Description

[Detailed Description of the Invention] The present invention relates to an electric cooking device such as a hot plate, and is intended to provide an electric cooking device having a robust structure and good stability.

Generally, this type of electric cooker is equipped with a shielding plate that covers the back of the main body, but this heat shielding plate was fixed together with the handle via a space fitting, but when the handle is lifted up, the Each member had the disadvantage of being easily deformed and becoming unstable.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a plate-shaped main body made of aluminum, iron, etc., and equipped with a heater 2 on the back surface.

Reference numeral 3 denotes a connector provided on the back side of the main body 1, into which a temperature regulator that senses the temperature of the main body 1 and controls power supply to the heater 2 is inserted.

4 is a pair of bosses integrally formed on the back surface of the main body 1;
Two protruding top portions 5 are formed at the lower end, and an extending portion 4a extending inward is integrally formed.

Reference numeral 6 indicates concave-shaped projections formed on both sides of the boss 4.

7 is a mounting bracket with a U-shaped cross section, and there are 5 holes 8 at the bottom.
is formed.

This mounting bracket 7 covers the boss 4 and the protrusion 6 from below, and is fixed to the main body 1 by screwing a screw 9 passing through the center hole 8a of the five holes into the boss 4.

Reference numeral 10 denotes a handle that integrally includes a handle portion 11 and a leg portion 12, and is made of phenol resin or the like having poor thermal conductivity.

This handle 10 has a flat part 13 that makes surface contact with the mounting bracket 7, and this flat part 13 has a protrusion 14 that fits into the holes 8C at both ends of the mounting bracket 7 and a hole 8b in the middle of the mounting bracket 7. It has a hole 15.

16 is a screw that passes through the hole 15 of the handle 10 and screws into the intermediate hole 8b of the mounting bracket 7 to fix the handle 10 to the mounting bracket 7; in this case, the protrusion 14 of the handle 10 is inserted into the mounting bracket 7 By fitting the screws 16 into the holes 8C at both ends in advance, the screws 16 can be screwed together easily.

Moreover, the rib 10 formed on the handle 10 by this fitting
a and the protrusion 14 sandwich the boss 16 and the mounting bracket 7, and the handle 10 is securely fixed.

Further, the flat surface portion 13 of the handle 10 has an integral projecting flat surface portion 17 that projects inwardly, and this projecting flat surface portion 17 is formed with a projecting portion 18 that projects upward.

19 is a heat shield plate that covers the back surface of the main body 1, and a peripheral wall 2 is provided on the outer periphery.
It is formed into a tray shape with 0.

The peripheral wall 20 has a pair of large tongue portions 21 facing each other, and a pair of small tongue portions 22 located between the large tongue portions 21 and facing each other. It is smaller than the tongue portion 21 and has a groove 23.

In addition, small holes 24 are formed on the entire surface of the heat shield plate 19,
A step portion 25 is formed near the small tongue portion 22 corresponding to the protruding flat portion 17 of the handle 10, and a hole 26 is formed in this step portion 25, and a phenol resin is formed near the large tongue portion 21. A leg 27 made of aluminum is fixed.

The heat shield plate 19 is fixed by placing the stepped portion 25 on the protruding flat portion 17 of the handle 10, fitting the protruding portion 18 into the hole 26 of the stepped portion 25, and inserting the groove 23 of the tongue portion 22 into the extending portion of the main body 1. Exit part 4a
When the handle 10 is fixed to the mounting bracket 7, the small tongue portion 22 is pushed against the back surface of the main body 1 and fixed.

In this case, since the large tongue portion 21 is larger than the small tongue portion 22, it is pressed more strongly against the back surface of the main body 1.

In the above configuration, a downward force F is applied to the handle portion 11 of the handle 10.
When F' is applied to the protruding flat part 17 of the handle 10, a reaction force F'
acts, and this force F' is received by the small tongue portion 22, so that the mounting bracket 7 is not deformed and is strong and stable.

Furthermore, when the main body 1 becomes hot due to use, the heat is conducted to the mounting bracket 7 via the boss 4 and the protrusion 6, but the contact area between the boss 4 and the mounting bracket 7 is determined by the size of the top 5 and is small. Since the temperature rise of the metal fitting 7 is low and the handle 10 and the mounting metal 7 are fixed by the screw 16 screwed into the hole 8b in the middle of the mounting metal 7, the heat transfer path to the handle 10 is long, and the heat transfer path of the handle 10 is long. The temperature doesn't get too high.

As a result, the phenolic resin used for the handle 10 does not need to be an expensive high-grade product with excellent heat resistance, and even if a common one is used, it will not be deformed by heat, and there is no need for a spacer, making assembly easy. The fixation of 10 is ensured.

In addition, the air flowing in through the holes 24 provided in the heat shield plate 19 is
Daikichi Katabe 21. It flows out from the gap secured between the back surface of the main body 1 and the peripheral wall 20 of the heat shield plate 190 by the small tongue portion 22,
The heat shield plate 19 is prevented from becoming high temperature.

As is clear from the above description, according to the present invention, the handle can be securely fixed, and an electric cooking appliance that is robust and has excellent stability can be obtained.
