Abstract

The invention relates to an anti-dry burning device of a water fountain. The anti-dry burning device comprises a drinking bucket, wherein an electric heater is installed below the drinking bucket and is electrically connected with a power supply, a bimetallic strip is electrically connected to the other end of the electric heater and is electrically connected with a temperature control contact which is electrically connected with a electromagnetic relay, the electromagnetic relay is electrically connected with the power supply, the upper part of the bimetallic strip is installed in a ceramic cover which is installed on the right side of the electric heater, and the lower part of the bimetallic strip is installed in the middle of a bimetallic strip seat. According to the anti-dry burning device, thermal expansion of the bimetallic strip is mainly utilized to deform, so as to solve the problem, and the bimetallic strip and the electromagnetic relay have double poweroff switching functions, so that the safety and the reliability of the anti-dry burning device are improved. By using the anti-dry burning device, the safety of the water fountain can be guaranteed, and dry burning cannot occur even if no water exists.

Description

Anti-parching device for drinking device
One, technical field
The present invention relates to a kind of safe drinking machine apparatus, relate in particular to a kind of anti-parching device for drinking device of connect bimetal leaf and electromagnetic relay in water dispenser electric heater circuit.
Two, background technology
The water dispenser that sell in market is now without anti-dry burning device, and after the current of water dispenser are done, heater can work on, and causes water dispenser to damage.
Three, summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of anti-parching device for drinking device of connect in water dispenser electric heater circuit bimetal leaf and electromagnetic relay is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-parching device for drinking device, comprise scuttlebutt, electric heater is installed below scuttlebutt, electric heater electric connection of power supply, electric heater other end is electrically connected to bimetal leaf, bimetal leaf is electrically connected to temperature control contact, temperature control contact is electrically connected to electromagnetic relay, electromagnetic relay electric connection of power supply, and the top of bimetal leaf is arranged in ceramic shield, ceramic shield is arranged on electric heater right edge, and the bottom of bimetal leaf is arranged in the middle of bimetallic bar.
The invention has the beneficial effects as follows, the present invention mainly utilizes bimetal leaf thermal expansion generation deformation, effectively addresses this problem, and bimetal leaf and electromagnetic relay have dual cut-off switch effect, increase security of the present invention, reliability.The present invention can guarantee water dispenser safety, even anhydrous, also can not burn out.
Four, accompanying drawing explanation
Below in conjunction with drawings and Examples, further illustrate the structure and characteristics of anti-parching device for drinking device of the present invention, in accompanying drawing:
Fig. 1 is the structure chart of embodiments of the invention one.
1. power supplys in figure, 2. electric heater, 3. scuttlebutt, 4. ceramic shield, 5. bimetal leaf, 6. temperature control contact, 7. electromagnetic relay, 8. bimetallic bar.
Five, the specific embodiment
In the embodiment shown in fig. 1, be provided with power supply (1), electric heater (2), scuttlebutt (3), ceramic shield (4), bimetal leaf (5), temperature control contact (6), electromagnetic relay (7), bimetallic bar (8).
Implement anti-parching device for drinking device of the present invention, a kind of anti-parching device for drinking device, comprise scuttlebutt (3), it is characterized in that, electric heater (2) is installed below described scuttlebutt (3), electric heater (2) electric connection of power supply (1), electric heater (2) other end is electrically connected to bimetal leaf (5), bimetal leaf (5) is electrically connected to temperature control contact (6), temperature control contact (6) is electrically connected to electromagnetic relay (7), electromagnetic relay (7) electric connection of power supply (1), the top of bimetal leaf (5) is arranged in ceramic shield (4), ceramic shield (4) is arranged on electric heater (2) right edge, the bottom of bimetal leaf (5) is arranged in the middle of bimetallic bar (8).
Implement anti-parching device for drinking device of the present invention, the present invention mainly utilizes bimetallic temperature control sheet thermal expansion generation deformation, effectively addresses this problem, and bimetal leaf and electromagnetic relay have dual cut-off switch effect, increase security of the present invention, reliability.The present invention can guarantee water dispenser safety, even anhydrous, also can not burn out.
Bimetallic temperature control sheet of the present invention top is wrapped in by circular ceramic shield, and contact point is connected when not working.Wire enters ceramic shield by minimum aperture from the side, connects electromagnetic relay discharge cock and bimetal leaf.The size in the hole in ceramic shield will be tried one's best little and need to be done encapsulation process, and anti-sealing enters ceramic shield.Electromagnetic relay is at the also disconnecting circuit simultaneously of bimetal leaf deformation disconnecting circuit, thereby prevents from causing because bimetal leaf recovers deformation that circuit is again closed weakens burning prevention function.Again, after supplying water to water dispenser, people be the electromagnetic relay discharge cock that closes, the circuit state of resuming work, thus avoid the generation of dry combustion method phenomenon.
Operation principle of the present invention: the difference of utilizing the expansion rate of different-alloy, when there is dry combustion method in excess Temperature, alloy sheet is to lopsidedness, after power-off, electromagnetic relay switch is in off-state, until after again supplying water to water dispenser, people is the relay switch that closes, circuit is again in running order, thereby avoids dry combustion method phenomenon to occur.And under normal circumstances, due to the heat conduction with water, its temperature can not reach the control temperature of setting, circuit is normally worked, and does not affect the heating of water.
Implement the present invention, effect is fine.
