Description
Technical Field
The invention relates to the technical field of cookers, in particular to a double-channel double-fan plasma cooker.
Background
Plasma (plasma), also known as plasma, is an ionized gaseous substance consisting of atoms deprived of part of electrons and positive and negative ions produced by ionization of radicals, a macroscopic electrically neutral ionized gas with dimensions greater than the debye length, whose motion is dominated mainly by electromagnetic forces and exhibits a pronounced collective behavior. The plasma is a good electric conductor, and the plasma can be captured, moved and accelerated by utilizing a magnetic field which is skillfully designed. The development of plasma physics provides new technology and process for the further development of science such as materials, energy, information, environmental space, space physics, geophysical and the like. Plasma is a fourth state of matter different from solid, liquid and gas. A substance is composed of molecules, which are composed of atoms, which are composed of a positively charged nucleus and negatively charged electrons surrounding it. When heated to a sufficiently high temperature or for other reasons, the outer electrons become free electrons free from the nuclei, as if the student after class runs to the playground to play at will. The electrons leave the nucleus, a process known as "ionization". At this point, the material becomes a uniform "paste" of positively charged nuclei and negatively charged electrons, and is thus called a plasma because it is called a "paste" by chance, which is a paste of ions of equal total positive and negative charge and therefore nearly electrically neutral.
The plasma stove is a novel stove which utilizes the characteristics of plasma, uses high-voltage electricity to breakdown air to form thermal plasma, converts electric energy into heat energy, finally obtains thermal plasma beams with ideal length and function, and generates the thermal plasma beams with similar flame characteristics to heat a pot for cooking.
Since the plasma oven needs to convert an external power supply into a high voltage, for example, 220V ac into a high voltage of about 10KV for discharging, a circuit portion of the plasma oven needs to be provided with a voltage transformation circuit unit for voltage conversion in addition to an electric control unit for power supply and overall machine control, and both of the two circuits generate heat when the plasma oven works, especially the heat generated by the voltage transformation circuit unit is larger.

Referring to fig. 4, the cooking range 2 of the plasma range 100 of the present invention further includes a high temperature-resistant insulating plate 15 positioned above the installation case, and the high temperature-resistant insulating plate 15 installs the plurality of discharge electrodes 4.
In the embodiment of the invention, the upper end of the mounting shell 12 supports the high temperature resistant insulating plate 15 and the pot support 8. The high temperature resistant insulating plate 15 can prevent heat loss of the pan bottom on one hand, and can prevent heat from flowing downwards to the mounting shell 6 on the other hand, so that the temperature of the mounting shell 6 is prevented from being too high to influence the voltage transformation circuit unit 7 in the mounting shell. Meanwhile, the high temperature-resistant insulating plate 15 also serves to mount and support the plurality of discharge electrodes 4.
Preferably, a negative electrode 16 for forming a discharge circuit with the plurality of discharge electrodes 4 is further disposed above the high temperature resistant insulating plate 15 of the plasma cooker 100 of the present invention. The negative electrode 16 is connected to the power ground on the circuit of the electronic control unit 3.
The negative electrode 16 is independently arranged in the embodiment of the invention, so that the cookware 300 is not used as a part of an electric loop any more in the using process, the method that the plasma beam is generated between the discharge electrode and the cookware in some existing plasma cookers 100 is changed, and the plasma beam is generated between the discharge electrode and the negative electrode, so that metal and nonmetal cookware can be used on the plasma cooker 100, and the problems that the cookware is broken down and the service life of the cookware is influenced due to the fact that the cookware is directly hit on the bottom of the cookware under the long-time action when the cookware is used as the negative electrode are avoided.
Preferably, as shown in fig. 10, the cooking range 2 of the plasma cooking range 100 of the present invention further includes a liftable grounding device 18 disposed above the mounting housing 6, the liftable grounding device 18 is provided with an extended end 181 capable of being lifted up and down elastically in a protruding manner for making elastic contact with the bottom of the pot 300, and the extended end 181 is electrically grounded. The protruding terminal 181 is electrically grounded such that the protruding terminal 181 is finally connected to the ground and the potential is zero.
For safety, the fire should be turned off immediately when the pot 300 is completely separated from the plasma cooker 100 in the prior art. Since in the prior art, once the pot 300 leaves the cooking range 2, the pot 300 is no longer grounded, and if the fire is not turned off, the discharge electrode 4 may discharge toward the bottom of the pot 300 that leaves the cooking range 2, so that the pot 300 is charged and an electric shock is easily caused. Therefore, in the prior art, a user cannot lift the pot (namely, the pot is lifted and separated from the cooker and jolts repeatedly, so that the cooked food is heated sufficiently) during cooking.
The lifting grounding device 18 arranged on the plasma cooker 100 can lift the extending end 181 and is in elastic contact with the bottom of the cooker 300, so that even if the cooker 300 is lifted away from the cooking range 2 in the extending range of the extending end 181, the cooker bottom is also in contact with the extending end 181, and the extending end 181 is grounded, so that the cooker 300 is grounded and has no potential safety hazard, and then, even if the cooker 300 is lifted away from the cooker 300 and is higher than the highest extending height of the extending end 181, the discharging electrode 4 cannot discharge towards the cooker bottom because the cooker bottom of the cooker 300 is far enough away from the discharging electrode 4, the cooker 300 is safe, and a user can turn the cooker to be cooked without potential safety hazard. The highest protruding height of the protruding end 181 can be designed by experiment, for example, the height of the highest protruding height of the protruding end 181 from the plane of the discharge electrode 4 is 50mm or more.
Meanwhile, due to the safety function of the lifting grounding device 18, after the cookware 300 leaves the cooking range 2, the plasma cooking range 100 does not need to be immediately turned off, so that the defect that the cooking is affected because the cookware needs to be turned off and on repeatedly to ensure safety to cause discontinuous heat when the cookware needs to be turned over in the prior art is avoided.
According to the double-channel double-fan plasma stove 100 provided by the embodiment of the invention, the first heat dissipation channel 9 communicated with the front side and the rear side of the installation shell 6 and the second heat dissipation channel 10 communicated with the front side and the rear side of the electric control unit 3 are respectively arranged in the base 1, and the corresponding heat dissipation fan, the air inlet and the air outlet are respectively and independently arranged to independently blow heat in each heat dissipation channel out of the base 1.
The above description is only for clearly illustrating the invention and is not therefore to be considered as limiting the scope of the invention, and all embodiments are not intended to be exhaustive, and all equivalent structural changes made by using the technical solutions of the present invention or other related technical fields directly/indirectly applied under the concept of the present invention are included in the scope of the present invention.
