Description
Technical field
The present invention relates to electric heater, particularly a kind of electric heater that is used for Fast Heating liquid, the improvement that belongs to existing electric heater is technological.
Background technology
The electrical heating product that present specialty is used for liquid heat has for example products such as water dispenser, insulating pot, electric water bottle, electric water boiler; These products all are in heating chamber, to place a lot of water in advance; Whole water with the inside heat fully then; Like this, hot water if desired is not a lot, obviously is to waste energy.
Therefore, the someone proposes, and heating chamber is separated with storage tank, wants to burn how much water and just burns how much water, and storage tank separates with heating chamber, when needs add hot water, through water pump with the water pump in the storage tank in heating chamber, need how much water, with regard to how much water of pump.Can reach certain energy-saving effect.
But for above-mentioned heater, the operating power of thick film heater is fixed, and can not regulate its operating power automatically according to the variations in temperature of water to be heated.Because the temperature of water tank is different in different places, under different seasonal and different state of weather, temperature differs and possibly reach about 20 degree; In when heating, the variation that thick film heater can't the perception water temperature is still heated according to certain power; Like this, when temperature is low, original water temperature is crossed when low; Firing rate is slow, and the temperature of water possibly not reach the requirement that requires the user.
The utility model content
The objective of the invention is to address the above problem and provide a kind of can be according to water temperature with the power adjusting of thick film heater to making the water can boiled fast value, make it to satisfy the electric heater of the temperature that quickly heats up to customer requirements.
The technical scheme that realizes the object of the invention is: a kind of electric heater, comprise control circuit, water tank, water pump, the thick film heater that has water inlet and delivery port and faucet, and water tank is connected through water pipe with water pump; The delivery port of water pump is connected with the water inlet of thick film heater; The delivery port of thick film heater is connected with an end of faucet and water return pipeline, and the other end of water return pipeline is connected with water tank, and water return pipeline is provided with the effluent recycling gauge tap; The effluent recycling gauge tap is electrically connected with control circuit; At least one temperature sensor is set on the electric heater, and temperature sensor is connected with control circuit, and faucet and reflux line all are arranged at the below of delivery port; And the delivery port of said reflux line is lower than the water inlet of reflux line; The tube wall of reflux line is provided with a through hole, and said through hole is near described delivery port, and said faucet is connected with delivery port through said through hole; Said delivery port is positioned at the bottom of thick film heater, and the position of said water inlet is higher than the position of delivery port.Temperature sensor is used to monitor the inner or peripheral water temperature of electric heater thick film heater, and water temperature is fed back to control circuit, realizes the adjusting control to the thick film heater heating power; Heating needn't be used water pump after finishing, and the residual water in the heater just can be back in the water tank through reflux line automatically; The position of the water inlet of thick film heater is higher than the position of its delivery port, then can the heating edge water outlet while intaking.
Above-mentioned water pump also is connected with control circuit, to realize the control of control circuit to the thick film heater inflow.
For safety, avoid thick film heater generation dry combustion method, in the bottom of thick film heater an anti-dry thermistor is set also, it is electrically connected with control circuit.Be used to monitor the surface temperature of thick film heater, prolong the service life of thick film heater.
The invention has the beneficial effects as follows that because temperature sensor is set on heater, the operating power of thick film heater becomes and can control, and can carry out work according to user's needs, not only product is safer, uses also more convenient.When the water temperature of water tank is crossed when low; The temperature signal that temperature sensor will get into the water of thick film heater is delivered to control circuit; Control circuit according to program with the power adjusting of thick film heater to making the water can boiled fast value, make it the constant requirement of satisfied temperature.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is that circuit of the present invention connects sketch map.
Fig. 3 is that of the present invention another implemented structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment concrete real-time mode of the present invention is described further.
Embodiment 1:
As shown in Figure 1; In the present embodiment; Electric heater comprises control circuit 9, water tank 1, water pump 2, the thick film heater 4 that has water inlet 5 and delivery port 8, effluent switch 6 and faucet 7, and water tank 1 and water pump 2 are connected through water pipe, and the delivery port of water pump 2 is connected with the water inlet 5 of thick film heater 4; Effluent switch 6 is installed on the delivery port 8 of thick film heater 4, and effluent switch 6 is communicated with faucet 7.In practical implementation; Effluent switch 6 adopts magnetic valve; Two thermistors 3 are separately positioned on the position of water inlet 5 and delivery port 8 of thick film heater 4; An anti-dry thermistor 3 is located at thick film heater 4 bottom (not shown)s, and three thermistors 3 and effluent switch 6 are electrically connected with control circuit 9 respectively.Can know the direction of current and being connected of each part clearly from Fig. 1, in the time of in being placed on these parts on any shell that designs, just form actual product.
It is as shown in Figure 2 that circuit of the present invention connects sketch map; Control circuit comprises input power supply L/N; This power supply is used to supply with central control unit through voltage of circuit such as reduction voltage circuit output, because of reduction voltage circuit and central control unit belong to the mature technology of household appliances product, so do not give unnecessary details.
The flow direction of current was when the present invention worked: the user is placed on water in the storage tank 1, and through the effect of water pump 2, the water in the water tank 1 is extracted in the thick film heater 4 by water pump 2; Then; Slowly flow in the pipeline of these water in thick film heater 4, the shape of pipeline can be spiral, also can be linear; Can realize easily that the present invention does not give unnecessary details by prior art; Water in the thick film heater 4 gets into effluent switch 6 from its outlet then; Water inlet thermistor 3 passes to control circuit 9 with the temperature value that records; Control circuit 9 sends signal the power of thick film heater 4 is regulated; In addition, delivery port thermistor 3 passes to control circuit 9 with the temperature value that records, when its temperature that records meets the demands; Effluent switch 6 is opened, and boiling water flows to faucet 7 backs from effluent switch 6 outlets and flows out.
Above-mentioned thick film heater 4 is that heating resistance wire is imprinted on stainless iron or stainless steel surfaces, energising back Fast Heating, and its thermal efficiency and security are more taller than common heat-generating pipe, therefore, have at present to begin to be applied on the insulating pot.
