Abstract
The utility model relates to a temperature control sensor of a water heater, which comprises a thermister, a metal shell and two temperature signal wires for transmitting out signals. The thermister is disposed in the metal shell and connected with the two temperature signal wires, the thermister and the temperature signal wires are poured in the metal shell by the aid of epoxy resin, one side of the metal shell is provided with a mounting support, the bottom face of the metal shell is planar or chambered, and the mounting support is provided with a mounting hole. The temperature control sensor has the advantages of reasonable structure, high mechanical strength, high heat transmission efficiency, fast response, and convenience and reliability in mounting.
Description
Technical field
The utility model relates to a kind of water heater temperature control sensor, belongs to the temperature sensor technical field.
Background technology
Temperature control sensor mainly is made of the temperature signal line of thermistor, the metal shell that plays induction and protective effect and unofficial biography signal and the pedestal of a fixation; thermistor is arranged in the metal shell and changes with the induction water temperature; export with the reflection variation of temperature by the resistance value that the temperature signal line changes thermistor, realize temperature control.But the pedestal of water heater temperature control sensor commonly used mostly adopts the copper shell to constitute, thermistor is fixed in the copper shell by epoxy resin, and the front portion that the copper shell is positioned at thermistor after flattening as pedestal, on pedestal, be provided with mounting hole again, by securing member pedestal is installed on the measured object.But in copper shell manufacturing process, needing one is the pedestal that carries out the transition to the plane from housing, and the pedestal that is connected with water heater and fixedly the copper shell at thermistor place not on same plane, thermistor is far away apart from the mounting hole centre distance on the pedestal, and the copper shell is to be that line contacts with water heater, because of fitting area is very little, heat transfer efficiency is not high, so response is unhappy rapidly.Moreover because metal shell is copper shallow shell structure, the intensity of pedestal is not high, and is flexible and fracture during installation.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, the heat transfer efficiency height, and response is fast rapidly, water heater temperature control sensor easy for installation, reliable.
The utility model is that the technical scheme that achieves the above object is: a kind of water heater temperature control sensor, the temperature signal line that comprises thermistor metal shell and unofficial biography signal, described thermistor is arranged in the metal shell and with the two temperatures signal wire and is connected, thermistor and temperature signal line use poured with epoxy resin in metal shell, it is characterized in that: the sidepiece of described metal shell has erection support, the bottom surface of metal shell is plane or cambered surface, and erection support is provided with mounting hole.
Wherein, the mounting hole site on the erection support of described metal shell is in thermistor one side, and the end face of erection support is the plane.
Described metal shell is L-shaped.
The utility model adopts a proprietary metal shell, the bottom surface of this metal shell is plane or cambered surface, and the sidepiece of metal shell is provided with erection support, rational in infrastructure, increased substantially the physical strength of metal shell, metal shell can be installed on the water heater by securing member, and can not fracture and buckling phenomenon, it is reliably convenient to install.The utility model metal shell fixedly thermistor fixed part and with the water heater fitting surface be same plane, and erection support is positioned at its sidepiece, can not only shorten the distance of thermistor apart from mounting hole centre distance, and the bottom surface of metal shell is fitted tightly on the water heater surface contact reliably with realization face, increased the contact area between metal shell and the water heater, the heat transfer efficiency height, can reach thermometric effect preferably, the thermometric response is fast rapidly, also can dwindle the volume of temperature control sensor simultaneously.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side-looking structural representation of Fig. 1.
Wherein: 1-metal shell, 11-erection support, 12-mounting hole, the outer epoxy resin of 2-, epoxy resin in the 3-, 4-thermistor, 5-temperature signal line, 6-connector.
Embodiment
See shown in Figure 1, water heater temperature control sensor of the present utility model, comprise thermistor 4, the temperature signal line 5 of metal shell 1 and unofficial biography signal, thermistor 4 is arranged in the metal shell 1 and with two temperatures signal wire 5 and is connected, thermistor 4 and temperature signal line 5 usefulness poured with epoxy resin are in metal shell 1, see shown in Figure 1, one end of thermistor 4 and temperature signal line 5 is fixed by interior epoxy resin 3, thermistor 4 is encapsulated in the interior epoxy resin 3, by outer epoxy resin 2 thermistor 4 and interior epoxy resin 3 are potted in the metal shell 1 again, the output terminal of temperature signal line 5 is connector 6 fixedly, be convenient to the connection of circuit board, thermistor 4 of the present utility model is a negative tempperature coefficient thermistor, variation by thermistor 4 induction water temperatures, and will change resistance and be passed on the control circuit board by two temperatures signal wire 5, realize temperature control.See shown in Fig. 1,2, the sidepiece of the utility model metal shell 1 has erection support 11, erection support 11 is provided with mounting hole 12, this metal shell 1 is L-shaped as shown in Figure 2, mounting hole 12 on the erection support 11 of this metal shell 1 is positioned at the sidepiece of thermistor 4, can not only effectively dwindle the volume of temperature control sensor, and shorten the distance of thermistor 4 with mounting hole 12 centre distance.Metal shell 1 of the present utility model can adopt the heat conduction alloy material to make, and the bottom surface of metal shell 1 is plane or cambered surface, can contact with water heater realization face by this bottom surface, improve heat transfer efficiency, therefore airborne contact response speed accelerates, the end face of the utility model erection support 11 is the plane, by securing member temperature control sensor is installed on the water heater reliably.
