Safe plasma stove

Abstract

The invention discloses a safe plasma stove. The safe plasma stove comprises a base, a cooking range and an electric control unit, wherein a plurality of discharging electrodes are arranged in the cooking range; a transformation circuit unit is arranged in the base, and electrically connected with the electric control unit and the discharging electrodes; a ground detection circuit and a total electric leakage detection circuit are arranged on the electric control unit; the ground detection circuit is used for detecting whether all protection ground points of the plasma stove are grounded effectively or not; the total electric leakage detection circuit is used for detecting the difference between inflow current and outflow current at the positive electrode and negative electrode of the electric control unit in order to judge whether the plasma stove is in a current leakage state or not; the ground detection circuit is electrically connected with a protection ground wire in a three-wireplug; a liftable grounding device is also arranged in the cooking range; and an elastically-liftable extending end is arranged on liftable grounding device for being in elastic contact with the bottomof cookware. The safe plasma stove is enabled to perform food tossing operation safely, and has ground detection and leakage detection multiple protection.

Description

technical field [0001] The invention relates to the technical field of cookers, in particular to a safe plasma cooker. Background technique [0002] Plasma, also known as plasma, is an ionized gas-like substance composed of positive and negative ions generated after ionization of atoms and atomic groups after partial electron deprivation. It is a macroscopically neutral ionized gas whose scale is larger than the Debye length. Movement is dominated by electromagnetic forces and exhibits remarkable collective behavior. Plasma is an excellent electrical conductor and can be trapped, moved and accelerated using cleverly designed magnetic fields. The development of plasma physics provides new technologies and processes for the further development of materials, energy, information, environmental space, space physics, geophysics and other sciences. Plasma is the fourth state of matter distinct from solids, liquids and gases. Matter is made of molecules, molecules are made of ato...

Problems solved by technology

Therefore, in the current plasma stove, when the plasma stove and the pan are completely separated from the stove, the method of immediately turning off the fire is simply and rudely adopted to prevent electric shock. Cut off the power supply and turn off the fire, then put it back into the pot and then control the fire, so that the heat supply to the bottom of the pot is not continuous, so the cooking operation of the existing plasma stove can not be carried out normally.

[0007] 2. The existing plasma cooker simply grounds the cooker shell, but does not check whether the entire circuit, especially the external power supply part, is effectively grounded

However, in some old residential areas / rural areas, many residential houses did not strictly implement the installation of grounding wires in accordance with national standards when they were connected to the home. The exposed metal part is grounded. If it is used in the above-mentioned old residential area without grounding wires, the effect of grounding protection cannot be achieved, and there are potential safety hazards.

[0008] 3. The existing plasma cooker is only connected to the leakage switch at the entry line, and there is no leakage detection for the internal circuit of the cooker, which also has potential safety hazards
