Abstract
The invention discloses an electric water heater water scale early warning device based on specific resistance measurement. The electric water heater water scale early warning device based on specific resistance measurement comprises a control panel which is fixed to the inner side of an electric water heater display panel, and further comprises a water scale testing device fixed to the inner wall of an electric water heater water storage chamber. The water scale testing device comprises a temperature sensor, a specific resistance measurement unit and measurement probes, wherein the measurement probes are arranged oppositely. The control panel is electrically connected with the water scale testing device. According to the electric water heater water scale early warning device based on specific resistance measurement, the specific resistance of a water-water scale composite medium is measured through the oppositely arranged measurement probes, and the temperature sensor is used for carrying out temperature compensation correction. The specific resistance is changed when water scale is increased. When the specific resistance of the composite medium exceeds a preset warning value, the control panel displays the specific information through the display panel and controls a warning light to flash to remind a user to pay attention to scale removal. The electric water heater water scale early warning device based on specific resistance measurement is simple in structure, convenient to use and easy to popularize.
Description
Technical field
The present invention relates to a kind of water heater monitoring device, be specially a kind of electric heater incrustation scale prior-warning device based on resistivity measurement, belong to automatic monitoring technical field.
Background technology
Electric heater Long-Time Service all can produce certain incrustation scale, and storage-type electric water heater intermittent-heating repeatedly in insulating process, the heat time is long, more easily produces incrustation scale.The thermal conductivity of incrustation scale is very poor, incrustation scale is attached on the heating rod of electric heater, the efficiency of heating surface can be affected greatly, power consumption is increased, also the service life of heating rod is shortened, incrustation scale easily makes inner container of electric water heater be out of shape under the long-term alternating action of cold water, hot water, and the smooth and inner bag of heating is out of shape all can damage electric heater, even causes danger.Therefore the incrustation scale in electric heater is needed regularly to remove, but user will check that in electric heater, scale build-up situation is inconvenient, therefore a kind of instrument understanding incrustation scale situation is easily needed, to meet the needs that ordinary people takes measures to clear up electric heater incrustation scale in time.
Summary of the invention
The object of the present invention is to provide a kind of electric heater incrustation scale prior-warning device based on resistivity measurement being convenient to understand electric heater incrustation scale accumulation, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: a kind of electric heater incrustation scale prior-warning device based on resistivity measurement, comprise control panel, described control panel is fixed on the inner side of electric heater display floater, also comprise the incrustation scale testing arrangement being fixed on electric heater reservoir chamber inwall, described incrustation scale testing arrangement comprises temperature sensor, resistivity measurement unit and measuring probe, and described measuring probe is oppositely arranged, and described control panel is electrically connected incrustation scale testing arrangement.
Preferably, described display floater is provided with warning lamp, and warning lamp and control panel are electrically connected.
Preferably, described incrustation scale testing arrangement is connected with control panel wireless telecommunications by bluetooth, ZigBee or wireless mode.
Compared with prior art, the invention has the beneficial effects as follows: the resistivity being measured water-incrustation scale complex media by the measuring probe be oppositely arranged, carry out temperature-compensating rectification by temperature sensor, incrustation scale increase the change that can cause resistivity, when the resistivity of complex media exceedes default warning value, control panel shows specifying information by display floater, and controlling warning lamp flicker, prompting user notes scale removal, and its structure is simple, easy to use, be easy to universal.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, a kind of electric heater incrustation scale prior-warning device based on resistivity measurement of the present invention, comprise control panel 1, described control panel 1 is fixed on the inner side of electric heater display floater 2, also comprise the incrustation scale testing arrangement 4 being fixed on electric heater reservoir chamber 3 inwall, described incrustation scale testing arrangement 4 comprises temperature sensor 41, resistivity measurement unit 42 and measuring probe, and described measuring probe is oppositely arranged, and described control panel 1 is electrically connected incrustation scale testing arrangement 4.
Described display floater 2 is provided with warning lamp 5, and warning lamp 5 and control panel 1 are electrically connected, and when the resistivity measured exceedes default warning value, warning lamp 5 glimmers to play indicative function; Described incrustation scale testing arrangement 4 is connected with control panel 1 wireless telecommunications preferably by bluetooth, ZigBee or wireless mode, can break away from the restriction of wired connection.
When Non-scale, what measuring probe measured is resistivity of water, after incrustation scale accumulates gradually, measuring probe is also attached with incrustation scale, what measuring probe measured is the resistivity of water-incrustation scale complex media, along with increasing of incrustation scale, resistivity increases gradually, and when the resistivity of complex media exceedes default warning value, control panel 1 shows specifying information by display floater 2, and control warning lamp 5 and glimmer, prompting user notes scale removal.During cleaning electric heater incrustation scale, the incrustation scale on measuring probe is also washed in the lump, make measuring probe enter next testing process.In addition, also transfer by control panel 1 at ordinary times and check Resistivity testing result.The present invention can guarantee that electric heater normally runs, and is beneficial to electric heater energy-conservation, and structure is simple, easy to use, is easy to promote.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, it still can be modified to the technical scheme described in previous embodiment, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, those skilled in the art do not pay any modification, amendment, improvement etc. that creative work is done, and all should be included within protection scope of the present invention.
