Abstract

The utility model relates to a PTC warming main machine, which comprises a volute, a wind wheel and a generor. The volute is arranged on a bracket fixedly, a sealed cavity is formed by volute and volute shell, the wind wheel and the generator is arranged in the cavity, the wind wheel is connected with the output stalk of the generator and is faced to the outlet; the wind wheel, the generator, volute cover and outlet are arranged on the same axial ray, the lower part of the volute is connected with PTC cover, the PTC heating element is equipped in the PTC cover, the heating surface of the heating element is communicated with the debouchement of the lower part of the volute shell and is faced to lower part of the wind wheel. Beneficial effect of the utility model is: the PTC warming main machine uses advanced PTC ceramics heating block to warm, has low heat inertia, need not wait, forces convection conduction, the model is warm whenever is opennned, improves the state that traditional lapm warming is slow, and is of high effect, does not illuminate, has no open fire and no radiation, resists shake strongly, is of long life; especially the effect of saving energy is very significant, PTC output power decreases while the environmental temperature rises, the model has the effect of saving energy.

Description

The PTC main frame of warming oneself

Technical field

The utility model relates to heating main frame field, mainly is a kind of PTC heating main frame.

Background technology

At present to be commonly called as product such as super bath be to adopt the infrared lamp heating to the bathroom warming lamp that uses, electrothermal calefactive rate is slower, if weather cold situation under, then need to wait for long period of time, and in case after the heating, be in high thermal inertia state for a long time, consumed power is big, owing to be in the high temperature operating state for a long time, security performance also is short of to some extent, and working machine service life neither be very long.

Mostly existing warm-air drier is to go out to be provided with heater element at the air outlet of blower fan, the heater element that adopts is commonly hardware, as copper wire, nickel filament etc., the thermal efficiency that this class heater element produces is low, security is not high, service life is short, and the feature that decays in time of its power in addition can not satisfy user's actual needs.

Summary of the invention

The utility model will solve above-mentioned existing shortcoming, and a kind of rational in infrastructure, efficient, energy-conservation, safe PTC heating main frame is provided.

The utility model solves the technical scheme that its technical problem adopts: this PTC heating main frame, mainly comprise spiral case, wind wheel and motor, spiral case is fixedly mounted on the support, and form the cavity of sealing with spiral case lid, wind wheel and motor are installed in cavity, and wind wheel is connected with motor output shaft and over against air outlet; Wind wheel, motor, spiral case lid and air outlet are arranged on the same axis, and the spiral case below is fixedly connected with the PTC lid, in the PTC lid PTC heater element are housed, and the opening of the heating face of PTC heater element bottom spiral case communicates and be right against the bottom of wind wheel.

The effect that the utility model is useful is: this PTC heating main frame adopts advanced PTC ceramic heating piece heating, have low thermal inertia, need not to wait for, the conduction of forced convertion formula, promptly open promptly warm, improved the slow situation of the warm heating of conventional lights, and thermal efficiency height, not luminous, the flames of anger, radiationless, superpower antidetonation, the life-span is long; Especially its energy-saving effect highly significant, PTC power output raise with environment temperature and reduce, and have high energy-conservation effect.

Reference numeral: spiral case 1, wind wheel 2, motor 3, PTC heater element 4, support 5, spiral case lid 6, wiring lower cover 7, PTC lid 8, electric capacity 9, binding post 10, ply-yarn drill 11, wiring loam cake 12, fixture block 13, draw-in groove 14, inserted sheet 15, slot 16, temperature controller 17, regulating tank 18, air outlet 19.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As depicted in figs. 1 and 2, this PTC heating main frame, mainly comprise spiral case 1, wind wheel 2, motor 3 and PTC heater element 4, spiral case 1 is fixedly mounted on the support 5, and form the cavity of sealing with spiral case lid 6, the outside of spiral case lid 6 is provided with wiring lower cover 7, and wiring lower cover 7 is fixedlyed connected with spiral case lid 6, spiral case 1.Support 5 is provided with regulating tank 18, and spiral case 1 can pass through bolt, is adjusted to corresponding height in regulating tank 18.

Wind wheel 2 and motor 3 are installed in cavity, and wind wheel 2 is connected with motor 3 output shafts and over against air outlet 19; Wind wheel 2, motor 3, spiral case lid 6 and air outlet 19 are arranged on the same axis, spiral case 1 below is fixedly connected with PTC lid 8, in the PTC lid 8 PTC heater element 4 is housed, PTC heater element 4 is provided with one group of inserted sheet 15, PTC lid 8 is provided with slot 16, inserted sheet 15 inserts slot 16s during installation, with fixing PTC heater element 4.The heating face of PTC heater element 4 communicates with the opening of spiral case 1 bottom and is right against the bottom of wind wheel 2, and when needing heating, heat enters in the cavity from the opening of heating face by spiral case 1 bottom, and the rotation by wind wheel 2 blows out the wind of high heat from air outlet 19.

Be connected with wiring loam cake 12 on the described support 5, be provided with electric capacity 9, binding post 10 and ply-yarn drill 11 in the wiring loam cake 12; Wiring loam cake 12 and support 5 are by fixing in the draw-in groove 14 on the 13 insertion supports 5 of the fixture block on the wiring loam cake 12.Cover 6 inboards at spiral case, be provided with temperature controller 17, make limiting temperature be controlled at the curie point annex, can limit temperature automatically, have high security near PTC heater element 4 places.

When environment temperature arrives set point, apply voltage, cut off voltage automatically, make heat release only change within the specific limits, remain on temperature constant state substantially; After temperature fell after rise, energising automatically continued the heat release of heating again.Whole host design is reasonable, outward appearance succinct, efficient, safety.The built-in PTC heating of ventilation fan, ventilation solves the needs of heating simultaneously, and the device that the two separates under the state that need not to warm oneself, can singly be opened the function of ventilation, and the design of hommization is more reasonable.
