Problems solved by technology

[0004] However, due to the altitude, the boiling point of the liquid is quite different. For every 300 meters above sea level, the boiling point of the liquid will drop by one degree. If the temperature set by the equipment control program is fixed, it will cause the work in high altitude areas to boil all the time, and the liquid may overflow and be wasted. electric energy
At the same time, the equipment cannot adapt to the change of boiling point in high-altitude areas, which will cause the food to be cooked for a short time and cannot be cooked.

Embodiment 1

[0031] A control method for a high-altitude adaptive liquid heating device, including raising the temperature to a first target temperature T 0 stage, thermal uniformity waiting stage, altitude adaptation to micro-boiling stage, compensation stage, and specifically includes the following steps:

[0032] A. Warm up to the first target temperature T 0 Phase: heating the liquid temperature to the first target temperature T 0 ; Among them, the first target temperature T 0 Generally, it is set according to the temperature of the liquid before heating. The first target temperature T 0 It needs to be higher than the temperature before the liquid is heated. If the temperature of the liquid before heating is between 10°C and 30°C, the first target temperature T can be set 0 It is about 50°C to 60°C. If the temperature of the liquid has reached about 50°C before heating, the first target temperature T 0 At least it should be set to about 60°C, generally it can be set between 60°C an...

Embodiment 2

[0043] This example is a specific process of using the above method to heat water to cook potatoes, and in this example, the temperature of the water before heating after putting the potatoes in is 15°C, the device is used in an area with an altitude of about 900 meters, and the water in this area The boiling point is 97°C, and the rated power of the heating device is 400W.

[0044] Step 1: Put the potatoes and water in the heating device for heating, so that the water will be heated to 70°C when the heating device is heated with a rated power of 400W;

[0045] Step 2: Stop heating, wait for 20s and then measure the water temperature. At this time, the measured water temperature rises to 73°C;

[0046] Step 3: Since the actual boiling point of local water is not known during specific use, it is necessary to calculate the difference between the current temperature and the boiling point of water at standard pressure of 100°C, which is 27°C, so use The heating device heats the w...

Abstract

The invention discloses a control method of a high-altitude self-adapting liquid heating device. The control method comprises a stage of heating to a first target temperature T0, a thermal uniformitystanding stage and an altitude adapting micro-boiling stage. According to the control method, liquid can be heated to a liquid boiling point below the altitude by virtue of the heating device under different altitude conditions and can be automatically heated with relatively low power after the liquid reaches a micro-boiling state, so that the consumption of electric energy caused due to excessiveboiling can be reduced, and meanwhile, the highest temperature of the liquid below the elevation line can be maintained.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a control method for a high-altitude self-adaptive liquid heating device. Background technique [0002] With the advancement of technology, all kinds of home appliances have entered thousands of households, and heating products, as a food-related category, account for a high proportion of households. [0003] In the prior art, the heating device is generally controlled by setting a fixed heating temperature. The principle of the control method of the heating device is to control the heating device to stop heating after detecting that the heating device has heated the liquid to its boiling point, otherwise , the heating device will continue to heat the liquid. For example, the general heater is set to heat the water until it stops when the water is heated to 100 degrees Celsius. [0004] However, due to the altitude, the boiling point of the liquid is quite different. For every 3...
