The utility model relates to a pressure and temperature measuring and controlling device for an electric pressure cooker, an electric rice cooker, a soup gruel pot and the like. Arranged in the heated liner (1) on the outer surface of the temperature sensor (2), is arranged in the heating liner (1) at the bottom of the electric heater (3) and the control of electric heater (3) of the heating power or heating accounts for the ratio of air controller (4), in which the temperature sensor (2). The signal output end and a controller (4) input terminals are electrically connected with the controller (4), and the output end of the electric heater (3) electrically connected. The temperature sensor (2) is arranged on the outer side of the heated inner liner (1) and the height of the 1 / 4 liner from the upper edge to the height of the inner liner 1 / 4 of the bottom. The utility model can not only improve the measurement accuracy, but also can realize to be heated in the liner of the food temperature and pressure temperature or pressure within the scope of the automatic detection and control, the pressure and temperature measurement and control device of electric heating cooker in a very simple way to realize stepless temperature or pressure control.
【技术实现步骤摘要】
本技术是一种用于电压力锅、电饭煲、汤粥煲等电加热炊 具的压力与温度测控装置,属于电加热炊具压力与温度测控装置的创 新技术。
技术介绍
现有电压力锅、电饭煲、汤粥煲等电加热炊具的温度测控不外 乎是釆取对被加热内胆底部中央进行测温,或者对锅盖、包括从锅盖 深入内胆方向的突出物如测温柱进行测温,或者兼而有之。其中,对于被加热内胆底部中央进行测温的结构,其存在的缺点 是难以避免发热器件(如发热盘)的热辐射干扰,并且只能局限于得 到锅内食物的底部温度的即时信息,因为对于烹调过程中会糊化或粘稠的食物,其加热过程中底部与上部的即时温度之差可达40度之多, 所以从内胆底部测温获得的信息量有限。对于从锅盖部位进行测温的结构,其存在的缺点是除了需要较 长的引线外,还不可避免产生传感器引线要经过翻盖转轴部位的长期 反复弯折破损的风险,而对于分离式锅盖类的电加热炊具,这类测温 结构要么不能使用,要么就有暴露的易被污染的对位电极触点,降低 了可靠性。如中国专利公开号为CN2870672Y中公开的一种电压力锅。此外,中国专利公开号为CN2561320Y中公开了一种新型温控电饭煲,其测温结构 ...
