Abstract
The utility model relates to a temperature sensor for embedded electric ovens, comprising a metal shell and a thermal resistor arranged in the metal shell. A pin of the thermal resistor extends out of the metal shell through a high-temperature lead-out wire. The thermal resistor is sleeved with a Teflon hose which extends to a riveting point, which makes the thermal resistor not in contact with the inner wall of the metal shell. The front end inside the metal shell is filled with a heat conducting silica gel layer, and the thermal resistor is arranged in the heat conducting silica gel layer. The metal shell is shaped through crimping, so that the thermal resistor is not easy to fall off the shell. The temperature at the front end of the metal shell is transferred to the thermal resistor by heat conducting silica gel which is high in heat transfer speed, and the metal shell can be prevented from expansion and deformation when heated to cause the thermal resistor to be extruded and damaged. The temperature sensor for embedded electric ovens has the advantages of being high in sensitivity, high in precision of temperature control, not easy to fail after long-time work in a high-temperature oven, convenient to maintain, and the like.
Description
Technical field
The utility model relates to the temperature sensor that a kind of middle high-temperature heating device is used, the temperature sensor that particularly a kind of built-in electric oven is used.
Background technology
Along with the raising day by day of people's living standard, built-in electric oven more and more becomes indispensable household electrical appliance in modern kitchen, and excellent its is subject to liking the young consumers volume curing to favor.Electric oven needs the baking temperature of food precisely to control in the process of baking and banking up with earth.But in existing market electric oven, be used for that the thermally sensitive temperature sensor of temperature control and thermometric exists that sensitivity is low, temperature-controlled precision is poor, single-point temperature control, long-term baking easily lost efficacy, be difficult for the shortcomings such as replacing, thereby easily cause the finished product baking, around color and luster is inconsistent, even there will be local burned phenomenon.
In sum, be badly in need of at present a kind of high sensitivity, temperature-controlled precision high, be difficult for after working in the baking box of high temperature for a long time losing efficacy, the temperature sensor of convenient for maintaining.
Utility model content
Technical problem to be solved in the utility model is that temperature sensor that current institute electric oven is used exists that sensitivity is low, temperature-controlled precision is poor, single-point temperature control, long-term baking easily lost efficacy, are difficult for the technological deficiencies such as replacings, redesigns the temperature sensor that a kind of high sensitivity, temperature-controlled precision are high, be difficult for inefficacy, convenient for maintaining after working in the baking box of high temperature for a long time.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The technical disadvantages that the temperature sensor of using for existing electric oven exists, redesign the temperature sensor that a kind of built-in electric oven is used, comprise metal shell and be placed in the thermistor in metal shell, the pin of thermistor extends to outside metal shell by high temperature extension line.Described thermistor cover has the contact of one deck Teflon Guan Buyu metal shell inwall; The front end of described metal shell inside is filled with thermal conductive silicon glue-line, and described thermistor is placed in heat-conducting silicone grease layer.The rear end extruding closure of metal shell fixedly high temperature extension line, specifically adopt the end of metal shell to press and shape, and fix high temperature extension line, makes thermistor be difficult for deviating from from housing.By heat transfer rate faster heat conductive silica gel the temperature of metal shell front end is delivered on thermistor, can also prevent expands with heat and contract with cold to be out of shape after metal shell is heated simultaneously causes thermistor to be extruded damage.
Connected mode between the pin of described thermistor and high temperature extension line is by copper strips, to rivet between pin and high temperature extension line.Can avoid soldering generation fusing under hot environment to cause opening circuit between pin and high temperature extension line.
In order further to improve precision, described thermistor is glass envelope thermistor.
For ease of assembly and use attractive in appearance, the structure of described metal shell is the rectangular tubular structure of one end sealing.
On the outer wall of described metal shell, riveted joint is useful on metal shell is fixed on to the shell fixed head on electric oven; Shell fixed head is mutually vertical with metal shell.
Compared with the existing technology, its beneficial effect is the utility model: owing to shell being designed to the version of one end closed tube, the installation greatly facilitating in built-in electric oven is fixed and changes; Due to the glass-encapsulated that thermistor body adopts, surface cover has one deck insulation Teflon pipe, and adopts copper strips to rivet with high temperature extension line, thereby has greatly improved thermotolerance, the reliability of sensor; Because the front end of metal shell is marked with the good heat-conducting silicone grease layer of heat conduction, sensor response speed, temperature-controlled precision have greatly been improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment mono-.
Embodiment
Embodiment mono-: as shown in Figure 1, it comprises metal shell 1 and be placed in the thermistor 2 in metal shell 1, and the pin 21 of thermistor 2 extends to outside metal shell 1 by high temperature extension line 3.Described thermistor 2 covers have one deck Teflon pipe 5 not contact with metal shell 1 inwall; The front end of described metal shell 1 inside is filled with heat-conducting silicone grease layer 4, and described thermistor 2 is placed in heat-conducting silicone grease layer 4; The rear end extruding closure of metal shell 1 fixedly high temperature extension line 3, make thermistor 2 be difficult for deviating from from metal shell 1.By heat transfer rate faster heat-conducting silicone grease layer 4 temperature of metal shell 1 front end is delivered on thermistor 2, can also prevent expands with heat and contract with cold to be out of shape after metal shell 1 is heated simultaneously causes thermistor 2 to be extruded damage.
As shown in Figure 1, the pin 21 of described thermistor 2 and the connected mode between high temperature extension line 3 are by copper strips 6, to rivet between pin 21 and high temperature extension line 3.
As shown in Figure 1, in order further to improve precision, described thermistor 2 is glass envelope thermistor.
As shown in Figure 1, for ease of assembly and use attractive in appearance, the structure of described metal shell 1 is the rectangular tubular structure of one end sealing.
