Abstract
The utility model relates to a water level sensor used for a solar power water heater. The utility model comprises a magnetic-transmitting bypass pipe which can be communicated with an inner cavity of a water tank of a solar power water heater, and can be arranged vertically. A magnetic floater is arranged in the inner cavity of the bypass pipe. Magnetic-sensing parts which are arranged low-and-high are arranged on a circuit vertically arranged neighboring the bypass, and a power connection is formed between the outer-connected signals and each magnetic-sensing part via the circuit respectively. With the adoption of the water level sensor used for a solar power water heater, as the permanent magnet, magnetic-sensing part, temperature sensor, circuit and outer-connected signal wire in the magnetic floater do not directly touch water, and then the polarization and rust can be avoided with long service life, and the failure-rate is low. The running is reliable with high sensitivity, and without electric shock and the usage is safe.
Description
Technical field
The utility model relates to a kind of water level sensor for solar water heater.
Background technology
Solar water heater, because both energy savings helps environmental protection again, thereby no matter is the city, still the rural area adopts the user of solar water heater hot water supply more and more.At present, the water level detecting of solar water heater is to adopt the soaking type probe electrode always.Adopt this mode to carry out water level detecting, its drawback is: 1, the very easily polarized or corrosion of probe electrode, and serviceable life is short; 2, because probe electrode directly contacts with water, exist potential Danger Electric shock risk.
Summary of the invention
The purpose of this utility model provides the water level sensor for solar water heater of a kind of long service life and safety.
In order to realize above-mentioned purpose, this water level sensor for solar water heater, comprise can be communicated with the reserve tank inner chamber of solar water heater, and vertical placement can magnetic conduction by-pass pipe, the magnetic float is housed in the inner chamber of by-pass pipe, the magnetosensitive device that distributes by height is housed on the circuit board near the vertical placement of by-pass pipe, and each magnetosensitive device all is electrically connected with outer signal line formation by circuit board respectively.
Above-mentioned magnetic float comprises the shell of moulding of a sealing, is connected with permanent magnet moulding in the shell inner chamber of this sealing, and this permanent magnet can be to be embedded in to mould on the shell.
Above-mentioned magnetosensitive device is a tongue tube, and its quantity is 3-5, also can select other magnetosensitive device for use.
As improvement to this water level sensor for solar water heater, on by-pass pipe, be set with the Pipe joint assembly of good heat conductivity, temperature sensor is housed on the Pipe joint assembly, temperature sensor is electrically connected with outer signal line formation by circuit board.
Further improvement as to this water level sensor for solar water heater also comprises the plastic casing that by-pass pipe, circuit board, Pipe joint assembly and temperature sensor is placed its inner chamber, is set with upper end cap and lower endcaps on the plastic casing.
During installation, water level sensor for solar water heater described in the utility model is contained on the water inlet pipe of reserve tank, constitute a linker with reserve tank, the outer signal line of magnetosensitive device and temperature sensor is connected on the corresponding input end of the controller that is complementary with this water level sensor for solar water heater.
The principle of work of water level sensor for solar water heater described in the utility model is: 1, water level detecting, because by-pass pipe and reserve tank constitute linker, water level in the by-pass pipe is exactly the water level in the reserve tank, the magnetic float fluctuates accordingly with the variation of the water level of by-pass pipe, when the water level position that floats to the most close that magnetosensitive device of magnetic float, the state of this magnetosensitive device becomes closure state by off-state under the effect in magnetic float magnetic field, so this non-electrical signal of water level is transformed into switched electrical signal, this switched electrical signal is input to controller and carries out data processing, again by controller control to the reserve tank water inlet or stop into water; 2, temperature detection, because temperature sensor is contained on the Pipe joint assembly of good heat conductivity, Pipe joint assembly contacts with the water of linker again, therefore represent the temperature of hot water temperature's Pipe joint assembly in the reserve tank to be transformed to electric signal, be input to controller through the outer signal line and show and handle by temperature sensor.
By above narration as can be known, water level sensor for solar water heater described in the utility model, because permanent magnet, magnetosensitive device, temperature sensor, circuit board and outer signal line in the magnetic float directly do not contact with water, its beneficial effect is: 1, do not have polarization and corrosion phenomena, long service life; 2, failure rate is low, and reliable operation is highly sensitive; 3, there is not the danger of electric shock, safe in utilization.
