Description

automatic water supply rice cooker

technical field

The utility model relates to an intelligent kitchen appliance product, specifically a rice cooker with automatic water supply and electric power utilizing mature single-chip microcomputer technology, automatic control technology and sensor technology.

Background technique

The rice cooker is one of the indispensable kitchen appliances in people's homes. Now the intelligence of the rice cooker has brought great convenience to people's cooking. Today's smart rice cookers can not only cook rice, porridge, and soup, but also have a timer reservation control function. Some rice cookers can be reserved for 12 hours, and some can be reserved for 24 hours. Many families utilize the reservation function of electric rice cooker to cook breakfast and dinner. Many families are used to eating porridge in the morning, so put rice and water into the rice cooker at night, and use the timing reservation control function, and you can eat hot porridge after getting up in the morning. There are also many families of office workers who like to make an appointment to cook before going to work in the morning, and the rice will be cooked when they come back in the evening. But this method is only suitable for use in winter. After the ambient temperature rises, if the rice and water are left in the rice cooker for a night or a day, it is easy to deteriorate; in addition, the rice that has been soaked for a long time is made The taste of the rice is not good.

Contents of the invention

In order to solve such problems, the purpose of this utility model is to provide a kind of automatic water supply rice cooker. The rice cooker retains the functions of the traditional smart rice cooker, and adds an automatic water supply control function on the basis of the traditional smart rice cooker. It is easy to use and avoids the rice being soaked in water for a long time or the taste becomes bad. The problem.

The purpose of this utility model is achieved through the following technical solutions:

An automatic water supply electric rice cooker, comprising a pot body, is characterized in that: a single chip microcomputer and a pressure sensor are arranged in the pot body, and an automatic water supply switch, a keyboard, a boiling switch, a heat preservation switch and an LED display are arranged on the pot body; The switch, pressure sensor, keyboard, boiling switch, heat preservation switch and LED display are all connected to the single-chip microcomputer; There is a water inlet on it.

The utility model is provided with the water volume selection button and the reservation timing selection button on the keyboard. The automatic water supply switch is an electromagnetic switch, which will automatically turn on the water supply switch to release water after the time is up. The pressure sensor detects the pressure generated by the inner tank, sends the detected data to the single-chip microcomputer for processing, and compares it with the set water quantity parameters. When the set parameter value is reached, the single-chip microcomputer sends a control signal to the automatic water supply switch, thereby Turn off the electromagnetic switch, and then the rice cooker starts the cooking function.

In order to prevent the high temperature of the inner tank of the electric rice cooker from damaging the pressure sensor, a heat insulation layer is provided between the pressure sensor and the inner tank of the electric rice cooker.

The water volume parameters set in the single chip microcomputer can be obtained through trial and error before the product is produced, and the set parameters correspond to different water volumes on the button selection switch.

In the utility model, the single-chip microcomputer is the control core of the circuit. The keyboard includes a cooking function selection button, an appointment timing time selection button, a water volume selection button, and a start button. LED display mainly includes power indicator light, cooking indicator light, heat preservation indicator light, water quantity indicator light, and timing display. 

The utility model utilizes mature single-chip microcomputer technology, automatic control technology, sensor technology, chips and devices used in the circuit, and has relatively low price and low cost, and realizes productization with high economic value and broad application prospects. the

The utility model is suitable for making porridge or rice by adopting the rice without washing. Just put the rice into the rice cooker, press the preset control and select the water volume, and when the preset time comes, the rice cooker will automatically open the water inlet, put in the appropriate amount of water, and start cooking porridge or rice.

Detailed ways

A kind of automatic water supply rice cooker described in the utility model, Fig. 1 is the control circuit schematic diagram of the utility model. The electric rice cooker includes a pot body, in which a single chip microcomputer 1 and a pressure sensor 3 are arranged, and an automatic water supply switch 2, a keyboard 4, a boiling switch 5, a heat preservation switch 6 and an LED display 7 are arranged on the surface of the pot body; an automatic water supply switch 2 , pressure sensor 3, keyboard 4, cooking switch 5, heat preservation switch 6 and LED display 7 are all connected with single-chip microcomputer 1; 6 and the LED display 7 are controlled; the pot body is provided with a water inlet.

The water inlet is arranged on the top of the electric rice cooker, and is connected with the water tap (similar to the water inlet of the washing machine) as the inlet of the water. The keyboard 4 is provided with a water volume selection button and an appointment timing selection button. The automatic water supply switch 2 is an electromagnetic switch, and after the timing time arrives, the water supply switch 2 is automatically opened to discharge water. The pressure sensor 3 detects the pressure generated by the inner tank, sends the detected data to the single-chip microcomputer 1 for processing, compares it with the water quantity parameter set in the single-chip microcomputer 1, and when the set parameter value is reached, the single-chip microcomputer 1 sends a control signal Give the automatic water supply switch 2 to close the electromagnetic switch, and then the electric rice cooker starts the cooking function.

In order to prevent the pressure sensor 3 from being damaged by the high temperature of the inner container of the electric rice cooker, a heat insulation layer is provided between the pressure sensor 3 and the inner container of the electric rice cooker.

The single-chip microcomputer is the core of the control. The pressure sensor is used to detect the pressure generated by the inner tank of the rice cooker, and the detected data is sent to the single-chip microcomputer. The single-chip microcomputer compares the data with the preset parameters to control the amount of water intake.

When in use, put the rice without washing into the electric rice cooker, and then select the amount of water and the preset timing time through the keyboard 4 . In this way, after the time is up, the appropriate amount of water will be automatically put in, and the cooking can be done automatically.
