Description

[Detailed description of the invention] The present invention heats and keeps water contained in a metal inner container with a heater provided at the bottom of the inner container, and which is connected to the lower end of the side periphery of the inner container. The present invention relates to a kettle that allows hot water inside the pot to be poured out to the outside via an opening/closing cock.

Conventionally, in this type of so-called natural fall type water boiling pot, the water passage from the inner container side periphery to the opening/closing cock is formed horizontally or with a slight downward slope. Even though the liquid is heated on the inner container side, no convection occurs within the passageway, so the temperature of the liquid in this area is lower than that in other areas.

Therefore, when pouring hot water by operating the opening/closing cock initially, the low-temperature hot water will be poured out, which poses a problem when high-temperature hot water is required, such as when making coffee.

In view of the above-mentioned problems, the present invention creates an upward slope in the passageway between the pouring outlet at the lower end of the side circumference of the inner container and the opening/closing cock, thereby creating convection in the liquid inside the passageway during heating. The purpose of this is to eliminate temperature differences in the liquid content in each part.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A water kettle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes the pot body, 2 a lid that covers the upper opening of the pot body 1, 3 the footrest of the pot body 1, 4 the exterior case of the pot body 1, and 5 the contents of the pot body 1. 6 is a shoulder member that connects the opening of the outer case 4 and the inner container 5, 7 is the bottom member of the pot body 1, and 8 is the inner container 5.
A heater 9 provided on the bottom side periphery is a heat insulating material.

The outer case 4 and the bottom member 7 are made of iron plate, and the inner container 5 is made of stainless steel.

Further, the leg stand 3 and the shoulder member 6 are made of synthetic resin.

A molten metal pouring outlet 10 is formed at the lower end of the lateral circumference of the inner container 5 and opens slightly above the inner bottom surface.

In this way, the content liquid is always left between the bottom surface of the inner container 5 and the outlet 10, which is effective in preventing boiling.

The connecting pipe for connecting the opening/closing cock 11 to the outlet 10 is composed of an inner pipe part 12a and an outer pipe part 12b, which are connected via a joint 13 fixed to the outer case 4. The length of the portion 12b is such that the outlet of the opening/closing cock 11 can be separated from the main body 1 by the radius of a liquid receiving container (not shown) such as a pot.

Therefore, in this embodiment, the inner tube part 12a and the outer tube part 12
b has an upward slope, and the inner tube part 12a and the joint 13
A series of water passages constituted by the inner and outer pipe portions 12b are generally inclined upward toward the opening/closing cock 11 side.

Next, to explain the operation of the water boiling pot shown in the figure, the water W stored in the inner container 5 is heated by the heater 8 while causing convection. The water in the passageway leading to the opening/closing cock 11 is also heated by convection.

Therefore, hot water at a high temperature can be obtained from the beginning of pouring.

Next, we will discuss the effects of the water boiling pot of this invention.

That is, according to the present invention, the passageway that communicates between the pouring outlet 10 provided at the lower end of the side circumference of the inner container 5 and the opening/closing cock 11 for dispensing is sloped upward toward the opening/closing cock 11 side. As a result, convection can be generated in the water in the water passage during heating, so that the water in the water passage is heated in the same way as the water in the inner container 5, and from the beginning of pouring. You can get hot water at a high temperature.

Therefore, there is a practical effect that it is possible to provide a kettle pot that can be used for a wide range of uses, even for things that require high-temperature hot water such as coffee.
