Description
Technical field
The present invention relates to a kind of sensor, relate in particular to a kind of water heater water-level and water-temperature sensor, be mainly used in the equipment that detects water temperature and water level on the storage-type electric water heater.
Background technology
Now the sensor great majority on the market all are that liquid level sensor and temperature sensor separate, and have some can detect the sensor of liquid level and liquid temperature simultaneously but the complex structure price is more expensive, and practicality is not strong.Be difficult to find one to be applicable to and to control the sensor that temperature can be controlled liquid level again on the storage-type electric water heater; Storage-type electric water heater great majority on the therefore present market all do not have liquid level detection system; A lot of storage-type electric water heaters do not have can heat under the situation of water in courage yet, make water heater exist potential safety hazard.
Summary of the invention
My company has invented a kind of new sensor and is used for water-level and water-temperature and detects for this reason---the water heater water-level and water-temperature sensor; This sensor is mainly used in storage-type electric water heater; Can guarantee under water heater has the state of water, not heat; Thereby stopped the generation of the hot dry combustion method phenomenon of water heater, magnet controlled liquid level liquid temperature sensor is that the function with liquid level sensor and liquid temperature sensor is integrated in one, and the position that can detect liquid can detect the temperature value of liquid again; Advantages such as it is simple in structure, it is anti-oxidant to have, anticorrosion, less scaling, highly sensitive, stable performance, long service life also can be used for the detection and the control of other liquid simultaneously.
Technical scheme of the present invention to achieve these goals is to adopt following means to realize: a kind of water heater water-level and water-temperature sensor; Form by outer tube body, temperature sensor, floater guiding body, hold-down nut and silica gel pad; Described temperature sensor is installed in outer tube body bottom; Described outer tube body inside is equipped with magnetic switch and signal wire, is with upper limit jump ring, lower limit jump ring and floater guiding body on the described outer tube body, and described lower limit jump ring is installed in the lower end of upper limit jump ring.
Described floater guiding body is installed in the middle of lower limit jump ring and the upper limit jump ring; Described floater guiding body can move freely between lower limit jump ring and upper limit jump ring along outer tube body; Described floater guiding body inside is equipped with annular magnetic control body, and described magnetic control body is enclosed within on the outer tube body.
Described magnetic switch is arranged between lower limit jump ring and the upper limit jump ring near upper limit jump ring place.
Described signal wire connects temperature sensor and magnetic switch respectively, is used for transmission signals.
It is peripheral that described fixed screw and silica gel pad are installed in the outer tube body upper end.
The present invention has following remarkable advantages and beneficial effect:
1) has the measuring ability of liquid level and liquid temperature one;
2) simple in structure, advantage with anti-oxidant, anticorrosion, less scaling, highly sensitive, stable performance, long service life.

Embodiment
Shown in Fig. 1-3: a kind of water heater water-level and water-temperature sensor; Form by outer tube body 7, temperature sensor 1, floater guiding body 3, hold-down nut 8 and silica gel pad 9; Described temperature sensor 1 is installed in outer tube body 7 bottom, is used for the tracer liquid temperature, and described outer tube body 7 inside are equipped with magnetic switch 5 and signal wire 10; Be with upper limit jump ring 6, lower limit jump ring 2 and floater guiding body 3 on the described outer tube body 7; Described lower limit jump ring 2 is installed in the lower end of upper limit jump ring 6, and it is middle with upper limit jump ring 6 that described floater guiding body 3 is installed in lower limit jump ring 2, and described floater guiding body 3 can move freely between lower limit jump ring 2 and upper limit jump ring 6 along outer tube body 7; Described floater guiding body 3 inside are equipped with annular magnetic control body 4; Described magnetic control body 4 is enclosed within on the outer tube body 7, and described magnetic switch 5 is arranged between lower limit jump ring 2 and the upper limit jump ring 6 near upper limit jump ring 6 places, and described signal wire 10 connects temperature sensor 1 and magnetic switch 5 respectively; Be used for transmission signals, described fixed screw 8 is installed in periphery, outer tube body 7 upper ends with silica gel pad 9.
The present invention implements like this, at first with the water heater water-level and water-temperature sensor through fixed screw 8 with above silica gel pad 9 is installed in relevant equipment, have temperature sensor 1 one ends down; Floater guiding body 3 floats over water, and perhaps other are above liquid, and floater guiding body 3 can move up and down along with the position of liquid, only between lower limit jump ring 2 and upper limit jump ring 6, move; When liquid level rises; Floater guiding body 3 moves up until upper limit jump ring 6 places, and at this moment magnetic control body 4 just in time also moves up, and moves to and magnetic switch 5 close height places; At this moment magnetic control body 4 is because magnetic; With magnetic switch 5 closures, closure signal transfers to other equipment through signal wire 10, shows fluid level condition; When liquid level descended, floater guiding body 3 moved down, until moving to jump ring 2 places of rolling off the production line; At this moment magnetic control body 4 moves down equally, because magnetic control body 4 is away from magnetic switch 5, the magnetic of magnetic switch 5 is eliminated; Magnetic switch 5 is in off-state, and at this moment signal wire 10 is sent to other equipment with this signal, shows fluid level condition; Liquid level be can understand so at any time at a high position or low level, monitoring and control thereof helped.
What should explain at last is: above embodiment only in order to the explanation the present invention and and unrestricted technical scheme described in the invention; Therefore, although this instructions has carried out detailed explanation to the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of invention, and it all should be encompassed in the middle of the claim scope of the present invention.
