There are a lot of people who have used the induction cooker, but there are not many people who really understand the induction cooker and know the principle of it. Many people want to know what is the working principle of the induction cooker, and how to maintain the induction cooker in peacetime. After reading our introduction, you will know that the principle of the induction cooker is actually very simple. What is the working principle of the induction cooker? Induction cooker adopts the principle of magnetic field induced eddy current heating. He uses current to generate magnetic field through the coil. When the magnetic force in the magnetic field passes through the bottom of the iron containing pot, it will produce countless small eddy currents, so that the pot itself will heat up at high speed and then heat it. Food in the pot. The electromagnetic wave generated during the operation of the induction cooker is completely absorbed by the shielding layer at the bottom of the coil and the iron containing pot on the top plate. Induction cookers use the principle of electromagnetic induction to heat food. The furnace surface of the induction cooker is a heat-resistant ceramic plate. The alternating current generates a magnetic field through the coil below the ceramic plate. When the magnetic field lines in the magnetic field pass through the bottom of the iron pot or the stainless steel pot, eddy current is generated, and the bottom of the pot is rapidly heated to reach the food. purpose. The working process is as follows: the alternating voltage is converted into direct current by the rectifier, and the direct current is converted into high frequency alternating current exceeding the audio by the high frequency power conversion device, and the high frequency alternating current is applied to the flat hollow spiral induction heating coil, thereby generating High frequency alternating magnetic field. The magnetic lines of force penetrate the ceramic platen of the cooktop and act on the metal pan. In the cooking pot, there is a strong eddy current due to electromagnetic induction. The eddy current overcomes the internal resistance flow of the pot body to complete the conversion of electric energy to thermal energy, and the generated Joule heat is the heat source of cooking. What is the maintenance method? Maintenance method 1. The induction cooker heats the food, frying, frying, boiling, steaming and roasting can be carried out directly. It conforms to the cooking habits of Chinese food, and is small in size and beautiful in appearance. It can be placed and used at will in the kitchen or restaurant. Maintenance method 2. The cooker is made of ferromagnetic material, such as iron pot, enamel pot, stainless steel pot, and requires a certain horizontal area at the bottom. The working principle of the induction cooker is actually not as complicated as we think. To understand the working principle of the induction cooker, in addition to helping us better understand the induction cooker, we can also study our hands-on ability. When the induction cooker is in use, there are some small maintenance skills that can extend the service life. Do not believe you can try. |
A shelf is a flat, horizontal plane used for items that are displayed or stored in a home, business, store, or elsewhere. It is raised off the floor and often anchored to a wall, supported on its shorter length sides by brackets, or otherwise anchored to cabinetry by brackets, dowels, screws, or nails. It can also be held up by columns or pillars. A shelf is also known as a counter, ledge, mantel, or rack.[2] Tables designed to be placed against a wall, possibly mounted, are known as console tables, and are similar to individual shelves.
A shelf can be attached to a wall or other vertical surface, be suspended from a ceiling, be a part of a free-standing frame unit, or it can be part of a piece of furniture such as a cabinet, bookcase, entertainment center, some headboards, and so on. Usually two to six shelves make up a unit, each shelf being attached perpendicularly to the vertical or diagonal supports and positioned parallel one above the other. Free-standing shelves can be accessible from either one or both longer length sides. A shelf with hidden internal brackets is termed a floating shelf. A shelf or case designed to hold books is a bookshelf.
The length of the shelf is based upon the space limitations of its siting and the amount of weight which it will be expected to hold. The vertical distance between the shelves is based upon the space limitations of the unit's siting and the height of the objects; adjustable shelving systems allow the vertical distance to be altered. The unit can be fixed or be some form of mobile shelving. The most heavy duty shelving is pallet racking. In a store, the front edge of the shelf under the object(s) held might be used to display the name, product number, pricing, and other information about the object(s).
