Description

[Detailed Description of the Invention] The present invention relates to a closed container water heater.

BACKGROUND ART Conventionally, in the case of a closed container such as a sealed electric water heater, it is necessary to provide a steam vent to allow steam generated during boiling water to escape. However, if the main body of the container falls over, there is a risk that hot water will flow out from the steam port, so a sub-water valve device must be provided within the steam port. In addition, since the steam vent is usually located on the top of the seal, there is a risk of blocking the steam vent if you accidentally cover it with a cloth while in use.In this case, there will be no place for the steam to escape, and the internal pressure will increase. It is dangerous.

The present invention was developed in view of these problems, and its purpose is to prevent hot water from flowing out in the event of a fall by forming a steam port in the hot water supply path and using a weight valve to open and close the hot water supply path. To provide a water heater with a closed container in which a steam port is prevented from being accidentally blocked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention and its embodiments will be described below with reference to the accompanying drawings.

FIG. 1 shows an electric water heater that is a first embodiment of the closed container according to the present invention, in which a shoulder body 2 is provided with a spout 3 and a handle 4 integrally provided at the upper end of the body 1.
is mounted and fixed. An inner container 5 having a heater 6 wrapped around the outer periphery of the lower part is housed inside the body 1, and the upper end of the inner container 5 is connected to the shoulder body 2 by a seal rubber 7.
It is sealed and fixed against. Above body 1, shoulder body 2
and the inner container 5 constitute a container body A.

A sealing stopper 8 is removably attached to the opening of the container body A in a sealed state with a seal rubber 7, and the sealing stopper 8 is composed of a stopper lid 9, a stopper main body 10, and a stopper bottom plate 11. There is. The tap body 10 is formed with a hot water supply passage 12 that communicates the spout 3 with the inside of the inner container 5. The hot water supply passage 12 includes a valve chamber 13 and a weight valve 16 that can freely move up and down within the valve chamber 13. is provided. A hot water supply port 14 is formed at the upper end of the valve chamber 13 and can be freely sealed on the upper surface of the weight valve 16.
Valve seat 15 has a plurality of ribs protruding from the lower part of valve seat 3.
is formed. On the other hand, the lower end of a vertically movable rod 17 is in contact with the upper surface of the weight valve 16, and the lower surface of the weight valve 16 is formed into a tapered shape.
It is designed to be stably held with a gap in the center of 5. A lever 18 is attached inside the stopper body 10 so as to be movable in the front and rear direction, and a spring 1
9 is biased backwards. Lever 1 above
8 corresponds to the upper surface of the rod 17 when the lever 18 is moved forward, and restricts the upward movement of the weight valve 16 to prevent the weight valve 16 from closing the hot water inlet 14. A push button 20 is provided at the upper end of the handle 4 so as to be movable forward and backward, and the tip of the push button 20 corresponds to the rear end surface of the lever 18.

Note that 21 is an air inlet port provided on the rear side of the seal plug 8, and this air inlet port 21 is sealed by the protrusion 18b of the lever 18 when the lever 18 is in the rear position, and when the lever 18 is in the forward position. When moved, the protrusion 18b opens the air inlet 21, allowing outside air to flow into the inner container 5.

Here, the operation of the water heater having the above configuration will be explained. First, when boiling water, steam generated inside the inner container 5 is exhausted through the gap between the weight valve 16 and the valve seat 15, the hot water supply port 14, and the spout 3, thereby preventing an increase in internal pressure. If the container body A falls in this state, since the weight valve 16 and the rod 17 are in a free state, the weight valve 16 will slide on the valve seat 15 and the top surface of the weight valve 16 will close the hot water supply port 14. Prevent hot water from flowing out. To supply hot water, press button 20.
is pressed to move the lever 18 forward, and the tip 18a of the lever 18 restricts the position of the upper surface of the rod 17. This restricts the upward movement of the weight valve 16, and when the container body A is tilted by holding the handle 4, the hot water flows through the same path as the steam exhaust path, that is, the gap between the weight valve 16 and the valve seat 15, and the hot water supply. Hot water is supplied through the spout 14 and spout 3. At this time, the air inlet 2
1 is opened, hot water can be supplied smoothly. When the pressing force on the push button 20 is released, the lever 18 is returned to the rear by the spring 19, and the restricting force on the rod 17 is released.

FIG. 2 shows another embodiment of the present invention. In this case, a rod 17 is integrally fixed to the upper surface of the weight valve 16, and the weight valve 16 is supported in the vertical direction by the bearing hole 11a of the bottom plate 11. It is designed so that it can only operate in Reference numeral 22 denotes a lid lever, and the lid lever 22 and a protrusion 8a protruding from the rear end of the lid 8 allow the lid 8 to be attached to and removed from the container body A. Note that in FIG. 2, parts that are the same as those in FIG.

As is clear from the above explanation, according to the present invention, a valve chamber and a weight valve are provided in the hot water supply path, and when hot water is not being supplied, steam is exhausted from the gap between the weight valve and the valve seat through the spout. This prevents the internal pressure from rising, and there is no need to worry about the steam vent being blocked by a cloth or the like. Additionally, in the event of a fall, the weight valve moves up and closes the hot water supply port, so there is no risk of hot water leaking out.
Furthermore, when hot water is being supplied, the lever is moved and the upward movement of the weight valve is regulated via the rod to hold the hot water supply opening in an open state, so that hot water can be supplied without any trouble.
