Abstract
The utility model relates to a built-in two-insurance washing machine heating pipe, which has a structure that a resistance wire (11) is arranged in a stainless steel tube (10), two ends of the resistance wire (11) are connected with an inner lead (12), a fuse (13), an outer lead (17) and an electrode lug plate (1) in sequence, the electrode lug plate (1) and the stainless steel tube (10) are sealed by sealing compound (5), and two poles of the resistance wire (11) are fixed with the stainless steel tube (10) through a steel flange (6) and a coupling sleeve (16). The heating pipe is characterized in that insulation magnesia (9) is arranged among the resistance wire (11), the inner lead (12), the outer lead (17), the fuse (13) and the stainless steel tube (10). The structure of the heating pipe is adopted, the insulation magnesia separates the inner lead, the fuse, the outer lead, the resistance wire and the stainless steel pipe in sequence;under the condition of dry combustion (no water), an electric heating pipe is heated to cause the temperature of the electric heating pipe to rise rapidly, so as to cause the temperature to rapidly transmit to the fuse; when the temperature reaches the cut-off temperature of the fuse within 30-80s, the heating temperature is cut off, thereby the purpose of protecting a washing machine is achieved, and the safety and the reliability are realized.
Description
Technical field
The utility model relates to the heating tube of heating tube, especially built-in double safety washing machine of the automatic washing machine of the security that improves household electrical appliance and reliability.
Background technology
Along with the intelligentized development of washing machine, automatic washing machine need be equipped with safe and reliable electric heating tube, and has only several families can produce this washtub abroad, does not meanwhile also form unified standard and advanced manufacturing technology.Though existing washing machine electric heating tube possesses security, possesses the security of dual fail-safe, promptly develops and develop the still untapped at present maturation of built-in dual fail-safe silk washing machine electric heating tube.
Electric heating tube is the key position in the double safety washing machine, as heating cold water, be characterized in that surface loading is bigger, volume is little, can make the aqueous medium Fast Heating, though existing fertile washing machine electric heating tube can play the effect that adds hot water, electrothermal tube continues heating under the situation of room temperature dry combustion method, can cause the washing machine burning, safety problem occur.Built-in simple insurance silk and built-in simple insurance silk+cooling-water temperature sensor can play the effect that adds hot water; electrothermal tube can cut off the current protection washing machine and not burn under the situation of room temperature dry combustion method; but can not guarantee fully at 30 seconds～80 seconds internal cutting off electric currents, can cause the washing machine burning.
Summary of the invention
At above defective, the purpose of this utility model is to provide a kind of built-in double safety washing machine heating pipe, is at the two ends of electrothermal tube difference installation insurance silk, make under dry-fire condition, can control the washing machine burning fully at 30 seconds～80 seconds internal cutting off electric currents, realize security.
The technical solution of the utility model realizes in the following manner: built-in double safety washing machine heating pipe, be to be provided with resistance wire in the described stainless steel tube, its two ends are connected with inner lead, fuse, outer lead, electrode tabs, described electrode tabs and stainless steel tube in turn and seal with sealing compound, fix by steel flange and adapter sleeve between resistance wire the two poles of the earth and the stainless steel tube, it is characterized in that: be provided with insulating oxide magnesium between described resistance wire, lead, outer lead, fuse and the stainless steel tube.
Above-mentioned adapter sleeve and stainless steel tube insulator seal.
Use insulator seal between above-mentioned inner lead and the stainless steel tube.
Adopt the utility model structure; used insulating oxide magnesium separates inner lead, fuse, outer lead and resistance wire and stainless steel tube successively; under the situation that dry combustion method (anhydrous) occur; the electrothermal tube heating can cause the electrothermal tube temperature sharply to rise, and makes temperature pass to fuse fast; when in 30 seconds～80 seconds, reaching the cut-out temperature of fuse to temperature; cut off heating power supply, thereby reach the purpose of protection washing machine, realize security reliability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
In the drawings, 1 is that electrode tabs, 2 is that insulator, 3 is that nut, 4 is that screw, 5 is that sealing compound, 6 is that steel flange, 7 is that rubber, 8 is that stainless steel platen, 9 is that insulating oxide magnesium, 10 is that stainless steel tube, 11 is that resistance wire, 12 is that inner lead, 13 is that fuse, 14 is that insulator, 15 is that insulator, 16 is that adapter sleeve, 17 is that outer lead, 18 is an insulator.
The specific embodiment
In Fig. 1, built-in double safety washing machine heating pipe is mainly by electrode tabs 1, insulator 2, nut 3, screw 4, sealing compound 5, steel flange 6, rubber 7, stainless steel platen 8, insulating oxide magnesium 9, stainless steel tube 10, resistance wire 11, inner lead 12, fuse 13, insulator 14, insulator 15, adapter sleeve 16, outer lead 17, insulator 18 is formed, wherein the two ends of resistance wire 11 are connected with inner lead 12 in turn, fuse 13, outer lead 16, electrode tabs 1, electrode tabs 1 and 5 sealings of stainless steel tube 10 usefulness sealing compounds, adapter sleeve 16 and 15 sealings of stainless steel tube 10 usefulness insulators, seal with insulator 14 between inner lead 12 and the stainless steel tube 10, fixing by steel flange 6 and adapter sleeve 16 between the two poles of the earth of resistance wire 11 and the stainless steel tube 10, insulating oxide magnesium 9 is successively inner lead 12, fuse 13, outer lead 16 and resistance wire 11 separate with stainless steel tube 10.
During work, electric current is by electrode tabs 1, outer lead 16, fuse 13, and inner lead 12 flows to resistance wire 11, and insulating oxide magnesium 9 and stainless steel tube 10 are passed in resistance wire 11 heatings, and heat is diffused in the ambient water again, makes water temperature reach needed requirement.Because the water temperature of washing machine is controlled in 80 ℃; stainless steel tube 10; the temperature of insulating oxide magnesium 9 and fuse 13 is in 80 ℃; so fuse 13 in normal operation; fuse 13 can not cut off; but when occurring under the situation of dry combustion method (anhydrous); electrothermal tube continues heating; can cause insulating oxide magnesium 9; stainless steel tube 10; the temperature of inner lead 12 sharply rises; make temperature pass to fuse 13 fast; in 30 seconds～80 seconds, reach the cut-out temperature of fuse 13 until temperature; cut off heating power supply; thereby reach the purpose of protection washing machine, the dual fail-safe silk is installed is made electrothermal tube under dry-fire condition, 100% guarantee at 30S～80S internal cutting off electric current; control the washing machine burning fully, realize security.
