Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a hot plate in which a plate frame is detachably attached to the outer periphery of the plate.

[Prior art]

In conventional hot plates, a plate frame is attached to the outer periphery of the plate that has a heating element to prevent burns or for decoration purposes, and the plate and plate frame are detachable for the purpose of easy cleaning. However, the plate side requires a connection terminal and a plug cover to enable electrical connection with the heater, and the plate side requires an insertion hole for inserting the plug cover.

In the conventional hot plate, when the plate and plate frame were assembled, the plug cover part was simply passed through the insertion hole, so looseness occurred between the plug cover and the plate frame, and If a tight fit is attempted, not only will it be difficult to attach and detach the plate, but the heat from the relatively high temperature plug cover will be transferred to the plate frame, making it difficult to avoid a rise in temperature of the plate frame. It has the disadvantage that it cannot be done.

〔the purpose〕

The present invention was devised to eliminate the above-mentioned drawbacks, and by attaching a reinforcing plate to the inner surface of the insertion hole of the plate frame, it provides strength resistance, prevents the temperature rise toward the plate frame side due to the plug cover, and A part of the reinforcing plate is cut and raised to provide an elastic piece, and the plug cover is held in pressure contact with the elastic piece to prevent the plug cover and the plate frame from sticking together. be.

〔Example〕

1 is an elliptical plate with a heater (not shown) attached to the back side, and one end thereof has an insertion hole 2 for inserting a heat-sensitive rod of a temperature controller (not shown). Connecting terminals 3 for connecting the heating heater are provided protruding from both sides of the hole 2, and a through hole 4 facing the fitting hole 2 is provided on the outer periphery of the connecting terminal 3.
A plug cover 5 having a hole therein is provided. This plug cover 5 is fixed to the back side of the plate 1 by screws 6 through a mounting portion 5a.

Reference numeral 7 designates a box-shaped plate frame surrounding the outer periphery of the plate 1, with a mounting hole 8 having the same shape as the plate 1 formed on the top surface, and a notch in the portion of the plate 1 facing the plug cover 5. 9, and an insertion opening 10 through which the plug cover 5 is inserted is formed in the end face of the recessedmost part of the notch 9.

Reference numeral 11 denotes a metal reinforcing plate attached to the inner surface of the insertion opening 10, which is composed of an upper reinforcing plate 11a and a lower reinforcing plate 11b. Several elastic pieces 1
2, 12... are cut and raised, and when the plug cover 5 is penetrated into the insertion hole 10, the elastic piece 1
2, 12, . . . are adapted to hold the plug cover 5 in pressure contact with each other. The tips of the elastic pieces 12, 12... are bent into a dogleg shape so as not to damage the plug cover 5.

Incidentally, reference numerals 13 and 13 are mounting screws for fixing the reinforcing plate 11 to the plate frame 7.

Therefore, the plate 1 is inserted into the mounting hole 8 of the plate frame 7.
When attaching the plug cover 5 to the plate frame 7, tilt the plate 1 diagonally downward.
When inserted into the insertion hole 10 of the plug cover 5,
is an elastic piece 1 formed by cutting and raising the reinforcing plate 11
2, 12, etc., and the plate 1 is mounted in the mounting hole 8 of the plate frame 7. At this time, the plug cover 5 does not get stuck inside the insertion opening 10, and a gap is formed between the plug cover 5 and the reinforcing plate 11, so that the heat from the plug cover 5 does not spread to the reinforcing plate 11. Plate frame 7
This prevents the temperature from increasing in the plate frame 7.

〔effect〕

As described above, the present invention provides a hot plate in which a plate frame is detachably attached to the outer periphery of the plate.
An insertion hole for inserting the plug cover provided on the plate side is formed in one side of the plate frame, and a reinforcing plate with an elastic piece cut and raised is attached to the inner surface of the insertion hole, and the elastic piece is used to secure the plug cover. Since the plate is held in pressure contact with the plate frame, it is not only easy to attach and detach the plate and the plate frame, but also the plug cover can be prevented from wobbling by being held in pressure contact with the elastic piece. Since a gap is formed between the plug covers, a temperature rise to the plate frame through the plug cover can be prevented, which is a remarkable effect.
