Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric water heater in which a steam port is provided on a pushing body that presses a bellows.

Conventional technology Conventional electric water heaters of this type include, for example,
As shown in Japanese Patent No. 59-30612, the structure was as shown in FIGS. 4 and 5.

That is, 51 is a container for storing liquid, and this container 51 is equipped with a heating element 52 and has an upper portion locked to an upper frame 53. 54 is the container 5
1, the lid body is placed on the upper part of the upper frame 53 to maintain airtightness, and has a bellows 55 built therein and a pusher body 56 on the upper part thereof. Reference numeral 57 denotes a through hole provided in the pusher 56. A decorative plate 58 is fitted into the through hole 57, and the decorative plate 58 has a plurality of openings 58a on the top surface. Reference numeral 59 denotes a cover that contacts the lower part of the decorative plate 58 and communicates with the bellows 55 in an airtight manner, and the steam in the container 51 passes through the inside of the bellows 55 to the opening on the top surface of the decorative plate 58. 58a to the outside.

Problems to be Solved by the Invention In such a conventional configuration, when the liquid in the container 51 is heated and boiled by the heating element 52, steam is generated, and the steam passes through the inside of the bellows 55 and is heated to the decorative plate 58. At this time, when the push plate 56 is pressed, most of the steam filling the bellows 55 will flow into the container 51, but some of it will be pushed out. There is a problem in that the flow flows back directly above the pushing body 56 from the opening 58a fitted in the through hole 57 of the body 56, causing burns to the hand pressing the pushing body 56. In addition, since the steam passage is constituted by the pushing body 56, the decorative frame 58, and the cover 59, the number of parts increases, and as a result, the steam seal configuration becomes complicated and costs increase. There was also a problem.

The present invention solves these problems,
If some of the steam filling the bellows flows back due to the pressure of the pusher, the steam will not cause burns to the hand pushing the pusher, and the number of parts can be reduced in terms of structure. To provide an electric water heater which can be obtained at a low cost with a high performance.

Means for Solving the Problems In order to solve the above problems, the present invention provides a container containing a liquid, a heating element attached to the container, a bellows and a steam passage that communicate with the inside of the container in an airtight manner. and a steam port connected to the bellows or the steam passage, and the steam port is integrally formed in an exterior member near a pushing body operating portion that presses the bellows and pours out the liquid in the container to the outside of the container. , and has a ceiling wall with an inclined surface that becomes higher toward the rear of the product on the outside, and has a ceiling wall with an inclined surface that becomes higher toward the rear of the product on the raised wall surface, and has a ceiling wall with an inclined surface that becomes higher toward the rear of the product. This is a wall made of wood with an opening facing outward.

Effect According to the above configuration, even if some of the steam filling the bellows and the steam passage flows back toward the steam port side due to the pressure of the external member, the push body is integrally formed in the external member near the push body operating part. Since the opening of the steam vent is provided facing outward, the steam will not spray out towards the hand pressing the pusher, resulting in the problem of burning the hand. In addition, the steam port is integrally formed with external components such as the lid or pusher, which reduces the number of parts and simplifies the steam seal configuration compared to conventional ones, reducing costs. It can also be obtained at low cost.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 3, reference numeral 1 denotes a container containing a liquid, and has a heating element 2 at the bottom. Reference numeral 3 denotes a flange portion extending outward from the upper end of the container 1. The flange portion 3 allows the container 1 to be attached to the upper frame 5 through the container packing 4 in a watertight manner. Reference numeral 6 denotes a lid body located above the upper frame 5. Inside the lid body 6, there is built-in a bellows 7 that communicates with the inside of the container 1, and the upper end of this bellows 7 is connected to a valve. 8 is welded to the upper plate 9. 10 is a pushing body which is an external member located above the valve 8 via the steam passage 11;
This push body 10 has a ceiling wall 12 which is an inclined surface that becomes higher toward the rear of the product on the outside, and a steam port 14 which has an opening 13 toward the outside and rear in the raised wall surface 12a. are integrally formed. The steam port 14 is connected to the bellows 7 through the cover 11 with a seal packing A1.
5 so as to maintain airtight communication.

16 is a body that covers the outer periphery of the container 1, 17 is a base provided at the bottom of the body 16, and 18 is a handle. A seal packing B 19 is provided at the bottom of the lid 6, and this seal packing B19 holds the container 1 and the lid 6 in an airtight manner.

In the above configuration, the operation will be explained next. When a liquid such as water is placed in a container 1 and the heating element 2 is energized to boil it, steam is generated. This steam flows into the bellows 7 and the steam passage 11 which are in airtight communication with the container 1, and then flows out through the steam port 14 which is in communication with the bellows 7 and the steam passage 11. Thereafter, when the power supply to the heating element 2 is stopped and the pusher body 10 is pressed to pour out the liquid in the container 1, the bellows 7 is compressed by the pusher body 10. As a result, the bellows 7 and the steam passage 11
Most of the steam filling the container 1 is pushed out into the container 1, but some steam flows back out from the steam port 14. In this case, since the steam port 14 has the ceiling wall 12 and the opening 13 is directed outward, the steam does not blow out toward the hand pressing the pusher 10, and as a result, the hand can solve the problem of causing burns to
Furthermore, since the steam port 14 is formed integrally with the pusher 10, there is only one steam sealing portion, which is the contact portion with the cover 11. Therefore, the sealing structure is extremely simple, and there are no parts required. Since the number of points can be reduced, the cost can be reduced.

In the above embodiment, the bellows 7 and the steam passage 11 are connected sequentially from the container 1 to the steam port 14. It goes without saying that the same effects as in the above embodiment can be obtained even in a communicating configuration.

Further, in the above embodiment, the steam port 14 is formed integrally with the pusher body 10, which is an external member, but even if it is formed integrally with the lid body 6, the same effect as in the above embodiment can be obtained. Needless to say.

Effects of the Invention As described above, according to the present invention, there is provided a container containing a liquid, a heating element attached to the container, a bellows and a steam passage that communicate with the container in an airtight manner, and a bellows or a steam passage that communicates with the container in an airtight manner. The steam port is integrally formed in the exterior member near the pushing body operating part that presses the bellows to pour out the liquid in the container to the outside of the product. It has a ceiling wall with an inclined surface that becomes higher toward the ceiling, and an opening is provided in the raised wall surface toward the outside and rear, so that some of the steam filling the bellows and steam passages is Even if the steam flows back to the steam port side due to the pressure of the pusher, the steam will not spray out toward the hand pushing the pusher, and as a result, there will be no problem of burning your hands, and the steam will Since the mouth is integrally formed with the pushing body, the number of parts can be reduced compared to conventional ones, and the steam seal structure can be simplified, making it possible to obtain it at a lower cost. .
