After the water is exhausted, the power supply is automatically cut off, and the utility model stops heating.

Description

Wall type automatic electrical water heater

The utility model relates to the improvement invention of electric kettle, the particularly improvement of domestic electric heating kettle.

In the prior art, domestic electric heating kettle, the heating of employing electrothermal tube, need manually add plugs in behind the water just begins heating, water is opened the back if nobody pulls out plug, then can heat always, water level is reduced under the heating tube up to water evaporation back, and heating tube makes whole heating system burn short circuit because of self-temperature raises significantly, causes unpredictable consequence, and because of manually adding water, after opening, water also need people's frock water to go into the thermos bottle insulation, the tired lock of operation, the ground of also may getting wet, strengthen labour intensity, also need establish the place of placing thermos bottle.

In view of the deficiencies in the prior art, the utility model aims to provide a kind of adding and is heated to boiling point and insulation behind the water automatically, use up the self-controlled electric heated water tank of cutting off the electricity supply automatically and stopping to heat behind the hot water, another purpose of the present utility model mainly is to adopt the mode that embeds wall, saved the placement space of laying thermos bottle, both safe and reliable, health, easy again.

The utility model is realized in the following ways: the utility model comprises shell (1), heat-insulation layer (2), inner bag (3), heater (4), water inlet (5), delivery port (6), in internal bladder cavity (7), be provided with the transmission device (10) that connects buoyancy aid (8) and following level control switch for water (9), the extreme lower position of buoyancy aid (8) is located at the top of heater (4), is provided with temperature detect switch (TDS) (11) at inner bag (3) outer wall.

The utility model compared with prior art, have that automatic adjusting heats up or insulation and have that water heats automatically, the anhydrous function of cutting off the electricity supply automatically and stopping to heat, and the embedding wall reaches and makes full use of the space, increase the use place under the present acute housing shortage situation, and manufacturing is simple, cost is low, installs easily.

Accompanying drawing has been represented structure of the present utility model and principle thereof, and existing I, II are further set forth structural principle of the present utility model and use in conjunction with the embodiments.The utility model embodiment I: comprise housing (1), heat-insulation layer (2), inner bag (3), heater (4), water inlet (5), delivery port (6), in internal bladder cavity (7), be provided with the toggle (10) that connects buoyancy aid (8) and following level control switch for water (9), the extreme lower position of buoyancy aid (8) is higher than the position of heater (4), is provided with temperature detect switch (TDS) (11) at inner bag (3) outer wall.Inner bag (3) communicates with transparent water level observation tube (13); in order to observe water level; following level control switch for water (9) is by on connecting; lower contact (14); (15) elastic contact blade (16) control; on; lower contact (14); (15) be fixed on after isolated by insulator (24) respectively on switch frame (25) and the inner bag (3); buoyancy aid (8) drives toggle (10) because of the back water level of intaking floats and rotates; push rod (26) drive activity top (27) upwards promotes elastic contact blade (16) and connects upper contact (14); then circuit is connected and is started working; heat temperature raising is to boiling point; temperature detect switch (TDS) (11) is cut off the electricity supply automatically and is stopped heating; begin insulation by heat-insulation layer; when naturally cooling to 70 ℃ of left and right sides; temperature detect switch (TDS) is conducting once more; heater begins heating once more until boiling point; again insulation move in circles until hot water use up into to (certainly therebetween also can in the middle of arbitrarily water inlet; heat temperature raising is incubated to boiling point again); when being reduced to the extreme lower position of buoyancy aid (8) under the hot water water level; then descend the elastic contact blade (16) of level control switch for water (9) to reset; descend and connect lower contact (15); heater (4) stops heating work to protect whole heating system so at once; guarantee safety, in use these signals are by the intensification that is located at the mounting shell surface (19); insulation (20); water (21) is arranged; anhydrous (22) four indicator lamps are represented.

The utility model example II: in internal bladder cavity (7), be provided with the lever construction that connects buoyancy aid (8) and following level control switch for water (9), and by the isolated level control switch for water (9) down of sealing ring (36).Water level rises then, and buoyancy aid (8) floats, utilize lever principle to move down by the spring contact (34) that pin (35) is connected the following level control switch for water (9) of lever (10), press knob (33), circuit is connected, begin heating and rise heat and insulation, until almost using up hot water, be lower than the extreme lower position of buoyancy aid (8) when water level, then spring contact (34) disengagement knob (33) resets, be opening, circuit disconnects and stops heating, to save heater (4) and whole heating system, its intensification equally from damage, insulation, water is arranged, anhydrous by four indicator lamp indications that are located at surface of shell.

Simultaneously, the utility model is provided with spilling water blast pipe (12) in internal bladder cavity (7), the height of its upper end is used for controlling the highest order of water level in the courage, the lower end level is led to shell, if careless water level surpasses the height of spilling water blast pipe (12), then excessive water is discharged internal bladder cavity thus automatically, if temperature surpasses boiling point in the courage, then water evaporation back steam is discharged to keep pressure in the courage by spilling water blast pipe (12); The utility model connects water intaking valve (17) after adopting water inlet pipe to enter inner bag, and the other end of water intaking valve (17) picks out water pipe (18), avoids not going out because of hydraulic pressure is not enough the defective of water; The utility model can also be drawn a plurality of delivery ports (23), but but use and the regulated at will hot water temperature with regard to many places after connecting cold and hot dual-purpose water nozzle; The utility model adopts the mode that embeds wall, overcome and laid a large amount of thermos bottle and take and use place and the clumsy deficiency of tired lock, only need whole self-controlling electrothermal water tank is placed in the wall of relative set, tighten hold-down screw (29), plug (30) plugs in, opening power gauge tap (31) after the valve switch of outwarding winding (32) water inlet, is an edible when the intensification indicator lamp skips to the insulation indicator lamp.Using the utility model not only easy and healthy but also safe and reliable, reduced the labour intensity in the housework significantly, is the desirable water heater that family is equipped with.

The utility model can also be provided with big suppending hole at least two following little on the back shroud, so that use decorating fully to be suspended on the wall in the good room.
