pt (Equation 4) As described above, according to the present embodiment, since the amount of heating is controlled in accordance with the chaos signal abundantly found in the natural world, It is possible to perform heating that continues to feel comfortable warmth close to heating, and it is also possible to realize efficient heating by the piconet effect. In addition, since the amount of radiant heat generated by controlling the amount of combustion is changed, irradiation of radiant heat irregular in time can be realized with a simple configuration.
Further, by having a chaotic operation expression, it is possible to continuously generate a chaotic signal indefinitely. Further, by irradiating radiant heat according to the magnitude of the chaos signal, the heating effect can be enhanced by continuously changing radiation.

Third Embodiment Next, a third embodiment of the present invention will be described. FIG. 13 is a block diagram showing the configuration of this embodiment. In this embodiment, a shutter 18 is provided in the glass tube 7. In this embodiment, the shutter 18 is made of a metal plate to withstand high temperatures. The opening and closing of the shutter 18 is controlled by the irradiation control unit 16.
By driving a motor (not shown). The chaos signal storage means 17 and the timer 6 are connected to the irradiation control means 16. The chaos signal storage unit 17 stores the chaos sequence described in the second embodiment. In this embodiment, the irradiation control means 16 and the chaos signal storage means 17 are realized by a microcomputer.

The operation of this embodiment will be described below. The irradiation control unit 16 drives a motor (not shown) to open and close the shutter 18 based on the chaos signal Xn stored in the chaos signal storage unit 17. In this embodiment, the chaotic signal storage unit 17 stores N chaotic sequences in advance. The irradiation control means 16 first
When the radiant heating is started, the first chaos signal X1 is read and compared with a predetermined threshold value X0. When the chaos signal X1 is larger than the threshold value X0, the shutter 18 is opened to turn on the irradiation, and when the chaos signal X1 is equal to or less than the threshold value X0, the shutter 18 is closed and the irradiation is turned off. Next, the second chaos signal X2 is read, and a control signal is output in a similar process. After repeating this process up to the number N of the stored chaotic sequence, the process returns to X1 and repeats the same operation. As described above, the control signals for turning on and off the irradiation are generated from the chaos signal Xn until the heating is completed, and the process is terminated when the heating is completed. FIG. 14 is an explanatory diagram for explaining the relationship between the chaos signal Xn stored in the chaos signal storage means 17 and the irradiation amount Pt of the radiant heat emitted from the glass cylinder 7. During the value of the chaos signal Xn is larger than the threshold value X ₀ shutter 18 is open, while the value of the chaos signal Xn is smaller than the threshold value X ₀ shutter 18 is closed. Therefore, the irradiation amount Pt of the radiant heat emitted from the glass tube 7 corresponds to the chaos signal.

As described above, according to the present embodiment, since the glass cylinder 7 is opened and closed by the shutter 18, the amount of radiant heat applied can be reduced with a simple configuration while the combustion state in the combustion chamber 8 is kept constant. It can be controlled so as to be irregular in nature. Further, according to this embodiment, since the chaos signal storage means 17 stores the sequence of chaos, it is possible to use a low-function microcomputer which cannot perform the chaos operation. In addition, since the chaotic signal is converted into an on / off binary value by comparing the chaotic signal with a threshold value and used for control, a simple configuration can be controlled.

(Embodiment 4) Next, a fourth embodiment of the present invention will be described. FIG. 15 is a block diagram showing the configuration of this embodiment. In this embodiment, an irradiation duty control unit 19 is used in place of the irradiation control unit 16 of the third embodiment described with reference to FIG. That is, in the present embodiment, the chaotic signal obtained from the chaotic signal storage means 17 is converted into a duty for opening and closing the shutter 18.

The operation of this embodiment will be described below. FIG. 16 is an explanatory diagram showing the relationship between the chaos sequence and the duty used in the present embodiment. In the example shown in FIG. 16, the duty is used as the on-time during 5 minutes. In other words, the radiant heat for closing the shutter 18 is off for (5-duty) minutes. Thus, the duty cycle is started from the output of the timer 6, and the shutter 18 is opened and closed by the duty time shown in FIG. In the above description, the on-time is first determined by the duty shown in FIG. 16, and then the off-time is determined. However, conversely, the off-time is determined and the warm-up time is determined later. Even so, there is no problem.

As a result, this embodiment has the same effect as the third embodiment. In particular, according to the present embodiment, the control of the irradiation of the radiant heat is controlled as the ON time within the predetermined time, so that the control program can be easily managed.

(Embodiment 5) Next, a fifth embodiment of the present invention will be described. FIG. 17 is a block diagram showing the configuration of this embodiment. The control of the fuel motor 10 and the air fan 12 is performed by the second heating control means 22.
The second heating control means 22 includes a timer 6, a chaos signal calculation means 15, an average value input means 20, and a change width input means 2.
1 is connected. The timer 6 and the chaos signal calculating means 15 are the same as those described in the second embodiment.
The average value input means 20 is for the user to set and input a desired time average value of the amount of radiation heat radiation. The change width input means 21 is for the user to set and input a desired change width of the amount of radiation heat irradiation.

The operation of this embodiment will be described below. FIG. 18 is an explanatory diagram illustrating the combustion amount controlled by the present embodiment. FIG. 18A shows the amount of combustion in the combustion chamber 8, and FIG. 18B shows the chaos signal Xn. The second combustion control means 22 controls the combustion amount Pt according to the chaos signal Xn. At this time, since the user has input the average value Pc to the average value input means 20 and the change width W to the change width input means 21, the second heating control means 22 is shown in FIG. The chaos signal Xn is calculated as an average value P
c, the maximum value Pc + W / 2 and the minimum value Pc−W / 2 are converted to drive the fuel motor 10 and the air fan 12. As a result, as shown in FIG. 18A, the combustion amount Pt of the fuel combusted in the combustion chamber 8 has an average value of P
At c, the chaos changes with the maximum value being Pc + W / 2 and the minimum value being Pc-W / 2.

The amount of combustion Pt in the combustion chamber 8 is Pt = Pc +
By setting W * (Xn-0.5), a conversion having the above characteristics can be obtained.

As described above, according to the present embodiment, since the average value of the user's preference and the range of change of the user's preference can be set, the radiation can be radiated with the heating intensity according to the user's preference. A radiant heater having a chaotic effect while heating can be realized.

(Embodiment 6) Next, a sixth embodiment of the present invention will be described. FIG. 19 is a block diagram showing the configuration of this embodiment. In this embodiment, the third heating control means 25 controls the fuel motor 10 and the air fan 12. The timer 6, the chaos signal calculating means 15, the maximum value input means 23, and the minimum value input means 24 are connected to the third heating control means 25. The timer 6 and the chaos signal calculating means 15 are the same as those described in the second embodiment. The maximum value input means 23 is for the user to set and input a desired maximum value of the amount of radiation heat irradiation. The minimum value input means 24 is for the user to set and input a desired minimum value of the amount of radiation heat radiation.

The operation of this embodiment will be described below. FIG. 20 is an explanatory diagram illustrating the combustion amount controlled by the present embodiment. In this embodiment, since the user inputs the maximum value Pmax to the maximum value input means 23 and the minimum value Pmin to the minimum value input means 24, the third heating control means 25
Represents the maximum value Pmax and the minimum value Pmin of the chaotic signal Xn.
And the fuel motor 10 and the air fan 12 are driven. As a result, the combustion amount Pt of the fuel combusted in the combustion chamber 8 has a maximum value of Pmax and a minimum value of Pm
The chaos change is in. That is, the third combustion control unit 25 determines the combustion amount Pt according to the chaos signal Xn.
Is greater than the maximum value Pmax, the maximum value is Pmax. If the value is less than the minimum value Pmin, the minimum value is Pmin. In other cases, the value is Pt according to the chaos signal.

As described above, according to this embodiment, the maximum value and the minimum value of the amount of combustion can be defined, and the user can set the desired maximum value and minimum value. . For this reason, the radiant heat radiated from the glass cylinder 7 does not become too strong or too weak, and a radiant heater having a chaotic effect can be realized.

Embodiment 7 Next, a seventh embodiment of the present invention will be described. FIG. 21 is a block diagram showing the configuration of this embodiment. In this embodiment, the fuel motor 10 and the air fan 12 are controlled by the fourth heating control means 28. The timer 6, the chaos signal 1 storage means 26, and the chaos signal 2 storage means 27 are connected to the fourth heating control means 28. The chaos signal 1 storage means 26
The first chaotic signal is stored. The chaos signal 2 storage means 27 stores a second chaos signal. The fourth heating control means 28 selects and uses one of the two chaotic signal storage means.

Hereinafter, the operation of this embodiment will be described. FIG. 22 shows a heating control program provided in the fourth heating control means 28 of the present embodiment. In step 231, the fourth heating control means 28 reads the time from the timer 6 and stores it as t1. Subsequently, in step 232, the first chaos sequence stored in the chaos signal 1 storage means 26 is read and set as P1t. In step 233, the amount of radiation is controlled to P1t. Step 234 waits for the predetermined time d to elapse, and step 235 checks whether the time tc has elapsed.
Steps 235 are repeated from 1 to control the amount of radiation while reading the chaotic signal 1 sequentially. When the time tc elapses, the same operation is repeated by the chaos signal from the chaos signal 2 storage means 27.

FIG. 23 shows a change in the combustion amount Pt of the fuel burned in the combustion chamber 8 as a result of executing the above control.
For example, when using radiant heating after returning from a cold outdoors, it is desirable that the heating be such that the temperature of the body surface is first raised quickly by strong heating and then slowly warmed up. Therefore, in this embodiment, at the start of heating, the chaos sequence 1 showing a relatively large average value is used so that the time average of the combustion amount becomes large, and after an appropriate time tc has elapsed,
The chaotic sequence 2 showing a relatively small average value is used.
Accordingly, the characteristics of the combustion amount Pt are different from those before the time tc and at the time tc.
It is different from the following.

As described above, according to the present embodiment, since a plurality of chaotic signals are stored by the chaotic signal storing means 1 and the chaotic signal storing means 2, a radiant heater which can be properly used as required is realized. You can do it. Further, the chaos signal to be used can be selectively used depending on the lapse of time from the start of the operation.

Embodiment 8 Next, an eighth embodiment of the present invention will be described. FIG. 24 is a block diagram showing the configuration of this embodiment. In this embodiment, the fifth heating control means 29 controls the fuel motor 10 and the air fan 12. The timer 6, the chaos signal 1 storage means 26, the chaos signal 2 storage means 27, and a room temperature sensor 30 for measuring room temperature are connected to the fifth heating control means 29. The chaos signal 1 storage means 26 stores a first chaos signal. The chaos signal 2 storage means 27 stores a second chaos signal. The fourth heating control means 28
One of these two chaotic signal storage means is selected and used.

The operation of this embodiment will be described below. FIG. 25 shows a control program provided in the fifth heating control means 29 of this embodiment. When the operation is started, the fifth heating control means 29 reads the time from the timer 6 in step 251 and stores it as t1. Subsequently, in step 252, the first chaos sequence stored in the chaos signal 1 storage means 26 is read and set as P1t. In step 253, the radiation amount of the radiation heat is controlled to P1t. Step 254 waits for the predetermined time d to elapse, and then returns to step 255
To check whether the room temperature Ta has reached the target temperature Tm. As long as the result of the check in step 259 is No, steps 251 to 255 are repeated,
The radiation amount is controlled while sequentially reading the chaotic signal 1.
If the result of the check at step 255 is YES, that is, when the room temperature Ta reaches the target temperature Tm, the chaos signal is read from the chaos signal 2 storage means 27 and the same operation is repeated.

That is, when radiant heating is started in a state where the room temperature is low, that is, when the difference between the target temperature and the current temperature is large, the temperature is quickly increased by strong heating until the target temperature is reached. After that, radiant heating is performed slowly. Therefore, when the measured temperature is lower than the target temperature, the chaos sequence 1 showing a relatively large average value is used so that the time average of the combustion amount becomes large, and a relatively small average value is shown after the room temperature reaches the target value. The chaotic sequence 2 is used.

FIG. 26 shows the relationship between the combustion amount Pt and the chaos signal Xn when the above control is executed. That is,
The characteristic of the combustion amount Pt shown in FIG.
The chaos signal Xn shown in (b) follows the chaos sequence 2 from the moment when the room temperature at which the chaos sequence 1 is switched to the chaos sequence 2 reaches the target value.

As described above, according to the present embodiment, the chaos signal to be used is selected based on the difference between the target temperature and the current temperature, so that the heating according to the room temperature is performed while the order of the warm receptors of the human body is maintained. Thus, effective radiant heating can be performed while preventing the occurrence of heat.

(Embodiment 9) Next, a ninth embodiment of the present invention will be described. FIG. 27 is a block diagram showing the configuration of this embodiment. In the present embodiment, the fuel motor 10 and the air fan 12 are controlled by the sixth heating control means 31. The timer 6, the chaos signal calculating means 15, and the switch 32 are connected to the sixth heating control means 31. The switch 32 is a changeover switch for starting or stopping the operation in the chaotic state. The sixth heating control means 31 of the present embodiment receives the signal from the chaos signal calculating means 15 while the switch 32 is on, that is, when operating in a chaotic state, and receives the signal from the chaos signal calculation means 15 to calculate the combustion amount by the chaos signal. The control is performed. Further, when the switch 32 is in the off state, that is, when the operation in the chaotic state is stopped, the combustion control for keeping the combustion amount constant is performed.

Hereinafter, the operation of this embodiment will be described. FIG. 28 shows a control program of the sixth combustion control means 31 of this embodiment. After the start of the operation, in step 291, the sixth combustion control means 31 reads the time from the timer 6 and stores it as t1. Next step 292
Thus, the sixth combustion control means 31 determines whether the switch 32 is on. That is, it is determined whether the user has turned the switch 32 on or off. If on, go to step 293; if off, go to step 2
Go to 95. At step 293, the chaotic sequence calculated by the chaotic signal calculating means 15 is read and set as Pt. Subsequently, at step 294, the sixth combustion control means 31 controls the amount of radiant heat to the Pt. If the switch 32 is off, that is, if the result of the check in step 292 is N
If it is o, the radiation amount of the predetermined radiation heat is set to Pc in step 295. In any case, the elapse of time d is waited in step 296, and it is confirmed whether or not to end in step 297.
97 is repeated.

FIG. 29 shows the relationship between the combustion amount Pt and the chaos signal Xn when the above control is executed. That is,
The combustion amount Pt is determined while the chaos signal Xn is being output.
This is in accordance with the chaos signal Xn, and is constant while the chaos signal Xn is not output.

As described above, according to the present embodiment, by providing the switch 32, the user can freely set whether to perform heating in a chaotic state or to perform heating in a constant state. In other words, switch 3 according to preference and situation
2 can be turned on or off to carry out chaotic heating and radiant heating with constant combustion.
