Embodiment 1

[0046] figure 1 It is a cross-sectional view of a vacuum cooking appliance according to an embodiment of the present invention; figure 2 It is a cross-sectional view of a pot cover in an embodiment of the present invention; image 3 for figure 2 The enlarged picture at a in the middle; figure 1 , figure 2 and image 3 As shown, the vacuum cooking appliance provided by the embodiment of the present invention includes a pot body 1 and a pot cover 2 covering the pot body 1. The pot body 1 is provided with an inner pot 3, and the inner pot 3 has a cavity with an upward opening. When the cover 2 is arranged on the pot body 1, the pot cover 2 and the inner container 3 are combined to form a cooking cavity. The pot body 1 or the pot cover 2 is equipped with an air extraction device, which is used to extract air from the vacuum cooking utensils at a constant air extraction rate, that is, to extract air from the cooking cavity surrounded by the combination of the pot cover 2 an...

Embodiment 2

[0059] The main structure of the vacuum cooking appliance in this embodiment is basically the same as the main structure of the vacuum cooking appliance in the first embodiment, the difference is that the pressure detection device includes a current detection unit and a pressure determination unit connected to each other, the current detection unit and the air extraction device The connection is used to detect the current signal of the air extraction device; the pressure determination unit is used to determine the pressure signal in the vacuum cooking appliance according to the current signal detected by the current detection unit. In this embodiment, according to the different load currents of the air extraction device under different air pressure states, the pressure signal of the vacuum cooking appliance at this time is judged by detecting the current of the air extraction device.

[0060] Further, the current detection unit includes a sequentially connected current detectio...

Embodiment 3

[0064] The main structure of the vacuum cooking appliance in this embodiment is basically the same as the main structure of the vacuum cooking appliance in the first embodiment, the difference is that the pressure detection device is a pressure sensor, and the pressure sensor communicates with the vacuum cooking appliance, which can directly detect the pressure inside the vacuum cooking appliance. The pressure signal of the pressure detection device makes the pressure detected by the pressure detection device more accurate.

Abstract

The invention discloses a vacuum cooking utensil and a method for determining the food material quantity in the vacuum cooking utensil. The vacuum cooking utensil comprises an air extraction device, apressure detection device and a detection module, wherein the air extraction device extracts the air from the vacuum cooking utensil at a constant air extraction speed; the pressure detection deviceis used for detecting pressure signals inside the vacuum cooking utensil; the detection module determines the time required for forming preset pressure by the vacuum cooking utensil according to the pressure signals detected by the pressure detection device, and determines the food material quantity in the vacuum cooking utensil according to the time, so that the defects of inaccurate food material quantity detection, high cost and the like of the existing cooking utensil are overcome.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a vacuum cooking appliance and a method for determining the amount of food therein. Background technique [0002] The rice cookers on the market now need to judge the amount of ingredients. The way to judge the amount of ingredients in existing rice cookers is generally through the temperature changes of the bottom and top temperature sensors; or directly at the bottom of the rice cooker. The high-precision electronic scale can judge the amount of ingredients by weighing, so as to control the cooking process according to the amount of ingredients. However, the method of detecting the amount of ingredients by using a temperature sensor, because the detected temperature lags behind the actual temperature, especially the small amount of ingredients will transfer temperature to the air and surrounding heat-absorbing materials, which will affect the accuracy of...
