Abstract

PURPOSE:To permit the electric conduction by installing a safety plate which operates in correspondence with the placement of a plate and connecting a connection terminal and an electrical connecting plug only in the case when the plate is correctly placed. CONSTITUTION:One edge of a nearly L-figure shaped safety plate 15 made of elastic material is fixed on a heat shielding case, and the free edge extends toward a plate 10 and is vertically moved in correspondence with the mounting/ demounting of the plate 10. When the plate 10 is correctly placed, the opposed space of the insertion hole 14 of the safety plate 15 is opened by a projection part 17 on the reverse surface, and a heat sensing rod 12 is advanced and a connection terminal 9 and an electrical connecting plug 11 can be set. Since, when the plate 10 is not placed or not correctly placed, the opposed space of the insertion hole 14 formed in the connection terminal 9 is closed by the safety plate 15, the heat sensitive rod 12 can not be inserted before it is inserted into the insertion hole 14 and contacts the plate 10. Accordingly, when the plate 10 is not placed or not correctly placed on a cooker body, the electric conduction for a heat generating body is disabled, and the trouble of the generation of fire diaster due to the erroneous use can be prevented beforehand.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking device having a removable plate.

BACKGROUND OF THE INVENTION In recent years, heating cookers with plates have been easily used at home for various grilled dishes. The plates are also removable for easy cleaning after cooking.

A conventional cooking device will be explained below using figures.

In the conventional cooker shown in Fig. 10, 1 has a heating element 2 inside.
The main body of the cooking device has a connection terminal 3 provided on a part of the peripheral wall, and a plate 4 is detachably set above the main body of the cooking device.

The heating element 2 is removably inserted into the connection terminal 3 above.
The electrical connection plug 6 for supplying power to the device is provided with a heat-sensitive rod 6 projecting forward and having a built-in temperature regulator (not shown) and a temperature sensor (not shown) inside.

This heat-sensitive rod 6 is connected to the electrical connection plug 6 at the connection terminal 3.
When connected, it comes into contact with the bottom of the plate 4 and detects the temperature of the plate 4.

The temperature regulator in the electrical connection plug 6 controls the amount of electricity supplied to the heating element 2 based on the temperature detection result of the heat-sensitive rod 6.
It operates so that the temperature of the plate 4 is maintained at a set value.

Problems to be Solved by the Invention However, in the above configuration, even if the plate 4 is forgotten to be placed or is not placed correctly, the heating element 2 is energized. At this time, since the heat-sensitive rod 6 is not in contact with the plate 4 or is not in reliable contact with the plate 4, the electricity is continuously supplied to the heating element 2. Therefore, the cooker body 1 overheats, and the heat is transmitted to the bottom, resulting in a high temperature state that may burn the table or cause a fire if flammable materials such as paper or cloth are placed on the heating element 2. It had some drawbacks.

The present invention solves the above-mentioned conventional problems. By providing a safety plate that responds to the placement of the plate, the connection terminal and the electrical connection plug are allowed to connect only when the plate is placed correctly. The purpose is to provide a cooking device with established safety that enables the following.

Means for Solving the Problems To achieve this object, the cooking appliance of the present invention is provided with a plate-responsive safety plate in the insertion path of the electrical connection plug.

Effect: With this configuration, when the plate is correctly placed on the cooker body, the safety plate opens the insertion path for the electrical connection plug and allows connection of this electrical connection plug to the connection terminal. .

In addition, if the plate is forgotten to be placed or is not placed correctly, the safety plate is located in the insertion path of the electrical connection plug. Therefore, the electrical connection plug cannot be connected to the connection terminal, and it becomes impossible to supply electricity to the heating element.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

In Figures 1, 2, and 3, 7 indicates a heating element 8 inside.
The cooking device body has a connection terminal 9 provided in a part of a heat shielding case 16, and a plate 10 can be detachably attached above the cooking device body.

The heating element 8 is detachably connected to the connection terminal 9 above.
The electrical connection plug 13 that supplies power to the temperature regulator (
A heat-sensitive rod 12 having a built-in temperature sensor (not shown) is provided so as to protrude forward.

The connection terminal 9 has a terminal portion 13 which receives power from the electrical connection plug 11 and transmits it to the heating element 8, and an insertion hole 14 into which the heat-sensitive rod 12 is inserted.

Reference numeral 16 denotes an abbreviated safety plate made of an elastic member, one end of which is fixed to the heat shield case 16, and a free end extending toward the plate 10. In response to the attachment and detachment of the plate 10, it moves up and down to open and close the space facing the insertion hole 14. That is, when the play 10 is placed, the free end of the safety plate 16 is pushed down by the convex portion 17 protruding from the bottom surface of the play, thereby opening the opposing space.

The operation of the cooking device configured as described above will be explained below.

FIG. 4 shows that if the plate is forgotten to be placed or is not placed correctly, the space facing the insertion hole 14 provided in the connection terminal 9 is closed by the safety plate 16, so the heat-sensitive rod 12 It cannot be inserted through the insertion hole 14 until it touches the hole 10.

Therefore, the terminal portion 13 in the connection terminal 9 and the electrical connection plug 11 cannot be connected, and electricity cannot be applied.

FIG. 5 shows a case where the plate 10 is placed correctly.
Since the free end of the safety plate 16 is pushed down by the protrusion 17 provided on the back surface of the plate 10, the safety plate 16 moves downward and the space opposite the insertion hole 14 is opened. Therefore, the heat-sensitive rod 12 enters through the insertion hole 14, and the connection terminal 9 and the electrical connection plug 11 can be set. At this time, the heat-sensitive rod 12 comes into contact with the plate 1o and detects the temperature of the plate 10. Then, the result is sent as an electric signal to a temperature controller (not shown) in the electrical connection plug 11, and the electric current is adjusted by comparing it with a set temperature. The current is transmitted to the heating element 8 from the terminal portion 13 within the connection terminal 9.

As described above, according to this embodiment, by providing the abbreviated safety plate 16 made of an elastic member that responds to the suppression of the plate 10 when the plate 10 is placed on the cooking device main body 7, Can prevent incorrect use.

Next, FIGS. 6 and 7 show a second embodiment of the present invention. That is, in the first embodiment, the safety plate 15 was an abbreviated shape made of an elastic member, but in this embodiment, a rectangular safety plate 18 is provided so as to be movable up and down by a spring 19, and is attached upwardly by the spring 19. It is something that has been strengthened.

In this configuration, when the play plate 10 is set correctly, the safety plate 15 is pushed down by the protrusion 17 of the play plate 10 against the spring 19, the space facing the insertion hole 14 is opened, and the heat-sensitive rod 12 can be inserted. Note that other operations and effects are the same as those of the first embodiment, so their description will be omitted.

Further, FIGS. 8 and 9 show a third embodiment of the present invention. In the second embodiment, the square safety plate 1
8 and a spring 19. In this embodiment, a safety plate 20 is provided on the cooking main body 7 so as to be slidable left and right, and the safety plate 20 has an inclined portion 21 at its upper part. The safety plate 2o is normally located at a location where the space opposite the insertion hole 14 in the connection terminal 9 is closed by a spring 22. 23 is a stopper that restricts the sliding movement of the safety plate 20.

In the above configuration, when the play 10 is set, the convex portion 17 formed on the back side of the sloping portion 2 of the safety plate 20
1, slide the safety plate 20 to the right against the spring 22 and insert it into the insertion hole 14 in the connection terminal 9.
The opposing space is opened. Other operations and effects are the same as those of the first and second embodiments, so their description will be omitted.

In each of the above embodiments, the insertion path of the heat-sensitive rod is opened and closed by a safety plate, making it possible to connect the electrical connection plug only when the plate is attached. The connection is not specific to the route, and the point is that it is sufficient that the connection of the electrical connection plug is allowed only when the plate is attached.

Effects of the Invention As described above, when a plate is placed on the main body of the cooking device, the safety plate is moved in response to the operation only when the plate is placed correctly, and electricity is connected to the connection terminal. The connection plug can be connected to enable electricity to be applied to the heating element.

Also, if you forget to place the plate on the cooker or it is not placed correctly, the safety plate inside the connection terminal will be closed and the electrical connection plug and connection terminal will not be able to connect, causing heat generation. Since electricity cannot be applied to the cooking device, accidents such as fire caused by incorrect use can be prevented, and a cooking device that is highly effective in terms of safety can be realized.
