Abstract

一种带声音提示的电饭煲涉及日常生活用品技术领域,带声音提示的电饭煲包括:电饭煲体1,电饭煲体1上装有控制电路器件。其优点是:当用电饭煲煮饭时,没有按下开关,就会发出声音提示按下开关,当按下开关后,声音就停止,避免了没有按下开关,等到吃饭时,饭没有熟的现象,饭熟后,发出声音提示,可拔掉插头。

Description

带声音提示的电饭煲
技术领域
本实用新型涉及日常生活用品技术领域,具体地说是一种带声音提示的电饭煲。
背景技术
现在的电饭煲都是按上电钮后煮饭,饭熟后跳开关保温,什么时间饭熟一点不知道,影响下面操作过程。
发明内容
本实用新型的目的是设计一种电饭煲的饭做好后,除自动保温外还可以发出报警声音,提示饭做好了的带声音提示的电饭煲.
本实用新型带声音提示的电饭煲包括:电饭煲体1,电饭煲体1上装有控制电路器件。
控制电路器件包括:串联的指示灯L2、电阻R2和电阻R3并联,电阻R5、二极管D和并联的蜂鸣器SP、电容C并联后串联,并且和R3并联,同时和开关S1并联,指示灯L1、电阻R1、串联电路和R4并联后和上述电路相连。
带声音提示的电饭煲是这样实现的:接通磁控开关S1,A、B间短路,发热盘R4加热煮饭,煮饭指示灯L1亮,饭熟后,磁控开关S1断开,辅助加热电阻R3和发热盘R4串联加热进行保温。此时,煮饭指示灯L1两端电压低,不能亮,而保温指示灯L2两端的电压升高点亮;蜂呜器SP经降压电阻R5、整流二极管D、滤波电容C发出声音。
本实用新型带声音提示的电饭煲优点:当用电饭煲煮饭时,没有按下开关,就会发出声音提示按下开关,当按下开关后,声音就停止,避免了没有按下开关,等到吃饭时,饭没有熟的现象。饭熟后,发出声音提示,可拔掉插头。
附图说明
图1为带声音提示的电饭煲结构示意图。
图2为电路原理图。
具体实施方式
根据图1、图2所示,电饭煲体1,电饭煲体1上装有控制电路器件。控制电路器件包括:串联的指示灯L2、电阻R2和电阻R3并联,电阻R5、二极管D和并联的蜂鸣器SP、电容C并联后串联,并且和R3并联,同时和开关S1并联。指示灯L1、电阻R1、串联电路和R4并联后和上述电路相连。

Claims (2)

1、一种带声音提示的电饭煲包括:电饭煲体(1),其特征在于:电饭煲体(1)上装有控制电路器件。
2、根据权利要求1所述的带声音提示的电饭煲,其特征在于:控制电路器件包括:串联的指示灯L2、电阻R2和电阻R3并联,电阻R5、二极管D和并联的蜂鸣器SP、电容C并联后串联,并且和R3并联,同时和开关S1并联,指示灯L1、电阻R1、串联电路和R4并联后和上述电路相连。
