Description

[Detailed description of the invention] <<Industrial Application Field>> This invention relates to an electric heating pot for tea ceremony, which is used for boiling water during tea making.

<<Prior Art>> As shown in FIG. 6, a kettle body 40 used in tea ceremony with an electric heating device body 41 attached thereto is known.

Also, as shown in FIG. 7, a sheathed heater 50
A heating plate 52 is welded to a metal plate 51, and a cooking container 5 is attached to a plurality of mounting holes 53 formed in the metal plate 51.
A cooking device is known in which the cooking container 54 is press-fitted to the bottom surface by fitting a bolt 55 set up on the bottom surface of the container 4 and tightening it with a nut 56 (see Japanese Utility Model Publication No. 36-3849).

<<Problems to be solved by the invention>> By the way, what is shown in Fig. 6 is the pot body 40.
Since the electric heating device body 41 is attached so that it cannot be easily removed by an amateur, when cleaning the inside of the pot body 40 or cleaning the outside of the pot body 40, care must be taken to prevent cleaning water from splashing onto the electric heating device body 41. Moreover, it is extremely inconvenient, and it also has the disadvantage that it cannot be used when charcoal is used as the heat source.

In addition, in the case shown in FIG. 7, a tool for rotating the nut 56 must be used to remove the nut 56 screwed into the bolt 55, which requires a complicated operation and causes damage to the inside of the cooking container 54. The heating plate 52 cannot be removed with hot water still in it, and the cooking container 54 has a thin bottom plate so that cooking can be done using charcoal, which is a heat source other than electricity. Since the heat source was not designed as a heat source, it had the disadvantage that it could not be used when using charcoal as the heat source.

This invention solves the above-mentioned problems, and aims to provide an electric heating pot for tea ceremonies that is easy to handle and can also be used as a heat source during tea ceremonies, such as charcoal.

<Means for Solving the Problems> In order to achieve the above object, the electric heating pot for tea ceremonies of this invention is provided with a pot lid 1 and a pot body 3 having a disc-shaped bottom plate 2, which is mounted on an electric heating device body 4. In the removably mounted electric heating device body 4, a frame body 10 having a mounting top plate 9 on which a disc-shaped bottom plate 2 is placed is provided, and a frame body 10 is provided at the center of the mounting top plate 9. A heat-generating disc body 6 is provided in the central hole 25 to abut the central flat part 5 of the disc-shaped bottom plate 2, and at least three protruding leg parts 7, 7, 7 are provided on the periphery of the disc-shaped bottom plate 2 to protrude downward. Locking portions 8, 8, 8 for removably locking the protruding leg portions 7, 7, 7 are provided on the mounting upper plate 9, and the protruding leg portions 7, 7, 7 and the locking portions 8, 8, 8 is formed so that it can be attached and detached only by rotation of the hook body 3, and when the protruding legs 7, 7, 7 and the locking parts 8, 8, 8 are engaged, the periphery of the disc-shaped bottom plate 2 is attached. In the provided locking groove 22,
The elastic plate 24 provided with the fingertip pressing part 23 provided on the electric heating device body 4 is locked, and the elastic plate 24 is formed so as to be released from the locking groove 22 when the fingertip pressing part 23 is pressed.

<<Embodiment>> An embodiment of this invention will be described below with reference to the drawings. 1 is a pot lid of a pot body 3, and a disc-shaped bottom plate 2.
The pot body 3 having the above-mentioned structure is detachably placed on the electric heating device body 4, and the electric heating device body 4 further includes a frame body 10 having a mounting plate 9 on which the disc-shaped bottom plate 2 is placed. It was established.

In addition, in the center hole 25 provided in the center of the upper mounting plate 9,
A heat-generating disk body 6 is provided which comes into contact with the central flat part 5 of the disk-shaped bottom plate 2, and three or more protruding legs 7, 7, 7 are provided on the periphery of the disk-shaped bottom plate 2 and protrude downward, and the protruding legs 7 are provided. , 7, 7 are provided on the upper mounting plate 9, and the protruding leg parts 7, 7, 7 and the locking parts 8, 8, 8 are attached to the hook main body 3. It is formed so that it can be attached and detached only by rotation.

In addition, when the protruding leg parts 7, 7, 7 and the locking parts 8, 8, 8 are locked, the locking groove 2 provided on the periphery of the disc-shaped bottom plate 2 is used.
An elastic plate 24 provided with a fingertip pressing part 23 provided on the electric heating device body 4 is locked to the fingertip pressing part 2, and the elastic plate 24 is attached to the fingertip pressing part 2.
If the elastic plate 24 is not removed from the locking groove 22 by pushing down the hook 3, the hook body 3 will not rotate and the protruding legs 7, 7, 7 will not rotate.
This is to prevent the locking parts 8, 8, 8 from coming apart.

Further, a heat insulating cylinder 12 is provided on the inner peripheral edge 11 of the central hole 25 provided in the center of the upper mounting plate 9.
The heat shield cylinder 14 is connected to the piece 15 through the gap 13,
15, 15, 15, and a heating element support fitting 18 is provided, in which the heating disk body 6 is attached via the mounting piece 16 and the tightening nut 17, and the heating element support fitting 18 is connected to the bottom cover 19. It is installed by tightening bolts and nuts 20 with a heat shield cylinder 14 interposed between them.

Further, a heat insulating plate 21 is attached to the upper mounting plate 9.

In addition, an overheating prevention switch body 26 that contacts the disc-shaped bottom plate 2 of the pot body 3 is exposed through an exposure port 27 on the upper mounting plate 9, so that the power supply to the heat-generating disc body 6 is automatically stopped in the event of overheating. It is something. Furthermore, the electric heating device body 4 is equipped with a safety switch 28 that detects abnormal overheating and automatically stops the electricity supply.

Further, 29 is a magnetic socket, and 30 is a socket socket. Furthermore, if a controller 32 is used in the middle of a cord 31 connected with a magnetic socket 29, temperature adjustment is also possible.

In addition, the illustrated protruding leg portions 7, 7, 7 and the locking portion 8,
8, 8, the protrusion legs 7, 7, 7 are formed with L-shaped protrusions, and the locking parts 8, 8, 8 are formed with L-shaped holes, which allow the hook body 3 to rotate. Therefore, the pot body 3 and the electric heater body 4 can be attached and detached.

《Operations and Effects of the Invention〉 This invention has the above-mentioned configuration, and includes a kettle body 3 having a pot lid 1 and a disc-shaped bottom plate 2, which is removably mounted on an electric heating device body 4. The electric heating device body 4 has a placement top plate 9 on which the disc-shaped bottom plate 2 is placed.
By providing a frame body 10 with It is sometimes suitable for use as a pot for hearths, and after arranging the charcoal with simulated charcoal, this tea ceremony electric pot can be placed on a trivet and energized to boil water.

Further, three or more projecting legs 7, 7, 7 are provided on the peripheral edge of the disc-shaped bottom plate 2, and the projecting legs 7,
