Abstract
The invention discloses an improved structure of a water inlet joint of a water heater. The improved structure comprises a joint body, wherein a water inlet end and a water outlet end, which are communicated with each other by a runner, are arranged in the joint body; a permanent magnet wrapped by a seal body is arranged in the runner; and a magnetic sensor for sensing the permanent magnet is arranged on the outer wall of the joint body and is electrically connected with a switch of the water heater. The improved structure senses the permanent magnet in the runner through the magnetic sensor on the outer wall of the joint body and controls the switch of the water heater. The permanent magnet is insusceptible to field failure, covered by the seal body and protected from being corroded by water, so that a sensing device is difficult to fail even the joint is used for a long time; the safety and reliability are greatly improved; and the water heater is effectively prevented from being dried out.
Description
Technical field
The present invention relates to the water heater joint.
Background technology
For preventing the water heater dry combustion method, water heater all is provided with anti-dry burning device.Existing water heater anti-dry burning device is located on the water heater joint.Its concrete structure is for being provided with a plug in the runner of joint body, outside joint body, be provided with infrared sensing device, when in the water heater water being arranged, because the effect of hydraulic pressure, water in the water heater can promote plug and depart from the infrared sensing device position, the water heater operate as normal.When in the water heater during lack of water, hydraulic pressure reduces in the water heater, and plug will return stops the infrared ray of infrared sensing device, closes thereby infrared sensing device will send the signal controlling heater switch.But, in this kind anti-dry burning device infrared sensing device rely on transparent joint could the perception plug, in case the water heater joint is long-term use after, the color relation of joint can turn to be yellow, and makes the infrared sensing device can not the perception plug.Thereby reliability and security are all good inadequately.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of reliability and all better water heater water supply connectors of security, prevents the water heater dry combustion method.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the water heater water supply connector improves structure, comprise joint body, be provided with runner in the described joint body and connect water inlet end and water side, it is characterized in that: be provided with permanent magnet in the described runner with the seal parcel, described joint body outer wall is provided with the Magnetic Sensor of perception permanent magnet, and described Magnetic Sensor is electrically connected with the heater switch.
As preferably, described joint body is provided with ground terminal, and ground terminal the inner is stretched in the runner, and the outer end connects earth connection.Play the earth leakage protective effect.
As preferably, described joint body is provided with the pressure release valve opening that is communicated with runner.
As preferably, described Magnetic Sensor is located on the sensor stand, and described joint body is provided with the flank of expansion, described sensor stand by bolting on described flank.Be convenient to install.
As preferably, the screw plug that has been threaded on the described water inlet end, described screw plug center is provided with the orthohexagonal hole for the inner hexagon spanner effect.Unloading screw plug is replaceable permanent magnet, has overcome existing structure and has pulled down the drawback that whole joint could be changed permanent magnet from the water side from water heater.
The present invention is by the permanent magnet in the Magnetic Sensor perception runner on the joint body outer wall and control the heater switch, and permanent magnet is difficult for loss of excitation, and there is seal to coat the erosion that can not be subjected to water, even thereby joint uses for a long time, sensing device also is difficult for losing efficacy, security and reliability greatly improve, and effectively prevent the water heater dry combustion method.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is a structural representation of the present invention (Magnetic Sensor is not installed);
Fig. 2 is the sensor stand schematic diagram;
Fig. 3 is the screw plug structural representation.
The specific embodiment
As shown in Figure 1 to Figure 3, improve the embodiment of structure for water heater water supply connector of the present invention, comprise joint body 1, be provided with runner 13 in the described joint body and connect water inlet end 11 and water side 12, be provided with permanent magnet 2 in the described runner with seal 21 parcels, described joint body outer wall is provided with the Magnetic Sensor 3 of perception permanent magnet, and described Magnetic Sensor is electrically connected with the heater switch.Described joint body is provided with ground terminal 4, and ground terminal the inner is stretched in the runner, and the outer end connects earth connection.Described joint body is provided with the pressure release valve opening 5 that is communicated with runner.Described Magnetic Sensor is located on the sensor stand 6, and described joint body is provided with the flank 7 of expansion, described sensor stand by bolting on described flank.The screw plug 8 that has been threaded on the described water inlet end 11, described screw plug center are provided with the orthohexagonal hole 9 for the inner hexagon spanner effect.
Operation principle of the present invention is: when in the water heater water being arranged, the water in the water heater can promote permanent magnet and depart from the Magnetic Sensor position, and Magnetic Sensor does not act on, the water heater operate as normal.When in the water heater during lack of water, permanent magnet will be in the Magnetic Sensor position by return, closes thereby Magnetic Sensor will send the signal controlling heater switch.
