Therefore, it is necessary to provide a steam outlet on the top surface of the lid body. Disappear. Moreover, a steam path becomes long and it becomes condensed water before the introduced steam reaches the spout. Furthermore, in the case of an electric kettle configured to be able to pour the liquid in the inner container from the spout by holding the handle and tilting the container body toward the spout, the spout is formed upward. The condensed water condensed through the steam path is refluxed from the spout into the inner container, and even if there is uncondensed steam, it is almost condensed near the spout.

  Therefore, it is possible to prevent the vapor generated in the inner container from going out of the lid. As a result, the child's etc. do not touch the emitted steam, the indoor humidity becomes high, and the problems such as the moisture of the bran and the wallpaper are solved.

(2) The invention of claim 2 The present invention relates to an inner container that contains a liquid, a container body that contains and integrates the inner container, a handle provided on one side of the container body, and an upper portion of the container body. A lid for closing the upper opening of the inner container, a spout provided on the opposite side of the handle portion of the container body, and a heating means for heating the liquid in the inner container, An electric kettle configured to be able to pour the liquid in the inner container from the spout by gripping the handle portion and tilting the container main body toward the spout, and in the lid, While forming the vapor | steam path | route which guide | induces the vapor | steam generate | occur | produced in an inner container, this vapor | steam path | route is equipped with the path | route which goes outside the said cover body, It is characterized by the above-mentioned.

  According to such a configuration, the steam path formed in the lid body is a path that once extends outside the lid body, so that the steam path can be formed longer, and much steam is generated in the steam path. Can be condensed. Therefore, it is possible to prevent the vapor generated in the inner container from going out.

  As a result, the child's etc. do not touch the emitted steam, the indoor humidity becomes high, and the problems such as the moisture of the bran and the wallpaper are solved.

  Moreover, since the steam path once returns from the lid to the lid through the outside, if a temperature detection means such as a bimetal is provided in the passage to the outside, boiling detection can be performed quickly and reliably. As a result, the power can be quickly turned off. Therefore, the generation amount of steam can be suppressed to the minimum possible, and the power consumption can be suppressed to the minimum necessary.

(3) The invention of claim 3 The present invention relates to an inner container that contains a liquid, a container body that houses and integrates the inner container, a handle provided on one side of the container body, and an upper portion of the container body. A lid for closing the upper opening of the inner container, a spout provided on the opposite side of the handle portion of the container body, and a heating means for heating the liquid in the inner container, An electric kettle configured to be able to pour the liquid in the inner container from the spout by gripping the handle portion and tilting the container main body toward the spout, and in the lid, An open / close valve that opens and closes a communication path for hot water pouring that connects the inside of the inner container and the spout is formed by forming a steam path that guides steam generated in the inner container, and the steam path includes: An opening extending near the upper part of the on-off valve, and in the steam path Dew condensation water have been generated are, it is characterized by being configured to dropped on the on-off valve.

  According to such a configuration, the steam path formed in the lid extends near the upper part of the hot water pouring on / off valve that opens and closes the hot water pouring communication path that connects the inside of the container and the pouring port. Since the condensed water generated in the steam path is dripped onto the open / close valve for hot water pouring, the steam that passes through the steam path is operated by opening the on / off valve. Then, even if there is uncondensed steam, it will be poured near the upper part of the on-off valve, so that it will be condensed at that time. As a result, there is no need to provide a steam outlet on the top surface of the lid. Therefore, it is possible to prevent the vapor generated in the inner container from going out of the lid.

  As a result, the child's etc. do not touch the emitted steam, the indoor humidity becomes high, and the problems such as the moisture of the bran and the wallpaper are solved.

  As a result, according to the present invention, an electric kettle with a steam-less structure and high energy saving performance can be provided.

It becomes possible to suppress.

<Second Embodiment>
Next, FIGS. 7 to 13 show an electric kettle according to a second embodiment of the present invention.

  In the case of this embodiment, the steam path 21 has casing walls 22 corresponding to each other from both the upper and lower directions in a space portion between the upper plate 2a and the lower plate 2b in the lid 2 similar to that of the first embodiment. A steam cooling unit B having a chamber structure that introduces steam in the inner vessel 3 and cools and condenses, and a pipe that discharges residual steam cooled through the steam cooling unit B to the inside of the spout 5. It consists of a steam passage 23 having a structure.

  The steam cooling unit B is installed to occupy the semicircular portion of the handle 6 side circular space in the plan view 2 and extends in an oblong shape in the left-right width direction and toward the arc surface of the handle 6 side. The first and second communication passage portions 24a and 24b communicating with the handle portion 6 side steam passage outside the lid 2 having the boiling detection means extend straight in the front-rear direction.

  The steam cooling unit B includes a first partition wall 25a on the second communication passage 24b side, a second partition wall 25b on the intermediate side, a third partition wall 25c on the center side, and a third wall in the oval casing wall 22. A path length in a zigzag shape in a plan view is obtained by alternately extending four partition walls of a saddle-like fourth partition wall 25d provided at the front-end-side bypass portion of the partition wall 25c at a predetermined interval from the opposite surface side. The long steam cooling flow paths 26a to 26d are formed.

  Below the base end side of the third partition wall 25c, an uppermost stream side steam introduction port 21a and a steam introduction passage 21b of the steam passage 21 are provided, and the downstream side of the steam introduction passage 21b extends upward from the lower side. It is opened toward the first connecting passage portion 24a on the handle portion 6 side described above.

  On the other hand, in the downstream portion of the steam cooling channel 26d in the steam cooling unit B, the downstream portion of the steam cooling channel 26d is connected to the upper upper plate 2a of the inner end portion of the spout 5 on the front end side of the lid 2. The base end 23a side of the pipe-like steam passage 23 that is extended and opened in a state of being inclined upward is connected to the back surface portion in a communicating state.

  The steam passage 23 is extended in a shape in which the middle portion of the passage is curved along the front outer peripheral portion of the lid body 2 as shown in FIG. 8 instead of straight, and the extended end 23b is formed as described above. It is opened at a high position above the inner end of the spout 5.

  The opening is communicated with the inner end portion of the spout 5 via a cylindrical portion 29 extending downward from the upper side provided on the lower side.

  For this reason, the dew condensation water generated in the steam passage 23 is returned to the steam cooling flow path 26d in the steam cooling unit B by natural flow without being supplied to the spout 5 side. As shown, since it is supplied to the dew condensation water outlet D that is opened and closed by the on-off valve 14 in the same manner as in the first embodiment, the on-off valve 15 is turned on by the ON operation of the pouring operation section 15 when pouring hot water. When 14 is opened, it is returned into the inner container 3 correspondingly.

  On the other hand, on the inside of the attachment portion 6b portion to the shoulder member 1c portion on the upper end side of the handle portion 6 located outside the lid body 2, it is detected that the water in the inner container 3 has started boiling, Boiling detection means (in this embodiment, bimetal) 10 for turning off the power supply to the heating means (water heater) 4 is provided.

  That is, the handle attachment portion 6b communicates with the first and second communication passages 24a and 24b on the steam cooling unit B side through packings through the openings 32a and 32b on the shoulder member 1c side. A U-shaped temperature detection means installation passage 28 is provided, and an upstream side 28a of the temperature detection means installation passage 28 is provided with a first communication passage 24a to which the steam S from the inner container 3 side is first supplied. Further, the downstream side 28b communicates with the second communication passage 24b.

  And the said boiling detection means 10 is installed in the channel | path U-turn part which connects these upstream channel | paths 28a and downstream channel | paths 28b.

  Therefore, in the case of such a configuration, the steam S at the start of boiling supplied from the inner container 3 side passes through the steam inlet 21a and the steam inlet passage 21b of the steam path 21, and the first in the steam cooling unit B. Is then supplied to the temperature detection means 10 from the upstream side 28a of the temperature detection means installation passage 28 through the opening 32a of the shoulder member 1c provided with the packing P1, with good responsiveness. At the same time, boiling is detected and the power supply to the heating means 4 is shut off.

  Thereafter, the steam S in the same portion passes from the downstream side 28b portion of the passage 28 through the opening 32b of the shoulder member 1c portion and the packing P2, and then from the second communication passage 24b of the steam cooling unit B to the steam cooling passages 26a to 26a. Introduced to 26d, it flows over time while meandering alternately in the left and right directions. In the meandering state, the heat of the steam is dissipated to the wide upper plate 2a side of the lid 2 and condensed and liquefied. It becomes water.

  Since the steam cooling channels 26a to 26d are gradually inclined downward, the condensed water is finally collected in the portion of the steam cooling channel 26d on the most downstream side, and finally the hot water pouring shown in FIG. The dew condensation water outlet D is opened and closed by the open / close valve 14 and is returned to the inner container 3 by opening the open / close valve 14 when pouring hot water.

  The uncondensed steam S that was not condensed in the steam cooling flow paths 26a to 26d was opened above the inner end of the spout 5 while being cooled again through the steam passage 23 as described above. A part of the steam and the steam pressure are directed to the extended end 23b and are released to the spout 5 side through the extended end 23b and the tubular portion 29, and the steam at this time is opened. Since the temperature is not high and the amount is small, it almost disappears in the open space inside the spout 5 and does not come out from the spout 5.

  Therefore, an almost complete steam-less structure can be obtained.

  Although this is not an essential requirement, a part of the temperature detection means installation passage 28 is formed between the side surface side of the container body 1 and the handle portion 6 as shown in FIGS. 7 and 11, for example. You may make it communicate with the downward side surface side steam passage 18 formed in the middle. If it does in this way, dew condensation water which a part of the vapor | steam S which contacted the boiling detection means 10 in the boiling detection part produced | generated by condensation condensation in the process which flows down the side surface side steam channel | path 18 will be made into the lower part side of the handle part 6. It can be discharged to the outside from the opening 18a provided in.

  Other configurations and operational effects are the same as those in the first embodiment, and a description thereof will be omitted.
