Abstract
The utility model relates to a full-intelligent electric kettle, which is characterized in that the electric kettle is also provided with a water level probe; the position of the water level probe is high than the electric heating pipe; and the water level probe and the control circuit are electrically connected. In case the water level probe tests out water, the water level detection circuit controls the primary electric relay to switch on and then the heating pipe, the heat-sensitive electric relay are communicated with the power supply and the heating pipe begins to work. In case the water level probe tests out no water, the water level detection circuit controls the primary electric relay to switch off and then the heating pipe, the heat-sensitive electric relay are disconnected from the serial loop composed of the power supply and the heater stops working. The utility model has the advantages that the kettle can identify the water level and can automatically make heat preservation; the use is safe and practical; the service life of the electric heating pipe is extended and the life and property safety is protected.
Description
Technical field:
The utility model relates to a kind of insulating pot, particularly a kind of circuit of complete intelligent insulating pot control.
Background technology:
Though the insulating pot of family expenses has some that protective device has been installed at present; but function imperfection; particularly forget discharge water and water boil after when continuing to hot plate; because water evaporates causes water level to be lower than electrothermal tube; cause heater to burn out; destroyed insulator, be easy to cause electric shock accidents, and serious fire incident has taken place.
Summary of the invention:
The purpose of this utility model is a kind of complete intelligent insulating pot, and this insulating pot can be discerned water level, automatic heat preserving.
To achieve these goals, the technical solution of the utility model is as follows: complete intelligent insulating pot, comprise the insulating pot body, be provided with electrothermal tube in the insulating pot body, the shell of this thermal relay and insulating pot is close to setting, and this insulating pot is provided with control circuit, this control circuit is electrically connected with electrothermal tube, thermal relay and power supply, it is characterized in that also being provided with water-level probe in this insulating pot, the position of water-level probe is higher than electrothermal tube, and this water-level probe is electrically connected with control circuit.
This control circuit comprises the lower pressure rectifier circuit that is connected with power supply, the output of this lower pressure rectifier circuit is connected with water level detection circuit, the input of water level detection circuit is connected with water-level probe, the output of water-level detecting circuit is connected with the control end of first relay, and the normal open switch of first relay and heating tube and thermal relay are connected in series in the two ends of power supply.This control circuit also comprises the warning circuit that is connected with water level detection circuit.
After connecting power supply, the power supply of this complete intelligent insulating pot is input as alternating current, and the transformation rectification of process lower pressure rectifier circuit forms low tension and offers water level detection circuit.When if water-level probe has detected water, the water-level detecting circuit is controlled the first relay adhesive, then heating tube, thermal relay and power connection, heating tube work.After poach is opened, because thermal relay is close to the kettle shell, so the thermal relay disconnection, heating tube quits work.If water-level probe detects when anhydrous, then the water-level detecting circuit is controlled first relay and is disconnected, the then series loop disconnection formed of heating tube, thermal relay and power supply, so heater is not worked.Therefore advantage of the present utility model is that it can discern water level, and can automatic heat preserving, and is safe and practical, can prolong the physical life of electrothermal tube, can protect life safety and property safety again.
Description of drawings:
Fig. 1 is a structure chart of the present utility model
Fig. 2 is a circuit diagram of the present utility model
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated.
Complete intelligent insulating pot, comprise insulating pot body 1, be provided with electrothermal tube 2 in the insulating pot body 1, it is characterized in that also being provided with water-level probe 4 in this insulating pot 1, the position of water-level probe 4 is higher than electrothermal tube 2, and this insulating pot 1 also is provided with control circuit 3, this control circuit 3 and water-level probe 4, electrothermal tube 2, and power supply 5 be electrically connected, this control circuit 3 also is electrically connected with thermal relay 6, and this thermal relay 6 is close to setting with the shell of insulating pot 1.
This control circuit 3 comprises the lower pressure rectifier circuit 7 that is connected with power supply 5, the output of this lower pressure rectifier circuit 7 is connected with water level detection circuit 8, the input of water level detection circuit 8 is connected with water-level probe 4, the output of water-level detecting circuit 8 is connected with the control end of first relay J 1, and the switch of first relay J 1 and heating tube 2 and thermal relay 6 are connected in series in the two ends of power supply 5.This control circuit 3 also comprises the warning circuit 9 that is connected with water level detection circuit 8.
In the utility model, control circuit 3 and water-level probe 4 all are arranged on the avris of kettle, can with the supporting use of present original insulating pot, water-level probe constitutes with stainless steel and outer insulator.Thermal relay 6 is close to the installation of the kettle outside, and along with the cold and hot variation of water temperature, the temperature-sensitive steel disc carries out folding and switches when to boil water, thus the control water temperature.
The circuit diagram of an embodiment of the utility model control circuit has been shown among Fig. 2.As can be seen, the output voltage of lower pressure rectifier circuit 7 by 3 shuntings of resistance R 2, resistance R after, make triode B8 conducting, thereby make triode B9 conducting, 1 adhesive of first relay J, so the series circuit conducting of heating tube 2, thermal relay 6 and power supply 5 compositions, heating tube 2 work.The first indicator lamp LED1 simultaneously in parallel with thermal relay 6 lights.After poach was opened, thermal relay 6 disconnected, and heating tube 2 is not worked, and at this moment, the second indicator lamp LED2 in parallel with heating tube also lights.When being reduced to water-level probe 4 as unattended water level, triode B8 and all not conductings of B9, therefore first relay J 1 disconnects, and therefore heating tube 2, thermal relay 6 disconnect with the series circuit that power supply 5 is formed, and heating tube 2 is not worked.At this moment, indicator lamp LED3 is bright, and indicator lamp LED1 and LED2 are dark.In the present embodiment, this control circuit 3 also comprises the warning circuit 9 that is connected with water level detection circuit 8.At this moment, these warning circuit 9 conductings, buzzer 10 work.
