Definitions
- Some high frequency cooking devices are equipped with a turntable on which food is placed.
- the turntable must rotate stably while maintaining a predetermined position.
- the present invention has been made in view of the above points, and in a high-frequency cooking apparatus that supports a turntable with a roller stay, even if a force is applied to the edge of the turntable, the inclination is such that the roller table is detached from the roller stay.
- An object of the present invention is to provide a high frequency cooking device that does not occur on a turntable.
- the high-frequency cooking device includes a heating chamber for heating food, and a roller stay disposed on the bottom wall of the heating chamber, on which a turntable is placed and rotated.
- a tilt prevention member disposed between the lower surface of the turntable and the bottom wall of the heating chamber, and the tilt prevention member prevents the turntable from tilting more than a predetermined angle.
- FIG. 5 is a partial vertical sectional view similar to FIG. 4, showing a state different from FIG. 4.
- FIG. 9 is a partial vertical sectional view similar to FIG. 8, showing a state different from FIG. 8.
- FIG. 10 is a partial vertical sectional view similar to FIG. 10, showing a state different from FIG. 10.
- FIG. 13 is a partial vertical cross-sectional view similar to FIG. 12 for explaining the disadvantages of the conventional structure.
- the window 11 is formed on the door 11 so that the inside of the heating chamber 20 can be seen.
- the window 13 is fitted with a door screen 14 in which punching metal is sandwiched between two glass plates to prevent leakage of radio waves while maintaining transparency.
- the door 11 is provided with measures for preventing radio wave leakage, and a gasket for preventing gas leakage from the heating chamber is attached and a lock device for keeping the closed state is provided. Detailed description will be omitted.

- a display device 15c made of a liquid crystal panel is disposed above the membrane switch 15a.
- the housing 10 is supported on a table or table by legs 16 (see FIG. 2).
- the leg portion 16 has a total of four grounding portions 16a at the left and right positions on the front side and the back side, and forms a four-point support.
- a high frequency generator (magnetron) 21 is attached to the outer surface of the right side wall of the heating chamber 20.
- the high frequency generator 21 supplies a high frequency to the inside of the heating chamber 20.
- the high frequency generator 21 is located in a space in the housing 10 that is the back side of the operation unit 15. In the same space, a circuit board (not shown) constituting a control device described later is also arranged.
- a lighting device 22 for illuminating the inside of the heating chamber 20 is also arranged on the outer surface of the right side wall of the heating chamber 20.
- the illuminating device 22 uses a light emitting diode (LED) as a light source.
- the right side wall of the heating chamber 20 has a number of light transmitting holes 24 through which light emitted from the plurality of LEDs 23 passes, and is formed in a rectangular group. ing.
- the size and arrangement of the light transmission holes 24 are the same as the punching metal holes of the door screen 14, and radio waves do not leak from there.
- An exhaust port 17 composed of a collection of small holes is formed on the right side surface of the housing 10, and a cooling fan 18 is disposed inside the exhaust port 17.
- a cooling fan 18 is operated, the air inside the housing 10 is exhausted from the exhaust port 17, and as a result, the air outside the high-frequency cooking device 1 is sucked from an air inlet (not shown) provided at another location of the housing 10. It is. The sucked air flows toward the cooling fan 18, and the air flow cools heat-generating components such as the high-frequency generator 21, the LED 23, and the circuit board.
- a turntable 30 on which food to be heated is placed is disposed.
- the object to be heated by the high-frequency cooking device 1 includes solids, fluids, and liquids, but in this specification, the word “food” is used as a representative name thereof.
- the turntable 30 is a planar glass member whose upper surface is shallow and recessed like a dish.
- the turntable 30 is supported on the bottom wall of the heating chamber 20 by a roller stay 31. As shown in FIG. 5, the roller stay 31 is one in which one roller 31c is rotatably held at the tip of three arms 31b protruding radially from the central hub 31a at 120 ° intervals.
- the roller 31c contacts both the upper surface of the recess 27 and the lower surface of the turntable 30 to support the weight of the turntable 30 and food.
- An annular rib 30 a that surrounds the three rollers 31 c is formed on the lower surface of the turntable 30 so as not to be displaced with respect to the roller stay 31.
- the rotation is transmitted to the roller stay 31 through the rotation shaft 31d.
- the rotating shaft 31d is integrally formed with the hub 31a so as to hang from the hub 31a.
- the rotating shaft 31d passes through the rotating shaft insertion hole 26 vertically.
- the rotating shaft 31 d protruding from the bottom surface of the bottom wall of the heating chamber 20 is non-rotatably connected to the output shaft 32 a of the motor 32.
- the motor 32 is a shaft and is supported by the heating chamber 20 via a cup-shaped support base 33 fixed to the outer surface of the bottom wall of the heating chamber 20.
- the motor 32 incorporates a speed reduction mechanism and rotates the output shaft 32a at a reduced speed.
- a seal member 34 is disposed at a location where the output shaft 32 a passes through the support base 33 so that water does not leak from the support base 33 to the motor side.
- the upper end of the support base 33 is welded in close contact with the bottom wall of the heating chamber 20, and no gas or liquid leaks from here.
- the control elements of the high frequency cooking device 1 are shown in FIG.
- the control device 40 is responsible for overall control.
- the following components are connected to the control device 40. That is, a high-frequency drive power source 21 a that causes the high-frequency generator 21 to perform high-frequency oscillation, a temperature sensor 28 provided in the heating chamber 20, and a door opening / closing sensor 11 a provided for the door 11.
- the cooling fan 18, the LED 23, and the motor 32 are energized.
- the cooling fan 18 cools the heat generating components in the housing 10 by the air flow caused by the cooling fan 18.
- the LED 23 illuminates the inside of the heating chamber 20.
- the motor 32 rotates the output shaft 32 a, and the output shaft 32 a rotates the roller stay 31.
- a protrusion 50 is formed at a position on the bottom wall of the heating chamber 20 between the front opening of the heating chamber 20 and the roller stay 31, a person's hand is applied to the edge of the turntable 30. Even if the turntable 30 is tilted in this way, the turntable 30 hits the protrusion 50 before it is tilted so as to be disengaged from the roller stay 31, and no longer tilts. For this reason, when the force is released, the turntable 30 returns to the top of the roller stay 31 and rotates stably at that position. It is preferable to determine the height of the protrusion 50 by repeating experiments to determine how high the protrusion 50 is to be removed from the roller stay 31.
- the protrusion 51 may not be a continuous ring. There may be a configuration in which a plurality of short arc-shaped protrusions 51 or dot-shaped protrusions 51 are arranged at intervals.
