Abstract

PURPOSE:To realize a high finish temperature even when a small quantity of coffee or the like is to be extracted by branching a water pipe from a container to an outlet in the middle, providing a circulating passage to the container, and circulating the hot water in the water pipe via only a button action. CONSTITUTION:A container 2 opened at the upper face is arranged in a main body 1, the upper opening section of this container is covered with a cover 3, and a heating element 4 heating the liquid in the container and an electric pump 5 discharging the liquid to the outside are provided. The outlet of the electric pump 5 is communicated to a valve 9 via the first water pipe 10, the water pipe from the valve is branched into the second water pipe 11 and the third water pipe 12, the second water pipe is communicated to an outlet 13 to the outside, and the third water pipe is communicated to the upper section of the container respectively. The pump and the valve are simultaneously operated by the push action of a button 14. The hot water in the water pipe is circulated, the temperature of the hot water in it can be increased to the temperature of the hot water in the container, thereby a high temperature can be obtained even when a small quantity of hot water is utilized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric water heater that heats and retains the temperature of a stored liquid and discharges it to the outside of the container.

Prior Art A conventional electric water heater has a configuration as shown in FIG. That is, 30 is a main body, and a container 31 with an open top is disposed within the main body 3o, and the top opening of the container 31 is covered with a lid 32. 33 is the container 31
It is a heating element that heats the liquid inside. Reference numeral 34 denotes an electric pump which is a means for drawing out the liquid in the container 31 to the outside of the body. was designed to be led out of the container via a water pipe 38 that communicates the pump 34 with an outlet 37 to the outside of the container.

Problems to be Solved by the Invention However, in such a conventional configuration, the hot water stored in the water pipe 38 easily cools down, and there are cases where the water is kept boiling in the container 31, or when the hot water is left outside the container. After deriving,
After a while, the temperature of the water in the water pipe 38 becomes considerably lower than the temperature of the water in the container 31. When using hot water in this situation, for example, place a regular coffee (hereinafter referred to as "coffee J") device 39 below the outlet 37, and when drawing out the hot water to brew coffee, it is possible to extract one cup of coffee. In the case of a small amount such as
There was a problem in that the ratio of the amount of hot water inside increased, resulting in a significantly lower finished temperature. The same is true when brewing Japanese tea in a teapot.

The present invention solves these problems, and aims to provide an electric water heater that can achieve a high finished temperature even when brewing coffee, etc., even in small quantities. .

Means for Solving the Problems In order to achieve the above objects, the present invention branches a series of paths connecting the lower part of the container and the outlet to the outside of the container, and connects one of the branched paths to the The outlet port is connected to the outlet port, and the other side is connected to the upper part of the container, and a valve is provided at the branching part, and under normal conditions, the passage on the outlet side is communicated with the lower part of the m container, and when the valve is operated, the In this case, an operating section is provided which communicates the passage on the upper side of the container with the lower part of the container and simultaneously operates a discharge means for leading the liquid out of the container and a valve.

Function: The electric water heater of the present invention has the above-described structure, and includes a discharge means for operating the valve to communicate the passage on the upper side of the container with the lower part of the container, and at the same time guiding the liquid out of the container. This allows the hot water in the channel to be circulated and the temperature of the hot water in the channel to be raised to the same level as the temperature of the hot water in the container.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a main body, and a container 2 with an open top is disposed within the main body 1, and the top opening of the container 2 is covered with a lid 3. 4 is a heating element that heats the liquid in the container 2.

Reference numeral 5 denotes an electric pump which is a means for extracting the liquid in the container 2 to the outside of the container.This electric pump 6 is driven by a motor 6. 7 turns motor 6 0N-OFF
This is the first switch to control and is linked to the knob 8.

The discharge port of the electric pump 6 communicates with a valve 9 made up of several parts, which will be described later, via a first water pipe 1o.

A water pipe from the valve 9 is connected to a second water pipe 11. Third water pipe 12
The second water pipe 11 is connected to an outlet 13 to the outside of the container, and the third water pipe 12 is connected to the upper part of the container 2. 14 is a button for operating the valve 9, and by depressing this button 14,
The motor 6 and the valve 9 operate simultaneously.

3 and 4 show the operation unit 15 that operates the motor 6 and the valve 9 at the same time. Reference numeral 16 is a shaft that interlocks with the button 14, and the tip of this shaft 16 has a backing 1γ.
is installed. A case 18 houses the banking 17, and the valve 9 is constituted by the case 718 and the backing 17. 19 is a spring that urges the shaft 16 outward; 20 is a second switch that controls ON/OFF of the motor 6; this second switch 2o is independent of the first switch 7; .

FIG. 3 shows a state in which the button 14 is not pressed; in this state, the first water pipe 10 connecting the container 2 and the valve 9 is connected to the second water pipe 11 connecting the valve 9 and the outlet 13. In this state, when the motor 8 is operated by the first switch 7 linked to the knob 8, the hot water in the first water pipe 10 and the container 2 is led out of the container.

FIG. 4 shows a state in which the button 14 is depressed, and the first water pipe 10 communicates with a third water pipe 12 that connects the valve 9 and the upper part of the container 2, and at the same time the shaft 16
The protrusion 21 formed in the second switch 2o pushes the lever of the second switch 2o to operate the motor 6. As a result, the hot water in the first water pipe 1o circulates, and the temperature of the hot water gradually rises to the temperature of the hot water in the container 2. When the button 14 is no longer pressed, the valve 9 returns to its original state due to the biasing force of the spring 19.

Therefore, if you want the first hot water to be drawn out to have the same temperature as the hot water in the container 2, all you have to do is hold down the button 14 for a while and then operate the knob 8 to draw it out.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
By branching the path from the container to the outlet and providing a circulation path into the container, the hot water in the water pipes can be circulated by simply pressing a button, and the temperature of the hot water can be adjusted to the same level as the temperature in the container. Since it is possible to raise the temperature to the temperature of hot water, it is possible to obtain a high temperature even when using a small amount of hot water, and as a result, it is possible to make the extraction of coffee etc. more ideal. be.
