Here’s our guide to the essential appliances for a cozy summer home.

In a cosy kitchen, the stove is the central piece of culinary equipment that transforms bland ingredients into mouth-watering delicacies. However, kitchen safety is always a topic that can not be bypassed, stove dry burning is one of the major hidden dangers. Dry burning will not only shorten the service life of the stove, but also may cause fire and bring serious losses to the family. However, now cheap stoves are also equipped with anti-drying technology, for kitchen safety added a safeguard. Next, let's take a closer look at the technology.

I. The principle of technology

The core of oven anti-drying technology lies in the accurate perception of temperature changes. When the stove is working properly, the water and food inside the cooker will absorb heat, and the temperature of the cooker will be maintained in a relatively stable range. But once the dry situation, the bottom of the pot and the stove flame in direct contact, heat can not be effectively absorbed, the temperature will rise rapidly. The anti-drying device acts as a sensitive temperature sentry, with a built-in temperature sensor that monitors the bottom of the PAN in real time. These sensors usually use thermistors, thermocouples and other components, they are extremely sensitive to temperature changes, temperature signals can be converted into electrical signals. When the temperature exceeds the set safety threshold, the electrical signal will change significantly, triggering the subsequent protection mechanism.

II. Mode of realization

1. Thermistor type: Thermistor is a resistance with the temperature change and significantly change the value of the element. In the anti-drying system of inexpensive cooktops, the thermistor is installed near the bottom of the pot. When the temperature of the pot rises, the resistance of the thermistor decreases rapidly, and the current in the circuit changes. When the control system detects this change, it will judge it as dry burning and immediately cut off the gas supply or stop heating.

2. Infrared Temperature Measurement: infrared temperature measurement technology using the characteristics of infrared to measure the temperature of objects. The infrared sensor on the stove emits infrared radiation and receives the reflected infrared radiation from the bottom of the pot. By analyzing the intensity and frequency of the reflected infrared radiation, the temperature of the bottom of the pot is calculated. When the temperature rises abnormally, the sensor transmits the signal to the control system to trigger the anti-dry-out protection.

3. Mechanical bimetal: a bimetal is made of two Coefficient of thermal expansion metals bonded together. When the temperature rises, the expansion degree of the two metals is different, which leads to the bending deformation of the bimetal sheet. In cheap cookstoves, bimetallic sheets are connected to mechanical actuators. When the temperature exceeds the set value, the bimetallic plate is bent to push the transmission device, cut off the gas valve, and realize the function of anti-dry burning.

III. Characteristics of advantages

1. Economical and practical: the biggest advantage of the anti-dry-burning technology of the stove is the lower cost. By optimizing the design and using cost-effective components, this technology can be applied to affordable stove products. This allows the majority of ordinary families do not have to spend high costs, will be able to enjoy the security brought about by anti-drying, greatly improving the popularity of kitchen safety technology.

2. Easy to operate: the technology is easy to understand and does not require users to set up and debug complex. The user only needs to use the stove normally, and the anti-drying device will work automatically in the background. In the event of a dry-out, the system will automatically take action without manual intervention by the user, even if the user is not familiar with the electronic equipment can easily get started.

3. High Reliability: after a large number of experiments and practical use of verification, the anti-drying technology of cheap stoves has high reliability. These technologies can work stably under different environmental conditions, accurately judge the dry burning situation and take timely protective measures. At the same time, the utility model has the advantages of simple structure, low failure rate and relatively low maintenance cost.

Conclusion

The anti-dry-burning technology of the stove is the product of the perfect combination of science and technology and life. With accurate temperature perception and diversified implementation methods, it brings economical and reliable security for home kitchens. In the pursuit of food at the same time, we do not have to worry about the problem of dry stove. With the continuous progress of technology, I believe that the anti-dry burning technology of cheap stoves will continue to improve and develop, and create a safer and more convenient kitchen environment for our lives, let's indulge in the pleasure of cooking in the kitchen.
