Description

Induction low range {INDUCTION LOW RANGE}

The present invention relates to a low induction stove, and more particularly, to a low induction stove that can prevent damage due to heat and dust and maximize efficiency and ensure maximum stability in cooking.

Induction stove is a vortex current generated by the resistance component (iron component) included in the material of the pot when the magnetic force generated from the coil passes through the bottom of the pot placed on the top plate, and the eddy current generates heat only the pot itself to perform cooking It is a stove. Since the induction stove is not cooked by a flame caused by combustion of fuel, there is no danger of explosion or fire, and it is safe because the surface of the stove is not hot even when cooking. Because of its very large size, it is in the spotlight as a next-generation cookware that can replace a gas stove or a microwave oven. The induction stove as described above has been conventionally applied in such a way as to be manufactured in a small size like a hot plate or attached to a table. However, the induction stove as described above was not practical for home use in the form of a low range. This is because, since the induction stove is electrically operated, the PCB box is embedded, and the internal parts of the PCB box and the induction stove are damaged by the circulation of hot air in the low range, and also included in the circulating air. This is because the operation is disturbed by the fine dust.

Accordingly, the present invention aims to create a commercial induction low-range stove capable of cooking food with high thermal efficiency by preventing damage caused by heat and dust by supplementing the disadvantages of the prior art as described above.

1 shows an external perspective view of an induction low range according to the present invention. As shown in FIG. 1, the induction low range according to the present invention includes a hollow rectangular frame 10 having a flat rectangular parallelepiped shape made of stainless steel, and is vertically upwardly disposed at a rear end of the range 10. A rear support plate 12 is formed which extends and supports the stove to the kitchen wall. A control panel 70 for controlling the entire operation of the stove is formed on the front surface of the stove frame 10, and a ceramic plate 16 is mounted at the center of the upper surface of the stove frame 10. The control panel 70 is formed with a circuit breaker 76 to perform the role of the circuit breaker at the same time as a switch for supplying power to one side, the control operation unit 72 is formed on the other side. The control operation unit 72 is a power switch 73 which is a button switch to start the output of the product, the adjustment knob 74 for adjusting the output of the product, and the output display unit 75 for displaying the output stage of the product It is provided. The hollow stove frame 10 serves as a housing of the internal parts of the induction stove, which will be described later, and the upper surface of the stove frame 10 serves as a plate on which a cooking vessel is placed. The ceramic plate 16 is installed over the upper surface of the stove frame 10 and designates a place where the cooking vessel is placed, and is made of a ceramic material to withstand the high heat of the heated cooking vessel during cooking.

Figure 2 shows a front cross-sectional view of the induction low range according to the present invention. As shown in FIG. 2, the range frame 10 is hollow, and individual parts are suitably arranged in the hollow. The built-in part 14 is inserted into the lower portion of the ceramic plate 16, that is, the upper space inside the hollow stove frame 10. The built-in part 14 has a configuration such as a rectangular parallelepiped box having a low height and an open top surface, and the outer peripheral surface of the upper edge extends outward longer than the bottom surface, so as to form a container shape like a washbasin shape. . The externally extended portion is supported while being mounted on the corresponding inner end of the stove frame 10 which is formed stepped, so that the built-in portion 14 is inserted into the upper space inside the stove frame 10. It is buried. The inside of the upper end of the built-in part is stepped again along the outer circumferential surface, and the edge end of the ceramic plate 16 is placed on the stepped groove. By doing so, the upper surface of the stove frame 10, the upper end of the built-in part 14, and the ceramic plate 16 form a plane with the same height. At this time, the rubber ball 80 is continuously installed at predetermined intervals on the contact surface on the upper edge of the built-in portion in which the ceramic plate 16 is positioned to perform a buffering action when the ceramic plate 16 is placed. It is preferable.

In the built-in portion 14, two working coils 18, 18 'are positioned. The working coils 18 and 18 'form a magnetic field according to the flow of current and interact with iron components of the cooking vessel to be placed on the ceramic plate 16 to heat the cooking vessel. The PCB box 24 is placed on one side of the built-in part 14, that is, the lower space of the hollow stove frame 10. The PCB box 24 has a built-in control circuit for controlling the operation of the working coil (18.18 ').

The other side of the lower space of the hollow range frame 10 is a passage of external air, and a plurality of inflow holes 26 are formed in the bottom surface thereof. The inlet 26 is preferably configured in the form of a slot long in the longitudinal direction. External air flows through the inlet hole 26, and the inlet air is blown by the cooling fans 20 and 20 ′ of the built-in part 14 to cool the heat of the coil as described below. Will be performed. Since the air introduced through the inlet hole 26 contains all the contaminants such as dust and dust in the air, when such contaminants are introduced into the stove as they are, the internal parts may be damaged and induction may occur. There is a risk of reducing the efficiency of the stove and shortening its service life. Therefore, in order to prevent this, it is preferable that an air filter 28 covering the inlet hole 26 is installed.

3 shows a detailed view of the built-in portion 14. The built-in part 14 is provided with two working coils 18.18 'in the horizontal direction. One cooling fan 20, 20 ′ is formed at the front of each of the working coils 18, 18 ′. The cooling fans 20 and 20 'blow a cold air into the working coils 18 and 18' to cool the resistance heat generated by supplying current to the working coils 18 and 18 '. Do this. The cooling fans 20 and 20 'are preferably installed to be inclined vertically from a horizontal plane so that the direction of the blown wind is directly directed to the working coils 18 and 18'. A communication hole 36, 36 ′ is formed at a bottom surface of the built-in part 14 below the cooling fan 20, 20 ′ so as to communicate with a lower space of the hollow stove frame 10. As described in the description of FIG. 1, outside air is introduced through the inflow hole 26 formed in the other bottom surface of the lower space of the stove frame 10, and the inflow air is the cooling fans 20 and 20. It is supplied to the built-in part 14 through the communication hole 36.36 'formed in the lower part. The supplied air is blown to the working coils 18 and 18 'by the cooling fans 20 and 20', and cooling of the working coils 18 and 18 'is performed by the blown air. An air suction fan 22 is installed at the rear portion of the working coils 18 and 18 '. The air suction fan 22 sucks hot air generated from the working coils 18 and 18 'and discharges it to the outside. To this end, a communication hole 36 '' is formed in the bottom portion of the built-in portion 14 below the air suction fan 22 to communicate with the lower space of the hollow range frame 10, and is located at the rear of the lower space. The part is opened or a predetermined exhaust pipe is formed so that the hot air is discharged to the outside. Accordingly, the working coils 18 and 18 'are cooled by cold wind by the cooling fans 20 and 20', and hot air is discharged to the outside by the air suction fan 22 to provide a double cooling effect. Is achieved.

The working coils 18 and 18 'are installed on generally circular working coil mounting plates 50 and 50'. The working coils 18 and 18 'are twisted with several strands of coils so that one large coil bundle is formed in a long rope shape, and the working coils 18 and 18' of the rope shape are the working coil mounting plates 50. 50 '), wound around the center convex portion 52 while drawing a concentric circle, it is wound like a top, which is connected to a power supply via a PCB box. As described above, the working coil mounting plates 50 and 50 'on which the working coils 18 and 18' are wound are fixed to a holder installed on the bottom surface of the built-in part 14. The cradle is composed of one central cradle 56 and one side cradle 58, 58 'installed on each side of the central cradle 56, respectively. Each cradle is formed with a flat portion for supporting the working coil mounting plate (50, 50 '), the lower portion includes an angle portion for supporting the flat portion on the bottom of the built-in portion (14). Rod-shaped protrusions 60 are formed on each of the holders, and two protrusions are formed on both side holders 58 and 58 ', and on the center holder 56, two on each side as shown in the figure. Projections are formed. The protruding portion 60 performs a function of fixing the working coil mounting plates 50 and 50 ', and is penetrated through the through holes 51 formed at the side portions of the working coil mounting plates 50 and 50'. An end of the protrusion 60 penetrating the through hole 51 is clamped by a bolt 54, and the head of the bolt 54 is formed wide enough to cover the through hole 51 so that its width remains. The mounting plates 50 and 50 'are not separated from the protrusion 60. The working coil mounting plates 50 and 50 'may be fixed on the holder as described above, but preferably, the working coil mounting plates 50 and 50' may be elastically supported in a vertical direction. It is possible. This is achieved by installing a spring 62 around the protrusion 60, which covers the spring 62 so as to surround the outer circumferential surface of the protrusion 60, so that the working coil mounting plates 50, 50 ′ are provided with the protrusion 62. The spring 62 is pressed while being fitted to the 60. In this case, when the bolt 54 is fixed, when a constant pressure is applied from above to below the working coil mounting plates 50 and 50 ', the working coil mounting plate 50 may be formed by the elastic force of the spring 62. 50 ') can be made to flow in the vertical direction. As such, the purpose of fluidly elastically supporting the working coil mounting plates 50 and 50 'is that the spacing between the working coils 18 and 18' and the cooking utensils to be positioned thereon is very high in efficiency of the stove. An important factor is influenced by the fact that when a cooking vessel having a different weight is placed on the upper surface of the working coil 18, 18 ′, that is, the stove frame 10, the spring according to the corresponding pressure. By varying the degree of compression of 62, the spacing between the top surface of the stove frame 10 and the working coils 18, 18 'is substantially maintained.

4 is an exploded perspective view of the induction low range according to the present invention, Figure 5 is a flow chart of the air in the interior space of the stove frame 10 is shown.

Hereinafter, a lower space structure inside the stove frame 10 will be described with reference to FIGS. 2 and 4. As shown in the figure, a diaphragm 38 is formed in the lower space of the stove frame 10. The diaphragm 38 is a partition wall separating the PCB box 24 (see FIG. 2) from the built-in part 14, and heat generated from the built-in part 14 is transferred to the PCB box 24, thereby damaging the PCB. It is to prevent the water droplets generated during cooking from penetrating the PCB box 24. The area of the diaphragm 38 is sufficient to cover the PCB box 24 so that heat or water droplets generated in the built-in part 14 do not reach the PCB box 24. The PCB box 24 generates heat on its own, and this heat may be cooled by the outside air introduced through the inlet 26 of the bottom of the stove frame 10 and may include a cooling fan. It may be. The PCB box 24 is preferably inserted between the guide rail fastener 25, as shown (see Figure 2). As can be seen in Figure 4, the lower space is formed with a vertical air barrier film 40 for separating the inside of the stove frame 10 in front and rear. As shown in FIG. 5, the air barrier layer 40 is located at the center of the lower space in the stove frame 10, which is configured to prevent recirculation of hot air. Referring to FIG. 5, the outside air introduced through the inflow hole 26 is introduced into the built-in part 14 through the communication holes 36 and 36 'and is cooled by the cooling fans 20 and 20'. Cool the heat of the working coils (18, 18 '). In addition, the hot heat is sucked by the air suction fan 22 and is discharged back to the lower space through the communication hole 36 '' at the bottom thereof to finally open an opening or a predetermined discharge pipe behind the stove frame 10. Through the outside. However, if there is no air barrier film 40 as described above, the air entering the lower space inside the stove frame 10 by the air suction fan 22 is recycled again through the communication holes 36, 36 '. It is supplied to the cooling fan (20, 20 ') and the hot air is blown from the cooling fan (20, 20') and eventually the cooling fan (20, 20 ') is the original function of cooling the working coil (18, 18') In this case, the temperature of the working coils 18 and 18 'is further increased, which may cause the risk of ash and damage to internal parts and the PCB. Therefore, by providing the air blocking film 40 as described above, the air coming from the air suction fan 22 is discharged to the outside without being recycled anymore.

Also shown in FIG. 4 is a preferred embodiment of an air filter, as shown, an air filter box 29 is formed below the stove frame 10, and the air frame box 29 has the range frame 10. The insertion plate 30 in which the net-shaped air filter 28 is formed to have an area enough to cover the inflow hole 26 formed at the bottom of the bottom surface). The insertion plate 30 including the air filter 28 is detachably mounted in a sliding manner, such as a desk drawer, in the air filter box 29. Therefore, when foreign matter such as dust is caught on the air filter 28, the insertion plate 30 can be removed to easily clean the air filter.

Hereinafter, the overall operating relationship of the induction low range according to the present invention will be described. First, a power supply connecting portion (not shown) is connected to a power source. The power source is preferably a single-phase 220V, 50 / 60Hz 5.2 Kw. Then, the power of the earth leakage breaker 76 of the control panel 70 is turned on, the induction bowl is placed on the ceramic plate 16, and the contents to be cooked are filled therein. When using empty bowls, there is a risk of product damage and fire. After pressing the power switch 73, adjust the output by turning the adjusting knob 74 according to the temperature to be cooked. When the induction stove is operated in the same manner as above, the magnetic force lines are removed from the working coils 18 and 18 '. Occurs and it reacts with the iron in the cooking vessel to heat the food.

According to the induction low range according to the present invention as described above, the built-in portion and the PCB box to generate heat in response to the cooking vessel is configured separately to prevent damage to the PCB due to the heat generated from the built-in portion, install the air filter By blocking the dust in the air, it prevents contamination and damage of internal parts such as PCB due to various contaminants, and recirculation of hot air through the built-in part and PCB box through the air barrier membrane prevents recirculation of hot air. It has an excellent effect of preventing damage to the parts.
