DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. First, referring to FIGS. 4 and 5, the main body 11 includes a main body case 12 whose upper surface is open.
And a front flange portion 13, a rear flange portion 14, and top plate retainers 15 and 16 which form the peripheral edge of the main body case 12, respectively. The top plate retainers 15 and 16 are arranged on the left and right receiving portions 12a and 12b formed on the main body case 12 (details will be described later).
16 upper surface, front flange portion 13 and rear flange portion 1
The heights of the upper surfaces of 4 are substantially the same.

A heat insulating plate 17 is arranged at the bottom of the main body 11, and a unit mounting plate 19 is attached to the heat insulating plate 17 via a compression spring 18. And
A heater unit 22 having halogen lamp heaters 20, 20 serving as heating means and a temperature sensing portion 21 serving as temperature detecting means is mounted on the mounting plate 19. Further, a heat-resistant glass top plate 23 is attached to the upper portion of the heater unit 22 via an attachment plate 24. In this case, the mounting plate 24 holds the peripheral portion of the top plate 23. Then, the heater unit 22 and the top plate 23 are integrated and are always urged to move upward by the compression spring 18, and the top plate retainers 15 and 16 are engaged with the engaging step portions 15a and 16a formed inside thereof. Holds the upper surfaces of the left and right edges of the top plate 23.

By the way, the above-mentioned top plate 23 is constructed so as to be able to float above the front flange portion 13, the rear flange portion 14 and the top plate retainers 15 and 16 which are peripheral portions of the top plate 23 in the main body 11, in other words. For example, the front flange portion 13, the rear flange portion 14 and the top plate retainers 15 and 16 are relatively arranged on the top plate 23.
The structure is lower than the top surface. The structure will be described on behalf of the right top plate retainer 16 portion.

As shown in FIG. 1, the top plate retainer 1
6 is provided on the receiving portion 12b so as to be slidable in the left-right direction, and a release pin 25 is vertically provided on the top plate retainer 16. The release pin 25 is inserted through a long groove portion 26 formed in the receiving portion 12b and projects downward. An insertion opening 27 is formed in a side portion of the main body case 12, and a floating stopper 28 is movably provided in the insertion opening 27. An engagement recess 29 is formed on the upper surface of the floating stopper 28, and a stopper portion 30 and a descending lock groove portion 31 are formed at the tip. The floating stopper 28 is constantly urged to move in the direction of arrow A by a spring 32.

Further, the engaging recess 2 of the floating stopper 28
A lock lever 33 is rotatably supported by an upper portion of the shaft 9 through a mounting tool (not shown), and is constantly urged in the direction of arrow B by a torsion spring 34. The lock lever 33 is provided on the lower surface of the receiving portion 12b.
Is formed with a stopper 35.

Further, a lock plate 36 having a lock portion 36a formed on the lower portion is attached to the mounting plate 24 which holds the top plate 23. The left top plate retainer 15 portion has the same structure.

On the other hand, as shown in FIG. 5, a limit switch 37 is provided above the left side levitation stopper 28, and the actuator 37a thereof has a limit switch 37a.
8 is opposed to the lock portion 36a of the lock plate 36, and the limit switch 37 constitutes an energization control means together with the control portion 38, as shown in FIG.
When the actuator 37a is actuated by the lock portion 36a and turned on, an on signal, that is, a flying detection signal is output and given to the control portion 38, and the control portion 38 controls the drive circuit 39 having a triac to control the halogen lamp heater. It is configured such that the energization path to 20 is opened, that is, energization to the halogen lamp heater 20 is prohibited.

Further, as shown in FIG. 7, an electromagnetic solenoid 40 as a locking means is provided inside the main body 11, and a plunger 40a of the electromagnetic solenoid 40 is inserted into an insertion hole 12c formed in the receiving portion 12b. When the temperature detected by the temperature sensing section 21 as the temperature detecting means for detecting the temperature of the top plate 23 is equal to or higher than a predetermined temperature,
The controller 40 is energized via the drive circuit 41 to insert and engage the plunger 40a into the lock hole 16b formed in the top plate retainer 16.

As shown in FIG. 4, on the front flange portion 13 of the main body 11, a power source “ON” switch 42, a power source “OFF” switch 43, and heating intensity setting switches 44, 45.
Is provided.

Now, the operation of the above configuration will be described.
The states shown in FIGS. 1 and 5 are normal states. In this state, the limit switch 37 does not output an ON signal, and therefore the halogen lamp heater 20 is not in the energization prohibited state. Then, in the case of performing heating and cooking, when a heating container such as a pot is placed on the top plate 23 and the power “ON” switch 42 is turned on, the control unit 38
Energizes the halogen lamp heater 20 via the drive circuit 39. As a result, the halogen lamp heater 20 generates heat and radiates heat, thereby heating the heating container.

Next, when cleaning the top surface of the top plate 20, the top plate retainers 15 and 16 are slid in the outward direction (directions of arrow C and arrow A in FIG. 5, respectively). Since the operation and operation of each part on the top plate 15 side are the same as the operation and operation of each part on the top plate 16 side, the operation and operation of the top plate 16 side will be described below as a representative.

However, in a situation where the temperature of the top plate 23 is not so high, the control section 38 turns off the electromagnetic solenoid 40, so that the plunger 40a thereof is
The lock hole 16b is not inserted (the state shown in FIG. 7). Well, top plate retainer 16
When the slide plate is operated, the pressing action on the top plate 20 by the engagement step portion 16a of the top plate presser 16 is released, and the top plate 20 and the heater unit 2 are released.
2 is moved upward by the spring force of the spring 18. At this time, the lock portion 36a of the lock plate 36 is moved to the floating stopper 28
The upper limit position of the top plate 20 is regulated by contacting the stopper portion 30 of the above. This state is shown in FIG.

From this state, the floating stopper 28 is attached to the spring 3
Push in the direction opposite to arrow A against the spring force of 2.
Then, as shown in FIG. 3, the descending lock groove portion 31 of the levitation stopper 28 is fitted into the lock portion 36a of the lock plate 36 to regulate the vertical movement of the lock plate 36, and the lock lever 33 twists the torsion spring. The spring force of 34 fits into and engages the engaging recess 29 of the floating stopper 28 to prevent the floating stopper 28 from returning in the direction of arrow A. In this case, further rotation of the lock lever 33 in the arrow B direction is restricted by the stopper 35.

On the other hand, due to the floating of the top plate 23,
As shown in FIG. 6, the limit switch 37 is actuated by the lock portion 36a on the left side to be turned on.
As described above, energization of the halogen lamp heater 20 is prohibited.

In this way, the top plate 23 is
The top plate retainers 15 and 16 which are a part of the periphery of the top plate 23 of the main body 11 are floated up, and the top plate retainers 15 and 16 are relatively lower than the top surface of the top plate 23. Thereafter, as shown in FIG. 5, the scraper S is scraped in the direction of the top plate retainer 15 or the top plate retainer 16 to scrape the food dust on the upper surface of the top plate 23, and the top plate retainers 15, 16 ( It is excluded from a portion lower than the upper surface of the top plate 23).

Thereafter, to return to the original state, the top plate retainer 16 (15) is further slid outward from the state shown in FIG. Then, the lock pin 33 is rotated in the direction opposite to the arrow B by the release pin 25, and the engaging recess 29
Is disengaged. As a result, the levitation stopper 28 is returned in the direction of arrow A by the spring force of the spring 32, and the lock portion 36a of the lock plate 36 is relatively pulled out from the descending lock groove portion 31. As a result, the top plate 23 can be moved downward, the top plate 23 is pushed downward, the top plate retainer 16 (15) is slid inward, and the top of the engagement step 16a (15a) is used. The upper surfaces of the left and right edges of the plate 23 are pressed (see FIG. 1).

Further, when the temperature of the top plate 23 is high, the temperature detected by the rod 21 becomes a predetermined temperature or higher, and as a result, the control unit 38 causes the electromagnetic solenoid 40 to move.
And the plunger 40a is inserted into and engaged with the lock hole portion 16b. As a result, the slide operation of the top plate retainer 16 (15) is prevented, in other words, the top plate 23 does not float, that is, the top plate retainer 16 (15) of the main body 11 does not lower relatively. Locked.

As described above, according to this embodiment, by moving the top plate 23 upward, the top plate retainers 15 and 16 can be made lower than the top surface of the top plate 23, so that the food dust on the top plate 23 is removed. It can be easily removed to the outside of the top plate 23, and the cleanability can be improved.

Further, according to the present embodiment, the limit switch for detecting that the top plate 23 has moved upward, in other words, that the top plate retainers 15 and 16 are relatively lower than the top surface of the top plate 23. Since the limit lamp 37 is provided and the detection operation of the limit switch 37 is performed to prohibit the energization of the halogen lamp heater 20,
When the top plate 23 is easily touched by the hand, the halogen lamp heater 23 is safe because it is not energized.

Further, according to the present embodiment, when the temperature detected by the temperature sensing section 21 which is the temperature detecting means exceeds a predetermined temperature, the electromagnetic solenoid 40 is operated to prevent the top plate retainer 16 (15) from floating. So, in other words,
Since the top plate retainer 16 (15) is locked so as not to lower relatively, the top plate 23
If the top plate 23 is hot, the top plate 23 can be prevented from rising and it is safe.
