Abstract
The utility model discloses an electric heating water heater which is characterized in that an inner core is provided with a hollow cavity, and an earth pole is fixedly installed in the hollow cavity of the inner core; a phase pole and a zero pole are separately fixedly installed on the lower end of the inner core in an outer shell by forming container shapes, and the phase pole and the zero pole are homogeneously provided with water outlet holes; an insulator is arranged outside the zero pole or the phase pole which are closed to the outer shell. The utility model has the advantages of small size, convenient operation, high safety, low cost and high thermal efficiency, and the utility model can be used for shower, hair washing, washing and face and hand washing.
Description
The utility model relates to the technical field of water heater, specifically a kind of electrothermal water heater.
Existing electric heater mainly is categorized as two kinds of positive displacement and fast heating types, the problem that positive displacement exists: the one, volume is big, to water container be set specially, the 2nd, can not use at random, must pass through warm-up phase, treat that the uniform temperature side that is raised to waterborne in the container uses, the 3rd, water consumption be difficult to be estimated really difficult, and surplus hot water's heat energy volatilizees naturally and causes waste in the container when toing many or too much for use, when not enough, the coolant-temperature gage that newly covers is not enough, and influence is normal again uses; And the electrode of fast heating type mostly adopts stainless steel to do curl, being under the medium energising working condition with water, not only can produce surface corrosion, influence the water quality of made hot water, be to deposit sheet in the water, the steel body material of stratiform, and also all undesirable aspect the thermal efficiency and security.
The purpose of this utility model is to provide a kind of electrothermal water heater, it can solve heated quality problem, and volume is little, and can improve the thermal efficiency and security.
The technical solution of the utility model is achieved in that a kind of electrothermal water heater, it mainly comprises shell, be contained in the cover cap on the shell, be positioned at the shower nozzle of shell lower end, install in the enclosure inner core and electrode, and lead to the electrode contact of case surface, it is characterized in that: be provided with cavity in the inner core, the earth polar is packed in the cavity of inner core, the phase utmost point, zero utmost point are the container-like inner core lower end that installs respectively in the enclosure, the phase utmost point, zero utmost point are provided with apopore, are provided with insulator in the zero utmost point or phase utmost point appearance near shell.
The utility model is owing to adopt carbon to make container-like at two electrodes; water container must be set again makes machine volume little; and two electrodes directly are dipped in the water; it promptly is medium with water; directly electric energy is become heat energy; when water flows through and can heat rapidly from the space between two electrodes; and can make water quality not contaminated; appearance at electrode adds insulator; increased security, cooperated the utility model to be provided with automatic prompting power phase in addition, earth leakage circuit-breaker and close the control circuit of cutting off the electricity supply automatically in the water source; make safety more reliable, the utility model is tested by the test center of Shanghai City technical supervision department.
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 connects schematic diagram of the present utility model for installing
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises shell 4, be contained in cover cap 5 on the shell, be fixed with inner core 6 and three electrodes in shower nozzle 10, shell are equipped with in the lower end of shell, on cover cap except have with joint that water pipe links to each other draw the joint of each electrode in addition, it is different from prior art: be provided with cavity 9 in inner core 6, earth polar 3 in the electrode is packed in the cavity 9 of inner core, the phase utmost point 1, zero utmost point 2 all are container-like inner core 6 lower ends that are fixed respectively in the enclosure, are the container-like phase utmost point, zero and extremely generally can be bowl-shape, cylindric or tubbiness.Present embodiment is made bowl-shape, for the water quality after guaranteeing to heat, the phase utmost point, zero utmost point are made by conductive carbon, insulation mutually between three electrodes, the phase utmost point is different with the solid geometry size of zero utmost point, and promptly extremely comparable mutually zero greatly, also can be more minimum than zero, consider the characteristics of fast heating type, the phase utmost point is wanted suitably with the spacing of zero utmost point bowl wall and bottom; Present embodiment zero utmost point size is greater than phase utmost point size, being about to the phase utmost point places in the space that zero utmost point and inner core surrounded, thereby play the effect of the shielding phase utmost point, strengthen security, be provided with apopore 8 at the phase utmost point, zero on extremely, present embodiment is provided with apopore 8 in the bottom of the phase utmost point and the upper end of close zero utmost point, be outside equipped with insulator 7 at the zero utmost point or the phase utmost point near shell, present embodiment is close to one deck insulator 7 in the appearance of zero utmost point, to guarantee the not super safety standard of electric leakage, in the enclosure and be provided with the cavity of confession flowing water between the insulator of zero utmost point.Water pipe head with cover cap of the present utility model place; electrode leader connector is connected with power supply e with water source w and by safety electricity box b respectively; on safety electricity box b, install control circuit additional and have automatic prompting power phase translation function; electrical shock protection and close the function of cutting off the electricity supply automatically in the water source; need only fetch boiling water during use gate valve and power switch; the cavity of cold water in the pipe joint place of cover cap flows through inner core; to bowl-shape phase extremely in; heat as medium; flowing to zero utmost point from the apopore of the phase utmost point again heats; this moment, water temperature can reach 25-40 ℃; the adjusting of water temperature need be undertaken by Water gate valve, and the water after being heated is again from spraying near the shower nozzle from the shell lower end behind the cavity of apopore in shell of zero utmost point upper end.With electrical structure that the utility model matches on also be furnished with electrical power limit value device, using under the superpower situation, this dynamo-electric device is tripping operation in advance partly, unlikelyly influences the normal electricity consumption of user, so have bigger practicality.
