A recess is formed in the upper plate to correspond to the periphery of the heating unit.

[Effect]

In this invention, if juice, which is an object to be heated, falls toward the vent while being heated, the juice is stored in the recess through the guide plate and the liquid receiving plate.

〔Example〕

Hereinafter, embodiments of this invention will be described with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of this invention, in which a sheathed heater 22 is provided at the upper part of a case 20, supported by a support fitting 21 and constituting a heating unit together with the support fitting 21. The sheathed heater 22 is connected to an energization inlet portion and an energization outlet portion 23, respectively. A heat shielding tube 24 is provided in the center of the support fitting 21.
A juice receiving plate 26 is attached to the lower side of the support fitting 21 and has a vent hole 25 formed in the center thereof with its tip facing into the heat shielding cylinder 24. This juice receiving plate 2
6 has a shape that is inclined downward toward the outer periphery. The outer peripheral edge of the juice receiving plate 26 is fixed to the heat shield plate 27 with screws 29. The U-shaped mounting bracket 30 is integrated with the juice receiving plate 26 and the heat shield plate 27 by screws 29. A rising peripheral edge portion 28a of the upper plate 28 is fitted into the mounting bracket 30. A recess 37 is formed in the upper plate 28 at the periphery of the heating unit. A protrusion 28b is formed on the upper plate 28, and an annular trivet 38 whose upper end surface is lower than the upper surface of the sheathed heater 22 is placed on the protrusion 28b.

At the center of the heat shield tube 24, a guide tube 31 is provided as a guide section that penetrates through the ventilation hole 25 and the heat shield plate 27. A temperature detection section 33 is provided at the upper part of the guide tube 31 to detect the temperature of the heated object.
A fixing plate 32 is attached to the lower part of the heat shield plate 27. Lead wire of temperature detection section 33 (not shown)
passes through the guide tube 31 and from the fixed plate 32 to the case 20.
