Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 to Figure 9 As shown, a side-mounted solar water heater water temperature and water level sensor includes a fixed seat 1 installed on the side of the solar thermal insulation bucket 3, and a circuit board 2 is arranged in the fixed seat 1. The fixed seat 1 includes a cylindrical seat 13 with a lower bottom and The upper cover 14 is provided with a threading hole 15 at the bottom of the cylindrical seat 13, and the bottom of the cylindrical seat 13 is fixed to extend into the electrode crossbeam 4 of the heat preservation bucket; on the electrode crossbeam 4, a temperature-sensitive detector and four different lengths are hinged at equal intervals. metal rod conductive electrodes; there is a metal conductive layer on the outside of the temperature-sensitive detector, and the temperature-sensitive detector is called a temperature-sensitive cond...

Abstract

The invention discloses a side-mounted water temperature and level sensor of a solar water heater. The side-mounted water temperature and level sensor comprises a fixing seat. The fixing seat is mounted on a side surface of a solar heat-insulation bucket, a circuit board is arranged in the fixing seat, an electrode transverse beam of the heat-insulation bucket fixedly extends into the bottom of the fixing seat, a plurality of conducting electrodes made of metal rods and a temperature sensing detector are equidistantly hinged onto the electrode transverse beam, the conducting electrodes have different lengths, the upper end of each conducting electrode is connected with the circuit board by an electrode wire, and two temperature sensing wires are led out of the temperature sensing detector into the fixing seat in a communicated manner. The side-mounted water temperature and level sensor has the advantages of simple structure, stability in performance, zero faults, signal distortion and signal chaos, long service life and accuracy in display.

Description

technical field [0001] The invention belongs to the technical field of solar energy, in particular to a water temperature and level sensor for a side-mounted solar water heater. Background technique [0002] Most of the existing solar water heater water temperature and water level sensors are electrode-type sensors. This kind of electrode-type sensors often fail and have a short life. In the stainless steel tube, the gap between the electrodes is too small. With the prolongation of the use time of the solar water heater, the scale attached to several electrodes becomes thicker and thicker. The scale between the electrodes is connected together to cause a short circuit between the electrodes. The water level detection function of the sensor Ineffective, resulting in solar water heaters leaking water, not filling water, air drying and frying tubes and other failures occur from time to time. The service life of the existing solar water heater water temperature and water level ...
