Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a water heater with a whistle, which blows a whistle provided on the lid to notify boiling when the water inside boils. .

[Conventional technology]

A water heater with a whistle blows a whistle using the steam pressure generated when water boils, and if the generated steam leaks from a place other than the whistle, the whistle will sound. Therefore, the points where steam leaks must be sealed.

For the type with a whistle attached to the pouring spout, the spout must be closed with a lid with a whistle and the lid with a whistle must be sealed tightly when boiling water, and when pouring water, The lid with whistle must be opened.

When installing a lid on the water supply opening, it is not necessary to provide a lid on the spout, but if the water level in the water heater is not high, steam generated in the water heater may pass through the spout. There was a drawback that the sound leaked outside and the whistle did not blow.

In order to eliminate this drawback, a partition wall is installed between the spout and the water heater body to prevent steam leakage unless the water level inside the water heater falls below the minimum standard water level. There is a container (see Utility Model Publication No. 45-3344).

According to the technique, as shown in FIG. 3, a partition wall 3 is provided to partition the water heater body 1 and the pouring spout 2,
A passage 4 formed by drilling a large number of holes is provided below the partition wall 3 so that the height of the passage 4 is lower than the minimum standard water level L for the amount of water that can be put into the water heater body 1. Therefore, when the water level is higher than the lowest reference level L, the steam generated in the water heater body 1 will not flow out to the pouring port 3, and therefore the water heater body 1
A whistle provided on a whistle-equipped lid 6 that closes the water supply opening 5 at the top of the boiler notifies boiling.

[The problem that the idea aims to solve]

Since a water heater may be used to boil a small amount of water, it is desirable that the minimum standard water level of the water heater is low.

To do this, it is necessary to make the height of the passage 4 as low as possible, but if the height of the passage 4 is made low,
The problem was that hot water was difficult to come out when pouring hot water.

The present invention was made to solve this problem, and it lowers the minimum standard water level in a water heater with a whistle that is installed on the lid that closes the water supply opening at the top of the water heater. The primary objective is to provide a water heater with a whistle that makes it easy to pour water into the water heater. The purpose is to provide water heaters.

[Means to solve the problem]

In order to achieve the above object, the present invention has a spout that protrudes from the surface of the water heater body, and a whistle is provided on the lid that closes the water supply opening formed at the top of the water heater body. In the water heater with a whistle, the height of the lower end surface of the spout is lower than the minimum standard water level of the water heater with a whistle, and the intersection angle between the lower part and the side wall of the water heater body is set. By increasing the size, the area of the opening formed on the lower end surface is increased, and the lower part is made easier to see from above the water heater main body via the water supply opening, and a measuring scale is provided on the outer surface of the lower part. has been established.

[Effect]

In a water heater with a whistle configured as above, the lower end of the spout protrudes into the inside of the water heater body, and the lower end surface of the spout is lower than the lowest standard level, so water is supplied inside the water heater body. When the amount of water is set to a level equal to or higher than the minimum reference level, the lower end surface of the pouring spout is immersed in the water.

Therefore, when the water boiler is heated and the water boils, the steam pressure inside the water heater body is released to the outside via the whistle without leaking from the spout, so the whistle is reliably activated. A blowing sound alerts you when the water is boiling.

Even if the dimension from the lower end face of the pouring spout to the bottom wall of the water heater body is short, hot water does not become difficult to flow because the opening area of the lower end face of the spout is large.

Moreover, when removing the lid of the water supply opening to supply water, the amount of water to be supplied can be determined while looking at the water supply scale that is easily visible from above.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a partially cutaway front view of water heater A with a whistle, and FIG. 2 shows a plan view of water heater A with a whistle with the lid removed.

In the figure, a water heater with a whistle A is a water heater with a whistle that has a whistle 10 on a lid 9 that closes a water supply opening 8 formed at the top of a water heater body 7. However, the structure of the spout 11 protruding from the side surface of the water heater body 7 is different from the conventional one.

The pouring spout 11 has an upper part 11a that projects upward from the surface of the water heater main body 7 and a lower part 11b that projects downward inside the water heater main body 7.
1 penetrates the side wall of the water heater body 7 at a large intersecting angle, and the middle part is fixed by means such as welding or brazing, so that the lower part 11b is inserted from above via the water supply opening 8. You can see it.

Although the distance d between the lower end surface 12 of the lower part 11b and the inner bottom surface 7a of the water heater body 7 is smaller than the height of the minimum standard water level L that regulates the minimum water level of the water boiler, pouring may not be smooth. The dimensions shall not be .

Since the opening area of the lower end surface of the pouring spout 11 is large, the interval dimension d can be made considerably small.

Reference numeral 13 in FIG. 2 is a measuring scale for measuring the amount of water supplied, which is provided on the upper part of the outer surface of the lower part 11b, and is displayed in units of, for example, 0.1 liter.

The measuring scale of conventional water heaters had the disadvantage that it was difficult to see from above the water heater because it was provided on the inner peripheral surface of the water heater body, but the measuring scale of the present invention
3 is located at a position where it can be easily seen from above the water heater main body 7.

Note that the reference numeral 14 in FIG. 1 is a knob provided on the lid 9, and the reference numeral 15 is a handle.

Next, the water heater A with a whistle constructed as described above will be explained.
The effect of this will be explained.

(Water supply) Remove the lid 9 and supply water from above through the water supply opening 8 while looking at the measuring scale 13.

When the water level of the water supply becomes higher than the lower end surface 12, it is confirmed that the water supply has reached the lowest standard water level L.

Further, since the metering scale 13 can be easily seen through the water supply opening 8 from above the water heater body 7, the water supply amount can be controlled while looking at the metering scale.

(Water boiling) When the water supply opening 8 is closed with the lid 9, the space formed above the water surface of the water heater body 7 is sealed from the outside except for the hole of the whistle 10.

When water heater A with a whistle is heated, the steam pressure generated by boiling the water will emit whistle 1 because there is no leakage point.
When the water passes 0, the whistle is blown to alert you that the water has boiled.

When pouring hot water from the spout, since the opening area of the lower end 12 is large, the hot water can be poured smoothly even if the interval dimension d is quite small.

[Effect of idea]

Since the present invention is configured as described above, it produces the effects described below.

(a) If the water level is higher than the lower end of the pouring spout, the whistle will definitely notify you that the water is boiling.

Since the opening area of the lower end of the pouring spout is large, there is an advantage that even if the distance between the lower end and the inner bottom of the water heater body is made quite small, the problem of hot water becoming difficult to come out during pouring does not occur. Therefore, it is possible to lower the minimum standard water level, and a water heater with a whistle that is extremely easy to use is obtained.

(b) Since the pouring spout penetrates the side wall of the water heater body at a large angle of intersection, it is possible to supply water while looking at the metering scale from above when supplying water from the water supply opening.
