Description

Fully-automatic warm-air humidifier

A kind of full-automatic warm braw humidifier is mainly used in family life, belongs to the human lives and needs class.

In winter, spring, autumn three seasons, air is all very dry, and at northern area, the air degree of drying is more obvious, the heating of burner stove, and air humidity descends relatively, and this health to the elderly, children and patient is all very unfavorable.For addressing this problem, in recent years, electric heater, humidifier etc. have appearred on the market, and increasing indoor temperature and humidity, but the function of these products all is single, i.e. only heating and can not humidification or humidification and can not heating only.As buying said two products simultaneously, price height not only, and also it is big to take up room.

It is one with warming and humidifying function collection that the purpose of this utility model just provides a kind of, convenient economic full-automatic warm braw humidifier.

The utility model mainly is made up of motor, final drive shaft, fan, heater, water proof screen, driven power transmission shaft, driving wheel, driven pulley, water fog generator, tank.Motor is located at an end of warm braw humidifier, and motor shaft and final drive shaft join, and is provided with driving wheel, fan on the final drive shaft successively, and fan deviates from motor drive direction and is provided with heater and 2 U type water proof screens, and the fan on the final drive shaft can be one also can be two.Water proof screen outer end is that shutter is the warm braw outlet.Driven pulley is located at the driving wheel below and links by roller and driving wheel, wherein feels at ease and adorns driven power transmission shaft, and driven power transmission shaft is provided with water fog generator, and water fog generator is positioned at 2 water proof screen centre positions, and its below is provided with tank.After opening motor, driving wheel and fan begin to rotate, this moment is by circuit and machinery control, heater and water fog generator can also can be worked respectively simultaneously, as working simultaneously, then water fog generator is brought water in the tank into the humidification district and is clashed into wall and forms water smoke, and the globule falls or falls by V-type water proof screen mesopore along wall, gets back to tank.This moment, heater was also worked, and its ambient air temperature is than higher, and the hot-air that fan then will have water smoke blows out warm braw humidifier outside, and indoor temperature and humidity are increased.If think single heating or single humidification, can heater be quit work or water fog generator be stopped operating by circuit control by machinery control, then can achieve the above object.

The utility model realizes that the heating humidification is an one, improves service efficiency, promptly takes up room less, and cost is reduced, and is easy to use, provides condition for family and office create a favorable environment.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

As shown in Figure 1, motor is located at warm braw humidifier right-hand member, and motor shaft and final drive shaft join, and is provided with driving wheel, fan A, fan B on the final drive shaft successively.Driven power transmission shaft is located at final drive shaft below, and its right-hand member is a driven pulley, and driven pulley joins by roller and driving wheel, and driven power transmission shaft centre is provided with water fog generator, and the water fog generator bottom is immersed in the tank in the water.Be provided with heater and water proof screen A at fan A left end, heater can be a far infra-red heater, also can be resistance heater or plated film heater.The final drive shaft left-hand end is fan B, and fan B left end is followed successively by water proof screen B, shutter, shutter be provided with adjusting rod with the control shutter upwards, in, air-supply downwards.Warm braw humidifier upper left side is control and display part (Fig. 2), and people rotate knob and can control the warm braw humidifier for automatically, manually or regularly heating or single heating, single humidification, heating and humidification as required.Show indoor temperature and humidity simultaneously.Full-automatic warm braw humidifier circuit control is as Fig. 4, Fig. 5, Fig. 6.Wherein Fig. 4 is the control loop part, when the automatic knob of K(hand) when forwarding the below to, control loop is controlled by temperature, can automatically heater be stopped or working, and when K forwarded the top to, control loop was not worked by temperature control always.Work as K ₂When (selector switch) forwards 1 position to single humidification, at this moment, machine operation, the heater loop disconnects.Work as K ₂When forwarding 2 position to, motor and heater are worked simultaneously and are the warming and humidifying working method.Temperature sensing circuit (Fig. 5) by transformer B with civil power through R ₁, R ₂Current limliting and DW ₁, DW ₂Slicing voltage stabilizing, W ₁Thermo-sensitive resistor R is supplied with in shunting ₃Work, the alternating current of usefulness at this moment.Through bridge rectifier, become direct current, through capacitor C ₁, C ₂Resistance R ₄Form the filtering of π type.Because the influence of ambient humidity when causing change in resistance, the electric current in the circuit also will change thereupon, after transistor amplifies, just can demonstrate the variation of relative humidity with ammeter as Rs.After temperature detection control circuit (Fig. 6) becomes 8V by thermistor 220V, thermistor Rt and resistance R ₂, R ₃, R ₄, W ₁, W ₂Form potential-divider network, in thermistor Rt path, seal in ammeter and just demonstrate variation of temperature, resistance R rice is the resistance of regulating the displays temperature instrument, 555 time base circuits are as follows in the bistable operation process, the step-down after transformation of 220V civil power, after bridge rectifier filtering, supply with circuitry then, as contactor K(Fig. 4) when forwarding the below to, this moment, A point current potential was lower than 1/3 V _CC, 555 time base circuits, 3 pin output high level, relay J ₁Adhesive contact J ₁-1 is logical, and institute's control circuit is switched on starts working, simultaneously LED ₁Bright, expression heats up, and when temperature reached setting value, B point current potential was 2/3 V _CC, A point current potential is greater than 1/3 V _CCSo, the circuit upset, 3 pin are low level, J ₁Discharge J ₁-1 disconnects, and stops heating; LED ₂Bright.Be lower than when setting value to temperature, A point current potential is 1/3 V _CC, circuit is reworked, and so work is gone down, and reaches the purpose of control temperature.The action of selector switch (3) as shown in Figure 3.Rotating cam can be controlled the left and right position of link rod A, and action control roller and driving wheel, the driven pulley of the left and right position of link rod A by link rod B, link rod C, alignment pin (35) and spring links or break away from.Tighten transferring power by belt between roller and driving wheel, the driven pulley.When link rod A fixed on left position, belt unclamped between roller and driving wheel, the driven pulley, and driving wheel can not drive driven pulley, and driven pulley no longer rotates.When link rod A fixed on right position, belt was tightened between roller and driving wheel, the driven pulley, and driving wheel rotates and will drive the driven pulley rotation, and water fog generator also rotates thereupon.
