Abstract

The utility model discloses a dry-burning preventing device for a water dispenser. The dry-burning preventing device comprises a drinking water barrel, wherein an electric heater is arranged below the drinking water barrel and is electrically connected with a power supply; the other end of the electric heater is connected with double metal sheets; the double metal sheets are electrically connected with a temperature control contact; the temperature control contact is elastically connected with an electromagnetic relay; the electromagnetic relay is electrically connected with the power supply; upper parts of the double metal sheets are arranged in a ceramic cover; the ceramic cover is arranged on the right side of the electric heater; and lower parts of the double metal sheets are arranged at the middle of a double metal sheet seat. According to the dry-burning preventing device disclosed by the utility model, a problem is effectively solved by mainly using the deformation due to thermal expansion of the double metal sheets; and the double metal sheets and the electromagnetic relay have double functions of power cutting-off switches, and the safety and the reliability of the dry-burning preventing device are enhanced. The dry-burning preventing device disclosed by the utility model can ensure the safety of the water dispenser and is free from being burnt out even if the water dispenser is under the condition of no water.

Description

Anti-parching device for drinking device
One, technical field
The utility model relates to a kind of safe drinking machine apparatus, relates in particular to a kind of anti-parching device for drinking device of connect in water dispenser electric heater circuit bimetal leaf and electromagnetic relay.
Two, background technology
The water dispenser of market sale does not now have anti-dry burning device, and after the current of water dispenser were done, heater can work on, and causes water dispenser to damage.
Three, utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and 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 scheme that its technical problem that solves the utility model adopts is: a kind of anti-parching device for drinking device, comprise scuttlebutt, electric heater is installed below scuttlebutt, the electric heater electric connection of power supply, the electric heater other end is electrically connected bimetal leaf, bimetal leaf is electrically connected the temperature control contact, the temperature control contact is electrically connected electromagnetic relay, the electromagnetic relay electric connection of power supply, the top of bimetal leaf is installed in the ceramic shield, ceramic shield is installed in the electric heater right edge, and the bottom of bimetal leaf is installed in the middle of the bimetallic bar.
The beneficial effects of the utility model are, the utility model 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 utility model, reliability.The utility model can be guaranteed water dispenser safety, even anhydrous, also can not burn out.
Four, description of drawings
Below in conjunction with drawings and Examples, further specify structure and the characteristics of the utility model anti-parching device for drinking device, in the accompanying drawing:
Fig. 1 is the structure chart of embodiment one of the present utility model.
1. power supplys among the 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 utility model, 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 bimetal leaf (5), bimetal leaf (5) is electrically connected temperature control contact (6), temperature control contact (6) is electrically connected electromagnetic relay (7), electromagnetic relay (7) electric connection of power supply (1), and the top of bimetal leaf (5) is installed in the ceramic shield (4), ceramic shield (4) is installed in electric heater (2) right edge, and the bottom of bimetal leaf (5) is installed in the middle of the bimetallic bar (8).
Implement anti-parching device for drinking device of the present utility model, the utility model mainly utilizes bimetallic temperature control sheet thermal expansion generation deformation, effectively address this problem, bimetal leaf and electromagnetic relay have dual cut-off switch effect, increase security of the present utility model, reliability.The utility model can be guaranteed water dispenser safety, even anhydrous, also can not burn out.
Bimetallic temperature control sheet of the present utility model top is wrapped in by the ceramic shield of circle, and contact point links to each other when not working.Lead enters ceramic shield by minimum aperture from the side, connects electromagnetic relay discharge cock and bimetal leaf.The size in the hole on the ceramic shield will be tried one's best little and need 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 the circuit closed anti-dry miopragia that makes again because bimetal leaf recovers deformation.Again after supplying water to water dispenser, the 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 utility model: the difference of utilizing the expansion rate of different-alloy, when temperature is too high when namely dry combustion method taking place, alloy sheet is to lopsidedness, after the outage, the electromagnetic relay switch is in off-state, and after supplying water to water dispenser again, the people is the relay switch that closes, circuit is in running order again, thereby avoids the dry combustion method phenomenon to take place.And under normal circumstances, owing to conduct with the heat of water, its temperature can not reach the control temperature of setting, and the circuit operate as normal does not influence the heating of water.
Implement the utility model, effect is fine.
