Next, the operation of this embodiment having the above structure will be described.

First, when the opening / closing lever 28 of the lid 26 is pushed,
The hook 41 is pushed backward. At this time, the hinge spring 43
The lid 26 is urged upwards by the
The claw portion of 1 is disengaged from the hole portion 55 of the main body ring 45, and the lid 2
6 rotates about a hinge 27 and is lifted upward. At this time, since there is a gap a between the water discharge pipe 18 and the water purification filter 32, there is no contact. When water 3 which is a liquid is put in the container 2 and the lid 26 is closed and electricity is applied, the temperature sensor 5
Controlled by the control means 51 according to the above information, heating is performed by the heating element 4 to start boiling water.

After a predetermined time (t), the amount of water is judged by the rate of rise of the water temperature, and when the predetermined hot water temperature (θ ₁ ) is reached, the second electric pump 16 is started to operate at a low voltage, and the second electric pump 16 is operated depending on the water amount. After operating for a predetermined time (t ₁ , t ₂ ), water passes through a circulation path like an arrow different from the hot water discharge path, and the water discharge pipe 18
Water is discharged to the space portion 35 of the water purification filter 32 attached to the lid 26 side. As a result, chlorine and the like contained in the water are gradually removed by the adsorption and catalytic action of the purified water containing material 33 such as the activated carbon stored in the water purification filter 32, and the water falls to the surface of the water. . Further, at this time, when the solute substance of the mineral component is contained in the filter, the mineral is eluted.

Further, since the water purifying filter 32 is attached to the lid 26 side, the height of the water purifying filter 32 can be kept low and the height of the water purifying filter 32 mounting portion can be kept low, so that the height of the main body is high. It is possible to keep the height low. In addition, if activated charcoal is left unused in the jar pot for a while, silver will be attached to suppress bacteria even if bacteria should occur. In order to suppress the elution of silver as much as possible, the operation of the second electric pump 16 is stopped before reaching the boiling region. Second electric pump 1
If the electric pump 8 is operated and the hot water is discharged during the operation of 6, the operation of the second electric pump 16 is stopped, and the load on the control means 51 is lightened. is there.

When the water temperature gradually rises and reaches the boiling range,
Further, the steam is discharged through the steam passages of the back cover 30, the inner plug 38, and the steam pipe 37 while discharging the chlorine odor, and is discharged from the steam port 36 of the lid 26. At this time, the steam pipe 37
Since the rear part is in contact with the rear thin part of the main body ring 45 via the steam packing 40, the temperature of the boiling sensor 49 mounted in the main body ring 45 rises, and when the boiling is detected, the heating element 4 is energized. It stops and switches to the heat retention state.

After that, the lock release key (not shown) is pressed to confirm that the hot water discharge lamp (not shown) is lit, and then the hot water discharge key (not shown) is pressed, the switch is turned on by the pushing force.
The number of hot springs changes from 1 to 2 to 3, the voltage applied to the electric pump 8 changes in 3 steps, and the amount of hot water discharged changes stepwise from small → medium → high. The amount of hot water can be adjusted. It should be noted that when tapping hot water, hot water is tapped as indicated by a dashed arrow. In addition, when the amount of hot water becomes small and water is added during the process, the second
The electric pump 16 is operated to circulate and purify water, and then boil and keep warm.

[0025]

As is clear from the above description, since the water filter is attached to the rear side of the lid and the water is discharged upward by the water discharge pipe, the height of the water filter can be kept low and the container Since the space between the full line of water and the lower surface of the back cover can be kept low, the height of the container can be made low and the height of the main body can be kept low, making it easy to use when pouring water in the sink. Is extremely good, and the storability in a shelf or the like is also very good.

Further, since the water purification filter is detachably attached to the lid side with a gap from the water discharge pipe of the circulation path,
When the lid is opened during water supply / drainage, it opens without contact and the bottom and side surfaces of the water purification filter are visible, so you can see how dirty the water stains are and you can easily clean or replace the water purification filter. , It is possible to maintain a good condition in terms of hygiene at all times.

Further, since the two pump system in which the hot water outlet side and the circulation side are constituted by separate electric pumps is adopted, it is not necessary to provide a valve mechanism on the outlet side of the electric pump, and the structure can be simplified and the electric pump can be achieved. The life of the can be extended.

Also, a purified water containing material such as activated carbon is inserted into the purified water filter, and the operation start temperature, operation time and operation voltage of the second electric pump are set to a predetermined temperature, operation time and operation voltage and boiled. Since it is stopped before reaching the area, it has the effect of sufficiently purifying water before tapping, and it is possible to suppress the elution amount of silver impregnated on the activated carbon due to the antibacterial action, which may affect the human body. It can be held down.
