Abstract
The utility model discloses a strong discharging water heater with a two-way control device. The utility model comprises an air flue and a motor of drive blower, which is characterized in that the motor is brushless DC motor supplied by mains supply through the fairing. The brushless DC motor control unit has the structure that both the feed back signal wire having a frequency being directly proportional to the rotate speed of the motor in the extension wires of brushless DC motor and the current signal wire of the winding extension wire are connected with the air inlet valve switch and simultaneously control the air inlet valve switch. The frequency signals and the current signals are connected with the door and both simultaneously satisfy preset value. The utility model converts the AC with 50Hz, 220V into DC(e.g. 24V, 12V); two signals are used for controlling valve and ensuring the safe discharging being on the safe side. The utility model can use natural gas, gas oil etc. as the fuel, and has the advantages of rapid discharge, high heat efficiency, energy saving and environmental protection.
Description
Technical field
The utility model relates to a kind of forced-ventilated water heater that has the two-way control device.
Background technology
Commercially available forced-ventilated water heater is to adopt alternating current generator to drive blower fan at present, and the water heater waste gas after burning is got rid of by flue, it is indoor that harmful waste gas is not flow to, the fan outlet of water heater is provided with wind pressure sensor, when the blower fan rotation, in the time of can discharging fume, the wind pressure sensor of fan outlet is with output signal, start blast switch, open burnt gas valve, this makes water heater as if working and taking fire combustion gas, the condition that must at first possess forced fume exhaust is to guarantee safety.Yet existing water heater but is difficult to reach above-mentioned requirements.
The utility model content.
The purpose of this utility model provides a kind of forced-ventilated water heater that has the two-way control device.
Above-mentioned purpose of the present utility model adopts following technical scheme to be achieved:
The utility model comprises the air channel and drives the motor of blower fan that it is characterized in that: described motor is a brshless DC motor.
Described brshless DC motor through fairing by mains-supplied.
The concrete structure of described brshless DC motor two-way control device is: in the lead-out wire of brshless DC motor, be proportional to the feedback speed signal line and the while of the current signal line in the winding lead-out wire control connection inlet port valve door switch of motor speed by frequency.
Described frequency signal and current signal are and door link.Must satisfy setting value simultaneously.
Because the utility model has adopted technique scheme, thereby utilize fairing with 50Hz, the alternating current of 220v is converted to direct current (24v for example, 12v), in addition, remove by-pass valve control with two signals, its reason is: frequency signal only shows whether motor works, but can not show whether blower fan works (throwing off) as blower fan and motor shaft, if blower fan is work not, if error starting valve, then the waste gas of burning still can't be discharged, this situation is very dangerous, and current signal shows that motor has driven blower fan work, and operating current is big when driving blower fan, and do not drive blower fan, when singly being motor oneself commentaries on classics, operating current is little, therefore only reaches the operating current (as 0.35A) of a certain setting, can the starter gate valve door switch.Singly have current signal also cannot because during motor rotation blockage, electric current is arranged, but motor does not change, and blower fan also is inoperable, determines that blower fan work is only in frequency signal and the satisfied simultaneously setting value of current signal, just can open valve, guarantee safe exhaust, perfectly safe.The utility model can use natural gas, oil liquefied gas equal energy source, exhaust is rapid, the thermal efficiency is high, energy-conserving and environment-protective, though increased by a cover rectifying installation, but replaced expensive blast switch, the dc source of the ignition switch of former AC motor system is provided and needn't be set up by the power supply of brshless DC motor, draw and overall cost uses the existing product of blast switch to reduce, by frequency and the dual control signal of electric current to control the air intake valve switch with the door mode, make water heater increase dual fail-safe undoubtedly, security performance improves greatly.The utility model can also improve installation situation, more is suitable for the air channel of lengthening, strengthens the exhausting dynamics, and electric power consumption can reduce by 50%.Because the brshless DC motor rotating speed is adjustable, in addition with speed governing and intake valve interlock, can when strengthening air inflow, improve rotating speed of motor, improved exhausting waste gas intensity, guarantee under the different situation of flame size, exhaust capacity all adapts with it automatically, exhaust blast and combustion intensity follow-up adjustment, not only safety but also save electric energy.

Fig. 2 is the utility model structure control principle schematic
The specific embodiment
As shown in Figure 2:
The utility model comprises air channel 1 and drives the motor of blower fan 2, it is characterized in that: described motor 3 is brshless DC motor.
Described brshless DC motor through fairing by mains-supplied.
The concrete structure of described brshless DC motor two-way control device is: in the lead-out wire of brshless DC motor, be proportional to the feedback speed signal line and the while of the current signal line in the winding lead-out wire control connection inlet port valve door switch K of motor speed by frequency.
Described frequency signal and current signal are and door link.Must satisfy setting value simultaneously.
Described brshless DC motor is fixed on the support 5 by base plate 4, and described support 5 is fixed on blower fan 2 housings, and base plate 4 is provided with control circuit board 6.
Obviously, described brshless DC motor can be selected various types of brshless DC motors.
As Fig. 1 and Fig. 2 contrast as can be known: the utility model can also omit the cooling fan 7 that alternating current generator institute must use.
