Abstract

PURPOSE:To eliminate the danger of hot water being ejected by mistake during circulation and causing burns by providing motor-driven pumps for ejecting hot water and a motor-driven circulating pump for circulating the water through a circulating line passing through a water-purifying filter thus purifying the water. CONSTITUTION:A container pipe 7 is passed through a hole 6 bored through the front portion of the bottom face of a container 2, and hot water is ejected via a hot water line 15 by driving a first motor-driven pump 8 connected to one end of the pipe 7, the hot water line 15 including a gauge pipe 11, an overturning-preventive valve 12 and a hot water outlet pipe 13. The container pipe 7 is passed also through a second hole 6 bored through the rear of the bottom face of the container 2 and the hot water is circulated via a circulating line 25 by driving a second motor-driven pump 16 connected to the other end of the container pipe 7, the circulating line 25 including a squirt pipe 18 and an extension pipe 23. In that case, the hot water ejected from the squirt pipe 18 is passed through a water-purifying filter 32 freely removably mounted in a filter holder 31 secured to the lower surface of the rear of the back lid cover 30 of a lid body 26 and is thereby purified, and the purified water is dropped into the container 2.

In all of the above-mentioned conventional examples, one electric pump is used for hot water discharge and circulation, and switching is performed by a valve mechanism. Since this valve mechanism switches between the hot water outlet and the circulation path, if hot water is accidentally poured into the hot water outlet during circulation, there is a risk of burns to the user. Therefore, the structure is complicated and the cost is high.

Further, since the hot water discharge path and the circulation path are branched from the valve mechanism, when attempting to simplify both of these paths, the circulation path is limited to the vicinity of the hot water discharge path, and the valve mechanism and the circulation path are restricted. Since the connection mechanism between the path and the container is located in the vicinity, it not only becomes a factor that further complicates the structure, but also the mounting position of the water purification filter is extremely limited.

Further, in the former conventional example, the water purification filter is attached to the side wall of the container, and a space for the attachment portion of the water purification filter is required at the height of the container, which increases the height of the container. Furthermore, the water purification filter becomes dirty with scales as it is purified, but you can see the upper part of the water purification filter, but you have to remove the water purification filter to see the bottom part where the most dirt adheres, so you can not easily check There was a problem.

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 amount of water. 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, the chlorine smell contained in the water is reduced and chlorine etc.
Chlorine, trihalomethane, musty odor, etc. are gradually removed by the adsorption and catalytic action of the purified water containing material 33 such as activated carbon contained therein, and the water falls on the water surface. Further, at this time, when the solute substance of the mineral component is contained in the filter, the mineral is eluted.

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.

【発明の効果】以上の説明から明らかなように、本発明
は出湯側と循環側とを別々の電動ポンプで構成した2ポ
ンプ方式としたので出湯側の電動ポンプの出口側に複雑
な切替弁機構を設ける必要がなくなり、また液体の循環
中に誤って出湯路に湯を流して使用者に火傷を負わせる
危険性もなく、安全性に優れ、構造も簡略化できるので
原価的にも有利となるばかりか、電動ポンプの長寿命化

ジャーポット製品自体の基本性能を失うことになり製品
寿命に大きく係わる。このため出湯側の電動ポンプの寿
命を向上させることは製品の寿命を向上させる。
As is apparent from the above description, the present invention employs a two-pump system in which the hot water supply side and the circulation side are separate electric pumps, and therefore a complicated switching valve is provided at the outlet side of the hot water supply side electric pump. There is no need to install a mechanism, and there is no risk of accidentally pouring hot water into the hot water outlet while the liquid is circulating, which could cause burns to the user, excellent safety, and the structure can be simplified, so it is cost effective. In addition, the life of the electric pump can be extended. In particular, if the electric pump on the hot water outlet side fails, the basic performance of the jar pot product itself will be lost, greatly affecting the product life. Therefore, extending the life of the electric pump on the tap water side extends the life of the product.

Even if the hot water discharge path and the circulation path are shortened and simplified, the circulation path is not limited to the vicinity of the hot water discharge path and the structure can be simplified. Therefore, the position of the water filter is not limited, and the water filter can be arranged at any position.

Further, since the water purification filter is detachably attached to the lid side, the bottom surface and side surfaces of the water purification filter can be seen when the lid is opened during water supply / drainage, so that the degree of dirt such as scale can be known, and the water purification filter can be cleaned. And can be easily replaced, and has a great effect that a good condition can be maintained at all times in terms of hygiene.
