Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to cooking appliances such as hot plates and pots used in general households.

Conventional configuration and its problems Conventionally, this type of cooker is generally used on a table, but since these cookers heat the hot plate to perform cooking, this heat The temperature of the table surface increases due to the temperature of the board, resulting in the surface being burnt and its durability being significantly reduced. In order to solve this problem, the height of the hot plate can be increased and the distance from the table surface can be increased.However, in this case, the height of the hot plate becomes high and it becomes difficult to use. It had the disadvantage of being stored away.

Furthermore, since this is a cooker that is used on a table, the outer surface of the heat shield that covers the back of the heating plate may be painted, etc., in order to harmonize well with the table and create a good atmosphere during use. However, the resin layer of the heat shield board absorbs and transmits the heat from the heat plate well, further raising the temperature of the table surface.As a result, the usability and appearance design are not satisfactory. I couldn't get anything.

In addition, in order to solve this problem and improve the external design without increasing the height of the heating plate, we added heat to only a part of the outer periphery of the side and bottom sides of the heat shield that covers the back of the heating plate. A method is used in which painting is applied and the central part of the bottom is not painted, that is, Figures 1 and 2
As shown in the figure, the center part of the bottom of the heat shield plate is formed into a convex or concave shape, and a masking jig etc. is placed on this part to apply the painting, so that the center part of the bottom is not painted. In other words, in Fig. 1, the bottom center of the heat shield plate 1 is formed into a convex shape as a whole, and in this case, it is necessary to bend the entire outer circumference of the masking jig 2. Since it is difficult to process and to make the convex surface of the heat shield plate 1 flat, the masking jig 2 becomes slightly floating, and as a result, a gap is created at the outer periphery. During this time, the paint got into the product, making the boundary between the painted and unpainted parts very unclear, which degraded the product's marketability.

Furthermore, in Fig. 2, the bottom center of the heat shield plate 3 is formed into a concave shape as a whole, and in this case, the masking jig 4 is set in this concave part to apply the coating. Since the paint is applied to the inside of the recess, the paint accumulates in the recess, and as a result, the boundary becomes very unclear, similar to the above-mentioned Fig. 1, and the product quality deteriorates.

Purpose of the Invention The present invention solves these conventional problems by making the exterior design harmonious with the table and keeping the temperature of the table surface to a safe temperature without increasing the height of the heating plate. The purpose is to provide a cooking device that can.

Structure of the Invention In order to achieve the above object, the cooker of the present invention has the following features:
It has a heat plate having a heating element on its back surface, and a heat shield plate covering the back surface of the heat plate, and a convex rib extending away from the heat plate is provided in an annular shape on the bottom plane part of the heat shield plate, and further A resin layer is provided by painting on the outer surface of the outer periphery located outward from the convex ribs of the heat shield plate. According to this configuration, when painting the heat shield plate, the masking jig is applied to the convex ribs. Because it comes into contact with the ribs, there will be no gap around the outer periphery of the center of the bottom of the heat shield, and as a result, the paint will not get into the center of the bottom of the heat shield. The boundaries between parts become clearer, and as a result, the product quality can be improved, and
It is also extremely easy to paint heat shield plates.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figure 3, 5 is a hot plate;
A heating element 6 is integrally provided on the back surface. Further, the back surface of the hot plate 5 is covered with a heat shield plate 8 with a space A left therebetween so that the heat from the hot plate 5 is not directly transmitted to the table surface 7. 9 is a leg that supports the heat shield plate 8.

The heat shield plate 8 has a rising portion 10 almost all around the circumference so as to cover the back surface and a part of the side surface of the heat plate 5, and the tip of the rise portion 10 touches the flange portion of the outer circumference of the heat plate 5. I'm letting you touch me. The bottom of the heat shield plate 8 is flat, and this flat part has a convex rib 11 extending away from the heat plate 5, and the convex rib 11 is provided in an annular shape around the entire circumference. Further, the inner side of the convex rib 11 of the heat shield plate 8 has a concave shape lower than the surface of the convex rib 11, and a plurality of through holes 12 are provided on the surface inside the convex rib 11.
Further, in order to improve the appearance design and harmonize with the table, this heat shield plate 8 is provided with a resin layer 13 by painting on the outer surface of the outer periphery located outward from the convex ribs 11. . Note that if a resin layer is provided inside the convex ribs 11, this resin layer has good heat absorption and transmission, which increases the temperature of the table surface 7. Therefore, the area inside the convex ribs 11 is made of sheet metal. It will be treated with plating, etc., and no resin layer will be provided by painting.

Reference numeral 14 represents a masking jig for painting the outer surface of the outer peripheral portion located outward from the convex ribs 11 of the heat shield plate 8; Guide pins 15 are provided at positions corresponding to the plurality of through holes 12 provided in the heat shield plate 8, respectively.

Then, the masking jig 14 is set by inserting the guide pin 15 into the through hole 12 of the heat shield plate 8, and by painting the heat shield plate 8 in this state, the masking jig 14 is positioned outwardly from the convex rib 11. The outer surface of the periphery is painted, and the inside is left unpainted.

With the above configuration, even if the center part of the bottom part of the heat shield plate 8 is deformed, the annularly provided convex rib 11 and the masking jig 14 are in contact with each other, so that no gap is created around the outer periphery of the center part of the bottom part. , so the paint will not get in. In addition, the outer periphery of the convex rib 11 and the masking jig 14 are of the same size, and there are no recesses, so there is no accumulation of paint, and as a result, the boundary between the painted part and the unpainted part is very clear. It is clean and can be easily painted.

Effects of the Invention As is clear from the above embodiments, according to the present invention, a convex rib extending away from the hot plate is provided in an annular shape on the bottom plane part of the heat shield plate that covers the back surface of the hot plate, and Since a resin layer is painted on the outer surface of the outer periphery located outward from the convex ribs of the hot plate, the boundary between painted and unpainted parts becomes clear, resulting in improved marketability. In addition to improving heat shielding, it is extremely easy to paint the heat shield plate, and the temperature of the table surface can be kept at a safe level without increasing the height of the heat plate, and the exterior design is in harmony with the table. It can provide cooking utensils.
