INSTRUCTIONS: [Technical Field of the Invention] The present invention relates to a forced exhaust type water heater, and particularly relates to a control method for improving the combustion performance and safety of a water heater. [Prior Art] The types of gas water heaters commonly available on the market can be classified into RF (outdoor setting), CF (natural exhaust), and FE (forced exhaust). Among them, the "outdoor-only" RF type, because there is no exhaust facility, "must" the device is in a completely open space. The CF type of "natural exhaust" relies on the natural pressure generated by hot air to discharge carbon monoxide. As for the FE type of "fan forced exhaust", the direct fan of the water heater can forcibly extract the exhaust gas. The above-mentioned "fan forced exhaust" ρΕ type water heater can provide an active guiding airflow to discharge the hot water 拙 combustion exhaust gas to prevent incomplete combustion or residual gas explosion and leakage. % As shown in October 21, 2005, Taiwan Patent No. 27886ι "Teaching Water Cries Forced Drainage Control Structure" has been described by using a blower to provide active guidance to the gas water heater (4). The towel detection unit speculates that the blower provides sufficient wind pressure, and then performs the airflow under the guiding airflow. 'It is inevitable that there is a general wind pressure detecting unit (device) when it is used. 200825346 = blowing, heat The leeches of the water rafts, which cause the winds to make the wind turbines operate, do not humiliate the 'into (four) sound reduction unit system' and lose the wrong letter of dreams, generate water heater control unit malfunction. Moreover, the cost of the market is also high, which is where there is room for improvement. The invention is a method for improving the combustion performance and safety of the water heater. The proportional valve current is sent to "correspond to the corridor and the current to determine whether the external environment has a large wind 2". County, the whole motor speed 'Nove _ water in the ignition, high, the introduction of gas can be properly mixed with the air, up to i 22. H conditions, good surface conditions, to face the leader The forced exhaust type water heater provided according to the present invention comprises an ignition control machine. Ignition: 2 units, exhaust control unit, detection unit and Wei's system for the control of the ignition control unit. Heart (4)^气==== Water is connected to the detection unit' When the gas is burned, the detection unit will detect the motor running::r signal one motor3: wind control unit will According to the side signal wire, it can be judged whether the speed of the motor running of the blower can be adjusted. Step by step: send the speed of 200825346, so that the exhaust gas emission can reach at least the acceptable range. In addition, the exhaust control unit will be based on the detection. Test signal coming Whether the horse current is less than the over-the-air mosquito value, whether the mosquito fan can increase the rotational speed through the compensated material, so that the motor current can be higher than the abnormal actuation critical line. Finally, the motor current is lower than the abnormal actuation threshold. In this case, according to whether the motor current can be pulled back above the abnormal actuation threshold, it is judged whether it is necessary to stop the combustion of gas and stop the supply of gas to ensure the safety of the user. 'Embodiment】 Please refer to the first figure It is the main function block diagram of the forced exhaust type water heater of the present invention. The c〇mpuls〇ry exhaust hot-water-heater 1 includes an ignition control unit (igniti〇n control unit) 10. A water injecti unit (2), an exhaust control unit 30, a detection unit 40 and an air_extractjng apparatus 50. The forced exhaust water heater Connected to a water supply unit 2 for supplying the forced discharge type water heater 1 heated by the water supply unit 2 The water supply unit 20 is connected to the ignition control unit 1A. When the user opens the water supply unit 2 connected to the forced discharge type water heater 1, the water supply unit 20 automatically introduces the unheated cold water into the forced discharge. In the water heater 1, the amount of water in the forced helium gas water heater 1 is detected to generate a water quantity signal to the ignition control unit 1. The ignition control unit 10 is coupled to the exhaust control unit 30, When the ignition control 200825346 unit 10 knows that sufficient water is introduced into the forced exhaust type water heater 1, there is no abnormal condition in the forced exhaust type water heater 1, for example, the exhaust vent is not blocked, and the forced exhaust type water heater 丨When the wind pressure is normal or the like, gas is introduced to further perform an ignition process, and the cold water introduced into the forced exhaust type water heater 1 is heated to supply hot water to the water supply unit 2. In addition, while the water supply unit 20 is provided with the water quantity detecting signal to the ignition control unit 10, the ignition control unit 10 transmits an exhaust signal to the exhaust control unit 30. The exhaust control unit 30 is coupled to the blower 50. And the detecting unit 40, the detecting unit 40 is coupled to the blower 50. When the ignition control unit 1 uses the exhaust control signal to drive the motor of the blower 50, the blower 50 actively directs the airflow to exhaust the exhaust gas burned in the forced exhaust water heater i. While the blower 50 motor is running, the detecting unit 4〇 can measure the rotational speed of the motor operation and the motor current Im of the blower at any time to generate a debt measurement signal to the exhaust control unit 3〇, so that the exhaust control unit 3 can be ready at any time. Monitor the operation of the blower 50 motor. In addition, the exhaust control unit 3 determines whether the efficiency of the blower 5 〇 exhausting the combustion exhaust gas is normal according to the result of the detection signal, to determine whether to increase the motor speed or reduce the motor speed, or to control the ignition control unit 1 to stop the ignition and combustion gas. . However, when the exhaust port of the forced exhaust type water heater 1 is obstructed, or the wind pressure outside the forced exhaust type hot water crying 1 is too large, the rotation speed of the blower 5 〇 motor will be lower and the motor current Im will also be The reduction is caused, so that the exhaust gas burned by the ignition control unit 1〇 cannot be smoothly discharged. Therefore, the present invention utilizes the physical characteristics of the above-mentioned motor to propose a control method for the combustion performance and safety of the water heater. Please refer to the second diagram and the second diagram of 200825346 to illustrate the use of the exhaust control unit 30 to monitor the operation of the blower 50 motor. In the case of the ignition control unit 1 (), the operation of the ignition control unit 1 () is prevented to prevent the exhaust gas from being smoothly discharged due to the obstruction of the exhaust port or excessive wind pressure. The second figure is the corresponding waveform diagram of the proportional valve current and the motor current of the forced exhaust type water heater of the present invention, and the third figure is the forced exhaust type hot water of the inner valley of the invention to perform the combustion performance of the lifting water heater and Flow chart of the control method of safety. In the second figure, the corresponding waveform diagram of the proportional valve current and the motor current is divided into four parts, namely a normal actuation zone ^, a control actuation zone n and an abnormal actuation zone]. When the forced venting hot water 1 operates on the normal operating threshold c, it indicates that the forced venting water heater 1 is outside the windless state, or the exhaust vent of the forced venting water heater 1 is not blocked, so Under this ideal condition, the combustion exhaust gas generated by the forced exhaust type water heater i burning gas can be smoothly discharged without any hindrance. " When the forced venting water heater 1 operates in the normal operating zone + I, the external venting water heater i is in a windy state but weak, 'or ^ the venting port of the vented water heater 1 is slightly blocked, so at this time The strong, hot water & 1 gas produced by the combustion of the pure shaft in the discharge of a point of resistance, but the performance of the exhaust gas is still unaffected, does not affect the proportion of gas and air mixing. When the forced venting water heater 1 operates in the control actuation zone 2, it means that [the H-type hot water n 1 system is in a state of verification but (4), or the exhaust vent of the forced venting m 1 is subjected to a larger _ plug, @ At this time, the combustion exhaust gas generated by the forced exhaust water heater 1 burning gas is subjected to Zheng s at the time of discharge, but the performance of the working money is still within an acceptable range, and the proportion of gas in 200825346 is slightly higher. When the forced exhaust type water heater 1 operates in the abnormal operating area m, it indicates that the forced exhaust type water heater 1 is in an over-pressure state, or the exhaust port of the forced discharge water heater 1 is severely blocked, so the forced exhaust heat at this time The combustion exhaust gas produced by the water-burning gas of Shuiyi 1 was severely blocked during discharge, and exceeded the design standard in the performance of exhausting combustion exhaust gas, and even seriously affected the proportion of gas mixed with air. In the third figure, when the forced venting water heater 1 discharges the combustion hot gas generated by the burning gas, the steps of monitoring the operation state of the blower 50 are as follows: First, when the user turns on the water supply unit 2, the water supply unit 20 automatically will not The heated cold water is introduced into the forced exhaust type water heater 1, and the amount of water introduced into the forced exhaust type water heater 1 is sold to generate a water amount spread signal to the ignition control unit 1〇. When the ignition control unit 10 knows that the amount of water is enough to be introduced into the forced exhaust water heater, a row of air signals is transmitted to the exhaust control unit 30, so that the exhaust control unit 30 drives the air supply t 50 motor. . Wherein, when the motor is running, the detecting unit 40 continuously detects the running speed of the motor and the motor current Im, and transmits the detection & number back to the exhaust control unit 30 to further determine the running condition of the motor, such as S210. After receiving the feedback of the tears, the detection unit 4 determines whether the motor current Im of the motor is equal to the abnormal operating threshold, as in step S22. Among them, the abnormal operation critical signal is the proportional valve current and motor current corresponding value on the abnormal boundary line A^

The control actuation threshold is the corresponding value of the proportional valve current and the motor current Im on the control critical line B. When the motor current Im is greater than the abnormal actuation threshold and less than the control threshold, it indicates that the operation of the current blower 5〇 is maintained in the control zone η, so the exhaust control unit 30 does not correct the blower 5 'And returning to step S210, the motor current Im reaching the blower 50 4 is detected by the detecting unit 4Q. When the motor current im is not only greater than the inner limit value and greater than the control actuation threshold value, it indicates that the current operation of the blower 保持 is maintained in the normal actuation zone z, so it is determined whether the rotational speed adjustment value of the whole motor speed is further determined.

Will return to the step _^^^ § The motor current Im of the marriage is still cutting the control limit value N·, indicating that the operation of the blower 50 will return to the normal operation in the normal state = 30, and determine whether the second speed adjustment value is 〇, and repeat steps S235, S245 ^ action ' until the motor current Im is less than the control actuation threshold 3 operation is in the control actuation zone E 'even in the control of the sergeant, according to step S22G, when the motor current Inv is less than the same f The critical value is not that the operation of the blower 50 is maintained in the abnormal operation zone. The exhaust control unit 30 will determine whether the rotational speed of the motor has been reached according to the return of the detection unit 4, and the motor is operated. The highest limit speed of operation, as in step S23. When the speed of the motor has reached the maximum speed, the operation has reached the limit, but the ignition control unit is still in the air; d: the fan 50 smoothly discharges all the exhaust gas generated by the combustion into the field. Determine if the motor current is small or not, as in step §233. ^ When the motor running speed has reached the maximum speed, and the horse's + is greater than the over-wind pressure setting value, 'this indicates that the forced spelling 1 at this time still has the opportunity to pass the compensation method, and the blower 5〇 祚2/,,, 7 control the actuation zone π, thus forcing the operation of the vented water heater i to step S210, the exhaust control unit 30 will continue to drive the blower to ignite the combustion exhaust gas generated by the ignition of the a 1G gas = forced exhaust Water heater 1 outside, and measure the blower 2 1 ~ day 9 motor power 12 200825346 :=t. The speed of the motor running has not reached the maximum speed, and the motor is electric, and when the L Im is less than the set value of the over-pressure, the exhaust hot water H 1 can not be pulled back to the control actuation area by the strong method of compensation. When, therefore, the second transport unit 10 stops burning gas and blocks the gas _= according to step S23 〇, when the motor running speed is still: the speed used to adjust the motor speed ^ reaches the upper limit (that is, the motor speed setting can be adjusted) ^Whether the air control fresh element 30 can control the lifting blower ^) = catch, to compensate the blower 50's ability to discharge the combustion exhaust gas, such as the step ^ 2 centimeter has reached the value, not only indicates that the forced exhaust hot water 'large, or Forced discharge _ water heater 1 exhaust wind b and resistance, and even the current forced exhaust fan 5. The discharge of the combustion exhaust gas can be used to control the ignition control unit 1G to stop the service gas and supply the gas, as in step S243. When the speed adjustment value has not reached the above 2, although the external exhaust pressure of the forced exhaust water heater i may be too large, or the gas type, 1... the exhaust vent may be blocked, but the current strong gas ΐΪ hot water ^ 1 can still compensate the blower 5G discharges the combustion waste=, force, so the exhaust control unit 3G will step-by-step control of the blower 5〇=the speed of the lifting operation' and measure the value of the motor"丨L 随时 through the detecting unit 4〇4 at any time, as in step S25〇 . Finally, the exhaust control unit 30 further determines whether the horse=current after the lifting speed is still less than the abnormal operating threshold, as in step S26. When the adjusted motor current is still less than the abnormal operating threshold, return to step 13 200825346 S230' until the above-mentioned step threshold is repeated until the motor current is raised to be greater than the abnormality to return to the control actuation. The motor must be operated by the abnormality. When the operating area is moving, the adjusted motor current is greater than the abnormality. The operation is activated. The operation of the second zone: 1 has been operated by the abnormal operating zone. The operation of the _ Π Π Π 式 热水器Go back to the step-by-step water crying gas and repeat the above steps to ensure that the forced excavation:, Shui Yi 1 emits the ability to burn exhaust gas. The forced venting water heater 1 produced by Sri Lanka can know that in the step of monitoring the exhaust gas of the exhaust gas, if the forced discharge ====burning waste, the gas and the air _ r- TT U〒, especially When the normal operating zone J and the control "plus" and the normal operating threshold of the boundary line, not only the exhaust condition of the U crane, but also the electricity consumed by the motor operation can be saved, and the gas of the money 1_(10) can be combined with the air. Appropriate combustion conditions are also met to ensure good combustion conditions, that is, to maintain high touch and low values. "Shiben ♦ Day (10) provides the advantage that the exhaust fan in the exhaust combustion encounters the wind pressure is too large or the exhaust vent is blocked, the motor current and the motor transport will decline the physical characteristics to determine the forced venting hot water. Whether the external wind pressure is too large or not, and whether the exhaust port is blocked, it is judged whether the forced exhaust type hot water can discharge the combustion exhaust gas normally. Another advantage provided by the present invention is that the reference value corresponding to the motor current and the proportional valve current is used as a basis for determining the rotational speed of the motor. 14 200825346 The ratio of the abnormal operating threshold, the control threshold and the over-pressure setting in the reference value corresponding to the machine are used as the basis for the motor speed. The advantage provided by the invention is that when the forced venting water heater = tuyere _ 纽 纽, or outside wind _ large, will stop '", 钇 gas, and block the supply of gas to ensure the use Safety of the person. Ability. ^The other advantage provided by the invention is that when the exhaust vent of the forced venting water heater is not seriously blocked, or the external wind pressure is still acceptable, the forced reading speed is used to compensate for the forced exhaust. The water heater emits the emission of combustion exhaust gas, and the provided is that, in the case of ensuring the normal operation of the forced exhaust hot water, the gas and the air introduced by the ignition control unit have appropriate wires, _ to the light dragon secret To ensure a good combustion condition, that is, high efficiency, low combustion exhaust gas value, etc. The closed type only provides a reference and said _, and _ to limit the invention. _ The above is only the preferred embodiment of the present invention.
