Description of the Invention: [Technical Field of the Invention] The present invention relates to a water heater. More specifically, it refers to a type of powerful water heater and a safety detecting method thereof. [Prior Art] It is known that a water heater that uses natural convection to exhaust exhaust gas often cannot discharge carbon monoxide generated in the event of incomplete combustion to the outside due to excessively slow air circulation, so that it is easy for indoor personnel to inhale excessive carbon monoxide due to obscurity. Causes harm to life. Based on this, some manufacturers have developed a type of powerful water heater, which uses a blower to force the air inside the water heater to circulate, so that the carbon monoxide generated by incomplete combustion is discharged to the outside, and can be heated by the heater. Efficiency, while providing more air, and increasing the supply of more heat. However, when the blower of the strong water surface aging or the exhaust pipe is blocked, the air circulation efficiency of the strong tapping hot water is lowered, and the probability of carbon monoxide generation is increased, and when the user inhales carbon monoxide, the human body will be caused. Tissues are deprived of oxygen and cause discomfort, and even more, there is a risk of death. The user is determined to be safe and secure because of the use of the strong plastic water heater, which will cause the user to be in a dangerous place without knowing it. SUMMARY OF THE INVENTION In view of this, the main object of the present invention is to provide a strong attack type water heater 201200822 and its safety inspection (four) method for the speed of the lion riding is to hang to achieve safety detection purposes. In order to achieve the above object, the safety detection method provided by the present invention comprises: setting a pre-judging reference in the calculation unit, the reference value of the rotation speed value is bounded by the value of the lowest critical speed to the maximum critical speed value. Then, after the blower of the fine water heater starts the running speed value of the running motor for a period of time, and compares the rotational speed value of the running motor, the value of the running motor falls outside the miscellaneous reference rhyme, and if the rotational speed value of the running motor falls into a fine (4), The drum _ gas is supplied to the heater of the water heater. The water heater for performing the above safety detection method comprises a heater, a gas proportional valve, a blower, a detecting device and a control device. wherein the gas proportional valve Provided on a gas supply path for controlling the supply of gas to the heater; the blower is provided with an operating motor for forcibly introducing air + § heating g; the rotational speed of the running motor of the thin-faced blower, The control device has the calculation unit, and the calculation unit is electrically connected to the detection device, and the calculation unit is under any set gas supply amount, The speed value reference range is set, and when the motor speed value measured by the detecting device falls outside the reference value of the speed value, the steering device controls the gas proportional valve to block the gas supply path to stop the supply. The gas is given to the heater. [Embodiment] In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the detailed description of the present invention. The first embodiment is not intended to be a structural configuration of the water heater 1 according to the preferred embodiment of the present invention, and the first figure is a flow chart of the safety detecting method of the present invention. The water heater 1 of the present embodiment includes a heating method. 10, a gas proportional valve 20, a blower 30, a detecting device 40, a control skirt 5, and a sounding device 60. wherein: the heater 1 is disposed below a water pipe 101, It is used to heat the water in the water pipe 101. The exhaust gas generated when the heater 10 is heated is discharged by a draft pipe 102 constituting one of the exhaust pipes. The gas proportional valve 20 is disposed in a gas. 103, and located on the gas supply path, has the effect of regulating the amount of gas supplied to the heater 10, and the gas proportional valve 20 can be a wide flow rate contro1 valve of the US Patent Publication No. 20090206291A1 filed by the applicant. The current is supplied to make the valve proportionally open, that is, when the current supply is larger, the valve opening degree is proportionally increased, and the gas flow rate provided is proportionally increased. Of course, other mechanisms can be utilized in design. The design, such as the rotary dislocation opening method, can control and calculate the supply of gas. The air blower 30 is disposed under the heater 1b, and has an internal running motor such as a DC brushless motor 32. When the DC brushless motor is actuated, the external port exhaust gas can be introduced into the air blower 30 from the air inlet 30a. Discharged to the heater 1 through the air outlet, thereby mixing with the gas to achieve the purpose of combustion support; 5 5 201200822 It is known that the rotational speed of the DC brushless motor 32 is proportional to the amount of air provided by the blower 3〇, that is, The greater the rotational speed of the brushless DC motor 32, the greater the amount of air provided by the blower 30. The smaller the DC brushless motor 32 is, the less the air volume of the blower 30 is. For example, the detection device 4 is an example of a Hall element disposed in the air blower 30 in this embodiment, but is not limited thereto, and is used to detect the DC brushless motor 32. Rotating speed. The control device 50 has a calculation unit 51 electrically connected to the detection device 4'. The calculation unit 51 sets the basis of the theoretical rotation speed value of the theoretical rotation speed value under any set gas supply amount. Therefore: as shown in the fourth figure, under the condition of generating combustion, the provided air supply and gas flow have the best air-fuel ratio of -疋, that is, the gas-valve valve 2 () calculates the gas stem Providing, the optimal air-fuel ratio can be used to calculate the amount of air that the blower 30 must provide and the theoretical speed value of the DC brushless stirrup; in addition, the blower of the storm-type water heater is aged, and the air volume of the intake air Insufficient will cause - the amount of carbon oxide is increased, or when the exhaust pipe is blocked, the internal air can not be added to the 'both will cause - the amount of carbon oxide is increased; · the needle is aging, the L-hanging starts to start the DC brushless motor % of the speed is lower than - the allowable value of the 'will cause' - the increase of the amount of carbon oxide, our wire hides the low critical speed ^ 'The other problem is the pipeline blockage problem, _ pressure is large, so increase the air compensation' Straight The rotational speed of the brushless motor 32 will increase abnormally. This abnormal speed increase value is defined as the highest critical speed value. When the speed of the DC brushless motor %201200822 is higher than this allowable value, it indicates that the exhaust pipe is blocked. The increase in the amount of carbon oxides will be a risk of 4%, and the minimum critical speed value and the maximum critical speed value are constructed into a reference range of the rotational speed value. It should be noted that the above theoretical rotational speed value, minimum critical rotational speed value and maximum critical rotational speed value are set according to different motors, and are preset before the water heater 1 is shipped. Please refer to the fifth figure, which refers to the gas supply of any setting. The curve eight meter shows that the DC brushless motor 32 is in an ideal state (ie, the power supply is normal, the internal components of the blower 3〇 are not aged, and the guide The speed curve of the case when the flow f 102 is not blocked. The DC brushless motor 32 has a smooth increase in speed during the speed increase from the time point a to the time point b, and becomes a fixed speed state after reaching the time point b. The theory of the theory of riding refers to the approximate value of the DC brushless motor 32 in the 敎 state. Moreover, the value of the speed of the gambling ship is an example of a theoretical speed of 0.7 times. The maximum critical speed value is 1 〇 4 times the value of the speed of rotation. However, it should be noted that the setting of these magnifications can be Adjust it according to the type of motor. In addition, the detecting device 4 is, after the time point, starts to cross-measure the rotational speed value of the DC brushless motor 32, and when the DC brushless motor is turned lightly in the miscellaneous reference n, At this time, the blower % works normally, in other words, the water heater! The interior maintains good air circulation efficiency. On the contrary, please refer to the curve B in the fifth figure. When the abnormal situation occurs, such as damage or aging of the internal parts of the blower 3, the energy loss will be too large when the DC is not up to 32, so that the operation cannot be effectively improved. The speed of the DC brushless motor 32 detected by the side spreader will be lower than the minimum critical speed 201200822, and the air circulation efficiency inside the water heater 1 may be poor, so that the heater 10 is easily burned. The gas is incomplete and produces carbon monoxide, which causes discomfort when the user uses the water heater 1, and even more risks of death. The curve C of the fifth figure indicates that the water conduit is blocked before the water heater is used, and the air pressure of the air blower 30 is increased due to poor air circulation efficiency after the DC brushless motor 32 is started. , causing the speed to continue to face. In addition, when the water heater 1 is in use, the sudden depression of the draft tube 1〇2 also causes the internal air pressure of the blower fan 30 to rise, so that the rotational speed of the DC brushless motor 32 will rise as shown by the curve D. Both of the above situations will cause the speed of the detecting device 40 to the DC brushless motor 32 to exceed the highest L-boundary speed value' and both will cause the carbon dioxide to be generated due to incomplete gas in the heater 1G. . Therefore, when the control device 5 〇 finds that the rotational speed of the straight flow brushless motor falls outside the reference range of the rotational speed value, then the gas ratio steel is controlled to block the gas supply path #:, Supply gas to the fresh (1), in order to curb the possibility of oxidation. At the same time, the warning message such as s-fan aging or "drainage tube blocking" is generated for the warning device of a display screen, so that the user can timely understand the abnormality of the water and the like. Repair and maintenance. In addition, the control farm 50 further has a late connection with the blower 3〇 controller 52'. The delay controller 52 is configured to control the blower 30 after the gas ratio side 20 blocks the 2011200822 gas supply path. The DC brushless motor 32 continues to operate for a period of time before it stops. The purpose is to discharge the carbon monoxide which may be generated inside the water heater i to reduce the probability of carbon monoxide poisoning by the user.
