The degree of occlusion; and the first correcting mechanism 'corrects the target rotation number of the fan set by the target rotation number setting device in cooperation with the occlusion degree of the air passage measured by the occlusion degree measurement mechanism. < Known technology > If the above-mentioned combustion device is used, the target rotation number of the fan is set according to the target rotation number setting device in combination with the necessary combustion amount of the burner. In addition, the amount of power supplied to the fan is controlled by the power supply control mechanism so that the number of rotations of the fan measured by the number-of-rotations measurement unit coincides with the target number. According to this, generally, the number of rotations of the fan is equal to the target number of rotations, and the combustion air is supplied to the burner in an amount corresponding to the amount of combustion, so that the complete combustion state of the burner can be maintained. However, even if it is controlled so that the number of rotations of the fan is equal to the target number of rotations', since foreign matter is mixed in the ventilation path to form an occluded odor, air in the ventilation path is trapped, so that combustion air cannot be supplied to match the amount of combustion of the burner.

Description of the invention (2 ----- (Please read the notes on the back before filling this page) Occlusion Degree The increase of the fan reduces the load of the fan, so even if the number of fan rotations is maintained constant, the so-called blocking degree can be measured using the so-called property of fan power reduction. More specifically, when the number of fan rotations is maintained constant, the power supply control mechanism is used. The degree of blockage of the air passage is measured in accordance with the change in the electric power considered to be supplied to the fan. Furthermore, as the measured degree of blockage is increased, the correction target rotation number is increased by the t-th correction mechanism. In addition, the fan is controlled by the fan control device The number of rotations of the burner is made equal to the new target rotation number that is increased and corrected. Accordingly, the supply of combustion air to the burner is compensated because the blockage of the air passage is reduced, and the complete combustion of the burner can be maintained. < Problems to be Solved by the Invention > --T— However, the degree of occlusion of the ventilation path gradually increases. Even with this, the target rotation number is gradually increased and corrected. There is a limit to the amount of power supplied to the fan, so the number of fan rotations must not increase above this, and it may eventually be saturated before reaching the target number of rotations. For this reason, the power supply control mechanism is considered to supply the fan power to the fan, The deviation of the actual fan power supply increases, and the occlusion degree of the ventilation path measured by the occlusion degree control device may sometimes become incorrect. In this case, the ^ tube combustion air is insufficient, but in the end according to the target rotation number of the first correction mechanism instead Reduce the correction, so it is possible to improve the incomplete combustion of the burner. Here, the present invention provides a combustion device capable of suppressing the incomplete combustion of H as the power supply to the fan is saturated as a solution problem. < Means for Solving the Problems > In order to solve the aforementioned problems, the combustion device of the present invention includes a method for judging that the paper size is applicable to the Chinese National Standard (CNS) A4 specification (2) 0X297 public love). 5.

First: Reduce the upper limit of the target rotation number of the fan corrected by the correction s / positive mechanism until it is determined that the power supply amount can be increased. According to the present invention, it is impossible to increase the upper limit of the target rotation number of the correction fan at least until the fan can be increased. Therefore, when the target rotation number of the fan is increased and corrected, the rotation number of the fan is set to the appropriate target rotation number to ensure that the control can be increased. In other words, because it is impossible to increase the power supply to the fan (limited to the degree of occlusion of the ventilation path is not reduced) 'Although the number of rotations of the fan must not be increased more than this, increase the number of correction target rotations' can avoid seeking the rotation of the fan The number of cases increased. In this way, "if according to the present invention", the incomplete combustion of the burner can be suppressed by the amount of power supplied to the fan due to saturation. In addition, in the present invention, when the number of rotations of the fan measured by the rotation number measuring mechanism is constant, the occlusion degree measuring mechanism measures the above-mentioned fan power based on the fan power deemed to be supplied to the fan by the power supply control mechanism. Occlusion of the ventilation path. According to the present invention, as described above, since the power supply amount of the fan is corrected to be within a controllable range due to the correction of the target rotation number, the fan power that is considered to be supplied to the fan by the power supply control mechanism can avoid the deviation from the actual fan power. Happening. In addition, the occlusion degree of the air passage can be accurately measured by the occlusion degree measurement mechanism. Further, the target rotation number of the fan, which should be corrected according to the degree of occlusion, is set to a complete combustion chamber that can be supplied to the burner. 6 This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm). 576908 5. Description of the invention (4 The necessary combustion air. In addition, it can be burned. The complete mechanism for maintaining the burner is busy. There is a third correction mechanism. The third correction == the judgment mechanism judges that it can be judged by the foregoing. After the power supply control mechanism detects a large power supply amount, it is determined that the power supply amount cannot be increased until it is increased. 'Increase the upper limit of the number of revolutions by increasing the number of fans corrected by the first correction mechanism. According to the present invention, when the power supply amount to the fan can be increased, the upper limit value of the target rotation number of the correction fan is increased until it is impossible to increase. Therefore, the 'fan ❸ target rotation number is increased and corrected to the fan. Power supply: No: it can increase to the limits above them, and the number of fan rotations is: When the target number of rotations can ensure that the state of control can be increased to the maximum. In addition, this The invention further includes a combustion control mechanism for reducing the upper limit value of the target combustion amount of the burner when the upper limit value of the target rotation number of the fan is reduced and corrected by the second correction mechanism. Further, the present invention It further includes a combustion control mechanism that reduces the upper limit value of the target combustion amount of the burner when the upper limit value of the target rotation number of the fan is reduced by the second correction mechanism, and reduces the upper limit value of the target combustion amount of the burner. When the upper limit value of the target rotation number is increased by the third correction mechanism, the upper limit value of the target combustion amount of the burner is increased. According to the present invention, in view of the rotation number of the fan or the supply amount of combustion air, The upper limit value of the burner is set to be too large at the end, so that it is possible to surely prevent the lack of combustion air from forming a burner's poor combustion conditions.

If it is determined to be too large, it is determined to be correct. According to the present invention, the output level of the power supply circuit is initially set to be high for the output level of the fan, but as the difference between the two output levels is reduced, the so-called power supply capacity of the power supply circuit is reduced.

The rotation number measuring mechanism 51 measures the rotation number of the fan 3. The target rotation number setting split 52 is to set the target rotation number of the fan 3 by the combustion control mechanism 58 in accordance with the set required combustion amount of the burner 2. The power supply control mechanism 53 controls the amount of power supplied to the fan 3 so that the number of rotations of the fan 3 coincides with the target number of revolutions. The occlusion degree measuring mechanism 54 measures the degree of occlusion of the air passage from the combustion chamber 1 to the exhaust port 12 when the number of fan rotations is controlled to a certain level by using the power supply control mechanism 53 based on the recognized fan power supplied to the fan 3.

Description of the invention (10) Ground output; The smoothing circuit 74 is the output of the switching circuit 73 Smooth the supply to the fan. The pulse circuit 72 is constituted by using a target rotation number signal output circuit 721, a fan current detection circuit 722, an OP amplifier (the "certain circuit" of the present invention), an oscillation circuit 724, a comparison circuit 725, and a FET driving circuit 726. The switching circuit 73 is configured using a FET731. The target rotation number signal output circuit 721 outputs a DC target rotation number signal corresponding to the level at which the target rotation number is set by the target rotation number setting means 52. The fan current detection circuit 722 outputs a signal corresponding to the level of the current flowing to the fan 3. The OP amplifier 723 outputs a level signal corresponding to the deviation of the target rotation number signal output from the target rotation number signal output circuit 721 and the target rotation number signal of the signal output by the wind current detection circuit 722. The oscillation circuit 724 outputs a triangular wave signal (waveform signal) with a certain peak value at a certain period. The comparison circuit 725 is an input signal of the OP amplifier 723 and an output signal of the oscillation circuit 724, and outputs a pulse signal having a duty factor corresponding to the level of the signal output from the OP amplifier 723.

Description of the invention (11) Rotation number measurement mechanism 5 1 includes output The fan rotation number circuit 51, which corresponds to the signal of the actual rotation number of the fan 3. The operation of the combustion device having the aforementioned structure will be described with reference to FIG. 3. First, the combustion (si) of the burner 2 is started. Specifically, in the remote controller 6, the target combustion amount of the burner 2 for supplying warm water to the set hot water supply temperature is set by the combustion control mechanism 58. The target rotation number setting device 52 sets the target rotation number of the fan 3 based on the target combustion amount. Further, the combustion control mechanism 58 controls the gas supply amount from the gas passage 21 to the burner 2 by the rotation number measuring mechanism 51 in response to the energization amount of the rotary numerical control regulator proportional solenoid valve 212 measured by the fan 3. The gas supplied to the burner 2 is ignited by the igniter 23 through the ignition electrode 22, and the burner 2 is supplied by the fan 3 with combustion air for combustion. In addition, the 'occlusion degree measuring mechanism 54 measures the degree of occlusion of the air passage in response to changes in the accumulation of dust and the like of the heat sink 422 of the heat exchanger 421. When the degree of occlusion of the air passage increases, when the degree of occlusion increases, the load on the fan 3 decreases, and even if the number of fan rotations is constant, it is possible to measure the property that the so-called power supply to the fan 3 decreases. More specifically, when the number of fan rotations is maintained constant, the power supply control mechanism 53 can measure the degree of blockage of the air passage according to the increase or decrease of the fan power supplied to the fan 3 as recognized. Further, the first correction mechanism 55 increases the measured occlusion degree by the occlusion degree control device 54 and corrects the target rotation number as the occlusion degree control device 54 increases. The power corresponding to the target number of rotations that has been increased and corrected is supplied to the fan 3 by the power supply control mechanism 53. The number of rotations of the fan 3 is controlled to coincide with the target number of rotations. In addition, 'the increase in the degree of occlusion of the ventilation path compensates for the reduction of the combustion air, and maintains this paper standard to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) 14 -------------- --- Order --------------- (Please read the precautions on the back before filling out this page) V. Description of the invention (2) Complete combustion state of combustion state 2. In addition, the judging means 56 judges whether or not the power supply amount to the fan 3 can be increased based on the following circuit characteristics (s2). That is, the DC signal output from the power supply circuit ^ is supplied to the fan 3 when it is supplied to the flat α circuit 74 by using ON / 0FF of the switching circuit 73 as a pulse signal. Therefore, the amount of power supplied to the fan 3 can be increased by increasing the duty factor of the pulse signal, but it cannot be increased after the duty factor reaches 1 ". In addition, the duty factor of the pulse signal from the switching circuit 73 is the same as the duty factor of the pulse signal given to the switching circuit by the pulse circuit 73. For this reason, the duty factor of the pulse signal generated by the pulse circuit reaches "丨" After that, it becomes impossible to increase the amount of power supplied to the fan 3. Further, the duty factor of the pulse signal generated by the pulse circuit 72 is oscillated by the oscillating circuit 724 over a period of the triangular wave signal level, which coincides with the time ratio below the level of the signal output by the OP amplifier 723. Therefore, when the peak value of the triangular wave signal oscillated by the oscillating circuit 724 becomes lower than the level of the output signal of the OP amplifier, it is impossible to increase the power supply i to the fan 3. In addition, when the peak value (VI) of the triangular wave signal oscillated by the oscillating circuit becomes lower than the level of the output signal of the OP amplifier 723, the output of the comparison circuit 561 constituting the judgment circuit 56 is lower than this. For this reason, the judging means 56 can judge whether the power supply amount to the fan 3 can be increased based on whether the output from the comparison circuit 561 has decreased in the judging circuit 56. The degree of occlusion of the ventilation path is gradually increased, the target rotation number is gradually increased and corrected, and the power supply amount to the fan 3 is also gradually increased. In addition, if the power supply to the fan 3 cannot be increased by the judging mechanism 56 (at 576908 A7 ____B7 1 丨 _ 丨 __ 丨 ·--_ V. Description of the Invention (I3) s2 is YES), the second The correction mechanism 571 reduces the upper limit of the number of target rotations to be corrected by the first correction mechanism 55 (s3). At this time, the combustion control mechanism% cooperates with the second correction mechanism 571 to reduce the target rotation number of the correction, thereby reducing the upper limit value of the target combustion amount of the correction burner 2. Next, the 'judgment mechanism 56 judges whether the power supply amount to the fan 3 can be increased (s 4). When the determination unit 56 determines that it is impossible to increase the power supply to the fan 3 (NO at s4), the second correction unit 271 continues to use the first correction unit 55 to reduce the upper limit of the number of target rotations to be corrected. (S3). On the other hand, when the determination unit 56 determines that it is possible to increase the power supply to the fan 3 (YES at s4), the third correction unit 572 increases the target rotation number corrected by the first correction unit 55. Limit (s5). At this time, the combustion control mechanism 58 increases the upper limit value of the target combustion amount of the burner 2 by the third correction mechanism 572 in cooperation with the reduced target rotation number. Then, the amount of power supplied to the fan 3 is increased to a possible limit (NO at 56), and the upper limit of the correction target rotation number is continued to increase (see S4, 5). According to the combustion device (hot water supply device) according to this embodiment, it is impossible to increase the amount of power supplied to the fan 3, and then to reduce the upper limit of the target rotation number of the fan 3 at least until it can be increased (see Figure 3 s2 to 4). Therefore, when the target rotation number of the fan 3 is increased and corrected, the rotation number of the fan 3 is set to the current target rotation number to ensure that the control can be increased. In other words, since it is impossible to increase the power supply to the fan 3 (limited to the fact that the degree of occlusion of the ventilation path is not reduced), although the number of rotations of the fan 3 must not be increased more than this, the number of correction target rotations is increased, which can avoid seeking a fan Increasing the number of rotations of 3. In this way, the power supply to the fan 3 is accompanied by the saturation. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -16

Description of the invention (14)-The quantity can suppress the incomplete combustion of the burner 2. In addition, the second correction mechanism 571 and the third correction mechanism 572 correct the target rotation number to the amount of power supplied to the fan 3 within a controllable range. Thereby, it is possible to avoid the deviation between the fan power supplied to the fan 3 by the known power supply control mechanism 53 and the actual fan power. That is, by using the occlusion degree measuring mechanism 54 < the relationship between the number of fan power revolutions corresponding to the corrected target number of revolutions, the deviation can be avoided from the actual relation. In addition, the degree of occlusion of the air passage can be accurately measured by the degree of occlusion measuring mechanism 54. Further, the target rotation number of the fan 3 corresponding to the occlusion degree correction is set to be sufficient to supply the combustion air necessary for the complete combustion of the burner 2. In addition, the complete combustion state of the burner 2 can be reliably maintained. In addition, when it is possible to increase the power supply amount to the fan 3, increase the upper limit value of the target rotation number of the correction fan 3 until it is impossible to increase it (refer to Figs. 3 to 6). Therefore, the target rotation number of the fan 3 is increased and corrected to a limit where the power supply to the fan 3 cannot be increased above them, and the control of the rotation number of the fan 3 to the target rotation number can ensure that the control can be increased. The state is at its maximum. Further, when the upper limit value of the target rotation number of the fan 3 is reduced by the first correction mechanism 571, the upper limit value of the target combustion amount of the burner 2 is reduced and corrected by the combustion control mechanism 58. When the upper limit value of the target rotation number of the fan 3 is increased by the second correction mechanism 572, the upper limit value of the target combustion limit of the burner 2 is increased and corrected by the combustion control mechanism 58. Therefore, in view of the number of rotations of the fan 3 or the upper limit of the supply amount of the combustion air, the target combustion amount of the burner 2 is finally set too large. As a result, the combustion air is insufficient, and the Chinese national standard (CNS ) A4 specification (210X297 public love) 17 orders (please read the precautions on the back before filling this page) 576908 V. Description of the invention (l5 to prevent the burner 2 from becoming incompletely burned. Also, in this implementation In the form, based on whether the pulse circuit 72 can output pulse signals to the switching circuit, it can be determined whether the power supply to the fan 3 can be increased. However, as the output level of the power supply circuit 7m in other embodiments, whether it is better than the smoothing circuit 74 The output level of the fan 3 is higher than a positioning level, and it is also possible to judge whether it is possible to increase the power supply to the fan 3. If according to other applicable embodiments, the output level of the “from the power circuit” is initially set to be compared with that of the fan 3. The output level is high, but as the difference between the two rounds of output levels narrows, it can be judged that No. Increase the power supply to the fan 3. The "-疋 level" here means that when the rectification is performed according to the switching circuit 73, the output signal from the power circuit 7! Is not intermittently and continuously supplied to The fan ', however, in the figure passes through the smoothing circuit 74, so the level of the output should be reduced. In addition, the circuit is not rectified by the exchange circuit, and the power supply to the fan 3 by the power circuit 71 cannot increase. To the upper limit. Therefore, 'When the difference between the two output levels is reduced to & below the _ positioning level, it can be judged that it is impossible to increase the power supply amount to the fan 3. Furthermore, depending on whether the power supply amount to the fan 3 is possible For the judgment of increase, the upper limit value of the target rotation number of the fan 3 is reduced by the second correction mechanism "Buco *", so that the amount of power supply to the fan 3 can be reduced and corrected until it can be increased (see Fig. S2 to s4). The upper limit of the target rotation number of the fan 3 can be adjusted by the first ground positive mechanism 572 to increase the power supply to the fan 3 until the limit can be increased (see s4 to s6 in Fig. 3). Furthermore, the combustion control mechanism can be used. Due to The target burning amount of the fan 3 with the revised upper limit is set to 58 pages. The paper size is adapted to the Chinese National Standard (CNS) A4 specification (210X297 mm) 576908 A7 ______B7 V. Description of the invention (M, ~~ -The upper limit of the target combustion amount of the state 2. Therefore, "the number of rotations of the fan 3 or the upper limit of the supply amount of combustion air, the target combustion amount of the burner 2 is eventually set to be too large" Insufficient air can prevent the burner 2 from becoming incompletely burned. <Simple description of the drawing> Fig. 1 is an explanatory diagram of the structure of the combustion device of the embodiment.
