At present, existing Domestic electric kettle temperature-sensitive device major part is to adopt the bimetal leaf induction installation, the heated condition of insulating pot is judged and controlled to the temperature of induction heater and steam, and this induction installation is simple and reliable, is widely used in the insulating pot of common heating type, but the function singleness that this device is realized, people generally pursue product diversification, personalization along with growth in the living standard now, product needed expansion more function increases more for a long time color still; So, proposed to use the design of the responsive temperature measuring equipment of electronics, cooperate electronic control circuit, realize more function.
In addition, as Chinese patent 200520059247.7, a kind of electronics water thermometric temperature sensor of stewing that is used for, employed temperature sensor is arranged on the heat-generating disc, and the compressing tablet that uses is sheet metal, because heat-generating disc is a metalwork, that just exists thermal inertia in the heating process, the encapsulation of NTC thermistor also is to adopt metalwork, and the thermal inertia on the heat-generating disc is directly transferred on the thermistor, has influence on the temperature survey accuracy.
According to the above, need a kind of fluid temperature sniffer of redesign, to improve the performance of existing measurement mechanism, improve measuring accuracy.
Summary of the invention
The purpose of this utility model is to solve the problem that above-mentioned prior art exists, a kind of insulating pot that temperature sensor is contained in the band immersion temperature detection device of kettle body side wall is provided, temperature sensor is separated with heat-generating disc, temperature sensor directly is immersed in the liquid, the temperature of sensing is the true temperature of liquid, not influenced by the thermal inertia of peripheral devices.
The technical scheme that its technical problem that solves the utility model adopts is:
The insulating pot of this band immersion temperature detection device comprises the kettle body, is provided with heat-generating disc in the kettle body, on the kettle body temperature sensor is installed, and the inner unsettled of this temperature sensor stretched in the kettle body, and is positioned at the top of heat-generating disc.Like this, temperature sensor separates with heat-generating disc, and temperature sensor directly is immersed in the liquid, and the temperature of sensing is the true temperature of liquid, not influenced by the thermal inertia of peripheral devices.The error that experiment showed, detecting temperature is in ± 1 ℃; The control of this unit temp is accurate, of many uses, has overcome weak point of the prior art.
Further, the sidewall of kettle body has installing hole, and described temperature sensor is located in this installing hole, and is provided with a yard frame outside it, and this yard frame is fixed temperature sensor by securing member; Be lined with sealing ring between temperature sensor and the installing hole.Temperature sensor is a boss structure, is provided with to be convenient to yard frame with its step surface that is fixed.Like this, temperature sensor can be contained on the kettle body securely.
Sealing ring is designed to projective table type, and sealing ring is inner to be cooperated with the installing hole inner wall sealing of kettle body, and the sidewall of sealing ring raised head face and kettle body is sealed and matched, and forms the two seals face.Like this, good sealing effect.
Temperature sensor is installed on the junction of handle and kettle body, is positioned at handle.Like this, temperature sensor can be hidden in the handle, make the insulating pot profile more attractive in appearance.
Temperature sensor and heat-generating disc be arranged in parallel.Temperature sensor and heat-generating disc are apart between the 10-15mm.So not only stow away from heat disturbs, and measures accurately.
The beneficial effects of the utility model mainly show: temperature sensor directly is immersed in the liquid, and temperature sensor is fixed on the kettle body side wall, thermal source away from the heat-generating disc heater members disturbs, do not produce heat transmission with heater members, be not subjected to the influence of sensor peripheral devices, thereby reduce the error measured to greatest extent, improved the precision of measuring, improved the security of products energy simultaneously.
