The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
At present, water heater adopts two pipe joints to join with water inlet pipe, outlet pipe respectively, completes the water-in and water-out function.For fear of the water heater electric leakage, the user is damaged, the water pipe that generally exposes directly is not connected with inner bag, but employing insulating part, moulding commonly used, the two threaded metalwork embedding and injection moldings of joint are arrived together, wherein, a metalwork is used for being connected with inner bag, and another metalwork is used for and is connected water inlet pipe, outlet pipe connection.
As shown in Figure 1, the structure of pipe joint comprises insulating part 3 and is flush-mounted in interior two metalworks 1,2 of insulating part 3, wherein, metalwork 1 by screw thread directly and on the inner bag of water heater the screw element of water inlet or water outlet join, metalwork 2 joins by screw thread and water inlet pipe or outlet pipe.Be provided with metal temperature sensing part 4 on metalwork 1, and metal temperature sensing part 4 is drawn from insulating part 3.The part of drawing insulating part 3 in metal temperature sensing part 4 is equipped with temperature sensor.Metal temperature sensing part 4 can with metalwork 1,2 integral body be processed as one formula structure, then embedding and injection molding; Also can be fixed on metalwork 1,2 by fixture, embedding and injection molding then, fixture can be rivet, screw etc.; Can also be installed on metalwork 1,2 by modes such as welding, then embedding and injection molding.Certainly, as shown in Figure 2, also can be provided with metal temperature sensing part 4 on metalwork 2, perhaps as shown in Figure 3, be provided with temperature sensing part 4 on metalwork 1 and metalwork 2.
As shown in Figure 3, the water heater that adopts above-mentioned pipe joint is specifically described.
When pipe joint uses as admitting pipe joint, metalwork 2 and the water inlet pipe 6 of pipe joint join, metalwork 1 by screw thread directly and on water heater liner 9 screw element 8 of water inlet join, on inner bag 9, the water inlet also is provided with stay tube 5, above-mentioned parts form water inlet component, realize the water inlet of water heater.In the process of water feeding of heater, because metal has good heat-conductive characteristic, the temperature of metal temperature sensing part 4 perception accurately water inlet.When on metalwork 1 or 2, metal temperature sensing part 4 being set separately, only need to draw in metal temperature sensing part 4 the part mounting temperature sensor of insulating part 3, like this, temperature sensor can accurately detect the inflow temperature of water heater.Equally, when on metalwork 1 and metalwork 2, metal temperature sensing part 4 being set all, equal mounting temperature sensor on metal temperature sensing part 4 can be as required detects the water temperature at two metalworks 1,2 places respectively or simultaneously.
In order to detect the electric leakage situation of water heater when detecting inflow temperature, join with the detection of electrical leakage warning circuit with the metal temperature sensing part 4 on metalwork 1 and carry out detection of electrical leakage, can the metal temperature sensing part 4 on metalwork 2 temperature sensor be installed for detection of inflow temperature.Certainly, in order further to save cost, can only be provided with metal temperature sensing part 4 on metalwork 1, this metal temperature sensing part 4 had both been joined with the detection of electrical leakage warning circuit and had been carried out detection of electrical leakage, temperature sensor was installed again for detection of inflow temperature.If the water heater electric leakage, inner bag is charged, and the electric current of leakage or voltage can conduct to metal temperature sensing part 4 by metalwork 1.Just can realize leakage-current alarm by the detection of electrical leakage warning circuit (not shown) of joining with metal temperature sensing part 4, the mode that detects leakage-current alarm has multiple, the below introduces the convenient dual mode of realizing: (1) is ground connection after metal temperature sensing part 4 series resistors and LED alarm lamp or buzzer, if water heater produces electric leakage, LED alarm lamp or buzzer carry out alarm, and reminding user is processed.(2) connect bleeder circuit in metal temperature sensing part 4, bleeder circuit outputs voltage signal to the controller of control module, and controller is controlled the acousto-optic warning unit warning after receiving this signal, and reminding user is processed.
When pipe joint uses as titting water outlet, metalwork 2 and the outlet pipe 7 of pipe joint join, metalwork 1 by screw thread directly and the screw element 8 at water heater liner 9 upper water-out mouth places join, inner bag 9 upper water-out mouth places also are provided with stay tube 5, above-mentioned parts form water assembly, realize the water outlet of water heater.Delivery port and the water in inner bag of water heater liner 9 are kept apart by stay tube 5, the heat-conductive characteristic of stay tube 5 is relatively poor, but, in water heater heating process, due to volumetric expansion, the hot water at top can be excessive by outlet component, overflows outside in next process, and the metal temperature sensing part 4 on metalwork 1 and/or 2 can perceive the temperature of overflowing water this moment accurately.Equally, in the process of water outlet of water heater, the temperature that the metal temperature sensing part 4 on metalwork 1 and/or 2 also can accurately the perception water outlet.When on metalwork 1 or 2, metal temperature sensing part 4 being set separately, only need to draw in metal temperature sensing part 4 the part mounting temperature sensor of insulating part 3, like this, temperature sensor can accurately detect the leaving water temperature of water heater.Equally, when on metalwork 1 and metalwork 2, metal temperature sensing part 4 being set all, equal mounting temperature sensor on metal temperature sensing part 4 can be as required detects the water temperature at two metalworks 1,2 places respectively or simultaneously.
Also can realize the detection of electrical leakage of water heater on outlet component, specific implementation and water inlet component are similar, no longer describe in detail herein.Certainly, in order to reflect more exactly coolant-temperature gage, avoid water heater bottom on the impact of temperature sensor, generally temperature sensor is installed on the metal temperature sensing part 4 that metalwork 2 arranges.
In sum, the utility model has been simplified the mounting structure of water heater Inlet and outlet water position temperature sensor greatly, and the temperature sensor maintain and replace is simple, needn't dismantle water heater, can at the outside direct control of water heater, save manpower and materials.Simultaneously, this structure can be used for the detection of electrical leakage of water heater, has ensured user security.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
