Abstract
The invention relates to a power-off restoration type quick heater comprising a U-shaped electrical heat tube and a thermal protector with PTC connected in series with the U-shaped electrical heat tube, wherein two ends of the U-shaped electrical heat tube are fixed on a plastic seat; the thermal protector with PTC is arranged in the plastic seat; a power wire for supplying power is introduced into the plastic seat and respectively connected with the U-shaped electrical heat tube and a series circuit of the thermal protector with PTC; an upper lug plate of the thermal protector with PTC is connected with a movable contact piece and a heat conducting plate by riveting and fixed on a support; a static contact piece is connected with a lower lug plate by riveting, and the lower lug plate and a pressing sheet are connected with the support by riveting; a bimetallic strip with a hole at the center is arranged on a column of the support; and a PTC heat emitting piece is arranged between the heat conducting piece and the pressing sheet. After being electrified, when water reaches boiling point, the movable contact piece and the static contact piece are automatically separated from each other, while the PTC heat emitting piece continuously emits heat; and the quick heater can restore only by pulling up a power plug after the PTC heat emitting piece is cooled, thus achieving the purposes of safety and energy conservation.
Description
Technical field
The invention belongs to household appliance technical field, relate in particular to a kind of power-off restoration type quick heater.
Background technology
Present on the market immersion heater, the automatically reseting and two kinds of hand-resets of outage type automatically.The type that automatically resets immersion heater can be unattended, and when after water is boiled, cooling off, thermal protector can automatically reset again, and if water will so repeatedly repeatedly, will be caused the thermos dry combustion method at last by heating once more, both dangerously also waste energy.And the manual replacement type immersion heater, complex structure uses also inconvenient.
Summary of the invention
The present invention provides a kind of cost low, easy to use, safe energy-conservation power-off restoration type quick heater in order to solve the problems of the technologies described above.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: the present invention includes the U type electrothermal tube; Also comprise the band PTC thermal protector of connecting with the U type electrothermal tube; The two ends of described U type electrothermal tube are fixed on the plastic seat; Described band PTC thermal protector is located in the plastic seat, and the power supply line is introduced in the plastic seat and with the series circuit of U type electrothermal tube with band PTC thermal protector and linked to each other.
As preferably, it is that 90 ± 3 ℃, reset temperature are 50 ± 10 ℃ thermal protector that described band PTC thermal protector adopts break-off signal; When described band PTC thermal protector was in on-state, its resistance was less than 0.1 Ω.
As preferably; Described band PTC thermal protector comprises lug plate, movable contact spring, conducting strip, static contact, following lug plate; Last lug plate and movable contact spring, conducting strip link to each other and are fixed on the bearing through riveting, and static contact links to each other through riveted joint with following lug plate, and following lug plate links to each other with bearing through rivet with compressing tablet; Center bimetal leaf with holes is arranged on the cylinder of bearing, and PTC heating sheet is arranged between described conducting strip and the compressing tablet.
The invention has the beneficial effects as follows: during work, because of band PTC thermal protector is in conducting state, two ends do not have operating voltage, and PTC heating sheet does not generate heat, and U type electrothermal tube two ends have rated voltage, U type electrothermal tube heating power.When water burns boiling point, behind the thermal protector temperature-sensitive, the contact automatic disconnection.At this moment since the PTC resistance much larger than the electrothermal tube resistance, PTC two ends have rated operational voltage, PTC heating makes thermal protector remain on normally open, no longer heating of electrothermal tube outage has reached after immersion heater water is boiled the no longer purpose of heating.Have only when pulling out attaching plug, band PTC thermal protector just can reset, and recovers the normal heating function, has reached safety, purpose of energy saving.
Description of drawings
Fig. 1 is a kind of circuit theory diagrams of the present invention.
Fig. 2 is a kind of structural representation of the present invention.
Fig. 3 is a kind of structural representation of band PTC thermal protector among the present invention.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically technical scheme of the present invention.
Embodiment 1: a kind of power-off restoration type quick heater of present embodiment; Like Fig. 1, shown in Figure 2; Comprise U type electrothermal tube 1, band PTC thermal protector 2, U type electrothermal tube 1 is in series with band PTC thermal protector 2, and the two ends of U type electrothermal tube 1 are fixed on the plastic seat 3; Band PTC thermal protector 2 is positioned at plastic seat 3, and power supply line 4 is introduced in the plastic seat 3 and with the series circuit of U type electrothermal tube 1 with band PTC thermal protector 2 and linked to each other.
As shown in Figure 3; Band PTC thermal protector 2 comprises lug plate 5, movable contact spring 6, conducting strip 7, static contact 8, following lug plate 9; Last lug plate 5 and movable contact spring 6, conducting strip 7 link to each other and are fixed on the bearing 10 through riveting, and static contact 8 links to each other through riveted joint with following lug plate 9, and following lug plate 9 links to each other with bearing 10 through rivet with compressing tablet 11; Center bimetal leaf 12 with holes is arranged on the cylinder of bearing 10, and PTC heating sheet 13 is arranged between conducting strip 7 and the compressing tablet 11.
It is that 90 ± 3 ℃, reset temperature are 50 ± 10 ℃ thermal protector that band PTC thermal protector 2 adopts break-off signals.The resistance of PTC heating sheet is 10K Ω, and the resistance of U type electrothermal tube is 50 Ω.When band PTC thermal protector 2 was in on-state, its resistance was less than 0.1 Ω.
The course of work: after the energising, immersion heater is started working, the heating of U type electrothermal tube; When external temperature rises to specified break-off signal, receive the drive of bimetal leaf, movable contact spring separates with static contact; Electrothermal tube quits work; Electric current conducts to down lug plate and forms path through last lug plate, conducting strip, PTC heating sheet, compressing tablet, rated operational voltage (the PTC resistance is much larger than the electrothermal tube resistance) on the band of PTC heating sheet two ends, the heating of PTC heating sheet; Make the thermal protector body temperature remain on it more than reset temperature, thermal protector remains on normally open.Have only the outer power supply of executing that cuts off the thermal protector two ends, PTC heating sheet stops heating, reduces to reset temperature when following when the thermal protector body temperature, and thermal protector is resetted, and immersion heater is task again, has reached the effect of power-off restoration.
Easy to use, energy-conservation and purpose of safety that the present invention has reached, and manufacturing cost is lower, has strong practicality.
