Problems solved by technology

However, it is found in use that when the water in the solar water heater is too full, the air in the solar water heater is sealed inside. When the water in the solar water heater is heated, the air enclosed in the solar water heater is also heated and expands, oppressing the solar water heater. The water in the water overflows from the air outlet of the probe, causing the probe to drip continuously. This situation is especially prominent in summer, which affects the normal operation of the solar water heater to a certain extent.
In the cold season, due to the ice accumulation in the connecting pipe left on the lower cover of the probe box, the solar water heater becomes a closed container, the pressure in the solar water heater cannot be released, and water cannot be added, so that the solar water heater cannot work normally.
In addition, if the seal between the electrode and the lower cover of the probe box is not enough, water vapor will seep into the probe box from the gap between the electrode and the lower cover of the probe box. In this case for a long time, it will cause internal corrosion of the probe and the probe will give an error. The signal also affects the normal work of the solar water heater

Embodiment Construction

[0020] The embodiment shown in the accompanying drawings has a probe box 1, a pair of probe rods 3 that are electrodes and a photosensitive element 4, and the probe box 1 is formed by fitting an upper cover 1-1 and a lower cover 1-2, and the lower cover 1-2 Connected with a vertically downward straight pipe 2,

[0021] The probe 3 is vertically placed in the straight pipe 2 and its upper end is inserted into the through hole on the lower cover 1-2, and the upper part of the straight pipe 2 is filled with sealant to form a sealing layer 5 . The photosensitive element 4 is embedded in the blind hole of the lower cover 1-2 with its receiving surface facing down, and the position corresponding to the blind hole on the lower cover is a transparent or translucent layer or the whole lower cover 1-2 is made of a transparent or translucent material. become. The external natural light reaches the receiving surface of the photosensitive element through the transparent layer or transluce...

Abstract

An integrated probe of solar energy water heater consists of probe case with top and bottom covers as well as straight tube, probing bar inserting its top end to straight tube and bottom end to through hole, and photosensitive element embedding its receiving surface downwards into blind hole. It is featured as setting position corresponding to blind hole on bottom cover to be transparent, setting elbow with through hole on straight tube, making bottom end of probing bar be at point between level central line of through hole and lowest point of through hole port as well as be able to touch water surface in elbow.

Description

technical field [0001] The invention relates to a combination probe of a solar water heater, which controls the automatic water supply and water stop of the solar water heater through water level detection and light detection. Background technique [0002] With the widespread use of solar water heaters, solar water heaters that can control automatic water stop have been developed on the market. According to different control methods, it can be divided into mechanical and electronic water heaters. The mechanical solar water heater controller only solves the problem of automatic water stop, but cannot automatically add water. The electronic controller can automatically control the water supply and water stop of the solar water heater. At present, there are two types of electronic controllers on the market. One uses the water temperature and level to control the water supply and water stop of the solar water heater. This type of controller adopts Resistive or capacitive water...
