。INDUSTRIAL APPLICATION FIELD The present invention relates to a heating capacity control device for hot air heaters and the like. 2. Description of the Related Art In general, this type of heating capacity temperature control device changes its heating capacity from strong to weak depending on the difference between a set temperature and the room temperature. Therefore, when starting heating when the room temperature is low, heating is started at the maximum (strong) heating capacity, and after the room temperature reaches the set temperature, heating at the maximum heating capacity is canceled and the heating capacity is determined by the difference between the room temperature and the set temperature. (strong to low) to heat the room. Problems to be Solved by the Invention However, when the room is small, such a heating capacity control device may make the room feel cold and angry even when the room temperature reaches the set temperature. This is because when heating starts, especially when heating starts from a low temperature, the room is small and even if the indoor air temperature reaches the set temperature quickly, the walls, floor, ceiling, etc. in the room, which have a large heat capacity, are cold and do not warm up easily. This is because even if the room temperature reaches the set temperature, the temperature that humans actually feel becomes lower due to cold radiation. In addition, if the room was large, it could feel hot when the room temperature reached the set temperature. This was especially noticeable when the room temperature was relatively high at the start of heating. This is because when heating starts, the room air temperature rises slowly because the room is large, that is, the temperature rises almost in the same way as the walls, floors, ceilings, etc. in the room, which have a large heat capacity, or the temperature of the walls, floors, and ceilings that have a large heat capacity increases.
Because the temperature of the ceiling, etc. is high to a certain extent, even if the temperature rises a little slowly, by the time the indoor temperature reaches the set temperature, the walls, floor, and ceiling of the room will have a temperature almost the same as the indoor temperature, and cold radiation will be radiated from these. Since he was no longer exposed to it, he began to feel relatively hot. The present invention was made in view of these points, and an object of the present invention is to enable a comfortable heating state to be quickly obtained regardless of the size of the room or the temperature at the start of heating. Means for Solving the Problems In order to achieve the above object, the present invention provides a control section that sets the capacity of either the combustion amount or the hot air amount, or both, based on the Okayama force difference from the room temperature detection section and the room temperature setting section; a deviation calculation unit that calculates a room temperature change deviation from the room temperature at the start and the room temperature after heating start and after a fixed time; and a heating capacity instruction that outputs the room temperature, the room temperature change deviation, and the combustion amount or hot air amount variable means or both. a control rule storage unit that stores the relationship between the following as a control rule; a control inference unit that performs inference processing by referring to the room temperature and room temperature change deviation and the control rule in the control rule storage unit to determine the heating capacity instruction; and an output correction section that corrects the point in time at which the strong heating capacity instruction at the time of starting heating that is output from the control section is output based on the output from the inference section. Effects According to the present invention, with the above configuration, the larger the amount of change in room temperature and the smaller the heating load, that is, the smaller the room, the higher the point at which the maximum heating capacity is released at the start of heating, that is, the temperature is set. Therefore, the smaller the room, the higher the heating capacity will be until the temperature reaches the set temperature.As a result, even if there is cold radiation from walls, floors, ceilings, etc., the set temperature will reach the set temperature in a shorter period of time. Heating, that is, comfortable heating becomes possible. Also, when the room is large and the heating load is large, or when the room temperature is high when heating starts, the maximum heating capacity at the start of heating is canceled, that is, the temperature is set to a low value. Therefore, the larger the room and the higher the room temperature at the start of heating, the weaker the heating capacity will be from a temperature lower than the set temperature, and as a result, the room will not be overheated and heating will be more comfortable. EXAMPLE An example of the present invention will be described below with reference to the drawings. First, an example of a hot air heater will be explained using Fig. 1. 1 is the heater body, and 2 is a heat source provided inside the heater body 1, which vaporizes fuel and mixes it with combustion air. An evaporative burner is used to combust. 3 is a fuel pump that supplies fuel to the heat source section 2; 4 is a burner fan that supplies combustion air to the heat source section 2; 5 is a fuel pump that supplies combustion air to the heat source section 2; A convection fan 7 blows out hot air from the hot air outlet 6, and 7 is a louver provided at the hot air outlet 6 to change the blowing angle of the hot air, and a louver angle variable means 8 such as a stepping motor is used.
The louver angle is changed by Reference numeral 9 denotes a control device that drives the fuel pump 3, burner fan 4, and convection fan 5 to control the combustion amount and hot air amount, and in conjunction with this, drives the louver angle variable means 8 to change the louver angle. It is. FIG. 1 is a block diagram of the above control device, where 11 is a room temperature detection section, 12 is a room temperature setting section, and 13 is an input of the outputs from the room temperature detection and setting sections 11 and 12, and the combustion amount and temperature are determined by the output difference. The control section that sets the air volume drives the combustion amount variable means 14 made up of the fuel pump 3 and the burner fan 4, and the hot air amount variable means 15 made up of the convection fan 5. The controller is a deviation calculating section that calculates a room temperature change deviation En from the temperature T0 obtained from the room temperature detecting section 11 at the start of heating and the temperature T obtained after a certain period of time from the start of heating. Reference numeral 17 denotes a control rule storage unit that stores a control rule that describes the relationship between the temperature T0 at the start of heating and the room temperature change deviation En, and a heating capacity instruction to the output correction unit, which will be described later, using M control variables. . Here, an example of a control rule is ``If the room temperature is a little cold and the room temperature change deviation E
If n is large (condition part), the heating capacity instruction should be a little over (output part). Table 1 Here, the control variables such as ``slightly cold'', ``large'', or ``make it slightly overflow'' are defined by the membership function shown in FIG. Note that the control rule storage unit 17 includes a condition part storage unit 17a that stores the condition part of the control rule. If? and an output section storage section 17a that stores the output section of the II rule. Next, 18 is a control inference unit which calculates the room temperature T at the start of heating. Then, inference is made from the room temperature change deviation En and the control rule in the control rule storage section 17 to determine and output the heating capacity instruction amount. Here, the control inference unit 18 calculates the room temperature T at the start of heating from the room temperature detection unit 11, the deviation calculation unit 16, and the condition storage unit 17a.
o, a suitability calculation unit 18a that calculates the suitability of the room temperature change deviation En to the condition part of the control rule, and a weight that weights the output part of the control rule using the determined suitability and the output signal of the output unit storage unit 17b. The weighting is the calculation unit 18b, and the weighting is the calculation unit 18b.
It consists of a center-of-gravity calculation section 18c that calculates a heating capacity instruction from the output section of the control rule weighted from b.
Reference numeral 19 denotes an output correction unit that corrects the point in time when the strong heating capacity instruction from the control unit 13 is canceled based on the heating capacity instruction output from the control inference unit 18, and the corrected output is applied to the combustion amount variable unit 1.
4 and hot air volume variable means 15 to control these. The operation of the above configuration will be explained. First, when the start of operation is approved, the control section 13 starts combustion according to a predetermined program. Next, when combustion is started, the room temperature and set temperature are detected, and the amount of combustion is calculated based on the output difference between them, and the amount is outputted to the combustion amount variable means 14 and the hot air amount variable means 15 to control combustion and the amount of hot air. Normally, when heating starts, there is a large difference between the room temperature and the set temperature, so the system instructs to start heating at maximum heating capacity (maximum combustion/warm air volume). Further, at this point, there is no output from the control inference section 18, so the output correction section 19 outputs the output from the control section 13 as is, and starts heating at the maximum heating capacity. In the flowchart of FIG. 2, the operations are P1 to P. Next, when a certain period of time (for example, 15 minutes) has elapsed after the start of heating, the deviation calculation unit 16 calculates the room temperature change deviation En (En=T, To
). In the flowchart of FIG. 2, the operations are P, .about.P. Then, the fitness calculating section 18a calculates the above room temperature T0.
and the room temperature change deviation En are input into the condition section of the control rule in the condition section storage section 17a to obtain the degree of conformity W. In the flowchart of FIG. 2, it becomes pro. Next, the calculated degree of fitness W is weighted by the calculation unit 18b and is calculated on the output part of the control rule in the output part storage part 17b, which becomes P I+ in the flowchart of FIG. Next, the center of gravity calculation unit 18c synthesizes the functions of the output part of the weighted control rule and determines the center of gravity. This becomes the heating capacity instruction for the input room temperature T0 and room temperature change deviation En, and the obtained heating capacity instruction is output to the output correction section 19. This is P1□ of the flowchart in FIG. The output correction unit 19 adjusts the control unit 13 based on this heating capacity instruction.
This is given priority to the heating capacity instruction from the combustion amount variable means 1.
4 and the hot air volume variable means 15 to control them. That is, for example, if the room temperature at the start of heating is 3°C as shown in (A) in Figure 3, and the room temperature change deviation after a certain period of time is 10° as shown in (B) in the same figure, the heating capacity instruction is a in Table 1. A selection will be made from among the marks. Then, based on the table shown in Figure (C), inferences based on the Min-Max method and the center of gravity method are added, and the heating capacity instruction, in this case the point (temperature) at which strong heating capacity is released at the start of heating, is generally set. Instruct how many degrees to set the temperature or the temperature 1°C lower than the set temperature. Therefore, even if the strong heating ability release point (temperature) instructed by the control unit 13 is the set temperature, if the room is small or the room temperature is low when heating starts, the temperature will be ldeg, 2deg, etc. higher than the set temperature. Finally, if the room is large or the temperature at the start of heating is high, the temperature will be ldeg and 2 deg higher than the set temperature.
・The temperature becomes low. As a result, if the room is small and the room temperature is high at the start of heating, the high heating capacity will be used to heat the walls and floor until the temperature is higher than the set temperature. Even if there is cold radiation from the ceiling, etc., you will no longer feel cold. In addition, if the room is large or the temperature at the start of heating is high, the strong heating capacity will be canceled at a temperature lower than the set temperature and the heating capacity will change from medium to weak to weak, so the walls, floor, and ceiling will be heated. You will no longer feel hot due to the temperature rising too high. Effects of the Invention As is clear from the description of the embodiments, according to the present invention, when the room is small or the room temperature is low at the start of heating, heating is performed at a high heating capacity until the room temperature is a little high, so it is possible to heat the walls, floor, and ceiling. In addition, if the room is large or the room temperature is high when heating starts, the strong heating capacity can be turned off from a slightly lower temperature to provide medium to low heating. As the temperature increases, you will no longer feel hot when the room temperature reaches the set temperature. In other words, it is possible to perform optimal heating by determining the size of the room and the room temperature at the time heating starts, and it is possible to quickly and efficiently create a comfortable heating condition at the time heating starts.

Detailed Description of the Invention Field of Industrial Application The present invention relates to a heating capacity control device for hot air heaters and the like. 2. Description of the Related Art In general, this type of heating capacity temperature control device changes its heating capacity from strong to weak depending on the difference between a set temperature and the room temperature. Therefore, when starting heating when the room temperature is low, heating is started at the maximum (strong) heating capacity, and after the room temperature reaches the set temperature, heating at the maximum heating capacity is canceled and the heating capacity is determined by the difference between the room temperature and the set temperature. (strong to low) to heat the room. Problems to be Solved by the Invention However, when the room is small, such a heating capacity control device may make the room feel cold even when the room temperature reaches the set temperature. This is because when you start heating, especially when you start heating from a low temperature, the room will be warmed up, so even if the indoor air temperature quickly reaches the set temperature, the walls, floor, ceiling, etc. in the room, which have a large heat capacity, will be cold and will not warm up easily. This is because even if the room temperature reaches the set temperature, the temperature that humans actually feel becomes lower due to cold radiation. In addition, if the room was large, it could feel hot when the room temperature reached the set temperature. This was especially noticeable when the room temperature was relatively high when heating started. This is because when heating starts, the room air temperature rises slowly because the room is large, that is, the temperature rises almost the same as the walls, floor, ceiling, etc. in the room, which have a large heat capacity, or the temperature rises almost the same as the walls, floor, ceiling, etc., which have a large heat capacity.
Because the temperature of the ceiling, etc. is high to a certain extent, even if the temperature rises a little slowly, by the time the indoor temperature reaches the set temperature, the walls, floor, and ceiling of the room will have a temperature almost the same as the indoor temperature, and cold radiation will be radiated from these. Since he was no longer exposed to it, he felt relatively hot. The present invention was made in view of these points, and an object of the present invention is to enable a comfortable heating state to be quickly obtained regardless of the size of the room or the temperature at the start of heating. Means for Solving the Problems In order to achieve the above-mentioned objects, the present invention provides a control section that sets the capacity of either the combustion amount or the hot air amount, or both, based on the Okayama force from the room temperature detection section and the room temperature setting section; a deviation calculation unit that calculates a room temperature change deviation from the room temperature at the start and the room temperature after a fixed time period of heating start; and a strong heating capacity instruction at the time of heating start, which is output from the control unit based on the room temperature and the room temperature change deviation output. The control unit is configured with a capacity control unit that corrects the release output point, and another means for achieving the purpose is to adjust either the combustion volume or the hot air volume based on the Okayama force difference from the room temperature detection unit and the room temperature setting unit. Alternatively, a control unit that sets both capacities, a deviation calculation unit that calculates the room temperature change deviation from the room temperature at the start of heating and the room temperature after a certain period of time after the start of heating, and a control unit that calculates the room temperature change deviation from the room temperature at the start of heating and the room temperature after a certain period of time after the start of heating, and a a control rule storage unit that stores the relationship between the heating capacity instruction and the heating capacity instruction to be outputted to either or both of them as a control rule; The control inference unit is configured to include a control inference unit that determines an instruction, and an output correction unit that corrects the point in time when the strong heating capacity instruction at the time of starting heating that is output from the control unit is output based on the output from the control inference unit. be. Effects According to the present invention, with the above configuration, the larger the amount of change in room temperature and the smaller the heating load, that is, the smaller the room, the later the maximum heating capacity is released at the start of heating, that is, the temperature is set higher. Therefore, the smaller the room, the higher the heating capacity will be until the temperature reaches the set temperature.As a result, even if there is cold radiation from walls, floors, ceilings, etc., the set temperature will reach the set temperature in a shorter period of time. Heating, that is, comfortable heating becomes possible. Also, when the room is large and the heating load is large, or when the room temperature is high when heating starts, the maximum heating capacity is released earlier, that is, the temperature is set lower. Therefore, the larger the room and the higher the room temperature when heating starts, the weaker the heating capacity will be from a temperature lower than the set temperature, and as a result, the room will not be overheated and the heating will be more comfortable. . EXAMPLE An example of the present invention will be described below with reference to the drawings. 1 First, an example of a hot air heater will be explained using Fig. 6. 1 is the heater body, 2 is a heat source provided in the heater body 1, which vaporizes fuel and converts it into combustion air. A vaporizing burner is used to mix and burn the mixture. 3 is a fuel pump that supplies fuel to the heat source section 2; 4 is a burner fan that supplies combustion air to the heat source section 2; 6 is a burner fan that supplies combustion air to the heat source section 2; 6 is a pump that uses the heat of the combustion gas generated in the heat source section 2 as warm air to the front surface of the main body; A convection fan 7 blows out hot air from the hot air outlet 6, and 7 is a looper provided at the hot air outlet 6 to change the blowing angle of hot air, and the louver angle is changed by a lever angle variable means 8 such as a stepping motor. It is now possible to do so. 9
is a control device that drives the fuel pump 3, burner fan 4, and convection fan 6 to control the combustion amount and hot air amount, and in conjunction with this, drives the louver angle variable means 8 to change the louver angle. It is something. FIG. 1 is a block diagram of the above-mentioned control device, illustrating a case where inference control is performed as an example. In FIG. 1, 11 is a room temperature detection section, 12 is a room temperature setting section, and 13 is a control section that inputs the output from the room temperature detection and setting section 11.12 and sets the combustion amount and hot air amount according to the output. Said fuel pump3. The combustion amount variable means 14 made up of the burner fan 4 and the hot air amount variable means 16 made up of the convection fan 6 are driven. 16 is a deviation calculation unit which calculates the temperature To obtained from the room temperature detection unit 11 at the start of heating and the temperature T obtained after a certain period of time from the start of heating.
1, calculate the room temperature change deviation Xn. 17 is a control rule storage unit that stores the temperature To at the start of heating and the room temperature change deviation En.
A control rule is stored that describes the relationship between the heating capacity instruction to the output correction unit and the heating capacity instruction to the output correction unit, which will be described later, using control variables. Here, an example of a control rule is ``If the room temperature is a little cold and the room temperature change deviation En is large (condition part), the heating capacity instruction (the release point of the strong heating capacity instruction) should be slightly exceeded (output part).'' It is written in the if-them-format as shown in Table 1 below. Table 1 Here, the control variables such as ``slightly cold J'', ``large'', or ``make it slightly overflow'' are defined by the member shift function shown in FIG. The control rule storage section 17 includes a condition section storage section 1711 that stores the condition section of the control rule, and an output section storage section 17 that stores the output section of the control rule. Next, 18 is a control inference unit which calculates the room temperature T at the start of heating. Then, inference is made from the room temperature change deviation Kn and the control rule in the control rule storage section 17 to determine and output the heating capacity instruction amount. Here, the control inference unit 18 is a compatibility calculation unit that calculates the compatibility of the room temperature TO + room temperature change deviation En at the start of heating with the condition part of the control rule from the room temperature detection unit 11, the deviation calculation unit 16, and the condition part storage unit 171L. 18a, a weighting calculation unit 18b that weights the output part of the control rule using the obtained degree of conformance and the output signal of the output unit storage unit 17b, and a weighting calculation unit 18b that weights the output part of the control rule weighted from the calculation unit 18b. and a center-of-gravity calculation unit 180 that calculates a heating capacity instruction from the center of gravity by calculation of the center of gravity. Reference numeral 19 denotes an output correction unit that corrects the point in time when the strong heating capacity instruction from the control unit 13 is canceled based on the heating capacity instruction output from the control inference unit 18, and the corrected output is applied to the combustion amount variable means 14 and the hot air amount variable means. 15 to control these. Note that the control rule storage section 17, control inference section 18, and output correction section 19 constitute a capacity control section 19m that outputs a heating capacity instruction based on the room temperature To and the room temperature change deviation Kn. The operation of the above configuration will be explained. First, when the start of operation is confirmed, the control section 13 starts combustion according to a predetermined program. Next, when combustion is started, the room temperature and the set temperature are detected, and the combustion amount is calculated based on the pressure difference and outputted to the combustion amount variable means 14 and the hot air amount variable means 16 to control combustion and the amount of hot air. Normally, when heating starts, there is a large difference between the room temperature and the set temperature, so the system instructs to start heating at maximum heating capacity (maximum combustion/warm air volume). Further, at this point, since there is no output from the control inference section 18, the pressure correction section 19 accepts the output from the control section 13 as is, and starts heating at the maximum heating capacity. In the flowchart of FIG. 2, the operations are P1 to P6. Next, when a certain period of time (for example, 16 minutes) has elapsed after the start of heating, the deviation calculation unit 16 calculates the room temperature T at the time of starting heating. The room temperature change deviation ICn(E
Find n=T+To). In the flowchart of FIG. 2, the operations are shown in P7 to P9. Let the room temperature To at the time of heating start found here be to, and the temperature deviation be e. Next, the fitness computing section 18& stores the room temperature To: t and the temperature deviation 'Kn=e in the condition section of the turtle control rule in the condition section storage section 17 (the membership function M in Table 1 and FIG. 3, B
) to find the goodness of fit W. For example, a perpendicular line is drawn to to on the horizontal axis (room temperature) in FIG. Here, the fitness to the very cold function wt1, the fitness to the cold function wt2. The suitability for slightly cold weather is Wt3. Similarly to the above-mentioned room temperature, for the room temperature change deviation, the degree of conformity to a slightly wider function is We51, the degree of conformity to a normal function is W52, and the degree of conformity to a slightly narrower function is W63. When the above results are applied to Table 1 and organized, Table 2 becomes as shown. Actually, the smaller of the two (mln method) is used for the degree of fitness W. For example, if the magnitude relationship between the degree of suitability for cold weather Wt2 and the degree of suitability for normal weather W+52 is Wt2)WS12, then W
S2 is the degree of conformance to the membership function "slightly over" of the output part. In the flowchart of FIG. 2, it becomes Plo. Next, weighting is performed on the obtained degree of fitness W by referring to the pressure section (membership function C in Table 1.2 and FIG. 3) of the control rule in the output storage section 17b in the calculation section 1ab. conduct. Assume that the results are as shown in Table 3. In the flowchart of FIG. 2, this is Pll. (The following is a margin) ① (Everyone and 5 pieces) Next, the center of gravity calculation unit 180 synthesizes the functions of the output part of the weighted control rules (MAX method) and finds the center of gravity (center of gravity method). This becomes the heating capacity instruction for the input room temperature To and room temperature change deviation Kn at the time of heating start, and the obtained heating capacity instruction is output to the output correction section 19. P12 of the flowchart in FIG. It is PI3. The results are shown in Figure 4. The output correction unit 19 adjusts the control unit 13 based on this heating capacity instruction.
This is given priority to the heating capacity instruction from the combustion amount variable means 1.
4 and the hot air volume variable means 16 to control these. That is, for example, the room temperature at the start of heating is 7° as shown in Figure 3.
In C, the room temperature change deviation after a certain period of time is 1 as shown in the same figure (B).
If it is 1 degree, the heating capacity instruction, in this case, the point at which the strong heating capacity at the start of heating is canceled is set 1.2 degrees higher than the set temperature by performing a series of calculations. If the room temperature change deviation is the same, the room temperature will decrease as is clear from the control rules in Table 1 (normal → slightly cold → cold → very cold).
Accordingly, there is a rule that the room temperature becomes higher than the set temperature (overshoots), and the above-mentioned tendency is the same (the degree is different) regardless of the size of the room temperature change deviation. Also, if the room temperature is the same, the rule is that the release point for strong heating capacity is set higher than the set temperature as the room temperature change deviation increases (small → normal → slightly large - large), and this tendency applies regardless of the room temperature at the start of heating. There is a similar tendency (to a different degree). In this way, the point at which the strong heating ability is released for the set temperature is determined continuously while maintaining the above control rule with respect to changes in the initial room temperature at the start of heating and the room temperature change deviation. Therefore, even if the temperature at which the strong heating ability is turned off (instructed by the control unit 13) is the set temperature, if the room is small or the room temperature is low when heating is started, the temperature may be 1 level lower than the set temperature.
cieg, 2 deg... If the temperature is high, conversely, if the room is large or the temperature at the start of heating is high, the temperature will be 1d6g, 2 (16g...lower than the set temperature.As a result, the room will be small) When the room temperature is low at the start of heating, heating is performed at high heating capacity until the temperature is higher than the set temperature, so even if there is cold radiation from walls, floors, ceilings, etc., you will not feel cold. Also, the room is big.
When the temperature at the start of heating is high, the strong heating capacity is canceled when the temperature is lower than the set temperature and the heating capacity changes from medium to low to weak, causing the temperature of the walls, floor, and ceiling to rise too much. You will no longer feel hot. Effects of the Invention As is clear from the description of the embodiments, according to the present invention, when the room is small or the room temperature is low at the start of heating, heating is performed at a high heating capacity until the room temperature is a little high, so it is possible to heat the walls, floor, and ceiling. In addition, if the room is large or the room temperature is high when heating starts, the strong heating capacity can be turned off from a slightly lower temperature to provide medium to low heating. As the temperature changes, you will no longer feel hot when the room temperature reaches the set temperature. In other words, it is possible to perform optimal heating by determining the size of the room and the room temperature at the time heating starts, and it is possible to quickly and efficiently create a comfortable heating condition at the time heating starts.
