Description
Technical field
The utility model relates to a kind of electric water heater, relates in particular to a kind of insulation indicating circuit of electric water heater.
Background technology
At present, existing Domestic electric water-heating utensil major part only has simple heating function, although some has heat insulation function, but can not realize random adjusting and be incubated required temperature, people in actual use, can be according to the different demands that brews, and needed hot water temperature is also different.For asking health, water need be boiled after rising and be incubated again, although existing electronic type or mechanical temperature regulating electric water heater tool can be realized temperature and arbitrarily regulate, but the temperature of operated by rotary motion is exactly heatable maximum temperature, water can not be boiled and rises, and its circuit structure is complicated, indicates not obvious.
Summary of the invention
The purpose of this utility model is the defect existing for prior art, provides that a kind of energy is simple in structure, holding temperature is adjustable, heating and thermal insulation is indicated clear and definite electric water heater.
For achieving the above object, the utility model adopts following technical proposals: a kind of electric water heater, comprise electric heater unit, temperature controller and electric connector with thermometal heat-sensitive sheet, electric connector is suppressed and is contacted by both contacts with the thermometal heat-sensitive sheet on temperature controller, be connected in electric heater unit electricity loop, also comprise thermosistor, switch, burner on light branch road and insulation pilot lamp branch road, in described temperature controller, be provided with independently heating and thermal insulation switching signal line, described switch one end connects heating and thermal insulation switching signal line, the other end serial connection electric heater unit of switch, one end of described thermosistor is connected between electric connector and temperature controller, the other end of thermosistor is connected to the joint of switch and electric heater unit, described insulation pilot lamp branch road comprises the first resistance, the first neon lamp being in series with the first resistance, insulation pilot lamp branch circuit parallel connection is in thermosistor two ends, described burner on light branch road comprises the second resistance, the second neon lamp being in series with the second resistance, described burner on light branch circuit parallel connection is in electric heater unit two ends.
As a kind of improvement: the joint by extended independent heating insulation switching signal line in temperature controller has male and female terminal concurrently.
Adopt the electric water heater of such scheme, by in temperature controller independently heating and thermal insulation signal wire control switch, at electric water heater heating boiling part, be that switch is closed, thermosistor and insulation pilot lamp branch road are by short circuit, the first neon lamp is not worked, the work of burner on light branch road, the second neon lamp indication electric water heater is in heated condition; When electric water heater is incubated, switch disconnects, if during the temperature that fluid temperature is set higher than thermosistor, thermosistor disconnects, the work of insulation pilot lamp branch road, and heating branch road pilot lamp branch road is not worked, and the first neon lamp is lighted indication keeping warm mode; If during the temperature that fluid temperature is set lower than thermosistor, thermosistor energising, insulation pilot lamp branch road is not worked by short circuit, electric heater unit heating, the work of heating branch road pilot lamp branch road, the second neon lamp is lighted indication heated condition.The first neon lamp and the second neon lamp can not worked simultaneously, the duty of knowing electric water heater that people can be perfectly clear, and its circuit structure is simple, reasonable, is easy to realize.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
As shown in Figure 1, a kind of specific embodiment of the utility model electric water heater, comprises electric heater unit M, the temperature controller II with thermometal heat-sensitive sheet, electric connector I, thermosistor WK1, switch K1, burner on light branch road and insulation pilot lamp branch road.Electric connector I is suppressed and is contacted by both contacts with the thermometal heat-sensitive sheet in temperature controller II, is connected in electric heater unit electricity loop.In described temperature controller II, be provided with independently heating and thermal insulation switching signal line, for easy to connect, the joint of the present embodiment heating and thermal insulation switching signal line has male and female terminal (being sign in figure) concurrently.Described switch K1 one end connects heating and thermal insulation switching signal line, the other end serial connection electric heater unit M of switch K1, an end of described thermosistor WK1 is connected between electric connector I and temperature controller II, the other end of thermosistor WK1 is connected to the joint of switch K1 and electric heater unit, described insulation pilot lamp branch road comprises the first resistance R 1, the the first neon lamp L1 being in series with the first resistance, insulation pilot lamp branch circuit parallel connection is in thermosistor WK1 two ends, described burner on light branch road comprises the second resistance R 2, the the second neon lamp L2 being in series with the second resistance R 2, described burner on light branch circuit parallel connection is in electric heater unit two ends.The first resistance R 1 in the present embodiment and the resistance of the second resistance R 2 are 120K Ω left and right.
Its principle of work: in temperature controller II, independently heating and thermal insulation signal wire is controlled switch K1.At electric water heater heating boiling part, be that switch K1 is closed, thermosistor WK1 and insulation pilot lamp branch road are by short circuit, and the first neon lamp L1 does not work, the work of burner on light branch road, and the second neon lamp L2 indication electric water heater is in heated condition.When electric water heater is incubated, switch K1 disconnects, if during the temperature that fluid temperature is set higher than thermosistor WK1, thermosistor WK1 disconnects, the work of insulation pilot lamp branch road, the first neon lamp L1 work, heating branch road pilot lamp branch road is because the resistance of electric heater unit M is 30 Ω left and right, the voltage difference at electric heater unit M two ends is too low, cannot make the second neon lamp L2 energising light, thus the second neon lamp L2 in extinguishing state, the first neon lamp L1 lights indication keeping warm mode; If during the temperature that fluid temperature is set lower than thermosistor WK1, thermosistor WK1 energising, insulation pilot lamp branch road is not worked by short circuit, electric heater unit M heating, the work of heating branch road pilot lamp branch road, the second neon lamp L2 lights indication heated condition.More clear for indication, the first neon lamp L1 and the second neon lamp L2 can adopt the neon lamp of two kinds of different colours.Electric water heater of the present utility model is owing to adopting independently heating and thermal insulation signal wire to control switch, realize water boil rise after in insulation, avoided the situation that repeats to boil, more health, health.Simultaneously the first neon lamp L1 in circuit and the second neon lamp L2 under normal circumstances not can with time light, the duty of knowing electric water heater that people can be perfectly clear, and simple and reasonable for structure, is easy to realize.
