Abstract
The utility model relates to a temperature sensor for an intelligent electric rice cooker. The temperature sensor comprises a metal casing and a thermistor arranged in the metal casing, wherein a pin of the thermistor extends outside the metal casing through a high temperature leading-out wire, a heat conduction silicone grease layer and a solid heat conduction epoxy resin layer are sequentially filled from a front end of an inner portion of the metal casing to an opening portion of the metal casing, the thermistor is arranged in the heat conduction epoxy resin layer and is at the connection side of the heat conduction silicone grease layer and the heat conduction epoxy resin layer, and the heat conduction epoxy resin layer is further internally provided with a resettable temperature limiter. The temperature sensor is advantaged in that mounting, fixing and replacement are convenient; reliability and heat resistance of a sensor are improved; waterproofness of the sensor is improved; use safety and reliability of the intelligent electric rice cooker are improved.
Description
Technical field
The utility model relates to the temperature sensor that a kind of cooking equipment is used, the temperature sensor that particularly a kind of intelligent electric cooker is used.
Background technology
Traditional electric cooker adopts the mode of mechanical type or constant power to heat mostly in the market, and energy utilization rate is low, and function singleness is difficult to meet the growing life requirement of people.So diverse in function is safe and reliable, the intelligent electric cooker of fashion attractive in appearance more and more becomes people and pursues the indispensable household electrical appliance that high-quality is lived.And temperature is to control a very crucial physical quantity of intelligent electric cooker culinary art, intelligent electric cooker can carry out monitoring temperature, what judgement may occur adds thermal defect, and then can find in time, process, the generation of pre-antiseized pot phenomenon, thereby and can ensure according to prior Temperature Setting operation the quality of culinary art.Must be by the advanced trip temperature collection of thermistor temperature sensor combination with the MCU and realize this process, then carry out digital temperature conversion and export being just achieved.And traditional electric cooker temperature-control structure is mechanical, its shortcoming is that volume is not easy to greatly install and changes, and unsealing water proofing property is poor, and temperature control poor sensitivity after long-time use, reaction velocity are slow, and temperature control easily lost efficacy and produces the phenomenon of being burned.
In sum, be badly in need of at present a kind of high sensitivity, temperature-controlled precision is high, waterproof sealing is high, the temperature sensor of convenient for maintaining.
Utility model content
Technical problem to be solved in the utility model is the shortcoming in order to overcome traditional electrical rice cooker, realize the advantage of intelligent electric cooker, the utility model object is to provide that small and exquisite firm, the simple installation of a kind of structure, interchangeability are good, highly sensitive, fast response time, temperature-controlled precision are high, good heat resistance, good waterproof performance, the highly reliable temperature sensor of high precision for safe and reliable intelligent electric cooker.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The technical disadvantages that the temperature sensor using for existing electric cooker exists, redesign the temperature sensor that a kind of intelligent electric cooker 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.The front end of described metal shell inside is filled with heat-conducting silicone grease layer and solid-state heat-conduction epoxy resin layer successively to the opening part of metal shell, and described thermistor is arranged in heat-conduction epoxy resin layer and is positioned at the side that heat-conducting silicone grease layer is connected with heat-conduction epoxy resin layer; In described heat-conduction epoxy resin layer, be also provided with reducible temperature limiter.Metal shell can pass to temperature sensor heat fast by thermal conductive silicon glue-line, and heat-conduction epoxy resin layer has increased waterproof sealing when playing auxiliary heat conduction.Described temperature limiter can effectively prevent electric cooker overheated problem of burning in cooking process.
For more effective carry out heat transmit, the front end of described thermistor and thermal conductive silicon glue-line fit.
For convenient installation and attractive in appearance, described metal shell is the tubulose of one end sealing, and the xsect of metal shell is " T " font, is respectively arranged with and is convenient to fixedly mount the annular projection of metal shell and annular groove on the sidewall of metal shell.
On the sidewall of described metal shell and be positioned at opening part and be provided with the breach of being convenient to high temperature extension line and carrying out 90 ° of bendings.
Compared with the existing technology, its beneficial effect is the utility model: the installation greatly facilitating on intelligent electric cooker is fixed and changes; Reliability, the thermotolerance of sensor are greatly improved; Because outer casing bottom is marked with the good heat-conducting silicone grease of heat conduction, and then solidify with epoxy sealing, greatly improved sensor water-proof, response speed is less than 7 seconds; Because wall place is in the enclosure provided with reducible temperature limiter, in the time of excess Temperature, temperature limiter can disconnect heating power supply, has greatly improved intelligent electric cooker safety in utilization, reliability.

Embodiment
Embodiment mono-: as shown in Figure 1, 2, 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.The front end of described metal shell inside is filled with heat-conducting silicone grease layer and solid-state heat-conduction epoxy resin layer successively to the opening part of metal shell, and described thermistor is arranged in heat-conduction epoxy resin layer and is positioned at the side that heat-conducting silicone grease layer is connected with heat-conduction epoxy resin layer; In described heat-conduction epoxy resin layer, be also provided with reducible temperature limiter.Metal shell can pass to temperature sensor heat fast by heat-conducting silicone grease layer, and heat-conduction epoxy resin layer has increased waterproof sealing when playing auxiliary heat conduction.Described temperature limiter can effectively prevent electric cooker overheated problem of burning in cooking process.
As shown in Figure 2, for more effective carry out heat transmit, the front end of described thermistor and heat-conducting silicone grease layer fit.
As shown in Figure 1, for convenient installation and attractive in appearance, described metal shell is the tubulose of one end sealing, and the xsect of metal shell is " T " font, is respectively arranged with and is convenient to fixedly mount the annular projection of metal shell and annular groove on the sidewall of metal shell.
As shown in Figure 1, on the sidewall of described metal shell and be positioned at opening part and be provided with the breach of being convenient to high temperature extension line and carrying out 90 ° of bendings.
