Description

[Detailed Description of the Invention] The present invention relates to a cooking appliance that prevents a rise in temperature of a guard surrounding a hot plate.

A cooking device, generally referred to as a hot plate, consists of a frame surrounding a hot plate with a heating element such as a sheathed heater cast into the bottom surface, and the heating element is supplied with electricity through a power supply plug. The hot plate is heated so that grilled food etc. can be prepared on the hot plate.

By the way, in this type of cooking device, the frame body is generally provided with guards located outside both edges of the hot plate to prevent accidental contact with the heated hot plate.

However, in the conventional type, the guard itself becomes quite hot due to the radiant heat from the hot plate, and there is a drawback that dangers such as burns cannot be reliably prevented.

Therefore, it is possible to insert a heat insulating material between the hot plate and the guard to block heat propagation between the two, but this would increase the number of parts by the amount of heat insulating material, making assembly difficult. This is not preferable because the work becomes complicated and costs increase.

The present invention was developed in consideration of the above points, and its purpose is to use heat insulating materials, etc. in a cooking appliance in which a frame surrounding a hot plate is provided with guards located outside both edges of the hot plate. The purpose is to prevent the temperature of the guard from rising without causing any damage.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on the Example shown in drawing.

First, the embodiment shown in FIGS. 1 to 3 will be described.

Figure 1 shows the external appearance of the cooker. A heating element 2 such as a sheathed heater is cast into the bottom surface of a hot plate 1. The bottom surface and periphery of this hot plate 1 are surrounded by a frame 3. There is.

In addition, 4 in the figure is a power supply plug with a temperature controller.

As shown in FIG. 2, the frame 3 has plate-shaped guards 6.6 erected from both sides of the bottom plate 5 and positioned outside both edges of the hot plate 1, and has handles T and 1 at both ends. It's something you wear.

As shown in FIG. 3, each guard 6 is curved in the vertical direction so that its outer surface is convex.

Then, a heat shield plate 8 is suspended downward from the upper edge of each guard 6, a space 9 is formed between the heat shield plate 8 and the guard 6, and a space 9 is formed between the heat shield plate 8 and the periphery of the heat plate 1. gap (gap 10
Further, an air intake hole 11 is provided at the periphery of the bottom plate portion 5, and an air passage 12 extending from the air intake hole 11 to the gap 10 is formed.

The heat shield plate 8 is integrally formed of a single plate material by folding back the upper edge of the guard 6, and the bottom plate portion 5 and the guard 6 are joined by machine screws 13 or the like.

Furthermore, the inner surface of the guard 6 and the surface of the heat shield plate 8 are coated with white, silver, etc., a heat reflective layer 6A, which is coated with printing, plating, etc.;
8A is formed.

With the above configuration, heat conduction from the hot plate 1 to the guard 6 is blocked by the gap 10, and radiant heat from the hot plate 1 in the direction of one direction is blocked by the heat shield plate 8.

Therefore, in order for heat to propagate from the heat plate 1 to the guard 6, it must first be transmitted from the heat plate 1 to the heat shield plate 8 by radiation, then from the heat shield plate 8 to the guard 6 by radiation and conduction; Heat reflective layers 6A, 8A are provided on the inner surface of the heat shield plate 8 and on the surface of the heat shield plate 8.
is formed, most of the radiant heat is reflected, and low-temperature air outside the frame 3 reaches the heat shield plate 8 through the air passage 12 extending from the air intake hole 11 provided at the periphery of the bottom plate portion 5 to the gap 10. Since the current flows along the sides, the temperature rise of the heat shield plate 8 is actively suppressed by the synergistic effect of these, and as a result, the guard 6 is maintained at a relatively low temperature without using any special heat insulating material etc. It turns out.

Therefore, there is no danger of getting burned even if the guard 6 is touched during heating of the hot plate 1, and the structure is simplified and the assembly work is facilitated, thereby reducing costs.

Note that since the ventilation passage 12 is formed only at the peripheral edge of the hot plate 1, there is no risk of reducing the heating efficiency of the hot plate 1.

Furthermore, by connecting the heat shield plate 8 to the upper edge of the guard 6, the guard 6 can obtain sufficient strength even if the plate thickness is made slightly thinner, and the strength of the guard 6 can be increased while reducing the weight. It is possible to obtain excellent effects such as being able to increase the amount of water.

Next, the embodiment shown in FIGS. 4 to 1 will be described.

In this embodiment, a hot plate 14 is detachably attached to a frame 15 as shown in FIG. 5, and handles 16 and 17 are provided at both ends of the hot plate 14 and frame 15, respectively.

Further, as shown in FIG. 6, on the bottom surface of one end of the hot plate 1, there is a connecting terminal 18 connected to the plug terminal of the power supply plug 4, and a cylindrical heat sensing opening into which the heat sensitive rod 4A provided with the power supply plug 41 is inserted. 19 are provided adjacent to each other.

The connection terminal 18 is connected to the end of a heat generating element such as a sheathed heater cast into the lower surface of the hot plate 14, and the opening of the heat sensing port 19 is opened and closed by a shielding plate 20.

The shielding plate 20 has its center portion rotatably supported on the lower surface of the heat plate 1, and is always biased in a direction to close the heat sensing port 19.

Further, both handles 1γ of the frame 15 have a recess 21 in the middle portion, and the handle 16 of the hot plate 14 is accommodated in each recess 21, and the outer surface of one handle 1T has the hot plate 14 Plug insertion port 22 leading to the connection terminal 18 and heat sensing port 19 of
is provided.

Furthermore, a plug insertion opening 2 is provided on the upper surface of the bottom plate portion 23 of the frame body 15.
A blocking release protrusion 24 is provided at the inner position of the hot plate 1.
4 is placed on the frame 15, the protrusion 24 presses one end of the shielding plate 20 to rotate the shielding plate 20 in the opening direction.

Therefore, when the heat plate 14 is placed on the frame 15, the heat-sensitive rod 4A of the power supply plug 4 can be inserted into the heat detection port 19 through the plug insertion port 22, and at the same time, the plug terminal of the power supply plug 4 can be connected to the connection terminal 18. However, when the heat plate 14 is removed from the frame 15, the heat sensing port 19 is connected to the shielding plate 20.
The power supply plug 4 is automatically closed and closed, and connection of the power supply plug 4 in a state where it is removed from the frame body 15 is prohibited.

Further, below each handle 16 of the hot plate 14, a locking protrusion 25 is provided which projects outward as shown in FIG.
One handle 11 has a locking recess 26 into which the projection 25 fits from the inside, and the other handle 11 has a locking recess 26 into which the projection 25 fits from the inside.
A hook 2T that can be freely engaged and detached from each of the hooks 5 is provided.

Therefore, by removing the hook 21 from the protrusion 25 and pulling out the other protrusion 25 from the locking recess 26, the hot plate 14 can be removed from the frame 15;
When the hook 2γ is fitted into the locking recess 26 and then the hook 2γ is engaged with the other protrusion 25, the hot plate 14 is fixed onto the frame 15.

In this state, the hot plate 14 is positioned at an appropriate position on the frame 15 by fitting the handle 16 into the recess 21 of the frame 15.

Also in this embodiment, a heat shield plate 29 similar to that of the previous embodiment is provided inside each guard 28 of the frame 15, and an intake hole 30 is provided at the periphery of the bottom plate portion 23.
