Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an electric jar pot, and more specifically, to the structure of a lid in an electric jar pot.

(b) Prior Art As shown in Fig. 1, a conventional electric jar pot includes a jar pot main body 1 having an outer cylinder X and an inner cylinder Y, a heater 2 attached to the inner cylinder around the body, and a water supply for the main body. It is mainly composed of an upper lid 3a and a lower lid (inner lid) 3b, and this upper lid locks an inner lid on its lower surface, the lower surface of which is formed by a horizontal surface, and the inner lid has a vertically extending inside thereof. A large number of penetrating steam vent holes (through holes) 4 are formed.

Steam generated from the heated water in the pot body 1 passes through the steam vent 4 of the inner lid, hits the lower surface of the upper lid, condenses at a high temperature, and adheres to the lower surface of the upper lid. For example, in order to check the amount of hot water remaining in the pot body 1, when the top lid 3a is opened and tilted, the condensed high-temperature water that has adhered to the bottom surface of the top lid flows out from between the bottom surface of the top lid 3a and the top surface of the bottom lid 3b, and may cause damage to your hands, etc. There was a risk of getting burned.

(c) Purpose of the invention This invention was created in view of the above circumstances, and is intended to allow high-temperature condensed water that condenses on the bottom surface of the top lid to be returned from the bottom surface of the top lid into the pot body when the top lid is sealed.

(d) The structure of this invention is that the upper lid and the lower lid, which is fixed to the underside of the upper lid and has a number of steam vent holes distributed therein, can be detached or opened/closed on the cylindrical heat-insulating jar pot body equipped with a heater. In addition, the electric jar pot has the lower surface of the upper lid tilted downward from the center toward the inner wall of the pot body.

(e) Examples This invention will be described in detail based on the examples shown in the figures below. Note that this invention is not limited to this.

Figures 2 and 3 show the overall structure of the electric jar pot 5, in which 6 is a rectangular tube-shaped vertical insulating jar pot body, with a water supply port 7 formed in the upper part, and an outer case (outer cylinder) 8 and this outer cylinder. It consists of an insulated inner case (inner cylinder) 10 fixed with a fitting 9 inside, and a lid 11 is removably attached to the water supply port to seal the water supply port 7. The outer cylinder 8 has a sprue 12 formed on the upper front side, and a handle 1 on the opposite side of the sprue.
3, a container socket 14 and heating lamps 15 and 16 are respectively attached to the lower part of the outer cylinder.
The entire outer wall of the inner cylinder 10 is covered with a heat insulating material 17, a band heater 18 is wrapped around the lower outer wall of the inner cylinder between the heat insulating material and the inner cylinder, and a temperature controller (main thermos) is installed on the inner wall of the inner cylinder. Tatsuto) 19
is embedded. Note that 20 and 21 are protector fuses and fuse covers.

The lid body 11 consists of a heat-insulating upper lid 22 and an elastic lower lid (inner lid) 23 on the lower side of the upper lid. Further, its lower surface is inclined downward from this protrusion toward the peripheral side wall of the inner cylinder 10. On the other hand, the inner lid 23 has a fitting recess 28 at the center of its upper surface that fits into the outer surface of the upper lid protrusion 25 and is locked to the upper lid 22, and a slidable slide that slides vertically inside the upper lid recess 24 is provided on the lower surface of the inner lid 23. The movable pin 26 is provided protrudingly, and a large number of steam vent holes (through holes) 27 are distributed in the vicinity of the center of the movable pin 26 and extend vertically through the entire periphery of the movable pin 26 . Note that 29 is an inner lid packing.

FIG. 4 shows a heating electrical circuit diagram,
Band heater 18a for heating in AC100V power circuit
and a band heater 18b for heating and heat retention are connected in parallel, and a main thermostat 19 is connected in series to the band heater for heating.

Next, the electric jackpot 5 having the above configuration
The flow of steam inside the inner cylinder 10 will now be described.

First, when the inner cylinder 10 is sealed with the upper lid 22 and the inner lid 23 and the band heater 18 is heated, the water in the inner cylinder 10 becomes high-temperature hot water, and high-temperature steam is generated from the hot water surface. And this steam is the third
As shown in the figure, the steam passes through the steam vent 27 of the inner lid, hits the lower surface 24 of the upper lid, and condenses while maintaining a high temperature. Therefore, this condensed water (condensed steam) flows toward the inner wall of the inner cylinder 10 along the inclination direction of the lower surface 24 of the upper lid due to its own weight, and accumulates near the steam vent 27 near the inner wall of the inner cylinder. The condensed steam is then dropped into this steam vent 27 by the pressing force of the condensed steam flowing toward this vent, and the inner cylinder 1
Return to within 0.

As described above, the electric jar pot 5 can prevent condensed steam from accumulating on the lower surface of the upper lid by smoothly returning the condensed steam on the lower surface 24 of the upper lid into the inner cylinder 10, so that when the upper lid 22 is opened,
Condensed steam does not flow down from the top lid, thus preventing burns to hands and the like.

(f) Effects of the device This device tilts the bottom surface of the top lid downward, so that the high temperature condensed water that condenses on the bottom surface of the top lid is caused to flow along the slope of the bottom surface of the pot body while the top lid is sealed due to its own weight. Since the water can flow toward the inner side wall and fall into the inner cylinder through the steam vent hole near the side wall, it is possible to prevent high-temperature water from flowing out from the lower surface of the upper lid and the upper surface of the lower lid when the upper lid is opened. It can prevent you from getting burned.
