Description

[Detailed description of the invention] This invention relates to a heat insulating container that is equipped with a hot water storage chamber and a pump and can be used to supply hot water at any time.This device is designed to ensure the operation of a safety device that prevents hot water from leaking in the event of a fall, etc. It is intended to be able to be constructed at a lower cost.

Generally, this type of thermal container is equipped with body valves in the hot water supply route and the air supply route from the pump, as shown in Figure 4, to prevent hot water from leaking out when it falls over, but the body valves close due to their own weight. Because most of them operate, unless they are completely turned over, the closing force of the body valve is weak and the flow path cannot be completely closed, and if the water is shaken or tilted, the hot water may leak out and cause burns to children. This is accompanied by the danger of this, and the body valves and their receiving parts are formed in the hot water supply route and the air supply route, respectively, which are expensive.

This invention was devised to solve the above-mentioned problems, and will be explained in detail below with reference to embodiments shown in FIGS. 1 and 2.

1 is the thermal container itself. Reference numeral 2 denotes a hot water storage chamber formed within the main body 1, and a heating device 3 is provided at the bottom of the chamber 2 to heat and keep warm the hot water in the room.

A lid 4 is formed on the top of the main body 1 and located above the hot water storage chamber 2, and is easily opened and closed by pressing a locking device 5 that maintains the closed state.

Reference numeral 6 denotes an air pump provided in the lid body 4, which acts as a suppressor 9 against a bellows 8 which is always in a stretched state due to a spring 7.
Pressurized air is discharged from the air supply port 11 of the bottom plate 10 of the lid body 4 by pressing through the bellows 8, and an air supply valve 12 is provided at the top of the bellows 8.

Reference numeral 13 denotes an inner stopper that fits in the upper opening 14 of the liquid storage chamber 2 in a liquid-tight manner, and a vent tube 15 made of a soft material such as rubber is provided at the top. 4 bottom plate 10
The air pump 6 is configured to be in close contact with the air supply port 11 of the air pump 6.
The air is introduced into the air passage 16 inside the inner stopper 13 and sent into the liquid storage chamber 2.

Reference numeral 11 denotes a hot water supply pipe that extends downward from the inner stopper 13 and opens to the bottom of the hot water storage chamber 2, which pumps up hot water in response to pressure from the pump 6, and is a hot water pouring pipe that projects from the inner stopper 13 and opens to the outside of the main body 1. 18 to supply hot water.

19 is formed inside the inner stopper 13 and is connected to the hot water supply pipe 17 through the hot water pouring pipe 18.
A leak prevention valve is provided in the hot water supply path 20 that communicates with the hot water supply path 20 and is slidably attached to the interlocking rod 21.

Reference numeral 21 denotes a leak prevention valve which is interlocked with the valve 19 by an interlocking rod 22 and is provided in the air supply passage 16 in the inner plug 13;
is biased to open together with the valve 19.

Reference numeral 24 denotes a spring that urges the valve 19 upward and has a spring coefficient set smaller than that of the spring 23 so that the valve 19 and the valve 21 can be closed reliably.

Reference numeral 25 denotes a fall sensing section formed above the inner stopper 13, in which a sphere 27 is placed on a stand 26 shaped like a forest, and the interlocking rod 22 is made to protrude from the center of the stand 26. Normally, the weight of the sphere 27 presses the interlocking rod 22 to open the valve 19.21.
In the event of a fall, etc., the sphere 27 moves from the center of the pedestal 26 by sensing an inclination angle exceeding a predetermined inclination value a of the pedestal 26.
Due to the heating, the ejection valves 19 and 20 are opened to prevent hot water from leaking from the hot water storage chamber 2.

FIG. 3 shows another embodiment in which the valve rods 28 and 29 of the leakage prevention valve 19 and 21 are placed side by side and the valve rods are pressed by a pedestal 26 so that they can be opened and closed at the same time.

This idea is constructed as described above, in which a hot water supply pipe that pumps hot water from the hot water storage chamber into the hot water storage chamber is extended into the hot water storage container, which is equipped with a hot water storage chamber and an air pump, and can supply hot water at any time. The inner stopper is fitted liquid-tightly into the opening above the hot water storage chamber, and inside the inner stopper there is a hot water supply path that communicates with the hot water supply pipe and an air supply path that leads to the air supply from the air pump to prevent leakage. It is equipped with a valve and a sphere that moves when it detects the inclination of the container body above a certain level. Normally, the two valves are pressed open by the weight of the sphere, and in case of an emergency such as a fall, the pressure is released and the spring is released. Since we have installed a fall detection part that closes when the main body is biased, it closes when it senses when the main body is tilted more than a certain level, and the spring bias ensures that the leakage path is closed even if the main body is not completely overturned as in the conventional case. It is safe because it simultaneously blocks the hot water supply path and the air supply path, and the structure is simplified and inexpensive because it can simultaneously block two leakage paths with one fall sensing section.
