Description
Technical field
The utility model is related to a kind of PTC electric heater, and in particular to a kind of electricity on mobile air conditioner, dehumidifier adds
Hot device.
Background technology
In recent years, PTC electric heater is increasingly widely used in the household electrical appliance such as air-conditioning, warm-air drier, dryer.At present,
The thermel protection device of idle call PTC electric heater is generally housed within the installation pedestal of electric heater, but this kind of structure is for shifting
Dynamic air-conditioning and dehumidifier are not but very practical, main reason is that mobile air conditioner and dehumidifier are console mode, air inlet and air-out
Mouth is blocked and is considered its abnormal conditions for being easiest to occur, and the situation can produce serious shadow to electrically heated normal work
Ring, it is therefore desirable to design a kind of more sensitive electric heater of thermal protector function.
Content of the invention
The purpose of this utility model is for above-mentioned present situation, it is desirable to provide one kind can overcome drawbacks described above, low cost, product
Product stable performance, safety, the sensitive PTC electric heater of thermal protection performance.
The implementation of the utility model purpose is that a kind of PTC electric heater, heating core two ends are fixed on left and right base
On seat, metallic support is fixed on left and right pedestal side, and left and right pedestal opposite side is fixed on heating core；Thermal protector is fixed
On metallic support, outside thermal protector, there is sheath；Modeling seat is mounted on metallic support by screw, and thermal cut-off is mounted on modeling seat,
Zero line and live wire are drawn from the two ends of heating core respectively, and thermal cut-off and thermal protector seal in main circuit by electric wire.
Thermal protector of the present utility model, fuse are sequentially distributed on metallic support, and seal in circuit by wire, just
After damage, maintenance is changed；Zero line and live wire are drawn from the two ends of heating core respectively.With existing PTC electric heater structure phase
Than the utility model defencive function is more excellent, is especially used on mobile air conditioner and dehumidifier, when air outlet and air intake occurs in electrical equipment
During the abnormal conditions that mouth is blocked, thermal protector and thermal cut-off temperature-sensitive are sensitiveer, and defencive function is more excellent, and product is safer；And
Low cost, properties of product are stable.
Description of the drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the left and right base construction schematic diagram of the utility model,
Fig. 3 is the utility model modeling holder structure schematic diagram used.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is further detailed.
With reference to Fig. 1,1 two ends of heating core are fixed on left and right pedestal 2, and metallic support 3 is screwed in left and right
Pedestal side, metallic support are not connected with heating core itself, strengthen the insulating properties of heating core.
Thermal protector 4 is screwed on metallic support 3, has sheath 5, sheath to play insulation, prevent outside thermal protector 4
Water is acted on.Thermal cut-off 7 is mounted on modeling seat 6.Zero line and live wire are respectively from the two ends extraction of heating core, thermal cut-off and Re Bao
Shield device seals in main circuit by electric wire.
The circular hole that an area is slightly less than thermal protector temperature-sensitive face is provided with metallic support 3, and thermal protector 4 is solid by screw
Be scheduled on metallic support 3, thermal protector temperature-sensitive face just to circular hole, temperature-sensitive face can preferably temperature-sensitive heating core temperature, improve heat
Protector performance.
With reference to Fig. 2,2 side of left and right pedestal is inlaid with copper nut 21, simultaneously carries boss 22.Copper nut 21 is used for this reality
With the new installation in whole machine, position when boss 22 is easy to the utility model to install on whole machine, improve operating efficiency.
With reference to Fig. 3, modeling seat 6 is mounted on metallic support 3 by screw, and thermal cut-off is mounted on modeling seat, realize fuse and
The insulation of metallic support.There are two circular draw-in grooves 61 on modeling seat 6, bottom is provided with slot 62.Two circular draw-in grooves 61, are used for
The installation positioning of the electric wire of connection thermal cut-off.Slot 62 is easy to fuse temperature-sensitive.
Thermal protector of the present utility model, fuse are sequentially distributed on metallic support, and seal in circuit by wire, just
After damage, maintenance is changed；Zero line and live wire are drawn from the two ends of heating core respectively.With existing PTC electric heater structure phase
Than the utility model defencive function is more excellent, is especially used on mobile air conditioner and dehumidifier, when air outlet and air intake occurs in electrical equipment
During the abnormal conditions that mouth is blocked, thermal protector and thermal cut-off temperature-sensitive are sensitiveer, and defencive function is more excellent, and product is safer；And
Low cost, properties of product are stable.
