Description

[Detailed Description of the Invention] The present invention relates to a liquid heat-insulating container that can serve both as a boiler and as a heat-retainer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a liquid heat-insulating container according to an embodiment of the present invention will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a container main body 2, which is a lid pivotably attached to the container body 1, and 3 a container main body 1.
4 is a bottom lid installed in the bottom opening of the exterior case 3; 5 is a container body 1;
6 is a lower mouth member that connects the upper end opening of the liquid container 5 with the outer case 3; 7 is an inner lid that covers the upper end opening of the liquid container 5; 8 is a lid body 2;
9 is an operating member for driving the air pump 8;
0 is an inner stopper attached to the center of the inner lid 7; 11 and 12 are air passages and water passages inside the inner stopper 10; 1
3 is a liquid pumping pipe 14 whose upper end is connected to the water passage 12 of the inner stopper 10 and which is vertically installed at the inner bottom of the liquid container 5;
15 is a liquid spouting pipe extending laterally from the water passage 12; 16 is a lower spout at the tip of the auxiliary pouring pipe 15, 17 is a heater, and 18 is a heat insulating material.

The liquid pumping tube 13, the liquid pouring tube 14, and the pouring auxiliary tube 15 constitute a series of liquid pouring passages L.

The entire upper part of the container body 1 (i.e., the lower spout 1
6 side), a pipe cover 19 that covers the side circumference of the auxiliary pouring pipe 15 is attached. The pipe cover 19 has its upper edge engaged with the peripheral edge of the lower mouth member 6, and its lower end is fixed to the exterior case 3 with screws 20.

Furthermore, it has the same width as this pipe cover 19,
A display board 21 is continuously formed directly below the pipe cover 19 up to the lower part of the exterior case 2.
is provided, and the distal end outlet 16 of the auxiliary pouring pipe 15 is exposed to the outside from the lower end of the pipe cover 19,
At a position directly below this discharge port, the display plate 2
A transparent window 22 is provided at a constant length in the vertical direction.

The display plate 21 is fixed by having its upper end 21a engaged with the lower end of the pipe cover 19, and its lower end 21b being engaged with the lower edge of a notch 23 formed in the exterior case 3. 3 through a reinforcing member 24 with screws 25.

Further, inside the container body 1, there is a bottom portion of the liquid container 5 at a position that can be seen through the transparent window 22 of the display plate 21, in order to display the amount of remaining liquid in the liquid container 5 on the outside of the liquid container 5. A remaining amount display device 26 is provided, which is a display tube that connects the and intermediate portions.

The remaining amount display device 26 displays the remaining amount when the water level l' in the pipe becomes the same as the water level l in the liquid container 5.

Next, the operation of the illustrated liquid heat insulating container will be explained.

This liquid heat-insulating container heats the liquid W contained in the liquid container 5 to about 90° C. with a heater 17 and then keeps it warm. Pressurized air is blown into the liquid W in the liquid container 5 by the pressurized air.
is led out to the outside from a lower spout 16 through a series of liquid spout passages L consisting of a liquid pumping pipe 13, a liquid spouting pipe 14, and a spouting auxiliary pipe 15.

At this time, when the remaining amount of liquid in the liquid container 5 becomes approximately 1/2 or less, the water level l' is displayed on the remaining amount display device 26, and the water level l' is displayed through the transparent window 22 of the display board 21. The amount of liquid remaining in the liquid container 5 can be known by visually checking it.

Next, the effects of the liquid heat-insulating container of the present invention will be described.

According to the present invention, the display plate 21 is provided below the pipe cover 19 on the outer peripheral surface of the container body 1.
The container body 1 is placed in a position where it can be seen through the transparent window 22 of the container body 1.
Since the remaining amount display device 26 is provided with a display tube that connects the bottom of the liquid container 5 and the middle portion of the liquid container 5, when the liquid amount in the liquid container 5 has decreased to below the approximately middle position of the container body 1, The remaining amount can be displayed at a position directly below the pipe cover 19, and even if the liquid container has a low spout, the remaining amount can be displayed at a position that is easily visible to the user when pouring liquid. can. In addition, since the upper end of the display plate 21 is held by the lower end of the pipe cover 19 that protects the side circumference of the auxiliary pouring pipe 15, the pipe cover 19 that covers the side circumference of the auxiliary pouring pipe 15 is provided. In order to display the liquid level, there is no need to separately provide a liquid level display adjacent to the side, the mounting structure of the display plate 21 is simplified, and special mounting members are not required. Since this is no longer necessary, manufacturing costs can be reduced.

Furthermore, this display board 21 has a pipe cover 19
The pipe cover 19 has the same width and is formed continuously right below the pipe cover up to the lower part of the outer case 2, so that the lower end of the pipe cover 19 can be processed at the upper end of the display board 21. The mutual positioning of the pipe cover 19 and the display board 21 is also facilitated.

Further, the tip outlet 16 of the auxiliary pouring pipe 15 is exposed to the outside from the lower end of the pipe cover 19, and a transparent window 22 is provided at a position directly below the outlet and at a constant length in the vertical direction of the display board 21. Because of this provision, during pouring work, the position of the discharge port of the auxiliary pouring pipe 15 can be visually checked, and at the same time, the amount of remaining liquid can be checked from the transparent window 22 directly below, so the remaining amount can be reliably and easily measured, making it easy to use. It has the practical effect of making you feel better.
