Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a hot plate that can be heated entirely or locally.

[Conventional technology]

The heater that heats the plate is fixed to the upper surface of the exterior body on which the plate is placed, and cooks the food on the plate by heating the entire surface of the plate almost uniformly.

[The problem that the idea attempts to solve]

The entire surface of the plate is heated evenly and the cooking temperature is almost the same, so you can use the entire surface of the plate to cook food, but you can cook food using one part of the plate while cooking the food. When trying to keep food warm by using other parts of the plate to prevent it from cooling down, there was a problem in that the food being kept warm would become overheated.

Furthermore, when the amount of food to be cooked is small, it may be desirable to heat only a partial area of the plate for the purpose of saving electricity.

The present invention aims to solve this problem, and it is a hot plate that can heat the entire surface of the plate, or use a part of the plate as a cooking area and the other part as a heat-retaining area. It provides plates.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a hot plate that heats a plate placed on an exterior body with a heater, in which the heater is divided into a first heater whose position is fixed and a second heater which is movably provided. The first heater and the second heater heat the entire surface of the plate or locally heat the plate.

[Effect]

In the hot plate configured as described above, the position of the heating area of the plate can be changed by moving the movable second heater, so if the second heater is moved away from the first heater, the position of the heating area of the plate can be changed. The entire surface can be heated to a substantially uniform cooking temperature, and when the second heater is brought close to the first heater, a part of the plate can be locally heated to the cooking temperature.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a longitudinal sectional view of the hot plate A, and FIG. 2 is a plan view of the exterior body 1 of the hot plate A.

The exterior body 1 has a top plate 2 fixed to the top surface, and a first arc-shaped heater 4 is fixed to a heater support 3 provided on the top surface of the top plate 2 by a fastening band or the like.

A support shaft 5 is fixed to the center of the inner bottom surface of the exterior body 1,
A rotary table 6 is rotatably fitted onto the outer peripheral surface of the support shaft 5.

A flange portion 7 is provided around the upper end of the rotary table 6,
An arcuate second heater 8 is fastened to the upper surface of the flange portion 7 with a fastening band or the like, and a gear 9 is provided at the bottom of the rotary table 6.

An annular support stand 10 is fixed to the exterior body 1 in the vicinity of the flange portion 7, and power supply rings 11a, 11b are inserted into two annular grooves provided on the upper surface of the support stand 10.
are fixed, and current collection brushes 12a and 12b provided at both ends of the second heater 8 are slidably in contact with power supply rings 11a and 11b, respectively.

Power supply rings 11a, 11b and first heater 4
Both ends thereof are electrically connected to a temperature regulator 13 provided in the exterior body 1 and having a thermostat installed therein via conductive wires.

A shaft 15 having a male thread is screwed into a screw hole of a bearing 14 provided on the inner bottom surface of the exterior body 1, and a lever 16 is pivotally connected to the shaft 15.

The lever 16 has an operating handle portion 16a projecting from the exterior body 1 on one side, and a sector gear 17 that meshes with the gear 9 on the other side.

Therefore, when the operation handle portion 16a is manually operated, a manual device is configured to rotate the rotary table 6 via the sector gear 17 and the gear 9.

The plate 18 that is detachably placed on the exterior body 1 has protrusions 19 and 20 protruding from its outer bottom surface to cover both sides of the first heater 4 and the second heater 8, and is placed on the first heater 4. The food inside is heated by the first heater 4 and second heater 8 to cook the food inside.

The protrusions 19 and 20 described above may be provided on the exterior body 1 instead of on the plate 18.

The operation of the hot plate A constructed as above will be explained.

Turn the operating handle 16a of the lever 16 to release the rotatable arc-shaped second heater 8 as shown in FIG.
When the plate 18 is rotated to a position away from the fixed arc-shaped first heater 4 and the temperature regulator 13 is energized, the entire surface of the plate 18 is heated almost uniformly.

Therefore, the entire surface of the plate 18 can be used for cooking.

When the lever 16 is rotated and the gear 9 and rotating table 6 are rotated approximately 180 degrees via the sector gear 17, the second heater 8 approaches the center of the first heater 4, so that the plate 18 is connected to the first heater. 4 is heated locally on the central side, and not so much on the opposite side.

Therefore, while cooking is performed on the local heating side, the cooked food can be kept warm on the opposite side without overheating.

3 and 4 are a longitudinal sectional view of a hot plate _A1 and a plan view of an exterior body of the hot plate _A1 , showing another embodiment.

The exterior body 1 has an upper plate 2 fixed to the upper surface, and a substantially U-shaped first heater 21 is fixed to the upper surface of the upper plate 2 by a fastening band or the like.

A sliding base 22 having a sliding groove on the upper surface is fixed to the inner bottom surface of the exterior body 1, and a moving base 23 is movably inserted into the sliding groove of the sliding base 22.

A flange portion 24 is provided at the upper end of the movable table 23, and a small second heater 25 is fastened to the upper surface of the flange portion 24 with a fastening band or the like, and the movable table 2
A rack 26 is provided at the bottom of 3.

A support stand 27 close to the flange portion 24 is fixed to the exterior body 1, and power feeders 28a and 28b are fixed to two grooves provided on the upper surface of the support stand 27.
Current collector brushes 29a and 29b provided at both ends of the second heater 25 are connected to power feeders 28a and 28, respectively.
slidingly contacts b.

Both ends of the power supply bodies 28a, 28b and the first heater 21 are electrically connected via conductive wires to a temperature regulator 13 provided in the exterior body 1 and having a thermostat installed therein.

A shaft 15 having a male thread is screwed into a screw hole of a bearing 14 provided on the inner bottom surface of the exterior body 1, and a lever 16 is pivotally connected to the shaft 15.

The lever 16 has an operating handle portion 16a projecting from the exterior body 1 on one side, and a sector gear 17 that meshes with the rack 26 on the other side.

Therefore, when the operation handle portion 16a is operated, a manual device is constructed that moves the movable table 23 via the sector gear 17 and the rack 26.

A plate 18 that is detachably placed on the exterior body 1 is placed on a first heater 21 and is heated by the first heater 21 and second heater 25 to cook the food inside. .

The hot plate _A1 of the second embodiment configured as described above can be moved to the movable table 2 by operating the lever 16.
3 to change the position of the second heater 25, the entire surface of the plate 18 or local heating can be performed as in the first embodiment.

[Effect of idea]

Since the present invention is configured as described above, it is possible to heat the entire surface of the plate almost evenly for cooking, or to locally heat one area of the plate for cooking while cooking already cooked food in other areas. It can also be kept warm, which can be switched by simply turning a lever.
