Abstract
The utility model relates to an automatic power-off device for an electric water heater. The automatic power-off device for an electric water heater is characterized in that one magnet is connected with a gas gathering device inside the electric water heater, and the other magnet is connected with a power-off device outside the electric water heater, resulting in that the two magnets inside and outside of the electric water heater are mutually attracted on the bottom of the electric water heater. The magnet inside the electric water heater is driven to move because of the upward float of the gas gathering device when the water is boiled, resulting in that the magnet outside the electric water heater loses the magnetic force and falls under the action of gravitation and elasticity, and then the power supply is cut off, realizing automatic power-off.
Description
The utility model is a kind of electrical heating water heater auto-power-off device.
At present the insulating pot that generally uses can not cut off the power supply when water is opened automatically, needs the people in time to cut off the electricity supply after water is opened during use, uses very inconveniently, and the boiled back of water is not in time found sometimes, and water is dryouied, and causes electric heater to burn.
The purpose of this utility model is that a kind of electrical heating water heater auto-power-off device will be provided, and it is applicable to insulating pot and electric water tank and other electrical heating water heater, can cut off the power supply automatically when water is opened.
The purpose of this utility model is achieved in that in the electrical heating water heater collection vapour device is connected with a magnet, outside the electrical heating water heater, a breaker device is connected with another magnet, inside and outside two magnets of electrical heating water heater are attracted each other on electrical heating water heater bottom surface, when water is opened, collection vapour device come-up, the magnet that drives in the electrical heating water heater moves, and makes the outer magnet of electrical heating water heater lose magnetic force, under the effect of gravity, elastic force, fall, cut off the electricity supply.
Because the utility model is simple in structure, cheap, can improve the performance of insulating pot, electric water tank.
Accompanying drawing is the profile according to the automatic outage electrical heating water heater that the utility model proposes.Automatic outage electrical heating water heater shown in Figure 1 is the state that is in after filled with water is connected power supply.Automatic outage electrical heating water heater shown in Figure 2 is the state that is in after water is opened the automatic cut-out of back power supply.
Below in conjunction with accompanying drawing the utility model is further described.
Shown in the figure (1): the electrical heating water heater of forming by water heater (1) and electric heater (2), collection vapour device in water heater (1) is that the end by lever (6) is connected with water heater (1) hinge, the other end of lever (6) and vapour collect cover (4) are affixed, open on the top of vapour collect cover (4) that an aperture (5) constitutes.The middle part of lever (6) or end and magnet (7) are affixed.Breaker device outside water heater (1) is an end protuberate basic unit (3) outside by lever (9), one end of the other end of lever (9) and spring [11] is affixed, the end of lever (9) is connected with base (3) hinge, the middle part of lever (9) or end are stuck on the normally closed interlock (10), normally closed interlock (10) is affixed with base (3), base (3) and the affixed formation of water heater (1).Magnet (8) is affixed with the other end of lever (9).
When in water heater (1), filling up water, air in the vapour collect cover (4) is discharged from aperture (5), press the lever (9) of protuberate basic unit outside, magnet (8) and magnet (7) are attracted each other on water heater (1) bottom surface, lever (9) breaks away from normally closed interlock (10), make normally closed interlock (10) closure, connect power supply, see Fig. 1.Before water is opened, after a small amount of water vapor of overflowing in the water constantly enters vapour collect cover (4), discharge by aperture (5).After water is opened, a large amount of water vapours of overflowing in the water constantly enter vapour collect cover (4), and wherein a part is discharged from aperture (5), because the water vapour amount in the vapour collect cover (4) of entering is greater than the water vapour amount of discharging from aperture (5), water vapour in the vapour collect cover (4) is on the increase, is made vapour collect cover (4) come-up.Effect is best down for the opening of aperture (5), can make vapour collect cover (4) be subjected to the recoil effect of aperture (5) discharge water steam like this, has increased the buoyancy of vapour collect cover (4).Because the come-up of vapour collect cover (4) makes lever (6) drive magnet (7) and upwards rotates, and makes magnet (8) lose magnetic force, falls under the effect of deadweight and spring [11], and normally closed interlock (10) is disconnected.Reach water and open the purpose of automatic outage, see Fig. 2.
The utility model also the magnet (7) in the water heater (1) can be replaced with ferromagnetic material or the magnet (8) that water heater (1) is outer replaces with ferromagnetic material.
Claims (4)
1, a kind of electrical heating water heater auto-power-off device, it is characterized in that the electrical heating water heater formed by water heater and electric heater, be connected with a magnet (7) by one in electrical heating water heater collection vapour device, the outer breaker device of electrical heating water heater is connected with magnet (8).
2, according to the described electrical heating water heater of claim 1 auto-power-off device, it is characterized in that collection vapour device in the electrical heating water heater is that a end by lever (6) is connected with electrical heating water heater hinge, the other end of lever (6) and vapour collect cover (4) are affixed, the middle part of lever (6) or end and magnet (7) are affixed, open on the top of vapour collect cover (4) that an aperture (5) constitutes.
3, according to the described electrical heating water heater of claim 1 auto-power-off device, it is characterized in that the outer breaker device of electrical heating water heater is an end protuberate basic unit (3) outside by lever (9), one end of the other end of lever (9) and magnet (8), spring (11) is affixed, the end of lever (9) is connected with base (3) hinge, the middle part of lever (9) or end are stuck on the normally closed interlock (10), normally closed interlock (10) is fixed on the base (3), base (3) and the affixed formation of electrical heating water heater.
4, according to the described electrical heating water heater of claim 2 auto-power-off device, the opening that it is characterized in that aperture (5) down.
