detailed description

Below, with reference to accompanying drawing and embodiment the utility model is described in detail:

As shown in Figures 1 to 3, a cooking utensil with a rice-water ratio detection function includes a body 2 with an inner tank 1 and a cover 3 fastened on the upper side of the body 2, and a detection inner tank is arranged in the body 2 1 and the pressure sensor 4 of the quality of the rice-water mixture inside it, a detector 5 is arranged on the cover body 3, and the detector 5 measures the distance between the water surface in the inner tank 1 and the detector 5, and the pressure sensor 4 and The detector 5 is connected to a control device 6 for measuring the ratio of rice to water and prompting the user how to further cook.

There are multiple pressure sensors 4 , and the pressure sensors 4 are arranged on the lower side of the bottom of the inner tank 1 or the lower side of the edge extending outward from the opening of the inner tank 1 .

The detector 5 is an ultrasonic sensor or a light wave sensor.

The detector 5 is arranged at the center of the lower side of the cover body 3 .

A cooking method, comprising the steps of:

iPut rice and water into the inner tank, close the lid;

ii The detector 5 measures the distance H ₁ between the water surface in the inner tank and the detector 5;

iii pressure sensor 4 measures the total mass M _x of inner bag and rice water mixture;

The iv control device 6 receives the information of the detector 5 and the pressure sensor 4 and calculates the comparison result of the ratio of rice to water;

vPrompts according to the comparison results. When cooking is suitable, it prompts that the next step of cooking can be performed. When the water is too much, it prompts to reduce the water. When the water is too small, it prompts to increase the water.

Include the following calculation steps in the described step iv:

a preset the mass M of the rice-water mixture suitable for cooking corresponding to the distance H1 between the water surface in the inner tank ₁ and the detector 5, and M is a range interval value;

b Calculate the total mass M _x and M of the inner container and the rice-water mixture measured by the pressure sensor 4, and output the calculation result;

c Judging the calculation results in step b, when M _x is equal to or included in M, it is suitable for cooking, when M _x is less than M, it means too much water, and when M _x is greater than M, it means too little water.

In the described step a, the method of presetting the rice-water mixture quality M suitable for cooking corresponding to the distance H1 between the inner water surface _of the liner and the detector 5 is:

The first step is to determine the volume V of the rice-water mixture. According to the distance H ₁ between the water surface and the detector 5 and the distance between the bottom H of the inner tank 1 and the detector 5, the distance from the water surface to the bottom of the inner tank 1 is H ₂ =HH ₁ , The volume V of the rice-water mixture is obtained according to the fixed shape of the inner container 1 .

The second step is to determine the average density P of the rice-water mixture. According to the density of water P ₁ =m ₁ /v ₁ and the density of rice P ₂ =m ₂ /v ₂ , and the appropriate ratio N of rice-water mixture, determine the rice water The density of the mixture is P=m1+m2/(v1+v2);

The third step is to determine the mass M=V*P of the rice-water mixture suitable for cooking.

The rice-water mixture ratio N in the second step is 1:1.2, the density of the water is 1g/ml, and the density of the rice is about 1.5g/ml.

The cover body 3 is equipped with a water level detector, that is, it only needs to detect the height of the water surface and the average density of the rice-water mixture, and the rice-water ratio suitable for cooking is set to 1:1.2. /ml, the density of rice grains is about 1.5g/ml. After calculation, the density of rice-water mixture P=m ₁ +m ₂ /(v ₁ +v ₂ ) is about 1.18g/ml, where m ₁ , v ₁ is the mass and volume of water respectively, m ₂ and v ₂ are the mass and volume of meters respectively, therefore, m ₁ /v ₁ =1,

m ₂ /v ₂ =1.5, m ₁ =1.2m ₂ . The detector 5 converts the detected water to the height of the detector 5 into the volume of the rice-water mixture V _x , so the quality of a reasonable rice-water mixture should be M=P*V _x , considering the operational error and cooking taste requirements, the preset The value M should be a range value. The pressure sensor 4 is installed on the body of the pot. If the actual measured value M _x of the pressure sensor falls within the range of the preset water and rice mixture mass M, it means that the ratio of rice to water is reasonable. Otherwise, the user will be reminded to increase or decrease the amount of water , to achieve a reasonable state; if the measured value of the pressure sensor is greater than M, it indicates that the user has added too much rice and reminds to add water, otherwise it is the opposite.
