Abstract

The utility model relates to a multipurpose hot wind machine. The utility model is mainly composed of a box body, a heating component, a fan, a wind inlet and a wind outlet. The heating component is composed of a honeycomb type thermistor ceramic chip, electrodes and a frame. The honeycomb type thermistor ceramic chip is pressed by the electrodes and the frame and is fixed by screws, and the fan and the heating component are arranged in the box body. As a consequence, the utility model has the advantages of simple structure, electricity saving, high heat exchange rate, long service life, etc.

Description

Multipurpose hot wind machine

The utility model relates to a kind of air-heater, particularly a kind of air-heaters of using more, and it is applicable to warming, air-supply in summer, and the usefulness of hot-air seasoning is made in the fields such as tealeaves, food, medicine and chemical industry that are applicable to.

Air-heater of the prior art, its heat generating member generally all are made up of resistance wire or plate ceramic heating spare, and resistance wire is big, fragile as its power consumption of heat generating member, the adstante febre resistance wire is rubescent, easily cause the danger of catching fire, the life-span is short, and its thermal efficiency only is 45%-50%; And plate ceramic heating spare carries out heat exchange by aluminium radiator fin, is that conducting resinl is bonding owing to what use between ceramics and the aluminium radiator fin, thus if then can't use after damaging, during ceramics temperature exceeds restriction simultaneously, its hot translation function decline, efficient is low.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and provide that a kind of reasonable in design is simple, power consumptive province, rate of heat exchange are high uses air-heater more.

The purpose that the utility model proposed can be achieved through the following technical solutions: design has blower fan and heat generating member, this heat generating member is made up of honeycomb fashion thermistor ceramics, electrode and framework, honeycomb fashion thermistor ceramics compresses with electrode and framework, and fix by screw, blower fan and heat generating member are installed in the casing.

Description of drawings is as follows:

Fig. 1 is the front view of the utility model heat generating member.

Fig. 2 is the right view of the utility model heat generating member.

Fig. 3 is a structural representation of the present utility model.

Fig. 4 is a front elevation of the present utility model.

Fig. 5 is circuit theory diagrams of the present utility model.

Fig. 6 is an another kind of structural representation of the present utility model.

Following the utility model will be described in further detail in conjunction with the accompanying drawings and by embodiment.

Referring to Fig. 1, Fig. 2, this heat generating member I is made up of honeycomb fashion thermistor ceramics 1, electrode 2 and framework 3, and honeycomb fashion thermistor ceramics 1 two sides compresses, is pressed on the electrode 2 with framework 3 with electrode 2, and fixing with screw 4 then, 5 is electrode tip.Wherein honeycomb fashion thermistor ceramics 1 can with three, also can be with 18,20,22 or 24 or the like, same, also can be by several heat generating member I recombinant members.

Embodiment one:

Referring to Fig. 3, Fig. 4, Fig. 5, the utility model mainly is made up of casing 6, blower fan 8, heat generating member I and air inlet 7, air outlet 9, the heat generating member I then is made up of honeycomb fashion thermistor ceramics 1, electrode 2 and framework 3, heat generating member I and blower fan 8 usefulness screws 4 are fixing, blower fan 8 can be fixing by screw 10 with casing 6, air inlet 7 is positioned at the rear portion of casing 6, and air outlet 9 then is positioned at the front end of heat generating member I.

During use, plug 11 is inserted power supply, open heat generating member switch 14, heat generating member indicator lamp 13 is bright, open fan switch 12 again, blower fan indicator lamp 11 is bright, and the heat generating member I begins heating, blower fan 8 brings into operation, the cold wind that air inlet 7 guiding is come in is by the fan blade guiding and the blast of blower fan 8, makes cold wind blow to the hole of honeycomb fashion thermistor ceramics 1, utilizes the feature of its porous and rapid heat dissipation, the heat generating member I is directly dispelled the heat in the hole that is covered with, form hot blast and outwards discharge, so constantly circulation, heating room air from air outlet 9, make it to warm, reach the purpose of heating.

In addition, a temperature controller also can be set and control the warm braw temperature.

Use in summer, can not open heat generating member switch 14, only open fan switch 12, the heat generating member I is not just generated heat like this, after blower fan indicator lamp 11 is bright, hot-air just enters from air inlet 7, under the effect of blower fan 8, blow to athermic honeycomb fashion thermistor ceramics 1, and in the hole that is covered with, dispel the heat, wind is cooled off and evenly, discharge gentle breeze from air outlet 9 at last, reach nice and cool purpose.

Embodiment two:

Referring to Fig. 6, present embodiment mainly is applicable to high-power machine, can be used as the usefulness of hot-air seasoning stove.It 7,9 is formed by casing 6, heat generating member I, overhead gage 16, blower fan 8, lower baffle plate 17 and into and out of the air port, one end of lower baffle plate 17 and casing 6 are fixed by screw, the other end and blower fan 8 are fixed by screw, one end of overhead gage 16 and casing 6 usefulness screws are fixed, the other end is then fixed with screw with the heat generating member I, the heat generating member I is positioned at the top of blower fan 8, and air inlet 7 is located at casing 8 positive lower ends, and air outlet 9 is located at the front end of heat generating member I.Like this, during work, cold wind can enter to blower fan 8 from air inlet 7, by blower fan 8 wind is delivered to the heat generating member I, by the heat generating member I warm braw is discharged from air outlet 9 again.

The utility model compared with prior art has the following advantages: 1, reasonable in design, simple, easily assembling; 2, adopt honeycomb type ceramic sheet combination in the heat generating member, had porous, rapid heat dissipation, feature that resistance is little, the rate of heat exchange height, and economize on electricity 30%; 3, heat generating member is not rubescent, and the flames of anger is safe and reliable, and the life-span is long.
