Abstract
The utility model relates to a kind of safety electric immersion heater detecting the water yield, has can detect the water yield in vacuum flask and whether reach requirement water level, if water shortage can be stopped power supply and the feature of reporting to the police automatically.Comprise a depth of water checkout gear and a warning circuit in immersion heater, depth of water checkout gear comprises switch, relay, metal tube, insulated tube, connecting rod and kickboard, and warning circuit comprises normally closed switch, warning electric bell and alarm lamp.When the water yield reaches standard, kickboard float, on metal tube contact electrode heater circuit is communicated with, when the water yield does not reach standard, electrode is intercepted by insulated tube and makes heater circuit become open circuit, and the warning circuit under Control is connected, and warning device gives the alarm.The utility model compensate for the shortcoming that traditional immersion heater can not detect the water yield, allows immersion heater auto-breaking reporting to the police when water shortage, thus avoid immersion heater dry combustion method that water level deficiency causes and set off an explosion, the danger such as fire.
Description
Technical field
The utility model provides a kind of safety electric immersion heater that can detect the water yield, has can detect the water yield in vacuum flask and whether reach requirement water level, if water shortage can be stopped power supply and the feature of reporting to the police automatically.
Background technology
At present, whether the immersion heater of conventional domestic can not detect the water yield up to standard, is easy to cause dry combustion method, causes short circuit, cause the risk of fire if heated up water with immersion heater when water level will not reach requirement height.
Summary of the invention
In order to ensure the safety of immersion heater further, reduce water level deficiency and cause the hidden danger of bringing out fire when dry combustion method, this practicality provides a kind of immersion heater, this immersion heater energy sensed water level height, if the water yield crosses that I haven't seen you for ages automatic shutoff circuit, stop power supply, and give the alarm.Doing so avoids the water level immersion heater dry combustion method that causes of deficiency and set off an explosion, the danger such as fire.
The invention for solving the technical problem take scheme be: in immersion heater, design a depth of water checkout gear and a warning circuit, depth of water checkout gear comprises switch, relay, metal tube, insulated tube, connecting rod and kickboard, and warning circuit comprises normally closed switch, warning electric bell and alarm lamp.When the water yield reaches standard, kickboard is bubbled through the water column, and heads on connecting rod rising, the metal tube contact electrode on connecting rod, and connect heater circuit, the relay of connecting with electrode is started working, and the normally closed switch under Control disconnects, and warning circuit disconnects; Otherwise, when the water yield do not reach necessarily require time, connecting rod lifting height is not enough to make metal tube contact electrode, electrode is intercepted by insulated tube, heater circuit is in off state, and the relay of connecting with electrode quits work, and the normally closed switch under Control closes, connect warning circuit, warning device gives the alarm.
The beneficial effects of the utility model are: compensate for the shortcoming that traditional immersion heater can not detect the water yield, allow immersion heater auto-breaking reporting to the police when water shortage, thus avoid immersion heater dry combustion method that water level deficiency causes and set off an explosion, the danger such as fire.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the overall structure figure of immersion heater.
Fig. 2 is the depth of water checkout gear of immersion heater and the structure chart of warning circuit.
Fig. 3 is the circuit theory diagrams of immersion heater.
1. traditional immersion heaters, 2. depth of water checkout gear, 3. switch in figure, 31. electrodes, 32. wires, 33. relays, 34. warning circuits, 341. normally closed switchs, 342. warning electric bells, 343. alarm lamps, 4. connecting rod, 41. metal tubes, 42. insulated tubes, 5. kickboard.
Embodiment
As Fig. 1, overall structure figure of the present utility model can be seen.The utility model comprises traditional immersion heater (1) and depth of water checkout gear (2), depth of water checkout gear (2) is connected with the head of traditional immersion heater (1), and parallel with the resistance wire of traditional immersion heater (1).
As Fig. 2, the structure chart of depth of water checkout gear of the present utility model and warning circuit can be seen.Warning circuit (34) comprises normally closed switch (341), warning electric bell (342) and alarm lamp (343), and normally closed switch (341) is subject to the control of relay (33); Depth of water checkout gear (2) comprises switch (3), electrode (31), wire (32), relay (33), connecting rod (4), metal tube (41), insulated tube (42) and kickboard (5), metal tube (41) and insulated tube (42) are positioned at connecting rod (4) upper end, kickboard is positioned at connecting rod lower end, and the electrode (31) on switch (3) is enclosed within metal tube (41) and insulated tube (42).When the water yield reaches standard, kickboard (5) is bubbled through the water column, and head on connecting rod (4) rising, metal tube (41) contact electrode (31) on connecting rod (4), connect circuit, the relay (33) of connecting with electrode (31) is started working, and the normally closed switch (341) under relay (33) controls disconnects, and warning circuit (34) disconnects; Otherwise, when the water yield do not reach necessarily require time, connecting rod (4) lifting height is not enough to make metal tube (41) contact electrode (31), electrode (31) is intercepted by insulated tube (42), circuit is in off state, the relay (33) of connecting with electrode quits work, normally closed switch (341) under relay (33) controls closes, connect warning circuit (33), warning device gives the alarm.
As Fig. 3, circuit theory diagrams of the present utility model can be seen.Overall work circuit is divided into two branch roads, first branch road there are fast (1) and the depth of water checkout gear (2) of tradition heat, in depth of water checkout gear (2), the part of place in circuit is switch (3) and relay (33), second branch road is warning circuit (34), this branch road has the normally closed switch (341), warning electric bell (342), the alarm lamp (343) that control by relay (33).When the depth of water reaches requirement, switch (3) on first branch road closes, and traditional immersion heater (1) is started working, and relay (33) is started working, and the normally closed switch (341) disconnected on the second branch road, the second branch road disconnects.When the depth of water does not reach requirement, switch (3) on first branch road disconnects, tradition immersion heater (1) quits work, relay (33) quits work, normally closed switch (341) on second branch road recovers closed, second branch road is connected, and warning electric bell (342) and alarm lamp (343) are started working, and give the alarm.
