Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric water heater for heating and keeping a contained liquid warm.

BACKGROUND OF THE INVENTION Conventional electric water heaters with electric pumps have a motor installed in the lid, and the liquid inside the container is pumped up through a pipe hanging inside the container. There was a method in which the liquid was discharged outside the body, and a method in which a pump was installed below the outside of the container, and the pump was guided through a pipe from the bottom of the container to the pump, and the pump was guided upwards by a sive vibrator to be discharged outside the container.

Problems to be Solved by the Invention However, such a conventional configuration has the following problems. First, in the former method in which a motor is provided in the lid, since the electric part is located in the lid, it is necessary to run electrical wiring between the main body and the lid, which results in a complicated structure. In addition, the lid had a motor, making it heavy, and the long pipe protruding from the lid made it difficult to attach and remove the lid, which caused many problems in terms of construction and operability.

In addition, in the latter method, a pump is installed below the outside of the container and the liquid inside the container is pumped up from the lower part of the container using a vibrator.
Since the pump is inside the container, it is relatively simple in terms of construction, and the liquid located in the pikes located in front and behind the pump is heated and does not need to be attached or removed. When discharging outside the container, even if the liquid in the container is at a high temperature, the liquid in the pump flow path is at a low temperature, and the pump flow path is also at a low temperature, so the discharged liquid has a temperature higher than the temperature inside the container. There was a problem that it fell down and was not easy to use.

Means for Solving the Problems In order to solve the above problems, the present invention provides a bottomed cylindrical container, a main heating element that heats the liquid in the container to a high temperature, and a main heating element that heats the liquid heated to a high temperature. The apparatus includes an auxiliary heating element for heat retention, and a pumping type electric pump that is located outside the container and provided inside the container and discharges the liquid in the container to the outside of the container, and is connected in series with the auxiliary heating element. A small capacity heating element,
It is installed closely in the case of an electric pump.

Function According to the above configuration, since the electric pump is located inside the container, the electric wiring configuration is simpler than when the electric pump is installed on the lid, and the weight of the lid can be reduced. Since there are no pipes hanging down from the lid, the operability of the lid is greatly improved.
In addition, a small volume heating element is placed closely in the case of the electric pump, so not only the liquid in the container but also the liquid in the electric pump and its flow path is sufficiently heated. As a result, the temperature of the liquid discharged outside the container is also maintained at a temperature sufficient for cooking, etc.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. In the figure, reference numeral 1 denotes a container body that covers a container 2, a spout 3 is fixed to the upper opening of the container body 1, and a hook 4 is integrally attached to the lower end of the container body 1. 6 is spout 3
It is a lid body that covers the spout 3 so as to be openable and closable, and is configured with a button so that it can be attached to and detached from the spout 3 by pressing a lock knob 6 provided on the front surface of the lid body 5.

7 is a steam port, and this steam lower communicates with the inside of the container 2. Reference numeral 8 denotes a guide vane hole provided on the bottom surface of the container 2, and this guide hole 8 is located outside the container 2 through an abbreviated waterproof backing 9 made of silicone rubber or the like. A pump-type electric pump 1 installed inside the container body 1
It is connected to the inlet 11 of o. In this electric pump 10, the blades in the electric pump 1o are rotated by a motor 12, and the liquid in the container 2 is pumped out. 14, a water pipe bushing 16 with a built-in outflow prevention valve 15 is energized, and the water is discharged from the discharge port 17 through the discharge pipe 19 in the nose 18 to the outside of the vessel.

On the back side of the bottom of the container 2, there is a heating element made of a metal with good thermal conductivity such as aluminum or steel, in which insulating plates are laminated on top and bottom and a main heating element 20 and an auxiliary heating element 21 are integrally formed. A ram 24 is fixed to the multi-composed heat diffusion plate 22 and back plate 23 in a crimped state.
25 is a second temperature regulator that controls ON/OFF of the auxiliary heating element 21; 26 is a cord-shaped 6-page heating heat generator provided closely on the case of the electric pump 100; body, 27I'i, motor 12 ON-OFF
It is a switch for

Figure 2 shows the electric circuit of an electric water heater, in which the heating element 26 and the auxiliary heating element 21 are connected in series.
It is controlled by a second temperature regulator 25. Therefore, the heating element 26 is energized at the same time as the auxiliary heating element 21.

While the heating element 26 is energized, not only the liquid inside the electric pump 10 is heated but also the convection
The liquid in the outlet pipe 14 is also heated, increasing the temperature of the liquid. This makes it possible to obtain a high temperature that is the same as the liquid temperature in the container 2, and as a result,
A decrease in discharge temperature can be prevented.

Effects of the Invention As is clear from the description of the embodiments above, the electric water heater of the present invention has an electric pump located outside the container and inside the container. Compared to this, the electrical wiring is simpler, the weight of the lid can be reduced, and there is no pipe hanging from the lid, so the operability of the lid can be greatly improved. In addition, since a small-capacity heating element is installed closely in the case of the electric pump, it is possible to ensure that not only the liquid in the container but also the electric pump and the liquid in its flow path are sufficiently heated. As a result, the temperature of the liquid discharged outside the container can also be maintained at a temperature sufficient for cooking, etc.
