FIG. 1 is a longitudinal sectional view of the entire hot plate, and FIG. 2 is an exploded perspective view of a plate, a tray, an intake box, and a heat shield plate which constitute a main part of the hot plate of FIG. The hot plate shown in FIGS. 1 and 2 has a plate 1 heated by a heater 8 disposed above a heat shield plate 11 fixed inside a main body case 10, and through holes 2 and 2 formed in the plate 1. By doing so, the gravy or oil is discharged to the tray 3 provided on the back surface of the plate 1 so that grilled meat or the like can be cooked in a state where oil does not accumulate.

Below the plate 1, an intake box 6 is arranged on a heat shield plate 11. The upper halves of the left and right side surfaces of the intake box 6 are formed as chamfered inclined surfaces, which are used as catalyst intake surfaces 7. The catalyst intake surface 7 is formed in a window shape, and the oxidation catalyst 5 formed in a honeycomb shape or another air-permeable state is disposed on the entire surface thereof. At this time, the size and arrangement of the ventilation box 6 are set so that the heater 8 for heating the plate 1 is located immediately above the catalyst intake surface 7 formed on the inclined surface.

A relatively large ventilation hole 12 is formed in the heat shield plate 11 at a position where the intake box 6 is arranged. In addition, a fan 13 is mounted in a space between the heat shield plate 11 and the main body case 10, and the air in the intake box 6 is passed through the ventilation holes 12 to evacuate the main body case
The space between the heat shield 10 and the heat shield plate 11 can be sucked. Further, the tray 3 provided on the back surface of the through hole 2 portion of the plate 1 is detachably attached to the plate 1 by forcible fitting, spring fitting or any other means, and is provided as a vent hole in the side wall 3a facing the vent box 6. 2, a large number of circular through holes 4 are formed.

As a result, the catalyst suction surface 7 passes through the through hole 2 of the plate 1 to the tray 3 and from the through hole 4 of the tray 3 to the tray 3.
, A ventilation path is formed from the suction box 6 to the ventilation hole 12 of the heat shield plate 11 and the space between the heat shield plate 11 and the main body case 10 to the outside of the device. Therefore, by sucking the air in the suction box by a fan or other suction means provided between the heat shield plate 11 and the main body case 10, the smoke on the upper surface of the plate 1 passes through the air passage, and the oxidation catalyst 5 and is discharged out of the vessel in a clean state.

The type and operating temperature of the oxidation catalyst 5 used in the present invention are not limited, as long as it promotes at least oxidation through the passage of smoke. However, oxidation catalysts such as platinum, which are usually used, exhibit their functions sufficiently at high temperatures. The temperature is preferably used at a high temperature of 350 degrees Celsius or more in the case of oil smoke.

In the embodiment shown in FIGS. 1 and 2 of the present invention,
An intake box 6 is arranged below the plate, and an oxidation catalyst 5 is arranged on a catalyst intake surface 7 formed as an inclined surface in a part of the intake box. Then, the size, shape, and arrangement position of the intake box are selected so that the oxidation catalyst 5 is located immediately below the heater 8 for heating the plate 1. Therefore, the oxidation catalyst is easily heated by the heat of the heater 8. Also,
A catalyst heater 9 is separately provided inside the intake box 6 for heating the oxidation catalyst 5. As a result, the oxidation catalyst 5 is heated to a higher temperature, and the action of purifying the smoke is promoted.

By attaching 15, the unit can be attached to and detached from the body case separately from the plate. In other words, the plate 1 can be attached to and detached from the main body case with the handle 15 in a state where the plate 1 is placed on the tray 3, and the high-temperature plate after cooking can be attached and detached together. is there.

On the heat shield plate 11, an intake box 6 formed in a substantially rectangular parallelepiped in the drawing is arranged. The width of the intake box 6 is
The clearance between the two receiving pans 3 ', 3', that is, the distance between the opposing inner side walls 3a, 3a, is substantially equal to that of the receiving pans 3 ', 3'. It is designed to be mounted in a state. The inner side wall 3a of the two trays 3 ', 3' has a notch 3b formed in the upper half thereof, and the upper half of the side wall of the intake box 6 serves as a catalyst intake surface 7.

With the above configuration, in a use state where the tray 3 and the plate 1 are mounted on the main body case,
Since the tray 3 and the suction box 6 are mounted without any gap, and the catalyst suction surface 7 of the suction box 6 faces the cutout 3b of the tray 3 ', a ventilation path indicated by an arrow is formed. In the embodiment shown in FIGS. 3 and 4, the suction box 6 arranged on the heat shield plate 11 serves as a guide when attaching and detaching the tray. Further, since the ventilation path is formed in a state where the two receiving trays 3 ', 3' and the suction box 6 are mounted without any gap, the smoke on the upper surface of the plate can be effectively sucked without sucking extra air. . Of course, the intake box 6 provided on the heat shield plate 1 may have an upper surface of the side wall formed as an inclined surface as shown in FIGS. A catalyst heating heater 9 for heating the oxidation catalyst 5 is provided in the box of the intake box 6.
