  However, the above-described conventional infrared ray generator (heater) still has the following problems to be improved.

  First, when this type of heater is provided with a temperature control function that automatically adjusts the amount of combustion so that the outside air temperature becomes the set temperature, this temperature control function, due to its nature, makes the heater a heating capacity. When used in a suitable room, etc., it functions correspondingly, but when used outdoors or in similar environments where air flows, it does not function substantially, and operation continues with maximum output (maximum combustion amount). End up. On the other hand, depending on the use environment, there are many cases where it is sufficient to locally heat a predetermined area, and when the maximum output continues, it may become too hot. As described above, since this type of commercial heater is used for a wide variety of applications, there is an aspect in which wasteful combustion consumption is inherently likely to occur, and further improvement can be achieved from the viewpoint of energy saving and economy.

And a control unit 2 that selects operation control patterns Xa, Xb, and Xc corresponding to the detected outside air temperature To and controls operations of the heaters H and He according to the selected operation control patterns Xa. To do.

  In this case, according to a preferred aspect of the invention, the heater H can be configured to include an infrared radiation panel 5 that emits infrared rays by burning liquid fuel. In addition to the energy saving operation mode Me, the control unit 2 includes a normal operation mode Mn in which the combustion amount can be manually set, and a temperature control operation mode Mc that performs feedback control on the temperature so that the outside air temperature To becomes a set temperature. One or both can be configured.

  According to the operation control method and apparatus 1 for a heater according to the present invention as described above, the following remarkable effects can be obtained.

Can be obtained.

  Next, the best embodiment according to the present invention will be given and described in detail with reference to the drawings.

  First, the outline | summary of the heater H which mounts the operation control apparatus 1 which concerns on this embodiment is demonstrated with reference to FIG.

  The heater H shown in FIG. 3 is an infrared heat radiation type commercial portable heater. The heater H includes a fuel tank 51, and has a pair of casters (wheels) 52 on one side in the longitudinal direction on the bottom surface of the fuel tank 51 and a frame portion 53 fixed to the side surface of the fuel tank 51. The leg portion 53f and the handle portion 53h are integrally formed by the frame portion 53. An infrared heater 55 is disposed on the upper surface of the fuel tank 51 via a swivel base (swing device) 54. The infrared heater portion 55 is covered with a housing portion 56, and the infrared radiation panel 5 is disposed in the front opening of the housing portion 56. This infrared heat radiation panel 5 is entirely formed of a perforated plate using a material that emits infrared light when burning kerosene which is a liquid fuel. Furthermore, the combustion part 22 is provided inside the housing part 56 and behind the infrared radiation panel 5. The combustion unit 22 includes a combustion chamber provided with a gasification burner, a combustion fan that blows air to the combustion chamber, and the like. On the other hand, a control box portion including the operation control device 1 according to the present embodiment is disposed in the partitioned area inside the housing portion 56, and air is blown forward to the front upper portion of the housing portion 56. A fan (circulator) 57 is provided.

  Thereby, the kerosene supplied from the fuel tank 51 is vaporized and then mixed with air, and the resulting mixed gas burns. At this time, a blue flame (blue frame) is obtained by the gasification burner, and the infrared radiation panel 5 is heated by the blue flame. Then, infrared rays are radiated (radiated) forward from the infrared radiation panel 5. The flame temperature of the blue flame is about 300 [° C.] higher than that of the red flame, and the infrared radiation panel 5 is efficiently heated by this blue flame. FIG. 4 shows the heat radiation range characteristics of the heater H.

  Thus, if the heater H is provided with the infrared radiation panel 5 that emits infrared rays by burning kerosene, it is possible to enjoy the merits of infrared rays, particularly far infrared rays that have high heat absorption and heat retention properties for the body. Therefore, there is an advantage that a good heating effect can be maintained by efficient heating even when the energy saving operation mode Me described later is switched to the second operation Ps where the combustion amount is reduced.

  Next, the configuration of the electric system including the operation control device 1 according to this embodiment mounted on the heater H of FIG. 3 will be described with reference to FIG.

  In FIG. 2, reference numeral 1 denotes a block system diagram of the operation control device. The operation control device 1 includes a control unit 2 that controls the operation of the heater H. The control unit 2 includes a control unit main body 11 having a computing function with a built-in CPU and the like. The control unit main body 11 includes a control program and various data for executing an operation control method according to the present embodiment to be described later. Is attached. The input port of the control unit main body 11 is connected to an outside air temperature sensor 3 that detects the outside air temperature To and an operation panel 13 that performs various switching operations and displays. The operation panel 13 is disposed on the back surface of the housing portion 56 in the heater H of FIG. 3 and can be arbitrarily operated by the user. The operation panel 13 includes an operation mode selection button 13m, and at least an energy saving operation mode Me whose operation is controlled by the operation control method according to the present embodiment can be selected. The illustrated operation mode selection button 13m includes, in addition to the energy saving operation mode Me, a normal operation mode Mn capable of manually setting the combustion amount, and a temperature control operation mode for performing feedback control on the temperature so that the outside air temperature To becomes a set temperature. Mc is provided. In addition, the operation panel 13 has a display unit capable of displaying the outside air temperature To, the set temperature, and the like, operation buttons such as an operation / stop button, an operation time (timer) button, an oscillation button, a power lamp, It is equipped with indicator lamps such as alarm lamps and refueling lamps.

  On the other hand, the combustion unit 22 is connected to the output port of the control unit main body 11 via the driver 21. In this case, the combustion unit 22 includes a control valve that adjusts the amount of kerosene supplied, a fan motor that drives the combustion fan, an ignition unit, and the like. A fan motor 24 for driving the blower fan 57 is connected to the other output port of the control unit body 11 via the driver 23, and the oscillation device is connected to the other output port via the driver 25. A swing motor 26 for neck vibration action built in 54 is connected.

  Next, an operation control method according to this embodiment including the operation of the operation control apparatus 1 configured as described above will be described with reference to FIGS.

  First, in the control unit 2, the first operation time Δtfa, Δtfb, Δtfc for performing the first operation Pf at least from the start of the first operation Pf and the operation start to as the energy saving operation mode Me, and the first operation. A plurality of different operation control patterns Xa, Xb, Xc including a second operation Ps having a smaller combustion amount than the first operation Pf performed after the elapse of time Δtfa... Are set in correspondence with the outside air temperature conditions. The energy saving operation mode Me can be selected by an operation mode selection button 13m provided on the operation panel 13.

  FIG. 5 illustrates an operation control pattern in the energy saving operation mode Me. First, the maximum output of the heater H is set for the first operation Pf with a large combustion amount, and 40 to 80% of the maximum output is set for the second operation Ps. An example is 60 [%]. Thus, if the maximum output of the heater H is set in the first operation Pf and 40 to 80 [%] of the maximum output is set in the second operation Ps, kerosene without impairing the original heating effect. Optimum performance can be obtained from the viewpoint of securing the consumption saving. In addition, the air flow rate is also set corresponding to the first operation Pf and the second operation Ps, and the air flow is set in the strong wind mode in the first operation Pf, and the air flow is set in the low wind mode in the second operation Ps. In particular, the low wind mode of the second operation Ps is set in consideration of noise reduction while ensuring the heating effect. In addition, although ventilation is applied to ventilation by the ventilation fan 57, you may apply to other ventilation fans, such as a combustion fan, as needed.

  The three different operation control patterns Xa, Xb, and Xc corresponding to the outside air temperature condition are the same in the first operation Pf (maximum output) and the second operation Ps (60% of the maximum output). In addition to the setting, the first operation times Δtfa, Δtfb, Δtfc are set differently. For example, as an example, the first operation time Δtfa can be set to 1 [hour], the first operation time Δtfb can be set to 0.5 [hour], and the first operation time Δtfc can be set to 0 [hour]. On the other hand, the first condition (for example, -1 [° C] or lower), the second condition (for example, 0 to 9 [° C]), and the third condition (for example, 10 [° C] or higher) are set as the outside air temperature conditions. The first condition corresponds to the operation control pattern Xa that sets the first operation time Δtfa, the second condition corresponds to the operation control pattern Xb that sets the first operation time Δtfb, and the third condition Each operation time Δtfc is set to correspond to the set operation control pattern Xc.

  Next, the operation | movement at the time of the driving | operation of the heater H is demonstrated with reference to the flowchart shown in FIG.

  First, when using the heater H, the user turns on the operation button of the operation panel 13. Then, the desired operation mode is selected by the operation mode selection button 13m. Assume that the energy saving operation mode Me is selected (step S1). Thereby, the control part 2 detects the outside temperature To by the outside temperature sensor 3 (step S2). Since the detection result of the outside air temperature To is given to the control unit main body 11, the control unit main body 11 determines whether the detected outside air temperature To corresponds to the first condition, the second condition, or the third condition. (Steps S3, S4, S5).

  At this time, for example, if the outside air temperature To is below the freezing point of −2 ° C. when the outside air temperature To is below the freezing point of −2 ° C., it is set in advance in order to correspond to the first condition (−1 ° C. or lower). The operation control pattern Xa is selected, and the control unit 2 starts an operation based on the operation control pattern Xa (steps S3 and S6). That is, the operation of the heater H is controlled according to the operation control pattern Xa. At this time, since the stabilization operation for stabilizing the combustion is performed by turning on the operation button that becomes the operation start ts, the first operation Pf is performed after a predetermined time Δth for performing the stabilization operation has elapsed. The stabilizing operation corresponds to the warming-up operation of the automobile, and is operated for several minutes with an output that is at least smaller than the maximum output of the heater H (step S7). As described above, if the first operation Pf is performed after the stabilization operation is completed, the maximum output (first operation Pf) of the heater H is continued from the operation start to. In addition, it is possible to avoid a problem that an unnecessary load, stress, or the like is added to the heater H, and it is possible to contribute to prevention of trouble such as a failure in the heater H and extension of the life.

  Then, when the predetermined time Δth has elapsed (stabilization operation is completed), the process proceeds to the first operation Pf (step S8). Thereby, combustion is performed with the maximum output (combustion amount), and blowing is performed in the strong wind mode. In the case of the operation control pattern Xa, the first operation Pf continues for the first operation time Δtfa (1 [time]) from the operation start to. The operation start to is when the energy saving operation mode Me is selected by the operation mode selection button 13m. If the first operation time Δtfa has elapsed, the process proceeds to the second operation Ps (steps S9 and S10). In the second operation Ps, combustion is performed with an output (combustion amount) of 60% of the maximum output. At this time, in the second operation Ps, the air blowing is in a low wind mode, and the heater H is reduced in noise. In the operation control pattern Xa shown in FIG. 5, the second operation Ps continues unless the operation of the heater H is stopped or the energy saving operation mode Me is stopped (step S11).

  On the other hand, if the outside air temperature To is a cold of about 5 [° C.], a preset operation control pattern Xb is selected to correspond to the second condition (0 to 9 [° C.]), and the control unit 2 starts an operation based on the operation control pattern Xb (steps S4 and S12). Further, since the stabilization operation is performed, when the stabilization operation is completed, the first operation Pf is performed (steps S13 and S14). Thereby, combustion is performed with the maximum output. In the case of the operation control pattern Xb, the first operation Pf continues from the operation start to to the first operation time Δtfb (0.5 [time]). Then, when the first operation time Δtfb has elapsed, the process proceeds to the second operation Ps, and combustion is performed with the output (combustion amount) of 60 [%] of the maximum output (steps S15 and S10).

  On the other hand, if the outside air temperature To is about 15 [° C.] that is not so cold, a preset operation control pattern Xc is selected and controlled in order to cope with the third condition (10 [° C.] or higher). The unit 2 starts an operation based on the operation control pattern Xc (steps S5 and S16). Further, since the stabilization operation is performed, when the stabilization operation is completed, the first operation Pf is shifted (steps S17 and S18). Thereby, combustion is performed with the maximum output. In the case of the operation control pattern Xc, since the first operation Pf is set to the first operation time Δtfc (0 [hour]) from the operation start to, the first operation Pf is immediately performed without performing the first operation Pf. Then, combustion is performed with an output (combustion amount) of 60% of the maximum output (steps S19 and S10).

  The case where the energy saving operation mode Me is selected has been described above. However, when the normal operation mode Mn is selected with the operation mode selection button 13m, continuous operation is performed with the combustion amount manually set from the operation start ts. The manual setting can be selected and set from the combustion amount set in stages on the operation panel 13. Further, when the temperature control operation mode Mc is selected by the operation mode selection button 13m, feedback control for the temperature is performed so that the outside air temperature To becomes the set temperature. The set temperature can be set by the operation panel 13. In this way, in addition to the energy saving operation mode Me, if one or both of the normal operation mode Mn and the temperature control operation mode Mc are provided, even for the business-use heater H used in various applications, The optimum energy saving and heating effect can be obtained in each environment used.

  Therefore, according to the operation control method and the apparatus 1 according to the present embodiment, it is a business-use heater H that is used for a wide variety of purposes and has an aspect in which wasteful combustion consumption is inherently easily performed. However, when the energy saving operation mode Me is selected, the operation control by the optimum operation control pattern Xa... Combined with the magnitude of the combustion amount can be performed corresponding to the outside air temperature To when the operation is started. As a result, effective consumption savings for kerosene can be achieved. FIG. 6 shows the annual kerosene consumption [liter] in the energy saving operation mode Me and the normal operation mode Mn. This data is a calculated value when the outside air temperature To is 5 [° C.], the consumption of kerosene per hour at the maximum output is 4.2 [liter], 8 hours a day, and 60 days a year. That is, the energy saving operation mode Me is calculated by (4.2 liters / hour) × 0.5 hours + (2.5 liters / hour) × 7.5 hours × 60 days, and the normal operation mode Mn is (4 .2 liters / hour) × 8 hours × 60 days. As described above, by using the energy saving operation mode Me, it is possible to dramatically improve energy saving and economical efficiency when using the heater H.

  Further, by selecting the energy saving operation mode Me, the operation control by the optimum operation control pattern Xa... Combined with the magnitude of the combustion amount is automatically performed, so that manual setting of the combustion amount by the user becomes unnecessary. Therefore, even when used for business purposes such as in a factory or at a work site, it is possible to eliminate or greatly reduce the occurrence of time loss due to interruption of work and the like, and further the adverse effect on work contents.

  Next, a modified embodiment of the operation control method and apparatus 1 for a heater according to the present invention will be described with reference to FIGS.

  FIG. 7 shows an operation control pattern Xe according to the modified embodiment. Although FIG. 5 shows basic operation control patterns (Xa, Xb, Xc), the operation control pattern Xe shown in FIG. 7 further includes the second operation control for the basic operation control pattern. A pattern is added. For example, the temperature may fluctuate greatly during the day, and even if the operation is continued by the second operation Ps, it may be unexpectedly cold. Therefore, when a certain outside air temperature condition is reached, the first operation Pf is performed again. In the operation control pattern Xe shown in FIG. 7, the first operation Pf is set to 80 [%] of the maximum output, the second operation Ps is set to 50 [%] of the maximum output, and the first operation Pf is started. After the first operation time Δtfp is performed from to, the process proceeds to the second operation Ps. These operations form a basic operation control pattern. On the other hand, after this, the outside air temperature To is monitored, and when the outside air temperature To falls to the set outside air temperature condition (or the arbitrarily set temperature), the first operation Pf is performed again for the second operation time Δtfq. Do. The first operation Pf in the second operation time Δtfq may be performed with the same output as the first operation Pf for the first time, or may be performed with a different output. Or you may perform ventilation with the low wind mode. In FIG. 7, Xem indicates an operation control pattern performed with the same output, and Xes indicates an operation control pattern performed with a different output. The second operation control pattern added in this way can be repeatedly performed. The virtual line indicates the basic operation control pattern Xa described above.

  As described above, the preset operation control pattern can be implemented by various operation control patterns on the condition that at least the basic operation control pattern is included. In this case, the operation control pattern is not so fixed as shown in FIG. It may be a control pattern or an operation control pattern that changes according to the conditions shown in FIG. In FIG. 7, the same parts as those in FIG.

  FIG. 8 shows a heater He according to a modified embodiment.

If an infrared radiation type heating device H as shown in FIG. 3 is used, as described above, the benefits of far infrared rays that are highly heat-absorbing and heat-retaining for the body can be enjoyed. Even when the second operation Ps is switched to a small value, there is an advantage that a good heating effect can be maintained by efficient heating. On the other hand, even in the case of a warm air type heater He as shown in FIG. 8, energy saving and economical efficiency in use, further noise reduction, and manual adjustment of the combustion amount by the user are unnecessary. The operation control method and apparatus 1 according to this embodiment (the present invention) can be applied to various types of heaters H, He.

  The heater He shown in FIG. 8 includes a fuel tank 61. The bottom surface of the fuel tank 61 has a pair of casters (wheels) 62 on one side in the longitudinal direction and a pair of legs on the other side in the longitudinal direction. 63. The fuel tank 61 has a frame portion 63 fixed to the side surface. The frame portion 63 integrally forms a handle portion 63h and a heater support portion 63s, and the heater support portion 63s supports the heater portion 65. The heater portion 65 includes a cylindrical housing portion 66, and a hot air port 66 h is provided at the tip of the housing portion 66. Further, the housing portion 66 includes a combustion portion including a combustion chamber provided with a burner and a strong wind generating fan. On the other hand, a control box portion 67 including the operation control device 1 according to the present embodiment is disposed outside the housing portion 66. As a result, the kerosene supplied from the fuel tank 61 is burned by the burner, and the generated heat is released (heat radiated) forward from the warm air port 66h by the strong wind from the strong wind generating fan.
