Abstract
The utility model relates to a full-automatic constant temperature electric water heater, comprising a water level sensor, a temperature sensor, an automatic control circuit board, an electric heater, a water inlet electromagnetic valve, etc. The utility model is characterized in that a logic circuit with optimum logical relationship is adopted; the water inlet and the heating keep the optimizing states; the rated power of the electric heater is reduced; the automatic control on water temperature and water level and the water with continuous supplying and constant temperature are realized; the water temperature is divided into the gears or is continuously adjustable; the electric heater is automatically protected, the alarm is automatically when the water pressure is insufficient, and the safety is automatically when the electricity is leaked. The utility model has safety, durability, electricity saving and convenient use, and is an ideal water heater for the situations of families, hotels, etc.
Description
A kind of electrical heating type constant-temperature hot water device with full-automatic function.
Enter hotel, family already as washing, the electric heater used of shower, existing electric heater is divided into two kinds of heat-storage and continuous-flows substantially, and the shortcoming of these two kinds of electric heaters is water temperature instabilities; The rated power of electric heater is too big, and (3000～5000W) is bigger than normal as the family expenses load; Careless slightlyly just can burn electric heater when causing lack of water.
The objective of the invention is to overcome above shortcoming, design a kind of electric heater of full rotation type, can control water temperature, water level in the tank automatically, protect electric heater automatically, hydraulic pressure is not enough reports to the police and the electric leakage automatic protecting automatically.
Another object of the present invention is in order to economize on electricity, 0.5～2 kilowatt of to make electric heater rated power about, supplying with the hot water of steady temperature continuously to be suitable for average family.
The utility model has the advantages that fairly obvious, safe, durable, economize on electricity, extremely easy to use.
Description of drawings:
Fig. 1 is the structural representation of fully-automatic thermostatic electric heater.
Fig. 2 is this utility model circuit controlling party block diagram.
1, level sensor; 2, temperature sensor; 3, the water level variable forms circuit; 4, temperature variable forms circuit; 5, logic circuit; 6, entering water electromagnetic valve; 7, electric heater; 8, electric leakage protector LB; 9, boiler alarm; 10, automatic control circuit board; 11, water receiver; 12, effluent switch.
As shown in Figure 1, this utility model is made up of following part: put one in the water receiver (11) and detect the temperature sensor (2) that water temperature is used; The level sensor (1) that sensed water level is used, wherein A is the water level upper limit, B is the water level lower limit; The electric heater with electrical insulation capability (7) that places the water receiver bottom; The injection of an entering water electromagnetic valve (6) control cold water; An electric water level variable forms the automatic control circuit board (10) of circuit (3), temperature variable formation circuit (4), logic circuit (5), boiler alarm (9) formation; The electric leakage protector of an incoming transport electrical network (8), an effluent switch (12). Dotted line is the water surface among the figure.
The utility model is to implement like this:
Adopt logic circuit to realize the dynamic control of two parameters.With the variation of the variation of water temperature and water level input logic variable as combinational logic circuit, and the output logical variable of combinational logic circuit is as driving signal, connect or close entering water electromagnetic valve and electric heater, can control the water yield and the heat that inject water receiver, reach the purpose of confessing constant-temperature hot water continuously.In addition for further guarantee safety for the purpose of, set up an electric leakage protector.
For the ease of understanding and implementing the present invention, the input of logic circuit, the setting and the logical expression of output variable are done following explanation:
Setting two water level input logic variables is X and Y:
When water level is lower than B, X=1
When water level is higher than B, X=0
Below water level is in lower limit B and water level below B when rising and be not raised to upper limit A as yet, Y=1,
When water level rises to A, and water level from A when descending and do not drop to lower limit B as yet, Y=0.

Because output state and input state have suitable logical relation, water inlet can compensate mutually with heating, and electric heater needn't be got very big rated power, can keep the duty of an optimization.
Boiler alarm (9) is arranged on the low water level point of level sensor (1), and when the tap water pressure deficiency, or brownout is when having little time to heat required hot water, and water receiver is in exsiccosis, and water level is reduced to below the B, and lack of water is reported to the police automatically.
Chatted as seen by above institute, this utility model circuit is simple, assembly and adjustment convenient, and is stable and reliable for performance, extremely easy to use.
