Electric Kettle Solution
The electric kettle is used to quickly boil tap water. It is a new type of household drinking water appliance developed in recent years after electric water boilers, electronic thermos bottles, and hot and cold water dispensers. It is suitable for homes, offices, hotels, etc. Due to its portability and safety, it is favored by more and more people, and the market prospect is huge. At present, the market competition for electric kettles is becoming more and more fierce. Due to the low barriers to entry, high profits, and short operating cycles, the industry monopoly has not yet formed, and electric kettles are favored by home appliance manufacturers. Many manufacturers are working hard to improve the technical content and performance of electric kettles, so as to make the use of electric kettles more convenient and safe.
Electric kettle products use stainless steel heating plate. The new technology of rotation, the separate design of the kettle body and the power supply and other methods ensure that the electric kettle will automatically cut off the power after boiling, and prevent dry boiling. fast.
1. The technical principle of the electric kettle solution
The main advantages of electric kettles are trendy appearance, convenience, freshness and sanitation, safety and reliability, and distinctive features. The main working principle of the electric kettle is that about a minute after the power is turned on, the water temperature gradually rises to 100°C, the water starts to boil, and the steam hits the bimetal on the steam switch. Switch contacts disconnect power. If the steam switch fails, the water in the pot will continue to burn until the water is boiled dry, and the temperature of the heating element will rise sharply. There are two bimetallic plates at the bottom of the heating plate, and the temperature will rise sharply due to heat conduction, expand and deform, and break. Turn on the power. Therefore, the safety protection device of the electric kettle is designed very scientifically and reliably, which is the triple safety protection principle of the electric kettle. The working principle of the electric kettle product designed in this paper is to use the British industrial thermostat, and the electronic board program control center controls the clutch of the relay through the temperature information fed back by the thermal electronic on the thermostat, thereby controlling the working power of the heating plate.
2. Functional design of electric kettle
1. Water boiling function
Plug the base into the power supply, press the switch button, and the base starts to be powered on. If the pot body is not placed on the base, there will be no function on the base. Put the pot body filled with water on the base, the whole machine will be in standby mode, and the temperature function is in the default boiling state, press the selection button to choose a different temperature, after selecting the temperature, press the switch button, the heating plate Turn on the power, the whole machine starts to boil water, the thermistor will continuously feed back the temperature information to the information control center, when the temperature reaches the selected temperature, the information control center will make judgments and actions based on the information fed back by the thermistor , so that the relay is automatically disconnected, the power supply of the heating plate is cut off, and the whole machine returns to the default boiling state of standby.
2. Heat preservation function
The heat preservation function of this product is an independent function. Plug the base into the power supply, press the switch button, and the base will start to be powered on. If the pot body is not placed on the base, there will be no function on the base. Put the body of the pot filled with water on the base, the whole machine will be in standby mode, and the temperature function is the "boiling" function in the default state. At this time, there are two main ways to keep warm. You can choose any temperature at this time, but if Press the switch button to boil water For tap water, then press the keep warm button to keep warm, the kettle will first heat the water to 100°C and then keep the water at 55°C, 80°C, 95°C, which caters to the needs of the market, 55°C For milk powder, coffee at 80°C, and tea at 95°C, you can choose any temperature at this time, but if you press the keep warm button first to boil water and keep warm for direct drinking, the kettle will directly heat the water to the required temperature level, Keep warm at 55°C, 80°C, 95°C.
3. Design of main parts of electric kettle
According to the functional analysis of the electric kettle, the main functional components in the electric kettle are the temperature controller, built-in probe and heating plate and other parts.
1. Thermostat design
As the main core component, the thermostat of the electric kettle plays a very important role. The life of the thermostat directly affects the life of the electric kettle. The biggest difference between domestic thermostats and imported thermostats lies in the production process, materials, and service life of the product. Comparing the two, the thermostat life of imported electric kettles is about 20,000 times, while the life of domestic electric kettle thermostats can reach at least 5,000 times, and the safety factor of imported electric kettle thermostats is relatively high. The temperature controller parts in this product adopt the technology temperature controller imported from the UK, which can control the temperature accurately, ensure boiling, and have the function of preventing dry burning.
2. Built-in probe design
The built-in probe of the electric kettle is one of the main functional components of the product. By adopting the sensing technology of the built-in intelligent temperature-sensing probe, the electric kettle can realize free temperature adjustment from ℃ to ℃, control the temperature accurately and in place, and ensure the precise control requirements of different temperatures.
3. Heating plate design
The heating plate is the main part of the electric kettle, and its main function is to heat and keep warm the water in the kettle. The electric kettle is called a rotary electric kettle. This kind of electric kettle replaces the heating tube with a heating plate, and hides the heating plate at the bottom of the kettle so that it does not come into direct contact with water. It can realize the one-time anti-dry protection function and the connector is placed in the center of the base and the chassis of the kettle body, so that Both can. Arbitrary docking, more convenient to use. With the development of thermostat technology, rotary electric kettles have more and more additional functions, such as precise automatic power off, heat preservation and other functions, making the use of electric kettles more humane. At present, rotary electric kettles have nearly a share in the European market, and the above products sold in the Chinese domestic market are also rotary products. The heating plate in this product uses stainless steel heating plate. The new technology of rotation makes the kettle body and the power supply separate design, so as to ensure that the electric kettle will automatically cut off the power after boiling, prevent dry boiling, and greatly improve the safety and portability of the product.
After the main functional parts are designed, finally, according to the internal structure, the appearance of the multifunctional kettle is designed with software assistance. Using software to design the body of the multifunctional electric kettle. We use lines to outline the general outline of the fuselage, and then use the lines to construct surfaces so that the surfaces show the outline of the entire fuselage. After observing and setting the parameters of the outer contour of the fuselage, and confirming that the fuselage meets the designer's requirements, we materialize the originally determined shape of the fuselage. The pot body is made of stainless steel, which has the advantages of simplicity, beauty, generosity, and easy cleaning. In the design of the handle of the pot body, ergonomics is used to fully consider the comfort of the user.
