Description
Technical field
The present invention relates to water pump system, relate in particular to a kind of water pump with noncontacting proximity sensor.
Background technique
The Along with people's growth in the living standard; The full-automatic regularly circulating water pump of constant temperature finds broad application; Temperature measuring equipment in the existing heat pump is temperature transducer to be directly installed on the water pipe surface perhaps directly stretch into water pump internal measurement water temperature, and this temperature transducer is called the contact temperature-measuring device with the temperature measuring equipment that measured article directly contacts, and the drawback of this contact temperature-measuring device is that temperature transducer damages easily; Be not easy to maintain and replace, cost height and not attractive in appearance; The circuit that exposes of temperature measuring equipment connects more complicated simultaneously, causes the confusion of temperature transducer when collecting signal and feedback signal easily, causes the error of actual measurement temperature.
Summary of the invention
The present invention is directed to deficiency and defective that existing technology exists, provide a kind of not fragile, to detect water temperature convenient accurately with the water pump of noncontacting proximity sensor.
For this reason; The present invention takes following technological scheme: a kind of water pump that has noncontacting proximity sensor; Comprise the pump housing, drive the motor of the pump housing and place the controller on the motor, it is characterized in that: said controller exposes to motor towards the end extension of the pump housing, and this exposed junction is provided with temperature measuring hole; Installing infrared temperature sensor and the temperature signal regulation amplification circuit that is electrically connected on this sensor on the described controller; It is other also facing to the pump housing that described infrared temperature sensor is positioned at temperature measuring hole.
Infrared temperature sensor is arranged on the controller, does not take up space, and does not contact with the pump housing, and is not fragile, owing to only utilize a bit of extension of controller to expose portion, sensor is provided with hidden attractive in appearance, needn't the external application lead.Infrared temperature sensor detects the temperature of the pump housing, and the temperature conversion program through the controller inner setting becomes the water temperature in the pump with the temperature conversion of this housing.Because contactless infrared temperature sensor is set directly on the controller, the contact of discord pump housing shell wall makes temperature transducer not fragile, and it is accurately convenient to measure temperature.The temperature signal regulation amplification circuit is used for correcting because variation of ambient temperature and pump housing heating causing contactless temperature-measuring are popped one's head in to thermometric error.
As preferably, described controller comprises control panel and pedestal, is installed on the working surface of motor lighting outlet, and described temperature measuring hole is located on the pedestal.
As preferably, described controller has arc notch towards an end of the pump housing, and the shape of said arc notch and the curved profile of the pump housing are adaptive.When the user adjusted the fit angle of water pump and motor for adapting to on-the-spot installing space, this arc notch can allow the arc shell of water pump to embed, and prevented to interfere and do not influence exposed junction corresponding to the pump housing.
As preferably, described temperature measuring hole is located at the below of the other corner of arc notch, and described infrared temperature sensor is internal or external at temperature measuring hole.Infrared temperature sensor is located at corner, and is not only hidden but also can aim at the pump housing, receives the protection of pedestal simultaneously, not fragile and displacement.Infrared temperature sensor can be located in the temperature measuring hole and also can be located at outside the temperature measuring hole, can not be blocked facing to the pump housing as long as guarantee infrared temperature sensor.Because the other turning of arc notch is over against the pump housing, temperature measuring hole is located at corner can be so that infrared sensor be no matter be built-in or being placed on temperature measuring hole can face toward the pump housing.
As preferably, be coated with Sealing on the described infrared temperature sensor.Sealing can be casting glue or thin slice etc., coats infrared temperature sensor with Sealing and can protect temperature probe.
As preferably, have the regularly arranged unthreaded hole of annular on the described control panel, described unthreaded hole below installing light emitting diode, described light emitting diode is contained on the substrate; On the described control panel adjusting knob is housed, described adjusting knob below is provided with a rotating coder, and described rotating coder and temperature signal regulation amplification circuit also are connected on the total control circuit.Change and regulate the circuit connecting relation of rotating coder through turning adjusting knob, realize set time or temperature, swift and convenient to operate, simple; Light so that unthreaded hole appears is indicated as gear and corresponding corresponding time value or temperature value, and is eye-catching clear, effectively avoids the setting value mistake; Because light emitting diode is low in energy consumption, it is little to take up room, substrate can bearer circuit with the work of control light emitting diode, also can become the supporting base of light emitting diode, make little and thin that this controller can do, reduce volume; Can change the relevant parameter of total control circuit through adjusting knob, reach the adjusting purpose.Described total control circuit is conventional functional circuit, does not launch to describe.
As preferably, described pedestal is provided with mounting hole and needle-like pin, has on the working surface of described motor lighting outlet and the corresponding jack of needle-like pin number and position.Mounting hole is used for fixing the device seat, and the needle-like pin is used for the transmitting control data signal after inserting jack, better utilization the carrying support function of pedestal.
As preferably; Described adjusting knob is step-like cylindrical body; The cylindrical body bottom has inner cavity, has annular groove on the step surface, and described rotating coder is provided with the plush copper that can insert inner cavity; Described knob hole periphery is provided with annular boss, and described annular groove is nested with on described annular boss.The shape of adjusting knob can the easy-to-operat person operation, the effect of annular boss is the location adjusting knob.
As preferably; Described infrared temperature sensor is for surveying the temperature transducer of pump body temperature and ambient temperature respectively; The temperature signal regulation amplification circuit comprises the ambient temperature signal circuit and the water temperature signal circuit of parallel connection, and the output terminal of described ambient temperature signal circuit and water temperature signal circuit is connected in a signal correcting circuit.Because infrared temperature sensor does not directly contact with the pump housing; The temperature variation that makes the heating of variation of ambient temperature and pump housing shell wall cause all can cause error to thermometry; Infrared temperature sensor is connected with total control circuit through the temperature signal regulation amplification circuit; The temperature signal regulation amplification circuit can be adjusted the temperature signal that infrared temperature sensor detects; The water temperature that the variation of rectification external temperature and pump housing heating cause changes to infrared temperature sensor measures the error that temperature is brought, and makes thermometry more accurate.
Beneficial effect of the present invention: the present invention is through changing the contact temperature-measuring device in the conventional heat pump system into noncontacting proximity sensor; Infrared temperature sensor does not contact with the pump housing; The installation infrared temperature sensor of recessive type, attractive in appearance reliably, not fragile, the accuracy that records water temperature is than higher.
