Description

Induction range {Induction range}

The present invention relates to an induction range, and more specifically, to an induction range with improved exhaust structure and safety.

In the past, gas ranges using gas were widely used. Recently, as induction ranges that heat and cook food using induction heating have been commercialized, induction ranges are being widely used not only at home but also in the kitchens of large restaurants.

The induction heating method generates a magnetic field by supplying high-frequency current to an induction coil. The magnetic field generated by the coil induces an eddy current in the heating element located above the coil, and the eddy current is converted into heat by the resistance of the heating element.

The induction heating method has high energy efficiency compared to conventional gas and electric heating methods, has little risk of fire, and does not generate harmful gases such as carbon monoxide or carbon dioxide, so it is attracting attention as a highly efficient, eco-friendly cooking appliance.

However, in the case of such a conventional induction range, a number of vent holes are formed in the front, side, and rear parts for ventilation, and a suction fan to suck in outside air is installed on the lower surface of the induction range main body. There was a problem that it was difficult to set the height of the induction range low.

In the case of Registration Patent No. 10-1791183 (registration date: October 23, 2017), as shown in Figure 1, a suction fan is formed at the bottom of the induction range unit (U), and in Figures 3 and 4. As shown, a number of vent holes are formed in the front part, the side part, etc., so a number of legs are installed on the induction range unit (U) and it is installed at a high position from the ground.

In particular, in the case of induction ranges manufactured for commercial use, if the induction range unit (U), such as the above conventional registered patent, is installed in a low position from the floor of the business, water may enter the induction range unit (U) through the vent hole during water cleaning. If it flows into the inside of the induction range unit (U) and touches a number of electronic devices or wires placed inside the induction range unit (U), it may corrode or damage the electronic devices, which could become a safety problem.

This is a rear perspective view of an induction range according to an embodiment of the present invention, deleted. For convenience of explanation, the x-axis direction in FIG. 1 is defined as the front-to-back direction, the y-axis direction is defined as the up-down direction, and the z-axis direction is defined as the left-right direction.

An induction range according to an embodiment of the present invention may be configured to include a case 10, an upper cover 20, an induction heating coil 30, and a control unit 40.

Case 10 may be formed as a substantially rectangular parallelepiped-shaped cylinder with an open top.

The upper front part of the case 10 may be provided with a power button 110 of the induction range, a temperature control device 111, and a display 112 for displaying the current temperature and the set temperature.

An opening 120 is formed in the lower part of the front part of the case 10, and a lower door 122 is provided to be hinged and rotatable in the lower part of the front part of the case 10 to open and close the opening 120. A replaceable filter 121 can be installed inside the lower door 122 to filter out foreign substances flowing in from the outside, and the lower door 122 has a plurality of vent holes (H) for the inflow of outside air. is formed Air flowing in through the lower door 122 passes through the filter 121 and moves into the case 10 through the opening 120.

In the case 10, a front blocking wall 130 is installed at a predetermined distance rearward from the opening 120. As shown in one embodiment of FIGS. 5 to 7 , the front blocking wall 130 may be made of a plate-shaped member that protrudes upward from the lower surface of the case 10 by a predetermined height. The front blocking wall 130 blocks water or foreign substances flowing in from the opening 120. Since the filter 121 is installed in front of the opening 120, most foreign substances can be filtered out, but water or fine foreign substances can pass through the filter 121. In order to prevent water or foreign matter that has passed through the filter 121 from flowing into the case 10, a front blocking wall 130 is provided at the rear of the opening 120.

However, the height of the front blocking wall 130 is adjusted so that a predetermined gap D1 is formed between the front blocking wall 130 and the upper surface of the case 10 so that the inflow of external air is not hindered by the front blocking wall 130. It is desirable to form the height equal to or slightly higher than the height of the opening 120. Additionally, a plurality of vent holes (H) may be formed at the top of the front blocking wall 130 to allow air flowing in from the opening 120 to pass through.

As shown in FIG. 6, the front blocking wall 130 extends across the left and right sides of the case 10. Accordingly, even if water or foreign substances enter through any part of the opening 120 of the case 10, they are blocked by the front blocking wall 130.

Meanwhile, a rear blocking wall 140 protruding upward from the lower surface of the case 10 is formed at a position spaced forward by a predetermined distance from the rear portion of the case 10. The rear blocking wall 140 separates the exhaust space 160 disposed at the rear of the case 10 from the space inside the case 10 (i.e., the foreign matter blocking space 150).

Like the front blocking wall 130, the rear blocking wall 140 is a plate-shaped member and extends across the left and right sides of the case 10. The height of the rear blocking wall 140 may be formed higher than the front blocking wall 130 in order to prevent the air exhausted to the outside from the exhaust space 160 at the rear of the case 10 from flowing back into the case 10. and may preferably extend to the top of the case 10 as shown in FIGS. 5 and 7.

However, the height of the rear blocking wall 140 is located below the lower surface of the upper cover 20 covering the case 10, so that there is a predetermined gap between the lower surface of the upper cover 20 and the rear blocking wall 140 ( It is desirable to form D2 so that a portion of the air inside the case 10 moves to the exhaust space 160 at the rear of the case 10 through this gap D2. This gap D2 allows air moving upward inside the case 10 to flow smoothly into the exhaust space 160 without moving downward.

At least one exhaust fan 141, 142 is installed on the rear blocking wall 140 to move the air inside the case 10 to the rear of the case 10. Preferably, as shown in FIGS. 5 to 7, two exhaust fans 141 and 142 are installed at a height below the middle of the rear blocking wall 140 to suck air inside the case 10 to exhaust the case 10. ) Move it to the rear exhaust space (160). As described above, the air moving upward among the air inside the case 10 moves to the rear exhaust space 160 through the gap D2 between the rear blocking wall 140 and the upper cover 20, and moves to the rear exhaust space 160, (10) The air moving to the middle part and below of the internal air is moved to the exhaust space 160 through the exhaust fans 141 and 142, so that the air inside the case 10 can be discharged quickly and efficiently. do.

In addition, according to an embodiment of the present invention, as shown in FIGS. 5 to 7, an exhaust duct 143 is installed at the rear of the rear blocking wall 140 to exhaust the exhaust space 160 through the exhaust fans 141 and 142. The air moving to is mainly moved to the lower part of the case 10 through the exhaust duct 143, so that the air can be smoothly discharged through the bottom of the case 10.

In the case of the exhaust space 160 at the rear of the case 10, vent holes (H) are formed on the left and right sides and the bottom, so that the air flowing into the exhaust space 160 at the rear of the case 10 flows smoothly to the outside. The air inside the exhaust space 160 is prevented from flowing back into the space inside the case 10 by the rear blocking wall 140.

According to an embodiment of the present invention, front and rear, left and right, and A barrel-shaped foreign matter blocking space 150 with a sealed lower portion is formed, and a control unit 40 is disposed inside this foreign material blocking space 150.

The control unit 40 is connected to an external power source and serves to supply power to generate a high-frequency magnetic field in the induction heating coil 30 and to control the high-frequency magnetic field generated in the induction heating coil 30. The power button 110 ), the temperature control device 111, the display 112, and the fans 31, 141, and 142 are also electrically connected to supply power to each device and control the operation of the device. As shown in FIG. 6 as an example, an exhaust fan 142 is disposed at the rear of the control unit 40 to exhaust heat generated inside the control unit 40 into the exhaust space 160 at the rear of the case 10. It can be released.

In the case of the induction range of the present invention, the control unit 40, cables, and various electronic devices are placed inside the foreign matter blocking space 150 so that they can be protected from external water or foreign substances, so as shown in FIGS. 1 to 7, the case ( 10) The lower leg 170 may be formed very short and the overall height may be formed very low.

In the case of conventional induction ranges, in businesses where water cleaning is frequent, water flows into the induction range through the vent hole at the bottom of the induction range, so the legs had no choice but to be made very high. However, in the case of the present invention, the case (10) This problem of the prior art is solved by forming a space 150 to block foreign substances inside.

Meanwhile, according to one embodiment of the present invention, the upper cover 20 can be installed to be openable and closed from the case 10 by coupling the hinge 21 to the case 10, and the lower surface of the upper cover 20 has an inductive A cooling fan 31 for cooling the heating coil 30 and the induction heating coil 30 may be installed and supported on the jig 32.

In addition, a reinforcing bar 180 may be disposed in a rectangular ring shape at the top of the upper case 10. When the upper cover 20 covers the upper part of the case 10, the reinforcing bar 180 is attached to the upper cover 20. ) is placed in contact with the lower surface of the. If a heavy pot or cooking vessel is placed on the top of the top cover 20, the top cover 20 may be bent. In the case of the present invention, the reinforcing bar 180 is in contact with the lower surface of the top cover 20. Improves rigidity. Therefore, the induction range according to an embodiment of the present invention has the advantage of being able to firmly support the cooking vessel even when a large-capacity cooking vessel is used.

Generally, a lot of force is required to place a large-capacity cooking vessel, such as a pot, on an induction range. In particular, moving a cooking vessel to a high induction range with food inside it becomes a very difficult and dangerous task. Additionally, the heavy weight of the cooking vessel and its contents may cause the top plate of the induction range to bend. However, according to the embodiment of the present invention, the induction range can be formed low and even heavy cooking containers can be stably supported by the reinforcement bar 180 at the top of the case 10, so it can be used in kitchens such as businesses that use large-capacity cooking containers. It can be used safely and conveniently.

Figure 5 shows the exhaust process of an induction range according to an embodiment of the present invention. Negative pressure is generated by the operation of the exhaust fans 141 and 142 installed on the rear blocking wall 140 of the induction range and the cooling fan installed on the induction heating coil 30, which causes the opening 120 of the case 10 along the A1 path. External air is sucked into the case 10 through. Since all inhaled air enters the inside of the case 10 through the filter 121 installed in front of the opening 120, foreign substances are primarily filtered out.

The air passing through the opening 120 is blocked by the front blocking wall 130 and moves upward along the A3 path to enter the inside of the case 10 through the space D1 between the front blocking wall 130 and the upper surface of the case 10. Foreign matter flows into the blocking space 150. At this time, air may also be introduced through a plurality of vent holes (H) formed in the upper part of the front blocking wall 130 along the A2 path. Since water and foreign substances are secondarily blocked by the front blocking wall 130, the air entering the foreign material blocking space 150 inside the case 10 has almost no water particles or foreign substances.

Some of the air flowing into the foreign matter blocking space 150 inside the case 10 rises to the top by the cooling fan along the A3 path to cool the induction heating coil 30, and the other part flows into the control unit along the A5 path ( 40) direction to cool the control unit 40, and another part flows into the lower part of the control unit 40 or other spaces along the A2 and A4 paths to cool the inside of the case 10.

Some of the air that has passed through the foreign matter blocking space 150 of the case 10 crosses the rear blocking wall 140 along the A6 path and passes through the gap D2 between the rear blocking wall 140 and the upper cover 20. It flows into the exhaust space 160 at the rear of the case 10 and is discharged to both sides 135, 136 of the exhaust space 160 along the A8 path, or through a vent hole formed on the lower surface of the exhaust space 160 along the A7 path ( H), the other part flows into the rear exhaust space 160 through the exhaust fans 141 and 142, and is guided by the exhaust duct 143 to the exhaust space 160 along the path A7 to A8. ) is discharged to the outside through the vent hole (H) formed on the lower surface and side part.

Therefore, in the case of an induction range according to an embodiment of the present invention, the air sucked in from the front of the induction range is discharged through both sides and the bottom of the exhaust space behind the induction range, so the exhaust process can be performed smoothly and the induction range There is an advantage in that you can cook in a comfortable environment because the exhaust hot air does not reach the front cooking space.

In addition, in the case of the induction range of the present invention, even if multiple induction ranges are installed with the sides adjacent to each other, only the exhaust spaces at the rear of the adjacent induction ranges are connected to each other, so that air is discharged only through the exhaust space, and air is discharged from the sides of the remaining induction ranges. Because there is no exhaust, the exhaust does not interfere with each other even if multiple induction ranges are installed adjacent to each other.

So far, the present invention has been examined focusing on its preferred embodiments. A person skilled in the art to which the present invention pertains will understand that the present invention may be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered from an illustrative rather than a restrictive perspective.
