Description

Description: TECHNICAL FIELD The present invention relates to an electric heating cooker having a detachable plate.

2. Description of the Related Art In recent years, an electric heating cooker having a plate has been frequently used for baking cooking such as barbecue at home. The plate is generally detachable from the main body for convenience in cleaning and the like.

Hereinafter, this type of conventional cooker will be described with reference to FIG.

Reference numeral 1 denotes a cooking device main body having a heater 2 therein and a connection terminal 3 provided on a part of the peripheral wall, and a plate 4 is set removably above the cooking device main body.

A plug 5 that is detachably inserted into the connection terminal 3 and supplies power to the heater 2 has a built-in temperature controller (not shown) and a heat-sensitive rod 6 having a temperature sensor (not shown) therein. It protrudes and is provided.

When the plug 5 is connected to the connection terminal 3, the heat-sensitive bar 6 comes in contact with the bottom of the plate 4 and detects the temperature of the plate 4.

The temperature controller in the plug 5 controls the power supply to the heater 2 based on the temperature detection result, and operates so that the temperature of the plate 4 is maintained at a set value.

However, in the conventional configuration, the plug 5 for supplying electricity can be inserted even when the plate 4 is not mounted. At this time, the heat-sensitive rod 6 is exposed to the outside air, and the temperature controller is not operated. This is extremely dangerous because it may cause abnormal heating due to improper operation and damage to the body 1 due to heat or fire. Further, if the plate 4 is deformed by heat or the like, the contact of the heat-sensitive bar 6 becomes uncertain, so that the temperature cannot be detected accurately and the temperature of the plate 4 cannot be controlled correctly.

The present invention solves the above-mentioned conventional problems, and prevents abnormal heating by not energizing a heater when a plate is not mounted, and a heat-sensitive rod even when the plate slightly deforms due to heat or the like. The purpose was to ensure contact with the plate.

Means for Solving the Problems To achieve this object, a cooking device of the present invention has a main body having a heater and terminals at both ends of the heater facing plug connection terminals, and is detachably mounted on the main body. A plate for supplying current to the heater by inserting a temperature controller inside the plate and a heat-sensitive rod in contact with the plate, and inserting the plug into a terminal for plug connection. When the plate is mounted, the heat-sensitive bar is pushed up and pressed against the bottom surface of the plate. When the plate is not bonded, a shield plate is provided to block the heat-sensitive rod insertion path.

Operation With this configuration, when the plate is not mounted, the heat-sensitive rod insertion path is blocked by the shield plate. Therefore, a power supply plug cannot be connected. When the plate is mounted, the shielding plate pushes up the heat-sensitive bar and presses it against the bottom surface of the plate.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 to 4, reference numeral 7 denotes a plate on which the food is placed for cooking, which can be detachably attached to the cooking device body 8.
9 is a heater for heating the plate 7. This heater 9
Are connected to terminals 11 provided on a part of the peripheral wall of the cooking device main body 8. The terminal 11 is provided with an insertion hole 12. The power supply to the heater 9 is performed by connecting a power supply plug 14 having a heat-sensitive rod 13 at the tip and having a built-in temperature controller (not shown). I do. or,
At this time, the heat-sensitive rod 13 contacts the plate 7 while penetrating the insertion hole 12 and fitting into the inverted U-shaped projection 15 provided on the bottom surface of the plate 7 to detect the temperature. The tip has an acute angle. Reference numeral 16 denotes a substantially L-shaped elastic shielding plate made of a spring material. One end is fixed to a heat shielding plate 17 inside the main body, and the free end passes through the heat shielding plate 17 and faces the plate direction.

The operation of the cooker configured as described above will be described below.

When the plate 7 is not mounted on the cooker main body 8, the shielding plate 16 blocks the insertion path of the heat-sensitive bar 13 due to its elasticity as shown in FIG. 3, and the plug 14 cannot be connected. Therefore, power cannot be supplied to the heater 9.

When the plate 7 is mounted on the cooker main body 8, the shielding plate 15 is pushed down by an inverted U-shaped projection 16 provided on the bottom surface of the plate. If the height of the projections 19 is smaller than the diameter of the heat-sensitive bar 13 as shown in FIG. 4, a part of the insertion path of the heat-sensitive bar 13 will be blocked even when the plate 7 is mounted. Since the tip of the rod 13 is at an acute angle, it can be inserted so as to pry open the shielding plate 16. The inserted heat-sensitive bar 13 is always subjected to a force in the plate direction by the shield plate 16 and maintains a good contact state.

As described above, according to the present embodiment, the shield plate is urged toward the plate by the cooker main body 8, moves up and down in response to the attachment and detachment of the plate, and pushes up the heat-sensitive bar 13 when the plate is attached to the bottom surface of the plate. By providing the plate 16, when the plate 7 is not mounted, the shielding plate 16 blocks the heat-sensitive rod insertion path due to the urging force in the plate direction, and the plug 14 cannot be connected. As a result, the heater 9 is not energized, and damage to the cooking device body 8 due to abnormal heating, a fire, and the like can be prevented. When the plate is mounted, the shield plate 16 is pushed down by the inverted U-shaped projection 15 on the bottom surface of the plate, so that the heat-sensitive rod 13 can be inserted and the heater 9 is energized. At this time, since the height of the inverted U-shaped projection is smaller than the diameter of the heat-sensitive bar 13, the heat-sensitive bar 13 is always urged to the plate bottom surface by the elastic shielding plate 16, and the plate 7 is slightly deformed by heat or the like. Also pressed. Therefore, the accuracy of detecting the temperature of the heat-sensitive bar 13 is improved, and the temperature control of the plate 7 becomes more accurate.

If the height of the inverted U-shaped protrusion 15 on the bottom of the plate is smaller than the diameter of the heat-sensitive bar 13 only at the portion that contacts the elastic shielding plate 15 and the other portions are larger than the diameter, most of the heat-sensitive bar 13 It is covered with an inverted U-shaped projection 15. This makes the heat-sensitive bar 13 less susceptible to changes in the outside air temperature and the flow of air, and the temperature detection becomes more accurate.

Also, as shown in FIG. 5, it goes without saying that the same effect can be obtained even when the shielding plate 20 is urged upward by a separately provided spring 19 instead of the substantially L-shaped elastic plate 13.

Effect of the Invention As described above, the cooking device of the present invention is configured such that the cooking device main body is urged in the plate direction by an elastic body, moves up and down in response to the attachment and detachment of the plate, and pushes up the heat-sensitive bar when the plate is attached to the bottom of the plate. When a plate is not mounted, a shield plate is provided to block the heat-sensitive rod insertion path.When the plate is not mounted, the heat-sensitive rod insertion path is blocked by the shield plate and plugs cannot be connected, so the heater is energized. In addition, damage to the main body and fire due to abnormal heating can be prevented beforehand, and safety can be greatly improved.
In addition, when the plate is mounted, the heat-sensitive bar is urged in the plate direction by the shield plate, so that even if the plate is slightly deformed by heat or the like, the press-contact state can be favorably maintained. Therefore, the accuracy of temperature detection by the heat-sensitive bar is improved, and the temperature control of the plate becomes more accurate.
