Full-automatic numerical-control porridge and soup stewing machine

Abstract

The invention provides a porridge and soup stewing machine, which comprises a shell, a pot and a heating device. The pot and the heating device are arranged in the shell, the heating device is arranged below the pot, an electrical control system is further arranged in the shell and comprises a controller, a pot temperature sensor, a pot internal temperature sensor, an operating key and at least one heating tube arranged in the heating device, an operating key circuit board corresponds to various food cooking types, a needed cooking type is selected via the operating key circuit board, a temperature curve is set by the controller according to the selected cooking type, the heating degrees of the heating tubes are controlled according to returned temperature data, and accordingly the temperature in the pot keeps identical to the set food heating curve. By means of increasing a temperature feedback control mechanism, the porridge and soup stewing machine can really realize unattended operation, improves cooling quality, is safe and reliable, and reduces energy consumption.

Description

technical field [0001] The present invention relates to a food cooking device, more specifically, the present invention relates to a cooking device for cooking porridge or soup. Background technique [0002] A food cooking device is a device that can process food (usually by heating) to make the food more nutritious and produce a variety of flavors, such as a pot, an electric rice cooker, and the like. These food cooking devices usually include a heat source for heating food and a container with strong thermal conductivity for holding the food to be cooked, and the heating methods adopted include open flame heating, steam heating or resistance wire heating and the like. With the improvement of the level of science and technology, people's cooking requirements for various foods are also increasing, resulting in continuous technological innovations for food cooking devices. [0003] Congee and soup have been common and much-loved foods in China since ancient times. Porridge ...

Although Chinese patents CN 2621559, CN 2801007, CN 2889081, CN 201029747, CN 201079272, CN 201091517, CN 100553543, CN 201147183, CN 201492273, CN101862112 etc. all disclose various soup cookers or some porridge cookers wherein The porridge or soup machine uses a circuit control device, but most of its heating methods use an open-loop control system. During the heating process, the temperature of the cooking body and the feedback temperature of the cooked food (such as porridge or soup) are not considered, but simply It is stopped manually or by appointment, and there is no power-off protection function, which makes it difficult to control the temperature of the food or adjust the heating method according to the type of food in the process of cooking porridge or soup.

[0004] In addition, the existing porridge machine or soup machine also has other defects: (1) the way of adding water is not ideal: the existing ways of adding water mainly include manual water adding, electric pump water adding and automatic water adding with electromagnetic valve flow control

The manual water adding method cannot realize the real unattended automatic porridge or soup cooking, and the electric pump water adding method will increase the energy consumption and manufacturing cost of the porridge machine or soup making machine, while the automatic water adding controlled by the electromagnetic flow valve can solve the problem of manual and manual cooking. problem, but the safety is low. If the water flow through the electromagnetic flow valve is too small to drive the flow valve to work, the flow valve will not detect the water flow into the pot, causing the water in the pot to overflow, causing danger.

(2) Severe smell: the existing porridge or soup making machines cannot completely drain the bottom water in the pot body or the steam generator, so that the pot body will leave an aftertaste, which will affect the taste of the next pot of food

(3) Each machine part is designed independently, and there is no connection in operation, which is easy to cause misoperation. For example, the porridge or soup machine can also be opened when no water is added to the pot body, which has potential safety hazards
