Abstract
The invention discloses a water inlet joint for a water heater. The water inlet joint comprises a joint body, wherein a runner which passes through a water inlet end and a water outlet end is arranged in the joint body; a magnet is arranged in the runner; a magnetic sensor for sensing the magnet is arranged on the outer wall of the joint body, and is electrically connected with the switch of the water heater. In the water inlet joint for the water heater, a plug and infrared sensing structure is changed into a magnetic transforming structure, the magnetic sensor on the outer wall of the joint body is used to sense the magnet in the runner and control the switch of the water heater, the sensing device cannot be failed even the joint is used for a long time, the safety and reliability can be greatly improved, and empty burning of the water heater is effectively prevented.
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, 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 magnet piece in the described runner, described joint body outer wall is provided with the Magnetic Sensor of perception magnet piece, 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.
The present invention changes plug and infrared sensing structure is the magnetic mutual inductance structure, by the magnet piece in the Magnetic Sensor perception runner on the joint body outer wall and control the heater switch, even 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.
The specific embodiment
Follow shown in Figure 2 as Fig. 1, embodiment 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 magnet piece 2 in the described runner, described joint body outer wall is provided with the Magnetic Sensor 3 of perception magnet piece, 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 13, 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.
Operation principle of the present invention is: when in the water heater water being arranged, the water in the water heater can promote magnet piece 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, magnet piece will be in the Magnetic Sensor position by return, closes thereby Magnetic Sensor will send the signal controlling heater switch.
