Description
Affiliated technical field
The utility model relates to a kind of EWH, is a kind of instant electric water heater specifically.
Background technology
At present, known electric heater, adopt preheating insulation formula electric heater mostly, the water heater of this type, need first preheating before using, the deficiency that need wait for when having bathing, this type of electric heater also can be incubated power connection at ordinary times always, can use at any time with assurance, but have the deficiency that increases power consumption.
Also there are some instant electric water heaters to occur now on the market.In the processing for electricity danger, the instant electric water heater adopts the electricity separation formula to solve safety problem on calandria mostly.Because can not tackle the problem at its root, this class electric heater for this reason all adapted leakage switch, electrical shock protection wait to come auxiliary anti-, but electricity separation formula calandria, leakage switch, electrical shock protection all have certain service life, if wherein parts damage suddenly just in use and produce electric leakage, its consequence is with hardly imaginable, and this type of electric heater is through the use of a period of time, and calandria very easily stops up because of fouling, is difficult to handle; This type of electric heater complex structure of while, price and maintenance cost are all very high.
Summary of the invention
Goal of the invention of the present utility model is to provide the fast thermoelectric power water heater that can reach nonvolatil effect in a kind of cleaning simple in structure, easy, thermal efficiency height, the processing for electricity danger.
The technical solution of the utility model is: a kind of fast thermoelectric power water heater comprises calandria, power supply and control circuit thereof.Water heater is assembled relatively by two insulation boards, and insulation board is provided with Baltimore groove, and its Baltimore groove formed curved lengthening inlet channel, heating clamber and curved lengthening water outlet when two insulation boards assembled relatively; Curved lengthening inlet channel is connected with the heating clamber lower end, and curved lengthening water outlet is connected with the heating clamber upper end; Curved lengthening inlet channel is connected with the water inlet interface, and curved lengthening water outlet is connected with the water outlet interface; Calandria is arranged in the heating clamber, and calandria is connected with power supply and control circuit thereof.
Described calandria is a tungsten filament.
Be provided with on described curved lengthening inlet channel or the curved lengthening water outlet one can current by the time connect heating control circuit to current heat, the disconnection heating control circuit stops to heat when current disconnect water flow switch.The switch output stage of water flow switch links to each other by the control circuit of relay with the water heater calandria.
Described curved lengthening inlet channel and curved lengthening water outlet cross-sectional area are less than the heating clamber cross-sectional area.
Described curved lengthening inlet channel and curved lengthening water outlet equal in length.
The described insulation board that is provided with Baltimore groove is one, and another insulation board of relative assembling with it is a shape of plate plane.
The described insulation board that is provided with Baltimore groove also can be two, and its Baltimore groove of two insulation boards up and down of assembling is symmetrical relatively.
Described two insulation boards are equipped with the high-temperature insulation plane leather packing onesize with it therebetween when assembling relatively.
The utility model is bigger because of the heating clamber cross-sectional area, calandria directly is contacted with in the water, curved lengthening inlet channel and curved lengthening water outlet cross-sectional area that cause is communicated with it are less, the utility model has elongated the distance of curved lengthening inlet channel and curved lengthening water outlet again, and it is with equidistant, make its water form a powerful resistance at the interface at two ends, make the electricity of 200V voltage in the heating clamber have only several megaohms, thereby can reach the electric effect of reliable and permanent resistance to the electric current resistance of water inlet interface and water outlet interface.
Compared with prior art, the utlity model has advantages such as to reach the electric effect of nonvolatil resistance in simple in structure, easy cleaning, thermal efficiency height, the processing for electricity danger.
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
Description of drawings
Fig. 1 is embodiment 1 structural representation of the present utility model.
Fig. 2 is embodiment 2 structural representations of the present utility model.
