Description

  The present invention relates to an electric heater having a container that heats and boils the contents, for example, an electric heater such as an electric kettle, an electric pot, and an electric rice cooker.

  Kettles have long been used as so-called “kettles” that simply boil hot water on a stove, but there is an electric kettle that can be easily heated in a few minutes by connecting to a power source and can be easily handled by a handy type. Although it has become widespread, it has a simple structure that does not have a safety structure against the outflow of the contents liquid and the release of steam when the waterfall falls over, with the type that the water heater container is exposed to the outside giving priority to simplicity Was the mainstream. However, the applicant of the present invention has a safety structure (see, for example, Patent Document 1) which is conventionally provided in a lid for closing a container, a lid of an electric pot or the like, and prevents outflow of content liquid and discharge of vapor. An electric kettle has been previously proposed (see, for example, Patent Document 2). On the other hand, the electric rice cooker has a vapor discharge path in the lid, but there is no concern about the falling of the container and no safety measures have been taken against the outflow of the contents. Measures are taken (for example, refer to Patent Document 3).

  However, both the electric pot disclosed in Patent Document 1 and the steam discharge path of the electric kettle disclosed in Patent Document 2 have a problem in that hot water scatters from the discharge port that discharges steam and wets around the discharge port. In particular, it is dangerous to have a handle near the outlet and to hold the handle during boiling. On the other hand, the electric rice cooker is the same as the electric kettle and electric kettle in that it cannot prevent the blowout of the tomb from the steam outlet. Therefore, it is harder to clean than when it gets wet with hot water.

  In view of the above points, an object of the present invention is to provide an electric heater that can prevent hot water from splashing from a steam discharge port or blowing out a rice ball.

In order to solve the above-described problems, an electric heater of the present invention includes a container for heating and boiling the contents, and a steam discharge path for releasing steam generated from the contents boiling by heating by closing the container. A throttle opening that squeezes the middle of the steam discharge path in the vicinity of the upstream side of the steam discharge port of the steam discharge path, and a peripheral wall that is partially open laterally from the edge of the throttle opening. extending passage direction of the steam, and substantially parallel to the opposed dam wall and the aperture area diaphragm as block the flow of vapor from the aperture stop to the extended end of the peripheral wall, the peripheral wall open side of the dam wall One feature is that the throttle opening is provided with a gas-liquid separation portion for separating moisture from the passing steam having a return wall that is returned to the throttle opening side and is opposed to the throttle opening side at the protruding edge of It is said.

In such a configuration, the vapor generated in the container flows into the vapor discharge path of the lid that closes the container, reaches the vapor discharge port, and is discharged outside the lid. The discharged steam is subjected to gas-liquid separation by the throttle through a throttle opening provided in the vicinity of the steam outlet of the steam discharge passage, and at the same time, the speed is increased and flows straight into the gas-liquid separator with high straightness. . The steam that flows into the gas-liquid separation part and tries to go straight forward escapes from the bulging edge of the damming wall toward the opening side of the peripheral wall to the opening side of the throttle wall and escapes to the opening side of the peripheral wall by the return wall facing the throttle opening side. In addition to the restraining guide, it sufficiently collides toward the dam wall facing the diaphragm opening region almost in parallel and reliably receives gas-liquid separation due to the collision. The vapor after the collision gas-liquid separation due to the sufficient collision toward the dam wall tries to flow along the dam wall to the open part of the peripheral wall that is not disturbed, but the bulging edge of the dam wall toward the open side of the peripheral wall Returned to the aperture opening side of the aperture opening and is obstructed by a return wall facing the aperture opening side, and is suddenly turned approximately 90 degrees upstream toward the aperture opening side to undergo gas-liquid separation by centrifugation. The vapor after the gas-liquid separation flows sideways from the opening part of the peripheral wall without the return wall and spreads around the peripheral wall to weaken the accompanying force. It circulates with liquid separation, and is discharged to the outside on the atmospheric pressure side through the vapor discharge port.

The electric heater of the present invention also includes a container for heating and boiling the contents, and a lid having a vapor discharge path for releasing the steam generated from the contents boiling by heating by closing the container. In the vicinity of the upstream side of the steam discharge port of the steam discharge path, a throttle opening for constricting the middle of the steam discharge path is provided, and a peripheral wall partially opened to the side extends from the edge of the throttle opening in the steam passing direction, A gas-liquid separation unit for separating moisture from the passing steam having a damming wall facing substantially parallel to the throttle opening region so as to dampen the flow of steam from the throttle opening at the extended end of the peripheral wall; A draining rib is provided at the aperture opening and extends upstream from the rim of the steam outlet opening on the outer surface of the lid, and the draining rib on the open side of the peripheral edge of the rim of the steam outlet is close to or near the overhanging edge of the damming wall. Contact or overhang edge of dam wall Is another characterized in that either protrudes upstream from the overhanging edge of the proximity or contact with Moreover dam wall.

In such a configuration, the vapor generated in the container flows into the vapor discharge path of the lid that closes the container, reaches the vapor discharge port, and does not separate the gas and liquid by the throttling from the vapor discharge port having the draining rib. Released outside the lid. This discharged steam is subjected to gas-liquid separation by the throttle through a throttle opening provided in the vicinity of the steam discharge port portion of the steam discharge path, increases the flow velocity, and flows straight into the gas-liquid separation portion with high straightness. . Steam to be flowed straight into the gas-liquid separator is surely subjected to gas-liquid separation by substantially parallel toward the opposite damming walls collide sufficiently impinge on aperture Ri opening area. The vapor after gas-liquid separation flows out from the opening of the peripheral wall to the side and spreads around the peripheral wall to weaken the accompanying force, and then goes down to the downstream vapor discharge port on the atmospheric pressure side, downstream from the edge of the vapor discharge port. The power is further reduced while being subjected to gas-liquid separation by centrifugation by detouring the draining rib on the opening side of the peripheral wall facing the surface, and discharged from the steam discharge port to the outside. In particular, if the draining rib on the open side of the peripheral wall is close to or in contact with the overhanging edge on the open side of the damming wall and protrudes upstream from the overhanging edge, it will collide with the damming wall and move laterally from the open part of the peripheral wall. The steam that is about to flow is suddenly turned 90 degrees toward the aperture opening side, subjected to gas-liquid separation by centrifugation, and then suddenly turned 180 degrees outward from the draining rib on the peripheral wall opening side to perform strong centrifugal separation. In response, it detours downstream to the atmospheric pressure side and exits to the steam outlet.

  In the above, the rib on the opening side of the peripheral wall is further positioned between the back side and the inner peripheral wall of the vapor discharge port portion, on the side opposite to the vapor discharge port, and the vapor from which the vapor from the gas-liquid separation unit enters and accumulates A pool space can be formed.

  In such a configuration, in addition to the above, further, the vapor that flows out from the gas-liquid separation unit and tries to escape to the vapor discharge port on the atmospheric pressure side, particularly from the open side of the peripheral wall, tries to escape to the downstream vapor discharge port. Steam with strong power is once introduced into the steam pool space on the anti-steam discharge side on the back side of the draining rib and once swung, and then circulated around the steam discharge port. It is further suppressed.

  In the above, the draining rib on the side of the vapor discharge port on the side opposite to the peripheral wall may be close to or in contact with the side on the side opposite to the peripheral wall of the gas-liquid separator.

  In such a configuration, in addition to the above, the steam that passes through the draining ribs on the gas-liquid separator and the peripheral wall opening side, and that travels from the counter-circumferential wall opening side to the steam discharge port partially opens the anti-circumferential wall of the gas-liquid separator. The draining rib on the side opposite to the peripheral wall can be directed toward the damming steam discharge port to return to the side.

According to the electric heater of one aspect of the present invention, the steam generated in the container is increased in speed by the gas-liquid separation by the throttle through the throttle opening of the steam discharge path, and by the throttle at the throttle opening. Straightly into a gas-liquid separation section having a damming wall facing substantially parallel to the wall, and a return wall that protrudes from the bulging edge of the damming wall to the open side of the peripheral wall and returns to the throttle opening side and faces the throttle opening side. In addition to guidance that suppresses escape to the open side of the peripheral wall by the return wall, reliable gas-liquid separation by collision with sufficient collision with the damming wall, after this collision to the opening of the peripheral wall to the damming wall It is hindered by the return wall provided on the overhanging edge of along the dam wall peripheral wall open side of trying to flow, the gas-liquid separation by centrifugation is about 90 degrees suddenly turn the direction to the aperture open mouth side, 90 degrees After a sudden turn, it flows to the side from the opening part of the peripheral wall without the return wall. It spreads around the wall and weakens the accompanying force, but undergoes four gas-liquid separations by centrifugally turning about 180 degrees to the outer downstream of the return wall and the peripheral wall, so it is accompanied by hot water drops and rice balls. Without going to the atmospheric pressure side, it is released to the steam discharge port and discharged to the outside by a weak force, so that hot water and rice balls can be prevented from being scattered or blown out. In addition, since the steam release force is weak, even if condensed water adheres to the steam discharge port, the blowout to the outside can be suppressed, and it becomes easier to drop as the water droplets grow.

According to another feature of the electric heater of the present invention, the steam generated in the container is increased in speed by at least gas-liquid separation by the throttle through the throttle opening of the vapor discharge passage of the lid, and throttling at the throttle opening. go straight with good flows into the gas-liquid separation unit Te, gas-liquid separation caused by the collision of the collision enough to stop the wall-out dam, associated also spread from the peripheral wall opening after the collision to around the wall to flow out to the side force The gas is separated three times by the centrifugal separation by bypassing the draining rib on the open side of the peripheral wall that goes downstream from the rim of the steam discharge port while the pressure is weakened. since it undergoes liquid separation, Yushizuku and Oneba downstream of the atmospheric pressure side hardly associated, because it is released to the outside by a weak force exits the vapor outlet part, the force while receiving the gas-liquid separator further Drops and grows into droplets by condensation on the rim of the vapor outlet. On hard scatter to the outside, so washable run down quickly by draining rib prior to grow easily size scatter droplets, it is possible to prevent the splashing outside. In particular, if the draining rib on the open side of the peripheral wall is close to or in contact with the overhanging edge on the open side of the damming wall and protrudes upstream from the overhanging edge, the steam works the same as the return wall in one feature. Then, reliable collision separation by sufficient collision of steam with the damming wall, subsequent centrifugal rotation of about 90 degrees, and subsequent centrifugal rotation of about 180 degrees and reduction of blowing force In response to this, it is discharged to the outside without accompanying water drops.

  In addition to the above, the steam that flows out from the gas-liquid separation part and tries to escape to the steam discharge port on the atmospheric pressure side, particularly the steam that tries to escape from the peripheral wall opening side to the downstream steam discharge port, Once it is introduced into the steam reservoir space on the side of the anti-steam outlet, it is introduced into the steam outlet, so that the power of the steam released from the steam outlet is further suppressed, and water droplets and water droplets are scattered outside. The balloon can be suppressed sufficiently.

  In addition to the above, the steam from the gas-liquid separator and the draining rib on the open side of the peripheral wall toward the steam discharge port from the open side of the counter-circumferential wall partially returns to the open side of the counter-circumferential wall of the gas-liquid separator. Since the draining rib on the open side of the anti-circumferential wall is directed to the damming steam discharge port, the low temperature steam that has flowed out to the steam discharge port wraps around the throttle opening side and comes into contact with the high temperature steam to cause condensation. This can prevent the hot water from splashing outside.

  Hereinafter, for example, an electric kettle, an electric kettle, and an electric rice cooker shown in FIGS. 1 to 8 including a prior improvement example for an electric heater having a container for heating and boiling the contents according to the embodiment of the present invention. The description will be made with reference to examples to provide an understanding of the present invention. The following description is one specific example of the electric kettle according to the embodiment of the present invention, and does not limit the description of the scope of claims. Is included. Each feature of the present invention can be employed alone or in combination in various combinations as much as possible.

  The electric heater of the present embodiment is an electric kettle 100 shown in FIG. 1, an electric kettle 200 shown in FIG. 2, an electric pot 300 shown in FIGS. 3 and 4, and an electric rice cooker 400 shown in FIGS. Both adopt a container 1 for heating and boiling the contents, and a lid 3 having a vapor discharge path 2 for closing the container 1 and releasing steam generated from the contents boiling by heating. With electric kettles and electric pots, conventionally, there is a problem that hot water splatters from the outlet that discharges steam and wets around the outlet, and particularly with electric kettles, there is a handle near the outlet and there is a handle during boiling If something happens, it is dangerous. On the other hand, the electric rice cooker is the same as the electric kettle and electric kettle in that it cannot prevent the blowout of the tomb from the steam outlet. Therefore, it is harder to clean than when it gets wet with hot water. Thus, although it has been put into practical use to provide a seal packing that weakens the steam blowing force in the steam discharge path 2, the number of parts and assembly man-hours increase, resulting in high costs.

  Corresponding to this, the present inventors, as in the example of the electric pot shown in FIG. 8, have a throttle opening 4 in the vicinity of the upstream side of the vapor discharge port 2 a of the vapor discharge path 2 of the lid 3 that closes the container 1. A peripheral wall 5a, which is partly open in the circumferential direction, extends from the throttle opening edge 4a in the direction of the passage of steam, and is used as a valve seat for the water stop valve 7 at the time of falling. The improvement which provided the gas-liquid separation part 5 with the damming wall 5b which opposes the area | region of the aperture opening 4 so that the flow of the vapor | steam from the aperture opening 4 was dammed first was performed. According to this, the steam 6 shown by a broken line arrow discharged to the outside through the steam discharge path 2 is subjected to gas-liquid separation by the throttle through the throttle opening 4 to increase the speed, and collides with the damming wall 5b with a straight line. By being subjected to gas-liquid separation by the above-mentioned, without accompanying water droplets or beef, it is discharged downstream from the peripheral wall opening portion 5c to the downstream which is the atmospheric pressure side, and is discharged to the outside from the vapor discharge port 2b through the vapor discharge port portion 2a. However, according to the experiments by the present inventors, the corner of the peripheral wall 5a and the damming wall 5b on the side opposite to the peripheral wall becomes a steam retention area, and the steam is not renewed. It has been found that, since it goes through a simple route as shown by a broken line avoiding the staying area, sufficient collision separation cannot be realized, and hot water cannot be prevented from splashing outside. Further, the vapor 6 that reaches the vapor discharge port 2b with a simple flow and is discharged to the outside touches the rim of the peripheral wall opening side where the speed is high and the outside air of the vapor discharge port 2b is at room temperature. In addition, there is also a problem that the droplets 8 that have grown over time are blown out and scattered.

Therefore, the electric kettle 100 shown in FIG. 1, the electric kettle 200 shown in FIG. 2, the electric kettle 300 shown in FIGS. 3 and 4, and the electric rice cooker 400 shown in FIGS. Thus, a throttle opening 4 for constricting the middle of the steam discharge path 2 is provided in the vicinity of the steam discharge port 2 in the steam discharge path 2, and a peripheral wall 5 a having a part in the circumferential direction opened laterally from the throttle opening edge 4 a. In addition to the damming wall 5b that extends upward, for example, in the direction of passage of 6 and opposes the flow of the vapor 6 from the throttle opening 4 to the extension end of the peripheral wall 5a, substantially parallel to the area of the throttle opening 4 In addition, the moisture accompanying the passing steam 6 having the return wall 5e which is returned to the throttle opening 4 side from the protruding edge 5d of the damming wall 5b toward the peripheral wall opening side and opposed to the throttle opening 4 side, The gas-liquid separator 5 for separating the rice balls It is provided in the mouth 4.

As a result, the vapor 6 generated in the container 1 flows into the vapor discharge path 2 of the lid 3 that closes the container 1, reaches the vapor discharge port 2 a, and is discharged from the vapor discharge port 2 b to the outside of the lid 3. The The discharged steam 6 is subjected to gas-liquid separation by the throttle through a throttle opening 4 provided in the vicinity of the upstream side of the steam discharge port 2a of the steam discharge path 2 as indicated by a broken line arrow in the figure and at a speed. And flows straight into the gas-liquid separator with good straightness. The steam 6 which flows into the gas-liquid separation part 5 and tries to go straight can be prevented from escaping to the open side of the peripheral wall by the return wall 5e, and the dam is opposed to the throttle opening 4 area in parallel with the restricted guide. It sufficiently collides toward the wall 5b and reliably receives gas-liquid separation due to the collision. The vapor 6 after the gas-liquid separation tends to flow along the damming wall 5b to the open portion 5c of the peripheral wall 5a which is not obstructed, but the throttle opening provided at the edge 5d protruding to the peripheral wall opening side of the damming wall 5b. It is obstructed by the return wall 5e that is returned to the 4th side and is opposed to the aperture opening side, and is suddenly turned 90 degrees toward the aperture opening 4 side to undergo gas-liquid separation by centrifugation. The vapor 6 after the gas-liquid separation flows out from the peripheral wall opening 5c without the return wall 5e to the side, spreads outward around the peripheral wall 5a, and weakens the accompanying force, while being almost 180 degrees downstream of the return wall 5e and the peripheral wall 5a. It suddenly turns and turns around with gas-liquid separation by centrifugal separation, and is discharged to the outside at a relatively gentle force from the vapor discharge port 2b through the vapor discharge port portion 2a downstream on the atmospheric pressure side.

Therefore, the vapor 6 generated in the container 1 passes through the throttle opening 4 of the vapor discharge path 2 and gas-liquid separation by the throttle, and the speed at the throttle opening 4 is increased to flow straight into the gas-liquid separation unit 5 with high straightness. Te, a guide that is suppressed the escape of the peripheral wall open side due to the wall 5e returns together, the gas-liquid separation by a reliable collision of colliding enough to the dam wall 5b, which in the open portion 5c of the peripheral wall 5a after the collision Gas-liquid separation by centrifugation, which is interrupted by the return wall 5e so as to flow along the damming wall 5b facing substantially parallel to each other and suddenly turned almost 90 degrees toward the throttle opening 4, and returned after 90 degrees Gas-liquid separation by centrifugation after suddenly turning almost 180 degrees to the outer downstream side of the return wall 5e and the peripheral wall 5a while flowing out from the peripheral wall opening 5c without the wall and spreading around the peripheral wall 5a to weaken the accompanying force. Undergo gas-liquid separation Then, the water drops and rice balls are not accompanied by the atmospheric pressure side, and are discharged to the outside from the steam outlet 2b with a weak force through the steam outlet 2a, and hot water and rice balls are scattered or blown out to the outside. Can be prevented. Moreover, even if condensed water adheres to the steam discharge port 2b due to the weak steam release force, the blowout to the outside can be suppressed, and it becomes easy to drop as the attached water droplets grow. In addition, the vapor-liquid separation part such as steam and the steam discharge port part 2a can be formed and function in a small height range of the steam discharge path 2, and the lid 3 of the electric kettles 100 and 200 that are desired to be bulky is made thin. It is especially effective for.

  Moreover, in the electric kettle 100 shown in FIG. 1, the electric kettle 200 shown in FIG. 2, and the electric pot 300 shown in FIGS. 3 and 4, in addition to the above, the mouth of the vapor discharge port 2 b that opens to the outer surface of the lid 3. A draining rib 11 extending downward at least upstream from the peripheral wall opening side of the edge is provided flush with the mouth edge, and the draining rib 11 on the peripheral wall opening side is close to or in contact with the protruding edge 5d of the damming wall 5b. . Note that the proximity may be one or both of the vertical direction of the damming wall 5b and the opening direction of the peripheral wall.

  As a result, the steam 6 generated in the container 1 and passing through the throttle opening 4 and the gas-liquid separation unit 5 of the vapor discharge path 2 as described above and the gas-liquid separation and the accompanying force are suppressed is on the atmospheric pressure side. In order to escape to the downstream steam outlet 2a, the power was further reduced while undergoing gas-liquid separation by centrifugation by bypassing the draining rib 11 on the peripheral wall open side facing downstream from the edge of the steam outlet 2b, It reaches the vapor discharge port 2b and is discharged to the outside. Therefore, the vapor 6 further weakens the accompanying force and is discharged to the outside from the vapor discharge port 2b, and it is difficult for the droplets due to condensation at the edge of the vapor discharge port 2b to be scattered outside, and further transmitted early by the draining rib 11. Since it is allowed to fall and flow down, it is possible to prevent the hot water from splashing outside.

In this case, since the centrifugal separation by centrifugation with the steam 6 bypassing the draining rib 11 is obtained, it is effective even if the return wall 5e is not essential, and as shown by the phantom line in FIG. If the draining rib 11 is close to or in contact with the overhanging edge 5d on the peripheral wall open side of the damming wall 5b and protrudes upstream from the overhanging edge, it can serve as the return wall 5e, and there is no return wall 5e. Even so, the steam 6 reliably collides with the blocking wall 5b by the guide of the protruding end of the draining rib 11 and tries to flow laterally from the peripheral wall opening 5c by the protruding end of the draining rib 11. After suddenly turning 90 degrees toward the opening 4 side and undergoing gas-liquid separation by centrifugation, it is suddenly turned 180 degrees outward from the draining rib 11 on the opening side of the peripheral wall, and subjected to strong centrifugal separation and downstream on the atmospheric pressure side Detour steam outlet 2a can be released to the outside from the exit steam outlet 2b.

  Further, in the electric kettle 100 shown in FIG. 1, the electric kettle 200 shown in FIG. 2, and the electric pot 300 shown in FIGS. 3 and 4, the draining rib 11 on the opening side of the peripheral wall has the back side and the peripheral wall 2c of the steam discharge port 2a. The steam storage space 12 where the steam 6 from the gas-liquid separation part 5 enters and accumulates is formed between the two and the steam release port 2b side. As a result, the steam 6 that flows out from the gas-liquid separator 5 and tries to escape to the steam outlet 2a on the atmospheric pressure side, particularly the steam 6 that tries to escape from the peripheral wall opening side to the downstream steam outlet 2b, is drained. Since the steam 11 is once introduced into the steam storage space 12 on the side opposite to the rib 11 on the reverse side of the rib 11 and then swung to the steam discharge port 2b side, the force of the steam 6 discharged from the steam discharge port 2b is further increased. It can be suppressed. Water droplets, water droplets splashing outside and blowing out can be suppressed sufficiently.

  Further, in the electric kettle 200 shown in FIG. 2 and the electric pot 300 shown in FIGS. 3 and 4, the draining rib 13 provided near the opening edge on the side opposite to the peripheral wall of the steam discharge port 2 b is provided on the peripheral wall 5 a of the gas-liquid separator 5. Is close to or in contact with the open side of the wall. As a result, the vapor 6 that passes through the gas-liquid separator 5 and the draining rib 11 on the opening side of the peripheral wall and travels from the opposite peripheral wall opening side of the vapor discharge port portion 2 a toward the vapor discharge port 2 b partially reacts with the gas-liquid separation unit 5. The draining rib 13 on the side opposite to the peripheral wall can be directed to the damming steam discharge port 2b to return to the peripheral wall open side. Therefore, the low temperature steam 6 that has flowed out to the steam discharge port 2a circulates toward the throttle opening 4 and contacts the high temperature steam 6 to cause condensation and cause the hot water to be scattered outside. Can be prevented.

  Here, the electric kettle 100 shown in FIG. 1 will be schematically described. It is a handy type electric kettle, which is a container 1 for boiling water by a heater 21, a lid 3 for closing the container 1, a handle 24 provided around the outside of the container 1, and generated in the container 1 into the vapor discharge path 2. A sensor chamber 27 at the top of the handle 24 for introducing a part of the inflowing steam 6 to contact the steam sensor 26, and the sensor chamber 27 from the middle of the steam passage 28 for introducing and discharging the steam 6 from the container 1 side. Is branched into a bag path so that the steam 6 branched from the steam passage 28 into the sensor chamber 27 contacts the steam sensor 26 and returns to the steam passage 28. The steam sensor 26 also serves as an on / off switch for the heater 21. A passive member 131 that is stable at the on position and the off position shown in FIG. An operation button 132 related to the on / off operation and operation of the switch portion 26a of the sensor 26 is connected, and the operation button 132 has an operation portion 132a exposed so that it can be externally operated from an operation window on the upper surface of the handle 24. .

  As shown in FIG. 1, the container 1 is configured by housing a metal inner container 31 made of stainless steel or the like that is heated by a heater 21 in a resin outer case 32. In addition to the vapor discharge path 2 for escaping 6 to the outside, a pouring path 33 for pouring the content liquid toward the spout 38 provided at the front upper end of the container 1 and an opening / closing mechanism 34 for opening and closing the pouring path 33 are provided. It is. As a result, the inner container 31 that is a kettle container is covered with the outer case 32, and the user does not touch it directly to feel hot or burn, and the outer case 32 is made of resin. The heat insulation and the air insulation action between the inner container 31 and the outer case 32 are also helped to suppress the temperature of the outer surface of the container 1, so that the thermal safety when touched is increased. Also, the heating efficiency is somewhat increased due to their heat insulating effect.

  Further, the inner container 31 is closed by the lid 3, and the content liquid can be poured only when the pouring path 33 provided in the lid 3 is opened by the opening / closing mechanism 34, and the container 1 falls down when not pouring including the time of boiling water. Even so, the outflow of the content liquid through the pouring channel 33 can be prevented. Further, the steam 6 passes through a predetermined steam discharge path 2 provided in the lid 3 and is in a predetermined safe position, specifically, the operation unit 35 or the lid 3 of the opening / closing mechanism 34 from the outside of the lid 3. Discharge from the vapor discharge port 2b provided at the rear part of the lid 3 shown in the figure, for example, away from a position where an external operation unit (not shown) located on the left and right of the attachment / detachment mechanism 36 from the outside of the lid 3 is provided. Therefore, the risk of unlimited discharge from the spout 38 of the container 1 can be suppressed, and the water stop function at the time of overturning, that is, the water stop valve 39 at the time of overturn provided in the steam discharge path 2 responds to the overturn of the container 1. Thus, the water stop function that moves to a position that closes the vapor discharge path 2 can prevent the liquid content from flowing out through the vapor discharge path 2 even if the container 1 falls.

  Further, the steam discharge path 2 flows downstream of the vapor discharge port 2b of the lid 3, specifically upstream of the throttle opening 4 and downstream of the water stop valve 39 at the time of falling, when the container 1 falls. It is assumed that a liquid reservoir portion is provided that prevents or delays the accumulation or detour of the liquid to reach the vapor discharge port 2b to the outside of the lid 3. As a result, the lid 3 allows the inside of the inner container 31 to communicate with the outside of the container 1 for the function of the pouring path 33 and the steam discharge path 2, thereby discharging the content liquid and discharging the steam 6 to the outside. Since the outlet channel 33 is reliably closed by the opening / closing mechanism 34 except when the content liquid is poured out, the liquid content flows out of the container 1 through the outlet channel 33 even if the container 1 falls down during non-pouring including when boiling water. Never do. In addition, the lid steam passage 27 is always opened to release the steam 6 generated not only during boiling but also from the steam discharge passage 2 of the lid 3 to the outside, thereby preventing the inside of the container 1 from being pressurized, Even if the container 1 falls and the content liquid flows into the vapor discharge path 2, the content liquid can be stored in the liquid reservoir or detoured to prevent or delay reaching the vapor discharge port 2b.

  Further, since the heater 21 is turned off when the vapor sensor 26 detects boiling, heating can be stopped without special control and electrical equipment on the lid 3 side, and the vapor discharge path 2 is formed from the liquid reservoir. Through the discharge port 2b and the vapor sensor 26, the liquid content can be prevented from reaching the vapor sensor 26 as well as the vapor discharge port 2b even when the container 1 falls. In addition to the steam discharge port 2b, the steam path for sending the steam 6 to the steam sensor 26 may be simply branched from the liquid reservoir.

  Further, the inner container 31 has a cylindrical shape with a substantially straight body, and the sealing member 41 of the lid 3 is closed by abutment from above to a predetermined sealing position. In the region surrounded by the sealing member 41 of the lid 3, the front portion of the outlet opening edge of the pouring channel 33 is located at a position near the front portion of the body wall of the inner container 31 in plan view. Accordingly, it is easy to reduce the distance between them, and the remaining amount with respect to the tilt angle of the container 1 when the content liquid is poured out can be reduced by the reduced amount. In addition, the diameter of the upper end portion of the inner container 31, that is, the inner diameter is the same as or substantially the same as the body diameter, and the lid 3 closes the inner container 31 when the sealing member 41 of the lid 3 abuts from above. It becomes larger within the diameter of the body portion of the container 1, and the pouring path 33, the opening / closing mechanism 34, and the vapor discharge path 2 are satisfied in the lid 3, satisfying the functions required for them, and it becomes easy to collect and arrange them.

  Furthermore, the shoulder 1 and the body of the container 1 are connected to the lower end of the outer case 32 integrally molded with resin by the application screw 43 from the bottom of the bottom of the resin molding. It can be done easily and can be maintained. It is advantageous in terms of heating efficiency, such as adhesion, that the heater 21 is fixed to the bottom of the inner container 31, and the internal power supply device unit 44 to the heater 21 is located in the bottom and is externally provided on the seat 46. The heater 21 is detachably connected to the power supply device unit 45 and supplies power to the heater 21 through the external power supply device unit 45 and the internal power supply device unit 44.

  The electric kettle 200 shown in FIG. 2 is the same as the electric kettle 100 shown in FIG. 1 except for the steam outlet 2b. Therefore, the vapor discharge port 2b will be described in detail. The vapor discharge port 2b is formed of a metal or resin vapor discharge port member 51 which is formed separately from the lid 3 and has the draining ribs 11 and 13 integrally formed. The member 51 is inserted and attached to the opening cylinder part 3a formed on the lid 3 from above with the draining ribs 11 and 13, and the hook parts 11a and 13a provided at the lower ends of the draining ribs 11 and 13 are attached to the opening cylinder. The stopper 3 is elastically engaged with an engaging portion 51a such as a recess or a hole of the portion 3a to prevent it from coming off.

  The electric pot 300 shown in FIGS. 3 and 4 will be schematically described. The container 1 is configured by housing an inner container 31 made of a metal vacuum double container such as stainless steel in an outer case 32. The heater 21 is applied to the single bottom portion of the inner container 31 to heat the liquid content, While keeping warm and storing hot water, use for occasional use. For this purpose, the container 1 extends from the bottom to the outside, rises between the inner container 31 and the outer case 32, enters the overhanging portion 52 where the shoulder portion of the container 1 projects to the front, and is exposed downward from the overhanging portion 52. A discharge path 53 that leads to the discharge port 53a is provided, and an electric centrifugal pump 54 that sends and discharges the liquid content flowing into the discharge channel 53 to the discharge port 53a is connected to the middle of the discharge channel 53, and the lid that closes the container 1 The body 3 is provided with a manual bellows pump 55 that pressurizes the content liquid and discharges the liquid through the discharge path 53. Either pump can be used, but it is convenient to have both. Although not shown in the operation panel 56 on the upper surface of the overhanging portion 52, a hot water supply operation portion for operating the centrifugal pump 54 is provided in addition to various mode setting portions and display portions, and mode setting and hot water supply are provided inside the operation panel 56. A control board 57 for controlling energization of the heater 21 and the centrifugal pump 54 in accordance with operation and temperature information from the temperature sensor 20 is provided.

  The bellows pump 55 pressurizes the content liquid by supplying air into the inner container 31 by a pressing operation by the pressing plate 58 that discharges to the top surface of the lid 3. For this pressurization, the bellows pump 55 has a built-in air supply / exhaust switching valve 59, which is provided in the metal inner lid 61 by opening the air supply port 55a during the air supply operation. The air supply / steam exhaust port 61a is communicated, the communication between the air supply / steam exhaust port 61a and the steam discharge path 2 is disconnected, and the air supply port 55a is restored by a spring (not shown) of the bellows pump 55 after the air supply operation. The air supply / steam discharge port 61a is closed and communicated with the steam discharge path 2.

  The overturn stop valve 39 of the steam discharge path 2 is provided in the vicinity of the upstream of the throttle opening 4 so that the throttle opening 4 serves as a valve seat for the overturn stop valve 39. The lid 3 is connected to the shoulder of the container 1 by a shaft 62 and opened and closed. When the lid 3 is closed, the lock member 63 at the free end is elastically engaged with the front of the opening of the container 1 and automatically closes. The lock is released when the lock release lever 64 is raised and the lock member 63 is moved backward against the spring, and the lock is released. . The discharge passage 53 is also provided with a water stop valve 65 at the time of overturning at a position higher than the full water level at the time of excessive forward tilting or forward tilting to close at the time of falling.

  Both the draining ribs 11 and 13 are integrally formed with the lid 3 together with the steam discharge port 2b, and the draining rib 11 on the opening side of the peripheral wall is the opening on the opening side of the peripheral wall of the steam discharging port 2b for draining as described above. Although provided flush with the edge, the draining rib 13 on the side opposite to the peripheral wall is provided slightly closer to the rear side from the edge on the side opposite to the peripheral wall opening of the steam discharge port 2b. Accordingly, there is an advantage that the dew adhering to the draining rib 13 flows out of the steam discharge port 2b when the lid is opened, and is blocked by the opening edge on the side opposite to the peripheral wall of the steam discharge port 2b.

  Further, as shown by phantom lines in FIG. 4, the peripheral wall 2 c of the vapor discharge port portion 2 a formed integrally with the upper plate 71 of the lid 3 and the middle plate 72 forming the throttle opening 4 of the lid 3. Cost reduction is achieved by providing a sealing cylinder 74 that tightly fits the inner periphery of the peripheral wall 2c at the connecting portion to which the formed connecting cylinder 2d is fitted, thereby omitting the silicon seal packing conventionally employed. I am trying. In order to facilitate close fitting, a chamfered surface 74a is formed by rounding the upper end of the tightly fitting peripheral surface with the peripheral wall 2c of the seal cylinder 74, and is widened by the chamfered surface 74a formed between the connecting wall 2d. A tight fit can be easily achieved by press-fitting the peripheral wall 2c through the opening while being easily positioned. However, since the close fitting can be performed relatively easily without the connection wall 2d, the connection wall 2d is not essential.

  The electric rice cooker 400 shown in FIGS. 5-7 is demonstrated roughly. The container 1 is composed of an inner pot 80 made of metal or non-ferrous metal and a container body 81 that is housed so as to be detachable, and is disposed between the bottoms of the inner case 81a and the outer case 81b of the container body 81. The inner pot 80 itself or the heating element provided in the inner pot 80 is heated by electromagnetic induction by the electromagnetic induction coil 82 to cook rice or keep warm. For this reason, although not shown in the operation panel 95 on the front upper surface of the lid 3, the operation panel 95 has a display unit in addition to the various mode setting units and the rice cooking start operation unit. A control board 97 for controlling energization of the electromagnetic induction coil 82 in accordance with operation and temperature information from the temperature sensor 96 is provided.

  The lid 3 is connected to the rear portion of the shoulder portion of the body 81 by a shaft 82 and opened and closed. When the lid 3 is in the closed state, the engaging portion 83 at the free end which is the front portion of the lid 3 is connected to the front of the body 81. It is locked in a closed state by elastically engaging with a lock lever 84 provided in the section. This lock is released by operating the lock lever 84 to the side where the engagement with the engagement portion 83 is disengaged. The lid 3 is formed hollow by an upper plate 85 and a lower plate 86, and a metal heat radiating plate 87 is attached to the opening formed in the center of the lower plate 86 with a seal packing 88 interposed therebetween, and the inner pot is closed. The inner lid 91 having the seal packing 89 facing the opening 80 is pressed by the seal packing 88 to seal each other, and the inner lid 91 is pressed against the opening of the inner pot 80 by the seal packing 89. It keeps the state. Thereby, the steam generated during cooking is introduced into a wide space between the inner lid 91 and the heat radiating plate 87, and after trying to separate the gas and liquid that escapes from the accompanying rice bowl using the wide space, It is made to discharge | release outside the cover 3 from the vapor | steam discharge path 2 formed between the heat sink 87 and the upper board 85 in the rear part side of the cover body 3. FIG.

  The steam discharge port portion 2a is provided with a pressure separating valve 92 and a seal separation structure for separating a screw that still accompanies the steam 6 passing through the steam discharge port 2b and returning it to the heat radiating plate 87 side. It is mounted so that it can be attached and detached via With respect to the fact that the above-described configuration cannot prevent the blow-off of the rice and the scattering of hot water, the gas-liquid separation unit 5 described above is provided immediately below the vapor discharge port 2a, and the gas-liquid separation unit After sufficient gas-liquid separation at 5, the gas is introduced into the vapor discharge port portion 2 a, and the flow path exits from the gas-liquid separation unit 5 toward the inlet 94 at the lower portion of the vapor discharge port portion 2 a. Is bent to the side extremely low by the steam discharge port 2a, so that the steam 6 and the rice bowl are less likely to accompany the steam 6 toward the inlet 94. Blowing out can be further sufficiently prevented, and no draining rib is provided at the steam discharge port 2b. However, you may provide as needed.

  INDUSTRIAL APPLICABILITY The present invention can be practically used in a steam discharge path of an electric kettle, an electric pot, and an electric rice cooker, and can prevent hot water and rice balls from splashing and blowing out.
